1. Field of the Invention The invention pertains generally to the field of sewing machine toys and more particularly to a simulated sewing machine toy of small size permitting a child-user to energize the toy in a play environment including a doll to simulate use of the sewing machine by the doll.
2. Description of the Prior Art US. Pat. No. 2,878,614 is one example of a prior art toy simulated sewing machine.
OBJECTS AND SUMMARY OF THE INVENTION A primary object of the present invention is to provide a new and useful simulated sewing machine toy exemplifying improvements over prior art sewing machine toys.
Another object of the present invention is to provide a simulated sewing machine toy of small size and of such an arrangement that a child-user may simulate use of the sewing machine toy by a doll.
According to the present invention, a simulated sewing machine toy includes a plastic housing which may be molded into two halves with each half including one half of the base plate, sewing machine head and post. A horizontal shaft includes a crank on one end and a driving disc on the other end and is rotatably mounted in the housing. An electric motor is mounted in the housing and includes a vertical output shaft which carries a friction drive engaging one face of the disc on the horizontal shaft for imparting rotation thereto. The crank on the horizontal shaft rides in a transverse slot which is provided in a simulated, flat plastic needle having a blunt tip.
The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of use, together with further objects and advantages thereof, may best be undersood by reference to the following description, taken in connection with the accompanying drawing in which like reference characters refer to like elements in the several views.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of a simulated sewing machine toy constituting a presently preferred embodiment of the invention;
FIG. 2 is an enlarged, cross-sectional view taken along line 22 of FIG. 1;
FIG. 3 is a cross-sectional view taken along line 33 of FIG. 2;
FIG. 4 is an enlarged, partial cross-sectional view taken along line 4-4 of FIG. 2; and
FIG. 5 is a partial, enlarged cross-sectional view taken along line 5--5 of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring again to the drawing, a simulated sewing machine toy constituting a presently preferred embodiment of the invention, generally designated includes a two-piece housing 12 having a front half 14 and a rear half 16 each molded in one piece from a suitable plastic material, such as a styrene monomer or an acetal resin.
The housing half 16 is shown in FIG. 2 and includes an integral base plate 18, post 20 and a simulated sewing machine head 22.
Shaft 52 includes a first end 58 which carries a crank 60 working in a transverse slot 62 provided in a cross bar portion 64 on a simulated, flat plastic needle 66 having a blunt tip 68 and being reciprocally mounted, as indicated by arrow 70 (FIG. 3) in an upper slot 72 and a lower slot 74 provided in head 22. Shaft 52 also includes a second end 76 which carries a wheel 78,
which is mounted outside housing 12 for simulating a conventional sewing machine wheel, and a first disc 80, which is mounted inside housing 12 adjacent wall 44 and. serves as a thrust bearing, and a second disc 82 having a face 84 drivingly engaged by resilient sleeve 42 on motor output shaft 40. A cruciform-shaped reinforcing member 86 joins discs and 82 together and is formed integrally with shaft 82, crank 60, wheel 78,
and discs 80, 82 during a molding operation where shaft 52 is formed from a suitable plastic material, such as acetal homopolymer.
Joining together of housing halves I4, 16 is facilitated by suitable lap joints, such as those shown at 92 on housing half 16, locating pins 94, which are provided on housing half 14 and which engage suitable apertures 96 provided in housing half 16, and gripper pins 98, which are provided on housing half 14 and which engage apertures 100 provided on housing half 16 Foam rubber pads, such as those shown at 102, 104 for housing half 16, may be provided at each corner at the bottom of housing 12 to minimize creeping of toy 10 when motor 38 is energized by connecting its electrical cord 106 to a suitable low-voltage electrical source such, for example, as the source shown in copending application, Ser. No. 145,682, filed May 21, 1971, and incorporated herein by reference. Electrical cord 106 carries a male plug 108 (FIG. 1) for plugging toy 10 into this low-voltage source.
While this particular simulated sewing machine toy herein shown and described in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of a presently preferred embodiment of the invention and that no limitations are intended to the details of construction or design herein shown and described other than as defined in the appended claims, which form a part of this disclosure.
