HINGING MEANS 4 Sheets-Sheet 4 Sept. l, 1953 Filed Aug. l, 1950 A TTOR/VY' Patented Sept. 1, 1953 UNITED STATES PATENT OFFICE 6 Claims.
The present invention relates to combined hinges and latching means for doors and it consists in the combinations, constructions and arrangements of parts herein decribed and claimed.
Generally there is provided a door construction which includes an upper and lower hinge pin at either side thereof and a centrally mounted handle connected with such hinge pins in such manner that a simple turning movement of the handle in one direction will retract the hinge pins on one side of the door while a movement in the other direction of the handle will cause a retraction of the other set of hinge pins. Means is also provided for locking `the pins upon one side of the door in their outer positions when the pins upon the one side of the door are retracted thus making it impossible to remove the entire door through the action of the aforesaid handle. The invention possesses many other novel features which will be brought out in the specication herebelow.
It is accordingly an object of the invention to provide a door construction having upper and lower hinge pins upon either side thereof and a handle for selectively releasing the pins upon one side of such door.
Another object of the invention is the provision of a mechanism of the character set fonth wherein means is provided for automatically locking the pins upon one side of the door in their outward positions when the pins upon the other side of said door are retracted.
A further object of the invention is the provision, in a mechanism of the character set forth, of a novel latch means for a spring hinge forming a part of the invention.
A still further object of the invention is the provision of a mechanism of the character set forth which is relatively simple in construction, inexpensive to manufacture and yet eifective and eihcent in use.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 8 is a view similar to Figure 7 but showing the mechanism in its condition when all hinge pins are in their normal outward positions,
Figure 9 is an enlarged vertical sectional view illustrating certain details of construction, and
Figures 10- to l2, inclusive, are schematic views illustrating the operation of a door embodying the present invention.
Referring more particularly to the drawings, there is shown therein a door frame having upper and lower transverse members I0 and II, respectively, and side members I2 and I3. A door is shown disposed in `the door frame and includes a front panel I4 which is interconnected with a rear panel I5 by means of a pair of vertically extending side members I6 and I1 which are, in turn, interconnected at their upper and lower ends with transverse members I8 and I9, respectively.
Centrally disposed in the door at a convenient height is a shaft 20 which extends through both of the panels Ill and I5 and has mounted thereon at either end thereof operating handles 2|. Of course, in certain cases such as, for example, a domestic refrigerator box, one of the handles` 2| may be omitted without in any manner changing the remainder of the mechanisms.
Spaced transversely from the shaft 210 adjacent each side of the door and journalled transversely in the front and rear panels, as indicated at 22, is a pair of axles 23 and 24 which have respectively aixed thereto discs '25 and 26. Adjacent the outer periphery of the disc 25 there is pivotally connected, as indicated at 21, the outer end of a link 2,8 which is provided with a longitudinally extending slot 29 adjacent Vits inner end. Pivoted to the disc 12'6 adjacent its periphery, as indicated at 30, is the `outer end of a link 3l whose inner end is provided with a longitudinally extending slot 32.
Aifuxed to the shaft 2t and extending generally in an upward direction therefrom between the panels I4 and I5 is an arm 33 to whose upper end is aihxed a forwardly 4extending pin l34` which extends transversely through the slots 29 and 32.
In housings 35 and 39 mounted in the members I6 and l1, respectively, adjacent the outer ends of the door there are vertically slidable hinge pins 31 and 38 and in like housings 39 and 43 positioned vertically below the housings 35 and 36 and in the lower end of the door there are mounted hinge pins 4| and 42.
Since each of the housings 35, 35, 39 and 40 is of identical construction, only the construction of housing 39 and its associated pins 4| will be described in detail and reference to Figures 5, 6 and 6a is made for this purpose. It will therein be seen that the housing 39 is provided with a vertically extending cylindrical opening 43 for the reception of the pin 4| and that the body of the housing 39 is provided with a rearward extension 44 which is hollow, as indicated at 45, and which hollow portion 45 communicates by a slot 45 with the interior of the recess 43. An upwardly extending flat spring 41 is ainxed to the lower end of the extension 44, as indicated at '48, by metal screws or the like and the upper end of the spring 41 is provided with an outwardly and horizontally directed latch member 49. The pin 4| is provided at its outer end with a head 50 which is integrally formed therewith and inwardly of which is an inwardly directed annular shoulder 5|. A tension spring 52 inter connects the inner end of the housing 39 and the pin 4| which it surrounds and the inner end of the pin has connected thereto, as indicated at 53, the outer end of a link hereinafter to be referred to.
Aixed to the transverse member is a pair of upwardly extending sockets 54 and 55 which are adapted to register vertically with the housings 39 and 40, respectively, and aiiixed to the transverse member l is a pair of downwardly directed socket members 56 and 51 which are adapted to register vertically with the housings 35 and 35. Each of the socket members 54 to 51, inclusive, isrprovided with a recess for the reception of the associated hinge pins 31, 38, 4| and 42. In the case of the socket member 54, this recess is indicated at 58,
Connected with the lower end of the hinge pin 31, as indicated at 59, is a rod 60 which extends substantially vertically downwardly and which is provided at its lower end with an integrally formed horizontally extending dog 8|. The rod 60 extends through a collar |52 the lower end of which abuts against the dog and the upper end of which abuts against a dog 63 which extends horizontally and which is integrally formed with a vertically extending rod 64 whose lower end is pivotally connected, as indicated at 65 to the disc 25 adjacent the periphery thereof and to the inner and upper half thereof. To the lower outer half of the disc 25 and adjacent the periphery thereof there is pivotally connected, as indicated at 69, the upper end of a rod 61 whose lower end is provided with an integrally formed dog 58 which abuts the underside of a collar 89. A rod is connected to the upper end of the hinge pin 4|, as heretofore indicated at 53, and extends through the collar 59 and is provided with an integrally formed relatively small horizontally extending portion 1| which abuts against the upper end of the collar 69. Integrally formed with the horizontal portion 1| is an upwardly and inwardly extending arm 12 which is provided at its upper end with an integrally formed head 13 which extends horizontally. The arm 12 extends through a horizontally extending at latch spring 4 14 whose inner end is mounted upon a bracket 15 attached to the panel I5. The outer end of the spring 14 is provided with' an integrally formed upwardly extending latch dog 18.
Attached to the lower end of the hinge pin 38 is a downwardly and vertically extending rod 11 provided with an integrally formed relatively small horizontally extending portion 18 which abuts the lower side of a collar 19 and which extends then downwardly and inwardly to form an arm having at its lower extremity a dog 8i. The rod 11 extends through the collar 19 and also extends through a flat latch spring 82 mounted at its inner end upon a bracket 83 aiiixed to the panel |5 and provided at its outer end with a latch dog 84.
A horizontally extending pin 85 extends slidably through a plate 86 carried by the bracket 83 and a plate B1 carried by a bracket 88 aixed to the panel I5.` Adog 89 is Ymounted upon the pin B5 between the plates 88 and 81 and is provided with shoulders 90 upon its inner side. A rod 9| interconnects the outer end of the pin 85 and the upper and inner section of the disc 26, as indicated at 92 and the inner end oi the pin 85 is connected by a link 93, as indicated at 94, with the upper arm 95 of a bell crank leverwhich .is pivoted upon a pin 96 adjacent the disc 25 and inwardly therefrom in the door. The bell crank lever is provided with an integrally formed lower arm 91 which extends into a slot 98 formed in the inner end of a horizontally extending rod 99 which is slidably mounted in a pair of spaced brackets |00 and |0| likewise aixed to the panel I5. To the lower end of the bracket |0| there is affixed one end of a tension spring |02 whose other end is connected with a rod |03 which is, in turn, pivotally connected with the lower inner section of the disc 25, as indicated at |04.
A substantially vertically extending rod |05 extends upwardly through the collar 19 and is provided with a head |08 at its upper end which head abuts against the upper side of the collar 19 and the rod |05 is pivotally connected to the upper outer section of the disc 26 adjacent its periphery, as indicated at |01.
To the lower inner segment of the disc 26 and adjacent the periphery thereof there is pivotally connected, as indicated at |08, a dependent rod |09 which extends through a collar I0 and which terminates in a head l which abuts against the underside of the collar ||0. A rod I2 is connected to the upper end of the hinge pin 42 and extends upwardly through the collar ||0 and is provided with a head ||3 which abuts against the upper side of the collar ||0. A pin ||4 extends slidably through the bracket 15 and through a bracket ||5 spaced outwardly therefrom and has mounted thereon a dog IIB having a shoulder ||1 upon its inner face. The pin H4 is connected with the lower inner segment of the disc 25 by a link Hia, and is connected at its inner end, as indicated at ||1a with a horizontally extending rod ||8 whose other end is connected to the lower arm ||9 of a bell crank lever pivoted upon a pin |20 adjacent the disc 26 but inwardly therefrom. The upper arm |2| of the bell crank lever extends into a slot |22 formed in the inner end of a locking member or rod |23 which extends through a pair of spaced brackets |24 and |25 ailixed to the panel l5, as indicated at |20 and |21, respectively.
To an upward extension of the bracket |24, indicated at |28, there is connected a Vtension spring |29 which is, in turn, connected with a actores rod whose other end is connected with the -upper inner segment of the .26, as indicated vat |3|. Outwardlyof the bracket |25 .the locking member |23 has mounted therein a stop member .|32 which is adapted to limit the inward movement of the locking member =|23 :and adiacent the inner end of the locking member 21.23 there is provided a transversely extending pin 33 against which abats a stop member |34 which is slidahly :mounted upon the locking member i123. A compression spring 435 surrounds `the locking member |23 .and bears against the stop Amember |34 and :against the bracket i214.
`The locking member 89 is provided with a stop pin |36 similar to the member 1.32 carried by `the locking member |23 `and with a stop member |31 and pin |33 similar `to members 34 and 123 carried .by the .locking member |23.. A compression spring |39 is mounted upon the locking member 99 and is similar construction and its mounting to the compression spring .associated with the .locking member |23.
The :disc `25 .is providedwith a 'notch |46 in its periphery and upon the inner side thereof while upon the outer .side thereof there vis `provided an outwardly exten-ding dog 14| which is adapted to' abut against the upper .side of a pin 142 mounted in the door.. The disc `26 is 4provided Vwith .a notch 14.3 in its periphery and upon its inner side while a dog i244 extends outwardly from the periphery of the disc 26 upon its outer side `and the dog `'Mil adapted to bear against the underside of the pin also mounted in the door.
y operation, it will belapparent that when the handle 2 as viewed in Figure l:l of the drawings, is moved to the left, `that isto sayin a clockwise direction :around theshaft 21| as `an axis that such .action will `cause the arm 33 to likewise move ina :clockwise Idirectitm or .the right as viewed in ing .the .collar 62 likewise in a downward -direction which action causes the rod 60 to likewise be brought in a downward direction due to the fact that the collar 62 is in engagement with the head 6i thereof.. rThis action, `in turn, will cause the hinge pin 3i to move rdo.wnwardly but of :engagement with the socket member (56 .and against lthe action of its associated spring 52.
During this operation, it will be apparent that the arm 61 will be moved in an upward direction thus carrying with it by means of the head 68 the collar 69 which since it abuts against the horizontal portion 1|, will cause the arm 10 and hence the hinge pin 4| to move in an upward direction out of the socket member 54 and against the action of the spring 52.
During these actions the upper end of the arm 12 will become disengaged from the dat spring 14 thus allowing the spring 14 to move upwardly whereupon its head 16 will engage upon the inner side of the shoulder ||1 which has been brought to its outermost extremity by the action of the link |6a moving the latch member ||4 to the left, again as viewed in Figure 1 of the drawings. This will cause the rod ||8 to move to the left thus pivoting in a clockwise direction the bell crank lever |9|2| to thus Vmove the pin |23 inwardly so that it will engage in the notch |43 in the disc 26 against the action of the compression spring |35. The door may then be opened upon the left side thereof, again as viewed in Figure l, while the hinge pins 38 and 42 remain engaged in their respective socket members 55 `and 51 to thus act as hinges for the door. It will be seen that the action of `the .pin |23 engaging in the notch |43 will prevent the pins 38 and 42 from becoming accidentally disengaged from their respective .socket members. When the door is thus opened the flat springs 41 carried by the housings 35 and 39 will be freed from their abutment lwith the associated socket members and will thus be allowed to have their heads 49 engage in the annular shoulders 5| to thus latch the pins 31 and 4| in their innermost positions thus .ensuring that the same will be cocked when the door is returned to its normal closed position.
When the door is so returned to its closed position, the socket members 54 will again abut against the springs 41 thus releasing the heads 49 from the shoulders 5| and allowing the springs 52 to again project the pins 31 and 4| into their respective sockets 58. This action will cause a. downward movement of the arm 1|)` and hence the horizontal portion 1| thus causing the hea-d 13 of the arm 12 to again engage the flat spring 14 thus releasing its head 16 from the shoulder ||1 land thus allowing the springs 4|29 and |35 to return the pin |23 to its normal disengaged position from the notch |43 in the disc 26.
To open the door from its other side, itis only necessary to move the handle 2| to the right as shown in Figure 1 thus causing the arm 3| to be moved to the left while the arm 28 remains in position, the pin 34 meantime traveling to the left in the slot 29. This action will cause the same action heretofore described to take place with regard to the hinge pins 38 and 42 and also with respect to the locking of the `disc 25 `and hence locking of the hinge pins 31 and 4| in their outermost positions. It will be Vapparent that instead of a dual handle as shown in Figure 4 ci the drawings, a sing-le handle may be `mounted upon the shaft 2| upon that side of the door which is normally approached. It will also be apparent that whenever either pair of hinge pins at one side of the door may be engaged in their outward positions that the pins upon the other side of the door are held in locked inward position and that also the action of the door is wholly controlled by the movement of the handle or handles 2|. This is `illustrated in Figures 10 11 and 12 `wherein in Figure 10 there is: illustrated the normal closed position of the door, while in Figure the door is shown as being hinged upon its right side as viewed in this ligure and, in Figure 12, the door is shown schematically as it would appear Iwhen the hinges upon the left side of the door are being utilized.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modiiications may be made without departing from the spirit of the invention or the scope of the appended claims.
