Description

Locks opening and closing device of doors.

The present invention relates to a opening and closing device for door locks, preferably with overhead doors, of the type used for parking access.

Background of the invention

Currently, different types of Doors that are used for parking access. A type of door is known as a swingarm, which comprises a part upper and lower part joined by a rotation axis horizontal. In this way, when you open the door, the top turns inwards and the bottom turns towards Exterior.

To drive these door movements, The opening and closing devices comprise a motor. These Devices can be mechanical or hydraulic.

These doors also comprise a lock, which must be opened and closed before the movement of the door. The Opening and closing the door lock can be performed manually or by said engine.

The opening and closing devices of the currently known door lock are hydraulic and electrical, and have the disadvantage that they are excessively expensive

To solve this problem, the opening and closing device described in the utility model U200601922, of the same holder of the present application.

This document describes a device that  comprises a transmission element connected to the engine that press a tilting piece, which is movable between a closing position and an opening position of the lock. Although this device perfectly fulfills its function as open and close the door lock and it is substantially more cheap than hydraulic and electrical devices conventional, it has been seen that it is possible to simplify it, making it even cheaper.

Description of the invention

With the opening and closing device of the invention manages to solve the aforementioned drawbacks, presenting other advantages that will be described.

The opening and closing device of door locks of the present invention comprises an engine that drives the door, and a transmission element, associated by one of its ends with said motor, movable between a position opening of the lock and a closing position of the lock, and is characterized by the fact that it is formed by two pieces articulated with each other, so that in the position of lock closure said parts are substantially aligned with each other, and in the open position of the lock These pieces form an obtuse angle.

Thanks to this feature, the device is  even simpler than the one mentioned above and, therefore, cheaper.

According to a preferred embodiment, said element transmission is associated at the opposite end of the engine with a body movable between a locked position of the lock and an opening position of the lock.

Advantageously, said movable body is associated with the lock by means of a cable, and said end opposite to the engine of the transmission element and the body Scrollable are housed in a guide profile.

Brief description of the drawings

For a better understanding of how much has been exposed Some drawings are accompanied in which, schematically and only to non-limiting example title, a case study of realization.

Figure 1 is a schematic elevation view side of the opening and closing device of the present invention, in its locked position; Y

Figure 2 is a schematic elevation view side of the opening and closing device of the present invention, in its opening position of the lock.

Description of a preferred embodiment

As can be seen in the figures, a overhead door, generally identified by reference numeric 1, comprises a motor 2 and a lock 3. Said motor 2 activates the opening and closing of the lock 3 by means of the opening and closing device of the present invention.

The device of the present invention it comprises a transmission element 4 formed by two parts 4a, 4b articulated with each other. In the embodiment depicted, the parties 4a and 4b are two curved bars.

This transmission element 4 can be placed in two positions: a lock opening position (represented in figure 2) and a closing position of the lock (represented in figure 1).

In the closed position, both parts 4a and 4b are substantially aligned with each other, while in the open position they form an angle
obtuse.

Said transmission element 4 is associated in  its upper end to the motor 2 and at its lower end to a scrollable body 5, which can also be placed in two positions: one of closing and one of opening, corresponding to said positions of the transmission element 4.

Both the end of part 4b of the element of transmission 4 as the scrollable body 5 are housed in a guide profile 7, which guides its movement.

Said movable body 5 is connected to the  lock 3 via a cable 6, so that when the cable is tense the opening of said lock 3 is caused, and when not it is tense, said lock 3 is closed.

The operation of the device of the present  invention is as follows:

When lock 3 is closed and desired to open it, said motor 2 must be operated. However, it must be it is understood that lock 3 can also be opened manually, with its corresponding key.

When the engine 3 is driven, it causes a slight rotation of part 4a connected to motor 3 of the element of articulation 4. This rotation is counterclockwise according to the figure 1, and causes the rotation of the other part 4b of the element of joint 4 in the opposite direction, since both sides are articulated

When this rotation of part 4b occurs, its end causes the downward movement of the body movable 5, approximately 5 cm, causing the cable 6 tense and open lock 3.

To close lock 3 when it is open the motor 2 is driven to drive the rotation of the transmission element 4 in the opposite direction. In this way, the Sliding body 5 will be placed in its closed position and it will cause the cable 6 to not be tense, so that the lock 3 will close.

Although reference has been made to a concrete embodiment of the invention, is evident to an expert in the matter that the opening and closing device described is susceptible of numerous variations and modifications, and that all the mentioned details can be replaced by others technically equivalent, without departing from the scope of protection defined by the appended claims.
