Patent Application
20060228985
The present disclosure relates generally to movable toys, and more specifically, to joints of action figures and dolls. Movable action figures and dolls (e.g., action figures having shoulder/elbow joints, hip/knee joints, waist joints, etc.) can provide imaginative fun for children. Movable joint motion allows a child to configure a toy as he or she chooses. Examples of such toys are disclosed in U.S. Pat. Nos. 3,277,602; 3,628,282; 3,988,855; 4,274,224; 4,968,282; 5,989,658; and 6,435,938, the disclosures of which are incorporated herein by reference. Typically, it is desirable that the joints and other structures which enable relative movement be durable, enable the desired range of movement, and be relatively inexpensive to manufacture.
The present disclosure is directed to a movable toy, such as a doll or action figure, having a joint or like mechanism that enables relative movement. In some embodiments, the toy includes two or more body part members interconnected by a joint having a plug and a socket for receiving the plug. The socket includes one or more protrusions, against which the plug is urged to create friction between the plug and socket, thereby restricting joint motion.
Typically, a given joint is configured to enable one part of the toy (e.g., a body part member) to be moved relative to another, and then maintain the relative position of the parts once a desired position has been achieved. For example, toy 10 has a first body part member, such as torso 16, and a second body part member, such as pelvis 18. One of joints 14 forms a waist joint 20, defined between torso 16 and pelvis 18 to enable relative motion between the torso and pelvis. The remaining description will focus primarily on the waist joint, though it should be appreciated that the structures and mechanisms to be discussed may be implemented in other locations on a doll, and in movable toys other than dolls.
As shown in
In some embodiments, socket portion 24 has a support surface or wall portion 32 with several protrusions 34 extending therefrom that form socket contact regions 28. Joint 14 may be adapted so that plug portion 22 is urged into contact with protrusions 34 so as to create friction therebetween. The body part members are therefore able to maintain their relative positions during play.
As previously mentioned, joint 14 is comprised of socket portion 24 and plug portion 22. These portions engage with one another to control relative movement between torso 16 and pelvis 18 (e.g., by inhibiting relative movement through friction), or other appropriate body part members 12. Plug contact region 30 articulates within socket portion 24. In some embodiments, plug contact region 30 is spherical and mates with a cylindrically shaped socket portion, as shown in
In some embodiments, such as shown in
In the depicted examples, insert 36 has an opening sized to accommodate passage of a shaft 58 that extends away from operative surface 30 of plug portion 22. Typically, the opening is smaller than the diameter of operative surface 30, so as to maintain the operative surface captured and held within socket portion 24. Also, the area around the opening typically is adapted to contact the operative surface of plug portion 24 and urge it toward the frictional contact surfaces of the socket.
Socket portion 24 typically includes one or more protrusions 34 extending inward toward the operative surface of plug portion 22. The protrusions may be formed on the torso of the doll, as indicated in the figure, or may be manufactured as a separate piece to be inserted during assembly. Protrusions 34 typically are adapted to provide the friction described above, so as to inhibit movement (e.g., rotation) of plug portion 22 within socket portion 24, thereby inhibiting relative movement of the respective members of the toy (e.g., body part members 12). As shown in
The protrusions themselves may also be aligned towards one another so that the protrusions approach operative surface 30 from different directions, or they may extend parallel to one another from the socket wall. Furthermore, the ends of the protrusions may be angled or formed with a concave contour to complement the concave operative surface of plug portion 22. In addition, the operative surface of the plug portion may be provided with grooves for receiving the protrusions, so as to provide desired constraints on the relative movement permitted between the parts of the toy.
As shown in
Socket portion 24 may have additional structure to secure socket insert 36 within its respective body part member 12. As shown in
Similar to torso 16, pelvis 18 may be formed from a pelvis front 50 and a pelvis back 52 that form an internal pelvis compartment 54, as shown in
Plug portion 22 may be anchored to the body part member opposite that in which socket portion 24 is mounted, such as to pelvis 18. As shown in
In
Once the components of toy 10 have been aligned in their appropriate positions, as previously discussed, the front and back portions of torso 16 and pelvis 18 are joined together using any suitable method, such as those generally known in the art. In some embodiments one half of a body part member includes pins or posts 68, while the other half of the body part member includes receptacles 70 that receive posts 68. In such a configuration, posts 68 are simply aligned with, and pressed into, receptacles 70 to snap the two halves together.
It is believed that the disclosure set forth above encompasses multiple distinct inventions with independent utility. While each of these inventions has been disclosed in its preferred form, the specific embodiments thereof as disclosed and illustrated herein are not to be considered in a limiting sense as numerous variations are possible. The subject matter of the inventions includes all novel and non-obvious combinations and subcombinations of the various elements, features, functions and/or properties disclosed herein. Similarly, where any claim recites “a” or “a first” element or the equivalent thereof, such claim should be understood to include incorporation of one or more such elements, neither requiring nor excluding two or more such elements.
Inventions embodied in various combinations and subcombinations of features, functions, elements, and/or properties may be claimed through presentation of new claims in a related application. Such new claims, whether they are directed to a different invention or directed to the same invention, whether different, broader, narrower or equal in scope to the original claims, are also regarded as included within the subject matter of the inventions of the present disclosure.
This is a continuation application of U.S. patent application Ser. No. 10/712,498, filed on Nov. 12, 2003, which in turn claims priority under 35 U.S.C. 119(e) to U.S. Provisional Patent Application No. 60/426,021 entitled “Frictional Ball-And-Socket Waist Joint,” filed Nov. 12, 2002. Both applications are incorporated herein by reference in their entirety for all purposes.
