Abstract

The invention relates to an extension piece (3; 4; 8) for a slide track (1) equipped with a slide groove (6). According to prior art, the ends of the slide tracks are interconnected at the angle point or a T-branch point by sheer joints. Owing to torsion of the tracks, the sheer joint becomes uneven and asymmetrical, in which case the slide casters of a balcony glass pane or the like cannot move flawlessly. By using an extension piece according to the invention, slide track angle joints, T-branch joints and ordinary extension joints are easily produced. The extension piece has a slide groove (6) and the coupling of the extension piece to the slide track is carried out by means of a connection piece (5) or connection pieces to be pushed into a space or spaces in the extension piece and/or the slide track so that the combined slide groove will form a smooth groove for the slide piece.

Description

Extension piece for a slide track
The present application has been divided out from Finnish Pat¬ ent Application 891724, filed on April 11, 1989.
The invention relates to an extension piece for a slide track, equipped with a slide groove. Slide tracks are used, for ex¬ ample, for purposes of securing and moving balcony glass panes, movable wall panels, and the like. On the upper or low¬ er edge of a balcony glass pane or the like there are secured slide pieces, usually slide casters, which slide in the slide groove of an upper track secured to the ceiling, or respec¬ tively in the slide groove of a lower track secured to the balcony balustrade or the floor.
Slide-groove tracks are in general supplied in full wall lengths, since unevenness is easily produced at the extension joints, in which case it is difficult to make the slide sur¬ faces form a smooth slide surface. Thermal expansion and in¬ stalling already produce torsion in the tracks to the extent that the slide surfaces of the two tracks will not remain on the same level. The travel of the slide rolls over the joints is thereby complicated. Delivering to the building site a full-length track having the length of a balcony or a room space is difficult, since it is too large to be carried to the various floors via the stairwell. Therefore the tracks are of¬ ten lifted to the balcony via outside, using a rope. The lift¬ ing, however, tends to produce torsion in the track, whereupon it will no longer function flawlessly. Sheer joints at angle points will also cause problems similar to those caused by the extension joints described above.
The object of the present invention is to eliminate the prob¬ lems described above and to provide an extension piece for slide tracks, in which the extension points will no longer cause problems.
The invention is characterized in what is disclosed in the characterization clause of Claim 1.
The extension piece according to the invention has a slide groove, and the interconnecting of the extension piece and the slide track is carried out using a connection piece or connec¬ tion pieces to be pushed into the groove or respectively grooves in the extension piece and/or the slide track. The ex¬ tension piece and the slide track are aligned end-to-end with one another, and the connection pieces are fitted into spaces mating with them so that the slide groove will continue as a smooth groove from the slide track over the extension piece.
According to a preferred embodiment of the invention, the spaces mating with the connection pieces in the extension piece and/or the slide track are profiled grooves. Most pref¬ erably the profiled grooves are located in the walls of the slide tracks and open outward.
According to another preferred embodiment of the invention, the connection pieces are integral with the extension pieces, in which case the extension piece and the slide track are placed end-to-end so that the connection pieces will push into the said spaces in the slide track. The connection pieces are preferably male pieces which are parallel to the slide track and protrude from the walls of the extension piece and which mate with the profiled grooves running in the walls of the slide track. The connection pieces are most preferably male pieces protruding from both end surfaces of the extension piece, two at each end.
According another preferred embodiment, the connection pieces are separate pieces to be pushed into grooves, parallel to the slide track, in the slide track and the extension piece. Ac- cording this embodiment, the connection pieces are first fitted into the said grooves in one piece, for example the extension piece, whereafter the pieces are placed end-to-end and the connection pieces are moved in their profiled grooves so that the joint between the pieces comes approximately at the half-way point of the connection pieces.
According to another preferred embodiment, the end surfaces of the extension piece and the slide track coming against each other are at a right angle to the longitudinal direction of the slide track. In this case, detrimental deformations due to thermal expansion are eliminated in the most effective way over the entire structure.
According to another preferred embodiment the extension piece is of a hard plastic or of aluminum. The slide track is in general of aluminum. The outer dimensions of the extension piece can advantageously be made greater than the outer dimen¬ sions of the slide track, whereby a sturdy joint is obtained. As regards the dimensions, it is essential that the slide groove will continue smooth from the slide track to the exten¬ sion piece so that the slide casters can move in them without hindrance.
According to another preferred embodiment the extension piece is straight or of a branched type, for example a T-shaped branched piece, or a branched piece bent into an angle, such as an angle of 90°, 45° or 135°. A rectangular extension piece is a suitable angle piece, which is needed in balcony glaz¬ ings. In branched-type extension pieces the branching point has preferably a protuberance which promotes the transfer of the slide caster to the branched track.
The extension piece according to the invention thus enables slide tracks to be extended and an angle point or a branching point be formed in them without coupling problems. It is a further advantage of the extension piece that, when tracks are selected for a certain balcony or other space, it is not necessary to observe millimeter or centimeter preci¬ sion; cutting to final dimensions may take place on the site, where coupling to an angle piece or a straight extension piece according to the invention can be carried out easily and with good results so that the slide groove will continue smooth, without any points which would hinder sliding.
The fact that the slide tracks can be cut into their final lengths on site substantially facilitates the storage and transportation of the tracks. Instead of it being necessary to store and transport long tracks which are vulnerable to dam¬ age, they can be stored and transported in shorter and stand¬ ard lengths.
The invention is described below with the aid of preferred embodiment examples, with reference to the accompanying draw¬ ings, in whiσh
Figure 1 depicts a perspective representation of extension pieces according to the invention, in a slide track arrange¬ ment.
Figure 2 depicts an illustrative diagram of part of a balcony upper track arrangement, which has extension pieces in the form of an angle piece and a branched piece, Figure 3 depicts a top view of a branched extension piece ac¬ cording to the invention, on a smaller scale, Figure 4 depicts a front elevation of the branched extension piece according to Figure 3,
Figure 5 depicts a top view of an angle extension piece, Figure 6 depicts a front elevation of the angle extension piece according to Figure 5,
Figure 7 depicts a top view of a straight extension piece ac¬ cording to the invention, and Figure 8 depicts a front elevation of the extension piece ac¬ cording to Figure 7.
The corresponding parts are indicated by the same reference numerals in all the figures. Figure 1 depicts a slide track arrangement in which some parts are presented exploded and other parts are presented coupled into the final form. To the slide track 1 shown in the middle of the figure there are cou¬ pled T-shaped extension pieces 4, from which there protrude connection pieces 5. The slide tracks to be coupled to the extension pieces, in one direction, are still separate from the extension pieces. Slide grooves 6 and profiled grooves 9 for the connection pieces 5 which are in the form of male pieces are visible in the end surfaces of the slide tracks 1. At the corners of the slide track arrangement there are angle extension pieces 3. The lower right-hand side corner of the figure shows a straight extension piece 8 separate from the slide track.
Figure 2 depicts part of Figure 1 in an enlarged top view. It shows the slide track 1 and the balcony glazing slide casters 2 which slide in the track. For the sake of example, casters 2 are shown in different positions, but they do not constitute a part of the invention. The track arrangement has an angle piece 3 according to the invention, the joints between the piece and the slide track being indicated by lines 3a and 3b, and additionally a branched piece 4 according to the inven¬ tion, its joint being indicated by lines 4a and 4b. With respect to the angle piece 3 and the branched piece 4 there are shown, with dashed lines," also the points of those joints which would be needed if the extension pieces according to the invention were not used. The sheer joint at the angle point is indicated by numeral 3c and the sheer joints of the branched piece by numeral 4c. Joints 3a, 3b and 4a and 4b are straight, smooth extension joints which do not hinder the movement of the casters 2 across the joints in the slide groove. The T-branch piece 4 according to Figures 3 and 4 has connec¬ tion pieces 5 which are integral with it. These connection pieces are located below the slide groove 6 of the extension piece and mate with profiled grooves 9 located at the cor¬ responding height in the slide track on both sides of it. Ref¬ erence numeral 7 indicates a protuberance at the branching point, promoting the engagement of the slide caster in the branch slide groove.
The angle piece according to Figures 5 and 6 has, as has the branched piece 3, connection pieces 5 which are integral with the angle piece. The angle piece 4 corresponds fully to the T- branch piece except that it has only two branches which form a right angle with each other, and not three as does the branched piece.
The extension piece 8 according to Figures 7 and 8 also has connection pieces 5 which are integral with the extension piece. The straight extension piece depicted here can be used anywhere within the length of a straight slide track. By means of this piece it is possible to couple a track of an arbitrary length to another track, which has been cut to a suitable length.
The cross-section of the extension piece may have greater outer dimensions than has the cross-section of the slide track. The slide track may in part or in total go inside the extension piece, thereby making a sturdy joint. What is essen¬ tial is only that the slide groove is left smooth, without any threshold points. In this case thermal expansion will not pro¬ duce stresses at the joint and the joint will not open.
It is clear to an expert in the art that the various embodi¬ ments of the invention may vary within the framework of the claims presented below.
