FIG. 4 is a vertical sectional view taken through the corner assembly of FIG. 2, generally along the line IV--IV of FIG. 2.
Detailed Descriptions of the Preferred Embodiments
Referring now to the drawings in detail, reference is first made to FIG. 1, wherein the movable frame assembly that is shown in FIG. 2, is seen as comprising a pair of side frame members 11 and 12, generally disposed about 90.degree. apart, and a corner assembly 13.
The corner assembly 13 has a pair of connector arms 14, 15 extending outwardly from a corner connector portion 16, generally at 90.degree. relative to each other as shown, for facilitating telescopic receipt of the arms 14, 15, into corresponding channels or other openings 17, 18, respectively, of the frame side members 11, 12, which telescopic receipt of such arms 14, 15 is thus shown in the dotted line showing for the arms in FIG. 2.
The cross-sectional configuration for the frame side members 11, 12, may be of the roll formed or extruded U-shaped construction 20, 21 shown for example, in FIG. 1, for the frame side member 12, with the channel 18 opening upward, as shown, for receipt therein of a peripheral bead 22 for a screen 23 (see FIG. 2) therein, as shown. It will be understood that there will preferably be four such frame side members 11, 12, comprising the periphery of the movable or removable frame 10, with retaining corner assemblies 13, preferably at each of the four corners thereof.
Each arm 14, 15 of the corner assembly 13 will preferably also have a U-shaped configuration 25, opening into a channel 26, as shown in FIG. 1, including a base 27, arms 28, 30, adapted to be resiliently received in gripping telescopic relation within side members 11, 12. In the particular arrangement shown, the portions 27, 28 and 30 of the arm 15 are respectively received within zones 31, 32, 33 of frame side member 12 as shown in FIG. 1. It will be noted that the outer end of each of arm portions 27, 28 and 30 is chamfered as shown at 34.
It will also be understood that the arm 14 is constructed generally similar to that of 15, as shown, for likewise telescopic connection to the frame side member 11.
At the left end of the U-shaped opening 26 of the arm 15, and continuing into the interior 35 of the corner junction 16, is a slideway 36, as shown in FIG. 4. The slideway 36 houses therein a slide member 37, movable therein between the full line position therefor shown in FIG. 3 and the phantom line position therefor 38, also shown in FIG. 3, with the slide member 37 being of generally rectangular configuration, as shown in dotted lines in FIG. 2.
Fixedly carried on the left end of the slide member 37, and preferably unitary therewith, is a retaining protrusion 38, such that when the slide member 37 has its right-most end as shown in FIG. 3 in the phantom line position 38 illustrated in FIG. 3, the left-most end 40 of the retaining protrusion 38 is either even with the left-most end 41 of the corner connector 16, or is slightly sunken (not shown), relative thereto, such that it does not protrude outwardly thereof. When the slide member 37 is in the full line position therefor shown in FIG. 3, the retaining protrusion 38 is in the extended position shown in FIG. 3, adapted to be engaged within a recess 42 in a fixed frame member 43, preferably disposed about the movable or removable frame member 10, in which the movable or removable frame member 10 will preferably be received.
Alternatively, the slide member 37 could be of multiple-piece construction, such as in the form of a two-piece snap-in arrangement, not shown herein.
A slot 44 is provided in the slide member 37, in which a pair of locking tangs 45, 46 of a button 47 are received, in resilient engagement therewith, as shown in FIG. 3, with the button 47 having a manually engageable, slightly protruding and/or knurled outer surface 48, for engagement by preferably the thumb of a user, for sliding the slide member 37 within the slideway 36, by engaging the surface 48 of the button 47 and moving the same leftward and rightward within its guideway 50 as shown in FIG. 3.
Thus, it will be seen that the slide member 37 moves parallel with and within the slideway 36, upon movement of the button 47 within its guideway 50, also parallel therewith.
It will also be seen that the corner assembly is preferably constructed of only three components; namely, the corner connector 16 with its extending arms 14 and 15 comprising one component, with the slide member 37 comprising another component, and with the retaining button 47 comprising the third component. Alternatively, the corner assembly could be made of a fewer or greater number of components. It will also be understood that the device of the present invention may be constructed such that the components of the corner assembly are of thermoplastic construction, which lends itself to ready slidability of the sliding components within their slideways/guideways; that the corner assemblies are readily adaptable for insertion into side frame members that are of any compatible construction, such as aluminum, steel, vinyl or other appropriate materials, and which lend themselves to adaptation to various color schemes, or the like.
It will further be understood that various modifications may be made in the details of constructions, as well as in the use and operation of the components of the present invention, all within the spirit and scope of the invention as defined in the appended claims.
