A device (1) is described for stopping, releasing and restoring the position of roller-type window nets (3, 48), comprising: a fixing shaft (13) having a coupling groove (15) formed in a front external circumferential surface thereof and an insertion groove (16) formed in a rear surface thereof; a ball rotor (18) inserted into the fixing shaft (13) and coupled to the external circumferential surface of the fixing shaft (13), including a front portion coupled by means of a spring (30) and having a conveying groove (20) formed in a surface thereof for conveying a ball (40) and a guide jaw (38) formed in a central part thereof, wherein the ball (40) is inserted into the conveying groove (20); and an outer rotor (42) coupled to the conveying groove (20) via the ball (40) and having a rotation groove (44) formed in an internal circumferential surface thereof, wherein the ball (40) is coupled to the rotation groove (44) to rotate.

Embodiments for barrier assemblies and setup configuration of these barrier assemblies are disclosed. The barriers are used to block the entry of children or animal into areas in which their safety may be jeopardized. The barrier assemblies contain a sheet configured for outstretching and for retraction into a roll form, and for being maintained under tension in an outstretched form. A locking assembly prevents the sheet from accidentally retracting. The barrier assemblies are configured for indoor use by means of attaching to walls and stair posts as well as for outdoor use by anchoring the barrier assembly to the ground.

A lockable corner bracket includes a lockable encapsulated axle pulley which houses one end of a length of cord, with the free end secured to a side bracket. A cord locking mechanism is used to lock the encapsulated axle pulley and prevent unwinding of the cord, or loss of tension, during transport and installation to facilitate do-it-yourself installation. The axle pulley is further configured with a central slot to allow frontal insertion of a roller tube. The corner bracket may be used with a manual roller screen including roller tubes fitted with spring assist systems to facilitate winding and unwinding of the screen, or with roller tubes fitted with a tubular motor to drive rotation of the roller tube.

A lockout tool assembly for locking open a roll-up door that automatically closes without power is provided. A lockout tool assembly may include a lockout tool member, a first lockout plate, and a second lockout plate. The lockout plate may each define a receiving recess, such that when the first lockout plate and the second lockout plate are installed inverse to one another in a closed lockout alignment position, the receiving recesses are complementary in that they form a crossbar restraint receiving aperture. Methods for locking open a roll-up door with such lockout tool assemblies and for removing installed lockout tool assemblies are also provided.
