Description

Mattress eyelets, sheet fastenings and mattresses Technical Field

[0001] The present disclosure relates to the technical field of mattresses, and in particular to a mattress air eye, a sheet fixing device with the mattress air eye, and a mattress equipped with the mattress air eye. Background Art

[0002] The air holes installed in the mattress allow the inside of the mattress to ventilate, which has a protective benefit on the core material inside the mattress. It also allows the mattress to ventilate and dissipate moisture faster after absorbing the moisture that penetrates into the mattress when the human body lies down, so as to keep the mattress dry and comfortable, thereby making the human body's sleeping experience on the mattress better.

[0003] However, conventional mattress eyelets are poorly adaptable to different core materials within mattresses, resulting in very limited air permeability. Mattress eyelets are typically installed on the mattress's vertical fabric. The methods for attaching the eyelet to the fabric can generally be categorized as either riveted or plug-in. The riveted eyelet method uses components on the front and back of the fabric that are riveted or plugged in. The back of the installed eyelet is flat, with no noticeable protrusion from the back of the fabric. The plug-in method uses a small tubular element, or insert, on the back of the eyelet. The insert is inserted through an opening in the fabric from the front, with its tail end positioned behind the fabric. The eyelet is positioned externally, in front of the front of the fabric, while a separate component is internally located (i.e., behind the fabric) to connect to the insert. The riveted eyelet method is less commonly used because it requires complex or numerous tools, is relatively cumbersome, and lacks aesthetic appeal.

[0004] The air flow channels of the air holes in conventional mattresses are easily blocked, so that the air flow channels cannot effectively provide ventilation for the interior of the mattress.

[0005] Riveted eyelets are only suitable for mattresses with significant voids within the core material adjacent to the eyelet (e.g., solid springs, 3D spacer fabric padding, etc.). For example, solid springs, composed of numerous supporting metal strips, have extensive voids within the spring body and lack fabric insulation between the eyelet and the eyelet, allowing airflow to and from the mattress relatively easily. However, if the mattress core adjacent to the eyelet is made of a relatively dense material (e.g., coir or latex padding) or fabric-covered pocket springs, the back of the installed rivet eyelet will be flat. This will result in the dense material or pocket spring directly blocking the eyelet's opening, rendering the rivet eyelet ineffective in providing ventilation. For example, "A mattress eyelet CN217633256U" belongs to the above-mentioned riveted eyelet. It has components on the front and back of the cloth that are assembled corresponding to each other. After installation, the back of the cloth is flat, that is, it has no obvious protrusion relative to the back of the cloth. As mentioned above, the riveted eyelet is only suitable for mattresses with adjacent internal core materials such as whole-mesh springs, 3D spacer fabric pads, etc. It is difficult to cope with mattresses with internal core materials of relatively dense materials or independent pocket springs covered with cloth.

[0006] Traditional plug-in eyelets are also difficult to use in mattresses with relatively dense core materials or fabric-covered pocket springs adjacent to the eyelet. Traditional plug-in eyelets feature a sleeve on the back, which is inserted through an opening in the fabric from the front, with its tail end positioned behind the fabric. The eyelet is then attached to a separate component built into the mattress, behind the fabric, and connected to the sleeve. The sleeve's tail end presses against the mattress core, stretching the fabric around it and maintaining a gap between the adjacent fabric and the core. The sleeve's hole corresponds to the air vent located outside the eyelet, just before the fabric's front. The sleeve's wall is a solid, continuous piece. For example, the mattress eyelet shown in "Airhole (AC04) CN304867872S" demonstrates the basic structural features of a traditional plug-in eyelet: its sleeve's wall is a solid, continuous piece. Therefore, the result of the traditional plug-in air eyelet's tail end being adjacent to the dense material or independent pocket spring is that the dense material or independent pocket spring will block the hole of the tail end of the plug-in air eyelet behind the plug-in air eyelet, thereby blocking the air flow of the plug-in air eyelet, so that the plug-in air eyelet cannot effectively perform its function of providing ventilation for the interior of the mattress.

[0007] Due to the problems with mattress air holes in the above-mentioned traditional technology, there are some defects in current mattress products. That is, if the core material inside the mattress is not a core material with a large number of significant gaps in the body, such as a whole-net spring, a 3D spaced fabric cushion, etc., then the installed mattress air holes cannot really and effectively play the role of ventilation, but only serve as a decoration; or simply cancel and do not install mattress air holes, but the internal core material of the mattress is a coir cushion, a latex cushion, an independent pocket spring and other materials that are denser or more closed, and in fact need more ventilation than a mattress with a whole-net spring or a 3D spaced fabric cushion as the core material, but no mattress air holes are installed.

[0008] Furthermore, there are illogical design considerations when integrating the functional structure of mattress eyelets with other mattress components. "A Detachable Mattress Breathable Fixing Device and Its Detachable Mattress CN106880220A" designs mattress eyelets as devices that can simultaneously secure a fitted sheet or the soft surface of the mattress. However, this functional integration is difficult to implement in practice. Fitted sheets typically have elastic bands at the four corners of the mattress's underside to fit over the four corners. Fitted sheets also ensure sufficient lower edge space to press against the mattress. This is a common structural design for commercially available fitted sheets. Therefore, designing mattress eyelets to simultaneously secure the fitted sheet is redundant. Potential applications are limited to providing consumers with a fitted sheet and mattress as a single unit, which offers no real advantages. As for the mattress toppers, while they are prone to getting dirty and potentially breaking, a more appropriate and widely adopted solution is a zippered removable top. When dirty, the toppers can be removed for washing, and when damaged, they can be replaced. Zippered toppers, in addition to the zippers at both ends, completely align their edges with the corresponding mattress edges, providing a secure and easy-to-use solution, something that non-zippered toppers struggle to achieve. In contrast, designing mattress eyelets to also secure the toppers effectively reduces their effectiveness, rendering such functional integration meaningless. Furthermore, the structure designed to secure the fitted sheet or mattress toppers is cumbersome, including detachable components that must be attached to the fitted sheet or mattress toppers. This makes both manufacturing and final product use unwieldy, lacking practical value. Summary of the Invention

[0009] The present invention provides a more breathable mattress air eye, which is used to be installed in a mattress to allow air to pass through the mattress. The installation location is usually the vertical cover of the mattress. The mattress air eye is placed inside the mattress (i.e., behind the front of the cover) through an opening in the cover. The built-in part includes an expansion part, which can press against the core material inside the mattress to expand the surrounding adjacent parts of the cover, so that a gap is maintained between the adjacent parts of the cover and the core material in the front-to-back direction (i.e., the depth direction, referred to as the longitudinal direction); the built-in part has a vertical direction (i.e., the vertical direction) and / or a horizontal direction (i.e., the horizontal direction). The built-in lateral airflow circulation structure is connected to the longitudinal air holes in the external part of the mattress air eyelet in front of the front side of the surrounding cloth; the built-in lateral airflow circulation structure makes the core material that the tail end of the expansion part will touch even if it is a relatively dense material or an independent pocket spring covered with cloth, and it will not hinder the mattress air eyelet from providing ventilation to the inside of the mattress, and compared with the traditional full-wall insert, the built-in lateral airflow circulation structure can make the air flow in and out of the mattress through the mattress air eyelet circulate more directly and efficiently, which can expand the air flow volume and enhance the breathability of the mattress air eyelet.

[0010] In a first aspect, the present disclosure provides a more breathable mattress air eye, wherein the mattress air eye includes an internal part and an external part, the external part is provided with a longitudinal air hole, the internal part is located behind the external part and connected to the external part, the internal part includes a longitudinally extending expansion part, and a built-in lateral airflow circulation structure is provided between the expansion part and the longitudinal air hole, and the built-in lateral airflow circulation structure allows air to circulate laterally through the longitudinal air hole.

[0011] In one possible implementation, the expansion portion is an insert tube, the insert tube hole of which corresponds to the longitudinal air vent, the insert tube is fixedly connected to the external portion, and the insert tube is provided with the built-in lateral airflow circulation structure, and the built-in lateral airflow circulation structure includes at least one of a built-in lateral airflow hole and a built-in lateral airflow notch;

[0012] The built-in lateral airflow hole is opened at the insert portion between the insert tail end and the external portion;

[0013] The built-in lateral airflow notch is opened at the tail end of the insert.

[0014] In a possible implementation, the rear portion of the insert is provided with the built-in lateral airflow notch, and the portion of the insert between the built-in lateral airflow notch and the external portion is provided with the built-in lateral airflow hole.

[0015] In one possible implementation, the built-in part includes a built-in mounting part, the built-in mounting part is provided with the expansion part, the built-in mounting part is mounted on the external part, and a built-in lateral open space, namely the built-in lateral airflow circulation structure, is formed between the expansion part and the longitudinal air vent.

[0016] In one possible implementation, the built-in part includes a built-in mounting part, the built-in mounting part is provided with a mounting part air vent corresponding to the longitudinal air vent, the built-in mounting part is provided with at least two of the expansion parts, the two expansion parts are respectively fixedly connected to the back of the built-in mounting part, and the interval between the two expansion parts forms a built-in lateral airflow gap, namely the built-in lateral airflow circulation structure.

[0017] In a possible implementation, the expansion portion is a guide plate, and the guide plate is fixedly connected to the external portion;

[0018] The front edge of the guide plate at least partially corresponds to the middle of the longitudinal air vent, or the longitudinal air vent is formed at adjacent external portions on both sides of the guide plate;

[0019] A built-in lateral open space, namely the built-in lateral airflow circulation structure, is formed between the guide plate and the longitudinal air vents, and buckles are provided on the side of the guide plate.

[0020] In the solution disclosed herein, the guide plate does not surround the back opening of the longitudinal air vent on the outside of the edge of the back opening of the longitudinal air vent like the insert. Instead, a lateral open space is built in behind the cloth, that is, inside the mattress, which is connected to the airflow of the longitudinal air vent. When the airflow inside the mattress flows laterally, at least part of the airflow will encounter the guide plate and be forced to turn toward the longitudinal air vent and flow out of the mattress, rather than flowing blindly laterally. When the airflow outside the mattress flows into the mattress through the mattress air holes, it will be divided into at least two airflows by the guide plate, and then at least part of the airflow of the two airflows will be forced to flow and diffuse laterally inside the mattress due to the guide plate. The guide plate can guide the flow direction of the airflow in and out of the mattress through the mattress air holes, thereby improving the ventilation effect of the mattress air holes.

[0021] In a possible implementation, the internal portion includes a ventilation cylinder, at least three guide plates surround the ventilation cylinder and are respectively fixedly connected to the outer wall of the ventilation cylinder, and the longitudinal ventilation hole is provided in the external portion between two adjacent guide plates;

[0022] The air vent hole is in air communication with the longitudinal air vent hole, or the external portion further defines the longitudinal air vent hole corresponding to the air vent hole.

[0023] In one possible implementation, the external part includes a front and rear double-layer structure with a cavity between the double-layer structures. The double-layer structures are respectively a back layer of the external part and a surface layer of the external part. The surface layer of the external part and the back layer of the external part are fixedly connected through the side wall of the external part. The back layer of the external part is provided with the longitudinal air vents, and the side wall of the external part is provided with external lateral air vents.

[0024] In a possible implementation, the built-in portion includes a built-in mounting part, which is provided with a mounting sleeve hole and an insert portion corresponding to the longitudinal air vent and the buckle, and the insert portion is fixedly connected to the inner side of the mounting sleeve hole and protrudes toward the longitudinal air vent.

[0025] In the solution disclosed in the present invention, since the guide plate does not surround the back opening of the longitudinal air vent on the outer side of the back opening edge of the longitudinal air vent like the insert tube, and the opening of the cloth is not necessarily a regular round hole, the inner edge of the cloth opening may block the longitudinal air vent, so the inner edge of the cloth opening that blocks the longitudinal air hole can be pushed open by the insert.

[0026] In a second aspect, the present disclosure provides a sheet fixing device with a mattress eyelet, wherein the sheet fixing device includes a mattress eyelet, and the mattress eyelet is the mattress eyelet described in the first aspect.

[0027] The solution shown in the present disclosure is that fixing the bed sheet is a common and widespread practical need of people when using a mattress. Integrating the mattress air eyelet and the bed sheet fixing device into one device and installing it on the mattress, thereby achieving both ventilation of the mattress interior and fixing of the bed sheet, is a more reasonable application design and more practical.

[0028] In a third aspect, the present disclosure provides a mattress equipped with mattress air eyes, wherein the vertical surface of the mattress is equipped with mattress air eyes, and the mattress air eyes are the mattress air eyes described in the first aspect; or, the vertical surface of the mattress is equipped with a sheet fixing device with mattress air eyes, and the sheet fixing device is the sheet fixing device described in the second aspect.
