Description

Technical Field

[0001] This utility model relates to the field of household products technology, and in particular to a gel pad. Background Technology

[0002] Play mats are essential for infants and toddlers to crawl and play, providing an activity area by being laid on the ground. Most mainstream play mats are made of foam materials such as EVA and XPE. While these materials absorb impact through elasticity, providing basic support, their cushioning effect is limited. Infants and toddlers are prone to bumps and bruises when they fall because the impact is not fully dispersed. Secondly, foam materials have poor breathability and thermal conductivity, easily accumulating heat and causing stuffiness in summer. Additionally, the surface is often hard, resulting in a poor experience for infants and toddlers and potentially causing skin irritation.

[0003] Therefore, designing a gel pad that has good resilience to effectively cushion the skin, good temperature regulation to provide a comfortable cooling sensation during use and avoid discomfort caused by excessive temperature differences, while using medical-grade materials for high safety, is a technical problem that designers and developers need to solve.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] This invention provides a gel pad 10 that possesses both good resilience for effective cushioning and excellent temperature regulation capabilities, providing a comfortable cooling sensation during use and preventing discomfort caused by excessive temperature differences. Furthermore, it is made of medical-grade materials, ensuring high safety. (See also...) Figure 1 and Figure 2 The gel pad 10 includes a main body layer 100, a gel layer 200, and a capping layer 300.

[0031] The main body layer 100 has a connecting surface 110 and a placement surface 120, while the gel layer 200 has an inner connecting surface 210 and an outer surface 220. The gel layer 200 is bonded to the connecting surface 110 of the main body layer 100 via the inner connecting surface 210, and the capping layer 300 covers the outer surface 220. The gel layer 200 is adhesive; when the inner connecting surface 210 is in contact with the connecting surface 110, the gel layer 200 and the main body layer 100 can be tightly bonded together. When the capping layer 300 covers the outer surface 220, the gel layer 200 and the capping layer 300 can be tightly bonded together. In this way, the main body layer 100, the gel layer 200, and the capping layer 300 can be connected into a single structure, while ensuring that the relative positions of the three layers remain stable, facilitating subsequent processing. Understandably, because the gel layer 200 is sticky, dust may adhere to it and it is not easy to clean. Prolonged use may cause skin discomfort to users. The sealing layer 300 completely covers the gel layer 200, which effectively avoids this situation and improves the user experience.

[0032] In addition, see Figure 3 , Figure 4 and Figure 5 The connecting surface 110 has a reserved area 111 and an installation area 112. The reserved area 111 is located around the installation area 112. The installation area 112 is used to bond the gel layer 200. The capping layer 300 completely covers the outer surface 220 and is bonded to the reserved area 111. The capping layer 300 is a thermoplastic material, which can be tightly bonded to the main body layer 100 by hot-pressing. That is, the surface of the capping layer 300 can be melted by high temperature and high pressure, thereby physically bonding with the main body layer 100 and achieving an efficient connection between the two. However, the gel layer 200 is not thermoplastic and cannot be tightly bonded to the main body layer 100 by hot-pressing.

[0033] By attaching the capping layer 300 to the reserved area 111, a sealed cavity is formed between the capping layer 300 and the main body layer 100. The gel layer 200 is located in the sealed cavity, thereby isolating the gel layer 200 from the air and preventing the gel layer 200 from being oxidized due to long-term contact with the air, thus extending the service life of the gel pad 10.

[0034] In one embodiment, the cover layer 300 is bonded to the reserved area 111 by means of adhesive bonding, hot pressing, or other methods, resulting in a smooth structure without protruding parts, thus ensuring a good user experience. Of course, the cover layer 300 can also be bonded to the reserved area 111 by other methods.

[0035] See also Figure 2 and Figure 3The gel layer 200 has multiple protrusions 230, which are evenly spaced on the outer surface 220. These protrusions 230 increase the friction between the gel pad 10 and the user's skin or clothing, thus providing an anti-slip effect and improving the safety of the gel pad 10. Simultaneously, the protrusions 230 can provide slight stimulation to the user's skin, helping to enhance the user's sensory perception.

[0036] In one embodiment, see [reference] Figure 8 The main body layer 100 has an annular side surface 130, and the capping layer 300 extends to the annular side surface 130. At this time, the capping layer 300 can be bonded to the reserved area 111 while also bonding to at least part of the annular side surface 130, further enhancing the stability of the connection between the main body layer 100 and the capping layer 300, effectively avoiding the problem of easy separation between the capping layer 300 and the main body layer 100. At the same time, it makes the sealing performance of the sealed cavity formed between the capping layer 300 and the main body layer 100 better, thereby further preventing air from entering the interior of the gel pad 10, further preventing the gel layer 200 from contacting air and causing oxidation, and further extending the service life of the gel pad 10.

[0037] The working principle of the gel pad 10 of this utility model will be explained below in conjunction with the above structure. Please refer to the following: Figures 1 to 8 :

[0038] During the processing, the main body layer 100 of the predetermined size can be processed first. Then, the inner surface 210 of the gel layer 200 is bonded to the installation area 112. Since the gel layer 200 itself has a certain degree of adhesion, no other adhesive is needed. Next, the capping layer 300 completely covers the outer surface 220 of the gel layer 200. Finally, the capping layer 300 is bonded to the reserved area 111, thereby fixing the main body layer 100, the gel layer 200 and the capping layer 300 into an integrated structure.

[0039] The gel mat 10 provided by this utility model is suitable as a baby crawling mat. Existing crawling mats are usually made of foam materials such as EVA and XPE, which have limited cushioning effect; secondly, foam materials have poor breathability and poor thermal conductivity, which easily accumulates heat in summer, causing stuffiness; at the same time, the surface is relatively hard, which may cause skin discomfort to infants and young children, resulting in a poor experience for infants and young children. This application solves the above problems through a three-layer structure design. Specifically, firstly, the gel layer 200 has the dual characteristics of "slow rebound + high elasticity". When subjected to pressure (such as human body weight, object impact), it can evenly disperse the impact force. Compared with the rigid rebound of foam materials, it can reduce the local pressure feeling, which is especially suitable for infants and young children crawling; secondly, the heat conduction speed of the gel is controllable, and it will not produce a "chilling cold" like metal or ice products, bringing a comfortable coolness when used, avoiding discomfort caused by excessive temperature difference; thirdly, the medical-grade gel layer 200 does not contain harmful chemicals such as formaldehyde, benzene, and heavy metals, and is not prone to releasing irritating odors, thus having better safety.

[0040] Chinese utility model patent application CN 204930939U, entitled "Gel Seat Cushion," discloses a gel seat cushion comprising a cushion body and a gel layer mounted on the cushion body. The gel layer is wrapped between two layers of TPU film and forms multiple raised, block-like protrusions. The cushion body has a double-layered leather structure, with foam filling around its perimeter. The gel layer is installed in the center of the cushion body, and a non-woven fabric is placed between the gel layer and the cushion body. The gel seat cushion provided by this utility model has the advantages of good cooling and heat-relieving performance and excellent comfort. However, in the prior art, the gel layer and the cushion body cannot be directly bonded together, the installation method is complex, and the connection stability is poor.

[0041] Compared with the prior art, the present invention solves the above problems by directly bonding the gel layer 200 to the main body layer 100 and providing a reserved area 111. Specifically,

[0042] Firstly, the gel pad 10 is simplified to three layers, which are quickly assembled through the adhesiveness of the gel layer 200 itself. The connection between the three layers can be achieved without adding other structures, thus reducing the processing and assembly costs.

[0043] Secondly, by setting a reserved area 111, it is convenient to directly heat-press the capping layer 300 and the main body layer 100, making the connection reliable and effectively avoiding the problem of easy separation between the gel layer 200 and the main body layer 100. At the same time, the structure is smooth and has no protruding parts, ensuring the user's physical experience.

[0044] Thirdly, by directly thermally pressing and bonding the cover layer 300 with the reserved area 111, the sealing performance at the connection between the cover layer 300 and the main body layer 100 is effectively ensured, thereby guaranteeing the sealing performance of the enclosed cavity formed between the cover layer 300 and the main body layer 100. The gel layer 200 is located within the enclosed cavity, thus effectively isolating the air from the gel layer 200, preventing the gel layer 200 from being oxidized due to long-term exposure to air, and extending the service life of the gel pad 10.

[0045] Refer to Figure 3 , the gel layer 200 has a width L1, and the width of the reserved area 111 is L2, where 0.054L1 ≤ L2 < 0.057L1. For example, 0.054L1 = L2, 0.055L1 = L2, 0.0565L1 = L2, 0.057L1 = L2, etc. When L1 and L2 have this relationship, the stability of the connection between the gel layer 200 and the cover layer 300 is effectively ensured, avoiding both the situation of waste of materials caused by an overly large width of the reserved area 111 and the situation of unstable connection caused by an overly small width of the reserved area 111.

[0046] In one embodiment, the cover layer 300 is configured as a TPU film. The TPU film has high safety, is non-toxic and environmentally friendly, and is also highly durable. Even if scratched by sharp objects, it is not easily broken. In the case of needing cleaning and disinfection, it can be directly cleaned and disinfected with alcohol, diluted bleach, etc. The TPU film will not be corroded, facilitating cleaning and disinfection. Understandably, due to the thermoplasticity of the TPU film, the cover layer 300 can be adhered to the reserved area 111 by thermally pressing and bonding. By applying high temperature and high pressure, the surface of the TPU film is melted, thereby enabling the TPU film to physically bond with the main body layer 100 and achieving an efficient connection between the two.

[0047] Anti-slip patterns (not shown in the figure) are provided on the placement surface 120 of the main body layer 100, and the anti-slip patterns are used to increase the friction coefficient. In actual use scenarios, the anti-slip patterns can increase the friction coefficient between the main body layer 100 and the floor, tiles, etc., so that the main body layer 100 will not easily slide, preventing the user from falling due to the unstable center of gravity caused by the sliding of the main body layer 100.

[0048] Exemplarily, the anti-slip patterns can be configured as anti-slip grooves opened on the placement surface 120. For example, the anti-slip grooves can be in the shape of a "hui" character, wavy, etc.

[0049] Exemplarily, the anti-slip patterns can be configured as uneven structures provided on the placement surface 120.

[0050] Combined with reference to Figure 6 and Figure 7The protrusion 230 is pyramidal in shape, with a base side length W and a height H, where 0.3W ≤ H ≤ 0.6W. For example, 0.3W = H, 0.4W = H, 0.56W = H, 0.6W = H, etc. This relationship between W and H effectively ensures the anti-slip function of the protrusion 230. At the same time, the pyramidal shape of the protrusion 230 can effectively stimulate the user's skin. Understandably, if H is too large, the user is prone to falling due to the protrusion tipping over, and the tip of the protrusion 230 is too sharp, resulting in a poor tactile feel. If H is too small, the protrusion 230 becomes nearly flat, resulting in an insignificant anti-slip function and insufficient stimulation of the user's skin.

[0051] In an embodiment not shown in the figure, the protrusion 230 is cylindrical. This results in a smooth structure with no sharp edges, reducing the risk of injury to the user from bumps and knocks. Furthermore, the cylindrical shape of the protrusion 230 ensures even stress distribution, making it less prone to damage and easier to manufacture.

[0052] In one embodiment, the main body layer 100 is made of solid cotton. Solid cotton has a certain degree of heat insulation, which can effectively block the cold air from the floor (especially ceramic tiles and marble), preventing users from getting cold due to the cold ground when crawling. At the same time, it has good support and anti-slip properties. The high-density solid cotton structure is compact, so when users crawl or stand on it, the main body layer 100 made of solid cotton is not easily dented or deformed due to force, providing stable support and preventing it from sliding easily, thus preventing users from losing their center of gravity and falling due to the slippage of the main body layer 100.

[0053] In one embodiment, the main body layer 100 is made of solid cotton, and the cover layer 300 is constructed as a TPU film. When the cover layer 300 is bonded to the reserved area 111 of the main body layer 100 by hot pressing, the high temperature and high pressure cause the surface of the TPU film to melt and physically combine with the surface fibers and pores of the solid cotton, effectively ensuring the stability of the connection between the two.

[0054] In summary, the gel pad 10 of this invention has good resilience, which can effectively achieve a cushioning effect, and also has good temperature regulation capabilities, which can bring a comfortable cooling sensation during use and avoid discomfort caused by excessive temperature difference. At the same time, it is made of medical-grade materials, which has a high degree of safety.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
