7 Claims.

This invention relates generally to door latches and refers more particularly to improvements in striker plate assemblies.

It is one of the principal objecte of the ,present 5 invention to provide a striker plate assembly composed of a relatively few parts capable of being inexpensivel manufactured, assembled, and installed.

Another advantageous feature of the present 10 invention consists in the provision of a relatively small compact striker plate assembly embodying means cooperating With a latch boit to eifectively hold a closure in partially and fully closed positions.

15 A furthr -feature of the invention resicles in the provision of a striker plate assembly wherein the means set forth in the preceding paragraph not only positively prevents accidental opening movement of the closure from its partially closed 90 position, but et the same time-aflords relatively easy continued movement of the closure to its fully closed position.

The foregoing, as well asother objects, Will be made more apparent as this description proceeds,

25 especially when considered in connection With the accompanying drawing wherein:

Figure 1 is a group perspective view of two parts of the striker plate assembly forming the subject matter of this invention;

30 Figure 2 is an elevational view of a door jamb showing the striker plate assembly secured to the vertical face of the jamb;

Figure 3 is a sectional view taken substantially on the plane indicated by the line 33 of Fig- 35 ure 2;

Figure 4 is a sectional view taken substantially on the plane indicated by the line 4-4 of Figure 2;

Figure 5 is a cross sectional view showing the 40 striker plate assembly in the position the same assumes When cooperating with a latch boit to hoid the closure in partially closed position;

, Figure 6 is a similar sectional view illustrating the manner in which the striker plate assembly 45 cooperates With the latch bo1t to hold the closure in its fully closed position.

Th striker plate assembly I'0 is adapted to be secured to the vertical face of a suitable door jamb il for cooperation With a suitable latch 50 boit !2 carried by a closure l3 to eiectively hold the closure in the partially closed position shown in Figure 5 and in the fully closed position illustrated in Figure 6.

The striker plate assembly l comprises a shell I or casing M having top, side, end, and bottom Walls I5, I6, I1, and 53, respectively. As shown in Figure 4, the bottom wall I8 is adapted tobe secured to the vertical face of the jamb Il by means of fastener elementsl9 in the form of screws having the shank portions adapted to extend through openings 26 formed through the bottom wall i8 and having the usual slottedhead portions 2l accessible for manipulation through slots 22 formed in the top Wall 15 of the assembly.

The top wall i5 of the striker plate assernbly is formed or two

sections

23 and 24. The section 23 is a continuation of the outboard side wa ll 16 and is tapered to form, in eifect, a pilot for guiding the latch boit i2 into engagement With the section 24. The section 24 is in the form of a trip plate having lateral fianges 25 at opposite ends adapted to assume a position adjacent the inner surfaces of the end Walls il and pivotally connected to the end walls Il of the casing by means of the pins or rivets 26. The inboard edges 21 of the flanges 25 are shown in the several figures as being inclined at an angle corresponding to the angle of inclination of the inboard side wall i5 of the casing and are normally urged into abutting engagement With the inner surfaces et {25 the inboard side wall l6 by means of a torsion spring 23. Upon reference to Figures 3 and 6, it Will be noted that When the edges 21 on the fianges 25 of the trip plate are in abutting engagement With the inner surface of the inboard side Wall i6 of the casing, the top surface of the section 24 forme a continuation of the top surface of the section 23. With the above construction, it Will be noted that as the closure l3- is swung towards its closed position relative to the jamb Il, the boit i2 engages the section 23 of the top Wall of the striker plate and is retracted by the latter against the action of the usual rollback spring incorporated in the latch (not shovvn). Upon continued closing movement of 0 the closuie I3, the boit l2 engages the section 24' of the top wall at the outooard side of the pivots 26. The torsion spring 28 acting on the section 24 is of less strength than the roll-bac]: spring (not shown), With the result that the section 24 is swung aboutthe pivots 26 by the boit to the position shown in Figure 5. In other words, the extremity of the boit enters the casing l4 through the space occupied by the section 24 of the top wall and is prevented ircm outward movementrelative to the striker plate by means of the free edge 3B of the top wall section 23. As the closure continues to move toward its closed position, the latch boit i2 approaches the pivots 26, and the boit is carnmed outwardly With respect to the casing 14 of the striker plates until it assumes a position beyond the inboard side wall i 6 of the casing M whereupon the boit roll-back spring (notshown) returns the boit to its outermost position shown in Figure 6 of the drawing. When the boit 12 is in the position thereof shown in Figure 6 ofthe drawing, the outboard side of the bolt engages the inboard side wall l6 of the casing idand.outward movement of the closure is positively prevented until the boit i2 is retracted.

As soon as the boit l2 assumes the position shown in Figure 6, the torsion spring 28 re- 'turns the wall section 24 to its normal position the strength of the usual roll-back spring pro vided to normally urge the latch boit to its outermost position so that when the latch bo1t is engaged with the Wall section 24 at the outboard 'side of the pivots 25, this section Will be swung inwardly to the position shown in Figure 5 against the action of the spring 28. The extent "of inward movement of the wail section 24 is suficient to allow the extremity of the boit to movement of the closure I3.

xte'nd into the casing I4 and engage the edge of the wall section 23 to prevent outward Thus, from the ioregoing, it Will be observed that I have provided a striker plate assembly composed of a relativeiy few simple parts which may be inexpensively manufactured, assembld and installed. It will also be apparent that my improved striker plate assembly cooperates with a latch bo1t to efiectively ho1d a closure in partially and fully closed positions.
