Description

[Detailed Description of the Invention] This invention relates to a member support fitting mounting device that can firmly fix a member support fitting to a shoji door frame, a sash frame, or other frame material without directly using screws.

Conventionally, when attaching a member support fitting, such as a pivot support member, to a frame material such as an aluminum sash frame, a method has been adopted in which a screw inserted through the pivot support member is screwed into a threaded hole in the frame material.

However, in the case of this attachment means, the attachment strength is relatively low, and if a large external force acts on the shoji door or the like and the screw hole in the frame material is damaged, there is a problem that the screw hole cannot be repaired.

The object of this invention is to provide a member support fitting mounting device that advantageously solves the above-mentioned problems.

Next, this invention will be explained in detail using illustrated examples.

1 to 4 show an embodiment of this invention, in which a frame member 9 is provided with a flanged groove portion 4, and this flanged groove portion 4 is
It is composed of a groove bottom plate 1, groove side plates 2 connected to both sides in the width direction, and inward flanges 3 connected to the middle part of each groove side plate 2 in the groove depth direction, and each inward flange 3. Notches 5 are provided at mutually opposing positions, that is, at the same position in the longitudinal direction of the frame material.

A holding fitting 6 made of a rectangular steel plate having a central screw hole 10 and a plurality of end screw holes 11 is fitted between the groove bottom plate 1 and the inward flange 3 in the flanged groove portion 4, and is inserted into the notch 5. After being moved to a certain position, both ends of the anti-slip fitting 7 made of a rectangular steel plate with a screw insertion hole 12 in the center are fitted into the notch 5, and the anti-slip fitting 7 is fitted into the holding fitting 6. A screw 13 that is overlapped, inserted into the through hole 12, and screwed into the central screw hole 10.
The anti-slip fitting 7 is fixed to the holding fitting 6 by
The thickness of the anti-slip fitting 7 is set to be equal to or slightly smaller than the thickness of the inward flange 3.

A member support fitting 8 made of a rectangular steel plate with a pivot 14 fixed in the center and screw insertion holes 15 provided at both ends is fitted between each groove side plate 2 and overlapped with each inward flange 3, The through hole 15
The member support fitting 8 is fixed to the holding fitting 6 by a screw 16 that is inserted through the screw hole 11 and screwed into the end screw hole 11.

Figures 5 to 7 show an example in which the member support fitting mounting structure of this invention is adopted for the pivot mounting part of a rotating window, and shows the central part of the upper frame member 17 and lower frame member 18 of the shoji door frame. The member support fitting mounting structure of the above-described embodiment is adopted, and the pivot 14 in the member support fitting mounting structure is fitted into the bearing fittings 21 provided at the center of the upper frame 19 and lower frame 20 of the sash frame. The bearing fittings 21 are fixed to the upper frame 19 and the lower frame 20 by welding, screws, or the like.

As in the embodiment described above, the member support fitting 8 is fitted between each groove side plate 2 and overlapped with each inward flange 3, and the member support fitting 8 is attached to the holding fitting 6.
If it is fixed with screws, the stability of the member support fitting 8 can be significantly improved.

When implementing this invention, the slip stopper 7 may be configured in a cross shape, and the slip stopper and member support fitting 8 may be fixed to the holding fitting 6 with a common screw.

This invention can also be applied to attaching hinges, shoji door opening/closing members, and other arbitrary members to shoji door frames and sash frames.

According to this invention, each inward direction in the flanged groove portion 4 is made up of a groove bottom plate 1, groove side plates 2 continuous to each side in the width direction, and inward flanges 3 continuous to each groove side plate 2. The flange 3 is provided with notches 5 at positions facing each other, and the holding fitting 6 is fitted between the groove bottom plate 1 and the inward flanges 3 in the flanged groove portion 4, and The anti-slip fitting 7 whose end is fitted into the notch 5 is overlapped with the holding fitting 6 and fixed with screws, and the member supporting fitting 8 is fixed to the holding fitting 6 with screws, so the member supporting fitting 8 is fixed to the holding fitting 6 with screws. The holding fitting 6 that holds the groove can be fixed to the flanged groove portion 4 by simple means without being screwed to the flanged groove portion 4 so as to prevent the holding fitting 6 from shifting in the longitudinal direction of the groove and at right angles to the longitudinal direction of the groove. It can be firmly fixed so that it does not move in any direction, and therefore,
This has the effect of solving the problems associated with the conventional method of directly screwing the member support fitting to the frame material.
