The present invention relates to a folding table, and more particularly to a folding table that is able to be rolled along the floor.
It is desirable in large venues, such as conference centres, hotels and meeting halls, for tables to be able to be brought out from storage and arranged for a particular event, taking into consideration the number of people and the needs of the event.
For this reason, a number of different folding table configurations have been developed. The most common folding table has metal legs that are hinged to the underside of a table top. The legs fold underneath the table top and the folded tables are carried and stacked for storage.
Another type of foldable table has an underlying frame that includes wheels to allow rolling of the table. The table top may have a central split line that is hinged, so that the table top folds down around the frame to reduce with allowing tables to be stored next to each other in a smaller space. However, these types of tables still take up a large amount of storage space, as it is only as small as the width of the frame and wheel assembly.
There are other types where the frame may also hinge allowing the width to be reduced. However, these arrangements present a very undesirable visual presence, requiring the tables to be covered with a tablecloth to conceal the split line. The split line also can cause unevenness in the top surface if the two halves no longer align correctly.
Another known solution is to provide wheels on the underside of the table top. When the legs are folded underneath, the table can be tilted slightly and the table can be rolled to storage. However, this can compromise visual appearance as the wheels are exposed during use. They can also compromise storage, as they project perpendicularly from the table top under surface, increasing the depth of the folded table.
It is therefore desirable to provide a foldable table that offers an alternative to the current systems.
Reference to any prior art in the specification is not an acknowledgment or suggestion that this prior art forms part of the common general knowledge in any jurisdiction or that this prior art could reasonably be expected to be understood, regarded as relevant, and/or combined with other pieces of prior art by a skilled person in the art.
Accordingly, the present invention provides a folding table, including:
a table top having a top surface and a bottom surface;
two opposing legs at or adjacent respective opposing ends of the table top; the legs being movable between an unfolded position for supporting the table top above a floor surface, and a folded position whereby the legs lie underneath the bottom surface;
at least one roller device located towards an end of the table top;
whereby in the unfolded position the roller is concealed behind the table top and leg, and in the folded position the roller is exposed to the end of the table top to allow rolling of the table in a tilted orientation along a floor surface.
The top surface of the table top is preferably generally planar. The legs are preferably panels extending in width the same as the depth of the table top and may have an exterior that is generally planar. The table top and leg may meet at a mitre joint. It will appreciated that alternative joints may be utilised.
The underside of the table top at one or both ends has cut out portions. The upper ends of the respective leg or legs have cut out portions. The cut out portions preferably do not extend the full width of the table top, such they are not visible from the sides or ends. The cut out portions may correspond to form a pocket on the inside of the corner when in the unfolded position. The pocket may be sized to receive a roller device. There may be: a single roller device at only one end; a single roller device at each end; multiple roller devices at one end; or multiple roller devices at each end.
The legs and table top are preferably connected by a standard corner hinge connection, having a first bracket on the table top and a second bracket on the leg, with a central pivot. The roller device may be connected to a scissor link hinge. The ends of the arms at one end being commonly connected to the roller device, and the ends of the arms at the other end being split and respectively attached to the corner hinge first and second brackets. As the leg is folded, the scissor link hinge extends the roller outwardly from and between the table top end and the upper end of the leg. As the leg is unfolded, the brackets move apart, drawing the ends of the scissor arms outwards and drawing the roller device inwards to sit within the pocket.
Advantageously, the scissor arms have different lengths such that they position the roller device downwards away from the table top.
Further aspects of the present invention and further embodiments of the aspects described in the preceding paragraphs will become apparent from the following description, given by way of example and with reference to the accompanying drawings, in which:
At each end 14 of the table top 12 there is a downwardly depending leg 20. In the embodiment shown the legs 20 are rectangular panels having the same width between sides as the depth of the table top. The outer surfaces 22 of the legs 20 are generally planar. The thickness of the leg panels are also the same as the table top 12, such that a uniform, somewhat seamless appearance is provided by the table. Such a presentation means that table clothes are not required to cover the tables, as the tables are aesthetically pleasing. There is a recessed portion 24 on the inside of the legs 20 in order to reduce the weight of the legs and the overall assembly. Similarly, the underside of the table top has a recessed portion 26 to reduce weight (as shown in
It can be seen from
As can be seen best in
A single roller 34 is shown at each end of the table top, however it will be appreciated that more than one spaced apart roller may be used, although it is desirable that they share a common axle.
The legs 20 are connected to the table top 12 using standard mitre joint corner hinges 36. Two hinges 36 are provided, one towards each side 16 of the table top 12. A stabilising strut 38 is used in the centre at each end, with a first end 40 being pivotally connected to the leg 20 and a second end 42 being slidable connected to a rail 44 on the underside of the table top. As the leg 20 is folded, the second end 42 slides along the rail 44 towards the centre of the table top, as can be seen in
Referring to
Adjacent the ends of the hinge 36, at the end 14 of the table top and the upper end 30 of the leg, there are cut out portions 52, 54. The cut out portions 52, 54 together form a pocket 56 into which the roller 34 is partially or fully received when the leg is unfolded, as shown in
The roller 34 is connected at each end to a scissor link hinge 58. The scissor link hinge 58 is constructed from four arms, two shorter arms 60a, 60b and two longer arms 62a, 62b. The outer ends of the shorter arms 60, 60b pivotally join at roller axle 64. The shorter arms connect to the longer arms at pivot points 66a, 66b. The longer arms 62a, 62b cross over each other and are connected together at pivot point 68. The ends of the longer arms are then respectively joined to the first and second hinge brackets 46, 48 via pivot points 70a, 70b. These connections are such that, as the leg 20 is folded and the second bracket 48 is moved towards the first bracket 46, the end pivots 70a, 70b of the long arms 62a, 62b are moved together. This forces pivots 66a, 66b towards each other, lengthening the arms outwardly and extending the roller 34 outward from the pocket 56 between the end 14 of the table top and the end 30 of the leg, as shown in
The long arms 62a, 62b are of different lengths, with arm 62a being longer than arm 62b. The connecting pivot 68 is located half way along the length of the longer arm 62a. The pivot 68 placement on the shorter arm 62b is further towards the shorter arms. The result of this non symmetry is that as the scissor link hinge 58 extends outwardly from the pocket 56, the roller follows an arc and moved down so that it is closer to the edge 30 of the leg. When the folded table is tilted and rolled, because the roller is closer to the floor surface, the edges 14 and 30 are protected from damage and the table is not required to be lifted as high as if it extended evenly.
As the table is unfolded, the scissor link hinge 58 works in the reverse, with the first and second hinge brackets 46, 48 drawing apart. This moves the ends of the long arms 62a, 62b apart, which draws the roller inwards to sit within the pocket 56 as the corner closes.
