016400000 | COUNTERBALANCE DEVICE, PER SE | 10 |
20100263167 | Counter-balance apparatus and method for providing a stabilizing force - A counter-balance apparatus and method, including configurable weights, suspensions, and supports, upon which an external force can be exerted, and as a result, will react as a counter-balance to said external force as a means to provide force resistance and stability; wherein the construct may be encapsulated, varied in materials, size, and substance, enabling said counter-balance with a predictable and known effect to be produced at scale, readily installed, moved, or manipulated, to address a plethora of stabilization applications, and which further comprises fastener(s) and/or band(s) to secure it to immobile, mobile, or in-motion objects, and computational and communications capabilities to dynamically adjust to external factors. | 10-21-2010 |
20130061428 | COUNTERWEIGHT DEVICES AND SYSTEMS FOR PAINTBRUSHES AND OTHER HAND TOOLS - Counterweight devices and systems for a hand tool, such as a paintbrush, having a forward working end and a handle extending rearwardly along a longitudinal axis, having a distal end, with the hand tool having a center of gravity located on the axis forward of the midpoint between the working and distal ends, are disclosed. A counterweight device includes a counterweight body configured to be mounted to a portion of the handle, and one or more counterweights supported on the counterweight body. The counterweight device is thereby adapted to shift the center of gravity of the hand tool rearward along the axis of the handle to a predetermined extent when the counterweight body is mounted to the handle. A counterweight system includes a set of interchangeable counter counterweights each having a different weight and each configured to be removably attached either to the counterweight body or to a counterweight attached thereto. | 03-14-2013 |
20140157547 | GRAVITY-BALANCING DEVICE FOR ELECTRIC ROLLER SHADE LIFTING SYSTEM - A gravity-balancing device mounted to a head roller of an electric roller shade includes a mounting bracket, a spiral elastic element mounted to the mounting bracket, and a winding element rotatably mounted to the mounting bracket to locate adjacent to the spiral elastic element and connect to the head roller. The spiral elastic element has a fixing end connected to the mounting bracket and a connecting end connected to the winding element. When the head roller is driven by a motor of the electric roller shade to rotate and lower a shade fabric of the roller shade, the gravity-balancing device synchronously generates an upward winding force to the head roller to offset a gravitational force lowering the shade fabric, so that the motor can drive the head roller to rotate reversely and lift the shade fabric with reduced motor torque output to save power and extend the motor life. | 06-12-2014 |
20150113767 | WEIGHT ASSEMBLY FOR A FAUCET - A weight assembly for a faucet contains: a counterweight including a channel, the channel having an elongated first opening and a longitudinal height, and the longitudinal height being larger than a diameter of the hose; the counterweight also including a non-circular orifice, a first accommodating cavity, and a second accommodating cavity; a retainer inserted into the second accommodating cavity, the non-circular orifice, and the first accommodating cavity and including a notch for defining a second opening facing to the first opening; the notch having an arc-shaped contacting fringe; a longitudinal height of the second opening along the Z-axis direction being larger than the diameter of the hose; a pressing member mounted on a top end of the retainer; a resilient element defined between the first accommodating cavity of the counterweight and the pressing member. Thereby, the counterweight is removed and replaced easily by pressing and releasing the pressing member. | 04-30-2015 |
20160069117 | CLOSURE PANEL COUNTERBALANCE MECHANISM WITH FRICTION DEVICE - A friction based counterbalance mechanism for coupling with a closure panel to assist in opening and closing of the closure panel for at least a portion of a path between a fully closed position and a fully open position of the closure panel, the counterbalance mechanism including: an elongate member positioned on a longitudinal axis extending between the proximal and distal ends of the counterbalance mechanism, the elongate member having a peripheral surface, the elongate member having a proximal end for coupling to one of the closure panel and a body of a vehicle; a travel member having a body and at least one friction member mounted on the body, the travel member positioned on the longitudinal axis for reciprocation there along and for providing contact between the at least one friction member and the peripheral surface, said contact for generating a friction force in a first region along the longitudinal axis and in a second region along the longitudinal axis; and a support member coupled to the travel element at a proximal end and for coupling at a distal end to the other of the closure panel and a body of a vehicle, the support member for guiding said reciprocation. The friction based counterbalance mechanism can be incorporated as part of a biasing strut such as a spring configured strut. | 03-10-2016 |
20160167183 | Counterweight Mechanism for Swivel Arrangement | 06-16-2016 |
20160376753 | Cold Planer Having Improved Mill Cutting Efficiency - A cold planer is disclosed. The cold planer may include a frame having a first end and a second end. Further, a counterweight may be placed between the first end and a second end, and this counterweight may be movable between a current position and a second position along a longitudinal axis of the cold planer. Furthermore, the cold planer may include a counterweight position sensor operatively connected to the counterweight and be configured to determine a current position of the counterweight and generate a counterweight position signal. | 12-29-2016 |
