The invention relates to the loop for rotary connection sash frame, in particular the door with the door frame containing joined with frame chassis and connected with a wing swivel bracket, which is based on the chassis.

This loop is known from EP 1 400 646 B1. It is used for flush mounting in the space of a fold combinations profile frame and sash. Thus, it is not visible from the outside, which improves the appearance combination of frame and casement compared with conventional loops and provides protection loops from exposure to the outside when the sash is closed. Thus, such secretly located loops are characterized by improved protection from hacking, compared with visible from outside loops.

To ensure the possibility of using secretly installed loops also in the so-called overlapping the systems in which the frame profiles and/or leaves have the tabs that when the sash is closed partially overlap outside corresponding to a different profile, the rotary axis is installed with the possibility of displacement in the body element of a frame by turning along stipulated in lying opposite to each other walls with the guiding surfaces of the guide tracks. This leads to the fact that the shutter at the turn not only rotates around the rotary axis, but also moves outside the space of a fold. The clash providing overlapping system of tabs with the corresponding another profile prevented in many combinations profiles.

In the known of the EP 1400646 B1 loop directing tracks are covers of the case, which svininy with the rest of the body. They serve for placing of slide elements, which in turn relies rotary axis.

The disadvantage of this loop is that a substantial part of the forces holding and management should be allocated in the frame through the guide track. Therefore, on the one hand, to comply with the cover is quite stable. On the other hand, should be provided with accurate landing after screwing that, in practice, require installation of pins between the cover and the housing. In addition, the loop because of the large number of structural elements is difficult to build, requiring high costs of labour in the manufacture because of the need to provide moving rotary axes of teeth on the housing and swivel the bracket.

In the US 2767425 disclosed loop containing the guide slot, which is made between one of the sliding surfaces, formed by the swivel bracket, and concentric surface of the guide plate. This guide plate svinina with screw swivel bracket. Guide the surface and guide plate is clamped guide, since guide plate clamped load elastic force of the sending member. For heavy doors or large current loads this loop is unsuitable, because the guide plate at overcoming elastic force is separated, and consequently, swivel bracket can develop uncontrolled clearance.

That is why the basis of the invention is to create a loop for hidden installation, which is characterized by the simplicity of the Assembly of its structural elements and their high load-carrying capacity. In addition, the loop should be relatively cheap to manufacture.

This task is solved with the use described in paragraph 1 of the claims of the loop. Due to the fact that swivel bracket contains the guide slot with concentric directing surfaces, and the body contains the guide element that sent the guiding surfaces, so it is possible to move swivel bracket relative to the body along a specified guide slot trajectory, swivel bracket turning describes a given curvature of the guide slots curve of the path, so fold when opening receives motion component, which removes apart facing each other in the closed state, forming a zone of a fold the sides of the leaf and the frame. Thus, the loop, according to the invention, suitable for overlapping systems. Based on the direction of the guide slot guide of the phone to transmit forces on the surface between swivel shackle and body, so the loop is also suitable for heavy loads. As swivel axis swivel bracket is fixed, it doesn't require complex gearing or separate mounting the slide elements that affect labour costs associated with the manufacture of hinges, according to the invention.

Big permissible load is achieved also due to the fact that swivel bracket according to the invention, contains about having the form of a quarter of a rod constructive element, which is fixed with a few distant from each other in the longitudinal direction screws, penetrating guide in the elongated hole. The implementation of structural element having approximately the form of a quarter of a rod, on the one hand, provides high stability as a constructive element can be done without massive loss of the maximum possible angle of aperture. On the other hand, a few screws along the element loops that lead to sufficient direction hinge bracket, make possible the lock without the use of this high current loads.

Loop which is also suitable for flush mounting, known from EP 887501 B1. In this loop swivel bracket is bent in the form of an arc of a circle and is having the shape of an arc of a circle notch in the retaining part. While performing decreases with the increase of the angle of aperture surface, which is passed through force between the sash and frame. This is a significant disadvantage, in particular, because just opening the shutter should expect the highest forces.

In a preferred embodiment of the loop, according to the invention, the guiding surfaces formed facing each other by the parties selectively designed to bond with each other or partial structural elements rotary clamps. On the basis of this can be especially easy to collect loop, according to the invention, by the fact that, while separated structural elements, first ensure adherence one structural element to guide, and then fix the other structural element.

Mounting can be done especially preferably with screws.

If the screws penetrate, which is especially preferably guide in passing in the direction of movement, having elongated shape of the openings, that effectively prevents a full rotation of the guide slots for a guide that would lead to the separation of the swivel bracket from the chassis.

Therefore, elongated holes preferably may be of such dimensions and can be arranged so that their ends limit the navigation path, on which swivel bracket can move relative to the housing. In other words, on the basis of the size of the oblong holes you can limit the maximum angle of aperture leaves up to the desired value. So there is no need for installation of stoppers doors that spoil the appearance and pose a risk of tripping.

To prevent jamming and to reduce wear loops, according to the invention, the guiding surfaces preferably equipped with a liner from reducing the friction material. The liner can be a separate component. However, it is also possible to create liner due to firmly put on the guiding surfaces of the layer or chemical or physical processing of sliding surfaces.

Hinge bracket can be performed divided parallel to the hinge axis and contain with a guide slot guide part and have a shoulder for fastening the leaf) fixing part. On this basis it is possible even when not connected together a guide and fastening parts of the first pre-mounted be fixed on the frame, on the one hand, and on the sash on the other hand, constructive groups loop, and then set the loop on the frame due to the installation guide and mounting parts on each other.

In one particularly preferred modifications made separated hinge bracket it additionally contains a device that provides moving guide and mounting parts relative to each other in parallel to the hinge axis and fixing these two parts in the desired position. Adjustment of the leaf in the frame parallel to the hinge axis, also called the vertical alignment possible in this case a simple way.

To facilitate connection of the guide and mounting parts with pre-mounted structural elements, especially preferred modification at least at one end of the parties to the hinge bracket provided by excavation, which can engage in a certain position opening hinged bracket located on the body can move the locking element. Based on this, you can fix the guide part during the process of installation of the valve in a predetermined position opening, so during this process, there is no need to hold it manually. Due to this decrease also a risk for injury during the installation of doors, for example, by clamping finger between the body and the hinge bracket.

To provide an easy-align perpendicular to the hinge axis, also called horizontal alignment between the shoulder and the mounting part may provide counterforce. In this case, the horizontal alignment can be done by changing the number of struts or through the use of spacers different thickness. This spacers can be preferably made of heat-insulating material to prevent excessive cold bridges.

Based on directions provided on the casing of the sending of the item on the guiding surfaces provided on an angle bracket guide slots already provided direction with a small gap hinge bracket in the chassis. However, for ease of Assembly loops, according to the invention, and additional improvements of the guide functions in one preferred embodiment of the loop, according to the invention, the casing contains at least one passing concentric guide slots Cam track, which includes ensuring directions connected with a swivel hinge guide. Based on this, eventually the changes of mechanical purpose hinge bracket already positioned in the housing before connecting together forming the guiding surfaces of structural elements rotary clamps. This prevents difficult to hold the chassis and swivel bracket at connection together. In addition, due to the additional directions when opening and closing the shutters reduced the clearance between the rotating shackle and body, due to which the leaf can be performed with a smaller gap relative to the frame.

Especially it is preferable to provide in case two rails of the track on lying opposite to each other the parties, with each rail track is part of the tab, because on the basis of this loop, according to the invention can be used equally for opening the left and right wings, and you can further reduce the gap between the swivel shackle and body.

To enable input on the surface forces in the guide track to reduce load the tabs preferably be in the form of an arc of a circle.

To reduce wear guides tracks and/or tabs may contain inserts of reducing the friction material.

In particularly preferred embodiment of swivel bracket is made essentially of a U-shaped, with one free U shoulder forms a party fit for a sash, and on another free shoulder formed one of the guiding surfaces. This guide the surface may be made in the first separate, then United with swivel bracket constructive element, or in the very swivel the bracket.

Indicated in figure 1-4 in General position 100 is the first example of execution of the loop, according to the invention, contains a body 1, which is made about the form of baths and has the shape of a rectangular parallelepiped. On the narrow sides of the housing 1 2 formed in favour of the outer loop 3 console, which each have two holes 4 for passing mounting screws 5.

Shown in figure 1 on the left of the longitudinal side of the hull formed a guiding element 6, which has a cross-section the form of a cut in half lengthwise cylindrical pipe. Guide 6 contains three located on distance from each other in the longitudinal direction L with elongated holes 7.

On both ends, which guide 6 stuck on one of the narrow parties 2, i.e. the top and bottom in figure 1, the guide item 6 surrounded made concentric him guide track 8, which is made open to the internal space of the 9 case 1.

In addition, the loop contains 100 swivel bracket 10, which is about the U-shaped cross section. Shown in figure 1-free-shoulder 11 contains two 12 holes for passage of the corresponding attachment screws 13, which secures 11 on the shoulder sash F (see figure 2).

In addition, swivel bracket 10 contains about having the form of a quarter of a rod constructive element of 18, the convex side 19 of which has a radius of curvature, which corresponds approximately to the radius of curvature of a concave side 20 guide item 6. On the concave side of 20 there are three located on distance from each other in the direction of the longitudinal axis L liner 21 of which decrease friction material, which reduces the friction between constructive element 18 and convex side 20 guide item 6.

As shown in figure 1, on the shoulder 14 swivel bracket 10 above and below the generated form the continuation of the guide surfaces 15 in the direction of the longitudinal axis L ledges 22, which are made in the form of an arc of a circle so that they form with the guide tracks 8, which in turn provided reduce the friction of sliding inserts 23, landing slip.

A constructive element of 18 Svinin with shoulder 14 with three screws 24 that contain each spacer 25. The screws 24 permeate shoulders 14 in the hole 26 and guide 6 in one of the elongated holes 7. The screws 24 are screwed into the appropriate screw holes 28 constructive element of 18, while they pierce the ear 21 in elongated holes 29 and liner 17 in the hole 30. Struts 25 are of such dimensions that they end approximately flush with the concave side of the liner 30.

The convex side of the 19th constructive element 18 forms a guide surface 31, which forms, together with the track surface 15 shoulder 14 guide slot, 32, which interacts with slip guide item 6 (see, in particular, figure 3 and 4).

In line with this, in assembled condition loops 100 guide 15 surface interacts with slip with the convex side 16, rail surface 31 - with the concave side of the 20 guiding element. At the same time the tabs 22 also with possibility of sliding part of the guide track 8, so swivel bracket 10 accurately directed on building 1. Because the screws 24 pass through the elongated holes 7, that their ends can form stops 27, which limit the maximum angle of aperture swivel bracket 10 and thereby sash F relative to the housing 1 and thus relatively frame R. Rotating swivel bracket 10 is happening around rotary axis's, which is located inside the frame R about the side edges of building 1.

Shown in figure 5-9, indicated in General position 200 loop, according to the second variant of execution of the invention, contains case 101, which is also made about the form of baths and has the shape of a rectangular parallelepiped. On its narrow sides 102 formed in favour of the outer contour console 103, which each have two holes 104 for the passage of the corresponding attachment screws 105. In addition, each console 103 near edge vinobrani part 101' corps 101 about the middle provided by another hole 104'through which if necessary can be screwed into the frame R another, not shown in the drawing mounting screw.

Shown in figure 5 on the right of the longitudinal side 101 formed a guiding element 106, which has a cross-section shape divided in half lengthwise cylindrical pipe. Guide 106 contains three located on distance from each other in the longitudinal direction L elongated holes 107.

The guide element is at the top and bottom up to the flat of the bounding surfaces 108.

In addition, the loop 200 contains a swivel bracket 110, which has a guide part 133 and mounting of 134.

On the guide part 133 formed concave guide the surface of 115, the curvature radius of which corresponds to the convex side 116 guide item 106. Guide the surface of 115 covered not shown in the drawing liner of reducing the friction material.

In addition, swivel bracket 110 contains about having the form of a quarter of a rod constructive element 118, the convex side 119 which has a radius of curvature, which corresponds to the radius of curvature of a concave sides 120 (see Fig). On the convex side 119 constructive element 118 performed at a distance from each other four liner 121 of which decrease friction material, which reduces the friction between constructive element 118 and concave side 120 guide item 106.

Constructive element 118 Svinin with three screws 124, which contain each spacer 125, with a guide 133 part. The screws 124 permeate constructive element 118 in the corresponding hole 126 and guide 106 - in one of the elongated holes 107. The screws 124 are screwed into the appropriate screw holes 128 guide part 133. The length of the spacer 125 only a little more material thickness guide element 106, and the diameter corresponds essentially to the width of stretched holes 107.

In line with this, in assembled condition loop 200 guide the surface of 115 interacts with slip with the convex side 119, rail surface 131 - with the concave side 120 guide item. Because the screws 124 pass through the elongated holes 107, that their ends can form stops 127, which limit the maximum angle of aperture swivel bracket 110 and thus sash F relative to the housing 101 and thus relatively frame R. Turn the rotary bracket 110 happening around rotary axis's, which is located inside the frame R about the side edges of the body 101.

On the front end as a constructive element 118 and guide part 133 caused liners about 135 round cross-section of reducing the friction material. They slip in the management loop 200 on relevant neighbouring restrictive surface 108.

As shown, in particular, figure 5, guide part contains 133 on its addressed to the mounting part 134 side two located at a distance from each other in the direction of the hinge axis projection 136, which have in their free ends of the areas of thickening 137 (see also 6 and 7). Mounting of the 134 supplied completed with the appropriate tabs 136 cross-section groove 138. She has turned to the guide part 133 side introductory hole 139, which takes place from the middle of approximately the same length to end the ends of the mounting part 134, and which is intended for introduction of one of the tabs 136 into the groove 138.

Connection flush between the guide 133 part and fixing part 134 is achieved by the fact that after the introduction of one of the tabs 136 in the hole 139 both parts are shifted relative to each other in parallel to the hinge axis, so that both tabs are engaged flush with groove 138.

To enable commit guide part 133 and fastening parts 134 engaged with each other, end zone 138 grooves have threaded holes, designed to screw into the screw spindles 140. Align parallel to the hinge axis (vertical alignment) can be done by unscrewing, respectively, screw-threaded spindles 140.

In addition, the loop contains 200 mounting part 141, the contour of which is agreed with the notch T in the sash. It contains a few holes 142, which are used for passing the mounting screws 143 for screwing with a wing F.

In addition, the Assembly part 141 provided by the screw holes 144, which are used for driving screws 145 order screwed mounting part 134 to the Assembly part 141.

Between the mounting part 134 and mounting part 141 provided spacer 146, which consists of the insulation material. To align the hinges perpendicular to the hinge axis (horizontal alignment) you can use the struts 146 in different number or different thickness.

The division swivel bracket 110 to guide part 133 and mounting of 134 has the advantage of being located on the side of the frame constructive group B1 and located on the side panels constructive group B2 can be pre-mounted on the frame and sash. In this case, to install shutters still only need to connect the rails and mounting parts 133, 134 loops as stated above.

So while this process was not necessary to keep manually guide 133 part in the open position, on the face parties of the guide part 133 made excavation 147, intended for insertion in turn screwed into the housing 101 fixing element 148 at a certain position opening. Fixing elements have on their opposite the observer side of figure 5 corresponding protrusion intended for introduction into engagement with two notches 149 on the housing 101. The ridges and grooves are located so that the tab on the retention guide part 133 position is one notch, and in liberating the guide part 133 position in another slot.
