Description

IMPERIAL,

PATENTAMJ.

The thought of the movement of movable organs, e.g. B. of bars, to the circuit Using a counter is in and of itself no longer new and already has to Production of so-called control locks for cupboards, chests of drawers and similar containers, where they have the purpose of notifying the owner of the unauthorized opening of the container.

However, these control devices suffer

ίο the inconvenience that they can be returned to their previous position relatively easily or quickly after unauthorized use, since the ratchet wheel and with it the counting disk by means of a curved nail placed on its axis or by means of pliers over the locking point into the original position can move on. .

The invention aims to eliminate this drawback and, thus, the flawless Detection of unauthorized opening of the with the new device provided container, so that complaints in connection with any claims for damages will find their legal justification. '

The new purpose is achieved in that the unauthorized rotation of the counting disc of the Counter to the zero position and also to the one preceding the unauthorized opening Position by a combination lock

is prevented. ,

The new control device is intended especially for suitcases, travel bags, caskets and others Containers find use that used to, rail, ship and wagon transport will. In these cases, the position of the counting disc when checking in the baggage

Piece is noted on the accompanying paper (waybill / baggage receipt, etc.) so that unauthorized opening during transport can be detected immediately upon acceptance of the baggage and the transport company can be used to provide compensation .. · ¹

On the drawing, the invention is in one exemplary embodiment shown.

Fig. Ι is an elevation. Fig. 2 shows the closed Apparatus with the protruding combination rollers of the combination lock. Figure 3 illustrates the back of the control lock with the control sign visible. Fig. 4 shows the container with the control apparatus attached.

The lock or the apparatus has the shape of a box lock and is attached by means of screws or rivets to the inner front of the container (suitcase and the like) in such a way. that when the container is closed, the lid of the same rests on the top of the lock box. '■.;; [ _: ;

In the lock case i sits the pin α, which is influenced by a spring c; protrudes from the top of the lock case when the container lid is open, while it is pressed into the lock case by the latter when the container lid is closed. A resilient gripper δ is arranged on the pin α and engages the teeth of the ratchet wheel d '.

Each time the pin is lifted up by the spring c, d. ¹ ii. Each time the container is opened, the gripper δ pushes the ratchet wheel one tooth further.

In order to prevent the ratchet wheel from going back, locking

Claims (1)

springs f, g arranged, of which the spring g already engages in the teeth of the ratchet wheel and makes its backward movement impossible when the relevant tooth of the ratchet wheel has only risen by a quarter. It is therefore also impossible to continue turning the ratchet wheel by holding it down when the container lid is initially opened. of the pin α by means of a flat instrument ίο (knife blade, etc.) to prevent and thereby to disguise the unauthorized opening of the container. Next to the ratchet wheel d , the control disc e is attached on the same axis, which rotates with the ratchet wheel, and on the side of the ratchet wheel facing away from the tooth pitch of the ratchet wheel, numbers are attached, which are inserted through an opening in the lock case at a suitable point (Fig. 3 ) are visible from the outside. 'Each time the container is opened, appears behind this opening another number, so that the owner of the container is certain whether and how often the container has been opened without his knowledge, In order to prevent the perpetrators by repeated up and down the pen a the Schaltradi? rotates until the old mark is visible again behind the viewing opening, a thumb "or tooth k is arranged on the disk e at its zero position, against which the resilient pawl i is supported, preventing further rotation of the disk. This pawl can only be lifted with the key h of a combination lock, the barrel of which can be pressed against the pawl i when the lock is in the open position, while with twisted combination rollers it is caused by attachments attached to the barrel, which then have a dead gear in the spaces between the rollers, is kept away from the handle. By lifting the pawl i , the thumb k is free, and the disk "e can now be brought into another position beyond the zero position. Since the setting of the combination lock, which can be used in any version, is only possible with a certain setting of the drawing rolls I ₁ m _s n, 0 , which is only known to the owner, only the owner can return the control disc to its initial position beyond the zero position, and consequently, even in the event that the disc is in a different position, the unauthorized opening of the container can be properly established. , The particular design of the control device depends on the type of container. ■ Patent claim: Control device with counter for suitcases and the like, characterized in that an unauthorized rotation of the counter to the zero position, and beyond that in the position preceding the unauthorized open by a combination lock known Kind is prevented. 1 sheet of drawings.
