[0087] Referring generally to the accompanying drawings, various embodiments of mobile units, storage devices, and / or structures are illustrated. Mobile devices are used on construction sites to help workers move and hold tools and equipment. This application provides a mobile device (e.g., a mobile work trolley) having multiple coupling mechanisms for easy carrying and connection to a variety of usable tools and equipment.

[0088] refer to Figures 1 to 5 The illustration shows a container, unit, device, and / or mobile tool support (shown as a mobile work trolley 10) according to exemplary embodiments. The mobile work trolley 10 is configured to move and support tools and equipment at a work site. The mobile work trolley 10 includes: an upper portion (shown as an upper housing 12); a lower portion (shown as a lower housing 18); and a vertical connecting portion (shown as one or more legs 26) extending from the lower housing 18 to the upper housing 12, such that the upper housing 12 is above the lower housing 18. In a specific embodiment, the legs 26 are arranged at and connected to the four corners of the upper housing 12 and the lower housing 18.

[0089] One or more wheels 28 are coupled to the lower housing 18. In various embodiments, multiple wheels are coupled to the lower housing 18. In a particular embodiment, two wheels 28 are rotatably coupled to a pivotable wheel housing 30 (which is pivotally coupled to a first end 22 of the lower housing 18), and two wheels are rotatably coupled to a wheel housing 34 (which is fixedly coupled to the opposite second end 24 of the lower housing 18). The pivotable wheel housing 30 rotates relative to the lower housing 18, thereby allowing the mobile work trolley 10 to move more easily. The pivotable wheel housing 30 is permitted to change position relative to the lower housing 18, such that the axis of rotation of the wheels 28 can be adjusted relative to the lower housing 18, for example, if the mobile work trolley 10 is turning. The wheel housing 34 is fixedly coupled to the lower housing 18 such that the axis of rotation of the wheels 28 remains perpendicular to the length of the mobile work trolley 10 and parallel to the width of the mobile work trolley 10.

[0090] The mobile work trolley 10 includes one or more mounting locations (shown as coupling interfaces 80) along the edge of a frame (e.g., upper housing 12) that are coupled to a modular storage unit 56. Figures 2 to 3 In various embodiments, one or more connection interfaces 80 are positioned around the periphery 32 of the upper housing 12. In a particular embodiment, the mounting location is compatible with the connection mechanism described in International Patent Application No. PCT / US 2018 / 044629, which is incorporated herein by reference in its entirety. In various embodiments, one or more connection interfaces 80 include a first rib 82 and a second rib 82 extending along opposite sides of the connection interface 80, the first rib 82 and the second rib 82 being offset from the upper housing 12, and the connection interface 80 is configured to engage with a second connection interface including two tongues (the two tongues extending from the second connection interface in opposite directions), for example, via two ribs of the connection interface 80 to two tongues of the second connection interface. It is envisioned herein that boxes, hooks, bags, batteries, accessories, etc., can be attached to the mounting location. In various embodiments, the connection interface 80 is configured to engage with a tool storage modular unit such that the tool storage modular unit is supported by the upper housing 12.

[0091] Handle 90 is attached to the mobile work cart 10, for example, detachably attached to the mobile work cart 10 (e.g., via connection interface 80). In various embodiments, handle 90 is configured to facilitate user movement of the mobile work cart 10. In a specific embodiment, handle 90 is removably attached to a first end 22 (e.g., “rear”) of the upper housing 12 and / or to a second end 24 (e.g., “front”) of the upper housing 12 opposite to the first end 22, allowing the user to position handle 90 such that the front or rear wheels turn when the user pushes the mobile work cart 10 around the construction site.

[0092] In a specific embodiment, the support leg 26 includes one or more recessed portions (e.g., recesses shown as grooves 40). In a specific embodiment, groove 40 is J-shaped. In use, groove 40 receives axle 54. Rolls of objects (e.g., coils of wire) are suspended around axle 54. These rolls are allowed to rotate around axle 54 and axle 54 is allowed to rotate within groove 40, thereby allowing easy removal of wire from the rolls.

[0093] refer to Figure 5 The groove 40 includes an upper portion 42 extending inwardly from the outer surface 36 of the leg 26. The groove 40 is configured to receive the axle and allow rotation of the axle. A retaining region 44 extends from the upper portion 42 in a downward direction 46 and is configured to receive the axle 54 and allow rotation of the axle within the retaining region 44. In a specific embodiment, a protrusion 48 extends in a direction 50 into the groove 40 above the retaining region 44, thereby helping to secure the axle 54 within the retaining region 44. In a specific embodiment, the upper portion 42 extends inwardly from the outer surface 36 of the leg 26 in a first direction 50 and extends toward the lower housing 18 in a downward direction 46.

[0094] refer to Figures 6 to 10Various aspects of mobile work trolleys 10, 110, 120, and 130 are shown. Mobile work trolley 110 is similar to mobile work trolley 10, except for the differences described. In various embodiments, mobile work trolley 110 has a length of 44” and a width of 21”. Mobile work trolley 120 is similar to mobile work trolleys 10 and 110, except for the differences described. In various embodiments, mobile work trolley 120 has a length of 44” and a width of 19”. Mobile work trolley 130 is similar to mobile work trolleys 10, 110, and 120, except for the differences described. In various embodiments, mobile work trolley 130 has a length of 44” and a width of 24”. In various embodiments, the mobile work trolley described herein has a width between 17.38” and 19.5” or between 25” and 26.5”.

[0095] In a specific embodiment, the mobile work trolley 10 has a width of 21” 16” and a length of 56” 14”. In a specific embodiment, the mobile work trolley 110 has a width of 19” and a length of 44”. In a specific embodiment, the mobile work trolley 210 has a width of 24” and a length of 44”. In an alternative embodiment, the mobile storage devices have an arrangement similar to that of the mobile work trolley 210, except that each of these storage devices is arranged parallel to the length of the mobile storage device rather than perpendicular to the length of the mobile storage device, and therefore the mobile storage devices are longer than the mobile work trolley 210. In a specific embodiment, the lower housing of the mobile work trolley 130 extends beyond the front surface of the upper housing. Figure 10 ).

[0096] refer to Figures 11 to 19 The mobile work trolley 10 includes a locking device (shown as a support leg 60). The support leg 60 is actuated between a locked position and an unlocked position. In the locked position, the support leg 60 abuts against the floor on which the mobile work trolley 10 is positioned, thereby biasing the mobile work trolley 10 to keep it stationary. This stationary positioning of the mobile storage device can be useful, for example, when pulling wire from a roll. The wheels 28 extend a distance 70 from the lower surface 20 of the lower housing 18, a distance less than the distance 68 from which the protrusion 66 extends from the lower surface 20 of the lower housing 18. Because the protrusion 66 extends further from the lower surface 20 than the wheels 28, the wheels 28 are no longer in contact with the floor when the support leg 60 is in the locked position.

[0097] The support bracket 60 includes a body 62 that extends laterally along the body of the lower housing 18. Two protrusions 66 are attached to opposite ends of the body 62, and a mating portion (shown as protrusion 64) is attached to the central portion of the body 62.

[0098] The support leg 60 rotates about axis 72 relative to the lower housing 18. The support leg 60 rotates in direction 74 to move from the locked position. Figures 11 to 12 Actuate to the unlock position ( Figures 13 to 14 ).

[0099] refer to Figures 15 to 16 To rotate the support 60 from the unlocked position to the locked position, the user extends their foot to engage with the protrusion 64. Figure 15 The user rotates the protrusion 64 in the opposite direction to direction 74 to actuate the support leg from the unlocked position to the locked position. Figure 16 ). Figures 17 to 19 An exemplary process is shown for reversing the process and actuating the support 60 from the locked position to the unlocked position.

[0100] refer to Figures 20 to 51 The container, unit, and / or device (shown as mobile storage device 310) are illustrated. Except for the differences discussed herein, mobile storage device 310 is substantially the same as mobile work cart 10.

[0101] The portable storage device 310 includes coupling assemblies 312 and 313 coupled to a leg 389. The leg 389 extends between a lower housing 386 and an upper housing 388. The upper housing 388 includes one or more couplings 318 extending around the upper housing 388. In a specific embodiment, the couplings are compatible with the coupling mechanism described in International Patent Application No. PCT / US 2018 / 044629, which is incorporated herein by reference in its entirety. References Figure 20 In various embodiments, a unit (e.g., a modular storage unit) is coupled to the bottom of an upper housing, the modular storage unit including one or more coupling mechanisms (shown as male connector 321). Male connector 321 includes two tongues extending from male connector 321 and configured to engage with other coupling mechanisms (e.g., coupling interface 80). Reference Figures 22 to 26 Modular storage units 397 and 398 are detachably connected to connectors 318 arranged on the upper housing 388.

[0102] refer to Figures 27 to 38The diagram illustrates various aspects of the connecting assembly 312. The connecting assembly 312 includes a connecting element 320 connected to a leg (e.g., a first leg of a plurality of legs), and a connecting element 360 connected to different legs. As will be described in more detail below, connecting elements 320 and 360 are each configured to receive an elongated support structure (e.g., a cylinder).

[0103] refer to Figures 29 to 31 The connecting element 320 includes a lower wall 322 that extends laterally across the bottom of the connecting element 320. A rear wall 324 extends upward from the lower wall 322 away from the lower housing 386, for example, extending vertically upward.

[0104] As will be described in more detail below, the connecting element 320 receives a cylindrical object (e.g., a tube). The cylindrical object may be arranged within the connecting element 320 in two or more locations (shown as a main channel 326 and an angled channel 340). The main channel 326 extends along a first axis 327, and the angled channel 340 extends along a second axis 341. The main channel 326 extends through the connecting element 320 from the front portion 332 furthest from the rear wall 324, through the middle portion 334, and reaches the rear portion 336 near the rear wall 324. In a specific embodiment, the main channel 326 extends horizontally. The main channel 326 also extends vertically from the lower portion 330 near the lower wall 322 to the upper portion 328.

[0105] An angled channel 340 extends from the front portion 342 furthest from the rear wall 324 through the connecting element 320, through the intermediate portion 344, and reaches the rear portion 346 near the rear wall 324 and the orifice 338. In a specific embodiment, the angled channel 340 extends horizontally. The front portion 342 of the angled channel 340 is displaced relative to the front portion 332 of the main channel 326 in a first direction 348. The rear portion 346 of the angled channel 340 is displaced relative to the rear portion 336 of the main channel 326 in a second direction 350 opposite to the first direction 348. The front portion 342 of the angled channel 340 is separated from the front portion 332 of the main channel 326 by a protrusion 358. In various embodiments, the protrusion 358 extends upward from the lower wall 322 between the main channel 326 and the angled channel 340. Reference Figure 31For illustrative purposes, exemplary embodiments of the main channel 326 and the angled channel 340 are depicted by large dashed lines with arrows. The angled channel 340 extends through the main channel 326 at an angle 359, for example, when viewed from above (e.g., from a top angle, the angled channel 340 defines an angle 359 relative to the main channel 326). In specific embodiments, the angle 359 is at least 30 degrees, and more specifically between 30 and 60 degrees, and more specifically between 40 and 50 degrees, and more specifically 45 degrees. In various embodiments, the angle 359 is at least 30 degrees and less than 60 degrees. In various embodiments, the angled channel 340 extends horizontally relative to the floor on which a movable tool support is positioned.

[0106] In a specific embodiment, the main channel 326 is aligned with at least a portion of the rear wall 324, thereby preventing the elongated support structure from extending beyond the rear wall 324 as it passes through the main channel along the first axis 327. In a specific embodiment, the angled channel 340 is aligned with and extends through the orifice 338, thereby allowing the elongated support structure to extend beyond the rear wall 324 as it passes through the angled channel 340 along the second axis 341. The main channel 326 is in fluid communication with the orifice 338 via the angled channel 340. In a specific embodiment, the middle portion 344 of the angled channel 340 and the middle portion 334 of the main channel 326 are co-extended.

[0107] refer to Figures 32 to 38 An exemplary method for loading a device (shown as a wire coil 395) onto a cylinder 314 coupled to a coupling assembly 312 is described. In use, the wire coil 395 is permitted to rotate relative to the cylinder 314, thereby allowing the wire on the wire coil 395 to be dispensed.

[0108] exist Figure 33 Starting from point 352, the end 352 of the cylindrical object 314 is pivoted away from the movable storage device 310 in the upward direction 354 and the outward direction 356. The cylindrical object 314 is positioned in the angled channel 340 and inserted through the orifice 338. Figure 35 In this position, the cylinder 314 can rest within the connecting element 320, so that the cylinder 314 does not need to be supported by the user. The user then slides the supply (shown as a coil of wire 395) onto the cylinder 314. Figure 36 The end 352 of the cylindrical object 314 is pivoted back toward the connecting element 360. Figure 37 The cylinder 314 is then inserted into the connecting element 360, thereby providing tactile and / or auditory indication that the cylinder 314 is secured within the connecting element 360. The connecting element 360 is described in more detail below.

[0109] refer to Figures 39 to 47 The diagram illustrates various aspects of the connecting assembly 313. The connecting assembly 313 includes a connecting element 360 connected to a first leg and a second connecting element (shown as a pivot hinge 380) connected to a second leg different from the first leg. A cylinder 316 extends between the connecting element 360 and the hinge 380.

[0110] refer to Figures 40 to 41 The connecting element 360 includes a main channel 362 extending vertically through the connecting element 360. Side portions 364 of the main channel 362 define a lateral periphery of the main channel 362. In various embodiments, the connecting element 360 is configured to receive an elongated support structure when the elongated support structure extends along a first axis 327 through the main channel 326 of the first connecting element 320.

[0111] Recess 365 receives a biasing element (shown as spring 366). When the cylinder passes over spring 366, through upper portion 368, and inserts into lower portion 370, spring 366 produces an audible click and / or tactile vibration, indicating that the cylinder is within lower portion 370 of connecting element 360. Spring 366 biases the cylinder to prevent it from entering and exiting lower portion 370 of main channel 362. In a specific embodiment, spring 366 is symmetrically arranged on either side of main channel 362.

[0112] refer to Figures 42 to 47 An exemplary method for loading a device (shown as a coil of wire 395) onto a cylindrical object 316 coupled to a coupling assembly 313 is described.

[0115] In a specific embodiment, the orifice 393 in the second leg 392 is vertically offset and slightly lower than the corresponding orifice 391 in the first leg 390. As a result, when a tool (shown as a conduit bender 396) is inserted through orifice 391 and then orifice 393, the conduit bender 396 ( Figure 49 The slightly angled positioning helps secure the catheter bender 396 within the leg 389 of the movable storage device 310. Alternatively, the catheter bender 396 can be inserted between the upper housing and the handle 319, such that the lower end of the catheter bender 396 rests within the retaining device (shown as container 394).

[0116] refer to Figure 52 The diagram illustrates a container, unit, and / or device (shown as mobile storage device 410). Except for the differences discussed herein, mobile storage device 410 is substantially the same as mobile storage device 310. In a particular embodiment, mobile storage device 410 receives a plurality of cylindrical objects through openings in the legs, for example, receiving three cylindrical objects through a pair of legs.

[0117] refer to Figures 53 to 58 A portion of the container, unit, and / or device (shown as part of mobile storage device 510) is illustrated. Except for the differences discussed herein, mobile storage device 510 is substantially identical to mobile storage device 310. Although in Figure 53 Only one support leg 514 is shown attached to the housing 512, but it will be understood that various embodiments of the mobile storage device 510 each include one or more support legs 514, such as four support legs 514.

[0118] The mobile storage device 510 includes one or more wheel housings 516 attached to the bottom of the lower housing 512. One or more support legs 514 are attached to the top of the lower housing and extend upward away from the wheel housings 516. A support structure (shown as a bracket 540) reinforces the connection where the support legs 514, wheel housings 516, and lower housing 512 are joined.

[0119] refer to Figure 55 The lower housing 512 receives the bracket 540 in the recess 522. The lower housing 512 includes one or more openings 526 through which fasteners extend to engage with the wheel housing 516. The lower housing 512 also includes one or more openings 524 through which fasteners extend to engage with the support leg 514.

[0120] refer to Figure 56The bracket 540 includes a lower panel 542 defining one or more openings 550. In a specific embodiment, fasteners extend through the openings 550 to attach the bracket 540 to the wheel housing 516. A first side panel 544 and a second side panel 546 extend upward from the lower panel 542 and each defines one or more openings 548. In a specific embodiment, fasteners extend through the openings 548 to attach the bracket 540 to the support leg 514.

[0121] refer to Figures 57 to 58 Support leg 514 is positioned between bracket 540 and lower housing 512. In a specific embodiment, support leg 514 is formed of plastic material. Fasteners (shown as bolts) extend through openings to connect support leg 514, lower housing 512, bracket 540, and wheel housing 516. The applicant has observed that providing bracket 540 at one or more corners of lower housing 512 improves the strength of mobile storage device 510 and thereby reduces the likelihood of structural failure of mobile storage device 510 at that location.

[0122] refer to Figures 59 to 63 The container, unit, and / or device (shown as mobile storage device 610) are illustrated. Except for the differences discussed herein, mobile storage device 610 is substantially the same as mobile storage device 510.

[0123] The mobile storage device 610 includes an arrangement of orifices for facilitating the storage of a long tool (shown as a conduit bender 630). For example, the handle 632 of the conduit bender 630 extends through these orifices. The conduit bender 630 rests within these orifices at a slightly elevated angle, such that gravity biases the conduit bender 630 to hold it within the mobile storage device 610.

[0124] In various embodiments, a first opening 640 is defined by a first support leg, and a second opening 670 is defined by a second support leg. As will be described, the first opening 640 and the second opening 670 are arranged at positions (e.g., heights) that are equal or approximately equal to each other. The different rates of width variation of the first opening 640 and the second opening 670 cause the elongated tool to rest at different heights within the first opening 640 and the second opening 670. For example, refer to... Figure 59 The handle 632 of the conduit bender 630 rests in a lower position within the first orifice 640 than within the second orifice 670. As a result, gravity biases the conduit bender 630 to keep it within the movable storage device 610.

[0125] The portable storage device 610 includes a lower housing 612. The lower housing 612 defines a main longitudinal axis 614 along which the lower housing extends, and a lateral axis 616 perpendicular to axis 614. One or more support legs 620 extend upward from the lower housing 612, including a first support leg 626 and a second support leg 628. Figure 59 As observed by the lieutenant general, the support leg 620 is arranged around the lower housing 612 such that the first orifice 640 and the second orifice 670 are aligned with each other along axis 614 or axis 616.

[0126] refer to Figures 60 to 63 Each support leg 620 includes a first wall 622 and a second wall 624. In a specific embodiment, the first wall 622 and the second wall 624 are perpendicular to each other. The first wall 622 includes one or more first openings 640, and the second wall 624 includes a second opening 670. As will be described, the first openings 640 and the second openings 670 provide widths that vary at different rates, thereby allowing the tool handle to rest at different heights for a range of tool handle diameters.

[0127] refer to Figures 61 to 62 The sidewall 646 of the first aperture 640 defines a width that changes from a maximum width portion 644 to a shorter width. The first aperture 640 defines a minimum width portion 650 at the transition from the linear sidewall 646 of the first aperture 640 to the curved end 648. In a specific embodiment, the end 648 of the first aperture 640 defines a curved portion, such as a semicircle.

[0128] The sidewall 676 of the second aperture 670 defines a width that changes from the maximum width portion 674 to a shorter width. The second aperture 670 defines a minimum width portion 680 at the transition from the linear sidewall 676 of the second aperture 670 to the curved end 678. In a specific embodiment, the end 678 of the second aperture 670 defines a curved portion, such as a semicircle.

[0129] A first aperture 640 defines an upper end 662, a lower end 648, and a sidewall 646 extending between the upper end 662 and the lower end 648. The first aperture 640 defines a first maximum width portion 644 at the transition from the upper end 662 to the sidewall 646, and a first minimum width portion 650 at the transition from the lower end 648 to the sidewall 646. The first aperture 640 defines a width that changes from the first maximum width portion 644 to the first minimum width portion 650 at a first rate. In various embodiments, the upper end 662 and the lower end 648 of the first aperture 640 are arc-shaped.

[0130] The second aperture 670 is aligned with the first aperture 640 such that the first aperture 640 and the second aperture 670 are configured to simultaneously receive an elongated support structure extending between the first aperture 640 and the second aperture 670. In various embodiments, the first aperture 640 and the second aperture 670 are configured such that the elongated support structure is oriented at a non-zero angle relative to the horizontal line when it extends between the first aperture 640 and the second aperture 670, and in particular, gravity biases the elongated support structure to keep it within the first aperture 640 and the second aperture 670 (e.g., by gravity biasing the handle of the elongated support structure toward the apertures 640, 670).

[0131] The second aperture 670 defines an upper end 692, a lower end 678, and a sidewall 676 extending between the upper end 692 and the lower end 678. The second aperture 670 defines a first maximum width portion 674 at the transition from the upper end 692 to the sidewall 676, and a first minimum width portion 680 at the transition from the lower end 678 to the sidewall 676. The second aperture 670 defines a width that changes from the first maximum width portion 674 to the first minimum width portion 680 at a first rate. In various embodiments, the upper end 692 and the lower end 678 of the second aperture 670 are arc-shaped.

[0132] The width of the first aperture 640 changes from a maximum width portion 644 to a minimum width portion 650 at a first rate spanning a length 652. The width of the second aperture 670 changes from a maximum width portion 674 to a minimum width portion 680 at a second rate spanning a length 682, and the second rate is less than the first rate. In other words, the first aperture 640 narrows faster than the second aperture 670.

[0133] In a specific embodiment, the first rate and the second rate are each width changes relative to the height change, and the ratio of the first rate to the second rate is between 2.5:1 and 1.1:1, and more specifically between 2.0:1 and 1.3:1, and more specifically 1.6:1. In a specific embodiment, the total length 642 of the first aperture 640, as measured in the vertical direction, is less than the total length 672 of the second aperture 670.

[0134] refer to Figure 63The first opening 640 defines a first height 654 for the maximum width portion 644 and a second height 656 for the minimum width portion 650. The second opening 670 defines a first height 684 for the maximum width portion 674 and a second height 686 for the minimum width portion 680. The bottom of the first opening 640 is higher than a given position on the support leg 620 by a height 660, and the bottom of the second opening 670 is higher than the same position on the support leg 620 by a height 690. In a specific embodiment, height 660 is equal to height 690 because the bottoms of the first opening 640 and the second opening 670 are at the same height. In a specific embodiment, the height 656 of the minimum width portion 650 of the first opening 640 is equal to or approximately equal to the height 686 of the minimum width portion 680 of the second opening 670.
