Quays for slings

The present invention relates to hooks for slings and in particular, although not exclusively, to the so-called Sugar cane hooks i'är sugar cane loops.

The sugar cane loops are intended for loving and treating sugar cane bunches, although of course similar loops? Uca are used to treat bunches of other haterias. Line Such a loop consists of a chain with _c 'e a Hing to ^ Eden end, said .uette by means of a so-called \ ckerrchr-Lakens in "ine zuzieLbere ocLle''are each or a slip knot vervandel v / iru ν ± id this Zuciwerrohrhaicen has a body with a quick lock and a block, dui'cli \\ ^f elcLen die ^ ette läid't, v: obei äex Bloci: a blocking - ".- .. linl: c ..ntLält, ^T : elcLe of the chain allowed through the block

The known cane hooks have four main parts, each of which is pivotable between a pair of side plates is arranged and this' IOiIe a hook, the one or has two claws and a pivoting movement between a locked and a released position executes a pawl that pivots into a position and from a SUeIiUiLJi; can perform in welciier the lick cn is determined in its coupled position is a pawl which is pivotably mounted and brought into engagement with a chain carrying the hook, wherein the! Lette runs between the pawl and a pulley which forms part of the block and is mounted on a further pivot for rotation between the side plates. The mechanism is held together by riveting the heads of the trunnions which pivot the various above mentioned ones Wear parts.

The aim of the present invention is to provide a hook with a simplified and reduced construction Dimensions combined with improved strength.

The hook according to the invention: for use with a chain loop has a pivoted hook, a pawl for the hook and a chain pawl that is arranged between two side parts, which are directly connected to each other to form a block, wherein the pawl and the pawl by spring force in

engaged positions driven and on a common Trunnions are mounted. The pawl or the release pawl and the pawl are through the opposite Applied to the ends of a common flat spring.

The block also preferably does not have a chain pulley, although additional chain guides are integral with the Side parts are formed.

The invention is described below with reference to accompanying drawings described; show in it:

Fig. 1 is a perspective view of a sugar cane loop in the arbsitssustsjid, the preferred mode of use illustrates the hook according to the present invention on the one hand and according to the prior art will;

Fig. 2 is a vertical sectional view of an embodiment a hook according to the invention, wherein the internal mechanism is shown; and

Fig. 3 is a plan view of the same hook, for the sake of clarity has partially broken away.

Referring to Fig. 1, this figure shows that a cane bundle B of two chain loops - which are generally designated by the reference numeral 2 - from the hook 4 on each end of a bracket 6 are carried. The loops 2 have chains 8 which have rings 10 at each end and with the help of the cane hooks 12 in closable loops are Verwonaaolt, the function of the hook 12 on the one hand is to form a loop or knot that

The pins 30, 2 extending between the side parts 1G halo a plate lower 34 in position, one end 36 of this spring being supported against the locking pawl 26 and driving this pawl by spring force into a position in which it has a Uase 37 on Hook 28 comes into engagement which, as shown, can be provided with a single claw 38 or as in the sugar cane hooks according to the prior art with a double claw. The pawl 26 is also provided with a fork 40 which forms a .'-> .tz for the use of the lever, which can be used to release the pawl 26 from its position in which it with the nose of the hook 28 against the Pressure of the spring 3 ^ comes into engagement.

The other end of the sleeve 34 engages a pin 42 carried by the release pawl 24, the Spring seeks to bring the pin into engagement with projections 44,

While the slat can be pulled up through the gap between the surfaces 46, 4j and the projection 44, a nose ? 0 of the pawl 24 prevents downward movement of the slat. As soon as, therefore, according to i'ig. 1 a lifting force is exerted on the chains 8 by the bracket C, these are running through the loops of the hooks 12, as a result of which the loops or notes are tightened around the bundle, although the tension of the chains is released 6 does not lead to loosening of the notes. The bundle held by the notes can be instantly released by moving the pawls 26 by means of levers inserted in the forks 40

Since the pawl 26 and the inline 24 are mounted on a common pivot pin, the total length of the sheets is reduced compared to the prior art, while the omission of the disc, which is used to guide the lcfoe in the sugar cane hook according to the prior art the 'Hechx.ik is used allows this section of the hook construction to be much stronger and more compact. Additional ¹ . The fact that all of the main parts of the sheets can be manufactured as die-cast items lead to these features. Obtaining a sugar cane hook that is smaller, lighter and stronger or stronger than the hooks intended for the same purpose according to the state of the art.
