Hereinafter, this embodiment will be described in detail using the drawings.
1 to 11 are for explaining this embodiment.

<Structure> The structure of this embodiment will be explained below.

As shown in FIG. 1 (FIG. 2), a masking tape 2 is attached to an object 1 to protect the portion of the object 1 to which the masking tape 2 is attached or its surroundings. At this time, the masking tape 2 is pasted using, for example, a masking tape pasting jig 3 as shown in Example 1 of FIGS. 3 (-6).

First, the object 1 will be explained. The object 1 may be any object to which the masking tape 2 is attached. In this embodiment, as shown in FIG. 1, the object 1 is an outer wall 11 of a building. Then, during renovation or after-sales maintenance of a building, the masking tape 2 is applied to the surface of the outer wall 11 or a narrow portion of the outer wall 11, for example, a recess 12 such as a joint formed in the outer wall 11. Hereinafter, a case where the masking tape 2 is attached to the bottom 12a of the recess 12 of the outer wall 11 will be described as a preferred example.

However, the object 1 is not limited to the outer wall 11 of a building, and the masking tape application jig 3 is used to apply masking tape 2 to the bottom 12a of the recess 12 (joint area) during building renovation or after-sales maintenance. It is not limited to uses.

Next, the masking tape 2 will be explained. The masking tape 2 is an adhesive tape that has relatively weak adhesive strength and can be easily applied or removed without leaving any traces on the object 1. The masking tape 2 is used, for example, during painting, sealing, caulking, etc., to protect the area around the work area and prevent it from getting dirty. Such work is performed for repairs and the like during building renovation and after-sales maintenance as described above. However, the masking tape 2 is widely used in areas other than buildings and in areas other than repaired parts of buildings.

The masking tape 2 has a tape base material 6 and an adhesive surface 7. The adhesive surface 7 is formed, for example, by applying a layer of adhesive to one side of the tape base material 6. The surface (back surface) of the masking tape 2 opposite to the adhesive surface 7 is a non-adhesive surface on which the tape base material 6 is directly exposed.

The masking tape 2 may be made of any material (tape base material 6 and adhesive) and adhesive performance as long as it is suitable for the purpose of use. The masking tape 2 may be wound into a roll. In the masking tape application jig 3, the masking tape 2 is mainly used in the form of a tape piece that is pulled out from a roll portion and cut into a required length at the pulled-out portion.

The masking tape application jig 3 is a jig for assisting the application of the masking tape 2 to the object 1. The masking tape application jig 3 of this embodiment is capable of, for example, applying the masking tape 2 to a narrow area of the object 1 in a short time, accurately and reliably. The masking tape application jig 3 of this embodiment can also be used to accurately apply masking tape to a wide portion of the surface of the object 1.

As described above, when attaching the masking tape 2 to the bottom 12a of the recess 12 (such as a joint) of the outer wall 11 as the object 1, the masking tape 2 is attached to the width W1 of the bottom 12a of the joint. Those with approximately the same width T are used. Note that the masking tape 2 may have a width T that is slightly narrower than the width W1 of the bottom portion 12a of the joint portion, or a masking tape that has a width T that is slightly wider than the width W1 of the bottom portion 12a of the joint portion.

The joint portion (recessed portion 12) is a long and narrow groove-shaped mating gap formed between the outer wall panels that constitute the outer wall 11. The joint portion has a substantially uniform width W1 and a substantially uniform depth G1 over the entire length. The joint portion is sealed with, for example, a gasket. The joint portion may be a vertically long vertical joint or a horizontally long horizontal joint. The joint portion in this embodiment is a vertically long vertical joint.

In addition, when the exterior wall panel is brick-like or tile-like, a second joint part (second recess 13) is further provided on the inside of the exterior wall panel so as to be recessed with respect to the surface of the exterior wall panel. multiple lines are formed in parallel. The second recess 13 forms the outline of the brick or tile, giving the outer wall panel a three-dimensional pattern. The second recess 13 extends along the surface of the outer wall panel in a direction (for example, a perpendicular direction) intersecting the above-described joint (recess 12). The second recess 13 in this embodiment is a horizontally long horizontal joint.

The width W2 of the second recess 13 may be larger, the same, or smaller than the width W1 of the recess 12. In this embodiment, the width W2 of the second recess 13 is equal to or smaller than the width W1 of the recess 12. Further, the depth of the second recess 13 may be greater than, the same as, or smaller than the depth G1 of the recess 12. In this embodiment, the second recess 13 has the same depth as the depth G1 of the recess 12.

Note that the recess 12 in a broad sense may include the second recess 13. In that case, the recessed part 12 shall be read as the second recessed part 13.

The width W1 of the recess 12 and the width W2 of the second recess 13 are often narrower than a human finger. In that case, it becomes difficult to insert a finger into the recess 12 and the second recess 13 to apply the masking tape 2. Therefore, in order to apply the masking tape 2 to the recess 12 and the second recess 13, it is necessary to use some kind of tool. In such a case, the masking tape application jig 3 of this embodiment is used.

In this embodiment, the masking tape application jig 3 may have the following configuration.

In the following description, three mutually orthogonal directions with respect to the masking tape application jig 3 are referred to as a front-rear direction X, a width direction Y, and a perpendicular direction Z.

The front-rear direction X is a direction perpendicular to the object 1 when the masking tape application jig 3 is directed toward the object 1 in a correct posture. Among these, the side closer to the object 1 is the front side or the front of the masking tape application jig 3, and the side far from the object 1 is the rear side or back of the masking tape application jig 3. The width direction Y is a direction in which the masking tape application jig 3 extends laterally along the object 1. The perpendicular direction Z is the thickness direction of the masking tape application jig 3.

Note that the three mutually orthogonal directions with respect to the outer wall 11 as the object 1 are the up-down direction, the width direction (or the wall width direction), and the inside-outside direction (or the wall thickness direction). When the masking tape application jig 3 is used, the front-rear direction X is directed toward the inside and outside of the outer wall 11. The masking tape application jig 3 is oriented with the width direction Y toward the extending direction of the recess 12 and the second recess 13 (vertical direction, wall width direction), etc. Further, the masking tape application jig 3 is oriented with the perpendicular direction Z toward the direction of the groove width of the recess 12 and the second recess 13 (wall width direction, vertical direction), etc.

(1) As shown in Figure 5 (Figure 6), the masking tape application jig 3 is
a jig main body 21 having a flat surface at least on the front portion 21a;
It has a mounting part 22 for the masking tape 2 installed on one side of the front part 21a of the jig main body 21.
The attachment part 22 has a pair of legs 23 installed on the front edge 21b of the front part 21a and spaced apart in the width direction Y, and is installed on both side edges 21c of the front part 21a, so that the pair of legs 23 are spaced apart from each other in the width direction Y. and a pair of arm portions 24 located on both sides in the width direction Y between the two.
The pair of leg portions 23 are located further forward than the pair of arm portions 24.

Here, the overall perspective view of FIG. 5 clearly shows the shape of the masking tape application jig 3. The three-view diagram of FIG. 6 shows the dimensional relationship of each part of the masking tape application jig 3. Hereinafter, FIGS. 5 and 6 will always be referred to.

The jig main body 21 is a part that becomes the main body of the masking tape application jig 3. The jig main body 21 is made of metal, resin, or the like. In this embodiment, the jig main body 21 is made of metal.

The front portion 21a is approximately half of the jig main body 21 in the front-rear direction X, which is the side closer to the object 1 when the masking tape application jig 3 is placed in the correct direction relative to the object 1. The front portion 21a is provided with the pair of legs 23 and the pair of arms 24 described above.

The front portion 21a of the jig main body 21 is directed toward the object 1 during use and is installed perpendicular to the object 1. The front portion 21a mainly has a flat surface extending in the width direction Y and the front-rear direction X. The front portion 21a has a horizontally long planar shape that extends long in the width direction Y and is short in the front-rear direction X. The front portion 21a may be substantially entirely flat. Further, the front portion 21a may locally have an uneven portion within the width W1 of the recess 12 (joint portion), for example. This allows the front portion 21a to be inserted into the recess 12. In this embodiment, the entire front portion 21a is a flat surface.

On the other hand, the remaining approximately half of the jig main body 21 in the front-rear direction X, which is the side far from the object 1, becomes the rear side portion 21d. A clear boundary (or boundary line) may or may not be provided between the front portion 21a and the rear portion 21d. In this example, no clear boundaries are provided.

The entire rear portion 21d of the jig body 21 serves as a grip portion for holding and operating the body portion by hand during use. Alternatively, the rear portion 21d has at least a portion that becomes a grip portion. The grip portion may have any shape or structure. For example, a string hole 25 for passing a string such as a strap may be provided in the rear portion 21d. Note that a more specific structure of the jig main body 21 will be described later.

One side of the front portion 21a is one side of the front portion 21a having a flat surface. One side may be either side. The pair of legs 23 and the pair of arms 24 are provided at least on the same side with respect to the flat surface of the front portion 21a of the jig main body 21.

The pair of legs 23 and the pair of arms 24 extend from the same surface, which is one side of the front portion 21a, in an out-of-plane direction or in a direction intersecting the jig main body 21. The out-of-plane direction or the direction intersecting the jig main body 21 may be a direction Z perpendicular to the plane of the front portion 21a, or a direction other than the direction Z perpendicular to the plane.

As a result, the pair of legs 23 and the pair of arms 24 become non-parallel to the flat surface of the front portion 21a. The pair of legs 23 and the pair of arms 24 may extend in substantially the same direction, or may extend in slightly different directions.

In this embodiment, the directions in which the pair of legs 23 and the pair of arms 24 extend are substantially parallel to each other in the same direction when viewed only from the center line without considering the orientation of the surfaces. In this embodiment, the direction in which the pair of legs 23 and the pair of arms 24 extend is a direction Z perpendicular to the front portion 21a.

For example, the masking tape 2 is attached to the attachment part 22 in the form of a piece of tape cut to match the length of the portion of the object 1 to which the masking tape 2 is attached. Note that the masking tape 2 may be cut into tape pieces before being attached to the attachment portion 22, or may be cut into tape pieces after being attached.

The mounting portion 22 is a portion of the jig main body 21 to which the masking tape 2 is mounted. The attachment part 22 is capable of stably holding the tape piece of the masking tape 2 on the jig main body 21 until the masking tape 2 is applied to the object 1.

The front edge portion 21b is an edge of the front portion 21a of the jig main body 21 that faces the object 1 side. The front edge portion 21b is a side that is located on the front side (front side) of the jig main body 21 in the front-rear direction X and extends linearly in the width direction Y.

The foot portion 23 is a foot-shaped protruding portion provided on the masking tape application jig 3 as a part of the mounting portion 22 . The pair of feet 23 is installed in the front-rear direction X at approximately the same position as the front edge 21b or on the front side of the front edge 21b. In this embodiment, the positional relationship of each leg 23 with respect to the front-rear direction X of the jig main body 21 is approximately the same.

The pair of foot portions 23 are provided at both ends of the front edge portion 21b in the width direction Y with a distance D1 between them. The distance D1 between the pair of legs 23 is set narrower than the length of the tape piece described above. For example, the interval D1 is set to be approximately the same length as the portion of the object 1 to which the masking tape 2 is attached. The distance D1 between the pair of leg portions 23 may be defined between the inner sides or between the outer sides.

The side edge 21c is an edge located on the side of the front edge 21b in (the front portion 21a of) the jig main body 21. The side edge portions 21c are sides that are located on both sides of the jig main body 21 in the width direction Y and extend in the front-rear direction X.

The arm portion 24 is an arm-shaped protruding portion provided on the masking tape application jig 3 as a part of the mounting portion 22, separately from the foot portion 23. The pair of arm portions 24 are installed on the rear side of the front edge portion 21b with respect to the front-rear direction X. In this embodiment, the positional relationship of each arm portion 24 with respect to the front-rear direction X of the jig main body 21 is approximately the same.

The pair of arm portions 24 are provided at respective positions on both side edge portions 21c with a distance D2 between them. As a result, the pair of arm portions 24 are spaced wider in the width direction Y than the pair of foot portions 23 (D2>D1), and are positioned on the rear side of the pair of foot portions 23 in the front-rear direction X. The distance D2 between the pair of arm portions 24 may be defined between the inner sides or between the outer sides.

The term "both sides with the pair of legs 23 in between" means that each of the pair of arms 24 is located on the outer side of the jig body 21 in the width direction Y than each of the pair of legs 23. be. The pair of arm portions 24 are located on one side of the jig body 21 along with the pair of legs 23 in the width direction of the jig body 21 when the jig body 21 is viewed in the front-rear direction X from the rear side to the front side. They are installed so as to be lined up almost in a straight line along Y.

The front side is the side closest to the object 1 in the front portion 21a of the jig main body 21. By being located at the frontmost side (or protruding forward), the pair of legs 23 is brought into almost direct contact with the object 1 via the tape piece.

The masking tape 2 is attached to such a masking tape application jig 3 as follows (FIGS. 3 and 4).

The intermediate portion 2a of the masking tape 2 is supported from the back side by a pair of legs 23. At this time, the masking tape 2 is not attached to the foot portion 23. Therefore, the foot portion 23 serves as a support portion for the back surface of the masking tape 2.

Further, the masking tape 2 is attached to the pair of arm portions 24 at both end portions 2b. At this time, the areas around both ends 2b of the masking tape 2 are set against the mutually opposing surfaces of each arm portion 24 (the surface on the leg portion 23 side or the inner surface in the width direction Y of the jig main body 21). An adhesive surface 7 is attached. The arm portions 24 serve as attachment portions to the adhesive surface 7 of the masking tape 2.

Further, the leg portion 23 serves as a bending starting point portion that bends the peripheral portions 2b of both ends of the masking tape 2 relative to the intermediate portion 2a toward the arm portion 24.

Therefore, in the adhesive surface 7 of the masking tape 2, the middle part 2a faces the front side, the periphery 2b of both ends is bent by the foot part 23, and the bent periphery 2b of both ends is on the outside in the width direction Y (not the foot part 23). It is attached to the attachment part 22 in a state facing toward the opposite side).

The intermediate portion 2a of the masking tape 2 may be supported in a taut state with respect to the pair of legs 23. However, some slack in the middle portion 2a of the masking tape 2 is allowed. The tension of the masking tape 2 with respect to the intermediate portion 2a is adjusted depending on the position at which both end portions 2b of the masking tape 2 are attached to the arm portion 24.

At this time, both ends or at least one end of the masking tape 2 may be cut into a longer length so as to protrude from the arm part 24. Then, by folding the tape in half and pasting the adhesive surfaces 7 together, the protruding portion becomes an operating end of the masking tape 2 that will not stick to the surroundings. By grasping and pulling this operating end, the tension of the masking tape 2 can be easily adjusted.

In the masking tape application jig 3 to which the masking tape 2 is attached, when the masking tape 2 is applied to the object 1, the pair of legs 23 supporting the back surface of the intermediate portion 2a press against the surface of the object 1. applied to the surface of the object 1 (when pasted on the surface of the object 1). Alternatively, the pair of legs 23 are inserted into the recess 12 (joint part) formed in the object 1 and pressed against the bottom 12a of the joint (in the case of pasting on the bottom 12a of the recess 12). Thereby, the intermediate portion 2a of the masking tape 2 is attached to the surface of the object 1 or the bottom portion 12a of the joint.

(2) In masking tape application jig 3,
The pair of legs 23 may be shorter than the pair of arms 24 in the direction Z perpendicular to the plane of the jig main body 21.

Here, the pair of legs 23 extends by a required length in the substantially perpendicular direction Z of the jig main body 21 (leg length L1). Further, the pair of arm portions 24 extend by a required length in the substantially perpendicular direction Z of the jig main body 21 (arm length L2).

And, being short with respect to the perpendicular direction Z of the jig main body 21 means that the leg length L1 of the pair of legs 23 is shorter than the arm length L2 of the pair of arms 24 (L1<L2 ). Alternatively, the arm length L2 of the pair of arm portions 24 is longer than the leg length L1 of the pair of leg portions 23 (L2>L1).

For example, the arm length L2 of the arm portion 24 is approximately 1.5 to 2.5 times the leg length L1 of the leg portion 23.

Note that the pair of legs 23 may have the same leg length L1 in the direction Z perpendicular to the plane. Furthermore, the pair of legs 23 may have slightly different leg lengths L1 from each other. In this embodiment, the pair of legs 23 have the same leg length L1 in the direction Z perpendicular to the plane.

The pair of arm portions 24 may be aligned to have the same arm length L2 in the perpendicular direction Z. Furthermore, the arm lengths L2 of the pair of arm portions 24 may be slightly different from each other. In this embodiment, the pair of arm portions 24 have the same arm length L2 in the direction Z perpendicular to the surface.

Structurally, the leg length L1 of the pair of legs 23 can be the same as the arm length L2 of the pair of arms 24, but it is possible to make them different as in this embodiment. Also good.

For example, when the width T of the masking tape 2 is used as a reference, the masking tape application jig 3 may have the leg length L1 of the pair of legs 23 shorter than the width T of the masking tape 2. In the masking tape application jig 3, the arm length L2 of the pair of arm portions 24 may be approximately the same as the width T of the masking tape 2, or may be slightly longer or shorter than that.

For example, the foot length L1 of the foot portion 23 may be approximately 1/2 or more or less (for example, 0.4 to 0.7 times) of the width T of the masking tape 2. Further, the arm length L2 of the arm portion 24 may be approximately the same as the width T of the masking tape 2 (for example, 0.8 times to 1.0 times).

Further, when the width W1 of the joint portion is used as a reference, the masking tape application jig 3 may have a leg length L1 of the pair of legs 23 shorter than the width W1 of the joint portion. In the masking tape application jig 3, the arm length L2 of the pair of arm portions 24 may be approximately the same as, or slightly longer or shorter than, the width W1 of the joint portion.

For example, the foot length L1 of the foot portion 23 may be approximately 1/2 or more or less (for example, 0.4 to 0.7 times) of the width W1 of the joint portion. Further, the arm length L2 of the arm portion 24 may be approximately the same as the width W1 of the joint portion (for example, 0.8 times to 1.0 times).

(3) In masking tape application jig 3,
The pair of legs 23 may have a narrower width than the pair of arms 24.

Here, the pair of foot portions 23 have a required width (foot width S1). Further, the pair of arm portions 24 have a required width (arm width S2). The foot width S1 and arm width S2 are the widths described above.

The foot width S1 of the foot portion 23 is the width of the surface along the extending direction of the masking tape 2. The foot width S1 of the foot portion 23 is approximately the dimension in the width direction Y of the front portion 21a of the jig main body 21 by following the intermediate portion 2a of the masking tape 2.

The foot width S1 of the foot portion 23 is, for example, a dimension having a strength greater than or equal to the minimum strength capable of supporting the back surface of the intermediate portion 2a of the masking tape 2. For example, the foot width S1 of the foot portion 23 may be approximately three to five times the thickness of the jig main body 21. Note that the foot width S1 of the foot portion 23 may be set based on factors other than those mentioned above.

The arm width S2 of the arm portion 24 is the width of the surface along the extending direction of the masking tape 2. Note that the direction in which the masking tape 2 extends is changed by bending the peripheries 2b of both ends of the masking tape 2. The arm width S2 of the arm portion 24 is approximately the dimension of the jig main body 21 in the front-rear direction X by approximately following the peripheries 2b of both ends of the masking tape 2.

The arm width S2 of the arm portion 24 is, for example, a dimension that has an area greater than or equal to the minimum area to which the both end peripheries 2b of the masking tape 2 can be reliably attached. The arm width S2 is set by the adhesive force of the adhesive surface 7 of the masking tape 2, etc.

The foot portion 23 being narrower than the arm portion 24 means that the foot width S1 of the foot portion 23 is smaller than the arm width S2 of the arm portion 24 (S1<S2). Alternatively, the arm width S2 of the arm portion 24 is larger than the foot width S1 of the foot portion 23 (S2>S1). For example, the arm width S2 of the arm portion 24 may be approximately 2 to 3.5 times the foot width S1 of the foot portion 23.

Note that the pair of foot portions 23 may have the same foot width S1. Alternatively, the pair of foot portions 23 may have slightly different foot widths S1 from each other. In this embodiment, the pair of foot portions 23 have the same foot width S1.

The pair of arm portions 24 may be arranged to have the same arm width S2. Alternatively, the pair of arm portions 24 may have arm widths S2 that are slightly different from each other. In this embodiment, the pair of arm portions 24 have the same arm width S2.

Note that, structurally, the leg width S1 of the pair of foot sections 23 can be made the same as the arm width S2 of the pair of arm sections 24, but it is also possible to make them different as in this embodiment. .

(4) In masking tape application jig 3,
The distance between the leg portion 23 and the arm portion 24 may be greater than the thickness of the object 1 to which the masking tape 2 is attached or the depth G1 of the recess 12 provided in the object 1.

Here, the distance between the leg portion 23 and the arm portion 24 refers to the separation distance G2 between the leg portion 23 and the arm portion 24 in the front-rear direction X of the jig main body 21. That is, it refers to the separation distance G2 between each leg 23 and the arm 24 on the same side as the leg 23.

The object 1 is the object to which the masking tape 2 is applied, and may be any object, but in this embodiment, it is the outer wall 11 as described above.

The thickness of the object 1 is, for example, the thickness of an outer wall panel, and is the dimension from the back surface to the front surface of the object 1.

The term "separation greater than the thickness of the object 1" means that the separation distance G2 between the leg section 23 and the arm section 24 in the front-rear direction X is greater than the thickness of the object 1.

The foot portion 23 is based on the position of the frontmost portion of the foot portion 23. The arm portion 24 is based on the position of the most anterior portion of the arm portion 24 .

The recess 12 may be of any type, but in this embodiment, it is a joint in the outer wall 11, as described above. The recess 12 may include a second joint (second recess 13).

The depth G1 of the recess 12 is the depth dimension (dimension in the inside and outside direction) of the joint part perpendicular to the object 1. The depth G1 of the recess 12 is substantially constant.

Being far apart from the depth G1 of the recess 12 means that the separation distance G2 between the foot 23 and the arm 24 in the front-rear direction X is greater than the depth G1 of the recess 12 (G2> G1).

The legs 23 may be provided at the same position with respect to the front-rear direction X. Furthermore, the positions of the legs 23 may be slightly different from each other. In this embodiment, the legs 23 are at the same position.

The arms 24 may be provided at the same position with respect to the front-rear direction X. Moreover, the positions of the arm portions 24 may be slightly different from each other. In this embodiment, the arms 24 are at the same position.

Further, the distance G2 between the leg portion 23 and the arm portion 24 may be the same on both sides in the width direction Y. Further, the distance G2 between the leg portion 23 and the arm portion 24 may be slightly different on both sides in the width direction Y. In this embodiment, the separation distance G2 is the same on both sides.

Note that, structurally, it is possible to make the separation distance G2 the same as or smaller than the depth G1, but it is also possible to make it different as in this embodiment.

(5) In masking tape application jig 3,
The foot portion 23 may be formed into an extension portion 31 that extends from the front portion 21a of the jig main body 21 to the front side longer than the thickness of the object 1 or the depth G1 of the recess 12.

Here, the extension part 31 is a part that continuously extends in a long and narrow direction from the front edge part 21b of the front part 21a of the jig main body 21 in the front-rear direction X with respect to the front side of the jig main body 21. The extension portion 31 is provided individually for each foot portion 23. The extension portion 31 is interposed between the jig main body 21 and each leg portion 23. Alternatively, each leg portion 23 is formed at the tip of each extension portion 31 extending from the jig main body 21 to the front side.

Each extension portion 31 is formed to have a substantially uniform width (=S1) that is substantially equal to the foot width S1 of each foot portion 23. The extension part 31 is longer than the depth G1 of the recessed part 12 and is formed substantially linearly in the front-rear direction X (extension part 31>depth G1). The pair of extensions 31 are formed substantially parallel.

However, structurally, each extension part 31 can have a width different from the foot width S1 of each foot part 23, or can have a width that is not uniform. For example, the strength of each extension part 31 can be increased by increasing the width of each extension part 31 from the foot part 23 toward the front part 21a.

Further, as shown in Example 2 of FIG. 7, the masking tape application jig 3 has a structure in which no extension part 31 is provided between the front part 21a of the jig main body 21 and the pair of legs 23. is also possible. In the second embodiment, the foot portion 23 is formed directly on the front edge portion 21b of the front portion 21a of the jig main body 21. The second embodiment is formed to have the same dimensional relationship as the first embodiment as a whole, except that the front portion 21a is also extended by the extension portion 31, thereby eliminating the extension portion 31. Contrary to the above, when the second embodiment is used as a reference, the extension part 31 of the first embodiment is cut out between the pair of legs 23 of the front part 21a of the jig main body 21 of the second embodiment. will be formed. For example, when applying the masking tape 2 to the bottom 12a of the recess 12, if the extension 31 is not provided, at least a portion of the front portion 21a will be inserted into the recess 12, but by providing the extension 31, the front portion 21a will be inserted into the recess 12. There is no need to insert it into the recess 12.

A more specific structure of the masking tape application jig 3 of this embodiment will be described below.

In the masking tape application jig 3 of this embodiment, a jig main body 21, a pair of legs 23, and a pair of arms 24 are integrally formed by bending a single flat metal plate. has been done. Such a masking tape application jig 3 can be manufactured by one press process. As a result, the masking tape application jig 3 is inexpensive, easy to manufacture, small and lightweight, easy to carry, and easy to handle and work with.

In this case, at least the front portion 21a of the jig main body 21 has a horizontally elongated substantially rectangular shape extending in the width direction Y. The front edge portion 21b of the horizontally long front portion 21a has a width approximately equal to the sum of the distance D1 between the pair of foot portions 23 and the foot width S1 of the pair of foot portions 23.

The pair of legs 23 is formed by bending all or part of a pair of substantially parallel first projecting pieces 32. The first protruding pieces 32 are integrally formed at both ends of the front edge 21b of the horizontally long front portion 21a in the width direction Y so as to protrude toward the front side in the front-rear direction X. The first projecting piece 32 is bent substantially perpendicularly toward one side of the front portion 21a. The first protruding piece 32 has a substantially uniform width (=S1) over its entire length. In this case, the width of the first protruding piece 32 is preferably narrower than the width W1 of the recess 12 and the width W2 of the second recess 13.

When the entire first protruding piece 32 is bent, the state of Embodiment 2 with only the foot part 23 and no extension part 31 is obtained, and when a part of the first protruding piece 32 is bent, the extension part 31 and the foot portion 23 of the first embodiment. The foot portion 23 is bent along the width direction Y so as to form a surface that is perpendicular to the jig body 21 and extends in the width direction Y of the jig body 21.

The pair of arm portions 24 are formed by bending all or part of the pair of second protruding pieces 33 substantially perpendicularly to one surface of the front portion 21a. The second projecting pieces 33 are integrally formed with both side edges 21c of the horizontally long front portion 21a so as to project outward in the width direction Y. The second projecting piece 33 has a substantially uniform width (=S2) over its entire length.

The second protruding piece 33 is approximately 2 to 3.5 times as wide as the first protruding piece 32. When the entire second projecting piece 33 is bent, the second projecting piece 33 is the only one without the horizontal projecting part 34, and when only a part is bent, the horizontal projecting part 34 and the arm part 24 are bent. It will have the following. The arm portion 24 of the second protruding piece 33 is bent so that the surface direction thereof is different from that of the leg portion 23 of the first protruding piece 32. The arm portion 24 is bent along the front-rear direction X so as to be perpendicular to the jig main body 21 and the leg portion 23 .

The horizontal projecting portion 34 does not need to be provided, but if the horizontal projecting portion 34 is provided as in the first and second embodiments, both ends of the masking tape 2 bent at the foot portion 23 and directed toward the arm portion 24 The bending angle of the periphery 2b can be set by the length of the horizontal protrusion 34.

Without the horizontal protrusion 34, the bending angle is approximately 90 degrees, but with the horizontal protrusion 34, the bending angle can be made larger than 90 degrees. Thereby, the arm portion 24 is arranged so that the masking tape 2 can be easily attached to it and easily peeled off. The length G3 of the horizontal projecting portion 34 in the projecting direction (width direction Y) may be, for example, approximately 1/3 to 2/3 of the arm width S2 of the arm portion 24.

The front portion 21a is a flat surface that faces in a direction perpendicular to the object 1 (internal and external directions), but as for the rear portion 21d, it is sufficient that at least a part thereof can be used as a gripping portion. It does not have to be perpendicular to the surface. For example, with respect to the front part 21a, the rear part 21d may be bent out of the plane of the front part 21a at a boundary line extending in the width direction Y or at a position on the rear side of the boundary line, so as to be shaped to be easy to hold. It's okay. In this embodiment, the rear portion 21d remains a surface perpendicular to the object 1 (a surface flush with the front portion 21a).

Further, the rear portion 21d may be provided with a finger hole or the like as appropriate, as long as it is easy to hold and handle as a gripping portion. Further, an anti-slip member such as a sheet or tape or a cushioning material may be attached as appropriate.

Note that the masking tape application jig 3 is not limited to one formed of a single metal plate, and may have a configuration other than that formed of a single metal plate. For example, the legs 23 and arms 24, which are formed as separate parts, may be attached to and integrated with the flat jig main body 21, respectively. Further, for example, the leg portion 23 and the arm portion 24 are not limited to a flat plate shape, and may be, for example, rod-shaped (square rod or round rod) or curved (cylindrical).

Note that each of the configurations described above can be used in appropriate combinations.

<Function> The function of this embodiment will be explained below.

First, the masking tape 2 is cut to a required length according to the length of the part to be pasted.

First, the tape piece of the masking tape 2 cut to a required length is pasted with the adhesive surface 7 around one end portion 2b to one inner surface (opposing surface) of the arm portion 24 in the mounting portion 22.

Next, the intermediate portion 2a of the masking tape 2 is routed between the pair of legs 23 in order, and the back surface of the masking tape 2 is supported by the pair of legs 23. Furthermore, the other end periphery 2b of the masking tape 2 is guided to the other arm 24, and the adhesive surface 7 of the other end periphery 2b is pasted on the inner surface of the other arm 24. Thereby, the masking tape 2 is set in the mounting part 22, and the adhesive surface 7 of the intermediate part 2a between the pair of legs 23 is directed to the front side. In addition, the masking tape 2 may be set in the attachment part 22 in an uncut state, and after being affixed to the other arm part 24, the portion after the affixation may be cut.

The middle portion 2a of the masking tape 2 is supported from the back side by the pair of legs 23 located on the front side, and is brought to the front. Then, the masking tape 2 is bent rearward by the pair of legs 23 at both end portions, and moves toward the pair of arm portions 24 located on the rear side of the pair of legs 23 . It is pasted and set on the inside of each. As a result, the masking tape 2 is stably attached to the jig main body 21 of the tape application auxiliary jig in a substantially C-shape when viewed from the front.

Once the masking tape 2 is attached to the jig main body 21 in this manner, the jig main body 21 holds the foot portion 23 perpendicular to the outer wall panel with the foot portion 23 facing the object 1, for example, the outer wall panel. Furthermore, the jig body 21 is held so as to extend along the joints (recesses 12) of the outer wall panel. In this state, the jig main body 21 inserts the pair of legs 23 on the front side into the joint part almost perpendicularly (FIG. 1).

As a result, the middle part 2a of the masking tape 2, which is supported from the back side by the pair of legs 23, is inserted deep into the joint, and is pressed against the joint by the feet 23, so that the bottom of the joint 12a.

At this time, the middle portion 2a of the masking tape 2 between the pair of legs 23 may be more firmly attached using a stick such as a spatula 41 (FIG. 8), if necessary.

Thereafter, the ends of the masking tape 2 are peeled off from the inner surfaces of the pair of arm parts 24, and the masking tape 2 is separated from the jig main body 21. At this time, the pair of legs 23 are located on the front side of the jig main body 21, and the pair of arms 24 are located on the rear side of the pair of legs 23. Therefore, part or all of the pair of arm portions 24 protrude outside the joint portion.

Therefore, even when the foot 23 is inserted into the joint, at least a portion of the arm 24 is outside the joint, so the masking tape can be applied from the inner surface of the arm 24 outside the joint. 2 can be easily peeled off.

When the masking tape 2 is peeled off, the jig main body 21 is moved to the rear side in the front-rear direction X and pulled out from the joint, thereby taking out the entire jig main body 21 out of the joint.

As a result, the jig main body 21 is separated from the masking tape 2 and taken out of the joint, and the masking tape 2 is left in the joint with the masking tape 2 attached to the joint (FIG. 2).

The peripheries 2b of both ends of the masking tape 2 may be left as they are floating above the joint, or all or part of them may be affixed to the joint using a spatula 41 or the like.

Note that the masking tape 2 may form an operating end around at least one end portion 2b by folding it in half and pasting the adhesive surfaces 7 together. As described above, the masking tape 2 can be easily and accurately attached to the joint portion.

Thereafter, repairs are made to the joints and the periphery of the joints, and after the repair, the masking tape 2 is peeled off from the joints. Thereby, repair can be performed without staining the object 1.

Note that the same applies to the case where the masking tape 2 is applied to the surface of the outer wall panel.

<Effects> According to this embodiment, the following effects can be obtained.

(Effect 1) The masking tape application jig 3 includes a jig body 21 having at least a flat front portion 21a, and a mounting portion 22 for the masking tape 2 installed on one side of the front portion 21a of the jig body 21. Equipped with The mounting part 22 includes a pair of feet 23 installed on a front edge 21b of the front part 21a and spaced apart in the width direction Y, and a pair of feet 23 installed on both side edges 21c of the front part 21a. and a pair of arm portions 24 located on both sides with the . The pair of legs 23 may be located in front of the pair of arms 24.

Therefore, the masking tape application jig 3 supports the back surface of the intermediate portion 2a of the masking tape 2 in the width direction Y by the pair of legs 23 extending toward one side of the jig main body 21. In this state, both end portions 2b of the masking tape 2 are attached to the pair of arm portions 24 of the jig main body 21. Thereby, the mounting part 22 can mount the masking tape 2.

At this time, the masking tape 2 is bent by the pair of legs 23 on the front side, and the peripheries 2b of both ends are directed from the front side toward the pair of arms 24 on the rear side.

Thereby, the masking tape 2 can be easily attached to the jig main body 21 and stably held by the jig main body 21. At this time, if the pair of legs 23 and the pair of arms 24 extend parallel to each other on the same side of the jig main body 21, the masking tape 2 can be attached to the mounting part 22 without twisting. Since it can be mounted, mounting on the jig main body 21 becomes easier.

Then, the masking tape application jig 3 presses a pair of legs 23 located on the front side of the jig main body 21 against the object 1. Thereby, the intermediate portion 2a of the masking tape 2 supported by the pair of legs 23 can be attached to the object 1.

At this time, since the jig main body 21 has the flat front part 21a, it is possible to aim at the object 1 based on the flat front part 21a and paste the masking tape 2 onto the object 1 accurately. can.

Thereafter, the masking tape application jig 3 peels off the masking tape 2 from the pair of arms 24 on the rear side, and moves the jig main body 21 away from the object 1. Thereby, the jig main body 21 can be separated from the masking tape 2 and the object 1 while leaving the masking tape 2 on the object 1.

Since the arm portion 24 is located on the rear side of the jig main body 21 than the pair of legs 23 on the front side, the periphery 2b of both ends of the masking tape 2 is removed from the arm portion 24 at a position away from the object 1. Can be easily peeled off.

As described above, the masking tape application jig 3 can easily and accurately apply the masking tape 2 even to a narrow part of the object 1 (for example, the recess 12 provided in the object 1). .

The masking tape application jig 3 is convenient because it can be used to accurately apply the masking tape to the surface of the object 1 if necessary.

(Effect 2) In the masking tape application jig 3, the pair of legs 23 may be shorter than the pair of arms 24 in the direction Z perpendicular to the plane of the jig main body 21.

In this way, by making the pair of legs 23 relatively shorter than the arms 24 in the perpendicular direction Z, the back side of the masking tape 2 is made wider than the width T of the masking tape 2 by the pair of short legs 23. can also be supported within a narrow range. As a result, the pair of feet 23 can be inserted into a part of the object 1 (for example, the recess 12) where the width W1 is the same as or slightly wider than the masking tape 2 (for example, the recess 12), and the masking tape 2 can be inserted. It becomes possible to paste.

At this time, the portion of the masking tape 2 that is not supported by the pair of legs 23 is easily deformed, so that it can be easily inserted into the narrow portion of the width W1. Therefore, the pair of foot parts 23 can apply the masking tape 2 to the narrow part of the object 1 with the width W1 while maintaining the state in which the back surface of the intermediate part 2a of the masking tape 2 is supported by the foot parts 23. become.

Furthermore, by making the pair of arms 24 relatively longer than the legs 23 in the perpendicular direction Z, the width of the adhesive surface 7 attached to the pair of arms 24 of the masking tape 2 becomes wider. Therefore, the mounting portion 22 can stably hold the peripheries 2b of both ends of the masking tape 2 more widely by the pair of arm portions 24. For example, the pair of arm portions 24 may be long enough to cover almost the entire width T of the masking tape 2.

(Effect 3) In the masking tape application jig 3, the width of the pair of legs 23 may be narrower than that of the pair of arms 24.

In this way, by making the pair of legs 23 relatively narrower than the pair of arms 24, the legs 23 become thinner, and the position of the legs 23 becomes clearer. Therefore, the attachment part 22 can easily apply the masking tape 2 to the object 1 more accurately (in the width direction Y) while keeping the back side of the masking tape 2 supported by the pair of legs 23. Become.

Further, by making the pair of arm portions 24 relatively wider than the pair of foot portions 23, the masking tape 2 can be attached to the pair of arm portions 24 over a relatively long range of the adhesive surface 7. Therefore, the mounting portion 22 can hold the peripheries 2b of both ends of the masking tape 2 more strongly and stably with the pair of arm portions 24.

(Effect 4) In the masking tape application jig 3, the distance between the legs 23 and the arms 24 corresponds to the thickness of the object 1 to which the masking tape 2 is applied or the depth of the recess 12 provided in the object 1. The distance may be greater than G1.

As a result, the foot section 23 can easily reach the back side of the object 1 or the depth of the recess 12 (bottom section 12a) of the object 1, and even in that state, the arm section 24 can reach the back side of the object 1. It comes to the surface completely. Therefore, the intermediate portion 2a of the masking tape 2 can be reliably attached to the inner part of the recess 12. Moreover, even if the leg part 23 is inserted deep into the recess 12, the periphery 2b of both ends of the masking tape 2 can be easily peeled off from the arm part 24 at the surface of the object 1. Furthermore, if necessary, it is also possible to make the length of the arm 24 exposed on the surface of the object 1 (arm length L2) longer than the width W1 of the recess 12 or the width T of the tape.

(Effect 5) The foot portion 23 may be formed into an extension portion 31 that extends from the front portion 21a of the jig main body 21 to the front side longer than the thickness of the object 1 or the depth G1 of the recess 12.

As a result, even when the foot portion 23 is inserted deep into the recess 12 so as to reach the bottom 12a of the recess 12, the jig main body 21 is separated from the foot portion 23 by the extension portion 31 and the object 1 is The entire front portion 21a comes to be exposed on the surface of. Therefore, the front portion 21a of the jig main body 21 does not interfere with the object 1. Therefore, it becomes possible to move the jig main body 21, for example, in a direction intersecting the recess 12.

This becomes effective, for example, when the object 1 is provided with the second recess 13 that intersects with the recess 12.

That is, for example, as shown in FIGS. 9 to 11 in order, the masking tape 2 is pasted on the surface of the extension part 31 opposite to the protruding side of the foot part 23 so as to span between the extension parts 31. , and attached to the jig main body 21 (FIG. 9). At this time, the width T of the masking tape 2 is oriented in the front-back direction X (the inside-outside direction of the outer wall 11). Next, the extension 31 is inserted into the recess 12 of the object 1 (FIG. 10). Then, the jig main body 21 is moved laterally along the second recess 13 (FIG. 11). This makes it possible to attach the masking tape 2 to the side surface of the recess 12 and to peel it off from the extension 31 using the side surface of the recess 12 . In this case, the width of the extension portion 31 and the foot width S1 of the foot portion 23 are approximately the same as or smaller than the width W2 of the second recess 13. Note that the amount of lateral movement of the jig main body 21 may be small enough to peel off the masking tape 2 from the extension portion 31.
