- the opening is made underneath the vehicle, in which case the section of the opening is much smaller but considerably deeper, sometimes as deep as 1 metre.
- the object of making the opening is to allow the air insufflated into the booth to pass through the grated metal floor and be channelled to the ducts which lead to the outside through what is known as the "lower aspiration plenum".
- the civil work is omitted and instead the floor of the booth is raised some 30 cm in relation to the plane of the shop floor.
- the booth In order for the vehicle to access the inside of the booth, the booth is equipped with ramps which may be positioned either inside or outside of the booth.
- the operator may observe that the roof of the vehicle is too high, making it necessary to use step stools, pedestals, etc. Likewise, in order to paint the lower part of the body of the vehicle, the operator must either crouch down in a very uncomfortable position or use conventional elevators to raise the vehicle to a more suitable working position.
- the system of the invention has been created which consists of installing a metal floor inside the paint booth with one or more zones or the entire floor made of grates in relation to another platform that supports different loads, thus making it possible to change the position of the operator in relation to the vehicle or vice versa, depending on the job requirements.

Abstract
Description
- The present invention refers to a system for positioning and raising-lowering an automobile and operator on a platform located inside a paint booth and/or similar installation.
- In conventional booths, it is often necessary to make an opening in the floor measuring approximately 30 cm deep and of a size similar to that of perimeter of the booth.
- In some cases, the opening is made underneath the vehicle, in which case the section of the opening is much smaller but considerably deeper, sometimes as deep as 1 metre.
- The object of making the opening is to allow the air insufflated into the booth to pass through the grated metal floor and be channelled to the ducts which lead to the outside through what is known as the "lower aspiration plenum".
- In some cases, the civil work is omitted and instead the floor of the booth is raised some 30 cm in relation to the plane of the shop floor.
- In order for the vehicle to access the inside of the booth, the booth is equipped with ramps which may be positioned either inside or outside of the booth.
- Once the vehicle is inside the booth and ready to be painted, the operator may observe that the roof of the vehicle is too high, making it necessary to use step stools, pedestals, etc. Likewise, in order to paint the lower part of the body of the vehicle, the operator must either crouch down in a very uncomfortable position or use conventional elevators to raise the vehicle to a more suitable working position.
- To overcome these inconveniences, the system of the invention has been created which consists of installing a metal floor inside the paint booth with one or more zones or the entire floor made of grates in relation to another platform that supports different loads, thus making it possible to change the position of the operator in relation to the vehicle or vice versa, depending on the job requirements.
- The system of the invention therefore consists of installing a central platform, known as the loading platform where the vehicle is positioned, and an additional concentric platform surrounding the central platform known as the working platform where the operator or operators are positioned.
- The working platform may be a one-piece unit or may be divided into different zones, in which case the different zones of the platform may be connected to one another by means of interlocking devices with the working platform moving up and down vertically.
- The loading platform is equipped with hydraulic or pneumatic elevating devices which move the platform vertically and move the working platform once it is interlocked with the loading platform.
- The working platform moves along vertical rails located near the perimeter of the booth forming a kind of post that emerges from the floor of the booth.
- The clamping devices installed on sections located near these guides are used to fix the position of the working platform at two levels, high and low.
- The outer perimeter of the loading platform is related to the inner perimeter of the working platform by means of a canvas that makes it possible to insufflate air into the booth, which is then driven to the outlet ducts, preventing it from exiting through the free space between the platforms when they are positioned at different heights.
- In order for the vehicle to access the working platform inside the booth, both platforms must be in the low position, for example, approximately 10 cm from the floor, at which point the vehicle enters the booth using a wedge or ramp.
- Once the vehicle is positioned on the loading platform, both platforms are raised and clamped together using bolts, pins, etc. They are raised to a height of approximately 30 cm, which is considered the "lower plenum".
- At this point, the booth is now ready for the general painting of the vehicle to begin.
- When the operator wants to paint the roof of the vehicle, he raises both platforms at once to a height of approximately one metre, using mechanical or hydraulic devices to clamp the working platform to the sides of the booth in the vertical rails along which the platform moves and releasing the loading platform so that it is lowered to a height of 30 cm, a suitable height for painting the roof of the vehicle.
- Once the roof is painted, the operator raises the loading platform again to the point where it is even with the working platform, which is then released from the clamps fastening it to the sides of the booth and both platforms are lowered to the lower working level.
- If it is necessary to paint the lower part of the vehicle, the loading platform is moved to the upper position, while the working platform remains at the lower level, fastened to the sides of the booth.
- Once the lower part of the vehicle has been painted, the loading platform is lowered to the low position for touch-ups, paper removal, drying, etc.
- Once the painting process is complete, the two platforms are lowered together using the elevation equipment that may be hydraulic, pneumatic or based on pulleys and cables or, depending on manufacturing costs, could be made of independent elevation devices, one for the loading platform and another for the working platform. In this position, the working platform is a single element but may be composed of separate zones or portions connected to one another by interlocking elements such as the ones mentioned above in order to form independent working zones.
- Between the two platforms and between the working platform and the inside surface of the booth, around the perimeter, the booth is equipped with flexible laminar surfaces such as canvas, which can be closed in an airtight fashion to ensure not only that the air is forced out of the spaces mentioned but also forced to exit through the bottom of the platforms to the outside.

platform 7 has two operating positions, a lower position which is represented in figures 1, 2, 3 and 6 and an upper position represented in figures 1, 2 and 4. In these two end positions, theworking platform 7 is clamped and theloading platform 8 released from the working platform, and the loading platform is moved up or down to a higher position, figure 1, or lower position, figure 2 in respect of the working platform. - The lower working position is reached when both platforms, clamped together, are raised together from the lower level to a height of approximately 30 cm. At this point, the working platform is clamped and when the loading platform is released, it is raised to the higher level.
- With the loading platform at a higher level the free space between the two platforms is covered with a flexible, elastic or similar type of
canvas 9a, which leads the air to ducts, either through the centre of the loading platform or through the working platform, whichever is most convenient. - The
loading platform 8, when it is lowered and clamped once again to the working platform, can be raised to the highest point and from there, once the loading platform is relapsed from the working platform and the working platform is clamped to the sides, the loading platform is lowered to facilitate the painting of the roof. - The clamping consists of equipping the working platform with a series of 10 locks that are activated and moved by means of their respective
hydraulic cylinders 11 so that they are locked or unlocked atpoints 12 of the loading platform or inconformations 13 pertaining tovertical section 14 that emerge in this direction from the floor of the booth. - In addition, the working platform is equipped with
sections 15 that are coupled with thesections 14 in order to ensure that the vertical movement of the platforms is perfectly balanced. - The working platform may be a one-piece unit or composed of sections coinciding in length with the rectangular sides of the working platform. The sections can be coupled and uncoupled using the corresponding locks mentioned above.
