FR2865713A1 - Flat type marine anchor units assembling device, has anchor stock received through orifices of anchor shank, keel skeg and anchor palms, where skeg has oblong hole that frees clamp for permitting passage of sand or silt streams - Google Patents

Abstract

The device has a side (2) disposed on top part of anchor palms (1) and provided to slide in a groove (3) of a keel skeg until to a stop end (4). An anchor stock (8) is received through orifices (5) of the palms, orifices (6) of the keel skeg, and orifices (7) of an anchor shank (12). The keel skeg has an oblong hole (9) that frees a clamp (10) for permitting passage of sand or silt streams through interior of hole during penetration.

Description

  The present invention relates to a method of assembling the constituent elements of a dismountable marine anchor of the flat type.

  Since the ancient times of navigation, appeared the need to be able to cling to the bottom of the sea. In order to fulfill this function, were born different types of anchors, the main ones being the anchors with jas, the flat anchors, or the anchors "soc".

  The present invention relates to flat anchors.

  These were first created in a concept of weight to get a sink in the seabed by thixotropy phenomenon .. (the anchor is its defile). The study then focused on the geometry in order to first obtain a tilting of the legs at the time of taking and then a deep depression to find a more compact ground surface.

  Soon, it is: - we managed to give more importance to the geometry than the weight which allowed to develop so-called lightweight anchors made of aluminum alloy, magnesium, titanium. Their performance is surprising. The first of these anchors, appeared in the nautical, is American, baptized "Fortress" resulting from the anchor Danforth "strongly diffused in the USA.

  The lightweight anchor has become invaluable on board pleasure craft especially when it is easily removable and easy to store. Which is not the case of the Fortress. The heel virtually non-existent does not sufficiently cause the flip-flops, which are fixed to the jas by screw collars. This means that at each assembly operation, it is necessary to unscrew and screw on the retaining straps. On the other hand, the jas is very long, which does not promote storage without disassembly. The second light anchor of the boating is the Foblight '", which is a light alloy version, made removable KRAP Anchor (Patent R6yer :): protected by French patent N 92 05332 The problem posed by the assembly device of this light anchor comes from the fact that it does not leave much passage to the nets of sand during the deep penetration.

  The assembly device object of the present invention, releases the heel by reducing the equivalent braking surface opposing penetration. The accompanying drawings illustrate the invention. - 2 -

  1 shows in perspective the device of the invention, assembled anchor.

  Figure 2 shows in longitudinal section, the heel, the legs, the angular opening rod and the assembly jas.

  Figure 3 is an exploded assembly node.

  Figure 4 shows in cross section the body of the heel.

  Figure 5 shows the crossbar that causes the flip-flop and stabilizing flow "corridor" which together, decreases the brake to the deep penetration.

  The main features of the assembled assembly to bring together the constituent elements of the anchor: legs, rod, heel and jas, to make it removable, include the legs (1), which at their upper part have a record (2) provided for sliding in a groove (3) of the heel, until it comes to end stops (4). The assembled assembly receives through the orifices, (5) for the legs, (6) for the taIon, (5) 7) for the rod 12, the Jas (8) which is at the same time: assembly member held in place by the pin (11), axis of articulation and transverse stabilizing factor during penetration.

  The bezel (9) of the heel is in this way completely clear, leaving free the barrel (10) which causes the flip of the legs at the time of the decision.

  Thus, during the attack of the bottom, the heel causes tilting tips to get the most favorable angle of penetration, given the nature of the bottom. The traction exerted by the ship under the effect of wind, swell, and current causes the anchor to sink towards the more resistant layers of the ground.

  Only the heel, necessary at the time of the catch, then opposes the deep depression. It then becomes important to reduce the equivalent braking surface of this heel. It is the object of the present invention to clear the space, left free for the passage of nets of sand or mud, and guide their flow inside the side gussets of the heel.

Claims (3)

- 3 - CLAIMS   1 / Device for easily assembling the constituent members of a marine anchor flat anchor type, characterized in that it comprises surveys (2) on the upper inner edges of the lugs (1) provided for sliding in the grooves of the heel removable (3) to come on end stop (4) and receive through the orifices (5) of the tabs, (6) of the heel, (7) of the rod (12), the jas (8) which constitutes jointly; assembly member, hinge pin, and stabilizer during deep penetration.   2 / Apparatus according to claim.1, characterized in that it releases the heel to leave free the barrel (10) thereof causing the flip-flops (1) and allowing the passage of the nets of sand or mud by the inside of the telescope (9) at the moment of penetration.   3 / Apparatus according to claim 1 wherein the assembly easily performed, is held in position by a single pin (11) passed in the jas.
