[0014] An object of the present invention is to provide an improved table transport device for transporting a plurality of tables.
[0015] This object is achieved by a device according to the independent claim.
[0016] Further training is specified in the dependent claims.
[0017] Embodiments of the present invention are based on the idea of creating a table transport device for the simultaneous transport of several tables or table tops, which, when unloaded, can be pushed together with several other identical table transport devices in a space-saving manner.
[0018] A table transport device for the simultaneous transport of several tables or table tops comprises several wheels on which the table transport device can be moved across a floor, a storage surface for supporting several table tops whose edges rest on the storage surface, and a leaning device for leaning a table top whose edge rests on the storage surface, wherein the table transport device is designed such that several unloaded, identically constructed and spatially identically oriented table transport devices can be arranged such that each table transport device rests on at least part of its wheels and is arranged at least partially in or under an adjacent table transport device, wherein the total length of the arrangement of two adjacent table transport devices is less than twice or one and a half times the length of a table transport device.
[0019] A table transport device for the simultaneous transport of several tables or table tops comprises several wheels on which the table transport device can be moved across a floor, a storage surface for supporting several table tops whose edges rest on the storage surface, a leaning device for leaning a table top whose edge rests on the storage surface, and a frame device on the underside of which the wheels and on the top of which the storage surface and the leaning device are arranged, wherein the table transport device is designed such that several unloaded, identically constructed and spatially oriented table transport devices can be arranged such that each table transport device rests at least on part of its wheels and is arranged at least partially in or under an adjacent table transport device,wherein the total length of the arrangement of two adjacent table transport devices is less than twice or one and a half times the length of one table transport device.
[0020] The table transport device is particularly designed and constructed for the simultaneous transport of several identical or similar tables or tabletops. The table transport device is particularly designed for the simultaneous transport of several tables with folding table legs, which are folded onto the tabletop during transport and arranged parallel to the tabletop. Such tables with folding table legs form flat and, in particular, essentially cuboid-shaped units in their transport configuration, which can be easily stacked vertically or placed upright on the table transport device with their edges resting on the storage surface, and can be arranged as a stack with a horizontal stacking direction.
[0021] The table transport device is intended and designed in particular for the simultaneous transport of several tables with rectangular table tops with widths in the range of 0.45 m or 0.6 m or 0.7 m to 1.0 m or 1.2 m and lengths in the range of 1.2 m or 1.5 m to 2.0 m or 2.5 m. In particular, the storage surface or surfaces are designed such that they can safely accommodate the short edge sections of table tops with the intended dimensions. For this purpose, the storage surface or surfaces have or have in particular an overall width that is at least 0.6 times or at least 0.8 times or at least 0.9 times the width of the table tops for which the table transport device is intended.
[0022] Alternatively or additionally, the table transport device can be designed for the simultaneous transport of several tables with circular, elliptical, oval, or other round tabletops with diameters or other dimensions in the range of 0.45 m, 0.6 m, 0.7 m, or 1.0 m, or 1.2 m, or 1.5 m. For this purpose, two storage surfaces have a maximum distance that is smaller or significantly smaller than the diameter or other dimension (not the thickness) of the tabletops for which the table transport device is intended. The storage surface or surfaces can be concave and / or inclined to avoid point loads on the edges of the tabletops.
[0023] Regardless of whether the table transport device is intended and designed for transporting rectangular and / or round table tops, the bearing surface or the bearing surfaces can be designed as surfaces of an elastic body which enables the bearing surface to be adapted to the shape of the edge of the transported table tops.
[0024] In particular, the reclining device is of such a height, or a reclining surface on the reclining device is of such a length, that the center of gravity of a table or tabletop with the intended maximum length is not located above, or not significantly above, the upper end of the reclining surface on the reclining device. In the intended use of the table transport device, a first tabletop rests directly against the reclining device, and additional tabletops can rest against the first tabletop in the form of a stack with a horizontal stacking direction.
[0025] The leaning device is particularly designed and configured such that, during the intended use of the table transport device, the table tops are not exactly vertical, but rather inclined toward the leaning device with a deviation from the vertical in the range of 5 degrees to 30 degrees or in the range of 10 degrees to 20 degrees. This inclination can prevent the table tops from tipping over even during acceleration or deceleration of the table transport device. Alternatively or additionally, the table transport device can be provided for securing the table tops using a tensioning belt or another securing device.
[0026] The wheels of the table transport device are arranged, in particular, at the corners of a triangle or a quadrilateral. The triangle or quadrilateral is, in particular, mirror-symmetrical to a plane that, during the intended use of the table transport device, is orthogonal to a floor on which the table transport device rests or rolls, and parallel to an intended main direction of movement of the table transport device.
[0027] During the intended use of the table transport device, the frame device is in particular parallel or substantially parallel to a floor on which the table transport device rests or rolls. The wheels are arranged in particular on the underside of the frame device facing the floor during the intended use of the table transport device. The storage surface and the leaning device are arranged in particular on or above the upper side of the storage surface facing away from the underside.
[0028] The table transport device is particularly designed such that several identically constructed and spatially oriented table transport devices, each resting on all of its wheels, can be arranged such that each table transport device is arranged at least partially within or beneath an adjacent table transport device. The table transport device, in particular, has a concave region whose shape allows it to accommodate at least part of an adjacent identically constructed and spatially oriented table transport device.
[0029] Several unloaded (or only partially loaded) table transport devices with the features and properties described here can be arranged in a space-saving manner, in particular at least partially nested. This can simplify the storage or keeping of unloaded (or only partially loaded) table transport devices and / or the simultaneous transport of several empty table transport devices.
[0030] In a table transport device as described here, the frame device has in particular a concave region, wherein the shape of the frame device is such that the frame device of the table transport device can be partially inserted into the concave region of the frame device of an identically constructed table transport device.
[0031] The frame device has, in particular, a concave region in plan view or in a section along a plane parallel to a floor on which the table transport device rests in the intended manner. The frame device and its concave region are, in particular, designed such that the frame device of a table transport device resting or rolling on a floor with all wheels in the intended manner can be arranged partially in the concave region of the frame device of an identically constructed table transport device, all of whose wheels rest on the same floor in the intended manner.
[0032] In a table transport device as described here, the concave region of the frame device is open in particular towards an end of the table transport device facing away from the leaning device.
[0033] If the leaning device is arranged at the rear end of the table transport device in the intended transport direction of the table transport device, the concave area is open in particular towards the front end of the table transport device.
[0034] In a table transport device as described here, the frame device has in particular a U-shaped or V-shaped configuration with two legs, wherein a wheel of the table transport device is arranged on each leg.
[0035] The two legs are, in particular, arranged substantially mirror-symmetrically to a plane which, during the intended use of the table transport device, is orthogonal to a floor on which the table transport device rests or rolls, and parallel to the intended main direction of movement of the table transport device. The two legs of the U-shaped or V-shaped frame device can enclose an angle in the range of 0 degrees to 30 degrees, in particular in the range of 5 degrees to 15 degrees or in the range of 10 degrees to 20 degrees. The frame device, in particular, has the shape of a letter U or V that is open towards the front or away from the backrest.
[0036] In a table transport device as described here, in particular the distance between two wheels near an end of the table transport device facing away from the leaning device is greater than the distance between two wheels near an end of the table transport device facing the leaning device.
[0037] In particular, in the intended main transport direction of the table transport device, the distance between two wheels at the front end of the table transport device is greater than the distance between two wheels at the rear end of the table transport device.
[0038] A table transport device as described here further comprises, in particular, at an end of the table transport device facing away from the leaning device, a niche for receiving a table leg of a table to be loaded onto the table transport device during the loading process or of a table to be unloaded from the table transport device during the unloading process.
[0039] The niche can simplify the loading and unloading of a table by temporarily partially accommodating a leg, allowing the table to be tilted to a position where an edge section of the tabletop already rests in its final position on the table transport device's support surface. This prevents a tabletop that is already resting upright or essentially upright on the table transport device's support surface from shifting relative to the table transport device. This can reduce both the time required and the effort required, and reduce the risk of damaging a tabletop.
[0040] In a table transport device as described here, the niche is in particular part of the concave area of the frame device, or the concave area of the frame device forms the niche.
[0041] In this case, the concave area of the frame assembly can serve a dual function. During storage of unloaded table transport devices, the concave area of one table transport device can accommodate part of another identical table transport device to reduce space requirements. During loading and unloading, the concave area can accommodate a table leg to simplify loading and unloading.
[0042] In a table transport device as described here, in particular the entire storage surface or a part of the storage surface is inclined.
[0043] The entire storage surface or one or more partial areas of the storage surface are inclined if they are not parallel to a floor on which the wheels of the table transport device rest as intended. The entire storage surface or one or more partial areas of the storage surface are inclined, particularly in the position intended for the transport of multiple tables and in the position present during the transport of multiple tables.
[0044] In a table transport device as described here, in particular a backrest of the backrest device is inclined and the storage surface or one or more partial areas of the storage surface are orthogonal or substantially orthogonal to the backrest.
[0045] The backrest is inclined if, during the intended use of the table transport device, it is not orthogonal to a floor on which the wheels of the table transport device rest in the intended manner. The backrest forms an angle with a vertical line to the floor in particular in the range of 5 degrees to 30 degrees or in the range of 10 degrees to 20 degrees. The deviation of the angle between the backrest of the backrest and the storage surface or a sub-area of the storage surface from a right angle is in particular smaller or much smaller (i.e. at most one fifth or at most one tenth) than the angle of inclination of the backrest and than the angle of inclination of the storage surface or of the sub-area(s) of the storage surface. The angle of inclination of the backrest is the angle between the backrest and the vertical line to the floor.The angle of inclination of the storage area or part(s) of the storage area is the angle between the storage area or part(s) of the storage area and the floor.
[0046] The inclination of the backrest and the storage area or parts of the storage area can enable particularly safe storage of one or more table tops on the table transport device.
[0047] In a table transport device as described here, in particular the frame device is inclined and the storage surface is parallel to the frame device.
[0048] The frame assembly is tilted if, during the intended use of the table transport device, it is not parallel to a floor on which the table transport device rests or rolls.
[0049] In a table transport device as described here, the frame device comprises in particular two or more longitudinal beams, on each of which at least one bearing surface is provided, wherein the longitudinal beams are inclined in the longitudinal direction and the bearing surfaces are parallel to the longitudinal beams.
[0050] The longitudinal beams are inclined longitudinally if, during the intended use of the table transport device, they are not parallel to a floor on which the table transport device rests or rolls. The angles between the longitudinal beams and the floor are, in particular, in the range of 5 degrees to 30 degrees or in the range of 10 degrees to 20 degrees.
[0051] In a table transport device as described here, in particular a wheel near an end of the table transport device facing away from the leaning device has a larger diameter than a wheel near an end of the table transport device facing the leaning device.
[0052] Different wheel diameters can allow for tilting the frame. Especially at the front end of the table transport device, a larger wheel diameter can significantly improve rolling characteristics—for example, when crossing thresholds or other small obstacles.
[0053] In a table transport device as described here, the bearing surface has, in particular, a sawtooth-shaped profile in its longitudinal section.
[0054] The dimensions of the sawtooth-shaped profile of the support surface are adapted in particular to the inclination of the backrest and to the thickness of a table top for which the table transport device is intended, so that each table top rests on its own flat or substantially flat section of the support surface.
[0055] A table transport device as described here further comprises, in particular, a support device, the upper side of which forms the storage surface, wherein the support device is formed from an elastic foam, a rubber, an elastomer or another elastic material.
[0056] A support system made of an elastic material can significantly reduce the risk of damage to the edge of a transported tabletop. The elastic material can also provide high static friction, thus reducing the risk of tabletops slipping during transport.
[0057] A table transport device as described here further comprises, in particular, a support device, the upper side of which forms the storage surface, wherein the frame device has a longitudinal beam with an upwardly open cross-section, and wherein the support device is arranged in the longitudinal beam and protrudes from the longitudinal beam with the storage surface.
[0058] The longitudinal beam of the frame device forms, in particular, one leg of a U- or V-shaped frame device. A wheel of the table transport device is arranged, in particular, on the underside of the longitudinal beam. The cross-section of the longitudinal beam has, in particular, a U-shaped cross-section with three straight sections towards the top (i.e., towards a side facing away from a floor on which the table transport device rests or rolls in the intended manner). The support device can be formed by a wooden component, for example a wooden beam, filling the cross-section of the longitudinal beam and protruding upward from the longitudinal beam.
[0059] The support device can be provided with a sawtooth-shaped surface protruding from the longitudinal beam, wherein the sawtooth-shaped surface can be adapted to the inclination of the support device and to the thicknesses of the table tops to be transported.
[0060] A table transport device as described here further comprises, in particular, a support device, the upper side of which forms the storage surface, wherein the support device is connected in an articulated manner to the frame device.
[0061] The support device is pivotable relative to the frame device, in particular, about a transverse axis or about an axis transverse to the intended main transport direction of the table transport device. The support device can be plate-shaped, on the one hand, to enable the transport of smaller objects using the table transport device, and on the other hand, its pivotability allows for partial nesting of several table transport devices, thus enabling a space-saving arrangement of empty table transport devices.
[0062] In a table transport device as described here, the support device is pivotable in particular relative to the frame device about a pivot axis near the end of the table transport device facing the leaning device.
[0063] The following examples are explained in more detail using the attached figures. They show: Fig. 1 a schematic axonometric representation of a table transport device; Fig. 2 a schematic representation of the table transport device from Fig. 1; Fig. 3 a further schematic representation of the table transport device from the Fig. 1 and Fig. 2; Fig. 4 a schematic enlarged view of a part of a variant of the table transport device from the Fig. 1 to 3; Fig. 5 a schematic enlarged view of a part of another variant of the table transport device from the Fig. 1 to 3; Fig. 6 a schematic representation of another table transport device; Fig. 7 a schematic representation of another table transport device; Fig. 8 a schematic representation of another table transport device; Fig. 9 a schematic representation of another table transport device; Fig. 10 is a schematic representation of another table transport device; Fig. 11 a schematic representation of another table transport device; Fig. 12 a schematic representation of a support device of the table transport device from Fig. 11.
[0064] Fig. Figure 1 shows a schematic axonometric view of a table transport device 20 for the simultaneous transport of several tables or table tops. The outlines of a table top 14 are shown in Fig. 1 by a dashed line. The table transport device 20 comprises a frame device 40 and a leaning device 60.
[0065] The frame assembly 40 comprises two longitudinal beams 44 and a transverse beam 45 connecting two ends of the longitudinal beams 44. The longitudinal beams 44 and the transverse beam 45 of the frame assembly 40 together have the shape of a square letter U.
[0066] At the presentation in Fig. 1 Wheels 31, 32 are arranged on the underside of the frame device 40, facing away from the viewer. The wheels 31, 32 are designed and constructed to rest or roll on a floor. When all wheels 31, 32 rest or roll on a floor simultaneously, the longitudinal beams 44 and the transverse beam 45 of the frame device 40 are parallel or substantially parallel to the floor.
[0067] A wheel 31 is provided near the end of each longitudinal beam 44 spaced apart from the cross beam 45 of the frame device 40. In the example shown, a further wheel 32 is provided in the middle of the cross beam 45 of the frame device 40. Deviating from the illustration in Fig. 1, four (or more) wheels 31, 32 can be provided, in particular two wheels 32 on the cross member 45 or on the ends of the longitudinal members 44 facing the cross member 45.
[0068] All wheels 31, 32 are swivel casters whose horizontal rolling axes can also pivot about a vertical axis, so that the table transport device 20 can be moved in all directions at any time. Alternatively, at least some of the wheels 31, 31 can be designed as fixed casters, each of which can only roll in one direction.
[0069] The leaning device 60 of the table transport device 20 is on the side facing away from the floor and in the illustration in Fig. 1 arranged on the top side of the frame device 40 facing the viewer. The leaning device 60 comprises two inclined beams 61, two support beams 62, and a cross beam 65. One end of each inclined beam 61 of the leaning device 60 is connected to the frame device 40, in the example shown to one of the two longitudinal beams 44 of the frame device 40. One end of each support beam 62 is connected to the frame device 40, in the example shown to a corner area between a longitudinal beam 44 and the cross beam 45 of the frame device 40. Another, upper end of each support beam 62 is connected to an inclined beam 61. In the example shown, the upper ends of an inclined beam 61 and a support beam 62 of the leaning device are connected. The cross beam 65 connects the two inclined beams 61 and / or the two support beams 62.In the example shown, the cross member 65 connects the ends of the inclined members 61 and the support members 62 facing away from the frame device 40.
[0070] When the table transport device 20 rests or rolls in the intended manner with all wheels 31, 32 on a horizontal floor, in particular the support beams 62 are vertical or substantially vertical and the cross beam 65 is horizontal, and the inclined beams 61 enclose an angle with the vertical in the range of 5 degrees to 30 degrees, in particular an angle in the range of 10 degrees to 20 degrees.
[0071] Handles 70 are provided on the backrest 60, by means of which the table transport device 20 can be moved manually. In the example shown, the handles 70 are formed by the ends of a horizontal tube projecting beyond the backrest. Deviating from the illustration in Fig. 1, the tube, the ends of which form the handles 70, and the cross member 65 of the leaning device 60 can be identical.
[0072] On the sides facing away from the floor and in the representation in Fig. 1 On the upper sides of the longitudinal beams 44 facing the viewer, storage surfaces 54 are provided on which table tops 14 can be stored. During the intended use of the table transport device 20, one or more table tops 14 are placed upright on the storage surfaces 54 and leaned against backrests 64 on the inclined beams 61 of the leaning device 60.
[0073] The table transport device 20 is particularly provided and designed for rectangular table tops 14 with dimensions within a predetermined range. The table transport device 20 is particularly designed for rectangular table tops 14 with a width in the range of 0.6 m or 0.7 m to 0.9 m or 1.0 m and a length in the range of 1.2 m or 1.5 m to 2.0 m or 2.5 m. The maximum distance between the longitudinal beams 44 is smaller than the minimum width of table tops 14 for the transport of which the table transport device 20 is provided. The length of the backrests 64 on the inclined beams 61 of the backrest 60 is particularly at least half the maximum length of a table top 14 for the transport of which the table transport device 20 is provided. The center of gravity of a table top 14 in the provided and in Fig. 1 indicated position on the table transport device 20 is therefore not located above the upper end of the leaning device 60.
[0074] The table transport device 20 is particularly provided and designed to be pushed by a person who grasps one of the two handles 70 of the table transport device 20 with each hand. With respect to this preferred direction of movement of the table transport device 20 (in the illustration in Fig. 1: bottom left), the ends of the longitudinal beams 44 of the frame device 40 facing away from the leaning device 60 and the cross beam 45 form a front end 21 and the cross beam 45 of the frame device 40 with the ends of the longitudinal beams 44 arranged thereon and the leaning device 60 form a rear end 22 of the table transport device 20.
[0075] The table transport device 20 has a niche 24 at its front end 21 between the longitudinal beams 44 of the frame device 40. During loading and unloading, table legs of tables that are to be loaded onto the table transport device 20 or of tables that are to be unloaded from the table transport device 20 can be arranged in the niche 24. This is with reference to Fig. 9 described in more detail.
[0076] The frame device 40 comprises a concave region 41 formed by the mutually facing inner sides of the longitudinal beams 44 and the side of the transverse beam 45 facing the front end 21. In the example shown, the concave region 41 of the frame device 40 encloses the niche 24. The shape of the concave region 41 is selected such that another, identically constructed table transport device can be partially accommodated in the space enclosed by the concave region 41 of the frame device 40.
[0077] Fig. 2 shows a further schematic representation of the table transport device 20 from Fig. 1 together with two other table transport devices, indicated by dashed lines, of the same construction and oriented in the same space. The drawing plane of the Fig. 2 is parallel to a floor on which the table transport devices 20 each rest or roll with all their wheels.
[0078] In Fig. 2 that the longitudinal beams 44 of the frame device 40 are not parallel to one another, but enclose an angle, so that the distance between the longitudinal beams 44 is greater at the front end 21 than at the rear end 22 of each table transport device 20. The niche 24 of each table transport device 20 enclosed by the concave region 41 of the frame device 40 therefore has a substantially trapezoidal plan.
[0079] The trapezoidal outline of the niche 24 enclosed by the concave area 41 essentially corresponds to the trapezoidal outer contour of the frame device 40 of the table transport device 20 at its rear end 22. Therefore, the rear end of an identically constructed table transport device can be inserted into the concave area 41 of the table transport device 20, which is open towards the front end 21 of the table transport device 20. In this way, any number of table transport devices 20, which rest or roll with all their wheels 31, 32 in the intended manner on a flat floor and are oriented the same way in space, can be pushed into one another. This is Fig. 2. The space requirement of this arrangement of several table transport devices 20 is significantly smaller than the sum of the space requirements of each individual table transport device 20. In addition, in the Fig. 2, several empty table transport devices 20 can be easily moved simultaneously, in particular pushed from an event room into a storage room or vice versa.
[0080] Fig. 3 shows a further schematic representation of the table transport device 20 from the Fig. 1 and Fig. 2. The drawing level of the Fig. 3 is orthogonal to the plane of the Fig. 2 and orthogonal to a floor 19 on which the table transport device 20 rests or rolls with all its wheels 31, 32 in the intended manner. In addition to the table transport device 20, Fig. 3, several table tops 14 are indicated by dashed lines, which are mounted on the table transport device 20 in the intended manner.
[0081] In Fig. 3 it can be seen that in the example shown the longitudinal beams 44 of the frame device 40 of the table transport device 20 are arranged parallel to the floor 19 and the support beams 62 of the leaning device 60 are arranged orthogonally to the floor 19.
[0082] Each table top 14 rests with a straight section of its edge 15 on bearing surfaces 54 on the upper sides of the longitudinal beams 44 facing away from the floor 19. The upper side 17 of a table top 14 leans against the leaning surfaces 64 on the inclined beams 61 of the leaning device 60. Further table tops 14 form a stack with a horizontal stacking direction, wherein in particular the upper side 17 of each table top 14 leans against the underside 16 of an adjacent table top 14. The bearing surfaces 54 on the upper sides of the longitudinal beams 44 of the frame device 40 are designed to be non-slip, for example with a rubber layer or in some other way, in order to ensure a high level of static friction between the edges 15 of the table tops 14 and the bearing surface 54.
[0083] Fig. 4 shows a schematic enlarged view of a part of a variant of the Fig. 1 to 3 shown table transport device 20. The type of representation in Fig. 4 corresponds largely to that of the Fig. 3. In particular, the drawing level of the Fig. 4 orthogonal to a floor on which the table transport device 20 rests.
[0084] The Fig. 4 is similar in some features, properties and functions to the table transport device 20 shown in the Fig. 1 to 3. The following are the features, characteristics and functions of the table transport device shown in Fig. 4, in which they differ from the one shown in the Fig. 1 to 3 shown table transport device.
[0085] The Fig. The table transport device 20 shown in Figure 4 differs from the one shown in Figure 4. Fig. 1 to 3, in particular in that the bearing surface 54 on each longitudinal beam 44 is formed by a thick and elastic support device 50. The elasticity of the support device 50 is selected such that a table top 14 with a predetermined mass and a predetermined width of the edge 15, for which the table transport device 20 is provided, significantly deforms the support device 50. In Fig. 4 it is indicated that the table top 14 supports the support device 50 starting from its Fig. 4 is compressed to such an extent that the edge 15 of the table top 14 rests against the bearing surface 54 over its entire width. The elastic deformation, namely compression of the support device 50, is indicated by dashed lines, which have uniform spacing in the undeformed area of the support device 50 and reduced spacing in the compressed area of the support device 50.
[0086] The support device 50 can be formed from rubber, an elastomer, or another elastic material. The support device 50 can have regularly arranged or irregularly arranged cavities (for example, as an elastic rigid foam). The bearing surface 54 on the upper side of the support device 50 can be structured or profiled and / or have a coating. The support device 50 can be glued to the longitudinal beam 44 or attached to it in some other way and / or can be arranged partially within an upwardly open cross-section of the longitudinal beam 44, such that the bearing surface 54 protrudes upward from the cross-section of the longitudinal beam 44.
[0087] Fig. 5 shows a schematic enlarged view of a part of another variant of the Fig. 1 to 3 shown table transport device 20. The type of representation in Fig. 5 corresponds largely to that of the Fig. 3 and Fig. 4. In particular, the drawing level of the Fig. 5 orthogonal to a floor on which the table transport device 20 rests.
[0088] The Fig. The table transport device 20 shown in Figure 5 is similar in some features, properties and functions to the Fig. 1 to 4. The following are the features, characteristics and functions of the table transport devices shown in Fig. 5 shown table transport device 20, in which these differ from the ones shown in Fig. 1 to 4 shown table transport device.
[0089] The Fig. The table transport device 20 shown in Figure 5 differs from the Fig. 1 to 4, in particular in that the contour of the support device 50 and the bearing surface 54 on the support device 50 are sawtooth-shaped in the longitudinal direction. The bearing surface 54 thus has a plurality of parallel and flat sub-regions, each of which is orthogonal to the backrest surface 64. The lengths of the flat sub-regions of the bearing surface 54 are adapted to the thicknesses of the tabletops 14, i.e., to the widths of the edges 15 of the tabletops 14 for which the table transport device 20 is intended.
[0090] The support device 50 is formed in particular from a wooden beam which is partially arranged within an upwardly open cross-section of the longitudinal beam 44 and protrudes so far from the cross-section of the longitudinal beam 44 that the flat partial regions of the bearing surface 54 are arranged completely outside the cross-section of the longitudinal beam 44.
[0091] In order to adapt the table transport device 20 to tables or table tops with different dimensions, in particular different thickness of the table top, the support device 50 can be removed from the longitudinal beam 44 and replaced by another support device with different dimensions of the flat partial areas of the storage surface 54.
[0092] Fig. 6 shows a schematic representation of another table transport device 20, which in some features, properties and functions corresponds to the one shown in the Fig. 1 to 5. The type of representation corresponds to that of the Fig. 3 to 5, in particular the drawing level of the Fig. 6 orthogonal to a floor 19 on which the table transport device 20 rests. In particular, features, properties and functions of the Fig. 6, in which they differ from those shown in the Fig. 1 to 5 shown table transport devices.
[0093] The Fig. The table transport device shown in Figure 6 differs from the ones shown in Figure 6. Fig. 1 to 5, in particular in that the bearing surfaces 54, although continuously flat, are not parallel to the floor 19 on which the wheels 31, 32 of the table transport device 20 rest or roll in the intended manner. The bearing surfaces 54 are orthogonal to backrest surfaces 64 on inclined beams 61 of the backrest device 60. The angle between the bearing surfaces 54 and the floor 19 corresponds to the angle between the backrest surfaces 64 on the inclined beams 61 and the vertical on the floor 19.
[0094] In the example shown, the longitudinal beams 44 of the frame device 40 of the table transport device 20 are parallel to the floor 19. The distance between the bearing surfaces 54 and the longitudinal beams 44, which increases towards the front end 21 of the table transport device 20, is generated, for example, by wedge-shaped support devices 50.
[0095] In the Fig. In the example shown in Figure 6, one of the tables is shown with table legs 12 that are spread apart from its table top 14. The table legs 12 assume the positions relative to the table top 14 that are intended for the use of the table 10. For transport and storage of the table 10, the table legs 12 can be folded against the table top 14, pivoting about axes orthogonal to the plane of the drawing of the Fig. 6 can be pivoted and sunk into a shallow cavity on the underside 16 of the table top 14.
[0096] In Fig. 6 further shows a tensioning belt 90, by means of which the entire stack of tables or table tops can be fastened to the leaning device 60.
[0097] Fig. 7 shows a schematic representation of another table transport device 20, which in some features, properties and functions corresponds to the one shown in the Fig. 1 to 6. The type of representation, in particular the drawing plane of the Fig. 7 corresponds to that of the Fig. 3 to 6. The following are in particular the features, characteristics and functions of the Fig. 7, in which they differ from those shown in the Fig. 1 to 6 shown table transport devices.
[0098] The Fig. The table transport device shown in Figure 7 differs from the ones shown in Figure Fig. 1 to 6, in particular in that the wheels 31 at the front end 21 of the table transport device have a larger diameter than the wheel(s) 32 at the rear end 22 of the table transport device. Therefore, the longitudinal beams 44 of the frame device 40 of the table transport device 20 are not parallel to a floor 19 on which the wheels 31, 32 of the table transport device rest in the intended manner, but are inclined. The inclined beam 61 of the leaning device 60 is orthogonal to the longitudinal beams 44 of the frame device 40. In the example shown, no support beam is provided.
[0099] Fig. Figure 8 shows a schematic representation of another table transport device 20, which in some features, properties and functions corresponds to the one shown in the Fig. 1 to 7, in particular the table transport devices shown in the Fig. 7. The type of representation in Fig. 8, in particular the orientation of the drawing plane corresponds to that of the Fig. 3 to 7.
[0100] Similar to the Fig. The table transport device shown in Figure 7 also has the Fig. 8, the table transport device 20 has inclined longitudinal beams 44. Unlike the one shown in the Fig. However, in the table transport device shown in Figure 7, this is not due to the different size wheels 31, 32. The wheels 31, 32 of the table transport device shown in Fig. 8 are of equal size. The inclination of the longitudinal beams 44 is a result of a different mechanical connection of the wheels 31 at the front end 21 and the wheels 32 at the rear end 22 of the table transport device.
[0101] In the Fig. In the example shown in Fig. 8, the wheels 32 are arranged at the rear end 22 of the table transport device 20 such that the rear ends of the longitudinal beams 44 are at a smaller distance from the floor 19 than the uppermost points of the rear wheels 32. For this purpose, the wheels 32 are not attached directly to the longitudinal beams 44, but rather to the leaning device 60.
[0102] Furthermore, the Fig. In the example shown in Figure 8, the wheels 31 at the front end 21 of the table transport device 20 are not attached directly to the longitudinal beams 44, but rather spaced apart from them, so that the front ends of the longitudinal beams 44 lie significantly above the uppermost points of the wheels 31. In particular, the wheels 31 at the front end 21 are connected to the longitudinal beams 44 via pedestals or columns.
[0103] Similar to the one based on the Fig. The example shown in Figure 7 is also the case in Fig. In the example shown in Figure 8, the inclined beam 61 of the leaning device 60 is orthogonal to the longitudinal beams 44 of the frame device 40, and no support beam is provided.
[0104] Fig. 9 shows a schematic representation of another table transport device 20, which in some features, properties and functions corresponds to the one shown in the Fig. 1 to 8, in particular the table transport devices shown in the Fig. 6. The type of representation in Fig. 9, in particular the orientation of the drawing plane corresponds to that of the Fig. 3 to 8.
[0105] In Fig. 9 is the effect of a niche 24, as shown by the Fig. 1 and Fig. 2, can be seen at the front end 21 of the table transport device 20. A table 10 comprises a table top 14 with a bottom 16 and a top 17 and two table legs 12, of which Fig. 9 only one is visible. Each table leg 12 has essentially the shape of an inverted letter T with a vertical and a horizontal bar. The upper end of the vertical bar is hinged to the table top 14 and can be Fig. 9 shown position orthogonal to the table top 14. The lower end of the vertical bar is connected to the horizontal bar, which is orthogonal to the plane of the drawing of the Fig. 9 and extends parallel to the floor 19.
[0106] Based on the Fig. 1 and Fig. 2 shown niche 24 at the front end 21 of the table transport device 20, the table transport device 20 can be moved up to the Fig. 9 shown position to the table. In the position shown in Fig. In the position of the table transport device 20 shown in Figure 9, the vertical bar of the table leg 12 is arranged in the niche 24.
[0107] Based on the Fig. 9 in solid lines, the table 10 can be adjusted to the configuration shown in Fig. 9 by dashed contours, in which the edge 15 of the table top 14 rests close to the leaning device 60 on the support surface 54. During the tilting of the table 10 from the position shown in Fig. 9 in solid lines to the position shown in Fig. 9 dashed lines, the table leg 12 is moved into the position shown in the Fig. 1 and Fig. 2 shown niche 24. Since the edge 15 of the table top 14 of the table 10 to be loaded onto the table transport device 20 is pivoted inwards due to the Fig. 1 and Fig. 2 can directly contact the support surface 54 at the backrest 64, the table top 14 then only needs to be tilted further until the upper side 17 of the table top 14 rests against the backrest 64. Therefore, it is not necessary to move the table top 14 on the support surface 54.
[0108] Fig. 10 shows a schematic representation of another table transport device 20, which in some features, properties and functions corresponds to the one shown in the Fig. 1 to 9 shown table transport devices.
[0109] The type of representation, especially the orientation of the drawing plane, corresponds to that of the Fig. 2, the drawing level of the Fig. 10 is thus parallel to a floor on which the table transport device 20 rests or rolls in the intended manner. The following are particularly the features, properties and functions of the Fig. 10 shown table transport device 20, in which these differ from the ones based on the Fig. 1 to 9 shown table transport devices.
[0110] The Fig. 10 shown table transport device 20 differs from the ones shown in the Fig. 1 to 9, in particular in that the longitudinal beams 44 of the frame device 40 have a smaller distance at the front end 21 of the table transport device 20 than at its rear end 22. In addition, no cross beam 45 (cf. Fig. 1) at least no transverse beam is provided at the level of the longitudinal beams 44. The frame device 40 thus has a concave region 41 open toward the rear end 22 of the table transport device 20, into which the front end 21 of an identically constructed table transport device 20 can be inserted.
[0111] The longitudinal beams 44 of the frame device 40 are connected near the front end 21 of the table transport device 20 by a substantially U-shaped or Ω-shaped (omega-shaped) component 46. The U-shaped or Ω-shaped component 46 encloses a niche 24 open towards the front end 21 of the table transport device 20 with the Fig. 9 shown function.
[0112] Deviating from the representation in Fig. 10, instead of the U-shaped or Ω-shaped (omega-shaped) component 46, for example, a straight cross member can be provided at the rear end of the niche 24 (facing away from the front end 21 of the table transport device 20), which cross member connects the longitudinal members 44 to one another.
[0113] Fig. 11 shows a schematic representation of another table transport device, which in some features, properties and functions corresponds to the one shown in the Fig. 1 to 10 and in particular the table transport devices shown in the Fig. 10. The type of representation, in particular the orientation of the drawing plane of the Fig. 11 corresponds to that of the Fig. 3 to 9. The following are in particular the features, characteristics and functions of the Fig. 11 shown table transport device 20, in which these differ from the one based on the Fig. 10 shown table transport device.
[0114] The Fig. The table transport device shown in Figure 11 differs from the one shown in Figure Fig. 10, in particular in that a plate-shaped support device 50 is provided which is pivotable relative to the frame device 40. The support device 50 has, near the rear end 22 of the table transport device 20, a shaft 51 which is pivotally mounted in one or more bearings on the frame device 40 or on the leaning device 60 and has a pivot axis 58 orthogonal to the plane of the drawing of the Fig. 11. In the Fig. In the example shown in Figure 11, the edge of the support device 50 is beveled near the front end 21 of the table transport device 20. When pushing together several identical table transport devices 20, in each of which the front end 21 of a table transport device 20 is inserted into the concave region 41 of the frame device 40, which is open towards the rear end 22 of the table transport device 20 (see Figure 11). Fig. 10), the support devices 50 of the table transport devices are pivoted upwards by a few degrees about their pivot axes 58. This is indicated by an inclined contour and a circular arc along which the front end of the support device 50 is then moved.
[0115] The flat carrying device 50 can enable the transport of objects that are significantly smaller than table tops.
[0116] Fig. 12 shows a schematic representation of the support device 50 of the Fig. 11 shown table transport device 20. The drawing plane of the Fig. 12 is orthogonal to the plane of the Fig. 11 and parallel to a floor on which the wheels 31, 32 rest or roll in the intended manner.
[0117] The ends of the shaft 51 project laterally relative to the remaining support device 50 in order to be inserted into bearing shells on the frame device 40 or on the leaning device 60 of the table transport device 20 (cf. Fig. 11). The width of the support device 50 increases towards the front end 21 of the table transport device 20 (cf. Fig. 11). Furthermore, the support device 50 has a niche 24 open towards the front end, which corresponds to the niche enclosed by the U-shaped or Ω-shaped component 46 in the frame device 40 (cf. Fig. 10). Bearing surfaces 54 are formed on the upper side of the support device 50, for example, from rubber or another elastic and / or high-friction material.
