Description
BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an elevating device, and more particularly to an elevating device for planer displayers or the like.

[0003] 2. Description of the Prior Art

[0004] Typical televisions, monitors, displayers, such as the planer displayers or the like, are normally disposed on top of a desk or a table and may not be suitably shielded or covered and thus may be easily dirtied.

[0005] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional televisions, monitors, displayers or the like.

SUMMARY OF THE INVENTION

[0006] The primary objective of the present invention is to provide an elevating device for elevating and for receiving and storing and shielding and covering the televisions, the monitors, the displayers or the like and for preventing the facilities from being dirtied.

[0007] In accordance with one aspect of the invention, there is provided an elevating device comprising a housing including an upper portion having an opening formed therein, an object slidably received in the housing, and means for moving the object inward of the housing in an inward storing position and outward of the housing in an outward working position.

[0008] The object may be a television, a monitor, or a displayer or the like, and preferably a planer displayer.

[0009] The moving means includes an actuator having a tube secured to the object, and means for activating the tube to move inward and outward through the opening of the housing.

[0010] The activating means includes a motor disposed in the housing and having a bolt extended therefrom and threaded to the tube for moving the tube and the object up and down when the bolt is rotated by the motor.

[0011] A device is further provided for guiding the tube to move up and down relative to the housing and includes a casing secured in the housing and having an orifice formed therein for slidably receiving and guiding the tube.

[0012] A device is further provided for guiding the object to move up and down relative to the housing and includes at least one post vertically disposed in the housing, a seat slidably secured to the post for supporting the object and for guiding the object to move up and down along the post.

[0013] A table includes an aperture formed therein, the housing is secured to the table, the object is aligned with the aperture of the table for allowing the object to be moved up and down through the aperture of the table.

[0014] Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015]FIG. 1 is a perspective view illustrating the attachment of an elevating device in accordance with the present invention onto a table;

[0016]FIG. 2 is a partial exploded view of the elevating device;

[0017]FIG. 3 is a partial cross sectional view taken along lines 3-3 of FIG. 2; and

[0018]FIG. 4 is a plane schematic view illustrating the operation of the elevating device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] Referring to the drawings, and initially to FIGS. 1-3, an elevating device in accordance with the present invention comprises a housing 10 including an opening 11 formed in the upper portion thereof and including a cover 14 detachably secured to the front portion thereof. One or more guide posts 12 are vertically disposed in the housing 10. A seat 23 includes one or more ears 24 attached thereto and slidably engaged on the posts 12 for guiding the seat 23 to move up and down along the posts 12. The housing 10 includes a control panel 13 attached thereto. The housing 10 may be attached to a desk or a table 70 or the like. The table 70 includes an aperture 71 formed in the upper portion thereof.

[0020] An object 30, such as an electric facility, including a television, a monitor, a computer displayer, particularly a planer or liquid crystal displayer that has a planer structure, is secured on top of the seat 23 with fasteners or the like. The object 30 includes an upper portion 33 having a shape or a size or an area equals to that of the opening 11 of the housing 10 for allowing the object 30 to be moved upward and outward through the opening 11 of the housing 10 and/or the aperture 71 of the table 70 (FIG. 1). A control device 25 (FIGS. 3, 4), such as an electric circuit or a processor unit, may be provided and coupled to the object 30 for controlling and operating the object 30.

[0021] An actuator 2, such as a pneumatic cylinder, a hydraulic cylinder, or a motorized device is disposed in the housing 10 and disposed below the seat 23 for moving the seat 23 and the object 30 upward and outward of the housing 10 and inward of the housing 10. The actuator 2 includes a casing 20 disposed in the lower portion of the housing 10 and having an orifice 26 formed in the upper portion thereof. A motor 21 is disposed in the lower portion of the housing 10 and disposed in the casing 20 and includes a bolt 22 secured thereto and extended upward therefrom for allowing the bolt 22 to be rotated and driven by the motor 21. A tube 27 is threaded onto the bolt 22 and extended through the orifice 26 of the casing 20 and includes an upper end secured to the seat 23.

[0022] In operation, as shown in FIGS. 3, 4, the tube 27 and thus the seat 23 and the object 30 may be moved up and down along the posts 12 when the bolt 22 is driven or rotated by the motor 21, such that the object 30 may be moved upward and outward through the opening 11 of the housing 10 and/or the aperture 71 of the table 70 to an outward working position, and may be moved downward and received in the housing 10 in an inward receiving position by the actuator 2. The control panel 13 may be coupled to the control device 25 and/or the object 30 and/or the actuator 2 for operating or actuating the control device 25 and/or the object 30 and/or the actuator 2. The upper portion 33 of the object 30 is preferably flush with the upper portion of the housing 10 and/or the upper portion of the table 70 for allowing the object 30 to be suitably covered and shielded and stored in the housing 10 and/or the table 70.

[0023] The sliding engagement of the tube 27 in the orifice 26 of the casing 20 may further stably guide the tube 27 to move up and down relative to the housing 10 and may prevent the tube 27 from moving laterally relative to the housing 10 and the casing 20.

[0024] Accordingly, the elevating device in accordance with the present invention may be used for elevating and for receiving and storing and shielding and covering the televisions, the monitors, the displayers or the like and for preventing the facilities from being dirtied.

[0025] Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
