Description

Tester perfected.

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to a treasurer perfected that has been specially designed to be mounted in boxes of motorized blinds, since the doors that exist in the market for this type of axes do not have means of direct anchoring of the roller winding axis and is it is necessary to attach a support to each tester and fix them well with rivets or screws.

It is therefore an object of the invention to provide a tester in which motorized blinds can be connect directly without the need to put supports or have to screw or rivet.

Background of the invention

Conventional heads, in addition to inconveniences reflected in the previous section, and how consequence of its complex structure for the assembly of blinds motorized, presents problems of misalignment between the supports of the blind axis due precisely to the assembly of elements support hairpieces. This also involves a little operation silent and a slower and complicated assembly because you have to Drill and proceed to riveting or screwing the brackets This construction means a higher cost of mounting, in addition to showing the screws of clamping of these roller shaft supports.

Description of the invention

In general, the perfected tester object of the invention has been designed precisely for assembly of motorized blind shafts that are thus coupled directly simply and quickly. The product wins in presence when no screws or rivets appear in sight.

To do this, the central area of the testero where usually the support means of the axis of manual activation of blinds and that if desired motorize it is necessary to mount additional brackets themselves acquaintances; according to the invention includes a central projection perfectly adapted to directly receive the motorized shaft. The central projection has a hole of square section or in general polygonal, adjusted to the spike of identical section that it usually presents the motorized axis of the blind, being located said pin in the housing or stator of the drive motor which It is coupled to the shaft end.

The testeros are usually constructed of plastic material called technical plastic, and there are also metallic

In the case of metal pockets, obtained similar to plastic injection molding, the central projection carrier of the polygonal hole is formed in a neck cylindrical very reinforced since it has on its outer periphery with a plurality of triangular reinforcing partitions, having the inside said cylindrical neck internal partitions in two perpendicular directions that determine when crossing a hole square in this case, with dimensions adjusted to the shape square of the spindle section of the motorized shaft.

In the case where the testator is manufactured in technical plastic or similar, the central projection is materialized by a cylindrical core with a coaxial metal insert that is provided with the hole of square or polygonal section appropriate to the spike to receive inside. The outside of this core Cylindrical is also reinforced with triangular partitions similar to the previous ones in all its periphery.

It is also intended as an improvement in the structure of the testero, that in the front part of the perimeter partition that in a known way exists in all types of conventional testers for the fastening of the tester itself to the box of the blind, torn holes are made to easily allow access to the control points of the motor controlled rotation. The test stands that exist in the market to be able to regulate the motors of automatic actuation, have a flexible plastic rod that must be introduced through the windows of the guides but that it is necessary to bend them in a very complicated way to be able to access the engine regulation points , because these regulation points are very close together and the distance between guide windows is very large. For example, the distance between centers of the regulation points of an engine is approximately
20 mm and the distance to the walls of the blind box is approximately 80 to 90 mm. Due to this difference in measures, access to these regulation points is very difficult.

On the contrary, when these holes exist torn that the invention proposes, is easily and directly accessed  the regulation points of both motors with limit switches mechanic as if they have radio guide that are the immense most.

To facilitate the understanding of characteristics of the invention and forming an integral part of this Descriptive report, accompanying some sheets of plans in whose figures, with an illustrative and non-limiting nature represented the following:

Description of the preferred embodiments

Referring to the numbering adopted in the figures, the improved testero that the invention proposes, as shown in figure 1 presents a very structure similar to the usual one because it has a plate (1) with the perimeter partition (2) that is not continuous but is interrupted in several zones for passage of mounting accessories (manually operated ropes or tapes, access to the slats of blind to the connecting rail with the vertical guides of Sliding the same, motor electrical connection cables motorized drive, etc.). This perimeter partition (2) of the tester is introduced in the respective mouth of the shutter box not shown in the figures and is slightly tucked into the contour.

Well, the basic feature of the invention focuses on the special geometry presented by the central projection (3) that materializes the direct support means of the axis (4) of the motorized blind, without it being necessary use accessory support parts as usual and neither even the use of screws or other fixing means.

The shaft (4) is conventional and has the motor (5) at one of its ends, as seen in figure 3. The housing or stator is anchored without rotation to the central projection (3) of the tester through its prismatic spike (6) that will remain inserted in the hole (7) of analogous section that has been formed for this purpose in the central projection (3). The extreme opposite of this motorized shaft (4) has the octagonal piece of winding tube drag that fits externally in she.

The assembly is direct and simple because it does not require of screws or complementary support accessories, only the shaft (4) must be placed, once inserted into the octagonal tube of rolling the blind, with the help of the retractable end or fixed from the other end. The tester shown in this figure 1 to the that we are referring to is metallic and is built in a single piece injected, forming the polygonal hole (7) in the inside of a cylindrical neck (8) that emerges from the area central plate (1), using pairs of partitions (9) arranged in two perpendicular directions to determine the axial emptying that constitutes the hole (7), in this case of square section, prismatic pin receiver (6) shaft (4) of the blind. As seen in this figure 1, there are also other small reinforcement partitions of the partitions themselves (9).

The cylindrical neck (8) is also found reinforced by triangular partitions (10) distributed in all the outer contour.

The invention also provides that the testator can be made of technical plastic as usual and in this case the hole (7) is formed in a cylindrical core (11) that carries a metal insert (12) with the pin insertion hole (7) (6) of the shaft (4), as clearly seen in Figure 2.

Another feature of the invention that improves the functionality of the driving device, lies in the forecast of two torn holes (13) (see figure 1) arranged in the front front part of the perimeter partition (2), thanks to the which are perfectly accessible to the means of regulation inherent to the engine (5).
