Application August 25, 1934, Serial No. 741,381
This invention relates to a hinge which is adapted to be concealed when in closed condition, in the frame and door in which it is used.
A principal object of the invention is to provide a hinge which will be entirely concealed from view when the door with which it is used is closed.
Another principal object is to provide a concealed hinge which will permit the opening of a door for substantially the full width of the doorway.
Another principal object is to provide cushioning means at the limit of the normal swing of the door, and thereby insure the hinge against the tendency to snap or strain the same when the door is opened with violence, at the same time eliminating str-aps which are sometimes used for this purpose, and which protrude from the door when the door is closed.
Another principal object of my invention is to provide means for manually holding a door open at a wider angle than the normal swing thereof.
Another principal object is to provide means for holding both sides of the hinge in rigid relation when the hinge is closed, to prevent sagging of one side with reference to the other.
Other objects will be apparent from reading this specification taken in connection with the accompanying drawings, in which Figure 1 is a perspective view of a door and body in which my hinge is used;
Figure 2 is a vertical view of my hinge in open condition;
Figure 3 is a detail showing one form of an urged pawl construction which may be used in my hinge; this view is taken from the reverse side of Figure 2;
Figure 4 is a cross section taken along the line 4-4 of Figure 2, looking in the direction of the arrow;
Figure 5 is a similar view to Figure 4, except that the cushioning means is in compression;
Figure 6 is a similar view in which the hinge is shown in closed position;
Figure 7 is a modification of the cushioning element of my invention, in which the heavy spring is disposed horizontally instead of vertically as shown in other figures of the drawings-Figure 4, for instance; and
Figure 8 is a modification of the cushioning element of my invention, in which the pawl is held in forward position without the use of a supplementary spring for that purpose as shown in Figure 3.
Referring now in detail to the drawings in which similar characters refer to similar parts throughout, D is a door and B is a body to which the door is hinged. The door and body are chambered at l and l I respectively to accommodate the operation of the hinge and conceal the same from View when the door is closed.
The door member of the hinge is provided with a plate P having an open frame protruding inwardly into the door D, the walls of which frame are shown at 5|, and which are partitioned at I2 10 and I3, said partitions being joined together at M, and secured to the side walls 5| by the screws Extending through the upper and lower walls 5| and through the partitions l2 and I3, is a hinge pin IT, on which are mounted the hinge straps l8 and 20. The other ends of these straps are mounted on the hinge pin Ila of the body side of the hinge. The hinge strap is integrally secured to the shaft I I to turn arcually 20 therewith, the purpose of which will be hereafter described. The strap I9 is mounted on the door side of the hinge on the hinge pin 23 mounted in the partitions l2 and I3, and is mounted in the body side of the hinge on the 25 hinge pin 23a, which hinge pin is supported by the partitions lZa and |3a of the body side of the hinge.
On the hinge pin ll, between the partitions l2 and I3, is mounted a stop 24, which is secured by means of a pin 25 to the hinge pin I1 and turns arcually therewith. The strap I9 is provided with a projecting rib 26, with which the free end of the strut 24 is adapted to contact, and prevent further opening movement of the hinge. Before this strut takes effect, however, the projecting catch 27 engages the pawl 28, which spring-cushions the further opening of the hinge, until the link I9 comes to rest on the stop 4|, when the strut will engage the projection 26.
Integral with each of the hinge straps l8 and 20 is a projecting catch 21, which engages the pawl 28, which pawl may be urged forward by the supplementary spring 29a as shown in Figure 3, or may depend upon its forward normal position in a construction which eliminates the supplementary spring, as is shown in Figure 8, the details of which will be hereafter described. The object is to project at all times the pawl 28 into the are described by the catch 21 of the hinge straps I8 and 20.
The body side of the hinge is provided with projecting walls 5la, which form a frame, in which frame are the partitions H11 and Ba which are joined together at [4a, in similar manner as has been described with reference to the door side of the hinge. Extending vertically through the upper and lower walls 51a is a hinge pin 29, on which are mounted lids 32 which are held in substantially vertical position when in repose, by the spring 30, the other end of which spring being rigidly held by the base 34 integral with the walls 5la. The said base and lid are provided with seats for the spring 30. A spring stop 35 is provided having the ends 36 which pass through the ears 31 on the walls In and I3a, and said stops extend over the lids 32, thereby limiting their upward movement due to the pressure of the spring 30. At the end of each of the lids 32 is swivelled at 38 the pawl 28, which is resiliently mounted so as to be constantly urged forward into the path of the projeoting catch 21, as above described. In Figure l, a supplementary spring 29a is used for this purpose. In Figure 8, which is a modified construction, the supplementary spring is eliminated, the forward urge of the pawl being controlled by the stationary plate 39, acting upon the short end of the pawl.
In Figure '1 a modified construction is shown in which the spring 30 is mounted in seats contained in the base 34a and the piston 3211, the outer movement of said piston being limited by the stop 36a. The piston 32a is hingeably linked at 42 to the pawl 28a, having the projecting catch 21a integral therewith. This projecting catch cooperates with the strap member 43 so that such member will act upon the catch 2111 after the door has been opened its normal width and is pressed into a still further open position,
Figures '1 and 8 are modifications of the urged pawl assembly shown at the left of Figures 4 and 5. In Figure 7, the strap 43 corresponds to the strap [8 of Figure 4. When the strap 43 is moved downwardly from the position illustrated, it will rock the pawl 28a on its pivot Ho, and through the link 42 will compress the spring 30. In Figure 8 the strap mounted on the pivot l1a, engages through its catch portion, the pawl 28, which is pivoted in the lid 32. When the strap is drawn down, as upon opening the door beyond normal, the pawl 28 is raised together with the lid 32, to which it is pivoted, said lid compressing the spring 38. Upon the lid 32 being returned to the position shown in Figure 8, the short end 40 of the pawl 28, will rest on the stationary plate 39 which will insure the constant engagement of the pawl 28 with the catch of the strap mounted on pivot l1a.
The base members 34 extend outwardly from the wall Ella and the plate P, as do also the partition walls [2 and I3 in the door side of the hinge extend from their frame. When the hinge is in closed position the base members 34 of the body side of the hinge frictionally enter the door side of the hinge straddling the projecting walls l2 and I3. This construction safeguards any possible tendency of the hinge members to sag.
In operation the hinge is shown in its full normal open position in Figure 1, where the catches 21 are in engagement with the pawls 28. If it is desired to open the door still further, this may be done by hand when the catches 21 will force the spring influenced pawls 28 outwardly until the middle strap l9 contacts with the stop 4! mounted between and projecting upwards from the partition walls I21; and l3a, and
upon being released the door will again assume the position shown in Figure 1. If the door is swung open with unnecessary force, either purposely or accidentally, the engagement of the catches 21 with the pawls 28 will act as a cushion for the hinge and thus prevent damage thereto.
The strut 24 being keyed to the hinge pin [1, moves idly therewith until said strut engages the strap 19, when further movement of the hinge in an outward direction will confine the swing of the strap [9 to the hinge pin 2311, from which point the said strap will continue movement until it contacts with the stop 4|, which limits the outward movement of the hinge. When the door is forced back in its cushioned space, the projecting catches 21 draw down the pawls 28, and with them the lids 32, compressing the springs 30. Upon the pressure being released from the door, the spring 39 will return the parts to repose, the lids 32 being limited in their upward movement by the stops 36.
I have shown and described what I believe to be the best embodiment of my invention. I do not desire to be limited in patent protection to the embodiment shown, but what I wish to cover by Letters Patent is set forth in the accompanying claims.
1. A hinge having two sides, one side being adapted to be attached to a body and the other side to a door to swing the door on said body, said hinge embodying a plurality of straps hingeably mounted at their opposite ends in said body and door sides respectively, catches integral with at least one of said straps so as to move therewith, said catches protruding outwardly from said straps, resiliently mounted pawls disposed in the field of travel of said catches, said pawls being adapted to be engaged by said catches prior to the normal full opening of the hinge, forming a cushion therefor, and then also being adapted to resiliently permit a wider opening of the hinge upon extraneous force being applied thereto.
2. A hinge having two sides, one side being adapted to be attached to a body and the other side to a door to swing the door on said body, said hinge embodying a plurality of straps hingeably mounted at their opposite ends in said body and door side respectively, catches integral with at least one of said straps so as to move therewith, said catches protruding outwardly from said straps, resiliently mounted pawls disposed in the field or travel of said catches prior to the normal full opening of the hinge, forming a cushion therefor, and then also being adapted to resiliently permit a wider opening of the hinge upon extraneous force being applied thereto, and complementary projections and recesses in both sides of the hinge, the projections in each side of the hinge being adapted to nest in the recesses in the other side of the hinge when the hinge is in closed position, and thereby hold both sides of the hinge against shifting.
3. The structure defined in claim 1 in which means are provided to urge the pawl forward into the field of travel of the catch.
4. The structure defined in claim 1 in which a spring is provided adapted to resist the action of the pawl when engaged by the catch.
