Definitions

  • the present invention relates to a protective device adapting to a wood jointer, with a movable protective bridge arranged above the machine table and making it possible to cover the part of the tool-holding shaft located at the front. of the workpiece guide, means being provided for adjusting the height of the bridge for the passage of the wood to be planed and for allowing it to move vertically while remaining parallel to the table.
  • the present invention overcomes these drawbacks by providing a device providing great rigidity, a compact and simple construction, and good control of the automatic movement of the protective bridge in the vertical direction.
  • the protective bridge is held by an element comprising a straight guide in a substantially vertical direction, combined with a guide by at least two levers connected to each other. by at least one intermediate articulation axis, a lever being articulated by a movable axis to the bridge holding element and another lever being articulated by a fixed axis to a support integral with the frame of the jointer.
  • the device according to the invention is thus characterized by the combination of a rectilinear guide and a complementary guide by means of articulated levers, ensuring a connection between the mobile element which holds the bridge and a fixed support.
  • the protective bridge is fixed, by means of its holding element, at the top of a column movable vertically in a sliding guide belonging to the support integral with the frame of the jointer.
  • the levers may simply comprise a first lever articulated by a first axis either directly to the holding element of the protective bridge, or at the lower end of the column, and a second lever articulated to the first lever by a second axis and articulated to the aforementioned support by a third axis; the two levers thus form a "compass" arrangement.
  • the lever articulated by an axis to the bridge holding element and the lever articulated by an axis to the support integral with the frame of the jointer are linked together by means of two other levers articulated to the former, and constituting with these an articulated system like "deformable parallelogram".
  • the levers also allow easy control of the height adjustment of the protective bridge, by providing a rotary stop cam provided with an operating lever and cooperating with one of the aforementioned levers so as to limit the upward movement of the bridge. under the effect of a return spring.
  • This return spring of the bridge can be housed in the vertically movable column so as to tend to raise it with the bridge. he can also apply his effort, in the proper direction, on one of the levers or on one of the axes of articulation.
  • first lever (8) is articulated by a horizontal axis (9) to the column (5) - bridge (6) - intermediate piece (7) assembly.
  • the other end of the first lever (8) is articulated by a horizontal axis (10) to one end of a second lever (11), the second end of which is articulated by a horizontal axis (12) to the support (1).
  • a stop cam (14) is rotatably mounted on the support (1) around an axis (15) located inside the angle formed by the two levers (8,11).
  • An operating lever (16) integral with the cam-stop (14) allows its rotation control.
  • Figure 1 shows this stop cam (14) stopped in an angular position allowing adjustment of the protective bridge (6) in the low position.
  • Figure 2 shows the same stop cam (14) stopped in an angular position allowing adjustment of the bridge (6) in the high position.
  • a friction system disposed between the support (1) and the stop cam (14), maintains said stop cam in the angular position chosen.
  • the first lever (8) is articulated by the axis (9) to the intermediate piece (7) which serves to maintain the protective bridge (6), and the fixed articulation axis (12) connecting the second lever (11) to the support (1) is located below the axis (9), - near the column (5).
  • Various variants may relate to the position of the articulation axis (9) of the first lever (8) on the column (5) - bridge (6) - intermediate piece (7) assembly and the position of the axis of fixed articulation (12) of the second lever (11), as well as the angle formed by the two levers (8,11), as illustrated in FIGS. 3 to 6:
  • Figure 3 shows an embodiment in which the second lever (8) has its fixed axis (12) of articulation to the support (1) located at a point relatively distant from the column (5).
  • the variant of Figure 4 has the same feature with regard to the fixed axis (12), but the angle formed by the two levers (8, 11) is reversed.
  • the first lever (8) is articulated by the axis (9) at the lower end of the column (5) which projects under the guide part (4) of the support (1) .
  • the articulation axis (12) connecting the second lever (11) to the support (1) is here located above the aforementioned axis (9), near the column (5).
  • the fixed articulation axis (12) can be located at a point relatively distant from the column (5), as illustrated in FIG. 6.
  • articulated by the axis (12) to the support (1) are always articulated to each other by an axis (10), but they are also linked to each other by two other articulated levers (17,18) which form with the first levers (8, 11) a deformable parallelogram.
  • lever (8) articulated by the axis (9) to the column (5) - bridge (6) - intermediate piece (7) assembly is not directly articulated to the lever (11) articulated by the axis (12) to the support (1).
  • These levers (8,11) are linked to each other by means of two other articulated levers (19, 20) which form with the first a deformable parallelogram.
  • FIGS. 3 to 8 The operation of the various variants according to FIGS. 3 to 8 is identical to that of the device described in detail with reference to FIGS. 1 and 2.
