FOOT-FRAME LOCK FOR FOLIDABLE BEDS.
Application filed August 24, 1921. Serial No. 494,798.
My invention relates to means, in connection with a foldable bed, for looking together in the unfolded position thereof, several of the foldable members such as the foot and bed frames, and furthermore to means for supporting one of said members while the other is being moved to or removed from the locked position.
Anobject of the invention'is to provide means of the character described which will enable the foot frame to be locked to the bed frame whereby the former may functlon to support the latter just as in an ordinary bedstea'd.
A further object is to provide means for supporting the bed frame while the latter is in the operative position and the foot frame isbeing moved to or from its position of locked engagement with said bed frame.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification; It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of thepreferred form within the scope of my invention as set forth in the claims.
Referring to said drawings:
Figure 1 is a rear end view of the bed in the open position showing the foot frame in locked position.
Figure 2 is a side view of the bed in the position shown in Figure 1, parts being removed to reduce the size of the figure.
Figure 8 is a fragmentary side view of the foot end of the bed, showing the foot frame in inoperative position.
Figure 4-. is a horizontal sectional view of the locking means and adjacent parts, the plane of section being indicated by the line 4t of Figure 1.
The bed as shown in the drawings comprises a bed frame 2 which is pivotally connected to a bracket 3 for movement about a horizontal axis 4. In the open or operative position of the bed, the frame 2 is arranged to lie horizontally disposed as shown in Figure 2, whereas in the closed or inoperative position the frame is adapted to be swung to a vertically disposed position so as to more readily adapt the bed for concealment. The end of the frame 2 adjacent the pivotal connection, is provided with a: head frame 6 which is preferably of the foldable type. Connected to the other end of the frame 2 preferably by means of links 7 and 8, is a foot frame 9, which comprises a foot board or rail 12 and integral legs 13. Due to the link connection of the frames, the former is enabled to lie perpendicularly disposed rearwardl'y of the bed frame, when the bed is open, and parallelly disposed with and spaced from the bed frame when the bed is in the inoperative or closed position. Thus in the open position the foot frame may sup port the bed in a manner similar to that obtained in the usual bedstead, and in the closed position the foot frame may overlie and rest upon the mattress and bedclothes 14: and 15.
In order that the foot frame may be locked in its perpendicular position and thereby properly support the foot end of the bed, cooperatingmeans are provided on the foot and bed frames for locking these frames against relative movement when said foot-frame is thus angularly disposed. Arranged at each end of the rear cross bar 17 of the bed frame and fixed thereto are brackets 18 and 19 in the cars 20 of each of which is slidably mounted a locking spindle or bolt 21 that is adapted when the foot frame is perpendicularly disposed, to removably engage in a suitable recess 22 formed in lugs 23 provided on the opposite sides of the foot frame. Each bolt is normally pressed to engage the associated recess by means of the spring 2 1 which e11- circles the bolt and abuts against a suitable stop thereon and against one of the bracket ears 20.
Means are provided for simultaneously drawing both bolts inwardly for the purpose of unlocking the foot frame or allowing the lugs 23 to clear the bolts when the foot frame approaches its perpendicular po sition. Pivoted to the cross bar 17 of the foot frame and mediately of its ends is a lever 27 that is connected to the free end 28 of the bolts by means of the cables 29. The connecting points of the cables on the lever are arranged on opposite sides of the latter, so that When the lever is rocked in the proper direction the bolts Will be drawn inwardly.
Means are also provided for supporting the footend of the bed frame When said frame is horizontally disposed and the foot frame is being moved to or from its locked position. Preferably pivoted to the bar 1? for movement about a h rizontal axis, is a supplemental leg 32 which is adapted to lie in a vertically disposed position in all positions of the bet. The leg 32 is shorter than the legs of the foot frame so that when the bed is open and the foot frame is perpendicularly disposed, the bed frame Will be supported by the said legs of the foot frame, Whereas When the legs of the foot frame are removed from the floor and the foot frame is being moved toward or from its perpendicular or locked position, the leg 32 will support the bed frame.
In a foldable bed, a bed frame having rail and legs, brackets fixed to the foot ends of said side rails, a cross rail connecting said brackets together, a pair of links at each side of said bed connecting said foot and bed frames together whereby said foot said brackets extendin transversely of said side rails and arranged to engage in said recesses when said foot frame is perpendicularly disposed, and hand operated means carried by said cross rail for Withdrawing both of said bolts from said recesses simul taneously.
In testimony whereof, I have hereunto set my hand at San Francisco, Calif, this 3rd day of August, 1921.
