摘要:
A cordless, balanced venetian blind or shade with a constant, or a variable force spring motor includes conventional window covering components without the outside hanging lifting cords or cord locking mechanisms. One or more spring motors are employed. A cord spool, in the preferred embodiment, is coupled to one of the spring drums to serve to wind the cords to cause the blind to be raised or lowered, simply by manipulation of the bottom bar of the blind system. Due to the spring forces, the system compensates for the increasing weight on the cords as the window covering is raised and for the decreasing weight as it is lowered.

摘要:
Disclosed is a spring motor and control for use especially with window blinds. The motor comprises a storage drum having a first axis, an output drum mounted for rotation about a second axis parallel to and spaced from the first axis. A spring member is connected to and between the storage drum and the output drum to form a spring motor. The spring motor has laterally extending, spaced apart drum supports on opposite sides of the drums to support them for rotation. A coupled drive is connected to the storage and output drum whereby rotation of one of the drums in a first direction about its axis effects rotation of the other of the drums about its axis and in an opposite direction to cause winding and unwinding of the spring member between the drums. A drive actuator is connected to the coupled drive to effect rotation of the drums, and an adjustable friction member is engageable with one of the coupled drive and the drive actuator to adjustably alter the force necessary to effect movement of the coupled drive.
摘要:
A method for forming a plurality of distinct paint applicators having a common exterior head configuration and distinct paint applying medium configurations includes forming a plurality of handles and forming a plurality of paint carrying units. Each handle formed includes a head having an exterior configuration and an interior having a mouth and head thickness between the exterior configuration and the mouth. Each paint carrying unit includes at least one paint applying medium coupled to a mounting portion that is disposed within an interior of one of the plurality of handles. The mounting portion has a mounting portion exterior configuration and a mounting portion thickness between the mounting portion exterior configuration and the paint applying medium. To form the plurality of distinct paint applicators, the configuration of the paint applying medium is varied while at least one of the head thickness and the mounting portion thickness is also varied.

Roller covers (10) and methods for manufacturing such roller covers are disclosed. According to one method, a paint carrying medium (12) is secured to a core material (14) to form a composite material (16) having at least one core layer (14) and a paint-carrying layer (12), wherein the composite material has opposite edges (24). The opposite edges (24) are positioned adjacent to one another and are secured together. According to an alternative method, a paint-carrying medium (12) having a backing (13) is provided. The backing is treated to an adhering state and is applied to a core (14) while the backing is in the adhering state. According to yet another method, a paint-carrying medium (12) having a backing (13) including opposite edges (14) is provided. The opposite edges (24) are positioned adjacent to one another and are secured to one another. According to an alternative embodiment, a roller cover (110) includes a paint-carrying medium (113) and a core (112) supporting the paint-carrying medium (113). The core (112) includes a plurality of layers (118,120) wherein at least two of the plurality of layers have different characteristics.

A laminated louver (10) is disclosed comprised of a cover (31), adhesive (32) and main body (12). The louver (110) is first extruded (112) with flanges (16) and passed through pressure rollers (117) along with the covering material (31) wherein the flanges (16) capture the covering material (31).
摘要:
An economically improved self-igniting torch tip (10) which provides for variable flame sizes through the selection and attachment of interchangeable burn tips (11) and venturis (22). The torch tip (10) also includes a conveniently located and durable built-in self-ignition system (21-24) which is mounted in a heat resistant housing on the outside of the torch tip.
摘要:
A paint roller is obtained by continuously forming a tubular plastic core, preferably by laying up a two ply wrap over a mandrel (11) with surface heating only of the contacting ply surfaces to form a continuous, endless, unitary thermoplastic core structure, cooling the inside and outside surface of the core structure to a final or near final internal diameter dimension, and, following contracting of the internal core structure to a final desired diameter, heat bonding a compatible thermoplastic pile fabric to the external surface of the core structure, followed by separation of the continuously produced composite structure into final pieces suitable, if desired, for use or further processing.
