Description

ROLLING TECHNICAL FIELD

The present invention relates to logistics equipment. In particular, the invention relates to rollable substrates, such as rollers. More particularly, the invention relates to a roller compartment according to the preamble of claim 1.

BACKGROUND

A number of different rollers for carrying articles are known in the art. The rollers typically comprise at least two vertically extending sidewalls arranged on a wheeled platform. The distance between the side walls determines the width of the roller compartment. To minimize the outer dimensions of an empty roller coaster in return logistics, it is common to arrange the roller board base to be folded to draw side walls close together. One commonly known foldable roller type is the so-called Z-tray roller, which looks like the letter Z when viewed from above. The Z-shaped arms of the platform are articulated relative to one another so that the side walls can be brought closer to each other for return logistics. In the folded state, the walls are parallel but deflected sideways, i.e. not aligned. The purpose of the sidewall deflection is to overlap the wheels of the substrate to minimize the width of the roller compartment. The space savings achieved with such roller blinds are thus based on a reduced width, however, increasing the roller length by deflection of adjacent walls. In other words, the footprint of the cabinet is significantly reduced in one horizontal dimension and slightly increased in the other cartesian horizontal dimension.

Indeed, more space-saving rollers have been developed to reduce the footprint in the folded state. Such roller compartments comprise a foldable base having a symmetrical scissor mechanism which brings the side walls of the roller into alignment. The scissor mechanism comprises two folding mechanisms arranged at each open end of the roll. Although spatially efficient, such folding mechanisms are subject to heavy use and receive shocks from the top and bottom, for example, from a fork lift fork. Thus, there is a need for a foldable roller bag that is durable enough to withstand external shocks to the foldable substrate.

SUMMARY OF THE INVENTION

A spatially efficient and robust roller housing is provided, having a first sidewall, a second sidewall, and an articulated base connecting the first sidewall to the second sidewall. The platform is adapted to guide the sidewalls between the remote position for operating the roller and the close position for the folded space of the roller through an intermediate space thus provided. The folding base has a folding mechanism having two arms hinged to the ends of the side walls with an angled hinge. The folding mechanism also has a central hinge connecting the first arms to each other in the direction of the vertical axis of rotation. In order to protect the center hinge from external impacts, each arm comprises a portion within the center hinge area narrowed in the direction of the axis of rotation.

More particularly, the roller compartment of the present invention is defined by the security requirements and is characterized in the security part of the security claim.

The novel design provides significant advantages. The center hinge, when positioned in the narrowed portion, is protected by the higher arms around the folding mechanism

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

DESCRIPTION

Fig. 1 shows a roller case 100 according to one embodiment in operating mode. In this state, the first side wall 110 and the second side wall 120 of the roller compartment 100 are in the furthest position, that is, in the farthest position. The sidewalls 110, 120 are conventional roller coaster walls having a frame made of vertical and horizontal beams that frame a net made of vertical and horizontal mesh yarns.

In the mode of operation of the roller compartment 100, the bottom (which has been omitted for illustration purposes) extends between the side walls. The bottom is hinged to the side wall, especially the first side wall. The sole is locked in a substantially horizontal operating position by various features. First, the opposite end of the base hinged end, i.e. the distal end opposite the hinged end, comprises claw-like members arranged to be suspended from a horizontal mesh of a sidewall, in particular a second sidewall. Second, the base comprises a flange portion resting against the base of the roller compartment 100.

The base is pivotable and connects the first side wall 110 with the second side wall 120 to control the side walls 110, 120 between the far position for the operating mode and the close position for the folded space (not shown) via an intermediate space thus (not shown). In the mode of operation of FIG. 1, the substrate extends in a retracted state where all components of the substrate are aligned.

FIGS. 2 and 3 show the substrate mechanics in more detail. The base of the roller 100 comprises a folding mechanism 130 at each end of the roller 100; one folding mechanism 130 is provided at one end of the roller for connecting the first and second side walls 110, 120, and another folding mechanism 140 is provided at the other end of the roller 100 for connecting the first and second side walls 110, 120. The two folding mechanisms 130, 140 are similar but arranged to mirror each other relative to the centerline of the center line connecting the first and second side walls 110, 120 of the roll. Thus, for the sake of brevity, the details of the folding mechanism will only be discussed with reference to the folding mechanism 130, which is shown in greater detail in FIG. 1.

The folding mechanism 130 is assembled to the wheels 150, more particularly to the wheel body plates, at the corners of the roller 100. The sidewalls 110, 120 are also mounted on the wheels 150, so that there is no need, for example, for a conventional A-frame. The folding mechanism 130 comprises a first arm 131 which is pivotally connected to the first side wall 110 via a first angled hinge 134 disposed at this side end. The folding mechanism 130 also comprises a second arm 132 which is pivotally connected to the second side wall 120 via a second angled hinge 135 which is mated to this side end. The folding mechanism 130 further comprises a center hinge 133 connecting the first arm 131 to the second arm 132 at a distance from the first and second corner hinges 134, 135. With the center hinge 133 centered, the first and second corner hinges 134, 135 are aligned in each state of roller 100. Thus, the central hinges 133, 143 of the folding mechanisms 130, 140 are aligned with the angular hinges 134, 135, 144, 145 in the operating mode of the roller 100 and deflected inwardly in the intermediate and folded state of the roller 100.

The first arm 131 of the folding mechanism extends past the summer hinge 133 to extend against the second arm 132 when roller 100 is in operating condition. The first arm 131 is thus longer than the second arm 132. This limits 130 movements of the folding mechanism to prevent the folding mechanism from "slipping" out. The elongated first arm 131 also cooperates with the base when transitioning from the folded state to the operating state, i.e., between them. In other words, the sole extends the scissor mechanism 130 during said movement. The sidewall of the base is shaped to engage the opposite and elongated first arms of the folding mechanism 130 in the intermediate space to guide the base toward the operating mode of the roller 100, i.e., to correct the scissor mechanism 130.

The angular movement of the folding mechanism 130 is achieved by the hinges 133-135.

Corner hinges 134, 135 and corresponding arms 131, 132 include a stop mechanism for restricting movement of the arms to prevent the center hinges 133, 143 from moving past the line connecting the corner hinges 134, 135 to the outside of the roller 100. At least one of the angular hinges 134, 135, but preferably both angular hinges of the folding mechanism 130 comprises / comprise an angled lug 136, 137 for receiving the end of the arm 131, 132. The lug 136, 137 is welded or otherwise connected at an angle between the wheel frame plate and the frame of the side wall 120. The corner lug 136, 137 and the arm 131, 132 each comprise openings which are aligned to receive the connecting hinge mandrel. The arms 131, 132 also comprise a stopper designed to engage the bracket 136, 137 for defining the pivotal movement of the arm 131, 132 about a horizontal axis formed by the hinge mandrel.

FIG. 3 shows a specific feature of the present roller compartment 100. As will be seen, the central hinge 133 is disposed centrally at a distance from the first and second side walls 110, 120. That is, the center hinge 133 connects the first arm 131 to the second arm 132 at a distance from the first and second corner hinges 134, 135. The area in which the center hinge 133 is provided is narrowed in height to protect the center hinge 133 from external shocks. That is, the first and second arms 131, 132 each comprise a portion within the region of the center hinge 133 which is tapered in the direction of the axis of rotation provided by the center hinge 133. One way of dimensioning the embedded hinge portion of the folding mechanism 130 is to follow the tapered arm portions which are recessed so that the center hinge 133 does not extend past the imaginary extensions of the higher arm portions (shown by dashed lines) in the direction of the axis of rotation. More specifically, the arms 131, 132 are connected to the side walls 110, 120 by the higher portions and the tapered shaft portions. The first arm 131 of the folding mechanism 130 extends past the center hinge 133 to extend against the second arm 132 when the roller 100 is in the operating position. The first arm 131 is thus longer than the second arm 132. This limits 130 movements of the folding mechanism to prevent this "collapse".
