Roller support for sliding doors.

The present invention relates to a support of roller doors, consisting of one piece approximately U-shaped carrier in cross section, a whose side wings serves as a mounting plate for the fixing a sliding door, and on its other side wing is at least one sheave is fixed, the support of sheaves with insurance against deranging to prevent a unthinkable deranging of a sliding door. It is known a similar support of rollers, for the document US-A-4 281 435.

Basically it is known to provide the doors sliding with insurance against deranging to prevent a sliding door can become unhinged with its guide rails An unthinkable deranging of a door Sliding, damages not only the functional safety of a door Sliding, but in the worst case, you can also drive to accidents, and for these reasons it has to be prevented absolutely.

To this end, designs have been announced in those who install security elements in a sliding door that prevent an unthinkable deranging of the sliding door. Solutions are also known in which elements are provided. of security in the same supports of rollers of a door sliding.

The present invention is based on a concept Basic of the type mentioned above.

The mission of the invention is to create a support of sheaves with insurance against de-gestation simply structured, that presents a small need for space and be Easy to maneuver, as well as robust.

This mission is solved according to the invention, causing the insurance against deranging to be composed of a molded part with a secure bay arm, resting on the soul centerpiece of the carrier, movable parallel to the axis of the roldana or of the roldanas, whose bay extends in the direction of the lateral wing carrying the sheave or sheaves, and that in a possible terminal position of movement, grab by underneath a rib or flange of a guide rail that houses the tread or the rollers, and in their other terminal position of displacement, it is located outside the nerve covering area or the flange.

A roller support with insurance against deconstruction formed in such a way, presents a structure simple and not complicated, since a molded part, movable with a secure bay arm, it is relatively easy to mount on the carrier part of the roller support, the maneuver against deranging insurance is comparatively simple to perform, by moving the part forward and backward molded, which can also be imagined without more, without the help of a tool.

Deranking insurance knows basically just two functional states, the insurance position and the uninsured position. Based on this structure simple, deranging insurance is also extraordinarily robust, and can not get out of position insurance for jerks, bumps or the like.

The following is now described first with reference to figures 1-12, a first example of realization of the invention.

Figure 1 shows a representation in perspective of a roller holder 1 according to the invention, which it is fixed to a sliding door 2 outlined with dotted lines and strokes, and that is enquiciado with a roller 3 in a lane 4 of guide.

The roller holder 1 is provided with a insurance 5 against deranging, by which you can prevent that the sliding door 2 can be removed from lane 4 of guide.

The roller holder 1 is composed in essential of a carrier piece provided with the symbol 6 of reference, as well as the roller 3 and the aforementioned insurance 5 against deranging

The carrier piece 6 has a section Essentially U-shaped, serving a 6th wing side of carrier part 6, for fixing on door 2 sliding, and carrying the other side wing 6b, the roller 3.

Insurance 5 against deranging is supported movable in the central core 6c of the support 6, and by the way parallel to the axis of the roller 3 or -expressed otherwise- perpendicular to the plane of the sliding door 2.

Insurance 5 against deranging consists of a molded part 7 preferably made of plastic, and it presents a bay 7a of the insurance that extends in the direction of the lateral wing 6b of the carrier piece 6, which carries the roller 3. This insurance bay 7a, with insurance 5 against deranging displaced to its safe position, grab below a 4th nerve or a corresponding flange of the guide rail 4 that houses the roller 3, and thus prevents the roller 3 from lane 4 from being picked up as guide. Naturally you have to make sure here that the distance vertical between insurance bay 7a and lane 4a rib 4a guide, is less than the depth of penetration of the roller 3 in guide rail 4.

In figure 2, the molded part 7 that constitutes the insurance 5 against deranking, is displaced in its insurance position, that is, insurance 7a of the insurance grabs below the rib 4a of the guide rail 4.

From this safe position, part 7 molded can be pulled out in the direction of the door 2 sliding, then the insurance bay 7a is located at this uninsured position, outside the coverage area of the 4th nerve In this position it is possible then without more, a conscious deranging of sliding door 2, lane 4 as guide.

In the embodiment shown, the 1 roller support, is equipped with a single roller 3.

Alternatively to this, as is natural in the 1 roller support can also be provided with two or more rollers 3, it is expressly noted that as an alternative to one or several rollers, can also be fixed to the skates support, which then they slide in a guide rail 4. Also an embodiment such can be secured against an unthinkable deranging of a sliding door 2, by means of the lock 5 described against deranging

Insurance 5 against deranging can move without more hand, without tools, taking for granted that in the area of the upper front edge of the door 2 Sliding, there is enough space available to be able to grab the molded part 7. The molded part 7 is provided both in the area from its upper front edge turned towards the roller 3, as also in the front edge furthest from this roller, with aids  presses in the form, for example, of a recessed handle 7b, or of a chamfered striated front edge 7c, which facilitate the displacement of molded part 7 in the desired direction in each case.

Figure 2 also clarifies that if necessary there is also the possibility of moving the molded part 7 out, with the help of a tool 8, from the bottom of the roller holder 1. The molded part 7 is conditioned so that a drive or displacement can be performed also, seen from the upper face of the roller holder 1, with the help of a tool, for this purpose they can be provided, by example, the side flanks of the molded part 7, which run parallel to the direction of travel, with 7d shrouds in the that a tool can be introduced in order to move the molded part 7.

In the exemplary embodiment according to figures 1 at 12, the molded part 7 is crossed by a pin 9 joined with the carrier piece 6 - said more exactly with its core soul 6c -, which is provided at its end located furthest from the soul 6c central, with a safety head 9a, whose diameter is greater than the diameter of the rest of the stud 9.

This safety head 9a is located in the area of a groove 10 of the groove of the molded part 7, and ends with the surface of molded part 7.

The stud 9 passes through the molded part 7 in the zone of an elongated hole 11 which determines in this aspect the maximum possible displacement of molded part 7.

         \ newpage
      

As can be seen in particular in the figure 12a, the elongated hole 11 is provided in its central zone with a narrowing that, however, is elastically conditioned flexible through 12 free cuts.

Thanks to this flexible narrowing, the situation occurs that a displacement of the molded part 7 is always carried out to a possible terminal position, since the narrowing when moving the molded part 7 over the pin 9 requires a certain consumption of force, and after overcoming the narrowing, the antagonistic forces that are now released, favor and promote the displacement of the molded part 7 to a possible position
terminal. At the same time, a casual displacement of the molded part by shaking, knocking or the like is prevented.

So molded part 7 can only always adopt a possible terminal position, namely a secured or uninsured position, referred to the effect purported of insurance 5 against deranging.

In the embodiment of the invention, according to figures 1 to 12, the molded part 7 rests on the face upper core 6c of the carrier piece 6, and the area of the molded part 7 presenting the insurance bay 7a, is layered down.

This area of molded part 7, angled towards below is located in the area of a recess 13 in the area of agreement between the central core 6c and the lateral wing 6b that carries the roller 3, presenting piece 7 molded on its front face located in the area of the lateral wing 6b, directed support ribs 14 down, that with the molded part 7 that is in uninsured position, rely on the 6d edge of wing support 6b lateral, formed by the recess 13. This can be recognized very clearly, among others, in figure 5.

Thanks to this support of the piece 7 molded in the insurance status, in the most unfavorable case - namely, at bump the insurance bay 7a on the 4th rib of lane 4 of guide - molded part 7 can only be ordered from compression, so that molded part 7 can be configured Globally small and yet undergo heavy loads.

Another example is shown in Figures 13 to 24 of embodiment of the invention, which differs from the form of embodiment according to figures 1 to 12, only because the union between molded part 7 and support 6, it is resolved from another so as in the first described embodiment. By this reason, then you enter only the different conditioning, since all the other principles of design, coincide with the example of embodiment already described.

Figures 13 to 24 clarify that piece 7 molded is provided on its lower face turned towards the soul 6c center of the carrier piece 6, with a slotted hollow pin 15 axially, preferably formed of a single piece, with a 16 circular and protruding flange, formed at its free end. The axially slotted hollow pin 15 is placed in a state mounted, inside an elongated hole 11a of the central core 16c, presenting once again the elongated hole 11a, a narrowing in its central zone. The flange 16 grabs below at the end free from the hollow 15, the lower face of the central core 6c.

Thus the molded part 7 can be moved with respect to the central core 6c within the boundaries of hole 11a elongated, and adopts here or an insurance position in which the Saledizo 7a of the insurance grabs underneath a 4th nerve or a flange of a guide rail, insuring against deranging, or a ramshackle position, in which, insurance bay 7a is located outside the nerve covering area 4a of a lane 4 as guide.

The placement of the 16 slotted hollow pin axially, in the elongated hole 11a, it is possible by means of a slot 17 in the area of agreement between the elongated hole 11a and a recess 13 in the area of agreement between the central soul 6c and the lateral wing 6b carrying the roller 3.

Also in the embodiment example of the invention according to figures 25-37, the operation and mode of action of insurance 5 against de-inquisition, in the form of a molded part 7 supported movable on the carrier part 6, they are identical with the embodiments described above. Also here the molded part 7 presents a bay 7a of the insurance that for the purpose of insurance against deranging, you can move below a nerve 4a of a guide rail.

Different in the embodiment according to the Figures 25 to 37, is only the support of molded part 7 with respect to the carrier part 6.

The carrier piece 6, in the area of agreement between its lateral wing 6b carrying the roller 3, and over an area partial of the central soul 6c that joins it, is provided with a recess 13a almost through to its width. This recess It is equipped in the central 6c core area, with two bulges 13b located one after another. The molded part 7 is equipped in its lateral area with guide grooves 7e, as well as with sectors 7f annulars supported in the plane of these guide grooves 7e, and elastically compressible (see especially the figures 34a-35c), and so you can wrap guiding, the zones Margins of the recess 13a located in the zone of the soul 6c central, as clarified in Figure 27.

The elastic annular sectors 7f are sized in accordance with the bulges 13b and, at move the molded part 7, fit each in the bulges 13b anterior, or in subsequent ones, so that once again the two possible terminal positions of the molded part 7. It is here once again the position of insurance in which the bay 7a of the insurance grabs underneath a 4th nerve or a flange of a guide rail, as well as a uninsured or loose position, within which the bay 7a of the insurance is outside the coverage area of the aforementioned nerve or flange of a guide rail.

The different embodiments of the invention, described above, thus differ from some of others, solely because of the form and manner of support and possibility of displacement of molded part 7 with respect to part 6 carrier

With regard to its operation, all designs shown are identical, and in this sense produce the Same advantages.

Of course you can imagine and others are possible embodiments with respect to the movable support of a molded part 7 in relation to a carrier part 6.

The described embodiments above they should only illustrate that there is a multitude of constructive possibilities in the sense of support movable part 7 molded with respect to part 6 carrier
