This application relates generally to wall-mounted hooks, and more particularly to wall-mounted hook rails and related mount anchor components.
Numerous products exist for installing a hook or hanging device in a wall, such as for hanging a picture frame, a mirror, or the like. Conventional nails and screws are not always convenient solutions and may not provide sufficient support strength in the wall, particularly in the case of drywall, or other friable wallboards, which are relatively weak.
Anchors incorporating curved saber tooth shaped retainers are known from U.S. Pat. Nos. 8,974,166 and 8,414,239. However, such anchors are still difficult for the typical homeowner to install and use properly because a hammer is generally needed to complete the anchor installation. These anchors also generally have a large wall penetration that tends to crumble and weaken the surrounding wall media adjacent the penetration and leave a large hole that is not easily repaired. It is also impractical to reposition these types of anchors after initial insertion in locations proximate the original hole for the purpose of making minor adjustments.
It would be desirable to provide a hook rail that utilizes an anchor device and related installation method that facilitates ease of installation, but at the same time results in a mounted hook rail with a high support strength and less damage to the wallboard, leaving relatively small holes upon removal and therefore also permitting minor position adjustments if needed.
The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description and drawings, and from the claims.
In one aspect, a hook rail assembly for hanging objects on a wall includes an elongated rail member having front, back, top, bottom, left and right sides, the back side including one or more portions that define a wall mount plane of the rail member. First and second anchor components are connected to the back side of the rail member, each of the first and second anchor components including a base having front, back, top, bottom, left and right sides, at least one wall penetrating retainer extending from the base and having a wall penetrating extent that that protrudes rearwardly of a wall mount plane of the rail member and has a downwardly curved configuration. The front side of the rail member includes multiple protruding hook members. Each of the first and second anchor components is formed separate from the rail member and attached thereto.
In another aspect, a hook rail assembly for hanging objects on a wall includes an elongated rail member for abutting the wall, at least one anchor component connected to a back side of the rail member and at least one hook member positioned at a front side of the rail member. The anchor component includes a base and at least one wall penetrating retainer, the wall penetrating retainer having a wall penetrating extent that that protrudes rearwardly of the rail member and has a curved configuration. The wall penetrating extent is arcuate and has a radius of curvature with a center point proximate a bottom side of the rail member.
In another aspect, a hook rail assembly for hanging objects on a wall includes an elongated rail member for abutting the wall. A first anchor component connects to a back side of the rail member, the anchor component including a base and at least one wall penetrating retainer, the wall penetrating retainer having a wall penetrating extent that that protrudes rearwardly of the rail member and has a curved configuration. A first hook member is positioned on a front side of the rail member. The first anchor components is formed separate from the rail member and attached thereto and the first hook member is formed separate from the rail member and attached thereto. A common fastener engages the first anchor component and the first hook member to secure both the first anchor component and the first hook member to the rail member. Additional anchor components may be similarly mounted to the rail member.
In a further aspect, a hook rail assembly for hanging objects on a wall includes an elongated rail member for abutting the wall. A plurality of hook members are positioned on a front side of the rail member. An anchor component is connected to a back side of the rail member, the anchor component including a base and at least one wall penetrating retainer, the wall penetrating retainer having a wall penetrating extent that that protrudes rearwardly of the rail member and has a curved configuration. The back side of the rail member is recessed and includes a seating arrangement comprising spaced apart first and second ribs with respective distal edges. The distal edge of the first rib defines a first recessed slot and the distal edge of the second rib defines a second recessed slot, the first recessed slot aligned with the second recessed slot, the first recessed slot and the second recessed slot receive and support a base of the anchor component. Additional anchor components may be similarly mounted to the rail member.
In the drawings and description of the various embodiments below, the term wallboard is generally used to refer to the most common wallboard such as drywall, but it is recognized that the anchor components could be suitable for any other friable wallboard material, such as dense corks or foams or other materials that can crumble. Accordingly, the term wallboard as used herein is intended to broadly encompass, for example, both typical drywall (aka plasterboard and gypsum board) and such other friable wallboard materials. However, it is also recognized that in some applications the anchor assemblies may be installed into harder wall materials by utilizing pre-drilled holes.

The front side of the rail member 602 includes multiple protruding hook members 622. Here the hook members connect substantially along the height of the rail member and protrude forward, but other variations are possible. The hook members 622 are formed separately from and connected to the rail member, but hook members formed monolithic with the rail member are also contemplated.
A plurality of anchor components (here just two) 628 are connected at the back side of the rail member, within the recess 620. Each anchor component 628 may be of metal plate construction and includes a base plate 630 having front, back, top, bottom, left and right sides, and at least one wall penetrating retainer 632 extending rearwardly from the base plate and having a downwardly curved configuration. Each anchor component is formed separate from the rail member 602 and is attached thereto at the back side utilizing cooperating structural features on each of the anchor component and the rail member. Each wall penetrating retainer includes a wall penetrating extent 632A that that protrudes rearwardly of a wall mount plane 606A of the rail member and has a downwardly curved configuration. In particular, the wall penetrating extent may be arcuate in configuration, where a center 632B of the radius of curvature R632 of the wall penetrating extents 632A is below and rearward of the bottom of the base plate 630 (per
As best seen in
As will be described in further detail below, the wall penetrating retainer 632 of the anchor components extends from the base and has an initial forward progression. To accommodate this configuration, a distal edge 658 of the rib 654 is recessed per slot 660 relative to the distal edge of the rib 642 in slot 650. On the other hand, the distal edge 662 of the rib 656 is not recessed relative to the distal edge of the rib 644 in slot 652. Thus, the anchor component 628 can only be seated in the seating arrangement with the wall penetrating retainer 632 positioned by the rib 654. This configuration helps assure that the anchor components are always installed to the rail member in a specific, desired orientation.
In terms of fixing the anchor components to the rail member, each anchor component includes a mount opening 670 in its base 630, and each seating arrangement 640 includes a mount hole 672 that is aligned with the mount opening 670. A screw or other fastener 674 passes through the mount opening 670 and into the mount hole 672 to secure the anchor component to the rail member, with a head of the screw engaged with the rear side of the anchor component base 630.

Notably, the anchor components 628 utilized in connection with the hook rail assembly 600 are configured to enable straightforward mounting of the hook rail assembly to a wall. In particular, and referring to
A wall penetrating retainer 632 extends from the base and has a rearwardly protruding wall penetrating extent 632A with a primarily downwardly curved configuration as will be described in greater detail below. In the embodiment of anchor component 628, the wall penetrating retainer 632 is formed monolithic with the plate material of the base plate (e.g., utilizing a progressive stamping operation). In the illustrated anchor component 628, the retainer 632 is formed by an appropriately bent portion of metal plate and departs from a side edge of the base plate.
In one implementation, the metal plate may be cold rolled alloy sheet steel (e.g., AISI 4130 per ASTM A506/507) with a thickness of between about 0.040 inches and about 0.052 inches (e.g., no more than 0.052 inches), and the resulting anchor component may have a tensile yield strength of no less than 160 KSI and a minimum elongation of 3%. By making use of this ultra-high strength steel a thinner plate material can be utilized to achieve a desired load rating, enabling reduced cross-sectional size of the wall penetrating retainers in order to reduce required insertion force and minimize wall damage. The elongation characteristic assures adequate ductility after hardening.

In order to facilitate installation of a hook rail assembly, the wall penetrating retainers of the anchor components can also be configured with other advantageous features.
For example, to facilitate manual wallboard penetration and passage without tools, utilizing thumb force only (e.g., applied at the thumb capture zones), the wallboard penetrating retainers 28 may be formed with a relatively smooth external surface finish (e.g., achieved by polishing, painting or plating). In this regard, the surface of the wallboard penetrating retainers 28 can be manufactured with or modified to a maximum average surface roughness of about 20 μinch (e.g., in some cases a maximum average surface roughness of about 15 μinch). In one implementation, just the wallboard penetrating extent of each wallboard penetrating retainers is worked, processed or otherwise formed to achieve this desired low surface roughness feature in order to reduce manufacturing cost. The latter implementation would reduce install force but maintain friction on the rougher portions of the penetrating retainer to resist removal forces. The retainers may have a polished surface finish and/or a plated surface finish and/or a painted finish and/or a lubricant (e.g., Teflon) incorporated into the surface finish.

In this regard, proper sizing of the wallboard penetrating retainer(s) can also be used to achieve more user friendly performance of an anchor component. In particular, per
In one example, low insertion forces for the retainer(s) of a given hook rail assembly may be achieved where the retainers have pointed distal ends as described above and a generally uniform cross-section along the remainder of the wall penetrating extent of the retainer, where an area of the cross-section is no more than about 2.5 mm2. In one example, in the case retainers of rectangular cross-section, the main segment of the wall penetrating extent of each retainer may be on the order of 0.042 inches by 0.068 inches (e.g., 0.042 inches thick and 0.068 inches wide), resulting in a cross-sectional area of about 0.00286 in2 (about 1.845 mm2). In another example, the main segment of the wall penetrating extent may have a rectangular cross-section on the order of 0.050 inches by 0.075 inches (e.g., 0.050 inches thick and 0.075 inches wide), resulting in a cross-sectional area of about 0.00375 in2 (about 2.419 mm2). It may be advantageous (e.g., for the purpose of ease of install and/or for the purpose of limiting wall damage) to assure that the total retainer cross-sectional area (e.g., the combined cross-sectional area of the two retainers of hook rail assembly 600) is no more than about 5 mm2 (about 0.008 square inches, or in some cases no more than about 6 mm2), where the cross-section of each wall penetrating extent of the retainer is taken perpendicularly to a lengthwise axis 292 (

A plurality of anchor components (here just two) 128 are connected at the back side of the rail member, within the recess 120. Each anchor component 128 may be of metal plate construction and includes a base plate 130 having front, back, top, bottom, left and right sides, and at least one wall penetrating retainer 132 extending rearwardly from the base plate and having a downwardly curved configuration similar to that of the embodiments described above. Each anchor component is formed separate from the rail member 102 and is attached thereto at the back side utilizing cooperating structural features on each of the anchor component and the rail member. The anchor components 128 may be of similar configuration to anchor components 628 described above.
The back side of the rail member includes an anchor seating arrangement 140 for each of the anchor components. The anchor seating arrangement retains the anchor to the rail member. In the illustrated embodiment, each anchor seating arrangement 140 includes a set of vertically and horizontally spaced apart slots 142 into which opposite corners of the anchor component 128 are positioned when the anchor component is in a seated position (e.g., the position shown in
In order to hold each anchor component in its seated position, each anchor seating arrangement 140 also includes at least one retention feature 152 that engages with the anchor component to inhibit rotation of the anchor component 128 from the seated position back to the initial position. In the illustrated embodiment the retention feature 152 is formed by a short finger that extends from part of the rim portion 118 of the rail member and includes a curved or ramped surface portion 154 that interacts with the anchor retainer 132. In particular, the anchor retainer 132 slides along the surface portion 154 during the rotation of the anchor component into the seated position. When the retainer 132 clears the finger, an edge 156 of the finger engages with an edge of the retainer 132 to hold the retainer in place. The finger 152 may flex slightly during this process. Likewise, at least some relative flex between each anchor component and its retention feature 152 may be provided to enable the anchor component to be rotated from the seated position to the initial position.

The rail assembly includes a plurality of hook members 222. The hook members 222 are initially formed separately from and the attached to the rail member 202. For this purpose the rail member 202 includes a plurality of hook receiving openings 260 through which a connecting end 270 of a hook member is positioned. In this regard, in the illustrated embodiment the through openings 260 and the hook members 222 are respectively sized and shaped to enable the hook member to be connected into the through opening by inserting the connecting end 270 through the opening 260 at the front side of the rail and sliding the slot 262A to the top edge of the opening 260. The lower flange 264 then deflects and snaps over the bottom edge of the opening 260. Once installed, the connecting end 270 of each hook member includes spaced apart upper and lower retention flanges 262 and 264 that extend beyond respective peripheral edges of the rail member through opening 260 (e.g., see
Where the hook members are removable from the rail member, the hook members can be packed as separate pieces (e.g., laying down sideways in a package that also includes the rail member) in order to reduce space taken up by the package and thus reduce shipping costs.
Another embodiment of a hook rail assembly 300 is shown in
The seating arrangement 340 also includes a rearwardly projecting feature 382 (here a pin-shaped member, though other shaped projections could be used) that acts as the anchor retention feature. Each base plate includes a further opening 384 that aligns with the pin member 382 when the anchor component is in the initial position so as to enable the corner regions of the anchor component base plate to enter the slots 342. When the anchor component 328 is rotated into its seated position, the surface of the base plate slides over the pin (e.g., the upper end of the pin or other feature may be ramped or tapered for this purpose) until the edge of the base plate clears the pin 382 and drops laterally alongside the upper portion of the pin 382. The interaction of the pin 382 and base plate edge then inhibits rotation of the anchor component out of its seated position under normal operating conditions. Notably, each anchor component includes a set of spaced apart openings 384 so that the identical anchor component configuration can be used for either a seating arrangement with counter-clockwise anchor component seating or clockwise anchor component seating.
The hook members 322 are initially formed separately and then attached to the rail member 302. In this embodiment the through openings 360 of the rail member are surrounded by rib features 390 projecting rearwardly at the back side of the rail member that strengthen the rail member in the vicinity of hook connection. The hook members 322 include a connecting end 370 and a hook end 372, where the connecting end is adapted for linear insertion through the rail member opening 360. In this regarding, the connecting end 370 includes upper and lower retention fingers 374 and 376 that flex inward as they interact with the edges of the opening 360 when the connecting end is passed from the front side of the rail member through the opening 360. As retention tabs or flanges 378 and 379 on the fingers clear the back edge of the opening, the fingers flex back outward so that the tabs 378, 379 will extend beyond the perimeter of the opening to retain the hooks on the rail member (e.g., see
It is to be clearly understood that the above description is intended by way of illustration and example only, is not intended to be taken by way of limitation, and that other changes and modifications are possible. For example, while the illustrated hook rail assemblies contemplate multiple hooks and multiple anchors connected to a rail member, it is recognized that a single anchor could be connected at the back side of a single hook (e.g., a fashion hook) in a manner similar to that described above to achieve a hook and anchor assembly. Moreover, other variations of attachment of the anchor component(s) to the rail member are possible, such as overmolding or heat stacking or any other suitable manner.
