Definitions

  • the invention relates to a legrest for a guitar or a guitar-like instrument, which is played while sitting in front of the instrument player and under support on the thigh of the instrument player.
  • the user When playing classic guitars while seated, the user must support the instrument on his thigh.
  • the guitar is at the right height and in the correct position with respect to the upper body of the instrument player, therefore, so-called footstool or footstools with a sloping support surface were known.
  • Such tonebänke represent a rather shaky affair, they must also be cumbersome and additionally transported to each of the guitar and are relatively bulky and heavy elements.
  • leg supports for guitars have been developed in the prior art in which a support has been attached directly to the guitar and a support surface has been provided for abutment against the thigh of the user.
  • a guitar support in the form of an L-shaped, rigid plastic element known, which can be attached via suction cups on the side wall or frame of the guitar is.
  • This leg rest is a bulky, rigid element that has to be transported separately from the guitar. The support must be removed to transport the guitar.
  • the holder is relatively unstable about suction cups, since the suction cups can easily be detached from the frame of the guitar with lateral forces.
  • the suction cups and thus the loaded with compressive forces support points of the leg support are provided in areas of the frame, which are very sensitive. Due to the high loads in the middle region of the frame, the guitar can be damaged, and not least, this affects the acoustic properties of the body of the guitar.
  • leg rest for a guitar is formed from a triangular support element made of sheet metal, which is provided with U-shaped designed holding brackets for laterally gripping the guitar body.
  • This legrest is a relatively bulky element that leads to difficulties during transport as well as during handling.
  • the support of the leg rest on the guitar is unstable via the U-legs, as the guitar may slip into position in the leg rest. This can damage the guitar.
  • this legrest rests on the frame of the guitar in areas that are not only sensitive to compressive stresses, but also for the acoustic sound characteristics of the guitar body are relevant. An impairment of the sound behavior of the instrument by the leg support is therefore given.
  • legrest for guitars, which in the German Offenlegungsschrift DE 197 25 157 A1 is described, the support of two hinged together, straight boards is formed, which are connected via a webbing, the extension of which also serves to attach the support to a lower Einhakelement or knob of the guitar. Due to the one-sided attachment of the legrest by means of the belt results in a single, highly loaded support point on the frame of the guitar, the resulting pressure forces through the Lever effect of the abbragenden board and the belt adjacent to the thigh is reinforced. The high pressure loads on the frame at a single point can damage the guitar and have a significant impact on the acoustics of the guitar's body.
  • this type of attachment is extremely unstable, and a lateral tilting or slippage of the legrest with respect to the guitar is not avoided.
  • the guitar is also in a wrong position for the instrument player, as the guitar is far too high relative to the body.
  • a hole must be made in the lower block, which is unthinkable with valuable instruments.
  • leg supports known in the art thus proved to be either extremely impractical or inefficient to handle either.
  • the known leg supports were conceivably unstable in their fixation on the guitar body and affected due to the unfavorably positioned investment points on the delicate frame of the guitar, the sound characteristics of the instrument and could even lead to damage to the guitar in the worst case.
  • the legrest for sitting guitar playing according to the invention has a leg rest with a support surface for abutment against the thigh of the instrument player on and a guitar-side support base member which is releasably secured to a frame of the guitar. Further, an erection element is provided, which is hingedly connected to the support base member via a hinge and protrudes in use position approximately perpendicularly from the support base member, wherein the support base member according to the invention has a substantially corresponding to the shape of the frame, curved shape and wherein the positioning element as well how the leg rest when not using the leg support is substantially foldable or stowable in the plane of the support base member.
  • the legrest has a shape that runs relatively close to the frame of the guitar and protrudes only insignificantly from the side wall or frame of the guitar in the folded-in state of the positioning element and leg rest ,
  • the legrest according to the invention can therefore remain fixed for transport to the guitar and be housed together with the guitar, for example in a guitar case.
  • the curved shape of the support base member provides a very stable and substantially only pressure-loaded support of the leg support on the guitar sound body. The support forces at corresponding attachment points are distributed at convenient and spaced areas of the frame of the guitar.
  • the sensitive middle region or the waist region of the guitar can be kept free of supporting forces in this way, so that an impairment of the acoustic behavior of the sounding body is largely avoided.
  • the legrest according to the invention forms a very narrow and therefore less conspicuous construct, which impairs the visual impression of the guitar player as little as possible, especially during concert performances.
  • the curved shape of the legrest is a slightly S-shaped curved shape.
  • simply curved shapes are provided, each corresponding to the shape of the side wall of the instrument body.
  • the raising element as well as the leg rest is designed to be folded or stowed substantially in the plane of the support base member, the user can either play with or without support on the thigh without the leg support forms a disturbing, protruding element.
  • the S-shaped curved shape of the legrest or its support base member has the advantage that it allows for the game play optimized and yet extremely effective positioning of the leg support for stable attachment.
  • the player is provided with a leg support surface substantially in the area of the lateral concave indentation of the waist, while the support points and thus the supporting forces acting on the guitar from this area are deliberately laid out in more stable areas of the guitar sound body.
  • An S-shaped curved shape according to the present invention is understood to mean a non-straight, at least double-bent shape resulting from the curved shape of the side wall of the guitar sounding body.
  • the support base member is at least provided with a slightly convex and with a slightly concave curvature to adapt to the corresponding radii of curvature in the waist region and the lower bulges.
  • two slightly convex curves may be provided with an intermediate concave curvature. It goes without saying that, depending on the shape and size of the guitar, correspondingly slightly different curved shapes of the support base member can be realized.
  • the voltage applied to the frame of the guitar element is not straight, but follows the curved S-shape of the frame of the guitar.
  • the collapsible or stowable design of the positioning and the leg rest can be achieved, for example, that the positioning element in the form of the support base member corresponds and can be folded over the hinge on this.
  • Other forms of implementation for folding or stowing the elements essentially in the plane of the support base element are also conceivable, as long as they protrude as little as possible from the curved S-shape plane of the support base element when not in use.
  • the legrest according to the invention is structurally very easy to implement. Few items are required for their manufacture, yet provide overall very stable and effective support in an ergonomically optimal manner for the instrument player.
  • the support base element of the leg support extends approximately over the entire waist region of the guitar, i. the concave, inwardly arched middle section of the orchestra.
  • the support base member extends from a region of an upper convex bulge of the chime of the guitar sound body to a portion of a lower convex protrusion.
  • the support base member is preferably apart from end attachment points of the sounding body, i. the frame spaced so that no contact takes place in the sensitive middle waist region. Since the support base member extends substantially over the entire central waist region, relatively wide spaced mounting portions of the leg support are possible, which can also be provided in less sensitive areas of the guitar sound body.
  • the construction is reinforced by stiffening elements in the usual guitar designs in the area of the respective upper and lower bulge in the interior, so that pressure forces exerted here can be taken without problems and also have a much lower impact on the acoustics than when pressurized in the mid-waist area Attachment points would be.
  • the relatively wide extension of the support base element over the frame of the guitar offers a wide spread and therefore safe and stable support of the entire guitar.
  • the support of the guitar by the legrest is therefore not punctiform, but at two laterally spaced areas, so that the center of gravity of the guitar is between the respective support areas of the legrest.
  • the leg rest with the support surface for abutment with the thigh is a flexible belt which on the one hand and on the mounting element on the other hand is attached.
  • a flexible belt for example, a textile belt, a leather strap or a plastic band may be provided, wherein the advantage of a flexible embodiment of the leg support surface is to be seen in that the leg rest adapts flexibly to the shape of the thigh of the user.
  • the legrest is thus acoustically decoupled from the body of the instrument player.
  • the flexible belt is easily inserted in the plane of the support base member or stowed by the excess strap portions are simply folded together.
  • a flexible belt has the advantage that the desired spread position of the legrest, ie the installation angle ⁇ between the support base member and the erection element, is assured in a structurally very simple manner.
  • the belt is a tensile load-bearing element, which is designed according to an advantageous embodiment as a non-stretchable textile belt.
  • the legrest is thus very compact in the folded state and can be completely folded in particular for transport according to the sidewall region of the guitar and be transported in the guitar case without removing the guitar.
  • the legrest can also be adjusted in a very easy way. A complex disassembly or setting operations by means of locking screws or the like are not required here.
  • a particularly advantageous material for the belt serving as a leg rest is a velvet band, which is mounted on the side facing the leg with the slippage-preventing velvet lining, whereas the smooth back lies on the side facing away from the leg.
  • a velvet ribbon has the further advantage that a once set in length belt can not adjust so easily, since slipping in the attachment end is largely avoided by the material.
  • the belt is fixed in a length-adjustable manner on the support base element and / or on the positioning element.
  • the belt only needs to be loosened at its fixation and adjusted to the desired length.
  • a means for length adjustment of the belt may serve any means known to those skilled in the art. Conceivable, for example, a releasable via a hook and loop fastener of the webbing, mounting projections and corresponding holes in the belt, a clamping fixation of the belt, etc.
  • the length-adjustable fixation of the belt is realized as a buckle-shaped multiple deflection by a plurality of transverse slots in the support base member through which the belt is respectively performed and deflected.
  • This type of fixation of the belt is on the one hand very easy to use and on the other hand very easily realized without additional components. Due to the multiple deflection in the slots in the base member and possibly switching on additional clamping or fixing the belt is securely fixed and yet can be varied in length without cumbersome manipulations of adjusting screws, sliding slides or the like.
  • the fixation by means of belt-shaped multiple deflection of the belt can be secured according to an advantageous aspect of the invention via an additional clamping element which can be used between the belt and the support base member for fixing the belt.
  • an additional clamping element which can be used between the belt and the support base member for fixing the belt.
  • Such a plate-shaped clamping element lies flat with tensioned belt to the surface of the support base member, wherein the belt passes over the clamping element and this holds. Because of this wedge or clamping effect, a very high load on train fixation is provided, which is, however, by soliciting or raising the clamping element again solvable.
  • the set-up element which protrudes in the position of use substantially perpendicularly from the support base member, according to the support base member is shaped such that it is almost completely in the retracted position in the plane of the support base member.
  • the legrest is in the folded position, ie when not in use, eg during transport, maximally reduced in height and is essentially only a few millimeters thick, depending on the thickness of the material selected for the support base element and the positioning element.
  • the positioning element rests against the supporting base element in the folded-in position, so that it also contributes only insignificantly to the overall height of the support in the folded-in state.
  • the corresponding shape of the positioning element is also a curved shape, which corresponds to the radius of curvature and in the buckling direction.
  • the on adjusting element has smaller dimensions than the support base member so as to be received in the folded position completely in a formmeratien, provided centrally in the support base member recess.
  • the legrest is designed very thin in the folded transport position and, for example, only a few millimeters in height. Therefore, the guitar player can leave the leg rest on the guitar body even when the guitar is being carried, as it fits snugly and flat against the sidewall of the guitar and can remain between the sidewall of a guitar case and the guitar itself in the already given gap.
  • the manufacture of the leg support is facilitated in this way by a proper "cutting out" of the positioning element from a central region of the support base element.
  • the legrest is realized, for example, from a metal sheet, the erection can therefore be simply cut or punched in the middle of the plate, without additional material would be required for this.
  • the support base member on the side facing the guitar a plurality of spacer blocks, so that the support base member rests directly on the frame of the guitar only at the level of the spacer pads. It is thus provided a kind of spacer, so that the legrest is supported directly only at specific locations on the frame and otherwise the side wall is not loaded and not impaired in its acoustic behavior.
  • the spacer blocks also ensure that the sidewall of the guitar is loaded only at selected areas and, moreover, that the forces transmitted from the support base member to the guitar are essentially only orthogonal compressive forces without transverse stress. The stability of the support of the legrest and the secure support of her are thereby ensured.
  • detachable fastening means for fastening the legrest are provided on the support surface of the support base element pointing towards the guitar. This allows the legrest to be easily removed and re-attached as needed.
  • the instrument player can play the instrument either with or without leg rest, since it is not a permanent, but a releasable fixation in the attachment.
  • releasable fastening means Velcro closures, adhesive joints or other adhesive fasteners may be mentioned.
  • suction cups are not considered to be particularly preferred in the context of the present invention because they are more in the center region of the frame and therefore to be arranged in the pressure sensitive region of the guitar sound body due to the relatively large required suction surface, especially velcro-like fasteners are preferred.
  • the latter can be positioned very far in the edge region and in particular also in the corner edges between the frame and the bottom and the lid of the guitar.
  • Essential to the invention is that the releasable fixation is done in a way that the guitar sound body does not need to be pierced or otherwise damaged. Especially with high-quality concert guitars, such a legrest would not be usable.
  • an adhesive bond fixed on the lacquer of the surface is easily removable again without damaging the instrument, in particular the instrument surface.
  • a hook and loop fastener as a fastening means between the support base member and the side wall of the guitar is preferably one of the Velcro elements mounted on the frame via a self-adhesive at appropriately selected positions, whereas the mutual Velcro element is preferably mounted in the corner regions of the spacer blocks.
  • a fastener of the Velcro fastener type has the advantage that it remains functional over the long term and, in particular with the present compressive stress, a sufficiently secure and very flat fixation is ensured in a structurally very simple manner essentially without lateral shear or shear forces.
  • four spacer blocks and four respectively attached thereto fastening means are provided, which are arranged at the outer corners of the substantially rectangular support base member.
  • the displacement or arrangement of the attachment points at the outer corners has the advantage that the support and thus the compressive stress on the part of the legrest on the guitar sound body takes place in places that are anyway formed as reinforced areas due to the constructive internal structure of the guitar sounding body.
  • reinforcing tires are also provided on the inside for connection between the frame and the bottom or cover element, so that here greater pressure forces can be absorbed without the guitar is at risk of being damaged.
  • the spacer pads and fasteners can be placed in relatively widely spaced areas, i.
  • These areas are therefore also less sensitive in acoustic terms, so that the attachment and the support of the legrest here have no significant impact on the sound of the instrument.
  • the leg rest ie the resting on the thigh of the user support surface, mounted and aligned at an angle with respect to the support base member so that the support surface is angled in the use position of the leg support.
  • An angling here means a slightly oblique orientation of the leg rest, so that a slight angle results between the plane of the support base element and the plane serving as a support surface.
  • the angling of the leg rest with respect to the leg rest has the advantage that the guitar naturally inclines slightly obliquely upwards towards the user in relation to the vertical, ie that the upper side of the guitar body is closer to the upper body of the instrument player than the underside of the guitar. This is ergonomically better for playing the instrument.
  • the angle ⁇ between the leg rest and the support base member is preferably about 5 to 15 degrees, so that an optimal, to the user slightly inclined support of the guitar is achieved. An optimum angle of attack ⁇ was found at 10 degrees.
  • the slight bending of the legrest takes into account the fact that in normal sitting positions and at normal seat height, the thighs of the user are usually slightly sloping forward, ie inclined aligned. Due to the slight angular position of the leg rest this fact is taken into account in a very simple manner.
  • the bending of the leg rest with respect to the support base element can be effected, for example, by fixing the leg rest or the strap forming the leg rest on one side at an angle to the longitudinal direction and transverse direction of the support base element.
  • the belt can also be slightly obliquely attached on both sides, ie on the side of the erection element as well as on the sides of the support base member.
  • four attachment points between the guitar and the leg support are provided in respective corner regions of the support base member, wherein the four attachment points of the support base member on the frame of the guitar are arranged substantially in the same position as inner reinforcing struts and / or reinforcing tires of the guitar , A support and thus a compressive stress of the guitar sound body is thereby only amplified in accordance with the inside of the guitar Positions. The sound quality of the instrument is largely retained. Damage caused by excessive pressure on the guitar in sensitive areas such as the only a few millimeters thick frame at unprotected middle areas is thus avoided.
  • the positioning element is provided with a hinge, via which the positioning element is at least partially pivoted in relation to the support base element transversely to the longitudinal direction.
  • a kind of double joint is provided with an additional degree of freedom in the possibility of movement of the positioning element.
  • the leg rest is formed as a rigid, slightly curved element and is articulated relative to the support base member.
  • the linkage can be realized in the form of a hinge or any other form of joint.
  • the slightly curved shape ensures that the leg rest in the folded position substantially on the (also according to the guitar side wall) bent supporting base element and the entire support then occupies a very small space. The support can therefore be stored together with the instrument in a box.
  • a plurality of opening slots is provided in the positioning, in which the rigid leg rest height adjustable via corresponding holding means is fixed.
  • the plurality of openings allows a stepwise adjustment of the installation angle ⁇ , so that the guitar inclination (inclination angle ⁇ ) can be adjusted in the simplest way by the instrument player as desired.

  • FIG. 5 which shows a view corresponding to FIG. 4, on the side of the hinge 19 the positioning element 5 is articulated in a bevel at an angle ⁇ , as can be seen by the drawn axis of rotation A of the hinge 19 is, whereas the transverse slots 13, 21 for the belt (not shown) straight, ie aligned along the transverse axis.
  • the two embodiments of FIGS. 4 and 5 do not differ. It is also a combination of the two variants of Figs. 4 and 5 conceivable, ie that both the articulation axis or axis of rotation A at the hinge 19 of the positioning element 5 and the transverse slots 13, 21 are aligned obliquely in the angle ⁇ .
  • FIG. 6 shows, in a schematic perspective view, a detail of the area and the adjustment possibility of the belt 6 via a multiple deflection 7 and a clamping element 14.
  • 7a and 7b are respective detail views in a top view and a side view of the clamping element 14, which is used in the embodiment of FIG. 6 for the length-adjustable fixation of the belt 6.
  • the length adjustment of the belt 6 serving as a leg rest 2 can be performed in this exemplary embodiment with a multiple deflection 7 of the belt 6 in a conceivably simple and intuitive manner.
  • the user merely has to lift the clamping element 14 out of the position lying flat against the supporting base element 3 (cf., Fig. 1), as shown in Fig.
  • the clamping member 14 is a flat plate with corners corners slightly bent up at the corners to facilitate gripping by the user becomes.
  • the clamping member 14 is formed with a bent portion, a Einhakkante 17, which can be inserted into the corresponding slot 13 in the support base member.
  • a kind of fixed joint fixation of the clamping member 14 is provided with respect to the support base member 3, which prevents loss of the clamping member 14.
  • the Einhakkante 17 increases in the folded state of the clamping element 14, ie in the clamping position, the clamping action on the passing between the clamping element 14 and the slot 13 webbing 6. As a result, the effect of the clamping fixation in this multiple deflection 7 is still enhanced.
  • adjustable length fixation of the belt 6 is conceivable, and for example, a simple deflection can be provided in combination with a hook and loop fastener at the top of the support base member 3. Combinations of hooks on the support base element 4 and rows of holes in the belt 6 may also be provided, which allow different positions in certain stages in the fixing of the belt 6 to the support base element 3.
  • the shortening of the belt 6 and thus the inclination angle ⁇ of the guitar neck 15 can also be done by simply pulling the velvet belt or belt 6 (see also indicated with the arrow C in Fig. 2 adjustment direction of the belt 6) without actuation of the clamping member 14th
  • Fig. 8a is a perspective view of a third embodiment of a legrest according to the invention in the unfolded position ready for use, in which the positioning element is provided with a pivot bearing.
  • the positioning element 5 is no longer one piece and substantially rigid, but it is divided approximately in the middle in an upper portion and a separate lower portion.
  • the two sections of the positioning element 5 are connected to each other by a hinge 22.
  • the joint 22 has an axis of rotation in alignment parallel to the longitudinal direction of the positioning element 5.
  • the positioning element 5 thus has an additional alignment possibility, thanks to the joint 22.
  • the rotary joint 22 is a simple rod which is mounted in bores of slightly protruding mounting shoes on both sides of the sections of the erection element.
  • Other types of hinges for the joint 22 are also conceivable as long as a twisting possibility about a longitudinal axis is provided.
  • this embodiment substantially corresponds to the previous embodiments of FIG. 1 to 6.
  • Fig. 8b shows in a schematic perspective view of the guitar leg rest of the embodiment of FIG. 8a, but here in the folded state for the purposes of stowage and transport.
  • FIGS. 9a and 9b respectively show schematic perspective views - FIG. 9a in the use position, FIG. 9b in the stowage position - of a fourth embodiment of the leg rest for guitar players according to the invention.
  • the leg rest 2 is designed as a rigid element 29 and no more than a flexible band.
  • the leg rest 2 here is a plate-shaped, slightly curved element 29, which is articulated on a part of the support base element 3.
  • the support base member 3 is divided into two sections, a positioning member holding portion 25 and a leg rest holding portion 26. At the latter, the leg rest 29 constituting the leg rest is fixed via a double joint 24.
  • the leg element 29 can be rotated so that the curvature in the stowed position adapts to the curved shape of the support base element 3 and the space required is minimal.
  • a double joint 24 is meant in the present context, each joint which allows a rotation in two different directions.
  • the person skilled in the art knows various types of such double joints.
  • the example shown in FIGS. 9a and 9b of a double joint 24 consists of a central pin which is rotatably mounted in a bore in a joint rod. The latter is in turn mounted even in bearing or mounting shoes 28 to allow the pivoting of the leg member 29.
  • the positioning element 5, however, is hinged here with a simple hinge hinge on the support plate 27. However, this is not limitative of the invention and the support base member 3 could also be integrally divided into two parts.
  • the rigid, curved leg element 29 is inserted at the free end in a receiving slot 31 provided on the positioning element 5 via a pin as holding means 23 and is clipped or clamped in this example.
  • the plurality of slots 31 on the deployment member 5 allow the adjustment of the desired height of the instrument, i. a change in the angle of the legrest.
  • the leg member 29 of the leg rest 2 on the convex side is provided with an anti-slip material 30, which may be applied as a coating or coating, for example.
  • the invention is by no means limited to the illustrated embodiments and includes every technically feasible equivalent, as long as the scope of the following claims is not abandoned.
  • a wide variety of materials for the elements of the legrest 10 can be used.
  • One possible material for the realization of the support base element 3, the set-up element 5 and the clamping element 14 is aluminum or an aluminum alloy, for example an AlZnMgCu alloy.
  • Plastic materials are also conceivable as well as the use of advantageous in aesthetic terms wood materials, such as plywood with veneers and colors formed according to the guitar.
  • a plastic material molded plastic can be used by injection molding or fiber reinforced plastics, such as GRP.
