Description

Technical Field

[0001] The utility model relates to a connecting rod for a jazz drum pedal, in particular to a stretching rod which can limit the stretching length of the stretching rod during adjustment so that the stretching rod will not be separated from the connecting rod. Background Art

[0002] In jazz drum performance, double pedaling is a common technique, usually used in situations that require fast and continuous stepping actions. A double pedal usually consists of two pedals and a connecting rod. Each pedal controls a different drumstick to strike the drumhead. In order to allow the drummer to use both the left and right foot pedals to control the drumsticks to strike the same bass drum, therefore, a connecting rod needs to be set between the pedals and the drumsticks. Thus, the drummer can operate the two pedals with the left and right feet respectively to achieve richer rhythm and tone variations.

[0003] Among them, in order to meet the needs of different drummers for the distance between the left and right feet, an adjustable stretching rod is usually equipped in the connecting rod. The user can change the distance between the two pedals by stretching the stretching rod to meet personal comfort and performance needs. However, most of the current connecting rod adjustment methods on the market only use a limiting member to fix the stretching rod, which makes it easy for the user to stretch the stretching rod too long when adjusting the stretching rod, resulting in the stretching rod falling off the connecting rod and bringing trouble to the user in use. Summary of the Invention

[0004] The main purpose of the utility model is to improve the structural form of the connecting rod, and to provide a connecting rod for a jazz drum pedal, so that when the user adjusts the length of the connecting rod, the internal stretching rod can be stretched and will not be separated from the connecting rod, so that the stretching length of the stretching rod is limited within a fixed length.

[0005] The secondary purpose of the utility model is to provide a connecting rod for a jazz drum pedal. By setting scale marks on the surface of the connecting rod, the user can identify the stretching length of the stretching rod, so that the user can accurately adjust to the target length during each adjustment process.

[0006] To achieve the foregoing purposes, the utility model provides a connecting rod for a jazz drum pedal, comprising: a tube body, a stretching rod, a limiting member and an indicating member.

[0007] Preferably, the tube body forms an insertion channel along an axial direction. The tube body has a locking hole and an anti - detachment concave hole communicating with the insertion channel, and a scale mark is formed on the surface of the tube body adjacent to the anti - detachment concave hole; the stretching rod is inserted into the insertion channel along the axial direction, so that a partial length of the stretching rod is inserted into the tube body, and the stretching rod is provided with a positioning portion facing the anti - detachment concave hole; the limiting member is arranged in the locking hole and can selectively press against the stretching rod to prevent the stretching rod from relatively displacing in the insertion channel, or loosen the stretching rod so that the stretching rod can freely move in the insertion channel; the indexing member is inserted into the anti - detachment concave hole to connect the positioning portion, and a part of the length of the indexing member overlaps the inside of the anti - detachment concave hole, so that the indexing member can move between a first position at one end of the anti - detachment concave hole and a second position at the other end of the anti - detachment concave hole.

[0008] Preferably, when the stretching rod is stretched, the indexing member always remains in the anti - detachment concave hole, so that a stretching length of the stretching rod is limited to an interval length between the first position and the second position.

[0009] In addition, a cross - section of the insertion channel is set as a polygon, and a cross - section of the stretching rod is also set as the polygon to match the insertion channel, so that the stretching rod cannot rotate relative to the tube body after being inserted.

[0010] Preferably, the indexing member has a head, a neck and a connecting portion. The head is larger than the width of the anti - detachment concave hole; the connecting portion and the neck are smaller than the width of the anti - detachment concave hole. Among them, the indexing member has a groove that can be used in cooperation with a hand tool, and the groove cooperates with the scale mark to display the stretching length. In addition, the indexing member has an alignment index that can cooperate with the scale mark to display the stretching length.

[0011] Preferably, the connecting rod further has an auxiliary stretching rod, an auxiliary limiting member, and an auxiliary indicating member. The tube body has an auxiliary locking hole and an auxiliary anti-disengagement concave hole communicating with the insertion channel, and an auxiliary scale mark is formed on the surface of the tube body adjacent to the auxiliary anti-disengagement concave hole. The auxiliary stretching rod is inserted into the insertion channel along the axial direction, such that a partial length of the auxiliary stretching rod is inserted into the tube body, and the stretching rod and the auxiliary stretching rod are respectively disposed on opposite sides of the tube body. The auxiliary stretching rod is provided with an auxiliary positioning portion facing the auxiliary anti-disengagement concave hole. The auxiliary limiting member is disposed in the auxiliary locking hole and can selectively press against the auxiliary stretching rod to prevent the auxiliary stretching rod from relatively displacing in the insertion channel, or release the auxiliary stretching rod such that the auxiliary stretching rod can freely move in the insertion channel. The auxiliary indicating member is inserted into the auxiliary anti-disengagement concave hole to connect with the auxiliary positioning portion, and a partial length of the auxiliary indicating member overlaps with the inside of the auxiliary anti-disengagement concave hole. Wherein, when the auxiliary stretching rod is stretched, the auxiliary indicating member always remains in the auxiliary anti-disengagement concave hole, such that an auxiliary stretching length of the auxiliary stretching rod is limited within the length from one end to the other end where the auxiliary indicating member abuts against the auxiliary anti-disengagement concave hole.

[0012] Preferably, a plurality of tube walls are formed on the outer wall of the tube body, and the locking hole and the auxiliary locking hole are opened in one of the plurality of tube walls, while the anti-disengagement concave hole and the auxiliary anti-disengagement concave hole are opened in another one of the plurality of tube walls.

[0013] The feature of the present utility model is that the tube body has the anti-disengagement concave hole communicating with the insertion channel, and the indicating member can be fixed to the positioning portion of the stretching rod through the anti-disengagement concave hole. At this time, a partial length of the indicating member overlaps with the inside of the anti-disengagement concave hole. Therefore, when the stretching rod is stretched along the axial direction, the indicating member always remains in the anti-disengagement concave hole, such that the stretching length of the stretching rod is limited and the stretching rod will not be stretched too long to disengage from the tube body.

Detailed implementation manners

[0022] The present invention will be further described below in conjunction with specific embodiments and drawings, and the advantages and features of the present invention will become clearer as the description proceeds.

[0023] Please refer to Figure 1 As shown, the present utility model provides a connecting rod 1 of a drum set pedal, which is mainly connected between an auxiliary pedal 90 of a drum set and an auxiliary drumstick 91. The auxiliary pedal 90 of the drum set can drive the connecting rod 1 to rotate by a user stepping on it, and cause the auxiliary drumstick 91 to swing and strike a bass drum (not shown in the figure). Thus, the user can respectively set the auxiliary pedal 90 of the drum set and a main pedal 92 of the drum set on the left foot and the right foot, and set the auxiliary drumstick 91 coordinated with the auxiliary pedal 90 of the drum set and a main drumstick 93 coordinated with the main pedal 92 of the drum set on the same bass drum, so that the user can perform a double - pedal playing method.

[0024] Please refer to Figure 2 And Figure 3As shown, the connecting rod 1 in the first preferred embodiment includes: a tube body 20, a tension rod 30, a limiting member 40, and an indicating member 50. The tube body 20 forms an insertion channel 21 along an axial direction. The insertion channel 21 has a first insertion opening 211 and a second insertion opening 212 respectively provided on both sides of the tube body 20. In the first preferred embodiment, one end of the tube body 20 having the second insertion opening 212 is connected to a second universal joint 61. The tube body 20 has a locking hole 22 and an anti - detachment concave hole 23 communicating with the insertion channel 21, and a scale mark 24 is formed on the surface of the tube body 20 adjacent to the anti - detachment concave hole 23. One end of the tension rod 30 is connected to a first universal joint 60 and the other end is inserted into the first insertion opening 211 along the axial direction, so that a partial length of the tension rod 30 is inserted into the tube body 20, and the tension rod 30 is provided with a positioning portion 31 facing the anti - detachment concave hole 23. The limiting member 40 is disposed in the locking hole 22 and can selectively press against the tension rod 30 to prevent the tension rod 30 from relatively displacing in the insertion channel 21, or release the tension rod 30 so that the tension rod 30 can move freely in the insertion channel 21. The indicating member 50 is inserted into the anti - detachment concave hole 23 to connect to the positioning portion 31, and a partial length of the indicating member 50 overlaps inside the anti - detachment concave hole 23, so that when the tension rod 30 is stretched, a partial length of the indicating member 50 will always remain in the anti - detachment concave hole 23, and the tension rod 30 will also always remain in the insertion channel 21.

[0025] Wherein, a cross - section of the insertion channel 21 is set as a polygon, and a cross - section of the tension rod 30 is also set as the polygon to match the insertion channel 21, so that the tension rod 30 cannot rotate relative to the tube body 20 after being inserted. In addition, the outer wall of the tube body 20 is formed with a plurality of tube walls to match the polygon, and the locking hole 22 and the anti - detachment concave hole 23 are respectively opened in two of the plurality of tube walls. As Figure 2 shown, when the user uses it, the locking hole 22 is opened on the top surface 25 facing upward of one of the plurality of tube walls, so that the user can adjust it conveniently; and the anti - detachment concave hole 23 is opened on an adjacent surface 26 adjacent to the top surface 25 of one of the plurality of tube walls, so that the user can identify the indicating member 50, the anti - detachment concave hole 23, and the scale mark 24 by lowering the head.

[0026] Please refer to again Figure 3As shown, the indexing member 50 further has a head 51, a neck 52 and a connecting portion 53. The head 51 is larger than the width of the anti - detachment concave hole 23; the connecting portion 53 and the neck 52 are smaller than the width of the anti - detachment concave hole 23, so that the indexing member 50 can be inserted from the anti - detachment concave hole 23 and located at the positioning portion 31 of the stretching rod 30, and the neck 52 can be received in the anti - detachment concave hole 23, while the head 51 is exposed outside the anti - detachment concave hole 23. In addition, the indexing member 50 further has a groove 54 that can be used in cooperation with a hand tool and an alignment index 55 that can cooperate with the scale marking 24 to display the stretching length. In the first preferred embodiment, the groove 54 simultaneously has the function of the alignment pointer 55, and the user can display the stretching length by the groove 54 cooperating with the scale marking 24.

[0027] Among them, the indexing member 50 is not limited to the implementation mode of the first preferred embodiment. The indexing member 50 can also be composed only of the neck 52 and the connecting portion 53, and the groove 54 and the alignment index 55 are arranged on the neck 52; and the connection between the connecting portion 53 and the positioning portion 31 is not limited to the screw connection method, as long as the alignment index 55 can cooperate with the scale marking 24 to display the stretching length after the indexing member 50 is installed.

[0028] Please refer to Figure 4A and Figure 4B As shown, in the first preferred embodiment, when the stretching rod 30 is shortened inward to the shortest, the indexing member abuts against a first position A1 at the innermost side of the anti - detachment concave hole 23, and the groove 54 will point to a minimum value in the scale marking 24; when the stretching rod 30 is stretched outward, the user only needs to separate the limiting member 40 from the stretching rod 30, and the stretching rod 30 can move freely in the insertion channel 21. When the stretching rod 30 is stretched outward until the indexing member 50 abuts against a second position A2 at the outermost side of the anti - detachment concave hole 23 with an interval length, the groove 54 will point to a maximum value in the scale marking 24. Therefore, the stretching length of the stretching rod 30 is limited to an interval length between the first position A1 and the second position A2.

[0029] Please refer to Figure 5 、 Figure 6As shown, in the second preferred embodiment, the difference from the first preferred embodiment is only that the tube body 20 can accommodate an auxiliary stretching rod 70, and the rest of the structure is the same as that of the first preferred embodiment, so it will not be repeated here. The connecting rod 1 further includes the auxiliary stretching rod 70, an auxiliary limiting member 71, and an auxiliary indicating member 72. The tube body 20 has an auxiliary locking hole 73 communicating with the insertion channel 21 and an auxiliary anti-disengagement concave hole 74, and an auxiliary scale mark 75 is formed on the surface of the tube body 20 adjacent to the auxiliary anti-disengagement concave hole 74.

[0030] Wherein, one end of the auxiliary stretching rod 70 is connected to the second universal joint 61, and the other end is inserted into the second insertion port 212 along the axial direction, so that a partial length of the auxiliary stretching rod 70 is inserted into the tube body 20, and the auxiliary stretching rod 70 is provided with an auxiliary positioning portion 76 facing the auxiliary anti-disengagement concave hole 74; the auxiliary limiting member 71 is disposed in the auxiliary locking hole 73 and can selectively press against the auxiliary stretching rod 70 to prevent the auxiliary stretching rod 70 from relatively displacing in the insertion channel 21, or release the auxiliary stretching rod 70 so that the auxiliary stretching rod 70 can freely move in the insertion channel 21.

[0031] The auxiliary indicating member 72 is inserted into the auxiliary anti-disengagement concave hole 74 to connect the auxiliary positioning portion 76, and a part of the length of the auxiliary indicating member 72 overlaps the inside of the auxiliary anti-disengagement concave hole 74. When the auxiliary stretching rod 70 is stretched, the auxiliary indicating member 72 will always remain in the auxiliary anti-disengagement concave hole 74, so that an auxiliary stretching length of the auxiliary stretching rod 70 is limited within the length from one end to the other end where the auxiliary indicating member 72 abuts against the auxiliary anti-disengagement concave hole 74.

[0032] In addition, the locking hole 22 and the auxiliary locking hole 73 are commonly opened on the top surface 25 of the plurality of tube walls, and the anti-disengagement concave hole 23 and the auxiliary anti-disengagement concave hole 74 are commonly opened on the adjacent surface 26 of the plurality of tube walls.

[0033] In summary, by providing the indicating member 50 on the stretching rod 30 that can cooperate with the anti-disengagement concave hole 23 in the present invention, when the user adjusts the length of the stretching rod 30, the stretching rod 30 will not be stretched too long and separated from the tube body 20, and the indicating member 50 can also cooperate with the scale mark 24 to display the stretching length.

[0034] The above description is illustrative rather than restrictive to the present invention. Those of ordinary skill in the art can understand that without departing from the spirit and scope defined by the present invention, many modifications, changes or equivalents can be made, but all will fall within the protection scope of the present invention.
