Abstract

The coin deposit lock comprises a functional part (5) that, by means of a key (1) or coin (2), is moved between two final positions inside a coin compartment (3) and comprises a housing that forms a coin compartment (3) and a key compartment (4). Said functional part alternately releases or blocks the key and the coin. First and second control contours (55A, 55B; 56A, 56B; 57A, 57B) are formed on the function part (50) on both sides of the longitudinal axis (L-L) of the housing (40). In the event of a direct mutual action by the key (10) or coin (20), these control contours cause the functional part (50) to vertically move perpendicular to the functional plane between two high positions (H1, H2) according to both final positions of the key and coin. In addition, first and second blocking contours (58A, 58B; 59) are formed on the functional part (50) and are provided for blocking the key (10) or the coin (20) in the high positions of the functional part (50). All functions of the coin deposit lock are completely integrated in the functional part, which is directly subjected to the action of the coin and key and controls the mutual release/blocking of these parts.

Description

Coin deposit lock

Technical field

The present invention relates to a kind of Coin deposit lock (Muenzpfandschloss), especially be applied to the Coin deposit lock of shopping cart.

Embodiment

The first embodiment explanation

Described Coin deposit lock mainly is made up of four parts according to first embodiment, that is, shell that is rectangular parallelepiped shape substantially 40, one can be embedded into the functional part 50 of these shell 40 the insides, a spring members 60 and a cover plate of outer casing 30 that is contained between shell and the functional part.As common arriving in Coin deposit lock, between these structure members, has the space that is used for that a key 10 injected the space of a key chamber 12 and is used for coin 20 is injected a coin chamber 22.

By Fig. 1 and 2 basic structure of shell 40, cover plate of outer casing 30 and functional part 50 as can be seen.

Described shell 40 comprises a base plate 41, the first guiding

part

41A, 41B extends out from base plate with the form of the axle journal that is shaped in longitudinal axes L-L both sides, described shell 40 also comprises a front end and

center guide piece

43 and 44 rear end, and they are used to locate correctly load function parts 50 and cover plate of outer casing 30.

Guiding space

42A, 42B are formed on the first guiding part 41A/41B the inside of axle journal shape.

Described functional part 50 is made up of a base plate 51, extends wall member from base plate like this, makes them be configured for the control and the locking profile of determination device function:

The

first control profile

56A, 56B is positioned at 22 places, coin chamber with the form that tilts the upwardly extending dip plane of angle about 30 ° to 40 ° with surface level, and these dip plane are arranged on the end of coin chamber 22.

On the leading section of control assembly (functional part 50) and at the first control profile 56A, the top of 56B constitutes the first locking profile 58A pincerlike, that be positioned at the coin side, 58B, their task is, makes that a coin 20 is counter to be stuck in the position of insertion and to prevent to take out this coin thus.

The

second control profile

57A, 57B is positioned at the key side with the form of dip plane equally, and has the second locking profile 59 of a spindle nose shape below a central plane ME-ME who sets with respect to this second control profile.At this particularly importantly, the first/the second control profile and the first/the second attached locking profile are positioned at the above and below of central plane ME-ME (Fig. 2) respectively mutually, are used for the mutual location of assurance function parts 50, also will describe this location below.Clear in order to represent, outstanding especially control profile 56A in Fig. 2,56B and 57A, 57B.

Side boss 52 with fundamental triangle xsect is positioned at the middle part of functional part 50, and it will be described below with the function that a volute spring (spring members 60) that is embedded into shell 40 the insides combines.

Described Coin deposit lock is upwards by 30 sealings of a cover plate of outer casing, it constitutes on a base plate 31 substantially, guiding

part

31A and 31B extend downwards from base plate, design their size like this, make them embed the guiding space 42A of

shell

40,42B, and therefore guarantee cover plate of outer casing 31 in shell 40 not only level and also vertical location, as what in Fig. 2, represent by a line.

When the assembling Coin deposit lock, at first functional part 50 is put into shell 40 the insides, stull shape parts of wherein said base plate 51 are embedded into the first breach 41C the inside of base plate 41, and the convex shoulder 59A of a corresponding downward formation of locking profile 59 is embedded into the second breach 41D the inside of a key side of base plate 41, guarantee that thus described functional part 50 only can (with small gap) carry out a vertical movement, the downward base plate 41 by shell 40 of this motion limits the base plate 31 that makes progress by cover plate of outer casing 30 and limits.

Be put into the middle part that a volute spring (spring members 60) is put into after shell 40 the insides Coin deposit lock at functional part 50, it not only side support on key 10 and coin 20, and be bearing in the middle on the boss 52.Described helical spring task is to guarantee that described functional part 50 can only occupy a height and position in two height and positions constantly, as shown in Fig. 3 and 4.

In order to finish assembling cover plate of outer casing 30 is placed on the shell 40 at last, wherein as mentioned above, (guiding part 31A 31B) is embedded into the space 42A of shell 40 to the guiding profile, the 42B the inside.

Assembling is finished described Coin deposit lock and a coin 20 can be injected coin chamber 22 or a key 10 is injected key chamber 12 in coin slit or key slit thus, wherein the basic functional principle according to structure of the present invention is, coin 20 and key 10 directly act on control profile 56A under the situation that does not have other intermediate structure parts, 56B or 57A, 57B, they convert the tangential movement of coin and key to according to the principle of dip plane the vertical movement of control assembly (functional part 50).Will emphasize again also that at this by the locking profile 58A above or below central plane ME-ME, 58B or 59 is at a

control profile

56A, 56B or 57A, 57B cause the mutual locking/release of other parts when loading; To this point be described by means of Fig. 3 and 4 now, they illustrate two height and position H1 and the H2 of functional part 50 when the coin 20 (Fig. 4) of the key 10 (Fig. 3) of locking or locking and (will point out this, hacures are not represented the cross section in these two accompanying drawings, but are used for functional part 50 and shell 40 and cover plate of outer casing 30 are made a distinction):

For at the described functional part 50 of the primary importance shown in Fig. 3 (key 10 be locked in Coin deposit lock the inside) at its first height and position H1 that lifts.The second locking profile 59 in this height and position key side is embedded into 11 the insides, corresponding space of key 10 and prevents to take out this key, and described for this reason functional part 50 is fixed on this top position by spring members 60 and boss 52.If now a coin 20 is injected Coin deposit lock on the direction of coin chamber 22, then this coin at first can pass through the locking profile 58A of coin side from the below of locking profile, 58B and at it along finally meeting the first control profile 56A that is arranged on longitudinal axes L-L both sides, 56B on the stroke in the Coin deposit lock surface level by its basal edge limit.When continuing to inject coin 20, owing to constitute the control profile 56A of dip plane according to the dip plane principle, 56B, and make the horizontal throw of coin 20 convert the vertical moving of functional part 50 to, promptly, described functional part 50 moves at the second lower height and position H2 shown in Fig. 4 from its first height and position H1 downwards, and again by the acting force support of volute spring (spring members 60), this volute spring just is being bearing in the top of boss 52 on the decline of this stroke.

Described functional part 50 drops to the second height and position H2 from the first height and position H1 and mainly has two effects:

Make the second locking profile 59 of key side from the space 11 of key 10, move out on the one hand, make and to pull out this key, make the first locking profile 58A of coin side on the other hand, 58B moves to the back at coin 20 edges in the function stroke of coin, the locking profile surrounds the position, rear end of coin pincerlikely in this function stroke, makes coin no longer can be drawn out.Described coin be inserted through itself and the first control profile 56A, the alternating action of 56B not only discharges key, and the locking coin.

Opposite process correspondingly is:

When making key 10 on the direction of key chamber 12 when mobile in the view at Fig. 4, then can make the so without a doubt key chamber of injecting of this key far awayly, collide the second control profile 57A of key side up to its front end side, 57B, and by aforesaid identical interaction, make key continuation in the horizontal direction advance the vertical stroke that causes functional part 50 to make progress, promptly turn back to the first height and position H1 again from the second height and position H2.This means, the first locking profile 58A of coin side, 58B discharges coin again, and second of the key side locking profile 59 is embedded into the space 11 of key 10 again and is locked simultaneously.

By can seeing in the cross-sectional view of height and position H2 of Fig. 5, the bottom surface of described functional part 50 tilts with a low-angle α with respect to the base plate 41 of shell 40.What the

first insurance profile

53A, 53B additionally were positioned at functional part 50 is used to hold the first guiding part 41A, the inside, space of 41B, and corresponding second on these insurance profiles and the cover plate of outer casing 30 insures profile 36A, 36B acting in conjunction.

At horizontal level shown in Figure 5, as two second control profile 57A that are arranged on longitudinal axes L-L both sides, by the side loaded of key the time, the effect that control assembly (functional part 50) is lifted for identical surface level is only played in the insertion of described key 10 (as mentioned above) to 57B simultaneously and with identical acting force.If not this situation (for example attempt operate situation) with a non-key object, then second control profile 57A, the non-homogeneous loading of 57B can not be played the height and position H1 that makes functional part be raised to desired release coin, but cause an effect of tumbling around angle [alpha], the result makes

corresponding insurance profile

36A, 36B or 53A, 53B are chimeric mutually, prevent that thus functional part 50 is raised to height and position H1.Guaranteed thus, when not using the system key of defined for this reason, can not take out coin.

The second embodiment explanation

By means of Fig. 6 to 14 second embodiment is described, wherein especially with reference to the stereographic map of Figure 12 to 14, they help understanding the working method of above-mentioned first embodiment, because the basic functional principle in two embodiment realizes that with being used to the essentially identical structure member of function is identical or approximate at least to a great extent, therefore also use identical Reference numeral for identical structure member or construction package.

Therefore the key distinction between first and second embodiment is only described below:

Fig. 6 corresponds essentially to the view of Fig. 1, and Fig. 7 is corresponding to Fig. 2.Especially (comparison diagram 2 and Fig. 7) as can be seen when latter two figures relatively, in a second embodiment, under the situation that version is similar to substantially or structure is identical of shell 40 and functional part 50, abandon spring members 60, and its function provides by the shape of a corresponding cover plate of outer casing 30, and this at first is described as follows:

One first scotch 34A (coin side) and one second scotch 34B (key side) are positioned on the base plate 31, constitute one first guiding channel 35A and one second guiding channel 35B (referring to Figure 14) betwixt.

The first spring-

latch

32A, 32B moves on the direction of longitudinal axes L-L in this guiding channel.The first spring-

latch

32A, 32B is loaded into its terminal location separately to coin and key.

Perpendicular to the first spring-latch 32A, the 32B second spring-latch 33A that is shaped, 33B, its leading section have a thickening body or profile, they insure and are fixed on its corresponding height and position H1 or the H2 with

corresponding boss

52A, 52B (seeing Fig. 9 and 11) acting in conjunction assurance function parts 50.

Different with first embodiment, the first control profile 55A also is set at 12 places, coin chamber, 55B, they arrive the first control profile 56A at coin, have played the effect that functional part 50 is descended before the 56B.

Described shell 40 has on its base plate 41 at the monosymmetric first guiding part 41A of longitudinal axis, 41B, add guiding space 42A therein, 42B, they are used to hold the guiding part 31A of cover plate of

outer casing

30,31B, the guiding part 41A of shell 40 wherein, 41B itself is fixed on the guiding space 51A of functional part 50, the 51B the inside, and this point is especially illustrated by the cross-sectional view of Fig. 9 and 11.

The major function of second embodiment corresponds essentially to above-mentioned function, corresponding to the Fig. 3 among first embodiment and Fig. 4, wherein especially expresses the function of the spring-latch that is formed in the first and second spring-latch forms on the cover plate of outer casing 30 at this Fig. 8 and Figure 10.

For being positioned at its latched position at the described key 10 of the first height and position H1 shown in Fig. 8 and 9 and on longitudinal axis, loading, so that guarantee to be on this position by spring-latch 32A.The height and position H1 of described functional part 50 obtains insurance (that is being lockable) thus,, makes described spring-latch 33A that is, and the bottom shape of 33B is from the beneath boss 52A that blocks on the

functional part

50,52B.

If inject a coin now, then this coin is by the

first control profile

55A, 55B and 56A, 56B plays and makes 50 fens two stages of functional part drop to the effect that it descends height and position H2 and discharges key 10, (Figure 11) described spring-latch 33A wherein, 33B slips over the boss 52A of control assembly (functional part 50) with shrinking, and 52B and opening again in its surface makes the height and position H2 below second insure (that is being lockable) thus.

Continuation among the height and position H2 of described key 10 below the functional part shown in Figure 10 and 11 50 imports the control profile 57A that passes through the second key side again, the effect that discharges coin 20 is played in the loading of 57B, and the space 11 that enters key 10 by the second locking profile 59 makes key 10 " self-locking ", thus by spring-latch 33A, the contraction of 33B makes them again at

boss

52A, 52B next door slip over and make they at the height and position H1 that is reached again from the beneath boss 52A that blocks, 52B.

Therefore, second embodiment is can make Coin deposit lock comprise that shell only is made of three structure members on the cover plate of outer casing 30 by elastic property is combined to, wherein with the advantage that first embodiment compares, especially for cover plate of outer casing 30, extrusion process can realize the processing of its economy.
