  • Patent number: 9522449
    Abstract: A method for creating a customized apparatus for holding a door closed comprises comparing a physical door hydraulic piston to two or more diagrammatic configurations to determine which of two or more computer aided design templates to use in fabrication. A straight arm of the physical door hydraulic piston is measured to produce a measurement M1. A user measures from the outside edge of the straight arm to an outside edge of an angled arm of the hydraulic piston to produce a measurement M2. A user measures a width of a pivot point of the hydraulic piston to produce a measurement M3. A user measures the collective height of the straight arm and the angled arm to produce a measurement M4. A user selects one of the templates from the two or more templates based on the comparing step. A CAD operator enters measurements M1, M2, M3 and M4 into the selected template to produce fabrication specifications. Based on the fabrication specifications, a customized apparatus is fabricated for holding a door closed.

  • Patent number: 9095214
    Abstract: A door closure device includes a pivot pin adapted to engage an associated appliance hinge, and a channel rotatably connected to the pivot pin and adapted to be connected to an associated appliance door. A cam is non-rotatably engaged with the pivot pin. The cam comprises a lobed edge including a closing portion. A spring rod is slidably engaged with the channel, and a cam follower is operably engaged with the spring rod. A spring is engaged between the spring rod and the channel and biases the cam follower into engagement with the lobed edge of the cam. The follower moves along the lobed edge of the cam when the channel is rotated relative to the cam and the spring induces a door-closing torque on the channel when the follower is engaged with the closing portion of the cam lobed edge.

  • Patent number: 9009918
    Abstract: A carriage, which serves for holding and shifting a separating element in a running direction along a rail, includes a carriage body that holds at least one running element and a mounting body that is slidably connected to the carriage body and is connectable to the separating element. A coupling member includes a first and second coupling element connected via a bridge member, wherein the first coupling element is slidably held in the carriage body and the second is slidably held in the mounting body. The bridge member has a first coupling surface inclined relative to the running direction which supports the carriage body or the mounting body, so that with a movement of the coupling member the carriage and mounting bodies are shifted relative to one another. The shifting device includes two inventive carriages that are guided in a rail and that are connected to a separating element.

  • Patent number: 8931138
    Abstract: A movement assist device includes a retraction tool having a case, a latch switched between a standby position which is locked inside the case and a retraction position which releases the locking so as to be capable of sliding, and an urging device; and a striker switching the latch from the standby position to the retraction position, or vise versa. The retraction tool or the striker is provided in a fixed body, or a moving body movably disposed in the fixed body. When the latch is switched from the standby position to the retraction position, a sliding door moves by an urging force.

  • Patent number: 8863357
    Abstract: An adjustable door closer has a hollow pedestal with a first and a second chamber as well as an actuating groove. An actuating device is set into the actuating groove. A first piston assembly is set into the first chamber and a second piston assembly set into the second chamber. A partition wall is formed between the first and second chambers. Due to a laterally configured flow resistance unit, the holes to be set into the first and second chambers are reduced to three, including a connecting hole and first and second backflow bypass holes, all of which are connected only to the second chamber from the partition wall. As such, the flow path structure is simplified compared to the five holes required for typical structures. The adjustable door closer could reduce significantly the manufacturing cost and realize better regulating functions with improved applicability and economic benefits.
