Abstract

Use of the flexible ropes (5) to connect common manipulative (30) with executive locking mechanisms (17,66) integrated in the display stands (1,61) for exposure of the eyeglasses (4) is performed in manner; that by the pulling (13) of the flexible ropes (5) from the side of common manipulative mechanism (30) executes to do simultaneously the closing (15,65) while due to the action of the return spring force (8,63) by the pulling on the opposite direction (12) are executes simultaneously opening (14,64) of executive locking mechanisms (17,66). By the using of the flexible ropes (5) as described, stable holding of the locking mechanisms (17,66) is achieved in the closed position, also in the cases of external force acting on the embracing hooks (2,60) aimed at forcing to opening (14,64) and so in that way exposed glasses (4) are protected against of unauthorized taking. Flexible ropes (5), in space between the common manipulative (30) and executive locking mechanisms (17,66), can be practically carried out in an arbitrary manner, without limitation in terms of length and spatial axis changes in implementation, so therefore their application opens wide possibilities in performances of exhibition stands and shelves, both in technical and in design sense.

Description

USING OF THE FLEXIBLE ROPES IN M ECHANISMS FOR PREVENTING OF UNAUTHORIZED TAKING OF THE EYEGLASSES FROM THE EXHIBITION STANDS AND EASELS

1. DESCRIPTION OF THE INVENTION

1.1. The area on which the invention relates

The invention relates to the application on static and dynamic exhibition stands and easels classified by the international patents classification (IPC); A47F 7/02 which are intended for exposing items such as; eyeglasses, wristwatches, jewelry and the like, and which are equipped with mechanical devices for the prevention of unauthorized taking, as stated in the international patent classification (IPC); A47F 7/024

1.2. Introductory note

For the purpose of simplicity, in the further description of the invention are used the following abbreviated expressions and terms;

Instead of the term; - 'device for preventing of unauthorized removal on display stands and easels', hereinafter referred is used the abbreviated term; - 'executive lock mechanism'.

Instead of the term; - ' exhibition stand for eyeglasses and other exposed items with embedded mechanism for preventing of unauthorized removal', hereinafter referred is used the abbreviated term; - 'exhibition stand'

The term "flexible rope" is hereinafter implies to as a simply flexible rope or flexible lane, and may also be a flexible fiber made of steel or other material which enables effective force transmission only in pulling direction between the two ends of that rope.

- -The term "bi-directionally flexible rope'¹ is hereinafter implies to as a simply flexible rope or flexible lane, and may also be a flexible fiber made of steel or other material which enables effective force transmission in both axial directions, i.e. in the direction of push and also in the pull direction, between the two ends of that rope. Such a type of ropes are also known by commercial names; Push-Pull cable or Push-Pull rope.

- The term "embracing hook" is hereinafter implies to as an executive mechanical element, which is an integral part of an executive lock mechanism, usually in the form of a reverse letter U or L, which partially embracing the exposed object on a suitable place in prevent purpose of unauthorized taking,

- The term 'manipulative mechanism', is hereinafter referred to as the general term which implies a manual or electromotive mechanical devices by means of which, indirectly, through flexible ropes, are managed in a controlled manner with an executive mechanism for preventing of unauthorized taken, and which are embedded in display stands and easels. 1.3. Technical problem which be solved by the invention

The primary goal by exhibiting the exposed items is that these items are physically immediately and visually more expressively presented, and therefore so it is important that their presentation be performed with the least necessary physical obstacles but also with the as possible least indirect visualy disturbances.

This is particularly demanding on the construction and physical dimmensions of display stands with integrated devices for preventing of unauthorized taking, because that stands have built-in mechanisms for preventing of unauthorized removal and therefore they are necessarily robust, and as such are also significantly bulky and unwieldy in compared with ordinary stands.

In addition, such stands have specific mechanical elements such as; hooks, latches, embracing rings or the like, which serve as a physical barrier to prevent of unauthorized taking, and as such that elements import greater or less disturbance in the visual presentation of the exposed subject.

Display stands used for display in shopping malls or specialty stores, anti-theft device mechanisms have built-in mechanical locks, and often with added manipulative handles or wheels, adapted for quick manipulation of exposed objects.

Since these locks, because of their simple and fast accessibility, are usually embedded on the front (forehead) side of the display stands, as such they also adversely affect, most often in the sense of secondary visual disturbance. lA.The state of the technique

Existing construction ways of devices to prevent of unauthorized taking of eyeglasses and eyeglasses frames on individual stands and easels are most commonly derived in a classical way, ie with a standard lock with a mechanical key and with manipulation mechanism which is integrated directly into the each stand or easel.

The advantage of this performance is that it allows some flexibility in terms of arbitrary physical deployment of multiple display stands on the same shelf, while disadvantage is because, due to their necessarily greater volume, which is the consequence of their built-in mechanisms and locks, such stands operate too dominant and often locks visually 'aggressive' in relation to the exposed object.

In addition to the previously mentioned embodiment, where the lock and manipulative mechanism are individually integrated into each stand or easel, there are also performances with a common manipulative mechanism, which simultaneously controls all executive devices for preventing of unauthorized removal, which are integrated in each exhibition stand set up on a common shelve.

The advantage of this kind of performance is that these exhibition stands, in comparison to the previous variant, can be made in considerably smaller physical dimensions, and since of that they are so aesthetically more suitable for exhibition use.

On the other hand, such a common manipulative mechanism is placed below the upper surface of the common shelf and consists of mechanical elements such as steel levers and / or rods, which makes it relatively rigid and does not allow virtually any possibility of subsequent arbitrary change of arrangement, number or type of exhibition stands on these shelves. The reason for that is because that exhibition stands with integrated devices for preventing of unauthorized taking should necessarily be placed in a strictly defined position against the construction of a common manipulative mechanism, so to enable to handle with them.

Furthermore, the construction of exhibition shelves with such mechanisms are most often derived in three levels; base, central part with the mechanism and with the cover plate and / or mask for covering the mechanism. For this reason, such shelves, besides being technologically demanding for producing and installing, are most often physically much thicker than the conventional single-layered, such as glass shelves or the like, which in design sense further limits their wider application. 1.5. Technical essence of the invention

The invention brings novelties in the construction of mechanisms in a manner; that so instead of the rigid elements like as levers or rods, with which by principle; push - pull, execute direct control with the mechanical elements for preventing of unauthorized taken, are used a flexible ropes in combination with or without return springs..

In variants with the return springs, this is derived in such a way; that one end of the flexible rope and the return spring are firmly jointed to the executive element for preventing of unauthorized taking, while the other end of the rope is linked to the dragging and lock mechanism, and the other end of the return spring is attached to the fixed part of the housing so as to provide a solid ground for deforming it.

By pulling a flexible rope it's done the closing of the mechanism for preventing of unauthorized taking, while simultaneously deforming the return spring.

When the end closing position is reached than the pulling of the flexible rope is stoped and executes it’s lock, thereby the mechanism for preventing of unauthorized taken firmly keeping in the closed position.

By mechanism disengaging is released the locked end of the flexible rope, which allows to release of the accumulated energy in the return spring, which was accumulated by its deformation in closing proces. The release of accumulated energy in the return spring is manifested by its return to the initial position, with which is indirectly caused the opening of a mechanism for preventing of unauthorized taking, which is physically conected with that return spring.

in the variants of mechanisms without return springs are used bi-directional flexible ropes, so-called Push-Pull ropes, where it is possible to apply force in both directions. The reason for this is that, besides the closing and stable holding in closed position, which occurs due to the effect of the withdrawal force, bi-directional flexible ropes can also transfer the force of pushing to allow the opening of an executive locking mechanism for preventing of unauthorized taking.

It is also important to note that the flexible rope, in the space between the manipulative and executive locking mechanism, may be carried out in an arbitrary manner and without any restriction that would are refered to its length and spatial change of direction in the axis of rope guiding, as well as the number how much times is that changes of direction done. The routing of the rope and its carried out, can be executed by means of; routing wheels, guiding tubes, axial rigid tubular sleeves, .... and with other similar standard elements.

Based on the previous one it can be concluded; that by using flexible ropes in mechanisms for preventing of unauthorized taking, embeded in the exhibition stands, it provides far greater flexibility in designing and constructing display stands and shelves than it was possible in so far known ways, in which rigid lever elements and / or rods are used, and which are generally set in exactly calculated ratio of its interactions, and which are executed for only one particular purpose.

1.7. Examples of possible practical applications of the invention

In the text that follows are described some examples of possible practical realization of the invention, with application on display stands and easels with built-in mechanism for preventing of unauthorized taken, which are used for exposure of eyeglasses and eyeglasses frames.

As executive elements that directly prevent of the unauthorized use of exposed glasses or glasses frames, the most commonly are used hooks, with rotating or linear motion, which are used to embracing the frame of the glasses in the narrow frontal part of the frame, ie at the frontal connection that connect the frames of the left and right lenses, so on that way to preventing of unauthorized taken.

Manipulative mechanisms, by means of which trough the flexible ropes acting on executive lock mechanisms, in principle can be derived as a simple mechanism with a classicmechanical lock and key, which are intended for manual control or as a more complex mechanism powered by electric motor, which is intended for remote control and monitoring.

1.7.1. An example of the use of flexible ropes to the mechanical connection in between of

eyeglasses display stands with built-in executive locking mechanisms with return springs and a common manipulative mechanism powered by electromotor

Description below is connected to the drawing; Fig. 1. An illustration of possible use of flexible ropes to the connections in between of executive locking mechanisms with return springs and common manipulative mechanism powered by electromotor.

On the horizontally placed shelf 18 are mounted two types of eyeglass holders : A - eyeglasses holder 1 with an embedded executive lock element 17, which consisting of a swivel embracing hook 2, rotatary shaft of the swivel embracing hook 3 and a spiral return spring 8, and B-eyeglasses holder 61 with an embedded executive lock element 66, which consisting of linear guided embracing hook 60, spiral return spring 63 and vertical guids 62.

Embracing hooks with return springs 2 and 60 are tightly mechanical connected 6 at one end of the flexible rope 5, while the other two ends of the flexible ropes 5 are connected 7 with the rotary spindle 20, of common electromotive manipulative mechanism 30.

The rotary spindle 20 is directly mechanical coupled to the output shaft 22 of an self-braked

electromotor-reducer 24, and these three elements are jointed to one unit, in a functional sense represent a common electromotive manipulative mechanism 30, through which indirectly over the flexible ropes 5, operate on executive locking mechanisms 17 and 66, which are embedded in the eyeglasses display holders 1 and 61. By winding 28 flexible rope 5 on the rotary spindle 20 it results in the withdrawal of the other end of the rope 6, which is firmly connected to the embracing hook 2 and respectively 60.

At the display stand 1, with incorporated swivel embracing hook 2 and spiral return spring 8, retraction of the respective flexible rope 5 leads to the rotation of the embracing hook 2 about the rotating shaft 3 in the closing direction 15, by simultaneously deforming the return spring 8, which is at one end 9 hitched on that hook, while the other end of the return spring 8 is attached to the fixed part of the housing 10, so as to provide a firm support for its controlled deformation.

At the display stand 61 with incorporated linear guided embracing hook 60, by pulling the flexible rope 5 is directly caused motion of the embracing hook 60 in the closure direction 72, by simultaneously deforming the reverting spring 63 which at one end is coupled 58 on the linear embracing hook 60, while the second end of the returng spring 63 is relied on the bottom of the vertical guide rail 62 so as to provide a firm support for its controlled deformation (tensioning).

When in the closure process, the nose top of the embracing hook 34 get in the recess for its seating 35, located at the corresponding display stand 1 or 61, the drive motor reducer 24 stops, thereby stopping the pulling of the flexible rope 5, which means that the closure process of the embracing hooks 2 and respectively 60 is co pleted.

In the closed position, the respective return springs 8 and 63 are in the state of the maximum accumulated potential energy, generated as a result of their deformation in the closing process, and as such act with the maximum withdrawal force 12, which tends to uncontrolled unwinding of the flexible ropes 5 from the rotary spindle 20.

Uncontrolled unwinding of the flexible rope 5 is however prevented due to the mechanical self-braked of the drive motor-reducer 24, so that's why the embracing hooks 2 and respectively 60 are firmly keeping in the closed position, and such position can be characterized as a locking in closed position.

Also, due of the mechanical self-braked of the drive motor-reducer 24, embracing hooks 2 and respectively 60 are remain locked in the closed position even in the case of an external uncontrolled action of force, which acts in the sense of their violent opening, thereby are preventing of an unauthorized taking of exposed objects 4.

By rotating the rotary spindle to the left 27, causes unwinding 12 of the flexible ropes 5 is effected, thereby allowing that the return springs 8 and 63 to be returned to the initial state, i.e. to the state which was preceding of their deformation before closure, and simultaneously with their return being opened; - the rotation of the swivel embracing hook 2 in the right direction 14, respectively, of the linear embracing hook 60 in the upward direction 74.

It is important in this example to see that the flexible ropes 5 in the space between the common manipulative and executive locking mechanisms 17 and 66 can be carried out in an arbitrary manner andwithout limitation in terms of length and spatial directional change of the axis of implementation, as well as the number of how much times that directional change of the axis of implementation is done. It can also be seen that the flexible ropes 5 could be instaled at very easy way; through the vertical holes 26 and transverse 25 slots, derived from the underside of the display shelf 18, while the routing of the ropes on the path of execution is effected by means with the routing wheels 11.

Remark:

This example gives only an illustrative view of the use of two different types of eyeglass holders on the same shelf, which is enabled by the use of flexible ropes, as the mechanical links between the common manipulative and executive locking mechanisms, while it is expected that in practice, due to more economical production, and a later and simpler maintenance, use only one type of exhibition holders on the same shelf, possibly combined in variants of different physical characteristics of the same type in terms of; taller or lower type or both. 1.7.2. An example of the use of bi-directional flexible ropes to the mechanical connection in between of eyeglasses display stands with built-in executive locking mechanisms without return sorinas and common manual manipulative mechanism

Description belowis connected to the drawing; Fig. 2. An illustration of possible use of bi-directional flexible ropes to the connections in between of executive locking mechanisms without revert springs and common manual manipulative mechanism.

On the horizontally placed shelf 18, are placed two types of eyeglass stands: A - eyeglass stand 75 with a built-in locking mechanism 77, which consists of swivel embracing hook 76, rotatary shaft of the swivel embracing hook 3 and rotary coupling 81, and B - eyeglass stand 69 with a built-in locking mechanism 78, which consists of linear guided embracing hook 60 and vertical guides 62.

The swivel embracing hook 76 is mechanically connected to one end of the corresponding bi-directional flexible rope 80 via rotary joint 81 to prevent the bending of the rope 80 at the jointing point, while the linear guided embracing hook 60 is firmly connected 6 to the one end of this bi-directional flexible rope 80. The other two ends of the flexible ropes 80 are connected via the rotary couplings 82, to the correspondingly belong to them swivel levers 83 of the common manipulative mechanism 90.

Rotary spindle 20, with the swivel levers 83, is directly mechanically coupled 94 to the rotor 93 of mechanical lock 91, with which is manipulated by mechanical key 93 by placing it in two fixed rotational positions; 95 - unlocked or 96 - locked, so that these elements are connected to a single unit, which in a functional sense constitute a common manual manipulation mechanism 90, through which indirectly, via bi-directional flexible ropes 80, are acting on executive locking mechanisms 77 and 78, which are incorporated in eyeglass holders 75 and respectively 61.

By rotating the mechanical lock 91 to the locked position 96, the rotary spindle 20 is rotated to the right 28, and in the same direction are moving rotating levers 83 which are firmly tied to it, and that causes the withdrawal 85 of the flexible ropes 80, which indirectly results with closing of the embracing hooks 76 and 60.

At the display stand 75, with the swivel embracing hook 76, withdrawal of appertain rope 80 caused to rotation of the embracing hook 76 around the rotating shaft of the rotary hook 3 in the closure direction 15, while at the display stand 69, with the built-in linear guided embracing hook 60, pulling of the appertain flexible rope 80 caused direct start to linear moving of the linear guid embracing hook 60 in the closure direction 65.

When in the closing process, the tops of the noses of embracing hooks 34 finish with the setting up in recess of their seat 35, which are placed on the appertain display stands 75 and 69, the withdrawal of the flexible rope 80 stops, which means that the closing process of the embracing hooks 76 and 60 is completed and that the mechanical lock is set to locked position 96.

By placing the mechanical lock 91 in the locked position 96, embracing hooks 76 and 60 remain locked in the closed position, even in the case of an external uncontrolled action of force, which acts in the sense of violent opening, thereby are preventing of an unauthorized taking of exposed objects 4,

By turning the mechanical lock 91 to the unlocked position 95 are turns the rotary spindle 20 to the left 27, and also in the same direction are moving swivel levers S3 which are firmly attached to it, which causes the pushing 84 of bi-directional flexible ropes 80, which indirectly has the consequence of the opening of embracing hooks; - the rotation of the swivel embracing hook 76 to the right rotation direction 14, respectively of the linear guided embracing hook 60 to the upward direction 64.

It is important in this example to see that the flexible ropes 80 in the space between the common manipulative and executive locking mechanisms 77 and 78 can be carried out in an arbitrary manner and without any limitations that would refer to its length and spatial direction change in the axis of rope guide, as well as the number of times that change of direction has been done. It can also be seen that the flexible ropes 80 could be instaled at very easy way; through the vertical holes 26 and transverse 25 slots, derived from the underside of the display shelf 18, while the routing of the ropes on the path of execution is effected by means with the tubular sleeves 16.

Remark:

Valid all as noted in the Remark description of the previous example.

1.7.3. An example of the use of flexible ropes for the mechanical connection between varying altitudes of eyeglasses display stands with common electromotive manipulative mechanism

Description below is connected to the drawings;

This example illustrates the possibility of an fairly practical application of simply flexible ropes 5 for the control with the locking mechanisms with swivel embracing hooks 2 and return springs 8, integrated in exhibition stands for eyeglasses 4, which by type are identical but with different heights; - low 1 and tall 31.

A detailed description of the functioning of this mechanisms, which is is given in the description; 1.7.1. An example of the use of flexible ropes to the mechanical connection in between of eyeglasses display stands with built-in executive locking mechanisms with return springs and a common manipulative mechanism powered by electromotor, is fully valid for both type of exhibition stands; low 1 and high 31.

From Fig. 3. it is apparent that between the low 1 and the high 31 display stands is the only difference in their height, and in that because on the rear of the taller stand 31 should be mounted eyeglasses handle holders 32, in order to exposed eyeglasses 4 could be placed in the proper position for its exposure. Ail other elements of the locking and execution mechanism, as well as the way of guiding the flexible ropes 5, and their routing through the routing wheels 11, are derived in the same way for both exhibition stands 1 and 31.

Figure 4 shows an example of a possible layout with four low 1 and four tall 31 display stands, placed in two parallel lines; frontal low 1, and behind them tall 31 exhibition stands, located on the same exhibition shelf 18. This drawing primarily seeks to show that conducting and routing of flexible ropes 5 for the purpose of linking the executive locking mechanisms of display stands 1 and 31 with the common electromotive mechanism 30 may be performed in various ways.

The executive locking mechanisms of the tall stands 31 are connected directly by the flexible ropes 5 with the rotary spindle 20 of a common manipulative mechanism 30, while the flexible ropes 5 for conecting two executive locking mechanisms of the low display stands 1 are guided by the routing wheels 11 - the left side of the shelf 18, and the other two low display stands 1, with the flexible tubular sleeves 16 - the right side of the shelf 18.

On Fig. 5. is shown frontal view of the exhibition shelf 18, on which are arranged the low 1 and tall 31 exhibition stands in the manner described above, where it is apparent that by exposure in to two horizontal lines the exhibition capacity of the given shelves 18 is being doubled, which is a very important characteristic for exposition in shopping malls and optical equipment stores. Also, it is still important to note that tall and low display stands can be made in according to the same principle with other types of mechanism and shapes of embracing hooks, and that they can be used in an analogous manner as previously mentioned in this example.

As well, except as illustrated in this example the use of a common manipulative mechanism with electromotive drive 30, for the same purpose also may be used a manual mechanism 90, or any another, by means of which indirectly, via flexible ropes 5, enables control with executive locking mechanisms in a functionally equivalent manner.

Remark:

On Fig. 3 and Fig. 4. with broken lines is symbolical marked vertically positioned mask 33 which is extending across the entire width of the exhibition shelf 18, which has no particular functional purpose but serves only as a physical barrier to prevent access to the manipulative mechanism 30 and also serves for visually separating the exhibition from background technical part of exhibition shelf 18.

1.7.4. An example of the use of flexible ropes on the mechanical connection of display stands mounted on rotary disks for dynamic presentation of exposed eyeglasses and common electromotive manipulative mechanism

Description below is connected to the drawings;

Fig.6. An illustration of the possible use of flexible ropes for connecting display stands mounted on rotating disks for dynamic presentation of exposed eyeglasses and and common manipulative mechanism powered by electromotor - side view

On Fig. 6. in a lateral view with a cross section is shown an example of a possible mechanism for dynamical presenting the esposed eyeglasses 4, which is enabled by the use of flexible ropes 5, and the presentation of the esposed eyeglasses 4 is carried out by repeated changing direction of rotation of the rotary disc 40 for an angle of +/- 90 ° in relation to the set start position.

Mechanism for dynamic presentation of exposed glasses 4, consists of; rotatable disc 40 which is mounted on the hollow shaft of the rotating disk 41, supported by the axial bearing 42 which is mounted on the carrying rack of the exibition shelf 47.

Rotation of the rotary disc 40, around the vertical axis 44, in both rotational directions 46, with the limitation of the angle of rotation from the central axis 43, is powered by motor-reducer 50 and a pair of pulleys; pulley 52, which is secured to the output shaft 51 of the motor-reducer 50, and the pulley 54, fixed to the hollow shaft of the rotating disk 41.

Both of these pulleys 52 and 54, as well as all other pulleys 54 which are fixed to the hollow shafts of the rotating disks 41, and which are arranged on the common carrying rack of the exibition shelf 47, are coupled via a common toothed belt 53, and so thereby is ensuring the synchronous guidance of all rotary disks 40 on that shelf.

Operation of the executive locking mechanism, which is integrated in the exhibition stand 1, as well as its connection with the flexible rope 5 with the common electromotive manipulative mechanism 30, fully corresponds with the description in; 1.7.1. An example of the use of flexible ropes to the mechanical connection in between of eyeglasses display stands with built-in executive locking mechanisms with return springs and a common manipulative mechanism powered by electromotor. The only difference is in the routing of a flexible rope 5, which in this case is routed through the three turning wheels 11.

As rotation of the rotary disc 40 is performed alternately by +/- ⁹⁰ ° ⁱⁿ both rotational directions 46 from the set start position, this rotation further results in the partial twisting and untwisting of the flexible rope 5 in the part passing between the rotating wheels 11 and which lie in the central axis of rotation 44. Therefore, exce t for the rotation angle limitation 43, it is necessary select flexible rope 5, with corresponding characteristics, so that these partial strain due to longitudinal twisting / untwisting 45 remain within elastic deformation limits, and at that way ensure long lasting and reliable operation of mechanism for eyeglasses dynamic presentation 4.

On Fig. 7. in frontal view is presented an example of a possible arrangement of four mechanical devices for the dynamic presentation of the exposed eyeglasses 4 on the display stands 1, which are mounted on the rotating disks 40.

The complete mechanism, including the electric motor-reducer 50, for to rotate the shaft of rotating disk 41, and thus the rotary plate 40, as well as the common electromotive manipulation mechanism 30, for controlling the executive locking elements of the stands 1, are located below of the exebition shelf carrying rack 47, which together with the associated case 48, make an exhibition shelf. l.S.Aapplication modes of the invention

The invention may be applied to the construction of separate exhibition shelves, on where can be an arbitrary number of eyeglasses display stands been installed, with built-in anti-theft manipulation mechanisms and a common manipulative mechanism, and so as thus constituting one complete functional and separate entirety.

Since such shelves are complete with all the elements capable of achieving complete function in terms of controlled manipulation with executive locking elements, they can be mounted independently on an exhibition panel, or by a modular principle can be placed within a single frame, designed to

accommodate several such shelves, which as a so constructed whole represent an exhibition display rack (or presenter - also often called).

Depending on the type of manipulation mechanism, also are possible different ways of control with them, in principle, for manually operated with the manipulative mechanisms, the most commonly used way is to install a single mechanical lock on each shelf, and that manipulation itself is carried out using the appropriate mechanical key, or eventually with the help of an additional manipulative lever or wheel.

In the case of use common manipulative mechanisms powered by electromotors, the control capabilities are far greater, and so are possible different control modes, such as, for example; singularly control with each shelf separately, or at once with all the shelves in one display rack, with remote or direct control, with or without option of automatic closing after a certain period of time, with signaling sound and / or light for indicating status of working state or alarm, etc., .

Using of the flexible ropes, flexible belts or flexible fibers made of steel or some other material (5), their mechanical connection (6, 7) between a common manipulative mechanism (BO) and executive locking mechanisms for preventing of unauthorized taking (17, 66), which are assembled from embracing hooks (2, 60) and appurtenant return springs (8, 63) and other auxiliary elements, and as such integrated in the display stands (1, 61) for exposing the eyeglasses (4), characterized by that, so by the pulling (13) of the flexible ropes (5) by means of a common manipulative mechanism (30), executes to do the closing (15, 65) of the embracing hooks (2, 60) around the exposed eyeglasses (4) placed on the display stands (1, 61) by simultaneously deforming of the appurtenantes return springs (8, 63) which manifests by the accumulation of potential energy in these springs.

2. Using in according to requirement 1, characterized by that, so by the releasing of the flexible ropes (5) by the common manipulative mechanism (30) is enable to release the energy accumulated in the appurtenant return springs (8, 63), what is manifested by the returning of the return springs (8, 63) to the state which was preceded of their deformation, and which indirectly leads to do the opening (14, 64) of the appurtenant embracing hooks (2, 60) which are firmly physically jointed (9, 58) with these return springs (8, 63).

3. Using in according to requirement 1, characterized by that, so by means of a common

manipulative mechanism (30) which is stopped in a firmly locked position (24) disable withdrawal (12) of flexible rope (5) from the side of appurtenant executive locking mechanism (17, 66) and thus preventing its opening in cases of external force acting on the embracing hooks (2, 60) which is aimed at the purpose of their forced and unauthorized opening (14, 64).

4. Using of the bi-directional flexible ropes, flexible belts or flexible flexible fibers made of steel or some other material (80) by which is possible effective transmission of force; in push direction (84) and in pull direction (85) in the application of the mechanical connection (81, 82 and 6, 82) between the common manipulative mechanism (90) and the executive locking mechanisms for preventing of unauthorized taking (77, 78) which are assembled from embracing hooks (76, 60) and other auxiliary elements, and as such integrated in the display stands (75, 69) for exposing the eyeglasses (4), characterized by that, so by the pulling (85) of the bi-directional flexible ropes (80) by means of a common manipulative mechanism (90) executes to do the closing (15, 65) of the embracing hooks (76, 60) around the exposed eyeglasses (4) placed on the display stands (75, 69).

5. Using in according to the requirement 4, characterized by that, so by the pushing (84) of the bidirectional flexible ropes (80) by means of a common manipulative mechanism (90), execute to do the opening (14, 64) of the embracing hooks (76, 60) around the exposed eyeglasses (4) placed on the display stands (75, 69).

6. Using in according to the requirement 4, characterized by that, by means of a common

manipulative mechanism (90) which is stopped in a firmly locked position (96) disable withdrawal (84) of bi-directional flexible rope (80) from the side of appurtenant executive locking mechanism (77, 78) and at that way are preventing their opening in cases of external force acting on the embracing hooks (76, 60) which is aimed at the purpose of their forced and unauthorized opening (14, 64).
