Anti-theft rear mechanism with a magnetic opening system and a system of self-adjusting straps, for objects intended to hold elements, such as briefcases, backpacks or suitcases

Abstract

The invention relates to a rear protection mechanism with a magnetic opening system, intended for objects used to hold elements, such as, for example, briefcases, backpacks or suitcases, said mechanism acting as an anti-theft system for rear, side and/or lower pockets on said objects. The rear mechanism with a magnetic opening system (positioned against the user's body) consists of flaps with non-visible magnets located inside said flaps, which, upon coming into contact with other magnets located on the rear surface of the object, generate an attraction that secures the flaps, such as to prevent third parties from gaining access to pockets on the outside of the briefcase, backpack or suitcase. The invention also relates to a system of self-adjusting straps that allow the weight or load contained in the element-holding object.

DETAILED DESCRIPTION OF THE INVENTION

(16) Rear Anti-Theft Protection Mechanism with Magnetic Opening

(17) The rear magnetic-opening mechanism comprises three main elements (a) two side flaps (1), and a lower one (2), (b) a backrest (3) and (c) two safety bars (4).

(18) Each side flap (1) (FIGS. 5, 6 and 7) comprises a layer of fabric (5), a salpa film (6), a polymer panel (7) with two holes (8), two magnets (9), a tin plate (10), a polymer panel (11) and a foam panel (12). Thus, there are two magnets (9) in the center of each flap (1), which are located between a polymer panel (7) attached to a salpa film (6) and a tin plate (10). The polymer panel (7) has two holes (8) to place the magnets (9) in it. The two holes (8) are located vertically and parallel to each other. Once the magnets (9) are placed into the holes (8), the polymer panel (7) and the tin plate (10) are joined together by clamping them so that the magnets (9) do not move. Adjacent to the tin plate (10), there is another polymer panel (11) and a foam panel (12). At the end, all the above elements are covered by a layer of outer fabric (5) and forming a side flap (1).

(19) This description applies equally to both side flaps (1) (right and left).

(20) On the other side, in front of the lower flap (2) (FIG. 8), there is a layer of fabric (13), a salpa film (14), a polymer panel (15) with a hole (16), a magnet (17), a tin plate (18), a polymer panel (19) and a foam panel (20). Thus, there is a magnet (17) in the center of the lower flap (2). It is located between a polymer panel (15) attached to a salpa film (14) and a tin plate (18). The polymer panel (19) has a hole (16) to place the magnet (17) in it. This hole (16) is located in the center and at the bottom of the bottom flap (2). Once the magnet (17) is place in this hole (16), the polymer panel (15) and the tin plate (18) are joined by clamping so that the magnet (17) does not move. Adjacent to the tin plate (18), there is another polymer panel (19) and a foam panel (20). At the end, all the above elements are covered by a layer of outer fabric (13), forming a bottom flap (2).

(21) The side flaps (1) and the bottom flap (2) are attached by seams to the body of the backpack, in the side and bottom areas.

(22) In other instances, the rear anti-theft protection mechanism may be composed of a single, two or four flaps.

(23) In other instances, the flaps of the rear anti-theft protection mechanism may be located on top of the object designed to store elements.

(24) In another instance, the flaps of the rear anti-theft protection mechanism have internal pockets to store elements.

(25) In other instances, each flap of the rear anti-theft protection mechanism may have more or fewer than two (2) magnets.

(26) The back side (21) (FIGS. 9, 10 and 11) contains a layer of fabric (22), an EVA rubber panel (23) attached to a polymer panel (24) with five holes (25), five magnets (26), a tin plate (27), an EVA rubber panel (28) and two polymer safety bars (4). Thus, inside the backside (21), there are five magnets (26) distributed as follows: two magnets located on the upper left side edge of the backside (21) of the backpack, and parallel to each other. The other two magnets are located on the upper right-side edge of the backside (21) of the backpack, and they are parallel to each other. The last magnet is located in the lower central part of the backside (21) of the backpack. The safety bars (4) are located on the edges of each end of the backside (21) of the backpack and in parallel position, so that the magnets (26) are in the middle of both bars (4).

(27) Inside the backside (21), there are the five magnets (26) in the locations explained above. These magnets (26) are incorporated into a polymer panel (24), which is attached to another EVA rubber panel (23). The magnets (26) are incorporated into the polymer panel (24) through holes (25) made in it. Once the magnets (26) are placed into the holes (25), the polymer panel (24) is attached to a tin plate (27), clamping the magnets (26) so that they do not move. Adjacent to the tin plate (27), there is another EVA rubber panel (28). At the end, all the above elements are covered by a layer of outer fabric (22).

(28) In another instance, the backside of the rear anti-theft protection mechanism may be equipped with more or fewer than five (5) magnets.

(29) Taking into account the abovementioned elements, it occurs that the anti-theft protection mechanism works when the user joins, by means of the attraction of the magnets, the two side flaps (1) and the lower flap (2) to the backside (21) of the backpack. The safety bars (4) help the flaps (1-2) not slide sideways and be fixed to the backside (21). Thus, all the access pockets of the backpack are covered by the three flaps (1-2), which means that no third party may access them from the outside of the backpack.

(30) Self-Adjusting Strap System.

(31) The self-adjusting strap system (FIGS. 12, 13, and 14) includes two oval aluminum, brass, or steel grommets (29), a nylon or polyester fabric strap (30), two double aluminum, brass, or steel pins (31), two fabric connectors (32), a polymer panel (33) with two oval holes (34) on each end, a polymer panel (35), and two polymer bars (36).

(32) In one instance the double pins (31) are made of aluminum. In another instance, they are made of steel and in another instance, they are made of brass. Double pins are preferably made of aluminum.

(33) In one instance, the strap (30) is made of nylon material. In another instance, it is made of polyester. The strap is preferably made of nylon material.

(34) At the bottom of one of the shoulder pads (37) of the backpack, there is a fabric connector (32) that holds a double pin (31). The strap (30) goes through the pin (31), and it is inserted into one of the grommets (29), and passes through a hole (34) in the polymer panel (33), surrounding it at the back and coming out through the hole (34) at the other end of the panel (33) and inserting again into the other grommet (29) and crossing through the double pin (31) of the other shoulder strap (37). Between the polymer panel with oval holes (33) and the other polymer panel (35), there are two horizontal polymer bars (36), parallel to each other, which create a space between the two panels, so that they may allow the strap (30) to circulate easily and without friction.

(35) In fact, having a single continuous strap (30) joining the two shoulder pads (37) of the backpack, through a system that acts as a pulley, achieves continuous tension between the straps, which creates an automatic balance of the load in the backpack.

(36) In one instance, the object intended to store items such as a briefcase, backpack or suitcase only has the rear anti-theft protection mechanism with magnetic opening.

(37) In another instance, the object designed to store elements such as a briefcase, backpack or suitcase only has the self-adjusting straps system.
