The present invention is directed to improvements in convertible furniture.
The primary object of the invention is to provide an article of'furniture so constructed that a single unit may be used such as an arm chair, or a pair of units may be connected to provide what is commonly termed a sofa .or love seat.
Another object of the invention is to provide novel means whereby the members forming the arm rests can be easily and quickly attached to or removed from engagement with the main chair body.
Still another object of the invention is to pro- 2 Claims. (01. 155-196):
vide an article of furniture wherein upon re- 1 moval of an arm rest a chair of like formation or second chair may be detachably connected therewith to produce a sofa or love seat.
With these and other objects in view this invention resides in the novel features of construction, formation, and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in
Figure 1 is a perspective view showing the device as a single chair unit.
Figure 2 is a bottom plan view of an arm rest.
Figure 3 is a sectional view on line 3--3 of Figure 1.
Figure 4 is a fragmentary side elevation.
Figure 5 is a fragmentary side view showing one of the cover plates in position.
Figure 6 is a perspective view of a cover plate.
Figure 7 is a face view of the locking plate.
Figure 8 is a plan view of one of the buttons.
Figure 9 is a sectional view taken on line 9-9 of Figure 3.
Figure 10 is a, bottom plan view of sections united to form a sofa.
Figure 11 is a plan view of a rotary latch carried upon the bottom of a chair section.
Figure 12 is a similar view of a catch plate mounted on a second chair section.
Referring to the drawing, l designates generally a chair including a bottom frame 2, seat cushion 3, and a back 4, and detachably connected to the bottom frame 2 are arm rests 5 in the form of panels.
The bottom frame has formed therein front and rear recesses 6 traversed by rods 1-'|, adapted for detachable engagement in the hooks 88 of the locking plates 9, two of which being detachably connected with each arm rest 5.
The frames of the arm rests 5 have carried thereby screws |0-Hl engageable in slots l ll I of the plates 9, as clearly shown in Figure 3 of the drawing.
Mounted on.the screws [fi e-l0 are buttons lll I, said buttons being rotatable on the screws ID in order that they may be rotated to permit removal or replacement of the plate 9 in an obvious manner, as the' occasion may require.
Assuming it isfdesired to remove one .or .both arm rests frointhefmainfchair section, it is only necessary to. 1ift)thei]arinj,rests,' whereupon the hooks 8 of the plates 9'will disengage the rods When an arm rest is removed from the main chair section the recesses will naturally be uncovered and in order to conceal these recesses to eliminate an unsightly appearance, cover plates l2 are provided and have carried thereby spring clips [3 adapted to yieldably engage the rods 1-1, this being of course only necessary when an arm rest is removed.
As shown in Figure 10 a pair of main chair sections are in abutting relationship, at which time it will be of course understood that the arm rests have been removed from the facing sides of the main chair sections in order that the abutting chair section will thus provide a sofa or love seat.
In order to firmly connect a pair of main chair sections one of the sections is provided with a pivoted latch [4 adapted to detachably engage a keeper 15 on the adjacent main chair section.
From the foregoing it will be seen that if desired a chair may be used without arm rests, or with one or both, and that by removing arm rests from a pair of main chair sections a sofa can be formed, with or without end arm rests.
As shown in Figure 8, the buttons H are roughened, as at I6, so that when engaged with similarly roughened surfaces I! of the plates 9 accidental rotation of the buttons is eliminated. Owing to these roughened co-acting surfaces of the buttons and plates any danger of the buttons tearing loose when the chair is being moved or subjected to vibration from any cause whatsoever, is eliminated.
The plates 9 are at all times connected with the arm rests 5 with the slots ll confined within recesses I8, and owing to the presence of the slots I I the plates 9 may be adjusted vertically relative to the rods 1 in order that the hooks 8 may be adgusted to assure proper engagement with said ro s. i
It will be of course understood that the structure is such that it can be used in connection with studio lounges or the like.
What is claimed is:
1. Fastening means for detachably securing together a pair of abutting furniture elements comprising an upstanding fastening plate having a pair of closed longitudinal slots arranged in spaced relation inwardly of one end thereof adapted to be arranged in face to face abutting relation with respect to one of said furniture elements, an elongated button positioned transversely of each of said slots adjacent to and abutting the non-confronting face of said plate, a fastening velement: carried by each of said buttons and extendingslidably through theadjacent slot and adapted to be secured to said one of said furniture elements, and a pair of longitudinally spaced apart hooks positioned along the other end of said plate and each adapted toslidably and embracingly receive a fixed projecting pin carried by the other of said furniture elements.
