Doll with movable body parts

The invention relates generally to toys and, more particularly, relates to legs having movable body parts.

The invention provides a doll with movable body parts before, which are at least partially formed by a corrugated tube made of plastic, which ait a number of exactly delimited, annular hinge points is provided which form a plurality of annular folds, each such Palte has sides of unequal length, each of which is connected to one of the hinge points in such a way that the shorter one The side part can be pushed into the longer side part.

An embodiment of the invention will be given below of the accompanying drawings. Show it

This articulated arrangement also allows the corrugated tube to bend its longitudinal axis. When the corrugated tube is primed, do the individual folds nest in the (see Fig. 3) and remain in this mutual position _? until a force is exerted to pull the folds apart from this nested arrangement. As a result, the pleated body parts maintain any desired length between the fully compressed and fully extended states. Similarly, the corrugated tube retains when it is within the limits imposed by the angular relationship between the long sides a and the short sides b of the

Wrinkles are given, this bend is bent into a leg until forces are exerted, including this position of the folded hose too

So you can see the Paltensohlatioh, the Ame, legs and neck the pupa forms "bend as you like" around the pupa in a το η to bring numerous possible positions. Attlerdes can suck out or gueaamenge the pleated body parts * » be pushed to the length of the & lieä * aüen and the position of the head to change. These parts remain in the chosen one Length until they experience a change through further manipulation of the patient's tube. How special from the fig * 2-5 you can see the corrugated tube with end pieces, provided, which can be easily inserted into the openings in the body of the tip and head and duroh rubbing there get stuck. In this way, the corrugated tube is releasably connected to the other parts of the body. You can do both But also attach parts to one another with an adhesive · The hands 22 and the feet 24 each have a conical part 26 provided, which has a narrower neck 28, so that hands and feet are easily in the end of the corrugated tube get stuck

In Figures 6-10 is a method of forming the pleated tube illustrated in plastic. For the production of the FaI-tenschlauehes a thermoplastic tube 30 of the desired length is pushed onto a metal mandrel 32, along its length annular grooves are formed in the circumferential direction __ The largest outside diameter d (FIG. 6) of these grooves is preferred slightly smaller than the inner diameter of the cylindrical tube 30 so that the tube will slide over the mandrel can · The plastic tube 30 has a relatively thin Wall and consists of a sufficiently elastic material to bend and deform during the formation of the folds.

Satisfactory results in this regard have been obtained on a polypropylene tube with a wall thickness of 0.2 mm and an inner diameter of 6.4 mm (0.250 inches). In this case the mandrel was with a series of double-beveled, equal annular shapes Parts provided and each such part had an axial length ^W 1 ^H of 2.54 mm (0.100 inches) and a skew of 20 ° to the longitudinal axis on the longer piece of the ring, and an angle of the end face of 5 ° to the transverse axis, as shown in FIG Pig 6 the _

both on the grooved and on the smooth cylindrical part of the dome 6.1 mm (0.240 in). The mold block 34 was provided with transverse grooves that were complementary in length, depth and angle to the inclined ring part on the mandrel. Each such cross-mark on the mold block also had a length of 2.54 mm. and the larger area 36 of the grooves was under 20 inclined relative to the plane of the block, while the smaller surface 38 forms an angle with a plane perpendicular to the block of 5 ° formed

For shaping the corrugated hose the glattzylindriseh · polypropylene tube was slid onto the mandrel 32 30 and preheated in a Jj oven for 15 to 20 minutes, heated at about 115 ° 0 (24O ⁰ F) · The heated mandrel with the deferred Rohr was then as the Formblook 34 placed so that the annular, beveled portions of the dome 32 matched the corresponding grooves of the form block. Then the tube 30 supported by the mandrel was rolled back and forth on the block under manual pressure until it was so deforated that it was snuggled into the sloping surfaces of the dome, as shown in Fig. 8. The mandrel 32 was then axially aligned with a planar cylindrical mandrel 40 (FIG. 9), the outer diameter of which was equal to the largest diameter of the corrugated mandrel 32 (see FIG. 9), and a collar 42 at the upper end of the corrugated mandrel 32 pushed down and

109832/0158

pressed the formed folded tube together and pushed it onto the smooth mandrel 40 (see Pig. 10). The collar 42 is provided with a grub screw 44 so that the corrugated tube can be held in the collapsed state by tightening the grub screw A cylindrical cup 46 was attached to the end of the smooth mandrel 40 in order to hold the collapsed corrugated tube on the smooth mandrel for further processing. A metal block 48 with a cylindrical indentation 50 served to hold the cup 46 and the mandrel 40 in place during the transfer of the corrugated tube onto the born 40 Exposed to 115 ^° C. After this heat treatment, the mandrel and the corrugated tube 30 were taken out of the oven and cooled to room temperature. Then the collapsed corrugated tube was peeled off the mandrel 40 and was ready for use for the toy 10 or the like.

The preheating of the smooth plastic pipe 30 at the beginning of the Process conditions the polypropylene to be deformed into a shape conforming to the grooves of the mandrel 32. The heating of the collapsed or compressed case after the folds have been formed, the polypropylene solidifies along the two joint points χ and y (Fig. 8), which were created during the folding. Of the The resulting corrugated tube is thus provided with two annular joint parts χ and y, which are in a known manner behave like a "living joint", with the molecular structure of the plastic along the hinge lines at each Longitudinal movement of the sole parts on both sides of the joint line increases in strength «The treatment described eliminated Furthermore, any promotion or return property of the poly-
