Description
Background of the Invention
1. Field of the Invention
The present invention relates generally to hanger devices and, more particularly, to devices especially adapted for hanging pictures and the like on vertical surfaces such as walls.
2. Description of the Prior Art
It is common practice in homes and offices to hang pictures and the like on vertical surfaces such as walls. Commonly, a portion of a nail or screw is driven into a wall at an acute angle leaving another portion of the nail or screw projecting from the wall. A picture frame, that has a cord or wire attached, is hung by the cord or wire on the portion of the nail or screw that projects from the wail. This simple approach to hanging picture on a wall has a number of disadvantages.
When a picture is hung on a wall, it is often desired that the picture be located at a precise location on the wall. However, because a cord or wire is flexible it is often difficult to know exactly where to drive the supporting nail or screw into the wall so that the picture, when hanging from the cord or wire, will be positioned on the wall at the precise location on the wall that is desired. In this respect, it would be desirable if a picture hanging device were provided which does not employ a flexible cord or wire for hanging the picture on a wall.
After a supporting nail or screw is driven into a wall and after the picture is hung by a flexible cord or wire from the supporting nail or screw, it may be observed that the actual location of the picture on the wall is either higher than or lower than the desired location on the wall. As a result, the supporting nail or screw must be removed from the wall leaving a hole, and the nail or screw must be driven into a location that is either higher or lower than the initial position. The picture may be rehung from the supporting nail or screw at the second position on the wall and may still be at an undesirable location on the wall. This process of trial and error may result in a number of undesirable holes arrayed vertically in a wall. In this respect, it would be desirable if a picture hanging device were provided which did not require a process of trial and error potentially resulting in a number of improperly vertically located holes in a wall.
When a picture is hung on a wall, its vertical positioning is not the only important positioning criteria. For proper picture positioning, the picture must be properly located horizontally as well. When a wall-supported nail or screw and a picture that employs a cord or wire are employed, it may be difficult to properly locate the picture horizontally on the wall without resorting to a number of horizontally arrayed unwanted holes necessitated by trial and error. In this respect, it would be desirable if a picture hanging device were provided which does not require a process of trial and error potentially resulting in a number of improperly horizontally located holes in a wall.
Throughout the years, a number of innovations have been developed relating to objects, including pictures, from vertical surfaces, and the following U.S. patents are representative of some of those innovations: U.S. Pat. Nos. 1,172,937; 2,317,368; 4,407,478; 4,557,455; 4,568,055; and 4,728,237. More specifically, U.S. Pat. No. 1,172,937 discloses article hangers that are suspended from a flexible strap or chain. The disadvantages of a flexible cord or wire for suspending a picture have been discussed hereinabove. U.S. Pat. No. 2,317,368 discloses a picture hook which is employed with a flexible cord or wire for suspending a picture.
U.S. Pat. No. 4,407,478 discloses a J-shaped pipe hanger that receives a pipe with a snap fit. In order for a snap fit to be implemented, either the pipe or the hanger must be sufficiently flexible to permit a snap connection between the two. Requiring such a snap fit places burdensome restrictions of the types of materials that can be employed in fabricating the pipe and the pipe holder. In this respect, it would be desirable if a picture hanging device were provided which does not require a snap fit and which, therefore, is not severely restricted in the kinds of materials that can be employed in fabricating the hanger apparatus.
U.S. Pat. No. 4,557,455 discloses a hanging apparatus which includes a flexible tongue to lock against a serrated strip. This device permits vertical adjustment, but it does not provide for horizontal adjustment.
U.S. Pat. No. 4,568,055 discloses serrated corner braces attached to respective corners of a picture frame. These corner braces can be supported by respective support nails or screws driven into a wall. Yet, the corner braces do not permit vertical or horizontal repositioning of the location of the picture on the wall unless the respective locations of the support nails or screws are changed vertically or horizontally. In this respect, it would be desirable if a picture hanging device were provided which does not require readjusting support nails or screws vertically or horizontally in order to readjust the vertical and horizontal position of a picture supported by the support nails or screws.
U.S. Pat. No. 4,728,237 discloses a picture frame hanger that is driven into a picture frame. The hanger has an aperture that fits around a support nail. This hanger does not permit vertical or horizontal adjustment of the picture frame on the wall without relocation of a support nail.
U.S. Pat. No. 4,343,450 may be of interest for its disclosure of a plate holder whose intended purpose is to hold a plate at a desired tilt angle on a horizontal surface.
Thus, while the foregoing body of prior art indicates it to be well known to use wall-mounted nails to hang pictures on a wall, the prior art described above does not teach or suggest an adjustable hanger apparatus which has the following combination of desirable features: (1) does not employ a flexible cord or wire for hanging a picture on a wall; (2) does not require a process of trial and error resulting in a number of improperly vertically located holes in a wall; (3) does not require a process of trial and error resulting in a number of improperly horizontally located holes in a wall; (4) is not severely restricted in the kinds of materials that can be employed in fabricating the hanger apparatus; and (5) does not require readjusting support nails vertically or horizontally in order to readjust the vertical and horizontal position of a picture supported by the support nails. The foregoing desired characteristics are provided by the unique adjustable hanger apparatus of the present invention as will be made apparent from the following description thereof. Other advantages of the present invention over the prior art also will be rendered evident.

With reference to the drawings, a new and improved adjustable hanger apparatus embodying the principles and concepts of the present invention will be described.
Turning to FIGS. 1-4, there is shown a first exemplary embodiment of the adjustable hanger apparatus of the invention generally designated by reference numeral 10. The adjustable hanger apparatus 10 is provided for hanging an object 12 on a vertical surface 14 and includes a first hanger assembly 16 for mounting on the vertical surface 14 and a second hanger assembly 18 for mounting on the object 12. The first hanger assembly 16 includes a first connector portion 22. The second hanger assembly 18 includes a longitudinal axis 20 and includes a plurality of second connection portions 24 arrayed along the longitudinal axis 20. The second connection portions 24 are adapted to connect to the first connector portion 22 of the first hanger assembly 16, such that, when a selected second connection portion 24 is connected to the first connector portion 22, the object 12 hangs by the second hanger assembly 18 and the first hanger assembly 16 next to the vertical surface 14.
The first hanger assembly 16 has a first width 26; the second hanger assembly 18 has a second width 28; and the first width 26 is greater than the second width 28. With the first width 26 being greater than the second width 28, the second hanger assembly 18 can be moved horizontally with respect to the first hanger assembly 16, whereby the object 12 attached to the second hanger assembly 18 can be positioned horizontally along the first hanger assembly 16 that is connected to the vertical surface 14.
The first hanger assembly 16 includes a pair of fastener-receiving portions 30 located at opposite ends of the first hanger assembly 16. A first connector portion 22 is located between the fastener-receiving portions 30. Each of the fastener-receiving portions 30 includes a rear wall 70 and a channel 52 for receiving a fastener such as a nail 50. The rear wall 70 and the channel 52 are oriented with respect to each other at a first predetermined acute angle 72. The first predetermined acute angle 72 is in a range spanning thirty to sixty degrees. The first predetermined acute angle 72 may be approximately forty-five degrees.
The first connector portion 22 includes a tongue 34 that projects outward from the first hanger assembly 16. Each of the second connection portions 24 of the second hanger assembly 18 includes a ridge portion 36 and a groove portion 38. The first hanger assembly 16 includes a well portion 32 located adjacent to the first connector portion 22. The well portion 32 is adapted to receive the ridge portion 36 of a selected second connection portion 24. The fastener-receiving portions 30 of the first hanger assembly 16 serve as barriers which prevent the ridge portion 36 of the selected second connection portion 24 from sliding off out of the well portion 32.
The well portion 32 includes a first inner wall 80 and a second inner wall 82 which are oriented with respect to each other at a second predetermined acute angle 84. The ridge portion 36 includes a front wall 86 and a rear wall 88, and the front wall 86 and the rear wall 88 of the ridge portion 36 are oriented with respect to each other at a third predetermined acute angle 90. The third predetermined acute angle 90 is less than or equal to the second predetermined acute angle 84, whereby the ridge portion 36 is capable of fitting into the well portion 32 with a tight fit.
In using the adjustable hanger apparatus 10 of the invention to hang the object 12, e.g. a picture, on the vertical surface 14, e.g. a wail, the first hanger assembly 16 is first attached to the vertical surface 14. Nails 50 are placed through channels 52 in the fastener-receiving portions 30 of the first hanger assembly 16 and are driven into the vertical surface 14. Alternately, screws can be used in place of the nails 50. The second hanger assembly 18 is attached to the back of the object 12 by using a screw 54 that is passed through a fastener-receiving channel 56 in the second hanger assembly 18.
The fastener-receiving channel 56 in the second hanger assembly 18 includes a first portion 58 which has a first width 60 and a second portion 62 which has a second width 64. The first width 60 is greater than the second width 64. Moreover the screw 54 is selected so that the diameter of the head of the screw 54 is less than the first width 60 and greater than the second width 64. In this way, the head of the screw 54 can be pressed up against a ledge 66 and press the second hanger assembly 18 against the object 12 when the screw 54 is screwed into the object 12.
With the second hanger assembly 18 attached to the vertical surface 14 and with the first hanger assembly 16 attached to the vertical surface 14, a person grasps the object 12 and places a selected groove portion 38 of the second hanger assembly 18 over the tongue 34 of the first hanger assembly 16. Then, the person releases the object 12 permitting gravity to pull the groove portion 38 over the tongue 34, whereby the object 12 hangs on the vertical surface 14. At the same time the tongue 34 enters the groove portion 38, the ridge portion 36 of the second hanger assembly 18 enters the well portion 32 of the first hanger assembly 16, whereby the connection between the second hanger assembly 18 and the first hanger assembly 16 is stabilized.
Vertical adjustment of the object 12 on the vertical surface 14 is obtained by appropriate selection of a specific groove portion 38 and ridge portion 36 of the second hanger assembly 18 along the longitudinal axis 20 to be placed in registration with the tongue 34 and the well portion 32 of the first hanger assembly 16, respectively. With the ridge portion 36 of the second hanger assembly 18 in the well portion 32 of the first hanger assembly 16, the second hanger assembly 18 can be moved horizontally along the well portion 32 to provide a horizontal adjustment of the object 12 on the vertical surface 14. The fastener-receiving portions 30 of the first hanger assembly 16 have inside walls 78 which serve as stops or limits to horizontal movement of the ridge portion 36 in the well portion 32.
Turning to FIGS. 5-7, a second embodiment of the invention is shown. Reference numerals are shown that correspond to like reference numerals that designate like elements shown in the other figures. In addition, the first hanger assembly 16 includes a double-nail assembly 40 adapted to be driven in the vertical surface 14. The double-nail assembly 40 includes a pair of nail portions 42, and a transverse bar portion 44 is connected between the nail portions 42. The transverse bar portion 44 serves as the first connector portion 22 of the first hanger assembly 16 for connecting to the second connection portion 24 of the second hanger assembly 18.
More specifically, the transverse bar portion 44 of the double-nail assembly 40 readily fits into a selected groove portion 38 of the second hanger assembly 18, whereby the object 12 is supported on the vertical surface 14 by way of the nail portions 42 driven into the vertical surface 14, the transverse bar portion 44 supported by the double-nail assembly 40 and projecting outward from the vertical surface 14, the selected groove portion 38 of the second hanger assembly 18 which receives the transverse bar portion 44, the body of the second hanger assembly 18, and a screw 48 which secures the second hanger assembly 18 to the object 12.
The components of the adjustable hanger apparatus of the invention can be made from inexpensive and durable metal or plastic materials, plastic materials being preferred.
As to the manner of usage and operation of the instant invention, the same is apparent from the above disclosure, and accordingly, no further discussion relative to the manner of usage and operation need be provided.
It is apparent from the above that the present invention accomplishes all of the objects set forth by providing a new and improved adjustable hanger apparatus that is low in cost, relatively simple in design and operation, and which may advantageously be used without employing a flexible cord or wire for hanging a picture on a wall. With the invention, an adjustable hanger apparatus is provided which does not require a process of trial and error resulting in a number of improperly vertically located holes in a wall. With the invention, an adjustable hanger apparatus is provided which does not require a process of trial and error resulting in a number of improperly horizontally located holes in a wall.
