Abstract
An adjustable length over-the-door hanger for hanging a wreath or other hanging objects on a door whose length can be adjusted to position the hanging object at the desired height. The hanger is made of two vertical supports that are held together and where the lower vertical support can slide along the upper vertical support to lengthen or shorten the overall length of the hanger. A track on one support is engaged by a finger on the other support thereby allowing the hanger to be locked into any one of a number of fixed positions corresponding to the desired height for the wreath to be hung on the door. This positioning allows the hanger to be easily adjusted while in place on the door. The hanger has a hook that allows it to hang over the top of the door and another hook at the bottom on which the hanging object can be hung.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to over-the-door hangers and, more particularly, to an over-the-door hanger that has an adjustable overall length in order to hang objects at various heights.
2. Description of Related Art
Over-the-door hangers have been used for a number of years. The basic structure generally includes a metal or piece of molded plastic that can be hung over the top of a door and extends down the face of the door, terminating in a hook used to support the item being hung. The advantage of these hangers is that items such as wreaths can be hung without the need to permanently attach anything to the door. This is especially useful for hanging seasonal items such as a wreath that is only hung on the door for a relatively short period of time during the year.
However, these hangers are of fixed length. Depending on what is being hung on the door and the height desired a user needs either to have a number of hangers of different lengths or to know the exact length desired before purchasing the hanger. In addition, with hangers only made in certain lengths, there is no way to conveniently hang an object at an intermediate height.
More recently over-the-door hangers have been made that have an adjustable length to hang an object at a desired height. One such hanger has two vertical pieces, one having a single, rearward-facing projection that engages a set of forwardly facing detent structures on the other piece. Adjusting the length of the hanger requires manually bending the two pieces apart so as to disengage the rearward facing projection from the recess in the other vertical piece and then slide the vertical pieces at the same time.
It is often desirable to adjust the length of the hanger once it has already been placed upon the door. Therefore, there is a need for an adjustable length over-the-door hanger that can be easily adjusted while in position on the door.
SUMMARY OF THE INVENTION
The subject invention comprises an adjustable over-the-door hanger. The subject hanger allows the user to adjust the overall length of the hanger so that the lower hook upon which an object is hung can be placed at a desired height for hanging the object. The subject hanger is made up of two vertical supports that slide along each other to either shorten or lengthen the overall length of the hanger. A door hook on the top of the upper vertical support hooks over the top of the door and secures the hanger to the front of the door. There is also a lower hook at the bottom of the lower vertical support upon which the desired object can be hung. At the bottom of the upper vertical support, an enclosure wraps around the lower vertical support and prevents it from moving out of slidable contact with the upper vertical support. Along one of the sides of the upper vertical support there is an engagement track and along the opposite side there is a support track. At the top of the lower vertical support there are two finger projections. An engagement finger selectively engages the engagement track on the upper vertical support to prevent the lower vertical support from sliding downwardly relative to the upper vertical support. On the opposite side from the engagement finger is a support finger that has a support groove through which the support track runs. The support finger keeps the upper vertical support in slidable contact with the lower vertical support and prevents it from moving away from the engagement finger. Because the engagement finger and engagement track are located on the side of the vertical supports, it can easily be disengaged for adjustment while the adjustable over-the-door hanger is in place on a door.
In a preferred embodiment, the engagement track is made up of teeth and the engagement finger contains corresponding teeth that are able to seat in between the track teeth and prevent the lower vertical support from sliding further down. The teeth provide discrete adjustment points and allow the hanger to support a greater amount of weight than if the engagement track was a flat surface frictionally engaged by the engagement finger. The engagement finger is preferably resiliently biased to engage the engagement track. This allows the hanger to be in a locked configuration at all times that it is not being adjusted. The support track is preferably thinner than the upper vertical support allowing the support track to fit in the support groove of the support finger. The upper vertical support so that the upper vertical support will preferably lie flat against the front surface of the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIG. 1
, the adjustable length over-the-door hanger
20
comprises an upper vertical support
22
and a lower vertical support
24
. The back face of lower vertical support
24
is slidably connected to the front face of upper vertical support
22
. When lower vertical support
24
slides down upper vertical support
22
, the overall length of adjustable length over-the-door hanger
20
increases. Sliding lower vertical support
24
up along upper vertical support
22
shortens the overall length of adjustable length over-the-door hanger. Door hook
28
is integrally molded or otherwise attached to the top of upper vertical support
22
and lower hanger
26
is integrally molded or otherwise attached to the bottom of lower vertical support
24
. Upper vertical support
22
has an engagement track
36
on one side of upper vertical support
22
. Engagement finger
38
is disposed at the top of lower vertical support
24
. As shown in
FIG. 1
, engagement finger
38
engages track teeth
40
, which make up engagement track
36
located on one side of upper vertical support
22
. Support finger
46
is disposed on the opposite side of the top of lower vertical support
24
from engagement finger
38
. A support groove
60
, best shown in
FIG. 3A
, is formed integrally with support finger
46
and is configured for the slidable reception of support track
48
. Finally enclosure
34
is disposed at the bottom of upper vertical support
22
. Enclosure
34
and support finger
46
maintain upper vertical support
22
and lower vertical support
24
in slidable alignment and in a position where engagement finger
38
can engage engagement track
36
.
Referring to
FIGS. 2 and 3
, lower hanger
26
is located at the bottom of lower vertical support
24
. Lower hanger
26
is formed by integrally molding the lower end of lower vertical support
24
in a curled circular shape. The exact size and shape of the lower hanger can vary depending on what object is desired to be hung on the door.
As shown more clearly in
FIGS. 2A and 3A
, engagement finger
38
and support finger
46
are disposed at the top of lower vertical support
24
. Engagement finger
38
contains finger teeth
44
which are cooperatively engageable with track recesses
42
between track teeth
40
on engagement track
36
as shown more clearly in FIG.
7
. Engagement finger
38
is made of a resilient material and is biased to a position where finger teeth
44
remain engaged with track teeth
40
. This prevents lower vertical support
24
from sliding any further down upper vertical support
22
. Engagement finger
38
can be digitally deformed to pull finger teeth
44
away from track teeth
40
, thereby disengaging engagement finger
38
from engagement track
36
. This allows lower vertical support
24
to slide along upper vertical support
22
and the overall length of adjustable length over-the-door hanger
20
to be changed as desired. Releasing pressure from engagement finger
38
will allow it to return to its original position and reengage with engagement track
36
, resulting in lower vertical support
24
being locked into a new configuration compared to upper vertical support
22
.
Referring to
FIGS. 4 through 8
, door hook
28
is attached at the top of upper vertical support
22
. Door hook
28
is made up of horizontal piece
30
and vertical piece
32
. Horizontal piece
30
is perpendicular to upper vertical support
22
and is thin enough to fit over the top of the door and not substantially hinder the closing of the door. Vertical piece
32
is desirably inwardly biased to frictionally engage the back surface of the door. This can be achieved as shown in
FIG. 5
where vertical piece
32
is attached to horizontal piece
30
at somewhat less than ninety degrees. Vertical piece
32
is preferably made out of a resilient semi-flexible material such as plastic. Door hook
28
can also optionally have decorative hook
50
on the end of vertical piece
32
, thereby allowing an additional item to be hung on the inside of the door.
As shown more clearly in
FIG. 7
, enclosure
34
is disposed at the bottom of upper vertical support
22
. Enclosure
34
wraps around lower vertical support
24
and allows lower vertical support to slide freely through and maintains slidable contact between upper vertical support
22
and lower vertical support
24
. In the embodiment shown the enclosure is formed by two ‘L’ shaped pieces
56
, one of which is rotated 180 degrees and connected by two posts
58
at each end of the ‘L’ so that one ‘L’ is higher than the other is. This is not the only configuration possible and enclosure
34
could, for example, be a single band wrapped around lower vertical support
24
. Enclosure
34
also does not have to wrap entirely around lower vertical support
24
as long as it can maintain lower vertical support
24
in slidable contact with upper vertical support
22
by preventing the lower vertical support
24
from moving to either side and from lifting off upper vertical support
22
.
Upper vertical support
22
has engagement track
36
on one of its vertical edges and support track
48
on the other vertical edge. Support track
48
is preferably thinner than the upper vertical support
22
, thereby allowing support track
48
to be slidably received by support groove
60
. As shown more clearly in
FIG. 7
, engagement track
36
is made up of track teeth
40
and the spaces between individual teeth are track recesses
42
. Track teeth
40
have a horizontal top face
64
and a sloping bottom face
62
. Finger teeth
44
have a shape matching track recess
42
. Therefore finger teeth
44
have a sloping top face cooperatively aligned and engageable with sloping bottom face
62
of track teeth
40
and a horizontal bottom face cooperatively aligned and engageable with horizontal top face
64
of track teeth
40
.
When engaged with the corresponding finger teeth
44
on engagement finger
38
, the flat surfaces of finger teeth
44
and track teeth
40
are in contact and prevent lower vertical support
24
from sliding down upper vertical support
22
. The sloping side of the track teeth
40
and finger teeth
44
allow finger teeth
44
to properly seat themselves in between track teeth
40
when an object is hung from the lower hanger. The number of possible height adjustments and the distance between successive adjustment points are determined by the size of and distance between the teeth. Smaller incremental adjustments in the overall length of adjustable length over-the-door hanger
20
are possible when track teeth
40
and finger teeth
44
are closer together and smaller. However, smaller teeth may prevent adjustable length over-the-door hanger
20
from supporting heavier objects on the door. Therefore, the teeth size should be determined based upon the degree of support and adjustability that are desired.
FIG. 9
shows the adjustable length over-the-door hanger
20
in use on door
52
. As shown in dashed outline, adjustable length over-the-door hanger
20
originally was in an upper position to allow an object to be hung higher up on door
52
. Lower hook
26
′, lower vertical support
24
′ and engagement finger
38
′ show the position of the lower vertical support in the first position. When engagement finger
38
′ is disengaged from engagement track
36
and lower vertical support
24
′ is slid down along upper vertical support
22
a second lower position is reached. At this point pressure is removed from engagement finger
38
and it is allowed to reengage with engagement track
36
. This serves to lock lower vertical support
24
into its new lower position. In this position lower hook
26
is lower than its original position
26
′ allowing an object to be hung lower down on door
52
.
Other alterations and modifications of the preferred embodiment described above will become apparent to those of ordinary skill in the art upon reading this disclosure, and it is intended that the scope of the invention disclosed herein be limited only by the broadest interpretation of the appended claims to which the inventor is legally entitled.
