Description
This invention relates to an improved hinge hav~ng two hinge plates which are relatively pivotable about a pivot pin, and more particularly to an improved hinge of the "snap-in" variety used for windows and doors.
Numerous hinges for hanging doors and windows are known in the art and are generally provided with two hinge plates each having a hinge curl through which a pivot pin may be inserted. In the mass production of doors and windows for use, particularly, on large scale const^uction pro~ects, one of the requirements is that the door panels must be provided with (a) ready milled cutouts for the hinge plates and (b) hinge plates which must be such that the doors may be hung left or right merely by turning the door around, the hinges being symmetrically positioned on the door panel. In order to achieve this the hinges must be provided with loose hinge pins which are relatively easily lost with the result that costly time delays are often incurred awaiting new pins.
Further the projecting hinge curls make it very difficult to stack a pile of doors without damaging adjacent doors in the stack.
In order to overcome these problems there has been suggested, in Canadian Patent 925,26~ issued May 1, 1973 to A/S Grorud Jernvarefabrik, a snap-in hinge construction comprising a locking plate to be mounted on a door and a cooperating hinge plate member having a CO}l-ventional hinge pin and second hinge plate. The locking plate is mounted on a door having a conventional cut-out so as to provide, in cooperation with the cut-out, a space ., S
thereunder to receive -the eng~gement s-tructure of the hinye plate member. The locking plate, generally a thermoplastics material, is provided with a resilient locklng member and a locking tab which extends from the underside of the inner portion of the locking member to engage in a cut-out provided as the engagement structure of the hinge plate member. In such a structure the lock-ing plate may be mounted on the door at the factory and as there are no projecting parts from the plane of the door, the risk of damage during stacking and storage is minimized. The hinge plate member and its associated se.cond member and pin may be stored separately and the pin may be captive, thereby minimizing the loss problems.
Problems do, however, still remain. When the rela-tively sharp squared end of the hinge plate member is inserted into the space under the locking plate it exerts a planing action on the relatively soft thermoplastic depending locking member and in some cases actually completely shears it ofE. Even if the locking member is not sheared off, it is relatively difficult to see whether or not it has properly engaged in the slo-t in the hinge member as it is totally obscured from view from above.
It is, therefore, an object of the present invention to provide an improved "snap-in" hinge which avoids the difflculties and disadvantages of the prior art.
Thus, by one aspect of this lnvention there is provided a hinge construction for use on doors and the like t comprising, in combination:
(a) a locking plate adapted for mounting in a cut-out at the mounting edge of a door so as to provide, ~n cooperation with said cut~out, a space extending under -the locking plate and an elonqated opening thereto; and (b) a cooperating hinge plate member having means along one edge for receiving a hinge pin and having engage-ment means projecting from the plane of said plate member for releasable, cooperating engagement with said locking plate; said plate member being adapted for insertion into said elongated opening and said space under sai.d locking plate;
said locking plate including slot means in the plane -thereof adapted to receive and releasably retain said engagement means on said plate member.
The invention will be described in more detail hereinafter with reference to the accompanying drawings in which:-Figure 1 is a side view of thermoplastic locking plate accorcling to the prior art;
Figure 2 is a cross sectional view of the lockinq plate of Figure 1 mounted onto a door panel;
Figure 3 is a side view of the hinge member according to the prior art;
Figure 4 is a side vi.ew of a thermoplastic locking plate according to one embodiment of the present invention;
Figure 5 is a side view of the hinge member according to one embodiment of the present invention Figure ~ is a cross sectional view of the iocking plate of Fi.gure 4 mounted on a door panel, having inserted therein a hinge member of ~i.gure 5; and Figure 7 is a sketch showing how a door panel is set in place in a door frame.
Turning firstly to Figures l, 2 and 3 which are illus-trative of the prior art, there is provided a locking member 1, generally moulded from a thermoplastics material having a central. resilient tongue 2 and screw holes 3 for mounting the member l in a milled cut-out of a door 4 (Figure 2) in such a manner that the door has plane side surfaces and edges 6. The hinge member 7 has a curled edge 8 for receiving the hinge pin (not shown) and securing -the second hinge plate (not shown) thereto in conventional fashion and is provided with a slot 9. Hinge rnember 7 is inserted into the space 5 formed between the locking member l and door 4 as shown in Figure 2, in the direction of arrow 12 and is held in locking engagement with member 1 by means of a locking lug ll on the underside of tongue 2 which is resiliently urged into slot 9. It will be appreciated, however, that hinge member 7 is normally stamped from strip material and that the leading edge lO
thereof is frequently extremely sharp. As edge 10 contacts lug ll, upon insertion of the member 7 into space 5, a planing action on the relatively softer plastic material occurs and can result in the complete removal of lug ll.
In the event that only a portion of lug ll is removed the detritus may be carried forward towards face 13 and prevent the complete seating of member 7, and also prevent lug ll from completely engaging slot 9. It is, however, relatively difficult to see whether or not complete engagement has occured because tongue 2 completely obscures slot 9 from view~
Figures 4, 5 and 6 illustrate one embodiment of the present invention. In Figure 4 there is shown a door engaging plate 41, generally moulded from a substantially rigid ~ut resilient thermoplastics material such as Nylon, provided with screw holes 42 fGr securing it-to a milled cut-out of a door 4 in such a manner that the door has plane side surfaces and edges 6, as in the pxior art. Plate 41 is shaped so as to provide a space 5 between the underside thereof and the milled surface of the door, when plate 41 is secured to door 4 (as seen mos-t clearly in Figure 6).
Plate 41 is also provided with a relatively narrow substantially C shaped slot 43 having legs extending from each end thereof, and a substantially rectangular slot ~4 spaced slightly from slot 43, so as to provide a slightly resilient tongue 45. ~dge 46 of tongue 45 is generally chamfered as seen in Figure 6 so as -to prov.ide a lifting lip under which a screw driver or coin may be inserted to raise tongue 45 out of -the plane of door 4, as e~xplained in more detail hereina.Eter. H:inge plate 51, whi.ch is generally stamped from steel strip and shown in Figure 5, has a curled edge 52 for receiving the hinge pin (not shown3 and securing the seconci hinge plate (not shown) thereto in conventional manner. Plate 51 is provided with rounded corners and is complimentarily shaped to be recei.ved in space 5 under plate 41. ~ tongue 53 is lanced in -the centre so that, when plate 51 is inserted into space 5, s the end 54 -thereof engages with face 55 of slo-t 44 and so locks plate 51 into place. It will be appreciated -that as square face 54 projects away from the direction of insertion of plate 51 under plate 41 and only a sloped or ramp surface is presented, there is no ~anger of planlng the relatively softer material of plate 41, and furthermore tongue 53 is entirely visible through slot 44 so that a visual check of the completeness of location is straight-forward.
Should it be necessary to withdraw the hinge plate 51, it is merely necessary to insert a screwdriver blade or the edge of a coin under lip 46 and lever upwardly.
Tongue 45 is sufficiently resilient to move upwards so as to release edge 55 from engagement with tongue 53.
Figure 7 illustrates the manner in which the hinge of the present invention may be employed to hang a door or the like. It will, of course, be appreciated -that hinges of the present invention may equally well be employed to hang windows, shutters and the like and in furniture construction. Second hinge plates 71 are secured to a door frame in conventional manner. The plates 51 are hingedly ~ounted on respective plates 71 by means of hinye pins 72 which may be of the loose or captive variety. The door bearing plates 41 is -then lifted into position and located so that plates 41 may be inserted into respective spaces 5. A sharp push is all that is required to snap the hlnges into the fully locked position, without the use of tools.
