RU75495U1 - DOUBLE PEDAL DEVICE FOR ONE DRUM BASS DRUM - Google Patents

Abstract

A double pedal device for a bass drum with one mallet is proposed. As a result of using the proposed technical solution, the design of the double pedal device for the bass drum is greatly simplified and cheapened.

Description

The technical field to which the utility model relates.

The utility model relates to percussion musical instruments and,

in particular, pedals for playing the bass drum.

A device for a double pedal for a bass drum with two beater, model Maxtone DP-992C, manufactured by Maxtone, containing a base in the form of a metal plate 1, a platform for the foot 2 and the platform for the heel 3, which together make up the pedal, two racks 4 on which axis 5 is mounted with fasteners for beater 6, beater 7, spring assembly 8, belt (or chain) drive 9, an emphasis 10 is mounted in the center under the foot platform to the metal plate, connecting the platform under the metal frame 11 heel 3 with a rack of a belt (or chain) power drive 12, on which a belt (chain) drive 9 is attached, connected via a roller of the power drive 13 with the fastening of the beater 6. No corresponding printed publication describing the prototype was found, therefore, a prototype drawing is presented in the drawings section ( figure 1) and two photos of the prototype (figure 2 and figure 3). The specified device is the closest in technical essence to the prototype of the proposed utility model. The disadvantage of the device, which is the prototype, is the complexity of the design.

Utility Model Essence

The objective of the proposed technical solution is to create a simpler in its design and therefore cheaper device of the double pedal for a bass drum with one beater.

Utility Model Disclosure

The specified technical result is achieved by the fact that the proposed device of the double pedal for the bass drum with one beater includes a metal frame connecting the pedal, consisting of a platform for the foot and the thrust plate, with two uprights, on which the axis with the mount for the beater, one beater, spring a node along the racks, a belt (or chain) drive connecting the pedal toe with a beater mount, a thrust axis that is attached to the foot platform perpendicular to its longitudinal axis, protrusions of the thrust axis on which s set cushioning pads, thrust frame,

which, on the one hand, is attached to the base of two racks, then rests on the protrusions of the thrust axis and at a distance of about 3-5 centimeters above the thrust bearing, on which the shock-absorbing base is mounted, ends with a platform for the heel.

Utility Model Implementation

Figure 4 presents the design diagram (side view). A metal frame 14 connects the pedal, consisting of a platform for the foot 15 and the thrust bearing 16, with two struts 17, on which the axis 18 is mounted for fastening the beater 19, on which one beater 20 is mounted. The spring assembly 21 is placed along the struts 17, belt (or chain) drive 22 connects the toe of the pedal with the mount for the beater 19. When you press the feet on the platform for the feet 15, the pedal moves down and pulls the belt (or chain) drive 22, which pulls the mount for the beater 19, resulting in a mount for the beater cranking length along the axis 18 and thus the mallet moves towards the bass drum (not shown in the figure), the mallet hits the surface of the bass drum. Thanks to the spring unit 21, the beater returns to its original position. In order to increase the rate of impact of the beater on the bass drum, a thrust frame 24 is attached to the base of the struts 23, which then rests on the protrusions of the thrust axis 25 on which shock absorbing pads are installed (not shown), and at a distance of the order of 3-5 centimeters above the thrust bearing 16, on which the shock-absorbing base 26 is mounted, ends with the platform for the heel 27. Thanks to this design, the clapper hits the bass drum not only by pressing the feet on the platform for the feet 15, but also by pressing the heel on the platform for I heel 27. The heel pad 27 moves down to the abutment with the thrust bearing 16, thrust frame 24 abuts against the abutment projections axis 25 which presses the pad to

feet 15, as a result of which the platform for the feet 15 moves downward, bringing the beater 20, which hits the bass drum, using the mechanism already described above. Thus, by alternately pressing the foot on the platform for the foot 15 and the heel on the platform for the heel 27, the beat rate of one beater on the bass drum doubles.

Figure 5 presents a diagram of the design of the device (top view). For a more accurate understanding of the design of the device, the figure schematically shows the location of the nodes of the proposed device of the double pedal for a bass drum with one beater.

Figure 6 presents a photograph of the proposed device double pedal for a bass drum with one beater, which proved that the pace of impact of the beater on the bass drum can be doubled using only one beater.

Industrial applicability

The proposed utility model greatly simplifies and cheapens the design of the device of the double pedal for the bass drum.

Claims (1)

A double pedal device for a bass drum with one beater, including a foot platform and a heel platform that interact with each other, which together make up the pedal, two stands, on which an axis with a beater mount is mounted, at least one beater, a spring unit, a belt (or chain) drive connecting the pedal toe with a beater mount, characterized in that a thrust frame is mounted to the base of the struts, which rests on the protrusions of the thrust axis, and at a distance of about 3-5 cm above the thrust bearing on which mortiziruyuschee base ends pad for the heel, wherein the thrust axis is attached to the pad for the foot perpendicular to the longitudinal axis of the pad for the foot and on the projections on the thrust axis, or the thrust frame at the point of contact with the abutment protrusions axis set cushioning pads.
