## Title
Suction cup teether toy

## Abstract

The present invention relates to a new type of suction cup toy for children and associated methods of use thereof, and, more particularly, to a teether, a play toy, a construction toy, and/or a combination teether and toy.

## Background
FIELD OF THE INVENTION
The present invention relates to a new type of suction cup toy for children and associated methods of use thereof, and, more particularly, a teether, a play toy, a construction toy, and/or a combination teether and toy.
BACKGROUND
Previously, suction cups have been used to secure items to surfaces for a variety of purposes. For example, U.S. Pat. No. 3,677,951 discloses a self-anchorable composite item using suction cups disposed on a single side thereof. Similarly, U.S. Pat. No. 3,101,567 discloses a vacuum cup holding device with suction cups disposed on opposite sides of the device. Devices such as these have been used, for example, to removably secure a bar of soap to a wall in a shower.
However, these devices are not designed for children to play with, and may pose a significant risk to a child. These devices may be made from toxic or other harmful components that could injure or poison a child if the devices were placed in a child's mouth or chewed on. These devices may pose a choking risk for a child, as they could become lodged in a child's mouth or throat and prevent the child from breathing. Further, the devices may be easily broken or torn apart and create a safety hazard, as a child may ingest pieces of the device. Finally, such devices are optimized so as to remain attached to a surface or an object for prolonged periods of time. Thus, a child may have difficulty removing these devices from a surface or object.
Teethers may provide many benefits to a teething child. Chewing on a teether applies pressure and pulls on the gums and teeth, which can both strengthen the gums and/or clean the teeth. This pressure may also relieve pain caused by teething and assist in the growth or development of a child's teeth. Further, the use of a teether may provide psychological benefits by giving the child an activity that exercises his or her mouth, thereby soothing the child.
A toy may also provide many benefits to a child. A toy may be used to entertain a child or provide the child with enjoyment. Further, toys may be educational, assisting a child in learning basic spatial-reasoning or more advanced skills such as language or math. Preferably, a toy should be interesting to a child and provide cognitive stimulation.
There exists a need for improved teethers and toys. In particular, such items may be used while a child is located on the floor, in a bath tub, in a high chair, or in another location where a surface is located nearby. Accordingly, there exists a need for toys and teethers that are configured to removably attach to various surfaces.
SUMMARY
In accordance with embodiments of the present invention, improved toys and teethers are provided. Such suction cup toys may include suction cups disposed on all or a portion of the surface of the toy to removably connect the toy to a nonporous surface. These suction cups may be adapted and arranged such that the force required to remove the toy varies based on which portion of the toy is attached to the surface. The toy may be adapted so that it is easier for a child to grab the toy and remove it from a surface. The toy may be a letter, number, animal, plant, character, geometric shape, organic form, logo, or any other shape that is entertaining and/or educational to a child.
An embodiment of the present invention provides a suction cup toy adapted to removably attach to a nonporous surface and adapted for easy removal from the surface once attached, the suction cup toy comprising:

    
    
        a substantially planar sheet comprising a flexible, chewable material having a front side, a back side opposite the front side, and a perimeter section;
        a first array of suction cups disposed on either of the front side or the back side, wherein each suction cup in the first array extends perpendicularly away from the sheet and is adapted to removably attach to the surface; and
        a means for holding the toy so as to detach the suction cups of the first array from the surface, wherein the means is selected from a group consisting of:
        
            a lip on the perimeter surface of the planar sheet wherein the lip protrudes perpendicular to the sheet and extends a distance away from both the front side and the back side;
            a first textured portion disposed on the back side with a first protrusion extending away from the back side and a second textured portion disposed on the front side opposite the first textured portion with a second protrusion extending away from the front side;
            a passageway extending through the sheet from the back side to the front side, wherein the passageway is adapted to allow a child to grasp and place a lifting force on the toy; and
            a portion of the first array wherein a distance between adjacent ones of the suction cups in the first array is increased so as to allow a child to insert one or more fingers between the adjacent ones of the suction cups.
        
        
    
    


An embodiment of the present invention provides a suction cup toy adapted to removably attach to a nonporous surface and adapted for easy removal from the surface once attached, the toy comprising:

    
    
        a tube comprised of a flexible, chewable material having a surface comprising a front section, a back section opposite the front section, an exterior section, and an interior section opposite the exterior section, wherein the front section and back section are substantially orthogonal to the exterior section and the interior section and the tube is toroidal;
        a first array of suction cups disposed on the back section, wherein each suction cup in the first array extends perpendicularly away from the back section and is adapted to removably attach to the surface;
        a second array of suction cups disposed on the front section, wherein each suction cup in the second array extends perpendicularly away from the front section and is adapted to removably attach to the surface; and
        a third array of suction cups disposed on the exterior section, wherein each suction cup in the third array extends perpendicularly away from the exterior section and is adapted to removably attach to the surface;
        wherein the suction cups in the first array are of substantially equivalent dimensions to the suction cups in the second array and the number of suction cups in the first array is greater than the number of suction cups in the second array, such that the force required to remove the first array from the surface is greater than the force required to remove the second array from the surface.

DETAILED DESCRIPTION
For the purposes of promoting and understanding the principles disclosed herein, reference is now made to the preferred embodiments illustrated in the drawings, and specific language is used to describe the same. It is nevertheless understood that no limitation of the scope of the invention is hereby intended. Such alterations and further modifications in the illustrated devices and such further applications of the principles disclosed and illustrated herein are contemplated as would normally occur to one skilled in the art to which this disclosure relates.
Embodiments of the present invention provide teethers and toys that are chewable and have one or more suction cups disposed on one or more surfaces of the toy. Such items may be referred to as teethers, toys, or suction cup toys herein. Such a toy is capable of sticking to various surfaces, particularly nonporous smooth surfaces, including walls, tables, other toys, and the toy itself. Advantageously, such toys may provide a variety of different textures to increase a child's enjoyment from touching, manipulating, and chewing on the suction cup toy. Chewing on these textured portions applies pressure to the child's teeth or gums, soothing the child and assisting in the growth and development of the child's teeth and gums. The toys may be made in bright colors and interesting shapes to further increase a child's interest and enjoyment. For example, the body of the toy may be a first color while the suction cups may be a second color. The toy may create noise, for example, when a child detaches the suction cups from a surface. Such toys work to improve a child's physical development, particularly with regard to increased fine motor skills. Further, the toys may increase a child's cognitive development by teaching the children cause and effect. So as to ensure a child is able to easily use the toys, they may be adapted so that a child may easily grab and remove the toys from a surface.
FIGS. 1-7
FIGS. 1 through 7 depict a suction cup toy 100 in accordance with an embodiment of the present invention. FIG. 1 depicts a perspective view of the suction cup toy 100. As shown, the suction cup toy 100 may include a flat sheet 102 having a front side 104 and a back side 106. The sheet may be made of a soft, flexible material. In an embodiment, the material is chewable, resilient, and pliable. In an embodiment, the sheet 102 is made of medical grade silicone. Alternatively, the sheet 102 may be made from a flexible plastic, rubber, or any other suitable material. Preferably, the material is nontoxic and free from paints or coatings.
The perimeter 108 of the sheet 102 may be rounded. As will be clear to one of skill in the art, the perimeter 108 may be of any suitable geometric shape, including triangular, rectangular, cylindrical, and polyhedral. In an embodiment, the perimeter 108 may include a raised lip or protrusion that extends away from the sheet 102. The lip may extend away from the front side 104, the back side 106, or both. The lip may serve to make the sheet 102 easier for a child to grasp.
The sheet 102 may be in the form of an object. As shown, the sheet 102 is in the form of a six pointed star/sun, such as a hexagram with rounded points and intersections. As discussed herein, other shapes may also be used. These shapes may cause the toy to be more inviting to a child. Further, the shapes may make the toy educational. For example, toys may be made in basic geometric shapes such as circles, squares, and triangles to assist in teaching a child about shapes. Similarly, toys may be made in the shape of animals, numbers, letters, states, countries, puzzle pieces, or other objects, including as furniture, cars, planes, trains, and so forth. The toys may come in a variety of colors. In this way, the form or appearance of the toy can assist a child in learning basic skills such as language (e.g., the names of the various shapes, objects, and colors), mathematics, problem solving skills, and geometric or spatial relationships.
As shown in FIG. 2, the front side 104 may include one or more suction cups 110. In various embodiments, the suction cups 110 may be arranged in a geometric pattern, an organized pattern, or a random pattern. As shown, the suction cups 110 may be dispersed across a portion of the front side 104. For example, the suction cups 110 may cover only the central portion of the side 104 and may form a radial pattern. Alternatively, the suction cups may be arranged so as to cover the entirety of the side 104 or any desired portion of the side 104. As discussed herein, the suction cups 110 may be arranged in a variety of ways. For example, as shown, adjacent suction cups 110 may be equidistant from one another. Alternatively, the distance between adjacent suction cups 110 may vary according to a pattern or may be random.
Suction cups 110 may also be located on the back side 106 of the suction cup toy 100. The arrangement of suction cups 110 on the back side 106 may be identical to that on the front side 104. Alternatively, a different arrangement of suction cups 110 may be used on the back side 106 than on the front side. For example, the suction cups 110 on the back side 106 may be arranged so as to be offset from the suction cups 110 on the front side 104. Alternatively, the suction cups 110 on the back side 106 may be arranged in a first pattern (such as a random pattern), while the suction cups 110 on the front side 104 are arranged in a second pattern (such as a geometric pattern). Further, suction cups 110 may be disposed on only a single side 104 or 106 of the suction cup toy 100.
The suction cups 110 function to removably attach and detach the suction cup toy to a smooth, nonporous surface. The suction cups 110 are sized and spaced so as to require a predetermined amount of force to remove the suction cups from a surface. For example, the suction cups 110 may support a predetermined weight, such as the weight of the toy. Similarly, different arrangements and/or sizes of suction cups may be used to increase or decrease the force needed to remove the toy from a surface. In an embodiment, a first arrangement and/or size of suction cups is used on the front side 104 of the suction cup toy 100 while a second arrangement and/or size of suction cups is used on the back surface 106 of the suction cup toy 100. In this way, a first force will be needed to remove the suction cup toy 100 from a surface when it is attached using the front side 104 while a second and different force is required to remove the suction cup toy 100 while it is attached to a surface using the back side 106 of the toy. The suction cups may, for example, attach to a table, window, refrigerator, bath tub, wall, mirror, or other flat, nonporous surface. Further, the suction cups may attach to another portion of the device itself or to the surface of another device. For example, the suction cups on a first suction cup toy 100 may attach to the surface or suction cups of a second suction cup toy 100. Alternatively, the suction cups on a suction cup toy 100 may attach to the surface of another toy, including, but not limited to, a building block.
In addition to attaching the suction cup toy 100 to a surface, the suction cups 110 may be used to generate sound. Detaching a suction cup 110 from a surface may generate a noise as the seal between the suction cup 110 and the surface is broken. By changing the arrangement of suction cups 110 on the surface 102, the particular sounds generated by the suction cup toy 100 may be controlled. Further, by pulling the suction cup toy 100 away from the surface with different speeds or from different angles, a child playing with the toy 100 may generate a wide variety of entertaining sounds.
The front side 104 of the sheet 102 further includes one or more holes 112. The holes 112 extend through the sheet 102 from the front surface 104 to the back surface 106. The holes 112 may increase the safety of the suction cup toy 100. For example, the holes 112 decrease the risk that a child could suffocate while using the device by ensuring air can pass through the surface 102. Further, the holes 112 may increase the flexibility of the sheet 102. The holes 112 may be dispersed in a variety of patterns. For example, as shown, the holes 112 may be arranged so as to form a series of concentric circles, with adjacent holes 112 in each circle substantially equidistant from one another. The holes 112 may be located between and adjacent to the suction cups 110. Other arrangements will be clear to one of skill in the art.
In an embodiment, one or more of the holes 112 may be sized so as to accommodate connecting the suction cup toy 100 to another object, such as a high chair, stroller, crib, or other item. For example, a hole 112 may accommodate a strap or ring. Using the hole 112, the suction cup toy 100 may be removably joined to the other object, for example to a high chair, to ensure the suction cup toy 100 does not fall or is not lost while a child is playing with it. For example, a strap affixed to the high chair may pass through the hole 112. The holes 112 may be shaped as a circle, an oval, a square, or any other shape.
In an embodiment, one or more of the holes 112 may be sized so as to enable a child to easily grasp the toy 100 so as to remove the toy 100 from a surface. For example, one or more of the holes 112 may be sized to accommodate one or more of a child's fingers or a child's entire hand. Similarly, one or more of the front surface 104, the back surface 106, and the perimeter 108 may be adapted to enable a child to easily grab the toy 100. For example, the front surface 104 may include an area without suction cups 110 or with a lower density of suction cups 110 to provide an area for a child to grasp the toy 100. The perimeter 108 may include one or more protrusions or areas without suction cups 110 so as to enable the child to easily grab the toy 100. In an embodiment, the perimeter 108 includes a handle. The handle may be sized so as to accommodate a child's hand. In an embodiment, the handle protrudes from the perimeter and is substantially co-planar with the sheet 102. In another embodiment, the handle may protrude from either the front surface 104 or the back surface 106 and be substantially perpendicular to the sheet 102. As will be clear to one of skill in the art, the handle could protrude from any location on the sheet 102 and may form any suitable angle with the sheet.
The front surface 104 may include a design 114 such as a child's face or logo. The design 114 may incorporate at least one of the suction cups 110 and holes 112. For example, as shown the design 114 may use two of the holes 112 to depict the child's eyes and a suction cup 110 to depict the child's nose. Other designs may also be used and will be readily apparent to one of skill in the art. Alternatively, the design 114 may be located on the back surface 106 or on a protrusion from the sheet 102.
In an embodiment, the toy 100 includes a means for holding the toy 100 so as to detach the suction cups 110 from a surface. The means may be selected from a group consisting of: a lip on the perimeter surface of the planar sheet wherein the lip protrudes perpendicular to the sheet and extends a distance away from both the front side and the back side; a first textured portion disposed on the back side with a first protrusion extending away from the back side and a second textured portion disposed on the front side opposite the first textured portion with a second protrusion extending away from the front side; a passageway extending through the sheet from the back side to the front side, wherein the passageway is adapted to allow a child to grasp and place a lifting force on the toy; and a portion of an array of suction cups wherein a distance between adjacent ones of the suction cups in the array is increased so as to allow a child to insert one or more fingers between the adjacent ones of the suction cups. In an embodiment, the toy 100 may include a handle. This handle may be sized so as to accommodate a child's hand.
Portions of the surface 102 may be textured. For example, as shown, each of the points 116, 118, 120, 122, 124, 126 of the hexagram may include a texture. Each of the points 116, 118, 120, 122, 124, 126 may include a different type of texturing. This texturing may serve to provide a child with a variety of fun or soothing surfaces to chew on. For example, different texturing may serve to stimulate a child's gums while a child is teething. Other textures may be interesting for a child to manipulate with his or her fingers. By using a variety of different textures, a child's interest in and enjoyment from the suction cup toy 100 may be increased. Additionally, these textures may enable the child to more easily grab and tug on the toy 100, for example to remove the toy from a surface. With reference to FIGS. 1 through 7, one possible arrangement of texture will now be discussed.
As shown, the north point 116 includes a number of spaced-apart ridges 116a running laterally across the point 116 and extending perpendicular to the surface 102. These ridges 116a may be curved. In an embodiment, the ridges 116a are curved so as to form portions of the circumferences of a series of concentric circles. Further, the ridges 116a further from the center of the surface 102 may be shorter than the ridges 116a closer to the center of the surface 102. Alternatively, as will be clear to one of skill in the art, the ridges 116a may be in another geometric arrangement. For example, the ridges 116a may be straight lines running laterally, longitudinally, or in any other direction across the point 116. In an embodiment, each ridge is shaped as a rectangular prism. Alternatively, the central portion of each ridge may be shaped as a rectangular prism, while the terminal portions of each ridge may slope down to meet the surface 102 at the perimeter 108 of the surface 102.
As shown, the northeast point 118 may include a series of cylinders 118a which extend from the point 118 perpendicular to the surface 102. The cylinders 118a may be arranged in a series of lines running laterally across the point 118, with the number of cylinders 118a in each line decreasing farther from the center of the surface 102. In an embodiment, each cylinder 118a is hollow. Alternatively, each cylinder 118a may be solid. As shown, each cylinder 118a includes a lip running around the circumference of the portion of the cylinder 118a farthest from the surface 102, such that the lip has a greater diameter than the rest of the cylinder. Alternatively, the exterior surface of each cylinder may be of a substantially constant diameter.
In an embodiment, the cylinders 118a near the center of the surface 102 may extend further away from the surface 102 (that is, have a greater height) than the cylinders 118a near the perimeter 108 of the surface 102. Alternatively, the cylinders 118a near the perimeter 108 may extend further from the surface 102 than the cylinders 118a near the center of the surface 102. In an embodiment, the cylinders 118a in each line running laterally across the point 118 extends an equal distance away from the surface 102, with each successive line that is closer to the perimeter 108 extending a successively lesser distance away from the surface 102. Alternatively, each successive line that is closer to the perimeter 108 may extend a successively greater distance away from the surface 102.
As shown, the southeast point 120 includes a ridge 120a protruding perpendicular to the surface 102 around the edge of the point 120. The central portion of the point includes a series of protrusions 120b that may be arranged in a series of lines running laterally across the point 120, with the number of protrusions 120b in each line decreasing farther from the center of the surface 102. Additionally, the lines may be curved such that each line forms a portion of a circumference of one of a plurality of concentric circles. Each protrusion 120b may be a solid cylinder. Alternatively, others shapes may also be used.
As shown, the south point 122 includes a series of ridges 122a protruding perpendicular to the surface 102. The ridges 122a may run substantially longitudinally along the point 122. Each ridge 122a may be in the form of a horizontal cylindrical segment with half-hemispherical ends.
As shown, the southwest point 124 includes a series of projections 124a protruding perpendicular to the surface 102. Each projection 124a may be a hemisphere. The projections 124a may be arranged in lines running laterally across the point 124. The projections 124a may be of varying sizes. For example, the projections 124a closest to the perimeter 108 of the surface 102 may be larger than those farther from the perimeter 108 of the surface 102.
As shown, the northwest point 126 may include a series of ridges 126a protruding perpendicular to the surface 102. The series of ridges 126a may extend laterally across the point 126. Further, the ridges 126a may be rounded and of varying sizes. When viewed cross-sectionally, the ridges 126a may be shaped as overlapping parabolic curves, with the curves closer to the perimeter 108 of the point 126 smaller than those farther from the perimeter 108 of the point 126.
FIGS. 8-14
FIGS. 8 through 14 depict a suction cup toy 800 in accordance with a second embodiment of the present invention. As shown, the suction cup toy 800 may comprise a sheet 802 in the shape of an insect, such as a bee. As shown, the front surface 104 may include a design 114 such as a child's face or a logo. The design 114 may incorporate at least one of the suction cups 110 and holes 112. For example, as shown the design 114 may use two of the holes 112 to depict the child's eyes and a suction cup 110 to depict the child's nose. Other designs may also be used and will be readily apparent to one of skill in the art. Suction cups 110 may be arranged across both a front side 104 and a back side 106 of the sheet 802. The sheet 802 may include one or more textured portions 808. These textured portions may form the insect's wings 810, stinger 812, head 814, or other portions of the insect's body. For example, a series of curved ridges 816 may form the details on each of the wings 810. One or more protrusions 818 may form the texture on the stinger 812. A series of ridges 820 may form the texture on the head 814. Other textures or arrangements of textures may also be used.
FIGS. 15-21
FIGS. 15 through 21 depict a suction cup toy 1500 in accordance with a third embodiment of the present invention.

FIGS. 57-62
FIGS. 57 through 62 depict arrangements of suction cups 110 on planes of different shapes. For example, various arrangements may be preferred based on the size and shape of the sheet to be covered. Depicted are exemplary arrangements based on several possible shapes. As will be clear to one of skill in the art, other possible arrangements of suction cups 110 may also be desirable depending on, for example, the size and shape of the sheet, the size of the suction cups, the density of suction cups needed to support the weight of the toy or exert a desired force upon a surface, and the presence of holes, designs, textured areas, or other features on the surface of the toy. For example, by increasing the density of suction cups 110 on a sheet or the size of the suction cups 110, a greater force will be exerted between the sheet 102 and another surface when the suction cups 110 are attached to the other surface.
As shown in FIG. 57, a square array of suction cups 110, with each suction cup 110 located equidistant from the adjacent suction cups in the same row or column, may be used to optimally cover a square sheet 5702. An equal number of suction cups may be placed in each row and column.
As shown in FIG. 58, a triangular array of suction cups 110 may be used to optimally cover a triangular sheet 5802. The distance between each row of suction cups 110 may be equivalent to the distance between adjacent suction cups 110 in each row.
As shown in FIG. 59, suction cups 110 may be arranged in a series of concentric rings to optimally cover a circular surface 5902. A single suction cup 110 may be placed at the center of the sheet 3102. As shown, adjacent suction cups 110 in each ring may be equidistant from one another. Similarly, suction cups that are radially adjacent may be equidistant from one another.
As shown in FIG. 60, a rectangular array of suction cups 110, with each suction cup 110 located equidistant from the adjacent suction cups in the same row or column, may be used to optimally cover a rectangular sheet 6002. An equal number of suction cups may be placed in each row. Similarly, each column may contain the same number of suction cups. The number of rows and columns used may depend on the size of the sheet 3202 so as to obtain the desired coverage of the sheet.
As shown in FIG. 61, suction cups 110 may be arranged in a series of concentric ellipses to optimally cover an elliptical sheet 6102. A single suction cup 110 may be placed at the center of the sheet 6102. As shown, adjacent suction cups 110 in each ring may be equidistant from one another. Similarly, suction cups that are radially adjacent may be equidistant from one another.
As shown in FIG. 62, suction cups 110 may be arranged in two triangular arrays to optimally cover a rhomboid sheet 6202. The distance between each row of suction cups 110 may be equivalent to the distance between adjacent suction cups 110 in each row.
FIGS. 63-65
With reference to FIGS. 63 through 65, in an embodiment, each suction cup 110 may contain a head 6304 located on a body 6306. In an embodiment, each head 6304 is circular when viewed perpendicularly while each body 6306 is cylindrical and protrudes perpendicular to the sheet 6302. The interior face 6308 of each head 6304 may be curved. The suction cups 110 may be made from an elastic material. As a suction cup 110 is pressed against a surface 6310, the volume of space 6312 between the interior surface 6308 of the head 6304 and the surface 6310 decreases as the head 6304 deforms. Fluid, such as air or water, is expelled from this volume 6312. Once the suction cup 110 is no longer pressed against the surface 6310, the elastic material of the suction cup 110 attempts to regain its original shape. Due to the lower pressure in the volume 6312, the suction cup 110 adheres to the surface.
The force exerted by each suction cup depends on the size of the suction cup, or more specifically, on the area of the suction cup. By increasing the suction cup's size, great force can be exerted on a surface. Additionally, the force depends on the difference between the pressure inside the cup and the pressure outside the cup. By decreasing the amount of air that is able to leak in to the suction cup during use, greater force will be exerted on the surface.
Alternatively, in an embodiment, each suction cup 110 may comprise a head 6304 attached directly to the sheet 6302. In other words, the body 6306 may be omitted. This may decrease the likelihood that a suction cup 110 will become separated from or break off of the sheet.
In order to exert the greatest possible force against a surface 6310, it is necessary to optimally cover the sheet 102 with suction cups. One optimal configuration is to put as little distance between suction cups 110 as possible. If the heads 6304 of adjacent suction cups 110 touch or press against one another, one or both of the suction cups 110 may be unable to properly seal against a surface 6310. Accordingly, for suction cups that do not deform laterally, the spacing between adjacent bases 6306 must be equal to just over twice the difference in the radius of the base 6306 and the radius of the head 6304 if the suction cups 110 are identically-sized. Alternatively, if the heads 6304 are directly attached to the sheet 6302, the distance between the portion of adjacent heads 6304 that attaches to the sheet 6302 must be equal to just over twice the different between the radius of the head 6304 at the head's widest point and the radius of the head 6304 at the point where the head attaches to the sheet 6302. For suction cups that deform laterally when pressed against a surface, the space between adjacent bases should be increased by twice the difference between the radius of a deformed suction cup and the radius of the suction cup at rest.
FIG. 66
FIG. 66 depicts another embodiment of the present invention. As shown, a suction cup toy 6600 may include a sheet 6602 with a front side 6604 and a back side 6606. The front side may include a textured pattern. For example, the front side 6604 may include a series of protrusions 6608 arranged in a grid pattern. Each protrusion 6608 may include a cylinder with a beveled edge, such that the diameter of the cylinder decreases further from the sheet 6602. In an embodiment, this textured pattern covers the entire face of the front side 6604, such that partial protrusions 6608a (not shown) are arranged along the perimeter of the front side 6604.
A design may be located on the front surface 6604. The design may incorporate the protrusions 6608 of the textured pattern into the design. The texture may serve to visually or mechanically stimulate a child. For example, the design may be visually interesting such that a child is motivated to look at or handle the suction cup toy 6600. Similarly, the texture may be physically or mechanically stimulating such that a child is motivated to touch or chew on the suction cup toy 6600.
In contrast, the back side 6606 may contain one or more suction cups 110. As discussed herein, the suction cups 110 may be arranged in any suitable pattern.
FIG. 67
As shown in FIG. 67, a suction cup toy 6700 in accordance with an embodiment of the present invention may be used as a construction toy. The suction cup toy 6700 may be attached to one or more blocks 6702, 6704, 6706 using suction cups 110 so as to act as a mortar holding the blocks 6702, 6704, 6706 together. In this way, complex structures may be built by combining a number of suction cup toys 6700 and blocks 6702, 6704, 6706.
Similarly, a suction cup toy 6700 may be used to affix other objects together. For example, one side of a suction cup toy could be attached to a plate while a second side of the toy simultaneously is attached to the tray on a high chair. In this way, the suction cup toy restrains the plate from moving such that the plate will remain adjacent to the high chair while a child is eating.
It is understood that the preceding is merely a detailed description of some examples and embodiments of the present invention and that numerous changes to the disclosed embodiments can be made in accordance with the disclosure made herein without departing from the spirit or scope of the invention. The preceding description, therefore, is not meant to limit the scope of the invention but to provide sufficient disclosure to one of ordinary skill in the art to practice the invention without undue burden.
