Description

Child-safe sash system, furniture and method based on such a sash system

The invention relates to the field of opening systems, in particular for articles of furniture, more particularly for secure furniture vis-à-vis children. The system comprises one or more openings of the casement type. The invention relates more particularly to a bed for a child, in particular for a baby, comprising one or more secure openings.

In this field, it is known to propose securing means to prevent a child from opening the opening due to an associated danger. In the case of a bed, opening an opening forming a bed rail without supervision can cause a child to fall out of the bed.

The prior art offers key and lock systems which are complex and irrelevant when it is desired to quickly secure a closing of the opening and to open the opening quickly. In addition, a key and lock system involves a risk of key loss.

Patent FR 3 034 803 B1 offers a system for securing and opening quickly without the risk of losing the key. This system concerns a hinge system allowing a sash to be moved upwards to disengage it from a lower groove, and to be able to open the sash.

However, this system does not offer fully satisfactory security because opening it with force or body weight could allow a child to open the door, with an associated risk of accident.

Thus, an objective of the present invention is to propose an opening system allowing securing and rapid opening of the opening not requiring a key, and whose securing is improved compared to the prior art.

To achieve this objective, the invention proposes a child-safe opening system comprising a frame and an opening pivotally mounted on the frame between a closed position in which the opening is folded down on the frame and a position open in which the sash is pivoted to be partially at a distance from the frame, the sash being further configured to be translated at least along the pivot axis between a rest position and a translated position, the sash comprising a structure sash locking mechanism for pivoting locking of the sash in the closed position, the frame comprising a frame locking structure configured to cooperate with the sash locking structure to lock the sash in the closed position.

According to a first aspect, one of the sash and frame blocking structures is configured to be movable, relative to the sash or to the frame respectively, between a blocking position in which the sash blocking structures and frame cooperate together to lock the sash in the closed position, and a release position in which the sash and frame locking structures are uncoupled so as to allow both the translation and the pivoting of the sash towards the open position.

Advantageously, the invention involves, in addition to the translation of the opening, the unlocking of the blocking structures to allow the opening of the opening, which significantly increases the security of the opening system.

The invention further relates to a piece of furniture for children comprising an opening system according to the invention. Preferably, the piece of furniture is shaped like a bed, with two adjacent openings for the same frame.

Another object of the invention relates to a method for opening a sash of a system according to the invention, comprising a step of secure opening of the sash, and a step of secure closing of the sash.

The invention will be further detailed by the description of non-limiting embodiments, and on the basis of the appended figures illustrating variants of the invention, in which:

schematically illustrates a view in space of a secure opening system according to a preferred embodiment for a child's bed, the left opening being in the closed position and at rest;

schematically illustrates a view in space of the system of Figure 1 with said leaf in the closed and translated position;

schematically illustrates a sectional view of a system similar to that of the preceding figures with the leaf in the closed position and at rest, as well as a release position variant; And

schematically illustrates a view in space of hinges of an opening suitable for a system according to the invention.

The invention relates to a secure opening system 1, in particular for an article of furniture, more particularly for secure furniture vis-à-vis children. The preferred embodiment relates to a system with one or two wings (or opening 2) of a child's bed rail.

The system comprises a frame 3 and an opening 2 pivotally mounted on the frame 3. The reference 3a relates to a bed mattress. In Figures 1 and 2, a right opening (not shown) is completely open.

The opening 2 is configured to be able to be pivoted between an open position and a closed position. A pivot axis 4 is provided for this purpose, for example by means of a hinge 5. In the open position, the sash 2 is folded down on the frame so that at least one sash rim 6 is substantially aligned with at least one frame rim 7. In the open position, the sash 2 is pivoted to be partially at a distance from the frame 3, so that said sash rim 6 is not aligned with said frame rim 7 , and a portion of the opening 2 is remote from the frame 3.

The opening 2 is further configured to be translated at least along the pivot axis 4 between a rest position and a translated position. In the rest position, at least one section of the sash 2, in particular said sash rim 6, is close to a section of the frame 3, in particular said frame rim 7. In the translated position, said section sash (edge 6) is remote from said frame section (edge 7). In the context of the invention, the opening 2 can be closed and translated, while being considered closed.

According to a variant, the opening 2 is configured to be translated vertically upwards, the rest position being low, and the translated position being high. Thus, the weight of the sash 2 can be used to hold the sash in the rest position.

Patent FR 3 034 803 B1 proposes an arrangement of this type which can be used in the invention. Preferably, a pin 8 is arranged in a hinge structure with a greater travel for the hinge element 9 or hinge associated with the opening 2 compared to the usual hinges without this causing unhinging.

Alternatively, an additional tube 8a is added between the two hinges 9, 9a of two hinges 5 of an opening 2. In particular, the tube 8a connects the two hinges in order to close the space between two frames 9, 9a . Thus, said tube 8a fills the space and prevents finger jamming during the action of opening/closing the frames.

This tube 8a also makes it possible to reinforce the rigidity of the hinges in particular during the opening/closing action. The hinge can rest on the tube during the action to lift the mobile frame 9.

The invention proposes to improve the locking of the sash 2. Thus, the sash comprises a sash locking structure 10, and the frame comprises a frame locking structure 11. These structures can be understood as comprising each several different elements. They are configured to cooperate together to block at least one pivoting of the opening 2 when it is in the closed position.

In one aspect, one of the sash 10 and frame 11 blocking structures is configured to be movable between a blocking position and a release position. In the locking position, the sash 10 and frame 11 locking structures cooperate together to lock the sash 2 in the closed and rest position. Thus, the translation is also blocked. In the release position, the sash 10 and frame 11 locking structures are uncoupled so that the sash 2 can be translated to the translated position and then pivoted to the open position.

Advantageously, the invention involves, in addition to the translation of the opening 2, the unlocking of the blocking structures to allow the opening of the opening 2, which significantly increases the security of the opening system 1. In addition, the The invention makes it possible to perform two actions, unlocking and translation, before being able to open the opening.

Preferably only one of said locking structures is movable between said locking and releasing positions. The preferred layout is detailed below. This makes it possible to use one hand for translation and another hand for unlocking concomitantly with translation.

According to a variant, the sash locking structure 10 comprises a primary male structure 12 and the frame locking structure 11 comprises a primary female structure 13 cooperating with the sash locking structure. In particular, the primary female structure 13 comprises at least one hole in the frame 3, and the primary male structure 12 comprises a blocking arm configured to be inserted into a first hole 13a to block the opening 2. Advantageously , this makes it possible to have structures with good rigidity during locking compared to a rail along an edge of the frame and a groove along a corresponding opening edge. The sash 2 can thus be held securely in the closed position despite a force applied by a child on the sash. In the example illustrated, these primary structures 12, 13 are immobile in themselves, but the primary male structure 12 being carried by the opening 2 is moved with the opening 2.

According to a variant, the opening locking structure 10 comprises a secondary female structure 14, preferably arranged on the primary male structure 12, and the frame locking structure 11 comprises a secondary male structure 15, preferably arranged at least partially in the primary female structure 13, in particular a second hole 13b. The secondary male structure 15 cooperates with said opening blocking structure, in particular secondary female structure 14 of the primary male structure 12. Preferably, one or the male structure, in the example the secondary male structure 15, is movable between locking and releasing positions. Advantageously, the secondary blocking structures 14, 15 block both the pivoting and the translation of the opening 2 to further secure the system 1.

In the example illustrated, the secondary male structure 15 is thus movable. In addition, the secondary female structure 14 is immobile in itself, but being carried by the opening 2 is moved with the opening 2.

In particular, the blocking arm (12) comprises a concave blocking relief (14), and the hole 13b is equipped with a blocking pin (15) configured to be inserted into the concave relief (14) to block the opening 2, in particular to block the primary male structure 12 in the primary female structure 13.

According to a variant, the system further comprises a return means 16 for the male structure, namely the secondary male structure 15 in the variant illustrated, holding it in the locking position, and a release means 17 for moving said male structure ( 15) to the release position.

Preferably, the blocking finger (15) forms part of a blocking device 18 with a spring (16) holding the blocking finger (15) in the blocking position and a gripping element (17) for pulling the finger lock (15) to the release position. The release means 17 can be a ring or a pull hook to unlock the opening 2. In Figure 3, the secondary male structure 15 is in the release position. The reference 17a relates to an example of the position of the release means 17 when the secondary male structure 15 is in the locking position.

Preferably the primary male structure 12, in particular the locking arm, comprises a cam surface 19 for example of the beveled type. This cam surface 19 is configured to cause the secondary male structure 15, in particular the locking finger, to slide in opposition to the return means 16, until the secondary male structure 15 is opposite the secondary female structure 14 , and thus perform locking without actuating the frame locking structure 11.

The invention further relates to a piece of furniture, in particular a piece of furniture for children comprising at least one opening system 1 as described previously. In the illustrated variant, it is a child's bed comprising two adjacent openings 2 for the same frame 3.

The invention also relates to a method for opening and/or closing sash 2 of a sash system 1 as described previously, comprising a step of secure opening of sash 2, and/or a step secure closing of the sash 2.

For the illustration, the opening 1 may initially be in the closed position and at rest. The return means 16 blocks the male structure, in particular the secondary male structure 15, so that the opening 2 is blocked in the closed position.

A user then moves said male structure (15) in particular by pulling the release means 17, for example as illustrated in FIG. 3. Thus, said male structure (15) is therefore uncoupled from the corresponding female structure, in particular the female structure secondary 14. It is then possible to lift the opening 2 towards the translated position.

Once the sash 2 has been completely lifted, it is then possible to pivot it towards the open position, in particular a translated open position, then an open position at rest.

The same operations are repeated in reverse to close sash 2 and block it.

In the preferred variant, when closing, it is not necessary to actuate the release means 17 due to the beveled shape (19) and the return means 16.
