Description

Hinge and locking body for a glazing system, especially in connection with balconies

The invention relates to a hinge and locking body for a glazing system, in accordance with the preamble to patent claim 1.

Background

When constructing new buildings and when renovating buildings, well-known glazing systems are installed in connection with balconies. These glazing systems are called, for example, balcony glazing. The systems typically comprise an upper profile and a lower profile, in which the necessary guide members are placed and where separate panes of glass are suspended between the aforementioned guide members. The profiles usually have a horizontal extent, and are attached to the structure of the building. With the help of the guide elements, it is possible to open and close separate panes of glass, preferably around a vertical axis of rotation, and they can also be pushed to the side along the profiles, whereby several panes of glass form a vertical stack, and the balcony is completely open. A known glazing system is shown in Finnish patent publication 84645.

The guide means comprise a hinge and locking body for each pane of glass, with which bodies the panes of glass that have been pushed aside and placed close to each other are locked together. The bodies are placed next to each other and are locked when the glass panes are turned and placed close to each other. The bodies are placed at a distance between each other when the panes of glass extend straight up, so that they form a continuous wall, whereby the distance between the bodies corresponds to the width of the panes of glass.

For hinge and locking bodies from prior art, problems sometimes arise in that the bodies break when the glass panes are opened or closed. The stress that causes the bodies to burst occurs especially when the bodies engage each other. Excessive use of force can also cause the bodies to burst. In locking, the purpose of a pivot bolt, which moves along the preceding body and is attached to the glass pane, is to rotate in the fork-shaped locking part of the subsequent body when the glass pane is turned.

Purpose

One purpose of the invention is to eliminate the aforementioned problems by proposing a new type of hinge and locking body. The hinge and locking body in accordance with the invention is as stated in patent claim 1.

The invention

With the help of the invention, it is possible to avoid situations where subsequent hinge and locking bodies are not placed next to each other, whereby, for example, the pivot bolt turns in the part of the locking body which is narrow and which is not intended for turning the pivot bolt. When a person moves the panes of glass close to each other, with the help of the invention it is possible to avoid situations where it seems as if the pane of glass is in its correct position because it no longer moves, but where the bodies are nevertheless not placed close to each other. If one also takes into account cases where the panes of glass are too far apart, he/she will use more force, and could destroy the bodies if they are placed next to each other in places where they are not meant to be next to each other.

By means of the projection and shoulder devices in accordance with the invention, the successive bodies are guided and centered in relation to each other. The positions of the bodies may be different when they are far apart and when they are moved towards each other, but the projection and shoulder devices adjust their relative position when placed close to each other. At the same time, it is possible to correct the unfavorable effect that the guide device has on the position of the body, whereby even the use of looser fittings is made possible, and whereby movement of the bodies is made easier.

Example

In the following, a preferred embodiment of the invention will be described in more detail, with reference to the drawings, where

Figure 1 shows a cross-section of a glazing system from prior art, where the glazing system is a glazing system for balconies; Figure 2 shows a perspective view of two hinge and locking bodies from known technology, which are placed one behind the other, with panes of glass suspended in them; Figure 3 shows a perspective view of a hinge and locking body in accordance with a preferred embodiment of the invention; Figure 4 shows the hinge and locking body in Figure 3, seen in the Y direction;

Figure 5 shows the hinge and locking body in Figure 3, seen in the Z direction.

In accordance with figure 1, an installed glazing system often comprises several subsequent panes of glass 1 which can be moved. The panes of glass usually have a rectangular shape, and are placed in the X and Y directions, whereby they stand in an upright position and form a closed wall when standing one after the other. They can be moved in the X direction, which is usually the horizontal direction. The glass panes 1 can be opened to a position where they extend in the Y and Z directions, which position is perpendicular to the closed position. In this position, the panes of glass 1 can be moved to the side in such a way that they stand close to each other and side by side, whereby they are stored on one side of an opening 3 to a building 2. The upper profile 4 and the lower profile 5 are placed parallel to the X direction, and each of these comprises necessary guide means 6 and 7, to which the panes of glass 1 are attached both above and below.

Figure 2 shows a hinge and locking body 8 from known technology in more detail, which hinge and locking body 8 belongs to the necessary guide members and is placed in particular in the upper profile 4. The body 8 comprises rollers 9, in which the glass panes 1 in Figure 1 are stored, and from which they hang down from the upper profile, as well as a pivot bolt 10 which is rotatably attached to the body 8 and via which the glass pane is attached to the body 8. There are also structures in which the rollers 9 can be horizontal or vertical. The pivot bolt 10 is attached to an element which is separate from the body 8 itself. The body 8 thus comprises the necessary fasteners, including for example the rollers 9 and the separate element, with the help of which the pivot bolt 10 is attached to the body 8, in such a way that the body 8 moves when the separate element and the glass pane move. The hinge and locking body 8 in the lower profile usually does not include rollers 9, and its position is upside down compared to Figure 2. The hinge and locking body 11 shown in Figure 3 is constructed in accordance with the above-mentioned principle. When the bodies 8 in Figure 2 move in the X direction, the pivot bolt 10 is parallel to the Y direction. The lateral direction, that is the Z direction, is normal to both the X and Y directions, whereby an orthogonal coordinate system is thus formed.

The body 8 has a rear end 82 which comprises fastening means 83 for fastening the pivot bolt 10, where the pivot bolt can also rotate in the fastening means, and at the same time be arranged in said guide means. The body 8 also has a front end 81 which comprises locking devices 84 for locking the pivot bolt 10 in a specific rotating position. The lockable pivot bolt 10 is attached to a corresponding preceding body. The bodies 8 are preferably identical, where the structure and dimensions are the same. The bodies 8 are often also symmetrical about a plane which coincides with the X and Y directions and which are placed on the center line of the element. The front end 81 and the rear end 82 each comprise an upper and a lower surface, which surfaces are in the plane of the X and Z directions.

The locking prevents deviations between the bodies 8 in the X direction. For locking, the bodies 8 are brought together, and the pivot bolt is placed in a locking slot 85. In a first rotational position A, the width of the pivot bolt 10 is smaller than in a second predetermined rotational position B. In position A, it can be moved in and out of the locking slot 85, but not in position B. The opening 86 to the locking slot 85 controls access in and out. The glass panes usually also have a molding or a profile 12, to which the pivot bolt 10 is attached by means of a slot 13.

Figure 3 shows a hinge and locking body 14 in accordance with an advantageous embodiment of the invention. The body 14 also has a rear end 142 comprising fastening means 143 for fastening the pivot bolt 10 (not shown). The fasteners 143 comprise at least one opening 146 which passes vertically through the rear end 142, and a recess 147 which surrounds the opening 146, where the recess is shown in Figure 5, and in Figure 3 is located below the rear end 142. The pivot rotates in the opening 146 and the collar in the pivot bolt is placed in the recess 147, whereby the body 14 can simultaneously hang supported in the pivot bolt, and whereby it is not necessary for the body 14 to slide up along the upper profile. The body 14 to be placed in the lower profile has a recess, the shape of which corresponds to the shape of the recess 147, but which is on top of the rear end 142.1 the lower and upper profile, the position of the body 14 is preferably similar. In the body 14 which is placed in the lower profile is

the opening 146 is preferably larger, while the locking slot is preferably slightly smaller.

The body 14 also has a front end 141 which comprises locking devices 144 with locking slots 144a, in which the pivot bolt is placed. The dimensions of the opening 144b of the locking groove 144a are adapted for the introduction of the pivot bolt in position A in Figure 2, but not position B. The front end 141 is located below the rear end of a preceding body, and the rear end 142 is located above it front end to the next body. Due to the step-shaped structure of the body 14, the front and rear ends of the other bodies are located on different sides of the body 14.

From Figures 3, 4 and 5 it appears that the locking devices 144 have the shape of a two-part fork, where on the inside of the ends of its branches 144c, 144d there are roundings 144e, 144f, for guiding the pivot bolt. The locking groove 144a is between the branches 144c, 144d, and on the outer edges of the ends of these there are inclined guide surfaces 144g, 144h, which guide the protrusions of the preceding body on different sides of the front end 141, whereby the front end 141 remains between these .

Figures 3, 4 and 5 further show that the body 14 has projecting elements 148 for centering the pivot bolt, where the projecting elements comprise two stick-like projections 148a and 148b, which are attached at a distance from each other to the rear end 142 and which extend backwards in the X direction. The devices 148 are placed laterally on both sides of the front end of the next similar adjacent body corresponding to the body 14. The body 14 has shoulder elements 149, for controlling the position, comprising two longitudinal shoulders 149a and 149b, which extend laterally and are attached to the side of the front end 141 along its entire length. The shoulder elements 149 also bring the front end 141 and the rear end of the preceding body closer together in the Y direction, and for this purpose they are provided with inclined guide surfaces 149c and 149d, which slope upwards towards the front end 141. The shoulder elements 149 have longitudinal (X direction) support surfaces 149e, 149f, and the projecting members 148 also have longitudinal support surfaces 148c and 148d. The support surfaces 149e and 148c of different bodies are placed adjacent to each other, whereby mutual movement of the front end 141 and the rear end of the previous body is prevented in the Y direction. The support surfaces 149e, 149f are positioned in such a way that the shoulder members 149 remain between the rear end of the preceding body and the projecting members of the preceding member. On both sides of the front end 141 there are also vertical sliding surfaces 150a and 150b, which extend in the Z direction. The projecting elements 148 also have vertical sliding surfaces 151a and 151b. The sliding surfaces 150a and 151b of different bodies are placed next to each other in such a way that the front end 141 remains between the sliding surfaces 151a and 151b.

For further guidance and to avoid collisions, the front edge of the front end also has inclined guide surfaces 145a and 145b, which on top of the front end 141 guide the rear edge to the rear end of the preceding body in the Y direction. The guide surfaces 145a, 145b slope downwards towards the front end 141. The guide surfaces 145a and 145b are simultaneously located at the ends of the branches 144c and 144d. Furthermore, the rear edge of the rear end 142 includes a rounding 152, which leads the leading edge of the front end to the next body below the rear end 142. The guide surfaces and the roundings cause the bodies to slide in the correct direction, even if the bodies collide with each other .

The invention is not limited to the advantageous embodiment above, but may vary in accordance with the patent claims.
