7 Claims.

- 1 This invention relates generally to means whereby a normal size bedstead may be lengthcned and more particularly to a device for extending the bed rail of the standard type bedstead.

' The primary object of this invention is to provide a device which can be readily attached to a bed rail and which will thereby extend the length of said bed rail whereby the length of the entire bedstead will be increased making it possible.

to accommodate therein a person of tall stature.

Another object of the invention is to provide a simple device of the character described which will be simple and eifective in operation and economical to manufacture.

Another object of the invention is to provide a device of the character described, which when associated with a bedstead will be substantially locked in position.

A further object of the invention is to provide a device of the character described which is capable of being adjusted for compensating for variations in the dimensions of standard bed rail connections made by various manufacturers.

.Still a further object of the invention is to provide a device of the character described which will not only lengthen the bedstead, but which will `cause the rails to be firmly connected with the posts thereof, and will also be capable of being adjusted to take up wear on the connecting members to prevent the connection from being loose.

Still other objects of the invention are to provide a device of the character described which is extremely simple to install.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel features of construction, arrangement and a combination of parts hereinafter fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that various changes in the form` proportion, size andv minor details of the structure maybe made without departing from the spirit or sacrificing any of the advantages of the invention'.

'*For the purpose of facilitating an understanding of mv invention, I have illustrated in the ac-A Referring tg the drawingin lwhich the same characters of reference are employed to indicate corresponding or similar parts throughout the t several figures of the drawing:

Fig. 1 is a perspective view showing a portion of a bedstead having my new invention associated therewith and showing the manner in which the bed rail is lengthened thereby.

Fig. 2 is a side elevational View of the same on an enlarged scale with portions broken away and others in section to show the details thereof.

Fig. 3 is a fragmentary plan elevational view of the device of Fig. 2 with portions broken away and shown in section.

Fig. 4 is a fragmentary sectional View taken generally along the line 4 4 of Fig. 2 and in the indicated direction.

The reference character Ill designates generally a bedstead comprising, for illustrative purposes, a heador foot-board II having corner posts, one of which is shown at I2. A bed rail I3 is shown adapted to be connected with the post I2 and support thereon slats I4 or the like for supporting the spring and mattress (not shown). The rail I3 has its end provided with a metal blade member I5 of the conventional formation, having upper and lower hooks I5 and II, respectivey, and providing slanted slots I8 and I9. The post I2 is slotted as shown at 2G and carries pins 2I and 22 passing through the post and across the `slot 20. The blade hooks I6 and Il are adapted to cooperate with the post slot 2!! in such a manner that the slots i8 and I9 will engage the transverse pins 2l and 22 respectively and thereby hold the bedstead in assembly.

It is sometimes desirable, where the bedstead is to be used by persons who are taller than usual, that the bedstead be longer than standard. The usual bedsteads are six feet long and will accommodate tall persons uncomfortably, and hence by means of my invention it is possible to increase the length of the bedstead considerably, whereby longer mattresses and springs may be installed, thereby accommodating such persons comfortably.

I provide a device 23 which is interposed between post I2 and bed rail I3 and having means for cooperating with the pins 2I and 22 as well as the blade I5 to retain the members in assembled relationship.

The device 23 comprises a shell 24 formed as a channel-shaped member having a side wall 25, top and

bottom walls

26 and 21

land flanges

28 and 29 integrally formed with the same member' and being disposed parallel to said wall 25. Slid ably accommodated within the shell 24 there'are provided two slidable members, one of which may be termed the pin member 30 and the other of which may be termed the blade member 3|. The pin member 30 is formed having a generally channel-shaped cross-section to conform with the inner cross-section of the shell 24. There is a side wall 32, top and bottom bearing

flanges

33 and 34 and the anges 35 and 3B parallel to the wall 32. The top flange wall 33 extends only partially along the width of the pin member 30 so that when the blade I is associated therewith in a manner to be described, the space or opening 31 permits passage thereof. Upper and

lower pins

38 and 39 are riveted to the wall 32 for cooperation with the slots I8 and I9 of the blade I5. Centrally of the wall 32 is a lug 40 integrally formed therewith, said lug having a screwthreaded opening therein for accommodating therein the screw threaded end 4| of the double ended stud 42. lThe opposite end 43 of said stud is similarly associated with the lug 44 of theblade member 3|. The

pins

38 and 33 are each formed with a head portion, a reduced diameter portion 45 which will be iirmly accommodated within the slots I8 and I9, and are riveted as shown at 46 to the wall 32.

The blade member 3| is also formed of channelshaped cross-section, having the wall 41, upper ange wall 48, lower flange wall 49, upper ange 5G, lower iiange 5I. An extension of the wall is bent at 52 to form a blade 53 having upper and lower hooks 54 and 55, and upper and

lower slots

56 and 51.

When the device 23 is separate from the bedstead I0, th-e assembled blade and pin members 30 and 3| readily slide-in the shell 24 and can be shipped separately. Since there is no mechanical connection between the shell 24 and the pin andA blade members, the shells 24 can all be fabricated separately and the customer required to assemble same. Although the internal members must be made right and left the shells 24 are the same for a pair of such devices. Thus considerable saving is eiected.

The device 23 is associated with a bedstead in the following manner:

First the blade member 3| is attached to the post I2, same having the stud 42 and pin member 3Q connected therewith. Then the shell 24 is slipped over the blade and pin members with the open portion thereof facing inwardly of the bedstead and the

slots

56 and 51 adjacent the bed rail I3. Next the hooks I6 and I1 are engaged upon the

pins

38 and 39, respectively, in the process, the hook I6 passing through upper slot 53 in shell 24 and through the space or opening 31. When the device is thus assembled, the stud 42 is turned by means of a wrench, pulling the lugs 4E) and 44, and hence the members 30 and 3| together.Y assembled and substantially locked in position. t will be found that the hook I6 is moved a sufficient distance to the right as viewed in the figures such-that a major portion thereof eX- tends beyond the extent of space 31 thereby providing means for preventing withdrawal of the- It is believed that my invention, its mode "of,

The device is thus tightly- IThe described embodiment construction and assembly, and many of its advantages should be readily understood from the foregoing without further description, and it should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within thepurview of my invention as dened in the appended claims.
