Abstract

Closing for underground container lids, consisting of a key operated stud (4) (3); a tongue (5) mounted without rotation on said stud (4); a support (9) fixed to the frame (2) of the cover on which the stud assembly is arranged (4) / tongue (5) and a strike (6), fixed to the wall of the box, in which the tongue (5) is locked / released when it reaches two positions closing / opening ends by turning the key (3), with means for prevent the removal of the key (3) when the lock is not in closed position

Description

Closure for container lids buried.

The object of the invention is a closure for caps of underground containers.

In the current state of the art already known closures, simple structure and for various applications, based on turning a tongue by means of a key to reach, at least two open / close positions when released or not from a fixed strike.

Closures of this type are described by Example in Utility Models:

-

U9901 237 (figure 7) referred to mailboxes;

-

U200102256 (Figures 1 and 2) referred to electric control cabinets.

-

U0280469 (figure 1) referred to cabinets conventional.

An unsolved problem of this type of closure it's security and, in particular, the security of always leaving it closed when the user is not present.

This security is essential particularly in underground containers in which the lid of the cabinet must always be closed, when the operator is not Present.

The object of the invention solves this problem, advocating a closure for underground container lids with means to prevent removal of the key when the closure does not It is in closed position.

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1 represents an overview schematic of the closure object of the invention, assembled and arranged of use

Figure 2 represents a partial view in lid plant (1) with its torn window (7) and its cavity Revolution Central (72).

An example of practical, non-limiting embodiment of the present invention.

         \ vskip1.000000 \ baselineskip
      

In accordance with the invention, and according to the represented embodiment, the closure for container lids buried consists of the following component elements basic:

3.-

Key

4.-

Turning stud

5.-

Tongue

6.-

Keeper

9.-

Support

and means to prevent the removal of the key (3) when the closure is not in the closed position.

         \ vskip1.000000 \ baselineskip
      

For these purposes, the key (3) is a key of polygonal section and means to engage / disengage from turning bolt (4), in at least its coupling environment to said stud (4), which saves the lid (1).

The tongue (5) is mounted without turning on the stud (4). Both always turn jointly and severally to be operated by the key (3).

The strike (6) is mounted on the frame (2) of the casket in position such that it can be locked or released from it tongue (5) in its turn to reach, respectively, its closing and opening positions.

The particular configuration of the strike (6) It can be anyone who meets these ends. An example of embodiment has been represented in the figures illustrating this description.

         \ vskip1.000000 \ baselineskip
      

For the embodiment represented, the means that prevent the removal of the key (3) when the lock is not in closed position are:

-

in the key (3) a conformation (32), as a throat.

-

in the cover (1) a torn window (7), of geometry conjugated with the key section (3) and provided with a central cavity (72) of revolution, in which the throat of the key is housed (3) and can turn on it with respect to the cover (1).

         \ vskip1.000000 \ baselineskip
      

With this structure, layout and assembly:

to)

may lock the key (3) in the stud (4) in a position such that the key (3) goes through the window (7) of the cover (1);

b)

for open or close, it can be turned freely, in one way or another the key (3) embedded in the stud (4) and positioned in the lid (one);

C)

may remove the key (3) from the cover (1) only in a position in the one that the geometry of the key (3) and of the window (7) coincide; position that always corresponds to the closing position closed.

Claims (3)

1. Closing for underground container lids, characterized in that it consists of:

to)

a key operated stud (4) (3)

b)

a tongue (5) mounted without turning on said stud (4)

C)

a support (9) fixed to the frame (2) of the cover on which the stud assembly (4) / tongue (5)

d)

a strike (6), fixed to the wall of the box, in which locks / releases the tongue (5) when reaching two extreme positions of closing / opening by turning the key (3)

and)

means to prevent the extraction of the key (3) when the lock is not in the closed position; being said means:

e1)

in the key (3) a conformation (32), as a throat; Y

e2)

in the cover (1) a torn window (7), of conjugated section of the section of the polygonal key (3) and provided with a central cavity (72), constituted in revolution housing, in diameter conjugated with that of the aforementioned throat (32);

so that the key extraction (3) It is only possible when the closure is in the closed position. 2. Closing for underground container covers, according to the preceding claim, characterized in that the key (3) is a key with a polygonal section in at least its coupling environment to the stud (4) that saves the lid (1). 3. Closing for underground container covers, according to previous claims, characterized in that, the key (3) is a key with a conjugated rectangular section of the section of the torn window (7) in at least its coupling environment to the stud ( 4) that saves the lid (1).
