SIMPLIFIED CONNECTING STRUCTURE OF A CURTAIN-TYPE LIGHTING STRING

STRUCTURE DE RACCORDEMENT SIMPLIFIEE D'UNE GUIRLANDE ELECTRIQUE DE TYPE RIDEAU

English Abstract

The present invention relates to a simplified connecting structure of
a curtain-type lighting string, which includes a main wire and several
separated strings thereon. A bypassed wire is provided between every
two nearby string instead of the upward connecting wire and connects
both ends respectively with a bottom bulb of both strings. So the
needed amount of the connecting wire will be reduced and the assembly
of the lighting strings becomes more convenient and simple.

Claims

What is claimed is:
1. A simplified connecting structure of a curtain-type lighting
string including a main wire and several separated strings
thereon, and the characteristic is that a bypassed wire being
provided between every two nearby string instead of the upward
connecting wire and connecting both ends respectively with a
bottom bulb of both strings.

TITLE: Simplified Connecting Structure of a Curtain-type Lighting
String
BACKGROUND OF THE INVENTION
A curtain-type lighting string is popular in these days, which
includes several separated strings having a equal length or a different
total length as shown in figures 1, 3, and 5. The conventional curtain-
type lighting string, for example in figure 1, is provided with a basic
wire (b) and a connecting wire (a) becoming a first string ( 1 ). The
connecting wire (a) exi:ends from a bottom bulb ( 19) back to near the
main wire (b) and then connects to a first bulb (21) of the second string
(2). During the same procedures as above, a curtain-type lighting
string is completed. In this structure, it is known that long connecting
wire (a) will be needed and the manufacture or assembly of the lighting
string is more difficult. Figure 3 shows a similar curtain-type lighting
string to figure 1, which includes an end socket (d) thereof. Figure 5
shows another curtain-type lighting string, which has the lighting
strings with a different length, wherein a different symbol indicates a
different connecting bulb series. Both lighting strings in figures 3 and
5 need a large amount of the connecting wire.
In view of the above problems, the primary object of the invention
is to provide a simplified connecting structure of the curtain-type
lighting string in order to overcome prior known drawbacks. Now the
features and advantages of the present invention will be described in
detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to figure 2 firstly, it can be seen that it is an
improvement of the prior structure of figure 1. A bypassed wire (c) is
provided to connect one end with the end bulb ( 19) of the first string
( 1 ) and the other end with an end bulb (29) of the second string (2),
which is then connected with the connecting wire (a). The bypassed
wire (c) is provided between every two nearby strings parallel. So the
used amount of the connecting wire (a) is obviously reduced and the
connection or assembly of the lighting string is simplified.
Figure 4 shows an improved structure only having an end socket (d)
relating to figure 3 and has a same effect of simplified connection as
well as less need of the connecting wire. When the application
according to the present invention is practiced on a curtain-type
lighting string with a different length of the strings, please referring to

CA 02300767 2000-03-16
figures 5 and 6, it will be described as following for example by the O-
symbol string. In figure 6, it can be found that a bypassed wire is also
provided to connect it~c one end with an end bulb of a fore string and
the other end with a bulb at a parallel position of a rear string. So the
needed amount of connecting wire of figure 6 according to the
invention is less than of the prior design of figure 5, while the
assembly of figure 6 becomes more convenient than before.
Accordingly, the present invention provides a simplified connecting
structure of a curtain-type lighting string for reducing the needed
amount of the connecting wire and simplifying the assembly of the
lighting string. And pit has excellent practical value in the field.
Evidently the invention is thus allowable for patent.
