Abstract

(57) [Summary] [Problems] There are inconveniences in adjusting winding strength and loosening after winding. SOLUTION: Engagement short pieces 2 and 3 are respectively attached to one end surface side and the other end back side of an elastic rubber band 1 having an appropriate length and width to be wound around an arm portion. Locking pieces 4 and 4a for engaging and disengaging from the engaging short pieces 2 and 3 are attached to the front and back surfaces of the central portion of the, respectively. A locking structure in which the rubber band 1 is wound around the arm and locked.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an elastic rubber band locking structure in which an elastic rubber band is easily wound around an arm by adjusting the strength thereof, and is locked and fixed.

[0002]

[Prior art]

 Conventionally, in order to wrap the rubber band around the arm, it is necessary to hold the end of the rubber band and the stopper provided at the end with both hands, and fix it with a single winding. Also, in order to increase the strength of the tightening, a method was adopted in which the rubber bands were wound in layers, and finally the ends of the rubber bands were folded and fixed between the wound rubber bands.

[0003]

[Problems to be solved by the invention]

 In order to obtain a sufficient winding strength around the arm portion, a lap winding was performed. However, the strength of the tightening was different each time the double winding and triple winding were performed, and the desired strength could not be adjusted. In addition, since the rubber band is merely wound, there is a drawback that the rubber band is “displaced” and loosened. Furthermore, in the case of a handicapped person or when wrapping it around his or her own arm, both hands cannot be used and only one hand can be used, so that it is not easy to adjust the tightness in this state.

[0004]

[Means for Solving the Problems]

 In view of such circumstances, the present invention has been devised to address this problem, i.e., it has an appropriate length and width to be wrapped around the arm, and has one end on the front side and the other end on the back side. Attach the engaging short piece which becomes an engaging portion of an appropriate length, and further attach and mold a rectangular locking piece having an appropriate length and width to be separated from the engaging short piece on each of the front and back surfaces of the central portion. A stretchable rubber band having a stretchable rubber band which can be easily wrapped by adjusting the strength of the stretchable rubber band with the use of the engaging short piece and the locking piece. It provides a stop structure.

[0005]

[Embodiment of the invention]

 The present invention is a locking structure for an elastic rubber band that easily wraps around the arm. Reference numeral 1 denotes an elongated elastic rubber band having an appropriate length and width that wraps around the arm. The elastic rubber band 1 has, at one end on the front side, an engaging short piece 2 serving as an engaging portion having an appropriate length and width, and an engaging short piece formed on the back surface on the other end side in the same manner as described above. 3 and further, rectangular upper and lower engaging pieces 4 and 4a having an appropriate length and width to be engaged with and disengaged from the engaging short pieces 2 and 3, respectively, are attached to the front and back surfaces of the central portion of the elastic rubber band 1. It is molded. Next, in order to wind the elastic rubber band 1 around the arm portion by using the engaging short pieces 2 and 3 and the locking pieces 4 and 4a, the elastic rubber band 1 is moved to a position where the arm portion is to be wound with one hand. It is wound twice, and the engaging short piece 2 attached to one end is temporarily locked and fixed to the locking piece 4. Further, the other remaining rubber band 1 is overlapped and wound with one hand while adjusting the strength. Then, the engaging short piece 3 at the end is locked and locked on the locking piece 4a to complete the winding.

[0006]

[Effect of the invention]

 In the present invention, when the elastic rubber band 1 is wound around the arm portion using the engaging short pieces 2 and 3 provided at both ends and the locking pieces 4 and 4a provided at the center portion, It can be easily wound and locked with only one hand, and the strength of the winding can be freely adjusted by adjusting the locking position. There are effects such as holding.
