Description
FIELD OF THE INVENTION
[0001] The invention relates to a storage device for cables more
particular a storage device for domestic application
BACKGROUND OF THE INVENTION
[0002] Storage devices for cables are known. A particular
commercially successful storage device comprises two opposite
flange parts connected by a separate intermediate connection part.
The intermediate connection part functions as reel for winding the
cable while the flange part, having a relatively large dimension,
function to fully enclose the cable. The flange parts are made from
a deformable material and biassed to a comb shape. The dimensions
of the comb and the length of the intermediate connection part are
such that the extremities of the flange parts attach each other if
no cable is present.
[0003] Although commercially successful, it is difficult to obtain
such cable storage devices. Assembly is complicated. For assembly
it would be advantageous if the separate intermediate connection
part could be easily brought into engagement with both flange
parts. However, this would also mean that it would be relatively
easy for the user to separate the flange part from the intermediate
connecting part. This is not desirable and because of that there is
a very tight fit between the intermediate part and the flange part.
In contrast to the flange part, the intermediate part is made from
a rigid polymer material.
[0004] At the connection between the connection part and the flange
part, the flange part should be thickened to obtain sufficient
strength to be clamped around the connection part. This means that
additional plastic material is used and the thickness at the centre
of the storage is "double" i.e. comprises the intermediate part
overlayed by the thickened flange part.
[0005] The invention aims to provide a storage device which can
easily be produced and preferably be produced in one step by
injection moulding.
[0006] It is a further aim of the invention to provide a storage
device which has a larger storage capacity at the same outer
dimensions.
[0007] It is a yet further aim of the invention to provide a
storage device comprising less plastic material.
[0008] It is another aim of the subject invention to provide a
storage device made from plastic materials which are usual in the
art.
[0009] A further aim of the invention is to provide a storage
device wherein the connection between the connection part and the
flange part is ensured under all circumstances.
SUMMARY OF THE INVENTION
[0010] According to one aspect of the invention, a storage device
for a cable is provided comprising two spaced flange parts
connected by an intermediate connecting part, wherein said
connecting part and said flange part are integrally moulded.
[0011] According to a further aspect of the invention the flange
parts are comb shaped and have two stable positions, the first
position in which the cavity of the comb is directed to the opposed
flange part and a second position in which the cavity of the comb
is directed away from the opposed flange part.
[0012] According to a further aspect of the invention, the flange
parts and the connection part comprise an elastomeric plastic
material.
[0013] According to a further aspect of the invention one of said
flange parts is provided with a recess at its circumference.
[0014] According to a further aspect of the invention one of said
flange parts comprises a circumferential bead.
[0015] According to a further aspect of the invention the storage
device is realized in a one step by injection moulding.
BRIEF DESCRIPTION OF THE DRAWINGS
[0016] FIG. 1 is a perspective view of a preferred embodiment of
the invention in a first position and having a cut out for
elucidation purposes;
[0017] FIG. 2 is the storage device according to FIG. 1 in a second
position.
DETAILED DESCRIPTION OF THE INVENTION
[0018] In FIGS. 1 and 2 a preferred embodiment of the invention is
shown. The storage is generally referred to by 1 and comprises two
flange parts 2 and 3. These flange parts are integrally moulded to
a connection part 4. As is clear from FIGS. 1 and 2 the flange
parts have a comb shape. Two stable positions can be obtained, the
first position shown in FIG. 1 which is the position of use wherein
the circumferential edges having a bead 5 are directed towards each
other. A recess 6 is provided as outlet/inlet for cable 7.
[0019] FIG. 2 shows the second stable position in which the flanges
are moved away from each other i.e. the combs defined by the
flanges are in opposite directions. This is the position of
moulding. I.e. if the storage according to the invention, is
produced by injection moulding, which is presently preferred, it
will leave the mould in the condition as shown in FIG. 2. By simply
bringing the circumferential edges of the flange parts 2, 3
together, the storage device will flip into the second stable
position thereof and the device according to FIG. 1 will be
obtained.
[0020] According to the invention the connection part 4 is
integrally moulded with flange parts 2 and 3. This obviates later
assembly of the flange parts 2 and 3 with the connection part 4.
Furthermore a very secure connection between connection part 4 and
flange part 2 and 3 can be obtained whilst a relatively limited
amount of plastic material is used. Because of integrally moulding
flange parts 2 and 3 to connection part 4, these flange parts do
not have to be thickened adjacent to the connection part as in the
prior art meaning that the storage capacity increases.
[0021] In this prior art storage each of the flange parts are
provided with a sleeve to be arranged around an intermediate
connection part. The sleeve ends of both flange parts abut each
other in the assembled condition. This means that in the assembled
condition the core is realized by an outer sleeve comprising to
sleeve halves of the flange parts and an inner sleeve comprising
the connection part. Both sleeves should be relatively thick to
obtain sufficient strength a stability of the structure. This means
that at the same outward dimensions of the inventive storage device
more cable volume can be received.
[0022] By adjusting tie thickness of the connection part the
stiffness of the storage device can be easily controlled. It is not
longer necessary to take other design features in considerations
such as the requirement of a secure connection between the
connection part and the flanges 2 and 3.
[0023] The storage 1 is preferably injection moulded from an
elastomeric plastic material.
[0024] Because of integrally moulding connection part 4 and flanges
2 and 3 the design adjacent to the transition between connection
part 4 and flanges 2 and 3 can be changed with regard to the prior
art designs. More particular the curvature of the flanges can
increase allowing for a further increase in the volume.
[0025] In a further embodiment (not shown) connection part 4 can be
solid i.e. the ends of both flange parts 2 and 3 can be closed.
This means that no longer there is a central opening extending from
flange part 2 to flange part 3 but each of the flanges is a
smoothly curved item.
[0026] Although the invention has been disclosed referring to a
preferred embodiment, it will be immediately clear for the person
skilled in the art that alternatives are possible within the range
of the appended claims.
