Definitions
- the invention relates to a loader with a post for fastening on a vehicle, using one or more consoles and the consoles in their mouths.
- the object on which the invention is based is seen in a connection to be made without tools the loader and the device carrying it without much effort create.
- a line inclined to a horizontal line on the the most distant points of the cross section of the Consoles lie, does not extend in the direction of force application of the loader, so that the positive connection not by the action of external forces when loading or Unloading can be solved. Rather, the posts only be brought into a position in which the mouths release the consoles.
- a pin, a pin, a nose, a projection or the like and in the post a recess or vice versa can be provided by means of this second positive connection of the loader on the Centered, guided and against a transverse console Movement are secured.
- the arrangement of the pin or the same, especially on the back of the console it is easy to place the loader on the consoles almost anywhere and then into the preferably V-shaped recess to tilt in and thus to center.
- a console with a maximum and a minimum distance can be created if this is from a tube or solid material, in particular square or oval cross-section is formed. However, too a rectangular, triangular or other cross section useful.
- the arrangement of a front surface of the console under the claimed inclination is related to the inclination the line through the bodies and granted a form-fitting Connection of the loader on the consoles in the normal operating position.
- the loader can be connected by means of a further contact surface additionally support so that the permissible surface pressure do not exceed the other points or contact areas becomes.
- FIG. 1 shows a vehicle 10 in the manner of a field, lawn or municipal tractor or the like with a frame 12, which is powered by a pair of front and a pair Rear wheels 16 and 14 are supported on the floor and is moved by these.
- a loader 18 is equipped with horizontal rear brackets 20 or cross braces from opposite Out of sides of the frame 12, and with a Front weight carrier or other structure that is not is visibly attached to the front end of the frame 12, connectable.
- the loader 18 is symmetrical to a central one Longitudinal axis and includes a pair of upright Post 22 (only the right post of which is visible is) located on opposite sides of the vehicle 10 are located, the lower ends of the posts 22 on the rear consoles 20 are releasably secured in a manner, which is described in detail below.
- a U-shaped The strut 24 has legs 26 which face each other Sides of the vehicle 10 lie with their rear ends the inside of the posts 22 spaced from the top and the front ends of which are connected by a bent part, that from an integrated parking stand and a detachable one Holding structure exists and thereafter assembling the holder and park 28 is called.
- the bracket and parking assembly 28 is detachable on a front weight carrier or other structure secured to the frame 12 or part thereof is.
- Loader 18 includes a pair of loader arms 30 that correspond the posts 22 are aligned longitudinally and their rear ends pivot in bearings 32 at the upper ends attack the post 22 to allow vertical movement.
- Each of a pair of lifting cylinders 34 is one between one of the posts 22 and an adjacent loader arm 30 attached and extendable or retractable to raise and lower the loader arms 30 to enable their storage 32.
- a Bucket 36 is pivotable at the front end of loader arms 30 attached, and a pair of bucket cylinders 38 is between the loader arms 30 and the bucket 36 are arranged.
- the present invention relates to the manner in which the posts 22 attached to the rear brackets 20 are.
- the rear consoles 20, such as shown in Figures 2 and 3, from tubes with a square cross-section made with each console 20 so aligned is that a front and back surface 39 and 40 make an angle of about 18 degrees with the vertical while top and bottom surfaces 42 and 44 form an angle of about 18 Include degrees with the horizontal.
- Below the horizontal the plane of the footprint of the vehicle 10 and vertical understood the perpendicular to it.
- the post 22 is formed by a rail open at the front, a cast or forged one at the lower end of each Bracket 46 with an open mouth 50 or Sensor is welded, which is shaped so that it Post 22 can hold on the brackets 20.
- Each mouth 50 contains one further contact surface 60 arranged between the others, that comes into contact with the console 20 at one point, those above the upper rear corner 62, which are marked by the Intersection of the top and back surfaces 42 and 40 is formed, lies.
- the mouths 50 are each with indentations, gaps, Provide relief bays or undercut areas that the mouth 50 between the contact surfaces 52, 56, 60 are a certain distance from the console 20 and make it possible to tilt the posts 22 forward and them from the consoles in the manner described in detail below 20 to lift when the loader 18 is removed from the vehicle 10 shall be.
- each mouth 50 contains one front arcuate undercut surface 64 which is between the front and further contact surfaces 52 and 60 extends, as well as a rear arcuate undercut surface 66, which is between the further and the rear Contact surface 60 and 56 is located.
- Figure 3 shows in the rear wall of each bracket 46 an inverted or after V-shaped recess 70 open at the bottom for centering, and on the rear surface 40 of the rear console 20 a pin 72 is provided which is at the top in the recess 70 is placed.
- the loader 18 is on the Vehicle 10, as shown in Figure 1, i.e. i.e., the Posts 22 are each in an upright position in which the consoles 20 are in the mouths 50 and a release is prevented by these by the front and rear Contact surface 52 and 56 at locations below the upper front and rear corners 54 and 58 are located their distance from each other is less than the diagonal Distance, d. H. the maximum distance between the two Corners 54 and 58 of console 20.
- the lifting cylinders 34 for lowering the loader arms 30 actuated to place the bucket 36 on the ground.
- a Jack of the combined holder and parking assembly 28 will then from a holder placed on the vehicle 10 released, and the lift cylinders 34 continue the U-shaped Strut 26 together with the posts 22 over the brackets 20 to pivot that the holder and parking assembly 28 comes into contact with the ground.
- the mouths 50 pass through the positions shown in Figure 4, 5 and 6, so that the Contact surfaces 52 and 56 along the console 20 to the location move, which is shown in Figure 6 by further The lifting cylinders 34 extend freely from the console 20 be lifted off.
- the loader hydraulics is released and the vehicle 10 reset without the loader 18.
- the loader 18 is now through the holder and parking assembly 28 and the shovel 36 held. If necessary, the lifting cylinders 34 can be actuated to lower the posts 22 to the bottom.
- the mouths 50 and 20 consoles can be carried out in other equivalent forms.
- the mouths 50 can, for example, be C-shaped be, with brackets 20 which have an oval cross-section. These are aligned so that the contact surfaces 52, 56, which limit the front and back of the mouth 50, with the consoles at locations below the main axis of the oval Cross section in contact so the posts 22 to secure the consoles 20.
