COMPLETE SPECIFICATION.
An Improved Stand for Cameras, Geodetic Instruments, and the like.
I, CARL PAUL GOERZ, of Friedenau, near Berlin, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of this invention is a light and easily transportable stand for photo-
graphic cameras, geodetic instruments and the like, consisting of metal tubes and
so arranged that it can easily be put into a casing of the form of a hollow stick
when not in use. It differs from known stands in the fact that it is not necessary to
pull the single legs out by hand in order to bring them to their full length but
in drawing it out of the casing all the legs are automatically prolonged so that
the drawn out stand is at once ready for use. On the other hand there is no
need to shorten each leg separately in order to put the stand back into its casing
but it is sufficient to put the drawn out legs into the casing by which the locking
devices are in due course set free so that the prolongations can be pushed into the
tubular upper parts of the legs by the same action as causes the stand to be
pushed into its casing.
The annexed drawing shows in
Fig. 1 a longitudinal section of the stick like casing containing the closed
stand.
Fig. 2 shows the top end of the casing and illustrates the manner in which the
prolongations are drawn out.
Fig. 3 represents also in enlarged scale the lower end of the casing while the
stand is being pushed in, at the moment when the prolongations begin to enter
into the hollow upper parts of the legs.
Fig. 4 is a section on line 4, 4. Fig. 1.
The stand consists of metal tubes a of such a sectional shape that they form
when put together, a body of exactly annular or circular section. The legs are
fastened in the known manner at the upper end to a plate destined to receive
the camera or the like. Suitable devices limiting the spreading out of the legs
may be provided, but form no part of this invention. Into the upper parts of the
legs prolongations d of suitable sectional shape are pushed in, ending at their
lower ends in points provided at their upper ends with elastic studs c flattened
above, engaging under the lower end of tubes a as a safeguard against unin-
tentional collapsing is a hollow stick into which the stand can be pushed. Its
interior is of such a size that it can just receive the stand when closed. The
stick is provided in the known manner with a screwed on cap.
When the stand is drawn out of the stick nothing alters in the position of the
legs one to another till the points of the prolongations d reach the end of the
For this
hollow stick, but they are then held and pulled out of the tubes a.
purpose a metal socket is put upon the upper end of the stick b carrying inside
an annular flange 7 sharp edged at its lower end. Where the points e of the
prolongations join the straight parts & a projecting shoulder f is formed having

Fig. 2 the ends e of the legs d in consequence of their elasticity are pressed
against the walls of tube b, that is to say, against ring g, the projection
engages under the ring flange 7. On further pulling out of the top of the head
the prolongations d are drawn out of the upper parts a.
When on the other hand the stand is folded together and pushed into the
stick the elastic studs c are met and pushed back by the upper end of the stick
or by the socket g thereon so that the lower end of tube a does not continue to
rest on the flattened part of the studs c. When the ends of the prolongations d
have reached the lower end of the hollow stick b and the stand is then still further
pushed in, the lower edges of the upper parts a will press back the oblique parts
of the elastic studs thus pressing them still further to. the inside, so that the
part a can be freely pushed over parts d.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim is
1. The combination of a stand with a stick-like casing whereby the telescopic
legs forming the stand are automatically prolonged when taken out of the casing
and shortened when pushed therein.
2. A form of construction of the invention of Claim 1 wherein the prolonga-
tions telescoping in the hollow legs a are provided near their ends with
projecting noses e flattened above, engaging under a ring flange / arranged on
the top end of the casing and flattened on its under side whilst they carry on
their top ends elastic studs c flattened on a part of their upper sides for holding
the prolongations d in their drawn out position, said buttons being adapted to be
pressed back so far by the walls of the hollow casing that the parts of the legs
can be telescoped when the legs are pushed into the casing.
