Quick coupling with improved visibility
Described is an attachment device ( 1 ) for telehandlers ( 100 ) designed to be connected to an operating arm ( 101 ) and comprising a front frame ( 12 ) designed for removably attaching an accessory ( 102 ) for engaging a load, such as a fork, a side shift carriage, a winch or a loading platform. The frame comprises two lateral sides ( 121 ) and two crosspieces ( 122 ), of which one upper and one lower, which join the side elements ( 121 ) to each other. One or more crosspieces ( 122 ) have an oblique inner side ( 120 ) relative to a horizontal plane.
1. An attachment device ( 1 ) for a telehandler ( 100 ) designed to be connected to an operating arm ( 101 ) of the telehandler ( 100 ) and comprising
a front frame ( 12 ) designed for removably attaching an accessory ( 102 ) for engaging a load, such as a fork,
a side shift carriage,
a winch or a loading platform,
wherein said frame comprises two lateral side elements ( 121 ) and two crosspieces ( 122 ), of which one upper and one lower, which join the side elements ( 121 ) to each other, said crosspieces ( 122 ) having an inner side ( 120 ) oblique relative to a horizontal plane and inclined downwards in a front direction, wherein both of the crosspieces ( 122 ) have a triangular cross-section and wherein the shape of the cross-section of a crosspiece ( 122 ) is obtained by a rotation of 180° of the shape of the other crosspiece ( 122 ).
2. The device ( 1 ) according to claim 1 , wherein both the crosspieces ( 122 ) have oblique inner sides ( 120 ).
3. The device ( 1 ) according to claim 2 , wherein the oblique inner sides ( 120 ) form with inner sides ( 120 ) of said lateral side elements ( 121 ) one or more free passages (L).
4. The device ( 1 ) according to claim 3 , wherein the inner sides ( 120 ) of the two crosspieces ( 122 ) are parallel to each other.
5. The device ( 1 ) according to claim 4 , wherein the triangular cross-section is that of a right-angled triangle and that said oblique inner side ( 120 ) constitutes the hypotenuse.
6. A telehandler ( 100 ) whose operating arm ( 101 ) is connected to an attachment device ( 1 ) according to claim 1 .
7. The telehandler ( 100 ) according to claim 6 , wherein both the crosspieces ( 122 ) have oblique inner sides ( 120 );
wherein the oblique inner sides ( 120 ) form with inner sides ( 120 ) of said lateral side elements ( 121 ) one or more free passages (L);
the telehandler ( 100 ) being equipped with a driving position for an operator (U),
wherein in one or more positions of use of the attachment device ( 1 ) which can be moved by the operating arm ( 101 ), the direction of view (W) of the operator (U) who is in said driving position freely passes through said free passage (L).
