Bass drum spur system

Abstract

A bass drum spur system has a pivot assembly and a spur leg assembly. The pivot assembly has a spur hub removably attachable to a rim of a drum and a hub cover attached to the spur hub. The hub cover has a passageway and a circumferential slot formed through a sidewall of the passageway. The circumferential slot has first and second notches at respective opposite ends of the slot. A release button is axially slidable within the passageway of the hub cover and a spring is disposed in the passageway and biases the release button in a direction away from the spur hub. The spur leg assembly has a post fixedly attached to the release button for movement therewith, wherein the post is movable between engagement with the first notch and the second notch by pressing the release button in a direction toward the spur hub and rotating the post along the circumferential slot.

DETAILED DESCRIPTION OF THE INVENTION

(8) With reference now to the drawings, and in particular to FIGS. 1-6 thereof, the preferred embodiment of the new and improved bass drum spur system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

(9) The present invention, the bass drum spur system has a plurality of components. Such components are individually configured and correlated with respect to each other to attain the desired objective. In their broadest context, the present invention is bass drum spur system comprising a bass drum having first and second rims with a first and second heads.

(10) Next is a pivot assembly including a spur hub with apertures and with bolts for coupling the spur hub to a rim. The pivot assembly includes a hub cover having a cylindrical passageway formed with a notch. The pivot assembly includes a release button axially slidable within the hub cover. The pivot assembly includes a spring urging the release button away from the spur hub and the first rim.

(11) Provided next is a foot having a foot pad with a central bore. A downwardly extending finger and an upwardly extending projection are positioned within the central bore. Lastly, a spur leg assembly is provided. Such spur leg assembly has a sleeve with a sleeve aperture and with a long axial slot beneath the sleeve aperture. The spur leg assembly has an insert. A recess is formed in a lower end and with a short axial slot. A lower bolt extends through the short axial slot adjustably coupling the spur to the sleeve. The spur leg assembly has a stem. A central bolt extends through the long slot adjustably coupling the stem to the sleeve. An upper bolt couples the button to the stem.

(12) From a specific viewpoint, the present invention is a bass drum spur system 10 for fixedly positioning a bass drum 12 during use and for facilitating the movement of the bass drum when not in use. The positioning and the facilitating are done in a safe, convenient, and economical manner. The system includes the bass drum 12. The bass drum has a vertically oriented first rim 14 with a first head 16 and a vertically oriented second rim 18 with a second head 20. The first and second rims and the first and second drumheads have a common horizontal axis.

(13) Two pivot assemblies 24 are provided with each pivot assembly including a spur hub 26 with a plurality of apertures 28. The apertures having a plurality of bolts 30 for coupling the spur hub to the first rim at opposed locations. Each pivot assembly 24 includes a hub cover 32 with a cylindrical passageway 34 and a circumferential slot 35 formed through the sidewall of the passageway. The circumferential slot 35 is formed with semi-cylindrical notches 36 and 37 at opposite ends of the slot. Each pivot assembly 24 includes a release button 38 axially slidable within the hub cover. Each pivot assembly 24 also includes a coil spring 40 urging the release button away from the spur hub and the first rim.

(14) Provided next are two feet 44, each having an elastomeric foot pad 46. Each foot and the foot pad are vertically oriented with a central bore 47 and with a downwardly extending finger 48 within each central bore. Next, an upwardly extending projection 50 is within each central bore.

(15) Lastly provided are two adjustment assemblies 54. Each spur leg assembly has a sleeve 56 formed as a hollow cylinder with an upper end and a lower end. Each sleeve has a sleeve aperture 58 adjacent to the upper end with a long axial slot 60 beneath the sleeve aperture. Each spur leg assembly has an insert 64 formed as a cylinder with an upper end and a lower end. A recess is formed in the lower end with a short axial slot 66. A lower bolt 68 extends through each short axial slot adjustably coupling a spur to a sleeve.

(16) Each spur leg assembly has a post 70 formed as a cylinder with an upper end and a lower end, the upper end fixedly attached the release button 38. A central bolt 72 extends through the long slot adjustably coupling the post 70 to the sleeve. A bolt 74 couples a button 38 to the post 70 whereby rotation of the spur leg assembly to a raised inoperative position will locate the post in the notch 36 and locate the fingers above a support surface 76 to facilitate moving the drum and whereby the rotation of the adjustment to a lowered operative position will locate the post in notch 37 and locate the fingers in contact with a support surface 76 to facilitating playing the drum.

(17) While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the following claims.
