Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clamp device used to detachably connect two members of a vacuum cleaner or the like.

Conventionally, this type of clamp device has a push-button type clamp with an engaging hook that is attached to one member, and it is fixed with screws using separate parts such as a clamp holder, so the number of parts is large and installation work is difficult. It's bad and the cost is high.

The present invention overcomes the drawbacks of the prior art by integrally forming a portion of the clamp holder on one of the two members that are connected to each other.

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

1.2 are mutually independent synthetic resin molded members, and one member lK is attached with a push button type clamp 3.

An engagement hook 5 is formed at the base of the clamp 3 and engages with the receiving portion 4 of the other member 2.

The outer wall 6 of the member 1 is provided with a tunnel-shaped insertion portion 7 through which the main portion of the clamp 3 is inserted.

The head of the clamp 3 protrudes outward from the tunnel-shaped insertion portion 7, and the degree of protrusion is set to be equal to or greater than the disengagement stroke of the hook 5.

Reference numeral 8 denotes a support wall formed inside the outer wall 6 with a space therebetween.

A compression coil spring 10 protruding from a hollow storage portion 9 of the clamp 3 is in contact with the support wall 8, and constantly biases the clamp 3 in the right direction in the figure.

The distance between the support wall 8 and the opening end of the tunnel-shaped insertion portion 7 is
The height of the clamp 3 is set to be greater than the length in the reciprocating stroke direction.

If the compression coil spring 10 has a structure that protrudes from the clamp 3 even at maximum compression, the end face of the spring and the clamp 3 at that time
The distance from the top end of the clamp is the height of the clamp.

Further, a small convex portion 11 is formed on the support wall 8 for positioning the compression coil spring 10 after it is attached.

The relationship between the concave and convex portions may be reversed, and a shallow recess for receiving the end of the compression coil spring 10 may be formed.

Further, the back side of the support wall 8 has a recess 12 into which a finger is inserted.

Next, the effect will be explained.

FIG. 1 shows a state in which members 1 and 2 are connected by a clamp 3. As shown in FIG.

Next, as shown in Fig. 2, when you place your thumb on the head of the clamp 3 and insert your remaining finger into the recess 12, applying force to your finger, the clamp 3 will move inwards against the elastic force of the spring 10. The hook 5 is removed from the receiving part 4 of the member 2.

This makes it possible to separate the members 1 and 2 in the vertical direction as shown in the figure.

The other ends of both members 1 and 2 are engaged and disengaged by appropriate means.

By the way, when this clamp 3 is pushed further in with something like a thin rod, the base of the clamp 3 finally touches the support wall 8.
The head comes out from the inner end of the tunnel-shaped insertion part 7.

FIG. 3 shows this state. 11. By pulling up the clamp 3 as shown in FIG. 4, the clamp 3 can be removed from the member 1.

The clamp 3 can be attached by performing this procedure in reverse.

Clamp 3 so that the convex part 11 does not get in the way of attachment and detachment.
A notch 13 through which the convex portion 11 passes is formed in the side wall.

As described above, in the present invention, a clamp having an engaging hook is attached to one member to be mutually coupled, and a receiving portion for the engaging hook is provided to the other member, and the outer wall of one member is provided with a clamp having an engaging hook. A tunnel-like insertion part is provided to allow the clamp head to protrude to the outside to the extent necessary for the release stroke, and a support wall is provided closer to the outer wall to support the compression coil spring protruding from the hollow storage part of the clamp. Since the distance between this and the opening end of the tunnel-shaped insertion portion is set to be greater than the length of the clamp in the stroke direction, the disengagement stroke is far exceeded, and the clamp head completely reaches the opening end of the insertion portion. The clamp can be removed by pushing the clamp inward with the 1 step and then sliding it to the side, and vice versa.
A clamp can be attached to it, and the clamp can be attached without using screws or the like.

An uneven part for positioning the compression coil spring is formed on the broken support wall surface, and the spring needs to go over the uneven part to remove the clamp, so even if the clamp is pushed deep, the head It will not be immediately displaced from the insertion portion, and unexpected disassembly due to carelessness can be prevented.

Therefore, the number of parts to be attached to the clamp device is small, and assembly and disassembly operations can be easily performed.
