ABSTRACT:

TECHNICAL FIELD
The present invention is related to the improvement of the fixture construction of the retractable suitcase handle.
BACKGROUND ART
In
FIG. 4
the outside of a common and normal suitcase
5
with a fixed retractable handle
60
is shown, where the handle
60
is halfway retracted.
The handle
60
is formed by two rods
61
of fixed length, whose upper tips are linked by a grip
62
.
As for the handle
60
, the suitcase
50
is divided into two parts, the body part
51
and the cover part
52
, on the base wall &agr; (suitcase wall) of cover part
52
the handle
60
is mounted as shown in FIG.
3
.
The inside of the base wall &agr; is as follows: in order to allow the rods
62
to be retracted freely, two storage tubes
63
are fitted parallel on the longitude, both the upper and lower ends of these tubes, are fixed onto the base wall &agr; by upper fixture construction
64
and lower fixture construction
65
respectively.
Therefore as shown in
FIG. 3
, the storage tubes
63
usually extended to the whole length of the base wall.
But the body part
51
is naturally built strong enough to withstand some rough handling. Therefore the storage tubes
63
, which are built into the base wall &agr; do not really need to serve as a reinforcement of the suitcase
50
.
Also for all users it is sufficient enough if the length of the rods
61
when they are completely extracted from the storage tubes
63
, reaches half of the length of base wall &agr;.
In short, in a normal suitcase
50
, the length measurements of the storage tubes
63
are unnecessarily long.
Therefore this part, which is meaningless and raises the production costs and the weight of the suitcase and reduces its effective inside capacity.
So the aim of this invention is to reduce the length of the rods of the retractable handle and the storage tubes as much as possible to avoid unnecessary production costs and weight as well as the reduction of effective inside capacity and so we present this fixture construction suitcase handle.
In order to accomplish the above mentioned aim, the built in construction suitcase handle is characterized by the retractable that can easily be stored into the storage tubes which are attached to suitcase wall and that the length of the above mentioned storage tubes is shorter than the length of the above mentioned suitcase wall.
The length of the storage tubes should be between ⅔ and ⅓ of the length of the suitcase wall.
Also the place where the lower part of the storage tubes is fixed to the synthetic resin suitcase wall is best formed at the same time the wall is made.
