MANUAL, CONTROL FOR A MOTORIZED HOSPITAL BED Filed Oct. 50. 1961` l za 24 z5 head bed knee .Imm I INVENTOR Warren. .R .Bh-16h;

WITNESS BY MM Ala/w71 S. ATTORNEY United States Patent Oliiice 3,137,773 MANUAL CGNTRL FR A MOTORIZED HOSPITAL BEI) Warren R. Black, Grand Rapids, Mich., assigner to American Seating Company, Grand Rapids, Mich., a corporation of New Jersey Filed (let. 30, 1961, Ser. No. 148,614 6 Claims. (Cl. Zilli-5) The present invention relates to manual control for a motorized hospital bed.

The invention is particularly adapted for use in connection with hospital beds of the general type disclosed in my copending application Serial No. 108,495 filed May 8, 1961, wherein motorized mechanisms are provided for raising and lowering the head and knee sections of the bed and for raising and lowering the entire bed.

The primary objects of the invention are to provide a manual control device having an electric cord or cable which can be plugged into a receptacle in a hospital bed, by means of which the bed can be operated either by an attendant or by the bed patient himself when the latter is advisible; to provide such a device which comprises an outer casing having an upper housing in which are mounted the operating parts, and a handle depending from the housing by means of which the device may conveniently be held in the hand and operated; to provide such a device which has an escutcheon plate mounted in the open front of the casings upper housing through which plate extend three pairs of vertically spaced pushbuttons, a iirst pair for actuating mechanism for moving the beds head section up or down, a second pair for actuating mechanism to move the entire bed up or down, and a third pair for actuating mechanism to move the beds knee section up or down; to provide such a device in which the escutcheon plate bears the inscriptions Head, Bed and Knee between the respective pairs of vertically spaced pushbuttons and in which the upper and lower pushbuttons of each pair bear inscriptions denoting Up and Down respectively; to provide such a device in which six electric switches for completing circuits to energize motors for operating the bed and its several parts, are mounted inside the casings upper housing part and behind said escutcheon plate, said switches being vertically elongated and being mounted on a rear plate in side-byside relation to form a single compact row; to provide novel means for interconnecting the single row of six switches with the six pushbuttons in such a way the the pushbuttons are conveniently oriented, i.e. with an upper row of three Up pushbuttons and a lower row of three Down pushbuttons; to provide novel means whereby the Up and Down pushbuttons may be distinguished by feel as well as visually; and in general to provide such a manualcontrol for a motorized hospital bed which is convement in use, simple in construction, reasonably economical in manufacture and attractive in appearance.

. An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:

FIGURE 5 is a vertical sectional view of certain of the 3,137,773 Patented June 16, 1964 inner operating parts of the device, the plane of section being indicated at 5-5 in FIGURE 3;

FIGURE 6 is a vertical sectional view of the inner operating parts of the device, the plane of section being indicated by line 6-6 of FIGURE 5;

FIGURE 7 is a rear elevational view of a rear mounting panel of the device;

FIGURE 8 is a vertical sectional view of the device taken on lines 8 8 of FIGURES 3 and 4, with the outer casing shown fragmentarily; and

FIGURE 9 is a wiring diagram illustrating the electrical connections of the device.

Referring now in detail to this drawing, an outer casing 10 which may desirably be made of molded plastic material, has a forwardly opening upper housing part 11 in which are mounted the operating parts of the device, and a depending hollow handle part 12 communicating with the housing 11 and having an opening 13 in its lower end for the accommodation of an electric cable 14 passing from the exterior of the casing through the opening 13 and the hollow handle 12 and into the housing 11.

A dielectric rear mounting panel 15 is secured within the housing 11 as by means of screws 16 passing through openings 17 in the panel 15 and into threaded bosses 18 molded in the casing at diametrically opposite corners of the housing. An escutcheon plate 19 is secured to the rear mounting panel 15 in forwardly spaced, parallel relation thereto by means of channel brackets 20 secured to the rear plate 15 by rivets 21, and the escutcheon plate 19 is in turn secured to the channel brackets 20 by screws 22. The escutcheon plate 19 has six pushbutton openings therethrough which are arranged to provide an upper row of three Up pushbutton openings designated 23, 24 and 25, and a lower row of three Down pushbutton openings designated 26, 27 and 28.

Six elongated electric switches generally designated 30, 31, 32, 33, 34 and 35 of conventional construction are mounted on the rear mounting panel 15 in vertically elongated disposition and in side-by-side relation in a single row for compactness. As best seen in FIGURE 6, each of these switches comprises an upper angle bracket 36 secured by a rivet 37 to the panel 15 and having a forwardly extending arm 38, an operating arm 39 pivotally mounted on the forward end of arm 38, and a switch arm 40 having its upper end pivotally engaged at 41 with the arm 3S and connected to the upper end of the operating arm 39 by a tension spring 42. A lower, generally W-shaped bracket 43 has an arm 44 extending upwardly opposite switch arm 40, a rearwardly extending portion 45, a downwardly extending portion 46 secured by a rivet 47 to the rear panel 15, and a lower portion 43 extending rearwardly through an opening 49 in the rear panel. The contact points of each electric switch comprise a rivet 50 in the rear panel 15 and a point 51 on the upwardly extending arm 44 of the lower bracket 43. The switches are wired in series, current being introduced to switch 35 through a lead wire 52 (see FIGURES 3, 7 and 9), and conducted from sti/itch to switch through connecting elements 53 secured to the rear panel by means of rivets 37 and rivets 5t) previously described. Thus the switches are all in constant readiness to supply current through one or another of the lead wires 54, 55, 56, 57, 58 or 59 to complete a circuit for actuating a relay for energizing a motor in the bed to perform the operation desired. The lower rivets 21 which secure the channel brackets 20 to rear panel 15, also serve to secure a stop bar 60 to said rear panel for limiting turning movement of the switches operating arms 39.

For actuating the operating arms 39 of the six electric switches there are provided six pushbutton elements which are not aligned in a single row as are the switches but which are oriented to provide an upper row of three Up pushbuttons and a lower row of three Down pushbuttons. These six pushbutton elements are seen in rear elevation in FIGURE 5. (The reader should bear in mind that certain parts are shown as viewed from the front in FIG- URES 2 and 8 with the Head section operating elements on the left, whereas in FIGURES 5, 7 and 9 the parts are oppositely viewed from the rear with the Head section operating elements on the right.) The upper pushbutton elements'61, V62 and 63 have, respectively, upper pushbutton heads 64,Y 65 and 66 which extend through the upper pushbutton openings 23, 24 and 25 in the escutcheon plate 19', leg portions 67, 68 and 69 which extend angularly downwardly so as to pass between the escutcheon plate and the operating arms of alternating switches 31, 33l and 35, and feet portions 70, 71 and 72 which extend from the lower ends of the leg portions 67, 68 and 69 horizontally below the lower pushbutton openings and which bear against the rear surface of the escutcheon plate 19. The lower pushbutton elements 73, 74 and 75 have, respectively, lower pushbutton heads 76, 77 and 78 which extend throughv the lower pushbutton openings 26, 27 and 28 in the escutcheon plate 19, leg portions 79, 80 and 81 which extendV angularly upwardly so as to pass between the escutcheon plate and the operating arms f interveningswitches 30, 32 and 34, and feet portions' 82, 83 and 84 which extend from the upper ends of leg'portions 79, 80 and 81V horizontally above the upper pushbutton' openings and which bear against the rear surface of the escutcheon plate 19.

The outer forward ends of the upper and lower pushbutton heads bear inscriptions denoting Up and Down respectively, and the' escutcheon plate 19 bears the inscriptions Head, Bed' and Knee between the three pairs of upper and lower pushbuttons. As a further aid to distinguishing the Up pushbuttons from the Down pushbuttons, the outer forward ends of the former are convex while the outer forward ends of the latter are concave.

Thus the pushbuttons can readily be distinguished in the` dark or byv a blind patient.

Operation The tension springs 42 (see FIGURE 6) of the six electric switches normally urge the upper ends of operating arms 39 rearwardly and the lower ends of these arms 39 forwardly so as to press the pushbutton elements forwardly to inactive positions. Springs 42 also normally urge switch arms 40 rearwardly into contact with rivets 50. so that all of the switches are normally connected to lead wire 52 through the upper angle brackets 36, switch arms 40, rivets 50, connecting elements 53 and rivets 37. Lead wire 52 is connected to one pole of a source of low voltage electric current (not shown), the other pole of which source of current is connected to six relays for energizing motors to operate the Various parts of a hospital bed, the relays and motors being mounted on the bed. Lead wires 54, 55, 56, 57, 58 and 59 connect the switches 30,31, 32, 33, 34 and 35 respectively to the six relays so that a circuit can be completed through the manual control to actuate any one of said relays and thus energize a motor to move the beds head section up or down, or to move the entire bed up or down, or to move the beds knee section up or down. Inasmuch as the control of all six circuits is practically the same only one ofthem is described below in detail.

Assuming the patient'or attendant desires to lower the head section of the bed, he would press the pushbutton 76 inscribed DN beneath the inscription Head on the escutcheon plate 19, as indicated in FIGURES 6 and 9. This wouldpivot'the entire pushbutton element 73 about the line of'engagement of said elements foot 82 with the escutcheon plate, as a fulcrum. The lower end of the operating arm 39 on switch 30, being located approximately midway between the upper pushbutton opening 23 and lower pushbutton opening 26 and directly to the rear of and in contact with the angularly upwardly extending leg portion 79 of pushbutton element 73, would thus be deected rearwardly. The upper end of this operating arm would thus be moved forwardly and spring 42 would cause the switch arm 40 of switch 30 to snap forwardly past center into contact with the contact point 51 of switch 30. This would complete a circuit from lead wire 52 through the switch arms 40, rivets 50, connecting elements 53, rivets 37 and upper angle brackets 36 of the other switches, through switch arm 40, contact point 51 and lower angle bracket 46 of switch 3i), and through lead wire 54 to actuate the proper relay for energizing the motor for lowering the head section of the bed. It will be Seen that only one of the relay circuits can be completed at any one time to operate a part of the bed, which is desirable. If two or more of the pushbuttons are pressed at the same time, only the circuit nearest the lead wire 52, toward the left as seen in FIGURE 9, will be completed.

It will thus be seen that the invention provides a convenient and eicient manual control for a motorized hospital bed, and while but one specific embodiment of the invention has been herein shown and described it will be understood that numerous details thereof may be altered or omitted without departing from the spirit of the invention as defined by the following claims.
