Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement in the technique of attaching an elbow pot to a gate.

[Background technology]

2. Description of the Related Art Conventionally, structures such as those shown in FIGS. 3 to 7 have been known for attaching a pot to a gate. That is, a vertically elongated groove 2 with a side opening is provided in the side end surface of the gate 1, and the width of the opening 3 of this groove 2 is made narrower than the width of the internal groove 4, so that the inner groove 4 is opened as shown in FIG. By inserting the slide plate 6 in a freely slidable manner, placing the elbow pot holder 7 against the side end surface of the gate 1, and screwing the bolt 9 inserted into the elbow holder 7 into the slide plate 6, the elbow holder holder can be assembled. 7 can be attached at any height on the side end surface of the gate 1. Here, as mentioned above, by making the groove 2 vertically elongated and making the slide plate 6 slidable, the installation height of the elbow pot holder 7 can be adjusted. This is so that the height can be adjusted when the pot receiving metal fitting 7 is rotatably attached. However, in the conventional example as described above, the depth of the internal groove 4 is set to the depth of the slide plate 6 so that the tip of the bolt 9 can be accommodated, as shown in FIG.
It was much wider than that. When the bolts 9 were tightened to attach the elbow support fitting 7, the slide plate 6 became bent as shown in FIG. 3, and when the bolt was tightened further, the slide plate 6 fell off.

[Purpose of invention]

The present invention was devised in view of the above points, and its purpose is to prevent over-tightening of bolts, suppress deformation of the sliding plate, and create a gate that will not allow the sliding plate to fall off. Provides a structure for mounting the elbow pot.

[Disclosure of invention]

The hinge mounting structure of the gate of the present invention is such that a vertically long groove 2 with open sides is provided on the side end surface of the gate 1, and this groove 2 is connected to the opening 3, the internal groove 4, and the center of the inner groove 4. The width of the opening 3 is narrower than the width of the internal groove 4, and the depth of the internal groove 4 is set so that it can slide freely into the internal groove 4. A protrusion 8 for opening insertion with a protruding length slightly shorter than the depth of the opening 3 is provided on the armrest holder 7, and the armpit holder 7 is inserted into the side end surface of the gate 1. The bolt 9 is inserted into the elbow support fitting 7 with the opening insertion protrusion 8 inserted into the opening 3.
is screwed onto the slide plate 6 slidably inserted into the internal groove 4, and the tip of the bolt 9 is inserted into the central recess 5.
By adopting such a configuration, the above-mentioned conventional problems are solved. In other words, in the present invention, when the bolt 9 is tightened and the slide plate 6 begins to bend, the opening insertion protrusion 8 comes into contact with the slide plate 6, preventing it from being overtightened any further. 4 is slightly wider than the thickness of the slide plate 6,
Since the tip of the bolt 9 is inserted into the central recess 5, the depth of the internal groove 4 is not as wide as in the conventional case, and when the slide plate 6 is slightly deformed by tightening the bolt 9, both ends of the slide plate 6 are pushed into the inner groove 4. This prevents further deformation of the slide plate 6 when it hits the wall.

The present invention will be explained in detail below with reference to Examples. A vertically long groove 2 with an open side is provided on the side end surface of the gate 1 over the entire length of the side end surface. As shown in FIG. 2, this groove 2 has an opening 3, an internal groove 4, and
The center recess 5 is formed by recessing the center of the back. Here, the width of the opening 3 is narrower than the width of the internal groove 4, and the depth of the internal groove 4 is slightly wider than the thickness of the slide plate 6 that can be slidably inserted into the internal groove 4. The elbow socket holder 7 has an opening insertion protrusion 8 protruding from the plate-like part 10, the protrusion length of which is slightly shorter than the depth of the opening 3, and a bolt 9 is inserted into the opening insertion protrusion 8. A bolt insertion hole (not shown) for insertion is bored. In the embodiment, the elbow support fitting 7
1 shows a pot 11 formed at the end of a plate-shaped portion 10, which is an example of a so-called pot hardware. Therefore, the elbow pot body 13 attached to the side of the gatepost 12 for attaching the gate 1 is an elbow hardware with a protruding elbow. A so-called elbow pot is constructed by rotatably inserting the elbow of the elbow hardware into the pot of the pot hardware. Of course, the elbow pot receiving metal fitting 7 attached to the gate door 1 may be an elbow fitting with a protruding elbow, and the elbow pot body 13 attached to the gate post 12 may be a pot fitting having a pot 11. However, the elbow support bracket 7
was applied to the side end face of the gate 1, the opening insertion protrusion 8 was inserted into the opening 3, and the bolt 9 inserted into the bolt insertion hole of the elbow support fitting 7 was slidably inserted into the internal groove 4. By screwing into the slide plate 6 and tightening the bolt 9, the elbow support fitting 7 is attached to a position at an arbitrary height on the side end surface of the gate 1. In this case, the bolt 9
The distal end thereof is accommodated in the central recess 5.

As soon as the bolt 9 is tightened and the slide plate 6 begins to bend, the opening insertion protrusion 8 comes into contact with the slide plate 6 to prevent further tightening. Also, at this time, since the depth of the internal groove 4 is only slightly wider than the wall thickness of the slide plate 6, when the slide plate 6 is slightly deformed by tightening the bolt 9, both ends of the slide plate 6 will come into contact with the back wall of the internal groove 4. The slide plate 6 is designed to be prevented from deforming any further.

[Effect of idea]

As described above, the present invention is to make the width of the opening of the groove on the side end surface of the gate narrower than the groove width of the internal groove, and to create an opening with a protruding length slightly shorter than the depth of the opening in the elbow support bracket. A protruding insertion protrusion is provided, and the elbow support metal fitting is placed against the side end surface of the gate, and the opening insertion protrusion is inserted into the opening, allowing the bolt inserted into the elbow support metal fitting to slide freely into the internal groove. It is screwed onto the inserted slide plate, so when the bolt is tightened and the slide plate begins to bend, the protrusion for inserting the opening will hit the slide plate, preventing it from being over-tightened. It consists of a part, an internal groove, and a central recess formed by recessing the center of the inner groove, and the depth of the internal groove is made slightly wider than the thickness of the slide plate that can be slid freely into the internal groove. Since the tip is placed in the central recess, the depth of the internal groove is not as wide as in the conventional case, and when the slide plate is slightly deformed by tightening the bolt, both ends of the slide plate will hit the back wall of the internal groove, causing further damage. As a result, in the present invention, it is possible to prevent the slide plate from deforming and to prevent the slide plate from falling out of the groove.
