TECHNICAL FIELD OF THE INVENTION
The present invention relates to an end structure of an outer tube in which a wire member is inserted.
[0002]
[Prior art]
For example, as an operation force transmission structure in a vehicle body of an automobile, an outer tube having both ends fixed between an operation portion and an operated portion is routed, and a wire member for transmitting the operation force is passed inside the outer tube. There is something like that. Both ends of the outer tube are formed by cylindrical plugs, and these plugs are held near the operation section and the operated section. The outer tube itself is not connected to the operating part or the operated part, but merely forms a path for the wire member.It is the internal wire member that is actually connected to the operating part and the operated part to transmit the operating force. is there.
[0003]
In such an operating force transmitting structure, the direction of the wire member extending from the plugs at both ends of the outer tube and connected to the operating portion or the operated portion is defined as a direction in which the operating force acts on the operating portion or the operated portion. , Depending on their structure (for example, the direction of rotation of the rotary lever). Therefore, the direction of the plug serving as the outlet of the wire member also needs to be held straight along the wire member so as not to increase the operation resistance (for example, see Patent Document 1).
[0004]
If there is an obstruction in the path of the wire member between the operating part and the operated part, the plug is held at a different angle from the wire member to be taken out to bypass the obstruction. However, even in such a case, the other part is bent toward the detour path while the outlet part of the plug is kept straight with respect to the wire member. By doing so, a large increase in operation resistance is prevented.

[Problems to be solved by the invention]
However, in such a conventional structure, the outer tube of the stage as a part before mounting is bent at both ends because the outer shape of the plug itself is curved in order to bypass the obstructive structure. This is inconvenient when bundled as parts and stored or transported. Further, since the wire member is stored in a bent state inside the plug in the outer tube, if the storage is performed for a long time, the wire member may be bent.
[0007]
The present invention has been made by paying attention to such a conventional technique, and it is possible to take measures against detour without curving the outer shape of the plug itself, and to provide an outer tube that does not bend the wire member in the plug without load. An end structure is provided.

[0014]
【The invention's effect】
According to the first aspect of the present invention, the plug has an angle different from that of the wire member extending from the plug and can take a path bypassing the obstructive structure only after the plug is attached. Since the outer tube is not bent, it is convenient to store and transport the outer tube in a bundled state at the stage of the outer tube as a component before mounting. Even if the angle of the plug is different from that of the wire member extending from the plug, an inclined surface in the direction corresponding to the angle of the wire member is formed near the outlet of the wire member in the inner passage of the plug, There is no significant increase in resistance.
[0015]
According to the second aspect of the present invention, the inner passage of the plug has a shape capable of storing the unloaded wire member in a straight state, and the inclined surface in a direction corresponding to the angle of the wire member.

Therefore, by changing the insertion direction of the plug with respect to the notch, the plug can be connected to the wire member. The angle can be reversed, so that it is possible to cope with left-right differences when applied to automobiles.
[0019]
According to the invention described in claim 6, even if the operated portion moves like the latch plate of the movable rail in the tilt angle adjusting device for the seat back, the effect of the preceding claim can be obtained without change.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view of a right side wall 1 in a vehicle traveling direction at a rear portion of a vehicle body, as viewed from a vehicle interior side. A rear seat back 2 is supported on the floor below the side wall 1 so as to be pivotable back and forth about a pivot point S. The rear of the seat back 2 is a luggage compartment R, and the luggage compartment R can be enlarged by moving the seat back 2 forward.
[0021]
A lock 3 is provided at an end of the seat back 2 on the side wall 1 side. A fixed rail 4 is provided on a side wall 1 corresponding to the lock 3. The fixed rail 4 has a curved shape corresponding to the forward and backward movement locus of the lock 3, and is fixed to the side wall 1 via the front leg bracket 5 and the rear leg bracket 6. The fixed rail 4 has a plurality of latch holes 7 (FIG. 4) arranged in the front-rear direction.
[0022]
A movable rail 8 is slidably engaged with the fixed rail 4. Two latch holes 9 corresponding to the latch holes 7 of the fixed rail 4 are also formed on the upper surface of the movable rail 8. A U-shaped striker 10 protruding toward the seat back 2 is fixed to the movable rail 8.
[0023]
Above the movable rail 8, a latch plate 13 as a "operated portion", which is rotationally biased by a spring 11 so that one latch claw 12 is engaged with the latch holes 7, 9, is rotatably supported. I have. The position of the movable rail 8 is fixed to the fixed rail 4 by the latch claws of the latch plate 13 being engaged with the latch holes 7 and 9 of the movable rail 8 and the fixed rail 4. The other of the latch plates 13 is a lever 14 for applying an operating force.
[0024]
The movable rail 8 is formed with a holding piece 15 as a “holding part” projecting downward. A notch 16 is formed in the holding piece 15, and a hook 17 for retaining is formed at one of the entrances of the notch 16. In addition, a concave portion 18 is formed at the innermost bottom of the notch 16.
[0025]
An operation unit 19 is provided near the lower end of the seat back 2 on the side wall 1. An outer tube 20 is routed between the operation section 19 and the latch plate 13 of the movable rail 8 which is the “operated section”. The outer tube 20 is routed not in a straight line but in a curved state toward the front side because a disturbing structure G that does not preferably interfere with the outer tube 20 exists below the fixed rail 4.
[0026]
Both ends of the outer tube 20 are respectively formed by cylindrical plugs 21 and 22 made of resin. A groove 23 (FIG. 6) is formed in the plug 21 on the operation portion 19 side in the circumferential direction, and is inserted into a holding portion (not shown) of the operation portion 19 and held. The plug 22 on the latch plate 13 side is fixed to the end of the outer tube 20 in a state where the plug 22 is tightened by the metal tube 24 as shown in FIG. The head 25 of the plug 22 has a substantially elliptical shape with both ends slightly projecting, and has a groove 26 formed obliquely to the longitudinal direction of the plug 22. Protrusions 27a and 27b that can be engaged with the recesses 18 of the cutouts 16 are formed at opposing positions in the middle of the oblique groove 26 (see FIGS. 8 and 9).
[0027]
The internal passage 28 of the plug 22 basically has a structure in which a straight hollow portion communicating with the outer tube 20 is secured, and an inclined surface 28a (FIG. 10) is formed only near one of the outlets. The inclined surface 28a is formed at a portion corresponding to the lowest position of the groove 26 formed obliquely. As described above, the outer shape of the two plugs 21 and 22 is basically the same even if the groove portions 23 and 26 are formed on the side surface, or the inclined surface 28a is formed inside one plug 22. It has a straight shape.
[0028]
A metal wire member 29 is inserted into the outer tube 20 having such a structure. The wire member 29 is longer than the outer tube 20, and both ends of the wire member 29 protrude from plugs 21 and 22 at both ends of the outer tube 20. The end of the wire member 29 on the operation section 19 side is an L-shaped hook 29a, and the end on the latch plate 13 side is a ball 29b.
[0029]
The plugs 21 and 22 constituting both ends of the outer tube 20 are straight in shape, including the plugs 21 and 22 at both ends, at the stage of parts before being attached to the vehicle body, so that the outer tubes 20 are bundled and stored, It is convenient for transportation. In addition, even in the plug 22 on the movable rail 8 side, the inner passage 28 is basically a straight hole shape and a structure in which only the inclined surface 28a is added thereto. The member 29 is maintained in a straight state without being bent, and the wire member 29 does not bend even if the parts are stored for a long period of time.
[0030]
When such an outer tube 20 is attached to the side wall 1 of the vehicle body, the plug 22 on the lower side of the outer tube 20 is previously attached to the operation section 19, and most of the outer tube 20 is put into the vehicle interior. In this state, the operation section 19 is attached to the back side of the side wall 1 together with the outer tube 20.
[0031]
Then, the upper plug 22 of the outer tube 20 is extended toward the movable rail 8 and inserted into the cutout 16. The plug 22 is inserted so as to engage with both edges of the notch 16 from the oblique groove 26 in a direction in which the lower part thereof is inclined forward by the angle θ (FIG. 3). When the plug 22 is inserted, the hook 17 prevents the notch 16 from coming off.
[0032]
At the same time as the insertion, the convex portion 27a of the plug 22 engages with the concave portion 18 formed at the bottom of the notch 16, rotation of the plug 22 in the notch 16 is prevented, and the posture of the plug 22 with respect to the notch 16 is maintained. You. In the maintained posture, the inclined surface 28a of the inner passage 28 of the plug 22 is in a forward facing state. Therefore, the inclined surface 28a always corresponds to the wire member 29.
[0033]
Then, the ball 29a, which is the end of the wire member 29 taken out from the plug 22, is extended and connected to the lever 14 of the latch plate 13. The wire member 29 extended from the plug 22 has a right angle to the rotation axis of the lever 14 in a state where the holding piece 15 and the lever 14 are straightly connected so as to effectively transmit the rotating force. To
[0034]
Accordingly, the groove 22 is inclined with respect to the wire member 29 taken out, so that the lower portion thereof and the upper portion of the outer tube 20 continuous therefrom have different angles from the wire member 29. , It is possible to bypass a disturbing structure G which is inclined forward and located below the movable rail 8.
[0035]
When the operating portion 19 is pushed and operated from the vehicle interior side, the operating force is transmitted to the lever 14 of the latch plate 13 via the wire member 29 in the outer tube 20, and the lever 14 is acted upon by the force of the spring 11. 5, the latch claw 12 of the latch plate 13 is disengaged from the latch hole 7 of the fixed rail 4, and the movable rail 8 engages the striker 10 with the lock 3 of the seat back 2, as shown in FIG. The slide can be performed in a state where the slide is performed.
[0036]
Then, when the operator releases the operating portion 19, the latch plate 13 is again engaged with the latch hole 7 of the fixed rail 4, the movable rail 8 is fixed again at that position, and the seat back 2 is moved to the position of the movable rail 8. The angle will be adjusted accordingly. Further, by operating another release button (not shown) provided on the seat back 2, the engagement between the lock 3 and the striker 10 is released, and as shown in FIG. The luggage compartment R can be enlarged by separating the luggage compartment from the front and moving it forward.
[0037]
When the angle of the seat back 2 is changed, the wire member 29 that moves inside the outer tube 20 for transmitting the operation force has a different angle from the plug 22 when it comes out of the plug 22. Since the inclined surface 28a in the direction corresponding to the angle of the wire member 29 is formed near the outlet in the passage 28, the operation resistance of the wire member 29 does not increase significantly.
[0038]
In this embodiment, since the projections 27a and 27b are formed at both sides of the groove 22 of the plug 22, the present invention can be applied to the case where the plug 22 is attached to the left and right opposite side walls 1. That is, in FIGS. 1 and 2, the plug 22 is inclined to the left while facing the side wall 1 because of the structure applied to the right side wall 1 in the vehicle traveling direction. It is necessary to incline the plug to the right while facing the side wall, but since the convex portion 27b is formed on the opposite side, the same structure can be used as it is as a right and left hand.
[0039]
In the above embodiment, the outer tube 20 attached to the side wall 1 of the vehicle body has been described as an example. However, the present invention is not limited to the vehicle body itself, but may be applied to an outer tube used for a vehicle body accessory such as a seat assembled to the vehicle body. It is possible.
