EXTENSIBLE LEG- 1 Appliatin fue@ oetoter'zz,
Other objects and advantages of theV invention will be understood by lreference to the following specification andaccompanying drawings in which I have illustrated an ex@ tensible leg embodying the features of my invention'as applied to a bedstead, three selected forms of the invention `being shown.
In the drawings: Y v i Fig. 1 is-an end elevation ofa bedstead 2 is an .axial section through one` of lthe legs of the bedstead on an enlarged scale.
Fig. 3 is a section onthe line 3-3 of Fig.
Figs. 4 and 5 are perspectives of certain Y parts of the extensible leg structure.
Fig. 6 is an axial section similar to Fig. 2, but showing another form'of extensiblejleg made according to my invention. j k
Fig. 7 is an axial section of the leg shown in Fig. 6 through a planeextending `atright, angles to the plane of the section of Fig. 6, the inner stem portion being shown in elevation.
Fig. 8 is a section on the lineS-S of Fig.` 6.
F ig..9 is an axial section through 4an ex-v tensible leg embodying vanother selected form -of my invention.'
Fig. 10 is an axial section of the leg shown in Fig. 9, but extending through a plane at right angles to the plane of the section of Fig. 11 is a section on the line 11-11 of Fig.r9.
Referring now to the drawings, have `dicated a conventional form of end frame 10 fora hospital bedstead, which includes a top -rail 1-1, preferablyof tubular metal, and leg walls.

A suitable bed spring indicated gen`- erally at `16 may be a mattress. Y, rllhe legs 12 and 13, beingoftubularl metal,
provided for supporting are hollow and` receivestem members 17,`
which telescopel into the lowerend portions 18 of thelegs, which end portions may con-v venientlyv be referred toas sleeves.
In the embodiment shown in Figures 1 to 5 inclusive, the tubular frame parthas been shown as a rectangular, preferably square ings or notches 23, 23which are undercut so as tol provideseats 24, 24inthe said sidel A. plurality of suchvopenings and seats spaced longitudinally along the stem 7o f `member. Thestem 1,7 in this instance is formed of a channel member19, as clearly shown in Figures 3 and 1, and is provided at Y are preferably provided, as .clearlyshown 7 in `Figures 2 and 4. Y g For positioning the channel-shaped stem is, for limiting telescopingof the stem- `into -the sleeve, I provide a link-like member 25 .which is of such dimensionsthat it will embraceor {itaround the stem soas to-be free- .ly slidable longitudinally thereof but locked thereto ,againstI separation therefrom in a lateral direction. `'lhe'niember 25 Vincludes a bar or rod `portion-26` which is adapted to be seated on the seats24, y24, as clearly shown .19 longitudinally'of the leg or sleeve 18, that i l i sleeve is thus limited according to the position of the member 25 with respect to the stem'. vThe ends of the bar part 26 are bent rearwardly, and said rearwardly bent portions prevent endwise movement of the bar Vout of operative position in the seats 24, 24,
and the end portions of the rearwardly bent Vparts, are in turn bent towards each other sleeve'18 and the bar part 26. of the member 25, serves to prevent such-upward movement of the locking member so that accidental displacement or unseating of the same is not likely to occur. The entrance to the openings or notches 23 is also closed by the lower end portion 27 of the sleeve member, as clearly shown in Figure 2. When it is desired to adjust the height of the leg, the article of furniture mustbe lifted sufficiently to take the weight thereof otl of the member 25 and to openthe entrance to the notches or recesses 23. -The locking member 25 may then be swung into a substantially horizontal vposition, as indicated in dotted lines at 28 in Figures 2 and 3, after which the same may be moved upwardly and laterally of the stem to unseat the said locking member. To extend the leg, it is only necessary to lift the article to a position slightly higher than the desired height to permit the locking member to be seated in the proper seats, after which the article may be lowered sol as to Acause its weight to be supported by `the locking member in the manner above described and so that the locking member is itself locked inoperative position. V
In Figures 6, 7 and 8, I have shown an extensible leg made up of substantially roundV tubular metal parts. In this embodiment, the leg'member proper or sleeve is indicated at i 18ZL and the stem at 19a, as clearly shown in Figure 8. These parts are round tubular members, the stem partbeing of such di- Y ameter that it slidably lits or telescopes into the sleeve part 18a. Seats 24@ are provided in the stem part 19a by notching or recessing the' same,fas clearly shown at 23a. The notches or recesses 23e are undercut, as shown, so that pairs of seats are formed which correspond to the pairs of seats formed in the square leg structure hereinbeijfore described. A more or less linkeshaped locking member 25a having a straight bar portion 26EL is adapted to--be seated selectively on the seats 24a and to support the sleeve 18a by receiving its lower end, as clearly shown inFigure 6.
`The outer, end of the member 25a is preferably rounded, as clearly shown in Figure 8,V y
so as to fit closely around the stem whereby the member will not form an objectionable projection on the stem. kA suitable Vcaster 22a` is swiveled in the lower end of the stem 19, a socket element 2()a being secured in the lower end of the stem in any suitable manner.
In Figures 9, l10 and 11, I have shown a modified form oli-locking device applied to a round tubular metal leg structure which includes a lcg'proper or sleeve 18b and a round tubular metal stem 19b which telescopes within the sleeve 185. y A, caster 22b is swiveled in the `lower' endjof vthe' stem 19b through the agency of a socket member 2()b which is secured inthe lower end ofthesaidfstem in any lsuitable manner. Y
For locking the stem part 19b in the desired position of extension, I provide a locking member 29 in the form of a linkthe same being provided with an inwardly-extending projection or toothl 30 which is adapted lto enter into any one of afplurality ofapertures 32* inthe stem 19? and spaced longitudinally thereof. The inwardly-projecting tooth 30 is i preferably oiiset downwardly, as indicatedin Figure 9. The tooth 30 is effective to position the locking member 29 at the desired location along the length of the stem 19b and is adapted to support the sleeve, as clearly shown in the figures. i Y@ The angular arrangement of the tooth 30 is such thatfwhen the member 29 is moved from its operative position, as shown in Figure 9, in a direction todisengage the tooth from the aperture, the member will be caused to move upwardly a certain amount. Since the weight of the supported article is directly applied to the member 29, such upward movement is resisted by such weight and the locking member thereby effectively locked against accidental unseating.
The above-describedV extensible leg struc-V strued as broadly as possible consistent with the state of the art.
I claim as my invention: v f
