Definitions
- This invention relates to desks.
- a desk of a kind which comprises a base-structure and a desk-top supported by the base-structure and which is convertible for use as a bed by movement of the desk-top relative to the base-structure, the desk-top when so moved being supported by the base-structure to extend substantially horizontally on legs from the base-structure for defining with it an elongate substantially-horizontal support-surface of the bed.
- a desk of this specified kind is characterised in that the legs are carried by the desk-top, and that the legs are carried by the desk-top in a folded condition for selective deployment in the support of the desk-top extending from the base-structure.
- the desk of the invention accordingly has two configurations in a first of which it has the form of, and is useable conventionally as, a desk, and in the second of which, following movement of the desk-top as aforesaid, is useable as a bed. Accordingly, the desk of the invention combines in the one item of furniture, the two functions of desk and bed, and can be readily converted from one to the other. The desk therefore offers the possibility of saving domestic space in the provision of desk- and bed- functions selectively.
- the desk-top may be pivotally mounted on the base-structure, and in this regard may be pivoted to a frame-member that is itself pivoted to the base-structure.
- the frame-member may extend substantially horizontally from the base-structure intermediate the base-structure and the desk-top as part of said support-surface when the desk is converted to a bed.
- the desk-top may be pivoted to the base-structure for lifting up and over to extend upside down substantially horizontally from the base-structure.
- the upper work-surface of the desk-top may be backed by a sheet of plastics foam such that said sheet is uppermost when the desk is converted to a bed.
- the base-structure may be a pedestal-supported panel having an upper surface of plastics foam, and the desk may include means for selective adjustment of the height of the base-structure.
- the desk of the invention may include provision for accommodating and retaining a mattress or futon for use with the bed.
- the base-structure for supporting the top of the desk may include interconnected recesses for accommodating and retaining a mattress or futon within the desk, the recesses extending within the desk from a first recess covered by the desk-top into a second recess located behind an upright wall of the base-structure.
- the desk-top when moved relative to the base-structure for conversion of the desk to a bed may uncover the first recess to enable release of the mattress or futon from within the second recess for deployment on the support-surface.
- the substantially-horizontal top 1 of the desk is supported on a base or carcass 2 that includes two drawer-units 3.
- the units 3 are spaced laterally from one another to define a well 4 to accommodate the desk-user's legs when he/she is sitting up to the desk.
- the height of the well 4 is defined by horizontal slatting 5 of the carcass 2.
- the slatting 5, which extends across the full width of the desk over the units 3, is spaced below the desk-top 1 to leave a recess 6 in the carcass 2, covered by the top 1.
- the horizontal recess 6 is contiguous with, so as to extend into, a vertical recess 7 that throughout the full width of the desk is defined in the carcass 2 between an upright back wall 8 of the desk and an upright inner wall 9.
- the recesses 6 and 7 combine to provide accommodation and support for a futon 10 concealed within the desk.
- the futon 10 is accommodated in a folded condition within the desk. Approximately two thirds of the futon-length is received folded in half as portions 11 and 12 standing upright within the recess 7, whereas the remaining portion 13 extends folded down substantially horizontally from the portion 12 into the recess 6.
- the futon-portion 13 lies under the desk-top 1 on the slatting 14 of a partially-slatted frame 15 that rests within the recess 6 on the slatting 5.
- the frame 15, which is pivoted on either side to the desk-top 1 towards the back of the desk, is itself pivoted to the carcass 2 at the front of the desk.
- the desk When the desk has the normal configuration shown in Figures 1 and 2, it is useable as, and provides the conventional facilities of, a knee-hole desk.
- the configuration of the desk can be changed to convert it into a bed simply by releasing a lock (not shown) that secures the top 1 covering the carcass 2 and lifting the top 1 up from the carcass 2 about the pivoting with the frame 15.
- a lock (not shown) that secures the top 1 covering the carcass 2 and lifting the top 1 up from the carcass 2 about the pivoting with the frame 15.
- This allows the futon-portion 13 to rise from the recess 6 and be freed from within the frame 15 as the top 1 is pulled inclined upwards and forwards in the direction from back to front of the desk.
- the desk-top 1 is pulled horizontally in the same direction from back to front of the desk, causing it to rise progressively upwardly and then downwardly relative to the carcass 2 as the frame 15 pivots on the carcass 2, in the manner illustrated in broken line in Figure 3.
- Continuation of the movement brings the top 1 extended on the frame 15 from the front of the desk, to project substantially horizontally level with the frame 15, as illustrated in full line in Figure 3.
- the frame 15 In the normal configuration of the desk, the frame 15 lies upside-down on top of the slatting 5, but pivots up from there about the front of the desk as the top 1 is pulled forward. When, with the further pulling out of the top 1, the frame 15 pivots down into alignment with the slatting 5, the frame 15 can turn no further and locks in the horizontal attitude. The top 1 is then brought into alignment with the frame 15 to be locked projecting horizontally. In this condition, two legs 16 which are normally stowed folded up under the front edge of the top 1, are pivoted down to give front-end support to the top 1. The desk is now in the bed-configuration.
- the futon 10 (not shown in Figures 3 and 4) can now be pulled by the portion 13 to withdraw the portions 11 and 12 from the recess 7 and deploy it lengthwise on the elongate, substantially-horizontal surface constituted by the aligned slatting 5 and 14 and desk-top 1.
- a hinged panel 17 of the back wall 8 is pivoted down over the recess 7 so as to allow the full available bed-length on the carcass 2 to be used for support of the futon 10.
- the desk When the desk is in the bed-configuration it can be readily returned to the desk-configuration by folding up the legs 16, re-stowing the futon-portions 11 and 12 within the recess 7, and pushing the top 1 upwardly after it has been unlocked from alignment with the frame 15.
- the futon-part 13 can be inserted into the recess 6 and the top 1 closed onto the carcass 2 and locked in place to restore the desk to its normal, compact configuration.
- the desk has a panel-top 21 which is pivoted at the front to a base-panel 22 that is slightly bowed in its thickness from front to back and is supported by twin pedestals 23.
- the top 21 has a frame-surround 24 with an upper work-surface 25 that is backed by a sheet 26 of medium-density plastics-foam.
- a sheet 27 of the same foam provides the upper surface of the base-panel 22.
- a flat support surface for the sheet 27 is provided within a frame-surround 28 of the base-panel 22 by slabs 29 of high-density plastics-foam that bear tightly against one another over two strengthening cross-rails 30 of the frame-surround 28.
- the desk is prepared for conversion from its normal desk-configuration shown in Figure 5, to its configuration as a bed, by first swinging two legs 31 up from their folded condition along the back of the frame-surround 28 (as illustrated in broken line for one of them, in Figure 5), and reducing its height.
- the pedestals 23 are of telescopic structure and each incorporate a rise-and-fall mechanism 32 that when freed allows the height of the base-panel 22 to be adjusted up or down at will simply by exerting a gentle force, upward or downward, on it.
- Each mechanism 32 includes a constant-torque spiral spring for counter-balancing purposes and a latch for locking the base-panel 22 at the height to which it is adjusted.
- the latches of the two mechanisms 32 are coupled, for example by cable, to a control (not shown) at the back of the desk, by which they can be withdrawn to free the pedestals 23 to telescope and then re-engaged to lock them at the adjusted height.
- the top 21 is now unlatched from the back of the base-panel 22 and lifted up and over pivotally to bring the legs 31 deployed from the upside-down top 21, down to ground. With the height of the base-panel 22 reduced using the mechanism 32, the top 21 extends horizontally from it so that the sheets 26 and 27 are level with one another to provide a suitable flat, bed support-surface.
- Two hinged headrests 33 for the bed are normally folded over to lie beneath the top 21 in the desk-configuration, but once the bed has been opened out as illustrated in Figure 7, they can be folded up to increase the effective length of the bed.
- the desk can be readily returned to its normal configuration as a desk, by folding over the headrests 33 and then turning the top 21 back over the base-panel 22 and latching it closed.
- the mechanisms 32 are operated to release the telescopic pedestals 23 for return and locking of the desk-top 21 at an appropriate height, and then tne legs 31 are folded down to complete the return.
