Description

The invention relates to a holding device for a stringed instrument, in particular for a guitar, which has a housing with two fork-shaped holding arms, wherein the holding arms have a fastening portion and a holding portion which are interconnected via at least one angled lever portion, wherein at least one holding arm around a The longitudinal axis of the mounting portion is rotatable.

Such holders are used to hold sensitive string instruments safely. Stringed instruments are instruments that have a sounding body, a neck and a head. In a guitar, for example, the part of the guitar is called neck, on which the strings of the guitar are tapped to change their effective for sound production length. With the head becomes the Part designated, are usually provided on the clamping screws or the like for tuning the guitar.

Stringed instruments are usually sensitive to mechanical stress. For storing the stringed instruments therefore secure holding devices are necessary.

Out DE 195 07 681 C2 a guitar holder is known, which has a mounting housing to which two retaining arms are attached, which protrude in the manner of a fork with two prongs and form a support for a guitar head. In order to adjust the distance of the support arms to each other to the width of the guitar neck, at least one support arm on the mounting housing in the direction of the other arm is arranged to be movable. For this, the movable support arm is mounted with an end portion of an angled holding portion on the mounting housing and pivotable about the end portion with a circular motion.

In this construction, the position of the holding arms is held by means of friction-increasing means. For threading the guitar, it is then usually necessary first to increase the distance between the holding arms by hand. The instrument is held almost automatically. The support arms are moved towards each other by the weight of the instrument acting on the support arms via the head of the instrument. To remove the instrument, a slight lifting of the instrument is sufficient, wherein the support arms are moved a little by the friction between the support arms and the neck, so that the distance between the support arms again increases slightly.

However, this distance is usually so small that the re-insertion of the instrument is difficult. It is therefore necessary again first to increase the distance between the holding arms by hand. The same is of course also the case if another instrument is to be introduced into the holding device, which has a neck with a larger width. A user therefore usually requires a free hand to bring his instrument into the fixture.

Out EP 1 494 207 A1 For example, a wall holder for a guitar is known in which at least one holding arm is movably guided in a groove and is movable toward a second holding arm. In this case, a return device can be provided for moving back the movable support arm, which generates a translational return movement of the support arm. An implementation of the restoring device is not disclosed.

The invention is based on the object to provide a holding device in which a stringed instrument is easily introduced.

According to the invention, this object is achieved in a holding device of the type mentioned above in that at least one holding arm has a restoring device which acts eccentrically on the attachment portion.

By the restoring device so a restoring moment is introduced into the holding arm. This moment However, it must not prevent a secure hold of the instrument in the holding device. The restoring device is thus adapted to the fact that even with a light instrument, the retaining arms can be moved toward each other, but the restoring force is still sufficient to increase the distance of the support arms to each other again after removing the instrument. Due to this configuration, the holding device has a defined rest position in which the holding arms are widely spaced from each other. This position automatically retracts the holding device after removing an instrument. The insertion of an instrument is thus easily possible, even if the neck of the new instrument is wider than that of the instrument, which was previously held in the holder. This results in a simplified handling.

Preferably, the fastening portions extend into the housing, wherein the restoring device is arranged in the housing. As a result, the restoring device is protected, for example, from contamination by the housing. At the same time results in a harmonious, visual impression, which is not disturbed by the return device, since it is covered by the housing. The mounting portions may be fastened in the housing, for example by means of snap ring. An expensive storage is usually not necessary. It is only important that the mounting portions are rotatably mounted. In this case, a possible rotation angle can be limited for example by stops which are arranged in the housing.

Preferably, the restoring device is designed as a spring. This represents a relatively inexpensive solution that is also very low maintenance. Since the restoring device acts eccentrically on the attachment portion, the spring may be formed as a simple compression or tension spring. But it is also possible to form the spring as a torsion spring. The dimensioning of the spring takes place in view of the required restoring force.

Preferably, only one return device is provided, which acts eccentrically on both mounting portions. It is then no longer necessary that the return device is also fixed in the housing. At the same time it is achieved that both retaining arms are moved simultaneously, wherein the force generated by the return device is evenly distributed to the two support arms. Depending on the shape of the head, a symmetrical or asymmetrical movement of the holding arms takes place. The number of necessary components is minimized, so that the production is inexpensive.

Advantageously, an opening is arranged in the attachment portion perpendicular to the axis of rotation, in which a pin is arranged, wherein the restoring device is attached to one end of the pin. As a result, a reliable and easy attachment of the return device is possible. The opening may for example be designed as a bore. The pin can be held for example by means of nut and snap ring within the opening. It is also possible to provide the opening with an internal thread into which the pin, the then must have a corresponding external thread, is screwed into it. The length of the pin, measured from the axis of rotation to the point at which the restoring device is attached, is then the lever arm, via which the restoring moment is introduced. The pins can be pressed in a particularly simple embodiment and in the opening and / or glued.

It is particularly preferred that in a rest position of the support arms, the pins are arranged parallel to each other. As a result, an equal holding torque is exerted on both retaining arms in the rest position.

Preferably, an angled extension is in each case arranged at one end of the holding sections, wherein the extensions can be pivoted toward one another. By the movement of the support arms towards each other, which is caused by the weight of the instrument, which rests with its head on the support arms, so are the angled extensions, which are located at the ends of the two holding portions of the support arms, pivoted toward each other. A removal or falling out of the instrument is then reliably prevented by the extensions. A secure hold of the instrument is guaranteed.

The holding arms preferably have a coating. This cover should be made of an anti-slip material such as PP-EPDM. The coating then serves as a further protection against slipping out of the instrument, on the other hand, but also because of its elasticity for gentle Holding the instrument. The coating may be formed as an injection molded part, which is sprayed onto the retaining arms.

It is particularly preferred that the extension is formed integrally with the coating. The extensions can be made so very inexpensive. Since the instrument is already held by the holding arms, it is also not necessary that the extensions can produce a large holding power. Rather, it is advantageous that they are compliant, since this reduces a risk of injury.

In a preferred embodiment, the housing is formed closed, with an upper side and / or a lower side having a lid. The restoring device arranged within the housing is completely surrounded by the housing, so it is housed very protected. Nevertheless, a lid arranged on the top and / or underside allows access to the restoring device. The assembly of the return device is simplified.

Preferably, the housing is pivotally connected to a mounting geometry. The attachment geometry is used to attach the holding device, for example, on a stand or on a wall. If the housing is now pivotably connected to the attachment geometry, the housing can be pivoted so as to save space such that the support arms run parallel to the wall or to the stand. If the holding device is connected, for example via the attachment geometry, to a transportable stand, this makes it possible Swiveling the case saves space.

In Fig. 1 a holding device 1 is shown for a stringed instrument that can be attached to a stand or tripod. The holding device 1 has a housing 2, on which two retaining arms 3, 4 are pivotally mounted. The holding arms are in the manner of a fork with two prongs. The holding arms each have a fixing portion 5, 6 and a holding portion 7, 8, which are connected to each other via an angled lever portion 9, 10. The holding portion 7, 8 serves to support a head of a stringed instrument, such as a guitar. The housing 2 is pivotally connected via an axis 11 with a mounting geometry.

The holding arms 3, 4 are rotatable about their attachment portions 5, 6. The holding sections 7, 8 thereby carry out a circular movement. In this case, a distance between the holding sections 7, 8 changes during a pivoting or rotational movement of the holding arms 3, 4. This is in Fig. 2 shown.

At the in Fig. 2 illustrated embodiment, the support arms 3, 4 each have an extension 13, 14. With solid lines while a rest position of the support arms 3, 4 is shown, which occupy these when no instrument is held. Shown dashed is a holding position of the support arms 3, 4. While the extensions 13, 14 in the rest position almost parallel to each other, they face each other in the holding position. This prevents removal of the instrument.

The housing 2 is provided with a lid 15 which closes the top of the housing 2. The mounting geometry 12 has a receptacle 16 for a cylindrical body. This can for example be a tripod.

In another preferred embodiment, incorporated in the Fig. 7 to 11 is shown, the holding device 1 is designed as a wall mount, wherein the housing may be integrally formed with an open back 31. The open back 31 is then the wall-facing side. The housing 2 is then closed in the mounted state of the wall. The attachment geometry can then be formed in the simplest case as holes 32 through which, for example screws are feasible to secure the fixture 1 to the wall.

In Fig. 3 is the holding device according to Fig. 1 shown with removed cover 15. It can be seen that the fastening sections 5, 6 extend into the housing 2. The two attachment portions 5, 6 are connected to each other via a return device 17, which acts eccentrically on both attachment portions. The restoring device 17 is designed as a spring and attached to pins 18, 19, which are arranged on the mounting portions 5, 6. The return device 17 ensures after removing an instrument from the holding device for a return of the retaining arms 3, 4 in the rest position.

An end face 20 of the housing 2, through which the mounting portions 5, 6 of the support arms 3, 4 is guided, has a relatively large wall thickness, so that a secure mounting of the support arms 3, 4 is ensured. The holding arms 3, 4 are held in the axial direction within the end face 20 by means of pins 21 which are guided in grooves 22, 23. A pivoting of the support arms 3, 4 is thereby admitted over a predetermined angle, which is determined by the length of the grooves 22, 23. It can also be provided lateral stops that limit the possible angle of rotation of the support arms 3, 4. This also defines the position of the retaining arms in the rest position.

In Fig. 4 is a sectional view of the holding device according to Fig. 1 shown, wherein the cutting plane in Fig. 1 marked with A. The holding arm 4 is provided with a coating 24 made of an anti-slip elastic material. This coating is formed for example as an injection molded part, which is sprayed onto the support arm 4. The holding arm 4 may have a core which may be formed as a bent part, in particular as a wire bending part. Integral with the coating 24 of the extension 14 is formed. The holding arm 3 is designed accordingly.

The pin 19 is guided through an opening 25 in the mounting portion 6 of the support arm 4 and held with a nut 26, which cooperates with a hexagon 27. The hexagon 27 can be designed as a nut be screwed onto the pin 19. However, the hexagon 27 may also be formed integrally with the pin 19. This is for example the case when the pin 19 is made of hexagonal material, for example by turning machining. Other attachment possibilities of the pin 9 are conceivable.

The housing 2 is connected via the axis 11 pivotally connected to the mounting geometry 12. It is thereby possible to pivot the housing 2 together with the holding arms 3, 4 by almost 270 °. As shown in Fig. 4 this pivoting is counterclockwise. By pivoting, it is possible to bring the holding arms 3, 4, for example, during transport in a position in which their longitudinal direction is parallel to the receptacle 16. As a result, a particularly space-saving transport is possible.

In Fig. 5 a further sectional view of the holding device 1 is shown, wherein the sectional plane in Fig. 1 marked B. It can be seen that the large wall thickness of the end face 20 not only serves to guide the holding arms 3, 4, but also to the lid 15 and a further cover 28 which is arranged on an underside of the housing 2, by means of a positive fit to fasten. In the receptacle 16, a cylinder tube 29 is received and fixed by means of a Spreizniet 30. Instead of a Spreizniets example, a screw can be used or an undercut on the receptacle 16 may be provided. The cylinder tube 29 may for example belong to a tripod.

In Fig. 6 the holding device 1 is shown in cross-section, wherein the cutting plane in Fig. 1 marked with C. The holding device 1 is shown in a rest position in which the pins 18, 19 parallel to each other.

In these embodiments, only one common restoring device for both retaining arms 3, 4 is shown. It is also possible to provide a separate return device for each holding arm 3, 4, which does not necessarily have to be designed as a tension spring. However, it is important that the return device eccentrically on the mounting portions 5, 6 of the support arms 3, 4 acts, as in Fig. 6 easy to recognize. As a result, a restoring moment is exerted on the retaining arms 3, 4.

In the holding device 1 according to the invention, the holding arms 3, 4 are fixed to the housing 2 such that a force acting on the holding arms 3, 4 in gravity driving force, which is for example generated by an instrument which is introduced into the holding device 1, in a movement of Holding arms 3, 4 is implemented, with which the distance between the holding portions 7, 8 of the holding arms is reduced. If no driving force acts more, so after removing the instrument, the support arms 3, 4 are brought by means of the return device 17 back to its rest position. The introduction of a new instrument is thus easily possible.

The holding device according to the invention can be used not only for guitars, but also for other stringed instruments such as a banjo, a ukulele, a balalaika or for stringed instruments such as violins, violas or cellos. The only restriction is that they must have a neck which must have a head widening in relation to the neck.

In the embodiments according to the Fig. 1 to 6 the holding device is provided with a mounting geometry for attaching the holding device to a stand or tripod. In an embodiment of the holding device as a wall mount, as shown in the Fig. 7 to 11 is shown, the attachment geometry can be made much simpler. A particularly simple embodiment results from the fact that the mounting geometry is formed integrally with the housing, being dispensed with a pivoting of the housing relative to the mounting geometry.

In the preferred embodiment according to Fig. 7 the attachment geometry is formed as holes 32. These are arranged in a flange-like widening of the housing 2. In this example, four holes 32 are provided. The number of holes 32 is almost arbitrary. Due to the widening of the housing 2, the holding device 1 has a large contact surface on a wall, not shown. The housing 2 is provided with an open rear side 31 on the side against which it is intended to rest against the wall. It is also possible to form this back also closed, with an open Back 31 but material is saved. Incidentally, the embodiment of the holding device according to Fig. 7 designed accordingly as in the embodiments of Fig. 1 to 6 , The same parts are therefore provided with the same reference numerals.

In Fig. 8 it can be seen that in the housing 2 reinforcing ribs 33 are arranged. This makes it possible, the housing 2 easily and yet sufficiently stable form.

In Fig. 9 It can be seen that can be dispensed with the lower lid 28 in the formation of the holding device 1 as a wall mount. Due to the open rear side 31, it is nevertheless possible in a simple manner to fasten the restoring device 17 to the fastening sections 5, 6 of the retaining arms 3, 4. Optionally, can be dispensed with the lid 15, so that the entire housing 2 can be made of a part, for example as an injection molded part.

Fig. 10 shows the holding device 1 in a rest position, ie in the position which occupy the support arms 3, 4, when they are not loaded.

In Fig. 11 is now a position of the holding arms 3, 4 shown, which occupy these under load. It can be seen that the distance between the holding sections 8, 9 of the holding arms 3, 4 is reduced. At the same time, the extensions 13, 14 pivot toward one another, so that falling out of the instrument is almost impossible.

The holding device for stringed instruments according to the invention can be adapted to different tasks by simply adapting the attachment geometry and / or the housing 2. As has been shown, this makes it readily possible to form a holding device as a wall mount or as a holder for a stand. If the holder according to the invention is used in conjunction with a stand, it may be possible to dispense with additional holding elements on the stand, which serve as a support for the sound body, since the holding device already ensures a secure hold of the instrument. It can be used by simply erected stand, with no individual adaptation to different instrument sizes is required.
