Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to an auxiliary pad for a bowling wrist guard, and more particularly to an auxiliary pad detachably attached to a bowling wrist guard and having improved air permeability.  
         [0003]     2. Description of the Prior Art  
         [0004]     In general, a bowler wears a bowling wrist guard so as to prevent an injury of a wrist or finger which may occur due to a weight of a bowling ball and to correctly throw the bowling ball according to the bowler&#39;s throwing characteristics during bowling.  
         [0005]     The bowling wrist guard is mainly made of a metal. Accordingly, when a bowler directly wears the metal wrist guard on the wrist, the feeling is poor. In addition, since the bowling wrist guard is not in perfectly close contact with a bowler&#39;s wrist or back of the hand, the wrist guard moves when the bowler throws the bowling ball, so that it is impossible to correctly throw the bowling ball.  
         [0006]     An auxiliary pad for a bowling wrist guard for solving the problem is disclosed in Korean Patent Registration No. 320, 301.  
         [0007]      FIG. 1  is a view showing a bowling wrist guard capable of adjusting an angle according to the prior art, and  FIG. 2  shows that the auxiliary pad as disclosed in the Korean Patent is attached to an inside of the bowling wrist guard.  
         [0008]     Referring to  FIG. 1 , the bowling wrist guard capable of adjusting an angle  100  comprises a guard member  120  closely contacting and protecting the back of the hand (hereinafter, referred to as ‘hand-back’), a wrist guard member  140  closely contacting the exterior of a wrist, and a connection member  130  connecting the hand-back guard member  120  and the wrist guard member  140  and adjusting a left-and-right or up-and-down connection angle of the hand-back guard member  120  and the wrist guard member  140 .  
         [0009]     The hand-back guard member  120  and the wrist guard member  140  comprise a hand-back cushion element  125  and a wrist cushion element  145  therein, respectively. Auxiliary pads  150 ,  170  are respectively attached to the hand-back cushion element  125  and the wrist cushion element  145 .  
         [0010]      FIG. 2  shows that the hand-back auxiliary pad  150  and the wrist auxiliary pad  170  are respectively attached to the hand-back cushion element  125  and the wrist cushion element  145 . Although it is not shown in  FIGS. 1 and 2 , hook-and-loop type fasteners are applied to inner surfaces of the hand-back cushion element  125  and the wrist cushion element  145  and to corresponding sides of the hand-back auxiliary pad  150  and the wrist auxiliary pad  170 . Accordingly, a bowler attaches the auxiliary pads  150 ,  170  having a proper thickness to the hand-back cushion element  125  and the wrist cushion element  145  to improve the feeling with the hand-back and the wrist. The bowler may further attach an additional auxiliary pad  160  to the hand-back cushion element  125  as necessary depending on the connection angle of the hand-back guard member  120 , thereby improving the feeling.  
         [0011]     However, the auxiliary pad is shaped into a plate form having a uniform thickness. Accordingly, as the hand profiles of bowler&#39;s differ from each other, a bowler&#39;s hand-back and wrist part may not perfectly and closely contact the auxiliary pad, so that the bowler cannot consistently throw the bowling ball and wrist guard feeling is poor.  
         [0012]     In addition, the auxiliary pad has poor air permeability. Accordingly, when the bowler wears the bowling wrist guard having the auxiliary pads attached thereto for a long time and sweats, the feeling of the auxiliary pad is deteriorated on account of the sweat. In severe cases, an odor can sometimes be produced.  
       SUMMARY OF THE INVENTION  
       [0013]     Accordingly, the present invention has been made to solve the above problems. An object of the invention is to provide an auxiliary pad for a bowling wrist guard closely contacting a bowler&#39;s hand-back or wrist to allow the bowler to consistently throw a bowling ball and having improved air permeability for improved feeling and comfort.  
         [0014]     In order to achieve the above object, there is provided an auxiliary pad for a bowling wrist guard comprising an auxiliary pad detachably attached to a cushion element that is attached to an inside of the bowling wrist guard, wherein the auxiliary pad comprises a first layer contacting a bowler&#39;s hand-back or wrist, a second layer having elasticity, and a third layer having air permeability.  
         [0015]     According to an embodiment of the invention, the bowling wrist guard may comprise a hand-back guard member and a wrist guard member having a hand-back cushion element and a wrist cushion element attached to insides thereof, respectively. The auxiliary pad may comprise a hand-back auxiliary pad and a wrist auxiliary pad detachably attached to the hand-back and wrist cushion elements, respectively.  
         [0016]     Further, according to an embodiment of the invention, hook-and-loop fastener tapes may be attached to inner surfaces of the hand-back and to wrist cushion elements and upper surfaces of the hand-back and wrist auxiliary pads, respectively, so that the hand-back and wrist auxiliary pads can be detachably attached to the hand-back and wrist cushion elements.  
         [0017]     According to an embodiment of the invention, the first layer may be made of a material having excellent perspiration absorption ability. The second layer may be made of an active carbon polyurethane sponge having excellent ventilation ability and may include a natural perfume ingredient so that a fragrance is generated when a bowler wears the guard. The third layer may be made of an air mesh having excellent air permeability.  
         [0018]     According to an embodiment of the invention, the hand-back auxiliary pad may have a profile bent in the width and longitudinal directions thereof and be made such that a periphery thereof is thicker than a center part thereof, corresponding to a shape of a hand in throwing a bowling ball. Accordingly, the bowler&#39;s hand-back can be in close contact with the hand-back guard member.  
         [0019]     According to an embodiment of the invention, the hand-back auxiliary pad may be replaced by detaching and attaching it to the hand-back cushion element.  
         [0020]     In addition, according to an embodiment of the invention, the wrist auxiliary pad may have a profile bent in a width direction thereof and be made such that a side part thereof is thicker than a center part thereof. Accordingly, it is possible to keep the bowler&#39;s wrist fixed to the wrist guard member while throwing the bowling ball. The wrist auxiliary pad may be replaced by detaching and attaching it to the wrist cushion element.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0031]     Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when such description would make the subject matter of the present invention unclear.  
         [0032]     Shapes and functions of hand-back and wrist auxiliary pads according to the invention will be first specifically described. The wearing by a bowler of a bowling wrist guard having the hand-back and wrist auxiliary pads attached thereto will then be described.  
         [0033]      FIG. 3  is a plan view of a hand-back auxiliary pad  10  according to a preferred embodiment of the invention. The bowler&#39;s hand  11  which is present under a hand-back auxiliary pad  10  is shown with a phantom line.  
         [0034]     Referring to  FIG. 3 , the hand-back auxiliary pad  10  is detachably attached to a hand-back cushion element  52  (refer to  FIG. 9 ) that is attached to an inside of a bowling wrist guard  50  (refer to  FIG. 9 ), thereby covering a bowler&#39;s hand-back.  
         [0035]     The hand-back auxiliary pad  10  has a shape to correspond to the bowler&#39;s hand-back so that it can cover a bowler&#39;s hand  11 . Specifically, the hand-back auxiliary pad  10  is made to have a size and a shape capable of covering the bowler&#39;s hand-back. In particular, at a location corresponding to the bowler&#39;s index and middle fingers, it is formed with an extension part  12  that is protrudingly extended by a predetermined length. The extension part  12  is protruded to cover the bowler&#39;s index and middle fingers up to the first knuckles thereof. Accordingly, when a bowler wears the bowling wrist guard  50 , since the extension part  12  covers the bowler&#39;s index and middle fingers up to the first knuckles thereof, it supports the index and middle fingers in throwing a bowling ball so that the bowler can throw the bowling ball more easily.  
         [0036]     The hand-back auxiliary pad  10  is detachably attached to the hand-back cushion element  52 . Specifically, a hook-and-loop fastener, such as a Velcro tape  20  is attached to a center part of an upper surface of the hand-back auxiliary pad  10  and a mating tape  53  (refer to  FIG. 9 ) is attached to an inner surface of the hand-back cushion element  52  of the bowling wrist guard  50 . The bowler fixes or separates the tape  20  of the hand-back auxiliary pad  10  to or from the tape  53  of the hand-back cushion element  52 , thereby detaching or attaching the hand-back auxiliary pad  10  to the hand-back cushion element  52  as required. The tape  20  is not attached to completely cover the upper surface of the hand-back auxiliary pad  10 , but is provided on the center part only, thereby increasing an air permeability of the hand-back auxiliary pad  10  which will be described later.  
         [0037]      FIGS. 4 and 5  are front and side views of the hand-back auxiliary pad  10  according to an embodiment of the invention.  
         [0038]     Referring to  FIGS. 4 and 5 , the hand-back auxiliary pad  10  has a profile that is bent in the width and longitudinal directions thereof along the bowler&#39;s hand-back. Since the bowler&#39;s hand  11  takes a profile that is bent in width and longitudinal directions in throwing the bowling ball, as shown in  FIGS. 4 and 5 , the hand-back auxiliary pad  10  closely contacts the bowler&#39;s hand-back along the corresponding bent profile.  
         [0039]     Further, as shown in  FIGS. 4 and 5 , the hand-back auxiliary pad  10  is made such that a periphery thereof is thicker than a center part thereof. Such shape corresponds to the shape of the bowler&#39;s hand-back made when the bowler grasps the bowling ball so as to throw the ball. In other words, when the bowler throws the bowling ball, the hand protrudes at a center thereof and takes a bent shape at the periphery. Accordingly, the hand-back auxiliary pad  10  interposed between the bowler&#39;s hand and the hand-back cushion element  52  for the bowling wrist guard  50  is profiled such that it has a thin center part and becomes thicker as the periphery is approached, thereby closely contacting the bowler&#39;s hand-back.  
         [0040]     In addition, since the extension part  12  is a part for supporting fingers used for throwing, it is made to have a proper thickness suitable for the bowler&#39;s throwing habit. Preferably, the extension part  12  of the hand-back auxiliary pad  10  is made to have a thickness corresponding to the space that would otherwise exist between the position of the fingers and the hand-back cushion element  52  when throwing the bowling ball. With the extension part  12 , the bowler&#39;s finger is located and fixed at the extension part  12 , so that the bowler can throw the bowling ball with a more stable posture.  
         [0041]     Further, when the bowler wears the bowling wrist guard  50  having the hand-back auxiliary pad  10  attached thereto according to the invention, the hand-back auxiliary pad  10  covers the bowler&#39;s fingers and hand-back. Accordingly, the bowler can maintain the posture at the time when she or he throws the bowling ball, even though she or he does not apply a separate force. Thereby, muscular fatigue can be relieved and the bowler can consistently throw the bowling ball.  
         [0042]     The shape of the hand-back auxiliary pad  10  can be changed in accordance with the size of the bowler&#39;s hand or the form of the hand depending on the bowler&#39;s throwing form. Accordingly, the bowler can select and attach the most suitable hand-back auxiliary pad  10  to the bowling wrist guard  50  with regard to his or her throwing habits. If the bowler changes the throwing motion, the bowler can select the most suitable hand-back auxiliary pad for the changed motion and easily change the hand-back auxiliary pad  10 .  
         [0043]      FIG. 6  is a sectional view taken along a line VI-VI′ in  FIG. 3 , which shows a section of the hand-back auxiliary pad  10  according to an embodiment of the invention.  
         [0044]     Referring to  FIG. 6 , the hand-back auxiliary pad  10  comprises a first layer  14  contacting the bowler&#39;s hand-back, a second layer  16  having an elasticity, and a third layer  18  having an air permeability.  
         [0045]     The first layer  14  directly contacting the bowler&#39;s hand-back is made of a material having an excellent perspiration absorption ability, for example Coolmax® fabric available from Dupont. Since the first layer  14  is made of a material having an excellent perspiration absorbtion ability, even though the bowler&#39;s hand is in a sweat, the first layer rapidly absorbs and discharges the sweat to the second layer  16 . Accordingly, even when the bowler wears the bowling wrist guard  50  (refer to  FIG. 9 ) for a long time and thus sweats, the first layer  14  always maintains an optimal state.  
         [0046]     The second layer  16  having an elasticity is located between the first layer  14  and the third layer  18 . Preferably, the second layer  16  is made of a material having an excellent ventilation ability, for example active carbon polyurethane filter sponge. The second layer  16  ventilates the sweat delivered by the first layer  14 , thereby allowing the hand-back auxiliary pad  10  to maintain its optimal state.  
         [0047]     In addition, since the sponge member has a proper elasticity, it covers and supports the bowler&#39;s hand-back or finger when the bowler wears the bowling wrist guard  50 , thereby increasing the feel and relieving the fatigue of the hand-back or finger.  
         [0048]     The sponge member constituting the second layer  16  generally serves to determine the thickness of the hand-back auxiliary pad  10 . For example, the sponge member is made of a single layer at the center part of the hand-back auxiliary pad  10  and multiple layers at the periphery thereof, so that the periphery is thicker than the center part. The hand-back auxiliary pad  10  having such thickness closely contacts the bowler&#39;s hand-back, as described above. Accordingly, in the hand-back auxiliary pad  10  of the invention, the thickness of the second layer  16  is changed to adjust the thickness of the hand-back auxiliary pad  10 .  
         [0049]     According to another embodiment of the invention, a natural perfume may be added to the sponge member constituting the second layer  16 . For example, the sponge layer constituting the second layer  16  is treated to include a phytoncide ingredient so that the bowler can smell the natural perfume when the bowler wears the bowling wrist guard  50 .  
         [0050]     The third layer  18  located on the top of the hand-back auxiliary pad  10  is made of a material having an excellent air permeability, for example an air mesh. The air mesh is a structure similar to a so-called net structure, which is a material having improved air permeability by maximizing an air inflow from the exterior or an air outflow to the exterior. Accordingly, the third layer  18  allows the external air to easily pass through and thus helps the sweat in the second layer  16  to be evaporated more easily.  
         [0051]     A hoop-and-loop tape  20  is attached to an upper part of the third layer  18 , as described above. The tape  20  does not completely cover the third layer  18  so as to maintain the air permeability of the third layer  18 , but is located at a certain region only, for example a center part of an upper surface of the hand-back auxiliary pad  10 . In addition, the tape  20  can be formed with a plurality of ventilation holes  22 .  
         [0052]      FIG. 7  is a plan view showing a wrist auxiliary pad  30  according to a preferred embodiment of the invention. The wrist auxiliary pad  30  has the same internal structure as the hand-back auxiliary pad  10  except for the shape thereof. Hereinafter, it will be described on the basis of the shape of the wrist auxiliary pad  30 .  
         [0053]     Referring to  FIG. 7 , the wrist auxiliary pad  30  according to the invention is detachably attached to a wrist cushion element  54  (refer to  FIG. 9 ) of the bowling wrist guard  50  to cover the bowler&#39;s wrist. As shown in  FIG. 7 , a hook-and-loop tape  32  is attached to an upper surface of the wrist auxiliary pad  30 , so that the wrist auxiliary pad  30  can be detachably attached to the wrist cushion element  54 .  
         [0054]      FIG. 8  is a front view showing the wrist auxiliary pad  30  seen from the ‘A’ direction in  FIG. 7 .  
         [0055]     Referring to  FIG. 8 , the wrist auxiliary pad  30  has a profile bent in a width direction thereof across the bowler&#39;s wrist. In addition, both sides are thicker than a center part thereof. With such a shape of the wrist auxiliary pad  30 , the bowler&#39;s wrist is well and closely contacted by the bowling wrist guard  50 , so that the bowler can stably move the wrist when throwing the ball. Although the figure shows that both pad sides are separate from the wrist, the wrist auxiliary pad  30  is closely contacted to the wrist by a fastening band  59  (refer to  FIG. 9 ) of the bowling wrist guard  50  (refer to  FIG. 9 ), which will be described later.  
         [0056]     A procedure for wearing the bowling wrist guard  50  having the hand-back and wrist auxiliary pads  10 ,  30  attached thereto according to a preferred embodiment of the invention will be described with reference to  FIG. 9 .  
         [0057]      FIG. 9  shows that the hand-back and wrist auxiliary pads  10 ,  30  according to a preferred embodiment of the invention are attached to the bowling wrist guard  50  and are provided with specific reference to the bowler&#39;s hand.  
         [0058]     Referring to  FIG. 9 , the bowler first selects the appropriate hand-back auxiliary pad  10  and the wrist auxiliary pad  30 . In other words, among hand-back auxiliary pads having diverse thicknesses, the bowler selects the hand-back auxiliary pad  10  according to the bowler&#39;s throwing habits, and which covers the finger and wrist well and closely contacts them. In addition, the bowler selects the wrist auxiliary pad  30  having a thickness suitable for the bowler&#39;s wrist.  
         [0059]     After selecting the hand-back and wrist auxiliary pads  10 ,  30 , the bowler attaches the hand-back and wrist auxiliary pads  10 ,  30  to the bowling wrist guard  50 . In this case, the bowler attaches the tapes  20 ,  32  provided on the upper surfaces of the hand-back and wrist auxiliary pads  10 ,  30  and the complimentary tapes  53 ,  55  provided to the hand-back and wrist cushion element  52 ,  54  to each other, thereby fixing the hand-back and wrist auxiliary pads  10 ,  30  to the bowling wrist guard  50 .  
         [0060]     After fixing the hand-back and wrist auxiliary pads  10 ,  30  to the bowling wrist guard  50 , the bowler fastens the bowling wrist guard  50  to the hand  11  using the fastening bands  57 ,  59  provided on both sides of the bowling wrist guard  50 .  
         [0061]     After fastening the bowling wrist guard  50  to the hand-back and the wrist, the bowler adjusts the bowling wrist guard  50  according to his or her throwing habits and then bowls.  
         [0062]     As described above, according to the invention, when the bowler uses the bowling wrist guard having the hand-back and wrist auxiliary pads of the invention, the bowler can consistently throw a bowling ball since the positions of the finger and the hand-back are fixed due to the hand-back auxiliary pad.  
         [0063]     In addition, according to the invention, since the position of the fingers in throwing is supported by the extension part of the hand-back auxiliary pad, it is not necessary to continuously apply force to the fingers, so that the fatigue of finger muscles is relieved and playing performance is thus improved.  
         [0064]     Additionally, according to the invention, the auxiliary pads are made of materials having an excellent perspiration absorption ability or air permeability, so that sweat is easily exhausted and evaporated. Accordingly, even when the bowler wears the bowling wrist guard for a long time, the feeling falloff and sweat odor are prevented.  
         [0065]     Further, according to the invention, the bowler need only replace the hand-back and wrist auxiliary pads for a new throwing form when the bowler changes his or her throwing motion; the entire bowling wrist guard need not be replaced. Accordingly, the bowling wrist guard of the invention is more economical than the prior art.  
         [0066]     While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made thereto without departing from the spirit and scope of the invention as defined by the appended claims.
