Abstract
Description
[Technical field]
[0001] The present invention relates to a fixing tool for fitting and fixing airtite rubber into a groove. [Background technology]
[0002] Airtight rubber is fitted and fixed in a groove formed in the door stop of the door frame of a door or window, ensuring airtightness of the door body. Fitting and fixing the airtight rubber is difficult by hand, especially in winter, because the airtight rubber is a relatively hard material and the material hardens. In addition, airtight rubber cannot be attached evenly when applied manually, which may cause the rubber to lift or peel off. Patent Document 1 describes an invention related to a tool using a roller that applies a groove insert such as adhesive tape to the bottom of the groove while pressing it down.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-270123 Summary of the Invention [Problem to be solved by the invention]
[0004] Airtight rubber is a hollow member. Therefore, when using a roller to fit and fix the airtight rubber in a groove, it is preferable that the shape of the roller is designed so that a pressing force can be applied to the airtight rubber more efficiently. The object of the present invention is to provide a fixing tool that can efficiently apply a pressing force to the airtight rubber to be fitted and fixed in a groove. [Means for solving the problem]
[0005] The fixed tool of the present invention is a fixed tool used when fitting and fixing airtight rubber into a groove portion, and comprises a resin roller, a support shaft that penetrates the roller and supports it so that it can rotate freely, a connection portion connected to the support shaft, and a gripping portion connected to the connection portion, and the roller has a convex portion formed on its outer circumferential surface that is convex in the radial direction. In this configuration, the convex portion of the roller presses the airtight rubber in the first direction around the center of the material shaft of the airtight rubber, so that the pressing force is easily applied to the entire airtight rubber, and therefore the airtight rubber is efficiently pressed in the first direction.
[0006] In the fixed tool of the present invention, it is preferable that the connection portion includes a straight portion extending in a first direction and a bent portion bent in a second direction that intersects the first direction, the support shaft is connected to the connection portion at an end of the bent portion on the second direction side, and the grip portion is connected to the connection portion at an end of the straight portion opposite the bent portion. In this configuration, the roller is attached to the gripper in a cantilever structure, which makes it possible to work with one hand and prevents the fixing tool from coming into contact with the door body or the wall of the building, thereby improving the ease of fitting and fixing the airtight rubber into the groove.
[0007] In the stationary tool of the present invention, it is preferable that a stopper ring for preventing the roller from coming off is attached to the support shaft so as to be located on the second direction side of the roller. With this configuration, when the rollers are fitted and fixed into the grooves of the airtight rubber due to rotation of the rollers, the rollers can be prevented from coming loose, and vibrations caused by the rotation of the rollers, etc. can be suppressed.
[0008] In the fixed tool of the present invention, it is preferable that a recess is formed in the roller in an area including at least the portion of the side surface on the second direction side through which the support shaft passes, and that the end of the support shaft on the second direction side and the anti-pullout ring are located closer to the bottom of the recess than the side surface of the roller. In this configuration, the end of the support shaft and the retaining ring are housed in the recess, which prevents the end of the support shaft from coming into contact with the door close to the fixing tool and damaging the door when the airtite rubber is fitted and fixed in the groove.
[0009] In the stationary tool of the present invention, it is preferable that in a cross section taken along the rotation axis direction of the roller, the ratio of the width of the convex portion to the width of the entire outer circumferential surface of the roller is 0.5 or more and 0.7 or less. In this configuration, the width of the convex portion is dimensioned to match the airtight rubber to be fitted and fixed in the groove, making it easier to fit the airtight rubber into the groove.
[0010] In the stationary tool of the present invention, it is preferable that the length of the straight portion of the connection portion is not less than 50 mm and not more than 100 mm. In this configuration, the operation of fitting and fixing the airtight rubber 20 into the groove portion 30 can be stabilized. [Brief description of the drawings]

[Diagram 2] 5A and 5B are diagrams for explaining the relationship between the roller and the airtight rubber according to the embodiment. [Diagram 3] FIG. 2 is a cross-sectional view showing a structure of a roller of the stationary tool according to the embodiment. [Figure 4] 4 is a cross-sectional view showing the structure of a support shaft and a connection portion of the stationary tool according to the embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Hereinafter, specific embodiments will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals, and duplicated descriptions will be omitted as necessary for clarity of explanation.
[0013] Fig. 1 is a perspective view of a fixed tool 10 according to this embodiment. In Fig. 1, (a) and (b) are perspective views of the fixed tool 10 as viewed from different directions. In the figure, two directions perpendicular to each other are defined as the +x direction and the +y direction. Although not shown in the figure, the direction opposite to the +x direction is defined as the -x direction, and the direction opposite to the +y direction is defined as the -y direction. The +x direction corresponds to the first direction, and the +y direction corresponds to the second direction.
[0014] As shown in the figure, the stationary tool 10 includes a roller 11, a support shaft 12, a connection portion 13, and a gripping portion 14. The roller 11 includes a through hole 111, a protruding portion 112, and a recessed portion 113, and the support shaft 12 includes a retaining ring 121. The connection portion 13 includes a straight portion 131 and a bent portion 132. The details of each portion will be described later.
[0015] The fixing tool 10 is a tool used when fitting and fixing the airtight rubber 20 into the groove portion 30. The groove portion 30 is formed in a portion of the door frame where the door abuts. In the following description, the door includes a so-called hinged door that can be opened and closed by parts such as hinges, a sliding door that opens and closes along a rail formed on the floor portion, and a window.
[0016] The relationship between the roller 11 and the airtight rubber 20 according to this embodiment will be described with reference to Fig. 2. In Fig. 2, (a) shows the state before the airtight rubber 20 is pressed by the roller 11, and (b) shows the state in which the airtight rubber 20 is fitted and fixed in the groove portion 30 by the roller 11. The airtight rubber 20 is pressed in the +x direction by the rotation of the roller 11, and is fitted and fixed in the groove portion 30. The roller 11 is preferably formed of a hard member such as resin in order to press the airtight rubber 20.
[0017] As shown in the figure, the roller 11 has a convex portion 112 formed on the outer circumferential surface thereof, which is convex in the radial direction. In a cross section perpendicular to the material axis direction, the airtight rubber 20 has a hollow center portion. Therefore, when the convex portion 112 of the roller 11 presses the airtight rubber 20 in the +x direction centered on the center portion of the material axis, the pressing force is easily applied to the entire airtight rubber 20. Therefore, the airtight rubber 20 is efficiently pressed in the +x direction and fitted and fixed in the groove portion 30.
[0018] 3 is a cross-sectional view of the roller 11 of the stationary tool 10 according to this embodiment taken along line III-III in FIG. 1(b). As shown in the figure, the support shaft 12 passes through the through hole 111 in the +y direction and rotatably supports the roller 11. A retaining ring 121 for retaining the roller 11 is attached to the support shaft 12 so as to be located on the +y side of the roller 11. Therefore, the roller 11 is prevented from coming off by the retaining ring 121. The retaining ring 121 may be, for example, a C-ring or a washer, but is not limited to these and may be any member capable of preventing the roller 11 from coming off.
[0019] The support shaft 12 is provided with a groove for attaching a retaining ring 121. By providing the retaining ring 121, when the roller 11 rotates and is fitted and fixed into the groove portion 30 of the airtight rubber 20, the roller 11 can be prevented from coming off, and vibrations caused by the rotation of the roller 11 can be suppressed.
[0020] Moreover, w1 shown in the drawing is the width of the entire outer circumferential surface of the roller 11 in a cross section along the rotation axis direction of the roller 11, and w2 is the width of the protrusion 112. The values of the width w1 and the width w2 are preferably values that match the width of the airtight rubber 20 to be fitted and fixed, and for example, the width w1 may be 10 mm and the width w2 may be 6 mm, but are not limited to this.
[0021] As described above, since the airtight rubber 20 is a hollow member, if the width of the convex portion 112 of the roller 11 is set in accordance with the width of the hollow portion of the airtight rubber 20, the airtight rubber 20 can be efficiently fitted and fixed in the groove portion 30. From this viewpoint, the ratio of the width w2 to the width w1 is preferably 0.5 or more and 0.7 or less, and more preferably 0.55 or more and 0.65 or less. By adopting such a ratio of the width w2 to the width w1, the dimensions of the convex portion 112 become the dimensions that match the airtight rubber 20 to be fitted and fixed in the groove portion 30, so that the airtight rubber 20 can be easily fitted and fixed in the groove portion 30.
[0022] Further, the roller 11 has a recess 113 formed in an area including at least a portion of the side surface S on the +y direction side through which the support shaft 12 penetrates. The recess 113 may also be formed on the side surface on the -y direction side of the roller 11. The end 12A on the +y direction side of the support shaft 12 and the retaining ring 121 are located closer to the bottom of the recess 113, i.e., closer to the -y direction side, than the side surface S on the +y direction side of the roller 11. That is, the end 12A of the support shaft 12 and the retaining ring 121 are stored in the recess 113. Therefore, during the operation of fitting and fixing the airtight rubber 20 to the groove portion 30, the end 12A of the support shaft 12 is prevented from contacting the door adjacent to the fixed tool 10 and from damaging the door.
[0023] 4 is a cross-sectional view showing the structure of the support shaft 12 and the connection part 13 of the stationary tool 10 according to this embodiment. The support shaft 12 and the connection part 13 may be made of a metal such as stainless steel, but are not limited to this. Furthermore, the support shaft 12 and the connection part 13 may be integrally formed or may be separate members.
[0024] As shown in the figure, the connection portion 13 includes a straight portion 131 extending in the +x direction and a bent portion 132 bent in the +y direction, which is a direction perpendicular to (intersecting) the +x direction. The connection portion 13 is connected to the support shaft 12 at the end of the bent portion 132 on the +y direction side. With this configuration, the roller 11 is attached to the grip portion 14 by a cantilever structure. This improves the ease of work when fitting and fixing the airtight rubber 20 into the groove portion 30, by enabling work with one hand and preventing the fixing tool 10 from coming into contact with a door body or a wall of a building.
[0025] As shown in the figure, the connection portion 13 is connected to the grip portion 14 at the end of the straight portion 131 opposite the bent portion 132, i.e., the end on the -x direction side. The grip portion 14 may be made of resin, wood, or stainless steel, but is not limited to these. The grip portion 14 may be made of a roughly cylindrical round bar as shown in Fig. 1, but is not limited to this and may have any shape that can be gripped.
[0026] Also, d shown in the figure is the length of the straight portion 131. If the value of the length d of the straight portion 131 is too large, the fixing work of the airtight rubber 20 becomes unstable when the roller 11 rotates. If the value of the length d of the straight portion 131 is too small, it is difficult to perform the work in a narrow area. From this point of view, the length d of the straight portion 131 is preferably 50 mm or more and 100 mm or less, more preferably 60 mm or more and 90 mm or less, and even more preferably 70 mm or more and 80 mm or less. If the length d of the straight portion 131 is as described above, the work of fitting and fixing the airtight rubber 20 to the groove portion 30 using the fixing tool 10 can be stabilized.
[0027] According to the stationary tool 10 described in the above embodiment, the following effects are achieved. (1) The protrusions 112 press the airtight rubber 20 in the +x direction around the center of the material axis, so that the pressing force is easily applied to the entire airtight rubber 20. Therefore, by providing the protrusions 112 on the outer circumferential surface of the roller 11, the airtight rubber 20 is efficiently pressed in the +x direction.
[0028] (2) The roller 11 is attached to the gripping portion 14 in a cantilever structure. This allows the work to be done with one hand and prevents the fixing tool 10 from coming into contact with a door body or a building wall, improving workability when fitting and fixing the airtight rubber 20 into the groove portion 30.
[0029] (3) By providing the anti-slip ring 121 on the support shaft 12, it is possible to prevent the roller 11 from slipping out when the roller 11 rotates to be fitted and fixed into the groove portion 30 of the airtight rubber 20, and it is also possible to suppress vibrations caused by the rotation of the roller 11, etc.
[0030] (4) The end 12A of the support shaft 12 and the retaining ring 121 are housed in the recess 113. Therefore, when the airtight rubber 20 is fitted and fixed in the groove 30, the end 12A of the support shaft 12 can be prevented from contacting the door adjacent to the fixed tool 10, and damage to the door caused by the work using the fixed tool 10 can be suppressed.
[0031] (5) The ratio of the width w2 of the protrusions 112 in a cross section along the rotation axis direction of the roller 11 to the width w1 of the entire outer circumferential surface of the roller 11 in the cross section is 0.5 to 0.7. By adopting such a ratio of the width w2 to the width w1, the dimensions of the protrusions 112 are adjusted to the dimensions of the airtight rubber 20 to be fitted and fixed in the grooves 30, making it easier to fit and fix the airtight rubber 20 in the grooves 30.
[0032] (6) The length d of the straight portion 131 is preferably 50 mm or more and 100 mm or less, more preferably 60 mm or more and 90 mm or less, and even more preferably 70 mm or more and 80 mm or less. By setting the length d of the straight portion 131 as described above, the workability when fitting and fixing the airtight rubber 20 into the groove portion 30 can be improved.
[0033] Although the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to these examples. It is clear that a person skilled in the art in the technical field to which the present invention pertains can come up with various modified or amended examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally fall within the technical scope of the present invention.
