Description

Attachment of attached box in guides window.

Object of the invention

The present invention consists of an anchor of box attached in window guides that is applicable to boxes of roller blind pickers, cable winch boxes of blind, and the like.

This anchor consists of a special configuration of the fixing elements of the box that allows set such fixation in the window guide either outside or good inside.

The invention characterizes the use of pivots breakable for easy removal when the support plate small box is attached externally.

Similarly, on the anchor wings there is a extreme caged plus a perforation both destined to favor the accommodation of spacing ribs present in the base of the body intended to be housed in the box. This cajeado together with the drilling they establish the same distance between the window and body guide intended to be housed in the box regardless of where the box is placed.

Background of the invention

Tape collector boxes are known of blinds that are attached to the side of the window to house the winding

Among these boxes, it is worth mentioning the one described in the Spanish Patent with publication number ES2151371 consisting of a box specially designed to optimize the winding space while avoiding being damaged by the window when it opens.

Space optimization is carried out projecting the central area outward without exceeding the extra distance allowed by window hinges.

This objective is achieved by establishing a special configuration of the union of the box to the chassis by means of perforated pivots which is where the screws come in fixation.

In this configuration the box is screwed behind the chassis so the screws thread into the inside the chassis pivots to establish the joint by middle of his thread.

The present invention allows prior binding and back of the box with respect to the window guide without making use of two different configurations, not being limited the application of this configuration of the anchorage to boxes of blind tape pickers but it is also a cable winch boxes and the like.

Description of the invention

The present invention consists of an anchor of box attached in window guides. This anchor allows the installation of the box both outside the window guide as inside. The window guide is only a side profile which is part of the window frame. These window frames they can incorporate pre-installed boxes intended to receive roller blinds or lifting lathes of the blinds. With these preinstalled boxes the set is carried directly to the work for fixing.

In the state of the art the use has been cited of pivots that emerge from the base of the box itself so that the Screw joint screw inside this pivot.

The diameter of the pivot must be sufficient as so that the pivot resistance is able to absorb the torsional and tensile stresses or compression that it supports by the screw inlet and tightening.

In the tightening operation, the screw exerts by the entrance of the threads in the internal wall of the pivot an effort mainly of torsion.

Screwdriver tightening and then the axial stress of the screw print a tensile tension and compression respectively to be considered in addition to that of torsion as minimum resistance requirements.

In this invention, means of anchor that allow to arrange the joint surface of the box to the window guide outside or inside. Covering the gap there is a trim that leaves a space that It is usually occupied by the body housing to be installed in the inside the box, for example a lifting lathe of the shutter, or by the blind tape picker.

The present invention considers a configuration of the anchors that allows to attach the box by outside or inside without changing the design of the fixings of the rest of the elements.

This possibility is due to the presence of some breakable pivots on the rear wall of the wings that extend the flat front surface of the box.

These breakable pivots are perforated, with through holes or not, and your mission is to receive the screw of fixing the whole set. Since the screw enters the Pivot drilling by tapping, the pivot has enough resistance to withstand the efforts mentioned previously.

However, these pivots have a weakening that makes them breakable to allow for easy elimination allowing to be attached on the outer face of the guide of the window.

Once removed the pivots breaking them to through the weakening, in the fin on which it was arranged the pivot results in a perforation of greater diameter than allows the passage of the screw so that in this case the screw Thread directly into the window guide.

In turn, the body housing to be installed in the box, for example a roller blind picker, presents in its fixing fins support nerves. By supporting these fins through the nerves, a distance to the guide surface. In the space left by this distancing is where the anchor fin of the box. This distance is independent of whether the box support outside or inside.

For this purpose the anchor fins of the box have some holes and perforations that allow the passage of the nerves of distance from the body to be installed in the box. Thus, in the installation of the box outside the window guide, the fins of the box are always housed in the interior of the space left by the nerves of the body to install in such a way that the box does not impose a separation other than the one already established.

On breakable pivots, if necessary the weakening reinforcement to withstand torque older, the optional incorporation of nerves of reinforcement.

When these nerves are two and they are willing in opposition, they allow the pivot to flex around the points in which reinforcement nerves are found. This flex is which allows easy breakage of the pivot for removal.

The breakable pivots have a first weakening in the step that is established between the two different diameters in the inner hole. This step coincides with the back plane of the box flap so that the fin is larger in diameter so that the screw never thread on it. The coincidence between the plane posterior and the step due to the difference in diameters defined a reduction of the section and therefore defines this first weakening

Optionally it is possible to increase the weakening incorporating for example a perimeter groove in the breakable pivot base.

It is also the object of this invention, the inclusion of additional fixing lugs arranged as prolongation of the major lateral walls. In this case, it they have fixings on either side, not coincidental, to allow the screwdriver to pass without the lug on the side opposite hinder. Some or all of these lugs may be grooved to facilitate screwed connection at one point prefixed.

Examples of embodiment of the invention

The present invention consists of an anchor of box attached in window guides that allows the installation of box inside and outside the front face of the cited guide.

An example of a box is shown in figure 1 (1) incorporating the anchors object of this invention. These anchors consist of fins (1.1) that extend the flat face front on which there are arranged on its back breakable pivots (1.2).

Figure 2 shows the sectional view of a Pivot (1.2) breakable. The breakable pivots (1.2) have a perforation (1.3), through or not, of diameter such that the entrance of the screw (5) is threaded.

On the outer face of the pivot (1.2) breakable, at the root, there is a notch (1.4) of weakening as of perimeter groove that in this example has been carried out according to an angled section whose lower side extends the surface horizontal.

This notch (1.4) of weakening is the which allows easy breakage of the pivot (1.2) for its elimination.

Inside the perforation (1.3) of the pivot (1.2), there is a step (1.5) because the diameter of the perforation on the front side is greater.

In this embodiment, the step (1.5) is placed coinciding with the surface from which the pivot emerges (1.2) breakable so that the weakening occurs right in a horizontal surface so that the break eliminates the pivot (1.2) without leaving any highlight; and in addition, the hole that remains is of larger diameter so that the screw (5) in this case does not thread in it but in the perforation (3.1) of the guide (3). So, in this realization the step (1.5) is but the transition between two diameters

When the torque during screwing is high, the notch reinforcement is considered (1.4) or weakening by one or more nerves (1.7). If use is made of two nerves (1.7), as is the case of the example shown in the Figure 3, it is convenient to arrange these (1.7) in opposition so that  define a hinge line by which, by bending, break more easily the pivot (1.2) breakable.

The fin (1.1) in which the box is extended (1) it also has holes (1.6), perforations (1.8) or both (1.6, 1.8) coinciding with the position of nerves or projections (2.2) on the fins (2.1) of the body (2) to be installed inside of the box (1). These boxes (1.6) may have different configurations that include its perimeter layout on the fin (1.1), or on some flanks of it (1.1) giving place to a reduction of its dimensions.

It is said coincident in the sense that such nerves (2.2) or projections, when the box is fixed to the guide (3) outside the window after removing the pivots (1.2) breakable, by the presence of the cajeados (1.6) and the perforations (1.8), such nerves (2.2) do not rest on the box (1) but on the outer surface of the guide (3) of the window. From In this way, it is also possible to interpret this configuration as that the projections (2.2) establish a separation space that can be occupied by the front part of the box (1) where find their fins (1.1).

If the installation of the box (1) is inside of the guide (3) then the nerves (2.2) or projections remain of support, the body (2) that is installed inside the box (1) is equally distanced and of course also the outer trim (4) remains in the same position with respect to the guide (3) of the window.

Figures 4 and 5 represent an explosion of the set in which the relative position between the window guide (3), the box (1) (inside or outside according to the case), the body (2) installable in the box (1), plus the trim (4) with the screws (5) for fixing the set.

In particular, the details of the union are shown in figures 6 and 7 where:

?

In figure 6 a detail of the first case, the one corresponding to the box (1) installed inside, in which the screw (5) crosses the perforation (3.1) of the window guide (3) without threading, and it reaches the breakable pivot (1.2) that has not been eliminated. Is in the breakable pivot (1.2) where the screw (5) threads compressing the set, from the trim (4) to the box (1), leaving all attached to the guide (3) of the window.

?

Figure 7 shows a detail of the second case, the one corresponding to the box (1) installed outside, in which the breakable pivot (1.2) has been removed to allow installation on the external face of the guide (3). The elimination of the breakable pivot (1.2) results in a drilling a diameter larger than the screw (5) so that it (5) pass without threading and be in the hole (3.1) of the guide (3) where it threads With this arrangement, the box (1) is imprisoned between the body (2) that is introduced into it (1) and the guide (3).

The anchor of the invention is completed with the use of lugs (1.9, 1.10) that allow screwing in the lateral face of the guide.

The side face can be the right or the left, depending on where the box (1) is installed. Lugs (1.9, 1.10) are arranged in pairs and out of date with each other so that one ear does not obstruct over the other when use is made of screwdriver. In addition these lugs (1.9, 1.10) can go grooved to favor correct positioning. In the embodiments shown in the figures have been combined by way of example different configurations: with and without slot; and of the grooved, the direction of the perpendicular grooves between yes.

They do not alter the essentiality of this invention variations in materials, shape, size and arrangement of component elements, described in a non-limiting manner, sufficient this one to proceed to its reproduction by an expert.
