Description

1955 J. s. MATTHEW DOOR HOLDING DEVICE Filed May 26, 1952 mm T. NH ET T A M s .S E M Mw United States Patent DOOR HOLDING DEVICE James S. Matthew, St. Helens, Oreg. Application May 26, 1952, Serial No. 289,979 1 Claim. (Cl. 292-272) This invention relates to a door holding and locking device, and is particularly adapted to swinging doors.
The primary object of the invention is to provide means to automatically lock a door when in closed position and to hold a door open at approximately 90 degrees to the door opening.
A further object of the invention is to provide a door holder that automatically locks itself when the door is swung to open position.
A further object of the invention is to provide means associated with the automatic door holder to lock the door when it is in closed position.
These and other incidental objects will be apparent in I the drawings, specification and claim.
Referring to the drawings:
Figure 1 is a front view of my new and improved door holding device, showing the door in closed or locked position.
Figure 2 is a plan sectional view, taken through the door on line 2-2 of Figure 1.
Figure 3 is a similar section, but showing the door opened 90 degrees to the building, parts being broken away for convenience of illustration.
Figure 4 is an enlarged detail plan sectional view, taken on line 44 of Figure Figure 5 is an enlarged detail sectional view, taken on line 5-5 of Figure 1, looking in the direction indicated by the arrow.
Figure 6 is a sectional view, taken on line 6-6 of Figure 4, looking in the direction indicated by the arrows.
Figure 7 is a detail horizontal section through the end of the channel member of the pin, when the door is open.
Referring more specifically to the drawings:
My new and improved door holder unit 1, comprising a pair of wings 2 and 3. The wing 2 is secured to the wall 4 of a building by the screws 5, while the wing 3 is secured to the door 6 by the screws 7.
e hinge wing 3 has an extension 8 in the form of a channel have slots or guideways 10 formed end of each guideway 10 having a depression 22, one wall 23 of each depression being straight, as best illustrated in Figures 2 and 3. The wing 2 of the hinge unit has outwardly extending cars 11 to which is pivoted on a in 13 one end of a brace 12.
he brace 12 comprises a rod 14 and end portions or 15 and 16. The casing 15 is pivotally connected to the cars 11 of the wing 2 of the hinge 1. The rod 14 extends through the end wall 17 of the casing 15 and is looked thereto by the lock nuts 18. The casing 16 fits in the channel member 8, and is provided with a pin 19, the ends of which engage in the guideways 10 formed in the flanges 9. The rod 14 also extends through the end wall 16' of the casing 16 and is likewise locked thereto by lock nuts 18'. Obviously, the effective length between the end portions or casings 15 and 16 may be selectively varied by adjustment of the lock nuts 18 and 18'.
When the door is opened, the pin 19 will slide along the guideways 10 until it reaches the position shown in Figure 3, at which time the edge 21 of the casing 16 engages a flat spring secured to the channel member 8, the spring forcing the pin 19 into the depressions 22, thus holding the door open. The straight edges 23 of the walls of the depressions, when the door is in open position, are at right angles to the center line of the brace 12,
consists of a hinge r member. The flanges 9 of the channel member therein, the extreme 2,699,352 Patented Jan. 11, 1955 as illustrated in Figure 3. Therefore any attempt to close the door will exert a pull of the pin 19 against the straight edges 23 of the walls of the depressions, directly parallel in line with the axis of the bar 14 thus preventing the door being moved. The spring 20 holds the pin 19 in the position shown in Figure 3.
When it is desired to close the door, pressure is exerted against the end 24 of the casing 16 which forces the pin 19 against the spring 20 until the pin is in position to travel freely in the guideways-10. When the pin 19 is free to travel in the guideways, the door can be closed.
25 indicates a mechanical finger or wedge, having an extended operating handle 26 guided in a guide 27. The handle 26 extends to the opposite edge of the door so that the operator need not directly reach the casing 16 to disengage the bolt from the depressions.
In addition to the means described for holding a door open, I provide a locking bolt 28 actuated by a spring 29, to hold the door in closed and locked position. One end of the spring 29 bears against a guide 30, while the opposlte end of said spring bears against a. cross pin 31 in the locking bolt 28, the spring tending to hold the said bolt in the keeper 32 located in the jamb 33 of the door opening or engaging the edge of an oppositely disposed door, the latter not being illustrated.
A bell crank lever 34 is pivotally mounted between the the locking bo lever 34 at 40.
Mounted within the casing 16 is a locking unit 41. Passing through this unit is a plunger 42, the inner end 43 of which lies adjacent the arm 44 of the bell crank lever 34, when the door is closed.
the tension of the spring, the inner end 43 will engage the bell crank lever and pull the rod 37, and the locking bolt 28, withdrawing the latter from the keeper 32, thus permitting the door to swing open. The plunger 42 will be returned to its normal position by the spring 46. To prevent the plunger from being pushed inwardly until action is necessary to release the door, a lock 47 of any standard design is provided.
Referring particularly to Figures 4 and 6, the lock 47 includes a rotatable wedge 49, designed to cooperate with a groove formed in the plunger 42. In the drawing the wedge 49 is shown in engagement with the groove in fuil lines, and in dotted lines disengaged from the groove, to permit the operator to push the plunger towards the arm 44 of the bell crank lever 34, to withdraw the locking bolt 47, which revolves the locking wedge 49 to the broken line position shown in Figure 6, disengaging the same from the groove 50 in the plunger 42. The operator then pushes the plunger inwardly, which rocks the bell crank the keeper 32. The door may then be swung open to the position illustrated in Figure 3. As the door opens the pin 19 of the casing 16 of the brace 12, rides along the guideways 10, until it reaches the end of its travel, where it engages the spring 20 which forces it into the depression 22 as shown in Figure 3.
In the event the door tends to close, the pin 19 will be pulled directly against the straight edges 23 of the depressions, thus preventing the door being closed.
When it is desired to close the door, the operator either applies pressure to the end of the casing 16, or operates the wedge 24 to force the pin 19 against the tension of the spring 20. This removes the pin 19 from the depressions to the guideways 10.
The spring 29 maintains the locking bolt 28 in its 4 locked position, where it remains until the plunger 42 is engage the end of the bar to force the pin from the deagain operated against the bell crank lever 34. pression against the tension of the spring and into the What I claim is: guideways when shutting the door, and means for adjust- A door holder, comprising a channeled member adapted ing the length of said bar between said end portions. to be secured to a hinged door and a bar including two 5 end portiolrlisltlamla1 ofdwhich adac latettil to fie pnioted 1% a References Cited in the file of this patent wal to w ie t e oor is inge e c anne mem er having parallel guideways, at one end of which are lateral UNITED STATES PATENTS depressions, one wall of which is at right angles to the 851,192 Younglove Apr. 23, 1907 axis of the bar, the other bar end portion being fitted in 10 1,618,353 Rice Feb. 22, 1927 said chfimnel irinergber anal hating a pin i{:xtending therle- 1,898,562 More Feb. 21, 1933 t roug an tte in sai gui eways, a at spring int e channel member opposite the depressions in the guideways FOREIGN PATENTS to force the pin into the depressions when the door is 18,122 Norway Sept. 14,1908
