DETAILED DESCRIPTION
The exemplary embodiments of the present invention are described and illustrated below to at least include methods of engaging and disengaging latches for repositionable and expandable gates, as well as devices to selectively couple gate doors to gate frames. Of course, it will be apparent to those of ordinary skill in the art that the preferred embodiments discussed below are exemplary in nature and may be reconfigured without departing from the scope and spirit of the present invention. However, for clarity and precision, the exemplary embodiments as discussed below may include optional steps, methods, and features that one of ordinary skill should recognize as not being a requisite to fall within the scope of the present invention.
Referencing FIG. 1, an exemplary embodiment of the present invention includes a repositionable gate 100 for spanning across openings to inhibit egress though such openings. Uses for repositionable gates 100 of this type may include spanning doorways and stairwells to inhibit egress of children and pets that might be injured or themselves cause damage if allowed to egress into certain areas. In exemplary form, the gate is positioned to span a doorway so that the ends 102, 104 of the gate frame 106 abut the doorway on opposing sides. An expandable swinging door 108, comprising a first gate segment 110 slidably mounted to a second gate segment 112, is mounted to the gate frame 106 on one end 104 using hinges 114 that allow the door to be open and closed. In this exemplary embodiment, the gate door 108 is repositionable from its barrier position (shown in FIG. 1) to an open position on the inbound side 116 of the doorway or to an open position on the outbound side 118 of the doorway (separated by an imaginary plane shown as a dotted line in FIG. 1).
Referring to FIG. 1, the repositionable gate 100 includes a gate latch 120 to maintain the gate door 108 in its barrier position. The exemplary gate latch 120 includes a dual action mechanism that requires two distinct movements to disengage the latch 120 before the door 108 is free to be swung to either the inbound side 116 and the outbound side 118 of the doorway. The latch 120 includes a latch handle assembly 122 mounted to a top corner of the second gate segment 112 opposite the hinges 114, and a latch catch assembly 124 mounted to a top portion of the gate frame 106 on a corresponding end 102 opposite the latch handle assembly.
Referencing to FIGS. 2 and 3, the exemplary latch catch assembly 124 includes complementary left and right side housings 126, 128 cooperating to define a cavity 130 accommodating longitudinal travel of an indicator pin 132. A spring 134 is partially housed within a cylindrical pocket 136 of the pin 132 and is operative to bias the pin in its forwardmost position. In its forward most position, a front rectangular face 138 of the pin 132 is adjacent to a front face 140 on the inside of the housings that defines the cavity 130. A colored indicator 142 on the side of the pin 132 includes two rectangular colored blocks 144, 146 (each colored differently), with one of the colored blocks being visible through an opening 148 in the right side housing 128. As will be discussed in more detail later, a dowel 150 of the latch handle assembly 124 contacts a forward portion 152 of the pin 132 when the gate door 108 is in its barrier position. When the door 108 is in its barrier position, the bias of the spring 134 is overcome by the bias of the dowel 150 and secures the dowel within a forward recess 154 of the latch catch assembly 124. As the bias of the spring 134 is being overcome by insertion of the dowel 150, the pin 132 is moved rearward so that the first colored block 146 is no longer visible though the opening 148, but rather the second colored block 144 is visible, thereby objectively indicating that the door is in its barrier position. Opposing angled faces 156 on the left and right side housings 126, 128 operate to guide the dowel 150 into the recess 154 and concurrently overcome the bias of the dowel causing it to recede prior to insertion into the recess. A series of fastener channels 158 associated with each of the left and right side housings 126, 128 receive fasteners (not shown), such as screws, to mount the housing to one another and sandwich the pin 132 and spring 134 therebetween.
Referring to FIG. 4, the latch handle assembly 122 in exemplary form includes right and left side outer housings 160, 162 that at least partially cover right and left side inner housings 164, 166. Each outer housing 160, 162 includes a plurality of fastener channels 168 that receive a fastener (not shown), such as a screw, to mount the housings to one another. When the outer housings 160, 162 are mounted to one another, a cavity is formed therebetween, which is eventually occupied by the assembled inner housings 164, 166. Two projections 170 extending from the interior of the assembled inner housings 164, 166 likewise extend through corresponding orifices 172 through each of the outer housings 160, 162 to provide an axel upon which the outer housings 160, 162 pivot with respect the inner housings 164, 166. Each inner housing 164, 166 also includes a plurality of fastener channels 174 that receive a fastener (not shown), such as a screw<to mount the housings to one another.
The assembled inner housings 164, 166 define an internal cavity accommodating a latch mechanism 176. In exemplary form, the latch mechanism 176 includes a repositionable pin 178, a pin guide 180, a clutch 182, and a cam 184 that cooperate with a follower 186 mounted to the right outer housing 160 to reposition the pin 178 from an engaged position to a disengaged position (compare FIGS. 13 and 14). Outer housings 160, 162 cooperate to define a frontal opening 185 that circumscribes a smaller opening 187 formed by the inner housings 164, 166 through which the dowel 150 extends. As previously discussed, the outer housings 160, 162 pivot with respect to the inner housings 164, 166 and the larger opening 185 through the outer housings accommodates the vertical traversal of the housings 160, 162 with respect to the dowel 150.
Referring to FIGS. 4-6, the repositionable pin 178 includes a forward dowel 150 having a generally cylindrical cross section that transitions into a domed endpoint 152. A rear aspect 188 of the pin 178 integrally formed with the dowel 150 has a predominantly rectangular cross-section that includes opposed rectangular projections 190 extending from each lateral side. These rectangular projections 190 are seated between parallel raised walls 192 extending from the interior of each of the right and left inner housings 164, 166, which cooperate to form a track within which the pin 178 is repositioned longitudinally. A rear side of the pin 178, opposite the dowel 150, is hollowed out to form a cylindrical cavity (not shown) that receives a spring 194, which is at least partially compressed between the pin 178 and a rear endpoint 196 of the track. A downwardly extending projection 198 of the pin 178 is seated within a longitudinal channel 200 of the pin guide 180 so that when the pin 178 is in its most forward position, the projection 198 abuts a front wall 202 partially defining the channel 200. A pair of longitudinal fins 204, extending from the lateral sides of the pin guide 178, are received within corresponding longitudinal grooves 206 formed within the interior of the complimentary right and left inner housings 164, 166. When the pin guide 180 is repositioned, the fins 204 ride within the grooves 206 to assure that the movement of the pin guide with respect to the inner housings is substantially linear.
As discussed previously, the top of the pin guide 180 includes a channel 200 acting as a guide for the projection 198 of the pin 178. Because the pin 178 and pin guide 180 are not rigidly coupled to one another, independent actuation of the pin 178 toward the rear 208 of the inner housings 164, 166 would longitudinally reposition the projection 198 within the channel 200, while the channel may or may not stay in position. Likewise, if the pin 178 was moved to a position where the spring 194 was maximally compressed against the rear endpoint 196 of the track, the pin guide 180 could be repositioned longitudinally without changing the position of the pin 178 as the pin would remain stationary while the channel 200 was repositioned.
Referring to FIGS. 4-6, 9, and 10, an arrow shaped hitch 210 extends from the rear of the pin guide 180 and interacts with the clutch 182 to selectively link the cam 184 to the pin guide 180. The hitch 210 includes a rearmost tapered head 212 and a pair of recesses 214 each having a distal stop 216 that selectively interacts with one of the biased arms 218, 220 of the clutch 182.
Referencing FIGS. 4 and 7-12, each of the arms 218, 220 of the clutch 182 includes a tapered detent 222 to be received within one of the recesses 214 of the hitch 210 (see FIGS. 5, 6, and 10), where a substantially perpendicular surface 224 of the detent 222 abuts a substantially perpendicular surface of each of the stops 216 when the clutch 182 engages the pin guide 180. To inhibit unwarranted engagement between the arms 218, 220 and the hitch 210, a spring 226 is positioned therebetween and mounted to each of the arms 218, 220 to force the arms away from one another and out of the line of travel of the hitch 210. Each arm 218, 220, opposite the detent 220, includes a cylindrical end 228 that is received within a corresponding cylindrical cavity 230 of the cam 184 in order to mount the arms to the cam. Each cylindrical cavity 230 includes an open top 232 with a vertically oriented opening 234 enabling rotational movement of the arms 218, 220 with respect to the cam 184. It is important to note that the width of the opening 234 is less than the diameter of the cylindrical end 228 to inhibit the end 228 from pulling through the opening 234, while the closed bottom of the cavity 230 inhibits the cylindrical end 228 from vertically passing therethrough. A distal portion of the cam 184 includes a right triangular panel 236 perpendicularly mounted to a platform 238. An exposed surface 240, comprising the hypotenuse of the triangular panel 236, slides upon the exterior cylindrical surface of the follower 186 when the inner housings 164, 166 are pivoted with respect the outer housings 160, 162. Each lateral end 240 of the platform 238 is received within a corresponding groove 242 formed within the right and left inner housings 164, 166, 144 and operate to guides the cam 184 in a longitudinally linear path parallel to the paths of the arms 218, 220 that have their own guides 244 that receive corresponding projections 246 from the inner housings 164, 166.
Referencing FIGS. 1, 9, 12 and 13, repositioning of the door 108 from its barrier position or to its barrier position involves manipulation of the gate latch 120. For purposes of explanation, it is presumed that the repositionable door 108 is in its barrier position and the foregoing explanation will detail how to reposition the door 108 and how the corresponding assemblies 122, 124 are repositioned to carry this out. As discussed previously, a dowel 150 extending from the latch handle assembly 122 is received within a recess 154 of the latch catch assembly 124 to maintain the door 108 in its barrier position.
A user desirous of repositioning the gate door 108 to either the inbound side 116 or the outbound side 118 of the doorway must first engage the clutch 182 by depressing one or both of the buttons 170 that extend through the outer housings 160, 162. Depression of one or both buttons causes an inner surface of the clip 250 to abut the outer surface of at least one of the biased arms 218, 220 and overcome the bias exerted by the spring 226 and reposition at least one of the detents 222 within at least one of the recesses 214 of the hitch 210. While continuing to depress one or both buttons 170 so that at least one of the detents 222 is received by at least one of the recesses 182, the outer housings 160, 162 are pivoted with respect to the inner housings 164, 166 by applying pressure to the top rear 252 of the outer housings. This pivoting motion of the outer housings 160, 162 causes the cam 184 to contact the follower 186 and overcome the bias of the cam spring 253 so that the cam can be displaced rearward, away from the front 254 of the housings. As the cam 184 is moved rearward, the biased arms 218, 220 are likewise moved rearward at the same time and to the same extent as the cam 184. When the biased arms 218, 220 are repositioned rearward, the substantially perpendicular surface 224 of at least one the detent 222 abuts the substantially perpendicular surface of at least one of the stops 216 so that continued rearward movement of the biased arms 218, 220 results in a corresponding rearward movement of the pin guide 180. Continued rearward movement of the cam 184, biased arms 218, 220, and pin guide 180 is operative to secure the detents 222 within the recesses 214 so that further depression of the buttons 170 is unnecessary. In this manner, the user can simply continue pressure on the rearward portion of the outer housings 160, 162 to continue the rearward movement of the cam 184, biased arms 218, 220, and pin guide 180.
When the pin guide 180 is repositioned toward the rear 252 of the inner housings 164, 166, the front wall 202 effectively pulls the pin 178 rearward by the pushing action of the front wall 202 against the pin projection 198 to overcome the bias of the spring 194. This rearward motion of the pin 178 causes the dowel 150 to be withdrawn from the latch recess 154 of the latch catch assembly 124. After the dowel 150 is withdrawn from the latch recess 154, the door 108 may be repositioned by swinging either to the inbound side 116 or the outbound side 118 of the doorway. After the door 108 is repositioned either to the inbound 116 or the outbound side 118 so that the dowel 150 is no longer aligned with the latch recess 154, the pressure upon the top rear 252 of the outer housings 160, 162 may be released, thereby allowing the pin 118 to extend to its static engaged position. It is to be understood, however, that the foregoing sequence should be repeated any time it is desirous to retract the pin 118, such as an instance where one attempts to secure the door 106 in its barrier position.
When the door 108 is in its open or unengaged position, a user simply directs the door 108 toward the barrier position by contacting the domed end 152 of the dowel 150 with one of the angled faces 156 of the latch catch assembly 124. By forcing the dowel 150 against one of the angled faces 156, the force is operative to overcome the bias of the spring 194 and direct the dowel 150 rearward and farther into the inner housings 164, 166. It should be noted that when the pin 178 is traveling rearward, the position of the pin guide 180 may remain stationary. In this manner, movement of the pin 178 with respect to the pin guide 180 is independent because the pin 178 is not rigidly fastened or coupled to the pin guide 180. After the dowel 150 passes beyond one of the angled faces 156, the bias of the spring 194 forces the dowel 150 to extend into the recess 154, where it is retained to maintain the door 108 in the barrier position.
