CN1267045A - Storage locks for transport vehicles - Google Patents

Abstract

The present invention relates to a parking lock for transport vehicles, which serves to lock vehicles together at a parking post. Release is achieved by handing over a parking tag, which itself remains locked in the parking lock until the vehicle is reconnected. It is important that, when the parking tag is inserted into the parking lock, it undergoes an additional movement perpendicular to the insertion direction due to the action of an adjusting element provided in the parking lock.

Description

Storage locks for transport vehicles

The invention relates to a storage lock for transport vehicles, which is used to interlock vehicles located at a parking column, that is, by enabling the lock of one vehicle to be locked in the storage lock of an adjacent vehicle, At this time, the loosening of the car preferably located at the end of the column can be carried out by virtue of the delivery (insertion) of the deposit card, and the deposit lock locks the deposit card when the car is released, and on the other hand, the deposit lock is re-locked to the When the car releases the deposit plate, this is achieved in that the deposit lock has at least one regulator, which cooperates with the deposit plate and has at least one regulator to directly or indirectly lock or release the key.

There are many different structural forms of this type of deposit lock on the market at present. Because the loosening of the car can only be possible by inserting the storage card into the storage lock, and the user can take back the storage card when the car is re-locked at different assembly locations, so there is no phenomenon that the car is uselessly placed indiscriminately. In this case, personnel for finding, collecting and returning the vehicles are saved and a small amount of payment is sufficient, because unused vehicles are always kept centrally where they are needed for use.

Usually all require to use some kind of coin as deposit card, and at this moment, most deposit locks only use a kind of fully definite coin action. However, it is also known that deposit locks are provided with two coin slots so that they can be selectively operated with two different coins. However, this increases the mechanical component costs for the lock.

Furthermore, deposit locks are known which have a so-called coin slide, in which case the coin slide can be selectively equipped with two different coins. But this coin slide will significantly increase the size of the storage lock.

Proceeding from this, it is the object of the present invention to improve the known depository lock as follows so that it can be adapted to different coins, while also having an economical and compact design.

According to the invention, this object is achieved in that when the deposit tag is inserted into the deposit lock, it is subjected to a movement perpendicular to the direction of insertion by the actuation of at least one adjusting element thereof.

This is preferably a lateral movement outside the insertion movement with a fixed coin slot and no coin slide, with the result that the deposit card is locked in the deposit lock due to its offset (Versatz) towards the coin slot , until at least one adjustment member makes the deposit board return movement.

The above-mentioned offset in the lateral direction of the storage tag enables the locking of the storage tag even if it does not have an exactly corresponding diameter, but is approximately two millimeters smaller or larger. In this way, the deposit lock can be operated with different coins, so for example with a one-mark or a two-mark or with a corresponding equivalent in Eurocurrency, without additional actuating elements or mechanical changes.

It is particularly expedient for the deposit card, after it has been displaced in the transverse direction, to be locked on its side opposite to an adjustment element by a fixed part, in particular the lock housing or a part connected thereto, against extraction. Thereby, a very stable locking is obtained, without the need for any auxiliary parts of the lock housing.

In order that the permissible range of diameters is to be limited, it is proposed to provide two adjusting elements, which are connected to each other when inserting the deposit tag and hook into each other when using a deposit tag with an impermissible diameter. This is particularly advantageous in that a mechanically fixed upward diameter limitation is pre-set, that is to say, the upward diameter is limited by correspondingly dimensioning the coin insertion opening, and on the contrary, the upward direction is limited by interlocking the adjustment elements. The lower (lower limit) diameter.

Furthermore, it is advisable to design one adjustment element in the form of a pivoting lever, and the opposite adjustment element in the form of a simple elastic element, in particular a moving element, in order to allow the lateral movement of the deposit card. Can be carried out along the direction of the above moving parts.

It is reasonable that the two adjusting parts are pretensioned by springs in the circumferential direction of the storage tag.

Furthermore, it has also proved to be advisable that the actuating element which pivots causally for the lateral deflection additionally catches the deposit plate on its upper and/or lower side. As a result, it can be guided more reliably and a thickness limit can thus be prescribed at the same time.

The locking and releasing of the key is preferably carried out by means of an intermediate part which is actuated or released by means of the adjusting part. This intermediate part can be designed in the form of a rotary part which lies in the plane of movement of the adjusting part and is operatively connected by its ends to at least one adjusting part such that the two lock each other in their respective end positions.

Further features and advantages of the subject matter of the application result from the following description of some embodiments with reference to the accompanying drawings; shown here:

Fig. 1 shows the vertical sectional view of the register lock before releasing;

Figure 2 shows the same lock in top view with the cover removed;

Figure 3 shows the lock according to Figure 1, but in fully inserted coin and released state;

Fig. 4 shows the same view as Fig. 2, but is in the working state as Fig. 3;

Figure 5 shows the same view and working position as Figure 4, but with the coin partially pulled back;

FIG. 6 shows the same top view as FIGS. 2 , 4 and 5 , but at an impermissibly small size for the check-in card.

According to the storage lock according to the invention, in all embodiments, it consists of a housing 1 mounted on a transport cart, which has a coin slot 1a on one side and a slot 1b for inserting the key 2 on the other side. . Plug key 2 itself is connected with adjacent car or assembly place with a chain 2a.

Inside the housing 1 are arranged a first adjusting part whose shape is a rocking plate 3 and a second adjusting part whose shape is a moving part 4 opposite thereto. When the rocker plate 3 is swingably supported on a pin shaft 6 in the housing, the moving member 4 is movably guided in the housing 1 substantially radially towards a deposited coin 5 inserted through the opening 1a, at this time, The two adjusting parts are positioned so that when the deposited coin 5 is inserted, it contacts its periphery and at substantially opposite positions. For this purpose, the rocker plate 3 has a slightly concave and arched contact surface 3a, while the moving part 4 has a corresponding contact surface 4a.

For better guidance of deposit coins 5, rocker plate 3 not only has a support surface underneath deposit coins, but also has an additional finger 3d which extends on the upper side of the coins. As a result, the coin is guided at two approximately opposite positions on its circumference and also at the bottom and at the top.

The rocker plate 3 is operatively connected at its other end 3b to a rotary part 7 in a locked state. The rotating part 7 is supported in the housing 1 by means of a horizontal pivoting spindle and has a transversely extending groove 7a at its end corresponding to the rocker plate 3 (see FIGS. 1 and 3). The end 3b of the rocker plate 3 is pressed into this groove by means of the elastic element 8, so that in this pressed-in position the rotation of the rotary part 7 is locked.

The rotating part 7 itself has a hook 7b on its circumference, which extends into the hole 2b of the key 2 at the position of the rotating part 7 shown in Figures 1 and 2 and locks it so that it cannot be pulled out from the deposit lock. . The key can also have one or two side notches instead of holes, so that one or two protrusions can engage the notches instead of hooks 7b.

FIGS. 1 and 2 also show the situation in which the cars belonging to the shown deposit lock are engaged in a train or assembly point where the deposit lock is locked with the plunger key 2 .

In order to release the car, the storage plate 5 must be pressed slightly deeper into the storage lock. This state is shown in FIGS. 3 and 4 .

In Fig. 4 or when the storage card 5 in Fig. 5 is pulled out, it is known that the pressing of the storage card makes the rocking plate 3 swing, and at the same time the moving part 4 is pressed back, and they respectively resist the force acting on the two regulating parts. Spring 8 or 4b. At the same time, it is also known that due to the pivoting of the rocker plate 3, the deposit coin 5 makes an at least approximately arcuate movement and is then deflected perpendicularly to the direction of insertion (downward in FIG. 4). The moving part 4 is pressed down by this deflection against the action of the spring 4b to such an extent that the hooks 3c and 4c provided on the rocker plate 3 and the moving part 4 can pass through each other, thereby allowing a gap between the two adjusting parts. No hooking occurs.

During the pivoting process of the rocker plate 3, its end 3b is pulled out of the groove 7a of the rotary part 7, whereby the rotary part is no longer locked. Thus, it can be swung clockwise by means of the compression spring 9 into a position which can be seen from FIG. 3, at which point the hook 7b moves outwards from the key 2 and releases it. In FIGS. 3 and 4 the key 2 is shown already in the withdrawn position.

As a result of the rotation of the pivoting member 7, its slot 7a is no longer in a position where the end 3b of the rocker plate can pass through. Consequently, the rocker plate 3 can no longer be swiveled back and thus the deposited coins 5 can no longer be removed, since the end 3a partially blocks the coin opening 1a.

Certainly, as shown in Fig. 5, the deposited coin 5 can also be slightly pulled outward. However, it is still locked between the contact surface 3a and the edge 1a of the coin slot.

Can also know from Fig. 5, deposit lock also can work with a slightly larger deposit coin equally, and this is because, mobile member 4 is as the effect of elastic passive supporting element, and it itself does not play a role in the locking of plug key. The permissible diameters can also vary and can be defined simply by dimensioning the insertion opening 1a taking into account the maximum value.

The regulation of the lower limit of the diameter takes place via the hooks 3c and 4c, as can be seen from FIG. 6 .

Figure 6 shows an impermissibly small deposit coin 5'. In fact it can be inserted into the deposit lock and also allows the rocker plate 3 to make a small swing. However, due to its small diameter, it cannot further sufficiently distance the moving member 4 from the rocker plate 3 . This has the consequence that the rocker plate 3 hooks with its hook 3c on the hook 4c of the mobile part 4 during its pivoting movement. The end portion 3b of the rocker plate also cannot come out of the groove 7a of the rotary part 7, so that the rotary part is still locked, so that the key 2 cannot be extracted from the deposit lock.

Only the deposited coin whose diameter is large enough to push the mobile part 4 further enough can release the key 2 as shown in FIGS. 2 and 4 .

For the interaction of the adjustment part 3 with the key 2, there are many possibilities for the professional, the adjustment part is made here in the shape of a rocker, but it can also be a single-armed lever. Thus, for example, the adjustment element 3 can engage directly or via a displacement block with the hole 2b of the key 2 or with a notch in the side, so that the rotary element 7 becomes superfluous. It is then only necessary to provide an additional locking element, whereby the deposit card remains locked in the coin lock after the key 2 has been released. In this respect, reference may also be made to known locking mechanisms.

Overall, the present invention also has the advantage that the adjustment element 4 acts only passively to a certain extent and, through its elastic mounting, allows deposit tags of different sizes to be accommodated by the other adjustment element 3 . In addition, the active adjustment element 3 subjects the deposit coin to a lateral deflection, so that the adjustment element 4 is no longer responsible for locking the deposit token, but the part fixed on the housing. Last but not least, the interlocking of the two adjusting parts precludes the use of impermissibly small deposit coins.
