G. W. ALDEEN HINGESUPFORT Filed y 1929 Patented Dec. 29, 1931 UNITED STATES PATE NT 1 OFFICE GEDOR W. ALDEEN, OF ROCKFORD, ILLINOIS, ASSIGNOR 'IO AMERICAN CAB INET HARDWARE CORPORATION, OF ROCKFORD, ILLINOIS, A CORPORATION OF ILLINOIS HINGE SUPPORT Application filed. J'uly 5, 1929. Serial No. 376,12O.

This invention relates generally to a hinge support for furniture or the like and more particularly to a means for hinging fallboards or drop-covers of cabinets, desks,

5 radio cabinets, or the like, which are hinged about an axis lying along the upper front edge of the floor of the cabinet. p

The object of this invention is to provide a new and improvedhinge support for the fall,- board ofa cabinet in which the fall-board pivotsabout an axis lying along the upper front edge'of the floor of the cabinet, said hinge support comprising members which are ada ted to be mounted on the inner surface of t e side wall of the cabinet and upon the upper surface of the fall-board without necessitating the cutting of any mortise.

Another object of the, invention is to provide such a'hinge support, the parts of which may be made of sheet metal ajndhence are simple and inexpensive to manufacture. In pursuance of the above, I aim to pro;- vide a hinge support for thefall-board of a cabinet comprising a member adapted to be mountedon the innersur'face of the side wall of the cabinet and having a vertical slot cut therein, a second ,member adapted to be mounted. on the fall-board and providing an upwardly extending lug at each end carrya ing a pin, a link having a pin on. its upper end sliding in the slot in the first member and having its lower end pivotally connected to the pin at the inner end of the second member, a second link having one end pivotally connected to the lower end of the first member and extending outwardly along the fallboard and having a longitudinal slot adjacent its outer end inwhich the pin at the outer end of. the second member slides, and means pivotally connecting the two links together near the lower end'of the first link the inner end of the second link.

Other objects and advantages of my invention will be understood from the following detailed description thereof, taken in connection with the accompanying drawings, inwhich: f

Figure 1 isa section. through a cabinet showing the preferred form of my invention and in side elevation with the fall-board-in its open position. I

Fig. 2 is a fragmental plan view with the cabinet cover removed and the fall-board in open position. I

Fig. 3 is a section similar to that shown in F ig. 1 except that the fall-board is closed.

While the invention is susceptible of. various modifications and alternative construe: tions, Ihave shown in thedrawings and will herein describe in detail the preferred embodiment, but it is to beunderstood that I do. not thereby intend tolimit the invention to the specific form disclosed, but intend to cover all modifications and alternative constructions falling within the spiritand scope of the invention as expressed in the appended claims. v In the drawings, a cabinet or desk is shown for which this hinge support is suitable. The cabinet comprises a side wall 10, a floor 11, and a closure or a fall-board 12. The floor 11- and fall-board 12 have corresponding hinge support is illustrated, the other one being exactly similar but left-handed.

The hinge support illustrated herein comprises generally a member adapted to be mounted on the side wall 10 of the cabinet,

,another member adaptedto be mounted on the fall-board 12, and two links adapted to be attached to the fall-board and body of the cabinet by being'pivoted to one of the members and to the other-link andslidably connected with the other member. V T In the present instance a member 14, comprising afiat strip of metal, is adaptedto be 15. On the rearedge of the memberl i and adjacent the upper end thereof a portion of themetal is bent inwardly and thenforwardr secured to the inner surface of the side wall 10 1n a vertical position by means of screws ly to form a channel-shaped lug 25' andf'fla 7 vertical slot 24 is cut thereinfi second member 16, comprising a fiat stripof metal, is adapted to be secured'to the inner surface of the fall-board 12 by means of screws 17 I with its inner end adjacent the fall-board axis and extending outwardly at right angles therefrom. Two

lugs

21 and 33 are formed on the inner and outer ends respectively by bending a portion of metal on the outer edge of the member 16 upwardly, the lug 21 being provided with a pin 22 and the lug 33 with a pin 32. i

As mentioned above, my invention includes two links. One of these, the link 20, is provided with a pin 23 in its upper end which pin slides in the slot 24 cut in the lug 25, on the first member 14. The link 20 extends downwardly therefrom and has means for pivotally connecting its lower end to the .fallboard adjacent the inner edge thereof. In the present instance this means comprises the pin 22 on the lug 21' on the inner end of the member 16. A second'link 26 is pivotally connected at its inner end by means of a pin 27 to the side wall adjacent the fall-board axis, the pin 27 in the present instance being mounted on the lower end of the first member 14, and extends outwardly along the fall-board. Adjacent the outer end of the link 26 a longitudinal slot 31 is cut in which the pin 32 on the lug 33, formed on the outer end of the second member 16, slides. The two

links

20 and 26 are pivotally connected together near the lower. end of the first link 20 and the inner end of the second link 26 by means of a pin 30.

Vhen the fall-board is open, as shown in Fig. 1, the arrangement of the pivots is such that the fall-board is in a horizontal position flush with the floor of the cabinet. The pin 23 of the first link 20 is limited against further downward movement by the lower end of the slot 24:, and the pin 32 on the lug 33 is at the outer end of the slot 31 in the link 26, thus limiting further outward movement of the pin 32 caused by a downward movement of the fall-board 12. The link 26 further limits the opening of fall-board when the slots wear by having its lower side arranged to abut the second member 16.

It is to be noted that

pins

22, 27 and 30 form an equilateral parallelogram with the fall-board axis, and that

pins

27, 22 and 32 are horizontally aligned when the fall-board is open.

When the fall-board is closed, as is shown in Fig. 3, the two

links

20 and 26 fold together within the ChanneLshaped lug 25 with the link 26 lying between the link 20 and the first member 14. Also the pin 22 moves to a position coaxial with the pin 27.

It is apparent that I have provided a new and improved hinge support for the fallboard ofa cabinet in which the fall-board pivots about an axis lying along the upper front edge ofthefioor of the cabinet. It is also apparent that the parts of my hinge are adapted to be mounted on the surface of the side-wall body of the desk and is slidably connected at its outer end to the fall-board whereby the link extends horizontally along the fallboard when the latter is in fully open position, the'second link pivoted at its lower end to the rear portion of the first link and to the inner portion of the fall-board respectively, the second link being slidably connected at its upper end to the desk body, the pivots and sliding connections for said links being so arranged that the fall-board may swing about an axis that will maintain the upper rear edge of the open fall-board inclose proximity to the upper forward edge of the floor of the desk in all positions of the swinging movement of the fall-board, and the sliding connections being limited in the extent of their movement so that the fall-board will be prevented from swinging below a substantially horizontal plane.

2. A hinge support for mounting the fallboard of a desk or like article of furniture comprising, in combination, a pair of links, one of which is pivoted at its inner end to the body of the desk and is slidably connected at its outer end to the fall-board whereby the link extends horizontally along the fallboard when the latter is in fully open position, the second link being pivoted at its lower end to the rear portion of the first link and to the inner portion of the'fall-board re- '5 spectively, the second link being slidably connected at its upper end to the desk body, the pivots for said links being closely adjacent the rear edge of the upper surface of the fallboard to insure a movement of the fall-board about an axis substantially coincident with said rear edge.

3. A hinge support for the fall-board of a cabinet comprising, in combination, a first member adapted to be secured in a vertical position to the inner surface of the side wall of the cabinet adjacent the front edge thereof and comprising a flat strip of metal having a lug forming achannel with said strip, a second member adapted to be mounted on the upper surface of the fall-board adjacent the side edge thereof and comprising a flat strip of metal having a pair of relatively small lugs bent upwardly from the outer edge of said strip adjacent the res pcctive ends thereof, and a pair of links pivoted to each other, one of said links being pivotally attached to the lug and the inner endof the second member and slidably attached to the lug on the first member, the other of said 1,sss,351

links being pivotally attached to the lower end of the first member and slidably attached to the lug on the outer end of said second member, said links comprising fiat strips of metal which lie in substantially parallel planes and interfold in a compact arrangement within the channel of the first member when the fall-board is closed, and which lie close to and substantially along the respective member when the fall-board is open.

4. A hinge sup-port for the fall-board of a cabinet comprising, in combination, a pair of members constructed to be secured to the inner surface of the side wall of the cabinet and to the upper surface of the fall-board respectively, and a pair of links pivoted to each other, each link being pivoted to one of said members and slidably attached to the other of said members, said membersand said links comprising relatively long narrow fiat strips of metal, said cabinet member and said links interfolding with each other in a parallel arrangement when the fall-board is closed to occupy a space defined by the length of the longest strip, the width of the widest strip, and a depth substantially equal to the sum of their thicknesses, with the body member lying closely along said space.

5. A hinge support for the fall-board of a cabinet comprising, in combination, a pair of members and a pair of links, each of said links being pivotally attached to one of said members and to the other link and slidably attached to the other member, one of said members being constructed to be secured in a vertical position to the inner surface of the side wall of the cabinet adjacent the front edge thereof, and the other of said members being constructed to be secured to the upper surface of the fall-board along the side edge thereof, said members and said links folding into a non-divergent and compact arrangement within the cabinet and occupying a relatively small space adjacent to the corner formed by the side wall and fall-board when the latter is closed.

In testimony whereof, I have hereunto affixed my signature.
