Description

Loading handle

The present invention relates to a handle of load that is curved so that it overlaps a container with which can be articulated in front and behind with its ends and which has a central handle.

Containers with cargo handles are known by practice in multiple ways. So, for cubes in which coating materials are made, in particular dyes (colloquially painting, painter color), are widely spread steel wire loading handles on the that a roller is open as a handle. Usually carry such a bucket with one hand on one side of oneself. Axes of articulation of the loading handle on the bucket are then found front and back, and the cube can swing laterally. The side convex of the loading handle that is located above during the transport is designated in what follows as the outer side, and the side Concave loading handle is designated as inner side. The handle of load is specularly symmetric with respect to its central plane longitudinal and to its central transversal plane. Therefore, the Front and back terms are interchangeable. EP 298 930 reveals a state of the art loading handle according to the preamble of claim 1.

The problem of the invention is to create a handle of ergonomically favorable load of the type mentioned at the beginning that offer high transport comfort and that can be manufactured easily and saving material, disposed of as trash without problems and more easily equipped with additional functions.

The charging handle that solves this problem presents a lattice profile that is not completely reached until the handle to ensure a torsional clearance with a defined damping.

The production of the loading handle completely from Plastic carries considerable advantages. Also, since the container is usually made of plastic, manufacturing and Assembly are completely at hand. For the loading handle you can use the same plastic as for the container. It has then before it a container of a single material that is easy to Discard as trash. With the lattice profile that reinforces the handle loading saves material and achieves high rigidity. Given the the lattice profile does not extend completely to the handle, it is guaranteed an elastic torsion clearance at the start of the support arms, whose damping can be adjusted so defined, so that the container is decoupled from the wrist of the person who carries it in regards to vibrations. Further, result in reduced body load and transport comfort improved

In a preferred embodiment, the handle is hollow, is open on the outside and is reinforced with some nerves. This saves material.

In a preferred embodiment, the handle has a central nerve and transverse nerves that they extend perpendicularly to it.

In a preferred embodiment, the handle has side walls that protrude laterally in cantilever with a convex bulge with respect to the arms of support, an inner wall protruding from the support arms with a convex bulge inward and transverse walls in the extremes

In a preferred embodiment, the handle widens from inside to outside and narrows from the zenith of the loading handle forward and backward. This is especially favorable from the ergonomic point of view.

In a preferred embodiment the handle is flat on the outside Therefore, the nerves that serve to reinforce handle does not sink into the hand.

In a preferred embodiment, the support arms have a double T lattice profile with a central soul, lower and outer bands that come out transversely from it and oblique struts between them that apply to the central soul.

In a preferred embodiment, the struts extend in zigzag. Form triangular compartments

In a preferred embodiment, the support arm bands are applied to the walls transverse of the handle, so that they end flush with the inner wall, side walls and the outer side of the handle. Extreme struts of the support arms are opposite to the transverse walls some distance from them. Preferably, the end struts extend transversely to the bands of the support arms.

In a preferred embodiment, the ends of the support arms are reinforced between the bands and are provided with tree pivots protruding from the band inside. The lattice profile does not extend completely until the reinforcement. This is not necessary, since the ends of the arms of support are loaded substantially only to traction. He reinforcement enables precise sizing of elasticity spring that is necessary for placing the loading handle in the recipient.

In a preferred embodiment, the handle of load is provided with a mechanism to lift the lid of the container.

The invention is explained below with more detail using an example of embodiment represented in the drawing, in which:

Figure 1 shows the perspective view of a loading handle;

Figure 2 shows a side elevation of the handle of load;

Figure 3 shows an exterior view of the handle of load looking in the direction III of figure 2;

Figure 4 shows an inside view of the handle of load looking in the direction IV of figure 3;

Figure 5 shows a front elevation of the handle of load looking in the direction V of figure 3;

Figure 6 shows a section through the end of the loading handle according to VI-VI of Figure 2; Y

Figure 7 and Figure 8 show some sections through the handle of the loading handle according to VII-VII and VIII-VIII of the figure 2.

The loading handle is a cast whole piece by plastic injection. It extends over a circle arc of slightly more than 180º and is radially tucked and flattened with respect to this one at the zenith. The zenith part of the loading handle forms a handle. The parts of the load handle that apply to the handle in front and behind in prolongation of it designate in the following as support arms. The loading handle is specularly symmetric with respect to a central plane longitudinal parallel to the plane of the drawing of figure 2 and a central transverse plane perpendicular to it.

The handle has an open housing towards the convex outer side of the load handle with a cross section semi-washed The housing is delimited by means of an inner wall 10, side walls 12 and transverse walls 14. It has its maximum width at the zenith of the loading handle. The housing widens from inside to outside and narrows from the zenith forward and backward. The inner wall 10 of the housing is domed in convex inward shape. The side walls 12 of the housing they leave laterally in cantilever with a convex bulge. The Housing is flat on the outside.

The handle housing is reinforced with nerves 16, 18 that occupy the entire height of the interior of the Case. A central nerve 16 that is in the central plane length of the loading handle is connected in one piece with the wall interior 10 and the transverse walls 14 of the housing. Perpendicular to the central nerve 16, some nerves extend equidistant cross-sections 18 that are joined in one piece with the central nerve 16, the inner wall 10 and a side wall 12 of the Case. A central transverse nerve 18 is in the central plane transverse loading handle.

The support arms are applied to the walls transverse 14 of the handle. They have a double T profile with a central core 20 that is in the longitudinal central plane of the handle loading The double T profile has inner bands and exteriors 22, 24 that protrude from the central soul 20 and which end flush with the inner wall 10, the side walls 12 and the outer side of the handle.

The support arms are reinforced with struts 26 that are applied forming a piece to the central core 20 and bands 22, 24 and extend obliquely between bands 22, 24. The struts 26 form a lattice. They have a path in zig Zag. The struts 26 separate compartments triangular

The double T lattice profile does not extend completely to the handle. In front of the walls transverse 14 of the handle is arranged, to a certain distance, a respective end strut 28 extending transversely to bands 22, 24 of the support arms. By therefore, the support arms are less rigid at their point of start. They can be warped (twisted) more easily, so that the cube is disengaged from the wrist of a person wearing it which concerns the vibrations. Thanks to the elasticity of plastic material and to the geometry of the loading handle are guaranteed a restoring force and a damping of the Torsion perfectly defined.

At the ends of the support arms are conformed tree pivots 30 protruding from the band inside 22 inwards. Tree pivots 30 are diametrically opposed to each other on the same axis.

The support arms are reinforced to the height of shaft pivots 30 between bands 22, 24 with two parallel souls 32 that extend transversely to the bands 22, 24. The double T lattice profile does not extend completely until reinforcement.
