ATTORNEYS DRAWER-PULL AND LATCH ASSEMBLY Filed Nov. 13, 1961 Oct. 22, 1963 JOHN J. ROBBINS BY United States Patent 3,107,958 DRAWER-PULL AND LATCH ASSEMBLY John J. Robbins, Philadelphia, Pa, assignor to Rois Manufacturing 60., Inc., Philadelphia, Pa, :1 corporation of New Jersey Filed Nov. 13, 1961, Ser. No. 151,727 12 Claims. (Cl. 312-320) The invention relates to an improved drawer-pull and latch assembly.

It is an object of the invention to provide a drawer-pull and latch assembly which combines simplicity and economy of construction, a neat and pleasing appearance, and ease of manual operation.

Further objects and advantages of the invention will become apparent from the following description, read in conjunction with the accompanying drawings, in which:

'FIGURE 1 is a perspective view of a cabinet structure embodying the invention;

FIGURE 2 is an elevation of the back of a front drawer panel;

FIGURE 3 is a vertical section taken as indicated by lines 33 in FIGURE 2;

FIGURE 4 is a vertical section taken as indicated by lines 44 in FIGURE 2;

FIGURE 5 is a vertical section taken as indicated by lines 55 in FIGURE 2; and

FIGURE 6 is a side view of a drawer and its associated track member, illustrating the coaction therebetween.

In FIGURE 1 there is illustrated in perspective a cabinet 2 having sides 4, drawers 6 and a top 8. Each drawer has a front panel 14, and for further details of the drawer structure reference will be made to FIGURES 2 to 5. (These figures show the front panel assembly as disassociated from the cabinet and from the rest of the drawer structure.)

The front panel 14 preferably is constructed of a fairly heavy sheet metal and has its margins turned horizontally as indicated at 16 and thence backwardly as indicated at 18. In the case of the side and lower drawer portions, the remaining edges are directed as indicated at 20 and 22 to provide extensions adapted for connection to the drawer sides and bottom.

At the back of the panel 14 there is secured thereto as by spot welding or the like, a channel 26 having its horizontally directed legs indicated at 28. 'For each drawerpull there is provided in the panel 14 and channel 26 a pair of aligned openings 30 (FIGURE 5), and in such openings there is received a drawer-pull body 32. Each body 32 is in the form of a generally U-shaped wall defining a central opening 34, and has an ornamental front trim portion 36 overlapping the front of panel '14 adjacent its associated openings 36. Integral with the body 32, and also extending through openings in panel 14 and channel 26, are lugs 38. Body 32 is held in position, with its trim portion 36 against the front of panel 14, by means of a U-shaped clip 46 straddling each lug 3'8 and a screw threaded through the clip into the ing 38. Thereby the legs of each clip 46 are pressed against the back of the drawer panel as represented by channel 26.

Reciprocable within each body 32 is a drawer-pull member 44, which has a handgrip provided by a downwardly turned front lip 46 adapted to be acted upon by the fingers of a person using the drawer. Means for guiding member 44 in its reciprocation relative to body 32 comprise a narrow key 48 at each side of the member and slidably received in a corresponding groove 5% in body 32 (FIGURE 3). Member 44 has an upwardly directed abutment-extension 52 across its entire width, and small pins 54 extending inwardly from the sides of body 32 limit movement of the drawer-pull member 44 inwardly (i.e., toward the right in FIGURES 3 and 5).

As evident in FIGURE 2 a shaft 56, referred to hereafter as the latch rod, is associated with each drawer-pull and is journalled for rotation about its main axis by means comprising a plate 58 spot welded to channel 26 and having a free end 60 bent to receive the latch rod. The aligned inner ends of latch rods 56 are mechanically in terconnected by a rod 62 welded, braised or otherwise connected thereto. Thus the spaced rods 56 and the intermediate rod 62 constitute in effect a single shaft, in that rotation of one latch rod 56 is transmitted to the other. Each latch rod has an offset crank arm 57 which is acted upon by a pair of lea-f springs 64, eachspring 64 being clamped between a screw 42 and its associated clip 40 (FIGURE 3). Thus each latch rod 56 is urged in a clockwise direction (in FIGURE 3) by springs '64-, but this rotation is limited by engagement of its crank arm 57 with abutment-extension 52. To move member 44 outwardly (i.e., to the left in FIGURES 3 to :5), its latch rod 56 must be rotated in opposition to the action of springs 64. The outer end of each latch rod "56 is turned at a right angle to form a latch arm 65. Ann 65 has a hook defined by an outer camming surface 66 and an inside angularly directed latching portion 68. The arm 65 extendsrearwardly through an opening 70 cut in the panel margin .18.

Referring to FIGURE '6, the front panel 14 is shown with the drawer side-s 71 connected thereto. Secured to each side 71 is a channel having its legs 72 protruding therefrom. Within the cabinet structure a track is provided by a channel 74 having its legs straddling the channel legs 72, the upper of which rests upon a roller 76 rotatably connected to channel 74. Thus the opening and closing movements of the drawer to the right and left, respectively in FIGURE 6, involve a guiding of the drawer within channel tracks 74. It will be understood that each track 74 is stationarily mounted within the cabinet housing, usually by means of a cabinet side 4 (FIGURE 1). An abutment 80 adapted for cooperation with the hook of a latch arm 65 is provided by cutting out the channel track 74 as indicated at 78, and bending the tab inwardly to define the abutment 80. Abutment 8% is so positioned that when the drawer moves inwardly the camming surface 66 rides upwardly along the abutment 80 until the inside of the hook drops over the abutment under the influence of springs 64.

It may be noted that normally, i.e., when both drawerpull members 44 are in their fully inner positions and crank arms 57 are urged by springs 64 into engagement with abutment-extensions 52, the hooks of latch arms 65 are below the upper edges of abutments 80.

Reviewing the operation of the aforedescribed assembly, when the drawer is closed the hook of each latch arm 65 engages its abutment 80 to prevent opening of the drawer, as shown in FIGURE 6. Only a very slight clockwise rotation of a latch arm 65 (as viewed in FIGURE 6), however, is necessary to lift it from engagement with the abutment 80 and thereby permit opening of the drawer. This releasing action may be efieoted by operation of either of the drawer-pull members 44 shown in FIGURE 2. That is, by placing the fingers behind the lip 46 of either of the drawer-pull members 44 and pulling outwardly thereon its associated latch rod 56 is rotated clockwise (again in 'FIGURE 6, but counterclockwise in FIGURES 3, 4 and 5) by a drawer-pull abutment 52.

Patented Oct. 22., 1363 This rotation of latch rod 56 may be very slight, but it is sufiicient to rock the latch arm book out of engagement with abutment 3d. Because the rocking of latch rod 56 in the direction to effect release of the drawer is in opposition to the influence of springs 64, as soon as both drawer-pull members 44 are released the latch arm 65 will be returned to its FIGURE 5 position, Wherefore when the drawer is again closed the camming surface 66 will engage the abutment and ride upwardly until it drops over its upper edge. It is significant to note that by virtue of the interconnecting rod -62 between the spaced latch rods 56, the manual operation of either drawer-pull member 44 will effect the releasing action of the latch arm 65 at both sides of the drawer.

Among the advantages of the aforedescribed structure is that, as previously mentioned, the drawer may be unlatched by a very small relative movement of one or both of the drawer-pull members 44. Latches at both sides of the drawer may be released by either one of the drawer-pulls. The drawer-pull structure is in effect finsh with the front of the drawer panel, in that it projects therefrom only to the extent of the trim portion 36. The assembly presents a very neat appearance.

Certain variations from the specifically disclosed structure will be evident to those skilled in the art. For example, although two drawer-pulls have been illustrated in the drawings, it is evident that only one drawer-pull may be provided in certain cases, for example on a drawer of short width. If it is desired that a drawer should be opened only by the action thereon with both hands, the intermediate rod 62 may be omitted, whereby the latch rod arms at opposite sides of the drawer must be operated independently by their associated drawer-pull members. Although a latch is illustrated at each side of the drawer, a latch at only one side may be satisfactory. In such case either one or two drawer-pulls may be provided to operate this single latch. 7

Various other departures from the specifically disclosed embodiment of the invention may be made without departing from the scope thereof as defined by the following claims.
