Description

  The present invention relates to a gate. More specifically, the present invention relates to a gate that is accurately assembled by providing a recess in a hinge.

  Generally, as a gate installed at a boundary between a site of a house and a road, there is a gate including a door, a pillar, and a hinge. A hinge used for such a gate is usually composed of a rotating piece for connecting with the door and a fixed piece for connecting with a support.

  Patent Document 1 discloses a structure including a door, a pillar that supports the door, a hinge, and a decorative plate on the surface of the pillar. A protrusion for accurately connecting the door is provided on the surface of the hinge that rotates with the door. Therefore, when this rotating piece is used as it is as a fixed piece, this convex portion comes into contact with the support, the contact area between the support and the fixed piece becomes small, and the fixed piece cannot be firmly fixed. There is.

  The fixed piece 23 is provided with a linear hole 23b into which the rotary shaft 13 of the hinge 4 is fitted and a bolt passage long hole 23c through which a fastening bolt passes. The fixing piece 23 and the suspension base 2 are fixed by the two bolts that have passed through the bolt passage elongated hole 23c. Further, the fixed piece 23 is provided with four recesses 23a which are grooves in a direction parallel to the straight hole 23b.

(Gate assembly method)
5A to 5C, a hinge manufacturing process of the rotating piece 11 that constitutes the hinge 4 will be described, and then a door fixing process of fixing the components of the hinge 4 to the door 5 will be described.

  As described above, FIG. 5 is an explanatory view of the manufacturing process of the rotating piece 11 of the hinge 4 of the gate 1 according to the first embodiment. FIG. 5 (A) shows the common original piece 10 before being processed in the hinge manufacturing process, and FIG. 5 (B) shows the rotating piece 11 after being processed in the hinge manufacturing process.

  In the lower diagram of FIG. 5 (A), the common original piece 10 is a long aluminum extruded shape member that extends downward from the omitted curve. The common original piece 10 is provided with one linear hole 10b along the lengthwise direction, and four concave portions 10a which are linear grooves are provided in parallel with the linear hole 10b. . The cross section of the recess 10a is substantially U-shaped as shown in FIG. Since the straight hole 10b and the concave portion 10a are provided along the long direction, when the common original piece 10 is cut in a plane perpendicular to the long direction, the cross section of the cut member is All have the same shape. Further, since the common original piece 10 has the plurality of recesses 10a, the rotating piece and the fixed piece used for the gate having different opening and closing directions of the door as in the first and second embodiments are manufactured from the same shape member. be able to.

  The rotating pieces 11 and 12 and the fixed pieces 21, 22 and 23 used in the first to third embodiments are all manufactured by processing the same common original piece 10. The rotating piece 11 cuts the common original piece 10 along a plane perpendicular to the lengthwise direction of the common original piece 10, cuts the removing portion 11d, provides two bolt passage holes 11c, and finally chamfers or the like. It is manufactured by finishing. Here, “formed” of “formed from the same shape” in the claims means “produced by simple processing such as cutting or drilling”.

The rotary piece 12 shown in FIG. 6 is also manufactured by the same process as the rotary piece 11 of FIG. That is, the rotary piece 12 cuts the common original piece 10 along a plane perpendicular to the lengthwise direction of the common original piece 10, cuts the removing portion 12d, provides two bolt passage holes 12c, and finally chamfers, etc. It is manufactured by finishing the process.
As for the fixing piece 21 shown in FIG. 7, the removal portion 21d is cut and a bolt passage elongated hole 21c is provided instead of the bolt passage hole 11c. The fixed pieces 22 and 23 shown in FIGS. 8 and 9 are cut along a plane perpendicular to the lengthwise direction of the common original piece 10 to provide bolt passage long holes 22c and 23c, and finally finish processing such as chamfering. It is produced by doing.

  A common member 10 having a recess 10a has a hinge manufacturing process in which a rotary piece 11 and the like and a fixed piece 21 and the like can be manufactured by subjecting the common original piece 10 to a simple cutting process and a drilling process. The hinge 4 that constitutes the gate 1 can be manufactured by simple processing. Therefore, the members can be made common and the cost can be reduced.

  After the rotating piece 11 and the fixed piece 21 are manufactured in the hinge manufacturing step, the door fixing step is performed in which the positioning projection 7a of the door 5 is inserted into the positioning recess of the rotating piece 11 and fixed by bolts. At this time, a mounting back plate provided with bolt holes is used on the door 5 side, and the mounting back plate and the bolt are screwed together to fix the door 5 and the fixing piece 11 and the like.

  The fixing pieces 21 and the like are fixed to the suspension base 2. In this case, in order to secure the horizontalness of the door 5, the spacer 14 or the like is sandwiched between the fixed piece 21 or the like and the suspension base 2, and the gap is adjusted.

  The gate is completed by inserting the straight hole 11b of the rotary piece 11 fixed to the door 5 into the rotary shaft 13 of the hinge 4 inserted into the straight hole 21b of the fixed piece 21.

  In addition, in the above-mentioned embodiment, although the support structure was described as the suspension base column directly fixed to the ground, the support structure is not particularly limited thereto. For example, a member that can support the door 5 by being fixed to another member is applicable.
