[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 088,239, filed October 6, 2020, which is incorporated herein by reference in its entirety. Background Technology

[0003] The present invention generally relates to ladders, and more particularly to top covers, accessory trays or attachments, and ladders including such top covers, accessory trays or attachments.

[0004] Ladders are commonly used to provide users with improved access to elevated locations that would otherwise be inaccessible. Ladders come in a variety of shapes and sizes, such as straight ladders, straight telescopic ladders, movable ladders, and combination ladders and telescopic ladders. So-called combination ladders can combine many of the benefits of various ladder designs in a single ladder.

[0005] Ladders known as live ladders are self-supporting, meaning they do not require support from walls, pillars, or other structures for stability. Instead, a live ladder can be positioned on the floor (or other similar surface) so that at least three legs (and typically four) provide a stable support structure for the user to climb, even in open spaces (e.g., outside or in the middle of a room) where there are no walls, roofs, pillars, or other types of structures necessary for the ladder's stability.

[0006] Typically, users expect to handle various items while standing on a ladder, including tools (e.g., screwdrivers, putty knives, paintbrushes, hammers, wrenches, power tools, etc.) and supplies (nails, screws, paint, etc.). The ability to keep tools and supplies within reach while on a ladder, eliminating the need for constant climbing to change tools or obtain new supplies, saves users time and energy and provides a safer experience.

[0007] The industry has always aspired to provide ladders and ladder components that are safe, efficient, and effective tools for their users. Numerous efforts have been and will continue to be made to improve ladder performance, refine associated manufacturing processes, and provide end-users with a superior experience when using ladders.

[0049] Reference Figure 1 and Figure 2 The image shows a ladder 100 according to an embodiment of the present invention. Figure 1 The ladder 100 shown is generally configured as a platform-type ladder and includes a first component 102 having paired, spaced-apart ladder frames 104 and a plurality of rungs 106 extending between the ladder frames 104 and coupled to them (e.g., by mechanical fasteners, adhesives, or material bonding techniques). The rungs 106 are substantially uniformly spaced, parallel to each other, and configured to be substantially horizontal when the ladder 100 is in the desired orientation, thereby allowing them to function as “steps” to support a user as they ascend the ladder 100, as will be understood by those skilled in the art. In various embodiments, the upper surface of the rungs 106 may include adhesive friction features (e.g., grooves and ridges, grip tape, rubber coverings, or other anti-slip features) to provide adhesive friction when a user stands on the rungs 106.

[0050] The ladder 100 also includes a second component 108 having paired, spaced-apart ladder frames 110. The second component 108 may also include transverse members or other structural components extending between the ladder frames 110 to provide structural support and strength to the spaced-apart ladder frames 110 at a desired level. In some embodiments, the transverse members of the second component 108 may be configured as steps to support a user. Thus, for example in Figure 1 As generally shown, the second component 108 can be used to help support the ladder 100 in the desired operating state.

[0051] exist Figure 1In the illustrated embodiment, a hinged or pivotal connector 114 (also referred to as a hinge) joins the first ladder frame assembly 102 and the second ladder frame assembly 108 together such that the two assemblies 102 and 108 can be closed or folded into a stored or stowed state. When in the stowed state, the first ladder frame assembly 102 and the second ladder frame assembly 108 are positioned adjacent to each other with relatively thin profiles, as will be understood by those skilled in the art.

[0052] It should be noted that, in Figure 1 and Figure 2 In the illustrated embodiment, the ladder frame 104 of the first component 102 extends significantly beyond the hinged connector 114 and is coupled to the top cover 116. In such an embodiment, the extended ladder frame 104 and the top cover 116 can be used as a storage tray for tools, supplies, or other materials, which will be discussed in further detail below. Additionally, the top cover 116 can be used as a handrail to help support or balance a user when standing on the ladder 100. However, it should be noted that various features and aspects of the invention can also be applied to and contemplated for combination with other types of ladders, including, for example, movable ladders with conventional top covers directly coupled to both the first and second components (e.g., at least one of the first and second components is pivotally coupled to the top cover), as well as telescopic ladders, straight ladders, combination ladders, or other types of ladders. Some non-limiting examples of ladders and related components that can be used in various embodiments of the invention include those described in U.S. Patent Publication No. US2018 / 0298691, published October 18, 2018, and U.S. Patent No. 9,422,767, published August 23, 2016, the disclosures of which are incorporated herein by reference in their entirety.

[0053] exist Figure 1 and Figure 2 In the illustrated embodiment, platform 118 is positioned above step 106 and extends from step 104 of first component 102 to step 110 of second component 108. Platform 118 may be configured to support all or at least most of a user's feet, thereby providing a comfortable and safe working surface for the user. In the currently described embodiment, platform 118 is hinged to step 104 of first component 102 and engages a transverse member associated with second component 108. In one embodiment, platform 118 may simply rest on the associated transverse member. In another embodiment, a locking member may be used in the deployed state or position to selectively engage platform 118 and the associated transverse member. In some embodiments, [the following is possible:] Figure 1 In the indicated position, an actuable latching member 120 is used to selectively lock (and release) the platform 118 relative to the second component 108.

[0054] The first component 102 and the second component 108 can be formed from a variety of materials and using a variety of manufacturing techniques. For example, in one embodiment, the ladder frames 104 and 110 can be formed from composite materials such as fiberglass, while the steps and other structural components can be formed from aluminum or aluminum alloys. In other embodiments, substantially all components of the assembly can be formed from aluminum or aluminum alloys. In other embodiments, components 102 and 108 (and their various components) can be formed from other materials, including other composite materials, plastics, polymers, various metals, and metal alloys.

[0055] The ladder 100 may also include various supports, structural reinforcements, and other components such as those described in previously incorporated U.S. Patent Publication No. US2018 / 0298691 and U.S. Patent No. 9,422,767.

[0056] The ladder 100 may further include an accessory, also referred to as a tray 122, and is coupled to the top cover 116. In some embodiments, the tray 122 may be coupled to the ladder frame 104 of the first component 102 at a location between the hinge 114 and the top cover 116. The tray 122 can be selectively positioned and held in a variety of positions, including, for example, a first position in which the tray 122 extends upward from the top cover 116, a second position in which the tray 122 extends outward and grounded (generally horizontally) from the top cover 116, and a third position in which the tray 122 extends downward from the top cover 116 (e.g., as shown in the image). Figure 1 The tray is positioned in a third position (as shown) such that it is positioned above hinge 114 and adjacent to (or even against) the upper portion of the ladder frame 104 of the first component 102. A non-limiting example of such an attachment is further described in detail in U.S. Patent Application No. 16 / 891,937, filed June 3, 2020, the disclosure of which is incorporated herein by reference in its entirety.

[0057] Now refer to Figures 3 to 11 The illustration shows a top cover according to an embodiment of the invention. The top cover 116 may be generally formed as a body 130, which is configured for connection to a ladder frame (e.g., a ladder frame) of one or more components of a ladder. Figure 1 and Figure 2The ladder 100 shown herein includes a ladder frame 104 and various features to be discussed herein. For example, the body 130 may include or define various openings or through-holes. In some embodiments, these openings or through-holes may include one or more elongated openings or through-holes 132a and 132b that may be configured to receive part of a tool, such as a blade of a putty knife or scraper. These openings 132a and 132b may be large enough to receive part of the tool (e.g., the blade) while obstructing the passage of another part of the tool (e.g., a handle attached to the blade). Thus, a user of the ladder 100 can store such tools at the top of the ladder where the user would expect to periodically access them while working on a particular project. In one embodiment, these elongated through-holes may be positioned near the lateral edge of the top cover 116, close to where the top cover connects to the ladder frame.

[0058] The body 130 of the top cover 116 may include or define various other openings or through-holes, such as through-holes 134, 136a and 136b, 138a-138c, and 140a and 140b. In some embodiments, these through-holes may be used to hold or store various tools (e.g., screwdrivers, hammers, wrenches, paintbrushes, etc.). In some examples, some of these through-holes (e.g., through-holes 140a and 140b located on the front of the body 130) may be configured to receive clips or latches to hold other tools or items in the top cover 116 for storage. Another through-hole 142 may be sized to receive larger items for storage, including, for example, the chuck end of a drill. In some embodiments, one or more through-holes 144 may have an open (i.e., unclosed) perimeter, allowing for the reception of extension members (e.g., knots formed in a rope, balls or ball handles attached to a portion of a rope) that are connected to other objects. For example, a ring-shaped elastic cord can be attached to the tool, and a ball or ball handle attached to the elastic cord can be held in a through hole 144 in the side opening to hold the tool (or other object) from the top cover 116.

[0059] In addition to openings or through-holes, one or more closed-bottomed compartments or recesses 146a and 146b may be formed in the body 130 of the top cover 116 for storing various items (e.g., screws, nails, other tools or devices, etc.). Storage compartment 146a may be positioned between the sidewalls (e.g., 162a) of at least one retaining structure (e.g., 160a). In some embodiments, one or more retaining structures (e.g., 160b, 160c) may be positioned between the sidewalls (e.g., 162a) of the retaining structure (e.g., 160a). Additionally, at least as... Figure 7As shown, the additional retaining structures (e.g., 160b, 160c) can be positioned off-center from the centerline of the first retaining structure, or in other words, the centerline between the sidewalls of the additional retaining structures (e.g., each pair of sidewalls 162b and 162c) can be spaced apart from the centerline between the sidewalls of the first retaining structure (e.g., 162a). By being positioned off-center from the centerline of the larger retaining structure (e.g., 160a) and asymmetrically away from the top cover, the space within the larger retaining structure can be used for a variety of purposes, such as by including additional, smaller, nested retaining structures and at least one recess, compartment, or through-hole (e.g., 146a) not within one of the smaller retaining structures. Thus, a user can retain a smaller container within a smaller retaining structure without using the larger container (e.g., held by the larger retaining structure 160a) and simultaneously use compartment 146a.

[0060] Other features of the body 130 may include portions for connection to the ladder frame (e.g., portion 148) and portions for connection to the accessory tray 122 (e.g., portion 150). In some embodiments, it should be noted that the top cover 116 may not be configured to be mounted to the accessory tray 122. This connection between the top cover 116 and the accessory tray 122 is described in U.S. Patent Application 16 / 891,937, previously incorporated by reference. In some embodiments, the top cover 116 may be configured to be connected to the ladder frame from both the front and rear ladder frame assemblies, and may further be configured to be pivotally connected to some of these ladder frames.

[0061] Additionally, the top cover 116 may include retaining structures configured, for example, to attach a paint can or similar structure to the top cover 116. This feature may be configured to prevent the paint can from tipping over or spilling when it is located at the top of the ladder. For example, the retaining features may include one or more grooves and shoulders formed in the sidewall portion of the body 130.

[0062] exist Figures 3 to 11 In the embodiment shown, three separate retaining structures 160a, 160b, and 160c are provided, each configured to hold or retain a tank or container of a different size. Each of the retaining structures 160a, 160b, and 160c may include one or more sidewalls 162a, 162b, and 162c, and these sidewalls may each have an associated lip or shoulder 164a, 164b, and 164c located at the upper end of the sidewall (“upper” is a relative term when considering the top cover 116 in the desired use orientation, e.g., in…) Figures 1 to 2As shown in the diagram. Taking the second retaining structure 160b as an example, the sidewall 162b may include a first segment and a second segment that extend upward from the base plate region 165 and are oriented relative to each other at a defined angle β. For example, the first substantially linear segment 166a and the second substantially linear segment 166b may extend at an angle of approximately 10 degrees. In other embodiments, these two segments may extend to form an angle of approximately 9 to approximately 11 degrees. In yet another embodiment, these two segments may form an angle of approximately 8 to approximately 12 degrees. A third sidewall segment 166c may extend between and connect the first two segments 166a and 166b. In one embodiment, the third segment 166c may include an arcuate segment (e.g., a semicircle), and the three segments 166a-c may be configured to provide substantially continuous sidewalls. In other embodiments, the retaining structure may include two separate sidewalls having, for example, an associated lip or adjacent shoulder shown with respect to the first retaining structure 160a (e.g., in...). Figures 3 to 11 In the illustrated embodiment, there is no arcuate segment in the first retaining structure 160a. For example, as described above, the two walls can be positioned relative to each other at an angle β.

[0063] In some embodiments, the lip or shoulder 164b may be positioned over the entire sidewall 162b (i.e., extending along the entire length of each segment 166a-c). In other embodiments, the lip or shoulder 164b may be positioned over a portion of one or more segments. In some embodiments, the lip or shoulder is a structure extending perpendicular to another surface (e.g., a sidewall). The lip or shoulder may also be defined as a portion of material extending cantilevered from another surface or laterally over a substantially vertical sidewall surface. For example, as... Figure 5 and Figure 6 As shown, shoulder 164b may include a first segment or portion extending along the length of a first sidewall segment 166a and partially extending along a third segment. Shoulder 164b may include a second segment or portion extending along the length of a second sidewall segment 166b and partially extending into a third sidewall segment 166c. A portion of the third sidewall segment 166c does not have any lip or shoulder along its upper edge. In some embodiments, shoulder 164b may extend only partially along the length of the first sidewall segment 166a and / or only partially along the length of the second sidewall segment 166b. For example, a portion of one or both of the sidewall segments 166a and 166b may not have a lip or shoulder along its upper edge near the front of the top cover, instead of having a lip or shoulder. Figure 5 and Figure 6The arrangement shown extends fully to the front edge. This limited shoulder length allows for easier insertion of the container into the retaining structure 160 by allowing vertical insertion at the front of the top cover and then horizontal insertion below the shoulder 164b. In some embodiments, additional retaining structures 160a and 160c may be constructed in a manner substantially similar to that of retaining structure 160b. For example, each of retaining structures 160a and 160c includes sidewalls having sections extending relative to each other at an angle (e.g., at an angle substantially the same as that of retaining structure 160a). For retaining structure 160a, two sidewall sections are not connected by a third section to provide a single continuous sidewall. However, each sidewall section may include linear and curved portions, as described in the figures.

[0064] For example in Figure 4 and Figure 8 As observed, a container or tank can be coupled to a top cover 116 using one of the retaining structures. For example, a paint can 170 may include a lower lip 172 that slides laterally into a lateral groove formed by a sidewall 162a and an associated lip or shoulder 164a from the front side of the top cover 116 toward the rear of the top cover 116, thereby coupling the paint can 170 to the top cover 116. In some embodiments, the angled configuration of the retaining structure 160a allows the paint can 170 to wed into the sidewall segments, thereby creating an interference fit in addition to capturing the lower lip 170 within the sidewall groove. Additionally, the sidewall 160a may include a generally straight first portion and a curved or angled second portion relative to the first portion. The lip or shoulder on the sidewall may also include adjacent straight and curved or angled segments. For example, as Figure 7 As shown, a portion of the sidewall 162a near the front of the top cover 116 (i.e., at the bottom / front of the top cover in the drawing and on the side including the side openings for retaining structures 160b and 160c) can be substantially straight and can transition to a slightly angled or curved portion near the opposite end of the sidewall 162a (i.e., at the back of the top cover). This allows the paint can 170 or other containers to be stably secured to the top of the top cover 116, even if the ladder is slightly tilted to one side or the other. The angled or curved portions of the sidewalls 162a, 162b, and 162c also help improve container wedging and prevent the container from passing completely through the retaining structure 160a.

[0065] The retaining structures 160a-c can be configured to each accommodate containers of different sizes. For example, the first retaining structure 160a can be configured to accommodate a one-gallon paint can, the second retaining structure 160b can be configured to accommodate a one-quart paint can, and the third retaining structure 160c can be configured to accommodate a one-pint paint can. Of course, other sizes can also be accommodated as needed. The first or top retaining structure 160a may have an opening at the front of the top cover and an opening at the back of the top cover, while the second retaining structure 160b and the third retaining structure 160c may have an opening at only one of the front or back locations. Figure 7 In some embodiments, the second retaining structure 160b and the third retaining structure 160c have openings on the front of the top cover to facilitate insertion of the bottom of the tank or container from the front side of the ladder (i.e., in typical use, when the user climbs the steps, facing him or his side). The top or highest retaining structure 160a may have an open end on the back of the top cover to allow reception and securing (via the lip or shoulder) of tanks or containers large enough to suspend them from the back of the top cover when secured by the retaining structure 160a.

[0066] Although Figures 3 to 11 The illustrated embodiment shows a retaining structure formed by sidewalls and overhanging lip or shoulder portions, but in other embodiments, the retaining structure may be formed in different ways or exhibit different constructions. For example, in one embodiment, the retaining structure may include sidewalls extending upward from the base plate (e.g., sidewall 164b extending from the base plate 165) to form acute angles between these sidewalls. Thus, the retaining structure may form a generally V-shaped groove (e.g., when observing the profile), rather than... Figures 3 to 11 The diagram shows a generally C-shaped profile. Such a profile can still capture and retain the lip or other features of a paint can or similar container to stably hold it in place. In other embodiments, the retaining structure can be formed as lateral grooves to exhibit an arcuate cross-sectional profile.

[0067] The top cover 116 can be formed from a variety of materials using various manufacturing techniques. In one embodiment, the top cover 116 can be formed from a material such as plastic using a suitable molding process, creating a monolithic, uniform component. In other embodiments, the top cover 116 can be formed either as a monolithic component or from multiple individual components made of any of a variety of materials, including, for example, plastics, metals, composites, or combinations thereof.

[0068] Although retaining structures 160a-c are described as being associated with top cover 116, these retaining structures may alternatively or additionally be formed in or otherwise associated with pallet 122 such that when pallet 122 is in the desired position relative to top cover 116 or associated ladder frame (e.g., 104), the container or tank can be stably coupled to and supported by the pallet 122.

[0069] Furthermore, the retaining structure may be formed in or associated with another accessory, which may include removable or detachable accessories. For example, Figure 12 A perspective view of a ladder 200 is shown, which includes a first component 202 having paired, spaced-apart ladder frames 204 and a plurality of runners 206 extending between and connected to the ladder frames 204. For convenience, the runners 206 and ladder frames 204 of the first component 202 are shown.

[0070] The steps 206 are spaced apart, substantially parallel to each other, and are configured to be substantially horizontal when the ladder 200 is in the desired orientation, so that the steps 206 can be used as “steps” for a user to climb the ladder 200, as understood by one of ordinary skill in the art. In various embodiments, the upper surface of the steps 206 may include adhesive friction features (e.g., grooves and ridges, grip tape, or other anti-slip features) to provide adhesive friction when a user stands on the steps 206.

[0071] The ladder 200 also includes a second component 208 having paired, spaced-apart ladder frames 210. A plurality of rungs 212 extend between and connect to the spaced-apart ladder frames 210. The rungs of the second component 208 are spaced apart, substantially parallel to each other, and are configured to be substantially horizontal when the ladder 200 is in the desired use orientation, thereby allowing the rungs 212 to function as “steps” for a user to climb the ladder 200. In various embodiments, both the top and bottom surfaces of the rungs 212 may include adhesion friction features (e.g., grooves and ridges, grip tape, or other anti-slip features) to provide adhesion friction when a user stands on the rungs 212.

[0072] The top cover 216 can be connected to the upper portion of the ladder frame 204 of the first component and is configured to support the user's weight when the user stands on the top cover 216. The upper surface of the top cover 216 may also include adhesive friction or anti-slip features to provide adhesive friction to the user when the user stands on it.

[0073] The second component 208 is pivotally connected to the first component 202 via a pair of hinge components 220 (which, for simplicity, are sometimes referred to herein as "hinges"). In the illustrated embodiment, the hinges 220 are spaced apart from the top cover 216 along the length of the front ladder frame 204 of the first component 202. The hinges 220 can be configured to selectively lock the first component 202 and the second component 208 in one or more desired positions relative to each other. Thus, for example, in Figure 12 In this configuration, the first component 202 and the second component 208 are locked such that the ladder frame 210 of the second component 208 extends from the front ladder frame 204 at an angle of approximately 180 degrees. In other words, the front ladder frame 204 and the rear ladder frame 210 extend relative to each other in a generally parallel manner, with a substantial portion of the second component 208 extending upwards and beyond the top cover 216. This configuration, which can be considered a straight ladder construction, provides the user with the ability to reach extended heights (beyond the height of a movable ladder construction) when the ladder 200 rests against a suitable supporting surface (e.g., a wall or roof edge).

[0074] Hinge 220 also allows the second component 208 to be selectively rotated relative to the first component 202, thereby positioning (and locking) the rear ladder frame 210 to extend at an acute angle relative to the front ladder frame 204, thus placing the ladder in a movable ladder configuration. In yet another configuration, hinge 220 allows the second component 208 to be selectively rotated relative to the first component 202, so that the rear ladder frame 210 can be positioned (and locked) to extend downward away from the top cover 216, wherein the ladder frames 202 and 210 of each component are positioned adjacent to each other, thereby placing the ladder in a folded storage state. Various other details and examples associated with such a ladder are described in U.S. Patent Application Publication No. US2019 / 0376341, published December 12, 2019, the disclosure of which is incorporated herein by reference in its entirety.

[0075] The ladder 200 also includes an attachment 230 that engages with the ladder frame 210 of the second component 208. In one embodiment, the attachment 230 may include a pair of recesses or notches formed in its body for receiving and engaging with a pair of ladder frames (e.g., the ladder frame 210 of the second component 208) to attach the attachment 230 to the ladder. In some embodiments, the attachment 230 may be removably engaged with the ladder frame 210 of the second component 208 (using removable screws, bolts, or latching devices) and then used or removed by the user of the ladder as needed. In some cases, the attachment 230 may be positioned adjacent to, or even in place of, a rung 212 and effectively secured to the ladder frame 210 of the second component 208 such that the user cannot easily remove the attachment 230 in a non-destructive manner (e.g., by drilling through rivets or other fasteners or by breaking the adhesive or material bond between the attachment and the ladder frame). Therefore, when ladder 200 is in a ladder configuration or storage configuration, attachment 230 is positioned toward the "bottom" of the second component 208. Additionally, attachment 230 is sized, shaped, and positioned such that it does not interfere with the second component 208 and the first component 202 when placed in the storage state. In one embodiment, attachment 230 may include one or more retaining structures, similar to those described above (e.g., retaining structures 160a-c), configured to securely and stably hold a tank, such as a paint can or similar structure, on its top or bottom surface.

However, it should be understood that the invention is not intended to be limited to the specific forms disclosed. Additionally, features of one embodiment can be combined with features of other embodiments without limitation. Rather, the invention includes all modifications, equivalents, and substitutions falling within the spirit and scope of the invention as defined by the appended claims.
