Description

Glass frame opening by projection towards the outside of the facade of a building then by translation in front of the adjacent parts of the facade without their involvement in its operation.

The invention relates to a glazed frame to be included in any facade or part of a building facade, the external face of the components of which is aligned in the same vertical plane, opening consecutively by projection towards the outside and lateral translation without involving the adjacent components, and capable of the performance, in terms of air and water tightness, of a chassis known as impact.

Contemporary architecture frequently involves the creation of facades in which the glazed parts. fixed or opening, and the opaque parts are aligned externally in the same plane, or even confused by a total identity of appearance, whether these are components with visible structure or smooth components, for example facades with cladding stuck glassmaker. In this type of structure, the layout of the facade is most often expressed by hollow and narrow joints between the various components, an arrangement which limits the methods of opening the opening parts. The type of opening most generally used is the opening by projection towards outside known as “with the Italian”. This type of operation presents two disadvantages; The user has a view to the outside only through glazing which, depending on its nature can cause alteration of natural colors, and ordinary cleaning of the exterior face of glazing is only possible the condition of an exceptional chassis maneuver most often reserved for specialized personnel. A remedy to the first of these drawbacks is proposed in the form of a so-called "oscillating swing" opening which can only be effectively used in the case of narrow bays, the most common frame of the façades of buildings in the tertiary sector causing deflection of opening it inward too large for proper use of the premises.

The present invention aims to remedy these drawbacks by providing a mode of operation of the opening such that the user has in order a first so-called ventilation opening at the end of which the bay remains protected from rain, then a complementary opening offering it both direct vision towards the outside and the accessibility necessary both for cleaning the outside of the opening itself and for cleaning the outside of the components adjacent.

The invention is described below in detail using drawings showing the operating principle and showing only one embodiment.

Figures 8, 9 and 10 show an embodiment of the command to project the glass frame.

Figure 8 is a horizontal section on one of the uprights of the frame showing the control members in the closed glass frame position.

Figure 9 is a vertical section on one of the uprights of the frame in the plane A-A parallel to the plane of the facade (see fig. 10) showing the control members in the closed glass frame position.

FIG. 10 is a vertical section on the lower part of one of the uprights of the chassis in the plane BB perpendicular to the plane of the facade (cf. fig. 9) showing the control members in the open glass frame position at 10a, and closed glass frame lOb.

In accordance with the present invention, the frame 1 of the chassis is made up of a U-shaped profile whose core is located in the plane of the chassis on the inside of the facade, and whose wings, equal or unequal, are perpendicular to the plan of the facade. A horizontal slide 2 perpendicular to the plane of the facade is fixed to each of the four angles of the frame 1 on one or the other of the internal faces of the wings of the U-profile constituting its uprights.

A cross member 3 secured at each of its ends to a single 4 or double and telescopic slide 4a-4b engaged on the slide 2 and moving in a horizontal plane and in the direction perpendicular to the plane of the facade is inscribed in each of the two sleepers of the sleeping frame 1 between the wings of the U-shaped profile. The sleeper 3, the dimensions of which are compatible with its free movement in the direction perpendicular to the plane of the facade, comprises, on its face turned towards the exterior of the facade, a continuous square-shaped appendage whose end of the horizontal wing 3a is integral with the cross-member 3 and whose vertical wing 3b is parallel to the plane of the facade and directed towards the outside of the frame to be used as a rail and to form with the horizontal wing 3a and the external face of the cross-member 3 a continuous channel 3c.

Still in accordance with the present invention, the opening glass frame 5 is, on the face turned towards the inside of the facade of its top and bottom crosspieces, provided with a continuous U-shaped appendage whose core, horizontal and perpendicular in the plan of the facade, is turned towards the outside of the chassis and one of the wings 5a is attached to the face of the frame 1 and the other Sb is diri-ged unlike the rail 3b of the associated profile 3 to the frame 1 to form a channel 5c overlapping the rail 3b.

We see at this stage, that the glazed frame 5, carried by the rail 3b of the movable cross member 3 will be projected outwards in a plane parallel to the plane of the facade if a horizontal thrust is exerted simultaneously on the slides 4 associated with the sleeping frame 1 via the slides 2.

 It can also be seen that after sufficient projection has been obtained so that the innermost face of the glazed frame 5 is brought beyond the exterior plumb of the adjacent components of the facade, the said glazed frame 5 can be translated on one side. or on the other side of the bay as far as it is compatible with its good cantilever behavior with respect to the rails 3b which support and guide it.

Air and water tightness between the glazed frame 5 and the sleeping frame 1 will be obtained during closing by compression of appropriate seals 6 and 7, located between the inner face of the glazed frame 5 and the ends of each of the wings of the U-shaped profile constituting the frame 1 and secured to one or the other of these frames.

The example of execution in aluminum joinery (cf. fig. 5,6, and 7) shows that, in accordance with the invention. the movable cross member 3 located in the upper part of the chassis comprises at the base of its face turned towards the inside of the facade a continuous 3d appendage exceeding the level of its upper face.

We then see (see fig. 6b) that when the glazed frame is projected for ventilation, the rainwater flowing on the facade is collected on the upper faces of the glazed frame and the movable cross member 3 before falling into the channel 3c to evacuate on either side of the bay through the open ends of this channel.

It can also be seen that the water which could accidentally infiltrate through the seal 6 is collected by the same channel 3c and then, by gravity, drained into the uprights of the frame 1 to be discharged to the outside by the drainage holes 8 formed in the bottom cross member of this same frame.

According to the invention, the projection of the glazed frame can either be controlled manually by any rod and rod device acting simultaneously on the four slides 4, or by flexible cables or rack cables having the same effect, or be slaved to the operation of cylinders, pneumatic, hydraulic or electric, also acting on the four slides 4.

By way of example, FIGS. 8, 9 and 10 show a manual control device in which a rotary lever 9 fixed on a side face of one of the uprights of the frame 1 actuates by means of a toothed belt or of a chainelO, a cam 11 rotating inside the U-shaped profile of the same amount in a vertical plane parallel to the plane of displacement of the slide 4 and acting simultaneously on a lug 12 fixed on the vertical face of the slide 4 and moving in the horizontal direction perpendicular to the plane of the facade, and on a lug 13 secured to a rod 14 sliding vertically in a groove ic located on one of the internal faces of the wings of the U-profile of the frame 1.

The sliding rod 14 controls, at the other end of the upright, by means of a lug identical to the lug 13, a cam identical to the cam 1 sliding on the slide 4 by a lug identical to the lug 12.

A symmetrical device equips the other upright of the sleeping frame. The synchronization of the operation of the two devices can be ensured in two ways.

In the first case, the two control levers are connected by a rigid tube acting as a single handle.

In the second case, the cams 11 comprise a toothed sector 1 1 a acting on pinions 15 integral with the ends of a transmission shaft 16 situated behind the movable cross member 3 inside the U-shaped profile constituting the cross member of the frame 1.

A lever handle fixed on a lateral face of the frame 1 and acting directly on one of the sliding rods 14 can in this case be substituted for the levers 9 and belts 10.

We see according to this example that the slides 2 can be fixed on the brackets 20 and 21 and that the cams 1 1 and the toothed wheels 15 can be articulated on these same brackets before the tab assembly of the components of the frame 1 in order to simplify the use of these members.

It can also be seen that according to this example, the slide 4 can also consist of two slides 4a and 4b which move relative to each other by half of the stroke in order to reduce the stresses due to its behavior in console.

The translation of the glazed frame 5 is controlled either manually using an index 17 fixed on the inner face of the uprights of the frame or controlled by any command, automatic or not, acting on any type of jack. Stops 18 and 19 disposed respectively on the outer face of the movable cross member 3 and on the inner face of the glass frame limit the travel of the latter or prohibit, if necessary, translation in one or the other of the directions in the event of obstacle to opening.

The example of execution shows that any anti-friction material or material 22 may be interposed between the rail 3b and the walls of the channel 5c to reduce the effort to be exerted to obtain the translation of the glazed frame 5.
