3,173,642 MUSICAL INSTRUMENT STAND Sidney A. Greenspan, 8236 Christina Ave., Skolrie, Iii. Filed Apr. 29, 1963, Ser. No. 276,526 1 Claim. (Cl. 248-170) My invention relates to new and useful improvements in musicalinstrument stands and has for its object the provision of an improved structure of the character hereinafter described which will be highly efiicient in use and economical in manufacture.
While my invention is shown as a drum support, it is to be understood that it is not to be so limited. A principal object of the invention is to provide an instrument-supporting stand which may be adapted to support a variety of sizes of instruments of the type for which it is constructed, with firmness and rigidity and in a manner such that the instrument will not vibrate or bounce when being played.
Another and equally important object of the invention is to provide in a musical instrument stand a standard which may be folded relative to a base when moved from and into instrument-supporting position. In such an instrument stand, it is essentially necessary that when the standard is folded with respect to the base in instrumentsupporting position, that it be substantially rigid and re strained from vibrating during playing of the instrument. It is therefore one of the objects of this invention to provide a simple arrangement for effecting rigidity between the base and the standard when the latter is folded relative to the base into instrument-supporting position.
In a musical instrument stand for the character hereinafter described, the supporting head of the stand is generally provided with radially disposed arms which are mutually brought together when the supporting head is in collapsed position and folded in parallel relationship with respect to the standard of the stand. It is an object of this invention to mount one of the instrumentdrolding arms in a manner such that it may be yieldably adjusted to accommodate the head of the stand to the size of the in strument to be held thereon and to bear against the instrument under spring action so as to firmly yieldably hold the instrument upon and within the arms of the head.
Other objects will appear hereinafter.
The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:
FIG. 1 is a perspective view of a musical instrument stand having incorporated therein my invention, the stand being shown in folded position;
FIG. 2 is a perspmtive view of my musical instrument stand showing the same in extended position;
FIG. 3 is a sectional detail view taken substantially on line 3-3 of FIG.
FIG. 4 is a fragmentary sectional detail view taken substantially on line 4-4 of FIG. 3;
FIG. 5 is a plan view taken substantially on line 55 of FIG. 3;
FIG. 6 is a sectional line 6-6 of FIG. 2.
The various objects of my invention are preferably accomplished by the preferred form of construction shown in the accompanying drawings and which will now be described. In this connection, the musical instrument stand embodying my invention comprises a base It), a standard 11, and a head 12. The base comprises two circularly formed discs 13 and 14 spaced from each other and secured together by pins 15 two of which serve as pintles for the movable legs 16 which have their inner end pordetail view taken substantially on tions 17 disposed between the discs 13 and 14. A third leg 18 has its end portion 19 disposed between the discs 13 and 14 and rigidly secured thereto by the remaining two pins 15.
The outer end portions of each of the legs 16 and 18 carry caps 20 formed of plastic or other material and which serve to prevent marring or scratching the surface upon which the instrument stand is placed.
Secured by spot welding 21 or other means to the disc 14, are brackets 22 angled to provide parallelly extending upright plates 23. The standard 11 comprises telescopically arranged sections 24 and 25 secured together in an adjusted position with respect to each other by means of a suitable wing nut and bolt 26. The lower end portion 27 of the section 24 projects between the plate 23. This end portion 27 of the section 24 is slotted longitudinally as at 28. Projecting through the slotted portion 28 is a horizontal pin 29 carried by the plates 23. Press-fitted into the end portion 27 is a detent 30, the end of which extends beyond the slotted end portion 27 of the section 24 of the standard and is adapted to engage an opening 31 formed in the plate 14.
The outer end of the detent is chamfered as at 32 to facilitate its movement into and out of the opening 31. Positioned between the pin 29 and the detent 30 is a spring 33. The arrangement is such that to withdraw the detent 30 from the opening 31, the section 24 of the standard 11 is pulled upwardly relative to the plates 23 against the action of the spring 33. When the detent 30 is clear of the opening 31, the standard may be pivoted relative to the disc 14 into the position shown in FIG. 1. This is accomplished after the movable legs 16 have been pivoted in substantially parallel position with respect to the stationary leg 18. When the standard 11 is pivoted to an extended position relative to the disc 14, the spring 33 acting upon the detent 30 and pin 29, will serve to project the detent 30 automatically into the opening 31, in which position the detent 30 will rigidly support the standard 11 in extended position with respect to the disc 14.
The outer end portion 34 of the section 25 of the standard 11 is positioned between the oppositely disposed elongated plates 35. These plates 35 are of similar size and shape.
The corresponding lower end portions of the plates 35 are connected to the end portion 34 by a wing nut bearing bolt 36. Between the end portion 34 of the section 25 and the corresponding end portions of the plates 35 are arranged brackets 37, which, together with the opposite corresponding end portions of the plates 35 are connected to the end portion 34 of the section 25 by a rivet 38. The brackets 37 have angled end portions 39. Mounted on these end portions 39 is a circular disc 40. Positioned on the disc 40 is an outer disc 41 spaced from the disc 40. Between these discs 40 and 41 are positioned the end portions 42 of pivoted arms 43, the end portions of which are angled upwardly to provide plastic-covered jaws 44 which bear against the instrument 45 being supported by the stand.
Positioned between the discs 40 and 41 is an elongated channel-shaped member 46. Slidable through this channel member in a direction longitudinally with respect to its long axis is the shank 47 of an arm 48, which, like the arms 43, has a plastic-covered jaw 49 adapted to cooperate with the jaws 44 to firmly hold therebetween the musical instrument 45. The arm 48 is yieldably restrained in its movement by a spring 50, one end of which is connected to the arm 48 and the opposite end to the brackets 37, as seen in FIG. 3.
The spring 50 functions normally to resist movement of the arm 48 relative to the channel member 46 and to yieldably urge the instrument 45 within the confines of the jaws 44 and 49. A stop pin 51 is carried by the for firmly holding the in and to hold the standard-11 substantially rigid during playing of theri nstrument. The simple form of detent permits the standard 11 to be readily col-lapsed with in minimum amount of effort, with respect tofthe legs 16 and 18. a The thumb nutbea-ring bolt36s may be adjusted to vary the tension at the pivotal connection of the head I2 with the end portion 34 of the section 25, so as. to firmly hold the head 12in an adjustedposition with respect to the standardll.
The arms 43, as'well as the legs 1 6, are free toswing about their respective supports, but will stay any position to which they are adjusted. The arm 48 beingv adjustable relative head 1240 support with firmness and rigidity a variety of sizes of musical.instruments.- By the use of the springcontrolled slidable arm 48, the musical instrument; may be quickly and easily rnounted upon and removed from thehead; V v 1 U,
