Oct. 7, 1958 H. A. SPERLICH 5 CABINET STABILIZER Filed March 19, 1954 United States Patent CABINET STABILIZER Herman A. Sperlich, Highland Park, Mich., assignor to Ironrite, Inc., Mount Clemens, Mich., a corporation of Michigan Application March 19, 1954, Serial No. 417,404

8 Claims. (Cl. 45-137) The present invention relates generally to the stabilization of free-standing cabinet-style furniture. The invention has specific reference to the stabilization of cabinet-style ironers of the type wherein the top is hinged so as to be laid back for access to the rolls.

It is a problem to design home-type furniture and cabinet-style appliances so as to be possessed of satisfactory stability, yet which fit into the decor of the smaller rooms of modern homes and are otherwise artistically and aesthetically proportioned according to the dictates of style and design. Also, ironers, sewing machines, dish washing machines, and the like need be enclosed in cabinets because these machines now are used in multipurpose rooms such as kitchens, recreation rooms, utility rooms and the like, and it is necessary to fit the cabinet into spaces between already existing counters and other items of built-in furniture. The size and proportions of the cabinet thus are arbitrarily set irrespective of the inherent stability needs of the piece. Because of the complete enclosure, cabinets must be hinged, folded, or the entire interior mechanism arranged to slide or swing out to permit access to the working parts of the appliance. With roll type ironers this has necessitated a cabinet having a heavy, hinged top portion which is swung or laid back before use.

It is a principal object of this invention, therefore, to provide a simple concealed stabilizer for free-standing furniture cabinets having outwardly-extending tops, cabinet sections, or outwardly slidable mechanisms. A more specific object is to provide a hinged-top ironer cabinet which is sufiiciently stable for modern use yet which is of satisfactory portability to be usable any place in the home.

Still other objects and advantages will be apparent to those skilled in the art upon referring to the following description and the accompanying drawing, in which:

Figure 1 is a perspective view of a cabinet-style ironer, with portions of one leg broken away to show the location and details of mounting of the stabilizer of this invention;

Figure 2 is an end elevation of the lower portion of the ironer leg, the figure being viewed in the direction of the arrow 2 shown in Fig. 1;

Figure 3 is a side elevation in section of the lower portion of the ironer leg of Fig. 1, the figure being viewed in the direction of the arrows 33 in Fig. 2; and

Figure 4 is afront view of the supporting bracket shown in Figs. 2 and 3, the figure being viewed as a section taken in the direction of the arrows 4-4 shown in Fig. 3.

The cabinet to which the stabilizer of this invention is appliedis shown in Fig. 1 to be a cabinet-style ironer, which ironer comprises two bench-style or box-style hollow legs 1, 2 supporting a platform or work table 3 on which is mounted a roll-type ironer mechanism, indicated generally by the numeral 4. In this machine the work table extensions 5, 6, and 7 fold up to permit the hinged top 8 to be lowered over the entire assembly. The hinged top 8 is necessarily deep and, since it usually is fabricated of porcelain or enamel-coated sheet steel, is of appreciable weight. In designing this machine, the depth of the legs 1, 2 was restricted in order to make the cabinet fit snugly against the wall without extending beyond the depth of standard cabinets and the like. The height of the machine was designed to permit the use of the top surface of the closed cabinet as a work table or extension of an ordinary kitchen cabinet. Thus, the cabinet is somewhat too shallow for its height when the cabinet is open. This machine is mounted on four small casters 9, 9 attached to a channel-like bottom member 10 (as shown in Figs. 2 and 3) so as to enable the operator easily to roll the machine forward away from the wall to obtain room to swing back the cabinet top 8 and expose the ironer mechanism 4. Without the stabilizer of this invention, the heavy cabinet top 8 tends to raise the front casters off the floor and make the machine somewhat unstable.

However, when provided with. the spring-loaded, selfextending automatic stabilizer, shown generally in Fig. 1, and more specifically in Figs. 2 and 3, the weight of the folded-back top 8 is e'fiectively supported and tipping is prevented. As shown in Figs. 1 and 2, the stabilizer comprises an arm 20, in this illustration L-shaped (see Fig. 3), located in the lower corner of the back wall 21 of each of the legs 1, 2 with the front portion of the long end or shank 22 passing through a supporting hole in the wall 21 and the short end or bumper-rest pgption (see Fig. 2) 23 pointing downwardly. On the lower end of the bumper-rest non-marring, non-skid tip 24 of rubber or other cushioning material. The length of the bumper-rest portion 23 is such that it normally does not contact the floor when the cabinet top 8 is in the closed position. In order to do this the tip 24 in the ironer illustrated is about 0.25" oil the floor when the cabinet is closed. The length of the shank 22 likewise is dependent on the weight and dimensions of the cabinet. Both of these dimensions, it will be appreciated, may be varied considerably to suit the circumstances of use so that in any case, when the cabinet is in the open position, an almost imperceptible backward tipping of the machine (without the front casters necessarily leaving the floor) will bring the bumper-rest portion 23 of the arm 20 into contact with the floor and enable it to take up unsupported weight.

Referring now to Figs. 2 and 3, the arm 20 is located with its shank 22 slidably mounted through a hole in the wall 21 and its inward or rearward end '25 slidably supported in an angle bracket 26 attached to the bottom leg channel 10 inside the hollow leg 1. A compression spring 23 is spirally wound around the shank 22 so as to bear on one end against a pin 28 projecting on both sides of the shank. The pin 28 is located to form a stop at an intermediate point in the shank 22 determined by the length of outward extension desired in the arm 20. The other end of the spring 27 bears against the flat surface of the angle bracket 26.

As shown most clearly in Figs. 3 and 4, the upper surface 29 of the inner end 25 of the shank 22 is ground flat for a portion of its length with a curved or feathered taper at 30, the exact location of the taper being selected depending on the distance of inward travel desired in the arm 20. As shown most clearly in Fig. 4, thei'angle bracket 26 has a hole 31 of a similar segmental circular shape and which is proportioned to enable it to cooperate with the curved taper portion 30 of the shank 22 to act as a frictional stop limiting inward travel of the arm 20. Thus the arm 20 is normally extended, with the pin 28 contacting .the leg wall 21, when it is free 'to respond to the urging of the compression spring 27. It will also be seen that this arm 20 is free to slide into the leg 1 when the cabinet is pushed intoan obstacle such 23 there is provided a non-staining or as a wall or other piece of furniture, damage to the leg wall 21 by contact thereof with the bumper-rest 23 being prevented by the taper ground friction stop 30. The length of the downwardly extending bumper-rest portion 23 and the overall length of the shank 22 is easily determined for any cabinet, as is the location of the stabilizer itself and its pin and friction stops, by a simple calculation of opposed forces operating through the distance of the extended portion of the arm 20.

In use, the ironer illustrated is first pulled forward, away from the wall or other piece of furniture, in order to make room behind it to fold back the cabinet top 8. When this is done the arm 2t automatically extends itself. After the top 8 is folded back the rubber tip 24 touches the floor and the machine is prevented from rocking or tipping over. After use, the operator folds the top 8 down again and pushes the machine back in its former place, the arm 20 being pushed into the cabinet leg by contact with any obstacle such as the wall or any other piece of furniture. The stabilizer thus is concealed in normal use and does not interfere with the portability of the machine nor does it prevent the operator from storing the machine against a wall or back-to-back against another piece of furniture.

It is obvious that more than one leg of the ironer illustrated could be provided with one of these stabilizing arms and that any other type of completely-enclosed style of cabinet-type of ironer could be provided with one or more of these stabilizers located anywhere in the lower edge of its back wall. It is also to be understood that cabinets of still other types could be provided with these stabilizers.

While it will be apparent that the preferred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation, and change without departing from the proper scope or fair meaning of the subjoined claims.

What is claimed is:
