Description

Technical Field

[0001] This utility model relates to a striking pedal, and more particularly to a transmission structure for the striking pedal to pull the guide cable. Background Technology

[0002] The cajon looks like a stool. You can sit on it and strike different parts to produce different sounds, making it very suitable for improvisation. The cajon is constructed like an empty wooden box, with a round hole at the back for sound output, and a rattle inside the front of the box to produce a snare drum-like sound.

[0003] For example, US Patent No. 8,624,097, "Catalogue Drum Percussion Device," discloses a catalogue drum percussion device that can be used as an auxiliary percussion method to increase the convenience and variety of percussion. The percussion pedal of this catalogue drum percussion device mainly transmits force through a guide cable. By stepping on the foot pedal, the guide cable is pulled, which in turn drives the percussion stick to strike the catalogue drum.

[0004] To protect the guide cable, it is inserted into the conduit. However, in this patented technology, to increase torque, the guide cable is connected to a support rod. The torque is increased by leveraging the support rod. However, the angle at which the guide cable enters the conduit changes due to the rotation of the support rod, causing the guide cable to rub against the conduit continuously. This makes the conduit prone to breakage and requires frequent maintenance. Utility Model Content

[0005] The main purpose of this invention is to disclose a wooden box drum percussion device that prevents the guide cable from excessively rubbing against the guide tube, thereby avoiding damage to the guide tube and reducing the maintenance needs of the wooden box drum.

[0006] To achieve the above objectives, this utility model provides a striking pedal capable of changing the pulling angle of the guide cable, comprising a pedal frame, a foot pedal, a support rod, a chain, and a cable sleeve. The pedal frame is pivotally connected to a rotating rod, allowing the rod to rotate. The foot pedal drives the rotating rod to rotate. One end of the support rod is fixed to the rotating rod, and one end of the chain is pivotally fixed to the other end of the support rod. The cable sleeve passes through a guide cable, which has a starting end and an ending end. The cable sleeve is fixed to the pedal frame, and the starting end of the guide cable is pivotally fixed to the other end of the chain.

[0007] In one embodiment of the present invention, a crossbar is fixed to the rotating rod in the direction of the vertical axis, and the foot pedal is fixed to the end of the crossbar away from the rotating rod by a belt.

[0008] In one embodiment of the present invention, the crossbar has a groove in which the belt is accommodated.

[0009] In one embodiment of this utility model, the pedal stand has a support rod, and the cable sleeve is fixed to the support rod.

[0010] In one embodiment of the present invention, an L-shaped plate is fixed to the pedal stand, the L-shaped plate having an extension portion away from the pedal stand, and the support rod is fixed to the extension portion.

[0011] In one embodiment of this utility model, a reinforcing fixing plate is also fixed between the support rod and the pedal stand.

[0012] In one embodiment of this utility model, the support rod is screwed into a directional ring, and the sleeve passes through the directional ring and is fixed by the screwing of two nuts.

[0013] In one embodiment of the present invention, the beginning of the guide cable is locked to a locking sleeve, which is fixed to the other end of the chain. Attached Figure Description

[0019] The detailed contents and technical description of this utility model are further illustrated by the embodiments below. However, it should be understood that these embodiments are for illustrative purposes only and should not be construed as limiting the implementation of this utility model.

[0020] Please see " Figure 1 "", Figure 2 "", Figure 3A "and" Figure 3B As shown, this utility model is a striking pedal capable of changing the pulling angle of the guide cable, comprising a pedal stand 10, a foot pedal 20, a support rod 30, a chain 40, and a line sleeve 50. The pedal stand 10 is pivotally connected to a rotating rod 11, allowing the rotating rod 11 to rotate. In practice, the rotating rod 11 can be pivotally connected to the pedal stand 10 via two pivots 12, and can rotate relative to the pedal stand 10.

[0021] The foot pedal 20 drives the rotating rod 11 to rotate. In one embodiment, a crossbar 13 is fixed to the rotating rod 11 in the direction perpendicular to the axial direction, and the foot pedal 20 is fixed to the end of the crossbar 13 away from the rotating rod 11 by a belt 21. Thus, as long as the foot pedal 20 is stepped on, a torque is applied to the rotating rod 11 through the belt 21 and the crossbar 13, causing the rotating rod 11 to rotate. Preferably, the crossbar 13 may have a groove 131, and the belt 21 is accommodated in the groove 131 to prevent the belt 21 from shifting and falling off.

[0022] One end of the support rod 30 is fixed to the rotating rod 11, and one end of the chain 40 is pivotally fixed to the other end of the support rod 30. Thus, there is a lever distance L between the chain 40 and the rotating rod 11. When the rotating rod 11 rotates, the displacement of the chain 40 can be increased through the lever action.

[0023] Please also refer to " Figure 4 As shown, the cable sleeve 50 is fitted with a guide cable 51, which has a starting end 511 and an ending end 512. The cable sleeve 50 is fixed to the pedal stand 10, and the starting end 511 of the guide cable 51 is pivotally fixed to the other end of the chain 40, while the ending end 512 of the guide cable 51 is connected to a striking device 60 to drive a striking rod 61. Thus, when the chain 40 moves, it can drive the guide cable 51 to move and rotate the striking rod 61, thereby striking a wooden box drum 70.

[0024] like" Figure 1 As shown, in one embodiment, the pedal stand 10 has a support rod 14, and the cable sleeve 50 is fixed to the support rod 14. The pedal stand 10 can also be fixed with an L-shaped plate 15, which has an extension 151 located away from the pedal stand 10, and the support rod 14 is fixed to the extension 151. Preferably, a reinforcing fixing plate 16 can also be fixed between the support rod 14 and the pedal stand 10, making the support rod 14 more firmly connected and fixed to the pedal stand 10.

[0025] Furthermore, the support rod 14 can be screwed onto a directional ring 17, through which the cable sleeve 50 passes and is fixed by the engagement of two nuts 18. This fixes the cable sleeve 50 so that it faces the other end of the support rod 30. Additionally, for ease of maintenance and replacement of the guide cable 51, the starting end 511 of the guide cable 51 is designed to be locked to a locking sleeve 52, which is fixed to the other end of the chain 40.

[0026] Please also refer to " Figure 2 "", Figure 3A "and" Figure 3BAs shown, when the foot pedal 20 is stepped on, causing the rotating rod 11 to rotate and thus the support rod 30 to move, due to the flexible nature of the chain 40, when the support rod 30 is moved from " Figure 3A "Turn to" Figure 3B When the cable 51 is in the " " position, the chain 40 will bend accordingly, while keeping the angle at which the guide cable 51 enters the sleeve 50 unchanged. In this way, the guide cable 51 can avoid excessive friction with the sleeve 50.

[0027] In summary, the advantages of this utility model compared to conventional methods are as follows:

[0028] 1. Connect the guide cable and the support rod with the chain. The chain has a flexible property, so that the angle at which the guide cable enters the sleeve remains constant, thus avoiding excessive friction between the guide cable and the sleeve.

[0029] 2. Set the L-shaped plate to fix the pedal stand, and screw the directional ring on the pedal stand. The directional ring can fix the cable sleeve, so that the cable sleeve faces the other end of the support rod, so that the guide cable passes through the cable sleeve at the best angle.
