Description

111021 Arrangement for turning point

The invention relates to an arrangement according to the preamble of claim 1.

t 5

The plate-like elements movable on the upper and lower guide rails are used as various space dividers. At least two parallel guide rails for the elements must be provided so as to achieve the desired closed wall on the one hand and to open the wall at least partially by pushing the elements aside. In this solution, however, the width of the exposed part of the wall is necessarily very limited.

Applicant's prior Finnish patent 81879 discloses a pivoting loft winding structure in which glass panes hanging on an overhead rail and supported in the transverse direction of the lower rail can be individually moved to the edge of the window-covered opening and turned there transversely to the rails, e.g. In this way, the screens are as if stacked against a wall, allowing the opening of the screens to be practically completely opened. In this known solution, the glass pane locks at its upper end from the point of its pivot axis to the rail above the pivot as soon as the pane is pivoted.

Such a solution is only intended for cases where the upper guide rail supports the glass panes and the lower guide keeps them in its direction. Such a solution is not suitable for use when the lower rail carries the movable element and the upper rail only keeps its direction .; I can get. A similar solution is also disclosed in EP-A-1085156.

U.S. Patent No. 89,532 discloses such an arrangement at the outset. The non-30 spot there is a stalling of the structure due to thermal expansion.

111021 2

It is an object of the invention to provide at the outset such an arrangement for providing a pivot point for the lower end 5 of movable plate-like elements, in particular terrace glazing elements or similar partition elements supported on the lower guide rail and supported on the upper guide rail.

This object is solved by the pivot arrangement according to the invention, the features of which are set forth in the characterizing part of claim 1.

ίο The guide piece may be tracked at the end of a lower guide rail, for example, adjacent to a wall. On the other hand, the guide piece may also be tracked between two rails of the lower guide rail, for example in the middle of a room to be divided.

The guide member is provided with a guide groove, at the bottom of which the body portion of the first lower steering member, or a part protruding therefrom, is arranged to rest. In particular, when the lower guide member rests on the lower guide rail, the lower guide member is supported by the guide member. By contrast, with the guide body, the guide portion of the lower steering member has no support function of any kind, but the support is provided through the body portion of the lower steering member, or through a portion which is separately projected therefrom.

The guide may be arranged to receive a first lower control member of one or more elements. In other words, one or more elements may be disposed adjacent the major surfaces of the guide piece 25.

♦

In a preferred embodiment of the invention, it is arranged that the guide member and the first lower guide member disposed thereon are provided with locking means for locking said pivot axis of the element at its lower end 30 when the element is pivoted.

3, 111021

In order to provide a lock between the guide member and the first lower guide member disposed thereon, in a preferred embodiment of the invention, the first lower guide member comprises a circular segment non-rotatable with respect to the element, with a straightly directed guide portion when the element moves on the guide rails, that one of the straight, parallel side surfaces facing each other of the guide piece is provided with a circular recess, and that the smallest diameter of the circular segment locking member is less than the distance between the straight side faces of maximum distance between opposing side surfaces at recess in circular shape. As such, however, it should be noted that the locking between the guide member and the lower guide member can be accomplished in many different ways, of which the above is only one preferred solution.

In a preferred embodiment of the invention, in order to remove the second lower guide member spaced from the first lower guide member in the simplest manner possible, the second guide member is arranged at a predetermined position next to the lower guide rail, or separately projecting therefrom, via a tracked portion, to raise the second lower guide member from the underside guide rail as the first lower guide member approaches its pivot point in the guide member.

Fig. 3 is a vertical sectional view in which the element to be moved by the upper and lower guide rails is entirely supported by said rails.

Fig. 4 is a sectional view taken along line IV-IV in Fig. 1, corresponding to Fig. 3.

Figure 5 is a sectional view taken along line V-V of Figure 1, corresponding to Figure 3.

In the drawings, there is shown schematically an arrangement for providing a pivot point 10 on the lower end of plate-like elements 4, in particular terrace glazing elements or the like, which are movable on the upper and lower guide rails 2,3.

The elements 4 include a first and second lower guide members 5, 6 arranged at the lower edge of the element. The lower guide members 5, 6, in turn, comprise a frame part 7 and a guide part generally supported by reference numeral 8 (FIG. 4) a lower groove having an open end having a pivotally mounted wheel 25 at its upper end, thus lower guiding members 5,6 surround the lower guide rail 3 on the top and two 25 sides.

The lower guide members 5, 6 are arranged to support the element 4 in its vertical direction while simultaneously guiding the element transversely to the lower guide rail 3. At the upper edge of the element 4 is provided a first upper guide element 9, 30 arranged to guide the element 4 transversely to the upper guide rail 2. If necessary, there may be more than one top guide member 9.

5, 111021

In order to allow the element 4 to pivot, a guide body 12 is provided extending the lower guide rail jonka 3, on which the first lower guide member 5 is arranged to move on its body 7 or a portion 5 (not shown) disposed thereon in the longitudinal direction. For example, a part disposed separately from the frame means a wheel (not shown), which may be necessary, in particular in connection with heavy elements 4, to reduce friction.

In particular, when the first lower guide member 5 rests on the lower guide rail 3, the lower guide member 5 is supported by the guide member 8 and the associated wheel 25 on the rail 3. By contrast, with the guide body 12, the guide portion 8 of the lower guide member 5 has no support function but is supported by said body portion 7 of the lower guide member 5 or by a portion separately disposed therefrom.

The guide piece 12 may be arranged at the end of the lower guide rail 3, as in the examples of Figures 1, 2A and 2B, or the guide piece 12 may be arranged between the two rails of the lower guide rail 3.

20

The guide body 12 has a guide groove 14 as best illustrated in Figures 4 and 2A and 2B. As the lower guide member 5 moves from the lower guide rail 3 to the guide piece 12, the body part 7 of the first lower guide member 5, or a part separately projecting therefrom, rests on the bottom 15 of the guide groove 14.

25

In the solution of Fig. 2A, the guide groove 14 is uniform throughout the length * of the guide piece 12. At the end of the guide piece 12 away from the lower guide rail 3 is provided a stop (not shown) for the lower guide member 5 which can be formed, for example, by a wall against which the elements 30 can be turned.

6 111021

In the solution of Fig. 2A, the frame member 7 of circular cross-section and slightly smaller in diameter than the guide groove 14 of the fence guide member is free to move even when the element 4 is pivoted transversely to the upper and lower guide rails 2,3. To ensure control of the element 4, the first upper control member 9 of the element 4 is then arranged to be locked when the element 4 is pivoted, whereby the pivot point 10 of the element 4 is formed at the pivot axis 11 formed by the garden guide element 5.

2A, the position of the pivot point 10 may vary slightly. Instead, in the solution of Fig. 2B, the lower guide member 5 locks into place in the guide piece 12 and thus the pivot point 10 is always at a precisely defined position.

In the following, the solution of Fig. 2B, in which the lower guide member 5 is arranged to lock into the guide piece 12, will be further examined.

In the example of Figures 1 and 2B, the pivot points 10 are at four positions (only the pivot points 10 provided for the lower control members 5 are shown). The element 4 is pivotable with respect to the pivot axis 11 formed by the first top guide member 20 at the top of the member and the first garden guide member 5 at the bottom of the member. Both of the guiding members 6,9 forming the pivot axis 11 are arranged to lock in position with respect to the longitudinal direction of the guide rails 2, 3 when the element 4 is pivoted relative to said pivot axis 11 at said pivot point 10.

25

The guide body 12 and the first lower guide member 5 positioned thereon are provided with suitable locking means 16,20 (a preferred embodiment of which will be discussed later) for locking said pivot axis 11 of the element 4 in its rotated position (Fig. 2B).

30 7 111021

In the example of Fig. 2B, the locking between the guide body 12 and the first guide member 5 located thereon is implemented such that the first guide member 5 comprises a locking member 16 having a circular cross-section which is non-rotatable with respect to the element 4. tin moves on the guide rails. Of the straight parallel side surfaces 18,19 facing each other of the guide piece 12, the other 19 is provided with circular recesses 20, one for each element 4. The smallest diameter dimension d of the y-ring segment-shaped locking member 16 is smaller than the distance a between the straight side faces 18,19 of the locking member 12. The maximum diameter D is substantially equal to the maximum distance A between opposing side faces of the locking member at the circular recess 20.

In the solution of Figures 1, 2A and 2B, the guide body 12 is arranged to receive four different elements 4, that is, it has spaces for four lower control elements 5 and thus spaces for four different elements 4. Of course, the number of elements 4 received by the guide body 12 can be selected to suit the particular situation.

20

Next to the lower guide rail 3 is an auxiliary guide 21 arranged in a predetermined position, as best illustrated in Figures 1,2A, 2B and 5. The auxiliary guide 21 is arranged via the body part 7 of the second lower guide member 6 or separately disposed therefrom to lift the second lower guide member 6 away from the guide rail 3 below (Fig. 5) as the first lower guide member 5 approaches its pivot point 10.

the arrangement for providing the pivot point 10 operates as follows.

Considering the cases shown in Figures 2A and 2B, each of the two lower left guide members 5 is in a position where the element 4 is 8111021 pivoted transversely to the lower guide rail 3. The lower right guide member 5 and the lower guide member 6 at the rail 3 belong to the same element 4, which in both Figs. 2A and 2B is pushed into its leftmost position parallel to the lower guide rail 3, with the lower guide member 6 4 can be moved in the direction of the arrow 22. In the case of Fig. 2B, the lower guide member 5 locks into place in the recess 20 of the guide piece 12 as soon as the element 4 is rotated about the pivot axis 11. In the case of Fig. 2A, the lower member 5 is completely unlocked, however, the locking upper control member 9 keeps the element 4 under control.

Finally, it should be emphasized that, unlike the example shown in the drawings, the lower guide rail 3 may also be trough-shaped, whereby the guide part 8 of the lower steering member 5,6 is formed by a wheel arranged to move within said train. The wheel width is slightly narrower than the inside width of the guide rail 3. In this case too, the pivot point 10 may be provided as an extension of the lower guide rail 3 to the tracked guide piece 12. The guide track 14 of the guide piece 12 may then be cross-sectional or rectangular by means of part 7 or control part 8 (wheel). The release of the lower guide member 6 from the lower guide rail 3 can then be arranged to take place through an opening provided in the side wall of the lower guide rail 3.
