Description
BACKGROUND OF THE INVENTION
The diving board of the instant invention constitutes an assembly
which is completely portable and includes its own base which merely
requires that it is placed in a stationary manner relative to the
deck of an associated pool, the assembly may be anchored to the
pool deck if desired.
Heretofore, low diving boards have included strands or supports
therefor requiring sophisticated anchoring to an associated pool
deck, the diving board proper being supported from the stand in
cantilever fashion. Because of the cantilever fashion of supporting
the diving board proper, these more conventional types of diving
board constructions place excess stresses and strain on the
portions thereof which are anchored to the pool deck. The
amplification of stresses and strain at the point of anchoring of a
diving board construction to the deck often results in failure of
the anchoring structure and the need for frequent repairs.
Although there has been some development in diving board
constructions which do not require the support of a diving board
proper and the strand therefor in cantilever fashion from the deck
of a swimming pool, this field of invention has not been fully
developed. Previous springing devices which are generally similar
to the diving board construction of the instant invention may be
found in U.S. Pats. Nos. 3,300,209 to C. Friis, dated Jan. 24,
1967, 2,812,180 to L. P. Cymbal, dated Nov. 5, 1957, and 2,764,413
to K.M. Wisner, dated Sept. 25, 1956. However, these previous
springing devices do not include the refinements of construction
incorporated in the diving board of the instant invention. The
diving board construction incorporates a base structure which
extends the full length under the diving board proper with the
latter pivotally supported at one end in elevated position relative
to and from and corresponding end of the base and an upstanding
compression spring disposed between upwardly and downwardly facing
intermediate portions of the base and diving board proper,
respectively. By this construction, the stresses and strain of a
person using a diving board are evenly distributed to the
associated pool deck throughout the entire length of the base
portion of the diving board construction.
The main object of this invention is to provide an improved diving
board construction including structural and
operationalcharacteristics which will enable the diving board
construction to be portable without the need for being anchored to
an associated pool deck or the like and which will provide the
desired springing action of better conventional diving board
constructions.
Another object of this invention, in accordance with the
immediately preceding objects is to provide a diving board
construction that may be readily serviced by inexperieced persons
when service thereon is required.
A final object of this invention to be specifically enumerated
herein is to provide a diving board construction in accordance with
the preceding objects and which will conform to conventional forms
of manufacture, be a simple construction and be easy to use so as
to provide a device which will be economical, feasible,
long-lasting and relatively trouble free in operation.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The numeral 10 generally designates a pool deck extending about a
pool well 12 having water 14 disposed therein to a level 16 below
the upper surface of the deck 10.
The diving board construction of the instant invention is referred
to in general by the reference numeral 18 and includes a base
structure referred to in general by the reference numeral 20, a
diving board element 22 and a compression spring 24 interposed
between upwardly and downwardly facing vertically spaced
mid-portions of the base 20 and diving board element 22.
The base 20 includes a pair of elongated horizontal and generally
parallel opposite side members 26 and 28 comprising angle members
including upstanding mounting flanges 30 and horizontal base
flanges 32. The base flanges 32 project outwardly from the remote
sides of the lower marginal edge portions of the mounting flanges
30 and the mid-portions of the angle members 26 and 28 are rigidly
interconnected by means of a horizontal transverse brace 34
extending and secured between adjacent sides of the mounting
flanges 30. The transverse brace 34 comprises an inverted
channel-shaped member including an upper horizontal bight portion
36 interconnecting opposite side depending flanges 38.
The base is placed on the pool deck 10 and although the side
members 26 and 28 need not be anchored in position, a plurality of
fasteners 40 may be secured through each of the base flanges 32 at
points spaced longitudinally therealong and anchored to the deck
10, if desired. The opposite side members 26 and 28 extend away
from the pool well 12 and the ends of the side members 26 and 28
remote from the well 12 include upstanding mounting plates 44 whose
lower marginal edge portions are rigidly secured to the opposing
inner sides of the mounting flanges 30 in any convenient manner
such as by welding. The upper portions of the mounting plates 44
are interconnected by means of a large diameter horizontal
transverse tubular member 46 extending between and having its
opposite ends rigidly secured, as by welding, to the upper portions
of the inner sides of the mounting plates 44.
A pair of eye bolts 48 are secured downwardly through the tubular
member 46 and anchored in position by means of threaded bolts 50
threaded onto the lower ends of the eye bolts 48 which project
below the tubular member 46. The eye portions 52 of the eye bolts
48 project above opposite end portions of the upper periphery of
the tubular member 46 and rotatably receive the opposite end
portions of a pivot shaft 54 therethrough.
Diving board element 22 is placed above and generally parallels the
base 20. The under surface of the end of the diving board element
22 overlying the tubular member 46 includes clamp members 56
secured about the pivot shaft 54 at points spaced immediately
inwardly of the eye portions 52 of the eye bolts 48 and the clamp
member 56 are anchored by fasteners 58 to the underside of the
diving board element 22. The diving board element 22 generally
parallels the base 20 and extends therealong in spaced relation
relative thereto toward the pool well 12. The lower end of the
large diameter compression spring 24 is anchored, as by spot
welding 60, to the center portion of the transverse brace 34 and
the upper end of the compression spring 24 is anchored to the
underside of the mid-portion of the diving board element 22 by
means of fasteners 62 secured through mounting ears 64 carried by
and projecting outwardly of remote sides of the upper convolution
of the coil spring 24.
From the foregoing it may thus be seen that the diving boarad
element 22 does not project appreciably beyond either end of the
base 20 and that the base 20 may be readily anchored to the deck
10. Further, the placement of the compression spring 24 between the
underside of the mid-portion of the diving board element 22 and the
transverse brace 34 insures that substantially all stresses and
strain transferred to the base 20 during use of the diving board
construction 18 will be evenly distributed throughout the base 20
to the deck 10. Also, the pivotal connection of the base end of the
diving board element 22 may be readily serviced and either the
pivot shaft 54 and/or the eye bolts 48 may be replaced whenever
needed. Also, the diving board element 22 may be readily removed
from the rest of the diving board construction 18 by removal of the
fasteners 62 and the fasteners 58.
Further, the lower end of spring 24 may be removably fastened to
the transverse brace 34 by means of removable fasteners and channel
members may be used in lieu of the angle members 26 and 28, if
desired.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention.
