Description

The invention belongs to the field of mechanics, namely, to sliding door frames, especially those used in corner structures. These are structures where one or even both sides of the corner are covered by sliding leaves. The technical problem with this type of frames is the leaf handle, which is adjusted on its lock: when the frame shuts, the handle is very close to the second (vertical) side of the corner. As a result, access, and handling (opening - closing) of the leaf handle become difficult.
The solution proposed according to prior art is the use of gears between the handle and the locking mechanism, as in EP0505678 (B1 ) with a small displacement distance. Furthermore, the use of lifting and rolling mechanisms is proposed for robust structures, usually involving large leaves (like EP2918762 (A1 ) and EP3425149 (A1 )) -although this cannot be placed in every sliding frame-, as well as the use of a simple latch mechanism ( CN108425604 (A )) with limited practicality and safety. In EP2829673 (A1 ) an adapter is used to transfer the handle rotation to a lock placed at a distance from its rotation axis. The rotation of the handle is directly transferred to the locking mechanism, as per the prior art. No transfer of the handle placement centre is affected. Also, WO2018130861 refers to a locking mechanism which uses three gears, the handle gear, the connecting gear and the locking gear, all surrounded by a chain, which conveys the motion to the connection gear and the movement exits through an output shaft to a frame uplifting mechanism.
The present invention resolves the above technical problem by the combination of features as defined in claim 1. It ensures easy access and easy use of the handle of the corner frame leaf. Preferred embodiments are defined in the dependent claims.
The present invention briefly functions as follows:
The adaptor for handle installation transposition is mountable on a multiple point sliding door lock of a prior art frame, wherein said multipoint sliding door lock is suitable to be placed on a vertical side of a moving leaf.
The leaf features a lengthy handle on its internal side. The invention "adaptor for handle installation transposition" refers to, first of all, the locking mechanism/lock of prior art placed on the vertical side of the moving leaf, as per the prior art. The adapter mechanism, which ensures movement transmission, is mountable on the lock so that locking is made with the handle at a distance from the locking mechanism and not on the lock, as per the prior art. The adaptor for handle installation transposition consists of a component for transmitting the motion of the handle and a component for transmitting the motion to the lock; these two components work with each other and are found in closed case which features grooves allowing the movement of components. The case is mounted on the lock of the moving leaf.
The invention "adaptor for handle installation transposition" accelerates the transmission of motion from the external to the internal profile, with the handle found at a distance from the locking mechanism and allowing handling of the mechanism from a distance.
The advantage of the invention is that, by ensuring the handling of the locking mechanism with the handle preserving its distance from it, even corner openings can be covered by sliding frames featuring the mechanism, because the two sliding frames may "meet" at the corner without their handles bumping on each other. A further advantage is that the invention offers users greater visibility, as it allows coverage by glass frame for corner openings of great surface.
Moreover, an additional advantage is that the invention uses a multiple point locking mechanism to a corner structure, which is very cost-efficient and is widely used according to prior art.
Finally, another advantage of this invention is that the adaptor for handle installation transposition is not screwed on the profile but on the lock, therefore ensuring easy installation, replacement and repair of the mechanism and handles, if necessary.

There follows a detailed description of the present invention with reference to the accompanying drawings.
As illustrated in drawing 1, the invention "adaptor for handle installation transposition" is mounted on the prior art multiple point lock (3) for sliding doors, which is placed on the vertical side of the moving leave and has a handling hole (12). The invention consists of a case (20) consisting of a top-cap (1) and a base-cap (2). Within the case (20) the component transmitting the motion of the handle (5) and the component transmitting the motion to the lock (4) are placed.
As illustrated in drawings 1, 5 and 10, the top-cap (1) features within itself a through semi-circular groove (6) allowing the movement of the component transmitting the motion of the handle (5) and the component transmitting the motion (4) to the lock. The semi-circular groove (6) may feature a slot at some point. It features a through hole (15) for placing the handle (11), four screw sockets (19a) for connecting the two caps of the case (20), two through holes (21) for connecting the case (20) to the multiple point sliding door lock (3) and two through holes (22a) for connecting the handle (11) to the case (20).
As illustrated in drawings 1, 6 and 10, the base-cap (2) features within it a semi-circular groove (7) allowing the movement of the component transmitting the motion (4) and the component transmitting the motion of the handle (5), opposite to the semi-circular groove (6) of the top-cap (1). It has a through hole (16) for placing the handle (11), opposite and coaxially to the through hole (15) of the top-cap (1). It also has four through screw holes (19b) opposite and coaxially to the four screw sockets (19a) of the top-cap (1) for connecting the two caps of the case (20). It also has two holes (22b) for connecting the handle (11) to the case (20).
As illustrated in drawing 3, the invention has a component transmitting motion (4) to the lock, which features on its one end a square-cross section protrusion (9). The component (4) features a straight through groove (10) along its length.
As illustrated in drawing 4, the invention has a component transmitting the motion of the handle (5). One end of the component (5) features a cylindrical formation and the ends of this cylindrical formation (17a and 17b) protrude in equal lengths on both sides of the component, allowing proper placement of the top-cap (1) and the base-cap (2) respectively in the through holes (15 and 16) of the case. The interior of the cylindrical formation has a through hole (8) of square cross section. The other end of the component transmitting the motion of the handle (5) features on both sides two, uneven in length, coaxial protrusions (13a and 13b), with one protrusion (13a) being larger than the other (13b).
As illustrated in drawings 9 and 10, the handle (11) has a supporting axis (14) of square cross section and is based on the case with handle placement holes (18).
The assembly of the adaptor for handle installation transposition with motion transmission, is done as follows ( drawings 1, 2, 7):
First of all, as illustrated in drawing 2, the component transmitting the motion of the handle (5) and the component transmitting the motion to the lock (4) are connected. In specific, the longer protrusion (13a) of the component transmitting the motion of the handle (5) goes in the straight through groove (10) of the component transmitting the motion to the lock (4). Then, this assembly of two components (4 and 5) is placed inside the base-cap (2) of the case (20), as follows: the component transmitting the motion of the handle (5) with its one end with the cylindrical formation (17b) ( drawings 1, 2, 6 and 7) is placed in the through hole (16) of the base-cap (2), while its smaller protrusion (13b) goes in and moves within the semi-circular groove (7) of the base-cap (2). The other end of the component transmitting the motion of the handle (5), with the circular formation (17a), goes in the through hole (15) of the top-cap (1). The longer protrusion (13a) of the component (5), which has gone in the straight through groove (10) of the component transmitting the motion to the lock (4) also goes in the semi-circular groove (6) of the top-cap (1) and can move within it. The two caps (1 and 2) are screwed to one another, using the four screw sockets (19a) of the top-cap (1) and the four through screw holes (19b) of the base-cap (2). The single case (20) is thus created. The component transmitting the motion (4) to the multiple point sliding door lock (3) with its other end which has the square cross section protrusion (9), passes through the square handling hole (12) of the lock (3) and is mounted inside it (drawings 1, 2). The entire case (20) is mounted in the lock (3) of the sliding leaf with two through holes (21) ( drawings 1, 2, 7, 8, 9, 10).
As illustrated in drawings 1, 2, 5, 7, 8, 10 and 11, the through square hole (8) at the end of the component transmitting the motion of the handle (5) with the cylindrical formation (17b), is found in a coaxial position with the through hole (15) of the top-cap (1) and with the through hole (16) of the base-cap (2). The handle (11) with its supporting square cross section axis (14) goes in the case (20) via the through square cross section hole (8) of the cylindrical end (17b) of the component transmitting the motion of the handle (5). The handle (11) is screwed and stabilised on the case (20) of the mechanism, with the holes (22a and 22b). In this position, the longer protrusion (13a) of the component transmitting the motion of the handle (5) touches and moves within the semi-circular groove (6) of the top-cap (1), while the smaller protrusion (13b) touches and moves within the semi-circular groove (7) of the base-cap (2). The case (20) containing the mechanism is ready for use (drawing 8).
The operation of the invention mechanism is described below, with reference to drawings 1, 7 and 10.
Users rotate the handle (11), through the connection of the handle axis (14) which is found in the through square cross section hole (8) of the cylinder formation end (17b) of the motion transmission component (5). The rotation is transmitted to the motion transmission component (5), which makes a rotating move with coaxial protrusions (13a) and (13b), with the axis of the through hole (8) as rotation centre. The movement of the component (5) is delimited by the length of semi-circular grooves (6) and (7), as its co-axial protrusions (13a and 13b) move exclusively within the grooves (6 and 7).
The rotation of the motion transmission component (5) is transferred to motion transmission component (4), through the connection of its longer protrusion (13a), which is found in the through groove (10). Motion transmission component (4), with square cross section protrusion (9) makes a rotational move having as its centre the axis of the handling hole (12) of the multiple point sliding door lock (3) which is placed on the vertical side of the moving leaf. The square cross section protrusion (9) rotates within the square cross section handling hole (12) and activates the lock (3).
The present invention can be applied in all door openings covered by sliding frames, whether corner bypass or not.
