Abstract

Cajon pedal with horizontal mallet movement, characterized in that the beater movement is not as usual vertically, but horizontally.

Description

The Cajon is a compact, easy to transport, versatile percussion instrument, which enjoys growing popularity. In order to expand the sound possibilities of the Cajon, there are meanwhile extensive special accessories z. Claves, bells, bells etc .. Especially with the Cajon pedals, which allow the production of bass beats by foot, there is a wide range. The pedals according to the current state of the art is intrinsically that the mallet performs its movement vertically on a horizontal shaft. This principle has the great disadvantage that the mallet attaches relatively high to the cajon. This unfavorable position of the beater is unavoidable in the previously known systems, since the mallet requires a certain length of about 10-20 cm to develop the required momentum for a percussive game. Shortening the mallet reduces the swing kinematics to unplayability. This technical conflict of objectives means that a large area of the Cajon playing surface can not be played with as if desired and intended by the hands, as the far-reaching mallet and the seesaw construction of the Cajon pedal is in the way. A full-fledged recording with the classic variant-rich Cajon playing techniques is thus much more difficult to impossible (for example, pitch bending, deep bass beats, angling the cajon, etc.). The reason for the current unsatisfactory state of the art is the unreflected adoption of the available pedal technology from the field of bass drum application of a conventional drum set. In the case of the drum set, the active principle is not a problem, since the bass drum is usually played exclusively with the bass drum pedal and not additionally with the hands.

The limitations and disadvantages of the conventional mallet drive systems are avoided by the present invention "Cajon pedal with horizontal mallet motion". The use of a standard pedal by means of a suitable adapter is based on utility model no. DE 20 2010 004 042 U1 2010.08.05 and is not described again as a known state of the art here.

The invention makes it possible to strike the mallet on the lower part of the cajon. It is due to the special arrangement of the components no Hebelwegverkürzung the beater required, which would adversely affect its momentum kinematics.

The vertically rotatably mounted rotary column (Fig. 1, Pos. 3 ), is by means of a fixed axis (Figure 1, Pos. 2 ) on the holding block (fig. 1, pos. 4 ) attached. The retaining block is fastened by means of a fastening element (Fig. 1, Pos. 5 ) rigid on the rail (fig. 1, pos. 12 ) attached. The support block with the mounted rotary column can be swiveled by 90 ° for space-saving transport. For this purpose, the loosening and tightening of the fastener (Figure 1, Pos. 5 ) required. The pack size is thus only marginally larger than that of a conventional single-bass drum pedal. Alternatively, it is possible by design, the rail (Figure 1, Pos. 12 ) turned 90 ° to the pedal plate (picture 1, pos. 16 ) postpone. This also causes a very compact pack size, as a result, the rotary column is positioned in a plane parallel to the pedal plate and no longer interfering protrudes.

The beater unit (picture 1, pos 6 ) consists of a mallet head (Fig. 1, Pos. 8th ), Mallet (picture 2, pos. 7 ), Mallet drive lever (picture 2, pos. 9 ) and fixing sleeve (picture 2, pos. 14 ). The beater unit (picture 1, pos. 6 ) is by means of releasable fixing element (Figure 2, Pos. 15 ) on the rotary column (fig. 1, pos. 3 ) attached.

Purpose Return of the beater is on the column (fig. 1, pos. 3 ) an elastic return element (picture 1, pos. 10 ) attached. Alternatively, torsion springs, rubber cables, tension springs, etc. can be used here. This system is partly state of the art and is already used in conventional bass timpani pedals. New is the mounting position which is executed here deviating from the prior art in a horizontal position. This serves the space-saving and protected positioning of the return element.

To adapt to the optimal sound impact point of the mallet head, the mallet unit (Figure 1, Pos. 6 ) are adjusted in height along the rotary column. Likewise, the optimal angle adjustment of the mallet in relation to the clubface of the cajon is adjustable thereby. The adjustment is done by loosening and tightening the fixing element (fig. 2, pos. 15 ) on the fixing sleeve (fig. 2, pos. 14 ). As a result, the mallet unit with the rotary column is securely connected.

The lateral angular position of the pedal with respect to the cajon can be easily adapted to the ergonomic wishes of the player. For this purpose, the interconnected module consisting of standard pedal, profile rail and pedal plate (Fig. 3 Pos. 11 , Pos. 12 , Pos. 16 = simplified schematic representation) according to the cajon pivoted. This is made possible by a rotatable attachment between the profile rail (fig. 3, pos 12 ) and the bottom plate Cajon (picture 3, pos. 17 ).

The principle of horizontal mallet movement allows for both use right-footed or left-footed use. For this purpose, only a simple turning of the mallet unit (Figure 2, detail 1) and a corresponding pivoting of the bottom plate cajon (Figure 1, Pos 17 ) required. This conversion can be done without tool use.

Claims (7)

Cajon pedal with horizontal mallet movement characterized in that the beater movement is not as usual vertically, but horizontally. Cajon pedal with horizontal mallet movement according to claim 1, characterized in that the horizontal mallet movement by a rotary column (Figure 1, pos. 3 ) he follows. Cajon pedal with horizontal mallet movement according to claim 1, characterized in that the mallet unit (Figure 1, Pos. 6 ) along the rotary column (Fig. 1, pos. 3 ) can be moved almost to the ground down but also upwards.
