[0002]
[Prior art]
As a conventional vehicle corner pole device of this type, a housing incorporating a drive mechanism including a rope transfer pinion, a telescopic telescopic pole that is detachably attached to a pole mounting portion of the housing, and a telescopic telescopic pole A rope with a rack in which one end is coupled to a part of the telescopic pole so that the pole can be expanded and contracted, and the other end is led to the vicinity of the pinion in the housing, and a rack portion of the rope with the rack is connected to a tooth portion of the pinion A rope guide mechanism for restricting the rope transfer path to mesh with the light emitting body, a light emitting body such as an LED attached to the distal end portion of the telescopic pole so as to be visible from the outside, and one end connected to the light emitting body Leads through the rope to the other end of the rope, and is connected to the end of the lead and extends and contracts. When Lumpur is extended operation, there is one and a contactor as attached to the other end of the rope to be electrically connected in contact with the power supply terminals in the housing.
[0003]
[Problems to be solved by the invention]
The conventional vehicle corner pole device has the following drawbacks. Normally, the contact attached to the other end of the rope is formed of a metal material having a larger diameter than the outer diameter of the rope and a large rigidity. For this reason, the rope restricting member for meshing the rack portion of the rope with the tooth portion of the pinion is a rope guide mechanism having a structure fixed to the housing so as to form a certain gap portion with the pinion. The contact cannot pass through the gap in the rope guide mechanism. For this reason, for example, when the telescopic pole is replaced, even if the telescopic pole is pulled out together with the rope, the contactor is caught at the position where the rope restricting member is provided. I could not.
[0004]
If a rope guide mechanism having a structure in which a rope restricting member is elastically held by a spring or the like is used with respect to the housing, the contact can pass through the gap, so that the rope can be pulled out. . However, since the load on the entire telescopic pole including the rope is considerably large, the structure as described above causes the rope to separate from the pinion when the telescopic pole is extended, and slip occurs.
[0005]
One means for solving such a problem is, for example, as disclosed in Japanese Utility Model Publication No. 4-12832. In the car corner pole device disclosed in the above publication, one end of a cord guide made of a flexible member provided with a drive cord guide portion at the free end is fixed to the pole assembly, and the pole assembly is disposed on the housing side. When the pole assembly is mounted on the housing, the drive cord is attached to the drive gear by providing a guide wall that abuts the free end of the code guide and curves the code guide toward the drive gear. Are provided so as to be engaged with each other.
[0006]
In the above apparatus, when the pole assembly is removed from the housing, the cord guide is also removed together, so that the engagement between the drive cord and the drive gear is released, and the pole assembly can be pulled out of the housing. However, this device has the following problems. That is, since the cord guide is integrated with the pole assembly, there is a problem that the mounting operation when mounting the pole assembly to the housing becomes very complicated. In particular, when the pole assembly is mounted on the housing, it is necessary to insert the cord guide while curving it from a straight shape. Therefore, the insertion resistance is large and a strong force is required for the insertion. Moreover, since it is necessary to fix against a strong repulsive force, it is necessary to provide a strong fixing means so that the fixing can be surely performed.
[0007]
Accordingly, an object of the present invention is to provide a vehicle corner pole device as described below.
(a) A vehicle corner pole device that can mount a pole assembly including a rack-equipped rope having a contact at an end to a housing or pull it out to the outside as needed.
(b) A corner pole device for a vehicle that is very simple to mount the pole assembly on the housing and does not require complicated operations.

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
FIG. 1 is a side view showing a partially broken configuration of the vehicle corner pole device according to the first embodiment of the present invention.
[0010]
Reference numeral 10 denotes a housing in which a driving mechanism including a rope transfer pinion 12 and the like is accommodated. A pole mounting portion 11 having a bottomed cylindrical shape is provided on the side wall of the housing 10, and a pole assembly 20 is detachably mounted from an upper end opening thereof.
[0011]
The pole assembly 20 has a telescopic telescopic pole 21 and one end thereof coupled to a part of the telescopic pole 21 (such as the tip portion of the smallest diameter pole) so that the telescopic pole 21 can be telescopically operated. A rope 22 with a rack guided to the vicinity of the pinion 12 in the housing 10, a light emitter 23 such as an LED attached to the tip (top) of the telescopic pole 21 so as to be visible from the outside, and the light emitter 23 One end of which is connected to the other end of the rope 22 through the rope 22 and the other end of the rope 22 is connected to the end of the lead 24 and the telescopic pole 21 extends. When operated, the contact 2 made of an elastic metal member attached to the other end of the rope 22 so as to be in electrical connection with a power supply terminal (not shown) in the housing 10. It is equipped with a door.
[0012]
The telescopic pole 21 accommodates a plurality of pipes 21a, 21b,... Having different diameters that are slidably connected to each other in the outer cylinder 21x.
Inside the housing 10, a rope guide mechanism 30 is provided for restricting the rope transfer path so that the rack portion of the rack-equipped rope 22 meshes with the tooth portion of the pinion 12. The rope guide mechanism 30 includes an operating rod 31 that responds to a change in the mounting position of the pole assembly 20 with respect to the specified position Lo of the pole mounting portion 11, a cam 32 that is rotated by the pressing force of the operating rod 31, The cam 32 includes a return spring 33 (such as a coil spring) that returns the cam 32 to its original position when the pressing force of the operation rod 31 is released.
[0013]
Thus, in the rope guide mechanism 30, when the pole assembly 20 is not mounted, the telescopic pole 21 is in a state of being separated from the specified position Lo of the pole mounting portion 11 of the housing 10 by a certain distance (L 1 −Lo) or more. At this time, the cam 32 is rotated so that the rope 22 is kept free with respect to the pinion 12. When the pole assembly 20 is mounted, when the telescopic pole 21 approaches a predetermined distance (L1 -Lo) or less with respect to the specified position Lo of the pole mounting portion 11, the rope 22 is moved according to the approach distance. The cam 32 is rotated as indicated by a broken line so as to approach the pinion 12 and change the degree of meshing between the rack portion of the rope 22 and the tooth portion of the pinion 12.
[0014]
FIG. 2 is a perspective view of a main part showing a detailed configuration of the rope guide mechanism 30. 3A and 3B are a front view and a side view showing the structure of the operating rod 31. FIG. 4A and 4B are a top view and an end view showing the structure of the cam 32, respectively.
[0015]
As shown in FIG. 2, the cam 32 is pivotally supported at the center by a shaft 34. A lever 35 is integrally formed in the base end portion of the cam 32 in parallel with the shaft 34. One end of the lever 35 is pulled upward in the figure by a return spring 33 made of a coil spring or the like. Therefore, the cam 32 is always given a rotational biasing force as indicated by a solid arrow around the shaft 34.
[0016]
Therefore, now, in order to mount the pole assembly 20 to the housing 10, when the outer cylinder 21x of the telescopic pole 21 is inserted into the pole mounting part 11 and the bottom of the outer cylinder 21x is lowered to the level L1, the bottom is It abuts on the upper end of the operation rod 31. Therefore, when the outer cylinder 21x is further pushed down to the specified position Lo with the mounting force Po, the operation rod 31 is pushed downward accordingly. As the operating rod 31 is pushed in, the lower end of the operating rod 31, that is, the operating end 31a formed as shown in FIGS. 3A and 3B, moves down from the level L11 to the level L10, and the lever 35 is moved. Press. Then, the lever 35 rotates and displaces as shown by a broken line 35 ′ in FIG. 2 while resisting the pulling force of the return spring 33. Along with this, the cam 32 rotates around the shaft 34 as indicated by a broken line arrow in FIG. And the groove part provided in the outer peripheral surface of the front-end | tip part of the cam 32, ie, the circular arc-shaped groove part 32a formed so that it might fit to an outer periphery of a rope as shown to (a) (b) of FIG. Is pressed against the pinion 12 side. As a result, the rack portion 22 a of the rope 22 with rack meshes with the tooth portion 12 a of the pinion 12. Therefore, the outer cylinder 21 x of the telescopic pole 21 is screwed to the pole holding portion 11 with the fixing screw 13.
[0017]
When a drive mechanism (not shown) is operated in this state, the binion 12 rotates in a predetermined direction, so that the rope 22 with rack is transferred in the longitudinal direction. For this reason, the telescopic pole 21 is extended or reduced. When the telescopic pole 21 is in an extended state, the contact 25 attached to the end of the rope 22 comes into electrical contact with a power supply terminal (not shown). Therefore, power is supplied to the light emitter 23 via the lead wire 24, and the light emitter 23 is turned on.
[0018]
In order to replace the pole assembly 20, after removing the fixing screw 13, when the pole assembly 20 is pulled out from the pole mounting portion 11 of the housing 10 with a force P 1, the pressing force to the operation rod 31 is released. Therefore, the cam 32 is automatically returned to the original position by the return force of the return spring 33. As the cam 32 returns, the upper end of the operating rod 31 rises from level Lo to level L1, the lower end of the operating rod 31 rises from level L10 to level L11, and the cam 32 returns to the position indicated by the solid line. For this reason, a sufficiently large space is generated between the cam 32 and the pinion 12 which are rope regulating members. Therefore, not only the rope 22 but also the contact 25 having a larger diameter and larger rigidity than the rope 22 can pass through without any problem. Thus, the pole assembly 20 can be easily pulled out.
[0019]
(Modification)
The vehicle corner pole device shown in the embodiment includes the following modifications.
-The telescopic pole is not a telescope type, but applied to a device that simply moves the single pole up and down.
-A telescopic pole with a light emitter other than LED attached to the tip.
・ A light-emitting body that can be lit other than when the telescopic pole is fully extended.
-A cam with a friction reducing means such as a lubricant or a rotating roller added to the tip of the cam.
[0020]
(Summary of embodiment)
[1] The vehicle corner pole device in the embodiment is
When the pole assembly 20 is not mounted at the specified position Lo in the pole mounting portion 11 of the housing 10, the cam 32 so that the rope 22 with a rack for pole expansion and contraction operation is kept free with respect to the rope transfer pinion 11. When the pole assembly 20 is mounted at the specified position Lo of the pole mounting portion 11, the rope 22 is brought close to the pinion 12, and the rack portion 22a of the rope 22 is moved to the pinion 12. A rope guide mechanism 30 for rotating the cam 32 so as to mesh with the tooth portion 12a is provided.
[0021]
In the above apparatus, in a state where the pole assembly 20 is not mounted on the pole mounting portion 11 of the housing 10, the rope 22 with a rack for pole expansion / contraction operation is kept free with respect to the rope transfer pinion 12. That is, the rope 22 and the pinion 12 are in a disengaged state. For this reason, not only the lobe 22 itself, but also the contact 25 having a larger diameter and larger rigidity than the rope 22 attached to one end of the rope 22 has a gap between the pinion 12 and the cam 32 as a rope regulating member. It will be possible to pass through. Therefore, the pole assembly 20 including the rope 22 can be attached to the pole attaching portion 11 of the housing 10 or pulled out to the outside as necessary. When the pole assembly 20 is mounted on the pole mounting portion 11 of the housing 10, the rope 22 is sufficiently pressed against the pinion 12. For this reason, the rope 22 and the pinion 12 are stably transferred by the pinion 12 without causing a slip. The rope guide mechanism 30 is separated from the pole assembly 20 and is fixedly installed on the housing 10 side. For this reason, the mounting operation when mounting the pole assembly 20 to the housing 10 is extremely simple, and no complicated operation is required.
[2] The vehicle corner pole device according to the embodiment is the device according to [1], wherein the rope guide mechanism 30 is operated in response to a change in the position of the pole assembly 20 with respect to the specified position Lo of the pole mounting portion 11. It comprises a rod 31, a cam 32 that is rotated by the pressing force of the operating rod 31, and a return spring 33 that returns the cam 32 to its original position when the pressing force by the operating rod 31 is released. It is characterized by.
[0022]
In the above apparatus, the cam 32 is automatically rotated to the original angular position by the return force of the return spring 33 in the state in which the external force with respect to the operation rod 31 is removed, in addition to the same effect as [1]. It returns and the meshing of the rope 22 and the pinion 12 is released. For this reason, when the pole assembly 20 is attached or detached, it is only necessary to insert or pull out the pole assembly 20 including the rope 22, and there is no need to perform any other special operation. Accordingly, the mounting or pulling-out operation of the pole assembly 20 can be performed very easily. The force required for mounting the pole assembly 20 is only the force that rotates the cam 32 against the pulling force of the return spring 33. Therefore, the insertion resistance into the housing 10 is small, and the pole assembly 20 can be easily attached to the housing 10. Further, since the repulsive force from the rope guide mechanism 30 in the mounted state is small, the fixing means of the pole assembly 20 can be simplified.
[3] The vehicle corner pole device according to the embodiment includes:
A housing 10 including a drive mechanism including a rope transfer pinion 12, an extendable pole 21 detachably attached to the pole mounting portion 11 of the housing 10, and one end thereof so that the extendable pole 21 can be extended and retracted. A rope 22 with a rack that is coupled to a part of the telescopic pole 21 and the other end is led to the vicinity of the pinion 12 in the housing 10, and a rack portion 22 a of the rope 22 with the rack is used as a tooth portion 12 a of the pinion 12. A rope guide mechanism 30 for restricting the rope transfer path to be engaged, a light emitter 23 attached to the tip portion of the telescopic pole 21 so as to be visible from the outside, and one end connected to the light emitter 23 and the other end Leads through the rope 22 to the other end of the rope 22 and the end of the lead 24 When connected and the telescopic pole 21 is extended operation, and a contact 25 attached to the other end of as the rope 22 which electrically conductive contact with the power supply terminal of the housing 10,
The rope guide mechanism 30 is configured so that the rope 22 is free from the pinion 12 when the telescopic pole 21 is separated from the specified position Lo in the pole mounting portion 11 of the housing 10 by a predetermined distance (L1 -Lo) or more. When the cam 32 is rotated so as to maintain a stable state and the telescopic pole 21 approaches a predetermined distance (L1 -Lo) or less with respect to the specified position Lo of the pole mounting portion 11, the rope according to the approaching distance. And the cam 32 is rotated so as to change the degree of meshing between the rack portion 22a of the rope 22 and the tooth portion 12a of the pinion 12.
[0023]
In the apparatus, the same effect as [1] can be obtained, and by adjusting the approach limit distance of the telescopic pole 21 with respect to the specified position Lo of the pole mounting part 11, the rack part 22a of the rope 22 and the pinion 12 can be obtained. It is possible to variably set the degree of meshing with the tooth portion 12a. As a result, the meshing state can be adjusted and set to an optimum state according to the wear state of the cam 32 and the like.
[0024]
