However, the invention disclosed in Patent Document 1 has a problem that molding is difficult. The reason why molding is difficult is that the engaging piece and the finger hook piece are provided. The engagement piece and the finger hook piece are provided because they are pushed to facilitate attachment and detachment.

The present invention solves the above-mentioned problems. An object of the present invention is to provide a cushioning material for shutter slats that is easy to install and remove and can be easily molded.

The cushioning material for shutter slats of the present invention will be described with reference to the drawings. It should be noted that the reference numerals in the drawings are used in this column for the purpose of assisting the understanding of the contents of the invention, and are not intended to limit the contents to the illustrated range.

In order to solve the above-mentioned problems, according to a certain aspect of the present invention, the shutter slat cushioning material 30 is attached to the slat connecting portions 22 and 24. The slat connecting portions 22 and 24 are portions of a predetermined shutter 10 for connecting adjacent pairs of slat 20 to each other. The slat connecting portions 22 and 24 are also portions protruding from one surface of the shutter 10. The shutter 10 comprises at least three slats 20. The shutter slats cushioning material 30 includes one connecting cover portion 40, the other connecting cover portion 42, and a cover connecting portion 44. On the other hand, the connecting cover portion 40 is for covering the one connecting portion 22. On the other hand, the connecting portion 22 is one of a pair of adjacent slat connecting portions 22 and 24 among the plurality of slat connecting portions 22 and 24. The other connecting cover portion 42 is for covering the other connecting portion 24. The other connecting portion 24 is the other of a pair of adjacent slat connecting portions 22 and 24 among the plurality of slat connecting portions 22 and 24. The cover connecting portion 44 connects the one connecting cover portion 40 and the other connecting cover portion 42. On the other hand, the connecting cover portion 40 has a hooking portion 60 on the one hand and a concave forming portion 62 on the other hand. On the other hand, the hooking portion 60 is for being hooked on the connecting portion 22 on the other hand. On the other hand, the concave forming portion 62 is connected to the hooking portion 60. On the other hand, the concave forming portion 62 forms a concave portion 70 for fitting the one connecting portion 22. The other connecting cover portion 42 has the other hooking portion 80 and the other concave forming portion 82. The other hooking portion 80 is for being hooked on the other connecting portion 24. The other concave forming portion 82 is connected to the other hooking portion 80. The concave forming portion 82 forms a concave portion 90 for fitting the other connecting portion 24. The cover connecting portion 44 connects the concave forming portion 62 on the one hand and the hooking portion 80 on the other side.

The other hooking portion 80 is hooked on the other connecting portion 24, and the recess formed by the other concave forming portion 82 fits into the other connecting portion 24, so that the attachment of the other connecting cover portion 42 to the other connecting portion 24 is completed. .. At the same time that the attachment of the other connecting cover portion 42 to the other connecting portion 24 is completed, the positioning of the one connecting cover portion 40 with respect to the predetermined shutter 10 is completed. This is because the cover connecting portion 44 connects the one-sided concave forming portion 62 and the other hooking portion 80. In the state where the positioning is completed, the one-side hooking portion 60 is hooked on the one-sided connecting portion 22, and the concave portion formed by the one-sided concave forming portion 62 fits into the one-sided connecting portion 22, so that the one-sided connecting cover to the one-sided connecting portion 22 is covered. The installation of the part 40 is completed. By completing the positioning of the one connecting cover portion 40 at the same time as the mounting of the other connecting cover portion 42 is completed, the mounting becomes easier than in the case where the positioning is required again after the mounting of the other connecting cover portion 42 is completed. .. When removing the cushioning material 30 for the shutter slats, it is possible to apply a force to the other connecting cover portion 42 via the cover connecting portion 44 after the one connecting cover portion 40 is removed. Since a force can be applied to the other connecting cover portion 42 via the cover connecting portion 44, when it is necessary to apply a force to the other connecting cover portion 42 itself in order to remove the other connecting cover portion 42 from the other connecting portion 24. By comparison, the other connecting cover portion 42 can be easily removed from the other connecting portion 24. Since the cover connecting portion 44 is provided, the cushioning material for the shutter slats according to a certain aspect of the present invention is compared with the case where the engaging piece and the finger hook piece are individually provided on the one connecting cover portion 40 and the other connecting cover portion 42. The shape of 30 is simple. As a result, it is possible to provide a cushioning material 30 for shutter slats that is easy to attach and detach and can be easily molded.

Further, the cover connecting portion 44 described above has the facing portion 100 and the other side end portion 104 . The facing portion 100 is arranged so as to face the slats 20 at a position close to the other hooking portion 80 or higher. The slat 20 is a slat 20 arranged so as to be sandwiched between the one connecting portion 22 and the other connecting portion 24 in the following cases. In that case, the one hooking portion 60 is caught on the one connecting portion 22, and the other hooking portion 80 is caught on the other connecting portion 24. The other side end portion 104 is connected to the other end of the facing portion 100 on the other side of the connecting cover portion 42 and the other hook portion 80.

The facing portion 100 is arranged so as to face the slats 20 at a position close to the other hooking portion 80 or higher, and the other side end portion 104 is connected to the other end of the facing portion 100 on the other connecting cover portion 42 side and the other hooking portion 80. As a result, when a force that pushes the other end portion 104 via the facing portion 100 is applied, the force acts in a direction that pushes the other hooking portion 80 against the other connecting portion 24. As a result, it is possible to provide the cushioning material 30 for shutter slats, which is harder to come off than in the case where no such force acts.

Further , the above-mentioned facing portion 100 is bent so as to project in the protruding direction of the slat connecting portions 22 and 24 .

When the facing portion 100 is bent so as to project in the projecting direction of the slat connecting portions 22 and 24, the distance between the one connecting cover portion 40 and the other connecting cover portion 42 may be wider than in the case where the facing portion 100 is straight. The cushioning material 30 for shutter slats can be easily expanded and contracted in the narrowing direction. If the expansion and contraction are easy, the attachment of the one connecting cover portion 40 and the other connecting cover portion 42 to the one connecting portion 22 and the other connecting portion 24 becomes easier than in the case where the expansion and contraction are not easy. Moreover, the facing portion 100 is arranged so as to face the slats 20 at a position close to the other hooking portion 80 or higher. As a result, the possibility that the shutter slat cushioning material 30 will come off from the slat connecting portions 22 and 24 due to the effect of expansion and contraction of the facing portion 100 is lower than when the other hooking portion 80 is closer to the slat 20 than the facing portion 100. .. As a result, it is possible to provide the cushioning material 30 for shutter slats that is easy to install and does not easily come off.

Further, it is desirable that the one-sided connecting cover portion 40 described above further has a one-sided protruding portion 64. On the other hand, the protruding portion 64 is connected to the hooking portion 60. On the other hand, the protruding portion 64 projects to the back side of the one-sided connecting cover portion 40 when viewed from the recess 70 for fitting the one-sided connecting portion 22.

On the other hand, the protruding portion 64 projects to the back side of the one-sided connecting cover portion 40 when viewed from the recess for fitting the one-sided connecting portion 22. On the other hand, the protruding portion 64 is connected to the hooking portion 60. On the other hand, the hooking portion 60 is connected to the concave forming portion 62. As a result, when a force is applied to the one-sided protrusion 64, the force can be applied to the one-sided hooking portion 60 by this principle. On the other hand, if a force can be applied to the hooking portion 60, it becomes easier to remove the one-sided connecting cover portion 40 from the one-sided connecting portion 22 as compared with the case where it cannot be applied. As a result, it is possible to provide the cushioning material 30 for shutter slats that can be easily removed.

The cushioning material for shutter slats according to the present invention is easy to attach and detach, and can be easily molded.

[Installation procedure for cushioning material for shutter slats]
FIG. 4 is a first diagram showing an attachment procedure of the shutter slats cushioning material 30 according to the present embodiment. FIG. 5 is a second diagram showing an attachment procedure of the cushioning material 30 for shutter slats according to the present embodiment. The procedure for attaching the shutter slat cushioning material 30 to the slat connecting portions 22 and 24 according to the present embodiment will be described with reference to FIGS. 1, 4 and 5.

First, a person who intends to attach the shutter slat cushioning material 30 to the slat connecting portions 22 and 24, that is, an operator brings the other guiding portion 84 of the shutter slat cushioning material 30 into contact with the other connecting portion 24. When the other guiding portion 84 comes into contact with the other connecting portion 24, the operator slides the other guiding portion 84 along the surface of the other connecting portion 24. As a result, the recess 90 formed by the other concave forming portion 82 faces the other connecting portion 24. The operator fits the other concave forming portion 82 into the other connecting portion 24. When fitted to the other connecting portion 24, the other connecting cover portion 42 is once elastically deformed. As a result, the gap between the other hooking portion 80 and the other concave forming portion 82 is once widened. When the other connecting cover portion 42 is fitted into the other connecting portion 24, the shutter slat cushioning material 30 can rotate along the circumference of the other connecting portion 24. Utilizing this, the operator brings the one-sided connecting cover portion 40 of the shutter slats cushioning material 30 closer to the one-sided connecting portion 22.

In the case of the present embodiment, when the one-sided connecting cover portion 40 approaches the one-sided connecting portion 22, the one-hooking portion 60 of the one-sided connecting cover portion 40 comes into contact with the one-sided connecting portion 22. On the other hand, when the hooking portion 60 comes into contact with the connecting portion 22, the operator tilts the protruding portion 64 with a finger. As a result, the concave forming portion 62 is once elastically deformed so that the opening of the concave portion 70 is opened. Along with this, each part of the cushioning material 30 for shutter slats is also elastically deformed. When the opening is opened, the operator inserts the one-sided hooking portion 60 into the base of the one-sided connecting portion 22. After the insertion, the operator releases his finger from the protrusion 64.

On the other hand, when the finger is separated from the protruding portion 64, the elastically deformed portion of the shutter slats cushioning material 30 tries to return to the original shape. However, the movement to return to the original shape of the portion is hindered by any of the slats 20 and the slats connecting portions 22 and 24. As a result, the length of the cover connecting portion 44 in the direction from one to the other between the slat connecting portions 22 and 24 is longer than the original length. On the other hand, the connecting cover portion 40 is hooked on the connecting portion 22. The other connecting cover portion 42 is hooked on the other connecting portion 24. On the other hand, the concave forming portion 62 and the other concave forming portion 82 sandwich the slats 20 via the one connecting portion 22 and the other connecting portion 24. As a result, the shutter slat cushioning material 30 is attached to the slat connecting portions 22 and 24. At this time, that is, when the one hooking portion 60 is hooked on the one connecting portion 22 and the other hooking portion 80 is hooked on the other connecting portion 24, the facing portion 100 faces the slat 20 at a position close to the other hooking portion 80 or more. Will be arranged to do so. The slat 20 is a slat 20 arranged so as to be sandwiched between one connecting portion 22 and the other connecting portion 24. The curved surface formed by the facing portion 100 is arranged so as to project in the protruding direction of the slat connecting portions 22 and 24. As a result, the facing portion 100, which was deformed when the shutter slat cushioning material 30 was elastically deformed so as to open the opening of the recess 70 formed by the concave forming portion 62, tends to return to the original shape. Since it tries to return to the original state, the facing portion 100 applies a force in the direction of attracting each other to the one connecting cover portion 40 and the other connecting cover portion 42.

When one shutter slat cushioning material 30 is attached to the slat connecting portions 22 and 24, the operator attaches the other shutter slat cushioning material 30 to the other slat connecting portions 22 and 24 by the same procedure.

[Procedure for removing the cushioning material for shutter slats]
The operator tilts one protruding portion 64 of the shutter slat cushioning material 30 attached to the slat connecting portions 22 and 24 of the slat 20 with a finger. As a result, the concave forming portion 62 is once elastically deformed so that the opening of the concave portion 70 is opened. When the opening is opened, the operator removes the one-sided hooking portion 60 from the one-sided connecting portion 22.

On the other hand, when the hooking portion 60 is disengaged from the one connecting portion 22, the shutter slat cushioning material 30 can be tilted about the other connecting portion 24. When the shutter slat cushioning material 30 is tilted, the operator removes the other connecting cover portion 42 of the shutter slat cushioning material 30 from the other connecting portion 24. As a result, the shutter slat cushioning material 30 is detached from the slat connecting portions 22 and 24.

[Explanation of usage]
The method of using the shutter 10 to which the cushioning material 30 for the shutter slats is attached is the same as that of a well-known shutter. When the shutter 10 is wound up, the shutter slat cushioning material 30 attached to the slat connecting portions 22 and 24 of a certain slat 20 prevents the slat 20 from rubbing against another slat 20. As a result, the occurrence of wear in those slats 20 is suppressed.

[Explanation of effect]
As described above, the cushioning material 30 for shutter slats according to the present embodiment prevents a certain slat 20 provided in the shutter 10 from rubbing against another slat 20.

The shutter slats cushioning material 30 according to the present embodiment is easy to attach and detach. Moreover, the shutter slat cushioning material 30 according to the present embodiment has a simpler shape than the conventional shutter slat cushioning material described below. The shutter slats cushioning material has a protrusion used for attachment and a protrusion used for removal. The positions of those protrusions are different. Since the shape is simpler than that of the conventional cushioning material for shutter slats described above, the cushioning material 30 for shutter slats according to the present embodiment can be easily molded as compared with the cushioning material for conventional shutter slats described above.

In the shutter slat cushioning material 30 according to the present embodiment, when a force for pushing the other side end portion 104 is applied through the facing portion 100, the force acts in the direction of pushing the other hooking portion 80 against the other connecting portion 24. As a result, the shutter slat cushioning material 30 according to the present embodiment is less likely to come off than in the case where no such force acts.

When the shutter slat cushioning material 30 according to the present embodiment is attached to the slat connecting portions 22 and 24 of a predetermined shutter 10, the cover connecting portion 44 is stretched by elastic deformation. Since the cover connecting portion 44 is stretched due to elastic deformation, the shutter slat cushioning material 30 according to the present embodiment is firmly attached to the slat connecting portions 22 and 24 as compared with the case where the cover connecting portion 44 is not stretched.

In the shutter slats cushioning material 30 according to the present embodiment, when a force is applied to the one-side protruding portion 64, a force can be applied to the one-sided hooking portion 60 by this principle. On the other hand, if a force can be applied to the hooking portion 60, it becomes easier to remove the one-sided connecting cover portion 40 from the one-sided connecting portion 22 as compared with the case where it cannot be applied.

[Explanation of modified example]
The cushioning material for shutter slats described above is exemplified in order to embody the technical idea of the present invention. The shape, structure, arrangement, etc. of each member are not limited to those of these embodiments. The shape, structure, and arrangement of each member can be changed in various ways.
