FASTENING MEANS, PREFERABLE FOR DOORS, WINDOWS OR THE LIKE

Abstract: Fastening means preferable for door- and windowframes or cases comprising an adjusting screw (4) attachable in a wall opening (8) or the like and a locking means (2) cooperating with said screw and fixable in said frame (7) or the like. According to the invention the locking means consists of a locking plate (2) attachable against the end border (9) of said frame (7) faced towards the edge part (14) of the wall opening (8), from the fastening plate (10) of said locking plate (2) a locking means (11) protrudes allowing a selectable connection in a longitudinal direction of said frame (7) to a snap means (1) provided at the upper part (12) of the adjusting screw (4) and provided to engage the locking means (11).

Description: Fastening means, preferable for doors, windows or the like The present invention relates to a fastening means preferable for door or window frames or cases, said means comprises an adjusting screw attachable in a wall opening or the like and a locking means cooperating with said screw and being fixable 5 in said frame or the like. Up to now exsisting fastening means on the market which are intended for frames or the like today often consist of screw means comprising a screw extending through the frame and con¬ tinue into the edge of that opening in the wall, in which the 0 frame is going to be fixed. The screw is provided with an out¬ er threaded part for a casing which is intended to be screwed by aid of its outer thread into a bore made through the frame in a. direction to edge part of the opening. The screw of the fastening means can be adjusted after the mounting in the edge 5 part of the wall opening in such a way that the frame is dis- placeable towards and out from the edge part owing to the fact that the screw is rotated to the one or the other direction. The casing is now situated screwed into the position in the frame. When the frame is adjusted to its proper position in Q . the wall opening the bores in the frame made for the screws are hided by cover plates of plastic. Another common way is to wedge up the frame in a vertical and horizontal direction and at the same time fix the same by screws and nails. The object of the present invention is to provide a fastening 5 means of the type described in the beginning said means elimi¬ nates the drawbacks exsisting in the fastening means previ¬ ously known while it serves its purpose in an excellent way at the same time and owing to its simple structure is cheep to produce. Essentially distinguishing for the invention is 0 that the locking means consists of a locking plate attachable against the end border of said frame faced towards the edge part of the wall opening, from the fastening plate of said locking plate a locking means protrudes allowing a selectable connection in a longitudinal direction of said frame to a snap: means provided at the upper part of the adjusting screw and provided to engage the locking means. Due: to the invention there is now achieved a fastening means which do not need any bore making through the frames or the 5 cases-, which are to be mounted. Further no wedges must be used during the mounting but after having screwed in the adjusting screw of the fastening means on predetermined positions around the edge part of the wall opening the frame, on which during an earlier stage the locking plates of the fastening means have 10.. been e g screwed on against the end border of said frame, in a simple way can be lifted into the proper position in such a way. that the locking means protruding from the locking plates hook—up the fixing and/or snap means protruding from the upper part- of the adjusting screws. After that a further correction 15 can be carried out of the fixing of the frame in the wall open¬ ing: if necessary by turning around the adjusting screws, which are; easily accessible from one or the other side of the frame by a wrench depending on in which way the the locking plates have been mounted. Owing to that the locking plates have a 20 length, in the circumference direction of the frame which is larger than the hook-up area of the snap means in relation to the. locking means of the locking plates the location of the adjusting screws is not critical laterally, said fact makes the^ mounting essentially easier. The location of the adjust- 5 ing screws the deep direction on the contrary must be more exact., but this often does not involve any difficulties. The invention will now be described in detail with reference to the accompanying drawings, on which Fig„ 1 illustrates an embodiment of the invention in which the 0: fastening means is illustrated in a schematic side view having the locking means of the locking plate mounted in that direction admitting an adjustment of the screw from the left side. Fig. 2 illustrates a view in a larger scale of the adjusting 5 screw from above having a snap means protruding from the upper part of said screw and Fig. 32 illustrates a plan view of the locking plate attachab against the end border of the window frame alternative in the wall opening and cooperating with the adjustin screw and its snap means. As can be seen from Fig. 1 the fastening means according the preferable embodiment of the present invention is intended to be attached between the end border 9 of a door or window frame 7 and an edge part 14 of a wall opening 8. The illustrated fastening means comprises of a locking plate 2 intended to be attached e g by screws 22 in the end border 9 of the frame 7 and a. snap means 1 connectable to the locking plate 2, said snap means is supported by and fixed to a adjusting screw 4 in the edge part 14 of the wall opening 8. In the preferred embodiment of the present invention the snap means 1 is turnably fixed on the adjusting screw 4 but can of course also be formed in a different way e g cylindrically round and also being rigidly fixed to the upper part of the screw 4. Alternatively the adjusting screw 4 also can be fixed to the end border 9 of the frame 7 and the locking plate 2 can be fixed to the egde part 14 of the wall opening 8. The snap means 1 , which can be turnable around the adjusting screw 4 in a plane as in the example illustrated and is mainl located perpendicularly to the longitudinal direction of the ' adjusting screw 4, is provided between a supporting means 5 and the head 13 of the adjusting screw at an μpper part 12 of said adjusting screw 4. As can be seen from Fig. 1 and 2 the snap means 1 comprises a tongue formation 15 protruding from a locking and guiding shoulder 6, said formation is intended for a lockable cooperation and connection with a hook formed locking means 11 protruding from the locking plate 2. In that case a locking and guiding shoulder 6 is used the tongue formation 15 is, as can be seen from Fig. 1, displaced in its position via said shoulder 6 at the upper part 12 of the ad- justing screw 4 a distance mainly corresponding to the height of the screw head 13. From Fig. 2 can be seen that the snap means 1 can be provided with a tongue formation 15 having sides 20,21 converging in a direction towards its free end 3, said free end is bevelled for making the insertion of the tongue formation 15 into the hook formation of the locking means 11. Alternatively the tongue formation 15 can be round formed having friction elements e g in the form of quills f r cooperation with the locking means 11 of the locking plate 2. The locking plate 2 has a fastening plate 10 from which the locking means protrudes. The locking means 11 is formed by a branch 18 extending in parallel to and at a predetermined distance from the fastening palte 10 for forming a locking gap 17, in which the tongue formation 15 of the snap means 1 is. insertably lockable. The locking occurs when the free longitudinal edge 19 of the branch 18 contacts the locking and guiding shoulder 6 of the snap means 1. The width of the locking gap 17 mainly corresponds to the thickness of the tongue formation 15 of the snap means 1. The tongue formation 15 is locked in the locking gap 17 by aid of a locking slot 16 extending across the longitudinal direction of the tongue formation 15, said slot is cooperating with a bulge 23 pro¬ truding inwards in the locking gap 17 from the branch 18 of the locking means 11. In Fig. 3 is illustrated how the locking plate 2 look like ' in a plan view in a greater scale. The length of the lock¬ ing plate 2 is selectable but suitable ought to be two or - three times the length of the largest width of the snap means 1.. As can be seen from the embodiment illustrated the locking plate 2 suitably can be fixed by four screws 22. The locking plate 2 turned to the left in the preferred case (Fig. 1) can of course also be mounted to the right depending on if the adjustment of the fastening of the frames or case in the actual wall opening shall be made from the inside or the outside of the frame.
