Description

Technical Field

[0001] The utility model belongs to the technical field of shoemaking materials, in particular to an elastic shoe stretcher used for shoe heels. Background Art

[0002] There are many shoes on the market that are easy to put on and take off, i.e., quick to put on, such as:

[0003] Japanese Patent Application No. 2022-139151 uses a slanted slide formed by a shoe support extending backward and upward from the heel to allow the heel to slide into the shoe, and then uses an elastic gasket to clamp the heel so that it is not easy to fall off. The upper extension of the shoe support in this invention is straight and narrow. When the heel is stepped on and the force is not applied properly, the heel will bend backward and downward, and the effect of sliding into the shoe can not be achieved;

[0004] In addition, the shoe tree is made of a hot-melt adhesive composite sheet, which is easily deformed when exposed to high temperatures, and has poor toughness and is easily broken when exposed to external forces. In order to increase the strength, it can only be multi-layered, which makes the workmanship complicated in the actual shoemaking production process, increases the shoemaking cost, and is not conducive to promotion and application.

[0005] The shoe stretcher is made of hard material, and the method of fixing it to the heel is just to clamp it between the upper and the lining. It fails to establish an effective fixed connection with the midsole plate and the sole of the overall supporting part of the shoe, and the firmness is not high, resulting in the gradual decrease in the stability of the heel during daily wear.

[0030] Example 1

[0031] See attached Figure 1-2 The elastic shoe stretcher for the heel of a shoe of the present embodiment includes a shoe stretcher body 100, which is composed of a first arc portion 110, a second arc portion 120 and a third arc portion 130. The upper end of the second arc portion 120 is connected to the first arc portion 110, and the lower end is connected to the third arc portion 130. The second arc portion 120 has a smooth transition with the first arc portion 110 and the third arc portion 130.

[0032] In this embodiment, a plurality of bottom structures 140 are distributed and connected along the lower bottom of the third arc-shaped portion 130 , and the bottom structure 140 is bent and fixed between the midsole plate and the sole at the position of the sole.

[0033] The first arc portion 110 , the second arc portion 120 and the third arc portion 130 of this embodiment are all located between the upper and the inner lining of the heel.

[0034] The top of the first arc portion 110 of this embodiment is inclined upward in a direction away from the heel, the vertical cross-section of the first arc portion 110 is arc-shaped, and the middle portion of the first arc portion 110 is concave toward the middle to form an arc tray.

[0035] The second arc portion 120 of this embodiment is an open arc structure. The horizontal width of the second arc portion 120 is smaller than the horizontal width of the first arc portion 110 , and the horizontal opening width of the second arc portion 120 is smaller than the horizontal width of the third arc portion 130 .

[0036] The upper portion of the third arc portion 130 of this embodiment is a hemispherical shell structure, the lower portion of the third arc portion 130 transitions smoothly downward, and the outer contour of the end of the third arc portion 130 away from the sole is larger than the outer contour of the end close to the sole.

[0037] The thickness of the shoe tree body 100 of this embodiment gradually decreases from the center to the edge.

[0038] The shoe support body 100 is made of TPU material, wherein TPU has the characteristics of good elasticity, wear resistance, shape recovery, toughness, and strong thermoplasticity. The bottom structure 140 has the advantages that the thickness should not be too thick and can be bent, so as to more effectively fix the heel of the shoe and prevent it from falling off and deforming. The shoe support body 100 is installed in the back of the shoe. When the human foot wears the shoe, the front end of the foot is inserted into the shoe first, and the heel is pressed on the arc tray of the heel of the present invention, and the heel is pressed downward with force. The first arc portion 110 of the present embodiment is stressed, causing the second arc portion 120 to expand outward due to deformation due to the stress, and the heel slides down along the arc tray and smoothly passes through the expanded second arc portions, thereby sliding into the third arc portion 130 to complete the shoe wearing action. When the heel slides into the third arc portion 130, the pedaling force acting on the second arc portion 120 disappears instantly, and the second arc portion 120 instantly returns to its original shape due to the rebound force, clamping the heel so that it is not easy to pull out, thereby achieving the effect of preventing the heel from falling off.

[0039] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
