INVENTOR. HERBERT THOR/v BY w Fw g DOLL LEG CONNECTOR The present invention relates to toy dolls and, in particular, to connecting mechanisms for rotatably securing a limb of the doll to its torso.

Numerous connecting members of the above type have been previously proposed and such mechanisms include those which have to be built or molded into the legs and body of the doll in a relatively expensive manufacturing process. Other methods of connecting the limbs of the doll to its torso include molding annular slots in the limb which slots are adapted to be snap fitted in complementary apertures formed in the torso. While such connecting systems are relatively inexpensive, they are of course, not very permanent and thus the limb can be readily severed from the torso by a child, even during normal play.

Accordingly, it is an object of the present invention to provide a relatively inexpensive and simply constructed connecting mechanism for securing a limb to the torso of a toy doll.

It is another object of the present invention to secure a limb to the torso of a toy doll in a convenient and substantially permanent manner while permitting adjustment of the relative position of the limb with respect to the torso.

Another object of the present invention is to rotatably connect a limb to the torso of a toy doll or the like and to provide predetermined adjustable positions in which the limb may be set during play.

In accordance with an aspect of the present invention, the limb connector mechanism is provided for use in a toy doll having a torso and a limb, to be connected thereto, including an opening at one end thereof defined by an annular flange extending outwardly from the limb and having a rim formed at its free end. A mounting frame is secured in the torso and has a generally rectangular aperture adjacent the end thereof to be secured to the limb. A generally circular disk, having a larger diameter than the limb opening and a generally rectangular aperture therein is positioned inside the limb adjacent the inner surface of the rim. A bearing cap is positioned between the outer surface of the rim and the frame in engagement with both the rim and the frame and has an annular wall portion surrounding the outer surface of limb flange. The cap also has a circular opening therein located in alignment with the apertures in the disk and the frame and the annular wall of the cap has recesses therein complementary to and receiving key members formed on the exterior surface of the limb flange to maintain the cap in a predetermined position with respect to the limb.

A relatively flat connecting member, having a head portion inside the limb adjacent the disk, includes an elongated stem portion extending through the aligned apertures in the disk, frame, and cap, with a shouldered portion facing the frame, formed at its free end. A helical compression spring surrounds the stem with one end thereof engaged against the frame and the other end thereof engaged against the stems shoulder to urge the washer and frame towards each other and to hold the limb and cap therebetween. As a result, the limb is firmly connected to and rotatably mounted on the frame and torso. The cap and frame members are provided with a plurality of cooperating detents and complementary recesses, located at predetermined positions which define a plurality of stable fixed positions into which the limb may be rotated. In the preferred embodiment of the invention three such cooperating detents and recesses are provided which are located in positions corresponding to the standing and sitting positions of the toy doll.

The above, and other objects, features and advantages of this invention, will be apparent in the following detailed description of an illustrative embodiment thereof which is to be read in connection with the accompanying drawings, wherein:

FIG. 1 is a partial front view, partly in section, of a toy doll having its legs connected to its torso by a connecting mechanism constructed in accordance with an embodiment of the present invention;

FIG. 2 is an exploded perspective view of the connector mechanism of the present invention; and

FIG. 3 is a sectional view illustrating the manner of installation of the disk and connector member in the limb.

Referring to the drawings in detail, and initially to FIG. 1, it will be seen that a toy doll 10 has a torso section 12 and legs 14 operatively connected to the torso by connecting mechanisms 16. The latter rotatably secure the limbs to the torso which has a pair of enlarged openings 18 adjacent the point of connection thereof with legs 14, and the connecting mechanism 16 extends therethrough for connection to a frame 20.

Frame 20 comprises a pair of generally U-shaped members 22 and 24, secured at right angles to each other, and is pivotally mounted in the torso by stud members 26 in the front and rear of the torso (only one of which is seen if FIG. 1), which extend through apertures 28 in the legs 30 of frame member 24. Frame member 22 includes leg portions 32 adjacent openings 18, and each leg portion has a generally rectangular aperture 34 therein.

Legs 14 are hollow molded plastic members and each have an opening 36 therein which is defined by an upstanding flange portion 38, molded into the leg, and an inwardly extending annular rim 40 formed at the upper edge of the flange.

As seen in FIGS. 1 and 3, a portion of connector mechanism 16 is received within openings 36, to hold legs 14 adjacent their associated frame leg member 32. To accomplish this, each connector mechanism 16 is provided with a circular disk 42 having a larger diameter than openings 36. This disk or washer, is provided with a generally sector-shaped notch 44 which facilitates insertion of the disk within opening 36, as is more fully described hereinafter. In addition, disk 44 includes a rectangular aperture 46 which is complementary to the aperture 34 formed in legs 32 and receives an elongated connecting member 48 therethrough. The latter is a generally flat member, rectangular in crosssection, having an enlarged head portion 50, of smaller diameter than aperture 36 but having a larger major dimension than the aperture 46. Connector 50 also includes a stem portion 52 which extends through aperture 46 and through opening 34 in frame member 32 to provide a common interconnecting member between the limb'l4 and torso l2.

Prior to insertion of disk 42 in limb l4, stem 52 of connector 48 is inserted through aperture 46 and the disk is positioned in aperture 36 as illustrated in FIG. 3. As seen therein, rim 38 is received in notch 44 so that disk 40 may be readily inserted in leg 14 through aperture 36 by placing it edgewise in the aperture and moving the disk inwardly with respect to the leg. The stem 52 is held firmly during the installation operation so that it does not fall into the hollow leg 14. After disk 42 is thus inserted in leg 14, the stem 52 is pulled tightly so that the disk 42 is moved into engagement with the inner surface 54 of rim 40.

A bearing or cap member 56 is then positioned over rim 40 and flange 38. This cap member is generally circular and has an annular side wall or flange 58 which surrounds flange 38. A generally circular opening 60 is formed in the cap so that the cap may receive and pivot about stem 52. In addition, flange S8 is provided with at least one, and preferably two, recesses 62 therein which receive enlarged bosses or key members 64, formed at predetermined locations on the outer periphery of flange 38. These key members are preferably of different sizes, with each of the recesses 62 in the flange 58 being of respective complementary sizes so that the cap can only be positioned on the limb in one configuration, for reasons more fully described hereinafter.

With disk 42, connector 48, and cap 62 secured in this manner, stem 52 isinserted through aperture 34 of its associated frame leg 32, with the cap 62 in bearing relation against the outer surface 66 or rim 38 and the inner surface 68 of leg 32. A helical compression spring 70 is then placed about the stem 52 of connector 48 with one end thereof in bearing engagement against the outer surface 72 of leg 32 and its other end engaged in a notch or shoulder 74 formed in the enlarged head portion 76 of stem 52.

As seen in FIG. 1, the side 78 of head 76 extends beyond the side 80 of stem 52 to define enlarged head 76 and notch 74. In this manner disk 42 is urged towards frame member 32 to hold rim 36 and cap 56 tightly therebetween. Since rim 40 defines a generally circular aperture and since cap 62 has a circular aperture therein, it is seen that the limb 14 is rotatably mounted on stem 52 by the arrangement of the present invention. Stem 52, being secured in the rectangular recess 34 of frame leg 32, is held in a fixed position with respect to the torso and does not rotate upon rotation of the leg 14. Similarly, disk 42 does not rotate since it is fixed in position by the engagement of the fixed stem 52 in its rectangular opening 46. Since cap 62 is fixed with respect to leg 14 by the engagement of keys 64 with its recess 62, the cap will not rotate with respect to the plastic leg 14 but rather, its outer surface 86 provides a rotational bearing surface against the inner surface 68 of theieg 32. As a result the toy doll will have a longer life since metal to metal bearing surfaces are provided as opposed to the plastic to metal bearing surface of previously proposed arrangements which cause the plastic to errode, and thus eventually destroy the integral connection between the limb and the torso.

As seen in FIG. 2, cap 56 is provided with a plurality of recesses 88 on its outer surface 66 while the inner surface 68 of legs 32 are provided with a complementary number of corresponding detents 90. These detents are located on the cap and leg to define the sitting and standing positions of the leg with respect to the torso. When these detents are engaged in their cooperating recesses, the leg is held firmly in position and cannot be moved without the application of a predetermined force. Thus, inadvertent and undesired swinging movement of the leg 14 is avoided, but ready adjustment of the leg positions is provided. Moreover, the recesses 88 on cap 56 are located in predetermined rela tion to recesses 62 so that the sitting and standing position of the doll are automatically set when the connector mechanism 16 is assembled.

It is thus seen that frame 20 is thereby securely connected to each of the limbs 14 by the connector members 16 of the present invention to provide a stable platform for the torso of the doll. As mentioned above, the torso is connected to the frame by the stud members 26 which are received in recesses 28 of the legs of frame member 30. This provides a pivotal mounting of the torso on frame member 20, and thus legs 14 which permits the torso to be rocked side to side about the pivoted axis formed by the lugs 26. This may be accomplished by the provision of an oscillating mechanism such as an electric motor mounted in the torso and having an eccentric cam or the like secured to its output shaft and operatively engaged with one of the legs 30 of the frame. Accordingly a relatively simple, inexpensive and durable connecting mechanism is provided for securing the limb of the doll to its torso while permitting the limb to be moved to a plurality of positions.

The leg mounting mechanism herein described may be entirely assembled exteriorly of the dolls leg thus improving and simplifying the assembly process over other known constructions.

Although an illustrative embodiment of the present invention has been described herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to that precise embodiment, and various changes and modifications may be effected therein by one skilled in the art without departing from the scope and spirit of this invention.
