Description

Technical Field

[0001] This utility model relates to the field of furniture design technology, and in particular to a foldable and retractable booth seat. Background Technology

[0002] Booth seating is widely used in existing furniture designs because it provides comfortable seating and increases space utilization. However, traditional booth seating has fixed cushions, making it difficult to adjust the size of the cushions according to actual usage needs.

[0003] Some booth seats have a folding function, but the support frame is usually locked by a pin or buckle. When folding the booth seat, the limit on the support frame needs to be released manually. The folding of the seat cushion and the unfolding of the support frame need to be done in steps, which is time-consuming and has limited folding efficiency. Utility Model Content

[0004] To address the drawback of the time-consuming folding process in existing card holders, this invention provides a foldable card holder.

[0005] The technical implementation scheme of this utility model is as follows: a foldable storage card holder includes a base, a backrest cushion connected to the back of the base, a fixed seat cushion connected to the top of the base, a movable seat cushion above the fixed seat cushion, the fixed seat cushion and the movable seat cushion having two states: folded and unfolded, a sliding support frame provided on the top of the base, the support frame being used to support the unfolded movable seat cushion, a pair of fixed plates connected to both sides of the base, a pair of connecting rods slidably connected between each pair of fixed plates, a wedge block for limiting the support frame connected between each pair of connecting rods, and an elastic element connected between the wedge block and the connecting rod.

[0006] More preferably, the foldable storage holder also includes guide rods and compression plates. A pair of guide rods are connected to both sides of the base, and a compression plate that slides up and down between each pair of guide rods is provided. The compression plate is used to compress the connecting rod, and a compression spring is connected between the guide rod and the compression plate.

[0007] More preferably, the extrusion plate is divided into an upper vertical section, a lower vertical section, and an inclined section.

[0008] More preferably, a pair of connecting rods are connected to both sides of the fixed seat cushion and the movable seat cushion. Hinges are installed between the two pairs of connecting rods on the left and the two pairs of connecting rods on the right. Each hinge includes a pair of blades and a pivot pin, with the blades connected to the connecting rods.

[0009] More preferably, the foldable storage seat also includes a contact plate, and the blades on the front side of the hinge are all connected to a contact plate for pushing the pressing plate down.

[0010] More preferably, the support frame has straight grooves on both sides, and the base has limit blocks located in the straight grooves on both sides.

[0011] Compared with the prior art, the present invention has the following advantages: the fixed cushion and the movable cushion have unfolded and folded states, making them flexible in use; the support frame supports the movable cushion when it is unfolded; the wedge block restricts the position of the support frame; the wedge block can automatically release its limiting effect on the support frame while the movable cushion is folded; and the wedge block can automatically restore its limiting effect on the support frame while the movable cushion is unfolded. This results in high synchronization, reduced folding time, and improved folding efficiency. Attached Figure Description

Detailed Implementation

[0019] A foldable, retractable booth seating arrangement, reference. Figures 1-6The system includes a base 1, a backrest cushion 2, a fixed seat cushion 3, a movable seat cushion 4, a support frame 5, a fixing plate 6, a connecting rod 7, and a wedge block 8. The backrest cushion 2 is fixedly connected to the top rear side of the base 1, and the fixed seat cushion 3 is fixedly connected to the top of the base 1. The movable seat cushion 4 is located above the fixed seat cushion 3. A pair of connecting rods 41 are fixedly connected to the left and right sides of both the fixed seat cushion 3 and the movable seat cushion 4. Hinges are installed between the two pairs of connecting rods 41 on the left and the two pairs of connecting rods 41 on the right. Each hinge includes a pair of leaf blades 42 and a pin 43. The pin 43 is rotatably connected to the pair of leaf blades 42, and the leaf blades 42 are connected to the ends of the connecting rods 41. The fixed seat cushion 3 and the movable seat cushion 4 can be folded or unfolded. In the base 1, a support frame 5 that slides back and forth is provided on the top. The fixed seat 3 is located above the support frame 5. The bottom of the support frame 5 has movable wheels to push the support frame 5. The support frame 5 is used to support the movable seat 4 after it is unfolded. A pair of fixed plates 6 are fixedly connected to the upper part of the left and right sides of the base 1. A pair of connecting rods 7 are slidably connected between each pair of fixed plates 6. A wedge block 8 for limiting the support frame 5 is fixedly connected between the front ends of each pair of connecting rods 7. The wedge block 8 has an inclined surface on the rear side to facilitate the pulling out of the support frame 5. An elastic element is fixedly connected between the wedge block 8 and the connecting rod 7. The elastic element is a return spring. The wedge block 8 is blocked on the rear side of the support frame 5.

[0020] refer to Figure 2 , Figure 3 and Figure 5 The foldable storage card holder also includes guide rods 71 ​​and pressing plates 72. A pair of guide rods 71 ​​are fixedly connected to the lower part of the left and right sides of the base 1. Each pair of guide rods 71 ​​is provided with a pressing plate 72 that slides up and down. The pressing plate 72 is used to press the connecting rod 7. A compression spring is fixedly connected between the guide rods 71 ​​and the pressing plate 72. The pressing plate 72 is divided into an upper vertical section, a lower vertical section and an inclined section 73. When the pressing plate 72 descends, the inclined section 73 presses the connecting rod 7 to slide, so that the wedge block 8 leaves the rear side of the support frame 5.

[0021] refer to Figure 2 , Figure 3 and Figure 6 The foldable storage seat also includes a contact plate 74. The blades 42 on the front side of the hinge are all connected to the contact plate 74 for pushing the pressing plate 72 down. When the fixed seat 3 and the movable seat 4 are in the folded state, the hinge is closed, and the contact plate 74 will press down the pressing plate 72.

[0022] refer to Figure 2 The support frame 5 has straight grooves 50 on the upper part of both the left and right sides, and the base 1 has limit blocks 51 located in the straight grooves 50 on the upper part of both the left and right sides.

[0023] refer to Figure 1 and Figure 2 The base 1 has protective shells 9 fixedly connected to both the left and right sides, and the protective shells 9 serve a protective function.

[0024] Initially, the fixed seat cushion 3 and the movable seat cushion 4 are... Figure 1 In the unfolded state shown, the support frame 5 is in the pulled-out state, and the support frame 5 supports the movable seat cushion 4. The wedge block 8 is placed behind the support frame 5, thereby restricting the position of the support frame 5 through the wedge block 8 and ensuring the stability of the movable seat cushion 4 during use.

[0025] When the storage seat needs to be folded, the movable seat 4 is manually lifted and folded above the fixed seat 3, so that the two leaflets 42 of the hinge close, and the movable seat 4 and the fixed seat 3 become... Figure 2 In the folded state shown, the hinge blade 42 drives the contact plate 74 to rotate around the shaft pin 43. The contact plate 74 presses down on the pressing plate 72, and the pressing plate 72 slides down along the guide rod 71. The compression spring is compressed, and the downward-moving pressing plate 72 presses the connecting rod 7 through the inclined part 73, causing the connecting rod 7 to slide away from the base 1. The upper vertical section of the pressing plate 72 abuts against the connecting rod 7, driving the wedge block 8 away from the rear side of the support frame 5. The reset spring is compressed, and the wedge block 8 no longer limits the support frame 5. At this time, the support frame 5 can be pushed to move backward, thereby folding up the support frame 5.

[0026] When it is necessary to unfold the fixed cushion 3 and the movable cushion 4 again, simply pull out the support frame 5. The maximum pulling distance of the support frame 5 is limited by the limiting block 51 to ensure the accurate positioning of the support frame 5. Then, lift the movable cushion 4, which will cause the two blades 42 of the hinge to open. The contact plate 74 will separate from the pressing plate 72, and the compression spring will return to its original position. This will allow the pressing plate 72 to slide upwards along the guide rod 71 and return to its original position. The pressing plate 72 will no longer press the connecting rod 7. The return spring will return to its original position, allowing the connecting rod 7 and the wedge block 8 to move towards the base 1 and return to their original position. The wedge block 8 can then limit the support frame 5 again. In this way, the fixed cushion 3 and the movable cushion 4 have two states: unfolded and folded. The usage is flexible. When folding the movable cushion 4, the limiting effect of the wedge block 8 on the support frame 5 can be automatically released. When unfolding the movable cushion 4, the limiting effect of the wedge block 8 on the support frame 5 can be automatically restored. The synchronization is high, reducing the folding time and improving the folding efficiency.
