Abstract

A crate for a concrete mixer comprises four posts (1) connected by struts (2) and foot battens (3), a centering batten (4) being secured parallel to a batten (3) and at the outer side of one pair of posts (1) at such a height (h) that the centering batten (4) projects into a space between a locking plate (8), a yoke bearing arm (9) and the upper end of a frame post (7) of the thereby immovably securing the mixer in the crate. A further patten (6, Fig. 1, not shown) protects a motor canopy (14) of the mixer, which rests upon the foot battens (3). <IMAGE>

Description

SPECIFICATION Packing and transportation container for concrete mixers Technical Field Of The Invention The invention relates to a packing and transportation container for concrete mixers. It is to be understood that the type of concrete mixer with which the present invention is concerned is one in which a mixing drum is mounted in bearings in a U-shaped yoke and carried in a framework provided with pedestals, which can be designed to be removable or foldable.

Background Art Formerly such concrete mixers were delivered in an unpacked condition or in cartons.

In the latter case it was necessary for any components projecting outside the concrete mixer framework, for example a driving motor with the motor canopy, the support legs, and the like, to be delivered in a disassembled condition apart from the package, which obliged the consignee himself to carry out the assembly work. The despatch of a part or parts in the unpackaged condition involves the risk of damage in transport.

The present invention takes as its basic purpose the development of a packaging and transportation container for concrete mixers, which offers the possibility of packing and delivering the concrete mixer in the assembled condition, but with the legs folded away, and which ensures secure postioning of the concrete mixer in the packaged condition at a low capital cost.

Disclosure Of The Invention The invention is characterized by a batten crate including four posts mutually braced together, and which are connected together in pairs by foot battens at the base, whilst an additional centering batten, extending parallel to the foot battens, is secured at the outer side of one pair of posts at such a height that it is situated in the free U-shaped space defined between the locking plate, the yoke bearing arm and the upper end of a frame post of the concrete mixer.

Within the scope of the construction the height of the centering batten above the foot battens is arranged to correspond to the height of a concrete mixer after the support legs thereof have been swung inwardly. Moreover the pairs of posts may be connected together at their upper ends, in a direction transverse to the direction of the foot battens, by cross battens, which project at one end beyond the posts and are connected at that end by a connecting batten serving to protect the motor canopy of the concrete mixer situated below it.

The adoption of such a construction of crate offers the possibility of packing a contrete mixer of conventional construction in the already assembled condition, at a minimum of capital cost, and, if required, with the legs folded away, but still connected to the framework of the mixer, whilst the provision of the centering batten offers the special advantage that the packaged concrete mixer is so securely fixed in position that during transportation it is not subjected to any displacement relative to the crate.

A practical example of the invention is illustrated schematically by way of example in the accompanying drawings.

Brief Description Of The Drawings Figure 1 is a perspective view of a crate, Figure 2 is a side elevation of the crate according to Fig. 1 with the concrete mixer inserted therein, and Figure 3 is a front elevation of the crate according to Fig. 1 with the concrete mixer inserted therein.

Best Mode For Carrying Out The Invention The crate shown in Fig. 1 comprises four posts 1 which are connected in pairs at their upper ends by top battens 1 6 and at their lower ends by foot battens 3, and are also interconnected by bracing struts 2. At their upper ends, and transverse to the direction of the battens 3, 16, there are provided cross battens 5, which project at one end beyond the pair of posts 1 and are joined together by a connecting batten 6.

At the side remote from this connecting batten 6 there is secured a centering batten 4, which is fixed to the outer side of the posts at a definite height h above foot batten 3. The definition of this height h is derived from Figs.

2 and 3.

Figs. 2 and 3 show in different views the batten crate with the concrete mixer inserted therein. It is seen that the mixing drum 10, with its framework posts 7, rests upon the foot battens 3 and that the legs 12, 1 7 are in the folded away condition but still connected with the framework 7 of the mixer. 1 3 indicates schematically the road wheels. The manner in which the legs 12, 1 7 are arranged is the subject matter of another invention. At the upper end of a framework post 7 of the mixer there are arranged in conventional manner the locking plate 8 and the support arm 9 of the U-shaped bearing yoke for accommodating the mixing drum 10. The conventional hand lever is indicated by 11.

Between the locking plate 8 and the bearing arm 9 there remains a U-shaped space, which is necessarily the result of the conventional construction of concrete mixers, and which is bounded at the lower side by the upper end of the framework post 7. The centering batten 4 projects through this Ushaped space (compare also Fig. 1) whereby the centering of the concrete mixer is achieved in the horizontal and verical directions of the crate. Accordingly during transportation the concrete mixer cannot be subjected to any independant movement within the crate.

From these conditions the height h according to Fig. 1 is determined. The centering batten 4 can, after the concrete mixer has already been inserted in the crate, be fixed to the posts 1, for example by nailing. By this method it is possible to pack in the same type of crate mixers having different constructional heights.

Claims

1. A packing and transportation container for a concrete mixer, characterized by a crate made of battens, including four posts (1) braced together and connected in pairs at their lower ends by foot battens (3) wherein there is provided at the outer side of one pair of posts (1) a centering batten (4), which extends parallel to the foot battens (3) at such a height (h) that the centering batten is situated in the free U-shaped space between the locking plate (8), the bearing arm (9) and the upper end of a framework post (7) of the concrete mixer.

2. A container according to claim 1, characterized in that the height (h) of the centering batten (4) above the foot batten (3) is dimensioned to correspond to the height of a concrete mixer after the legs (12, 17) have been swung inwardly.

3. A container according to claim 1, characterized in that the posts (1) have their upper ends connected in pairs by cross battens (5), which extend transverse to the direction of the foot battens (3) and which project at one end beyond the posts (1) and are connected together at that end by means of a connecting batten (6) for the purpose of protecting the motor canopy (14) of the concrete mixer situated underneath.

4. A packaging and transportation container for a concrete mixer substantially as hereinbefore described with reference to the accompanying drawigns.
