Patent Description:
The arm (and hand) of the human body has a forearm, comprising the radial part and the ulnar part, a wrist, comprising eight carpalia, a palm comprising five metacarpal joints that enable rotation, flexion, and extension, and fingers comprising a plurality of phalanx bones that enables an object to be held.

These joints can suffer injury, due to repetitive and continuous strain during exercise or an activity carried out by hand, and at the time of injury, healing may not be complete and pain can be continuously suffered.

Accordingly, a wrist guard for protecting the joints and bones by being worn on the wrist of the body has been devised and used.

In general, like other body guards such as ankle guards, wrist guards are worn on the wrist to protect the soft joints of the wrist. Such wrist guards may be worn by athletes who play various sports, workers who do a physical job, or children who enjoy playing, for the safety thereof.

Conventional wrist guards are provided in the form of a band that wraps around the wrist so that the wrist portion (of the arm) is evenly compressed along the circumference thereof. This wrist compression serves to protect the wrist joints and prevent excessive wrist bending.

However, since conventional wrist guards compress the wrist evenly over the entire area thereof, when such wrist guards are worn for an extended period of time, blood flow in the wrist artery may not be smooth, causing hand numbness or swelling of the hand. Because of the same inconvenience, a user may tend to remove or may not wear such a wrist guard at all, so that the use of such a wrist guard is not very effective. As a result, the wrist may not be safely protected during various types of exercise and activities, and thus it may be vulnerable to injury.

<CIT>, which discloses the preamble of claim <NUM>, discloses a band which comprises a band body to be wound around the hand joint and a fastening means for the band body and maintaining the forced-in state of the pressure pad.

Accordingly, the present disclosure has been made in consideration of the above-described problems occurring in the related art, and an object of the present disclosure is to provide a wrist guard capable of compressing only a specific area of the wrist rather than the whole area thereof, so as not to interfere with blood circulation by allowing the remaining part of the wrist to remain uncompressed. The wrist guard can be conveniently used without causing side effects such as hand numbness and swelling of the hands, even when worn for a long period of time, and thus the usability thereof can be improved.

Another object of the present disclosure is to provide a wrist guard capable of compressing only the radial part and the ulnar part of the wrist in the direction of the center of the wrist using a compression pad, thereby preventing the occurrence of side effects such as numbness and swelling of the hand, as well as effectively complementing the attachment to the wrist, so that a wrist protection function of preventing excessive bending of the wrist and alleviating wrist pain can be reliably performed.

A further object of the present disclosure is to provide a wrist guard capable of being used more conveniently by adjusting the position and thickness of a compression pad for compressing the radial part and the ulnar part of the wrist to the optimum state, according to the user's physical condition or environmental condition.

The present disclosure provides a wrist guard for being worn on the wrist to protect the wrist, the wrist guard including: a band body configured to be worn on the wrist by encircling the wrist; and a pair of compression pads disposed on opposite portions of the band body worn on the wrist to respectively compress a part of the wrist, such that a portion of the wrist other than those compressed by the compression pads is not compressed.

The compression pads include a radial compression pad mounted on one portion of the band body to compress the radial part of the wrist and an ulnar compression pad mounted on the other portion of the band body to compress the ulnar part of the wrist.

The radial compression pad may have a length L1 longer than a length L2 of the ulnar compression pad.

At least one of the radial compression pad and the ulnar compression pad may have a concave surface to be in contact with the wrist in a longitudinally intermediate portion thereof.

The compression pads are mounted to be movable in a longitudinal direction of the band body.

A contact surface of the compression pad with the band body may be provided with an insertion protrusion, and the band body may be provided with a pad receiving section in which the insertion protrusion is inserted and movable, the pad receiving section internally having a movement guide part along which the insertion protrusion is forcedly movable in a state of being engaged therewith.

The radial compression pad and the ulnar compression pad may respectively further include a separate auxiliary compression pad detachably attached to a contact surface thereof with the wrist.

The contact surface of the radial compression pad and the ulnar compression pad may be provided with a coupling groove, and the auxiliary compression pad may be provided on one portion thereof with a coupling protrusion to be inserted into and engaged with the coupling groove, so that the auxiliary compression pads are detachably attached to the radial compression pad and the ulnar compression pad, respectively, by ulnar part of the wrist in the direction of the center of the wrist using a compression pad, thereby preventing the occurrence of side effects such as numbness and swelling of the hand, as well as effectively complementing the attachment to the wrist, so that a wrist protection function of preventing excessive bending of the wrist and alleviating wrist pain can be reliably performed.

The compression pads may include a radial compression pad mounted on one portion of the band body to compress the radial part of the wrist and an ulnar compression pad mounted on the other portion of the band body to compress the ulnar part of the wrist.

The compression pads may be mounted to be movable in a longitudinal direction of the band body.

The contact surface of the radial compression pad and the ulnar compression pad may be provided with a coupling groove, and the auxiliary compression pad may be provided on one portion thereof with a coupling protrusion to be inserted into and engaged with the coupling groove, so that the auxiliary compression pads are detachably attached to the radial compression pad and the ulnar compression pad, respectively, by the engagement between the coupling groove and the coupling protrusion.

The coupling groove may be provided with a plurality of coupling grooves in the longitudinal direction of the radial compression pad and the ulnar compression pad to adjust an engagement position of the auxiliary compression pads with the radial compression pad and the ulnar compression pad.

The compression pads may be formed from a leather or silicone material.

The compression pads may be further provided with a health aid to be inserted into the compression pads, the health aid being formed of zirconium or germanium.

The band body may be provided in the form of an elastic ring band, or a band fixedly formed into a ring type by means of a fastener.

As set forth above, the wrist guard is capable of compressing only a specific area of the wrist rather than the whole area thereof, so that the remaining part of the wrist is not compressed, which does not interfere with blood circulation, thereby facilitating convenient use without side effects such as hand numbness and swelling of the hands, even when worn for a long period of time, and thus improving usability.

Further, the wrist guard is capable of compressing only the radial part and the ulnar part of the wrist in the direction of the center of the wrist using a compression pad, thereby preventing the occurrence of side effects such as numbness and swelling of the hand, as well as effectively complementing the attachment to the wrist to reliably perform a wrist protection function to prevent excessive bending of the wrist and alleviate wrist pain.

Still further, the wrist guard is capable of being used more conveniently by adjusting the position and thickness of a compression pad for compressing the radial part and the ulnar part of the wrist to the optimum state, according to a user's physical condition or environmental condition.

Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Throughout this document, reference should be made to the drawings, in which the same reference numerals and symbols will be used to designate the same or like components. In the following description of the present disclosure, detailed descriptions of known functions and components incorporated herein will be omitted in the case that the subject matter of the present disclosure may be rendered unclear thereby.

<FIG> is a perspective view schematically illustrating a wrist guard according to an exemplary embodiment of the present disclosure; <FIG> is a cross-sectional view schematically illustrating a structure of the wrist guard according to the exemplary embodiment of the present disclosure; <FIG> are schematic views illustrating various forms of a band body of the wrist guard according to an exemplary embodiment of the present disclosure; and <FIG> are schematic views illustrating various forms of a compression pad of the wrist guard according to an exemplary embodiment of the present disclosure.

The wrist guard <NUM> according to an exemplary embodiment of the present disclosure is worn on the wrist H of the user to reliably protect the wrist without side effects such as hand numbness. The wrist guard <NUM> includes a band body <NUM> and compression pads <NUM>.

The band body <NUM> is worn on the wrist H by encircling the wrist H. The band body <NUM> may be provided in various forms that can be worn on the wrist H. For example, the band body may be provided in the form of a simple ring-shaped elastic band as illustrated in <FIG>, or may be provided in the form of a band which is fixedly formed into a ring shape by means of a separate fastener such as Velcro T1, T2 as illustrated in <FIG>. In this case, the band may be formed from a fabric.

In the case in which the band body <NUM> is provided in a simple band shape, as illustrated in <FIG>, the band body may be provided on both ends thereof with male and female Velcro parts T2 and T1, respectively, which are fastened together to form the band body into a ring shape. Due to this configuration, the length of the band body is adjustable by a user. Alternatively, as illustrated in <FIG>, the band body <NUM> may be provided with a strap loop <NUM> on one end thereof and male and female Velcro parts T2 and T1 on the other end thereof, such that the male and female Velcro parts T2 and T1 are fastened together while holding the strap loop <NUM>, thereby forming the band body into a ring shape.

Of course, the band body <NUM> may be provided in various forms that are wearable on the wrist, in addition to the above-described configurations.

The compression pads <NUM> are disposed on opposite portions of the band body <NUM> worn on the wrist H to respectively compress a portion of the wrist H. The compression pads <NUM> may be formed of a soft material such as a leather material or a silicone material so as to be in close contact with the wrist H and may be provided in a pad shape having a predetermined thickness so as to be able to compress a portion of the wrist H.

The compression pads <NUM> may include a radial compression pad <NUM> mounted on one portion of the band body <NUM> to compress the radial part H1 of the wrist H, and an ulnar compression pad <NUM> mounted on the other side of the band body <NUM> to compress the ulnar part H2 of the wrist H.

According to this configuration, the wrist guard <NUM> is constructed in such a manner that, in a state in which the band body <NUM> is worn on the wrist H, the compression pads <NUM>, i.e. the radial compression pad <NUM> and the ulnar compression pad <NUM>, compress the radial part H1 and the ulnar part H2 of the wrist H in opposite directions, from the outside toward the center of the wrist H.

Here, the wrist guard <NUM> is configured so as not to compress the wrist other than those compressed by the compression pads <NUM>. That is, the wrist H is not compressed by the band body <NUM>, except for the portion of the wrist H compressed by the compression pads <NUM>. Although a portion of the band body <NUM> may contact the wrist H depending on the thickness of the compression pad <NUM>, the magnitude of the tension of the band body <NUM> surrounding the wrist H, the outer shape of the wrist H, and the like. In this case, the band body <NUM> is simply in contact with the wrist H without compressing the wrist, and even if applied, the contact pressure is very small compared with the compression force applied by the compression pads <NUM>. Accordingly, the contact pressure may be deemed to be ignorable.

As described above, the wrist guard <NUM> is configured such the compression pads <NUM> compress the radial part H1 and the ulnar part H2 of the wrist H to complement the fixing force for the wrist H, thereby preventing excessive bending of the wrist H and relieving the pain of the wrist. Thus, the wrist protection function can be reliably performed. Here, other parts of the wrist are not compressed, except for the radial part H1 and the ulnar part H2 compressed by the compression pads <NUM>, so that the blood circulation is not disturbed, and thus, side effects such as numbness and swelling of hands do not occur.

Meanwhile, a health aid <NUM> may be inserted into the compression pads <NUM> so that various health-aid effects may be provided to the wrist region. Here, the health aid may be formed of zirconium (Zr), germanium (Ge) or the like.

The compression pads <NUM> may be provided in various shapes as illustrated in <FIG>. For example, as illustrated in <FIG>, the length L1 of the radial compression pad <NUM> may be provided to be longer than the length L2 of the ulnar compression pad <NUM>. The bones that make up the arms include the radial part H1 and the ulnar part H2, which protrude outwardly from the wrist H. Here, the radial part H1 is thicker than the ulnar part H2 and has a wider area of protrusion than the ulnar part at the wrist H. Since the radial part H1 has a relatively larger area than the ulnar part in the wrist region, it may be preferred that the radial compression pad <NUM> is provided to be longer than the ulnar compression pad <NUM> to effectively compress the radial part H1 and the ulnar part H2.

The protruding portions of the radial part H1 and the ulnar part H2 in the wrist H are not symmetrically opposed to each other but are slightly displaced. Thus, the radial compression pad <NUM> and the ulnar compression pad <NUM> may be disposed in positions offset from the center line L1 passing through the center C of the ring-shaped band body <NUM> as illustrated in <FIG>. That is, the center C1 of the radial compression pad <NUM> may be located on the center line L1 of the band body <NUM> and the center C2 of the ulnar compression pad <NUM> may be located at a predetermined rotation angle from the center line L1 of the band body <NUM>.

Further, as illustrated in <FIG>, the compression pads <NUM> may be provided to have a concave surface to be brought into contact with the wrist H at a longitudinally intermediate portion thereof. That is, in a case in which the compression pad <NUM> is provided to have a uniform thickness, the contact surface with respect to the wrist H is provided along the line S1 parallel with the curved line of the band body <NUM>, whereas in an exemplary embodiment of the present disclosure, the contact surface with respect to the wrist H may be provided along the line S2 in a concavely curved shape. Since the contact surface with the wrist H is concavely curved so that the compression pads <NUM> can be more closely attached to the wrist H so as to more firmly compress the radial part and the ulnar part of the wrist H.

<FIG> and <FIG> are views schematically illustrating a structure of the compression pad moving along the band body according to an exemplary embodiment of the present disclosure.

As illustrated in <FIG> and <FIG>, the compression pads <NUM> may be mounted to move along the longitudinal direction of the band body <NUM> by a predetermined interval to adjust the mounting positions of the compression pads <NUM>, thereby precisely compressing the radial and ulnar parts, which may be located in positions that are different from user to user.

When the band body is worn on the wrist H, the compression pads <NUM> compress the radial part H1 and the ulnar part H2 of the wrist H in opposite directions. Here, since the shape of the wrist H, positions of the radial part H1 and the ulnar part H2, and the like may differ slightly from person to person, the compression pads <NUM> may not compress the correct points of the wrist depending on the user.

Therefore, by allowing the user to move and adjust the compression pads <NUM> to proper positions, the compression pads <NUM> can be positioned at the correct positions so as to precisely compress the radial part H1 and the ulnar part H2.

For the movement of the compression pads <NUM>, a contact surface of each of the compression pad <NUM> with the band body <NUM> may be provided with an insertion protrusion <NUM>, and the band body <NUM> may be provided with a pad receiving section <NUM> in which the insertion protrusion <NUM> is inserted and movable, wherein the pad receiving section <NUM> internally has a movement guide part <NUM> along which the insertion protrusion <NUM> is forcedly movable in a state of being engaged therewith. Here, as illustrated in <FIG> and <FIG>, the band body <NUM> is formed of a double-layer structure including an inner layer and an outer layer between which the pad receiving section <NUM> is provided. The inner layer may be provided at the center thereof with a cutout portion <NUM>, which extends along the longitudinal direction of the inner layer so that the pad receiving section <NUM> is opened. The insertion protrusion <NUM> is inserted and received in the pad receiving section <NUM> through the cutout portion <NUM> and is movable in the longitudinal direction along the movement guide part <NUM> disposed inside the pad receiving section <NUM>. The movement guide part <NUM> may be provided on opposite lateral sides with concavo-convex portions <NUM> along which the insertion protrusion <NUM> is forcedly movable divisionally in a state of being engaged therewith.

According to this configuration, in a state where the user wears the band body <NUM> on the wrist H, the position of the compression pads <NUM> can be adjusted by pushing or pulling the compression pads <NUM> along the longitudinal direction, thereby enabling the radial part and the ulnar part to be precisely compressed.

<FIG> is a schematic view illustrating an engagement structure of an auxiliary compression pad with the compression pad of the wrist guard according to an exemplary embodiment of the present disclosure.

As illustrated in <FIG>, the compression pad <NUM> may be further provided with a separate auxiliary compression pad <NUM>.

The auxiliary compression pad <NUM> may be configured to be detachably attached to a contact surface of the radial or ulnar compression pad <NUM> or <NUM> with the wrist H. The auxiliary compression pads <NUM> are engaged with the contact surfaces of the radial compression pad <NUM> and the ulnar compression pad <NUM> with respect to the wrist H so as to substantially compress the radial part H1 and the ulnar part H2 of the wrist H. The auxiliary compression pad may be formed of a soft material such as leather or silicone as in the case of the radial compression pad <NUM> and the ulnar compression pad <NUM>.

The thickness of the compression pads <NUM> can be adjusted by attaching or removing the auxiliary compression pads <NUM> to or from the radial compression pad <NUM> and the ulnar compression pad <NUM>. That is, when the auxiliary compression pads <NUM> are respectively attached to the radial compression pad <NUM> and the ulnar compression pad <NUM>, the thickness of the compression pads <NUM> become thicker as a whole, whereas when the auxiliary compression pads <NUM> are respectively removed from the radial compression pad <NUM> and the ulnar compression pad <NUM>, the thickness of the compression pads <NUM> become thinner as a whole.

As a result, the entire thickness of the compression pads <NUM> can be adjusted by using the auxiliary compression pads <NUM>, so that a user can adjust the thickness of the compression pads <NUM> to an appropriate thickness depending on his/her physical condition, an environmental condition, or the like.

Here, a contact surface of the radial compression pad <NUM> and the ulnar compression pad <NUM> with respect to the wrist H may be provided with coupling grooves <NUM>, <NUM>, and the auxiliary compression pads may be provided on one portion thereof with coupling protrusions <NUM> to be inserted into and engaged with the coupling grooves <NUM>, <NUM>, so that the auxiliary compression pads <NUM> are detachably attached to the radial compression pad <NUM> and the ulnar compression pad <NUM>, respectively, by the engagement between the coupling grooves <NUM>, <NUM> and the coupling protrusions <NUM>.

Further, the coupling groove may be provided with a plurality of coupling grooves <NUM>, <NUM> in the longitudinal direction of the radial compression pad <NUM> and the ulnar compression pad <NUM> in order to substantially adjust an engagement position of the auxiliary compression pads <NUM> with the radial compression pad and the ulnar compression pad.
