Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trowel for continuous application for continuously applying a fluid building material such as mortar, plaster, plaster and other plastering materials.

[0002]

2. Description of the Related Art The inventor of the present application has hitherto continuously discharged a building fluid material such as a mortar material from a trowel,
We have been developing it with the aim of commercializing a continuous coating system that uses a trowel that enables coating. This system pressure-feeds a fluid material such as mortar from a pump and discharges it from a continuous coating iron through a hose. The fluid material is continuously applied so as to spread on the application surface. The development of this system was difficult to put into practical use because it encountered various problems with respect to various elements such as pumps, fluid materials, irons, etc. Became possible. Among various problems, the problem with the iron is poor operability, and in particular, it requires a force that makes the operator feel "heavy" compared to the operation of a normal iron. was there. In order to solve this problem, the inventors of the present invention have made various studies, and as a result of the following reasons, it has been found that the iron operation requires a force and the operability deteriorates to the extent that the operator feels “heavy”. .

That is, the trowel for continuous coating at the beginning of development is a trowel plate, an opening provided in the trowel plate, a communicating portion provided on the upper surface of the opening, and a grip portion provided in the communicating portion. It is equipped with a hose connected to this communicating part or handle part and sends the building fluid material from the above opening to apply the same material to the application surface with the iron plate. However, the communication portion having the grip portion and the iron plate are directly connected to each other, and the rigid member is not deformable from the communication portion to the iron plate. On the other hand, in the ironing work, the iron is moved left and right over the entire body of the worker to apply a fluid material such as mortar, but when turning left and right, compared to normal straight operation I needed a lot of power. Specifically, when advancing the iron to the right, apply more force to the left side of the iron plate than to the right side, and in some cases lift the right side slightly, and as a left side load, push from the left to the right. Advance the iron. And
When advancing to the left, the opposite is true and the load is on the right.
When switching from rightward to leftward, while finely adjusting the force applied to the handle, move the handle from the left side to the right side to shift from the left load to the right load (extremely, the state of the iron plate floats to the right. (From a slight state to a state of floating to the left)
Try to change. However, in the case of the iron for continuous application, a hose is connected and the pressurized fluid building material flows in this hose, so the upper end of the iron is semi-fixed by the hose. Will end up. As a result, it is difficult to move the handle from the left side to the right side in order to perform the turning operation of the trowel, which requires force. In particular, in the case of mere rightward movement or leftward movement, only parallel movement is required. Therefore, the parallel movement of the handle portion does not require a large force, but in the case of turning back, the force for rotating the handle portion is required. Therefore, it was found that the load of the force was extremely large when the upper end side of the iron was semi-fixed by the hose.

The trowel for continuous application according to this embodiment is such that a building fluid material such as mortar is applied to a wall surface or the like while being continuously discharged, and is shown in FIG. Thus, the iron plate 1, the communication portion 2 provided above the iron plate 1, and the grip portion 3 provided on the communication portion 2 are provided. The communication part 2 has a rotating part 4 and a connecting part 5 above it.
And a hose 6 is connected to the connecting portion 5. The base end of the hose 6 is connected to the hopper 8 via the pump 7. The building material such as mortar put into the hopper 8 is pumped by the pump 7 and the communication part 2 from the hose 6 is connected.
Leading to.

As shown in FIG. 4, an opening 11 penetrating vertically is formed in the iron plate 1 substantially at the center thereof.
The building material that has been pumped is discharged from the opening 11 to the lower surface of the iron plate 1, and by the ironing work of the worker,
It will be painted on the wall.

In such a continuous coating iron, the greatest feature of the present invention is that the communicating portion 2 and the iron plate 1 are connected so that the angle can be changed. That is, the elevation angle of the communication part 2 with respect to the iron plate 1 changes, and in this example, by providing the deformable flexible conductive path 9 between the communication part 2 and the iron plate 1, the fluid material is changed. In addition to being capable of feeding, the elevation angle of the communication portion 2 with respect to the iron plate 1 is changed.

First, the iron plate 1 is formed of a material and a shape such as metal or synthetic resin used for a normal iron, and an opening 11 is formed in the center thereof. In this example, as shown in FIG. 2, the opening portion 11 includes a central opening portion 12 provided directly below the communication portion 2 and front and rear opening portions 13 and 14 continuously provided in the front and rear portions of the central opening portion 12. And the fluid material ejected from the communicating portion 2 is ejected so as to spread in the front and rear direction. The front and rear opening portions 13, 14 preferably have a larger opening area than the central opening portion 11. Although the trowel plate 1 has a triangular shape at the front, as shown in FIG. 1, the trowel body 1 has a rectangular shape without the triangular part 1a. Various modifications can be implemented.

Next, the flexible conducting path 9 is composed of a rubber-made tubular body having elasticity as a whole, and its lower end is fixed to the iron plate 1 and its upper end is fixed to the lower end of the communicating portion 2, respectively. There is. The flexible conducting path 9 has an opening 1
It is formed to correspond to the shape of No. 1, and in this example, it is a tubular body having a substantially rectangular cross section with a front-rear length smaller than the lateral width. The flexible conduit 9 has flanges 9 above and below it.
1, 92 are formed. The material of the flexible conducting path 9 can be formed of cloth, synthetic resin, or a composite material thereof in addition to rubber, and is flexible so that the angle between the communication path 2 and the iron plate 1 can be changed. A flexible material having flexibility, flexibility, or elasticity, which can be appropriately selected and used, provided that the fluid material does not leak outside. Further, it is not necessary to form the entire flexible conductive path 9 with the same material, and at least only the bent portion is formed with the above material, and the rigid portion with respect to the communication path 2 and the iron plate 1 has other rigidity. You may use the material etc. which have. In addition, in terms of smoothness of passage of the fluid material, it is desirable that the inner peripheral surface of the flexible conducting path 9 be flat, but the flexibility may be enhanced by forming it into a bellows shape or the like.

The communication passage 2 has a tubular portion 2 as shown in FIG.
1 and a reservoir 22 that spreads to the lower end side thereof. The reservoir 22 has a large cross-sectional area corresponding to the opening 11. The flowable material flowing from the tubular portion 21 spreads over the entire reservoir 22, is temporarily stored in the reservoir 22, and then is discharged from the entire opening 11. A flange 23 is provided at a lower end of the communication passage 2 (a lower end of the reservoir 22), and an upper flange 91 of the flexible conduction path 9 is fixed to the flange 23 with a screw 93. The lower flange 92 is fixed to the iron plate 1 with screws 94. These screws 93 and 94 are
It is screwed into a stud bolt (not shown) provided upright on the communication passage 2 and the iron plate 1. Specifically, each stud bolt (not shown) is passed through a hole (not shown) provided in the upper and lower flanges 91 and 92 of the flexible conduction path 9, and packing, a washer, etc. are arranged as necessary. The screws 93 and 94 are used to fix them.

The communication passage 2 is provided with a handle portion 3 for holding the iron. In this example, one handle part 3 is provided behind the tubular part 21, but as shown by the chain double-dashed line in FIG. 1, a handle part 31 is also provided on the front side. It should be provided.

A bent connecting pipe 23 is provided above the communication passage 2.
Is provided, and the connecting pipe 23 and the tubular portion 21 are rotatably connected via the rotating portion 4. This allows
The direction of the hose 6 connected by the connecting portion 5 changes with respect to the connecting pipe 23.

The connecting portion 5 has a connecting structure as shown in FIG. In this example, a nut 51 screwed onto the upper end of the connecting pipe 23, a ring 52 disposed on the upper end of the nut 51, and elasticity arranged between the ring 52 and the upper end of the connecting pipe 23 are provided. It is composed of an outer tube 53 and an elastic inner tube 54 arranged on the inner peripheral side thereof. Then, by tightening the nut 51 through the hose 6, the gap between the ring 52 and the connecting pipe 23 is narrowed, whereby the central portion of the outer pipe 53 bulges radially inward and is pushed by this. The central portion of the inner pipe 54 also bulges in the radial direction, and the hose 6 is fixed by being tightened. The advantage of this connection structure is that a connection structure with high liquid tightness can be obtained only by tightening the nut 51 through the hose 6, but this connection structure can be modified in various ways. Further, in this embodiment, the communication passage 2
Although the hose 6 is connected to the hose 6, the hose 6 is connected to the handle 3 by connecting the handle 3 in the form of a hollow tube to the handle 3, and the fluid material is discharged from the opening 11 through the connector 2. You may do it.

In the trowel for continuous coating having the above structure, the fluid material is continuously discharged from the opening 11 of the iron plate 1 and is spread on the surface to be coated such as a wall surface. This enables the fluid material to be applied efficiently. As mentioned above, in the ironing work, the iron is moved left and right on the entire surface of the worker's body, but when turning from rightward to leftward, the handle is left side while finely adjusting the force applied to the handle. To move to the right to change the state of the iron board from the state of floating right to the state of floating left. At that time, when the right side load is applied as shown in FIG. 6 from the neutral state of FIG. 3, one side wall (the right wall surface 9a in this example) of the flexible conductive path 9 is bent so that its height becomes low. The communication portion 2 and the handle portion 3 provided on the communication portion 2 are tilted to change the elevation angle α, whereby the center of the handle 3 moves from the center of the iron plate 1 to the right side, and the right side is easily changed. It can be a load. In this example, since the left and right sidewalls of the flexible conducting path 9 extend in the front-rear direction, it is more preferable that the left and right sidewalls of the flexible conducting path 9 be parallel to the center line extending in the front-rear direction of the iron plate 1. Since the communication portion 2 and the grip portion 3 provided on the communication portion 2 are formed, the communication portion 2 can be easily bent in the left-right direction with respect to the iron plate 11.

FIG. 7 schematically shows this movement. As shown in FIG. 7A, the position of the upper end of the communicating portion 2 (that is, the position of the connecting portion 5 with respect to the hose 6) does not change. Both can be changed from the neutral state shown by the solid line to the right side load. More specifically, when the handle portion 3 is moved from the neutral state (solid line) to the left side (two-dot chain line), the right wall surface 9a of the flexible conducting path 9 bends, and thus the communication portion 2
The position can be moved without changing the position of the upper end (that is, the position of the connecting portion 5). In this example, the load changed by the angle β. Thus, in the present invention, the hose 6
Since the load can be changed without changing the position of
It is thought that it is possible to prevent the operator from feeling “heavy”. On the other hand, FIG. 7B shows a case where the flexible conduction path 9 is not provided, and in this example, in order to change from the neutral state (solid line) to the right side load state (two-dot chain line) by the angle β, , The position of the upper end of the communication part 2 (that is,
It is necessary to greatly change the position of the connecting portion 5 with respect to the hose 6. More specifically, in this example, it is necessary to directly move the iron plate 1 in order to change the load without the flexible conduction path 9. That is, in order to shift the load from neutral to the right side, a movement to raise the left side of the iron plate 1 is required, and for that movement, the position of the upper end of the communication portion 2 (that is, the hose 6
It is necessary to change the position of the connecting portion 5) to the right side largely. Here, as described above, since the fluid material is fed under pressure to the hose 6, when the hose 6 is moved by rotating the handle portion 3, a force is required and the operator It makes you feel "heavy".

The above description with reference to FIG. 7 is a simplified description of the complicated ironing operation by a skilled worker.
In order to accurately reproduce the ironing operation, it is necessary to perform a more detailed analysis, but when a skilled worker continuously performs ironing work using the iron of the present invention, the ironing operation is easy and efficient. It was confirmed that specific work was realized.

In particular, in this embodiment, the screws 93 and 94 at the positions corresponding to the upper and lower sides of the flexible conduction path 9 come into contact with each other, so that the communication portion 2 is rotated with respect to the iron plate 1. And stops at a predetermined elevation angle α.
Therefore, in this example, the screws 93 and 94 serve as angle restricting means for the elevation angle α, and it is possible to prevent the elevation angle α from changing more than necessary. In addition, in this example, the upper and lower screws 93 and 94 serve as an angle restricting means, and at least a part of the force from the handle portion 3 is transmitted to the iron plate 1 by the contact between the screws 93 and 94, so that the iron plate 1 can be securely connected. The right side load can be set. The elevation angle α may be set freely within the range allowed by the operability, but is preferably 45 degrees or more, and more preferably 30 to 10 degrees. As described above, both screws 93 and 94 act as a contact serving as an angle restricting means, but the same result can be obtained by providing a separate contact other than this screw. Also, the flexible conductive path 9 having elasticity such as rubber
Alternatively, the communication portion 2 and the iron plate 1 may be connected by a rotatable pipe joint, and a means for restricting the rotation angle may be provided. It is also desirable that the hitting and angle regulating means be able to change the hitting position and angle by adjusting with a screw or the like.
