Description

ARCHETE SEALING DEVICE. USEFUL FOR THE ASSEMBLY OF THE DEVICE AND PROCEDURE FOR YOUR

MOUNTING

D E S C R I P C I Ó N

OBJECT OF THE INVENTION

The present invention, as expressed in the statement herein, refers to a device configured for the sealing of all types of boxes, so that once it has been arranged inside the casket it can only be opened by means of the use of the specific mounting wrench with which the installation is performed. Likewise, the necessary steps are described for mounting in a box.

More specifically, the device is formed by a blade-shaped anchor which is attached at multiple points to the wall of the case, and a cover that is screwed to said anchor and is arranged at a height that allows the subsequent arrangement of the cover of the casket, the device being hidden.

FIELD OF APPLICATION OF THE INVENTION

The present invention will have application within the field of security, more specifically within the protection of arches, so that it can be applied to all related industry, such as civil works, underground installations, land development, etc. It is therefore configured as a security element for the protection of the installation as a whole. Since its main application is to prevent theft produced by opening the enclosures of an installation, it will bring significant savings in the conservation and maintenance of all kinds of buried facilities, thus bringing significant benefits in maintenance work.

BACKGROUND OF THE INVENTION

The problem of robberies produced in underground installations of all kinds such as sewers, power lines, distribution of liquids or gases, etc. entails significant costs associated with the replacement of the stolen material. The elements object of the theft are very diverse such as the power lines cable itself, valves in plumbing or gas distribution facilities, electronic programmers in irrigation facilities, etc.

Theft of the casket's own cover implies, in addition to the cost involved in its replacement, a significant risk of accident until such replacement occurs.

There are also relatively frequent cases of theft of stored products, such as water from an irrigation storage, oil from a production company, diesel from a buried tank, etc. where such thefts have in common the fact that the subtraction has occurred through the opening of a casket.

For all this, it would be desirable to have a device installed in a casket, preventing it from being opened by unauthorized personnel, where at the same time the installation of said device did not imply an obstacle to the maintenance of the installation. Likewise, it would be desirable for said device to be applicable to both newly executed and easily installed boxes in already executed boxes.

It is known the existence of different designs of the casket lid that incorporate a lock or similar element that is actuated by means of a specific key that allows this cover to be anchored to the frame of the casket so as to prevent the opening, thereby blocking access to the inside. Devices for sale are also known as Fundilock, consisting of a metal disk that is screwed next to the edge of the lid by means of a safety screw, so that a part of the disk is superimposed on the lid and prevents opening if it has not previously been retired. However, although these elements hinder the removal of the lid manually, they do not effectively prevent theft when tools for breaking the locking element such as chisels, hammers, mallets, levers, etc. are used.

A practice that is being adopted to prevent theft through arches is the sealing of these with concrete, where a metal mesh containing zahorra inside is previously arranged on which a cake of a certain concrete thickness is arranged. In addition to the fact that this measure represents a significant impediment when carrying out maintenance or repair work on the installation, the impossibility of access to the casket by unauthorized personnel is also not guaranteed since such sealing can be removed with help of appropriate tools. Another similar practice is the application of welding points on metal covers of boxes, where this practice offers similar benefits to sealing with concrete. It is desirable by the cited in the two preceding paragraphs, the appearance of a device that offers sufficient mechanical resistance in order to prevent the opening of the casket in such circumstances, it being advantageous in addition to the fact that said device could also be anchored to the casing lid itself by securing it.

It is not known by the owner of the present report the existence of any device that offers the services described and that has a similar operating mechanism, so it is considered that the invention is configured as an obvious novelty. Based on this, the corresponding protection offered to this type of invention is requested.

DESCRIPTION OF THE INVENTION

The device for sealing arches object of the present application is configured from an anchor base piece which is screwed to the walls of the casket, on which sits a cover that joins the base piece by screw screwing of security or similar element, also providing a series of easels that rest on the ends of the base piece and serve as support for the lid.

The base piece is formed by a multiplicity of flat fins with preferably trapezoidal geometry, which are arranged vertically around a common axis that coincides with the geometric center of the casket. Each of these fins will have on its side closest to the wall of the casket where the device of one or more threaded elements is placed on which a stud is attached whose axis will be perpendicular to the wall of the casket so that when turning its advance or retreat is caused, approaching or moving away from said wall. Centered on the axis around which the fins are arranged there is another threaded element that is disposed welded to each of said fins and whose mission is to allow the coupling of a safety screw that will perform the function of union between the base piece and the cover of the device.

Each of the fins will also have a piece called an easel, configured as a support that sits on the stud itself and has a height such that the support of the lid on said easel is possible. To enable placement during assembly operations and ensure their immobility while the lid is arranged, the stands will have an arm that connects them to the fin by means of a joint.

The lid is configured as a flat element of geometry equal to that of the casket's own lid, but with dimensions slightly smaller than those of the frame where the casing lid sits. This cover will have in its geometric center a hole for the passage of the security screw that joins the cover itself to the base piece. The seating area of the head of the safety screw on the cover shall be disposed with respect to the rest of the cover so that the head of the screw does not protrude with respect to the upper plane of the cover, thereby forming a bowl in whose Bottom seat seats the screw. Optionally, the cover may have a reinforcement in its lower part that confers greater mechanical resistance to efforts of all kinds.

Optionally, it is also possible to use a cassette lid that is secured to the device lid, so that the cassette lid would have a hole in its geometric center with a seating area equal to that of the device lid, allowing so that the seat of the head of the safety screw will fix both elements to the base piece. For the installation of the device inside the case, it will be necessary to use a tool specifically designed for this function, consisting of a pair of profiles in the form of a blade with dimensions such that they rest on the frame of the case and whose crossing point will coincide with the geometric center of the casket. In said crossing point there will be a bowl with through hole in its interior and of dimensions coinciding with those of the seating area of the screw head in the cover of the device, so that the bottom of said bowl is at the same height as the lower plane of the device cover. A suitable screw arranged so that its head rests on the top of the bowl may be attached to the threaded element of the base piece, which will be suspended in the air hanging from this useful for installation which in turn will be supported by the frame of the casket.

The screw of the cover of the device, being a security screw, provides high security against opening, although additionally the device incorporates a specific cap that makes the task of opening to unauthorized personnel difficult. Said cap consists of a hollow cylinder whose base sits on the head of the screw and its outer diameter is equal to or slightly smaller than the inside diameter of the bowl so that the cap is fitted without significant clearances. The upper part of the cylinder is covered with a cover that will have a preferably conical geometry, so that its breakage is facilitated with a small cutter. The interior of the cylinder will be filled with marble or other material of similar characteristics, so that in the operation of removing the cap will consist of the breaking of the lid by means of milling cutter, aspiration of the marble of the interior and manual removal of the cylinder. The removal of the cap without the prior aspiration of the marble would cause it to fall to the sides of the head of the safety screw, thus preventing the insertion of a tool for rotating said head. The device installation procedure will consist of the following steps:

a) Attach a screw to the threaded element with vertical axis of the base piece, passing the screw through the bowl of the installation tool.

b) Location of the base and useful piece assembly on the casket, supporting the blade of the tool in the frame of the cassette.

c) Marked on the walls of the casket of the points where the studs will be inserted

d) Removal of the assembly and drilling of the marked points, making holes of adequate diameter to the studs of the base piece e) Removal of the screw that connected useful and base piece, placement in position of the base piece and screwed of the studs until inserted adequately in the holes made on the walls of the box

f) Layout of the easels

g) Screw the cover of the device with safety screw h) Insert the cap

i) Archery cover layout

DESCRIPTION OF THE PREFERRED EMBODIMENT In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below, not intended in Absolutely the present example limit the scope of this.

The device for sealing boxes (1) consists of a cover (2) that has a hole (14) in its geometric center which is located in a bowl (11) of depth equal to or greater than the height of the head of the safety screw (13) that will be arranged later to join the cover (2) with the rest of the elements.

The cover (2) also has a reinforcement (10) in its lower part, configured as a plate that forms a square and is welded to the lower plane of the cover (2).

The cover of the device (2) will be positioned so that its upper plane is below the lower plane of the casing cover (16). In this way, the cover of the device (2) will have dimensions smaller than the frame (15) to enable its insertion, leaving its upper plane located between the upper and lower planes of the frame (15). The clearance that will remain between the frame (15) and the device cover (2) must not exceed 5 mm.

The safety screw (13) sits on the bottom of the bowl (11) and is configured as the joint element of the lid (2) with an assembly formed by a multiplicity of flat fins (3), with trapezoidal shape, which are arranged in such a way that they are joined by their greater height, coinciding with the geometric center of the box (17), which in turn coincides with the axis of the safety screw (13). Although in the present example a device for sealing arches (1) with four is shown fins (3), different numbers of fins (3) can be used depending on the resistance needs of the device, so that the number of fins (3) used will not influence the essentiality of the invention.

The set of welded fins (3) is attached to the safety screw (13) by means of a nut (8) welded at the top of the greater height of each fin (3), which will have the appropriate dimensions for its perfect coupling to the screw (13).

At the smallest height of each fin (3) a nut and locknut assembly (4) with its axis arranged perpendicularly to the wall of the case (17) will be arranged. A stud (5) inserted in said nut and locknut assembly (4) may advance to be inserted into the hole in the corresponding wall of the cassette (18) made for this purpose.

For the arrangement of the nut and locknut assembly (4) and allow the stud to travel (5), a cutout (9) is made on each fin (9) thus enabling the stud shaft (5) to be centered with respect to the fin (3).

As indicated, the cover (2) of the device sits on a multiplicity of stands (6). These easels (6) are configured as rectangular plates that have a cut-out area at their bottom so that they properly seat on the studs (5).

So that the stands (6) remain correctly positioned during the assembly operation, they have arms (7) that are inserted into the respective holes of the fins (12) which act as an articulated point, so that to position the stand (6) will only have to insert the end of the arm (7) into the hole of the plate (12) and drop it on the stud (5) inserted in the hole in the wall of the box (18).

The plug (19) that is arranged on the safety screw (13) consists of a hollow cylinder (20) that is filled with marble (21) and on which a cover (22) of conical geometry is provided that facilitates its removal with the help of a strawberry or similar tool.

To assemble the device (1) on the box (17) it will be necessary to use a mounting tool (23) composed, in the case of square boxes, by two blades (26) at whose crossing point a support (24) where the safety screw (13) is to be inserted, said support (24) having a seating area (25) of the screw head (13) and the height at which said head seats both coincides with the use of the mounting tool (23) as with the device cover (2). The blades (26) will have dimensions such that their ends are coincident with the corners of the frame (15) of the case (17), so that the crossing point of said blades (26) will coincide once placed with the geometric center of the casket (17).

In this way, the assembly operation will consist of the following phases:

a) Coupling of the mounting tool (23) by means of the safety screw (13), threading it to the nut (8).

b) Location of the assembly on the box (17), supporting the blades (26) in the frame (15).

c) Marked on the walls of the box (17) of the points where the holes (18) will be made to subsequently insert the studs (5).

d) Removal of the assembly and drilling of the marked points, making holes (18). e) Removal of the screw (13), placement in position of the studs (5) and screwed until properly inserted in the holes (18) made on the walls of the cassette (17).

f) Layout of the easels (6).

g) Screw the device cover (2) with the safety screw (13).

h) Plug insertion (19)

i) Arrangement of the cover of the casket (16) Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to broaden its explanation so that any expert in the field understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be carried out in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection sought provided that it is not altered, change or modify its fundamental principle.
