Description

Upright mounting system with crossbars through a front link.

The patent refers to a system for joining profile bars used on facades (both uprights and crossbars, whether they are structural or semi-structural), band frames, walls mobile and in general in all cases where it is necessary join uprights with crossbars with miter joints, without work additional. A system of this class is known by the document BE-A-1003563.

There are a large number of systems to join uprights to crossbars by means of metal profile bars or plastic. The most advanced systems allow the union not sequential profile bars by frontal insertion of the crossbars in the uprights. This allows preparing crossbars before assembly, with the subsequent reduction of costs Costs are further reduced by the fact that this particular method allows a simpler assembly process in comparison with that of sequential joining systems.

Unfortunately, frontal joining systems known today, although they are effective they have costs of relatively high assembly and disassembly. In order to reduce these costs have devised numerous new solutions, with the objective of minimizing the preparation of the parts that are They have to unite.

Therefore we have passed the preparation of the uprights, creating notches where the  crossbars, to fit the same crossbars. These last, after they have been cut to the desired length, they are milled or shear in order to remove a part of its outer wall, next to the extremes. Then the crossbars are introduced frontally on lateral supports that have been fixed to the uprights by means of screws, and they are firmly fixed to these by additional screws. In addition, in order to favor the discharge of condensation water through the spillway of the upright, the ends of the crossbars are re-milled with the  in order to get two projections, one on each side, that directs the water to the channel mentioned above.

It is clear that the preparation costs of uprights and crossbars are very high, given the number of adjustments What needs to be done: double milling or shearing of crossbars, milling of the uprights; double punching uprights (in order to create the holes in which they are to be fix both the screws for the side supports and those they are required to join the crossbars to the uprights).

In addition, a certain amount of hand is required of work, both for the preparation of profile bars and for the previous fixing of the lateral uprights.

Other alternative front fixing methods include the use of joining elements that allow skipping part of the  Profile bar preparation process. According to these new methods, the crossbars are cut to the desired length. TO the ends are then closed with plastic caps that They act at the same time as joints and expansion compensators. Finally the crossbars and uprights are joined together by metal bars that are placed horizontally between the two and are fixed to them by means of screws. The metal bars are adjust in channels or special chambers of the crossbars, creating a typical cross joint in which screws are essential to keep the structure firmly attached. In addition to the low resistance to torsional stresses presented by crossbars, however it is necessary to drill or shear both the uprights such as crossbars, which makes the preparation of the various pieces, although to a lesser extent.

The objective of this invention is to offer users a profile bar joint system that does not require additional adjustments other than the cutting of the uprights and crossbars during the manufacture of facades, band frames and movable walls Consequently, this invention also has as aim to allow the front assembly and disassembly of the bars profile at extremely cost, thus offering great economic advantages

These and other objectives are achieved with the system as defined in the claims, which is the subject of this invention and which is characterized by the use of bars of profile, of a hairpiece and spacers.

The profile bars used for the manufacture of the crossbars are provided with at least one channel (whose longitudinal axis is parallel to that of the bars of profile), which develops vertically.

The profile bars used for the upright preparation are provided with at least two slots whose longitudinal axis is parallel to that of the bars of profile and that are symmetrical to the central brackets. In your section  transverse, each groove is provided with at least one jaw coupling, and a clamping jaw and an inclined plane. Each slot can be divided into two channels by means of a fin sufficiently flexible, whose longitudinal axis is parallel to that of amount, and that must be provided with at least one jaw of coupling and a clamping jaw. At the end of the at least a channel there is a projection that creates the inclined plane while At the end of the other channel a highlight creates a housing.

The hairpiece is provided with at least one bracket of perpendicular connection to the body. The body of each hairpiece is it houses at least one of the transom channels, while the end that carries the connection bracket protrudes inevitably of the same profile. The connection bracket can have a variable shape, but in all cases it must be provided at least one coupling jaw and a clamping jaw. The end of the connection bracket can be formed by a terminal, complete or not with the accommodation mentioned above. The insert can also be supplied with a guide bracket located perpendicular to the body of the hairpiece, and in it direction than the connection bracket. This guide bracket can be provided with a terminal, preferably located in its distal end and perpendicular to the bracket. The body of the hairpiece it can be subdivided into two or more sections that are parallel to the crossbars and that join in the upright. The hairpiece is provided with two or more holes, threaded or unthreaded, of the which at least one must be located in the same body of the hairpiece and the other near the connection bracket. In these holes are placed screws or fixed.

Once placed in the holes, the screws and fixed prevent the hairpiece from moving in a vertical direction. Do not However, in order to prevent heavy glass moons or panels or small loads cause a downward slide of the crossbar, you can use a metal spacer profile that have a diverse section structure.

The spacer, which can accommodate the gasket of vertical sealing and act as a support for the elements of retention of the elements of the shutter, is fixed to the upright by means of joints, seals and other fixing methods simple. It can have different forms, and it can be or not provided with a coupling jaw that is inserted in at minus one of the jaws of the stile. The spacer goes inserted into a specific slot for adjustment, or at least in one of the channels.

Each crossbar end may be closed. by a tight plug, formed by a body that has the same profile that the crossbar, from which stands a support that looks in opposite direction to the end of the crossbar. The support is provided of one or more grooves whose hole has the same dimensions as those of the body of the hairpiece, and may also be provided with horizontal holes

When using the hairpiece described above for fixing the crossbars to the uprights, all other adjustments except the cut of the crossbars. The crossbars are precut to the desired length in the workshop, and if it is precise cover their ends with the plugs in which they go Placed hairpieces. Consequently, the people in charge of assembly of facades, band frames, moving walls, etc., they will simply have to fix the hairpieces to the uprights and to the crossbars Therefore assembly is quick and easy, drastically reducing costs and the time that is usually required to carry out these operations.

A first example of realization of the system of union described here, especially suitable for facades continuous, foresees the use of insert 1 of a profile bar that will create the post 2, of a second profile bar that will create the crossbar 3 and spacer 4.

The hairpiece 1 is formed by a body 1.1 and a connection bracket 1.2, perpendicular to the body itself saying. Body 1.1 of insert 1 is divided into two parts that they are parallel to the crossbars 3, joined together near the corbel 1.2. The connection bracket 1.2 has a jaw of coupling 1.3 and a retention jaw 1.4. The hairpiece 1 is provided with four holes, two 1.5 threaded holes along of body 1.1, and two unthreaded holes 1.6, near the bracket connection 1.2.

The profile bars used to create the 3 crossbars have a drawer-shaped body 3.1, and two channels 3.2, whose longitudinal axes are parallel to those of the crossbars 3, developing vertically. The two parts of body 1.1 of insert 1 fit within channels 3.2, while the end provided with the connection bracket 1.2 protrudes from the channels 3.2.

The connection bracket 1.2 protrudes from the crossbar 3, since there is a predetermined stop point formed by the end of the channel that is created in the center of the two parts which constitute the body of the hairpiece 1.

The profile bars used to create the 2 uprights have a drawer-shaped 2.1 body and a double seat 2.2 whose longitudinal axis is parallel to that of the bars of profile and rigid edges. The central brackets 2.3 that hold the profile bar that blocks the glass or panel are located between the two seats 2.2. In the face that looks towards the brackets 2.3, each seat 2.2 is closed by a fin 2.4 whose axis longitudinal is parallel to that of the pillar 2. Fin 2.4 carries a coupling claw 2.5. In front of the claw 2.5 and on the edge of the seat 2.2 facing the outer side of the stud 2 is located a retention claw 2.6. At the bottom of each seat 2.2 there is a highlight that creates an inclined plane 2.7. The edge that looks towards the central brackets 2.3 of the seat 2.2 is also inclined, thus forming another inclined plane 2.8. A third Profile bar is used both as an internal clamping glass and as a spacer, 4. It is formed by body 4.1 which is provided with two brackets 4.2. Each bracket is provided with a coupling claw 4.3.

A sealed cap 5 closes the ends of each crossbar 3. Each plug 5 is formed by a 5.1 body that has the same profile as the tubular part of the crossbar 3, and a support 5.2 protruding from the same body 5.1. Cap 5 is crossed by two vertical slots 5.3, which have a light with them dimensions than the two parts of body 1.1 of insert 1, and by two horizontal holes 5.4, if required.

When assembling, the crossbar 3, already equipped with plugs 5 and hairpieces 1 at their ends, it frontally approaches the stud 2.

The hairpieces 1 are fixed to the crossbar 3 by middle of the fixed 7 that are inserted into the threaded holes 1.5  of body 1.1 of the same hairpiece. The fixed 7 are nailed in the walls of the same crossbar 3, preventing the insert 1 from being able to move on channels 3.2. Then the crossbar is carried frontally next to the post 2.

The connection bracket 1.2 of each insert 1 is adjust in each of the 2.2 seats until the claw of Coupling 1.3 engages with the claw coupling 2.5. The coupling claws 1.3 and 2.5 prevent the group formed by the crossbar 3 and insert 1 get rid of the amount 2.

In order to block the insert 1 and prevent that the group formed by insert 1 and crossbar 3 slide vertically along the stud 2, the 6 screws in holes 1.6 located next to the bracket connection 1.2. These screws, which can also pass through the holes 5.4 of the cap 5, mark the claw 2.6, creating grooves horizontals that prevent vertical sliding before mentioned. When the screws 6 are inserted in the seat 2.2, the pushes the connection bracket 1.2 of each insert 1 against its corresponding inclined plane 2.8. At the same time, the tips of the screws 6 use the inclined background 2.7 as a fulcrum to pry in cap 5, forcing it to press against the upright 2, thus preventing water leaks and so both ensuring a tight system. Two fixed 7 prevent the insert 1 moves within channels 3.2 of crossbar 3. The Fixed 7 are placed in threaded holes 1.5 of body 1.1 of insert 1, marking the walls of the crossbar 3.

The spacer 4, formed by a bar of glass support profile, prevents insert 1 from moving vertically when cross member 3 has to bear loads heavy or sudden.

Both brackets 4.2 are introduced in it seat 2.2 of the stud 2 in which the bracket 1.2 of the insert 1. Jaws 4.3 are coupled with the jaw of coupling 2.5 and retaining jaw 2.6 of seat 2.2, thus firmly fixing the spacer 4 to the post 2.

The spacer 4 is placed between a hairpiece 1 and the hairpiece located above it. Its function is not only the to hold the glass but it also creates a vertical distance between a crossbar 3 and the other, and supports them. Assembly time therefore it is reduced since it is no longer necessary to trace in the uprights 2.

The assembly is sequential and follows an order towards above. After immobilizing the uprights 2 in position desired, a first crossbar 3 is fixed to two adjacent uprights 2; then the spacers 4 are placed in the two uprights 2, located above the first two hairpieces 1, then another crossbar 3 is fixed, and this sequence continues until that the facade has been completed.

A second embodiment of the system of union described here, which is also suitable for facades continuous, also provides for the use of a hairpiece 1, a bar profile that is going to create the post 2, of a second profile bar which creates the crossbar 3 and a spacer 4.

In this second example, in addition to coupling the jaw 1.3 and a retention jaw 1.4 opposite to it, the insert 1 is provided with a terminal 1.7. The hairpiece 1 too it is provided with a guide bracket 1.8 located perpendicular to the body 1.1, and looking in the same direction as the corbel of connection 1.2. The second corbel 1.8 is also provided with a terminal 1.9 located at its distal end, and perpendicular to the same bracket 1.8.

The profile bars used to create the 2 uprights each have a double seat 2.2 divided into two channels 2.9 and 2.10, and a fin 2.4, which in this case is thin and flexible. The coupling jaw 2.2 and the retention jaw 2.6 are placed on the same fin 2.4; coupling jaw 2.5 facing channel 2.9 and retention jaw 2.6 facing the retention channel 2.10. At the bottom of the channel 2.10 and looking towards the center of the stile 2, there is a highlight that create an inclined plane 2.7. At the bottom of channel 2.9 and located towards the outer side of the stud 2, a projection 2.11 creates, together with the walls of channel 2.9, accommodation 2.12.

The profile bar used as spacer 4 It is formed by a 4.1 body and two 4.2 brackets. One of the two brackets is provided with a coupling clamp 4.3, while that the other ends in a fin 4.4 located perpendicularly with respect to the bracket itself 4.2. Housing 4.5 of body 4.1 houses a vertical joint 8.

When assembling, the crossbar 3, already equipped with plugs 5 and hairpieces 1 at their ends, it frontally approaches the stud 2. The connection bracket 1.2 of each insert 1 fits in the outermost channel 2.9, and the bracket guide 1.8 on the second channel 2.10, until the claw of coupling 1.3 fits with the coupling claw 2.5. The wingspan of the bracket 1.2 determines its correct coupling with the upright 2. In fact it must be greater than the distance between the lateral end of the jaw 2.5 and the edge of the channel 2.9 (net measure), thus forcing the fin to bend when Insert the connection bracket 1.2 into channel 2.9. When the jaws 1.3 and 2.5 hook each other, fin 2.4 returns to its original position and at the same time pushes the bracket 1.2 against the edge of channel 2.9, opposite of fin 2.4, and forcing the area support 1.4 of the connection bracket 1.3 against the edge rigid 2.13. Eventually, terminal 1.7 is located within the housing 2.12, placed between the edges of channel 2.9 and the highlight 2.11.

The coupling of jaws 1.3 and 2.5 prevents that the hairpiece 1 gets rid of the amount 2. The contact between support area 1.4 and edge 2.13 of channel 2.9, and the contact between terminal 1.7 and housing walls 2.12 prevent the insert 1, and therefore the crossbar 3, from rotating around one of its longitudinal axes.

Screws 6, which also pass through the holes 5.4 of the plug 5 are inserted in the holes 1.6  near the connection bracket, and mark the clamping jaw 2.6. The bracket 1.8 guides the screws 6 into the channel 2.10. The immobilization with screws 6 is therefore performed using the more central channel 2.10 and not the 2.9 in which the corbel 1.2. When inserting screws 6, fin 2.4 is not curve, and its jaw 2.5 does not come off from jaw 1.3 of the connection bracket 1.2.

Both brackets 4.2 are introduced in it channel 2.9 of stud 2 in which bracket 1.2 of the insert 1. Jaw 4.3 is coupled with the coupling jaw 2.5 of the fin 2.4. The flap 4.4 of the other bracket 4.2 is placed in housing 2.12, thereby fixing the spacer 4 to amount 2.

In a third example of system realization of union described here, which is also suitable for facades continuous, the use of a hairpiece 1 of a profile bar is foreseen that will create the post 2, of a second profile bar that creates the crossbar 3 and a spacer 9. These details differ in its shape but have the same characteristics as those They have described previously.

The only variations are the absence of two terminals 1.7 and 1.9, the shape of the spacer 9 and its accommodation in the stud 2. The spacer 9 is provided with two brackets 9.1 and 9.2. The bracket 9.2 is provided with a jaw coupling 9.3. The bracket 9.2 fits on the channel plus peripheral 2.9 of the stud 2, and its coupling jaw 9.3 is joins with coupling clamp 2.5 of channel 2.10. The other bracket 9.1 adjusts on the other channel 2.10.

A second spacer can be used, the spacer 10, which fulfills the dual function of creating a distance  between the crossbars 3 and supporting the elements that hold the doors. It is provided with two brackets 10.1 and 10.2, which are adjusted in another channel 2.14 of the post 2 which has a position different, lateral and a different function, compared to the of channels 2.9 and 2.10, which serve to immobilize both the insert 1 as the spacer 2. The spacer 10 is fixed to the upright 2 by means of the joint 11 which is provided with a relief 11.1 intended to occupy throat 2.15 within channel 2.14.

In a fourth embodiment of the system of union described here, and which is especially suitable for interior moving walls, a hairpiece 1 is used, a bar suitable profile to create the post 2, a second bar of profile to create crossbar 3, and a spacer 12. Also in In this case, the details differ in terms of their shape but present the same characteristics as those described above. The fin 2.4 of the post 2 is not provided with the inclined plane 2.7, the crossbar has only one 3.2 channel, and the 12 spacer It has two brackets, 12.1 and 12.2, one of which is provided with a coupling jaw 9.3. The 12.2 bracket of the spacer 12 embraces the exterior 2. The coupling jaw  12.3 of bracket 12.1 of spacer 12 joins the jaw clamping 2.6 of channel 2.10.

When fixing the insert 1, two fixed 13 are used to prevent the insert 1, and then therefore the crossbar 3, scroll vertically. These fixed are introduced in the 1.6 holes located next to the connection bracket 1.2, where mark jaw 2.6 of fin 2.4. The placement of the fixed 13 ends when its tips come into contact with terminal 1.9 of the guide bracket 1.8, thus creating an end stop. In In this case, the inclined plane 2.7 is not provided. In fact given that the tightness of the interior walls is not needed, it is not  they use plugs, and the fulcrum function doesn't make sense before described for the inclined plane 2.7.
