[0034] In an embodiment, a fire-rated component 110, 112, 114 for access control hardware 100 is provided. Fire-rated component 110, 112, 114 includes a body 130, 230 defining a receptacle 134, 234 for housing a lockset component 102. Body 130, 230 includes a plate portion 132, 232 defining at least one passage 120, 122, 220, 222 for receiving threaded fastener 116, 118. Plate portion 132, 232 includes a first retention flange 150, 154, 250, 254 extending around a first portion of the at least one passage 120, 122, 220, 222 and a second retention flange 152, 156, 252, 256 extending around a second portion of the at least one passage 120, 122, 220, 222. First retention flange 150, 154, 250, 254 and second retention flange 152, 156, 252, 256 are circumferentially spaced from one another.

[0035] In an embodiment, a fire-rated component 110, 300 for access control hardware 100 is provide. The fire-rated component 110, 300 includes a blocking body 304 comprised of first resistant material. The blocking body 304 defines a receiving passage 306 for receiving an elongated lockset component, such as a tailpiece or drive bar 302 passing through blocking body 304. The blocking body 304 includes a first pivotable tab 308 on one side of receiving passage 306 and a second pivotable tab 310 on another side of receiving passage 306. The first and second pivotable tabs 308, 310 engage the lockset component 302 while pivoting away from one another to allow passage of the lockset component therebetween.

[0036] Referring to FIGS. 3-4, further details of fire-rated component 110 in the form of fire cup 112 will be described. Fire cup 112 includes body 130 defining receptacle 134 that is configured to receive one or more lockset components 102. For example, in an embodiment, lockset component 102 includes body 230 of latch 114, and a portion of body 230 is positioned in receptacle 134, such as shown in FIG. 5.

[0037] Body 130 includes plate portion 132 extending along one side of receptacle 134. Body 130 also includes upper and lower legs 136, 138 extending transversely to plate portion 132 along upper and lower sides of receptacle 134. Each of the upper and lower legs 136, 138 includes corresponding one of a semi-circular abutment portion 140, 142 extending transversely thereto and parallel to plate portion 132. Each of upper and lower legs 136, 138 also includes a corresponding one of retaining tabs 144, 146 extending along receptacle 134 parallel to plate portion 132 on the opposite side of receptacle 134.

[0038] Plate portion 132 may also include a hole 148 for passage of a lockset component 102 transversely therethrough, such as a lock cylinder tailpiece. Embodiments without hole 148 are also contemplated. Plate portion also includes first passage 120 and second passage 122 for receiving respective ones of the threaded fasteners 116, 118. Plate portion 132 includes first and second retention flanges 150, 152 extending partially around first passage 120. Plate portion 132 also includes third and fourth retention flanges 154, 156 extending partially around second passage 122.

[0039] First retention flange 150 extends circumferentially around first passage 120 between opposite ends 160, 162 of first retention flange 150. Second retention flange 152 extends circumferentially around second passage 122 between opposite ends 164, 166 of second retention flange 152. Ends 160, 164 are spaced from one another and separated by a first gap 168. Ends 162, 166 are also spaced from one another and separated by a second gap 170. Since the retention flanges 150, 152 do not occupy all, or extend completely around, the entire perimeter of first passage 120, first fastener 116 can be threaded through first passage 120 without being unduly hindered by retention flanges 150, 152. However, retention flanges 150, 152 are configured to project into the thread profile of first fastener 116 to capture the first fastener 116 on fire cup 112.

[0040] As shown in FIG. 4, first passage 120 extends along a longitudinal axis L, which corresponds to a direction along which first fastener 116, extends when installed. First and second flanges 150, 152 are obliquely oriented to plate portion 132, and project outwardly from a side of plate portion 132 that is opposite receptacle 134 by a first distance D1. First and second flanges 150, 152 extend to corresponding end surfaces 170, 172 of each of the first and second flanges 150, 152. Ends surfaces 170, 174 are also obliquely oriented to longitudinal axis L1, such as angles A1, to facilitate passage of threaded fastener 116 between flanges 150, 152.

[0041] Second passage 122 and its retention flanges 154, 156 can be similarly configured to first passage 120 and retention flanges 150, 152. In an embodiment, retention flanges 150, 152, 154, 156 are formed by cutting and stamping plate portion 132. However, other fabrication techniques are also contemplated.

[0042] Referring further to FIG. 5, retaining tabs 144, 146 work in conjunction with plate portion 132 to receive and maintain the portion of lockset component 102 received in receptacle 134 in position. For example, fire cup 112 is first positioned in cross-bore 80 during assembly of access control hardware 100. Latch 114 is then installed with a portion of body 230 positioned in receptacle 134 of fire cup 112. Latch 114 is this retained in a provisional position and orientation with fire cup 112 during the initial installation steps. Threaded fasteners 116, 118 are then installed into bores of interior trim 106, through respective ones of first and second passages 120, 122 and aligned holes of lockset component 102, and into threaded blind bores 190 of exterior trim 104, such as shown in FIG. 7.

[0043] In an embodiment, exterior trim 104 includes an exterior back plate 180, and interior trim 106 includes an interior back plate 182. Back plates 180, 182 are typically provided for structural support of the trim and are made from steel or other fire-resistant material. Threaded fasteners 116, 118 also pass through back plates 180, 182 in order to secure access control hardware 100 to door 70. If the non-fire rated components of exterior trim 104 melt away such that fasteners are no longer engaged in the bores 190, the fire cup 112 and/or other component with retaining flanges around the passages thereof remain engaged to threaded fasteners 116, 118 such as shown in FIG. 6. This retention of the fire-rated component 110 allows the threaded fasteners 116, 118 to maintain the positioning of exterior back plate 180 and/or interior back plate 182 during a fire.

[0044] Referring to FIGS. 8-9, and example of a latch 114 that is configured as a fire-rated component is provided. Latch 114 includes a tubular or sleeve shaped body 230 defining receptacle 234 for receiving one or more lockset components 102 that are latch-related components. Body 230 includes plate portion 232 along at least one side of receptacle 234. Plate portion 232 includes first and second passages 220, 222 for receiving respective ones of the first and second threaded fasteners 116, 118. First passage 220 includes first and second retention flanges 250, 252, and second passage 222 includes third and fourth retention flanges 254, 256. Retention flanges 250, 252, 254, 256 can be configured similar to, or identically to, the flanges 150, 152 discussed above for passage 120.

[0045] In the illustrated embodiment, plate portion 232 is located on the side of body 230 facing away from interior trim 106. Additionally or alternative, the plate portion 236 of body 230 facing interior trim 106 may include retention flanges around passages for the threaded fasteners similar to plate portion 232. In a further embodiment, only one retention flange is provided around a portion of each passage through plate portion 232, and only one retention flange is provided around a portion of each passage through plate portion 236.

[0046] Referring to FIGS. 10-12, another embodiment fire-rated component 110 is illustrated in the form of blocker 300. Blocker 300 can be mounted on an elongated component of lockset components 102 located in cross-bore 80, such as a tailpiece or drive bar 302 of a lock cylinder. Blocker 300 can be used alone, or in conjunction with one or more other fire rated components 110 such as fire cup 112 and/or latch 114 discussed above.

[0047] Blocker 302 includes blocking body 304 comprised of first resistant material. In an embodiment, blocker 302 is fabricated from spring steel. The blocking body 304 defines receiving passage 306 for receiving a lockset component such as drive bar 302 passing through blocking body 304. Blocking body 304 includes first pivotable tab 308 on one side of receiving passage 306 and second pivotable tab 310 on another, opposite side of receiving passage 306. The first and second pivotable tabs 308, 310 engage the driver bar 302 while pivoting away from one another to allow passage of the driver bar 302 therebetween.

[0048] In the illustrated embodiment, blocking body 304 is a flat plat-like disc with a circular shaped outer perimeter 312 extending between opposite flat side surfaces 322, 324. Perimeter 312 includes opposite notches 314, 316 to facilitate insertion, orienting, and/or retention of blocker 300. Other embodiments contemplate non-circular shapes of outer perimeter 312. First tab 308 includes a first hinged connection 318 with blocking body 304, and second tab 310 includes a second hinged connection 320 with blocking body 304. In the illustrate embodiment, first and second hinged connections 318, 320 are living hinges. Other embodiments contemplate other connections between tabs 308, 310 and plate body 304.

[0049] First and second hinged connections 318, 320 orient first and second tabs 308, 310 to extend obliquely and outward from first side surface 322 as shown in FIG. 12. This allows first and second tabs 308, 310 to flex or pivot further outwardly from first side surface 322 relative to blocking body 304 to allow driver bar 302 to pass therebetween, but maintain engagement of first and second tabs 308, 310 against the opposite sides of driver bar 302, as shown in FIGS. 13 and 17. In the illustrated embodiment, first and second tabs 308, 310 are rectangularly shaped, providing linear outer edges that maximize contact drive bar 302. Other embodiments contemplate other configurations for first and second tabs 308, 310.

[0050] In an embodiment, during mounting of access control hardware 100 to door 70, blocker 300 is manually positioned over drive bar 302 and slid therealong into contact with, or in adjacent position to, plate portion 132 of fire cup 112 as shown in Fig, 13. This provides a temporary hold of the exterior trim 104 on the lockset components in cross-bore 80 until fasteners 116, 118 are installed to engage interior trim 106 to exterior trim 104 through the lockset components 102 as shown in FIG. 14. Blocker 300 thus serves as an installation aid in addition to blocking passage of light and flames through cross-bore 80 along drive bore 302. In addition, the grip of blocker 300 on drive bar 302 can prevent blocker 300 from being ejected off of drive bar 302 when a hose stream is applied to lockset components 102.

[0051] Referring to FIGS. 15-16, lockset components 102 are shown in cross-bore 80 od door 70 without blocker 300.
