CHILD ACTIVITY APPARATUS, SYSTEM, AND METHOD

FIELD OF THE INVENTION

The present invention pertains generally to systems for standing, walking training and imaginative play for infants, new toddlers, and toddlers. More specifically, the invention relates generally to systems for young children's exercise and entertainment while also providing opportunities for standing and walking training.

BACKGROUND
Description of the Related Art

Frequently, children learn to walk by “furniture surfing” (e.g., infants who are just starting to stand, holding onto sofas and coffee tables as they navigate their way around a living room). At least in part, this may be due to the lack of an alternative method. Obviously, “furniture surfing” represents a risk to the child, e.g., in the event the child should fall against a sharp corner or edge.

A primary alternative to “furniture surfing” is “parent surfing”, which involves the active participation of the adult in holding the child's hands while the child attempts to walk. This method is often short—lived due to adult fatigue.

Today, there are few readily available alternatives which provide the functional combination of walking training, exercise and entertainment. Generally, the currently readily available alternatives fail to provide at least one of the desired functions and often have significant safety limitations, even with parental supervision.

Heretofore, other solutions have tended to be heavy, expensive, complicated, difficult to set up, difficult to manufacture, and costly to manufacture. Additionally, safety-related features have been limited.

Therefore, a need exists for a system which is safe, inexpensive and easily manufactured, and which provides child walking training in combination with other functions.

SUMMARY

From the foregoing discussion, it should be apparent that a need exists for an apparatus, system, and method that provide a safe and effective method for child walking training. Beneficially, such an apparatus, system, and method would include features and accessories that would hold a child's interest as it plays and as it grows older, including after when it learns to walk. Accordingly, the present invention has been developed to provide an apparatus, system, and method for child walking training that overcome many or all of the above-discussed shortcomings in the art.

The system, in one embodiment, includes an upper graspable bar composed of bars and bar connectors connected to substantially circumscribe an upper area. The system also includes a lower base having extremities that engage the floor when the child activity system is resting on the lower base. The lower base is configured to maintain the combined center of gravity of the child activity system and a child within the extremities of the lower base. The system also includes a plurality of attacher bars connecting the upper graspable bar and the lower base. The attacher bars also support the upper graspable bar and the lower base substantially rigid with respect to each other. The system is selectively configurable by hand without tools between a plurality of configurations. These configurations include a walking training configuration, a play feature configuration, and a storage configuration. In the storage configuration the child activity system is at least partially disassembled to take up less space.

According to one embodiment, the basketball hoop includes a u-shaped coupler which is configured to rest on a horizontally oriented bar of one of the upper graspable bar and the lower base.

According to one embodiment, the tent material comprises one or more fasteners to secure the tent material to the child activity system to form a tent-like structure. The tent material is drapable over the upper graspable bar with the fasteners attached to the lower base. The tent-like structure has one or more walls that extend to the ground when the child activity system is resting on the lower base.

According to one embodiment, the bar connectors are concurrently friction-fittable to at least two bars. According to one embodiment, the bar connectors comprise one or more three-way elbow bar connectors. According to one embodiment, the bars and bar connectors of the upper graspable bar form a rectangle comprising two ends and two sides. The sides are greater in length than the ends and the ends are disposed at ends of the system. The system is selectively rest-able on the lower base and the ends.

According to one embodiment, the play feature configuration comprises orienting the child activity system to rest on an end. According to one embodiment, one of the bars of the activity system comprises two or more bars and one or more straight bar connectors. According to one embodiment, the system includes one or more bar extenders.

According to one embodiment, the walking training configuration comprises resting the child activity system on the lower base. According to one embodiment, the walking training configuration includes a toy mounted on the upper graspable bar. The child may be placed opposite of the toy to motivate the child to walk toward the toy.

According to one embodiment, the graspable bar and the lower base each have a length and a width and the length of the upper graspable bar is substantially the same as the length of the base.

Initially referring to FIG. 1, one embodiment of a child activity system 200 is shown. As shown, the child activity system 100 includes a number of bars and bar connectors configured to provide a stable and safe system on which children can play while learning to walk. The child activity system 100 includes an upper graspable bar 103 formed by two upper sidebars 104, two upper end bars 106, and four three-way bar connectors 108. It also includes a lower base 109 formed by four lower end bars 114, six elbow bar connectors 116, and two lower side bars 118. Attacher bars 110, connect the upper graspable bar 103 to the lower base 109.

According to one embodiment, the bars and bar connectors of the child activity system 100 is constructed of light-weight, strong, and stable material. According to one embodiment, the child activity system 100 is constructed of plastic pipes, e.g., ABS (Acrylonitrile Butadiene Styrene), or other child-safe plastic. According to one embodiment, the strength of child activity system 100 is provided, at least in part, by advanced materials of plastic pipes and couplings that are extruded or molded from ABS or other child-safe plastic. As an example, pipe diameters could be in the range of ½″ to 1″ or more, if appropriate, and formed in a way comparable to Schedule 40 PVC. Although the pipes and couplings may be formed in a similar form, shape or function to PVC piping, other materials may be used in some embodiments. For example, ABS, material formed from a corn or vegetable polymer, or other child safe materials may be used to form the piping of the child activity system 100.

According to one embodiment, the diameter chosen will yield a bar circumference that is able to be grasped by the hand of a small child. Upon reading the teachings of this specification one of ordinary skill in the art will understand that, the type of plastic used and the pipe diameters can vary greatly. For example, under appropriate circumstances, considering issues such as cost, material availability, weight, durability, child safety, market demand, etc., other materials or diameters may be used. Additionally, the type of material used by different bars and/or connectors may also vary within a single child activity system 100.

According to one embodiment, the size of the child activity system 100 is configured to fit about 80 to about 90 percent of children approximately ten to eighteen months of age. For example, the height, width, bar circumference may be designed for this an age group. Such an embodiment, for example, may be directed at infants that are learning to walk. Other sized embodiments, such as larger embodiments of the present invention may be suited to the training of physically challenged individuals and in patient physical therapy.

According to one embodiment, the child activity system 100 is configured to allow an adult to assemble or disassemble the child activity system 100 without the use of tools. This may be accomplished by having one or more connectors which are friction-fittable to one or more bars.

The geometry and shape of the child activity system 100 can be very important to the safety and enjoyment it provides for children. According to one embodiment, the child activity system 100 is configured to allow a child to move in all directions around, under and through the child activity system 100 essentially without limitation due to the lack of walls between the various bars. This may help to promote interest and continuous usage by the child for more than a few brief moments.

The upper graspable bar 103 of FIG. 1 is shown enclosing a rectangular area. According to other embodiments, the upper graspable bar 103 may enclose or substantially enclose areas of other polygonal or non-polygonal shapes. According to one embodiment, the shape of the upper graspable bar 103 and the enclosed or substantially enclosed area is such that a child is bounded on substantially opposite sides. For example, an infant 102 standing within the enclosed area is bounded on its right side by an upper side bar 104 and on its left side by an upper side bar 104 (not visible in FIG. 1). The infant 102 bounded on opposite sides may then be less prone to injury due to having one or more bars to grasp regardless of the direction it is facing. Additionally, the infant 102 bounded on opposite sides may also be less prone to injury due to its fall being stopped or softened by the upper graspable bar 103.

The geometric relationship of the upper polygonal peripheral graspable bar 103 and the lower base 109 provide stability for the child activity system 100. According to the depicted embodiment, the lower base 109 substantially forms a rectangular shape and substantially encloses a rectangular area with the full lower base 109 resting on the ground. The contact of the lower base 109 with the ground at points not directly below the upper graspable bar 103 or the area enclosed by the upper graspable bar 103 helps to maintain the center of gravity of the child activity system 100 within the extremities of the lower base 109. This may help to keep the child activity system from tipping.

According to one embodiment, the lower base 109 makes contact with the ground at a sufficient distance from the area directly below the upper graspable bar 103 that both the center of gravity of the infant 102 and the child activity system 100 are maintained within the extremities of the lower base 109. For example, according to the depicted embodiment, the total area enclosed by the lower base 109 is sufficiently greater than the area enclosed by the upper graspable bar 103 to maintain the combined center of gravity of the child activity system 100 and the infant 102 within the area enclosed by the lower base 109, even when a child leans on or applies a force to the infant activity system.

According to one embodiment of the present invention, when an infant 102 applies forces to the upper graspable bar 103 the child activity system 100 will not tilt or tip over. This provides a safe and stable environment for children to play in. According to one embodiment, as shown in FIG. 1, the width of the lower base 109 is approximately three times the width of the upper graspable bar 103 (or greater) while maintaining approximately the same length. In other words, the ratio of the width of the lower base 109 to the width of the upper graspable bar 103 is approximately three, in one embodiment. According to other embodiments, the lengths and/or widths may have different ratios.

The lengths and configurations of the various bars, as well as the dimensions of the child activity system 100, can vary significantly. The illustrated lengths are exemplary only. Also, the various bars, according to some embodiments, may be composed of one or more bars and one or more connectors.

Although the lower base 109 substantially forms a rectangular shape substantially enclosing a rectangular area, the shape and configuration of the lower base 109 can vary considerably. For example, the base may enclose an area but need not even substantially enclose an area. According to one embodiment, the lower base 109 forms a full rectangular shape and encloses an area. According to another embodiment, the base comprises a number of bars that extend outward from the attacher bars 110. The outward extending bars could serve to provide stability to the upper graspable bar.

According to the embodiment of FIG. 1, as shown, an infant 102 may walk or stand within the area enclosed or substantially enclosed by the upper graspable bar 103 of the infant activity system 100. The enclosed or substantially enclosed area may provide a safe environment for the infant 102 to learn to stand and/or walk. Alternatively or additionally, according to the depicted embodiment, the infant 102 may walk or stand on the outside of the upper graspable bar 103. Due to the stability of the child activity system 100, the infant 102 may use the upper graspable bar 103 to at least partially support its weight. Additionally, the infant 102 may grasp or use an attacher bar 110, the upper end bar 106, or the upper side bar 104 to pull itself up to a standing position.

Further description, explanation, and possible variations of the embodiment of FIG. 1 are provided in relation to the following figures.

FIG. 2A depicts a top view of the child activity system 100 of FIG. 1.

FIG. 2B depicts a side view of the child activity system 100 of FIG. 1.

FIG. 2C depicts end views of the child activity system 100 of FIG. 1 with the upper graspable bar 103 at three separate heights h1, h2, and h3. According to the depicted embodiment, the attacher bars 110 comprise a small diameter bar 140 and a large diameter bar 150. According to the depicted embodiment, the large diameter bar 150 is the same diameter as other bars, such as lower side bar 118, lower end bar 114, and upper end bar 106. The small diameter bar 140 fits within the larger diameter bar 150 and is allowed to slide between heights h1, h2, and h3. According to one embodiment, the small diameter bar 140 is fixed at some location within the large diameter bar 150 by a clip or other fastener.

In the depiction of FIG. 2C, when the upper graspable bar is at height h3, the upper graspable bar 103 rests on the large diameter bar 150 at point 201. This may be the case, for example, if the large diameter bar 150 and the small diameter bar 140 are of approximately equal length, or the small diameter bar 140 is of shorter length than the large diameter bar 150. According to other embodiments, the small diameter bar 140 is of greater length than the large diameter bar. This may keep the upper graspable bar 103 from resting on the large diameter bar 150 at point 201 and thereby limit the chance of a pinching hazard between the upper graspable bar 103 and the large diameter bar 150 at point 201.

According to the depicted embodiment of FIGS. 1 and 2A-2C, the small diameter bar 140 extends upward from within the large diameter bar 150 to the upper graspable bar 103 and the large diameter bar 150 connects to the lower base 109. According to another embodiment, the position of the small diameter bar 140 and the large diameter bar 150 is switched. This may be advantageous in some embodiments, of allowing for easier adjustment of the height (h1, h2, h3) of the upper graspable bar. See FIG. 4B for further explanation.

According to one embodiment, the child activity system 100 may be at least partially disassembled. According to one embodiment, the child activity system 100 is at least partially disassembleable by detaching one or more bars from one or more bar connectors. According to one embodiment, some bars at certain points are removably attached to one or more bar connectors while the same or different bars are permanently attached. According to one embodiment, removable attachments include a friction fit between a bar and a connector. According to another embodiment, removable attachments include one or more holes and one or more fasteners. Other embodiments of removable attachments include both a friction fit and the use of a fastener. According to one embodiment, permanent attachments include a bar glued to a bar connector. Other methods of permanently attaching a bar to a bar connector will be apparent to one skilled in the art in light of the present description.

Turning now to FIGS. 3A-3D, exemplary detachability of child activity system 100 is shown. FIGS. 3A-3B depict the detachability of the child activity system 100 according to one embodiment. FIG. 3A, the child activity system 100 is shown as detachable can be characterized as comprising two end support segments 300 that are interchangeable, along with two upper side bars 104 and two lower side bars 118. According to the depicted embodiment, the connection between the upper side bars 104 and the lower side bars 118 with the bar connectors 108, 116 of the two end support segments 300 is a detachable connection. According to one embodiment, the upper and lower side bars 104, 118 are modular interchangeable components. For example, according to one embodiment, a upper side bar 104 could be connected in place of a lower side bar 118, and vice versa.

FIG. 3B shows the components of an end support segment 300. Each end support segment 300 includes upper 310 and lower 320 end segments that receive one another telescopically as described in further detail in relation to FIGS. 4B and 4C. In one embodiment, upper 310 and lower 320 segments are comprised of components that are permanently attached to provide ease of assembly, disassembly and shipment. For example, the upper segment 310 includes two small diameter bars 140 and upper end bar 106 permanently bonded to two three way bar connectors 108. The lower segment 320 includes two portions, each of which include a large diameter bar 150 and a lower end bar 114 permanently bonded to two elbow bar connectors 116.

The permanent bonds between particular components may make the child activity system 100 easier to assemble while still allowing it to be dissembled for transportation and/or storage.

Turning to the next figures, FIGS. 3C-3D depict the detachability of the child activity system 100 according to another embodiment. As shown, the child activity system 100 comprises two vertical end supports 350 that are interchangeable and usable on either side. The vertical end supports 350 comprise an upper end segment 310 with two lower support tubes 150 telescopically received; the lower support tubes 150 each having an elbow bar connector 116 permanently bonded thereto. Also included in this embodiment are two horizontal base supports 351 that are useable on either side of the child activity system 100. Each horizontal base support 351 comprises a lower side bar 118 having two lower end bars 114 connected at each ends with elbow bar connectors 116 permanently bonded. Lastly included are two interchangeable upper side bars 104.

The permanent bonds between particular components may make the child activity system 100 easier to assemble while still allowing it to be dissembled into a smaller size for transportation and/or storage.

Turning to FIGS. 4A-4D, 5A-5B, and 6A-6b exemplary connection mechanisms using spring fasteners are shown. In FIG. 4A one exemplary embodiment of an upper sidebar/lower sidebar (sidebar) 104/118 is shown. The sidebar 104/118 is shown with a spring fastener 111 extending through a hole in the sidebar 104/118. The spring fastener 111 is depressible for insertion into a bar connector, for example bar connectors of FIGS. 5A-6B.

FIG. 4B depicts one exemplary embodiment of the components of an attacher bar 110. According to the depicted embodiment, the attacher bar 110 includes a large diameter bar 150 and a small diameter bar 140. Although the small diameter bar 140 and the large diameter bar 150 are shown separated, the small diameter bar 140 fits telescopically within the large diameter bar 150. The small diameter bar 140 has a spring fastener 141 extending through a hole. The large diameter bar 150 has a plurality of holes 151 for selectively receiving the spring fastener 141. Similar to the spring fastener 11 of FIG. 4A, the spring fastener 141 is depressible for insertion and/or adjustment of the small diameter bar 140 in the large diameter bar 150. For example, the spring fastener 141 of the small diameter bar 140 can be depressed and inserted/adjusted between one of the holes 151. Thus, the length of the attacher bar 110 can be varied and provide a variety of heights for the graspable bar 103, such as heights h1, h2, h3 of FIG. 3C.

According to one embodiment, the large diameter bar 150 includes flexible sleeve that covers the holes 151. The flexible sleeve allows the spring fastener 114 to protrude through the hole, but limits entry into the holes 151 from outside the bar. For example, the flexible sleeve may limit a child's fingers from getting caught in one of the holes 151. A child's finger in one of the holes 151 when the small diameter bar 140 may be dangerous and could result in injury to the finger. The flexible sleeve limits this danger. According to one embodiment, the flexible sleeve is formed of shrink fit rubber tubing that is placed over the large diameter bar 150 at the location of one or more holes 151.

According to one embodiment, the large diameter bar 150 is connected to the lower base 109 and according to other embodiments is connected to the upper graspable bar 103. According to one embodiment, it is desirable to have the large diameter bar 150 connected to the upper graspable bar 103 and the small diameter bar 140 connected to the lower base 109 because it may make it easier to adjust the height. For example, according to this embodiment, because the spring fastener 141 extends through one of the holes 151 of the large diameter bar 150, it may be possible to simply grasp the large diameter bar 150, press the spring fastener 141 and lift in order to increase the height. This is because gravity will pull on the lower base 109 and the small diameter bar 140 downward. This may require only the use of one hand to adjust the length of a single attacher bar 110. According to one embodiment, if the small diameter bar 140 is connected to the upper graspable bar 103 one hand is needed to press the spring fastener 141 another hand is needed to push-pull on the small diameter bar 140 or the upper graspable bar. This may require the use of two hands to adjust the length of a single attacher bar 110.

FIGS. 4C and 4D depict exemplary spring fasteners 111, 141 for use within bars to provide a removable and/or adjustable connection. FIG. 4C shows one embodiment of a Y-spring fastener 111/141 for use within a bar, such as a side bar 104/118, a small diameter bar 140 or any other bar of the activity system 100. The Y-spring fastener 111/114 has a button 401 for extending through holes in bars and/or bar connectors. The Y-spring fastener 111/141 is compressible along the arrows 402. The Y-spring fastener 111/141 may be inserted into a bar with the button 401 extending through a hole and the opposite arm of the “Y” pressing on the opposing wall within the bar. Because the Y-spring fastener 111/141 is compressible, the button 401 may be pressed to insert/adjust the bar into another bar or connector. For example, if the Y-spring fastener 111/141 resides within a siderbar 104/118, then the button 401 may be pressed to insert the sidebar 104/118 into a connector. If the Y-spring fastener 111/141 resides within the small diameter bar 141 the button 401 may be pressed to insert or adjust the small diameter bar 140 in the large diameter bar 150.

Due to the geometry of the Y-spring fastener 111/141 it may be useful in bars where the holes are very near the end of the bars. This is because the Y-spring fastener 111/141 does not extend very far past the button 401 in at least one direction. Thus, the Y-spring fastener may be useful in bars that are connected to bar connectors.

FIG. 4D shows one embodiment of a C-spring fastener 111/141 for use within a bar, such as a side bar 104/118, a small diameter bar 140 or any other bar of the activity system 100. The C-spring fastener 111/114 has a button 401 for extending through holes in bars and/or bar connectors. The C-spring fastener 111/141 is compressible along the arrow 403. The C-spring fastener 111/141 may be inserted into a bar with the button 401 extending through a hole and the legs 405 pressing on the opposing wall within the bar. Because the C-spring fastener 111/141 is compressible, the button 401 may be pressed to insert/adjust the bar into another bar or connector. For example, if the C-spring fastener 111/141 resides within a siderbar 104/118, then the button 401 may be pressed to insert the sidebar 104/118 into a connector. If the C-spring fastener 111/141 resides within the small diameter bar 141 the button 401 may be pressed to insert or adjust the small diameter bar 140 in the large diameter bar 150.

Due to the geometry of the C-spring fastener 111/141 it may be useful in bars having smaller diameters. This is because the distance which the button 401 may be pressed is not limited by any other portion of the spring fastener. For example, the Y-spring fastener 11/141 of FIG. 4C is limited in how far it can compress within a pipe due to the opposing “arms” of the Y. Thus, the C-spring fastener may be useful in bars having smaller diameters, such as the small diameter bar 140 of an attacher bar 110.

In light of the present disclosure one of skill in the art will recognize that the spring fasteners 111/141 of FIGS. 4C and 4D are exemplary only and that significant variation is possible without departing from the scope and content of the present invention. For example, the size and length of the buttons 401 may vary to accommodate different size holes or different thicknesses in the walls of the bars. Also, other considerations may call for variations in button sizes. For example, a longer button 401 may limit the slippage of an engaged bar or bar connector, allowing for a stronger hold. On the other hand, a shorter button 401 may be easier to press and provide for easier adjustment.

Additionally, the material of which the spring fasteners 111/141 is made may vary considerably. According to one embodiment, they are formed of nylon. According to other embodiments, they may be formed of a plastic, metal, rubber, or other material. According to one embodiment, the separate portions of the spring fasteners 111/141 are made of different materials.

Turning now to FIGS. 5A, 5B, 6A, and 6B exemplary bar connectors 116, 108 are shown. FIGS. 5A and 5B depict one exemplary embodiment of an elbow bar connector 116 having one or more holes 510. The holes 510 may each receive the button of a spring fastener, such as spring fasteners 111/141 of FIGS. 4A-4D. The depicted bar connector 116 is at least partially hollow, similar to an elbow for connecting pipes. According to one embodiment, the internal diameter of the bar connector 116 is approximately the same as the external diameter of a bar. Thus, a bar may be inserted and received by the elbow bar connector 116 and may be held in place, at least in part, by the button of a spring fastener. The elbow bar connector 116 has two openings for receiving bars. The elbow bar connector 116 may connect to two bars simultaneously and maintain the two bars at a substantially 90 degree angle. Other embodiments may include elbow bar connectors 116 having other angles.

For example, according to one embodiment, the lower side bar 118 of FIG. 4A is to be connected to the elbow bar connector 116 of FIGS. 5A and 5B. A user may take the lower side bar 118 in one hand and the elbow bar connector 116 in another hand. The user can connect the two by pressing the button 401 of the spring fastener 111 and inserting the lower side bar 1118 into the opening of the elbow bar connector 116. The user can adjust the position of the lower side bar 1118 within the elbow bar connector 116 until the button 401 of the spring fastener 111 extends through the hole 510. The lower side bar 118 is then substantially secured within the elbow bar connector 116.

According to one embodiment, bars are dry-fitted into the elbow bar connector 108. According to one embodiment, this dry-fit system allows the infant activity system 100 to be assembled by hand, without the use of tools, adhesives or fasteners, which greatly simplifies the assembly/disassembly process for the user. According to one embodiment, the fit between the bars and the bar connectors is similar to the connection between polymerized vinyl chloride (PVC) pipes and PVC pipe connectors. The close tolerances of industry-standard PVC pipes may allow the infant activity system 100 to be very stable.

FIGS. 6A and 6B depict one embodiment of a three way bar connector 108. The three way bar connector 108 has three openings for receiving bars. The three way bar connector 108 may connect to three bars simultaneously and maintain the three bars at a substantially 90 degree angle from each other. Other embodiments may include three way bar connectors 116 having other angles. The three way bar connector 108, according to the depicted embodiment, has a plurality of holes 610 on each opening. This may allow bar connectors to be attached to each end of a bar in a variety of orientations. Other embodiments, may include fewer holes 610, no holes 610, or holes 610 only on certain openings. The three way bar connector 108 may be attached to one or more bars similar to the manner described above in relation to the elbow bar connector 116 of FIGS. 5A and 5B.

Significant variation is possible on the above discussed bar connectors 116, 108. For example, the openings, holes, material, and other aspects of the bar connectors may vary between embodiments. According to one embodiment, all of the openings are the same size on a single bar connector. According to other embodiments, the openings may be of different sizes on the same bar connector. According to varying embodiments, a bar is received into the bar connectors 116, 108 to different depths. For example, the openings may extend further from the body, providing additional support and strength in holding an inserted bar in a desired position. Also, the thickness of the walls of the bar connectors 116, 108 and the pipes may vary according to need for strength, weight, etc.

FIG. 7 depicts one embodiment for connecting bars of different sizes to the same bar connector. The depicted embodiment is the upper end segment 310 of the end support segment 300 of FIG. 3A. The bar connectors 116 connect bars of different sizes. Specifically, the bar connectors 116 connect an upper end bar 106 to two small diameter bars 140.

According to the depicted embodiment, the openings of the three way bar connectors 116 are all the same size and are suitable to fit the diameter of the upper end bar 106. Because the small diameter bars 140 have a smaller diameter than the upper end bar 106, spacer 710 is combined to the small diameter bar 140 and to the three way bar connector 116. Thus, the smaller diameter bar 140 is received into the larger opening of the three way bar connector 116.

According to one embodiment, the spacer 710 may be permanently bonded on the small diameter bar 140 and/or in the three way bar connector 116. Other embodiments may be dry fitted for easy assembly and disassembly.

FIGS. 8A through 8D illustrate one embodiment of the child activity system 100 dissembled and placed in a mode for storage and/or transportation. FIG. 8A shows a perspective view of the child activity system 100 in a storage/transportation mode.

According to one embodiment, the child activity system 100 is disassembleable according to the depiction of FIGS. 3A and 3B. The end support segments 300 are arranged to directly oppose one another while upper 104 and lower 118 side bars have room to be placed between. The resulting storage/transportation arrangement is dense and compact. This can lead to significant convenience for users due to small storage area and ease of assembly/disassembly. Additionally, reduction in size for shipping may significantly help reduce the shipping price and lead to economy and profitability of the child activity system 100.

FIG. 8B shows a top view of the child activity system 100 in a storage/transportation mode. FIG. 8C shows a side view of the child activity system 100 in a storage/transportation mode. FIG. 8D shows an end view of the child activity system 100 in a storage/transportation mode.

Turning now to FIG. 9 an exemplary child activity kit 900 is shown. According to one embodiment, the child activity kit contains primary components used to assemble the infant activity system according to the embodiment of FIG. 1. According to one embodiment, the infant activity system 100 is provided in the form of the child activity kit 900 which can then be at least partially assembled for use and/or sale. The child activity kit 900 includes a variety of bars and bar connectors. Additional, fewer, or alternate items may be included in various embodiments. For example, some embodiments may include some of the accessories, toys, and/or play features depicted in FIGS. 11 through 18.

According to the depicted embodiment, the child activity kit 900 includes four side bars 104/118 of approximately equal length, four attacher bars 110 of approximately equal length, and six end bars 106/114. According to one embodiment, each of the side bars 104/118 are interchangeable with each other, each of the four attacher bars 110 are interchangeable with each other, and each of the end bars 106/114 are interchangeable with each other. According to other embodiments, the bars of the same type (i.e. the side bars 104/118) are not interchangeable. For example, there may be upper side bars 104 which are different from the lower side bars 118. The child activity kit 900 includes four three way bar connectors 108 and eight elbow bar connectors 116. As will be clear to one of skill in the art upon reading this description, the four attacher bars 110 are exemplary only and could be replaced with the telescoping attacher bars 110 of FIG. 4B.

According to the depicted embodiment, the child activity kit 900 also includes a flexible bag container 902 and an assembly instruction sheet 904. According to one embodiment, both the flexible bag container 902 and the assembly instruction sheet 904 include the product name or other product indicia 906. According to one embodiment, the flexible bag container 902 is reusable and may allow the disassembled child activity system 100 to be stored therein.

The bars depicted are exemplary only and may be interchanged with other bars of different configurations. For example, according to one embodiment, the side bars 104/118 are each composed of two bars of about half length and a straight bar connector. The straight bar connector may be a bar connector that connects to two bars and maintains them approximately along the same axis. According to such an embodiment, there may be advantages to composing longer bars, such as the sidebars 104/118, of multiple smaller bars and one or more connectors. For example, side bars 104/118 formed of two bars and a straight connector are, in some embodiments, stronger. One embodiment includes a plurality of bars of equal length and multiple straight connectors which can then be connected to form the respective side bars 104/118, end bars 16/114, and attacher bars 110.

According to one embodiment, the components of the child activity kit 900 are different colors. For example, the components could be color coded. This, in conjunction with a color assembly instruction sheet 904 may help to improve the ease with which child activity kit 900 is assembled to form the child activity system 100. Additionally, the forming of the components different colors may make the child activity kit 900 or system 100 more marketable and may help to encourage interest in and use of the child activity system 100 by children. For example, according to one embodiment, the side bars 104/118 are a single color, the attacher bars 110 are a single color, and the end bars 106/114 are a single color. The bar connectors may also be the same color. According to one embodiment, the side bars 104/118 are blue, the attacher bars 110 are red, the end bars 106/114 are also red, and the bar connectors 108/116 are yellow. According to one embodiment, the straight bar connectors, if any, are green.

According to one embodiment, to provide added user convenience, portions of infant activity system kit 900 are factory preassembled. For example, end support segments 300 of FIG. 3A-3D may be preassembled at the factory prior to shipping. Upon reading the teachings of this specification, those with ordinary skill in the art will now understand that, under appropriate circumstances, considering issues such as preferred shipping size, intended use, etc., other kit arrangements, such as, for example, providing fully assembled units, etc., may suffice. Furthermore, upon reading the teachings of this specification, those with ordinary skill in the art will now understand that, under appropriate circumstances, considering issues such as cost, consumer demand etc., other end support arrangements, such as, for example, producing a unitary molded unit replacing the end bar set, attacher bar set, and connector set, etc., may suffice.

Turning to FIG. 10A, exemplary side bars 104/118 that are composed of more than one bar are shown. According to the depicted embodiment, the side bars 104/118 each include one straight bar connector 1002 and two side bar portions 1004. The side bar portions 1004 include spring fasteners 111 at each end and the straight bar connectors 1002 include holes 1003 for receiving a button of the spring fasteners 111. The holes 1003 and spring fasteners 111 can be used to connect and removable secure the side bar portions 1004 to the straight bar connector. FIG. 10A depicts the side bars 104/118 in dissembled and assembled configurations.

According to one embodiment, replacing the side bars 104/118 of FIG. 9 with the side bars 104/118 of FIG. 10A may be desirable. This may allow a child activity system 100 or kit 900 to be disassembled and stored/transported in a smaller container or configuration. This may also provide additional strength for the side bars 104/118. For example, in some embodiments, the side bars 104/118 of FIG. 10A are stronger than the side bars 104/118 of FIG. 9 due to the added support of the straight bar connector 1002. The strength of the side bars 104/118 composed of straight bar connectors 1002 and side bar portions 1004 may vary according to the thickness of the walls, the length, or the depth of the straight bar connectors 1002. For example, if the depth and length of the straight bar connectors 1002 is such that the side bar portions 1004 are received deeper into the straight bar connectors 1002, this may provide for added support and/or strength.

According to the depicted embodiment, the both side bar portions 1004 are removably attachable to the straight bar connectors 102. According to other embodiments, one or both of the side bar portions 1004 are permanently attached or bonded to the straight bar connector 1002. For example, it may be desirable to have one of the side bar portions 104 permanently attached to the straight bar connector 102 to limit the amount of assembly/disassembly required and/or limit the chance of losing a portion of the side bars 104/118.

According to one embodiment, similar to that mentioned above, the components of the side bars 104/118 may be colored and/or color coded. For example, according to one embodiment, the side bar portions 1004 are blue and the straight bar connectors 1002 are green. Other color schemes are also possible and may be desirable in some embodiments.

Turning to FIG. 10B exemplary embodiments of bar extenders 1010, 1012 are shown. According to the depicted embodiment, each side bar extender 1010, 1012 includes a straight bar connector 1002 and a bar extender portion 1008. The bar extenders 1010, 1012 may be placed on the end of a bar, such as side bars 104/118, end bars 106/114, or attacher bars 110 to extend the length of the respective bars. For example, the bar extenders 1010, 1012 may be added to the side bars 104/118 to extend the length of the child activity system 100. This may be desirable, for example, to provide a greater length for an infant 102 or child to practice walking. Similarly, the bar extenders 1010, 1012 may be added to the end bars 106/114 or attacher bars 110 to change the width of the upper graspable bar 101, the width of the lower base 109, or the height of the attacher bars 110.

FIG. 10B depicts bar extenders 1010, 1012 of two different lengths. According to one embodiment, the length of the straight bar connectors 102 is the same but the length of the bar extender portion 1008 varies. This may be desirable to provide flexibility in how much a bar is extended. These lengths are exemplary only and can vary greatly. Bar extenders 1010, 1012 of drastically different lengths are possible and may be desired.

According to one embodiment, bar extenders 1010, 1012 are sold in sets of four bar extenders 1010, 1012 all having the same length. For example, four long bar extenders 1012 may be sold together. According to another embodiment, bar extenders 1010, 1012 are sold in sets of two. For example, two short bar extenders 1010 may be sold together.

The bar extenders 1010, 1012 above are only exemplary. Other methods and mechanisms may be used for adjusting the length, height, or width of the child activity system 100, as illustrated by the attacher bars 110 of FIGS. 1-3D and 4B. For example, a similar telescoping bar could be used as side bars 104/118 or end bars 106/114 to allow for the adjustment of the dimensions of the child activity system 100.

Turning now to FIGS. 11 through 18, accessories, play features, and exemplary modes for the child activity system 100 will be discussed. The different accessories, play features, toys, and modes may help to provide additional utility to the child activity system 100 for even older children.

FIG. 11 shows a perspective view of a child activity system 100 with attachable play features 1102. The child activity system 100 is similar to the child activity system 100 of FIG. 1. However, the lower base 109 completely encloses an area due to a lower end bar 114 connected between the lower portion of the attacher bars 110 with T-bar connectors 1110. The child activity system 100 of FIG. 11 is exemplary only and could be replaced by the child activity system 100 of FIG. 1, for example.

According to the depicted embodiment, the attachable play features include straps 1104 attached to toys 1104. The toys 1103 may be a variety of toys including soft toys, balls, rings, or any other toys that may be enjoyable for a child. According to one embodiment, the straps 1104 are permanently attached to the toys 1103. For example, the straps 1104 may be sewed or glued to the toys, or attached in another permanent manner. According to another embodiment, the straps 1104 are removably attached to the types 1103, for example by the use of hook and loop fasteners. According to one embodiment, the straps 1104 may be selectively attached to a bar of the child activity system 110 and/or to a toy 1103. The straps 1104 may employ the use of hook and loop type attaching features to attach to toys 1103 or a bar of the child activity system 100. According to one embodiment, the straps 1104 are adapted to firmly hold a toy 1103 suspended while providing a breakaway safety feature if more than a predetermined weight is applied to the toy 1103. This may be desirable to limit the danger of a child getting caught in the toy 1103 or straps 1104.

Turning now to FIG. 12 perspective view of a child activity system 100 in one embodiment of a child walking training configuration is shown. According to the depicted embodiment, a toy 1103 is attached to the end of the child activity system 100. Accordingly, the toy 1103 has been located to draw a child 102 user into walking the length of child activity system 100. This may be desirable to provide motivation for a child 102 to attempt to walk using the child activity system.

FIG. 13A shows a side view of a basketball hoop 1300, according to one embodiment.

FIGS. 14A and 14B show the child activity system 100 resting two embodiments of activity mats 1402, 1404. FIG. 14A depicts the child activity system 100 resting on an activity mat 1402 having base fasteners 1403 to hold the child activity system 100 to the mat 1402. According to one embodiment, the base fasteners 1403 keep the child activity system 100 in substantially the same position when a child is doing walking training. For example, when a child is walking on the activity mat 1402 and applying a force to the upper graspable bar 103 of the child activity system 100 the base fasteners 1403 maintain the child activity system 100 on the activity mat 1402. Additionally, according to one embodiment, the activity mat 1402 provides an amount of padding to protect a child in case of a fall. This may enable child activity system 100 to be used safely on even very hard surfaces such as hardwood floors or cement.

FIG. 14B depicts the child activity system 100 resting on an activity mat 1402 having no base fasteners. According to one embodiment, the activity mat 1404 is a yoga mat. According to one embodiment, the activity mat 1404 is a may having a non-slip surface. A non-slip surface may provide similar benefits to the base fasteners 1403 of FIG. 14A. According to the depicted embodiment, the activity mat 1404 includes a design pattern 1405. More particularly, the depicted embodiment includes a football field design pattern 1405. Other embodiments may include other patterns, such as patterns for soccer fields, a hockey rink, a basketball court, baseball field, or any other sports court, field or rink. For example, if the activity mat 1402 had a soccer field design the child activity system 100 and could be used as a mini soccer field with the attacher bars 110 serving as goal posts. Other design patterns may include pictures or any other pattern that may be found on a mat, blanket, towel, or the like.

Features of the activity mats 1402, 1404 may be combined or selectively used in various embodiments. For example, the base fasteners 1403 of the activity mat 1402 may be included on the activity mat 1404 of FIG. 14B. Additionally, the activity mat 1402 of FIG. 14A may also include a non-slip surface and/or a design pattern. Various considerations may lead to varying designs of activity mats 1402, 1404. For example, according to one embodiment an activity mat 1402, 1404 may have a significant amount of padding to provide a softer mat for children, even on hard surfaces. According to other embodiments, very little padding may be needed if it is anticipated that the child activity system 100 will be used primarily on carpets or rugs. Additionally, less padding may be desired if it is desired that the activity mat 1402, 1404 be easy to store or transport. For example, yoga mats tend to provide greater padding and a non-slip surface but tend to be bulky and heavy. By using an activity mat 1402 having base fasteners 1403 the child activity system may still be held in place with a very light activity mat 1402.

According to one embodiment, the base fasteners 1403 comprise a cloth strap that is attached to the activity mat 1402 or other mat and which hooks around the corners of the lower base 109 of the child activity system 100. According to other embodiments, the base fasteners 1403 may comprise rigid or semi rigid hooks, hook and loop fasteners, strings for tying an activity mat 1402 to the lower base 109, or any other fastener known in the art that can connect an activity mat 1402 to the child activity system 100.

An additional feature providing slip resistance of the child activity system 100 is depicted in FIG. 14C. FIG. 14C shows a rubber pad 1406 inserted into a hole in an elbow bar connector 116, such as an elbow bar connector 116 at the corner of the lower base 109. The rubber pad 1406 is placed such that it will contact the ground and provide a non-slip grip to the ground. For example, the rubber pad 1406 may provide grip on hard surfaces as well as soft surfaces such as rugs or carpets. According to one embodiment a rubber pad 1406 is placed on an elbow bar connector 116 at each corner of the lower base 109. Other embodiments include a rubber pad 1406 in each bar connector on the lower base 109 of the child activity system 100.

According to one embodiment, the rubber pad 1406 retains itself within the hole of the bar connector 116. According to another embodiment, the rubber pad 1406 has an adhesive surface for sticking to a bar connector. Some embodiments may include bar connectors 116 having walls 1407 surrounding the rubber pad 1406 to hold the rubber pad 1406 in place when the child activity system 100 is slid across a surface.

Now turning to FIG. 15 a number of play accessories for use with child activity system 100 are shown.

According to one embodiment, the mini goals are formed of material similar to the bars and bar connectors of the child activity system 100.

Turning to FIG. 16A the child activity system 100 is configured into a large goal that may be used as a soccer, hockey, lacrosse, or other goal. According to this embodiment, a net 1601 attached to a child activity system 100, with a portion of the lower base 109 removed, is configured to look and act like a goal. The net 1601, as depicted, is attached to the bars of the child activity system 100 using fasteners 1603. According to one embodiment, these fasteners 1603 are hook and loop fasteners for easily attaching and removing the net 1601. According to another the fasteners 1603 are ring fasteners that clip the net 1601 to the child activity system 100. This embodiment, along with other embodiments, illustrates the utility of the child activity system 100 for even older children who are well past learning to walk.

FIG. 16B illustrates an embodiment of the invention to provide a ‘play tent’ (or ‘crawl-through’) structure for children's entertainment. Those familiar with child care and development should instantly appreciate this particular embodiment as children frequently enjoy building and hiding in forts or similar structures. According to the depicted embodiment, tent material 1605 is provided around the child activity system 100 system. Fasteners 1603 attach the tent material 1605 to bars of the child activity system 100.

According to one embodiment, the tent material 1605 is constructed from soft/flexible fabric or materials, as shown. Upon reading the teachings of this specification, those with ordinary skill in the art will understand that, under appropriate circumstances, considering issues such as intended use, etc., the inclusion of other cover features, such as, for example, themed indicia, storage pockets, windows, inflatable sections, soft padding including safety padding, etc., may suffice.

Turning now to FIGS. 17A and 17B exemplary embodiments of activity/play tables are shown. FIG. 17A shows a child activity system 100 having an end activity table 1701 mounted at each end. According to the depicted embodiment, the end activity table 1701 has a U shape and can support items for use/play by a child. According to one embodiment, the end activity tables 1701 are formed of a soft lightweight material, such as foam or plastic. According to one embodiment, the end activity tables 1701 are formed of EVA materials. The configuration depicted in FIG. 17A may be useful for children who are learning to walk. For example, a child may be placed within the upper graspable bar 103 with items placed on one or both of the end activity tables 1701. The child can then be motivated to stand and play by the items sitting on the end activity tables 1701 or be motivated to walk from one end activity table 1701 to the other.

FIG. 17B depicts a play table 1703 that covers the upper graspable bar 1703. The larger play table 1703 may be desirable for activities needing more space or for older children who are already walking. The play table 1703 could be used for a variety of activities, such as activities performed on any table. Once again, according to one embodiment, the play table 1703 may be formed of a soft lightweight material, such as foam or plastic. According to one embodiment, the play table 1703 is formed of EVA materials.

According to one embodiment, the above play/activity tables 1701/1703 may be attached to the bars of the child activity system 100 using fasteners 1603. These fasteners 1603 according to varying embodiments comprise hook and loop fasteners, ring fasteners, or other fasteners known in the art. The fasteners 1603 help to maintain the play/activity tables 1701/1703 in a substantially stable position, allowing children to perform a variety of activities thereon.

FIG. 18 illustrates additional play accessories for the child activity system. Shown is an infant harness 1801 and secured to the child activity system 100 with flexible bands 1801. The infant harness 1801, according to one embodiment, is used to provide additional support for an infant learning to use the present invention. For example, if the child has developmental challenges it may be that leg exercise would help the child even if the child is not strong or stable enough to support its own weight. Additionally, one embodiment of a toy accessory 1805 is also shown.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
