SE500041C2 - Handles for garbage containers, containers or similar - Google Patents

Abstract

Handle (1) constituting an integrated part of a waste, transport or storage container or the like (2) made of plastic material. The handle (1) comprises two principally vertically arranged beams or the like (3, 4) which preferably at their lower ends (5, 6) are connected by means of a third beam or the like (9) representing the grip of the handle (1). The third connecting beam (9) of the handle (1) is provided with principally vertically arranged internal reinforcing substantially discoid profiles (12), arranged at an interval of 5-10mm, and lacks on the base (19) and on the lower part of the side (10) facing the container (2) external wall (20). The side (10) of the third connecting beam (9) has a curved slope of 10-30 DEG to the vertical plane.

Description

SJJ 041 1 grip profiles.

The technical advantages of stiffening slats as above are that they allow the third beam, the grip of the handle, to have a design which means different widths on its upper and lower part and a rounded inclination of its side facing the vessel, whereby an angle relative to vertical the plane of 10-30 °, preferably 15-25 °, is obtained. An embodiment where the side of the grip facing the vessel at the top is wider than at the bottom is adapted to the hand and its fingers. The described design of the grip can not be carried out by injection molding with an entire outer wall with an even and continuous material thickness without undercutting being obtained during the injection molding. In that case, the wall thickness must be markedly increased, which results in an extended process cycle with problems in e.g. cooling of the injection molded material. Because the underside and the lower part of the side of the grip facing the vessel lack an outer wall as described above, the design described can be obtained by injection molding without sacrificing e.g. manufacturing conditions, stability and / or ergonomics do not need to be made, nor are special injection molding equipment required.

Stiffening slats / grip profiles as above, which are not covered by an outer wall, means that in addition to the advantages described above, the hand and fingers also receive a better grip. If the lamella profiles are placed with an interval of 5-10 mm, preferably 6-8 mm, the best feeling is obtained when these are gripped.

In a preferred embodiment, the two vertically arranged beams of the handle are of different lengths and the third beam of the handle, the grip, is inclined at an angle relative to the horizontal plane of 5-45 °, preferably 10-20 °. By allowing the handle's grip to tilt in relation to the horizontal plane, an ergonomically correct hand position can be obtained. The natural position of the hand when, for example, a rubbish bin or other wheeled container, etc. 3 »500 041 is pushed or pulled is not horizontal.

It is convenient to apply at least two handles in pairs, preferably on the short sides of the vessel and adjacent to its upper rim.

From an ergonomic point of view, the shorter of the handles' vertically arranged beams are preferably facing each other so that the grips of the handles are angled upwards towards each other.

The invention is further explained in connection with the accompanying figures, of which - Figure 1 shows in plan view an embodiment of a handle according to the invention. The handle is fitted with stiffening slats / grip profiles and is shown from a side facing a vessel.

Figure 2 shows in plan view a container type of rubbish bin seen from one side of the card. The vessel is provided with two handles according to an embodiment of the invention.

Figure 3 shows in section a side view of an embodiment of a grip for a handle according to the invention.

Figure 4 shows in section a side view which illustrates how much the wall thickness of the grip must be increased on a handle with the same design as figure 3, starting from an entire outer wall with an even and continuous material thickness.

Figure 1 shows an embodiment of a handle 1 (Fig. 2) from a side facing a vessel 2 (Fig. 2), which side 10 (Fig. 3) constitutes the inside of the handle 1. The handle 1 consists of two vertically arranged beams 3,4 and a third beam 9 which 5: 0 041 7 connects the beams 3 and 4 and thereby constitutes a grip to the handle 1 grip. Furthermore, the handle 1 is provided with stiffening internal lamella profiles 12, which on the lower part 11 of the inside 10 of the grip and on the underside 19 of the grip are not covered by any outer wall 20 (Fig. 3). The beam / grip 9 is inclined at an angle 13 (Fig. 2) of 15 ° relative to the horizontal plane.

Figure 2 shows from a short side a wheeled container 2, of the type of rubbish bin, which is provided with two handles 1 according to the same embodiment as figure 1.

Figure 3 shows in section a side view of an embodiment of a beam / grip 9 (Figs. 1 and 2) of a handle 1 (Fig. 2) according to the invention. The beam / grip 9 is wider at its upper 18 (fig. 1) than at its lower 11 (fig. 1) part. The outer wall 20 of the beam / grip 9 does not cover the underside 19 of the grip or the lower part 11 of the side facing the vessel 2 (Fig. 2). In this case, the beam / grip 9 can be manufactured by injection molding without obtaining undercutting and without requiring special equipment.

Figure 4 shows in cross section a beam / grip for a handle with the same design as that shown in figure 3, but with an inside 15 with a whole outer wall with even and continuous material thickness 16. The material thickness 16 of the inside 15 must be increased, which is marked by a portion 17, to be manufactured by injection molding without undercutting. The thereby increased total material thickness will lead to manufacturing problems e.g. when cooling injection molded material.

The invention is not limited to the embodiments shown as these can be varied within the scope of the invention
