Detailed description of the invention

Fig. 1 shows the sick bed be in without the side rail of two in position 2 having and be arranged on a side.Two side rail 2 bed length a greater part of on extend, with by making side rail enter in use location, protection can be provided to the longitudinal side of whole bed, thus preventing the personnel on bed from falling.Another longitudinal side can arrange identical side rail.Alternatively, this side can arrange the side rail that can not open, this is because personnel can leave bed from side usually.Be employed herein two independently and the identical side rail of preferred structure, realize the insurance of this side of sick bed part thus.Wherein, can only make bed indulge sideways portion's section to be protected.Like this, maybe advantageously, making when only closing described side rail in the half portion section of the head of a bed side of bed, people can be made from the bed to tumble or to fall, drop on ground or with head with then avoiding that people is lain low and first land.Further, people can move with the direction of sitting posture to bed end in bed, so that portion's section of not closing (when being namely in without position) at side rail is left the bed.Such layout, can prevent the sensation that being in irons appears in user especially.

Alternatively, also can use following side rail, this side rail comprises a column in the head end 4 of bed 1 or the region of bed end 5 respectively and covers the longitudinal side of whole bed thus.Also can at inside at least one column integrated of the head of a bed part of bed or tailstock part, make head end or bed end comprise guide for crossbeam, and in this case, can not need that there is below corresponding column turning property.One can be had in every two columns to separate spacing with the head end of bed and bed end and/or be integrated in head end and bed end.

Figure 2 illustrates the detailed structure of the side rail 2 respectively with two columns 40.Column 40 is made up of two parts, i.e. the swing column 40 on top and the lower pole 60 of bottom.Lower pole 60 comprises fixture (not shown), utilizes this fixture lower pole can be fixed on the framework of bed 1.By swinging the rotating supports 42 between column 42 and lower pole 60, swinging column 42 can at one vertically along in the plane of bed longitudinal direction orientation, swing keeping flat between orienting station and vertical position, keep flat in orienting station described, the longitudinal axis swinging column is in a longitudinal direction, and in vertical position, uprights vertical is in the plane of bed frame.Fig. 2 also illustrates two crossbeams 10 and 20, and the position of these two crossbeams is fixed, to prevent from moving up and down.

In order to bring side rail into use location (see Fig. 2) from without position (see Fig. 1), first swing column 40 upset is raised.For this reason, user is held in the gap formed between the mat 3 and swing column 40 of bed.When swinging column 40 and being in vertical position, the lock tab 71 (see Figure 10) of latching member 70 is scarfed in the corresponding lock part swinging column 40.So just prevent column from moving to backswing, followingly will to describe in detail this.

After making two columns 40 be in vertical position, upwards can lift crossbeam, thus side rail enters centre position or use location.In order to bring side rail into centre position, can the gripping groove 23 (Figure 11) of second cross beam be caught by user and second cross beam be lifted.This crossbeam can be called " second cross beam " that this second cross beam and be called another crossbeam of " first crossbeam " below all can be selected arbitrarily, wherein, owing to there is a second cross beam, might not just need also there is a first crossbeam herein.Telescopic element can axially movably be bearing in second cross beam relative to second cross beam 20, and described telescopic element is connected with the oscillating support on slide block 26, and described slide block is directed in the sliding guide piece 41 of column 40,60.The unshowned stop part of sliding guide piece 41 inside is for guaranteeing that second cross beam 20 can not be lifted to more than the maximum height shown in Fig. 3.The first end of retention wire 90 is fixed on slide block 26, and another end of described retention wire comprises drive hook 92.By lifting motion described in second cross beam 20, hook 92 is driven also to be elevated in the inside of sliding guide piece 41, until described drive hook 92 be scarfed on the free end swinging column 40 locking swing component 49 (Sperrschwenker) below time and by clamping, thus can not this to move downward again.Thus, the gravity of first crossbeam 10 and second cross beam 20 is delivered to by retention wire 90 and drives on hook 92, and swings column 40 from being delivered to by locking swing component 49 here.The stainless steel silk of retention wire 90 can be diameter be 2mm, this stainless steel silk has enough rigidity, described stainless steel silk can not be crushed in the guide recess swinging column 40, and on the other hand can when swinging column 40 and putting down reversibly 90-degree bent.In order to unclamp the kayser mediated, can complete by pressing corresponding action button 45 on column.By the mechanism of unshowned two sliding surface forms, when pressing described action button 45, locking swing component 49 is swung according to the counter clockwise direction in Figure 15 by its supporting member 91, thus unclamps and drive hook 92 to be connected with the shape of locking swing component 49 is sealed.Thus, discharge the assembly be made up of two crossbeams 10,20, thus make it be lowered into open position.In centre position, the upper edge of first crossbeam 10 in such height level, this height level be in use location corresponding first crossbeam 10 top edge height level 35% to 65% between.

When user oppositely catches the gripping area 14 of first crossbeam 10, user can lift first crossbeam 10, but now first second cross beam does not move.Gripping area 14 remains unchanged on crossbeam longitudinal direction, channel-shaped recess below crossbeam top edge, and user can be grabbed in described recess with finger tip.Be similar to second cross beam 20, first crossbeam 10 also has telescopic element 18 on two ends, and described telescopic element swingingly can support a slide block 16 respectively, this guiding in the sliding guide piece 41 of column 40 of described slide block.Slide block 16 also comprises drive face 17, and when first crossbeam 10 is lifted enough far away, the drive hook 92 of retention wire 90 just joins in described drive face.Figure 13 for the sake of clarity illustrate only drive face 17.The retention wire 90 being additionally arranged in sliding guide piece 41 illustrates to laterally offset in fig. 14.When continuing to raise first crossbeam 10 after rabbeting with drive hook 92 at slide block 16, then because the tension of retention wire 90 inside also raises first crossbeam 20.When first crossbeam 10 is lifted completely, then first crossbeam is according to Figure 13, is in its upper end position, and in this position, side rail is in use location, and now locking bolt 19 to embed in locking swing component 49 and is fixed in this position by first crossbeam 10.By operating one of described action button 45, as mentioned above, described locking swing component 49 swings, and the interlocking of corresponding locking bolt and locking swing component 49 is unclamped thus, thus when operation two action buttons 45, side rail now can come back to without in position.In the position of use, the top edge height level of the first crossbeam 10 swung on the upside of column 40 is positioned at.

Realize by operator 45 optional manner that first crossbeam 10 unclamps relative to the kayser 45 swinging column 40 as above-mentioned, described kayser also unclamps by operating handle 30.Fig. 5 illustrates the recess (Freischnitt) of first crossbeam 10.From handle 30s extraction two pull bars 36, described pull bar with its end winding support on locking bolt 19.Spring element 19a is used for making locking bolt 19 when drawing high first crossbeam 10 and corresponding locking swing component 49 enters interlocking.In order to illustrate better, the details of the handle 30 of Fig. 5 shown in Figure 6.In the both sides of handle 30, distribution arranges a gear 34.Handle 30 comprises tooth bar 32, and described tooth bar can engage with gear 34.Be in the position do not operated at shown handle 30, gear and tooth bar are not in engagement.This engagement is just started when lifting handle 30.After two teeth portion correspondingly engage, the teeth portion 34a of handle 30 makes gear 34 rotate.The teeth portion 34b of gear 34 stably engages with the tooth-strip part section 36b of tooth bar 36.Thus realize pulling pull bar 26 towards the direction of crossbeam mid point by the action of lifting handle 30.Thus, simultaneously on the two ends of first crossbeam 10, can unclamp with column 40 particularly with the kayser of its locking swing component 49.Wherein, the tooth bar 32 of handle 30 is necessary with above-mentioned engagement of the teeth portion 34a of gear 34, as shown in Figure 7, because crossbeam 10 can be made like this entering use location or can tilt without during position.The crossbeam of run-off the straight can handle side rail with more meeting human engineering, because now, crossbeam can not be locked in the inside of guide.Wherein, the direction of motion of user hands is above vertically pointing to when unclamping locking by handle 30, contrary with gravity direction in other words.Like this, when kayser unclamps, user directly can bear gravity by its hands by handle 30.When putting down crossbeam 10, a position to angular direction can be reached.For this reason, handle 30 can be triggered and automatically upwards enter its initial position do not operated, and make teeth portion 32,34 depart from engagement.

The inside that guide 41 is swinging column 40 of crossbeam 10 and 20 extends downwardly in corresponding lower pole 60.Thus it is ensured that, even if each crossbeam also can obtain good guiding without position, and in this position can by swing column 40 swing in horizontal level.Like this, as illustrated from bed inner side in fig. 8, achieve the arrangement that side rail is compact in without position.

Fig. 9 side sectional view illustrates the arrangement that side rail is compact in without position equally, wherein basically illustrates crossbeam 10,20 and swings column 40.Be positioned at outside second cross beam 20 in bed and comprise slip guard member 25, described slip guard member by cushioning plastics, such as PVC makes.When bed such as collides the doorframe in room when mobile, then come in contact with this slip guard member 25.Thus prevent the contact of such as side rail itself and doorframe.Due to crossbeam 10 and 20 and also have the matrix of column 40,60 by paint or anodised metal is made, can prevent from occurring scratch on crossbeam matrix by described slip guard member.Two crossbeams 10 guide in the identical guide 41 of column 40,60 with 20.Now its slide block 16 and 26 is mutually stacked, and this mainly also makes first crossbeam 10 therewith can move when second cross beam 20 enters centre position.Illustrate in addition, second cross beam 20 comprises the portion's section 22 before the swing column 40 that is positioned at and keeps flat.This section 22 extends to the top edge of second cross beam 20 and this section in the vertical direction has height h from the top edge of first crossbeam 10.Be in without in the side rail in position, this section 22 is positioned at and swings the top of column 40 relative to the center of rotation 42 of the supporting member of lower pole 60.

The length of the basic profile that second cross beam is extruded in the position of use, extends to corresponding swing column 40 above nearby.The end obtained thus is respectively equipped with head sections 24 (see Fig. 2), described head sections 24 points on the profile outside bed at it has the cross section identical with second cross beam 20, thus achieves the transition without boss here.Head sections 24 can make along the selection of the length of bed longitudinal direction, and described head sections in the scope of at least 80%, preferably intactly covers column 40,60 with the width of crossbeam.Because head sections is transversely positioned at before column 40,60 at bed in the position of use all the time, when moving bed and when sliding relative to surrounding structure, such as doorframe, can guarantee, to lower pole 60 and the protection swinging column 40, to prevent scraping.

Figure 10 shows the detailed view when first crossbeam 10 declines.For the sake of clarity, here lower pole is not shown.Swing column 40 and there is bearing journal 42 shown in lower pole is surrounded.Slide block 16 has drive axle journal 16a on lower end, for engaging with latching member 70.Latching member 70 utilizes supporting pin 72 to be bearing in lower pole 60 and can to rotate around axis A at this, and described supporting pin is illustrated by exploded partial view in Fig. 10.Fastener 73 additionally can partly swingingly be bearing on latching member 70 around axis B.When drivening piece 16a moves downward, apply power to fastener 73.Lean against on latching member 70 because fastener 73 swings gear on degree of freedom at it, its oscillating motion is directly delivered on latching member 70.The locking projection 71 of latching member still engaged with the stopper section swinging column 40 in this moment, and was remained in vertical position by swing column 40.Moved downward by described, locking projection 71 departs from and the gear of swing column 40 leans on, and swing column 40 can swing thus.Following leaning device makes to swing column 40 and swings to flat position.Fastener 73, relative to the movement described in latching member 70, in the adverse movement of side rail, is namely required when being closed in use location by side rail.In this case fastener 73 overcome spring force upwards (see Figure 12) swing and discharge guide 41, two slide blocks 16 and 26 can be slided into from lower pole 60 and swing column 40.Spring tappet 75 realizes the power be applied on latching member 70, locking projection 71 is snapped fit onto after the swing of swing column 40 is raised and swings in column.

Figure 11 illustrates to be fixed on and swings on column 40, in the accommodation section of pressure stage 82 cam pin 48, and described pressure stage is combined with spring 80, and this spring itself is bearing in lower pole 60.Column 40 is swung, to enter flat position by the pressure-driven of spring 80.From vertical position, spring 80 applies oscillatory forces to swing column 40 on the angle beta (see Figure 10) of 0 ° to 15 °.After this angular range, other spring ancillary method is no longer set, and also no longer needs spring ancillary method, this is because column is due to gravitation energy continuation motion.In order to limit maximal rate, be provided with buffer 84, particularly gas pressure buffer, described buffer is in parallel with spring 80 and act on pressure stage 82.

For the sake of clarity, be positioned at the pressure stage swinging column 40 inside not illustrate.This pressure stage extends to downwards near latching member 70 from operating parts 45.When operating described operating parts 45, the pressure stage of column inside moves down a segment distance.Thus, latching member 70 is to lower swing and locking projection 71 is disengaged, thus column can be swung to without position.During as supported as handle when leaving the bed by column not wishing to use side rail function, this is very useful, just needs above-mentioned functions when only having column to hold up also clamping.

Figure 16 illustrates the side view be substantially in without the side rail in position, but wherein, a swing column 40 is in the motor process swinging and pack up.The finger 9 of user shown in figure, this finger is in the top edge 22a of crossbeam 20, the portion's section 22 namely shown in Fig. 9 and to swing between column 40 crowded hinders in position.Shown in figure, when angle [alpha] is less than about 20 °, may occur squeezing wound.In other words, when this angle [alpha] is greater than about 20 ° and now the finger of user moves towards the top of angle [alpha], and after this swings column 40 and swing when declining, and points in the gap narrowed gradually pushed outwards dynamic, and there will not be and squeeze wound.Only from the angle [alpha] being less than about 20 °, the force component perpendicular to gap just arrive greatly no longer can release finger and power corresponding larger time may squeeze wound finger degree.

Figure 17 illustrates the situation similar with the side rail known by prior art.This side rail is also turnover.Here two substantially the same crossbeams are positioned on identical height level side by side, thus it is visible to be only positioned at outside crossbeam according to Figure 17.Two crossbeams have identical thickness, and described thickness is roughly equivalent to the half of column thickness.Thus, be in and be positioned at completely on two crossbeams without the column in position.In other words, without in position, two top edges of crossbeam are positioned at the below of column lower limb.Be with the difference of foregoing embodiment, do not comprise the portion's section 22 illustrated in the embodiment in fig. 17.As shown in Figure 17, also finger 9 may be clamped here.Be suitable for, critical angle of pinching α is identical.If but observe last described accompanying drawing and can see, according in the prior art of Figure 17, finger 9 to the distance of center of rotation 42 be significantly less than according to of the present invention by the distance in the embodiment of Figure 16.Because lever law can draw, when the free end swinging column 40 acts on identical load, only correspond to the sub-fraction according to the corresponding force of Figure 17 according to the clamping of Figure 16 or shear force value.Here realize described clamping force by portion's section 22 shown in Figure 9 to reduce, when side rail is in without position, described portion section is positioned at the top of the lower limb 43 swinging column 40.Here alternatively and/or additionally, corresponding portion section also can be arranged on column 40.The height of portion's section 22 should be at least swing column 40 thickness 50% to realize improving, and wherein, the vertical direction along the column be turned in bed frame plane downwards determines described thickness.The upper limit of described height can be preferably 150% of the described thickness swinging column 40.

Preferably, when subtended angle α is from 20 ° to more sharp-pointed angle, the distance d to center of rotation 42 is greater than 10cm.Alternatively, distance d2 is defined as center of rotation 42 to when subtended angle α is 20 °, and gap width is approximately the distance of the point of 1 centimetre.This gap width is equivalent to the thickness of the finger that can clamp in gap.In this case, distance d2 should be less than 12cm, to prevent clamping.

Term " vertical " or " top " and " below " are is reference design with the bed of bed frame horizontal orientation.When bed frame is in obliquity, corresponding deviation may be occurred, but this deviation can not impact to described (position) relation.
