Magnetic panel assembly for seamless installation and related servicing method

Abstract

A device includes a base component formed from metallic, polymeric, or composite materials, exposing a frame-receiving surface. A removable frame is maintained on the frame-receiving surface in response to a perpendicular component of a magnetic field emitted between the base component and the removable frame. The removable frame exposes a panel-receiving surface and has one or more prongs extending laterally away from an external lateral surface. A panel is fixably attached on the panel-receiving surface, with outside dimensions determined to account for the laterally extending prongs. A method for accessing internal parts involves inserting a grabbing tool to engage at least one prong and pulling the removable frame away until the magnetic field is insufficient to maintain the removable frame on the base component, enabling inspection or maintenance of internal elements.

MAGNETIC PANEL ASSEMBLY FOR SEAMLESS INSTALLATION AND RELATED SERVICING METHODPriority statement

[0001] This non-provisional patent application claims priority based upon the prior U.S provisional patent application entitled "PANEL ASSEMBLY", application number 63 / 667,737, filed on 2024-07-04, in the name of MEDIA GRAPH DEPOT INC., which is hereby incorporated herein in its entirety.Technical field

[0002] The present invention relates to a panel assembly and, more particularly, to a lighting panel assembly.Background

[0003] Ceiling tiles have been used for a long time. Lighting fixtures typically replace some of the ceiling tiles. There are obvious demarcations visible between the tiles and between the ceiling tiles and the lighting fixtures.

[0004] Providing seamless ceiling surface is complex and, even when one achieves it, servicing the lighting fixtures thereof is cumbersome. The present disclosure provides solutions that may help to alleviate such problems.Summary

[0005] This summary is provided to introduce a selection of concepts in a simplified form that may be further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0006] In a first aspect, the technique described herein relates to an assembly including a base component emitting a magnetic field having a component perpendicular to the base component, the base component exposing a frame-receiving surface. The assembly may also include a removable frame maintained on the frame-receiving surface in response at least tothe perpendicular component of the magnetic field, the removable frame exposing a panelreceiving surface and having prongs extending laterally away from an external lateral surface. The assembly may furthermore include a panel fixably attached on the panel-receiving surface of the removable frame, outside dimensions of the panel being determined to account for the laterally extending prongs of the removable panel when fixably attached thereon.

[0007] In embodiments, implementations may include one or more of the following features. The base component may optionally emit the magnetic field from a plurality of selectively-positioned polarized magnets. The removable frame may include a plurality of oppositely-polarized magnets positioned in relation to the selectively-positioned polarized magnets.

[0008] In embodiments, each of the laterally extending prongs may include a biasing mechanism in a body thereof maintaining a sloped plunger extended from the external lateral surface. The sloped plunger may retract into the body of the prong to let through a grabbing surface of a tool inserted from an exposed surface of the panel towards the base component to selectively detach the removable frame from the base component.

[0009] In embodiments, Additionally or alternatively, the base component may house a light source in an internal region. The panel may include a light diffuser (e.g., to scatter light), and the panel may present one or more perforations (e.g., to allow partial light passage).

[0010] Ain embodiments, the frame-receiving surface of the base component may include lateral ledges that may ensure lateral stability of the removable frame with respect to the base component. The external lateral surface may therefore be continuous from the base component to the removable frame.

[0011] Optionally, the base component and the removable frame may be linked by an attachment mechanism limiting the maximum distance therebetween when the removable frame may be pulled from the base component.

[0012] Optionally, the attachment mechanism may include a cable maintained between the base component and the removable frame, the cable may be attached at one end to one end of a spring, another end of the cable may be fixed to a slidable holder, the cable may be routed through a pulley assembly, where the spring may be fixed at another end to one of thebase component or the removable frame and the slidable holder may be maintained in the other one of the base component or the removable frame. A distance between the fixed end of the spring and the pulley assembly may be set and a spring constant of the spring may be selected considering a force that maintains the removable frame on the frame-receiving surface. Optionally, the slidable holder may be selectively detachable therefrom through a slot.

[0013] Optionally, multiple instances of the attachment mechanism may be included.

[0014] In embodiments, the panels from the plurality of assemblies may provide a continuous visible surface, a grabbing tool may be insertable between panels in alignment with the prongs to detach one of the removable frame.

[0015] In a second aspect, the technique described herein relates to a system of multiple assemblies that may be provided whereby the panels from the plurality of assemblies may be arranged side by side to present a continuous visible surface. Each removable frame may include prongs positioned such that a grabbing tool may be inserted between adjacent panels in alignment with the prongs to detach one of the removable frames.

[0016] In a third aspect, the technique described herein relates to a method for accessing internal parts of an assembly. With a panel of the assembly forming a flat surface with one or more juxtaposed elements, a grabbing tool may be inserted between the assembly and one of the juxtaposed elementsthrough the flat surface. The assembly may include a base component exposing a frame-receiving surface, a removable frame maintained on the frame-receiving surface in response at least to a perpendicular component of a magnetic field emitted between the base component and the removable frame, the removable frame exposing a panelreceiving surface and including one or more prongs extending laterally away from an external lateral surface, and the panel fixably attached on the panel-receiving surface of the removable frame. Once the grabbing tool has engaged one of the one or more prongs, the removable frame may be pulled away from the base component such that the magnetic field is insufficient to maintain the removable frame on the base component. The prongs may be shaped to provide a contact point for the grabbing tool, and the removable frame may be detached in a manner that permits access to an internal region behind the panel. The panel may be reattached when the removable frame is realigned with the base component and the magnetic field again exerts a sufficient retaining force.

[0017] Optionally, at least partially detaching the removable frame from the base component (i.e., by overcoming the perpendicular component of the magnetic field) may be done, thereby enabling servicing of one or more internal parts. Reattaching the removable frame to the base component and pushing the removable frame toward the base component such that the magnetic field is sufficient to maintain the removable frame on the base component may then be done. Examples of partial detachment may include applying a pulling force at the external lateral surface of the removable frame or engaging one or more prongs that extend laterally from the removable frame to facilitate removal.

[0018] Optionally, the base component and the removable frame may be linked by an attachment mechanism limiting the maximum distance therebetween when the removable frame is pulled from the base component, the attachment mechanism having a cable maintained between the base component and the removable frame, the cable being attached at one end to one end of a spring, another end of the cable being fixed to a slidable holder, the cable being routed through a pulley assembly, where the spring is fixed at another end to one of the base component or the removable frame and the slidable holder is maintained in the other one of the base component or the removable frame, where at least partially detaching the removable frame from the base component is performed by detaching the slidable holder through a slot.

[0019] In embodiments, the method may include modifying a distance between the fixed end of the spring and the pulley assembly thereby affecting a force that maintains the removable on the frame-receiving surface. Implementations of the described techniques may include hardware, a method or process, or a computer tangible medium.Brief description of the drawings

[0032] A comprehensive explanation may be provided to illustrate how various structural components, functional elements, and potential manufacturing considerations may be organized and employed in one or more assemblies. Each assembly may incorporate a basecomponent formed from metallic, polymeric, or composite materials that may house interior regions to support wiring, electronics, or optional illumination sources. A removable frame may be adequately dimensioned to be maintained on a frame-receiving surface of the base component and may further expose a panel-receiving surface. The removable frame may include magnets, prongs, or other retention elements that may facilitate selective attachment and detachment from the base component. A panel made from metallic, polymeric, or composite materials may then be fixably attached on the panel-receiving surface, thereby defining a boundary, partition, or covering. One or more sub-assemblies may be juxtaposed side by side so that the panels collectively present a continuous visible surface, and optional perforations or light-diffusing features may be integrated to allow partial passage of light.

[0033] Reference is now made concurrently to the drawings Figures 1 to 9. Figure 1 shows an example of an assembly 100, which may include a base component 110 and a removable frame 120 maintained in position by one or more magnets 702 and 704. The assembly 100 may be formed from metallic, polymeric, or composite materials. The assembly 100 may further incorporate a panel 800 that may be fixably attached on the removable frame 120 to define a boundary or covering.

[0034] Figure 2 shows an example of a removable frame 120 of the assembly 100. The removable frame 120 may have a profile 122 configured to align with the base component 110 and may present a panel-receiving surface on which the panel 800 is secured.

[0035] Figure 3 shows a base component 110 of the assembly 100, which may have a profile 112 providing a frame-receiving surface sized to receive the removable frame 120. The base component 110 may be formed from metallic, polymeric, or composite materials and may optionally house internal elements such as wiring or light sources.

[0036] Figure 4A is lateral sectional view of the assembly 100, illustrating how the removable frame 120 and the panel 800 may create a continuous surface.

[0037] Figures 4B and 4C are views of an attachment mechanism 600 between the base component 110 and the removable frame 120, which may optionally be provided to facilitate access to housed internal elements.

[0038] Figure 5 presents a section view of a profile 112 of the base component 110, whereas Figure 6 presents a section view of a profile 122 of the removable frame 120, highlighting how the removable frame 120 may be retained in part by the perpendicular component of a magnetic field between the base component 110 and the removable frame 120.

[0039] Figure 7 is a perspective view of exemplary magnets 702 and 704, which may be arranged in a polarity configuration generating an attractive force sufficient to maintain the removable frame 120 in position.

[0040] Figure 8 is a top view of an exemplary panel 800 of the assembly 100, showing how the panel 800 may be dimensioned to fit over the removable frame 120 and conceal internal regions.

[0041] Figure 9 shows views of an exemplary prong 900, which may extend laterally from an external lateral surface of the removable frame 120 to facilitate insertion of a grabbing tool for selective detachment of the removable frame 120 from the base component 110.

[0042] The assembly 100 comprises a base component 110 emitting a magnetic field having a component perpendicular to the base component 110, wherewith the base component 110 may expose a frame-receiving surface 116. A removable frame 120 may be maintained on the frame-receiving surface 116 in response, at least in part, to the perpendicular component of the magnetic field, wherewith the removable frame 120 may expose a panel-receiving surface 126 and may have at least one prong 900 extending laterally away from an external lateral surface 128. A panel 800 may be fixably attached on the panelreceiving surface 126 of the removable frame 120. Outside dimensions of the panel 800 may be determined to account for the laterally extending prong 900, whereby the panel 800 may overlap at least partially with the prong 900. The assembly 100 may be positioned on ceilings, walls, orfloors, depending on needs. Skilled persons will readily be able to adapt the teachings provided herein to those different contexts.

[0043] The base component 110 may emit the magnetic field from a plurality of selectively-positioned polarized magnets 704 labeled 720 / 710, which may be oriented to provide a predetermined magnetic pull. The removable frame 120 may include a plurality of oppositely-polarized magnets 702 labeled 710 / 720, positioned with respect to the magnets704 so that a target force is exerted therebetween. The target force may represent an intended level of magnetic retention sufficient to hold the removable frame 120 onto the base component 110 while allowing selective detachment. In some embodiments, the magnets 704 or 702 may be replaced with ferrous material, such as steel or cast iron, that may interact with the magnetic field in a similar manner.

[0044] The profiles 112 and 122 may be extrusions of a non-magnetic alloy, for example an aluminum-based composition, shaped to accommodate the magnets 704 or 702 while providing structural support. In other embodiments, the base component 110 or the removable frame 120 may be made completely or partially of ferrous material to directly engage with the magnetic field. In some embodiments, one or more electromagnets (not shown) may be used instead of, or in addition to, the magnets 704 or 702.

[0045] Receiving slots 119 and 129 may be incorporated in the profiles 112 and 122 to hold and mechanically retain the magnets 704 or 702 in a perpendicular orientation. Additional stoppers (not shown), such as screws or rubber clips, may be inserted in the receiving slots 119 and 129 to fix lateral positions of the magnets 704 or 702. Such a configuration may allow stable placement and alignment of the magnets 704 or 702 within the assembly.

[0046] The laterally extending prong 900 may be formed from metallic, polymeric, or composite materials and may include a biasing mechanism (not shown) housed within a body 910 to maintain a sloped plunger 920 extended from an external lateral surface. The slot 940 in the body 910 of the prong 900 may receive the biasing mechanism (e.g., a spring), thereby permitting the sloped plunger 920 to remain in a protruding position unless acted upon by an external force. The sloped plunger 920 may retract into the body 910 of the prong 900 to let through a grabbing surface of a tool inserted from an exposed surface of the panel 800 towards the base component 110, enabling selective detachment of the removable frame 120 from the base component 110. A lip 930 of the plunger 920 may receive the grabbing surface of the tool upon insertion. In other embodiments, the prong 900 may be a screw-type prong (see Figures 9F and 9G), with a tip and / or head shaped to define a lip or similar feature (e.g., a swivel clamp screw to receive the grabbing surface of the tool.

[0047] The assembly 100 may further comprise a light source 130, which may be housed in a portion of the assembly 100 positioned to direct illumination towards the panel 800. Thepanel 800 may comprise a light diffuser 810 that may be formed from polymeric, glass-based, or composite materials allowing partial or focused transmission of light from the light source 130. The light diffuser 810 may present sharp fold edges arranged so that the light diffuser 810 is sandwiched between the panel 800 and the profile 122, thereby maintaining a stable alignment of the light diffuser 810. One or more perforations 820 may be included in the panel 800 to permit additional light transfer orto provide ventilation, and such perforations 820 may be regularly spaced or formed in a decorative pattern. A back panel 140 may be positioned beneath the light source 130 to enhance reflectivity, and this back panel 140 may be formed from metallic or coated polymeric materials configured to redirect light through the panel 800.

[0048] A lateral position of the one or more laterally extending prongs 900 along one or more sides of the removable frame 120 may be predetermined (e.g., fixed distance from one or more corners or a center of one or more sides such that alignment with insertion points for a grabbing tool may be facilitated). The removable frame 120 may also include a position indicator (not shown) on a visible surface of the removable frame 120 (e.g., on the profile 122), the panel 800, and / or on the light diffuser 810). The position indicator may be integrated with other visible symbols or patterns on at least one visible surface of the removable frame 120 (e.g., on the profile 122, the panel 800, and / or on the light diffuser 810) to identify the location of the one or more prongs 900. The position indicator may comprise a distinct marking, groove, color variation, or decorative element dimensioned to guide the insertion of a grabbing tool.

[0049] The frame-receiving surface 116 of the base component 110 may incorporate a lateral ledge 118 configured to maintain the removable frame 120 in a stable position in a direction parallel to the plane of the base component 110. The external lateral surface 128 may therefore extend continuously from the base component 110 to the removable frame 120.

[0050] In some instances, the removable frame 120 may be linked to the base component 110 via an attachment mechanism 600. The attachment mechanism 600 may be configured in various ways to allow the removable frame 120 to be pulled away from the base component 110 (for example, to provide access to interior components) while ensuring that the removable frame 120 remains linked to the base component 110 (for example, to permit an intermediate position during installation or to prevent the removable frame 120 from falling or becoming unwieldy when pulled away). The attachment mechanism 600 may include a bracket, a tether,or an extendable arm pivotally or slidably engaged with the base component 110 and the removable frame 120 such that a partial detachment may occur without complete separation. The removable frame 120 may thus be moved into an intermediate position for servicing or alignment tweaks, thereby enabling convenient handling while maintaining a controlled link with the base component 110.

[0051] One or more cables or wires 620 may be included to secure the removable frame 120 to the base component 110, where lengths of the cables 620 may define a maximum distance between the removable frame 120 and the base component 110. In the depicted example of Figures 4B and 4C, a single cable 620 is shown. The cable 620 is attached at one end to a spring 610 through a linear nut 616. The spring 610 is fixed to the base component 110 by a screw 614 inserted in a fixably slidable holder 612. The fixably slidable holder 612 may be inserted in one of the groves 117, 115. The other end of the cable 620 may be fixed to a slidable holder 632, which may be inserted in the slot 129. The fixably slidable holder 612 may be shaped so that the spring 610 is anchored with respect to the base component 110, while the slidable holder 632 may permit controlled movement of the cable 620, thereby allowing the removable frame 120 to be pulled away from the base component 110 up to the maximum distance set by the cable 620.

[0052] In the depicted example, the spring 610 is mounted parallel or substantially parallel to the profile 112 of the base component 110, and the slidable holder 632 maintains the wire 620 perpendicular to the profile 122 of the removable frame 120. A pulley assembly 622 is fixed in the base component 110 by a screw 624, and allows the cable 620 to be routed towards the slidable holder 632. The pulley assembly 622 may be inserted in the same one as the fixed end of the spring 610 or may be inserted in a different one of the groves 117, 115. A hole may be made in the profile 112 through the groove 119 for the cable 620 to reach the slidable holder 632. A groove 127 may be provided in the slot 129 of the profile 122 to allow the slidable holder 632 to be selectively inserted thereinto.

[0053] Multiple attachment mechanisms 600 may be provided. The force exerted by the spring 610 may be set by selecting a k constant for the spring 610 and may be further calibrated by varying the distance between the fixably slidable holder 612 and the pulley assembly 622. The force exerted by the spring 610 is to be determined by considering the target force that holds the removable frame 120 onto the base component 110. The spring 610 may contributeto the target force that maintains the removable frame 120 onto the base component 110 while allowing selective detachment. Skilled person will appreciate that parts of the attachment mechanism 600 may be distributed differently between the base component 110 and the removable frame 120 (e.g., the spring 610 and the pulley assembly 622 being mounted in the removable frame 120). A subset of the cables or wires 620 may be detachably attachable so that the removable frame 120 may be angled away from the base component 110 in a manner similar to a hinge (for example, by removing the slidable holder 632 through the groove 127 from some of the attachment mechanisms 600 present). Alternatively, or additionally, the attachment mechanism 600 may comprise (not shown) one or more of a hinge, one or more wires, and / or one or more extending clips. The hinge may be affixed along one edge such that the removable frame 120 may pivot away from the base component 110. One or more extending clips may be introduced to connect the removable frame 120 to the base component 110 through slots or receptors (for example, spring wire clips relying on compression and spring tension). The lengths of the extending clips may define a maximum distance between the removable frame 120 and the base component 110. Some or all of the clips may be detachably attachable to allow partial or complete disengagement of the removable frame 120 from the base component 110. In some configurations, the attachment mechanism 600 may include a combination of hinge(s), wire(s), and / or clip(s), for example, disengageable clips on one side with fixed wires on the other side, so that the removable frame 120 may pivot while remaining partially connected to the base component 110.

[0054] The description of the present invention is presented for illustration but is not intended to be exhaustive or to limit the disclosed embodiments. Many modifications and variations may be apparent to those of ordinary skill in the art. The embodiments may be chosen to explain principles of the invention and possible practical applications, and to enable those of ordinary skill in the art to implement various embodiments with modifications that may be suited to other contemplated uses. The various embodiments may incorporate structural or functional alterations to address different design requirements. For instance, an arrangement may include alternate materials, additional connectors, or expanded circuitry to accommodate a variety of operational conditions. Such configurations may be combined in any suitable manner, thereby permitting further adaptation to particular environments or additional constraints while adhering to the scope of the disclosed embodiments so that practical implementation may be achieved.
