Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting fitting for a channel frame member.

[Conventional technology]

A framework for assembling doors, partition panels, and other core materials has conventionally been constructed as shown in FIGS. 5 to 8.

(1) As shown in FIG. 5, the end face of the channel frame material A is fixed to the back surface of the channel frame material B by welding C.

(2) As shown in Figures 6 and 7, use the L-shaped bent metal piece D, and fix one piece D ₁ to the frame material A with rivets E or welding, and attach the other piece D ₂ to the groove-shaped frame material. It comes into contact with the back side of B and is fixed by screw F or welding.

(3) As shown in Fig. 8, a tapping hole G is provided on the back end of the groove-shaped frame material A, and a tapping hole G is provided on the end surface of the groove-shaped frame material B.
Abut the back sides of and secure with screws F.

[Problem that the invention attempts to solve]

However, when using welding, a skilled welder is required for the work, and since the welded part has unevenness, finishing processing is required to smooth it, which requires a lot of expense, and the use of different materials. Since it cannot be welded, it is fixed with screws, but it requires more man-hours such as drilling and costs more.

The object of the present invention is to provide a connecting fitting that allows groove-shaped frame members to be assembled easily and accurately without the need for complicated steps such as welding and screw fixing.

[Means for solving problems]

The present invention is a connecting fitting that connects one channel-shaped frame member to another channel-shaped frame member at right angles, and the connecting fitting includes a first connecting member that is fitted into one of the channel-shaped frame members; , a second connecting member that clamps the back plate of the other groove-shaped frame member by the first connecting member, and the first connecting member
The connecting member includes a pair of side pieces inserted into the inner side of both side plates of one of the groove-shaped frame members, a bottom piece connecting the bases of the both side pieces, and a bottom piece provided in the center of the bottom piece protruding toward the tips of the both side pieces. The second connecting member has a second connecting member attaching portion, and an elastic side claw that is provided on the side piece to protrude outward and comes into pressure contact with the inner surface of the both side plates, and the second connecting member is attached to the second connecting member attaching portion. a support piece fixed to the bottom surface; a resilient piece disposed parallel to the bottom piece with a predetermined gap between which the back plate of the other channel frame material is inserted;
a connecting piece that connects the ends of the support piece and the elastic piece on the side opposite to the insertion of the back plate; and a back plate of one of the groove-shaped frame members that is provided on the elastic piece so as to protrude toward one side of the bottom and inserted into the predetermined gap. It is characterized by having a protrusion that comes into pressure contact with.

[Effect]

Therefore, both side pieces of the first connecting member are fitted into one of the groove-shaped frame members, and the back plate of the other groove-shaped frame member is fitted between the bottom piece of the first connecting member and the elastic piece of the second connecting member. By inserting into the gap between them, both channel frame members can be assembled at right angles.

be placed parallel to the

As shown in FIGS. 3 and 4, the connecting fitting 10 configured in this way is constructed by inserting the side pieces 12 and 13 of the first connecting member 11 into the side plates 2a and 3a of the groove-shaped frame member B, and Resilient side claws 16 of pieces 12, 13,
17 are pressed against the inner surfaces of the side plates 2a and 3a, and the back plate 1b of the groove-shaped frame material B is inserted into the gap 40 between the bottom piece 14 and the elastic piece 23, and the protrusion 25 is attached to the elastic piece 1b. The back plate 1b is pressed and supported by the elasticity of 23, and in combination, both the groove-shaped frame members A and B can be connected orthogonally by the connecting fitting 10. When making this connection, if the end of the channel frame member B is flush with the outer surface of the back plate 1a of the channel frame member A, as shown in FIG. A cutout portion 1c is formed in a portion of the back plate 1b that comes into contact with the connecting piece 24.

[Effect of idea]

As described above, in the connecting fitting of the present invention, the first connecting member is provided with a pair of side pieces having elastic side claws projecting outward, and the second connecting member fixed to the first connecting member is connected to the first connecting member. An elastic piece is provided that is arranged parallel to the bottom piece of the member to form a predetermined gap, the elastic piece has a protrusion protruding from one side of the bottom, the both side pieces are inserted into one of the groove-shaped frame members, and the One of the groove-shaped frame members is connected by pressing the side claws against the inner surfaces of both side plates of the groove-shaped frame member, and the back plate of the other groove-shaped frame member is inserted into the gap, and the protrusions of the bottom piece and the elastic piece are connected. Since the back plate is supported by pinching pressure, there are the following advantages.

(1) Assembly is possible regardless of whether the frame materials to be connected are made of the same or different materials.

(2) It can be easily assembled without requiring any special skills such as welding technology or jigs and tools such as welding machines and drills.

(3) Connection work is easy with just one touch.

(4) One channel-shaped frame is connected by the elastic side claws, and the other channel-shaped frame is connected with pressure by the protrusions of the bottom piece and the elastic piece, so both channel-shaped frames are connected. It is difficult to remove after connection, and there is no risk of frame displacement.
