3,307,294 ENTRANCE CONSTRUCTION Norman Bienenfeld, Cranston, Byron H. Abedon, Provideuce, Richard E. Primeau, East Providence, and Arthur I. Blackmail, Cranston, R.I., assignors, by mesne assignments, to The Alumiline Corporation, Pawtucket,

R.I., a corporation of New York Filed Mar. 23, 1964, Ser. No. 353,767 9 Claims. (Cl. 49-381) The present invention relates to an entrance construction. More particularly the present invention relates to an entrance construction that comprises a door assembly and frame therefor, the door assembly and frame including horizontal and vertical members that are formed of a thin gauge metallic material that is roll formed to a tubular configuration and that is secured in position by an interior lock seam.

Metal materials for use in commercial entrance constructions are well known and for many year-s the members that defined such construct-ions have preferably been formed of extruded aluminum. Commercial entrance constructions constructed of aluminum have been employed with some degree of success. However, aluminum does have its deficiencies in that it has been known to pit and discolor, particularly when colors other than the natural color of the metal is applied to the surface thereof. It is known that stainless steel is a most desirable material for use in door constructions because of the inherent characteristics of the metal. steel has not been practical for use in commercial entrance construction because of the relatively high cost involved in the fabrication thereof. Prior to the instant invention the heretofore known stainless steel door constructions included an inner filler on which the stainless steel metal material was shaped and formed. This resulted in an unusually durable construction but this form of door was also extremely heavy and expensive to fabricate.

The present invention includes an entrance door construction that is fabricated of a stainless steel material but that eliminates the heretofore known objectionable features of stainless steel. In the present invention, a relatively thin gauge stainless steel is utilized, the individual members that define the entrance construction being roll formed and locked in place by interlocking the longitudinal edges thereof to define an interior lock seam. Since stainless steel is used in fabrication of the members of the entrance construction, a unique corner clip is employed that is welded directly to the members. The technique of welding a stainless steel corner clip to the stainless steel members is unique in the present invention since in the prior known aluminum door constructions, welding of corner clips was not usually resorted to because of the relatively low melting point of aluminum. The corner clips as employed herein are also formed in a special shape and configuration to accommodate the interior lock seams of the entrance construction members. Since the memhers that define the entrance construction of the present invention are formed of a stainless steel material, a unique technique is utilized for securing panel retainers in place. This technique involves the use of special retainer clips that are so constructed as to provide for the snapping into place of the glazing or panel retainers. These special clips are further constructed so as to enable the panel or glazing retainers to be adjustably positioned, thereby accommodating for panels or glazing of varying thickness.

Accordingly it is an object of the present invention to provide an entrance construction wherein the members However heretofore stainless.

United States Patent G ice 3,307,294 Fuentes Mar. 7, 1967 thereof are formed of a relatively thin gauge stainless steel material and are roll formed to define an interior lock seam.

Another object of the invention is to provide a metallic entrance construction wherein the members thereof are joined at the corners by corner clips that are especially formed to accommodate lock seams located interiorly of the members.

Still another object is to provide a corner clip for use in an entrance construction, the corner clip being welded to the members that define the entrance construction at the corners thereof.

Still another object is to provide an entrance construction having members formed of a relatively thin gauge stainless steel material and including retainer clips that provide for the adjustable mounting of panel holding retainers.

Still another object is to provide a retainer clip for use in an entrance construction wherein the retainer clip is formed with laterally offset legs that provide for adjust ably mounting panel retainers thereon.

Other objects, features and advantages of the invention will become apparent as the description thereof proceeds when considered in connection with the accompanying illustrative drawings.

In the drawings which illustrate the best mode presently contemplated by us for carrying out our invention:

FIG. 1 is a front elevational view of the entrance construction embodied in the present invention wherein a frame defines a door opening and a door assembly is pivotally mounted on said frame in the opening.

FIG. 2 is a fragmentary perspective view of a portion of the frame of the entrance construction embodied herein showing the interconnection of a pair of horizontal sash members to a vertical sash member.

FIG. 3 is a perspective view of a corner clip for securing a horizontal sash member to a vertical sash member.

FIG. 4 is a perspective view of a corner clip that is employed in the securement of the vertical and horizontal sash members of the door assembly shown in FIG. 1.

FIG. 5 is a sectional view taken along lines 55 in FIG. 1.

FIG. 5a is a fragmentary sectional view similar to FIG. 5, showing the mounting of the door assembly glazing by the use of special retainer clips.

FIG. 6 is a sectional view taken on lines 6-6 in FIG. 5.

FIG. 6a is a fragmentary sectional view similar to FIG. 6 showing the location of the panel retainer that mounts the door assembly glazing in place.

FIG. 7 is a sectional view taken along lines 77 in FIG. 6.

FIG. 7a is a fragmentary sectional view similar to FIG. 7 showing the retainer clips that are used in the securement of glazing sashes in place.

FIG. 8 is an enlarged sectional view similar to FIG. 7a illustrating the interlocking of the panel retainers to the retainer clips that are secured to the sash members of the door assembly; and

FIG. 9 is an enlarged perspective view of one of the retainer clips embodied in the present invention.

Referring now to the drawings and particularly to FIG. 1, the entrance construction embodied in the present invention is generally indicated at 10 and includes a frame assembly generally indicated at 11 and a door assembly generally indicated at 12 that is mounted for pivotal movement in the frame assembly 11. The frame assembly 11 which defines an opening in which the door assembly 12 is located includes an upper horizonal frame member 14 and vertical frame members 16 and 18. Since the entrance construction of the present invention is adapted to be utilized primarily in commercial installations, it is not necessary to provide a threshold for the frame although such a threshold may be employed if it is practical or so desired. As further shown in FIG. 1, additional frame members 20 and 22 may be incorporated in the frame assembly and are constructed and secured in place in the same manner as the members 14, 16 and 18. Panels 24 formed of glass or other decorative material such as plastic, metal or wood are secured to the frame members by any convenient means and may be mounted in place by a unique technique to be described hereinafter in connection with the door assembly 12.

One of the novel features of the present invention is in the use of a relatively thin gauge metallic material that is adaptable for roll forming into a tubular construction. In the preferred form of the invention, stainless steel is employed, but is formed of a relatively reduced thick ness to define a thin gauge material, the thin gauge stainless steel being adaptable for roll forming into the tubular configuration of the members that cooperate to define the door construction illustrated in FIG. 1. Referring to FIGS. 2, 5, 6 and 7 the tubular members that form the frame and door assembly of the door construction are illustrated and as shown, these members have been rolled to a tubular configuration and are interlocked interiorly thereof by a lock seam. In FIG. 2 the horizonal frame member 14 is shown comprising an upper wall 26, sidewalls 28 and 30 to which are joined coextensive bottom walls 32 and 34. The walls of the horizontal frame member 14 have been rolled to the configuration as illustrated in FIG. 2 and the edges thereof indicated at 36 and 38 are interlocked in a lock seam which forms a longitudinally extending rib indicated at 40. As shown in FIGS. 5, 6 and 7 the vertical and horizontal sash members that define the door assembly 12 are roll formed in a similar manner to that just described and are also interlocked by an interior lock seam.

Referring again to FIG. 2 the frame member 14 is shown being secured to the vertical frame member 18 by a corner clip that is generally indicated at 42 and that is illustrated in detail in FIG. 3. The corner clip 42 includes a base 44 to which an upper wall 46 and spaced bottom walls 48 and 50 are integrally joined. The bottom walls 48 and 50 are spaced apart and thus accommodate the rib 40 of the lock seam formed interiorly of the horizontal frame members 14. Communicating with the space between the walls 48 and 50 is a slot that is formed in the base 44 and that is also adapted to accommodate the lock seam 40. Openings 54 are provided in the walls for receiving bolts therein that are employed for securing the corner clip 42 to the vertical frame members. As seen in FIG. 2 the base 44 of the corner clip 42 engages a vertical surface of the vertical frame member 18 and is disposed interiorly of the horizontal member 14 at the end thereof. Bolts 56 extend through the coextensive bottom walls 32 and 34 of the frame .member 14 and threadably engage the openings 54 formed in the walls 48 and 56 of the corner clip 42. The corner clip 42 is thus firmly secured interiorly of the horizontal frame member 14. As seen in FIG. 2, the rib 40 that defines the lock seam of the frame member 14 is received within the spaces formed between the wall 48 and 50 and further extends through the slot 52 formed in the base 44 of the corner clip 42.

It will be noted that the space defined by the walls 48 and St is somewhat larger than the rib 40, but is constructed in this manner so as to enable the corner clip 42 to be universal in use; that is, it may be reversed in position when located in the horizontal frame member 22. As further shown in FIG. 2 the corner clip 42 cooperates with both the horizontal frame members 14 and 22 to lock these members to the vertical frame member 18. Thus bolts 58 extend through the openings formed in the base 44 of the corner clip 42 and project through spacers 59 for securement to the base of the corner clip located in the opposite horizontal frame member 22. The corner clips 42 in the frame members 22 and 26 are thus, in effect, fixed to each other through the bolts 53 and since the corner clips 42 are secured to their respective horizontal frame members, the horizontal frame members will then be fixed to the vertical frame member 18. It is understood that the horizontal member 14 will be secured to the vertical frame member 16 and to the adjacent horizontal frame member 20 in the manner as just described.

The door assembly 12 which occupies the opening defined by the horizontal frame member 14 and the vertical rail or sash member 60, a lower horizontal sash memframe members 16 and 18 includes an upper horizontal ber 62 spaced from the upper sash member 60 and spaced vertical sash members 64 and 66 that are secured to the horizontal sash members 60 and 62 in the manner that will be described hereinafter. Although not shown, the door assembly 12 is mounted for pivotal movement on the frame by pivot elements that in the present invention would be concealed within the horizontal sash members 60, 62 for securement to the horizontal frame member 14 and to the floor. The door assembly 12 is thus adaptable for use as a center hung type of door, wherein the pivot elements therefor are spaced from the heel edge thereof and the door may be pivotally moved in both an inner and outer direction. It is understood that the door assembly may be pivotally mounted by other conventional hinging such as butt hinges.

As previously described in connection with the horizontal frame member 14, the sash members 60, 62, 64 and 66 that define the door assembly 12 are constructed of a metallic material such as a thin gauge stainless steel and are rolled formed into a tubular configuration as illustrated in FIGS. 5, 6 and 7. Although only the vertical sash member 64 and the horizontal sash member 62 of the door assembly 12 are shown in FIGS. 5 and 6, it will be understood that the vertical sash member 66 and the horizontal sash member 60 are constructed similarly thereto and are rolled to the tubular configuration in a similar manner. The vertical sash member 64 includes a longitudinally extending outer wall 68 that is curved in configuration so as to provide for the double acting pivotal movement of the door assembly 12. Joined to the curved outer wall 68 are side walls 70 and 72 to which inner Walls 74 and 76 are integrally joined. Edges 78 and 80 of the walls 74 and 76 are respectively formed in a lock seam indicated at 81 in the manner as described in connection with FIG. 2, the lock seam 81 being located interiorly of the member 64 as indicated.

The horizontal sash members 60 and 62 are also formed in a tubular construction and are roll formed to define interlocking lock seams. As more clearly illustrated in FIGS. 6 and 7 the horizontal sash member 62 is shown including side walls 32 and 84 that are reversely bent to form inner opposed Walls 86 and 88, respectively, to which an inner web 96 is integrally joined. Joined to the side walls 82 and 84 and bent at right angles with respect thereto are the upper walls 92 and 94 the ends of which are interlocked in a lock seam indicated at 96. As shown in the drawings all of the tubular members that define the door assembly 12 and the frame assembly 11 of the entrance construction 10 are rolled from a one piece sheet material to the tubular shape and are fixed in the tubular configuration by the interlocking of the edges in a lock seam.

Referring now to FIG. 4 and referring again to FIGS. 5, 6 and 7, a corner clip generally indicated at is illustrated, and as shown is secured to the corners of the horizontal sash members 60 and 62 and the vertical sash members 64 and 66 to lock their members in place in the manner as shown. The corner clip 100 is also formed of a stainless steel material so as to be welded to the thin gauge stainless steel door members and includes a base 102 to which an offset portion 104 is joined for the purpose that will be described hereinafter. Secured to the base 102 and extending perpendicularly with respect thereto is a vertical leg 106, the vertical leg 106 being bent along the lines 108 and 110 as indicated, to form the leg in a generally curved or arcuate configuration. As will be described, this configuration of the leg 106 accommodates the lock seam formed on a vertical sash member of the door assembly. Secured to the vertical leg 106 is a horizontal leg 112 that is also bent along lines as indicated at 114 and 116 to form the leg 112 in a generally curved or arcuate configuration. This configuration of the horizontal leg 112 accommodates the lock seam that is formed interiorly of the horizontal member to which the corner clip 100 is secured.

In order to secure the corner clips 100 interiorly of the door assembly members, weld openings are formed in the walls of the sash members so that weld material may be introduced therein, the weld opening being located so that the weld material will engage the base 102 and legs 106 and 112 of the corner clip 100. Referring again to FIGS. 6 and 7 a plurality of openings 118 are shown being formed in the walls 74 and 76 of the vertical sash member 64. An opening 120 is formed in the wall 94 of the horizontal sash member 62 while an opening 122 is formed in the inner web 90 of the horizontal sash member 62. When the corner clip 100 is placed in position within the horizontal and vertical sash members 62 and 64 the surfaces of the portions thereof that are located opposite the weld openings are adapted to receive weld material therein for securing the corner clip 180 in position. As shown in FIGS. 6 and 7, weld material indicated at 124 is deposited in the openings 118 to secure the vertical leg 106 to the walls 74 and 76 of the vertical sash member 64. The horizontal leg 112 is disposed beneath the lock seam 96 and a weld material 126 deposited in the opening 120 engages portions of the horizontal leg 112 to lock this leg to the adjacent walls 92 and 94 of the horizontal sash member 62.

The base 102 of the corner clip 180 is positioned on the upper surface of the inner web 90 and a weld material 128 is deposited in the opening 122 and thus secures the base 102 to the inner web 90. Additional welds indicated at 130 and 132 secure the base 102 to the wall 74 and 76 of the vertical sash member 64, and secure the olfset portion 104 to the 'wall 68 of the vertical sash member 64.

When the corner clip 180 is secured in place as indicated in FIGS. 5, 6 and 7, the horizontal leg 112 is positioned just below the lock seam 96 of the horizontal sash member 62, the arcuate configuration of the horizontal leg 112 accommodating the lock seam 96 as indicated. Similarly when the vertical leg 106 is located in the position as illustrated in FIG. 6, the arcuate configuration thereof accommodates the lock seam of the vertical sash member 64. It is seen that the oifset portion 104 of the corner clip 100 in the assembled position thereof is substantially level with the lower surface of the inner web 90 and thus cooperates therewith to receive a block or assembly that may be inserted within the horizontal sash member 62 from the underside thereof. Such a block or assembly may include a pivot assembly or a closure construction.

The door assembly 12 also includes a glass panel 134 that is adapted to be secured between the horizontal sash members 60, 62 and the vertical sash members 64 and 66. In order to provide for different thickness panels and to further firmly secure the panel 134 in place the present invention incorporates a unique retainer clip as shown in FIGS. 5A, 6A, 8 and 9. Each of the members that define the door assembly 12 has attached thereto a plurality of retainer clips generally indicated at 136, the retainer clips 136 being located in spaced relation and cooperating with appropriate panel retainers indicated at 138 and 140 for securing the panel 134 in position. Although only a single member is described in connection with the retainer clip 136 and although only panel retainers 138 and 140 are referred to it will be understood that the other door assembly members are provided with similar retainer clips and panel retainers.

Referring now to FIG. 9, the retainer clip 136 is shown in detail and includes a first portion 138 that is defined by a central section 140, to which opposed legs are joined, the opposed legs being defined by inclined sections 141, 143, horizontal sections 142, 144 and elevated end sections 146, 148.

integrally joined to the end sections 142, 144 of the opposed legs are depending fingers 150, 152 which, as will be described, are provided for engaging opposing hook portions formed on the panel retainers 138 and 140, wherein the panel retainers are secured to the retainer clips 136.

Joined to the first portion 138 by a central web 154 is a second portion 156 that is constructed substantially identical to the first portion 138 but that is offset with respect thereto. Thus the second portion 156 of the retainer clip 136 includes a central section 158 to which opposed legs are joined. Defining the opposed legs are inclined sections 159, 161, horizontal sections 160, 162 and elevated end sections 164, 166 to which depending fingers 168, 170 are joined. As previously mentioned, the second portion 156 is offset with respect to the first portion 138, thus the finger 170 extends somewhat outwardly of the finger 152 and similarly, the finger eX- tends somewhat outwardly of the finger 168.. The fingers of the first and second portion 138 and 156 are movable with a spring action with respect to the central sections 140 and 158 respectively, this spring movement of the fingers being emphasized by the securement of the retainer clip 136 to the door assembly members by spot welding the central sections 140 and 158 to the eX- posed surfaces of the members on which the panel 134 is mounted. Thus, as seen in FIG. 8, the retainer clip 136 is secured to the member indicated at 62 by welding the central sections 140 and 158 directly to the wall 94. Since the fingers of the first and second portions of the retainer clips are unconnected and are somewhat elevated, they have a certain amount of resilience, which is further emphasized by forming the clips of a thin and relatively hard stainless steel material. The clips 136 are located in spaced relation along the length of each sash member so that the fingers 152 and 168 define an inner position for the panel retainers 138 and 140 that are adapted to be mounted thereon. Conversely the fingers 150 and 170 that extend outwardly beyond fingers 168 and 152, respectively, define an outer position for the panel retainers 138 and 140.

As further seen in FIG. 8 the panel retainers 138 and 140 are formed in a configuration that generally defines a C-shape and include portions 172 and 174 respectively that define grooves into which resilient sealing members 176 and 178 are inserted. Joined to the panel retainers 138 and 140 are spaced from the portions 172, 174 are inwardly extending hook portions 182 and 184 that are adapted to be engaged by the fingers of the retainer clip 136. The panel retainers 138 and 140 are adapted to be inserted in place by the shifting thereof in a lateral direction. The panel retainers are thus located in a first position wherein the hook portions 182, 184 formed on the panel retainers engage the outermost fingers 150, 170 of the retainer clips 136. Thus the finger 150 of the retainer clips 136 will initially engage the hook portion 184 of the panel retainer 140 and similarly the finger 170 will initially engage the hook portion 182 of the panel retainer 138. Since the fingers 152, 163 have a certain amount of resilience, they will be flexed upwardly as they ride on the outer surfaces of the hook portions 182, 184 in this initial position of the panel retainers 138, 140. The glazing or panel 134 is retained between the sealing elements 17? and 18d, and is mounted on a plurality of wood glazing blocks 186 that are located along the length of the sash member 62. If the thickness of the panel 134, is such that additional adjustment is required, then either the panel retainer 138 or 140 may be shifted laterally to force the hook portions 182, 184 thereof to move into engagement with the fingers 152, 168 of the retainer clip 136. As seen in FIG. 8 the inner fingers 152 and 168 are shown riding on the outer surface of the hook portions 182 and 184 respectively. Upon inner lateral movement of the panel retainer 138, for example, the finger 152 will be moved into engagement with the hook portion 182, the engaged finger 1'70 accommodating this movement because of the resiliency of the leg to which the finger is secured. Similarly if it is required to shift the panel retainer 140 inwardly for adjustment thereof, the inner finger 168 will ride off of the upper surface of the hook portion 184 and into engagement therewith. It is understood that the outer finger 150 will accommodate this action due to the resiliency thereof.

It is seen that the retainer clips 136 provide a unique manner of adjustably securing the panel retainers 138 and 140 on the various members that define the door assembly 12. It is also understood that the panels 24 of the frame assembly 11 may also be secured to the frame members indicated at 14, 18, 20 and 22 by incorporating the retainer clips 136 as previously described. Since the material from which the door assembly members are constructed is preferably stainless steel, the retainer clips 136 may be welded directly to the surfaces of these members. However, if it is desired the retainer clips may be mounted in place by the use of screws that extend through openings formed in the central sections 146 and 158 thereof.

While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except inso far as indicated by the scope of the appended claims.
