Description

  • The invention relates to a locking element according to claim 1, a connection arrangement for connecting a first component to a second component according to claim 9 and 11, an arrangement of a first component and a second component according to claim 14 and a method for assembling such an arrangement according to claim 15 ,
  • Such locking elements or connection arrangements can be used in various fields of technology, for. B. to quickly connect two components together and also provide a fast detachable connection. An advantageous field of application of the invention is the connection of loudspeaker boxes to one another, in particular in the region of hanging arrangements of loudspeaker boxes for large events. Such an arrangement of mutually suspended speakers is also referred to as a line array. Since such line arrays are permanently transported from one event to the next event, where they are set up and dismantled each time, which is not easy due to the size and weight of the line arrays, there is a great need to improve the set-up and design To make the mining process as simple, fast and safe as possible. A corresponding proposal comes from the DE 10 2008 017 507 B4 out.
  • From the EP 1 698 531 A1 is a steering wheel lock on a motor vehicle known.
  • From the US Pat. No. 6,213,672 B1 is a cleaning device with a latchable, variable-length telescopic handle known.
  • The invention has for its object to provide a locking element and a connection arrangement with which the connection of two components and the release of each other can be made even easier, faster and safer. Furthermore, an advantageous arrangement of a first component and a second component and an advantageous method for mounting such an arrangement should be specified.
  • This object is achieved by a locking element according to claim 1.
  • The invention has the advantage that the bolt can first be brought into an axial position in which it is already biased and is also locked. The bolt then does not need to be held by hand. Also, for the release of the lock no separate manual action is required, except for the manual operation to be performed anyway for the connection process. Rather, the locking element can be made so to speak "sharp" by the bolt is introduced into its locked axial position. Thereafter, without requiring a separate separate manual actuation of the bolt or other actuator, the connection between the first and the second component can be made, since the lock can be solved solely by a mechanical loading of the projecting from the housing part of the bolt so that the bolt can extend and engage in a corresponding mounting hole on a connecting element. The locking element according to the invention or a connection arrangement formed therewith thereby allows easy handling and ergonomic operation when connecting the components. Also, the release of the components from each other is carried out in a simple and pleasant way.
  • The spring-loaded bolt can be designed in particular as a snap-in bolt or as a self-tightening bolt, which, if it is not locked, automatically extends in the direction of the extended axial position. The lock can be designed in the form of a locking detent, which can be overcome by an increased biasing force, or by a positive locking, which can be solved by a certain movement.
  • According to an advantageous embodiment of the invention, the mechanical loading of the protruding from the housing part of the bolt comprises one or more of the following types of admission:
    • a) axial movement of the bolt in the direction of the retracted axial position,
    • b) axial movement of the bolt in the direction of the extended axial position,
    • c) rotational movement of the bolt about its longitudinal axis.
  • In case a), the bolt is thus pressed against the force of the spring a little further to release the lock. Accordingly, the locked axial position is to be chosen such that there is still some room for axial movement of the bolt in the direction of the retracted axial position. In the case b), a reverse axial movement occurs as compared with the case a). In this case, some residual clearance should be provided between the locked axial position and the extended axial position. Said axial movement of the bolt can be effected by a mechanical loading of the part of the bolt protruding from the housing in such a way that a connecting element with which the bolt is to be connected is moved against the part of the bolt projecting out of the housing. The movement of the connecting element may already be a component in the axial direction of the bolt to cause the axial movement of the bolt. The axial movement of the bolt can also be caused by a radial movement of the connecting element, ie a movement perpendicular to the axial direction of the bolt. In this case, the connecting element may have a bevel, which converts a radial movement of the connecting element in the manner of a ramp corresponding to an axial movement of the bolt. Advantageously, combinations of an axial movement and a radial movement of the connecting element can be realized.
  • In case c), the rotational movement of the bolt z. B. caused by moving a connecting element against the protruding from the housing part of the bolt, wherein the rotational movement z. B. by friction between the connecting element and the bolt, a toothing between the connecting element and the bolt or acting on a cam existing on the pin can take place.
  • The mechanical loading of the protruding from the housing part of the bolt may also comprise a combination of the types of loading a), b) and c), z. B. a combination of axial movement and rotational movement of the bolt.
  • All mentioned types of admission have the advantage that a simple and reliable release of the lock can be done without additional operating means must be operated.
  • According to an advantageous embodiment of the invention, the bolt can be locked by the locking means in an axial position which lies between the retracted and the extended axial position. Depending on requirements and application, the locking element may also be formed with a plurality of axial positions in which the bolt can be locked. As a result, the locking element is particularly flexible.
  • The bolt can be formed lockable by the locking means in principle with respect to any component located in the environment, in particular with respect to components that are not part of the locking element.
  • According to an advantageous embodiment of the invention, the bolt can be locked by the locking means relative to the housing of the locking element. This has the advantage that the locking element can be provided as a separate, self-sufficient unit, which already has all the necessary features for locking the bolt and releasing the lock.
  • According to an advantageous embodiment of the invention, the bolt is spring-loaded relative to the housing of the locking element by the spring or at least one separate additional spring in the direction of rotation about the longitudinal axis of the bolt. This has the advantage that the type of application "rotational movement of the bolt about its longitudinal axis" can be realized in a particularly simple and with little effort, since the required rotational movement of the bolt about its longitudinal axis by the spring in a simple manner can be generated.
  • According to an advantageous development of the invention, the locking element has a cam guide device acting between the bolt and the housing with at least one cam and at least one guide contour, wherein the cam guide device is adapted to a rotational movement of the bolt about the housing during an axial movement of the bolt relative to the housing To produce longitudinal axis. The cam guide device is a further advantageous possibility to realize a release of the locking of the bolt by a mechanical loading of the protruding from the housing part of the bolt. By the cam guide means an axial movement is automatically converted into a rotational movement at the same time, so that ultimately a release of the lock by a combination of axial movement of the bolt and rotational movement of the bolt generated therefrom about its longitudinal axis. The cam may optionally be arranged on the bolt or the housing. The guide contour is then arranged on the respective other component (bolt or housing). The guide contour can z. B. be a slope with a uniform slope or progressive or degressive slope.
  • According to an advantageous embodiment of the invention, the locking element has at least one manual actuating element, with which the bolt is manually adjustable at least in the locked axial position. By the manual actuator, the bolt can also be set in other positions and in particular a rotational movement of the bolt about its longitudinal axis can be generated. As a result, can be realized for the user quickly learnable or intuitive operation of the locking element, eg. B. an axial movement of the bolt and a rotational movement to bring the bolt in its locked axial position.
  • According to an advantageous development of the invention, the manual actuating element is at the same time designed as a cam of a cam guiding device. This favors a simple structure the locking element with only a few components.
  • The above-mentioned object is also achieved according to claim 9 by a connection arrangement for connecting a first component to a second component, wherein a locking element formed with a spring-loaded bolt is fixed to a holder of the first component and the second component, a connecting element is attached, wherein the Connecting element in a region which is adapted for connection to the first component, at least one fastening hole, which is designed for engagement of the bolt, wherein the locking element is designed as a locking element of the type described above. This allows a quick connection of the components together and a release of the components from each other in a simple and pleasant way.
  • According to an advantageous development of the invention, the connecting element has a groove extending in the longitudinal direction of the connecting element, within which the at least one fastening hole is arranged, wherein the groove extends at least in one direction along the connecting element beyond the fastening hole. This has the advantage that the protruding from the housing part of the bolt of the locking element can first be placed during the process of connecting the first component with the second component in the groove. Then, the connecting element relative to the bolt can only be moved in the direction of the groove. When the bolt reaches the mounting hole, it can automatically snap into it. This allows a simple, intuitive guidance of the attachment hole of the connecting element to the bolt. In particular, when the connecting element is movably attached to the second component, for. B. is pivotally mounted on the second component, the groove is a helpful guide means for guiding the mounting hole to the bolt. In particular, an initially z. B. two-dimensional mobility of the connecting element relative to the bolt can be reduced by the groove in a substantially only one-dimensional mobility.
  • The object mentioned at the outset is also achieved according to claim 11 by a connection arrangement for connecting a first component to a second component, wherein a locking element formed with a spring-loaded bolt is fastened to a holder of the first component and a connecting element is fastened to the second component, wherein the Connecting element in a region which is adapted for connection to the first component, having at least one fastening hole which is formed for locking the bolt, wherein the connecting element has a groove extending in the longitudinal direction of the connecting element, within which the at least one fastening hole is arranged the groove extends beyond the attachment hole in at least one direction along the connection member, the groove being disposed on an outer side of the connection member. It can thus be the advantages explained above with any other locking element, eg. B. a commercial snap-in bolt, realize.
  • According to an advantageous embodiment of the invention, the width of the groove substantially corresponds to the diameter of the mounting hole. This promotes a secure guidance of the bolt in the groove towards the mounting hole.
  • The attachment hole may be formed as a blind hole or as a through hole. If the attachment hole is formed as a blind hole, the depth of the groove may be less than the depth of the attachment hole.
  • Of course, the connecting element may also have more than one mounting hole. The mentioned features of the mounting hole can then apply to several mounting holes.
  • According to an advantageous development of the invention, the connecting element is chamfered on at least one longitudinal edge or on two longitudinal edges arranged on the same side of the connecting element. As a result of the chamfering, when the connecting element is moved relative to the bolt, in particular by a radial movement of the connecting element relative to the longitudinal axis of the bolt, the bolt can be slightly pushed back by applying mechanical force to the part of the bolt protruding from the housing, i. H. be moved in the direction of the retracted axial position. In conjunction with a locking element according to claim 1, the locking of the bolt can be solved by this mechanical loading at the same time.
  • The above object is also achieved according to claim 14 by an arrangement of a first and a second component, which are at least one articulated joint or connected to each other, wherein the arrangement comprises at least one connection arrangement of the type described above, which is spaced from the joint is.
  • The above-mentioned object is also achieved according to claim 15 by a method for assembling an arrangement of the type described above, comprising the steps:
    • a) manually moving the bolt of the locking element of the connecting arrangement into its locked axial position,
    • b) moving the connecting element to the part of the bolt protruding from the housing until the bolt engages in the groove of the connecting element,
    • c) moving the connecting element relative to the bolt within the groove until the bolt engages in at least one fastening hole of the connecting element.
  • These steps do not all have to be done immediately and directly one after the other. In particular, when assembling and suspending the so-called line arrays, a sequence is made possible by the invention so that the pre-assembled to the step b) speakers are provided and then raised by a crane. When pulling up the speakers, the movement is automatically carried out according to step c), so that only when pulling up the final engagement of the bolt takes place in the mounting hole.
  • The invention will be explained in more detail by means of embodiments using drawings.
  • Show it:
  • 1 : a locking element in sectional view and
  • 2 a locking element in the assembled state and
  • 3 : a connection arrangement and
  • 4 to 7 : articulated loudspeaker boxes in different states of assembly and
  • 8th to 10 : Embodiments of guide grooves.
  • In the figures, like reference numerals are used for corresponding elements.
  • The 1 shows a locking element 1 in sectional view, ie a housing 2 of the locking element 1 is shown cut so that the internal components are recognizable. The locking element 1 points in the housing 2 a bolt 3 on, the axial, ie in the longitudinal direction L of the bolt 3 in which case 2 is movable. A part 10 of the bolt 3 protrudes from the case 2 out. In the case 2 is also a spring 7 arranged through which the bolt 3 opposite the housing 2 more precisely against a rear wall of the housing 2 , is sprung. The feather 7 is in the embodiment according to 1 designed as a compression spring. Also embodiments of the locking element with a tension spring can be advantageously realized.
  • The advantage is the bolt 3 thus formed as a spring-loaded self-tightening bolt, by the force of the spring 7 out of the case 2 is extended when the bolt 3 not hindered by external influences.
  • The bolt 3 is in the case 2 in a range between a retracted axial position 6 and an extended axial position 4 axially reciprocable. Between the retracted axial position 6 and the extended axial position 4 is an intermediate position 5 present, in which the bolt on locking means, which are described in more detail below, can be locked. This intermediate position 5 is also referred to as a locked axial position. In addition to the axial mobility of the bolt may also have a rotational mobility.
  • The housing 2 can at its front area an external thread 9 have, over which the locking element 1 can be easily attached to another component, ie it can be screwed there. At the bolt 3 is also a manual actuator 8th attached, the z. B., as in the 1 recognizable as by a transverse bore of the bolt 3 plugged rod can be formed. The rod can z. B. via a press fit on the bolt 3 be fixed. The housing 2 has corresponding recesses in the form of longitudinal slots, in which the rod 8th is guided.
  • The 2 shows the locking element 1 as previously based on the 1 described, with further details. The locking element 1 is over the external thread 9 in a carrier plate 11 screwed in and over a lock nut 12 fixed on it. The carrier plate 11 is with a frame-like bracket 13 whose function will be discussed in more detail later. Already it should be noted that the frame-like bracket 13 two substantially parallel holding elements 13a . 13b between which a channel 16 is formed. Each of the retaining elements 13a . 13b has a hole 15 on, through which the bolt 3 with its outstanding part 10 can snap through. The holes 15 Therefore, they have substantially the same diameter as the diameter of the bolt 3 at least in the protruding from the housing part 10 or are slightly larger.
  • In the 2 is also the manual actuator 8th and its leadership in a slot-like recess 19 of the housing 2 shown in more detail. The manual actuator 8th , which is formed as explained in the form of a rod, forms together with the slot-like recess 19 , a protruding housing nose 17 and a leadership contour 18 both a locking means and a cam guide means. As can be seen, runs the slot-like recess 19 starting from the left initially approximately in the longitudinal direction of the housing 2 and then turn to the right end of the case 2 down to the left, causing the protruding housing nose 17 of the housing 2 is formed, behind which the manual actuator 8th can be hooked. Due to the compressive force of the spring 7 is the manual actuator 8th securely locked in this position. On the protruding housing nose 17 opposite side of the slot-like recess 19 is the guide contour 18 ,
  • You can tell that the bolt 3 with its outstanding part 10 in the channel 16 between the holding elements 13a . 13b protrudes, but this does not fully penetrate. As can also be seen, the guide contour runs 18 obliquely to the longitudinal direction of the housing 2 or to the axial direction of movement of the bolt 3 , In this state, the projecting from the housing part 10 of the bolt 3 mechanically in the axial direction against the pressure force of the spring 7 acted upon, acts the manual actuator 8th as a cam, on the guide contour 18 along slides. Due to the oblique arrangement of the guide contour 18 becomes the manual actuator 8th then in the direction of the axially extending portion of the slot-like recess 19 guided, so that by means of the protruding housing nose 17 and the actuator 8th caused locking is overcome. Is then the mechanical loading of the protruding from the housing part 10 of the bolt 3 canceled, this can due to the pressure force of the spring 7 snap out, ie he can then in the direction of the extended axial position 4 move.
  • The 2 also shows that the manual actuator 8th For ergonomic reasons at the ends can be provided with protective caps made of soft or elastic material. The manual actuator 8th can be designed in particular as a metal rod.
  • The 3 shows a connection arrangement for connecting a first component with a second component in an isometric view. Is recognizable in the 3 again the previously explained holder 13 with the between the holding elements 13a . 13b formed with substantially constant width channel 16 as well as via the carrier plate 11 and the locknut 12 on the bracket 13 fastened locking element 1 , The locking element 1 is at one end of the holder 13 attached, in the representation of 3 at the far end. At the opposite end of the bracket 13 or in an end region with a certain longitudinal extent, the holder 13 a variety of mounting holes 36 on. In one of the mounting holes 36 is a retaining bolt 35 used, with the one in the channel 16 arranged connecting element 31 is held. The connecting element 31 is over the retaining bolt 35 swiveling in the channel 16 attached. The variety of mounting holes 36 makes it possible for the respective mounting situation, a suitable positioning of the connecting element 31 on the bracket 13 to select, ie the connecting element 31 can be moved further forward and further back or further up or down on the bracket as needed 13 by means of the retaining bolt 35 be attached.
  • Like in the 3 In addition, it can be seen, the connecting element has 31 an elongated shape. The connecting element 31 is set up with a locking element 1 an adjacent bracket 13 in the 3 lower left (ie in the foreground) is shown to be connected. For this purpose, the connecting element 31 a connecting portion extending through a longitudinal direction of the connecting element 31 running groove 32 and one in the area of the groove 32 arranged mounting hole 33 is formed. The mounting hole 33 is in the 3 by way of example at the rear end of the groove 32 arranged, but can also in principle at any other point of the groove 32 be provided. The groove 32 penetrates the material of the connecting element 31 not completely, but only partially, as will be shown later on the basis of sectional drawings. The mounting hole 33 may be formed as a blind hole, in which case it has a greater depth than the groove 32 , The mounting hole 33 can also be formed as a through hole.
  • The connecting element 31 also indicates a to the bolt 3 of the locking element 1 facing side along the longitudinal edges extending bevels 34 on. The bevels may have a linear, ie ramped, or a non-linear course, z. B. progressive or degressive. The bevels 34 may be formed in particular as chamfers. The connecting element 31 acts on at least one of the bevels 34 as well as the groove 32 and the mounting hole 33 with the bolt 3 of the locking element 1 the adjacent bracket 13 together, as follows from the 4 to 7 is explained in more detail.
  • The 4 to 7 each show in the left area two articulated connected components in the form of speakers 40 . 41 in a side view, or in a partially sectioned illustration. The 4 to 7 also show a cut area AA of the speaker 41 and their connection arrangement (top right) and a detail view B from the sectional view AA (bottom right).
  • For all 4 to 7 applies that a first speaker box 41 with a second speaker 40 about a joint 42 is hingedly connected, such that the backs of the speakers to which connection arrangements with the already described brackets 13 are fixed, can be moved relative to each other until a desired position is found in which a final positional fixation is to take place. The speakers 40 . 41 have more fasteners 43 on, the additional speakers can be coupled to it articulated.
  • The at the back of each speaker 40 . 41 arranged connection arrangement with the holder 13 is there in a depression 44 arranged sunk, so this in the side view of the speakers 40 . 41 only in the cut area of the speaker 41 is recognizable. The sectional view AA shows how the bracket 13 with a locking element 1 in the depression 44 arranged and at the back of the speaker 40 . 41 is attached. The detailed view B reproduces the part relevant for the description of the function of the connection arrangement in an enlarged manner.
  • According to 4 it is initially assumed that the locking element 1 in the pretensioned position "sharp" is set by the bolt 3 in the locked axial position 5 is brought, with the bolt 3 over the actuator 8th and the protruding housing nose 17 is locked.
  • The 5 shows a subsequent phase of connecting the backs of the speakers 40 . 41 , The connecting element 31 is according to 5 now in the channel 16 the holder 13 introduced and hits with a lower chamfer 34 on the out of the case 2 of the locking element 1 outstanding part 10 of the bolt 3 , The bevel 34 is so on the outstanding part 10 of the bolt 3 matched that the locking element 31 further into the canal 16 can be introduced and thereby by means of the bevel 34 the bolt 3 pushes back in the direction of the retracted axial position, but this does not necessarily have to be achieved. In any case, by pushing back the bolt 3 the locking solved because, as previously based on the 2 described the manual actuator 8th in its function as a cam on the guide contour 18 along slides and the protruding housing nose 17 overcomes. This condition is in the 6 shown. As can be seen, then lies the bolt 3 with the out of the case 2 outstanding part 10 in the groove 32 , The groove 32 Hereinafter acts as a guide for guiding the bolt 3 to the mounting hole 33 ,
  • The 7 shows how the bolt 3 to the mounting hole 33 to be led. While in the 4 to 6 the speakers 40 . 41 are not moved relative to each other is in the 7 recognizable that a relative movement between the speakers 40 . 41 was carried out, via the joint 42 , In the course of this movement the bolt moves 3 with the outstanding part 10 in the guide groove 32 along and finally reaches the mounting hole 33 , The bolt 3 snaps due to the force of the spring 7 and then penetrates both the mounting hole 33 as well as the hole 15 in the holding element 13a the holder 13 , As a result, a solid lock in the rear area of the speaker 40 . 41 produced.
  • The fastening of the loudspeaker boxes 40 . 41 over the locking element 1 and the connecting element 31 can be picked up again, in which the bolt 3 by means of the manual actuator 8th is retracted in the direction of the retracted axial position.
  • The 8th to 10 show exemplary advantageous embodiments of the locking means and cam guide devices, again in the form of reference to the 2 explained slot-like recess 19 where the slot-like recess 19 each formed differently and thus the cam is guided differently. While in the previous embodiments, the manual actuator 8th at the same time has formed the cam, may also be provided that the cam is formed separately from the manual actuator. The basis of the 8th to 10 illustrated embodiments apply to both variants, wherein uniformly the cam in each case by the reference numeral 80 and the slot-like recess with the reference numeral 81 is designated. The cam 80 is in the 8th to 10 each shown several times, it being understood that in a practical realization in a respective groove 81 only once exists. For a better illustration, the cam 80 but here in each case in the extended axial position 4 , the locked axial position 5 and the retracted axial position 6 played.
  • The 8th shows an embodiment of a slot-like recess 81 similar to the one based on 2 explained slot-like recess 19 is trained. The cam 80 can turn over a protruding housing nose 82 be guided and locked behind it in the locked position. It is again a guide contour 83 formed over which the cam 80 when pushing back the bolt 3 can drive while the cam 80 in the axially extending portion of the slot-like recess 81 returns. As can also be seen, the axially extending portion of the slot-like recess 81 even further beyond the range of the guide contour 83 extended to the rear, ie to a range 84 so that there is a retracted, retracted axial position 6 results.
  • The 9 shows that the locking element according to the invention in principle without the protruding housing nose 17 . 82 can be realized with the described locking function, z. B. over a substantially perpendicular to the axial direction of the bolt 3 extending section 86 the slot-like recess 81 , The lock can in this case z. B. by appropriate friction between the cam 80 and the section 86 the slot-like recess 81 be formed, or by a corresponding roughness of these components. It is beneficial to the section 86 slightly wider than the diameter of the cam 80 , so that with a mechanical loading of the protruding part 10 of the bolt 3 the cam 80 loose in the section 86 can be guided and by the force of a torsion spring in the axially extending region 81 . 84 the slot-like recess 81 can be returned.
