No. 703,054, Dec. 16, 1957. This application Dec. 21, 1959, Ser. No. 861,422
' red 1 Claim. (Cl. 155-124) The present invention relates to a combination chairdesk structure primarily intended for use in classrooms.
This is a continuation of our co-pending application, Serial No. 703,054, filed December 16, 1957, now abandoned.
The primary objects of the invention are to provide a combination chair-desk structure in which the desk top and the chair seat and back are supported on a frame fabricated of bent metal tubing; to provide such a structure in which the supporting frame includes front legs depending from the desk top and rear legs depending from the chair seat; to provide such a structure in which the desk top may be positioned either level or at a rearward-downward inclination; to provide such a structure in which a novel book storage rack is provided beneath the chair seat, and in general to provide such a combination chair desk structure which is sturdy in construction, reasonably economical in manufacture and attractive in appearance.
An illustrative embodiment of the invention is shown in the accompanying drawings, wherein:
Figure 1 is a perspective view of the new combination chair-desk;
Figure 2 is a central, longitudinal, vertical sectional view thereof, the plane of section being indicated by the line 2-2 of Figure 3, and the desk top being shown in level position in full lines and in rearwardly-downwardly inclined position in dotted lines;
Figure 3 is a front elevational view of the combination chair-desk, the chair seat being shown fragmentan'ly;
Figure 4 is a bottom plan view thereof, the underseat bookrack being omitted in this view;
Figure 5 is an enlarged, fragmentary, central vertical sectional view through the desk top and parts adjacent thereto, the top being here shown in rearwardly-downwardly inclined position;
Figure 6 is a similar sectional view showing the desk top in level position; and
Figure 7 is a fragmentary vertical sectional view of parts thereof taken on line 7-7 of Figure 6.
Referring now in detail to these drawings the combination chair-desk there shown comprises generally a desk top 10, a chair seat 11 and chair back 12, an underseat bookrack 13 and a supporting frame for the aforesaid parts which is generally designated 14. The desk top is positioned above and forwardly of the chair seat 11.
The supporting frame 14 comprises a pair of front frame elements 15, a pair of rear frame elements 16 and an intermediate frame element 17, all of said elements being fabricated of bent metal tubing. The front frame elements have top supporting portions 18 extending forwardly-rearwardly beneath the desk top 10 and secured thereto in laterally spaced relation, and downwardly tapered front leg portions 19 depending from the forward ends of said top-supporting portions 18.
The rear frame elements 16 have seat-supporting por- 2,979,117 Patented Apr. 11, 1961 ice tions 20 extending forwardly-rearwardly beneath the chair seat 11 and secured thereto in laterally spaced relation as by means of rivets 21, and downwardly tapered rear leg portions 22 depending from the rearward ends of said seat-supporting portions 20.
The intermediate frame element 17 has an upper forward arm 23 extending transversely beneath the rear part of the desk top 10 and secured as by welding to the rearward ends of the front frame elements top-supporting portions 18. This intermediate frame element 17 also has a lower rearward arm 24 extending transversely beneath the front part of the chair seat 11 and secured as by welding to the forward ends of the rear frame ele ments seat-supporting portions 20. A connecting por tion 25 of the intermediate frame element 17 connects the ends of said elements arms 23 and 24 at one sid of the chair-desk structure.
The connections between the desk top 10 and the supporting frame 14 are such that the top may be positioned either level or at a forward-upward inclination. To this end the desk top 10 is pivotally mounted on the upper forward arm 23 of the intermediate frame element 17 by means of metal straps 26 extending around said arm 23 and secured to the rearward underside of the desk top 10 by means of screws 27. (See Figures 5-7.) Brackets 28 are secured to the forward underside of the desk top by means of screws 29, each bracket having an upper aperture 30 and a lower aperture 31 adapted to receive a bolt 32 passing therethrough and through the adjacent top-support 18 and provided with a nut 33. It will be seen that the desk top can be positioned level by passing the bolts 32 through the upper apertures 30 of the brackets 28, or positioned at a forward-upward inclination by passing the bolts 32 through the lower apertures 31 of the brackets 28.
The underseat bookrack 13 is fabricated of metal rod stock. It comprises a length of rod stock bent to form a pair of L-shaped side members 34 secured at their upper front to the arm 24 of the intermediate frame member 17 as by welding and secured at their lower rear to the rear legs 22 likewise as by welding. These L-shapcd side members 34 are connected in the rear by the honzontal medial portion 35 of the same piece of rod stock. Cross-pieces 36 of rod stock are secured as by welding to the opposite side members 34 to form the bottom of the bookrack.
The chair back 12 is secured to the structure by means of a pair of laterally spaced back supports 37 of metal rod or tubing. These back supports 37 have lower horizontal portions 38 secured as by welding to the seatsupporting portions 20 of the rear frame elements 16. From these welded connections the back supports 37 extend rearwardly of the seat 11 and thence upwardly to form vertical portions 39 on the upper ends of which the chair back 12 is pivotally or otherwise mounted.
' It will thus be seen that the invention provides a sturdy, economical and attractive combination chair-desk structure, and while but one specific embodiment of the invention has been herein shown and described it will be understood that numerous details may be altered or omitted without departing from the spirit of the invention as defined by the following claim.
We claim:
In a combination chair-desk structure: a pair of tubular front frame elements having horizontal, forwardlyrearwardly extending top-supporting portions and front leg portions depending from the forward ends of said top-supporting portions; a pair of tubular rear frame elements having forwardly-rearwardly extending seatsupporting portions below and rearwardly of the top supporting portions of the front frame elements and having rear leg portions depending from the rearward ends of said seat-supporting portions; an intermediate tubular frame element having a transversely extending upper forward arm connected to the rearward ends of the front frame elements top-supporting portions, a transversely extending lower rearward arm connected to the forward ends of the rear frame elements seat-supporting portions, and a connecting portion connecting the ends of said arms at one side of the chair-desk structure; a chair seat mounted on the seat-supporting portions of the rear frame elements; a desk top having straps secured to and depending from the rearward underside of the desk top, said straps extending around the upper forward arm of said intermediate frame member whereby the desk top is pivotally mounted on said arm for swinging movement between a horizontal position resting on the frontframe elements top-supporting portions and a forwardly-upwardly inclined position; brackets depending from the forward underside of the desk top alongside the front frame elements top-supporting 4 portions; and means connecting said brackets to said topsupporting portions at selected elevations whereby the desk top may be secured in horizontal position or in a position of forward-upward inclination.
