Description

wall mount

technical field

The present invention relates to wall hangings for hanging objects supported on a wall, such as photographs, mirrors, paintings and the like. More particularly, the present invention relates to means for quickly and efficiently hanging such items on a wall at a desired height or orientation.

For the purpose of simplifying the description, the present invention is introduced here by taking the figure as an example. However, it should be understood that the term "figure" is used to generally include any item that needs to be hung or mounted on a wall or other essentially vertical surface, such as paintings, photographs, wall clocks, pictures, mobile phones, calculators, and the like.

Background technique

For many people, hanging a photo at a desired height and at a desired distance from other photos or objects is by no means a simple job or a chore. Driving a nail to the wall, or fixing the photo hook on the wall itself is simple, but there is some kind of secret around whether the position of the nail is appropriate, in order to ensure that the photo is at an appropriate height when hanging on the hook, and the spatial orientation of the wall appropriate.

One often does it by trial and error, and finally achieves the desired result, but always punches holes in the wall. This approach is clearly not the most desirable, both aesthetically and practically. To overcome the inherent disadvantages of this approach, many solutions have been proposed.

For example, see US Patent Nos. 4,645,165, 4,455,756, 5,520,318, 5,437,429, and 3,945,599.

U.S. Patent No. 2530892 (Mayo) discloses a photo hanger comprising two components, one fixed to the wall and the other to the picture frame - including coplanar ones with interfitting arched faces in only one plane member, and has limited rotational capability, limited frictional clamping between the two components.

German Patent Publication No. DE3632819A (Biener) discloses a two-component photo hanger, one of which has a tapered plug which mates with a corresponding receiving frame on the other. When the plug and receiving frame are mated together, there is no rotational capability to adjust one assembly relative to the other.

French Patent Publication No. FR2422369A (Profiver) discloses a tapered cooperating two-component photo hanger, which, after it is mounted on the wall, also does not have the ability to adjust the rotation of one of the two components relative to the other, so as to facilitate Then straighten the photo. Likewise, U.S. Patent No. 4340195 (Brock) also discloses a kind of photo hanger, and it is made up of two mutually clamped parts, and they can slide mutually, but can't rotate and adjust.

Australian petty patent AU718053 (Klaesi) discloses a photo hanging device consisting of two parts, one part is used to be fixed on the wall, the second part is fixed on the photo or other items to be mounted on the wall, the first and second parts Contains coplanar members, in each of two axially separated and parallel planes, the coplanar members having cooperating arcuate contact surfaces that allow one of the two parts (and the fixed photograph) to be positioned relative to the The other part and the relative wall make left and right limited rotation adjustments. However, the degree or range of rotation is limited to less than 90° left and right (not more than 70° in practice).

Hanging pictures is usually done by a person supporting the picture on the wall with both hands, checking the desired position of the picture, and marking the desired position on the wall with a pencil or similar. Then estimate the position of the hook, so that the hook can be installed, and the hook will support the slack across the picture wire hanging on the back of the picture, so that the picture is placed at or close to its desired position. Nails or screws or a hooking arrangement comprising a fastener such as a nail or staple and a hook are then mounted to the wall by nailing the fastener to the wall. Finally, place the photo against the wall and control it, so the photo wire travels down and catches on the hook. These steps will take some time for both amateurs and experts, especially when a large number of photos are to be hung. Therefore, hanging photos can be a very laborious and time-consuming thing.

Another problem is that the photos are not always in the desired position due to the difficulty in estimating the effect of the bending of the photo lines and the overhang of the top edge of the photo from the wall.

The photographs are usually hung on the wall by means of a cord, thread or similar means which hangs through the anchor holes on the opposite side of the back of the picture frame, the cord or thread being suspended from one or more hooks embedded in the wall. Attaching cord or thread to the back of a photo, especially in a clean, unobtrusive and reliable manner, can be difficult. There may also be difficulty moving the cord or line along the hook.

It would be useful to have a photo hanging device that allows a photo to be hung with only one positioning, especially if a large number of photos are to be hung and the user has limited photo hanging operations or skills. For hanging other items, the ability to rotate the hanging device relative to the wall is more desirable.
