Description

Technical Field

[0001] The utility model relates to the field of seating, in particular to a novel cover and a seat. Background Art

[0002] Household seats can be seen everywhere in life. For the purpose of protecting the seat back from tidying, such seats usually need to be covered with a detachable cover on the seat back support plate, so that the seat back support plate can always be kept tidy through the process of removing and washing the cover and covering the cover; therefore, in order to realize the detachable function, a zipper is provided at the opening position of the cover to close the cover, but the existing cover has many defects when used.

[0003] Since the chair has a backrest and a seat, the two cover openings covering the backrest and the seat need to be connected to corresponding zippers to close the cover openings at different positions. This requires at least two pull tabs connected to the zipper locks on the chair. The pull tabs can drive the locks to complete the closing of the cover openings under external force. However, after the cover is closed, the pull tabs at the backrest and seat of the chair will be exposed at the outer ends of the cover openings, which not only affects the appearance of the chair, but may also cause the pull tabs to be hooked with external debris, causing the cover opening to be accidentally opened. When the seats are mass-produced, the backrest and the seat require at least two pull tabs to be connected to the locks, which increases the production cost of the cover and affects the economy of the cover.

[0004] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Summary of the invention

Implementation

[0040] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0042] like Figure 1-10 As shown, the utility model has multiple implementation modes, and the specific implementation modes are as follows:

[0043] Embodiment 1: This embodiment provides a new type of cover, which can be covered on a seat support plate or a back support plate, which is usually made of leather or cloth. The cover includes a cover body 2 with an opening and a zipper assembly connected to the opening. The lock head 6 on the zipper assembly is connected to a pull tab 4 in a detachable manner. After the pull tab 4 is connected to the lock head 6, it can be pulled under the action of an external force to open or close the opening of the cover body 2. After the lock head 6 is pulled into place, the pull tab 4 can be removed from the lock head 6.

[0044] Furthermore, the cover includes an open cover body 2 and a zipper assembly connected to the opening, the chain assembly includes at least two sub-zippers, the opening is divided into at least two sub-areas extending along its own length direction, each sub-area is correspondingly connected to a sub-zipper, the sub-zipper is connected to a lock 6 that can close the zipper itself by sliding, the locks 6 on all sub-zippers are all in an empty state, and are respectively connected to a pull tab 4 and then pulled to gradually close the opening of the cover body 2; when the cover divides the opening into multiple sections for the purpose of matching with the seat, the advantage of the detachable connection between the pull tab 4 and the lock is further magnified, so that the zipper lock 6 at the cover opening no longer needs to be connected to multiple exposed pull tabs, which simplifies the structure of the cover opening and improves the practicality and aesthetics of the cover.

[0045] Furthermore, the opening is divided to avoid the support rod of the seat back, so the cover body 2 is provided with a left-right symmetrical notch B, the opening spans the notch B, and forms two starting ends at the junction of the opening and the cover body 2; the opening is bounded by the notch B, and the cover body 2 opening is divided into a middle area D between the notches B and a side area E between the notch B and the starting end; each sub-zipper of the zipper assembly includes a side zipper 3 connected to the side area E, and a front zipper 5 connected to the middle area D, the front zipper 5 and the side zipper 3 are both connected to a lock head 6 that can close the zipper by sliding by themselves, and the lock heads 6 of the front zipper 5 and the side zipper 3 share the same pull tab 4, and after all the lock heads 6 are pulled into place, the lock heads 6 of the front zipper 5 and the side zipper 3 are staggered along the length direction of the zipper assembly; so that the lock heads 6 of the zipper at the opening of the cover do not need to be connected to the corresponding pull tab, which simplifies the zipper structure and makes the appearance of the cover look neater.

[0046] Further, if Figure 4a , Figure 4b As shown, since ordinary lock heads 6 need to be connected to zipper pull tabs for pulling, but the exposed and shaking zipper pull tabs affect the appearance of the cover, and are also easily hooked and pulled with the outside world, affecting the fixing effect of the cover on the chair back. Therefore, when the cover body 2 is opened and closed, the pull tab 4 is first connected to the lock head 6 of the side zipper 3, and the pull tab 4 drives the lock head 6 to slide to complete the locking of the side area E by pulling; then it is removed from the lock head 6 of the side zipper 3 and connected to the lock head 6 of the front zipper 5, and the pull tab 4 drives the lock head 6 to slide again to complete the locking of the middle area D by pulling; the detachable pull tab 4 does not need to be connected to the corresponding pull tab on the lock head 6, but the lock heads 6 at different positions are pulled through the detachable structure to close the opening of the cover body 2, which not only simplifies the appearance of the cover opening, but also further reduces the probability of the zipper being accidentally pulled open, making the covering effect of the cover on the chair back 1 more stable.

[0047] Further, if Figure 3bAs shown, in order to ensure the disassembly and assembly speed of the pull tab 4 and the lock head 6, so as to improve the efficiency of closing the opening of the cover body 2, the pull tab 4 includes a holding portion and a hanging portion 42, a hanging gap 46 is formed between the holding portion and the hanging portion 42, and a hanging ear 61 is provided on the upper end surface of the lock head 6. The hanging portion 42 is hooked or separated from the hanging ear 61 through the hanging gap 46, so that the pull tab 4 is connected or separated from the lock head 6; the holding portion is rotatably connected with a rotating portion 41, and the rotating portion 41 is connected to the lock head 6 by a rotating shaft 43 provided on the mounting portion and a torsion spring ( The end position of the hanging portion 42 is provided with a limiting portion 45, and the rotating portion 41 can be elastically rotated to abut or separate from the limiting portion 45 to close or open the hanging gap 46, so that the pull tab 4 can be connected and disassembled on the lock head 6 of the zipper assembly; by elastically abutting the rotating portion 41 on the pull tab 4 with the limiting portion 45, the disassembly of the pull tab 4 and the lock head 6 is simplified to a simple pressing process of the rotating portion 41, so that the connection and disassembly process of the pull tab 4 and the lock head 6 at each position is faster and more convenient.

[0048] Further, if Figure 1 As shown, the mask body 2 is divided into a first body 21 and a second body 22 by the opening; the avoidance section 31 bypassing the gap B means that the avoidance section 31 is divided into a separation section facing the first body 21 and a connection section facing the second body 22 with the opening of the mask body 2 as the boundary; in order to ensure that the side zipper 3 can close the side area E without interfering with the gap 31, the connecting section is configured to be connected to the second body 22 and extend to the position of the main zipper 5 along the outer contour of the gap B; the separation section is configured to be separated from the first body 21, and directly cross the gap B to extend to the position of the main zipper 5, thereby forming a hollow state at the position of the gap B; this design allows the separation section to complete the locking with the connecting section while bypassing the gap B, which not only ensures that the opening side area E is completely closed, avoids the loosening of the mask opening, but also avoids the interference of the entire avoidance section 31 with the gap B.

[0049] Further, if Figure 1 As shown, the side zipper 3 includes an avoidance section 31 extending toward the notch B. After bypassing the notch B, the avoidance section 31 continues to extend to the position of the main zipper 5, and is arranged alternately with the main zipper 5 at the opening of the cover body 2; after bypassing the notch B, the avoidance section 31 can enable the side zipper 3 to completely close the opening side area E, avoiding leaving a closed dead corner in the opening side area E; and the staggered arrangement design of the main zipper 5 and the avoidance section 31 can enable the avoidance section 31 to have a structural basis for being blocked by the main zipper 5.

[0050] Further, if Figure 2As shown, the avoidance section 31 in the side zipper 3 stops extending and intersects with the front zipper 5 after reaching the position of the front zipper 5, thereby forming a terminal end on the side zipper 3. When the front zipper 5 closes the middle area D by locking itself, only a lock head 6 of the front zipper 5 is exposed, and the side zipper 3 and the lock head 6 at the terminal end are blocked inside the cover body 2. This design simplifies the appearance and structure of the cover opening, which not only ensures the aesthetics of the cover opening, but also avoids the problem of the cover opening loosening or falling off caused by the lock head 6 being scratched or hooked with the outside world.

[0051] Further, if Figure 2 , Figure 7 As shown, the shielding effect of the front zipper 5 on the avoidance section 31 and the lock head 6 connected to the avoidance section 31 is determined by the different positional relationships between the front zipper 5 and the side zipper 3 at the opening of the cover body 2, wherein the connection position of the front zipper 5 at the opening of the cover body 2 is closer to the outside, and the connection section in the avoidance section 31 is connected to the second cover body 22, and extends along the outer contour of the notch B to the inside of the front zipper 5 after extending to the front zipper 5; so that the terminal position of the avoidance section 31 is enclosed in the arched range formed by the cover body 2 and the front zipper 5, so when the front zipper 5 closes the middle area D by itself, the front zipper 5 is pressed over the side zipper 3 and the lock head 6 at the terminal end position, so that when the front zipper 5 closes the middle area D, it forms a shielding effect on the side zipper 3 and the lock head 6 at the terminal end.

[0052] Furthermore, a receiving sleeve s is provided at the thickness position of the cover body 2, and the receiving sleeve s is located at the side of the opening start end; the pull tab 4 is located close to the opening start end, which is convenient for finding the pull tab 4; the placement opening of the receiving sleeve s and the opening start end can be opposite or opposite to each other; Figure 8 As shown, when the placement opening of the accommodating sleeve s is opposite to the starting end of the opening, after the opening of the covering sleeve body 2 is closed, the pull tab 4 can be removed by the lock head 6 and placed inside the accommodating sleeve s; so that the accommodating sleeve s can form a storage function for the pull tab 4, which is convenient for taking and storing the pull tab 4.

[0053] Furthermore, when the placement opening of the accommodating sleeve s is opposite to the starting end of the opening, the accommodating sleeve s is still at the side position of the starting end of the opening. After the opening of the covering sleeve body 2 is closed, since the placement opening of the accommodating sleeve s is opposite to the starting end of the opening, the pull tab 4 and the lock head 6 are both received in the accommodating sleeve s; such a design can also form the same storage effect for the lock head 6 and the pull tab 4.

[0054] A seat is further provided, which includes a new type of cover, which is wrapped around a chair back 1 or a chair seat; the lock 6 is connected to the pull tab 4 and then pulled to close the cover opening on the chair back 1 or the chair seat; the seat includes the new type of cover and the chair back 1, when the cover is wrapped around the chair back 1, a hole A corresponding to the position of the notch B is provided at the thickness position of the chair back 1; a back support rod 8 is inserted and fixed in the hole A; when the cover is wrapped around the chair seat; the cover becomes a seat cover 7 of the chair seat, the bottom surface of the seat cover 7 is open, and a seat zipper 71 is connected to the opening of the seat cover 7; the seat zipper 71 is also connected to a lock 6 that can close the zipper itself, and the lock 6 is connected to the pull tab 4 and then pulled to close the seat cover 7 opening; through the pull tab 4, the pull tab on the seat cover of the seat is no longer exposed to the outside, thereby improving the aesthetics of the seat, and when the seat is mass-produced, the design of the pull tab 4 can also reduce the production cost and improve the economy of the seat.

[0055] Furthermore, in order to fix the chair back 1, a back support rod 8 is inserted and fixed at the socket A. When the separation section of the avoidance section 31 is locked, although it is closed with the connecting section of the avoidance section 31, the separation section may still be turned outward. Once the avoidance section 31 of the separation section is turned outward, it will not only affect the appearance of the chair back 1, but also easily get hooked with external debris and damage the side zipper 3 or the cover body 2. After the side zipper 3 closes the side area E of the opening of the cover body 2, the separation section in the hollow state in the avoidance section 31 is locked as a whole with the connecting section; and is clamped between the back support rod 8 and the cover body 2 without turning outward; the clamped separation section remains fixed after the cover is closed, and will not be turned out and exposed under the traction of external force, thereby avoiding the edge of the zipper strip from getting hooked or scratched with the outside world due to turning outward.

[0056] Further, if Figure 5-6As shown, when the new cover is wrapped on the seat, the cover becomes the seat cover 7 of the seat, and the seat cover 7 has an opening, and a seat zipper 71 is connected to the opening, and the seat zipper 71 has a starting end and an ending end; the seat zipper 71 is also connected to a lock head 6 of the closable zipper itself, and when the lock head 6 slides to the ending end of the seat zipper 71 under the pull of the pull tab 4, the pull tab 4 and the lock head 6 are both received in the accommodating sleeve s; after the closing process of the cover opening is completed, the pull tab 4 is first removed from the lock head 6 on the main zipper 5, and then connected to the lock head 6 of the locking zipper 71 itself, and the pull tab is pulled to close the zipper. 4 drives the lock head 6 to slide from the starting end of the locking zipper 71 to the ending end to close the seat cover 7; considering the storage problem of the pull tab 4, the seat cover 7 is provided with a accommodating sleeve s at the ending end of the seat zipper 71. When the lock head 6 slides to the ending end of the seat zipper 71 under the pull of the pull tab 4 to close the opening of the seat cover 7, the pull tab 4 and the lock head 6 are both received in the accommodating sleeve s; the accommodating sleeve provided on the seat cover 7 can form a storage function for the lock head 6 and the pull tab 4, and can also separate the lock head 6 of the locking zipper 71 on the seat cover 7 from the outside, so as to ensure the fixing covering effect of the locking zipper 71 at the opening of the seat cover 7.

[0057] Further, if Figure 3b , Figure 6 As shown, in order to avoid slipping of the hand when grasping the pull tab 4, a through hole 44 is provided at the tail of the pull tab 4. When the pull tab 4 is received in the accommodating sleeve s, the through hole 44 is exposed outside the accommodating sleeve s. When the pull tab 4 needs to be connected with the corresponding lock head 6 to close the seat cover 7 or the cover body 2, the pull tab 4 can be pulled out of the accommodating sleeve s by grasping the outer edge of the through hole 44 at the tail of the pull tab 4.

[0058] Furthermore, while ensuring the stability of the covering, the cover allows the front opening and closing unit 5 to separate itself to open the middle area D, and then allows the side opening and closing unit 3 to separate itself to open the side area E, thereby completely opening the opening of the cover body 2 so that the cover can be removed from the chair back 1; the opening and closing unit can open the opening of the cover so that the cover can be quickly removed from the chair back 1, thereby facilitating replacement and cleaning.

[0059] Furthermore, in order to ensure that the cover is easy to remove, wash and replace, it is usually necessary to disassemble the cover. The process of disassembling the cover is roughly the opposite of the process of closing the cover, that is, first take the pull tab 4 out of the containing cover s, connect it to the lock 6 on the front zipper 5 and pull the pull tab 4, so that the front zipper 5 opens the middle area D, and at the same time the terminal end and the lock 6 of the side zipper 3 are exposed, then remove the pull tab 4 from the lock 6 on the front zipper 5 and connect it to the lock 6 on the side zipper 3 and pull the pull tab 4, so that the side zipper 3 opens the side area E, so that the cover body 2 can be removed from the chair back 1.

[0060] Example 2: Figure 3aAs shown, the difference between this embodiment and embodiment 1 is that the rotating part 41 and the rotating shaft 43 are not provided in this embodiment, so that the pull tab 4 and the lock head 6 are connected or disassembled only through the hanging gap 46, so that the disassembly and assembly process of the pull tab 4 and the lock head 6 is simplified to a simple hooking and separation process, and the matching process of the rotating part 41 and the limiting part 45 is omitted, so that the pull tab 4 and the lock head 6 are matched more quickly and efficiently.

[0061] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
