  • the pivotal connection includes a releasable locking device that selectively locks the pivotal connection as well as the relative pivoting movement of the clamping arm and the string contact arm against movement in an opening direction while allowing relative pivoting movements in a closing direction.
  • a capo which has a rigid arm which is intended to extend across the neck over strings of a stringed musical instrument.
  • a string contact part is arranged on this arm.
  • a resiliently formed C-shaped part is connected to the arm. About this part can exert a clamping force.

  • the opening direction of the at least one slot or the at least one groove is oriented at least approximately parallel to the strings, when the capo is clamped to the neck, wherein the opening direction at least approximately parallel to the first Contact surface and at least approximately parallel to the second contact surface is oriented and that by contact of the at least one first contact surface and the at least one second contact surface is a Austrop-displaceability of the first arm to the second arm, which increases the distance between the string conditioning area and the neck rear side abutment area, lockable.
  • the capo tasto according to the invention can be produced in a simple manner with a minimization of the number of required components.
  • the contact surfaces can be formed so that they are only effective when a pressure force is exerted on the arms through the neck, d. H. if a fixation or pre-fixing has been done on the neck of the stringed musical instrument. It can thereby perform a clamping pressure metering. Too great a tension on a string can cause a detuning of the string. A too low clamping pressure can cause a whirring of the string. In the solution according to the invention an optimized setting is possible.
  • the sliding bearing has a displacement guide, which is arranged on the second arm.
  • a displacement guide can be formed in a simple manner.
  • the displacement guide is formed by at least one slot or at least one groove on an arm (such as the second arm). In this at least one slot or in the at least one groove can be the other arm (for example, the first arm) or a fixed to the other arm element lead.

This allows easy one-hand operation. The number of required components is minimized. In addition, an adjustment of the pressure force in a simple manner possible, since a Friedippo-displaceability is possible.
  • the opening direction is a direction transverse to the direction of displacement. It points in the outer space and is a dipping direction, over which (at least) one pin element of the other arm is immersed in the at least one slot or the groove.
  • the opening direction is at least approximately parallel to the strings. It is also oriented transversely to a side surface of the corresponding arm.
  • the opening direction is that direction, to which the at least one slot or the at least one groove is not limited at least on one side by material of that arm on which the at least one slot or the at least one groove is formed.
  • the at least approximately parallelism of the opening direction to the first contact surface and the second contact surface is present at each contact position of the first contact surface and the second contact surface before and in particular in each position of the first arm to the second arm.
  • the first arm or the second arm may each be formed in one or more parts.
  • the at least one first contact surface and the at least one second contact surface are formed such that the contact-apart mobility is blocked when the capo is clamped on the neck. It then acts a compressive force, which blocks the movement apart of the first arm on the second arm. However, an operator can still move the first arm on the second arm, if the clamping force is to be increased.
  • At least one first contact surface and the at least one second contact surface are designed such that a Auffactzu-displaceability of the first arm and the second arm in the opposite direction to a disengaging direction of the first arm and the second arm is released. This allows you to adjust the clamping force.
  • the displacement guide is a linear guide. It is sufficient if the first arm on the second arm is linearly displaceable.
  • the at least one second contact surface is at least approximately parallel to the displacement guide.
  • the first arm is held on at least one pin element on the displacement guide. Via the at least one pin element, which is immersed in the displacement guide, a mobility of the first arm on the second arm can be realized in a simple manner.
  • the at least one pin element may be a separate from the first arm and fixed to this element. It can also be formed in one piece on the arm. It may for example also be designed as a pin.
  • a longitudinal extension direction of the at least one pin element is parallel to the opening direction of the at least one slot or the at least one groove. This longitudinal extension direction is then parallel to the first contact surface and the second contact surface.
  • the sliding bearing is designed as a pivot sliding bearing, wherein the first arm is pivotable relative to the second arm. This can facilitate the placement and release of the capo on the neck of the stringed musical instrument. By a pivoting apart of the first arm and the second arm can be easier to put on the neck, in particular a one-handed placement is facilitated. Furthermore, the release can be easier.
  • a pivot axis of the pivot sliding bearing is perpendicular to the displacement direction.
  • the pivot sliding bearing can be formed in a simple manner.
  • a pin element, which serves for the displacement guidance of the first arm on the second arm, can also serve as a shaft for the pivotal mounting.
  • the pivot axis is preferably parallel to the opening direction and thereby also parallel to the first contact surface and the second contact surface.
  • the pivot sliding bearing has a shaft which is guided displaceably in a displacement guide and in the displacement guide is rotatable.
  • the corresponding capo can thus be produced with minimal effort.
  • the displacement guide is oriented at least approximately perpendicular to the strings when placed on the neck capo. This allows a uniform pressure distribution on the strings realize; By a linear and at least approximately vertical mobility of the first arm with the string conditioning area on the string during clamping, it can be achieved that all strings are at least approximately uniformly pressurized.
  • a pivotable rocker is arranged on the first arm, on which the string conditioning area is seated.
  • the pivot bearing is arranged in particular centrally on the rocker.
  • the swiveling rocker distributes the clamping pressure of the string conditioning area evenly over the strings. This prevents the distribution of pressure on the strings from being different, which may cause some strings to be out of tune and other strings to be buzzing due to low pressure. As a result, the operator is also a larger pressure range or range available before strings are audibly detuned.
  • an inventive capo is universally applicable by providing a pivotable rocker; it is no longer necessary to adapt individual span widths to individual instruments. The uniform clamping pressure distribution allows use with different bundle lengths.
  • capo scavengers known from the prior art, the fundamental problem arises that fixation takes place immediately upon contact and, as a result, optimal alignment of a string conditioning area is no longer possible.

  • a pivot axis of the rocker is parallel to a pivot axis of a pivot sliding bearing, via which the first arm is held on the second arm.
  • the string conditioning area is formed by means of an elastic material. This allows a simple way to achieve a uniform force distribution.
  • the string conditioning area is formed by an elastic pad. This is for example in one piece. As a result, a uniform pressure distribution on the strings can be achieved even with a curved neck of a stringed musical instrument.
  • the elastic pad has a varying contact surface for strings transverse to a string extension direction, wherein the effective contact surface for strings with a larger diameter is smaller than for strings with a smaller diameter.
  • the effective contact surface with which a string rests against the elastic pad, results from the diameter of the string times the contact length of the string with the elastic pad. For strings with a larger diameter would result in the same contact length on the elastic pad a larger effective contact surface. This could cause the string to penetrate less deeply into the cushion.
  • the effective contact surface for the strings which ensures that the contact length of strings of different diameters for the system on the contact surface is different, it is ensured that the effective contact surface of different strings is at least approximately equal. This prevents, for example, thicker strings (bass strings) penetrating less deeply into the elastic pad than thinner strings. This in turn will the Danger reduces that thicker strings can dodge while playing the stringed musical instrument.
  • the elastic padding on a triangular space can provide a varying string contact surface, which increases in one direction. This direction is transverse to the string extension directions. This can provide at least approximately equal effective string conditioning surfaces for thicker strings and thinner strings.
  • the contact area for the back of the neck is formed by an elastic pad. This avoids damage by applying the second arm to the back of the neck. Furthermore, a fixation of the capo tasto on the neck is possible in a simple manner. By applying pressure to the elastic pad this is compressed and thereby, when a corresponding displacement position of the first arm is present to the second arm, achieve a blocking position by contact of the at least one first contact surface and at least one second contact surface. The blocking position can in turn be canceled in a simple manner, if a further force is exerted on the elastic pad to allow relative pivoting between the first arm and the second arm.
  • the first arm has a channel-shaped area with raised side edges, on which the string conditioning area is arranged.
  • the string conditioning area can be easily fixed to the first arm and, in particular, pivotally fixed.

H. with respect to one end of the string conditioning region, which is closest to the second arm, the string conditioning region has a greater length than the first arm. It has been shown that this is a uniform clamping pressure on the strings exercisable.
