16 Claims. (Cl. 18S-36) This invention relates to frames for iirescreens, license plates, mirrors and other articles of the type comprising longitudinal and transverse members interconnected to form a rectangular frame with slots in their opposing faces to receive the rescreen or other article to be mounted therein. v

Objects of the invention are to provide a frame which is rigid and durable in construction, which can be readily assembled and disassembled, `which is neat and attractive in appearance, and generally to improve frames of the type to which the present invention relates. i

Other objects of the invention will be evident from the following description and accompanying illustration of typical `embodiments of the invention in which `Fig. 1 is an elevation of a two-section ilrescreen;

Fig. 2 is a similar View, parts being shown in section and parts broken away;

Figs. 3 and 4 are detail sectional viewsof modifications;

Fig. 5 is a section on line 5-'5 of Fig. 3;

Fig. 6 is a section on line 6-6 of Fig. 4;

Fig. 'I is an inside face view of the longitudinal frame member of Figs. 3 and 5;

Fig. 8 is a similar view of the longitudinal'member of Figs. 1 and 2;

A Fig. 9 is a detailed sectional view of still another modiication; and

Fig. 10 is an end view of the modification of Fig. 9.

The particular embodiment of the invention shown in Figs. 1, 2 and 8 comprises longitudinal frame members I, transverse frame members 2, screen sections 3, hinge straps 4 and a tie rod 5. The longitudinal members I have slots 6 in their inner faces, these slots terminating short of the ends of the members and having enlargements 'I at their extremities. The transverse frame members 2 have slots I 0 extending throughout their vfull lengths on their inner faces. The screen sections 3 comprise longitudinally and

transverse rods

8 and 9 integrally joined together at the corners with the wire mesh of the screens mounted over these rods. The longitudinal rods 8 have extensions II and I2 at their upper and lower ends extending through openings I3 in the ends of the transverse frame members 2. Threaded on'the ends of the projecting portions II and I2 are nuts I4 and I5. The nuts I4 have tapered portions I6 telescoping inside the tubes I- to center the nuts in the tubes; and the nuts I5-have 4cylindrical portions similarly telescoping into the tubes. At the lower and upper ends' of the two central longitudinal frame members the nuts I'I telescope entirely inside the tubes with the rods 8 extending therethrough to serve as pintles for the hinge pieces 4. The two hinge 5 pieces are tied together by the rod 5 which threads into the lower hinge member and receives a nut I 8 at its upper end.

To assemble the parts 'of the embodiment shown in Figs. i, 2 and 8 the transverse frame members 10 2 are rst fitted over the top and bottom of the screeen sections with the projecting portions II and I2 of the rods 8-y projecting through the openings I3 in the ends of the transverse frame members. The longitudinal frame members I 15 are then tted over the sides of the screen sections with the ends of the transverse member 2 fitting into the enlarged ends 'I of the slot B in the 'inner faCes of the longitudinal frame members. In the case of the upper outer cor- 20 ners of the frame, where the portions II project a considerableV distance above the upper transverse members 2 the longitudinal frame members I may rst be hooked over the projecting portions I I, with the lower ends of these frame 25 members extending outwardly at an angle, the members then being simultaneously moved downwardly and swung inwardly until they reach the position shown in Figs. l and 2. Near the end of this swinging movement the screen is lifted 30 until the cross rods 9 touch the top of the inner peripheries of thetransverse tubes 2 thereby to permit the lower end of the slot 6 to pass under the lower end of rod 8.

The modication shown in Figs. 3 and 5 dif- 35 fers y'from that shown in Figs. 1, 2 and 8 in that the longitudinal frame member I has a slot extending throughout its full length as shown at 6. in Fig. '7 and in that the nut I4 is replaced by a nut I4 which has an annular groove to re- 40 ceive the end of the frame member I', with a peripheral ange 20 which covers the upper end of the slot 6. Whereas the nut I4 seats on the end of the longitudinal frame member with clearance between the nut and the end of the trans- 45 verse frame member 2, the nut I4 seats on the end of the transverse frame member 2 with cleary ance between the end of the longitudinal frame member I and thebottom of the annular groove in the nut. 50

The modification shown in Figs. 4 and 6 comprises rectangular frame members ZI and 22 instead of circular frame members as in the preceding gures. With this type of construction a ller piece 23 is preferably fitted. into the ends of 55 the longitudinal frame member 2| underneath the nut 24. The filler piece 23 preferably has the same polygonal cross section as that of the longitudinal frame member 2|.

In the modification shown in Figs. 9 and 10 the polygonal filler 23' is recessed to receive the nut 24 so that the nut does not project.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modications and equivalents which fall within the scope of the appended claims.
