Abstract

The present finding relates to a draught excluding device for doors, comprising a channel-shaped support section bar (12) to be fixed to the base of a door ledge, a mobile member (13) mounted in the channel-shaped section bar and capable of moving upwards and downwards to and fro the floor, at least one seal carried by the mobile member, and means for connecting said mobile member to the support section bar. The mobile member is provided with a pusher (15) and with an abutment member (16) intended to rest against a stop (17) provided into the support section bar, so as to force the mobile member to lower when the pusher (15) engages with the door jamb, characterised in that two stop members (18) are fixed or obtained into a top portion of the support section bar (12) against which the stop (17) alternately abuts according to the door opening side.

Description

The present finding relates to draught excluding devices, that is, floor sealing devices for doors, and in particular it refers to devices that can be applied outside the ledges of such doors.
As known, draught excluding devices for doors comprise a channel-shaped section bar wherein there is mounted a mobile member capable of moving upwards and downwards, to and fro the floor under the door. The mobile member carries at least one seal intended to abut against the floor when the member is lowered, and at least at one end it is provided with a pushing member intended to engage with a respective door jamb to make the mobile member move downwards and consequently abut the seal against the floor when the door is closed. Moreover, at the end opposed to the pushing member, the mobile member exhibits an abutment means that abuts against a stop provided into the channel-shaped section bar so as to restrict the longitudinal movements of the mobile member and force it to lower when a force is applied to the pushing member.
If the device is applied outside the ledge base, for aesthetic reasons the channel-shaped section bar supporting the mobile member exhibits a rounded or asymmetric shape relative to its longitudinal axis. However, this is a disadvantage since it is not possible to apply the device to right- and left-opening door without distinction.
The same disadvantage may occur also in some cases when the device is applied into a seat obtained into the base of a door where, for construction constraints (such as the priority position of the lock on the floor, or the position of holes for securing the draught excluding device) or for the need of optimising the thermal and sound insulation (which, for example, requires the alignment of the draught excluding device seal with the door and/or frame seal), the draught excluding device must be fixed on a side of said seat and for practical reasons requires an asymmetric section of the channel-shaped section bar. Another similar case relates to doors already provided with a base seat for housing the draught excluding device mobile member, where said seat is necessarily asymmetric relative to its longitudinal axis, or where for semi-finished door storage purposes it is important not to define the opening direction of such doors in advance.
Purpose of the present finding is to remedy such disadvantages by proposing a single draught excluding device for doors which should be applied outside the ledge base, irrespective of the door opening side.
Another purpose of the finding is to provide a symmetric draught excluding device which should allow being introduced in one direction or in the opposed direction in the same way into an asymmetric profile already existing at the base of some doors or fixed to a side of a seat obtained in such doors, in any case in a side position relative to the ledge longitudinal axis.
Such purposes are achieved by a draught excluding device for doors according to the claims reported hereinafter.
Further details of the finding will appear more clearly from the following description, made with reference to the attached indicative and non-limiting drawings, wherein:

Fig. 1 shows a longitudinal section view of a draught excluding device according to the finding;
Fig. 2 shows a vertical section view of the device;
Fig. 3 shows a transversal section view of the device at the level of the stop;
Fig. 4 shows a transversal section view of the device at the level of a stop block;
Fig. 5 shows the device applied outside a door; and
Figs. 6 and 7 show a transversal section view of two examples of draught excluding device applied inside a door.

The draught excluding device 10 as described with reference to Figs. 1 - 5 is especially intended to be applied outside the base of a ledge 11 of a door. As known, it comprises a channel-shaped support section bar 12, substantially shaped as an upturned U, wherein there is inserted a mobile member 13 capable of moving upwards and downwards to and fro the floor, thanks to conventional means connecting said mobile member to the support section bar 12. Such connecting means are inserted and held into parallel sliding tracks 25 delimited by guiding edges 25' obtained longitudinally on the inside faces of the sides of the support section bar 12.
The mobile member carries at least one seal 14 intended to abut on the floor when the mobile member 13 is lowered, and at at least one end it is provided with a pusher 15 intended to engage with a respective jamb 11' of the door to make the mobile member 13 lower and consequently make seal 14 abut against the floor.
Moreover, at the end opposed to pusher 15, the mobile member 13 exhibits an abutment member 16 intended to abut against a stop 17 provided into the support section bar 12 so as to restrict the longitudinal movements of the mobile member and force the latter to lower when a force is applied to pusher 15.
According to the finding, two stop blocks 18 are inserted into the support section bar 12 and locked at a suitable distance from one another. Such blocks 18 rest on edges 25' and are therefore arranged in the top side 12' of the support. The blocks are constrained into position for example by tongues or projections 19 obtained in the section bar itself. Stop 17 is inserted in the portion of section bar 12 comprised between said stop blocks 18 and it is capable of longitudinal movements, since it is guided by edges 25'. Stop 17 exhibits a head in the top portion 12' of the support section bar, and which is therefore intended to alternately abut against the stop blocks, and a bottom appendix 21 extending in the bottom portion 12" of the section bar and serving as stop for the abutment member 16 of the mobile member 13.
According to the door opening direction, stop 17 is placed against one of the two stop blocks, thereby allowing the device operation without having to turn the section bar by 180°.
It should be noted that the head of stop 17 exhibits a breakage 20' at the means for fixing the stop blocks 18, so as to not interfere with them and make stop 178 slide freely before fixing both blocks.
The stop blocks 18 may also be used for receiving screws 22 for securing the device to the door. A window 23 will therefore be obtained in the support section bar at each block, closable by a special insert 24.
With reference to Figs. 6 and 7, the device under discussion is especially advantageous also in some cases of insertion into a seat 25 or in an aluminium section bar 26 already provided at the base of a door ledge. For example, if the draught excluding device cannot be introduced/extracted through a side door opening, the channel-shaped section bar 12 may exhibit a tab or side top extension 27 to be tightened to the ledge from the bottom - Fig. 6. Also in this case the section bar is therefore asymmetric.
On the other hand, Figure 7 shows a door having one side with the aluminium section bar 26 configured for receiving the mobile member 13 of the draught excluding device, and the other side made of wooden. In this case, the proposed device allows obviating the asymmetric structure of the door itself.
Finally, it should be noted that in place of the stop blocks 18 it is possible to use the same heads of the screws used for securing the support section bar 12 to the ledge, or similar means as abutment means for stop 17.
