Great Britain patent number 2 215 585 granted to Nierhaus, outlines the use of a kneepad having a lower portion, which is substantially cylindrical, for abutment with the upper end of the shinbone of the wearer, and an upper portion, which is in the form of a sector of a sphere, substantially for abutment with the kneecap of the wearer. There is also a retaining strap engaging with the lower lateral edge of the lower portion and going around the leg of the wearer, rather than the popliteal space immediately behind the knee.

Although each of the inventions outlined in the previously discussed patents are novel and useful, most do not comfortably support the knee and lower shin while in use. Specifically, there is a problem with current rolling kneepad caster assemblies and that they can be uncomfortable for the user. A kneepad that transfers weight to a shin support rather than a strap, would be more comfortable for a given user and would be of benefit to those that must use a kneepad or “creeper” type of device.

None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.

SUMMARY OF THE INVENTION

The invention is a rolling kneepad caster device. The rolling kneepad caster device has a multiple wheeled support assembly with swivel casters to provide structure to the improved rolling kneepad caster device to support a user, a kneepad cushion provided above the three wheeled support assembly to comfortably receive a user's knee, a substantially elongated shin guard adjacently attached to the multiple wheeled support assembly, the substantially elongated shin guard having cushioning provided to comfortably receive a user's shin and upper foot and a plurality of strap fasteners to secure the user's knees and shins to the rolling kneepad caster device.

Accordingly, it is a principal object of the invention to provide a rolling kneepad caster device with a shin guard that is more comfortable to wear than current rolling kneepads with shin guards.

It is another object of the invention to provide a rolling kneepad caster device with a shin guard that prevents any straps from binding to a user's legs by carrying the device's weight when the user walks, preventing manual repositioning.

It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.

It is a further object of the invention to provide a rolling kneepad caster device that supports the device's weight by a shin guard that transfers the device's weight to the top of the foot instead of the leg and ankle straps provided in the back of the rolling kneepad caster device.

These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is a rolling [0030] kneepad caster device 10 used by a user U, as is shown in FIG. 1.
The rolling [0031] kneepad caster device 10 comprises a multiple wheeled support assembly 20 with swivel casters 22 to provide structure to the rolling kneepad caster device 10 to support a user U, a kneepad cushion 30 provided above the multiple wheeled support assembly 20 to comfortably receive a user's knee, a substantially elongated shin guard 40 adjacently attached to the multiple wheeled support assembly 20, the substantially elongated shin guard 40 having cushioning 42 provided to comfortably receive a user's shin and upper foot and a plurality of strap fasteners 50 to secure the user's knees and shins to the rolling kneepad caster device 10.
As is shown in FIG. 2 and FIG. 3, the multiple [0032] wheeled support 20 and the substantially elongated shin guard 40 are both provided with kneepad cushioning 30 and shin guard cushioning 42. The multiple wheeled support 20 has 3 swivel casters 22, which are equally spaced apart, independently movable and can turn and roll in any direction desired by the user U. The multiple wheeled support 20 allows a user U to move in any direction by the user U shifting his or her weight and pushing off against the ground with the top of their feet and toes.
The [0033] kneepad cushion 30 is ergonomically designed to receive a user's U knee, as depicted with a generally depressed middle portion 32 and raised perimeter portion 34. The substantially elongated shin guard 40 and cushioning 42 is concaved downward to also ergonomically receive a user's U shin and upper foot. The height of the multi-wheeled support 20 is greater than the concavity from the substantially elongated shin guard 40 to allow the rolling kneepad caster device 10 from scraping against the ground. The distal end of the substantially elongated shin guard 44 terminates in such a way as to allow a user's U foot to hang-off of the distal end of the substantially elongated shin guard 44 to allow for the user to push-off of the ground to propel himself along the ground. The distal end of the substantially elongated shin guard 44 serves as a cushion to comfortably handle the device's weight being transferred from the plurality of strap fasteners 50.
Several devices in the related art have substantially elongated shin guards provided as part of a rolling kneepad caster device. U.S. Pat. No. 2,448,427 issued to Gordon, U.S. Pat. No. 5,380,021 issued to Doherty and U.S. Pat. No. 5,427,391 issued to Cooper outline similar rolling kneepad caster devices that include substantially elongated shin guards. These similar rolling kneepad caster devices, however have their shortcomings. The pair of individual knee and shin provisions are joined together and are not independently separate to allow for greater mobility with the devices outlined in the Gordon patent and the Doherty patent. The kneepads taught in U.S. Pat. No. 5,427,391 issued to Cooper also utilize shin guards, but are not padded and do not enable a user to use the top of his or her feet to propel themselves on the ground. The rolling [0034] kneepad caster device 10 outlined in this application provides greater comfort and greater maneuverability for a user U then the devices outlined in these other patents. Also users may easily stand and walk, and kneel again without manually readjusting the rolling kneepad caster devices 10.
FIG. 4 also depicts the rolling [0035] kneepad caster device 10. Both the multiple-wheeled support 20 and the substantially elongated shin guard 40 are cushioned with a kneepad cushion 30 and shin guard cushioning 42 that is made of soft foam rubber material or gelatinous material. A plurality of fastening straps 50 are provided to be placed over the multiple-wheeled support 20 as well as the substantially elongated shin guard 40. The plurality of strap fasteners 50 are secured using hook and loop fasteners (not shown) that are well known in the related art. The plurality of strap fasteners 50 are made of nylon and have hook and loop fasteners provided on the ends of the plurality of strap fasteners 50.
Use of the rolling [0036] kneepad caster device 10 is uncomplicated. A typical user will attach the rolling kneepad caster device 10 manually to each of his or her knees and shins, allowing for the top of their feet to push off of the ground and propel themselves with. The plurality of strap fasteners 50 are self-adjusting and are one-size fits all. As previously noted, the swivel casters 22 from the multiple-wheeled support 20 move independently from each other and can maneuver and roll in any direction. Users can also easily manually remove the rolling kneepad caster device 10 from their knees and shins. The rolling kneepad caster device 10 is approximately 2.5′ long and 8.0″ wide at the multiple-wheeled support 20.
It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims. [0037]
