Description

  The present invention relates to a hole plug used, for example, for closing an opening formed in a plate-like member of an automobile.

  As a hole plug that closes the opening formed in the plate-like member, for example, a part of the insertion wall that is inserted into the opening is cut out, so that the tip side in the insertion direction of the hole plug is a cantilever shape. The thing in which the latching | locking part was formed is known. More specifically, the locking portion is configured such that a cantilever-shaped portion extending from the fixed end can be flexibly bent, and a locking claw protruding outward is formed on an outer surface of the locking portion. The hole plug is prevented from coming off by engaging the claw with the peripheral edge of the opening from the inner peripheral side (see, for example, Patent Documents 1 and 2).

  As described above, when the cantilevered locking portion is formed with the hole plug insertion direction front end portion as the fixed end, when the hole plug is inserted, the contact position between the locking portion and the periphery of the opening As the distance from the position of the fixed end of the locking portion is shorter, the locking portion is less likely to be elastically deformed. For this reason, for example, if the rigidity of the locking portion is increased in order to increase the locking reliability, it becomes difficult to insert the hole plug into the opening, damage to the hole plug, incomplete insertion, increase in work time, etc. Become.

  In view of the above points, an object of the present invention is to improve the ease of insertion into an opening and the like while ensuring the reliability of locking of a hole plug.

In order to solve the above problems, the present invention provides:
A hole plug for closing the opening inserted into the opening of the member to be inserted provided with an opening,
A head that closes the opening;
A leg standing on the head,
The legs are
A pair of columnar portions extending in the insertion direction of the hole plug from the head;
A connecting portion for connecting the tip portions of the columnar portions;
A locking piece that extends in the direction of the head from the coupling portion between the columnar portions and has a locking claw that is locked to the locking portion formed in the inserted member,
It is provided with.

  Thereby, when the hole plug is inserted into the opening, the columnar portion is mainly bent at the beginning, and the locking piece is bent as the insertion proceeds. Thus, the hole plug insertion operation can be facilitated by changing the portion that greatly deforms as the insertion of the hole plug proceeds.

  According to the present invention, it is possible to improve the ease of insertion into the opening and the like while ensuring the certainty of the locking of the hole plug.

It is a front view which shows the shape of a hole plug. It is a side view which shows the shape of a hole plug. FIG. 5 is a VV cross-sectional view of FIG. 3. It is VI-VI sectional drawing of FIG. It is VII-VII sectional drawing of FIG. It is VIII-VIII sectional drawing of FIG.

  Hereinafter, as an embodiment of the present invention, an example of a hole plug 100 that closes an opening 201a of a roof rail 200 attached to the roof of an automobile 300 as shown in FIG. 1 will be described. The opening 201 a is formed, for example, for inserting a bolt or a nut for fixing the roof rail 200 to the roof of the automobile 300.

  2 to 4, the hole plug 100 includes a head 101 that closes the opening 201 a of the roof rail 200, and a pair of legs 102 and 102 that are erected on the head 101, for example. ing. On the upper surface of the head 101, for example, an aluminum cover member 121 corresponding to the material of the roof rail 200 is attached via an adhesive member 122.

  Each of the leg portions 102 and 102 is a pair of columnar portions 103 and 103 extending from the head 101 in the insertion direction of the hole plug 100, and tip portions (lower end portions in FIG. 1 and the like) of the columnar portions 103 and 103. And a connecting portion 104 for connecting the two. Further, a locking piece 105 extending from the connecting portion 104 in the direction opposite to the insertion direction of the hole plug 100 (the direction of the head 101) is provided. That is, the locking piece 105 is formed in a shape defined by a U-shaped notch 102a whose lower side is open in the region of the leg 102 in the side view shown in FIG.

  The columnar portions 103 and 103 are formed, for example, at the base end portion on the head 101 side so that the thickness in the left and right direction in FIG. It is formed to be low. On the other hand, the distal end side of the columnar portions 103 and 103 has a cross-sectional shape that is bent in the direction in which the pair of leg portions 102 face each other as shown in FIGS. Further, the columnar portions 103 and 103 of the leg portions 102 and 102 protrude in the direction away from each other (left and right direction in FIG. 4) between the base end portion and the distal end portion of the columnar portions 103 and 103. Guide portions 103a and 103a are formed, and have higher rigidity than the base end portion. The setting of the rigidity distribution of the columnar portion 103 is not limited to the above, and may be performed by a combination of various cross-sectional shapes such as the thickness and width of the columnar portion 103.

  The guide portions 103a and 103a are positioned in the left-right direction in FIG. 4 when the hole plug 100 is inserted into the opening 201a. In addition, each columnar portion 103 is provided with an inclined portion 103b from the cross-sectional shape shown in FIG. 6 to the cross-sectional shape shown in FIG. 5, thereby facilitating insertion and positioning of the hole plug 100. It is like that.

  The locking pieces 105 of the respective leg portions 102 and 102 are formed with locking claws 105a projecting in opposite directions (outside sides) and insertion amount regulating portions 105c. Further, a locking recess 105b is formed between the locking claw 105a and the insertion amount regulating portion 105c, and a locking portion 202a (FIGS. 7 and 8) formed on the locking plate 202 of the roof rail 200 as will be described later. ). In the vicinity of the central portion in the width direction of the locking claw 105a and the insertion amount restricting portion 105c, a concave portion 105d / 105e is provided so as to suppress a decrease in shape accuracy due to so-called sink when manufacturing the hole plug 100. It has become.

  As shown in FIGS. 7 and 8, the roof rail 200 into which the hole plug 100 is inserted is provided so as to be separated from the upper plate 201 having the opening 201a and the upper plate 201, thereby forming a locking portion 202a. The locking plate 202 and the base plate 203 formed with the bolt holes 203a are arranged in the vertical direction.

  For example, a bolt (not shown) protruding from the roof of the automobile 300 is inserted into the bolt hole 203a of the base plate 203, and a nut inserted from the opening 201a is screwed to fix the roof rail 200 to the roof of the automobile 300. It has come to be. The hole plug 100 is fixed to the roof rail 200 by fitting the engagement recess 105 b of the engagement piece 105 of the hole plug 100 into the engagement portion 202 a of the engagement plate 202. That is, when the locking claw 105 a of the locking piece 105 is engaged with the locking portion 202 a of the locking plate 202, the hole plug 100 is prevented from coming off, while the locking piece 105 is formed on the upper surface of the locking plate 202. The hole plug 100 is prevented from falling into the opening 201a by the contact of the insertion amount regulating portion 105c. Note that the method for restricting the insertion amount of the hole plug 100 is not limited to the method in which the insertion amount restricting portion 105c is brought into contact with the upper surface of the locking plate 202. If the positional relationship accuracy with the stop plate 202 is appropriately maintained, the insertion amount can be easily maintained while the hole plug 100 is reliably locked.

  When the opening 201a of the roof rail 200 is closed by the hole plug 100 as described above, the following operation is performed.

  When the lower end of the leg portion 102 of the hole plug 100 starts to be inserted into the locking portion 202 a of the locking plate 202, the base end portion of the locking piece 105 from the contact position between the locking plate 202 and the locking piece 105. Since the distance to the connecting portion 104 is relatively short, even if the hole plug 100 is pushed in while the inclined portion of the locking piece 105 contacts the locking portion 202a of the locking plate 202, the locking piece 105 itself The displacement due to deflection is relatively small. On the other hand, the distance from the contact position between the locking plate 202 and the locking piece 105 to the base portion of the head portion 101 which is the base end portion of the columnar portion 103 is relatively long, and the rigidity of the base end portion is Since it is set low, the displacement of the leg part 102 due to the deflection of the base end part of the columnar part 103 becomes relatively large. Therefore, the hole plug 100 can be inserted relatively easily.

  Eventually, when the insertion amount of the hole plug 100 increases, the distance from the contact position of the locking plate 202 and the locking piece 105 to the base portion of the head portion 101 that is the base end portion of the columnar portion 103 is now increased. It becomes relatively short. For this reason, even if the rigidity of the base end portion of the columnar portion 103 is set to be low, the displacement of the columnar portion 103 can be suppressed small. On the other hand, since the distance from the contact position between the locking plate 202 and the locking piece 105 to the connecting portion 104 that is the base end portion of the locking piece 105 is relatively long, the displacement due to the deflection of the locking piece 105 itself is small. It becomes relatively large. Therefore, the hole plug 100 can be inserted relatively easily.

  As described above, there are a plurality of portions that elastically deform and act like fulcrums, and the portion that greatly deforms as the insertion of the hole plug 100 changes, so that the rigidity of the entire leg portion 102 is set low. Without failing, it is possible to easily ensure the locking reliability, to facilitate the insertion work of the hole plug 100, to easily prevent the hole plug 100 from being damaged or not completely inserted, and to reduce the work time. .

  In the above example, an example in which a pair of leg portions 102 is provided has been described. However, since the operation mechanism as described above of each leg portion 102 is independent, the number is not limited to one pair. More than one leg 102 may be provided. Moreover, the direction of engagement of each locking piece 105 is not limited to the opposite direction side, and may be, for example, a radial direction along the circumference.

  Further, the member to be inserted is not limited to the roof rail 200, and any member having various openings may be used.
