ABSTRACT:

FIELD OF THE INVENTION
Our present invention relates to a waste receptacle composed of a synthetic resin and of the type wherein an upper formation on the front of the container is engageable by a container lifter and a grip is provided below this formation.
BACKGROUND OF THE INVENTION
Waste receptacles, especially for urban refuse removal, have of late been composed of synthetic resin material and can have, on the front of the container, a formation which is engaged by a container lifter of a vehicle into which that container can be dumped.
Below the formation, a grip may be formed from the synthetic resin material of the front wall and can be engaged during the dumping of the container to stabilize it and prevent tilting of the container in an undesired manner. For example, the container lifter or the vehicle may be provided with a lock which can engage the grip. The grip is usually provided so that it bridges two portions of the front wall of the container and itself can have inner and outer walls which are interconnected at their top and by webs between the inner and outer wall portions.
Waste containers of this type have a tendency for the grip to break away after significant usage. Essentially the grip tears loose at its ends so that the container becomes unusable.
OBJECTS OF THE INVENTION
It is, therefore, the principal object of the present invention to provide a waste container, refuse container or garbage or trash receptacle of the aforedescribed type which has a grip of improved stability and more reliable attachment to the front of the wall of the container without increasing the amount of material used.
Another object of this invention is to provide an improved waste container of the type described which is free from the tendency of the grip to tear loose from the container.
Still another object of the invention is to provide an improved container for the purposes described which is free from the drawbacks of earlier systems.
SUMMARY OF THE INVENTION
These objects and others which will become apparent hereinafter are attained, in accordance with the invention, in a waste container composed of a synthetic resin material and comprising front, rear and side walls and a bottom, the front wall being provided with an upper formation for engagement by a container lifter for dumping of the container and with a grip below the formation, the grip being elongated and defining a grip space with the front wall, the grip being formed from the synthetic resin material with inner and outer wall portions interconnected at an upper side of the grip and by spaced apart vertical webs, the inner wall portion of the grip having extensions at opposite ends defining small sides of the grip space.
More specifically, the objects set out above are achieved by providing the inner wall of the grip which is proximal to the interior of the container with extensions at both of its ends forming at least the small sides of the space defined between the grip and the front wall
With such a transition between the inner wall portion of the grip and the front wall of the container formed by the extensions which define the small sides of the grip space, an optimum force distribution is obtained at the grip and a more reliable retention of the grip on the remainder of the container. In the region of the grip ends the material no longer has a tendency to tear and thus the resulting grip construction has greater stability without requiring metallic reinforcement of the high stress regions of the grip.
An especially reliable attachment of the grip is obtained when the grip bridges a recess formed on the front outer wall of the container and the extensions are formed on or merge with the back wall portion of the recess. Stability is still further enhanced when the extensions are of arcuate configuration and especially parts of a circle, are or semicircular configuration.
An especially advantageous construction is obtained when the extensions merge with a wall parallel to the back wall of the recess and which is formed on the back wall. The parallel wall can be spaced from the back wall. The inner wall portion of the grip can thus form a closed oval which, in turn, provides especially high stability.
It has been found to be advantageous to space the inner wall extensions from the side wall portions of the recess and to bridge the gap between the two by vertical ribs. It is also advantageous to configure the space, hereinafter the grip space, so that it is oval and has a length greater than its width.
