Abstract
Abstract A picture hanger is provided with a hook that will wedge-lock a conventional picture hanging cord against movement to maintain the picture in its desired level position. The hook has an open top, open ends, and sidewalls defining an acute angle therebetween converging to a closed bottom that is narrower than the picture hanging cord so that the cord will be pulled by the weight of the picture into wedge-locked relation with the hook and cannot slide or tilt until the weight is lifted.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
168 words
A picture hanger comprising a rigid strip having an upright back, an outturned top leg, a downwardly and inwardly inclined skirt depending from the outer end of the top leg, a first nail hole through the outer end of the leg, a second nail hole through the back adjacent the skirt to receive a nail extending through the first hole, a third nail hole in the lower portion of the back, and an open top, open end continuous planar sidewall wedge hook on the back above the third nail hole, with the planar sidewalls spanning the entire distance between the open ends, whereby a first nail extending through the first and second nail holes is inclined to be driven into a wall at an angle, a second nail extending through the third hole is driven into the wall below the first nail to prevent swinging of the hook on the wall, and said wedge hook friction locks a picture cord therein under the weight of a suspended picture.
Claim 2
Dependent Claim
168 words
A picture hanger comprising a rigid strip having an upright back, an outturned top leg, a downwardly and inwardly inclined skirt depending from the outer end of the top leg, a first nail hole through the outer end of the leg, a second nail hole through the back adjacent the skirt to receive a nail extending through the first hole, a third nail hole in the lower portion of the back, and an open top, open end continuous planar sidewall wedge hook on the back above the third nail hole, with the planar sidewalls spanning the entire distance between the open ends, whereby a first nail extending through the first and second nail holes is inclined to be driven into a wall at an angle, a second nail extending through the third hole is driven into the wall below the first nail to prevent swinging of the hook on the wall, and said wedge hook friction locks a picture cord therein under the weight of a suspended picture.
Claim 3
Dependent Claim
21 words
The hanger of claim 1 wherein the sidewalls of the hook define an acute angle of from 5 to 30 degrees.
Claim 4
Dependent Claim
14 words
The hanger of claim 1 wherein the angle is not more than about 30°.
Claim 5
Dependent Claim
14 words
The hanger of claim 1 wherein the opposed faces of the sidewalls are roughened.
Claim 6
Dependent Claim
40 words
The hanger of claim 1 wherein the sidewalls of the hook are formed by the upright back of said rigid strip and a separate strip welded to said back and said strips having widths of about 1/8 to 1/2 inch.
Claim 7
Dependent Claim
165 words
A picture hanger comprising a rigid strip having an upright back portion with a flat planar front face, a nail hole through said back at the upper end thereof for securing said strip to a wall, a second rigid planar strip portion having an upright bottom leg overlying said flat front face of said back with an outturned top leg diverging from said front face at an acute angle, said outturned leg having a flat planar inner face confronting the front face of the back to define therewith an open top open ended hook with planar sidewalls extending continuously between the open ends and converging to a closed bottom edge which is too narrow to bottom a picture cord whereby the cord will be wedge-locked against sliding without being kinked when pulled downwardly into the hook by the weight of a picture and will be released to the open top of the hook when lifted for permitting sliding to adjust the level of the picture.
Claim 8
Dependent Claim
165 words
A picture hanger comprising a rigid strip having an upright back portion with a flat planar front face, a nail hole through said back at the upper end thereof for securing said strip to a wall, a second rigid planar strip portion having an upright bottom leg overlying said flat front face of said back with an outturned top leg diverging from said front face at an acute angle, said outturned leg having a flat planar inner face confronting the front face of the back to define therewith an open top open ended hook with planar sidewalls extending continuously between the open ends and converging to a closed bottom edge which is too narrow to bottom a picture cord whereby the cord will be wedge-locked against sliding without being kinked when pulled downwardly into the hook by the weight of a picture and will be released to the open top of the hook when lifted for permitting sliding to adjust the level of the picture.
Claim 9
Dependent Claim
186 words
A picture hanger comprising a rigid metal strip having an upright back with a flat planar front face, an outturned top leg, a downwardly and inwardly inclined skirt depending from the outer end of the top leg, a first nail hole through the outer end of the leg, a second nail hole through the back adjacent the skirt to receive a nail extending through the first hole for securing the hanger to a wall in upright position, a second flat planar strip having an upright bottom leg welded to the bottom portion of said front face and an integral outturned top leg diverging from said front face and having a back face cooperating with the front face of the back to define therewith the flat planar sidewalls of an open top open end hook converging to a closed bottom edge which is too narrow to bottom a picture cord whereby said hook frictionally locks a picture cord between the sidewalls under the weight of a suspended picture and frees the cord to the open top of the hook when the weight of the picture is released.
Claim 10
Dependent Claim
186 words
A picture hanger comprising a rigid metal strip having an upright back with a flat planar front face, an outturned top leg, a downwardly and inwardly inclined skirt depending from the outer end of the top leg, a first nail hole through the outer end of the leg, a second nail hole through the back adjacent the skirt to receive a nail extending through the first hole for securing the hanger to a wall in upright position, a second flat planar strip having an upright bottom leg welded to the bottom portion of said front face and an integral outturned top leg diverging from said front face and having a back face cooperating with the front face of the back to define therewith the flat planar sidewalls of an open top open end hook converging to a closed bottom edge which is too narrow to bottom a picture cord whereby said hook frictionally locks a picture cord between the sidewalls under the weight of a suspended picture and frees the cord to the open top of the hook when the weight of the picture is released.
Claim 11
Dependent Claim
16 words
The picture hanger of claim 6 wherein the acute angle is not more than about 30°.
Claim 12
Dependent Claim
33 words
The picture hook of claim 6 wherein the planar front face of the upright back and the confronting inner face of the outturned leg have a width of about 1/8 to 1/2 inch.
Claim 13
Dependent Claim
35 words
The picture hanger of claim 6 wherein the bottom leg of the second rigid planar strip portion is welded to the front face of the upright back adjacent the closed bottom edge of the hook.
Claim 14
Dependent Claim
28 words
The picture hanger of claim 6 wherein the inner face of the outturned top leg and the front face of the back opposite said inner face are roughened.
