Description

[Technical Field]

[0001] The present invention relates to a heel pad that is crescent-shaped in plan view and has a guide portion and left and right holding portions integrated together, and is built into the heel portion of a shoe that can be put on without using a shoehorn. [Background technology]

[0002] Shoes that can be put on without a shoehorn include those that have a deformable heel that is temporarily deformed to allow the foot to be inserted into the opening, and those that have a heel core built into the heel that allows the foot to slide into the opening (see Patent Document 1). The shoe disclosed in Patent Document 1 has a built-in heel core (reinforcing member) that is crescent-shaped in plan view and that combines a hard guide section (the section that abuts the rear of the heel) that acts as a shoehorn for the foot that is inserted into the opening, and soft left and right support sections (the sections that abut the left and right sides of the heel) that hold the heel in place from the left and right. As a result, the heel core disclosed in Patent Document 1 prevents the guide section from tipping forward, and the left and right support sections wrap around the foot, firmly securing the heel (see Patent Document 1

[0016] ). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-053040 Summary of the Invention [Problem to be solved by the invention]

[0004] The heel pad disclosed in Patent Document 1 only allows the left and right support parts to move left and right around the linear boundary between the guide part and the support part. The left and right support parts have a triangular front end shape with a downward-sloping upper edge intersecting with a horizontal lower edge, and the lower edge is fixed to the sole, limiting their freedom of movement. This means that the support parts can only hold the foot in a predetermined orientation, making it difficult to better encase the foot for various users. Therefore, we investigated the shape of the support parts that can better encase the foot for a heel pad that is built into shoes that can be put on without a shoehorn, and that has a crescent-shaped shape in a plan view and integrates the guide part and left and right support parts. [Means for solving the problem]

[0005] As a result of these studies, we have developed a heel core for shoes that is crescent-shaped in plan view, with the guide section and left and right retaining sections integrated together, and that features the front end portions of each of the left and right retaining sections being convex in side view. The convex front end portion in side view may have its front edge protruding forward from the lower edge, and is preferably arc-shaped in side view. If the guide section and the left and right retaining sections have different hardnesses, a boundary is formed between them. If the guide section is hard and the left and right retaining sections are soft, the boundary between the hard guide section and the soft left and right retaining sections may be concave in side view, with the middle section facing backward in the vertical direction. The hard guide section may be thicker than the left and right retaining sections, or may have a separate reinforcing surface laminated thereon. The concave boundary in side view may have its middle section protruding backward from the upper and lower sections, and is preferably arc-shaped in side view. [Effects of the Invention]

[0006] In the heel core of the present invention, the front end portions of the left and right retaining portions are convex in side view, so that the front edges are spaced apart from the lower edges, allowing the left and right retaining portions to have front end portions that can deform freely, allowing the retaining portions to better encase the foot. In particular, by making the front end portions of the retaining portions arc-shaped in side view, there are no corners at the front end portions, improving the tactile sensation of the foot being wrapped around. Furthermore, by making the boundaries between the hard guide portion and the soft left and right retaining portions concave in side view and set back toward the rear, the left and right retaining portions can deform three-dimensionally, allowing the retaining portions to better encase the foot. In particular, by making the boundaries arc-shaped in side view, the deformation of the left and right retaining portions changes continuously in the vertical direction, allowing the foot to be held more firmly.

[Figure 2] FIG. 1 is a right side view of the shoe of this example, with its outline virtually displayed. [Figure 3] FIG. 10 is a rear view of the shoe of this example, with its external shape virtually displayed. DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1 to 3, the heel pad 2 of the present invention is built into the upper 13 of the heel portion 11 of a shoe 1 that can be put on without using a shoehorn. The heel pad 2 of this example is a resin member that is crescent-shaped in plan view and is composed of a guide portion 21, which is a curved surface material similar to a shoehorn, and left and right retaining portions 22, which are curved surface materials that protrude forward from the guide portion 21. The guide portion 21 and the left and right retaining portions 22 are molded integrally, and further, a reinforcing curved surface material similar in shape to the guide portion 21 is provided. 212 are overlapped, and a boundary 23 is provided between the guide portion 21 and the left and right holding portions 22.

[0009] The guide portion 21 has an upper edge that follows the rear edge of the shoe opening 12 and has a guide surface 211 facing upward. The guide surface 211 serves to place and slide the heel of the foot (not shown) and guide the foot into the shoe 1. The guide portion 21 in this example is made of overlapping curved surface members for reinforcement. 212 Therefore, even if the guide surface 211 is raised, the guide portion 21 will not bend or deform due to the heel of the foot placed on it. The guide portion 21 of this example, which has a raised guide surface 211, makes it possible to provide a shoe 1 that is easier to put on.

[0010] The holding portion 22 is a curved surface material for reinforcement. 212 The front end 221 is formed in an arc shape in side view by left and right convex pieces extending the curved surface material of the guide part 21 excluding the left and right retaining parts 22. The lower edges of the guide part 21 and the left and right retaining parts 22 are continuous straight lines, and all are fixed to the sole 14. Here, since the front end 221 of each of the left and right retaining parts 22 is formed in an arc shape in side view, most of the front edge protrudes forward from the front end of the lower edge of the retaining part 22, creating a part that can deform without being restrained by the lower edge. This allows the front end 211 of the retaining part 21 that has deformed to fit the foot to better envelop the foot.

[0011] The heel pad 2 in this example is a reinforcing curved surface material. 212 The front edges of the support parts 21 form the boundary 23 with the support parts 22. In this example, the boundary 23 is arc-shaped in side view, with the middle part in the up-down direction protruding rearward. The left and right support parts 22, which are relatively soft compared to the guide part 21, deform forward from the boundary 23. At this time, because the boundary 23 is arc-shaped in side view, the left and right support parts 22 can easily deform to fit the foot. This allows the front end parts 211 of the support parts 21, which have deformed to fit the foot, to better encase the foot. [Explanation of symbols]
