ABSTRACT OF THE DISCLOSURE A tilt-proof cabinet construction including a housing, and at least one pair of drawers, cord means interconnecting said drawers, and of predetermined length for preventing more than one of said pair of drawers from being withdrawn from said housing to maximum extension at any one instant.
This application is a continuation of my application Ser. No. 445,583, filed Apr. 5, 1965, now abandoned; under the same title.
This invention relates generally to the field of drawertype cabinets and more particularly to an improved construction incorporating means for preventing the tipping of the cabinet owing to the fact that more than one drawer is withdrawn from the main housing thereof to a degree wherein the center of gravity of the cabinet plus con tents lies outside of the interior of the cabinet housing.
This problem occurs most frequently in the case of file cabinets, which are filled almost to capacity with paper files and where it is desired to obtain the contents from more than one drawer. Where a lower drawer is opened and the contents of an upper drawer are also desired by those who fail to return the lower drawer to its initial condition, upon the outward movement of the upper drawer the center of gravity is shifted sufiiciently toward the user as to tip the entire cabinet about a forward edge thereof with consequent danger of spilling the contents and possibly injuring the person standing in front of the lower drawers.
By assuring that at least one-half of the drawers are in closed position at any one time, where all of the drawers contain approximately the same load the shifting of the center of gravity outwardly of the cabinet can be effectively prevented. In the present invention, it is proposed to solve the problem by coupling pairs of drawers in such manner that only one drawer in each pair can be with drawn to the full possible extension, and should a second drawer of a pair be also pulled open, force is transmitted to the first drawer to close the same simultaneously with the opening of the second drawer.
It is therefore among the principal objects of the present invention to provide an improved cabinet construction which is so constructed that the center of gravity always remains within the confines of the cabinet portion thereof.
Another object of the invention lies in the provision of an improved construction for achieving the above end which may be incorporated into existing constructions at minimal cost.
Yet another object of the invention lies in an improved cabinet construction incorporating means for accomplishing the above object in which the additional cost thereof is minimal, thereby permitting consequent wide sale, distribution and use.
Yet another object of the invention lies in the provi- "Ice sion of improved means for assuring that the center of gravity of a drawer-type cabinet will not be shifted outwardly therefrom which means is fully concealed from view at all times thereby not materially affecting the external appearance of the cabinet.
A feature of the invention lies in the fact that the in corporation of the above described means in no way affects the otherwise normal operation of the cabinet.
These objects and features, as well as other incidental ends and advantages, will more fully appear in the progress of the following disclosure and be pointed out in the appended claims.
In the drawing, to which reference will be made in the specification, similar reference characters have been em ployed to designate corresponding parts throughout the several views.
FIGURE 1 is a fragmentary view in perspective, partially broken away to show detail, of an embodiment of the invention.
FIGURE 2 is a similar view in perspective, showing the drawer portions thereof in partially extended condition.
FIGURE 3 is a similar view in perspective, showing one drawer in fully extended condition and the other in fully closed condition.
FIGURE 4 is a fragmentary view in perspective showing an alternate form of the embodiment.
FIGURE 5 is a longitudinal central sectional view, partly in elevation, of the alternate form.
In accordance with the invention, an embodiment thereof, generally indicated by reference character 9, includes a housing 10. The housing may be formed of wood, metal or other suitable material, and includes an upper wall 11, a rear wall 12, a pair of side walls 13, and a lower wall which may be positioned either directly upon a supporting horizontal surface (not shown) or be provided with a base structure 16 in turn resting upon a floor. A front wall 17 is provided with openings 18 and 19 to slidably receive a corresponding plurality of drawers 20 and 21 which are mounted on suitable suspension members 22 and 23 (see FIGURE 5).
The drawers 20-21 are substantially similar, and, as is well-known in the art, each includes a bottom wall 24 and side walls 25 and 26 having elongated grooves 27 therein for engaging the suspension members 22-23. The walls 2426 are interconnected inwardly thereof by a rear wall 28, and forwardly thereof by a front wall 29 having a suitable handle 30 and optional locking means (not shown).
Disposed upon an inner surface 31 of the rear wall 12 are first and second eyelet members 32 and 33, respectively. Where the construction is of wood or similar material, the members 32 and 33 are preferably in the form of conventional screw eyes of well-known type. Passing through the eyelets 32 and 33 is an elongated cable or cord 34 having first and second terminals 35 and 35a, respectively, secured to a portion of the side wall 25 of each of the drawers 20 and 21. As best seen in FIGURES 1, 2 and 3, depending upon the position of the drawers, the cable or cord 34 forms a continuously variable upper horizontal segment 36, a vertical segment 37 of constant length, and a variable horizontal segment 38.
Referring to FIGURE l, where both drawers 20 and 21 are in a closed position, either drawer may be pulled outwardly without interference. Should the lower drawer 21 be pulled part way out, the upper drawer 20 may also be pulled part way out without interference, in which case the center of gravity of the cabinet drawers and contents remains just inside the housing 10. Should the lower drawer 21 be pulled outwardly to fullest possible extension, the cord or cable 34 becomes tensed and motion is transmitted through the same to result in rearward or inward movements of the upper drawer. It will be observed that no more than two drawers need to be coupled to each other, since in the case where the cabinet has four or six drawers it is still only necessary to keep three drawers within the cabinet at all times in order to maintain the center of gravity also within the cabinet.
Turning now to the alternate construction illustrated in FIGURES 4 and 5, this construction ditfers from the principal form in that the cord is mounted so as to engage the rear wall of the drawers rather than a side wall thereof. This, the alternate form. generally indicated by reference character 40, includes a portion 41 of the inner surface of the rear wall of the housing where an eyelet 44 is mounted. and a corresponding rear wall of the drawer 43 which mounts an eyelet 45. This construction, while useful, has a disadvantage in that the full width of the cabinet cannot be as effectively utilized, as illustrated in FIGURE 5.
I wish it to be understood that I do not consider the invention limited to the precise details of structure shown and set forth in this specification, for obvious modifications will occur to those skilled in the art to which the invention pertains.
I claim:
