Provision of support.

Field of the Invention

The invention refers to an arrangement of support for balcony glazing or a mobile element similar, which consists of a first guide rail for two units of lift / wheel of the element, which are movable in the direction length of the guide rail and that carry substantially the weight of the element, and a second guide rail, against which it is left stand a guide means, protruding from the opposite edge with with respect to the support unit / wheel of the element, and, specifically, a support provision in which the element is arranged to move on a route, which includes the minus two first and respectively second guide rails located at an angle to each other.

Background of the invention.

In the previous methodology, shown in the Publication WO 99/32752, describes a solution in which the turn of the wheel assembly that takes the element to a corner is get by means of additional pieces placed in the corner of the guide lanes. The mentioned solution presents the following disadvantages:

-

How the angle between groups of elements, and therefore between guide rails, can be any, usually between 180 and 90 grades, additional pieces will always have to be made of separate form for the corner in question.

-

The fixing the small additional parts to the guide rail must be carried out in the installation phase at a site adequate and is therefore an expensive and unreliable process.

-

The friction between the additional part and the wheel could prevent the turning process, unless the parties in question are lubricated

-

When the wheel turns, you always have to "straighten it" in the area of conveyor lane and therefore can be left at least in part, "in the air".

Summary of the Invention

The objective of the invention is to eliminate disadvantages related to the known solution and provide a simple, easy-to-support lift arrangement Manufacturing and installation and safe.

The previous objective is achieved through a support provision, characterized in that first and respectively the second adjacent guide rails they form each other a miter joint, in which the unit of lift / wheel comprises a frame, which is held in the non-pivoting element, to which a wheel is connected to hold and transport the element, and in which the first guide rail It consists of a cavity, in which an axis type piece is placed included in the frame to move laterally in one way controlled, and on which there is at least one side a surface of wheel guide.

This solution is suitable for use when the first guide rail forms the bottom rail of the arrangement of  lift, where the units of lift / wheel of the element, and therefore the element integer, and the second guide rail forms the top lane of the support arrangement, against which the edge rests opposite with respect to the bearing unit / element wheel Only in the lateral direction. In this type of solution, the guide surface of the lift / wheel units can be done uniformly and flat, which means that the lift / wheel units have the guide surface Available in all positions.

Especially when the first guide rail forms the upper lane of the lift arrangement, where the bearing units / wheel of the element are attached and, therefore, the entire element, the vertical support of the lift / wheel units requires additional provision due to the cavity in the first guide rail to prevent the Element change position at its height. This arrangement additional is characterized in that on the outside of the type piece shaft in the frame there is a protruding part, whose bottom surface it is arranged to rest against said guide surface of the wheel on the first guide rail and / or one or more surfaces of separate guide, when the item is transported from the first guide rail, passing the connection point, to the next First guide rail.

Detailed description of the invention

Figures 1 and 2 show schematically An example of balcony glazing. The disposition of support of the glass elements (1) in this type of balcony glazing consists of a first guide rail (2) and a second guide rail (4). The first supports two units of lift / wheel (3) of the element, which are movable in the longitudinal direction of the guide rail and carry substantially the element weight (1). A guide means (5), which protrudes from the opposite edge with respect to the lift / wheel unit (3) of the element (1) is arranged to rest against the second rail guide (4).

In the examples shown in Figures 3, 3a and 3b, the first guide rail (2) is formed by the upper guide rail and the second guide rail (4) by the lower guide rail. At example shown in Figures 3c and 3d, on the contrary, the first guide rail (2) is the lower guide rail and the second guide rail (4) is the upper guide rail.

The support arrangement is intended also for cases in which the element (1) is available according to Figures 1 and 2 to move on a route that It comprises at least two guide rails (2) and (4) placed in a angle to each other.

Figure 4 shows that the first Adjacent guide rails (2) form a miter joint. The second guide rails (4) also form a miter joint each. In the example shown in Figure 4, the guide rails (2) are perpendicular, but it is evident that the angle between them It can be freely selected.

Figure 3 shows that the unit of lift / wheel (3) comprises a frame (7) connected in its lower end to the element (1), said frame being subject to element in a non-pivotal way. A frame is connected to the frame (7) wheel (8) to hold and transport the element (1). The wheel (8) it is connected by means of a horizontal axis (16) to the frame (7) and is arranged to rest against the guide surface (11), preferably horizontal, arranged in the guide rail (2).

The first guide rail (2) has a cavity (12), in which an axle type part (6) is provided, comprised in the frame (7), with an outer surface that is preferably a circular cylinder, to move laterally from a controlled way On the other side of the determined vertical plane through the cavity (12) there is a guide surface (11) for the wheel (8).

The frame (7) comprises a projecting part (9) on the outside of the shaft type part (6), whose surface lower (20) is arranged to rest against the mentioned guide surface (11) of the wheel (8) in the first guide rail (2), when the element (1) is transported from a guide rail (2), passing the connection point (17) to the next guide rail (2). In addition or instead, the lower surface (20) may stand against one or more separate guide surfaces; at example shown in Figure 3 against the guide surface (21) and in the examples shown in Figures 3a and 3b against the guide surface or guide surfaces (22).

In Figures 3 and 5 it can be seen that the lower surface (20) of the frame (7) is sized so that when the element (1) is parallel to the guide rails (2) and (4), the lower surface ( 20) is in the cavity (12) of the guide rail (2) and, therefore, is separated from the guide surfaces (11) and (21). The support unit / wheel (3) of the element (1) is sized so that it will have space to rotate inside the first guide rail (2), when transporting the element (1) from one guide rail to another, passing the connection point (17). In addition, as the clamping surface of the wheel (8) placed against the guide surface (11) of the wheel (8), and said lower surface (20) of the frame (7) are basically placed in the same plane, when the element (1) is transported from one guide rail to another, the frame (7) can rest on its lower surface (20) against the guide surfaces (11) and (21), when the wheel (8) loses grip on the guide surface (11) in the corner between two guide rails
successive (2).

The wheel clamping surface (8) placed against the guide surface (11) of the wheel (8) and the mentioned lower surface (20) of the frame (7) can also be arranged on a basically common conical surface (not shown) with the shaft type part (6).

In Figures 3a and 6, the projecting part (9) and the lower surface (20) on it are arranged above the wheel (8), which means that an area of additional guide (22) in the guide rail above the wheel (8). A corresponding guide surface can also be arranged also on the opposite side of the guide rail (2), as shown in dashed line.

Figures 3b and 7 show another example in the that the projecting part (9) is comprised of a shaped piece of / wheel type, which is fixedly fixed in the frame (7), or that is mounted on it alternately on a rotating basis by bearings, the bottom surface (20) of the piece to rest against the guide surface or surfaces marked by reference numbers (22) when the element (1) is transported from one guide rail to another.

Regardless of the solutions shown in the other Figures, in Figures 3c and 3d the lower guide rail (2) hold the support units / wheel (3) of the element (1), while the upper lane (4) only guides in the direction side.

In Figures 3c and 3d, the unit of lift / wheel (3) comprises a frame (7) connected in its upper end to the element (1) and non-pivotally fastened in the element (1). A wheel (8) is connected to the frame (7) to hold and transport the element (1). The wheel (8) is connected by middle of a horizontal axis (16) to the frame (7) and is arranged to stand against the guide surface (11) forming the surface inside lower horizontal guide rail (2).

In the case shown in Figure 3d, the mentioned guide surface (11) has a uniform level, while in the example shown in Figure 3c there is a gap (24) in the center of the surface (11).

Corresponding to the example shown in the Figures 3 and 5, in Figure 3c, the bottom surface (20) of the protruding part (9) of the frame (7) is sized in such a way that when the element (1) is parallel with the guide rails (2) and (4), the bottom surface (20) is in the cavity (24) of the rail guide (2) and therefore separated from the guide surface (11). When the element (1) is transported from one guide rail to another, said lower surface (20) rests against the surface guide (11) and therefore prevents the wheel (8) and, at the same time, the entire element (1), change position in its height.

In the case shown in Figure 3d, the guide surface (11) is uniform and therefore the wheel (8) it has continuous support of the guide surface (11), which means that the additional support provided by the surface Bottom (20) of the frame (7) is unnecessary. In this case, the frame (7) does not need to have the projecting part (9) used in other embodiments of the invention, whereby the design of the frame can also be freely selected in this respect.

The support provision of this invention works as follows:

In Figure 4, the units of lift / wheel (3) of the element (1) are shown in four different positions I-IV, when the element is move past the connection point (17) of the guide rails (2).

In position I, both lift / wheel units (3) of the element (1) are in the straight area of the rail
guide (2).

In position II, the left unit (3) is in a corner between two guide rails (2) and is pushed in part to  another guide rail, in which case the mentioned unit (3) is no longer held on the wheel (8), but on the guide surfaces (11) and (21) through the parts (23) marked in black on the surface bottom (20) of the projecting part (9) of the frame (7).

In positions III and IV, both units (3) are fastened on the guide surfaces (11) and (21) through the black marked parts of the bottom surface (20) of the protruding part (9) of the frame (7).

In the next phase (not shown), the element (1) is again parallel with the guide rail (2) and subject only by the wheels (8) on the guide surface (11).

When the element (1) moves in the direction of the guide rail (2), only the wheels (8) hold the element (1). On the other hand, when the element (1) is transported passing the corner between two guide rails, the element holder (1) is changes partially or completely on the bottom surface (20) of the protruding part (9) of the frame (7).
