Description

  The present invention relates to a film stopper member used when a film forming an outer surface of a greenhouse is fixed on a house construction material.

  Conventionally, the film forming the outer surface of a greenhouse is attached to a film fixing member for fixing the film on the house construction material forming the skeleton of the greenhouse, and is fixed on the house construction material via the film fixing member. It was.

  This film fixing member is a hook-like body provided with a fixing groove along the longitudinal direction by bending a steel metal plate, and is inserted into the fixing groove by slackening the film. At the same time, the film was clamped between the spring and the side wall of the fixing groove by inserting a spring for film locking meandering with a predetermined swing width from above the film.

  In this way, the film is sandwiched and fixed by the film stopper member and the spring. Therefore, when the fixing groove is formed, the longitudinal side of the bottom wall portion 12 of the fixing groove 11 is formed as shown in FIG. Left and right side walls 13 and 13 are formed by raising the left and right end edges obliquely upward, and when the spring s is inserted into the identification groove 11, the spring s is inclined to the fixing groove 11 and left and right side walls. 13 and 13 are automatically pushed to the bottom wall 2 side so that the pressing force of the spring s is surely transmitted to the left and right side walls 13 and 13 of the fixing groove 11.

  Moreover, the curved edges 16 are formed by bending the ends of the left and right side walls outward at the opening edge of the fixing groove 11, and the film f does not get caught at the opening edge when the film f is inserted into the fixing groove 11. It was configured to be inserted smoothly (see, for example, Patent Document 1).

  However, in the case where the shape of the fixing groove is the shape shown in FIG. 8 described above, a recess is formed at a position where the tip of the curved portion 16 contacts the side wall portion 13, and moisture such as rainwater accumulates in the recess. It was the cause of rust.

  In addition, when the edge of one film stopper member X1 is swaged, and the processed portion is inserted into the fixing groove 11 of the other film stopper member X1, the film stopper member X1 is connected to each other. At the stage of carrying out the process, the curved portion 16 must be crushed so that it can be easily inserted into the fixing groove 11 of the film stopper member X1, which takes time and effort.

  Furthermore, while securing the opening width of the fixing groove 11 so that the spring s can be inserted, the left and right side wall portions 13, 13 of the fixing groove 11 must be inclined so that the inserted spring s does not come out of the fixing groove 11. Therefore, the fixing groove 11 has to be formed shallowly. For this reason, when fixing one film f, there is no problem, but when fixing the second and subsequent films f, one spring s is provided in the fixing groove 11 each time one film f is fixed. Since it had to be inserted inside, the spring s could not be normally inserted inside the shallow fixing groove 11 and a plurality of films f could not be fixed in a superimposed manner.

Therefore, as shown in FIG. 9, the right and left side wall portions 23, 23 of the fixing groove 21 are raised from the middle at a right angle to the bottom wall portion 22 to form the fixing groove 21 deeply, and at the opening edge of the fixing groove 21. The ends of the side wall portions 23, 23 are bent at right angles to the inside to form the retaining portions 24, and the distal ends of the retaining portions 24 are folded inward to form the folding portions 26, whereby the spring s is formed. A film stopper member X2 that can accommodate a plurality of springs s while securing an insertable opening width is also known (see, for example, Patent Document 2).

  However, when the shape of the fixing groove is as shown in FIG. 9, a plurality of springs can be accommodated simultaneously, but the left and right side wall portions of the fixing groove are perpendicular to the bottom wall portion from the middle as described above. Therefore, unlike the film stopper shown in FIG. 8, the spring inserted into the fixing groove is not naturally pushed to the bottom wall side of the fixing groove. Therefore, the spring does not become parallel to the bottom wall portion inside the fixing groove, and as shown in FIG. 9, one end remains inclined to the bottom wall portion side and the other end is inclined to the opening portion side. In some cases, the pressure is not normally transmitted to the left and right side wall portions of the fixing groove, and the film cannot be reliably fixed.

  In addition, if the spring is left obliquely inclined inside the fixing groove, the film is unnaturally pressed against the retaining portion for a long period of time, and there is a high possibility that the film is damaged. When trying to make the spring parallel to the bottom wall, the film is dragged while being sandwiched between the side wall and the spring, and may be damaged.

  Furthermore, when the edges are swaged to connect the film stopper members, the degree of compression in the vertical direction as well as in the horizontal direction with the side walls must be taken into account due to the above-described retaining part and folding part. If the bottom wall portion was wavy and the degree of compression was not increased, the size could not be inserted into the fixing groove of the other film stopper member. Therefore, the internal space of the fixing groove in the swage processing portion becomes narrow, and it becomes difficult to insert one spring.

  Accordingly, in the film stopper member according to claim 1, the film stopper member for fixing the film for forming the greenhouse on the house construction material, the left and right edges forming the long side of the long plate-like bottom wall portion Are formed obliquely upward toward the inside to form left and right side wall portions, and the right and left side wall portions and the bottom wall portion form a fixing groove for clamping the film, and the front ends of the left and right side wall portions. Are folded inward to form a folded portion, and the folded inner surface of the folded portion and the side wall surface that is on the bottom wall side of the folded portion are substantially flush with each other.

  The film stopper member according to claim 2 is a film stopper member for fixing a film for forming a greenhouse on a house construction material, and includes a long plate-like bottom wall portion and a length of the bottom wall portion. A fixing groove for clamping the film is formed by left and right side walls that are obliquely upwardly directed from the left and right end edges, respectively, and at one or both ends of the fixing groove of another film stopper member. An insertable contracted connecting portion is formed, and the bottom wall portion of the contracted connecting portion is substantially planar along the bottom wall portion of another inserted film stopper member, and the left and right side wall portions are formed. , And formed so as to protrude from the upper ends of the left and right side wall portions of the other inserted film stoppers.

  According to a third aspect of the present invention, in the film stopper member, the contracted connecting portion presses the fixing groove from the left and right directions while the bottom wall portion is pressed and held from above to extend the left and right side walls upward.

  In the film stopper member according to claim 4, the upper end corners of the left and right side wall portions are chamfered in the reduced connection portion.

  Further, in the film stopper member according to claim 5, the front ends of the left and right side wall portions are folded back inward to form a folded portion, and the folded inner surface of the folded portion and the bottom wall portion side of the folded portion are arranged. The side wall portion surface formed is substantially flush.

  In the film stopper member according to claim 6, the left and right side wall portions are raised in a curved shape at an inclination angle of about 45 degrees with respect to the bottom wall portion, and extended from the middle at an inclination angle of about 60 degrees. .

  According to this invention of Claim 1, it is a film stop member which fixes the film for forming a greenhouse on a house construction material, Comprising: The left-right edge which makes the longitudinal side of a long-plate shaped bottom wall part The left and right side walls are formed to rise obliquely upward toward the inside, and the fixing grooves for clamping the film are formed by the left and right side walls and the bottom wall, and the tips of the left and right side walls are formed. Since the folded portion is formed by folding each inside, and the folded inner surface of the folded portion and the side wall portion surface that forms the bottom wall portion side from the folded portion are substantially flush with each other, film fixing work Sometimes the film does not get damaged by being caught in the folding part. Therefore, it is not necessary to perform the film fixing work while paying attention not to catch the film, and the work efficiency can be improved. In addition, it is possible to prevent generation of useless films that are damaged and cannot be used. In addition, since the folding part is provided inside the fixing groove, it is difficult for moisture to collect at the contact part between the side wall part of the fixing groove and the tip of the folding part compared to the case where it is folded back to the outside of the fixing groove, thereby suppressing the generation of rust. be able to. Furthermore, since the front ends of the left and right side wall portions are not bent, but are turned back into fold portions, the front ends of the left and right side wall portions are not swelled, and the fold portions are crushed as pre-processing when swaging is performed. There is no need. Therefore, swaging can be performed without taking time and effort.

  According to this invention of Claim 2, it is a film stop member which fixes the film for forming a greenhouse on a house construction material, Comprising: A long-plate-shaped bottom wall part and the longitudinal side of the bottom wall part A fixing groove for clamping the film is formed by left and right side wall portions that rise obliquely upward inward from the left and right edge edges, and is inserted into a fixing groove of another film stopper member at one or both ends. Forming a possible contracted connecting portion, and the bottom wall portion of the contracted connecting portion is substantially planar so as to follow the bottom wall portion of the other inserted film stopper member, and the left and right side wall portions, Since it is formed so as to protrude from the upper ends of the left and right side wall portions of the other inserted film stopper members, the depth of the fixing groove can be ensured more reliably even in the contracted connecting portion, and a spring for film locking can be provided. Fixing of compacted joints It can be inserted a plurality of stably on. For this reason, a plurality of films can be reliably fixed even in the contracted connecting portion.

  According to the third aspect of the present invention, since the contracted connecting portion presses the fixing groove from the left and right directions while the bottom wall portion is pressed and held from above, the left and right side walls are extended upward. The compact connecting portion can be formed without trouble in processing, and the manufacturing cost of the film stopper member can be suppressed even if the compact connecting portion is provided.

  According to the fourth aspect of the present invention, since the upper end corners of the left and right side wall portions are chamfered in the reduced size connecting portion, the reduced size connecting portion is inserted when inserted into another film stopper member. Even if the left and right side wall portions of the contracted connecting portion protrude from the upper ends of the left and right side wall portions of the film stopper member, the film is not caught and damaged at the upper end corner portions of the protruding left and right side wall portions, and the film is safely fixed. be able to.

  According to this invention of Claim 5, the front-end | tip of the said right-and-left side wall part is turned inward, respectively, and a folding part is formed, and also the folding | turning inner surface of this folding part and the bottom wall part side are made | formed from the said folding part. Since the surface of the side wall portion is substantially flush, the film is not caught and damaged by the folding portion during the film fixing operation. Therefore, it is not necessary to perform the film fixing work while paying attention not to catch the film, and the work efficiency can be improved. In addition, it is possible to prevent generation of useless films that are damaged and cannot be used. In addition, since the folding part is provided inside the fixing groove, it is difficult for moisture to collect at the contact part between the side wall part of the fixing groove and the tip of the folding part compared to the case where it is folded back to the outside of the fixing groove, thereby suppressing the generation of rust. be able to. Furthermore, since the front ends of the left and right side wall portions are not bent, but are turned back into fold portions, the front ends of the left and right side wall portions are not swelled, and the fold portions are crushed as pre-processing when swaging is performed. There is no need. Therefore, swaging can be performed without taking time and effort.

  According to the sixth aspect of the present invention, the left and right side wall portions are raised in a curved shape at an inclination angle of about 45 degrees with respect to the bottom wall portion, and are extended at an inclination angle of about 60 degrees from the middle. In the fixing groove, it is possible to secure a depth capable of accommodating a plurality of springs while ensuring an opening width in which a film locking spring can be easily inserted. Can be fixed more reliably.

  The film stopper member according to the present invention is a film stopper member for fixing the film on the house construction material when the film is stretched to form a greenhouse, and the length of the long plate-like bottom wall portion The left and right end edges rise obliquely upward toward the inside to form left and right side walls, and the right and left side walls and the bottom wall form a fixing groove for clamping the film. . In addition, the ends of the left and right side walls of the fixing groove whose cross-sectional shape is gradually narrowed from the bottom wall to the opening are folded inward to form a folded portion, and the folded inner surface of the folded portion And the side wall surface that forms the bottom wall portion side with respect to the folding portion are substantially flush with each other.

  As described above, the inner surface of the folded portion is formed so that the inner surface of the folded portion is flush with the surface of the side wall portion inside the fixing groove, so that the film inserted into the fixing groove is inserted into the meandering spring and fixed. When performing a film fixing operation for fixing the film by sandwiching it with the side wall portion of the groove, the film is not caught and damaged by the folding portion. Therefore, it is not necessary to perform the film fixing operation while paying attention so that the film does not get caught, so that the work efficiency can be improved, and it is possible to prevent the useless film that cannot be used due to damage.

  In addition, since the folding portion is provided inside the fixing groove, the contact portion between the leading end of the folding portion and the side wall portion is exposed to wind and rain compared to the case where the front end of the side wall portion is folded back to the outside of the fixing groove. It is difficult, and moisture, such as rain water, does not collect easily in the said contact part. Therefore, generation | occurrence | production of the rust resulting from the water | moisture content collected in the contact part can be suppressed.

  In particular, when the film fixing member is mounted on its side so that the fixing groove extends in the horizontal direction, the opening of the fixing groove is inclined obliquely upward along the shape of the greenhouse. When attached to a state or a vertically standing state facing sideways, it was easy for water to collect at the contact portion between the folded portion and the side wall portion. Therefore, rust can be effectively prevented by providing the folding portion inside the fixing groove as described above so that the contact portion does not appear on the outer surface of the film stopper member.

  In addition, if the folding part is brought into close contact with the side wall part so that there is no gap between the folding part and the side wall part, it is possible to prevent moisture such as rainwater from accumulating between the folding part and the side wall part. The generation of rust can be further suppressed.

  In addition, since the ends of the left and right side wall portions are bent rather than curved to form a folded portion, one end portion or both end portions of the film stopper member are swaged, and the processed portion is used as a contracted connecting portion to fix other film stoppers. Even when a plurality of film stoppers are connected by inserting them into one end of the member, it is not necessary to dare to crush the folding part as a pre-processing of the swaging process, and the swaging can be efficiently performed without taking time and effort. Processing can be performed.

  Moreover, the film stopper member according to the present invention has a configuration in which the left and right side wall portions face each other, but does not have a configuration facing the bottom wall portion. Even if compression in the vertical direction is not performed, the film stopper member that has been swaged can be inserted into the other film stopper member. Accordingly, when the swaging is performed, the internal space of the fixing groove can be left wide, and a plurality of springs can be inserted into the swaging portion.

  In particular, as described above, in the case of forming a reduced connection portion that can be inserted into the fixing groove of another film stop member at one or both ends of the film stop member, the bottom wall portion in the same reduced connection portion is inserted. It is desirable to form a substantially flat shape along the bottom wall portion of the other film stopper member, and to form the left and right side wall portions so as to protrude from the upper ends of the left and right side wall portions of the inserted other film stopper member. With this configuration, the depth of the fixing groove in the contracted connecting portion can be ensured more reliably, and a plurality of springs for film locking can be stably inserted into the fixing groove of the contracted connecting portion. . For this reason, a plurality of films can be reliably fixed even in the contracted connecting portion.

  The compacted connecting portion having the above-described configuration can be formed by pressing the fixing groove from the left and right directions and extending the left and right side walls upward while pressing and holding the bottom wall from above when performing swaging. . That is, by applying pressure only to the fixing groove from the left and right when performing the swaging process, the vertical width of the compacted connecting portion is prevented from being shorter than that before the swaging process, and the bottom wall portion where the pressure is applied is It escapes to the left and right side wall parts, and shortens the left and right width of the contracted connecting part while keeping the shape of the bottom wall part flat.

  By forming the reduced-sized connecting portion in this way, the reduced-sized connecting portion can be formed with a simple process and without trouble, and even if the reduced-sized connecting portion is provided, the manufacturing cost of the film stopper member can be reduced. be able to. Further, if the reduced-shaped connecting portion formed in this way is inserted into the end of another film stopper member, the reduced-shaped connecting portion is lifted by the thickness of the bottom wall portion of the inserted other film stopper member. The left and right side wall portions in the contracted connecting portion will protrude from the upper ends of the left and right side wall portions of the other inserted film stopper member, while the bottom wall portion in the contracted connecting portion is the same as the other film stopper member inserted. It will be along the bottom wall.

  It is desirable to chamfer the upper corners of the left and right side wall portions in the contracted connecting portion. With this configuration, the film connecting member is connected by inserting the contracted connecting portion into another film stopping member. Sometimes, even if the left and right side wall portions of the reduced shape connecting portion protrude from the upper ends of the left and right side wall portions of the film stopper member into which the reduced shape connecting portion is inserted, the film is caught and damaged at the upper end corner portions of the protruding left and right side wall portions. This makes it possible to fix the film safely.

  Further, it is desirable that the film stopper member rises in a curved shape with an inclination angle of about 45 degrees with respect to the bottom wall section on the left and right side walls, and extends at an inclination angle of about 60 degrees from the middle. By setting the inclination angle of the left and right side wall portions to the bottom wall portion to be approximately 60 degrees or less, the spring inserted into the fixing groove is automatically pushed to the bottom wall portion side by the inclined surface of the side wall portion, so that the fixing groove Inside the spring can be placed horizontally with the bottom wall. Accordingly, the pressing force of the spring can be applied uniformly to the left and right side wall portions, so that the film can be reliably fixed.

  In particular, the inclination angle of the side wall portion is changed between the side adjacent to the bottom wall portion and the side away from the bottom wall portion, and the inclination angle of the side adjacent to the bottom wall portion is changed from the side away from the bottom wall portion. If the inclination angle is about 45 degrees, which is smaller than the inclination angle, the spring is surely pushed toward the bottom wall, and the spring and the film can be prevented from coming off from the fixing groove.

  In addition, if the inclination angle on the side away from the bottom wall portion is set to approximately 60 degrees, which is larger than the inclination angle on the side adjacent to the bottom wall portion, the opening width of the fixing groove is secured so that the spring can be easily inserted. However, the depth of the fixing groove can be increased so that a plurality of springs can be accommodated, and a plurality of films can be fixed simultaneously with the film stopper. That is, a spring that could not be accommodated inside the side wall portion inclined at about 45 degrees is accommodated inside the side wall portion inclined at about 60 degrees, and a plurality of springs can be simultaneously accommodated inside the fixing groove. it can.

  Moreover, each spring accommodated can be automatically pushed to the bottom wall portion side by the inclined surface of the side wall portion and can be arranged horizontally with respect to the bottom wall portion, so that the pressing force of each spring is effectively reduced. By acting on the film, a plurality of films can be reliably fixed.

  In particular, in this embodiment, the folding part is also inclined approximately 60 degrees along the side wall part, and the folding part is not raised perpendicularly to the bottom wall part. Therefore, the film can be stably fixed by automatically pushing the spring toward the bottom wall portion on the inclined surface even in the folding portion.

  The film stopper member is formed so that the ratio of the depth, opening width, and maximum width in the fixing groove is 129 to 131: 175 to 185: 314 to 316, more preferably 130: 180: 315. It is desirable that the maximum width of the fixing groove can be made as small as possible while ensuring the opening width into which the spring can be inserted and the depth into which the plurality of springs can be inserted. The enlargement of the film stopper can be prevented.

  Note that the above-described film stopper member can be formed by bending a metal plate made of steel or the like, or extruding a metal such as aluminum.

  Hereinafter, specific embodiments of the film stopper member according to the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a front view of a film stopper member as a first embodiment of the present invention, FIG. 2 is a perspective view showing a use state of the film stopper member A1, and FIG. 3 is a cross-sectional view taken along the line II of FIG. .

  As shown in FIG. 2, the film stopper member A1 is a bowl-shaped body provided with fixing grooves 1 for clamping the film f along the longitudinal direction. In the present embodiment, a long plate-like bottom is formed using a metal plate. As shown in FIG. 1, the wall portion 2 is formed and the left and right end edges forming the longitudinal side of the bottom wall portion 2 are raised obliquely upward toward the inside to form left and right side wall portions 3, 3. A fixing groove 1 that is narrower toward the opening 4 side is formed between the left and right side wall portions 3 and 3 and the bottom wall portion 2.

  When the left and right side wall portions 3 and 3 are raised, first, the metal plate is raised in a curved shape at an inclination angle θ1 of about 45 degrees with respect to the bottom wall portion 2 to form a gentle slope portion 3a. A steep slope portion 3b is formed by raising a metal plate continuous from the slope portion 3a at an inclination angle θ2 of about 60 degrees with respect to the bottom wall portion 2.

  In this way, by changing the rising angle of the left and right side wall portions 3 and 3 in the middle to form the gentle slope portion 3a and the steep slope portion 3b, when the number of films f to be fixed is one, the gentle slope The film s can be reliably fixed by accommodating the spring s in the inner part of the portion 3a. Then, even if there are a plurality of films f to be fixed, the springs s that cannot be accommodated in the inner portion of the gentle slope portion 3a are accommodated in the inner portion of the steep slope portion 3b, so that the plurality of films f can be satisfactorily fixed. Can do.

  In the present embodiment, when the left and right side wall portions 3 and 3 are raised from the left and right ends of the bottom wall portion 2 as described above, the bottom wall portion 2 is formed between the left and right side wall portions 3 and 3. The depth L1 of the fixing groove 1 is 13 ± 0.1 mm, the opening width L2 is 18 ± 0.5 mm, and the maximum width L3 is 31.5 ± 0.1 mm. As described above, the ratio of the depth L1, the opening width L2, and the maximum width L3 of the fixing groove 1 is approximately 130: 180: 315 (that is, approximately 26:36:63). The maximum width L3 can be made as small as possible while securing the opening width L2 into which s can be inserted and the depth L1 into which multiple springs s can be accommodated. Can be prevented.

  The leading ends of the left and right side wall portions 3, 3 raised as described above are folded portions 6 that are folded inside the fixing groove 1 and overlap the side wall portions 3, and the opening edge portion of the fixing groove 1 is the folding portion 6. Doubled from the side wall 3. Then, the side wall 3 that overlaps the folding part 6 protrudes to the outside by the same width as the thickness of the metal plate forming the folding part 6, that is, to the side opposite to the fixing groove 1. The surface is substantially flush with the surface of the side wall 3 on the bottom wall 2 side of the folding part 6. As described above, the inner surface of the folding portion 6 and the surface of the side wall portion 3 on the bottom wall portion 2 side of the folding portion 6 are substantially flush with each other in the fixing groove 1. It is not necessary to perform film fixing work while paying attention to prevent the film from being caught, and it is possible to improve the work efficiency of the film fixing work and to prevent the generation of useless film that is damaged and cannot be used. it can.

  Moreover, in this embodiment, as shown in FIG. 2, the edge part of the film | membrane stop member A1 which consists of the said structure is swaged as needed, and it is set as the compression connection part 8, and the compression connection part 8 is swaged. A plurality of film stopper members A1 can be appropriately connected by slidingly inserting them into the end portions of the film stopper members A1 that are not provided. In particular, in the present embodiment, the end of the film stopper A1 that becomes the contracted connecting portion 8 is pressed from four directions during swaging, and the vertical and horizontal widths of the contracted connecting portion 8 are not swaged. The width is made shorter than the vertical width and the horizontal width of the main body portion 7 of A1. As a result, when the contracted connecting portion 8 of the film stopper member A1 that has been swaged is slid into the end of the film stopper member A1 that has not been subjected to the swaging process, the reduced connecting portion is inserted into the fixing groove 1 of the film stopper member A1. 8 will be completely accommodated.

  In this embodiment, the metal plate is bent to form the film stopper member A1 having the above-described configuration. However, the present invention is not limited to this, and the film stopper member A1 having the same configuration can be formed by extrusion.

  When the film f is attached to the film fixing member A1 having the above configuration, as shown in FIG. 2, the film f is inserted into the fixing groove 1 and then the width of the fixing groove 1 is adjusted from above the film f. A dedicated spring s meandering with a predetermined swing width is inserted, and the film f is clamped by the spring s and the left and right side wall portions 3 and 3 of the fixing groove 1 so that the film f does not come off from the film stopper A1. To. When a plurality of films f are simultaneously attached to the film fixing member A1, the above-described film fixing operation is repeated every time the film f is fixed, and the same number of springs s as the number of films f to be fixed are fixed. Insert into groove 1.

  FIG. 3 shows a state in which the springs s are accommodated in the places where the film stoppers A1 are connected to fix the three films f. Since the film stopper member A1 of the present embodiment can leave a large internal space of the fixing groove 1 even if swaging is performed as described above, a plurality of springs s are also provided at the connecting portions of the film stopper members A1. By inserting, a plurality of films f can be attached simultaneously. In addition, the springs s inserted into the fixing groove 1 can be pressed to the bottom wall 2 side by the inclined surfaces of the left and right side wall portions 3, 3, respectively, so that the springs s can be automatically arranged horizontally with the bottom wall 2. . Accordingly, the pressing force of the spring s can be efficiently applied to the film stopper member A1, and the film f can be securely held between the spring s and the film stopper member A1.

(Second Embodiment)
4 is a perspective view showing a connection state of the film stopper member A2 as a second embodiment of the present invention, FIG. 5 is a side view showing a connection state of the film stopper member A2, and FIG. 6 is a use of the film stopper member A2. It is sectional drawing which shows a state.

  The film stopper member A2 of the present embodiment is different from the film stopper member A1 of the first embodiment in the configuration of the contracted connecting portion 8, and the bottom wall portion 2 at the end of the film stopper member A2 during swaging. Is pressed and held from above and the fixing groove 1 is pressed from the left and right directions to extend the left and right side wall portions 3 and 3 so that the bottom extends in the inner direction of the fixing groove 1 as when pressure is applied from all directions. The wall portion 2 is prevented from being lifted, and a substantially planar bottom wall portion 2 is formed as shown in FIGS. As a result, when the contracted connecting portion 8 of the other film stopper member A2 that has been swaged is slid into the end of one film stopper member A2 that has not been subjected to swaging, the bottom wall portion 2 of the contracted connecting portion 8 is inserted. The whole is along the bottom wall portion 2 of the other film stopper member A2, and the entire bottom wall portion 2 of the contracted connecting portion 8 can be brought into contact with the bottom wall portion 2 of the other film stopper member A2.

  In addition, as described above, by pressing the fixing groove 1 only from the left and right directions to form the contracted connecting portion 8, only the left and right width is shortened compared to the main body portion 7 of the film stopper member A2 that has not been swaged. It is formed as follows. That is, even in the contracted connecting portion 8, the vertical width does not become shorter than the vertical width of the main body portion 7 that is not swaged. As a result, when the compression coupling portion 8 of the film stopper member A2 that has been swaged is slid into the end of the film stopper member A2 that has not been swaged, the compression connection is made inside the fixing groove 1 of the film stopper member A2. The upper end portions of the left and right side wall portions 3 and 3 of the reduced size connecting portion 8 are not fully accommodated and the upper ends of the left and right side wall portions 3 and 3 of the other film stoppers A2 into which the reduced size connecting portion 8 is slid. It will protrude.

  Further, in the present embodiment, the upper corners 9 of the left and right side wall portions 3 and 3 of the reduced-shape connecting portion 8 are chamfered, and as described above, the reduced-shape connecting portion 8 of one film stopper member A2 is connected to the other.
