Description

DRUM FEET

The invention relates to a drum pedal for playing a drum, comprising a beater that can be actuated via a pedal. For actuation, a deflection device acts between the pedal and the beater, by means of which the beater can be deflected from a rest position and returned to the rest position. The deflection device is carried by a swivel arm which is connected to a base plate.

The drum pedal is designed to play a bass drum on the drums with your foot. In particular, the percussion pedal is set up to deflect the mallet orthogonally to a head of the bass drum, with the mallet hitting the head of the drum.

In conventional drum pedals, the swivel arm and its attachment to the base plate are rigid in order to ensure the highest possible mechanical stability of the drum pedal. The rigid connection between the swivel arm and the base plate means that the drum pedal takes up more space, which has a particularly disadvantageous effect when transporting the drum pedal.

German patent specification 19 10 205, US patent specification 5 365 824 and British patent specification 747 804 describe drum pedals which can be changed in a condition intended for transport.

The present invention is based on the object of designing and developing a drum pedal for playing a drum of the type mentioned above, so that it can be brought from an operating state to a transport state in a particularly simple manner, with the drum pedal being in the transport state has a particularly small pack size.

According to the invention, the above object is achieved by the features of claim 1. After that, the swivel arm can be locked by means of a Pivot axis pivotable relative to the base plate, a transport state and a loading operating state being adjustable by pivoting the pivot arm about the pivot axis. In the transport state, the swivel arm rests against the base plate and in the operating state, the swivel arm is set up relative to the base plate.

According to the invention, it has been recognized that the combination of the swivel arm with a lockable swivel axis makes it particularly easy to switch between the transport state and the operating state of the drum pedal. Furthermore, the mentioned combination enables a particularly small pack size of the drum pedal when being transported. The swivel arm rests against the base plate in the transport state. Here and in the following, abutting means that a direction of extension of the flap of the swivel arm and a plane of extension of the flap of the base plate essentially run parallel to one another. For example, an angle between the flap direction of extension of the swivel arm and the flap extension plane of the base plate is at most 45°, preferably at most 20°, particularly preferably at most 10°. In the operating state, the swivel arm is set up relative to the base plate. Here and in the following, erected means that the Flaupter direction of extension of the swivel arm runs transversely, in particular orthogonally, to the Flaupter plane of extension of the base plate. For example, an angle between the flap direction of extension of the pivot arm and the flap extension plane of the base plate is between 50° and 90°, preferably between 70° and 90°, particularly preferably between 85° and 90°.

According to one embodiment of the drum pedal, the pedal and the deflection device are detachably connected to one another in the operating state and the connection between the pedal and the deflection device is released in the transport state. For example, the pedal is hooked onto the deflection device in the operating state, so that there is a positive connection between the pedal and the deflection device. Furthermore, the pedal can be detachably connected to the deflection device by means of a screw connection. In the transport state, the connection between the pedal and the deflection device is released, so that the deflection device cannot be actuated by means of the pedal. Advantageously, the detachable connection between the pedal and the deflection device enables the drum pedal to be packed to a particularly small size in the transport state.

According to one embodiment, the pedal can be inserted between the swivel arm and the base plate in the transport state, with the deflection device applying a compressive force to the inserted pedal via the beater and pressing the pedal against the base plate. In particular, the swivel arm can be locked in the transport state by means of the lockable swivel axis, so that the main extension direction of the swivel arm has a fixed angle relative to the main extension plane of the base plate. In particular, the swivel arm is not moved relative to the base plate by the pressure force applied to the pedal by the deflection device. For example, there is

Transport state due to the compressive force, a non-positive connection between the inserted pedal, the base plate and the mallet. In the transport state, the pedal is advantageously fixed to the base plate by means of the mallet.

According to one embodiment, the pivot axis is locked in the operating state. When the swivel axis is locked, the relative position of the

Swivel arm fixed to the base plate. For example, the

Pivot axis an eccentric by means of which the pivot arm can be clamped in a predetermined position. In particular, the angle between the

The main extension direction of the swivel arm and the main extension plane of the base plate can be continuously adjusted and locked. In particular, the eccentric includes a quick release, which can be closed and opened by hand without the use of tools. Advantageously, the locked pivot axis offers a particularly stable mount for the deflection device, so that particularly reliable operation is made possible.

According to one embodiment, the rest position can be adjusted by means of the deflection device. For example, the deflection device includes an adjusting screw, by means of which the angle between the swivel arm and the beater can be adjusted in the rest position. For example, this is in the operating state of the Adjustable beater travel from rest position to beater impact on eardrum.

According to one embodiment, the deflection device returns the beater to the rest position with a restoring force, the restoring force being adjustable by means of the deflecting device. For example, the deflection device includes an elastic element, in particular a spring, which pulls the beater into the rest position. In particular, when the pedal is actuated to deflect the mallet, the restoring force must be overcome in order to move the mallet out of the rest position. When adjusting the restoring force, the preload of the elastic element is changed. Advantageously, the force required to operate the drum pedal can thus be adapted to individual playing habits.

According to one embodiment, a mechanical stop in the rest position specifies the position of the pedal, with the pedal being in contact with the mechanical stop via a damping element. The damping element is formed, for example, with an elastically deformable material, in particular rubber. The damping element can be arranged between an element forming the mechanical stop and the pedal, so that the pedal and the mechanical stop are in indirect contact with one another via the damping element. Advantageously, the damping element reduces noise that occurs during operation.

According to one embodiment, the base plate has a guide element, the guide element acting as a linear guide along the main extension plane of the base plate. The guide element comprises, for example, two guide rails which run parallel to one another. Both in the operating state and in the transport state, the two guide rails directly adjoin two opposite sides of the pedal, as a result of which a movement of the pedal is guided parallel to the main plane of extension of the base plate. According to one embodiment, the guide element guides movement of the pedal along a longitudinal direction, the longitudinal direction extending from the guide element in the direction of the pivot arm. In particular, the pedal is connected to the deflection device and the guide element in the operating state in such a way that the pedal can perform a linear translational movement parallel to the main plane of extension of the base plate.

According to one embodiment, the drum pedal comprises an anchoring element, which is provided for anchoring the drum pedal to the drum. The anchoring element is set up, for example, to be attached to a rim of the drum. The anchoring element can form a non-positive and/or positive connection between the drum and the drum pedal. Advantageously, the drum pedal and the drum are fixed relative to one another, so that when the pedal is actuated, a constant position of the base plate relative to the drum is ensured.

According to one embodiment, the drum pedal includes a number of pedals, each of which is set up to actuate the deflection device. In particular, pedals can be coupled to the deflection device by means of a cardan shaft, so that when any pedal is actuated, the beater can be deflected from the rest position.

According to one embodiment, the drum pedal includes a plurality of drumsticks, each of which can be actuated by means of the deflection device. In particular, the beaters can be actuated separately from one another by means of different pedals of the plurality of pedals.

According to one embodiment, the deflection device comprises a shaft, a pulling device and a restoring device, with the beater being pivotably mounted on the shaft. The pedal can be mechanically coupled to the shaft by means of the pulling device, so that when the pedal is actuated, the shaft is moved in a first direction of rotation. The restoring device exerts the restoring force on the shaft, the shaft rotating in a second direction by means of the restoring force is moved. The first direction of rotation and the second direction of rotation are opposite to each other. The pulling device includes, for example, a chain, a belt or a metal joint via which a pulling force is transmitted from the pedal to the shaft. This tensile force acts, for example, tangentially to the first direction of rotation.

The restoring device comprises, for example, a spring whose restoring force acts at least partially tangentially on the shaft in the second direction of rotation.

Fig. 1 shows a schematic side view of an embodiment of a percussion pedal 1 in operation. The drum pedal 1 to summarizes a pedal 2 by means of which a beater 3 can be actuated. For actuation, a deflection device 5 acts between the pedal 2 and the beater 3, by means of which the beater 3 can be deflected from a rest position and returned to the rest position. The deflection device 5 is carried by a pivot arm 6, the pivot arm 6 being pivotable relative to a base plate 8 by means of a lockable pivot axis 7. A transport state and the operating state can be set by pivoting the pivot arm 6 about the pivot axis 7 . In the transport state, the swivel arm 6 is in contact with the base plate and in the operating state, the swivel arm 6 is set up relative to the base plate 8 . The base plate 8 has a flap extension plane 13 and the pivot axis 6 has a flap extension direction 14 . In the operating state, the flapper extension direction 14 runs essentially orthogonally to the flapper extension plane 13. In particular, an angle between the flapper extension plane 13 and the flapper extension direction 14 is greater than 45°, preferably greater than 70°.

On the base plate 8, a guide element 12 is arranged, which acts as a linear guide for the pedal 2 along the Flaupter extension plane 13 of the base plate. The guide element 12 leads a movement of the pedal 2 along a Longitudinal direction 20, which runs from the guide element 12 in the direction of the swivel arm 6.

The drum pedal 1 comprises an anchoring element 15, which is provided for anchoring the drum pedal 1 to a drum, not shown here.

2 shows a schematic side view of the embodiment of the drum pedal 1, in which the connection between the pedal 2 and the deflection device 5 is released. The pedal 2 is placed on the base plate 8. The guide element 12 specifies the position of the pedal 2 perpendicular to the longitudinal direction along the main extension plane 13 of the base plate 8 . The quick release 9 is open so that the pivot axis 7 is not locked. The swivel arm 6 can thus be swiveled about the swivel axis 7 relative to the base plate 8 .

3 shows a schematic side view of the embodiment of the drum pedal 1, which is in the transport state. The swivel arm 6 is applied to the base plate 8 so that an angle between the direction of main extension 14 of the swivel arm 6 and the main plane of extension 13 of the base plate 8 is less than 45°. The pedal 2 is inserted between the swivel arm 6 and the base plate 8 , with the deflection device 5 pressing the beater 3 onto the pedal 2 . The pedal 2 is thus pressed against the base plate 8 . As a result, the pedal 2 is held on the base plate 8 by means of a force fit.

4 shows a schematic perspective view of a front view of the anchoring element 15 and the pivot axis 7 of the drum pedal 1. The anchoring element 15 includes a clamping jaw 16 which is arranged between two clamping pads 17 . To fix the anchoring element on a drum, the clamping jaw 16 is pulled in the direction of the base plate 8 by means of a screw. The clamping jaw and the clamping pads thus engage on opposite sides of a drum edge and form a non-positive and/or positive connection between Drum and drum pedal 1. The clamping jaw 16 and the clamping pad 17 are formed with an elastic material, such as plastic, in order to prevent the anchoring element 15 from damaging the drum

5 shows a schematic side view of the base plate 8, the anchoring element 15 and the quick release 9 of the drum pedal 1. If the quick release 9 is applied to the base plate 8, the pivot axis 7 is locked and the pivot axis 6 is rigid with it the base plate 8 connected. If the quick release 9 is raised from the base plate 8 , represented here by dashed lines, the pivot axis 7 is not locked and the pivot arm 6 can be rotated about the pivot axis 7 .

6 shows a schematic perspective view of the base plate 8, the guide element 12 and the pedal 2 of the drum pedal 1. The pedal 2 and the base plate 8 are only partially shown. The guide element 12 comprises two guide rails 21 which bear against two opposite sides of the pedal 2 along a transverse direction 19 . The transverse direction 19 runs along the Flaupter extension plane 13 of the base plate 8 perpendicular to the longitudinal direction 20. The pedal 2 is thus guided along the longitudinal direction 20 by means of the guide element 12. When the pedal 2 is actuated, a sliding movement of the pedal 2 within the guide element 12 along the longitudinal direction 20 is possible.

Fig. 7 shows a schematic plan view of a section of the base plate 8 and the guide element 12 of the drum pedal 1. The guide element 12 has a base plate 22 in which a recess 23 is formed. The recess 23 extends along the longitudinal direction 20. The pedal 2 has a guide pin 24 on its underside, which can be inserted into the recess 23, so that the pedal 2 rests on the guide element 12 in a predetermined manner and with particularly low friction along the Longitudinally 20 can slide in the guide element 12. The guide pin 24 of the pedal 2 is shown in FIG. Fig. 8 shows a schematic perspective view of the base plate 8 with the guide element 12, the support rail 18 and the pivot axis 7 of the drum pedal 1. The base plate 8 is between the guide element 12 and the support rail 18, to which the pivot axis 7 is attached is, continuously formed. In particular, the base plate 8 is intended to rest on the floor with a side facing away from the guide element 12 and the support rail 18 .

FIG. 9 shows the deflection device 5 of the drum pedal 1 in a schematic side view. The shaft 25 can be rotated about an axis of rotation 26 . A resetting device 27 and a pulling device 28 engage on the shaft 25 . On the shaft 25 of the beater 3 is pivotally mounted. The pedal 2 can be coupled mechanically to the shaft 25 by means of the pulling device 28 so that when the pedal 2 is actuated the shaft 25 is moved in a first direction of rotation 29 . The restoring device 27 exerts a restoring force on the shaft 25, the shaft 25 being moved in a second direction of rotation 30 by means of the restoring force. The first direction of rotation 29 and the second direction of rotation 30 are opposite to one another.

The pulling device 28 includes an adjusting screw 31 by means of which the length of the pulling device 28 can be changed, so that the rest position of the deflection device can be adjusted by means of this adjusting screw 31 . The return device 27 is formed by an elastic spring which is fixed to a fixing axis 32 . The fixing axis serves as a counter bearing for the restoring device 27 so that it can exert the restoring force on the shaft 25 . Furthermore, the fixing axis 32 forms a mechanical stop 10 against which the pedal 2 rests in the rest position. The damping element 11 is formed on the pedal 2, via which the pedal and the mechanical stop 10, in this case the fixing axis 32, are in contact with one another.

The resetting device 27 is intended to reset the mallet 3 with a resetting force into the rest position. The fixing axis 32 can be displaced along the main extension direction 14 of the swivel arm 6 . by means of push the fixing axis 32, the bias of the return device 27 is adjustable. For example, the fixing axis can be displaced along the direction of flap extension 14 by means of a screw thread.

10 shows the pedal 2 of the percussion foot machine 1 in a schematic top view. The pedal comprises a front area 33, a middle area 34 and a rear area 35. The rear area 35 is intended to be inserted into the guide element 12 to be inserted, so that the guide rails 21 lead to a movement of the pedal 2 along the longitudinal direction 20 when the pedal 2 is actuated. The middle area 34 is made wider along the transverse direction 19 than the rear area 35, so that when you place your foot on the pedal 2, the middle area 34 offers enough space for the balls of your feet. The rear area 35 is intended to ensure that when the pedal 2 is actuated, the heel rests on it. The guide pin 24 is formed on a rear side of the pedal 2 in the rear area 35, which is not illustrated here.

The front area of the pedal 33 is fork-shaped and has two eyelets 36 . The support rail 18 and/or the swivel arm 6 can be arranged between the eyelets 36 in the front area 33 .
