Description

The present invention relates to a vehicle repair bench.
The vehicle bench according to the present invention can be used efficiently as a bench in any situation where the vehicle must be lifted to check the lower part that is difficult to see or to change tires when working in the workplace. Although not limited thereto, the present invention is particularly useful in a body shop as a bench for measuring, for example, dimensional elements of a vehicle in an accident.

It is known that there are problems in raising a vehicle to be repaired to a work place or a measurement bench. In fact, even if the vehicle is severely damaged, it is even difficult to move.
Some of the most widely used work benches (or measuring benches) consist of a platform combined with a pantograph type (or bowl-shaped) lifting device, and are from the ground when at the lowest position. The height is inevitably 40 to 50 cm. Therefore, it is necessary to push the vehicle and overcome such a difference in height, and such work is usually difficult if not impossible.

Some bench manufacturers manufacture benches that are tilted well to one end to make it easier to raise the vehicle when the vehicle is not severely damaged.
However, in the case of a sports car, the bench is not suitable for use in a sports car because it has a low-position spoiler that comes into contact with the floor or the bench itself when it is raised to the bench. Also, in the case of a damaged vehicle, the upward movement is definitely more difficult.

  Bench built into the floor is also known. Actually, a working recess is formed in the floor, and a bench lifting device composed of, for example, an electric and fluid pantograph lifting unit is disposed at the bottom of the working recess. This bench has a shape that complements the plan view shape of the working recess so that when the upper surface of the bench on which the vehicle is placed is completely lowered, it is substantially flush with the floor. It has become. By doing in this way, after moving a vehicle on a bench, without producing the problem by the difference in height, it can raise with a bench.

  However, this type of bench causes serious problems. When the bench is raised, the work recess necessarily remains open. This situation causes the problem of objects falling into the working recess (tools or trays may fall and break or damage the base of the lifting unit at the bottom) In addition, there is a risk that the operator may fall into the working recess.

The aim of the present invention is to eliminate the above-mentioned problems found in conventional types of benches by providing a bench that allows easy placement of the vehicle.
Under such an aim, an object of the present invention is to provide a vehicle bench capable of raising and lowering a vehicle without exposing a worker to a significant risk and without causing a risk of damaging a tool. It is in.

  Another object of the present invention is to provide a structurally simple vehicle bench.

  A vehicle bench that achieves these aims and objectives, and another objective that will become apparent later, is a vehicle bench provided with first lifting means for a table on which the vehicle is placed, and the first lifting means described above. Is disposed at the bottom of the working recess provided on the floor of the room where the vehicle bench operates, from a position that is substantially flush with the floor provided with the working recess, It is possible for the table to move in the vertical direction to a position raised from the floor, and the table has a shape that substantially complements the plan view shape of the working recess. The bench includes a second lifting and lowering means for the platform disposed between the bottom of the working recess and the platform, and the platform has a shape that complements the plan view shape of the working recess. And the second lifting means is disposed in the working recess. From the position, characterized in that to allow movement to a raised position, such as to block the working recess.

  Further features and advantages of the present invention will become more apparent from the following detailed description of preferred but non-limiting embodiments, illustrated by non-limiting examples in the accompanying drawings.

It is a perspective view when the bench for vehicles concerning the present invention is going up. It is front sectional drawing in the state which the vehicle bench of FIG. 1 lowered | hung completely. It is front sectional drawing when the bench for vehicles of Drawing 1 and Drawing 2 is going up.

It should be noted that anything that is already known in the patent examination process is judged not to claim a patent right but to be waived.
Referring to the drawings, a vehicle bench according to the present invention is generally indicated at 10. The bench 10 has a typical rectangular plan view shape, and a bench 10 for a table 15 on which a vehicle (not shown) is placed on the bottom 11 of a working recess 12 provided on the floor 13. 1 elevating means 14 is provided.

  The first elevating means 14 enables the vertical movement of the table 15 from a position substantially flush with the floor provided with the working recess to a position raised from the floor. For example, the first elevating / lowering means 14 is constituted by an electrohydrodynamic pantograph type elevating / lowering device 16 disposed in the central portion of the table 15. The space occupied by the pantograph type lifting device 16 in plan view is smaller than the plan view shape of the working recess 12 by providing a certain gap between the wall surface of the working recess 12 and the lifting device 16. Yes.

  In this embodiment, the stand 15 is of a type that constitutes a vehicle support surface of a measurement bench used by an operator of a vehicle body factory. For example, the representative structure can arbitrarily place a wheel. It is provided with two front-rear direction paths 17 provided with such a width as possible. The front-rear direction path 17 is supported by a frame composed of a front-rear direction member 18 and a cross member 19 so that a centering jig and other measuring devices can be fixed to the frame. It has become.

The platform 15 has a shape that substantially complements the plan view shape of the working recess 12, so that the working recess is closed when it is completely lowered.
Furthermore, the bench is provided with a second lifting means 20 for lifting and lowering the platform 21 disposed between the bottom 11 of the working recess 12 and the base 15 at the bottom of the working recess 12. The platform 21 has a shape that complements the plan view shape of the working recess 12.

The second elevating means 20 rises from a position where the platform 21 is lowered into the working recess 12 to a height where the platform 21 is substantially flush with the floor to a position where the platform 21 closes the working recess. 21 can be moved in the vertical direction.
In this embodiment, the platform 21 is composed of a plurality of metal beam members 22, which have a U-shaped cross section, and have through holes for surrounding and moving the pantograph type lifting device 16. They are integrally fixed to each other so as to be formed in the central portion. As a matter of course, such a platform can be provided by using other beam members and panels, and can be configured as an integral structure.

  In the present embodiment, the second elevating device 20 is constituted by a pneumatic spring 24 of a substantially known type, and is disposed between the bottom 11 of the working recess 12 and the platform 21. In particular, in the present embodiment, four pneumatic springs 24 are disposed at the four corners of the platform 21. The pneumatic spring 21 is connected to an air supply device (not shown), and the pneumatic spring 21 is expanded and contracted by the air supply device.

The operation of the pantograph type lifting device 16 is controlled by an electronic control unit 25 that can be operated by an operator using an operating device.
In order to operate the bench optimally, the first elevating means and the second elevating means are arranged so that the platform 21 follows and rises when the table 15 is raised, and the platform 21 is lowered when the table 15 is lowered. It is necessary to cooperate with each other.

  The difference in drive time of the first lifting means relative to the second lifting means (for raising and lowering the platform in relation to raising and lowering the platform) can be preset in the electronic control unit 25 (in this case, The air supply device connected to the pneumatic spring 24 is directly controlled by the electronic control unit 25), or the difference in the driving time is adjusted by using a detection system to move the table in a predetermined vertical direction. It is also possible to perform parallel movement of the platform corresponding to this by driving with a pneumatic spring a predetermined time after detection.

As another embodiment, it is of course possible to configure the second lifting means by another type of translation actuator such as a pneumatic or fluid cylinder or an electromechanical actuator. Similarly, the first lifting / lowering means can also be constituted by another type of device.
As described above, it has become clear that the present invention achieves the above-mentioned aims and objects. In fact, the present invention provides a vehicle bench that can easily lift the vehicle.

As a result, it is possible to use a bench that is provided with a support base that is flush with the floor when the vehicle is mounted, and that is built into a working recess provided on the floor, and the step that the vehicle must get over. Can be prevented from occurring.
In addition, the problem of the work recess that appears when the stand rises with the vehicle is that when the stand is raised, the work recess rises from the bottom of the work recess to the height of the floor. It was solved by introducing a covering platform.

The present invention described above can be modified and changed in various ways, all of which are included in the scope of the appended claims, and all the constituent elements can be replaced with technical equivalents in detail. Is possible. In addition to the dimensions, the members used can be changed as necessary and according to the state of the technology as long as they are suitable for a predetermined use.
