Abstract

PURPOSE:To attain washing of a four-wheel-drive vehicle by providing carriages, onto which front wheels of an automobile are mounted, movably in a washing position in the lower of a car washer main unit and rollers for supporting the front wheel in this carriage, in a car washing device in which a portal frame and the carriage are moved in the reverse direction to each other. CONSTITUTION:A pair of right and left carriages 4 for moving an automobile are arranged in a car washing position, formed between a pair of right and left rails 3, in the lower of a portal car washer 1 in which rotary brushes are mounted respectively to both right and left side surfaces and roof surface of a portal frame. These carriages are constituted such that a pair of front and rear rollers 5 are rotatably mounted onto a carriage frame 4a in a space a little narrower than the diameter of a wheel B of the automobile, while an on-riding bed 6 of the front wheel B is turnably pivotally mounted further behind the rear roller 5. These carriages 4 are longitudinally moved in an opposite direction to the car washer 1 through wheels 9 on rails 8 by a chain 14 turned by a chain driving gear 10 having a motor.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a gate-type car wash apparatus for washing automobiles.

[Conventional technology]

Conventionally, the same type of car washing device was developed in Utility Model Application No. 57-17415.
There is a shortened gate-type car wash device, such as No. 6, in which a gate-shaped frame and a truck are moved in opposite directions. However, when the truck moves, the front wheels of a vehicle such as a four-wheel drive vehicle whose front wheels rotate in conjunction with the rotation of the rear wheels tend to fall off the truck.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the disadvantages of the conventional example and provide a shortened gate-type car wash device that can wash cars without any trouble, even in cars where the front wheels rotate in conjunction with the rear wheels, such as a four-wheel drive car.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a dolly for placing the front wheels of a car at a car wash position formed below the main body of a gate-type car wash machine so as to be movable in a direction opposite to the main body of the car wash machine, and the dolly is provided with a front wheel support. The gist of the invention is that it has a roller for use.

[Effect]

According to the present invention, when the trolley moves, the rear wheels of the vehicle are rotated by being pulled by the trolley, and in this case, for a four-wheel drive vehicle, the front wheels also rotate in conjunction with the rotation of the rear wheels. Since it is supported by rollers, the rotation of the front wheels is absorbed by the rotation of these rollers, so the front wheels do not fall off the trolley. In addition, in the case of a front-wheel drive vehicle, the front wheels would spin and the vehicle would not be able to get off the trolley, so the rollers could be fixed with pins.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a plan view showing an embodiment of the shortened gate type car wash device of the present invention, and Fig. 2 is a partially cutaway side view of the same. Rotating brushes 2 are attached to the left and right sides and the ceiling inside. Also, 3 in the diagram
indicates a rail for moving the gate-type car wash machine 1.

A cart 4 for moving automobiles is disposed at a car washing position formed between the rails 3 and 3 below the gate-type car wash machine 1. This trolley 4 consists of a pair of left and right wheels, which are placed on the front and back of a trolley frame 4a, and have a pair of rollers 5.5 pivoted at an interval slightly narrower than the diameter of the vehicle's wheels B. Furthermore, at the rear, a platform 6 for the front wheels B is rotatably provided obliquely.

The platform 6 is provided with a weight 7a and a stopper 7b on the opposite side of the tip of the step board 6a so that the tip of the step board 6a does not touch the ground at all times.

Reference numeral 8 in the figure indicates a rail for moving the truck laid parallel to the rail 3 between the rails 3, and wheels 9 provided at the lower part of the truck frame 4a engage with this rail 8.8.

As a moving mechanism for the trolley 4, a motor 11 as a chain drive device 10 and a gear 12 driven by the GL motor 11 are provided slightly outside one end of the rails 8, 8 between the rails 8. A gear 13 was provided outside the other end of the rails 8, 8, and both ends of a chain 14, which was stretched around both gears 12, 13, were connected to the carts 4, 4 via a connecting device 15, respectively.

Also, as shown in Figure 4, there are two pins on the side of the truck frame.
0 was provided and inserted into the hole 21 so that the roller could not be rotated. Note that the pin 2o is held in the position at the time of insertion and removal by a click mechanism.

Next, usage and operation will be explained.

To wash car A, gate type car wash machine 1 and trolleys 4, 4 are used.
The vehicle moves forward toward the gate-type car washer 1 from the rear extension line of the vehicle, places the front wheel B on the footboard 6a of the trolley 4, and then advances further and places it between the front and rear pairs of rollers 5.5. At this time, step vi
6a is in a state where the tip is floating on the ground due to the weight 7a before the front wheel B gets on it, but when the front wheel gets on it, the tip touches the ground, and when the front wheel moves to 0-sea 5.5, the weight 7a floats on the ground. 1a causes the tip to float above the ground again.

If the front wheel B is supported by the rollers 5.5 in this way, when driven in this state, the gate-type car washer 1 will move along the rails 3, 3 in the direction of the arrow in FIG. 3, that is, to the left. At the same time, the motor 11 of the drive device 1o of the chain 14 rotates, and the cart 4.4 similarly moves in the direction of the arrow on the right in FIG.

As a result, the front wheels B supported on the bogies 4, 4 move to the right together with the bogies 4, 4, and the entire body of the automobile is pulled by the bogies 4, 4 and moves to the right.

At this time, by keeping the gear of the car in neutral and free, the rear wheels rotate freely as the truck 4.4, that is, the car body moves. If the car is a four-wheel drive vehicle, the rotation of the rear wheels will also rotate the front wheels B, but the rotation of the front wheels B will be transmitted to the rollers 5.5, causing the rollers 5, 5 to rotate. is absorbed here.

Therefore, even if the front wheel B rotates, it will not rotate idly and the front wheel will move forward in front of the carts 4, 4 and will not fall off from above the cart 4.4.

In the case of a front-wheel drive vehicle, the rollers are fixed by inserting the pin 20 into the hole 21, so that when getting off the vehicle, the front wheels will not spin and make it impossible to get off the vehicle.

〔Effect of the invention〕

As described above, the shortened gate type car wash device of the present invention has the front wheels supported on the trolley supported by rollers when moving the car, so it can be moved like a four-wheel drive car. Even if the front wheels rotate in conjunction with the rear wheels, it is possible to prevent the front wheels from falling off the cart.

Additionally, by making the rollers non-rotatable, it can be used in front-wheel drive vehicles without any problems.
