Description

Technical Field

[0001] This application relates to a high heel, and more particularly to a low-noise spring high heel with an elastic heel that can relieve foot fatigue and is easy to maintain. Background Technology

[0002] High heels are a popular shoe choice for modern women because they make them appear taller and more elegant. However, high heels present several problems: they can damage the feet and knees, primarily because the small contact area with the ground and high pressure make the feet prone to injury and deformation; the hard soles of high heels also cause significant damage to the knees; and climbing stairs in high heels causes even greater damage to the legs and knees.

[0003] Patent document No. 201820282415.6 discloses a spring-loaded high heel shoe. Based on a regular high heel shoe, it adds an elastic mechanism, integrating the heel with the mechanism. When walking in this type of spring-loaded high heel shoe, the elastic mechanism provides cushioning between the heel and the ground, reducing damage to the feet and knees. While satisfying women's desire for beauty, it allows for comfortable walking up and down stairs or leisurely strolls after meals without fatigue, offering both comfort and aesthetic appeal. However, this type of spring-loaded high heel shoe has the following drawbacks: the elastic mechanism is externally attached to the heel, resulting in an unattractive appearance; the connection is not secure, and the elastic mechanism is prone to detachment during use, posing a safety hazard; the elastic mechanism generates noise during compression and expansion, affecting the wearing experience.

[0004] To address the aforementioned technical problems, the applicant applied for Chinese invention patents, publication numbers CN 115778055 A and CN 115921714 A, for two types of spring-loaded high heels. Both designs incorporate an elastic mechanism within a sleeve to prevent detachment and include a guide mechanism to ensure directional sliding between the upper sleeve and the lower slide block. However, these designs have the following drawbacks: 1. The elastic mechanism and guide mechanism frequently collide with the first guide groove on the first sliding sleeve, increasing noise; 2. The upper sleeve is fixedly connected to the heel seat, making disassembly difficult after assembly, and replacement is challenging after the spring loses its elasticity; 3. The lower sleeve has a large stroke, resulting in a bumpy feeling when walking; 4. The fixing part and heel seat are screwed together, making them prone to unraveling during walking, causing the fixing part and lower sleeve to detach together.

[0005] Therefore, in order to further improve the comfort of wearing them, as well as the ease of installation and maintenance, it is necessary to design an improved spring high heel. Summary of the Invention

[0006] The purpose of this application is to propose a low-noise spring high heel that is easy to maintain, has low noise when walking, reduces the feeling of bumps by limiting the travel of the sleeve, and is easy to install.

[0007] This application is implemented as follows: a low-noise spring high heel shoe that is easy to maintain, including a shoe body and a sole fixed to the bottom of the shoe body. A heel seat is connected to the rear end of the sole. An insertion port is provided at the bottom end of the heel seat. A column is integrally connected to the center of the insertion port. A limit head is integrally connected to the lower end of the column. A heel is inserted into the insertion port. A limit hole is provided on the side of the heel. A limit rod is provided in the limit hole and passes through the limit hole and is connected to the column. An end cap is connected to the limit rod and covers the limit hole. A rubber sleeve is wrapped on the limit rod between the end cap and the column. A spring is provided in the heel to cushion the movement of the heel up and down.

[0008] The heel includes a hollow sleeve with an open upper end, a limiting hole is formed on the side wall of the sleeve, and a hollow insertion rod is provided at the center of the upper end face of the bottom surface of the sleeve, with the lower end of the insertion rod forming an insertion hole on the lower end face of the bottom surface of the sleeve.

[0009] The upper end of the spring is sleeved outside the limiting head and touches the lower end face of the column, while the lower end of the spring is sleeved outside the insertion rod and touches the inner bottom surface of the sleeve.

[0010] A soft top sheet is inserted into the underside of the bottom surface of the sleeve. A top sheet nail is integrally set on the upper surface of the top sheet. The top sheet nail is inserted into the sleeve through the insertion hole. The top sheet nail and the insertion hole are interference fit, which fixes the top sheet under the bottom surface of the sleeve.

[0011] The outer wall of the sleeve has a plane, and the limiting hole is opened on the upper part of the plane. Correspondingly, the cross-section of the insertion port and the cross-section of the sleeve are both circular.

[0012] A soft washer is placed on the upper end of the sleeve, and a sealing ring is fitted onto the upper end.

[0013] When the limit rod touches the upper end of the limit hole, the uppermost end of the sleeve is inside the insertion port, and at this time the sleeve is at its lowest stroke.

[0014] A screw hole is provided on the side wall of the column, and the limiting rod is screwed into the screw hole. The end cap is located outside the limiting hole. A connecting rod is provided on the inner end face of the end cap. The connecting rod is connected to the limiting rod, and the outside of the connection is covered with a rubber sleeve.

[0015] The limiting rod is a hollow rod with one open end. The outer wall of the limiting rod has an external thread that matches the screw hole. The closed end of the limiting rod is screwed into the screw hole, and the open end faces outward. An internal thread is provided on the inner wall of the cavity of the limiting rod. The connecting rod of the end cap has an external thread that matches the aforementioned internal thread. The external thread of the connecting rod is screwed into the internal thread of the limiting rod.

[0016] The limiting rod is a solid rod with an external thread on its outer wall that matches the screw hole. One end of the limiting rod is screwed into the screw hole. A cavity connecting rod with an open inner end is provided on the inner end face of the end cap. An internal thread matching the aforementioned external thread is provided on the inner wall of the cavity of the connecting rod. The internal thread of the limiting rod is screwed into the external thread of the connecting rod.

[0017] By implementing the above technical solutions, this application achieves elastic cushioning in high heels, eliminating the impact sensation when walking in them and protecting the feet and knees. Simultaneously, the heel-heel seat insertion structure of this application is stable, preventing the heel from rotating during use, reducing the risk of detachment, and extending its service life. Furthermore, the cooperation of the limiting rod and limiting hole ensures directional sliding between the sleeve and the insertion port, while the use of rubber sleeves, sealing rings, and washers reduces noise. Moreover, this application is easy to assemble and disassemble; simply removing the limiting rod separates the heel from the heel seat. A decorative leather layer is provided on the exterior of the heel seat and sleeve, giving the appearance of this invention the same as commonly seen high heels on the market, achieving a good aesthetic effect. The elastic heel is not easily noticeable, further facilitating the promotion of this application. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] Example: Figure 1-3 As shown, the easy-to-maintain low-noise spring high heel includes a shoe body 1 and a sole 4 fixed to the bottom of the shoe body 1. A heel seat 2 is connected to the rear end of the sole 4. An insertion port 2-1 is opened at the bottom end of the heel seat 2. A column 2-2 is integrally connected to the center of the insertion port 2-1. A limiting head 2-3 is integrally connected to the lower end of the column 2-2. A heel 3 is inserted into the insertion port 2-1. A limiting hole 3-3 is opened on the side of the heel 3. A limiting rod 8 is provided in the limiting hole 3-3 and connected to the column 2-2. An end cap 9 is connected to the limiting rod 8 and covers the outside of the limiting hole 3-3. A rubber sleeve 10 is wrapped on the limiting rod between the end cap 9 and the column 2-2. A spring 6 is provided in the heel 3 to cushion the movement of the heel 3.

[0026] Furthermore, the heel 3 includes a hollow sleeve 3-1 with an open upper end, a limiting hole 3-3 is formed on the side wall of the sleeve 3-1, and a hollow insertion rod is provided at the center of the upper end surface of the bottom surface of the sleeve 3-1, with the lower end of the insertion rod forming an insertion hole 3-2 on the lower end surface of the bottom surface of the sleeve 3-1.

[0027] Furthermore, the outer wall of the sleeve 3-1 has a flat surface, and the limiting hole 3-3 is formed on the upper part of this flat surface. Correspondingly, the cross-section of the insertion port 2-1 and the cross-section of the sleeve 3-1 are both chamfered. This structure is both aesthetically pleasing and prevents the sleeve 3-1 from rotating, allowing it to only move up and down.

[0028] Furthermore, a soft washer 3-5 is placed on the upper port of sleeve 3-1, and a sealing ring 3-4 is fitted over the upper port. The sealing ring 3-4 not only seals the gap between the upper part of sleeve 3-1 and the socket 2-1, preventing dust and other debris from entering the socket 2-1, but also creates a soft contact between the socket 2-1 and the outer wall of sleeve 3-1, thereby reducing noise. The washer 3-5 similarly creates a soft contact between the upper port of sleeve 3-1 and the upper closed surface of socket 2-1, thus reducing noise. The outer diameter of the column 2-2 should be smaller than the diameter of the inner cavity of sleeve 3-1 to avoid contact between the column 2-2 and the inner wall of sleeve 3-1. The sealing ring 3-4 can be replaced by a metal ring to increase wear resistance, but this will result in slightly more noise.

[0029] The lower stroke of sleeve 3-1 depends on the distance from the limit rod 8 to the upper end of the limit hole 3-3. When the limit rod 8 touches the upper end of the limit hole 3-3, the uppermost end of sleeve 3-1 should be inside the insertion port 2-1. At this time, sleeve 3-1 is at the lowermost stroke.

[0030] The upper stroke of sleeve 3-1 depends on the distance from the limiting rod 8 to the lower end of the limiting hole 3-3. When the limiting rod 8 touches the lower end of the limiting hole 3-3, the uppermost end of sleeve 3-1 should be located in the upper part or the uppermost side of the insertion port 2-1. At this time, sleeve 3-1 is in its uppermost stroke. In this case, when sleeve 3-1 is not in contact with the bottom surface, that is, when sleeve 3-1 is in its lowermost stroke, the distance between the upper end of sleeve 3-1 and the upper closed surface of insertion port 2-1 is greater than the distance from the limiting rod 8 to the lower end of the limiting hole 3-3.

[0031] The upper stroke of sleeve 3-1 may also depend on the depth of insertion port 2-1. When sleeve 3-1 is not in contact with the bottom surface, that is, when sleeve 3-1 is at its lowest stroke, if the distance between the upper end of sleeve 3-1 and the upper closed surface of insertion port 2-1 is less than the distance between the limiting rod 8 and the lower end of the limiting hole 3-3, then the upper stroke of sleeve 3-1 is determined by the depth of insertion port 2-1.

[0032] Furthermore, the upper end of spring 6 is sleeved on the outside of the limiting head 2-3 and contacts the lower end face of the column 2-2, while the lower end of spring 6 is sleeved on the outside of the insert rod and contacts the inner bottom surface of the heel 3. The limiting head 2-3 and the insert rod limit both ends of spring 6 to prevent the upper and lower ends of spring 6 from shifting laterally when compressed, which would cause spring 6 to fold and lose its elasticity.

[0033] A soft top cover 7 is inserted into the underside of the bottom surface of the sleeve 3-1. A top cover tack 7-1 is integrally formed on the upper surface of the top cover 7. The top cover tack 7-1 is inserted into the sleeve 3-1 through the insertion hole 3-2, and the top cover tack 7-1 and the insertion hole 3-2 are interference-fitted, thereby fixing the top cover 7 to the underside of the bottom surface of the sleeve 3-1. A decorative leather layer is provided on the heel seat 2 and the outside of the sleeve.

[0034] Furthermore, a screw hole is provided on the side wall of column 2-2, and the limiting rod 8 is screwed into the screw hole. The limiting rod 8 is a hollow rod with one open end. An external thread matching the screw hole is provided on the outer wall of the limiting rod 8. The closed end of the limiting rod 8 is screwed into the screw hole, and the open end faces outward. An internal thread is provided on the inner wall of the cavity of the limiting rod 8.

[0035] Furthermore, the end cap 9 is located outside the limiting hole 3-3, and a connecting rod is provided on the inner end face of the end cap 9. The connecting rod has an external thread that matches the aforementioned internal thread, and the connecting rod is screwed into the cavity of the limiting rod 8.

[0036] In another embodiment of this application, the limiting rod 8 is a solid rod, and an external thread matching the screw hole is provided on the outer wall of the limiting rod 8. One end of the limiting rod 8 is screwed into the screw hole.

[0037] Furthermore, the end cap 9 is located outside the limiting hole 3-3, and a cavity connecting rod with an open inner end is provided on the inner end face of the end cap 9. An internal thread matching the aforementioned external thread is formed on the inner wall of the cavity of the connecting rod, and the outer end of the limiting rod 8 is screwed into the inner cavity of the connecting rod. In this structure, the rubber sleeve 10 is wrapped around the connecting rod.

[0038] The two connection methods described above for connecting rods and limiting rods 8 allow the end cap 9 to be fixed to the column 2-2 and the limiting hole 3-3 to be concealed. To ensure a good seal and reduce noise, a layer of rubber can be provided on the inner end face of the end cap 9 to form a sealing layer, through which the aforementioned connecting rods protrude. The sealing layer not only seals the gap between the end cap 9 and the outer wall of the sleeve 3-1, preventing dust and other debris from entering the sleeve 3-1 through the limiting hole 3-3, but also allows for soft contact between the end cap 9 and the outer wall of the sleeve 3-1, thereby reducing noise.

[0039] like Figure 2 As shown, during installation, several screw holes are provided on the upper surface of the heel seat 2. The heel seat 2 is fixedly connected to the sole 4 by fixing screws 5. Then, the spring 6 is placed into the sleeve 3-1, and the upper part of the sleeve 3-1 is inserted into the socket 2-1, so that the upper end of the spring 6 is sleeved on the limiting head 2-3. Then, the sleeve 3-1 is pushed upward so that the screw hole on the column 2-2 is within the range of the limiting hole 3-3. Then, the limiting rod 8 is screwed to the screw hole, and finally the end cap 9 is connected to the limiting rod 8.

[0040] When worn while walking, as the bottom surface 7 of the sleeve 3-1 contacts the ground, the sleeve 3-1 gradually moves upward until it reaches its highest position and stops. During this process, the force between the sole of the foot and the ground is buffered by the spring 6, reducing damage to the feet and knees. As the foot is lifted, the sleeve 3-1 begins to move downward under the action of the spring 6 until it reaches its lowest position, limited by the limiting rod 8. During this process, the upper part of the sleeve 3-1 is restricted by the insertion port 2-1 and will not rotate. At the same time, the middle part of the sleeve 3-1 is restricted by both the limiting hole 3-3 and the limiting rod 8 and cannot rotate. Therefore, the sleeve 3-1 can only move in a straight line, thus ensuring stability during walking.

[0041] The above technical features constitute the embodiments of this application, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.
