Abstract
A floor for a bumper car amusement ride is of modular construction. A base of each module may be of wood and has a multitude of openings for inserted reception of threaded studs welded to the underside of sheet metal panels extending lengthwise thereof. Nut elements, upon removal, permit panel removal and replacement. Dielectric spacers on each base insulate metal panels of different polarity. A metal framework supports the floor modules.
Description
BACKGROUND OF THE INVENTION
The present invention pertains generally to modular floor construction with the modules having conductive panels in place thereon.
In amusement ride concessions for small electrically powered vehicles termed bumper cars, the power source for each car includes electrically conductive modules in place on a floor with each car provided with electrical pickups or shoes which in circuit with the car motor. Typically, the floors for such amusement rides consist of modules, several square feet in area, in abutment with one another with each module having multiple electrically conductive plates thereon. After a period of operation it is not uncommon that wear or damage will occur to one or more of the modules requiring panel removal and replacement with a new module. Accordingly, while a module may have only one conductive panel damaged, the entire module is removed and replaced at considerable cost and effort to the concession operator. A quantity of replacement modules may be stored on the site or ordered from a supplier with the drawbacks being the original cost of same and the storing of multiple modules ordering modules on an as needed basis which entails shutting down of the amusement ride for one or more days with loss of income. A prior practice in the construction of floor modules is the permanent securement of each conductive panel to the module, often a sheet of plywood. Additional problems can be encountered upon warping of the plywood base causing an uneven surface on the module which is objectionable.
SUMMARY OF THE PRESENT INVENTION
The present invention pertains to a floor module with conductive panels thereon with the panels being individually replaceable on the module.
The present floor module utilizes conductive metal panels on its surface from which current is taken by pickups on an amusement vehicle or bumper car to provide power to the vehicle motor. Both positive and negatively charged panels are in series with one another. The present floor module utilizes a base which is provided with a pattern of openings therethrough for reception of fasteners carried by a conductive panel in place on the module surface. The fasteners retain the conductive panels while permitting individual removal and replacement of a damaged panel. Accordingly, the cost of refurbishing a defective floor module is greatly reduced when compared with the previous practice of replacing an entire floor module with perhaps only one defective panel.
Important objectives of the present invention include the provision of a modular floor comprised of modules each having a base configured to received superimposed, electrically conductive panels in an individually attached manner permitting panel replacement at considerable savings when compared with replacement of the entire floor module; the provision of a floor module for use in a floor of modular construction wherein each module has multiple conductive panels thereon with the panels being detachable upon removal of fastener components from studs carried by the conductive panels to permit convenient panel replacement and prompt return of the module to minimize down time of an amusement ride; the provision of a floor module which may be refurbished by the ride operator with use of common place tools and requiring minimal expertise on the operator's part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
With continuing attention to the drawings wherein applied reference numerals indicate parts similarly hereinafter identified, the reference numeral
1
indicates generally a floor module, a multitude of which constitute a modular floor for an amusement ride.
With continuing attention to the module at
1
and
FIGS. 1 and 2
, a module base at
2
is preferably rectangular, and of dielectric material such as wood, for example. The base defines channels as at
3
cut or formed in the base to receive dielectric spacers at
4
with countersunk openings at
5
spaced therealong for the reception of fasteners
6
. In addition to securing spacers
4
to base
2
the fasteners extend into threaded engagement with a tubular metal member
7
of a floor framework shown in FIG.
7
. Similarly, dielectric spacers at
10
along the sides of module
1
are secured to underlying base
2
on a shoulder
9
therein by fasteners
11
which terminate in threaded engagement with a tubular framework member
7
. The spacers, shoulder and framework are drilled to receive fasteners
11
of the self tapping type. Accordingly, module
1
is secured to framework
7
in a secure yet detachable manner. Dielectric spacers
4
and
10
serve to isolate the following described conductive panels in place on each module as well as conductive panels on laterally adjacent modules of the amusement ride floor.
Raised or elevated areas
13
of the base are defined by channels
3
and shoulders
9
with the raised areas laterally offset or spaced apart from like raised areas with each receiving an overlying conductive panel
14
. The conductive panels extend lengthwise of the module with their ends and sides at
15
and
16
abutting the perimeter
17
of each raised area
13
of a module. A suitable material for the conductive panels is stainless steel of
18
gauge with lips
15
and
16
projecting downwardly approximately one-quarter of an inch.
Carried by each conductive panel is a multitude of threaded studs
19
attached as by use of a stud welder, which project downwardly from the panel and extend through an opening
18
in base
2
. A counterbore
20
receives a nut
21
and washer to draw panel
14
into snug surface engagement with the upper surface of raised area
13
. Counterbore
20
is of a diameter to accept a wrench socket to permit convenient unfastening of nut
21
during removal of a conductive panel
14
from the module. With attention to
FIG. 2
, it will be seen that each module of the floor is bored at multiple locations
13
to securely affix the panel to base
2
surface yet permitting individual panel removal for refurbishment of a module in the event of damage to a panel.
With attention to
FIG. 4
of the drawings, an electrical terminal is indicated generally at
22
and serves to put a conductive panel
14
in circuit with a panel, of like polarity, on an adjacent module. A cable
23
terminates in a blade
24
which is secured to a post
25
which may be the shaft of a threaded fastener of the flat head type recessed or offset below the panel surface apertured at
26
. A nut
27
draws the fastener
25
snugly against a conically recessed plug
28
for surface engagement with the marginal surface of opening
26
in panel
14
. Installation of the present module is in endwise abutment with an adjacent module of like polarity. The panels
14
of each module will be of alternate polarity for the purpose of providing a current flow to an electrically propelled car, termed bumper car in the United States of America, of an amusement ride. Such cars are equipped with panel engaging shoes which complete a circuit between adjacent panels of the same or adjacent modules.
Repair of a module having a damaged panel
14
entails the removal of nut elements
21
from studs
19
of the damaged panel, whereupon the panel is lifted from the raised area
13
and a new panel substituted with the studs
19
of the new panel being inserted into openings
18
in the panel base.
While a framework
7
is shown, the modules
1
may be set directly on a floor surface with the modules joined by steel stringers inset into the underside of each module.
The panel lips
15
,
16
contribute to panel securement in the module base and also avert panel damage by a vehicle carried shoe.
While I have shown but a few embodiments of the invention, it will be apparent to those skilled in the art that the invention may be embodied still otherwise without departing from the spirit and scope of the claimed invention.
Having thus described the invention, what is desired to be secured by a Letters Patent is:
