Description

The present invention is a system kitchen, system bath installed in a kitchen, bathroom, washroom, etc. in a building,
The present invention relates to a caulking spatula for pressing a caulking material filled in a place where a vanity or the like and a building member constituting the building are in contact, or a plurality of building members constituting the building, for example, joints of a plurality of kitchen panels. Is.

The caulking process is performed in order to increase the watertightness and waterproofness by filling caulking materials between the gaps that occur when the system kitchen, wash basin, etc. are in contact with the building materials, or at the joints of multiple building materials, or the cupboards and furniture are building materials. This is done to fill the caulking material in the gap between the surfaces in contact with the surface and enhance the beauty.

For this reason, in the caulking process, a cartridge filled with a caulking material is loaded into a special caulking gun, the caulking material is pushed out, and the gaps and seams are filled.

Conventionally, a caulking spatula 100, 200 or 300 as shown in FIG. 3 is used to remove bubbles and voids in the caulking material after filling, and to clean the surface of the caulking material.
The pressing process is performed using.

These caulking spats are made of stainless steel caulking spatula body 101, 201 or 30.
1 and a gripping portion 102, 202 or 302 made of wood or synthetic resin attached to the other end. As for its usage, the operator can use caulking spatula 100, 200 or 300
The gripping part 102, 202 or 302 is held by hand, the spatula 103, 203 or 303 is pressed against the surface of the filled caulking material, and the filled caulking material is moved in a predetermined direction while being pressed. It is done by doing so.

In addition, when caulking material is filled in a deep part of a building structure such as a sash sill, one end of a spatula body 2 as shown in FIG. 4 is used to prevent an unnatural way of holding. Is formed in a narrow spatula 2c in which the angle α at which the spatula tip 2b intersects with the extension line 5a of one side edge of the curved line is approximately 45 ° or less. Caulking spatula to do
Has been proposed (Patent Document 1).

When the caulking spatula 1 bent into the proposed saddle shape is used, the caulking material can be pressed by an unreasonable holding method even for the caulking material filled in the deep portion of the sash sill. This is shown in FIG.
JP 7-305492 A

When caulking material is filled in wide, narrow, or narrow places, according to the prior art, prepare multiple caulking spats suitable for the width and location according to the situation. It was necessary to use properly.
If a caulking spatula that does not fit the width or location is used, the caulking material will be scraped off more than necessary, or if it is held at an unreasonable angle, reliable pressing cannot be performed, so bubbles and voids cannot be completely removed. There arises a problem that the surface finish is not smooth.
A spatula for curved caulking caulking 1 proposed to avoid holding at an unreasonable angle.
However, pressing the caulking material filled in the narrow corner as shown in FIG. 6 inevitably becomes a difficult task.

The present invention has been made in view of the above circumstances, and without caulking a plurality of caulking spats to prepare a caulking process for a wide part, a narrow part, a narrowly complicated part, etc.
The present invention relates to a caulking spatula that can be pressed with a caulking spatula of a book to reliably remove bubbles and voids, and to finish the surface finish beautifully.

In order to solve the above problems, in the present invention, four spatula tips that are orthogonal to each other are arranged at one end of a spatula body made of a thin metal plate, and are orthogonal to the longitudinal center of gravity line of the spatula body. In order to make the crossing angle with the four spatula tips to be inclined approximately 40 to 50 degrees, respectively, and to smoothly connect the two spatula tips and the spatula body among the four spatula tips forming the rectangular shape, One side edge of both sides of the spatula body is connected to one spatula tip from a linear shape to an arc shape, and the other side edge is connected to another spatula tip from an arcuate shape to a reverse arc shape. The caulking spatula is configured so as to have a gripping member at the other end.

In the conventional method, it was necessary to prepare separate caulking spats for wide and narrow portions, but in the caulking spatula of the present invention, a plurality of rectangular shapes are formed at the tip of the spatula body. Since the spatula tips corresponding to the long side and the short side of the rectangle have different widths, it is possible to deal with objects having different widths with one spatula.

In addition, when pressing the caulking material at the complicated place, there is a case where the caulking process can be easily performed by using the proposed spatula 1 for curved corrugated caulking, which is easy to hold (FIG. 5). ). However, pressing the caulking material filled in the narrow corner as shown in FIG. 6 is inevitably a very difficult task.

In this regard, the caulking spatula of the present invention has four rectangular spatula tips, and the orientation of the two spatula tips forming two opposing long sides or two short sides is exactly 180.
° Since the direction is reversed, the operator has more flexibility in how to hold the spatula, and can always select an unreasonable way to hold.

That is, when the caulking spatula of the present invention is used differently from the bowl-shaped curved caulking spatula 1, it can be held in a comfortable manner in either case of FIG. 5 or FIG. effective.

Also, as shown in FIG. 7, when performing the caulking process at the corner of the protruding corner, when using a conventional caulking spatula, the spatula tips 103, 203 or 2b, 2d of many spats are also linear. The finished surface at the corners had to be flat. When the caulking spatula of the present invention is used, as shown in FIG. 8, the arcuate portion 1050 or 1060 is pressed against the surface of the caulking material and moved in a predetermined direction, so that it is easy to finish the rounded corner caulking. There is an effect that can be done.

It is a top view of the caulking spatula of Example 1 which concerns on this invention. It is a top view of the caulking spatula of Example 2 which concerns on this invention. It is the top view and side view of the common caulking spatula used conventionally. It is a figure which shows the bowl-shaped curved spatula seen in a prior art document.

It is a figure which shows the finishing condition by a protruding corner part and the conventional caulking spatula. It is a figure which shows the finishing condition by a protruding corner part and the caulking spatula of this invention. It is a figure which shows the variation of a rubber spatula.

Examples for carrying out the invention are shown in Examples 1 and 2.

A first embodiment of the present invention is shown in FIG.
The caulking spatula 1000 of the present invention is composed of a spatula body 1100 made of a thin metal plate and a gripping part 1200 made of wood or synthetic resin. The spatula main body 1100 has four spatula tips 1011, 1012, 1013, and 1014 that are orthogonal to each other, forming a rectangular spatula tip 1500.

This rectangular shape is preferably configured so that every spatula makes an angle of 40 to 50 ° with respect to the center of gravity line 1700 that balances the left and right of the entire caulking spatula, but is not limited thereto. .

Of the side edges of the spatula body, one side edge forms a straight line 1040 toward the edge of the spatula, and this straight line part draws an arc shape 1050 to connect gently with one of the rectangular spatula points 1011. It is configured to connect to the spatula tip 1011.

Also, the side edge on the opposite side is curved in an arcuate shape, and this curved portion 1030 draws a reverse arc shape 1060 to connect gently with the other one of the rectangular spatula tips 1014 to draw a spatula tip. It is configured to connect to 1014.

The two arcuate portions 1050 and 1060 form a neck portion between the rectangular spatula tip portion 1500 and the spatula body 1100.

Hereinafter, it will be described how an operator can perform coking work efficiently using the caulking spatula of the present invention.

When there is relatively enough space in the surrounding work space, the worker can use the caulking spatula 1000 of the present invention.
Hold the gripping part 1200 in your hand, select a spatula tip 1012 or 1013 that has a rectangular shape according to the width of the object that needs to be caulked, and press it on the surface of the caulking material. A pressing operation is performed while maintaining a predetermined angle, and the operation is performed by moving in a predetermined direction.

Pressing the caulking spatula that is narrower than the target width without moving the width, and moving it, it will scrape off the caulking material more than necessary, and press the caulking spatula wider than the target width. When this is moved, it is affected by unevenness of the unevenness of a wide range of the object, so that a uniform pressing force is not applied to the coking surface and bubbles and voids cannot be reliably removed.

In contrast, the caulking spatula of the present invention can be prepared with two types of spatula width corresponding to the long side and the short side of the rectangular shape, so that the working efficiency is remarkably improved.

The caulking spatula tip of the present invention can be prepared in two different widths, specifically, the long side 1012 is 30mm.
The short side 1013 of around 20mm is the most applicable and convenient. However, it is not limited to 30 mm and 20 mm, 1012 may be a short side, and 1013 may be a long side.

Next, it is a case where the caulking material is filled in the complicated place, but it can be divided into two cases depending on the size of the surrounding work space.

The first case is a case where the filling portion is intricate but there is room in the work space (FIG. 5). In this case, the operator A has the gripping part 1200 and makes good use of the inclination angle of the spatula body and the rectangular spatula and pushes the spatula tip 1012 or 1013 (1013 in FIG. 5) into the interlaced place 5a. In this way, the caulking material 6 is strongly pressed while being supported from below and moved in a predetermined direction, so that excess bubbles and voids can be easily removed. This point is the same work form as the case of the saddle-shaped curved spatula 1 (Patent Document 1) previously proposed.

The second case is the case of the corner 7a (FIG. 6) in which the filling portions of the caulking material are intricate and the work space has no margin. In this case, since the work space is not sufficient even if the saddle-shaped curved spatula 1 is used, the coking process cannot be performed well.

However, even in the case as shown in FIG. 6, when using the caulking spatula 1000 of the present invention as shown in FIG. 7, the worker A holds the gripping part 1200 in his hand and one side in the longitudinal direction of the spatula body. An arcuate portion 1050 or 1060 (1050 in FIG. 7) where the edge straight portion 1040 or the arcuate curved portion 1030 (1040 in FIG. 7) arises due to a gentle connection with the rectangular short side 1011 or long side 1014
Use the to avoid the protrusion of the indoor door frame 7 etc., and use the spatula tip 1011 or 1 that forms a rectangle.
The coking process can be easily performed by bringing 014 (1011 in FIG. 7) into close contact with the object in the corner 7a and performing a pressing operation to move it in a predetermined direction.

When the caulking material 6 filled in the location of the corner 9b where the thick plate material 9a meets as shown in FIG. 9 is used as a target, the spatula tips of the conventional caulking spats 100, 200 and 2 (100 in FIG. 9) are used. Ten
Since 3, 203 and 2b, 2d (103 in FIG. 9) are linear, the finished surface after coking is a flat surface, and the horizontal section of the caulking material is triangular 6a, and the apex portion of the triangle Thinning of the caulking material is inevitable, leaving you worried about long-term use.

Here, when using the caulking spatula 1000 of the present invention as shown in FIG.
Arc-shaped part 1050 or 10 for connecting the spatula body part 1100 and the rectangular spatula tip part 1500
60 (1060 in FIG. 10) is pressed against the caulking material 6 filled in the protruding corner portion 9b, and bubbles and voids are removed by moving in a predetermined direction while maintaining pressing upward or downward, and press processing is performed. Can be completed.

Also in this case, when the arc shapes 1050 and 1060 are arc shapes having different Rs, either one can be selected depending on the size of the protruding corner, so this occurs when the width does not match. It is possible to avoid problems such as unnecessary removal of bubbles and voids due to unnecessary shaving of caulking materials and conversely unevenness of surrounding building materials. However, it is not always necessary to have an R different from the arc shapes 1050 and 1060, and even if the same R is used, there are fewer options for work, but the effect as the caulking spatula of the present invention is not destroyed. Absent.

By processing with the arc shape in this way, the horizontal cross section of the caulking material is 4 semicircles.
6b, and any portion is filled with a sufficiently thick caulking material. Therefore, the horizontal section becomes triangular 6a by the caulking work, and there is no anxiety about long-term use compared to the case of the conventional caulking spatula where the caulking material is partially thin.

Further, the relatively long straight portion 1040 of the caulking spatula of the present invention is effective in the scene shown in FIG. The straight portion 1040 is sufficiently longer than a general caulking spatula width (for example, 103, 203, 303 or 2b, 2d or 1011, 1012, 1013 and 1014). Therefore, since the worker A is working at a high place as shown in FIG. 8 and tries to press and move with a general caulking spatula tip, the pressed location may deviate from the predetermined target. By using the straight portion 1040 on one side edge of the inventive caulking spatula 1000 and moving the object while pressing it, the coking process can be performed without concern.

However, since this work is a work with a wide spatula, it is affected by unevenness of unevenness in a wide range of the target part, resulting in unevenness of unevenness on the finished surface, so it is only for the purpose of removing excess caulking material In order to clean the finished surface, it may be necessary to finish the work again with an appropriate wide caulking spatula.

Note that the straight line portion 1040 is not necessarily a straight line, and may be bent in an arc shape like the side edge on the opposite side. In this case, the effects described in the case of FIG. 8 are lost, but other essential effects of the present invention are not destroyed.

As explained above, by using the caulking spatula 1000 of Example 1 of the present invention, even if the portion filled with the caulking material 6 is wide, narrow, entering corner, exiting corner or working space is narrow,
By using properly the rectangular long spatula, short side spatula, arcuate shape 1050, 1060 at the neck of the spatula, or linear part 1040 at the side edge of the main body, the caulking material can be easily pressed. .

A second embodiment of the present invention is shown in FIG.
The caulking spatula 2000 of the second embodiment is provided with a detachable rubber spatula 1300 on the opposite side of the gripper main body 1100 mounting portion of the gripping portion 1200 of the caulking spatula 1000 of the first embodiment.
The gripping portion 1200 has a hole 1600 sufficient to insert and hold the rubber spatula 1300. In addition, a small hole 1201 for hanging on a wall surface or the like is provided for the convenience of preservation.

The rubber spatula 1300 is detachable because, first of all, the rubber is easily consumed, so that it can be replaced with a spare rubber spatula. The aim is to make the caulking finishing work more efficient by preparing the rubber spatula and selecting and installing the most suitable rubber spatula for the target.

A specific shape of the detachable rubber spatula 1300 is shown in FIG.
In FIG. 11, reference numeral 1310 denotes a side view of the rubber spatula, which is common to the variation of the rubber spatula. The part 1310a is a part inserted into the gripping part of the caulking spatula, and the part 1310b is the spatula part of the rubber spatula.
Reference numerals 1320, 1321, 1322, 1323, and 1324 denote front views of variations of the rubber spatula. 13
20a, 1321a, 1322a, 1323a and 1324a are all inserted into the gripping portion of the caulking spatula, and 1320b, 1321b, 1322b, 1323b and 1324b are all spatula tips of the rubber spatula.

The rubber spatula 1320 has a spatula tip width narrower than the width of the gripping portion insertion portion, 1321 has the same width as the spatula tip width and the gripping portion insertion portion, and 1322 has a spatula tip width larger than the width of the gripping portion. Widely, the width of the spatula is wider than that of the gripping part, and the wide part is shifted to one side.
It is narrower than the width of the holding part and the narrow part is shifted to one side.

The above is only an example of a variation of the rubber spatula, the variation is not limited to this, and any size and shape can be used to achieve efficient work. Effective as a rubber spatula.

The spatula body 1100 of the caulking spatula 1000 is generally formed using a relatively thin metal plate (Patent Documents 1 and 2). The reason for using metal as the material is that it can be operated with the same feeling as a traditional plastering instrument and is less likely to break.

A skilled person with sufficient experience can remove bubbles and voids and clean the finish with a spatula made of a metal plate, but the inexperienced person It is difficult to treat the surface of caulking material cleanly with a certain thickness due to the unevenness of the unevenness of the target part and the narrowness of the construction area, and it may damage the surrounding members There was a problem.

In order to solve this problem, it has been proposed that the material of the spatula body be silicon rubber, natural rubber, or a flexible resin material (Patent Document 3). This allows the spatula body to bend and deform according to the level of the operator's force, regardless of the level of skill and unevenness of the unevenness of the target part, and the required amount of caulking material is applied to the target part. It is possible to finish regularly and uniformly.

In this case, it has been proposed that it is desirable to be detachable since soft rubber material is used for rapid deterioration.

In Example 2, the rubber spatula proposed in Patent Document 3 is integrated with the conventionally used metal plate spatula, and any spatula can be used depending on the case.
A specific use example will be described below.

Among the building materials, caulking material is filled in the gaps where metal, glass, etc. with high smoothness, or even wooden objects with relatively high hardness and high smoothness are connected to each other If this is the case, working with the spatula tips 1011, 1012, 1013, or 1014 made of a metal plate can accurately remove excess bubbles and voids, and the finish can be finished sufficiently finely.

However, when caulking material filled with joints of multiple composite panel materials that do not have sufficient smoothness is used, the use of a metal plate spatula will affect the unevenness of the unevenness of the target member. However, bubbles and voids cannot be sufficiently removed, and the smoothness of the surface of the caulking material cannot be sufficiently maintained, so that the appearance is not beautiful.

In such a case, if the rubber spatula 1300 is used, the displacement of the spatula due to unevenness of the unevenness of the target member is absorbed by the flexibility of the rubber, and the position of the entire spatula is kept constant, so the caulking material A certain pressing force is applied, bubbles and voids inherent in the caulking material can be surely removed, and the smoothness of the finished surface can be sufficiently maintained.

In Example 2 of the present invention, by having both the spatula tip 1100 made of a thin metal plate and the rubber spatula tip 1300, the portion filled with the caulking material is wide, narrow, Even with a wide variety of corners, protruding corners, narrow spaces in the work space, and uneven joints such as plywood panels, one caulking spatula 2000 of the present invention can be used reliably. Caulking process can be performed.
