Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, when attaching a curing sheet to the floor, it is necessary to attach it while pulling with a certain tensile strength, and moreover, the roll-shaped curing sheet has a considerable weight. Therefore, it is difficult to perform the work alone. Further, when using the curing material applicator described in Patent Document 1, although both side portions of the curing sheet can be brought into close contact with the floor surface, other portions cannot be brought into close contact with the floor surface. Therefore, after attaching the curing sheet to the floor surface using the curing material applicator, it is necessary for an operator to press and adhere the curing sheet to the floor surface.

[0006] The present invention aims to solve these problems and provide a protective sheet attachment device that makes it possible to easily attach protective sheets to floor surfaces. [Means for solving the problem]

[0007] To achieve the above objective, the present invention comprises the following configuration.

[0008] (1) A support frame (for example, support frame 10) made of single pipes made of steel, A support shaft (for example, support shaft 20) that rotatably supports a rolled protective sheet, A pair of support members (for example, support member 30) are attached to the support frame and detachably support both ends of the support shaft, The system includes a roller body (for example, roller 40) attached to the support frame and having a length greater than or equal to the width of the protective sheet, The support frame has a rectangular frame portion (e.g., frame portion 11) formed by a pair of opposing long pipe portions (e.g., long pipe 11a) and a pair of opposing short pipe portions (e.g., short pipe 11b), and a rod-shaped operating portion (e.g., operating portion 12) extending perpendicularly from the center of one of the pair of long pipe portions to the other long pipe portion. The pair of receiving members are fixed to the center of a pair of opposing short pipe sections in the frame, The support shaft is positioned inside the frame portion by the pair of receiving members. The protective sheet application device is characterized in that the roller body is supported by the other long pipe section of the pair of long pipe sections.

[0009] According to (1), by attaching the rolled protective sheet to the support frame, pulling out the protective sheet and positioning the leading edge of the protective sheet near the roller body, and moving the protective sheet application device, it becomes possible to apply the protective sheet to the floor surface, and these operations can be performed by one person. In this way, it becomes possible to easily apply the protective sheet to the floor surface, and the work of applying the protective sheet to the floor can be done by one person. In addition, the support frame is made of steel and is relatively heavy. Therefore, it becomes possible to press a wide area of ​​the protective sheet against the floor surface via the roller, making it possible to make the protective sheet adhere tightly to the floor. In this way, it becomes possible to easily apply the protective sheet to the floor surface.

[0010] (2) The protective sheet attachment device in (1), further comprising movement restricting members (for example, screws 50, nuts 51) attached to the pair of short pipe sections and in contact with the lower part of the pair of receiving members to restrict movement along the short pipe sections.

[0011] According to (2), the movement restricting member abuts against the lower part of the support, restricting downward movement along the short pipe section of the support. As a result, the support can be placed in a fixed position on the short pipe section. This makes it possible to position the support shaft in a fixed position, to position the rolled protective sheet in a fixed position, and to stably attach the protective sheet to the floor surface.

[0012] (3) A protective sheet application device characterized in that, in (1) and (2), it further comprises lateral roller bodies that are rotatably attached to each of the pair of short pipe sections and are positioned below each of the pair of receiving devices.

[0013] According to (3), when the curing sheet supported by the support shaft is displaced left and right, the curing sheet contacts the side roller 41. At this time, as the curing sheet 100 is pulled out, the side roller rotates. As a result, the curing sheet is more easily pulled out, the rotation of the curing sheet is reduced from stopping, and the curing sheet can be stably attached to the floor surface.

Effect of the Invention

[0014] According to the present invention, it becomes possible to provide a curing sheet applicator that enables the curing sheet to be easily attached to the floor surface.

Modes for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0017] FIG. 1 is a perspective view schematically showing the appearance of the health care sheet applicator 1 according to an embodiment of the present invention. FIG. 2 is a perspective view showing a state in which a roll-shaped health care sheet 100 is attached to the health care sheet applicator 1 of FIG. 1. FIG. 3 is a front view of FIG. 2.

[0018] [Basic configuration of the health care sheet applicator 1] The health care sheet applicator 1 is used for the operation of attaching a roll-shaped health care sheet 100 to the floor. As shown in FIG. 1, it includes a support frame 10, a support shaft 20, a receiver 30, a roller 40, and side rollers 41.

[0019] The support frame 10 has a frame portion 11 and an operation portion 12. The frame portion 11 is composed of two long pipes 11a, 11a made of single steel pipes and short pipes 11b, 11b, and is configured in a rectangle by welding the ends of the long pipes 11a, 11a and the ends of the short pipes 11b, 11b. The long pipe 11a is longer than the width of the health care sheet 100, and the short pipe 11b is set to be longer than the diameter of the roll-shaped health care sheet 100. Thread holes 11c, 11c for passing a screw 50 are formed in the central portions of the short pipes 11b, 11b.

[0020] The operation portion 12 is a long member composed of a single steel pipe of the same steel material as the frame portion 11. The base end portion of the operation portion 12 is connected by welding to the center in the longitudinal direction of one long pipe 11a, and extends in a direction perpendicular to the long pipe 11a toward the outside of the frame portion 11. That is, the operation portion 12 extends parallel to the short pipe 11b and in the opposite direction to the short pipe 11b.

[0021] The support shaft 20 supports the roll-shaped health care sheet 100, and is a rod-shaped steel material that is longer than the width of the health care sheet 100 and shorter than the long pipe 11a.

[0022] The support bracket 30 is rotatably positioned in the center of the longitudinal direction of the short pipe 11b and detachably supports the end of the support shaft 20. The support shaft 20 is supported at both ends by two support brackets 30, 30 positioned on the two short pipes 11b, 11b. The support shaft 20, supported by the two support brackets 30, 30, is positioned inside the frame section 11 and is parallel to the two long pipes 11a, 11a.

[0023] The roller 40 is made of a cylindrical steel pipe that is inserted into the other long pipe 11a. The roller 40 is rotatably supported on the other long pipe 11a. When the support shaft 20 into which the rolled protective sheet 100 is inserted is mounted on the support frame 10, the protective sheet 100 and the roller 40 are parallel to each other. The roller 40 may also be fixed to the long pipe 11a.

[0024] The lateral roller 41 consists of cylindrical steel pipes that are inserted into the two short pipes 11b, 11b respectively. The lateral roller 41 is positioned between the fixing portion of the support 30 on the short pipe 11b and the connection portion with the long pipe 11a, and is rotatable in the circumferential direction of the short pipe 11b.

[0025] Figure 4 is an explanatory diagram showing the configuration of the support 30, where Figure 4(a) is a side view, Figure 4(b) is a front view, and Figure 4(c) is a top view. The support member 30 has a cylindrical fixing portion 31 and a receiving portion 32 extending perpendicularly from the center of the fixing portion 31 to the central axis of the fixing portion 31. The end face of the receiving portion 32 is U-shaped with the top open. The width of the inner walls of this U-shape is set to be approximately the diameter of the support shaft 20, and the end of the support shaft 20 is detachably attached to the receiving portion 32.

[0026] When assembling the protective sheet application device 1, first, the operating part 12 is fixed to one long pipe 11a, the receiving parts 30 and side rollers 41 are inserted into the two short pipes 11b respectively, and the roller 40 is inserted into the other long pipe 11a. Next, the two long pipes 11a, 11a and the two short pipes 11b, 11b are connected to form a rectangle. Next, the receiving parts 30 and side rollers 41 are slid so that the screw holes 11c between the receiving parts 30 and the side rollers 41 are visible, screws 50, 50 are passed through the screw holes 11c, 11c of the two short pipes 11b, 11b respectively, and the ends of the screws 50 are tightened with nuts 51, 51. As a result, the lower part of the support 30 comes into contact with the head of the screw 50 or the nut 51, restricting the movement of the support 30 and positioning it in the center of the longitudinal direction of the short pipe 11b. Next, the two support 30s are rotated so that the receiving parts 32 face each other. Then, both ends of the support shaft 20 are inserted into the receiving parts 32 from above. This assembles the protective sheet attachment device 1 as shown in Figure 1.

[0027] When using the protective sheet attachment device 1, the support shaft 20 is first removed from the receiving parts 32, 32, inserted into the central hole of the rolled protective sheet 100, and then both ends of the support shaft 20 are inserted into the receiving parts 32, 32. As a result, the protective sheet 100 is attached to the protective sheet attachment device 1, as shown in Figure 2.

[0028] [How to use protective sheet application tool 1] Figure 5 is a schematic side view showing how the protective sheet attachment device 1 is used in one embodiment of the present invention. For the sake of explanation, the direction of the arrow in the figure will be referred to as the front, and the opposite direction as the rear.

[0029] Figure 5(a) shows the case of attaching a protective sheet 100, which has an adhesive layer formed on its surface, to the floor surface. When the protective sheet 100, which has an adhesive layer formed on its surface, is attached to the protective sheet attachment device 1, the tip of the protective sheet 100 is pulled downward from the front so that the adhesive surface faces forward, and it is attached from the front of the roller 40 to the area between the roller 40 and the floor surface. Then, the worker pushes the protective sheet attachment device 1 forward to move the roller 40 forward. For example, as shown in Figure 6, the worker can move the roller 40 forward by holding the operating part 12 and kicking the area near the base of the operating part 12 with their foot. At this time, the roller 40 rotates and attaches the protective sheet 100 to the floor surface. Each time a protective sheet 100 is attached to the floor surface, the protective sheet is pulled out from the rolled protective sheet 100, and the rolled protective sheet 100 rotates clockwise in Figure 5(a).

[0030] Figure 5(b) shows the case of attaching a protective sheet 100, which has an adhesive layer formed on the back, to the floor surface. When the protective sheet 100, which has an adhesive layer formed on the back, is attached to the protective sheet attachment tool 1, the front end of the protective sheet 100 is pulled downwards from the rear, the adhesive surface is turned forward, and it is attached from the front of the roller 40 to the area between the roller 40 and the floor surface. Then, the worker pushes the protective sheet attachment tool 1 forward, moving the roller 40 forward. At this time, the roller 40 rotates and attaches the protective sheet 100 to the floor surface. Each time the protective sheet 100 is attached to the floor surface, the protective sheet is pulled out from the rolled protective sheet 100, and the rolled protective sheet 100 rotates counterclockwise in Figure 5(b). In this way, by using the protective sheet attachment tool 1, it becomes possible for one person to perform the work of attaching the protective sheet 100 to the floor.

[0031] The lateral rollers 41, 41 prevent the rotation of the protective sheet 100, which is supported by the support shaft 20, from stopping even if the sides of the rolled protective sheet 100 or the pulled-out protective sheet 100 adhere to the short pipes 11b, 11b. In other words, when the protective sheet 100 supported by the support shaft 20 shifts from side to side, the protective sheet 100 comes into contact with the lateral rollers 41 and adheres. At this time, as the protective sheet 100 is pulled out, the lateral rollers 41 begin to rotate. This makes it easier to pull out the protective sheet 100 and maintains its rotation.

[0032] [Effects and Effects] As described above, this embodiment provides the following effects and advantages. According to the protective sheet application device 1 of this embodiment, the protective sheet 100, which is wound in a roll, is attached to the support frame 10, and the protective sheet 100 is pulled out and positioned so that the leading edge of the protective sheet 100 is near the roller 40. Then, by moving the protective sheet application device, it becomes possible to apply the protective sheet to the floor surface. These operations can be performed by one person. Therefore, it becomes possible to easily apply the protective sheet 100 to the floor surface, and the work of applying the protective sheet 100 to the floor can be performed by one person.

[0033] Furthermore, according to this embodiment, the protective sheet application device 1 is mainly composed of single-pipe steel components and is relatively heavy. Therefore, it is possible to press a wide area of ​​the protective sheet 100 against the floor surface via the roller 40, making it possible to adhere the protective sheet 100 tightly to the floor. In this way, it becomes possible to apply the protective sheet 100 stably to the floor.

[0034] Furthermore, according to this embodiment, the lateral roller 41 is rotatably attached to the short pipe 11b, and when the protective sheet 100 supported by the support shaft 20 shifts from side to side, the protective sheet 100 comes into contact with the lateral roller 41. At this time, as the protective sheet 100 is pulled out, the lateral roller 41 rotates. This makes it easier to pull out the protective sheet 100, reduces the likelihood of the protective sheet 100 stopping its rotation, and enables stable application of the protective sheet to the floor surface.

[0035] Furthermore, according to this embodiment, the screw 50 and nut 51 abut against the lower part of the support 30, restricting the downward movement of the support 30 along the short pipe 11b. Therefore, even if the support 30 moves along the short pipe 11b, the support 30 can be placed in a fixed position on the short pipe 11b. This makes it possible to position the support shaft 20 in a fixed position, to position the rolled protective sheet 100 in a fixed position, and to stably attach the protective sheet to the floor surface.

[0036] Although embodiments of the present invention have been described above, the embodiments of the present invention are not limited to those described above. For example, in the embodiments described above, the receiving member 30 is configured in a T-shape, but it is not limited to this, and may be configured as the receiving member 35 shown in Figure 7.

[0037] Figure 7 is an explanatory diagram showing the configuration of the receiving device 35 related to the protective sheet application device 1 in another embodiment of the present invention, where Figure 7(a) is a side view and Figure 7(b) is a top view.

[0038] As shown in Figure 7(a), the support 35 has a cylindrical portion 35a that can be attached to the end of the support shaft 20, and a semi-cylindrical portion 35b that is connected to the end of the cylindrical portion 35a. The semi-cylindrical portion 35b is connected to the end of the cylindrical portion 35a opposite to the end that is attached to the support shaft 20. Furthermore, the curvature of the inner surface of the semi-cylindrical portion 35b is the same as that of the short pipe 11b, and the central axis of the semi-cylindrical portion 35b extends perpendicular to the central axis of the cylindrical portion 35a.

[0039] Alternatively, the support shaft 20 may be attached to the support frame 10 by mounting the support fittings 35 to each end of the support shaft 20 and fitting the semi-cylindrical parts 35b, 35b to the short pipes 11b, 11b, as shown in Figure 7(b). [Explanation of Symbols]
