Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gate-type car wash device, and in particular, the width of the frame body can be reduced to effectively use space.
This invention relates to a gate-type car wash device that can be extended in width to accommodate large vehicles such as foreign cars.

[Prior Art] As is well known, a gate-shaped car wash device includes a gate-shaped frame body that reciprocates on rails, and within the frame body there are rotating brushes disposed horizontally to mainly wash the roof of the car, and It is equipped with rotating brushes arranged vertically to wash both sides of the car, rotating brushes arranged vertically to mainly wash the bottom of the doors and around the tongue, and a shower nozzle that sprays washing water. The vehicle to be washed enters the gate-shaped car wash device, and the gate-shaped frame body is reciprocated while washing water is jetted from the shower nozzle and the rotary brush is rotated to wash the vehicle.

In such a gate type car wash device, the width of the gate frame body is constant, and if it is suitable for large vehicles, the width is unnecessarily wide, so it occupies a large space and requires extra space for installation. The ones that fit the bill were not very wide and did not take up much space, but they were not able to wash large cars, and as a result, they were losing customers.

Japanese Unexamined Patent Publication No. 54-82856 discloses a gate-type car washing device that is provided with a fixed arm and a swinging arm for folding. However, in this known technique, the gate-shaped frame itself cannot be adapted to the width of the car to be washed, since the space is used for other purposes after it is folded.

[Problems to be Solved] Accordingly, an object of the present invention is to provide a gate-type car wash device in which the width of the frame body can be adapted to the width of the automobile.

[Means for Solving the Problems] According to the present invention, a gate-type car wash device is provided in which a rotating brush is installed in a gate-shaped frame and the car is washed by jetting wash water from a shower nozzle and rotating the rotating brush. , the gate-shaped frame body is composed of two parts that are movable laterally, and at least one of the lower parts is provided with a groove that can be moved in the width direction with respect to a movable wheel that engages with the rail. The water pipe is provided with a lateral moving means for moving the frame body in the width direction, and an expanding and contracting means for making the water pipe correspond to the movement of the frame body in the width direction.

[Description of Functions and Effects] Therefore, the frames are usually spaced relatively narrowly apart from each other, and ordinary cars are washed. When washing a large vehicle such as a foreign car, the frames are moved in the width direction by the lateral moving means to widen the space between the frames. At this time, the frame moves, but the wheels remain engaged with the rails, and the frame moves along the groove. At the same time, the length of the water pipe in the width direction is adjusted by the expansion and contraction means.

Therefore, normal car washing work can be performed even on large vehicles.

By moving the frame of the gate-type car wash device in two parts in the width direction in this way, there is no need to prepare a device that is unnecessarily adapted to large vehicles, and space can also be used effectively.

[Preferred Embodiment] In carrying out the present invention, it is preferable that the lateral movement means use a motor, a screw rotated by the motor, and a nut screwed into the screw to change the distance between the frames.

Further, it is preferable to use bellows or the like as the means for expanding and contracting the water pipe.

[Embodiment] The drawings show a gate-type car wash apparatus according to an embodiment of the present invention, and FIG. 1 is a perspective view thereof. In FIG. Inside, there is a rotating brush 2A arranged horizontally that mainly cleans the roof of the car, a rotating brush 2B arranged vertically that mainly washes both sides of the car, and a rotating brush 2B that mainly washes the lower part of the door and around the tires. A rotating brush 2C arranged in the vertical direction and shower nozzles 4A to 4C arranged in the water pipe 3 that spray cleaning water (water or water mixed with detergent).
is provided. And this gate-shaped frame 1
is powered by a built-in electric drive (not shown).
It is designed to move back and forth on rails 5, 5.

Operation switches 6 are provided on the front of the frame 1, and by turning on these switches 6, the frame 1 moves back and forth on the rails 5, 5, and the rotating brushes 2A to 2C rotate. The pump 7 operates and sucks water from the water tank 8, and the hose 7A
is supplied to the water pipe, and the shower nozzles 4A to 4
It is designed to be injected from C.

Therefore, by placing a car (not shown) in this gate-type car wash device, the shower nozzle 4A
~Spray cleaning water from 4C, and also rotate brush 2A~
You can wash your car by rotating 2C.

Next, referring to FIG. 2 showing the internal structure of the gate-type car wash apparatus of the present invention, the gate-type frame 1 is composed of two parts, the first part 1A and the second part 1B, as described above. and each of those body covers 1a, 1
b overlaps in the upper horizontal part so as to be able to expand and contract;
A fixed wheel 1c that rolls on rails 5, 5, respectively, and a movable wheel 1E that moves along a groove 1D at the lower end of the main body cover 1b are provided at the lower end. 1st
In order to expand and contract the width of the frame body 1 of the second portions 1A and 1B, an expansion motor 12A is attached to the upper end of the first portion 1A, and a screw shaft 12B extends horizontally from the motor 12A. A nut 12C is fixed on part 1B, cooperating with the screw 12B. It is also possible to use other means instead of screws and nuts, such as linkages or hydraulic piston-cylinders.

The water pipe 3 equipped with a shower nozzle 4C that injects cleaning water is supported at both ends by support parts 3B, 3B fixed on each part of the frames 1A, 1B. In order to accommodate the expansion and contraction of the water pipes, telescopic pipes (bellows) 3A, 3A are provided between the support parts 3B, 3B and the central part of the water pipe.

The rotating brush 2A arranged horizontally has a large number of small brushes 10 mounted on a rotating shaft 11 by means such as keys so as to be non-rotatable with respect to the shaft but slidable in the axial direction. A spring 10B is interposed between the boss portions 10A fitted on the shaft 11 of each small brush 10, so that the small brushes 10 are moved toward and away from each other as the frame 1 expands and contracts. The shaft 11 is supported by holding arms 9B, 9B whose connecting areas are pivotally supported by the rotary shaft of the brush holding arm swing motor 9, which has both ends mounted on the body covers 1a, 1b, respectively, and the support portion 9A; As the swing motor 9 rotates, it swings around its axis and moves up and down along the hood, windshield, roof, etc. of the car. The shaft 11 is rotated by a suitable transmission 11B from a brush rotary motor 11A supported on the arm 9B.

Note that since the second portion 1B moves in the lateral direction, that is, in the width direction, the upper ends of the rotating shafts of the two rotating brushes 2B are vertically arranged and the upper ends of the rotating shafts of the two rotating brushes 2B are aligned with each of the portions 1A and 1B.
They are provided in each section so that they can be moved along rails (not shown).

When the gate-type car wash device of the present invention washes a car,
When the width of the frame body is set according to the width of the car by operating the operation switch 6, the telescopic motor 12A rotates normally according to the set width, and the screw shaft 12B and the nut 12
Due to the action of C, one side 1B of the gate-shaped frame 1 extends. At this time, the movable wheel 1E moves while being guided by the groove 1D, the rotating brush 2A is extended at equal intervals by the spring 10B, and the telescopic pipe 3A of the water pipe 3 is extended, so that the movement is performed smoothly. There is nothing wrong with washing the car. As the brush rotates, the nozzle 4A,
The car is washed by spraying washing water from 4B and 4C.
When the car wash is finished, the motor 12A rotates in reverse, and the gate-shaped frame 1 contracts to its original state. In this way, by minimizing the width of the gate frame when not in use, the space occupied by the car wash apparatus can be minimized.

[Effects of the Invention] As described above, according to the present invention, the following excellent effects are achieved.

(1) Regular car wash work can be performed on both small regular cars and large foreign cars.

(2) The space occupied can be minimized, allowing efficient use of space at gas stations, etc.

(3) There will be no problems with water supply work.
