Description

[Detailed description of the invention] Conventionally, the vertical and horizontal frames of fittings, especially sliding doors, are connected and fixed via L-shaped corner fittings, but the pieces of the fittings are connected to the second
As shown in the vertical stile in the figure, the purpose was achieved by screwing one piece to one stile and tightening the other piece along with the seat plate to the inner wall 2d of the other stile with screws.

However, during long-term use, the clamped stile is held in place by friction, which has the disadvantage that the tightening becomes loose and the vertical stile comes out.

The present invention relates to a stile connection structure that improves the above-mentioned drawbacks.

The present invention will be described below with reference to embodiments with reference to the drawings.

FIG. 1 is a front view showing a state in which a frame around a sliding door or the like, that is, a vertical stile and an upper stile are connected.

FIG. 2 is a longitudinal sectional front view of the vertical stile and the lower stile connected together.

3 is a side sectional view taken along line AA' in FIG. 2, FIG. 4 is a side sectional view taken along line 13-B' in FIG. 1, and FIG.
, c' side cross-sectional view.

FIG. 6 is a plan view of the fixture, which is the main part of the present invention.

(If viewed from the assembly drawing in Figure 2, this corresponds to the bottom view.

) FIG. 7 is a front view taken along line [)-D' in FIG. 6, and FIG. 8 is a side sectional view taken along line E-E' in FIG. 6.

In the embodiment, the lower stile and the upper stile that constitute the surrounding frame of the fittings are approximately the same shape, and the lower stile has a cross-sectional shape that is similar to the inner and outer vertical walls 2a.
Gaya) It's big.

The cross-sectional shape of the vertical stile 1 is H-shaped as shown in FIG.

As shown in FIG. 9, the vertical stile and the horizontal stile 2 having the cross-sections shown above are brought into abutment against the vertical stile and secured by tightening with L-shaped corner hardware or the like.

The horizontal stile 2 has an H-shape as a whole, but between the inner and outer vertical walls 2a, there is a connecting inner wall 2b that integrally connects the left and right vertical walls in the figure, and an inner wall that spans in the longitudinal direction and has a notch 2c in the center. 2d
It is composed of

Note that it is preferable to use aluminum alloy shapes for both the vertical and horizontal stiles.

Reference numeral 3 is an L-shaped corner fitting which is brought into close contact with the connecting inner wall 1a of the vertical stile 1 from the outside of the vertical stile, and is fixed to the corner fitting 3 with screws 4 passing through the inner wall from the inside.

Therefore, since the vertical stile and the corner fitting 3 are screwed together, they are completely fixed to each other.

In the example, it is screwed at two places.

On the other hand, the other piece 3a of the corner fitting is inserted between the connecting inner wall 2b of the horizontal stile, that is, the lower stile in this embodiment, and the inner wall 2d having a notch 2c in the center. It is screwed into a screw hole provided in the corner fitting 3 with a screw 4 through a plate 5.

Therefore, the side stile 2 is held between the corner metal fittings 3 and the seat plate 5 which are tightened with screws 4, and is temporarily fixed by the static friction of the surfaces thereof.

However, over time, due to external shocks such as vibrations, the tightening force on the adhering surfaces of the horizontal stile becomes loose, causing the stile to separate from each other and be pulled out.

Therefore, this drawback is solved by the following fixing metal fittings which are simply added to the conventional mechanism so that the vertical and horizontal frames will not be separated.

An appropriate mounting position for the fixing fitting 6 is an intermediate position between the seat plate 5 and the corner block 7.

In the enlarged views of FIGS. 6 to 8, the fixing fitting main body 6a is shorter than the seat plate 5 and at first glance appears to have the same function as the seat plate, but in FIGS. 6b is integrally formed, and the distal end thereof is provided with a locking pawl 6c that engages with a locking groove 8, which is a notch provided in the inner wall 2b of the horizontal stile 2.

Therefore, when the fixing fitting main body 6a is tightened and fixed to the corner fitting 3 with the screws 4, the fixing fitting 6 forms an almost inverted parallel shape in cross section, and the inner wall 2d is in contact with the corner fitting 3 at the portion where the overhanging piece 6b comes into contact with the corner fitting 3. Since it is a notch, the overhanging piece 6b comes into close contact with the corner fitting and enters into the notch 2C of the inner wall 2d.

At this time, the locking pawl 6C engages with the locking groove 8 of the inner wall 2d that has been provided in advance, so once the horizontal stile 2, corner fittings 3, and fixing fittings are tightened with the screws 4, they will be secured by the action of the locking pawl 6c. It is impossible for their positional relationship to change.

Since the structure is as explained above, it is possible to finely adjust the mutual angle of the frames using the L-shaped corner fittings during installation, as before, and the addition of fixing fittings, which are simple parts, helps prevent shocks caused by long-term opening and closing of the fittings. This is an extremely practical device that can prevent the stile from being pulled out.

It can be applied not only to fusuma but also to fittings such as shoji and doors.
