FIG. 7 is a fragmentary view ofa panel and mounting means therefor and including novel latch means made according to the invention.

Referring now in detail to the accompanying drawings attention is directed first to FIG. ll showing a panel, in face view, made according to the present invention.

The panel indicated in its entirety at It) includes a mesh element 12 which in the preferred form of the invention is expanded metal, of known kind, this mesh being of generally openwork construction as will be understood. The mesh is mounted in a frame 14 including perimeter frame members extending around the mesh, including; side members 14a, 14b, a bottom member 14c and a top member Md. The panel in its final condition and simplest form is, as represented in FIG. l,a simple panel including only the mesh 12 and the frame 14, without other elements or members. The specific construction of the panel is shown more fully in FIG. 2.

The mesh 12 as stated above is of expanded metal made from a solid sheet slitted in a large number of lines, each line including a large number of interrupted elements, and adjacent lines being arranged so that the line elements are staggered or offset transversely of the lines. The sheet is then expanded in directions transverse to the lines, forming strips or elements 12a interconnected by pieces 12b forming knobs, and forming opening 120, of generally diamond shape. The expanded metal mesh is of overall flat character lying generally in a plane 16 (FIG. 3), but the various elements thereof are individually displaced from that plane. For example, the strips 12a are at a slight angle to the main identifying plane 16 while the knobs 12b extend in directions transverse to the plane 16 a distance greater than the corresponding dimension of the strips 12a. The knobs 12!) identical or similar, in shape and disposition, and while the strips 12a at their point of juncture with those knobs, in pairs form a thickness similar to the knobs, but at positions along their length between the knobs assume a thickness transverse to the plane 16 considerably less than the knobs, with the result that the knobs 12b form thick elements relative to the portions of the mesh at the midpoints of the strips 12a, and they are distributed throughout the area of the mesh.

The frame members 14 are split tubular in form, preferably substantially cylindrical, as shown in FIG. 3. The cylindrical form is inexpensive and provides great strength in all directions. The frame members may be formed in a suitable and known method and shaped to provide a slot 18 running the entire length which is ofa width less than the dimension of the knobs 12b, transverse to the plane 16, and the marginal edges of the slot engage the strips 12a and by the inclusion of certain of the knobs 12b within the interior of the tubing, the mesh is retained thereby in place in the frame.

The tubing frame members may be applied to the mesh by sliding them thereon longitudinally of the frame members. The frame members are then welded together as indicated at 20 at the top of the panel or as indicated at 22 at the bottom, forming a rigid, unitary and effectively integral frame. The first three frame members, such as the bottom and two side frame members, may be individually applied and provided with mitered joints as indicated at 24 in FIG. 2 while the top frame member 14d has a butting arrangement with the side members as indicated at 26. It is within the scope of the invention however to provide the slot 18 of sufficiently great width to pass over the knobs 12b in the mesh and then crimp or compress the frame members to confine the knobs within the frame members, and in that case all of the frame members may be provided with mitered joints 24. If desired, the tubing may be made to possess a degree of springiness, biasing the slot edges constantly into engagement with the strips 120.

The cylindrical shape of the frame members provides an additional advantage and that is it enables the utilization of simple hinge means 28 which includes a circular strap element 30 encircling the corresponding frame member, such as 1419 and one or two radial fingers 32 which may be secured to the framing means 34 (FIG. 4) defining an opening 36 in which the panel is mounted. Since the frame member is substantially cylindrical, the panel swings freely in the hinge means. The panel when mounted as shown in FIG. 4 may be provided with any suitable securing means at the swinging edge, indicated diagrammatically at 38.

FIGS. 5 and 6 show a panel made according to the invention mounted in a guard position over a window or opening in a building. In this instance the panel indicated at 10 is made generally like that described above except that two side frame members 144 and 14b having extensions 40 at the bottom and 42 at the top for use in mounting the panel in position. These

extensions

40, 42 are inserted in apertures 44 in angle pieces 46 at the bottom and 48 at the top, mounted on the framing means 50 defining an opening or window 52 in a wall which the panel is utilized as a guard. These

angle pieces

46, 48 may be continuous across the window 52 or they may be individual pieces as represented in FIG. 5, to render them less conspicuous. Suitable securing means may be provided such as a latch described hereinbelow, or a padlock, for securing the panel in mounted position.

As shown in FIG. 6 the panel is mounted in guard position on the inside 54 of the wall 50 over the window having a window pane 56. This arrangement provides an added advantage in that even if the window pane is broken by a would-be intruder, he still is frustrated by the fact that the panel is mounted inwardly of the window. The inconspicuous appearance of the angle pieces enables great protection to an establishment while when the guard panel is removed, there are only small telltale indications that a guard was in place.

FIG. 7 shows a novel latch means for automatically latching the panel in place. This figure shows in large scale the portion of FIG. at the lower left comer encircled by dot-dash line 7, and the latch dog incorporated in the panel. The panel is shown at M which includes the side frame member 140 having a lower extension 40 referred to above. This extension 40 is shown extended through the aperture 44 in the angle piece 46.

Incorporated in the lower extension 40 is a latch means indicated in its entirety at 58 which includes a latch dog 60 having two arms 62, 64 at an acute angle to each other. This latch dog is mounted in the slot 18 in the tubing frame member and pivoted therein on a pin 66 mounted in the opposed wall elements of the tubing. The pin 66 is positioned at the juncture of the arms 62, 64 adjacent the outer or convex surface of the elbow between the arms, and at such a location that the latch dog assumes a position by gravity shown in full lines in FIG. 7 and here identified as a latching position. In this latching position the arm 62 extends laterally out through the slot 16 and beyond the confines of the frame member while the other arm 64 extends downwardly through the end of the frame member and substantially longitudinally thereof.

The latch dog 60 is thus arranged so that the panel can be easily inserted in place, and the latch dog, as a function of so inserting it in place, automatically moves to a position enabling that insertion, and then moves to a latching position; with the panelpoised to be inserted into position by inserting the lower extension 40 downwardly through the aperture 44, the latch dog 60 is positioned as represented in full lines in FIG. 7; as the extension 40 moves down through the aperture, the lower arm 64 passes through the aperture and then the arm 60 engages the side edge of the aperture and the dog is thrown counterclockwise to the position shown in dot-dash lines, thereby enabling the arm 64 to readily pass through the aperture; after the latch dog has completely passed through the aperture it reassumes its full line position, due to gravity, whereupon the arm 62 would engage the horizontal flange of the angle piece if an attempt were made to remove the guard, and obstruct such removal. However when the panel is to be removed by an authorized person, he merely manipulates the latch dog by engaging either of the arms and moving it to its dot-dash line position and upon moving the panel upwardly until the arm 62 enters into the aperture 44, the removal of the panel is thereupon easily performed.

It will be understood that the latch means 58 may be provided in either or both of the lower extensions 40 ofa panel as shown in FIG. 7 also it would be practical to provide opposed apertures in one of the extensions 40 to insert a padlock for use in an occasion regarded to be especially serious.
