Description

[Detailed description of the invention] In many cases, rotating objects such as windows, container doors, or the peripheral walls of truck beds must be rotated 180 degrees and locked at those positions. The locking device for these rotating bodies includes a receiving hole that extends perpendicularly to the axis and extends toward the supporting frame in the rotating body, which is rotatably attached to both sides of a support frame fixed to the base by a pivot. A guide groove is drilled in the support frame and is orthogonal to the pivot, so that one wall exists on one side of the guide groove when viewed from the pivot, and the other wall exists on the other side, and the slider is placed on the center line of the pivot. The slider is provided with a pin that can be slid freely in the guide groove, the base end of which is fixed to one side of the slider, and the tip of which is bored into one wall, and which protrudes outward through the guide hole. A second pin is fixed to the other end of the slider and protrudes outward through the other guide hole whose tip is bored in the other wall, and a compression spring is installed between the one side of the slider and the one wall. A compression spring is attached between the other side of the slider and the other wall, an operating part is provided on the slider, and either the tip of one pin or the other pin is removably fitted into the receiving hole. It is what it is.

The configuration of the present invention will be explained below with reference to drawings of embodiments of the present invention.

First, we will explain the correspondence between the symbols on the drawing and the names of their parts. 1 is the base, 2 is the support frame, 3 and 4 are the pivots, 5 is the rotating body, 6 is the receiving hole, 7 is the guide groove, and 8 is one side. wall, 9 is the other wall, 10 is a slider, 11 is one guide hole, 12 is one pin, 13 is the other guide hole, 14
15 is a compression spring on one side, 16 is a compression spring on the other side, and 17 is an operating portion.

Pivots 3 are mounted on both sides of the support frame 2 fixed to the base 1.
A receiving hole 6 is provided in a rotating body 5 which is rotatably mounted by a rotary member 4 and extends toward the support frame 2 perpendicularly to the pivots 3 and 4.
wear it. The base 1 is, for example, a window frame, a container, a loading platform, or the like.

A guide groove 7 which crosses the pivots 3, 4 and is perpendicular to the pivots 3, 4 is bored in the support frame 2 in a substantially elongated hole shape.

One wall 8 is provided on one side of the guide groove 7 when viewed from the pivots 3 and 4, and the other wall 9 is provided on the other side.

A slider 10 is slidably provided in a guide groove 7 on the center line of the pivots 3 and 4.

A one-sided pin 12 is provided whose base end is fixed to one side of the slider 10 and whose tip end projects outward through a one-sided guide hole 11 bored in one side wall 8.

A second pin 14 is provided whose base end is fixed to the other side of the slider 10 and whose tip extends outward through a second guide hole 13 bored in the second wall 9.

The one pin 12 and the other pin 14 are slidable through the one guide hole 11 and the other guide hole 13, respectively.

One compression spring 15 is installed between one side of the slider 10 and one wall 8, and the other compression spring 16 is installed between the other side of the slider 10 and the other wall 9. In the figure, one compression spring 15 and the other compression spring 1
6 are wound around one pin 12 and the other pin 14, respectively.

For example, an operating section 17 is fixedly provided on the slider 10.

Either the tip of one pin 12 or the tip of the other pin 14 can be removably fitted into the receiving hole 6.

Since the present invention has such a configuration, its functions and effects are as follows.

The support frame 2 is fixed to the base by screws 18, for example.

In both figures, the state in which the pin 12 is fitted into the receiving hole 6 is shown.
is locked in the upper position.

When a downward force is applied to the operation part 17, the slider 10
The pin 12 is guided by the guide groove 7 and slides downward against the force of the compression spring 16 on the other hand, while the pin 12 is guided by the guide hole 11 on the other hand and comes off from the receiving hole 6. , 4. During the rotation, the operating portion 17 is released, and when the operating portion 17 is further pushed upward against the force of the compression spring 15, the tip of the other pin 14 is retracted.

In this state, when the rotating body 5 is further rotated and the receiving hole 6 faces the tip of the other pin 14, the operating part 17 is released, and the other pin 14 is fitted into the receiving hole 6 by the force of the one compression spring 15. , the rotating body 5 is locked.

When the rotating body 5 enters the locked state from the rotating state, the operating part 17 is released and the rotation continues with the other pin 14 protruding, so that the slope at the entrance of the receiving hole 6 and the slope at the tip of the other pin 14 are Use the other pin 14
It is also possible to lock it while pushing it in.

When moving from the locked state to the rotating state, without operating the operating part 17, force is applied to the rotating body 5 using the slope at the exit of the receiving hole 6 and the slope at the tip of the other pin 14. It can also be rotated. In this way, according to the present invention, an effective device capable of locking the rotating body can be obtained, which is of great practical value.

[Brief explanation of drawings]

Both FIGS. 1 and 2 are front views in the locked state, but the operating section is removed in FIG. In the figure, 1 is a base, 2 is a support frame, 3 and 4 are pivots, 5 is a rotating body, 6 is a receiving hole, 7 is a guide groove, 8 is one wall, 9 is the other wall, 10 is a slider, 11 1 is a guide hole on one side, 12 is a pin on one side, 13 is a guide hole on the other side, 1
4 is the other pin, 15 is one compression spring, 16 is the other compression spring, and 17 is an operating section.
