DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a vacuum cleaner having a rotatable handle.

(B) Prior Art A vacuum cleaner having a rotatable handle was proposed by the applicant in Utility Model Application No. 62-39507, for example. This prior art is shown in Figures 4 and 5.
As shown in the figure, the lower case 5 has an upwardly open dust collection chamber at the front and an electric blower chamber at the rear.
1, a lid 52 and an upper case 53 that cover the dust collection chamber and the electric blower chamber are disposed, and the lid 52
A handle 54 is provided on the top surface of the upper case 5.
3, the rotation hole 55 of the lid 52 and the handle 54
A rotation hole 56 is coaxially provided, and a lid rotation shaft 57 provided on the lid 52 and a handle rotation shaft 58 provided on the handle 54 are connected to the two rotation holes 55, 5.
6 is loosely inserted.

However, in this prior art, since the lid rotation shaft 57 and the handle rotation shaft 58 are fitted into the two rotation holes 55 and 56 from the same direction, they are fitted into the case 53 in the same direction. When an impact force is applied in the same direction (arrow direction), the handle 5
4 and the lid 52 come off from the upper case 53.

(C) Problems to be Solved by the Invention The present invention has a hand-held handle and a lid of a dust collection chamber rotatably supported on an upper case, thereby improving the operability of the handle and making it easy to open and close the lid. To provide an easy-to-use electric vacuum cleaner that can be used in a variety of situations, and also prevents a handle and a lid from coming off from an upper case even when an impact force is applied.

(d) Means for Solving the Problems The vacuum cleaner of the present invention includes a lower case having a dust collection chamber, an upper case covering the rear part of the lower case to form an equipment storage chamber, and an upper surface of the upper case. a case cover disposed on the upper case; a lid body that covers the top opening of the dust collection chamber so as to be openable and closable; and a rotatable handle disposed on the top surface of the lid body; A pair of support walls protruding from the handle rotation axis and the lid rotation axis coaxially and facing each other are provided in parallel, and the lid rotation shaft is inserted into the lid rotation hole of the pivot portion of the lid. loosely inserting a moving shaft and arranging the pivot portion to face the handle rotation shaft, covering the pivot portion with the handle, loosely inserting the handle rotation shaft into the handle rotation hole of the handle, and further supporting one side. It is characterized in that the wall is supported by the case cover.

(E) Function The lid of the dust collection chamber is rotatably supported on the lid rotating shaft of the upper case, and the handle is rotatably supported on the handle rotating shaft of the upper case. The handle covers the pivot part of the lid body to prevent the pivot part from coming off, and since the lid rotation axis and the handle rotation axis face each other and one support wall is supported by the case cover, an impact force is applied. Both the handle and the lid will not come off from the upper case even if you put it on.

(F) Embodiments Hereinafter, the vacuum cleaner of the present invention will be described based on embodiments shown in the drawings.

(1) is a canister-type vacuum cleaner, in which an outer shell is formed from a lower case 2 and an upper case 3 that closes the upper half of the lower half of the lower case 2, and an electric blower (not shown) is installed at the bottom of the upper case 3. and a cord reel device (not shown).
Further, a dust collection chamber 5 having an upper opening for discarding dust is formed in the front half of the lower case 2, and a paper bag filter (not shown) is removably housed in the dust collection chamber 5. On the upper surface of the upper case 3, there are a case cover 6, switches 7, 7 for operating a cord reel, a power source, etc., and a small parts storage section 8.

Reference numeral 9 denotes a lid body which can open and close the top opening of the dust collection chamber 5, and has a hose connection port 10 which can be opened and closed by a shutter plate 10a. Further, reference numeral 11 denotes a hand-held handle rotatably stored in a handle storage recess 12 formed in the upper surface of the lid 9;
These lid body 9 and handle 11 are connected to the upper case 3.
It is coaxially and rotatably supported on the front part of the body using the following shaft support structure. That is, reference numerals 13 and 13 are bearing grooves formed symmetrically in the front part of the upper case 3, and the groove 13 is connected to a handle support wall 14 formed downward from the side surface of the upper case 3 and the handle support wall. 14 and a lid support wall 16 arranged in parallel with the handle support wall 14 via a bottom wall 15.
The handle rotation shaft 17 is connected to the lid support wall 16.
Lid rotation shafts 18 are provided coaxially and oppositely to each other and protrude inwardly. Reference numerals 19 and 19 denote pivot parts formed symmetrically on the lid body 9, and the pivot parts 19 have a downward U-shaped cross section and an inner flange 20.
and an outer flange 21, and the inner flange 20 has a lid rotation hole 22 into which the lid rotation shaft 18 is loosely inserted.
is installed. The left and right ends of the handle 11 have an outer piece 23 and an inner piece 24, respectively, and have a downward U-shaped cross section that covers the pivot portion 19 of the lid 9 and enters the bearing groove 13, The outer piece 23 has the handle rotation shaft 17.
A handle rotation hole 25 is bored into which the handle is loosely inserted.
The pivot portion 19 of the lid body 9 has an inner flange portion 20.
By loosely inserting the lid rotation shaft 18 into the lid rotation hole 22, the lid rotation shaft 18 is reliably supported, and the outer flange 21
is opposed to the shaft tip of the handle rotation shaft 17, and the handle 11 has an inner piece 24 at its end loosely fitted between the lid support wall 16 and the inner flange 20, and an outer piece 23. The handle rotation shaft 17 is press-inserted from between the outer flange 21 and the handle rotation shaft 17, and the handle rotation shaft 17 is loosely inserted into the handle rotation hole 25 of the outer piece 23, so that the handle rotation shaft 17 is reliably supported. 6 is disposed on the upper case 3, so that the pressing piece 26 of the case cover 6 presses and supports the lid rotation shaft protruding surface 16a and the rear surface 16b of the lid support wall 16. This pressure support prevents the lid support wall 16 from bending, and the distance between the lid rotation shaft 18 and the handle rotation shaft 17 is always constant.

Therefore, the handle 11 covers the pivot part 19 of the lid body 9 to prevent the pivot part 19 from coming off, and further supports the handle 11 and the lid rotation shaft 18 which pivotally supports the pivot part 19 of the lid body 9. Since the handle rotation shaft 17 faces the lid support wall 16 and is supported by the pressing piece 26 of the case cover 6, even if an impact force is applied in the axial direction of the two rotation shafts 17 and 18, the The distance between the two rotating shafts 17 and 18 does not become large. Therefore, even if an impact force is applied to the handle 11, the lid 9, or the upper case 3, the lid rotation shaft 18 will not come out of the lid rotation hole 22, and the handle rotation shaft 17 will not slip out of the lid rotation hole 22. 25, and therefore neither the handle 11 nor the lid 9 will come off from the upper case 3 even if an impact force is applied.

(G) Effects of the Invention According to the present invention, a pair of support walls in which a handle rotation axis and a lid rotation axis are respectively bored are provided in the front part of the upper case, and a handle is attached to the handle rotation axis. Since the pivot portions of the lid of the dust collection chamber are independently rotatably supported on the lid rotating shaft, the handle and the lid can be reliably attached to the upper case. In addition, by covering the pivot part of the lid body, the handle prevents the pivot part from coming off, and by supporting one of the support walls with the case cover, even if an impact force is applied to the handle, lid body, or upper case, the upper case will not come off. To provide a vacuum cleaner which is easy to use by improving the operability of the handle and making it possible to easily open and close the lid without the handle or the lid coming off.
