Abstract
A closure restraint system for providing security of an enclosed space by denying access into the interior of enclosed space or vice versa denying access to the exterior of the enclosed space. Access to said enclosed space is provided by some type of closure, typically a door, gate or access panel. The closure restraint system is mounted as and operates as a single unit with the second support plate being swiveled along the frictionally-restrained axis of the swivel shaft to the locked position with the closure closed. As the closure is attempted to be opened it is held ajar in the locked position; a line of sight or access cannot be obtained into or out of the enclosure; therefore, it does not allow the restraint system to be defeated.
Claims9
A closure restraint system comprising:
- a first support plate secured mesially to a closure jamb near a closure edge, said first support plate including a plurality of swivel knuckle portions providing a cutout between said swivel knuckle portions;
- a second support plate including a plurality of swivel knuckle portions staggered in relation to those of said first support plate swivelly connected to said first support plate by a swivel shaft extending between the swivel knuckle portions of said first support plate and those of said second support plate;
- a second flange portion extending from said second support plate, wherein said second flange portion defines a locked position as it is swiveled in direct contact with a first flange portion of the first support plate;
- whereby said second support plate swivels to the locked position, restraining a closure in a substantially closed position.
A closure restraint system comprising:
- first and second support plates;
- and a swivel shaft;
- the first support plate having,
- an essentially planar mounting portion,
- an essentially planar first flange portion being offset from the mounting portion by a shoulder portion,
- first and second knuckle portions, each being adjacent the first flange portion and distal from the mounting portion;
- the second support plate having,
- an essentially planar second flange portion being substantially the same size as the first flange portion,
- third, fourth, and fifth knuckle portions, each being adjacent the second flange portion,
- a third flange portion adjacent the second flange portion, the second and third flange portions essentially having a cross-sectional L shape;
- each of the first, second, third, fourth, and fifth knuckle portions being curled around a portion of the swivel shaft wherein the swivel shaft is semi-restrained by friction but can still rotate relative to the first and second support plates and further whereby the second support plate can move pivotally with respect to the first support plate;
- the second flange portion being in direct contact with the first flange portion and the shoulder portion when the system is in a locked position.
