While the various features of this invention are hereinafter illustrated and described as being particularly adaptable for providing an improved thermal insulating apparatus and a method of making such apparatus adapted for use in a window construction having a single slidable horizontal section, it will be appreciated that the various features of this invention can be utilized singly or in any combination thereof to provide a thermal insulating apparatus for windows, doors, or other similar constructions.
Therefore, this invention is not to be limited to only the embodiments illustrated in the drawings because the drawings are merely utilized to illustrate one of the wide variety of uses of this invention.
In the exemplary embodiment of this invention illustrated particularly in FIGURE 1 of the drawings, a window construction or window designated generally by the numeral 20 uitlizing the thermal insulating apparatus of this invention is illustrated. Window 20 has a pair of double thickness sections of glass panes comprising a fixed section designated by the numeral 21 and a movable section designated by the numeral 22.
Window section 22 in this illustration is movable horizontally on track means shown as a horizontal track 23, see FIGURES 2 and 3, suitably supported on the supporting structure for window 20. Movable section 22 utilizes a plurality of rotatable roller means or rollers each designated by the numeral 24 which enable moving such window in a horizontal rectilinear path in an essentially frictionless manner.
As seen in FIGURES 24 of the drawings, several modifications of the thermal insulating apparatus of this invention are utilized in both the fixed window section 21 and the movable window section 22. Such thermal insulating apparatus assures that condensation problems normally occuring due to different temperature and relative humidity environments on opposite sides of window 20 are essentially eliminated.
Window 20 has a pair of supporting frame means or side frame members at opposite side edges thereof designated generally by the numerals 30A and 30B and a bottom and top supporting frame member designated respectively by the numerals 30C and 30D. Members 30A-30D support and thermally isolated window 20 about the entire outer periphery thereof in an associated supporting wall means using basically one embodiment of thermal insulating apparatus and such embodiment will be designated generally by the numeral 30 and shown in FIGURES 5-7.
The specific configuration of apparatus 30 shown in FIGURES 57 is of top frame member 30D; nevertheless, the basic description will only be made once and is fully applicable to the other frame members 30A, 30B, and 30C by taking into account minor configurational changes in the metallic members of such other members.
Apparatus 30 has a thermal insulating member shown as a central insulating member 42 and structural member means shown as a pair of metallic structural members each designated by the numeral 43 and arranged on both sides thereof as seen in FIGURE 5. Thermal insulating member 42, in this example of the invention, has first projection means or a projection shown as a Wedge-like projection 44 extending from opposite side surface means thereof. Each metallic structural member 43 has first groove means 45 adapted to receive an associated projection means 44 therewithin upon being assembled together.
As seen in FIGURES 6 and 7 of the drawings, groove 45 is deformed around an associated projection 44 in a clamping manner without substantially Crimping or deforming such projection to provide an interlocked assembly comprised of members 43 on either side of thermal insulating member 42.
It will be appreciated that once groove 45 is deformed around an associated projection, portions of such groove of necessity contact such projection and may make minor indentations therein; nevertheless, the fastening action is provided by the interlocking configuration provided by ridged locking surface means shown as a ridge 58 in each projection 44 being interlocked by a cooperating ridged locking surface means shown as surface 59 of groove 45 upon deforming groove 45 into position about an associated projection, see FIGURE 7.
Once apparatus 30 is assembled and interlocked in the manner described, it is nondemountable, that is, it cannot be demounted or taken apart without damaging the various components comprising such nondemountable insulating apparatus 30. As used in this disclosure of the invention the word nondemountable emphasizes the fact that it is not normally expected that apparatus 30 or similar apparatus to be later described are to be taken apart or demounted once assembled to form integral units of the types shown. In fact any attempt to take apparatus 30 apart would probably result in sufificient damage to render the apparatus in question unuseable.
Each projection means 44, in the illustrated example, is provided in oppositely arranged surface means defining a pair of parallel spaced apart planes each designated by the numeral 48 in thermal insulating member 42. It will be appreciated that with this arrangement a metallic structural member 43 can be easily fastened in position on either side of member 42.
Member 42 also has groove means therein shown as a groove 50 adjoining each plane surface 48. Each groove 50 is adapted to receive an associated cooperating projection 52 provided in each member 43. Thus, it will be seen that interlocking of each structural member 43 with an associated side of the thermal insulating member 42 is provided by inserting projection 52 in an associated groove 50, placing groove 45 in clamping arrangement around an associated projection 44, and then deforming groove 45 about such associated projection to define spaced apart interlocking means at each side of thermal insulating member 42.
The manner of deforming groove 45 in surrounding relation about an associated projection 44 is seen in FIG- URE 6. Projection 52 of each member 43 is placed in an associated groove 50 while groove 45 thereof is placed in surrounding relation around an associated projection 44. Clamping means shown as a pair of clamps each designated by the numeral 49 is provided for compressing and holding member 42 sandwiched between members 43 on opposite sides thereof.
With the assembly thus clamped together by clamps 49, mandrel means shown as a mandrel 53 having a rotatable spool-like end 54 is provided for deforming grooves 45 in position. End 54 has a pair of spaced apart edges each designated by the numeral 55. Each edge 55 engages and deforms a nondeformed leg of groove 45 of an associated member 43 to deform such leg against an associated projection 44 to provide a firm interlocked assembly as illustrated particularly in FIGURE 7 of the drawings.
The overall window 20 is isolated from its surrounding supporting wall structure by thermal insulating apparatus 30 in the form of frame members 30AD; the detailed construction of which was previously described; however, each individual section 21 and 22 employs a plurality of additional thermal insulating apparatus each designated by the numeral 40 and shown in FIGURE 8. Each apparatus 40 is identical in basic performance to apparatus 30 and cooperates therewith to further assure window 20 does not have condensation problems.
As in the case of apparatus 30, apparatus 40, as used in window 20, has one basic configuration and several different modifications all of which have been given the same numeral designation followed by a different letter designation for each different modification. Insulating apparatus 40A is used at the top and bottom of window section 21 and similarly apparatus 40B is used at the top and bottom of window section 22. An apparatus 40C is used at both side edges of window section 21; however, window section 22 employs an apparatus 40D along one side edge and another apparatus 40E along the opposite side edge.
The detailed description of apparatus 40 will be made referring to FIGURE 8 of the drawings; nevertheless, such description is fully applicable to each apparatus 40A-40E taking into account the minor variations in certain metal components in each instance.
Apparatus 40 employs a centrally arranged insulating member 60 and a pair of structural metallic members each designated by the numeral 61 arranged on either side thereof.
In a similar manner as discussed in connection with apparatus 35, each structural member 61 on opposite sides of member 60 is not of the same detailed configuration even though it carries the same numeral designation. However, it will be appreciated that for the purposes of this invention the thermal insulating apparatus is defined essentially by those portions of metallic members 61 immediately adjacent thermal insulating member 60 and by thermal insulating member 60 so that the detailed configuration beyond the immediate vicinity of the interlocked portions is not of paramount importance.
Thermal insulating member 60 has projection means 62, including ridged surface means such as a ridge 64, extending from each opposite surface thereof. Each metallic structural member 61 has groove means 63, including ridged surface means 65, cooperating with projection 62 and ridge 64 thereof such that upon deforming groove 63 around projection 62. in a manner as previously described in connection with groove means 45 (and using similar deforming apparatus) a nondemountable insulating apparatus having improved thermal insulating properties and improved structural strength is provided.
As in the case of the embodiment of apparatus illustrated in FIGURES 5-7, the embodiment of FIGURE 8 provides unique interlocking action without substantial deformation of projection means in the central thermal insulating member provided as an integral part thereof.
Another embodiment of thermal insulating apparatus of this invention similar to the embodiment of FIGURES 5-7 is illustrated in FIGURES 911 of the drawings. Because of the basic similarity of construction and operating performance, the overall insulating apparatus of FIGURES 911 will be designated generally by the same numerals 30 as before followed by the letter designation M in this latter embodiment. In addition, similar com ponents of apparatus 30M even though not having the exact detailed configuration of corresponding components of apparatus 30 of the previous embodiment will be designated by the same numerals followed in this latter embodiment by the letter designation A and not described again.
Apparatus 30M comprises a central thermal insulating member 42A having a pair of essentially parallel spaced apart mounting surfaces 48A and groove means 50A adjoining each surface 48A. A structural member 43A is provided on each side of apparatus 30M and mounted against a surface 48A.
Each groove means 50A is adapted to receive a cooperating projection 52A provided in an associated metallic structural member 43A similar to member 43. Member 43A has groove means shown as a preformed groove 45A therein which is fixed in nature and not subjected to deformation as in the case of groove 45 of the previous v embodiment and as will be readily apparent from the once each projection means 44A is formed, it is not necessary to deform such member in order to provide a firm interlocking connection between members 43A and member 42A.
Clamping means is provided for clamping members 42A and 43A- together and such clamping means comprises a cooperating pair of clamps each designatedby the numeral 49A and corresponding to clamp jaws 49 of FIGURE 6.
Heating means is provided for heating an end portion shown as the top endv portion of member 42A which is made of a thermoplastic material. The heating means comprises a heating block 66A and a heating plunger assembly 67A to heat the upper end portion of thermoplastic insulating member 42A.
Heating plunger assembly 67A is urged away from heating block 66A by spring means shown generally at 70A. Thus, contact is not made with the upper end portion of thermoplastic member 42A except by overriding spring means 70A and at such time as heating block 66A is arranged in confining relation against the upper end portion of thermoplastic member 42A.
Upon holding members 42A and 43A in clamping means 49A and applying heat through heating block 66A and heating plunger 67A, the upper end portion of thermoplastic block 42A is caused to melt and flow in a plastic manner into groove 45A provided in each of the members 43A to interlock the members together upon cooling of assembly 30M.
Once the hot plastic material flows into grooves 45A it is not further deformed but remains intact and cools to form a solid nondeformed projection 44A. The locking action provided by groove 45A in association with projection 44A is particularly illustrated in FIGURE 11 of the drawings and is similar in nature and function to the interlocking action provided and illustrated in FIG- URE 7 of the drawings.
FIGURE of the drawings illustrates the action of the heating block 66A and the heated plunger assembly 67A as the upper end portion of the thermoplastic thermal insulating member 42A starts to flow into associated grooves 45A. The interlocked arrangement is provided in each assembly 30M by the unique manner of forming such assembly yet without deformation of projection means 44A thereof.
In the exemplary embodiment of this invention illustrated in FIGURES 12 and 13 a thermal insulating apparatus designated generally by the numeral 72 is illustrated. Insulating apparatus 72 has a central thermal insulating member means or central insulating member 73 preferably made of a thermoplastic material and a pair of structural metallic members each designated by the numeral 74 are provided in spaced apart parallel relation adjacent opposite sides of member 73. Apparatus 72 is formed by extruding or flowing plastic material defining member 73 around selected portions of members 74 and allowing it to solidify to form integral unit or apparatus 72 having high strength.
Apparatus 72 is used practically interchangeably with apparatus 30 previously described. Also (as in previous embodiments) the metal structural members on each side of member 73 have the same numeral 74 even though they are not identical in configuration in every respect because the configuration thereof remote from member 73 is not critical insofar as this invention is concerned.
Die means designated by the numeral 76 is provided and preferably arranged so as to support structural members 74 in parallel spaced apart relation. Die means 76 is suitably constructed and arranged to define channel means within its central portion and in this exemplary embodiment of the invention such channel means has a substantially rectangular peripheral outline corresponding to the peripheral outline of member 73 as particularly illustrated in FIGURE 13 of the drawings.
Each structural member 74 is supported by die means 76 so that selected portions thereof are supported within the rectangular channel means of die means 76. In particular, eac'h structural member 74 has projection means shown as a leg portion 78 which is arranged within such rectangular channel together with portions of each member 74 which adjoin an associated leg portion 78.
Leg portion 78 are arranged within the rectangular channel of die means 76 in parallel spaced apart relation and in this example thermoplastic material which is in a semi-molten or comparatively viscous state is flowed within such rectangular channel on both sides of each leg portion 78 as well as around portions of each member 74 adjoining an associated leg and allowed to solidify. The resulting apparatus or construction with the thermoplastic material solidified to define member 73 is shown in FIGURE 13.
Die means 76 has small groove means therein shown at a plurality of locations each designated by the numeral 77. Such groove means, in effect, increase the area of contact between thermoplastic member 73 and structural members 74 upon solidification of the semimolten plastic material and provide a construction having improved strength. As the semimolten plastic material flows within groove means 77, it tends to cool and solidify quite rapidly thereby tightly sealing the rectangular channel.
Once the thermoplastic material forming member 73 cools the die means 76 is easily moved away from the resulting thermal insulating apparatus 72.
A thermal insulating apparatus similar to apparatus 72 may also be formed using liquid plastic material which flows rather freely and then solidifies upon setting to define an integral unit similar to apparatus 72. In the case of such a free flowing plastic, die means 76 is placed snugly against portions of members .74 so as to define a comparatively tight rectangular channel means to confine the liquid plastic until it solidifies.
Another exemplary thermal insulating apparatus designated by the numeral 81 is shown in FIGURE 14 of the drawings. Apparatus 81 is formed in a similar manner as apparatus 72 and utilizes die means 83 to define a substantially rectarigulan c'hannel means within which a selected portion of a single elongated structural member is supported. Die means 83 has a plurality of groove means 84 which serve a similar function as groove means 77 provided in die means 76 as previously explained.
A thermoplastic material is flowed around the selected portions of member 85 within the rectangular channel defined by die means 83 and allowed to solidify to define thermal insulating member 82. The resulting apparatus is shown in FIGURE 14 with the thermoplastic material solidified in position.
It will be appreciated that in some applications only one elongated structural member is required having a portion thereof thermally isolated by placing a thermoplastic material therea-round. The technique shown in FIGURE 14 enables thermal isolation of a portion of a structural member in a simple and inexpensive way.
Each thermal insulating apparatus 72 and 81 has been formed by extruding or flowing a thermoplastic material around structural member means and allowing it to solidify. However, it will be appreciated that it may be desirable in some applications to hold an elongated block of suitable plastic material in a suitable fixture and then mechanically force structural member means therethrough. Such mechanical forcing may be achieved to define elongated constructions similar in mechanical arrangement of components to apparatus 72 as well as similar to apparatus 81 and the length of the elongated constructions thus formed would of course depend on the application and the characteristics of the structural members and thermal insulating member utilized.
This forcing (extruding) technique may in some instances be used in conjunction with the extrusion forming of a metal structural member directly out of an extrusion die into an elongated block of plastic material,
provided that the temperature of the metal member as it leaves its die is compatible with the melting point of the plastic material.
Window 20 of this exemplary illustration of the invention employs double thickness glass panes in each section 21 and 22 and an air space is provided between the glass panes in each section for better thermal insulation. In addition, window sections 21 and 22 are each mounted against associated portions of apparatus 30C and 30D at the bottom and top thereof respectively using a pair of wick-like insulating strips therebetween for each window and each designated by the numeral 90. A plurality of similar strips, each also designated by the numeral 90, is also provided between opposite sides of window sections 21 and 22, see FIGURE 2, and adjoining structure.
Each strip 90 may be made of any suitable material to provide a weathertight construction for window 20. Also, the wick-like or yielding construction thereof provides a construction which is less likely to rattle.
There maybe some tendency for slight condensation on surface means indicated by the numeral 91 in FIGURE 3, for example, In the event such condensation occurs it will be appreciated that the configuration of apparatus 30C confines such condensation and weep holes each designated by the numeral 92 are provided in member 300 to allow flow toward the outside of the window construction.
Movable window section 22 in this example of the invention is moved horizontally on track 23 by grasping handles 95 provided adjoining opposite side edges of section 22 and rolling such window along its track. In some applications of this invention it may be desirable to provide a movable window section which can be locked at a plurality of positions along its track to which it is moved. A window locking apparatus for this purpose is illustrated in FIGURES 15 and 16 of the drawings and designated by the numeral 100.
Apparatus 100 is shown installed basically along one side edge of movable window section 22 and thus components of such window section, track, etc. which were previously described will not be described again although the same reference numerals will be used for identical members.
Apparatus 100 has a handle assembly 101 suitably fastened to a side edge indicated at 102 of window 22. Assembly 101 has a downwardly projecting stop 103 which is adapted to engage a cooperating toothed strip 104 supported at the bottom of window 22 parallel to track 23.
Assembly 101 with its stop 103 are suitably supported for vertical sliding movement and a suitably supported spring 105 yieldingly urges handle assembly 101 and its stop 103 downwardly against strip 104.
Strip 104 has a plurality of spaced apart teeth 106 therealong and the action of spring 105 causes stop 103 to engage a tooth 106 and prevent window section 22 from being opened further. It will be noted that the con- [figuration of the lower tip of stop 103 and the upper configuration of each tooth 106 is such that window section 22 can be pushed closed, with spring 105 being compressed as stop 103 is pushed to the right past a tooth, but (except by pulling up on handle assembly 101) can not be opened further.
Handle assembly 101 has an upper projecting portion 110 having a downwardly hooking terminal end 111. The hooking end 111 enables handle 101 to be fastened in its upper (unlocked) position over a cooperating projection 112 fixed to section 22 for free horizontal movement toward both an open position or a closed position.
Thus, it is seen that handle assembly 101 enables looking of window section 22 at a plurality of positions, corresponding to the number of teeth 106, to prevent further opening thereof or it may be hooked open using hook 111 to prevent free movement in both directions. It will be noted that apparatus utilizes thermal insulating apparatus 40 as a part thereof.
The manner of forming the improved apparatus 30 and 40 of this invention wherein a thermal insulating member is provided with preformed projections therein and then metallic members are clamped therearound by deforming groove means in such metal members makes it possible to provide an improved assembly without requiring that the individual components be precisely formed for sliding fit or the like. Also because the extent of deforming groove means of the metal members comprises deformation until contact is made with an associated thermal insulating member without appreciable deformation of such insulating member also makes it possible to reduce the control of dimensional tolerances on the mating members.
Each apparatus 30M, 72, and 81 is also easily formed in an inexpensivemanner without precise dimensional control of component members as will be apparent from the drawings and previous description of such members.
Each exemplary apparatus 30 and 30M of this invention is constructed for optimum thermal insulation. In each instance the central thermal insulating member is necked down in the form of an hour glass or the like. Upon interlocking a metallic member in position against surface 48 or 48A, for apparatus 30 and 30M respectively, a roughly triangular air space is provided between such central insulating member and the outer metallic member. Such triangular air space is designated by the numeral 113 in apparatus 30 and 113A in apparatus 30M.
The structural members employed in the various embodiments of insulating apparatus presented herein are all preferably made of metal containing aluminum thereby providing high strength, light weight, while being corrosion resistant.
The thermal insulating members of the various embodiments of this invention may be made of any suitable rubber-like or plastic material such as vinyl plastic, polyethylene, or the like, for example. The plastic material is usually of a type which is easy to mold or work and lends itself to being for-med by extruding through suitable die means.
Terms such as bottom, top, sides, inside, outside, etc. have been used throughout this application for ease of description and merely to correspond to the illustrations in the drawings. Such terms should not be considered as limiting the scope of this invention in any way.
Thus, it is seen that an improved nondemountable thermal insulating apparatus has been provided which 1 s of simple and economical construction and which 1s particularly adaptable for use in constructing window means, door means, and the like.
Further, this invention provides an improved method of economically fabricating such apparatus.
