A trailer hitch assembly includes a receiver portion including a cylindrically-shaped cavity, a bushing member received within the cavity of the receiver portion, and a hitch member that includes a shaft pivotally received within the bushing member. At least a selected one of the bushing member and the shaft is constructed of a material that substantially eliminates the need for using a separately applied lubricant during use of the trailer hitch assembly. The hitch member also includes a first jaw member, a second jaw member coupled to the first jaw member and operable between open and closed positions, a primary latch coupled with the second jaw member and operable between a locked position preventing opening of the second jaw member, and an unlocked position allowing opening of the second jaw member, and a secondary latch coupled with the primary latch and operable between a locked position preventing unlocking of the primary latch, and an unlocked position, wherein the primary latch may be moved to the unlocked position thereof.

A toepiece (10) for a binding device for securing a boot to a gliding board comprises a fixed part (11) which is intended to be secured to the gliding board, and a mobile part (12) which is mounted on the fixed part with a possibility of relative movement (T) with at least one transverse component and on which two jaws (13d, 13g) are mounted so as to pivot about a substantially longitudinal axis (Ag, Ad). The toepiece (10) comprises a lever (16) that is actuable from the outside of the toepiece (10) and takes up a blocking position in which blocking elements (25d, 25g) that are integral with the lever (16) prevent the jaws (13d, 13g) from tilting so as to keep the toepiece (10) in a closed configuration in which the jaws (13d, 13g) retain the boot.

An assembly for fastening a transportation device of a cableway system, such as a cabin or a chair, on a suspension bar, which is formed at its upper end with a running mechanism, with a coupling clamp, interacting with the conveying cable or traction cable of the cableway system, and with a guide roller, the transportation device also being provided at its upper end with a supporting device, by way of which it is articulated on the lower end of the suspension bar in a way allowing it to be pivoted transversely with respect to the conveying cable or traction cable. The articulation of the transportation device on the lower end of the suspension bar is formed by two links, which are located at a distance from each other transversely in relation to the conveying cable or traction cable and run obliquely upward in relation to each other, their free ends being articulated on the one hand on the supporting device and on the other hand on the lower end of the suspension bar.

A support assembly (62) for an output shaft (20) of a jigsaw is disclosed. The support assembly (62) comprises a support housing (64), a lower bearing (102) arranged in the support housing and adapted to support an output shaft (20) of the jigsaw for reciprocating movement of the output shaft along a first axis relative to the lower bearing and to substantially prevent movement of the output shaft (20) relative to the lower bearing (102) in a direction transverse to the first axis, and a blade support roller (110) adapted to abut a jigsaw blade (18). A support arm 108 supporting the blade support roller (110) is adapted to pivot to a limited extent relative to the lower bearing (102) about at least one second axis transverse to the first axis to minimise the extent to which a force applied by the jigsaw blade (18) to the blade support roller (110) during cutting action causes the lower bearing (102) to apply a turning moment to the output shaft (20) about an axis transverse to the first axis.

The invention relates to an electromechanical servo steering system with an electric servo motor having a motor shaft that drives a shaft meshing with a helical gear (12), wherein the shaft is arranged in a gearbox (14) and the shaft is located in the motor The adjacent end is mounted rotatably about an axis of rotation (100) in a bearing arrangement (13), and the shaft is mounted rotatably about a pivot axis (22) perpendicular to the axis of rotation (100) in a gearbox (14). ) pivots and is provided with at least one spring element (23) that axially prestresses the bearing element (19) of the bearing device (13) that can pivot with the shaft (10) around the pivot axis (22), The bearing element (19) of the bearing arrangement (13) rests in a spring-elastic manner against the bearing element (21) of the bearing arrangement (13) which is arranged in a fixed position in the gearbox (14), wherein the bearing Exactly two spring elements (23) are arranged opposite one another in the circumferential direction of the device (13).

The invention relates to a crane having a tower (11) and a jib (9), wherein the jib (9) lies against the tower (11) in an idle position of the crane and is fixed to the tower.

A fastening system for fastening a timepiece movement in a watch case. The invention relates to a fastening system for fastening a timepiece movement (2) of a substantially circular shape in a case (20), comprising a case collar (1) in which said timepiece movement (2) is arranged, the case collar (1) extending between an upper part and a lower part, the timepiece movement (2) is fastened in the lower part of the case collar (1) using first and second fastening means provided at two opposite ends of the diameter (D) of the timepiece movement (2), at least third fastening means being angularly offset and fastened in the upper part of the case collar (1) with respect to the first and second fastening means, this allows the timepiece movement (2) to be blocked in the case collar (1).

The present invention provides an accessory for a percussion instrument, which is detachably installed relative to the percussion instrument. The percussion instrument includes: a cylindrical main body part with one side open; a hoop covering the periphery of the top; a plurality of tension bolts imparting tension to the top via the hoop; and a plurality of lugs for threading the tension bolts and provided on the main body; The accessory for a percussion instrument includes: a body part having a struck part to be struck by a player; a protruding part protruding from one side surface of the body part and being formed so as to be locked by the tension bolt; part, which protrudes from one side of the main body in the vicinity of the protruding part, and controls the percussion instrument in a state where the protruding part is locked with the hoop by one of the tension bolts. supporting, thereby limiting displacement of the body portion.

The invention discloses a piston-type integrated device for fertilizing, spraying and irrigating farmland suitable for mountains and hills. The lower part of the outrigger is covered with a sleeve, and the sleeve is detachably connected to the adjustment hole on the outrigger through an insert rod; one end of the crankshaft is connected to the There is a first rotating shaft, and the lower part of the connecting cylinder is provided with a discharge cylinder; the top plate is provided with an ejector rod corresponding to the position of the feeding hole; the driving rod is arranged eccentrically with the turntable, and the second rotating shaft is arranged on the upper side of the turntable; the upper part of the rotor moves in the circumferential direction A plurality of second connecting rods are installed on the ground, and a piston is movably installed at one end of the second connecting rods; the upper part of the cylinder body is connected with the liquid storage cylinder through the liquid inlet pipe, and the nozzle is connected with the lower part of the cylinder body through the liquid outlet pipe.
