A model airplane of the glider or sailplane type made of foamed plastics, comprising rigid stabilizing surfaces and wings and having the bottom side of the fuselage provided with a catapulting hook disposed in the vicinity of the center of gravity in a vertical plane extending through the longitudinal axis of the fuselage, and a sweptback wing profile with a large sweepback and decreasing in thickness and depth from the wing root at the fuselage to the tips of the wing, the connecting lines betw...

An anatomical model for the testing or demonstration of an intravascular device such as guidewires and dilatation catheters for angioplasty procedures. The model has a plurality of interconnecting passageways simulating the abdominal aorta and a renal artery as well as the left and right iliac and femoral arteries with one or more entry ports therein for the introduction and advancement of intravascular devices into the interconnected passageways.

A model skeleton comprises a plurality of interconnected members, hinge joints joining some at least of the adjacent members for relative articulation between those members and a skeletal torso such as to effect partial simulation of animal movements. Each hinge joint has a pair of projections projecting from one member engaging wall of an adjacent member for relative rotation, a barb on the projection retaining that engagement, and sealing surfaces surrounding the projection and effecting seal ...

Anatomical models which represent the female abdominal area and include components simulating the layers of tissue in the abdominal area, the female reproductive organs, and the bladder. A simulated baby, umbilical cord, and placenta are also preferably included; and the tissue layer-representing components are provided with closures so that the dissecting and subsequent repairs of the tissue layers in surgical procedures can be simulated. The models are used to train professionals involved in s...

A toy vehicle including a base frame having a front end and a rear end, with a front fork unit coupled to the front end of the base frame. The front wheel mounted on the front fork is reinforced by solid spoke wheel halves coupled together and a front fender is also coupled to the front fork unit. The front fork unit includes two symmetrical sleeves on each side, one slidable within the other. The outer sleeve has a longitudinal opening and an upper stop surface. The inner sleeve has a correspon...

A fuselage structure for use on a model helicopter includes a longitudinally extending keel defined by a vertical flat plate oriented to lie in parallel relation to a longitudinal axis of the model helicopter. A radio control system component is mounted to the vertical flat plate. The fuselage structure also includes a laterally extending floor perpendicular to the keel, a front bulkhead appended to the keel and a forward end of the floor, and a firewall appended to the keel and a rearward end o...

A surgical model in the form of a knee structure comprises a penetrable outer skin 35, an impermeable penetrable capsule 13 within the model, and penetrable packing material 37 around the capsule. The capsule 13 conforms internally to the general anatomy of the internal cavity of the knee and contains simulated joint components comprising femoral condyles 15 with a femoral notch 16 therebetween, medial and lateral menisci 25 and 27, anterior and posterior cruciate ligaments 29 and 31 and tibial ...

A display device such as a model of a blimp has an aperture formed on one side thereof for display of information carried on a screen within the blimp. Means are provided to rotate the screen and to illuminate the screen interior so as to sequentially display the information through the aperture.

The present invention relates to a model house (10) having a transparent roof (12) and plurality of columns each securely mounted to a base (20). At least three first floor left-right beams (14LRA) which support at least four first floor back-front beams (14BFA). A flooring (24) is securely fastened onto the at least four first floor back-front beams (14BFA). At least two back-front lower beams securely fastened to at least two roof left-right lower beams. A roof left-right center beam (16LRC) i...

A modular building model is provided. The modular building model includes a base and a lower level module disposed on and engaged with the base. An upper level module is disposed on and engaged with the lower level module. The base includes a releasable securing mechanism that secured the upper level module to the lower level module. The releasable securing mechanism permits easy assembly and disassembly of the model for travelling and storage purposes, and variation of mold buildings.
