The present invention relates generally to hanging of picture frames, and more particularly to a picture frame having an automatically retracting cord reel and cooperating cord locking mechanism to allow adjustment of a cord length for hanging of the frame at different heights without vertically relocating a support from which the picture is hung.
It is known in the art to use a self-retracting cord reel mounted to the rear of a picture frame to span a cord across the rear of the picture frame for hanging thereof from a suitable hook, where the amount of cord deployed from the reel can be changed in order to change the height at which the frame is suspended from the hook, thus allowing easy adjustment of the picture height without vertical relocation of the hook.
Examples of such arrangements are shown in U.S. Pat. Nos. 6,965,10 and 8,620,11. However, in each of these prior art picture frame and hanger combinations, the reel forms a bulky installation on the rear of the frame, preventing the frame from lying closely against the wall or other upright surface behind the picture frame.
Accordingly, there remains room for improvement in picture frame and cord-reel picture hanger combinations.
According to a first aspect of the invention there is provided a picture frame and hanger combination comprising:
a reel having a cord secured thereto and being rotatable in opposing directions acting to wind and unwind said cord around said reel;
a locking mechanism operable to lock the cord in any of a number of partially unwound states each corresponding to a different length of said cord being deployed from around said reel; and
a frame bordering a picture opening in which a picture is mountable in a position facing outward from the picture opening to a front side of the frame, the frame having a hollow cavity positioned and sized to accommodate the reel in a position that is concealed from the front side of the frame behind a front face thereof and is located at least partially between said front face of the frame and an opposing rear face thereof.
Preferably the reel is biased to rotate in the direction acting to wind said cord around said reel, and the locking mechanism is biased into a locking state. In order words, preferably the reel is an automatically retracting reel configured to bias the cord toward a fully wound condition on the reel, and the locking mechanism is an automatically locking mechanism configured to bias the cord into a locked condition fixing the length of cord deployed from the reel.
Preferably the reel is located entirely between said front and rear faces of the frame.
Preferably the hollow cavity is a recessed cavity recessed into the frame from an exterior thereof.
Preferably the hollow cavity is a recessed cavity recessed into the frame from the rear face thereof.
There may be provided a cover mounted over the recessed cavity. When such a cover is included, preferably the recessed cavity comprises a stepped border creating a ledge for seating of the cover in a position flush with or recessed from the rear face of the frame. A cord passage opening, for passage of the cord from the hollow cavity through said cord passage opening, may be provided on the frame, for example in the cover.
Preferably a hollow space in the frame is positioned and sized to receive at least a portion of the locking mechanism between the front and rear faces thereof.
Preferably the hollow space for receiving the locking mechanism is part of the hollow cavity for accommodating the reel. In other words, preferably the hollow cavity is sized to accommodate both the reel and the locking mechanism at least partially between the front and rear faces of the frame.
The frame may have a lock actuator opening arranged for access to an actuator of the locking mechanism from outside the hollow space. This lock actuator opening may be provided in the cavity cover in embodiments including such a cover.
Preferably the actuator of the locking mechanism is a release actuator operable to release an automatic locking action of the locking mechanism on the cord.
Preferably the release actuator is a push button release actuator.
Preferably there are provided multiple cord attachment points on the frame at different sides of the picture opening bordered thereby for selective connection of a free end of the cord to any of said attachment points.
Preferably there is provided a stop member attached to the cord at a free end thereof, the stop member being impassable through the cord passage opening.
Preferably the reel mechanism is located on a first side of the picture opening having a first one of the attachment points, and a cord guide is provided on the frame on a second side of the picture opening for routing the cord from the reel to said a second one of the attachment, which is also located on the second side of the picture opening.
Preferably there is provided a connector attached to the free end of the cord for engagement of the connector to any of said attachment points.
Preferably the connector is a clip.
Preferably the connector is passable through an opening of the cord guide.
In one embodiment, the reel and the locking mechanism are mounted within a common housing installed within the hollow cavity of the frame.
According to a second aspect of the invention there is provided a method of producing a picture frame and hanger combination comprising:
providing a hollow cavity between opposing front and rear faces of a frame that borders a picture opening in which a picture is mountable in a position facing outward from the picture opening to a front side of the frame; and
mounting a reel at least partially within the hollow cavity of the frame, the reel having a cord secured thereto, being rotatable in opposing directions acting to wind and unwind said cord around said reel, and being provided in combination with a locking mechanism operable to lock the cord in any of a number of partially unwound states each corresponding to a different length of said cord being deployed from around said reel.
According to a third aspect of the invention there is provided a picture hanging device comprising:
a housing comprising first and second shell pieces engaged together to enclose an interior space;
a self-retracting reel rotatably mounted within the interior space of the housing; and
a locking mechanism mounted within the interior space of the housing and operable to provide an automatic locking action to lock the cord in any of a number of partially unwound states each corresponding to a different length of said cord being deployed from around said reel, the locking mechanism comprising a push button actuator extending through an opening of housing for actuation of said actuator from outside the housing to release the automatic locking action on the cord.
In the accompanying drawings, which illustrate exemplary embodiments of the present invention:

With reference to
The smaller circular portion 14 of the hollow cavity 10 features a cord lock mechanism 20 through which the cord passes from the drum to the free end of the cord. The cord lock may also be of a known conventional type, with a push button plunger 22 slidable back and forth in an axial direction in a blind hole of main housing 24. The plunger and the housing have parallel through-bores 22a, 24a extending in a direction perpendicular to the sliding direction of the plunger. A compression spring 26 is disposed between the closed end of the housing's blind hole and the inner end of the plunger inside the blind hole. In its normal extended state, the compression spring 26 forces the plunger away from the closed end of the blind hole, attempting to force the transverse bore of the plunger fully past the transverse bore of the housing. When the spring 26 is depressed by manual pressing of the plunger, it acts to move the transverse bores into an at least partially aligned condition where the bores are open to one another. The cord from the reel passes through the lock mechanism via the two transverse bores.
As schematically shown in
With reference to
The cover features a cord-accommodating hole 36 therein near the narrower upper end of the cover to allow the cord to pass through the cover from the cord lock 20 inside the hollow cavity to the exterior of the picture frame. A larger lock actuator hole 37 situated a short distance below the cord-accommodating hole 36 provides an opening through which one's finger can depress the plunger 22 of the cord lock 20, or through which the plunger 22 extends to provide access thereto outside the picture frame at the rear side thereof. A first eyehook 38 is fastened to the rear face 4a of the upper cross-wise frame piece 4 that projects horizontally from the upper end of the upright frame piece 1 near the hollow cavity formed therein. This first eyehook 38 forms a guide near the end of the cross-wise frame piece 4 lying adjacent the upright frame piece 1 with the hollow cavity. The cord 28 passes through the opening of this guiding eyehook 38, and a clip 40 fixed to the free end of the cord 28 is releasably connected to the eye of a second eyehook 42 disposed at an opposite end of the same cross-wise frame piece 4. The two eyehooks are situated at matching positions across the width of the cross-wise frame piece 4 to lie at the same height when the length of this piece 4 is oriented horizontally. The span of the cord between the two eye-hooks forms a hanger by which the picture frame can be suspended from a hook or other suitable support on a wall or other upright surface.
A third eyehook 44 is fastened to the reel-quipped upright frame piece 1 adjacent the lower end thereof opposite the hollow cavity. This eyehook 44 is situated at a position matching that of the cord-accommodating hole 36 in the cover 34 across the width dimension of the upright frame piece 1. The opening in the guiding eyehook 38 is large enough to accommodate passage of the clip 40 therethrough, whereby the free end of the cord 28 can be decoupled from the second eyehook 40, drawn back through the guiding first eyehook 38, and then extended along the first frame piece 1 to attach to the third eyehook 44. This way, the cord 28 can be reoriented to lie along the first frame piece 1 in which the hollow cavity is formed instead of the shorter adjacent frame piece 4. The cord 28 can then be used to hang the picture frame from the first frame piece 1 instead of the other frame piece 4, allowing the elongated rectangular picture frame to be hung in either a length-upright portrait orientation or a length-horizontal landscape orientation according to the picture that is to be displayed within the frame.
While the clip is small enough to fit through the guiding eyehook 38, it is too large to fit through the cord-accommodating opening 36 in the cover installed over the hollow cavity of the frame. This way, the inability of the clip to fit through the cord-accommodating opening 36 prevents the free end of the cord from being retracted into the hollow cavity when the lock-release plunger of the cord lock is depressed.
The tension that acts against the extension of the cord from the reel is sufficient to suspend the weight of the frame, glass, picture and backing without extending the cord, for example providing 10-lbs of tension, with the spring strength and frictional engagement of the cord at the locking mechanism being strong enough to hold the cord against the reel's cord-retracting action. To change the height at which the picture is hung, a user depresses the lock-release plunger of the cord lock, and either pulls more of the cord from the reel in order to increase the freed length of cord to obtain a lower picture height when hung, or allows the reel to automatically retract more cord in order to tension the cord to a reduced length in order to increase the picture height when hung. After the hanging-cord is adjusted to a desired length, release of the lock plunger automatically locks to the cord to this effective picture-hanging length. With the recessed condition of the cord lock entirely within the frame between the front and rear faces thereof, this adjustability is provided in a relatively thin configuration comparable to that of a conventional picture frame lacking a length adjustable hanging cord.
The picture frame may be factory equipped with the hollow cavity and corresponding reel and lock combination, or existing picture frames may be retrofitted to add a reel and lock combination by forming a suitable recessed cavity into which a separately acquired reel and lock combination can be mounted in one of the frame members. Even embodiments where the reel and lock are only partially recessed into the frame would still provide space-efficient advantage over the prior art configurations with entirely external cord retracting and locking mechanisms. Although the illustrated embodiment features a rear-access cavity for optimal concealment of the cavity when the picture frame is hung against a wall or other upright surface, other embodiments may employ other configurations, for example a cavity recessed into the frame from an outer peripheral edge thereof, with a suitable cord-accommodating hole through to the rear of the frame. Other rear-access embodiments may forgo a cavity cover if the cavity is sufficiently hidden from sight when the frame is hung and the reel and lock are secured to the frame.
Although the forgoing embodiment employs separate reel and lock mechanisms, other embodiments may combine these mechanisms into a single unit, for example having a singular unitary housing of molded plastic. Where separate mechanisms are used, they may be mounted in separate recessed cavities, provided that suitable passage for the cord from one cavity to the other is provided. The picture frame may be produced from any of a number of different materials, including but not limited to solid wood or medium density fibreboard (MDF).
With reference to
In the same circular area as the fastener-receiving boss 78, the top wall 72 of the top shell piece 52 features a plunger-receiving opening 80 of diameter that slightly exceeds the cylindrical portion 68 of the plunger 64, but is less than the diameter of the plunger's flange 66, and also features a cord-receiving opening 82 of greater diameter than the cord 28. A retaining wall 84 depends perpendicularly from the top wall 72 around the two openings 80, 82 therein, and curves concentrically and conformingly around the plunger-receiving opening 82 at a at a radial distance therefrom that slightly exceeds the radial extent by which the plunger's flange 66 projects from the cylindrical portion of the plunger. That is, a diameter between opposing arcuate sections of the retaining wall 84 slightly exceeds the diameter of the flanged end of the plunger 64.
With reference to
Inside the core of the reel drum 58, a spiral flat spring 90 has one end 90a fitted within the diametrical slot 88 that separates the two halves of the split-cylinder boss or post 76, and the other end connected to the cord 28 where the cord enters the interior space of the drum core through a suitable opening therein. In the assembled housing, the walls of the reel drum at opposite ends of its hollow cylindrical core feature central holes 58a, one of which accommodates insertion of the split-cylindrical post 76 into the core of the drum during assembly of the housing. The drum thus rotates about the axis of the split-cylindrical post 76 inside the respective circular area of the housing's interior space enclosed between the two shell covers 52, 53.
In a known manner, the action of the spiral flat spring cooperates with the cord and drum to define a self-winding reel, where pulling of the free end of the cord from the reel acts to tighten or wind the spiral spring as the drum rotates about its central axis in this direction that unwinds the cord from same. The built up tension in the spring, when released, thus acts to automatically pull the cord in the opposing direction, thus turning the drum in this second direction so as to rewind the cord back onto the drum. The spring biased plunger 64 normally holds the cord in place against the cord-winding tension of the spiral flat spring. However, when a user depresses the exposed cylindrical end of the plunger outside the housing against the bias of the compression spring 62, the cord is released from its clamped position against the top shell of the housing, whereupon the action of the spiral flat spring automatically winds the cord back onto the drum.
A threaded fastener is engaged through central bores of the fastener-receiving bosses of the two shell pieces of the housing, for example via a counter-bored end 92 of the through-bore in the bottom piece's boss 60 that extends through the bottom wall of the bottom piece 53. Such fastener thus secures the two shell covers 52, 53 together in the assembled state. Fastening ears 94 project from the outer periphery of the housing, for example at opposing ends of the top shell piece, and feature respective through-bores 96 through which screws may be driven into the bottom of the picture frame recesses in order to secure the assembled reel and lock unit in place in the recess of the picture frame.

End consumers or frame manufacturers or sellers may purchase a combined reel and lock unit prefabricated by another manufacturer, and then install the purchased unit in any picture frame by modifying the frame to include a suitably shaped recess to accommodate the housing of the reel and lock unit, for example using readily available professional or consumer grade tools. For example, and end consumer may trace the shape of the housing onto the rear face of the frame using either a suitable template or the housing itself, drill a blind hole into the frame, and then from the blind hole, use a hand router to hollow out the traced area for subsequent mounting of the housing into the resulting recessed cavity of the frame. A frame manufacturer or customizer may follow a similar process, or use larger scale machining equipment to similarly create the housing-accommodating cavity in the frame. It will be appreciated that the shape of the recess does not necessarily need to conform to that of the housing, and that the housing may be provided with shapes other than the figure-eight shape shown and described herein.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
