HRP20010195A2 - Anchor for small vessels - Google Patents

Description

The field of technology

The invention relates to an anchor used for anchoring smaller vessels.

According to the international classification of patents, the invention belongs to area B 63 B, which includes ships or other vessels and ship's equipment, and is marked with the symbol 21/00 - mooring.

Technical problem

The technical problem solved by this invention is the construction of an anchor that will "hold" equally well on any bottom, better than existing anchors.

State of the art

Until now, several types of anchors are known for smaller vessels. Each of these anchors is most effective on some type of bottom - stone, mud, sand, grass or gravel.

The essence of invention

The essence of the invention is an anchor for smaller vessels that has a lever that turns on both sides at an angle α = 60°. The lever rotates between the arms to the stops that connect the supports. The arms are together with the supports on the base plate of the anchor. Correct functioning of the invention is enabled by precisely defined relationships between the lengths of the sides of the anchor parts at a given angle a. An anchor chain is attached to the lever to lower the anchor.

Figure 4 shows the anchor in perspective as it falls to the bottom

It can be seen from the attached pictures that the anchor for smaller vessels, according to this invention, includes a lever 1, a pin 2, a support 3, a base plate 4, wings 5 and stops 6.

Description of performance and functioning of the invention

Anchor for smaller vessels, Fig. 1. and 2., has a base plate 4 on which, at a certain distance from each other, parallel to the length of the base plate "b", supports 3 are fixed vertically. The supports are connected on the sides by stops 6. The supports have openings in which pivot 2 turns. Between the base plate 4 and the support 3, arms 5 are fixed, whereby the sides "e" of the arms 5 are parallel to the sides "d" of the base plate 4. The arms 5 have a pointed shape in the front part for easier digging into the bottom.

Between the supports 3, a lever 1 is placed, with a narrower side, with a pin 2 through which the lever rotates in the supports 3. The lever can be turned to one or the other side, at an angle α = 60°, i.e. up to the stop 6.

Anchor chain 7 is attached to the other side of the lever.

Letter marks on Fig. 1., 2. and 3. mean:

a = length of arm 5

e - arm width 5

b = length of base plate 4

d = width of base plate 4

c = distance between the axis of the pin 2 and the axis of the hole for the anchor mooring 7 on the lever 1.

f = distance between the upper surface of the base plate 4 and the axis of the pin 2

g = height of supports 3

In order for the anchor for smaller vessels, according to this invention, to function properly, the following relationships between the dimensions of the component parts of the anchor must be observed when making the anchor, namely:

a : e = 2.5

a : b= 1.4

a : d = 2.7

a : c = 0.67

a : f = 10

a : g = 2.5

α = 60°

The dimensions of the arms of this anchor are adjusted so that, as soon as the anchor falls to the bottom, it lies down, i.e. takes a position that guarantees that, as soon as we start dragging it along the bottom, it will start digging into the bottom. The angle a, which in the working position is closed by the arms 5 and the lever 1, is adjusted so that when the load increases (the force with which the vessel pulls the anchor), the entire anchor sinks deeper and deeper into the bottom.

The relationships between the dimensions of the component parts of the anchor set in this way enable the anchor to hold equally well on any bottom (stone, mud, sand, grass, gravel).

The advantages of this anchor derive from this:

- as soon as it falls to the bottom, it is ready to be buried (mud, sand, grass) or stuck (stone)

- it simply breaks through the tangle of grass roots and sinks into the bottom

- the anchor chain cannot be wrapped around the anchor

- the greater the force with which the vessel pulls the anchor, the deeper it is buried and the stronger it is held.

Application of the invention

The anchor for smaller vessels, according to this invention, is intended primarily for anchoring smaller vessels.

Making an anchor is very simple from materials available on the market.

Claims (3)

An anchor for smaller vessels that includes a lever, arms, supports and a base plate, indicated by the fact that supports 3 are fixed to the base plate 4; that the arms 5 are fixed between the base plate 4 and the support 3; that between the supports there is a lever 1 with a pin 2 that is embedded in the supports 3 and with which the lever 1 is turned to one side or the other by an angle α = 60° to the stops 6 that connect the support 3 on the sides. 2. Anchor, according to claim 1, characterized by the fact that said arms 5 on the front part have the shape of a spike; that the arms are fixed perpendicular to the base plate 4 and the support 3, whereby the sides "e" of the arms 5 are parallel to the side "d" of the base plate 4. 3.
