In such embodiments, the step of attaching the skid plate to the telescoping handle can also include engaging one of the attachment members with the telescoping base proximate to a bottom side of the upper handle mount, engaging another of the attachment members with the telescoping base proximate to a top side of the lower handle mount, and enclosing at least a portion of the lower handle mount with the cover body.
These and other features, objects and advantages of the present invention will become more apparent to one skilled in the art from the following description and claims when read in light of the accompanying drawings.
As shown in
As used herein, the terms “upper,” “lower,” “bottom” and other terms of orientation refer the sides, ends or direction of the rolling container and/or skid plate when the container rests on its bottom support 23 with the skid plate 100 in a vertical orientation as depicted in
As shown in
The telescoping handle 40 can include at least one telescoping base 45, at least one telescoping element 47 configured to retract within said telescoping base 45, and a handle 41 coupled to the at least one telescoping element 47. The handle 41 can also be coupled to a pair of telescoping bases 45 and a pair of telescoping elements 47. The telescoping handle 40 can also include a plurality of nested, telescoping elements 47 configured to retract within the telescoping base 45.
In one embodiment, the telescoping handle 40 can be attached to the container body 20 with at least one handle mount 50, 51. In other embodiments, the telescoping handle 40 can be attached to the container body 20 with a lower handle mount 50 and an upper handle mount 51. The lower handle mount 50 can be attached to a lower portion of the container body 20, such as a lower portion of the back support 25. The upper handle mount 51 can be attached to an upper portion of the container body 20, such as an upper portion of the back support 25. The handle mounts 50, 51 can secure the telescoping base 45 of the telescoping handle 40.
Because the telescoping elements 47 of the telescoping handle 40 retract and nest within the telescoping base 45, deformation or other damage to the telescoping base 45 can impede the functioning of the telescoping handle 40. For example, if the telescoping base 45 is dented or bent, the telescoping elements 47 may no longer extend/retract properly or may no longer fit within the telescoping base 45. The skid plate 100 described herein enables users to drag the container over impediments, such as curbs and stairs, without damaging relevant portions of the telescoping base 45 and telescoping elements 47.
As shown in
The cover body 115 can extend the length of the telescoping base 45 or a portion of the length of the telescoping base 45. For example, when the telescoping base 45 is secured with handle mounts 50, 51, the cover body 115 can extend from the upper handle mount 51 to the lower handle mount 50 or between the upper handle mount 51 and the lower handle mount 50. The cover body 115 can also extend from a bottom side of the upper handle mount 51 to a bottom side of the lower handle mount 50. When the telescoping base 45 extends below the lower handle mount 50, the cover body 115 can also extend from a bottom side of the upper handle mount 51 to a bottom side of the telescoping base 45.
The cover body 115 can define first and second vertical edges 162, 163, and the vertical edges 162, 163 can rest against or proximate the back support 25 of the container body 20 when enclosing portions of the telescoping base 45. The cover body 115 can also enclose portions of one or both of the handle mounts 50, 51. In one arrangement, the cover body 115 can also include notches 160 in the first and second sidewall sections for receiving portions of the handle mount 50, as shown in
These features of the cover body 115 can provide a close and secure fit for maximized protection of the telescoping base 45.
The cover body 115 can be formed from or include suitable durable materials for protecting a telescoping handle from damage. For example, the cover body 115 can include metals such as steel and aluminum, thermoplastics such as high-density polyethylene (HDPE) and ultra-high-molecular-weight polyethylene (UHMWPE), and other polymers.
The cover body 115 includes an inner side. The inner side of the cover body 115 is shown in
The skid plate 100 can also include engagement members 120, 130 extending from the inner side of the cover body 115 for engaging with the telescoping base 45 of the telescoping handle 40. Engagement members can include clips, prongs, clamps, straps, belts, rings, bolts, screws, rivets and magnets. The engagement members 141-146 can be coupled to the inner side of the cover body 115 on the first and second sidewall sections 117, 118, on the back section 116, or both. Coupling to the inner side of the cover body 115 can include direct attachment to the inner side, such as engagement members 141-146 extending directly from the inner surface (for example, as shown in
In one embodiment, the skid plate 100 can include one engagement member (e.g., 141 or 142). In other embodiments, the skid plate 100 can include a plurality of engagement members (e.g., 141-146) extending from the inner side of the cover body 115.
The plurality of engagement members 141-146 can include at least one attachment member 142, 144, 146 for securing the cover body 115 to the telescoping base 45. The plurality of engagement members 141-146 can also include at least one spacing member 141, 143, 145 for providing a space between the telescoping base 45 and the back section 116 of the inner side of the cover body 115.
As shown in
The spacing members 141, 143, 145 can be vertically spaced apart from the attachment members 142, 1441, 146 as shown in
Spacing members can also be coupled to attachment members. For example as shown in
In another embodiment shown in
In another embodiment shown in
In another embodiment, the engagement members 142, 144, 146 can include other fasteners such as bolts or screws for engaging with the telescoping base 45 to attach the skid plate 100 to the telescoping handle 40.
The engagement members can also engage with the telescoping base to form a slope relative to the cover body 115. For example, as shown in
The slope can be formed based on engagement members having a smaller elevation proximate the upper end of the skip plate 100 and progressively larger elevations toward the lower end of the skid plate 100. For example as shown in FIG. 5, the engagement members can include a first clip 141/142, a second clip 143/144 and a third clip 145/146. The second clip 143/144 can be disposed below the first clip 141/142, and the third clip 145/146 can be disposed below the second clip 143/144. The first clip base 141 can be coextensive with the back section 116 of the cover body 115, i.e. an elevation of zero. The second clip base 143 and the third clip base 145 can have elevations greater than zero, with the third clip base 145 extending from the cover body 115 further, i.e. at an elevation greater than, the second clip base 145.
The slope can also be formed by varying a thickness of the inner side of the cover body 115, as shown in
When the telescoping base 45 is secured with handle mounts 50, 51, the slope in the skid plate 100 can allow at least a portion of a handle mount 50, 51 to be enclosed and protected while also providing a relatively level outer surface of the skid plate 100 to facilitate dragging the container 10 by the handle 40 over impediments. For example, the slope can approximate the change in elevation from the telescoping base 45 to the handle mount 50.
A method of protecting a telescoping handle 40 is also described herein. The method can include the steps of providing a telescoping handle 40 with a telescoping base 45, providing a skid plate 100, and attaching the skid plate 100 to the telescoping handle 40. The skid plate 100 can include a cover body 115 including a back section 116, a first sidewall section 117 and a second sidewall section 118. The cover body 115 can define a concave cavity to enclose therein portions of the telescoping base 45. The skid plate 100 can be attached such that an inner side of the cover body 115 engages with the telescoping base 45.
The skid plate 100 can be attached to the telescoping handle 40 in any suitable way, including without limitation adhesives, welding, and engagement members. When the skid plate 100 includes a plurality of engagement members 141-146 extending from the inner side of the cover body 115, the step of attaching the skid plate 100 to the telescoping handle 40 can also include engaging the plurality of engagement members 141-146 with the telescoping base 45.
When the telescoping base 45 is secured with upper and lower handle mounts 50, 51, the step of attaching the skid plate 100 to the telescoping handle 40 can also include attaching the skid plate 100 below the upper handle mount 51 and enclosing at least a portion of the lower handle mount 50. The plurality of engagement members 141-146 can also include at least two attachment members 142, 144, 146 and at least one spacing member 141, 143, 145. The step of attaching the skid plate 100 to the telescoping handle 40 can also include engaging one of the attachment members 142, 144, 146 with the telescoping base 45 proximate a bottom side of the upper handle mount 51, engaging another of the attachment members 142, 144, 146 with the telescoping base 45 proximate to a top side of the lower handle mount 50, and enclosing at least a portion of the lower handle mount 50 with the cover body 115. The at least one spacing member 141, 143, 145 can provide a space between the telescoping base 45 and the container 10 and forms a slope to accommodate enclosing at least a portion of the lower handle mount 50 with the cover body 115.
Accordingly, a rolling container 10 can include a container body 20, at least one wheel 30, a telescoping handle 40, and a skid plate 100 as described herein. The rolling container 10 can also include a telescoping handle 40 with a pair of telescoping bases, and a skid plate 100 can be attached to each telescoping base 45.
The skid plate described herein provides a rolling container with exceptional durability, even when heavy loads are stored and transported in the container body. In one experiment, a rolling bag, such as shown in
