Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hinge device for a gate that allows the door body to be attached to a post with the door body selected to open inward or outward. This invention relates to a hinge device for a gate that fits a vertical stile of a door body into a U-shaped mounting groove of a metal fitting and fastens with screws.

Prior Art Various hinge devices for gates that can hinge the door body in either the inward or outward opening state have been proposed and put into practical use. The one that uses a type of armrest fitting that fits into the vertical frame of the body and fastens with screws has a good appearance, can be firmly fixed to the door body, and is easy to position the armrest fitting to the door body. It is often used for the following reasons.

As shown in FIG. 1A, such a hinge device includes a screw supporting wall 3 on one side of the base 2 in the width direction and a frame holding wall 4 on the other side, which are integrally formed in the same direction and extend in the vertical direction. Using the armrest bracket 1 having a U-shaped mounting groove 5, fit the vertical stile 7 of the door body 6 into the mounting groove 5, and tighten the vertical stile 7 with the screw 8 screwed into the male screw hole of the screw support wall 3. There has been provided a device in which the armrest fitting 1 is fixed to the door body 6 by pressing it against the frame retaining wall 4 (Japanese Utility Model Publication No. 56-177000). However, this hinge device forms a groove 9 on the back side of the stile 7, that is, on the screw 8 side, leaving the upper and lower sides, and the screw 8 is pressed at this groove 9, so the screw 8 is completely removed from the groove 9. The armrest fitting 1 cannot be attached to or removed from the vertical stile 7 unless it is retreated, and the work of attaching and detaching the armrest fitting 1 is troublesome. In addition, in this type of hinge device, the interval between the screw support wall 3 and the stile retaining wall 4, that is, the width of the mounting groove 5 is generally wider than the thickness of the stile 7, so that the stile 7 is closely attached to the stile retaining wall 4. Then, a gap S is created between the screw support wall 3 and the vertical stile 7, and this gap S causes the first
As shown by the two-dot chain line in Figure A, the door body 6 is often installed in an inclined state with respect to the armrest fitting 1.

Further, as shown in FIG. 1B, the tips 3' and 4' of the screw support wall 3 and the frame support wall 4 of the armrest fitting 1 are bent inward at approximately right angles to form a mounting groove 5'. A hinge device has been proposed in which the vertical stile 7' of the door body 6' is made thicker than the other end, and the vertical stile 7' is fitted into the mounting groove 5' (Japanese Utility Model Publication No. 11439/1983). . but,
In this hinge device, the armrest fitting 1 is fitted from the vertical end of the vertical stile 7'.
The work of attaching and detaching is troublesome. Also, in this hinge device, since the width of the mounting groove 5' is wider than the thickness of the stile 7', when the stile 7' is brought into close contact with the stile retaining wall 4, the stile 7' and the screw support wall A gap S is also created between 2 and 3 in Figure 1B due to this gap S.
As shown by the dotted chain line, the door body 6 is often installed in an inclined state with respect to the armrest fitting 1.

When the door body 6 is tilted relative to the armrest fitting 1 in this way, it looks unsightly, and the latch for keeping the gate closed cannot be locked. When it returns to its correct state, the clamping pressure on the vertical stile becomes weaker and the door body comes off.

Purpose of the invention Although the invention is a hinge device of the type in which a vertical frame is inserted into a U-shaped mounting groove and fixed with screws, it is easy to attach and detach the armrest fitting.
Even if there is a gap between the screw support wall and the vertical stile, the door body will not be installed in an inclined position relative to the armrest bracket, and can be installed in the correct position simply by pressing it against the stile support wall. An object of the present invention is to provide a hinge device for a gate.

Structure of the invention According to the invention, the tip of the frame retaining wall is bent toward the screw support wall, and the inner surface of the tip is an inclined surface that is inclined with respect to the surface of the frame retaining wall, and the screw support This is achieved by making the female threaded hole in the wall face the inclined surface, and further making the tip of the screw on the stile side a flat surface perpendicular to its center line.

The base portion 37 is fitted into the groove 35 of the boss member 31. The frame retaining wall 39 has a tip portion 41 bent inward, that is, toward the screw support wall 38 side, to form a support recess 42 between the base portion 37 and the tip portion 41, and the inner surface of the tip portion 41 is bent toward the screw support wall 38 side. 39, the inclined surface 43 has an angle of less than 90 degrees, preferably between 30 and 80 degrees. Two screw holes 44 into which the aforementioned two screws 23 are individually screwed are formed in the screw support wall 38 at locations spaced apart in the vertical direction. Each screw hole 44 faces the inclined surface 43 such that the center line 45 passes through the inclined surface 43.

The width of the mounting groove 40, that is, the distance between the screw support wall 38 and the stile support wall 39, is the width of the vertical stile 15 of the door body 11, and in particular is slightly larger than the width of the side wall 16. In addition, the width of the support groove 42, that is, the base 37
The minimum distance between the end portion 41 and the side wall 1 of the vertical stile 15 is
The thickness is almost the same as that of 6. Further, the distance between the screw support wall 38 and the edge of the tip portion 41 of the frame holding wall 39 is slightly smaller than the width of the vertical frame 15 on the side wall 16 side.

The connecting shaft 22 has a head portion 46 at the upper end, and the shaft portion 47 is connected to the boss portion 33 of the armrest fitting 21,
