Description

Technical Field

[0001] The utility model belongs to the field of dance, and more specifically, particularly relates to a foot presser for developing the instep. Background Art

[0002] Dance instep pressing is a basic dance training process, which is to press the ankle ligaments and toe joint ligaments further apart to form a bulge in the instep joint, making the arch of the foot higher, so that the dancer's legs can form beautiful arc lines in accordance with the foot shape, improve the stability of the half toe, and make the dance movements of the foot more expressive and musical. At present, traditional dance instep pressing training usually uses manual pressing or a foot presser wrapped with a bandage on the foot for auxiliary pressing. During the manual pressing process, not only do the two dancers need to cooperate with each other, but the intensity of continuous pressing and the foot posture are also difficult to control, which can easily cause the foot to turn inward during training and cause ankle ligament strain. In addition, traditional auxiliary foot pressers are mostly fixed curved structures, which cannot be flexibly adjusted according to the size of the feet and limbs of different dancers.

The dancer's foot is passed through the elastic band 1. At this time, the dancer's heel is placed on the upper side of the heel pad 6, and the ankle is attached to the memory foam wrapped outside the ankle pad 2. The elastic band 1 is tied tightly around the ankle and the upper side of the calf to prevent the knee from bending. The adjustment knob 12 is manually turned, and the adjustment knob 12 drives the adjustment threaded rod 16 to rotate in the groove of the bearing plate 4. Since the threaded through hole of the convex plate on the lower side of the bracket 8 is engaged and connected to the outer thread surface of the adjustment threaded rod 16, the adjustment threaded rod 16 is brought The movable bracket 8 is adjusted and moved forward or backward along the groove of the carrying plate 4, so that the pressure rod 10 carried by the bracket 8 is docked with the dancer's instep pressing position, and then the correction knob 11 is manually turned, and the correction knob 11 drives the two-way threaded rod 17 to rotate.
