1. Field of Technology
The present application relates to a device for locking an equipment item onto a locking track attached to the floor of a cabin, including two parallel retaining edges divided by a longitudinal slot and a number of spatially separated openings, wherein the device has on its upper side means for locking the equipment item and on its lower side includes at least two locking projections the size and the arrangement of which are adapted to at least two adjacent openings, and wherein by shifting the locking projections in the longitudinal direction of the locking track until the locking projections are located between two adjacent openings, a positive connection between the device and the locking track can be produced.
2. Brief Description of Related Art
Such a device is known from U.S. Pat. No. 5,871,318, for example, and is used in particular for the longitudinal shifting of aircraft seats along locking tracks that are attached onto the cabin floor of an aircraft. In order to fasten the aircraft seats onto the locking tracks, the device is initially aligned such that a support component with molded projections is aligned with the circular openings, so that this can be moved through the longitudinal slot in the locking track. The support component is then moved by half the distance between adjacent openings in the longitudinal direction of the track, wherein the T-shaped cross-sectional projections engage behind the retaining edges on both sides of the locking track and prevent the support component from coming out of the locking track. In a third step, locking parts having a corresponding contour are then moved down by the support component, so that these are retained in the openings which are now located below. In this context, the locking parts are pushed against the retaining edges, which results in locking the support component and thus the seat attached to it in the track.
In this case it is disadvantageous that the support components, after having been inserted into the locking track, must be moved as accurately as possible by half the distance of the opening, so that the locking parts engage into the openings and thus making secure locking possible. Since several seats are normally combined in one row and are arranged on one seat support, it is necessary that this entire row of seats must be moved. This process requires some time for assembly, particularly if the distance by which the row of seats is shifted deviates too greatly from the setpoint, and locking is not possible initially until some fine alignment has been done. This shifting process can also result in some tilting and can thus produce jamming.
