016193000 | SASH BALANCES | 21 |
20100077563 | Side Load Carrier and Balance System for Window Sashes - A carrier assembly consisting of a carrier, a carrier encasement and a sash latch. The carrier is secured to the end of one or more balances, including spiral rod and block and tackle balances. The weight of the sash is borne by a platform on the carrier. The undesired vertical forces exerted by the balance on the carrier is thereby translated into a force urging the carrier toward the sash until firm contact is made between the carrier encasement and the side of the sash. The translation of the torsional force into a side directed force eliminates or substantially reduces the friction that might otherwise have existed between the carrier and the jamb channel caused by the undesired vertical forces exerted by the balance on the carrier. | 04-01-2010 |
20100287731 | Window Maintenance Apparatus for A Tilt-In Sash - A window maintenance apparatus for a tilt-in sash includes a base leg for extending generally upwards from a floor towards a window. The base leg includes a first foot for resting on the floor. A hinged leg is joined to the base leg proximate an end of the base leg for extending generally downwards towards the floor. The hinged leg includes a second foot for resting on the floor. An extension tube extends upwardly from the base leg where a length of the extension tube above the base leg is adjustable. A locking mechanism locks the extension tube at an adjusted length above the base leg. A first sash support is rotatably joined at a first position on the extension tube for rotating about the extension tube from a first position to a second position for supporting the tilt-in sash in a generally horizontal position. | 11-18-2010 |
20110041287 | SIDE LOAD CARRIER AND BALANCE SYSTEM FOR WINDOW SASHES - The carrier is securable to the end of a window balance, including, but not limited to, spiral rod, extension spring, and block and tackle balances. The weight of the sash is borne by a sash assembly coupling portion of the carrier. The upward force exerted by the balance on the carrier during opening or closing of the sash is translated into a force urging the carrier toward the sash, until contact is made between the carrier assembly and the side of the sash. The translation of the upward force into a side-directed force eliminates or substantially reduces the friction that might otherwise have been created between the carrier and a carrier channel in the jamb. The side-directed force preferably removes the carrier from any contact with a carrier channel, thereby eliminating friction from the carrier rubbing against the carrier channel and even eliminating the need for a carrier channel. | 02-24-2011 |
20120030903 | Side Load Carrier and Balance System for Window Sashes - A carrier assembly can be used to couple a balance assembly with a window sash. The carrier assembly can engage the window sash to transfer a force from the balance assembly to balance a weight of the window sash. The carrier assembly, due to interactions of the window sash with the carrier assembly and the balance assembly with the carrier assembly, can tightly engage the window sash, either directly or through a bracket, to substantially eliminate unselected movement or forces applied from the balance assembly. | 02-09-2012 |
20120151715 | Gate adjustment system - A gate adjustment system has a bull-nose glide, a flat glide, a plurality of spacers, a gap size gauge, and a gap adjustment wedge. The glides are attached to the latch post and the latch side of a gate opposite one another. As the gate is shut, the bull-nose portion of the bull-nose glide impacts the rounded edge of the flat glide. The two curved surfaces allow the impact force to cause the gate to be lifted and pushed back into alignment. The gap adjustment wedge can be positioned between the top of the latch side and the latch post and pushed downwards into the gap until the gap is uniform from the top to the bottom. The gap size gauge then measures the size of the gap and that measurement is used to determine which of the plurality of spacers should be installed with the glides. | 06-21-2012 |
20120227214 | WALL CLIP AND SHIM ADAPTED FOR INSULATING CONCRETE WALLS AND SIMILAR MATERIALS - A stackable shim system. A first shim includes a receiving feature, an attachment feature, and a main portion having a first thickness. A second shim also includes a receiving feature, an attachment feature, and a main portion having a second thickness. The receiving feature of each shim is configured to engage with the attachment feature of the other shim such that either shim can be removably attached to the other to create a stacked shim having a main portion having a thickness that is the sum of the first and second thicknesses. The shims may be conveniently used for taking up space and/or accommodating for irregularities in construction materials. | 09-13-2012 |

016196000 | Sash and cord | 2 |
20090188075 | Shoe Support Terminal Connection for Inverted Balance - In a block and tackle window balance, the balance shoe holds and upwardly biases the terminal connector in a mounted position. A biasing element of the shoe maintains the terminal connector in a pocket of the shoe during operation of the balance. The terminal connector is prevented from laterally exiting the pocket in the mounted position by a widened portion on the terminal connector and a locating surface extending from the shoe toward the pocket. Manually pressing down on the biasing element or the terminal connector itself to lower the terminal connector in the pocket until the widened portion clears the locating surface allows lateral removal of the terminal connector from the pocket. During operation of the balance, however, the terminal connector does not experience a sufficient downward force to overcome the upward bias such that the widened portion never clears the locating surface. | 07-30-2009 |
20110302742 | Block and Tackle Window Balance with Bottom Guide Roller - Disclosed are apparatus for a block and tackle window balance to be incorporated in single and double hung window assemblies.

016197000 | Spring | 11 |
20080235905 | Pre-Tension Anchorage for Spiral Balance - A method and device for applying a pre-tensioned force to a spiral window balance. The spiral balance includes a containment tube, a spiral rod and a torsion spring that traverses the length of the containment tube. The device includes a pre-tensioning insert that is contained within an anchorage fixed within the upper end of the containment tube. At least one boss formed at the base of a bore within the pre-tensioning insert defines a channel that receives the upper end of the spiral rod. To apply a pre-tensioned force to the spiral balance, the lower end of the spiral rod is pulled from the lower end of the containment tube, turned a number of revolutions and reinserted into the containment tube without being allowed to rotate. The upper end of the spiral rod is non-rotatably retained within the channel by the boss to prevent it from losing its pre-tensioned force. | 10-02-2008 |
20090119874 | Snap-On Window Balance Terminal Clip - A snap-on terminal clip for installation onto the end of the spiral rod of a spiral rod window balance. The upper region of the terminal clip lockingly engages a locking pin secured to the external end of the spiral rod. The lower region of the clip terminates in a substantially hook shaped segment that engages the ledge of a window sash, thereby supporting the sash as it moves vertically through the jamb channel of the window assembly. | 05-14-2009 |
20100050379 | Block and Tackle Window Balance with Bottom Guide Roller - Disclosed are apparatus for a block and tackle window balance to be incorporated in single and double hung window assemblies. In one embodiment the block and tackle window balance includes a roller secured within a bottom guide to increase range of travel of a window sash. | 03-04-2010 |
20100083464 | Parallel Axes Compound Balance - An apparatus and method to substantially cancel out the opposing torsional forces of the torsion spring of a spiral rod subassembly and the extension spring of a compound spiral rod balance on the carrier element. The extension spring and the rod spiral balance subassembly are parallel, connected at their lower ends to a carrier element and at their top ends either to an upper mounting cap or separately to the wall of the jamb channel. The spiral rod is turned a pre-determined number of times in a direction opposite from that in which the extension spring is turned so that the torsional forces acting on the carrier element from the torsion spring and the extension spring substantially cancel out each other. The balancing out of the counteracting torsional forces eliminates or substantially reduces the friction between the carrier element and the jamb channel. | 04-08-2010 |
20100101047 | Apparatus and Method for Canceling Opposing Torsional Forces in a Compound Balance - A method and apparatus for reducing the torque of a compound balance in order to substantially cancel out the torsional force of the torsion spring acting on the spiral rod by creating an equal and opposing torsional force on the extension spring. The apparatus is an assembly connector that is non-permanently engaged with the extension spring, with the spiral rod being tensioned by the torsional force of the torsion spring. Alternatively, the extension spring may be turned in a direction to apply more torque than is required for operation of the compound balance. It is then engaged with a non pre-tensioned spiral rod sub-assembly to transfer the excess torque to the torsion spring of the spiral rod sub-assembly. In this manner, the opposing torsional forces of the torsion spring and the extension spring acting on the spiral rod substantially cancel out each other. | 04-29-2010 |
20100212110 | Device and Method for Improving the Installation of Pre-tensioned Spiral Balances in Window Balances - The present device is an extender for pretension spiral rod window balances. The spiral rod extender is attached to the end of the spiral rod by the window or balance manufacturer. At the window manufacturer, the sash is installed into the window frame and the balance is inserted into one of the jamb channels. A hook tool, having a hooking element at one end, is used to grab onto a hole in the end of the spiral rod to pull it a sufficient amount out of the containment tube. The hook tool manipulates the spiral rod so that a sash hook mounted on the balance engages a ledge at the end of the sash, thereby securing the balance to the sash. The spiral rod extender is then removed from the spiral rod and may be reused by the balance manufacturer or discarded as desired. | 08-26-2010 |
