Abstract:
This invention was developed to be used in civil or industrial rolling shutter With the purpose solution, it's possible to stop the falling of rolling shutter when the spring of enslavement, at motor o manual mechanism, breaks. In reality the device is made by a square mechanical shaft that may rotate few degrees respect an octagonal rotating tube, according with a mechanical device, in two torsion springs, one with a great torque and the other with a little opposite torque, in two gears, one rotating, the other fixed that may fit together, in one compressing spring and some other parts for mechanical connection. In normal working the powerful spring torque goes over the opposite little one obliging the devise to have a precarious position, however stable. In this position the gears are far each other and the octagonal tube may rotate winding or rewinding the rolling shutter. When the enslavement spring, which has the bigger torque, breaks, the device is obliged to move immediately toward a more stable position in which the rotating gear is strongly fit with the fixed gear. This position stops any rotation of the rotating gear and consequently the fall of the gate.

Abstract:
The invention relates to a tubular actuator (1) for a home automation screen, that comprises: a stationary point (20; 220; 420) at least partially imbedded in the tube through one end thereof; and stop means (21, 11; 221, 211; 321; 421, 411 ) of the stationary point at least in translation relative to the tube, characterised in that the tubular actuator includes locking means (32; 232; 432) for the stop means.
Abstract:
A bracket includes a rigid member that can be fastened to a fixture such as a wall, and flexible elements depend downwardly from the rigid member and are engaged with a tubular motor assembly of a window covering, awning, projector screen, or the like, to couple the motor assembly to the fixture while attenuating the propagation of vibrations from the tubular motor assembly to the fixture. This reduces noise in the room. The flexible elements may be flexible strings, elastic strings, or coil springs and have horizontal stiffness coefficients much lower than the vertical stiffness coefficient.
Abstract:
The invention concerns a guide device for a winding shaft (4) of a material handling door (1) comprising vertical members (2, 3) including in their upper part a bore (11) traversed by the actuator (13) of the shaft (4) such that each bearing (14, 15) co-operates with a plate (16) fixed on the profile of the vertical members to guide said shaft (4) in rotation, while the bore (11) comprises means for braking the actuator (13) when a bearing (14, 15) and/or the corresponding plate (16) is broken thereby preventing the shaft (4) from falling vertically and for lowering the flexible curtain.
Abstract:
The invention relates to a drive device for a rolling door. In said device, the distance between the rotational axis (6) of the winding shaft (5) which receives the door leaf, and the lintel (2) of the door opening (1) which is to be closed is adjusted. Said adjustment takes place, based on the closed or open position attained by the door leaf, in relation to the inbound or outbound alignment thereof on the guides (3) for said door leaf which are provided on each side of the door opening. The distance adjustment is at least approximately synchronised with the closing and opening movement of the door leaf. The adjustment in the distance of the rotational axis (6) of the winding shaft (5) is carried out by the bearings (7) of said winding shaft (5) which are guided along a displacement path which lies at least approximately in a straight line in relation to corresponding consoles (10) which can be arranged on either side of the door opening (1) in the lintel area. Said distance adjustment occurs between the bearing blocks of the winding shaft and the consoles allocated thereto in a reliable, quiet manner which requires little maintenance, in addition to involving minimal friction losses. The adjustment takes place in such a way that the substantially straight-line guidance system of the bearings (7) in relation to the consoles (10) consists of at least one four-link drive chain (1 to 4; levers 14, 15) running through each bearing (7) and corresponding console (10).
Abstract:
Supporting means for a window screening device comprises a first pair of bracket members (6) for mounting on each of a pair of opposed parallel frame surfaces (2) of said frame structure and a second pair of coupling members (7) engageable by said screening device. Each bracket member comprises a relatively flat front part protruding from the frame surface and having a substantially smooth external surface, whereas the engaging means (11-12; 111-112; 33-34) is provided by each coupling member (7; 107; 207; 307; 36) and comprises first engaging means in the form of at least one contact surface on the coupling member engaging a circumferential surface part of a bracket member to provide temporary engagement therewith and non-resilient second engaging means providing stable engagement of the coupling member with respect to the frame structure.
Abstract:
The present invention is directed to a rolling protective shutter (10) having improved shutter tracks (72). The improved shutter tracks (72) according to the present invention include an improved stopping mechanism (92) that prevents the shutter (30) from completely rolling up onto the shutter support member (20), provides for adjustment of the position where the shutter (30) will stop as the shutter (30) is rolled up onto the shutter support member (20), and is hidden within the shutter tracks (72). The improved shutter tracks (72) according to the present invention further include an improved cover assembly for use in concealing angle brackets (104) and the associated attachment hardware (110, 112) when a shutter track (100) is angle mounted to a wall (102) or jamb. The cover assembly completely encloses the angle bracket (104) to give the shutter track (100) and, consequently, the rolling protective shutter (10) a finished appearance after installation.
