Abstract
A locking system includes a lockcase which can be embedded within a recess in a jamb of a doorway. A barn door mounted outside of the doorway can be locked in the closed position by actuation of a lock mechanism within the lockcase. The handle interacts with the lockcase, causing a bolt to be translated out of the lockcase and into a strike in the barn door. The strike preferably passes entirely through the barn door, the strike including an outer entry which can be accessed via a key to push back the bolt and defeat the lock for emergency access. Cover plates and handles of different types can be provided for optimal performance. Lock mechanisms within the lockcase convert handle actuation into bolt translation between a collapsed orientation and a deployed orientation for locking the barn door.

DESCRIPTION OF THE PREFERRED EMBODIMENT
(18) Referring to the drawings, wherein like reference numerals represent like parts throughout the various drawing figures, reference numeral 10, 110 is directed to a lockset (
(19) In essence, and with particular reference to
(20) A handle 40 is coupled to the lockcase 50, so that when the handle 40 is actuated, such as by rotation (along arrow A of
(21) A strike 80 is also preferably provided as part of the system of this invention for use with the lockset 10. The strike 80 provides, at a minimum, a hole passing into the barn door D at an appropriate location so that when the bolt 70 moves to its deployed orientation it extends into the strike 80. The strike 80 most preferably passes entirely through the barn door D and includes an outer entry through which a key 200 or other structure can be placed to push back the bolt 70 away from its deployed orientation and out of the strike 80, and so that emergency access can be gained through the barn door D in the doorway passage P.
(22) More specifically, and with particular reference to
(23) The baseplate 20 is preferably a rigid monolithic structure, typically formed of a machinable metal, but conceivably formable from casting or injection molded (such as from plastic), or formed of wood, metal or other materials, either molded or machined or otherwise formed. The baseplate 20 includes a flange 22 which preferably resides adjacent to the face F and in a plane parallel with a longest dimension of the lockcase of the jamb J. The flange 22 preferably includes holes which receive frame screws 23 which pass through the holes in the flange 22 and then embed into material of the face F of the jamb J adjacent to the recess into which the lockset 10 is placed.
(24) The baseplate 20 includes a collar 24 extending inwardly from the flange 22 to a floor 26. The floor 26 is preferably planar in form and parallel with the flange end perpendicular to the collar. Mount screws 25 pass through holes in the floor 26 and thread into standoffs 27 or other portions of the lockcase 50 to secure the baseplate 20 to the lockcase 50. Thus, the base plate 20 is held in position relative to the jamb J by the frame screws 23 and the base plate 20 holds the lockcase 50 to the baseplate 20 through the mount screws 25.
(25) Preferably standoffs are provided associated with these mount holes so that the mount screws can either thread into the standoffs rather than into the mount holes directly, or the standoffs can merely act as alignment structures with the mount screws sufficiently long that they pass through the standoffs and into the mount holes of the lockcase for threadable attachment. In one embodiment, the standoffs are two part standoffs with a central cylinder and an outer cylinder for each of the standoffs. The central cylinders have a smaller diameter and are pressfit into the body and extending perpendicularly away from the body and toward the base plate. The outer cylinder standoff portions fit over the central cylinder standoff portions for alignment of the base plate with the body. Then, the mount screws pass through or into the standoffs and threadably attach the base plate securely to the body of the lockcase. In embodiments shown, the standoffs are female threaded elongate cylindrical structures held to the body by fastening to the body or by action of the mount screws passing through the floor of the base plate and into the standoffs, so that the standoffs are configured as she bolts.
(26) A hole 28 is formed in the center of the floor 26 which allows portions of the handle 40 to pass through the baseplate 20 and engage with a lock mechanism within the lockcase 54, for actuation of the lockset 10 and movement of the bolt 70 between its retracted orientation and its deployed orientation. The collar 24 is a cylindrical ring shaped structure defining a depth by which the floor 26 is spaced from the flange 22, with the floor 26 preferably parallel with the flange 22. The collar 24 in this embodiment also includes female threads thereon which allow for attachment of the cover plate 30 (described below) to the baseplate 20 without requiring separate fasteners. However, the cover plate 30 could be attached to the base plate 20 by other means, or the cover plate 30 could be dispensed with entirely.
(27) In this embodiment, the cover plate 30 includes an annular shoulder 32 which overlies the flange 22 of the baseplate 20. Inboard of the shoulder 32, a ring 34 extends cylindrically and generally perpendicular to the shoulder 32. A shroud 36 surface is located on an inboard end of the ring 34 opposite the shoulder 32, with the shroud 36 preferably parallel with the shoulder 32. An outer surface of the ring 34 preferably includes male threads thereon which match the female threads on the collar 24. Thus, the ring 30 can thread into the collar 24 so the cover plate 30 attaches to the baseplate 20. A hole passes through a center of the shroud 36 of the cover plate 30, which is aligned with the hole 28 in the baseplate 20 and facilitates portions of the handle 40 passing through the cover plate 30 for engagement with the lock mechanism within the lockcase 50 and for actuation of the bolt 70.
(28) In this embodiment, the handle 40 is configured to be a recessed handle. In other embodiments this recessed handle 40 is replaced with a handle 140 (
(29) The shaft 44 is preferably linear and extends along a rotational axis centerline. The shaft 44 preferably includes facets 46 thereon which can assist in having the shaft 44 of the handle 40 engage with a lock mechanism within the lockcase 50. Alternatively, the shaft 44 can be otherwise affixed to structures within the lockcase 50. In this preferred embodiment, the shaft has a square cross-section with four flat faceted sides making up the facets 46. While the handle 40 of this preferred embodiment is shown as a rotating handle which causes the shaft 44 to rotate, it is conceivable that the handle 40 could be replaced with a slide handle which would merely be slid (such as toward or away from the barn door D), and with such a slide handle having a shaft which does not rotate, but rather a shaft that translates linearly (at least somewhat) and with a portion of such a translating shaft most distant from such a sliding handle engaging with the bolt 70 to move the bolt 70 between its retracted and deployed orientations.
(30) With particular reference to
(31) The lockcase 50 can have any of a variety of interior configurations to cause rotating motion of the shaft 44 of the handle 40 (arrow A of
(32) The bolt 70 is a rigid structure of hard material, typically steel, which is caused to translate linearly from a deployed orientation to a retracted orientation, and vice versa, by action of the lock mechanism within the lockcase 50, which is actuated by the handle 40. The bolt 70 can include an optional extension 72 with a threaded post 74 which threads into a threaded hole at an end of the bolt 70 (or vice versa). Such an extension 72 can be added if needed to accommodate thicker jambs J with a greater distance to an exterior E of the jamb J. Similarly, the extension 72 on the bolt 70 can be provided if a larger than typical gap exists between the barn door D and the wall W. The extensions can be rotated to provide adjustable bolt length as well. The bolt 70 could have any of a variety of different cross-sectional shapes. In this embodiment, the bolt is shown with a circular cross-section and a cylindrical form having a constant cross-section along its length. Such a contour for the bolt 70 allows it to easily pass into a cylindrical central bore within the strike 80.
(33) The strike 80 could in a simplest form of the invention merely be a hole formed in the barn door D. Most typically, this hole would be cylindrical and having a circular cross-section, similar to a size of the bolt 70, but typically slightly larger so that alignment of this hole with the bolt 70 can be accommodated. Most preferably, the strike 80 is provided as a hardened structure which supplies this hole for the bolt 70. The strike 80 at a minimum is a bore extending into an inside of the barn door D. Most preferably this bore passes entirely through the barn door D and out to the outside of the barn door D, so that the bore is in the form of a through bore. In the most preferred embodiment for this strike 80, an outer sleeve 82 and inner sleeve 84 are provided which threadably attach together and define this through bore passing through the barn door D when the sleeves 82, 83 are attached together. Lips 83, 85 on the sleeves 82, 84 act as stops which abut the outside O and inside I of the barn door D after the sleeves 82, 84 have been fully threaded together. In one embodiment, these sleeves 82, 84 have a substantially constant circular cross-section, but can be tapered slightly near the lips 83, 85, and in particular adjacent to the lip 85 on the inner sleeve 84. Such a taper can cause a diameter of the door to be slightly greater at the lip 85, and help to align the bolt 70 with the strike 80, especially if the strike 80 is slightly out of alignment with the bolt 70. In one embodiment, the through bore is not circular cross-section but is taller than it is wide, so that the strike 80 can be more easily placed without requiring precise vertical positioning relative to the bolt 70, but still providing a tight lock on the bolt 70 in its deployed orientation extending into the strike 80 (to resist door opening motion, such as along arrow C of
(34) With particular reference to
(35) While the barn door D could be carried in a variety of different ways, most typically hangers H (
(36) Typically the barn door D is on an exterior of a room where privacy is desired and outside of where the handle 140 (for the privacy lock associated with the lockset 110) is located. Typically, a basic pull is attached to the barn door D (on the inside I, outside O or both), so that the barn door D can be most easily slid upon the rail R (along arrow C of
(37) A bracket 120 (
(38) Mount bores receive mount screws 125 which also pass through mount holes 132 in an annular cover plate 130 to allow the annular cover plate 130 to be securely attached to the bracket 120. A slot 126 is provided between the front wall 122 and rear wall 123 of the bracket 120. This slot 126 is sized to receive a lockcase 150 therein extending in a lateral direction generally perpendicular to surfaces of the front wall 122 and rear wall 123, so that the lockcase 150 can be securely held relative to the bracket 120. The bracket 120 would typically be placed into the recess in the jamb J by passing through the face F of the jamb J, while the lockcase 150 would extend through the exterior E (
(39) The annular cover plate 130 is similar in many respects to the cover plate 30, and with screw holes 132 passing therethrough which allows the mount screws 125 to pass through the screw holes 132 and then into the mount screws 125 for the bracket 120. The mount screws 125 can be tightened to removably secure the cover plate 130 to the bracket 120. The cover plate 130 is preferably substantially flat and facilitates a handle 140 which is disabled accessible (or, as an alternative, a recessed handle 240 (
(40) The lockcase 150 preferably includes a body 160 which contains at least portions of the lockcase 150 therein. The bolt 170 portion of the lockset 110 is preferably contained within a barrel core 152 and barrel cover 153 which also form portions of the lockcase 150. The body 160 includes port 162 which can receive the shaft 145 of the handle 140 passing into an interior of the lockcase 150. A pair of housing plates 164 on opposite sides of the body 160 encapsulate the lock mechanism within the lockcase 150 with the port 160 passing into (or through) the housing plates 164.
(41) In this particular embodiment of the lock mechanism of the lockcase 150, a hub 165 is located within the body 160 and adjacent to the port 162 which has a bore 166 passing therethrough (or just thereinto) which can receive the shaft 144 of the handle 140 therein. This bore 166 has facets which accommodate facets on the shaft 144 so that when the handle 140 rotates, the hub 165 is caused to rotate along with the shaft 144 and handle 140 (along arrow A).
(42) The hub 165 preferably has a cam surface 167 on outer portions thereof. This cam surface 167 interacts with a leaf spring 169 adjacent to the hub 165, so that when prominences on the cam surface 167 pass the spring 169, some resistance to hub 165 rotation is encountered, and when low portions of the cam surface 167 are adjacent to the spring 169, little or no resistance to hub 165 rotation is encountered.
(43) Furthermore, the hub 165 includes a finger 168 extending radially therefrom. The finger 168 passes through a pocket 178 in an arm 174 which is coupled to the bolt 170. When the hub 165 rotates, the finger 168 also rotates (arrow A) and, residing within this pocket 178, causes the arm 174 to translate (arrow B), and to translate the bolt 170 linearly along a central axis of the bolt 170. A proximal tip 172 of the bolt 170 preferably is recessed in size and resides within a seat 175 in a distal end of the arm 174. A setscrew 176 joins the proximal tip 172 of the bolt 170 to the arm 174. Bolts 170 having different lengths can be selected so that the bolt 170 travel distance is in an amount desired. Alternatively, or in addition, the barrel core 152 and barrel cover 153 can be threadably attached together at various different positions amounts to alter a length of the combined barrel core 152 and barrel cover 153 and to further allow for adjusting of the position of the bolt 170. An annular flange on the barrel cover 153 typically resides against the exterior E of the jamb J and helps to securely hold the lockcase 150 and associated bolt 170 precisely and solidly where desired.
(44) Most preferably in this embodiment, strike assembly 180 is provided within the barn door D for receipt of the bolt 170 when it is in its deployed orientation. The strike assembly 180 includes a hollow cylinder 182 with an annular flare 183 on an inner portion thereof adjacent to an inside I of a barn door D (or spaced away by a spacer 197). An outer cap 184 preferably attaches to the cylinder 182 (through intermediate structures) and is adjacent to the outside O of the barn door D. A shaft 185 preferably threadably attaches to the outer cap 184 through threads on a head 187 or nut 196 of the shaft 185 which cooperate with threads on an interior of the outer cap 184 to hold the head 187 to the cap. A spring 190 is interposed between a dust cap 192 and a base 194 (to which the shaft 185 can threadably attach in a central collared hole therein), with the base 194 adjacent to the shaft 185 and the dust cap 192 adjacent to the barrel core 152 and barrel cover 153 of the lockcase 150. Spring 190 causes the dust cap 192 to close off the cylinder 182 within the strike assembly 180. However, when the bolt 170 strikes the dust cap 192, the spring 190 is compressed and the bolt 170 is allowed to pass into the cylinder 182. A key 200 or other elongate structure can pass into the shaft through the outer cap 184 and pass through a central hole in the bolt 185 and abut against the dust cap 192 to push the bolt 170 from its deployed orientation back toward its retracted orientation, such as for emergency access through the doorway passage P after the door D has been opened by sliding (along arrow C).
(45) This disclosure is provided to reveal a preferred embodiment of the invention and a best mode for practicing the invention. Having thus described the invention in this way, it should be apparent that various different modifications can be made to the preferred embodiment without departing from the scope and spirit of this invention disclosure. When structures are identified as a means to perform a function, the identification is intended to include all structures which can perform the function specified.
