Description

The invention relates to a mount and in particular a wall mount for a musical instrument, in particular a stringed instrument, with an adjustable base for receiving an instrument body and with at least two retaining arms which can be pivoted relative to an anchor element for detachably fixing an instrument neck received between the retaining arms, the base and the two Retaining arms are coupled to one another via at least one connecting link, and at least one spring is provided which biases the base into a rest position and the two retaining arms into an open position.

Such mounts are usually designed as wall mounts or floor stands. If a wall bracket is used, the anchor element is regularly attached to a wall. In the case of a floor stand, a stand that can be set up on a floor is typically used as the anchor element. In principle, the anchor element can also be connected to such a frame. In any case, the anchor element functions as a whole as a fixed point for the two retaining arms that can be swiveled in relation to it. The base can also be adjusted with respect to the anchor element, specifically between a rest position in the unloaded state and a working position in the loaded state.

When the base is in the rest position, the two holding arms are in their open position. This allows the musical instrument to be held to be placed on the base. Due to the weight of the musical instrument, the base moves from its resting position to its working position. At the same time, the two holding arms are moved from their open position or open position to a closed position Position or closed position pivoted. All this happens against the force of the spring.

A bracket and in particular wall bracket of the structure described above is in the CN 205564263 U treated. In fact, the body of the instrument is placed on supports here. As a result, the two articulated arms carrying the supports move apart against the force of a spring. Two holding arms at the head are closed and ensure that an instrument neck is detachably fixed. The two articulated arms are connected to the holding arms via cables and in particular Bowden cable cables.

In addition, a guide is provided which encloses the aforementioned spring. The ends of the two articulated arms are adjustable within the guide. The other end of the two articulated arms is coupled to each other. As a result, an overall relatively complex mechanical structure is observed, which tends or can tend to malfunction due to the use of the guide for the articulated arms on the one hand and the Bowden cables between the articulated arms and the holding arms on the other hand. A guide used at this point can, for example, get dirty, so that the possibility of adjustment and thus the functionality is impaired.

A comparable holder for a musical instrument is in the US 8,490,942 B1 described. In this case, too, pivotable holding arms are provided for the detachable fixing of an instrument neck. The two holding arms can be pivoted in relation to an anchor element which is connected to a foot or floor stand or forms part of such a floor stand. The basis for recording the When the instrument body is put down, the instrument body performs a pivoting movement.

The pivoting movement of the base is transmitted to an angle lever via an adjusting rod. The pivoting movement of the angle lever caused by the adjusting rod ensures, against the force of a spring, that the two holding arms for fixing the instrument neck can be opened and closed. In this case, too, a complex mechanism is pursued, which is prone to malfunction when it is dirty and tends or can tend to functional impairments. Because the movement of the base is deflected several times, which can lead to malfunctions in the case of impairments such as dust in the joints. This is where the invention aims to remedy the situation overall.

The invention is based on the technical problem of further developing such a holder and in particular a wall holder for musical instruments in such a way that the functionality is improved, taking into account a simplified mechanical structure.

To solve this technical problem, a generic mount and in particular a wall mount for a musical instrument is characterized in that the connecting link between the base and the two holding arms is designed as a connecting rod rigidly coupling the base to the two holding arms, the connecting rod being connected with the aid of the longitudinal extension of the Connecting rod following spring is preloaded.

As a rule, the connecting rod is firmly attached to the base or firmly connected to the base. In contrast, the connecting rod and the two holding arms are usually advantageous via a common one articulated joint. For this purpose, the joint is regularly provided on the head side of the connecting rod. In addition, the procedure is generally such that the base and the two holding arms define a common setting plane in the course of their respective setting movement. The connecting rod is also moved within this setting level. In this way, a particularly compact and mechanically simple construction can be realized, which, in contrast to the prior art, does without complicated rail guides, deflection levers, etc.

Rather, the invention typically uses only a single joint, namely the common joint, with the aid of which the connecting rod or the rigid connecting member and the two holding arms are coupled to one another. In addition, since the two holding arms and the base carry out their respective adjustment movement in the common adjustment plane, complicated deflections of the adjustment movement are unnecessary. This not only simplifies the mechanical structure, but also increases the functionality in particular, because Bowden cables, angle levers, adjusting rods, etc., as in the prior art according to the US 8,490,942 B1 or also according to the CN 205564263 U can be omitted. This is where the main advantages can be seen.

According to an advantageous embodiment, the holding arms and/or the base are designed to be adjustable at least transversely to the longitudinal extension of the connecting rod. This means that different instrument sizes can be easily accommodated. As a rule, at least the connecting rod is designed to be telescopic. This applies in particular in the event that guitars or generally stringed instruments of different sizes are to be detachably fixed with the aid of the holder according to the invention.

In general, the two holding arms are pivotably connected to the anchor element via at least one joint. The anchor element is in turn coupled to a floor frame or designed as a component part of such a floor frame. Then the holder according to the invention is designed as a floor stand for holding musical instruments. As a rule, however, the anchor element is fixed to a wall. In this case, the mount according to the invention is designed as a wall mount for the musical instrument in question.

A structurally and functionally simple design is observed for the case in which the two holding arms are designed as holding plates that can be moved in the positioning plane. In fact, the two holding plates can, for example, be moved back and forth transversely to the longitudinal extent of the connecting rod. In this case, the holding plates are advantageously scissor arms. In addition, it is possible for the holding plates in the positioning plane to be pivoted on an arc of a circle in relation to the elongate connecting rod. In any case, the holding plates have at least one protruding holding finger, with the help of which the instrument neck of the musical instrument to be held is typically detachably fixed.

In order to be able to rule out any damage to the instrument neck from the outset at this point, the respective holding finger rests essentially perpendicularly on the holding plate and, if necessary, is curved inwards. In addition, the holding finger has at least one soft, elastic surface. This can be realized in that a plastic has been applied to the holding finger or a hose made of plastic is pulled over the holding finger.

In any case, the movement of the two holding arms or the movable holding plates or also the scissor arms in the positioning plane during the transition from the open position of the holding arms to their closed position and vice versa results in the instrument neck of the musical instrument to be picked up being fixed in the closed position and in the open position is released for withdrawal. The holding arms are controlled gravimetrically by placing the instrument with its instrument body on the base. As a result, the base goes from its rest position to the working position.

The associated adjustment movement of the base in the adjustment plane causes the rigid connecting rod connected to the base to act on the holding arms via its head-side joint, in that the holding arms move from the open position assumed in the rest position of the base to the closed position as soon as the base is in its working position due to the weight of the musical instrument placed on it.

The invention recommends that the base be equipped with at least two support fingers so that the instrument body can be held properly on the base. The support fingers regularly extend at an angle to the positioning plane in order to provide a sufficiently large contact surface for the instrument body. As in the case of the holding fingers as components of the holding arms, the two carrying fingers also advantageously have a soft, elastic surface in order to prevent damage to the surface of the instrument body. As described above, the procedure can be such that the two carrying fingers are each equipped with the soft elastic plastic coating on their surface or a corresponding plastic hose is simply pulled over the relevant carrying finger and fixed. In any case, the The soft, elastic surface of the two carrying fingers also ensures that damage is not only avoided when the musical instrument is placed on the base, but that this process is also carried out practically noiselessly.

The spring, which preloads the base in its rest position and the two holding arms in the open position and which is generally compressed when the base moves into the working position and the two holding arms into the closed position, follows the longitudinal extension of the connecting rod according to the invention. That is, the spring is placed parallel to the rigid connecting rod. As a result, the spring is usually also arranged in the common actuating plane. As a result of this, the holder according to the invention is particularly narrow because practically all functional elements move in the positioning plane or are arranged in the positioning plane. The only exceptions to this are the holding fingers on the holding arms and also the carrying fingers of the base. As a result, the installation space required for the holder according to the invention is small and it can, for example, be accommodated and shipped in a compact packaging.

The spring is typically a helical coil spring, although other springs may be used at this point. In principle, recourse to several springs is also conceivable. In addition, it is recommended that the spring surrounds the connecting rod and/or is connected to it in its longitudinal extension or follows the longitudinal extension. In both cases, this design supports the compact design. If the spring is connected to the connecting rod in its longitudinal extent, this is advantageously done on the head side. That is, the spring is coupled to the head of the connecting rod.

In addition, it has proven useful if the spring is connected to the connecting rod on the one hand and to the anchor element on the other hand or is supported against the anchor element. In this way, movements of the connecting rod lead directly to the fact that the spring on the one hand prestresses the base in the rest position and the two retaining arms in the open position and on the other hand is compressed when the base moves into the working position and consequently the two retaining arms into the closed position.

The reverse can also be done. In this case, the spring is as it were compressed in the rest position of the base and is stretched when the base moves into the work position and, consequently, the two support arms move into the closed position. In both cases, the spring ensures the desired pretensioning of the base in the rest position and of the two holder arms in the open position.

The entire holder according to the invention is regularly made from metal profiles or metal plates in order to enable a particularly stable and durable design. In this context, practically all conceivable metals such as copper, brass, steel, stainless steel, etc. can be used with or without a coating. Of course, for optical reasons, it is also possible to paint the metals or coat them with plastic, for example. In principle, however, the individual parts of the holder according to the invention can also be made of plastic, wood or other materials. Mixed forms are also conceivable.

As a result, a mount, and in particular a wall mount, for a musical instrument is made available that is characterized by a strikingly simple mechanical structure and few functional elements are convincing, so that low manufacturing costs, minimized weight and high functionality can be expected. As a result, the holder is not only predestined for extensive and long-term use, but is also designed to be particularly advantageous with regard to shipping. In this context, a particularly small construction volume plays a special role, which is essentially limited to the positioning level as described.

In the figures, a holder for a musical instrument 1 is shown, which in the embodiment and not restrictively as a wall bracket for fixing is set up and provided on a wall 2. In principle, the holder could also be designed as part of a floor stand. In this case, an anchor element 3 is not attached to the wall 2, but rather to a floor frame, or is designed as part of this floor frame.

In its basic structure, the holder according to the invention has, in addition to the previously mentioned anchor element 3 , an adjustable base 4 which is designed and set up to accommodate an instrument body 1a of the musical instrument 1 . In fact, the musical instrument 1 is, within the scope of the exemplary embodiment and not restrictively, a guitar and in particular an electric guitar. In addition to the instrument body 1a, this also has an instrument neck 1b, which is also detachably fixed with the aid of the holder.

For this purpose, at least two holding arms 5 are provided which can be pivoted relative to the anchor element 3 and which serve to detachably fix the instrument neck 1b of the musical instrument 1 held between the holding arms 5 . The base 4 and the two holding arms 5 are coupled to one another via at least one connecting link 6 . A spring 7 is also provided.

The design is chosen so that the spring 7, the base 4 in a 4 dot-dash rest position biases. The two support arms 5 are using the spring 7 in one in the 4 also biased open position shown in phantom.

In the rest position of the base 4 and corresponding to the open position of the two support arms 5 according to the dash-dotted representation in FIG 4 or the one in the 2 Following the illustrated open state, the musical instrument 1 can be placed on the base 4. For this purpose, the instrument body 1a is placed on at least two support fingers 8 of the base 4, which in the embodiment according to Fig.1 to 5 are connected at the ends to the connecting member 6 as components of a U-shaped fastening bracket. As soon as the musical instrument 1 is placed with its instrument body 1a on the support fingers 8 or the base 4, the weight of the musical instrument 1 ensures that the spring 7 is compressed. You can see that in the transition from 2 to the 4 .

With the compression of the spring 7 is in the embodiment after the Figures 1 to 4 accompanied by an actuating movement T of the base 4, which in the 4 is represented by a double arrow and is manifested during the transition of the base 4 from the rest position shown in dot-dash lines to the working position shown in solid lines. As a result of this actuating movement T of the base 4, the two holding arms 5 are also pivoted, starting from their open position in FIG 2 or according to the dash-dotted representation in the 4 in her in the 4 solid closed position shown. This is accompanied by a further adjustment movement S of the support arms 5, which in the embodiment according to the Figures 1 to 4 to one in the 4 indicated arch movement S corresponds or to a transverse movement compared to the longitudinal extent of the connecting member 6, as shown in FIGS 2 and 5 is reproduced. As a result, the instrument neck 1b of the musical instrument 1 in the in 4 solidly illustrated closed position of the holding arms 5 fixed, until the musical instrument 1 is lifted with its instrument body 1a from the base 4 again. Because then the support arms 5 go from their in the figure 4 Solid drawn closed position in the open position shown there in phantom lines, which also in the 2 is reproduced.

According to the invention, the connecting member 6 is designed as a connecting rod 6 that rigidly couples the base 4 to the two holding arms 5 and is pretensioned with the aid of the spring 7 . In fact, the connecting rod 6 is designed to be telescopic, so that different sizes of the musical instrument 1 to be accommodated can be accommodated. For the telescoping ensures in the embodiment Figures 1 to 4 indicated fixing screw or generally a fixing means 9, with the help of which an extension rod can be more or less immersed in a dip tube than both components of the connecting rod 6 and can be fixed in the appropriate position.

According to the exemplary embodiment, the base 4 and the two holding arms 5 perform the adjusting movement T of the base 4 in the longitudinal extension of the connecting rod 6 on the one hand and the curved pivoting movement S or also a transverse movement S in comparison to the connecting rod 6 for the holding arms 5 on the other. Both adjustment movements S, T define a common adjustment plane E, in which the connecting rod 6 is also moved. The anchor element 3, the spring 7, the two holding arms 5 and also the base 4 are consequently and essentially arranged in this common positioning plane E, which leads to a particularly compact and slim construction of the holder according to the invention. The only exceptions to this are the projecting support fingers 8 of the base 4 on the one hand and the retaining fingers 10 also projecting in relation to the retaining arms 5 on the other hand. In fact, the support fingers 8 and the holding fingers 10 are predominantly oriented in such a way that they protrude, for the most part, perpendicularly with respect to the base 4 or the holding arms 5 and thus the setting plane E, namely downwards the exemplary embodiment from the plane of the drawing in the direction of the viewer.

In order to avoid damage to the instrument body 1a and the instrument neck 1b, both the carrying fingers 8 and the two holding fingers 10 are each equipped with a soft-elastic surface, as has already been described in detail in the introduction. The base 4 is rigidly connected to the connecting rod 6 on the underside. On the head side, the connecting rod 6 is coupled to the two holding arms 5 via a joint joint 11 . According to the exemplary embodiment, the joint 11 is formed in such a way that a joint pin connected to the connecting rod 6 engages in respective guides on the holding arms 5 . As soon as the connecting rod 6 is moved downwards in the transition of the base 4 from its rest position to the working position according to the exemplary embodiment, as is the case in FIG 2 indicated by the arrow, the pivot pin follows the downward movement and ensures that, according to the exemplary embodiment, the two holding arms 5 carry out the arcuate pivoting movement already described, on the one hand in the 4 indicated clockwise and on the other hand counterclockwise. As a result, the two holding fingers 10 connected to the holding arms 5 move towards one another and can accommodate the instrument neck 1b between them. The pivoting movement of the two holding arms 5 is stopped as soon as the holding fingers 10 rest on the outside of the instrument neck 1b.

In addition to the joint 11 on the connecting rod 6 provided on the head side, the two holding arms 5 are each pivotably connected to the anchor element 3 via at least one further joint 12 . In this further joint 12 is a rotary joint, which the described pivoting movement of the relevant support arm 5 clockwise or im Counterclockwise allows, as seen when transitioning from to the 4 shown in phantom open position of the support arms 5 to the closed position of the support arms 5 detects in the 4 is shown solid. The two holding arms 5 are holding plates that can be moved in the setting plane E in the context of the exemplary embodiment according to FIG Figures 1 to 4 . In the variant after the figure 5 the two holding arms 5 are each designed as scissor arms, which in turn are connected to the connecting stage 6 via the head-side joint 11 on the one hand and, on the other hand, are connected to the anchor element 3 via a joint 12 in this case. The two scissor arms in this case have an additional central scissor joint 13. In the area of this scissor joint 13, the two holding fingers 10 are attached to the holding arms 5 or the scissor arms in the example figure 5 connected.

As already explained, the holding fingers 10 are essentially perpendicular to the associated holding arm 5 . In addition, the retaining fingers 10 are advantageously curved inwards in order to be able to fix the instrument neck 1b properly. The spring 7 follows the longitudinal extent of the connecting rod 6. The spring 7 is a helical coil spring in the context of both exemplary embodiments. In principle, of course, a different type of spring can also be used as an alternative.

As part of the variant after the Figures 1 to 4 the spring 7 is designed as a helical coil spring surrounding the connecting rod 6 . In contrast, the spring 7 in the variant after the figure 5 connected in the longitudinal extension of the connecting rod 6 to this, namely at the head end. In both cases, the spring 7 is connected at one end to the connecting rod 6 and at the other end to the anchor element 3 or is supported against the anchor element 3 . As a result due to its preload, the spring 7 ensures that the base 4 is moved to its rest position and the two holding arms 5 are moved to their open position as long as no musical instrument 1 is being picked up.

However, if the musical instrument 1 is placed with its instrument body 1a on the base 4, the associated weight force ensures that the spring 7 in the exemplary embodiment according to FIG Figures 1 to 4 is compressed and in the variant after the figure 5 undergoes a stretch. Because in this process, the base 4, starting from the rest position, performs the actuating movement T, which, according to the exemplary embodiment, corresponds to the arrow illustration in FIG 2 is coupled to a downward movement of the base 4 and consequently of the connecting rod 6 connected thereto.

The connecting rod 6, which is moved downwards, in turn ensures via the head-side joint 11 and the holding arms 5 connected here that the holding arms 5 can also be moved from their previously occupied open position according to the position against the force of the spring 7 2 move to the closed position. At the same time in this case the spring 7 in the variant according to Figures 1 to 4 compressed until the two retaining fingers 10 protruding from the retaining arms 5 fix the instrument neck 1b properly. In the variant after the figure 5 the spring 7 lengthened there during this process again ensures that the instrument neck 1b is held in place properly and detachably.

Not shown is the further possibility of designing the retaining arms 5 to be adjustable in principle, generally transverse to the longitudinal extension of the connecting rod 6. In this way, the retaining arms 5 or the distance between the retaining fingers 10 can be adapted to differently designed instrument necks 1b. It is conceivable in the simplest case, for this purpose relevant holding arm 5 or the holding plates to be designed in two parts and telescopically similar to the telescoping connecting rod 6 . In the variant after the figure 5 it is conceivable that the holding fingers 10 can be displaced relative to the scissors joint 13 in the transverse direction compared to the longitudinal extension of the connecting rod 6 in order to be able to make the adjustments described.

In addition to the basic possibility of being able to adjust the two holding arms 5 and thereby adapt them to different instrument necks 1b, the invention also provides the option of additionally or alternatively also making the base 4 adjustable. This can be done in that the two support fingers 8 connected to the base 4 are designed such that their distance can be changed. In addition, the base 4 can also be expanded by one in the figure 5 Pivot or rotate axis 14 to be recognized. A multi-part design of the base 4 with two arms pivotably connected to the axis 14 and having the support fingers 8 at the ends is also conceivable. In this way, the base 4 can be adapted, for example, to different and in particular asymmetrically designed shapes of the instrument body 1a.

A slightly modified embodiment of the example after figure 5 show the 6 . In this case, too, the two holding arms 5 can be adjusted transversely to the longitudinal extent of the connecting rod 6 . As a result, the holding arms 5 or, in this context, extensions 5′ of the holding arms 5 and with them the holding fingers 10 can again be adapted to differently designed instrument necks 1b. These are within the scope of the embodiment according to the Figures 6A and 6B the retaining fingers 10 are each attached at the end of the extension 5' or of the retaining arms 5.

It can be seen that the extensions 5' are each connected at the ends to the holding arms 5 coupled to the telescoping connecting rod 6. A scissors joint 13 is again implemented in this case, with the help of which the retaining fingers 10 can be displaced in the transverse direction in comparison to the longitudinal extent of the connecting rod 6, as can be seen when comparing the open state according to FIG Figure 6A with the closed and the guitar neck or instrument neck 1b defining state in the Figure 6B recognizes. The in the variant according to the Figures 6A and 6B also realized spring 7 is not explicitly shown here, may rather find an arrangement hidden behind the anchor element 3 and is shown in the illustration according to FIG Figure 6A example lengthened, so that the two support arms 5 in the state after Figure 6B can fix the instrument neck 1b as described by the spring force.
