- The solution most commonly and widely used for residential buildings, being the technology of mounting of such mechanisms, either on the door upper egde and/or the door lower edge away from its rotation shaft, in a fixed position by means of an arm.
- By developing of modern buildings, where the entrance doors are mostly made of glass, automatically controlled underfloor door closing mechanisms have been provided, said being mounted in an especially dug ground hole of significant dimensions - usually of the order of 30 X 15 cm to 6 cm deep-, enabling the glass door lower end to be fastened on a metal clamp in a fixed position, by means of an arm resulting to an underfloor mechanism pin reception hole.
- Moreover, these mechanisms already known, are equipped with some latching system being capable of defining one and only particular latching process initiation degree, -said degree normally being approximately the 12° position, prior to closing-, for lock tongue resistance elimination and door closing achievement.
- Prior technology floor mechanisms are at a disadvantage for the reason that, they provide no option other than the particular 12° position for defining and fixing of latching initiation process, for lock tongue resistance elimination and door closing achievement they are also being incapable of providing safe door opening up and parking beyond ±90° and as mentioned above, they are relatively bulky and their installation process is being time consuming and costly.

A housing (5) for supporting of a front bearing (10) and a housing (6) for supporting of a rear pair of bearings (12), monitoring the eccentric motion and locating of pins (11) for fixing of said front bearing (10) onto a six-gear splinted shaft (3).

- Said latching control system consists of a round plate (38) bearing a specially designed circular groove (39) of uneven depth engraved in its internal surface, said round plate (38) being seated inside the rear cover (21) and fastened onto the piston cylinder (18) by means of screws (8)· a safety valve (52) bearing a tension regulating screw (43), a spring (42), an oil safety ball (41), a pressure relief shaft (40) and a spring safety pin (47), for prohibiting dislocation of round plate (38) towards the oil compartment during the latching regulation, being characterized in that, it is by means of the uneven depth of said circular groove (39), that becomes capable of defining latching activation at any degree appropriate within the arc ranging from 12° to 0°, depending on each particular door dimensions, in order that the push desirable is applied for effective door closing achievement.
- Additionally, said system is characterized in that, is being capable of relieving any excess over the tolerable pressure, by means of the safety valve (52) - i.e. in case of excess pressure creation, either because of violent door pushing and/or mishandling in general-, so that any risk of damage is eliminated and safe and perfect mechanism operation is secured.
- Said tightening system consists of a shaft-carrier (9) in combination with a conical pin (45), a tightening screw -morso- (46), a six-geared splinted shaft (3) and a cam (15) bearing integrated upper and lower heart shaped configurations (14), as well as a special peripheral configuration, enabling the linear guitar-piston movement (2) within the area of -90° - 0° - +90°, as well as providing the stations A, B, Γ and Δ a corner contact bearing (31) for mounting of the shaft-carrier (9) upper part and a ring plate (32) for mounting of said shaft-carrier (9) in the mechanism main body bottom a radial load receiver bearing (33) on said shaft-carrier (9) and a sealing ring -O ring-(34), around its upper end and is characterized in that, the central shaft-carrier (9) is capable of being expanded, so that in combination with the insertion of said conical pin (45) and tightening of screw -morso-(46), firm tightening and locking of said central shaft-carrier (9) onto the cam (15) is being achieved. It is also being characterized in that, said cam (15) apart from Station A - door opening of 90°-, carries additional Stations B, ┌ and Δ specially designed, enabling the door parking past the ±90° positions and specifically at opening positions of ±135° - Station B, ±165° - Station Γ - and Station Δ -180°- and moreover, in that the mechanism is capable of being rotated up to 360° with suffering no damage whatsoever.
- By door being rotated, the cam movement (15) is being followed by front bearing (10), while threaded return spring (7) is being compressed by means of piston (2), until the 90° door rotation is reached and cam station A is found, corresponding to open door position. During this process the oil being in first oil compartment (29) passes through to second oil compartment (30), by means of non-return valve (27).
- By pushing, the door is being disengaged from cam station A and piston (2) is being pushed, by means of threaded return spring (7), while, at the same time the bearing (10) is being driven away, thus resulting to mechanism being rotated from 90° to 0° position -closed door position-.
- During this phase, the oil being in second oil compartment (30) that is not allowed to escape towards the first oil compartment (29) through the non-return valve (27), for its passage is being blocked by the safety oil ball (41), escapes into the oil gate (49) and thereof into the oil circulation pipe (50), where its flow rate is being regulated by means of door speed rotation regulation valve (22) for achievement of smooth closing and following this, returns to the first oil compartment (29) via the oil gate (51).

- By door reaching the appropriate latching activation degree, the oil safety ball (41) is being pushed by means of pressure relief shaft (40) and the safety valve spring (42) is being compressed, thus, oil passage way is being opened through second oil compartment (30), towards first oil compartment (29), whereby the mechanism rotational movement is being accelerated with direction towards the 0° position -closed door-, resulting to neutralization of lock tongue obstacle and achievement of smooth door closing.
- Said door closing mechanism is capable of being constructed in various dimensions so that, different uses and needs to be covered, as well as, may be manufactured by any metal material considered suitable for the this purpose.

- A door closing mechanism, as in claims 1, 2, 3, 4 & 5, characterized in that, it is capable of relieving any excess pressure, in case of a force exercised being greater than that tolerable secure by the mechanism, during door rotation from 90° to 0° and more specifically, the safety valve spring (42) is being compressed, by means of said force being exercised on oil safety ball (41) by the pressure relief axis (40), thus any excess pressure having been created within the second oil compartment (30) is being released, eliminating any mechanism damage risk and securing smooth and safe operation.
- A door closing mechanism, as in claims 1, 2, 3, 4, 5 & 6, characterized in that, the push desirable of said safety valve (52), is capable of being regulated by means of said regulating screw (43).
- A door closing mechanism, as in claims 1, 2, 3, 4, 5, 6 & 7 characterized in that, it functions as follows: by door being rotated towards the 90° direction the cam movement (15) is being followed by front bearing (10), while said coil return spring (7) is being compressed by means of piston (2) and when the 90° door rotation position is reached corresponding to cam station A, i.e. the open door position, the oil being in first oil compartment (29) passes through to second oil compartment (30), by means of said non-return valve (27)· by further pushing, for door being disengaged from cam station A, said piston (2) is also being pushed, by means of said coil return spring (7), while, at the same time said bearing (10) is being driven away, thus resulting to mechanism being rotated from 90° to 0° position -closed door position· during this phase, the oil being in second oil compartment (30) not being allowed to escape towards said first oil compartment (29) through said non-return valve (27), for its passage is being blocked by said safety oil ball (41), escapes into the oil gate (49) and thereof into the oil circulation pipe (50), where its flow rate is being regulated by means of said door speed rotation regulation valve (22), for achievement of smooth closing and via said oil gate (51) returning to said first oil compartment (29).
