Description
This invention relates to a doctor's examining table and
particularly to a manually operated table adapted to a large number
of positions in which the patient may be placed to facilitate the
examination by a physician.
Briefly the invention comprises a table with a stationary top with
one end stepped down lower than the other and with an adjustable
top made in three sections to operate over the stationary top.
The sectional table top can be quickly and easily adjusted so as to
support the patient with his head and trunk lowered, his buttocks
raised for examination and his legs in a kneeling position.
When lowered to the horizontal position all three sections of the
adjustable top are level. When raised for examination purposes
there is a wide choice of positions available to suit the
examination required.
The three sections of the adjustable top may be designated the head
section which supports the head and trunk, the thigh section which
supports the thighs, and the foot section which supports the knees,
lower legs and feet.
The step-down design of the head end of the table permits an
adequate slope for the head section during examinations.
The head and thigh sections are hinged together. The site at which
the foot section meets the thigh section can be raised or lowered
by means of a spring-loaded lever attached to the foot section. The
lever is provided with a dog and an adjustable plate formed with
notches. When the spring is compressed it releases the dog from the
notch, permitting the lever to raise or lower the site at which the
foot section meets the thigh section.
The head section and foot section are each provided with a ratchet
to retain that section in whatever position is desired for the
examination. The ratchet on the head section is engaged by a
transversely positioned rod, mounted on an extension from the head
section. When the table is raised for examination purposes this
extension engages the ratchet to maintain the desired position.
When the table top is level it supports the head section in a
horizontal position.
The ratchet on the foot section is engaged by a transversely
positioned rod hinged beneath the foot section.
A pad is provided over the entire surface of the table to protect
the patient.
The main object of the invention is therefore the provision of a
manually operated adjustable table to facilitate the examination of
a patient by a physician.
Another important object is the provision of a spring-loaded lever
to raise and lower the foot section of the said table.
Still another important object is the provision of a rod to engage
a ratchet to retain the head portion in an adjusted position.
Other apparent objects are the provision of an examination table,
as set forth, which is strong and durable, easy to operate and of
comparatively low manufacturing cost.
With these and other objects in view that may appear as the
description proceeds, the invention consists in the novel
arrangement of cooperating elements as hereinafter more
specifically set forth, claimed and shown in the accompanying
drawing forming part of this application and in which.
FIG. 1, is a side elevational view of an examination table,
constructed in accordance with the present invention and shown in
the closed position.
FIG. 2, is a side elevational view of the table shown in the raised
position.
FIG. 3, is a plan view of the table in the closed position.
FIG. 4, is a side elevational view of the height adjusting
plate.
FIG. 5, is a partial view of the operating lever to raise and lower
the foot section.
FIG. 6, is a partial view of the table in the raised or adjusted
position.
Referring more in detail to the drawing in which similar reference
characters designate corresponding parts throughout, it will be
seen the invention comprises a rigid section 10 mounted on a base
11. At the forward or head extremity of the base, a ratchet 12 is
provided and is positioned directly below the head section.
The head section 13 is formed with a depending fixture attached to
both sides to form legs to hold section 13 in a horizontal position
when lowered. Said legs are provided with a transversely disposed
rod 14 which engages the ratchet when that section is raised. It is
to be noted that the large number of notches in the ratchet 12
provides for a large variety of adjustment for that section. The
head section is formed in two parts which are hinged together at 15
by means of a continuous hinge to give the required strength to
such a device.
The knee end of Section 16 is activated by means of a spring loaded
lever 17 which is provided with a dog which engages a notched fixed
plate 18. The said plate 18 is attached securely to the stationary
table top 10 and has a plurality of notches to provide a plurality
of adjustments to the knee end of the section 16.
To raise both sides of section 16 evenly and simultaneously, a
through rod 19 is rigidly attached to lever 17 and has an arm on
the opposite end rigidly attached. Two extending arms, on section
16 extend downward to make a hinged connection with the arm and
lever rigidly attached to rod 19. When the lever 17 is activated
both sides of the knee end of section 16 move simultaneously.
To retain the foot end of section 16 in the desired position,
another ratchet 20 is provided and a hinged leg engages the
ratchet. Depending upon the height of the patient and the nature of
the examination, the foot section is adjusted accordingly.
It is believed that the construction and advantages have been fully
set forth and that further detailed description is not
required.
However, it is to be understood that minor modifications may be
resorted to without departing from the spirit of the invention.
