Claims.

This invention relates to a portable supporting stand which is capable of being extended to various lengths or heights, and which is so constructed that when not in use the parts thereof may be readily nested Within one part and effectively retained therein so that the stand may be conveniently carried or transported or stored.

More particularly, it is an aim of the invention to provide an irrigating stand adapted to be used by doctors and nurses and in hospitals for holding apparatus used in administering medical irrigations atvarious desired elevations.

Still a further aim of the invention is to provide a stand of the above described character having supporting legs, at the lower end thereof and which form a tripod for su porting the stand in an upright position, and which may be readily folded within a primary standard or post of the stand, when not in use. I

Still a further object of the invention is to provide an irrigating stand of simple construction that may be economically manufactured and sold and which will be durable and sturdy.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, which illustrate a preferred embodiment thereof, and

wherein:

Figure 1 is a side elevational view showing the supporting stand extended,

Figure 2 is a longitudinal substantially central sectional view, partly in elevation, showing the stand in a folded position,

Figure 3 is a longitudinal central vertical sectional view, partly in elevation, showing the stand extended, as in Figure 1,

Figure 4 is an enlarged fragmentary central vertical sectional view of a portion of the stand shown in Figure 3, and

Figures 5 and 6 are cross sectional views of portions of the stand, when in an extended position, and taken substantially along the planes indicated by the lines 5-5 and 6-6, respectively, of Figure 3.

Referring more particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout the different views, I0 designates generally the stand in its entirety, and which includes an elongated tubular member II having an externally threaded upper end I2 and an externally threaded lower end I3.

An elongated tubular member I4 telescopes into the end I2 of the member II, and is provided with diametrically opposed longitudinally extending slots I5, which extend from intermediate of the ends of the member I4 through its outer end. A pair of corresponding arms I6 extend inwardly through the inner ends of the slots I5 and, as best seen in Figure 6, have their inner ends disposed between shoulders I'I, within the member I4, and pivotally connected to the member I4 by means of pivot pins I8 which extend therethrough and through the shoulders I1. The arms [6, when in extended positions, are supported substantially at right angles to the member I4 by engagement with said member at the inner ends of the slots I5. The outer ends of the arms IB are provided with hooks or abutments I9. The arms I6 may be swung upwardly from their positions, as seen in Figures 1 and 3, through the slots I5 for positioning the arms I6 in the upper or outer end of the member I4, and with the hooks or abutments I9 disposed beyond the outer end thereof, as seen in Figure 2. The upper end I2 of the member II is provided with an inwardly extending annular internally threaded portion 20 and the outer or upper end of the member I4 is provided with an outwardly projecting collar 2| which is adapted to rest on the portion 20, as seen in Figure 2, when the inner member I4 is in a retracted position to limit the movement of the member I4 inwardly of the member II. The opposite, inner end of the member I4 is provided with an externally threaded collar 22 which can be connected to the portion 20 for holding the member I4 in an extended position, by turning the member I4 relatively to the member I I after it is in substantially an extended position. It will likewise be readily obvious that by continuing to revolve the member I4 that it can be'detached from the member II but that when the member I4 is slidably engaging the member II it cannot be slid out of engagement therewith without revolving it.

A cap 23 is internally threaded to engage the threaded end I2 and is provided with an opening 24 in the top thereof through which the member I4 is slidable. Cap 23 is provided with inwardly extending set screws 25 which can be advanced to hold the member I4 in a partially extended position, or which can be advanced to engagethe shoulder 2I for holding the member I4 in aretracted position.

The lower end I3 is provided with three slots or elongated openings 26 which extend through the end thereof and which are equally spaced from one another circumferentially. The member II is provided with three longitudinally extending enlargements 21 on the outer side thereof which are disposed in alinement with the slots 26 ly disposed in each of the grooves 32 and is pivotally connected to the collar 3| by means of a pivot pin 34. The pivot pins 34 extend through the grooves 32 and have their ends anchored in the collar 3|. It will thus be readily apparent that the legs 33 can be folded against the rod 29 or extended relatively thereto to project outwardly therefrom. Also, the pivoted ends ofthe legs 33 can be adjustably positioned relatively to the rod 29 by turning the collar SI for longitudinally adjusting it relatively to the rod. A nut 35 is mounted on the threaded portion 39 and engages the lower end of the collar SI for holding it against movement in a direction out of engagement with the rod 29. Two nuts 33 are mounted at the outer end of the threaded portion 30 and in spaced apart relationship to one another, and a collar or washer 3? is turnably mounted and loosely disposed on the threaded portion 39 and between the nuts 39, and is adjustably positioned relatively to the rod 29 by means of the nuts 33. The washer or collar 31 is provided with an upwardly projecting annular externally threaded flange 38 to which one end of an inter- 29 in position in the lower end of the member I I.

From the foregoing it will be readily obvious that the legs 33 can be arranged to project outwardly through the slots 26 and the sleeve 39 can be attached to the end I3 and advanced relatively thereto by being turned with the washer or collar 31 so that the upper end of the sleeve 39, as seen in Figure 3, will engage against the legs 33 for holding each leg flush against a beveled end 28 so that the three legs 33 will be disposed at the same angle to the longitudinal axis of the member II and so that said legs will project outwardly and downwardly therefrom to form a tripod which is adapted to rest on a suitable sup: porting surface for supporting the tubular members I I and I4 in substantially upright positions. When the stand I0 is thus supported on the legs 33 the member I4 can be extended to any desired extent and retained by the set screws 25 or the threaded portions 20 and 22, as previously described, for positioning the supporting arms I6 at any desired elevation. It will be obvious that the supporting arms I6 are adapted to support any apparatus used in the administering of a medical irrigation or may be used for any other desired purpose, and their hook portions or abutments I 9 will prevent such apparatus, not shown, from sliding oif of the outer ends of the arms.

When the stand I0 is not in use the tubular member I4 may be nested in the upper end of the tubular member II, as previously described and illustrated in Figure 2. Also, the sleeve 39 may be unscrewed from the threaded end I3 so that the rod 29 and legs 33 can be detached from the member II after which the legs 33 can be folded against the upper end of the rod 29 and inserted into the lower end of the member II so as to nest therein and be retained by the sleeve 39 being again engaged with the threaded end I3, as illustrated in Figure 2. It will thus be readily apparent that when the parts are nested, as seen in Figure 2, that the stand I0 can be stored in a very restricted space or readily transported or carried.

Various modifications and changes in the invention as disclosed are contemplated and may obviously be resorted to, provided they fall within the spirit and scope of the invention as hereinafter defined by the appended claims, as only a preferred embodiment of the invention has been illustrated and described.

I claim as my invention:
