Description

[Detailed Description of the Invention] The present invention relates to a mechanism for preventing a jack handle from falling.

Conventional mechanisms for preventing the handle from tipping over on garage jacks include a type that manually activates a lever and a type that uses a return spring to hold the handle, but the former is inconvenient to handle, so the latter return spring is currently the mainstream. It's summery. However, even if a return spring is installed, if a human body touches the steering wheel or if the steering wheel begins to fall slightly due to an external shock, the steering wheel will fall due to its own weight, causing injury to people and vehicles.

This invention was made to solve the above problems, and has a simple structure that uses a combination of a rod and a guide groove on the jack handle to ensure automatic locking, and also allows for easy release using a foot pedal. The object of the present invention is to provide a mechanism for preventing the jack handle from falling.

Therefore, the mechanism for preventing the jack handle from falling down of the present invention includes a guide fixed to the lower part of the jack handle and having an occluded groove for locking and a long groove on the release side connected to this groove, and a guide at the tip. a release pedal which has a pedal lever at the top and is attached to a shaft installed horizontally on the jack body, and whose lower end is pivotally connected to the jack body and which is pushed out by the movement of the pedal lever when the pedal is depressed. The engaging portion is characterized in that it includes a rod that transitions from the locking groove to the releasing groove.

An embodiment of the present invention will be described below with reference to the drawings.

The drawings show an embodiment of the present invention, with FIG. 1 being a needle perspective view and FIG. 2 being a sectional side view.

In the drawing, 1 is the garage jack body, 2
is the jack handle, 3 is the guide, 4 is the bolt,
5 is rod, 6 is pedal lever, 7 is pedal, 8
is the lock pin, 9 is the shaft on the pedal side, 10 is the occluded groove for locking, 11 is the long groove on the release side, 1
2 is a handle side shaft.

That is, a jack handle is rotatably attached to the garage jack main body 1 by a shaft 12. A pipe and a steel plate are welded to the lower part of the handle 2, and a guide 3 is fixed with bolts 4, and the handle 2 rotates within the pipe of the guide 3 to open and close the hydraulic valve. The guide 3 also has an occluded groove 10 for locking and a long groove 11 for releasing, which is connected to this groove 10. In the link mechanism, a pedal is attached to a shaft 9 installed horizontally on the bracket of the main body 1, and when the pedal 7 is stepped on, a lever 6 attached to the tip of the pedal 7 comes into contact with the rod 5, and the rod 5 is pushed out. Since the lower end of this rod 5 is pivotally connected to the bracket of the main body 1,
By pushing out the lever 6, the rod 5 moves into the guide 3.
There is a transition from the occluded circular groove 10 for locking to a long groove 11 on the release side. When operating the jack by tilting the handle 2 to the rear, the pedal 7 is depressed until it hits the lock pin 8 that serves as a stopper, and then the handle 2 is tilted to operate in the usual manner. While the handle 2 is in operation, the rod 5 repeatedly slides in the long groove 11 on the release side. After using the jack handle 2, as shown in the figure, the handle 2 can be turned vertically and locked.

In this way, the guide 3 is attached to the jack handle 2, and the locking groove 10 and the releasing groove 11 are installed.
With the rod 5 attached diagonally to the bracket of the main body 1, when the handle 2 is near the vertical position, it is always moved into the locking groove 10 by the weight of the rod 5, so even if the handle 2 is about to fall over, the lock will not be locked. You can definitely do it. Moreover, the release method is a pedal type, which has a light action and is simple and easy to perform. The attachment portion of the rod 5 and the attachment portion of the pedal 7 are designed to reduce friction as much as possible, so that the rod 5 and the pedal 7 return by their own weight.

Therefore, according to the present invention, since the jack handle has a combination of a rod and a guide groove,
The structure is simple, the lock can be reliably locked automatically, and the lock can be released using a foot pedal, so the operation is extremely simple.
