Description




FIELD OF THE INVENTION




The present invention relates to an improved adjustable picture hanging hook and, more particularly, to a picture hanging hook capable of allowing the vertical and/or horizontal position of an item to be hung thereon to be adjusted without having to re-mount the picture hanging hook.




BACKGROUND OF THE INVENTION




A variety of picture hangers have been previously designed and sold for the purpose of hanging picture frames and other items on walls and other vertical surfaces. Standard picture hangers typically are formed pieces of metal mounted to a wall by one or more nails and that include some sort of hook on which a picture frame is supported. Typically, wire extending across the rear side of a picture frame is supported by the picture hanger's hook.




One common problem associated with such standard picture hangers is the difficult task of positioning the picture hanger on the wall at an appropriate location such that the picture to be mounted thereon is located at the exact, desired location. A picture hanger is mounted to a wall usually by a nail. Mounting a picture hanger too high or too low, or too far to the right, or too far to the left, of the desired location, even by a fraction of an inch, in turn leads to the undesirable task of remounting the picture hanger itself, this time at a different location on the wall. Such remounting is wasteful, time consuming and results in the creation of unnecessary holes in the wall. These additional, unnecessary holes are aesthetically undesirable, may result in reduced wall strength, and ultimately need to be repaired. Still further, an already mounted picture frame may later need to be remounted as a result of shifting of walls which often occurs after a newly constructed structure has settled.




In addition to standard picture hangers, a variety of hangers have been designed that attempt to overcome the above-mentioned problem of standard hangers. For example, U.S. Pat. Nos. 3,330,525, 4,611,780, and 5,605,313 disclose just a few examples of hangers designed to provide multiple positions on which a picture frame may be mounted. However, while such prior art designs attempt to simplify mounting, none provide the user with both ease of use and a range of mounting positions to enable for quick and efficient mounting of a picture frame or other item to be hung.




OBJECTS OF THE INVENTION




Therefore, it is an object of the present invention to provide a picture hanging hook (sometimes called picture hanger or, simply, hanger herein) that is easy to use and manufacture and, at the same time, overcomes the above-mentioned problem associated with standard picture books.




It is a further object of the present invention to provide a picture hanging hook that enables for the easy modification of the picture hanging position in the vertical and/or horizontal directions.




It is another object of the present invention to provide a picture hanging hook that, once mounted to the wall, alleviates both the need to re-mount the picture hanging hook and alleviates any need to lengthen or shorten the wire which is attached to the frame.




Various other objects, advantages and features of the present invention will become readily apparent to those of ordinary skill in the art, and the novel features will be particularly pointed out in the appended claims.




SUMMARY OF THE INVENTION




In accordance with the present invention, an assembly for hanging picture frames and other objects to a vertical support includes a base adapted to be mounted to the vertical support, a wheel supported by the base and rotatable relative to the base, and a hook rotatably coupled to the wheel. The hook is adapted to rotate upon rotation of the wheel relative to the base, and the hook includes a hooked portion that can receive the item to be mounted thereon.




As an aspect of the invention, the hooked portion remains properly oriented to receive the item to be mounted thereon independent of the position of the wheel relative to the base.




As another aspect of the invention, the hook is disposed off-center to the front surface of the wheel.




As a further aspect of the invention, the base includes a bottom surface on which is provided a plurality of locking grooves. The wheel is disposed on a front surface of the base and includes a set of teeth disposed around the wheel's perimeter, and one of the teeth disposed on the bottom of the wheel is received by one of the locking grooves in the base.




As yet another aspect, the wheel can be raised so that none of the wheel's teeth are disposed in any of the base's locking grooves, and the wheel is longitudinally movable relative to the base when the wheel is in the raised position and the wheel can not longitudinally move relative to the base when lowered.




As a feature, the base includes an aperture that extends along the base and a stem extends from the center of the rear surface of the wheel. A holding disk is fixed to the stem, the stem extends through the aperture in the base and the holding disk is disposed behind the base. The holding disk has a diameter greater than a largest height of the aperture in the base so that the holding disk prevents the wheel from being fully separated from the base.




As another feature, the locking grooves include alternating teeth and recesses disposed along the entire bottom surface of the base, and the recesses receive the teeth disposed around the wheel.

DETAILED DESCRIPTION OF THE INVENTION




Referring to the drawings,

FIGS. 1 and 2

thereof are front view illustrations of the adjustable picture hanging hook of the present invention. As shown, the adjustable picture hanging hook


10


(or simply, hanger


10


) includes two main components: a support base


12


and a movable wheel


30


. Support base


12


(or simply, base


12


) and wheel


30


are movable relative to each other, as described further below. Base


12


includes a number of structural features including a set of rectangular teeth-shaped locking grooves


14


disposed on the bottom of base


12


. Locking grooves


14


includes alternating teeth


14




a


and recesses


14




b


and, as will be discussed, operate to prevent the rotation of wheel


30


once locked in place. Base


12


further includes a rim


16


extending along the base's top portion and which is disposed apart from the base's central portion


20


to provide a longitudinal gap


18


that extends along the base's top and in which a portion of wheel


30


is disposed, as will be further described. As is appreciated, rim


16


assists in retaining wheel


30


to base


12


, and provides additional strength to the device so that it can suitably support heavy items to be mounted. However, since holding disk


36


also retains wheel


30


to base


12


(to be discussed below), rim


16


can be removed.




Base


12


further includes a central aperture


22


disposed in its central portion


20


. Central aperture


22


extends along base


12


's width and includes, extending along its bottom, a number of rounded cavities


24


. As will be discussed, central aperture


22


and its cavities


24


serve to maintain the established horizontal position of wheel


30


.




Base


12


includes two holes


26


that are used for the purpose of mounting hanger


10


of the present invention to a wall, other surface or generally vertical support. In a preferred embodiment, holes


26


are angled slightly downward (from the hanger's front to back) so that two nails are hammered through the holes at an angle (e.g., 45 degree angle) relative to the mounting surface (e.g., wall).




Referring now to wheel


30


, the wheel is circular in shape and includes a set of teeth


32


extending outward along the wheel's perimeter. Teeth


32


are sized and spaced sufficiently apart so that each tooth can be disposed within an opposing recess


14




b


of the locking grooves


14


of base


12


, such as shown in

FIGS. 1 and 2

. Wheel


30


, along with its teeth


32


, is of sufficient size (i.e., diameter) so that when a tooth


32


is disposed within an opposing recess


14




b


, wheel


30


has at least another tooth


32


that is disposed within the longitudinal gap


18


that extends below the base's rim


16


. This also is illustrated in

FIG. 3

, where rim


16


is shown partially in phantom. Moreover, there is sufficient distance between the tooth


32


that is disposed within gap


18


and the hidden end surface


16




a


of rim


16


(

FIG. 3

) so as to allow wheel


30


to be raised upwards (towards surface


16




a


) thus freeing the other tooth


32


from the opposing recess


14




b


of the locking grooves


14


. Then, in such raised position, wheel


30


is freely rotatable. As will be further described below, these features enable for the varying of a picture frame's mounting position after the hanger of the present invention is mounted to a wall.




Referring again to

FIGS. 1 and 2

, and also to

FIG. 4

, a knob


34


is fixed to and extends from wheel


30


and operates as the “hook” on which a picture frame is mounted. As shown in

FIG. 4

, which is a side view of wheel


30


and the attached elements, knob


30


is comprised of a relatively flat, round button-like portion


34




a


coupled to or integral with a narrow stem


34




b


that is fixed to wheel


30


(component dimensions not drawn to scale in FIG.


4


). In the preferred embodiment, both button


34




a


and stem


34




b


of the knob are round in shape and are concentric with one another, so that knob


34


sufficiently is able to retain the wire of a picture frame regardless of the angular position of wheel


30


(further discussed below).




In both

FIGS. 1 and 2

, it is seen that knob


34


is fixed to wheel


30


at a position offset from the wheel's center. Preferably, knob


34


is fixed on wheel


30


at a position that maximizes the knob's vertical movement, which is achieved by fixing the knob on the wheel at a position that is able to come in close proximity to rim


16


(when wheel


30


is rotated), such as shown in FIG.


1


. Then, knob


34


can be positioned adjacent to the locking grooves


14


, adjacent to rim


16


(FIG.


1


), or at any vertical position in between (e.g., FIG.


2


).




To prevent wheel


30


from being fully separated from base


12


, a holding disk


36


is fixed via a locking stem


38


(disk


36


and locking stem


38


may comprise a single element or separate elements) to the rear of wheel


30


, as shown in

FIG. 4

, and during assembly of the picture hanger of the present invention, the holding disk is disposed behind the base with locking stem


38


extending through central aperture


22


.

FIG. 5

is a rear view of the picture hanger and shows disk


36


disposed behind base


12


with wheel


30


disposed in front of the base (locking stem


38


not shown in FIG.


5


). Disk


36


preferably has a diameter D greater than the largest height H of central aperture


22


so that disk


36


is unable to pass through central aperture


22


regardless of the wheel's position relative to the base. However, while it is preferred for disk


36


to be sufficiently large so as to keep wheel


30


and base


12


always together, it is not critical to actually keep these components together when the hanger of the present invention is not in use.




Stem


38


, in addition to coupling disk


36


to wheel


30


, serves as a locking mechanism by being retained within one of the rounded cavities


24


of the central aperture


22


, as shown in

FIG. 6

(in

FIG. 6

, stem


38


shown in phantom, wheel


30


and ridge


40


not shown). Both disk


36


and locking stem


38


are round and concentric to one another, and are concentric to wheel


30


(see FIG.


4


). Locking stem


38


has a diameter of sufficient size so that it is supported by one of the rounded cavities


24


when wheel


30


is fully lowered, that is, when one of the wheel's teeth


32


is disposed within an opposing recess


14




b


of the locking grooves


14


of base


12


. Moreover, the distance between the centers of adjacent cavities


24


is the same as the distance between the centers of adjacent recesses


14




b


(or teeth


14




a


) of locking grooves


14


so that locking stem


38


is accommodated by a respective cavity


24


for each possible horizontal position of wheel


30


. Then, in the lowered position, the peaks


24




a


(shown in

FIG. 6

) of cavity


24


in which locking stem


38


is disposed prevent wheel


30


from moving horizontally. Conversely, when wheel


30


is raised, locking stem


38


is disposed above peaks


24




a


of cavities


24


so that wheel


30


is able to be moved horizontally (longitudinally). In this raised position, wheel


30


and all of its teeth


32


are disposed above locking grooves


14


(

FIGS. 1 and 2

) so that wheel


30


also is freely rotatable, as previously discussed.




Referring again to

FIG. 5

, the rear side of hanger


10


of the present invention includes a ridge


40


that extends along the perimeter of base


12


. Ridge


40


is of sufficient thickness (depth) so that the base's center


20


is disposed slightly away from a wall to which hanger


10


is mounted thus enabling the movement of wheel


30


, more particularly, disk


36


. Ridge


40


needs to be only slightly thicker than disk


36


to ensure a small gap between disk


36


and the wall to which the hanger of the present invention is mounted. That is, without providing a suitably thick ridge


40


, disk


36


is in immediate contact with a wall when hanger


10


is mounted, which in turn would make it difficult to move or turn wheel


30


. Moreover, ridge


40


also extends to the vicinity of holes


26


so that nails can be properly driven and secured to a wall.




To utilize the adjustable picture hanging hook of the present invention, hanger


10


is mounted to a wall in a manner similar to that of prior art devices, namely, hanger


10


is appropriately positioned on a surface onto which it is to be mounted (hereinafter, wall) and suitably sized nails are driven through holes


26


and into the wall thus securing hanger


10


to the wall. Next, the item to be hung (hereinafter, picture frame) is mounted on hanger


10


by, for example, hanging the mounting wire disposed on the rear of the picture frame onto knob


34


. Once mounted, the user determines whether the horizontal and vertical positions of the mounted picture frame are acceptable. If either the vertical or horizontal position is not acceptable or correct, then the picture frame mounting position needs to be adjusted. At this point, in most prior art devices, either the hanger itself will need to be remounted on the wall or the wire attached to the picture will need to be lengthened or shortened.




The present invention, however, allows the picture frame mounting position to be adjusted without remounting the hanger and without changing the length of the wire attached to the picture frame. To adjust the picture frame mounting position, wheel


30


is moved in the manner previously discussed. In particular, if the horizontal position of the picture frame mounting position needs to adjusted, then wheel


30


is manually raised and is moved to the left or right accordingly, without any rotation of the wheel, and then lowered.

FIGS. 1 and 2

show the hanger of the present invention with seven (7) recesses


14




b


(in locking grooves


14


) thus allowing for the placement of the picture frame mounting position in seven horizontal positions. Of course, seven recesses is merely exemplary, and the hanger of the present invention may include any reasonable number of recesses (i.e., horizontal positions). Moreover, additional recesses may be provided without increasing the relative size of the entire hanger itself, simply by reducing the size of each recess


14




b


and tooth


14




a


, as well as by reducing the size of each wheel tooth


32


and increasing the number of such teeth


32


on the wheel (as well as the size and number of rounded cavities


24


within central aperture


22


and the diameter of locking stem


38


).




If the vertical position of the picture frame mounting position needs to be adjusted, then wheel


30


is manually raised and is rotated so that knob


34


is moved upwards or downwards accordingly, and then lowered. Of course, if only the vertical position needs to be adjusted (i.e., the horizontal picture frame mounting position is acceptable), then wheel


30


may need to be moved slightly to the left or right to maintain knob


34


's horizontal position as wheel


30


is rotated. Similarly, if both the vertical and horizontal positions of the picture frame mounting position need to be adjusted, then wheel


30


(after being raised) may be both rotated and moved left or right as needed. Wheel


30


then is lowered and locked in place by both sets of locking devices (i.e., locking grooves


14


and rounded cavities


24


). Adjustment of the picture frame mounting position now has been achieved without remounting the hanger itself.




Referring back to

FIG. 2

, it is seen that it is possible to establish picture frame mounting positions at locations that extend beyond the hanger's support base


12


. Advantageously, the horizontal range of picture frame mounting positions extends past the left and right ends of hanger


10


of the present invention, and the vertical range of picture frame mounting positions extends between the bottom of base


12


to the base's rim


16


. Given such extended horizontal and vertical ranges, the hanger of the present invention allows a user to merely approximate the desired mounting position by mounting the hanger to a wall at such approximated position, and then to select the exact, desired picture frame mounting position by moving wheel


30


in the manner described herein. Moreover, after wheel


30


is locked in place (by lowering it fully), wheel


30


is prevented from moving in any direction and is prevented from rotating, even with the weight of the mounted picture frame on knob


34


, by means of the locking devices previously discussed. Still further, and as previously mentioned, additional mounting positions may be established by increasing the number of teeth


14




a


, recesses


14




b


, wheel teeth


32


, and rounded cavities


24


, and accordingly reducing their size as well as the diameter of locking stem


38


.





FIGS. 7 and 8

of the drawings schematically illustrate a modified design of the wheel and attached hook in accordance with another embodiment of the present invention. Wheel


50


is quite similar to wheel


30


of the design previously discussed. As shown in

FIG. 7

, wheel


50


is circular in shape and includes a set of teeth


52


that extend outward along the wheel's perimeter. As shown in

FIG. 8

, wheel


50


includes a rear stem


54


that extends from its rear center and a disk is attached to the end of stem


54


(disk not shown in

FIG. 8

) similar to disk


36


shown in

FIGS. 4 and 6

. As is appreciated, wheel


50


and each of its components operate in a manner identical to wheel


30


previously discussed.




Wheel


50


further includes a front stem


56


extending off-center from the wheel's front surface. Front stem


56


is similar to stem


34




b


of the previously discussed design shown in

FIG. 4

, except the embodiment shown in

FIGS. 7 and 8

includes a hook portion


60


that is rotatably coupled to stem


56


, and hook portion


60


(or simply hook


60


) operates as the “hook” on which a picture frame is mounted. Hook


60


includes a circular section


60




a


that includes a circular aperture through which stem


56


extends, and a hooked section


60




b


that serves to retain the wire that extends across the rear side of a picture frame (or other suitable item extending from the rear of a picture frame such as a loop or other shape to be held). So that hook


60


may freely rotate about stem


56


, the circular aperture of hook


60


has a diameter that is slightly larger than the diameter of stem


56


. Wheel


50


further includes a trap piece or button


62


attached to the end of stem


56


and serves to retain hook


60


.




In operation, the position of hook


60


relative to the wall to which the hanger of the present invention is mounted is changed in any manner previously discussed. That is, wheel


50


may be moved horizontally relative to base


12


and/or may be rotated. Upon rotation of wheel


50


, hook


60


also rotates to allow the hook section


60




b


to always remain at a proper orientation to retain the picture frame wire. For example, after the hanger of the present invention is mounted to a wall in the manner previously discussed, and after test-mounting of a picture thereon, by retention of the picture's wire by hook


60


, the position of the mount may be modified by removal of the picture, re-positioning of the location of hook


60


(by horizontal movement and/or rotation of wheel


50


), and then re-mounting the picture. Since hook


60


rotates, due to gravity (i.e., the weight of hooked portion


60




b


), when wheel


50


is rotated, the hanger of the present invention always is ready to receive the wire of a picture frame.




The design shown in

FIGS. 7 and 8

provide various advantageous features, in addition to those previously mentioned, that include retention of relatively thick pictures wires and added strength, both due to the use of hook


60


. Moreover, hook


60


appears quite similar to ordinary picture frame hooks so that users readily know on what component of the hanger of the present invention (i.e., hooked portion


60




b


) to place the picture frame's wire.




While the present invention has been particularly shown and described in conjunction with a preferred embodiment thereof, it will be readily appreciated by those of ordinary skill in the art that various changes may be made without departing from the spirit and scope of the invention. For example, the various shapes of teeth


32


, recesses


14




b


, rounded cavities


24


, as well as other components of the hanger, may be different from that shown. For example, teeth


32


and recesses


14




b


may be pointed.




As another example, holes


26


may be provided in different positions than that shown, such as within the base's central portion


20


, with the nails being recessed within ridge


40


so that they do not interfere with the movement of wheel


30


. Also, the hanger of the present invention may be constructed from any suitable material, such as plastic or metal (or other material), with such suitable material being chosen by one of ordinary skill depending on the particular application necessary (e.g., weight of the item to be hung).




As a further example, the embodiment shown in

FIGS. 7 and 8

shows a specific design on which hook


60


is rotatably attached to wheel


50


. However, other known connection techniques also may be used.




Therefore, it is intended that the appended claims be interpreted as including the embodiments described herein, the alternatives mentioned above, and all equivalents thereto.
