Description

May 14, 1963 o. BLOMQVIST 3,089,692
MEDICAL TIPPING TABLES Filed. April 5, 1961 ATTORNEK? United States Patent Orifice 3,089,692 patented May 14, 1963 3,089,692 MEDICAL TTPE'ING TABLES Olle Blomqvist, Artillerigatan 38, Stockholm, Sweden Filed Apr. 3, 1961, Ser. No. 100,423 ll Claim. (631. 269-323) This invention relates to medical tipping tables of the kind having a top or resting table which is adapted to support a patient and is tippable or rotatable from a substantially horizontal position to a substantially vertical position, a frame-work in which said top is arranged, at least one spring unit, one end of which is secured to the top of the table and the another end of which is secured to the frame-work, being adapted to counter-balance the moment arising when tipping or turning the top of the table and a patient resting thereon around said axis. Such tables are primarily used for raising patients, that is for transferring a patient lying in a bed from horizontal position to vertical position standing on the floor.
The main object of the invention is to provide a simple and inexpensive medical tipping table of the above-mentioned kind which may be manually swung or tipped with a minimum of effort.
With this and other objects in view the spring unit of the tipping table according to the invention comprises at least one compression spring which is compressed when the top of the table is in its substantially horizontally position and is attached to the top of the table and the frame-work at points located on the same side as the centre of the top of the table with respect to a vertical plane through the pivot axis of the top of the table during normal use of said tipping table.
Further objects and advantages of the invention will become more fully apparent from the following description and the accompanying drawing illustrating one preferred embodiment of the invention, and in which:
The single FIGURE is a side elevation of the medical tipping table according to the invention.
The medical tipping table according to the invention comprises a frame-work 1, a spring unit 2, a resting table 3 provided with a foot-plate 4. The resting table or top of the table 3 is shown in full lines in its horizontal position and in dash-dot lines in its somewhat inclined but substantially vertical position of equilibrium, a patient resting on the table being also represented in dash-dot lines in the latter position of the top of the table 3'. In this position the centre of gravity 6 of the combined load consisting of the top of the table 3, the foot plate 4 and the patient is located in the same vertical plane as the axis of rotation 5 of the top of the table. The spring unit may be comprised of two telescopic tubes 7, 8 which have closed outer ends and are pivotally secured to the framework 1 and the top of the table 3 respectively. A compression spring 9 is arranged Within the telescopic tubes 7 and 8 and has its ends abutting against the closed ends of the tubes 7 and 8 respectively. Alternatively the spring unit may comprise any suitable number of compression springs and telescopic tubes. The upper telescopic tube 8 is provided with a suitable locking device by means of which the top of the table 3 and a patient resting thereon may be held in the position desired, eg in the horizontal position. When the top of the table 3 and the patient resting thereon is in the somewhat inclined but substantially vertical position of equilibrium represented in dash-dot lines, the compression spring 9 is in its state of equilibrium, that is neither compressed, nor expanded. When the top of the table 3 and the patient is swung downwards (counter-clockwise) towards the ground plane, the centre of gravity 6 of the patient and the top of the table 3 and its foot plate 4 is successively displaced from the vertical plane through the axis of rotation 5, whereby the moment tending to lower the head end of the top of the table 3 is progressively increased, at the same time as the compression spring 9 located in the telescopic tubes 7, S becomes more and more compressed. The more the top of the table 3 is rotated, the more the spring 9 is compressed and the more the force thereof counter-balancing the swinging movement is increased. By adjusting the length and the compression force of the spring in such a way, that said force, which varies (increases) from the position of equilibrium to the horizontal position, approximately eliminates or counter-balances the tipping movement as completely as possible the tipping table 3 may be raised or lowered at will with a minimum of effort to the position desired and then blocked in this position by means of the locking device 10. If the top of the table 3 should be swung clock-wise more than illustrated by dash-dot lines in the drawing, the spring 9 should tend to pull back the top of the table to its inclined position represented. This means that the equilibrium of the tipping table is stable.
While the invention has been particularly shown and described with reference to one preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
What I claim is:
An elongated, medical tilting table comprising a top which is adapted to support a patient and is tiltable from a substantially vertical position to a substantially horizontal position on a pivot axis substantially perpendicular to the longitudinal direction of the tilting table and located between one end of the top of the tilting table and the center thereof; a footplate united with said end of the tilting table and projecting therefrom; a framework carrying said top of the table; and at least one spring unit adapted to counterbalance moments arising when tilting the top of the table and the patient resting thereon on said axis and comprising at least one compression spring which is substantially relaxed when said top is in its substantially vertical position and compressed when said top of the table is in its substantially horizontal position, one end of said spring unit being hingedly secured to said framework in a first junction point located at the same side of said pivot axis as the center of said top of the table, the other end of said spring unit being hingedly secured to said top of the table in a second junction point located between said pivot axis and said first junction for any tilting angle of said top of the table, the ratio of the spacings between said junction points when said top is in its horizontal and vertical positions respectively being greater than 1/2.
