Description

[Detailed description of the invention] This invention relates to a clamp device that removably connects the main body of a vacuum cleaner, etc. to the top opening of a storage case, and the clamp hook and the The purpose is to reduce the number of parts, improve assembly workability, and reduce costs by fixing the hook cover member.

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

Reference numeral 1 denotes a vacuum cleaner main body, and 2 a parts storage case for storing auxiliary parts used in the vacuum cleaner main body 1, such as a floor suction tool, an extension pipe, and a flexible hose.

A stepped portion 4 that fits into the opening edge 3 of the parts storage case 2 is provided on the lower circumferential side of the vacuum cleaner body 1, and a locking protrusion provided at the front and rear of the opening edge 3 is provided below the stepped portion. Engagement recesses 7 and 8 are formed for engagement with the clamp device 5 and the clamp device 6, respectively.

The clamping device 6 has a notch hole 9 provided in the opening edge 3 of the component storage case 2 so as to open the upper surface thereof, and an upper surface opening formed to protrude inside the storage case 2 opposite to the notch hole. a clamp hook 12 located in the notch hole 9 and rotatably supported between the inner surface of the bag part 10 via a coil spring 11; and a pair of clamp hooks 12 provided in the bag part 10. a cover member 15 that clamps the shaft portions 14, 14 of the clamp hook 12 together with the supporting ribs 13, 13;
It is composed of

The clamp hook 12 has a claw portion 16 on the inner surface above the shaft portions 14 on both sides, which engages with the engagement recess 8 of the cleaner body 1.
and a support boss 17 for the coil spring 11 are integrally formed on the lower inner surface.

Further, the shaft portions 14, 14 of the clamp hook 12 are located in semicircular arc grooves 18, 18 provided at the upper ends of the support ribs 13, 13, and are held between the inner surface of the earthen wall of the cover member 15, and are held in place by the elastic force of the coil spring 11. The cover member 15 is biased counterclockwise due to its nature, and its rotation is normally restricted by the end face of the earth wall of the cover member 15.

Further, the cover member 15 has a pair of locking holes 21 which are pressed by guide ribs 19, 19 provided on the bag portion 10 and engage with protrusions 20, 20 provided on the inner surface of the storage case 2. It forms a leg 22.22.

Next, the assembly of the clamp device having the above configuration will be explained.

First, one end of the coil spring 11 is inserted into the support boss 17, and while the coil spring 11 is compressed between it and the inner surface of the bag portion 10, the shaft portion 14.14 of the clamp hook 12 is inserted into the semicircular arc shape of the support ribs 13, 13. When the cover member 15 is inserted into the grooves 18, 18 and then inserted along the guide ribs 19, 19 of the bag portion 10, the mounting legs 22, 22 are engaged and locked, as shown in FIG. Assembly is completed as shown.

The shaft portions 14, 14 of the clamp hook 12 and the cover member 15 are attached in the state shown in FIG. 4A and the opening, respectively.

In order to remove the vacuum cleaner main body 1 which is fitted and locked to the upper opening edge 3 of the parts storage case 2 by such a clamp device, when the lower part of the clamp hook 12 is pushed inward, the clamp hook 12 is moved by the elastic force of the coil spring 11. against the shaft portion 14.
14 in the clockwise direction, and the claw portion 16 is disengaged from the engagement recess 8 of the vacuum cleaner main body 1.

If the cleaner main body 1 is lifted upward in this state, the engagement of the protrusions and recesses on the front part will naturally come off, allowing the cleaner to be completely separated from the parts storage case 2.

In addition, when fitting and locking the vacuum cleaner main body 1 to the parts storage case 2, first engage the front engagement recess 7 of the vacuum cleaner main body 1 with the locking protrusion 5 of the storage case 2, and in this state When the vacuum cleaner main body 1 is lowered, the inclined surface 23 at the bottom of the main body comes into contact with the claw portion 16 of the clamp hook 12, so that the clamp hook 12 is temporarily forced outward against the elastic force of the coil spring 11. After the movement, the claw portion 16 engages with the engagement recess 8 at the rear of the main body.

As described above, the storage case clamping device according to the present invention includes a notch hole provided at the opening edge of the storage case through which the vacuum cleaner body etc. can be attached and removed, and an upper opening formed overhanging inside the storage case opposite to the notch hole. A bag portion, a clamp hook located in the notch hole and rotatably supported by the bag portion via a spring member, and a cover member that clamps the shaft portion of the clamp hook together with the support rib of the bag portion. Since the mounting portion of the cover member is engaged with the locking portion of the bag portion through elastic deformation, the clamp hook and the cover member can be attached at the same time without using fixing screws. It can be fixed, and has practical beneficial effects such as improved assembly workability due to the reduction of parts, lower cost, and improved appearance.
