In the above putty application work, putty is put on the wall surface, putty is applied in the inside of the groove and the like, and furthermore, the surface is smoothed all by hand. In particular, the work of embedding the putty in the groove has a problem that a burden is imposed on the wrist, resulting in heavy labor and complicated work.

[0004] In the case of manual work, work up to finishing is performed within a certain narrow work range, and the process moves to the next work range. For this reason, when the wall surface or the like has a water-absorbing property such as a gypsum board, there is a problem that the putty becomes thin after finishing the finishing work. Therefore, the present invention proposes a putty applicator that can efficiently perform putty applying work and solve the problem of putty thinning.

[0005]

According to the present invention, there is provided a putty applicator comprising: a main body having a putty material storage chamber; a roller having a roller body disposed in a horizontal axis in front of the main body; A wheel leg that protrudes and turns in the same direction as the roller body communicates with the putty storage chamber of the main body, and the tip is a roller when the roller body and the wheel leg abut on the coating surface. A nozzle portion that is open to the coating surface that is a moving surface of the roller body in the vicinity of the body, and an extrusion mechanism portion that has an operation handle and extrudes the putty material in the putty material storage chamber toward the nozzle portion side. It is characterized by doing.

Accordingly, the putty material having fluidity is put into the storage room, the roller portion and the wheel leg portions are moved in contact with the putty coating target wall surface in the coating direction, and the operation handle of the pushing mechanism portion is moved. When the putty material is pushed out of the storage chamber into the nozzle section by operation, the putty material is extruded to the wall surface from the opening of the nozzle section, and is smoothly applied by the roller section. It is done at the same time.

[0007]

Next, an embodiment of the present invention will be described. The putty applicator shown in the embodiment includes a main body 1,
The main body 1 includes a roller section 2, a wheel leg section 3, a nozzle section 4, and an extruding mechanism section 5. The main body section 1 has an elongated box shape, has a storage chamber 11 in the main body, and puts putty material on the upper surface. And an opening / closing door 12 is provided, and the other parts 2, 3, 4, and 5 are additionally provided.

The roller 2 has a support arm 21 of an appropriate length projecting from the front side of the main body 1 and a horizontal shaft 22 connected to the support arm 21 in parallel with the front surface of the main body. A roller body 23 is rotatably mounted on the roller 22. The roller body 23 has a cushion material 24 such as a sponge inside, and a surface covered with a rubber body 25.
In particular, the rubber body 25 is provided with a fine groove pattern (C-shape with respect to the direction of rotation) on the surface, and the side surface is covered with the rubber body so that the side end portions are more cushioning than the central portion. It is made. Further, the support arm 21 is attached so as to be freely rotatable in the vertical direction with respect to the main body, and is provided with a projection 26 so that the roller body 23 is pressed downward (toward the coating surface).

The wheel leg 3 is formed by rotatably mounting a wheel 32 on a bearing 31 projecting from the front bottom surface of the main body 1. In particular, when the roller body 23 and the wheel 32 are brought into contact with the coating surface A, the main body 1 is inclined obliquely (about 45 degrees) with respect to the coating surface A, and The sizes and positions of the roller body 23 and the wheels 32 are determined so that the nozzle unit 4 described later can be sufficiently arranged. Wheel 32
If a ridge is provided in the center of the gypsum, the ridge fits into a groove such as a joint of the gypsum board to assist the traveling in a certain direction.

[0010] The nozzle section 4 is provided on the front face of the main body section 1 with the storage chamber 1.
1 and is provided so as to communicate with
Is provided in the vicinity of the roller body 23 and toward the application surface which is the moving surface of the roller body 32, and particularly when the roller body 23 and the wheel 32 are brought into contact with the application surface A. It has a shape that is opened by a parallel cut a close to the surface A and a cut b rising from the parallel cut a on the roller body 23 side of the parallel cut a. In addition, if the nozzle part itself is detachable such as screw mounting to the main body,
There is an advantage that cleaning after use is easy.

The extruding mechanism 5 includes a putty material B in the storage chamber 11.
Plate 51 which presses the nozzle portion 4 side, a rack bar 52 continuously provided on the back surface of the extrusion plate 51, and a rack bar 52 provided on the back surface of the main body 1 to support the rack bar 52 and
A gripping portion 53 provided with a retraction preventing mechanism (a well-known ratchet mechanism capable of blocking and releasing blocking), and an operating handle 54 for applying the advancing operation force of the rack bar 52 with the distal end of the gripping portion 53 as a stop. Is done. Reference numeral 13 denotes a stand for supporting the device with the wheels 32 when the device is not used.

The putty material B having fluidity is stored in the storage chamber 1.
When the roller body 23 and the wheel 32 are brought into contact with the wall surface A to which the putty material B is to be applied, the device is inclined with respect to the wall surface A, and the grip portion 53 and the operation handle 54 are moved. When the operating handle 54 of the push-out mechanism 5 is operated while the device itself is gripped and moved in the coating direction along the wall A, the putty material B is pushed out of the storage chamber 11 to the nozzle portion 4. The putty material B, which is put on the wall surface A and is put on the wall surface A, is smoothly applied by the roller body 23 in a state where the application surface is lightly pressed by the ridge 26. In addition, the putty coating operation is performed continuously over a long working range of about 15 to 20 m, and when the water absorption of the wall surface is completed (when the putty is no longer thin), the finishing operation using the iron is performed. The work efficiency has been remarkably improved, and the problem of putty thinning has been solved.

In particular, since the cut of the opening 41 of the nozzle 4 is a parallel cut a and a front cut b, the putty material B in the nozzle 4 is applied to the wall A at the portion from the parallel cut a. As a result, the front cut b is placed on the applied portion, so that the putty B for filling the groove or the like can be easily placed.

Further, since the roller body 3 itself has a more rigid cushioning property at the side end portions than at the center portion, the putty material B mounted on the wall A has a slightly curved central portion. In this case, the protrusion from the side end portion can be significantly suppressed, and the putty coating operation can be performed more efficiently.

The present invention is not limited to the above-described embodiment, and the structure for pressing the coating surface of the roller portion, the internal structure of the roller body, the shape of the nozzle opening, and the like are arbitrarily adopted. In addition, it goes without saying that the specific structure can be arbitrarily determined as long as the pressing mechanism also exerts a predetermined function.
