Description

[0001]
BACKGROUND OF THE INVENTION
The present invention mainly relates to a clip removal tool for easily removing a clip that fixes an automobile lining or the like.
[0002]
[Prior art]
When installing or repairing power windows, or when repairing sheet metal due to an accident, etc., it is necessary to remove the decorative plate attached to the inside of the door or back gate, generally called lining.
[0003]
The lining is fixed to the body panel via a clip as shown in FIG.
In order to remove the lining 6 from the body panel, it is only necessary to remove the clip from an attachment hole provided in the body panel. As a tool to be extracted, a clip removing tool 120 as shown in FIG.
[0004]
The clip removal tool is a tool in which a rod-shaped shaft provided with a plate-shaped thin wall portion having a U-shaped fitting groove at one end is inserted into a grip used for a driver or the like. As shown in FIG. An offset portion 126 is provided and bent in a substantially square shape around 1/3 from the tip, and the clip is pulled out by the lever principle with this bend as a fulcrum.
[0005]
The general size of such a clip removing tool has a total length of about 200 mm and an axial length of about 100 mm.
[0006]
As shown in FIG. 7, the clip has a plate A43 and a plate B44 for fixing to the lining, a wedge-shaped elastic engagement portion 42 inserted into a hole provided in the body panel, and this elastic engagement portion 42. And an umbrella-shaped plate 41 sandwiching the body panel, and a plate A43 and a plate B44 for fixing to the lining.
[0007]
The clip mounting hole 5 in the lining 6 has a bowl-like shape composed of a hole 51 slightly larger than the plate A43 of the clip and a hole 52 slightly larger than the diameter of the clip shaft portion. After being inserted into the hole 51, the clip 4 is fixed to the lining 6 by sliding the constricted part of the hole 51 and the hole 52 into the smaller hole 52 through the constriction.
[0008]
In order to pull out the clip 4 from the hole in the body panel, the forked portion U-shaped groove 121 of the clip puller 120 is inserted into the groove 45 between the umbrella-shaped plate 41 and the plate A43, and the bending of the shaft 123 is used. It was done by lever operation.
[0009]
However, the shape of the vehicle itself is various, and of course, the shape of the lining, its attachment state, and the surrounding environment are also various. For example, as shown in FIG. In some cases, the lining 6 is more securely fixed using a clip.
[0010]
Although the clip 4 used for the outer periphery 61 of the lining 6 can be removed by a conventional clip removing tool, the length of the shaft portion of the conventional removal tool is short for 62 clips 4 per lining center portion. After that, the clip 40 could not be reached, and even if it could be reached, it could not be removed because the lever operation could not be performed in the limited space between the body panel and the lining.
[0011]
In such a case, instead of removing the lining by removing the clip from the body panel mounting hole, the lining itself could not be removed by forcibly pulling it up.
[0012]
If it is pulled up and removed by force, the lining-like clip attachment hole 5 or the clip 4 is often damaged. If the ridge-like clip attachment hole 5 or the clip 4 is damaged, It was also the cause of incomplete installation and abnormal noise due to vibration during driving.
[0013]
The shape and size of the clip varies depending on the type of vehicle, and there are many types of clips. Generally, a maintenance shop orders and obtains it as necessary without stocking it, and the clip is damaged. In addition to extending the repair period, the repair owner also imposed an extra financial burden on the owner of the car as the repair requester.
[0014]
Further, the groove 45 between the umbrella-shaped plate 41 and the plate A43 often has a substantially V-shaped cross section. As shown in FIG. 11, in the conventional product having a plate-shaped thin-walled section, the thin-walled section U-shaped groove. In many cases, however, the clip could not be sufficiently fitted, resulting in shallowness and damage to the clip.
[0015]
[Problems to be solved by the invention]
In view of the above problems, the present invention has an object to provide a clip removal tool that can also remove a clip attached around the center of the lining without damaging the clip attachment hole of the lining or the clip itself. Is.
[0016]
[Means for Solving the Problems]
The problems in the conventional products can be solved by the present invention as follows.
[0017]
That is, the first clip remover of the present invention is inserted into a bar-shaped clip extractor 2 having a U-shaped fitting groove 21 and a plate-like thin wall portion 22 provided at one end, and below the clip extractor 2. The push-up tool 3 having a substantially L-shaped or T-bar shaped arm portion 31 for pushing the plate-like thin portion 22 upward by sliding in the tip direction of the clip pull-out tool 2 is combined.
[0018]
In addition, the second clip remover according to the present invention is such that the rod-like extraction tool 2 of the first clip remover has a straight shape with no offset, and has an axial length of 350 mm so that it can also accommodate a clip at the center of the lining. That's it.
[0019]
Further, the third clip remover according to the present invention is provided with the concave portion 23 corresponding to the umbrella-like plate 41 on the umbrella-like plate fitting surface of the plate-like thin portion 22 of the first or second clip remover. Is.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0021]
FIG. 3 is a front view of the clip extractor 2 of the present invention, and FIG. 5 is a side view of a conventional clip extractor. A plate-like thin portion 22 is provided at one end of the shaft 23, and this thin portion is shown. 22 is provided with a U-shaped fitting groove 22 that is thin enough to engage with the groove 45 between the plate A 43 of the clip 4 and the umbrella-shaped plate 41.
[0022]
The shaft 23 may have a straight shape with no offset, but may be bent into a substantially square shape as in the conventional product, but a straight object is more effective especially when the work space is narrow. .
[0023]
The U-shaped fitting groove 21 is slightly U-shaped so as to correspond to the size of a larger number of clips.
[0024]
At the other end of the shaft 23, a handle 24 used as a driver handle is resin-molded to make it easier to hold and to apply force.
[0025]
The length X of the shaft portion is preferably 350 mm or more in consideration of the removal of the clip used around the center of the lining. However, even if it is 350 mm or less, the length X is the same depending on the position where the clip is attached. The clip can be removed using a push-up tool, and this is not an absolute requirement.
[0026]
FIG. 4 shows a push-up tool according to the present invention, in which an L-shaped or T-shaped arm portion is provided at one end of a round or square rod-shaped shaft 33, and the length Y of the shaft portion 33 is the same as that of the clip remover 2. It is preferably 350 mm or more, and a grip 34 for gripping is provided at one end.
[0027]
The shaft 33 of the push-up tool can be either a round cross-section bar or a square cross-section bar, but has a thickness of about 5 to 10 mm due to the lifting amount of the clip remover. It is preferable to provide the recess 35 so that the positional relationship is adjusted and the sliding operation and the lever operation can be performed smoothly.
[0028]
Further, by providing the concave plate 24 corresponding to the umbrella-shaped plate 41 on the umbrella-shaped plate fitting surface of the plate-shaped thin-walled portion 22, the clip 4 and the plate-shaped thin-walled portion 22 can be fitted deeply. Clip breakage can be prevented.
[0029]
In particular, if the thickness of the plate-like thin portion 22 can be reduced to about 1 mm, it is not necessary to use the umbrella-like or spherical recess 24 as shown in FIG. The thin-walled portion 22 is tapered gradually toward the taper shape, and there is a great effect in providing the concave portion 24 corresponding to the umbrella-shaped or spherical plate.
[0030]
Next, an actual removal procedure will be described with reference to the drawings.
[0031]
FIG. 11 is a view showing a state where the lining of the back gate 63 is attached. In order to remove the lining, the outer peripheral clip is first removed, but it may be removed by the lever principle as in the prior art.
[0032]
Next, in order to remove 62 clips around the center, after inserting and fitting the clip puller distal end thin portion 22 into the groove 45 between the plate A of the clip 4 and the umbrella-shaped plate 41, the clip puller 2 is attached to the shaft 23. If the arm portion 31 of the push-up tool 3 is inserted along and slid toward the tip of the clip pull-out tool 2, the plate-like thin portion 22 of the clip pull-out tool 2 pushes up as the arm portion 31 approaches the tip of the clip pull-out tool. The clip 4 can be pulled out from a clip mounting hole provided in the body panel.
[0033]
If there is a work space, the clip can be pulled out more easily by performing the lever operation using the arm portion 31 of the push-up tool 3 as a fulcrum.
[0034]
A comparison of the work space between the conventional product and the present invention will be described with reference to FIG.
[0035]
FIG. 8 shows the removal state of the present invention on the right side of the clip 4 by a solid line, and the removal state of the conventional product on the left side by an imaginary line.
[0036]
In the conventional product, the grip swing width Z at the time of lever operation is required, but if there is a space where the tool can be inserted, it can be removed, and the difference in W in the vertical direction compared to the conventional product Even a small space can be removed.
[0037]
【The invention's effect】
As described above, the first clip remover 1 of the present invention includes a bar-shaped clip puller 2 having a plate-shaped thin portion 22 having a U-shaped fitting groove 21 at one end, and a clip puller 2. Combined with the push-up tool 3 having a substantially L-shaped or T-shaped bar-shaped arm 31 for pushing the plate-like thin portion 22 upward by being inserted downward and sliding toward the tip of the clip pull-out tool 2 Enables removal even when the work space in the vertical direction is extremely small, such as a clip attached around the center of the lining, without damaging the clip attachment hole of the lining or the clip itself. This is a clip removing tool that can hold the clip reliably by providing a concave portion 24 corresponding to the umbrella-shaped plate on the umbrella-shaped plate fitting surface of the portion 22.
