Abstract

In the filling out with jointing material of the slot between window frames or door frames and an opening in the wall of a building, it is well-known for a 'back-stop' for a final jointing to be introduced into this slot, namely by the insertion of a jointing string in the slot. With the invention, this insertion can easily be effected while achieving a constant and expedient depth, in that for the pressing-in of the string use is made of an implement with a handgrip to which is connected a part for support contact against the front of the frame, and a pressing-in part which can hereby be extending into the slot and can thus press the string in to precisely the desired depth. The two parts are preferably integrated in a profiled roller with a cylindrical contact part and a protruding disk part for penetration into the slot.

Description

AN IMPLEMENT FOR MOUNTING A JOINTING STRING IN A SLOT

The present invention relates to an implement for use in connection with jointing work, especially in connection with the mounting of insulating jointing string in slots between wall openings and window frames or door frames. Such slots can be more or less filled out with filling compounds or foaming material, but it is common that from the outer side of the slot there is inserted a "back-stop" in the form of jointing string which is pressed a short way into the slot, hereby forming a bottom in the free outer slot, which must subsequently be filled out with a jointing compound.

It is reasonably easy to press the said jointing string into the slot by means of a suitably narrow tool of some sort, for example a screwdriver, but if the person mounting the jointing string is not sufficiently attentive, the result can well be that the string extends in such a manner that it lies unnecessarily deep in some places, while in other places it can lie at an unsuitably shallow depth. In the first- mentioned case, an unnecessarily large amount of jointing compound must subsequently be used to finalise the jointing, and in the last-mentioned case there can be too little depth for the jointing compound to effect proper engagement in the walls of the slot.

With the invention it has been realised that the relevant work can be carried out both easier and more precise with use of a simple tool, this being in the form of a hand-held implement which has a grip with a contact part for contact against the front part of the frame which abuts up to the joint, and with a protruding pressing-in part which, by this contact, can be held extending into the joint.

With the use of such a special implement, the person mounting the jointing string will be able to carry out the work with increased uniformity of the inserted jointing string, in that the abutment against the outer side of the frame will stabilise the insertion depth in places where particularly great or particularly low resistance arises against the pressing-in of the string. If the implement is a stiff unit, the working depth of the pressing-in part will depend on the angle of the grip in relation to the outer side of the frame, i.e, it is prescribed that this angular position be more or less constant. However, it will be possible to avoid this limitation if an elongated element part is chosen as the contact part, and which supports itself against the outer side of the frame along a substantial part of its length or merely at opposite ends thereof, e.g. by use of a suitable slide-shoe or support roller. When it is this element part which carries the press- ing-in part, it can thus be pivotally connected with the grip, whereby its angular position will not have any influence on the pressing-in depth, simply providing that the user presses hard enough on the implement to be able to feel that the contact part is in plane abutment against the outer side of the frame.

This has given rise to a preferred embodiment of the invention, namely where the implement comprises a hand-guided roller which can turn freely on a radially-extending roller shaft, and which is profiled with a cylindrical piece for rolling contact against the front side of the frame which abuts up to the joint, and with a protruding ring flange part which can be introduced into the jointing slot with a suitable depth therein by the said contact against the frame. It will be understood that in a very simple manner it is hereby possible to "roll" the jointing string into place in achieving a completely uniform, expedient mounting depth of the string, so that not only a good adhesion is ensured, but also a minimised consumption of jointing compound in the final jointing. The grip can hereby assume any angular position, and the user shall simply ensure that the implement is applied with sufficient pressure to establish contact with the frame in a single place, namely at the cylindrical contact part of the roller. The invention is illustrated in the drawing, in which fig. 1 is a perspective view of a basic embodiment of an implement according to the invention, figs. 2 and 3 are plane side views respectively of a second and a third embodiment of the implement, fig. 4 is a perspective view of a preferred embodiment of an implement according to the invention, and fig. 5 is a corresponding view for the illustration of the use of the implement .

In fig. 1 there is shown a plate-based implement 2 comprising a handgrip 4 which at its one end is split up into a curved contact part 6 which can be moved along with and in contact against the outer side 8 of a frame part, on the inside of which there appears a slot 10 out to the wall of a surrounding wall opening 12. At one side of the contact part 6 there is a longer, protruding narrow plate part 14 which, where as shown the handgrip 4 is in the inclined position, can be brought to protrude to a certain insertion depth inside the slot 10. When the implement is held and used in a more or less well-defined angular position in relation to the plane of the front of the frame 8, it will hereby be possible to effect a pressing-in of a jointing string 16 to a more or less uniform depth inside the slot 10.

With the embodiment shown in fig. 2, the contact part 6 is replaced by a longer slide-shoe 18 which serves to support the inwardly-penetrating plate tongue 14, and which is also connected with the handgrip 4 via a pivot connection 20. It will be understood that the desired penetration of the part 14 into the slot 10 can hereby be ensured regardless of the inclined position in which the handgrip 4 can be held.

This embodiment can be developed for the arrangement shown in fig. 3, whereby the slide-shoe 18 is replaced by a structure for the support of opposing rollers 24, which will ease the movement of the implement and spare the surface of the frame .

The preferred implement shown in fig. 4 and 5 has a handgrip 4 with an extension piece 26 which forms the bearing for an axle journal which, in a manner in which it can freely be turned, supports a roller 28 with an inner, cylindrical contact part 30 and an outer, narrower and longer-extending disk part 32.

In fig. 5 there is indicated the wall 34 of a building with an opening surface 36 in which a window frame 38 with a window 40 can be mounted. Between the surface 36 and the frame 38 there will normally be a slot 42 in which securing means and support means for the frame 38 are provided, but which outwardly must be closed by jointing with a smooth outer side at the front edge of the frame 38.

On this basis it is normal practice to introduce a jointing string 44 to a certain depth inside the slot 42, so that a free space is formed in front of the inserted string for filling out with jointing compound. As shown, the implement is used for precisely this insertion of the string, in that the user can simply hold the string up to the outer opening of the slot, and then with the cylinder part 30 in abutment against the side of the frame 38, and with the disk part 32 extending into the slot 42, the string can be "rolled" into the slot by movement of the implement. The string 44 will hereby be pressed in to the correct, uniform and moderate depth, merely providing that it is ensured that the cylinder piece 30 is held pressed in against the front of the frame 38. The insertion of the string can for obvious reasons not be driven further into the slot than to the expedient depth, which is determined by the radius of the disk part 32, and the user of the implement has no problem in constantly holding the cylinder part 30 in contact with the front of the frame 38, so that a suitable minimum depth of string insertion is also ensured all the way along the frame.

The implement will generally be able to be used for the pressing-back of relevant filling-out material, regardless of whether this consists of a string or of another material.

It shall be mentioned that two preferred embodiments of the roller head 28 in fig. 4 have the following dimensions:

1) roller part 32 : Diameter 58 mm, breadth 7 mm roller part 30: Diameter 38 mm,

2) roller part 32: Diameter 58 mm, breadth 4 mm roller part 30: Diameter 43 mm.
