Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a screw receiver used when a screw is fixed to a metal panel, and in particular, the present invention relates to a mounting hole formed in the panel. The present invention relates to an improved screw receiver that is effective when it is buried in the coating material when it is attached to the vehicle and then coated for the purpose of preventing corrosion.

[Prior Art] Conventionally, a screw receiver used when screwing to a panel is widely known. In particular, it is indispensable when fixing parts to a body mainly made of a metal panel such as an automobile, and many screw receivers are used.

Generally, a screw receiver has a collar 20 and an insertion leg 21 that hangs from the lower surface of the collar as shown in FIG. 9, and a vertical screw receiving hole is provided from the upper surface of the collar toward the center of the insertion leg. Then, the insertion leg is pushed into the mounting hole to be drilled in the panel A so that the lower surface of the collar comes into contact with one surface of the panel, and the locking claw 22 provided on the outer surface of the insertion leg is engaged with the edge of the mounting hole. It is fixed and mounted on the panel, and then screwed into the screw receiving hole to be fixed and then mounted.

The shape of this screw holder varies depending on the place of use,
Basically, it has a common structure, and by rubbing the screw into the screw receiving hole, the insertion leg is expanded and the engaging force with respect to the mounting hole is increased, and the locking force of the screw with respect to the panel is increased. ing.

By the way, although this screw receiver is used in many places, it is necessary to open a mounting hole in the panel for its use as described above. This mounting hole may be opened before painting the surface of the panel, but it may be opened after painting. In this case, it is necessary to coat it after attaching the screw receiver in order to prevent corrosion. Further, depending on the location, a screw receiver may be attached at a predetermined position on the pre-setting panel, and parts may be attached using the screw receiver as needed. In this latter case, there is a case where it does not prevent the screw receiver from being exposed, but there is a case where the flange portion exposed on the surface is coated and buried due to a problem in appearance or the like.
For example, a case where a screw receiver is attached to a fender and used for attaching a car fender liner is one example.

When the flange portion exposed on one surface of the panel is covered with paint after mounting the screw receiver in this way, the screw receiving hole is buried as shown in FIG. The position of is unknown and screwing becomes difficult.

[Problems to be Solved by the Invention] In the present invention, after mounting a screw receiver in a mounting hole of such a panel and then burying the surface by coating, a fender liner is particularly mounted. Considering the case where it is buried by being applied thickly like coating with PVC sol like a screw receiver for
It is devised for the purpose of easily and quickly confirming the mounting position of the screw receiving member, particularly the opening position of the screw receiving hole, through the coating layer after the coating process so that the screwing operation can be performed quickly and reliably.

[Means for Solving Problems] The present invention has been made based on the above-mentioned object, and is characterized by a collar that abuts on one surface of the panel and a panel that is hung from the lower surface of the collar and attached to the outer surface. While having an insertion leg provided with a locking claw that locks in the hole and a screw receiving hole vertically formed from the upper surface of the collar toward the insertion leg, the opening of the screw receiving hole is formed on the upper surface of the collar. The present invention is to provide a screw receiver having a guide projection of a required height standing around the above.

[Operation] In the screw receiver of the present invention, the insertion leg is inserted into the mounting hole of the panel so that the brim is brought into contact with one surface of the panel, and the locking claw provided on the outer surface of the insertion leg is locked in the mounting hole for mounting. Then, when the surface of the collar is buried by applying a coating material such as PVC sol to the panel surface next, push up the coating material of the part with the guide protrusions standing from the upper surface of this collar and raise it. It represents the position of the buried screw receiving hole.

Hereinafter, the features of the present invention will be described in detail through the embodiments shown in the drawings.

[Embodiment] FIG. 1 is a side view of a screw receiver according to the present invention, FIG. 2 is a front view, FIG. 3 is a plan view, FIG. 4 is a bottom view, and FIG. The front view and FIG. 6 are sectional views taken along line VI-VI in FIG.

The screw receiver is integrally formed of thermoplastic synthetic resin. In this embodiment, the collar 1 and the collar 1 are formed in a circular umbrella shape.
On the other hand, main components are an insertion leg 2 formed in a substantially square prismatic cross-sectional shape that hangs from the lower surface of the, and a screw receiving hole 3 that is vertically drilled from the center of the upper surface of the collar 1 along the center of the insertion leg 2. A guide projection 4 standing upright from the upper surface of the collar 1 is added to the screw holder of the present invention.

The insertion leg 2 is provided with a vertical shallow groove 6 on two front and rear surfaces of the four outer surfaces 5 facing each other, and a door-shaped locking claw 7 is extended from one vertical edge of the groove 6, and the locking is performed. The horizontal upper edge 7a of the claw 7 and the lower surface of the collar 1 are opposed to each other.

The locking claw 7 constantly projects its free end out of the outer surface 5, and by this projection the upper edge 7a is faced to the lower surface of the collar 1, so that the insertion leg described later is inserted into the mounting hole a of the panel A. Is bent inward at the edge of the mounting hole and retracted into the groove 6 so that the mounting hole can be easily passed. In addition, this insertion leg has a tapered tip to facilitate insertion into the mounting hole.
Along with this, the locking claw 7 is also notched obliquely at the lower edge so that it can be automatically retracted at the time of insertion.

The screw receiving hole 3 is formed in a round hole having a diameter slightly smaller than the shaft diameter of the tapping screw B to be screwed in to allow the screw to be bited. On the other hand, in this embodiment, the screw receiving hole 3 is directed from the inner wall surface toward the four corners of the insertion leg 2. A vertically elongated slit 8 is provided to facilitate the expansion of the diameter when screwing in and allow the insertion leg 2 to expand.
The opening 3a of the screw receiving hole 3 that opens on the upper surface of the flange is tapered so that the screw can be easily inserted.

The guide projection 4 indicates the position of the opening 3a of the screw receiving hole 3. Here, two thin columns 9 are erected from the upper surface of the collar 1 with the opening of the screw receiving hole 3 interposed therebetween. An annular body 10 is integrally formed so as to extend between the upper ends of the above and surround the opening 3a.

The rising height of the guide projection 4 is selected according to the thickness of the coating material to be applied at the place where the screw receiver of the present invention is used. It is desirable that it does not hinder the screwing of.

Now, the screw holder of the present invention configured as above is the panel A
The insertion leg 2 is inserted into the mounting hole a which is drilled, and the locking claw 7 is hooked on the edge of the mounting hole a, and at the same time, the lower surface of the collar 1 is brought into contact with the surface of the panel A, whereby the panel is mounted. After the mounting, when a coating agent such as vinyl chloride sol is applied to the surface of the panel to form the coating layer C, the flat collar 1 is embedded and the screw receiving hole 3 opened therein is coated. The guide projection 4 standing up from the upper surface of the collar 1 so as to surround the opening 3a pushes up the coating layer and raises it 11 along the guide projection 4 as shown in FIG. The position of the opening 3a of the hole 3 becomes immediately apparent.

Therefore, if the screw B is pressed against the guide protrusion and kneaded with an appropriate tool such as a screwdriver, the screw can be easily screwed without removing the opening 3a.

Of course, if the attached object 12 such as the fender liner is screwed by this screwing, the pillar 9 of the guide protrusion 4 is bent as shown in FIG. 8 by tightening the screw, so that the conventional screw tightening is possible. Becomes

[Effects of the Invention] As described above, the screw receiver of the present invention enables a screw to be fixed to the panel, and also has a coating material to cover the surface of the panel or to bury the screw receiver itself. When applied, the guide protrusions standing upright from the upper surface of the collar push up this coating layer or raise a part of the coating layer surface to expose the coating layer surface to open the screw receiving hole 3 at the opening 3a. Because of the pointing, the screw can be easily screwed in on this aim, so that there is no obscure presence and no interruption of work due to the embedding as in the screw holders that were commonly used in the past. .

In addition, since the screw receiver of the present invention is mainly composed of the flexible support column 9, when the object to be mounted is screwed, this support column does not interfere with the tightening of the screw and the conventional screw support is not impaired. The tightening is exactly the same as the tool.

Furthermore, when this screw receiver is not used, a small ridge is left on the surface of the coating layer, but since it is exposed only slightly, it does not damage the appearance at all, so it can be used as a screw receiver for screwing automobile fender liners, etc. Is optimal.

In the description of the embodiment, the annular body of the guide projection is an endless one, but if it is sufficient to infer the center position pointed by this projection, that is, the opening of the screw receiving hole, the ring cut in the middle May be Further, the description has been given based on the shapes of the flange 1 of the screw receiving tool, the inserting leg 2 and the screw receiving hole 3 individually specified. However, the sectional shape of the inserting leg, the shape of the locking claw, and the screw receiving hole are provided. It does not prevent changing the slits and the like to other shapes.
