Wrist guard

Abstract

A wrist guard is disclosed having first and second rigid members to be positioned over the back and front, respectively of a user's hand. The first and second rigid members are joined by flexible straps to permit an adjustment of a spacing between the first and second rigid member. Each of the first and second rigid members are symmetrical along the longitudinal axes of the first and second rigid members such that the wrist guard can be worn on either the left or right hand of a user without interfering with the flexing of the fingers or thumb of the user.

Description

I. BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention pertains to protective wear for use in activities such as in-line skating or the like. More particularly, this invention pertains to a wrist guard for protecting a wrist and hand of a user during such activities.

2. Description of the Prior Art

In-line skating has become very popular. In order to protect a skater from injuries resulting from falls, skaters typically wear protective gear such as helmets, knee guards and wrist guards.

A wrist guard limits backward flexing of the hand relative to the forearm to reduce the risk of hyperextension of the wrist in the event of a fall. Further, wrist guards typically include an abrasive pad or the like in the palm region of the hand to protect the palm from abrasion.

Numerous designs of wrist guards are available. However, many such designs are cumbersome to use and uncomfortable to wear. Further, prior art wrist guards are dedicated to either the left or right hand of the user. Namely, a wrist guard designed for the right hand of the user can not be comfortably used on the left hand of the user. The absence of interchangeability between the left and the right hands is particularly frustrating for children who may frequently attempt to wear the left wrist guard on the right hand and visa versa. Where wrist guards are uncomfortable or awkward to put on or use, a skater may, out of frustration, elect not to wear a wrist guard.

It is an object of the present invention to provide a wrist guard which is comfortable to wear and easy to use. It is a further object of the present invention to provide such a wrist guard which is interchangeable for use on either the right and left hands of the user.

II. SUMMARY OF THE INVENTION

According to a preferred embodiment of the present invention, a wrist guard includes first and second rigid members each having longitudinal axes extending from a front end to rear end. The first rigid member has a length selected for its front end to be disposed at a knuckle line at the back of a user's hand and extending centrally along the back of the hand beyond the wrist of the user for the rear end to be disposed over a back side of a forearm of the user. The side edges of the first rigid member are symmetrical about the longitudinal axis of the first rigid member. The second rigid member has a length selected for the front end to be disposed at a first joint line of a palm of the user's hand and with the front end extending centrally along the palm with the total length of the second rigid member being less than the length of the first rigid member. The side edges of the second rigid member are symmetrical about the longitudinal axis of the second rigid member. Fastener straps join the front ends and the wrist portions of the first and second rigid members in parallel spaced-apart alignment. The straps are adjustable to permit the user to selectably adjust a spacing between the first and second rigid members. Opposing edges of the strap members define spaces on opposite sides of the rigid members with the spaces sized to pass the thumb of the user.

IV. DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the various drawing figures in which identical elements are numbered identically throughout, a description of the preferred embodiment will now be provided.

The present invention is directed to a wrist guard 10 which includes a back (or first) rigid member 12 and a front (or second) rigid member 14. The first and second rigid members 12, 14 are disposed in generally parallel spaced-apart alignment as best shown in FIG. 3. Each of the rigid members 12, 14 includes a rigid plastic shell 12a, 14a which is abrasion resistant. The members 12, 14 further include a padded inner liner 12b, 14b for comfort against a user's skin. The liner 14b includes a plurality of molded domes 15 to space the liner 14b from the palm to permit air circulation.

The first rigid member 12 has a first longitudinal axis X--X (FIG. 1) extending from a front end 12c to a rear end 12d. The front end 12c is disposed along the knuckle line (i.e., the knuckles where the user's fingers are jointed to the user's hand). The first end 12c has a transverse length perpendicular to axis X--X less than the width of the user's hand.

The first rigid member extends centrally along the back of the user's hand and beyond a pivoting wrist area Y--Y (FIG. 1) to the rear end 12d which is disposed over a back side of a forearm of the user. Side edges 12e, 12f, extend from the front end 12c to the rear end 12e and are symmetrical about the first longitudinal axis X--X. The edges 12e, 12f are spaced from the longitudinal axis X--X such that the thumb is freely flexible and flexing of the thumb is not interfered with by the edges 12e, 12f regardless of whether the first rigid member is positioned over the back of a left or right hand of the user.

Both the rigid plastic portion 12a and foam portion 12b are provided with a plurality of cutouts 16 disposed along axis X--X to permit air to freely circulate to the back of the user's hand for comfort and cooling. At the front end 12c, the first rigid member 12 is forked to present two spaced-apart ribs 13a, 13b, which are disconnected at the front end 12c. In the event of a skater's fall, the ribs 13 may flex apart slightly to absorb part of the force of the fall.

The second rigid member 14 extends from a front end 14c to a rear end 14d along a second longitudinal axis X'--X'. The front end 14c is disposed along a palm of the user's hand with the front end 14c disposed adjacent a first joint line along the palm (i.e., the joint line where the user's fingers are jointed to the user's hand). The length of the second rigid member 14 is less than the length of the first rigid member 12 to permit the user to have greater downward flexing of the wrist than upward flexing of the wrist.

The second rigid member 14 includes side edges 14e, 14f which are spaced from the second axis X'--X' by a distance sufficient to permit downward flexing of the user's thumb without interference regardless of whether the wrist guard 10 is worn on the right or left hand of the user. The side edges 14e, 14f are symmetrical about axis X'--X'.

The second rigid member 14 includes a convex cup 18 disposed in the heel region of the user's hand to accommodate the heel region of the user's hand. Preferably, abrasive resistant pads 19 are provided in the cup portion 18 to add additional abrasion protection.

First and second straps 20, 22 are provided. The straps permit the user to selectively adjust the spacing between the first and second rigid members 14. The first strap 20 is provided at the front ends 12c, 14c.

The strap 20 has a first end 20a secured to the front end 14c at edge 14f. The strap 20 passes through a slot 20b in the upper rigid portion 12 at rib 13a and passes across the upper rigid portion 12 to a second slot 20c at rib 13b. The strap 20 then passes through a slot 20d in the second rigid portion 14 (at front end 14c of edge 14e) with a free end 20e of the strap 20 folded over the portion of the strap 20 passing between slots 20b, 20c. Opposing portions of the strap between slots 20b, 20c are provided with mating hook and loop fasteners 20f to permit the user to fasten strap 20 in any one of a plurality of fixed positions to adjust the spacing between the front ends 12c, 14c.

Strap 22 is provided surrounding a wrist portion of the user adjacent end 14b. A first end 22a of the strap 22 is secured to the upper rigid portion 12 at edge 12e. The strap passes through a slot 22b in the lower rigid portion 14 adjacent edge 14f. The strap 22 then passes through a second slot 22c in the lower rigid portion 14 adjacent edge 14e and subsequently passes through a slot 22d in the upper rigid portion adjacent edge 12f.

A free end 22e of the strap 22 can be folded over the portion of the strap extending between slots 22b, 22c. Opposing portions of the strap 22 are provided with mating hook and loop fasteners 24 to permit a user to fasten the strap 22 in any one of a plurality of releasable fixed positions in order to adjust a spacing between the rigid members 12, 14 at the wrist portion of the wrist guard 10. Opposing edges of the straps 20, 22 define spaces 30 on both sides of the wrist guard 10 with the spaces 30 sized to freely pass a thumb of the user.

With the construction thus described, the wrist guard can be worn on either the right or the left hand with the thumb passing through the spaces 30 and having free flexing motion regardless of whether the wrist guard 10 is worn on the right or the left hand of the user. The wrist guard 10 permits the user's fingers to have full flexing capabilities in order to increase the comfort of the user. The heel of the hand is contained within the cup 18 for both comfort and positioning in the event of impact. Since the plastic 12 is only slightly flexible, the rigid plastic member having its end 12d disposed over the back of the forearm greatly restricts upward flexing of the hand relative to the forearm to prevent hyperextension of the wrist in the event of a fall. The symmetrical nature of the rigid members 12, 14 with respect to the longitudinal axes X--X and X'--X' further facilitates the use of the wrist guard 10 on either the right of the left hand to avoid frustration when attempting to wear the wrist guard 10 or to avoid improper use.

When the foregoing detailed description of the present invention has been shown of the objects of the invention have been attained in the preferred manner. Modifications and equivalents of the disclosed concepts are intended to be included within the scope of the claims which are appended hereto.
