DETAILED DESCRIPTION OF THE DRAWINGS, THE INVENTION AND THE PREFERRED EMBODIMENT

[0025] The present invention is a set of identical or nearly identical rectangular or longitudinally extending building elements or components, units or blocks, making up segments or increments of a constructed together, low to the floor, longitudinally extending and level balance beam. The blocks or longitudinal elements 100 and 150 of FIG. 1 are basically identical to one another. Each such element 100 has a first end with a round, knob-like forwardly extending protrusion 22, having at its lower edge 24, a trough 26, extending from one forward side of the elements 100 and 150 to the other forward side, subtending an angle of about 270 degrees or more and preferably no less than about 180 degrees. The elements have downwardly and outwardly extending or flared (from top surface 40) side walls 42 and 44. These provide increased stability to the elements when resting upon a floor and the outward flare of the side walls also facilitate nesting of one element 100 within another element 150, as seen in FIG. 5A. Small feet 50 and 52 can be provided at the bottom edges of the side walls to increase stability, too (See FIG. 6). These will extend outwardly from the side walls, if provided. The top surface 40 of the longitudinal elements are preferably level with one another although there could be slight or even major variations in the height of the top surfaces 40 with respect to one another for a variety of purposes (fun, training, difficulty of training, play, and game routines or work on the balance beam, etc.). In FIG. 1, the front or knob element of one of the longitudinal elements 150 is the capture element for the rear of a second longitudinal element 100 having its tab (on its rear edge) extending into the trough of the front knob or protrusion 22 of the rearwardly-located longitudinal element 150.

[0026] In the preferred embodiment, the elements 100 and 150 are substantially identical to one another and can rest and nest within one another as seen in FIG. 5A. The front wall, rear wall, and side walls 42, 44 define an interior and hollow cavity which allows the simple nesting of the longitudinal elements, one stacked within and upon the other. Each such element 100 or 150 includes on one of their front and bottom ends 149 a front, curved trough-like area 102 and on their opposed, other or back and bottom ends 151, a downwardly projecting and inwardly and outwardly resilient tab 212 (see FIG. 2) defined by vertical and basically parallel side slits 153 and 154 cut into the rear wall and extending downwardly on the rear or back wall from below the top surface 40 to the bottom edge 155 of each of the elements. The resilient tab 212 is flexible and can be pushed inwardly towards the inside of the cavity of the element and then will resiliently flex back outwardly to its original position, as shown in FIG. 2. The bottom edge of the resilient tab is preferably provided with a U shaped curve which substantially matches the curvature of the trough wo that the tab will fit within the trough and, yet, one longitudinal element will fit within and be able to be rotated within the trough of an adjacent element. That resiliency and flexibility allows for the back or rear end of a first element, with its curved bottom of the tab to be pushed downwardly and into the trough of an adjacent element. The tab of one element will substantially match the curvature of the trough and easily slide into the trough and, yet, the resilience of the tab allows for the two elements to be secured, and, yet, importantly, allows for one longitudinal element to angularly rotate with respect to an adjacent, connected longitudinal element or component to allow for a variety of angular presentations of the top surfaces of the elements, for increased versatility and play/training value.

[0027] The tab of one element is pushed into the trough of an adjacent and second element and then the tab flexes back to hold the elements together in position and, yet, the two longitudinal elements can be rotated about a vertical axis passing downwardly through the top of the connection ends of the elements. This is the basic mechanical connection contemplated by the preferred embodiment. To release one tab of a first connecting balance beam element 150 from being captured and held by the trough of an adjacent balance beam element 100, the top portion of the tab 212 is pushed inwardly towards its cavity and simultaneously the balance beam element is lifted upwardly, This will disengage the two members i.e., allow for the release of the tab from the adjacently-located trough of a second longitudinal component. The tab-in-trough mechanism will hold the two elements together unless and until the elements are intentionally pulled apart as just described. And, yet, as mentioned, while connected together, there is a modest freedom of axial rotation of one longitudinal element with respect to its connected-together second longitudinal element. Stated differently, the adjacent longitudinal components can assume angular orientations with respect to one another and, as an alternative, can be aligned and linear. In addition, the width of the tab element is far less than the angular measure of the trough of the adjacent member into which it can be inserted so that multiple tabs and their longitudinal elements can be attached into a single trough to thereby provide a large number of configurations for the balance beam components.

[0028] The resilient tab 212, when held within the trough, holds the two elements together and, yet, the tab of a first element will allow it to rotate within the trough of a second longitudinal element to allow the angular adjustment, if desired, of one element's length-wise or extending axis or angle with respect to the second length-wise or extending longitudinal axis of the adjacent balance beam element. When two balance beam elements are connected together, with the tab of one fitted within the groove or trough of another longitudinal balance beam element or member, a stable lengthwise construction, with their top surfaces adjacent and level, extending slightly above the floor, is presentedfor play, training, and simple fun- and for walking upon. In one embodiment, as shown in FIG. 6, the top level or surfaces 40 are provided with regular spaced bumps or tactile shapes, which provide a slightly elevated and relatively depressed surface comfortable to the feet of the user and also provide the sole of the foot of a user to somewhat grip the top surface to facilitate walking on the top level or surface 40.

[0029] The blocks or longitudinal elements 100 and 150 may be arranged and connected in any number of configurations, and depending upon the placement of the tabs within the troughs, present an extended balance beam for a youngster to walk and train upon with the axis of the longitudinal elements possibly presented at a variety of angles or, stated differently, with one longitudinal axis of a first balance beam element at an acute, right or even obtuse angle with respect to the second balance beam element and its longitudinal axis. Configurations as set forth in FIGS. 3, 4A, and 4B (and countless others) can be achieved. In addition, the present invention can include, but not necessarily, a set of one or more rest stops or lily pads where the child's two feet can be side by side and rest at intervals. Those rest stops can be circular or octagon or hexagon in shape and, yet, be provided along their bottom edge with trough members for selective acceptance and holding of one or more tabs of the longitudinal elements 100 and 150. This, too, provides unlimited design flexibility to the end use toy product.

[0030] The blocks or longitudinal elements 100 and 150 can easily be joined together, first tab of one balance beam element within trough-shaped bottom end of a second balance beam element, and that second balance beam element and its tab on its other end can be placed and secured within the trough end of yet another longitudinal element. These mechanical connections, tabs within troughs, can continue, element by element to achieve a length of elements in a straight line or with various angles formed by the elements. Then, as mentioned, the tabs can also be retained within a trough component of the rest stop elements, too. Each tab will be inserted (by pushing on the top of the tab and inserting it into the trough of a longitudinal element, then the second tab into a third element's trough, and so on, all to form a longer and/or larger balance beam than a single pair of elements present. The top surfaces 40 of the blocks can be flat and substantially level and/or or provided with the tactile-providing surface (see FIG. 6, elements 610) to help in the training/play of the youngster on the balance beam. The multiple balance beam elements can have their longitudinal axis straight and aligned or the longitudinal axis of one or more of such longitudinal elements can be angled with respect to one another as shown in FIGS. 3, 4A and 4B.

[0031] And, as shown in FIG. 4B as a consequence of the trough of the balance beam elements extending largely circumferentially around the knob or circular bottom end of the same, no less than about 90, preferably about 270 degrees, even more, if desired, more than one resilient tab can be inserted and frictionally held in a single trough of a single balance beam element. Stated differently, a single trough on one knob shaped end of a single longitudinal element can accommodate multiple tabs of several distinct balance beam elements. Thus a wide variety of configurations are available to be built by the user including those where a single balance beam element is a junction point, at its trough end, for two or more resilient tabs of additional balance beam elements (See FIG. 4B, for example).

[0032] The top surface 40 of the blocks 100 and 150 are preferably elevated above ground level only a few inches so that the youngster gains confidence and even if he/she falls off the top surface while playing or training, will not become seriously injured. Each top surface is supported above ground level by downwardly and outwardly extending lengthwise side walls which provide lateral support to the elements and, yet, allow the blocks to nest one within another for compact storage when disassembled. The blocks or longitudinal elements can be disassembled when and if desired and easily nested for compactness of storage.

[0033] The balance beam may be a long continuous extending set of blocks or longitudinal elements or may be presented in other configurations, as an X shape or form a rectangle, for examples, as two or more blocks or longitudinal elements can connect with their tabs of one end secured into the trough on the other end of an adjacent longitudinal element or block or several such blocks. Many configurations and arrangements of the balance beam elements are possible, some as described below and shown in the drawings, for training and play purposes.

[0034] The balance beam, when assembled, is intended for children's play time and may be used by children to imagine different scenarios such as pretending and/or training to be an Olympic athlete, a tightrope walker, circus performer, or walking over water or lava. Children may also use the balance beam to create physical challenges (walking over lava, crossing streams, etc.) or as obstacle courses, for themselves and/or friends. Timed games can be provided, too. Further still, children may simply use the balance beam to enjoy the novelty of balancing and walking on an elevated but safe surface. The balance beam may be part of an indoor playroom or nursery, an outdoor playground, or any other suitable setting.

[0035] The balance beam may also be used in a physical therapy or gym class setting, teaching children or others to balance (with or without holding something in their hand(s) or arms), walk intentionally, and/or to maintain stability. An instructor or physical therapist may incorporate the balance beam in diagnostics or therapy itself. The balance beam created through the connecting longitudinal blocks described herein is reminiscent, or an introduction, to, a standard piece of gymnastics equipment, a balance beam, which requires great skill and practice to master and is not something to be tried unless sufficient skill at a low to ground elevation or level is first obtained. The present invention is intended to reduce the level of fear and/or anxiety in training for a full height or standard balance beam device normally elevated several feet above floor level.

[0036] The blocks or longitudinal elements are connected (resilient tab pressed into trough) to form the extended length of a balance beam using a mechanically connecting front trough of a first longitudinal component which accepts the tab or notched-out mechanism of a second, adjacent longitudinal block or element. The placement of the tab within the trough is secure as a consequence of the outwardly and inwardly-directed resilience of the tab within the trough and, yet, the tab and its longitudinal element can be rotated within the trough of another longitudinal element to present the two secured longitudinal elements in a variety of angular configurations. This tab-within-trough holding mechanism, described in detail and shown in the Drawings, ensures a secure connection which prevents inadvertent and premature or unintended disassembly for maximum safety. The mechanism still, however, may be simply engaged or disengaged when desired to promote easy set up, clean up and, as mentioned, the flexibility or angular variety which can be achieved, as desired for the angular positioning of the adjacent blocks or axis of the longitudinal elements. The mechanism involves only one simple movement to engage or disengage such that a child may build, use and disassemble the blocks and balance on his or her own. The tabs easily flex into and then similarly flex outward, when released to hold the tabs within the troughs and, likewise, can be depressed to flex inward and one longitudinal member released from the trough of a second longitudinal member.

[0037] The blocks preferably include, on one end, a trough forming a curved and knob-like end, and on the other end, a downwardly extending, inwardly and outwardly flexible or resilient tab. The tab can be compressed inwardly and slid down into the trough of a second block for a mechanical interlock which can be disassembled as and when desired by a simple new inwardly pressing of the tab to disengage the same from the trough or groove of the adjacent longitudinal member. To accommodate interlocking, the curved ends of tab and trough will have curves of similar radii of curvature and dimensions. The curved bottom edge of the tab of a first longitudinal element will mate with and into the trough of a second end of a second longitudinal element and will be holdable or mechanically linkable to that second longitudinal element or block. As such, each block, in a preferred embodiment, includes both a trough and a tab at their opposite ends. When a first block interlocks with a second longitudinal block, the curved end or tab of the first block interlocks with the curved end of the trough of another block. This is accomplished by the tab of a first block fitting downwardly and into the trough of a second block. This connection creates a stable balance beam structure from the two blocks and also allows for a wide variety of angles between the members as the trough extends substantially around one end of the curved knob of the first longitudinal members or blocks and the tabs of the other end of the other longitudinal members can define angular projections that are far less than the trough defines so that one trough of a first element can accommodate many tabs of several other longitudinal elements. The tabs can slide within and laterally adjust and move within the trough of the second longitudinal element to present a wide variety of configurations of the longitudinal elements.

[0038] Two substantially identical longitudinal elements or blocks 100 and 150, as connected together, are shown in FIG. 1. The rearward tab of the forwardmost longitudinal element 100 is slid into and engages the trough of the rearward longitudinal element 150. Two elements are partially shown and enlarged (and separated) in FIG. 2, with block 150 (now the forward longitudinal element) including a first rearwardly located curved knob end 102 with trough 103 and, on its other end (not shown) having a front end with a slightly curved end tab. The second longitudinal element 100 (now the rearward located longitudinal element 100) has a downwardly projecting, front end of the block, tab 212 (shown in FIG. 2 on the second block 100). One block includes a curved knob-like end 152 and an edge-surrounding trough 153 and a second block has an inwardly (or concave-like) curved end 154 and a downwardly projecting tab defined between the two slits 153 and 154 fits into the trough of the second longitudinal element. A first block 100 may mechanically connect to identical second block 150 when end 104 (see FIG. 1) and its downwardly projecting tab interlocks with and into the trough of end 152 of the other longitudinal element 150, and the tab 105 interlocks within trough 153, to create one continuous longitudinal structure, a balance beam, comprising blocks 100 and 150. FIGS. 1 and 2, show a two block construction but, of course, the length of the balance beam can be extended by merely connecting more blocks, tabs into troughs of additional blocks. And, as the troughs are curved for a greater circumferential extension than that required for only the width of single tab, a second block with its tab in the same trough of the first block can be angularly positioned with respect to the longitudinal axis of the trough-providing block, as desired. This allows for a variety of angular configurations. And, as mentioned, since the trough is greater than the width of the single tab, more than a single tab can be inserted and held into a single trough for providing greater variations and configurations.

[0039] While the preferred embodiments present two curved ends, one concave (with the downwardly protruding curved tab formed at the bottom end by the parallel slits separating the tab from the rest of the wall) and one convex (defined by the know-like end with the upwardly extending trough at its base edge) such as for example ends 102 and 104, other embodiments may not require such a detail. For example, one end, such as the end with the tab, may be itself angled. However, it should be noted that having two mating ends (tab within a trough) of the longitudinal elements tend to maximize the area of extended walking surface 120. And, correspondingly, opposed ends of some of the longitudinal elements may be flat (not provided with trough nor tabs) thereby having some elements present flat terminal ends. Alternative embodiments may create gaps between the blocks 100 and 150 which, however, increase the risk of a misstep and ultimately a fall or, as should be appreciated, will require more skill and concentration to walk upon the multiple lengthwise constructed blocks.

[0040] FIG. 2 shows an enlarged view of two closely yet unconnected blocks of the connector mechanism 200 of the most basic of a balance beam set 250. A forwardly located block 220 includes a rear and curved knoblike or convex end 202 with a trough 204 at its base which is circumferential around the end (i.e., it basically describes a circular footprint). At the base edge of the circular end 202 is a trough 204 for receiving the tab 212 of a second block 100 (which is the identical in overall shape as the first block, just turned around with its trough extending rearwardly away from the trough of the first block). The trough 204 will receive and hold the resilient tab 212 (flexible inwardly towards the longitudinal axis of the block and then flexes, when released, back out to its original position) of the second block 100. A short height wall 208 of the outer circumference of the trough 204 serves to hold the tab 212 of the second block in place and defines the outer edge of the trough. Due to the curved (concave) shape of tab 202, and convex shape of the trough 204 and the flexibility and resiliency of the tab, the two elements will be secured for use as a balance beam. The circumference of the trough increases the range of motion possible when trough 204 is engaged by the tab 212 because the tab(s) may be engaged at any point along the angular circumference of the trough. Because of the many possibilities of engagement points, the trough allows for many degrees of connection, and therefore block 220 may connect with several tabs of other blocks at a wide variety of angles. These possibilities create opportunities for many different arrangements of balance beam set 250. In preferred embodiments, the trough 204 defines a substantial curve to allow for at least and likely more than 180 degrees of connection for one or more longitudinal elements.

[0041] The front face of the back element or component 100 with the tab 212 is, in preferred embodiments, concave in shape so as to align with the circular nature of the trough end 204 of another block 150 (i.e., the circular knob corresponds with the curved upper portion of the tab) so that they easily rotate with respect to one another. However, in alternative embodiments, one end 210 may include other and simple shapes, such as a narrow tab, a similar configured trough but smaller in dimension, and/or a pin, still capable of connecting into and with trough 204.

[0042] FIG. 3 shows an example arrangement 300 of six blocks 220 in a non-straight line. Each block 220 includes a circular, knob-like front end 202 and concave tab or back end 210. Each block 220 further includes a trough 204 and an opposed tab 212.

[0043] FIGS. 4A and 4B show alternative arrangements 400 and 450 of the same blocks 100 and 150 or longitudinal elements 220. Arrangement 400 shows a wide range of angles available for connecting blocks 220. For example, a 135 degree angle is illustrated at point 401, a 170 degree angle is illustrated at point 402, and a 175 degree angle is illustrated at point 403. As mentioned with regard to FIGS. 3, 4A and 4B, the connections may also be any other angle between 90 and 270 (or maybe more) degrees.

[0044] Arrangement 450 of FIG. 4B, shows one preferred embodiment of the balance beam set in which multiple blocks 100 and 150, here labeled 451 and 452, may connect to a single previous block, labeled 453. While several designs may allow for such a feature, the design circumference) of the groove 204 of circular portion of front end 202 and the relative length of the tab(s) 212. That is, the groove of 453 is long enough to accommodate more than one tab 212. As seen in other example embodiments, multiple angles of connection can be constructed as well.

[0045] In one preferred embodiment, the blocks 220 (100 and 150) are stackable for easy storage. Such an embodiment is shown in FIG. 5A, in which two sets of five identical blocks 220 form two stacks 500. In the illustrated preferred embodiment, the blocks 220 are hollow with an open downwardly extending base 530. That is, the blocks 220 have a top walking-upon surface and supporting side walls (preferably four, in rectangular embodiments although the shape and number of side walls may vary), but no bottom surface. This provides a hollowness to the blocks. In some embodiments block 220 includes internal structural supports to accommodate and strengthen the hollow nature. The blocks 220 also include outwardly flared side walls 510 which meet the top surface 520 at an angle larger than ninety degrees. Accordingly, the surface area of top surface 520 is smaller than the surface area encompassed by the base 530 of the block 220. This feature is shown in greater detail in FIG. 5B, which shows a top view of a single block 220. Top surface 520 is shown surrounded by base 530 at this viewing angle. The flared nature of the blocks 220 allow for easy stacking, and ultimately tidy and compact storage. It should be noted that the circular front end 202 should also include flared side walls for facilitating stacking.

[0046] In a preferred embodiment, as shown in FIG. 5A, the blocks 220 are sold as a set including, for example, 3-20 identical or nearly identical blocks 220. The set of multiple blocks 220 ensures that a user may create a lengthy balance beam on which to maximize balance and/or walking practice. In some embodiments, the set may not include identical blocks 220 but instead include one or more specialty blocks such as a block of a different shape (round, zig-zag, curved, squiggly, angled, etc.), surface texture, height, color, or style. In some embodiments the blocks 220 may be identical in structure but vary in color or other design elements.

[0047] FIG. 6 shows an example of a block 600, such as block 220, in a preferred embodiment with surface designs. In the preferred embodiment shown in FIG. 6, top surface 601 includes low protrusions 610, arranged in a fun design appealing to children. The low protrusions 610 serve both the purpose to decorate the block 600 in a child-appealing manner, and the purpose of creating a grip contour to prevent users' feet from slipping and sliding on top surface 601. Low protrusions 610 may take many forms and shapes. They may, as seen in FIG. 6 create an appealing design. In one embodiment, the low protrusions 610 may create one uniform pattern, such as polka dots, stripes, or waves. In another embodiment, the low protrusions take the form of a sensory toy, with a pattern intended to appeal to a user's sense of touch and that, in turn, may tell a user, without looking down onto the beam, where he/she is along the length of the beam. In one embodiment, the low protrusions 610 may be the same material as the block 600. In another, they may be rubberized material, foam consistency, or any other suitable texture. In one embodiment, the low protrusions 610 may rise only one or two millimeters from the top surface 610. In one embodiment they may rise considerably to create a more tactile effect.

[0048] FIG. 6 also shows block 600 with feet 620. These feet 620 are connected to or molded with and into the base of block 600 and prevent block 600 from slipping and/or sliding on the flat floor surface 602 on which block 600 is placed, such as a floor, sidewalk, or mat. Feet 620 may, in one embodiment, be made of a rubberized or other anti-slip material. Such materials create additional friction against the surface 602, which helps keep block 600 in place. Feet 620 may take many forms. In one embodiment, feet 620 may extend around the entire perimeter of block 600 that makes contact with surface 602. In one embodiment, feet 620 are placed intermittently along that perimeter as seen in FIG. 6. Feet 620 may also take the form of an appealing design in some embodiments such as that seen in FIG. 6. Feet 620 may also take a functional yet aesthetic form in some embodiments, i.e., in the shape of actual small feet or small semi-circular arcs.

[0049] In a preferred embodiment, the block 600 is of a width appropriate for a child's foot, such as approximately four inches wide, although deviations may exist without impacting the intended purpose. The block 600 in preferred embodiments is of a minimum height to be visually and conceptually raised off the surface 602, roughly two, four and even up to six inches high. At such a height, a user must balance to walk across the block 600, but, in the event of a misstep, will not fall from a dangerous height. Length of the block 600 may vary, although, in preferred embodiments, the block 600 is of a length to accommodate at least one step of a child's foot and preferably is about 2 to 3 feet in length. The block 600 is made of any sturdy material, such as stiff plastic or wood, capable of holding the weight of a child. The block 600 may come in a variety of colors and designs. In one embodiment, each block 600 of a set is of a different color or design to distinguish each block and create a fun, child-like, appearance and atmosphere. Such colors or designs may also be used to, for example, instruct a child or playmate to reach a particular block 600, as in a game (for example, a child might, during play, instruct another to jump to the red block or spin around once when you get to the green block).

[0050] In preferred embodiments, the top surface 601 is largely flat, as seen in FIG. 6. However, some embodiments may deviate from this design. For example, in some embodiments, top surface 601 may include an incline or decline or waves along its longitudinal axis. It may also have a bumpy surface. It may include features such as steps as well or mimic natural terrains such as a rocky mountain surface or pebbled beach surface.

[0051] FIG. 7 shows a cross section of the trough 204 and tab 212, when secured or interlocked. As shown, tab 212, when interlocked, is placed into trough 204 and the position is maintained by frictional and resilient engagement. The inside of the trough may be grooved to more securedly hold the tab in place and prevent or minimize the tab from slipping out of the trough. This tends to ensure a secure attachment and ultimately safety.

[0052] However the simplicity of both the tab end and the trough end allows two blocks 220 to become interconnected with one simple downward motion placing the tab 212 into the trough. This simple motion can be performed by a small child, as no complicated locks or latches are involved. Similarly, the blocks 220 may be separated by merely depressing the tab inwardly and lifting the block of the tab upwardlythat is. usually lifting the block with the tab out of the trough of the other block. This motion may be also be performed by a small child. The simplicity of the processes to connect and separate the blocks allows for independent child play as well as easy assembly and disassembly regardless of age or strength of the user.
