[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automobile antenna which has a simple structure and can be operated from the room with a small operation force, and more particularly to a manual operation mechanism for the same.

[0002]

[Prior art]

 There are motor-operated and magnet-operated rod antennas for radio reception installed in automobiles, but there are also many types in which the antenna is extended and retracted manually. As shown in FIGS. 9 and 10, the conventional manually-operated antenna stores the upper portion 18 of the antenna 1 in the ornament 92 provided along the pillar 91 of the automobile when the antenna is stored, and only the antenna head 19 is stored. Expose. Then, as shown in the sectional view of the ornament part of FIG. 11, the antenna head 19 abuts on the upper end opening 921 of the ornament 92 to prevent the antenna 1 from descending.

A seal member 93 made of rubber or the like is provided on the upper part of the ornament 92 to prevent rainwater and the like from entering and the antenna 1 descends by its own weight due to its frictional force and elasticity when the antenna is extended. To prevent it. The extension and storage of the antenna 1 are carried out either by temporarily getting out of the passenger compartment or by reaching out from the window and operating the antenna head 91 or the antenna upper part 18 by hand. As an improved version of the above-mentioned outside-operated manual antenna, there is also known an indoor-operated manual antenna in which a manual raising / lowering operation mechanism is provided in the passenger compartment (Japanese Patent Laid-Open No. 49-127546, Shokai Sho). 59-14405).

[0004]

[Problems to be solved]

 However, the conventional manually operated antenna has the following problems. That is, in the case of the operation method outside the vehicle, it is necessary for an occupant to open the door glass and put out his / her arm, or to operate after getting out of the vehicle once. The operability is very bad, and there are problems such as getting wet in the rain. In addition, there is a problem that the hands are dirty because the antenna is operated directly by hand.

On the other hand, in the indoor operation type, although the above problem does not occur, the antenna is held by the sealing material 93 provided on the upper portion of the ornament as described above, and the antenna is prevented from being lowered due to its own weight. Therefore, there is a problem that the operation is heavy. On the other hand, if the gripping force of the sealing material is weakened and the operating force is lightened, there is a problem that the antenna easily falls due to its own weight. Another problem was that the sealing material deteriorated and the gripping force of the antenna weakened. In view of such conventional problems, the present invention intends to provide an antenna operation mechanism which can be manually operated from the passenger compartment, has a small operation force, and is free from the possibility of spontaneously descending due to the weight of the antenna.

[0006]

[Means for solving the problem]

 The present invention provides an antenna that is slidable along a pillar of an automobile, a knob that moves the antenna up and down in the interior of the pillar, and a guide plate that has a sliding groove that guides the movement of the knob. The vehicle antenna according to the invention is characterized in that at least one knob locking portion is provided in the sliding groove of the guide plate.

That is, a knob for vertically operating the antenna is attached to the antenna. Further, a guide plate is provided along the vertical direction of the pillar in the vehicle compartment, and the guide plate is provided with a sliding groove for guiding the movement of the knob. The sliding groove has a length matching the elevation distance of the antenna. Then, the head of the knob is projected to the passenger compartment side of the guide plate, and the antenna is arranged on the opposite side (pillar side) of the guide plate. Then, for example, when the knob is at the lower end of the sliding groove, the head of the antenna is arranged so as to descend to the upper end of the storage ornament outside the vehicle.

Further, the sliding groove of the guide plate is provided with an engaging portion of the knob. The locking portion is provided at the knob position when the antenna is lifted to the maximum, but an appropriate number may be provided at an intermediate position within the lifting range of the antenna. There are various kinds of locking methods for the above-mentioned locking part, such as a side groove to prevent the knob from descending and a constricted part to elastically grip the knob.

In the present invention, the knob preferably has a lock mechanism for locking the knob locking portion. As a result, the antenna can be locked more reliably. As such a lock mechanism, for example, there is one using a spring and a lock pin (see FIGS. 3 and 4).

[0010]

[Action and effect]

 In the present invention, the antenna mounted on the antenna is moved up and down along the sliding groove of the guide plate to raise and lower the antenna. That is, when the knob is at the lower end of the sliding groove, the antenna descends to the lower limit, and when the knob is operated to the upper end of the sliding groove, the antenna rises to the upper limit. When holding the antenna at a desired position, the knob is locked to the knob locking part. Therefore, the antenna does not descend due to its own weight.

Therefore, in the passenger compartment, the elevation of the antenna can be manually operated and the antenna can be held at a desired position. In addition, since the knob locking part is provided in the sliding groove, it is not necessary to provide a seal member to prevent the antenna from falling due to its own weight unlike the conventional example. Therefore, the resistance of the sealing member disappears when the antenna is operated, and the lifting force of the antenna is significantly reduced compared to the conventional example.

[0012] Since the seal member is eliminated, rainwater and the like enter along the antenna rod, but it does not matter if the inside of the pillar is naturally dropped. Therefore, according to the present invention, it is possible to provide an automobile antenna that can be manually operated in the vehicle compartment, has a small operation force, and is free from the possibility of being lowered due to the weight of the antenna.

The inner guide plate 42 is provided with a plurality of knob locking portions 45. Further, the knob 2 is provided with a lock mechanism having a lock pin 21 that is fitted into and disengaged from the knob locking portion 45, and a coil spring 22.

Further, as shown in FIGS. 3 and 4, the knob 2 has a nut hole 12 formed in a lower end portion 11 of the antenna 1 into which a thin screw portion 23 provided at a tip end of the knob 2 is inserted, and a nut 121 Is stopped by. Further, the outer guide plate 31 and the inner guide plate 32 are provided with a plurality of mounting holes 313 and 323 each having a screw thread, and both guide plates are joined by a joining bolt 33.

As shown in FIGS. 3 and 4, the knob 2 has a head portion 24, a lock pin 21, a central shaft portion 25, and a thin screw portion 23, and a coil spring 22 is provided in the central shaft portion 25. . The length of the center shaft portion 25 is formed to be the same as the distance held between the inner guide plate 32 and the outer guide plate 31. On the other hand, the groove widths of the sliding grooves 41, 42 are formed to be smaller than the diameter of the head portion 24 of the knob 2 and slightly larger than the diameter of the center shaft portion 25. Further, the inner guide plate 32 is provided with a plurality of circular locking portions 45 having a diameter larger than the groove width along the sliding groove 42.

Further, the diameter of the lock pin 21 of the knob 2 is formed to be slightly smaller than the groove diameter of the locking portion 45 so that the locking pin 21 can be fitted into and removed from the locking portion 45. The inner guide plate 32 and the outer guide plate 31 are integrated by a connecting bolt 33, and are attached to the pillar so that the outer guide plate 31 is on the indoor side. The antenna 1 is arranged outside the inner guide plate 32, and is screwed to the knob 2 as described above.

Further, the center shaft portion 25 of the knob 2 is inserted and arranged in the sliding grooves 41 and 42 of the guide plates 31 and 32. The head portion 24 of the knob is assembled so as to extend above the outer guide plate 31. The coil spring 22 provided on the center shaft portion 25 is brought into contact with the lower surface of the outer guide plate 31. As a result, the lower surface of the head 24 of the knob 2 is pressed against the upper surface of the outer guide plate 31 by the urging force of the coil spring 22. A washer 29 is provided between the coil spring 22 and the head 24 to smooth the sliding of the knob.

Further, as shown in FIG. 2, the antenna 1 expands and contracts toward the outside of the vehicle from the opening 921 at the upper end of the ornament 92 as in the conventional example. In this example, as shown in FIG. 5, the sealing material unlike the conventional example is not used at the tip of the ornament (compared with FIG. 11).

Next, the function and effect will be described. First, when the antenna is locked, the lock pin 21 of the knob 2 is fitted into the locking portion 45 of the sliding groove to lock the vertical movement of the knob 2 in the groove direction. Further, when operating the antenna 1, the knob head 24 is pulled inward. As a result, the coil spring 22 is compressed, the lock pin 21 is disengaged from the locking portion 45, and the knob can be slid along the sliding grooves 41 and 42. Therefore, the knob 2 is operated up and down along the sliding groove 41 to move the antenna 1 up and down.

When the elevation of the antenna 1 is stopped and the knob 2 is released from the hand at the position where the lock pin 21 and the locking portion 45 are engaged, the lock pin 21 is pushed by the urging force of the coil spring 22. Then, it is fitted into the locking portion 45. Therefore, the antenna 1 is retained. Therefore, compared with the conventional gripping of the antenna by the sealing material, the locking of the antenna is more reliable, and there is no fear of the gripping force decreasing due to deterioration of the sealing material over time.
