ABSTRACT:
FIELD OF INVENTION
This invention relates to toys and is particularly directed to toys which move in response to heat.
PRIOR ART
Toys which are self-moving are always a source of interest and enjoyment and numerous types of toys have been proposed which provide movement in response to changes in temperature. Some prior art heat-sensitive toys have employed electromechanical properties to produce movement. However, most of these toys are complex devices and, hence, are relatively expensive to produce and purchase. Other prior art heat-sensitive toys have required electrical coils to be built into the toy. However, such coils involve the possibility of electrical shock to the user and, hence, are undesirable. Still other prior art heat-sensitive toys have been formed of metal-paper laminates which are easily torn. A search in the United States Patent Office has revealed the following:

Each of these references is subject to the disadvantages discussed above. Thus, none of the prior art heat-sensitive toys has been entirely satisfactory.
BRIEF SUMMARY AND OBJECTS OF INVENTION
These disadvantages of the prior art are overcome with the present invention and an improved heat-sensitive toy is provided which is simple and inexpensive to produce and purchase, has no mechanical moving parts to break or require maintenance, does not require a built-in electrical coil and yet can be used repeatedly to provide enjoyment over an extended period of time.
The advantages of the present invention are preferably attained by providing an improved heat-sensitive toy comprising at least one heat-responsive moveable strip formed of mylar polyolefin which has been pulled against a straight edge. The mylar polyolefin strip preferably has a portion thereof bonded to a self-supporting member, formed of suitable material, such as paper, plastic, metal or the like.
Accordingly, it is an object of the present invention to provide an improved heat-sensitive toy.
Another object of the present invention is to provide an improved heat-sensitive toy which is simple and inexpensive to produce and purchase.
An additional object of the present invention is to provide an improved heat-sensitive toy which has no mechanical moving parts to break or require maintenance.
A further object of the present invention is to provide an improved heat-sensitive toy which does not require a built-in electrical coil.
Another object of the present invention is to provide an improved heat-sensitive toy which can be used repeatedly to provide enjoyment over an extended period of time.
A specific object of the present invention is to provide an improved heat-sensitive toy comprising at least one heat-responsive moveable strip of mylar polyolefin which has been pulled against a straight edge having a portion thereof bonded to a self-supporting member formed of suitable material, such as metal, plastic, paper or the like.
These and other objects and features of the present invention will be apparent from the following detailed description, taken with reference to the figures of the accompanying drawing.
