Description

[Detailed Description of the Invention] The present invention relates to a notch reinforcing device in a vertical stile of a fitting.

Conventionally, in order to attach a lock to a vertical stile of a fixture, a notch was inserted through it, and when the lock was crimped from the front and back sides with a clamping plate of the lock, the clamping plate was tightened strongly with a screw to remove the notch. There was a problem that a part of the periphery of the part was deformed. The reinforcement structure shown in Utility Model Application Publication No. 56-22289 discloses a technique for reinforcing the side edges of the front and back plates of a sufficiently wide flat door. Conventionally, no technology was known for effectively reinforcing an elongated rectangular notch for attaching a lock cut into a metal shape such as a hollow tubular frame (small).

The purpose of this invention is to solve these problems, and its feature is that an elongated rectangular notch for attaching a lock is formed longitudinally on two opposing parallel surfaces of the hollow profile. At the same time, an insertion part with a tapered part that is slightly press-fitted between the two surfaces on the short side of the rectangular notch, and an insertion part with a tapered part that is equal to or slightly smaller than the short side dimension of the rectangular notch. Insert a reinforcing member integrally having a short side opening and a closing flange portion having a width and a vertical width equal to or slightly smaller than the external dimension of the two side portions into the short side opening of the rectangular notch. That's what I did.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

In FIG. 1, 1 and 1 indicate sliding doors for the entrance, and 2 is a connecting frame.As shown in FIG. has. Specifically, two opposing parallel surfaces 4,
5, a side outer surface part 6 forming a lateral outer surface, and a web 7 near the lateral inner surface. A recessed groove 8 is formed into which the inner frame of the fitting face piece which integrally includes the grid and the glass is fitted.

Therefore, in FIGS. 3, 4, 6, and 2, A is a hollow molded material extruded from metal such as aluminum or aluminum alloy to form the frame 2;
Reference numeral 9 denotes a lock consisting of a female part 9a and a male part 9b, and an elongated rectangular notch 10, for attaching the lock 9.
10 is installed through the two surface parts 4 and 5 along the longitudinal direction. Each of the female part 9a and the male part 9b is provided with a clamping plate 11, 11 having each side slightly larger than each side of the cutout part 10, as shown in FIG. As shown in FIG. 2, it is crimped onto both sides 4 and 5 and screwed with screws 12 and 12.

Reference numerals 13 and 13 denote reinforcing members that are attached to one pair of upper and lower parts of each hollow member A, and the reinforcing members 13 are as follows:
The short side of the rectangular notches 10, 10 is slightly press-fitted between the double-sided parts 4, 5 to prevent the double-sided parts 4, 5 from deforming in the approaching direction.

In FIGS. 4 and 3, the reinforcing material 13 is formed into a U-shape by bending a plate material by press working, and the width g of the intermediate surface portion 14 is equal to the short side dimension G of the notch portion 10. On the other hand, the vertical width e is set to be equal to or slightly smaller than the external dimension E of the double-sided parts 4 and 5 of the hollow shaped material A, and this intermediate surface part 14 allows the double-sided plates 4 and 5 to be shortened. The sides are covered (see Figure 3). Further, the insertion pieces 15, 15 are formed by bending the left and right sides of the intermediate surface portion 14 of the reinforcing member 13 at right angles. That is, in FIG. 4, the insertion portion 21 is constituted by a pair of parallel insertion pieces 15, 15, and the short side opening cover flange portion 22 is constituted by the plate-like intermediate surface portion 14. . The vertical width f of the insertion piece 15 is set to be smaller than the outer dimension E of the double-sided parts 4 and 5, but larger than the inner dimension F, and is inserted and fitted slightly in the direction of arrows M and M. be done. Further, this insertion piece 15 has tapered tip portions 16 formed on the upper and lower sides in FIG. 4 to facilitate the insertion. Furthermore, the base side of the upper and lower sides of the same figure,
That is, a small recess 17 is formed at the bending portion with the intermediate surface portion 14, so that the intermediate surface portion 14 can be fully inserted until it comes into contact with the short side of the notch portion 10 as shown in FIG. In addition, by leaving a sufficient length h of the parallel remaining portions 18, 18 on the upper and lower sides, leaving the taper portion 16 and the recess 17, the clamping plates 11, 11 can be strongly tightened with the screws 12, 12. When the surface part 4,
This effectively prevents convex deformation of the contact portion with the parallel remaining portion 18 of 5.

Next, as shown in FIG. 5, it is preferable to form the reinforcing member 13 into a small block made of plastic or metal, and the dimensions e, f, and g are set in the same manner as in the above embodiment. That is, in FIG. 5, the tapered portion 16
The attached insertion part 21 is in the shape of a square block, and the short side opening closing flange part 22 is formed integrally with this insertion part 21. Note that FIG. 7 is an enlarged view of the main part of FIG. This effectively prevents extreme local deformation of the surface portions 4 and 5 when they are strongly tightened at 12.

Note that the hollow profile A is a vertical frame 2 as shown in Figure 1.
If the width dimension N of the hollow part 3 is small as shown in FIG. becomes minute. However, since the reinforcing members 13 and 13 of the present invention are not inserted along the long sides of the remaining dimensions P and Q, but are inserted along the short sides, even when the width dimension N is small, It has the advantage that it can be inserted into and reinforced.

[Effect of idea]

The present invention has the following significant effects due to the above-described configuration.

As illustrated in FIG. 8, the width dimension N of the hollow part 3
is small, the remaining dimensions P and Q of the surface portions 4 and 5 may become extremely small if the cutout portion 10 having the short side dimension G is provided therethrough. However, in the present invention, the reinforcing material 13 is not inserted along the long sides, but is inserted along the short sides, so that it can be inserted reliably without any inconvenience, and sufficient reinforcement can be achieved.

Tightening screws 12, 12 for lock clamping plates 11, 11
is located closer to the short side as illustrated in Figure 6,
The reinforcing material 13 corresponds to the vicinity of the fastening screws 12, 12 and sufficiently effectively serves to prevent the surface portions 4, 5 from deforming.

The closing flange portion 22 of the short side opening serves as a stopper (positioning during insertion), and it can be easily and securely installed at an accurate press-fitting position (without inserting too deeply).
