Introductory note

For the sake of simplification, in the further text of the description of the invention, the following abbreviated terms and concepts are used;

- Instead of the term; - 'device to prevent unauthorized taking on exhibition stands and pedestals' in the further text of the description, the abbreviated term is used; - 'executable locking mechanism'.

- Instead of the term; - "stand for displaying glasses and other exposed objects with built-in devices to prevent unauthorized taking" in the further text of the description, the abbreviated term is used; - 'exhibition stand'

- In the following text, the term 'flexible rope' refers to an ordinary flexible rope or a flexible strip, and it can also be a flexible thread made of steel or some other material, which enables the effective transmission of force only in the direction of pulling between two clamped ends rope.

- In the following text, the term "bidirectional flexible rope" means a flexible rope or a flexible strip, and it can also be a flexible thread made of steel or some other material, which is used in both axial directions, i.e. in the direction of pushing and also and in the direction of pulling, enables the efficient transfer of force between the two clamped ends of that rope. This type of rope is also known by commercial names; Push-Pull rope or Push-Pull cable.

- In the following text, the term 'comprehensive hook' refers to an executive mechanical element, which is an integral part of an executive locking mechanism, most often in the form of an inverted letter U or L, which partially covers the exposed object in a suitable place, with the purpose of preventing it from being taken by unauthorized persons .

- The term 'manipulative mechanism' in the following text, in a general sense, means a manual or electromotive mechanical assembly, which indirectly, via flexible ropes, controls the executive mechanism of devices to prevent unauthorized taking, installed on exhibition stands and pedestals, in a controlled manner.

A technical problem that is solved by an invention

The primary goal when exhibiting exhibited objects is that these objects are presented physically directly and visually as expressively as possible, so it is important that their presentation be performed with as few necessary physical obstacles as possible, but also with as few indirect, secondary visual distractions as possible.

This is particularly demanding on the construction and physical performance of exhibition stands with integrated devices to prevent unauthorized taking, because such stands, due to the built-in mechanisms to prevent unauthorized taking, necessarily have a more robust physical performance and as such appear significantly more clumsy compared to ordinary storage stands .

In addition, specific mechanical elements are installed on such stands, such as; hooks, latches, encompassing rings or the like, which serve as a physical barrier to prevent unauthorized taking, and as such introduce a greater or lesser disturbance in the visual presentation of the object on display.

In the case of exhibition stands used for display in shopping centers or special stores, the mechanisms of the devices to prevent unauthorized taking have built-in mechanical locks, and often also manipulative levers or wheels adapted for quick manipulation of the exhibited objects. Since these locks, for reasons of simple and quick availability, are most often installed on the front (front) side of exhibition stands, they also have an unfavorable effect as such, most often in terms of secondary visual distraction.

State of the art

Existing methods of performing devices to prevent unauthorized taking of glasses and eyeglass frames, on individual exhibition stands and stands, are most often performed in a classic way, i.e. with a standard lock with a mechanical key and a manipulative mechanism integrated directly into each exhibition stand or support.

The advantage of this design is that it enables a certain flexibility in terms of the arbitrary physical arrangement of several exhibition stands on the same shelf, while their disadvantage is that due to their necessarily larger volume, resulting from the mechanisms and locks built into them, such stands act too dominant and often visually 'aggressive' in relation to the object on display.

In addition to the aforementioned version, in which the locking and manipulative mechanism are individually integrated in each exhibition stand or stand, there are also versions with a common manipulative mechanism, which simultaneously controls all executive devices to prevent unauthorized taking, integrated in each exhibition stand placed on a common shelf.

The advantage of this design is that, compared to the previous variant, these exhibition stands can be made in variants with significantly smaller physical dimensions, and therefore, from an aesthetic point of view, they are much more suitable for exhibition use.

On the other hand, such a common manipulative mechanism is placed under the upper surface of the common shelf, and consists of mechanical elements such as steel levers and/or rods, which is why it is relatively rigid and does not allow practically any possibility in terms of subsequent arbitrary change of arrangement , number or type of display racks on those shelves. The reason for this is that exhibition stands with an integrated device to prevent unauthorized taking must necessarily be placed in a strictly defined position against the construction of the common manipulative mechanism, in order to enable their management.

Furthermore, the construction of exhibition shelves with such mechanisms is usually carried out in three levels; a stand, a central part with a mechanism and a cover plate and/or mask to cover the mechanism. That is why such shelves, apart from being technologically demanding to manufacture and assemble, are usually physically much thicker compared to common single-layer ones, such as glass or the like, which further limits their wider application in terms of design.

Technical essence of the invention

The invention introduces a novelty in the construction of mechanisms in the way; so that instead of rigid lever elements or rods, which are directly controlled by the push-pull principle on executive elements to prevent unauthorized taking, flexible ropes are used in combination with or without return springs.

In spring-return variants, this is done in such a way that one end of the flexible cord and the return spring are firmly physically connected to the anti-tampering actuator, while the other end of the cord is attached to the pull and lock mechanism and the other end to the return spring. the spring is attached to the fixed part of the housing, so as to provide a firm support for its deformation.

By pulling the flexible rope, the executive mechanism is closed to prevent unauthorized taking, while at the same time deforming (tensioning) the return spring.

Upon reaching the closed position, the pull of the flexible rope is stopped and it is locked, which keeps the anti-tamper mechanism firmly in the closed position.

By unlocking the mechanism, the locked end of the flexible rope is released, which enables the release of the energy accumulated in the return spring, caused as a result of its deformation during closing. The release of the accumulated energy in the return spring is manifested by its return to the initial position, which indirectly leads to the opening of the mechanism to prevent unauthorized taking, which is physically connected to this spring.

In the version of mechanisms without return springs, two-way flexible ropes are used, so-called. Push-Pull cables, where force can be applied in both directions. The reason for this is that in addition to the closing and stable holding in the closed state, which is the action of the pulling force, it is necessary that these flexible ropes can also transmit the pushing force, in order to be able to open the executive mechanism to prevent unauthorized taking.

It is important to note here that the flexible rope, in the space between the manipulative and executive locking mechanism, can be implemented in an arbitrary manner and without any restrictions related to its length and spatial changes in the direction of the axis of the rope guidance, as well as the number of times this change occurs direction done. Only the routing of the rope, i.e. its routing, can be performed using; turning wheels, conductive tubes, axially rigid bushings,.... and similar standard elements.

Based on the above, it can be concluded; that the use of flexible ropes in anti-tampering mechanisms on exhibition stands allows far greater flexibility in the design and construction of exhibition stands and shelves than was possible in previously known ways, where rigid lever elements and/or rods were used , which are mostly set in precisely calculated interaction ratios, performed only for a specific purpose.

Examples of possible practical realizations of the invention

The description that follows presents some examples of possible practical realizations of the invention, with application to exhibition stands and pedestals, with built-in mechanisms to prevent unauthorized taking, which serve to display glasses and glasses frames.

As executive elements, which directly prevent the unauthorized taking of exposed glasses or glasses frames, hooks are most often used, with a rotary or linear encompassing movement, by means of which, in the closed state, the glasses frame is captured in the narrowest frontal part of the frame, i.e. in the place of the frontal connector that joins the frames for installing the left and right lenses, so that their unauthorized removal is impossible.

Manipulative mechanisms, by means of which flexible ropes are used to act on the executive locking mechanism, can in principle be executed as simple mechanical ones, with a classic lock and key, intended for manual control, or electric ones, which enable remote control and monitoring.

An example of the application of flexible ropes on the mechanical connection of glasses display stands, with built-in executive locking mechanisms with return springs and a common electric motor manipulative mechanism

The description that follows is related to the drawing shown on; Sl. 1. Presentation of the possible application of flexible ropes on the connection of executive locking mechanisms with return springs with a common electric motor manipulative mechanism

On the horizontally placed shelf 18, two types of eyeglass holders are placed: A - eyeglass holder 1 with built-in executive locking element 17, which consists of a rotary hook 2, a pivot shaft of the rotary hook 3 and a spiral return spring 8, and B - an eyeglass holder 61 with a built-in executive locking element 66, which consists of a linearly guided encompassing hook 60, a pressure return spring 63 and a vertical guide 62.

The comprehensive hooks with return springs 2 and 60 are firmly mechanically connected to one end 6 of the associated flexible rope 5, while the other two ends 7 of the flexible ropes 5 are attached to the winding spindle 20 of the common electromotive manipulative mechanism 30.

The rotary spindle 20 is directly mechanically connected 21 to the output shaft 22 of the electric motor-driven self-braking reducer 24, so these three elements connected into one unit, in the functional sense, represent a common electromotor manipulative mechanism 30, by means of which, indirectly, via flexible ropes 5, the control acts on executive locking mechanisms 17 and 66, built into eyeglass holders 1 and 61.

By winding 28 of the flexible rope 5 on the rotary spindle 20, it results in the pulling 13 of the other end of that rope 6, to which the corresponding encompassing hook 2 or 60 is firmly attached.

In the case of the exhibition stand 1, with a built-in swivel hook 2 and a spiral return spring 8, pulling the associated rope 5 leads to the rotation of the encompassing hook 2 around the pivot axis of the rotary hook 3 in the direction of closure 15, while at the same time deforming the spiral return spring 8, which is tied at one end 9 on that encompassing 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 (tensioning).

In the case of the exhibition stand 61 with a built-in linear enclosing hook 60, pulling the flexible cord 5 leads to the direct movement of the enclosing hook 60 in the direction of closing 72 while at the same time deforming the compression return spring 63, which rests on the enclosing hook 60 with one end 58, while the other end of the return the spring 63 rests against the bottom of the vertical guide 62, so as to provide a firm support for its controlled deformation (tensioning).

When, in the process of closing, the top of the carrier of the encompassing hook 34 is in the bed for its attachment 35, on the corresponding exhibition stand 1, i.e. 61, the drive motor-reducer 24 stops, which also stops the pulling of the flexible rope 5, which means that the process closing of encompassing hooks 2 or 60 completed.

In the closed position, the associated return springs 8 and 63, respectively, are in a state of maximum accumulated potential energy, resulting from their deformation during the closing process, and as such they act with a maximum return pulling force 12, which tends to uncontrollably unwind the flexible rope 5 from the rotating spindle 20.

Uncontrolled unwinding of the flexible rope 5 is however prevented due to the mechanical self-braking of the drive motor-reducer 24, so thanks to this the encompassing hooks 2 and 60 are firmly held in the closed position, and such their position can be characterized as their locking in the closed position.

Also, due to the self-braking of the drive motor-reducer 24, the encompassing hooks 2 and 60, respectively, remain 'locked' in the closed position even in the event of an external uncontrolled force acting in the sense of their violent opening, thus preventing unauthorized taking of exposed objects. 4.

By turning the rotary spindle to the left 27, the 12 flexible ropes 5 are unwound, which enables the return of the associated return springs 8 and 63 to their initial state, i.e. to the state that preceded their deformation before closing, and simultaneously with their return, the opening is also performed; - rotary encompassing hooks 2 in the right direction of rotation 14, i.e. linear encompassing hooks 60 in the upward direction 74.

In this example, it is important to note that the flexible rope 5, in the space between the common manipulative and executive locking mechanisms 17 and 66, can be carried out in an arbitrary way and without any restrictions related to its length and spatial changes of direction in the axis of the rope guidance, as well as the number of times that change of direction was made. It can also be observed that the routing of the flexible ropes 5 is very simple; through vertical holes 26 and transverse slots 25, made from the lower side of the display shelf 18, while the routing of the ropes in the path of the execution is made by means of turning wheels 11.

Remark:

This example is only an illustrative representation of the possibility of using two different types of eyeglass holders on the same shelf, which is made possible by the use of flexible ropes, as mechanical connections between the common manipulative and executive locking mechanisms, while it is to be expected that in practice, for reasons of more economical production , and later and simpler maintenance, use only one type of display holders on the same shelf, possibly in combination in variants of different physical versions of the same type in the sense; higher or lower or both.

An example of the application of two-way flexible ropes on the mechanical connection of glasses display stands, with built-in executive locking mechanisms without return springs and a common manual manipulative mechanism

The description that follows is related to the drawing shown on; Fig. 2. Presentation of the possible application of two-way flexible ropes on the connection of executive locking mechanisms without return springs with a common manual manipulative mechanism

On the horizontally placed shelf 18, two types of eyeglass holders are placed: A - an eyeglass holder 75 with a built-in executive locking element 77, which consists of a rotating hook 76, a rotating shaft of the rotary hook 3 and a rotating coupling 81 and B - an eyeglass holder 69 with built-in executive locking element 78, which consists of a linearly guided encompassing hook 60 and a vertical guide 62.

The rotary enclosing hook 76 is mechanically connected to one end of the associated bidirectional flexible rope 80, via a swivel joint 81, to prevent the rope from buckling at the connection point, while the linear enclosing hook 60 is firmly attached 6 to one end of the associated bidirectional flexible rope 80. The other two ends of the flexible ropes 80 are connected via swivel couplings 82 to the corresponding swivel levers 83 of the common manipulative mechanism 90.

The rotary spindle 20, with pivoting levers 83, is directly mechanically connected 94 to the rotor 93 of the mechanical lock 91, which is controlled by means of the associated mechanical key 93 by placing it in two fixed pivoting positions; 95 – unlocked and 96 – locked, so that these elements connected into one unit, in the functional sense, represent a common manual manipulative mechanism 90, by means of which indirectly, via two-way flexible ropes 80, the control acts on the executive locking mechanisms 77 and 78, built in glasses holders 75 and 61 respectively.

By rotating the mechanical lock 91 towards the locked position 96, the rotary spindle 20 is also rotated to the right 28, i.e. the pivot levers 83 which are firmly connected to it are also rotated in the same direction, which causes the flexible ropes 80 to pull 85, which indirectly results in closing of encompassing hooks 76 and 60.

In the case of the exhibition stand 75, with a built-in swivel hook 76, pulling the associated rope 80 leads to the rotation of the encompassing hook 76 around the pivot axis of the rotary hook 3 in the direction of closing 15, while in the case of the exhibition stand 69 with a built-in linear encompassing hook 60, pulling the associated flexible rope 80 leads until the direct start of the encompassing hook 60 in the direction of closing 65.

When, in the process of closing, the tips of the supports of the encompassing hooks 34 are in the beds for its attachment 35, on the corresponding exhibition stand 75 or 69, the pulling of the flexible rope 80 stops, which means that the process of closing the encompassing hooks 76 and 60 is completed, and that is a mechanical lock placed in the locked position 96.

By placing the mechanical lock 91 in the locked position 96, the encompassing hooks 76 and 60 remain "locked" in the closed position even in the event of external uncontrolled force in the sense of their violent opening, thus preventing unauthorized taking of exposed objects 4.

By rotating the mechanical lock 91 towards the unlocked position 95, the rotary spindle 20 is also rotated to the left 27, i.e. the pivot levers 83 which are firmly connected to it are also rotated in the same direction, due to which the two-way flexible ropes 80 are pushed 84, which indirectly has as a result of the opening of the encompassing hooks; - rotary encompassing hooks 76 in the right direction of rotation 14, i.e. linear encompassing hooks 60 in the upward direction 64.

In this example, it is important to note that the flexible rope 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 restrictions related to its length and spatial changes of direction in the axis of the rope guidance, as well as the number of times that change of direction was made. It can also be observed that the routing of the flexible ropes 80 is very simple; through vertical holes 26 and transverse slots 25, made from the lower side of the display shelf 18, while the routing of the ropes in the way of the conduction is made using bushings for guiding the flexible ropes 16.

Remark:

Everything stated in the description note of the previous example is valid.

An example of the application of flexible ropes to connect exhibition stands of different heights and a common electric motor manipulative mechanism

The description that follows is related to the drawings shown in the pictures;

Sl. 3. Presentation of the possible application of flexible ropes to connect exhibition stands of different heights and a common electromotive manipulative mechanism - side view

Sl. 4. Presentation of the possible application of flexible ropes to connect exhibition stands of different heights and a common electromotive manipulative mechanism - top view

Sl. 5. Presentation of the possible application of flexible ropes to connect exhibition stands of different heights and a common electromotive manipulative mechanism - front view

This example shows the possibility of a very certain practical application of ordinary flexible ropes 5 with the management of executive locking mechanisms with rotary encompassing hooks 2 and return springs 8, integrated in exhibition stands for displaying glasses 4, which are identical in type, but of different heights in execution; - low 1 and high 31.

A detailed description of the functioning of such mechanisms is given in the description; 1.7.1 An example of the application of flexible ropes on the mechanical connection of the executive locking mechanisms with the return springs of the glasses display racks and the common electric motor manipulative mechanism, and is fully valid, both for the low 1 and for the high 31 exhibition racks.

From Fig. 3. it is visible that between the low 1 and the high 31 exhibition stand, the only difference is in their height, and that in the case of the high exhibition stand 31, it is necessary to add holders for the handles of the glasses 32 on the back side, so that the displayed glasses 4 can be placed in the correct position for their presentation. All other elements of the locking and executive mechanism, as well as the way of guiding the flexible ropes 5, and their direction via the turning wheels 11, were performed in an identical way for both exhibition stands 1 and 31.

Fig. 4 shows an example of a possible arrangement with four low 1 and four high 31 exhibition stands, which are placed in two parallel rows; in front, low 1, and in the back, high 31 exhibition stands, placed on the same exhibition shelf 18. The purpose of this drawing is primarily to show that the routing or routing of the flexible ropes 5 connecting the executive locking mechanisms of the exhibition stands 1 and 31 and the common electric motor mechanism 30 can be performed in different ways.

The executive locking mechanisms of the high racks 31 are connected directly, by means of the corresponding flexible ropes 5, to the rotary spindle 20 of the common manipulative mechanism 30, while the flexible ropes 5, for connecting the two executive locking mechanisms of the low exhibition stands 1, are directed by means of turning wheels 11 - the left side of the shelf 18, and the other two low exhibition stands 1, using flexible bushings 16 - the right side of the shelf 18.

On Fig. 5. A frontal view of the exhibition shelf 18 is shown, on which the low 1 and high 31 exhibition stands are arranged in the previously described manner, where it is visible that the display in two horizontal rows floods the exhibition capacity of the given shelf 18, which is a very important characteristic for display in shopping centers and optical equipment stores.

Here it is also important to note that, according to the same principle, it is possible to produce high and low exhibition holders for glasses with other types of mechanisms and forms of executive encompassing hooks, and that they can also be used in an analogous way, as stated in this example. .

Likewise, in addition to the use of a common manipulative with electric motor guidance 30 as shown in this example, a manual mechanism 90, or another, can be used for the same purpose, by means of which, via flexible ropes 5, it is possible to control executive locking mechanisms on functionally equivalent way.

Remark:

On Fig. 3 and Fig. 4. only the vertically positioned mask 33, which stretches across the entire width of the exhibition shelf 18, is drawn, and which does not have a special functional purpose, but serves only as a physical barrier to access to the manipulative mechanism 30, and also serves to visually separate the exhibition from of the background, technical part of the exhibition shelf 18.

An example of the application of flexible ropes to connect exhibition stands placed on rotating discs for dynamic presentation of exhibited glasses and a common electric motor manipulative mechanism

The description that follows is related to the drawings shown in the pictures;

Fig. 6. Illustration of the possible application of flexible ropes to connect exhibition stands placed on rotating discs for the dynamic presentation of exhibited glasses and a common electromotive manipulative mechanism - side view

Fig. 7. Illustration of the possible application of flexible ropes to connect exhibition stands placed on rotating discs for dynamic presentation of exhibited glasses and a common electric motor manipulative mechanism - front view

On Fig. 6. in a side view with a section, an example of a possible implementation of the mechanism for the dynamic presentation of glasses 4 is shown, which is made possible by the use of flexible ropes 5, and the presentation of the exposed glasses 4 takes place by repeatedly turning and returning the rotary disc 40, for an angle of +/ - 90° from the set starting position.

The mechanism for dynamic presentation of exposed glasses 4, consists of; of the rotary disk 40, placed on the rotor of the rotary disk 41, which rests on the support base of the exhibition shelf 47 via the axial bearing 42.

Rotation of the rotary disk 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 made possible by means of a motor-reducer 50 and a pair of pulleys; pulleys 52, fixed to the output shaft 51 of the motor-reducer 50 and pulleys 54, fixed to the rotor of the rotating disc 41.

Both of these pulleys 52 and 54, as well as all other pulleys 54, fixed to the rotors of the other rotary disks 41, placed on the common supporting base of the exhibition shelf 47, are connected via a common belt 53, which ensures the synchronous guidance of all the rotary disks 40, on that to the shelf.

The functioning of the executive locking mechanism, integrated in the exhibition stand 1, as well as its connection by means of a flexible rope 5 with the common electric motor manipulative mechanism 30, fully corresponds to that described in ; 1.7.1 Example of the application of flexible ropes on the mechanical connection of executive locking mechanisms with return springs of glasses display stands and a common electric motor manipulative mechanism

The only difference is in the routing of the flexible rope 5, which in this case is directed over three turning wheels 11.

Since the rotation of the rotary disk 40 is performed alternately by +/-90° in both rotational directions 46 from the set start position, this rotation results in an additional partial unwinding or twisting 45 of the flexible rope 5, in the part that passes between the turning wheels 11, and which lies in the central axis of rotation 44. For this reason, in addition to the limitation of the angle of rotation 43, it is necessary for this purpose to select a flexible rope 5, with suitable characteristics, so that this partial unwinding or twisting 45 remains within the limits of elastic deformations, and thus ensures long-term and reliable operation mechanism for dynamic presentation of glasses 4.

On Fig. 7. in the front view, an example of a possible arrangement of four mechanical devices for the dynamic presentation of the exhibited glasses 4, placed on the exhibition stands 1, which are located on the rotating discs 40, is shown.

The complete mechanism, including the associated motor-reducer 50, for turning the rotor of the rotary disk 41, and thus the rotary plate 40, as well as the common electromotor manipulative mechanism 30, for managing the executive locking elements of the rack 1, are located under the support base of the exhibition shelf 47, which, together with the corresponding case 48, forms an exhibition shelf.

Method of application of the invention

The invention can be applied for the construction of separate exhibition shelves, on which an arbitrary number of exhibition stands for displaying glasses are placed, with built-in mechanisms to prevent unauthorized taking and a common manipulative mechanism, so as such it represents one, functionally complete unit.

Since these shelves are complete with all the elements that make it possible to achieve a complete function in the sense of controlled manipulation with executive locking elements, they can be installed independently on an exhibition wall, or according to the modular principle, they can be placed inside a single frame, made to accept several such shelves, which as such, they represent one exhibition display (or presenter - a common name).

Depending on the type of manipulative mechanism, it is also possible to implement different management methods. In principle, for manually controlled manipulative mechanisms, the most common method will be to install one mechanical lock on each shelf, and the manipulation itself is performed using a suitable mechanical key, or possibly with the help of some kind of additional manipulative handle or wheel.

With electromotive manipulative mechanisms, the control possibilities are much greater, so it is possible to perform with different control methods, such as, for example, independent control with each shelf separately, or with all shelves at one exhibition display, with remote or direct control, with or without an option automatic closing after the expiration of a certain time, with sound and/or light notification of the working state or alarm and the like,…….
