Office furniture description
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to an office furniture light structure,
more particularly to a lighting device that can be moved to a suitable
position on a piece of office furniture to provide sufficient illumination.
(b) Description of the Prior Art
With reference to FIG. 1 in an office where the main source of
light comes from ceiling lighting fixtures, the area beneath a shelf
1 and a table surface 11 is relatively dark. In general, a conventional
lighting device 13 (e.g., a fluorescent lamp) is mounted on a bottom
side of the shelf 1 to illuminate that area. However, as the lighting
device 13 can only mounted at a fixed position and is not removable,
the lighting zone is restricted to that below the lighting device
13. The other dark areas or zones are not properly illuminated.
Improvements are therefore necessary.
SUMMARY OF THE INVENTION
In the present invention, a securing element is adapted to be mounted
on a piece of office furniture in a suitable position. The securing
element is provided with at least one outwardly extending movable
element. The movable element has one end connected to a lighting
device in a movable manner. In use, through displacement of the
movable element, the lighting device can be moved to a suitable
position.
A primary object of the present invention is to provide an office
furniture light structure that includes a securing rail that has
two ends respectively provided with an outwardly extending movable
plate. The movable plates have one end insertably disposed in a
track of the securing rail by means of rollers. A lighting device
is movably connected to the other end of each of the movable plates.
In use, by means of the rollers displacing in the track of the securing
rail, the lighting device can displace left and right. Besides,
by means of the movable plates, the lighting device can be pulled
outwardly or pushed inwardly with respect to a bottom side of a
shelf to sufficiently illuminate the area beneath the shelf which
is relatively dark.
Another object of the present invention is to provide an office
furniture light structure that includes a fixed slide rail and outwardly
extending movable slide rails provided at both ends of the fixed
slide rail. The movable slide rails are connected to the fixed slide
rail by means of connecting elements. A lighting device is connected
to free ends of the movable slide rails by means of connecting elements.
In use, by means of the movable slide rails and the fixed rail that
can displace forwardly and rearwardly as well as left and right
with respect to a bottom side of a shelf, the lighting device can
be pulled outwardly or pushed inwardly or can displace left and
right with respect to the bottom side of the shelf to sufficiently
illuminate the area beneath the shelf and above a table surface
where it is relatively dark.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIG. 2 a preferred embodiment of an office furniture
light structure according to the present invention is shown to include
a securing element and a lighting device 3.
The securing element in this embodiment is a securing rail 2 provided
on a bottom side 12 of a shelf 1 of a piece of office furniture.
The securing rail 2 is provided with a track 22 having two ends.
Two movable plates 23 are respectively provided at the ends of the
track 22 at suitable positions and extend outwardly therefrom. One
end of each of the movable plates 23 is insertably mounted in the
track 22 of the securing rail 2 by means of a roller 25. The roller
25 slidably displaces along the track 22 to enable the corresponding
movable plate 23 to displace left or right of the track 22. The
securing rail 2 is further provided a stop block 24 at either distal
end to restrict displacement of the rollers 25 within the space
defined by the track 22 between the stop blocks 24 and to thereby
prevent slippage of the rollers 25 out of the track 22. The stop
blocks 24 are secured on the bottom side 12 of the shelf 1 by means
of retaining elements 21. In this embodiment, the retaining elements
21 are screws but, as well known in the art, can be substituted
by other elements. The lighting device 3 is pivotally connected
to the other end of each of the movable plates 23 on a bottom side.
In this embodiment, the lighting device 3 is a fluorescent lamp.
The movable plates 23 and the lighting device 3 are movably connected
by means of connecting elements 27.
After assembly, by means of the rollers 25 at one end of each of
the movable plates 23 that can slidably displace along the track
22 of the securing rail 2 the lighting device 3 can displace left
and right of the securing rail 2. Besides, as the movable plates
23 can swing sideways, the lighting device 3 can be pulled outwardly
or pushed inwardly with respect to the bottom side 12 of the shelf
1 so that the relatively dark area beneath the shelf 1 and above
the table surface 11 is properly illuminated and there is no more
shade.
FIGS. 3 and 4 show another embodiment of the present invention.
In this embodiment, the securing element is a fixed slide rail 4.
The fixed slide rail 4 is provided on a bottom side 12 of a shelf
1 (see FIG. 1) and includes an upper slide rail 41 and a lower slide
rail 43. The lower slide rail 43 is capable of slidable displacement
on the upper slide rail 41. The upper slide rail 41 is secured to
the bottom side 12 of the shelf 1 by means of retaining elements
21. In this embodiment, the retaining elements 21 are but not limited
to screws. The lower slide rail 43 is provided with an upwardly
projecting stop plate 45 at either distal end such that the displacement
of the lower slide rail 43 on the upper slide rail 41 is restricted
to the space defined by the two stop plates 45.
The lower slide rail 43 is further provided with a plurality of
outwardly extending movable slide rails 5 at both ends thereof.
The movable slide rails 5 are each provided with upper and lower
sliding rails 51 53 the lower sliding rails 53 being capable of
slidably displacement on the upper sliding rails 51. Each upper
sliding rail 51 has a substantially central portion connected to
a bottom side of the lower slide rail 43 of the fixed slide rail
4 by means of connecting elements 27. Each lower sliding rail 53
has two ends respectively provided with an upwardly projecting stop
55 such that slidable displacement of the lower sliding rail 53
is restricted to the space defined by the projecting stops 55 at
both ends. A lighting device 3 is connected to the end of each of
the lower sliding rails 53 opposite to the fixed slide rail 4 at
a bottom side by means of connecting elements 27. In this embodiment,
the lighting device 3 is a fluorescent lamp.
With reference to FIGS. 4 and 5 the upper and lower slide rails
41 51 and the upper and lower sliding rails 43 53 are provided
with folded edges 46 on opposed sides thereof. Balls 47 are provided
in the folded edges 46. By means of the rolling movement of the
balls 47 the lower slide rail 43 and the lower sliding rail 53
can slidably displace on the upper slide rail 41 and the upper sliding
rail 51 respectively. Between the folded edges 46 on the side of
the adjacent balls 47 there are provided securing frame blocks
48 such that the upper and lower slide rails 41 43 can be movably
connected and that the upper and lower sliding
rails 51 53 can be movably connected.
After assembly, by means of the lower sliding rail 53 that displaces
left and right on the upper sliding rail 51 and by means of the
lower slide rail 43 that displaces left and right on the upper slide
rail 41 the lighting device 3 can be pulled outwardly or pushed
inwardly or can displace leftward or rightward with respect to the
bottom side 12 of the shelf 1 so that the area beneath the shelf
1 and above the table surface 11 can be sufficiently illuminated.
Although the present invention has been illustrated an described
with reference to the preferred embodiment thereof, it should be
understood that it is in no way limited to the details of such embodiment
but is capable of numerous modifications within the scope of the
appended claims. |
