Definitions
- the invention relates to mast guide carriages, which have two wheels in the vertical displacement direction on one side and an impeller on the opposite side, according to the preamble of claim 1.
- mast guide carriages are usually used on larger yachts, which make the luff of the sails on the rear of the mast along a mast guide track with low rolling friction up and down mobile.
- the mast guide carriages are at a suitable distance from each other at the front of the
- the lowest possible stack height of Mastfuelunsskygen is advantageous in any case and therefore desirable. It brings a compact volume of hull with less wind attack surface and can be dammed because of the lower altitude because of easier and safer, which is decisive in strong winds and small crew.
- the invention proposes to use an asymmetrically shaped mast guide carriage made of suitable material, which is preferably equipped with three wheels at the outer ends, with two wheels on one side of a guide rail as close as possible behind the other run in the same track groove, whereas the third wheel runs on the opposite side in the opposite track groove and controls the contact pressure of the three wheels to each other.
- Each second guide carriage within the designated number has a mirror-image shaped main structure with a correspondingly changing arrangement of the three wheels, so that on each side of the guide rail, the juxtaposed mast guide carriages alternately have one impeller and then two distant wheels in a row.
- the guiding force of the mast guide carriages in the horizontal direction depends directly on the width of the guide rail and depends on the respective product.
- the vertical guide force increases with the growing center distance of the tandem wheels running in the same guide track groove.
- This relatively high space requirement is distributed according to the invention alternately on both opposite guide track grooves.
- the single wheel of each carriage requires only its outer diameter as the space required, so that the average stack height of each carriage composed only of two impeller diameters and half of the executed center distance of the wheels running in the same groove.
- the stack height of each inventive guide carriage reduces the same dimensions by half the center distance of the tandem wheels.
- This arrangement of two intermeshing alternating guideway heights on either side of the vertical guideway allows the stack heights of the mast guideways stacked on one another to be reduced considerably, while maintaining the guidance accuracy and the strength of use.
- three-wheeled carriages ultimately have the same number of wheels on both sides of the guide rail, whose load is distributed to all by mutual support, so that high operational reliability is ensured.
- Fig. 1 shows a plan view of a stacked arrangement of the mast guide carriages.
- FIG. 2 is the side view of the stacked mast guide carriages.
- FIG. 3 is a plan view of the uppermost mast guide carriage of FIG. 2.
- Fig. 1 shows the stackable in use vertical arrangement of a number of mast guide carriages (1) according to the invention.
- each mast guide carriage (1) is symmetrical about its horizontal mounting position or its horizontal center line (6), so that in the final assembly on the mast guide rail (3) every second mast guide carriage (1) must be pushed upside down.
- Fig. 2 is the side view of the stacked mast guide carriages (1) of Fig. 1, in which a necessary distance of the tandem running wheels (4) of a mast guide carriage (1) can be seen, one behind the other on one side of the guide rail (3) in whose guide track groove (11) engage and have to absorb the vertical tilting forces, which requires said distance.
- the single guide wheel (4 a) of the lower inverted mast guide carriage (1) transmits, like all similar, the horizontal forces acting on it and holds the opposite tandem wheels (4) in its guide track groove (11).
- Fig. 3 is a plan view of the uppermost mast guide carriages (1) of Fig. 2 showing an advantageous opposed unequal wheel assembly engaged with a commercially available guide rail (3) provided with two opposed track grooves (11) on a mast (12) is, whose approximately parallel aligned three stub axles (5) in the base plate (2) are fixed, via which the guide wheel (4a) and the tandem wheels (4) are rotatably mounted, for example, suitable plastic.
- a stiffening rib as a wheel guard (13) in front of each guide wheel (4 and 4a) is provided, which provides protection against weather conditions and contact.
- the cantilevered connection tabs (8) which hold by means of lug (10) a sail (7) with its connecting loops (9) movable.
