RU2370405C1 - Portable anchor - Google Patents

Abstract

FIELD: mechanics.

SUBSTANCE: invention relates to ground supports and may be used for retaining small vessels in water basins. The portable anchor contains shank, cross-piece with folded flukes being hinge-installed on the said cross piece. The cross-piece is implemented as rectangular upper and lower plates, which are interconnected by bolts. The shank is rigidly mounted on the upper plate, while angular bars are fixed underneath and provided with hinge-connected flukes. Pinions are fixed to the free ends of flukes. Deployment angle restrictor made up from angular bars is available inside the cross-piece. Toothed racks are installed between bars and contact toothed wheels. The cylindrical rod with rim is installed inside deployment angle restrictor with its one free end being threaded inside restrictor body. The other rod with grooves is located in the central hole of the lower plate and provided with thrust installed on the lower plate at its external side.

EFFECT: simplified manufacture and operation.

Description

The invention relates to bottom supports and can be used to hold in place small vessels in reservoirs.

Known technical solutions (AS No. 872374, No. 953233, No. 965880 No. 1024352, No. 1030245, No. 1087409, No. 1119914, No. 113466, No. 1421603, MKI B63B 21/36) containing a spindle, a spider with folding legs.

Their main disadvantage is the difficulty of manufacturing.

The closest in technical essence is the device (AS No. 901150, MKI B63B 21/36), containing a spindle having a lower head and a cross with articulated folding collapsible legs with a limited opening angle.

The main disadvantage of this device is the complexity of the manufacture of the structure.

The purpose of the invention is to simplify the manufacture and operation of the device.

This goal is achieved by the fact that the crosspiece of the device is made of the upper and lower plates of a rectangular shape, interconnected by means of a bolt connection, while the spindle is rigidly fixed on the top plate, and the angular-shaped posts with pivotally mounted paws are rigidly mounted on the bottom, at the free ends which gears are rigidly fixed, and inside the crosspiece there is a paw opening angle limiter, consisting of angular-shaped struts, between which gear racks included in the contour are rigidly fixed t with toothed wheels, wherein the stopper is mounted inside the cylindrical stem flange, one free end of which is fixed by a threaded connection, and the other with recesses arranged in the central hole of the lower plate is associated with the stopper mounted on the lower plate crosses the outside.

The invention is illustrated by drawings, where in Fig.1 shows a bottom view in the unfolded state (section); figure 2 is a side view in the unfolded state; figure 3 is a side view in the folded state.

In the present invention, the crosspiece of the device is made of upper 1 and lower 2 rectangular plates connected to each other by bolt connection 3, while on the upper plate spindle 4 is rigidly fixed on top, and angular-shaped posts 5 are rigidly mounted on the bottom with pivotally mounted paws 6, on the free ends of which gears 7 are rigidly fixed, and inside the crosspiece there is a paw opening angle limiter consisting of angular shape posts 8, between which gear racks 9 are included act with gears 7, while inside the limiter there is a cylindrical rod 10 with a shoulder 11, one free end of which is fixed by means of a threaded connection 12, and the other with grooves 13, located in the Central hole 14 of the lower plate, 2 is connected with the stopper 15 mounted on the bottom cross plate on the outside.

The device is mounted as follows. If the anchor is in the transport position (in the folded position of FIG. 3), then the stopper 15 is released to bring it into working condition, the limiter of the opening angle of the legs is raised, due to the movement of the gear racks 9, the gears 7 and, therefore, the legs 6 are rotated. They take a horizontal position. Then the stopper 15 is again put into place, fixing the stop, thereby rigidly fixing the entire structure of the device. The anchor is ready to go.

At the same time, minimal time is spent on preparing the anchor for work and on its dismantling, and when folded, it is compact and convenient for transportation.

Claims (1)

A folding anchor containing a spindle, a crosspiece with articulated folding legs, characterized in that the crosspiece of the device is made of the upper and lower plates of a rectangular shape, interconnected by means of a bolt connection, while on the upper plate the spindle is rigidly fixed from above, and the bottom are rigidly mounted angular-shaped racks with pivotally mounted paws, gears are rigidly fixed at the free ends of the legs, and a paw opening angle limiter consisting of angles in the shape of a cylinder, between which gear racks are firmly fixed, which come into contact with gears, while a cylindrical rod with a shoulder is installed inside the limiter, one free end of which is fixed by a threaded connection in the limiter body and the other with grooves located in the central hole of the lower plate , connected with a stopper mounted on the bottom plate of the cross from the outside.
