Description

[Detailed Description of the Invention] This invention relates to a corner block that is attached to a corner of a shoji frame in a fitting that constitutes a shoji frame using extruded metal sections.

In recent years, shoji frames for fittings have also come to be constructed from extruded metal sections, but when shoji frames are constructed from extruded sections, the cut surfaces of the sections appear at the corners of the shoji frame. However, the cut surface of this profile has the drawback of damaging the groove when the fitting is fitted into the groove of the lintel with a slight inclination in the inward/outward direction, or when the fitting is removed by tilting from within the groove.

Therefore, this invention improves the drawbacks of metal fittings by making it possible to protect the cut surfaces of the sections that appear at the corners of the shoji frame with corner blocks attached to the corners of the shoji frame.

Next, the structure of the proposed corner block will be explained with reference to the drawings of the embodiments. F is a metal shoji frame, and the shoji frame F is composed of left and right vertical frames A, and horizontal frames D attached above and below the vertical frames A. A glass fitting groove is opened inside the horizontal stile D, and an adjustment bar E is opened in the outward groove of the upper horizontal stile D.
It is inserted and inserted so that it can appear and disappear freely. The vertical stile A constituting the shoji frame F has a notch a3 at its upper end, and the remaining cut portion forms a swallowing portion a4 that is narrower than the vertical stile door abutment wall a1, and the adjustment bar E is a part of the vertical stile A. A protruding strip e is provided corresponding to the swallowing portion a4 of the shoji frame F, and the corner block 1 made of synthetic resin is attached to the corner of the shoji frame F to protrude and retract.

The present invention is that, in the corner block 1, the block body 3 is provided with a side plate 13 corresponding to at least the size of the vertical frame swallowing part a4, and the top end piece 2 corresponding to the cut surface B of the vertical frame A is provided at the upper end of the side plate 13. are integrally provided, and a cutout surface C of the swallowing portion a4 is provided on the side of the side plate 13.
A side protrusion piece 2c corresponding to the side protrusion 2c is integrally provided.

Specifically, as shown in Fig. 4, the vertical stile A has a notch a3 cut into the upper end from the cut surface B, and the notch a3 forms a step-shaped swallowing part a4 in the inner and outer directions. A corner block 1 attached to a corner of the shoji frame F in which a protruding strip e corresponding to the swallowing part a4 of the vertical stile A is formed on the adjustment bar E that is inserted into the outward groove of the stile D. , a body part 3 to be inserted into the hollow part a5 of the vertical stile A is provided, and the body part 3 has a swallowing part a4 of the vertical stile A.
A side plate 13 is formed according to the above, and a protrusion 2a corresponding to the cut surface b1 of the swallowing part of the stile door abutting wall a1 is formed on the outside from the upper end of the side plate 13, and a protrusion 2a corresponding to a part of the cut surface b2 of the stile side wall a2 is formed. A ceiling projection piece 2 consisting of a projection piece 2b is provided, and a side projection piece 2c is provided protruding from the side of the side plate 13 corresponding to the swallowing part notch surface C of the vertical door abutment wall a1. Projecting piece 2 of the ceiling projecting piece 2 protruding from the side plate 13
a, the protruding piece 2b, and the side protruding piece 2c are respectively connected to the vertical stile A.
When the corner block 1 is in the lowered state, the top protrusion piece 2 directly covers the stile cut surface B, and the side protrusion piece 2c covers the outside of the stile cut surface C. . When the corner block 1 is raised and the adjustment bar E fitted into the upper horizontal stile D is projected upward, the ceiling piece 2 is separated from the cut surface B of the vertical stile A as the block 1 is raised, but the ceiling piece 2 protrudes by an amount corresponding to the wall thickness t of stile A, so
The ceiling piece 2 is the shoji frame F regardless of the top or bottom of the block 1.
becomes the corner of The side protrusion 2c of the block 1 moves up and down along the stile notch surface C, but since the side protrusion 2c is circumscribed to the stile notch surface C, the side protrusion 2c moves up and down regardless of the top and bottom of the block 1. This is the corner of the recessed part a4.

Since the corner block of the present invention has the above structure, when forming the corner block 1, the side plate 1 corresponding to the swallowing part a4 of the vertical frame A is attached to the block body 3 in advance.
3 is integrally molded, and a ceiling piece 2 corresponding to the cut surface B of the vertical stile A is integrally molded on the upper end of the side plate 13, and a side protrusion piece 2c corresponding to the swallowing part notch surface C is integrally molded on the side of the side plate 13. Then, this corner block 1 of the present invention is attached to a corner portion of a shoji frame F by the same means as the conventional method. For example, the block body 3 is inserted into the hollow part a5 of the vertical stile A, the adjustment bar E is attached to this block 1, and the block 1 can be moved up and down with a screw.

In addition, the concrete implementation of the idea is not limited to the above embodiment, and the shape and structure of the block 1 and the formation positions of the protrusions 2 and 2c are similar to that of the vertical stile A constituting the shoji frame F. It can be changed as appropriate depending on the shape of the horizontal stile B and the adjustment bar E inserted into the horizontal stile B.

Therefore, like conventional corner blocks, the proposed corner block is inserted across the vertical and horizontal frames that make up the shoji frame, making it possible for the adjustment bars to move in and out. Since it has a protrusion that corresponds to the cut surface and notch surface, even if the fitting is tilted and inserted into the groove of the lintel, or removed from the groove, the cut surface or notch of the square frame Since the surface does not directly touch the grooves of the shikimoi, and the protrusions provided in correspondence with the cut surfaces come into contact with them, the grooves will not be damaged when fittings are inserted or removed, and fingers and feet will not be injured. The proposed corner block has a significant practical effect on improving the use of metal fittings.
