Abstract
In the closed state, a cover of the transport container strikes against an actuation element and displaces this element in the direction toward a contact device. The actuation stroke of the actuation element is only sufficiently large when a counter bearing of the actuation element is preformed in the direction toward the contact device when a catch which engages in the cover is brought into its final position. The inventive locking device is employed for transport containers which are placed upon an electrically driven traveling device running on rails, wherein the rail lines are laid out in such manner that the traveling device can be driven horizontally and vertically.
Claims12
A locking device for a transport container of an electrically driven rail-bound transport car, comprising support means for operative association with a transport container which is to receive a cover in closing relation thereto, a catch carried by said support means and movable from a disengaged position to a fully engaged position, the catch is said fully engaged position being operative for securely retaining the cover in said closing relation to the transport container, a contact device secured to said support means in the vicinity of said catch for monitoring the locking state of the catch with respect to the cover and being actuatable in response to fastening of the cover in said closing relation by means of said catch, an actuation element mounted by said support means so as to be engageable with the cover as the cover is moved into said closing relation to the transport container, and being resiliently urged by a spring force toward a non-actuating condition relative to said contact device, a bearing controlling movement of the actuation element to an actuating relationship to said contact device, said bearing being movably mounted by said support means and being movable by a portion of the catch as the catch is moved toward said engaged position, toward an enabling position, said bearing when in said enabling position being disposed to enable actuation of the contact device by the actuation element, said bearing when not completely moved to said enabling position by the catch because of the catch not being fully moved to its fully engaged position, preventing actuation of the contact device even when the actuation element is deflected against the spring force by means of the cover being disposed in its closing relation to the transport container, and said actuation element being movable to actuate said contact device only when the cover is in said closing relation to the transport container and the catch has been fully moved to its fully engaged position relative to the cover.
