Oct. 25, 1960 L. RAlA TELESCOPIC STAND Filed June 6, 1958 WIIIIIIIIIIIIIII IELESCOPIC STAND Louis Raia, Chicago, Ill., assignor to Wiimette Screw Products, Wilmette, lll., a partnership of Illinois Filed June 6, 1958, Ser. No. 740,380

1 Claim. (Cl. 5 317) The present invention relates broadly to telescopic stand structures, and is more particularly concerned with `a. stand of the collapsible type particularly well adapted for use in hospitals and the like.

Stand constructions heretofore proposed for the elevated support of intravenous solution bottles are characterized by a number of objections and disadvantages. First, the floor or pedestal type is relatively weighty and cumbersome, and the movement thereof from one location to another by nurses presents fatigue problems. In addition, the floor supported stand utilizes much needed space in the hospital room, and constitutes an interference to the free movement of persons in the room. Storage problems also arise, and in the case of a known collapsible stand wherein adjustment of a solid rod within a tube is accomplished by a thumb screw, the mentioned disadvantages of substantial weight and difficulty of storage subsist.

It is therefore an important aim of the present invention to provide a telescopic stand construction partieularly well adapted for medical use and which may readily be carried by a nurse on the medicine tray or stored in a bedside cabinet.

Another object of this invention is to provide a collapsible stand supportable by the bed end and formed of a plurality of tubular sections receivable one within the other upon depression of a single `resiliently urged catch member.

Another object of the present invention lies in the provision of a telescoping stand constructed of low cost and light weight tubular sections formable at minimum cost upon automatic screw machines.

A further object of this invention is to provide a collapsible stand construction comprised of tubular sections wherein bearing contact during slidable movement of one section within another section is obtained without resort to a close diameter tit between the collapsible sections.

Other objects and advantages of the invention will become more apparent during the course of the following description, particularly when taken in connection with the accompanying drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure l is a view illustrating the stand of this invention typically mounted upon a bed end;

Figures 2 and 3 are side elevational views of the present ystand in collapsed and extended positions, respectively;

Figures 4, 5 and 6 are vertical sectional views taken substantially along the lines IV-IV, V-V and VI-VI, respectively of Figure 3; and

Figure 7 is a detail sectional view of portions of the tubular sections during the collapse thereof.

Briefly stated, the novel stand of this invention comprises a plurality of tubular sections of different outer diameters cut into predetermined lengths from standard tubular stock. One end of the larger tubular section has a stud staked therein for location of the stand in an opening in a 4bed end or in a clamp attached to the bed arent f end, while at one end of the smallest tubular section a head portion is provided mounting hooks or the like for receiving the bails of intravenous solution bottles or other medicaments. Each of the tubular sections receiving lesser diameter sections is provided at spaced locations along its length with bearing surfaces preferably formed by indenting the walls thereof providing beads along their inner diameters subsequently reamed to a flat conguration to provide the bearing surfaces. Spring pressed button means prevent inadvertent collapse of the tubular sections, and one end of each of the inner tubular sections is ared outwardly to engage the bearing surfaces to thereby limit the extension of the sections with respect to one another. Additional structural features of the stand of this invention will become more apparent during the course of the description now to follow.

Referring now to the drawings, `a stand designated generally by the numeral 10 is shown -in Figure 1 in an installed position of use upon a bed 11 of the type employed in hospitals and other institutions. The bed is provided with an end section 12 having a horizontal rail portion 13 provided with openings or holes 14 therein receiving the stand 10 and maintaining the same in an essentially vertical or Iupright position. Clamp devices of various types may also be used to mount a stand of this invention in a position to support at an elevated level an intravenous `solution bottle 15 or such other containers as are customarily maintained upwardly of a patients bed. While a particularly successful application of the teachings of this invention has been in the support of intravenous solution bottles, it will be appreciated that a stand 10 of the character herein disclosed is not limited to medical applications and various other uses exist therefor.

In the exemplary form shown, the stand 10 comprises three tubular sections 16, 17 and 1S, although a lesser or greater number of such hollow sections may be employed to meet particular requirements. The sections are cut to the desired length from standard tubular stock, the material preferably being anodized aluminum. By provision of the bearing surfaces to lbe later described wide tolerances are permitted in the concentricity of the tubular sections and accordingly substantial economies characterize the manufacture of the stand of this invention.

The base or largest diameter -section 16 carries at one end a stud 19 ffor supporting the stand 10 in a bed end opening 14 in the manner of Figure l. The stud 19 is preferably of solid construction and is staked at 2t? to the base section 16. For this pur-pose the stud 19 is provided with a generally conical groove 21 adjacent one end and said end may be knurled as at 22 in order to more firmly maintain the stud within the tubular section 16. An important advantage of the present invention is that substantially the entire stand 10 may be fabricated upon an automatic screw machine at substantial economies. It is for this reason that staking is the preferred method of anchoring the stud 19 within the tubular section 16; however, it `will readily be apparent that screws or other means may be employed.

The opposite end of the tubular section 16 mounts the section 17 when the stand is in the extended position of Figure 3. Bearing contact between the intermediate section 17 and base section 16, both when the stand is in collapsed or extended form, is obtained by provision of axially spaced bearing surfaces 22 and 23 adjacent the end of the section 16 mounting the section 17. It is to be noted that the bearing surfaces 22 and 23 are essentially flat along the inner diameter of the tubular section 16, and said surfaces are formed by indenting the other diameter of the section 16 to form generally V-sha-ped grooves 24 and v25 providing initially a generally rounded bead at spaced locations along the inner diameter, which are subsequently attened by a relatively simple reaming operation. It is therefore now apparent that variations in the concentricity of the tubular sections can well be tolerated without interference to movement of the tubular sections and the outer diameters of said,V sections can also vary without loss of proper functioning of the stand 10. Y

One end of the intermediate tubular section 17 is ared outwardly as at 26 (Figure 5) and said ared end is in engagement with the bearing surface 23 when the tubular section 17 is extended with respect to the tubular section 16. The bearing surface 23 accordingly performs a dual function, being in contact with the outer diameter of the tubular section 17 during slidable movement and l Vextension of the stand, as well as providing an abutting surface contacting the ared end 26 of the section 17.

The opposite end of the tubular section 17 mounts the smallest diameter or top tubular section 18, and the formation of bearing surfaces or ribs on the section 17 is substantially identical to that earlier described in connection withV tubular section 16.V The suffix a has accordingly been appended to the numerals 22-25 designating th'ebearingY surfaces or ribs and grooves upon the tubular section 17.

YCarried at the opposite end of the smallest diameter section 18 is aV cap portion designated generally by the numeral 27. VAs appears in Figure 4, the cap portion comprises a stem 28- receivable within the tubular section 18 and provided with a generally conical groove 29 for staking the tubular section 18 to the cap portion 27 as at 38. The cap portion further includes a generally cylindrical head 31 of substantially greater diameter than the tube 18 and stem 28 of the cap portion 27, and against a face 32 of the head 31 the tubular section 18 abuts as at 33. At diametrally opposed locations upon the head 31 there is provided hooks 34 and 35 attached to the head 31 by rivets, screws or the like 36. The hooks 34 and 35 provide support for a bail or similar means 37 mounting the bottle 15 in the manner of Figure l.

To prevent inadvertent telescoping or collapse of the' l stand 1t) when in the extended position of Figures l and 3, there is provided the spring pressed means shown in Figures 5 and 7. Said means form a part of each of the sections 17 and 18, and like numerals have been employed to designate the parts thereof, the subscript a `designating corresponding parts of the spring means on the tubular-*section 18. The spring pressed means comprise in a-preferred form a generally dome-shaped button 38 having a radially outwardly extending flange 39 resiliently urged against the inner diameter of the section 17 1 by a hairpin spring 40. Said spring includes a transverse leg 41 receivable within the button 38 and generally axially extending connected legs 42 and 43, the latter being in springable contact vwith the inner diameterV of either of the sections 17 or 18. Other spring constructions may, ofcourse, be-employed to fuliill a more specic need.

A feature of this invention lies in the ease with which the tubular sections 16, 17 and 18 may be collapsed to form the relatively small length structure of Figure 2.

To collapse the sections, the button 38 on the tubular section '17, is pressed radially inwardly to permit the sec-V tion 17 to slide axially within the section 16. The tubular section 18 is then also moved axially, and referring now particularly to'FigureV 7, it may be seen that the button 38a bears againstpa tapered end wall 44 on the4 base secameter section 18 within the tubular section 17. Thus,

to collapse the stand 10, only the button 38 on the intermediate section 17 need be depressed in order to entirely collapse the stand into the form of Figure 2.

It may be seen 'from the foregoing that applicant has provided a new and improved collapsible stand construction featuring a minimum number of readily fabricated and assembled parts. Eachf'of the tubular sections may be formed on an automatic screw machine at substantial economies, and by provision of the bearing surfaces disclosed, standard stock tube of varying outer diameters may be utilized at additional economies. The stand may be quickly collapsed, and'it'is now possible to transport a hospital-type stand upon the nurses medicine tray and to store the same in a bedside cabinet. V 1

lt is to be understood that the lform of the invention herein shown and describedV is to be taken as the preferred embodiment ofthe V`same',`and that various changes in the size, shape.. and arrangement Vof parts may be etected without departing from the spirit of the invention or the scope of the subjoined claim.
