10 Claims.

This invention relates to improvements in-bar mountings, and more particularly to a device for mounting a bar for use as a door pull, as a towel bar, or as a part of a household fixture.

The primary object is to provide a novel, simple and inexpensive device of this character which is easily installed and assembled, whose securing means are camouflaged or concealed, which supports a bar firmly and securely, and which may have any desired decorative appearance.

A'further object is to provide a device of this character adapted for use as a door pull in conjunction with a similar device located at the opposite side of a door, wherein the parts are secured together in clamping engagement with the door by a single securing member accessible at the interior of the door and concealed, so that the device cannot be tampered with, or part or all thereof removed or disassembled by an individual located at the exterior of the door.

A further object is to provide a device of this character, including a pair of cylindrical members adapted for end abutment with a supporting surface, said cylindrical members having a series of circumferential grooves and at least one member mounting a concentric end part whose junction therewith is not discernible by reason of the similarity of the appearance of the line of junction to the appearance of said grooves, said members having sockets to snugly receive and support opposite ends of a bar extending therebetween.

A further object is to provide a device of this character wherein a pair of rigid similar elongated hollow members are adapted for end abutment with a support and are provided with transverse bar-receiving apertures, said members extending through transverse apertures in the bar to hold the bar against longitudinal and rotative movement.

Other objects will be apparent from the following specification.

In the drawing:

Fig. 1 is a side view of one embodiment of the invention with parts thereof shown in axial section.

Fig. 2 is a fragmentary axial sectional view of a modified embodiment of the invention.

Fig. 3 is an axial sectional view of another embodiment of the invention.

Referring to the drawing which illustrates the invention as used for the purpose of mounting bars upon a door to serve as door pulls, and referring particularly to Fig. 1 thereof, the numeral l designates a door panel which is provided with a pair of spaced openings I2 extending therethrough. The invention is particularly panel I0.

adapted for use in conjunction with a solid glass door, and as here illustrated the door panel I0 is illustrated as being formed of glass. It will be understood, however, that the device'may be used in conjunction with a door formed of any material desired. It will be assumed in each instance that the surface of the door panel l0, positioned lowermost in the figures, is the outer door surface, and that the surface positioned uppermost in said figure is the inner surface of the door.

In the embodiment illustrated in Fig. 1; a pair of cylindrical members [4, preferably formed of metal such as aluminum, are mounted in -register with the openings I2 of the door at the outer surface thereof, the same preferably bearing against gaskets l6 interposed between the same and the surface of the door. The cylindrical members are preferably formed of solid bar material as shown, and at their inner ends each is preferably provided with a central longitudinal internally screw-threaded bore |8.- Adjacent .its outer end each member has a socket 20 member 32 extends therethrough and through the gasket 28 or the opening l2 of the door panel Ii), the gasket l6, and is threaded into the socket l8 of the member l4. Each screw is provided with an enlarged head 34 which seats against the base 30 and permits the parts to be drawn together for firm end abutment of the members l4 and 24 with the opposite surfaces of the door In the preferred embodiment of the invention, the openings [2 in the door panel are preferably of larger diameter than the diameter of the bolt 32, and an annular gasket member 35 having an outer dimension to fit snu ly in the opening 12, and an inner dimension to fit snugly around the bolt, is inserted in the door opening. The member 36 is preferably of slightly greater normal length than the thickness of the doorpanel l0; consequently as the members l4 and 24 are drawn together by the bolt 32, the member 35 is compressed longitudinally and expanded laterally to insure a snug fit of the parts and to prevent free play of the members I4 and 24 transverse of their axes.

Each of the members 24 has a transverse socket 38 formed therein adjacent its outer end,

and these sockets receive the outer end portions 7 24. In the embodiment of the invention shown,- the margin of the closure member 46 at its inner portion is beveled at 48, and the upper or outer margin of the member 24 is similarly beveled at 50. The two bevels 48 and 50 provide at the line of separation between the closure 45 and the members 24 a shallow V-shaped circumferential groove. At one or more longitudinal pointsalong each'ofthe members 24 are formed circumferential I grooves 52-, 7 preferably of the same size-and shape as the groove formed by the beveled faces48 and 50. Similar circumferential grooves 54-"may be formed in the members M if desired. By reason of the provision of the grooves 52 and the matching thereof with the grooves defined in the bevel edges 48 and 553, the lineof separation between the closures 35 and the "members 24 is camouflaged-or concealed so that when the closures 46 have been drawn tight toeliminate any free play or rotation thereof, the manner by which the memberszs and 14 are secured to the door is completely concealed. This insures against tampering, as by children, and prevents-any'posSible occurrence of partial or complete disassembly of the door pull. Inasmuch as the outer members l4 which mount the outer door pull part 22 are concealed, no possibility exists, without complete breakage of the members l4, of removing the same from the exterior of the door.

Fig. 2 illustrates another embodiment of the door pull' of different construction. In this instance the members 60 mounting both the inner bars 40 and the outer bars 22 are of similar construction and are preferably tubes whose inner ends'bearagainst the opposite surfaces of the doorpanel Ill in substantially axial alignment or bearagainst gasket members 62 interposed between; the same and said door. An annular resilient positioningmember (i5 is seated snugly in each opening [2, and an elongated rod 84 extends therethrough and projects at its opposite end substantially the full length of each of the members 60. Closure plates 66 are provided with reduced dimension inner portions 58 fitting snugly within the tubes 60 and are shouldered at-IO to bear against the outer ends of said tubes; The inner faces of the closures 66 are provided with central screw-threaded sockets l2, and the opposite end portions 74 of the bar 64 are screw-threaded for reception in said socket 12. The threading of the closure 68 onto the threaded end 14 of the bar 64 serves to draw the members 60 firmly against the opposite faces of the door panel l0 andto hold the device in ass mlq e ro ion.

The tubular members are provided with a transverse aperture 16 of a size to snugly receive the associated one of the bars 22 and 48. These bars are of a lengthto extend into and substantially across the interior of the members 60 and are provided at the portions thereof within said memberstfl with a transverse passage 18 having a frfeei sliding fitaround the bar. 64. It will be apparent that in this embodiment of the invention, the two bars and 22 are held firmlyagainst both endwise movement and rotative movement. The adjustment of the parts to effect their assembly is accomplished easily by applying the member 64 to the door and then applying the members 60 and their associated parts as a unit around the bar 64 into end abutment with the door panel, following which the closure 66 may be applied.

A third embodiment of the invention applicable for use as a door pull, wherein the bars 22 and 4,0 are mounted at the outer and inner sides, respectively, of a door panel It provided with apertures I2, is illustrated in Fig. 3. In this embodiment of the invention the bar mounting members are preferably similar, being of tubularconstruction and having inwardly projecting flanges 82 at their inner ends adapted for abutment with the opposite faces of the door panel [0 or with gaskets interposed between the same and said door panel. A resilient annular gasket member 84 is located within each door opening I2 as in theother embodiments, but preferably is of a length equal to the thickness of the door panel I0 plus the thickness of the two flanges 82. Circular plates 86 fit within the members $0 and bear against the outer surfaces of the flanges 82. A bolt 88 has an enlarged head 90 bearing against one of the plates and having screw-threaded engagement with the oppositeplate 86, the shank of said bolt passing snugly through the resilient member 84 and servingto longitudinally compress said member as the parts are drawn to fully secured and firmly anchored position.

Each of the members 80 has a transverse opening 92 adjacent its outer end to snugly receive the end of theadjacent one of the bars 22 and 40. Thebars 22 and 40 are each of a length to project into the memberstll in intersecting relation to the axis thereof and areprovided with internally screw-threaded transverse sockets or bores 94 substantially axially aligned with said members 80. Closure plates 9ii bear against the outerends of the tubes 80 and mount central inwardly projecting screw-threaded studs 98 which may be threaded into the sockets 94 to hold the closure plates upon the members 80. At the same time the threaded. engagement of the closure studs with the respective bars 22 and 46 hold said bars against endwise movement and against rotative movement.

In each of the embodiments shown in Figs. 2 and .3, the members wand $0, respectively, may be provided with one Or more circumferential groovesfii andfit, respectively, so shaped and positioned as-to .conceal the. line of separa tionoftne closures mounted upon the outer ends.

of said bars in the same manner more particularly described above with reference to the construction shown in Fig. 1.

While the invention has been illustrated herein as embodied in the door pull. unit, its use is not limited thereto, and the'construction may be utilized for other purposes, such as use as a towel bar or the like. part of-thedevice 'iilustra-tedabove the panel is in the drawing will-be employed; Thus it will be apparent that, the bolt 32 of the Fig. l embodiment may be replaced bye-wood screw or the like adapted'tobe anchoredin a wall, molding or other support, for the purposeof positioning the two members 'in operative relation to said supportfor the purpose'oi? mounting the bar 46.

to secure amemberxws to asupport; Theiadap- In such uses only that.

tation of the construction illustrated in Fig. 2 requires a slight change therein, specifically the fixed anchoring of a bar or stud 64 to the well" before the Fig. 2 construction can be assembled and mounted upon the wall.

While the preferred embodiments of the in- :members and extending through said openings for anchorage with the members of the other vention have been illustrated and described herein, it will be understood that changes may,
