A sliding transmission element (4, 4') coupled to the drive (2) is arranged on the basic carrier and has a first translatory position and a second translatory position, such that the transmission element (4, 4') is designed in the second translatory position for fixing a locking element (3, 3'). On the basic carrier (10), furthermore, one of the locking elements (3, 3') is arranged, which is designed in a first adjustment position for preventing the movement of the transmission element (4, 4') from its first translatory position and in a second adjustment position for locking the basic carrier (10), while a first abutment (5, 5') is present which is designed for stopping the movement of the basic carrier by hitting against a second, fixed abutment (6, 6'). A fixed guide (7, 7') is furthermore present, which keeps the locking element (3, 3') in its first adjustment position over a path of travel (a).

Description

DRIVING AND LOCKING MECHANISM FOR AN EXTENDIBLE FRAME
The invention relates to a motion and locking mechanism for extendible device parts and to a corresponding method of moving and locking extendible device parts.
Space-saving embodiments of multifunctional devices or devices with device components that are not always required (for example larger displays in navigation devices in cars, or keyboards for a simple writing of, for example, SMS messages by means of a mobile telephone used in a car) are of major importance, especially in view of the rising number of different functions that can be operated with such an infotainment device. Such extendible device parts have at least one position in the retracted state and one position in the extended state, in which the device part must be securely locked so as to relieve the drive from mechanical loads and maintain the device part in this position against the influences of vibrations or user actions (such as typing on a keyboard or knocking against a display).
The number of components and the cost for such a motion and locking mechanism should be kept low.
It is accordingly an object of the invention to define a motion and locking mechanism such that it can be assembled in as few as possible mounting steps, that it can be manufactured at low expenditure, and that it locks the device part to be extended in a robust and reliable manner in the various positions.
This object is achieved by means of a motion and locking mechanism as described in claim 1. It is advantageous if the basic carrier, on which the extendible device part is mounted, is stable, i.e. is made, for example, of metal. The more complicated, often moving parts which transmit the locking and motion may be realized as injection-molded synthetic resin parts. This saves expensive processing steps of metal parts. It is necessary here for the basic carrier material to have no adhesive joint to the injection-molded synthetic resin, i.e. that the basic carrier material is, for example a metal, in particular steel.
It is particularly advantageous if the parts arranged on the basic carrier are manufactured in a single injection-molding step or several consecutive injection-molding steps, and are connected to the basic carrier. For this purpose, the basic carrier is made to form part of the injection-molding tool during the injection-molding step. This saves the mounting of individual elements on the basic carrier, can be realized in a time-saving and inexpensive manner, and leads to smaller tolerance problems because the parts all originate from the same tool. Several injection-molding steps are useful if, for example, different synthetic resins are used. A further advantageous embodiment of the motion and locking mechanism according to the invention is obtained when means for detecting the position of the transmission element are provided, which means render possible a control of the drive. The drive can then be automatically switched off when the fully extended or the fully retracted position has been reached. If the fixed elements are arranged on a fixed frame, there is a further advantageous possibility to provide also the fixed frame with the fixed elements (for example guides and/or abutments) by means of a synthetic resin injection-molding process, which saves expense also here and reduces the number of parts to be assembled.
Claim 6 relates to a method of moving and locking extendible device parts. The motion and locking mechanism according to the invention is particularly suitable for fully recessed or partly recessed device parts such as, for example, the display of a navigation system or the keyboard of an infotainment device.
The invention will be explained in more detail below with reference to an embodiment and a drawing, in which: Fig. 1 shows the motion and locking mechanism with its fixed frame,
Fig. 2 shows the motion and locking mechanism in its retracted position without its fixed frame but with fixed guides,
Fig. 3 shows the motion and locking mechanism in an intermediate position without the fixed frame but with fixed guides, and Fig. 4 shows the motion and locking mechanism in its extended and locked position without the fixed frame, but with fixed guides.
Fig. 1 shows the motion and locking mechanism in its retracted (fully recessed or partly recessed) position, with also the fixed frame 1 being shown. The fixed frame 1 serves to fasten the motion and locking mechanism and the unit supported by the motion and locking mechanism, for example a display 25, for example in the dashboard of a car. It is also visible in Fig. 1 that the fixed guides 7, 7' (cf. Figs. 2 to 4) in this embodiment are secured to the fixed frame 1 by means of fastening elements 7a, 7b, 7a', 7b' which are passed through respective openings in the frame 1. These fastening elements 7a, 7b, 7a', 7b1 have been made simultaneously with the actual guide 7, 7' in one synthetic resin injection-molding step and have thus become part of the guide 7, 7'. Similarly, the second fixed abutments 6, 6' are fastened to the fixed frame 1 by means of retention elements 6a, 6a'. Furthermore, the drive 2 in this embodiment is mounted to the fixed frame 1. A basic carrier 10 is guided in fixed guide rails 9, 9'. Several movable elements are arranged on the basic carrier, among them the locking elements 3, 3' and the movable motion transducers 4, 4', which in this embodiment are implemented as movable toothed racks with lateral grooves for guidance in a slot 4.1, so that a portion of the basic carrier 10 enters these grooves and renders possible a sliding movement in the longitudinal direction of the slot 4.1.
Fig. 2 shows the motion and locking mechanism without the fixed frame 1 in the non-extended position. The guides 7, 7' and the second fixed abutments 6, 6' are again shown for making clear the motion principle. These elements are to be regarded as fastened to the fixed frame 1. The drive 2 has a pinion 2a which is connected to a second pinion 2a' via a coupling shaft 2b. The pinions 2a, 2a' transmit the drive motion (rotational) to the toothed racks 4, 4', which can slide on the basic carrier 10, such that the shifting of the toothed racks from their first translatory position is prevented by the locking elements 3, 3'. The toothed racks 4, 4' convert the rotational movement of the pinions into a linear movement of the basic carrier 10. The fixed guides 7, 7' keep the locking elements 3, 3' in the first adjustment position in which the locking elements 3, 3' prevent a shifting of the movable toothed racks 4, 4' (the toothed racks 4, 4' are locked), h the embodiment shown, the locking elements 3, 3' comprise locking arms 3a, 3b, 3a', 3b' which act on the locking of the toothed racks as long as the locking elements 3, 3' are kept in the first adjustment position, and which cause the locking of the basic carrier 10 in the second adjustment position. To move from the first adjustment position to the second adjustment position, the locking elements 3, 3' are supported with rotation possibility about respective points of rotation 3c, 3c'. Furthermore, first abutments 5, 5' are provided on the basic carrier 10, which are designed for stopping the movement of the basic carrier 10 by abutting against the second, fixed abutments 6, 6'.
Fig. 3 shows the motion and locking mechanism in an intermediate position of movement. The basic carrier 10 has been moved outwards relatively to the fixed frame 1 through a transmission of motion from the pinions 2a, 2a' to the toothed racks 4, 4' in the guide rails 9, 9'. The guides 7, 7' keep the locking elements 3, 3* still in the first adjustment position, so that the movable toothed racks 4, 4' are kept in the first translatory position. The rear wall of the basic carrier 10 is not shown here. On this wall, for example, a display 25 is arranged, hi addition, portions of the toothed racks 4, 4' and of the locking elements 3, 3' project beyond the rear wall of the basic carrier 10 such that these structures cannot detach themselves from a basic carrier. Examples of this that may be mentioned here are the fastening elements 7a, 7a', 7b, 7b' and the retention elements 6a, 6a', which also belong to the guides 7, 7' and to the second, fixed abutments 6, 6' and which ensure that these elements cannot detach themselves from the frame and are fixedly connected thereto.
It is described in EP 0 530 919 Bl how movable injection-molded parts of synthetic resin can be manufactured on a metal carrier structure without the movability being limited or prevented by the shrinkage of the synthetic resin after the injection-molding process. This technique is the so-called movable outsert parts technology (MOP technology). The synthetic resin materials used may be thermoplastic or duroplastic. The movable synthetic resin parts that can be manufactured in such an injection-molding process are, for example, the toothed racks 4, 4' and the locking elements 3, 3'.
Fig. 4 shows the motion and locking mechanism in the fully extended position in which the locking of the basic carrier 10 by the locking elements 3, 3' is already operational. To reach this position, the locking elements 3, 3' first leave the first adjustment position imposed by the guides 7, 7' after traveling a path length a along the guides 7, 7' and reach a stage of intermediate free adjustability. The first abutments 5, 5' hit against the second, fixed abutments 6, 6' and stop the movement of the basic carrier 10. Since the drive continues to operate, the movable toothed racks 4, 4' are freed from their fixation in the first translatory position by the guided locking elements 3, 3' and shifted to the second translatory position. The free portion of the slot 4.1 shows the achievable path of movement, however, this is typically not fully utilized. In the embodiment shown here, the toothed rack is not moved fully up to the ends of the slots. When the toothed racks 4, 4' are set in motion, the forces acting on the locking arms 3a, 3a' ensure that the locking elements 3, 3' are rotated into the second adjustment position, in the direction of the guides 7, 7' (direction Rl). i this embodiment, the locking arms 3b, 3b' then abut against the fixed guides 7, 7'. Rounded shapes of the guides 7, 7' and the locking arms 3a, 3a', 3b, 3b' as shown in Figs. 2 to 4 render possible a smooth transition to a stationary position of the basic carrier 10 in that the toothed racks 4, 4' right from the start of their release from the first translatory position follow the locking arms 3a, 3a' which swivel away, while the locking arms 3b, 3b1 approach the guides 7, 7'. The toothed racks 4, 4' start moving relatively to the basic carrier 10 in the slots 4.1 during this. As a result, the movement of the basic carrier 10 is slowed down so smoothly before the first abutments 5, 5' make contact with the second, fixed abutments 6, 6', in spite of the fact that the speed of the toothed racks 4, 4' may remain the same, that the movement of the basic carrier 10 is not abruptly stopped. When the toothed racks 4, 4' reach the second translatory position, the locking elements 3, 3' are fixed in their second adjustment position thereby at the same time. The basic carrier 10 and the display 25 fastened thereto are thus locked to the fixed guides 7, 7', and the drive is relieved from carrying the weight of this unit. The drive is stopped when the toothed racks 4 reach the second translatory position. This is achieved, for example, in that a sensor lever operates a first switch (not shown). A photosensitive barrier may alternatively be used as a sensor instead of the switch.
The return travel of the basic carrier will now be described. The drive 2 is switched on again and now operates in the opposite direction. The movable toothed racks 4, 4' are moved from their second translatory position into the first translatory position again, because the base plate 10 is still locked to the fixed guides 7, 7' and cannot be moved. While the movable toothed racks 4, 4' are being moved into the first translatory position, the locking elements 3, 3' are relieved from their fixation in the second adjustment position. The forces acting on the locking arms 3b, 3b' rotate the locking elements 3, 3' about the points of rotation 3c, 3c' in the direction of the toothed racks 4, 4' (direction R2), i.e. into the first adjustment position. The basic carrier 10 then again loads the drive and can be moved inwards. The fixed guides 7, 7' again ensure that the locking elements 3, 3' are kept in the first adjustment position. In this position, the locking elements 3, 3' lock the movable toothed racks 4, 4' in their first translatory position. After traveling a path length a, the sensor lever 8 in cooperation with a second switch (not shown) causes the drive to be stopped. The basic carrier 10 and the display 25 have been returned to their original position again.
The embodiment of the motion and locking mechanism described above shows how a mutual locking and fixation is achieved by means of several movable elements on the basic carrier 10 in cooperation with fixed elements. Various embodiments of this invention are conceivable, for example for obtaining an enlarged travel path length and thus a full disappearance of the basic carrier, or a transmission of movement from the drive 2 to transmission elements which do not lead to a purely linear motion. An automatic pivoting could then form part of the motion and locking mechanism.

A motion and locking mechanism as claimed in claim 1, characterized in that the basic carrier (10) is made from a material which forms no adhesive connection to the synthetic resin during the injection-molding of synthetic resin parts, and in that the parts arranged on the basic carrier (10) are synthetic resin injection-molded parts.
3. A motion and locking mechanism as claimed in claim 2, characterized in that the movable synthetic resin injection-molded parts are provided on the basic carrier (10) in one synthetic resin injection-molding step or in several synthetic resin injection-molding steps, in particular by the MOP technology.
4. A motion and locking mechanism as claimed in any one of the claims 1 to 3, characterized in that means (8) are present for detecting the position of the transmission elements (4, 4'), and a control of the drive (2) is exerted in dependence on the detected position.
5. A motion and locking mechanism as claimed in any one of the claims 1 to 4, characterized in that the fixed guide (7, 7') and the second, fixed abutment (6, 6') are arranged on a fixed frame (1).
6. A method of moving and locking extendible device parts, comprising the steps of
• starting a drive (2) which is coupled to a movable transmission element (4, 4') that has a first translatory position and a second translatory position, which element is arranged on a movable basic carrier (10), • moving the basic carrier (10) by means of the transmission element (4, 4'), during which a locking element (3, 3') arranged on the basic carrier (10) is held in a first adjustment position by a fixed guide (7, 7') and this first adjustment position prevents the movement of the transmission element (4, 4') from its first translatory position,
• releasing the locking element (3, 3') from the first adjustment position through reaching of an end of the guide (7, 7') after traveling a path (a),
• stopping the motion in that a first abutment (5, 5') arranged on the basic carrier comes into contact with a second, fixed abutment (6, 6'),
• moving the transmission element (4, 4') into the second translatory position, and
• fixing the locking element (3, 3') in its second adjustment position in that the transmission element (4, 4') reaches its second translatory position, whereby this second adjustment position locks the basic carrier (10).
7. A navigation system with a motion and locking mechanism as claimed in any one of the claims 1 to 5.
