Application March 1, 1952, Serial No. 274,433

2 Claims. (Cl. 292-347) This invention relates to latch assemblies for doors and more particularly to a novel means for firmly securing the rose of a knob assembly wherein it is possible to entirely conceal all attaching means and at the same time adapt the rose plate to telescopically enter the knob.

Door latch assemblies, particularly those used in ofiice buildings and dwellings must be highly ornamental in-appearance. This demand for an ornamental appearance requires a product having as neat and uninterrupted a surface appearance and design as possible. In the design of articles to obtain this desired goal, emphasis is placed upon the concealment of all functional elements particularly where they are not subject to ornamental design or camouflage.

In the elimination of all outwardly appearing anchoring means such as screws, two important factors must always be considered. The first of these factors is cost. Whatever device is utilized to replace these anchoring means must be simple to manufacture and economical both in materials used and manpower required to assemble the necessary parts. This requirement in itself is suificient to prevent the use of many structural arrangements normally employed for concealment where cost is not such an important factor. The second important factor is simplicity of assembly at the time the latch structure is mounted to the door. The latch assembly must be so designed that even an unskilled workman can readily and rapidly assemble and mount the structure without becoming confused and without the necessity of special tools. It has been found that complicated assemblies are frequently injured or returned as inoperative by the men installing them, merely because carefully worded assembly and mounting instructions were not heeded.

Wholly aside from the ornamental features of my invention, is the desirability of providing a watertight handle assembly. When the handle is used on the exterior of a structure, it is subject to rain, fog and snow. Since the internal operating mechanism of the handle, normally, is of steel the entrance of moisture is highly detrimental. By making the rose plate and the cover for the knob shank an integral part and extending the knob shank cover into the knob, all vertical joints in the external structure are eliminated. The joint between the shank cover and the knob is horizontal. Therefore, it does not readily admit water to the interior of the lock structure.

It is a primary object of my invention to provide a latch structure in which all mounting means for the rose plate are entirely concealed by a structure which is both simple to install and economical to manufacture. It is a further object of my invention to provide a structure which may be simply removed after initial installation should repairs or other circumstances require such removal. My invention contemplates an assembly permitting the quick spacing of the rose plate from the door face for painting of the door. Other objects include improved climatic resistance and integration of parts to reduce manufacturing costs.

Other objects and purposes of my invention will be "ice readily seen by those acquainted with the design and manufacture of hardware for doors upon reading the following specification and the accompanying drawings.

In executing the objects and purposes of my invention, I have provided a handle assembly including a base plate securely mounted to the face of a door. The base plate includes an outwardly projecting, tubular shank designed to rotatably and slidably receive the tubular sleeve of a knob. The knob and its sleeve are securely but detachably anchored to the stationary base plate by means which, when the rose has been finally mounted, are entirely concealed. The means for assembling the knob to the base plate is concealed by a rose. This rose slidably seats about the shank of the base plate and may be moved axially of this shank into the knob to reveal the knob anchoring means whereby the knob may be removed. The rose itself is securely held in position by concealed fasteners such as a resilient clip.

In the following description the terms inwardly and outwardly are frequently used and are to be taken to mean inwardly toward the center of a door and outwardly away therefrom. In the following description the terms inwardly and outwardly are used as if the handle assembly described were mounted on the outer face of a door.

Referring now to the drawings in greater detail, the numeral 1 indicates a generally circular base plate having an outwardly extending peripheral flange 2 (Figures 1 through 4). The flange 2 is turned back upon itself, forming a groove -3 opening radially inwardly toward the center of the base plate 1. The base plate 1 has a central aperture 4 (Figure 2) about which extends an inwardly ofiset depression 5. The holes 6 in the base plate 1 permits the base plate to be secured to the face of a door 8 by suitable fastening means such as screws 7.

Mounted to the base plate 1 is an outwardly extending, tubular shank 10. The shank 10 has, at its inward end, a radially extending lip 11 seated on and secured to the base plate 1 (Figure 7). Immediately outwardly of the lip 11 is the radial collar 12 of greater diameter than the main portion of the shank 10. Where the main portion of the shank joins the collar 12, the inner shank has a shoulder 13.

The grip portion of the handle assembly is a hollow knob 15 provided with an aperture 20 on its inward side. The hollow knob 15 is reinforced by an internal reinforcement 19. The aperture 20 is closed by means of an annular cover 21 having a peripheral rim 22, designed to engage the edge of the aperture 20 and detachably secure the a a; cover 21 to the hollow knob 15. The cover 21 has a central opening 23 of greater diameter than that of the shank 10. About the central opening 23, the cover 21 is flanged at 16, the flange 16 extending into the interior of the knob. Rotatably seated within the shank 10 is the tubular knob sleeve 14. The knob sleeve, at its outward end, is concentrically secured to the inner surface of the hollow knob 15. The knob sleeve 14 extends through the opening 23 in the cover 21 and is secured to the inner surface of the outward wall of the knob.

The base plate 1 is surrounded and covered by a rose plate 24. The rose plate 24 consists of a large, circular cover portion 25' at its inward end and a tubular, outward extension or shank 26 of such diameter that it will slidably receive the shank 10 and pass through the opening 23in the cover 21. The rose plate 24 is essentially an ornamental cover for concealing the internal, functional structure of thehandle assembly, the cover or flared portion 25 covering the structure adjacent the door and the shank or tubular portion 26 covering the outwardly extending knob mounting structure. The rose plate 24 also. serves as a weather resistant housing for the internal mechanism.

Seated within a major portion of the groove 3 at the periphery of the base plate 1 is a wire element 30. The wire element 30 has a portion extending across the base plate 1 to one side of the. center thereof (Figures 2, 3 and 4). Adjacent each end of this portion, the wire element 30 is secured to the base plate by a clip 32. Although they may be made as separate parts, preferably, the clips are punched out of the base plate as fingers having one free end and bent outwardly to seat over and clamp the wire element between them and the outward face of the base plate. Between the clips 32, the wire element 30 is formed into an outwardly extending loop 33. Mounted on the inner surface of the cover portion of the rose plate 24 is an inwardly projecting, resilient, striker element 34. The striker element 34 is designed to engage the loop 33. The striker element 34 and the loop 33 constitute the two operating parts of a friction latch.

Mounted in the radial collar 12 and seated in the depression of the base plate 1 is a cup 40. The cup 40 is of such diameter that it may receive the knob sleeve 14 therein. through its inward face, through which pass the projections 42 on the inward end of the knob sleeve 14 (Figure 8). The'cup 40 has an inwardly projecting, non-circular stem 43 for engaging and operating the roll-back of a latch assembly. When the handle assembly is designed for use with a key-in-knob type structure, such as that disclosed in'co-pending application, Serial No. 47,438, entitled Keyin-Knob Lock, filed September 2, 1948, now Patent No. 2,642,735, dated June 23, 1953, inventor Herbert Quigley, the stem is hollow. When the handle assembly is designed for use with other types of locks the stem 43 may very well be solid.

Seated within the inward end of the knob sleeve 14 is the locking ring 44 having a projection 45 on one side. T he'locking ring 44 is urged in the direction of the projcction 45 by the spring 46. The projection 45, under the urging of the spring 46, passes through an opening 47 in the side of the knob sleeve 14 into the opening 48 in the side wall of the cup 40. A pair of diametrically arranged access openings 49 are provided in the inner shank whereby access may be had to the projection 45. The access openings 49 are appreciably larger than the openings 47 and 48 to facilitate the entrance of a standard tool such as a screw driver.

The cup 40 as well as the knob sleeve 14 is freely rotatable with respect to the base plate 1 and inner shank 10. The spring 46 is held against movement axially of the knob sleeve 14 by the channel 50 in the inner surface of the knob sleeve in which one portion of the spring is seated. The cup 40, locking ring 44, spring 46 and the various apertures cooperating with these parts constitute the knob anchoring assembly and are not'part of the The cup 40 is provided with arcuate slots 41- invention forming the subject matter of this application but are briefly described herein for the purpose of making a complete disclosure of the operation and purpose of my invention. The knob anchoring assembly is fully disclosed and claimed in my co-pending application Serial Number 274,432, filed on March 1, 1952, and entitled Concealed Knob Anchor.

The rose plate 24 is, at a point radially aligned with the striker element 34, provided with a notch 54 in its outer edge (Figures 1 and 6). The notch 54 is of such length and width as to permit the insertion therethrough of the tip of a conventional, medium sized screw driver.

Operation In the assembly of my invention upon a door, the base plate 1 with the shank 16 secured thereto, is mounted on the face of a door by means of screws 7. Preferably, the base plate 1 is so oriented that the loop 33in the wire element 39 is at the lower end of the base plate. By this arrangement the notch 54 in the rose plate 24 is located at the bottom of the handle assembly Where it is substantially concealed. The rose plate 24 is then seated over the shank 10 with the resilient striker element 34 aligned with the loop 33. When the striker element 34 contacts the loop 33, inward movement of the rose will cease. At this point, additional pressure is put upon the rose to cause the striker element 34 to bend radially outwardly so that it may pass the loop 33. This permits the rose to move inwardly against the face of the door. The striker element will then snap radially inwardly on the inward side of the loop 33, securely holding the rose plate 24 against outward movement away from the door. The outwardly extending collar portion of the rose plate seats around the shank 10, preventing the rose plate from moving sideways to a position eccentric of the shank 16. Thus, the rose plate is held se-' curely in position. It will be recognized that the loop 33 can be made resilient and the striker element 34 rigid whereby the loop rather than the striker element flexes.

After the rose plate has been put in position, the knob assembly, with the projection 45 depressed, so that it will not interfere with the entrance of the knob sleeve 14 into the shank 10, is assembled to the shank 10. When the knob sleeve 14 has been passed all the way down the shank 10, the projection 45 will, in an inward and outward direction, be aligned with the opening 48 in the side Wall of the cup 40. Upon rotation of the knob until the projection 45 is circumferentially aligned with the opening 48, the spring 46 will force the projection out through the opening 48. The resistance of the roll-backs will hold the cup from rotating during this aligning process. Thereafter, the knob sleeve 14 and the cup 41 are securely held together by the projection 45. The knob assembly is held against outward movement by the shoulder 13 which prevents outward movement of the cup 40.

When the knob assembly is to be removed, a screw driver or similar tool is first placed in the notch 54 in the rose plate 24. The screw driver is rotated to pry the rose plate outwardly, disengaging the striker element 34 from the loop 33. The rose plate 24 may then be pushed outwardly with the collar portion of the rose plate passing through the opening in the cover 21 into the interior of the knob (Figure 10). This permits the rose plate to be moved outwardly sufliciently that the knob assembly may be released by passing the end of a'screw driver or similar tool through one of the access openings 49 in the shank .16 to force the projection inwardly to disengage the cup 40. Once the projection 45 and the cup 40 have been disengaged, the whole knob assembly may be withdrawn and thereafter the rose plate 24 may be withdrawn merely by pulling it outwardly over the end of the shank 10.

It will be recognized that the telescoping of the rose shank into the knob has, within itself, numerous functional and structural advantages which are independent of the concealed anchoring arrangement. Thus, this design for the rose plate may be used with exposed attachment means (Figure 11). In the structure shown in Figure 11, the rose plate 24a is secured to the base plate by screws 30 engaging suitable bosses 81 on the base plate 10. Upon removal of the screws 80 the rose plate 24a may be telescoped outwardly into the knob 15.

It is seen that my invention provides a simple yet positive means for concealing the entire functional structure at the base of the handle assembly as well as the anchoring means for the rose plate. At the same time, the en tire shank portion of the handle assembly from the door face of the knob is covered by a single, imperforate cover, protecting the internal mechanism against moisture or other physical injury. The telescoping of the rose into the knob permits the rose to be suificiently spaced from the door face, Without removal of the knob, to allow the door to be painted without injury to the hardwares finish. It will be recognized that although I have described one particular structure whereby the knob assembly may be detachably secured to a door in a manner entirely concealable by the rose plate, numerous other types of structures may be utilized for eifecting the anchoring of the knob assembly without in any way affecting my invention.

It will be recognized that various modifications of my invention may be made each without departing from the principle of my invention. Each of these modifications is to be considered as included in the hereinafter appended claims unless the language of these claims expressly provides otherwise.
