Door handle rod with quick release

The present invention relates to a rod for a door handle and a door handle comprising such a rod.

A door conventionally comprises a frame on which is mounted a leaf comprising a lock provided with a follower crossed by a square orifice commonly called square.

The door comprises a door handle comprising a handle provided with a square-shaped housing, commonly called a handle square, intended to receive the end of a rod. Another part of the rod, more central, is inserted into the square of the lock follower.

Thus, the rotational movement of the handle is transmitted to the follower of the lock by means of the rod causing the actuation of a bolt of the lock.

To fix a rod on a handle, it is known to insert a screw into a hole provided in the handle and tighten the screw against the rod.

However, this manipulation is long and tedious, especially when the user has a multitude of rods to fix, knowing that he must perform this manipulation twice to fix the two handles of a door.

The object of the present invention is to remedy this drawback by proposing a rod for a door handle quickly fixing on a handle of a door handle.

To this end, the invention relates to a rod for a door handle comprising a handle provided with a housing intended to receive an end portion of the rod.

According to the invention, the end part of the rod comprises an automatic fixing means which deploys automatically inside the housing of the handle after its insertion into the latter in order to block the rod in the housing.

According to a variant, the automatic fixing means is deployed inside the housing of the handle so as to generate two opposing support forces F1, F2 inside the latter of which a first support force F1 exerted by the means of automatic fixing against a first surface of the housing and a second bearing force F2 exerted by an upper surface of the rod against a second surface of the housing opposite the first surface.

According to another variant, the automatic fixing means comprises a movable blocking element inside a housing formed in the rod between an unblocked position in which the blocking element is housed inside the housing and a locked position in which the locking element is partially outside the housing to exert pressure against the first surface of the handle housing.

According to another variant, the automatic fixing means comprises a compression means exerting a compressive force on the blocking element to keep it in abutment against the first surface of the housing of the handle.

According to another variant, the rod comprises a recess in which is housed the compression means. The compression means comprises a first end in abutment against a stop protruding from an internal surface of the blocking element and a second end in abutment against a rear wall of the recess.

According to another variant, the recess comprises a front wall opposite the rear wall. The front wall includes a counter stop for stopping the stop of the blocking element when the rod is not inserted in the housing of the handle.

According to another variant, the blocking element comprises a bearing surface bearing against the first surface of the housing when the blocking element is in the blocked position. The bearing surface comprises at least one notch for hanging the first surface of the housing.

According to another variant, the internal surface of the blocking element comprises a central surface portion inclined at an angle a) relative to the bearing surface of the blocking element. The housing of the rod is delimited by an external surface comprising a central surface portion inclined by the angle a) relative to the upper surface of the rod. The central surface portion of the blocking element is intended to slide along the central surface portion of the rod during the movement of the blocking element between the blocked position and the unlocked position in a direction A parallel to the upper surface of the rod and a direction B perpendicular to the upper surface of the rod.

According to another variant, the internal surface of the blocking element comprises a front surface portion and a rear surface portion parallel to each other and to direction A. The central surface portion is positioned between the front and rear surface portions .

The external surface delimiting the housing of the rod comprises a front surface portion and a rear surface portion parallel to each other and to direction A, the central surface portion being positioned between the front surface portion and the rear surface portion, the two front surface portions facing each other and the two rear surface portions facing each other, in the unlocked position.

According to another variant, the housing of the rod is delimited by a rear wall. The locking element comprises a rear end abutting against the rear wall in the unlocked position.

The rear surface portion and the central surface portion of the rod housing are connected by a first central wall. The rear surface portion and the central surface portion of the blocking element are connected by a second central wall. The second central wall abuts against the first central wall in the unlocked position.

The front surface portion and the central surface portion of the rod housing are connected by a first front wall. The front surface portion and the central surface portion of the blocking element are connected by a second front wall. The second front wall abuts against the first front wall in the unlocked position.

The invention thus provides a door handle rod that quickly attaches to a door handle handle.

The rod is fixed in the square hole of the handle automatically by inserting the rod in this hole.

The user no longer needs to perform an additional step of tightening a screw against the rod when using a rod of the prior art.

The invention also relates to a door handle comprising a handle provided with a housing.

According to the invention, the end part of the rod, as defined above, is inserted into the housing.

Alternatively, the door handle comprises an orifice positioned opposite the locking element to unlock the automatic fixing means.

This hole allows the user to insert a tool to quickly deactivate the mechanism. This allows the door assemblies to be dismantled from inside the room.

The invention applies to rods of different shapes and more particularly to rods of square section cooperating with handle housings of square section.

The characteristics of the invention will be described in more detail with reference to the accompanying non-limiting drawings in which:

Figure 1 schematically shows a rod fixed in a housing of a handle according to the invention;

Figure 2 schematically shows the rod and the handle mounted on a door;

Figure 3 shows the detail of the automatic fixing means when it is in the unlocked position;

FIG. 4 shows the detail of the automatic fixing means when it is in the locked position;

FIG. 5 shows the detail of a rod housing intended to receive a movable blocking element;

Figure 6 shows the bottom view of this housing;

Figure 7 shows the detail of the movable locking element;

FIG. 8 represents an orifice provided on the handle for unlocking the movable blocking element;

Figure 9 shows a handle hole according to another embodiment.

For the sake of clarity, identical or similar elements are identified by identical reference signs in all of the figures.

Figure 1 schematically shows a rod 1 fixed in an orifice 4 of a handle 3 according to the invention.

FIG. 2 schematically represents the rod 1 and the handle 3 mounted on a door 31.

In the examples of Figures 1 to 8, the rods 1 have an elongated shape with a square section and the handle housings have a square section.

Other shapes, such as hexagonal shapes are also possible.

The door 31 includes a mortise lock 32. It can be single or multi point.

The lock 32 comprises a follower 33 comprising a square orifice 34 intended to receive the rod 1 which also has a square section. This square orifice 34 is conventionally called the follower square.

The rod 1 comprises an end part 5 which is inserted into a housing 4 provided in a handle 3 of the door handle 2.

According to the invention, the end part 5 of the rod 1 comprises an automatic fixing means 6 which deploys automatically inside the housing 4 of the handle 3 after its insertion therein in order to block the rod 1 in the housing 4.

The automatic fastening means 6 is deployed inside the housing 4 of the handle 3 so as to generate two opposing support forces F1, F2 inside the latter of which a first support force F1 exerted by the automatic fixing means 6 against a first surface 7 of the housing 4 and a second bearing force F2 exerted by an upper surface 9 of the rod 1 against a second surface 8 of the housing 4 opposite to the first surface 7, as shown in the figure 1.

The automatic fixing means 6 comprises a blocking element 10 movable inside a housing 11 formed in the rod 1 between a non-locked position in which the blocking element 10 is housed inside the housing 11, as shown in FIG. 3, and a locked position in which the locking element 10 is partially outside the housing 11 to exert pressure against the first surface 7 of the housing 4 of the handle 3, as shown in FIGS. 1 and 4.

The dimensions of the rod 1 are slightly smaller than the dimensions of the housing 4 of the handle 3.

In the unlocked position, the rod 1 and the automatic fixing means 6 form a set of rectangular parallelepiped shape. The rod 1 comprises a lower surface 35.

The locking element 10 is retracted into the housing 11 of the rod 1 and does not protrude from the rod 1.

The locking element 10 comprises a bearing surface 16 which is an extension of the lower surface 35 of the rod 1.

In this way, the rod 1 having a smaller section than that of the housing 4 of the handle 3, it is possible to insert it into the latter.

The automatic fixing means 6 comprises a compression means 12 which is preferably a helical spring 12.

In the unlocked position, the spring 12 is compressed.

After the insertion of the rod 1 into the housing 4 of the handle 3, the automatic fixing means 6 automatically switches to the locked position, as shown in FIG. 4.

The rod 1 comprises a recess 13 in which the compression means 12 is housed.

The compression means 12 which was compressed expands in the recess 13.

The compression means 12 exerts a compression force on the blocking element 10 to keep it in abutment against the first surface 7 of the housing 4 of the handle 3.

The bearing surface 16 of the locking element 10 bears against the first surface 7 of the housing 4 of the handle 3.

When the compression means 12 expands in the recess 13, the blocking element 10 simultaneously performs a first translational movement in a direction A parallel to the lower 35 or upper 9 surface of the rod 1 and a second translational movement in a direction B perpendicular to these surfaces.

The locking element 10 partially protrudes from the housing 11 of the rod 1 and protrudes from the rod 1 both in the direction A and in the direction B.

In other words, the locking element 10 forms a protuberance relative to the lower surface 35 of the rod 1 in the direction B.

The locking element 10 thus occupies the space formed between the rod 1 and the housing 4 of the handle 3.

The pressure or the pressing force F1 exerted by the locking element 10 on the first surface 7 of the housing 4 of the handle 3 causes the displacement of the rod 1 in the direction B and a pressing of the upper surface 9 of the rod 1 against the second surface 8 of the housing 4.

Thanks to the automatic fixing means 6, the rod 1 is kept blocked between the first surface 7 and the second surface 8 of the housing 4.

The compression means 12 comprises a first end 17 in abutment against a stop 14 projecting from an internal surface 15 of the locking element 10 and a second end 18 in abutment against a rear wall 19 of the recess 13.

The stop 14 has an almost circular section.

The recess 13 comprises a front wall 20 opposite the rear wall 19.

The front wall 20 includes a counter stop 21 for stopping the stop of the blocking element 10 when the rod 1 is not inserted in the housing 4 of the handle 3 and preventing the stop 14 from coming out of the recess 13 of the rod 1 during the extension of the spring 12.

The counter stop 21 is formed by crimping.

According to one embodiment, the bearing surface 16 of the rod 1 comprises at least one notch 22 for hooking to the first surface 7 of the housing 4.

In the examples of FIGS. 1 to 4 and 7, the bearing surface 16 of the rod 1 comprises several notches 22.

The notches 22 are formed by alternating ribs 36, 37 and slots 38, 39, as shown in FIG. 7. The ribs 36, 37 include ribs of rectangular section 36 and ribs of triangular section 37. The slots 38 , 39 include slots of rectangular section 38 and slots of triangular section 39.

The locking element 10 is preferably made of polymer to improve the attachment.

The locking element 10 has a generally rectangular parallelepiped shape.

The internal surface 15 of the blocking element 10 comprises a central surface portion 25 inclined at an angle a) relative to the bearing surface 16 of the blocking element 10, as shown in FIG. 7.L angle a) is between 5 ° and 15 ° and is preferably about 9 °. In the example of Figures 1 to 7, the angle a) is 8.5 °.

The housing 11 of the rod 1 is delimited by an external surface 26 comprising a central surface portion 29 inclined by the angle a) relative to the upper surface 9 of the rod 1, as shown in FIG. 4.

As shown in FIGS. 3 and 4, the central surface portion 25 of the locking element 10 slides along the central surface portion 29 of the rod 1 during the movement of the locking element 10 between the locked position and the unlocked position.

The locking element 10 moves in two directions at the same time, the direction A parallel to the upper surface 9 of the rod 1 and the direction B perpendicular to the upper surface 9 of the rod 1.

In other words, the locking element 10 moves along the portion of the central surface 29 inclined by the angle a), called the slope a).

It is this inclination or slope which allows the translation of the blocking element 10 towards direction B perpendicular to the upper surface 9 of the rod 1 and therefore the blocking of the rod 1 in the housing 4 of the handle 3.

Under the effect of the spring 12, the locking element 10 moves along the slope and increases the external dimension of the rod 1. This evolution of the rib combined with the notches 22 made in the locking element 10 causes the clamping or blocking of the rod 1 in the housing 4 of the handle 3.

The central surface portion 25 supports the stop 14 of the locking element 10.

The internal surface 15 of the locking element 10 comprises a front surface portion 23 and a rear surface portion 24 parallel to each other and to the direction A.

The central surface portion 25 is positioned between the front 23 and rear 24 surface portions.

The external surface 26 delimiting the housing 11 of the rod 1 comprises a front surface portion 27 and a rear surface portion 28 parallel to each other and to the direction A. The central surface portion 29 is positioned between the front surface portion 27 and the rear surface portion 28. The two front surface portions 23, 27 are opposite one another and the two rear surface portions 24, 28 are opposite one relative to the other, in the unlocked position.

The front 27 and rear 28 surface portions are parallel to direction A.

In the unlocked position as shown in Figure 3, the locking element 10 is returned to the housing 11 of the rod 1. The spring 12 is compressed or retracted. The internal surface 15 of the locking element 10 conforms to the counterform formed on the external surface 26 of the rod 1.

The housing 11 of the rod 1 is delimited by a rear wall 41.

The locking element 10 comprises a rear end 40 which abuts against the rear wall 41 in the unlocked position and during the insertion of the rod 1 into the housing 4 of the handle 3.

The rear surface portion 28 and the central surface portion 29 of the housing 11 of the rod 1 are connected by a first central wall 42. The first central wall 42 forms a protuberance on the central surface portion 29.

The rear surface portion 24 and the central surface portion 25 of the locking element 10 are connected by a second central wall 43. The second central wall 43 forms a protuberance on the rear surface portion 24.

The second central wall 43 abuts against the first central wall 42 in the unlocked position and during the insertion of the rod 1 into the housing 4 of the handle 3.

The front surface portion 27 and the central surface portion 29 of the housing 11 of the rod 1 are connected by a first front wall 44. The first front wall 44 forms a protuberance on the front surface portion 27.

The front surface portion 23 and the central surface portion 25 of the locking element 10 are connected by a second front wall 45. The second front wall 45 forms a protrusion on the central surface portion 25.

The second front wall 45 abuts against the first front wall 44 in the unlocked position and during the insertion of the rod 1 into the housing 4 of the handle 3.

According to one possible embodiment, the door handle 2 comprises an orifice 30, 30 ′ positioned opposite the locking element 10 to unlock the automatic fixing means 6.

This orifice 30, 30 'makes it possible to deactivate the mechanism to make the door assemblies removable from inside the room.

According to one possible embodiment, the orifice 30 can be positioned on the underside of the handle 3, in front of notches 22 of the locking element 10, and aligned in the direction B, as shown in FIG. 8.

Alternatively, the orifice 30 'can be positioned in the axis of the housing 4 of the handle 3, as shown in FIG. 9. The orifice 30' is aligned in the direction A.

The installer is able to compress the spring 12 using a tool allowing the locking element 10 to be returned to the housing 11 formed in the rod 1 locking element 10 in the unlocked position. The goal is to have enough play to uncouple the rod 1 and the stand 2.
