BEDMAKING DEVICE Richard W. Nowels, Anaheim, Calif. Application January 22, 1959, Serial No. 788,347
8 Claims. (Cl. -320) This invention relates to household bedmaking devices and particularly to manually controlled mechanism for automatically drawing the bed covering neatly about the mattress.
The average housewife spends perhaps thirty minutes per day in making beds. A critical part of the operation is pulling the bed covers to a taut position so as to present a neat appearance. It is necessary to pull the covers from both sides of the bed, from the bottom end of the bed, and possibly also from the top end of the bed. In accomplishing this phase of the job the housewife is required to do a greatdeal of walking about the bed, and also a considerable amount of bending over. Lifting the heavy mattress in order to tuck covers under the mattress edge is the cause of many back-aches for the housewife.
Most of the time and etfort which the housewife spends in making beds is wasted, since the work is routine and does not result in the creation of new economic wealth. It is the purpose of the present invention to relieve the housewife of as much of the task as possible, by providing an inexpensive mechanical bed-making device.
In order to establish the bed covering in a taut position so as to present a well-made appearance, applicants device automatically insures proper pull from a plurality of positions.
Applicants device utilizes a plurality of pull cords removably attached to the edge of sheets, blankets,
spreads, etc. A plurality of fixed guide means are provided for the pull cords, to insure proper direction of pull and the drawing of the bed covering neatly about the mattress.
It is a primary object of the invention to provide an inexpensive, manually-actuated device for automatically positioning bed covers in a tight, tucked-in position so as to present a well-made appearance.
Another object of the invention is to provide a mechanical bed-making device which will relieve the housewife of countless hours of unproductive labor.
" An additional object of the invention is to provide a device whereby kicked-out covers may be automatically re-tucked into place by the bed occupant merely by flipping a switch.
It is another object of the invention to provide a bed covering pull-cord arrangement that will rapidly return an unmade bed covering to a tight, tucked-in position and well-made appearance.
' A further object of the invention is to provide guide means fixedly positioned on top of a bed spring near the outer edges thereof that will insure proper actuation of bed covering pull cords or wires.
Still another object of the invention is to provide manually controlled rapid operating mechanism for drawing bed covers to a neat position by means of radially disposed pull cords or wires passing through an under-bed device.
Qther objects will appear when taken in connection ice with the attached specifications and drawings, in which:
Figure 1 is a perspective diagrammatic view of the invention;
Figure 2 is a plan view of the top of the box spring taken on line 2-2 of Figure 1;
Figure 3 is a cross sectional view of a pull cord and guide tube taken on line 3-3 of Figure 2;
Figure 4 is an enlarged perspective showing the operation of the guide tube, pull cord and clamping mechamsm;
Figure 5 is a sectional view partially broken away taken on the line 5--5 of Figure 1; y
Figure 6 is an enlarged partial elevational view of the pulley drive and frictional mounting; and
Figure 7 is a schematic plan view of the top of the bed mattress and box spring showing the inventionadapted for use with sheets and blankets.
Referring now to the drawings, it will be seen that the invention has been applied to a standard bed frame 10. supported by four legs 11 and attached rollers 12.
A box spring B is conventional in all regards except with respect to a centrally disposed flared flexible tube that will be described later. 7
A mattress M is disposed on the box spring B and in this instance for a clear disclosure of the invention, the mattress M is shown covered with a conventional contour sheet 13. To simplify the disclosure, applicants novel mechanism has been shown in connection with the top sheet, although it is obvious that any bed covering or bed clothes arrangement wouldmerely require additional pull cords and guide tubes. V
A plurality of pull cords 14 are radially disposed from an under mattress control position to points adjacent the outer edge of the undersurface of the mattress. A bed covering clamp 15 is secured to the end of each of thepull cords 14 and grasps the edges of a top sheet 16 as clearly shown in Figure 2.
Surrounding each pull cord 14 is a radially disposed tubular guide17 which may be of flexible construction. The outer end of each of the guides has a grommet 18 attached thereto and the grommet 18 has a sewn or other type connection'19 with the box spring B. If an eye is used instead of a tube, the eye may be rigidly attached to the top of the box spring. 7 e
The use of a parachute-type nylon cord and plastic tubular coveriscontemplated, but other materials having similar characteristics may be provided.
A tube 20 flared at either end is disposed centrally of the box spring B in any manner desired and the plural pull cords 14 projecting from plural inner ends 21 of the tubular guides 17 pass downwardly therethrough and are: secured to a series of small pulleys 22. e t The pulleys 22 are actuated by electric motor driven gear mechanism G comprising the following elements. An electric motor 23 is controlled by a conventional spring loaded switch 24. Although the details of the. electrical circuit are not shown, motor 23 runs in only one direction, being therdirection such as to tighten the pull cords. Motor 23 has a worm. 25 that drives a worm gear 26 secured to the outer endof a horizontally disposed drive shaft 27. The drive shaft 27 is supported. in dual bearings 28 and 29 respectively and the bearings 28 and 29 are fixedly secured at wand 31 respectively to a power transmission supporting frame 32'elev'ated. slightly on plural supports or legs 33.
A worm 34 disposed intermediate the ends of drive 'shaft 27 engages a worm gear 34a pivotally supported in .to .a groupof multiplevertical short stub shafts 38-10 3 tatably mounted in a series of hubs 39 secured on the upper face'of theframe 32.
A plurality of helical compression springs 40 urge multiple friction washers 40a against the under faces of corresponding-onesof the pulleys 22. Thepulleys 22 are rotatably mounted, although frictionally held, on the-stub shafts 38 and a series of upper washers 41 and nuts 42 threadedly secure the pulleys orspools 22 operatively on the shafts 38.
Sheets 16 are sometimes provided with a peripheral series of reinforcing strips 43 for the clamps 15as'shown in Figure 4. Such reinforcing strips may alsobe provided on-blankets or other bed coverings. reinforcing strips is to prevent wear and tear on coverings, and also to show the operator where to apply'clamps when a clean covering is placed on thebed.
In-Figure 7 of the drawings, an obvious modification of applicants guided pull cords is schematically shown. In this view, the additional intermittently disposed clamping-pull cords 14 and the tubular guides 17 are shown attached to one or more blankets or quilts 44 or other bed coverings and accoutrements. Such arrangement was.
described previously in a general manner.
The operation of the unique device is simple. The frictional mountingof pulleys or spools 22 permits the bed occupant to open the bed covering, enter the bed, and arrange coverings thereafter as desired. Movement of-the occupant operates to pull the clamped cords 14 outwardly through the tubular guides 17 and thus slip the frictionally'mounted arranger pulleys 22.
When it isdesired to re-make the bed after the occupant arises, or to tighten covers while an occupant isinthe bed, springloaded switch 24 is tripped and power transmitted through the gear mechanism rotates the pulleys 22. Winding of the pull cords 14 on the pulleys 22 draws the sheet-attached clamps 15 toward the fixed ends of the tubular guides 17 and therefore draws the bed coverings to their desired tight, tucked-in, neat and unwrinkled position. The clamps 15 were manually attached to sheet 16 in the first instance. The tubes 17 (or eyes, if such are used) are so positioned as to properly guide the pull cords 14, and they also operate as stops to prevent excessive tightening of the sheets 16 or other covers.
The slip friction mounting of the pulleys 22 automatically insures substantially equal tightening of the pull cords 14, and also allows for unequal travel distances of various cords or wires to bring disarranged covers into a symmetrical position upon the bed. If the spring loaded switch is held down for an extensive period, the pulleys or spools 22 merely slip on the stub shafts 38 and no harm is done.
The present invention may be utilized with beds of any size, and also with cribs. It is not necessary that a box spring be used, for the invention can be adapted to any type of spring.
It will be noted that since the guide tubes, eyes, or other guide means are attached to the spring, the mattress may be turned over from time to time in the approved conventional manner without interference from the invention. The travel of the pull cord ends will, in general,
be from six inches inside the mattress edge to two or three feet outside, although these values are not critical.
Obviously other types of power or hand-operated tightening mechanism may be used in the same way, and my description in specific detail of the present embodiment of the invention will suggest to those skilledin the art various changes, substitutions, simplifications and other departures from the disclosure that properly lie within the scope and spirit of'the appended claims.
