Abstract:
A device (2) for opening and closing a door (1), with a rolling device (2') which has a shell-shaped housing (13) which is assembled from two complementary housing parts (14, 14') and in which a driving device (8) is arranged, the driving device being connected via a drive shaft (20) to a driving wheel (6) which, in a fitted operating position of the rolling device (2'), is in frictional contact with a rolling surface facing the driving wheel (6). A fixing body (15) is arranged on a housing part (14), the fixing body, together with an opposite fixing body (15') arranged on the other housing part (14'), forming a fixed bearing for the drive shaft (20). The fixing bodies (15, 15') have respective recesses (16, 16') forming a bearing seat for a bearing (21) of the drive shaft (20). A housing (14, 14') has linear guide means (12; 12'') for connection to corresponding linear guide means (12; 12') of a fastening element (4) provided for fastening to a door. The linear guide means (25) of the housing part (14, 14') are arranged adjacent to the bearing seat for the bearing (21) of the drive shaft (20). The invention furthermore relates to a method for installing such a device (2).
Abstract:
A linear actuator (10) particularly for sliding doors and for sliding door or window closure elements in general, comprising a box-like body (11), to be fixed with corresponding means of fixing between the two jambs (S 1, S2) of a door (P) or of a window or door frame, in order to move a leaf (A) by translational motion, fixed drive means being accommodated within the box-like body (11) which are adapted to move corresponding transmission means which are associated with the leaf (A). The box-like body (11) is telescopic in structure in order to be adapted in length to the width of the space of the door (P), or other window or door frame, with which it is intended to be used.
Abstract:
The invention relates to a multi-component dye unit for use in a system to protect valuables comprising at least two reservoirs (1, 2) filled with different agents A and B, and connected to a spraying device (5, 5') capable of staining the content of a secured container wherein said at least two inner reservoirs (1, 2) are arranged in an external container or housing (3, 3'). The reservoirs are preferably made of flexible material and the content thereof may be expelled by a pressurized gas produced in said external container (3, 3'). Advantageously, the external container is made of two parts (3, 3') clippable together.
Abstract:
A step unit comprises: a step member which is provided with a pair of lower rails extending in an opening and closing direction of a slide door of the vehicle; and a rail plate member which is provided to a cutout formed in a part of either of the lower rails and which continuously connects the lower rails in the opening and closing direction. A roller which is connected to the slide door is disposed between the pair of lower rails. The step member is molded using a resin material and is provided with an insertion hole which vertically penetrates through the step member at a position corresponding to the cutout; and a support extension section which is extended from a side end of the cutout of the lower rail so as to support the rail plate member against a load which the rail plate member receives from the roller. The rail plate member is mounted to the step member by being inserted so as to penetrate through the insertion hole from above the step member.
Abstract:
A support structure for leaf shutters (2) comprises two facing uprights (4,5), an upper cross-member (6) connecting together said uprights (4,5) and hinges (8) for enabling the shutter leaves (3) to rotate. Advantageously the hinges (8) fixed to a respective upright (4,5) are positioned so as to have their respective axes of rotation substantially aligned together along a straight line (X-X) intersecting the upper cross-member (6). Furthermore the upper cross-member (6) defines a housing (9) suitable for housing actuating means (12) for actuating the shutter leaves, so that the actuating means (12) have a rotating shaft (13) extending in alignment with the axes of rotation of the hinges (8) of a respective upright (4,5).
Abstract:
Motor unit (Mn), used in an actuating system for moving gates, in particular gates of the leaf type, and comprising a motor for moving the gate enclosed in a housing, a control unit (Cn) connected to the motor for managing operation of the motor unit and peripheral devices (Qn) and contained inside the housing, characterized in that it comprises only one twin-wire line (Wn) for the transmission of signals between the control unit (Cn) and the peripheral devices (Qn).
