  Throughout the description, the same reference numerals are used to denote identical elements.

  FIG. 1 is a perspective view of a prior art means for fixing a drive mechanism of a wiper device to the inner surface of a body shell.

  That is, FIG. 1 shows a drive mechanism 1 of a known type of windscreen wiper device 2, which is in the form of a support plate 3 having a drive shaft 4, and the drive shaft 4 is a wiper device. Through the opening 5 provided in the rear door 6 to which the drive mechanism 1 is fixed.

  The rear door 6 of the automobile includes a body shell 7 formed from a cut and bent seat, and a window 2.

  The body shell 7 is provided on its inner surface 7a corresponding to the inner surface of the rear door 6 with a drive mechanism 1 for a device for wiping the outer surface of the window 2, such as a well-known type of windscreen-wiper blade.

  In the prior art shown in FIG. 1, the support plate 3 includes two radial arms 8, and the free end 9 of the radial arm 8 is inserted into the opening 11 of the support plate 12 fixed to the inner surface 7 a of the body shell 7. And the radial finger 10 which can be firmly attached is provided.

  FIG. 1 shows only the support plate 3 having two radial arms 8, but three radials are provided so that the drive mechanism 1 can be more favorably fixed to the inner surface 7 a of the body shell 7 of the rear door 6. The support plate 3 having the arms 8 may be formed.

  FIG. 2 is a partial perspective view of the first embodiment of the fixing means 13 for fixing the drive mechanism 1 to the inner surface 7 a of the body shell 7.

  The drive mechanism 1 shown in FIG. 2 includes three radial arms 8. That is, one is the left radial arm 8a, one is the central radial arm 8b, and one is the right radial arm 8c.

  Fixing means 14 and 15 for fixing the radial arms 8a, 8b and 8c to the inner surface 7a of the body shell 7 are provided at the free ends 9 of the three radial arms 8a, 8b and 8c, respectively.

  FIG. 2 shows two embodiments of means for fixing the radial arms (8a, 8b, 8c) constituting the means for fixing the drive mechanism 1 to the body shell 7. FIG. 3 and 4 show the first embodiment 14, and FIG. 5 shows the second embodiment 15.

  Only based on the fixing means 14 of the first embodiment for fixing the radial arm, only based on the fixing means 15 of the second embodiment for fixing the radial arm, or of the fixing means of the radial arm Based on the combination (14, 15) of the two embodiments, the fixing means 13 of the drive mechanism 1 can be manufactured.

  The left and right radial arms (8a, 8c) are fixed to the body shell 7 by the fixing means 14 of the first embodiment for fixing the radial arms. This fixing means 14 forms a substantially plug-type cylinder 16 and is shown in more detail in FIGS.

The plug-type cylinder 16 has three parts:
-A substantially disc-shaped upper end portion called "upper end disc"17;
-A disc-shaped intermediate part called "intermediate disk" 18 having a larger diameter than the disk of the upper end part 17;
A lower end portion of a truncated pyramid shape having a circular base, in which the diameter of the circular base is smaller than the diameter of the intermediate disk 18 but larger than the diameter of the upper end disk 17, and the circular base is the lower end surface 18 a of the intermediate disk 18. And a lower end disk 19 facing the head.

  The upper disk 17 and the intermediate disk 18 are spaced apart so that a circular gap called an upper gap 20 is formed between them.

  Similarly, the intermediate disk 18 and the base of the lower truncated pyramid are spaced apart to form a gap called a lower end gap 21.

  Therefore, due to the cylindrical shape of the plug-type cylindrical body 16, the upper and lower gaps (20, 21) have a diameter smaller than the diameter of the circular base of the upper end disk 17, the intermediate disk 18, and the truncated pyramid lower end disk 19. An intermediate cylinder portion of the mold cylinder 16 is formed.

  The free end 9 of each radial arm (8a, 8b, 8c) is in the form of two curved teeth 22 forming a circular inner space 23, and an upper end gap 20 is formed in the circular inner space 23 by its complementary shape. Can be inserted.

  Thus, when the drive mechanism 1 is fixed, the plug-type cylindrical body 16 is attached to the radial arm (8a, 8b, 8c) so that the pyramidal lower end disk 19 is directed to the inner surface 7a of the body shell 7. On the other hand, it can be firmly attached.

  Further, an inner opening 16a having a function to be described later is provided at the center of the upper end surface 17a of the upper end disk 17 of the plug-type cylindrical body 16.

  The plug-type cylinder 16 is advantageously formed from a slightly deformable semi-rigid material, such as rubber.

  FIG. 5 shows a side view of the fixing means 15 of the second embodiment for fixing the radial arm shown in FIG. 2, more precisely, means for fixing the central radial arm 8 b to the body shell 7. It is.

  The second fixing means 15 for fixing the radial arm 8 includes a plug-type columnar body 16 by the fixing unit 14 in the first embodiment for fixing the radial arm 8. The cylindrical second plug-type cylindrical body 24 is fixed by the radial tongue 25, and the radial tongue 25 is firmly attached to the second plug-type cylindrical body 24 so that the radial tongue 25 is free. The end 26 is fixed to the upper end surface 17 a of the upper end disk 17 of the first plug-type cylindrical body 16.

  Thus, the tongue 25 forms a material bridge between the two cylinders 16, 24.

  In addition, a truncated pyramid 27 having a circular base whose diameter is slightly smaller than the diameter of the second plug-type cylindrical body 24 is provided at the lower end of the second plug-type cylindrical body 24.

  A circular gap 28 between the circular base of the truncated pyramid 27 and the remaining portion of the second plug-type cylindrical body 24 is formed between the main cylindrical body 24a and the truncated pyramid 27 having a circular base.

  The circular base of the truncated pyramid 27 of the second plug-type cylindrical body 24 faces the lower end 24b of the main cylindrical body 24a.

  6 shows the body shell so that it can cooperate with the fixing means 15 of the second embodiment for fixing the radial arm shown in FIG. 5 and the fixing means 14 of the first embodiment. 7 is a partial front view of an opening provided in FIG.

  Actually, a part of the fixing means 15 of the second embodiment for fixing the radial arm is formed based on the fixing means 14 of the first embodiment for fixing the radial arm. 6 also shows an opening 29 which can cooperate with the fixing means 14 of the first embodiment for fixing the radial arm.

Accordingly, FIG. 6 shows two openings 29, 30. That is,
The first opening 29, called the main opening, can cooperate with the fixing means 15 of the first embodiment for fixing the radial arm, ie the first plug-type cylinder 16;
The second opening 30 can cooperate with a second plug (cylindrical body) 24 included in the fixing means 15 of the second embodiment for fixing the radial arm.

  The first opening 29 has an approximately eight-letter shape, and one loop called the main loop 29a has a larger diameter than the other loop called the sub-loop 29b.

  The diameter of the main loop 29 a is larger than the diameter of the circular base of the truncated pyramid 19 of the first plug (cylindrical body) 16, but smaller than the diameter of the intermediate disk 18 of the first plug 16.

  The diameter of the secondary loop 29 b is smaller than the diameter of the main loop 29 a, but smaller than the diameter of the circular base of the truncated pyramid 19 and the diameter of the intermediate disk 18.

  The diameter of the secondary loop 29b is advantageously slightly smaller than the diameter of the cylindrical part forming the lower end gap 21.

  When the plug-type cylindrical body 16 is fixed to the inner surface 7a of the body shell 7, the user inserts the lower end disk 19 of the plug-type cylindrical body 16 into the first opening 29 at the same height as the main loop 29a. .

  Due to the difference in diameter, the user can only insert the lower end disk 19 of the plug-type cylinder 16 through the main loop 29a of the first opening 29, after which the lower end face 18a of the intermediate disk 18 The body shell 7 comes into contact with the inner surface 7a and stops.

  In order to block the plug cylinder 16 in a fixed position, the user is directed towards the sub-loop 29b of the opening 29 having a diameter slightly smaller than the diameter defined by the circular lower end gap 21. Translate.

  Since the first cylindrical body 16 is formed of a semi-rigid material that can be slightly deformed, a compressive force is generated between the lower end gap 21 and the periphery of the sub-loop 29b. The first opening 29 is held in a predetermined position within the sub-loop 29b.

  The diameter of the second opening 30 is slightly smaller than the diameter of the circular base of the truncated pyramid 27 of the second plug-type cylindrical body 24 and the diameter of the main cylindrical body 24 a of the second plug-type cylindrical body 24.

  However, the second plug 24 is also formed of a semi-rigid material that is slightly deformable, and there is a difference in diameter between the circular base of the truncated pyramid 27 and the second opening 30, and therefore the second plug 24. The second truncated pyramid 27 can be inserted into the opening 30 and the second cylindrical body 24 can be blocked and locked in the second opening 30.

  Accordingly, when there are three radial arms (8a, 8b, 8c) for fixing the drive mechanism 1 to the inner surface 7a of the body shell 7, the three main openings 29 are formed on the inner surface 7a, That is, it is provided on the seat of the rear door 6.

  The free end 9 of the right and left radial arms 8a, 8c is provided with the plug-type columnar body 16 shown in FIGS. 3 and 4 which is the fixing means 14 of the first embodiment for fixing the radial arms. The plug-type cylindrical body (16, 24) shown in FIG. 5 which is the fixing means 15 of the second embodiment for fixing the radial arm is provided at the free end of the central radial arm 8b.

  When the drive mechanism 1 is fixed to the body shell 7, the user must insert the pyramidal lower end 19 of the cylindrical body 16 into the main loop 29 a of the first opening 29 in the first step.

  As a result, the lower end surfaces 18 a of the three intermediate disks 18 of the three cylindrical bodies 16 come into contact with the inner surface 7 a of the body shell 7 and stop.

  Thereafter, the user performs a rotation operation (clockwise rotation shown in FIG. 2) and slides the lower end surface 18 a of the intermediate disk 18 on the inner surface 7 a of the body shell 7, thereby lowering the lower end of the plug-type cylinder 16. The gap 21 is inserted into the sub-loop 29b and is deformed by the lower end gap 21 to form a compression force, thereby blocking the plug-type columnar body 16 with respect to the body shell 7 in the sub-loop 29b of the opening 29.

  The plug-type cylindrical body 16 of the lower arm 8b is placed in the sub-loop 29b of the main opening 29 so that the plug 16 does not come off the main opening 29 due to inadvertent rotation in the counterclockwise direction. The plug-type cylindrical body 24 having the pyramid-shaped end pyramid base 27 that can be inserted into the sub-opening 30 by deformation after being blocked by is provided.

  In this way, means for locking and blocking the fixing means 14, 15 are formed.

  In order to unlock the fixing means 14, 15 of the radial arms 8 a, 8 b, 8 c, a longitudinal tensile force is applied to the tongue 25, and the second cylindrical body 24 blocked in the sub-opening 30 is It is desirable to pull the gap 28 apart and then slide the main plug-type cylindrical body 16 from the secondary loop 29b to the main loop 29a by a rotating operation.

  A person skilled in the art determines the positions of the first and second openings 29, 30 according to the length of the radial arms 8a, 8b, 8c, the length of the tongue 25, and the number of the radial arms 8a, 8b, 8c. It goes without saying that it can be done.

  Similarly, those skilled in the art will adjust the diameter of the openings to the diameter of the cylinders 16, 24, particularly the intermediate disk, so that the cylinders 16, 24 can be blocked within the openings 29, 30 by the formation of deformation and compression forces. 18, the diameter of the cylindrical part forming the lower end gap 21, and the diameter of the circular base of the truncated pyramids 19 and 27 can be adapted.

  FIG. 7 is a perspective view of an alternative embodiment of the sub-opening 30 that can cooperate with the fixing means 15 of the second embodiment for fixing the radial arm.

  According to this alternative embodiment, the secondary opening 30 capable of cooperating with the secondary plug type cylinder 24 has an 8-shaped shape having a primary loop 30a and a secondary loop 30b having a smaller diameter than the primary loop 30a. I am doing.

  FIG. 8 shows another embodiment of the secondary opening 30 in a precise manner.

  The other elements shown in the previous figure remain the same.

  According to this new embodiment, the tongue 25 of the sub-plug cylinder 24 is centered on the longitudinal axis of the main plug cylinder 16 on the upper end surface 17 a of the upper disk 17 of the main plug cylinder 16. It is fixed so that it can rotate.

  In this way, the secondary plug type cylinder 24 can be rotated about the longitudinal axis of the main plug type cylinder 16.

  Therefore, after inserting the cylindrical body 16 into the main loop 29a of the main opening 29, the user inserts the pyramidal end portion of the sub-plug-type cylindrical body 24 into the sub-opening 30 like the sub-opening 30 shown in FIG. When inserting the pyramid base 27, the pyramid base 27 at the pyramidal end of the sub plug-type cylindrical body 24 is inserted into the main loop 30a of the sub opening 30 without requiring excessive deformation force. be able to.

  In order to allow the fixing means 14, 15 to be blocked, the user then rotates the sub-plug cylinder 24 from its position in the main loop 30a to its position in the sub-loop 30b. In the sub-loop 30b, the sub-plug type cylindrical body 24 is held at a predetermined position by deformation and generation of a compressive force in the circular gap 28 of the second plug 24. This is because the diameter of the circular gap 28 is slightly larger than the diameter of the secondary loop 30 b of the secondary opening 30.

  A person skilled in the art determines the positions of the first and second openings 29, 30 according to the length of the radial arms 8a, 8b, 8c, the length of the tongue 25, and the number of the radial arms 8a, 8b, 8c. Needless to say, it can be determined.

  Similarly, those skilled in the art will determine the diameter of the openings, such as the diameter of the cylinders 16, 24, in particular the diameter of the intermediate disk 18, so that the plugs 16, 24 can be blocked within the openings 29, 30 by deformation and compression forces. It can be adapted to the diameter of the cylindrical part forming the lower end gap 21 and the diameter of the circular base of the truncated pyramids 19, 27.

  FIG. 9 is a partial view of an opening provided in the body shell so as to be able to cooperate with the means of the third embodiment according to the invention for fixing the radial arm.

  In this embodiment, a main opening 29 having a main loop 29a and a sub-loop 29b is provided, and these loops 29a and 29b can cooperate with the cylindrical body 16 as described above.

  A rectangular sub-opening 31 is also provided.

  The main opening and the sub-openings 29, 31 can cooperate with the fixing means 32 of the third embodiment shown in FIGS. 10 and 11 as a side view and a 3/4 plan view, respectively.

  The fixing means 32 according to the third embodiment is the same as the fixing means of the second embodiment shown in FIG. 5 except that the second plug-type cylindrical body 24 is replaced with a substantially parallelepiped element 33. 15 and substantially parallel hexahedron element 33 with a pair of folding tabs 34 at its free end, the folding tabs 34 being oriented generally towards the tongue 25 and substantially parallelepipedal. Arranged on the two side surfaces on both sides of the element 33, more precisely on the two full widths of the rectangular cross section of the substantially parallelepiped element 33.

  Accordingly, the substantially parallelepiped element 33 has a substantially arrow shape with a flat tip when viewed from the front.

  Advantageously, the folding tab 34 is tilted with respect to a vertical axis which is the longitudinal axis of the main plug 16. More precisely, it is preferable to be inclined by an angle of 1 to 30 °, more precisely an angle of 1 to 10 °.

  Also, the folding tab 34 is formed from the same type of deformable material used, for example, for the main cylinder 16.

  When the plug-type cylindrical body 16 is fixed to the inner surface 7a of the body shell 7, the user inserts the lower end portion 19 of the plug-type cylindrical body 16 into the main opening 29 at the same height as the main loop 29a, and circularly. The plug-type cylindrical body 16 is translated toward the sub-loop 29b of the main opening 29 having a diameter slightly smaller than the diameter defined by the lower end gap 21 of the first plug-type cylinder, as described above. Block body 16.

  The plug-type cylindrical body 16 of the radial arm 8b includes a substantially parallelepiped element 33 so that the cylindrical body 16 does not disengage from the main opening 29 due to unintentional rotation in the counterclockwise direction. The free end 33 can be inserted into the rectangular sub-opening 31 after the plug-type cylinder 16 is blocked in the sub-loop 29 b of the main opening 29.

  At this time, the free end of the bending tab 34 abuts on the outer surface 7b of the body shell 7 and exerts a holding force on the outer surface 7b.

  This insertion of the substantially parallelepiped element 33 is possible because the folding tab 34 is made of a slightly deformable material, and thus the drive mechanism 1 can be locked to the body shell 7.

  Due to the shape of the folding tab 34 that is tilted and oriented vertically, once the folding tab 34 is inserted into the rectangular sub-opening 31 as shown in FIG. In addition to the bending tabs 34, unless these tabs are pressed against the substantially parallelepiped element 33 and then a longitudinal force is applied to remove the free end of the generally parallelepiped element 33 away from the opening 11, The substantially parallelepiped element 33 cannot be removed from the rectangular sub-opening 31.

  That is, the substantially parallelepiped element 33 cannot be removed by applying a tensile force to the tongue 25 as in the fixing means 15 of the second embodiment.

  A person skilled in the art can determine the positions of the openings 29 and 30 according to the length of the radial arms 8a, 8b and 8c, the length of the tongue 25, and the number of the radial arms 8a, 8b and 8c. Needless to say.

  Similarly, those skilled in the art can adapt the dimensions of the openings 29 and 31 according to the dimensions of the cylindrical body 16 that is the main plug and the dimensions of the substantially parallelepiped element 33.

  FIG. 13 can cooperate with the fixing means 35 of the fourth embodiment for fixing a radial arm according to the invention, shown in FIGS. 14 and 15 respectively as a side view and a plan view. FIG. 6 is a partial front view of an opening provided in the body shell 7.

  More specifically, the body shell 7 has an acute angle with respect to a plane defined by a pair of openings, ie, the main opening 29 having two loops 29a and 29b and the surface of the body shell 7, for example as described above. And a sub-opening 36 having projecting teeth 37 that are preferably inclined.

  The sub-opening 36 is advantageously square, and the protruding teeth 37 are provided on one of the square sides. More precisely, it is provided on the side of the square facing the secondary loop 29b of the main opening 29, so that the protruding teeth 37 are directed towards the opposite side of the square, so that the square secondary opening The inner space defined by 36 is substantially supplemented by protruding teeth 37.

  It goes without saying that the sub-openings 36 may be rectangular or triangular, or any other suitable shape.

  The fixing means 35 of the third embodiment according to the present invention has a substantially planar extension at the same height as the intermediate disk 18, that is, a rectangle having an opening 39 on the inside at the same height as its end. The first plug-type cylinder 16 having the tongue portion 38 as described above is formed.

  FIG. 16 shows the fixing means 35 of the fourth embodiment fixed to the body shell 7.

  In order to allow the fixing means 35 to be blocked and locked, the user must first insert the plug-type cylinder 16 into the main opening 29 provided in the body shell 7 as described above.

  The user advances the cylindrical body 16 into the sub loop 29b of the main opening 29, and blocks and locks the drive mechanism 1 at this position, and the fixing means (14, 35) is moved by unintentional movement. If it does not come off, the protruding tooth 37 can be inserted into the opening 39 of the tongue 38. In this case, the inclination of the protruding teeth 37 is such that the protruding teeth 37 exert a pressing force that opposes the pressing operation from the secondary loop 29b toward the main loop 29a.

  A person skilled in the art can determine the dimension of the tongue 38 according to the positions of the sub-openings 36 and the protruding teeth 37, and it goes without saying that the shape of the protruding teeth 37 is any suitable shape.

  It is beneficial to make the free end of the tongue 38 thicker than the other parts of the tongue 38, so that the inclination and height of the protruding teeth 37 can be determined to be large and small. The protruding teeth can remain confined within the inner space defined by the openings 39 of the.

  Alternatively, a part of the side surface of the protruding tooth 37 can be directly attached to the outer surface 7 b of the body shell 7. For example, the two side surfaces of the protruding teeth can be directly attached to the outer surface 7 b of the body shell 7. In this way, the rigidity of the protruding teeth 37 is enhanced.

  FIG. 17 is a partial perspective view of an embodiment with an opening 29 provided in the body shell 7 so as to be able to cooperate with the fixing means 14 of the first embodiment for fixing a radial arm as described above. FIG.

  More precisely, in this alternative embodiment of the main opening 29, a blocking means 40 for blocking the main plug 16 is provided in the secondary loop 29b of the main opening 29.

  The block means 40 has a pair of teeth provided around the main opening 29a at the same height as the center of the main opening 29, that is, at the same height as the intermediate portion between the main loop 29a and the sub-loop 29b. 41 forms.

  The teeth 41 are tilted slightly with respect to the plane defined by the surface of the body shell 7, preferably at an angle of less than 45 °.

  For example, the tooth 41 shown more precisely in FIG. 18 forms a slot in the surface of the body shell 7 sheet, and is bent by lifting a portion of the sheet thus divided so as to be sharp. A generally triangular inclined tooth 41 having an edge 42 is formed.

  In this way, the tooth 41 has a raised pointed end with a retaining edge formed by a sharp edge 42, the end of which the plug-type cylinder enters into the secondary loop 29 b of the main opening 29. When advanced, the plug-type cylinder 16 can be locked.

  Each tooth 41 has a side surface 41a that is the same as the surface of the body shell 7, a second side surface 41b that defines the periphery of the main loop 29a, and a raised third side surface 41c formed by a slot formed in the body shell 7. The connecting portion between the second side surface 41 b and the third side surface 41 c forms a pointed end portion of the tooth 41.

  It is advantageous if the plug-type cylinder 16, more precisely the intermediate disk 18, can be slid over the teeth 41 so as to be blocked in the secondary loop 29b.

  In practice, the plug-type cylinder 16 can be slightly deformed at the same height as the intermediate disk 18 and can pass from the main loop 29a to the sub-loop 29b.

  When the plug cylinder 16 is in this position, the edges 42 of the teeth 41 prevent the opposite movement from occurring due to the protuberance, and the user places the teeth at the same height as the surface of the body shell 7. Thus, a longitudinal force must be applied to the teeth 41 to allow the plug-type cylinder 16 to pass from the secondary loop 29b to the main loop 29a.

  It is advantageous if the teeth 41 are provided in each of the main openings 29 of the means for fixing the radial arms 8a, 8b, 8c, but these blocking means are only in one or two main openings 29. It should be understood that 40 can be provided.

  FIG. 19 shows a second specific view of the blocking means 43 provided in the main opening 29 of the body shell 7 so as to be able to cooperate with the fixing means 14 of the first embodiment for fixing the radial arm. FIG. 20 is a partial perspective view of the embodiment, and FIG. 20 is an enlarged view of the second embodiment of the block means 43.

  According to this alternative embodiment, the blocking means 43 for blocking the plug-type cylinder 16 in the secondary loop 29b is substantially biplanar and is at the same height as the center of the main opening 29, i.e. It consists of a pair of raised portions or stoppers 44 arranged around the main loop 29a at the same height as the intermediate portion between the main loop 29a and the sub-loop 29b.

The stopper 44 is
A first triangular plane 45 having one side 45a in the same plane as the surface of the body shell 7, a second side 45b defining the periphery of the main loop 29a, and a third side 45c;
-One side 46a in the same plane as the surface of the body shell 7, a second side 46b defining the periphery of the main loop 29a, and a third side that is the same as the third side 45c of the first triangular plane 45 And a second triangular plane 46 having a side 46c.

  The first and second triangular planes 45, 46 are considerably raised with respect to the surface of the body shell 7.

  Advantageously, the first triangular plane 45 has an inclination that is less than the inclination of the second triangular plane 46.

  Due to its structure, the second triangular plane 46 is formed by a connecting portion of the second and third sides 45b, 45c and has a tip that is oriented substantially towards the main loop 29a.

  The inclination of the second triangular plane 46 is such that when the main plug-type cylindrical body 16 is introduced into the secondary loop 29b by sliding, this plug is blocked at a predetermined position in the secondary loop 29b. ing. As a result, the second triangular plane 46 stops the cylindrical body 16 in the secondary loop 29b unless an appropriate pressing force is applied to remove the cylindrical body 16 from the secondary loop 29b by deformation. Forming means for blocking.

  Those skilled in the art will be able to define the number, size, shape and inclination of the planes that form the stopper 44, which is a bulge, in order to achieve blocking and locking of the cylinder 16 within the secondary loop 29b.

  FIG. 21 is a perspective view of the fixing means 41 of the fifth embodiment for fixing the radial arm of the drive mechanism 1.

  FIG. 21 shows the fixing means 47 according to the fifth embodiment provided at the same height as the fixing means of the central radial arm 8b, and the other radial arms 8a and 8c use the fixing means 14 described above. That is, it is fixed to the body shell 7 using only the plug-type cylindrical body 16.

  According to this embodiment, the fixing means 47 is formed from, for example, a plug-type cylindrical body 48 shown in three perspective views in FIGS. 22 to 24, and this cylindrical body 48 is, for example, the body shown in FIG. It can cooperate with an opening 49 provided in the shell.

The plug-type cylinder 48 is
An upper end portion of a circular portion 50 having a rectangular portion 51 adjacent to the periphery thereof, the upper end portion being provided with an opening 52, more precisely, an opening 52 extending over the circular portion 50 and the rectangular portion 51. Thus, the opening 52 also has an upper end portion having a circular shape 53 with a rectangular portion 54 adjacent to the periphery of the circular portion 53, and
A disc-shaped intermediate part 55;
A lower end portion 56 having a substantially truncated pyramid shape having a circular base, the diameter of the circular base being smaller than the diameter of the intermediate portion 55, and the circular base disposed opposite the lower end surface 55 a of the intermediate disc 55. It consists of a lower end portion 56.

  Advantageously, the circular portion 53 of the opening 52 in the upper end portion is provided through the lower end portion 56 and the intermediate portion 55 of the plug-type cylinder 48.

  On the other hand, the rectangular portion 54 of the opening 52 passes through the intermediate portion 55, but only partially passes through the lower end portion 56, whereby the parallel hexahedral internal cavity 57 is formed in the lower end portion 56. Is formed.

  The upper end portion and the intermediate portion 55 are spaced apart so as to form a circular upper end gap 58 therebetween.

  Similarly, a lower end gap 59 is formed by separating the intermediate portion 55 and the base of the lower end portion 56 which is the lower end truncated pyramid.

  As can already be seen, the free end 9 of the central radial arm 8 b is in the form of two curved teeth 22.

  Therefore, in order to fix the cylindrical body 48 as a plug to the radial arm 8 b, the teeth surround the circular portion 50 at the upper end, and more precisely, are partially inserted into the upper end gap 58.

  On the upper surface of the intermediate part 55, for example, a stopper 60 is provided which forms a pair of projecting elements 61 which are shown exactly in FIG. The stopper means 60 can prevent the cylindrical body 48 from rotating when the cylindrical body 48 as a plug is blocked in the curved teeth 22. In this case, the protruding element 61 is provided so as to surround the rectangular portion 51 at the upper end portion of the plug-type cylindrical body 48.

  FIG. 25 shows a part of the opening 49 provided in the body shell 7 so as to be able to cooperate with the cylindrical body 48 which is a plug according to this new embodiment.

  The opening 49 has an approximately eight shape having a main loop 49a and a sub loop 49b, and the diameter of the main loop 49a is larger than the diameter of the sub loop 49b.

  In addition, a substantially rectangular recess 62 having a function to be described later is provided around the sub loop 49b.

  When the plug-type cylinder 48 is firmly attached to the curved teeth 22 of the radial arm 8b, the user enters the main loop 49a of the opening 49 until the lower end surface 55a of the intermediate portion 55 comes into contact with the periphery of the main loop 49a and stops. The cylindrical body 48 is partially inserted. In this case, the diameter of the main loop 49 a is smaller than the diameter of the intermediate portion 55.

  After this partial insertion, the user advances the cylinder 48 into the secondary loop 49b. At this time, the periphery of the sub loop 49b comes into contact with the periphery of the lower end gap 59, and the plug is positioned as shown in the plan view of FIG.

  In this position, the rectangular recess 62 of the secondary loop 49b is advantageously arranged as a continuous part of the rectangular part 54 partially passing through the plug-type cylinder 48.

  Therefore, when the plug-type cylinder 48 is fixed in the secondary loop 49b, the rectangular recess 62 is formed between the parallelepiped cavity 57 of the pyramidal lower end portion 56 and the intermediate disk 55, more precisely, the pyramidal lower end portion. Positioned directly between the 56 circular base and the intermediate portion 55.

  A person skilled in the art will know the dimensions of the rectangular part 51, the position of the plug-type cylinder 48 and its direction in the radial arm 8b, the dimensions of the radial arm 8b, and the direction of the curved end 22 of the free end of the radial arm 8b. Accordingly, the position and dimensions of the rectangular recess 62 can be adapted.

  FIG. 28 is a perspective view of the block means, that is, the lock means 63 that can cooperate with the fixing means 47 of the fifth embodiment according to the present invention.

  The locking means 63 is in the form of a lug 64 having a cylindrical body 65, and the cylindrical body 65 has a circular plate 66 in the lateral direction at one of its ends, and a bulging portion 67 around it. The bulging portion 67 forms a parallelepiped element extending from the circular plate 66 with a length slightly smaller than the height defined by the cylindrical body 65.

  29 and 30 show two successive steps when inserting the block means 63 into the fixing means 47, respectively.

  As can be seen from these drawings, the bulging portion 67 has a shape that complements the rectangular portion 54 of the opening 52 at the upper end portion of the cylindrical body 48 that is a plug, and the cylindrical main body 65 also has a circular portion 53 of the opening 52. It has a shape that complements.

  Therefore, when the block means 63 is inserted into the cylindrical body 48, the parallelepiped bulging portion 67 is inserted into the parallelepiped cavity 57 formed in the lower end portion 56 of the plug 48 and penetrates the recess 62, Thus, the plug 48 can be locked at a predetermined position in the sub-loop 49b of the body shell 7.

  When the lug 64 is fully inserted into the opening 52, the lateral plate 66 is pressed against the upper end of the cylinder 48.

  The lug 64 is preferably made of plastic or rubber and is preferably connected to the cylinder 48, for example by a wire.

At the free end of the tongue 70, there is a sub-body 71 that is preferably substantially elliptical, and a rotating body 72 having a main body 73 is inserted into the sub-body 71. The rotating body 72 includes a tab 74 that can be gripped by an assembler in which the drive mechanism 1 is assembled to the body shell 7 on the upper end surface in the same plane as the bridge 70.

  The bridge 70 and the sub body 71 are made of a deformable material such as rubber, and the rotating body 72 is made of a hard material.

  Advantageously, the sub-body 71 has a shape that complements the internal space between the two side edges of the oval opening 69.

  Since the main body 73 of the rotating element 72 is elliptical and the secondary body 71 is formed of a deformable material, the secondary body 71 is also substantially elliptical.

  The substantially elliptical sub-body 71 has a main axis substantially equal to the maximum dimension between the two edges (69a, 69b) of the egg-shaped opening 69, so that the rotating body 72 is at the position shown in FIG. Only at certain times can the body 73 be inserted into the opening 69. That is, the tab 74 is formed as an extension of the bridge 70 and is the same as or parallel to the minor axis of the ellipse of the main body 73, and the main axis of the main body 73 is the two side edges 69 a of the oval opening 69. , 69b is parallel to or the same as the largest dimension portion.

  In order to fix the drive mechanism 1 to the body shell 7, the user first places the plug-type cylinder 16 in the main loop 29 a of the main opening 29 until the intermediate disk 18 stops in contact with the periphery of the main opening 29. Is partially inserted.

  By the translational operation, the plug-type cylindrical body 16 is engaged in the sub-loop 29b as described above.

  The sub-body 71 is engaged with the opening 69 so that the fixing means 68 can be locked.

  In order to block the sub-body 71 in the opening 69, the tab 74 is grasped and rotated in a clockwise or counterclockwise direction by an angle of 90 degrees (see FIG. 32). The maximum dimension of the body of the element is approximately the same as the distance between the two ends or tips of the oval opening 69.

  In order to block and support the sub-body 73 by friction and compression within the oval opening 69, it is beneficial that the distance between the two tips is slightly smaller than the main axis of the sub-body 73.

  33 and 34 are a perspective view and a side sectional view, respectively, of a fixing means 75 of a seventh embodiment according to the present invention for fixing a radial arm.

  According to this embodiment, the fixing means 75 comprises the plug-type cylindrical body 16 as described above, and the plug-type cylindrical body 16 is located at the same height as the intermediate disk 18 and the vertical axis of the cylindrical body 16. And a free end 76a of the tab is provided with an inclined portion 77 that can come into contact with the inclined portion 78 of the body shell 7.

  The body shell 7 has an opening 79 composed of a main opening 80 and a sub-opening 81.

In the sub-opening 81, the lower-end gap 21 is compressed due to the diameter difference between the lower-end gap 21 and the sub-opening 81.

  When the inclined portion 77 of the fixing tab 76 contacts the inclined portion 78 of the body shell 7, the fixing tab 76 is elastically deformed forward, and then the cylindrical body 16 is partially compressed in the sub-opening 81. The fixing tab 76 elastically returns to its initial position shown in FIG. 34, at which the inclined portion 77 is inserted into the main opening 80.

  At this time, the radial end edge 77a of the inclined portion 78 comes into contact with the edge on the opposite side to the main opening 80 and stops, so that the plug-type cylindrical body 16 comes out of the opening 79 by an unintentional releasing operation. Is prevented.

  The fixing means 14 for fixing the radial arm 8 to the body shell 7 comprises a plug-type cylinder 16 described with reference to FIGS. 3 and 4.

  When the cylindrical body 16 is partially inserted into the main loop 29a of the opening 29 and slid into the secondary loop 29b, the cylindrical body 16 is prevented from being detached from the secondary loop 29b due to unintentional movement. In addition, a locking means 83 that can be inserted into the main loop 29 a and locks the plug-type cylindrical body 16 is provided.

  This locking means 83 is composed of longitudinal pieces 84 each having curved lateral pieces 85 at both ends thereof.

  It is beneficial if the longitudinal piece 84 is slightly longer than the maximum free distance of the main loop 29a when the plug-type cylinder 16 is inserted into the secondary loop 29b.

  The longitudinal piece 84, more precisely the curved transverse piece 85, can abut on the one hand the plug-type cylinder 16 and on the other hand abut the circumference of the main loop 29a.

  Thus, the plug-type cylindrical body 16 cannot pass from the secondary loop 29b into the main loop 29a when the longitudinal piece 84 is inserted into the main loop 29a.
