Description

FIELD OF THE INVENTION

This invention relates generally to the field of articles worn by persons to reduce the likelihood, severity, or exacerbation of injury to the body, and more specifically to the field of braces worn on the wrist.

BACKGROUND OF THE INVENTION

Flexible wrist braces are used by athletes and other persons engaged in vigorous physical activity to protect the elbow from injury and to avoid exacerbation of existing injury.

Devices to protect the wrist against abnormal motions have been used for many years, in a variety of specific embodiments which vary in their abilities to protect against the different types of abnormal motions. However, the protections afforded by these devices against abnormal motion are often accompanied by a reduction in range or ease of normal motion, and may be accompanied by other undesirable aspects such as poor performance, added weight, difficulty of application, fit, cost, and/or appearance.

For these reasons, there has long been motivation to find an improved wrist brace which can protect and support the wrist without affecting the range or ease of normal motion, while avoiding the undesirable aspects of prior art devices.

SUMMARY OF THE INVENTION

In a first embodiment, a wrist brace according to the present invention includes a base and a pair of outside fastening straps that pass through apertures in the base to hold the brace on the wrist of a person. A third fastening strap has an end permanently fastened to the interior surface of the base, extending between the base and a semi-rigid or flexible stay adjacent to the wrist and then passing through an aperture in the base. Tension applied to the third strap can pull the inside support stay closer to the wrist. An outside stay can also be provided for additional support.

In an alternate embodiment, a wrist brace according to the present invention includes a base and a pair of outside fastening straps, with a third fastening strap permanently fastened to the exterior surface of the base, extending between the base and a semi-rigid or flexible stay adjacent to the wrist. The third strap can pull the inside support stay closer to the wrist.

Further objects, features, and advantages of the invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings, FIGS. 1A-1C show a wrist brace 120 according to the present invention. The wrist brace 120 includes a base member 122 made by cutting planar sheets of one or more elastomeric materials into the desired shape. The exterior surface of the base member 122 is preferably covered with fabric bearing fiber loops 124 that adheres to hook-type material when the fiber loops and hook-type material are pressed together. The base may include base edge binding 125.

The wrist brace 120 is formed to fit the human wrist and hand, and the base 122 has a thumb hole 126 to receive the thumb when worn. The wrist brace 120 may have a splint pocket 127 containing a rigid or flexible splint 128 shaped to fit the wrist and the palm of the hand when worn.

The wrist brace 120 also includes a first fastening strap 130, a second fastening strap 132, and a middle strap 134, which are preferably formed of a material that is somewhat elastic along the length of the straps. The base 122 includes a first aperture 131, a second aperture 133, and a middle aperture 136, all formed as reinforced apertures 144. The wrist brace 120 also includes a sleeve 136 for convenience of application.

Each of the first fastening strap 130, second fastening strap 132, and middle strap 134 terminates in a hook-type fastening tab 140 permanently fastened to the strap, for example by stitches 142. The fastening tabs 140 allows the straps to be tightened, and then detachably attached to the exterior surface of the base 122 to securely fasten the wrist brace on the wearer. Normally the first fastening strap 130 and the second fastening strap 132 are tightened first in order to secure the brace on the wrist and hand, then the middle strap 134 can be adjusted to provide the desired support to the palm.

FIGS. 2A and 2B are front and side views of an outside support stay for use in the wrist brace of FIGS. 1A-1C;

FIGS. 3A and 3B are perspective and cross-section views of an inside support stay for use in the wrist brace of FIGS. 1A-1C;

FIG. 4A is a perspective view of an aperture reinforcement base for use in the wrist brace of FIGS. 1A-1C;

FIG. 4B is a perspective view of an aperture reinforcement backing for use in the wrist brace of FIGS. 1A-1C.

FIGS. 5A-5C show an alternate wrist brace 220 according to the present invention. The wrist brace 220 includes a base member 222 made by cutting planar sheets of one or more elastomeric materials into the desired shape. The exterior surface of the base member 222 is preferably covered with fabric bearing fiber loops 224 that adheres to hook-type material when the fiber loops and hook-type material are pressed together. The base may include base edge binding 225.

The wrist brace 220 may include one or more pockets to hold small items such as keys, access fobs, ID or credit cards, smart devices (for example fitness trackers) or visible flair 246 such as brightly colored items, reflectors, blinking lights, glow sticks, lighting, or reflective patches can be provided to enhance visibility of the wearer.

The wrist brace 220 is formed to fit the human wrist and hand, and the base 222 has a thumb hole 226 to receive the thumb when worn. The wrist brace 220 may have a splint pocket 227 containing a rigid or flexible splint 228 shaped to fit the wrist and the palm of the hand when worn.

The wrist brace 220 also includes a first fastening strap 230, a second fastening strap 232, and a middle strap 234, which are preferably formed of a material that is somewhat elastic along the length of the straps. The base 222 includes a first aperture 131 and a second aperture 133, both formed as reinforced apertures 144. The wrist brace 220 also includes a sleeve 236 for convenience of application.

Each of the first fastening strap 230, second fastening strap 232, and middle strap 234 terminates in a hook-type fastening tab 240 permanently fastened to the strap, for example by stitches 242. The fastening tab 240 allows the straps to be tightened, and then detachably attached to the exterior surface of the base 122 to securely fasten the wrist brace on the wearer. The wrist brace 120 may include one or more

FIGS. 5C and 5D show the wrist brace 220 applied to the hand of a person, with all the straps loose so the brace 220 is loosely retained on the hand by the sleeve 236 and base 222. This is the first step in applying the brace to a person.

FIGS. 5E, 5F, and 5G show the wrist brace 220 applied to the wrist and hand of a person, with all the straps fastened down. Normally the first fastening strap 230 and the second fastening strap 232 are tightened first in order to secure the brace on the wrist and hand, then the middle strap 234 can be adjusted to provide the desired support to the palm. Advantageously, all the strap ends align at the same general location when tightened and fastened down. This makes it easier to iteratively adjust the tension in the straps, to achieve maximum comfort and support for that particular wearer of the wrist brace.
