Description

[Detailed explanation of the idea] The present invention relates to a simple chair.

In other words, the seat body etc. can be easily assembled by tightening bolts without welding or the like by bending the pipes, etc. Moreover, sufficient overall strength can be ensured and the structure can be made compact. It is provided to enable suitable implementation.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a perspective view of the entire chair, and A shows the entire front leg frame. and both back rods 3,3
is extended and formed, and the upper ends of both back rods 3.
formed by one pipe so as to be connected by
A backrest 9 is attached between both back rods 3, 3.

Reference numeral B denotes a rear leg frame, which is formed by a single pipe such that the front parts of both horizontal bars 5,5 extending horizontally forward from the upper part of the rear leg bars 4,4 are connected by a horizontal bar 10. .

C is a seat plate having a width corresponding to the length between the upper parts of the front leg rods 1, 1, and a width corresponding to the diameter of both horizontal rods 2, 5 at the center of both sides of the seat plate C. Both protrusions 6, 6 are formed which protrude by the length, but the seat plate C can also be covered with a seat.

In addition, the protrusions 6, 6 on both sides of the seat C are inserted between the upper and lower horizontal rods 2, 5 on both sides, but the two horizontal rods 2 that approach the front and rear of both the protrusions 6, 6 Oak holes 11.11 are fixed by welding on the lower surfaces of the nuts H1 and 11, and oak holes 12.12 are installed in the vertical holes 12. 11
It is installed so that a bolt 7.7 that can be screwed into can be inserted,
A spacer 13.13 that can fit into the nut 11 and bolt 7 is interposed between both horizontal rods 2 and 5, and a spacer 14.
14 and configure it.

The rain rear leg rods 4, 4 are configured to be wide so that they protrude outward from both front leg rods 1, 1.

Therefore, the front leg frame A is overlapped with the rear leg frame B, and both the protruding parts 6, 6 of the seat body C are inserted between the horizontal bars 2, 2 and the horizontal bars 5, 5, and the spacers 13.13 Insert the bolts 7 and 7 to be inserted into the horizontal rods 5 and 5) 1)
1.11 and tightened, the whole can be assembled by fitting the spacer 14.14 to the head of the bolt 7.7.

In the assembled state, both parallel horizontal rods 2 and 5 are long, resulting in a structure that works advantageously for the holding force of the bolt 7.7.

Also, when these chairs are stacked, as shown in Figure 9,
The spacers 14.14 of the upper chairs come into contact with the upper part of the horizontal rod 2, allowing stable stacking.

In this way, the present invention is designed so that the rear ends of both the horizontal rods 2, 2 extending horizontally rearward from the upper portions of the front leg rods 1, 1 are bent in the -E direction and connected at the upper ends of the back rods 3, 3. are extended to form a front leg frame A, and a rear leg frame B is formed by connecting the front parts of both horizontal levers 5, 5 extending horizontally forward from the upper part of the rain rear leg levers 4, 4, Both protruding parts 6.6 protruding from both sides of the seat body C are inserted between both horizontal rods 2, 2 of the front leg frame A and both horizontal rods 5, 5 of the lower rear leg frame B. , Since the assembly was configured by tightening both the upper and lower horizontal rods 2, 5 in front and behind the protruding parts 6, 6 with pole l-7, the front leg frame A and the rear leg frame B were overlapped and therebetween. It can be easily assembled by inserting the seat plate C and tightening with bolts 7, and can be mass-produced in a knock-down manner without the need for welding, and has a compact structure with sufficient overall strength. It has the feature that it can be carried out suitably.
