Description

Field of the invention



[0001] The present invention relates in a first aspect to a cord cover for concealing excess cord of an electric male plug. In a second aspect the present invention relates to an electric male plug comprising a cord cover according to the first aspect of the invention. In a third aspect the present invention relates to an electric apparatus comprising an electric male plug according to the first aspect of the invention. In a fourth aspect the present invention relates to a use of the cord cover according to the first aspect of the invention or of a electric male plug according to the second aspect of the invention for an electric apparatus.

Background of the invention



[0002] During the last century it has been common to provide buildings such as homes and offices with sockets for supplying electric voltage to which various electric apparatuses may be connected. Such sockets are usually arranged in the walls of the building.

[0003] Sockets usually comprises two or three holes within which metal bushing are accommodated, which are connected to the grid. Likewise an electric apparatus comprises a connecting cord, one end of which comprises an isolated housing and two or more electrically conducting pins having dimensions that are adapted to the holes in the socket. Hereby, as it is familiar, one may connect an electric apparatus to the grid voltage by arranging the pins of the male plug of the apparatus into the holes in the socket.

[0004] With the view to make electric apparatus flexible as to placement of the apparatus in relation to a socket, such apparatuses are often provided with a relative long cord. Lengths of cords of electric apparatuses of 1.5 meters or more are not uncommon.

[0005] Although such long cords as mentioned provide a certain degree of flexibility as to the distance to the nearest socket to with the apparatus is to be connected, long cords nevertheless may pose some problems.

[0006] These problems especially manifest themselves in instances in which it is desired to connect an electric apparatus to a socket which is in immediate vicinity of an electric socket. In such situations a relatively long cord will be in the way and represent an unattractive appearance,

[0007] Excess cord will thereby be aesthetically undesirably and will also be able to represent a safety hazard in that one's movements unintentionally could grab the excess cord whereby one may fall or whereby the electric apparatus may tip over.

[0008] Additionally, loose excess cord may pose to be a hygienic problem in that such a cord is an element that has a tendency to attract dust and grease.

[0009] The same problems are present in case it is desired to connect the electric male plug to the socket via an extension cord or an electric power distributing socket.

[0010] In order to solve this problem FR 2 711 017 discloses a wire storage box. This wire storage box comprises a box having a lid to be mounted on the box. The box furthermore comprises a cut-out into which a cord may be arranged. Moreover, the box on one of its surfaces comprises one or more holes, into which a bushing may be arranged. This bushing extends from that surface and comprises holes which are adapted to an electric male plug in a way that when the bushing is arranged in the associated hole in the box, a plug can be led into the box and further into the interior of the bushing and the pin of the male plug may subsequently be led through the holes in the bushing itself and hereafter the electric plug with the associated wire storage box can be arranged into a socket. The cord is arranged in the cut-out of the box. The interior of the box is large enough for winding up a certain length of cord and thereby the cord of an electric apparatus may be adapted to the desired length, when the male plug of the apparatus is arranged into the box and the bushing as described above.

[0011] The wire storage box disclosed in FR 2 711 017 has the disadvantage that it is rather large and clumsy and not suitable for the type of sockets which comprise a depression into which an electric plug may be arranged and which thereby will surround the housing of the plug.

[0012] Moreover, the presence of the loose bushing, into which the electric male plug is to be arranged, a certain degree of instability results, in the sense that the bushing may fall out whereby the functionality of the wire storage box is lost.

[0013] Additionally, the cut-out, through which the wire is being led, implies inflexibility limitations as to in which orientation the cord is entered into the box, because the wire storage box in FR 2 711 017 only allows one orientation due to the fixed cut-out.

[0014] Moreover it will not be possible to insert the wire storage box of FR 2 711 017 in an electric female sockets having a switch or with certain specific deep arrangement or designs.

[0015] Accordingly, a need exists for an improved cord cover for concealing cords of electric apparatuses.

[0016] It is an objective of the present invention to provide such a cord cover.

Brief description of the invention



[0017] This objective is achieved according to the present invention in its first, second, third and fourth aspect, respectively.

[0018] Accordingly, according to the first aspect of the invention a cord cover for concealing excess cord of an electric male plug is provided, wherein the cord cover comprises:
  • a tubular element having a first axial end and a second axial end;
  • an end closure element;

wherein the tubular element at its first axial end comprises an end surface;

[0075] Referring now to the figures in order to illustrate the present invention, Fig. 1a illustrates in a cross-sectional view a principle diagram of a cord cover according to the first aspect of the present invention.

[0076] Fig. 1a shows the cord cover 100 for concealing excess cord 2 of an electric male plug.

[0077] The cord cover 100 comprises a tubular element 4 having a first axial end 6 and a second axial end 8 along with an end closure element 10.

[0078] The tubular element 4 comprises at its first axial end 6 an end surface 12 and comprises at its second axial end of the tubular element 4 an opening 14.

[0079] The geometry and the dimensions of the opening 14 of the second axial end 8 of the tubular element 4 is adapted to the geometry and the dimensions of the end closure element 10 in such a way that the end closure element 10 may be held in place in the opening 14 of the second axial end 8 of the tubular element 4.

[0080] This holding in place is brought about via friction, in that it is seen that the second axial end 8 of the tubular element 4 comprises a first set of engagement means 32 and that the end closure element 10 comprises a second set of engagement means 34; whererin the first set of engagement means 32 are being configured to enter into engagement with the second set of engagement means 34 and hold these two engagement means together via friction.

[0081] It is also seen in Fig. 1a that the end surface 12 at the first axial end 6 of the tubular element 4 comprises two holes 16a,16b for accommodating two pins 18a,18b of a male plug.

[0082] Also seen in Fig. 1a is that the interior 22 of the tubular element 4 defines a cavity 22 which thereby may accommodate excess cord 2 of an electric male plug, when the pins 18a,18b of the electric male plug 20, attached to cord 2, has been led through the holes 16a, 16b at the end surface 12 of the tubular element 4.

[0083] As the tubular element 4 at its first axial end 6 is having a maximum outer extension in a direction perpendicular to the axial direction of maximum 40 mm, the tubular element may be arranged in any type of electric socket or electric distribution socket.

[0084] Fig. 1c shows a plan view a drawing of an electric male plug 20 having two electric pins 18a, 18b and an associated cord. The male plug 20 is intended for being accommodated in the interior 22 of the tubular element 4.

[0085] Now returning to Fig. 1a, it is also seen that the cavity 22 in the interior of the tubular element 4 comprises a duct 28 which via friction may hold an electric male plug in place, when being accommodated in the interior 22 of the tubular element and when the pins 18a,18b of the male plug have been led through the holes 16a,16b at the end surface 12 of the tubular element 4.

[0086] Fastening means 24 in the form of a screw 26 enables squeezing of the male plug 20 in the duct 28. The screw hole 29 makes it possible to reach the screw 26 with a screw driver.

[0087] Fig. 1a moreover shows that the end closure element 10 at a rim thereof comprises a recess 30 for accommodating the cord 2.

[0088] Fig. 1b illustrates in a cross-sectional view a principle diagram of an alternative design of the cord cover illustrated in Fig. 1a.

[0089] Comparing the embodiment shown in Fig. 1b with that of Fig. 1a reveals that the individual holes 16a,16b for each of the two or more pins 18a,18b as shown in in Fig. 1a has been converted into a common hole 16 which is configured to accommodate both pins 18a,18b of the male plug illustrated in Fig. 1c. The common hole 16 is arranged at the surface 12 of the first end 6 of the tubular element 4 in that the surface of the first end 6 now comprises the rim of the tubular element 4 and the end surface of the duct 28.

[0090] Fig. 2 is a principle diagram showing in a cross-sectional view the working mode of the cord cover of Fig. 1a.

[0091] Fig. 2 shows the electric male plug of Fig. 1c which has been accommodated in the cavity 22 in the interior of the tubular element 4 and that the male plug is arranged in the duct 28. Part of the cord 2 has been winded and concealed in the interior 22 of the tubular element 4. The end closure element 10 is via friction held in place in the second axial end of the tubular element 4.

[0092] Hereby the cord cover 100 enables concealing excess cord 2.

[0093] It is seen that part of the cord 2, appearing inside the tubular element can be winded around the electric male plug 20.

[0094] Fig. 3 is a principle diagram showing in a cross-sectional view the design of an electric male plug according to the second aspect of the present invention.

[0095] Fig. 3 shows the male plug 200 comprising a cord cover 100 according to the first aspect of the present invention. In addition, the male plug comprises two electric pins 38a,38b along with an electric cord 2 which in turn comprises two leads 40a,40b.

[0096] It is seen that in respect of the two holes 16a,16b at the end surface 12 of the tubular element 4, each hole has been provided with one of these electrically conducting pins 38a,38b.

[0097] Besides, the two electrically conducting pins 38a,38b are each electrically connected to its own individual electrical lead 40a,40b at one end of the electric cord 2 and the two electrically conducting pins 38a,38b are each being fixated in its respective hole 16a,16b at the end surface 12 of the cord cover 100.

[0098] Further, the two electrically conducting pins 38a,38b at the end thereof which appear in the interior of the tubular element are electrically insulated from the surroundings by being encapsulated.

[0099] It is also seen in Fig. 3 that the tubular element 4 in its interior comprises a winding element 36 in the form of an axially arranged rod which is mounted to the part of the tubular element which defines the end surface 12. The winding element 36 can be used for winding excess cod within the interior 22 of the tubular element 4 (not shown in Fig. 3).

[0100] The male plug 200 thereby functions as a traditionally male plug for insertion into a socket or an electric power distribution socket while also enabling concealing excess cord.

[0101] Fig. 4 is a principle diagram showing in a cross-sectional view the design of an electric male plug according to the second aspect of the present invention.

[0102] Fig. 4 shows the electric male plug 200 according to the second aspect of the present invention, wherein the winding element 36 is being connected to the end closure element 10 and also being displaceable in an axial direction. This will make winding of excess cord easier.

[0103] Fig. 4 also shows that the electric male plug comprises a safety stop 56 which secures that upon pulling the cord 2, the pins 38a,38b will not be pulled out of their respective holes 16a,16b.

[0104] Fig. 5 is a principle diagram showing in a cross-sectional view the design of an electric male plug according to a special embodiment of the second aspect of the present invention.

[0105] Fig. 5 shows an electric male plug 200 according to the second aspect of the present invention, wherein the winding element 36 comprises a first axial end 42 and a second axial end 44, wherein the first axial end 42 of the winding element is being arranged nearest to the first axial end 6, of the tubular element 4, and wherein the second axial end 44 of the winding element is being arranged nearest to the second axial end 8 of the tubular element 4.

[0106] The first axial end 42 of the winding element 36 comprises an end part 46, where the electric pins 38a,38b are arranged in this end part.

[0107] Once again it is seen that the winding element 36 is being connected to the end closure element 10.

[0108] The first axial end 6 of the tubular element defines an opening 48; wherein the geometry and the dimensions of this opening 48 on the one hand and the geometry and the dimensions of the end part 46 of the winding element 36 on the other hand are adapted to each other in such a way that this end part 46 can be accommodated in this opening 48, in that the end part 46 of the winding element 36 thereby becomes part of the end surface 12 of the tubular element 4, when the winding element 36 has been displaced all the way up to the first axial end 6 of the tubular element 4.

[0109] Hereby is achieved that the winding element 36 may be pulled a relatively long distance out of the tubular element 4, whereby a tight winding of the cord 2 and thereby winding of a greater length of cord 2 is possible.

[0110] Viewing Fig. 5 it is easily acknowledged that the surface 12a of the end part 46 in combination with the partial surface 12 of the tubular element in combination will form an end closure of the tubular element 4 of the electric male plug, when the end part 46 is being displaced all the way up to the first axial end 6 of the tubular element 4.

[0111] The male plug 200 in Fig. 5 comprises locking means 50 in the form of a screw 52 for locking the position of the end part 46 in relation to the rest of the tubular element 4, when the end part 46 has been displaced all the way up to the first axial end 6 of the tubular element 4.

[0112] It is to be noted that in the figures it has not been intended to illustrate made-to-scale and mutually correct dimensions of the individual elements of the inventions. In contrast it has merely been the intention to illustrate the principles of the present invention.
