Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a fixed member made of a profile and connected to a frame with an upper cover, and a rotating window made of a profile and provided with a lower cover. The present invention relates to a rotating roof window pivot including a movable member connected to a body.

[Problems to be solved by conventional technology and invention] Already,
Hinges for rotating windows with external sheathing profiles are known.

This hinge is in the form of a case and is screwed into a notch formed in the frame of a movable member that is screwed onto the window body and has a bottom plate consisting of two approximately sector-shaped plates. It consists of a fixed member. The two plates rotate about the second joint axis and move within semicircular notches formed in the two walls of the fixed member. A rotary lever is provided between the two walls of the fixed member and the two plates of the movable member, which rotates about the first joint shaft and has a second joint shaft extending therethrough. This generally U-shaped rotary lever is connected at one end to the fixed member by a first articulation shaft and to the movable member at the other end by a second articulation shaft. The rotary lever also has a rotary launch on each side that rotates about an axis. In the closed position of the window, this latch is accommodated in a cutout drilled in the semicircular cutout of the fixing member. The two movable members have curved guide projections.

However, such latches cannot be used with revolving roof windows where the frame and revolving window body are made of metal or plastic sections. In fact, in order to place this hinge in place, as it is a recessed hinge, cuts must be made in the frame, which is not possible in frames made of profiles.

Furthermore, pivots for rotating roof windows are also known. The pivot is continuous with the frame and has a first pivot at one end of the rotating lever.
It includes a fixed member connected by an articulation shaft, and a movable member connected to the rotating window body and connected to the other end of the rotating lever by a second articulation shaft. These two articulation axes include an initial rotation about a second articulation axis connecting the rotating lever to the movable member, followed by a second rotation about the first articulation axis connecting the rotating lever to the fixed member. As rotation takes place, the rotating window body is displaced in the open position outwardly relative to the plane of the window body. A blocking member is disposed on the second articulation axis connecting the movable member to the rotary lever, and these means prevent the other end of the rotary lever after a first rotation of the movable member about said second articulation axis. terminating the cooperation of the elastic return clamping means with respect to a second rotation of the rotary lever about the first articulation axis connecting the to the fixed member.

However, this pivot has a major drawback.

In fact, this pivot can brake rotational movements, but is limited to normal opening functions. In short, when the rotary window body in the cleaning position is operated, there is a risk that it may rotate unexpectedly, and this rotation not only deteriorates the assembly between the pivot and the window body, but also may cause a major accident.

The present invention aims to solve the above-mentioned disadvantages of the prior art.

(Means for Solving the Problems) Therefore, the pivot for a rotating roof window of the present invention includes a fixing member made of a profile and connected to a frame with an upper cover, and a fixing member made of a profile and connected to a frame with a lower cover. and a movable member connected to a rotary window body having a fixed plate, the movable member rotating around a rotating shaft connected to a fixed member formed of sectors and constituted by a fixed plate. and, on the other hand, drive means for moving an intermediate cover filling the space between the lower singing of the upper cover of the frame and the upper singing of the lower cover of the window body to a retracted position or a predetermined position. It is characterized in that it includes a control means operated via a member that is moved in a straight line.

[Operation] Various rotational movements of the window body are always braked regardless of the angle of inclination of the window body between the closed position and the cleaning position.

The pivot is thus provided with a safety means which eliminates any risk of accidental rotation in known pivots which have only three locking positions: the closed position of the window body, the open position and the cleaning position.

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

A revolving roof window consists of a frame l made of a metal profile or plastic material and a window body 2 also made of a metal profile or plastic material. The frame l has an upper cover 3 on its upper part, and the lower singing (channel) of this upper cover 3
ant) 4 is located near the pivot 5 inserted between the spar 6 of the frame 1 and the spar 7 of the window body 2. Similarly, the window body 2 is provided with a lower cover 8 at its lower part, and this lower cover 8
The upper singing 9 of is also located near said pivot 5. The upper cover 3 is attached to the frame 1, and the lower cover 8 is connected to the window body 2. Between these fixed covers 3 and 80 is a movable intermediate cover 10, the upper singing 11 of which is located below the lower singing 4 of the upper cover 3, and the lower singing 12 of the movable intermediate cover IO.
is arranged so as to cover the upper singing 9 of the lower cover 8.

Each pivot 5 includes a fixing member formed by a fixing plate 13 connected to the frame 1. The lower end of this fixing plate 13 has a truncated conical cavity 16 on its side 15 directed towards the window body 2.
, in which a braking means is accommodated, which is constituted by a braking cone 17 cooperating with a truncated conical boss 18 of a braking pinion 19 . The brake pinion 19 is connected to the shaft 20
The head 21 of this shaft 20 is engaged with a bore 22 formed in the brake pinion 19 . The free end 23 of the shaft 20 is connected to the other surface 25 of the fixed plate 13.
It is accommodated in a gap 24 formed in. An elastic member 28 is inserted between the shoulder 26 of the head 21 of the shaft 20 and the bore 22 of the brake pinion 19. This elastic member 28 ensures the cooperation between the brake cone 17 and the truncated conical boss 18 of the brake pinion 19, which is necessary to constantly brake the rotational movement of the window body 2.

In another embodiment of the invention, the free end 23 of said shaft 20
has a thread to which a nut can be tightened. For this reason, the compression of the elastic member can be adjusted, and therefore the cooperative force of the braking cone 17 and the frustoconical boss 18 of the braking pinion 19 can be adjusted depending on the weight and dimensions of the window body 2 and the binion relative to the frame 1 and/or the window body 2. It can be adjusted according to the position of 5.

Furthermore, the fixing plate 13 moves the window body 2 to the cleaning position (see Fig. 2).
It has a groove 25 in which the upper singing 9 of the lower cover 8 moves when a force is applied to the window body 2 to cause the window to move.

The pivot 5 further includes a sector-shaped movable member 30 that rotates around a rotating shaft 31 connected to the frame l. In order to connect the sector-shaped element 30 to the window body 2, this sector-shaped element 30, with its surface 32 directed towards the window body 2, is engaged in a recess 34 of the window body 2 and has a fixing screw 35. , 36. This sector-shaped member 30 includes drive means consisting of a curved segment 37 with teeth 38 . Said teeth 38 mesh with teeth 39 of the brake pinion 19. The sector-shaped member 30 also has one end 40 of its curved segment 37 at the other surface 4 of the sector-shaped member 30.
drive means formed by control fingers 41 projecting relative to 2; If the window is in the closed position,
Said control finger 41, which lies practically in the same horizontal plane 43 as the axis of rotation 31, is on the side of the lower singing 4 of the upper cover 3 of the frame 1. This control finger 41 traces an arc concentric with the axis of rotation 31 and the curved segment 37 .

Said control finger 41 cooperates with the active singing 44 of the member to be moved in translation. This member is a sliding plate 45. This sliding plate 45 is inserted between the surface 15 of the fixed plate 13 and the surface 42 of the sector-shaped element 30. The active singing 44 has an arc shape centered on the center 46 of the rotating shaft 31. Lower end 4 of active singing 44
7 is a bearing surface 48. This bearing surface 48 is perpendicular to the longitudinal singing 49 of the sliding plate 45. In this longitudinal singing 49 and near the upper end of the sliding plate 45, a gap 51 is formed which is parallel to the bearing surface 48 and therefore perpendicular to the longitudinal singing 49.

Said gap 51 cooperates with drive means formed by a first control finger 52 provided on one end 53 of said connecting rod 54, which control finger 52
It stands out against one side of 5. The other end 5 of the connecting rod 54
6 is also provided with a second control finger 57 projecting relative to the surface 55. This connecting rod 54 is rotatable around a joint shaft 58, and one end 59 of this shaft is attached to the connecting rod 54.
The other end is accommodated in an orifice 60 formed in the fixed plate 13, and the other end is accommodated in an orifice 62 formed in the fixed plate 13. The articulation axis 58 is located between the two control fingers 52,57.

Said second control finger 57 acts on a drive means which is connected to the intermediate cover 10 and is constituted by two walls 63, 64 of the fork 65 projecting with respect to the lower surface 66 of said intermediate cover 10. do.

The operation of the pivot of the present invention is as follows.

When the window body 2 is pushed outward, the sector-shaped member 30 is rotated about a rotation axis 31 which is also fixed to the fixed plate 13 connected to the frame l. The rotational movement of this sector-shaped element 30 is immediately braked because the teeth 38 of the curved segment 37 of this sector-shaped element 30 cooperate with the teeth 39 of the brake pinion 19 . During this window opening movement, the control finger 41 of the sector-shaped member 30 moves the active singing 4 of the sliding plate 45 up to the lower end 47 of said active singing 44.
4 and comes into contact with the bearing surface 48 of the sliding plate 45. Finally, the window body 2 assumes a position perpendicular to the frame 1, and the brake pinion 19 prevents unintentional rotation in any direction.

When the window body 2 is placed in the cleaning position, the window body 2 is continuously pushed outward. Control finger 42 of sector-shaped member 30
applies pressure to the bearing surface 48 of the sliding plate 45 and moves the sliding plate straight in the direction of the brake pinion 19 while moving upward along the bearing surface 48.

During the translational movement, the sliding plate 45 applies a traction to the first control finger 52 of the connecting rod 54, causing the connecting rod 54 to rotate about the articulation shaft 58 connected to the fixed plate 13. Following said rotation of the connecting rod 54, the second control finger 56 of this connecting rod 54 is connected to the fork 6 connected to the intermediate cover 10.
5, the middle cover can be retracted under the upper cover 3 of the frame 1. When the outward rotation of the window body 2 is completed, the lower cover 8 of the window body 2 comes into contact with the lower singing 4 of the upper cover 3 of the frame 1 (see FIG. 2).

When a traction is applied to the window body 2 in order to close it, the control finger 41 of the sector-shaped member 30 moves idly (at 67) while tracing an arc 68 until it contacts the active singing 44 of the sliding plate 45 at 69. show). This arc 68
The center is the center 46 of the rotating shaft 31. The above idle (67
), the lower cover 8 of the window body 2 is moved away from the lower singing 4 of the upper cover 3 of the frame 1. When the control finger 41 of the sector-shaped member 30 comes into contact with the active singing 44 and continues to close the window body 2, said control finger 41 pushes back against the sliding plate 45. This sliding plate 45 then pushes back the first control finger 52 and rotates the connecting rod 54 about the joint shaft 58. Therefore, the intermediate cover 10 is again in the predetermined position. However, due to the idle rotation 67, the covering of the intermediate cover 10 is delayed. When the window body 2 reaches its closed position,
The intermediate cover 10 will enter the space between the lower singing 4 of the upper cover 3 of the frame 1 and the upper singing 9 of the lower cover 8 of the window body 2.
