Description

Technical Field

[0001] This utility model belongs to the field of chair technology and relates to a multifunctional dining chair. Background Technology

[0002] Dining chairs, as a type of seating specifically designed for dining, primarily function and are designed to complement dining tables perfectly. They are not merely standalone pieces of furniture, but rather essential elements closely connected to and reinforcing the dining table.

[0003] In most households, people don't buy high chairs if they don't have children. However, when guests bring children to dine at home, ordinary high chairs don't have armrests on the sides, making it easy for children to slip off. Therefore, it's essential to design a multifunctional high chair. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a multifunctional dining chair.

[0005] The purpose of this utility model can be achieved through the following technical solution: A multifunctional dining chair, including a frame, on which a backrest, a seat cushion, and chair legs are fixedly installed. The chair is characterized in that L-shaped bases are fixedly installed on both sides of the frame. One end of each L-shaped base is horizontally fixedly connected to a guide shaft, both ends of which are movably connected to support beams. The upper ends of the support beams are fixedly connected to a limiting armrest, and the lower ends of the support beams are fixedly connected to a crossbar. The crossbar has a threaded hole one, and the other end of the L-shaped base has a threaded hole two. Locking screws are installed in the threaded holes one and two.

[0006] A magnet is installed on the L-shaped base, and an iron plate that attracts the magnet is installed on the restraining handrail.

[0007] The L-shaped base also has multiple mounting holes at one end.

[0008] The locking screw is a hand-tightening component.

[0009] The support beam is provided with a guide groove that mates with the guide shaft.

[0010] Compared with existing technologies, this multi-functional dining chair has the following advantages:

[0011] In this invention, when guests bring children to dine at home, the armrests on both sides can be pulled out from the bottom of the dining chair, making them vertical and fixed. In this way, the armrests can prevent children from sliding off the sides of the dining chair. When not in use, the armrests can be stored at the bottom of the dining chair to meet different temporary use needs. Attached Figure Description

Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1-3 As shown, this multifunctional dining chair includes a frame 1, on which a backrest 5, a seat cushion 2, and chair legs 6 are fixedly installed. In this embodiment, the frame 1, backrest 5, seat cushion 2, and chair legs 6 all adopt existing structures and their fixing methods are also existing. L-shaped bases 3 are also fixedly installed on both sides of the frame 1. The frame 1 uses a metal frame, and one end of the L-shaped base 3 has multiple mounting holes 3a. The L-shaped base 3 can be fixedly installed to both sides of the frame 1 using fasteners, which can be achieved using existing technology. One end of the L-shaped base 3 is horizontally fixedly connected to a guide shaft 10, and both ends of the guide shaft 10 are movably connected to a support beam 11. Specifically, the support beam 11 has guide grooves 11 that cooperate with the guide shaft 10. a) The support beam 11 can slide or rotate relative to the guide shaft 10, which is also an existing structure. The upper end of the support beam 11 is fixedly connected to the restraining handrail 4, and the lower end of the support beam 11 is fixedly connected to the crossbar 7. The crossbar 7 has a threaded hole one, and the other end of the L-shaped base 3 has a threaded hole two. Locking screws 8 are installed in the threaded holes one and two. Specifically, the locking screws 8 are hand-tightened. Under the action of the locking screws 8, the crossbar 7 and the L-shaped base 3 can be fixedly connected. That is, when the restraining handrail 4 needs to be used, the restraining handrail 4 is made vertical and pulled upward to the limit position. Under the action of the locking screws 8, the crossbar 7 and the L-shaped base 3 are fixedly connected, thereby fixing the restraining handrail 4.

[0018] A magnet 9 is installed on the L-shaped base 3, and an iron plate 12 that attracts the magnet 9 is installed on the armrest 4. When the armrest 4 is folded up, the support beam 11 is horizontal and the iron plate 12 is held by the magnet 9, thereby preventing the armrest 4 from accidentally shaking when the dining chair is used or moved.

[0019] In this invention, when guests bring children to dine at home, the restraining armrests 4 on both sides can be pulled out from the bottom of the dining chair, making them vertical and fixed. In this way, the restraining armrests 4 can prevent children from sliding off the sides of the dining chair. When not in use, the restraining armrests 4 can be stored at the bottom of the dining chair to meet different temporary use needs.

[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
