Abstract
Description
Title of the invention: Locking system for railway wagon doors. Technical field
[0001] The present invention relates to a locking system for a railway wagon door or floating boat cabin (e.g., a cruise ship cabin), comprising a floor-mounted module consisting of a cylinder housing a sliding stud between a retracted position and an extended position, and a bottom door module comprising a support. Previous technique
[0002] In the field of rail transport, various solutions have been developed to manage the opening and closing of wagon doors, particularly compartment doors and doors separating different areas within the same wagon. In some cases, the doors must be kept closed. This is easily achieved using door handles and locks. In other cases, the doors must be kept open. Hooks are commonly used to secure an open door to an adjacent wall. Swivel feet, which can be positioned as needed, are also used to hold the door open by resting it on the floor. These systems are relatively simple and sufficient to keep a door open despite the numerous stresses typical of rail transport, namely vibrations and shocks, which can sometimes be quite violent.
[0003] However, these conventional means, although effective in terms of mechanical support, require manual placement either by an agent or by a passenger.
[0004] To overcome these various drawbacks, the invention provides various technical means. Summary of the invention
[0005] First of all, a first objective of the invention is to provide a system to ensure that a railway wagon door remains in an open position despite the stresses of vibration and shocks caused by the movement of the wagon.
[0006] Another objective of the invention is to provide a holding system that operates in a fully automatic manner.
[0007] Another objective of the invention is to provide a holding system to ensure total clearance of the passage from any obstacle on the ground when the door is not in the holding position.
[0008] Yet another objective of the invention is to adapt the holding force according to the constraints of architecture and use.
[0009] Yet another objective of the invention is not to affect the aesthetic appearance of the place where the system is installed, not to impact or degrade the aesthetics of the place of use.
[0010] To this end, the invention provides a locking system for a railway wagon door or floating boat cabin, comprising a floor-mounted module consisting of a sleeve housing a sliding stud between a retracted position and an extended position, and a bottom door module comprising a support, the support comprising a permanent door magnet, the sliding stud comprising one or more permanent floor magnets, and the magnetic force of all the magnets being calibrated so that, when all the magnets are aligned, putting the sliding stud into the extended position ensures that the door is held against the bottom door module in this position of alignment of the magnets.
[0011] This system allows a door to be held in the open position simply, without any intervention or manipulation by an employee or passenger. The system is modular and adaptable to both the architecture and the particularly demanding operating constraints of railway carriages.
[0012] According to an advantageous embodiment, the sliding block is removable. This arrangement allows the block to be removed either to adjust the number of magnets according to requirements, and / or for maintenance purposes.
[0013] According to another advantageous embodiment, the floor magnets are mounted removably and in an adjustable number within an internal cavity of the sliding block. The designated space allows for easy addition or removal of one or more magnets. Depending on the context and constraints, the number of magnets is adjusted to ensure secure door retention.
[0014] Advantageously, the sliding block is made of magnetic material.
[0015] Also advantageously, the sleeve is made of a non-magnetic material. For example, an aluminum alloy is used. This arrangement allows the sliding block to move axially within the sleeve without being affected by the magnetic effect of the magnets.
[0016] Advantageously, the force required to release the door from the open holding position is greater than 3.3 Kg. Brief description of the drawings
[0017] All implementation details are given in the following description, supplemented by Figures 1 to 3, presented solely for the purpose of non-limiting examples, and in which: Fig. 1
[0018] [Fig.1] [Fig.1] is a schematic cross-section of an example of an embodiment of a locking system; Fig. 2
[0019] [Fig.2] [Fig.2] shows the locking system of [Fig.1] before connecting the magnets; Fig.3
[0020] [Fig.3] [Fig.3] shows the locking system of [Fig.1] once the magnets aligned. Description of the implementation methods
[0021] Figures 1 to 3 illustrate an example of a locking system 1 for a door 10 of a railway wagon or floating craft cabin, such as for example a passenger ship cabin.
[0022] The system comprises two complementary parts, one being a recessed module 2 intended for fixed floor mounting, and the other being a bottom door module 6 10 intended for fixing against a door, and therefore mobile with that same door.
[0023] The fixed part is adapted for embedding at ground level, for example in the floor of a railway wagon compartment, in the area allowing the door to be opened.
[0024] The floor-mounted module 2 11 consists of a sleeve 3 or cylinder housing a sliding stud 4 movable between a retracted position, in alignment with the floor surface, and an extended position, to approach in the immediate vicinity of a magnet 8 provided on the door module, as described later.
[0025] The sliding pad 4 has an internal housing 12 designed to hold one or more permanent floor magnets 5. In the illustrated example, the magnets can be mounted in series. To adapt the number of magnets to the context, the sliding pad 4 is removable, and the floor magnets 5 are mounted in an adjustable number and in a removable manner within this internal cavity 12. The sliding pad is made of magnetic material. The sleeve 3 is made of non-magnetic material (preferably aluminum alloy). The removable arrangement of the sliding pad also facilitates maintenance of the internal parts of the recessed module. Alternatively, the upper surface of the removable pad 4 is provided for a finish suitable for the installation site or is polished. This ensures that the aesthetic appearance of the location is not affected. where the system is installed, or not to impact or degrade the aesthetics of the place of use.
[0026] The bottom door module 6 includes a support 7 for fixing against the bottom of the door 10 to be held. It is equipped with a permanent door magnet 8. It also includes a support block 9, arranged under the support 7 and designed to limit the door's travel by bearing against the sliding pin 4 when it is in the extended position, attracted by the magnet 8 of the support 7.
[0027] The magnetic force of the set of magnets 5, 8 is calibrated to ensure that, when all the magnets are aligned, the sliding block 4 is moved into the extended position. This alignment of the magnets ensures that the door 10 is held against the support block 9 of the bottom door module 6.
[0028] Of course, the user (a passenger in the carriage compartment) or an agent can close the door at any time. It is then sufficient to exert a restoring force on the door greater than the holding force provided by the aligned magnets.
[0029] The locking system as described allows the holding force to be easily and quickly adapted according to the constraints of architecture and use, such as the dimensions and weight of the door, the lateral position on the door of the bottom door module, the intensity and frequency of vibrations and shocks, etc.
[0030] In one embodiment, the force required to release the door from the open holding position is greater than 3.3 kg. In other words, in this example, the force of the permanent magnets is 11 kg of adhesion and 2.1 kg of shear force. List of reference signs
