Description

[Detailed Description of the Invention] A. Purpose of the Invention (1) Industrial Application Field The present invention can block the noise generated during the operation of the car wash machine and also prevent the splash of the washing spray. The present invention relates to a device for blocking noise and preventing splashes of washing in a car wash machine.

(2) Prior Art In the above device, a gate-type traveling frame equipped with a car-washing device is supported on a guide rail on an installation surface so that it can travel back and forth across a stopped vehicle, and the gate-type traveling frame is supported. On the back of the traveling frame, one end of a cover that can expand and contract along the traveling direction of the frame is fixed, and this cover blocks noise of car washing equipment and prevents splashes of washing spray. For example, the one that is done is
It is conventionally known as disclosed in Japanese Patent Publication No. 84.

(3) Problem to be Solved by the Invention In the above-mentioned conventional device, the other end of the cover is fixed on the installation surface so that it can be moved back and forth within a predetermined section. Since it is guided and supported by the above, when the movement stroke of the other end of the cover (the length of the predetermined section) is set to be long, it is necessary to enlarge the storage box in the front-rear direction. However, since the storage box faces the back of the gate-shaped traveling frame and is arranged to regulate the backward limit of the frame, the backward limit of the portal-shaped traveling frame becomes forward with the enlargement of the storage box. There is a problem that the main part of the car wash machine including the storage box and the cover body becomes relatively large in the front-rear direction in the unused state (storage standby state shown in FIG. 1).

Further, when the storage box is formed to be short in the front-rear direction, the above problem does not occur, but on the other hand, there is another problem as follows. That is, if the storage box is shortened in the front-rear direction, the movement stroke of the other end of the cover with respect to the storage box is shortened accordingly. It is necessary to secure a necessary traveling stroke, and there is a problem that the structure of the cover body is complicated and the size is increased to increase the cost.

The present invention has been proposed in view of the above, and an object of the present invention is to provide a noise blocking and washing splash scattering prevention device in a car washing machine, which does not have the above problems of the conventional device.

B. Configuration of the Invention (1) Means for Solving the Problems To achieve the above object, according to the present invention, a gate-type traveling frame equipped with a car-washing device straddles a parked vehicle and extends in front of and behind it. One end of a cover, which is supported by a guide rail on the installation surface so that it can reciprocate and is expandable and contractible along the traveling direction of the frame as the frame travels, is fixed to the back of the portal traveling frame. A noise blocking and washing splash scattering prevention device for a car washing machine, in which noise of the car-washing device is blocked by a cover body and splashes of washing powder are prevented, and the other end portion of the cover body is provided on the installation surface. Is movably supported within a predetermined section along the traveling direction of the gate type traveling frame, the predetermined section is set to be longer than the maximum contraction length of the cover, and further on the installation surface within the predetermined section. , The top of the cover A space is formed to allow the portal frame to enter when contracted.

(2) Operation According to the above configuration, the other end of the cover is movable within a predetermined section along the traveling direction of the gate type traveling frame, and the predetermined section is set longer than the maximum contraction length of the cover. Therefore, even if you do not extend the stretch stroke of the cover body,
The moving stroke of the other end of the cover (that is, the length of the predetermined section) can be set to be relatively long, and the running stroke of the gate-shaped running frame, which is the sum of both strokes, can be set to be sufficiently long.

In addition, since a space is formed on the installation surface within the predetermined section to allow the entrance of the portal traveling frame when the cover is contracted most, the predetermined section can be set to be relatively long as described above. The backward limit of the gate type traveling frame can be moved to the rear as much as possible, so that the main part of the car wash machine is miniaturized in the front-rear direction in its unused state (standby state for storage).

(3) Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In FIG. 1 and FIG. 2, a gate type traveling frame 1 of a mobile car washer is a pair of left and right laid on a ground E as an installation surface. It is supported on the guide rails 2, 2 so that it can travel back and forth via traveling wheels 3, and in the frame 1, a conventionally known cleaning brush device B, a drying nozzle device D, and other car-washing equipment are arranged. It is set up. Thus, when the gate-type traveling frame 1 travels back and forth across the vehicle V stopped between the left and right guide rails 2 and 2, the car-washing device is appropriately operated to operate the vehicle V. Various treatments such as brushing cleaning, rinsing and drying can be performed on the vehicle body surface, wheels and the like.

Within the reciprocating traveling locus of the gate-shaped traveling frame 1, a retractable cover C is attached to the guide rail 2 on the traveling frame 1.
The cover C is mounted so as to be able to extend and contract along the traveling direction, and the front end e ₁ of the cover C is fixed to the back surface of the portal traveling frame 1. A fence W is installed upright on the ground E near the rear end of the guide rail 2 to partition the boundary with the adjacent ground.

Next, the structure of the cover C will be described with reference to FIGS. The cover C is a flexible curtain 4 having a substantially U-shaped cross section so as to cover the upper surface and the left and right side surfaces of the vehicle V.
And a supporting device 5 that can foldably support the curtain 4 along the traveling direction of the gate type traveling frame 1, and the supporting device 5 can travel on the guide rails 2. A plurality of gate-shaped support frames 8 ₁ to 8 _{7 in} which the wheels 6 are pivotally supported on the lower ends of both sides and the ceiling of the curtain 4 is connected to the top via fasteners 7 such as strings, and also on the guide rails 2. the running wheels 9 which can travel and axially supported on both sides the lower end, a slightly low profile multiple portal auxiliary frame 10 ... and the supporting frame 8 _{1-8 7.}
The support frames 8 ₁ to 8 ₇ and the auxiliary frames 10 are alternately arranged along the guide rail 2 and are interlocked with each other via an interlocking mechanism L. Its interlocking mechanism L, each supporting frame 8 _{1-8 7} square pipe shaped sides lower 8a ₁ ~8a ₇ swingably pivoted has been next to the auxiliary frame two mutually parallel extending toward the 10 The horizontal links 11u, 11d and the vertical sliders 12 in the form of square pipes whose upper and lower ends are pivotally connected to the free ends of the horizontal links 11u, 11d are provided. Square pipe-shaped lower portions 10a on both sides of the frame 10 are slidably inserted, and the auxiliary frame 10 engages with the upper and lower ends of the vertical slider 12 to regulate upper and lower sliding limits thereof. , Lower stopper 13,14
Is fixed. Therefore, when the gate-type traveling frame 1 is moved forward (moved to the right in FIGS. 1 and 2) so as to separate the support frames 8 ₁ to 8 ₇ from each other, the horizontal links 11u and 11d are moved as shown by the solid line in FIG. , The auxiliary frames 10 are pushed downward through the vertical sliders 12 so that the traveling wheels 9 thereof come into contact with the guide rails 2, and the curtain 4 extends as shown in FIG. On the other hand, contrary to the above, the support frame 8 ₁ ~
When the gate type traveling frame 1 is moved backward (moved to the left in FIGS. 1 and 2) so as to bring the 8 ₇ closer to each other, the horizontal links 11u and 11d are moved through the vertical slider 12 as shown by the chain line in FIG. Each auxiliary frame 10
Is lifted to a height substantially the same as that of the support frames 8 ₁ to 8 _7, and its traveling wheels 9 are lifted from the guide rails 2. In this state, the ceiling portion of the curtain 4 is changed to the chain line in FIGS. 1 and 3. As shown, it folds compactly and contracts.

Meanwhile the support frame ₈₁ of the front end of the plurality of the supporting frame 8 _{1-8 7} has no running wheels are fastened to the back of the portal traveling frame 1 with a front end portion of Makutai 4. Also, especially at the rear end support frame
8 ₇ On both sides the bottom 8a ₇ of, on the inner side than the running wheels 6, the lower roller 15; and rotatably supported the 16 and 16 bracket
17 are fixedly attached, and the upper and lower rollers 15; 16,
16, by sandwiching each auxiliary rail 18 of the left and right laid on the ground E along the guide rail 2 from the vertical, running wheel 6 of the support frame 8 ₇ of the rear end prevents from floating from the guide rail 2 ing. More front and rear ends of each auxiliary rail 18, before it can engage the roller 15 to limit the movement range of the support frame 8 ₇ of the rear end, the rear stoppers 19 and 20 are fixed, thus by their stoppers 19 and 20 The support frame 8 _{7 at} the rear end, that is, the rear end e ₂ of the cover C is movable only in the defined predetermined section s.

Thus, as is apparent from the description of FIGS. 1 and 2, the predetermined section s is set so that the cover C is longer than the maximum contraction length s ′ (that is, the front-rear length in the folded state), Moreover, on the installation surface E within the predetermined section s, a space Sp is formed which allows the portal frame 1 to enter when the cover C is contracted most (when folded as shown in FIG. 1).

A support plate 21 is integrally joined to the inner surfaces of the intermediate portions on both sides of the curtain 4 along the direction of expansion and contraction, and the support plate 21 is made of a flexible plate material such as rubber. Further, a rigid inwardly convex curved plate 22 is fixed to the outer surfaces of both sides of the support frames 8 ₂ to 8 ₆ other than the support frames 8 ₁ and 8 _{7 at the} front and rear ends. The support plate 21 and the screen body 4 are joined to the outer side surface, that is, the concave curved surface, with bolts 23. As a result of the cooperation of the support plate 21 and the curved plate 22, when the curtain 4 is in the contracted state (FIG. 1), the intermediate portions on both sides of the support frame 8 ₁ to 8 ₇ and the auxiliary frame 10 are formed as shown in FIG. Can be securely folded in the outer position.

Further, the outer ends of flexible plate members 24 made of rubber or the like are fixed to the inner surfaces of the lower ends of both sides of the curtain 4 at positions facing the respective auxiliary frames 10, and the inner ends of the plate members 24 are attached to the respective auxiliary frames 10. It is fixed to the bottom edge. Since the plate member 24 has a predetermined waist strength, the lower ends of both sides of the curtain member 4 in the contracted state are the supporting frames 8 ₁ to 8 ₇ and the auxiliary frame 10 as shown in FIG. Can be securely folded at the outer position.

Next, the operation of the above embodiment will be described. FIG. 1 shows the stored state of the car wash machine. In this state, the cover C is in the most contracted state, and the rear end e ₂ thereof is held at a position close to the fence W. Support frame 8 at the rear end of the cover C
_The backward limit of 7 is restricted by the engagement of the roller 15 and the rear stopper 20.

From this state, when the vehicle V is stopped from entering the position shown by the chain line in FIG. 1 and then the gate-type traveling frame 1 is moved forward (to the right in the drawing) to wash the vehicle V, the frame 1
The cover C having the front end portion e ₁ fixed to the back surface also follows and moves forward. During this forward movement, the support frame 8 at the rear end of the cover C
_{Since the} forward limit of the roller ₇ is restricted by the engagement of the roller 15 and the front stopper 19, the cover C starts to expand after the restriction, and the forward movement of the portal frame 1 shown in FIG. 2 ends. At this point, the state of maximum extension is reached. As a result, the noise generated from the various devices B and D of the operating car wash machine is diffused in all directions through the rear opening of the gate type traveling frame 1, and the washing splash is scattered in all directions through the opening. Effectively prevented by the cover C in the state.

When the portal traveling frame 1 is retracted from the position shown in FIG. 2, the cover C gradually contracts accordingly. The cover C is in the most contracted form when the gate type traveling frame 1 is retracted to the storage position shown in FIG.

Thus, the cover body C has the rear end portion e ₂ of the gate type traveling frame 1
Since the predetermined section s is set to be longer than the maximum contraction length s' (FIG. 1) of the cover C, the cover C can be expanded and contracted. stroke
Even if s ₂ is not particularly extended, the moving stroke of the rear end e ₂ of the cover C (that is, the length of the predetermined section s) is set to be relatively long, and the sum of both strokes s ₂ , s is set. It is possible to set the determined traveling stroke s ₁ of the portal traveling frame 1 to be sufficiently long. As a result, the structure of the cover C itself can be simplified and downsized while ensuring the required travel stroke s ₁ of the portal travel frame 1.

Moreover, since the space Sp is formed on the installation surface E in the predetermined section s, which allows the entrance of the portal traveling frame 1 when the cover C is contracted most (when folded as shown in FIG. 1), Even though the predetermined section s is set to be relatively long as described above, the rearward limit of the gate type traveling frame 1 can be moved to the rear (left in FIG. 1) as much as possible, whereby the main part of the car wash machine can be closed. In the unused state (storage standby state), the size can be reduced as much as possible in the front-rear direction.

Although the rear end of the curtain 4 of the cover C is opened in the above-described embodiment, the rear end of the cover C, that is, the rear end of the curtain 4 is provided by a suitable shielding means in the present invention. You may make it fully closed, and in that case, the effect of blocking noise of the cover C and the effect of preventing washing splashes is further enhanced.

C. Effect of the Invention As described above, according to the present invention, the other end of the cover is movably supported within a predetermined section along the traveling direction of the gate type traveling frame on the installation surface, and the predetermined section is also supported. Since it is set to be longer than the maximum contraction length of the cover, the movement stroke of the other end of the cover (that is, the length of the predetermined section) is relatively long even if the expansion / contraction stroke of the cover is not particularly extended. It is possible to set the travel stroke of the portal travel frame, which is the sum of both strokes, to be sufficiently long, thus ensuring the required travel stroke of the portal travel frame while simplifying and downsizing the structure of the cover body. This can contribute to cost reduction.

In addition, a space is formed on the installation surface within the predetermined section to allow the entrance of the portal traveling frame when the cover is contracted most, so that the predetermined section can be set relatively long as described above. Regardless, the backward limit of the gate type traveling frame can be moved as far as possible to the rear, so that the main part of the car wash machine can be downsized as much as possible in the front-back direction when it is not in use (standby storage state). This is advantageous in reducing the space.
