1541 TWWA'Y TRAVEL FRONT PANEL [751 e slides to pery and rearwardly e` 20 Claims, 5 Drawing Figures Frimmel et al 19 INCHES Vouk Pmmfnm 4ms IIIIIIIIIIII IQINCHES I5 INCHES TWO-WAY TRAVEL FRONT PANEL It is a prim-ary` object of our present invention to provide a two-way front panel for use upon a chassis or drawer of the type which is conventionally supported by drawer slides in a cabinet frame, the 'front panelv being retractable from the conventional I9, 24, 30, etc. inch front panel width to a width equal to or less than l5, 20, 2-6 inches, respectively, which are the conventional drawer widths.
To our knowledge, a front panel in accordance with the disclosure herein has not heretofore been suggested.
lOur invention, therefore, is a cabinet structure comprising a cabinet frame having forward and rearward sides, a chassis drawer having opposite sides or side walls and forward and rearward ends, a slide extending along eachside of the drawer and supporting it in the frame for rectilinear movement forwardly and rearwardly. from its. normal position relative to the frame, and panel means mounted on one end of the drawer. Our preferred panel means includes a pair of side pan- 'els and means for mounting the side panels for lateral movement on the drawer between respective outer positions and inner positions. The side panels are engagey able with the frame in their outer positions to prevent movement of the drawer on the slides in at least one direction relative to the frame. The side panels are disposed laterally inwardly from the slides in their inner positions to .permit movement of the drawer forwardly and rearwardly on the slides.
Of course, the normal position for the drawerl is when its forward and rearward ends coincide, respectively, with the forward and rearward sides of the cabinet frame. ln some applications, it is very convenient to havethe drawer movable rearwardly out of the cabinet frame so that personnel may have access vto'whatever is in the drawer from the rear side of the cabinet frame.
This is particularly convenient for use in cabinets which contain electronic equipment of various types.
Our preferred panel means includes a base plate mounted on the -drawer and track means for mounting the side panels for rectilinear lateral movement on the base plate. The base plate andthe side panels are preferably generally flat, and the side panels preferably lie generally in a commonvertically extending plane parallel to the plane of the base plate and spaced forwardly thereof. The panel means also preferably includes av parallel and generally flat center plate mounted on the base plate and spaced forwardly of the side panels, the center plate having opposite outer side edge portions overlying the inner side edge portions of the side panels. A forwardly projecting handle or handle means is provided on the side panel for moving the panels outwardly and inwardly. Means mounting eachhandle means for movement between a releasing position and a locking position and locking means cooperating with the handle means to prevent lateral movement of each side panel when its handle means is in its locking position are provided. Our preferred handle means, mounting means and locking means will be discussed hereinafter.
We preferthat the side panels, in their outer positions, prevent movement ofthe drawer in either direction relative to the frame. We accomplish this by having the side panels themselves engage, respectively,'forward edges of the frame and then provide lock plates or conventional spring-loaded latch-type fasteners car- 2 ried by each side panel to engage rearward edges of the frame.
Thus, it is an object of our invention to provide a `front panel for a drawer-movable in a cabinet frame,
the front panel serving as a means .for locking the drawer in its normal position and being laterally collapsible to permit the drawer to move both forwardly and rearwardly relative to the cabinet.
Other objects and features of our present invention will become apparent as this description progresses.
To the accomplishment of the aibove and related objects, this invention may be embodied in the forms illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specitic constructions illustrated and described, so long as the scope of the appended claims is not violated.
In the drawings:
FIG. 1 is a fragmentary elevational view showing one embodiment of our two-way front panel on a chassis mounted in a cabinet frame; v
FIG. 2 is a fragmentary sectional view taken along the lines 2-2 in FIG. 1;
FIG. 3 is a fragmentary sectional view looking down at the top of our two-way front panel;
FIG. 4 is a fragmentary view showing another embodiment of our front panel collapsed so that the chas- .sis can move inwardly relative to the cabinet; and
FIG. 5 is an enlarged fragmentary sectional view of fthe spring-loaded Ilatch shown in the embodiment of tive to a cabinet frame 14 (only a portion of which is shown) by means of drawer slides indicated at 16. The
drawerslides 16 may be of the type disclosed in United States patent application Ser. No. 321,535 filed Jan. 5,
1973 which'include an inner track member 18 connected to the chassis l2, an outer track member 20 connected to the cabinet frame 14 and an intermediate track member 22. Such drawer slides are constructed so that the intermediate track member 22 will reciprocate relative to each inner and outer track member 18, 20. This means that the chassis 12 can move forwardly out of the cabinet frame 14 or rearwardly out of the cabinet frame unless there is an obstruction preventing such movement. The front panel means of our present invention, however, is not limited to any particular type of drawer slide.
Our two-way front panel l0 comprises 4a rectangularly shaped, generally flat, vertically extending back plate 30 which may be rigidly connected to the chassis l2. Upper and lower horizontally extending female track members or slide members 32, 34 are mounted upon the backplate 30for-a purpose which will be discussed hereinafter. An inverted, U-shaped stop block 36 is also rigidly mounted to the backplate 30 to provide, at laterally spaced apart positions, downwardly extending legs 3S, 40. At laterally spacedapart points, below the upper track member 32 and above the stop block 36 are guide blocks 44, 46, each of which may be, for instance, two inches in horizontal length. Finally, a center plate 50 which is parallel to and forwardly of the back plate 30 is centrally mounted upon the back plate by means such as the illustrated standoffs 52, 54.
We then provide side panels 60, 62 at opposite sides of the center plate and disposed between the center plate 50 and the back plate 30. These side panels 60, 62 are mounted for rectilinear horizontal movement relative to the back panel 30 by means of upper and lower male trackmembers 66, 68 which slidably engage, respectively, the female track members 32, 34 mounted upon the back plate. This sliding engagement is best seen in. FIG. 2`. Thus, the side panels 60, 62 are rectilinearly movable horizontally as indicated by the arrow 74 relative to the chassis 12 while the chassis 12 is rectilinearly movable as indicated by the arrow 76 relative to the cabinet frame 14. Each side panel 60, 62 has an outer position (FIG. l) and an inner position (FIG. 4) between which it is movable. The manner in which the side panels 60,62 are manually moved will now be discussed. Each panel 60, 62 carries a handle 80, 82 which is fastened thereto by means of vertically spaced' apart fastening elements 84, 86. Particularly, each fastening' element 84, 86 includes a shank portion 90, 92 extending through a vertically elongated slot 98, 100 in the panel 60, 62. This fastening arrangement permits the handles 80, 82 to be vertically movable upon the panels. Each shank portion 90, 92 extends rearwardly to cooperate with the guide block 44, 46 disposed therebehind. Particularly, when each panel is in its outer position as shown in FIG. 1, the shank portions 90, 92 are engaging the outer' ends of the guide blocks 44, 46. In order to get the panels 60,
62 moved inwardly, it is necessary to lift the handles of the guide blocks. That is, when the side panels 60, g
62 areretracted to the position shown in the embodiment of FIG. 4, the shank portions 90, 92 are in engagement with or spaced inwardly from the inner ends v of theguide blocks 44, 46. In FIG. 1, we show that the fully extended two-way front panel is 19 inches in width while the collapsed two-way panel 10 is l5 inches in width. Thus, we prefer to make the guide blocks 44, I
46 a length such that the panels 60, 62 will move laterally, for. instance, 2 inches.
The panels 60, 62 lie generally in the same plane such that their inner edges 110,112 would serve as a stop limiting the inward movement of the panels. As best seen in FIG.' l, these inner edges 110, 112 are provided with cutouts 114 to accommodate standoffs 52, 54 mounting the front plate 50. In order to limit the movement of the panels 60, 62- outwardly, we place stop blocks '120, 122 adjacent theinner edgesof the panels to project rearwardly to engage, respectively, the
their position shown in FIG. 4, the chassis 12 can move out the front of the cabinet frame or out the rear of the cabinet frame as desired. In the positions shown in FIG. 4, the outer edges ofthe side panels 60, 62 are disposed inwardly to positions such that they can move in the direction of the arrow 76 relative to Athe intermediate track members 22 of the slides 16. This is, of course,
necessary to accommodate movement of the chassis 12 rearwardly from the cabinet frame.
In the embodiment of FIG. 4, we place conventional and commercially available spring-loaded latch-type fasteners 128er, 13 0a on the outer rear surfaces of the side panels 60, 62 to engage theiinwardly facing flanges 14a as best seen in the fragmentary view of FIG. 5.
With such catches 128a, 1300, the drawer 12 can be i l embodiment of FIG. 4, the blocks 44a and 46a are downwardly and outwardly extending legs 3 8, 40 of the stop block 36. v.
We want the two-wayv front panel 10 to serve as a lock holding the chassis 12 stationary relative to the Cabinet frame 14. For this reason, in the embodiment of FIGS. 1, 2 and 3, we place lock plates 128, 130 on the outer rear surfaces of the slide panels 60, 62 to engage the inwardly extending flanges 14a ofthe frame as best seen in FIG. 3. Thus, when the side panels are in their position shown in FIGS. l and3, the chassis 12 is locked against'movement in the direction of the arrow elongated such that the handles 80, 82 cannot move downwardly firmly to lock the panels 60, 62 in their outer positions. Thus, in the embodiment of FIG. 4,
only the spring 132 holds the panels in their outer positions. It will be appreciated that the spring 132, the body portion of which is wrapped around the stud 52 and the leg portions of which engage the cutouts 114, is merely illustrative and many different types of spring means may be used to urge the panels 60, 62 outwardly.
The stop block 36 may be made of a material that deadens the noise or shock when the blocks 120. 122 move against the downwardly extending legs 38, 4I). Alternatively` the block 36 or the blocks 120, 122 may be used-as mounting surfaces for noise and shock absorbing devices or layers of material.
