- a reliable attachment of the boom which also at Vibrations or erroneous contact with the boom does not cause actuation of the component achieved that the locking member automatically in the larger area due to attacking weight and / or Spring force comes. If the movement is due to any trained and arbitrarily arranged spring, can the locking member also sideways or up in Interference with the area. Due to the cylindrical formation of the sections of the Locking member and the area will be reliable Recording without tilting the locking member in the Area of the guideway ensured, taking under "cylindrical" any kind of a recess with each other parallel side edges is to be understood.
- a simple and protected arrangement of the component, its Swivel bearing as well as the guideway is thereby achieved that their inclusion in or between rigid Legs of the frame of the front loader or the like he follows. Especially when the linkage is inside the hollow Thigh is provided, it is damaging to external Influences well protected.
- Control element e.g. B. in the manner of a handle, intended.
- Other controls e.g. B. lever or Pedals can also be used.
- An advantageous use of the component is in the Locking a front loader on a tractor, one Off-road vehicle, a landscaping vehicle, a construction or Forest vehicle or the like to see, since there the Ensuring the front loader is properly attached important is.
- a U-shaped frame 10 of a front loader is in the type of a bracket shown, one right and one contains left leg 12 and 14.
- the front loader, of which the Frame 10 is a part usually includes a right and a left post, not shown, on outer, rear portions of legs 12 and 14 are welded and have lower end portions that opposite sides of an agricultural tractor, not shown to be attached to consoles; however, is from that Agricultural tractor a weight carrier forming its front part 15 shown.
- the frame 10 has a U-shaped Bracket section 16, between the front end sections the leg 12, 14 is connected and a component 18 picks up between right and left, upright, each leg-forming plates 20, 22, extends and from a plate with a cross section in the shape of a reverse L is formed.
- the component 18 has the function a bolt and can be swiveled around a horizontal axis arranged by axially aligned pivot bolts in the Plates 20, 22 is defined, of which only the right pivot pin 24 can be seen.
- the component 18 is between one shown in solid lines Locked position and one in broken lines shown release position pivotable. If component 18 assumes the locking position, a first extends Leg 26 of it horizontally over the weight carrier 15 and lies on the ceiling surface, while a second leg 30 runs upright in front of the weight carrier 15.
- a device 32 for actuating the Component 18 is provided to an operator in the Able to displace component 18 from a remote location near or on an operating platform of the agricultural tractor, to which the frame 10 is removably attached from between its locking position and its release position swivel.
- the left and right legs 12 and 14 of the frame 10 tubular, and the device 32nd contains a rod 34 in the manner of a cylindrical rod, which is located within the right leg 12; however, a cable could also be a liquid column or the like can be used as linkage 34.
- An eyelet 36 forms the front end of the linkage 34 and is by means of a Bolt 38 and a locking pin 40 pivotally to the outer end of a lever arm 41 connected to the Swivel pin 24 is welded and from this after extends above.
- Locking member 42 has an upper and a lower section 44 and 46, which are in between constricted portion 48 are connected together, wherein the lower section 44 has the same diameter as the upper one Section 46 has and threads on the rear End of the linkage 34 is adjustable.
- One as a handle trained control element 50 in the form of a cranked flat iron is at 52 on top of the Screwed locking member 42.
- the top of the right leg 12 of the frame 10 is with a Provided guideway 54 longitudinal slot, which in a enlarged rear, in this case at the end of the Guide path 54 located end portion 56 passes.
- This End portion 56 is sized to be the upper portion 46 of the locking member 42 can accommodate during the remaining part of the guideway 54 slightly larger than the diameter of the constricted section 48 is dimensioned, so that the latter freely along the guideway 54th can move.
- the control element 50 serves, among other things the locking member 42 within the guideway 54 to keep. It can be seen that with front loaders with others as tubular legs 12, 14 or other frame parts in the guideway 54 also in the vicinity of the operating platform any other usable surface of the leg then given could be incorporated. If the component 18 its In the locked position, the linkage 34 is below Train or tension, the locking member 42 with its upper section 46 in a locking position in the enlarged rear end portion 56 of the guideway 54 is located.
- the weight of the linkage 34 and the locking member 42 can basically be considered sufficient, the upper section 46 of the locking member 42 in its to hold the locking position.
- one in this case designed as a leaf spring 58 on the Linkage 34 mounted, i. H. put on that between the upper inner surface of the leg 12 and the linkage 34 can act and an upward movement of the locking member 42 resists.
- the rear section of the Spring 58 from an area 60 which is U-shaped in side view formed, the legs of which are aligned holes contain the linkage 34 in itself and between them the receive the lower portion 44 of the locking member 42. In their untensioned condition, as shown in FIGS.
- the spring 58 has a straight one Intermediate part 62 which, starting from the front, i.e. H. in the left leg of the drawing of the U-shaped area 60 is angled upwards and forwards.
- the spring 58 has one front end section, which is rounded and curved portion 64 is formed which is the upper inner surface of the leg 12 touches and provided with a sliding groove 66 is.
- the sliding groove 66 follows the shape of the linkage 34 so that the linkage 34 enters the sliding groove 66 when the Intermediate part 62 is directed downward, which is the case is when the locking member 42 is raised to the constricted portion 48 engages the rest of the Bring guideway 54, which extends from the area 56 extends forward as shown in Figure 4.
- the spring 58 preferably and as in the drawing shown is designed as a leaf spring with which the Locking member 42 compliant in its Locked position would be held instead a coil spring between the upper inner surface of the leg 12 and the lower portion 44 of the locking member 42 function inevitably into the locking member 42 to keep the locking position.
- the linkage 34 can be released from the bolt 38 and into the Locking member 42 screwed in or out of this to make an adjustment that may be required to lock the 42 in its locking position in the rear end region 56 to position the guideway 54 when the component 18 is in its locking position.
