FOLDING TRIPOD CONSTRUCTION
U.S. Pat. No. 2,668,682
A tripod of light and rigid construction has adjustable feet by which it
may be adapted for use either on a flat interior floor such as a hardwood
or marble floor, or alternatively, can be adjusted for use on rough
ground. A good construction incorporates a universal joint, thus allowing
the feet to accommodate to different angular adjustments of the tripod or
uneven ground. In each adjustable foot is a means to present either a flat
support surface for use on floors, or a retractable spur which may be
thrust into the ground when the tripod is used out-of-doors. A linkage
system is for rigidly interconnecting three legs of the tripod when the
same is in an expanded position for use. A latch mechanism is for
simultaneously latching the legs in a closed position when the tripod is
folded for transportation. An under side of a head is readily accessible
for attaching or detaching tilt heads and other objects on the top of the
tripod.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Turning now descriptively to the drawings, in which similar reference
characters denote similar elements throughout the several views, FIGS. 1
through 5 illustrate a portable hair styling and barber chair 10,
comprising a lightweight collapsible tetrapod bass unit 12. A lightweight
foldable seat assembly 14 fits upon the base unit 12. When the seat
assembly 14 is disassembled from the base unit 12, the chair 10 can be
carried with little effort from place to place and can conveniently fit
into a trunk of an automobile.
The base unit 12 includes a center post 16. Four leg subassemblies 18 are
radially hingedly secured about the center post 16. They support the
center post 16 in an upright position when the leg assemblies 18 go from a
collapsed position A against the center post 16 to an extended position B.
The center post 16 consists of a hollow cylindrical column 20. Four
stationary lugs 22 are radially attached about a bottom end of the column
20. An annular stop 24 is affixed to the column 20 approximately one third
the distance down from a top end of the column 20. A slide swivel 26 is
carried on the column 20 between the annular stop 24 and the top end
thereof.
The slide swivel 26 contains a collar 28, which rides upon the column 20.
Four arms 30 are radially attached about the collar 28. A setscrew 32 is
for securing the collar 28 to the column 20, when the leg assemblies 18
are in the extended position B.
Each leg subassembly 18 includes a leg 34 having an approximately forty
degree bevel cut foot 36 formed on a lower end thereof. A first structure
38 is for pivotally securing an upper end of the leg 34 to one of the arms
30 of the slide swivel 26. A strut 40 is provided. A second structure 42
is for pivotally securing a first end of the strut 40 to one stationary
lug 22 on the column 20. A third structure 44 is for pivotally securing a
second end of the strut 40 to the leg 34 approximately half the distance
down from the upper end of the leg 34. The foot 36 of the leg 34 can rest
safely upon a flat surface 45, when the leg 34 is in the extended position
B.
The first pivotally securing structure 38 consists of the leg 34 having a
forked part 46 integrally formed on the upper end. A distal end of the arm
30 of the slide swivel 26 can fit into the forked part 46. A first pivot
pin 48 extends through the forked part 46 of the leg 34 and the distal end
of the arm 30.
The second pivotally securing structure 42 comprises the stationary lug 22
having a forked part 50 integrally formed on a distal end. The first end
of the strut 40 can fit into the forked part 50. A second pivot pin 52
extends through the forked part 50 of the stationary lug 22 and the first
end of the strut 40.
The third pivotally securing structure 44 includes a third pivot pin 54, to
extend through the second end of the strut 40 and the leg 34. The base
unit 12 further contains a height adjuster member 56, having a control
lever 58. The height adjuster member 56 is mounted onto the column 30, so
as to raise and lower the seat assembly 14 therefrom.
The seat assembly 14 includes a seat 60. A backrest 62 is hinged to the
seat 60 at 64. A spindle 66 extends downwardly from a lower surface of the
seat 60, to engage with the height adjuster member 56. A handle 68 is
affixed to a rear edge of the seat 60. When the spindle 66 is removed from
the height adjuster member 56 and the backrest 62 is folded down upon the
seat 60, the seat assembly 14 can be easily transported by a person 70
grasping the handle 68, as shown in FIG. 4.
A carry case 72 is of a size and shape to retain the base unit 12 therein,
when the leg assemblies 18 are in the collapsed position A. The base unit
12 can be easily transported by the person 70 holding the carry case 72.
