This invention relates to the field of cabinetry and more particularly to a device and method for the connection of panels.
Cabinetry and furniture are commonly constructed using sheet goods, such as plywood. The sheet goods are used to form boxes, typically with edges joined at ninety-degree angles. Sheet goods are much larger than their thickness, often sold in 96″×48″ panels, with thickness of ⅜″, ½″, ⅝″, or ¾″, in English sizes, and similar dimensions in Metric sizes.
Joining sheet goods at a ninety-degree angle causes the two sheets to form a T or L shape. Thus, the narrow thickness, such as ½″, is all the thickness presented to make a joint.
While complex ways, such as dovetail joints, exist to address this issue, dovetail joints are complex to cut. Mechanical connectors, such as screws, provide insufficient strength for many applications.
What is needed is a device and method of joining sheet goods that is simple to install but creates strong joints.
The disclosed device is a connector that slides into a T-slot in a first panel, and a stepped slot in a second panel. The connector includes a perpendicular head to lock into the T-slot, and an upward protrusion to slide into the stepped slot. A tab locks into a depression with the stepped slot, locking the connector in place.
In an alternative embodiment, the slot in the second panel is not stepped, but has non-stepped sides. This allows the connector to be inserted through the top face of the panel, rather than the edge.
Thus, installation into a first panel is via a routed depression in an edge, into which the connector slides.
Installation into the second panel is by sliding into a slot. The item is slid into the slot either at an edge, or through a hole formed in the face of the panel, allowing installation of the connector through the face, then slid into position.
The above device can be shaped in multiple ways, but with common features of being readily removable and easy to install.
The connector is preferably constructed with a downwardly protruding locking tab. Alternatively, the tab protrudes outward, allowing the connector to lock into a recess when the connector is inserted through the face of the panel, rather than the edge.
Note that the listed dimensions within are for reference only based on a typical connector size. The connector can be scaled up or down, as well as proportions changed, without affecting the function.
To install the first embodiment, first the two panels are prepared.
To prepare the first panel:
To prepare the second panel:
Accurate cutting is required to ensure a proper fit. But dimensions may be changed slightly to affect the tightness of a given fit.
Steps for Installation:
To remove the device, reverse the above steps, but prior to removing the connector from the first panel:
After installation, when the panels are locked into each other, the faces of the panels should align without adjustment.
As a further alternative, there is the option of flipped versions of each of the above embodiments.
The flipped versions are installed on the opposite side of the first panel. In other words, the above embodiments are installed on the inside of a cabinet, the flipped versions are installed on the outside.
The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.
Referring to
The panel connector 1 bridges the first panel 100 and the second panel 102.
The body 10 of panel connector 1, with projecting rib 12, fits within the V-shaped stepped slot 110 of the first panel 100. Specifically, the narrower body 10 sits within the wide slot section 112, the projecting rib 12 sits within the narrow slot section 114.
The locking tab 30 interfaces with the tab depression 116, preventing the panel connector 1 from sliding out of the first panel 100. During insertion, the locking tab 30 can deform at the living hinge 34, the locking tab 30 moving into the compression space 32. The insertion ramp 38 guides the locking tab 30 up and over, latching into the tab depression 116.
The head 14 fits within the T-shaped slot 120 of the second panel 102. The narrow section of the T-shaped slot 120 lines up with the channel 16, the overhang 18 of the head 14 preventing the panel connector 1 from pulling out of the T-shaped slot 120.
Referring to
The panel connector 1 is shown with body 10 and projecting rib 12, widening to a head 14. The head 14 is separated from the body 10 by a narrower channel 16, the head 14 including an overhang 18 to hold the panel connector 1 within a T-shaped slot.
The body 10 includes a body tip 20, the projecting rib 12 including a projecting rib tip 22.
The locking tab 30 can move in and out of the compression space 32 during installation, bending at a living hinge 34.
An insertion ramp 38 helps the locking tab to slide over intervening walls.
A keyhole slot 40 and keyhole void 42 allow for a secondary connector to be inserted and locked into the panel connector 1, allowing for the connection of additional devices. For example, feet for a cabinet, drawer front mounting hardware, or brackets for attaching molding.
In this embodiment, the edge-inserted embodiment, the body 10 tapers away from the head 14, resulting in a narrower body tip 20 as compared to the head 14.
This direction of taper allows for insertion of the panel connector 1 into a panel edge.
Referring to
The first panel 100 and the second panel 102 are shown, with the T-shaped slot 120 including an insertion section 122 and a locking section 124.
The head 14 (see
This process provides an alternative means of assembly, where the panel connector 1 is first placed into the first panel 100, then slid into the second panel 102.
Referring to
The pocket is a V-shaped stepped slot 110 with a wide slot section 112 and a narrow slot section 114. A tab depression 116 holds the locking tab 30 (see
Referring to
The second embodiment of the panel connector 1 includes a projecting rib 12 which includes the thickness of the body 10 but without the projection. The body 10 is reduced to the same shape and size as projecting rib 12, making the sides flat. The tab depression/slot 116 continues around the perimeter of the pocket but is only used at the tip to serve as a latch for locking tab 30.
With the taper reversed, the projecting rib 12 can pivot from the edge, using a guiding protrusion, downward into pocket 130 from the top, rather than being slid into the edge. The panel connector 1 seats into the pocket 130, the locking tab 30 snaps into the tab depression 116, locking the panel connector 1 in place.
The body 10 necks down between the head 14 and body 10, preventing the body 10 from being pulled out of the edge of the first panel 100.
Further shown are optional teeth 50. The teeth 50 lock into the material of the second panel 102, minimizing sliding of the panel connector 1 inside the T-shaped slot 120.
Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction, and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
This application is a continuation/continuation-in-part of U.S. Pat. App. Ser. No. 62/931,271, filed Nov. 6, 2019, titled Panel connector.
