Claims
What is claimed as new and desired to be secured by Letters Patent
of the United States is:
1. In a pull type exerciser unit comprising a handle with a
plurality of spaced apertures formed therein, a plurality of
generally parallel spaced elongated members connected at their ends
to said handle, individual removable connections for said ends to
said handle, said individual removable connections comprising,
substantially closed loops on said ends, generally U-shaped spring
clips for attachment to said loops, said clips having close rings
integrally formed in the bite portion thereof each of said bite
portions extending outwardly in one uninterrupted continuous member
forming one of said rings, each of said U-shaped clips and rings
being formed of one continuous member, each of said rings
releasably engaging the loop on the end of each elongated member,
and integral stops formed on the opposite ends of the free ends of
each of said clips, said stops being adapted to removably lock said
clips in their respective handle apertures, and
wherein said unit further comprises said handle and another handle
identical to said handle spanned by said plurality of parallel
spaced elongated members, said elongated members comprising tension
members, said handles comprising open plastic material members and
said spaced apertures comprising flat through grooves formed in one
side of each of said handle, said stops further comprising integral
loops formed on the outer ends of said clip legs and integral
shoulders positioned on the legs of said clip and spaced from the
free ends thereof, and
wherein said spring clips are removably insertable within said
grooves, said integral stop loops being engaged with the outer end
edges of said grooves, and shoulders formed at the inner ends of
said grooves being engaged by said spring clip shoulders.
Description
This invention relates to exercising apparatus, and more
particularly, to improvements in chest pull type exercisers.
It is an object of this invention to provide a low cost adjustable
chest pull type exerciser which can be quickly and conveniently
adjusted without tools or loose falling parts.
Briefly, in the invention the tension cable or bands are
individually connected to their opposite handles by removable clips
which are self-retaining on the cable ends.
The features of the invention which are believed to be novel are
set forth with particularity in the appended claims. The invention
itself, however, both as to its organization and operation,
together with further objects and advantages thereof, may best be
understood by reference to the following description taken in
connection with the accompanying drawing in which:
FIG. 1 is an elevation view of one form of the invention;
FIG. 2 is an elevation view of another form of the invention;
and
FIG. 3 is a sectional view taken along the line 3--3 of FIG. 2.
Referring now particularly to the patent drawing, FIGS. 1 and 2
each show one end of an exerciser unit of the chest pull type. The
not shown opposite end of the units will be the same as shown in
these two FIGS. In FIG. 1 the invention is shown in connection with
continuous coil type tension springs 10 whereas in FIG. 2 the
tension members are rubber cords 11 which are fitted at their ends
with short coil springs 10' which are similar in construction to
the outer ends of the continuous coil type tension springs 10. That
is to say, the outer extremities of the springs 10 and fittings 10'
are provided with an integral closed turn, ring, or loop 10" .
These loops 10" are aligned with the lengthwise axis of the springs
10 or bands 11.
The handles 12 are open and preferably constructed from molded
plastic material. They are generally trapezoidal in shape and their
outer sides comprise hand grips 13 whereas their inner sides 14
have the opposite ends of the several tension members 10 or 11
individually removable connected thereto. In other words, in the
invention any one or more of the tension members 10 or 11 can be
removed or added without disturbing the others; and also, this can
be done in a quick manner merely with the bare fingers. Also, no
tools are required, and in addition, there are no loose falling
parts.
This is accomplished by special generally U-shaped spring clips 15,
see also FIG. 3, and a plurality of spaced apertures 18 formed in
the handle side 14. The bite portions of the spring clips 15 have
closed rings or loops 16 integrally formed thereon. Either one of
the legs 17 of spring clip 15 can be passed through the ring 10"
and then the legs 17 spread apart slightly to position the ring 10"
inside the ring 16. This locks the spring clips 15 on the ends of
the members 10 or 11 so that when they are removed from the handles
there are no loose falling parts.
The spaced apertures 18 in the handle are flat through grooves
which are specially shaped and dimensioned to closely receive the
specially shaped clips 15. In other words, the clips 15 are snug or
nearly snug in the grooves 18 so that there isn't excessive
looseness or rattling between the handles and tension members.
At their outer ends the spring clip legs 17 are turned outwardly
and then toward each other into integral loops 19. At their inner
ends the legs 17 are inwardly formed to provide integral shoulders
20. The inner ends of grooves 18 are formed with matching shoulders
21. Thus, the shoulders 20 engage the shoulders 21 and the loops 19
engage the outer edges of the grooves 18 when the spring clips are
in position in their handle apertures. In other words, shoulders 20
and loops 19 serve as stops for removably locking the clips 15 in
the grooves 18.
The curved portions or loops 19 also make it easy to remove the
clips 15. Opposite loops 19 can be gripped between the thumb and
fingers of the hand to squeeze the clips to withdraw them. To
insert them the flat parts of the legs 17 are squeezed to position
the loops 19 in the grooves. When they are pushed through the clips
snaps spring lock in position with the shoulders 21 engaging
shoulders 21 and loops 19 engaging the outer edges of the
grooves.
While there has been shown and described a particular embodiment of
the invention, it will be obvious to those skilled in the art that
changes and modifications may be made without departing from the
invention, and therefore, it is intended by the appended claims to
cover all such changes and modifications as fall within the true
spirit and scope of the invention.
