Description

Technical Field

[0001] The utility model relates to the field of mattresses, in particular to a mattress with a double-sided connected detachable layer. Background Art

[0002] In order to enable a mattress to have a good sleeping experience in different seasons of hot and cold, some mattresses adopt a combined structure in which a detachable layer and a main mattress are attached to each other up and down. The upper and lower surfaces of the detachable layer are made of different fabrics suitable for summer and winter respectively, such as a plush surface and a cotton cloth surface for winter heat preservation, and a mat surface and an ice silk surface for summer cooling. During use, the mattress can be adjusted by changing the side of the detachable layer that is attached to the main mattress according to the season change. In order to make the detachable layer and the main mattress fit and fix firmly, a detachable connection structure is provided between the two for positioning. Common connections are buttons or straps. Since the detachable layer and the main mattress are only connected at the places where buttons or straps are provided, the formed positioning is a connection of a limited number of points. During use, the detachable layer will slide relative to the main mattress and shift, seriously affecting the experience of using the mattress. Content of the Utility Model

[0003] To solve the technical problem that the connection between the existing detachable layer and the main mattress is not firm, resulting in the detachable layer sliding and shifting relative to the main mattress and affecting the use experience, the utility model provides a mattress with a double-sided connected detachable layer. After the detachable layer and the main mattress are connected in place, they fit firmly and will not produce relative sliding and displacement, and the use experience of the mattress is good.

[0004] The technical solution adopted by the utility model to solve the technical problem: A mattress with a double-sided connected detachable layer, including a detachable layer and a main mattress that are attached to each other up and down. The two sides of the detachable layer are a cool side and a warm side respectively. A matching connection part is provided between the main mattress and the detachable layer so that the detachable layer can be turned over and attached to the main mattress. The feature is that the connection part includes a first chain belt and a second chain belt that are respectively arranged along the circumference of the main mattress and the circumference of the detachable layer. The first chain belt and the second chain belt are zipped up by a slider to form a closed zipper. When the detachable layer is turned over and attached to the main mattress, the first chain belt and the second chain belt are respectively inserted into a socket through a plug arranged in two opposite directions and inserted into the slider, so that the slider zips up the first chain belt and the second chain belt. By setting two circumferentially surrounding chain belts to form a closed zipper, the utility model enables the detachable layer and the main mattress to have a circumferentially continuous connection limit, thereby ensuring that the detachable layer firmly adheres to the main mattress and preventing the detachable layer from sliding relative to the main mattress and causing displacement, which affects the use of the mattress; when the detachable layer and the main mattress are connected, any one of the plugs can be inserted through the slider and into the socket between the first and second chain belts, which can close one end of the zipper. Then, by pulling the slider along the chain belt towards the other end, the closed locking between the two chain belts can be achieved. When the detachable layer is turned over and connected to the main mattress, the two plugs also take turns passing through the slider and inserting into the socket.

[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: one of the first and second chain belts is a one-way chain belt with a fixed opening and closing direction, the pull head is slidably set on the one-way chain belt, and the socket is set at the end of the one-way chain belt; the other of the first and second chain belts is a two-way chain belt that can be opened and closed in both directions, and the two oppositely set plugs are respectively set at the two ends of the two-way chain belt. One of the two chain belts is a one-way chain belt with a pull head and a socket, and the pull head can only slide along the chain belt from the end where the socket is located to the other end, and the other chain belt has a plug at each end. When the two chain belts are matched and closed, the socket at the end of the one-way chain belt and one of the two plugs at both ends of the two-way chain belt are always matched. When the socket and one of the plugs are plugged in place, the pull head slides from one side of the plug along the chain belt to the side of the other plug to be used to close the two chain belts; one of the two chain belts is on the main mattress, and the other is on the detachable layer. The detachable layer can be changed to fit the main mattress and connected with a zipper.

[0006] The one-way chain belt is provided with a stopper at the other end away from the socket to prevent the pull head from sliding out. The stopper can limit the pull head to prevent the pull head from sliding out along the chain belt, and when the pull head slides into place, it hits the stopper.

[0007] The two ends of the two-way chain belt are arranged in the middle of the edge of the main mattress or the detachable layer and are symmetrically centered. The socket on the one-way chain belt corresponds to one of the two ends of the two-way chain belt. The two ends of the two-way chain belt are in the middle of the edge of the detachable layer or the main mattress and are symmetrically centered. The edge can be a long side or a short side, ensuring that after the detachable layer is turned over, the two chains can be closed again to form a zipper closed along the circumferential direction. When the two ends of the two-way chain belt are not in the middle and symmetrically centered, the detachable layer cannot be closed again to form a zipper after it is turned over.

[0008] The detachable layer is provided with a moisture-absorbing pad and a heat-insulating pad, and the moisture-absorbing pad and the heat-insulating pad are respectively attached to the cold side and the warm side. The moisture-absorbing pad and the heat-insulating pad are respectively attached to the cold side and the warm side, wherein the moisture-absorbing pad is attached to the cold side for moisture absorption and perspiration in summer, and the heat-insulating pad is attached to the warm side for heat insulation and warmth in winter.

[0009] The moisture-absorbing pad is made of cloth or fiber flakes that absorbs moisture and perspiration, and the heat-insulating pad is made of glue-free cotton. The moisture-absorbing pad made of cloth or fiber flakes can effectively absorb human sweat and moisture, and can meet the work needs of moisture absorption and perspiration; the glue-free cotton is very soft, has no irritation to the human body, has the characteristics of strong warmth retention, and can meet the work needs of heat insulation and warmth retention.

[0010] The weight of the non-glue cotton is 150-250g / m 2 The weight of the glue-free cotton can meet the use requirements of the detachable layer. If the weight is too large, it will be difficult for the detachable layer to fit the main mattress, especially when the glue-free cotton needs to be pressed on one side of the main mattress. If the weight is too small, the insulation and warmth effect will be poor.

[0011] The cold side and the warm side, together with the adhered moisture absorption pad and heat insulation pad, are sewn and shaped through the quilting process. The quilting process can partition the cold side, the warm side, and other cushion layers in the inner sandwich of the two into evenly distributed small cells for firm positioning.

[0012] The cold side and the warm side are hemmed and sewn along the periphery of the detachable layer, and the second chain belt is arranged on the hem formed by sewing between the cold side and the warm side. Through the hemming and sewing, the cold side and the warm side are connected into one body along the periphery, which can not only effectively cover the frayed edges of both sides, but also be beautiful and durable, and can also reduce the contact between the edge of the detachable layer and the outside to prevent wear. It can be easily completed by machine, and the second chain belt is arranged on the hem where the two sides are butted.

[0013] A continuous binding strip is arranged along the peripheral edge of the top of the main mattress, and the first chain belt is arranged on the upper edge formed by the inner edge of the binding strip. The binding strip serves as a sealing protection along the periphery of the main mattress, which is not only beautiful, but also can be used as the installation position for setting the first chain belt. Since the first chain belt is on the upper edge formed by the inner edge of the binding strip in a circle, when the detachable layer and the main mattress are butted and attached, the first chain belt and the second chain belt are closed to form a zipper on the outer side of the detachable layer in a circle.

[0014] The utility model forms a zipper structure by setting two one-way chain belts and a two-way chain belt that are circumferentially surrounded and matched, so that the detachable layer forms a continuous connection and positioning between the circumferential main mattresses, ensuring that the detachable layer is firmly attached to the main mattress and avoiding the displacement of the detachable layer relative to the main mattress due to sliding, which may affect the use of the mattress. When the detachable layer is turned over and attached to the main mattress, the two plugs at both ends of the two-way chain belt are alternately butted with the sockets of the one-way chain belt, enabling the slider to slide and close the two chain belts to form a zipper. Further, the two chain belts can be interchanged positions on the detachable layer and the main mattress, and different cushion layers for moisture absorption, sweat discharge, heat insulation, and warmth preservation are also provided in the detachable layer.

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] As Figure 1 shown, the present utility model is a mattress with a double-sided connected detachable layer, which includes a detachable layer 2 and a main mattress 1 that are attached and connected up and down. The two sides of the detachable layer 2 are respectively a cool side 9 for summer use and a warm side 10 for winter use. Between the main mattress 1 and the detachable layer 2, through a matching connection part, the detachable layer can be attached and connected to the main mattress even after being turned over. The connection part includes a first chain belt 3 arranged along the circumference of the main mattress 1 and a second chain belt 4 arranged along the circumference of the detachable layer 2. The two chain belts are pulled together by a pull head 5 to form a closed zipper. When the detachable layer 2 is turned over and attached to the main mattress 1, one of the two reverse plug rods 8 passes through the pull head 5 and inserts into the socket 6, so that the pull head 5 pulls the first chain belt 3 and the second chain belt 4 to form a closed zipper. One of the first chain belt 3 and the second chain belt 4 is a one-way chain belt with a fixed opening and closing direction, the pull head 5 is slidably arranged on this one-way chain belt, and the socket 6 is arranged at one end of this one-way chain belt. The pull head can only open and close in a fixed direction on the one-way chain belt. The other of the two chain belts is a two-way chain belt that can be opened and closed in both forward and reverse directions, and the two reverse plug rods 8 are respectively located at the two ends of the two-way chain belt.

[0025] As Figure 3 and Figure 5 shown, the first chain belt 3 on the main mattress 1 is set as a one-way chain belt, and the second chain belt 4 on the detachable layer 2 is set as a two-way chain belt. This is used as an example to illustrate how the two chain belts are pulled together by the pull head 5 to form a closed zipper. The positions of the one-way chain belt and the two-way chain belt can also be interchanged. When in use, the detachable layer and the main mattress are connected, as Figure 7The two chain belts shown are described in detail. At this time, the plug at the lower end of the two-way chain belt on the drawing can pass through the pull head and insert into the socket, closing the starting end of the zipper. The plug at the upper end of the two-way chain belt is idle. Pull the pull head along the chain belt and slide it towards the other end to close and lock the connection between the two chain belts. When the pull head slides into place, there is a continuous circumferential positioning connection between the detachable layer and the main mattress, and the two fit firmly without relative sliding or displacement. One side of the cool side or warm side of the detachable layer faces upwards for use. When the detachable layer needs to be turned over, first unlock the zipper and remove the plug from the socket, turn the detachable layer over so that the warm side faces upwards, insert the previously idle plug into the socket, and the other plug is idle. Then pull the pull head along the chain belt again to slide, so that the two chain belts are closed and locked again. After the pull head slides into place, the detachable layer and the main mattress are connected circumferentially again, and the detachable layer and the main mattress fit firmly again. Thus, the detachable layer can be repeatedly turned over and fit with the main mattress, and there will be no sliding or displacement between the two.

[0026] Furthermore, in order to prevent the pull head 5 from sliding out of the one-way chain belt at the end away from the socket, a rabbet 7 is provided at the other end of the one-way chain belt away from the socket 6, and the pull head just abuts against the rabbet when it slides into place.

[0027] Furthermore, in order to enable the two chain belts to be smoothly matched and connected after the detachable layer is turned over, the two ends of the two-way chain belt are arranged in the middle section of the edge of the detachable layer 2 and are symmetrically centered, as Figure 3 and Figure 4 shown. The two plugs 8 of the two-way chain belt are symmetrically centered in the middle section of the short side of the detachable layer, as Figure 5 and Figure 6 shown. The socket 6 on the one-way chain belt is also in the middle section of the short side of the main mattress and corresponds to one of the two ends of the two-way chain belt.

[0028] Furthermore, in order to improve the comfort of using the detachable layer, as Figure 1 and 2 shown, a moisture-absorbing pad 11 and a heat-insulating pad 12 that fit together are also provided in the detachable layer 2. The moisture-absorbing pad 11 and the heat-insulating pad 12 are respectively attached to the cool side 9 and the warm side 10. Among them, the moisture-absorbing pad 11 is made of moisture-absorbing and sweat-wicking fabric or fiber floc, and the heat-insulating pad 12 is made of non-woven cotton with a gram weight of 150 - 250 g / m 2 ², preferably non-woven cotton with a gram weight of 200 g / m 2 ²; at the same time, the cool side 9 and the warm side 10 and the attached moisture-absorbing pad 11 and heat-insulating pad 12 are sewn and shaped through the quilting process. A continuous hem tape 13 is provided at the top edge periphery of the main mattress 1, and the first chain belt 3 is arranged at the upper edge of the opening surrounded by the inner edge of the hem tape 13. The cool side 9 and the warm side 10 are hemmed and sewn along the periphery of the detachable layer 2 in a circle, and the second chain belt 4 is arranged on the hem formed by sewing between the cool side 9 and the warm side 10. When the detachable layer and the main mattress are fitted and butted, the first chain belt forms a zipper by closing with the second chain belt in a circle outside the detachable layer.
