Description

The present invention relates to the technical field of sliding doors giving access to a dwelling, a building or an industrial or commercial building in the general sense.

Conventionally, a door unit comprises at least one sliding access door comprises a peripheral frame with a lateral mounting upright for a fixed lateral screen delimiting a passage or access opening with a lateral upright extending to the opposite the mounting amount of the fixed screen. This access door also includes a sliding leaf intended to be moved in order to occupy, on the one hand, a position for closing the opening and, on the other hand, an opening position in which the sliding leaf is positioned in screws. opposite the fixed side screen. Generally, the sliding leaf is moved using an electric motor whose control is carried out using a control system comprising a selection table or desk fixed on the peripheral frame.

Of course, a sliding access door must be equipped with various systems or equipment to comply with the safety rules for users. It is thus implemented protection systems against the risk of crushing and shock with a user during in particular the opening cycle. It is thus known to implement electronic detection systems, some of which are replaced by arrangements to avoid significant additional cost.

To avoid the phenomenon of crushing when the leaf passes from its closed position to its closed position, one solution consists in making a sliding pocket with brick partition, that is to say mounting a protective screen to extend in vis-à-vis the fixed side screen to define therebetween a housing adapted to receive the sliding leaf in the open position. However, a dangerous point appears on the protection screen when the sliding leaf reaches the end of the opening stroke. To protect against crushing which may occur between the protective screen and the sliding leaf, the stroke of the sliding leaf is stopped so that a safety distance remains with the protective screen. This constraint leads the sliding leaf to protrude into the opening, which reduces the passage width for users.

The present invention aims to remedy the drawbacks of the prior art by proposing a sliding door block designed to comply with safety rules for users while having a limited cost and an optimized width for the opening of passage for users. .

The present invention relates to an access door block comprising a fixed lateral screen and a protective screen extending opposite to define therebetween a housing for receiving in the open position, a leaf sliding in a direction sliding intended to be moved to occupy a closed position of an opening.

The object of the invention relates to a door unit B comprising an access door 1 in the example illustrated in FIGS. 1 to 5, and two access doors 1 mounted in mirror or spade position as in the example illustrated in FIGS. 6 and 7. The door unit B is intended to be integrated into a wall so that the access door or doors allow passage between the exterior side E and the interior side ï of a dwelling, building or of a building in the general sense. Conventionally, the door 1 comprises a peripheral frame 2 consisting of a first vertical upright 3 and a second vertical upright known as a fixing upright 4 extending parallel to the first upright. The first upright 3 and the second upright 4 are connected to each other at their upper parts by a cross-member or transom 5.

The door 1 comprises a fixed lateral screen 7 and a protective screen 8 extending opposite and at a distance from each other to define therebetween, a housing 9 for receiving a sliding leaf 11 when this the latter occupies its open position, so that the door is said to have pocket partitions. The fixed lateral screen 7 is located on the outside E while the protective screen 8 is located on the inside I. The fixed side screen 7 and the protective screen 8 are fixed by any appropriate means to the vertical upright fixing 4.

The fixed side screen 7 can be made in any suitable way. According to a preferred embodiment, the fixed lateral screen 7 comprises a fixed lateral wall 7a mounted contiguous to a central frame 7b which has an opening edge 7i which extends away from the first upright 3 to delimit with this upright, a free access passage between the outer side E the inner side I, intended to be closed by the sliding leaf 11. For this purpose, the sliding leaf 11 has a closing edge lli intended to cooperate in the closed position, with a closing amount which defines with the closing edge lli of the sliding leaf, an opening 12 of width L allowing passage between the outside side E and the inside side I. The opening 12 has a width L zero in the closed and maximum position in the sliding leaf opening position.

The fixed side screen 7 can be made of any suitable material while being glazed, open-plan or full. In the example illustrated in Figs. 1 to 4, the fixed side wall 7a is glazed while in the embodiment illustrated in FIG. 5, the fixed side wall 7a is a masonry wall. The central frame 7b of the fixed side screen 7 is advantageously in the form of a post in the embodiment illustrated in FIGS. 1 to 4. This central frame 7b can be more or less overhanging with respect to the masonry wall as illustrated in FIG. 5. It should be noted that the opening edge 7 _t of the fixed side screen corresponds to the edge of the fixed side screen, close to or closest to the opening 12.

According to a first alternative embodiment, the central frame 7b of the fixed side screen 7 has a width I adapted to be provided with an opening control system 13 for the sliding leaf 11. This control system 13 may include a table, screen or selection desk for example. Typically, the central frame 7b of the fixed side screen 7 has a width I of between 100 mm and 400 mm. It should be noted that the central frame 7b of the fixed side screen 7 can be adapted to receive various other items of information equipment, for example.

According to a second alternative embodiment, the central frame 7b of the fixed side screen 7 has a reduced width I of between 10 mm and 100 mm.

The protective screen 8 can be made in any suitable way. According to a preferred embodiment, the protective screen 8 comprises a protective wall 8a mounted contiguous to a central frame 8b delimiting an opening edge 8i of the protective screen extending at a distance from the first vertical upright 3. The opening edge 8i of the protective screen 8 corresponds to the edge of the protective screen, close to or closest to the opening 12. The protective wall 8a is made of all materials by being glazed, with a clear view or full. For example, this protective wall 8a can be pivotally mounted to allow access to the internal face of the fixed side wall 7a. It should be noted that the protective screen 8a can be replaced by a protective radar when closing. The central frame 8b of the protective screen 8 is advantageously in the form of a post.

The sliding leaf 11 is intended to be moved between an opening position of the opening 12 and a closing position of the opening 12 allowing access between the outer side E and the inner side I. This opening 12 is delimited between the closing edge lli of the sliding leaf 11 and a closing upright with which the closing edge lli of the sliding leaf 11 cooperates when the latter occupies its closed position.

In the exemplary embodiment illustrated in FIGS. 1 to 5, the sliding leaf 11 has a closing edge lli coming to cooperate with the first upright 3 said closing forming part of the peripheral frame 2. According to this alternative embodiment, the opening 12 is delimited between the closing edge lli of the sliding leaf it and said closing amount 3 of the peripheral frame 2.

In the exemplary embodiment illustrated in FIGS. 6 and 7, the door unit B has two similar access doors 1 mounted head to tail so that the two sliding leaves extend in the same plane for in combination, close or open the passage between the outside side E and the interior side I. The door unit B thus comprises two access doors 1 called left and right, each comprising a fixed lateral screen 7 and a protective screen 8 extending opposite to define therebetween a housing 9 for receiving in the open position, a leaf 11 sliding in a sliding direction T and intended to be moved between an open position and a closed position of an opening 12.

The two sliding leaves 11 are controlled to move in order to simultaneously occupy their position of closing an opening 12 in which the two leaves cooperate to close the passage between the outer side E and the inner side I. Each sliding leaf 11 has an edge of lli closure coming to cooperate, in the closed position, with a closing edge lli forming part of the other sliding leaf. According to this example, each closing edge lli of a sliding leaf constitutes the closing amount for the other sliding leaf.

The two sliding leaves 11 are controlled to move in order to simultaneously occupy their open position in which they have returned to their respective housing 9. It should be noted that the door unit has an opening 12 equal to twice the width of that obtained when the door unit comprises a single sliding leaf 11. This opening 12 is delimited between a closing edge lli of a sliding leaf and the closing edge lli forming part of the other sliding leaf.

Of course, the closing edge lli of a sliding leaf and the closing amount with which it cooperates in the closed position are equipped with a system 13 for locking the sliding leaf 11 in its closed position. The locking system 13 can be made in any suitable way such as for example by an electromagnetic lock or a lock. Thus, in the example illustrated in FIGS. 1 to 5, the locking system 13 is produced on the closing edge lli of the sliding leaf and the closing upright 3 of the peripheral frame 2 while in the example illustrated in FIGS. 6 and 7, the locking system 13 is produced on the closing edges 11 of the sliding leaves.

The sliding leaf 11 is intended to be moved on demand between its position for closing the opening 12 and a position for opening the opening 12 for which the sliding leaf 11 enters the housing 9 to occupy its position opening. The sliding leaf 11 is moved in translation using a motorization, for example placed in the transom 5 of the peripheral frame 2. This sliding leaf 11 can be made of any material by being glazed, openwork or solid. In the example illustrated in the drawings, the sliding leaf 11 comprises a frame 11a supporting a window 11b which is fixed to the frame by glazing beads or frames 11c, located on the interior side I.

According to a characteristic of the invention, the protective screen 8 extends, in consideration of the sliding direction T, set back from the fixed side screen 7 so that when the sliding leaf 11 comes to occupy its position of opening, the sliding leaf 11 remains projecting relative to the protective screen 8, to delimit a safety space X to avoid crushing due to the offset between the glass 11b and the glazing bead 11c. In the example illustrated, the safety space X is taken between the opening edge 8i of the central frame 8b of the protective screen 8 and the glazing bead 11c of the sliding leaf, located closest to the closing edge lli of the sliding leaf 11. Typically, the safety space X is at least equal to 25 mm. Such an arrangement makes it possible to increase the reentry stroke of the sliding leaf 11 compared to the previous solutions, and consequently to release the sliding leaf 11 relative to the opening 12.

Advantageously, the protective screen 8 and the fixed lateral screen 7 are offset so that the difference in spacing D between their opening edges 8i, 7 _t taking into account the sliding direction T makes it possible to delimit the safety space X of 25 mm minimum. In other words, the opening edge 8i of the protective screen 8 is closer to the fixing upright 4 than the opening edge 7i of the fixed side screen by a spacing value D, by example greater than or equal to 30 mm to obtain safety space X.

Of course, to respect this difference in spacing D, the central frame 8b of the protective screen 8 has a width 11 which varies as a function of the width I of the central frame 7b of the fixed side screen 7.

According to an advantageous characteristic of embodiment, the fixed side screen 7 is positioned so that in the open position of the sliding leaf 11, the opening edge 7i of the fixed side screen 7 and the closing edge 11 _χ of the sliding leaf 11 substantially occupies a flush position. In other words, in the open position of the sliding leaf 11, the opening edge 7i of the fixed side screen 7 and the closing edge 11 of the sliding leaf 11 are situated substantially at the same distance from the fixing upright. 4. According to this advantageous position, the sliding leaf 11 is completely disengaged from the access passage defined between the opening edge 7i of the fixed side screen 7 and the closing amount 3 or between the two opening edges 7i fixed side screens 7.

To optimize the width L of the opening 12 relative to a total overall width of the access door according to the invention, it should be noted that each upright 3, 4 of the peripheral frame 2 has a limited width 12 included between 10 mm and 100 mm.

The invention is not limited to the examples described and shown since various modifications can be made without departing from its scope.
