ABSTRACT F THE DISCLOSURE An adjustable grille with collapsible bottom guard bars, including a plurality of members interconnected in lazytong fashion between vertical stiles, the bottom guard bars being interconnected at the bottom of at least one of the stiles to lie in horizontal position at the bottom of tlze lazytong members when the grille is in extended condition, and which pivots upwardly when the grille is collapsed. In the horizontal position, the guard bars prevent access to the lower portions of the lazy-tong members, and thereby prevent the forcing of the same.
This invention relates to adjustable grilles for serving as guards in connection with rear openings in trucks, doors, windows and similar openings, particularly wherein said grille is adjustable within limits to the length thereof.
The primary object of the present invention is to economically produce a grille of this kind which is adjustable while having qualities present in a xed grille, such as vertical bars mounted in conjunction with the grille structure.
A further object is to provide a grille of this kind with means to prevent tampering with the movable grille members at the bottom thereof.
Another object is to provide a collapsible grille construction of the lazy tong type which is readily extensible and collapsible and when collapsed may be positioned in a space greatly reduced from the space originally occupied when extended so that the collapsed grille may be compactly positioned immediately adjacent the side of the opening in a relative unobstructive, obscure manner.
For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:
FIGURE l is a view in front elevation of the grille in extended position,
FIGURE 2 is a similar view of the grille in collapsed condition,
FIGURE 3 is an enlarged fragmentary perspective front view of the bottom end of the grille, parts being shown broken away,
FIGURE 4 is a vertical sectional view taken on the line 4--4 of FIG. 3, parts being broken away,
FIGURE 5 is an enlarged horizontal sectional view taken on the line 5 5 of FIG. 1, and
FIGURE 6 is a similar view taken on the line 6 6 of FIG. 1.
Referring now in detail to the various views of the drawings wherein similar parts yare indicated by similar reference numerals, in FIG. 1 there is shown an adjustable grille embodying the invention and designated generally at 10. The grille comprises a framework including side frame members in the form of vertical stiles 12 and 14 and bottom end pivotal frame members in the form of pairs of straight dat metal links 16, 16 and 18, 18, pivotally connected at one end to the stiles 12 and 14, by means of pivot pins 20, the other ends of the links 16 and 18 being overlapped with overlapped ends pivotally connected by a pivot pin 22, the pivot pin 22 being disposed above the plane of the pivot pins 20 as shown in FIGS. l and 3.
Each stile 12 and 14 preferably comprises a pair of channel irons which have their side flanges directed towards each other. The channel irons 24 are held together by rivets 26 and are maintained in spaced relation by spacer sleeves 28 through which the rivets extend.
Midway in the space between the side Stiles 12 and 14, there is a central stile 30 which comprises a pair of opposed channel irons which have their side flanges directed towards each other. The channel irons 32 are held together by rivets 34 and are maintained in spaced relation by spacer sleeves 36 through which the rivets extend. At the bottom end, each channel iron 32 is formed integrally with a short guide bar 38 closely spaced from the body of the channel iron and extending from a point slightly above the bottom of the channel iron to a point thereabove and remote therefrom and being turned inwardly at the top and bottom thereof, the guide bar 38 and body of the channel iron constituting a trnckway 40 for guiding the sliding movement of the overlapped ends of the links 16 and 18.
A horizontal extensible unit indicated generally at 42 is interposed between the side stiles 12 and 14 and ex tends through the central stile 30. The unit comprises a linkage formed from a plurality of angularly disposed links 44, each link consisting of a channel-shaped bar. The links criss-cross each other as illustrated and are pivotally connected by rivets 46 at spaced intervals therealong intermediate their ends, such pivotal connections extending in horizontal lines intermediate the top and bottom ends of the stilcs 12. 14, and 30. The adjacent top and bottom ends of the links 44 are pivotally connected together by rivets 48 and 50, respectively, so that a straight line linkage results.
It will be noted that the bottom overlapped ends are normally disposed between the links 16, 16, 18, 18 when the grille is in extended position as shown in FIG. 1. This arrangement prevents tampering with, bending or otherwise damaging the grille members at the bottom thereof.
While one end of the links 44 is pivotally connected to the adjacent end of the other link of a pair, by means of the rivets 48 and Sil, the free ends of the links 44 projecting laterally into the side Stiles 12 and 14 are pivotally connected to the web portions of the channel iron 24 of the Stiles by the rivets 52.
In operation. the grillc 10 may be adjusted laterally Within limits between its normally open position as shown in FIG. 1 and its closed position as shown in FIG. 2 by pushing the side stiles 12 and 14 toward and away from each other. When they are pushed toward each other, the center stile 30 remains in a fixed position while the links 44 are caused to pivot on the pivot pins 46 whereupon the overlapped ends of the links 16 and 18 ride upwardly along the trackway provided in part by the bar portions 38, 38. The links 44 vary their angular relation to each other accordingly. The reverse action takes place upon widening the grille by pushing the side stiles 12 and 14 away from cach other.
While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended [claim] claims.
