Description

[0001] The present invention relates to a fitting assembly for pivotal connection of a sash component with respect to a main frame component of an openable window structure, comprising elongate first and second fitting members for connection with opposed side members of the main frame and sash components, respectively, said second fitting member being pivotally connected at a first end with a slide member fitted in said first member for sliding motion through part of the length of the first fitting member from a first end thereof, and a stay member having a first end pivotally connected with the first fitting member adjacent a second end thereof and a second end pivotally connected with the second fitting member at a distance from the second end thereof to allow pivotal movement of the sash component between a closed position of the sash component, in which the first and second fitting members and the stay member extend in overlying substantially parallel relationship and any position within a range of opening positions defined by the pivotal connections of the fitting and stay members.

[0002] Fitting assemblies of this kind are commonly used for assembling the sash and main frame components of top-hung openable window structures.

[0003] In such assembling operations, by which the first and second fitting members are connected with opposed side member of the sash and main components at one vertical side thereof, difficulties are occasionally encountered in obtaining a desired accurate positioning of the sash component within the opening provided by the main frame component due to tolerances in the production of the window components and/or distortions imparted to the main frame component during its installation in a window opening in a building wall. By distortion of the positioning of the sash component the side, top and bottom members thereof may become out of alignment with the opposed side, bottom and top members of the main frame component and, at worst, it may become impossible to fit the sash component correctly within the main frame component.

[0004] It is the object of the invention to provide a simple and user friendly adjusting mechanism to eliminate this problem.

[0005] According to the invention this object is accomplished by a fitting assembly of the kind defined, which is characterized in that adjusting means is provided at the second end of the first fitting member for adjustment of the position of the pivotal connection of the first end of the stay member with the first fitting member.

[0006] Thereby, an out of alignment distortion between the sash compent and the main frame component may in most cases be easily remedied by adjustment of the adjustment means of the fitting assembly at one and/or the other vertical side of the sash and main frame components. By this adjustment the position of the pivotal connection of the first end of the stay member with the first fitting member may be sufficiently adjusted to restore a correctly aligned mounting of the sash component with respect to the main frame component.

[0007] Advantageous and preferred additional features of the fitting assembly are stated in the dependent claims.

[0008] Thus, in a preferred embodiment the adjusting means may comprise a first adjusting member adjustably fitted in the first fitting member adjacent the second end thereof and pivotally connected with the first end of the stay member, and a second adjusting member fixed with the second end of the first fitting member, the second adjusting member being providing with adjustable contact means adapted for contact by an end contact part provided by the first adjusting member.

[0009] Preferably, the end contact part may be provided by a first end section of the first adjusting member, which includes the pivotal connection of the first adjusting member with the first end of the stay member, the first adjusting member comprising a second end section offset from said first end section and providing means for securing the first adjusting member with respect to the first fitting member.

[0010] In a preferred embodiment the second adjusting member may comprise a brick-like member providing a blind receptacle with an entrance opening in one end face of the brick-like member for receiving the end contact part of the first adjusting member, said contact means being provided by an adjustable contact member at the bottom of said receptacle.

[0011] Preferably, the contact means is provided by an adjusting screw screwed into the blind receptacle from an end face of the brick-like member opposite to said one end face.

[0012] In the following, an embodiment of the fitting assembly according to the invention will be explained in greater detail with reference to the schematic drawings, in which

Fig. 1 is an exploded view of the fitting assembly;

Fig. 2 shows a section of the fitting assembly as illustrated in fig. 1 at a larger scale; and

Figs. 3 and 4 are perspective views corresponding to figs. 1 and 2, respectively, of the fitting assembly in its assembled condition.

[0013] As shown in the drawing the adjustable fitting assembly according to the invention comprises a first fitting member 1 for connection the inner side of a vertical side member of the main frame component of a top-hung window structure and a second fitting member 2, which is adapted for connection with the sash component of the window.

[0014] At a first end, the second fitting member 2 is provided with a pivot member 3 for pivotal connection with a slide member 4 fitted in the first fitting member 1 at a first end thereof for sliding motion through a part of the length of the first fitting member 1.

[0015] Between the first and second fitting members 1 and 2 a stay member 5 is provided, which is pivotally connected at a first end by pivot means 6 with adjusting means generally designated by 7, which is provided at the second end of the first fitting member 1 and will be further explained in the following.

[0016] At its second end the stay member 5 is provided with pivot means 8 for pivotal connection with the second fitting member 2 at a distance from a second end thereof.

[0017] As more clearly illustrated in fig. 2, the adjusting means 7 comprises a first adjusting member 9, which is adjustably fitted in the first fitting member 1 adjacent the second end thereof and is provided with the pivot member 6, with which the first end of the stay member 5 is pivotally connected, and a second adjusting member 10, which is fixed with the second end of the first fitting member 1 and provides adjustable contact means adapted for contact by an end contact part 11 of the first adjusting member 9.

[0018] The end contact part 11 is formed by a first end section 9a of the first adjusting member 9, which includes the pivot member 6 for pivotal connection of the first adjusting member 9 with the first end of the stay member 5. The first adjusting member 9 comprises also a second end section 9b, which is offset from the first end section 9a by a shoulder portion 9c, and by means of which the first adjusting member 9 may be firmly secured with respect to the first fitting member 1, once the first adjusting member 9 has been adjusted into a correct position with respect to the first fitting member 1.

[0019] Adjustment of the first adjusting member 9 into a desired adjusted position of the pivot means 6 is accomplished by means of the second adjusting member 10, which comprises a brick-like member 12 providing a blind receptacle with an entrance opening in one end face 13 of the brick-like member for receiving the end contact part 11 of the first adjusting member 9.

[0020] At the bottom of the blind receptacle in the second adjusting member 10 contact means for the end contact part 11 of the first adjusting member 9 is provided by an adjustable contact member, preferably in the form of an adjusting screw 14 screwed into the blind receptacle from the opposite end face 15 of the brick-like member 12.

[0021] In the illustrated embodiment the fitting assembly according to the invention is designed mainly for use with window structures having main frame and sash components made up of wood profiles and the first and second fitting members 1 and 2 and the first and second adjusting members 9 and 11 is provided with holes for conventional screw connections. Specifically, to accomplish a desired range for adjustment of the position of the pivot member 6 with respect to the first fitting member 1 an elongate screw hole 16 is formed in the second offset end section 9b of the first adjusting member 9.

[0022] By offsetting the first end section 9a of the first adjusting member 9 from the second end section by means of the shoulder portion 9c the pivotal mo-vability of the stay member 5 with respect to the first fitting member 1 by the pivot member 6 is secured.

[0023] In use of the fitting assembly the second fitting member 2 is first connected with a vertical side member of the sash component of the window structure, which at this stage is separated from the main frame component. To secure correct positioning at the end of the sash side member joined with the top member of the sash component the second fitting member 2 may be formed with a projecting angular arm 17, which may be connected with the sash top member close to its corner junction with the side member.

[0024] The first fitting member 1 may now be connected with the vertical side member of the main frame component intended to be opposed to the sash side member, with which the second fitting member 2 is connected, the first fitting member 1 being positioned at the main frame side member to have its upper end 18 placed in contact with the top member of the main frame component.

[0025] If a distortion or misalignment of the sash component with respect to the main frame component is observed, correction may be accomplished by the adjusting mechanism provided by the invention, by which the position of the pivot member 6, by which the stay member 5 is pivotally connected via the first adjusting member 9 with the first fitting member 1, is adjusted. The adjustment is made by means of the adjusting screw 14 acting on the end contact part 11 of the first adjusting member 9, whereby the position of the first adjusting member 9 may be displaced within the range provided by the elongate screw hole 16, through which the thus adjusted position of the first adjusting member 9 with respect to the first fitting member 1 may be secured. Typically the displacement range thus provided for adjustment will be a few millimetres.
