Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a flip-up gate, and particularly to one in which the structure for attaching the gate to a post has been improved.

[Prior art and problems to be solved] Conventionally, gates have been known to be mechanically attached to a post via an arm and opened and closed by rotating vertically, but in many cases the gate is attached to the post itself. Since a support mechanism for the gate was attached, troublesome installation and assembly work was required when installing the gate.

[Means for solving the problem] The present invention, as a means to solve the above-mentioned problem, is a flip-up gate that is attached to the top of a post via an arm and is opened and closed by rotating it in the vertical direction. The arm support is fitted and attached, and the arm is attached via the arm support, and the arm support is provided with a rotary shaft bearing that supports the arm so as to be rotatable in the vertical direction, and A biasing means for biasing the arm in the direction of lifting the gate in conjunction with the arm is provided inside, and the biasing means is fixed to the arm support.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a vertical cross-sectional view showing an embodiment of the present invention, in which 1 is a column, 2 is a gate, and an arm 4 that holds the gate 2 via an arm support 3 fitted to the upper end of the column 1 is shown. It is installed.

The support column 1 and the arm support 3 are hollow rectangular cylinders, and as shown in detail in FIG. 2, which shows a cross section in a direction perpendicular to FIGS. A thick fitting part 5 provided at the lower end of the support 3 is fitted and fixed with screws 6 for installation.

A rotary shaft support 7 for the arm 4 is protruded from the side surface of the arm support 3 on the side where the gate 2 is attached. A shaft hole 8 is formed in this rotary shaft bearing portion 7, and a mounting bracket 9 fixed to the lower end of the arm 4 is rotatably supported, and the arm 4 is rotated about this shaft hole 8 in the vertical direction ( Refers to the direction indicated by the arrow X in the figure.The same applies hereinafter.)
It is designed so that it can be rotated. One end of an arm link 11, which forms part of the biasing means 10, is fixed to a mounting bracket 9 that passes through the shaft hole 8 and projects to the other side of the rotary shaft support 7.

The biasing means 10 is formed by connecting a gas spring 13 to the arm link 11 via a link rod 12, and is for biasing the gate 2 in the direction of lifting and opening. The arm link 11 is
It is attached so as to intersect diagonally with respect to the axial direction of the arm 4, and one end is connected to the arm 4 and the mounting bracket 9 as described above, and the other end enters the inside through the opening 14 provided in the side surface of the arm support 3. ing. That is, the arm link 11 moves upward when the arm 4 rotates downward.
When arm 4 rotates upward, it rotates downward, so
The opening 14 has a sufficient length to allow the arm link 11 to move up and down.

The gas spring 13 is attached to a pin 17 to a mounting piece 16 protruding inside the cap 15 of the arm support 3.
It is mounted hanging down so that it can rotate. In addition, the tip of the rod 18 of this gas spring 13 is connected to one end of the link rod 12, and the other end of the link rod 12 is connected to one end of the arm link 11, so that the force that tends to extend the rod 18 is transferred to the link rod 12. stick 1
2 and the arm link 11 are constantly urged to rotate as indicated by arrows A and B. Note that, of course, an expandable coil spring can be used in place of the gas spring 13, and there is no problem in using other means as well.

In addition, in FIGS. 1 and 2, a wheel body 20 is provided at the connecting portion between the link rod 12 and the rod 18, and by slidingly contacting the inner wall of the support column 1, the rotation of each link is controlled. It allows the operations to be carried out smoothly.

Next, an example of the assembly order in the illustrated embodiment will be described. First, attach the gas spring 13 to the mounting piece 16 of the cap 15 with the pin 17, and attach the link rod 1 to the tip of the rod 18 of the gas spring 13.
2, and then attach arm link 1 to link rod 12.
Support 1. Next, the gas spring 13 is folded upward so that the link rod 12 and the arm link 11 are in a straight line, and inserted into the arm support 3 with the connecting portion of the rod 18 and the link rod 12 first. Then open the arm link 11 at the opening 14.
After confirming that it is positioned in the shaft hole 8 of the rotary shaft bearing 7, the cap 15 is fixed, and the assembly of the arm support 3 is completed. Then, the arm support 3 assembled as described above is inserted into the support column 1 with the rod 18 of the gas spring 13 at the beginning, and the fitting part 5 is fitted onto the upper end of the support column 1 and screwed into place. Furthermore, if the mounting bracket 9 of the arm 4 is inserted through the shaft hole 8 of the rotary shaft bearing 7 and rotatably inserted into the arm link 11 that has been positioned in advance on the opposite side of the arm 4, it is fixed with a nut 19. Assembly is easy. Of course, other assembly orders may be used.

Next, the operation in this embodiment will be explained. First, when the gate 2 is opened, the rod 18 of the gas spring 13 tries to extend downward within the support 1 and pulls the link rod 12 downward, and the arm link 11 is also pulled downward at the same time. For this purpose, the arm link 11 and the link rod 12 are urged to rotate so as to be positioned on a straight line connecting the shaft hole 8 and the tip of the rod 18.

Then, when the gate 2 is rotated downward, the arm 4
As the arm link 11 rotates, the arm link 11 reversely rotates upward and pushes the rod 18 upwardly through the link rod 12 against the bias of the gas spring 13. Therefore, the momentum of the rotation of the gate 2 is reduced, and the rotation is performed slowly and stably.

When opening the gate 2, the arm link 11 rotates in the same direction as the direction in which it is biased by the gas spring 13, that is, in the biasing direction, so that the gate 2 can be easily lifted. Become.

Note that the internal and external shapes and structures of the pillar 1, the gate 2, the arm support 3, etc. are not limited to the illustrated example.

[Effects of the invention] As explained above, the invention according to the present invention allows the arm support to be fitted to the upper end of the column by providing the rotary shaft bearing and the biasing means in the arm support. It can be easily installed by simply fixing it, and has the effect of simplifying the structure and assembly.
