Description

  The present invention relates to an automobile door handle device that is applied to an inside door handle or the like of an automobile and the handle is rotatably supported by a shaft.

  As this type of automobile door handle device, there is one disclosed in Patent Document 1. As shown in FIGS. 4 and 5, the automobile door handle device 100 includes a base member 101 fixed to a door panel (not shown), a shaft 102 supported by the base member 101, and the shaft 102. A handle 103 inserted into the shaft hole 103a and supported rotatably about the shaft 102 as an axis, and a lock knob 104 similarly inserted into the shaft hole 104a and supported rotatably around the shaft 102 as an axis. I have.

  The handle 103 is connected to a door lock device (not shown), and in the closed position, the door lock device is located at the lock position and the door cannot be opened. When the handle 103 is rotated from the closed position to the open position, the door lock device is positioned at the unlock position and the door can be opened. The lock knob 104 is configured to maintain the door lock device in the lock position at the lock position, and the door lock device is not positioned at the unlock position even when the handle 103 rotates from the closed position to the open position. .

  By the way, the shaft hole 104a of the lock knob 104 is set to be large with respect to the outer diameter of the shaft 102 in consideration of operability. However, since the clearance between the lock knob 104 and the shaft 102 is generated in this way, the lock knob 104 is rattled in the direction of the arrow a in FIG. If the lock knob 104 is loose, the lock knob 104 interferes with the base member 101 or the like, or abnormal noise occurs.

In the conventional example, in order to prevent the lock knob 104 from rattling, the base member 101 is provided with a tongue piece 105, and the lock knob 104 is locked and unlocked at two positions by the elastic force of the tongue piece 105. Techniques have been proposed for pressing 104 against one of the shafts 102 in the axial direction. Here, since the handle 103 has a much longer dimension from the center of rotation to the free end than the lock knob, it is conceivable to apply the above technique to prevent the handle 103 from rattling in the direction of the arrow b in FIG.
JP 7-259393 A

  However, in the above-described rattling prevention means, since the handle 103 is pressed in one axial direction of the shaft 102, the handle 103 is installed at a position shifted in the axial direction with respect to the design reference position. Therefore, there is no problem with only one side of the free end side of the handle 103 being disposed close to the inner surface of the base member 101, but the entire circumference (both sides) of the free end side of the handle 103 is disposed close to the inner surface of the base member 101. As for the thing, a high assembly accuracy is required.

  SUMMARY OF THE INVENTION Accordingly, the present invention provides an automotive door handle device that can install a handle without causing a positional shift with respect to a design reference position, and that can ensure both prevention of the handle from rattling and good operability of the handle. With the goal.

  The invention according to claim 1, which achieves the above object, is a door handle device for an automobile in which a shaft supported by a base member is inserted into a shaft hole of the handle and the handle is rotatably supported around the shaft. The diameter of the shaft hole is set to be larger than the outer diameter of the shaft, and both end portions of the shaft hole are respectively formed with tapered portions that gradually increase in diameter toward the opening surface. Bushes are respectively interposed between the tapered portion and the outer peripheral surface of the shaft.

  The invention according to claim 2 is the door handle device for an automobile according to claim 1, wherein the bush has a cylindrical shape and is plastic, and an inner diameter before assembly is set smaller than an outer diameter of the shaft. It is characterized by that.

  According to the first aspect of the invention, the handle is supported by the shaft without clearance at the positions of the two bushes. In addition, since the bush is interposed at the position of the tapered portion of the shaft hole of the handle, the handle is supported only by a partial width of the bush, so that the sliding resistance when operating the handle can be kept small. The handle is installed without pressing force acting in the axial direction of the shaft. From the above, it is possible to install the handle without displacement with respect to the design reference position, and it is possible to ensure both prevention of the handle from rattling and good operability of the handle.

  According to the invention of claim 2, in addition to the effect of the invention of claim 1, when the shaft is inserted, the bush is plastically deformed, so that the handle is reliably secured without rattling in a part of the bush. Supported by

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment in which the door handle device for an automobile of the present invention is applied to an inside door handle, FIG. 1 is a front view of the door handle device 1 for an automobile, and FIG. 2 is a line AA in FIG. FIG. 3 is a sectional view before the shaft 3 is inserted into the shaft hole 14 of the handle 5.

  As shown in FIGS. 1 and 2, the door handle device 1 for an automobile includes a base member 2 fixed to a door panel (not shown), a shaft 3 supported by the base member 2, and a shaft 3. The lock knob 4 and the handle 5 are rotatably supported, and a spring (not shown) that biases the handle 5 toward the closed position.

  The base member 2 has a substantially elliptical outer peripheral edge portion 10, and a concave portion 11 that is loosely bent in a curved shape is formed inside the outer peripheral edge portion 10. The base member 2 is formed with shaft holes 12 along three straight lines at an upper end portion, a lower end portion, and an intermediate portion thereof.

  The shaft 3 is a cylindrical rod and is formed of a highly rigid metal material.

  The lock knob 4 is disposed at a lower position in the recess 11 of the base member 2. A shaft hole 13 is formed on one end side of the lock knob 4, and the shaft 3 is inserted into the shaft hole 13. The lock knob 4 is rotated between the locked position and the unlocked position with the shaft 3 as the center. The lock knob 4 locks the handle 5, prevents the handle 5 from moving from the closed position to the open position at the lock position, and allows the handle 5 to move from the closed position to the open position at the unlocked position.

  The handle 5 is disposed at an upper position in the recess 11 of the base member 2. A shaft hole 14 is formed on one end side of the handle 5, and the shaft 3 is inserted into the shaft hole 14. The handle 5 is rotated between a closed position and an open position with the shaft 3 as an axis center. In the closed position of the handle 5, the distal end side of the handle 5 is accommodated in the recess 11, and in the opened position of the handle 5, the distal end side protrudes outward from the recess 11. The handle 5 is connected to a door lock device (not shown). In the closed position, the door lock device (not shown) is located at the lock position, and the door cannot be opened. When the handle 5 is rotated from the closed position to the open position, a door lock device (not shown) is located at the unlock position, and the door can be opened.

  Further, both end portions of the shaft hole 14 of the handle 5 are respectively formed in tapered portions 15 that gradually increase in diameter toward the respective opening surfaces 5a. Bushes 16 are interposed between the outer peripheral surface of the shaft 3 and the tapered portion 15 of the shaft hole 14 of the handle 5.

  Each bush 16 has a substantially cylindrical shape, and includes a cylindrical portion 16a and a flange portion 16b integrally formed on one end side thereof. The cylindrical portion 16 a is set along the tapered portion 15 of the shaft hole 14 so that the inner diameter before assembly is set smaller than the outer diameter of the shaft. The flange portion 16 b is disposed on the aperture surface 5 a of the handle 5. Each bush 16 has plasticity, for example, is formed by impregnating a mesh-like copper material with fluorine resin having a low frictional resistance, and has a sliding resistance sufficiently smaller than that of the handle 5.

  Next, the dimension of each part of the shaft 3, the handle 5, and the bush 16 will be described. The diameter d1 of the shaft hole 14 of the handle 5 is set larger than the outer diameter d2 of the shaft 3. As a result, the handle 5 is not directly supported by the shaft 3. The inner diameter d3 before the assembly of the bush 16 is smaller than the outer diameter d2 of the shaft 3, and the outer diameter d4 is set to be substantially the same as the inner diameter of the tapered portion 15 of the shaft hole 14 of the handle 5. As a result, the handle 5 is supported by the shaft 3 without clearance at the position of the bush 16.

  Next, a procedure for assembling the lock knob 4 and the handle 5 will be described. As shown in FIG. 3, bushes 16 and 16 are temporarily assembled to the tapered portions 15 on both sides of the shaft hole 14 of the handle 5. Next, the lock knob 4 and the handle 5 are temporarily assembled in the recess 11 of the base member 2, and the shaft holes 12, 13, and 14 of these members are positioned on a straight line. Next, the shaft 3 is inserted into the shaft holes 12, 13 and 14 from the upper surface of the base member 2, and the tip of the shaft 3 is projected from the lower surface of the base member 2. A retaining ring 6 is attached to the tip of the protruding shaft 3. When the shaft 3 is inserted into the shaft holes 12, 13, and 14, the bushes 16 and 16 are expanded in diameter by the shaft 3 to fill the clearance between the outer peripheral surface of the shaft 3 and the tapered portion 15. The rattling of the handle 5 is eliminated.

  Next, the operation of the automobile door handle device 1 will be described. When the lock knob 4 is located at the lock position, the door lock device is not located at the unlock position even if an operating force is applied to rotate the handle 5 from the closed position to the open position. When the lock knob 4 is located at the unlock position, when the handle 5 is rotated from the closed position to the open position, the door lock device (not shown) can be unlocked and the door can be opened. When the operating force of the handle 5 is released, the handle 5 is rotated to the closed position about the shaft 3 by the spring force of a spring (not shown).

  Since the handle 5 rotated in this manner is supported by the shaft 3 without clearance at the positions of the two bushes 16 and 16, it is supported by the shaft 3 without play. Therefore, even when the entire periphery of the front end side of the handle 5 is arranged close to the outer peripheral edge portion 10 of the base member 2 as in this embodiment, the front end side of the handle 5 interferes with the outer peripheral edge portion 10 of the base member 2. There is nothing to do. Further, since the bush 16 is interposed at the position of the tapered portion 15 of the shaft hole 14 of the handle 5, in order to support the handle 5 with a partial width rather than the full width of the bush 16, that is, the minimum necessary width, Sliding resistance during operation can be kept small. The handle 5 is installed without any pressing force acting in the axial direction of the shaft 3. As described above, the handle 5 can be installed with no positional deviation from the design reference position, and both the prevention of the handle 5 from rattling and the good operability of the handle 5 can be ensured.

  In this embodiment, the bush 16 has a ring shape, and the inner diameter d3 before assembly is set smaller than the outer diameter d1 of the shaft 3, so that the bush 16 reliably supports the handle 5 in a partial width range.

  In this embodiment, the bush 16 is provided with the flange portion 16b, so that temporary assembly to the base member 2 is easy. Further, the sliding resistance between the handle 5 and the base member 2 can be reduced.

  In this embodiment, although the case where the automobile door handle device of the present invention is applied to the inside door handle is shown, the present invention is not limited to this. In addition, the present invention is preferably applied to a case where the length from the axial center to the free end is sufficiently long with respect to the axial length of the handle.
