Definitions

• the present invention relates to a door-jamb arranged in a door-opening between two adjoining rooms, the door-jamb being designed so that it allows ventilation between the rooms.
• Ventilation between two rooms, separated by a wall with a door has traditionally been achieved by a recess in the top rail of the jamb in such a way that a longitudinal gap is created between the top edge of the pivotable door-leaf, when the door is in a closed position, and said top rail of the door-jamb.
• This solution yields only a small surface for the air to flow through between the two rooms, and the recessed ventilation gap is clearly visible from both sides of the wall.
• the ventilation gap can be said to break up the otherwise aesthe ⁇ tically clean general appearance of the door-jamb.
• the German publication DE 1 143 623 shows another solution of ventilation where a longitudinal, rectangular opening has been taken up above the top rail of the door-jamb.
• the opening is covered by a hatch which, when necessary, can be opened and closed by means of a pull-rod in connection with a handlebar at one of the vertical stiles of the door-jamb.
• this solution has an almost devastating effect on the appearance of the door-jamb. It does, however, provide a larger surface of ventilation compared to the aforementioned recessed gap. Ventilation has also been achieved by means of built-in fans in the door-jamb, which is illustrated by the French patent No.
• 1,312,749 which in the drawings relates to a window-jamb provided in the stiles and rail of the door-jamb with fans in longitudinal opening covered with a grid net.
• a design surely provides for effective ventilation, but is virtually unthinkable from a mass-produc ⁇ tion point of view where the consistant use of standard items is strongly urged.
• the ventilation openings can easily be detected by the eye from both sides of the wall.
• a better and more industrially applicable solution is illustra ⁇ ted by the Swedish publication No. 6700190-9.
• This solution can be adapted to established standard dimensions for door-jambs, and the jamb is provided with detachable profiled architraves.
• the top rail of the jamb has recessed openings facing toward the edge-surfaces of the wall-opening, which creates free spaces between the jamb and the opposite edge-surface of the wall.
• harrow perforations are taken up in order to allow airflow via the openings in the jamb.
• the ventilation openings are clearly visible in the top section of the door-opening, this time in the architraves.
• the jamb can nevertheless be of standard dimension whereby extensive measures like for instance cuttings in the existing door- opening can be avoided, which is not the case in the afore ⁇ mentioned ventilation opening above the top rail of a jamb.
• the openings creates a free space toward the edge-surface of the wall-opening, a space which in the real situation is enlarged since there is often a gap between the jamb and the edge-surfaces of the wall-opening.
• the gap not counting the recesses in the described design, varies between a few mm to about 30 mm.
• the jamb according to SE 6700190-9 with its recesses toward the edge surfaces of the wall-opening only allows for wedge-blocks to be wedged in at the remaining portions of the jamb still having their full thickness.
• Another way to fit a door-jamb into a wall-opening is to fill said gap with polymer foam which is then allowed to solidify. This method was widely used during the 1970:s and provided a quick and accurate fitting of the door-jamb. Originally, polyurethane foam was used to this end, a foam that later proved less suitable because of environmental drawbacks, and as a result the method virtually died out. Today, however, new environmentally suited foam materials have been developed which again makes this method very interesting for mounting jambs.
• Foam fitting can not be carried out together with the jamb in the aforementioned patent SE 6700190-9, since the foam will when also fill the recesses toward the edge-surfaces of the wall opening, and completely seal these, with the result being zero ventilation.
• a further drawback of this design is that the recesses, the way they are shaped, inevitably means a considerable decrease in the structural strength of the jamb.
• a uniting factor of before know solutions of ventilation is, as has already briefly been mentioned, that the externally visible, main-ventilation openings are facing perpendicularly to the plane of the wall surface and thereby in the direction of passage of the door-opening. Apart from the fact that this ruins the appearance from an aesthetic point of view, it also results in a less effective sound-insulation between the two rooms.
• the object of the present invention is to alleviate the above problems by providing a ventilated door-jamb with architraves, having preserved structural strength, preserved option to use existing methods of fitting when mounting the jamb, and an aesthetically preserved appearance along with maximum sound- insulation.
• the present invention provides a door-jamb in a door-opening, for ventilation between adjoining rooms, comprising vertical stiles and a lateral rail having a passage for airflow, and architraves having at least one opening communicating with said passage.
• the invention relates specifically to that the passage, in a direction toward the edge-surfaces of the wall-opening, is delimited by a rear board, connected to the rest of the stiles and rail at at least one side of the passage.
• the architraves are mounted on the stiles and rail of the jamb.
• Each opening in the architraves is positioned in a section of the architrave facing away from the jamb, in a direction toward the edge-surfaces of the wall- opening, at the underside of an overhanging part of the section.
• the openings of the architraves are slit- shaped. Since the opening of the architraves are positioned under an overhanging part of said section, a so called sound- trap is obtained which provides effective sound-insulation.
• said passage consists of a slit-shaped opening in the jamb leading out to both sides of the jamb. Furthermore, the jamb has a plurality of passages in each stile and rail, yielding an increased surface of ventila ⁇ tion.
• Fig. 1 is a view of a door-jamb according to the invention situated in a door opening.
• Fig. 2. is a cross-sectional view on line II-II in Fig. 1 of a stile with architraves.
• Fig. 3 is a broken perspective view of an architrave accor ⁇ ding to the invention. Best mode of carrying out the invention:
• a door-jamb 1 is mounted in a wall 2 with a wall-opening 3.
• the jamb 1 consists of two vertical stiles 4 in contact with the vertical edge-surfaces 5 of the wall opening 3, and a lateral rail 6 in contact with the lateral edge surface 7 of the wall-opening.
• architraves 8 are fitted in herefore intended slots 9.
• the stiles 4 and the rail 6 are, as shown in Fig. 2, composed of composite elements with internal layers 10 of wood-fiber material, which layers are partially surrounded by a cover-layer 11.
• the wall 2 is diagrammatically shown in Fig.
• a broken section of the openable door- leaf 14 is shown with a dot-lined line in the closed position, whereby it is in contact with the ledge section 15 of the stile 4.
• the passage 17 is delimited in a direction toward the edge surface 5 of the door opening 3 by a rear board 18, belonging to the jamb 1.
• the rear board 18 being con ⁇ veniently made of wood-fiber material and connected to the rest of the stiles 4 with distance elements 19 on each side of the passage 17.
• a plurality of such passages 17 are provided in the stiles 4 and the rail 6 of the jamb 1.
• the passages 17 consist as is clearly shown i Fig. 1 och 2, of slit-shaped openings in the stiles 4 and the rail 6 leading out to both sides of the jamb. Since passages 17, as mentioned above, are provided in the stiles 4 and the rail 6, a much increased surface of ventilation is created compared to previously known solutions where ventilation mainly takes place in the top section of the wall-opening at the top rail of the jamb.
• the architraves 8, being mounted in slots 9 in the jamb l, consist of thin plastic profiles and are provided with openings 20 communicating with the passage 17 via the airflow.
• the openings 20 of the architraves 8 lead out in a direction parallel to the sides 12, 13 of the wall 2 and are situated on the underside of an overhanging part 21 of a section 22 facing away from the jamb 1 in a direction toward the edge-surface 5 of the wall-opening.
• the openings 20 are rectangularly shaped and situated along the complete length of the architraves 8, whereby the separate openings 20 are separated from each other by protrusions 23.
• the special positioning of the openings 20 together with the space 24 created on the inside of the overhanging part 21, thus consti ⁇ tute a so called sound-trap where sound-waves passing from one room to another are damped to a considerable extent.
• a jamb 1 is thus provided, which stiles 4 and rail 6 display minimum weakening of the structural strength compared to a corresponding jamb without ventilation facilities.
• this solution one also preserves the option to use existing fitting methods in the wall-opening 3 when the jamb 1 is mounted without the ventilation effect being negatively affected.
• aesthetically pleasing architraves 8 are provided displaying clean surfaces, seen from the outside, without disturbing perforations for ventilation.
• the present invention is not limited to the embodiment described hereinabove, and it can naturally be varied within the scope of the accompaning patent claims.
• the passage 17 in the jamb 1 can thus for instance be achieved by milling or alternatively as a plurality of holes. This goes also for the openings 20 of the architraves 8 which can of course also be milled out or be of circular shape. Thus, there is no con ⁇ finement to rectangular openings as shown in the drawings.
