Description:
BACKGROUND OF THE INVENTION 
     The invention concerns a railing for a movable furniture part, comprising a railing strut and a panel fixing device at one end of the railing strut for fixing the railing to a front panel of the movable furniture part, wherein a mounting portion of the panel fixing device can be fixedly connected to the front panel. 
     The invention further concerns a movable furniture part with at least one railing of the kind to be described. The invention also concerns an article of furniture comprising a railing of the specified kind. 
     There are already a large number of railings of the kind noted above, belonging to the state of the art. For example, DE 295 07 834 U1 of Aug. 24, 1995, discloses a railing which at one end of the railing bar has a fixing fitment screwed into the railing bar. That fixing fitment has a conically narrowing fixing head having radially projecting projections which are sharpened in the manner of a cutting edge. Then, mounting of the railing bar to the front panel is effected in such a way that the fixing head which is pre-mounted to the railing bar but which has not yet been entirely screwed as far as the end surface is introduced into the fixing base, more specifically in an inclined position such that the lower inclined surface line of the fixing head bears against the wall of the fixing bore in the front panel. In that position, the fixing head can be pushed completely into the fixing bore as the radially upwardly projecting projection which is sharpened in a knife edge-like configuration is moved downwardly to such an extent that it does not engage the oppositely disposed wall region of the fixing bore. As soon as the fixing head is pushed completely into the fixing bore, the railing bar is then pivoted into the horizontal position, in which case the free end of the fixing head is raised and the sharpened projection penetrates into the wall of the fixing bore and thus provides a positively locking fixing action in the fixing bore. By rotating the railing bar in the screwing-on direction on to the threaded shank of the fixing head the end of the railing bar is screwed on until it bears against the inside flat side of the front panel and a gap which possibly still exists there is caused to disappear (from the preamble to the description of DE 295 07 834 U1). 
     A further railing is disclosed in AT 506 783 A4 of Dec. 15, 2009. That railing has an incorporated inclination adjustment for the front panel of a drawer. In that arrangement, the railing has a displaceable cover cap to cover over the adjustment and fixing mechanism of the railing strut. 
     SUMMARY OF THE INVENTION 
     The object of the invention is to provide an improved railing. 
     According to the invention that object is attained in that the railing strut is at least partially hollow and is adapted to be displaceable relative to the mounting portion. The railing strut which is displaced in the direction of the mounting portion receives and covers the panel fixing device. In that way, it is possible to achieve an esthetically attractive railing as in that way only the railing strut in itself is visible and all other mounting portions—like for example the panel fixing device—are no longer visible after mounting of the railing has been effected. 
     It has proven to be particularly advantageous if the mounting portion of the panel fixing device can be fixedly connected to the front panel by a spreading connection. A firm hold for the railing in the front panel can be achieved by a spreading connection. 
     In a preferred embodiment, the spreading connection can be activated by a movement of the railing strut relative to the mounting portion of the panel fixing device. That can provide that no tool is needed to produce the spreading connection between the railing strut and the front panel. 
     It can further preferably be provided that the panel fixing device has at least one joint, wherein spreading of the spreading connection can be actuated by pivotal movement of a pivot lever of the joint. That makes it possible to achieve a particularly simple and fast method of fixing the railing to the front panel. 
     It has been found to be particularly advantageous if the railing has a sleeve for partially receiving the panel fixing device, wherein the sleeve is provided substantially completely in the interior of the railing strut. The use of a sleeve makes it possible to achieve stable contact between the panel fixing device and the railing strut. 
     It is particularly preferable that the sleeve has an abutment surface for abutment of the sleeve against the front panel. In that way, it is possible to prevent damage to the front panel when fitting the railing. 
     In that respect, it is proven to be particularly advantageous if the sleeve and the panel fixing device have mutually corresponding latching portions for fixing the sleeve to the panel fixing device. The use of latching portions affords a particularly fast and simple way of mounting the sleeve to the panel fixing device. 
     In a preferred embodiment, the railing strut and the sleeve have mutually corresponding latching portions for fixing the railing strut to the sleeve. In that way the railing strut can be easily fixed to the sleeve. 
     It has further proven to be advantageous if the mutually corresponding latching portions of the railing strut and the sleeve can be coupled together and uncoupled from each other. Thus, the railing strut can be released from the sleeve again. That, therefore, permits easy replacement of possibly damaged parts of the railing in a simple procedure. 
     It has proven to be advantageous if the railing strut is in one piece. The use of a one-piece railing strut makes it possible to avoid long mounting times for the railing strut itself. 
     Further, the railing preferably has a rear wall fixing device at the other end of the railing strut for fixing the railing to a rear wall of the movable furniture part. The rear wall fixing device is provided substantially completely at the side of the railing (that is, towards the internal space of the movable furniture part), and corresponds to an end face portion of the rear wall. 
     In specific terms, a movable furniture part can have at least one railing. Advantageously, the movable furniture part has two railings. 
     In addition, an article of furniture comprising a furniture carcass and at least one movable furniture part. Preferably, in that case, the movable furniture part is in the form of a drawer.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  shows an exploded perspective view of a railing  1  for a movable furniture part  102  (not shown) (see  FIGS. 3 through 5 ). 
     The railing  1  has a railing strut  2  and a panel fixing device  3  at a first end  21  of the railing strut  2  for fixing the railing  1  to a front panel  103  (not shown) of the movable furniture part  102 . For that purpose, the panel fixing device  3  has a mounting portion  31  which can be connected to the front panel  103 . In this arrangement, provided on the mounting portion  31  is a joint spindle  35  ( FIG. 2 ) which corresponds to a through opening  36  in the joint lever  34 . The mounting portion  31  and the joint lever  34  in that case form the joint  33 . The mounting portion  31  is spread or released by a pivotal movement of the joint lever  34  relative to the mounting portion  31 , whereby a connection with the front panel  103  can be made or released respectively. Such spreading connections are already known from the state of the art and are no longer novel (see in that respect for example EP 0 698 357 A1 of Aug. 21, 1995). 
     In the assembled condition, the joint lever  34  of the panel fixing device is inserted in the guide portion  5 . The guide portion  5 , in turn, has a latching portion  52  corresponding to a (first) latching portion  42  of the sleeve  4 . The sleeve  4  in turn also has a further (second) latching portion  43  corresponding to a latching portion  23  of the railing strut  2 —in this case in the form of a through opening. 
     In this preferred embodiment, the railing strut  2  has a substantially completely hollow interior  22  and can thus accommodate in its interior the sleeve  4 , the guide portion  5  and the joint lever  34  and also in part the mounting portion  31  (see in this respect  FIG. 5 ). 
     At one end, the sleeve  4  has an abutment surface  41  provided for abutment against the front panel  103  to prevent damage to the railing strut  2  or the front panel  103  in the assembly procedure. 
     In this case, the corresponding latching portions  43  and  23  of the railing strut  2  and the sleeve  4  are adapted to be coupled together and uncoupled from each other. Thus the railing strut  2  can also be subsequently removed again from the sleeve  4  or the panel fixing device  3  accommodated in the sleeve  4 . 
       FIG. 3  shows a perspective view of a drawer  102  which has, inter alia, a front panel  103  and a rear wall  104 . The mounting portion  31  of the railing  1  is already inserted in the front panel  103 , but not yet fixed. Fixing is effected by way of a spreading connection  32  whereby the mounting portion  31  of the panel fixing device  3  can be fixedly connected to the front panel  103 . Spreading of the spreading connection  32  is effected by rotating the panel fixing device  3  relative to the front panel  103 . The panel fixing device  3  is already partially adapted to be pre-fitted in the railing strut  2 . As a result, the spreading connection  32  can be activated by a movement of the railing strut  2  relative to the mounting portion  31  of the panel fixing device  3 .  FIG. 3  shows only one railing  1 , but in practice it is provided that a drawer  102  has two such railings  1 . 
     It will be appreciated that the railing  1  could also be fixed to a front panel  103  in a different way, like for example by screwing in, pressing in, insertion or for example by means of an expander dowel or the like. 
       FIG. 4  shows the drawer  102  with the railing  1  already partially fitted. In this view, the spreading connection  32  is already activated as the joint lever  34  of the panel fixing device  3  spreads open the mounting portion  31  by way of the joint spindle  35  of the mounting portion  31 , and has thus fixedly anchored the mounting portion  31  in the front panel  103 . At that time, the panel fixing device  3  is still partially visible, the procedure for mounting the railing  1  is not yet concluded. 
     As is clearly visible from  FIG. 4  in this case, the railing strut  2  of the railing  1  is in one piece. It will be appreciated that equally it could comprise a plurality of parts. 
     Spreading of the spreading connection  32  was achieved by pivotal movement of the pivot lever  34  of the joint  33  of the panel fixing device  3 . It will be appreciated that it is also possible to envisage that a spreading connection  32  can also be implemented in a different way, like for example by rotation of the railing strut  2  about its longitudinal axis, as is also already known from the state of the art. 
       FIG. 5  shows a perspective view of a drawer  102 , in which the railing  1  is completely fitted in place. Because the railing strut  2  is at least partially hollow and is adapted to be displaceable relative to the mounting portion  31  (not shown), the railing strut  2  can be displaced in the direction of the mounting portion  31  and in that case completely covers the panel fixing device  3 . Thus, as shown in  FIG. 5 , the railing strut  2  together with the front panel  103  completely enclose the panel fixing device  3  (panel fixing device  3  is not visible). This, therefore, provides an esthetically attractive railing  1 , in which there is no need for an additional cover for the panel fixing device  3  as the railing strut  2  accommodates the panel fixing device  3  in itself. 
     Disposed at the second end  24  of the railing  1 , that is towards the rear wall  104 , is a rear wall fixing device  6  as shown in  FIG. 6   a . In this case, the rear wall fixing device  6  is provided substantially completely at the side of the railing  1 , that is towards the internal space of the movable furniture part  102 , and in that case corresponds to an end face portion  105  of the rear wall  104  (see  FIGS. 7   a  and  7   b ). After the railing strut  2  has been pushed over the panel fixing device  3  the railing strut  2  can be clipped on to the end face portion  105  of the rear wall  104  by the rear wall fixing device  6 . It is possible in that way to achieve rapid mounting of the railing  1 . 
       FIG. 8  shows an article of furniture  100  comprising a furniture carcass  101  and movable furniture parts  102  which are arranged therein and which are in the form of drawers. The drawers  102  each have two railings  1 .
