Description

The invention relates to a plug-shell arrangement for profiles

  closed hollows, in particular for the

  hollow section of a water level, and inserted into

  holes in the walls of the hollow profile.

  In particular, water levels are

  elongated body of rectangular section, doubly

  T or similar profile. The levels are installed appropriately in this body. The body can be

  made of wood, molded metal (preferably light metal)

  ger) or stretched profiles. He appeared particularly

  advantage of using rectangular tubes for this purpose.

  are pressed to the press as hollow sections of

  closed light metal. These rectangular tubes of-

  the advantage of a very low weight attached to a

  high rigidity. They also offer favorable conditions

  the safe and firm installation of the levels, and can be manufactured with the precision

competitive price.

  The only drawback of these rectangular tubes

  Pressed, relative to the known molded water level bodies, usually in the form of a double-T section frame, whose core is perforated in the middle, is that one can not, as with these, spend the

  hand through. This is a particular way of handling

  greatly beneficial in practice, because

  hold the water level firmly in hand, without the application of

  cation of the water level plate on the part to be aligned

be hampered.

  It is known to also provide, in the case of wooden water levels and rectangular metal tubes, such engagement openings, by milling elongate slots at appropriate places in the middle of the body. Since these slots are located near the neutral zone of the section, the water level bodies

  are not significantly weakened as a result.

  However, in the case of rectangular tubes,

  on the inside, sharp edges are formed corresponding to

  ponding. In addition, the profile is thus open inwards, so that dirt can be fixed, which is then difficult to remove. For this reason,

  in the known modes of execution, we close these openings.

  tures by taking shells, which are

  sere in the milled perforations. There are known embodiments in one piece of shells

  that kind, which are made of synthetic material

  elastically, and snap into the

  milled vertices. It is true that this fixation is

  simple, but, of course, it is not safe enough.

  In addition, in such an embodiment, it is necessary to use a relatively flexible and elastic material to manufacture the shells, so that they

  can be inserted correctly. However, a

  of this kind leads, disadvantageously, to a contraindicated deformation, and, consequently, to shells

  catch may fall out of the perforations.

  Therefore, the purpose of the invention is to provide, for closed hollow sections of this kind, suitable gripping shells, which can not only

  be easily inserted into the corresponding perforations

  but still be kept there surely.

  According to the invention, this problem is solved by two gripping shell halves inserted, by opposite sides, each in one of two perforations aligned with each other, and by the fact that the shell halves

  are connected to each other within the

  hollow yarn, by a system with grooves and tongues.

  The halves of the split plug shell can be inserted in a particularly simple manner from the outside in the respective perforations, without this requiring a particularly flexible material. The

  two halves are firmly connected to each other

  the hollow profile by perfectly closing the latter outwards, so that the shells are certainly not allowed to loosen and fall off.

  perforations. As a result, the material can be

  tively rigid. The fasteners are entirely

  covered by the closed hollow section, so that they are not visible from the outside. They close the profile completely and, after assembly, the catch shells can only be removed after having destroyed them. Preferably, the shell halves of

  overlap each other within the

  hollow in the manner of a groove and tongue assembly, so that it is ensured that the hollow profile is

  closed tightly. According to one embodiment, the agency

  characterized in that the side wall of one of the gripping shell halves forms, on the inwardly facing side of the hollow section, one or more pins which point towards the other gripping shell half, and protrude in this direction relative to the corresponding side wall, and engage in housings provided in the side wall of the other engaging shell half, on the inwardly facing side of the hollow profile and the shape of which is adapted to that of the nipples. Thus, the gripping shells inserted into the hollow profile can be further assembled

safe and not detachable.

  These assembly elements are arranged symmetrically

  on each half of the gripping shell, so that the male parts as well as the female parts of the connecting elements are arranged symmetrically distributed on one and the same half of

  catch shell. It is thus ensured that the two

  taken from the shell of the shell are of an absolute

identical.

  According to a particularly advantageous embodiment.

  tageux, the nipples are inserted in the housing.

  According to another embodiment, the nipples are fluted. In another embodiment, the nipples are ultrasonically welded in the housing. According to another

  mode of execution, the nipples are stuck in the housing.

  If the nipples and housings have a co-form

  complementarity and if the nipples are

  With respect to housing, all profiles can be firmly applied, even if they have significant width tolerances. Anchoring the shell halves of

  taken in the profile is carried out in such a way that

  formations are excluded to a large extent.

  So that the side walls relatively long

  and thin can not flex inwards, under

  effort, and jump out of the perforation, the side wall

  side of the shell shell halves, from the turned side

  towards the inside of the hollow profile, in the region of transition

  towards the peripheral edge, protrusions that engage

  in notches suitably adapted perforations.

  : According to a particularly advantageous embodiment

  tageux, the projections are integrated in the housing or the nipples. According to one variant, the projections are trapezoidal

  and diverge away from the side wall, and the

  ticks have a suitably dovetailed shape

  adapted. According to another variant, two protrusions are

  of the side wall are provided and are placed in a V

  so as to constitute the trapezoidal shape. According to a

  particularly advantageous, the notches are

  the widest edge of an appendage which projects between the projections placed in V. According to one embodiment, the hollow section is provided externally with reinforcing ribs adapted at the peripheral edges of the halves of shell of

  taken inserted. To avoid gaps between these nerves

  reinforcing vases and the peripheral edge of the catch shell halves, these can be immediately adjacent, so that the unit of the device is not

impaired.

  Other details, characteristics and advantages

  of the invention will appear in the description

  next, relating to the exemplary embodiments shown purely schematically in the drawings in which: FIG. 1 shows a water level body provided with a sectional shell arrangement along the line II of FIG. FIG. 2 shows a level of water in lateral elevation, the upper setting shell being removed on the left half, where the body is in longitudinal section and FIG. 3 shows a modified embodiment.

  these are provided, at the edge of these perforations, several

  check marks <cutouts) 4 in dovetail. In each of the

  Forages 3 is inserted, from the outside, a half of the gripping shell 5, 5 '. The setting shells are in the form of bottomless bowls. A peripheral edge in bead 6 of

  it is applied against the lateral face 7 of the recess tube

  while the side walls 8 of the gripper shell halves the perforation towards the inside of the profile. The lower edge of each of the side walls 8 is provided, on one half, with a groove 9, and on the other

  half of a tongue 10. During assembly, the tongue

  watch 10 is pushed into the groove 9, and thus closes the in-

  terstice 11, which is formed between the gripping shell halves, when the width of the profile is greater than the height of the two sidewalls together. We choose the

  height of the side walls in such a way that they

  just when the width of the profile is at the lower limit of tolerance. The width of the gap 11

  corresponds to the effective width of the profile used.

  On one of the outer side walls of the gripper shell are arranged one or more pins 12, which project relative to the side wall. On the other side wall, opposite, are arranged at the place

  corresponding overthickness 13 with holes 14.

  The studs 12 are preferably conical and have a

  some oversizing relative to holes 14.

  During assembly, the pins 12 are fitted into the holes 14, the depth of penetration can be different, in accordance with the different width of the profiles. To fasten them in this state, the nipples are of fluted shape, in known manner, or they are subjected to ultrasound by inserting them into the holes and thus welded to

  drilling, or an appropriate adhesive is applied to the holes

prayed, before fitting.

  It is also possible to perform the nipples and the holes according to a press-stud assembly,

  The sawtooth profile is directed trans-

  so that the pin 12 'can be inserted into the space 14' in such a way that the sawtooth profile 17 of the pin 12 'slides, in the manner of a snap-in, over the profile. sawtooth 16 of the rods 13 ', and that-profiles engage one into the other, in accordance with the not sawtooth, so that it is impossible to remove the pin 12'. Thus, it is impossible to detach after the event the gripping shells 5, 5 'assembled, unless destroying the shells themselves. For adaptation to different thicknesses of the water level body profile, the pin 12 'can be introduced and anchored at a different distance in the spacing 14' between the legs.

to a joined application.

  The saw teeth of the profiles 16 and 17 have dimensions substantially harmonized with each other, so that the teeth of the profile -17 of the stud 12 'can engage in the transverse grooves formed between the teeth of the profile 16 of the rods 13'. The end of the saw teeth of the profile 17 of the stud 12 'is blunted, in a measure which increases toward the free end of the stud 12'. This makes it possible to introduce the stud 12 'with less friction in the spacing 14', the oblique surfaces of the leading teeth 18 of the stud 12 'spacing the corresponding oblique surfaces of the leading teeth 19 from each other. chopsticks 13 '. The blunt form of the teeth allows, in addition, the saw teeth of the profile 17 to apply more closely in the recesses between the saw teeth of the rods 13 '. This kind of assembly elements is also provided, on the shell halves, in the same way as the elements

  thus firmly grip the sidewalls 8 of the grip shell halves to the side faces 7 of the body of the

water level.

  Such gripper fastenings may be provided not only for water level bodies, but for all articles made of hollow sections with parallel sidewalls, for example gauges, adjustment battens, talking patterns, etc.
