Description




The invention relates to a table with a table top and a table frame, wherein the table top is hinged on the table frame so as to be pivotable about a horizontal pivot axis. The table frame has a horizontal beam, at least one support part for supporting the table top and one or more table legs coupled to the support part. The support part is movable transversely with respect to the pivot axis between a working position and a stacking position or is coupled to the beam so as to be pivotable about a vertical axis.




Such tables are known for example as conference room tables. A different number of tables must be set tip depending upon the occupancy of a conference room. The tables which are not required are stacked to save space.




A table according to the preamble to Claim is known from EP-A-0 572 770. This table has two table legs which are constructed as vertical supporting struts and in the base region bear crossbars which are supported on the floor by way of feet. The crossbars of the table legs are parallel to one another in the working position of the table top and extend in the direction of the depth of the table. In order to bring this table from the working position into the stacking position, first of all both supporting struts must be folded inwards so that the table top can then be folded downwards. Two people are usually required for this operation.




The object of the invention, therefore, is to improve the table according to the preamble to claim


1


in such a way that it is also easily possible for one person to bring the table from the working position into the stacking position and vice versa.




This object is achieved by the features of claim


1


.




Further embodiments of the invention are the subject matter of the subordinate claims.




According to the invention the table has a table top and a table frame, wherein the table frame has a horizontal beam, at least one support part for supporting the table top and one or more table legs coupled to the support part. The table top is hinged on the beam so as to be pivotable about a horizontal pivot axis, and the support part is movable transversely with respect to the pivot axis between a working position and a stacking position or is coupled to the beam so as to be pivotable about a vertical axis. Furthermore, between the table top and the support part coupling means are provided which effect common pivoting or turning of the table top and of the table leg coupled to the support part.




As a result, the table can be brought from the working position into the stacking position by simply folding down the table top, optionally after unlocking. In this case the table legs are automatically pivoted or turned with it. Conversely, by raising the table top the table can likewise be brought into the working position in a simple manner by one person.




In a special embodiment of the invention the table legs are constructed as vertical supporting struts which in the base region bear horizontal crossbars which are supported on the floor by way of feet or castors. In this case the crossbars are disposed outside the pivoting range of the table top and in the working position of the table top they are parallel to one another and extend in the direction of the depth of the table, whilst in the stacking position they are disposed at an angle following the movement of the support parts relative to one another.




The angular position of the crossbars in the stacking position ensures that in this position also the table can stand up by itself with the table top folded down. If the crossbars are provided with castors, the table can also be moved in a simple manner in the stacking position. Furthermore, the angular position of the crossbars also ensures that in the stacking position a plurality of tables can be pushed into one another or placed one behind the other, resulting in a very space-saving arrangement of the tables in the stacking position.

A first embodiment is shown in

FIGS. 1

to


5


. The table essentially consists of a table top


10


and a table frame, the table top being hinged on the table frame so as to be pivotable about a horizontal pivot axis


11


.


1


. The table frame has a horizontal beam


12


, at least one support part


14


for supporting the table top


10


and one or more table legs non-rotatably coupled to the support part. The support part


14


is coupled to the beam


12


so as to be movable transversely with respect to the pivot axis


11


.


1


or pivotable about a vertical axis


14


.


4


between a working position (

FIGS. 2

,


3


) and a stacking position (

FIGS. 4

,


5


). The table top


10


is pivotably hinged on the beam


12


by way of hinges


11


.




The table also has a transverse support


21


which is disposed transversely with respect to the beam


12


and has a groove


21


.


2


in a central portion


21


.


1


which is curved in an approximately arcuate shape.




The support part


14


is constructed in the manner of an outrigger and is held with its end


14


.


5


articulated on the beam


12


, whilst the other end


14


.


6


is guided in the groove


21


.


2


in the transverse support


21


. In this case the end


14


.


6


is for example constricted as a guide lug of a guide roller. At least in the working position of the table a suitable locking means should be provided in order to fix the end


14


.


6


of the support element


14


releasably at one end of the groove


21


.


2


. This can be effected for example by a corresponding shaping of the groove or other means.




In the working position of the table the support part


14


is oriented at an angle of for example 45° to the extension of the beam


12


.




The table leg


18


is provided in its lower region with a crossbar


16


which in turn has feet or castors


17


. In the working position of the table the crossbar is oriented substantially perpendicular to the beam


12


(see FIG.


3


). Since the table leg


18


is rigidly connected to the support element


14


, the crossbar


16


is correspondingly moved during a pivoting movement of the support part


14


. In the stacking position the two opposing crossbars are oriented in a V shape relative to one another (see FIG.


5


). In this position a plurality of tables can be stacked in one another to save space. Such stacking is particularly simple when the crossbars are provided with castors


17


, so that the folded tables can be moved without effort.




In

FIGS. 6

to


10


a second embodiment is shown in which coupling means which effect a common pivoting or turning of the table top and table leg are again provided between the table top and the support part.




For corresponding parts the same reference numerals as in

FIG. 1

are used.




Here too the table top


10


is pivotably mounted on the beam


12


by way of hinges


11


. The support part


14


is again articulated by its end


14


.


5


on the beam


12


. The table leg


18


is also fixed on this end


14


.


5


.




The coupling means for common pivoting of the table top and support part are formed in the illustrated embodiment by toothed wheels, particularly by two mitre wheels


22


.


1


,


22


.


2


. One mitre wheel


22


.


1


is fixed to the support element


14


in the region of its end


14


.


5


, whilst the other mitre wheel


22


.


2


, which engages with the other mitre wheel


22


.


2


, is fixed on the transverse support


21


or on the table top


10


.




Since the forces acting on the table top


10


cannot be absorbed solely by the mitre wheels, the support part


14


is constructed as a outrigger on which the table top can be supported (see FIG.


8


). In this case the outrigger should be releasably locked in a suitable manner in the working position of the table.




In the working position the support element


14


is oriented at an angle to the beam


12


. However, if the table top


10


is pivoted into the stacking position (

FIG. 10

) the support element


14


and the beam


12


are parallel to one another. Due to the pivoting of the support element


14


the table leg is also turned, so that the crossbar


16


in turn assumes an angle of approximately 45° relative to the table top


10


and thus requires less stacking space.




A third, preferred embodiment is described below with reference to

FIGS. 11

to


18


. Here too the same reference numerals are used for the same parts.




The table consists essentially of a table top


10


and a table frame which has a horizontal beam


12


, at least one support part


14


for supporting the table top and one or more table legs


18


coupled to the support part. The table top


10


is hinged on the beam


12


by way of hinges


11


so as to be pivotable about a horizontal pivot axis. The support part


14


is coupled to the beam


12


so as to be movable transversely with respect to the pivot axis or pivotable about a vertical axis


14


.


4


between a working position (

FIG. 11

) and a stacking position (FIG.


13


).




Between the table top


10


and the support part


14


coupling means are also provided which effect a common pivoting or turning of the table top


10


and of the table leg


18


coupled to the support pale


14


. In this embodiment these coupling means are constructed in such a way that the support part


14


articulated by one end


14


.


5


on the beam


12


is guided with its other end


14


.


6


in a guide profile


23


fixed on the table top


10


. The guide profile is constructed as a frame and has a guide groove


23


.


2


in which the end


14


.


6


of the support part


14


is guided by means of a suitable bearing


24


.




As can be seen in particular from

FIG. 12

, a first support part


14


is articulated on each end of the beam


12


, each first support part being connected to a table leg


18


. In addition to the first support part


14


a second support part


15


is also provided which is likewise pivotable about the vertical axis


14


.


4


, but independently of the first Support part


14


. This second support part


15


is likewise in contact with the guide profile


23


by its end


15


.


1


which is opposite the vertical axis


14


.


4


. The end


15


.


1


of the second support part


15


is provided on its upper face facing the table top


10


with a suitable bearing


15


.


2


which co-operates with a corresponding guide track


23


.


2


on the guide profile


23


. The bearing


15


.


2


can be formed for example by a roller bearing which can roll on the guide track


23


.


2


.




As can be seen in particular from

FIG. 12

, the first support part


14


and the second support part


15


are disposed approximately in the shape of a V relative to one another in the working position of the table. In addition to supporting the table top


10


, the first support part


14


also serves as a connecting member between the table top


10


and the table legs


18


in order to effect the synchronized turning of the legs when the table top is being folded down. The second support part


15


serves essentially for the additional support of the table top and in this embodiment also has the function of locking the table top in the working position.




The second support part


15


is also biased by a spring element, which is not shown in further detail, in such a way that it moves automatically from the stacking position into the working position as soon as the table top is oriented horizontally. At the end of its movement the end


15


.


1


of the second support part


15


comes into locking contact with a locking mechanism


25


which is merely indicated schematically.




Thus the first support part


14


moves during the entire process of pivoting the table top from the stacking position to the locking position of the support element. On the other hand, the second support element


15


is only pivoted out automatically due to the spring element when the table top has been brought into the horizontal working position. For unlocking of the locked second support element


15


an unlocking mechanism


26


is provided which is indicated schematically in

FIG. 12

,


13


and


14


and is in operative connection with the locking mechanism


25


.




The unlocking mechanism


26


has for example on its one end


26


.


1


a suitably constructed handle with the aid of which the unlocking mechanism can be moved in the direction of the arrow


27


(FIG.


12


). During the movement in the direction of the arrow


27


an entrainment lug


26


.


2


comes into contact with the second support part


15


and takes it with it.




In the stacking position of the table the two support parts


14


and


15


lie approximately parallel to one another and in the extension of the beam


12


. However, within the scope of the invention it is also conceivable that the locking mechanism


25


is constructed as a simple, optionally damped stop on which the extended second support part


15


rests and is held by the spring (not shown). The unlocking mechanism could then be configured in the manner described above, so that it simply has the function of entraining the second support part


15


in order to facilitate pivoting of the table top.




The table legs


18


are constricted as vertical supporting struts which have in their base region crossbars


16


which are supported on the floor by way of feet or castors


17


. In this case the crossbars


16


are disposed outside the pivoting range of the table top


10


, i.e. the lower edge


10


.


1


of the folded-down table top ends above the crossbars


16


, as shown in FIG.


17


.




The crossbars are constructed so as to be substantially horizontal, i.e. transverse with respect to the table legs


18


. In the illustrated embodiment the table has two legs which are each disposed at one end of the beam


12


.





FIG. 12

shows that in the working position of the table top


10


the crossbars


16


of the table legs


18


extend parallel to one another and in the direction of the depth of the table. In the stacking position shown in

FIGS. 17 and 18

it can be seen that the crossbars are at an angle due to the movement relative to one another by the support parts


14


. Thus each crossbar is for example at an angle of approximately 45° to the table top.




Due to this angular position the table can also still stand by itself with the table top


10


folded down, without this making more stowage room necessary when a plurality of tables are stacked in one another. In the top view according to

FIG. 18

the obliquely positioned crossbars doe project beyond the table top, but nevertheless tables which are stacked in one another can be stacked in one another so that they butt directly against one another.




The various embodiments of the table which are described above are distinguished by the fact that they can be brought from the working position into the stacking position and vice verse without problems by one person, since due to the coupling means a synchronised turning of the table legs with crossbars is effected when the table top is being pivoted. In combination with the facility for the table to stand by itself with the table top folded down, a further simplification is provided. If the tables also have castors, then even in the case of relatively large dimensions the tables can be closed or folded tip and moved easily by one person.
