Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for locking a railway vehicle coupler, particularly during a locking movement of a knuckle.
It relates to a guide mechanism that guides the lock from the released position to the locked position.

Conventional lock guide mechanisms have a structure in which, under certain conditions, the lock does not necessarily fall into the locking position during the locking movement of the knuckle.

During closure of the knuckle, a conventional lock guide mechanism was provided within the movement path of the lock to return the lock to the locked lock position.

This structure has the disadvantage that the railway cars equipped with the coupler cannot be properly connected.

The present invention aims to provide a lock guide device which obviates the drawbacks of the prior art.

-Purpose L is usually accomplished by a locking guide mechanism provided along the arm side wall of the coupler housing.

The guide mechanism of the present invention has a lock guide along the rear side of the lock chamber on the arm side wall of the right side of the connector.

The locking guide includes a guide surface that is inclined at an acute angle relative to the longitudinal axis of the coupler housing, at least a portion of its length.

At this time, the oblique guide surface is provided at a position where the lock can move from the released position to the locked position without interference, no matter how the knuckle is operated.

Other features of the invention will be readily understood from the following description with reference to the accompanying drawings.

The drawing shows a coupler 10 incorporating a lock guide device 11 according to the invention.

The main body of this coupler 10 is a coupler housing 12, and this housing has a knuckle side wall 13 on the left side and an arm side wall 14 on the right side.

The knuckle 15 is pivoted to the knuckle side wall 13 for movement between a released position and a locked position.

A knuckle opening 16 is supported within the housing 12 and cooperates with the knuckle 15 in a conventional manner.

A locking device 17 is mounted on the outer surface of the housing so as to be activated by a release lock (not shown), and is a lock 22.
an elongated, sloping toggle slot 19 provided in the leg 21 of the
It has a trunnion 18 fitted therein.

The lock 22 has a standard structure and is disposed within the lock chamber 23.

As shown in FIG. 4, the lock 22 has a forwardly projecting fulcrum 24, and the rear wall 29 of the upper lock includes a rear guide 28 and a lower chamfered surface 31 on the left side.

In the portion where the rear wall transitions to the lower part of the lock, two notches are provided in the lower part of -L in a substantially horizontal direction, and the upper part forms a knuckle opening seat 26, and the lower part forms a lock fixing seat 27.

The leg 21 near the lower end of the lock is provided with the toggle slot 19 in the direction of the lateral force.

The knuckle side wall of the lock chamber 23 has a lock guide 32 extending downward from the housing 12 as well.

Lock guide 320 guide surface 33 contacts rear guide 28 on the upper left side of lock 22 to guide movement of the lock between the released and locked positions.

In the locking position, as shown in FIG. 1, the knuckle opening seat 26 rests on the knuckle leg fixing seat 34 of the knuckle opening 16, and the fulcrum is in contact with the locking surface.

Conventionally, a guide device has been provided along the arm side wall of the coupler housing, but this configuration has a tendency for the lock fixing seat 27 to catch on the knuckle leg fixing seat 34 of the knuckle opening 16 before lowering to the locked position. There is.

This results in minimal partial contact between the locking mechanism and the knuckle locking surface, so that a secure locking of the knuckle to prevent release is not achieved.

Arm side wall-E according to the present invention [? The lock guide device 11 is provided on the rear side of the lock chamber 23 in order to eliminate the above-mentioned drawbacks.

For this purpose, the arm side wall lock guide device 11 extends between the longitudinal axis 35 and the outer wall of the housing 12, i.e. the rear wall of the locking chamber along the arm side wall, and has an inclined guide surface 36.
is formed, which guide surface contacts the chamfered surface 31 of the lock as the rear guide 28 slides along the knuckle sidewall lock guide 32.

This inclined guide surface 36 connects to an upright surface 37 perpendicular to the longitudinal axis of the coupling housing 12.

This inclined guide surface 36 is inclined at an angle a with respect to a line perpendicular to the longitudinal axis 35, and holds the lock fixing seat 27 so as not to come into contact with the knuckle leg fixing seat 34 while the lock 22 moves downward to the locking position.

The angle of inclination a can vary from 18° to 45°, but is usually 24°.

In this manner, movement of the lock 22 from the released position to the locked position is smooth and unobstructed.

In the locked position, the surface 37 upright relative to the longitudinal axis contacts the rear wall 29.
