Description

ELECTRIC PISTON AND GAS PISTON ADAPTED TO REINFORCED PISTON ASSEMBLY, TO LIFT THE TAILGATE OF ARMORED VEHICLES
[001 ] The present descriptive report refers to the application for invention patent of a pair of sleeves, both of them comprised by a tubular metallic body welded to a threaded coupler.
[002] Each sleeve will be inserted and fastened close to the opposite ends of the fixed and telescopic bodies of an electric piston, thus aligning their threaded couplers concentrically. Therefore, the sleeves, by their threaded couplers , will be used as support for a gas piston, which will be then fastened by screws in parallel to the electric piston, thus forming a reinforced piston.
[003 ] This configuration will enable that a single electric piston acquires greater telescopic force and strength to support the weight with the incorporation of the gas piston, to be installed on armored vehicles and lift easier the extremely heavy tailgate of its trunk.
STATE OF THE ART
[004] As already known, armoring is required in vehicles, but makes them heavier, not only in terms of total weight, but also on the hinged components , such as doors and tailgate.
[005 ] The own applicant of the application in question protected, also by patent application - BR 20 2014 007373 1, entitled as “DISPOSITION INTRODUCED IN ELECTRIC ACTUATOR FOR LIFT OF TAILGATE IN ARMORED VEHICLES ,” an electric actuator developed to withstand the load imposed by the weight of the tailgate, by an arrangement of helical compression springs mounted concentrically and involving the stem of the actuator spindle, in addition to the roller bearings on the ends of these springs, assisting the force to be imposed for lifting the tailgate and preserving the components for the telescopic motion. [006] As observed, the weight may make more difficult the operation of the lift piston in the trunk, which tailgate is driven by pneumatic system, thus not developed to withstand greater loads.
PATENT PURPOSE
[007] To solve the aforementioned problem, the inventor developed an adaptation, by using threaded couplers, on the electric piston for lift the tailgate of the armored vehicle, in order that it can be fastened by screws to a gas piston, equally adapted for this purpose, thus forming a reinforced piston.
[008] Once installed on the tailgate, in the trunk, and connected to the compres sion system of the armored vehicle, when actuated, the reinforced piston lifts the tailgate easily.
[009] When explained in a summarized way, the invention is better understood by the drawings attached herein:
[010] Figure l-perspective view of the pair of sleeves, with the first one shown on the top, formed by a tubular cylindrical body welded to a threaded coupler, and the second sleeve shown beneath the first, equally formed by a tubular cylindrical body, but of smaller size, welded to a threaded coupler;
[O i l ] Figure 2 - plan view of the pair of sleeves shown in the previous figure;
[012] Figure 3 - perspective view showing an electric piston;
[013 ] Figure 4 - view according to the previous figure, showing that the fixed and telescopic bodies of the electric piston are separated for introduction of the sleeves in a positioning studied;
[014] Figure 5 - view according to the previous figure, showing that, in the electric piston, the first sleeve was inserted to the end of the telescopic body and the second sleeve was inserted to the end of the fixed body ;
[015 ] Figure 6 - view according to the previous figure, showing that the telescopic body received the fixed body insertion, both of them provided with their respective sleeves, forming the electric piston. As observed, the first sleeve (on the telescopic body) has its threaded coupler perfectly aligned with the threaded coupler of the second sleeve (on the fixed body) ;
[016] Figure7 - view according to the previous figure, showing the electric piston already mounted, with the ends of the telescopic and fixed bodies, where the sleeves are installed, receiving each one a rubber cover for protection of their elements. Detail A shows the rubber covers separately and enlarged;
[017] Figure8 - sequence view of a gas piston, modified according to the proj ect, with a headless Allen screw, welded to the end of its telescopic body, to be screwed into the threaded coupler of the first sleeve, and an identical screw, welded to the end of its fixed body, to be screwed into the threaded coupler of the second sleeve;
[01 8] Figure 9 - view according to the previous figure, showing the gas piston already screwed and positioned in parallel to the electric piston, thus forming an electric piston reinforced by a gas piston;
[019] Figure l O - schematic view of the rear part of the armored vehicle with the tailgate closed. Shown on the top, separately and enlarged, is the reinforced piston not actuated yet, i.e. with the plungers in rest position;
[020] Figure 1 1 - view according to the previous figure, showing the tailgate being lifted by the compression system of the armored vehicle. As observed, after being actuated by the system, the electric piston charges the gas piston, in reinforced piston operation, to lift the tailgate easier.
[021 ] In compliance with the attached drawings, the “ELECTRIC PISTON AND GAS PISTON ADAPTED TO THE REINFORCED PISTON AS SEMBLY SYSTEM, TO LIFT THE TAILGATE OF ARMORED VEHICLES”, obj ect of this application for patent of invention, is comprised by a first sleeve ( 1 ) formed by metallic tubular body (2), with approximately 8cm of height, on which end, close to its lower edge, a threaded coupler is welded (3) . A second sleeve (4) is equally formed, by using a metallic tubular body (5), but with smaller height, approximately 3cm, on which is welded an identical threaded coupler (6)close to one of its edges , as shown especially in figures 1 and 2.
[022] Sleeves ( 1 ) and (4), thus composed, will be inserted in an electric piston (PE) of an automatic tailgate actuator for armored vehicle (VB ) , such as the electric piston (PE) shown in figure 3.
[023 ] As shown in figure 4, the electric piston (PE) has its body fixed (7) and separate from the telescopic body (8), which the first sleeve is inserted through ( l )by its tubular body (2), as indicated by dashed line, with the referred sleeve ( 1 ) sliding to a determined point of the cylindrical end (9)of the referred telescopic body (8), defined by the installer. Similarly, also indicated by dashed line, the second sleeve (4) will be inserted in the fixed body (7), fastened close to the free edge of its cylindrical end ( 10).
[024] The fixed (7) and telescopic (8) bodies will be then mounted again, as indicated by the dashed line in figure 5 , in the electric piston (PE) configuration, adjusted in order to positioning the threaded coupler (6) of the second sleeve (4) concentrically to the threaded coupler (3 ) of the first sleeve ( 1 ), as shown in figure 6.
[025 ] Thus, with sleeves ( l )and(4) inserted and duly positioned in the electric piston (PE), the cylindrical ends (9)and( 10) of the latter will receive, each one, their rubber coat or cover (C),by molding process, cold rubber coating, or any process for this purpose. Thus, both the cylindrical ends (9)and( 10) and the respective sleeves ( l )and(4)are protected and inserted in the electric piston (PE), by joining and fastening them, making their motion impossible, as shown in figure 7 and its detail A.
[026] Thus, the threaded couplers (3) and (6) of the respective sleeves ( 1 ) and (4), concentric, form a receiver support of a reinforcement gas piston (PG). As shown in figure 8, this gas piston (PG) , on the free end of its fixed body ( 1 1 ) is adapted with a headless Allen screw ( 12), and on the free opposite end of its telescopic body ( 13), adapted with another headles s Allen screw ( 14).
[027] By using the screw ( 12) of its fixed body ( 1 1 ) and the screw ( 14) of its telescopic body ( 13 ), the gas piston (PG) is screwed, respectively, to the threaded coupler (3) of the first sleeve ( 1 ) and the threaded coupler (6) of the second sleeve (4), drilling in these screwing points their corresponding rubber covers (B) . Thus, as shown in figure 9, the gas piston (PG) is mounted in parallel to the electric piston (PE), forming a reinforced piston (PR) to be installed, from the compres sion system of an armored vehicle (VB ), on the trunk, for lifting the tailgate (PO).
[028] Once installed on the trunk of the armored vehicle (VB ), the reinforced piston (PR) is connected to the compression system, as shown in figure 10, and by actuating the electric piston (PE), it will charge the gas piston (PG) to lifting and lowering the tailgate (PO)easier, even with the large weight acquired with the armoring.
[029] Thus, the reinforcement piston (PR) , combined with the gas piston (G), will assist to withstand the load, improving the performance, and consequently extending the electric piston durability (PE).
[030] The adaptations described in this report can be made in any type of piston that requires reinforcement, including pistons already adapted, as in the case of the obj ect claimed by the patent application BR 20 2014 007373 1, mentioned in the state of the art, deposited by the owner of the present patent application.
