    Attachment device for removably attaching object to mobile unit {A DEVICE FOR RELEASEABLE ATTACHMENTS OF OBJECTS TO A MOBILE UNIT}
    Apparatuses for simply and securely attaching mobile objects, for example attachment devices for attaching child seats to cars, bicycles, baby strollers and the like, are needed in many different fields. A common method for attaching a child seat to a vehicle is to use a special strap attached to the seat or footstool or other straps that hold onto the vehicle seat. One problem with these devices is that they vary in a large degree of safety and there is a risk of overturning the child seat in the event of an accident due to the inability to obtain a rigid fixation attachment. Another problem is that fixed points vary from vehicle to vehicle, compromising the solution with the child seat manufacturer.
    Standardized solutions have been proposed for rigid fasteners with four fastening points and for secure attachment. To date, this standardized solution requires corresponding mating devices in child seats with four attachment points. In this regard, there is a risk that it is difficult to achieve a secure connection in one and the same state at all four points. Another standardized solution is proposed, which uses two fixed points and in some cases requires additional points of the support in the form of adjustable vertical members, for example.
    For example, in GB-A 288 328, a dismountable attachment device is already known, but in order to achieve a locked position, not only linear but also rotational movements are required. In addition, the previously known mechanisms require a relatively large structure height, for example to place the child seat at a very high position.
    The present invention relates to an attachment device for removably attaching an object to a mobile unit.
    The invention is described with reference to the following examples and the accompanying drawings.

    10 and 11 schematically show the adjusting mechanism forming part of the first coupling member.
    It is an object of the present invention to achieve a sufficiently secure attachment using an attachment device that is easy to use and highly reliable.
    The object is achieved by a dismountable attachment device, wherein the engagement members of the device provide a corresponding guide surface and a support surface to center the two engagement members around an engagement symmetry axis, the guide surface and the support surface being On the one hand to form an outer surface on one of the engaging members to form a dome shape, on the other hand the guide surface and the support surface to form the inner surface on the other engaging member so as to form a cup or opposite shape, It is structured to hold the locking member in the disengaged position while the member is in the first engaging position and to keep the locking member in the locked position while in the final engaging position, the two engaging members are connected to each other and the inner surface is closely connected. Contact and center around the outer surface.
    The attachment device according to the invention consists of two foundation members, the main components of which are clearly shown in figures 1 to 4 of the other figures. The first foundation member shown in FIGS. 1 and 2 consists of a first engagement member 1, which is fixed to a vehicle seat, for example in a mobile unit. The second foundation member shown in FIGS. 3 and 4 is shown as a second engagement member 2, which is installed on the underside of the object, which is structured to be releasably attached and to be held by the mobile unit. . The first engagement member 1 provides a guide surface and a support surface 3, 4, which in such a way as to allow the second engagement member to be supported and attached to the first engagement member in a rigid and reliable manner. 2) cooperate with the corresponding surface within. In the example shown, the first engagement member is designed as a raised or domed region which is essentially conical with the envelope surface forming the guide surface as well as the support or holding surface for the second engagement member 2. In order to install the attachment device at a reasonable height overall, the cone angle is relatively small, but the cone angle can be varied in a large range depending on the installation case in question. At the circumferential guide edge 5 leading to the periphery of the engaging member and circular in the example shown, the conical guide surface and the support surface 3 are transformed into the guide surface and the support surface 4 in the form of a cylinder jacket in the example shown. . Optionally, the guide and support surface 4 may be in the form of a conical jacket which can enhance the guide effect.
    In order to lock the coupling members 1 and 2 with each other, the structure is arranged to cooperate with the locking member 11-14 in the second coupling member 2 which is installed in the first coupling member 1 and will be described in detail later. A locking device 6 composed of a plurality of locking members 7-10 is provided. To adjust the locking member, adjustments are made to the coupling members 1 and 2 so that the coupling members can be connected to each other and can be adjusted between a separate position where they are separated from each other and a locking position that can be locked to each other in a relative position where the coupling member is fixed. Instruments 15 and 16 are provided. The adjustment mechanism will be described in more detail later.
    5 and 6 illustrate a preferred embodiment in which a motor vehicle, for example a system for attaching a child seat, for example in a vehicle seat 17 of a passenger car 18, is adapted. In this connection, the joining member 1 is installed on a flame 19 having four fastening points 20, 21, 22, 23, for example in the form of a self-locking member in the form of a ring, which member is intended for a vehicle. It is attached to the corresponding fixed point in the seat. This solution, which constitutes a fastener with four fastening points, has been proposed as a solution for several passenger car models, but in this case, an adapter that allows a frame with four fastening points to be permanently installed in the vehicle seat. It is used as an alternative to form a device that allows two engaging members 1 and 2 to releasably attach a child seat to a vehicle seat. Flame 19 may be designed in several different ways. For example, a fold link 24 may be provided which is folded into a flame member 25 that projects downward in the storage position. The engagement member 1 may be attached to the flame in a number of different ways, but for example may be attached by means of a support plate 26 extending between the support members and supporting the engagement member 1. It can also be attached by means of a cross bar. By means of the switch lever 26 ', the engagement member 1 can be adjusted to another inclined position with respect to the flame shown by way of example. In this way, for example, the inclination of the child seat may be individually adjusted to the other inclination of the seat.
    7, 8 and 9 illustrate a more detailed example of the configuration of the locking device 6 and the adjustment mechanisms 15 and 16, the structure being adjusted between the disengaged position and the locked position.
    The locking member 7-10 described above of the locking device 6 in the first coupling member 1 constituting the lower coupling member in this example is obliquely downwardly projecting essentially radially through the opening 24. The pin is oriented through the cylindrical wall, which also forms the support surface 4 of the engagement member 1 in its unaffected initial position and in the locked position to be described in detail later. In the illustrated example, the number of locking pins is four and divided equally around the circumference of the engagement member, but the number and arrangement can be divided into large ranges. The locking pins 6, 9 constitute the outer ends of the locking bars 6 ′, 9 ′ extending through the holes 6 ″, 9 ″ in the stay tube 27, which are in the interior of the locking member 1. It protrudes downward from the side. The guide surface and the support surfaces 3, 4 comprising the guide edge 5 of the locking member 1 are centered around the axis of symmetry 32 of the locking member 1.
    7, 8 and 9, the second engagement member 2 has an internal shape which is adjusted in the form of a dome which is turned upwards of the exterior of the first engagement member, the internal shape being an engagement member ( It has an inner cup-shaped space 28 which is configured to engage with the outer shape of 1). Accordingly, the engagement member 2 has a corresponding guide surface and support surfaces 29, 30, which extend concentrically around the axis of symmetry 32 of the engagement member 2. In the example shown, one of the guiding surface and the supporting surfaces 29 is constituted by a similarly conical shell surface, but this is essentially the supporting surface on which the engagement member 2 extends annularly, or at an appropriate position and at an appropriate height. With the support head positioned, by this means, the support member 2 obtains a rigid support for the lower engagement member and the members are connected to each other. However, it is preferable that the support surface 30 is preferably the same as the support surface 4 of the lower engagement member because it provides a dimensional deviation that provides a suitable tolerance.
    The lower part of the support surface 30 and the wall 31 is end-shaped by an edge 31 ′, which runs around the engagement member and in the example shown is a bottom engagement which is circular and will be described in detail later in detail. A guide edge is formed on the member 1 to cooperate with the guide surface 4 and the guide edge 5. The wall 31 is provided with locking members 11-14 in the form of through holes, the number and position of which are suitably adjusted by the number and position of the locking pins 6-9. However, it is also possible for larger numbers of holes to be provided if a locking position in several different torsional positions of the upper locking member 2 with respect to the lower locking member 1 is required. As clearly shown in FIGS. 3 and 7, the support surface 30 has a groove 12 ′ running between the holes 12, 13, 14 around the coupling member, which groove is described in detail later. It is structured to receive the locking pins 6 and 9 at positions between the holes to be described.
    The above-mentioned adjustment members 15, 16 are in such a way as to cooperate with the locking member 6 in such a way that it is possible to readjust the adjustment member between the separation position and the engagement position. In the example shown, the adjusting member 15 of the lower coupling member 1 is constituted by a press which is essentially cylindrical in the center, and the zone can be moved at least linearly in the longitudinal direction of the axis of symmetry 32. The pressing portion 15 has a pressure plate 33 which is configured to cooperate with the cord members 34 and 35, which protrude slightly downwardly from the inside of the upper coupling member 2. To release the locking device, a centrally positioned adjustment member 36 is provided, which may be raised or lowered by means of the control knob 37, which handle 37 is clearly shown in FIG. 4. It is installed in such a way that it is easily accessible from the outside of the upper coupling member 2 and is rotatably aligned in the upper coupling member around the link 38.
    According to the invention, the adjustment member 15 on the lower engagement member in such a way that an adjustment movement of the locking member 6-9 of the lower engagement member occurs between the initial position according to FIG. 7 and the pressed position according to FIG. ) Is installed. This adjustment can be achieved in several different ways and is solved by means of inclined slits 15 'in the wall region within the adjustment member, as in the example shown in FIGS. 7-9. The transverse pin 15 ″ protrudes into the slit 15 ', which is firmly attached to the inner ends of the lock bars 6', 9 '. In this way, the movement of the pressing part 15 is deformed in the direction of the axis 32 by the radial adjustment movement of the locking members 6, 9.
    10 and 11 schematically illustrate another example of a mechanism for transmitting motion between the adjustment member 15 and the locking member 6-9. In this example, the lock bar 25 is not entirely radially oriented, but it cannot be turned but can be turned around the symmetry axis and the push button 39 which can be moved axially along the symmetry axis 32. It consists of a rotary disk 40. This rotational movement is achieved by means of the helical cam 39 'on the push button, which extends along the recess 40' in the rotating disk 40. As shown in FIG. In this connection, the cord members 34 and 35 of the upper engagement member cause the push button to be pressed, which causes the rotational disk to be rotated by its axial movement and also the length of the locking bar fixed in the rotational disk. A displacement movement in the direction is generated to produce an adjusting movement of the lock bar 6-9.
    Departing from the above mentioned basic mechanism and cord members 34 and 35 of the locking member and the adjusting member, the illustrated engagement member is provided with additional cord members 41 ', 42' (see FIG. 1). In the example shown, these additional cord members are installed as arcuate grooves 41 in the lower engagement member, which is structured to cooperate with the pilot 42, which pilot 42 is introduced into the interior of the upper engagement member. Protrude downward from the groove. This arc-shaped groove has a limited angular extension, for example 180 °. This allows a relative pivoting movement between the two engagement members over a limited angular spacing, such that, for example, the child's seat turns crosswise in the longitudinal direction as the child seat rotates, for example at 90 ° to the engagement position. Makes it possible to be located.
    7, 8, and 9, for example, the attachment device used to attach a child seat to a car seat and to release the child seat is described in a comprehensive manner. In this connection, Fig. 7 schematically shows the outline of the lower section of the child seat 41, on which the upper coupling member 2 is installed. When the child seat and the upper engaging member 2 are completely separated from the lower engaging member 1, the adjusting member 15 of the lower engaging member is positioned in an initial position, for example an unpressed initial position. This position is held by a spring, for example a pressure spring, a pressure spring means, which makes it possible to hold the locking member 6 in an outwardly protruding position, for example in a locked position, and also in the upper unpressed position. Maintain 15.
    8 shows the two engaging members 1, 2 in a connected position, with the child seat being adjusted from the side such that the upper engaging member 2 is centered on the lower engaging member. On the one hand, it cooperates between the guide edge 5 and the guide surfaces 3, 4 in the upper engagement member, and on the other hand, between the edge 31 ′ and the guide surfaces 29, 30 in the upper engagement member. By cooperation, the two engaging members are forced to a rigid support position centered around the central axis 32. In this way, the downwardly protruding cord members 34 and 35 of the upper engagement member apply pressure to the adjustment member by applying pressure against the pressure area 42 of the adjustment member 15, By means of the locking pins 6-9 are held in the withdrawn position. In this regard, the locking member 6-9 has an advantage but is not entirely recessed in the lower coupling member 1 and possibly not located perpendicularly to the front of the hole 11-14, but the coupling member It protrudes into a guide groove 12 'leading to the periphery. This provides a temporary locking position in which the upper engagement member 2 is allowed to rotate without the risk of overturning the device. The child seat 41 then rotates approximately one quarter per revolution while the locking member 10 continues in the guide groove 12 'and when a rotational movement occurs such that the recess is positioned perpendicular to the front of the pin. Eccentrically positioned adjusting pins 34, 35 protrude downward in corresponding recesses 43, 44. In this way, the pressing action on the pressure area 33 is stopped and the adjusting member 15 springs out toward its initial position (eg FIG. 9). Due to the fact that the slit 15 'cooperates with the locking member 6, in this connection is located perpendicular to the front of the corresponding opening 11-14 of the upper engagement member, the locking pin is in the locked position, which is This is due to the fact that the locking pin is inserted into the corresponding opening. In this way all locking pins are simultaneously moved to the extent of movement along this movement. The fact that a complete locking position is secured is indicated by the fact that the outer ends of the locking pins 6-9 are indicated by a clearly visible contour mark and the ends protrude to a range such that they are easily observed by the user. Has an advantage. In order to avoid the end of the locking member being hooked on any edge area, the end is preferably slightly rounded. Accordingly, if the lock pin is jammed or otherwise disturbed, the lock pin will not be adjusted to the locked position.
    When the two engagement members are connected to each other, the attachment device is completely loaded and moved and the device exerts a very high pressing force in the locked position, which greatly increases safety in the event of an accident.
    In order to disengage the attachment device, the control knob 37 is pressed against the adjustment member 16 and the kinetic adjustment pin 36 exerts a force to press the adjustment member 15 by the raised area in the illustrated example. Add. In this way, the locking members 6-9 are recessed from the locked position to the separated position, and the child seat can be raised and removed. The above-described groove 12 'is circular in shape between the holes 11-14, and the upper engagement member 2 is rotated while guiding the locking tabs during separation, which facilitates seating through the door opening by this means. Eliminates the risk of the child's vehicle tipping over during a quarter of a turn to lift it up. In this way, the separation is carried out in two stages which can be adjusted by means of the control knob 37 and can be provided in two defined positions, for example by means of the holding mechanism.
    The attachment device described above can be applied to several other examples. For example, an object other than a child seat may be attached to a safety box, for example a luggage boot, an animal cage, for example. The attachment device may also be used to attach a stroller attachment to a mobile unit other than a car, for example a child seat or stroller flame. By means of the attachment device, the child seat may also be attached to a bicycle or the like. In addition, the attachment device may have a structure different from that described above. Illustratively an illustrative symmetrical embodiment is shown, but it is possible to replace the conical surface in a planar shape, for example a polygonal pyramid.
    Conversely, the cup-shaped coupling member 2 can be installed in the flame, but the dome-shaped coupling member 1 can be turned downward and installed in the dismountable member.
