A pull-out device for a tall cup-board including a pull-out section having a bottom the pull-out device having at least a U-shaped carcass rail, a pull-out rail with which the pull-out section is connected and which has two, spaced from each other, vertical webs, and an adaptor rail for connecting the bottom of the pull-out section with the pull-out rail, the adaptor rail having an element securable to the bottom of the pull-out section and a vertical web formlockingly retainable between the vertical webs of the pull-out rail and securable against axial displacement relative to the pull-out rail.

BACKGROUND OF THE INVENTION
 1. Field of the Invention
 The present invention relates to a pull-out device for a tall cupboard and
 including a U-shaped carcass rail, a pull-out rail having two spaced
 vertical webs and, if necessary, an intermediate rail arrangeable between
 the carcass and pull-out rails, with running rollers provided on at least
 one of the rails. A section of the tall cupboard, which is connected to
 the pull-out rail is usually formed either as a box-like section or as a
 circumferentially closed frame which is formed of a profile material and
 has upper and lower horizontal bars and two vertical bars connecting the
 horizontal bars.
 2. Description of the Prior Art
 There exists numerous different embodiments of pull-out devices for tall
 cupboards. Different types of pull-out devices are described in, e.g.,
 U.S. Pat. Nos. 3,450,446 and 3,901,525; Austrian Publications A-2199/97,
 A-924/97 and A-2199/96; prospects of firms "PEKA Metall AG", "Hettlich
 International 9.34-9.35 and "Fulterer" Hochschrank-differentialrollauszug.
 In the disclosed pull-out devices, the pull-out rail has, as a rule,
 U-shaped cross-section. With regard to the arrangement of the U-shaped
 pull-out rail in the pull-out device, there exist two types of pull-out
 devices. In one type of pull-out devices, the pull-out rail is so arranged
 that its open side faces downward, with the projecting rim flanges of the
 rail cooperating with the running rollers. In the other type of a pull-out
 device, the open side of the pull-out rail faces upward. There exist two
 embodiments of a pull-out section of a tall cupboard which is attachable
 to an upwardly facing pull-out rail. According to one embodiment of a
 pull-out section, it is formed as a rectangular frame made of a profile
 material having a square cross-section, with the shelves or trays
 suspended from the vertical bars. According to another embodiment, the
 pull-out section is formed as a box with a bottom. The pull-out rail is
 attached to the bottom of the box-like section with its side flanges.
 During the attachment of the pull-out device to the tall cupboard, first,
 the carcass rail and, if used, the intermediate rail are attached to the
 bottom of the tall cupboard. The pull-out rail is secured to the bottom of
 the pull-out section of the cupboard. Usually, the pull-out rail is
 screwed to the bottom of the pull-out section. Then, the pull-out section
 of a tall cupboard, together with the pull-out rail, is inserted into the
 rail attached to the bottom of the tall cupboard. This is not only a heavy
 work but also a very cumbersome work because the sidewise projecting
 flanges of these rails should be arranged between running rollers which
 are located at different heights.
 A pull-out device for a pull-out section in which the rails are arranged
 between rolling means located at different heights is disclosed in U.S.
 Pat. No. 3,901,566. The U.S. Pat. No. 3,901,566 discloses a drawer guide
 in which the guide-forming rails are supported by balls. Such drawer
 guides with ball-supported guide rails has an advantage over the guides
 with roller-supported guide rails which consists in that the guides with
 the ball-supported guide rails cannot be disassembled or dismantled. The
 drawer guides with ball-supported guide rails include a carcass rail, a
 loading rail and, if necessary, a telescopic or differential rail and are
 formed as separate units which then are inserted into a furniture piece in
 pairs. The drawer itself is provided with side connecting braces which
 provides for attachment of the drawer to its guide. The connecting braces
 can have many different forms and consist, as a rule, of a hook member and
 a pivotal key-bolt.
 German Publication DE 197 06 246A1 discloses a telescopic pull-out device
 for a tall cupboard. The pull-out rail, to which the tall cupboard is
 attached, has, at its end side, vertically arranged screws which serve as
 adjusting screws for vertically adjusting the cupboard after the
 attachment of the pull-out device.
 An object of the present invention is to provide a pull-out device for a
 tall cupboard which would facilitate mounting a pull-out section of the
 tall cupboard on the pull-out rail.
 SUMMARY OF THE INVENTION
 This and other object of the present invention, which will become apparent
 hereinafter, are achieved by providing an adaptor rail having a vertical
 web which is formlockingly received between the vertical webs of the
 pull-out rail, without a possibility of an axial displacement relative to
 the pull-out rail. When the pull-out section is formed as a box-like
 section, the adaptor rail is formed as T-shaped rail the horizontal flange
 of which is attachable to the bottom of the box-like section. When the
 pull-out section is formed as a circumferentially closed rectangular
 frame, the lower horizontal bar of the frame functions as the vertical web
 of the adaptor rail. Providing of an adaptor rail permits to completely
 mount the pull-out device on the bottom of the tall cupboard or other
 furniture piece, including the pull-out rail. After mounting the pull-out
 device, the pull-out section having the adaptor rail attached thereto, is
 mounted on the pull-out rail.
 Advantageously, it is contemplated that the adaptor rail can pivot
 relatively to the pull-out rail about a transverse axis lying in the
 longitudinally middle region of the adaptor rail. This permits to
 vertically align the pull-out section during mounting, insuring a precise
 assembly.
 This advantage is available independent of whether the pull-out section is
 formed as a box-like section or as a circumferentially closed frame.

DESCRIPTION OF THE PREFERRED EMBODIMENT
 In the drawings described below, the same elements are shown in different
 figures at a different scale, and the same or functionally same elements
 are designated with the same reference numerals.
 A pull-out device for a tall cupboard and which is shown in FIG. 1,
 includes a U-shaped carcass rail 2, an intermediate rail 3, which is
 formed of two Z-profiles connected with crossbolts, and a pull-out rail 4.
 The three rails 2, 3 and 4 are axially displaced relative to each other in
 a conventional manner due to provision of running rollers 5, 6 and 7. In a
 pull-out device of the type described above, the running rollers, as a
 rule, are supported on the intermediate rail, i.e., the running rollers 5,
 6, 7 are supported on the intermediate rail 3. It should be pointed out
 that the present invention, which is described in detail below, is not
 limited to a three-rail pull-out device and is equally applicable to a
 pull-out device having less than three or more than three rails.
 In the pull-out device shown in FIG. 1, the pull-out rail 4 is formed of
 two U-shaped profiles 8 the vertical webs 9 of which are located adjacent
 to each other. The vertical webs 9 of the two U-shaped profiles 8 are
 spaced from each other by a distance "A". Each of the U-shaped profile 8
 has an upper flange 10 and a lower flange 11 which forms a track for the
 running rollers. The two U-shaped profiles 8 are connected with each other
 by a transverse spar 12 and form a unit. However, the transverse spar 12
 is functionally irrelevant with regard to the present invention. Instead
 of two U-shaped profiles 8, the pull-out rail 4 can be formed of single,
 upwardly opening, U-shaped profile having upper, outwardly bent-out rims.
 In its end region, the pull-out rail 4 is provided, in the upper half of
 the height H of the vertical web 9 with screwed-in threaded bolts 13 which
 are aligned with each other. Each threaded bolt 13 has, at its inner end
 surface, a journal-like projection. The pull-out rail 4 is further
 provided with a bolt 14 which connects the two vertical webs 9 and is
 arranged in the longitudinally central region of the pull-out rail 4 in
 the upper portion of the vertical webs 9. In the end regions of the
 sidewisely projecting flanges 10 of the two U-shaped profiles 8, there are
 provided threaded bores for receiving vertically extending adjusting
 screws 15.
 FIGS. 4 and 5 show side and front view of an adaptor rail 16 according to
 the present invention. The adaptor rail 16 has a T-shaped cross-section
 with a horizontal flange 17 and a vertical web 18 having a U-shaped
 profile. The outer width B of the vertical web 18 of The adaptor rail 16
 is somewhat smaller than the inner width A of the pull-out rail 4.
 Vertical elongate holes 19 are provided in the end region of the vertical
 web 18 at a distance C from an end surface of the adaptor rail 16. The
 distance C corresponds to a distance D at which the threaded bolt 13 are
 arranged in the pull-out rail 4. The rear portion 20 of the web 18 has a
 reduced height, and the lower edge 21 of the rear portion 20, in the
 longitudinally middle region of the adaptor rail 16, passes into an upper
 edge 22 of a recess 23 opening inward. The width E of the horizontal
 flange 17 of the adaptor rail 16 is somewhat smaller than the width F of a
 pull-out portion 24 of a tall cupboard and to bottom 25 of which the
 flange 17 is screwed.
 The axial lengths of the pull-out device and the adaptor rail 16 correspond
 to each other.
 For mounting the pull-out device shown in FIG. 1 in a tall cupboard, the
 carcass rail 2 is secured to a bottom 27 of a cupboard member 26, and then
 the intermediate rail 3 and the pull-out rail 4 are inserted, and the
 pull-out device becomes operative. Only the adaptor rail 16 is secured to
 the bottom 25 of the pull-out section 24 of the tall cupboard. Then, the
 pull-out section 24, together with the adaptor rail 16 screwed to the
 bottom 25, is mounted on the pull-out rail 4, with the vertical web 18 of
 the adaptor rail 16 being inserted between the vertical webs 9 of the
 pull-out rail 4, with the threaded bolts 13 having been preliminary
 withdrawn. The threaded bolts 13 have, as it has already been discussed
 previously, journal-like projections the diameter of which only slightly
 smaller than the width of the hole 19, so that these journal-like
 projections of the threaded bolts 13 can extend into the hole 19 as soon
 as the webs 9 and the web 18 overlap each other. The lower edge 21 of the
 vertical web 18 lies on the bolt 14 whereby the pull-out section 24 is
 pushed backward in the insertion direction of the pull-out device. The
 bolt 14 is located at that in the recess 23, and the vertical hole 19
 becomes aligned with the threaded bolts 13. Thereafter, the bolts 13 are
 screwed in, and their journal-like projections extend into the vertical
 hole 19, becoming formlockingly engaged therein.
 The respective shoulders of the threaded bolts 13 between the journal-like
 projections and the threaded portions of the bolts 13 abut the edges of
 the elongate hole 19. Thereby, the web 18 of the adaptor rail 16 is held
 from both 13 of the pull-out rail 4 and the vertically elongate hole 19 of
 the adaptor rail 16 permit to adjust the vertical position of the adaptor
 rail 16 with respect to the pull-out rail 4 and to fix the adaptor rail 16
 in this position. The vertical adjusting screws 15 permit to pivot the
 adaptor rail 16 and the pull-out section 24 about the axis of the bolt 14
 and align them vertically. The adaptor rail 16 is formlockingly held with
 respect to the pull-out rail 4 in the axial direction. In FIG. 8, for the
 sake of clarity, the adjusting screws 15 and the horizontal threaded bolts
 13 are represented only by their axis.
 FIG. 6 shows another embodiment of an adaptor rail 16. In FIG. 6, the
 recess 23 opens downwardly, and the web 18 has the same width along its
 entire height G. The insertion of this adaptor rail 16 into the pull-out
 device requires a greater care and attention because during the insertion,
 care should be taken that the recess I, i.e., the recess 23 overlaps the
 bolt 14, whereas with the use of the adaptor rail 16 shown in FIG. 4, no
 specific measures for insuring that the recess 23 coincides with the bolt
 14, are necessary. The shorter rear portion 20 extend almost over a half
 of the axial length of the adaptor rail 16 shown in FIG. 4.
 With the pull-out devices for a tall cupboard of a type described above,
 guides 28 are usually provided on the cupboard ceiling. These guides have
 a conventional construction and therefore, would not be described in
 detail. FIG. 9 shows a tall cupboard 1 with a pulled-out section 24 and a
 pull-out device shown in FIG. 1 and secured to the bottom 27 of the
 cupboard. The pull-out device includes an adaptor rail 16.
 It is within the scope of the invention to form the adaptor rail of several
 parts and connect them together with crossbolts and other connection
 means. In the embodiments of the adaptor rail shown in the drawings, the
 adaptor rail is formed as a one-piece part. As discussed above, the width
 B of the vertical web 18 of the adaptor rail 16 is smaller than the width
 A of the pull-out rail 4. To compensate for this width difference, the
 vertical webs 9 of the pull-out rail 4 can be provided with downward
 extending indentations, or these vertical webs 9 can be formed as
 free-stamped fish plates bent-out inward toward each other and acting as a
 plate spring, with the vertical web 18 of the adaptor rail 16 being
 received between the so-formed vertical webs 9. The front formlocking
 connection between the pull-out rail 4 and the adaptor rail 16 is insured
 by the threaded bolt 13 and the vertical elongate hole 19 formed in the
 web 18 of the adaptor rail 16. Instead of threaded bolts 13, spring-biased
 locking elements can be used which can be built-in in the vertical web 18
 because the width B of the web 18 provides sufficient space for such
 locking elements and their parts. These locking elements can be so formed
 that they can be displaced in a horizontal plane or can pivot about a
 horizontal axis, a necessary condition being that the locking elements
 cooperate with the vertical holes. In this case, the vertical holes are
 formed in the vertical webs of the pull-out rail 4.
 A pull-out device, which is shown in FIGS. 10-15, likewise has a U-shaped
 carcass rail 2, intermediate rail 3, which is formed of two Z-profiles
 connected with crossbolts, and a pull-out rail 4. The three rails 2, 3 and
 4 are axially displaced relative to each other in a conventional manner
 due to provision of running rollers 5, 6 and 7. In a pull-out device of
 the type described above, the running rollers, as a rule, are supported on
 the intermediate rail, i.e., the running rollers 5, 6, 7 are supported on
 the intermediate rail 3. It should be pointed out that the present
 invention, which is described in detail below, is not limited to a
 three-rail pull-out device and is equally applicable to a pull-out device
 having less than three or more than three rails.
 The pull-out rail 4 is formed of two U-shaped profiles 8 the vertical webs
 9 of which are located adjacent to each other. The vertical webs 9 of the
 two U-shaped profiles 8 are spaced from each other by a distance "A". Each
 of the U-shaped profile 8 has an upper flange 10 and a lower flange 11
 which forms a track for the running rollers. The two U-shaped profiles 8
 are connected with each other by a transverse spar 12 and form a unit.
 However, the transverse spar 12 is functionally irrelevant with regard to
 the present invention. Instead of two U-shaped profiles 8, the pull-out
 rail 4 can be formed of a single, upwardly opening, U-shaped profile
 having upper, outwardly bent-out rims.
 In its end region, the pull-out rail 4 is provided, in the upper half of
 the height H of the vertical web 9 with screwed-in threaded bolts 13.
 Further, in this embodiment of a pull-out device, there is provided a stop
 30 which limit the pull-out path of the pull-out rail 4 relative to the
 intermediate rail 3.
 In the embodiment of a pull-out device shown in FIGS. 10-15, a threaded
 bore is provided in the transverse spar 12 for receiving an adjusting
 screw 15 provided with a knurled disc 31 for manually operating the screw
 15. At the end surface of the adjusting screw 15, there is provided a
 bearing disc 32 the diameter of which is somewhat larger than the diameter
 of the screw 15. A vertical elongate hole is provided in the screw 15 in
 which a spring-biased indexing bolt 33 is arranged. The indexing bolt 33
 projects above the bearing disc 32. With a disc 34, the indexing bolt 33
 can be pulled downward and retained in its downward position. The disc 34
 is so formed that it projects beyond the knurled disc 31 only on two
 diametrically opposite sides. Further, in the longitudinally middle region
 of the pull-out rail 4, there are provided two pairs of pressure pads 35
 which extend substantially horizontally. The pressure pads 35 can either
 be welded to the vertical webs 9 or be formed by free-stamped fishplates.
 In the embodiment shown in the drawings, the pads are bent along their
 entire length. It is possible to make the pads 35 rectilinear and
 extending parallel to each other, with only their portions, which are
 adjacent to the end surface of the pull-out rail 4 having a funnel shape.
 FIGS. 14 and 15 show side and front views of the adaptor rail 16 of the
 modified embodiment of the pull-out device. The adaptor rail 16 has a
 T-shaped cross section with a horizontal flange 17 and a vertical web 18
 having a U-shaped cross section. The width B of the vertical web 18 is
 slightly smaller than the width A of the pull-out rail. The width E of the
 horizontal flange 17 is somewhat smaller than the width F of the pull-out
 section 24 of the tall cupboard and to bottom 25 of which the flange 17 is
 screwed. In the longitudinally middle region of the adaptor rail 16, only
 a bolt 36 is provided which extends through the U-shaped vertical web 18.
 The diameter of the bolt 36 is somewhat smaller than the distance G
 between the pad 35. The bottom of the web 18 has, in its front region, a
 recessed groove 37 and a fishplate 38 located adjacent to the groove 37.
 The fishplate 38 has a downwardly projecting section bent at a right
 angle.
 The axial lengths of the pull-out device and the adaptor rail corresponds
 to each other.
 For mounting the pull-out device shown in FIG. 10 in a tall cupboard, the
 carcass rail 2 is secured to a bottom 27 of a cupboard member 26, and then
 the intermediate rail 3 and the pull-out rail 4 are inserted, and the
 pull-out device becomes operative. Only the adaptor rail 16 is secured to
 the bottom 25 of the pull-out section 24 of the tall cupboard. Then, the
 pull-out section 24, together with the adaptor rail 16 screwed to the
 bottom 25, is mounted on the pull-out rail 4, with the vertical web 18 of
 the adaptor rail 16 being inserted between the vertical webs 9 of the
 pull-out device 4, with the threaded bolts 13 having been preliminary
 withdrawn. The horizontal flange 17 of the adaptor rail 16 lies on the
 upper flanges 10 of the pull-out rail 4, whereas the pull-out section 24
 is pushed rearwardly in the insertion direction of the pull-out device.
 The indexing bolt 33 is pressed downwardly by the web 18 which lies on it.
 With this, the bolt 36 is pushed between the pads 35. As soon as the
 recess 37 covers the spring-biased indexing bolt 33, it springs upward and
 becomes form lockingly engaged in the recessed groove 37. In addition, the
 front end of the fishplate 38 engages from beneath the edge of the bearing
 disc 32. The adjusting screw 15 provides for adjustment of the adaptor
 rail 16 in the vertical direction, and the threaded bolts 13 provide for
 adjustment of the adaptor rail 16 in the horizontal direction.
 The adjusting screw 15 provides for pivoting of the pull-out section 24 or
 of the adaptor rail 16 about the axis of the bolt 36. The adaptor rail 16
 is formlockingly retained, in a horizontal direction, relative to the
 pull-out rail 4 by the indexing bolt 33 against being lifted up by
 cooperation of the bearing disc 32 with the fishplate 38.
 In the embodiment shown in the drawings (FIG. 14), the adaptor rail is
 formed as a one-piece member. However, it is within the scope of the
 invention to form the adaptor rail of several parts and connect them
 together with crossbolts and other connection means. In the embodiments of
 the adaptor rail shown in the drawings, the adaptor rail is formed as a
 one-piece part. As discussed above, the width B of the vertical web 18 of
 the adaptor rail 16 is smaller than the width A of the pull-out rail 4. To
 compensate for this width difference, the vertical webs 9 of the pull-out
 rail 4 can be provided with downward extending indentations, or these
 vertical webs 9 can be formed as free-stamped fishplates bent-out inward
 toward each other and acting as a plate spring, with the vertical web 18
 of the adaptor rail 16 being received between the so-formed vertical webs
 9. The front formlocking connection between the pull-out rail 4 and the
 adaptor rail 16 is insured by cooperation of the recessed groove 37 with
 the indexing bolt 33 and by cooperation of the bearing disc 32 with the
 fishplate 38.
 The adaptor rail 16 supports the pull-out section 24 of the tall cupboard
 1, which has a box-like shape (FIG. 1) in a manner shown and described
 above. It is, however, possible, to connect, with the pull-out device, a
 circumferentially closed framed formed of section tubes. In this case, the
 lower horizontal section of the frame is directly inserted in the pull-out
 rail 4 and is secured there. In this case, the lower horizontal frame
 section of the circumsferentially closed frame is constructively formed as
 the vertical web 18 of the T-shaped adaptor rail. When circumferentially
 closed frames are used, then the baskets or other containers are hanged up
 between the vertically extending legs of the lower section.
 A further embodiment of a pull-out device according to the present
 invention, together with a supported thereby pull-out frame, will be
 described below with reference to FIGS. 16-26.
 As shown in FIG. 26, a multi-part pull-out device 39 is secured to the
 bottom 27 of a tall cupboard. A vertically extending pull-out frame 40,
 which is formed of vertical front and rear bars 41 and 42 and horizontal
 upper and lower bars 43 and 44, is secured to the pull-out device 39. An
 upper guide 28 engages the upper horizontal bar 43. The upper guide 28 is
 designed for stabilizing the pull-out frame 40. The separate frame bars
 41, 32, 43, 44 can be formed as telescopic members, permitting to adapt
 the dimensions of the pull-out frame 40 to the dimensions of the tall
 cupboard 1. A plurality of baskets are hanged up between the vertical bars
 41 and 42, of which only one is shown in the drawing. A frontal screen 29
 is secured to the front vertical bar 41. The frontal screen 29 closes the
 tall cupboard 1 in the pull-in condition of the pull-out device 39. For
 connecting the front screen 29 to the pull-out frame 40, i.e., to the
 front vertical bar 41, braces 46 are provided on the front bar 41.
 A simplified pull-out device 39 used with tall cupboards is shown in FIG.
 16. In this device, the pull-out rail has a U-shaped cross section with
 two vertical webs 47 and upper bent-out flanges 48. A pair of running
 freely rotatable rollers 49 is supported in the rear region of the
 pull-out rail 4. The pull out rail 4, together with the running rollers 49
 is received in U-shaped carcass rail 2 which is secured to the bottom 27
 of the tall cupboard 1. The pull-out device 39, which is shown in FIG. 26
 has three rails, whereas the pull-out device 39 shown in FIG. 16 consists
 of two rails. The number of rails in a pull-out device is unimportant for
 the purposes of the present invention. Therefore, for the sake of clarity,
 the pull-out device 39 will be described with a reference to an embodiment
 consisting of two rails. The carcass rail 2 has, in its front region, two
 support rollers 50 which engage the side flanges 48 which serve as guiding
 tracks.
 For the purposes of the invention, the important thing is the shape of the
 pull-out rail 4 and the lower horizontal bar 44 of the pull-out frame 40.
 The pull-out rail 4 has, in its longitudinally middle region, a hook
 member 51 which opens toward the front of the rail 4 and is located
 between the two vertical webs 47. The receiving opening 52 of the hook
 member 51 is limited by two, tapering toward each other flanges, with the
 size of the opening 52 being reduced toward its bottom. The opening 52
 extend substantially horizontally.
 A shaped member 53 is provided in the front region of the pull-out rail 4,
 likewise between the two vertical webs 47. The shaped member 53 has a
 I-shaped cross-section, as shown in FIG. 19. The shaped member 53 has a
 vertical threaded bore into which a threaded bolt 54 is screwed in. At the
 lower end of the threaded bolt 54, a knurled screw 55 is arranged. The
 diameter of the knurled screw 55 corresponds approximately to the spacing
 between the two vertical webs 47. Both the shaped piece 53 and the hook
 member 51 are smaller than the width W of the pull-out rail 4. It needs
 further to be mentioned that at the rear end of the pull-out rail 4, each
 vertical web 47 has a recessed opening 56 which extends up to the flange
 48.
 The lower horizontal bar 44 of the pull-out frame 40 is formed as a
 downwardly facing U-shaped profile 57. At its rear end, the profile 57 has
 a horizontally extending bolt 58. In the longitudinally middle region of
 the profile 57, in the upper half of the profile an inner bolt 59 is
 provided. The bolt 59 is located between the two vertical webs 47. On the
 inner side of the vertical webs of the U-shaped profile 57, in their front
 regions, bolts 60 are provided. The pull-out rail 4 and the lower
 horizontal bar 44 have substantially the same length, as in conventional
 with such pull-out devices. The distance A of the bolts 60 from the
 respective upper edges of the webs of the U-shaped profile 57 is larger
 than the distance C of the opening 52 of the hook member 51 from the upper
 edge of the pull-out rail 4.
 The mounting of the frame 40 on the pull-out rail 4 is effected as follows.
 With the knurled screw 55, the shaped member 53 is displaced completely
 downward. Thereafter, the frame 40 or its lower horizontal bar 44 is
 inserted into the pull-out rail 4 and is so secured there that the bolts
 58 lie on the flanges 48 approximately between the running rollers 49 and
 the hook member 51. Then, the pull-out frame 40 is pushed, with respect to
 the pull-out rail, rearwardly. At that, the bolts 58 slide on the flanges
 48 until the bolt 49 enters the opening 52 of the hook member 51, as shown
 in FIG. 23. The bar 44 at that is in an inclined position, being inclined
 in a forward direction. Then, the shaped member 53 is lifted by rotating
 the knurled screw 55, and the bar 44 is rotated about the bolt 59 as about
 an axis until the bar 44 is located horizontally and parallel to the
 pull-out rail 4. The bolt 58, together with the rear end of the bar 44,
 are lowered and reach the rear recessed grooves 56. This fixes the frame
 40 in the pull-out rail 4 horizontally and vertically.
 The pull-out rail 4 can also have a cross-section shown in FIGS. 24-25. In
 this case, the pull-out rail 4 is formed of two symmetrically arranged
 profiles fixedly connected by a transverse web, not shown in the drawings.
 Instead of the I-shaped member 53, here, a hook member can be provided the
 shape of which is similar to the hook member provided in the
 longitudinally middle region of the pull-out rail. Instead of the hook
 member 51, here, a I-shaped member can be provided. Thus, the hook member
 51 and the I-shaped member 53 are interchangeable. The important thing is
 that one of the two members, on one hand, limits the displacement path of
 the bar 44 and, on the other had, the front end of the bar 44 can be
 lowered and lifted so that the bar 44 can be rotated about a transverse
 axis located in its longitudinal center. The advantage of using an
 I-shaped member consists in that the manufacturing tolerances need not be
 very high, i.e., the position of the bolts 59 relative to the position of
 the bolts 60 need not be precisely defined.
 In the embodiment of the pull-out device shown in FIGS. 16-26, the shaped
 member 53 is adjustable along the stationary threaded bolt 54. It is
 within the scope of the invention, to screw the bolt 54 into a nut
 provided in the transverse spar located between the two webs 47,
 connecting the same. In this case, the shaped member 53 is secured on the
 upper end of the threaded bolt 54 with a possibility of rotation relative
 to the bolt 54 but without a possibility of axial displacement relative to
 the bolt 54, i.e., the shaped member is fixed axially. Upon rotation of
 the threaded bolt, the threaded bolt is displaced axially, carrying with
 it the shaped member 53.
 The present invention was described and explained based on the construction
 of the pull-out frame 40. It is also possible to form the bar 44 as part
 of an adaptor rail. Thus, the bar 44 can be formed as a vertical web of a
 T-shaped adaptor rail which was described previously. Such an adaptor rail
 is used when instead of a pull-out frame, a section 24 is pulled out. In
 this case, the wide horizontal flange of the adaptor rail is secured to
 the bottom of a cupboard piece. Then, the cup-board piece, together with
