Clamp-based stand and a pedestal for holding the same

A stand device for an article such as a lamp or a fan includes a holding post which has at its lower end a clamp base for mounting the holding post, and a pedestal for receiving and holding the clamp base. The pedestal has a pedestal housing to receive the clamp base and an interior integral seat plate which can be clamped by the clamp base. The stand device can be positioned by means of either one of the clamp base and the pedestal.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
This invention relates to a stand device having a clamp base, for use in 
clamp lamps, fans or the like, and particularly to one incorporating a 
pedestal for holding the clamp base thereof. 
2. Description of the Related Art 
A clamp lamp typically has a clamp member at the bottom thereof to clamp 
the edge of a desk or the rim of a plate so as that it can be fixed to the 
latter. Generally, the clamp member has a pair of jaws which are formed on 
a pair of pivoted levers. Since the levers should have a sufficient length 
so as to provide an efficient clamping force, the application of clamp 
lamps is limited to desks or other supports having edges with sufficient 
projecting length for clamping. Clamp lamps can not be mounted on a desk 
or support which has no projecting edge or whose edges are relatively 
short. 
SUMMARY OF THE INVENTION 
Therefore, the objective of the present invention is to provide a 
clamp-based stand device with a pedestal so that the stand device can be 
positioned on a desk or the like either by the pedestal or the clamp base 
thereof. 
According one aspect of the invention, a stand device comprises: 
a holding post having a lower end; 
a clamp base connected to said lower end for mounting the holding post; and 
a pedestal for mounting the holding post, the pedestal having a pedestal 
housing for receiving the clamp base and a seat plate coupled integrally 
with the pedestal housing to be clamped by the clamp base. 
According to another aspect of the invention, a pedestal for holding a 
clamp base of a stand device, comprises a pedestal housing for receiving 
the clamp base, and a seat plate integrally coupled with the pedestal 
housing to be clamped by the clamp base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Referring to FIGS. 1 to 6, the first preferred embodiment according to the 
present invention is shown to include a light unit 15, a light unit holder 
16 which has an upper end connected to the light unit 15 and a lower end 
connected to a clamp base 11 for clamping an edge of a support, such as a 
table, and a pedestal 2 which is capable of standing on the support and 
which has means for receiving and holding the clamp base 11. 
The clamp base 11 has an upper jaw member which has an upper lever portion 
12a formed with a transversely extending upper jaw portion 13a, and a 
lower jaw member which has a lower lever portion 12b that is pivoted to 
the upper lever portion 12a and that is formed with a transversely 
extending lower jaw portion 13b. As shown in FIG. 1, when the upper and 
lower lever portions 12a, 12b are pressed together, the upper and lower 
jaw portions 13a, 13b are opened and form an opening 111. The upper and 
lower jaw portions 13a, 13b are formed with pads 14 which can provide an 
increased clamping force. 
The pedestal 2 is a hollow cylinder and has a top end 2a, a front end 2b 
and a rear end 2c. The pedestal 2 includes a seat plate 21 which is formed 
below the top end 2a near the front end 2b, a first receiving space 212 
which is formed above the seat plate 21 and which is open at the top end 
2a for receiving the upper jaw portion 13a, and a second receiving space 
213 which is formed below the seat plate 21 for receiving the lower jaw 
portion 13b. The depth of the seat plate 21 from the top end 2a is 
substantially similar to the thickness of the upper jaw portion 13a. The 
upper and lower ends of the seat plate 21 are formed with slots 211 to 
receive the pads 14. A downwardly inclining wall 231 extends from the 
front end 2b below the second receiving space 213 to the rear end 2c of 
the pedestal 2. A third receiving space 23 is confined by the inclining 
wall 231 and a pair of opposing walls 232, 233. The third receiving space 
23 is open at the top end 2a and the rear end 2c of the pedestal 2 for 
receiving the upper and lower lever portions 12a, 12b. The rear open end 
234 is provided for easy access to the third receiving space 23. When the 
lower lever portion 12b is placed on the inclining wall 231, the upper 
lever portion 12a is parallel with the top end 2a (as shown in FIGS. 3 and 
5). A fourth receiving space 22 is formed rearwardly of the seat plate 21 
above the inclining wall 231 and intersects the third receiving space 23. 
As shown in FIGS. 1, 2 and 6, the upper and lower jaw portions 13a, 13b are 
opened by pressing the upper and lower lever portions 12a, 12b. The lower 
jaw portion 13b is first inserted into the fourth receiving space 22 and 
is then caused to pass through the fourth receiving space 22 to enter into 
the second receiving space 213 by turning downwardly the lever portions 
12a, 12b toward the third receiving space 23. Then, the lever portions 
12a, 12b are released so that the upper jaw portion 13a is received in the 
first receiving space 212 and the seat plate 21 is clamped by the upper 
and lower jaw portions 13a, 13b. Meanwhile, the pads 14 engage the slots 
211. When the jaw portions 13a, 13b clamp the seat plate 21, the lever 
portions 12a, 12b are received in the third receiving space 23. The lower 
lever portion 12b is placed on the inclining wall 231 and the upper lever 
portion 12a is parallel with the top end 2a (as shown in FIG. 3). Thus, 
the clamp member 11 can be firmly held in the pedestal 2. 
As best shown in FIGS. 1, 4 and 5, a pair of deep cavities 24 and a pair of 
shallower grooves 25 are formed on two sides of the third receiving space 
23 respectively and are open at their top ends. These cavities and grooves 
24, 25 serve to hold stationery items such as pens, rules, scissors and 
paper clips. 
Referring to FIG. 7 and 8, a second preferred embodiment of the invention 
further includes a reinforcing member 3 for the pedestal 2 in addition to 
the components of the first embodiment as described hereinabove. The 
reinforcing member 3 has a flat bottom 30 and four upwardly projecting 
portions 31 which project from the bottom 30 and which are to be inserted 
into the pedestal 2 via the bottom end of the pedestal 2. Through-holes 32 
are formed in the reinforcing member 3 to be aligned with threaded holes 
26 of the pedestal 2 to load fastening bolts (not shown). The projecting 
portions 31 are provided with weighting blocks (not shown) to stabilize 
the pedestal 2. Although weight is added to the pedestal 2 by means of the 
reinforce member 3 in this embodiment, the invention should not be limited 
thereto. Weight can be added to the pedestal 2 by being directly secured 
to the pedestal 2. 
A third embodiment of the present invention is shown in FIG. 9. The upper 
lever 12a is pivoted to the lower lever 12b by a pin 17 with head portions 
15a which project outwardly of the two sides of the clamp member 11. The 
opposing walls 232, 233 are formed with projecting portions 26 
respectively near the top end 2a of the pedestal 2 for engaging the head 
portions 15a so as to prevent the upper and lower lever portions 12a, 12b 
from being released from the third receiving space 23. 
While the present invention has been described in connection with what is 
considered the most practical and preferred embodiments, it is understood 
that this invention is not limited to the disclosed embodiments but is 
intended to cover various arrangements included within the spirit and 
scope of the broadest interpretations and equivalent arrangements.
