Description

ARRANGEMENT FOR MOUNTING A CARDAN SEAL FOR CONNECTING THE BARREL OF A LATCH TO A LOCK

The invention relates to an arrangement for mounting a universal joint for connecting the barrel of a lock to a lock, in particular to a side door of a motor vehicle.

The barrel of a lock can be connected to the output of a lock by a universal joint engaging with this lock output. This output corresponds to the outer locking lever of the lock. But the relative position of the lock and the lock may vary depending on the vehicle. As a result, arrangements specific to each vehicle are to be made because, for a correct transmission of the rotary movement, this universal joint can not be too long and can not be subjected to large angular deformations. Indeed it enjoys an angular freedom that only absorbs a few millimeters of offset caused by dispersions of different parts of the system.

It can therefore be envisaged to design the lock so that it presents its output in a suitable location for the connection of the universal joint. However, this entails making a lock specific to each positioning, which is heavy design and manufacturing.

The invention solves this problem by proposing a mounting arrangement of a connection member, in particular a cardan joint, a lock on a standard lock, which adapts to the relative positioning of the lock output and associated lock barrel. To do this, the invention proposes an arrangement for mounting a connection member of the barrel of a lock on a connection output of a lock, corresponding to said connection member, characterized in that it consists of a module having a connection input at the lock output, said input device, a device for transmitting the displacement of said input device and a connection output device corresponding to said latch connection member, said output device, said device of transmission being designed to be of a length adapted to the adequate relative positioning of said output device and the lock cylinder.

According to a preferred embodiment, said transmission device comprises an eccentric link connected to a radial lever of said input device.

Optionally or additionally, said transmission device may comprise a gear connected to said output device.

Advantageously, said transmission device is housed in a housing. And preferably, said housing comprises a device for mechanical connection to the lock.

Said connecting device may be a snap-in slide. Optionally, any other mechanical connection means can be used, such as pinning, screwing, welding, etc. Preferably, the mounting arrangement comprises a sealing cap provided with a cardan guiding cone of said connecting member. Preferably, said connecting member is a universal joint. The invention also relates to a lock for receiving a mounting arrangement, as described above, characterized in that it comprises a mechanical connection arrangement of this arrangement. Said connection arrangement may be a snap-in rail. The lock may comprise a sealing cover provided with a guide cone of the gimbal of the connection cable.

Figure 1A is a front view of a lock according to the invention.

This lock 1 is of standard design and comprises, in conventional manner, an output 2 corresponding to its external locking lever and intended to be connected to the barrel of a lock by means of a universal joint engaging with this lock exit. The lock 1 comprises a mechanical connection arrangement of a mounting arrangement according to the invention and which will be described later, preferably a snap-fitting rail 3. When the lock can be connected to the lock cylinder, as such, that is to say, when the relative positioning of the lock output 2 and the lock cylinder is adequate for a direct universal joint connection, the lock 1 is equipped with a sealing cover 4 provided with a 4A guide cone of the connecting universal joint, as shown in Figure 1 B. This cover 4, preferably plastic, just cap the lock at the location of the outlet 2 and prevents any introduction of water and dust to inside the lock. Its conical portion allows self centering the universal joint in the lock during assembly of the barrel.

When the relative positioning of the lock output 2 and the lock barrel is not adequate for a direct universal joint connection of the barrel of a lock, a mounting arrangement of the connecting universal joint is provided in accordance with the 'invention.

A first variant of this mounting arrangement mounted on the lock 1 is shown in FIG. 2A.

It consists of a module 5 having a device for connection to the output 2 lock, gimbal type, said input device, a device for transmitting the rotary displacement of the input device and a connection output device 6 corresponding to the universal joint of the lock connection cable, said output device.

The transmission device is designed to be of a length adapted to the appropriate relative positioning of the output device 6 and the lock cylinder. This module 5 is of a first length.

This module 5 is equipped with a sealing cap 7 provided with a guide cone 7A of the universal joint of the connecting cable, as shown in FIG. 2B. This sealing cap 7, preferably made of plastic, caps the module at the location of the outlet device 6 and prevents any introduction of water and dust inside the module and the lock.

A second variant of the mounting arrangement mounted on the lock 1 is shown in FIGS. 3A to 3C.

It consists of a module 8 having a device for connection to the lock output 2, of the cardan head type, said input device, a device for transmitting the rotary displacement of the input device and a link output device. 9 corresponding to the universal joint of the lock connection cable, said output device. In FIG. 3A, such a universal joint C for connecting the barrel of a lock is shown mounted on the arrangement. The transmission device is designed to be of a length adapted to the appropriate relative positioning of the output device 6 and the barrel lock. This module 8 is of a second length, greater than the first length of the previous module 5.

This module 8 is equipped with a sealing hood 10 provided with a guide cone 10A of the connecting universal joint. This sealing cap 10, preferably made of plastic, caps the module at the location of the outlet device 9 and prevents any introduction of water and dust inside the module and the lock.

As can be seen in FIG. 4A, the module 8 comprises a housing provided with a device for mechanical connection to the lock, preferably a snap-on slide 11 intended to fit and snap into the rail 3 of the lock, as shown in Figure 4B.

During this assembly, the input device of the module 12 is disposed in the output 2 of the lock.

In addition to their length and therefore their transmission device which are different, all the modules 5, 8 are identical, with respect to the characteristics that have already been described.

The transmission device of the module will now be described, with reference to FIGS. 5A and 5B.

In these figures is shown the transmission device of the module 8 of the second variant, of great length.

This transmission device comprises two subsets for transmitting the rotary displacement of the input device 12 of the module.

The first transmission subassembly comprises an eccentric link 13 connected to a radial lever 12A of the input device 12 and to a radial lever 14A of an intermediate rotary disc 14.

The second transmission subassembly comprises a gear 15 engaged with this intermediate disk 14 toothed and the output device 9 also toothed.

Housed in its housing 8A, this module 8 is shown in FIG. 5B secured to the lock 1. The combination of these two transmission subassemblies makes it possible to achieve a transmission of relatively great length and small relative thickness and width, which is desirable for the purpose of space.

Turning now to module 5 of the first variant of smaller length, its transmission device is preferably composed of said first subassembly only, namely an eccentric link 13 connected to a radial lever 12A of the device. 12 and a radial lever, such as the lever 14A, the output device 6 of the module.

Figures 6 to 8 are detail views of previous figures. In Figure 6, there is shown the module 8 with its housing provided with a mechanical connection device to the lock, preferably a snap-in slide 11 intended to fit and snap into the rail 3 of the lock. During this assembly, the input device of the module 12 is disposed in the output 2 of the lock, visible in Figure 7. Around this outlet 2, is arranged on the lock 1 a shoulder 16 provided with a peripheral groove. sealing 16A. On the module is provided a corresponding flange 17. This flange 17 is slotted on its thickness to facilitate its mounting and comprises a rib 17A intended to fit in the groove 16A of the shoulder 16 of the lock, as shown in Figure 8. The invention is obviously not limited to the two module variants nor to the two embodiments of the transmission device described.

As described, the invention allows the mounting of a lock and a lock in three different relative positions: when this positioning is close, the lock is equipped as shown in Figure 1 B and connected directly to the cylinder of the lock by means of a universal joint, when the distance between lock and lock is intermediate, a module 5 of the first variant is used, for this connection by universal joint, when the distance between lock and lock is greater, about ten centimeters, a module 8 of the second variant is used for this connection by universal joint. However, any module of any length can be used according to the invention, to ensure the mounting of the cardan joint connection of the barrel of a lock on a link output of a lock, rods and gears that can be used alone or associated to realize the transmission device of the module. Although described only in the context of a universal joint lock and lock connection, the invention applies to any connection member of a lock and a lock, for example a threshing device, a rod or to connecting cable. Indeed, if the installation constraints may be less with such connecting members, they exist however. The invention solves the problem of their assembly regardless of the relative positioning of the lock and the lock.
