Abstract
The present invention provides a fingerboard ramp having a base having at least one riding surface and a metal rail or a metal coping attached to the base to provide an additional riding surface for a fingerboarder.
Description
FIELD OF THE INVENTION
The present invention applies to amusement ramps and methods for constructing same, and, more particularly, to fingerboard and skateboard ramps.
DESCRIPTION OF THE PRIOR ART
Ramps for fingerboards and skateboards are known in the art. Fingerboarding is the imitation of skateboarding using the fingers, a miniature skateboard (fingerboard) and optionally, a miniature ramp for performing stunts imitating the stunts performed by a skateboarder. These ramps are used for performing stunts by the riders and are also for use with roller skates, in-line skates and BMX bikes. For example, Schlesinger, U.S. Pat. No. 4,129,916 discloses an Adjustable Skateboard Ramp, Romero, U.S. Pat. No. 4,285,514 discloses a Ramp Device for Practicing Wheeled Sports, Farnen, U.S. Pat. No. 5,524,310 discloses a Modular Halfpipe Skateboard Ramp and Method of Constructing and Sheehan, U.S. Pat. No. Des. 257,874 and Firestone, U.S. Pat. No. Des. 258,460 show designs for skateboard ramps. These references disclose a number of different designs of ramps and methods for constructing the ramps. Some of these references disclose the use of one-piece unitary riding surfaces, while other ramps known in the prior art disclose the use of multi-piece riding surfaces.
Further, none of the toy fingerboard ramps heretofore known offered by others utilize metal railings and/or copings and thus, lack realism as compared to actual full-sized skateboard ramps.
SUMMARY OF THE INVENTION
The present invention provides a ramp having an underlying supporting structure and a ramp section having a unitary riding surface. The supporting structure includes a pair of side frames of similar shape. The two side frames are connected together by a plurality of crossbraces to form a supporting structure with an upper supporting surface generally having a desired shape of the finished ramp. The ramp section can be constructed of a unitary piece of material or of a composite construction. It is generally flat and constructed to have enough flexibility to conform to the upper supporting surface of the supporting structure to provide the desired ramp shape while having enough stiffness to properly support the rider. The supporting frames are each provided with at least two locating tabs that project above the upper supporting surface of the supporting structure to engage corresponding notches in the ramp section. In this way, the ramp section can be initially installed on the supporting structure and will be held in place by the engagement of the tabs with the notches until the ramp section can be more securely fastened to the supporting structure. This self-locking mechanism allows one person to temporarily position and install the ramp section to the supporting structure so that the ramp section can then be secured to the supporting structure for use by the riders.
In an alternative embodiment of the present invention, the fingerboard ramp is constructed of plastic or other formable material and is formed by molding or vacuum forming. Provision is made for attaching metal railings and/or copings to the ramp. Since actual full-sized skateboard ramps use metal railings and copings, the metal railings and copings of the fingerboard ramp give a more realistic appearance to the fingerboard ramp. Further, the sound and feel made by a skateboarder on a skateboard ramp when the skateboard contacts and slides along the metal components is distinctive. Thus, the metal railings and copings of the fingerboard ramp also provide a more realistic sound, feel and experience to the fingerboarder when the fingerboard contacts and slides along these metal components. These advantages are not provided in fingerboard ramps having nonmetallic railings and copings.
It is an object of the present invention to provide an amusement ramp having a supporting structure and a ramp section, whereby the ramp section can easily be installed to the supporting structure by one person.
It is a further object of the present invention to provide an amusement ramp having a supporting structure and a ramp section, whereby the ramp section can easily be temporarily installed to the supporting structure by one person to subsequently allow for more secure installation.
It is a further object of the present invention to provide a method for installing a surface section to a supporting structure whereby tabs on one of the surface section or the supporting structure engage notches or slots in the other of the surface section or supporting structure to position and hold the surface section with respect to the supporting structure.
It is a further object of the present invention to provide a fingerboard ramp utilizing metal railings and/or copings to provide a more realistic sound, feel and experience to the fingerboarder.
The foregoing and other objects, features, characteristics and advantages of the present invention, as well as the methods of operation and functions of the related elements of structure, and the combination of parts and economies of manufacture, will be apparent from the following detailed description and the appended claims, taken in connection with the accompanying drawings, all of which form a part of the specification, wherein like reference numerals designate corresponding parts in the various figures.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1
shows a perspective view of a ramp
10
of the present invention. The ramp includes a pair of side frames
12
and
14
(side frame
14
can be seen in FIG.
3
). Each side frame has a plurality of notches
16
for supporting a like plurality of crossbraces
18
. Each crossbrace
18
is positioned in a corresponding pair of notches
16
in the side frames
12
and
14
to attach the two side frames together and form a supporting structure. The crossbraces can be attached to the side frames by any known method, including glue, screws, nails, brackets, etc. Each crossbrace
18
can be constructed from a unitary piece of material or, as shown, can be constructed from two separate pieces of material
20
and
22
and attached together, again by any known method. Depending on the length of the supporting structure, it may be desirable to add one or more center frames to the structure to strengthen it. These frames can be shaped like the side frames (with or without the locating tabs discussed below) or can be truncated. The center frame or frames can be shaped as shown in
FIG. 3
, wherein center frame
44
has truncated sides as compared to the side frames, and does not include any locating tabs.
Each side frame also has two supporting surfaces
24
and
26
. Supporting surface has two extending locating tabs
28
and
30
and supporting surface
26
has two extending locating tabs
32
and
34
. Supporting surface
24
supports a ramp section
36
and supporting surface
26
supports a ramp section
38
. As can be seen in
FIG. 5
, ramp section
36
is of a generally rectangular shape and has two locking notches or slots
40
and two locking notches or slots
42
. The locking notches
40
are adapted to engage the locating tabs
28
on side frames
12
and
14
and the two locking notches
42
are adapted to engage the locating tabs
30
on side frames
12
and
14
. The locating tabs
28
(and correspondingly, the locking notches
40
) can be the same width as the locating tabs
30
(and correspondingly, the locking notches
42
) with both tabs and notches symmetrically located so that the ramp section has no specific required orientation with respect to the supporting structure. Alternatively, the notches and tabs can be of different widths and/or spacing so as to require a specific orientation of the ramp section to the supporting structure upon installation. Since in this embodiment the two ramp sections
36
and
38
are similar to each other, the description above with respect to ramp section
36
would also correspondingly apply to ramp surface
38
.
While the supporting surfaces
24
and
26
are curved, the ramp sections
36
and
38
are generally flat in their relaxed state. In such situations, it is often difficult to position the ramp sections and get them to conform to the curved supporting surfaces without additional hands, holding weights and/or clamping mechanisms. However, the provision of the locking notches and locating tabs minimizes or eliminates such need.
The distance between notches
40
and
42
is set to be the same distance between the tabs
28
and
30
along the curve of the supporting surface
24
(the arc length). This distance is longer than the straight-line distance between the tabs
28
and
30
(the chord length). By positioning ramp section
36
so that the notches
40
engage the locating tabs
28
, the ramp section can then be carefully pressed in toward the supporting surface
24
while being held in place by the locating tabs
28
. As the ramp section
36
is pressed into to place to conform to the supporting surface
24
, starting from the notches
40
and working toward the notches
42
, the notches
42
will come into alignment with the tabs
30
so that the this end of the ramp section can be pressed against the supporting surface to engage notches
42
with tabs
30
. The force of the ramp section
36
trying to return to its relaxed, flat state causes a spring lock between the notches
40
and
42
and tabs
28
and
30
, respectively, thereby temporarily holding the ramp section in place until more secure or permanent fasteners can be utilized or take effect (such as glue). Depending on the specific design of the ramp and materials, the spring lock may be sufficient to hold the ramp section to the supporting structure without additional fasteners. The tab/notch engagement is also believed to improve the overall strength of the secure attachment between the ramp sections and the support structure by helping to maintain a secure positioning between the two.
This effect can usually be accomplished by the use of two tab/notch pairs at the outer ends of the curve as shown with the above embodiment, but if desired, additional tab/notch pairs can also be utilized. Further, even if the supporting surface is not curved, but flat, the tab/notch pairs can be used to accurately position and hold the ramp section to the supporting surface, although no spring locking will be in effect under such circumstances. Alternatively, the ramp section can be provided with tabs for engaging notches in the supporting structure or can utilize a combination of tabs and notches for engaging a corresponding combination of notches or tabs on the supporting structure. Although the tabs and notches are shown to be rectangular, they can be of any desired shape, including round, triangular, etc. The tabs and notches need not be provided at the edge of the ramp section/supporting structure but can be provided elsewhere on the ramp section/supporting structure. The notches are shown herein to be open on one side but they can also be closed on all sides and need not completely pierce the ramp section/supporting structure but may be in the form of blind holes. Alternatively, the ramp section and supporting structure can be provided with pre-existing bores that will align when the ramp section is pressed down to conform to the support surface such that pins, bolts, or screws, etc. can be inserted through the aligned bores to retain the ramp section to the supporting structure.
The ramp
10
also includes an edge coping at the intersection of the ramp sections
36
and
38
to provide a uniform, durable contact surface. The edge coping
44
in the preferred fingerboard embodiment is constructed of round metal tubing and glued to the ramp, but other materials, shapes and methods of attachment can also be utilized.
The ramp of the present invention can be constructed of various types of materials. For, instance, the ramps can be constructed of wood, plastic, cardboard or metal and different materials can be used for different components. In one multi-piece embodiment of the present invention used as a fingerboard ramp, the ramp is constructed from die-cut pieces of relatively thin, soft wood sheets. The sheets can be of the same thickness or have different thicknesses for different components. It may also be desirable to construct the ramp section from a harder wood or other material to provide increased durability. Also the ramp section can be of a uniform material or can be of a composite construction of multiple layers, pieces or materials. While a bottom surface of the ramp section can be segmented, it is preferred, though not required, to maintain the top riding surface of the ramp section as a single unitary piece to provide an enhance riding surface. This provides an improved riding surface as compared to multi-piece riding surfaces of prior art devices.
In this fingerboard embodiment, the components are presently held together with glue. Further, the glue for attaching the ramp section to the supporting surface is preferably applied to the contacting surfaces prior to assembly but can also be applied after assembly and locking of the ramp section to the supporting surface. In a larger embodiment, additional fastening mechanisms will likely be desired, including screws, bolts, nails, clamps, soldering, welding, etc. Alternatively, as discussed above, the tab and notch assembly of the components may be sufficient to hold the ramp together without further fasteners such as adhesives. In the fingerboard embodiment, a kit is provided with all of the necessary cut pieces for assembly by the user. The present invention makes it easier for the user to assemble the pieces into a finished ramp, especially when the user may be a teenager or younger child who has not developed the desired dexterity or may have limited additional tools to assist with the assembly. With smaller ramps such as fingerboard ramps, the assembly can be accomplished by a single person. Of course, larger ramps for skateboards, in-line skates, bikes, snowboards, etc., may require additional individuals for assembly. Further, the fingerboard ramp of the present invention can also be used for miniature in-line skates, miniature bicycles, miniature snowboards, etc.
An alternative embodiment of the present invention is shown in perspective in FIG.
6
. This ramp
70
includes two curved sections
72
and
74
facing each other and joined together by a flat intermediate section
76
. Other than the shape of ramp
70
, its construction is similar to the construction of ramp
10
. A ramp section
78
is provided which includes a plurality of notches
80
which engage a like plurality of tabs for holding the ramp section
78
in place upon installation. In this embodiment, because of the relative length of the ramp section, it has been found to be desirable to align and engage the four middle notches
80
bordering the intermediate section
76
with the corresponding tabs
82
first and then holding this portion in place with a weight (such as a book) prior to engaging the outermost notches and tabs. This prevents the middle notches from disengaging from the middle tabs as the remaining notches are engaged with the remaining tabs. In another alternative embodiment, a halfpipe-shaped ramp can be constructed similarly to the ramp
70
by not providing the flat intermediate section
76
between the two curved sections
72
and
74
. Alternative ramp shapes can also be utilized, including ramps where the side frames are not parallel to each other but can be at an angle to each other to form with the ramp section, for instance a truncated partial cone-shaped ramp. The present invention can also be applied to other types of structures where a surface sheet is being attached to a supporting structure.
In an alternative embodiment of the fingerboard ramp, as seen in
FIG. 7
, a ramp
100
includes a base
102
constructed of plastic as a unitary component. The base
102
can be molded, blow-molded, injection-molded, roto-molded, thermoformed, vacuum formed or constructed by other known methods. The configuration of the ramp
100
includes a platform
104
, a “half-pipe” section
106
a “spine”
108
and a “quarter-pipe” section
110
. Ramp
100
includes two metal copings
112
and
114
attached to the base
102
. A fingerboarder
116
is shown engaging a fingerboard
118
. In the presently preferred embodiment of
FIG. 7
, the base is approximately 6.25″ high to platform 104, 28″ long and 8.5″ wide.
In a further alternative embodiment of the fingerboard ramp seen in
FIG. 8
, a ramp
120
includes a base
122
constructed of plastic as a unitary component. The ramp
120
includes a number of differently configured riding surfaces, such as platforms
124
and
126
, inclined ramp
128
and curved ramps
130
,
132
,
134
and
136
. Rails
138
,
140
and
142
are attached to the base
122
and are differently configured to coordinate with the different riding surfaces to provide a series of unique riding positions to the fingerboarder. In the presently preferred embodiment of
FIG. 8
, the base is approximately 3″ high to platform 124, 16″ long and 13.25″ wide.
FIG. 9
shows one method of attaching a rail to the base of a ramp. A cavity
144
is provided in the base
122
for accepting an end of rail
140
. In this embodiment, the cavity
144
is molded into base
122
, but can alternatively be pierced or machined into the base. An adhesive
146
can optionally be used to provide additional strength to the rail/cavity joint, as can a screw
148
engaging the rail
140
and base
122
. This method can be used for any of the ramp embodiments disclosed herein. While the rail
140
is shown to be hollow, it can also be solid, as can the rest of the rails and copings disclosed herein. The metal rails can be aluminum, steel or other metal and can be interchanged as desired to provide different feel and sound to the fingerboarder.
FIG. 10
shows a further alternative embodiment of a fingerboard ramp. Ramp
150
includes a base
152
constructed either of plastic as a unitary component or wood of a unitary or multi-piece construction. The ramp
150
includes a number of different riding surfaces, such as platform
154
, inclined ramps
156
,
158
and
160
, which can be of similar or different slopes, and a curved ramp
162
. The ramp also includes a wall
164
on platform
154
and a wall
166
on both platform
154
and inclined ramp
156
. Wall
164
includes a horizontal upper surface on which is mounted a horizontal metal coping
168
. Wall
166
includes an inclined upper surface on which is mounted an inclined metal coping
170
. The walls can be molded as a unitary part of base
152
or can be separate components attached to the base
152
with adhesive, screws, or other known fasteners. The metal copings
168
and
170
can be of one-piece or multi-piece construction and are attached to the respective walls by adhesive, screws or other known methods.
The riding surfaces of the ramps shown in
FIGS. 7-10
can be provided with a smooth surface texture or, more preferably, a patterned surface texture which better approximates the surface texture of a skateboard ramp and thus, offers a more realistic sound, feel and experience to the fingerboarder. The ramps can be painted or coated with other known coatings, such as polymeric coatings, to better approximate full-sized skateboard ramps. The ramps can also be provided with strengthening ribs and support structure as needed to provide a stable structure to the fingerboarder. In the preferred embodiment the ramps have generally hollow bases open at the bottom.
Alternatively, enclosed hollow bases can also be used which are either completely enclosed or which include a sealable opening for accessing the hollow interior. In either the open hollow or enclosed hollow bases, the bases can be filled partially or fully with an additional substance. As shown in
FIG. 11
, a sectional view of one embodiment of the base shown in
FIG. 8
, such a substance can include a rigid foam
176
, for strengthening the base, with ribs
178
provided in ramp
120
to help retain the foam
176
. The foam
176
can also be glued into the base. The foam can also be used in an enclosed base for rigidity.
Alternatively, in an enclosed hollow base, sand, water or another dense substance can be added to the base to provide additional mass and stability to the base. Adding sand, water or other dense substance to the enclosed base also deadens the sound of the base, giving a sound better approximating the sound of a heavily constructed skateboard ramp. See
FIG. 12
which shows a sectional view of an alternative embodiment of the ramp shown in FIG.
8
. By providing a sealable opening
180
in the enclosed hollow base, such as a screw top with a cap
182
located in a recess
184
on the underside of the base, the sand
188
(or water or other dense substance) can be added by the user after purchase of the ramp to save on shipping and packaging expenses for the ramp. Other types of openings and caps can also be provided for access to the hollow interior. The strengthening, stabilizing and mass adding structures just described can also be applied to larger ramps and and full-sized skateboard ramps. Solid or semi-solid bases can also be used.
FIG. 11
also shows the use of rubber or polymeric pads attached to the underside of the base by known methods to provide an antiskid surface to the base. The pads can be located in depressions in the base bottom and have their thickness adjusted as desired to provide a desired engagement between the ramp and the surface it is placed on. That is, the height of the pads is adjusted to provide a desired antiskid effect while minimizing the gap between the ramp surfaces such as
128
and
130
and the supporting surface
190
.
Although the bases of the ramps shown in
FIGS. 7-12
are disclosed to be constructed of plastic, they can alternatively be constructed of other materials such as fiberglass or other fiber reinforced plastic, cast concrete, cast stone, machined wood or even formed, stamped, cast and/or machined metal. In addition, although these bases are preferably constructed as one-piece components, they can also be assembled from multiple pieces, utilizing for instance, the techniques disclosed above with respect to
FIGS. 1-6
.
While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that it is capable of further modifications and is not to be limited to the disclosed embodiment, and this application is intended to cover any variations, uses, equivalent arrangements or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features hereinbefore set forth and followed in the spirit and scope of the appended claims.
