ZWWK Patented Oct. 30, 1 951 COMBINED HINGE, COVER SUPPORT, AND CHECK- Joseph J. Ender, Grand Rapids, Mich., assignor,

by mesne assignments, to Crampton Manufacturing Company, Holland, Mich., a corporation of Michigan Application May 21, 1945, Serial No. 595,012

' 6 Claims. 1

The main objects of this invention are:

First, to provide a cover support and check member which is effective in supporting the cover in open position and at the same time permits the cover being pulled downwardly, also serving as an effective check to control the cover in its final movement.

Second, to provide a combined hinge and cover support and check which is easily applied, is compact, and at the same time highly efficient.

Third, to provide a structure having these advantages which is attractive in appearance and not likely to become inoperative or inefiicient in use.

Objects pertaining to details and economies of the invention will definitely appear from thedescription to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation of a structure embodying the features of my invention applied to the lid of a cabinet with the lid in closed position, the cabinet and lid being sectioned on line II of Fig. 4.

Fig. 2 is a fragmentary view in section on line 2-2 of Figs. 4 and with the lid or cover in open position.

Fig. 3 is a perspective view of the unit in closed position.

Fig. 4 is a fragmentary view mainly in section on a line 4-4 of Fig. 1.

Fig. 5 is a fragmentary view partially in section on broken line 55 of Fig. 2.

Fig. 6 is a side elevation of a modified form or embodiment of my invention. v

Fig. '7 is a front elevation of the modification of Fig. 6.

In the accompanying drawing I represents a cabinet and 2 the lid or cover thereof. In Figs. 1 to 5 of the accompanying drawing the invention is illustrated as embodied in a combined hinge, cover support and check. In Figs. 6 and 7 the invention is illustrated as embodied in a combined check and support. In the embodiment of Figs. 1 to 5 thebase member 3 is in the form of a leaf hinge member and has knuckles 4 on its rear edge adapted to receive a pintle 5 engagingcomplementary knuckles 6 on the swinging hinge member I. Thebase member 3 is provided with an angularly disposed keeper arm orsupport 8 having anear 9 at its lower end perforated at I I] to receive an attaching screw II by'meansof which it is secured to the 2v inner side of the cabinet. The base member is secured to the upper edge of the cabinet wall by means of the screws I2. The keeper support has an upwardly inclined camming surface I3 of substantial length merging into the recess-like keeper I4 and also into the shoulder-like keeper I5. It will be noted by reference to Figs. 1 and 2 that thebase member 3 is an elongated platelike member of substantially uniform thickness from end to end thereof, and provides at one end thereof the knuckles 4 of the hinge joint to the hinge member I, and provides between the opposite ends thereof the spaced keepers I4 and I5 and the camming surface I3 between said keepers. This plate-like member is curvedly bodily offset at the opposite ends of the camming surface I3 relative to the general direction of the camming surface to provide said spaced keepers. This structure facilitates the ready assembly of the hinge, camming, and keeper members as a unit to the enclosure Wall, provides a relatively strong rigid structure after assembly and facilitates the ready and economical production of the same by merely stamping fiat stock material to shape.

The swinging member I is provided with holesadapted to receive attaching screws I I and I2, the screw II engaging the end of the arm I6 of the member I. The arm I6 has laterally turned ears I! carrying the pin I8 which engages the flanges of the channel shaped supporting or latching and check arm I9 which is of channel section and arranged to face rearwardly. The tensioningspring 20 is preferably formed in two coils 2I arranged on the supporting pin or pivot I8, the outer ends of the coilsbeing extended at 22 into arm-like terminals engaging the inner side of the arm I6 of the swinging hinge member. The inner ends of the coils are extended into aloop 23 which is engaged overlugs 24 turned inwardly from the edges of the flanges of the arm I9 so that the arm I9 is biased or urged under spring tension against the keeper support. Therivet 25 extending between the flanges of the arm I9 at its outer end provides a keeper engaging member for the arm. The rivet is preferably provided with a roller I25.

When the lid or cover is in its fully open position the keeperengaging member 25 engages in the recess-like keeper I4 and is urged into such engagement by the spring tension on the arm. When the lid is pulled downwardly themember 25 travels out of the keeper and additional spring thrust is imparted to the arm, this increasing as the'keeper engaging element travels alon the camming surface I3. The tension of the spring is such as to fully check the closing of the lid or cover or other closure as it approaches closed position so that manual pressure is required to fully close the closure. In the closed position thekeeper engaging element 25 engages over the shoulder-like keeper I5, thus requiring substantial force to move the closure from its closed position. This is of particular advantage when the structure is being transported as it prevents rattling, keeps the cover firmly closed and prevents any opening thereof such as might occur if the second keeper were not provided. It will be noted by reference .particularly to Figs. 1 and 2 that the surface of each of the keepers I4 and I adjacent the camming surface I3 is sloping or inclined relative to the direction of travel of the arm I9 produced.

by swinging the hinge member I, for releasing the arm from the keeper I4 when the cover is forcibly moved from an open to a closed position and for releasing the arm from the keeper I5 when the cover is forcibly moved from a closed to an open position.

In the embodiment of the invention shown in Figs. 6 and 7 the cover orclosure 26 is of the box type, being secured to thecabinet 21 by means ofseparate hinges 28. Thekeeper support 29 is substantially the same as that described in the preferred embodiment, with the exception that it is not formed as a part of the hinge. This' keeper support is provided with the recess-like keeper 36 at its upper end and a shoulder-like keeper 3| at its lower end. Thesupport 29 is secured to the inner side of the cabinet by means of thescrews 32. The swingingmember 33 is secured on the inner side of the rear wall and thecover 26 as by means of thescrews 3%. This swinging member carries apin 35 on which the combined support andcheck arm 38 is pivoted, the coiledsprin 31 being arranged on thepin 35 and provided with anchoring orthrust arms 38 engaging the member-33 and with a loop-like arm 39 connected to thearm 35. The fixed end members parts function the same as described with the exception as stated that the combination does not constitute a hinge.

Both structures are provided with means for limiting the opening movement of the closure. In the embodiment shown in Figs. 1 to 5 this stop means is in the form of shoulder-like stops I92 formed in the upper end of the keeper recess I4 to be engaged by the coacting stops I9I on the arm I9. In the embodiment shown in Figs. 6 and '7 the tongue-like stop 40 is struck out at the upper edge of thekeeper 30 to engage thetransverse pin 25 which constitutes a coacting stop.

I have illustrated and described the invention in highly practical commercial embodiments. I have not attempted to described other embodiments and adaptations as it is :believed this disclosure will enable the adaptation of my invention as may be desired.
