Abstract
A plate-shaped element (1), for example a lid for an upwardly open container. The element has through openings (2), through which cup-shaped elements (5, 6) extend. The cup-shaped elements can, for example, form guides toward the side walls of the container in the corners between these. The cup-shaped elements consist of an upper cup (5), having a flange (7) bearing against the top side of the plate-shaped element, and a lower locking element (6), having a flange (14) bearing against the bottom side of the plate-shaped element. The cup and the locking element are fixed to each other with the aid of snap-locking members (13, 21), which are configured on the cup and the locking element and cooperate with each other and which are characterized in that they are situated at a substantial distance from the edge of the associated opening, thereby resulting in a long deformation section between the snap-locking members (13, 21) and said upper and lower flanges (7, 14).
Description
The present invention relates to a plate-shaped element, which has at least substantially flat, opposing upper and lower faces and at least three through openings, through which cup-shaped elements extend and jut down past said lower face, which cup-shaped elements each comprise an upper cup with an upper edge flange projecting over said upper face, a lower locking element, which surrounds a portion of the cup jutting down from said lower face and has an edge flange projecting over said lower face, and snap-locking members, which are configured on the cup and the locking element and cooperate with each other and which, in their engagement position, fix the locking element to the cup.
It is previously known to configure pallets, for example, in the above-stated manner. One example is shown and described in US-A-3 610 172. The pallet here consists of a flberboard plate-shaped platform having a number of, more precisely six, uniformly placed openings, in which plastics cup-shaped support legs of above-stated configuration are fixed. The support legs rest against the base of the pallet. The interspaces between the support legs correspond to the interspaces between the distancing blocks on a conventional pallet, into which lifting forks on a forklift truck can be introduced.
One advantage with a pallet of this configuration compared with a conventional pallet is that the pallets can be stacked one upon the other, so that the support legs on an overlying pallet can jut into the upwardly open cups, formed by the support legs, in an underlying pallet. By suitable configuration of the support legs, the pallets can then be stacked virtually without interspaces between the bottom side of an overlying pallet and the top side of an underlying pallet. The positive- locking engagement between the pallets allows the possibility of higher stacks without risk of the stack tipping over, compared with a stack of conventional pallets.
One problem is, however, to achieve a solution as regards the configuration, the production and the fixing of the cup-shaped elements on the plate-shaped element, which solution is economic and at the same time satisfies the strength requirements. In the known construction which is described above, the snap
fastening between the cup and the locking ring is localized to the region closely adjacent to the periphery of the opening. This means that there is high risk of the snap fastening becoming undone, if the plate-shaped element is made of a material which is prone to swell, for example if exposed to damp. The same applies if the cup-shaped element is exposed to mechanical action giving rise to laterally directed forces which endeavor to deform the element. This dependent on the deformation section between the bottom side of the plate-shaped element and the snap fastening being very short and therefore allowing very limited deformation before the snap fastening is actuated and is at risk of becoming undone.
The object of the present invention is generally to provide a plate-shaped element of the kind stated in the introduction which is easy and cheap to produce and install and which allows relatively large swelling of the plate-shaped element and relatively large mechanical action upon the cup-shaped element, while maintaining secure engagement between the cooperating snap-locking members of the snap fastening.
This is achieved according to the invention by means of a plate-shaped element which is characterized in that the snap-locking members are dimensioned and placed such that said engagement position lies at a substantial distance from the outer edge of the opening.
Conducted trials have shown that a particularly positive result is obtained if, according to one refinement of the invention, the snap-locking members are dimensioned and placed such that the engagement position lies closer to the center of the opening than the outer edge of the opening. This produces a long deformation section between the snap fastening and the flange connection between the plate-shaped element and the cup-shaped element.
One preferred embodiment of the plate-shaped element according to the invention is characterized in that the cup and the locking element have a circular cross-section, in that the cup has a conical, annular bottom portion, which surrounds an at least substantially cylindrical portion jutting down from the inner periphery of the conical portion, and in that one snap-locking member is formed by an external groove in the cylindrical portion. By configuring the locking
element with a slotted, weakly conical portion which surrounds the cylindrical portion of the cup and has hook elements which, in the engagement position, engage in said grooves, a secure snap fastening between the cup and the locking element is obtained, which is protected against external damage.
In one preferred embodiment of the plate-shaped element, which is especially intended for use as a lid for a rectangular or square, upwardly open container, the plate-shaped element has a shape matched to the edges of the opening of the container, and four through openings with associated cup-shaped elements positioned such that they form guides toward the side walls of the container in the corners of the container.
The invention is described in greater detail below with reference to illustrative embodiments shown in the appended drawing, in which:
fig. 1 shows an exploded view of a part of a plate-shaped element with an embodiment of a cup-shaped element according to the invention,
fig. 2 shows the elements in fig. 1 in the assembled state, and
fig. 3 shows a longitudinal section through parts of two plate-shaped elements according to the embodiment in fig. 1 and 2 stacked one upon the other.
In fig. 1 and fig. 2, a part of a plate-shaped element 1 with the dividing plane through the middle of an opening 2 is shown in perspective. The element 1 has a flat upper face 3 and a flat lower face 4, which faces are parallel. A cup, generally denoted by 5, as well as a locking element, generally denoted by 6, are shown divided in the same plane as the opening 2. The plate 1 can be a wood fiber plate, whilst the cup 5 with the locking element 6 is expediently made of a plastics material which allows a certain elastic deformation.
As can most clearly be seen from fig. 3, the cup 5 has an upper annular flange 7, which in the illustrated fitted state of the cup bears against a recessed face portion 3 a of the upper face 3, but can just as readily bear directly against the face 3 in the absence of a recess. The annular flange 7 merges into a cylindrical side portion 8, which, in turn, merges into a partially conical annular bottom portion 9.
Finally, the bottom portion 9 merges into a downwardly directed cylindrical end portion 10 having a lower end closed by a bottom 11. At the upper end of the cylindrical end portion 10, a groove 12 is configured, whose lower edge 13 forms one of two cooperating hook elements which together form the snap fastening.
As can also most clearly be seen from fig. 3, the locking element 6 has an annular flange 14, which in the illustrated fitted state of the locking element bears against the lower face 4 substantially directly opposite the upper flange 7. The annular flange 14 adjoins the lower end of a cylindrical side portion 15 accommodated in the opening 2 of the plate, which side portion, in turn, merges into a first conical, annular bottom portion 16. The inner peripheral edge of the bottom portion 16 adjoins a second cylindrical portion 17, which merges into a second conical portion 18, from whose inner periphery a weakly conical portion 19 extends upward toward the inner peripheral edge of the bottom portion 9 of the cup.
The weakly conical portion 19 of the locking element 6 surrounds the cylindrical end portion 10 of the cup 5 and, at its upper end, is configured with a flange 20, whose lower edge 21, in cooperation with the edge 13 of the groove, forms the snap fastening. As can be seen in particular from fig. 1, the portion 19 is cut up, so that tongues 19a with intervening slots 19b are formed. The tongues 19a thereby form hook elements of tailor-made resilience.
In the installation and fixing of the cup-shaped element 5, 6 in the opening 2, the cylindrical portion 15 of the locking element 6 is brought from below up into the opening 2, so that the flange 14 comes to bear against the lower face of the plate. After this, the cup 5 is brought down into the locking element 6, whereupon the above-described conical faces of the cup 5 and the locking element 6 help to center the end portion 10 of the cup against the upper end of the weakly conical portion 19 of the locking element 6. Upon the initial contact between the flange 20 on the conical portion 19 of the locking element 6 and the lower end of the cylindrical portion 10 of the cup 5, the tongues 19a are forced apart, since the internal diameter of the flange 20 is somewhat less than the outer diameter of the cylindrical end portion 10 of the cup. In order to facilitate the forcing apart, both the flange 20 and the cylindrical end portion 10 are configured with beveled face portions 22 and 23 respectively.
In the illustrated preferred illustrative embodiment, the axial extent of the weakly conical portion 19 is matched to the axial extent of the cylindrical end portion 10 of the cup 5 such that the upper end of the tongues 19a butt against the bottom portion 9 of the cup, at the same time as the annular flange 7 of the cup butts against the upper face 4 of the plate-shaped element, when also the lower edge 19 of the flange 20 snaps over the edge 13 of the groove 12 in the end portion 10 and locks the cup 5 to the locking element 6. In this position, the conical annular bottom portion 9 of the cup 5 also bears against the first conical bottom portion 16 of the locking element 6.
When a plurality of plate-shaped elements 1 are stacked one upon the other, as can be seen from fig. 3, the downwardly directed force from the loading of an overlying element 1 will be transferred to the directly underlying element 1 via the conical portion 18 of the locking element 6 of the overlying element 1 to the conical bottom portion 9 of the cup of the underlying element 1. The downwardly directed force from the cup 5 to the locking element 6 is transferred via the portion 9 of the cup 5 and the end face of the tongues 19a or the face 16 of the locking element 6.
As a result of the described embodiment, a secure locking of the conical element 5/6 on the plate 1 is achieved with a simple fitting process. The central placement of the cooperating snap-locking members 13 and 19a produces a protected placement within the cylindrical portion 17 of the locking element, which results in little risk of involuntary release of the snap-locking connection under mechanical action. An important consequence of the illustrated central placement of the snap-locking connection 13, 19a is also that it ends up at a relatively large axial and radial distance from the flanges 7 and 14 bearing against the plate, which results in a long deformation section in the event of possible mechanical action upon the cup-shaped element 5, 6. This, in turn, leads to substantially less risk of the snap-locking connection becoming undone, compared with if the snap- locking connection were placed, in a known manner, closely adjacent to the flanges 7 and 14. In the illustrated embodiment, the distance from the engagement position of the snap-locking members 13, 19a to the edge of the opening 2 is substantially longer than to the center of the opening, more precisely about three times longer.
Should a plate-shaped element 1 according to the invention be discarded, the illustrated and described embodiment makes it possible to remove the cup-shaped elements 5, 6 easily from the plate 1 by banging with a suitable tool against the bottom 11 of the cylindrical portion 10 so that the snap fastening becomes undone. This is advantageous, for example, in source-sorting of waste, where plastics products are to be separated from timber products or if a damaged cup- shaped element 5, 6 needs to be replaced.
In a refined embodiment of the invention, the snap fastening can be reinforced by being supplemented with lugs 30 (one shown) evenly distributed on the outside of the conical bottom part 9, which are disposed at such a distance from the groove 12 in the cylindrical portion 10 that a certain elastic deformation of the lugs 30 is required to allow the hook elements 19a to be introduced between the edge of the groove 12 and the lugs 30.
The invention has been described above with reference to a preferred embodiment shown in the appended drawing, but can be varied, of course, within the scope of the following patent claims. If, for example, there is no need to remove or replace a cup-shaped element 5, 6, the bottom 11 of the cylindrical portion 10 does not need to be accessible from below through the locking element 6. Depending on the application, the lugs 30 can also be omitted.
