INVENTOR.

CARL H. LITTLE ATTORNEYS DOOR PULL SUMMARY OF THE INVENTION The present invention primarily relates to pulls for sliding doors or the like.

Specifically, the pull is of two part construction including a pull piece shaped to be received within a generally rectangular door mounting opening and to engage a front surface of the door about such opening, and a resiliently deformable rear piece, which engages a rear surface of the door and cooperates with the pull piece to retain the pull in assembled condition.

The pull piece is preferably of integrally formed molded plastic construction including a rear portion having bottom, top and side or pull wall portions, which are end edge jointed to define an open ended box received within the door opening, and a cover or face plate portion, which is joined to the front edges of the wall portions and defines a lip portion adapted to lie in abutting engagement with a front surface of the door. The cover portion is also formed with a centrally arranged pull or finger access opening to be used in both assembly of the pull and subsequent operation of the door. The top and bottom wall portions are formed with rearwardly extending, facing generally L-shaped retaining fingers or members, which are preferably formed with forwardly facing cylindrically convex cam surfaces.

The back piece is in the form of a generally rectangular, resiliently deformable plastic plate provided with a pair of parallel ears or rib projections arranged in an inwardly spaced relationship relative to vertically disposed opposite edge portions thereof.

The pull is assembled with the pull piece locked within the mounting opening by slide fitting the back piece between the rear surface of the door and cam surfaces of the retaining fingers, while bowing the back piece rearwardly by finger pressure applied through the pull access opening until each of the back piece ears snaps into seated engagement within the side wall portions and both vertical edge portions lie in abutting engagement withthe rear surface of the door. Resilient deformation of the back piece additionally accommodates for variations in door thickness.

While the pull of the present invention is primarily intended for use with sliding doors, it may be used in the operation of other types of closures, as for instance a pull for drawers.

DRAWINGS The nature and mode of the present invention will now be more fully described in the following detailed description taken with the accompanying drawings wherein:

FIG. 1 is a front. perspective view showing the door pull of the present invention installed within a door opening;

FIG. 2 is an exploded rear perspective view of the door pull illustrating the preferred installation technique; and

FIG. 3 is a sectional view taken generally along line 3-3 in FIG. 2, but showing the pull fully installed.

DETAILED DESCRIPTION To facilitate understanding of the present invention, the present pull, which is generally designated as in the drawings, will be described as being used in association with a horizontally sliding door or closure 12 having a generally rectangular pull mounting opening 14 extending between front and rear door surfaces 16 and 18, respectively. However, as will be apparent. pull 10 is not limited solely to use with this type of closure, and may for example, even be employed as a drawer pull.

Pull 10 is shown in FIGS. 1 through 3 as including a pull piece 20, which is formed with a rear portion 22 and a front cover or plate portion 24, and a back piece 26. Rear portion 22 is best shown in FIG. 2 as being essentially in the form of an open ended box, which is of generally rectangular cross section and dimensioned to be freely accommodated within door mounting opening 14."Specifically, rear portion 22 is formed from end edge joined wall portions including like top and bottom wall portions 30 and 32 and like pull or vertical side wall portions 34 and 36; such wall portions in turn being front edge joined to the rear surface of front cover 24. Preferably, pull piece 20 is of integrally formed molded plastic construction.

As will be apparent from viewing FIGS. 2 and 3, pull wall portions 34 and 36 have a width-wise dimension, which preferably corresponds substantially to the minimum thickness dimension of a door with which the pull is to be employed, and top and bottom wall portions 30 and 32 are formed with a pair of rearwardly extending, facing, generally L-shaped retainer fingers or members 38 and 40, respectively. Retainer fingers 38 and 40 include facing guide portions 42 and 44, which are arranged in a vertically offset or stepped relationship relative to adjacent inner facing surfaces of top and bottom wall portions 30 and 32, respectively; and retaining portions 46 and 48, which upstand from guide portions 42 and 44 and are formed with forwardly facing vertically aligned, cylindrically convex cam surfaces 50 and 52. Guide portions 42 and 44 are preferably formed to extend completely across the rear of rear portion 22. Front cover 24 is shown as being dimensioned to extend transversely beyond rear portion 22 so as to define a marginal lip or overhang portion 54 adapted to lie in abutting engagement with door front surface 16 about opening 14. To permit assembly and subsequent operation of pull 10, front cover 24 is formed with a user finger access opening 56, which preferably extends vertically between the inner surfaces of wall portions 30 and 32, but is inwardly spaced relative to the inner surfaces of wall portions 34 and 36.

Back piece 26, which is best shown in FIGS. 2 and 3, is preferably in the form of a generally rectangular, resiliently deformable plastic plate having a pair of integrally formed ear like members 58 and 60. Members 58 and 60 are arranged to project forwardly of and be inset relative to spaced edge portions 62 and 64 of the front surface of the back piece. By again referring to FIS. 2 and 3, it will be understood that the back piece 26 is dimensioned to permit edge portions 62 and 64 to engage door rear surface 18 adajcent opposite sides of opening 14; to permit oppositely facing surfaces of ear members 58 and 60 to be arranged closely adjacent facing surfaces of wall portions 34 and 36, respectively; and to permit upper and lower marginal edges 66 and 68 to lie closely adjacent guide portions 42 and 44, respectively, when pull 10 is in assembled condition. Preferably, ear members 58 and 60 are of a length permitting their upper and lower ends to lie immediately adjacent the facing surfaces of wall portions 30 and 32, as indicated in FIG. 1.

It will be understood that pull may be assembled by first inserting rear portion 22 within mounting opening 14 and thereafter slide fitting back piece 26 in the direction indicated by arrow 70 in FIG. 2, between door rear surface 18 and cam surfaces 50 and 52 with marginal edges 66 and 68 in sliding engagement with guide portions 42 and 44 until both of the ear members snap into engagement with the side wall portion and both edge portions lie in abutting engagement with the rear surface of the door. Sliding and rearwardly bowing of the back piece to the degree required may be assisted by finger pressure applied through access opening 56. As will be apparent from viewing FIG. 3, the resilient nature of the back piece permits the latter to be deformed to the extent indicated at 26' in order to accommodate for doors having thickness varying upwardly at that indicated at 18. After assembly of pull 10, door 12 may be slid in opposite directions, as indicated by arrow 72 in FIG. 1, by a user inserting one or more of his fingers through opening 56 and applying finger tip pressure upon either of side wall portions 34 or 36; such wall portions in turn transmitting operating pressure to door 12. Unintentional slippage of the tips of the users fingers from engagement with such wall portions is effectively prevented by the rearwardly facing surfaces of cover plate 24 adjacent opening 56.

While the back plate has been described as being resiliently deformable, it will be appreciated that it should be as stiff as is commensurate with pull assembly requirements in order to retain lip 54 firmly seated adjacent door front surface 16.
