Description

Technical Field

[0001] This utility model relates to the field of plastic chair technology, specifically a portable lightweight plastic injection molded chair. Background Technology

[0002] A plastic injection-molded chair is a chair manufactured using the plastic injection molding process. Injection molding is a common method of processing plastic materials. It involves heating the plastic material to a molten state, then using an injection molding machine to inject it into a mold cavity of a specific shape. After cooling, the molded product is formed, thus creating a plastic product with specific shape and performance requirements.

[0003] Many existing chairs suffer from the following drawbacks: either the armrest design is fixed and monotonous, taking up space and making movement in confined spaces difficult due to obstruction, thus causing inconvenience when armrests are not needed; or there are no armrests at all, failing to meet the needs of those who require them, making it difficult for some elderly or other disabled people to get up. Furthermore, some non-one-piece molded chairs have loose connections between components, complex structures, and are not lightweight enough. To address the shortcomings of existing technologies, this utility model provides a portable, lightweight plastic injection-molded chair to solve the above problems. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This application provides a portable, lightweight plastic injection-molded chair, solving the problems of existing chair armrest designs that are either always present, taking up space and making it very inconvenient for people to move around in compact spaces, as the armrests can obstruct movement, thus causing inconvenience in scenarios where armrests are not needed; or having no armrests at all, failing to meet the needs of people in need, making it difficult for some elderly or other disabled people to get up. Furthermore, some non-one-piece molded chairs have loose connections between components, complex structures, and are not lightweight enough.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] Example 1: This utility model embodiment discloses a portable lightweight plastic injection-molded chair, according to the attached... Figure 1-5 As shown, it includes a seat panel 1, seat legs 2, backrest panel 3, reinforcing ribs 4, armrests 7, storage sleeves 5, limiting sleeves 6, and multiple limiting mechanisms 8.

[0034] The seat panel 1 serves as the main load-bearing structure, providing a support platform for the user's sitting posture. The seat legs 2 are connected to the bottom of the seat panel 1, supporting the overall weight and ensuring the chair remains stable on the ground. The backrest 3 is located at the top of the seat panel 1, providing support for the user's back and reducing fatigue from prolonged sitting. Reinforcing ribs 4 are located between the seat panel 1 and the seat legs 2, strengthening the connection between them and increasing its load-bearing capacity.

[0035] The armrest 7 has a movable locking function, allowing for flexible switching between states. The storage sleeve 5 is located at the bottom of the seat panel 1. When the armrest 7 is locked into it, it is in a stored state, meaning the chair has no armrests. This is convenient for use in scenarios where armrests are not needed, such as next to a compact dining table, preventing armrests from taking up too much space. The limiting sleeve 6 is located on the backrest panel 3. When the armrest 7 is locked into the limiting sleeve 6, it becomes an armrest, providing arm support for the user, suitable for scenarios where armrests are needed to assist in getting up or leaning against something.

[0036] The limiting mechanism 8 includes multiple sets of sleeves 81, pins 82, pull rods 83, and springs 84. Sleeves 81 are fixed to the receiving sleeve 5 and the limiting sleeve 6 via mounting plates 811. Pull rods 83 slide within sleeves 81 and are connected to pins 82. Springs 84 connect pull rods 83 and sleeves 81. Under normal conditions, springs 84 push pins 82 out, inserting them into the limiting hole 72 of the handrail 7 to achieve limiting. When unlocking is required, pull rods 83 are pulled, causing pins 82 to retract. Releasing pull rods 83 allows pins 82 to reset under the action of springs 84, awaiting the next limiting action.

[0037] To retract the handrail 7, hold the handrail 7, align it with the opening of the storage sleeve 5, and insert it while simultaneously pulling the lever 83. The lever 83 will cause the pin 82 to retract into the sleeve 81 and compress the spring 84. When the handrail 7 is engaged with the storage sleeve 5, release the lever 83. Under the action of the spring 84, the pin 82 will reset and insert into the limiting hole 72, indicating that the engagement is complete. To restore the handrail to its original state, first pull the lever 83 and pin 82 of the limiting mechanism 8 to overcome the elasticity of the spring 84 and pull the handrail 7 out of the storage sleeve 5. Then align it with the insertion hole of the limiting sleeve 6, and simultaneously pull the lever 83 and pin 82, insert them, and release the lever 83. Under the action of the spring 84, the pin 82 will insert into the limiting hole 72 on the handrail 7, completing the fixation.

[0038] Example 2: This utility model embodiment discloses a portable lightweight plastic injection-molded chair, according to the attached... Figure 1-5 As shown, it includes a seat panel 1, seat legs 2, backrest panel 3, reinforcing ribs 4, armrests 7, storage sleeves 5, limiting sleeves 6, and multiple limiting mechanisms 8.

[0039] Seat legs 2 are located at the bottom of seat plate 1;

[0040] Backrest panel 3 is located on top of seat panel 1;

[0041] The reinforcing rib 4 is located between the seat plate 1 and the seat leg 2;

[0042] The armrest 7 is attached to the seat panel 1.

[0043] The storage sleeve 5 is located at the bottom of the seat plate 1 and is used to store the armrest 7;

[0044] The limiting sleeve 6 is set on the backrest panel 3 and is used to engage the armrest bar 7;

[0045] Multiple sets of limiting mechanisms 8 are respectively installed on the storage sleeve 5 and the limiting sleeve 6 and are used to limit the handrail 7.

[0046] Each sleeve 81 is equipped with a mounting plate 811, and multiple sets of mounting plates 811 are fixedly connected to the receiving sleeve 5 and the limiting sleeve 6 respectively. The mounting plates 811 are fixed to the receiving sleeve 5 and the limiting sleeve 6 respectively by bolts, thereby making the installation of the sleeve 81 convenient.

[0047] The seat panel 1 has a slot 11, and the armrest 7 has a locking block 71, which is movably engaged in the slot 11. When the armrest 7 is inserted into or removed from the limiting sleeve 6, the locking block 71 will automatically align with the slot 11 and engage or disengage. The engagement of the locking block 71 with the slot 11 further enhances the connection stability between the armrest 7 and the seat panel 1, preventing the armrest 7 from shaking or shifting during use.

[0048] The bottom of the reinforcing rib 4 is provided with a reinforcing tube 41 for limiting the position of the armrest 7. When the armrest 7 is in the retracted state, it can provide additional limiting and reinforcement for the armrest 7 stored at the bottom of the seat board 1, preventing the armrest 7 from shaking or falling off due to bumps during the transportation and placement of the chair, and ensuring the stability of the retracted state.

[0049] The reinforcing rib 4, backrest panel 3, seat legs 2, and seat panel 1 are designed as a single piece. This single-piece design eliminates gaps between these components, ensuring structural continuity and significantly increasing overall strength. It can withstand greater weight and more complex stress conditions, extending the chair's lifespan. At the same time, it reduces quality issues caused by loose or detached parts, lowering maintenance difficulty and costs.
