A CHAIN SE-IAPE LAMP
BACKGROUND OF THE INVEN710N
1. Field of the Invention
The present invention relates to a chain shape lamp.
s 2. Description of Prior Art
So far, along with the development of the society, and the improvement of the
people life level, lamp has been used widely. Due the different purposes and
ways in
using, the lamps are made in variety structures and styles. But due to the
complicating
structure being difficult in manufacturing and difficulties of locating the
bulbs and wir-
1 o ing the cord in combination, a chain shape lamp has not came out in the
market yet.

OBJECTS AND SUMMARY OF 7 HE INVENTION
It is therefore a main object of the present invention to provide a chain
shape
lamp that has a simple structure for manufacturing, and easy locating the
bulbs and
wiring the cord in assembling.
For archiving the objects, the present invention provides a chain shape lamp,
which consists of several chain rings stringed together, the said chain rings
hold bulbs
and power cord at inside, and two or more detachable connection portions built
upon the
circumference of the chain ring, the said chain ring also divided into two or
more de-
tachable individual chain ring units; and said chain ring unit is a hollow
tube composed
to by two detachable shells, or one of the said chain ring units is only an
indivisible hollow
tube.
Said chain ring unit has a connection frame on the both ends connecting with
another corresponding chain ring unit.
Said shells composing to said chain ring units have bayonet-coupling frames on
each separately
There are proper number of blocks and retainers built upon the inside of the
chain ring unit, thereby locating the bulbs and wiring the cord.
For facilitating to wire the cord in or out, there is proper number of through-
holes formed on the chain ring unit.
On the places of the chain ring unit around opposite the bulbs, a number of
cooling holes and loopholes are drilled.
A fixed hook and a loop are attached on said chain ring unit designed for
mounting, extending and making up.
For increasing the effect of spotlightiing and decorating, the outside surface
of the
chain ring unit is even attached with amount of small crowning grains.
Some through-holes are pre-set on the outside surface of the chain ring unit
for
inserting transmission ornaments, thereby increasing decoration effect.
Due to adopting above-mentioned structures, the present invention can string
up
a desired number of chain rings together. The feature of the present invention
is to
3o provide a simple structure and easy process of assembling, and convenience
for locating
the bulbs and wiring the cord, and meeting the necessary of large-scale
production.

DETAILED DESCRIPTION OF PRIFERRED EMBODIMENTS
Referring to Fig. 1 to Fig. 4, the present invention comprises several chain
rings
1 stringed up together, therein bulbs 2 and cords 3 are pre-located in the
chain rings 1.
Wherein, two detachable connection portions 21 built upon the circumference of
the chain ring 1, the said chain ring 1 divided into two detachable individual
chain ring
units 22 (referring to Fig. 2 to Fig. 4). Said <:hain ring unit 22 has a
connection frame 23
formed at both ends for connecting with another chain ring unit 22, and
composed by
two detachable shells 11 in table joint. Said shell 11 has proper number of
through-holes
12 for wiring the cord 3 passing in or out, and several bayonet-coupling
frames 24 built
1o upon the proper positions at inside for joining with other shells 1 l, and
some cooling
loopholes 15 and retainers 14 built on opposite the bulbs 2, and several
blocks 13
formed along the rim keeping in a certain distance each other.
For mounting, extending and makin~; up, a loop 17 is formed on the shell 11,
or
a retaining slot 25 is pre-built on the shell 11 for holding a fixing hook 16
in.
In combination, first assemble a chain ring 1 and locating the bulbs 2 and
wiring
the cord 3 at inside in advance. Then saddle a shell 11 of a chain ring unit
22 over a side
of the assembled first chain ring 1, and by means of the connection frames 23
assem-
bling with the shell 11 of other chain ring 'unit 22, a semi-tubular housing
26 is com-
bined, first via the pre-set through-holes 12 ;end the blocks 13 and retainers
14 the bulbs
2 are located on and the cord 3 is wired at the inside of the semi-tubular
housing 26.
Then by means of the bayonet-couplings 24, the other shells 11 co-ordination
to the
semi-tubular housing 26 are spliced together to finish a integrated chain ring
1 stringing
up the first chain ring 1.
Depending on mounting and dressing; design, the present invention provides oth-
er choices, as showing on Fig. 3, therein the shell 11 of the chain ring unit
22 has a loop
17 on the top, and has a retaining slot 25 at t:he bottom. Referring to Fig,
4, in a string of
chain rings 1, the last chain ring 2 is fixed a hook 16 in the retaining slot
25. When ex-
tending the string temporally, the next chain ring can hang on the hook 16
with the loop
17.
3o Referring to Fig. 5, the outside surface of the chain ring 1 can be even
attached
with amount of small crowning grains 18.

CA 02277716 1999-07-12
Referring to Fig. 6, some through-holes 19 are pre-set on the outside surface
of
the chain ring 1 for inserting transmission ornaments 20, thereby increasing
decoration
effect.
Referring to Fig. 7, showing another operation of the present invention, the
dif
ference with the first operation of the present invention is one of the chain
ring units 22
has an indivisible hollow tube without bulbs 2 and cord 22 putting in inside.
On both
ends of said chain ring unit 22, there are twc~ connection frames 23 formed
separately for
joining with another chain ring unit 22. Said another chain ring unit 22 has
connection
frames 23 at connection ends.
1 o In combination, first locate the bulb:. 2 and cord 3 in the shells 11 of
the detach-
able chain ring unit 22 as foregoing described, then close the both shells 11
from the
both sides, meanwhile by means of the connection frames 23 inserting through
the con-
nection frames 23 of said indivisible hollow tube chain ring unit 22, a
integrated chain
ring 1 is assembled. In the same way as last operation, a string of chain
shape lamp is
composed.
