The Vprincipalobje'cts ofthis invention are to provide a means of supporting a lamp from abed frame in such a mannerthat it may be' readily adjusted 'to various positions and held'A sjsecurely in theadjusted position in a-simple and effective manner sothat itcannotf'be accident'ally dislodged but so'arranged that it may beeasily and quickly moved out of Ithe way withoutbeing removed from it-ssup'- lowport. f
'A further and very `important vobject is toV provide a support which may be extended to 1 an extraordinary distance, either vertically or horizontally to facilitate its use particu- "larly for hospital purposes and further to provide a support which may be readily utilized for the support of utensils required in hospital service. i
The principal features of the invention -consist in the novel arrangement of an upright guide upon a bed frame whereby a supporting member is adjustably mounted and the adjustable member is capable of universal movement to support a lamp in a raised or "horizontally extended position.
In the accompanying drawings Figure 1 is an elevational view of the end frame of a bed illustrating the preferred form of application of the invention as applied to a lamp support.
Figure 2 is a side elevational View of Figure 1.
Figure 3 is a side elevational view showing the lamp support extended in a horizontal position.
Figure 4 is an enlarged longitudinal sectional detail of a portion of the extensible lamp supporting post.
Figure 5 is an enlarged perspective detail 'showing the hinge joint of the extensible post and the means for locking the post in adjusted positions.
Figure 6 is a perspective detail of a. support member to be used in the tubular lamp 4arm support.
In the form of the invention herein shown the end frame 1 of the bed is of the usual type of tubular structure having a plurality of `vertical tubes 2 extending downwardly from the horizontal top portion 3 to a cross tube 4.
One of the vertical tubes 5 extends through the top of the top tube 3 and has secured to its upperL end or forming part thereof a longitudinally slotted chuck member 6, provided with a'threaded portion 7. f
Achuck sleeve 8 threaded on to the portion 7 is` provided with a tapered inner wall 9 to engage Lthe tapered surface of the slotted chuck member. This sleeve is provided with a suitable head end 10 which enables it to be ed. readilyjgrasped by the hand for tightening or loosening.
The lower end of the tube 5 may extend below the cross tube 4 if such length is desired.
-A long tube or rod 11 is slidably arranged 65 Within the tube 5 and extends through the top of the chuck sleeve. This tube is provided adjacent to its lower end with a hinge joint 12 which allows the major portion of ,the length of the tube to be bent into right 7() angular position in relation to the tube 5 to extend horizontall and the joint is so made that the extension portion rests in a horizontal position. A
The upper end of the tube 11 has secured 75 therein a length of fibre rod 13 which forms an insulating connection to the tubular member 14 to which is secured a flexible lampsupporting arm 15.
The member 14 is provided with a hollow 8()V lateral extension 16 through which the electric wires 17 are connected to the lamp socket.
A suitable shade 18 is provided 0n the end of the flexible arm to enclose the lamp.
It will be seen that when the lamp-sup- S5- porting tube l1 is in the vertical osition illustrated in Figures 1 and 2 the flexible arm 15 may be bent into any desirable position to throw-the light from the lamp downwardly and the arm may be swung horizontally 901' by allowing the tube 11 to rotate in its support;` It may, however, be fastened securely inany desired position by tightening the chuck sleeve 8`so that the slotted chuck member will grip and hold the tube.
If it is desired to raise the lamp, this may be'done vby loosening the chuck sleeve and simply pulling upwardly upon the tube 11 and then a slight turn of the chuck sleeve will hold it.
- examination is to be made, thelalnp Vsupport tube.y llmay be raised upwardly v,until sleeve, when it may then be swung to ahorf izontal position as illustrated in Figure 3 and the horizontally extending'` membermayfbe locked securely or swung from side to side pivoting in the support 2 and the flexible' lamp armV on the endvofthis-ntube enables the adjustment of the light to any desired position over thev patient.v .f-
