Description

DOOR LOCKING DEVICE

  The present invention relates to a door locking device of the type constituting a

  buffer associated with a means of fixing to a door.

  Several types of door locking device are already known in the prior art. They are intended as appropriate to prevent a door from closing on the fingers of a child or to avoid closings

untimely said doors.

  Among the known devices, there may be mentioned in particular the conventional door wedge device consisting of a blade of increasing thickness which is slid under the door and which prevents movement thereof by simple

wedge effect.

  The prior art also teaches the use of a U-shaped device, often made of rubber, which is slid between the door and its frame in order to prevent an unexpected closing of the door. The devices described above are removable and need to be sought in the place where they will have been stored when you want to use them. After use, these devices must of course be

new ranges.

  Other types of devices are still

described in the prior art.

  Among them, one can in particular quote a device which is formed of two elements, a stud fixed on the ground and a means fixed on the door. When the door is pushed towards the stud, the means fixed on the door comes to cooperate with the stud and achieve the junction of the stud and

  the door. The latter is thus blocked.

  However, this device has many drawbacks. In fact, the user can never approach the door of the stud without the door being blocked. In addition, the blocking of the door is only partial, insofar as it suffices for a person to pull or push the door for the device to disengage. Finally, the means attached to the door is unattractive since it often consists of a

  prominence coming beyond the plane of the door.

  A final device is described in European patent application No. EP 250 352. This patent application relates to a door block comprising a main cylinder placed on the ground, on which a flat blade is fixed by its first end. Said blade carries on its second end a second cylinder. The distance between the first and the second cylinder is chosen so as to be significantly greater than the width of the door. The thickness of the blade is chosen so as to allow it to pass under a door. When the user wants to block the door, he brings it close to the first cylinder. The blade of the device is in free rotation around the first cylinder placed on the ground which allows the user to bring the blade under the door. The second cylinder is thus separated from the first cylinder by

  the door and the latter is blocked.

  However, this device has the disadvantage

  to be extremely bulky and unsightly.

  The present invention aims to remedy at least in part the drawbacks presented by the devices

of the prior art.

  To this end, the present invention relates to a device for blocking a door comprising in particular a stopper associated by a link with a means for blocking the door, means allowing said link associated with the means for blocking the door to come and stay. inside of

  stopper as well as means for immobilizing said link.

  The device according to the present invention allows the link and the blocking means not to create discomfort when they are not in a situation of blocking the door since they are entirely, or possibly partially, housed in the body of the stopper. . Thus, the volume occupied by the device object of the present invention is substantially equivalent to the volume of a conventional stopper. In addition, the device of the invention according to the present invention does not have the disadvantage of constituting an aesthetic discomfort in the room of the house where it is used. The link associating the door blocking means with the stopper is advantageously made up of a

rigid material.

  In a first embodiment of the present invention, the link associating the means for blocking the door to the stopper is a rigid strip. According to this embodiment, the rigid strip is chosen so as to be of length greater than the width of the wafer (T)

  of the door and less than the width (L) of the stopper.

  In a preferred embodiment of the present invention, the door blocking means is constituted by a rigid element having a substantially "L" shape. This element can advantageously be constituted by the end of the rigid strip to which

  will have given the shape substantially in "L".

  The dimensions of the L-shaped element are chosen so that the door can be effectively retained when a user attempts to close it. On the face of the element L in contact with the door, there is advantageously arranged a piece of elastic polymer material, preferably rubber, so as to be able to avoid any wear of the door due to

friction or impact.

  According to this embodiment, the means allowing the rigid strip to be housed in the body of the stopper is a horizontal slot whose dimensions allow the passage of the rigid strip. Preferably, the rigid strip is placed at the

base of said stopper.

  In order to assist the door locking means described above, the device of the present invention also comprises means for immobilizing the rigid strip. These immobilization means are put into action by means for operating the immobilization means. The immobilization means are intended to assist the locking means of the device of the present invention. They are therefore used to avoid any movement of the tape when a person tries to

operate the blocked door.

  This embodiment of the present invention provides different means for operating the means for immobilizing the strip of the device according to the present invention. Among these means, there may be mentioned, by way of nonlimiting example, a system comprising a magnet. This system will also be described further in

  the embodiments of the present invention.

  The stopper is fixed to the ground by means of screws, advantageously the number of

  two, which may or may not pass through the body of the stopper.

  It is also intended to have one or more pieces of a rigid material, preferably metallic, and advantageously of cylindrical shape and of the same diameter as the stopper, under the stopper. These metal parts are provided with perforations provided for the passage of the screws. The primary purpose of these parts is to facilitate drilling or locating on the ground to secure the screws. A second advantage of these parts, in the case where the ground is not rigid (carpet, sand ...), consists in making it possible to prevent the carpet, or any other substance, from penetrating under the slot and thus hampering the

rigid strip movements.

  The stopper used according to this embodiment of the present invention has dimensions allowing it to receive the rigid strip serving as a link between the element of

door and stopper blocking.

  Other features and advantages of

  the invention will also appear in the description

  below embodiments given without limitation in which the appended figures represent: - Figure 1: Perspective view of a first

embodiment.

  - Figure 2: Top view of a second embodiment. In the embodiments represented in FIGS. 1 and 2, the door block (1) of the present invention is composed of a stop (2) associated by a link (3) with a blocking means (4) of the door, passage means (6) allowing said link (3) associated with the locking means (4) of the door to be housed inside the stopper (2) as well as immobilization means (7) of said

link (3).

  The stopper (2) is in the form of a commonly encountered door stopper. It is optionally covered with a layer of elastic polymer intended to protect it from impacts caused by the door near

which it is placed.

  The passage means (6) intended to allow a link (3) to be housed inside the stopper (2) preferably consist of a slot made at the base of the stopper (2). Thus, the means (6) will be judiciously chosen in order to present a configuration capable of allowing the passage of the link (3). Of course, the user of the door block of the invention will place the stopper so that the means (6) are oriented

  so that you can cooperate with the door.

  The link (3) associating the stopper (2) with a door locking means (4) is preferably made of a rigid material, possibly synthetic, and preferably metallic. When the link (3) is rigid, it takes the form of a

rigid band (31).

  The link (3) carries on one of its two ends a locking means (4) of the door. The locking means (4) and the stopper (2) are intended to be, firstly, placed on either side of the door. The locking means is then immobilized by the immobilization means (7) actuated by the user. Once the door is blocked, they prevent everything

door movement.

  Consequently, the dimensions of the link (3) are chosen so that its length is at least greater than the width of the edge (T) of the door and preferably less than the width (L) of the stopper (2). These dimensions allow on the one hand, when the device is in use, by locking means (4) of the door and the stopper (2) to be on either side of the door. On the other hand, and advantageously compared to the locking devices known in the prior art, when the device of the invention is not in use, the link (3) is able to be housed through the passage means (6), at

  less partially inside the stopper (2).

  This characteristic allows the device of the invention to present an attenuated aesthetic gene when the device is not used because the link (3) is not completely apparent. Thus, the user is not forced to store the device of the invention between

two uses.

  In order to ensure optimal locking of the door, the door block (1) of the invention comprises means

immobilization (7) of the link (3).

  The immobilization means (7) according to the invention consist firstly of a first means (70) placed in the body of the stopper (2), and secondly,

  a second means (75), placed on the link (3).

  The immobilization of the link (3) is obtained by cooperation

means (70) and (75).

  The stopper (2) is fixed by screws (8) and advantageously, one or more metal parts (10)

are arranged under the stopper (2).

  According to a first embodiment illustrated in FIG. 1, the immobilization means (7) placed in the body of the stopper (2) are of the type of a rod (71), possibly metallic, the height of which is at most equal at the height of the stopper (2). Said rod (71) can be moved vertically by any mechanism (72) known to those skilled in the art such as a lever mechanism or a magnet mechanism positioned on the cover. In its lower part, the rod (71) comprises a means capable of

  come to cooperate with the means (75), placed on the link (3).

  When the link (3) is constituted by the rigid band (31), the rod comes to cooperate with perforations (75) placed at

  regular intervals along the rigid strip (31).

  When the user wants to immobilize the rigid strip (31) of the locking device (1), he operates the rod

  so as to bring it into contact with the rigid strip (31).

  When the user wishes to implement the door block (1) of the invention, he removes the rigid strip (31) from its housing in the stopper (2), and then presses the door against the stopper (2). The stopper (2) must be oriented so that the door is placed against the face of the stopper (2) carrying the passage means (6). To block the door, the user simply has to replace the rigid strip (31) in the stopper (2) by passing it successively under the door then in the passage means (6) of the stopper (2). Finally, the user actuates the operating means (72) of the immobilization means (71) of the rigid strip (31) in order to achieve complete blocking of the door. This system has the advantage of allowing precise adjustment of the length of the strip.

  rigid (31) projecting from the stopper (2).

  According to a second embodiment illustrated in FIG. 2, the immobilization means (7) placed in the body of the stopper (2) are constituted by the assembly formed by an external wall (21), an internal wall (22) of the stopper (2) and a space (23) formed between them. When the link (3) consists of the rigid band (31), the immobilization means (75) positioned on the rigid band (31) consists of an "L" shaped element similar to the locking means ( 4) from the door. The internal wall (22) also has a discontinuity (24) intended to allow the sliding of the rigid strip (31) inside the stopper (2). The rigid strip (31) can therefore slide in the stopper (2) over its entire length between a maximum extended position and a maximum entered position; the sliding is limited by the contact of the locking means (4) against the external wall (21) for the entry and by the contact of the element (75) against the internal wall (22) for the exit. In addition, the element (75) in the shape of an "L" is chosen so as to be able to slide in the space (23) formed between the external wall (21) and the internal wall (22) when the rigid strip (31 ) is

maximum position extended.

  When the user wishes to implement the door block (1) according to this second embodiment, he must first completely remove the link (31) from its storage so that the door can be pressed against the stopper (2) without being hindered by the link (31), it places the door against the stopper (2), then replaces the rigid strip (31) in the maximum extended position by sliding the element (75) in space (23). The rigid strip (31) thus performs a movement in an arc of circle allowing the locking means (4) and the stopper (2) to be on either side of the door and to produce

thus its immobilization.
