MUSIC STANDS Filed Sept. 15, 1958 FIG. 1
IN VENTOR. i HARRYZ WENGER A 'r TORNE Ks 3,004,743 MUSIC STANDS Harry J. Wenger, Owatonna, Minn. Filed Sept. 15, 1958, Ser. No. 7 60,981 2 Claims. (Cl. 248-161) This invention relates to new and useful improvements in music stands such as commonly utilized by the members of an orchestra orband, and by the director of the group. Such stands are usually made vertically adjustable so that they may be adjusted to support the music at the desired elevation for each individual player or musician.
There are now available on the market music stands comprising an upright st'andard composed of a pair of telescopic members, one of which is axially movable in the other to permit vertical adjustment of the usual music rack of the stand. Such stands as now commonly constructed are usually provided with one or more screws or threaded elements for securing the movable telescopic member in adjusted position in the fixed telescopic member. Such screws or securing elements must be normally operated when it is desired to raise or lower the music stand. Itmay also be necessary for the musician to use both hands when adjusting such a stand which, at times, may prove highly impractical.
, The present invention aims to provide a simple and inexpensive music stand comprising a novel and uniquely constructed securing means for securing the movable member of the supporting standard in adjusted position in the fixed member, and whereby the movable member may be readily slid from one position to another by the player or operator, by simply grasping it and moving it to the desired position. No separate tools are required to free the movable member from the relatively fixed member. v I
g A further object is to provide a vertically adjustable music stand, a composite supporting standard comprising a fixed lower member and a movable upper member, said members being disposed in axial alignment, and the upper member being slidable in the lower member to vertically adjust the rack secured to the upper end thereof, and means being provided within the fixed member for securing the movable member in adjusted position within the fixed member, such adjustment being readily effected by simply grasping'the movable member and manually pulling it upwardly, or forcing it downwardly in the fixed member, thereby to bring the music rack into alignment with the players eyes.
' A further and more important object is to provide a vertically adjustable music stand comprising inner and outer-tubular members telescopically connected together, one ofs aid members having its lower end'fixed to a suitable base, and the other :member having'its lower end portion slidably received in the fixed member, said fixed member having a non-metallic bushing secured in its upper end for guidingly supporting the inner member therein, and the lower end of said inner member having a non-metallic plug secured thereto having means for laterally. expanding it intofrictional engagement with the wallofthe-bore of the outer member, thereby to retain the movable member in fixed relation therein.
A further object of the invention resides in the specific construction of the plug provided in the lower end of the innermember, said plug being constructed of nylon and having a skirtdepending from its lower end and slightly flared outwardly in position to engage the wall of the bore of the outer member when the wall of said skirt is outwardly expanded, an expanding element being movably mounted within said skirt and constantly engaging said skirt with an expanding force thereby to force the nited States Patent wall of the skirt into frictional engagement with the wall of said fixed upright member, the frictional engagement between said plug and the fixed member being sufficient to adequately support the vertically slidable inner memher in any position within the fixed supporting member. Other objects of the invention reside in the specific construction of the nylon plug secured to the lower end of the inner member, and the means provided for radially expanding or contracting the depending skirt to permit sliding movement of the upper telescopic member within the lower fixed telescopic member to vertically adjust the music rack, as hereinbefore stated; and in an adjustable music stand, wherein the guide means for the inner tubular member and the bushing provided at the lower end thereof are made of nylon to provide ample wear and free sliding movement of the inner member within the outer fixed member. I These and other objects of the invention and the means for their attainment will be more apparent from the following description taken in connection with the accompanying drawings. I In the accompanying drawings there has been disclosed a structure designed to carry out the various objects-of the invention, but it is to be understood that the inven-i tion is not confined to the exact features shown, as vari-; ous changes may be made within the scope of the claims which follow.
In the drawings: FIGURE 1 is a view showing a sectional elevation of the lower portion of a music stand embodying my in vention; FIGURE 2 is a view showing the nylon plug detached from the inner tubular member to show the simple con-. struction thereof; FIGURE 3 is a view showing the expandable plug preferably used within the skirt of the nylon plug shown in FIGURE 2 to expand the walls of the skirt into frictional engagement with the wall of the lower fixed mem-' ber of the stand; movable member in vertically adjusted position therein; FIGURE 4 is a view showing a slightly modified con struction wherein a screw is utilized for expanding the skirt of the nylon plug; 7
FIGURE 5 is a cross-sectional view on the line 55 of FIGURE 4; and
IGURE 6 is a view showing a modified construction wherein a non-rigid plug is fixed in the lower end of the inner telescopic member and has a threaded hole therethrough for receiving a screw having its lower end portion traversing a resilient plug, which, when compressed in an axial direction by manipulation of said screw, is radially; expanded into frictional engagement with the wall of the fixed telescopic member, thereby to frictionally secure the inner member in adjusted position therein. The novel music stand herein disclosed is shown com prising a base 2 having a socket 3 therein which preferably is slightly tapered as shown for receiving the taperedterminal 4 of an upright tubular member 5. An anchor-5 ing plug 6 is shown fitted into the lower end of the tubular member 5, and has a screw 7 received in threaded engagement therewith which passes through an aperture 8 in the wall portion 9 of the base 2. The head 11 ofscrew 7 may seat against the bottom surface of wall portion 9. The anchoring plug 6, it will be noted, is tapered to fit the taper of the inner lower end of the tubular them her '5, whereby when screw 7 is manipulated to draw the plug downwardly, the plug will compress the tapered wall portion of the tubular member against the Wall of the tapered socket 3 in the base, thereby to firmly secure the upright member 5 in position in the base 2. The base may be provided with a plurality of radial extending arms.
Patented o r. 17, 1961 3 to add stability thereto and prevent the music stand from readily tipping over when accidentally engaged by an individual passing thereby.
.Slidably mounted within the fixed tubular member 5 a relatively smaller tubular member 13. Member13 is guiding'ly supported in the tubular member 5 by means of a bushing 14, fitted into the upper end ofmember 5, and a .plug 15 fitted into the lower end of the inner member13, as clearly illustrated in FIGURE 1.
.An important feature of the present invention resides in the construction of the bushing 14 andplug 15. These elements are Constructed of nylon, which is highly impervious to moisture, and provides an extremely smooth and hard wearing surface for the inner slidable member 13. The bushing 14 is pressed into the upper en'd of the tubular member 5, and its bore snugly fits the'periphery of the telescopic member 13, whereby said .member is freely slidable in member 5. p i
The nylon plug 15 secured to the lower end of the iitner member 13 has a portion 16 snugly fitted into the lower end of member 13. An annular groove 17.may be provided in the periphery of plug 15'into which aportion of the wall of member 13 may .be compressed, as indi- 'at'ed at 18 in FIGURE 1, thereby to prevent the plug from accidentally becoming detached from member 13.
The .plug 15, it will be noted, has a depending skirt 19, whichis vertically slit as indicated at 21 inFIGURES and 5, whereby the sections 22 between adjacent slits 21 may readily be pressed outwardlyinto frictional engagement with the wall of the lower fixed member 5 by manipulation of the expandable plug 23, generally designated by the numeral 23. l v
The expandable plug 23 is preferably constructed of a synthetic resilient material such as rubber, which is compressible axially to cause it toradially expand into engagement with the wall of the skirt 19,- as is shown in FIGURE 1. The plug 23 is axially apertured to receive a bolt or screw 24 having a nut .25 received in threaded engagement therewith. An enlarged washer .26 is shown seated against the opposite or bottom end of theplug 23, to be engaged by the head 27 of screw .24. Thus, when the nut 25 is tightened-on the screw 24, theplug 23 is compressed between the nut 25 and washer .26, which causes it to expand into engagement with the wall of skirt 19. v
The wall of the skirt is outwardly tapered from its upper end, and the exterior of the plug 23 is similarly tapered so that the plug may snugly fitinto the tapered socket defined by the skirt 19. The plug 23 is readily retained within the skirt by friction, and from actual experience .has shown it is not likely to become detached from theskirt 19. .Should the frictional engagement of the skirt 19 with the wall of the upright tubular member 5 become insufficient to retain the inner tubular member 13 in adjusted position, the plug 23 may be expanded by manipulation of the screw 24, thereby to expand the diameter of the plug 23 to force the skirt into frictional engagement with the wall of the fixed tubular member 5, as will be understood. Access to the screw 24 of the expansible plug 23 may be had by removal ofthe screw 7 from the bottom of the base. When this screw is removed, the aligned holes in the wall member 9 of the base and the plug 6 are exposed. A small screw driver may then be inserted through said aligned holes into engagement With'the slotted head 27 of screw 24, whereby the screw may readily be tightened to produce the necessary frictional contact between the skirt 19 and the wallof member 5, as will readily be understood by reference to FIGURE 1.
When the screw 7 is returned .to its normal position,- as'shown in FIGURE 1, the-screw head .27 in plug 23 is completely concealed and can .not be tampered with.
In FIGURE 4 there is shown a slightly modified construction wherein a screw 28 is received inthreaded engagement with the upper end of plug 15 and has an en'-' r a s he d 29 wi h. a 3 291.... .pc iph y w i fit against the inner surface of the tapered wall of the skirt 19. When the frictional engagement of ithe skirt with the member 5 is to be varied, the screw head 27 is rotated by the insertion of a screw driver thigpughithebottom of the base, as hereinbefore stated, wh 'eb'y thejfs'kirt may readily be expanded to the desired "degree, as will be readily understood. 1
In FIGURE 6 'tliereisillust'rateilanother modified construction, wherein .the non resilientplug 31; is secured in the lower end Q!- th t bu ar. mem e 133116 s a threaded bore therein rfor receivingthe threaded terminal of a screw 32. The .lower ,end portion of the screw traverses an'axialbore in Qa resilient pl ug 33 supported on the screw 32 between disks orwashers 34 and .35. The screw has a head 36 which may readily be manipulated by a conventional screw ,driver whercby the frictional e to t eph s 3. w thrthewa o th p t member 5 may readily be varied by ,relatively rotating the screwin the plug-31, will readily be understood when it is noted that by tightening the screw in plug 31, the resilient plug 33,is compressed-between disks 34 and 35, and thus is radially expanded into frictional engagement with the wall-of member 5, as will be. understood.
The usual rack or music supporting head of the upper end of the music stand is suitably pivoted to the upper end of member 13in the usual manneig and as it forms no part of the present invention, it has been omitted from thedrawing. p
The nylon bushing 14 an plug 15 haveproven extremely practical in the operation-of the music stand herein disclosed. The nylon skirted plug 15 at the lower end .of the inner telescopicunember13 makes it possible to so adjust the frictional contactbetween said plug and the wall of member 5,, that the upper telescopic member 5 may be supported-in any desired position in the fixed telescopic member 5 without the use :of separable locking elements, such as .screwsg ami the, ke. The nylon from which the bushing 14 and the plug 15 are made, wears extremely ,well, and has the inherent ability to maintain afree sliding contactbetween the parts, and with the assurance theupper memberl} is not likely to accidentally shiftiits position in member 5. N
In actual use, the frictional. engagement 'ofthe skirt of the plug 15 with the wall of the telescopic member 5 is so adjusted by manipulation of the expansible plug 23, that the upright movable member 13 will readily support all of the music tobe playedat a given concert by a single player. Inpther words, the frictional engagement of the skirt of the plug -15 isso adjusted that the weight of the sheet 'music for a full concert which is placed on the stand is not likely to capsethestand to shift or sag from itsoriginal position during a concert. A h sa m the use the qn sn e means o the inner member 13 permits said member to be readily slid up and downin the stationary member by simply grasping the member 13, asfwill be understood, I I The novel stand hereindisclosed also presents a very neat appearing deviccpf general type, as the upright has no projections, such .as lock screws, etc, usually found in most conventional stands of this general type. t The invention may beembodied in other specific forms without departing, from the essential characteristics thereof. Hence, the presentembodiments' are therefore to be consideredin all respects merely as beingillustrative and not as being restrictive, thescope of the invention'being' indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are there-= fore intended to be "embraced therein;
