ONE-PIECE PLASTIC SEMI-ARTICULATED SELF-SPRING HINGE Filed Dec. 7, 1964 IIIIIIIIIII'IIII I I N VEN TOR.
JAMES B. CHAMPLIN BY dh ATTORNEY r 3,266,859 Ice Patented Aug 1966 Iowa Filed Dec. 7, 1964, Ser. No. 416,359 Claims. (Cl. 312-323) In the design of electronic cabinets and other enclosures, it is frequently necessary to provide a folddown or removable access panel or cover. Due to the thickness of the cover, it has normally been necessary to use a multipiece articulated hinge or to provide a pivot point well ahead of the outside surface. These solutions present drawbacks in aesthetic appearance, cost and removability.
The present invention relates to a one-piece plastic semiarticulated hinge which is small, light weight, inexpensive and simple, which is easy to mount and easily concealed behind the panel trim.
It is an object of this invention to provide an inexpensive, simple one-piece hinge.
Another object of this invention is to provide an improved hinge.
A feature of this invention is found in the provision for a one-piece hinge of plastic material of an improved design.
Further features, objects, and advantages "of this invention will become apparent from the following description and claims when read in view of the accompanying drawings, in which:
FIGURE 1 is a side view of the hinge of this invention;
FIGURE 2 is a view of the hinge of this invention with the door partially open;
FIGURE 3 is a view of the hinge of this invention with the door open;
FIGURE 4 illustrates the method in which the door can be completely removed from the cabinet;
FIGURE 5 illustrates the spring action in the hinge when the door is closed; and,
FIGURE 6 is an end view of the hinge.
FIGURE 1 illustrates a case 10 which has top wall 11 and bottom wall 112 to which a cover 13 is to be pivotally attached. The cover v13 has an extending lip 14 and a pair of hinges 16 according to this invention are attached to opposite sides of the cover by pivot pins '17. A latch attaches the upper end of the cover to the wall .11 and might comprise a first magnetic member 18 of one polarity attached to the wall 11 and a second magnetic member 19 of opposite polarity attached to the lip 21 of the cover 113. An adjacent cabinet 22 is shown below the cabinet 10.
As shown in FIGURE 2, a front wall .23 of case 10 extends outwardly from walls 11 and i112. Front wall 23 might extend only partially out from either side of the cabinet 10 so as to leave an opening in the front of the cabinet. Slots 24 are formed through the wall 23 adjacent the side walls and hinges .16 extend therethrough. Hinge 16 has a first pivoted portion 26 through which pivot pin 17 extends to attach the hinge to cover '13. The hinge has a main body portion 27 which extends through the slot -24 in the Wall 23. A slot 28 is formed in the main body portion 27 to form an upper guide arm 29 and a latch :31. The latch 31 is relatively larger and longer than arm 29. A guide pin 32 is attached to the side wall of the cabinet 10 and is received in the slot "28 when the hinge is in the closed position. A notch 33 is formed on the bottom portion of the latch relative to FIGURE 2 so as to engage the edge 34 of the wall 23 adjacent the slot 24.
FIGURE 3 illustrates the hinge with the door in the open position and it is to be noted that the door and the hinge may be moved to the right relative to the figure until the notch 33 engages the wall 23. At this point the door 13 may be pivoted to the position shown and no binding occurs between the door 13 and the adjoining cabinet 22. The notch 33 prevents the hinge and door from falling from the cabinet.
At times it may be desirable to remove the door completely and this may be accomplished as shown in FIG- URE 4. With the door in the position shown in FIG- URE 4, the hinge may be pushed upwardly to deflect the arm 29 upwardly thus freeing the notch 33 from the edge 34 of the wall 26 so as to allow the hinge and door to be removed completely from the cabinet. It is to be noted that this will not occur accidentally due to the flexure in portion 29 which will normally hold the notch 33 against the edge 34. The arm 29 is shorter than latch portion '31.
FIGURE 5 illustrates that the hinge is deformed when the door is closed which exerts a torque on the door clockwise relative to FIGURE 5. This is because of the engagement of the lip 14 with the portion 36 of the hinge to deform it as the door is closed and latched. The also causes bending in the main body portion 27 of the hinge 16 causing the latch portion 31 and portion 29 to move upwardly about the pin 32. This torque eliminates rattling of the door due to vibrations in that the hinge will be biasing the door to the open position to hold it against the latch. The latch is, of course, strong enough to hold the door closed. Although a magnetic latch is shown, it is to be realized that any conventional latch such as a spring type may be used to close the door.
The hinges on either side of the door are similar and only one is shown for purposes of illustration. The hinges may be made of any one of many (flexible materials and in one hinge an acetal copolymer such as the trade-mark products Celcon and lDelrin have been used. The bending and flexible qualities of these materials give sufiicient spring tension and strength for hinges of this type.
It is seen that this invention provides a novel hinge and although it has been described with respect to a particular embodiment thereof, it is not to be so limited, as changes and modifications may be made therein which are within the spirit and scope of the invention as defined by the appended claims.
I claim:
