Description

The present invention relates to a legrest for a stringed instrument, in particular for a guitar, and a stringed instrument with a legrest.

background

Various guitar supports and playing aids for guitars or similar stringed instruments are known from the prior art. Especially in the field of classical guitar playing traditionally called footstools are used, by means of which a seated player brings one of his legs in a slightly raised position to raise the guitar or the relevant string instrument in a suitable position for musical performance. However, placing a foot on a footstool forces the player's body into a completely unnatural posture, which can lead to cramps and tension in the back and shoulder muscles.

One in the DE 298 18 406 U1 described guitar support is fastened with screw-down jaws on the bottom and on the frame of the guitar. On the one hand, such jaws damage the delicate paint of the guitar. On the other hand, they can leave marks in the wood of the ceiling. The pinching of the guitar body ultimately leads to a resonance damping of the guitar and thus affects their acoustic properties.

Furthermore, from the DE 200 21 500 U1 a support for a guitar with an essay, a support member and a fixation known. The fixation holder includes a hinged on the support hinged suction cup carrier with suction cups, which are pressed against the frame of the guitar. The frame enclosing the guitar body has a wide swinging or curved design. Suction cups therefore often find no ideal support on the frame and must additionally be secured with adhesive films.

Such a connection to the frame of the guitar usually does not provide a sufficiently strong and torsionally rigid connection between the guitar body and the legrest. In use, therefore, the guitar usually wobbles. In addition, the attachment of the support to a leg portion of the player facing lower frame also leads to a significant resonance damping of the guitar. This sounds increasingly quieter with a support arranged on it. Furthermore, the suction cups attached to the lower frame generate unpleasant and clearly perceptible background noises when the player moves.

The in the DE 200 21 500 U1 described support for a guitar also has a fairly complex structure. It consists of several pivotable or freely positionable components, so that the use of the guitar support in practice is quite expensive.

From the US 6,031,167 A For example, an L-shaped pad is known for use with a stringed instrument. The US 2015/0179155 A1 describes a guitar carrier with multiple releasable fasteners. The JP 2004-295054 A describes a stand for a guitar with a suction cup and a curved base plate. From the US 6,040,509 A Furthermore, a can be arranged on a guitar frame with a pivotally mounted thereon plate is known.

Many well-known guitar supports also have in common that they are completely unsuitable for guitarist hands, especially for the fingernails of guitarists. It is often necessary to operate set screws or heavy metal plates, which is always accompanied by a risk of fingernail fracture. In addition, the previously available on the market guitar supports hardly an attractive appearance, so that their use for performances and concerts is usually out of the question. In the field of classical guitar, the musicians therefore mostly rely on the well-tried footstool and accept the disadvantages described in the introduction.

In contrast, the present invention is an object of the invention to provide an improved legrest, which reduces the handling or aesthetic appearance, in terms of their functionality and in terms of their acoustic interaction with a stringed instrument the disadvantages of the prior art described or completely overcome. This should allow a fatigue-free pleasant playing the guitar and make common footstools dispensable. The leg support should be characterized by a particularly shapely design and an attractive external appearance, so that it also gets into the performance practice. It should also be characterized by a simple, yet robust and space-saving design and have only minimal impact on the acoustic properties of the guitar.

This object is achieved with a legrest for a stringed instrument according to claim 1 and a equipped with such a legrest stringed instrument according to claim 8. Advantageous embodiments are each the subject of dependent claims.

The provided according to the invention legrest for a stringed instrument, in particular for a guitar, has a support plate. This has on a side edge a leg recess for receiving a thigh of a player of the stringed instrument. Furthermore, at least two suction cups protruding from a plane of the carrier plate are arranged on the carrier plate. These are used for releasably securing the support plate to the rear wall of the stringed instrument. By means of at least two or even three or four suction cups, the carrier plate can be fastened several times to the rear wall of the stringed instrument. In this way, the weight of the guitar can be transmitted to the carrier plate via a plurality of connection points.

The detachable arrangement of a plurality of suction cups on the rear wall of the guitar is further advantageous insofar as that the rear wall of the guitar is typically configured relatively flat and planar. This allows a particularly good and durable attachment of individual suction cups on the rear wall. The connection of the legrest to the guitar preferably takes place exclusively via the at least two or more, that is typically via at least three or four suction cups with the carrier plate. In that regard, no structural adjustments to the guitar are made.

The detachable attachment of the carrier plate by means of suction cups can be varied continuously and adapted individually to the needs of the player of the stringed instrument. Above all, suction cups are also very gentle on the surface of the body, in particular on the back wall of the stringed instrument. There are no signs of damage to the instrument.

By means of at least two suction cups projecting from the plane of the carrier plate and with their flexible cups extending substantially parallel to the plane of the carrier plate, an arrangement of the carrier plate can be achieved substantially parallel to the rear wall of the body of the stringed instrument. The frame of the string instrument remains completely connection-free for leg or guitar support. With proper use of the legrest, the lower frame of the stringed instrument will even be spaced from the thigh of the player. The resonance behavior of the stringed instrument can thereby even be improved. By the frame of the instrument thanks to the legrest according to the invention has no direct contact with the body of the player, the resonance attenuation of the instrument is reduced to a minimum.

The fact that the approximately rectangular or oval-shaped support plate is aligned parallel to the rear wall and can be arranged on the rear wall of the body of the stringed instrument, the support plate, thus provide the entire leg support a kind of double soundboard. By the rear wall of the body of the stringed instrument is only selectively, namely connected only at the provided with Saugnäpfen points with the support plate, the remainder and thus the vast majority of the rear wall remains contact-free to the support plate. The back wall of the body can swing quite freely in this respect. Those vibrations can be reflected by the typically continuous and closed designed support plate forward, toward the body. The gap between the body and the support plate can act as a further resonance chamber insofar and the resonance behavior, thus the entire acoustic properties of the stringed instrument either minimal impact or even improve.

The carrier plate is also formed in one piece. It is essentially rigid and just designed. The support plate may be made of wood, for example. It can consist of a multi-ply wood with embedded threaded sleeves. Thus, the entire legrest may consist essentially of the carrier plate and suction cups arranged thereon. The leg rest has no pivotally mounted or removable links, which makes the handling of the leg rest particularly simple.

According to a further embodiment, at least four suction cups spaced from each other are arranged on the carrier plate. By at least four attachment points formed by suction cups are provided, the weight of the stringed instrument can be transmitted relatively homogeneously and distributed over the rear wall of the stringed instrument on the support plate of the legrest. The legrest and the string instrument combine to form a unit. By means of several suction cups creates a rigid connection between the support plate and the rear wall of the stringed instrument. The leg rest and the string instrument can thus follow any movement of the player without torsional moments, additional relative movements or thrust forces between the leg rest and the string instrument.

In addition, the center of gravity of the composite legrest and string instrument shifts towards the player's body. The player must therefore draw the string instrument only to a much lesser extent actively to his body. The support area, thus the leg recess of the support plate can come to lie in particular close to the player's step. In particular, the carrier plate can be aligned almost vertically when used correctly in a playing position of the stringed instrument. This effectively prevents the stringed instrument from sliding forward at an angle.

The connection of the legrest to the rear wall of the body of the stringed instrument also presents itself as an aesthetically particularly happy solution, since the legrest is barely perceptible from the front. Only with a lower end portion protrudes from the underside of the body of the stringed instrument. If the carrier plate is held in a color corresponding to the player's clothing, it is barely perceptible in a musical performance. This should increase the acceptance of such a legrest significantly. The already described connection of the support plate on the rear wall of the stringed instrument also leads to the fact that the stringed instrument can be kept balanced in a quasi-floating manner over the leg, in particular above a thigh of the player.

Due to the changed center of gravity of the composite stringed instrument and legrest, the stringed instrument, without having to be held in the least, almost quasi independently and permanently held by the support in a comfortable for the player elevated position.

According to a further embodiment, the support plate on at least four, six, eight or even more spaced apart attachment points for each one of the suction cups. In other words, typically more attachment sites than suction cups are provided on the carrier plate. In this way, individual suction cups can also be attached to different attachment points of the support plate. This results in correspondingly different connection and connection points on the rear wall of the stringed instrument. In particular, the acoustic properties of the body of the stringed instrument may vary due to the manner of securing a plurality of suction cups to individual selected attachment locations of the rear wall.

By providing a multitude of individual fastening points, the legrest can not only be individually adapted to the most varied back wall geometries of stringed instruments. It is therefore also possible to influence the resonant properties and thus the acoustic behavior of the stringed instrument in the most advantageous manner possible by different equipping individual attachment points of the support plate with suction cups.

According to a development thereof, a threaded sleeve let into the carrier plate is provided on at least one of the attachment points of the carrier plate. The threaded sleeve can also enforce the carrier plate completely. Advantageously, an axial end of the threaded sleeve closes flush with the plane of the support plate, so that the threaded sleeve does not protrude from the support plate. By providing a plurality of attachment locations in individual attachment areas provided for the placement of a sucker, one of several available attachment locations may ultimately be selected for the actual attachment of a sucker in a particular attachment area. In this way, the legrest is also customizable to predetermined geometric or acoustic characteristics of the stringed instrument.

According to a further embodiment, at least one of the suction cups has an elastic cup with a threaded pin projecting outwardly from a cup bottom. By means of the threaded pin of the respective suction cup is typically screwed into the provided at an attachment point of the support plate threaded sleeve. In this case, it is provided in particular that the threaded pin extends substantially perpendicular to the cup bottom to the outside, ie facing away from the concave cup geometry. A suction cup arranged in this manner on the carrier plate typically extends with its cup edge substantially parallel to the plane of the carrier plate.

The use of threaded cups provided with grub screws and the provision of several, each provided with a threaded sleeve attachment points over the surface of the support plate, allows an individual configuration of the legrest for a variety of stringed instruments.

According to a further embodiment, at least one of the suction cups is adhesively secured to the support plate. Thus, one or more suction cups can be attached either directly by means of their cup bottom to the support plate adhesive. It is also conceivable that at least one or more threaded sleeves are adhesively or adhesively secured to the support plate. The threaded sleeves or the like fastening means can also protrude from the plane of the support plate. As an alternative attachment means are basically any types of mounting base in question, where each individual suction cups are preferably releasably fastened. For example, the individual attachment points can each be provided with a mounting clip to which a correspondingly designed counterclip of a suction cup can be detachably fastened.

The substantially planar and newly designed legrest, despite its size, which can be approximately in the range of the outer dimensions of the body of the respective stringed instrument, particularly easy to be carried in a case or a case for the stringed instrument. It is even conceivable that the leg rest in about a 90 ° rotated arrangement aligned parallel to the longitudinal extent of the body of the stringed instrument fastened to the rear wall of the body and so far far covering with the body in a case for the stringed instrument together with the stringed instrument is stowed. In that regard, no separate bag is required for carrying the legrest.

According to a further embodiment, the support plate is provided with a cushion at least in the region of the leg recess. The pad may for example have a natural or synthetic rubber material or a foam, so that the support plate in the leg recess as well as possible and can cling to the thigh in a way that is comfortable for the player. For the pad is in particular a sponge rubber, ie an open-cell and elastic material, for example, chloroprene, natural rubber or similar materials in question. Other upholstery configurations provide, for example, an elastic and compressible fabric, a knitted fabric or a fiber material. For example, the pad may have a felt. Also leather upholstery and any combination of all mentioned materials in question, such. Felt leather and / or foam combinations.

According to a further embodiment of the legrest at least provided with the suction cups front of the support plate is provided with a coating. As a layer material, for example, a grinding lacquer or a multi-layer lacquer, in particular a so-called piano lacquer can be provided. Such a coating gives the leg support a particularly high-quality appearance, which appeals equally to the aesthetic feeling of the player, listener or spectator alike.

Finally, according to a further aspect, a stringed instrument with a body and a neck is provided, wherein on a rear wall of the body a legrest described above with at least two suction cups is detachably arranged. The stringed instrument can be designed in particular as a guitar, furthermore as an acoustic or classical guitar.

Detailed description

In 1 is a player 1 a presently designed as a guitar string instrument 12 shown schematically. The stringed instrument 12 has a body 14 and a long neck 20 on, along which the only schematically illustrated and at a bridge 18 held strings are stretched. In 1 is the ceiling facing the viewer 24 or front of the body 14 with a sound hole 26 Mistake. On the back wall 16 of the body 14 is a legrest 10 by means of several suction cups 31 . 32 . 33 . 34 detachable and infinitely adjustable arranged.

In the 3 Legrest shown in isolated form 10 has a substantially planar, in the present embodiment, almost rectangular designed carrier plate 30. A lower margin 38 the substantially flat and rigid designed carrier plate 30 has a leg recess 35 by means of which the support plate 30 in a nearly vertical orientation on a thigh of a seated player 1 is shut off. The opposite upper side edge 36 the support plate 30 is extensively elongated or rectilinear designed. This also applies to the lateral side edges of the carrier plate.

The concrete geometric design of the support plate 30 However, it can also differ from the nearly rectangular geometry shown here and vary as desired. The overall dimensions of the carrier plate, in particular the height of the carrier plate is typically slightly larger than the width of the guitar body, that is, the extension of the body 14 perpendicular to the longitudinal extent of the neck 20 , In this way it is ensured that the lower portion of the support plate 30 with the leg recess 35 to a certain extent from the bottom of the body 14 of the string instrument 12 protrudes. The stringed instrument 12 can thus in a relation to the thigh 2 of the player 1 elevated position on the thigh 2 are supported.

The leg recess 35 is an advantage with a cushion 40 Mistake. For aesthetic reasons, this can also extend over the entire lower margin of the page 38 the support plate 30 extend. Like from the 2 and 3 shows, stand the suckers 31 . 32 . 33 . 34 at least with their wells off the plane 39 the carrier plate 30 out.

In this way, in a proper attachment of the support plate 30 to the rear wall 16 of the body 14 between the back wall 16 and a front side 49 the carrier plate 30 a gap 50 formed, which can act as a further resonance chamber. The construction height or the depth of the individual suction cups 31 . 32 . 33 . 34 essentially determines the size of that gap 50.

The carrier plate 30 may for example be formed of a multi-ply wood but also of a plastic. In particular, the front can 49 be provided with a coating 48, the support plate 30 at least in its lower and from the corpus 14 of the stringed instrument 12 protruding area gives a particularly appealing aesthetic appearance.

The position of the individual suction cups as well as the number of suction cups 31 . 32 . 33 . 34 can depending on the specific design of the legrest 10 and depending on the string instrument 12 vary individually. In the present embodiment, a total of four over the surface of the support plate 30 distributed suction cups 31 . 32 . 33 . 34 intended. Two of the suckers 31 . 32 are here in the region of the outer ends of the upper side edge 36 intended. The attachment points 41 for the two suckers 31 . 32 are chosen such that their distance from the upper side edge 36 and the adjacent lateral side edges is less than the radius of the respective suction cup 31 . 32 , In the end, the suction cups stand 31 . 32 at least partially from the outer contour of the carrier plate 30 out.

The two other suckers 33 . 34 are arranged approximately at the level of the lower third of the support plate 30. They are partially visible from the outer contour of the support plate 30. In this way, the greatest possible distance between the individual suction cups 31 . 32 . 33 . 34 on the back wall 16 of the body 14 of the stringed instrument 12 formed, which is responsible for the mechanical and rigid connection of legrest 10 and stringed instrument 12 proves to be advantageous. In addition, by a maximum distance of the suction cups 31 . 32 . 33 . 34 Achieve among themselves the best possible acoustic end result when using the legrest as intended.

In 3 is also the example of the suction cup 34 illustrated that a designated for that suction cup 34 mounting area 42 at the bottom of the rear wall 16 of the body 14 not just one, but several attachment points 41 . 43 which, as in 3 and 2 shown with a vertically oriented legrest 10 are substantially vertically spaced from each other. Those attachment points 41 . 43 each have one in the carrier plate 30 embedded threaded sleeve 44, in which the relevant and with a threaded pin 46 provided suction cup 34 screwed in as required and thus at different positions on the support plate 30 is fastened. As in 2 shown schematically, the respective suction cup 34 a cup bottom 34a on, from which the threaded pin 46 protrudes substantially perpendicular to the outside.

By doing that individual attachment areas 42 the carrier plate 30 is provided with a plurality of fastening points 41, 43, which are configured here in the form of threaded sleeves, the support plate 30 , hence the entire legrest 10 as needed to the needs of each player 1 be adjusted.

The substantially planar and one-piece design of the leg support with a number of suction cups arranged thereon 31 . 32 . 33 . 34 can not only be solved in a particularly simple manner on the rear wall 16 of the body 14 , but also in case of need from the corpus 14 be removed. It is possible in particular, the legrest 10 with its carrier plate 30 about 90 ° to rotate, so that the entire outer dimensions of the support plate 30 within the outer border, thus within the frame 22 of the body 14 comes to rest and in such, not shown, configuration on the body 14 attached together with the string instrument 12 can be stored in a case. A separate entrainment of the legrest outside of the case for the stringed instrument 12 is therefore unnecessary.
