TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mounting structure for a towing hook cover.
[0002]
[Prior art]
A towing hook is provided at the front end of the vehicle body, and an opening for passing a towing rope to be locked to the towing hook is formed in a bumper covering the towing hook. This opening is normally closed by a cover, and is removed from the opening only when the traction hook is used.
[0003]
In the opening of this type of structure, a pair of upper and lower insertion holes are respectively formed on both left and right edges, and a pair of upper and lower locking pieces and mooring pieces to be inserted into the insertion holes are formed on the cover side. .
[0004]
The locking piece has two-stage claws for locking and temporary holding. The mooring piece is long, has a guide portion inclined in the middle, and a stopper formed at the tip. Then, when the cover is first attached to the opening of the bumper before painting, the pawl for temporary holding of the locking piece is engaged with the insertion hole, and the bent portion on the tip side of the guide portion of the mooring piece is inserted into the insertion hole. , The cover is temporarily held at a position slightly outside the opening.
[0005]
The cover is brought into such a temporary holding state in order to make the side surface of the cover exposed. By simultaneously coating the cover and the bumper in the same process in such a temporary holding state, the same color as the bumper can be uniformly applied to the side of the cover hidden by the bumper in the same color tone.
[0006]
After painting, by pushing the cover into the opening, the locking claw of the locking piece engages with the insertion hole, and the bent portion on the base end side of the guide portion of the mooring piece engages with the insertion hole. The opening is closed by the cover.
[0007]
Then, when opening the opening and inserting the tow rope into the inside, first, the end on the side of the locking piece of the cover is pressed to be deformed inward, and the engagement between the locking claw of the locking piece and the insertion hole is released. . Then, while maintaining the deformation, the two-stage pawl formed on the locking piece is pulled out of the insertion hole while being careful not to interfere with the edge of the insertion hole, and the cover is rotated about the mooring piece.
[0008]
After rotation, the mooring piece is also pulled out of the insertion hole until the stopper at the tip engages with the insertion hole. Then, the cover is in an open state connected to the opening only by the mooring pieces, and the mooring rope can be inserted into the opening from the opened state and engaged with the towing hook (for example, see Patent Document 1). ).

[Problems to be solved by the invention]
However, in such a conventional technique, when the cover is opened, the engagement on one side of the locking side of the cover is pushed inward to release the engagement, and the cover is kept in a state where the end is deformed. , The operability of the cover is poor, and the cover may not be easily opened.
[0011]
The present invention has been made by paying attention to such a conventional technique, and provides a mounting structure of a towing hook cover that can easily open the cover.
[0012]
[Means for Solving the Problems]
According to the first aspect of the present invention, a cover is attached to an opening for a towing hook formed in a bumper, and a closed state in which the cover closes the opening is determined by an engagement state of the cover with the opening. With the mounting structure of the towing hook cover, an open state where it is removed from the opening with the part moored, and a temporary holding state where the cover is located slightly outside the opening with the side exposed Further, the cover is mounted so as to rotate about an intermediate portion by pressing one end in a closed state.
[0013]
According to a second aspect of the present invention, a shaft portion protruding into the opening while facing each other is formed at an intermediate portion between the pair of opposing edges in the opening, and a slit is formed near one edge other than the pair of opposing edges. Is formed, and a pair of support pieces, each of which has a groove cut out from the tip thereof, are protruded at positions corresponding to the shaft of the cover, and the groove is slid with respect to the shaft in a range from the closed state to the temporary holding state. Along with freely engaging, a bearing portion is formed on the base end side of the groove portion in which the shaft portion is rotatably held in a closed state, and at the other end of the cover opposite to the one end on the pushing side, A mooring piece that penetrates the slit is formed, and in the middle of the mooring piece, an elastic that engages with the outside of the slit in the temporary holding state and engages with the inside of the slit in the closed state, and that can pass through the slit by elastic deformation. Form a protruding part, and in the open state, Wherein the engaging of the inwardly to form a stopper for preventing falling off of the mooring element.
[0014]
The invention according to claim 3 is characterized in that the elastic convex portion has a hollow structure in cross section and generates a propulsive force in a passing direction by an elastic restoring force when passing through the slit.
[0015]
The invention described in claim 4 is characterized in that the stopper is formed on the same side as the elastic projection of the mooring piece, and in the temporary holding state, it is located inside the slit and is in elastic contact with the slit.
[0016]
The invention described in claim 5 is characterized in that the shaft portion and the support piece are formed at both left and right end portions, and the slit and the mooring piece are formed at the lower end portion.
[0017]
【The invention's effect】
According to the first aspect of the present invention, simply pressing one end of the cover in the closed state rotates the cover around the intermediate portion, and the other end of the cover projects outward from the opening. The user can hold the other end of the cover that has protruded by hand and remove the cover from the opening as it is to open the cover. Thus, since the operability when opening the cover is good, anyone can easily open the cover.
[0018]
According to the second aspect of the present invention, pressing the one end of the cover rotates the cover about the shaft. The cover removed from the opening after the rotation does not fall off from the opening because the stopper at the tip of the mooring piece engages with the slit, and is kept moored with the opening. When the cover is to be temporarily held in the opening of the bumper before painting, the groove formed in the support piece of the cover is inserted into the shaft of the opening and slid toward the opening as it is. The protrusion contacts the outside of the slit, and the cover is positioned in the temporary holding state. After the coating, if the cover is further pushed in, the elastic projections pass through the slits and become closed. In the closed state, the shaft portion is held in the bearing portion of the groove portion, and the elastic convex portion that has passed through the slit engages with the inside of the slit, so that a stable closed state is obtained.
[0019]
According to the third aspect of the present invention, in addition to the effect of the second aspect of the present invention, by pushing and rotating one end of the cover, the elastic projection passes from the inside to the outside of the slit. When the portion passes to the outside of the slit, the elastic restoring force of the elastic projection generates a thrust in the passing direction, so that the operation of rotating the cover can be performed easily and reliably.
[0020]
According to the fourth aspect of the invention, in addition to the effects of the second and third aspects, since the elastic projection is located inside the slit in the temporary holding state and elastically contacts the slit, the cover in the temporary holding state It is possible to perform reliable painting work without shaking.
[0021]
According to the fifth aspect of the invention, in addition to the effects of the second to fourth aspects, since the bent portion mooring piece is on the lower side, the open state is maintained by the gravity of the cover.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a bumper 1 on the front side of an automobile. An opening 2 is formed in the front of the bumper 1 and a cover 3 is attached thereto.
[0023]
As shown in FIG. 2, the opening 2 has a substantially rectangular shape, and a flange 4 is formed on the periphery thereof toward the inside. Further, a bent portion 5 is formed from the front end of the flange 4 toward the center of the opening 2 from the middle portion of the left and right edges of the flange 4 to the lower edge.
[0024]
In the bent portions 5 on both the left and right sides, the shaft portions 6 located exactly in the upper and lower portions of the opening 2 are formed so as to face each other. The portion of the shaft 6 protruding toward the opening 2 has a cylindrical shape.
[0025]
Further, a horizontally long slit 7 is formed in the lower bent portion 5. A rib 8 protruding rearward is formed on the lower edge of the slit 7, and the lower surface of the slit 7 is extended rearward by the rib 8.
[0026]
On the other hand, a flange 9 is also formed on the periphery of the cover 3, and the cover 3 itself has a shape having side surfaces. On the rear surface of the cover 3, support pieces 10 corresponding to the shaft portions 6 are provided on both right and left sides.
[0027]
A groove 11 is cut out from the tip of the support piece 10. The groove portion 11 is slidable with a predetermined friction with respect to the shaft portion 6, and a substantially circular bearing portion 13 is formed at a base end portion thereof via a narrow width portion 12. The bearing portion 13 has a size corresponding to the shaft portion 6 and can rotate with a predetermined friction while holding the shaft portion 6 inside.
[0028]
Further, a long mooring piece 14 is protrudingly provided at the lower end (the other end) corresponding to the slit 7 on the back surface of the cover 3. On the lower surface of the mooring piece 14, an elastic projection 15 having an arch-shaped hollow cross section is formed at an intermediate position. The portion of the mooring piece 14 ahead of the elastic projection 15 is formed to have a small thickness and is easily bent.
[0029]
On the lower surface of the mooring piece 14, an elastic piece-shaped first stopper 16 is formed slightly diagonally to the distal end side than the elastic projection 15 toward the diagonal base end side. A flaky second stopper 17 is also formed obliquely toward the proximal end side.
[0030]
Next, the engagement state of the cover 3 with the opening 2 will be described in order with reference to FIGS.
[0031]
Temporary holding state (Fig. 5):
The support piece 10 and the mooring piece 14 of the cover 3 are put into the opening 2 of the bumper 1 before painting, and the tip of the mooring piece 14 is first inserted into the slit 7. Then, the cover 3 is pressed toward the opening 2 as it is, and the shaft 6 is engaged with the groove 11 of the support piece 10 this time.
[0032]
After the shaft portion 6 enters the groove portion 11, the elastic convex portion 15 formed on the lower surface of the mooring piece 14 engages outside the slit 7, and the cover 3 is positioned at the temporary holding position. At the temporary holding position, the cover 3 exposes the side surface and is located slightly outside the opening 2. In this state, since the lower surface of the slit 7 is extended rearward by the rib 8, the terminal of the first stopper 16 does not fall out of the slit 7 and elastically contacts the lower surface of the slit 7.
[0033]
As described above, in the middle portion of the cover 3, the groove portion 11 of the support piece 10 comes into contact with the shaft portion 6 with a predetermined friction, and on the lower side of the cover 3, the elastic projection 15 engages with the outside of the slit 7 and Since the first stopper 16 elastically contacts the lower surface of the slit 7, even if the bumper 1 is passed through the coating process while the cover 3 is temporarily held, the cover 3 does not fluctuate. Painting work can be performed reliably. The cover 3 can be uniformly coated with the same color as the bumper 1 in the same color to the side.
[0034]
Closed state (Fig. 6):
After the coating, the cover 3 is pushed into the opening 2 to position the shaft 6 in the bearing 13 beyond the narrow portion 12, and the elastic convex portion 15 of the mooring piece 14 is passed through the slit 7 to Engage inside. By doing so, the middle portion and the lower end portion of the cover 3 are prevented from coming off, so that a closed state in which the opening 2 is securely closed by the cover 3 can be obtained.
[0035]
Rotation operation / initial (Fig. 7):
When the upper end (one end) of the cover 3 is pressed with a predetermined operating force F, the cover 3 starts rotating around the shaft 6 and the mooring piece 14 on the opposite side starts to be pulled out of the slit 7. The elastic projection 15 integral with the mooring piece 14 also enters the slit 7 and tries to pass through the slit 7.
[0036]
Rotation operation and final stage (Fig. 8):
When the top (center) of the projecting portion 15 passes through the slit 7 while the projecting portion 15 passes through the slit 7, the elastic restoring force of the projecting portion 15 causes the mooring piece 14 to move in the passing direction. Is generated, and the cover 3 automatically rotates. Therefore, the operation of rotating the cover 3 becomes easy and reliable. The cover 3 rotates until the distal end of the lower first stopper 16 hits the peripheral portion of the slit 7, and the lower end of the cover 3 largely projects outward from the opening 2.
[0037]
Detachment state from shaft part (Fig. 9):
Therefore, if the user pulls the lower end of the cover 3 that has largely protruded outward and pulls out the cover 3 while rotating the cover 3 downward, the shaft 6 comes out of the bearing 13 and the groove 11, and the cover 3 comes out of the opening 2. Come off. However, since the first stopper 16 of the mooring piece 14 is engaged with the outside of the slit 7, the cover 3 does not fall out of the opening 2 even when the hand is released from the cover 3.
[0038]
Open state (FIG. 10):
Only by releasing the hand from the cover 3, only the first stopper 16 is engaged with the slit 7, and only the elastic projection 15 falls into the corner of the flange 4 below the opening 2. 3 is further pulled downward to open the opening 2 largely open. Even in this case, since the first stopper 16 is engaged with the lower side of the slit 7 while bending, and the second stopper 17 is engaged with the upper side of the slit 7, the state in which the cover 3 is prevented from falling off is surely provided. Will be maintained. Further, since the mooring piece 14 is on the lower side, the open state of the cover 3 is maintained by the gravity of the cover 3 and the cover 3 does not return to the state in which the opening 2 is closed without permission. Then, the towing rope 18 is inserted through the opened opening 2 and is engaged with a towing hook (not shown) inside, so that the vehicle body can be towed. After towing, it can be returned to the closed state in FIG. 6 by an operation reverse to that described above.
