Description

[Detailed description of the invention] jamb for a door or window The present invention relates to a door or window jamb installed in an opening in a wall.

Technical background In the modern door and window industry, the use of composite materials as a substitute for solid wood is next. It has increased in number. By introducing composite materials, materials can be improved without reducing product quality. material and manufacturing costs can be reduced. Several pieces of bonded fiberboard or paper The properties of the material of the composite element made of particle board can be changed by changing the composition and material ratio of the composite material. It can be easily adjusted in each desired direction by On the other hand, solid wood When used in products, the properties of the material are determined in advance by selecting the type of wood. can be determined.

When using composite materials, the composite element is often coated with an exterior surface layer consisting of The purpose of the required surface layer is, on the one hand, a resistant protective coating that prevents abrasion and surface damage. On the other hand, the purpose is to give the composite device an attractive appearance. Ru. The surface of the armored composite element can be made considerably stronger, making it much stronger than the counterpart of the solid wood element. It can be more durable than other surfaces. Depending on different requirements for appearance , the sheathing can be, for example, wood veneer, plastic or paper material. However However, for example, when cladding cheap, low-quality wood with expensive wood veneer, solid It becomes necessary to attach an exterior to a product made of wood.

Technical issues In known technology, edge joints of two abutting jamb elements are mass-produced. to ensure that the jamb cannot be seen from the outside as a composite product with exterior covering. It is practically impossible to do so. It is easy to see that the composite element is equipped with an exterior. It is desirable that the product not be exposed upon close inspection, since the product is made of solid wood. This is because it is necessary to closely resemble the appearance of a timber jamb as closely as possible.

Traditionally, there have been no advantageous solutions for edge-joining composite jamb elements in this way. It was. The reason for this is that when the exterior surface layer is applied to the edge of the product, It is in the rounded part necessary for. This is because sharp edges cannot be tolerated in the surface layer. This is because stretching and cracking inevitably occur. For example, one jamb element The base of the jamb of the present invention is recessed to receive the jamb element abutting the base. This principle is previously known from Swedish Patent Publication No. 7115940-4. Before This publication relates to the prior patent of the applicant. As shown in this prior patent Pillars are traditionally made from solid wood, and the structure has rounded edges. 2 A seam gap is created where the two jamb elements abut. In this case, the rounded edge The cross-section of the jamb element can be partially seen from the outside. This way The structure consists of solid wood without any surface treatments such as paint or varnish. Acceptable for jambs and common in the market for jambs with rounded edges. means a compromise. However, partially exposing the cross section of the jamb element The jamb is totally unacceptable. This is because the exposure is on the exterior surface. This is because it reveals the layers and composition of the official residence. Additionally, the exposure is made of solid wood jambs. Not suitable if the jamb elements are painted with dark paint, e.g. dark gloss paint. It is. In that case, it is also necessary to treat the visible cross section of the jamb element. It is from. This is because this cross-section necessarily takes on a different tone than the rest of the surface. This is because it will lead to an increase in The reason for the difference in color tone is due to the edge wood exposed in the cross section. This is because the surface properties and fiber orientation are different from other parts.

The object of the present invention is that, excluding the stop surfaces of the stop bars, the ends of the two jamb elements that abut are A round shape having a structure in which the edge joint does not expose the cross section of the jamb element. The above-mentioned problems can be solved by providing door and window jambs with built-in parts. There are many things.

Composition of the invention The above object is achieved by the present invention, in which the end of one of the jamb elements to be joined is A type of wall opening that is recessed to receive the transverse end of the other jamb element. This is accomplished by a door or window jamb at the mouth. This jamb can be opened The jamb element has a rounded edge portion. present invention especially where one jamb element is adjacent to the rounded edge of the other jamb element. A width difference consisting of at least equal to the radius of the rounded edge part with respect to the other jamb element the narrow side of the jamb element and the narrow side of the stop face facing away from the releasable element. It relates to a jamb that is characterized by having two sides.

In a preferred embodiment, the jamb elements are sheathed with a surface layer. Preferably the jamb element is Consists of a bonded plate of composite material located inside an armored surface layer.

Brief description of the drawing The invention will now be explained with reference to the illustrated embodiments. Same for corresponding parts in each diagram Reference numbers are provided.

FIG. 1 is a side view of a portion of the jamb of the present invention.

2 is a perspective view of a portion of the jamb of FIG. 1; FIG.

FIG. 3 is a sectional view taken along line IV--IV in FIG.

FIG. 4 shows a joint of a known jamb with a jacketed jamb element according to the invention shown in FIG. 3; It is a similar cross-sectional view.

BEST MODE FOR CARRYING OUT THE INVENTION In the embodiment shown in FIG. 1, the reference numeral 1 designates a jamb consisting of jamb elements 2a, 2b. show. Said jamb element is provided with a stop bar 3 .

One of the jamb elements 2b to be joined is connected to the edge of the other jamb element 2a. Recessed to receive portion 5. Therefore, the vertical jamb element 2a is as shown in the figure. It has been cut across, and the retaining bar of this jamb element has water as shown by the broken line 6 as shown in the figure. It engages the flat jamb element 2b. The jamb elements 2a and 2b are shown in Fig. 1.2.3. As shown, it has a rounded edge portion 8. - of one of the jamb elements 2a shown in FIG. The cross section shows that the jamb element 2a consists of four superimposed timber boards 10. . The board may be a board made of a combination of composite materials, and one of the boards 10 holds the stopper 3. Form. The joined plate 10 has a surface layer surrounding most of the jamb elements 2a, 2b. 12, but the rear surface 13 is not entirely surrounded by this surface layer.

The vertical jamb elements 2a typically have a greater depth or width than the horizontal jamb elements 2b. have. Similarly, the stop bars have a greater width than the corresponding horizontal stop bars 3. width difference is at least equal to the radius of the rounded edge portion 8. Because of this relationship, At the edge joint of the jamb 1 between the matching side branch elements 2a and 2b, these side The cross section of the branch element cannot be seen from the outside. This is shown in the joining area 16 in the figure. It is clearly recognized that

FIG. 4 shows a known jamb edge joint. Comparison with the edge joint of the present invention in Fig. 3 In other words, the joining side elements 2a and 2b have the same width. this thing will stop The same applies to the crosspiece 3. This differs from the embodiment of the present invention, and A cross section of the children 2a, 2b is partially exposed in the joining area 16 and inspected closely by eye. This means that the composite structure with the exterior of the jamb 1 is exposed.

According to the embodiment of the invention shown in FIG. 3, a stop for the releasable element is constructed. The narrow surface or stop surface 17 of the stop bar 3 is similar to the corresponding stop surface 17 of the other side branch element. are in the same plane. Therefore, the region 18 where both stop surfaces 17 come into contact is a cross section of the side branch element. is the only bonding area exposed (corresponding to that in FIG. 4). But this example This is necessary in order to provide a suitable sealing effect on the openable elements.

The above embodiments of the invention also have edge joints that meet the main requirement of providing an aesthetic appearance. Provide a morning post.

The present invention is not limited to the above-mentioned areas, but various changes may be made within the scope of the present invention. can be done.
