Abstract
A telescoping motorized lift platform, having a plurality of nested telescoping sidewall columns. The upper sidewall column includes a platform and the remaining sidewall columns have sidewalls extending preferably to the adjacent outer nested sidewall columns. A base structure is included for support of the telescoping motorized lift platform. The base structure is provided with multiple rollers or casters for movement and positioning of the lift platform. The lift platform also includes means for raising and lowering. As the lift platform is raised or lowered, the nested sidewall columns will also raise and lower, providing a continuous shield from contact with the means for raising and lowering.
Description
- This invention relates to the art of telescoping platforms, and more particularly to telescoping motorized lift platforms having a plurality of nested, telescoping columns.
- It is desirable to have a telescoping platform that is portable, easily adjustable, and safe for the operator or other people, animals, or objects near the telescoping lift platform. In many environments, such as warehouses, offices, clinics, restaurants, factories, and machine shops, it is often necessary to use a telescoping lift platform to raise or lower a person, animal, or object to a desired height. For example, if the telescoping platform were to be used in a veterinary clinic to support an animal, it would be very important for the telescoping platform to have all of the above mentioned features for the protection of the animal and the platform operator. Telescoping platforms generally include a single work platform and a means for raising and lowering the platform, such as a scissors linkage lift, as described in U.S. Pat. Nos. 4,171,120 and 6,044,927, or a jack screw lift, as described in U.S. Pat. No. 6,502,667. These previous designs of telescoping platforms typically have exposed the means for raising and lowering the platform without any shielding from contact, which creates a safety hazard for those operating the telescoping platform, or other people, animals, or objects near the telescoping platform. The exposed means for raising and lowering of the platform also creates an unsightly view of the potentially dangerous mechanics of the telescoping platform. When the telescoping platform is utilized in a clinical or office type of environment for example, it would be advantageous to provide a telescoping lift platform where the means for raising and lowering the platform are out of sight.
- Covers for adjustable height structures have been provided for covering the means for raising and lowering a platform. These cover systems are commonly of a pleated design and are made from a non-rigid material, such as cloth or soft plastic materials.
- Consequently, the need exists to provide a telescoping motorized lift platform that does not suffer the drawbacks of the previous designs, and provides a safer environment for the operator or other people, animals, or objects near the telescoping lift platform, by shielding the means for raising and lowering from contact, and furthermore is more aesthetically appealing to the eye so as to allow its use in a greater selection of environments.
- The present invention relates to a telescoping motorized lift platform, advantageously configured to provide a lift platform that has improved safety features by shielding and protecting the operator or others nearby from the potentially harmful raising and lowering means. In general, this is achieved by providing a plurality of nested telescoping sidewall columns whereby the upper sidewall column preferably includes a platform and the remaining sidewall columns have sidewalls extending preferably to the adjacent outer nested sidewall columns. Each sidewall column preferably includes a lower inner side strip and an upper outer side strip for the purpose of raising and lowering each sidewall column. As the lift platform is raised or lowered, the nested sidewall columns will also raise and lower, providing a continuous shield from contact with the means for raising and lowering.
- A base structure is preferably included for support of the telescoping motorized lift platform. Additionally, the base structure may be supported by multiple rollers or casters for movement and positioning of the lift platform. A plurality of stop brackets are preferably attached to the base structure for supporting the sidewall columns. The lift platform may also include means for raising and lowering attached to the base structure, including but not limited to scissors linkage, jack screw, or other conventional motorized, hydraulic, or manually operated lifting apparatus.
- The telescoping motorized lift platform preferably includes four sides, although it is within the spirit of the invention to have a telescoping motorized lift platform taking on any practical shape to meet the needs of a particular application, such as but not limited to, a round, oval, or triangular telescoping motorized lift platform.
- To operate the lift platform, an operator would activate the means for raising and lowering. This may be accomplished by preferably applying pressure to a footswitch, although other simple control methods such as a switch or pushbuttons are within the spirit of the invention. The means for raising and lowering would then provide vertical movement of the platform and upper sidewall column. By way of example, as the lift platform is being raised by the means for raising and lowering, first the platform and upper sidewall would move in an upward direction. At a point at which the lower inner side strip of the upper sidewall column comes into contact with the upper outer side strip of the first nested sidewall column, the first nested sidewall column will also move in an upward direction. This process will repeat with all or some of the sidewall columns being raised by the previously raised side wall, with the platform ending up at the operator's desired position. At all times through this raising process, the means for raising and lowering are shielded from being in contact with the operator or those nearby. The process as described above is reversed to have the platform lowered.
- Accordingly, it is an object of the invention to provide a telescoping motorized lift platform that will provide a safe environment for the operator or other people, animals, or objects near the telescoping platform by shielding the means for raising and lowering from contact.
- It is another object of the invention to provide a telescoping motorized lift platform that is more aesthetically appealing to the eye so as to allow its use in a greater selection of environments.
