Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a vacuum cleaner having a rotatable handle.

(B) Prior Art A vacuum cleaner having a rotatable handle is disclosed in, for example, Japanese Utility Model Application Publication No. 174555/1983. As shown in FIG. 6, this conventional example has a main case having an upwardly open dust collection chamber at the front and a motor chamber at the rear, and a lid 50 covering the dust collection chamber and the motor chamber, and an upper case. 51, a handle 52 is provided on the upper surface of the lid 50, the rotation axes of the lid 50 and the handle 52 are coaxial, and a lid rotation axis 53 is formed in the upper case. There is. However, the handle 52 of this conventional example is pivotally supported by the lid 50, and the lid 50 is further supported by the upper case 51.
Since the lid 50 is pivoted on the lid rotation shaft 53 and the amount of hooking of the lid 50 on the lid rotation shaft 53 is small, when an impact force is applied to the handle 52, the lid 50 is bent and the lid rotation shaft 53 is pivoted. There is a disadvantage that the handle 52 and the lid 50 come off from the upper case 51.

(c) Problems to be solved by the invention The invention has a hand-held handle and a lid for the dust collection chamber that are rotatably supported on the upper case, thereby improving the operability of the handle and making it easier to open and close the lid. It is an object of the present invention to provide a vacuum cleaner that can be easily operated and used.

(d) Means for solving the problem The vacuum cleaner of the present invention includes a lower case having a dust collection chamber in the front part, an upper case covering the rear part of the lower case to form an equipment storage chamber. The dust collecting chamber has 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, and a handle rotation hole is bored in the front part of the upper case. A handle support wall and a lid support wall coaxially positioned in the handle rotation hole and having a lid rotation hole are arranged side by side, and the lid rotation shaft is loosely inserted into the lid rotation hole. , the pivot portion of the handle covers the lid rotation hole and the lid rotation shaft, and the handle rotation shaft formed in the pivot portion is loosely inserted into the handle rotation hole. .

(E) Function The lid of the dust collection chamber is rotatably supported by the lid support wall of the upper case, and the handle is rotatably supported by the handle support wall of the upper case. The pivot portion of the handle covers the lid rotation hole and the lid rotation shaft, and serves to prevent the pivot portion of the lid from coming off, and the pivot portion itself also fits between the lid support wall and the handle support wall. This prevents the handle and lid from falling off from the upper case.

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

Reference numeral 1 denotes 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) and a cord are installed at the bottom of the upper case 3. It constitutes an equipment storage chamber 4 that houses a reel device (not shown),
Furthermore, a dust collection chamber 6 having an upper opening 5 for discarding dust is formed in the front half of the lower case 2. 7 is a hose connection port provided at the front of the lower case 2 so as to communicate with the dust collection chamber 6; 8 is a paper bag filter mounting member; this mounting member 8 connects the mouth of the paper bag filter 9 to the hose connection port 7; It is installed in communication. The upper part of the upper case 3 is covered with an upper case cover 10.

Reference numeral 11 denotes a lid body that covers the upper opening 5 of the dust collection chamber 6 in a freely openable and closable manner, and 12 denotes a handheld handle rotatably stored in a handle storage recess 13 recessed in the upper surface portion of the lid body 11. The lid body 11 and the handheld handle 12 are coaxially and rotatably supported on the front part of the upper case 3 by the following pivot structure. That is, 14, 14 is a pair of left and right handle shaft support protrusions that protrude forward from the central part of the front part of the upper case 3, and are provided upwardly on the left and right sides of this protrusion, and the outer surfaces of the respective handles are attached to the handlebars. Rotation hole 15,1
5 are provided as handle support walls 16, 16. The handle rotation hole 15 has an upper opening end 1 thereof.
5a is slightly retracted inward from the lower opening end 15b. Further, reference numerals 17, 17 refer to a pair of left and right lids arranged in parallel with each other with a space between them and the handle shaft supporting projections 14, 14 on the outer side of the handle shaft supporting projections 14, 14 of the front protruding portion of the upper case 3. The lid body support wall 1
7, 17 are provided with lid rotation holes 18, 18 positioned coaxially with the handle rotation holes 15, 15. The pivot portion at the rear of the lid body 11 is stepped downward one step and has pivot ribs 19, 19 raised up to form handle fitting grooves 20, 20.
, and a lid rotation shaft 2 is formed on the ribs 19, 19.
1 and 21 are installed protrudingly. A pair of U-shaped pivot parts 24, 24 having an outer piece 22 and an inner piece 23 are formed at both left and right ends of the handle 12, and an inward handle rotation shaft 25 is formed on the outer surface of the inner piece 23. It is installed protrudingly. Then, by pushing the lid 11 from above using the elasticity of the lid 11, the lid rotation shaft 21 is pushed into the lid rotation hole 18 of the lid support wall 17 of the upper case 3 from above, and the lid 11 is pushed in from above. (see FIG. 5A), and then attach the U-shaped pivot portion 24 of the handle 12 to the lid support wall 17 and the lid 11.
Push the handle rotation shaft 12 from above into the handle rotation hole 15 of the handle support wall 16 of the upper case 3 so as to cover the shaft support rib 19 from above (see FIG. The case cover 10 is inserted from above and the lid 11 and handle 12 are rotatably attached to the front part of the upper case 3 (see FIG. 1). Then, the outer piece 22 of the U-shaped pivot portion 24 of the handle 12 enters the handle fitting groove 20 of the lid body 11,
The inner piece 23 is attached to the handle support wall 16 of the upper case 3.
By entering the gap between the handle 12 and the lid support wall 17, the handle 12 is prevented from coming off from the upper case 3, and the pivot portion 24 covers the lid rotation hole 18 and the lid rotation shaft 21 to prevent the handle 12 from coming off from the upper case 3. It prevents the 11 shaft parts from falling out.

(g) Effects of the invention According to this invention, a lid support wall and a handle support wall are installed in parallel at the front of the upper case, the lid of the dust collection chamber is placed on the lid support wall, and the handle is placed on the handle support wall. Since the pivot parts of the handle are independently rotatably supported, the lid and the handle can be securely attached to the upper case. Moreover, the pivot part of the handle prevents the pivot part of the lid body from coming off, and the pivot part itself also fits between the lid body support wall and the handle support wall to prevent it from coming off, and no impact force is applied to the handle or the lid body. It is possible to obtain a vacuum cleaner that does not come off from the upper case even when the load is applied, improves the operability of the handle, and makes it easy to use by making it possible to easily open and close the lid.
