Definitions

• the invention relates to a drum having a drum pedal, said pedal being attachable to the drum by means of jaws which engage their respective sides of an edge arranged along the periphery of the drum.
• a pedal clamped to the edge of the drum is frequently used.
• the prior art uses a clamping mechanism arranged on the pedal, where a jaw adjustable about a horizontal axis ex ⁇ tends inwards over the edge of the drum, while two sta ⁇ tionary jaws extend inwards below the edge. Tightening of e.g. a wing nut, which extends through the adjustable jaw, forces said jaw down toward the edge of the drum and the underlying jaws, thereby securely clamping the pedal to the drum.
• the known principle however, has the serious drawback that the length of stroke of the pedal varies.
• the length of stroke of the pedal is deci ⁇ sive to the sound emitted by the drum and thus to the mu ⁇ sic, it is a great problem to musicians that the length of stroke cannot be kept stable.
• the invention provides a drum having drum pedal, wherein the locking mechanism ensures that the length of stroke will always be the same when the pedal is mounted, and also ensures that the length of stroke does not change in use.
• the locking mechanism ensures that the length of stroke will always be the same when the pedal is mounted, and also ensures that the length of stroke does not change in use.
• the engagement with the fixing means ensures that the pedal will always have the same position when mounted. As the engagement is maintained during the use of the drum, the length of stroke may thus be maintained unchanged all the time.
• the engagement means comprise at least one resilient element having a barb which, when the pedal is mounted on the drum, is in en ⁇ gagement with said fixing means. This results in easy and rapid mounting and removal of the pedal, while ensuring the constant length of stroke.
• said fixing means consists of two angular brackets which are mounted on the inner side of the edge arranged along the periphery of the drum such that there is a well-defined distance be ⁇ tween the brackets.
• the brackets are easy to mount on the edge of the drum, and the well-defined distance contrib ⁇ utes to ensuring the fixed position of the pedal with re ⁇ spect to the drum.
• two resilient elements having barbs are arranged on the pedal, and that these are adapted to deform to pass between the brackets on the edge of the drum so that the barbs may engage behind the brackets and thereby lock the pedal.
• said engagement means oreo- ver comprise a rigid plate of a width which corresponds to the distance between the brackets, and which extends inwards between the brackets when the pedal is mounted. This rigid plate prevents the plate from travelling lat- erally when playing the drum.
• said fixing means consists of one or more holes in the edge arranged along the periphery of the drum. This ensures that the appearance of the drum is just affected minimally, while achieving the other advan ⁇ tages associated with the invention.
• said barb or barbs will be adapted to engage said hole or holes when the pedal is mounted on the drum.
• the invention also relates to a drum pedal of the type mentioned above, which may be attached to a drum by means of jaws capable of engaging an edge arranged on the drum, at least one of said jaws comprising a resilient element having a barb.
• the resilient element ensures that, as mentioned above, the pedal may be fixed with respect to the drum and the length of stroke of the pedal will thereby be the same for each mounting and remain un ⁇ changed during play.

• Fig. 1 is a sectional view of a drum 1 which is provided with an edge 2 along its periphery.
• the drum 1 may e.g. be a bass drum, and the edge 2 is also referred to as the hoop of the drum.
• a clamping mechanism provided on a drum pedal (not shown), comprises an upper jaw 3 and two lower jaws 4.
• the upper jaw 3 extends inwards over the edge 2 of the drum, while the two jaws 4 correspondingly extend inwards below the edge 2.
• the jaws 4 are stationary, while the upper jaw 3 is adjustable about a horizontal axis 5, which may take place e.g.
• FIG. 2 is a top view of the corresponding known clamping mechanism.
• Figs. 3 and 4 show a clamping mechanism of the invention.
• the edge 2 of the drum mounts two angular brackets 7 shaped such that their one face, which is secured to the edge, curves corresponding to the edge.
• the other face of the angular bracket is straight, but bent at such an angle with the first face as to be parallel with the vertical axis of the drum when it is positioned at a spe ⁇ cific distance from said vertical axis.
• the two angular brackets 7 are secured to the edge with the curved faces directed away from each other and at such a distance to the vertical axis of the drum that both of the straight faces are parallel with said axis.
• the brackets are se ⁇ cured to the edge 2 of the drum by means of screws 8.
• the brackets In the event that the edge 2 of the drum is made of a moulded material, e.g. a plastics material, the brackets
• the attachment mechanism like the known attachment mechanism, has two lower jaws 4 which are stationary and which extend inwards below the edge 2 of the drum.
• a locking mem ⁇ ber 9 is used here.
• the locking member 9 comprises a plate 10 mounted on the frame of the drum pedal by through bolts 11. At both sides, the plate 10 has a de- formable spear 12 with a barb 13. When the pedal is mounted, the spears 12 extend inwards over the edge 2 of the drum, where they correspond with the two brackets 7 arranged thereon so that when the pedal is moved inwards toward the drum, the spears 12 of the lock will be de- formed when they meet the brackets 7.
• brackets 7 on the edge 2 of the drum ensure that once the locking member 9 is secured to the brackets 7, as de ⁇ scribed above, the position will be correct and fixed, so that the length of stroke of the drum pedal is the same each time the pedal is mounted, and does not change in use.
• the locking member 9 is merely pushed inwards between the brackets 7 so that the barbs 13 engage, whereby the locking is activated.
• the constant length of stroke of the drum pedal may be additionally secured if, as shown in fig. 6, a rigid, four-sided plate 14 is arranged below the locking member 9.
• the plate 14 has a width which corresponds to the dis- tance between the brackets 7. When the pedal is mounted on the drum, this plate 14 will extend inwards between the brackets 7 and thus additionally prevent the pedal from travelling laterally.
• Figs. 7-9 show an alternative embodiment of the inven ⁇ tion.
• two holes 15 are provided in the edge 2 of the drum.
• the function of the holes 15 cor ⁇ responds completely to that described for the brackets 7 above.
• the locking member consists of a plate 10 which is provided with a deformable spear 16 with a barb 17 at each side; however, here the barbs 17 are mounted on the spears 16 such that they face downwards and may thereby engage the holes 15 when the locking mem ⁇ ber is moved inwards over the edge 2 of the drum.
• the lower jaws 4 are unchanged with respect to the disclosure above.
• the locking member In the mounting, the locking member is moved for ⁇ wardly to the drum edge 2, and then the spears 16 will be deformed while the barbs 17 move inwards over the edge 2. When the barbs 17 reach the holes 15, they engage these, thereby securing the locking member and thus the drum pedal to the drum. When the drum pedal is to be removed again from the drum, the barbs 17 are lifted out of the holes 15 by one hand, and then the drum pedal with the locking mechanism may be removed from the drum.
