Abstract
A toy vehicle ramp has a resiliently flexible sheet panel and a pair of stiffer support members. Each support member has a plurality of support points formed thereon arranged to define a channel in which a lateral edge portion of the sheet panel is slidingly received for height adjustment of the panel in the supports and thus of the ramp. One or more elastic members extend between the support members and beneath the sheet panel to hold the ramp together. The flexible sheet panel collapses and the band(s) stretch when a load heavier than an ordinary remote control toy vehicle is applied so that a child cannot jump from or ride over the ramp and so that the ramp can collapse without damage to its components for reassembly and reuse.

DETAILED DESCRIPTION OF THE INVENTION




Referring to the drawings and particularly to

FIG. 1

, a preferred embodiment of the toy vehicle ramp


10


of the present invention is disclosed. A resiliently flexible sheet panel


20


is provided as the jumping surface for the ramp


10


. Two support members


30




a


,


30




b


are shown. Each support member


30




a


,


30




b


has a plurality of support points


40


which, in the preferred embodiment, are in the form of tubular stems extending from the support members


30




a


,


30




b


(stems


40


of support member


30




a


shown in FIG.


2


). The support points


40


are preferably positioned (e.g. staggered) along an inner surface of the support members


30




a


,


30




b


such that the support points


40


effectively define a channel configured to receive therein and slidingly contact a lateral side edge of the sheet panel


20


.




The sheet panel


20


is preferably a flat, thin sheet made out of resiliently flexible material, such as polypropylene plastic or the like, so that the sheet panel


20


can be bent to provide a curved ramp surface when inserted in the channels defined in the support members


30




a


,


30




b


and can non-destructively collapse and rebound under relatively modest load for safety.




The support members


30




a


,


30




b


are preferably generally triangular in shape and are preferably made of a more resilient/less flexible molded plastic material than the material of the sheet panel


20


such as ABS (acrylonitrile butadiene styrene). It will be understood that the support members


30




a


,


30




b


can be made of various materials and can be formed in a variety of shapes to provide support for the sheet panel


20


. Although the preferred embodiment shown in the figures includes two support members


30




a


,


30




b


, each of the support members


30




a


,


30




b


may be formed as one or more separate or integral parts.




The support points


40


, although shown in the preferred embodiment as tubular stems, may alternatively comprise tabs, slotted projections, studs, shaped surfaces or the like, positioned to form a channel for receiving the sheet panel


20


and indicated, for example, by broken line


32


in FIG.


3


. Further, the channel for receiving the sheet panel


20


may be formed on any surface of the support members


30




a


,


30




b


above their bottom surfaces. For example, the channel alternately could be defined by a curvilinear slot with continuously opposing side edges or with spaced and/or staggered lengths of side edges to define such slot, with or without undulations or one or more protrusions transverse to the length of the slot designed to generate a frictional force on one or both major sides of the sheet panel within the channel to prevent overly easy sliding movement of the sheet panel along each channel.




One or more elastic members such as elastic bands


50


shown in

FIG. 3

, are provided to connect the support members


30




a


,


30




b


. The elastic band(s)


50


extend between the support members


30




a


,


30




b


, and extend beneath the sheet panel


20


when the sheet panel


20


is inserted in the channels of the support members


30




a


,


30




b


. The elastic band(s)


50


provide support for the sheet panel


20


and provide an inward force on the support members


30




a


,


30




b


. The inward force on the support members


30




a


,


30




b


holds the support members


30




a


,


30




b


against the side edge portions


20




a


,


20




b


of the sheet panel


20


. Appropriate slots


42


are provided to define studs


44


in the plane of the support members


30




a


,


30




b


around which each band


50


is looped. In the depicted embodiment, two identical bands are used, extended between the lower two pairs of studs


44


. It is suggested that the elastic members


50


be located at the lower end of the ramp to best absorb the impact and direction changing forces applied to the ramp by the toy vehicle(s) using the ramp.




As shown in

FIG. 1

, when the sheet panel is inserted into the support members


30




a


,


30




b


, the sheet panel


20


is slidingly engaged by the support points


40


of the support members


30




a


,


30




b


. Side edge portions


20




a


,


20




b


of the sheet panel


20


are engaged within the channels defined by the support points


40


on the support members


30




a


,


30




b


. The height of the ramp


10


may be adjusted by adjusting how far the sheet panel


20


is inserted into the support members


30




a


,


30




b


. The upper and lower edges


22


,


24


, respectively of the side panel


20


are shown in solid in

FIG. 1

in the most elevated position of the sheet panel, while a possible lower position of those edges are indicated by broken lines


22


′,


24


′. The ease of movement of the sheet panel


20


along the channels is controlled by the tension of the elastic band(s)


50


. Alternatively or in addition, ease of movement of the sheet panel along the channels could be controlled by increasing the contact area(s) between the support points or other structure(s) defining the channels and the edge surfaces of the panel


20


contacting those structures or the degree the edge portions need to deflect back and forth to weave their way through the supports.




The ramp


10


is preferably designed to be used for a variety of toy vehicles. The ramp


10


is also preferably designed to be collapsible. The collapsible feature is provided to prevent injury to users attempting to jump off of the ramp


10


on, for example, a skateboard, bicycle, or the like, and to prevent damage to the ramp


10


in the event that it is stepped on or otherwise forced to collapse. As shown in

FIG. 4

, the sheet panel


20


, the support members


30




a


,


30




b


, and the elastic band(s)


50


are designed to coact to allow the ramp


10


to collapse when anything heavier than a relatively light pre-determined weight is placed on the ramp


10


. The predetermined weight is, for example , a weight greater than an ordinary R/C vehicle or other unridden toy vehicle which could fit on the ramp, but less than the weight of a toddler or young child, that might try to walk or ride on a toy directly or partially over the ramp. With two supplied elastic bands


50


, and an approximately eighty thousandths (0.080 or {fraction (5/64)}) inch thick sheet of polypropylene, the depicted ramp


10


is configured to support a weight of at least five pounds and to begin to collapse under a static weight of less than ten pounds, preferably somewhere in a range of about six to about eight pounds and to fully collapse to the position depicted in

FIG. 4

at a weight of about twenty pounds or less. It will also be appreciated that in a collapse, the sheet panel can pull out of either or both support members. The construction permits collapse to occur without damage to the components and with an easy reassembly of the ramp.




It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. For example, it will be appreciated that other types of elastic members such as tension coil springs, elastic tubing and others might be substituted for conventional elastic bands


50


to resiliently yet releasably hold the support members together on either side of the sheet panel


20


. Also, one heavier stronger elastic band could be stretched between two pairs of studs on the support members. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
