It is distinguished by the integration of a variable drawer mechanism and analog sliders, thus offering greater flexibility and security compared to traditional combination locking devices. TECHNOLOGICAL BACKGROUND OF THE INVENTION
[0002] In the modern world, the need for secure and effective locking protections for various objects is paramount. Individuals often possess numerous personal belongings, ranging from handbags and backpacks to diaries and plastic pouches, plastic containers, packaging with openings and closures, and valuables. These products require reliable methods to ensure their security and protect the privacy of their owners.
[0003] Traditional locking systems, while functional, can be bulky, heavy, or lack versatility, creating a demand for innovative, lightweight, secure solutions that are adaptable to a variety of objects. Key locks require a physical key, which can be misplaced, lost, or stolen, while digital combination locks, although secure, can be vulnerable to unauthorized access through brute force or observation. Furthermore, existing locking systems may lack the versatility to easily integrate with a wide range of objects of varying shapes, sizes, and usage scenarios.
[0004] The history of this invention reflects the diversity of objects equipped with opening and closing mechanisms or valuable goods requiring secure storage. Whether at home, in the office, or in an institutional setting, there is a demand for a locking system that is easily customizable to adapt to different dimensions and security requirements.
[0005] The proposed system is distinguished by its modular approach and ease of use. It is based on a locking module available in several variants, adapted to different scenarios thanks to the integration of a variable drawer. This drawer determines the locking method specific to the object to be protected, thus allowing the use of a specific version of the module as needed. Although each The module is designed for a particular locking method, the analog slider mechanism, and the locking and unlocking method remain constant in all variants.
[0006] The emphasis on a control system based on a combination of sliders and a drawer-locking mechanism stems from the desire to improve the complexity and personalization of access control. Traditional key systems can be lost or duplicated, thus compromising security. This invention, thanks to its novelty and mechanical structure, allows the use of lightweight materials such as plastic, wood, and cardboard, in addition to conventional steel materials.
[0007] The invention is intended for application in various sectors, including residential, commercial, and institutional environments. Whether securing personal belongings at home or protecting valuables in retail stores or offices, it aims to provide a versatile solution that can be adapted to different use cases.
[0008] This locking system protects objects more simply than current products, as it does not require a key. Furthermore, its shape, functionality, and weight offer great ease of use on a daily basis. GENERAL DESCRIPTION OF THE INVENTION
[0009] The invention presented above is a sophisticated locking system designed to secure objects with opening and closing functions, as well as small valuables. The main element of the locking system is a locking module available in several variants depending on its variable drawer, allowing for several methods of locking the object. This module consists of a cover incorporating a combination module and a platform supporting a slide equipped with a variable drawer at the front, which can operate with or without walls depending on the locking method used.This system allows an object to be blocked from opening in several ways, or access to a small object within the locking module to be restricted, depending on the configuration of the variable drawer. The object can then be locked using a combination system selectable via sliding sliders on the lid. The variable drawer configuration is permanent, meaning that a locking module is used for only one locking method.
[0010] Access control for opening and closing the variable drawer, as well as locking and unlocking, is performed by the combination module and the slide regulator block, operating in tandem with sliding analog sliders. Opening or closing the variable drawer allows the object to be locked according to the locking method used. The locking module can lock an object using a strap attachment, a latch bar, a padlock shackle or a classic drawer.
[0011] When the locking method used is a strap fastener to protect the object's opening, the variable drawer consists of a drawer without sides and equipped with a slot. The locking module is attached, either alone or via a first strap, to one side of the object's opening. The second strap, having a drawer fastener at one end, is attached to the other side or to the same side of the locking module by its other end. This allows the drawer fastener to be secured in the open drawer without sides when the object to be protected is closed, and then locked inside the locking module when the drawer without sides is closed. Locking is then achieved using a lock combination selectable via sliding analog sliders on the lid.To unlock the item, the user must select the previously provided unlocking combination, then open the drawer without sides to remove the drawer fastener and unlock the item.
[0012] When the locking method used is a latch bar, the drawer without sides has a bar at the front. The locking module is fixed or sealed to one side of the opening of the object to be protected, while a strike plate, aligned with the latch bar of the locking module, is fixed to the other side of the opening. When the object is closed, opening the drawer without sides allows the object to be locked by inserting the bar into the strike plate, and then locking the entire assembly using a locking combination. To unlock the object, the unlocking combination provided to the user must be selected, and then the drawer without sides must be closed to release the bar from the strike plate.
[0013] When a padlock shackle is used as the locking method, the object to be protected is equipped with a grommet on each side of the opening, while the drawer without sides at the front is fitted with a shackle specifically designed for the locking module. This shackle connects the two grommets on the object when the drawer without sides is open, and locks the opening when the drawer without sides is closed. Locking is then performed using a combination lock. To unlock the object, the user must select the provided unlocking combination, then unlock the object by opening the drawer without sides using the drawer regulator and removing the shackle secured in the grommets.
[0014] When the locking method is ensured solely by the module, the variable drawer is a conventional drawer. The object to be protected is placed in the open conventional drawer, which is then closed inside the locking module. The module is locked using a combination lock. To access the object, the user must select the unlocking combination, then use the drawer regulator to open the conventional drawer and retrieve the object.
[0015] The flat, rectangular or square shape of the locking module allows for easy integration with various objects or standalone use. This locking system can be used to secure objects such as binders, plastic folders, cardboard boxes, as well as personal items like handbags, backpacks, jewelry boxes, diaries, and valuables. It can also be used in games or books where a variable drawer contains rewards, and the correct answer grants access to them.
[0016] The locking system can incorporate other locking methods without departing from its technical framework or its design. Furthermore, the locking module, the drawer fastener, and other locking elements can be adapted to take the shape of the object to be protected or an aesthetically pleasing form, provided that the operating mechanism remains unchanged despite this new shape.
[0017] This locking system can be made from lightweight materials, such as plastic, making it suitable for objects requiring only privacy protection, like a diary or a plastic folder. It can also be made from stronger materials, such as metal, to secure objects like suitcases, doors, cabinets, or cupboards.

[0078] With reference to [Fig. 1], an exploded view of the locking module 100 according to one or more embodiments of the invention is shown, incorporating various elements to ensure secure access control and object protection, with opening and closing functions or for an object alone. It is capable of locking objects with a variable drawer (121). And according to several embodiments, the variable drawer (121) can be without sides (121-A) or a conventional drawer (121-B). If the locking method is a fastening strap (200), the drawer without sides (121-A) includes a slot (124). If the locking method is a latch bar, the drawer without sides (121-A) is equipped with a latch bar (125) at the front. If the locking method uses a padlock shackle, the drawer without sides (121-A) includes a padlock shackle (126) at the front. And if the locking method is a conventional drawer (121-B), the variable drawer (121) is composed of sides (127).The following description first presents a preferred embodiment of the invention, then details the different variants.
[0079] The locking module (100) consists of a cover (101) at the top, incorporating a combination module (115) having labeled slotted guides (116), operating with analog sliders (111), and a tray (133) at the bottom. The tray supports a linearly moving slide (120), guided by lateral slide guides (134). The slide (120) comprises a variable drawer (121) at the front, a slide regulator block (128) in the center, and a variable drawer regulator (122) at the rear. The slide (120) is designed to slide forward and backward within the locking module, thus allowing the variable drawer (121) to be opened or closed by means of the drawer regulator (122).
[0080] The cover (101) and the tray (133) are essential components of the locking mechanism, providing protection, stability, and structural support. The cover (101) is rectangular and operates along its width. The cover (101) is sized to fit the tray (133), has a front opening (102) corresponding to the dimensions of the variable drawer (121), and a rear opening (103) adapted to the dimensions of the variable drawer regulator (122). A housing (104) is provided on the cover (101) for sealing or securing the combination module (115). The cover (101) includes side edges (105) at the front opening (102) and also side edges (106) at the rear opening (103) to conceal and protect the mechanism inside the locking module (100). In addition, the cover (101) serves as protection for the internal components of the locking module (100).The lid (101) can be made of various robust materials, such as metal, wood, plastic, reinforced cardboard or any other durable and resistant material.
[0081] The platform (133) is rectangular in shape and operates along its width. The platform (133) is composed of the lateral slide guides (134) which support the slide (120) on the platform (133), thus allowing it to guide the sliding forward and backward inside the locking module (100). Each lateral slide guide (134) operating on the width consists of a vertical strip (135) and a horizontal strip (136).
[0082] Each lateral slide guide (134) is positioned at the edges of the lateral sides of the tray (133), leaving a gap equal to the thickness of the lid (101) and a clearance. The length of each lateral slide guide (134) is dimensioned to match the lateral length of the slide regulator block (128), and the height of the vertical strip (135) is adjusted to be slightly greater than the thickness of the slide (120), with an additional clearance, thus ensuring smooth and frictionless operation. The tray (133) can be equipped with a first strap (139) positioned at the rear via a first fastening loop (138). The tray (133) can be made of various robust materials, such as metal, wood, plastic, reinforced cardboard, or any other durable and resistant material.
[0083] The analog cursor (111) consists of a cursor head (112) and a lower rod (113) with a mounting tab (114). The head (112) allows a symbol to be selected on the symbol panel (118) by moving it linearly in the cursor slot (117). The mounting tab (114) allows the cursor (111) to be attached to the cursor slot (117) via the insertion slot (119) of the labeled slot guide (116) of the combination module (115). This assembly allows the analog cursor (111) to slide freely along the entire length of the cursor slot (117) of the labeled slot guide (116). The end of the lower rod (113) is designed to engage with the corresponding slot guide (129) of the slide regulator block (128). The analog slider (111) can be made from various robust materials, such as metal, plastic, or any other durable and resistant material.
[0084] The combination module (115) is rectangular in shape and operates along its width. It has dimensions suitable for attachment to the housing (104) via the inner face of the cover (101). This module comprises at least two labeled slot guides (116) operating along their length, each equipped with a slider slot (117), a symbol panel (118), and an insertion slot (119) connected to the slider slot (117). The combination module (115) can be made of various robust materials, such as metal, wood, plastic, reinforced cardboard, or any other durable and resistant material.
[0085] Each labeled slotted guide (116) is connected, via an analog slider (111), to a slotted guide (129) located below it in the slide regulator block (128). The symbol panel (118) displays a set of symbols, including a symbol specifically associated with the unlocking combination.
[0086] Each labeled slot guide (116) operates along its length and uses an analog slider (111). The slider slots (117) of each labeled slot guide (116) are positioned on the combination module (115) so as to align with the front horizontal slots (130) of the corresponding slot guides (129) when the variable drawer (121) is in the closed position and to align with the corresponding rear horizontal slots (131) when the variable drawer (121) is in the open position.
[0087] The space allocated to each symbol on the symbol panel (118) is at least equal to the diameter or thickness of the lower stem (113). The total length of the symbol panel (118) is calculated by multiplying the diameter or thickness of the lower stem (113) by the number of symbols, plus the space allocated between the symbols.
[0088] The width of the slider slot (117) is equivalent to the diameter or thickness of the lower rod (113), with additional clearance to ensure smooth movement. The length of the slider slot (117) is equal to the length of the symbol panel (118).
[0089] Once the combination module (115) is permanently fixed in the cover (101), either by high-strength adhesive, screwing, welding, or any other suitable method, the labeled slotted guides (116) and the slider heads (112) become accessible to the user. However, the insertion slots (119) remain concealed and inaccessible from the cover (101).
[0090] The slide (120) is a pivoting element of the locking module (100), which incorporates several essential components. At the front, it is equipped with a variable drawer (121), and in the center, with a slide regulator block (128). The latter comprises a number of slotted guides (129) corresponding to the number of labeled slotted guides (116) present on the combination module (115). The slotted guide (129), which operates along its length, consists of a front horizontal slot (130) and a rear horizontal slot (131), both connected by a vertical slot (132). At the rear, the slide is provided with a variable drawer regulator (122) which is used to control the opening and closing of the variable drawer (121). This regulator also includes a finger grip (123) to facilitate handling.The variable drawer (121) and the slide regulator block (128) are rectangular in shape, operating along their width, and the drawer regulator (122) is rectangular in shape, operating along their length. The slide (120) can be made of various robust materials, such as metal, wood, plastic, reinforced cardboard, or any other durable and resistant material.
[0091] The distance between the front end and the rear end of the variable drawer (121) is equal to the width of the slotted guide (129), which is the distance between the front horizontal slot (130) and the rear horizontal slot (131). The distance between the lateral ends of the variable drawer (121) is less than the distance between the lateral ends of the slide regulator block (128), reduced by twice the thickness of the cover (101).
[0092] The slotted guides (129) are strategically placed in the slide regulator block (128). The first slotted guide (129) is positioned from the end of the variable drawer (121), leaving a space equal to the width of one slotted guide (129). The other slotted guides (129) are then arranged with a spacing equal to or less than the width of one slotted guide (129) between them.
[0093] Each slotted guide (129) is associated with a labeled slotted guide (116). Each labeled slotted guide (116) uses an analog slider (111), the end of whose lower rod (113) is engaged in the slotted guide (129) to slide in the slots (130, 131) and used by the vertical slot (132).
[0094] Each lateral space of the slide regulator block (128) is greater than the width of the horizontal band (136) of the lateral slide guide (134). The front horizontal slots (130), rear horizontal slots (131), and vertical slots (132) of the slotted guide (129) have a width equal to the diameter or thickness of the end of the lower rod (113) of the analog slider (111), with sufficient clearance to ensure proper operation. The length of the front horizontal slots (130) and rear horizontal slots (131) is the same as that of the slider slot (117), while the length of the vertical slot (132) is at least equal to the width of the front horizontal slot (130).
[0095] The distance between the front and rear ends of the slide regulator block (128) is determined by the number of slotted guides (129). The distance between the lateral edges of the slide regulator block (128) is defined as a function of the length of the slotted guide (129) and the width of its lateral spaces.
[0096] The vertical slot (132) of each slotted guide (129) is positioned to align with the symbol corresponding to the correct unlocking combination on the symbol panel (118). The height of the lower rod (113) of the analog slider (111) is set to allow the end of the lower rod (113) to engage in the slotted guide (129).
[0097] The distance between the front and rear ends of the drawer regulator (122) is equal to 1.2 times the width of a slotted guide (129). The distance between the side edges of the drawer regulator (122) is less than the distance between the side edges of the slide regulator block (128) and twice the thickness of the cover (101).
[0098] To select the unlock combination, the heads of the sliders (112) are moved manually through the labeled slotted guides (116) and then aligned with the correct symbols of the unlock combination. When the unlock combination is correctly selected by positioning each analog slider (111) on the appropriate symbol of each labeled slotted guide (116), The end of the lower rod (113) of each analog slider (111) aligns with the vertical slot (132) of the corresponding slotted guide (129). This alignment is essential to allow the unlocking of the variable drawer (121), which can then be opened or closed according to its initial position in the locking module (100).
[0099] To lock the variable drawer (121), it must be moved to the closed or open position using the variable drawer regulator (122), and then a locking combination must be selected. To unlock the variable drawer (121), whether it is in the closed or open position, the user must select the unlocking combination provided to them, and then move the variable drawer (121) to the open or closed position using the variable drawer regulator (122). The locking combination is different from the one used for unlocking. A locking combination involves selecting an incorrect symbol on at least one symbol panel (118) of a labeled slotted guide (116).
[0100] The slotted guides (129) in the locking module (100) participate in a variable drawer access control system (121), based on the selection of the combination via the analog sliders (111), thus reinforcing the security of the locking mechanism as a whole.
[0101] The slide (120) can be made of various robust and durable materials such as heavy-duty cardboard, metal, plastic, or any other material suitable for prolonged use.
[0102] When the variable drawer (121) is in the open position, the ends of the lower rods (113) of the analog sliders (111) are engaged in the corresponding rear horizontal slots (131). When the variable drawer (121) is in the closed position, these ends are engaged in the corresponding front horizontal slots (130). During the opening or closing of the variable drawer (121), the slide (120) moves, allowing the ends of the lower rods (113) of the analog sliders (111) to pass through the corresponding vertical slots (132) without the lower rods (113) themselves moving.
[0103] Thus, when the variable drawer (121) is opened from a closed position, the slide (120) positions the ends of the lower rods (113) in the rear horizontal slots (131) after passing through the vertical slots (132) from the front horizontal slots (130). When the variable drawer (121) is closed from an open position, the slide (120) returns the ends of the lower rods (113) from the rear horizontal slots (131) to the front horizontal slots (130) via the vertical slots (132), without moving the rods themselves.
[0104] The cover, equipped with screw connectors (107), is securely fixed to the tray (133) via its fixing holes (137), using screws (141).
[0105] The distance between the front and rear ends of the tray (133) is at least equal to the front and rear ends of the slide (120), the width of a slotted guide (129), and twice the thickness of the cover (101). The distance between the lateral edges of the tray (133) corresponds to the distance between the lateral edges of the slide regulator block (128), increased by twice the thickness of the cover (101) and twice the thickness of the vertical strip (135) of the lateral slide guide (134), plus a clearance on the sides to allow for the proper operation of the slide (120).
[0106] The platform (133) provides a stable base for the slide (120), with the slide's lateral guides (134) positioned along its sides. The edges of the lateral faces of the slide regulator block (120) are inserted into these lateral guides (134), allowing smooth forward and backward movement of the slide (120). The platform (133) can be made of steel, wood, plastic, or any other durable material.
[0107] Since the locking method used for this locking module (100) is a strap attachment (200, [Fig. 2]), the drawer without walls (121-A) is provided with a slot (124). The locking module (100) is sealed using a first strap (139) via a first attachment loop (138) on one side of the opening of the object to be protected.
[0108] In one embodiment, the locking module (100), the cover (101), the combination module (115), the tray (133) can operate in their lengths.
[0109] In one embodiment, the variable drawer (121), the slide regulator block (128) can be square or rectangular in shape operating along their length, and the drawer regulator (122) can be rectangular in shape operating along its width.
[0110] In one embodiment, the locking module (200) can be sealed on one side of the opening of the object to be protected by the external fixing points (140).
[0111] In one embodiment, the strap attachment (200, [Fig.2]) is sealed to the same side as the locking module (100), with a second strap (203, [Fig.2]) or sealed to the locking module (100) with the second strap (203, [Fig.2]) via the first attachment loop (138).
[0112] In one embodiment, when the locking method used is a latch bar, the drawer without sides (121-A) is equipped with a latch bar (125) at the front. The diameter or thickness of this bar (125) corresponds to that of the slide (120). The latch bar (125) has a length greater than the distance between the front and rear ends of the drawer without sides (121-A). The locking module (100) is fixed to one side of the opening of the object to be protected by external fixing points (140), while a strike plate compatible with the latch bar (125) is installed in the other side of the object's opening. Thus, when the object is closed, the open position of the drawer without walls (121-A) allows the bar (125) to be locked in the strike plate and the object to be secured by a locking combination.
[0113] To unlock the object, simply select the unlocking combination, then close the drawer without walls (121-A) in order to release the bar (125) from the latch and allow the object to be opened.
[0114] In one embodiment, when the locking method is a padlock shackle, the drawer without sides (121-A) is equipped with a padlock shackle (126) at the front. In this case, the locking module (100) is either fixed or sealed to one side of the opening of the object to be protected by the first strap (139), or used without fixing. The object to be protected has eyelets on both sides of its opening, so that, when closed, the drawer without sides (121-A) in the open position allows the eyelets to be pinned with the shackle (126), and closing the drawer without sides (121-A) allows the end of the padlock shackle (126) to be inserted into a shackle slot and to lock the object by holding these eyelets in place and to secure the object by a locking combination.
[0115] To unlock the object, the unlocking combination must be selected via the analog sliders (111), then the drawer without walls (121-A) must be opened to release the handle (126) and removed from the eyelets.
[0116] The padlock shackle (126) has a thickness equal to or less than that of the slide (120). Its lower height is designed to accommodate two eyelets, and the distance between the end of the shackle and the front of the drawer without sides (121-A) is less than the distance between the front and rear ends of the drawer without sides. The inside width of the padlock shackle (126) is greater than the distance between the lateral ends of the front opening (102) and less than the distance between the lateral ends of the slide regulator block (128), so that, when the drawer without sides (121-A) is closed, the end of the shackle (126) can be accommodated in the shackle slot on the front edge (110) of the cover (101).
[0117] In one embodiment, when the locking method is a conventional drawer (121-B), the variable drawer (121) is provided with walls (127). In this case, the object to be protected is placed inside the open conventional drawer (121-B), which is then closed in the locking module (100) and locked by a locking combination.
[0118] To unlock the object, it is necessary to select the unlocking combination using the analog sliders (111), then open the conventional drawer (121-B) using the variable drawer regulator (122) in order to access the object.
[0119] The variable drawer (121), such as the drawer without sides (121-A) equipped with a slot (124), a latch bar (125), a padlock shackle (126) or sides (127) of the drawer classic (121-B), is designed so that these elements are integrated into the manufacture of the slide and made with the same material.
[0120] Reference is now made to [Fig. 2], which is a perspective view of the strap fastener 200. The strap fastener (200) consists of a second strap (203), a drawer fastener (201) including a hook (202) underneath, the first end of the second strap (203) being attached to the second attachment loop (204). The hook (202) of the drawer fastener (201) is used to engage with the slot (124, [Fig. 1]) of the drawer without sides (121-A) to clip the drawer fastener (201) into the drawer without sides (121-A).
[0121] The second end of the second strap (203) is sealed either to the side where the locking module (100) is attached or sealed, or to the other side of the opening of the object to be protected, or to the first attachment loop (138, [Fig. 1]) located at the rear of the tray (133, [Fig. 1]). The width of the drawer attachment (201) is that of the drawer without sides (121-A), and the length of the drawer attachment (201) is greater than or equal to the length of the drawer without sides (121-A) and has a thickness greater than or equal to the thickness of the slide (120, [Fig. 1]). The thickness of the hook (202) is adapted to the slot (124, [Fig. 1]), and the height of the hook (202) is less than the thickness of the slide (120, [Fig. 1]). The width of the drawer attachment (201) corresponds to that of the drawer without sides (121-A). The length of the drawer attachment (201) is greater than or equal to the distance between the front and rear ends of the drawer without sides (121-A).
[0122] The strap attachment (200) is sealed on the other side of the object's opening with a second strap (203) via a second attachment loop (204). The width of the second strap (203) is less than the length of the second attachment loop (204). The length of the second strap (203) is determined according to the position of the locking module (100) on the object to be protected, thus allowing for optimal adjustment and secure fastening.
[0123] The hook (202) of the drawer fastener (201) engages in the slot (124), allowing the drawer fastener (201) to be securely attached to the drawer without sides (121-A). The drawer fastener (201) is then held inside the locking module by closing the drawer (121-A). To lock the drawer fastener (201) in the locking module (100), a locking combination must be selected. The drawer fastener (201) of the strap fastener (200) is made of various robust materials, such as steel, wood, plastic, reinforced cardboard, or any other durable and resistant material, and the first (139, [Fig. 1]) and second strap (203) are made of various robust materials, such as metal mesh, resistant fabric, or any other durable and resistant material.The slot (124) of the drawer without walls (121-A) could be placed at a distance less than the width of the slotted guide (129) from the rear end of the drawer without walls (121-A).
[0124] To unlock the object, the user must select the unlocking combination, open the drawer without sides (121-A), and detach the drawer fastener (201) from the drawer (121-A, [Fig. 1]). The locking combination is different from the unlocking combination.
[0125] Referring to [Fig. 3A], which illustrates a perspective view, it can be seen that the tray (100a) is equipped with a first attachment loop (138). The tray (133) has at the rear a first attachment loop (138) as well as a first strap (139). One end of the first strap (139) is sealed to the first attachment loop (138), while the other end is fixed or sealed to one side of the opening of the object.
[0126] The width of the first strap (139) is less than the length of the first fastening loop (138), and the length of the first strap (139) is adjusted according to the position of the locking module on the object to be protected, ensuring optimal and secure support.
[0127] In one embodiment, the first attachment loop (138) is used by the second strap (203).
[0128] Reference is now made to [Fig. 3B], which illustrates a perspective view of the plate 100b, showing the presence of external fixing points (140). In an alternative embodiment, the plate (133) may include external fixing points (140), which facilitate its attachment or sealing to the object to be protected, thus improving the stability and security of the assembly.
[0129] Referring to [Fig. 4A], which shows a view of the front face of the cover (100c) without the first front edge (108), the following characteristic is observed: the cover (101) does not have a first front edge (108, [Fig. 4B]) at the front opening (102) when the locking module (100) is used with a drawer without sides (121-A) equipped with a slot (124). This design has been carefully considered and is intentional, with the aim of ensuring optimal access to the variable drawer (121) without any obstruction. Furthermore, this configuration allows the locking mechanism to be supported inside the locking module (100), thus ensuring its proper operation.
[0130] In one embodiment, the variable drawer (121) is a classic drawer (121-B), the cover (101) does not have a first front edge (108, [Fig.4B]) at the front opening (102).
[0131] Referring now to [Fig. 4B], which shows a view of the front face of the cover (100d) with the first front edge (108). In one or more embodiments, the cover (101) has a first front edge (108) at the front opening (102). When the locking module (100) is used with a drawer without sides (121-A) equipped with a latch bar (125, [Fig. 1]) or a padlock shackle (126, [Fig. 1]), the cover (101) has a first front edge (108). This edge has a height equal to or greater than the thickness of the fixing tab (114) of the analog slider (111), while allowing the necessary clearance for optimal operation.
[0132] Referring now to [Fig. 5], which shows a view of the rear face of the cover 100e with the second front edge (109). The drawer without walls (121-A) equipped with a slot (124, [Fig. 1]), has a second front edge (109) at the rear opening (103) of the cover (101) whose height is equal to the thickness of the drawer attachment (201, [Fig. 2]), with a clearance.
[0133] In one or more embodiments of the locking module: when the locking module (100) uses a drawer without walls (121-A) equipped with a latch bar ([Fig.1], 125) or a padlock shackle ([Fig.1], 126), the cover (101) is equipped with a second front edge (109) at the rear opening (103) whose height is equal to or greater than the thickness of the fixing tab (114) of the analog slider (111), while allowing the necessary play.
[0134] When the locking module uses a conventional drawer ([Fig.1], 121-B) with walls (127), the cover (101) has a second front edge (109) at the rear opening (103) whose height is equal to that of the wall (127) of the conventional drawer (121-B), with a gap.
[0135] With reference to [Fig. 6], which illustrates, on the one hand, the strap attachment (200) and, on the other hand, the locking module (100), as well as their arrangement on an object to be protected, it should be noted that the locking method used by the locking module (100) relies on the strap attachment (200). The drawer without walls (121-A) is equipped with the slot (124). The module (100), equipped with a first strap, is sealed to one side of the opening of the object to be protected, while the strap attachment (200), equipped with a second strap (203), is sealed to the other side of the opening of the object.
