Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a frame of various panels for fittings such as a lightweight steel door or a partition panel.

[Prior Art] In a panel structure of a lightweight steel door, there is a frame as a strength member, and a space surrounded by the frame is filled with a core material or a heat insulating material, and the surface is further covered with a surface panel material. It is like.

 A conventional frame will be described with reference to FIG.

The frame 1 is composed of upper and lower lateral force bones 2 and left and right longitudinal force bones 3. The cross sections of the lateral force bone 2 and the longitudinal force bone 3 are U-shaped. The left and right end portions of the lateral force bone 2 are flattened by cutting off both width bending portions, and both ends are fitted into the concave portions of the longitudinal force bone 3, and the left and right ends of the lateral force bone 2 and the longitudinal force bone 3 Are joined at the upper and lower ends.

[Problem to be Solved by the Invention] As described above, the conventional frame has a welded structure. For this reason, a skilled welder is required to manufacture the frame, and the welding work is significantly less efficient than machining, assembling work, etc., and also requires work such as strain removal after welding. Workability was also bad.

In addition, a welding line is required as a manufacturing line in addition to a series of assembling operations, so that the number of steps is increased, the work flow is complicated, and the productivity is sometimes poor.

In addition, the productivity is poor and equipment for welding is required, which has caused an increase in cost.

The present invention has been made in view of the above circumstances, and aims to provide a frame body having no welded structure.

[Means for Solving the Problems] The present invention includes a lateral force bone, a longitudinal force bone, and a corner fitting bent at a right angle. The engaged portions each have a gap corresponding to a plate thickness in which the corner fitting can be inserted between the engaging portion and the surface of the power bone, and have a pair of engaging pieces facing each other. Attachment portions are formed at both ends of the fitting, and the attachment portion has a pair of symmetrical hooks having an arrowhead formed at the tip and separated, and one attachment portion of the corner fitting is provided. A laterally engaged bone is inserted between the two engaging pieces of the engaged part, an arrowhead penetrating the engaging piece is engaged with the engaging piece, and a local engaging part of the corner fitting is attached to the longitudinally strong bone. The lateral force bone and the longitudinal force bone were inserted into the engaged portion between the two engaging pieces, the arrowheads penetrating the engaging pieces were engaged with the engaging pieces, and the corner members were connected to each other. thing Wherein the engaged portion is provided so as to protrude on the inner surface side of the lateral force bone and the longitudinal force bone, and the corner fitting connecting the lateral force bone and the longitudinal force bone is an inner surface side of the lateral force bone and the longitudinal force bone. Is characterized in that

[Action] The lateral force bone and the longitudinal force bone are connected at right angles via corner fittings to form a frame. The connection between the lateral force bone and the corner fitting, the connection between the longitudinal force bone and the corner fitting only requires engaging the engaged part of the lateral force bone and the longitudinal force bone with the engaging part of the corner fitting, such as welding.
No fixing means is required. In addition, the corner fitting is provided on the inner side of the power bone and is covered with the power bone and does not appear in the appearance, so that the design is excellent.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the frame 5 according to this embodiment
Is formed by connecting the end of the lateral force bone 6 and the end of the longitudinal force bone 7 by a corner fitting 8.

Next, each member of the frame 5 will be described with reference to FIGS.

As shown in FIGS. 3 and 4, the lateral force bone 6 has a U-shaped cross section, and the left and right ends are cut off at the bent portions 9 to form a flat tongue 10.

Engagement portions 11 are formed at required positions from both left and right ends.

The engaged portion 11 is located at the center in the width direction of the lateral force bone 6 and the lateral force bone 6.
The engagement pieces 12a, 12b are punched inwardly symmetrically with respect to the long axis of the workpiece, and the engagement pieces 12a, 12b are stepped by the plate thickness of the corner metal fitting 8 and folded inward in steps. It is.

 The longitudinal force bone 7 is shown in FIG. 5 and FIG.

The cross section of the longitudinal force bone 7 is the same as that of the lateral force bone 6, and forms an engaged portion 11 having the same structure as described above at required positions from both ends.

Next, the corner fitting 8 is shown in FIG. 8 and FIG.

The corner fitting 8 is formed by bending a plate having substantially the same width as the inner size of the recess of the lateral force bone 6 and the longitudinal force bone 7 at a right angle, and fitting the bent portion to the engaged portion 11. The attachment part 13 is formed.

The engaging portion 13 has a separation groove 14 cut in the center and the separation groove.
It has a pair of hooks 16a and 16b separated by a slit groove 15 cut symmetrically with respect to 14.

The hooks 16a, 16b have projecting tips, and the tips have arrowheads 17a, 17b for retaining.

The lateral force bone 6 and the longitudinal force bone 7 are connected via the corner fitting 8, and this connection will be described with reference to FIG.

First, the lateral force bone 6 causes one of the longitudinal force bones 7, for example, the lateral force bone 6 to engage the corner fitting 8.

The attachment of the lateral force bone 6 and the longitudinal force bone 7 is performed by attaching the engaging portion 13 to the engaged portion.
Perform by plugging into 11. Corner metal fitting 8 is lateral force bone 6
Is guided to the bent portion 9. At this time, hooks 16a, 16
Due to the wedge action of the arrowheads 17a, 17b of b and the engaging pieces 12a, 12b, the hook pieces 16a, 16b are bent toward the center side, and the arrowheads 17a, 17b climb over and over the engaging pieces 12a, 12b. The rest is restored by elasticity, and the arrowheads 17a, 17b engage with the engagement pieces 12a, 12b, respectively,
The engaging portion 13 and the engaged portion 11 cannot be removed.

 Next, the longitudinal force bone 7 and the corner fitting 8 are engaged.

The engagement between the longitudinal force bone 7 and the corner fitting 8 is the same as the engagement between the lateral force bone 6 and the corner fitting 8, and a description thereof will be omitted below.

Thus, the lateral force bone 6 and the longitudinal force bone 7 are connected to each other at right angles through the corner fittings 8 fixed to the inner surfaces of the both force bones.

The frame 5 is completed by connecting the lateral force bone 6 and the longitudinal force bone 7 at four corners with the corner fittings 8.

Note that the shapes of the engaged portion 11 and the engaging portion 13 can be variously changed. For example, as shown in FIG. 11, the engaging pieces 12a, 12b of the engaged portion 11 are provided in opposite directions, and the hook pieces 16a, 1 of the engaging portion 13 are provided.
For example, 6b is provided at both ends of the width of the corner fitting 8.

Further, a front panel is fixed to the frame body 5 by an appropriate means such as bonding or screwing and a combination of a plurality of means.

[Effects of the Invention] As described above, according to the present invention, no welding is required for the production of the frame and only the assembling work is required, so that a skilled welder is not required and the man-hour is greatly reduced. In addition, the manufacturing cost can be reduced, the equipment cost can be reduced, and the corner fitting is not exposed to the outside, so that the design is not impaired.
