Abstract
A method for assembling a modular siderail for attachment to a bed comprises forming a first end section to include a first connector joint, forming a second end section to include a second connector joint, and coupling the first connector joint and the second connector joint to form a skeletal structure.
Description




BACKGROUND AND SUMMARY OF THE INVENTION




This invention relates to siderails for beds and more particularly to modular siderail systems for forming skeletal structures of differing length siderails for hospital beds using various combinations of only two major skeletal components.




Health care facilities typically provide patients with beds that have siderails to prevent patients from falling out of their beds during sleep or seizures and to provide a convenient location for controls for bed positioning, nurse call buttons, speakers, television, room lighting, etc. Hospital beds are provided with siderails of differing lengths to meet the patient's needs and the hospital's aesthetic preferences. Therefore, hospital bed suppliers must have access to hospital bed siderails of varying lengths so that they can meet their customers' preferences in filling orders for beds. Hospital beds typically include siderails on each side of the bed. Often components of left and right siderails are not interchangeable requiring bed suppliers to maintain additional components in their inventories.




Hospital bed suppliers would welcome a modular siderail that includes a skeleton which can be assembled in varying lengths using a minimum number of components designed to be freely interchangeable between left siderails and right siderails.




A bed siderail system in accordance with the present invention includes a first skeletal end section having an exterior end and in interior end with a connector thereon, a second skeletal end section substantially identical to the first skeletal end section, and at least one extender having a first end with a connector thereon and a second end with a connector thereon connectable to the connector of the first and second skeletal end sections. The first and second skeletal end sections can be directly connected through the connectors on their internal ends to form a shorter length siderail, the connector of the first end section can be directly connected to one end of an extender and the connector of the second skeletal end section can be connected to the second end of the extender to form a siderail having a longer length. Multiple extender sections can be disposed between the first skeletal end section and the second skeletal end section to form even longer bed rails.




It will be appreciated therefore, that the invention is a siderail frame comprising a pair of end sections each having a cross sectional extruded shape providing an exterior and interior end such that the interior ends of the end sections are joinable to form a siderail frame. Extender sections are also provided which are joinable to the end sections to form extended siderail frames.




Features and advantages of the invention will become apparent to those skilled in the art upon consideration of the following detailed description of an illustrated embodiment exemplifying the best mode of carrying out the invention as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS




Referring to

FIG. 12

, there is illustrated a siderail


20


for attachment to a hospital bed (not shown). Siderail


20


helps to prevent a patient from falling out of the bed and also provides a convenient location for switches, controls, and speakers. Siderail


20


consists of a skeletal structure or skeleton


22


, circuitry and switches on circuit boards


24


, speaker


26


, and a molded shell


32


which partially encloses skeletal structure


22


and encloses the circuit boards


24


and speaker


26


therein. In the illustrated embodiment of siderail


20


, a caregiver-facing shell half


28


and a patient-facing shell half


30


are joined with screws


29


to form exterior shell


32


of siderail


20


. Siderail


20


is attached by screws, bolts, or other fasteners (not specifically shown but represented by lines


85


in

FIG. 12

) to first end


34


of arm mechanisms


36


which are connected at second end to the frame of the bed.




As can be seen in

FIG. 12

, illustrative skeleton


22


of siderail


20


is symmetrically formed so that caregiver-facing shell half


28


and patient-facing shell half


30


can be attached in either direction to skeleton


22


. Caregiver-facing shell half


28


and patient-facing shell half


30


at first glance appear to be substantial mirror images of each other. In actuality caregiver-facing shell half


28


and patient-facing shell half


30


differ in that patient facing shell half


30


typically includes attachment holes


80


therethrough to allow attachment of siderail


20


to arm mechanisms


36


, a speaker grill


31


behind which the diaphragm of speaker


26


is located in the assembled siderail


20


, and either more, or fewer, controls. The illustrated structure can be assembled to form a left siderail


20


(from the perspective of the patient lying supine in the bed to which siderail is attached) as shown in

FIG. 12. A

right siderail


20


R (not shown) may be formed by attaching true mirror images


28


R,


30


R (not shown) of caregiver-facing shell half


28


and patient-facing shell half


30


respectively in the opposite direction from that shown in FIG.


12


. Therefore, left and right siderails can be formed from the skeletal structure


22


reducing the need for differently configured parts to form siderails


20


for beds.




Referring to

FIGS. 1

,


2


, and


12


, a half length siderail skeleton


222


includes two identical end sections


38


oriented in opposite directions and joined together. Each end section


38


includes an exterior (or first) end


40


and an interior (or second) end


42


with interior end


42


being formed to allow end section


38


to be joined to another end section


38


(or another skeletal component as will be described later). Because skeletal structure


222


of half length siderail


20


is formed from two identical components, mirror images of a longitudinally divided shell can be attached to skeletal structure


222


in opposite orientations to form a left siderail and a right siderail.




Referring now particularly to

FIGS. 1

,


2


, and


6


-


9


, the presently preferred embodiment of end section


38


is shown. End section


38


is designed and arranged so that two identically configured end sections


38


may be joined to form a skeleton


222


of a half length siderail. End section


38


has an exterior end


40


and an interior end


42


having connectors


44


. Illustratively, end section


38


is formed by extrusion of an aluminum alloy in the shape shown in FIG.


6


. End section


38


is sliced, cut or otherwise separated from the end-shaped extrudate to have a first side


46


and a substantially parallel second side


48


defining a thickness


50


, as shown for example in FIG.


7


.




End section


38


has an upper member


52


, a middle member


54


, and a lower member


56


with these members


52


,


54


,


56


being connected at exterior end


40


and being spaced apart at interior end


42


as shown in FIG.


6


. Upper support


58


extends substantially vertically between upper member


52


and middle member


54


and lower support


60


extends at an angle from near interior end


42


of middle member


54


to near exterior end


40


of lower member


56


to increase the structural rigidity of end section


38


.




Either during or after the separation of end section


38


from the end-shaped extrudate, shoulders


66


and cheeks


64


of lap scarf end joints


62


are milled, machined, or otherwise formed adjacent to interior end


42


of upper member


52


, middle member


54


, and lower member


56


of end section


38


. Cheeks


64


extend from interior end


42


substantially parallel to sides


46


,


48


of each of upper member


52


, middle member


54


, and lower member


56


of end section


38


to shoulder


66


. Shoulder


66


extends substantially perpendicular from cheek


64


and first side


46


of each of upper member


52


, middle member


54


, and lower member


56


of end section


38


as shown, for example in FIG.


7


. Cheek


64


has a width


68


, so shoulder


66


is displaced from interior end


42


by displacement


68


. Shoulder


66


has a depth


70


, so cheek


64


is displaced from first side


46


of end section


38


by a known displacement


70


equal to one-half of thickness


50


and is thus also displaced by displacement


71


equal to displacement


70


from second side


48


of end section


38


.




Lap scarf joints


62


facilitate the joining of one end section


38


to another end section


38


, as shown, for example, in

FIG. 12

, or to another skeletal component as is described hereinafter. Since depth


70


of shoulder


66


is one-half thickness


50


of end section


38


, two end sections


38


, or an end section


38


and another skeletal component, can be joined cheek


64


to cheek


64


to form a unit having a width


74


which is the same as thickness


50


of end section


38


. Extending substantially perpendicular through cheek


64


and second side


48


is a connection hole


76


. Connection hole


76


is preferably formed during the extrusion of end-shaped extrudate but may be drilled through end section


38


after separation from end-shaped extrudate. Center


77


of connection hole


76


is displaced from interior end


42


by a displacement


180


equal to one half width


68


of cheek


64


and is also displaced from shoulder


66


by displacement


182


equal to one-half width


68


of cheek


64


.




Referring to

FIGS. 8 and 9

, when end section


38


is rotated 180 degrees about axis


9





9


, cheek


64


and shoulder


66


are positioned to form a lap scarf joint


62


with cheek


64


and shoulder


66


of another non-rotated end section


38


. During assembly of half length siderail skeleton


222


, two substantially identical end sections


38


, one rotated 180 degrees about axis


9





9


relative to the other, are joined together so that cheeks


64


and shoulders


66


on the corresponding upper members


52


, middle members


54


, and lower members


56


form three lap scarf joints


62


as shown in

FIGS. 1 and 12

. When the corresponding interior ends of each of the members


52


,


54


,


56


of each end section


38


abut shoulders


66


of the corresponding members


52


,


54


,


56


of the other end section


38


, the three connection holes


76


in each end section


38


are aligned with the corresponding connection holes


76


in the other end section


38


. A screw, bolt, dowel, rivet, or other fastener


72


extends through connection holes


76


of oppositely oriented end sections


38


to form half length siderail skeleton


222


, as shown, for example, in

FIGS. 1 and 12

.




Also located on lower member


56


of end section


38


is attachment structure


78


for attaching siderail


20


to arm mechanisms


36


of a bed. As shown, for example, in

FIG. 12

, patient-facing shell half


30


of plastic shell


32


is formed with holes


80


therethrough so that connectors (not specifically shown but indicated by lines


85


in

FIG. 12

) can pass through plastic shell


32


and through attachment holes


82


formed in attachment structure


78


in skeletal structure


22


of siderail


20


. In the illustrated embodiment, a fastener such as a screw, rivet, bolt, dowel or other device (not specifically shown but indicated by lines


85


in

FIG. 12

) is assumed to extend from central axes


84


of arm mechanisms


36


through holes


80


in plastic shell


32


and attachment holes


82


in attachment structure


78


. Center


81


of attachment hole


82


is displaced from center


77


of connection hole


76


on lower member


56


of end section


38


by a distance


86


. Distance


86


is one-half the displacement


88


between central axes


84


of arm mechanisms


36


. Thus, when two end sections


38


are joined to each other center


81


of attachment hole


82


of each end section


38


is separated from center


81


of attachment hole


82


of the joined end section


38


by a distance


90


equal to displacement


88


between central axes


84


of arm mechanisms


36


to facilitate attachment of siderail


20


to arm mechanisms


36


with fasteners (not specifically shown).




As shown in

FIGS. 3

,


4


,


5


, skeletons for siderails having lengths greater than half length siderail skeleton


222


can be formed by joining two oppositely oriented end sections


38


to one or more centrally located extender sections


92


. The presently preferred embodiment of extender section


92


is illustrated in

FIGS. 10 and 11

. Extender section


92


has an upper arm


94


, a middle arm


96


, and a lower arm


98


bidirectionally extending from a strut


100


centrally connecting upper arm


94


, lower arm


98


, and middle arm


96


. Extender section


92


has a height


102


from the bottom


104


of lower arm


98


to the top


106


of upper arm


94


which is equal to height


108


(

FIG. 6

) between top


110


of upper member


52


and bottom


112


of lower member


56


of end section


38


at interior end


42


. Middle arm


96


is displaced from upper arm


94


by displacement


114


which is equal to displacement


116


(

FIG. 6

) between middle member


54


and upper member


52


of end section


38


at interior end


42


. Middle arm


96


is displaced from lower arm


98


by displacement


118


which is equal to displacement


120


(

FIG. 6

) between middle member


54


and lower member


56


of end section


38


at interior end


42


. The equivalence of height


102


and height


108


, displacement


114


and


116


, and displacement


118


and displacement


120


respectively facilitates the joining of end section


38


to extender section


92


.




Extender section


92


is also preferably formed by extrusion of aluminum alloy. Extender section


92


is separated from extender-shaped extrudate to have a first side


122


and a second side


124


defining a thickness


126


equal to thickness


50


of end section


38


. During or after separation of extender section


92


from extender-shaped extrudate, shoulders


130


and cheeks


128


are cut, milled, machined, or otherwise formed at first end


132


of each arm


94


,


96


,


98


of extender section


92


and shoulders


136


and cheeks


134


are cut, milled, machined, or otherwise formed at second end


138


of each arm


94


,


96


,


98


of extender section


92


. Cheeks


128


and shoulders


130


on first end


132


of each arm


94


,


96


,


98


are formed by removing material from first side


122


of extender section


92


while cheeks


134


and shoulders


136


on second end


138


of each arm


94


,


96


,


98


are formed by removing material from second side


124


of extender section


92


, as shown, for example, in FIG.


11


.




Cheeks


128


extend from first end


132


substantially parallel to sides


122


,


124


of each of upper arm


94


, middle arm


96


, and lower arm


98


of extender section


92


to shoulders


130


. Shoulders


130


extend substantially perpendicular from cheeks


128


to first side


122


of each of upper arm


94


, middle arm


96


, and lower arm


98


of extender section


92


. Cheeks


128


have a width


140


, so shoulders


130


are displaced from first end


132


by displacement


140


. Shoulders


130


have a depth


142


, so cheeks


128


are displaced from first side


122


of extender section


92


by a known displacement


142


equal to one-half of thickness


126


. Cheeks


128


are also displaced by displacement


143


equal to displacement


142


from second side


124


of extender section


92


.




Similarly cheeks


134


extend from second end


138


substantially parallel to sides


122


,


124


of each of upper arm


94


, middle arm


96


, and lower arm


98


of extender section


92


to shoulders


136


. Shoulders


136


extend substantially perpendicular from cheeks


134


to second side


138


of each of upper arm


94


, middle arm


96


, and lower arm


98


of extender section


92


. Cheeks


134


have a width


144


, so shoulders


136


are displaced from second end


138


by displacement


144


. Shoulders


136


have a depth


146


, so cheeks


134


are displaced from second side


124


of extender section


92


by a known displacement


146


equal to one-half of thickness


126


. Cheeks


134


are also displaced by displacement


147


equal to displacement


146


from first side


122


of extender section


92


.




Widths


68


,


140


,


144


of cheeks


64


,


128


,


134


respectively are equal as are depths


70


,


142


,


146


of shoulders


66


,


130


,


136


to facilitate joining extender sections


92


with other extender sections


92


or end sections


38


using lap scarf joints


62


. Since depth


70


of shoulder


66


is one-half thickness


50


of end section


38


and depths


142


,


146


of shoulders


130


,


136


are one-half thickness


126


and thickness


50


is equivalent to thickness


126


, an end section


38


and another skeletal component, can be joined cheek


64


to cheek


128


,


134


to form a unit having a width


148


which is the same as thickness


50


of end section


38


and thickness


126


of extender section


92


. Likewise two extender sections


38


can be joined cheek


128


to cheek


134


to form a unit having a width


148


which is the same as thickness


50


of end section


38


and thickness


126


of extender section


92


.




Extending substantially perpendicular through cheeks


128


and first side


122


and through cheeks


134


and second side


124


are connection holes


150


. Connection holes


150


are preferably formed during the extrusion of extender-shaped extrudate but may be drilled through extender section


92


after separation from extender-shaped extrudate. Centers


152


of connection holes


150


are displaced from first and second ends


132


,


138


respectively by a displacement


154


equal to one half of widths


140


,


144


of cheeks


128


,


134


respectively. Centers


152


of connection holes


150


are also displaced from shoulders


130


,


136


respectively by displacement


156


equal to one-half of widths


140


,


144


of cheeks


128


,


134


respectively. Since displacements


154


,


156


,


180


, and


182


are all equal, connection holes


150


,


76


align when lap scarf joints


62


are formed during connection of extender sections


92


and end sections


38


.




As a result of the configuration of end section


38


and extender section


92


, extender section


92


can be connected to two oppositely facing end sections


38


or to one end section


38


and another extender section


92


to form skeletal structures of varying lengths. For example,

FIG. 3

illustrates a three-quarters length siderail skeleton


322


formed from two end sections


38


with an extender section


92


disposed therebetween while

FIG. 5

illustrates a full length siderail skeleton


422


formed from two end sections


38


with two extender sections


92


disposed therebetween.




Lower arm


98


also includes an attachment structure


158


to facilitate attaching a skeletal structure including at least one extender section


92


and two end sections


38


to arm mechanisms


36


of a bed. In the illustrated embodiment, attachment structure


158


is formed to include an attachment hole


160


extending substantially perpendicularly through extender section


92


between first side


122


and second side


124


. Center


161


of attachment hole


160


is displaced from centers


152


of connection holes


150


by a displacement


162


which is the same as displacement


86


of attachment hole


82


of end section


38


from connection hole


76


of end section


38


. Thus, when extender section


92


is connected to end section


38


the displacement


164


between center


81


of attachment hole


82


of end section


38


and center


161


of attachment hole


160


of extender section


92


is equal to the displacement


88


between central axes


84


of arm mechanisms


36


. Likewise when two extender sections


92


are connected together, the displacement


166


between center


161


of attachment hole


160


in first extender section


92


and center


161


of attachment hole


160


in second extender section


92


is equal to displacement


88


between central axes


84


of arm mechanisms


36


. Thus, siderails


20


made with the disclosed modular skeletal structure are appropriately adapted for attachment to arm mechanisms


36


regardless of the number of components forming, and overall length of, the siderail because attachment holes


82


,


160


are always equally spaced apart with a displacement


90


,


164


,


166


equal to the displacement


88


between central axes


84


of arm mechanisms


36


.




While in the illustrated and described embodiments, end section


38


and extender section


92


have been referred to as being formed from an aluminum alloy, it is to be understood that these components


38


,


92


may be formed from other metal alloys, composite materials, thermal plastics or other materials within the scope of the invention. Likewise, while extrusion is the preferred method of forming these components


38


,
