Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to push or pull carts and more
particularly to a novel and improved cart-type carrier adapted to
transport bowling balls, bowling shoes, and other bowling
accessories from point to point.
2. Description of the Prior Art
It has been known in the prior art to provide different types of
conventional hand propelled carts for the carrying about of garbage
cans, drums, golf carts, and the like, but none of such carts are
suitably adapted to transport relatively heavy bowling balls and
associated bowling accessories in a safe and secure manner between
different locations, such as within a bowling alley or the
like.
Thus, at the present time, bowling balls and associated bowling
accessories must be hand carried by use of bowling ball cases and
the like from an individual's car into the bowling alley, with this
being quite difficult for many elderly or handicapped individuals
in view of the great weight of the bowling ball and the distance
the same must be carried to the bowling alley.
Further, difficulties are experienced within a bowling alley as to
such a handicapped or elderly individual having to carry the
bowling ball from a storage rack normally positioned in one
location in a bowling alley to the particular alley on which the
individual is to bowl, this again being difficult and inconvenient
to such individuals.
SUMMARY OF THE INVENTION
The present invention recognizes the problems of individuals
relative to the carrying of bowling balls and associated bowling
accessories, such as shoes, towels, and the like, and overcomes
such difficulties by providing a novel bowling ball cart
specifically adapted for the carrying of bowling balls and bowling
ball bags between various locations.
It is an object of the present invention to provide a manually
operated cart which is lightweight but sturdy in construction and
which is adapted to carry bowling balls or bowling ball cases in a
safe and secure manner.
A further object of the present invention provides a cart
specifically adapted for the transporting of bowling balls and
accessories from point to point within a bowling alley or the
like.
Yet still a further object of the present invention provides a
wheeled cart readily pushed or pulled between locations and having
a platform on which bowling balls, bowling cases, and the like may
be temporarily rested in a secured manner preventing relative
movement on the the base and yet permitting the same to be readily
removed from the base without requiring any special instructions,
expertise, or the like.
The provision of a hand propelled cart for transporting bowling
balls and bowling accessories, such as briefly outlined above, and
possessing the stated advantages, constitutes the principal
features of the present invention. The provision of a cart which is
relatively simple in its construction and which therefore may be
readily manufactured at a relatively low cost and by simple
manufacturing methods; one which is relatively devoid of moving
parts and which therefore is unlikely to get out of order; one
which is rugged and durable and which therefore may be guaranteed
by the manufacturer to withstand many years of intended usage; one
which is aesthetically pleasing and refined in appearance; one
which is adapted to receive and transport bowling bags of different
sizes and configurations in a safe and secure manner thereon; and
one which, otherwise, is well adapted to perform the services
required of it, are further desirable features which have been
borne in mind in the production and development of the present
invention.
Other features and advantages of this invention will be apparent
during the course of the following description.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings in detail and in particular to FIGS.
1 to 5 inclusive, a preferred form of a cart constructed in
accordance with the present invention is designated in its entirety
by the reference numeral 10 and is comprised of three component
parts, namely a substantially flat rectangularly shaped base or
platform 11, an elongated tubular handle 12, and a wheel assembly
13.
The base 11 is of a flat rectangular shape having a front edge 21,
a back edge 22, opposed side edges 23 and 24, a top surface 25, and
a bottom surface 26. Projecting upright from the base 11 centrally
of each of the edges 21-24 are flanges 27, such as shown in the
drawings. Projecting co-planar with base 11 horizontally outwardly
of the central portion of back end edge 22 is a lip 28 having a
socket 29 welded to the top surface thereof and projecting upwardly
therefrom, the socket including a bore 30 extending longitudinally
axially therethrough which is provided with a screw type thread
about the peripheral inward wall surface thereof.
The handle 12 is of an elongated tubular construction having a
shank 31 terminating at the top end thereof in a handle grasping
portion 32 adapted to be grasped in the hand of an individual, with
the opposite end 33 provided with threads about the peripheral
surface thereof of a size and pitch complementary to the size and
pitch of the threaded bore 30 such that the same is threadedly
received in the socket 29 to detachably attach the handle 12 to the
base 11.
The wheel assembly 13 includes a pair of transversely spaced and
aligned winged V-shaped brackets 40 each depending downwardly from
the bottom surface 26 of the base 11 and fastened to the base by
fasteners 41 which may consist of screws, nuts, or the like.
Secured to the apex 42 of each bracket 40 and extending normal to
the axis of each bracket is a cylindrical bushing 43 having a bore
extending completely therethrough, each of the bushings 43 being
axially aligned with each other and adapted to rotatably receive
therethrough an axle 44 having a wheel 45 secured to each end
thereof such that the wheels 45 are rotatably supported relative to
the brackets 40.
In operation to carry a bowling ball 50 thereon, there is provided
a cylindrical ring like member 51 having an inner diameter adapted
to restingly receive the bowling ball therein, with the outer
diameter adapted to be received within the brackets 27 when the
ring 51 is rested on the top surface 25 of the base 11. It is to be
understood that the height of ring 51 is sufficient so as to retain
the bowling ball 50 out of contact with the base 11. Ring 51 thus
may be readily placed onto and removed from the base 11, with
bowling ball 50 readily inserted into or removed from the ring 51,
with the cart 10 being utilized to transport the bowling ball
between various locations without having to force the individual to
actually carry the weight of the bowling ball.
When it is desired to use a bowling ball case, such as case 52 of
FIG. 4 or case 53 of FIG. 5, then such cases are merely rested on
the top surface 25 of the base 11 and fit between the flanges 27 so
as to be securely detachably retained on the base 11 in a safe
manner, the case 52 provided with a hinged cover 54 and a hasp type
closure 55 with the case 53 provided with a hinged cover 56 and
hasp type closure 57, each of the cases 52 and 53 adapted to hold
therein a bowling ball and associated accessories, such as bowling
shoes and the like, in a conventional manner.
Referring now to FIGS. 6 and 7 there is illustrated a modified form
of the invention wherein there is provided a hollow box-like
rectangular container 61 having a top surface 62, a bottom surface
63, depending side walls 64 and 65, and depending front and back
walls 66 and 67 respectively. The top surface 62 is provided with a
circular opening 68 therein of a size and configuration adapted to
restingly receive a bowling ball 70 therein. The surfaces 62-67
define therebetween a compartment 69 which is completely closed
except for opening 68, and which is adapted to receive therein
bowling accessories, such as bowling shoes 71 and the like.
Further, projecting outwardly from the back end 67 is a lip 72
having a transversely extending slot 73 disposed therein and
adapted to be detachably engaged by a T-shaped end of a handle 75
as will be later described.
The handle 75 includes a shank 76 of an elongated tubular
configuration having a handle grasping end 77 adapted to be grasped
in the hand of an individual, with the opposite end 78 terminating
in a T-shape having a member 79 weldingly secured to end 78 about
its midpoint and projecting laterally outwardly normal to the axis
of the shank 76 a distance less than the length of the slot 73 in
lip 72, the end 78 and member 79 being of a diameter less than the
width of the slot 73 so as to be readily inserted into and removed
from such slot. To engage the handle to the container 61, member 79
is disposed over slot 73 and aligned therewith, after which the
member is moved vertically downwardly through the slot until
passing through the bottom end thereof, after which the handle 75
is rotated ninety degrees about its axis such that member 79 is
disposed substantially perpendicular to the axis of the slot 73. In
this position the handle is detachably attached to container 61,
with it being understood that to remove the handle from the
container the above procedure is reversed with the member 79 being
aligned with slot 73 and then being vertically withdrawn through
slot 73 to separate the handle from the container.
The container 61 is rotatably supported on a set of spaced apart
wheels 80 each rotatably connected by brackets 81 to the bottom
surface 63 of the container at spaced points thereabout, preferably
at each of the four corners, such brackets 81 being either
permanently affixed to the bottom surface 63 or rotatably affixed
thereto in a manner to permit rotation of the wheels 80 about their
axes as well as about an axis normal to the plane of the bottom
surface 63.
In operation, bowling shoes and accessories 71 are inserted through
opening 68 into the compartment 69, after which bowling ball 70 is
rested in the opening 68, after which the handle is detachably
attached to the container for pulling or pushing the container
about a supporting surface from point to point, such as between a
storage area in a bowling alley and the particular alley at which
the ball and accessories are to be utilized, with the handle being
readily detached from the container and stored separately therefrom
so as to be out of the way and yet readily accessible for use in
the transporting of the container.
It is to be understood that the form of this invention herewith
shown and described is to be taken as preferred examples of the
same, and that this invention is not to be limited to the exact
arrangement of parts shown in the accompanying drawings or
described in this specification as various changes in the details
of construction as to shape, size, and arrangement of parts may be
resorted to without departing from the spirit of the invention, the
scope of the novel concepts thereof, or the scope of the sub-joined
claims.
