J. J. LYTH FOLDING IRONING BOARD, TABLE, SEAT, AND THE LIKE Filed Dec. 13
. Wren/0r Patented June .24, 1930 UNITED STATES JOHN J. YLYTH, or VALLEYFIELD, QUE-BEG, CANADA FOLDING IRONING BOAR-D, TABLE, SEAT, THE LIKE Application filed December 13, 1926. Serial No. 154,589.
This invention relates to improvements in ironing boards, shelves, tables, seats, bunks and other articles which are normally used in horizontal position and the primary object of the invention is to provide means for 'swingingly supporting such articles (hereinafter all included in the generic term swinging member) without the use of legs extending tothe floor and in such. manner that they may be moved to and releasably retained in an inoperative vertical position preferably within a V cabinet.- Subsidiary objects are the provision of :-springs to largely or wholly support the weight of the swinging members during movement to and from operative position and to hold the swlnging members 1n inoperative position;
means to releasably lock the swinging members in operative position against the action of the springs; and supporting means arranged to directly support the swinging members without reliance upon fastening means. Various other objects and the advantages of the invention may be ascertained from the following description, which discloses the invention as applied to or embodied in a cabinet ironing board.
Briefly,the invention resides in providing .anironing board or other swinging member as aforesaid hinged at one end to the lower part of the back of a cabinet or other suitable vertically disposed base and pivotally connected adjacent the hinged end to the lower ends of links,.tl1e upper ends of which are connected by a yoke running in guides secured to the cabinet back and connected to one or more springs arranged to assist in lifting the board or other swinging mem-,
her into the cabinet.
In the accompanying drawings which illustrate theembodiment of the invention in an ironing board but to which embodiment or to the details of which the invention is not confined g I Fig. 1 is a side elevation of the ironing board in operative position, one side of the cabinet being cut away to expose the board supporting means andthe cabinet door being open.
is a front elevation of the cabinet with the door removed ancb the ironing board in operative position.
vReferring more particularly to the drawings, 11 designates a suitably proportioned base, which may be a simple board but is preferably the. back of a shallow cabinet 12 having a door 13. The base is designed to be rigidly secured flatwise and in upright position toa wall either as a removable attachment or asabuilt-in portion of th wall.
A pair of guides 14 exactly similar except that they are right and left hand, are dis posed in substantial parallelism and'firm'ly secured to the base near the vertical edges thereof. The guides are preferably each formed with two flanges 15 and 16 arranged at right angles, the flanges 15 being secured to the base and thevfianges 16being provided at their lower ends and at intermediate points with apertured projections 17 and 18 respectively. The apertures of the lower projections are circular as shown, while the apertures of the upper projections are slots 19 arranged substantially horizontally. The upper part of each guide flangelG- is provided with a longitudinal slot 20 which, at
its lower end, opens into the slot 19.
An ironing board 21 of suitable shape and of a width to pass easily between the guides 14 is provided on its upper surface 22 at one end with a transversely disposed cross piece or batten 23 attached thereto and terminating in trunnion portions 24 journalled in the apertures of the guide projections 17. A short distance from the batten 28 the board is provided on its lower surface with a similar batten 25 terminating in trunnions 26.
A pair of links 27 are provided, one on each side of the board, preferably outside the guide flanges 16, and are pivotally mounted at their lower ends on the trunnions 26 of the batten 25. The upper ends of the links are pivotallymounted 'on the ends of a rod 28 which passes through the slots of both (guides and isfreely 'slidable'therein, from the upper ends to the outerends of the slots equivalent thereof, serves to transmit to the 19 and vice versa; This member 28, or any I weight of the board and any downward pressure thereon. One or more helical springs 29 of suitable length are connected in tension between the links 27 and anchorages 80, preferably through the medium of the rod 28. The anchorages are of any suitable form and are attachedto the base a suitable distance above the guides. These anchorages are preferably in the nature of hooks with flanges of appreciable area for abutment against the base llfasshown. i i I The ends of the trunnions and rod 28 may be provided with any suitable fastening means, such as cotter pins 31, to maintain them in operative relation with the other elements of the structure. I
When not in use, the ironing board lies close to the base as shown in broken lines, Figure 1, and is'held in this position by the sp ngs Oper ng r ug the r62 2 ks 27 and batten 25. It will be noted that in this position the board supporting trunnions a d, the sp i g a hb ese ie n a P a b n the bo d and'bas hi e 'trunnions 26, to'which the springs are con.-
nected, lie on opposite or outer sides of the b a d, s he boa t nds o, a t s ppe end a ns h b se an n Po t to be retained upright by the action of gravy- V ry little sp ion s equi ed to hold the oa ag n ac d nt d splac ment. i
An iron stand 32 of suitable form may be secured to the upper surface of the board between the battens 23 and 25, The clothing of the board will extend from the free end approximately to'the batten 25.
When the board is to be used, it is moved ma a ly oim he ght PO itiQn to, t e horizontal position illustrated in full lines. Downward'movement ofthe board is communicated through the'links the rod 28, thereby elongating and tensioning the springs. In the final part of the downward movement, the links draw the rod 28 outwardly through the slots 19, which act to lock the rod,-links and board againstbeing drawn upwardly by the springs.
To'return the board to vertical position, upward movement is manually initiated so that the links drive the rod back through the slots 19 into the slots 20, whereupon the springs lift or assist in lifting the board. P t -sta ly the s r n s. ar of -suc n t t at hey ar a m st l ix d when th board is, folded up, thereby renderingi-nitiation of the dow wa ov m very sy e d. of suchstrengththat the tension increase due toelon gatidniis; equal to or slightly greater than theload increase due, to thejoutward swing "of the board. "Under these conditions the hoard will not fall and equally will not sla up whenthe upward 'inoveulent has been initiatedp departure, w th n reason," from the preferred conditions entails only effort to move or restrain movement of the board.
hen in use the board is supported entirely from one end, leaving the opposite end free for passage thereover of tubular articles. When the board is loaded beyond the batten 25, it presses down on the batten 25 which is beneath it and upwardly on the batten 23 which is above it, so that the load is received and sustained directly by the battens and is not transmitted through screws or the like securing the battens to the board. Also the links 27 are in tension. This arrangement ensures the maximum of strength, rigidity and durability with a cabinet of minimum size and supporting means of light and inexpensive construction which does not interfere with the working surface of the board nor with the space beneath and which is inconspicuous and not unsightly when seen.
While the preferred construction of one embodiment has been disclosed, it will be understood that the invention is not confined thereto and that all such changes may be made in size, shape and construction as fall within the scope of the appended claims.
Having thus described my invention, what I claim V 7' 1. folding structure comprising a vertically disposed base, supports secured to the base having L-shaped slots therein including vertically disposed long portions and horizcntally'disposed short portions extending away from the lease, a swinging member hingedly mounted at one end on the base below the slots of the supports and angularly movable relatively to the supports and base, links pivotally connected their lower ends to the swinging member acent the pivoted end thereof, a rod slida ble in the support slots and connected at its ends to the upper ends of the links, and a tensioned spring connected with the links and with thebase at a point above the supports,"to exert lifting effort on the swinging member, said rod serving when in the horizontal slot portions to hold the swinging member against the lifting effort of the spring.
