' 40mins. c1. -323) My. present invention relates to bed spring lifting devices and more particularly to-the type whereby the bed spring is adapted to beswung upwardly and so maintainedthat access is had to the underside of the spring and to the floor.

.novel and improved construction, whichmis adapted to be detachably mounted onto any bed structure having an unattached spring.

Another object is to provide. a novel and im-.

proved bed spring lifter of the type described which requires a minimum of skill toinstall, a minimum of parts to be attached, and a-minimum of effort to operate. T.

A further object is to provide a novel and improved device of the character set forth, whereby there is an absence of tendency. to jumpup-or fall down when let go after the spring is shifted from horizontal rest position.

Another object of this invention is :to provide a bed spring lifter of novel and improved construction, whereby after the spring has been swung to an upward tiltedposition, it automatically is shifted into a stable upheld position.

Another object hereof is to provide' a device of the character described, the construction of use for all types of'beds. I I

A further object is to provide a novel and improved bed lifting device which is simple in con} struction, reasonably cheap to manufacture 'easy to use, and efiicient in carrying out thepurposes which is extremely compact andis adaptable for for which it is designed.

Other objects-will become manifest lowing disclosure proceeds.

Fig. 6 is a diagrammatic'slightly reduced end erally a foldable brace comprising a pair of preferably flat bars linked'at a point I6 which is near the respective ends of each to form an X-shaped structure, The other end of one of said bars which is numbered I1, is pivotally secured in any suitable manner at one side of the bed l8,

as at point I9 While the other end of the second bar which is designated by the numeral 20, is pivotally secured in any suitable manner 'at onesideof thebed spring 2l', as at point 22. Any desirable permanently or detachably secured means may be mounted along the side of the bed and along the line of the spring to provide such pivot points I!) and 22, as for instance, the

clamping means indicated generally by .the nu- -

merals

23 and 24. For a balanced construction,

a pair of suchbraces 15 are used, either near one another and centrally positioned with respect to the bed 18 as in Fig. 1, or else, one such brace "I5 at each end ofthe bed as partially shown in Figs. 2 and '7 of the drawings.

Intermediate the pivot points 16 and i9, and

. at the remote iree end of the bar ll, are lugs 25 and- 26, which extend respectively towards the other'side of the'bed I3. A coil spring 2'! is secured atone end to the extreme free end of the lug 25 at point 28, andthe other end of said spring is" secured to the remote free; end of the bar 20 at .-point 29. Another coil spring 3fi is secured at one of its ends to the extreme free end of the mg 26 at point 3|, while the other .endof said second spring is secured to point 32 on bar 20, which latter point is intermediate the pivot points lfi and 22. r

Itris'to be noted that with the bars n than colinear when the brace. 15 -is unfolded-,- the spring 30 is untensed, while spring 2 1* is in tensed condition and out of line of saidbars. These bars are urged by'the momentum imparted to them,,to a relatively crossed position as shown in Fig, 2, but the. extent of. such motion, and

their ultimate position is determined by the stop bar which may include point 3| and said stop member may be designated by the numeral 33. The set up is now in stable condition, considering that the bed spring 2| is pivotally mounted along its other edge about an axis 34.

This axis 34 may be provided at the top end of the upwardly extending members 35, mounted one onto each of the cross slats 36, which span the bed frame at its head end and front end respectively. Pivotally secured at 34, is the upper end of the normally upright arm 31 of an angle member 38, one of the latter at each arm 35,

so that the bed spring 2| may rest on the normally horizontal arms 39 of said angle members. Or else, as in Fig. '7 such axis, now designated in spaced relation connected by a detachably mounted cross bar 56 as the stop means heretofore described, namely, analogous to the stop bar 33. It is preferred that the tension spring 21 shall be of stronger construction than the tension spring 30 so that the work of opening the brace |5 shall fall primarily upon spring 21, while spring 30 for the most part, shall act as an auxiliary and primarily for the purpose of shifting the brace bars I! and 20 out of colinear position to stable position as illustrated in Fig. 1

with the bed spring 2| in raised position.

The downward action of the weight of the bed spring 2| and the mattress 51 it carries shall by the numeral 34' may be provided on a bracket 40-one such bracket for each brace |5,straddling as at 4|, or otherwise suitably mounted or secured at such side of the bed l8. In this construction the normally horizontal arms 39, of the angle members 38', extend substantially across the entire width of the bed spring 2| to support the latter, which just lies thereon, a preferable condition for all types of bed springs and especially for the box type 2|. A mattress support arm 42 is pivotally secured at one end at 43 or 43, one onto each of the arms 31 or 31' as the case may be, so that said. support arms 42 can be swung to downward position as in Fig. 3, or in mattress-supporting upward position in Figs.'2 and 4. In the embodiment of this invention as shown in end view of Fig. 7, it is evident that the

members

35 and 38 may be omitted on the slats 36 in such set-up, and if the braces l5 are far enough apart to lend proper support to the bed spring 21, then even the slats 36 may be dispensed with.

Bar is made in two parts so that its length may be adjustable by means of bolts through registerable holes 44, or by means of channel and slide construction shown at 55 adapted to be fixed by bolt 56. Slat 36 to be adjustable for beds of various widths, is provided with a channel member 45 slidable thereon at its end and adapted to be secured in necessary position. by means of bolt and nut 46. An arm indicated by the numeral 41 extends slightly spaced below the side rail 48 of the bed iii in order to prevent the slat 36 from shifting upward at any time.

When the bed spring is of the link type, attachment may be onto the pipe frame members 49 thereof, as for instance, by hook and nut 50 and a suitable clamp construction as illustrated by the numeral 24 generally. Of course, pivot point 22 may be provided by any member, as for instance, 5| directly secured to the side of the bed spring. However, in order to avoid marring by screw holes, any suitable clamp as 52 for example, may embrace the spring 2| which is a provision desirable with the box spring type. Any suitable means as the screw means 53 may be used to loosen or tighten the clamp 52 onto the bed spring 2|.

It is evident that a pair of units each comprised of a brace |5 in pivotal association at 54 with slat 36 and the member with all it carries mounted on said slat as aforedescribed, as illustrated in Fig. 2, may be adapted for any style bed. The slat 36 may rest across strips 55 in wooden bed structures illustrated in the drawings, or otherwise suitably placed or mounted to bridge the bed frame of other-bed constructions, or such units may either lie on the floor patentable novelty exist herein; reference slightly exceed or at least act to counterbalance the action of the tension springs 21 and 30 to raise said bed spring and mattress.

In operation, to lower the bed spring 2|, rod 33 isgotten hold of and constantly pushed forward by the person handling same, so that the brace components l1 and 20'become colinear and then assume an intersecting relation. This rod 33 is then let go, and "the bed spring -2| pushed downward thus stressing the coil springs 3|land 21 for readiness forthe lifting operation, which is obvious. i

This invention is capable of numerous forims and various applications without departing from the essential features herein disclosed. It 'is therefore intended and desired that the specific embodiments shown and described herein be deemed illustrative and not restrictive and that the patent shall cover whatever features of bein had to the following claims ratherthan to thi specific description herein to indicate the scope of the invention.
