IN VEN TORS CARL D. GRABER und JAMES M. BRYANT BY 9m@ mt-@ef M ATTORNEYS of the wedge bar between the blocking bar andthe swinging side door frame member is between a generally laterally extending shoulder on the blocking bar rearwardly and laterally outwardly to a generally laterally extending shoulder on the door frame member, so that the wedge bar, when in wedging position between said generally lateral shoulders, resists and prevents rearward movement of the blocking barfrom blocking position between the door and door frame means.l

Still further, preferably common operating means is provided for moving the blocking bar between blocking and non-blocking positions and for moving the wedge bar between wedging and non-wedging positions. Such common operating means is mounted associated with the swinging side door frame member operatively connected to-the blocking bar and wedge bar, so that during locking movement, the blocking bar is first moved from a rearward position forwardly into blocking position in the clearance space between the door and door frame member, after which, continued movement of the operating means then moves the wedge bar from a non-wedging to a wedging position, engaged between the blocking bar and the swinging side door frame member. The operation of the operating means is just reverse for the unlocking movement, that is, first moving the wedge bar to nonwedging position and then moving the blocking bar rearwardly out of the clearance space between the door and door frame member to non-blocking position.

One or more lock means are used to secure the blocking bar in blocking position land the wedge bar in wedging position. Preferably one or more combination locks are used to block movement of the common operating means, to thereby block movement of both of the blocking bar and wedge bar. Further, preferably time lock means is used to preferably directly block movement of the wedge bar, thereby again blocking movement of both the blocking bar and wedge bar.

A iirst embodiment of the vault door construction of the present invention is shown in FlGS. l through 23. First referring to FIGS. l through 4, the construction includes a vault door, generally indicated at dil, hingedly mounted for swinging movement on a vault door frame, generally indicated at 4l, with the door frame 41 in turn being mounted in a vault wall, generally indicated at d2, forming a vestibule opening, generally indicated at 43, through the vault wall 42. The vault door it? and` door frame il are formed rectangular with the vault door having vertical hinged side edge d4, a vertical swinging side edge 45, a horizontal top edge d6, and a horizontal bottom edge 47.

The door 46 is substantially solid with front and rear` generally vertically extending and parallel surfaces 53 and 49. Furthermore, all of the door side, top and bottom edges da through e7 are formed preferably generally perpendicular to the door front and rear surfaces 43 and 49, as shown, thereby forming a swinging side rear corner Sti which is substantially a right angle .corner extending. vertically between the top and bottom edges` 46 and 47.

` The door frame il also has a vertical hinged side edge l, a vertical swinging side edge 52, a horizontal top edge. 53, and a horizontal bottom edge 5d. The door top and bottom edges d6 and i7 extend closely adjacent the door frame top and bottom edges 53 and 54, respectively, when the door di?. is in a` closed position received in the door frame 4i, and the door is mounted for swinging movement on the door frame by the usual top and bottom hinges 55 and 56, the pivot point of which is preferably` forward of the front lsurface 57 of the door frame hinged` side edge Si. Asshown in FG. 7, the top hinge 5S may include the hinge pin 58 mounted on door 49 received in the usual hinge bearing 59 mounted on the door frame il and., as shown in FlGJS, thebottorn hinge S5 may include the usual hinge pin 6i) mounted on the door 46 received in the usual hinge thrust bearing 61? mounted on frame dll.

etween these grooves and ribs will prevent the door hinged side edge 44 from being moved outwardly relative to the frame hinged side edge S1 and this is despite any destruction of the top and bottom hinges 55 and S6. Furthermore, the frame grooves and ribs 64 and 65 are formed substantially the entire front and rear extent of the frame swinging side edge 52 for appearance purposes, so that when the door is swung to its totally open position, as seen in FIG. 4, the hinged side edge 44 of the door and the hinged side edge 51 of the frame will present a continuous alternate ribbed and grooved surface.

The door swinging side edge is formed spaced laterally from the frame swinging side edge 52, as seen, for instance, in FlG. 3, so that although these swinging side edges 45 and 52 extend generally parallel, a generally rectangular opening or clearance space 66 is formed, as seen in FIG. 1l, extending totally from top to bottom of and laterally between these swinging side edges. The forwardmost edge of the door frame swinging side edge 52 is preferably formed with a laterally extending proiection 67 extending laterally a short distance into the clearance space 66 and preferably from top to bottom of this clearance space, as seen in FIG. 3, and for purpose to be hereinafter described.

A vertically extending and generally rectangular cross section blocking bar et; is mounted forwardly and rearwardly movable into and vout of the clearance space 66, again preferably extending completely from top to bottorn of the door and frame swinging side edges i5 and 52, so that when the blocking bar 63 is in forward position, as shown in FG. 3, this blocking bar substantially totally fills the clearance space 66. A mating notch 69 is formed at the forwardmost edge of the blocking bar d8 at the side adjacent the frame swinging side edge 52 for receiving the projection i7 of this frame swinging side edge when blocking bar 68 is at its forwardmost blocking position between the door and frame swinging side edges 45 and 52.

The mating of this projection 67 and notch 69 forms a stop for the blocking bar d@ in the forwardmovernent of this blocking bar into full blocking position, and when the`blocking bar is in blocking position, it is preferred that the front surface 7d of the blocking bar is substantially laterally aligned with the front surface 71 of the frame swinging side edge 52. Furthermore, as shown in FGS. 1 and 3, a lateral offset 72 is formed at the door swinging side edge d5 extending from the door front surface i8 rearwardly a short distance and from top to bottom of the door.

Still further, this offset 72 extends laterally completely covering the blocking bar front surface 7d, the frame TheA door hinged side edge d4 is formed with generally vertically extending alternate grooves and ribs 62 and e3 which mate with similar grooves and ribs 64 and 65 formed 'm the frame hinged side edge 5l when the door is swung to closed position received in the door frame. Thus, when door dil is in closed position received in frame di, the interlocking or interengagement swinging side edge front surface 7l, and` projecting laterally a slight distance from the frame swinging side edge 52 when the door iii is in closed position and the blocking bar 68 is in blocking position, as shown in FlG. 3. Also,` the vault wall front surface 73 is spaced rearwardly or inset from both the front surface 7l ofthe frame swinging side edge 52 and this offset 72, so that a handle 74 may be mounted on the free vertical' edge of this offset projecting laterally spaced forwardly of the` vault wall front surface 73 easily accessible for` swingingly moving the door 4t? between open and closed positions. i

As indicated by hidden lines in FG. l, a part of the door at the front surface d3 may be also formed to slightly overlap both the door frame top edge 53 and bottom edge 54 so that, if desired, a hydraulic seal of usual construction (notV shown) may be provided. between the door 4d and door frame 4l along the door frame top and bottom edges 53 and54, as well as between the door offset 72 and the front surface 71 of the frame swinging side edge 52. Further, such hydraulic seal may also be installed at the. door hinged side edge 44 between certain of the door grooves and ribs 62 and 63 and the door frame grooves` and ribs 6d and 65.

Spring-urged door latch 75 is operably mounted in the control knob 77 extending forwardly of the vault wallk front surface 73.

Further, the latch 75 is received laterally in a slot 78 formed in a latch engagement plate 79, which plate is mounted on andl extends rearwardly from the door offset 72. The latch engagement plate 79 is received in a rear-V wardly extending slot 80 in the frame swinging side edge 52, as shown, with the latch 75 normally being springurged toward slot 80 and into engagement with the latch engagement plate 79, and being selectively movable laterally away from or out of such engagement through the gear rack arrangement 76 and control knob 77.

When the door 40 is swung from open position toward closedfposition, the latch 75 will not automatically engage in the slot 78 of the latch engagement plate 79, but rather the rear surface 81 of latch engagement plate 79 will engage the forward surface 82 of latch 75, thereby stopping the door slightly offset from completely closed position and preventing injury to an operators fingers that might be positioned between the door offset '72 and the front surface 71 of the frame swinging side edge 52. The operator must then retract the latch 73 by rotating the control knob 77 while urging the door 40 fully closed to permit the latch engagement plate 79 to be received fully rearwardly into the slot 80111 the frame swinging side edge 52, after which the latch 7S may be released to be spring-urged into engagement in the slot 78 of the latch engagement plate 79 for retaining the door 40 in fully closed position.

Referring to FIGS. 2, 3, ll through 17, 20, 21and 23, the blocking bar 68 is mounted forwardly and rearwardly movable on the frame swinging side edge 52. Furthermore, blocking bar 655 is mounted forwardly and rearwardly movable parallel to both the frame swinging side edge 52 and door swinging side edge 45, that is, the blocking bar outer side surface 83 is movable parallel to the inner side surface 84 of the frame swinging side edge 52, and the blocking bar inner side surface 85 is movable parallel to the side surface 86 of the door swinging side edge 45.

As shownthe blocking bar 68 is generally rectangular in overall configuration and extends substantially the entire vertical distance of the vestibule opening t3 between the frame top and bottom edges 53 and 54, and as best seen in FIG. 2, the blocking bar inner side surface 85 is preferably continuous and unbroken for forming a smooth surface covering the frame swinging side edge 52 and thereby a smooth side surface for the vestibule opening 43', particularly important when the door 40 is in open position and the blocking bar 68 is moved forwardly to its blocking position, as shown in FIG. 2. The blocking bar outer side surface 83 is formed with a series of appropriate cutouts and certain members mounted thereon for movement of the blocking bar 68, as will be hereinafter described in detail. Y

Referring particularly to FIGS. 2, l through 17, 20

p and 21, blocking bar 68 is supported on the frame swing-V Ving side edge 52 for forward and rearward horizontal movement relative to the frame swinging side edge by the roller support, generally indicated at 87, formed partially on the blocking bar and partially on the frame swinging side edge. Asbest seen in FIGS.. l5 and 17, a roller support bar 8S is horizontally secured to the blocking bar 68 at the blocking bar outer side surfaces 83 and extending laterally into a recess 89 formed in the inner side surface $4 of the frame swinging side edge 52 intermediate the height of the blocking bar and the frame swinging side edge. Furthermore, a similar but inverted roller support bar 90 is secured horizontally within the recess' 89to` the frame swinging side edge 52 beneath and generally vertically aligned with the roller support bar 88' of the blocking bar 68.

As shown, each of the roller support bars 83 and 90 are formed with opposed semi-circular ball grooves 91 and 92, respectively, with groove 91 opening downwardly and groove 92 opening upwardly. Mounted within these grooves 91 and 92 are a series of horizontally spaced supporting balls 93 maintained horizontally spaced by the spacing balls 94 of slightly smaller diameter. Finally, appropriate stops 95 and 96 are formed on the roller support bar 8S of blocking bar 63 and appropriate stops 97 and 98 are formed on the roller support bar 90 on the frame swinging side edge 52, filling the ends of the ball grooves 91 and 92 to limit the forward and rearward horizontal movement of the blocking bar 68 relative to the frame swinging side edge 52.

Thus, by mounting the roller support bar 8S horizontally on the blocking bar 63, the roller support bar 90 horizontally on the frame swinging side edge 52, and theV supporting balls 93 in the ball grooves 91 and 92, main-V taining the roller support bars 8S and 90 spaced vertically apart but still securely supporting blockingbar 68 on the frame swinging side edge 52, a smooth easy forward and rearward horizontal movement is provided for the blocking bar relative to the frame swinging side edge despite the extensive weight of the blocking bar. Furthermore, the extent of the forward and rearward movement of blocking bar 68 relative to the frame swinging side edge 52 is easilyl predetermined by the placement of the variousV stops 95, 96, 7 and 93 in the ball grooves 91 and 92, so that these stops may determine and limit the rearward movement of the blocking bar and, in combination with the frame swinging side edge projection 67 and blocking bar notch 69, the forward movement of the blocking bar.

The lateral stability for the blocking bar 68 during horizontal movement is provided by the lateral stabilizer, generally indicated at 99 and shown in FIGS. l5 and 16. This lateral stabilizer 99 is formed by a roller block 100 secured to blocking bar 68 near the upper end of this blocking bar and extending laterally into a recess 101 in the frame swinging side edge 52.

Lateral stabilizing roller 102 is mounted projecting upwardly from the blocking bar roller block 100, which roller is. received in a downwardly opening, forwardly and rearwardly, generally horizontal roller groove 103 formed in the roller guide bar 104 secured to the frame swinging side edge 52 within recess 101. The vertical support of the blocking bar 68 on the frame swinging side edge 52 bythe roller support 87 previously described, is such that the vertical positioning of this lateral stabilizing roller 102 is spaced vertically from the roller guide bar 104 within the roller groove 103, as shown, and sulficient clearance is provided at the sides of roller 102 within groove 103 for proper forward and rearward movement of the roller within the groove while the roller still maintains the blocking bar 68 generally vertical and moving generally parallel to the frame swinging side edge 52. Thus, the roller support 87 supports the blocking bar 68 on the frame swinging side edge 52 for. forward and' rearward movement, while the lateral stabilizer 99 maintains this blocking bar smoothly movable forwardly and rearwardly parallelV to the frame swinging` side edge.

As best seen in FIGS. 2, 3, l1 through 15 and 21 through 23, a wedge bar recess 105 is formed in the blocking bar outer side surface 83 in the rearward portion of this blocking bar 68 and extending preferably totally from top to bottom thereof. Intermediate the height of this recess 105 is laterally pivotally mounted the wedge bar 106. Wedge bar 106 is ofsubstantial vertical height v and is generally rectangular in cross section having appro-V priate cutouts and recesses for various mounting and operating purposes, as will be hereinafter described, while still having an effective full wedging part of full forward and rearward dimension and also of substantial vertical height as compared to the vertical extent of the blocking bar 68, as can be seen in FIGS. 2 and 15. Furthermore, wedge bar 106 in horizontal cross section extends generally forwardly and rearwardly and is provided with an inner side surface 1117, an outer side surface 108, a front end surface 109 and a rear end surface 110. The wedge bar 1116 is mounted near the front end surface 109 thereof laterally pivotal on the blocking bar 68 by the upper and lower pivot blocks 111 and 112 secured to the blocking bar 63 within wedge bar recess 105 receiving the vertically extending pivot pins 113 and 114- which are in turn pivotally received in the upper and lower ends 115 and 116 of wedge bar 1136. Thus, as shown in the drawings, the wedge bar 1116 is pivotally mounted on the blocking bar 68 movable between a generally forwardly and rearwardly non-wedging position substantially totally within the confines of the wedge bar recess 195 of the blocking bar 68 and a generally forwardly and rearwardly wedging position angling rearwardly and laterally outwardly partially angularly away from the blocking bar outer side surface 83.

As can be seen in FIGS. 3, l1 through 14, 18 and 19, but is best shown in FIG. 23, the frame swinging side edge S2 is also provided with a wedge bar receiving recess 117 of similar proportions to the wedge bar recess 105 in the blocking bar 63, and this wedge bar receiving recess 117 open laterally toward the blocking bar 68 and the door swinging side edge 45 when the door 441 is in closed position. This wedge bar receiving recess 117 is extended forwardly and rearwardly at certain appropriate vertical locations to provide for mounting and operation of various other elements, such as the previously described roller support S7 and lateral stabilizer 99, as well as other operating mechanism to be hereinafter described, but generally, this wedge bar receiving recess is of the configuration best seen in FIG. 23 throughout the major portion of the vertical distance that the wedge bar 166 is formed extending its major forward and rearward length, as can be determined from FIG. 15.

Furthermore, as shown, the wedge bar receiving recess 117 is generaly lateraly aligned with the wedge bar recess 1115 in blocking bar 68 when the blocking bar is in its fully forward or blocking position, again best seen in FIG. 23, and this wedge receiving recess is formed with a generally laterally and vertically extending rear surface 118 which is preferably slightly angled to conform with the rear end surface 11@ of the wedge bar 1116 when this wedge bar is angularly pivoted or extended to its wedging position partially received in the wedge bar receiving recess, that is, the position shown in broken lines in FIG. 23 and otherwise in FiGS. 14 and 19.

rfhus, when the wedge bar 166 is in non-wedging position in this particular rst embodiment of the present invention, this wedge bar is totally received within the wedge bar recess 1115' of blocking bar 68, so' that the blocking bar is free to move forwardly and rearwardly into and out of the opening or clearance space 66 between the inner side surface 8d of the frame swinging side edge 52 and the side surface 86 of the door swinging side edge 45, as shown in full lines in FIG. 23 and also shown in FIGS. 11 and 12.

When the wedge bar 1116 is pivoted to its wedging position, however, as shown in broken lines in FIG. 23 and also seen in FIGS. 3 and 14, the wedge bar front end surface 1119 remains rearwardly adjacent the generally laterally and vertically extending front end surface 119 of the wedge bar recess 165, which front end surface 119 is slightly angled to accommodate the pivotal movement of wedge bar 1116. Also, the wedge bar 106 when in this pivoted wedging position extends angularly rearwardly and laterally into the wedge bar receiving recess 117 in the frame swinging side edge 52, with the rear end surface 1111 of wedge bar 1116 adjacent and forwardly aligned with the rear surface 118 of the wedge bar receiving recess 117, so that the wedge bar 1116 is in an edgewise wedging position angularly between the blocking bar 68 and the frame 1f). swinging side edge 52 and is engaged with appropriate shoulders or surfaces on these members resisting any rearward movement of the blocking bar 68 from its fully forward blocking position.

Thus, the wedge bar 1116 has an effective wedging vertical height of substantial vertical dimensions and provides a secure wedge between the frame swinging side edge 52 and blocking bar 68, maintaining the blocking bar in its fully forward blocking position.

Operating means, generally indicated at 120, and as best seen in FIGS. 3, 9, 10 and 15, is provided for moving in proper sequence both the blocking bar 68 forward to blocking position and rearward to non-blocking position and the wedge bar 1116 between non-wedging and wedging positions. Referring for the moment to FIGS. 3, 9 and l0, a usual electric drive motor 121 is mounted at a rear portion within the Valt wall 42 outwardly adjacent the frame swinging side edge S2 and this motor 121 is operably connected through appropriate gearing, generally indicated at 122, to a drive gear 123 positioned rearwardly of the frame swinging side edge S2.

Drive gear 123 is operably connected to a forwardly and rearwardly movable drive rack 124, which drive rack is positioned forwardly and rearwardly movable in an appropriate recess in the frame swinging side edge 52. Drive rack 124 is mounted on the blocking bar outer side surface S3 through horizontally spaced rack mounting bolts 125 which are secured to the blocking bar and are received in forwardly and rearwardly extending horizontally spaced slots 126 formed horizontally through the drive rack 1241, so that the drive rack may move forwardly and rearwardly independent of or relative to the blocking bar 68 to the extent of slots 126, but otherwise must move forwardly and rearwardly with this drive rack.

The drive rack 124 is also operably connected to the wedge bar 1116 for moving the wedge bar between its nonwedging and wedging positions and relative to the blocking bar 6h, as best shown in FIGS. 3 and 11 through 15. As shown, a pivot block127 is mounted on the inner side of drive rack 124 extending into an appropriate cutout 128 formed in the wedge bar 1116, as best seen in FIG. 15, land this pivot block 127 inwardly of the drive rack 124 receives a vertically extending pivot pin 129 therethrough.

A pair of horizontally and laterally movable pivot links 131i are pivotally mounted at either end of pivot pin 129, with these pivot links in turn being also pivotally mounted on vertically mounted pivot pins 131 which are connected to the wedge bar 106 within the cutout 128, as shown. These latter pivot pins 131 are connected to the wedge bar 1116 within the cutout 128 intermediate the forward and rearward dimensions of the wedge bar 196 and the various pivot pins and pivot links are arranged such that forward movement of the drive rack 124 relative to the blocking bar 68, as permitted by the slots 126, will cause this drive rack to move the wedge bar 1116 from its nonwedging position totally within the wedge bar recess 105 of blocking bar 68 to its wedging position extending laterally from this wedge bar recess 1115 angularly rearwardly into the wedge bar recess 117 in the frame swinging side edge 52. Furthermore, reverse or rearward movement of the drive rack 124 relative to the blocking bar 68 will cause theopposite movement of the wedge bar 106, that is, from wedging tonon-wedging position. t

It is important to note, as seen in FIGS. 3 and 14, that when the drive rack 124 has moved forwardly relative to theii blocking bar 6810 the extent permitted by the slots 126, moving the wedge bar 166 from non-wedging position angularly laterally outwardly to wedging position, the pivot links 130 not only extend from the drive rack pivot block 127 to the wedge bar 106, but also, when the wedge bar is Vin full wedging position, these pivot links are angled slightly rearwardly from the pivot block to the wedge bar. The importance of this rearward angling of the pivot links 131) from the drive rack pivot block 127 to the wedge bar 1116, is that, with such positioning, the pivot connection Vwedging positions.

of these links to the wedge bar is rearwardlyof the pivot connection of these links to the drive rack 124, so that any attempted rearward driving of the blocking bar 68 from its fully forward blocking position will not tend to withdraw the wedge bar from its wedging position toward its non-wedging position. Rather, this withdrawing of the wedge bar toward non-wedging position would not occur until the pivot point on the drive rack passes and moves rearwardly of the pivot point on the wedge bar, and rearward driving of the blocking bar to this required extent would be prevented by the wedge bar engaged between the blocking bar and the frame swinging side edge 52.

The operation and movement of the blocking and wedge bars 68 and 106 between the various positions is best shown in FIGS. 11 through 14 in sequence from nonblocking and non-wedging positions to blocking and As shown in FIG. 1l, the blocking bar 63 is fully rearward in non-blocking position, the wedge bar 106 is in non-wedging position, and the drive rack 124 is in its maximum rearward position, with the rack mounting bolts 125 on the blocking bar at the forward extent of the drive rack slots 126.

Note at this point that the blocking bar front surface 70`isl rearward of the door swinging side rear corner 50, so that the door can be freely swung between open and closed positions as indicated by the broken line door positions shown in FIG. 1l. Also note that during this swinging movement of the door 40, this swinging side edge 45 must move laterally into and forwardly and rearwardly through the opening or clearance space 66 between the door swinging side edge 45 and the frame swinging side edge 52, with preferably the door swinging side rear corner 50 just closely clearing the projection 67 at the front edge of the door frame 41 as this rear corner swings by the door frame projection.

When it is desired to secure the door 40 in closed position, the door is swung to such closed position, as shown in full lines in FIG. 11, and through operation of the drive motor 121 in the appropriate direction, the drive rack 124 commences its forward movement. Although the rack mounting bolts 125 are at the forward extent of the drive rack slots 126, due to the linkage between the drive rack 124 and wedge bar 106 requiring a greater force for movement of the wedge bar from its present non-wedging toward wedging position being greater than the force required for forward movement of the blocking bar 68, this forward movement of the drive rack 124 will begin forward movement of the blocking bar 68 forwardly into the opening or clearance space 66, so that the rack mounting bolts 125 will remain at the forward ends of the drive rack slots 126. Even if this force comparison were not true, the same situation would prevail, since at this point, there would be interference between the wedge bar 106 andthe inner side surface 84 of the frame swinging side edge 52 throughout a large part of the vertical height of the wedge bar preventing this wedge bar from moving toward wedging position. Furthermore, appropriate guide rollers, such as the guide rollers 132 at the top and bottom edge of the wedge bar 106 may be provided, as well as similar appropriate rollers on the frame swinging side edge 52 as desired, for maintaining smooth forward movement of the blocking bar 68 despite any tendency of the wedge bar 106 to attempt to move toward wedging position. Referring next to FIG. 12, the drive rack 124 has just moved the blocking bar 68 to its fully forward blocking position, so that the projection 67 on the frame swinging side edge 52 has been received in the blocking bar notch 69 preventing further forward movement of the blocking bar, and the blocking bar fully occupies the opening or clearance space 66 between the frame swinging side edge 52 andthe door'swinging side edge 45.

At this point, the drive rack 124 has not reached its fully forward position and the rack mounting bolts 125 are still at the forward ends of the drive rack slots 126. Note, however,ithat with the blocking bar 68 in its fully forward blocking position or its maximum forward position, the wedge bar recess in the blocking bar is still preferably rearwardly of the door swinging side rear corner 50, so that virtually a solid blocking bar is presented in the clearance space 66 for resisting outward swinging movement of the door 40 toward open position.

Finally, as shown in the nal sequence in FIGS. 13 and 14, with the blocking bar 68 in its maximum forward position, continued forward movement of the drive rack 124 causes movement of this drive rack forwardly relative to the blocking bar, as permitted by the rack mounting bolts moving horizontally through the gear rack slots 126. During this final movement forward of the drive rack 124,'the drive rack, through the pivot links 130, moves the wedge bar 106 pivotally from non-wedging position totally within the wedge bar recess 105 to wedging position engaged angularly between the blocking bar 68 and the frame swinging side edge 52, as previously described.

Thus, as shown in FIG. 14, the blocking bar 68 is fully forward in blocking position preventing any forward swinging movement of the door 40, while the edgewise angular engagement of the wedge bar 106 between the blocking bar and the door frame 41 prevents any attempted rearward driving of the blocking bar from its blocking position.

Withdrawal of the blocking bar 68 from blocking position is just the reverse of that previously described, that is, the drive motor 121 is actuated in the appropriate direction beginning to move the drive rack 124 rearwardly, and this initial movement is rearwardly relative to the blocking bar 68 until the rack mounting bolts reach the forward ends of the drive rack slots 126, which initial movement moves the wedge bar 106 pivotally from wedging position, shown in FIG. 14, to non-wedging position, shown in FIG. l2, totally within the wedge bar recess 105 in the blocking bar. Finally, continued rearward movement Vof the drive rack 124 ultimately moves the blocking bar rearwardly to non-blocking position out of the clearance space 66 and clear the door swinging side edge 45, as shown in FIG. 1l.

Appropriate electric switches (not shown) are provided at the front surface 73 of the vault wall 42 or at any convenient location in the usual form, along with the necessary wiring circuit, for actuating the electric drive motor 121 to provide the operation described, with certain safety switches within this circuit to be hereinafter described. In the eventof failure of the drive motor 121 for any reason, hand operating means is provided in the form of a hand .crankshaft 133 rotatably mounted horizontally through the vault wall 42, arranged for engagement through a separable coupling 134 with the drive motor 121, as shown in FIGS. 3 and 10, and accessible through an appropriate opening, generally indicated at 135 in FIG. 1. As can be seen, rotation of the hand crankshaft 133 in the proper direction will rotate the drive motor 121, and in turn move the drive rack 124 in the same manner as if driven by the drive motor.

Also wired in the usual manner in the electrical circuit for the electric drive motor 121 are certain stop switches for terminating the forward and rearward movement of the drive rack 124. As shown in FIGS. 3, and 9 through 14, a normally-closed forward stop switch 136 is mounted at the rearward extremity of the frame swinging side edge 52 properly positioned for engagement and actuation by aswitch block 137 at the rearward end of the drive rack 124. As can be seen in FIG. 14, when the drive rack 124 reaches its maximum forward position, the switch block 137 will engage the forward stop switch 136, thereby stopping the electric drive motor 121.

A normally-open rearward stop switch 138, as shown in FIGS. 20 and 21, is also mounted at the rearward extremity of the frame swinging side edge 52 in proper position for engagement by the roller support bar 3S on the blocking bar 68. As is also shown in FIG. 15, this roller support bar S3 on blocking bar 58 is provided with an outer substantially continuous forwardly and rearwardly extending side surface 139 which is extended rearwardly of the actual roller support bar 35 by the extension member 149. At the proper location along this side surface 139 of roller support bar 88, there is formed a switch recess 141 which is of appropriate size for disengaging the rearward stop switch 133 when properly positioned relative thereto, as shown in FIG. 2l.

rThus, as the blocking bar 63 is moved rearwardly by the electric drive motor 121, the normally-open rearward stop switch 13b is maintained engaged by the surface 139 on the roller support bar Si? or the extension member Mil to thereby maintain the circuit to the electric drive motor, as shown in FlG. 20. When the drive rack reaches its maximum rearward position,` however, the switch recess 14:1 in the roller support bar is properly aligned with the rearward stop switch 138 and disengages this switch, to stop the electric drive motor 121 and consequently the rearward movement of the drive rack.

For locking the blocking bar 63 in its fully forward blocking position and the wedge bar 165 in its wedging position, a pair of combination locks 142 are mounted at the back surface of the vault wall 42, as best seen in FlGS. 9, and 22, which combination locks are provided with the bolts 1M operably connected by the pivotal tie bar 145. Tie bar 145 is in turn centrally pivotally connected to an actuating bar 1415, which extends laterally between locks 142, is pivotally connected to a pivot bar 147, and is solidly connected through a connector 143 to the laterally movable lock bar 149, as shown.

Pivot bar 147 is also pivotaily connected to the vault wall back surface 143 and the lock bar 149 is Amounted for lateral movement between positions overlying and free of overlying the drive rack 12d, as best illustrated in FIGS. 11 through 14. Furthermore, the various bars and connector 145 through 149 `are properly arranged so that withdrawal of both bolts 144 of the combination locks 1d-2 will move the lock bar laterally suficiently so as to be free from overlying thedrive rack 1de, whereas extension of one or both of these bolts 144 will maintain the lock bar 149 in a lateral position still overlying drive rack 124.

As can be seen in FlGS. 3, and 9 through 15, a locking block is mounted on the top surface of the drive rack 12d-properly positioned so that, when the drive rack 124 is in its forwarumost position with the blocking bar 63 in its forwardmost blocking position, and the wedge bar 1% in its wedging position, this locking block 151i will be located immediately forward of the path of lateral movement of the lock bar 14,9 actuated by the combination locks 142. Thus, as best seen in FiGS. 3 and 14, with the drive rack 124 in its fully forward position, extension of one or both of the bolts 144 of the combination locks 142 will move the lock bar 149 laterally behind the drive rack locking block 151i, to thereby prevent withdrawal -or rearward movement of the drive rack 124 and lock both the blocking bar 63 in blocking position and the wedge bar 1% in wedging position.

Furthermore, `when both of the bolts V14d of combina-` tion locks 1412 are withdrawn, thelock bar 149 is moved laterally free of rearward blocking or locking the drive rack locking block 1751i, so that the drive rack 124 is free to be moved rearwardly for moving the wedge bar 166 to non-wedging position and the blocking bar 65 rearwardly to non-blocking position free of interference `with the door d. Although in the particular embodiment` shown,

the linkage between the combination locks 142 and the,

lock'bar 11i-9 is such that both of the bolts 144 must be withdrawn or moved to unlocked position before the lock bar 1119 is clear of locking the drive rack 124, it is possible to arrange this linkage if desired so that withdrawal of only one of the bolts 144 will accomplish the unlocking action.

As shown in FEGS. 9 and 10, normally-closed control switches 151 may be incoroorated in the electrical circuit for the electric drive motor 121 so that this drive motor cannot be actuated for withdrawal or rearward movement of the drive rack 12d until both of the combination lock bolts 144 have been withdrawn. As shown, when both of the bolts 1414 are withdrawn, these control switches 151 are disengaged to complete the electrical circuit therethrough to the electric drive motor 121.

The combination locks 142 are operated from the front of the vault wall d2 by an operating knob 152 projecting outwardly of the front surface 73 of the vault wall d2, as best seen in FlGS. l and 22. This operating knob 152, as best seen in FG. 22, is connected to a rotatable dial shaft 153 which extends rearwardly through the vault wall t2 to a location between the combination locks 142.

The mounting of the dial shaft 153 is such that by limited forward and rearward movement of the operating knob 152, the dial shaft 153 is moved axially forwardly and rearwardly, and this limited forward and rearward movement of the dial shaft 153 is controlled by a detent mechanism, generally indicated at 15d, and comprising the spring-urged dogs 155 received in the positioning grooves 156, as shown. A pair of gear collars 157 are separately rotatably mounted axially adjacent over the dial shaft 153 at the location of the combination locks 1412 and a pair of drive eys are mounted on the dial shaft 153 for alternate engagement as a result of forward and rearward movement of the dial shaft in the drive slots159 of the gear collars 157. Furthermore, each of these gear collars 157 is operably connected to one of the combination locks 14.2 for the usual manipulation of that particular combination lock to set the combination thereof and move the bolt 1de? to unlocked position.

Thus, by moving the dial shaft 153 either forwardly or rearwardly for manipulating the particular combination lock, with the proper setting of these locks, the bolts 144 may be withdrawn or extended. Also, the particular setting of the combination locks 142 may be determined from the dial 160 mounted on the dial shaft 153 forwardly of the front surface 73 of the vault wall d2, as shown.

This dial 160 is positioned within a control box 161 with the operating knob 152 accessible forwardly of this control box 161. Further, the dial 160 is keyed to the dial shaft 153 permitting limited forward and rearward movement of the dial shaft, but with the dial at all times rotatable exactly. with the dial shaft.

As shown in FIG. 2, the dial 16h is Visible'downwardly through a sight opening 162 of the control box 161 for determining the setting of the dial shaft 153 to set the combination locks 142 visually. If desired, a digital readout device, generally indicated at 163, with the appropriate electrical circuit therefor (not shown), may be incorporated with this combination lock mechanism described and thedial shaft 153, such digital readout device being disclosed in the co-pending U.S. patent application of Thomas `Kenny et al., entitled Digital Readout Combination Lock Construction, Serial No. 109,445, filed May 11, 1961. I n the case ofthe use of the digital readout device 163 for determining the Vcombination lock settings, the sight opening 162 may be covered and reserved only for emergency use.

In addition to the combination locks 142 for locking blocking bar 68 and wedge bar 195 in their blocking and wedging positions, `a time lock mechanism, generally indicated at 164, may also be provided, as best seen in FIGS. 9, 10, 18 and 19. As shown, the time lock 1155 is mounted at the rearward surface of the vault wall 42 above the combination locks 142, and a lock bar 166 i for the time lock is laterally pivotally mounted on the frame swinging side edge 52 extending forwardly to the lateral Ilocation of the rearward portion of wedge bar 1% 15 when the blocking bar 68 is in fully forward blocking position.

An engagement plate 167 is mounted at the forward end of and pivotally movable with the lock bar 166, and this engagement plate is formed with a specifically contoured engagement recess 168 opening forwardly and laterally toward the rear portion of the wedge bar 106. At the vertical location of this engagement plate 167 on lock bar 166, the wedge bar 106 is provided with a specifically formed engagement insert 169, shown in cross section in FIGS. 18 and 19 and in side elevation in FIG. 15, which insert is specifically contoured to be engaged in the engagement recess 168 by the engagement plate 167 when the wedge bar 106 is in wedging position, as shown in FIG. 19.

In view of the lateral pivotal mounting of the lock bar 166, when the time lock 165 is in unlocked position, the lock bar is free to pivot, as shown in FIG. 18, to thereby permit the wedge bar 106 to move freely between non-wedging and wedging positions, and this pivoted position of lock bar 166 is the normal position thereof unless and until engaged with the wedge bar 106 when the wedge bar is moved to wedglng position, as shown in FIG. 19. When the wedge bar is moved to wedging position, it urges the lock bar 166 pivotally to the position shown `in FIG. 19, and if the time lock is then locked, the engagement of the engagement plate 167 of lock bar 166 with the engagement insert 169 of Wedge bar 106 will prevent or block any movement of the wedge bar toward non-wedging position, and in this manner, the time lock 165 may lock the wedge bar 106 in wedging position and the blocking bar 68 in blocking position, since the blocking bar cannot be moved from blocking position until the wedge bar is moved to non-wedging position.

Thus, in general operation of the irst embodiment of the vault door construction of the present invention, when the door 40 is in open position with the blocking bar 68 rearward in non-blocking position and the wedge bar 106 in non-wedging-position, the door is swung closed, as shown in FIG. 11, after which, the blocking bar is moved fully forward to blocking position, as

shown in FIG. 12, by forward movement of the drive rack 124, as previously described. After the blocking` bar is in blocking position, continued forward movement of the drive rack moves the wedge bar 106 to wedging position in the sequence shown in FIGS. 13 and 14. With the blocking bar 68 fully forward in blocking position filling the opening or clearance space 66 between this blocking bar and the frame swinging side edge 52, door 40 is blocked against opening swinging movement, and the positioning of the wedge bar 106 in wedging position, angularly laterally engaged between the blocking bar and the frame swinging side edge, prevents any rearwardmovement of `the blocking bar, whether from an outside driving force or otherwise.

To complete the door locking operation, the bolts 144 of combination locks 142 are then thrown to locked position which moves the lock bar 149, operably connected to thesefcombination locks, behind the drive Y rack locking block 150, thereby locking both the wedge n closed position.` Also, with the proper setting of the"V time lock 165 to a locked position, the lock bar 166 for this time lock will be pivoted by-the movement of the wedge barV 106 toV wedging position such that this wedge bar is held in wedging position until the time lock is unlocked, thereby further locking the wedge bar-in wedgi moved toward` non-wedging position. Operation of thecombination locks 142 will withdraw the bolts 144, thereby withdrawing the lock bar 149 to permit rearward movement of the drive rack 124. Thus, the drive rack 124 may be moved rearwardly and the reverse sequence of FIGS. 11 through 14 takes place, until the wedge bar 106 has moved to non-wedging position and the blocking bar 68 has moved fully rearwardly to non-blocking position, freeing the door 40 for forward swinging movement through the clearance space 66 between this door and the frame swinging side edge 52.

When the door 40 is swung forwardly to open position, the blocking bar 68 may be again moved forwardly to its blocking position, again occupying the clearance space 66 and therefore preventing the door 40 from being moved fully to closed position. This will not only prevent the door from being closed, but also positions the blocking bar plain inner side surface for forming that side surface of the vestibule opening 43, as shown in FIG. 2. This forward positioning of the blocking bar 68 coupled with the continuous groove and rib appearance at the opposite side of the vestibule opening 43 presented by the door h'mged side edge 44 and frame hinged side edge 51 when the door 40 is fully open, as shown in FIG. 4, provides a pleasing appearance for the vestibule openin 43.

gThe second embodiment of the vault door construction of the present invention, shown in FIGS. 25 through 33, is substantially the same as the rst embodiment construction, with the exception of the operable connection of the operating means with the blocking and wedge bars, the mounting of the wedge bar and the manner in which the wedge bar is locked in wedging position by the time lock means, and the manner in which the wedge bar engages the blocking bar. For this reason, only this portion of the construction is shown in this Isecond embodiment.

As shown, the blocking bar 268 is movable forwardly and rearwardly into and out of the opening or clearance space 266 between the frame swinging side edge 252 and the door swinging side edge 245 of the vault door 240. Furthermore, the wedge bar 306 is movable between a non-wedging position, shown in FIGS. 25, 27 and 28, and a wedging position, shown in FIG. 24, when the blocking bar 268 is fully forward in its blocking position.

In this second embodiment, however, the wedge bar 306 is pivotally mounted on the frame swinging side edge 252 within a recess 370 of the frame swinging side edge and immediately forward of a shoulder 371 thereof, as best seen in FIGS. 24 and 30. Still further, when the wedge bar 306 is pivoted angularly and laterally to its wedging position, the front end surface 309 thereof is received rearwardly within a recess 372 rearwardly adjacent a generally lateral, somewhat angled surface 373 of the blocking bar 268, so that the wedge bar is edgewise and angularly wedged between the blocking bar and the frame swinging side edge 252.

Also, it is preferred to form the recess 372 of the blocking bar 268 in a shear wedge 391 formed as a part of the blocking bar. Shear wedge 391 in horizontal cross section is generally triangular in configuration, decreasing in lateral width forwardly, and terminating forwardly in a relatively sharp nose portion 392. Furthermore, this shear wedge 391 extends vertically on the blocking bar 268 at least the same vertical extent as the vertical extent of the wedge bar 306, and this shear wedge 391 is attached tothe blocking bar 268 by means such as welding only a pre-calculated amount, sufficient for normal operation of the construction. i

The purpose of the shear wedge 391 is that, when the blocking bar 268 is in fully forward blocking position and the wedgebar 306 is engaged therewith in wedging position, as shown in FIGS. 24 and 30, any rearward driving of the blocking bar 268 in an attempt to move this blocking bar rearwardly out of blocking position Ywill cause the shear wedge 391 to shear loose from the blocking bar. This will result in the sharp nose portion 392 of the shear wedge 391 to securely wedge between the blocking bar 268 and the frame swinging side edge 252, which will rmly wedge the blocking bar against further rearward movement. Also, when this shear wedge 391 is in this detached wedging position, any further rearward driving force against blocking bar 268 will only tend to more tightly wedge the shear wedge between the blocking bar and frame swinging side edge.

The operating means, generally indicated at 328, includes the drive rack 324 moved forwardly and rearwardly by the drive gear 323, and this drive rack is formed with a Wedge bar operating block 374 and a blocking bar operating block 375. As shown, the wedge bar operating block 374 is mounted for engagement with a roller 376 rotatably mounted on a pair of operating arms 377, which arms are in turn secured to the wedge bar 306. The blocking bar operating block 375 is formed with a slot 378 engaged by a dog 379, which dog is spring-urged laterally outwardly toward the blocking bar operating block 375.

This spring-urged dog 379 is mounted movable with the blocking bar 268 and is controlled for lateral movement by a cam block 380, which cam block is in turn controlled by a cam roller 381 mounted on the frame swinging side edge 252. As will be more clearly seen in the description of the operation of this second embodiment, progressive engagement or" the cam roller 381 with the cam block 380 will progressively laterally withdraw the dog 379 from the slot 378 in the blocking bar operating block 375 to disconnect operable connection between the blocking bar 268 and the drive rack 324.

The movement of the blocking bar 268 between blocking and non-blocking positions and the wedge bar 336 between wedging and non-wedging positions is shown in FIGS. 24, 25, 27 and 28. Starting with FIG. 24, the blocking bar 268 is fully forward in blocking position and the wedge bar 306 is in wedging position. Ignoring any locking by either combination locks or a time lock, for unlocking the door 249, the drive rack 324 begins to move rearwardly and, since as shown the cam roller 381 is engaged with the cam block 380 maintaining the dog 379 laterally withdrawn, there is no operable connection between the drive rack and the blocking bar.

After the drive rack 324 has moved rearwardly a short distance, the wedge bar operating block 374 engages the roller 376 connected to the wedge bar 336 and the progressive rearward movement of the drive rack pivots the wedge bar laterally to non-wedging position, fully within the frame swinging side edge 252, as shown in FIG. 25. During this same rearward movement of the drive rack 324, the cam block 380 has moved progressively rearwardly along the cam roller 381, thereby beginning to release the dog 379 and permitting this dog to be resiliently urged progressively toward the slot 378 in the blocking bar operating block 375, so that finally, dog 379 engages with blocking bar operating block 375 locking the blocking bar movable rearwardly with the drive rack, as shown in FIG. 27, and this connection remains until the blocking bar is free of interference with the door 245 so that the door can move freely through the clearance space 266 to open position.

Moving the blocking bar 268 from non-blocking to blocking positions is substantially opposite to that just described for withdrawal of the same, however, operation of the wedge bar 366 from non-wedging to wedging position is slightly different. The operable connection during forward movement of the drive rack 324 with the blocking bar 268 is maintained by the dog 379 engaged in the blocking bar operating block 375 until the blocking bar is fully forward in blocking position, at which time the cam roller 381 has engaged the cam block 380 to laterally withdraw dog 379 and cease the oper- 18 able connection between the blocking bar and the drive rack.

At this time, as shown in FIG. 28, the wedge bar 306 is in a non-wedging position so that the wedge bar operating block 374 will have no effect on the wedge bar 306, but rather this wedge bar operating block moves freely away from the roller 376 of the wedge bar, while the wedge bar remains in non-wedging position. As the drive rack 324. continues forwardly, however, a lateral ange 382 forward of the blocking bar operating block 375 engages the roller 376 of the wedge bar 306, so that the final forward movement of the drive rack 324 moves this flange 382 forwardly and thereby pivots the wedge bar 386 laterally outwardly to its angular wedging position against the blocking bar 268 and between this blocking bar and the frame swinging side edge 252.

The lock bar 349 for the combination locks (not shown) is similarly laterally movable by the combination locks as in the rst embodiment and for locking engages behind a locking block 350 secured to the drive rack 324, as shown for instance, in FIG. 24 in locked position and in FIGS. 25, 27 and 28 in unlocked position. In this manner, therefore, similar to the first embodiment, the drive rack is locked in its fully forward position, thereby locking the blocking bar 268 in blocking position and the wedge bar 306 in wedging position wedged between the blocking bar and the frame swinging side edge 252.

The locking by the time lock (not shown) in this second embodiment is accomplished by vertically moving a pair of wedge-shaped segments or members 383 laterally behind lthe wedge bar 306 when this wedge bar is in wedging position, so that these wedge members 383 are positioned between the wedge bar 306 and a portion of the frame swinging side edge 252 within the recess 378 of the frame swinging side edge, as shown in FIGS. 24, and 30 through 32. These wedge members 383 are moved vertically by the vertically extending racks 384, which racks are secured to the wedge members 383 and are vertically movable by a rotatable drive gear 385.

As best seen in FIGS. 32 and 33, the drive gear 385 is mounted on a drive shaft 386 which is in turn operably connected to and rotated by a control shaft 387 extending forwardly through the vault wall 242 and arranged for hand rotation. Intermediate the drive gear 385 and the control shaft 387, the drive shaft 386 mounts a locking plate 388 having a locking recess 389 for receiving a locking roller 390 mounted on a forwardly and rearwardly movable, but forwardly spring-urged, lock bar 366.

Lock bar 366 is arranged with the usual time lock so that when the time lock (not shown) is unlocked, the lock bar is freely movable forwardly and rearwardly, but is normally spring-urged forwardly, and when the time lock is locked with the lock bar 366 forwardly, which places locking roller 390 in the recess 389 of the locking plate 388, this time lock prevents any rearward movement of lock bar 366. Since locking plate 388 is secured to the drive shaft 386, this will prevent any rotation of this drive shaft and the drive gear 385.

Thus, when the time lock is unlocked, due to the free forward and rearward movement of the lock bar 366, the wedge members 383 may be moved to the position shown in broken lines in FIG. 31, and due to cutouts in the wedge bar 386, these wedge members will be free of interference with the movement of the wedge bar. When, however, the wedge bar 386 is in wedging position, as shown for instance in FIG. 24, these wedge members 383 may be moved vertically to the full line positions of FIG. 3l and will be positioned between the wedge bar and the frame swinging side edge 252, thereby preventing movement of the wedge bar from wedging position. At this time, with the time lock locked, the lock bar 366 will be spring-urged forwardly engaging the locking roller 390 with the locking plate 388 preventing vertical movement of wedge members 383, thereby again locking both the wedge bar 306 in wedging position and the blocking bar 268 in blocking position.

Thus, in both embodiments of the vault door construction of the present invention, a blocking bar is provided for securely maintaining the vault door in closed position, replacing the complicated bolt work of the prior constructions. Further, a wedge bar is provided for wedging the blocking bar in blocking position, which wedge bar wedges angularly edgewise and laterally between the blocking bar and the vault door frame. Also, the usual form of lock means are provided for locking the wedge bar in wedging position and the blocking bar in blocking position.

In the foregoing description, certain terms have been used for brevity, clearness and understanding but no unnecessary limitations are to be implied therefrom, because such words are used for descriptive purposes herein and are intended to be broadly construed.

Moreover, the embodiments of the improved construction illustrated and described herein are by way of example and the scope of the present invention is not limited to the exact details of construction shown.

Having now described the invention, the construction, operation and use of preferred embodiments thereof, and the advantageous new and useful results obtained thereby, the new and useful construction and reasonable mechanical equivalents thereof obvious to those skilled in the art are set forth in the appended claims.
