DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0049] The form for constructing a circle for throwing a hammer and
shot put are shown in FIG. 1 through FIG. 4. The form for
constructing a circle for throwing discus is shown in FIG. 5
through FIG. 8. Both forms are very similar and are constructed in
the same manner. The differences between the two forms are dictated
by the requirements for a circle for throwing hammer and shot put
and a circle for throwing discus. The form for constructing a
circle for showing hammer and shot put will be described first but
the numerals used as to describe that form will also used for the
form for constructing a circle for throwing discus. The form for
constructing a circle for throwing discus will be described after
the form for throwing hammer and shot put but only to reflect the
differences. Parts which are different will be assigned a different
numeral.
[0050] The installation of the form is both fast and simple. Once
the form is completely assembled, as discussed hereinafter, an
excavation of the area is performed and is filled with crushed
stone. The form is placed on the crushed stone in a level position.
Cement is placed around and in the form up to the base of the
circle. Once the cement has dried, dirt is placed over the cement
only outside of the circle up to the top edge of the circle. The
cement floor in the circle is shaped with a slight rise in the
center of the circle to cause water to flow toward the edges of the
circle. Once constructed, the circle is recessed within the
surrounding ground.
Form for Hammer and Shot Put
[0051] Referring now to FIG. 1, the form is shown that is used to
construct a circle for throwing hammer and shot put (hereinafter
"Shot Put Form"). The Shot Put Form, when assembled, has a upper
surface 17 and a lower surface 19 and is essentially a square
having two side members 21 and two outer members 23. The circle 25,
for use by the player, is mounted generally in the center of the
square. The two outer members 23 and the side members 21 are
essentially the same length.
[0052] The circle 25 includes a toe board 27 which is located
toward one outer member 23 generally equally-spaced between two
side members 21. The toe board 27 is constructed with a length
suitable for more inexperienced players, most especially high
school students and also has marks 29 on it to indicate the length
of the toe board 27 for more advanced players, namely college
students. The toe board 27 is preferably secured to the circle 25
by bolts 31 and nuts 33.
[0053] Referring now to FIG. 4, it can be seen that the Shot Put
Form is preferably produced in a pair of half sections 35. Each of
the two half sections 35 are the same except for the toe board
27.
[0054] Each half section 35 has two half side members 37 and two
full side members 39, both of the two side members 37 are also
outer members 23 of the assembled Shot Put Form. Each half side
member 37 is substantially one-half the length of a full side
members 39. The half side members 37 are secured to the full side
members 39 substantially at right angles. At each corner 41 of each
half section 35, a brace 43 is installed to strengthen the corners
41.
[0055] A pair of semi-circles 45 are placed on the pair of half
sections 35. Each semi-circle 45 has a diameter 47 and the diameter
47 of each semi-circle 45 is placed along a full side member 39
generally equally distant between the half side members 37. The
full side members 39 where the diameter 49 of the semi circles 45
is located are inside full members 49 and the inside full members
49 of the pair of half sections 35 are placed together. The
opposite full side members 39 are the outside full members 50. When
the two half sections 35 are together with the inside full members
49 abutting one another, the two semi circles 45 form the circle
25. The two half sections 35 form a square. The circle 25 has a
circumference 51 and is generally located in the center of the Shot
Put Form.
[0056] Each half section 35 has two cross members 53 which are
parallel with the full side members 39, and extend from the half
members 35. The two cross members 53, namely an inside cross member
55 and an outside cross member 57 are generally evenly spaced
between the inside full members 49 and the outer members 23. The
circle 25 for the Shot Put Form is supported at two points by each
of the inside cross members 55 and at one point by each of the
outside cross members 57 where the circumference of the circle 25
just extends over the outside cross member 57.
[0057] As shown in FIG. 3 and FIG. 4, a plurality of tubes 59, that
are vertically oriented, are located about and secured to the
inside of the circumference 51 of the circle 25. These tubes 59
provide drainage from within the circle 25. The tubes 59 direct
water down to the crushed stone. As previously discussed, the
cement in the circle 25 is raised slightly higher in the center to
cause water to drain to the circumference 51 the circle 25 where
the tubes 59 are located. In the upper surface 17, notches 67 may
be cut into the inside full members 49 and the two cross members
53. The notches 67, which are used to hold Rebar, if desired, is
inserted into the notches 67. Rebar, however, is not actually
required. The notches 67 are aligned with one another generally
parallel to the half side members 37.
Form for Discus
[0058] The form that is used to construct the circle 61 for
throwing a discus (hereinafter "Discus Form") is basically
constructed in the same manner as the Shot Put Form.
[0059] The Discus Form is shown in FIG. 5 through FIG. 8 and does
not include a toe board 27. The circle 61 of the Discus Form is
larger that the circle 25 of the Shot Put Form. Due to the size of
the circle of the Discus Form 61, an outside cross member 53 is
placed closer to the outer member 23. Each inside cross member 65
is located substantially midway between the inside full member 49
and the outside cross member 53. Discus Forms are assembled and
installed in the same manner as are Shot Put Forms. Notches 67 for
Rebar may be added in the same manner as with the shot-Put Form.
The notches 67 are aligned with the side members and are placed in
the inside full members 49, the outside cross members 63 and the
inside cross members 65.
[0060] It is to be understood that the drawings and the description
are in all cases to be interpreted as merely illustrative of the
principles of the invention rather that as limiting the same in any
one way since it is contemplated that various changes may be made
in various elements to achieve like results without departing from
the spirit of the invention or scope of the appended claims.
