Description

The invention relates to a device for fixing objects on a rail, in particular of vehicle seats in a transport vehicle, wherein in the rail is a longitudinally extending groove and the object is associated by means of a lever releasable clamping device and this an adjusting device and clamping device and adjusting device together form a unit which is fixed to the rail strip and surrounded by a common housing.

STATE OF THE ART

In many areas of daily life, it is necessary to set items, the position may need to be adjusted beforehand. The present invention relates to all possible applications, but is preferably used in the definition of vehicle seats. But this should not be limiting.

Vehicle seats in conventional cars are set to short rail strips, with different locking means are used here. As an example, on the DE 102 24 454 A1 directed. In aircraft, it is known to fix the seats on parallel rails. For this purpose, special seat attachments are required, the determination is usually done by screwing.

From the field of transport vehicles, such as bus construction, especially the wall-side seat attachment is known, as for example in the DE 27 15 548 A1 is described.

All these seat attachments are difficult to handle, so that usually does not move the seat. Today, however, this is increasingly demanded in bus construction, since the bus is not only intended for passenger transport, but also for the transport of, for example, carried bicycles, etc.

From the DE 10 2004 047 455 A1 a locking body with a locking part is known, which is engageable in a relative movement transversely to the longitudinal axis of the mounting rail in clamping engagement. For the said relative movement an eccentric drive of the locking body is provided.

A device of the type mentioned above is from DE 198 51 392 A1 known. Here, both a clamping device and an adjusting device are provided in a housing, the actuation of which takes place via cam slots or control cams.

TASK

Object of the present invention is to provide a device of o. G. To develop a kind that allows a secure fixing of the object, but also an easy release.

SOLUTION OF THE TASK

To achieve the object leads that for the actuation of the clamping device and adjusting device each have a separate lever and rotary lever is provided, wherein the lever covers the rotary lever in clamping position and shields.

This means that instead of cumbersome screwing the determination now takes place by the operation of a lever. A lever can be moved quickly, so that handling of the object is much easier.

This unit is hidden in a common housing, wherein the rotary lever for the adjusting device is arranged under the lever for the clamping device. The latter is od in clamping position by a split pin. Like. Set so that no accidental opening occurs. But this is also the same time the rotary lever of the adjusting device protected.

The fixing of the lever of the clamping device can also be effected, for example, by a locking mechanism at the end of the lever. For example. Here, a movable piece of sheet metal could cover an opening, wherein the sheet metal piece must be moved for unlocking. The sheet metal piece is integrated in the housing and provided with a return spring so that it would like to get into the closed position. Under this piece of sheet metal is then in the opening a lock, which can be opened with a key or even, for example. A square screw or a bolt that can interact with an Allen wrench. Here are many possibilities conceivable and should be encompassed by the invention.

In a particularly preferred embodiment of the invention, the lever of the clamping device may be connected to the rotary lever for the adjusting device, so that when the lever is opened, the rotary lever is also automatically pulled up. This means a greater ease of use. The connection can for example be done by a lateral overlap of the lever on the rotary lever, wherein the lever is virtually clipped onto the rotary lever. Again, many possibilities are conceivable.

The clamping device should have a sliding block, which engages in the groove. This shoe must be designed so that it can achieve a clamping effect. For example, this could be done by spreading in the groove. Preferably, however, an undercut is provided in the groove, in which at least a portion of the shoe can engage, so that it receives and clamps together with, for example, a rail strip a peripheral edge of the groove between them. For this, however, the shoe must be able to perform a movement, which happens with the lever. For this reason, the shoe is arranged on a guide punch, which passes through the rail strip just mentioned, wherein at the opposite end of the shoe guide shoe, the lever is articulated.

In a preferred embodiment, this lever now has an eccentric element with which the guide punch can be moved when turning the lever. For example, this is a pressure nose, which is eccentric in relation to the axis of rotation. The pressure nose cooperates with a pressure recess in which it slides when pivoting the lever.

Thus, the clamping effect is cushioned, disc springs are provided between the pressure trough and rail strips, so that a rattle noise is still effectively prevented even after repeated use of the clamping device.

In a preferred embodiment, the clamping device should also be assigned an adjusting device. This means that first the object has to take the desired position, which happens via the adjusting device. Only then is the object fixed by the clamping device on the rail.

In a preferred embodiment, the adjusting device consists essentially of a height-adjustable punch, which cooperates with a rotary lever. This stamp is similar to the guide punch in an opening in the rail strip movable. However, it can disappear completely in the rail strip, so that it no longer protrudes in the direction of the rail. So he can not disturb when moving the object along the rail also.

This stamp is insertable for adjustment in an opening in the rail. This movement is, supported by, for example, a coil spring as an energy storage, caused by the pivoting of the rotary lever about an axis of rotation. This axis of rotation passes through a slot in the stamp, so that the punch can be moved vertically relative to the axis of rotation. The rotary lever itself preferably engages on both sides with a link in each case a shoulder on the stamp, wherein the gate is designed so that during an opening movement of the rotary lever of the punch is raised. As the rotary lever is rotated in the opposite direction, the shoulder slides downwardly along the gate under the pressure of the aforementioned coil spring.

Thus, when the article has reached the desired position on the rail, the adjusting device is released, so that the stamp, unless he immediately engages in a corresponding opening in the rail, stands up on the rail under the pressure of the coil spring. Now, if the object still slightly shifted along the rail, the stamp reaches the next assigned to him opening on the rail and enters this opening. Only then is the clamping device actuated.

The present embodiment of the device incidentally has the effect that the lever outside the airline rail is not lockable. This is due to the fact that the axis of rotation of the lever of the clamping device outside the position of use maintains a different distance from the rail strip, as in the position of use in the airline rail. Outside of the position of use, the plate spring package pushes the axis of rotation at a greater distance from the rail strip, so that the end of the lever does not congruent with the counterpart of the closure on the rail strip.

As a rail, especially an airline rail in question, as in the DE 299 12 413 U is described. This airline rail is particularly suitable for installation in aircraft, buses, ships or similar means of transport.

According to 1 is an inventive device P for fixing a seat base 1 on an airline rail 2 shown. It sits on a railroad track 3 a housing 4 on, in which a clamping device described below and adjusting device for the seat 1 are located. Of the clamping device is only a sliding shoe 5 shown at a guide stamp 6 is arranged. Further protrude from the rail to the railroad track 3 more sliding shoes 7 starting in a not-shown groove of the airline rail 2 slide.

As in 3 recognizable, is the housing 4 about one in a hole 8th in the rail strip 3 engaging adjusting bolt 9 and one in a threaded hole 10 in the rail strip 3 engaging bolt 11 on the railroad track 3 attached.

In 4 Now the housing with the adjusting bolts and bolts is omitted, so that separated a clamping device 12 and an adjustment device 13 are recognizable. For the clamping device 12 a lever acts 14 with the guide stamp 6 together. The guide stamp penetrates 6 the rail strip 3 , a plate spring package 15 and a pressure well 16 in which a pressure nose 17 ( 5 ) of the lever 14 can pivot or slide. Here is the guide stamp 6 opposite the shoe 5 over a rotation axis 18 with the lever 14 connected.

The adjustment device 13 has a height-adjustable stamp 19 on, in an opening corresponding to its outer contour 20 in the rail strip 3 slides. This stamp 19 has a slot 21 which also runs vertically and from a rotation axis 22 is enforced. This rotation axis 22 is at an in 8th shown bearing block 23 set by the railroad track 3 rises. Furthermore, on the axis of rotation 22 a rotary lever 24 set that around this axis of rotation 22 can be swiveled. The rotary lever 24 embraces the stamp 19 bifurcated and forms to the stamp 19 in each case a backdrop on both sides 25.1 respectively. 25.2 out, each one on the stamp 19 formed lateral shoulder 26.1 and 26.2 under attack. The design of the backdrop is in the 9 and 10 better recognizable, where there is also a control edge 27 that with the shoulder 26.2 interacts, is highlighted. The scenes 25.1 and 25.2 are in cooperation with the shoulders 26.1 and 26.2 designed so that when turning the rotary lever 24 around the axis of rotation 22 around the stamp 19 Lift. This happens against the force of a coil spring 28 , on the one hand, against the axis of rotation 22 and on the other hand against a stamp base 29 supported.

The operation of the present invention is as follows:
If a vehicle seat is to be fixed, for example, in a bus, two spaced-apart airline rails are located in this bus 2 provided, which extend parallel to each other in the longitudinal direction of the bus. This airline rail 2 is in the DE 299 12 413 U to which reference is made. The seat is now on both sides near his respective seat 1 provided with a device P according to the invention.

The arrangement of the sliding shoes 5 and 7 and the stamp 19 now allows insertion of the seat anywhere on the airline rails. The sliding shoes 5 and 7 engage in the region of the opposite edge edge recesses in the longitudinal groove in the airline rail, so that the seat with raised punch 19 along the airline rails 2 can be moved. It is Z. B. possible to move all the seats of a row of seats forward, so that a rear area of a bus can be used as a cargo space. Furthermore, of course, also possible, the seat at any point from the airline rails 2 to take.

Moreover, a sliding aid is preferably arranged on the underside of the rail strip. This can be, for example, a clipped-in slider made of plastic, a self-adhesive plastic tape or else a lubricant application (eg Molykote) or the like.

To seat the seat at a desired position, the seat will be along the airline rails 2 moved, with clamping device 12 and adjusting device 13 corresponding 7 . 8th and 9 are solved. That is, an end face 30 of the stamp 19 is in the plane of a sub-surface 31 of the railroad track 3 , The sliding shoe 5 is in a position in which it is a farthest distance a from this lower surface 31 of the railroad track 3 comply. In this distance range a, the marginal edge of the airline rail 2 glide undisturbed.

Now, if the desired position of the seat is reached, the adjusting device 13 solved, with the rotary lever 24 clockwise about the axis of rotation 22 is pivoted. At the same time the shoulder slides 26.1 respectively. 26.2 of the stamp 19 along the respective backdrop 25.1 respectively. 25.2 from one of the rotation axis 22 distant position to one of the axis of rotation 22 close position, which at the same time lowering the punch 19 under the pressure of the coil spring 28 means. The Stamp 19 so drives out of the railroad track 3 from and into a circular, formed by the opposing troughs opening of the airline rail 2 one. If this is not done properly on the first attempt, the seat can be positioned along the airline rails 2 slightly shifted until the stamp 19 locks.

Next is the lever 14 also clockwise around the axis of rotation 18 rotated, which means that the pressure nose 17 an increased pressure on the pressure trough 16 exercises and thus the leadership stamp 6 and with this the sliding shoe 5 attracts. As are parts of the shoe 5 in undercuts the groove of the airline rail 2 located in the area between two adjacent troughs of the airline rail, it comes to a pinching of the edges of the airline rail 2 between shoe 5 and lower surface 31 of the railroad track 3 , This is now the railroad track 3 on the one hand by the stamp 19 against slipping and the other by the shoe 5 secured against a rattle. In this closed position, the lever covers 14 , as in 2 and 3 shown the rotary lever 24 so that it is protected against unintentional loosening. In this closed position, the lever 14 or preferably secured by a split pin or the like.

To release the seat, the lever 14 pivoted counterclockwise, which means that the train on the shoe 5 subsides. Thereafter, the rotary lever 24 also pivoted counterclockwise, creating the backdrop 25.1 and 25.2 in cooperation with the shoulders 26.1 and 26.2 the stamp 19 Lift against the pressure of the coil spring 28 , Towards the end of the rotary motion has the backdrop 25.1 respectively. 25.2 a flattening 32 on, leaving the shoulders 26.1 respectively. 26.2 on the flats 32 sit up and the rotary lever 24 remains in its vertical position without having to be specified specifically here. The vehicle seat is now free and can travel along the airline rails 2 be moved.
