Hereinafter, the operation of the wrist support for bowling according to the present invention will be described in detail with reference to the accompanying drawings.

11 and 12 are diagrams for explaining the operation of the first wire reel of the wrist guards for bowling according to the present invention.

11 and 12, when a user wishes to wear the bowling protector 1 according to the present invention, he or she pushes the hand between the wing plate 10 and the cuff support 60, And the protective cover 70, as shown in Fig.

The first wire reel 80 and the second wire reel 90 formed on the wrist plate 10 and the hand platen 20 respectively in order to bring the cuff bracket 60 and the protective cover 70 into close contact with each other, The rotation knob N is rotated in one direction.

11 (a), the second latching projection N2 of the rotary knob N is rotated together to move to a position not in contact with the elastic toothed member T, and as a result, the elastic toothed member T is kept in a state where the second teeth T1 of the elastic toothed member T are engaged with the first teeth H2 of the housing H for reel while the circular shape is maintained.

11 (a) to 11 (d), when the user rotates the rotary knob N in the same direction, one end of the second latching projection N2 is engaged with the first end of the spool S The first latching protrusion S4 is rotated by the latching protrusion S4 to rotate the spool S.

When the spool S is rotated, the second toothed portion T 1 rides over the first toothed portion H 2 of the reel housing H while the resilient toothed member T is being moved, whereby the spool S is rotated The first wire (W1) and the second wire (W2) are wound around the spool (S). The second teeth T1 of the elastic toothed member T and the first toothed portions H2 of the reel housing H are kept in meshing engagement with each other so that the spool S is fixed , The first wire (W1) and the second wire (W2) maintain their current length. The first wire W1 and the second wire W2 are maintained in a constant shape by the first guide member 11 of the wrist plate 10 and the second guide member 21 of the hand plate 20, Only the length is adjusted.

Thus, when the first wire W1 and the second wire W2 are wound on the spool S, the cuff support 60 and the protection cover 70 are brought into close contact with the user's cuff and palm.

In this state, the user adjusts and uses the tilting adjusting member 40 and the swing adjusting member 50.

On the contrary, when the user desires to take off the wrist strap 1 for bowling according to the present invention, when the user tries to take off the first wrist strap 10 formed on the wrist strap 10 and the hand strap 20 as shown in Fig. 12 (a) The rotation knob N of the reel 80 and the second wire reel 90 is rotated about 1/3 in the other direction.

12 (b), the second latching projection N2 of the rotary knob N is rotated to press-fit the second tooth T1 of the elastic toothed member T to deform the shape, The engagement of the second teeth T1 of the elastic toothed member T and the first toothed H2 of the reel housing H is released.

12 (c), the user advances the locking protrusion R1 of the locking member R so that the first locking protrusion S4 of the spool S and the second locking protrusion S4 of the rotation knob N And inserted between the second latching protrusions N2.

Subsequently, when the user pulls the first wire W1 and the second wire W2, since the locking protrusion R1 and the first latching protrusion S4 and the second latching protrusion N2 are in close contact with each other, the spool S is rotated and the rotary knob N is rotated together with the rotation of the spool S so that the first wire W1 and the second wire W2 are rotated together with the spool S ).

Then, when the first wire W1 and the second wire W2 are loosened and the length is extended, the cuff support 60 and the protection cover 70 are separated from the user's cuff and the user pulls out the arm and the hand.
