As indicated in thedrawings; a berth, to which an improved guard rail cons'tructed inaccordance with this invention has'been applied, comprises a supporting framei whereo'n 'is swingably mounted a bed bottom (by means of suspension means 8, and on which bed bottom is mounted the improved guard rail 3 'for shiftin'gbetween its erect and collapsed positions as the bed bottom 1 is swung between its; open, horizontallydisposed, sleeping; position and'its closed, vertically-disposed, non-usableposition.

The supporting frame 46, preferably pr'essedn." in) 2 steel, inciude's a back'ill an'd apair of endfpanels I i The forward ed'ges of-the latter are 'formed with inwardly-disposed flanges l2 "which serve to frame the bed bottom 1 in its closed position. Brackets [3 are secured to the respective end panels I I'near the back H] to providesupport-for one of the links of the suspension mechanism 8,

to be more fully described hereinafter,- and for the support of a rubber bumper M which co-acts with the suspension mechanism 8 -to cause' horizontal disposition of thebedbottom'l.

The bed bottom 1,"likewise a unitary pressed steel construction, is formed witha bottom I5, transverse lateral sides Is and -l1,and ends IE on and withinwhic h is supported a'mattress l9 (see Fig. 1). On each of'theends 1-8 is secured brackets 20 and 2| whereto isc'onnected "apart of the suspension mechanism 8. V

The suspension mechanism 8 'herein'shown is of a construction more "fullyjset forthin copending application'serial No.51",006, filed Sept. 24, 1948. In the main it comprises a rocker arm 22, a pair of suspension links 23 and and a spacing link 25, located at each end of the berth.

Therocker arm 22 is pivoted at 26 to a trunnion plate 21 mounted onthe'inner'fa'oe of the frame end panel H. The imkie "is pivoted at 28 to the rockerarm 22 and'at 29 tothe bracket'20. The link 24 is slightly bent at 30 whereby the two parts thereof are disposed" at a slight angle to each other. The upper portion of the link 24 is pivoted at 3| to therockerarm 22 whereas the lower portion is pivoted at 32 to the bracket 2 I.

The'spacing link 25 is pivoted at 33 "to the frame bracket l3 and-at 34 to the bed bottom bracketZl.

It should be understood that the type of suspension means herein "shown and described is by no meansessential to theiguard rail 9 presently to be described. Other forms of suspension means may be used with equal facility.

The improved guard "rail 9, constructed in accordance with this 'invention, comprises aside member 35 and an end member 35 whose simultaneous shifting between the erect positions shown in Fig. 2 and the'c'ollapsedpositions shown in Fig. 4 is efiecte'dby meens' nr an'ac'tuating link 31.

The side member 35-is hinged to a pair of posts 38 and 39 welded or otherwise secured to -the outer lateral side l6 of the bed bottom l. The posts 38 and 39 are of suchaheightthatthe axis of the hinge connection 40 is located aslightly above the plane of the top of a mattress l9 (shown in dotted outline in-Figi l) supponted on the bed shown in Fig. 4, the side member 35 is permitted to fold down against the mattress l9 and whatever bedding may be on it.

The end member 36 is pivoted at 4| to the upper rail of the side member 35 and adjacent its inner end is supported by a link 42 pivoted to the bracket at 29 (the pivot for the link 23) and at 43 to the lower rail of said end member 36. Thus the end member 36, by reason of the hinge connection of the side member 35 to the bed bottom 1, is in effect supported on a pair of links and is adapted to move in its own plane rearwardly downward andforwardly upward as the side member 35 shifts between its erect and collapsed positions.

The actuating link 3?, by means of which the guard rail 9 is shifted between its erect and collapsed positions, is pivoted at 44 to the forward end of the adjacent bed-bottom spacing link 25 and at 45 intermediate the pivotal connections of the link 42 to the bracket 20 and the end'member 38. As will be noted, the forward end of the link 31 is turned up slightly to ensure the proper shifting action of the guard rail 9 when the bed bottom 1 is swung on its suspension means 8.

The operation of this improved guard rail is as follows:

When the bed bottom I is swung down from its vertically disposed, non usable position, as shown in Fig. 4, the suspension means a (which, as previously pointed out, includes the spacing link 25) causes the lateral side ll to move inwardly and upwardly as the lateral side it moves downwardly and outwardly. At the same time the spacing link 25 moves upawrdly and outward- 1157 about its pivot 33 until the lateral side i? strikes the rubber bumper IB which determines the horizontal disposition of the bed bottom I.

The corresponding upward and outward movement of the pivot 44 on the spacing link 25 shifts the actuating link 37 outwardly along the bedbottom end I 8. This outward shifting movement of the link 31 is, in turn, transmitted to the link 52 at the pivot point 45 thereby rotating the link 42 about the pivot 29 toward an erect position more or less perpendicular to the plane of the bed bottom I. This in turn moves the end member 36 of the guard rail 9 upwardly and outwardly in its own plane whereupon the side member 35 is rotated about the pivot points 42 into the erect position shown in Figs. 2 and 5.

When the bed bottom is shifted from its horizontally-disposed position toward its verticallydisposed position the inner lateral side i1 of the bed bottom tends to move downward and outwardly whereupon the downward and backward movement ofthe outer end of the link 25 causes the link 3! to swing the link 42 inwardly around its pivot 29. This inwardly swinging movement of the link 42 shifts the end member 36 of the guard rail 9 downwardly and inwardly in its own plane and, by virtue of the pivotal connection between the members 35 and 35, also causes the member 35 to swing downwardly about the pivots 4i} toward its collapsed position. An intermedi ate position of these parts during the shifting of the bed bottom toward its vertically-disposed position is indicated in Fig. 3.

Variations and modifications in the details of structure and arrangement of the parts may be resorted to within the spirit and covera e of the appended claims.
