Description

[Detailed explanation of the invention] This invention relates to a prefabricated base for steel furniture.In the case of conventional bases of this type, the ends of the vertical frame and the horizontal frame are welded or screwed together after assembly. In addition, necessary parts were used to make the corners of the vertical frame and the horizontal frame at right angles.

Therefore, there are problems in that assembly is troublesome and the number of parts increases.

This idea is intended to solve the above problem, and provides an assembly type base that can easily and firmly assemble the vertical frame and the horizontal frame with one touch at the location where steel furniture is to be installed. The purpose is to

An embodiment of this invention will be described below with reference to the drawings.

Reference numeral 1 designates a vertical frame body, and when the vertical frame body 1 forms upper and lower surfaces 3, 3' by horizontally bending the lower edge E of the main portion 2 in the same direction, the upper and lower surfaces 3, The tip edge of 3' is further bent inward to form a hanging piece 4 and an upright piece 5, and has a U-shaped cross section.

6 is a horizontal frame body, and when the horizontal frame body 6 bends the upper and lower edges of the main portion 7 horizontally in the same direction to form upper and lower surfaces 8, 8', both ends of the upper and lower surfaces 8, 8' The edges are bent further upwards to form upright pieces 9, 9', and the cross section is U-shaped.

Reference numeral 10 denotes a vertical groove provided near the end of the upper hanging piece 4 of the vertical frame body 1, and an insertion piece 11 is formed on the outside of the vertical groove 10.

A chamfered portion 11a having a constant curvature is provided at a corner portion of the insertion piece 11 on the vertically divided groove 10 side.

Reference numeral 12 denotes a long hole provided near the end of the lower surface 3' of the vertical frame 1, and the long hole 12 is parallel to the edge 3 of the lower surface 3'. It is in a position where the insertion piece 16 of the frame body 6 can be inserted.

Reference numeral 13 denotes a missing portion provided near the end of the upper surface of the upright piece 9 of the horizontal frame 6, and a chamfered portion 9a of a constant curvature is provided at the corner of the upright piece 90 facing the missing portion 13. ing.

Reference numeral 14 denotes a long hole provided near the end of the upper surface 8 of the horizontal frame 6, and when the long hole 14 is parallel to the edge 8 of the upper surface 8, both X and the vertical frame 1 The insertion piece 11 is in a position where it can be inserted.

Reference numeral 15 denotes a vertical groove provided near the end of the lower compatible upper piece 9' of the horizontal frame 6, and an insertion piece 16 is formed on the outside of the vertical groove 15.

The corner of the outer edge of this insertion piece 16 and the vertical groove 1 of the rising piece 9'
A chamfered portion 16a having a constant curvature is provided at each corner on the 5th side.
9a' is provided.

Reference numeral 17 denotes a bent piece provided at the edge of the main portion 7 of the horizontal frame 6, which is oriented in the same direction as the upper and lower surfaces 8 and 8' and is in contact with the outer surface of the end of the main portion 2 of the vertical frame 1. It is now accessible.

That is, a gap 18 corresponding to the thickness of the main portion 2 of the vertical frame 1 is provided between the inner surface of the bent surface 17 and the edge of the upper and lower surfaces 8.8'.

Reference numeral 19 indicates two circular dowels provided on the inner surface of the bent piece 17, and reference numeral 20 indicates two circular holes provided on the outer surface of the main portion 2 of the vertical frame body 1.

The circular holes 20 are adapted to fit into each other with the ends of the vertical frame 1 and the horizontal frame 6 completely connected.

Note that chamfered portions 11 a and 16 a are provided at the corners of the insertion pieces 11 and 16 and the upright pieces 9 and 9', respectively.

9at9a' is intended to facilitate bonding with the partner to which they are bonded, and may be used in any other suitable manner (for example, bending the corners).

Since this device is constructed as described above, the main part 2 of the vertical frame 1 is connected to the bent piece 17 provided at the edge of the main part 7 of the horizontal frame 6 and the upper surface 8 as shown in FIG. 2A. It fits into the gap 18 with the edge.

FIG. 2 is a sectional view of this state.

Next, as shown in FIG. 3A, when the upper surface 3 of the vertical frame 1 is strongly pressed downward as shown by the arrow, the vertical groove 10 provided near the end of the upper surface hanging piece 4 and the outer side of the vertical groove 10 are removed. At the same time that the insertion piece 11 is fitted into the missing portion 13 near the end of the upper piece 9 of the horizontal frame 6 and the elongated hole 14 of the upper surface 8, the insertion piece 11 is provided near the end of the upper piece 9 of the horizontal frame 6. The vertically divided groove 15 and the insertion piece 16 on the outside thereof are compatible with the lower end of the upper piece 5 of the vertical frame 1 and the lower surface 3.
' is inserted into the elongated hole 12.

In this case, as shown clearly in FIG. It has not yet been fitted into the circular hole 21.

Therefore, the outer surface of the vertical frame 1 is pressed inward by the height of the dowel 19, but the insertion piece 11 of the vertical frame 1.
Insertion pieces 16 of the horizontal frame 6, and rising pieces 9 on the upper and lower surfaces of the horizontal frame
, 9' have chamfered portions 11a, 16a,
9a and 9a' are provided, so if the upper surface 3 of the vertical frame 1 is strongly pressed downward, the chamfered portions will serve as a guide and slide, as shown in FIG. 4A, the upper surface of the vertical frame 1. 3 comes into close contact with the outside of the upper surface 8 of the horizontal frame 2, and at the same time the dowel 19 of the bent piece 16 of the main part 7 of the horizontal frame 6 comes into close contact with the outside of the upper surface 8 of the horizontal frame 2, as shown in FIG. 4B. Circular hole 2 on the outer surface of the main part 2
0, and the ends of the vertical frame 1 and the horizontal frame 2 are completely connected.

The above operation is the same for the four ends, and by joining all the ends together, the base body is completed as shown in Figure 5.

As described above, according to this invention, the ends of the vertical frame body 1 and the horizontal frame body 6 can be easily connected with a touch, and there is no need to perform means such as welding or screwing for the connection. Easy to assemble by anyone.

Further, the end portions of the vertical frame body 1 and the horizontal frame body 6 overlap each other at a low level at a plurality of locations at the same time.

Not only is it extremely strong after it is completely joined, but it also has various excellent effects such as fewer parts because it forms a right angle without using any other parts, and it can be expected to reduce costs. be.

Moreover, the effectiveness of this invention is that the two horizontal frames are placed parallel to each other with an interval equivalent to the length of the vertical frame, and the vertical frame is attached to each end of the horizontal frame from above. Simply place the main part of the vertical frame into the gap at the end of the frame, and the other member (horizontal frame) can be strongly expanded or pushed. This means that both ends of the vertical frame can be fitted onto each end of the horizontal frame without need.

Moreover, after fitting, the vertical frame body consists of the insertion piece and the groove in which it fits, the circular dowel and the circular hole in which it fits, and the vertical frame body fitted in the gap between the ends of the horizontal frame body. Since the outer surface of the main part has a three-way joint structure with the structure in contact with the bent piece of the frame and the surface, it is possible to assemble even more firmly, making it suitable for use as an assembly type base for steel furniture. This means that the effects can be fully demonstrated.
