BACKGROUND OF THE INVENTION
The present invention relates to a method for assembling a telescopic gate body that is disposed between a suspension column and a door-to-door column and opens and closes by expansion and contraction.
[0002]
[Prior art]
This type of telescopic gate is a pantograph that assembles the link material that constitutes the gate, and opens and closes the opening between the gate pillars by its expansion and contraction.It is equipped with casters, dropping bars, handles, etc. Basically, each end of each frame formed in a frame shape and a plurality of vertical bars arranged between them, a plurality of link members assembled in a pantograph shape, and a crossing portion of link members in different oblique directions are connected. It consists of a rotating shaft. A part of the rotating shaft is slidably attached to the rod and the vertical rail.
[0003]
Conventionally, the telescopic gate body is conventionally constructed by combining a plurality of link members and a rotating shaft in a pantograph shape as a unit, and with the rotating shafts arranged in a vertical line, the end of the upper rotating shaft. On one side, a vertical member or vertical bar material is vertically arranged, and the end of the pivot shaft is fitted into a guide groove formed in the longitudinal direction of the vertical member or vertical bar member, and is slid downward. In addition, it was assembled by connecting the vertical bars on both sides and the vertical bars.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a telescopic gate according to the present invention, wherein a telescopic gate 1 is arranged between a suspension pillar 2 and a door-holding pillar 3. The gate 1 is provided with a handle 4, a lock 5, a caster 6, etc. on the gate main body a. The gate main body a has a plurality of vertical rails 9 arranged between the suspension ledges 7 and the door ledges 8 at both ends. These eaves 7 and 8 and the vertical beam 9 are formed into an elongated frame shape by the eaves members 7a, 7b, 8a and 8b on the left and right sides, and the vertical beam material 9a and the connecting material 10, and a pantograph shape is formed in the inner opening. A plurality of link members 11 a and 11 b assembled together are arranged, and the intersecting portions of the oblique link members 11 and 11 b having different directions are connected via a rotating shaft 12. Rotating shafts 12 corresponding to the upper and lower rows are formed in every other row, and both end portions thereof are formed along the longitudinal direction of the suspension rod 7, door-to-door rod 8 and vertical rail 9 as shown in FIG. The guide groove 13 (see FIG. 3) is slidably engaged (positioned in the portion indicated by the square in FIG. 2). These rotation shafts 12 are set as slide rotation shafts. The other rotation shaft 12 that does not engage with the guide groove 13 is a free rotation shaft (located in the portion indicated by the triangle in the figure). However, the center rotation shaft among the slide rotation shafts engaged with the guide groove 13 is fixed to the suspension base rod 7, the door stop rod 8, and the vertical rail 9, and the fixed rotation shaft 12b (shown by a circle in the figure). Is positioned so as not to slide (see FIG. 9 (f)). Thereby, the gate body a expands and contracts while the rotation shaft 12 excluding the fixed shaft slides in the vertical direction along the suspension groove 7, the door stop 8 and the guide groove 3 of the vertical bar 9. In addition, what is shown by hexagons in the figure is a portion in which the rotation shaft 12 at the end of one link member 11 is slidably engaged with the guide groove 13.
[0008]
Next, a method for assembling the telescopic gate body a will be described. The feature of this method is basically that the telescopic gate body is assembled upward from the lowermost component in a state where the telescopic gate body is placed horizontally.
[0009]
The specific work procedure is as follows.
(A) As shown in FIG. 3, a predetermined number of the suspension base rods 7 at the both ends, the door-to-door rods 8 and the rod members 7a, 8a on one side of the intermediate vertical beam 9 and the vertical beam members 9a are arranged side by side. . As described above, the eaves 7 and 8 and the vertical beam 9 are formed by connecting a pair of left and right eaves 7a and 8a and the vertical beam 9a with a connecting material 10 to form an elongated frame. Here, the left and right saddle members 7a, 8a and the vertical beam member 9a are arranged side by side. A guide groove 13 is formed along the longitudinal direction of each of the eaves 7a, 8a and the vertical beam member 9a, and the guide groove 13 is placed upward.
(B) Next, as shown in FIG. 4 and FIG. 9B, the slide rotation shaft 12a and the fixed rotation shaft 12b are set up vertically on the saddle members 7a, 8a and the vertical beam member 9a. At that time, one end of the slide rotation shaft 12a is slidably attached along the guide grooves 13 of the ribs 7a and 8a and the vertical beam member 9a, and is set up vertically. As shown in FIG. 9 (a), the end of the fixed rotation shaft 12b stands directly on the saddle members 7a and 8a and the vertical beam member 9a, and is fixed by a rivet 14.
9 (a) to 9 (f) show only the example of the vertical beam 9, but the same applies to the eaves 7a and 8a, and the illustration is omitted.
(C) Next, as shown in FIGS. 5 and 9B, one link member 11a is passed through the slide rotation shaft 12a and the fixed rotation shaft 12b. At that time, as shown in FIGS. 6 and 9C, the bush 15 is fitted on the slide rotation shaft 12a and the fixed rotation shaft 12b. Similarly, as shown in FIG. 6, the link member 11a has a free rotating shaft 12c between the ribs 7a and 8a and the vertical beam member 9a and between the vertical beam member 9a and the vertical beam member 9a. Stand through one end. In the figure, only the center of the free rotating shaft 12c is shown, but the other is the same.
(D) After that, as shown in FIGS. 7 and 9D, the other link member 11b is attached to the slide rotation shaft 12a, the fixed rotation shaft 12b, and the free rotation shaft 12c.
(E) Further, as shown in FIG. 8 and FIG. 9 (e), the slide block 16 is attached by sliding along the guide groove 13 from the ends of the other side saddle members 7b, 8b and the vertical beam member 9b. The slide rotation shaft 12a and the fixed rotation shaft 12b are attached to each slide block 16. In addition, since the center part of the free rotating shaft 12c is formed in large diameter, it is not necessary to insert the slide block 16. FIG. A stopper is attached to the free rotating shaft 12c.
(F) Finally, the saddle members 7a, 7b, 8a, 8b on both sides and the vertical beam members 9a, 9b are connected via a connecting member (indicated by reference numeral 10 in FIG. 1), and the other of the fixed rotating shaft 12b is connected. The end is fixed with a rivet 14.
[0010]
By the above process, the door-to-door fence 8, the suspension base fence 7, and the vertical beam 9 are formed, and the link material 11 is arranged in a pantograph shape between them. Since the handle 4, the lock 5, the caster 6, the dropping bar and the like are attached to the gate main body a and raised vertically, the gate 1 is completed.
[0011]
【The invention's effect】
According to the assembling method according to claim 1, it is possible to assemble the structural members such as the eaves and the vertical beam members side by side, so it is necessary to raise or lower the structural members of the gate body a in the vertical direction. There is no, work is easy and easy. In addition, the number of means for holding the constituent members is minimal, and the gate body can be assembled in a contracted state, so that the work space may be small. Therefore, the gate body can be manufactured at low cost.
