earsir ACCESS PANEL LATCH Clifford Traut, Newport, Bly., assigner to The Higgin Ma Tit-il Application September 18, 1936. Serial No. 482,851
Claims.
My invention relates to latching devices for access panels, and particularly to concealed latches which may he actuated by a screw driver or other suitable instrument.
5 The employment of cams for latching devices has been suggested in the past.
It is my object to provide a latching device which has a latching portion, and a cano surface which cooperates with an inclined or cani sur-- l0 face of the supporting trarne or" an access panel, so that by turning the latch in one direction the panel will he securely locked in place, and hy turning the latching device in the other direction the edge of the panel on which the latch is mounted will he wedged away from the panel frame so that it may be readily reinovahle.
It is further niy object to provide a latch in which of a rotary member have correspondingly beveled cani surfaced portions mount- -0 ed in opposed directions so that one cam surfaced arni will latch in back of the access panel supporting traine while the other will, upon reverse niovernent of the latching inernher, cam the access panel out to a position where it may he readily grasped with the fingers.
Referring to the drawings in which I have illustrated a preferred type of construction, Figure l is a iront elevation of the access panel and trarne showing the position of the latch when the access panel is partially open.
Figure 2 is a horizontal sectional view showing the position of the panel with the latch closed.
Figure 3 is a sectional view as would appear along the lines 3 3 in Figure l, with the access panel moved to partially open position.
Figure fi is a sectional view showing the access panel being removed troni the panel raine.
Figure 5 is a side elevation of the latching member showing the two carn surfaced portions, one of which loclzs the latch while the other one wedges upon the panel with reversed movement of the latching ineinloer.
Figure 6 is an end elevation of the latc ber.
Figure '.7 is another view of the latch member in a slightly diierent position than that in which it is shown in llig. 5.
The access panel trarne comprises upper and F lower hars l and side bars 2 welded or secured together in an integral assembly. The metal ieces forming trarne flanged exposure edges 3 which ordinarily lie hush with the wall surface.
Inturned ribs l are set back from the face of the frame, against which ribs the access panel 5 (Cl. '292-24D is received. One side of the panel 5 is provided with a clip 5 which interloclis with the rib 4 at one side of the traine. Since the lower edge 5a of the panel seats within the lower side or the panel frame, no support is required to pre 60 vent the panel from dropping out.
Gppos'ite the side on which the clips 6 are mounted, I provide the latching arrangement which forrns the subject matter ci iny invention.
This latch arrangement comprises a housing 7 with. a carn mero er 8 therein, and a cam portion 9 formed on the adjacent trarne rio 4. The housing 7 is rnade of a strip with its upper and lower ends bent forward and Xed to the back of the panel 5, leaving its back spaced from the panel, and open sides. The cani member 8 has alined short spindle portions 8a on its back and front, respectively, one journaled Vin the housing back and the other in the panel 5 with its front end even with the front face of the panel 5 and 75 having a slot 8b into which an instrument A may be inserted as shown in Fig. 3, for turning the 8. This cam incrnloer 8 has radially diverging arms with their adjacent diverging edges beveled, one arm 9a on its front, forming cam 8G surface l0, and the other arm il on its back, forming cani surface l2. It is turned clockwise for latching; the earn surface 1U gradually wedging down in back or the rib 4. The frame cam portion 9 is a backward distension of the edge of the adjacent rib fl, located down from the axis of the cam member 8 where, upon turning this neinoer counterclockwise, the upper iront edge of the arm ll may enter the space leit in front of this portion 9 and ride its rear beveled cani 0 surface 12 up the inclined upper end thereof onto the straight front surface of the rib 4, forcing the panel 5 forward far enough for engagement of the fingers to litt the panel from the opening. 5
Having thus described my invention, what I claim as new and desire to secure by Letters Patent istl. A latch structure for use in securing a panel to the outer face of a panel frame rib, comprising a portion of said rib, having a recess in said outer face, a rotary cam member on the inner face of said panel having a portion to enter said recess and pass to the outer face of the rib to force the panel outwardly as the cam member is rotated in one direction, and a portion to pass out of said recess to the inner face of the rib and lock the panel in place as the cam member is rotated in the opposite direction.
2. A latch structure for use in securing a panel to the outer face of a panel frame rib, comprising a portion of said rib, having a recess in said outer face, a rotary cam member on the inner face of said panel, said panel having an opening through which said cam member is accessible `for rotation, and said cam member having cani faces with edges in axially spaced planes and inversely presented along said planes, one edge passing into said recess and passing therefrom to the outer face of the rib to force the panel outwardly as the cam member is rotated in one direction, and the other edge passing out of said recess to the inner face of said rib to draw the panel inwardly as the cam member is rotated in the opposite direction.
3. A latching structure for use in securing a panel in flush position with relation to the outer face of a wall frame having a rib inset from its outer face, against which the panel is to be seated, comprising a portion of said rib recessed, a rotating cam member adjacent the inner face of the panel, arranged to enter said recessed portion out of' engagement with the inner face of the rib as the cam member is rotated in` one direction, and to pass to the inner face of the rib as the cam member is rotated in the opposite direction out of' the recess, whereby the panel is forced outwardly from the frame on the ormer motion and locked-in place on the latter motion.
4; A latohing structure for use in securing a panel in flush position with relation to the outer face of a wall frame having a rib inset from its outer face, against which the panel is to be seated, comprising a portion of said rib recessed, a rotating cam member adjacent the inner face of the panel, arranged to enter said recessed portion out of engagement with the inner face of the rib as the cam member is rotated in one direction, and to pass to the inner face of the rib as the cam member is rotated in the opposite direction out of the recess, whereby the panel is forced outwardly from the frame on the former motion and locked in place on the latter motion, a stem on said cam, and a screw slot in said stem countersunk into the panel.
5. A latching structure for use in securing a panel in flush position with relation to the outer face of a wall frame having a rib inset from its outer face, against which the panel is to be seated, comprising a portion of said rib bent and leaving a recess therein and an outwardly presented cam surface in the recess, a rotating cam member adjacent the inner face of the panel, arranged to enter said recess into engagement with the cam surface oi" the rib to force the panel outwardly from the frame as the cam member is rotated in one direction, and to pass out of said recess to the inner face of the rib to lock' the panel in the frame as the cam member is rotated in the opposite direction, and means to be engaged at the outer face of the panel for rotating said cam member.
