DETAILED DESCRIPTION
[0026] The utility model provides a cloth cover rope-bound folding chair, comprising a folding chair frame and a cloth cover 1 arranged on the folding chair frame. The folding chair frame comprises a seat 2, front chair legs 3, rear chair legs 4, armrests 5 and a backrest 6. The folding chair frame of the utility model has a plurality of movable connection positions, and the movable connection can be realized by selecting corresponding connecting pieces, or by setting movable pins for movable connection, and the movable connection method can be selected according to the actual installation position.
[0027] The front end of the seat 2 and the middle position of the front leg 3 are movably connected, and can be connected by a movable pin; the rear end of the seat 2 is movably connected to the lower end of the backrest 6, which can be assisted by a U-shaped connecting piece, and a corresponding movable pin is arranged on the connecting piece to movably connect the rear end of the seat 2 and the lower end of the backrest 6, so that horizontal folding can be achieved after the connection.
[0028] The upper ends of the front chair legs 3 and the rear chair legs 4 are movably connected as one body through the chair leg connector 7, and a movable connector is provided between the middle of the rear chair leg and the backrest. The inside of the armrest is hollow, and a plurality of clamping positions are provided on the two side walls inside. Below the clamping positions are a slide groove and an anti-slip plate in sequence, and the slide groove is a channel formed by the horizontal space between the clamping position and the anti-slip plate; clamping heads are provided on both sides of the chair leg connector, and the clamping heads are locked in position after being inserted into the clamping positions. When the clamping heads 72 exit the clamping positions, they are confined in the space between the slide groove and the anti-slip plate 53; the clamping heads enter the clamping positions when the folding chair is unfolded, and the clamping heads exit the clamping positions when the armrest is pulled upward.
[0029] A pin hole is provided on the chair leg connecting member 7, and the upper ends of the front chair leg 3 and the rear chair leg 4 are fixed to the chair leg connecting member 7 by a movable pin 71. After the two are fixed, they can move around the movable pin as the center, so that the front chair leg 3 and the rear chair leg 4 can move relative to each other.
[0030] A movable connecting piece 8 is arranged between the middle part of the rear chair leg 4 and the backrest 6. The upper end of the movable connecting piece can be a pin shaft inserted into the lower end of the backrest 6 to realize a movable connection with the backrest 6. The lower end of the movable connecting piece can be a U-shaped connecting piece. After the middle part of the rear chair leg 4 is placed inside the U-shaped connecting piece, a movable pin is used to connect and fix it.
[0031] The inside of the armrest 5 is hollow, and its shape is similar to a strip groove. The hollow space is convenient for the chair leg connector 7 to move inside it. A plurality of latches 52 are arranged on the two side walls inside the armrest 5. Below the latches 52 are the slide grooves 51 and the anti-slip plates. The slide grooves 51 are channels formed by the horizontal space between the latches 52 and the anti-slip plates 53. The latches 52 are not arranged horizontally. The slide grooves 51 and the anti-slip plates are arranged horizontally. The latches 52 can be a vertically arranged groove-like structure, or a tilted groove-like structure with a small arc.
[0032] A clamping head is provided on both sides of the chair leg connecting piece. The clamping head is locked in position after being inserted into the clamping position 52. When the clamping head withdraws from the clamping position 52, it is confined in the space between the slide groove 51 and the anti-slip plate; the clamping head enters the clamping position 52 when the folding chair is unfolded, and withdraws from the clamping position 52 when the armrest is pulled upward.
[0033] The chair leg connector has a clamping head on both sides, that is, the upper end of the chair leg connector has two clamping heads on the left and right, each group of clamping positions 52 includes two clamping positions 52, and the two clamping positions 52 of each group are respectively arranged on the left and right inner walls inside the armrest. When the clamping head is inserted into the clamping position 52, the two clamping heads on the left and right enter the corresponding positions of the clamping positions 52, so the setting positions of the two clamping positions 52 of each group of clamping positions 52 are corresponding. The chair leg connector 7 has multiple groups of clamping positions 52, which are generally designed to be 4 to 6 groups of clamping positions 52, and the clamping positions 52 are distributed along the horizontal direction of the armrest 5.
[0034] When the clamp is inserted into the clamping position 52, there is a gap between the clamp and the clamp 52, and the two are not fixed. After the clamp is inserted into the clamp 52, it can only move up and down. Due to the restriction of the clamp 52, the clamp cannot move left and right. Since the chair itself is under the action of gravity, no matter whether there is someone sitting on the chair, the armrest will be subject to gravity, so that the armrest will be naturally set above the chair leg connector. Due to the limiting effect of the anti-drop plate, the chair leg connector will not fall off, so the chair leg connector can play a load-bearing role.
[0035] There is a gap between the positions 52 and 52, and the clamping head can only move in the slide groove 51 at the gap. When people unfold the folding chair, the clamping head will randomly get stuck in a position 52. If it cannot be directly stuck, people can also try repeatedly by adjusting the position appropriately, so that the clamping head enters the position 52; therefore, the combination of the clamping head and the position 52 may require repeated attempts to adjust the position, but this adjustment is also relatively easy, because the gap size between the two positions 52 is also small. When the sitting angle needs to be adjusted, people can pull the armrest upwards. At this time, since there is someone on the seat 2 and it has a certain weight, the front and rear legs will be subject to a certain gravity. The leg connector 7 is connected to the front leg 3 and the rear leg 4, so it is also subject to downward gravity. At this time, the armrest is pulled upwards, and the armrest position 52 and the clamping head 72 are not fixedly connected, but a clamping structure, and the clamping head is subjected to a downward force to keep it still, so at this time only the armrest moves upwards, and the clamping head does not move upwards with it. When the handrail moves upward, the clamping position 52 also moves upward, so that the clamping head withdraws from the clamping position 52, and then the clamping head reaches the position of the chute 51; at this time, people can push the handrail forward and backward. During the movement of the handrail forward and backward, other clamping positions 52 will reach the top of the clamping head. At this time, people can press down the handrail to make the new clamping position 52 cooperate with the clamping head. In this process, the clamping head is stationary, and it is the handrail and the clamping position 52 that are moving. If the new clamping position 52 cannot cooperate with the clamping head when the handrail is pressed down, it is possible that it just moves to the position between the two clamping positions 52. At this time, people can adjust the position appropriately and continue to adjust so that the clamping position 52 just moves to the top of the clamping head. During the movement, due to the limitation of the anti-slip plate, the clamping head can never fall off from the chute 51. At the same time, in order to be able to load the clamping head into the chute 51 or the inside of the handrail, openings can be opened at both ends of the handrail to allow the clamping head to enter the inside of the handrail from the openings, and then the two ports can be closed.
[0036] The rear part of the armrest 5 is movably connected to the backrest 6. The front end of the cloth cover 1 is provided with a lower bag 9 nested in the front end of the seat 2, and the other end of the cloth cover 1 is provided with an upper bag 10 sleeved on the backrest 6; both sides of the cloth cover 1 are provided with perforations 11, and the binding rope 12 passes through the perforations 11 and is connected to the seat 2 and the backrest 6, and is supported under the cloth cover 1 to bear the weight. There are 10 to 18 perforations 11 designed on both sides of the cloth cover 1, and the binding rope 12 passes through the holes 11 back and forth on both sides of the cloth cover 1 in turn, and is simultaneously wrapped around the metal tubes of the seat 2 and the backrest 6, so that the binding rope 12 can also be connected to the seat 2 and the backrest 6 to achieve load-bearing.
[0037] In order to provide better support at the rear when switching to a recliner, a lying support frame can be provided at the rear side of the backrest 6, and the lying support frame is movably connected to the backrest 6 through an adapter 14. When switching to a recliner, the lying support frame 13 is rotated 90° and placed vertically to achieve support.
[0038] In a preferred embodiment of the utility model, a crossbar 15 is provided on the front leg 3, and both ends of the crossbar have U-shaped forks 16, which are embedded in the tube wall of the front leg 3 and then fixed by pins. The crossbar can act as a reinforcing rib, which can improve the load-bearing capacity of the front leg 3.
[0039] In the preferred embodiment of the utility model, rivets are arranged between the lower cover 9 and the seat 2 for reinforcement, so as to prevent the cloth cover 1 from slipping.
[0040] In a preferred embodiment of the utility model, a backpack 17 is arranged at the rear side of the backrest 6, and the backpack has a heat insulation layer inside; the backpack is equipped with a zipper; and a headrest is arranged at the front side of the backrest 6. The heat insulation layer can be formed by combining existing pearl cotton and heat insulation film, and the heat insulation layer can prevent the refrigerated and frozen items placed inside from heating up quickly.
[0041] In a preferred embodiment of the present invention, a storage bag is provided on one side of the armrest 5, and a notch 18 is provided on the other side. A hanging ear 19 is provided in the notch, and the hanging ear can hang lighter objects such as pockets; an anti-slip pad is also provided on the upper end surface of the armrest 5.
[0042] In the preferred embodiment of the utility model, two straps are arranged on the cloth cover 1 at the lower end surface of the seat 2, the front end of the straps is connected to the cloth cover 1 at the lower side of the front end of the seat 2, and the rear end of the straps is connected to the cloth cover 1 at the lower side of the rear end of the seat 2. The design of the straps is similar to the straps 20 of a schoolbag. The straps are designed on the lower end surface of the seat 2, which is also conducive to the straps not being exposed to the side when the folding chair is used, which is easy to trip passers-by.
[0043] In the preferred embodiment of the utility model, a male end strap 21 is provided on the cloth cover 1 at the lower side of the front end of the seat 2, and a female end strap 22 is provided at the rear side of the upper end of the backrest 6. The male end strap and the female end strap are connected after the folding chair frame is folded.
