BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putty coating machine. More specifically, the present invention is useful for a drywall construction method using a gypsum board, can make the board seam into a beautiful finished state, and has excellent workability,
It concerns a new putty applicator.

[0002]

2. Description of the Related Art In recent years, gypsum board has been recognized for its excellent properties such as fire resistance, sound insulation, heat insulation, ease of construction and economy, and is used for interior decoration of all buildings from houses to skyscrapers. Has been done. When using gypsum board as a base material for interior, the seam is treated,
Its purpose is to 1) eliminate the steps and gaps of the seam to make it smooth, 2) reinforce the seam and prevent the occurrence of cracks, 3) secure the sound insulation performance by the seam treatment, and flame during a fire. Or to block smoke. In order to realize such an object, a dry wall construction method has been established in which a joint is treated with joint cement, that is, putty. Also, the procedure and tools for this method have been devised.

In the dry wall method, usually, as shown in FIG. 9, for example, taper board (a) made of gypsum board is first treated with tape (a) made of glass fiber, cloth or paper. Tension, putty (c) is overcoated with a manual tool called a flat finisher, and after drying, putty (d) is similarly overcoated with a flat finisher, and then sanding or sealer application treatment, before painting etc. It is processing.

Further, in the joint treatment of the cut portion butt portion of the gypsum board, for example, as shown in FIG. 10, a tape (a) is attached and a flat finisher is used to put putty (e), (f), and (ki). Apply sequentially. The flat finisher used at this time, for example, as shown in FIG. 11, stores the putty in the container (service), and the putty is applied to the putty applying port by the push plate (s) connected to the tip of the long handle (si). It is extruded from (C) so that the putty can be applied to the joints. In this coating machine, the push plate (s) is
It is possible to swing back and forth around the rear part of the substantially V-shaped container (service) as a fulcrum, and a pair of return springs (so) are used for pushing plates (s).
It is connected between the upper part of the container and the lower part of the rear side of the container (service), so that the push plate (s) is always pushed back to the rear until it hits the stopper (ta) provided protruding from the side wall of the container (service). The long handle (shi) is detachably attached to the push plate (s).

As shown in FIG. 12, the flat finisher has a wire-shaped or plate-shaped metal piece (chi) inserted through the inside of the long handle (shi), as shown in FIG. ) Is connected to a rotatable link arm (tsu) via a fulcrum, and the lock piece (te) is inserted into and removed from the groove of the side groove plate (g) fixed to the push plate (s). It has been known. This product pulls a metal piece (h) by grasping a hand lever (na) provided at the rear end of a long handle (shi) and rotates a link arm (tsu) to turn a lock piece (te) into a side groove. It is inserted into the groove of the plate (g) so that the push plate (s) can be fixed at an arbitrary specific angle with respect to the handle (si). By doing so, it is possible to move the container (service) to a predetermined portion of the coating operation and to separate it from the predetermined position without hanging.

On the other hand, at the time of coating operation, the hand lever (na) is released and the fixing by the lock piece (te) is released. By doing so, the angle of the handle (shi) with respect to the container (service) at the time of application can be freely set, and the container (service) can be rocked. In a putty applicator known as such a flat finisher, first, the putty is poured into a container (sa), and then, while holding the hand lever (na), hold a long handle (si) with a hand ( ) Is pressed against the joint groove of the gypsum board. Then, release the grip of the hand lever (na) and move the container (sa) up and down or left and right (for walls) or back and forth, left and right (for ceilings).
The long handle (si) pushes the push plate (s) against the action of the spring (so), and swings the push plate (s) toward the front wall of the container (sa), thereby Putting putty on the putty
Push out more.

[0007]

However, in the case of the conventional putty applicator, there is a problem that the operation of the hand lever (na) is not so easy. This is because the hand lever (na) has a limited gripping method, and it takes skill to change the hand lever (na) only at the beginning and the end of applying putty.

Also in that structure, the force transmission mechanism by the metal piece (chi) is indispensable, and since the wire or the plate-shaped metal piece (chi) is inserted from the front end to the rear end of the handle, the handle itself is inserted. It is difficult to make the telescopic type, and even if the telescopic type is used, the structure becomes complicated and the weight becomes heavy. In addition, at the time of work, it was necessary to work by grasping the hand lever (na) at the end of the long handle (shi). Therefore, the conventional putty applicator is not satisfactory in workability.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional putty applicator, has a relatively simple structure, and allows the handle to be of a telescopic type easily. It is an object of the present invention to provide an improved new putty applicator which is excellent in operation workability and can be gripped while working.

[0010]

In order to solve the above-mentioned problems, the present invention provides a putty container portion having a putty coating port on the front surface thereof, and a push plate arranged at the opening of the rear surface portion of the container portion. A putty applicator provided with a push handle connected to the push plate, wherein the push handle is provided with a toothed body, and the push handle has a tubular body angularly attached and fixed to the push plate. A cylindrical body having a slide body that can be moved back and forth, and an elastic body that is biased in the opposite direction to the push plate is connected to the slide body, and the front part thereof has a connecting point. There is a slide arm part that moves the lock arm part back and forth so that it can be inserted into and removed from the toothed body of the push plate.It is inserted into the toothed body by the urging force of the elastic body and is attached to the push plate at a specific angle. When applying putty, the fixed lock arm part is used to slide the push handle and slide arm. Desorbed from the press plate tines by pressing the arm portion, to provide a putty dispenser, characterized in that swinging the putty coating machine by pushing handle.

Further, according to the present invention, in the above putty applicator, a putty blade for smoothing the putty is provided in the front part of the putty application port, and the putty blade is pressed to expand the putty forward. One of the aspects is that a bulge adjusting mechanism for letting it out is provided.

[0012]

In the putty applicator of the present invention, a double structure of a cylinder body and a slide body fixed to a push plate and a slide structure of this slide are used without using a metal piece which is inserted into a hand lever as in the conventional case. Since the lock arm is operated by the slide arm that is connected to the body to fix or release the push handle to the push plate, it is possible to do this by simply pushing in and releasing the push handle. This facilitates the movement of the container to a predetermined site without causing the container to hang, and allows the container to freely swing during application.

Further, in the present invention, there is no problem in making the push handle telescopic. For this reason, it is easy to apply putty, and it is easy to work on a scaffolding such as a stepladder, the work range is wide, and it is easy to follow the step size of the seam of the gypsum board, and it has a beautiful flat surface. The finished state can be obtained. In addition, the putty blade adjusting mechanism enables more appropriate adjustment of the putty amount.

If desired, 6) may have a structure such as a telescopic type, two-stage joint, three-stage joint, etc., and a cap (127) may be attached to the end portion. Further, it is also preferable that the grip portion guide (128) is provided with a fixed position variable by a thumbscrew (129).

For example, the operation of the putty applicator of the present invention exemplified as the above structure will be described below.
As shown in FIGS. 5A and 5B, the operation is as follows. (A) First, during normal non-application, that is, during storage, transportation, or movement of the container (2) to a predetermined application position, the slide body (113) in the tubular body (112) is made of an elastic body ( 114), for example, a coil spring, a disc spring or the like, is urged in the direction opposite to the toothed body (111).

Therefore, the slide arm portion (117) extends in the direction of arrow A in FIG. 5 (a), while the lock arm portion (116) is rotated in the direction of arrow A'and the toothed body (11) is rotated.
It meshes with the tooth profile of 1). Therefore, the push handle (11) is fixed to the fixing plate (9), and by extension, the pressing plate (5) of the container (2) at a specific angle.

In this state, since the container (2) does not hang, it is easy to move by the push handle (11). (B) On the other hand, at the predetermined coating position, the push handle (1
When the slide body (113) of 1) is pushed in, the elastic body (1
Contrary to the urging force of 14), it slides forward by a distance (L), for example. Then, the slide arm part (117)
5 also slides forward in the direction of arrow B in FIG. 5 (b), and conversely, the lock arm portion (116) rotates in the direction of arrow B'and the engagement with the toothed body (111) is released. .

In this state, the container (2) of the putty applicator
Since the can be freely swung with respect to the push handle (11), the putty applying work can be smoothly performed. Of course, when the putty applying work is finished, the state of (a) is brought about, so that the work can be finished while scraping off the extra putty from the wall surface or the ceiling surface.

Although the present invention is essentially defined by the above characteristics, the putty coating machine further includes:
It is also advantageous that the application part has the following features. That is, first, the container (2) illustrated in FIG.
The putty blade (4) arranged on the front surface may be allowed to swell by a swelling adjusting screw mechanism (40), for example, as illustrated in FIG. The screw mechanism (40) is arranged substantially at the center of the putty blade (4), and both sides of the putty blade (4) are fixed to the putty container portion (2) with screws.

That is, for example, dial (41) A
When rotated in the direction, the double nut (42) rotates, and the double nut (42) presses the putty blade (4) to bulge forward. Then, the both sides fixed to the putty container part (2) by the screw remain as they are, but the putty blade (4) is extruded in the forward B direction and bulges out at a substantially central part, and a slight gap (t) is formed. Will occur. Then, the applied amount of putty can be increased in this portion. Therefore, for example, even if the seam of the gypsum board has a large step, the gap (t) formed by the bulging of the putty blade (4) facilitates the follow-up of the large step of the putty application and is flat and beautiful. Joint treatment is possible.

Of course, the dial (41) may be arranged not on the outside of the putty blade (4) but between the putty container portion (2) and the putty blade (4) as illustrated in FIG. Good. In this example, for example, by rotating the dial (41) in the A direction, the screw (43) inserted into the female screw of the putty container portion (2) is rotated, and the dial (41) is rotated.
Causes the putty blade (4) to be pushed forward in the direction B to swell. Then, the putty blade (4) is curved like a bow in the substantially central portion, and a gap (t) is generated. This gap (t) controls the amount of putty applied, and the putty blade (4)
Make the break-in appropriate.

In any of the arrangements, the amount of putty applied can be more easily adjusted by the swelling of the putty blade (4). Also, the width of the putty coating can be easily adjusted in the present invention. This is because, as for the putty applying port (3), as shown in FIG. 8, the opening plate body (31) having various opening sizes is screwed into the putty container part (2) by the metal fitting (32). This is because the putty coating port (3) having various opening widths can be formed only by stopping.

When the opening plate body (31) is attached, if the opening width is small, the flow of the putty in the lateral direction cannot be avoided, so that a flow prevention plate may be attached. Of course, the putty blade (4) may be provided with bulge adjusting screw mechanisms (40) at a plurality of locations. That is, in addition to fixing with fixing screws on both sides, a wide blade (4) is provided with bulge adjusting screw mechanisms at a plurality of positions thereof, and these can be adjusted simultaneously or separately as necessary. You can Then, it is possible to bulge out only one place, and it becomes possible to apply putty to the required width. Of course, a wider width can be adjusted.

Regarding the injection of putty, the pressing plate (5) may be opened and put in the putty container part (2),
The putty application port (3) or its open state may be put in the container. Needless to say, the putty applicator of the present invention is not limited to the above-mentioned example, and various aspects can be made in its details.

[0032]

As described above in detail, according to the present invention, the handle is pushed and released without the conventional structure in which the handle and the putty applicator container are fixedly adjusted by the hand lever attached to the handle. Since the handle can be adjusted only by itself, it is easy to improve workability by making the handle itself a telescopic type or a multistage type, and the way of holding the handle is not limited. Further, since the structure is simple, maintenance is easy and the weight can be reduced.
