Vehicles take a number of different shapes and sizes, and therefore often require specialized lifts. Moreover, different lifts may be required for different projects. For example, there may be instances where it is advantageous for the vehicle lift to be positioned under the frame of the vehicle. In other instances, it may be advantageous for the vehicle to be lifted under its wheels. It is burdensome to purchase and store a separate lift for each vehicle and every occasion. Accordingly, it would be beneficial to have a lift that can be modified to fit a variety of vehicles.
The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is not intended to identify critical elements of the invention or to limit the scope of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description presented below.
In one embodiment, a transformable table has a lifting mechanism and a platform secured to the lifting mechanism. The platform has a stationary panel; a plurality of expansion panels positioned on either side of the stationary panel; and a plurality of extension panels in slidable engagement with the expansion panels and the stationary panel. The stationary panel, the expansion panels, and the extension panels are formed from a plurality of hollow tubes, and the hollow tubes re spaced apart a predetermined distance to form forming spaces therebetween and are secured together with a reinforcement member. The expansion panels extend laterally outward from the stationary panel, and the extension panels extend longitudinally outward from the connection with the expansion panels and the stationary panel.
In another embodiment, a transformable table has a frame, comprising a base and a hydraulic pump secured to the base. A platform is secured to the frame via a plurality of connection members. The platform has first and second platform supports that extend substantially along the length of the base. The platform further includes a plurality of expansion supports that extend perpendicularly between, and are supported on, the platform supports. Each expansion support has two expansion support members spaced apart so as to form a channel therebetween. A stationary panel comprising a plurality of hollow tubes secured together at predetermined intervals is secured atop the expansion supports as part of the platform. And a plurality of expansion panels us adjustably secured to the expansion supports, each expansion panel including a plurality of hollow tubes secured together at predetermined intervals; and a brace secured to an underside of the expansion panel. The brace has a channel formed therein. The platform still further includes a plurality of extension panels. Each extension panel has a plurality of hollow tubes secured together at predetermined intervals via a reinforcement member. The hollow tubes of the extension panel are positioned in the spaces of the expansion panels. Rollers are positioned between the space in the expansion supports, and the brace engages with the rollers such that the expansion panels are movable in a laterally outward direction from a contracted position to an expanded position. The extension panels are movable in a longitudinally outward direction from a contracted position to an expanded position.
In still another embodiment, a transformable table has a platform having a stationary panel; a plurality of expansion panels positioned on either side of the stationary panel; a plurality of extension panels in slidable engagement with the stationary panel and the expansion panels; and step plates secured under each of the respective expansion. The stationary panel, the expansion panels, and the extension panels are formed from a plurality of hollow tubes, and the hollow tubes are spaced apart a predetermined distance to form spaces therein and are secured together with a reinforcement member. The extension panels are positioned in the spaces formed between the hollow tubes of the stationary panel and the expansion panels such that the expansion panels translate laterally outward from a position adjacent the stationary panel and the extension panels translate longitudinally outward from engagement with the stationary panel and the expansion panels. The table further includes a platform support system that includes a plurality of platform supports extending lengthwise along, and secured to, the outer edges of the expansion panels; and a plurality of expansion supports extending between the platform supports; and a plurality of connection members extending lengthwise between, and secured to, the expansion supports. The expansion panels engage with rollers secured to the expansion supports to translate from the contracted position to the expanded position.
Embodiments of vehicle lifts are described herein. In one embodiment of the invention, a transformable table 100 includes a base frame 105 having an opposing set of legs 125 connected to a platform 140 that includes a plurality of expansion panels 180, extension panels 185, and stationary panels 190.
The base frame 105 may be, for example, a four sided structure, such as that shown in
A hydraulic cylinder 120, or other lifting mechanism, may be attached to one side of the base 105 for lifting the platform 105. It shall be appreciated that the lifting mechanism is configured to lift the platform 105 such that the platform 105 is maintained in a substantially flat position to prevent a vehicle resting thereon from shifting while the platform is raised from a lowered to a raised position.
As noted above, the platform 140 includes a plurality of expansion panels 180, a plurality of extension panels 185, and a stationary panel 190. As shown in
The panels 180, 185, and 190 may be formed of hollow tubes, for example, square tubes, to provide a flat surface for supporting a vehicle. However, other shapes of tubes may be acceptable, including cylindrical tubes. The tubes of the various panels 180, 185, and 190 may be uniformly sized such that the surface of the platform 140 is congruous.
The hollow tubes 200 of the panels 180, 185, 190 may be secured together at predetermined intervals such that there is space between each of the tubes 200. The space between the tubes 200 of the expansion panel 180 may be defined by the size of the tubes 200 of the extension panel 185, and vice versa. For example, if the tubes 200 of the expansion panel 180 and the extension panel 185 are uniformly sized (e.g., 1 inch square), the tubes 200 of the expansion panel 180 are spaced to allow for the tubes 200 of the extension panel 185 to fit therebetween. Spacers 217 may be inserted between various tubes 200 which may aid in ensuring correct spacing between the tubes 200.
A brace 210 may be provided on either longitudinal end of the expansion panel 180, and may be secured to the panel 185 via any fastening means. The brace 210 may include a conduit 212 which engages with a rib 165 as described below. A brace plate 215 may be provided along the inside lateral edge of the brace 210. An expansion bracket 150 is secured around the underside edge of the brace plate 215. As described in greater detail below, the brackets 150 secure the expansion panels 180 to expansion panel supports 147 through an open channel between the expansion panel supports 147 (
As shown in
Now referring to
A rib 165 may be secured to the platform support 145 to engage with the conduit 212 in the brace 210. Rollers 160 may be placed on either side of the rib 165, and a pin 170 may be inserted through the rollers 160,the apertures in the expansion panel supports 147, and the rib 165.
Expansion panel spring loaded latches 235 may be provided along the expansion panel end plates 225. The expansion panel spring loaded latch 235 may include a spindle 237 extending from a handle 236, and a spring 238. The spindle 237 may be inserted through an aperture in a spring panel 239 attached to an outside edge of the connection member 155 or a top edge of the platform supports 145. The spring 238 may be received onto the spindle 237 such that the spring 283 abuts the spring panel 239 opposite the handle. The end of the spindle 237 may be inserted through an aperture in an inside edge of the inside expansion support member 147 and a respective corresponding aperture in the brace 210 to lock the expansion panel 180 in the contracted position.
To move the expansion panel 180 into the expanded position, the handles 236 are pulled away from the respective expansion supports 147, causing the springs 238 to contract against the spring panels 239, and the end of the spindles 237 to leave the apertures in the respective expansion supports 147 and braces 210. With the expansion panel spring loaded latches 235 disengaged from the brace 210 and the expansion support 147, the respective expansion panel 180 can be moved laterally outward from the stationary panel 190 to extend the width of the table 100.
When the expansion panel 180 is in the desired position, the latches 235 may be released, and may engage with apertures located along the length of the expansion panel 180 to lock the expansion panel 180 in position.
Step plates 255 may be provided under the expansion panels 180. When the expansion panel 180 is in the expanded position, the step plate 255 may provide a secondary surface which may be useful to prevent parts and/or tools from falling to the floor, and may also reduce the risk of an accident occurring when a vehicle is loaded onto the table 100. The step plates 255 may be supported by connection members 155 and/or the platform supports 145.
The platform 140 may be secured to the base frame 105 via the connection members 155. To allow the platform 140 to be removed from the base frame 105, the connection members 155 may be mechanically secured to the base frame 105, for example, via nuts and bolts, clevis pins, or other appropriate mechanical fasteners.
Referring now to
To move the extension panel 185 from the contracted position (
The spring loaded handle 360 may include a pin 368 attached to a body portion 367 of the handle 360, and a spring 369 may be secured to an end of the handle 460 opposite the pin 368 such that the spring 369 is positioned inside the handle 230. The spring 369 may bias the spring loaded handle 360 away from the handle 230.
A spring lockout 370 may be secured (e.g., welded or otherwise attached) to the end plate 225 of one of the tables 100. For example, each table 100 may have a spring lockout 370 attached to the left end plate 225 as shown in
To lock two tables 100 together, the handles 230 of the respective tables 100 may be placed adjacent one another. The spring loaded handle 360 may be inserted through the spring lockout 370 and rotated such that the pin 368 may pass through the slot 371 when a force is exerted on the handle 360. Once the pin 368 has passed through the slot 371, the handle 360 may be rotated such that the pin 368 contacts the lockout 370, preventing the spring 369 from biasing the spring loaded handle 360 back through the lockout 370 (i.e., the locked position). In the locked position, the spring loaded handle 260 engages with the adjacent handles 230 of the tables 100, thus connecting the two tables 100 together.
In still another embodiment, the table 100 may be equipped with a bar movably mounted to the platform 140 (e.g., at an underside of the platform 140). The table 100 may further have a socket for receiving a bar. To connect multiple tables 100 together, the bar may be pulled (or otherwise partially disengaged) from a first table 100 to be received by the socket in a second table 100. The bar may be held into place with acceptable mechanical fastening mechanisms, including but not limited to pins (spring loaded or otherwise), bolts, et cetera.
When the platform 100 is in the lowered position, the top of the platform may not be flush with the ground. Accordingly, ramps may be configured to attach to the platform 100 such that the vehicle can drive up the ramp to its position atop the platform 100. While many configurations of ramps may be acceptable, in one embodiment, the ramps may include at least one hook which may engage with the pin 245 in the extension panel 185 to attach the ramp to the platform 100.
Additionally, one end of the platform 100 may be designated the “front” of the platform, and stoppers may be provided on the ends of the panels 180, 185, and 190 to prevent the vehicle from rolling off the front of the platform 100. For example, the stoppers may have a substantially vertical configuration and may be welded, bolted, or otherwise attached to the “front” of the platform 100. If the vehicle rolls toward the front of the platform 100, the stoppers may prevent the vehicle from falling off the platform 100. It shall be understood by those of skill in the art that it may be preferable for the stoppers to be removably attached to the platform 100 such that the stoppers may be provided at both the front of the platform and the back of the platform to prevent the vehicle from falling off the front or the back, while also allowing the vehicle to be driven atop the platform.
Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present invention.
