The present disclosure relates to extensible objects, and, in particular, an extensible object that is extensible so as to open a housing so as to expose the extensible object.
It is known to provide extensible objects, and, in particular, objects that are extensible and that break out of a housing. An example of this include some of the Hatchimals® line of products. Another example is a toy character that is made from a super-absorbent polymer (SAP), and which resides inside an egg-shaped housing. Immersion of the housing into water causes the toy character to absorb water and expand, eventually breaking out of the housing. However, some of the Hatchimals® products are able to grow, but only to a limited degree, while the toy character made from SAP has relatively limited play value once the breakout process is completed. It would be advantageous to provide a toy assembly with an extensible object that is capable of relatively large amounts of extension.
In an aspect, a toy assembly is provided, and includes a toy assembly housing, an extensible object inside the toy assembly housing, an extension mechanism, and an extension member power source. The extensible object includes a base, a first extension member that is movable relative to the base between a retracted position for the first extension member and an extended position for the first extension member, and a second extension member that is movable relative to the first extension member between a retracted position for the second extension member and an extended position for the second extension member. The extension mechanism is operable to drive the first extension member towards the extended position for the first extension member and to drive the second extension member towards the extended position for the second extension member. The extension mechanism is operatively connected to the second extension member via a lost motion connection having a selected amount of lost motion. The extension mechanism power source is operatively connected to the extension mechanism to drive the extension mechanism. When the extensible object is in a home position, driving of the extension mechanism by the extension mechanism power source drives the first extension member towards the extended position for the first extension member to break or open the toy assembly housing to expose the extensible object while consuming at least a portion of the lost motion in the lost motion connection so as to prevent movement of the second extension member towards the extended position for the second extension member, while breaking out of the toy assembly housing, by breaking or opening the toy assembly housing. Upon consuming an entirety of the lost motion in the lost motion connection, further driving of the extension mechanism by the extension mechanism power source drives both the first and second extension members towards the extended positions for the first and second extension members.
In another aspect, an extensible object is provided, and includes a base, a first extension member that is movable relative to the base between a retracted position for the first extension member and an extended position for the first extension member, a second extension member that is movable relative to the first extension member between a retracted position for the second extension member and an extended position for the second extension member, and an extension mechanism that is operable to drive the first extension member towards the extended position for the first extension member and to drive the second extension member towards the extended position for the second extension member. The extension mechanism includes at least one drum, a first extension drive cable connected between the at least one drum and the first extension member and passing over a pulley on the base, and a second extension drive cable connected between a second extension drive cable anchor point and the second extension member and passing over a second extension drive cable pulley on the first extension member. The extension mechanism power source is operatively connected to the at least one drum to rotate the at least one drum in a first rotation direction so as to wind the first extension drive cable onto the at least one drum, thereby driving the first extension member toward the extended position for the first extension member, which in turn drives movement of the second extension drive cable pulley, which in turn drives the second extension drive cable to drive movement of the second extension member relative to the first extension member.

The housing 12 may be made from any suitable material. In some embodiments the housing 12 may be made from a polymeric material and may include a first housing portion and a second housing portion that is removably mounted to the first housing portion, so as to permit a user to open the housing to access the extensible object 14.
In other embodiments, such as that which is shown, the housing 12 may be made to be breakable which a suitable ease, optionally during expansion of the extensible object 14. Referring to the view in
The housing 12 may be formed of any suitable natural or synthetic polymer composition, depending on the desired performance (i.e., breakage) properties. When presented in the form of an egg shell, as shown for example in
An example of a good material is a material that includes about 15-24 weight-% base polymer, about 1-5 weight-% organic acid metal salt and about 75-84 weight-% inorganic/particulate filler. It will be appreciated that a variety of base polymers, organic acid metal salts and fillers may be selected to achieve the desired performance properties. In one exemplary embodiment suitable for use in forming the housing 12, the composition is comprised of 15-24 weight-% ethylene-vinyl acetate, 1-5 weight-% zinc stearate and 75-84 weight-% calcium carbonate. While exemplified using ethylene-vinyl acetate, it will be appreciated that a variety of base polymers may be used depending on the desired performance properties. Alternatives for the base polymer may include select thermoplastics, thermosets and elastomers. For example, in some embodiments, the base polymer may be a polyolefin (i.e., polypropylene, polyethylene). It will be further appreciated that the base polymer may be selected from a range of natural polymers used to produce bioplastics. Exemplary natural polymers include, but are not limited to, starch, cellulose and aliphatic polyesters. While exemplified using calcium carbonate, it will be appreciated that an alternative particulate filler may be suitably used. Exemplary alternatives may include, but are not limited to, talc, mica, kaolin, wollastonite, feldspar, and aluminum hydroxide.
Suitable examples of fracture paths 16 are shown and described in U.S. Pat. No. 9,950,267B2, the contents of which are incorporated herein by reference.
The extensible object 14 may be configured to break the housing 12 from within the housing 12, as to expose the extensible object 14. The extensible object 14 may be in the form of a character, such as an animal, a robot, a person, a fictitious character, an anthropomorphic object or any other suitable type of character. Alternatively, the extensible object 14 may have a form that is not that of a character. In embodiments in which the housing 12 is in the form of an egg, the act of breaking the housing 12 will appear to the user as if the extensible object 14 is hatching from the egg, particular in embodiments in which the toy character 14 is in the form of a bird, or some other animal that normally hatches from an egg, such as a turtle, a lizard, a dinosaur, or some other animal.
The extensible object 14 is extensible, in the sense that it is capable of growing in at least one dimension. In the embodiment shown in
In the embodiment shown in
In order to permit movement between the various extension members, and between the first extension member 28 and the base 26, suitable bushing members shown at 38 in
Each extension member may be supported on the extension member preceding it towards the base 26. Thus, the second extension member 30 may be supported on a projection 39 on the fifth extension member 36, which in turn may be supported on a projection 39 on the fourth extension member 34, which in turn may be supported on a projection 39 on the third extension member 32, which in turn may be supported on a projection 39 on the first extension member 28, which in turn may be supported on a projection 39 on the base 26. The projection 39 is shown as being a cylindrical member in
An extension mechanism 40 is provided and is operable to drive the first extension member 28 towards the extended position for the first extension member 28 and to drive the second extension member 30 towards the extended position for the second extension member 30.
The extension mechanism 40 may include at least one drum 42. In the example shown in
In the present example, the extension mechanism 40 further includes a third extension drive cable 54 connected between a third extension drive cable anchor point 56 (e.g. a point on the base 26) and the third extension member 32 and passing over a third extension drive cable pulley 58 that is movable by movement of the first extension member 28 (and which is in the present example provided on the first extension member 28).
In the present example, the extension mechanism 40 further includes a fourth extension drive cable 60 connected between a fourth extension drive cable anchor point 62 (e.g. a point on the first extension member 28) and the fourth extension member 34 and passing over a fourth extension drive cable pulley 64 that is movable by movement of the first extension member 28 (and which is in the present example provided on the third extension member 32).
In the present example, the extension mechanism 40 further includes a fifth extension drive cable 66 connected between a fifth extension drive cable anchor point 68 (e.g. a point on the third extension member 32) and the fifth extension member 36 and passing over a fifth extension drive cable pulley 70 that is movable by movement of the first extension member 28 (and which is in the present example provided on the fourth extension member 32).
The aforementioned pulleys may optionally be rotatable, or may alternatively be stationary members that are of suitably low friction not to abrade the cables sliding thereon.
In the present example, the first, second, third, fourth and fifth extension drive cables are in the form of ribbons so as to have strength while maintaining a low thickness. However, the extension drive cables may have any other suitable form.
In the present example, the extensible object 14 is a representation of a character (a bird), and includes a representation of feet 74 of the character on the base 26, a representation of a torso 76 of the character on the third extension member 32, and includes a representation of a head 78 of the character on the second extension member 30.
An extension mechanism power source 72 is operatively connected to the at least one drum 42 to rotate the at least one drum 42 in a first rotation direction D1 shown in
The extension mechanism power source 72 may be any suitable power source. For example, it may be an electric motor that is operatively connected to the at least one drum 42 via a plurality of gears 80. The electric motor may be driven by one or more batteries 73 (shown in dashed lines in
In some embodiments, the extension mechanism 40 further includes a retraction drive cable 82 connected between the at least one drum 42 and the second extension member 30. Idler pulleys 83 are provided as needed to route the retraction drive cable 82 to avoid interference with other components. This is best seen in
While the provision of the retraction drive cable 82 ensures positively that the extensible object 14 is driven by the extension mechanism power source 72 to move to the retracted position for the extensible object 14, it is alternatively possible to not provide the retraction drive cable 82. In such an embodiment, rotation of the at least one drum 42 in the second rotational direction D2 pays out the first extension drive cable 44 from the at least one drum 42, thereby and permits gravity to drive the second extension member 30 towards the retracted position for the second extension member 30, which in turn drives movement of the first extension drive cable pulley 46, which in turn drives the first extension drive cable 44 to drive movement of the first extension member 28 relative to the first extension member 30.
In
A controller 84 may be provided to control the operation of the extension mechanism power source 72. An encoder 86 may be provided and is connected to the controller 84 to send signals thereto. The encoder 86 may also be connected to the at least one drum 42 by one or more gears 88 as shown, so as to control the rotational speed of the encoder wheel to suit the needs of the controller 84. The controller 84 may control the speed and direction of the electric motor.
In the embodiment shown in
In the embodiment shown, the extension mechanism 40 is operatively connected to the second extension member 30 via a lost motion connection 92 having a selected amount of lost motion. The lost motion connection 42 facilitates the breakout of the extensible object 14 from the housing 12. More specifically, it will be understood that a greater amount of torque is needed to drive the movement of all the extension members relative to one another, than is required to drive the first extension member 30 while it supports the other extension members. Accordingly, it is easier for the electric motor to drive the extension members when there is a lost motion connection 92 in order to break the housing 12 (or even just to open the housing in certain embodiments). Providing the lost motion connection 92 permits this while still permitting the electric motor to still be used to drive the second extension member (and the third, fourth and fifth extension members once the lost motion in the lost motion connection 92 is consumed.
The lost motion connection 92 may be formed in any suitable way. For example, the lost motion connection 92 in the present example includes an excess amount of length of the third extension drive cable 54 between the base 26 and the third extension member 32, such that there is a selected amount of slack in the third extension drive cable 54 when the first and third extension members 28 and 23 are in the retracted positions for the first and third extension members 28 and 32, and wherein the third extension member 32 is supported against a limit member 39 on the first extension member 28 so as to be driven thereby and to drive the second extension member 30 even when there is slack in the third extension drive cable 54.
The second extension drive cable 48 drives movement of the second extension member 30 relative to the first extension member 28 upon consumption of the lost motion in the lost motion connection 92.
As a result, the extensible object 14 may be extensible along two axes. The axes 102 and 24 may be perpendicular to one another. As a result of having the two axes 24 and 102 be non-coaxial with one another, the extensible object 14 is able to grow in two dimensions, optionally by means of a single power source, such as a single electric motor.
In the examples shown in
While the third-axis extension members 120 and 124 extend along a third axis 122 that is co-axial with the second axis 102, it is alternatively possible for the third axis to be non-coplanar with the first and second axes 24 and 102. For example, the three axes may all be orthogonal to one another. As a result of having the three axes 24, 102 and 122 be non-coplanar with each other, the extensible object 14 is able to grow in three dimensions, optionally by means of a single power source, such as a single electric motor.
In the example shown in
In the embodiments shown in
In the embodiments shown and described herein, it will be noted that the toy assembly 10 may be provided with a mechanism to rotate the extensible object 14 while it is in the housing 12 during the breakout process. For example, the extensible object 14 may stand on a platform that is rotatable, and which is driven by a platform drive source, such as an electric motor that is separate from the extension mechanism power source 72. Operation of the platform drive source can rotate the extensible object 14 to a position, at which point the extension mechanism power source 72 can drive the extensible object 14 to extend by a small amount in order to break the housing 12 slightly, (thereby appearing as if a character is trying to peck its way out, or otherwise break its way out of the housing 12. The extension mechanism power source 72 can then retract the extensible object 14, at which point the platform drive source can drive the extensible object 14 to a new position, in order to extend itself again, by a small amount, so as to appear that the character is attempting to break out in a different location. After a plurality of small extensions and subsequent retractions, and rotations to new positions, the extension mechanism power source 72 may be driven to extend the extensible object 14 more fully so as to break out of the housing 12.
While it has been described for the toy assembly housing 12 to be broken by the toy character 14 during a breakout process, it will be noted that this need not be the case. The breakout process could alternatively involve the toy character 14 opening the toy assembly housing 12, such as by pushing open a lid on the toy assembly housing 12 that is hingedly connected to a lower portion of the toy assembly housing 12, or by popping off a lid that is snap fit to a lower portion of the toy assembly housing 12.
Persons skilled in the art will appreciate that there are yet more alternative implementations and modifications possible, and that the above examples are only illustrations of one or more implementations. The scope, therefore, is only to be limited by the claims appended hereto and any amendments made thereto.
