  • Patent number: 5689853
    Abstract: A closure member restraining device 10 is provided which comprises a body mountable on a support surface, such as a wall, adjacent the closure member, a buffer arm 14 and a catch 16. The body comprises a buffer housing with a tubular sidewall 20 and an integrally moulded skirt 22 extending backwardly from the housing. The catch 16 depends from the buffer housing and automatically engages a handle formation on an opened door and restrains the door, so preventing it from closing. The buffer arm 14 is movable into and out of the buffer housing by coaxial screw or sliding movement to pre-set its position so that irrespective of the distance between the handle formation and the closure member, the buffer arm 14 abuts the closure member when the handle formation is engaged by the catch, thereby preventing movement of the closure member.

  • Patent number: 5568954
    Abstract: A device for holding a door upright for painting comprises a bracket that attaches the device to the electrical junction box in a ceiling, a telescoping rigid section held by the bracket, and a pin at the end of the rigid section that engages the top edge of the door. The telescoping rigid section adjusts to different door sizes and different ceiling heights. It also moves to a retracted position from an extended position, so that the door can be easily positioned and removed. In the vertical position, only slight force is needed to hold the door there, force provided in part by the attachment of the device to the junction box. Use of the junction box obviates the need for more elaborate support systems.

  • Patent number: 5465460
    Abstract: A doorstop having a housing contains a striker block slideably mounted in the housing. The striker block is biased in a first position where it engages a spring loaded door restraining member holding the door restraining member in a down position. When the striker block is moved into a second position against its biasing force, the striker block disengages the spring loaded door restraining member and the door restraining member is urged into an up position. A force applied to the door restraining member sufficient to overcome the spring and biasing forces, will return the door restraining member to its down position, the biasing force will return the striker block to its first position and engage the door restraining member and hold it in the down position.

  • Patent number: 4639023
    Abstract: The locking bar assembly of the present invention is adapted to lock horizontally slidable, overlapping window doors, such as patio doors, in closed position. One end of a locking bar is pivoted to a bracket, or pivotal member, for movement in between a stored vertical position and a horizontal locking position. A clasping member, carried by the bracket, resiliently retains the locking bar either in the vertical position, or against upward pivoting from its horizontal position. The bracket is so constructed that it can be secured to the sash or to the handle flange of one door when the two doors can be opened, or to the door opening frame when only one door can be opened.

  • Patent number: 4609910
    Abstract: The system automatically warns when opening of an exit door is attempted, causing an alarm to be made and preventing full opening for a predetermined period of time. Such a system includes an electromagnet, timer, alarm and activator switch connected in series with a power source such as house current and disposed in and around the frame with no electrical connection to or from the door. A magnetically attractable plate or prong is secured to the door adjacent to the electromagnet. The switch may include a spring biased plunger on the frame, held in the closed circuit position against the spring bias with the door closed. The switch automatically moves to the closed circuit position when the door begins to open, causing an alarm to be immediately sounded and the plate to continue to be strongly held by the electromagnet, thereby preventing full opening of the door. The system permits the full opening of the exit door only after a suitable period of time has elapsed.
