Description:
BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a doll, and more particularly to driven articulated dolls.

2. Brief Description of the Prior Art

The art is replete with dolls which simulate different moving functions. There are, for example, dolls that simulate walking, crawling, dancing, kicking, swimming and the like. Such dolls which go through the simulated human movements are fascinating to their possessors. Children readily identify with such movable dolls and may easily fantasize with respect to the functions or movements being carried out by the doll.

Some such movable dolls are driven by a wind-up spring motor, others by a battery driven motor. Still others are operated by a pull string mechanism wherein a string is pulled to create stress in a return spring so that, as the return spring slowly rewinds, it drives an output shaft which may be connected to components of the doll. Examples of prior art dolls which are animated, or go throuogh articulated movements responsive to the driving of a pull string motor are found in the Amici U.S. Pat. No. 3,613,299 and the Nutting U.S Pat. 3,603,029.

It is the object of this invention to meet the continuing need and desire in the art to provide an improved form of articulated doll which is operated by a pull string type of rewind motor.

SUMMARY OF THE INVENTION

This invention is directed, in brief, to the provision of a dool having a torso with limbs movably associated with the exterior of the torso and driven by an internal motor operated on a pull string principle.

The best mode currently contemplated for carrying out the invention includes the provision of a doll having a torso or body portion within which a pull string motor is mounted. A pair of legs are pivotally secured to the exterior of the torso and are driven by an output shaft off the pull string motor. In addition, a pair of arms are pivotally connected to the exterior of the torso and are interconnected with the legs so as to be moved responsive to movement of the legs. Furthermore, the head is rotatably mounted on the torso and includes a linkage arrangement with respect to one of the arms so that the head is pivoted as the arm is rotated. The legs themselves are articulated in independent sections which move relative to each other to change the orientation of lower leg components.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT

The doll 10 of this invention includes a medial portion defining a torso 12 having a hollow interior 12a. A head 14 is movably mounted relative to the torso 12 as will be explained. The doll is normally oriented with a front and back and normally forwardly facing features such as the front face of the doll. A pair of arms 16 and 18, terminating in hands 16a and 18a, respectively, and a pair of legs 20 and 22, are movably mounted relative to the torso 12. If desired, the doll 10 may be utilized with an auxilliary implement such as the rocking chair 24.

The torso 12 includes opposed generally parallel side walls 26 and 28 and an upper shoulder cross piece 30. In addition, an outer sheet-like covering 32 spans the side walls 26 and 28 and wraps therearound as well as the shoulder cross piece 30. The doll may be provided with decorative clothing 34 as shown in FIG. 1.

Means are provided in the interior of the torso 12 for driving components of the doll. In the preferred embodiment, this takes the form of a pull string motor continuously operable 40. The motor 40 is located within the interior 12a of the torso which affords interior walls for enclosing the components of the motor. Apertures 50 and 52, formed on a common axis, are provided in the torso walls 26 and 28 and, in addition, an aperture 54 is also provided in wall 26 with these apertures serving to support shafts as will be identified. The motor 40 includes a spool 56 having a bore 58, including enlarged portion 58a and reduced portion 58b. The spool further includes a radial enlargement or flange 60 and another closely spaced apart flange 62. Spool 56 is slotted at 66 manually operable actuating means in the form of and a pull string 68 which terminates in a ring 70, is wound about the spool in the area between the flanges 60 and 62. String 68 extends outwardly of torso 12 through opening 73.

A torsion spring 72 is wound about the shaft 74 having an enlarged portion 76 to which the torsion spring 72 is connected. Enlarged portion 76 of shaft 74 is positioned within enlarged bore 58a of spool 56. One end 75 of spring 72 is positioned in slot 75a of spool 56 so that spring 72 may function as a one way clutch. Shaft 74 is rotatably mounted in apertures 50 and 52 and supports a drive gear 78 and another drive gear 80 is also mounted on the shaft 74 with a pinion 82 interposed between the drive gears 78 and 80. Gears 78 and 80 are in meshing engagement with pinions 84 and 86 positioned on either side of gear 88 mounted on vertically spaced shaft 90. Shaft 90 has one end which extends through aperture 54 in the torso wall 26. The other end of shaft 90 is connected to a spool 92 having a disc or flange portion 92a and a hub portion 92b. A hollow sleeve 96 is positioned about hub portions 92 and serves as a bushing for negator spring 98.

Negator spring 98 includes a leader or tab portion 100 which is positioned within slot 66. Also mounted on hub portion 92b of shaft 90 is a spool 104 including a flange portion 106, which generally abuts flange 60 on spool 56, and a hollow sleeve portion 108 which is coaxially mounted over hub 92.

The pinion 84 has a hub extension 84a which is fixed to a governor 109 having a pair of arms 109a which may expand and retract relative to the generally cylindrical recess 110 in the torso enclosure. Thus, as the motor shafts are driven and the gears thereof rotated, the arms 109a of governor 109 wlll tend to expand outwardly, responsive to centrifugal force, and in so doing, will rub against the interior of the recess 110, thereby retarding the action of the motor gear train.

An arm crank 112 having a bore 112a and a downwardly opening socket 112b is rotatably mounted about a shoulder hub 114 of cross piece 30 with the aid of the interposed bushing 116. A suitable fastener, such as the screw 118, holds the arm crank, as well as an arm 16 or 18, assembled to the remainder of the torso for movement together in unison with crank 112. One crank 112 also has an extension 120 which extends inwardly along the top of the torso 12 and terminates in a forked end 122.

The top of torso cross piece 30 supports an upstanding neck 124 having a reduced end 126. End 126 has a collar 128 connected thereto with the air of fastener 130. Collar 128 has a ball end 128a received in a socket 132 which is fixed in neck opening 132a of the head 14. In addition, the collar 128 includes a series of depending teeth 134, which are of a size and shape to be received in and embraced by, the forked end 122 of extension 120. Thus, as extension 120 moves to-and-fro in an arcuate path about a horizontal axis generally defined by the hub 114, this will cause rotational movement of head 14 about a vertical or upright axis by reason of the engagement between the forked end 122 and the depending teeth 134 of the head collar 128. The ball 128a and socket 132 connection of head 14 permits the head to be positioned at different angles of inclination.

Each leg 20 and 22 is provided with three movable bar-like sections 140, 142 and 144. Section 140 facially abuts flat side walls 26 and 28 and is pivoted on stubs or pins 146, which extend outwardly from each side of the torso. Section 140 is rotatably connected to intermediate section 142 by a suitable fastener or rivet 148. In turn, intermediate section 142 is rotatably connected to bottom section 144, also by a suitable fastener or rivet 150. In addition, intermediate section 142 has an inwardly directed pin 152 and bottom section 144 terminates in an upper camlike surface having a shoulder 156 which abuts pin 152.

Each section 140 of each leg 20 and 22 is provided with an elongate opening 160. Discs 162 are eccentrically mounted at each end of the shaft 74 and are rotatably driven thereby together in unison, thus moving both legs in unison to-and-fro in a front-to-rear direction. It is intended that the discs 162 would have a diameter generally equal to the distance between the sides of the elongate opening or slot 160. In addition, each disc 162 is provided with an annular groove 164 which receives a clamp ring 166 which overlies the sides of elongate opening 160.

The upper portion 140 of each leg is provided an upward extension 168 terminating in a ball or disc end 170, of a size and shape to be received in the depending socket opening 112b of each arm crank 112.

In operation, the pull string 68 may be extended by grasping on the ring 70 and pulling outwardly relative to the housing, which will cause the negator spring to be unwound or placed in a stressed condition. As soon as the string is released the spring will begin to exert its forces in attempting to rewind and thereby drive the gears of the system and the output shaft 74 which bears the discs 162. As the discs 162 rotate about their eccentric mounting with respect to the shaft 76, the upper portion 140 of each leg will pivot about its mounting 146 in a to-and-fro direction. This movement will also cause a to-and-fro swinging movement of the arms 16, in unison in a front-to-rear direction by virtue of the connection between the ball ends 170 and socket ends 112b of arm cranks 112. In addition, the head 14 will be rotated to-and-fro by reason of the connection of the arm crank extension 120 with the head collar 128. The connection of the three leg sections 140, 142, and 144 together is such that the legs 20 and 22 will move as a unit, but that the orientation of the sections relative to each other may be changed. Thus, as shown in FIG. 1, the legs may be oriented with sections 142 and 144 transverse to sections 140, so as to place the doll in a sitting position. If desired, section 144 could be bent downwardly. In the orientation, and with the doll in such an accessory as the rocking chair 24, when the motor is activited, the legs and arms will be will be driven to-and-fro, imparting a rocking motion to the rocking chair. Since the doll's legs and/or arms are positionable in abutment with portions of the rocking chair (e.g., the leg portions 142 in abutment with the seat portion of the rocking chair), the torso will move relative thereto shifting the center of gravity of the entire assembly in a to and fro manner to effect the rocking motion. It is contemplated that other accessories could be provided which would respond to the to-and-fro motion of the arm and legs.

The bar-like configuration of the leg portions 140 bear against the parallel side walls 26 and 28 of the torso 12 and are held in a vertical plane by the clamping action exerted by the annular ring 166 so that rotation of the eccentrically mounted discs 162 in the elongate slot 160 will result in to-and-fro movement of the leg portions 140 relative to generally horizontal axis. The same movement will be imparted to the arms except that as the leg portions 140 are swung forwardly, the arms 16 and 18 will be swung rearwardly. This movement is resultant from the rotation of a single shaft 74 responsive to the driving forces imposed thereon through a gear train which is part of a pull string motor. The torso 12 which houses the motor can be a basic unit to which different driven limbs or accessories may be connected and driven off the shaft 74 and the eccentrically mounted discs 162.

The doll of this revision is particularly suited for use as a so called "miniature" or small doll. The structural arrangement of the articulated arms or legs and the driving mechanism therefor is of such basic simplicity so as to facilitate reduction in size of the components. It is envisioned that the basic doll housing and limbs could be enveloped within different outer garment arrangements so as to simulate persons of different nationalities or characteristics.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, as some modifications may be obvious to those skilled in the art.
