This is a continuation-in-part patent application of copending application Ser. No. 12/683,909, filed Jan. 7, 2010, entitled “MARBLE TRACK AMUSEMENT DEVICE”, which claimed one or more inventions which were disclosed in Provisional Application No. 61/204,896, filed Jan. 31, 2009, entitled “WALL COASTER” and Provisional Application No. 61/277,241, filed Sep. 23, 2009, entitled “WALL COASTER”. The benefit under 35 USC §119(e) of the United States provisional applications is hereby claimed, and the aforementioned applications are hereby incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention is directed to an entertainment device including a track for rolling marbles. It may be set up on either one or more two-dimensional or three-dimensional surfaces, or combinations thereof, where the path the marble traverses may include open-air trajectories.
BACKGROUND OF THE INVENTIONA conventional marble track toy, known as Blocks and Marbles™ is manufactured by Tedco, Inc. (Hagerstown, Ind.) and a similar product, called Amaze-N-Marbles™, was once manufactured by T-N-T International, Inc (Waco, Tex.) D/B/A “Toy-N-Things”. The design of these toys includes cubes which have an internal marble channel with right-angle turns through it, and rectangular blocks which have an exposed trough for the marble to roll along. The cubes are constructed having one section of the channel oriented vertically, with an opening at the top of the cube widened to facilitate capture of a falling marble. The marble track is constructed by stacking the cubes and rectangular blocks such that a marble dropped into the interior channel of a cube near the top of the track, or rolled along a trough in a rectangular block near the top of the track, will pass through a sequence of interior channels and troughs as it descends along the track.
A disadvantage of this construction is that cubes and rectangular blocks from the construction set are used to support other cubes and rectangular blocks that form the marble track, thereby limiting the overall length and height of the marble track. Another disadvantage of this design is that the positions of the cubes and rectangular blocks are limited to points on a three-dimensional grid to provide the necessary alignment of the pieces of the construction set.
U.S. Pat. No. 5,007,876 discloses a marble track consisting of track segments having a variety of geometries, including curved track segments, track segments for launching the marble into mid-air trajectories, and track segments for catching the marble from mid-air trajectories. Each track segment includes a cylindrical stacking element which may be removably inserted into the cylindrical stacking segment of another track segment, thereby limiting the heights of the track segments to multiples of the cumulative heights of the cylindrical stacking elements.
U.S. Pat. No. 4,171,090 discloses a marble track that contains a pair of flexible elongated rods that are supported on a horizontal surface by support poles. The support poles are inserted into holes in a base plate which are located at positions on a two-dimensional grid. Although the heights at which the flexible elongated rods are attached to the support poles can be adjusted, this track does not permit mid-air trajectories of the marble.
Swedish Patent No. 47513 discloses a marble track consisting of track dowels and cubic blocks having channels therethrough. The channels through the cubic blocks have widened mouths into which the ends of the track dowels rest. Since the track dowels are of fixed lengths, the cubic blocks must essentially be separated by the lengths of the track dowels. This marble track does not include any components which can launch the marble into a mid-air trajectory.
U.S. Pat. No. 1,252,616 discloses a marble track consisting of chutes which are supported on a horizontal surface by pins. These pins are inserted through bores in support rods which are, in turn, mounted in base blocks. The bores are spaced at regular intervals along the support rods and the bottoms of the chutes have downward projections to prevent the chutes from sliding off the pins. This design limits the number of orientations of the chutes as well as the height of the track.
U.S. Pat. No. 6,056,620 discloses a marble track consisting of chutes, bumpers and pivoting systems that allow the marble to travel through the air from one chute to the next. This patent discloses that the track is mounted on a vertical surface. This patent also discloses the use of magnets to adhere the chutes and other components to vertical paramagnetic or ferromagnetic surfaces.
SUMMARY OF THE INVENTIONA marble track amusement device includes track elements which are removably attachable to both vertical and horizontal planar support surfaces. The device is not limited in height by the number or size of the components. It contains elements that provide for mid-air trajectories of the marbles which are not limited in height by the number or size of these elements. The marble track amusement device is not limited to arrangements on three-dimensional, two-dimensional, or even one-dimensional grids. The three-dimensional orientations of the components are infinitely adjustable.
The track elements are not required to support and/or stabilize each other and, in preferred embodiments, the structural track elements do not directly contact each other. They only function to control the path of the marble, thereby substantially increasing the variety of track geometries and facilitating the ease of assembly, disassembly and replacement of track segments.
The track can be configured to accommodate variable mid-air trajectories. This requires highly precise positioning of the individual track elements. The marble track amusement device preferably includes any combination of chutes, re-directors, stairs, catapults, loops, funnels, ¼ circles, ½ circles, ¾ circles, full circles, rail systems, alternating elements, peg elements, and other kinetic pivoting components, all of which may be removably attached to a substantially planar support surface.
As shown in
Further, the marble track 100 may be mounted onto multiple alternating horizontal and vertical planar support surfaces 180. Exemplary support surfaces 180 include, but are not limited to, refrigerator doors and walls, doors, table tops (or a combination of a table top and adjoining legs), chair legs, floors, windows and vertically or horizontally oriented rod-like structures, including tree limbs, such as those found on a Christmas tree. Depending upon the types of surfaces upon which the structural elements are going to be placed, the user can utilize more than one type of mounting or attachment element. For example, if a first vertical surfaces is a window, a table top is a first horizontal surface, and a Christmas tree branch is a second horizontal surface, one could use putty or suction cups for the window, putty for the table top and clamps for the Christmas tree branch.
The embodiments of the present invention enable the structural elements to be reversibly attached to two or more different types of surfaces to provide a path for a marble to travel. For example, the highest structural elements could begin on a window, with additional structural elements on a table top, and other structural elements on lower Christmas tree limbs and a trunk of a Christmas tree. The structural elements in this example could be placed such that the marble travels through the structural elements on the window, through the structural elements on the table top, through structural elements on one or more of the lower Christmas tree limbs and finally through the structural elements on the Christmas tree trunk.
While none of the structural elements in
While the structural elements are preferably reversibly affixed to the planar support surfaces using an attachment element, in other embodiments, one or more of the structural elements may be hung from a surface, such as a ceiling or another support surface, by string, bands, or another material that allow the structural elements to be placed to create a path for one or more marbles.
Each chute element 120 has a specially designed rim or ridge 121 on each end to assist with attachment to the supporting surface. The ridge 121 is an integral part of the chute element 120 and preferably extends along the entire length of each chute element 120. The attachment element, for example re-usable putty, is preferably applied above the ridge 121. The ridge 121 pushes against the planar support surface 180 when the chute element 120 is affixed to the planar support surface, to retain the shape of the chute element 120 and keep the chute portion of the chute element 120 from pushing against the planar support surface 180.
Each re-director 130 has at least one integral tab 131 that provides a surface area which the attachment element uses to adhere the re-director 130 to the support surface 180. Each of the stair elements 150 has at least one integral tab 151 that similarly assists with adherence to the support surface 180. The re-director 130 acts to move the marble quickly in a direction that is opposite from the direction that the marble was originally traveling (e.g. a 90 degree change in direction, from substantially horizontal to substantially vertical, in
Since track elements 120, 130, 140, 150 and 160 may be mounted on almost any surface, the positions to which these track elements can be set are essentially infinitely variable. Configuring a marble track with open-air trajectories generally requires trial-and-error positioning of the track elements 120, 130, 140, 150 and 160 to insure that the marble 170 will be properly “caught” by each track element 120, 130, 140, 150 and 160 in succession along the track. For example, when the marble 170 is put in a left downward sloping chute 120a, the marble will roll from left to right as the left side of the chute is lower than the right. The marble 170 will travel over the rim 121 of the chute 120a and be caught by a second chute 120b, shown in
The infinite adjustability of the positions of the chutes 120, the re-director 130, the tube 140, the stairs 150 and the funnel 160 allows the user the satisfaction of fine-tuning the orientation of the track 100 so that the marble 170 consistently completes the track. This also allows the user to construct extremely challenging marble tracks having diverse mid-air trajectories requiring precise positioning. Further, since the structural elements 120, 130, 140, 150 and 160 can be positioned to direct the marble 170 along a significant variety of paths and trajectories, the vertical and horizontal positioning of these elements is not restricted to locations on only a one-dimensional or two-dimensional grid. Also, since the track elements are attached directly to the support surface, rather than being in contact with each other, the course the marble takes is only dependent on the track geometries and the positioning of each of the structural elements. There is thus a substantial increase in the variety of track designs. This flexibility also makes the marble track amusement device easy to assemble, disassemble and replace or adjust portions of the track.
While the funnel structural element 200 may be of any dimensions to work with the other structural elements in the device, in one preferred embodiment, the funnel structural element 200 is approximately 3.5 inches wide at the top opening 202 and is approximately 3 inches long from the top opening 202 to the bottom opening 203. The bottom opening 203 can be of any dimension capable of permitting the exit of the marble.
The half circle structural element 300 has many uses. When the opening 302 is placed facing an oncoming marble 170 (as shown in
The half circle structural element 300 may also be used as an “end” piece to hold the marbles 170 when they reach the end of the run, as shown in
In some embodiments, the marble 170 enters the bottom 404 of an angled ¾ circle and exits the top 405. In other embodiments, a marble 170 enters the top 405 of an angled ¾ circle and exits the bottom 404. Changing the orientation of the opening 402 changes the trajectory of the exiting marble. Multiple ¾ circle structural elements 400 can create a looping system. To create a looping system, a first ¾ circle structural element is placed to accept a marble at the top 405 of the ¾ circle structural element. A second ¾ circle structural element is placed with the opening 402 of the second ¾ circle structural element facing the opening 402 of the first ¾ circle structural element, but located slightly below and offset from the bottom 404 of the first ¾ circle structural element so that it catches the marble exiting the bottom 404 of the first ¾ circle structural element. Additional ¾ circle structural elements can be placed so that a series of ¾ circle structural elements guide the marble along a looping path. In another embodiment, the looping system can be created with the marble entering each of the ¾ circle structural elements from the bottom 404 and exiting the top 405, or alternatively, the marble can enter some of the ¾ circle structural elements from the bottom 404 and others from the top 405. Similar looping systems can be created with the ½ circle structural elements 300 discussed above.
The ¾ circle structural elements 400 can also be used in the various ways discussed with respect to the ½ circle structural element 300. When the opening 402 is placed facing an oncoming marble 170 (similar to what is shown in
The ¾ circle structural element 400 may also be used as an “end” piece to hold the marbles 170 when they reach the end of the run (similar to what is shown in
The half circle structural element and/or the ¾ circle structural element (as well as all of the other structural elements described herein) may be of any dimensions that can create an effective path for a marble. In one example, the half circle structural element and the ¾ circle structural element are approximately 2.5 inches in diameter and approximately one inch deep.
In order for marbles 170 to travel into or through the full circle structural element 500, the full circle structural element 500 preferably includes at least one hole 502 in the upper portion of the curved portion 508 and at least one hole 502 at the bottom of the curved portion 508 of the full circle structural element 500. In one embodiment, as shown in
In other embodiments, the full circle structural element 500 can be placed such that the marble 170 hits a curved portion 508 of the full circle structural element 500 such that the full circle structural element 500 acts like a bumper. In yet other embodiments, the full circle structural element 500 can be angled such that a marble 170 enters the full circle structural element 500 at the end of the track. In this embodiment, none of the holes are aligned for the marble to exit the full circle structural element.
The ¼ circle structural element 600 changes the trajectory of the marble when the marble enters the ¼ circle structural element 600 at one end 603, travels along the ¼ circle structural element 600, and exits the other end 604 of the ¼ circle structural element 600. The ¼ circle structural element could also be oriented so that the marble enters at end 604 and exits at end 603. Because the ¼ circle structural element 600 has a relatively short track length, the trajectory change is smaller than for many of the other structural elements. In some embodiments, the ¼ circle structural element 600 acts as a re-director, changing the trajectory of the marble approximately 90 degrees, similar to the re-director 130 shown in
The three pronged body 902 is preferably connected to a support section 904, as shown in
Although
The elements 120, 200, 300, 400 and 500 are preferably reversibly affixed to the vertical support surface 1202. The chute elements 120 supported by L-shaped brackets 1203 are reversibly affixed to the horizontal portion of the L-shaped bracket, and the vertical portion of the L-shaped bracket, which contacts the vertical support surface 1202, is reversibly affixed to the vertical support surface 1202.
In some embodiments of the marble track amusement device, some of the structural elements are attached to a substantially vertical support surface, such as a conventional wall, while other structural elements are attached to a substantially horizontal support surface, such as a table. This allows the marble 170 to travel on both vertical and horizontal planes. In a variation on this embodiment, an “L” bracket (see e.g. the L-brackets 1103, 1203 or a re-director (see. e.g. re-director 130 in
An example of these embodiments is shown in
The L-shaped brackets discussed with respect to
In other embodiments, all of the structural elements are attached to one or more substantially vertical planar support surfaces. In still other embodiments, all of the structural elements are attached to a substantially horizontal planar support surface.
The overall length and width of the track is only limited by the dimensions of the support surfaces and the strength of the elements that attach the track element to those surfaces. Similarly, the dimensions of the track portion of each structural element are limited only by the size of the marbles to be used in a particular device. In fact, structural elements may be manufactured to accept marbles of various sizes. In addition, a track element may take the form of a trampoline, a water wheel-type mechanism or a catapult which can launch the marble 170 onto or into another structural element. Also, since the various track elements can be mounted on planar surfaces with a 360° freedom of orientation they can serve multiple functions. For instance, the bottom of a chute can function as a bumper, or two chutes mounted side by side can allow two marbles to race.
The structural elements of the marble track may be constructed of any material, including, but not limited to, plastic or metal materials. Each element may be made of a pliable elastomeric material, or a rigid substrate may be coated with an elastomeric material to cushion the impact of the marble with a specific track element, thereby decreasing the likelihood that the marble will bounce off the track. The elements can be constructed of the same or different materials as each other. The cross-section of a track element may be altered to better trap a falling marble. The marble track device may include mechanical or electromechanical elements for raising the marble to the top of the track once it has reached the bottom of the track. It may also include electrical or mechanical elements for generating sounds or noises when triggered by contact between the marble and selected structural elements.
The structural elements of the marble track may be manufactured in any color. In preferred embodiments, at least one of the structural elements is manufactured in translucent colors so that the user can see the marble move through the structural elements. Any or all of the structural elements may be manufactured in translucent colors.
Accordingly, it is to be understood that the embodiments of the invention herein described are merely illustrative of the application of the principles of the invention. Reference herein to details of the illustrated embodiments is not intended to limit the scope of the claims, which themselves recite those features regarded as essential to the invention.
