Description

Alignment device for pick-up axles Curtains and similar elements.

The present Utility Model application consists, as indicated in its statement, in a "Device curtain and element pick-up shaft aligner similar ", whose new construction features, conformation and design comply with the regulations with a security and maximum efficiencies

More specifically, the invention relates to a device consisting of three pieces, two of which connect the motor shaft with the axis of the curtain collecting device, and that they are related to each other, by means of a third piece that aligns the collector shaft at the four cardinal points with the axis of the motor, at the same time prevents the collector shaft from experiencing a axial movement out as a result of the effort made against the weight of the curtain, which it picks up.

It is usual in this type of curtain collectors the connection between an axis to which some cords or chains and they to the corresponding curtain, which said axis does not is perfectly aligned with the elements that allow its rotation, this is a consequence of the manufacture of these elements in two pieces, one containing the axis and another containing the motor. The element that contains the axis is formed by a profile  open in the form of "U", inside which are some axle clamping means, as well as turning it in its inside.

At one end of its profile the motor is coupled with a box that contains it and that profile is coupled, consequence This type of construction is that the shaft can never be aligned motor and collector shaft and therefore requires about intermediate elements of alignment and connection between said axes

No background is known in the state of the technique on this type of devices, maybe as consequence of which benefits are imposed on them superior to their function, such as the ease of assembly of axles, their low weight, and the universality in alignment, since the it is secured in all possible positions, avoiding in itself what is an unexpected effect on the axial movement of the collector shaft out, when it turns, winding or unwinding some cords or chains which are usually in solidarity with the curtains and helping their folded or unfolded.

The above benefits are achieved through the special geometric configuration of the device, and at parts that are part of it, which are manufactured in plastic materials preferably, which ensures its manufacture at low cost, configuring the two extremes according to a portion cylindrical that extends through one of its ends in another portion substantially cylindrical of greater diameter, but of smaller width, emerging from this extension in one of them a highlight dovetail section diametral, while in the second presents a diametral cleft to be able to contain a projection longitudinal also in the form of dovetail.

The intermediate piece is configured as a complement of the previous two adopting a configuration substantially low height cylindrical and, preventing in its diametral zone a slit in the shape of a dovetail, and a diametral shoulder of direction perpendicular to the previous one also in the form of a tail of dove

The extreme pieces stand in solidarity with the axes of the motor and collector by means of a screw, which goes through a stud forming a unit with said pieces.

Other details and features will be put manifest in the course of the description that follows it is given, in which reference is made to the drawings that this memory It is accompanied, in which schematically the preferred details, said details are given by way of illustration but not limiting the invention.

Follow below a detailed relationship of the main elements of the invention and that are recorded in the attached figures; (10) dustpan, (11) profile, (11a) wings, (11b) base, (12) wings, (13) motor housing (23), (14) motor connections, (15) collector shaft (10), (16a) cylindrical portion, (16b) portion cylindrical, (16c) base, (16d) protuberance, (16e) cylindrical stud, (17) intermediate piece, (17a) base, (17b) diametral protuberance, (17c) base, (17d) recessed, (18) coupling piece, (18a) part cylindrical, (18b) cylindrical stud, (18c) cylindrical portion, (18d) base, (18e) protuberance, (18f) recessed, (19) screw, (20) screw, (21) crossbar, (22) crossbar, (23) motor, (24) nails, (25) aligners, (26) shaft.

Figure 1 is a side elevational view of the collector (10) at whose end the housing of the engine (23).

Figure 2 is a top plan view of the collector (10), inside which the device can be seen recommended with the axles (15 and 26) coupled thanks to it.

Figure 3 is an exploded perspective of the device according to detail 1 of figure 2.

Figure 4 is a side elevation of detail of the pieces (16-17-18), that make up the shaft alignment device (15 and 26).

In one of the preferred embodiments of what it is the object of this Utility Model and, as it may seen in figures 1 and 2, the collector (10) is formed by a profile (11) whose cross section is a base "U" flat, whose wings extend inwards according to other wings (12) forming a right angle with the previous ones of small width, see Figure 2.

At one end of the profile (11) it is coupled the housing (13) with the help of nails (24), being in the top of (13) the motor junction box (14) (23), inside (13) is a small engine (23) dot marking in figure 1.

Inside the profile (11), as is a conventional solution, aligners are placed (25) substantially cylindrical with the help of the crossbars (21) and (22). The shaft (15) moves through the aligners (25) of the collector (10).

The device of the invention has as its mission join, while aligning, the shaft (26) of the motor (23), with the shaft (15) of the collector (10), which is done with the help of three pieces (16), (17) and (18).

The part (16) is coupled to the motor shaft (26) (23) by means of a screw (20) located on the lateral surface of the cylindrical portion (16a), passing through a cylindrical pin (16a), extending (16a) according to another cylindrical portion (16b), of greater diameter that (16a) but of smaller height, which presents at its base  (16c) a longitudinal tail-shaped bump (16d).

To the axis (15) of the collector (10) the coupling piece (18), which is formed by a portion cylindrical (18a) in which there is a cylindrical nipple (18b) for the passage of a screw (19) that immobilizes (18) the shaft (fifteen).

The cylindrical part (18a) is extended in another cylindrical portion of greater diameter (18b) and smaller height, whose base (18d) has a longitudinal tail-shaped protrusion de milano (18e).

The coupling piece (18) joins (16) by means of an intermediate part (17) of configuration substantially cylindrical, one of whose bases (17a) emerges a bump dovetail shaped diametral while on the other base (17c) a diametral recess (17d) is planned, also in the form Dovetail.

The piece (16) is coupled to the (17) by means of the entrance of the bump (16d) into the recess (17d), as well as the same piece (17) is coupled to the piece (18) when entering the protuberance (17b) in the recess (18f).

Being the bumps (16d) and (17b) diametral and longitudinal allow in combination with the recessed (17d) and (18f) an alignment of the shafts (16) and (15) in any position while coupling with bumps in the shape of a dovetail it retains the shaft (15) against the force that winding strips or cables chains or similar they invite you to an axial movement out by counteracting it.

Suitably described the present invention in correspondence in the attached plans, it is understood that they may introduce any detail modifications to them that are deemed convenient as long as the essence of the invention that is summarized in the following claims.
