Description

[Detailed explanation of the idea] The present invention relates to a shape retaining device for shoes.

In the past, various ideas have been made for shape-retaining devices for shoes, and among them, there are known shapes and structures that can be made into shape-retaining devices by simply cutting and bending a single flat plate. . However, although shape-retaining devices inserted only into the instep can prevent the instep from collapsing, they cannot prevent deformation of the shoe opening, making it difficult to maintain the shape of the shoe as a whole; A shape-retaining device that is inserted over the entire length of the shoe has been proposed, but it is still far from being sufficient and cannot completely prevent the deformation of the shoe opening from opening laterally. This invention consists of one flat plate,
An object of the present invention is to provide a shoe shape retaining device that retains the shape of the shoe over its entire length.

The structure of the present invention is that, in a shoe shape-retaining device integrally formed from a flat plate, an upper surface part is connected to the inside of each shoe opening edge of two side sections that are approximately in the shape of the side surface of a shoe, and each shoe shoe edge is They are each formed into an outwardly convex arc shape and are connected at their front ends, and a reinforcing piece is provided in a tongue shape on a part of the edge of the instep of one side, and the reinforcing piece is connected to the side. are bent downward with the creases at the edges of the shoe opening and the edge of the instep, respectively.

The side part has a shape that is almost similar to the side shape of the shoe, and includes the collar part in the side shape of the shoe, the upper part that slopes down in front of the collar part, the bottom part, and the rear end of the collar part that rises from the rear end of the bottom part. They roughly correspond to the heel portions leading to the
It is surrounded by a shoe opening 5, an upper edge 6, a bottom edge 7, and a heel edge 8.

The present invention will be explained based on examples. A flat plate such as cardboard or a plastic sheet is used as the material for the shape retainer. Figure 1 is a perspective view of the embodiment, Figure 2 is a perspective view of the embodiment.
The figure is a developed view of FIG. 1, and FIG. 3 is a side view of FIG. 1.

The developed view shown in FIG. 2 will be explained. Two side surfaces 1, 1, which are approximately in the shape of the side surfaces of a shoe, are formed around shoe edges 5, 5, upper edges 6, 6, bottom edges 7, 7, and heel edges 8, 8, The two side parts 1,1 are connected at the front ends 4 of their shoe opening edges 5,5. The two cuff edges 5, 5 have an arcuate curved shape convex outward to the right or left, respectively, and the inner side surrounded by the edge connecting the two cuff edges 5, 5 and the rear end is the upper surface part 2. It is. Although not shown, two shoe opening edges 5, 5
The rear end may be connected. A tongue-shaped reinforcing piece 3 is extended from the side surface 1 with the midway point on the upper edge 6 of one side surface 1 and the front end 4 of the shoe opening edge 5, that is, the upper end of the upper edge, as both ends of the base. Set up Reinforcement piece 3
One edge is common to a part of the upper edge 6 of the other side surface 1 extending from the front end 4 of the shoe opening edge 5.
The portion where the reinforcing piece 3 is extended on the shoe opening edges 5, 5 and the upper edge 6 of one side portion 1 is the bent portion, and the other edges are the cut portion. Front end of shoe opening edge 4
Since the two edges of the back part meet at an acute angle, a small circular hole is made to provide tear resistance. From the bottom edges 7, 7 of the side parts 1, 1 to the heel edges 8,
The part that moves to 8 is formed round with a large curve, and
Holes 10, 10 are bored at the rear and slightly upper part of the side surface. The developed body formed in this way using a flat plate is
As shown in the figure, the side plates 1, 1 and the reinforcing piece 3 are bent downward using the shoe opening edges 5, 5 and the instep edge 6 as folds to obtain a shape retaining device. The reinforcing piece 3 extends toward the upper side of the instep edge, and its width in the front and back direction is determined as appropriate in consideration of the reinforcing function, and the length in the up and down direction is equal to the lower edge 9.
The shape is determined so that the inner sole of the shoe comes into contact with the inner sole of the shoe. When inserting the shape-retaining device into the inside of the shoe, press both side parts 1, 1 slightly inward and squeeze the shape-retaining device, and insert the front part into the upper part of the shoe as far as it will go until it no longer moves forward.
Next, the heel edges 8, 8 are slid into contact with the inner surface of the heel of the shoe, and the bottom edge is brought into contact with the midsole surface.
Since the lower part of the heel edge is rounded, it is possible to push the heel into the shoe without any resistance. The inside of the shoe looks like this: The upper parts of the laces edges 6, 6 abut on the inner surface of the laces, the upper parts of the heel edges 8, 8 abut on the inner surface of the heel part, and the side parts 1, 1 widen downward and touch the bottom edges 7, 8. 7 is in contact with the midsole surface or the lower periphery of the inner surface of the upper, and the upper edges 6, 6 and the heel edges 8, 8 stretch the shoe in the front-rear direction via the upper surface 2. The reinforcing piece 3 has its lower edge 9 in contact with the inner bottom surface. When taking out the shape retainer from inside the shoe, the user engages his fingers in the holes 10, 10 in the side parts 1, 1 and pulls out the shape retainer.

The effects of the present invention are as follows. Since the two side surfaces 1, 1 are shaped almost in the shape of the side surfaces of a shoe, the two upper edges 6, 6 receive deformation force at the edge of the upper, but the shape retention effect is greater than when the two upper edges 6, 6 receive deformation force at the flat surface. Excellent, because the instep edges 6, 6 and heel edges 8, 8 are in contact with the instep and heel of the shoe, the opening of the shoe is supported in the front-rear direction and does not deform, and the entire shoe is supported. It has a shape-retaining effect. Since the tongue-shaped reinforcing piece 3 is extended to the upper edge 6 of one side part 1 so that its lower edge 9 touches the insole, even if a load is applied to the upper edges 6, 6 from above, The two side parts 5, 5 are reinforced to increase resistance and shape retention effect. The upper surface portion 2 has arch-shaped shoe opening edges 5, 5 connected at the front end portion 4 and convex outward, respectively.
are the two edges in the front and back direction, and the side parts 1, 1 are bent downward using the shoe opening edges 5, 5 as folds, so as shown in FIG. Together with the two edges (edges of the shoe opening), the upper surface 2 has excellent resistance against compressive force in the front and back direction, and the side surfaces 1, 1 have a strong resistance to the folded side surfaces 1, 1. In response to the inward force applied to the surface, elasticity is exerted that tends to expand the side surfaces 1, 1 outward. The strength of the upper surface part 2 is effective for fully maintaining the shape of the shoe opening by strongly pushing it in the front-back direction, and the elasticity that tends to expand outward of the side parts 1 is 1 and 1 are expanded downward to the end and the bottom edges 7 and 7 are positioned near the periphery of the midsole or near the lower periphery of the upper to keep the shape-retaining device stable inside the shoe, resulting in a shape-retaining effect for the entire shoe. In addition to ensuring that
Since the side portions 1, 1 are prevented from expanding outwardly by the bottom edges 7, 7, the upper portions of the upper portion edges 6, 6 are in particular always in contact with the inner surface of the upper portion of the shoe, and from the uppermost When a load is applied to the vicinity of the front end 4 of the shoe opening rim, which is susceptible to the load, the side surfaces 1, 1 bulge outward in a convex shape between the top and bottom, buffering the load, preventing buckling, and providing elastic support. Demonstrates shape effect. Furthermore, when the shoe opening edges 5, 5 are formed in a straight line in the front-rear direction, the bottom edges 7, 7 of the two folded side surfaces 1, 1 remain in contact with the insole, and the upper surface 2 is formed along the fold. However, the above-mentioned arcuate structure prevents the upper surface portion 2 from swinging from side to side, thereby stabilizing and ensuring the shape-retaining effect of the entire shoe. In addition, since the present invention is formed by cutting a single flat plate into one piece, it is easy to arrange materials, there are no parts, and the processing process and handling are simple. The idea was to create a side part 1 with a shape similar to the side of a shoe.
1, the inside of each shoe opening edge 5, 5 is the upper surface part 2, and the reinforcing piece 3 is extended to the instep edge 6 of one side part 1, so the developed view shows the side part 1, 1 and the upper surface part 2.
The shape is such that the reinforcing piece 3 is extended into the empty triangular part in front of the butterfly-shaped ring, which is made, and the overall ring is approximately rectangular, so the yield from the flat plate is not wasted and is efficient.

As detailed above, the present invention, with the above-mentioned configuration, ensures the preservation of the shape of the upper and cuff of the shoe (the preservation of the shape of the cuff naturally includes the preservation of the shape of the side surface of the instep). It has an excellent shape-retaining effect over the entire shoe, and has economical effects such as good material usage efficiency and easy processing and handling.
