EXEMPLARY EMBODIMENTS

FIGS. 1-8 show various aspects of an exemplary embodiment of the kneepad assembly of the present invention generally designated 10. Kneepad assembly knee pad system 10 includes an outer knee pad structure, generally designated 12; a knee cap support spring, generally designated 14; and a resilient foam inner knee and shin pad structure, generally designated 16.

Outer knee pad structure 12 being molded of plastic and including a bottom knee support plate, generally designated 18, having a non-slip bottom surface 20 and a top portion 22 integrally formed with a knee and shin receiving structure, generally designated 24, that defines an inner knee and shin pad receiving channel 28. Inner knee and shin pad receiving channel 28 is partially defined by a bottom channel surface 30 of knee and shin receiving structure 24 that has a number of impact absorbing cavities 32 and a spring bottom receiving channel 34 provided therein. Inner knee and shin pad receiving channel 28 is also partially defined by an accordion fold portion, generally designated 36 extending upwardly from a front end 40 of the bottom channel surface 30 and a pair of mirror image side wall assemblies, generally designated 48, 50 each extending from an opposite side edge 52, 54 of bottom channel surface 30 and each including along a rear top sidewall edge thereof a kneepad assembly retaining strap aperture 56 for receiving a securing strap 58 for retaining the rear portion of outer knee pad structure 12 adjacent to an upper shin of a user.

The accordion fold portion 36 includes a number of semi-circular accordion folds 51 and two spaced retaining strap apertures 60. Each of the two spaced retaining strap apertures 60 is provided for receiving a retaining strap 58 for retaining the accordion fold portion 36 of outer knee pad structure 12 adjacent to a knee of a user.

The resilient foam inner knee and shin pad structure 16 is shaped to seat into the inner knee and shin pad receiving channel 28 of the knee and shin receiving structure 12 and includes a top spring receiving channel 66 for receiving a top end 70 of knee cap support spring 14 when a bottom end 72 of knee cap support spring 14 is positioned within spring bottom receiving channel 34 of bottom channel surface 30.

FIG. 9 shows a second exemplary embodiment of the outer knee pad structure, generally designated 12a, that has a smooth bottom channel surface 30a that does not have the impact absorbing cavities 32 of outer knee pad structure 12.

In use, the user may use knee pad assembly 10 with or without knee cap support spring 14 or resilient foam inner knee and shin pad structure 16. Knee cap support spring 14 may be used alone with outer knee pad structure 12 or 12a. Also, if desired, resilient foam inner knee and shin pad structure 16 may be used alone with outer knee pad structure 12 or 12a by directly inserting resilient foam inner knee and shin pad structure 16 into inner knee and shin pad receiving channel 28 without any knee cap support spring 14. Additionally, two knee pad assemblies 10 may be used, one for each knee of the worker.

It is noted that the embodiment of the kneepad assembly knee pads system described herein in detail for exemplary purposes is of course subject to many different variations in structure, design, application and methodology. Because many varying and different embodiments may be made within the scope of the inventive concept(s) herein taught, and because many modifications may be made in the embodiment herein detailed in accordance with the descriptive requirements of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
