from doors and for similar purposes.

The subject of the present invention is one shown in several modifications * Device which can be rotated in connection with any one about its suspension point Organ, such as a door, the seat of a folding chair or the like, is brought, and should serve to block the organ in question until it is triggered by the A specific coin has been inserted.

In. the example shown in Fig. 1 to 3 is connected to the pivot α rotatable chair seat A, an arm D , the free end of which is passed through a cutout d of the housing B and is provided with two concurrent approaches d ¹ d ² , which the through Insert the coin e into the slot C with the seat open. In this initial position, the latter is based on its periphery on an approach E of the housing B and is held laterally between the approaches d ^x d ^% (FIG. 2).

Above the arm D , a locking hook F is rotatable about a pin f in the housing B and is arranged in such a way that its nose / ² presses on the upper edge of the arm D under the influence of a spring / ^{1 near the money slot.} The locking hook F is also connected to an arm / ⁴ , which is shaped so that after the money has been inserted and when the seat A is folded down, the coin holds the locking hook lifted and can pass under it, in order to then slide off the attachment E and into the lower one Part of housing B to fall.

The nose / ^{2 of} the locking hook is also arranged in such a way that it would fall into the slot between d ¹ d ² and thus prevent the movement of the chair seat A if an attempt was made to fold the seat down without first receiving a coin from the required Size which alone is able to lift the locking hook in a proper way, to have put into the slot.

In the modification shown in FIGS. 4 and 5, a curved arm / is connected to the chair seat A swinging around pin α, in the tooth attachment j ^{2 of} which a locking hook K rotatable about the bolt k is located below without a prior insertion of a suitable coin. depends on the influence of a spring k ¹ . The coin inserted through a slot C in the housing B falls through a gap in the hook K into a matching slot in the arm J onto the supports L and L ¹ , which support the coin in such a way that it falls into the slot in the arm when the chair seat is folded down. held, is pulled around the roller / the support L and, as indicated by dotted lines, abuts with its protruding edge against a sliding roller k ^{3 of} the hook K, in order to raise the latter during the further movement so far that its nose k ² over the nose j ^{2 of} the arm J is carried away. In the further movement the coin finally falls from the support L into the container B, and the hook K then slides on the rear part of the arm J, against its upper and lower edge of the front

Claims (5)

Theiles the springs-j and j Create ¹ to prevent the penetration of dirt through the opening in the housing wall. Finally, FIGS. 6 and 7 show a modification of that shown in FIGS Arrangement, such that the release, instead of a larger coin, - by two minor is effected. The arm J and hook K are designed similarly as in Fig. 4 and 5. The first inserted coin e ² falls completely through the slot of the arm J between two rails N and, on a lever O swinging around the pin O, its other Arm rests against the face of the curved arm J. The second coin e ¹ falls on the upright coin e ² and is held in the slots, the ratchet K and the arm J. When the chair seat is folded down, the coin e \ is pulled around by the arm J , as before, its upper edge acts against the roller k ^{a of} the hook K and lifts it accordingly far, while at the same time the lever O, the movement of the arm J following, swings around so far that finally both coins can fall into the collecting space of the case -B. _t Patent claims: i. Device for automatic charging for the use of chairs, the opening of doors and for similar purposes, characterized by the arrangement of a locking latch F below the coin slot C in the fixed housing B and the arm D swinging around the pin α , between its lugs d ¹ i ² ■ the coin supported on the approach E of the housing is held until the slot of the arm D has passed under the locking latch F (Fig. 1 to 3). 2. The modification of the device referred to in claim 1, consisting in that the arm J , which supports the inserted coin laterally and rotates about the pin α, is locked by the trap K encompassing the coin laterally and thereby triggered from the tooth j ^{2 of} the arm / is that it is raised by the coin resting on L with the turning movement of the arm J until its nose / f ^{2 can} slide unhindered over the tooth attachment _ / ² (Figs. 4 and 5). 3: The modification of the device referred to in claim 2, consisting in the fact that an inserted coin is held laterally by a rail JV and by one as a double-armed lever. formed support O is carried in such a way that the release of the locking latch is only brought about by a second coin inserted and supported on 'the first coin.
