- the present invention relates generally to structural insulated panels for use in custom-designed and prefabricated walk-in refrigerator and freezer spaces. More specifically, the present invention relates to an adjustable cam-strike system and method for manufacturing same, for use in the construction of custom designed walk-in refrigerator and freezer spaces.
- Walk-in refrigerator and freezer spaces, incubating spaces, and prefabricated insulated structures, such as dwellings, are typically manufactured and assembled using pre-fabricated insulated structural panels joined together to define the enclosed space.
- the structural panels provide insulation to maintain the temperature inside the walk-in space using as little energy as possible.
- the panels are typically joined together using latches and cam-strikes.
- Each panel is typically constructed with either a latch or cam-strike on each edge of the panel, so that when the panels are fitted into a structure, the latch of one edge engages the cam-strike of an adjacent panel.
- wall panels that are typically fastened to floor and ceiling rails also have a cam-strike and/or latch installed.
- the panels are manufactured with great precision, such that each panel has the latch and cam-strike in the same position(s) from panel to panel, and the panels are of precisely the same width.
- each latch and cam-strike are placed in a predetermined position within a slot that is fashioned to house the cam-strike, but no longitudinal movement along the slot is permitted or possible. In such a configuration, once the insulated panel is filled with foam, the cam-strike and latch mechanism are locked in place by the expansion of the foam around the cam-strike and latch devices, in their respective locations.
- a cam-strike having a striker pin is disposed through a lock plate disposed over a slotted structural member.
- a cover plate is placed over the cam-strike plate and lock plate against the structural member.
- the structural member is covered with sheathing on all sides and filled with expanding insulating foam. The expansion of the foam within the space created by the structural members and the sheathing veneer holds the cam-strike in place between the lock plate and the cover plate through friction.
- the cam-strike may be replaced by a latch.
- the invention may not include a lock plate, and may further also include a cam-strike or latch having an enlarged flange to disperse force from the insulating foam over a greater surface area of the cover plate.
- the latch, or latch, member is mounted between a lock plate and a cover plate in the same or similar manner as the cam-strike.
- the location of the cam-strike plate and the latch can be moved longitudinally within the slot of the structural member to provide for the alignment of the cam-strike pin and the latch.

- FIG. 1A for example, two un jointed panels 20 are shown as part of an insulated structural wall 10 .
- Each structural panel 20 is constructed of vertical structural members 22 M/ 22 F and horizontal structural members 24 (which also may be constructed with male/female configurations, not shown).
- the structural members 22 and 24 may be constructed of wood, a composite, metal, or any other suitable structural material as would be understood by one of ordinary skill in the art.
- Structural panels 20 are typically constructed using sheathing 26 , which may be steel, aluminum, oriented strand board (OSB), plywood, or other suitable sheathing material, which is held into place so that an insulating material, such as closed-cell polyurethane foam 28 is blown or injected between the sheathing 26 .

- the insulated structural panel is primarily assembled by virtue of the closed-cell polyurethane foam 28 acting as an adhesive to hold the sheathing and structural members in place.
- Insulated structural panels 20 are further typically designed such that vertical structural members 22 (and horizontal members 24 ) include a tongue-in-groove design (not shown for members 24 ).
- a latch 30 and cam-strike 32 are typically disposed within the panels to facilitate joining the panels together. When the latch 30 is actuated to engage the cam-strike 32 , for example, the insulated structural panels are drawn tightly together, as shown in FIGS. 1B and 1C . Also shown are rails 40 M and 40 F.
- Each of structural panels 20 may include a rail 40 M configured as a male structural member having a latch 50 disposed therein, and configured to attached to rail 40 F having a female groove 42 F with a slot 44 F disposed there through in a suitable location for disposition of a cam-strike 52 .
- Rail 40 F is preferably configured to attach to a floor structure along the bottom edge of the attached structural panels 20 and defines the external boundary of an enclosed structure manufactured using the structural panels 20 .
- Rails 40 M and 40 F may be interchanged, such that the panel 20 includes a female rail 40 F which attaches to a rail 40 M.
- Structural panels 20 are secured to a floor structure via structural members 40 M and 40 F by engaging latch 50 and cam-strike 52 in a similar manner as the connection between adjacent panels 20 and latch 30 with cam-strike 32 .
- the width of the structural panel may be determined by the application for which the insulated structural panels are to be used. If a bad seal exists, over time, as the relatively warm and moist outside air travels through the joint 34 , condensation may form. In the case of an insulated structural panel system used for refrigeration, this condensation may remain in liquid form and become a source of potential mold or bacterial growth. In the case of insulated structural panel freezer systems, condensation formed a joint 34 can result in the formation of ice, which, when formed in, or within joint 34 can expand the joint. Expansion of this joint 34 further degrades the efficacy of the insulated structural panel system, especially at the joint 34 . Accordingly, a secure connection is needed between the adjacent structural panels, as well as the structural panels and the base of the structure.

Abstract
Description
- The present invention relates generally to structural insulated panels for use in custom-designed and prefabricated walk-in refrigerator and freezer spaces. More specifically, the present invention relates to an adjustable cam-strike system and method for manufacturing same, for use in the construction of custom designed walk-in refrigerator and freezer spaces.
- Walk-in refrigerator and freezer spaces, incubating spaces, and prefabricated insulated structures, such as dwellings, are typically manufactured and assembled using pre-fabricated insulated structural panels joined together to define the enclosed space. The structural panels provide insulation to maintain the temperature inside the walk-in space using as little energy as possible. The panels are typically joined together using latches and cam-strikes. Each panel is typically constructed with either a latch or cam-strike on each edge of the panel, so that when the panels are fitted into a structure, the latch of one edge engages the cam-strike of an adjacent panel.
- Additionally, wall panels that are typically fastened to floor and ceiling rails also have a cam-strike and/or latch installed. Typically, the panels are manufactured with great precision, such that each panel has the latch and cam-strike in the same position(s) from panel to panel, and the panels are of precisely the same width. In the prior art, each latch and cam-strike are placed in a predetermined position within a slot that is fashioned to house the cam-strike, but no longitudinal movement along the slot is permitted or possible. In such a configuration, once the insulated panel is filled with foam, the cam-strike and latch mechanism are locked in place by the expansion of the foam around the cam-strike and latch devices, in their respective locations. However, when the panel width and/or placement of the latch or cam-strike is out of manufacturing tolerances, continued installation of panels with a consistent width difference may cause the latch and cam-strike to fail in their respective alignment. Additionally, in very large applications, even in which the panels are within tolerances for width, the minute variances in width can cause “stack-ups,” whereby the repeated increased width eventually causes the latch and cam-strike to fail in alignment. For example, if each of a group of 100 panels is only 1/16 of an inch over width in a panel wall structure, by the time the last panel is installed to a floor rail manufactured within tolerances, the alignment will be off by 6.25 inches. In such situations, an adjustable latch or cam-strike is needed to ensure that the panels can be properly installed.
- Additionally, consistently misaligned panels can cause premature stress and wear of the latch systems. Slight adjustability of the cam-strike helps to alleviate this problem.
- Accordingly, it would be desirable to have a system that effectively accounts for slight variances in panel width from panel to panel, and for slight variances in manufacturing, within or outside of tolerances.
- In one embodiment of the invention, a cam-strike having a striker pin is disposed through a lock plate disposed over a slotted structural member. A cover plate is placed over the cam-strike plate and lock plate against the structural member. The structural member is covered with sheathing on all sides and filled with expanding insulating foam. The expansion of the foam within the space created by the structural members and the sheathing veneer holds the cam-strike in place between the lock plate and the cover plate through friction. In another embodiment, the cam-strike may be replaced by a latch. In one or more additional embodiments, the invention may not include a lock plate, and may further also include a cam-strike or latch having an enlarged flange to disperse force from the insulating foam over a greater surface area of the cover plate.
- During operation, the friction mounting of the cam-strike plate between the cover plate and structural member, which, once the foam insulation has cured, is static, allows the cam-strike pin location to be moved along the slot in the structural member.
- In another embodiment, the latch, or latch, member, is mounted between a lock plate and a cover plate in the same or similar manner as the cam-strike. In either embodiment, or in others in accordance with the present invention, the location of the cam-strike plate and the latch can be moved longitudinally within the slot of the structural member to provide for the alignment of the cam-strike pin and the latch.
- Other embodiments in accordance with the spirit and scope of the invention will become apparent to those of skill in the art.

FIGS. 1A and 1B generally show an insulated structural panel system that, when joined together, form a wall for a pre-defined or custom-built refrigerated space. InFIG. 1A , for example, two unjointed panels 20 are shown as part of an insulatedstructural wall 10. Eachstructural panel 20 is constructed of verticalstructural members 22M/22F and horizontal structural members 24 (which also may be constructed with male/female configurations, not shown). Thestructural members Structural panels 20 are typically constructed usingsheathing 26, which may be steel, aluminum, oriented strand board (OSB), plywood, or other suitable sheathing material, which is held into place so that an insulating material, such as closed-cell polyurethane foam 28 is blown or injected between thesheathing 26. - The insulated structural panel is primarily assembled by virtue of the closed-
cell polyurethane foam 28 acting as an adhesive to hold the sheathing and structural members in place. Insulatedstructural panels 20 are further typically designed such that vertical structural members 22 (and horizontal members 24) include a tongue-in-groove design (not shown for members 24). Alatch 30 and cam-strike 32, are typically disposed within the panels to facilitate joining the panels together. When thelatch 30 is actuated to engage the cam-strike 32, for example, the insulated structural panels are drawn tightly together, as shown inFIGS. 1B and 1C . Also shown arerails structural panels 20 may include arail 40M configured as a male structural member having alatch 50 disposed therein, and configured to attached torail 40F having afemale groove 42F with aslot 44F disposed there through in a suitable location for disposition of a cam-strike 52.Rail 40F is preferably configured to attach to a floor structure along the bottom edge of the attachedstructural panels 20 and defines the external boundary of an enclosed structure manufactured using thestructural panels 20. Alternatively, and as further shown herein,Rails panel 20 includes afemale rail 40F which attaches to arail 40M. -
Structural panels 20 are secured to a floor structure viastructural members latch 50 and cam-strike 52 in a similar manner as the connection betweenadjacent panels 20 and latch 30 with cam-strike 32. - The width of the structural panel may be determined by the application for which the insulated structural panels are to be used. If a bad seal exists, over time, as the relatively warm and moist outside air travels through the joint 34, condensation may form. In the case of an insulated structural panel system used for refrigeration, this condensation may remain in liquid form and become a source of potential mold or bacterial growth. In the case of insulated structural panel freezer systems, condensation formed a joint 34 can result in the formation of ice, which, when formed in, or within joint 34 can expand the joint. Expansion of this joint 34 further degrades the efficacy of the insulated structural panel system, especially at the joint 34. Accordingly, a secure connection is needed between the adjacent structural panels, as well as the structural panels and the base of the structure.

Cam-strike 520 may include alatch pin 522, a housing, 524, and aplate surface 526. In operation, when thelatch 500 with itslatch arm 502 are aligned opposite cam-strike 520 andlatch pin 522, a hex key (not shown) is inserted into the latchkey aperture 508 and rotated, thelatch arm 502 engageslatch pin 522 and draws thelatch 500 closer to the cam-strike 520, including whatever devices latch 500 and cam-strike 520 are mounted on or within.

In a preferred embodiment, the cover plate extends beyond the ends ofslot 44 by at least an inch, but there is no specific dimensional requirement regarding coverage, so long as the coverage is sufficient to prevent expanding insulating foam from entering theslot 44 or contactinglock plate 54 or cam-strike 52. -
FIG. 2B is similar toFIG. 2A , except that instead of cam-strike 52 being disposed through theslot 44, it islatch 50/500 that is disposed through the slot. Additionally, the femalestructural member 40F is replaced by malestructural member 40M. - The
lock plate 54 andcover plate 56 preferably have smooth surfaces to facilitate the cam-strike 52 (or latch 50) to slide along the abutted face ofcover plate 56. Thelock plate 54 and cam strike 52 (andflange 526 thereof, perFIG. 1D ), distribute the force over a larger surface area ofcover plate 56 to facilitate sliding movement of the cam-strike 52 along the slot. In another alternative construction, the cam-strike 52 is inserted through theslot 44 and covered by thecover plate 56 with no lock plate. Alternatively, the cam-strike flange 526 may be made larger to further distribute the force along the cover-plate 56. - For the assemblies shown in both
FIGS. 2A and 2B , once thecover plate 56 is placed over thelock plate 54 and either cam-strike 52 orlatch 50, respectively, thecover plate 56 is attached to thestructural member FIG. 3 (only shown forFIG. 2A /2B assembly). In the embodiment shown, a sealingmembrane 58 is used to cover thecover plate 56 and seal thecover plate 56 to thestructural member membrane 58 consists of a non-permeable membrane, such as tape, but the cover plate may also be sealed with any suitable material or compound, such as caulk, silicone sealant, glue, cloth, or any combination thereof, which preventsfoam 28 from ingress into the space between thecover plate 56,slot 44F, and thelock plate 54. Further shown, for example, is that thetape 58 is even overlapped over the sides ofstructural member 40F. While not required, this embodiment further ensures that nofoam 28 can infiltrate the cover plate/lock plate/cam-strike/latch assembly, slot, and other grooves and cuts in formed in the structural members and/or created by the assembly of the components described herein. After thecover plate 56 is secured to thestructural member 40F/M, the structural member is assembled with otherstructural members 40F/M and 22F/M as required for the shape of the panel. Once theexterior sheathing 26 is affixed to thestructural member 22, 40, on both sides of the panel, expandingfoam 28 is injected into the panel. Thefoam 28 expands to fill the volume created by thestructural members 22, 40 and thesheathing 26, and applies a force to thecover plate 56, the cam-strike 52 orlatch 50, and thelock plate 54, via theplate surface latch 50/500 or cam-strike 52/520, respectively, as shown inFIGS. 1D, and 2A and 2B . The force applied by thefoam 28 is related to the density of thefoam 28 used. In embodiments used for walk-in freezers and refrigerated spaces, the foam pressure is typically about 6 lbs/in2. - Once the
foam 28 has cured within thepanel 20, the assembly described herein may be adjusted as shown inFIG. 4 by applying force in the longitudinal directions defined by theslot 44, providing adjustment to alignlatch 50/500 and cam-strike 52/520, as needed. Depending on the density offoam 28 used within the panel, it may be necessary to use additional tools, such as ahammer 48 and drift 46 to precisely adjust the cam-strike 52 (or latch 50) by tapping it into place. - Assembly of the panels in accordance with embodiments of the invention is shown in accordance with
FIGS. 1A-1C . Additionally, therails 40M /40F may be manufactured as part of afloor panel 46 that is manufactured in a similar manner asinsulated panels 20, having the configuration shown inFIGS. 5 and 5A . Additionally, anend plate 60 may be included to support the outer edge ofrails 40M/40F to provide additional structural support. In such a configuration, thecover plate 56 may protrude beyond the exterior surface ofrails 40M/40F, which may create a gap allowing ingress of warmer air, and/or reducing the stability of thestructural panels 20. One solution (not shown), is to router a recess into the back ofrails 40M/40F so that thecover plate 56 fits flush with the surface of the back of therails 40M/40F. Alternatively,end plate 60 may be configured with a relief cut 62 as shown inFIG. 5 andFIG. 5A . The depth of relief cut 62 ofend plate 60 is sized to accommodate the depth ofcover plate 56, as shown inFIG. 5 . During assembly,structural member 40F (shown) is positioned atopend plate 60 such thatcover plate 56 is accommodated by the relief cut 62.Floor panel 64 withrelief 66 is positioned underneath the remainder ofstructural member 40F, adjacent toend plate 60. Therelief 66 infloor panel 64 is preferably of sufficient depth to accommodate the portion ofstructural member 40F not supported byend plate 60, such that thepanel 20 sits substantially level on top ofend plate 60 andfloor panel 64. - During installation, a
panel 20 is positioned withlatch 50 to engage cam-strike 52 (in embodiments with thelatch 50 in thepanel 20 and the cam-strike 52 in therail 40F). Thelatch 50 engages the cam-strike 52 by inserting a hex wrench (not shown) into hex slot 508 (FIG. 1D ) and rotatably engaging thelatch hook 502. Once thefirst panel 20 is installed, the second andsubsequent panels 20 are installed in the same manner. If thelatch 50 and cam-strike 52 are not aligned, then the cam-strike 52 may be adjusted along theslot 44 using adrift 46 andhammer 48, or by hand, or by other suitable method sufficient to overcome the friction between the cam-strike 52 and thecover plate 56. - While the present invention has been described in detail, it is not intended to be limited. Accordingly, various changes, variations, and substitutions may be made without departing with the scope of the invention as disclosed. For example, the cover plates, lock plates, and latches may be manufactured from ceramic, or other composite. The size of the flanges of the latches and cam-strikes may be modified to suit specific applications, and the scale of the components may be adjusted. Other variations will be obvious to those of ordinary skill in the art, and remain within the scope of the invention.
