Definitions

• This invention pertains to the field of medical care products. More particularly, it pertains to medical hardware and, specifically, a hanger assembly for an upright pole upon which is hung various medical devices such as intravenous bags, blood monitors, nurse identification devices and blood pressure equipment. Description of the Prior Art
• This invention comprises a hanger assembly for an upright support hardware pole that is foldable to a small configuration for ease in transport and storage.
• the traditional long, heavy hanger arm has been changed to an articulated radial arm capable of being locked into
• the folded hanger assembly allows the visiting nurse or home owner to easily load and transport a plurality of these devices in a passenger vehicle, where such would not be the case with
• This invention comprises a plug for attachment to the top or upper portion of the support pole, a cross-arm extending horizontally therefrom, a hanger arm pivotally- connected to the cross-arm and containing means for 2 Q hanging medical equipment therefrom, and means for locking the cross-arm and hanger arm into mutual horizontal axial alignment during use with medical equipment and thereafter unlocking the hanger arm to permit it to be folded into a storage position adjacent or parallel to the support pole.
• the invention comprises a hanger 'assembly for an upright equipment pole including: means for attaching the hanger assemly to the equipment pole; a cross-arm extending from the attaching means and terminating at a terminal end spaced apart from the pole; at least one 3 hanger arm having first and second ends , the first end mating with the terminal end of the cross-arm in at least one configuration of the hanger assembly, with the hanger arm comprising means for hanging equipment therefrom; and means proximate to the first end for locking the cross-arm 5 and hanger arm into an operational configuration such that equipment may be hung therefrom, and thereafter unlocking the arms to permit the hanger arm to be swung into a storage configuration.
• our object of this invention is to provide a hanger assembly for an upright medical equipment-
• a hanger assembly that contains a convenient means of hanging an intravenous bag therefrom; a hanger assembly that is easily, quickly and conveniently foldable to a 1 Q storage configuration and unfoldable into a working configuration merely by pulling the hanger arm out of axially aligned receipt in a bore formed in the end of the cross-arm; a hanger assembly that is retrofittable to virtually every medical equipment support pole in
• Figure 1 is a side plan view, partially in section, of one embodiment of the hanger assembly of this invention shown mounted to a typical medical equipment support pole.
• Figure 2 is a side plan view of the exterior of the 3Q sleeve that comprises part of the locking mechanism.
• Figure 3 is the same view as in Figure 2, except that the sleeve and the associated arm ends are rotated through 90 degrees.
• Figure 4 is a sectional side view of the embodiment 2 shown in Figure 2 taken along lines' 4-4 therein.
• Figure 5 is a partially sectional view of the same embodiment shown in Figure 4, except that the arms are unlocked and rotated into storage position.
• Plug 3 for attachment to the top end of a typical hollow aluminum or stainless steel medical equipment support pole 5.
• Plug 3 includes a male portion 7 for insertion into hollow pole 5, or for direct attachment should pole 5 be of- the solid variety.
• Male portion 7 is attached to pole 5 by any convenient means including welding, glueing or threading as is known in the art.
• a female portion 9 extends up from male portion 7 and includes a cross-bore 11 formed therethrough.
• a cross-arm 13 is received in cross-bore 11 and, as shown, comprises a solid rod extending completely therethrough to terminate at a pair of opposed ends 15 and 17, both spaced apart from pole 5.
• Gross-arm 13 can merely extend horizontally in one direction only so that terminal end 15 would be spaced apart from pole 5 and terminal end 17 housed or carried in cross-bore 11. This modification is fully contemplated within the scope of this invention.
• a hanger arm 19 having first and second ends 21 and 23, respectively, is shown, wherein first end 21 is adapted to contact cross-arm end 15 for locked axial alignment and unlocked storage configuration as explained hereinafter. Where cross-arm 13 passes completely through cross-bore 11, a second hanger arm 19 will be connected to end 17, as shown in Figure 1. For clarity purposes, only one hanger arm assembly will be described, all others being of the same or similar geometry.
• means 25 for hanging medical equipment therefrom.
• means 25 comprises a loop 27 bent or formed in hanger arm 19, wherein the terminal end 23 extends in an upwardly direction when said hanger arm 19 is positioned in its horizontal, medical equipment support geometry.
• hanger arm second end 23 is spaced slightly apart from the center straight portion of hanger arm 19 so that medical equipment, such as an intravenous bag, having an end support tab containing an aperture therein, may be conveniently hung from loop 27 by placing the hanging aperture over second end 23 and rotating the bag so that it hangs vertically downward from loop 27.
• means 29 Positioned adjacent hanger arm first end 21 is means 29 for locking cross-arm 13 and hanger arm 19 into mutual axial alignment, as shown on the left side of Figure 1, and thereafter unlocking to permit hanger arm 19 to be swung downward into storage position adjacent or parallel to pole 5, as is shown on the right side of Figure 1.
• Means 29 generally comprises a sleeve 31 slidingly disposed on one of said arms, either cross-arm 13 or hanger arm 19, and pivotally-connected to he other of said arms, either hanger arm 19 or cross-arm 13 across the contact point between cross-arm end 15 and hanger arm first end 21.
• sleeve 31 is slidingly disposed over hanger arm 19 and has an inwardly turned end terminating in an aperture 35 through which hanger arm 19 may move in reciprocal motion.
• Sleeve 31 is hingedly-connected to cross-arm end 15 by a pair of axially aligned short hinge pins 37a and 37b that are received in a pair of mutually opposed ears 39a and 39b extending from the opposite end of sleeve 31.
• An axial bore 41 is formed in cross-arm end 15 and spans the distance between hinge pins 37a and 37b and is of a size and shape adapted to receive hanger arm first end 21 therein.
• a coil spring 43 is disposed over hanger arm 19 and compressed between inwardly tapered end or stop 33 and a second stop or collar 45 affixed to hanger arm 19 and secured thereto by a snap ring 47 mounted in a groove 49 for ed circumferentially thereabout.
• hanger arm 19 and hanger arm first end 21 urges hanger arm 19 and hanger arm first end 21 into receipt within bore 41 to lock cross-arm 13 and hanger arm 19 in axial alignment. Penetration of hanger arm first end 21 into bore 41 is limited by snap ring 45 coming into abutment with cross-arm end 15 (see Figure 4). As shown in Figure 5, hanger arm 19 may be unlocked from axial alignment with cross-arm 13 by pulling outward on hanger arm 19 to overcome the compression bias of coil spring 43 and withdraw hanger arm first end 21 from bore 41. Thereafter, hanger arm 19 and sleeve 31 may be rotated through an angle such as 90 degrees to place them parallel to pole 5 for storage and transfer purposes.
