I [In lllll HYIDRAULHC nan FRAME BACKGROUND OF THE INVENTION The invention relates to bed spring frames in general and in particular to a bed spring frame embodying means for stabilizing the movement of a bed frame member on which a bed spring is mounted An object of the invention is to provide a device of the above character which will be resilient and com fortable and absorptive of shocks incident to rough usage of the bed.
Another object ofthe invention is to provide a device of the above character which is sturdy and simple in construction. economical to manufacture and which may be made available to the public at a reasonable Cost.
These and other objects and advantages of the invention will become apparent from the following description and accompanying drawings.
To the accomplishment of the above and related objects. this invention may be embodied in the form illustrated in the accompanying drawings. attention being called to the fact. however. that the drawings are illustrative only. and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
In the drawing:
FIG. l is a top plan view of the stabilized bed frame;
FIG. 2 is a side elevation of the frame;
FIG. 3 is a bottom plan view of the frame;
FIG. 41 is a section taken on line 4-l of FIG. I;
FIG. 5 is a section taken on line 5--5 of FIG. 1;
FIG. 6 is a detail view taken on line 66 of FIG. 2;
FIG. 8 is an enlarged detail view. partly in section of a stabilizer and the manner of its attachment to the bed frame.
Referring now to the drawing in detail. the stabilized bed frame. generally indicated as It). comprises a rect' angular upper member l2 and a bottom member bl aligned with and spaced from the top member.
Secured to each of the corners of bottom member l4 are plates B6 on which are mounted hydraulic stabilizers or shock absorbers ll! of known construction. The top of each of the stabilizer pistons 20 is shaped as a ball 22 which is received in a cup 24. thus forming a ball joint. lntcgrallysecured to each cup 23 are a pair of diverging frame supports fixedly attached to adjacent eorner end portions of upper frame member l2. thus permitting the upper frame member to be displaced vcrtically with relation to the lower frame mem' her on stabilizers l8 when a downwardly directed force is applied to said upper frame member.
Mounted on each of the corners of the upper frame member l2. by means of brackets 30, are twin diverging pulleys 32.32. the bottom frame member 28' being likewise provided with twin parallel pulleys 34.34. mounted on brackets 36,36.
Extending over pulleys 32 along the longer sides of the upper frame l2 and over pulleys 3-8 of the lower frame member are cables 38,38. The portions 40,40
7 is a section taken on line 7-7 of FIG. 2 and (ill of cable 38 and portions $2.42 of cable 38 are secured to piston rods 44.44 of hydraulic stabilizers 45.45. Portions 46.46 of cable 38' are secured to piston rods 494.4%! of hydraulic stabilizers 50,50. Hydrau lie stabilizers are known, as for example those used in motor vehicles.
Extending over pulleys 32' along the shorter sides of the upper frame 12 and over pulleys 34 of the lower frame members are cables 52,52. The respective portions 54,54 of these cables are likewise secured to piston rods 48,48 of stabilizers 50,50.
There is provided a bed spring comprising a plurality of spaced flexible steel slats 54,56 arranged cross-wise to one another. The slat ends 58 are integrally secured to books 60, by means of which they are suspended on cables 38 and 52, respectively.
There is further provided a plurality of spaced cable guides 62 which are integrally secured to the upper frame member 12. The guides comprise a tubular member 64 formed with enlarged conical ends 66,66. thus permitting the cables 38,52 to freely slide through the guides and to bend when necessary, as indicated by dotted lines in FIG. 6.
It should be noted that instead of hydraulic stabilizers, there may be used compression springs.
In use when a person lies down on the bed spring. the uneven weights of the person's various body parts will cause the flexible slats 54 to pull on the respective cables 38.52. The impact of the body weight will be softened by the four stabilizers l8 and 50, 50. The same effect will. be provided when a person twists while sleeping. thus making for comfort.
I. A stabilized bed spring frame comprising a lower frame member. an upper frame having corner portions. stabilizing means mounted on said lower frame member for supporting said upper frame member and having corner portions. a flexible bed spring displaceable on said upper frame member. and means mounted on said upper and lower frame members for stabilizing said bed spring. said stabilizing means for supporting said upper frame member being hydraulic shock absorber cylinders. said stabilizing means comprising a first set of twin pulleys mounted on said corner portions of said lower frame member. cables extending over said first and second sets of twin pulleys, said cables having end portions secured to said stabilizing means. guide means for said cables slidably secured said bed spring to said cables. said guide means slidably securing said bed spring to said cables being tubular members formed with enlarged conical ends. said tubular members being fixedly secured to said upper frame members.
2. The device as claimed in claim 1, wherein said means for stabilizing said bed spring are hydraulic shock absorber cylinders.
3. The device as claimed in claim 2. wherein said guide means slidably securing said bed spring to said cables are tubular members formed with enlarged conical ends, said tubular members being fixedly secured to
