Description

Technical Field

[0001] This utility model relates to insoles, and more particularly to an elastic and warm insole. Background Technology

[0002] Ordinary insoles are very easy to compress and deform, lose elasticity, and cannot effectively absorb impact (especially when running or jumping). Even with high-quality materials, excessive pressure in certain areas may cause them to collapse too quickly. Long-term lack of effective cushioning will increase the impact load on the lower limb joints, accelerate wear and fatigue, and make them uncomfortable to wear. Therefore, we propose an elastic and warm insole. Utility Model Content

[0003] The main objective of this invention is to provide an elastic, warm insole to solve the problems raised in related technologies.

[0004] To achieve the above objectives, according to one aspect of the present invention, an elastic thermal insole is provided, comprising an upper insole, a middle insole, and a lower insole. An elastic support portion is installed on the lower insole, and an air inlet is provided on the side of the lower insole. An air inlet tube is inserted into the air inlet to fill the elastic support portion with gas, thereby forming elastic support for the entire insole.

[0005] As a preferred embodiment of this invention, the surface of the upper pad is provided with a number of flexible protruding small balls, and the interior of the upper pad is provided with a number of upper vent holes.

[0006] As a preferred embodiment of this invention, the inner part of the middle pad is provided with a plurality of ventilation holes, and the inner part of the middle pad is filled with a heating material.

[0007] As a preferred embodiment of this utility model, the interior of the lower pad is provided with a plurality of lower vent holes, and the lower vent holes, middle vent holes and upper vent holes correspond one-to-one.

[0008] As a preferred embodiment of this invention, the surface of the lower pad is provided with a plurality of air bladder grooves.

[0009] As a preferred embodiment of the present invention, the elastic support includes a plurality of airbags, which are fixedly installed in the airbag grooves, and the plurality of airbags are interconnected by connecting hoses.

[0010] As a preferred embodiment of this invention, the airbag is annular, and the outermost end of the airbag is provided with an inflation hole, with the inflation hole and the inflation port facing each other.

[0011] As a preferred embodiment of this utility model, a plurality of elastic connecting members are fixedly connected between the upper pad and the lower pad.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention involves inserting an inflation tube into an inflation port and inflating the airbag. The gas enters the inflation hole of the outermost airbag through the inflation port and then into the outermost airbag. When the outermost airbag is full of gas, the gas enters the other airbags sequentially through the connecting hose until all the other airbags are full. At this point, the fully inflated airbags can provide elastic support for the feet. Furthermore, the airbags can be inflated at any time if the gas level is insufficient, which can effectively reduce the impact load on the lower limb joints, reduce fatigue, and make the shoes more comfortable to wear.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] like Figures 1 to 3 As shown, according to one aspect of the present invention, an elastic thermal insole is provided, comprising an upper insole 1, a middle insole 2 and a lower insole 3. An elastic support portion is installed on the lower insole 3, and an air inlet 33 is provided on the side of the lower insole 3. An air inlet tube is inserted into the air inlet 33 to fill the elastic support portion with gas, thereby forming an elastic support for the entire insole.

[0023] The upper pad 1, middle pad 2, and lower pad 3 are fixed together by adhesive or by sewing.

[0024] As a preferred embodiment, the surface of the upper pad 1 is provided with a plurality of flexible protruding small balls 11, and the interior of the upper pad 1 is provided with a plurality of upper vent holes 12.

[0025] As a preferred embodiment, the inner pad 2 is provided with a plurality of ventilation holes 21, and the inner pad 2 is filled with a heating material, which can provide a warming effect for the entire insole. The heating material can be modified cellulose or protein fiber.

[0026] As a preferred embodiment, the lower pad 3 is provided with a plurality of lower vent holes 31 inside, and the lower vent holes 31, the middle vent holes 21 and the upper vent holes 12 correspond one-to-one.

[0027] As a preferred embodiment, the surface of the lower pad 3 is provided with a plurality of air bladder grooves 32.

[0028] In a preferred embodiment, the elastic support includes a plurality of airbags 34, which are fixedly installed in the airbag groove 32, and the plurality of airbags 34 are interconnected by connecting hoses 35.

[0029] As a preferred embodiment, the airbag 34 is annular, and the outermost end of the airbag 34 is provided with an inflation hole, with the inflation hole and the inflation port 33 facing each other.

[0030] Several elastic connectors 4 are fixedly connected between the upper pad 1 and the lower pad 3. The elastic connectors 4 can be made of elastic rubber pillars. The surfaces of the upper pad 1 and the lower pad 3 are provided with insertion holes at the positions of each elastic connector 4. The two ends of the elastic connector 4 are fixedly inserted into the two insertion holes respectively. The interior of the middle pad 2 is provided with through holes at the positions of each insertion hole. The elastic connector 4 passes through the through holes. Under normal conditions, the upper pad 1 and the lower pad 3 are in close contact with each other. When inflated, the airbag 34 bulges and pushes up the middle pad 2 and the upper pad 1. At this time, it will cause the elastic connector 4 to deform and stretch slightly. The setting of the elastic connector 4 ensures the connection between the upper pad 1 and the lower pad 3 without affecting the normal use of the airbag 34.

[0031] In use, insert the inflation tube into the inflation port 33 and inflate it. The gas will enter the inflation hole of the outermost airbag 34 through the inflation port 33 and then enter the outermost airbag 34. When the outermost airbag 34 is full of gas, the gas will enter the other airbags in sequence through the connecting hose 35 until all the other airbags are full of gas. At this time, the fully inflated airbag 34 can provide elastic support for the foot. As long as the airbag is not full, it can be inflated at any time, which can effectively reduce the impact load on the lower limb joints, reduce fatigue, and make it more comfortable to wear. After inflation, insert the sealing plug into the inflation port 33.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
