US Patent:

D534967, Jan 9, 2007

Filed:

Aug 9, 2005

Appl. No.:

29/235962

Inventors:

Leonard R. Clark - Oreland PA, US

International Classification:

2101

US Classification:

D21562

US Patent:

20040200924, Oct 14, 2004

Filed:

Jan 26, 2004

Appl. No.:

10/763283

Inventors:

Leonard Clark - Oreland PA, US
H. Greene - Boyertown PA, US

International Classification:

B64C027/22

US Classification:

244/00700B

Abstract:

A vertical take off and landing aircraft toy has a fuselage with a plurality of fins and a rotor assembly. The rotor assembly may be driven by an electric motor, powered by a battery, an air motor powered by compressed air, or a gasoline engine, radio controlled in each case to control the speed of the motor. The rotor assembly includes a head portion coupled to the motor output shaft, a central hub coupled to the head portion, and a pair of airfoil blades. The head portion allows pivoting of the central hub about an axis generally aligned with the axis of the blades, while the blades are pivotable with respect to the central hub about an orthogonal axis. The fins on the fuselage resist counterrotation of the fuselage with respect to the rotation of the blades; alternatively, a pair of counterrotating blades may be provided.

Appl. No.:

11/177428

Inventors:

Leonard Clark - Oreland PA, US
H. Greene - Boyertown PA, US

International Classification:

B60K 1/00

US Classification:

180065100

Abstract:

A motorized toy vehicle or Wall Racer that is capable of operating on vertical and inverted horizontal surfaces such as walls and ceilings, while being manufacturable at reasonable cost and operable on batteries having sufficient lifetime as to be enjoyable. One or more battery-powered fans draw air from around all or defined portions of the periphery of the interior volume of the Wall Racer through a carefully-shaped duct, so that the air in the portion of the duct immediately adjacent the surface flows at high velocity and low pressure; the relatively greater pressure of the surrounding air urges the vehicle against the surface, allowing it to adhere to vertical surfaces, such as walls, or operated inverted on horizontal surfaces, such as ceilings.

International Classification:

A63H 2922
A63H 3004
A63H 1736

US Classification:

446458

Abstract:

A spherical vehicle including a spherical shell having a drive shaft secured to the interior wall thereof. A drive motor is connected to the shaft for imparting a rolling motion to the spherical vehicle on a supporting surface. Continuous steering of the vehicle is accomplished by changing the position of a mass suspended from the drive shaft to thereby change the center of gravity of the vehicle.

International Classification:

A47F 514

US Classification:

211182

Abstract:

A storage system in accordance with the preferred embodiment of the invention includes a support member formed with a first leg providing a track surface and a second leg extending at a generally right angle thereto and providing a guide surface. The second leg member is formed with a plurality of connecting means, one at each end of the support member, for securing the support member to adjacent support posts. The connecting means includes a hook member formed on the second leg and a tab member also formed on the second leg and forming an angle greater than 90. degree. with the portion of the second leg located between the hook member and the tab member. To assemble the storage system, the hook members are first engaged with slots in an adjacent pair of posts and the support member is then rotated so that the tab members pass into other slots in the post members. Thereafter, each of the tab members is bent toward the hook member so that it forms an angle less than 90. degree. with the portion of the second leg between the tab member and the hook member and so that it underlies the portion of the associated post between the slots whereby the support member is securely retained on the post members.

Appl. No.:

7/897425

Inventors:

Leonard R. Clark - Oreland PA

International Classification:

A63H 1736

US Classification:

446465

Abstract:

A toy vehicle comprises a chassis having a pair of rear wheels journaled for rotation about a rigid axle and a pair of front wheels mounted for being steered cooperatively. A steering mechanism is controlled by a steering wheel at the end of a steering column connected to the steering mechanism by a universal joint. A child playing with the vehicle can propel the vehicle forward by pushing on the steering wheel, but can only steer it in a desired direction of travel by turning the steering wheel.

International Classification:

A61M 1500

US Classification:

12820023

Abstract:

An aerosol throat spray with a spray-counting mechanism including a lead screw driven in rotation by a rachet in which a follower on the lead screw moves from a starting location indicating the aerosol is "full" to an ending position indicating the aerosol is "empty", wherein the rachet is actuated by a pawl of springy construction material which, after each power stroke, returns to a ready position for the next power stroke in response to the spring urgency of its construction material.
