Description:

This application claims priority under 35 U.S.C. 119(e)(1) based on Applicants Provisional U.S. Patent Application Ser. No. 61/517,349 filed Apr. 18, 2011 of same title.

FIELD

The present invention resides in the field of support structures, e.g., stands for musical items such as amplifiers, electronic control heads, or the instruments themselves such as guitars or the like stringed instruments.

PRIOR ART

It is customary in many situations to simply place music amplifiers directly on the floor of a performance stage or on a table for elevating and positioning the amplifier. Such methods are subject to creating or picking up interference sounds which are then picked up by the amplifier itself and transmitted to the audience. These sounds can be generated, e.g., by vibrations of the performance auditorium floor which acts as a giant drum head, particularly during loud musical playing. Various types of stands for musical equipment have been devised but they have disadvantages such as enhancing interference sounds, or are structured in a heavy, bulky or difficult to deploy manner.

Various stand structures have also been proposed such as shown in U.S. Pats. Nos. 4,753,408; 7,296,653; 6,349,792; 5,190,254; 5,024,407; 7,264,216; 5,161,771; Des. 247,034; Des. 268,108; Des. 212,238; 2,598,128; US 2011/0017886 A1; and 3,913,877. These structures have not been found satisfactory in regard to one or more aspects of visual appearance, physical strength, ease of transport, ease of set up, vibrational sound pick up resistance, or the like.

SUMMARY OF THE PRESENT INVENTION

The present invention avoids or minimizes the above noted disadvantages by means of a stand which is light weight, visually attractive, and of marked utility for supporting an amplifier or like musical equipment and attendant electronic devices, wherein the stand comprises a base having a pair of side members providing a pair of front legs and a pair of shorter rear legs and supporting (1) a forward substantially planar platform which is slanted from front to rear, and (2) a rearward spanner member, a back rest pivotally mounted on the side members for being pivoted from a closed (stored) position adjacent the top of the platform to an open operative position at substantially 90° to the platform, cooperating stop means on the spanner member and the back rest for positioning the backrest in its open operative position, and wherein all of the floor contacting leg ends terminate in a line surface whereby transmission to the stand and to an amplifier thereon of sound waves emanating from a floor are minimized. The various parts of the present stand are preferably of artistically crafted and finished hardwoods.

Referring to the drawings comprises a base 20 having a substantially planar platform 22 having front 24, rear 26 and side 28 edges and downwardly depending sides 30,31 affixed to the side edges of the platform 22, wherein a front portion 32 of each side provides a front leg, wherein a rear portion 34 each side provides a rear leg, and wherein the bottom of each leg is shaped to provide a lateral line contact surface with a floor 36 to minimize sound wave transmission from the floor to the stand and to an amplifier thereon. The stand further has a substantially rectangular back rest 38 having sides 39 with side portions 40 extending downwardly from its lateral portion 42 to provide pivot sections. Cooperating pivot bearing 44 and pivot shaft 46 means on each section and on a rear portion of an adjacent side of the base allows the back rest to pivot forwardly to a downwardly closed position adjacent the platform and to pivot upwardly and rearwardly to a substantially vertical position relative to the plane 47 of the platform. Cooperating stop shoulders 48 on the base sides and 50 on the lateral portion of the back rest are provided for stopping the back rest in a substantially vertical position.

An item support shelf 52 extends between and affixed to the base sides and is spaced below the platform 22 and extends from the front of the base toward the rear of the base to provide a storage area 54. The area has a generally rectangular access opening 56 at the front of the base, and a generally rectangular closure panel 58 is pivotally mounted to and at the front lower portions of the base sides for allowing the closure panel to pivot upwardly from or downwardly to adjacent a base supporting floor 36 to open or close the access opening. Cooperating fastener means such as straps 62 affixed on the base sides and snap fasteners 60 affixed on the closure member are provided for retaining the closure member in a closed position. Shoulder means 64 is provided on the inner surface of the closure member for supporting a musical instrument such as a guitar 66 in an upright position when said closure member is shown in its open position (see FIG. 6) and resting on a supporting floor 36.

Felt or the like cushioning strips such as 68 are affixed to structures of the stand which come into contact with musical items. The upper portion of panel 58 is cavitated as at 70 to provide a toe hold 72 which a person can grip with the toe of his shoe and pull the panel down to its open position whereby, e.g., a guitarist can temporarily place his guitar in stand-by position as shown in FIG. 1.

Referring to FIGS. 1-3 and 11A, a table top 74 with front stop 75 is provided as a preferred embodiment of the present invention and is structured to be placed on top of an amplifier 76 and provides a flat horizontal surface 78 for supporting, e.g., an amplifier head 80. Wedge shaped sides 82 and 82A are cut to the proper angle to provide 74 with a horizontal item supporting posture. It is noted that storage area 54 is dimensioned to slidingly receive table top 74 for storage, e.g., during transport.

Referring to the embodiment of FIGS. 5 and 5A, the back rest is constructed with a tie member 84 affixed to top portions of sides 39, wherein a slot 86 is provided in each member 84 for slidingly receiving cross member 88 on the back of which is mounted an electrical fan 89, preferably battery operated, for cooling the amplifier. Member 88 is locked into a desired up or down adjusted location in the slots by set screws 90 or equivalent means.

The straps (fastener means) preferably leather 62 and 92 preferably are provided with quick disconnect snap fasteners and the shoulder strap preferably is connected to the rear portions of the base sides by, e.g., Button shaped projections 94 on the sides and button holes 96 on the heavy leather carrying strap ends 98.

The invention has been described in detail with particular reference to preferred embodiments thereof, but it will be understood that variations and modifications will be effected within the spirit and scope of the invention.
