ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to the Christmas lights and more particularly to a tubular string of the Christmas lights which is convenient to manufacture and can be cut into different length to cope with the requirement of the user.
Previously, people dried to dispose one or several strings of the Christmas lights into a transparent hose to form a tubular string of the Christmas lights in order to protect the lights from external water or damagement. However, if any one of the lights inside the hose is damaged, the whole string of the lights may be failed and is difficult to repair. A typical tubular string of the Christmas lights
10
is therefore available as shown in
FIGS. 1
to
3
. This type of the Christmas lights comprises a transparent hose
11
, an arcuate strip
12
disposed into the hose
11
, two bunches of copper wires
13
and
14
integral with the arcuate strip
12
and parallel extending along the length of the strip
12
, a plurality of the Christmas lights
15
and
16
spacedly disposed into the hose
11
and alternately connected with the single wires
131
from the bunch
13
or
141
from the bunch
14
, a plurality of intermediate wires
151
and
161
which connect the lights
15
and
16
into a string, a plug
17
connected to one end of the hole
11
having a pair of blades
171
and
172
respectively engageable with the bunches of wires
13
and
14
and a socket
18
connected to the other end of the hose
11
having a pair of outlet respectively engageable with the bunch of wires
13
and
14
.
This type of tubular string of the Christmas lights has an advantage that it can be cut into different length to cope with the requirement of the site to which it decorates. However, it has also a great disadvantage of difficulty to manufacture. Because, the single wires
131
and
141
must be regularly drawn away from inside the areuate strip
12
and then welded with lights respectively this job is very wearisome and wastes time and manpower.
SUMMARY OF THE PRESENT INVENTION
The present invention has a main object to provide a tubular string of the Christmas lights which is readily to manufacture.
Another object of the present invention is to provide a tubular string of the Christmas lights which can be cut into different length to cope with the site to which it decorates.
Further object of the present invention is to provide a tubular string of the Christmas lights which the hose can be variable to provide versatility to the user.
The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.
