Description

  The present invention relates to a mounting structure for a blind cap of a connecting part.

  The thing of patent document 1 is known as a blindfold cap for covering the head of the screw screwed in to a mounting base | substrate. In this conventional example, the blindfold cap has a locking string-like body that protrudes from the side edge portion of the head plate (lid main portion) and includes an arrow blade-shaped stopper at the tip.

The stopper portion can be elastically deformed, and is prevented from being detached from the mounting base of the blindfold cap by being engaged with an engagement opening formed in the recessed hole (accommodating recessed portion).
JP 2004-225738 A

  However, in the above-described conventional example, the blindfold cap is held on the mounting base only by the stopper portion that is elastically locked to the locking port, and thus has the following problems.

  That is, in order to increase the holding force of the stopper portion, it is necessary to increase the amount of elastic deformation during the locking operation of the stopper portion, but in this case, the operating force required for mounting increases and the operability deteriorates. In particular, when the blindfold cap is small, it is difficult to effectively apply the operation force, and hence the workability is further deteriorated.

  This problem can be solved by forming the locking string-like body from a flexible material. However, in this case, the lid main body is held in an upright posture or the like because the rigidity of the locking string-like body is reduced. Since it is difficult to keep the screw, there arises a problem that the screw tightening workability is deteriorated.

  The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a mounting structure for a blindfold cap of a connecting part that has a good workability for mounting a blindfold cap and has a high holding power to a mounting base. . Another object of the present invention is to provide a vehicle inside handle device to which the above mounting structure is applied.

  The connecting part 4 is formed with a receiving recess 3 for receiving a fixing element such as a screw, a rivet or the like, or a nut 2 such as a nut used for fixing to the mounting base 1, and the bottom wall of the receiving recess 3 is Used as a seating surface for screw heads.

  A blindfold cap 9 that covers the stator 2 in the mounted state and prevents exposure to the outside prevents the plate-like hinge leg piece 6 projecting from the lid main body portion 5 for closing the housing recess 3 from the wall surface of the housing recess 3 Is temporarily held by being latched in the latching opening 7 established in the above. On the side edge of the hinge leg piece 6 is formed a locking projection 11 that faces the locking step portion 10 formed in the locking opening 7 in the locked state, and is detached from the temporary holding state blind cap 9. When the separating force has a component force in the width direction of the hinge leg piece 6, the hinge leg piece 6 moves in the width direction and the locking projection 11 is formed on the side wall of the locking opening 7. Lock to the step 10.

  The blindfold cap 9 is preferably formed to have a rigidity capable of maintaining a temporary holding posture so as not to obstruct the connecting operation by unnecessarily closing the housing recess 3 during the fixing operation to the mounting base 1. After the connecting operation of the component 4 by the stator 2 is completed, the closing operation is performed.

  In the closing operation from the temporary holding state, the lid main body portion 5 is rotated in the thickness direction of the hinge leg piece 6 and the blind cap 9 or the locking claw 8 formed on the connecting component side is elastically applied to the other receiving portion. This is done by locking.

  It is extremely rare that only the detachment force that does not include the component force in the width direction of the hinge leg piece 6 acts on the blindfold cap 9 in the temporarily held state, and almost all the detachment force is considered to include the component force. Due to the lateral displacement of the hinge leg piece 6, the locking projection 11 is locked. Unlike the elastic locking portion, the locking projection 11 is not elastically locked in advance, or even if the locking dimension is very small, if the hinge leg piece 6 is displaced, a large locking force is generated. I can expect.

  As described above, in the present invention in which the locking projection 11 that does not increase the operating force during the locking operation is used as a resistance element against the detachment force, a large resistance to the detachment force with a light locking operation force. You can show your power.

The elastic locking of the hinge leg piece 6 to the locking opening 7 is formed by, for example, forming a locking element at the free end of the hinge leg piece 6 and bending it by inserting the locking element into the locking opening 7. Although it is possible to configure the locking element to be locked to the receiving portion by elastic return of the hinge leg piece 6,
The hinge leg piece 6 is temporarily held by locking a cantilever-like locking hook portion 12 formed by punching into a U-shaped central portion to the locking opening 7,
When the hook opening concave groove 13 is formed in the locking opening 7 so as to be approximately the same width as the locking hook portion 12 and provides a retreat space when the locking hook portion 12 is elastically deformed, the locking opening 7 Can be formed into a slit shape into which the hinge leg piece 6 is inserted. Since the hinge leg piece 6 inserted into the slit-like locking opening 7 has a limited degree of freedom of movement, the hinge leg piece 6 acts to effectively extract the width direction component force from the detachment force.

  Further, when the hinge leg piece 6 rotates around the width center line in the locking opening 7, the effective width dimension in the locking opening 7 of the hinge leg piece 6 (the locking opening corresponding to the wide surface of the hinge leg piece 6). 7) (the projection length of the width dimension of the hinge leg piece 6 on the wall surface) is shortened. As a result, the distance between the side edge of the hinge leg piece 6 and the locking step portion 10 is increased, and the locking dimension of the locking projection 11 is reduced. Get smaller. When the locking opening 7 is formed in a slit shape, the rotation angle around the width center line of the hinge leg piece 6 can be reduced, and the locking reliability of the locking protrusion 11 is improved.

  According to the present invention, it is possible to improve the mounting workability of the blindfold cap and to increase the holding force to the mounting base.

  FIG. 1 shows an embodiment of the present invention applied to an inside handle device 4 of a vehicle. The inside handle device 4 is formed by rotatably connecting a handle main body 15 to a handle base 16 fixed to an indoor side wall surface of a vehicle door.

  When the handle main body 15 is rotated in the direction indicated by the chain line from the initial rotation position indicated by the solid line in FIG. 1B while being fixed to the door, the engagement of the door lock device (not shown) connected to the door with a wire cable or the like is performed. The stop is released and the door can be opened. A lock knob 18 is connected to the handle base 16 by a rotary shaft 17 of the handle body 15 so as to be freely rotatable. The lock knob 18 maintains the door lock device in the locked state in the initial rotation posture shown in FIG. 1A, and cancels the unlocking operation when the handle body 15 is rotated.

  The handle base 16 configured as described above is fixed to the door panel (mounting base 1) by screws (stator 2) screwed into the door trim of the fixed piece 16a from the circular opening 16b opened in the center. In order to accommodate the head of the screw 2 screwed from the opening, the circular opening 16b is formed in the bottom wall of the housing recess 3, and in the housing recess 3 to cover the head of the screw 2 after mounting. A blindfold cap 9 is attached.

  As shown in FIG. 2, a cap support surface 16 c is disposed around the bottom wall of the housing recess 3 and is formed in an oval shape when viewed from the front. The cap support surface 16c is formed by a surface parallel to the surface of the handle base 16, and supports the rear peripheral edge of the lid main body portion 5 of the blindfold cap 9 described later.

  Further, in order to mount the blindfold cap 9, a locking opening 7 is formed on the front wall surface of the housing recess 3, and a hook receiving portion 3a is formed on the rear wall surface. In this specification, “front and back” is determined based on the state of FIG. 1A, and for convenience, “front and back” is “front” on the right side in FIG.

  The locking opening 7 is a rectangular opening having a height direction on the surface side from the boundary with the bottom wall of the housing recess 3 and long in the width direction in the direction of arrow V in FIG. At the boundary portion, a locking protrusion 7a is provided so as to protrude toward the front side and the front side over the entire length in the width direction. Further, as shown in FIGS. 2B and 2C, a hook passage groove 13 through which a locking hook portion 12 of a blindfold cap 9 to be described later can pass is provided at the center of the surface side wall surface of the locking opening 7. Is formed. Further, on the opposite two side walls of the locking opening 7, a locking step portion 10 is provided so as to project in the approaching direction.

  On the other hand, the blindfold cap 9 is formed by injection molding a hard synthetic resin material, and protrudes from one side edge of the plate-like lid main body 5 capable of closing the housing recess 3 of the handle base 16 as shown in FIG. A hinge leg piece 6 is provided, and a latching claw 8 that protrudes from the opposite side of the hinge leg piece 6 across the lid main body portion 5 in the rear surface direction. At the base end portion of the hinge leg piece 6, a V-shaped folded portion 6 a that protrudes in the back surface direction from the side edge of the lid main body portion 5 and is folded back to the front surface side is formed.

  In addition, a guide slope 14 is formed at the free end of the hinge leg piece 6 so as to gradually become narrower toward the tip, and a locking projection 11 projects from the vicinity of the start end of the guide slope 14. The A width direction dimension W between the locking protrusions 11 and 11 is formed so as to substantially match a dimension w between the locking step portions 10 and 10 of the locking opening 7.

  Further, a locking hook portion 12 is formed at the center portion of the hinge leg piece 6 in which a free end of a cantilever portion 6b formed by punching the periphery into a U shape is projected in a hook shape in the surface direction. .

  Therefore, in this embodiment, the blindfold cap 9 is temporarily held in the receiving recess 3 as shown in FIG. 4 by inserting the hinge leg piece 6 into the locking opening 7 as shown in FIG. Can do. The thickness dimension of the hinge leg piece 6 is substantially equal to the height dimension of the latching opening 7, and the insertion of the hinge leg piece 6 causes the latching hook portion 12 to abut against the latching protrusion 7a and further insertion. If the operation is continued, as shown in FIG. 5B, the cantilever portion 6b is elastically deformed and falls into the hook passage concave groove 13 of the locking opening 7 so that the hinge leg piece 6 can be inserted. When the hinge leg piece 6 is inserted, the guide slope 14 can pass through the hinge leg piece 6 when passing between the locking step portions 10 and 10 that are substantially equal to the interval between the locking projections 11 and 11 of the hinge leg piece 6. Guide to the position to prevent catching.

  If the hinge leg piece 6 is further pushed in from this state and the locking hook portion 12 gets over the locking protrusion 7a, the locking hook portion 12 is caused by the elastic restoring force of the cantilever portion 6b as shown in FIG. Is elastically locked to the locking protrusion 7a.

  In this state, the surface of the boundary portion between the V-shaped folded portion 6 a and the lid main body portion 5 comes into contact with the surface of the handle base 16. Since the blindfold cap 9 is formed of a material having an appropriate rigidity, the lid main body portion 5 maintains the standing posture shown in FIGS. 4 and 5C, the screw insertion into the circular opening 16b, and the screw 2 There is no hindrance to the fastening work.

  Further, a force in the detaching direction is applied to the blindfold cap 9, particularly the lid main body part 5 exposed to the outside in a posture in which the lid main body part 5 stands up, and the load is a component force that faces the width direction of the hinge leg piece 6. As shown in FIG. 5D, the entire blindfold cap 9 moves in the width direction. By the movement of the blindfold cap 9 to the side, the locking projection 11 is locked to the locking step portion 10 and is prevented from coming off.

  From the above state, the closing operation of the housing recess 3 after the operation of attaching the door panel 1 is completed, the lid main body portion 5 is rotated so as to push the V-shaped folded portion 6a, and the locking claw 8 is moved to the handle base 16 This is carried out by engaging with the hook receiving portion 3a. As shown in FIG. 1 (b), in the locked state of the locking claw 8, the lid main body portion 5 of the blind cap 9 is supported on the cap support surface 16c to be prevented from sinking and the V-shaped folded portion. 6a is elastically deformed along the wall surface of the locking opening 7, and continues to apply an urging force in the pushing direction to the lid main body portion 5 by an elastic restoring force.

  Further, since the side edge of the lid main body portion 5 where the locking claw 8 is disposed is a cut end surface by a straight line, a small gap is formed between the housing base portion 5 and the housing recess 3 in the mounted state. Is done. As a result, the blind cap 9 can be easily removed by inserting a sharp tool into the gap and prying it.
