ES2561902A1 - Extendable guide rail for cameras (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Guide rail (1) extendable for cameras; of the type comprising a calibrated main base (2) on which are mounted parallel guides (3) equally calibrated by which runs a carriage (4) with at least one standard platform (5) for mounting a camera, which additionally comprises additional bases (2a, 2b) removable in continuity with the main base (2), and comprising coplanar mounting means of the additional bases (2a, 2b) and means of continuity of the guides (3).

For its part, the carriage (4) (see fig. 6) comprises means of full contact - that is, without play or play - with the guides (3) in the two axes perpendicular to the longitudinal direction of the guides (3) , to avoid any relative movement of the car in these two axes, and that

5 also prevent derailment of the car (4). Said full contact means ideally comprise vertical shaft bearings (25) whose tracks (26) are penetrating fully into lateral grooves (27) of the guides (3), the tracks (26) and the lateral grooves ( 27) complementary section to ensure full contact.

10 In relation to the bases (2, 2a, 2b), they may comprise lower support means, not shown, on a floor or firm, such as rotating universal bases for tripods, height-adjustable leveling feet, etc.

The invention has provided the additional and optional arrangement of drive means

15 automatic carriage (4), comprising in this example of the invention two terminals (28, 29) (see figs 1, 2 and 4) attachable at the ends of the guide rail (1) formed, comprising a first terminal (28 ) with a motor (30) driving a first pulley (31) or gear, and an opposite second terminal (29) comprising a second pulley (33) or forwarding gear, running between the first pulley (31) and the second pulley (33) a cable

20 (34), belt and / or chain, to one of whose branches (34a) the carriage (4) is attached, so that the motor drive (30) causes the carriage to be dragged (4). The motor (30) is ideally governed by an electronic controller (36), governed in turn by a terminal, not shown, which can be dedicated, or be a laptop, smartphone, tablet, etc. It can also include conventional electromechanical elements, such as

25 limit switches, encoders (60), laser meters, etc. to define routes and pauses of the movement automatically in cooperation with the electronic controller (36). For the connection of the terminals (28, 29) to the rest of the configured guide rail (1), the lateral projecting projections (14) of the guides (3) belonging to the extreme bases on holes (38) will preferably be fixed for this purpose. provided in the terminals (28, 29), as seen in the

30 figures

Additionally, it is provided that the configured guide rail (1) may comprise extreme magnetic stops, for example first magnets (35) mounted at the ends of the rail

guide (1), of reverse polarity to other second magnets (37) mounted on the carriage (4) for braking without mechanical shock, by magnetic repulsion.

In the materials, it is expected that ideally the main base (2) and / or the bases

Additional 5 (2a, 2b) ideally comprise aluminum plates with lower ribs, not shown, which ensure coplanarity, and the guides (3) can be made of hardened steel.

Describe sufficiently the nature of the invention, as well as the manner in which it is carried out in

In practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
