Legless Ironing Board

Abstract

A compact, legless ironing board suitable for use by travelers and provided with adjustable means at its heel end detachably engageable over the shanks of door knobs to hold the heel end of the board clamped crosswise of the edge of an open door for emergency ironing and pressing tasks. A chucking device is insertable beneath the door corner and is effective to wedge the door against hinging movement in either direction until released.

Description

This invention relates to ironing boards and more particularly to a compact, legless board for use by travelers and occupants of trailers and detachably mountable outstretched from the edge of an open door while anchored to the shanks of the door knob.

Travelers and occupants of trailers and Pullman type compact living quarters have need for a small legless ironing board readily stowable in a minimum of space and adapted to be carried in hand luggage. Various proposals for legless ironing boards have been made heretofore but these designs leave much to be desired and are unsatisfactory for a number of reasons. Some of these proposals make use of the knob on any convenient room door. However, all prior designs of this type are arranged to have the heel end of the board flush against one face of the door and held in position thereagainst by various clamping devices engageable with the door knob. Such designs not only are likely to damage the finish of the door surface, but impose excessive stresses on the door knob not infrequently causing damage or failure of the knob. In particular, such anchoring devices place the door knob and its supporting shank in tension and result in shearing the set screws used to hold the knob assembled to the latch operating shank. Furthermore, the surface contours of door faces vary widely, some being flat and lying in a common surface and others being designed with panel inserts of widely varying configurations. Furthermore, the door casing finishing structure normally projects beyond the surface of the door and interferes with if it does not prevent proper assembly of the board to the door knob.

The foregoing and other serious shortcomings of prior legless ironing board designs are avoided by the present invention. To this end, the simple legless board herein disclosed is designed for rigid securement with its notched heel end embracing the edge of an open door and projecting forwardly in the general plane of the door. The heel end of the board is equipped with adjustable hook means lying closely against either side of the notch and these readily engage over the shank of the door knob at its base ends so as to place this heavy shank structure in shear and avoid placing the set screws or other assembly fasteners for the door knob under stress of any kind. A folding bracket hinged longitudinally of the lower side of the heel end bears against the edge of the door when extended and supplements the hook means and notch in supporting the board firmly in a horizontal operating position. A simple positive action chucking device is insertable beneath the lower corner of the door and cooperates with the floor surface in anchoring the door in any desired open position so long as the board is mounted thereon.

Accordingly, it is a primary object of the present invention to provide a simple lightweight legless ironing board having numerous novel features.

Another object of the invention is the provision of a compact, legless ironing board readily attached to and detached from a room door knob while the door is in open position.

Another object of the invention is the provision of a legless ironing board adapted to be assembled astride the edge of an open door and to be held in position thereon by hook means engaging over the shanks of the door knobs.

Another object of the invention is the provision of a legless ironing board supportable from the door knob of an open door and held rigidly in position projecting outwardly from the edge of the door while the latter is wedged in a selected open position by chucking means inserted therebeneath.

These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawing to which they relate.

Referring now to the drawing in which a preferred embodiment of the invention is illustrated:

FIG. 1 is a perspective view showing a preferred embodiment of the ironing board assembled to the edge of an open door;

FIG. 2 is a fragmentary perspective view on an enlarged scale from the heel end of the board before assembly to the door;

FIG. 3 is a fragmentary cross sectional view on an enlarged scale taken along line 3--3 on FIG. 1;

FIG. 4 is a fragmentary end view on an enlarged scale taken crosswise of the heel end of the board and showing by dot and dash line the position of the bracket when folded for storage;

FIG. 5 is an enlarged fragmentary cross-sectional view taken along line 5--5 on FIG. 2; and

FIG. 6 is a perspective view of the chucking device per se.

Referring initially, more particularly to FIG. 1, there is shown an illustrative embodiment of the invention legless ironing board, designated generally 10, comprising an elongated flat and rigid main body 11 having a rounded toe end 12 and a broad heel end 13. The latter is notched at 14 so as to snugly embrace the edge of a conventional room door 15. Notch 14 as well as the heel end proper is preferably covered with a thick resilient guard strip 16 effective to accomodate a reasonable variation in the thickness of doors while resisting play between the door and the board when in use.

Adjustably supported in the heel of the board closely adjacent the opposite edges of notch 14 are a pair of J-shaped hooks 18,18 having threaded stems 19. These stems have a loose fit within wells 20 projecting through the heel end of the board into mating engagement with threaded anchor means 21 fixed within recesses 22 of the main body of the board. The hooked ends of members 18 are preferably coated with plastic or elastomer to avoid scarring any object with which they come in contact and more particularly the door surface or hardware. The conventional door knobs 25 are held assembled to the door in the usual manner and have a snug telescopic fit over the opposite ends of the non-circular latch operating bar 26.

It is important that the hooks 18 hold the board firmly seated against the bottom of notch 14. To this end, hooks 18 are readily rotated in either direction as necessary for their outer ends to project the requisite distance to have a firm press fit over the shanks of the door knobs in the manner made clear by FIGS. 3 and 5. A proper adjustment is readily determined by trial and error and, once made for a particular door, need not be changed.

Supplementing hooks 18 in anchoring the board to the door edge is a bracket here shown as generally triangular in form with its longer horizontal edge hinged to the central underside of the board by a piano type hinge 31 (FIG. 4). The upright vertical edge 32 of the bracket is positioned close to the door edge and in the plane of the bottom of notch 14. The lower corner of bracket 30 is provided with a pivoting U-shaped clip 35 rotatably mounted on a screw 36. Clip 35 conforms in shape and size with notch 14 which it underlies in order to embrace the edge of the door and hold the bracket firmly in its extended position. Accordingly, it will be apparent that bracket 30 and clip 35 cooperate with hooks 18 in stabilizing and holding the board supported in a proper horizontal operating position. When not in use, clip 35 is rotatable so as to lie generally in the plane of bracket 30 for compact storage as is clearly evident in the dotted line showing of the bracket in FIG. 4.

A useful auxiliary accessory comprises a chucking block 40 which is insertable beneath the lower outer corner of the door to clamp the door rigidly in a desired open position while the ironing board is mounted thereon. In a preferred form, chucking device 40 comprises a pair of double wedge-shaped blocks 41,41 interconnected by a flexible resilient plate 42. Thus it will be observed that the upper faces of the wedges 41 slope in two directions, namely toward their forward ends as well as transversely and toward one another beneath the connecting plate 42. Prior to insertion the upper faces of the wedges lie in a common plane with the underside of the flexible plate 42. However, when forcibly inserted beneath the outer corner of the door, plate 42 is forcibly bowed downwardly thereby forcing wedge members 41 into firm gripping relation with the floor so that they are equally effective in preventing swinging movement of the door in either direction.

The mode of use and assembly of the board to the door will be readily apparent from the foregoing detailed description. It is merely necessary to adjust the projection of hooks 18 from the heel of the board if this be necessary. Any necessary adjustment having been made, the operator unfolds bracket 30 and pivots clip 35 to its proper position as shown in FIG. 2. The board is then placed astride the edge of the open door while held horizontally and in a plane above the door knob. With the clip 35 and notch 14 embracing the door the operator lowers the board until the slightly resilient hooks 18 are pressed over and firmly engaged with the shanks of the door knobs. This operation is usually performed after the chucking device 40 has been inserted under the corner of the door so there is no risk of the door swinging while the board is being installed. The operator then proceeds to use the board in the normal manner.

After the ironing operation is finished, the board is removed by lifting it bodily upwardly until hooks 18 are disengaged from the door knob whereupon it is pulled away from the door and the bracket is folded against the underside of the board for storage until again needed.

While the particular legless ironing board herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiments of the invention and that no limitations are intended to the detail of construction or design herein shown other than as defined in the appended claims.
