This application is a continuation of application Ser. No. 11/060,635, filed Feb. 17, 2005, which claims the benefit of U.S. Provisional Application Ser. No. 60/545,421, filed Feb. 17, 2004, which is incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention relates to a thigh protector, and more particularly to a thigh protector having a vibration resistance layer and an impact resistance layer. The present invention also relates to a thigh protector connected to a waist supported structure having at least one band for attachment of a tool carrier.
BACKGROUNDUser's of pneumatic tools often experience repeated impacts and vibrations from the tools. In some cases these impacts and/or vibrations can cause serious injury to the user. One example of a pneumatic tool is a pneumatic hammer (sometimes referred to as a jack hammer), a tool typically used to break apart concrete surfaces. Often when a user operates a pneumatic hammer, the tool repeatedly impacts and/or vibrates against the user's thighs, typically against an inner portion of the thighs. Hence, a need exists for a thigh protector to be worn for protection when operating a pneumatic tool.
A known method for protecting a user against the impact and vibration of a pneumatic hammer is to wrap a soft material, such as a T-shirt around the pneumatic hammer and taping the soft material thereto. Accordingly, a need also exists for an improved protection device for attachment to a pneumatic hammer.
User's of pneumatic tools often carry other tools on a waist supported structure. Some waist supported structures include police belts, military belts and construction utility belts. These belts include attachment means such as eyelets, hooks, and/or pockets for the attachment of tools or tool carriers. However, these attachment means often cause the belt to torque or sag from the wearer's waist when a heavy tool is attached to them. Accordingly, an improved waist supported structure is needed for the attachment of tool carriers and having thigh protectors attached thereto for protection during operation of pneumatic tools.
SUMMARY OF THE INVENTIONIn one embodiment, the present invention is a thigh protector that includes a reinforcement material; a vibration resistant material attached to a first side of the reinforcement material; and a impact resistant material attached to a second side of the reinforcing member.
In another embodiment, the impact resistant material of the above described thigh protector includes an impact resistant component that is formed to a preformed curvature to support the remainder of the thigh protector in the preformed curvature; and an outer surface of the vibration resistant material includes a plurality of strips and a plurality of grooves, forming a plurality of air pockets therebetween for increases vibration resistance.
In yet another embodiment, the present invention is a waist supported structure for mounting a tool carrier to carry tools at the waist of a wearer that includes an upper portion having an outwardly directed surface adjacent the waist of a wearer and at least one band portion attached at its opposite ends to the outwardly directed surface, such that the band is disposed substantially parallel to and facing the outwardly directed surface to define a slot therebetween. The waist supported structure also includes a tool carrier extending through the slot and releasably attached to the at least one band portion; a lower portion having an outwardly directed surface and an inwardly directed surface adjacent the thigh of a wearer; and at least one thigh protector attached to the lower portion. The thigh protector includes a vibration resistant material attached to the outwardly directed surface of the lower portion; and an impact resistant material attached to the inwardly directed surface of the lower portion.
In still another embodiment, the present invention is a protective boot for attachment to a pneumatic tool. The boot includes a body movable from an open position to a closed position to removably secure the boot in surrounding relation to a portion of a pneumatic tool; and a fastener connected to the body for securing the body in the closed position; wherein the body includes protective outer and inner covers disposed in surrounding relation to a cushioning material.
BRIEF DESCRIPTION OF THE DRAWINGSThese and other features and advantages of the present invention will be better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
In one embodiment, the present invention is directed to a thigh protector. The thigh protector is particularly useful when worn as protection during operation of a pneumatic tool, such as a pneumatic hammer, a paving breaker, a chipping hammer, a concrete vibrator, a rivet buster or a trench digger. In one embodiment, the thigh protector includes a vibration resistance layer and an impact resistance layer. In another embodiment, the thigh protector is connected to a waist supported structure having at least one band for attachment of a tool carrier. Such a waist supported structure is described in U.S. patent application Ser. No. 10/456,878, which is herein incorporated by reference. In yet another embodiment of the invention, the present invention is directed to a user protection device for attachment to a pneumatic tool, such as a pneumatic hammer.
A belt loop 18 is attached to the reinforcing member 16. The belt loop 18 allows the thigh protector 10 to be suspended from a user's belt 21 (as shown in
In one embodiment, the thigh protector 10 is curved to approximate the curvature of a typical user's thigh. In one embodiment, when the thigh protector 10 is worn by a user, the belt loop 18 of the thigh protector 10 is suspended from the belt 21 (as shown in
To secure the thigh protector 10 to the user's leg (as shown in
In one embodiment, the longitudinal axis 23 of the vibration resistant material 12 forms an acute angel a with the belt loop 18. This angular arrangement of the longitudinal axis 23 of the vibration resistant material 12 with respect to the belt loop 18 urges the vibration resistant material 12 towards the inner thigh of the user. This is particularly helpful when the thigh protector 10 is worn during the operation of a pneumatic hammer, since it is natural to many user's to allow a large portion of the pneumatic hammer's weight to bear against the user's inner thighs while operating the pneumatic hammer.
As mentioned above, in use the vibration resistant material 12 protects a user's thigh when a pneumatic tool is contacted thereagainst. A pneumatic tool, such as a pneumatic hammer imparts a large amount of vibration on the user. Bearing the pneumatic hammer against the vibration resistant material 12 lessens the vibration that is transferred or felt by the user. In one embodiment, the vibration resistant material 12 is composed of a flexible, compressible material, such as a rubber material. Preferably, the vibration resistant material 12 is formed by an injection molding processes.
As shown in
In one embodiment, at least some of the protruding strips 38 are oriented at an angle with respect to the horizontal position, such as an angle of approximately forty five degrees. Such an angled orientation lessens the likelihood of the pneumatic tool repeatedly catching a leading edge of the protruding strips 38 and instead urges the pneumatic tool to slide relative to the protruding strips 38.
Repeated vibration by the pneumatic tool against the vibration resistant material 12 imparts shearing forces on the vibration resistant material 12 that tend to tear the vibration resistant material 12. Attaching the vibration resistant material 12 to the reinforcing member 16 reinforces the vibration resistant material 12 and lessens the likelihood of tearing of the vibration resistant material 12. In one embodiment the reinforcing member 16 is composed of a leather material such as vegetable tanned leather.
In one embodiment, the vibration resistant material 12 is attached directly to the impact resistant material 14 without the intervening reinforcing member 16. In such an embodiment, to add structural strength the to vibration resistant material 12 and to avoid tearing of the vibration resistant material 12, reinforcement members, such as metal bars and/or wires, are integrally formed with the vibration resistant material 12.
In one embodiment, as shown in
In one embodiment, the covering 43 is composed of a nylon fabric, such as cordura; the impact resistant component 44 is composed of a polycarbonate material; the first cushioning component 46 is composed of a high density foam material or a high density bubble wrap material; and the second cushioning component 48 is composed of a meshed foam material, such as Dri-Lex® 1013, manufactured by the Faytex Corporation located in Weymouth, Mass.
In the depicted embodiment, the covering 43 warps around the impact resistant component 44; the first cushioning component 46; and the second cushioning component 48 and binds the components 44, 46 and 48 together by a stitching 54 that extends around a periphery of the second cushioning material 48 (see for example, the stitching 54 in
The impact resistant component 44 preferably is formed to a predetermined curvature. For example, in one embodiment, the impact resistant component 44 is formed from a polycarbonate material in a heat forming process to a predetermined curvature. Polycarbonate is a particularly useful material for use as the impact resistant component 44 because of its excellent shape memory properties. This property allows the material to return to its original shape when an external force displaces the material from its original shape. This property is advantageous because it is desirable for the thigh protector 10 to have the previously described curvature to approximate the curvature of a typical user's thigh.
The polycarbonate material is formed to the desired curvature to approximate the shape of a typical user's thigh and supports the remainder of the thigh protector 10 in that shape as well. In addition, when the thigh protector 10 is displaced out of its curvature, the shape memory of the polycarbonate material allows the remainder of the thigh protector 10 to return to its original curvature.
In embodiments where the impact resistant component 44 has poor or no shape memory, reinforcement ribs can be used to help maintain the original curvature of the high strength component 44. For example, in one embodiment as shown in
As shown in
The buckle 22 also includes a slot that receives the first adjustment strap 19 and allows a slack between the first adjustment strap 19 and the second adjustment strap 20 to be loosened or tightened, respectively, by pushing the first adjustment strap 19 through the slot or pulling the first adjustment strap 19 through the slot.
Also, in the embodiment of
As shown in
The tool carrier 108 may be removably attached to the band 104 as illustrated in
The tool carrier 108A may be removably attached to the band 104. For example, in one embodiment an outwardly facing flap 192 is coupled to the upper portion 190 of the tool carrier 108A. Preferably, the flap 192 is composed of a flexible material such as leather. The flap 192 may be attached to the upper portion 190 in a manner that allows the flap 192 to be rotated away from the upper portion as shown in
As such, in one embodiment, the tool carrier 108A is releasably attached to the band 104 by inserting the tool carrier 108A into the slot 106 formed by the band 104 and the outer surface 114 of the waist supported structure 100 (see
When so connected, the upper portion 190 of the tool carrier 108A is disposed adjacent to an inner surface of the band 104, and the flap 192 is disposed adjacent to an outer surface of the band 104, such that the band 104 is confined between the upper portion 190 of the tool carrier 108A and the flap 192. In addition, a top edge of the band 104 is disposed adjacent to the rigidly attached juncture 220 of the upper portion 190 of the tool carrier 108A and the flap 192, and a bottom edge of the band 104 is disposed adjacent to the interlocking connection between the upper portion 190 of the tool carrier 108A and the flap 192, such that the band 104 is also confined between the rigidly attached juncture 220 and the releasable interlocking connection of the upper portion 190 of the tool carrier 108A and the flap 192. In this position, the band 104 presses against the outer surface of the upper portion 190 of the tool carrier 108A to secure the tool carrier 108A to the waist supported structure 100. The flap 192 and/or the upper portion 190 of the tool carrier 108A may include a reinforcing material, such as plastic, to increase the structural stability of the tool carrier 108A.
