Description

DESCRIPTION

Adaptable draft exclusion device for a door or window

Field of the invention

The present invention finds application, in general, in the field of thermal and acoustic insulation devices for doors and windows and, in particular, it relates to an adaptable draft exclusion device for use with accessories of different lengths.

Background of the technique

It has long been known that draft exclusion devices are mounted on the lower edge of fittings to close the gap between the fitting and the sill, limiting the passage of air and therefore any exchange of heat between the room and the outside environment.

These draft excluder devices can be provided in various designs, depending on how the gap is closed.

In general, the draft exclusion device has an elongated shape and is inserted into a seat that has been specially formed at the lower edge of the device.

Furthermore, the device comprises a profile received on the door seat and a sealing gasket that can be lowered automatically by actuating means as the door is closed.

For proper operation, the length of the device must match the width of the door in which it is installed.

Various arrangements are known for adapting draft exclusion devices to the actual width of the door or the accessory in which it is installed.

Document EP1033467 discloses a telescopic draft exclusion device, which is adapted to be lengthened or shortened according to the dimensions of the doors or accessories.

A first drawback of this arrangement is that the device can be lengthened or shortened within a predetermined range, and it can only be installed on doors that are within said range.

A further draft exclusion device is known, similar to that described above, the maximum length of which can be adjusted by cutting a portion of the end to a certain size.

A first drawback of this arrangement is that when the installer cuts the device down to a certain size, it can damage the drive mechanism and render the device unusable.

Furthermore, the gasket drive mechanism cannot be moved or eliminated to provide the installer with a wide margin of shortening.

Document GB2516977 discloses a draft exclusion device that can be adapted to the dimensions of the door on which it is installed by cutting an end part of it in which there is no actuating mechanism for the seal.

All the above-mentioned arrangements suffer from the drawback that the device manufacturer must keep devices of different lengths in stock, to supply them on request according to the different dimensions of commercially available doors.

Document JPH07317459 discloses a draft exclusion device that can be adapted to the dimensions of the door, having all the characteristics mentioned in the preamble of claim 1.

Technical problem

In light of the prior art, the technical problem addressed by the present invention is to provide a draft exclusion device of standard length, which can be easily adapted to doors or accessories of different sizes within a wide range without risk of damage their drive mechanisms.

Detailed Description of a Preferred Exemplary Embodiment

The figures show, in particular, an adaptable draft exclusion device, generally designated 1, which can be fixed inside a seat formed on the lower edge of an accessory, such as a door or a window, not shown.

The fixture may be hinged to a fixed frame with a jamb S, to rotate around hinges having a substantially vertical axis, which is also not shown.

The device 1 for excluding drafts can be automatically actuated by interaction with the jamb S, and comprises an outer profile 2, adapted to be fixed to the lower edge of the device, and a movable inner profile 3, which is slidably housed on the outer profile 2.

Advantageously, the inner profile 3 and the outer profile 2 have opposite cross sections, substantially U-shaped, with side walls 4, 4 'joined together by lower walls 5, 5', facing each other when the device 1 is in operating position.

The inner profile 3 can also include a sealing element 6 made of a yielding material whose function is to interact with the threshold of the door to hermetically block the passage of air.

The outer profile 2, the inner profile 3 and the sealing element 6 have substantially the same initial maximum length l, the value of which covers all possible door widths, or at least over a very wide range, for example, from 600 to 2,000 mm.

Conveniently, the initial maximum length l can be reduced by cutting an end portion of the profiles 2, 3 and the sealing element 6, using a suitable tool T, to adapt the device 1 to the actual width of the door or of the accessory on the one that is mounted.

Actuation means 7 of the inner profile 3 are provided, which are designed to automatically move the sealing element 6 between a raised position with respect to the threshold and a low position in contact with the threshold, and vice versa, after interaction with the jamb.

These actuating means 7 are known per se and comprise a button 7 'that protrudes from the edge of the device 1 to interact with the jamb S, and a movement conversion mechanism 7 ", to convert the movement from parallel to perpendicular to the threshold, so that the sealing element 6 will be displaced in the vertical direction.

Furthermore, the device 1 comprises two guide elements 8, 8 'interposed between the outer profile 2 and the inner profile 3, to keep the latter substantially parallel to the outer profile 2 as it moves in the vertical direction.

In a peculiar aspect of the invention, the device 1 comprises connection means 9, to fix one of the two guide elements 8 to the profiles 2, 3 in a final position close to the jamb S, and the other 8 'in a safe position, sufficiently far from the final portion to be cut, thus avoiding damage to it after cutting.

Each of the two guide elements 8, 8 'comprises a connecting rod 10 which is attached at its ends near two points of articulation of a pair of supports 11, 11'.

The supports 11, 11 'are defined by a pivot portion 12, which is adapted to be attached to the end of the connecting rod 10 and, an anchoring portion 13, for removable fixing to one of the profiles 2 and 3 between the respective side walls 4.

Conveniently, the coupling between the connecting rod 10 and the bracket 11 is obtained by means of an articulated pin 14, which can be snap-fitted into a corresponding cylindrical seat 15 formed in the pivot portion 12 of each bracket 11, 11 ' .

Furthermore, the anchoring portion 13 is fixed to each of the profiles 2, 3 by means of screw or plug connection elements 16, which fit into the corresponding through holes 17 of the supports 11, 11 '.

The supports 11, 11 'described above are adapted to be removably fixed to the outer 2 and inner 3 profiles in longitudinal positions selected by the user.

Therefore, a user can very easily act on the connecting elements 16 to adjust the anchoring position thereof in the profiles 2 and 3 using standard tools, such as a screwdriver.

In the first embodiment of the device 1, as shown in Figures 1 to 9, the connection elements 16 are of the screw type, for anchoring with the outer profile 2, and of the dowel type, for anchoring with the inner profile 3.

In this embodiment, the connection elements 16 are both perpendicular to the lower walls 5, 5 'of the profiles 2, 3 and interact with the latter by friction.

As shown in figure 8, to act on the connection elements 16, the outer profile 2 has a plurality of holes 18 arranged longitudinally at equal distances d 1 from each other, to receive a screw that is designed to lock the position of the support 11 adapted to be fixed to the outer profile 2.

Furthermore, the outer profile 2 may have additional alignment control holes 19 to control the alignment of the bracket 11 and the outer profile 2 and to facilitate quick screwing of the connecting element 16.

In this embodiment, the inner profile 3 has a plurality of supports 11 'which are stably fixed to the inner profile 3 in longitudinally equidistant positions, at a distance d 1 from each other.

These supports 11 'allow the connecting rod 10 to rotate in safe positions, far enough away from the end portion to be cut, according to the desired length of the device 1.

For this purpose, the user can translate one of the two guide elements 8 and fix it to a support 11 'at a distance from the portion of the cut end, thereby adapting the device 1 to the actual width of the door on which it is mounted, as shown in figure 9)

In the second embodiment of the device 1, as shown in Figures 10 to 16, the connection elements 16 are of the screw type, for anchoring the supports 11, 11 'to both the outer profile 2 and the inner profile 3.

In this embodiment, the connection elements 16 are both perpendicular to the lower walls 5, 5 'of the profiles 2, 3 and interact with the latter by friction.

As shown in Figures 12 and 15, to act on the connection elements 16, the outer profile 2 has a series of holes 18 arranged longitudinally at a distance d2 from each other, and formed in its upper wall 2 '.

The holes 18 have the purpose of allowing the passage of a screwdriver or similar tool to actuate a connection screw 16 to connect the support 11 'adapted to be fixed to the inner profile 3 and the passage of a connection screw 16 to hold the support 11 adapted to be fixed to the outer profile 2 in place, as shown in figure 15.

As shown in figure 16, in this embodiment, the user can easily translate the guide element 8 'by aligning the connecting elements 16 with the holes 18 formed in the outer profile 2 and in the safe position, far enough away from the extreme portion to be cut.

For this purpose, the user can translate one of the two guide elements 8 'and fix it at a distance from the end portion to be cut, thus adapting the device 1 to the actual width of the door on which it is mounted.

Therefore, in the first two embodiments of the draft exclusion device 1, before cutting the latter to adjust its length l, the guide element 8 'can be longitudinally displaced and locked through discrete passages according to the length of the end portion to be cut.

In the third and fourth embodiments of device 1, as shown in Figures 17 to 23 and Figures 24 to 29, respectively, the connection elements 16 are of the screw type for anchoring with the outer 2 and inner 3 profiles.

Advantageously, both supports 11, 11 'of the guide element 8' have elongated appendices 20 that extend in the same direction and whose ends are positioned aligned with each other and with the ends of the profiles 2 and 3.

In the third embodiment, the connection elements 16 are both perpendicular to the lower walls 5, 5 'of the profiles 2, 3 and interact with the latter by friction.

Furthermore, as best shown in Figures 20 and 21, the connection elements 16 for the connection of the supports 11, 11 'to the inner 3 and outer 2 profiles will be accessible to be actuated from the bottom and from the side. top, respectively.

In the fourth embodiment of the device 1, as shown in Figures 24 and 25, the connection elements 16 are of the screw type and both are substantially parallel to the lower walls 5, 5 'of the profiles 2, 3 to block one of the supports 11 by friction with respect to one of the side walls 4 of the outer profile 2, and the other support 11 ', with respect to the bottom wall 5' of the inner profile 3.

Therefore, in both embodiments, the user can easily position the guide element 8 'by aligning the ends of the elongated tabs 20 of the supports 11, 11' with the ends of the profiles 2, 3 whose length has been previously reduced, as shown in Figures 23 to 29.

As described below, a method is proposed for adapting and mounting a draft exclusion device 1 as described above for a device articulated to a frame and automatically actuated by interaction with a jamb S of the frame.

The method includes a step of a) providing an outer profile 2 adapted to be fixed to a lower edge of the device and a movable inner profile 3 slidably housed in the outer profile 2 and having a sealing element 6 designed to interact with a threshold.

The outer profile 2, the inner profile 3 and the sealing element 6 are selected, substantially, with the same initial maximum length l covering all possible door widths.

Next, a step of b) is provided that provides actuating means 7 of the movable inner profile 3, which are designed to automatically move the sealing element 6 between a raised position with respect to the threshold and a low position in contact with the threshold, and vice versa, by interaction with the jamb.

The method includes a step of c) interposing at least two guide elements 8, 8 'between the outer profile 2 and the inner profile 3, to keep the inner profile 3 substantially parallel to the outer profile 2 as it moves.

There is further provided a step of d) cutting an end portion of the profiles 2, 3 and the sealing element 6 to fit the actual width of the door on which the device 1 is mounted.

The method comprises a step of e) providing connection means 9 to fix one of the guide elements 8 to the profiles in a final position close to the jamb, and the other of the guide elements 8 'in a secure position, thereby far enough away from the final portion to be cut, to avoid it being damaged after cutting.

From the foregoing, it will be evident that the draft exclusion device and the method of adaptation and assembly thereof comply with the intended objects and, in particular, allow a reduction in its length while avoiding damage to the parts of the same.
