Abstract
The table has a base structure 1 which is pivotally coupled via a connecting member 15 and an intermediate member 16 to a top 2. By standing the base on either of two adjacent sides and pivoting the top by the connecting member 15, the top can be rested on the base at two different heights. The top is formed by two hinged leaves 31 and 32, and at either height the top can be swivelled on the intermediate member 16 and opened out to provide an extended surface area. In the higher position the top can also be fixed in an inclined position for use as a drawing board.
Description
- This invention relates to tables, and particularly those including means by which they can be adjusted in height.
- GB 598 783 discloses a table comprising a base structure which is arranged to be stood with either of two adjacent substantially perpendicular surfaces uppermost such that in the two positions the two surfaces will be at two different heights, a connecting structure which is pivotally coupled to the base structure for rotation about a first axis which extends substantially parallel with the junction between the said surfaces, and a table top which is coupled to the connecting structure to rest on either of the two surfaces. The top is slidably connected to the connecting structure, but the use of a slidable connection is generally undesirable since it can easily result in jamming.
- An aim of this present invention is to provide a table which can easily be manipulated to a range of configurations and which is also inexpensive to manufacture.
- The present invention proposes that the table top is pivotally coupled to the connecting structure for rotation about a second axis which is substantially parallel to, but spaced from, the first axis. The slidable connection is thereby eliminated providing a potentially smoother action.
- It is further proposed that the base structure may be provided with locating means for positively locating an edge of the top which extends substantially parallel to the first and second axes so as to support the top in an inclined position.
- The top may further include first and second sections which are hinged together at a pair of common edges thereof, the first section being pivotally coupled to the connecting structure via an intermediate structure which is in turn pivotally coupled to the first section of the top to permit the top to swivel about a third axis extending substantially perpendicular to the first section and offset from the centre thereof such that when the two sections of the top are opened out into substantially coplanar positions the top can be pivoted about the third axis to be supported in its approximate centre by the base structure.
- The invention is exemplified in the accompanying drawings, in which:
- Figure 1 is a perspective view of a table of the invention shown in a suitable configuration to reveal the underside of the table top,
- Figure 2 is a perspective view of a linking structure which joins the top and base of the table,
- Figure 3 is a section through the linking structure taken transverse to its pivot axes,
- Figure 4 is a perspective view of the table in a small, low level configuration,
- Figure 5 is a perspective view of the table during movement from the configuration of Fig. 4 to an extended configuration,
- Figure 6 is a perspective view of the table in the extended configuration,
- Figure 7 is a perspective view of the table in a small, high level configuration,
- Figure 8 is a perspective view of the table during amovement from the configuration of Fig. 7 to an extended configuration,
- Figure 9 is a perspective view of the table in the extended, high level configuration, and
- Figure 10 is a perspective view of the table in a drawing board configuration.
- Referring firstly to Fig. 1, the table includes a
base structure 1 which is connected to atop 2 via a linkingstructure 3. - The
base 1 comprises four substantially parallel legs 4-7 which are fixed to a cross-shaped frame 8. The legs are all of triangular cross section and have laterally projectingtriangular feet 9 secured to one end. The opposite ends of an adjacent pair oflegs triangular bearing plates 10. The other two legs, 4 and 5, have pivot blocks 11 secured to their inner faces at the opposite ends to thefeet 9, these blocks 11 providing thelegs faces 12. - The linking
structure 3 is shown in more detail in Fig.s 2 and 3 and comprises a pair ofU-members cross piece 17 having a pair of substantiallyparallel arms pivots arms cross piece 17 of thelarger U-member 15 extends between theinternal faces 12 of the blocks 11 to which it is coupled by axially alignedpivots cross piece 17 of thesmaller U-member 16 contains afurther pivot pin 24 which extends substantially perpendicular to the general plane of the U-member and is offset from the longitudinal centre of therespective cross piece 17. One end of the pin is secured to anattachment plate 25 which rotates against an adjacent side face of thecross piece 17 whereas the opposite end of the pin is threaded to receive alocking nut 26 which is recessed into the opposite side face of thecross piece 17. - Referring back to Fig. 1, the
table top 3 comprises a pair of substantiallyidentical leaves common edges 33. Theattachment plate 24 is secured in an off-centre position to the underside of one of theleaves 31, and an L-shaped stop 34 is also secured to the underside of the same leaf to co-operate with thecross piece 17 of thesmaller U-member 16. - The underside of
leaf 31 further has fourrecesses 35 located in its four corners, two of therecesses 35a being triangular to receive thebearing plates 10 and the other two 35b being square to receive the blocks 11 together with the ends of thelegs feet 9 stand flat on the ground and the top is in a folded configuration as shown in Fig. 4, the top is positively located to prevent rotation about the axis ofpivot pin 24. In this configuration the twoU-members cross piece 17 of the larger U-member 15 being received in a channel 36 (Fig. 1) joining the twosquare recesses 35b. - Whilst in this low configuration the top can be extended by lifting it slightly to disengage the legs from the
recesses 35 and rotating it about the axis ofpivot pin 24 as shown in Fig 5 until thehinged edge 33 lies above the centre of thebase structure 1. This position is positively determined by engagement of thestop 34 with thecross member 17 of thesmaller U-member 16. The twoleaves - To increase the height of the table, the folded
leaves pivoted legs legs upper legs pivots cross pieces 17 lying substantially on opposite sides of thepivots hinged edge 33 lies above the centre of thebase structure 1, this position again being determined by engagement of thestop 34 with thecross member 17 of thesmaller U-member 16. The leaves can then be unfolded to the extended position shown in Fig. 9. The leaves can be returned to the folded configuration by the reverse sequence of movements. - From the high configuration of Fig. 7 the table can also be manipulated into a drawing board configuration as shown in Fig. 10. The folded leaves are again lifted so that the
larger U-member 15 rotates about the axes ofpivots feet 9 which are secured to thelegs top 2 in this position a pair of wire stays 41, 42 may be provided. Each stay comprises astraight middle portion 43 with itsends end 44 is inserted into a respectivetriangular recess 35a whilst theopposite end 45 is inserted intoholes 46 provided at the roots ofarms - It will be appreciated that the
base structure 1 could take various forms and that the particular arrangement shown in the drawings is purely illustrative.
