Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for arranging tanks on a trolley detachably by one-touch operation.

[0002]

[Prior art]

 For example, in a device such as a vacuum cleaner, it is necessary to smoothly discharge the contents of a tank mounted on a cart. Conventional devices are divided into two types: tanks that are built into the trolley or tanks that are separable. The former is difficult to discharge, so the latter is better, but there is still a problem with the installation and removal of the tank. For example, the one that attaches to and detaches from the trolley with a fixed band or the one that attaches and detaches with screws is difficult to attach and detach, and the one that attaches and detaches with multiple latches is easy to operate, but it is necessary to hang or remove multiple places at the same time. May be difficult to handle.

[0003]

[Problems to be solved by the invention]

 The present invention has been made by paying attention to the above-mentioned point, and the problem thereof is that a tank can be attached and detached by one-touch operation.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention provides at least two hooks provided on a bogie so as to be hooked on the protrusions of the tanks, and a tank at a position opposite to the hooks. It is intended to provide a tank attaching / detaching device provided with a part of the tank and a one-touch operation piece detachably provided on a truck side.

[0005]

[Embodiment of the invention]

 The quick detaching device for tanks according to the present invention is a tank or similar (separable tanks) which can be separated from the cart by one-touch operation and can be detached from the cart. . Since it is a one-touch operation, two or more operations are not required at the same time, and attachment and detachment can be performed with one operation.

In order to fix a heavy object such as a tank on a trolley and allow the trolley to move stably, it is necessary to fix at least three points. Therefore, in the present invention, the tanks are hooked at at least two places on one side, and the detachable operation can be performed on the other side.

That is, the present invention has at least two hooks provided on the trolley so as to be hooked on the protrusions of the tanks. The protrusions of the tanks may be newly provided protrusions, but for example, in the case of tanks made of sheet metal processing, a crimped portion formed at the lower end can be used as the protrusion. In addition, for example, in the case of tanks having a flange-shaped portion, the flange-shaped portion can be used as a projection.

On the other hand, a one-touch operation piece is provided at the position on the opposite side of the hooking portion so as to be detachable from a part of the tanks and provided on the carriage side. Only one fixing bracket is required. The one-touch operation piece may be a member that can be attached and detached with a so-called one-touch operation. Such a one-touch operation piece may be a known one. In short, it is possible to mount and dismount tanks by performing a one-touch operation on the last (or first) one of several fixed points.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an embodiment in which the present invention is applied to a vacuum cleaner 10. The illustrated vacuum cleaner 10 includes a carriage 11, a cleaner body 12, and a suction nozzle 13. The storage part corresponds to the tanks 14 in the present invention.

The tanks 14 are formed by processing a metal plate into a cylindrical shape. The tanks 14 have, at the lower end, a tightening portion that connects a tank bottom plate and a body plate. Is used for the projection 16. The protrusions 16 of the tanks 14 are hooked on two hooks 17 provided on the carriage (see the dashed line in FIG. 3). At this time, the projecting portion 16 of the tanks 14 approaches the hooking portions 17, 17 from behind and above, enters under the hooking portions 17, 17 and is hooked by the projecting portion 16.

The hook 17 for this purpose is composed of headed bolts and nuts planted at both front corners of the bogie 11. The front plate 18 on which the bolts and nuts are implanted is a portion where the front end of the tanks 14 rides, and the rear end of the tanks 14 rides on the rear plate 19 of the cart 11 (see FIG. 2).

A one-touch operation piece 20 that is detachable from a part of the tanks 14 is provided on the bogie side at a position opposite to the hanging portions 17, 17. The one-touch operation piece 20 is attached to a handle 21 rising from the trolley 11 by providing a support 22 (FIGS. 4 and 5), and a spring piece 23 pulled by the one-touch operation piece 20 is provided on the tanks 14. The hook portion 24 is mechanically engaged with the hook portion 24 and is in a mounted state. For example, the one-touch operation piece 20 is attached to the support 22 by a shaft 25. When the one-touch operation piece 20 is pulled in a direction away from the tanks 14, the spring piece 23 is loosened from the hook portion 24, and when pressed in the opposite direction, the spring piece 23 is hooked. This is a state in which the part 24 is tightened, and may be a commercially available product. Reference numeral 26 denotes a lock member.

However, it is desirable that the one-touch operation piece 20 is disposed above the two hooks 17, 17 which are hooked on the protrusion 16. See FIG. When an external force acts such that the tanks 14 come out upward, the tanks 14 are fixed by the one-touch operation piece 20, so that the fixing using the reaction force from the hooks 17, 17 acting on the tanks 14 is effectively performed. It is possible.

Therefore, when the one-touch operation piece 20 is operated, the tanks 14 are latched at the two hook portions 17, 17, and at the same time, the tanks 14 are locked together with the one-touch operation piece 20 on the opposite side. It is fixed at three places and integrated with the cart 11. When the one-touch operation piece 20 is reversely operated, a part of the tanks 14 is disengaged from the one-touch operation piece mechanically, and the tanks 14 can be immediately moved. Removal is also very easy.

[0015]

[Effect of the invention]

 Since the present invention is constructed and operates as described above, only one one-touch operation piece is required, and the minimum number of hooks is two, so that a total of three places can be securely fixed. Yes, attaching tanks to the trolley, detaching the tanks from the trolley, and detaching the tanks from the trolley can be performed very easily by one-touch operation of the operation piece. As a result, workability can be significantly improved.
