ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a pulp-molded dummy, and more particularly to a pulp-molded dummy that is completely recyclable and would not cause any public hazard and therefore meet international environmental protection requirements.
Most of the conventional dummies are made of fiberglass (FRP). The FRP dummy is welcomed for its light weight, smooth surface and sufficient structural strength. However, FRP dummy is prohibited for use in some advanced European and American countries that deem environmental protection of great importance, because fiberglass is a kind of chemical compound and is hazardous to the environment.
There is a paper-made dummy developed in foreign countries to replace the FRP dummies. Such paper dummy is formed by gluing paper onto a mold sheet by sheet and layer by layer until the glued paper reaches a required thickness. Such paper dummy is completely hand-made and therefore requires a lot of time and labor to complete it. Moreover, a large quantity of solvent-based bonding material is used to glue the paper onto the mold and workers' hands are subject to skin illness due to contact with such bonding material for a prolonged time. And, such solvent-based bonding material will cause environmental pollution, too.
It is therefore tried by the inventor to develop a dummy that fully meets the requirement of environmental protection and may be easily formed to eliminate the drawbacks existing in the conventional FRP and paper dummies.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a pulp-molded dummy that can be easily formed to obtain smooth outer surface and sufficient hardness, and meets the requirement of environmental protection.
To achieve the above and other objects, the pulp-molded dummy of the present invention mainly includes a front half shell and a back half shell both being formed through vacuum-molding of pulp. The vacuum-molded front and back half shells are dried and compressed to obtain high density and smooth outer surface. Several pairs of upper and lower flanges are provided on inner surface of the front and the back half shells at predetermined positions, such that pulp-molded partitions can be horizontally connected to the front and the back half shells to reinforce the same by engaging outer peripheral edges of the paper partitions with the pairs of upper and lower flanges.
Continuous groove and continuous rib may be separately formed along outer peripheral edges of the front and the back half shells, so that the front and the back half shells may be assembled to each other by engaging the groove with the rib to form a complete hollow dummy.
The pulp-molded hollow dummy is internally provided with a paper pipe vertically extended through the horizontal paper partitions. A supporting pipe upward extended from a stand extends through a metal coupler provided at a bottom of the dummy and into the paper pipe. When the dummy is adjusted to a desired height relative to the supporting pipe, the latter may be locked to the metal coupler by tightening a stop screw against the metal coupler.
