Description

[Detailed description of the invention] The present invention relates to a gate with a drop bar.

Conventionally, such a gate with a drop bar is disclosed in Japanese Utility Model Publication No. 57-19412, in which a backing plate for supporting a drop bar is fixed inside a hollow vertical beam made of an aluminum profile, and a knob of the drop bar is attached to the lower end of the hollow vertical beam. A gate with a fixed supporting holder has been proposed.

However, such gates require a backing plate and a holder in addition to the gate body, making their manufacture and assembly with the gate body cumbersome, and the screws and twists required for assembly spoil the aesthetic appearance. Since the knobs are attached to and removed from the holder by hand, the user must bend at the waist each time the drop bar is raised or lowered, resulting in poor operability.

In view of these shortcomings, the inventor has conducted extensive research and found that
They succeeded in solving this problem and completed the present invention.

The present invention will be described in detail below with reference to the drawings.

In the drawings, 1 is the gate body. The gate main body 1 is rotatably attached to the gate post 4 via a hinge 41. Further, the gate main body 1 may be made of cast metal such as cast iron or aluminum, or may be made of a molded material such as aluminum or wood. An insertion hole 11 is formed below the end of the gate body 1 on the side where the hinge 41 is not provided. The insertion hole 11
may be formed directly on the gate body 1 upward from the lower end of the gate body 1, or a cylindrical body having an insertion hole 11 may be attached to the gate body 1.
Note that if the insertion hole 11 is formed directly in the gate body 1, there is no distinction between the front and back of the gate body 1, and it can be used for both left and right use, which is preferable in terms of inventory management.

2 is a drop stick. The upper part of the drop bar 2 is inserted into the insertion hole 11 from below so that it can move up and down, but when the lower end of the drop bar 2 touches the ground 5, the upper part of about 20 cm is inserted into the insertion hole 11. If it remains, it is preferable because the wobbling of the drop rod 2 will be reduced. Further, a protrusion 21 is provided on the outer wall of the drop bar 2 in a protruding manner.

3 is a leaf spring material attached to the drop bar 2. The leaf spring material 3 is bent into a waveform as shown in FIG. Further, as a method of attaching the leaf spring material 3 to the drop bar 2, as shown in Fig. 2, a notch 22 is provided in the upper outer wall of the drop bar 2, and the leaf spring material 3 is fitted into the notch 22. do it.

Next, we will describe how to use the gate of this invention.

First, the upper part of the drop rod 2 is inserted together with the leaf spring material 3 into the insertion hole 11 of the gate main body 1. When the gate body 1 is closed, the lower end of the drop bar 2 is inserted into the locking hole 51 of the surface 5, so that the protrusion 21 is pushed against the pressing force due to the repulsive elasticity of the leaf spring material 3 bent into a waveform. Just push it down. In addition, when opening the gate body 1, it is sufficient to push up the protrusion 21 against the pressing force due to the repulsive elasticity of the spring material 3, and at the pushed up position, the drop bar 2 presses the inner wall due to the repulsive elasticity of the spring material 3. It stops, and the gate body 1 becomes freely rotatable.
Therefore, the protrusion 21 only needs to move up and down,
Therefore, it is also possible to operate it with your feet.

As detailed above, the gate of the present invention has an insertion hole formed from below at the end of the gate body on the side where the hinge is not provided, so the insertion hole is not visible from the outside of the gate body and is aesthetically pleasing. In addition, the leaf spring material of the drop bar is not exposed to the outside and can be used for a long period of time as it is prevented from being exposed to the wind and rain or being damaged by other objects, and there is no distinction between the left and right sides of the gate body, making it easy to install. Easy inventory management.

In addition, the gate of the present invention is attached by fitting a leaf spring material bent into a wave shape into a notch provided in the upper outer wall of the drop bar, so that the tops of the waveforms at multiple locations of the leaf spring material are attached to the notch. A pressing force due to repulsion elasticity is exerted in contact with the outer wall of the insertion hole and the inner wall of the insertion hole, preventing the drop rod from wobbling within the insertion hole, allowing it to move up and down smoothly and stopping at any position. The leaf spring material is simply sandwiched between the outer wall of the notch of the drop bar and the inner wall of the insertion hole and does not fall off, and there is no need for fixing means such as pins, making it easy to assemble and having good workability.
