GR1009504B - Lock for industrial rolling shutters - Google Patents

Abstract

Novelty: a lock destined for use in industrial rolling shutters is disclosed. Constitution-function: the invention is composed of the closure means (plate-spring) 1 set at the lower part of the rolling shutter, the striking plates 2 of said closing means, the wire rope transmitting the motion to the pins (4α,4β), the springs of the pins (5α,5β), the button 6, the striking plate 7 of this last set at the top of the guides of the rolling shutter, the stabilizer 8 encountered at the back of the last louver, the ends (α,β,γ,δ) of the springs (5α,5β) and the locking point X . The locking and unlocking command is transmitted from the button 6, via the wire rope, to the closure means which along with its striking plates definitively locks and unlocks the rolling shutter. Advantage: no human intervention is required for locking and unlocking the rolling shutters; potential manual unsecuring of these last is allowed in case of power failure.

Description

Description

Industrial roll lock

The invention refers to a lock that fits on industrial rolls, which types are widely available on the market.

The industrial roll lock consists of two shutters at the bottom of the roll, two shutter counters, wire ropes for driving the pins, the pin springs, left and right buttons with their counters at the top of the roll guides and finally two stabilizers at the bottom, behind the last blind of the roller.

Locks of this type are not known.

Locks of this type have the ability to lock and unlock the roll at the bottom, with a mechanical movement and not an electric one, creating the lock-unlock command from the movement of the roll itself.

By using this lock, you are able to operate the industrial roller by means of a remote control or a fixed switch without the need for human intervention in locking or unlocking, but at the same time, in any power failure, it leaves intact the use of the manual locking of the roller.

The industrial roll lock according to the present invention has the characteristic that

a) has the same mechanism throughout the height and on the left and right guide of the roll. [ work in pairs ]

b) it is divided into the upper part [ command ] and the lower part [ lock] c) it locks on the lower part of the roll [ left - right ]

d) receives a command to lock and unlock the roller guide from the top. [ left right ]

e) between the lock there is a wire rope for the drive transmission.

With the shutter ( 1 ) [ see figure 1 ] and the corresponding reflection

of shutters ( 2 ) [ see figure 1] it is enabled to perform the lock-unlock command since the shutter feedback (2) is able to rotate on its axis and lock the shutter (1) or release it accordingly.

In order to be able to receive the lock-unlock command (mechanically) the shutter reaction (2), from the upper part of the roller guides, there is the wire rope (3) [see figure 1 ]

The wire rope ( 3 ) is tied between two pins ( 4 a - 4 b )

[ see figure 1 ]

where they in turn pass through two springs (5 a - 5 b) [see figure 1 ]

The ends of the springs ( b - c) [ see figure 1] is tied to the edge of the pins (4a-4b) while the edge of the springs (a-d) [see figure 1 ] are firmly attached to the roll guide.

The springs (5 a - 5 b) are stretched while increasing their mechanical strength, as a result, the wire rope (3), always find the pins (4 a - 4 b) which are the ends of the wire rope (3) stretched to be in balance between the two springs (5 a - 5 b).

The button ( 6 ) [ see figure 1 ] at the top of the guide is

united with the pyro (4a) and the counterpoint of the button (7) [see figure 1 ] is attached to the opposite blind of the roller from the button.

When the roller is completely closed, the reaction of the button (7) presses the button (6), causing the pin (4a) connected to the button (6) to move downwards. The wire rope ( 3 ) is no longer balanced and the pin ( 4 b ) is released at point ( X ) [see figure 1 ] of the back of the shutter (2).

The shutter stop (2) cannot be rotated on its axis and blocks the shutter (1) with the result that the roll cannot be opened further.

To unlock, you rely on the margins - gaps that exist between the blinds of the roll.

These enable there to be a time difference between

of the button facing (7) and the shutter facing (2).

The push-back of the button (7) starts first with the movement of the roll and until all the margins - spaces of the blind are opened, the pin (4 b) has had time to move from the point (X) of the push-back of the shutter (2).

That is, the button (6) is no longer pushed down, the pins (4a - 4b) and the wire rope return to balance, the pin (4b) leaves the point (X), the shutter reaction (2) rotates against its axis, the shutter (1) is released, so the roll is now open.

In manual locking it works again.

The roller is disengaged from the motor and the load of the mat [the set of blinds] of the roller is lifted by the springs of the shaft, so the mat starts and you move, as a result the reaction of the button (7) does not push down the button ( 6) the pins (4 a - 4 b) and the wire rope return to balance, the pin (4 b) leaves the point (X), the shutter stop (2) rotates against its axis, the shutter (1) is released so the roll is now open.

The stabilizer ( 8 ) [ see figure 1 ] is only to hold the last blind in place.

Claims (4)

Claims Industrial roll lock 1) The industrial roll lock consists of the shutter ( 1 ) at the bottom of the roll and the shutter counter ( 2 ) which has the characteristic of rotating along its axis, which enables it to release or lock the shutter, include the roll, by choice. 2) The wire rope ( 3 ) for driving the pins ( 4 a - 4 b ) and the pin springs ( 5 a - 5 b ) have the characteristic that their combination keeps the two pins in balance between the springs and can they mechanically transfer an order [open - close] or else I balance I don't balance. 3) And finally the button ( 6 ) and its reflection ( 7 ) at the top of the roll guides as a combination, their characteristic is that they create the basic command lock [ button pressed - no button pressed ] . 4) The industrial roller lock works all together as a set of movements and its biggest advantage and characteristic is that the mechanical movement of the lock goes along with and follows the electrical movement of the motor.
