    FIELD OF THE INVENTION The present invention relates to a two-part fastener, comprising a preferably post-shaped carrier and an elongate locking element, for locking and releasing the carrier and the release of a blank and the release of a blank, respectively. , and a method of locking the locking element to the carrier to facilitate the handling of the locking element during locking and release of the blank from the fastening element, respectively. Preferably, the fastening element and the method are used when locking and releasing a body to the chassis of a radio-controlled car (RC car), but other areas of use are also conceivable, such as headlamp screens, lens hoods, covers, lids and the like where assembly and disassembly occur. an advantage if the locking element is easy to handle and keep track of when handling the parts.
    Background of the Invention It is well known to use various forms of more or less post-shaped carriers in combination with a single clip or pin and similar locking elements. A known example is described in US4822197A, which describes a two-part fastening element with a pin-like carrier with a locking element, which cooperates with the carrier for locking one part to another part. The locking element is in that case formed with an open and closed end, where the open end is passed on a pin arranged in an outlet in the end of the carrier, whereby a blank placed on the carrier is held in place by the locking element. The field of application of the fastening element according to this US document is wide and includes most things where there is a need to assemble and the possibility of disassembling different parts to / from each other. For example, in radio-controlled cars, aircraft or other radio-controlled vehicles, there is a need to keep a body in place against a chassis or chassis, but also to be able to easily detach the body from it during service, battery replacement, refueling, etc. The background and invention are exemplified below by describe the use of a so-called RC car. A body in an RC car is usually designed as a thin plastic body provided with holes which are positioned so that the body can be mounted on usually four post-shaped carriers, provided support plates or other types of abutments, on which the body rests. When the body is in place, in the most common case, a respective pin must be pushed into the designated holes in the carrier, so that locking through the pin comprises a folding on one leg of the pin, which constitutes a locking position for the pin carrier. Thereafter, the body is locked to the carrier by the pin preventing the removal of the body. A problem that occurs here is that the pin is first of all difficult to get in place when the body is well put in place because the parts are small, it is difficult to see the holes in the carrier and that the body in relation to the holes in the carrier must be in the right height to it must be possible to pass one leg of the pin through the hole in the carrier. Another problem is more of Cosmetic significance and means that the body is very easily scratched by the sprint during insertion. In addition to this, there are problems with the sprints getting lost easily or being difficult to keep track of when the body is removed from the chassis. To solve this, there are a number of solutions such as wires that hold several of the pins together, attachments to the body with wires to each pin, long pins that extend through several carriers and thus become larger and easier to keep track of, and so on. There is thus a need for a cheap, simple and easy-to-handle solution for locking and releasing a disc-shaped blank between a post-shaped carrier and a locking element, as well as a solution which takes care of the problem of lost locking elements such as pins / clips or the like.
    Disclosure of the Invention With the present invention, the object is achieved to solve the above problems from the first aspect of the invention by a two-part fastening element, comprising a - preferably post-shaped - carrier and an elongate locking element according to the preamble of claim 1, which fastening element comprises a further locking instruction. , which locks the locking element in a second locking position where the locking element substantially abuts axially with the carrier. The locking element comprises a first locking position, which means that the locking element is locked by a first locking instruction in a approximately transverse position relative to the carrier, and in which position a blank, for example a body, cover or the like, is held between the locking element and the carrier. When the blank is to be released from its held position to the fastening element, the locking element can be removed again from the carrier, but this is not the best option as it is known technology and as mentioned above has disadvantages such as handling and that it is easy to lose the locking element. Since the area of use is primarily aimed at details / blanks that are assembled - disassembled - and reassembled, the handling of the fastening element is important. Instead, it is possible with the invented fastening element to displace the locking element from the first locking position along an opening in the locking element, wherein a first hinge pin arranged on the carrier runs in the opening to a rotational position, in which the locking element cooperates with the first hinge pin, whereby it is possible to the locking element to an at least closest axial position relative to the carrier. In this axial position, the locking element is lockable in that the fastening element comprises a second locking instruction which locks the locking element relative to the carrier in a second axial locking position. Furthermore, the guide locking element is further provided in that the first hinge pin is arranged in the opening, either in rotational position or in another position along the opening, depending on whether the locking element is rotated only to that axial position or also displaced in axial joint to lock the locking element (variants are described below). Thus, the locking element does not have to be removed from the carrier, but instead it is locked to the carrier in an axially living position, whereby the cover, body, plate, lampshade or the like can be removed from a held position. As a result, the locking element is not lost either, but remains in position for future reassembly of the blank to the fastening element. When reassembling the blank to the fastening element, the locking element does not need to be fastened to the carrier again, but is only detached from the second locking instruction and rotated back to the substantially transverse position and "snapped" into the first locking instruction. "" The characteristic of the locking element is that the locking element the carrier in a releasable manner, that is to say that it is time to unlock and release from the carrier. This is because the first and the second leg of the locking element are releasably lockable to each other at the open second end, in that the respective leg / closest to the open other end has cooperating respective ramp surfaces and engaging surfaces. Thus, the open end of the locking element is closable without affecting the rest of the function where the locking element is fl superficial in relation to the carrier's first pivot between the first / locking and the rotating position, and rotatable in the rotational position and axially lockable in a second locking position. As mentioned in the preamble of claim 1, the legs of the locking element are at least somewhat graceful in relation to each other, which is required when locking and freeing the ends ti / I / apart from each other. Some previously known solutions comprise a locking element which is completely lockable to the carrier and moreover in this position is still useful for locking or releasing a substance (such as body, cover, etc.) to / from the fastening element.
    According to a preferred embodiment of the invention, the second locking instruction of the locking element comprises a second recess, which is arranged on the outside of the closed first end of the locking element. This recess is arranged to cooperate with a first cam, which is arranged at the bottom of the first recess in the carrier and in the vicinity of the abutment which is arranged on the carrier. The abutment can in this case for instance be designed as a fixed support plate, on which the blank rests in the mounted position. When the locking element in its rotational position is rotated from the transverse position to the axial position relative to the carrier, the second recess will, either directly or after displacement of the locking element in the direction of the cam, engage the cam, the locking element being locked substantially axially and alive with the carrier. In addition, when the first pivot pin is in the opening, either in the rotational position or somewhere along the opening in the locking element, the support locking element at the pivot pin is in the locked axial position. Thus, a fastening element with lockable locking element axial joint has been obtained, which has not previously existed according to known technology in the field.
    According to an alternative embodiment to the embodiment described immediately above, the recess cooperates the locking element, as described above, with a second hinge pin instead of the cam. In this case, for example, the carrier's support arms with intermediate first recesses may be longer than in the previous embodiment and instead of the position of the cam there is the second pivot. The recess on the outside of the locking element then engages in the same way with the second pivot pin instead of with the cam, either directly or after some displacement of the locking element in the direction of the second pivot pin. In the same manner as described above, the closed end of the locking element is then locked with its recess against the second pivot pin and is also supported by the device of the first pivot pin in the opening. This embodiment makes it possible to manufacture the carrier as a post-shaped carrier, with relatively long carrier arms with intermediate recesses. Between the carrier arms and at recurrently determined distances from each other, a number of guide pins are arranged, whereby the length of the carrier can be adjusted (sawn off) to suit the intended application. In the example of a fastener arranged for RC cars, the carrier can be delivered in one or two standard lengths, where the desired length is adjusted by the user, but with the advantages according to the invention, that the locking element can be moved from its first locking position, rotated around the hinge pin , and locked in an axial position that feeds the carrier. In addition, this option offers that the bracket is replaced by another locking element. As the length of the carrier is adjustable, the flexibility becomes even greater if, instead of a fixedly arranged abutment, for example in the form of a fixed support plate, a fastening element is stepped on a hinge pin in the desired position, the resting height of the blank being determined. rests on the abutment / locking element and is locked with the locking element in the manner described above. Thus, in addition to the advantages over the prior art presented above, another advantage has been achieved, namely to provide a fastening element with adjustable length and visible height on the abutment, but which retains the inventive idea of locking the locking element in an axially living position relative to the carrier.
    In another alternative embodiment of the invention, the second locking instruction is designed as an enclosure arranged at the bottom of the recess in the carrier. In this alternative, the carrier is of a certain fixed length, wherein the locking element, after displacement from the first locking instruction to the rotation instruction, is rotated and then displaced in the direction of the pit in the wearer's recess. With this the elongate locking element end engages with the pit and in this way the end is fixerted in the pit, and since the first link is always in the opening between the legs of the locking element, the locking element is supported in axial and locked position at two points - at the end and at the position of the first pivot. In a further alternative embodiment of the invention, the second locking instruction is designed as a projection arranged on one of the carrier arms of the carrier, i.e. in the recess and which projection extends a distance in the direction of the opposite carrier arm. The rotation of the locking element from the substantially transverse position to the substantially axial position relative to the carrier, the cam extends into engagement with the opening of the locking element when it comes into position for the cam extended. Because the cam protrudes is sufficiently small LL and the material present in the carrier and locking element is preferably somewhat resilient, the cam "snaps" the recess into the opening of the locking element, whereby the second, substantially axial locking position is obtained. In a preferred embodiment, the second leg of the locking element comprises a stop lug, which is arranged between the first locking instruction and the open end of the locking element. When the open end of the locking element is closed as described above, the stop lug will abut against the first leg and in this way close the locking element completely towards the open end. Thus, a closed groove is formed between the first locking instruction and the rotation instruction, and in this groove the first hinge pin runs the displacement of the locking element between the locking positions and the rotational position. The stop lug together with the reading means that the first pivot pin cannot be forced out of the first locking position and thus prevents the locking element from releasing from the carrier.
    According to a preferred embodiment, the first locking instruction is delimited by the stop lug towards the one side as above and by a first constriction in the direction of the groove which was described above. This constriction brakes the pivot sufficiently to keep the locking element in this first locking position, but the flexibility in the legs of the locking element together with the design of the constriction still allows the locking element to be displaced with some force from the first locking instruction so that the first pivot is moved against the rotation position.
    Similarly, according to a preferred embodiment, the locking element comprises a further constriction - a narrow section, which is arranged in connection with the rotation instruction. The rotation instruction is thus delimited partly by the first closed end of the locking element on one side, and by this narrow section on the other side, in direction towards the track. Thus, the first pivot pin is sufficiently maintained in the rotational position, but can with some force be obtained to leave the rotational position for moving the locking element along the groove.
    From the second aspect of the invention, the object is achieved to, with a method according to the preamble of claim 10, solve the problem that in the case of a two-part fastening element, comprising a - preferably post-shaped - carrier combined with elongated locking element, handle the locking element relative to the carrier and at the same time avoid locking element. releasing a blank to the fastener. The method comprises the steps of displacing the locking member substantially transversely relative to the carrier in the direction from a first locking position to a rotational position, and in the rotational position thereafter the rotary locking member about a first pivot from the main transverse position to a substantially axial position relative to the carrier. . Further, after the rotation of the locking element, to lock the locking element in the main axial position relative to the carrier by means of a second locking instruction, whereby a second locking position is obtained, in which the locking element substantially lives axially with the carrier. Due to this second locking position, it is easy to release the blank from the carrier because the locking element lives axially with the carrier and thus is not in the way. In addition, the locking element is already in the correct position when reassembling the blank carrier and cannot go astray while the blank is removed from the fastening element, as is the case in the prior art. After the blank has been reapplied to the wearer, it is easy to rotate the return locking element again to its transverse position and lock it in the first locking position. Such a method is known in the past.
    Through the invention, a number of advantages over known solutions have been obtained: - Easy handling when attaching or releasing a substance, for example a body, cover, screen, lens hood, etc. to a fastening element, as the locking element is always in place after the first mounting of the locking element to the carrier.
    - When the locking element is lockable in a position that lives with the carrier, there is little risk that the fastening element will come out of position when the blank is applied to the carrier.
    Quick and easy to release the locking element from the second locking position and then rotate and slide to the first locking position, whereby the blank is locked to the carrier.
    - No risk of losing the locking element.
    - No extra holders or devices are needed to keep track of the locking elements.
    According to certain embodiments, the carrier can be made flexible both in terms of the location of the abutment and the length of the carrier, which benefits the cost picture as one and the same size of carrier with same fastening elements can be used instead of several different sizes of fastening elements.
    - The fastening element can be manufactured at a low cost.

    The constructive design of the present invention will become apparent in the following detailed description of several embodiments of the invention with reference to the accompanying figures which show preferred, but not limiting, embodiments of the invention.
    Detailed description of the figures Figs. 1a-b show one part of a two-part fastening element 1 in the form of a locking element 4 in an open position. The locking element 4 comprises a first leg 11 and a second leg 12, which are connected in a closed first end 13, said opening 11, so to speak, separating the legs 11, 12 from each other. Said legs 11, 12 extend towards an open second end 14 and end with a hook-like locking device where the legs 11, 12 can be locked to each other, by cooperating respective ramp surfaces 23, 24 and engaging surfaces 25, 26. The material of the locking element 4 and the design thereof make the legs 11, 12 have some flexibility in relation to each other, both towards / from each other but also to some extent laterally, so the legs 11, 12 can be easily locked to each other by the locking device. The locking element 4 further comprises a first locking guide 16, which is delimited towards the open second end 14 by means of a stop lug 27 arranged on the second leg 12, and in the direction of the closed first end 13 it is delimited by a first constriction 29. At the closed first end 13 17, which is delimited by the closed first end 13 on one side and by a narrow section 30, on the side facing the first locking guide 16. Furthermore, the locking element 4 on the outside of the closed first end 13 comprises a second recess 19. This recess 19 constitutes in the preferred case a second locking instruction 18 in cooperation with a carrier 3, second description.
    Figs. 1c-d show the carrier 3 in a front or rear view, and a section through the carrier 3 seen from the side. The carrier 3 comprises an abutment 5 in the vicinity of a first end 6 of the carrier 3. The abutment 5 constitutes a "rest plate" for the blank 2 to be held by the two-part fastening element 1, see further description of Figures 2a-e. The first end 6 comprises a first recess 7, which extends from the first end 6 and in the direction of the abutment 5, and thus two support arms 8, 9 are formed which are separated by the first recess 7. Between the support arms 8, 9 and in the vicinity of the first end 6, a first hinge pin 10 is arranged. The guide pin 10 is arranged to cooperate with the opening 15, the first locking guide 16 and the rotation guide 17 of the locking element 4. Furthermore, a first cam 20 is arranged in close connection with the abutment 5, which cam together with the second recess 19 of the locking element constitutes the second locking guide 18, cooperates in locking the locking element 4 to the carrier 3 in a single-axis and with the carrier 3 living second locking position c, see description below.
    Fig. 2a shows the locking element 4 in its applied position on the carrier 3 after the blank 2 has been threaded onto the carrier 3, in order to be locked there by means of the locking element 4. During the application of the locking element 4 to the carrier 3 the second leg 12 is inserted into the carrier the first recess 7 and the hinge pin 10 have thus entered the opening15. The guide pin 10 is located in the first locking guide 16, which is preferably arranged approximately in the middle of the locking element 16 and adjacent to the opening 15 and the locking element 4 is arranged approximately transversely on the carrier 3 in this position.
    Fig. 2b shows the locking element 4 in its closed position on the carrier 3 after the legs 11, 12 have been locked to each other at the previously open, second end 14. Thus, the stop lug 27 has connected to the first leg 11, whereby the first pivot pin cannot be moved against the other end 14. On the other hand, it is possible to rotate the locking element 4 in the locked position to some extent until one of the ends 13, 14 goes against the blank 2. The first constriction 29 prevents the first hinge pin 10 from exiting the first locking instruction 16, and in the closed position, the opening 15 has instead formed a closed groove 28. This groove 28 runs between the first locking guide 16 and the rotation guide 17, more specifically between the constriction 29; and the narrow section 30. The locking element 4 is thus sealed in a first locking position a, in which the blank 2 is locked to the carrier 3. Now the locking element 4 never really needs to be removed from the carrier 3 but can be moved to the desired position for unloading and locking the blank 2, see further below.
    Fig. 2c shows the locking element 4 when it has been displaced so that the first guide pin 10 is in the rotation direction 17, i.e. in a rotational position b. The first guide pin 10 is thus movable along the groove 28. To move the locking element 4 from the first locking position a to rotational position b, force must be used to get past the constriction 29, and the narrow section 30.
    Fig. 2d shows the locking element 4 when it has been rotated in the rotational position b from the substantially transverse position to the position substantially axial and with the carrier 3 live. In this position it is now possible to displace the locking element 4 in the direction of the abutment 5 and the cam 20 so that the second recess 19 engages the cam 20. During this movement the first hinge pin 10 will run along the groove 28 in the axial joint seen to the carrier 3.
    Fig. 2e shows the locking element 4 when it has been displaced in axial direction, the second recess 19 engaging the cam 20. Thus the locking element 4 is locked at its closed first end 13 in a second locking position c and in addition the first pivot pin 10 cooperates with the groove 28 in support of holding the locking member 4 in this position. Now it is easy to lift the blank 2 from the rest position on the abutment 5 on the carrier 3, when the locking element 4 is secured. At the same time, it is later simple to move the blank 2 on the carrier 3 again and then lock the blank 2 in the reverse way, i.e. pull the locking element 4 in the direction from the cam 20, rotate in the rotation position b and then slide the locking element 4 to the first locking position a.
    Figs. 3a-b show an alternative embodiment of the carrier 3, which in this case means that the two carrier arms 8, 9 and the first recess 7 are more elongated than previously described embodiment, and that a number of other pivots 31 are arranged recurrently at a certain distance. Furthermore, this embodiment has no abutment 5 in that sense, but in this case it is instead possible to use a locking element 4 such as the abutment 5. The blank 2 thus rests on the locking element 4, one locking element 4 being used to lock the blank 2, exactly as previously described. It is hereby possible to determine at what height or which position the blank 2 is to be locked at and further, as shown in figure 3b, cut the support arms 8, 9 at a suitable level, the second hinge pin 31 which then becomes the uppermost, thus forming the first the guide pin 10 as previously described.
    Figs. 4a-c show an alternative embodiment of the second locking instruction 18, in that the carrier 3 comprises a pit 22 in connection with the abutment 5. The locking element 4 is designed in the same way as previously described and the first end 6 of the carrier is otherwise very similar to the previous embodiment, with the two carrier arms 8, 9 and the intermediate first hinge pin 10. By rotating in the rotational position b, in the same way as before, the locking element 4 so that it ends up in the position which feeds axially with the carrier 3, and then displaces the same in the direction of the abutment 5, the closed first end 13 gradually engages the corresponding pit 22. Thus, the first end 13 is locked in the second locking position c and in the same way as before the first hinge pin 10 functions as a support in the groove 28, in that it is in a position between the first locking guide 16 and the rotating guide 17.
    Figs. 4d-f show an alternative embodiment of the second locking guide 18, in that the carrier 3 comprises a projection 32, which which is arranged at the first end 6 and further arranged to cooperate with the groove 28 for establishing the second locking position c. that the locking element 4 is rotated in the rotational position from the substantially transverse position to the position substantially axial and with the carrier 3 living, the projection 32 engages with the groove 28, whereby the second locking position c is provided. The distance between the support arms 8, 9, the thickness of the locking element 4, the height of the projection 32, and some flexibility make the locking element 4, so to speak, snap and a guide and a support for the axial position with the support 3 are also provided by the first pivot 10 in the rotation instruction. 17. 1 = fastening element 2 = blank 3 = carrier 4 = locking element 5 = abutment 6 = first end (carrier) 7 = first recess (carrier) 8 = carrier arm 9 = carrier arm 10 = first pivot 11 = first leg 12 = second leg 13 = first end (locking element) 14 = second end (locking element) 15 = opening 16 = first locking instruction 17 = rotation instruction 18 = second locking instruction 19 = second recess (locking element) 20 = fëßsta cam 21 = bottom 22 = pit 23 = ramp surface 24 = ramp surface 25 = engagement surface 26 = engagement surface 27 = stop lug 28 = groove 29 = first constriction 30 = narrow section31 = second articulation pin 32 = extension a = first locking position = rotation position c = second locking position BOMB
