Description

Door or window hinge hardware swivel and tilt.

The invention relates to a hinge hardware according to the preamble of claim 1.

With document DE 7702766 U1 has been given to Know a hinge hardware of this type. In this hardware of hinge is provided, on the side of the frame, a corner bearing which forms a vertical axis and a horizontal axis for a leaf swivel / tilting To do this, a bearing pin that can turning around a horizontal axis intervenes with a first section cylindrical in a hole in the hinge body on the side of the blade. The first cylindrical section of the bearing pin is provided a shoulder that extends radially, serving as a stirrup for the hinge body on the side of the sheet and, in order to vertical adjustment of the blade, is assigned by means of a thread to the hinge pin. A second section of the hinge pin is Insert into a corner bearing bag and rest on a vertical wall of the bag.

The disadvantage in this case is the large hinge hardware dimensions, which requires a large space constructive. In addition, the hinge pin support on the wall vertical makes the hinge pin geometry complicated and therefore expensive.

With document EP 1074687 A2 it has been given to Know another hinge hardware. It is in this case a hinge arrangement for a rotating tilting window with a lower hinge body that is fixed to the frame and a body of top hinge that attaches to the movable blade, as well as a pin which acts respectively on the sections that form the point of Spinning axes support. The hinge body support point upper has a circular cross section for housing a corresponding section of the bearing pin. The pin it comprises a profiled section that is attached to the support point of so that it cannot rotate in relation to its axis, being able to move at an angle to it in a plane that contains the axis mentioned and perpendicular to the plane of the window. The pin it also comprises a centrally arranged circular ring, which serves as a stirrup and is between the profiled section and the cylindrical and slides on one end of the hinge body lower. The center of the axis of rotation of the tilt axis is It is at its other end.

From DE 2826945 C2 another known corner bearing for revolving swing doors or windows with a bearing support, in which a fixing element is screwed to the frame and whose rotating bearing element carries a hinge element on the side of the sheet, and in which there is a device for adjusting the hinge element on the side of the sheet, horizontally and parallel to the plane of the sheet, presenting the  bearing element the shape of a prism with cross section in the form of a regular polygon and the axis of symmetry of the prism aligned with the axis of rotation. The lateral surfaces of the prism are provided with a respective recess and these recesses are in a plane parallel to the plane of the window and at different distances from the axis of symmetry of the prism, being aligned with each other opposite recesses in which it is housed a tilting or turning pin. Fixing piece is configured here as a screw plate with two shanks of seat to fit in the frame, the bearing support being configured in two pieces. The rotating bearing element is provided with an internal thread and housed on an element of head that is configured as a threaded bolt and features a vertical opening The recesses are rectangular and the spike of tilt or turn is also configured with rectangular shape at the bottom, as well as provided with a safety boss and configured as a disk in the central part and shaped cylindrical at the top.

Document FR 1377934 A also follows a similar hinge hardware. The hinge hardware features a cylindrical pin that is coated with a plastic sleeve, at least up to the upper half, the sleeve being configured in the central part with a protruding ring that separates the body from lower hinge of upper hinge body.

Where in the practical use of hinge hardware the maximum effort occurs in the body of hinge, and with it in the support frame, having to resist this effort, as described above, the pin of bearing and hinge body, the effort, in the current state of the technique already known described above is between the ring or disc centrally arranged in the bearing pin and body bottom hinge. In the case of such a solicitation relatively large wear must be available and on the other hand this becomes visible after the request, for example when opening and close the window or door in the turn function or tilt due to waste produced by wear.

The present invention aims at perfect a simple design hinge hardware of the type mentioned at the beginning so that the sheet has, through the hinge hardware, a defined position of the pivot point with little wear

According to the invention, the objective is achieved. through the characteristics of the identification part of the claim 1. The dependent claims refer to other advantageous configurations of the invention.

The hinge hardware according to the invention has as an essential advantage that the bearing pin rests inside of the hinge body of the frame side, the pin being bearing assigned to a hinge body console by means of a protrusion that extends radially and supported in its lower end by a stirrup that defines the horizontal axis. Thanks to the advantageous bearing pin configuration, in the closing position and in the opening position by turning it It supports both the console and the stirrup.

According to the invention, the fact that in the housing is arranged a bushing that is fixed in said accommodation and that constitutes the stirrup and a lateral guide of the bearing pin contributes to a simple configuration, which Saves space and reduces wear. The cap, which therefore guides and supports the bearing pin, it is a component that is subjected to great effort in the hinge hardware. By consequently, there is the possibility of changing the bushing, which can be removed together with the bearing pin by pulling it from the hinge body on the side of the frame. The easy change and the Two-piece variant - cap with side hinge body of the frame - they make manipulation easy if necessary change and on the other hand make the latter economic, since that the hinge body on the side of the frame can remain in the mounting status and no need to change it.

Thanks to the cap resting on the console and the bearing pin acts on the bushing with a collar, the bearing pin does not act directly here either on the hinge body on the side of the frame, since between the hinge body console and bearing pin is arranged the bushing and the possible influencing factors caused by the effort produced by the weight of the sheet or at actuated from the leaf are transmitted to the bushing.

Another advantageous improvement foresees that the bushing is adapted in its cross section to the housing and the guide adopting an asymmetrical position along the axis horizontal. With the possibility of changing the cap is achieved by same time the lateral adjustment of the hinge hardware by means of a large number of different variants of bushings that, starting of the horizontal axis of the housing, may have positions asymmetric guide, different from each other. According to that, naturally it is also possible that the bushing can form a symmetrical position of the guide along the horizontal axis of the accommodation, if it is useful for the window in terms of position of the sheet with respect to the frame.

A particularly advantageous configuration provides for the second section of the bearing pin to extend inclined with respect to the first section. Through the separation formed by a highlight, the sections are arranged, starting from the highlight, mutually displaced. Therefore, accommodation in the hinge body on the side of the frame becomes smaller, since the tilt angle of the second section of the bearing pin is anticipated by the inclination, so that the ironwork of hinge must not be set too large.

In this way, the hinge hardware becomes more Economical and simple from a manufacturing point of view.

In different function positions of switching of the closing position and the turning position, the weight of the window leaf on the shoulder of the bearing pin is transmits exclusively to the socket or console as soon as the first section of the bearing pin is in position vertical.

A particularly advantageous improvement In this embodiment, it provides that the console is placed centrally in the housing with respect to the vertical axis. Function of the insertion of the bushing in the hinge body on the side of the frame, the hinge hardware application can be achieved to right and left. The precondition for this is that the housing is a through hole and the hinge body is symmetrical configured in the transverse direction to the housing.

Another feature is that the highlight in shape Disc of the bearing pin narrows down the bottom in the direction of tipping. This has the advantage that, even in the direction of the tilting movement, the distance from the hinge body from the frame side to the pin bearing remains unchanged, in order to exclude the function of Support for this area.

According to a feature of the invention, it is advantageous that the stirrup is formed by a concave arch of the bearing pin and a convex arch of the bushing. The arc-shaped embodiment provides the bearing pin with respect to the bushing a relatively action surface large, which has positive effects on the applied solicitation through the bearing pin to the bushing, since friction is reduces with increasing surface area.

Another advantage is that the center of the arches of the bearing pin and bushing is at the same time the axis of rotation of the bearing pin, which means that the body of hinge on the side of the leaf frame performs the movement of tilt through this axis of rotation. Thanks to the center of the axis of rotation is outside the hinge hardware, the axis of hinge hardware turn can be assigned to the point of tilt / turn of the blade starting from the frame lace, not protruding the bottom edge of the edge hinge fitting lower leaf contour. Thus, the bottom edge of the hinge hardware can end almost flush with the edge lower leaf contour, which has no positive effects only in the window extension movement, but also in the visual aspect and transport, since there is no edge that stand out

It is particularly advantageous that the bushing has a connecting rib for the lateral guide, being the junction nerve adapted to the obliquely angled extension of the bearing pin on the internally oriented limiting edge towards the bearing pin. In this way, the junction nerve limits the position of the bearing pin in the positions of closing and turning, which also in this case can achieve a Possibility of pressure adjustment via bushing variants depending on the design of the junction nerve.

According to another feature of the invention, it is advantageous that the bearing pin and bushing are united in drag form. Both assembly and disassembly of bearing pin on or from the hinge body of the frame side they are made with the cap completely located in the body of frame side hinge. In this way it is possible to extract and change the bushing with relative ease by pulling the pin bearing.

Another feature is that between the arc of the bushing and the connecting rib of the bushing is arranged a step: the free end of the arch of the bearing pin. He step retains this position both in the turning movement and in the tilt movement as in the closed position.

It is particularly advantageous that over shoulder and the cylindrical section of the bearing pin is arranged a plastic cap that completely envelops them. He result of the use of the plastic cap is a minor coefficient of friction and a smooth turning movement, with a long shelf life and without the use of additional lubricants.

Therefore, this configuration is translated also in a longer life of the hinge body.

The description and the drawings follow other advantages of the invention. According to the invention, the characteristics mentioned above and those indicated below can be used in each case separately or in various arbitrary combinations. The embodiments shown and described must be understood for the purpose of describing the invention, and are shown:

- figure 1: a detailed perspective view, of the hinge hardware construction units,

- figure 2: the hinge hardware already mounted on the opening position by rotation, according to the cut indicated in the Figure 1,

- figure 3: the hinge hardware in one view as shown in figure 2, in the open position by tipping and

- Figure 4: on an enlarged scale, a cut to through the hinge body on the side of the frame, with a pin bearing according to figure 2 in the closed or opening.

In the following, the same components carry The same references.

In Figures 1 to 4 a frame side hinge hardware, by means of which a sheet swivel swingarm can rest on a door frame, window or similar. This hinge hardware consists of five parts: a hinge body on the side of the leaf frame 4, a plastic bushing 24, a bearing pin 1, a bushing 13 and a hinge body on the side of the frame 5. The hinge body on the side of the leaf frame 4 there is a drill at one end intern 25 in which, in the mounted position according to figures 2 and 3, the cylindrical section 3 of the bearing pin 1 is housed in Swivel shape with a plastic cap 24 superimposed. In the direction of its height, the bearing pin 1 is fixed to the body hinge on the side of the leaf frame 4 by means of a shoulder 9, which is arranged in the center of the bearing pin 1 and also It is wrapped by plastic bush 24. In the drive in the opening position by turning and in the closing position, the plastic bushing 24 is subject to request essential between the shoulder 9 and the hinge body on the side of the sheet frame 4 and between the cylindrical section 3 of the pin bearing 1 and the hole 25 of the frame side hinge body of leaf 4. In the rotational opening position according to figure 2, axis 2 and a central axis of cylindrical section 3 extend vertically Starting from the vertical axis 2 of the cylindrical section 3 of the bearing pin 1, which is arranged on one of the ends of shoulder 9, section 7 extends from the other end of shoulder 9, displaced to some extent with respect to axis 2, in angled shape, that is, inclined with respect to the first section 3, in direction to the vertical axis 2. As can be seen in figure 2 and in Figure 4, a first limiting edge 27 of section 7, inclined with respect to the vertical axis 2, in the shoulder 9. The edge opposite limiter 23 of section 7, which is oriented towards the framework, however, presents a section 28 that extends parallel to the vertical axis 2, but a short distance from the shoulder 9 is transforms into a section 29 that extends parallel to the first edge limiter 27. In this way, a step 30 is created in section 7 which, in the opening position by rotation, it extends horizontally. This step 30 serves as the seat of the bearing pin 1 for the sheet of a window in a console 10 of the hinge body of the side of the frame 5. The console 10 is centrally arranged inside of the hinge body on the side of the frame 5, in order to ensure an applicability of the hinge body 5 right and left, as shown in figures 2 and 4. in figure 2 and figure 4 it can also be seen that the bushing 13 is arranged with a collar 15 between section 28, next to the step of bearing pin 1, and the hinge body console 10 on the side of the frame 5. In the closing, turning and tilting positions, bushing 13 is supports by means of collar 15 on console 10 as a seat, using the bearing pin 1 the console 10 as a seat only in the closing and turning positions. To end 11 of section 7 of bearing pin 1, section 7 is guided laterally by the bushing 13 by means of a guide 14. The bushing 13 presents also a junction nerve 22 which, between collar 15 and arch 19, reinforces the support between the two guides 14. It also distinguishes because it limits the angle of rotation of the bearing pin 1 in the closing and turning positions.

The possibility of changing the bushing 13 allows to use different variants of bushings that are distinguished by the position of the horizontal axis 17. This is achieved by giving the housing 8 an asymmetrical position by means of different thickness dimensions of the guide 14. At the same time, changing the thickness of junction nerve 22 at inclined limiting edge 23 lateral and pressure adjustment can be made. The already mentioned stirrup 12, which is located at the end 11 of the pin bearing 1, consists of an arc 19 in the bearing pin 1 and an arch 20, shaped complementary thereto, in the sleeve 13. To achieve the largest possible support surface in the area of stirrup 12 of the bearing pin 1 is provided in the pin bearing 1, as can be seen in figure 2 and figure 4, a step 26 that departs from the vertical axis 2, whereby the arc 19 it reaches approximately a quarter of a complete circle. Center 21 of the arches 19, 20 is arranged on the horizontal axis 6 and is It is outside the hinge hardware. In the closing positions and turn, the step 26 of the arc 19 is disposed between the rib of junction 22 and arc 20 of bushing 13 in a drag connection of shape, according to figure 2 and figure 4. In this position of switching is provided as a seat for the bearing pin 1 the shoulder 9 arranged through section 28 on the console and at the same time the arc 19 over the arc 20 of the stirrup 12. In the tilting position according to figure 3, the seat lo constitutes the arc 19 of the bearing pin 1 with the arc 20 of the bush 13. In the tilting position, the limiting edge 27 opposite the limiting edge 23, which is designed as the side length of section 7, rests with its entire surface on the hinge body on the side of the frame and thereby limits the angle of tipping
