Description:
RAIL MECHANISM FOR SLIDING DOOR

TECHNICAL FIELD

The present invention relates to a rail mechanism for providing opening and closing of sliding doors in vehicles.

PRIOR ART

Sliding doors are used in various vehicles like passenger vehicles and big vehicles like minibus, autobus. Sliding doors provide pluralities of advantages for users. The most important advantages are that sliding doors are more usable when compared with classical doors and they need less force and they can be used for long time.

In the known state of the art, the lower, intermediate and upper rails connected onto the body in sliding door systems have an inclined structure and this structure is not suitable for electrical opening-closing systems. In order to assemble said inclined rail to the vehicle, wide housing shall be provided in the vehicle body. Moreover, the bending process, applied for providing inclined structure to the rail, makes difficult providing dimensional sensitivity in the rail. In a sliding door system having inclined rail, said rail shall be designed particularly for each vehicle. In addition to these, in sliding door mechanisms having inclined structure, since the mechanism is free in the direction of Z and Y axes during the movement of the mechanism in the rail, an undesired movement freedom occurs for the door. Moreover, since the sliding door moves both in direction x and in direction y during closing while joining with wedges, it becomes difficult to engage the door to the wedge.

In the present art, in order to pass from manual version to electrical version in rail structures, an additional electrical motor kit is not sufficient and the system shall be completely changed. Another problem is that the sliding door system parts (for instance, bent rail) do not have the same geometry for the right door and for the left door and they cannot be used instead of each other. Due to the delimitations resulting from the joining of the sliding door to the vehicle, the door cannot freely realize the movements resulting from the effect of the inclination and the form of the rail. In the literature, there is the patent application with application number US2010199567 and with title“vehicle door opening / closing apparatus”. A vehicle door opening/closing apparatus includes a rail for a sliding door fixed to the outside of a vehicle cabin and extending along a front-back direction of the vehicle, a support member for supporting the sliding door and movable along the rail, first and second pulleys supported respectively to opposed longitudinal ends of the rail, a cable turned around by the first and second pulleys and retained to the support member. In said application, a structure is disclosed having inclined rail structure and comprising a drive system with motor in the rail mechanism.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a rail mechanism, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.

The object of the present invention is to provide easily opening and closing of the sliding door thanks to the option of operating the sliding door with electrical motor by means of the flat rail provided on the body.

Another object of the present invention is to provide easily opening and closing of the door thanks to the rail mechanism absorbing irregular movements occurring on the door due to the other rails provided in inclined structure on the vehicle and which function as guide during movement of the door.

Another object of the present invention is to eliminate usage of bent rail and to eliminate the bending process and the disadvantages resulting from this process. By means of this, dimensionally and geometrically more sensitive and more precise part is obtained.

Another object of the present invention is to eliminate the usage of bent rail and to eliminate the wide space requirement needed in the vehicle body for the bent rail.

Another object of the present invention is to facilitate production and assembly and to decrease part variety since the rail and mechanism parts, used on the right and left of the vehicle, can be used commonly. Another object of the present invention is to provide standard solutions, which can be applied simply like elongation and shortening of the rail, instead of developing separate system for each vehicle for the vehicles with sliding door which have a wide variety.

Another object of the present invention is to eliminate freedom of the lower mechanism in Z and Y axes and to delimit undesired door movements.

Another object of the present invention is to decrease movement in axis Y in the movement during engagement of the door to the wedges at the closing instant and to provide movement thereof substantially completely in axis X and to optimize the join with the wedge.

In order to realize all of the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention relates to a rail mechanism for providing opening and closing of sliding doors in vehicles and having a rail fixed onto the vehicle body and at least one roller positioned in said rail and which provides the door to advance between an opening position and a closing position. Accordingly, an arm is provided which is configured to connect to said roller from one end and to connect to at least one spherical housing part, provided on the door, by means of at least one spherical hinge from the other end. Thus, the sliding door absorbs irregular movements and can be opened and closed comfortably.

In a possible embodiment of the present invention, in order to provide folding of said arm during passage of the door from an opening position to a closing position, at least one primary arm and at least one secondary arm are provided which are connected to at least one intermediate hinge. Thus, the door can be opened at the maximum level and can pass to the closing position easily.

In a possible embodiment of the present invention, at least one guide arm is provided in order to delimit the movement direction of said primary arm and said secondary arm. Thus, the movement direction of the primary arm and of the secondary arm is delimited.

In a possible embodiment of the present invention, at least one command bracket is provided on the rail and the followings are provided on said command bracket:

at least one first guidance wall having a surface which widens towards the door opening direction in a manner moving the door away from the rail,

at least one second guidance wall having a surface which widens in the door closing direction in a manner providing approaching of the door to the rail by means of folding the arm, at least one first command roller which moves on said first guidance wall and which provides moving of the arm away from the body and which provides opening of the door and connected onto the primary arm,

at least one second command roller which moves on said second guidance wall and which provides folding of the arm and which provides closing of the door and connected onto the arm. Thus, the door is moved away from the rail and passes to the opening position and the arm is folded and the door approaches the body and thereby, the door passes to closed position.

In a possible embodiment of the present invention, said rail has a flat structure which extends in the direction of the width of the vehicle body. Thus, the sliding door can be easily opened and closed by means of electrical power.

In a possible embodiment of the present invention, said spherical hinge comprises:

a screw having a spherical head part in a manner placing to the spherical housing and whose end part passes through an assembly hole provided on the secondary arm,

at least one plastic heading positioned between the spherical housing and the spherical head part of said screw and which prevents friction,

at least one fixation element connected to the screw head part through the spherical housing and which provides connection of the spherical housing and the screw and which provides partial movement of the spherical housing,

at least one joining part connected to the end part of the screw in order to provide fixation of the screw passing through said assembly hole. Thus, the irregular movements, occurring on the door due to other rail mechanisms existing in inclined form on the vehicle and due to similar reasons, can be absorbed.

In a possible embodiment of the present invention, said spherical housing is provided on a door bracket connected onto the door.

In a possible embodiment of the present invention, in order to provide automatic opening and closing of the door, at least one band is provided which is connected to the roller and at least one motor is provided which provides movement to said band. Thus, the door can be opened and closed automatically.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter rail mechanism (100) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In Figure 1 , a representative perspective view of the assembled form of the subject matter rail mechanism (100) on the vehicle (1) body (2) is given. In said rail mechanism (100), there is a rail (10) connected onto the vehicle (1) body (2) and having a flat form. Inside said rail (10), at least one roller (11) is provided which provides advancing of the door (3) between an opening position (I) and a closing position (II). There is an arm (20) connected to said roller (11) from one end and connected to at least one spherical housing (41), provided on the door (3), from the other end by means of at least one spherical hinge (50).

In Figure 2, a top representative perspective view of the subject matter rail mechanism (100) is given. In order to provide folding of said arm (20), provided in the rail mechanism (100), during passage of the door (3) from an opening position (I) to a closing position (II), at least one primary arm (21) and at least one secondary arm (22) are provided which are connected by means of at least one intermediate hinge (24). In order to delimit the movement direction of said primary arm (21) and said secondary arm (22), there is at least one guide arm (25) connected to the roller (1 1) from one end and connected to the secondary arm (22) from the other end. Thanks to the guide arm (25), the intermediate hinge (24) can be opened such that the primary arm (21) and the secondary arm (22) can form an approximate plane and the rotation of the intermediate hinge (24) further when compared with this level is prevented.

In the rail mechanism (100), there is at least one command bracket (30) provided on the rail (10). As seen in Figure 2 and 3, in said command bracket (30); there is a second guidance wall (32) connected on the surface of the rail (10) facing the floor where the vehicle (1) is positioned and there is a first guidance wall (31) connected onto the other surface of the rail (10) which is parallel to the surface facing the floor. Said first guidance wall (31) has a surface which widens towards the door (3) opening direction in a manner moving the door (3) away from the rail (10). Said second guidance wall (32) has a surface which widens in the door (3) closing direction in order to provide approaching of the door (3) to the rail (10) by means of folding the arm (20). There is a first command roller (33) connected on the surface of the primary arm (21) in the alignment of said first guidance wall (31) and there is a second command roller (34) positioned on the surface of the primary arm (21) in the alignment of said second guidance wall (32). Said first command roller (33) contacts the inclined surface of said first guidance wall (31) and provides moving of the door (3) away from the body (2) and provides opening of the arm (20). When the door (3) passes to closing position, said second command roller (34) contacts the inclined surface of said second guidance wall (32) and provides folding movement of the arm (20) and provides approaching of the door (3) to the body (2).

In the rail mechanism (100), there is a secondary arm (22) connected to the primary arm (21) by means of an intermediate hinge (24) from one end and connected to a spherical housing (41), provided on a door bracket (40) connected onto the door (3), by means of a spherical hinge (50) from the other end. In Figure 6, a representative frontal view of said spherical hinge (50) is given. In the spherical hinge (50) structure; there is a screw (52) having a head part (521) in spherical form in a manner placing into said spherical housing (41) provided in the door bracket (40). An assembly hole (23), provided on the secondary arm (22), engages to an end part (522) of said screw (52). In order to provide fixation of said assembly hole (23) engaged to said end part (522) of the screw (52), at least one joining part (54) is connected to the end part (522) of the screw (52). In order to prevent friction between the spherical housing (41) and the head part (521) of the screw (52) placed into the spherical housing (41), there is a plastic heading (51) having spherical form. In order to provide connection of the spherical housing (41) and the screw (52) and in order to provide partial movement of the spherical housing (41), there is at least one fixation element (53) connected to the screw (52) head part (521) through the spherical housing (41). Since the spherical housing (41) can move partially on the head part (521) of the screw (52), the irregular movements occurring on the door (3) due to the other rail mechanisms (100), provided in inclined structure on the vehicle (1), can be absorbed.

In Figure 7, a representative perspective view of the form where the door (3) is completely open for the subject matter rail mechanism (100) is given. After the first command roller (33) contacts the first guidance wall (31) in the command bracket (30) and after the door (3) is moved away from the body (2) and after the primary arm (21) is opened in a manner forming an approximate plane with the secondary arm (22), the roller advances towards the end of the rail (10) in the door (3) opening direction. Thus, the door (3) completely passes to open position.

In a possible embodiment of the invention, in order to provide automatic opening and closing of the door (3), at least one motor (60) is provided in the rail mechanism (100). As can be seen in Figure 8, a motor (60) can be connected to the end part of the rail (10). Said motor (60) provides movement to at least one band (61). Said band (61) provides movement to the roller (1 1). Since the roller (1 1) moves automatically inside the rail (10) by means of the band (61), the door (3) can be automatically opened and closed.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
