Technical Field

[0001] This utility model relates to the field of double seat technology, and in particular to a double seat with a rotatable and foldable center armrest. Background Technology

[0002] In modern life and various public and private spaces, seating is an indispensable piece of furniture or facility. As people's demands for space utilization efficiency and ease of use continue to increase, the traditional design of two-seater chairs is gradually revealing some limitations. In some spaces with limited space, such as small meeting rooms, compact office rest areas, and apartment living rooms, the fixed center armrest of traditional two-seater chairs often occupies a certain amount of space, hindering people's free movement and activities. This inconvenience is even more prominent when frequent adjustments to the seating arrangement are needed or when multiple people share a limited space. Moreover, in some special scenarios, such as when it is necessary to move or temporarily adjust the position of the chair, the fixed center armrest may collide with surrounding objects, causing damage or hindering operation.

[0003] Currently, most existing double chairs have fixed armrest positions after installation, lacking spacious, comfortable, and foldable shared armrests, which affects communication, interaction, or the placement of items. Therefore, we propose a double chair with a rotating and foldable central armrest. Utility Model Content

[0004] The purpose of this utility model is to provide a double seat with a rotatable and foldable armrest, in order to solve the problem that the armrest position of most existing double seats is fixed after installation, and there is no spacious, comfortable and foldable shared armrest, which affects communication and interaction or the placement of items.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double seat with a rotatable and foldable center armrest, comprising two sets of side armrests, a seat fixedly installed between the two sets of side armrests, side guard plates fixedly installed on the outer sides of both sets of side armrests, a rear plate fixedly installed between the two sets of side guard plates, a center armrest and a fixed seat installed in the middle of the rear plate, a rotation stabilizing device provided on the center armrest, the rotation stabilizing device comprising a mounting groove, a fixed shaft fixedly installed on the rear side of the inner wall of the mounting groove, a stabilizing column fixedly installed on the circumferential surface of the fixed shaft, and a hinge fixedly installed between the center armrest and the fixed seat.

[0006] As a preferred embodiment, storage boxes are fixedly installed on the outer surfaces of both sets of side panels, and multiple chair backs are fixedly installed on the side surface of the rear panel near the seat and on both sides of the middle armrest. Leg support devices are provided on both sides of the bottom of the seat.

[0007] As a preferred embodiment, the mounting groove is provided in two sets and is opened on both sides of the surface of the middle handrail. The stabilizing column is set in the mounting groove, and a pull ring is fixedly installed at the middle of the circumferential surface of the two sets of stabilizing columns.

[0008] As a preferred embodiment, the surface of the chair seat is provided with two sets of positioning holes that are adapted to the two sets of stabilizing posts.

[0009] As a preferred embodiment, the leg support device includes two sets of sliders, with a support plate slidably connected inside the two sets of sliders, and a foot pad fixedly installed on the surface of the support plate.

[0010] As a preferred embodiment, baffles are fixedly installed on the front bottom of the two sets of sliders, a limiting plate is fixedly installed on the rear bottom of the support plate, the two sets of sliders are fixedly installed on the bottom of the seat, the limiting plate does not contact the sliders, and a pull block is fixedly installed on the front surface of the support plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting up a rotating stabilizing device, when the middle handrail needs to be lowered, first pull the pull ring to make the stabilizing column rotate on the fixed shaft surface until it is perpendicular to the middle handrail. Then, use the hinge to rotate the middle handrail. At this time, the stabilizing column will be inserted into the positioning hole to stabilize the middle handrail, making it convenient for two people to use. Conversely, if you want to fold and store it, lift the middle handrail up, rotate the stabilizing column and store it into the mounting slot.

[0013] 2. By setting up a leg support device, when the user sits on the chair, pulling the lever will slowly pull the support plate out of the slider until the limiting plate and the baffle on the back of the support plate abut against each other. This is the maximum extension length. In this state, the user can lift their legs and place them on the foot pad of the support plate, so that the legs can get a full rest and relaxation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see the appendix Figure 1 - Appendix Figure 5 A double seat with a rotatable and foldable center armrest includes two sets of side armrests 1, a seat 2 fixedly installed between the two sets of side armrests 1, side guard plates 3 fixedly installed on the outer sides of each set of side armrests 1, a back panel 4 fixedly installed between the two sets of side guard plates 3, a center armrest 5 and a fixed seat installed in the middle of the back panel 4, a rotation stabilizing device 6 provided on the center armrest 5, the rotation stabilizing device 6 including a mounting groove 602, a fixed shaft 605 fixedly installed on the rear side of the inner wall of the mounting groove 602, and a stabilizing column 603 fixedly installed on the circumferential surface of the fixed shaft 605, and a stabilizing column 603 fixedly installed between the center armrest 5 and the fixed seat. A hinge 606 is fixedly installed. Storage boxes 9 are fixedly installed on the outer surfaces of both sets of side panels 3. Multiple backrests 8 are fixedly installed on the side surface of the back panel 4 near the seat 2 and on both sides of the middle armrest 5. Leg support devices 7 are provided on both sides of the bottom of the seat 2. Two sets of mounting grooves 602 are provided and are opened on both sides of the surface of the middle armrest 5. Stabilizing posts 603 are set in the mounting grooves 602. Pull rings 604 are fixedly installed in the middle of the circumferential surface of the two sets of stabilizing posts 603. Two sets of positioning holes 601 that are compatible with the two sets of stabilizing posts 603 are opened on the surface of the seat 2.

[0023] The middle armrest 5 is generally where users place their hands or objects, and it usually bears a large weight. Therefore, the combination of the stabilizing column 603 and the positioning hole 601 is used to support the middle armrest 5 to prevent it from becoming unstable after long-term use.

[0024] Specifically, when the middle armrest 5 needs to be lowered, first, pull the pull ring 604, and the stabilizing post 603 rotates on the surface of the fixed shaft 605 so that its rotation is perpendicular to the middle armrest 5. Then, under the action of the hinge 606, the middle armrest 5 rotates, and the stabilizing post 603 is inserted into the positioning hole 601, so that the middle armrest 5 is in a stable state, which is convenient for two users to use together. Conversely, lift the middle armrest 5 up and rotate the stabilizing post 603 to store it in the mounting slot 602, which completes the folding and storage. Example 2

[0025] Please see the appendix Figure 1 - Appendix Figure 2 Appendix Figure 4 and appendix Figure 6 Furthermore, based on Embodiment 1, the leg support device 7 includes two sets of sliders 701, with a support plate 702 slidably connected inside the two sets of sliders 701. A foot pad 704 is fixedly installed on the surface of the support plate 702. A baffle 706 is fixedly installed on the bottom front side of the two sets of sliders 701. A limiting plate 705 is fixedly installed on the bottom rear side of the support plate 702. The two sets of sliders 701 are fixedly installed on the bottom of the seat 2. The limiting plate 705 does not contact the sliders 701. A pull block 703 is fixedly installed on the front surface of the support plate 702.

[0026] The bottom of the seat 2 is horizontal, and the support plate 702 installed inside the slider 701 is also horizontal when pulled out. It does not automatically retract during use. The foot pads 704 provide comfort for the user.

[0027] Specifically, when the user sits on the seat 2, pulling the pull block 703 will pull the support plate 702 out of the slider 701 until the limiting plate 705 on the back of the support plate 702 abuts against the baffle 706. At this time, the maximum extension length is reached, and the user can lift his / her legs and place them on the foot pad 704 of the support plate 702 to allow his / her legs to rest.

[0028] Working principle of this utility model: This utility model is a double seat with a rotatable and foldable middle armrest. When the middle armrest 5 needs to be lowered, first pull the pull ring 604 to make the stabilizing column 603 rotate on the surface of the fixed shaft 605 until it is perpendicular to the middle armrest 5. Then, the hinge 606 rotates the middle armrest 5. At this time, the stabilizing column 603 is inserted into the positioning hole 601 to stabilize the middle armrest 5, making it convenient for two people to use. After the user sits on the seat 2, pull the pull block 703 to slowly pull the support plate 702 out of the slider 701 until the support plate is fully extended. The limiting plate 705 and the baffle 706 on the rear side of 702 abut against each other, which is the maximum pull-out length. In this state, the user can lift his / her legs and place them on the foot pads 704 of the support plate 702, so that the legs can get a full rest and relaxation. The user can put items in the storage box 9. Conversely, if the middle armrest 5 is to be folded and stored, lift the middle armrest 5 upwards, rotate the stabilizing column 603 and put it into the mounting slot 602, push the support plate 702 and put it into the slider 701. At this point, the whole process is complete.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
