Definitions

• the invention relates to furniture, in particular, to collapsible furniture for seating.
• This design allows you to relatively quickly assemble-disassemble the product, but also contains metal relatively complex and expensive parts
• the objective of the invention is to simplify the assembly and disassembly of the chair, which are performed manually without the use of tools.
• Another objective is to simplify and reduce the cost of the structure and reduce the time of assembly and disassembly of the chair.
• the chair is collapsible, contains a base, legs, back, knots of fastening the legs to the base and a tightening unit mounted under the base, while
• the base is made in the form of a box, the corners of which are provided with guides for installing the legs,
• the tightening node is placed at the middle of the guides and is made in the form of flexible ring loops connecting diametrically opposite legs in pairs,
• the ring hinges are provided with a twisting element.
• the twisting element is made in the form of twisting - sticks.
• each node for attaching the legs to the base is provided with at least one latch.
• each guide the fixation of the attachment node is made in the form of a threaded element, one end screwed into the leg, and the other passing through the hole in the guide connected to the annular loop of the tightening node.
• the specified implementation of the device allows to simplify and cheapen the design and reduce the time of assembly and disassembly of the chair, as well as to simplify the assembly and disassembly of the chair, which are performed manually without the use of a tool.
• FIG. 1 shows a general view of a collapsible chair
• FIG. 2 shows the fastening of the legs to the guides of the base using flexible loops, respectively, before and after twisting them with a stick, bottom view;
• FIG. 3 shows the fastening of the legs to the guides by means of threaded elements - studs by twisting flexible loops;
• FIG. 4 a side view shows the location of the flexible screed loop at the midpoint of the guide.
• collapsible chair contains a base 1, legs 2 and a back 3.
• the base 1 is made in the form of a box, the corners of which are provided with guides 4 for installing legs 2.
• each attachment point of the legs 2 to the base 1 is provided with at least one latch 7.
• a hole 8 is formed in each guide 4, the clamp 7 of the attachment node is made in the form of a threaded element with a hook for communication with the ring loop 5 of the tightening node, and screwed onto the screw passing through the holes in the leg and the guide with the other end.
• the ring loops 5 of the tightening element are at the level of the middle of the guides 4.
• THE CHAIR IS ASSEMBLED IN THE FOLLOWING IMAGE.
• the legs 2 are inserted into the guides 4, ring loops 5 are inserted over, as shown in FIG. 2 and FIG. 4, and with the help of twisting sticks 6, the ring loops are twisted with maximum effort.
• the legs are pressed against the guides and held at the expense of friction. The back is put on back legs.
• the legs 2 are inserted into the guides 4, threaded elements 7 are inserted, as shown in FIG. 3, ring loops 5 are thrown onto opposite hooks and twisted as in the first embodiment.
• the proposed design of the chair allows you to simplify the assembly and disassembly of the chair, which are performed manually without the use of tools.
• the proposed device allows you to simplify and reduce the cost of the design and reduce the time of assembly and disassembly of the chair.
