Definitions

• the invention relates to a birthing chair comprising a support column and a seat part arranged thereon with a seat surface, a backrest and, to the side of the seat surface, footrests directed forwardly therefrom.
• the invention has for its object to provide, while avoiding the disadvantages mentioned above, a birthing chair of the type mentioned, in which on the one hand the risk of the child falling down is excluded or limited and on the other hand offers ergonomically favorable conditions for the midwife and the doctor.
• a substantially horizontal storage plate which is arranged on the birthing chair between a first position, in which it lies essentially completely below the seat surface, and a second position of use, in which - viewed in a vertical projection - between the footrests in front of the seat.
• the midwife's support plate serves to support the arms during obstetrics and to support the newborn after the expulsion phase. It can also be used as a storage area for a secretion bowl or discharge bowl.
• the shelf can be placed under the seat to save space. The access area for the midwife and the doctor is not restricted by the storage plate and the midwife and the doctor can work comfortably from the front while sitting.
• the storage plate is divided along a dividing line running essentially parallel to the front edge of the seat surface into two plate sections, one of which is connected to the birthing chair, while the other is movably mounted on the chair-fixed plate section in such a way that it extends into a vertical or an in the floor plan of the chair-fixed plate section falling position is adjustable.
• the shelf takes up very little space below the seat. This is particularly important in a birthing chair of the type mentioned at the beginning, in which the seat part is mounted on a support column and the seat part may be is pivotally and adjustably mounted on the column head. In this case, there is little space for stowing the shelf below the seat.
• the movable section of the storage plate is pivotally mounted on the chair-fixed plate section about an articulation axis running along the dividing line and can be pivoted between a substantially horizontal and a substantially vertical position.
• the movable plate section is simply folded down when not in use. To stow the shelf under the seat, you only need a space corresponding to the chair-fixed section of the board. On the other hand, the folded-down plate section also only requires a relatively small height, so that the seat can be adjusted far down if necessary.
• the storage plate is preferably fastened to a carriage which is displaceably guided between a pushed-in and an extended position on a support arrangement which is firmly connected to the seat part. So that the shelf is not accidentally removed from the use position under the Seat slides, the carriage is expediently lockable at least in its extended position by means of a locking device.
• This locking device can have a bolt which is movably mounted on the carriage and is pretensioned in such a way that, in the extended position of the carriage, it automatically falls into its blocking position in which it engages with the carrier arrangement.
• This bias can be done by a spring or by gravity.
• a release element is expediently provided for unlocking the bolt, which is adjustably mounted on the slide in such a way that it projects into the pivoting path of the movable plate section with an actuating end. If the movable plate section is pivoted from its horizontal position into its vertical position, it automatically actuates the disengaging element, which in turn unlocks the bolt, so that the storage plate can be inserted under the seat surface without any further manipulation.
• a support rod is provided which is articulated with its front end on the underside of the movable plate section about a pivot axis parallel to the dividing line and is guided on the slide with its rear end in a support rod guide.
• the support rod can preferably be locked in the horizontal position of the movable plate section on the support rod guide, so that the movable plate section remains in the horizontal position after being folded up.
• the support rod guide is formed by a parallel to the sliding direction of the slide, the rear end of the support rod receiving the hollow profile, at the rear end of which the bolt is arranged and in which a rail forming the release element is mounted, the rear end of the bolt controls and can be acted upon at its front end by the movable plate section.
• This solution offers the possibility that the rail can be coupled to the end of the support rod which engages in the hollow profile in such a way that the support rod moves the disengaging element into a release position when the movable plate section is pivoted, in which the latch can move into its locked position.

• the birthing chair shown schematically in FIG. 1 comprises a support column, generally designated 10, which rests on a foot part 12 and on the column head 14 of which a seat part, generally designated 16, and a transverse axis 18 are pivotably mounted.
• the seat part 16 can be pivoted about the transverse axis 18 with the aid of an only schematically indicated actuator 20.
• the column 10 contains a lifting device, not shown, with which the height of the seat part 16 can be adjusted.
• the seat part 16 comprises a seat surface 22, which is connected to a backrest 24 and from which extend laterally to the front supports 26 which carry footrests 28 and are connected to handle bars 30.
• the units consisting of the handlebars 30, the supports 26 and the footrests 28 can also each be articulated on the seat surface 22 about a vertical axis, so that they can be pivoted away to the side.
• a storage plate Beneath the seat surface 22 is a storage plate, generally designated 32, which can have, for example, a circular shape and two Sections 34 and 36, which are articulated together along a dividing line running parallel to the front edge of the seat surface 22.
• the hinge can be formed by a rigid hinge or also a foil hinge, so that the plate section 36 can be pivoted relative to the plate section 34 about a hinge axis 38 between the horizontal position represented by solid lines in FIG. 1 and a vertical position represented by dashed lines.
• the plate portion 34 is attached to a carriage generally designated 40 which is slidably supported on a support assembly 42 in the direction of the double arrow A so that the tray 32 is slidable between the extended position shown in Figure 1 and a position in which the plate portion 34 is completely inserted under the seat surface 22, as is also indicated in FIG. 1 by dashed lines. If the movable plate section 36 also hangs vertically downward in this position, the entire storage plate 32 disappears below the seat surface 22, when viewed in a vertical projection.
• the carrier arrangement 42 is fastened to the underside of the seat surface 22 via holding brackets 44 and flanges 46.
• the carriage 40 has a box section 48 which is essentially square in cross section, on the upper side of which a carrier plate 50 is fastened, which serves to support and fasten the plate section 34 of the storage plate 32.
• the plate section 34 is fastened with the aid of two screws 52 (FIG. 2), each of which is provided with a handle 54, so that they can be easily operated by hand.
• the hollow profile 48 of the carriage 40 is guided so as to be displaceable via ball rails 56 between two box girders 58 of the carrier arrangement 42.
• the carrier plate 50 engages with side walls 60 over the box girder 58, so that the slide guide formed by the box girder 58 and the ball rails 56 is completely covered.
• the front end of the carriage 40 is closed by a front wall 62, which is also formed by a bent section of the carrier plate 50.
• a flat rod 66 on the bottom thereof, which carries a bolt 68 at its rear end and is fixed with its front end to the hollow profile base by a screw 70 such that it does not extend in the longitudinal direction of the hollow profile 48 moved, but can be lifted off the bottom.
• the latch 68 can thus be adjusted between the blocking position shown in FIGS. 2 and 4, in which it falls in front of the transverse plates 72 connected to the box girders 58 when the slide 40 is extended, and a release position, which is shown in FIG. 5 and in which the latch 68 is raised in the direction of arrow B in such a way that when the slide 40 is inserted, the latch 68 slides over the transverse plates 72.
• a bar 74 which is formed by an upside-down U-profile and which extends almost over the entire length of the hollow profile 48 in, serves to lift the latch 68 from the blocking position shown in FIGS. 2 and 4 into the release position shown in FIG this extends, as shown in Figures 2 to 5.
• the U-profile rail 74 can be moved parallel to the sliding direction of the slide within the hollow profile 48 a limited distance.
• At the rear end of the U-profile rail 74 facing the bolt 68 its side legs 76 are provided with a ramp 78, with which the U-profile rail 74 can slide under the bolt 68 and raise it by the ramp effect, as shown in FIG. 5 by dashed lines Lines is shown.
• this is provided at its front end remote from the latch 68 with two bolts 80 (see FIGS. 2 and 3) which are welded to the respective outside of the U-legs 76 and through Holes in the front wall 62 of the carrier plate 50 protrude parallel to the longitudinal direction of the hollow profile 48.
• the length of the bolts 80 is selected so that when the plate section 36 is folded down, it is pushed from its horizontal into its vertical position into the hollow profile 48 and the U-profile rail 74 from the position shown in FIG. 2 to the position shown in FIG. 5 Move the position shown to the right, whereby the latch 68 is raised.
• the latch 68 automatically becomes raised so that the slide 40 can then be inserted under the seat 22 in a subsequent movement without further manipulations.
• a support rod generally designated 82, is provided, which at its front end, which is widened to form an actuating plate 84, is pivoted about an axis 86 on the underside of the movable plate section 36 (see FIG. 1).
• the guide rod 82 engages through a longitudinal gap 88 in the bottom of the hollow profile 48 and is displaceably guided on both sides of the gap 88 on the inside of the bottom with guide rollers 90 projecting laterally.
• a handle 92 is also provided on the actuating plate 84 of the guide rod 82.
• two ramps 94 are provided on both sides of the gap 88 on the inside of the profile base, over which the guide rollers 90 can run on the support rod 82.
• a recess 96 is provided between the ramp 94 and the front wall 62, which is large enough to accommodate one of the guide rollers 90.
• the operator grasps the handle 92 and swivels the plate section 36 clockwise in FIG. 1.
• the rear end of the guide rod 82 is pulled forward with the rollers 90.
• the rollers 90 run over the ramps 94 and fall into the recesses 96 between the front wall 62 and the ramps 94.
• the support rod 82 is locked so that the movable plate section 36 can no longer fall from the horizontal position into the vertical position .
• the rollers 90 take the U-shaped rail 74 with them via carriers 98 formed on the side webs 76 of the U-shaped rail 74 until it assumes the position shown in FIG. 2, in which it is disengaged from the latch 68. If the storage plate 32 is now pulled out together with the slide 40, the latch 68 can drop down as soon as it has passed the cross plates 72 on the box girders 58. So that the carriage 40 is locked against unintentional insertion.
• the operator presses the support rod 82 on the actuation plate 84 upward, so that the rear end of the guide rod 82 with the Guide rollers 90 is lifted out of the recesses 96 into the position shown in dashed lines in FIG.
• the lock is thus released and the plate section 36 can be pivoted into the vertical.
• the plate section 36 presses the U-shaped rail 74 to the right via the bolts 80, so that it lifts the latch 68 out of its locked position according to FIG.
• the carriage 40 can now be inserted under the seat surface 22.
