Description
Technical Field
[0001] This utility model relates to the field of furniture, and in particular to a detachable cushion structure and a chair. Background Technology
[0002] As an important component of a sofa, seat cushions generally consist of a foam block and a cushion cover. Seat cushions on chairs are mostly single-sided soft cushions. In summer, additional cooling mats or bamboo mats are needed, but their smooth surfaces make them prone to slipping, warping, or even falling off, making them inconvenient to use. Furthermore, most existing sofa cushions and seats are a single, integral structure, meaning the entire cushion cannot be disassembled or replaced. Over time, the cushion easily becomes dirty or deformed, making repair and replacement difficult.
[0003] The purpose of this invention is to provide a detachable seat cushion structure and seat. The seat cushion can be removed from the seat for cleaning. When installing, the corresponding surface should be facing upwards according to the season, which increases the adaptability of the seat. Utility Model Content
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a detachable seat cushion structure, comprising: a first seat cushion, a second seat cushion, a first side strap, a second side strap, an elastic band, and a connector. The first side strap is disposed at both ends of the first seat cushion, and the second side strap is disposed at both ends of the second seat cushion. A first pre-drilled hole is provided through the middle of the first side strap, and a second pre-drilled hole is provided through the middle of the second side strap. One end of the elastic band is disposed inside the first pre-drilled hole, and the other end of the elastic band is disposed inside the second pre-drilled hole. The connector is disposed in the middle of the elastic band. Two stitching lines are provided at the center of the elastic band, and the two stitching lines are stitched together to fold the elastic band in half.
[0005] Preferably, the first seat cushion includes a velvet cover and a filling material, wherein the filling material is a vacuum-compressible sponge core.
[0006] Preferably, the second cushion comprises a cooling mat and a 3D mesh fabric, wherein the edge of the cooling mat is sewn to the edge of the 3D mesh fabric.
[0007] Preferably, both the first side strip and the second side strip are woven strips, with both ends of the first side strip sewn to the first seat cushion, both ends of the second side strip sewn to the second seat cushion, and both ends of the elastic band sewn to the middle of the first side strip and the middle of the second side strip, respectively.
[0008] Preferably, the seat frame is further provided with symmetrical hanging points at the lower end of the seat frame. The hanging points are elongated and the connectors are detachably connected to the hanging points in a one-to-one correspondence.
[0009] Preferably, the connector is a hook and loop fastener, with the loop side symmetrically arranged in the middle of the elastic band, and the hook side of the hook and loop fastener correspondingly arranged at the hanging points.
[0010] Furthermore, the hanging point is a plane, and the hook side of the Velcro is contained within the center of the hanging point.
[0011] Preferably, the connector is a hook plate, one end of which is symmetrically provided with hooks, and the other end of which is provided with an elongated through hole. The elastic bands are inserted one-to-one through the elongated through holes so that the hook plate is T-shaped.
[0012] Furthermore, the hanging point is an arc surface, and the central angle of the arc surface is 180°.
[0013] This utility model also provides a seat, including a seat frame and a detachable seat cushion structure as described above. The seat frame includes legs and a crossbeam. The two ends of the crossbeam are respectively disposed at the upper ends of two adjacent legs. The crossbeam is a plate. The plane in which the crossbeam is located is vertically arranged. The lower end of the crossbeam protrudes downward to form an arc-shaped curved surface. The upper end and lower end of the crossbeam are symmetrically arranged. The crossbeam forms the aforementioned hanging point. The lower end of the crossbeam forms the aforementioned arc surface.
[0014] The beneficial effects of this utility model are as follows: both ends of the first and second seat cushions are provided with elastic bands, and the connectors at the ends of the elastic bands can be installed on the seat or removed from the seat. When installing, the first or second seat cushion can be flipped up to be used according to the season, which increases the adaptability of the seat and makes it easy to clean.
