DETAILED DESCRIPTION

A posable toy figure is disclosed. The posable figure includes some aspects that are rigid and some aspects that are flexible. The user is able to manually manipulate the toy figure into a pose, and the toy figure maintains that pose until the pose is deliberately changed.



FIG. 1A is a side block diagram of an exterior of an example of a limb structure 110 in the Y-Z plane. FIG. 1B is a side cross-sectional view of the limb structure 110 in the Y-Z plane. FIG. 1C is a side cross-sectional view of the limb structure 110 along the line C-C′ of FIG. 1A and in the X-Z plane. FIGS. 1A-1C are referred to in the discussion below.


The limb structure 110 may be used to form a posable toy figure (such as the toy figure 200 shown in FIGS. 2A and 2B). The limb structure 110 includes a flexible support member 112 that is enclosed in a pliable member 114. The flexible support member 112 is made from any rugged material that may be repeatedly bent into different shapes without breaking or wearing. For example, the flexible support member 112 may be a metal wire, such as an iron and/or stainless steel wire.


The pliable member 114 is made of any material that is capable of enclosing the flexible support member 112. For example, the pliable member 114 may be made of rubber, flexible polyvinyl chloride (PVC), or a flexible fabric material. The pliable member 114 may be a tube structure or a hollow cylinder. The pliable member 114 may be open at an end 113a and/or an end 113b. In implementations in which the pliable member 114 is open at the end 113a and/or the end 113b, the pliable member 114 encloses the flexible member 112 by encircling the flexible member 112. Moreover, the pliable member 114 may enclose the flexible member 112 by enclosing or surrounding less than all of the flexible member 112. In other words, the pliable member 114 is not required to surround the entire flexible member 112. Although the pliable member 114 is able to move with the flexible member 112 and may touch the flexible member 112 as the member 112 moves, as shown in FIG. 1C, the pliable member 114 is separate and distinct from the flexible member 112. For example, the pliable member 114 is not a coating that is permanently part of the flexible member 112.


The limb structure 110 also includes a first rigid body 120 and a second rigid body 130. The first rigid body 120 and the second rigid body 130 are hollow bodies that enclose respective portions 116, 118 of the pliable member 114. FIG. 1D shows the first rigid body 120 and the second rigid body 130 prior to attachment to the limb structure 110. The first rigid body 120 includes shell parts 120a, 120b and the second rigid body 130 includes shell parts 130a, 130b. Each of the shell parts 120a, 120b, 130a, 130b is made of a durable and rigid solid material, such as, for example, molded plastic or metal. The shell parts 120a, 120b, 130a, 130b are shaped such that when the shell part 120a is joined to the shell part 120b, a hollow rigid body (the first rigid body 120) is formed. Similarly, when the shell part 130a and the shell part 130b are joined they form a hollow rigid body (the second rigid body 130).


To attach the rigid bodies 120 and 130 to the limb structure 110, the shell parts 120a, 120b and the shell parts 130a, 130b are moved toward each other and toward the limb structure 110. The first portion 116 of the limb structure 110 is captured between the shell parts 120a and 120b. The second portion 118 of the limb structure 110 is captured between the shell parts 130a and 130b. The shell parts 120a and 120b are joined while the first portion 116 is captured between the parts 120a and 120b to form the first rigid body 120. The shell parts 130a and 130b are joined while the second portion 118 is captured between the parts 130a and 130b to form the second rigid body 130. The shell parts 120a and 120b, and the shell parts 130a and 130b may be joined to each other by, for example, sonic or ultrasonic welding, gluing, or any other joining technique that creates a permanent bond.


The first rigid body 120 and the second rigid body 130 are separate and distinct rigid bodies and at least part of the pliable member 114 is exposed and visible from the exterior of the limb structure 110 after the first rigid body 120 and the second rigid body 130 are attached to the limb structure 110. In FIG. 1A, the portion labeled as 119 is an example of a part of the pliable member 114 is that is exposed when the first rigid body 120 and the second rigid body 130 are attached to the limb structure 110. The portion 119 is between the first rigid body 120 and the second rigid body 130.


The rigid bodies 120 and 130 do not change shape after being attached to the limb structure 110. The limb structure 110 does not bend at the portions 116 and 118, which are the portions that are captured by the rigid bodies 120 and 130, respectively. However, portions of the limb structure 110 that are not enclosed in the rigid body 120 or the rigid body 130 can change shape after the rigid bodies 120 and 130 are attached. For example, the portion 119 may be bent by a user while the rigid bodies 120 and 130 are attached to the limb structure 110. The user may grasp the limb structure 110 at each of ends 113a and 113b and cause the limb structure 110 to bend by changing the straight (zero angle) form of the portion 119 shown in FIG. 1A to a non-zero angle. The portion 119 maintains the bent shape after the user stops applying force. In this way, the limb structure 110 is posable.


The first rigid body 120 also includes a connection interface 122 that extends from an exterior surface 124 of the first rigid body 120. The connection interface 122 allows the limb structure 110 to connect to a separate body portion (not shown in FIG. 1A) to form a toy figure such as the toy figure 200 of FIGS. 2A and 2B. The connection interface 122 may be, for example, a ball connection or a post that connects to a corresponding socket on the separate body portion. Because the connection interface 122 extends outward from the surface 124, the connection interface 122 occupies little to no space in the interior of the first rigid body 120. Thus, the limb structure 110 may be connected to another structure to form a larger posable figure (such as the figure 200 of FIGS. 2A and 2B), but the interior of the first rigid body 120 has enough space to enclose the first portion 116 of the limb structure 110. The external arrangement of the connection interface 122 allows the first rigid body 120 to be a relatively small element, thereby providing for more design options for the posable figure.


Referring to FIG. 2A, a side block diagram of an exterior of an example of an assembled posable figure 200 is shown. FIG. 2B shows a cross-sectional view of the posable figure 200. The assembled posable figure 200 includes two limb structures 210a and 210b. Each limb structure 210a, 210b is similar to the limb structure 110 of FIGS. 1A-1D.


The toy figure 200 is a humanoid action figure. The toy figure 200 includes a torso body 220a and a pelvis body 220b, both of which are hollow rigid bodies. The pelvis body 220b includes a connection interface 222b that is received and held by a corresponding connection interface 222a. The connection interface 222a is part of the torso body 220a. The connection interface 222b extends outward from an exterior surface 224b of the pelvis body 220b. The connection interface 222a is recessed into the torso body 220a. The torso body 220a also includes an additional connection interface 229 that is used to connect an external feature such as, for example, a head element (not shown) to the toy figure 200. The additional connection interface 229 may be a post or ball that extends outward from an external surface 224a the torso body 220a.


As compared to a connection interface that protrudes into the pelvis body 220b, the connection interface 222b allows more space in the interior of the pelvis body 220b. The arrangement and configuration of the connection interfaces 222a and 222b allow the pelvis body 220b to be relatively small, and smaller than the torso body 220a. This provides the opportunity for a more realistic design for the pelvis body 220b.


The connection interface 222a and the connection interface 222b may form a snap connection. For example, the connection interface 222b may be a ball and the connection interface may be a socket that includes an opening that is a partial sphere. In these implementations, the ball snaps into the spherical opening. In other implementations, the connection interface 222a and the connection interface 222b form a friction fit connection. Regardless of the type of connection formed by the interfaces 222a and 222b, the pelvis body 220b and the torso body 220a are connected at the point of manufacture and are intended to remain connected during use. However, the pelvis body 220b and the torso body 220a may be rotatable relative to each other.


The torso body 220a includes arm openings 225a_1 and 225a_2. The arm openings 225a_1 and 225a_2 pass through respective sidewalls of the torso body 220a. The arm opening 225a_1 is formed in a first sidewall 227a_1, and the arm opening 225a_2 is formed in a second sidewall 227a_2 that is opposite to the sidewall 227a_1. A flexible support member 212a passes through the torso body 220a, with one end of the flexible support member 212a passing through each of the arm openings 225a_1, 225a_2. The flexible support member 212a is any flexible and durable material that is capable of being repeatedly shaped and holding that shape. For example, the flexible support member 212a may be a metal wire.


A portion of the flexible support member 212a is enclosed by a pliable member 214a_1, and another portion of the flexible support member 212b is enclosed by a pliable member 214a_2. Together, the flexible member 212a, and the pliable members 214a_1 and 214a_2 form the limb structure 210a. The pliable member 214a_1 extends through the arm opening 225a_1, and the pliable member 214a_2 extends through the arm opening 225a_2. The arm openings 225a_1, 225a_2 are sized such that the respective pliable members 214a_1, 214a_2 remain in the arm openings 225a_1, 225a_2 during ordinary use.


The pliable members 214a_1 and 214a_2 are made of any flexible material capable of enclosing the flexible support member 212a. For example, the pliable members 214a_1 and 214a_2 may be made from rubber or a flexible fabric material. The pliable members 214a_1 and 214a_2 are distinct and separate from the flexible member 212a. However, the pliable members 214a_1 and 214a_2 are able to move with the flexible support member 212a but do not rip or break when the flexible support member 212a moves. In the example toy figure 200, the pliable members 214a_1 and 214a_2 are separate pliable members that do not touch each other within the torso body 220a. However, in other implementations, a single, unitary pliable member that passes through both arm openings 225a, 225b and encloses the flexible support member 212a is used instead of the pliable members 214a_1 and 214a_2.


The toy figure 200 also includes the pelvis body 220b. The pelvis body 220b includes leg openings 225b_1 and 225b_2 that pass through respective sidewalls 227b_1 and 227b_2. Each end of a flexible support member 212b passes through one of the leg openings 225b_1, 225b_2. The flexible support member 212b is any flexible element that can be shaped repeatedly without breaking and is able to maintain a formed shape until being intentionally re-shaped. For example, the flexible support member 212b may be a metal wire.


The flexible support member 212b is enclosed by a pliable member 214b. The pliable member 214b is a unitary pliable member. One end of the pliable member 214b extends through each of the leg openings 225b_1, 225b_2. Together, the pliable member 214b and the flexible member 212b form the limb structure 210b.


The toy figure 200 also includes hollow rigid body members 230-237, each of which is a separate and distinct body member. Each of the body members 230-237 is similar to the second rigid body 130 (FIGS. 1A, 1B, and 1D). Thus, each of the body members 230-237 is formed from at least two shell portions. Each of the rigid body members 230-233 encloses a portion of the limb structure 210a. Each of the rigid body members 234-237 encloses a portion of the limb structure 210b. Portions 250 and 251 of the pliable member 214a_1, portions 252 and 253 of the pliable member 214a_2, and portions 255-258 of the pliable member 214b are exposed when the toy figure 200 is fully assembled. The toy figure 200 may be bent at any of the portions 250-257 because these portions are not in a rigid body. In this way, the toy figure 200 is posable.


The toy figure 200 may have additional features. For example, the body members 234 and 237 may be sized in the X direction such that the toy figure 200 is able to stand upright (along the Z direction in this example). Moreover, one or more of the sides of the body members 234 and 237 may be beveled to provide for enhanced posing in the upright position.



FIG. 3 is a flow chart of an example of a process 300 for manufacturing a limb structure that may be used as part of a toy figure, such as the toy figure 200 (FIGS. 2A and 2B). The process 300 is discussed with respect to the limb structure 110 of FIGS. 1A-1D.


The flexible support member 112 is provided (310). The flexible support member 112 is at least partially enclosed in the pliable member 114 to form the limb structure 110 (320). For example, in some implementations, the pliable member 114 is a tube and the flexible support member 112 is enclosed in the pliable member 114 by inserting the flexible member 112 into an end of the tube. In some implementations, the flexible support member 112 is placed in a mold, and the pliable member 114 is formed by injecting a pliable material into the mold. In these implementations, the flexible support member 112 is overmolded.


The portion 116 of the posable limb structure 110 is captured in the first rigid body 120 (330). In some implementations, and as shown in FIG. 1D, the rigid body 120 includes two shell parts 120a and 120b. The shell parts 120a and 120b are initially separated from each other along the Z direction. To capture the portion 116 in the body 120, the shell parts 120a and 120b are aligned with each other along the Z direction. The shell parts 120a and 120b are moved toward each other and toward the portion 116 until the shell parts 120a and 120b touch each other and capture the portion 116 between the shell parts 120a and 120b. The shell parts 120a and 120b are permanently joined to each other by any technique capable of forming a permanent bond between the shell part 120a and the shell part 120b. In implementations in which the shell parts 120a and 120b are made of plastic, ultrasonic welding may be used to create the permanent bond. Ultrasonic welding includes applying pressure to the shell parts 120a and 120b and then applying ultrasonic acoustic vibrations to the shell parts 120a and 120b to create a solid-state weld that permanently joins the shell parts 120a and 120b.


The portion 116 may be captured in the first rigid body 120 in another manner. For example, the first rigid body 120 may be pre-formed as a unitary hollow body with two openings. In these implementations, the limb structure 110 is passed through both openings until the portion 116 is within the first rigid body 120. Moreover, in some implementations, the first rigid body 120 is a molded hollow piece. In implementations that include more shells that are permanently joined to the form the first rigid body 120, each of the shells may be a molded piece.


The portion 118 is captured in the second rigid body 130 (340). In some implementations, and as shown in FIG. 1D, the rigid body 130 includes two shell parts 130a and 130b. The shell parts 130a and 130b capture the portion 118 and are permanently bonded. The shell parts 130a and 130b may be permanently bonded in a manner similar to the manner in which the shell parts 120a and 120b are connected. In other implementations, the second rigid body 130 is pre-formed and the portion 118 is captured in the second rigid body member by passing the limb structure 110 into an opening in the second rigid body 130.


In some implementations, additional rigid bodies are attached to the limb structure 110. However, regardless of how many rigid bodies are attached, the limb structure 110 includes portions (such as the portion 119) that are not covered or captured by a rigid body. The limb structure 110 is able to bend at the portions that are not captured by a rigid body and is thus posable.


In some implementations, the rigid body 120 is connected to another rigid body (such as the torso element 220a of FIGS. 2A and 2B) to form a toy figure that has a humanoid appearance. The toy figure may have a form other than a humanoid. For example, the toy figure may resemble a vehicle, an insect, an animal.


Other implementations are within the scope of the claims.
