Suspension and holding arrangement for a portable handheld radio communication device

Description

The invention relates to a suspension and holding arrangement for a portable handheld radio communication device, in particular for a handheld telephone, with a receiving recess and with a locking device which has a locking part protruding into the recess, and with an operating lever connected to the locking part, the operating lever being pivotable in such a way that it moves the locking part between a locking position in which it is held by a spring force and a release position, against the spring force, the receiving recess being delimited on three sides by three side walls and being open on the side on which the operating lever protrudes, and the side walls having projections which overlap at least partially at their free ends and reduce the opening width of the recess.

Such an arrangement for a portable handheld radio communication device is known from DE-GM 94 04 179. Such arrangements are used in particular in motor vehicles to provide handheld radio communication

3712E/940527/telebox

devices, such as hand-held telephones, should be positioned near the driver so that they are ready for use. On the one hand, they should leave the display and control panel clearly visible and accessible, and on the other hand, they should make it easy to remove the hand-held telephone so that the device can be picked up for a conversation.

The suspension and holding arrangement, as known from DE-GM 94 04 179, has proven itself in use. However, the prerequisite for this arrangement is that the handheld radio communication device inserted into the receiving recess is provided with a projection and/or undercuts into which the locking pin of a locking part, which can be pivoted via the operating lever, can engage. To release, the operating lever is operated so that the locking pin is released from the engagement with the handheld radio communication device, the device falls down from the recess due to gravity and can be removed for manual operation.

Another suspension and holding arrangement for a portable handheld radio communication device is known from DE-GM 93 16 700, in which two parts are provided, a vehicle-side part and a device-side part. The device-side part is hooked into the vehicle-side part by means of a tab. The vehicle-side part itself is in turn made of two parts, with a ball joint around which the holder can be pivoted within a certain range.

Based on the prior art described at the outset, the present invention is based on the object of creating a suspension and holding arrangement for a portable handheld radio communication device, in particular for a handheld telephone, whereby the handheld radio communication device that is to be held does not itself have to have any undercuts and/or projections in which a locking part locks, or has to be equipped with attachments, for example in the form of a suspension part, so that it can be held in a stationary

3712E/940527/telebox

holder can be used. Furthermore, the holder should be user-friendly.

According to the invention, the above object is achieved in a suspension and holding arrangement of the generic type in that the locking part has one or more pressure surfaces which, in the locking position, protrude beyond the bottom surface of the recess into the receiving recess, which have a coefficient of friction which is sufficient to hold a handheld radio communication device inserted into the recess by means of static friction.

It has been shown that by means of a pressure surface or several pressure surfaces on the locking part, which are pressed against the back of the handheld radio communication device, with an appropriate choice of the friction coefficients between the material from which the pressure surfaces are formed and the housing material of the handheld radio communication device, as well as the spring force with which the pressure surface^) is pressed against the underside of the housing, the device can be clamped in the holder or the recess in such a way that it is not released from the suspension and holding arrangement in the stationary position. The nature of the back of the handheld radio communication device (hereinafter referred to as "device") that is to be accommodated in the suspension and holding arrangement (hereinafter referred to as "arrangement") can be disregarded when constructing the arrangement, since sufficient clamping force or static friction between the pressure surface and the back of the device can be generated solely through the design of the pressure surfaces, i.e. through the material or the correct choice of the friction coefficient. If the device has certain unevenness on the back, the pressure surface can be covered with a suitable material that has a defined flexibility, of course taking into account the necessary friction coefficient compared to the material of the device, in order to compensate for these unevenness when placed against the underside of the

3712E/940527/telebox

Devices usually have an external dimension, i.e. in particular a thickness (distance between the front and back of the device), which varies within certain limits, since such devices are suitable for being held comfortably in one hand, so that the housing dimensions of the different devices only vary within narrow limits. Consequently, a lever arm can be formed over the length of the locking part or the position of the pivot axis in such a way that when the operating lever is operated, a sufficient displacement path towards and away from the underside of the device's housing is achieved so that the device is clamped in the recess, i.e. clamped against the projections that overlap the side walls that delimit the recess, and is thus held securely.

It has been shown that the coefficient of friction that the pressure surface of the locking part has against metal or plastic should preferably be greater than 0.5, preferably greater than 0.8. To achieve such a coefficient of friction, each of the pressure surfaces of the locking part, which is preferably made of metal or plastic, is covered with a rubber-like material, whereby such a rubber-like material usually has a coefficient of static friction against metal or plastic greater than 1.0.

In order to adapt each pressure surface to the device to be held, and to be able to easily replace the pressure surfaces if they become too worn, each pressure surface is formed by a replaceable part that is preferably inserted into a recess in the locking part. If a pressure surface is worn or if it is determined that the thickness of the pressure surface or the static friction value is no longer sufficient to hold the device inserted into the arrangement, these inserted pressure surfaces are simply removed and replaced with a new part that preferably has a self-adhesive surface.

3712E/940527/telebox

•••ft* · ·

In order to hold the device in the arrangement, the coefficient of static friction of the locking part must be set correctly, for which it is of course important to select a spring force that is sufficiently large to achieve the required pressing force. In addition, all of these forces must be absorbed on the top of the device, where the overlapping projections that limit the recess are located. To this end, it is useful to form the overlapping projections all the way around the side walls so that they are evenly positioned. It can be advantageous to also cover these circumferential projections on their surfaces that are in contact with the top of the device's housing with a material that has a high coefficient of static friction compared to the material, usually plastic, from which the device's housing is made.

Since a relatively high spring force is required to hold the device inserted into the arrangement in order to press the pressure surface(s) against the underside of the device, a corresponding force must of course be applied to release the locking element from engagement with the device by operating the operating lever. So that when removing the device from the holding arrangement, the operating lever does not have to be pressed for a long time so that the device falls downwards out of the holder, an advantageous further development of the arrangement provides a locking part which engages in the release position of the locking part or when the operating lever is operated to move the locking part into the release position and holds the locking part in its release position. In this position, the pressure surfaces are released from the device so that it can be removed downwards from the holder. Furthermore, this locking part offers the advantage that after the device has been removed from the holding arrangement, the arrangement is put into a kind of standby state in which the locking part is held in the released position and thus the cross-section is completely released in order to be able to use the device freehand.

to be pushed back into the recess from below. In this ready position, the locking part is held in its locking position by a locking spring element. In order to automatically lock the device in the arrangement again without having to operate the operating lever again, the locking part is provided with a pressure area. By exerting pressure on this pressure area, the locking part is released from its locking position engaging the locking part and releases the locking part, which is then pressed back into its locking position under the force of the spring element acting on the locking part, in which the pressure surface(s) rests on the underside of the device. Preferably, the pressure area of the locking part is shaped so that it protrudes into the recess in the locking position of the locking part, preferably in the area of the side wall that is opposite the operating lever. When the device is inserted into the recess, the front end of the device hits the pressure area of the locking part and pivots it against the force of the locking part spring element so that the locking part releases the locking part. At the same time, with such a release, the locking part spring element is pre-tensioned so that it is again in a ready state in order to press the locking part back into engagement with the locking part in its release position after the operating lever is operated to remove the device from the holding arrangement.

In order to avoid exerting forces on the locking part in the standby position of the locking part, in which the locking part spring element is tensioned, which in turn would result in an increased amount of force required to operate the operating lever to release the locking part, an advantageous further development of the arrangement provides a clamping part which engages in the locking part in the locking part release position in which it releases the locking part and holds it. In this locking part release position, the clamping part is held in place by a clamping part spring element.

3712E/940527/telebox

ment is held in its engagement with the locking part. To now lock a device in the arrangement, the clamping part is released from its engagement with the locking part so that in turn the clamping part can release the locking part in order to bring the pressure surfaces of the locking part into engagement with the underside of the device.

If both a locking part and a clamping part are used in an arrangement to achieve the above effects, the spring forces of the spring elements can be dimensioned such that the clamping part spring element has the smallest spring force that must be overcome when the device is inserted into the arrangement in order to automatically pivot the locking part and the locking part one after the other.

As described at the beginning, the thickness of devices varies within very limited ranges, so that it is usually sufficient to dimension the locking part and/or the pressure surfaces accordingly. However, these measures may not be sufficient if a larger battery is attached to the device. Devices, especially hand-held telephones, are usually equipped with a very small battery that is very flat so that it does not increase the thickness of the device too much. However, in order to equip such a device with a longer service life, these devices can be equipped with stronger batteries that are attached to the underside of the device instead of the normal battery provided by the manufacturer. This increases the thickness of the device, however, so that the dimensions between the overlapping projections on the side walls that limit the receiving recess and the pressure surfaces of the locking part may become too small. For this reason, the arrangement must be dimensioned in terms of this distance between the overlapping projections and the pressure surfaces in such a way that it is suitable for the device with the largest dimension between projections.

3712E/940527/telebox

front and back, i.e. with the thickest battery in terms of dimensions that can be attached to such a device. In order to then give the user the option of using the arrangement with a flatter battery, one or more movable parts are arranged in the bottom surface of the trough and/or in the area of the pressure surface(s) of the locking part, which optionally increase or decrease the distance between the bottom surface or the pressure surface and the overlapping projections of the side walls, depending on the pivoting position. These pivoting elements are preferably arranged in the bottom surface of the trough, on both sides of the locking part; such pivoting levers then serve to guide the device in the trough in order to prevent the device from tipping over, which would otherwise require increased pressure forces that would have to be exerted on the underside of the device via the pressure surfaces of the locking part in order to hold it securely. With regard to the aforementioned guidance of the device in the trough, pivot levers are advantageous in that they can be pivoted between two pivot positions, whereby in one pivot position they extend closer to the overlapping projections of the side walls than in the other, lower pivot position. In the upper pivot position, which can be easily set up by the user of the arrangement, a flat device, for example a device with a flat accumulator, is used, while in the other, lower pivot position the device with a larger accumulator is used. Preferably, the pivot lever in the upper position should be directed towards the free end of the operating lever in order to achieve good guidance on the underside of the device.

In motor vehicles in particular, it is common to connect the device, i.e. the handset, to the vehicle's power supply in order to supply the handset with power externally and to protect or charge the device's battery. Since it is very important not to distract the driver by handling the device,

3712E/940527/telebox

an adapter part is advantageous that can be attached to the arrangement in the area of the open side of the receiving recess and that is provided with one or more electrical contact parts. This adapter part can be changed in its position so that it is transferred into a contacting position in the locking position of the operating lever. This means that when the handset is inserted into the arrangement, the adapter part is transferred, preferably automatically under the action of an adapter part spring element, into the contacting position in which contact is made with the connection elements of the handset and thus with the power supply and possibly also with an external antenna of the vehicle. A spring element can be provided in such a way that the adapter part is released from the contacting position into a release position by moving the operating lever from the locking position to the release position, i.e. when the device is to be removed from the holding arrangement. At the same time, the adapter part spring element is tensioned again, i.e. put under pressure, in order to put the adapter part into a ready position, from which it is transferred back into its contact position when the handset is inserted into the arrangement. Such an adapter part can simultaneously serve to lock the device in the arrangement on its underside, so that in addition to the pressure surfaces, the device is secured to the holding arrangement. In order to move the adapter part from the contact position to a release position, the operating lever preferably engages in a swivel arm of the adapter part; using such a swivel arm and the appropriate positioning of spring elements, the necessary force required to release the adapter part from its contact position can be set.

Further advantages and features of the invention emerge from the following description of embodiments based on the drawing. The drawing shows:

As shown in Figures 1 to 3, the suspension and holding arrangement 1 ("arrangement 1") has a receiving trough 2 which is delimited by three side walls 3, 4, 5 which extend perpendicularly to a base surface 6. The arrangement has two fastening openings (not shown) in the base area, in which it can be installed in a stationary manner using screws or other anchoring elements in a position which is shown, such as on the dashboard of a motor vehicle. In this position, an open side 7 of the trough 2 points downwards. On the upper, free edges of the side walls 3, 4 and 5, circumferential projections 8 are formed which reduce the opening width of the trough 2 at this upper edge of the side walls 3, 4 and 5. From the open side 7, a handheld radio communication device, for example a handheld telephone 9, which is shown in Figure 2, is inserted from below into the arrangement 1 in the stationary position as shown in Figures 1 and 2, whereby the circumferential projections 8 come into contact with the housing of the handheld telephone 9 and guide it.

In the area of the base surface 6 of the arrangement 1 there is a locking part 10 which is connected in one piece to an operating lever Π, as shown in particular in Figure 5, whereby the operating lever 11, which protrudes from the free side of the receiving recess 2, is pivotably mounted about pivot pins 12 which define a pivot axis 13, as shown in Figures 3 and 4. In the top of the locking part 10 there are two recesses 14, as shown in Figure 5, into which two pressure surface elements 15 are inserted in such a way that they protrude slightly above the top of the locking part 10, as can be seen in Figures 1, 3 and 4. In addition, the two pressure surfaces 15 of these elements run at a slight incline to each other, as can again be clearly seen in Figures 7 and 8. Two locking part spring elements 16 engage on the underside of the locking part 10, which can be seen in Figures 5 and 6.

3712E/940527/telebox

while they have been omitted in Figure 4 for better clarity. These two spring elements 16 are supported on the fastening plate 17 and act to pivot the locking position or the operating lever about the pivot axis 13 in the direction of the arrow 18 in Figure 3 and thus to pivot the two pressure surface elements in the direction of the bottom surface of the trough 2.

As shown in Figure 3, in the release position of the operating lever 11 shown there, a locking part 19 with a hook area 20 at its end engages in the free end of the locking part 10. The locking part 19 is held pivotably about a pivot axis 21 at its end opposite the hook area 20 by means of pivot bearing elements not shown in detail, and in the position shown in Figure 3, in which it engages in the locking part 10, it is held by a spiral spring 22 which is supported on the rear side wall 4 of the arrangement. The locking part 19 is constructed from several surface elements that are angled to one another, with a bend, which is designated by the reference number 23, protruding into the trough through an opening 24, which can be seen in particular in Figure 1, via a rear intermediate wall, which runs approximately parallel to the side wall 4 in the upper area. If the hand-held telephone 9 is now inserted into the recess 2 from the open side 7, starting from a position shown in Figure 3, it is guided on the circumferential projections 8 until its upper end face, which carries an antenna 26 that is guided through an opening in the side wall 4, hits the bend or pressure area 23 of the locking part 19 and the locking part, pivoting about the pivot axis 21, pivots upwards against the pressure of the spring 22 and brings the hook area 20 out of engagement with the locking part 10. When the locking part 10 is released, the locking part pivots about the pivot axis 13 in the direction of the recess 2 under the action of the locking part spring elements 16, so that the

3712E/940527/telebox

a pressure surface 15, which is closer to the free end of the locking part 10, comes into contact with the underside 27 of the hand-held telephone 10, i.e. the underside of a battery 28 clamped to it, and presses the hand-held telephone against the underside of the circumferential projections 8 of the side walls 3, 4 and 5. The pressure surfaces 15 are made of a rubber material which is selected in such a way that they have a coefficient of static friction of greater than 1.0 with respect to the housing of the hand-held telephone, which is usually made of a metal or a plastic, so that the hand-held telephone 9 is held in the arrangement 1 by the static friction. It can be seen that relatively high forces, which are exerted by the springs 16, are required to hold the hand-held telephone 9 via the pressure surfaces 15; Therefore, holding the locking part 10 in the release position, as shown in Figure 3, via the locking part 19 has the advantage that, in order to insert the handset into the arrangement 1, no great force has to be applied in order to pivot the operating lever 11 or the locking part 10, but only a relatively small force, which is counteracted by the spring 22, is required in order to release the locking part 19 from its engagement with the locking part 10. In order to fix the locking part 19 in such a way that, when a hand-held telephone 9 is inserted into the arrangement 1, as shown in Figure 4, it does not exert any force on the hand-held telephone, which would cause the hand-held telephone 9 to be pushed downwards out of the recess, or conversely would require a higher force to be exerted on the pressure surfaces 15 via the spring elements 16 and the locking part 10, the free end 29 of the locking part 19 is fixed in this locking part release position of Figure 4 by a hook area 30 of a clamping part 31, which can be pivoted on a pivot axis 32, so that no force is exerted on the hand-held telephone 9 via the locking part.

To remove the hand-held telephone 9 from the arrangement 1, starting from the position shown in Figure 4, the operating

3712E/940527/telebox

lever Π is grasped with the fingers by grasping the handset 9 from the side, and the operating lever is pulled in the direction of arrow 34. The rear end of the locking part 10 approaches the clamping part 31 and abuts against the hook area 30 or an extension part, so that the clamping part 31 is pivoted about the pivot axis 32 against the force of the clamping part spring element 33 and the locking part 19 is released. The locking part 19 is in turn pivoted downwards about its pivot axis 21 in Figure 4 under the pressure of the locking part spring element 22, so that the bend 23 thereby abuts against the front face of the handset 9 through the opening 24 and presses it downwards. At the same time, the free end or the hook area 20 of the locking part 19 engages in the free end of the locking part 10, so that this in turn is held in the release position shown in Figure 3.

As the above description in conjunction with Figures 3 and 4 shows, the mechanism of the individual parts, i.e. the locking part 10, the arresting part 19 and the clamping part 31 as well as the corresponding spring elements, results in an arrangement with different lever arms, which on the one hand enable the arrangement to be released easily and on the other hand allow the pressure surfaces 15 to be pressed against the underside of the hand-held telephone 9 with a high spring force exerted via the springs 16, without high forces having to be applied when inserting the hand-held telephone 9.

In Figures 7 and 8, the arrangements 1 shown correspond to those previously described in connection with Figures 3 and 4, so that the corresponding components are not explained again. In contrast to the illustration in Figures 3 and 4, Figures 7 and 8 show a hand-held telephone 9 which has a battery 28 on its underside which is significantly flatter than the battery 28 of the hand-held telephone 1 shown in Figures 3 and 4. Devices are usually manufactured

3712E/940527/telebox

side with such a flat accumulator with a lower power and can optionally be converted to a stronger accumulator 28, which gives the hand-held telephone 9 a longer operating time. In order to enable the user of the arrangement 1 to insert a hand-held telephone 9 with both a flat accumulator and a thicker accumulator 28 without having to change the clamping mechanism, two pivot levers 35 are inserted into the base surface 6 of the receiving recess 2, namely on both sides of the locking part 10, as shown in particular in Figure 1, which are shown as individual parts in perspective in Figure 6. Each of the pivot levers 35 has bearing pins 36, about which it can be pivoted into a lower position, as shown in Figure 4, and an upper position, as shown in Figures 7 and 8. While the bearing pins 36 have no function in the lower position shown in Figure 4, and thus a relatively large distance is released between the bottom surface 6 of the recess 2 and the circumferential projections 8 in order to accommodate the hand-held telephone 9 with the thick battery 28, they are pivoted into the folded-out position (Figures 7 and 8) for holding a hand-held telephone 9 with the flat battery 28, in which they point towards the free end of the operating lever 11. In this position they provide additional guidance for the hand-held telephone 9 when it is inserted, so that it is not possible to tilt the hand-held telephone in the recess 2; precise guidance of the hand-held telephone 9 can be achieved between these pivoting levers 35 and the circumferential projections 8. In order to exert approximately the same forces on the underside of the hand-held telephone 9 via the pressure surfaces 15 in the various arrangements of Figures 3 and 4 on the one hand and Figures 7 and 8 on the other hand, the two pressure surface spring elements 15 are slightly angled towards each other, as already mentioned above, so that when the flat accumulator is used, the outer pressure surface 18 comes into contact, while when the thick accumulator 28 is used, the lower pressure surface 15 comes into contact with the bottom surface of the device 9.

In particular, during standby operation of a device, for example a hand-held telephone 9, it is desirable to connect the hand-held telephone 9 to the on-board power supply, e.g. of a motor vehicle, in order not to discharge the battery 28 of the device or to charge it at the same time. Usually, connecting cables must be plugged into the corresponding connection sockets 37 of the hand-held telephone 9 via a plug connection on the underside, so that special actions are required by the user of the hand-held telephone. Figures 9 to 11 show a supply arrangement 38 with which the arrangement 1, as described above, can be supplemented. This supply arrangement 38 has an adapter part 41, which has a carrier 39 with a holding plate 40, which can be screwed to the fastening plate 17 of the arrangement 1 via corresponding fastening parts, so that it protrudes from the underside of the arrangement 1 with the adapter part 41. The carrier 39 extends in an L-shape towards the adapter part 41, so that the top side 42 of the end region of the carrier 39 extends essentially in the plane of the bottom surface 6 of the arrangement 1. The adapter part 41 is pivotably held about a pivot axis 44 in an adapter housing 43, into which the carrier 39 merges at its end, so that it can pivot about the axis 44 between the two positions shown in Figures 9 and 10. On the side opposite the adapter part 41, in relation to the pivot axis 44, a pivot arm 45 is attached, which rests on the operating lever 11 in the position shown in Figure 9, in which the top side 46 of the adapter part 41 is aligned in the plane of the top side 42 of the carrier 39 or in the plane of the bottom surface 6 of the trough 2. The adapter part 41 is held in this position against the force of two adapter part spring elements 47 in the form of spiral springs via the operating lever Π. Two contact pins 48 are provided in the adapter part 41, which are electrically connected to a supply cable 49, which in turn is connected to the on-board power supply, e.g. of a motor vehicle. By inserting the hand-held telephone 9 into

3712E/940527/telebox

the arrangement 1 as described above with reference to Figures 3 and is, starting from the position shown in Figure 9 in which the operating lever 11 is aligned in the release position and thereby strikes against the swivel arm 45 of the adapter part 41 and holds it in the release position against the force of the spiral springs 47, the operating lever is pivoted into the locking position while releasing the swivel arm 45 of the adapter part 41, so that the adapter part 41 pivots about the swivel axis 44 due to the effect of the spiral spring 47 in such a way that the contact pins 48 engage in the corresponding connection sockets 37 on the hand-held telephone 9 and establish the electrical connection.

As shown in Figures 9 and 10, an electrical connection of the hand-held telephone 9 to the on-board power supply of a motor vehicle is made without the user of the device 9 having to take any special handling measures; the same applies to the uncoupling of the adapter part 41 from the hand-held telephone 9 when the hand-held telephone 9 is removed from the arrangement 1, for which the swivel arm 45 is provided.
