Description

The present invention relates to a plug for the suspension of leaves such as doors, windows, etc., comprising a hinge intended to be fixed on a frame of a female part intended to be fixed on a leaf and to collaborate with the hinge pin.

This type of plug (FIG. 1) comprising a hinge 1, fixed to the frame D has a threaded rod 3 or other means, and a female part 4, fixed by a threaded rod 5, or other means to the leaf V, are known. and appreciated for the simplicity of the installation of the leaf. They have the drawback, especially when the leaf does not rotate around a vertical axis, for example for windows tilting around a horizontal axis, that following an untimely movement of the leaf the female parts leave the studs 2 hinges and the leaf is no longer supported. On the other hand, insulating glass, double glazing weighs down the leaves and the suspension by these sheets lacks solidity.

To overcome these drawbacks, plugs have been developed and used comprising (FIG. 2) three female parts 6, 7, 8 and a pin 9. The two female parts 6, 7 are fixed to the frame D leaving a space between them equal to the length of the third female part 8 which is fixed on the leaf V. To support the leaf, the third female part 8 is introduced into the space left between the female parts 6, 7 fixed on the frame D and after alignment on ensures the assembly by introducing the pin 9 whose length is such that it crosses the three female parts 6, 7, 8. This assembly does not have the disadvantage of an untimely detachment, unless the pin 9 is removed, which hardly happens involuntarily. In addition, for the suspension of a leaf at least two of these sheets are used, the length of the edge of the leaf and of the frame adjacent to the axis of rotation of the leaf and the untimely and simultaneous exit of two pins is unlikely. The use of these plugs with three female parts has the drawback that it is difficult for a single person to suspend the leaf V because he must, on the one hand, insert the female parts 8 fixed on the leaf V between the parts females fixed 6, 7 on the frame D align them and insert the pins 9. It is practically necessary to have two people to hang and hang a leaf. Often the doors and windows as well as the sleeping frames are manufactured at the factory and are then brought to the site so that the sleeping frames are fixed in their final place. During the production of window frames and windows at the factory, transportation to the site, setting up to apply paint, etc., each leaf is hung and hung several times and if the three-piece female plugs are used (Figure 2) the time required for this work is longer and as mentioned above, two people are often used. On the other hand, the use of these sheets ensures greater solidity, in particular for heavy leaves.

The present invention aims to overcome these drawbacks and proposes a sheet presenting the advantages of the two sheets described above while eliminating their drawbacks.

The card according to the invention is characterized by the characterizing clause of claim 1.

The advantages of this sheet are as follows: after having fixed the various parts in their final position, the locking part is put in a passive state thus allowing the leaves to hang and depend without any difficulty since there are in fact sheets like that of Figure 1. When the preliminary work is finished, the locking part is put in active state which prevents the female part fixed on the leaf from moving linearly so the unhooking of the leaf is prevented. In addition, the leaf suspension is safer and more solid as seen above.

A preferred embodiment described in claim 2 makes it possible to block the locking part in the active state in order to avoid its untimely passage into the passive state and also strengthening the holding of the leaf.

The advantages of this variant are as follows: After having fixed the hinge and the female parts in their final positions, the spindle is set aside and the second female part is placed in passive state, thus the hinge fixed on the frame and the female part fixed on the leaf allow the leaf to hang and hang very easily, at the factory, during transport, during installation on site during painting work etc. The second female part is not put into active state and the spindle is only placed when the leaf must no longer be depended, at least for a long period. Indeed, the hinge pin engaging in the eye of the female part fixed on the leaf is sufficient to support the leaf and this mon tage actually corresponds to the type of sheet illustrated in Figure 1 which has been used for a long time. Once the preliminary works are finished and to avoid the untimely exit of the female part fixed on the hinge leaf, the second female part is put in active state which prevents the linear displacement of the first female part and therefore the leaves and we block at this position by the spindle.

According to another embodiment, the second female part is formed of a removable socket having at least the length of the stud and of a socket integral with the element for fixing to the frame. When the female part is in a passive state, the spindle and the removable socket are removed, thus leaving sufficient travel between the two female parts to hang and hang the leaf. In active state, insert the removable socket between the fixed socket of the second female part and the first female part and which prevents the linear displacement of the first female part and assemble the assembly by the pin which is introduced through the eye of the second female part, that is to say the socket integral with the fastening element of the second female part. From this moment, the leaf cannot be depended because the sleeve (s) prevent the untimely or voluntary movement of the female part fixed on the leaf and the sleeve is prevented from moving laterally because it is held by the spindle. A single card according to the invention is sufficient to ensure that the leaf will not be inadvertently depended, the other cards may be like that of FIG. 1. However, for reasons of uniformity and aesthetics, it is possible to use only cards according to the invention.

According to another embodiment and in order to reinforce the holding of the leaf relative to its axis of rotation, it is possible, following the second female part, to attach a third female part to the leaf so that when the spindle passes through the second and third female part allows to strengthen the holding of the leaf in the direction perpendicular to the axis of rotation.

According to another embodiment, one or more sockets, the length of which is equal to that of the first socket, can be arranged after the fourth female part, is one or two female parts fixed respectively to the frame and the leaf and the spindle. crosses all the sockets and female parts thus creating a hinge.

According to yet another embodiment, the second female part is formed of an at least approximately cylindrical part integral with the fixing means on the frame and arranged to allow the female part to pivot at least 45 ° around an axis perpendicular to the axis of the cylindrical element, the pivoting allowing the female part to pass from the active state to the passive state and vice versa. According to one embodiment, the second female part, the fixing means comprise a threaded rod fixed near the end of the cylindrical element opposite the end adjacent to the first female part. By rotating the female part around the threaded rod by at least 45 °, you go from the active state to the passive state and vice versa.

According to a preferred embodiment, the first female part comprises on the side adjacent to the second female part a thread and the spindle has a corresponding thread and a shoulder ensuring its locking by ser rage thus avoiding its untimely distance during the rotation of the leaf.

According to another embodiment, the fixing means consist of a plate provided with a pivoting screw operates around this screw.

The embodiment according to the invention shown in Figure 3, includes a hinge 10, a first female part 13, a socket 16, a second female part 17, constituting the locking part, comprising a removable socket 17 ′ and a fixed socket 17˝ and a spindle 20. The hinge 10 is fixed to the frame D by a threaded rod 11, the first female part 13 is fixed to the leaf V by a threaded rod 14, the fixed socket 17 ′ of the female part 16 will be fixed to the frame by a threaded rod 18 at an adequate distance (Figure 2) from the hinge 10. When assembling this plug, the eye 15 of the female part 13 engages the stud 12 of the hinge 10 and the pin 20 engages through the eye 19 of the fixed socket 17˝ to the removable socket 17 ′, when all the parts are in their final place.

In Figure 4, there is shown the exact relative positions of the hinge 10 and two female parts 13 and 16 the part 16 being in passive state.

During the preliminary works, as mentioned previously, the leaf V is suspended and supported only by engaging the eye 15 of the female part 13 around the stud 12 of the hinge 10. The space left between the end of the stud and the end lower of the female part 16 fixed on the frame D is at least equal to the length of the studs 12 fixed on the leaf V so that the leaf V can be hooked and unhook by moving in this space. When we want to permanently fix the leaf V, we introduce the removable bushing 17 ′ between the two female parts 13 and 16 and we assure the assembly by the pin 20 which we insert through the eye 19 of the fixed bushing 17˝. The length of the socket 17 ′ is equal to the length of the space between the female part 13 and the fixed socket 17˝ and the length of the pin 20 is such that it engages at least partially in the female part 13 After the fitting of the socket 17 ′ and of the pin 20, the leaf can no longer be unhooked because any movement parallel to the axis of rotation of the plug is prevented by the removable socket 17 ′.

With the assembly thus completed, there is a plug close to the plug in FIG. 2. When we want to unhook the leaf, we remove the pin 20, and the removable socket 17 ′ and we can unhook the leaf V.

Instead of a single socket, we can use several whose sum of lengths can fill the space between the two female parts. The hinge and female parts 13 and 16 can be fixed by means of wings provided with holes for the passage of screws or even nails.

In Figure 5, there is shown another embodiment of the invention, the difference from the first is the presence of a third female part 21 fixed to the leaf V by a threaded rod 22. The other parts of this sheet identical to those of FIG. 3 and 4 have been referenced by the same numbers followed by a. The advantage of this sheet is that after the installation of the pin 20a in the two female parts 21, 16a the leaf is held perpendicular to the axis of rotation by the female part 21 also which increases the safety of the assembly.

According to another embodiment, following the female part 21, it is possible to place a new socket and finish with one or two new female parts fixed respectively on the frame D and the leaf V thus forming after the installation of the spindle a long hinge whose interest is the solidity of the assembly. However, if good hold is desired, it is more advisable to use several plugs of the type with two or three female parts (Figures 4 and 5).

The plug shown in Figures 6 and 7 includes: a hinge 30 whose stud 31 has a cylindrical housing 32 and it is fixed to the frame D by a threaded rod. The female part 34 is fixed by a threaded rod 35 on the leaf V and its eye 36 at least partially engages the stud 31. A second female part 37, constituting the locking part and comprising a socket 39 is fixed by a threaded rod 38 on the frame D. The threaded rod 38 is fixed to the end of the socket 39 of the female part 37, not adjacent to the female part 34. The socket 39 has two opposite radial holes 39a, 39b. In this position which is the active state of the second female part 37, the leaf V cannot be released because the female part 34 which is integral with it cannot move linearly to leave the stud 31. To block the assembly in this position, the pin 40 is inserted into the socket 39 of the second female part 34 and it comes to be coupled by a part cy lindrique 41 in the housing 32 of the stud 31. When it is desired to hang the leaf, the pin 40 is removed, the cylindrical seat 41 is introduced into one of the radial holes 39a or 39b and the sleeve 39 is pivoted around the threaded rod 38 of 90 ° (Figure 7) thus putting the female part 37 in a passive state and at the same time allowing the linear displacement of the first female part 34 which can leave the stud 31. The distance d between the first female part 34 and the second female part 37 in passive state being at least equal to the length of the stud 31. Of course, the pivoting of the second female part can be done by hand or by means of pliers, etc. During the preliminary work, we use the plug in the state shown in Figure 7 and when we want to avoid the hanging of the leaf, we rotate the second female part 37 in the active state (Figure 6) and we block the assembly by the introduction of the pin 40. However, it is possible not to introduce the pin 40 the assembly will be locked, but the part 37 will not be blocked.

To prevent the rod 38 from rotating in the wood of the frame each time the second female part is moved from the active state to the passive state and vice versa, which will weaken the holding of the threaded rod 38 by deformation of the wood, it is possible to envisage screwing the socket 37 into the threaded rod by another threaded rod of dimensions smaller than those of the rod 38 which would thus be provided with an internal housing with a tapping.

In Figure 6a there is shown an alternative embodiment of that shown in Figures 6 and 7. The pin 400 has a thread 401 and a shoulder 402 and it is screwed into a tapping 360 of the first female part 340. The shoulder 402 makes it possible to block the spindle 400 by screwing and to avoid its unscrewing during the rotation of the leaf. The pin 400 has a hexagonal hole 403 or a head allowing its screwing - unscrewing. In this case, in order to be able to turn the second female part 37 (FIG. 6), a hexagonal hole is provided in the extension of the axis of the rod 38, the rotation being effected by means of a key.

In Figures 8 and 9, there is shown a fourth embodiment similar to the previous except that the fixing of different parts of the plug on the frame and the leaf is made by means of plates and screws.

The plug of Figure 8 includes a hinge 41 secured to a plate 44 provided with two holes for the passage of the fixing screws on the frame. A female part 43, constituting the locking part secured to a second plate 47 provided with a hole 48 for the passage of a fixing screw on the frame. On the leaf will be fixed by means of a plate 49 provided with two holes 50, 51 for the passage of two fixing screws a female part 52. The assembly will be locked by a pin 53 when the female part 52 secured to the leaf engages the stud 42. To allow the leaf to hang down and hang down, the female part 43 is pivoted around its point of attachment to the frame (FIG. 9) which is the hole 48, to bring this female part into the passive state leaving a clearance between the hinge and the pivot point allowing the leaf to hang and hang by means of the female part 52 (FIG. 1).

When the preliminary work is finished, we do pivot the part 43 in the active state (FIG. 8) and the assembly is locked by the pin 53. It is also possible to give up the spindle but in this case the locking part is not blocked and the leaf is not as well suspended only if the spindle was in place.

As mentioned previously, a single card according to the invention makes it possible to prevent untimely detachment of the leaf nevertheless, for reasons of uniformity, it is possible to use only cards according to the invention, each leaf having, in principle, at least minus two of these sheets, which also strengthens the strength of the assembly.
