Description

TECHNICAL FIELD The present invention relates to a vacuum cleaner for cleaning the interior of an automobile installed in a gasoline filling station or the like.

[Conventional technology]

As a service unit for automobiles, a vacuum cleaner that cleans the interior of automobiles, an air replenisher that replenishes tire air, an air blow device that blows off dust that has adhered to the engine room and air filters, and a washing device that cleans the vehicle body. There is one in which service devices such as the above are integrally incorporated in one unit case, and the suction hose, the air filling hose and the like of these service devices are suspended outside the unit case.

By the way, conventionally, for example, a flexible hose made of a material such as vinyl is generally used as a suction hose of a vacuum cleaner, but a hard pipe such as an aluminum pipe is used in an intermediate portion of the flexible hose, and a case of this hard pipe is used. There is a hose that moves vertically and horizontally with the side as a fulcrum so that the hose has directionality and is easy to handle.

[Problems to be solved by the invention]

However, with such a structure, it is difficult to obtain sufficient directionality because the vicinity of the root of the hose is oriented to some extent, and it can be said that it has been sufficiently solved in terms of ease of handling. There wasn't.

Also, one end of the rod-shaped balance rod is used as a hose support part, and after passing the middle part of the flexible hose here, it is hung,
A balancer is provided at the other end of the balance rod, and the weight of this balancer always lifts the end of the balance rod on the side opposite to the side on which the balancer is provided, that is, the hose support part, and the hose is not used. Occasionally, since the middle part of the hose is lifted in the air, the hose is not dragged to the floor and is prevented from being damaged or polluted by Japanese Utility Model Publication No. 47-35656.

However, in Japanese Utility Model Publication No. 47-35656, the lifting force on the side where the hose support is provided at the end of the balance rod is determined by the distance from the fulcrum of the balancer and the weight of the balance rod. There is no turning force when the balance rod is upright. It becomes the largest in the horizontal state and it is difficult to obtain uniform turning power. Moreover, since the weight of the entire apparatus is heavy, it cannot be attached to the head of the service unit case.

The object of the present invention is to eliminate the inconvenience of the above-mentioned conventional example, and because it is light in weight, it can be attached to the head of the service unit case, and the hose can be provided with sufficient and smooth directionality, which makes it easy to handle and work. It is an object of the present invention to provide a vacuum cleaner that can improve efficiency, has a simple structure, is compact, and has a reliable strength for cleaning the interior of an automobile.

[Means for solving problems]

Mounted so that the tip of the shift arm stands up, the frame and the rear end of the shift arm are connected by a spring, and a sliding arm of a rigid pipe is attached to the tip of the shift arm, and the suction hose is attached. Connected to the rear end of the swinging arm, connecting a separate suction hose to the tip of the swinging arm, attaching a nozzle to the end of the suction hose, and further forming a plurality of pin insertion holes in the frame body, Rotate the shift arm into one of the mounting holes. It is an summarized in that the insertion of the stopper pin for restricting the range.

[Action]

According to the present invention, since the rear end of the shift arm is pulled downward by the pulling force of the spring when the vacuum cleaner is not used, the shift arm is in a state in which the tip is lifted upward about the axis, The upper limit of the lifting angle can be determined by appropriately selecting the stopper pin from a plurality of mounting holes formed in the frame body. Further, the swinging arm supported by the shift arm can also maintain the state in which the tip end is lifted upward.

Also, since the swivel joint rotates horizontally in the direction in which the suction hose is pulled, and the shift arm moves up and down about the axis, the sliding arm moves above and below the case in the vertical and horizontal directions, and the suction hose is suspended. The dots can move smoothly near the car.

Further, since the swivel joint is provided in the case around the leading portion of the suction hose from the upper surface of the hose, the suction hose can be secured by the swivel joint.

Further, by using the swinging arm as a tubular body and utilizing this as a suction path, the members can be shared.
