Description

[Detailed Description of the Invention] The present application relates to a shoulder clap with improved operability. The conventional shoulder tat has a grip handle at one end on a straight line in the longitudinal direction,
It consists of a rod or plate in the middle and a ball at the other end. As a result, there are problems such as not being able to reach the back of the shoulder when striking, making the arm tired when striking strongly, and causing the middle part to break if bent too much.

The present application was devised to solve these problems, and by using a curved leaf spring formed by a combination of a plurality of leaf springs, its curvature and spring stress can easily reach the back of the shoulder, and the hitting force This provides a shoulder hit that reduces arm fatigue and eliminates the bend in the middle.

Hereinafter, the configuration of the present application will be explained based on drawings of embodiments.A long upper leaf spring 1 and a short lower leaf spring 2 having pin insertion holes at both ends are aligned, and a leaf spring insertion groove is formed at the end of the handle. Leaf springs 1 and 2 are attached to the provided grip handle 3.
is inserted, the stop pin 4 is inserted, the leaf springs 1, 2 and the handle 3 are fitted, and the outer ring 5 is fitted onto the outside. On the other hand, fit the other ends of the leaf springs 1 and 2 into the ball receiver 7, which has a ball 6 glued on one side and a leaf spring fitting groove on the other side, and insert the stop pin 4 into the ball receiver 7. This is a shoulder tap constructed by fitting the receiver 7 and fitting the outer ring 5 outward.

Since the present application is constructed as described above, the long upper leaf spring 1 and the short lower leaf spring 2 are fitted into the fitting grooves of the grip handle 3 and the ball receiver 7 by the fixing pins 4. The spring acts to push both ends of the leaf spring 2 outward, forming a curved shape as shown in the figure.

The curvature of the leaf springs 1 and 2 means that the position of the ball 6 on the longitudinal line of the grip handle 3 is on a diagonal line. Therefore, when hitting your shoulder, simply holding the grip handle 3 against your chest will cause the ball to hit your shoulder. 6 reaches the ball, and if you lift your arm slightly, the ball 6 will reach the back of your shoulder.

On the other hand, the composite spring stress of the leaf springs 1 and 2 based on the grip handle 3 is such that when the ball 6 is moved in a direction opposite to the curvature direction, the leaf springs 1 and 2 are bent in the direction opposite to the curvature, and the repulsive force increases. , acts to quickly return the ball 6 to its original position. Due to these effects,
Ball 6 returns quickly and hits the shoulder strongly, increasing the effect of hitting the shoulder. Therefore, if you strike with the same force as a conventional shoulder strike, you will need less movement back and forth. As a result, your arm won't get tired even if you play for a long time.

As described above, the present invention combines leaf springs of different lengths at the intermediate portion between the grip handle and the ball, so that the upper leaf spring forms a curved spring in which both ends of the lower leaf spring are pushed outward. Therefore, it has a shape that is easy to hit, resulting in a shoulder slap that reduces arm fatigue and enhances the hitting effect. The spring used in this application is an example of an applied application that is currently pending.
