Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a push button support structure formed at the corner of an equipment frame, specifically for a vacuum cleaner stop switch and an electric cord winding mechanism. etc., intercom push buttons, etc.

(b) Prior art The pushbuttons installed in conventional equipment have a structure in which the pushbutton, such as a switch, protrudes from a through hole formed in the equipment frame, and when the pushbutton is made larger, the upper surface of the equipment frame is pushed. Since it was covered by a button, its size was limited, and it could only be operated by pressing it directly down. Improvements on these points include devices in which a keyboard-like switch such as a piano is installed extending from the top surface of the equipment frame to one side; It wasn't.

(c) Purpose of the invention The purpose of this invention is to provide a support structure that allows a push button to be attached to a corner of an equipment frame with a simple structure.

(d) Structure of the invention The present invention includes a recess formed in a corner of the device frame, in which an operating part such as a switch is located, extending from the top surface to both sides, and a push button covering the recess. A pivot support is formed in the upper part of the inner surface of one side, a guide part is formed in the lower edge of the recess facing the inner surface of the one side, and the push button includes a support part that is pivoted on the pivot support. , and a holding portion guided by the guide portion.

(e) Example 1 Using the vacuum cleaner shown in FIGS. 1 to 6 as an example
EXAMPLE The present invention will be explained based on a second example shown in FIGS. 7 to 9.

A first example will be explained.

The vacuum cleaner 1 consists of a dust collection case 2 having a suction pipe (not shown) attached to its front end, and a blower case 3 detachably attached to the rear of the dust collection case 2 using a clamp mechanism. A dust collection filter is installed in the dust collection case 2, and an insertion part 4 for installing a suction pipe is formed at the lower front end of the dust collection case 2,
A handle 5 is formed at the upper part of the front end. A bumper 6 is attached to the dust collecting case 2 from the lower half of the side surface to the lower surface. A swivel front wheel is attached to the lower front part of the dust collection case 2.

Recesses 7 are formed in the rear portions of both sides of the blower case 3, and rear wheels 8 are mounted within the recesses 7. The inside of the blower case 3 is divided into left and right sides by a partition wall 9, and a blower chamber 11 is equipped with an electric blower 10;
A cord reel chamber 14 is formed to house a cord reel 13 for winding up the electric cord 12.
The electric blower 10 is installed in the blower chamber 11 by interposing a support plate 15 and elastic packings 16 and 17.
Supported by The support plate 15 has partition ribs 18 and reinforcing ribs 19 formed in the blower chamber 11.
It is maintained at Air-permeable sound-absorbing materials 21, 21 are attached around the electric blower 15 and on the inner surface of the blower case 3 in which the exhaust hole 20 is formed. The cord reel 13 is supported between the partition wall 9 and the side wall of the blower case 3. The electric cord 12 is pulled out of the case through a cord pull-out hole 22 formed at one corner of the lower rear surface of the blower case 3. The cord pull-out hole 22 is recessed, and the recess is formed by utilizing the remaining space between the substantially rectangular inner surface of the blower case 3 and the circular cord reel 13.

A recess 23 is formed at both corners of the rear upper surface of the blower case 3, extending from the upper surface to both side surfaces.
An operating section of a switch for stopping the electric blower 10 is located in one of the recesses 23, and an operating section 24 for releasing the winding lock of the cord reel 13 is located in the other recess 23.
Push buttons 25, 25, which are substantially flush with the upper surface and both side surfaces of the blower case 3, are rotatably mounted in the recess 23. A shaft support 26 formed by a round insertion hole is formed at the upper part of the inner surface of one side of the recess 23. A guide portion 28 formed in the form of an arcuate groove is formed on the inner surface of the wall portion 27, which is the lower end portion of the recess 23, facing the inner surface of the one side of the recess 23. The arcuate groove forming the guide portion 28 is an arc whose center is centered on the horizontal line of the shaft support 26. Projections 29, 29 are formed on the rear surface of the blower case 3 on which the guide section 28 is formed, and the projections 29, 29 function as support legs when the vacuum cleaner 1 is supported in an upright position. Become. A support portion 30 is provided on a side edge of the push button 25 with respect to the shaft support 26, and is supported by the shaft support 26 and is formed of a cylindrical shaft. A holding portion 31 formed of a cylindrical shaft that is guided and held by the guide portion 28 is formed at the lower edge of the push button 25 facing the wall portion 27 . The operation section 24 is provided on the inner surface of the push button 25.
An operating piece 32 is provided in a protruding manner to abut the operating member 24 and press the operating section 24 in conjunction with the pressing of the push button 25. When the push button 25 is pressed by an external force, the push button 25 moves around a horizontal line passing through the support part 30.
In other words, the rotation is performed on the assumption that there is also a support at the edge of the push button 25 opposite to the support 30. The push button 25 returns to the state before being pressed by the return force of the operating section 24. The holding portion 31 is in contact with the inner surface of the wall portion 27 of the recess 23, thereby preventing the push button 25 from coming off from the recess 23. Further, the holding portion 31 is guided by the guide portion 28 to allow the push button 25 to rotate without rattling. The push button 25 is attached to the recess 23 by utilizing elastic deformation of the push button 25.

A second example will be explained. Note that the same structural parts as in the first embodiment are designated by the same names and numerals, and the explanation thereof will be omitted. Further, the actions of the push buttons are also omitted because they operate in the same way.

A shaft support 40 formed of a cylindrical shaft is provided at the upper part of the inner surface of one side of the recess 23 . The recess 23
A guide portion 41 formed of a cylindrical shaft is formed on the inner surface of the wall portion 27. A support portion 42 formed by a circular insertion hole is formed at the side edge of the push button 25 relative to the shaft support 40. The wall portion 27
At the lower edge of the push button 25, a holding part 43 formed by an arc-shaped hole is formed to be guided and held by the guide part 41.

In addition, in this proposal, the shaft support, the guide part, the support part, and the holding part are not limited to the first and second embodiments, and various combinations such as a hole and a shaft, a groove and a shaft, etc. are possible. .

(f) Effects of the invention This invention provides a push button at the corner of the equipment frame, which makes the push button larger, improves operability, and provides stability with a simple structure despite being supported on one side. It has the advantage of being able to be installed in such a way that it operates properly.
