Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a holder, and more particularly to a holder capable of absorbing variations in mounting height of an object to be mounted.

[0002]

[Prior art]

 For example, a part called a deck garnish is attached to the lower edge of the windshield of an automobile to guide the rainwater wiped off with a wiper to both sides. Conventionally, a holder HO made of a synthetic resin as shown in FIG. 5 has been used for the fixing. In this case, since the deck garnish (hereinafter, referred to as the object to be mounted 1) is a long object provided along the edge of the front glass and over substantially the entire width of the front glass, it is difficult to make the gap with the body side uniform. Therefore, when fixing the object to be mounted, if such variations in the height direction are not absorbed, problems such as floating will occur in some parts. For this reason, the holder is required to have a structure capable of arbitrarily adjusting the mounting height of the mounting target.

That is, as shown in FIG. 5, the holder HO comprises a holder main body 20 and an attachment tool 21 for pressing the attachment target 1, and the holder main body 20 has a body B on its lower surface. It has a retaining portion 22 for fixing to. In addition, a pair of left and right claw pieces 23a and 23b which are both flexurally deformable are provided on the upper side. On the other hand, a plurality of locking step portions 25 are engraved on the shaft portion 24 of the engaging member 21 along the height direction at a constant pitch, so that even if the height of the attachment target 1 varies, the holder body The claw pieces 23a and 23b of 20 can be engaged with either of the locking step portions 25. However, since the locking step portion 25 is formed for each pitch, if the height positions of the tips of both the claw pieces 23a, 23b are made uniform, there is a gap in the height direction. The rattle cannot be absorbed, resulting in the rattling in the height direction of the wearing target 1.

Therefore, conventionally, the height positions of the tips of both the claw pieces 23a and 23b are arranged so as to be slightly shifted in the vertical direction, and specifically, they are displaced by about 1/2 of the pitch of the locking step portion 25. Was set.

[0005]

[Problems to be solved by the device]

 However, as a result of arranging the positions of the tips of both the claw pieces 23a, 23b in the height direction, as a result, the engaging force (elastic force) received by the shaft portion 24 from the both claw pieces 23a, 23b is different in the vertical position. As a result, the entire attachment tool 21 may tilt due to this, causing rattling of the attachment target 1.

The present invention has been devised and devised in view of such a situation, and an object thereof is to provide a holder that can fix an object to be mounted in a good state.

[0007]

[Means for Solving the Problems]

 To achieve the above object, the structure of the present invention includes a head portion for pressing the upper surface of the mounting object and a plurality of locking steps formed so as to be inserted into the insertion holes of the mounting object and along the height direction. The fastener has a shaft portion in which each portion is engraved at a predetermined pitch, a fixing means to the body side and a recess capable of receiving the shaft portion, and the fastener is provided in the recess. And a retainer main body having a retainer main body formed with a pawl piece that can be selectively engaged with the locking step portion of the retainer main body. It is characterized in that three or more locking positions having different heights with respect to the stop step are arranged, and the respective locking positions have different phases within the pitch of the lock step. It

[0008]

[Action]

 Before fixing the attachment target to the body, first, the holder main body is fixed to the body side by the fixing means, and the shaft of the fastening member is inserted into the insertion hole of the attachment target. In this state, by fitting the shaft part of the attachment tool into the recess of the holder body and inserting it until the attachment target contacts the body, each claw piece engages with the corresponding locking step. To do. In this case, each claw piece exerts an engaging force on the shaft of the engaging device at at least three height positions. That is, since the shaft portion is supported by at least three points having different heights, the entire fastening device is held in an upright posture without tilting. At the same time, at least three locking positions have different phases within the pitch of the locking step portion, so that rattling of the pitch can be alleviated as compared with the conventional case.

[0009]

[Effect of device]

The effects of the present invention are as follows. Since the shaft portion of the fastening tool is supported by at least three points, it is possible to regulate the inclination of the fastening tool and fix the attachment target in a proper posture. Further, since the respective locking positions are dispersed in the positions having different phases, the rattling rattling can be alleviated and the rattling of the mounting object can be suppressed also from this point.

【Example】

 Embodiments embodying the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 1 is an automobile deck garnish (attachment target), and an insertion hole 4 through which a shaft portion 3 of an attachment tool 2 can be inserted is penetrated at a predetermined position, and the periphery thereof is attached. A counterbore 6 for accommodating the head 5 of the tool 2 flush with the wearing target 1 is provided in a circular recess.

The fastening tool 2 is composed of a head portion 5 for pressing the attachment target 1 and a shaft portion 3. In this embodiment, the fastening tool 2 is integrally formed of a synthetic resin material. Of these, a plurality of locking step portions 7 are engraved on the shaft portion 3 along the height direction. Each locking step portion 7 is composed of a mountain portion having a tapered ridge and a valley portion therebetween, and these are continuously formed at a constant pitch (P).

The holder main body 8 that constitutes the holder H together with the above-described fastener 2 is also integrally formed of a synthetic resin material like the fastener 2, and has a body B at the center of the lower surface of the substrate 9. A retaining portion 11 (fixing means) that can be elastically engaged with the mounting hole 10 is formed. The structure of the retaining portion 11 is well known in the art, and in this example, the horizontal cross section has a substantially S-shape, but if it can be fixed to the body B, that type is used. It doesn't matter. On the other hand, on both sides of the substrate 9, a pair of side pieces 12a and 12b stand upright over the entire width. The both side pieces 12a and 12b are provided with a predetermined rigidity so as not to be easily bent inward and outward, and the both side pieces 12a and 12b are provided with a recess 13 for receiving the shaft portion 3 of the fastening tool 2 therebetween. Holding and facing. Further, here, a total of three claw pieces 14a to 14c which can be selectively engaged with each locking step portion 7 of the shaft portion 3 are provided as follows.

That is, one claw piece 14a is located on one side 12a (right side in FIG. 2) of the both side pieces 12a, b from the position near the upper edge portion, and one claw piece 14a is located on the other side 12b (left side in FIG. 2). Two upper and lower claw pieces 14b and 14c are provided over the entire width at the edge and at a position slightly lower than the edge. Further, the height positions of the tips of the claw pieces 14a to 14c are different from each other, and the left and right sides are staggered. More specifically, as shown in FIG. 3, the height interval between the claw piece 14c having the lowest tip and the claw piece 14a having the middle tip is when the pitch of the locking step portion 7 is P. , P / 3. Further, the height interval between the middle claw piece 14a and the uppermost claw piece 14b is P + P / 3. That is, the locking positions of the claw pieces 14a to 14c with respect to the locking step portion 7 are such that the phases of the locking step portion 7 are shifted at substantially equal intervals.

The holder H of this embodiment is configured as described above, and when fixing the attachment target 1 to the body B, first, the retaining portion 11 of the holder main body 8 is attached to the body B. The holder main body 8 is preliminarily attached by pushing it into the attachment hole 10 and engaging it. On the other hand, when the shaft portion 3 of the attachment tool 2 is loosely inserted into each insertion hole 4 with respect to the attachment target 1 and the shaft portion 3 is fitted into the recess 13 of the holder body 8 and pushed in in this state, The shaft portion 3 is pushed in while bending the claw pieces 14a to 14c. In this case, since the heights of the tips of the claw pieces 14a to 14c are set to different positions, the claw pieces 14a to 14c can be engaged with each other even if the heights of the mounting target 1 and the body B vary. The corresponding one of the stop portions 7 is selected and engaged. Further, since the locking positions of the claw pieces 14a to 14c with respect to the locking step portion 7 are shifted in phase at substantially equal intervals, the rattling in the vertical direction is reduced as compared with the conventional case. Further, since the claw pieces 14a to 14c support the shaft portion 3 at three points, the inclination of the engaging member 2 is restricted and the claw pieces 14a to 14c are held in the upright posture. As a result, rattling of the attachment target 1 is suppressed, and the attachment target 1 is securely fixed.

In the above-described embodiment, three claw pieces 14a to 14c are provided, but as shown in FIG. 4, it is possible to provide four or more claw pieces. In the claw pieces 14d to 14g of FIG. 4, two pairs of left and right claw pieces are arranged vertically, and the height of the claw pieces in each group is 1 / 4P. The upper and lower groups are separated by 2P + 1 / 4P as shown in the figure.

In the structure as described above, since the fastening tool 2 is supported at four points, it is possible not only to prevent the fastening tool 2 from falling down, but also to grasp the claw pieces within one pitch of the locking step portion 7. Since the locking position of is more delicate than that of the above-described embodiment, it is possible to further suppress rattling in the vertical direction.

The engaging step portion of the engaging member may be replaced with a screw shaft, and the claw pieces may be opposed to each other on the left and right sides, or the holder main body may be formed into a cylindrical shape at an equal angle from the inner wall thereof. You may make it arrange | position each nail | claw piece in the radiation position of.
