Utility model registration "jumping jack"

The innovation relates to a jumping jack to be hung up with a pull-through on a string against the action of a restoring force movable limbs.

In the usual execution of the jumping jack there are torsos and head cut out in front view and by pulling on the cord, the arms and Legs spread apart, which then fall back into their hanging position due to their own weight. This kind Jumping jacks derive their game effect only from the movement of the limbs, but it becomes through the movement itself no meaningful act expressed.

It is the task of the present innovation to create a jumping jack of the type mentioned, which is used to promote the purpose of the game and the satisfaction of something immanent in man The instinct to play is not just due to the in itself not very meaningful mobility of some parts to pull on the string tempted, but also through imitation, an expressive movement in the giving person an additional one Exerts a stimulus to operate the movement mechanism.

The above object is achieved according to the innovation by a jumping jack, in which the tongue and at least

71220S7u.li. 71

an arm connected to lowerable pants can be moved.

In a preferred embodiment of the innovation, the movement of the tongue (and arm also at least a known 'way from articulated verbuiidenein Existing thigh and lower leg, articulated to the trunk, can be angled.

Various design options are conceivable for the movement mechanism of the tongue and the trousers. Practically preference is given to one in which the trousers are attached to a hanger that takes the position of a belt, which is around a fulcrum located in the region of the belly of a trunk cut in profile or half-profile can be swiveled so far that the rear part of the jumping jack is exposed in the swiveled down position *

The movement mechanism of the Zu:. ^ E can thereby be simplified be that this is not stretched out straight out, but by one from the back up to the front down diagonally cut mouth slit can be pushed forward diagonally downwards is.

In order to bend the knee joint, it is proposed in a further preferred embodiment of the innovation, that a lower section of cord connected to the bracket between the bracket and a freely hanging one

The end of the handle is passed through an eyelet on the thigh, wherein a torque can be exerted on the thigh through the cord, which is stretched in the vertical direction during the pull, via the eyelet is. The buckling in the knee joint can be increased by the fact that the lower section of the cord also through an eyelet is guided on the lower leg or foot.

A spring is preferably used to apply the restoring force, which is expediently made of

712209711.11.71

elastic plastic strips existing tongue by pulling pulls back up into the mouth slit and also pulls the hanger with the trousers in via an upper section of cord strives to keep its upper position.

The innovation is explained below with reference to an embodiment shown in the drawing.

The jumping jack pictured is drawn in front and side views. Its body is made up of five relatively movable, flat wooden, metal or plastic parts, namely a body and head part 1o, an upper arm 12, a forearm 14, a thigh 16 and a lower leg with a foot 18. The following exist Joint connections: a shoulder joint 2o, an elbow joint 22, a hip joint 24 and a knee joint 26. The Jumping jack has a train 28, which is made as a flexible plastic strip formed and inserted from behind through a mouth slot 3o. The latter is from the back above cut forward and down at an angle, as shown in the side view. The rear end of the tongue 28 is on a rigid slide provided with a longitudinal groove 32 attached. Through the longitudinal groove 32 there is a screwed screw 36 or the like inserted into the head part, which with its head, the diameter of which is greater than the width of the longitudinal groove 32, the slide 3 ^ wäh ^ .ond its vertical movement essentially in flat contact with the rear of the head and torso part 1o.

The fine artisan wears trousers 38, indicated by dashed lines, which is attached to a bracket 4o, which essentially has the position of a belt and a flat one in the form of a belt Rectangular curved, self-contained wire ring consists. This ring is in the area of the jumping jack's stomach inserted through a hole 42 in the body part 1o. This Hole forms a bearing around which the bracket 4o down

The fabric in the area of the bracket is at an articulation point 44 the hand hinged so that the "Junterarr: 14" and also the Oberarn 12 -irbev / egt v; erden, v; hen the hanger 4o with the trousers 38 pivoted into the lower position indicated by 46 will.

The jumping jack is hanging on a cord 48 on which he is medium; an eyelet 5o is attached. There is a tension spring on the same eyelet 52 hooked, which normally the tongue 28 and the slide 34 in their upper, retracted position holds. An upper cord section 54 then extends from the slide 34 to a fastening point 56 on the bracket 4o. A lower cord section 58 is attached at 60 to bracket 4o. The lower, free-hanging end of the string section serves as the end of the handle, which is used to actuate the movement mechanism the jumping jack is pulled.

The lower cord portion 58 is through an eyelet 62 on Thigh 16 and a further eyelet 64 are guided on the lower leg 18 in the area of the foot. Because of the relative location of the eyelet 62 and 64 with respect to the attachment point 60 of the lower cord section 58 on the bracket 4o and in particular the hip joint 24 can be determined by how much the knee joint 26 moves forward when the bracket 4o is pulled down angled. The length of the groove 32 limits the movements of the ones movable by the cord 54, 58 and the spring 52 Parts. When pulling the cord 58, however, there is always each according to the direction of pull, a different position of the thigh and lower leg. Instead of the stop that the slide 3 ^ forms in cooperation with the screw 36, other stops can of course also be used.
