Abstract

The invention relates to a headset (1) for a vehicle with a handset (2) and a support (4) for the handset (2), the handset (2) being connected to the support (4) via a coiled cable (3) is. The aim here is to prevent the spiral cable (3) from having a disruptive effect and / or from being damaged when the handset (2) is in place.

Description

The invention relates to a speaking device according to the preamble of patent claim 1.

In vehicles, public address systems are regularly located near or next to a seat. For telephoning the handset, which is connected via a spiral cable with other electrical components of the headset, be removed from a support. During a telephone conversation, the spiral cable is in the stretched state and bridges the distance between the support and the handset. In the attached state of the handset, the spiral cable contracts and lies between the handset and the recording.

Such arrangements have the disadvantage that the spiral cable remains lying, for example, on the seat surface of the secondary seat. In such a situation, the handset can only be moved freely again when a person who has taken place in the secondary seat releases the spiral cable again. Furthermore, vehicle headset systems are increasingly being integrated into center consoles or other trays to accommodate them in a protected manner and to avoid injury from protruding components in the event of accidents. In the known headset devices that are integrated into such recordings, it happens regularly that the spiral cable hangs over the receptacle in the on-hook state of the handset. In this state, the spiral cable is particularly susceptible to damage because it may be damaged by, for example, a briefcase set up on the tray. Furthermore, when shooting, which are also provided with a cover, often a "replenishment" of the spiral cable in the recording required so that it can be closed.

From the DE 38 43 817 C1 a headset for a vehicle with a handset and a support for the handset is known, wherein the handset is connected to the support via a spiral cable and the support has a receiving space for almost complete reception of the spiral cable in the on-hook state of the handset. However, such headset devices are not suitable for installation under - often prevalent in a vehicle - cramped space.

The invention has for its object to develop a headset of the type described above, which causes the spiral cable in the on-hook state of the handset does not interfere and is arranged so that it can not be damaged, the headset for installation in a narrow receiving shaft should be suitable.

This object is achieved in conjunction with the preamble of claim 1 according to the invention by the characterizing features of claim 1.

The headset according to the invention has a support with a receiving space for almost complete recording of the spiral cable in the on-hook state of the handset. The spiral cable is then taken up in the recording except for a small portion that leads from the handset to the recording, so that it is not disturbing in the vehicle interior.

An advantageous embodiment of the subject invention provides that the receiving space is designed as a U-shaped receiving space. In this way, a wide recording space is optimally used for recording.

According to a particular embodiment of the subject invention, the audio device has a receiving space, which is arranged under the support, wherein the support and the receiving space form a receiving box.

By this arrangement it is achieved that the headset can be installed easily in installation slots, which have only a small cross-sectional area, since the spiral cable next to the handset requires almost no additional area.

Furthermore, it is advantageous if the receiving box has a cable inlet and an outlet holding the spiral cable. Such a cable box forms together with the spiral cable a complete functional unit, which can be retrofitted and / or used as an additional component.

It is of particular advantage if the U-shaped channel has an inner wall, which is formed in the region of the bend as a rotatably mounted rolling elements. In such a channel designed the frictional resistance, which experiences the spiral cable at the bend of the inner wall, is particularly low, since the inner wall moves when stretching or contraction of the spiral cable with this.

It is of particular advantage if the spiral cable has a PU sheath, the receiving box is made of PC-ABS and the rolling body has at least one surface of POM. By this pairings of materials a slight sliding of the spiral cable on the surfaces of the receiving box is possible.

Furthermore, it is advantageous if the spiral cable has a round cross section. Thus, hooking of the spiral cable is effectively prevented.

It is of particular advantage if the contraction of the spiral cable is reinforced by a return means connected to the spiral cable. In this way, a quick and complete retraction of the spiral cable is favored.

An expedient embodiment of the subject invention provides to provide an expandable thread within the turns of the spiral cable, which is connected at several points with the spiral cable. In this way, the retraction of the spiral cable is supported along its entire length.

Furthermore, it is advantageous to provide the spiral cable with a pointing away from the longitudinal direction of the cable web. By such a web, the coefficient of friction of the cable is kept particularly low because the cable rubs only with a very small contact surface on the surface of the receiving box.

An expedient embodiment of the subject invention provides to arrange the U-shaped cable channel in a horizontal plane. This arrangement allows a flat structure of the receiving box, which corresponds approximately to the claimed by the applied handset surface.

Finally, a further embodiment of the subject invention provides to lead the spiral cable vertically into the receiving space. As a result, the force of gravity acts as a support when returning the spiral cable.

A provided at the shaft entrance roller-like wall and / or rotatable roller causes a low friction between the spiral cable and the wall, even if the Sprialkabel at an acute angle to the bottom of the receiving space on or is pulled out.

It is advantageous if the support is rotatably or liftably arranged on the receiving space, as this the handset can be better grasped when the support is in a narrow receiving shaft.

A pivoting of the support by means of a spring mechanism makes the construction particularly user-friendly and cost-effective.

The wall 23 is as a roller-shaped deflection 30 formed, extending to a bottom 4b the edition 4 extends (see 4 ). According to an embodiment of the subject invention, not shown, the wall is 23 formed as a rotatable roller whose axis of rotation is parallel to its longitudinal direction. According to a further embodiment variant, the rotatable roller consists of at least two individual rollers. The edition 4 is about a band 40 rotatable with the receiving space 17 connected. The ribbon 40 is by two at the pad 4 molded side bearings 41 . 42 (see also 4 ) and one at the recording room 17 molded center bearing 43 educated. The side bearings 41 . 42 and the center camp 43 be through a bearing pin 44 (symbolically represented by a dash-dot line) connected. To mount the tape is the bearing pin 44 through one in the wall 22 executed drilling 45 inserted. According to an advantageous variant of the subject invention, not shown, is the band 40 designed as a film hinge, that is the edition 4 and the recording room 17 can be produced as a one-piece injection-molded part. The recording room 17 has side walls 46 , On the side walls 46 are recesses 47 formed. These recesses 47 form receptacles for locking lugs, which are integrally formed on a drive slot, not shown, in particular in a center console, not shown. With the help of the recesses 47 can the recording box 16 easy, fast and without tools in the mentioned drive bay can be mounted by simply pressing. According to an embodiment not shown, alternatively or additionally, a screw connection of the receiving box 16 provided with the center console. In a border area 48 the edition 4 is the edition 4 prepared for the inclusion of a button, not shown. The button is in holes 49 . 50 mounted and lowered and engages with a plunger (not shown) through a rectangular recess 51 , With this plunger, he actuates one at the bottom 4b the edition 4 arranged linkage, which on a locking mechanism 52 that works in the recording room 17 is arranged (see 3 ). In this locking mechanism 52 snaps the pad 4 with a projection, not shown. By releasing the locking mechanism 52 with the help of the button and the linkage is the edition 4 through one between the domes 53 . 54 (please refer 3 . 4 ) arranged spring, not shown around the bearing pin 44 relative to the recording room 17 turned. The angle of rotation around which the overlay 4 turns, is about 10 ° to 15 °. According to an embodiment of the subject invention, not shown, it is provided between the support 4 and the recording room 17 To provide attenuators, which the pad 4 during start-up and / or lowering in their motion dampen and so create a "soft" movement dynamics.

3 shows a simplified representation of the recording room 17 according to 1 and 2 in perspective view. The recording room 17 is as a tub-shaped shell 60 educated. In a tub area 61 with a tub bottom 61a is a middle area 62 formed by a U-shaped channel 63 is surrounded. The U-shaped channel 63 consists of end areas 64 . 65 and a curve area 66 , The end areas 64 . 65 are through the side walls 46 and guide walls 67 limited. The curve area 66 is through sidewalls 64 and a rotatable rolling element 68 limited. The rolling element 68 is about an axis 69 rotatable, perpendicular to the bottom of the tub 61a stands. Furthermore, in the wall 46 near the end area 65 a passage 70 executed by the spiral cable 3 (shown here for convenience as a dashed line) the receiving space 17 can be fed. The spiral cable 3 runs from the end area 65 in the curve area 66 and then in the end area 64 where there is the recording room 17 by the one in the edition 4 (please refer 2 ) designed shaft 21 to the handset 2 leaves. In the passage 70 is the spiral cable 3 For example, fixed immovably by a molded spout, not shown. The U-shaped channel 63 has a length L which is slightly smaller than a length S (not shown), which is the spiral cable 3 in the contracted state between the passage 70 and the cable feed 13 (please refer 1 ) occupies. In other words, the length S corresponds to the spiral cable 3 in the contracted state, the length L of the U-shaped channel 63 plus a cable section of about 5 cm, the spiral cable 3 needed to keep the distance between the shaft 21 and the cable feed 13 to bridge in the unstressed state with the handset on. In the on-hook state of the handset 2 on the edition 4 lies the spiral cable 3 in a relaxed or almost relaxed state between passage 70 and the cable feed 13 , Now the handset 2 from the edition 4 removed, then the spiral cable 3 between the passage 70 and the cable feed 13 curious; excited. This extends the spiral cable 3 so that it gets longer and the individual turns 3a in the U-shaped channel 63 to start moving. That is, the spiral cable 13 or the turns 3a slip in the U-shaped channel 63 along the tub floor 61a , the side walls 46 and the guide walls 47 in Arrow direction P to the shaft 21 out. In the curve area 66 puts the spiral cable due to the prevailing tensile stress in the rolling elements 68 and turns it in the direction of arrow P 'about the axis 69 , Thus, in the curve area 66 almost no slippage of the spiral cable 3 required, but there is a virtually no force requiring transport / rotational movement of the spiral cable 3 or the rolling element 68 , As a result of the sliding and walking movement of the spiral cable 3 in the direction of arrow P, more and more turns gradually appear 3a from the shaft 21 and allow the handset 2 correspondingly far from the receiving box 15 to remove. The emergence of the spiral cable 3 from the shaft 21 is through the in 2 described training of the walls 22 to 25 favors because there are no edges where the spiral cable imposed or subject to increased sliding friction. When hanging up the handset 2 on the edition 4 pulls the spiral cable 3 because of him in between the passage 70 and the cable feed 13 existing tension together. In the area of the U-shaped canal 63 the contraction of the spiral cable takes place 3 opposite to the direction of the arrow P. It is irrelevant from which spatial position of the handset 2 for circulation 4 is returned because the spiral cable 3 on all walls 22 - 25 without a strong bend through the shaft 21 in the U-shaped channel 63 to be led. When contracting the spiral cable 3 the transport / rotational movement of the rolling element takes place 68 against the rotation indicated by the arrow P '. Thus lies the spiral cable 3 at least a short time after hanging up the handset 2 on the edition 4 again in the relaxed or almost relaxed state in the U-shaped channel 63 ,

The edition 72 and the recording room 73 are rotatable about a joint 74 connected with each other. At the pad 72 is a recording 75 for a spring 76 formed. This is a counter record 77 for the spring 76 across from. The counter-admission 77 is at the recording room 73 formed. Furthermore, the edition 72 a locking means 78 on that for engaging in a recording room 73 trained counter-locking means 79 is provided. The receiving box 71 is from a closed position A, not shown, of the receiving box 71 in the open position B in the direction of arrow C movable. In position A is the edition 72 all over the recording room 73 on, the spring 76 is between the recording 75 and the counter-admission 77 clamped and the locking means 78 sits in the counter-catch 79 , By pressing an unlocking button, not shown, the cohesion of the locking means 78 . 79 solved and the edition 72 move to position B. Components in which the receiving box 71 not from the receiving box 16 are different, are with the same reference numerals as in the receiving box 16 shown.

6 shows a simplified schematic representation of another receiving box 105 , With dashed lines here are sidewalls 100 . 101 and a back wall 102 a center console 103 shown. Between the side walls 100 . 101 is a recording room 104 the receiving box 105 on locking lugs 106 attached. One to the receiving box 105 belonging edition 107 is about springs 108 that in guides 108a . 108b are held, with the recording room 104 connected. With the help of a locking / unlocking mechanism, not shown, it is possible, the edition 107 in a low position A 'at the receiving space 104 set. Furthermore, it is possible the edition 107 from the lowered position A 'by the latch / Endrastmechanismus to solve. This is then from the springs 108 raised to a raised position B '. In the illustrated view it is clear that an unillustrated handset in the raised position B 'is easily accessible without the center console 103 disturbing. In the low position A, however, the handset, not shown, is protected between the walls 100 . 101 . 102 the center console 103 arranged. A return of the edition 107 in the position A 'is done by depressing the support 107 down to the recording room 104 , In this position, the locking / Entrastmechsnismus not shown engages again and keeps the support 107 in position A '. A depression of the pad 107 is also possible with the pads of the handset, not shown. According to an embodiment variant, not shown, the latching / Entrastmechasnismus is designed so that the support is locked in the raised position and / or automatically depressible at the touch of a button. Components in which the receiving box 105 not from the receiving box 16 are different, are with the same reference numerals as in the receiving box 16 shown. According to an embodiment variant, not shown, it is provided to cover the receiving space by a cover plate provided between it and the support, which has an opening in the region of the shaft. Another variant, not shown, provides that the arranged in the receiving box partitions and / or rollers are telescopically apart, so that the areas formed in the receiving box areas remain separated when moving apart of support and receiving space. In particular, in provided in this case, form the walls and / or rollers on the underside of the support and the receiving space, which are adjacent to each other in the contracted state of the receiving box.

7 shows a representation of a spiral cable 110 , The spiral cable 110 has an outward rib 111 on. The rib 111 serves for the sliding friction between a wall 112 and the spiral cable 110 to keep low.

The invention is not limited to illustrated or described embodiments. Rather, it includes developments of the invention within the scope of the patent claims. In particular, the invention also provides to arrange the U-shaped cable guide parallel to a vertical plane.

According to a further embodiment of the invention, not shown, it is provided to provide the spiral cable in at least two subregions with different winding diameters. In this case, a particularly preferred embodiment provides for providing the spiral cable in a first section with a winding diameter which is smaller than the winding diameter of the spiral cable in a second section. The length of the first section is dimensioned in this embodiment so that the tightly wound spiral cable with removed and maximally remote from the support handset (ie in the maximum extended state) is still within the receiving box. By this embodiment of the spiral cable is achieved that the spiral cable has a total of a higher retraction force, since the retraction force of the tightly wound first portion of the spiral cable is increased by the tight turns. For the user, despite increased retraction force, only the second section of the spiral cable with the visually appealing larger windings continues to be visible.

Finally, the invention also provides for the use of spirally wound flat cables.
