Abstract

Centralized instantaneous sealed closing equipment which actuates immediately manually or mechanically all the lashings (18) by means of a rack (4) which is itself actuated by rotating a lever (1) and a gear or which is pushed linearly. The rack, through rods (7 and 11), displaces the vertical bolts (10) which, through rods (15 and 30), displace in turn the horizontal bolts (17) and the lashings (18) of which the wedged front face press against the frame (25) which is a section without orifice and without wedges. The tightening force of each lashing can be regulated so as to obtain a high tightness. The panel (24) incorporates the actuation mechanism and is armoured with a perimetral frame (21) containing the bushing to guide the lashings, is reinforced by means of the sections (27) and can be die-pressed for its regidification. A seal (23) is arranged between the edge of the panel and the frame, the lid (28) closing the assembly.

Description

E CENTRALIZED INSTANT CLOSURE SEALED TYPE.

OBJECT OF THE INVENTION

The object of the present invention is referred to as its title indicates, to a device (door or hatch) sealed of instant centralized closure, so that thanks to any manual or mechanical movement that starts from a lever and a pinion with a preferred rotation of 1472, or of directly and linearly pushing a zipper, transmit the movement of the zipper to the vertical fallebas, which by means of connecting rods transmit it in turn to the horizontal fallebas and to the lashes, so that the lashes are operated in a minimum time and allow to obtain a tight seal, as will be described later.

BACKGROUND OF THE INVENTION

The tight centralized quick-closing hinge devices that are currently used are currently opening and closing, either with a central steering wheel that transmits the movement to the lashes by means of pits housed in the equipment leaf, or with a lever located in the frame which transmits the movement to the various lashes by perimeter cranks also located in the frame.

Flywheel equipment usually has the following disadvantages:

Steering wheel movement, while still relatively fast, requires the order of 5 to 10 seconds, prohibitive time in some applications (military ships, for example), In addition, the transmission of the movement sometimes requires the use of complicated and expensive conical pinions, as well as fallebas and lashes, of adjustment, laborious and almost handmade.

- The lashing is usually done with guides housed in the frame, without individual adjustment of the tightening of each lash, expensive system, difficult alignment and no adjustment capacity, all of which entails a low tightness.

The mechanical resistance of the equipment is achieved based on high plate thicknesses and heavyweight profiles reinforcements. The placement of insulation requires a greater depth of the body of the equipment.

In addition, perimeter cranksets usually have the following disadvantages:

- Over time, the imbalances produced in each connecting rod are accumulated so that, in those furthest from the lever, the clearance is large and the transmission of the movement becomes defective, as a consequence, the tightening of the lashes is low and poorly synchronized between them causing problems of tightness, frequent maintenance for readjustment, delicate and laborious assembly, etc ...

- The bulkhead welding is usually butt which entails major problems of alignment of the equipment in the plane of the bulkhead, a problem to which the mismatches in the transmission of movement to the lashes produced by the stresses produced by the welding are added. DESCRIPTION OF THE INVENTION

In order to solve these problems, the centralized instantaneous sealing device of the present invention has been devised, the main body of which is formed by a leaf where the entire drive is arranged, this equipment being armed with a perimeter frame preferably of rectangular tube containing the bushings guide of the lashes, said sheet being

10 reinforced by a grid framework, preferably embedded with a pattern of rectangles generally to provide more mechanical resistance even with low sheet thicknesses. The assembly is closed with a metal cover, the structure _{t t} - resulting more resistant and lighter.

This waterproof equipment allows simultaneous operation of all lashes with a minimum maneuver time, thanks to any manual or mechanical movement

20 that starts from a lever and a pinion with a preferred rotation of 1 75, or from directly and linearly pushing a rack, thus transmitting the movement of the rack to the vertical fallebas which, by means of connecting rods, transmit it in turn to the fallebas

25 horizontal and to the lashes; these have the wedge-shaped front to press against the frame, so that frame does not need accommodation for them or additional wedges, each trench can be individually adjustable in high pressure models. Has

30 also a profile frame preferably in "Z", being able to have any other design suitable to withstand misalignment and tensions that occur when welded to the bulkhead. The sheet is armed with a perimeter frame containing the ferrules guide lashings is _"c reinforced by a network of reinforcements, also having a sealing gasket housed between the edge of the sheet and the frame, the assembly being closed with a sheet metal cover.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in Figure 1, the body of the equipment attached to the frame (25) by means of two or more hinges (31) is formed by the sheet of sheet (24), of low thickness, being able to be reinforced in some cases by means of inlay , with a pattern preferably in the form of rectangles and can be differently, and through the framework of profiles (27). The blade (24) is welded to the frame (21), whose missions are: reinforce the body of the team; housing the bushes (20) that guide the lashes (18), form the channel where the sealing gasket (23) is formed by its outer perimeter (24); and finally serve as a stop to the sheet metal cover (28). The frame (21) is, in general, a rectangular tube of low thickness with rounded or angled corners. The blade (24) also contains the entire mechanism of action of the equipment to transmit the movement of rotation of the lever to the line of action of the lashes: the lever (1), the pinion system (3) and rack (4) , vertical fallebas (10), connecting rods (15) and (30), horizontal fallebas (17) and lashes (18).

Figure 2 shows a detail of the transmission of the movement to the fallebas that allows to understand the way in which the turning movement of the lever (1) becomes a linear movement of the lashes (18). Said figure 2 represents the equipment completely closed with the lever (1) turned approximately 1472 downwards (represented by dashed lines in the drawing, being behind the sheet (24) containing the mechanism of the figure). With the equipment open, the lever (1) would be 2 beyond the vertical and the rack (4) would have its left end very close to the edge of the frame (21).

Starting from such an open equipment situation when the closing movement begins, the rotation of the lever (1) is transmitted by means of its axis (2) to the toothed pinion (3) which is welded to the axis (2). The pinion, in its turn to the right, also moves to the right to the rack (4) that has its left part serrated. The Pulley (5) serves as a guide to the movement of the rack 4 that remains centered thanks to the pulleys (6). When moving to the right, the rack (4) moves the connecting rods (7) articulated at its junction to the rack using the bolt (8) and the fork (9) of the vertical phalluses (10) (using the bolt (12) )). Initially (equipment without trincar) the connecting rods (7) form a certain angle with the horizontal with the concavity to the right. The angle opens more and more as you turn the

10 lever, the cranks get to form 902 _CO n horizontally and then slightly exceed this value (moment that represents the figure) with the concavity to the left (carved equipment). This reverse angle ensures the backstop of the mechanism to avoid opening

15 accidental equipment. During the closing movement, the axis of the bolt (12) moves away from the horizontal axis of the equipment, the axis (29) moving in a center circle and the length of the connecting rod (11) radius, as this connecting rod is articulated in its ends (shaft (29) and fork 0 (9)). Given the small amplitude of this movement, the arc described by the bolt (12) is practically equal to its rope, so it can be considered that the vertical failure (10) (integral with the fork (9)) is pushed vertically only in the direction of moving away from the horizontal axis 25 of the equipment.

In this vertical movement the vertical fallebas (10) move the rotating cranks (15) thanks to the lugs (13) (solidarity with the fallebas

Vertical _3Q (10)). These lugs (13) vertically push the bolts (14) attached to the rotating rod (15) but which can rotate freely to minimize friction. When the bolts (14) are pushed vertically, the rotating rods (15) rotate

, -, -. around the bolt (19) which moves describing a arc whose center is the bolt (16) (welded to the reinforcements (27)) and whose radius is that of the connecting rod (30).

The bolt (19) describes an arc of small amplitude whose trajectory is practically comparable to its rope. This bolt (19) is attached to the horizontal wall (17). As a consequence, the horizontal failure (17) moves almost linearly in a horizontal axis in direction to the outer edge of the equipment.

The lash (18) is connected to the horizontal failure (17) (or the vertical failure (10)) by means of a regulating device (22) consisting of a threaded rod and a locknut. By rotating the lash (18) the necessary turns, the distance from its front wedge to the frame (25) can be adjusted. Once all the lashes (18) are adjusted, their position is fixed using the lock nut of the regulating device (22). The lashes are guided in their movement by means of the bushings (20) welded to the frame (21). The lashes (18) in their outward motion push the blade (24) towards the frame (25), tightly tightening the seal (23). (See figure 3)

To ensure the structural rigidity of the assembly, occasionally the reinforcement network (27) is arranged forming a grid of profiles. The supports of the pulleys and the body of the axis of the lever are secured to this framework (27) by means of 1 iares auxi posters (26).

Figure 3 shows in detail the lashing of the blade against the frame. Also in this case it is a typical arrangement that varies slightly depending on the model of equipment considered. The front of the lash (18) is initially removed inwards (open equipment) so that it does not collide with the frame; when turning the lever to close the equipment, the lash (18) advances until it touches the back of the frame (25) with its wedge, from there the force exerted on the lever is transmitted greatly increased to the lashes (18) that they push the body of the equipment against the frame (25) causing the lip of said frame (25) to sink deeper and deeper into the seal (23), located between the edge of the sheet

(24) and the outer side of the perimeter frame (21) until the equipment is completely closed.

Also in Figure 3 you can also see the bushing (20) to guide the lashes, the regulating device (22) and the welded to it (vertical failure (10) or horizontal failure (17)). Thus, a possible arrangement of the sheet metal cover (28) can also be observed.

The adjustment device (22) allows the individual adjustment of each lash (18) by approximating it more or less to the frame (25) to regulate the clamping force and combine the simultaneous and balanced action of all the lashes (18) of the equipment, to In order to obtain maximum sealing with minimal effort.

Returning to Figure 2 and bearing in mind the concept of operation shown in Figure 3, the anti-reverse of the lashes (18) and lever (1) beforehand is understood: once the vertical has been passed in the movement of the connecting rods (7 ) (until they form an open reverse angle to the left) the frame thrust

(25) against the lashes (18) (once the lever (1) is released) causes the vertical fallebas (10) to get closer by increasing the inverse angle so that it never tends naturally to return to the position initial To avoid a large loosening of the pressure of the lashes (18) against the frame (25), a stop (32) is arranged on the horizontal axis of the equipment (on the rack line (4)) that limits the reverse angle formed by the connecting rods (7).

To open the equipment again it is therefore necessary to exert a slight force that overcomes the inverse angle formed until the movement of the mechanism is unlocked.

It is contemplated that there is an insulation which would be placed in the recess left by the reinforcement framework (27) since both the reinforcements and the insulation are in a plane parallel to that of the mechanisms described above without interfering with them.

On the equipment of which we have described a preferred embodiment, the possibility of presenting multiple variants according to the width and height of the equipment, the thickness and the type of material of the sheet (24) and the cover (28) and the shape is mentioned and dimensions of the frame profile (25) and the frame (21); the corner radius of the equipment, the location of the hinges on one or the other hand of the equipment, the number and distribution of the lashes (depending on the size of the equipment and the degree of tightness required); the existence or not of a gate or a window on the equipment; the existence or not of thermal, acoustic or fire insulation as well as its type and thickness, the execution with two sheets; execution with mobile threshold or with flush threshold; ballistic execution; the existence or not of a system of compensation of the weight of the equipment, by spring, counterweight or any other method; the existence or not of a second integrated equipment mounted on the principal; the existence or not of security locks as well as their nature and anchor points; the existence of a lever on both sides of the equipment or only one, the execution as safety equipment, with a second leaf after the main one; the existence of a hydraulic closure of open equipment and / or electromagnetic retention of equipment in the open position; the existence or not of the limit switches to monitor the status of the equipment; the existence or not of locks; the existence or not of an opening / closing mechanism and lashing / dethinning by power (hydraulic, pneumatic, electric or similar), etc.

It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom. The terms in which this report has been written must always be taken in a broad and non-limiting sense.
