Abstract
A picture hanging system comprised of a horizontally extending rail attached to the upper portion of a wall on which pictures are to be displayed. Said rail is spaced a precise horizontal distance away from the wall. Visual exposure of the rail and associated hardware can be eliminated by covering it with a decorative moulding that is quickly and easily attached. Cable assemblies can be quickly and easily connected at any desired location on the rail with the associated small diameter cables extending vertically downward. One or more clamp and hook assemblies can be directly attached to the cables at any point on the cable. The pictures are then hung from the hooks. If re-positioning of the pictures is required this can be done quickly and easily. With pictures installed the system achieves the highest possible aesthetic standards by virtue of the fact that only the molding and the very small diameter cables are visible.
Description
- This is a continuation-in-part of U.S. patent application Ser. No. 10/424,153, filed Apr. 25, 2003, which claims the benefit of U.S. provisional patent application Ser. No. 60/375,672, filed Apr. 26, 2002.
- This invention relates to picture hanging systems and more particularly to a system that permits quick and easy placement of pictures on walls at desired locations while minimizing wall damage.
- A picture is normally suspended from its hanging wire by a single hook that is fastened to the wall by a nail. A well-known problem arises in installing the picture in the exact desired location on the wall when using the above noted method. Typically the hook is first installed on the wall at a location judged to be approximately correct. The picture is then hung and a determination is made as to where to relocate the hook to achieve a placement closer to the desired location. This trial and error method may involve several repetitions until the exact desired location is obtained. It is also noisy, time consuming and damages the wall due to the multiple nail holes that are created. The problem becomes particularly acute in art galleries where numerous pictures are displayed on the walls, which are frequently replaced or moved.
- Various picture-hanging systems have been developed, such as disclosed in Schuite, U.S. Pat. No. 4,973,021; Hayde, U.S. Pat. No. 5,878,987; Keers, U.S. Pat. No. 5,992,813 and Fleishman, U.S. Pat. No. 6,119,999, which are particularly for use in galleries, to overcome the above noted problems. Such systems however suffer from one or more of the following impediments.
- First, tools are often required to hang the pictures. Second, typically, additional pictures cannot be installed in the same area without first removing existing pictures and their associated hangers and then re-installing them. Thirdly, the picture hook cannot be directly connected to the cable that supports the artwork. Rather, the cable has to be fed through the hook until the hook reaches its intended location on the cable. This is often time consuming and cumbersome. Fourthly, the cable hook can impart kinking on the support cable which, if exposed by later moving the picture can be unsightly. Fifthly, the systems typically use specialized equipment which can be costly to manufacture, and difficult to install.
- There is therefore a need for a picture hanging system, which overcomes some, or all of the above identified shortcomings.
- The instant exemplary embodiments provide an adjustable, inexpensive, and easy to install track-based picture hanging system.
- Some embodiments provide a low cost, unobtrusive, aesthetically appealing, adjustable picture hanging system that allows quick, quiet, easy and precise placement of pictures at numerous locations on a wall, is easily and quickly adjustable and does not require special skills or tools to operate. Some embodiments utilize standard commercially available components for parts of the system.
- Some embodiments provide a system having a rail mounted horizontally near the top of a wall section, a cable suspended from the rail and a combination clamp and picture hook that can be directly engaged and clamped from the side to the cable. In some embodiments the clamp and picture hook is tightened or loosened on the cable by an integral thumbscrew incorporated in the assembly thereby precluding the need for any tools. In some embodiments the clamp and picture hook assembly can be quickly attached or detached from the lengths of a cable at any time without affecting other pictures already hanging on the cable or on other adjacent cables on the wall.
- When installing a picture the cable is first connected to the rail at the approximate desired horizontal location on the wall. Next the clamp and hook assembly is installed on the cable at the approximate desired vertical location on the wall. The picture is hung and a determination is made if it is necessary to shift it vertically and/or horizontally. If a change in location is necessary the desired position is readily achieved by moving the clamp and hook assembly vertically on the cable lengths and/or by moving the point of cable to rail attachment horizontally.
- In some embodiments two clamp and hook assemblies can be employed for each picture, spaced apart horizontally in cases where the picture is very heavy, or where it is desired to eliminate any possible lateral movement of the picture on the wall, or where additional support redundancy is deemed necessary.
- In some embodiments there is provided a system for hanging a picture on a wall, said system comprises: a rigid support member comprising an elongate ledge terminating at a rear edge; said member being secured to said wall so that said edge is substantially parallel with and spaced apart from said wall, thereby forming a gap between said edge and said wall; a clip comprising: a backing portion having a first substantially planar surface oriented to bear against said wall; a prong portion extending from said backing portion at a first angle; and, said prong portion having a first dimension greater than said gap and a second dimension narrower than said gap, whereby said prong portion passes through said gap in a first orientation and will not pass through said gap in a second orientation; and, means for releasably mounting said picture to said clip.
- In some embodiments, said first orientation relates to said second orientation by a rotation angle commensurate with said first angle. In some embodiments, said clip further comprises a spring arm resiliently connected to said backing portion and oriented to bear against one of a pair of opposing surfaces formed between said wall and said member. In some embodiments, said spring arm is oriented to bear against said edge. In some embodiments, said prong portion and said backing portion form a substantially L-shaped structure. In some embodiments, said spring arm comprises a substantially L-shaped structure dimensioned to nest within said prong portion and said backing portion. In some embodiments, said prong portion connects to said backing portion at a rounded bend.
- In some embodiments, said means for releasably mounting comprise: a length of cable having first and second end portions, and a medial portion between said end portions; said first end portion being secured to said clip; a picture hook clamp assembly releasably secured to said medial portion. In some embodiments, said assembly comprises a generally U-shaped body member comprising: first and second clamping plates connected by an apex; said plates being frontwardly spaced apart a first distance; said second plate having a first angled projection thereby forming a picture hook; said body member having opposite lateral edge portions; and, said body defining a substantially vertical centerline. In some embodiments, said clamp further comprises an adjustable fastener engaging said clamping plates, said fastener being actuated to adjust said first distance. In some embodiments, said fastener comprises a screw bonded to said first plate and penetrating opposing drillings through said plates and engaging a wing nut. In some embodiments, said body member is shaped to have a cutout extending medially along said apex from a lateral edge and terminating at a stop surface beyond said centerline of said clamp. In some embodiments, said screw is located to have a lateral surface substantially vertically in line with said stop surface, thereby providing two contact points upon which said cable is centered.
- In some embodiments, said rigid support member consists of a standard commercially available slotted bookshelf mounting rail.
- In some embodiments the system further comprises a spacer having a thickness determining said gap. In some embodiments, said spacer comprises first and second concentric and adjacent washers, wherein said first washer is formed to have a centerhole having a first diameter and said second washer is formed to have a centerhole having a second diameter, and wherein said first diameter is larger than said second diameter.

FIGS. 1-4 the horizontal deployment of a rigid support member orrail 1 to which the cables are connected on a typical section ofwall 2. The rail is a standard commercially available slotted bookshelf mounting rail generally used in book shelving systems that can be purchased in varying lengths in most hardware stores. The rail has a generally U-shaped cross-section forming anelongate channel 3. In a horizontal orientation the rail has a substantially planarfront panel 4 having top andbottom edges bottom panels inner channel 3. When horizontally anchored to awall 2, thebottom panel 8 forms an elongate ledge having arear edge 9. The rail is anchored and spaced a controlled distance apart from the wall to form a gap G so that therear edge 9 of the ledge is substantially parallel to the plane of thewall 2. - The rail has a number of regularly spaced
holes 10 extending through from the front surface of thefront panel 4 to thechannel 3. Each hole is sized to accommodate ascrew 11 inserted for the purpose of anchoring therail 1 to thewall 2 as shown more clearly inFIG. 4 . Eachhole 10 is countersunk into the front panel so that the fastening screws are flush with the outer surface of the rail after installation. - To maximize the load carrying capability of the screws at the rail hole locations, particularly when installing the screws into dry wall, commercially available expansion anchors 15 may be employed as shown in
FIG. 4 . Therail 1 is anchored spaced a controlled amount apart from the wall to form a gap G, usingspacers 16 whose thickness T can determine the size of the gap. The gap can be about ⅛ of an inch. Eachspacer 16 can be formed using two concentrically alignedadjacent washers Washer 18 has a centerhole 20 having an internal diameter that is slightly larger than the widenedhead 14 of the expansion anchor so that it can be accommodated without interference.Washer 19 has a centerhole having an internal diameter slightly larger than thescrew 11 shaft but smaller than the diameter of theexpansion anchor head 14. This arrangement prevents the expansion anchor from backing out of the wall when the screw is fastened to the wall and also provides a solid mounting of the rail gapped ⅛″ away from the wall. The twowashers - The regularly spaced screw holes 10 incorporated in
rail 1 also serve as a template for locating the attachment points on the wall. Attachment points 25 on the wall are therefore not governed by stud locations on the wall but rather by the predetermined hole spacing on the rails. In this way, installation of the system is simplified so that relatively unskilled persons can accomplish it quickly and easily. Full load capability is achieved by the use of the wall expansion anchors 15. The incorporation of the holes in the rail eliminates the need to explore the wall for stud locations and also precludes the need to for the installers to make metal drillings into the rail. - Referring now to
FIGS. 5 and 6 show respectively the front and side views ofcable assembly 28. It is comprised of a length ofmulti-strand cable 29,retainer clip 30, andcable compression ferrules 31 installed on both ends of the cable. Ahole 32 is incorporated on the centerline ofretainer clip 30 allowing thecable 29 to pass through. The compression ferrules 31 at both ends serve to keep the multi-strand cable from unraveling at its end portions, to retain the cable so that it cannot be extracted fromretainer clip 30, and to carry the full load imparted by pictures connected to the cable. Theclip 30 is formed by abacking portion 35 having a substantiallyplanar back surface 36 to bear flatly against the wall surface when the clip is properly engaging the rail. Aprong portion 37 extends forwardly from an upper portion of the backing at an angle A to form a substantially L-shaped structure. The clip also has a substantially similarly angled L-shapedspring arm structure 40 extending forwardly from alower portion 38 of thebacking 35 and oriented to resiliently nest into the backing and backing prong. This provides a pair of surfaces to bear against the opposing surfaces formed by thewall 2 andedge 9 of the ledge thereby increasing friction between the clip and rail to help prevent the clip from being inadvertently moving. The spring arm also has a prong forwardly projecting from an upper portion of the arm. Both the backing prong and spring arm prongs slidingly contact each other to allow compression of the clip and provide added strength to the clip. - The transition from backing to prong is made by a gradual
rounded bend 41 so that rotational movement of the clip can be made smoothly. - The retainer clip is typically made of a corrosion resistant spring type metal alloy such as stainless steel. The cable is typically made of corrosion resistant stainless steel and although small in diameter has a load rating sufficiently high to be able to carry several heavy pictures with a sizeable safety factor included.

FIG. 7 shows a front view of an integral cable clamp andpicture hook assembly 52 andFIG. 8 shows a sectional side view of the assembly. The assembly is comprised of abody member 53 having a substantially U-shaped cross-section. In an orientation to engage a vertically hangingcable 29 and to have a frontwardly projectingpicture hook 54, the body member has front and back clampingplates upper apex 57 to allow thecable 29 to pass between the inner clamping surfaces 60, 61 formed by the plates. The body member incorporates twoconcentric drillings screw 64 is pressed into thedrilling 63 in the front plate and inserts through the other drilling in the back plate to engage awing nut 65. The screw and wing nut form an adjustable fastener so that tightening fastener creates a powerful clamping action on the body plates to reduce the distance between the plates and thereby clamp onto a medial portion of the cable placed in the space between the plates. In this way, the cable is not kinked by the clamping plates. - The
body section 53 can be inexpensively formed from a single cut sheet of metal that has been folded twice, first to create theclamping plates hook portion 54. The apex 57 of the body member has acutout 70 extending medially from onelateral edge 71 and terminating at anendstop 72 just beyond thecenterline 75 of the body. The drillings in the body and the cutout are configured in a manner so that when acable 29 is inserted into the body it is guided at two points that align the cable to pass precisely through the centerline of the body. This is important to achieve symmetrical loading and avoid any cocking of the clamp andhook assembly 52 when a picture is hung on the hook. In other words, theendstop 72 and thelateral edge 76 of the part of thethumb screw 64 bridging the space between the plates are located about ½ the width of the cable so that the center of the cable passes through the centerline. Insertion of the clamp into the cable and removal from the cable is directly from the side. This is very important in achieving speedy engagement and disengagement of the clamp andhook assembly 52 with thecable 29. -
FIGS. 9, 10 and 11 show the stepwise connection process of thecable assembly 28retainer clip 11 torail 1.FIG. 9 shows the initial insertion and engagement of theretainer clip 30 into the rail. The retainer clip at this point is in an uncompressed state. Next, inFIG. 10 it is rotated clockwise and partially compressed between therail 1 and thewall 2 by the act of rotation. Finally, inFIG. 11 , continuing the clockwise movement of the retainer clip, it is fully compressed between the rail and the wall with thecable 29 extending downward next to the wall. At this point the cable assembly is securely connected to the rail with both retainer clip prongs engaging the lower ledge of the rail and fully capable of carrying the load imparted by pictures connected to the cable. -
FIG. 12 shows an isometric view of the picture hanging system deployed on a wall section. Therail 1 is shown properly gapped G away from thewall 2, theretainer clip 30 of thecable assembly 28 engages the rail and the cable clamp andhook assembly 52 is connected tocable 29. The cable clamp and hook assembly is now ready to receive a picture. If initially the hook is not in the exact desired position it can be shifted horizontally by moving the retainer clip to a new location on the rail. This does not require a complete disengagement of the cable assembly from the rail but rather only a partial counterclockwise rotation of the retainer clip, slidement along the rail to its new location, followed by a clockwise rotation of the clip into its engaged position. Final vertical positioning of the hook is then accomplished if necessary by loosening the wing nut, sliding the cable clamp andhook assembly 52 vertically on thecable 29 to the desired location, followed by tightening of the wing nut. The picture is hung on the hook and the installation is complete. - The
rail 1 as installed is fully functional. However because of the aesthetic requirements of most gallery settings it is desirable but not essential to cover the rail and associated visible fasteners with a moulding. A typicalcosmetic moulding 76 comprised of a wood, plastic or metal channel section that fits closely over the outer surfaces of therail 1 is shown inFIG. 12 . Other moulding shapes are also possible including angle sections, flat strips or contoured shapes. As necessary the mouldings can be attached to the rail using double sided adhesive tapes or adhesive backed Velcro strips, press fit channel wood or plastic etc. The mouldings can be painted if deemed necessary to blend in with the wall. Typically the mouldings are standard commercially available parts. -
FIG. 13 shows a variety of ways that pictures can be hung on a wall and the versatility of the picture hanging system. On the left side ofFIG. 13 a picture 81 is hung in its intended location. Excess cable length is coiled up 82 upon itself before the picture is hung so that the cable is hidden behind the picture.Picture 83 is shown hanging below and slightly to the right ofpicture 81. The cable that supportspicture 83 is routed behindpicture 81. In the center ofFIG. 13 picture 85 is shown hanging directly beneathpicture 84, both suspended from asingle cable assembly 28 that employs two clamp andhook assemblies 52. If desiredpicture 84 can be removed from the wall without disturbingpicture 85 by simply loosening and directly removing the associated clamp and hook assembly from the cable. A large andheavy picture 86 is shown on the right side ofFIG. 13 . It is supported by two cable assemblies and two clamp and hook assemblies. This suspension method doubles the load carrying capacity of the system and also prevents a picture from moving laterally on the wall due to some external disturbance. - While the preferred embodiment of the invention has been described, modifications can be made and other embodiments may be devised without departing from the spirit of the invention and the scope of the appended claims.
