DETAILED DESCRIPTION OF THE DRAWINGS

(7) Reference is first made to FIG. 1 in which the reference numeral 1 indicates a building structure provided with an opening 11 arranged to receive a building component 2, shown as a window here, and encircled by a supporting structure 111 arranged to receive the fixing means of the building component 2, several frame-adjustment bolts 22 among other things. The frame-adjustment bolts 22 are provided with bolt heads 221 and are screwed into bolt holes 214 extending through the frame 21 of the building component 2 from the external side face 211 of the frame 21, the frame-adjustment bolts 22 being provided, in end portions remote from the bolt heads, with recesses, not shown, arranged for engagement with an adjusting tool 4 inserted through bolt-hole mouths 214′ in the internal side face 211′ of the frame 21.

(8) The building component 2 comprises an inwards facing edge face 212 and an outwards facing edge face 212′.

(9) A carrying-handle arrangement 3 is attached to a lower portion of each external frame side face 211 by means of a selection of frame-adjustment bolts 22. Alternatively, the carrying-handle arrangement 3 may be attached by means of ordinary fixing bolts (not shown) which do not have any other function than holding the carrying-handle arrangement 3.

(10) Reference is now made especially to FIGS. 2 and 3. The carrying-handle arrangement 3 includes a grip portion 31 formed as a bow-shaped handle projecting from an outer side edge 32a of a plate-shaped attachment portion 32. The attachment portion 32 is provided with two cut-outs 321 arranged to receive the heads 221 of frame-adjustment bolts 22 for locking engagement. A first cut-out portion 321a is wider than a second cut-out portion 321b, the first cut-out portion 321a being arranged, in a position of application, above the second cut-out portion 321b, for example in the shape of a keyhole as shown in FIG. 2, in order thereby to provide space for the bolt head 221 to be passed through in the first cut-out portion 321a and prevent the bolt head 221 from passing when the frame-adjustment bolt 22 extends through the second cut-out portion 321b. It is obvious that other cut-out shapes lie within the scope of the invention as well. The distance between the cut-outs 321 is adapted to the distance between two adjacent frame-adjustment bolts 22. In FIG. 2, a lower frame adjustment bolt has been removed for the sake of exposition.

(11) When the carrying-handle arrangement 3 is being fitted to the external side face 211 of the frame 21, the carrying-handle arrangement 3 is oriented in such a way that the narrow portion of the cut-out 321 is facing downwards. The attachment portion 32 is brought in over the corresponding bolt heads 221, which, at this stage, are lying with a clearance to the external side face 211. The frame-adjustment bolts or the fixing bolts 22 are tightened to prevent the carrying-handle arrangement 3 from being displaced in the cut-outs 321. The operation is repeated to fix further carrying-handle arrangements 3 to other portions of the frame 21. The building component 2 has now been prepared to be moved, the carrying-handle arrangements 3 providing handles well suited for lifting the building component 2.

(12) When the building component 2 has been positioned in the opening 11 of the building structure 1 and secured, the carrying-handle arrangement 3 can easily be removed by the fixing bolts 22 being loosened and the attachment portion 32 being pulled out of engagement behind the bolt heads 221. At this stage, the adjusting feature of the frame-adjustment bolt 22 particularly comes into its own, as it can be loosened by the engagement of the adjusting tool 4 with the recess, not shown, of the frame-adjustment bolt 22 via the bolt-hole mouth 214′ completely independently of the clearance between the frame 21 and the adjacent supporting structure 111.

(13) When required, two carrying-handle arrangements 3 may be attached to the same set of fixing bolts 22, see FIG. 4. Owing to the flexibility of the attachment portion 32, a grip portion 31′ projecting outwards may be pressed towards the centre of the building component during the insertion of the building component 2 into its opening 11, in order not to prevent the fitting of the building component 2.

(14) Alternatively, the carrying-handle arrangement 3 may be provided with two grip portions 31, 31′ projecting in opposite direction, see FIG. 5, one at each opposite outer side edge 32a of an attachment portion 32, which, in this embodiment, has been extended in relation to an attachment portion 32 provided with one grip portion 32 according to FIGS. 1-4.
