RELATED APPLICATIONS

[0001] This application is a continuation-in-part of U.S. non-provisional patent application Ser. No. 19 / 317,014, filed Sep. 2, 2025, to Edward Schoen, titled “Kneeling Support Device and System,”, which is a continuation-in-part of U.S. non-provisional patent application Ser. No. 18 / 310,081, filed May 1, 2023, to Edward Schoen, titled “Kneeling Support Device,” and claims the benefit of U.S. provisional patent application 63 / 341,138, filed May 12, 2022 to Edward Schoen, titled “ToeKnee Crawler,” the entirety of the disclosures of which are hereby incorporated by this reference.TECHNICAL FIELD

[0002] This document relates to the field of kneeling support devices and systems. More specifically, the present disclosure relates to joist support platforms and a support cushion that easily attaches to the leg from the knees down to the foot. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present disclosure are also equally applicable to other like applications, devices, and methods of manufacture.BACKGROUND

[0003] By way of background, this disclosure relates to improvements in kneeling support devices. Generally, people who kneel for long periods of time throughout the day for work and other tasks may experience significant discomfort in the lower leg, ankle, and knee area. Further, blood flow restriction can cause pain to the feet and toes, resulting in a pins and needles type feeling in the extremities. Additionally, numbness can occur due to the increased lower leg pressure and may cause health issues if this process is repeated for several weeks and months at a time.

[0004] Typically, knee pads are widely used by landscapers, mechanics, plumbers, housekeepers, and other occupations requiring a kneeling position. Furthermore, existing kneeling devices which a user places on the ground to use, tend to shift around and slide. Further, prior art knee and shin pads can interfere with leg circulation when they are wrapped too tightly around the knee and / or shin. Further, some knee and shin pads are configured to be placed in pockets within the legs of pants. However, a user is limited to only that pair of pants.

[0005] Thus, there is a need for a kneeling support device that cushions and supports users who have to kneel for long periods of time throughout the day. Further, there is a need for a kneeling support that attaches to the user and does not slide around but is also not limited to one article of clothing.

[0006] There is also a need for devices that allow users to safely navigate across the top of joists in attics. Attics are confined spaces where improper placement of one's knee or leg can lead to punching a hole into the ceiling below.

[0007] Therefore, there exists a long-felt need in the art for a kneeling support device that provides users with a support cushion that easily attaches to the leg, from the knees down to the foot. There is also a long-felt need in the art for a kneeling support device that offers comfort and relief to the knees, lower leg area, toes and feet while in a kneeling position for extended periods of time. Further, there is a long-felt need in the art for a kneeling support device that can be used while carpet laying, roofing, plumbing, floor tiling or installation, etc. Moreover, there is a long-felt need in the art for a device that alleviates the pressure felt on other areas of the body due to shifting of a user's body weight for balance or a comfortable kneeling position. Further, there is a long-felt need in the art for a kneeling support device that features a lightweight, portable design that can be easily placed and secured on a user's leg and removed. Further, there is a long-felt need in the art for a kneeling support device that utilizes hook and loop fasteners to secure the device to a user's leg. Finally, there is a long-felt need in the art for devices that improve stability and reduce the likelihood of damaging the ceiling mounted to attic joists.SUMMARY

[0036] Detailed aspects and applications of the disclosure are described below in the following drawings and detailed description of the technology. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. In the drawings and detailed description, like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the disclosure can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the disclosure and do not limit the scope of the disclosure. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0037] As noted above, there is a long-felt need in the art for a kneeling support device that provides users with a support cushion that easily attaches to the leg, from the knees down to the foot. There is also a long-felt need in the art for a kneeling support device that offers comfort and relief to the knees, lower leg area, toes, and feet while in a kneeling position for extended periods of time. Further, there is a long-felt need in the art for a kneeling support device that can be used while carpet laying, roofing, plumbing, floor tiling or installation, etc. Moreover, there is a long-felt need in the art for a device that alleviates the pressure felt on other areas of the body due to shifting of a user's body weight for balance or a comfortable kneeling position. Further, there is a long-felt need in the art for a kneeling support device that features a lightweight, portable design that can be easily placed and secured on a user's leg and removed. Finally, there is a long-felt need in the art for a kneeling support device that utilizes hook and loop fasteners to secure the device to a user's leg.

[0038] The present disclosure, in one exemplary embodiment, is a novel kneeling support device. The device is an attachable, comfortable support device that may be applied to the leg of a user and extends from the knees down to the instep of the foot to help reduce the amount of pressure on the feet and toes of a user. The kneeling support device comprises a base component that is configured in a curved contour that wraps around the front of a user's leg and foot. The outer surface of the base component comprises at least one padding layer to cushion a user's knees and shins, while kneeling. The end of the base component near the foot comprises a cutout component that curves around a user's foot to provide comfort and support to the toes and feet while kneeling. Further, the base component comprises a large hook and loop fastener wrap that is secured around a user's calf for adhering the device to a user. The present disclosure also includes a novel method of supporting and cushioning a user's knees and shins. The method includes the steps of providing a kneeling support device comprising a base component that is configured to wrap around the front of a user's leg and foot. The method also comprises engaging the cutout component around a user's foot. Further, the method comprises positioning the base component around a user's shin and knee. Finally, the method comprises securing the device to a user's leg via hook and loop fasteners.

[0039] Referring initially to the drawings, FIG. 1 illustrates a perspective view of one embodiment of the kneeling support device 100 of the present disclosure. In the present embodiment, the kneeling support device 100 is an improved kneeling support device 100 that provides a user with comfort and support when kneeling for extended periods of time. Specifically, the device 100 is an attachable, comfortable support device 100 that may be applied to the leg 104 of a user 112 and extends from the knees 106 down to the instep of the foot 108 to help reduce the amount of pressure on the feet 108 and toes 110 of a user 112. The kneeling support device 100 comprises a base component 102 configured in a curved contour to the shape of a user's leg 104 and knee 106.

[0040] Further, the outer surface 114 of the base component 102 comprises at least one padding layer 116 to cushion a user's knees 106 and shins 118, while kneeling. The end 120 of the base component 102 near the foot 108 comprises a cutout component 122 that curves around a user's foot 108 to provide comfort and support to the toes 110 and feet 108 while kneeling. In use, the user 112 engages the cutout component 122 around the foot 108 before attaching the hook and loop fastener strap 124 around the calf area to its desired tightness. The device 100 rests on top 126 of the foot 108 and wraps tightly around each side 128 of the foot 108 to keep the device 100 in place. Accordingly, the kneeling support device 100 is then kept in place while in use. The cutout component 122 is sized and shaped to fit and engage the ankle near the talus bone of user 112 and near the top of foot 126. The cutout component 122 may have a generally arch-shaped topography. The cutout component 122 may have a span of 2″-6″, 3″-5″, 2.75″-5.5″, or 3″-4″, and have a rise of 1″-10″, 1″-8″, 1″-7″, 2″-6″, 4″-6″, or 3″-5″.

[0041] Generally, the kneeling support device 100 supports and cushions a user's knees 106 and legs 104 while kneeling for extended periods of time. Generally, the kneeling support device 100 comprises both a rigid knee shield 130 for covering a substantial part of a front surface of user's knee 106 and a rigid shin shield 132 for covering a substantial part of a user's shin 118. The rigid knee shield 130 and the rigid shin shield 132 can be separate components secured together in use or can be an integral one-piece component, depending on the needs and / or wants of a user. The kneeling support device 100 can be any suitable shape and size as is known in the art. Further, the kneeling support device 100 can be available in multiple sizes, depending on the height and / or size of a user's legs 104.

[0042] As shown in FIG. 2, the end 120 of the base component 102 near the foot 108 area comprises a cutout component 122 that curves around a user's foot 108 to provide comfort and support to the toes 110 and feet 108 while kneeling. In use, the cutout component 122 is engaged around a user's foot 108 before attaching the rest of the base component 102. Thus, once the device 100 is in position, the cutout component 122 rests on top 126 of the foot 108 and wraps tightly around each side 128 of the foot 108.

[0043] Further, the base component 102 comprises securing components 124 on either side. The securing components 124 act to secure the base component 102 around a user's leg 104 and knee 106. The securing components 124 include buttons, snaps, hook-and-loop fasteners, zippers, or other suitable fasteners operable to temporarily attach the base component 102 around a user's leg 104 and knee 106. In one embodiment, hook and loop fasteners 124 are used to secure the device 100 around a user's calf. In another embodiment, hook and loop fasteners 124 are used to secure the device 100 around a user's calf, knee 106, and ankle. Generally, any suitable number of hook and loop fasteners 124 can be utilized as is known in the art, depending on the needs and / or wants of a user.

[0044] Generally, the hook and loop fasteners 124 allow the user 112 to set a specific tightness to the device 100 around their leg 104. Thus, if another user 112 wears the device 100, or if the size of the user's leg 104 grows or increases, the length of the hook and loop fasteners 124 can be adjusted again via the hook and loop fasteners 124. Thus, the hook and loop fasteners 124 can be secured around a user's leg 104 to any desired tightness as is known in the art.

[0045] As shown in FIGS. 3-4, the device 100 comprises a base component 102 that is configured to contour to both a user's legs 104 and knees 106. Specifically, the base component 102 comprises an outer surface 114 and an inner surface 300. The inner surface 300 is configured in a curved contour that wraps partially around the front of a user's leg 104 and knee 106. Specifically, the curved contour of the base component 102 creates a recess 302 on the inner surface 300 of the base component 102, which contours to a user's leg 104. Recess 302 has a depth of at least 1″ (e.g., 1″+, 1.5″+, 2″+, 2.5″+, etc.) in various embodiments. The recess 302 runs the entirety of a portion of the length of the base component 102, for example, 100%, 70-100%, 55-85%, 65-75%, 30-80%, or 40-75% of the length from the apex of the cutout component 122 to the top end of the base component 102.

[0046] Furthermore, the outer surface 114 comprises multiple layers. Generally, the multiple layers comprise padding layers 116 and support and cushioning layers. In one embodiment, the outer surface 114 comprises a protective barrier layer 304. The multiple padding and cushioning layers 116 are flexible and conform to a user's knee 106 and leg 104. The protective barrier layer 304 is a hard plastic layer that is generally shaped to fit the outer-facing region of the knee 106 and shin 118. The protective barrier layer 304 is typically not flexible and may stay straight as a user 112 bends a knee 106. The protective barrier layer 304 may be detachable from the multiple padding and cushioning layers 116 and protects a user 112 from abrasions, scratches, and discomfort. Further, the multiple layers 116 can be flexible, resilient, and / or water-resistant, and may be made of natural or synthetic materials, such as foams, sponges, gels, or other compressible materials known to those of skill in the art.

[0047] In one embodiment, the optional protective barrier layer 304 can comprise a shell, a covering or a jacket placed over the layers 116 as necessary for field or work conditions. The protective barrier layer 304 can manufactured of various materials, such as polycarbonate, polyethylene, PVC, ABS, etc., or other hard plastic materials known to those skilled in the art. The protective barrier layer 304 can be any suitable color or design depending on the use of the device 100 and can even be camouflaged for hunters, such as green camouflage for bush or field hunting or brownish / grayish for duck hunting.

[0048] Additionally, extra padding and / or layers can be added to selected portions of the base component 102, such as around the knee 106 as desired. Further, while the aforesaid device 100 is designed for use in work or field conditions, it is also noted that the device 100 may be used domestically in a house or apartment for users 112 who have knee conditions which require padding during normal household chores, such as cleaning floors or gardening.

[0049] As shown in FIG. 5, the kneeling support device 100 is secured over a garment 500, such as overall pants, leggings, work pants, etc., or other types of garments 500. Further, a user 112 may also wish to use the device 100 while wearing shorts or a short skirt, for example. Here, the kneeling support device 100 can be secured directly around a user's legs 104 and knees 106.

[0050] Generally, the kneeling support device 100 may be used in a variety of applications. For example, the kneeling support device 100 may shield and protect a user 112 while they are kneeling on a hard surface and installing new carpeting, landscaping, roofing, etc., or while standing on a ladder and leaning their knees 106 and shins 118 on the ladder.

[0051] In yet another embodiment, the kneeling support device 100 comprises a plurality of indicia 502. The base component 102 of the device 100 may include advertising, trademark, other letters, designs, or characters, printed, painted, stamped, or integrated into the base component 102, or any other indicia 502 as is known in the art. Specifically, any suitable indicia 502 as is known in the art can be included, such as, but not limited to, patterns, logos, emblems, images, symbols, designs, letters, words, characters, animals, advertisements, brands, etc., that may or may not be knee, support, cushion, or brand related.

[0052] FIG. 6 illustrates a flowchart of the method of supporting and cushioning a user's knees and shins. The method includes the steps of at 600, providing a kneeling support device comprising a base component that is configured to wrap around the front of a user's leg and foot. The method also comprises at 602, engaging the cutout component around a user's foot. Further, the method comprises at 604, positioning the base component around a user's shin and knee. Finally, the method comprises at 606, securing the device to a user's leg via hook and loop fasteners.

[0053] FIGS. 7A, 7B, 8, 9A, and 9B depict various views of non-limiting embodiments of kneeling support device 100. Base component 102 of kneeling support device 100 includes a padding layer 716 coupled to a support layer 705 (padding layer 116 discussed herein shares all or some of the features of padding layer 716, and vice versa, according to various different embodiments). In some embodiments, padding layer 716 is releasably coupled to support layer 705 or other elements of base component 102 (e.g., using hook and loop fasteners, compression fittings, or other releasable fastening devices). When a user 112 wears kneeling support device 100, the user's knee 106 is positioned near the knee end 740 and their ankle is located in or below cutout 122 at base end 120. Base component 102 may be constructed primarily of a foam polymer. In some embodiments, one or both of support layer 705 and padding layer 716 are primarily constructed of a closed-cell foam, an open cell foam, gel foam, memory foam, or other material providing compression capabilities. One or both of support layer 705 and padding layer 716 may be partially or fully constructed using closed-cell polyethylene foam. Padding layer 716 may have a higher density or higher rigidity than support layer 705, for example, a closed-cell polyethylene foam of padding layer 716 is 1.1-3.5 times, 2-6 times, 5-10 times, 8-25 times, 1.1-9.5 times, or 1.1-25 times denser than a closed-cell polyethylene foam of support layer 705 (different foams or different materials may have different ranges and ratios of density). Both the support layer 705 and padding layer 716 may be substantially constructed using closed-cell polyethylene foam where padding layer 716 has a higher density than support layer 705. Many elements of base component may be constructed of injection molded foam, machined or cut foam, or other methods of shaping foam parts. The density of support layer 705 provides structure for the base component 102, proper leg 104 fitment to improve operability during use, and physical comfort as the recess 302 conforms or fits the user's leg 104 during use (see FIGS. 2 and 8). The density of padding layer 716 offers a tough surface that can endure abuse during rugged construction conditions, increases the rigidity of base component 102, and provides a uniform surface engaging the floor and distributing the user's 112 weight more evenly.

[0054] Grip member 750 is located on the outer surface 114 or underside of base component 102. For example, when base component 102 includes a padding layer 716, grip member 750 is located on the underside of padding layer 716 to provide increased grip of objects located below user 112 when kneeling (e.g., joist 850 shown in FIG. 8). Grip member 750 may have a generally concave shape. Grip member 750 may be sized and shaped to fit a particular intended object, for example, the 1.5″ edge of dimensional lumber, engineered wood or joists, engineered “I” joists, and so forth (see FIG. 8 depicting a joist 850). For example, grip member 750 may be wider than a 1.5″ dimensional lumber edge to allow the grip member 750 to better engage a joist 850 of dimensional lumber and reduce the odds the user 112 will slip off the joist 850. As another example, grip member 750 is over 2.5″ wide, which can accommodate joists 850 made from 2× dimensional lumber and numerous engineered “I” joists, but not larger 4×_dimensional lumber and larger engineered “I” joists (e.g., 3.5″ wide joist tops).

[0055] The grip member 750 may be constructed of a durable and semi-rigid material that is also flexible and conformal (e.g., a foam, polymer, closed-cell foam, etc.) to help grip member 750 engage the object below and reduce slippage. Grip member 750 may have a textured surface, a contoured surface, a concave shape, or other gripping feature. Grip member 750 may be constructed of multiple layers and be constructed of the same or different materials than base component 102, support layer 705, or padding layer 716. In some embodiments, padding layer 716 is thicker than padding layer 116 to retain sufficient thickness due to reduced thickness at the thinnest portion of a concave grip member 750.

[0056] Grip member 750 is located at least at the upper end to allow gripping pressure to increase beneath the weight under knee 106 of user 112. Grip member 750 may be located within the first 4″ to 8″ of the knee end 740, for example, near padding knee end 742 located on padding layer 716 or near support layer knee end 744 if base component 102 has a unibody construction or otherwise omits or incorporates padding layer 716 into support layer 705. Grip member 750 may be positioned with knee placement 752 situated directly below knee 106 during use with drip member 750 extending above and below knee placement 752 by several inches (e.g., 1″, 2″, 3″, 4″, 5″, 6″, and so forth). In some embodiments, grip member 750 runs up to one quarter, one half, three-quarters, or the full distance from the knee end 740 (e.g., padding knee end 742 or support layer knee end 744) to the base end 120 or padding ankle end 720.

[0057] During use, the knee 106 of user 112 is positioned in recess 302 to be directly over the knee placement 752. Knee placement 752 is positioned to direct the pressure from knee 106 onto the object below (e.g., a joist) and increase the conformal grip of grip member 750 on the object. In some embodiments, the base component 102 and recess 302 are sized and shaped so the knee 106 is positioned above the knee placement 752. Grip member 750 may be sized and shaped in conjunction with recess 302 and cutout 122 to guide user 112 in proper knee 106 placement over grip member's 750 knee placement 752 by engaging cutout 122 into the ankle of user 112 near the talus bone (e.g., top of foot 126 area) and bringing the recess 302 to engage with the leg 104 and shin 118, thereby placing the knee 106 in line with knee placement 752 and allowing straps 760 to secure base component 102 in the correct position on the leg 104.

[0058] Kneeling support device 100 includes a flashlight 790 coupled to base component 102 in certain embodiments. Flashlight 790 can be an off-the-shelf flashlight, a custom flashlight, or another light source. Flashlight cavity 792 is a cavity deep enough to securely hold flashlight 790 in place during normal use (e.g., compression fit) but also allow for the removal of flashlight 790 to replace batteries, recharge, and so forth. Flashlight fastener 794 may be added to help secure flashlight 790 in the flashlight cavity 792. Flashlight fastener 794 can be an among a variety of fasteners, including hook-and-loop fasteners, clasp(s), latch(es), and so forth.

[0059] Kneeling support device 100 includes at least one structural support member 770 in various embodiments. Structural support member(s) 770 operate to increase strength and rigidity of the base component 102. If base component 102 is too flexible, the kneeling support device 100 will bend or contort when spanning a distance (e.g., bridging the distance between joists), applying most of the load near the middle or shin 118 area, or other use cases. Structural support member(s) 770 are constructed of strong and rigid materials like thermoset polymers, thermoplastic polymers, metal, polymers, fiber-reinforced polymers, and so forth. In some embodiments, structural support member(s) 770 are tubular rods of fiberglass or another fiber-reinforced polymer. Many different shapes and sizes of structural support member(s) 770 will increase rigidity and performance, and many different placement locations are contemplated herein. While FIG. 7B shows structural support member(s) 770 embedded inside support layer 705 in structural support cavity 772, the structural support member(s) 770 can be located elsewhere on, around, or inside kneeling support device 100 to provide sufficient increases in rigidity. Structural support member(s) 770 run generally parallel to the long axis of base component 102 in numerous embodiments.

[0060] Akin to the discussion of strap 124 elsewhere herein, kneeling support 100 includes at least one strap 760 to secure the base component 102 to the leg 104. For example, an upper strap 760A passes via feed through pair 762A while a lower strap 760B passes via feed through pair 762B, thereby allowing straps 760 (i.e., 760A &760B) to secure around leg 104 for use. Each strap 760 has a first end 765 and a second end 766 that fastens to first end 765. For example, first end 765 and second end 766 may include hook-and-loop fasteners (e.g., where second end 766 includes a longer section of loops than hooks on first end 765 to make straps 760 adjustable around different leg 104 diameters). Access ports 764 (e.g., upper access port 764A and lower access port 764B) allow user 112 to thread or unthread straps 760 in or out of feed through pairs 762 while padding layer 716 remains coupled in place to support layer 705. The access ports 764 allow for replacement of damaged straps 760 or installment of different sizes or types of straps 760.

[0061] FIG. 8 illustrates non-limiting embodiments of kneeling support device 100 positioned on a joist 850 as discussed above. Base component 102 includes vent grooves 800 according to various embodiments. Vent grooves 800 may include an upper section 802 and lower section 804. Vent grooves 800 include a plurality of grooves or contours encouraging air flow and ventilation to draw heat and sweat away from leg 104. The plurality of grooves of vent grooves 800 may be substantially parallel to each other or may intersect each other. For example, the plurality of grooves of vent grooves 800 may intersect each other generally orthogonally at right angles or intersect each other at any angle between 1° and 180°. In some embodiments, the pattern of intersecting grooves in one or both of upper section 802 and lower section 804 have differing groove patterns than the main section of vent grooves 800. Vent grooves 800 may be patterned on recess 302, for example, by injection molding a polymeric foam into a base component 102 or support layer 705 form having vent grooves 800 included in the injection form.

[0062] Base component 102 includes a bull nose 810 section of the padding layer 716 in some embodiments. Bull nose 810 may be constructed of the same material as padding layer 716 and may improve durability by having more of the knee end 740 surface being the material of padding layer 716 rather than the material of the support layer 705. Bull nose 810 also helps to properly orient and align padding layer 716 when being coupled to support layer 705. For example, the hook-and-loop fasteners 1010 and 1020 of FIG. 10A can be aligned and positioned if padding layer 716 includes a bull nose 810 as shown in FIGS. 8, 9A, and 9B.

[0063] FIGS. 9A and 9B depict a profile and plan view of non-limiting embodiments of kneeling support device 100. Vent grooves 800 in some or all sections may extend to the medial and lateral edges of base component 102. For example, FIGS. 9A and 9B show the central portion of vent grooves 800 extending all the way from the lateral edge to the medial edge of the support layer 705. In contrast, the vent grooves 800 shown in FIGS. 8 and 10A extend less far and are contained within the recess 302. Vent grooves 800 can vary in length, pattern, depth, and proximity to achieve improved ventilation and heat control during use.

[0064] FIGS. 10A and 10B illustrate non-limiting embodiments of kneeling support device 100. Padding layer 716 can removably couple to support layer 705 using a variety of different coupling or fastening mechanisms (e.g., compression fittings, hook-and-loop, snaps, plugs, clasps, and so forth). For example, hook layer 1010 can couple with loop layer 1020 to form a releasably coupled connection between padding layer 716 and support layer 705.

[0065] Structural support cavities 772 for housing structural support member(s) 770 can be embedded in support layer 705 as depicted in FIG. 7B, but they can be placed elsewhere as well. For example, structural support cavities 772 can be accessible from the knee end 740 as shown in FIG. 10A, which can allow structural support member(s) 770 to be replaced from the outside of base component 102. Structural support cavities 1030 located in padding layer 716 can supplement or can be used instead of structural support cavities 772.

[0066] In numerous embodiments, the base component102 varies in thickness along the recess 302. The thickness below the knee 106 may be less than the thickness near above the apex of the cutout 122, causing the recess 302 to slope upwards. The thickness of base component 102 above the apex of cutout 122 may be 1.5 to 6 times thicker than the thickness of base component 102 below the knee 106 (e.g., 1.5-3 times thicker, 2-3 times thicker, 2-5 times thicker, and so forth). The user 112 feels less pressure and discomfort as the recess 302 slopes upwards, the foot is provided more room, and the padding layer 116 / 716 engages fully with the floor.

[0067] Kneeling support device 100 is sized and shaped to fit the leg 104 of user 112. The width of base component 102 can be: 3.5″-9″, 3″-10″, 5″-8″, 5.5″-6.5″, and other widths that cover the leg 104 without impeding the user's 112 ability to walk. The length of base component 102 can be: 14″-27″, 12″-36″, 18″-25″, 20″-26″, 20″-28″, 21″-23″, 21″-25″, or other lengths that cover the leg 104 without impeding the user's 112 ability to walk. In various embodiments, the kneeling support device is sufficiently long and rigid to span joists spaced apart (e.g., 12″ on center, 16″ on center, or 24″ on center).

[0068] FIGS. 11A-11C depict various views of non-limiting embodiments of bridge assembly 1100. Kneeling support device 100 operates together with bridge assembly 1100 and functions as a kneeling support system. The disclosed kneeling support system is not limited to including only the kneeling support device 100 operating together with the bridge assembly 1100. Bridge assembly 1100 fits onto joists, dimensional lumber, engineered wood, engineered “I” joists, or other features, thereby allowing user 112 to kneel with kneeling support device 100 on the bridge assembly 1100 in addition to the nearby joists or features. Bridge assembly 1100 includes a bridge span 1130 coupled to and between a first bracket 1110 and a second bracket 1120. Bridge span 1130 includes an adjuster 1132, which can be any of a variety of adjusters to allow tubular or U-shaped metal to slidingly adjust and lock in place. Adjuster 1132 may be a bolt assembly, a pin, a wingnut and bolt, a lever, or any of numerous locking adjusting mechanisms.

[0069] First bracket 1110 and second bracket 1120 are sized and shaped to fit over and onto joists 1190. Joists 1190 can be any among a wide variety of joists including dimensional lumber, engineered wood, engineered “I” joists, and so forth. In some embodiments, first bracket 1110 and second bracket 1120 are sized and shaped to fit over and onto joists 1190 that are 1.5″ edges of dimensional lumber or other wood. Wedge aligners 140 operate to compressively fit onto joists 1190 and help align each of first and second brackets 1110 and 1120 to reduce movement of bridge assembly 1100 during use. A plurality of wedge aligners 1140 may be employed, for example, having at least two wedge aligners 1140 per side and may be spaced in an alternating fashion as shown in FIG. 11C. The flush gap 1150 is the minimum distance between opposing wedge aligners 1140 and where a joist 1190 will sit flush against the top of the bracket 1110 / 1120. Flush gap 1150 may be 1.5″ and offer no compression of wood for joist 1190. If the flush gap 1150 is 1.3″, then a 1.5″ joist 1190 will be compressed approximately 0.1″ on each side at each wedge aligner 1140. Brackets 1110 / 1120 are difficult to pull off of joist 1190 if wedge aligners 1140 compress joists 1190 a significant percentage, so flush gap 1150 is designed to compress up to 10%, up to 15%, up to 20%, up to 30%, or up to 40% depending on the wood and the embodiment. Mouth gap 1152 is wider than flush gap 1150 and the angle of wedge aligners is determined by the measurements for the wedge length 1154, mouth gap 1152, and flush gap 1150.

[0070] Bridge assembly 1100 may be constructed primarily of metal, polymer, or composite materials. Bridge assembly 1100 is primarily an aluminum alloy constructed of U-shaped or similar structural components. An aluminum alloy bridge assembly 1100 can be cast aluminum, machined aluminum, or a combination of the two. In some embodiments, wedge aligners 1140 increase the structural integrity of brackets 1110 / 1120 by operating as buttresses that limit deflection of the U-shaped brackets 1110 / 1120 while under weight or experiencing other forces. The bridge assembly 1100 has sufficient strength to bear the weight of the user 112 and some work tools or materials. The bridge assembly 1100 can have a load-bearing capacity of at least: 150 lbs, 250 lbs, 300 lbs, 350 lbs, 400 lbs, 450 lbs, and so forth. The bridge assembly 1100 can come in different load-bearing capacities, for example, a light weight version of bridge assembly 1100 with a lower load-bearing capacity than a heavier version of bridge assembly 1100.

[0071] User 112 positions bridge assembly 1100 on joists 1190, which allows user 112 to utilize joists 1190 and the orthogonal bridge span 1130 to kneel on with kneeling support device 100. Having bridge assembly 1100 provides a more comfortable and safer working environment for user 112 while kneeling on joists 1190 with kneeling support device 100. Having access to an orthogonally positioned bridge span 1130 reduces the odds of user 112 losing balance and punching a hole into the ceiling sheetrock attached to the bottom of joist 1190.

[0072] FIGS. 12-15 depict various views of non-limiting embodiments of joist platform system 1200. Joist platform system 1200 includes one or more platform assemblies 1202 and, in numerous embodiments, further includes platform caddy 1400 configured to hold and carry multiple platform assemblies 1202 together as a portable system. Joist platform system 1200 may be used by itself or together with one kneeling support device 100 or a pair of kneeling support devices 100, including embodiments in which one kneeling support device 100 is worn on each leg of a user. In numerous embodiments, each kneeling support device 100 is sized and shaped to be worn on a leg of the user and extends from a knee region of the user to a location above an ankle region of the user. Joist platform system 1200 may be particularly useful while a user moves or works generally parallel to joists 1290, where kneeling support device 100 may span adjacent joists 1290 but may still benefit from additional support area beneath the user. Joist platform system 1200 may be used to create a temporary travel path, to increase available support area in a selected work region, or both. Each platform assembly 1202 may be independently positioned on a single joist 1290 or other framing member without requiring connection to a second joist or a bridging structure, which can be beneficial in attics and other confined spaces having pipes, wires, ducting, framing irregularities, blown insulation, or other obstacles that make larger support members inconvenient or impractical. Joist platform system 1200 may therefore reduce reliance on plywood sheets, larger bridge structures, or cut-to-fit supports while still providing localized support where needed. In other embodiments, joist platform system 1200 may be used together with bridge assembly 1100 where desired, although joist platform system 1200 may also serve as a primary alternative to bridge assembly 1100 in numerous use cases.

[0073] Each platform assembly 1202 includes platform 1204 positioned above a saddle 1206. Platform 1204 provides an upper support surface for a hand, knee (e.g., with or without pads), elbow, foot, tool, attachment 1600, kneeling support device 100, another type of kneepad, or another supported item during use. In numerous embodiments, platform 1204 is sized and shaped to support at least a portion of kneeling support device 100 while kneeling support device 100 is worn by the user and while platform assembly 1202 is coupled to joist 1290 or another framing member. In numerous embodiments, platform 1204 is sized and shaped to support kneeling support device 100 while kneeling support device 100 spans joists 1290 spaced about 12 inches on center, about 16 inches on center, or about 24 inches on center. In one embodiment, platform 1204 has a generally circular, generally flat, disc-like shape with a diameter of about 6 inches and platform assembly 1202 has an overall height of about 2 inches. In other embodiments, platform 1204 may have a smaller or larger diameter, for example, about 4 inches, about 5 inches, about 6 inches, about 8 inches, about 10 inches, about 10.5 inches, about 12 inches, about 14 inches, or another suitable diameter. In still other embodiments, the diameter of platform 1204 may fall within a selected range, for example, about 4 inches to about 11 inches, about 4 inches to about 10.5 inches, about 4 inches to about 6 inches, about 5 inches to about 7 inches, about 5 inches to about 8 inches, about 6 inches to about 10 inches, or about 8 inches to about 13 inches. Platform 1204 may have a circular, hexagonal, octagonal, rounded polygonal, or other suitable outer shape. The upper surface of platform 1204 may be generally flat, slightly textured, provided with an anti-slip surface treatment, or provided with indicia such as a logo or other marking. In certain embodiments, platform 1204 includes a chamfered peripheral edge to provide smoother engagement with kneeling support device 100 and reduce abrasive wear during repeated use, such as a chamfered edge 1500 shown in FIG. 15. In other embodiments, platform 1204 may include a rounded edge, a squared edge, or another edge profile according to desired comfort, molding, or wear characteristics.

[0074] In numerous embodiments, platform assembly 1202 has an overall height of about 2 inches. In other embodiments, platform assembly 1202 may have an overall height that is smaller or larger, for example, about 1.5 inches to about 3 inches, about 1.75 inches to about 3 inches, about 2 inches to about 3 inches, or another suitable height selected according to desired engagement with joist 1290, desired bite by teeth 1210, desired molding characteristics, or desired support characteristics. Saddle 1206 is positioned below platform 1204 and defines channel 1208 configured to receive an upper portion of joist 1290 or another framing member. As used herein, a framing member may include joists 1290, dimensional lumber, engineered wood, engineered I-joists, rafters, truss members, and other structural members having an upper edge or upper surface receivable within channel 1208. In numerous embodiments, saddle 1206 and channel 1208 are sized and shaped to seat onto nominal 2× lumber, for example, lumber having an actual width near 1.5 inches. In other embodiments, saddle 1206 and channel 1208 may have greater or lesser spacing to accommodate dimensional variations, engineered wood products, older homes having thicker joists, or other framing conditions. Channel 1208 may have a depth of at least about 1.75 inches in numerous embodiments. In other embodiments, channel 1208 may be deeper or shallower, for example, about 1.5 inches to about 2 inches, about 1.75 inches to about 2.5 inches, or about 2 inches to about 3 inches. When seated on joist 1290, platform assembly 1202 creates a stable support surface on a single joist 1290 such that no second joist and no plywood bridge are required. In numerous embodiments, that single-joist configuration can be beneficial where obstacles prevent a user from conveniently positioning a larger sheet or bridge structure across multiple joists 1290. In numerous embodiments, a user deploys a plurality of platform assemblies 1202 (e.g., four platform assemblies 1202 from a kit) across two or more joists 1290, framing members, or the like.

[0075] Teeth 1210 are located on the inside of channel 1208 and removably couple platform assembly 1202 to joist 1290. In numerous embodiments, teeth 1210 comprise alternating sets of guide teeth 1212 and compression teeth 1214 located on opposite inner portions of channel 1208. In certain embodiments, guide teeth 1212 have generally straight-triangular profiles and compression teeth 1214 have generally ascending-triangular profiles. Guide teeth 1212 and compression teeth 1214 may be discrete teeth, segmented teeth, ridge-like teeth, or other tooth forms while remaining guide teeth 1212 and compression teeth 1214. In one current embodiment, teeth 1210 include four sets of guide teeth 1212 and three sets of compression teeth 1214 arranged in alternating order along channel 1208, although greater or fewer numbers of guide teeth 1212 and compression teeth 1214 are contemplated. For example, channel 1208 may include two sets of guide teeth 1212 and one set of compression teeth 1214, three sets of guide teeth 1212 and two sets of compression teeth 1214, four sets of guide teeth 1212 and three sets of compression teeth 1214, five sets of guide teeth 1212 and four sets of compression teeth 1214, or other suitable arrangements. Each guide tooth 1212 may be opposed by another guide tooth 1212 on the opposite side of channel 1208, and each compression tooth 1214 may be opposed by another compression tooth 1214 on the opposite side of channel 1208. During seating of saddle 1206 onto joist 1290, guide teeth 1212 and compression teeth 1214 may engage joist 1290 substantially together. Guide teeth 1212 help align and center saddle 1206 on joist 1290, while compression teeth 1214 contribute removable retention once platform assembly 1202 is pressed downward into the seated position. Guide teeth 1212 and compression teeth 1214 may be integrally molded with saddle 1206 in numerous embodiments, while in other embodiments guide teeth 1212 and compression teeth 1214 may be separately formed and then coupled to saddle 1206.

[0076] Compression teeth 1214 may taper inwardly from a wider spacing near the opening of channel 1208 to a narrower spacing nearer the upper portion of channel 1208 where joist 1290 approaches the underside of platform 1204. In numerous embodiments, compression teeth 1214 do not substantially bite into joist 1290 until an upper portion of compression teeth 1214 engages joist 1290. For example, the upper 10% to 20% of the length of each compression tooth 1214 may provide the primary bite into wood of joist 1290. In other embodiments, bite may occur over an upper 10% to 30% of the length of compression teeth 1214. The angled slope of the compression teeth 1214 determine where the joist 1290 begins to be compressed by the compression teeth 1214, so it is feasible that 90-100% of the height of compression teeth 1214 can engage with the joist 1290 when a shallow angle is employed. A steeper angle, conversely, may result in the compression teeth 1214 only engaging and biting into the joist 1290 at the topmost 5% of the length. Opposing compression teeth 1214 may collectively bite into joist 1290 by a total amount of about 1 / 16 inch to about ¼ inch, with about ⅛ inch total being suitable in one present embodiment. The retention force provided by guide teeth 1212 and compression teeth 1214 may be tuned by varying tooth angle, tooth spacing, tooth height, saddle 1206 flexibility, material stiffness, channel 1208 dimensions, or combinations thereof. In numerous embodiments, retention of platform assembly 1202 on joist 1290 results from a combination of bite by compression teeth 1214, wedging or interference fit, and elastic deformation of saddle 1206. In numerous embodiments, that coupling resists rotation about the joist axis, resists longitudinal sliding along joist 1290, resists side-to-side wobble, and still permits lift-off by hand when desired. Platform assembly 1202 may therefore be removably retained on joist 1290 in a manner that is secure during use yet releasable without tools.

[0077] Brace ribs 1220 extend between platform 1204 and saddle 1206 and increase the structural rigidity and load-bearing stability of platform assembly 1202. In one current embodiment, platform assembly 1202 includes four brace ribs 1220 arranged around saddle 1206. Brace ribs 1220 may resist downward bending of platform 1204, resist torsional deflection from off-center loading, maintain the width of channel 1208, reinforce sidewalls of saddle 1206, and transfer loads from platform 1204 into saddle 1206 and the received joist 1290. In other embodiments, brace ribs 1220 may have different forms while retaining the same canonical structure and function. For example, brace ribs 1220 may be hollow, apertured, ribbed, latticed, buttressed, wall-like, tapered, stepped, curved, or combinations thereof. In some embodiments, one or more brace ribs 1220 include one or more apertures to reduce weight or material while preserving desired reinforcement. In some embodiments, brace ribs 1220 have the same height as sidewalls of saddle 1206. In other embodiments, brace ribs 1220 may have different heights than sidewalls of saddle 1206, for example, to tune stiffness, reduce weight, alter molding flow, or change load transfer into saddle 1206. In other embodiments, platform assembly 1202 may include three brace ribs 1220, four brace ribs 1220, five brace ribs 1220, six brace ribs 1220, or another number of brace ribs 1220. In numerous embodiments, platform 1204, saddle 1206, channel 1208, teeth 1210, brace ribs 1220, and carry apertures 1230 are formed together in a one-piece molded structure.

[0078] Carry apertures 1230 are formed in platform 1204 and facilitate carrying, lifting, repositioning, removal, storage, orientation, tethering, or attachment of platform assembly 1202. In one current embodiment, platform 1204 includes two opposing carry apertures 1230 positioned for one-hand gripping by a user, for example, with a thumb and one or more fingers, to carry platform assembly 1202 or pull platform assembly 1202 upward off joist 1290. In other embodiments, platform 1204 may include three carry apertures 1230, four carry apertures 1230, or another number of carry apertures 1230, for example, between about 2 and about 4 carry apertures 1230. Carry apertures 1230 may be round, elongated, slotted, oval, polygonal, or otherwise shaped. Carry apertures 1230 may be positioned symmetrically, oppositely, radially, quadrantly, offset, or otherwise arranged according to ergonomics, lifting mechanics, molding considerations, alignment with attachment 1600, or desired orientation cues. In numerous embodiments, the location of carry apertures 1230 is selected not only for carrying comfort but also to facilitate outward flexing of saddle 1206 during lift-off. For example, a user may grasp platform assembly 1202 with one or two hands and apply upward force through opposing carry apertures 1230 to elastically expand saddle 1206 and reduce engagement of teeth 1210 (especially compression teeth 1214) with joist 1290, thereby making removal and lift-off easier. Carry apertures 1230 may therefore cooperate with the flexibility of saddle 1206 and the placement of teeth 1210 to permit secure removable retention during use and easier manual removal when desired. Carry apertures 1230 may also provide an orientation reference such that platform assembly 1202 can be grasped and placed quickly, including in dimly lit or insulated spaces where direct visual alignment may be difficult.

[0079] Platform assembly 1202 may be formed as a one-piece, molded, monolithic part in numerous embodiments. Injection-molded polymer embodiments are preferred for current commercial implementation. Suitable polymeric materials include nylon, polyamides, polypropylene, polyethylene, high-density polyethylene (HDPE), polycarbonate, acrylonitrile butadiene styrene (ABS), polyetherimide (PEI), polyoxymethylene (POM), acrylonitrile styrene acrylate (ASA), and glass-filled versions of one or more of those materials. Reinforced polymer embodiments are also contemplated, including polymers reinforced with glass fibers, carbon fibers, aramid fibers, mineral fillers, or other reinforcement materials. Additional embodiments may employ graphene-containing materials or other enhanced polymer formulations. Although polymeric construction is preferred in numerous embodiments, platform assembly 1202 may also be formed primarily of cast aluminum while still including carry apertures 1230, teeth 1210, and brace ribs 1220. Platform assembly 1202 may be manufactured by injection molding, casting, machining, additive manufacturing, thermoforming, compression molding, or other suitable techniques. The selected material and construction may provide sufficient strength and rigidity to support a user carrying tools or supplies while kneeling, crawling, shifting weight, or staging equipment on platform assembly 1202. In certain embodiments, platform assembly 1202 has sufficient flexibility such that upward lifting force applied through carry apertures 1230 elastically expands saddle 1206 and reduces engagement of teeth 1210 with joist 1290 to facilitate removal of platform assembly 1202 from joist 1290.

[0080] In some embodiments, platform assembly 1202 is glow-in-the-dark or otherwise includes one or more light-emissive or light-visible features to improve safety and locate platform assemblies 1202 in dark work environments. For example, platform assembly 1202 may be formed largely of a glow-in-the-dark material, coated with a glow material, or provided with one or more inserts, markings, or indicia having glow characteristics. Glow features may extend across substantially the entire platform assembly 1202 or may be limited to selected regions, such as platform 1204, carry apertures 1230, peripheral markings, logos, or other indicia. In other embodiments, glow features may be positioned adjacent carry apertures 1230 to facilitate location and removal of platform assembly 1202 in dark spaces. Such embodiments may help mark a safe path in an attic or other dark workspace and may also help a user locate an individual platform assembly 1202 after repositioning tools, disturbing insulation, or changing work position. In other embodiments, platform assembly 1202 may include reflective features, phosphorescent features, photoluminescent features, or combinations thereof.

[0081] Platform caddy 1400 may hold and carry multiple platform assemblies 1202 together as a compact kit. In one current embodiment, platform caddy 1400 is configured to hold four platform assemblies 1202 in a stacked arrangement and includes a carry handle 1410, base 1420, and retaining wall assembly 1430. The retaining wall assembly 1430 may include solid-wall sections 1432 connected by one or more bridges 1434 or other spanning member or wall section including one or more apertures. In some embodiments, a platform caddy 1400 configured to carry four platform assemblies 1202 can be sufficient for many crawling and working tasks while remaining compact enough for convenient transport into attics and other confined workspaces. Other quantities are also contemplated, however, including two, three, six, eight, twelve, sixteen, or other numbers of platform assemblies 1202. In certain embodiments, a user may carry multiple joist platform systems 1200 together. Platform caddy 1400 may hold platform assemblies 1202 in a stacked arrangement, nested arrangement, offset arrangement, divided arrangement, or another carrying arrangement. Platform caddy 1400 may retain platform assemblies 1202 by gravity, by partial enclosure, by a removable strap, by a cover, by a latch, by interlocking fit, or by another suitable holding arrangement. Platform caddy 1400 may include a carry handle 1410, side handle, strap, cover, latch, partial enclosure, or another retention feature while remaining platform caddy 1400. In one current dimensional example, platform caddy 1400 has a base 1420 portion of about 2 inches and receives four platform assemblies 1202 each having a height of about 2 inches to form a stack about 10 inches tall, although other caddy and stack dimensions are contemplated. Each platform assembly 1202 may be sized to be received in platform caddy 1400 in the stacked arrangement. Platform caddy 1400 may therefore hold and carry multiple platform assemblies 1202 together in a portable joist platform system 1200 kit. Platform caddy 1400 may include a double saddle 1422 on the base 1420 to allow for mounting onto joist 1290 in two different directions, as depicted in FIGS. 14A-14C (e.g., double saddle 1422 can mount on joist 1290 in two roughly orthogonal directions). The base of platform caddy 1400 may also employ a variation of saddle 1206 in other embodiments.

[0082] During use, a user may place one or more platform assemblies 1202 onto joists 1290 along a desired path of travel, for example, while entering an attic work area, moving parallel to joists 1290, or repositioning within a selected work region. In numerous embodiments, the user wears one kneeling support device 100 or a pair of kneeling support devices 100 while using platform assemblies 1202. Platform assemblies 1202 may be leapfrogged, spread across a work area, or both, depending on the task and available joists 1290. Once at a selected work location, the user may spread platform assemblies 1202 across the work area to increase available support area and reduce wobbly movements that may otherwise occur on narrow joist surfaces. Because platform assemblies 1202 engage individual joists 1290 and do not require bridging to another joist, platform assemblies 1202 may be particularly convenient where blown insulation, pipes, wires, ductwork, or framing obstacles limit the usefulness of plywood or larger bridging structures. Joist platform system 1200 may be used in attics, crawlspaces, unfinished basements, open framing, inspection environments, maintenance environments, and construction environments. Those features can be beneficial for insulators, electricians, heating, ventilation, and air conditioning technicians, plumbers, pest-control workers, and home inspectors, although joist platform system 1200 is not limited to those trades.

[0083] FIGS. 16A-16C depict non-limiting embodiments of attachment 1600 configured to cooperate with platform assembly 1202. Attachment 1600 includes attachment base 1620 configured to seat on top of platform 1204. In numerous embodiments, one or more orientation bosses 1630 protrude downward from attachment base 1620 and are received in carry apertures 1230 to orient attachment 1600 relative to platform assembly 1202 and reduce rotation or sliding between the parts. Attachment base 1620 may further include retaining skirt 1640 protruding downward and configured to engage an outer edge of platform 1204. Retaining skirt 1640 may be complete, partial, segmented, continuous, tapered, stepped, flexible, rigid, or combinations thereof while remaining retaining skirt 1640. Depending on the embodiment, attachment 1600 may sit on top of platform 1204, around platform 1204, or both. In numerous embodiments, attachment 1600 is retained on platform 1204 by gravity alone, by orientation bosses 1630, by retaining skirt 1640, or by combinations thereof. Orientation bosses 1630 may comprise one, two, three, four, or more projections and may have round, oval, polygonal, tapered, or other outer profiles. In numerous embodiments, the size and shape of orientation bosses 1630 correspond to the size and shape of carry apertures 1230 to provide desired alignment and fit. Attachment 1600 may include a handle 1610 or other member sized and shaped for carrying. The primary purpose of attachment 1600 may be to operate as a container, tray, tool holder, parts holder, cup, bin, instrument holder, fastener holder, or another work accessory. In some embodiments, attachment 1600 includes joist-engaging structure (e.g., similar to saddle 1206, double saddle 1422, a saddle including a channel or teeth, or the like) while in other embodiments attachment 1600 relies on platform 1204 for joist support.

[0084] FIGS. 17A and 17B depict non-limiting embodiments of attachment 1600 configured to be used in or with joist platform system 1200. Attachment 1600 may comprise a plumbing glue caddy as shown in FIGS. 17A and 17B. Attachment 1600 can be sized and shaped to house a variety of tools or materials a user would use to perform a task (e.g., tools, flashlight / lighting, repair components, building materials, fasteners, adhesives, personal items, a cellular phone, miscellaneous items, and so forth). In some embodiments, base 1620 comprises a double saddle 1422 instead of orientation bosses 1630 and / or retaining skirt 1640. Embodiments employing a double saddle 1422, saddle 1206, or other joist-mounting member are configured to mount on a joist 1290 or other support structure as described above. Here, the double saddle 1422 includes numerous teeth 1210 to secure the attachment 1600 onto joist 1290. Teeth 1210 may be guide teeth 1212, compression teeth 1214, or a combination of the two depending on how tight of a fit onto joist 1290 is desired. FIG. 17B depicts a double saddle 1422 design employing one compression tooth 1214 positioned between two guide teeth 1212.

[0085] FIGS. 18A-18C depict non-limiting embodiments of attachment 1600 configured to be used in or with joist platform system 1200. Here, attachment 1600 comprises a toolbox with multiple compartments. A double saddle 1422 can be sized and shaped differently based on the size and configuration of attachment 1600. A double saddle 1422 or other joist-mounting member can include teeth 1210, guide teeth 1212, compression teeth 1214, or other compression or mounting features. A toolbox attachment 1600 can mount on joist 1290 using a double saddle 1422 or a variety of different multi-saddles or other joist-mounting members. In some embodiments, toolbox attachment 1600 can mount onto platform assembly 1202 instead of directly mounting onto joist 1290. FIGS. 16A through 18C illustrate non-exclusive examples of attachment 1600 being capable of housing a wide variety of useful items normally carried in a tool belt, traditional toolbox, bucket, or other container. Attachment 1600 allows a user to conveniently access necessary tools and materials while reducing: lost items, damage to attic insulation, and tipping heavy items onto or through drywall ceilings. A tool bag can easily snag on adjacent attic features or dump out tools when a user is crawling and working with kneepads. The various disclosed embodiments of attachment 1600 reduce or eliminate the need for a user to carry a tool bag into attics and other awkward / confined spaces.

[0086] It should be understood that joist platform system 1200 is not limited to the specific configurations described above. Platform 1204, saddle 1206, channel 1208, teeth 1210, guide teeth 1212, compression teeth 1214, brace ribs 1220, carry apertures 1230, platform caddy 1400, handle 1410, base 1420, double saddle 1422, retaining wall assembly 1430, solid-wall sections 1432, bridge 1434, attachment 1600, handle 1610, attachment base 1620, orientation bosses 1630, and retaining skirt 1640 may each vary in number, shape, size, material, arrangement, and relative position according to desired performance characteristics. Different combinations of those features may be employed together with kneeling support device 100, bridge assembly 1100, or both.

RELATED APPLICATIONS

[0001] This application is a continuation-in-part of U.S. non-provisional patent application Ser. No. 19 / 317,014, filed Sep. 2, 2025, to Edward Schoen, titled “Kneeling Support Device and System,”, which is a continuation-in-part of U.S. non-provisional patent application Ser. No. 18 / 310,081, filed May 1, 2023, to Edward Schoen, titled “Kneeling Support Device,” and claims the benefit of U.S. provisional patent application 63 / 341,138, filed May 12, 2022 to Edward Schoen, titled “ToeKnee Crawler,” the entirety of the disclosures of which are hereby incorporated by this reference.TECHNICAL FIELD

[0002] This document relates to the field of kneeling support devices and systems. More specifically, the present disclosure relates to joist support platforms and a support cushion that easily attaches to the leg from the knees down to the foot. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present disclosure are also equally applicable to other like applications, devices, and methods of manufacture.BACKGROUND

[0003] By way of background, this disclosure relates to improvements in kneeling support devices. Generally, people who kneel for long periods of time throughout the day for work and other tasks may experience significant discomfort in the lower leg, ankle, and knee area. Further, blood flow restriction can cause pain to the feet and toes, resulting in a pins and needles type feeling in the extremities. Additionally, numbness can occur due to the increased lower leg pressure and may cause health issues if this process is repeated for several weeks and months at a time.

[0004] Typically, knee pads are widely used by landscapers, mechanics, plumbers, housekeepers, and other occupations requiring a kneeling position. Furthermore, existing kneeling devices which a user places on the ground to use, tend to shift around and slide. Further, prior art knee and shin pads can interfere with leg circulation when they are wrapped too tightly around the knee and / or shin. Further, some knee and shin pads are configured to be placed in pockets within the legs of pants. However, a user is limited to only that pair of pants.

[0005] Thus, there is a need for a kneeling support device that cushions and supports users who have to kneel for long periods of time throughout the day. Further, there is a need for a kneeling support that attaches to the user and does not slide around but is also not limited to one article of clothing.

[0006] There is also a need for devices that allow users to safely navigate across the top of joists in attics. Attics are confined spaces where improper placement of one's knee or leg can lead to punching a hole into the ceiling below.

[0007] Therefore, there exists a long-felt need in the art for a kneeling support device that provides users with a support cushion that easily attaches to the leg, from the knees down to the foot. There is also a long-felt need in the art for a kneeling support device that offers comfort and relief to the knees, lower leg area, toes and feet while in a kneeling position for extended periods of time. Further, there is a long-felt need in the art for a kneeling support device that can be used while carpet laying, roofing, plumbing, floor tiling or installation, etc. Moreover, there is a long-felt need in the art for a device that alleviates the pressure felt on other areas of the body due to shifting of a user's body weight for balance or a comfortable kneeling position. Further, there is a long-felt need in the art for a kneeling support device that features a lightweight, portable design that can be easily placed and secured on a user's leg and removed. Further, there is a long-felt need in the art for a kneeling support device that utilizes hook and loop fasteners to secure the device to a user's leg. Finally, there is a long-felt need in the art for devices that improve stability and reduce the likelihood of damaging the ceiling mounted to attic joists.SUMMARY

[0008] The following presents a simplified summary in order to provide a basic understanding of some aspects of this disclosure. This summary is not an extensive overview, and it is not intended to identify key / critical elements or to delineate the scope thereof. Its sole purpose is to present some general concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0009] According to one aspect, a kneeling support system for supporting a user on a framing member is described. The kneeling support system includes: a pair of kneeling support devices, each kneeling support device sized and shaped to be worn on a leg of the user and extending from a knee region of the user to a location above an ankle region of the user; and a plurality of platform assemblies, each platform assembly including: a platform; a saddle positioned below the platform; a channel defined by the saddle and sized and shaped to receive an upper portion of the framing member; a plurality of teeth located on an inside of the channel and configured to removably couple the platform assembly to the framing member; a plurality of brace ribs extending between the platform and the saddle; and at least two carry apertures formed in the platform; wherein the plurality of platform assemblies are manually positionable on respective framing members to provide additional support area for the user while the user traverses or works on the framing members.

[0010] In another aspect, in each platform assembly, the plurality of teeth comprise alternating sets of guide teeth and compression teeth, the guide teeth having a geometry that guides placement of the saddle on the framing member and the compression teeth having a tapered profile that removably retains the platform assembly on the framing member. In one aspect, the framing member is a joist, and wherein the compression teeth taper inwardly toward an upper portion of the channel such that an upper portion of each compression tooth bites into wood of the joist when the saddle is seated on the joist. In some aspects, the upper portion of each compression tooth comprises an upper 10% to 20% of a length of the compression tooth, and wherein opposing compression teeth collectively bite into the joist by a total amount of 1 / 16 inch to ¼ inch. In certain aspects. In one aspect, the platform of each platform assembly has a generally flat upper support surface and a diameter between 4 inches and 10.5 inches. In another aspect, the platform further comprises a textured upper support surface and a chamfered peripheral edge. In some aspects, the kneeling support system includes: a platform caddy having a geometry that holds and carries the plurality of platform assemblies together, the platform caddy including a carry handle.

[0011] According to another aspect, a framing member support assembly includes: a kneeling support device sized and shaped to be worn on a leg of a user and extending from a knee region of the user to a location above an ankle region of the user; and a platform assembly for removable placement on a framing member, the platform assembly including: a platform having an upper support surface configured to support at least a portion of the kneeling support device and the user's weight when in use; a saddle positioned below the platform; a channel defined by the saddle and configured to receive an upper portion of the framing member; a plurality of teeth disposed on opposed inner portions of the channel and configured to removably engage the framing member; a plurality of brace ribs extending between the platform and the saddle; and at least two carry apertures formed in the platform and configured to facilitate manual carrying and repositioning of the platform assembly.

[0012] In one aspect, the plurality of teeth comprise alternating sets of guide teeth and compression teeth, the guide teeth being disposed opposite one another within the channel and the compression teeth being disposed opposite one another within the channel. In another aspect, the channel has a depth of about 1.75 inches, and wherein each compression tooth is angled such that the compression tooth does not bite into the framing member until an upper portion of the compression tooth engages the framing member. In some aspects, the platform has a generally circular shape and a diameter of about 6 inches. In an aspect, the at least two carry apertures are disposed on opposite sides of the platform and are positioned to be gripped by one hand to lift and reposition the platform assembly. In another aspect, the platform assembly is formed primarily of a polymer material having sufficient flexibility such that upward lifting force applied through the at least two carry apertures elastically expands the saddle and reduces engagement of the teeth with the framing member to facilitate removal of the platform assembly from the framing member. In some aspects, the platform assembly is formed by injection molding, and wherein the kneeling support device is sufficiently long to span framing members spaced 16 inches on center.

[0013] According to one aspect, a framing member support kit includes: at least one kneeling support device sized and shaped to be worn on a leg of a user and extending from a knee region of the user to a location above an ankle region of the user; a plurality of platform assemblies, each platform assembly including: a platform; a saddle positioned below the platform; a channel defined by the saddle and sized and shaped to receive a framing member; a plurality of teeth located on an inside of the channel for removably coupling the platform assembly to the framing member; a plurality of brace ribs extending between the platform and the saddle; and at least two carry apertures formed in the platform; and a platform caddy configured to hold and carry the plurality of platform assemblies together, wherein the platform of each platform assembly is configured to support at least a portion of the kneeling support device and the platform assembly is coupled to the framing member.

[0014] According to some aspects, the platform caddy includes a carry handle and is configured to hold the plurality of platform assemblies in a stacked arrangement for transport. In one aspect, the plurality of platform assemblies comprises four platform assemblies. In some aspects, each platform assembly has a generally circular platform with a diameter of about 6 inches and an overall height of about 2 inches. In certain aspects, each platform assembly is sized to be received in the platform caddy in the stacked arrangement.

[0036] Detailed aspects and applications of the disclosure are described below in the following drawings and detailed description of the technology. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. In the drawings and detailed description, like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the disclosure can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the disclosure and do not limit the scope of the disclosure. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0037] As noted above, there is a long-felt need in the art for a kneeling support device that provides users with a support cushion that easily attaches to the leg, from the knees down to the foot. There is also a long-felt need in the art for a kneeling support device that offers comfort and relief to the knees, lower leg area, toes, and feet while in a kneeling position for extended periods of time. Further, there is a long-felt need in the art for a kneeling support device that can be used while carpet laying, roofing, plumbing, floor tiling or installation, etc. Moreover, there is a long-felt need in the art for a device that alleviates the pressure felt on other areas of the body due to shifting of a user's body weight for balance or a comfortable kneeling position. Further, there is a long-felt need in the art for a kneeling support device that features a lightweight, portable design that can be easily placed and secured on a user's leg and removed. Finally, there is a long-felt need in the art for a kneeling support device that utilizes hook and loop fasteners to secure the device to a user's leg.

[0038] The present disclosure, in one exemplary embodiment, is a novel kneeling support device. The device is an attachable, comfortable support device that may be applied to the leg of a user and extends from the knees down to the instep of the foot to help reduce the amount of pressure on the feet and toes of a user. The kneeling support device comprises a base component that is configured in a curved contour that wraps around the front of a user's leg and foot. The outer surface of the base component comprises at least one padding layer to cushion a user's knees and shins, while kneeling. The end of the base component near the foot comprises a cutout component that curves around a user's foot to provide comfort and support to the toes and feet while kneeling. Further, the base component comprises a large hook and loop fastener wrap that is secured around a user's calf for adhering the device to a user. The present disclosure also includes a novel method of supporting and cushioning a user's knees and shins. The method includes the steps of providing a kneeling support device comprising a base component that is configured to wrap around the front of a user's leg and foot. The method also comprises engaging the cutout component around a user's foot. Further, the method comprises positioning the base component around a user's shin and knee. Finally, the method comprises securing the device to a user's leg via hook and loop fasteners.

[0039] Referring initially to the drawings, FIG. 1 illustrates a perspective view of one embodiment of the kneeling support device 100 of the present disclosure. In the present embodiment, the kneeling support device 100 is an improved kneeling support device 100 that provides a user with comfort and support when kneeling for extended periods of time. Specifically, the device 100 is an attachable, comfortable support device 100 that may be applied to the leg 104 of a user 112 and extends from the knees 106 down to the instep of the foot 108 to help reduce the amount of pressure on the feet 108 and toes 110 of a user 112. The kneeling support device 100 comprises a base component 102 configured in a curved contour to the shape of a user's leg 104 and knee 106.

[0040] Further, the outer surface 114 of the base component 102 comprises at least one padding layer 116 to cushion a user's knees 106 and shins 118, while kneeling. The end 120 of the base component 102 near the foot 108 comprises a cutout component 122 that curves around a user's foot 108 to provide comfort and support to the toes 110 and feet 108 while kneeling. In use, the user 112 engages the cutout component 122 around the foot 108 before attaching the hook and loop fastener strap 124 around the calf area to its desired tightness. The device 100 rests on top 126 of the foot 108 and wraps tightly around each side 128 of the foot 108 to keep the device 100 in place. Accordingly, the kneeling support device 100 is then kept in place while in use. The cutout component 122 is sized and shaped to fit and engage the ankle near the talus bone of user 112 and near the top of foot 126. The cutout component 122 may have a generally arch-shaped topography. The cutout component 122 may have a span of 2″-6″, 3″-5″, 2.75″-5.5″, or 3″-4″, and have a rise of 1″-10″, 1″-8″, 1″-7″, 2″-6″, 4″-6″, or 3″-5″.

[0041] Generally, the kneeling support device 100 supports and cushions a user's knees 106 and legs 104 while kneeling for extended periods of time. Generally, the kneeling support device 100 comprises both a rigid knee shield 130 for covering a substantial part of a front surface of user's knee 106 and a rigid shin shield 132 for covering a substantial part of a user's shin 118. The rigid knee shield 130 and the rigid shin shield 132 can be separate components secured together in use or can be an integral one-piece component, depending on the needs and / or wants of a user. The kneeling support device 100 can be any suitable shape and size as is known in the art. Further, the kneeling support device 100 can be available in multiple sizes, depending on the height and / or size of a user's legs 104.

[0042] As shown in FIG. 2, the end 120 of the base component 102 near the foot 108 area comprises a cutout component 122 that curves around a user's foot 108 to provide comfort and support to the toes 110 and feet 108 while kneeling. In use, the cutout component 122 is engaged around a user's foot 108 before attaching the rest of the base component 102. Thus, once the device 100 is in position, the cutout component 122 rests on top 126 of the foot 108 and wraps tightly around each side 128 of the foot 108.

[0043] Further, the base component 102 comprises securing components 124 on either side. The securing components 124 act to secure the base component 102 around a user's leg 104 and knee 106. The securing components 124 include buttons, snaps, hook-and-loop fasteners, zippers, or other suitable fasteners operable to temporarily attach the base component 102 around a user's leg 104 and knee 106. In one embodiment, hook and loop fasteners 124 are used to secure the device 100 around a user's calf. In another embodiment, hook and loop fasteners 124 are used to secure the device 100 around a user's calf, knee 106, and ankle. Generally, any suitable number of hook and loop fasteners 124 can be utilized as is known in the art, depending on the needs and / or wants of a user.

[0044] Generally, the hook and loop fasteners 124 allow the user 112 to set a specific tightness to the device 100 around their leg 104. Thus, if another user 112 wears the device 100, or if the size of the user's leg 104 grows or increases, the length of the hook and loop fasteners 124 can be adjusted again via the hook and loop fasteners 124. Thus, the hook and loop fasteners 124 can be secured around a user's leg 104 to any desired tightness as is known in the art.

[0045] As shown in FIGS. 3-4, the device 100 comprises a base component 102 that is configured to contour to both a user's legs 104 and knees 106. Specifically, the base component 102 comprises an outer surface 114 and an inner surface 300. The inner surface 300 is configured in a curved contour that wraps partially around the front of a user's leg 104 and knee 106. Specifically, the curved contour of the base component 102 creates a recess 302 on the inner surface 300 of the base component 102, which contours to a user's leg 104. Recess 302 has a depth of at least 1″ (e.g., 1″+, 1.5″+, 2″+, 2.5″+, etc.) in various embodiments. The recess 302 runs the entirety of a portion of the length of the base component 102, for example, 100%, 70-100%, 55-85%, 65-75%, 30-80%, or 40-75% of the length from the apex of the cutout component 122 to the top end of the base component 102.

[0046] Furthermore, the outer surface 114 comprises multiple layers. Generally, the multiple layers comprise padding layers 116 and support and cushioning layers. In one embodiment, the outer surface 114 comprises a protective barrier layer 304. The multiple padding and cushioning layers 116 are flexible and conform to a user's knee 106 and leg 104. The protective barrier layer 304 is a hard plastic layer that is generally shaped to fit the outer-facing region of the knee 106 and shin 118. The protective barrier layer 304 is typically not flexible and may stay straight as a user 112 bends a knee 106. The protective barrier layer 304 may be detachable from the multiple padding and cushioning layers 116 and protects a user 112 from abrasions, scratches, and discomfort. Further, the multiple layers 116 can be flexible, resilient, and / or water-resistant, and may be made of natural or synthetic materials, such as foams, sponges, gels, or other compressible materials known to those of skill in the art.

[0047] In one embodiment, the optional protective barrier layer 304 can comprise a shell, a covering or a jacket placed over the layers 116 as necessary for field or work conditions. The protective barrier layer 304 can manufactured of various materials, such as polycarbonate, polyethylene, PVC, ABS, etc., or other hard plastic materials known to those skilled in the art. The protective barrier layer 304 can be any suitable color or design depending on the use of the device 100 and can even be camouflaged for hunters, such as green camouflage for bush or field hunting or brownish / grayish for duck hunting.

[0048] Additionally, extra padding and / or layers can be added to selected portions of the base component 102, such as around the knee 106 as desired. Further, while the aforesaid device 100 is designed for use in work or field conditions, it is also noted that the device 100 may be used domestically in a house or apartment for users 112 who have knee conditions which require padding during normal household chores, such as cleaning floors or gardening.

[0049] As shown in FIG. 5, the kneeling support device 100 is secured over a garment 500, such as overall pants, leggings, work pants, etc., or other types of garments 500. Further, a user 112 may also wish to use the device 100 while wearing shorts or a short skirt, for example. Here, the kneeling support device 100 can be secured directly around a user's legs 104 and knees 106.

[0050] Generally, the kneeling support device 100 may be used in a variety of applications. For example, the kneeling support device 100 may shield and protect a user 112 while they are kneeling on a hard surface and installing new carpeting, landscaping, roofing, etc., or while standing on a ladder and leaning their knees 106 and shins 118 on the ladder.

[0051] In yet another embodiment, the kneeling support device 100 comprises a plurality of indicia 502. The base component 102 of the device 100 may include advertising, trademark, other letters, designs, or characters, printed, painted, stamped, or integrated into the base component 102, or any other indicia 502 as is known in the art. Specifically, any suitable indicia 502 as is known in the art can be included, such as, but not limited to, patterns, logos, emblems, images, symbols, designs, letters, words, characters, animals, advertisements, brands, etc., that may or may not be knee, support, cushion, or brand related.

[0052] FIG. 6 illustrates a flowchart of the method of supporting and cushioning a user's knees and shins. The method includes the steps of at 600, providing a kneeling support device comprising a base component that is configured to wrap around the front of a user's leg and foot. The method also comprises at 602, engaging the cutout component around a user's foot. Further, the method comprises at 604, positioning the base component around a user's shin and knee. Finally, the method comprises at 606, securing the device to a user's leg via hook and loop fasteners.

[0053] FIGS. 7A, 7B, 8, 9A, and 9B depict various views of non-limiting embodiments of kneeling support device 100. Base component 102 of kneeling support device 100 includes a padding layer 716 coupled to a support layer 705 (padding layer 116 discussed herein shares all or some of the features of padding layer 716, and vice versa, according to various different embodiments). In some embodiments, padding layer 716 is releasably coupled to support layer 705 or other elements of base component 102 (e.g., using hook and loop fasteners, compression fittings, or other releasable fastening devices). When a user 112 wears kneeling support device 100, the user's knee 106 is positioned near the knee end 740 and their ankle is located in or below cutout 122 at base end 120. Base component 102 may be constructed primarily of a foam polymer. In some embodiments, one or both of support layer 705 and padding layer 716 are primarily constructed of a closed-cell foam, an open cell foam, gel foam, memory foam, or other material providing compression capabilities. One or both of support layer 705 and padding layer 716 may be partially or fully constructed using closed-cell polyethylene foam. Padding layer 716 may have a higher density or higher rigidity than support layer 705, for example, a closed-cell polyethylene foam of padding layer 716 is 1.1-3.5 times, 2-6 times, 5-10 times, 8-25 times, 1.1-9.5 times, or 1.1-25 times denser than a closed-cell polyethylene foam of support layer 705 (different foams or different materials may have different ranges and ratios of density). Both the support layer 705 and padding layer 716 may be substantially constructed using closed-cell polyethylene foam where padding layer 716 has a higher density than support layer 705. Many elements of base component may be constructed of injection molded foam, machined or cut foam, or other methods of shaping foam parts. The density of support layer 705 provides structure for the base component 102, proper leg 104 fitment to improve operability during use, and physical comfort as the recess 302 conforms or fits the user's leg 104 during use (see FIGS. 2 and 8). The density of padding layer 716 offers a tough surface that can endure abuse during rugged construction conditions, increases the rigidity of base component 102, and provides a uniform surface engaging the floor and distributing the user's 112 weight more evenly.

[0054] Grip member 750 is located on the outer surface 114 or underside of base component 102. For example, when base component 102 includes a padding layer 716, grip member 750 is located on the underside of padding layer 716 to provide increased grip of objects located below user 112 when kneeling (e.g., joist 850 shown in FIG. 8). Grip member 750 may have a generally concave shape. Grip member 750 may be sized and shaped to fit a particular intended object, for example, the 1.5″ edge of dimensional lumber, engineered wood or joists, engineered “I” joists, and so forth (see FIG. 8 depicting a joist 850). For example, grip member 750 may be wider than a 1.5″ dimensional lumber edge to allow the grip member 750 to better engage a joist 850 of dimensional lumber and reduce the odds the user 112 will slip off the joist 850. As another example, grip member 750 is over 2.5″ wide, which can accommodate joists 850 made from 2× dimensional lumber and numerous engineered “I” joists, but not larger 4×_dimensional lumber and larger engineered “I” joists (e.g., 3.5″ wide joist tops).

[0055] The grip member 750 may be constructed of a durable and semi-rigid material that is also flexible and conformal (e.g., a foam, polymer, closed-cell foam, etc.) to help grip member 750 engage the object below and reduce slippage. Grip member 750 may have a textured surface, a contoured surface, a concave shape, or other gripping feature. Grip member 750 may be constructed of multiple layers and be constructed of the same or different materials than base component 102, support layer 705, or padding layer 716. In some embodiments, padding layer 716 is thicker than padding layer 116 to retain sufficient thickness due to reduced thickness at the thinnest portion of a concave grip member 750.

[0056] Grip member 750 is located at least at the upper end to allow gripping pressure to increase beneath the weight under knee 106 of user 112. Grip member 750 may be located within the first 4″ to 8″ of the knee end 740, for example, near padding knee end 742 located on padding layer 716 or near support layer knee end 744 if base component 102 has a unibody construction or otherwise omits or incorporates padding layer 716 into support layer 705. Grip member 750 may be positioned with knee placement 752 situated directly below knee 106 during use with drip member 750 extending above and below knee placement 752 by several inches (e.g., 1″, 2″, 3″, 4″, 5″, 6″, and so forth). In some embodiments, grip member 750 runs up to one quarter, one half, three-quarters, or the full distance from the knee end 740 (e.g., padding knee end 742 or support layer knee end 744) to the base end 120 or padding ankle end 720.

[0057] During use, the knee 106 of user 112 is positioned in recess 302 to be directly over the knee placement 752. Knee placement 752 is positioned to direct the pressure from knee 106 onto the object below (e.g., a joist) and increase the conformal grip of grip member 750 on the object. In some embodiments, the base component 102 and recess 302 are sized and shaped so the knee 106 is positioned above the knee placement 752. Grip member 750 may be sized and shaped in conjunction with recess 302 and cutout 122 to guide user 112 in proper knee 106 placement over grip member's 750 knee placement 752 by engaging cutout 122 into the ankle of user 112 near the talus bone (e.g., top of foot 126 area) and bringing the recess 302 to engage with the leg 104 and shin 118, thereby placing the knee 106 in line with knee placement 752 and allowing straps 760 to secure base component 102 in the correct position on the leg 104.

[0058] Kneeling support device 100 includes a flashlight 790 coupled to base component 102 in certain embodiments. Flashlight 790 can be an off-the-shelf flashlight, a custom flashlight, or another light source. Flashlight cavity 792 is a cavity deep enough to securely hold flashlight 790 in place during normal use (e.g., compression fit) but also allow for the removal of flashlight 790 to replace batteries, recharge, and so forth. Flashlight fastener 794 may be added to help secure flashlight 790 in the flashlight cavity 792. Flashlight fastener 794 can be an among a variety of fasteners, including hook-and-loop fasteners, clasp(s), latch(es), and so forth.

[0059] Kneeling support device 100 includes at least one structural support member 770 in various embodiments. Structural support member(s) 770 operate to increase strength and rigidity of the base component 102. If base component 102 is too flexible, the kneeling support device 100 will bend or contort when spanning a distance (e.g., bridging the distance between joists), applying most of the load near the middle or shin 118 area, or other use cases. Structural support member(s) 770 are constructed of strong and rigid materials like thermoset polymers, thermoplastic polymers, metal, polymers, fiber-reinforced polymers, and so forth. In some embodiments, structural support member(s) 770 are tubular rods of fiberglass or another fiber-reinforced polymer. Many different shapes and sizes of structural support member(s) 770 will increase rigidity and performance, and many different placement locations are contemplated herein. While FIG. 7B shows structural support member(s) 770 embedded inside support layer 705 in structural support cavity 772, the structural support member(s) 770 can be located elsewhere on, around, or inside kneeling support device 100 to provide sufficient increases in rigidity. Structural support member(s) 770 run generally parallel to the long axis of base component 102 in numerous embodiments.

[0060] Akin to the discussion of strap 124 elsewhere herein, kneeling support 100 includes at least one strap 760 to secure the base component 102 to the leg 104. For example, an upper strap 760A passes via feed through pair 762A while a lower strap 760B passes via feed through pair 762B, thereby allowing straps 760 (i.e., 760A &760B) to secure around leg 104 for use. Each strap 760 has a first end 765 and a second end 766 that fastens to first end 765. For example, first end 765 and second end 766 may include hook-and-loop fasteners (e.g., where second end 766 includes a longer section of loops than hooks on first end 765 to make straps 760 adjustable around different leg 104 diameters). Access ports 764 (e.g., upper access port 764A and lower access port 764B) allow user 112 to thread or unthread straps 760 in or out of feed through pairs 762 while padding layer 716 remains coupled in place to support layer 705. The access ports 764 allow for replacement of damaged straps 760 or installment of different sizes or types of straps 760.

[0061] FIG. 8 illustrates non-limiting embodiments of kneeling support device 100 positioned on a joist 850 as discussed above. Base component 102 includes vent grooves 800 according to various embodiments. Vent grooves 800 may include an upper section 802 and lower section 804. Vent grooves 800 include a plurality of grooves or contours encouraging air flow and ventilation to draw heat and sweat away from leg 104. The plurality of grooves of vent grooves 800 may be substantially parallel to each other or may intersect each other. For example, the plurality of grooves of vent grooves 800 may intersect each other generally orthogonally at right angles or intersect each other at any angle between 1° and 180°. In some embodiments, the pattern of intersecting grooves in one or both of upper section 802 and lower section 804 have differing groove patterns than the main section of vent grooves 800. Vent grooves 800 may be patterned on recess 302, for example, by injection molding a polymeric foam into a base component 102 or support layer 705 form having vent grooves 800 included in the injection form.

[0062] Base component 102 includes a bull nose 810 section of the padding layer 716 in some embodiments. Bull nose 810 may be constructed of the same material as padding layer 716 and may improve durability by having more of the knee end 740 surface being the material of padding layer 716 rather than the material of the support layer 705. Bull nose 810 also helps to properly orient and align padding layer 716 when being coupled to support layer 705. For example, the hook-and-loop fasteners 1010 and 1020 of FIG. 10A can be aligned and positioned if padding layer 716 includes a bull nose 810 as shown in FIGS. 8, 9A, and 9B.

[0063] FIGS. 9A and 9B depict a profile and plan view of non-limiting embodiments of kneeling support device 100. Vent grooves 800 in some or all sections may extend to the medial and lateral edges of base component 102. For example, FIGS. 9A and 9B show the central portion of vent grooves 800 extending all the way from the lateral edge to the medial edge of the support layer 705. In contrast, the vent grooves 800 shown in FIGS. 8 and 10A extend less far and are contained within the recess 302. Vent grooves 800 can vary in length, pattern, depth, and proximity to achieve improved ventilation and heat control during use.

[0064] FIGS. 10A and 10B illustrate non-limiting embodiments of kneeling support device 100. Padding layer 716 can removably couple to support layer 705 using a variety of different coupling or fastening mechanisms (e.g., compression fittings, hook-and-loop, snaps, plugs, clasps, and so forth). For example, hook layer 1010 can couple with loop layer 1020 to form a releasably coupled connection between padding layer 716 and support layer 705.

[0065] Structural support cavities 772 for housing structural support member(s) 770 can be embedded in support layer 705 as depicted in FIG. 7B, but they can be placed elsewhere as well. For example, structural support cavities 772 can be accessible from the knee end 740 as shown in FIG. 10A, which can allow structural support member(s) 770 to be replaced from the outside of base component 102. Structural support cavities 1030 located in padding layer 716 can supplement or can be used instead of structural support cavities 772.

[0066] In numerous embodiments, the base component102 varies in thickness along the recess 302. The thickness below the knee 106 may be less than the thickness near above the apex of the cutout 122, causing the recess 302 to slope upwards. The thickness of base component 102 above the apex of cutout 122 may be 1.5 to 6 times thicker than the thickness of base component 102 below the knee 106 (e.g., 1.5-3 times thicker, 2-3 times thicker, 2-5 times thicker, and so forth). The user 112 feels less pressure and discomfort as the recess 302 slopes upwards, the foot is provided more room, and the padding layer 116 / 716 engages fully with the floor.

[0067] Kneeling support device 100 is sized and shaped to fit the leg 104 of user 112. The width of base component 102 can be: 3.5″-9″, 3″-10″, 5″-8″, 5.5″-6.5″, and other widths that cover the leg 104 without impeding the user's 112 ability to walk. The length of base component 102 can be: 14″-27″, 12″-36″, 18″-25″, 20″-26″, 20″-28″, 21″-23″, 21″-25″, or other lengths that cover the leg 104 without impeding the user's 112 ability to walk. In various embodiments, the kneeling support device is sufficiently long and rigid to span joists spaced apart (e.g., 12″ on center, 16″ on center, or 24″ on center).

[0068] FIGS. 11A-11C depict various views of non-limiting embodiments of bridge assembly 1100. Kneeling support device 100 operates together with bridge assembly 1100 and functions as a kneeling support system. The disclosed kneeling support system is not limited to including only the kneeling support device 100 operating together with the bridge assembly 1100. Bridge assembly 1100 fits onto joists, dimensional lumber, engineered wood, engineered “I” joists, or other features, thereby allowing user 112 to kneel with kneeling support device 100 on the bridge assembly 1100 in addition to the nearby joists or features. Bridge assembly 1100 includes a bridge span 1130 coupled to and between a first bracket 1110 and a second bracket 1120. Bridge span 1130 includes an adjuster 1132, which can be any of a variety of adjusters to allow tubular or U-shaped metal to slidingly adjust and lock in place. Adjuster 1132 may be a bolt assembly, a pin, a wingnut and bolt, a lever, or any of numerous locking adjusting mechanisms.

[0069] First bracket 1110 and second bracket 1120 are sized and shaped to fit over and onto joists 1190. Joists 1190 can be any among a wide variety of joists including dimensional lumber, engineered wood, engineered “I” joists, and so forth. In some embodiments, first bracket 1110 and second bracket 1120 are sized and shaped to fit over and onto joists 1190 that are 1.5″ edges of dimensional lumber or other wood. Wedge aligners 140 operate to compressively fit onto joists 1190 and help align each of first and second brackets 1110 and 1120 to reduce movement of bridge assembly 1100 during use. A plurality of wedge aligners 1140 may be employed, for example, having at least two wedge aligners 1140 per side and may be spaced in an alternating fashion as shown in FIG. 11C. The flush gap 1150 is the minimum distance between opposing wedge aligners 1140 and where a joist 1190 will sit flush against the top of the bracket 1110 / 1120. Flush gap 1150 may be 1.5″ and offer no compression of wood for joist 1190. If the flush gap 1150 is 1.3″, then a 1.5″ joist 1190 will be compressed approximately 0.1″ on each side at each wedge aligner 1140. Brackets 1110 / 1120 are difficult to pull off of joist 1190 if wedge aligners 1140 compress joists 1190 a significant percentage, so flush gap 1150 is designed to compress up to 10%, up to 15%, up to 20%, up to 30%, or up to 40% depending on the wood and the embodiment. Mouth gap 1152 is wider than flush gap 1150 and the angle of wedge aligners is determined by the measurements for the wedge length 1154, mouth gap 1152, and flush gap 1150.

[0070] Bridge assembly 1100 may be constructed primarily of metal, polymer, or composite materials. Bridge assembly 1100 is primarily an aluminum alloy constructed of U-shaped or similar structural components. An aluminum alloy bridge assembly 1100 can be cast aluminum, machined aluminum, or a combination of the two. In some embodiments, wedge aligners 1140 increase the structural integrity of brackets 1110 / 1120 by operating as buttresses that limit deflection of the U-shaped brackets 1110 / 1120 while under weight or experiencing other forces. The bridge assembly 1100 has sufficient strength to bear the weight of the user 112 and some work tools or materials. The bridge assembly 1100 can have a load-bearing capacity of at least: 150 lbs, 250 lbs, 300 lbs, 350 lbs, 400 lbs, 450 lbs, and so forth. The bridge assembly 1100 can come in different load-bearing capacities, for example, a light weight version of bridge assembly 1100 with a lower load-bearing capacity than a heavier version of bridge assembly 1100.

[0071] User 112 positions bridge assembly 1100 on joists 1190, which allows user 112 to utilize joists 1190 and the orthogonal bridge span 1130 to kneel on with kneeling support device 100. Having bridge assembly 1100 provides a more comfortable and safer working environment for user 112 while kneeling on joists 1190 with kneeling support device 100. Having access to an orthogonally positioned bridge span 1130 reduces the odds of user 112 losing balance and punching a hole into the ceiling sheetrock attached to the bottom of joist 1190.

[0072] FIGS. 12-15 depict various views of non-limiting embodiments of joist platform system 1200. Joist platform system 1200 includes one or more platform assemblies 1202 and, in numerous embodiments, further includes platform caddy 1400 configured to hold and carry multiple platform assemblies 1202 together as a portable system. Joist platform system 1200 may be used by itself or together with one kneeling support device 100 or a pair of kneeling support devices 100, including embodiments in which one kneeling support device 100 is worn on each leg of a user. In numerous embodiments, each kneeling support device 100 is sized and shaped to be worn on a leg of the user and extends from a knee region of the user to a location above an ankle region of the user. Joist platform system 1200 may be particularly useful while a user moves or works generally parallel to joists 1290, where kneeling support device 100 may span adjacent joists 1290 but may still benefit from additional support area beneath the user. Joist platform system 1200 may be used to create a temporary travel path, to increase available support area in a selected work region, or both. Each platform assembly 1202 may be independently positioned on a single joist 1290 or other framing member without requiring connection to a second joist or a bridging structure, which can be beneficial in attics and other confined spaces having pipes, wires, ducting, framing irregularities, blown insulation, or other obstacles that make larger support members inconvenient or impractical. Joist platform system 1200 may therefore reduce reliance on plywood sheets, larger bridge structures, or cut-to-fit supports while still providing localized support where needed. In other embodiments, joist platform system 1200 may be used together with bridge assembly 1100 where desired, although joist platform system 1200 may also serve as a primary alternative to bridge assembly 1100 in numerous use cases.

[0073] Each platform assembly 1202 includes platform 1204 positioned above a saddle 1206. Platform 1204 provides an upper support surface for a hand, knee (e.g., with or without pads), elbow, foot, tool, attachment 1600, kneeling support device 100, another type of kneepad, or another supported item during use. In numerous embodiments, platform 1204 is sized and shaped to support at least a portion of kneeling support device 100 while kneeling support device 100 is worn by the user and while platform assembly 1202 is coupled to joist 1290 or another framing member. In numerous embodiments, platform 1204 is sized and shaped to support kneeling support device 100 while kneeling support device 100 spans joists 1290 spaced about 12 inches on center, about 16 inches on center, or about 24 inches on center. In one embodiment, platform 1204 has a generally circular, generally flat, disc-like shape with a diameter of about 6 inches and platform assembly 1202 has an overall height of about 2 inches. In other embodiments, platform 1204 may have a smaller or larger diameter, for example, about 4 inches, about 5 inches, about 6 inches, about 8 inches, about 10 inches, about 10.5 inches, about 12 inches, about 14 inches, or another suitable diameter. In still other embodiments, the diameter of platform 1204 may fall within a selected range, for example, about 4 inches to about 11 inches, about 4 inches to about 10.5 inches, about 4 inches to about 6 inches, about 5 inches to about 7 inches, about 5 inches to about 8 inches, about 6 inches to about 10 inches, or about 8 inches to about 13 inches. Platform 1204 may have a circular, hexagonal, octagonal, rounded polygonal, or other suitable outer shape. The upper surface of platform 1204 may be generally flat, slightly textured, provided with an anti-slip surface treatment, or provided with indicia such as a logo or other marking. In certain embodiments, platform 1204 includes a chamfered peripheral edge to provide smoother engagement with kneeling support device 100 and reduce abrasive wear during repeated use, such as a chamfered edge 1500 shown in FIG. 15. In other embodiments, platform 1204 may include a rounded edge, a squared edge, or another edge profile according to desired comfort, molding, or wear characteristics.

[0074] In numerous embodiments, platform assembly 1202 has an overall height of about 2 inches. In other embodiments, platform assembly 1202 may have an overall height that is smaller or larger, for example, about 1.5 inches to about 3 inches, about 1.75 inches to about 3 inches, about 2 inches to about 3 inches, or another suitable height selected according to desired engagement with joist 1290, desired bite by teeth 1210, desired molding characteristics, or desired support characteristics. Saddle 1206 is positioned below platform 1204 and defines channel 1208 configured to receive an upper portion of joist 1290 or another framing member. As used herein, a framing member may include joists 1290, dimensional lumber, engineered wood, engineered I-joists, rafters, truss members, and other structural members having an upper edge or upper surface receivable within channel 1208. In numerous embodiments, saddle 1206 and channel 1208 are sized and shaped to seat onto nominal 2× lumber, for example, lumber having an actual width near 1.5 inches. In other embodiments, saddle 1206 and channel 1208 may have greater or lesser spacing to accommodate dimensional variations, engineered wood products, older homes having thicker joists, or other framing conditions. Channel 1208 may have a depth of at least about 1.75 inches in numerous embodiments. In other embodiments, channel 1208 may be deeper or shallower, for example, about 1.5 inches to about 2 inches, about 1.75 inches to about 2.5 inches, or about 2 inches to about 3 inches. When seated on joist 1290, platform assembly 1202 creates a stable support surface on a single joist 1290 such that no second joist and no plywood bridge are required. In numerous embodiments, that single-joist configuration can be beneficial where obstacles prevent a user from conveniently positioning a larger sheet or bridge structure across multiple joists 1290. In numerous embodiments, a user deploys a plurality of platform assemblies 1202 (e.g., four platform assemblies 1202 from a kit) across two or more joists 1290, framing members, or the like.

[0075] Teeth 1210 are located on the inside of channel 1208 and removably couple platform assembly 1202 to joist 1290. In numerous embodiments, teeth 1210 comprise alternating sets of guide teeth 1212 and compression teeth 1214 located on opposite inner portions of channel 1208. In certain embodiments, guide teeth 1212 have generally straight-triangular profiles and compression teeth 1214 have generally ascending-triangular profiles. Guide teeth 1212 and compression teeth 1214 may be discrete teeth, segmented teeth, ridge-like teeth, or other tooth forms while remaining guide teeth 1212 and compression teeth 1214. In one current embodiment, teeth 1210 include four sets of guide teeth 1212 and three sets of compression teeth 1214 arranged in alternating order along channel 1208, although greater or fewer numbers of guide teeth 1212 and compression teeth 1214 are contemplated. For example, channel 1208 may include two sets of guide teeth 1212 and one set of compression teeth 1214, three sets of guide teeth 1212 and two sets of compression teeth 1214, four sets of guide teeth 1212 and three sets of compression teeth 1214, five sets of guide teeth 1212 and four sets of compression teeth 1214, or other suitable arrangements. Each guide tooth 1212 may be opposed by another guide tooth 1212 on the opposite side of channel 1208, and each compression tooth 1214 may be opposed by another compression tooth 1214 on the opposite side of channel 1208. During seating of saddle 1206 onto joist 1290, guide teeth 1212 and compression teeth 1214 may engage joist 1290 substantially together. Guide teeth 1212 help align and center saddle 1206 on joist 1290, while compression teeth 1214 contribute removable retention once platform assembly 1202 is pressed downward into the seated position. Guide teeth 1212 and compression teeth 1214 may be integrally molded with saddle 1206 in numerous embodiments, while in other embodiments guide teeth 1212 and compression teeth 1214 may be separately formed and then coupled to saddle 1206.

[0076] Compression teeth 1214 may taper inwardly from a wider spacing near the opening of channel 1208 to a narrower spacing nearer the upper portion of channel 1208 where joist 1290 approaches the underside of platform 1204. In numerous embodiments, compression teeth 1214 do not substantially bite into joist 1290 until an upper portion of compression teeth 1214 engages joist 1290. For example, the upper 10% to 20% of the length of each compression tooth 1214 may provide the primary bite into wood of joist 1290. In other embodiments, bite may occur over an upper 10% to 30% of the length of compression teeth 1214. The angled slope of the compression teeth 1214 determine where the joist 1290 begins to be compressed by the compression teeth 1214, so it is feasible that 90-100% of the height of compression teeth 1214 can engage with the joist 1290 when a shallow angle is employed. A steeper angle, conversely, may result in the compression teeth 1214 only engaging and biting into the joist 1290 at the topmost 5% of the length. Opposing compression teeth 1214 may collectively bite into joist 1290 by a total amount of about 1 / 16 inch to about ¼ inch, with about ⅛ inch total being suitable in one present embodiment. The retention force provided by guide teeth 1212 and compression teeth 1214 may be tuned by varying tooth angle, tooth spacing, tooth height, saddle 1206 flexibility, material stiffness, channel 1208 dimensions, or combinations thereof. In numerous embodiments, retention of platform assembly 1202 on joist 1290 results from a combination of bite by compression teeth 1214, wedging or interference fit, and elastic deformation of saddle 1206. In numerous embodiments, that coupling resists rotation about the joist axis, resists longitudinal sliding along joist 1290, resists side-to-side wobble, and still permits lift-off by hand when desired. Platform assembly 1202 may therefore be removably retained on joist 1290 in a manner that is secure during use yet releasable without tools.

[0077] Brace ribs 1220 extend between platform 1204 and saddle 1206 and increase the structural rigidity and load-bearing stability of platform assembly 1202. In one current embodiment, platform assembly 1202 includes four brace ribs 1220 arranged around saddle 1206. Brace ribs 1220 may resist downward bending of platform 1204, resist torsional deflection from off-center loading, maintain the width of channel 1208, reinforce sidewalls of saddle 1206, and transfer loads from platform 1204 into saddle 1206 and the received joist 1290. In other embodiments, brace ribs 1220 may have different forms while retaining the same canonical structure and function. For example, brace ribs 1220 may be hollow, apertured, ribbed, latticed, buttressed, wall-like, tapered, stepped, curved, or combinations thereof. In some embodiments, one or more brace ribs 1220 include one or more apertures to reduce weight or material while preserving desired reinforcement. In some embodiments, brace ribs 1220 have the same height as sidewalls of saddle 1206. In other embodiments, brace ribs 1220 may have different heights than sidewalls of saddle 1206, for example, to tune stiffness, reduce weight, alter molding flow, or change load transfer into saddle 1206. In other embodiments, platform assembly 1202 may include three brace ribs 1220, four brace ribs 1220, five brace ribs 1220, six brace ribs 1220, or another number of brace ribs 1220. In numerous embodiments, platform 1204, saddle 1206, channel 1208, teeth 1210, brace ribs 1220, and carry apertures 1230 are formed together in a one-piece molded structure.

[0078] Carry apertures 1230 are formed in platform 1204 and facilitate carrying, lifting, repositioning, removal, storage, orientation, tethering, or attachment of platform assembly 1202. In one current embodiment, platform 1204 includes two opposing carry apertures 1230 positioned for one-hand gripping by a user, for example, with a thumb and one or more fingers, to carry platform assembly 1202 or pull platform assembly 1202 upward off joist 1290. In other embodiments, platform 1204 may include three carry apertures 1230, four carry apertures 1230, or another number of carry apertures 1230, for example, between about 2 and about 4 carry apertures 1230. Carry apertures 1230 may be round, elongated, slotted, oval, polygonal, or otherwise shaped. Carry apertures 1230 may be positioned symmetrically, oppositely, radially, quadrantly, offset, or otherwise arranged according to ergonomics, lifting mechanics, molding considerations, alignment with attachment 1600, or desired orientation cues. In numerous embodiments, the location of carry apertures 1230 is selected not only for carrying comfort but also to facilitate outward flexing of saddle 1206 during lift-off. For example, a user may grasp platform assembly 1202 with one or two hands and apply upward force through opposing carry apertures 1230 to elastically expand saddle 1206 and reduce engagement of teeth 1210 (especially compression teeth 1214) with joist 1290, thereby making removal and lift-off easier. Carry apertures 1230 may therefore cooperate with the flexibility of saddle 1206 and the placement of teeth 1210 to permit secure removable retention during use and easier manual removal when desired. Carry apertures 1230 may also provide an orientation reference such that platform assembly 1202 can be grasped and placed quickly, including in dimly lit or insulated spaces where direct visual alignment may be difficult.

[0079] Platform assembly 1202 may be formed as a one-piece, molded, monolithic part in numerous embodiments. Injection-molded polymer embodiments are preferred for current commercial implementation. Suitable polymeric materials include nylon, polyamides, polypropylene, polyethylene, high-density polyethylene (HDPE), polycarbonate, acrylonitrile butadiene styrene (ABS), polyetherimide (PEI), polyoxymethylene (POM), acrylonitrile styrene acrylate (ASA), and glass-filled versions of one or more of those materials. Reinforced polymer embodiments are also contemplated, including polymers reinforced with glass fibers, carbon fibers, aramid fibers, mineral fillers, or other reinforcement materials. Additional embodiments may employ graphene-containing materials or other enhanced polymer formulations. Although polymeric construction is preferred in numerous embodiments, platform assembly 1202 may also be formed primarily of cast aluminum while still including carry apertures 1230, teeth 1210, and brace ribs 1220. Platform assembly 1202 may be manufactured by injection molding, casting, machining, additive manufacturing, thermoforming, compression molding, or other suitable techniques. The selected material and construction may provide sufficient strength and rigidity to support a user carrying tools or supplies while kneeling, crawling, shifting weight, or staging equipment on platform assembly 1202. In certain embodiments, platform assembly 1202 has sufficient flexibility such that upward lifting force applied through carry apertures 1230 elastically expands saddle 1206 and reduces engagement of teeth 1210 with joist 1290 to facilitate removal of platform assembly 1202 from joist 1290.

[0080] In some embodiments, platform assembly 1202 is glow-in-the-dark or otherwise includes one or more light-emissive or light-visible features to improve safety and locate platform assemblies 1202 in dark work environments. For example, platform assembly 1202 may be formed largely of a glow-in-the-dark material, coated with a glow material, or provided with one or more inserts, markings, or indicia having glow characteristics. Glow features may extend across substantially the entire platform assembly 1202 or may be limited to selected regions, such as platform 1204, carry apertures 1230, peripheral markings, logos, or other indicia. In other embodiments, glow features may be positioned adjacent carry apertures 1230 to facilitate location and removal of platform assembly 1202 in dark spaces. Such embodiments may help mark a safe path in an attic or other dark workspace and may also help a user locate an individual platform assembly 1202 after repositioning tools, disturbing insulation, or changing work position. In other embodiments, platform assembly 1202 may include reflective features, phosphorescent features, photoluminescent features, or combinations thereof.

[0081] Platform caddy 1400 may hold and carry multiple platform assemblies 1202 together as a compact kit. In one current embodiment, platform caddy 1400 is configured to hold four platform assemblies 1202 in a stacked arrangement and includes a carry handle 1410, base 1420, and retaining wall assembly 1430. The retaining wall assembly 1430 may include solid-wall sections 1432 connected by one or more bridges 1434 or other spanning member or wall section including one or more apertures. In some embodiments, a platform caddy 1400 configured to carry four platform assemblies 1202 can be sufficient for many crawling and working tasks while remaining compact enough for convenient transport into attics and other confined workspaces. Other quantities are also contemplated, however, including two, three, six, eight, twelve, sixteen, or other numbers of platform assemblies 1202. In certain embodiments, a user may carry multiple joist platform systems 1200 together. Platform caddy 1400 may hold platform assemblies 1202 in a stacked arrangement, nested arrangement, offset arrangement, divided arrangement, or another carrying arrangement. Platform caddy 1400 may retain platform assemblies 1202 by gravity, by partial enclosure, by a removable strap, by a cover, by a latch, by interlocking fit, or by another suitable holding arrangement. Platform caddy 1400 may include a carry handle 1410, side handle, strap, cover, latch, partial enclosure, or another retention feature while remaining platform caddy 1400. In one current dimensional example, platform caddy 1400 has a base 1420 portion of about 2 inches and receives four platform assemblies 1202 each having a height of about 2 inches to form a stack about 10 inches tall, although other caddy and stack dimensions are contemplated. Each platform assembly 1202 may be sized to be received in platform caddy 1400 in the stacked arrangement. Platform caddy 1400 may therefore hold and carry multiple platform assemblies 1202 together in a portable joist platform system 1200 kit. Platform caddy 1400 may include a double saddle 1422 on the base 1420 to allow for mounting onto joist 1290 in two different directions, as depicted in FIGS. 14A-14C (e.g., double saddle 1422 can mount on joist 1290 in two roughly orthogonal directions). The base of platform caddy 1400 may also employ a variation of saddle 1206 in other embodiments.

[0082] During use, a user may place one or more platform assemblies 1202 onto joists 1290 along a desired path of travel, for example, while entering an attic work area, moving parallel to joists 1290, or repositioning within a selected work region. In numerous embodiments, the user wears one kneeling support device 100 or a pair of kneeling support devices 100 while using platform assemblies 1202. Platform assemblies 1202 may be leapfrogged, spread across a work area, or both, depending on the task and available joists 1290. Once at a selected work location, the user may spread platform assemblies 1202 across the work area to increase available support area and reduce wobbly movements that may otherwise occur on narrow joist surfaces. Because platform assemblies 1202 engage individual joists 1290 and do not require bridging to another joist, platform assemblies 1202 may be particularly convenient where blown insulation, pipes, wires, ductwork, or framing obstacles limit the usefulness of plywood or larger bridging structures. Joist platform system 1200 may be used in attics, crawlspaces, unfinished basements, open framing, inspection environments, maintenance environments, and construction environments. Those features can be beneficial for insulators, electricians, heating, ventilation, and air conditioning technicians, plumbers, pest-control workers, and home inspectors, although joist platform system 1200 is not limited to those trades.

[0083] FIGS. 16A-16C depict non-limiting embodiments of attachment 1600 configured to cooperate with platform assembly 1202. Attachment 1600 includes attachment base 1620 configured to seat on top of platform 1204. In numerous embodiments, one or more orientation bosses 1630 protrude downward from attachment base 1620 and are received in carry apertures 1230 to orient attachment 1600 relative to platform assembly 1202 and reduce rotation or sliding between the parts. Attachment base 1620 may further include retaining skirt 1640 protruding downward and configured to engage an outer edge of platform 1204. Retaining skirt 1640 may be complete, partial, segmented, continuous, tapered, stepped, flexible, rigid, or combinations thereof while remaining retaining skirt 1640. Depending on the embodiment, attachment 1600 may sit on top of platform 1204, around platform 1204, or both. In numerous embodiments, attachment 1600 is retained on platform 1204 by gravity alone, by orientation bosses 1630, by retaining skirt 1640, or by combinations thereof. Orientation bosses 1630 may comprise one, two, three, four, or more projections and may have round, oval, polygonal, tapered, or other outer profiles. In numerous embodiments, the size and shape of orientation bosses 1630 correspond to the size and shape of carry apertures 1230 to provide desired alignment and fit. Attachment 1600 may include a handle 1610 or other member sized and shaped for carrying. The primary purpose of attachment 1600 may be to operate as a container, tray, tool holder, parts holder, cup, bin, instrument holder, fastener holder, or another work accessory. In some embodiments, attachment 1600 includes joist-engaging structure (e.g., similar to saddle 1206, double saddle 1422, a saddle including a channel or teeth, or the like) while in other embodiments attachment 1600 relies on platform 1204 for joist support.

[0084] FIGS. 17A and 17B depict non-limiting embodiments of attachment 1600 configured to be used in or with joist platform system 1200. Attachment 1600 may comprise a plumbing glue caddy as shown in FIGS. 17A and 17B. Attachment 1600 can be sized and shaped to house a variety of tools or materials a user would use to perform a task (e.g., tools, flashlight / lighting, repair components, building materials, fasteners, adhesives, personal items, a cellular phone, miscellaneous items, and so forth). In some embodiments, base 1620 comprises a double saddle 1422 instead of orientation bosses 1630 and / or retaining skirt 1640. Embodiments employing a double saddle 1422, saddle 1206, or other joist-mounting member are configured to mount on a joist 1290 or other support structure as described above. Here, the double saddle 1422 includes numerous teeth 1210 to secure the attachment 1600 onto joist 1290. Teeth 1210 may be guide teeth 1212, compression teeth 1214, or a combination of the two depending on how tight of a fit onto joist 1290 is desired. FIG. 17B depicts a double saddle 1422 design employing one compression tooth 1214 positioned between two guide teeth 1212.

[0085] FIGS. 18A-18C depict non-limiting embodiments of attachment 1600 configured to be used in or with joist platform system 1200. Here, attachment 1600 comprises a toolbox with multiple compartments. A double saddle 1422 can be sized and shaped differently based on the size and configuration of attachment 1600. A double saddle 1422 or other joist-mounting member can include teeth 1210, guide teeth 1212, compression teeth 1214, or other compression or mounting features. A toolbox attachment 1600 can mount on joist 1290 using a double saddle 1422 or a variety of different multi-saddles or other joist-mounting members. In some embodiments, toolbox attachment 1600 can mount onto platform assembly 1202 instead of directly mounting onto joist 1290. FIGS. 16A through 18C illustrate non-exclusive examples of attachment 1600 being capable of housing a wide variety of useful items normally carried in a tool belt, traditional toolbox, bucket, or other container. Attachment 1600 allows a user to conveniently access necessary tools and materials while reducing: lost items, damage to attic insulation, and tipping heavy items onto or through drywall ceilings. A tool bag can easily snag on adjacent attic features or dump out tools when a user is crawling and working with kneepads. The various disclosed embodiments of attachment 1600 reduce or eliminate the need for a user to carry a tool bag into attics and other awkward / confined spaces.

[0086] It should be understood that joist platform system 1200 is not limited to the specific configurations described above. Platform 1204, saddle 1206, channel 1208, teeth 1210, guide teeth 1212, compression teeth 1214, brace ribs 1220, carry apertures 1230, platform caddy 1400, handle 1410, base 1420, double saddle 1422, retaining wall assembly 1430, solid-wall sections 1432, bridge 1434, attachment 1600, handle 1610, attachment base 1620, orientation bosses 1630, and retaining skirt 1640 may each vary in number, shape, size, material, arrangement, and relative position according to desired performance characteristics. Different combinations of those features may be employed together with kneeling support device 100, bridge assembly 1100, or both. Any feature of platform 1204, saddle 1206, channel 1208, teeth 1210, guide teeth 1212, compression teeth 1214, brace ribs 1220, carry apertures 1230, platform caddy 1400, handle 1410, base 1420, double saddle 1422, retaining wall assembly 1430, solid-wall sections 1432, bridge 1434, attachment 1600, handle 1610, attachment base 1620, orientation bosses 1630, and retaining skirt 1640 may be combined with any other compatible feature described herein. The figures and descriptions herein are therefore intended to illustrate selected embodiments and not to limit the disclosure to any single configuration.

[0087] Various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the present disclosure. While the embodiments described above refer to particular features, the scope of this disclosure also includes embodiments having different combinations of features and embodiments that do not include all of the described features. Accordingly, the scope of the present disclosure is intended to embrace all such alternatives, modifications, and variations as fall within the scope of the claims, together with all equivalents thereof.

[0088] What has been described above includes examples of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Accordingly, the claimed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.

[0089] It will be understood that implementations of the kneeling support device and system include but are not limited to the specific components disclosed herein, as virtually any components consistent with the intended operation of various kneeling support device and system may be utilized. Accordingly, for example, it should be understood that, while the drawings and accompanying text show and describe particular kneeling support device and system implementations, any such implementation may comprise any shape, size, style, type, model, version, class, grade, measurement, concentration, material, weight, quantity, and / or the like consistent with the intended operation of kneeling support device and system.

[0090] The concepts disclosed herein are not limited to the specific kneeling support device and system shown herein. For example, it is specifically contemplated that the components included in particular kneeling support device and system may be formed of any of many different types of materials or combinations that can readily be formed into shaped objects and that are consistent with the intended operation of the kneeling support device and system. For example, the components may be formed of: rubbers (synthetic and / or natural) and / or other like materials; glasses (such as fiberglass), carbon-fiber, aramid-fiber, any combination therefore, and / or other like materials; elastomers and / or other like materials; polymers such as thermoplastics (such as ABS, fluoropolymers, polyacetal, polyamide, polycarbonate, polyethylene, polysulfone, and / or the like, thermosets (such as epoxy, phenolic resin, polyimide, polyurethane, and / or the like), and / or other like materials; plastics and / or other like materials; composites and / or other like materials; metals, such as zinc, magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel, spring steel, aluminum, and / or other like materials; and / or any combination of the foregoing.

[0091] Furthermore, kneeling support device and system may be manufactured separately and then assembled together, or any or all of the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously, as understood by those of ordinary skill in the art, may involve 3-D printing, extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and / or the like.
