Hereinafter, embodiments of the present invention will be described based on the drawings. The same symbols are assigned to the same parts (or components), and their names and functions are also the same. Therefore, detailed descriptions thereof and the like are not repeated.

The pressure-fixed telescopic rod fall prevention member 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3 .

The press-fixed telescopic rod fall prevention member 1 is made of synthetic resin. The press-fixed telescopic rod fall prevention member 1 may be made of a material other than synthetic resin, such as synthetic rubber or metal. The press-fixed telescopic rod fall prevention member 1 is formed into a shape having the following parts: a bottom plate part 2 and an annular region restricting part (hereinafter referred to as the restricting part) integrally provided on the bottom plate part 2 )3. The bottom plate portion 2 is a square plate portion here, and as shown in FIG. Although this specific length L is about 1 mm to 2 mm, for example, it may be 0 mm. In the front view of FIG. 1( b ), the restricting portion 3 is a perfect circle, and the center of the bottom plate portion 2 is the same as the center of the restricting portion 3 . In addition, the region outside the restricting portion 3 may be a resin member portion of the bottom plate portion 2 that is not provided with a protruding region and has a thick wall. In this case, the resin member portion may have various shapes.

As shown in FIG. 2 , the press-fixed telescopic rod fall prevention member 1 is arranged between an end E of the telescopic rod R and a wall surface W that is an installation portion where the telescopic rod R is provided. In this specification, the so-called telescopic rod is a rod whose length can be adjusted, and refers to a rod that is fixed by pressing the end E of the rod against an installation part such as a wall.

In addition, the press-fixed telescopic rod fall prevention member 1 is configured to include the front surface 4 formed on the bottom plate portion 2 and the back surface 5 formed on the bottom plate portion 2 . An adhesive member 6 is provided on the back surface 5 of the pressure-fixed telescopic rod fall prevention member 1 . In addition, in this specification, the part other than the connection member 6 of the press-fixed telescopic rod fall prevention member 1 is called "member body" B.

One surface of the bottom plate portion 2 is the front surface 4 , and the back side thereof is the back surface 5 . On the surface 4 side, the said restricting part 3 is provided so that it may protrude in the thickness direction TD (refer FIG. 3). Furthermore, a protrusion 7 is provided in the vicinity of the center of the surface 4 . The protrusions 7 are provided so as to protrude from the surface 4 in the thickness direction TD. The protruding portion 7 is located near the center of the bottom plate portion 2 , that is, the center of the restricting portion 3 in the front view of FIG. 1( b ). As shown in FIG. 3( a ), the protruding amount 7L of the protruding portion 7 from the surface 4 is shorter than the protruding amount 3L of the restricting portion 3 from the surface 4 . Although the external shape of the protruding portion 7 is cylindrical here, the external shape is not fixed, and may be, for example, a truncated cone shape, a square column shape, a plate shape, or the like.

The size of the protrusion 7 relative to the bottom plate 2 is preferably about 1/3D to 1/2D when the length of one side of the bottom plate 2 is D. For example, if one side of the bottom plate portion 2 is set to 30 mm, and the thickness of the cylindrical protrusion portion 7 is set to 1 mm, the inner diameter (diameter) of the protrusion portion 7 is preferably set to (30×1/3 -1×2=)8 mm～(30×1/2-1×2=)13 mm.

The protrusion part 7 is formed in the cylindrical shape which has the ridgeline part RP in the part of the top part, ie, the most front-end|tip. Here, the ridgeline portion RP of the protruding portion 7 is circular and has a length equal to or more than a predetermined length. The specific length can be set to, for example, 1 mm or more and 30 mm or less, or 5 mm or more and 10 mm or less. In addition, in FIG. 1, the ridgeline part RP is shown to have a certain width|variety for easy illustration and understanding. However, the ridge portion RP may be formed sharply. Here, the protruding portion 7 has an opening hole 7H at the front end thereof, and the ridge portion RP extends around the hole 7H. The hole 7H of the protruding portion 7 is closed by the bottom plate portion 2 here, but may be opened on the back surface 5 .

Moreover, in the pressure-fixed telescopic rod fall prevention member 1, the hole 2H is formed in the periphery of the protrusion part 7. As shown in FIG. The hole 2H is formed in the bottom plate portion 2 and is open on both surfaces of the front surface 4 and the back surface 5 . The hole 2H is a substantially U-shaped slot hole here. By forming the hole 2H, the installation portion 7S of the protruding portion 7 has a cantilever structure. Therefore, the installation portion 7S of the protruding portion 7 can be flexed (elastically deformed) in the thickness direction. Thus, the installation part 7S is a flexible part which can bend in the thickness direction TD, and the protrusion part 7 is provided in the vicinity of the front-end|tip.

The surface 4 of the press-fixed telescopic rod fall prevention member 1 is constituted as a surface to be in contact with the end E of the telescopic rod R. As shown in FIG. In this specification, the surface 4 mainly means a portion inside the restricting portion 3 . Although the surface 4 is a substantially smooth surface here, it is not limited to a smooth surface. The area of the surface 4 enclosed by the restriction|limiting part 3 should just be the area of the degree which can arrange|position at least the end part E of the telescopic rod R.

The back surface 5 is a part located on the back side of the front surface 4, and is a surface on the side of the wall surface W on which the fixed telescopic rod fall prevention member 1 is arranged under pressure. The adhesive member 6 is provided on the back surface 5 .

The above-mentioned restricting portion 3 is provided on the pressure-fixed telescopic rod fall prevention member 1 . The restricting part 3 restricts the arrangement area of the telescopic rod R. As shown in FIG. In this embodiment, the restricting part 3 has the cylindrical surface 3C as the inner surface. Therefore, the restricting part 3 not only restricts the arrangement area of the telescopic rods R, but also has a function of supporting the telescopic rods R. As shown in FIG. In particular, when the press-fixed telescopic rod fall prevention member 1 is provided on the wall surface W as shown in FIG. 2, the portion of the restricting portion 3 located on the lower side in the vertical direction is in the case where the telescopic rod R is in contact with the telescopic rod R. support it.

The press-fixed telescopic rod fall prevention member 1 is further provided with a sliding restraining structure S1 configured to restrain the back surface 5 from sliding with respect to the bonding member 6 . In the present embodiment, the slippage suppressing structure S1 includes a frame portion 11 serving as a convex portion defining the adhesion surface of the adhesive member 6 , and a hole 12 penetrating from the back surface 5 to the front surface 4 . In addition, the slip suppression structure 10 may have a recess provided in the back surface 5 in place of the hole 12 or in addition thereto. The hole 12 and the concave portion allow the adhesive member 6 to partially enter, and can exert an effect of suppressing sliding relative to the adhesive member 6 .

As shown in FIG. 3( a ), the press-fixed telescopic rod fall prevention member 1 fixed to the wall surface W as shown in FIG. 2 is shown. At this time, the adhesive member 6 is attached to the attachment surface in the quadrangular frame portion 11 of the back surface 5 . The adhesive member 6 is a kind of double-sided adhesive tape, and is also attached to the wall surface W. As shown in FIG. As the adhesive member 6, it is preferable to use, for example, a commercially available super double-sided tape. The protruding amount 11L of the frame portion 11 from the back surface 5 is designed so as not to reach the thickness of the bonding member 6 . The protruding amount 11L of the frame portion 11 may be, for example (more than 0 mm) 1 mm or less, more preferably 0.3 mm or more and 0.8 mm or less, and here is about 0.5 mm. On the other hand, the thickness of the adhesive member 6 is longer than the protrusion amount 11L of the frame portion 11, and may be, for example, 1.5 mm or more. As described above, since the press-and-fixed telescopic rod fall prevention member 1 includes the frame portion 11 , the back surface 5 , which is the member body B of the press-and-fixed telescopic rod fall prevention member 1 , can be preferably prevented from sliding relative to the bonding member 6 . . Therefore, the fall of the telescopic rod can be better prevented. In addition, although the frame part 11 is comprised by the continuous convex part in this embodiment, it may be comprised by a plurality of discontinuous convex parts. That is, the convex portion or the convex portions may be arranged to at least partially define the attachment surface of the adhesive member 6 .

Furthermore, the press-fixed telescopic rod fall prevention member 1 is provided with the hole 12 which penetrates from the back surface 5 to the front surface 4, as a sliding restraint structure S1. That is, the back surface 5 is provided with a dimple. In use as shown in FIG. 2, then a portion of the member 6 enters or bites into the depression of the hole 12. This is because the bonding member 6 has elastic properties. Therefore, the hole 12 can also better prevent the member body B of the press-fixed telescopic rod fall prevention member 1 from sliding and offset relative to the connecting member 6, and can better prevent the telescopic rod from falling. In addition, in the present embodiment, a plurality of, more specifically, four holes 12 are provided, but the number of holes 12 may be one or more. Also, the size and shape of the hole 12 may have various sizes and shapes.

In the press-fixed telescopic rod fall prevention member 1 having the above-described configuration, as described above, the protrusion 7 is provided in the center of the surface 4 . First, the functions and effects of the positioning of the telescopic rod R by the protruding portion 7 will be described.

As a method of using the press-fixed telescopic rod fall prevention member 1 , first, the press-fixed telescopic rod fall prevention member 1 is fixed to a wall surface portion that is an installation portion where the telescopic rod R is to be attached by the adhesive member 6 . In this state, the end portion E of the telescopic rod R is disposed in the disposition area of the telescopic rod surrounded by the restricting portion 3 . Furthermore, for example, the telescopic rod R performs the operation of extending the length. As a result, as schematically shown in FIG. 3( a ), the protrusion 7 is brought into contact with the end surface ES of the end E of the telescopic rod R, and the protrusion 7 acts as a locking portion and the end E of the telescopic rod R becomes stuck state. At this time, the protruding portion 7 may bite or pierce the end portion E, for example. In the present embodiment, the front end of the protruding portion 7 is configured as a ridge portion RP. Therefore, the protruding portion 7 easily bites into the end portion E of the telescopic rod R. As shown in FIG. Thereby, the deflection of the telescopic rod can be preferably prevented, thus, the loosening of the telescopic rod R can be prevented, and the possibility of falling of the telescopic rod can be further reduced. In this way, the end portion E of the telescopic rod R is stably maintained in the configuration area surrounded by the restricting portion 3 , and is more stably positioned at a preferred position, preferably supported, by the protruding portion 7 .

From the telescopic rod R supported by the protrusion 7 and positioned at a preferred position as described above, a substantially right angle is applied to the press-fixed telescopic rod fall prevention member 1, mainly to the back surface 5 of the press-fixed telescopic rod fall prevention member 1 The power of direction. It preferably brings about the pressing achieved by the adhesive member 6 , and thus, it is difficult to produce sliding of the back surface 5 with respect to the adhesive member 6 . Therefore, the member body B of the press-fixed telescopic rod fall prevention member 1 can be preferably prevented from sliding and offset relative to the connecting member 6, and the telescopic rod can be better prevented from falling.

Moreover, since the above-mentioned hole 2H is formed around the protruding portion 7, the installation portion 7S of the protruding portion 7 has a cantilever structure, and thus becomes a flexible portion. Therefore, the end surface ES of the end portion E of the telescopic rod R is brought into contact with the protrusion 7, and a force in the thickness direction is applied to the installation portion 7S of the press-fixed telescopic rod fall prevention member 1 through the protrusion 7, thereby causing The installation portion 7S can be deflected toward the back side in the thickness direction TD. Thereby, the setting portion 7S partially presses the bonding member 6, and the bonding by the bonding member 6 is preferably brought about as a whole, so that the sliding of the back surface 5 with respect to the bonding member 6 is difficult to occur. Therefore, the member body B of the press-fixed telescopic rod fall prevention member 1 can be preferably prevented from sliding and offset relative to the connecting member 6, and the telescopic rod can be better prevented from falling.

Furthermore, by arranging the protruding portion 7 of the present embodiment in the vicinity of the center of the bottom plate portion 2, the member body B is further less likely to be displaced. That is, previously, due to the vicious circle of (1) the member body B was rotated and shifted, (2) the length of the telescopic rod was shortened, (3) the pressing force was weakened, and (4) the member body B was more easily rotated, the member body B is shifted, and as a result, the force for pressing the bonding member 6 is weakened, and the whole is peeled off. On the other hand, according to this embodiment, by (1) the member body B is rotated and displaced, (2) the length of the telescopic rod is maintained by pressing the center, (3) the pressing force is maintained, and (4) the member body B is not easy to The virtuous cycle of rotation, and the component body B does not shift, maintains the force of pressing the component 6, and does not peel off as a whole.

Moreover, according to the press-fixed telescopic rod fall prevention member 1 as described above, the end E of the telescopic rod R is arranged in the arrangement area surrounded by the restricting portion 3, and can be supported by the lower part according to the situation, and It is stably supported by the protrusion 7 . Therefore, according to the press-fixed telescopic rod fall prevention member 1, the telescopic rod R can be prevented from falling more preferably.

Furthermore, as described above, according to the press-fixed telescopic rod fall prevention member 1, the sliding of the back surface 5 with respect to the bonding member 6 can be suppressed by the above-mentioned sliding restraining structure S1. Therefore, according to the press-fixed telescopic rod fall prevention member 1, the telescopic rod R can be prevented from falling even more preferably.

As described above, according to the press-fixed telescopic rod fall prevention member 1, since the above-mentioned configuration is provided, the telescopic rod can be prevented from falling more preferably.

Next, based on FIG. 4, the pressure-fixed telescopic rod fall prevention member 1A of the 2nd Embodiment of this invention is demonstrated. Hereinafter, with regard to the difference from the pressure-fixed telescopic rod fall prevention member 1 of the first embodiment, the pressure-fixed telescopic rod fall prevention member 1A will be described, and repeated descriptions will be omitted.

The sliding restraint structure S2 of the press-fixed telescopic rod fall prevention member 1A is also provided with the frame portion 11 as the convex portion that defines the attachment surface of the adhesive member 6 and the hole 12 penetrating from the back surface 5 to the front surface 4 . The convex part 20 provided in the back surface 5 is provided. A plurality of convex portions 20 are provided, and here, they are regularly arranged between the holes 12 . The protruding amount of each convex portion 20 may be shorter than the protruding amount of the frame portion 11, and here, it is determined to be about 0.1 mm. The convex portion 20 acts to bite into the adhesive member 6 , and can further suppress the sliding of the pressure-fixed telescopic rod drop prevention member 1A with respect to the adhesive member 6 .

Furthermore, in the press-fixed telescopic rod fall prevention member 1A, the protrusion 7 provided on the surface 4 is configured to have a substantially square bottom and a substantially elliptical top. In this way, the shape of the protruding portion 7 may be longitudinally long. In addition, the protruding part 7 is not limited to a vertical length, For example, a horizontal length may be sufficient as it. In addition, a ridge portion RP is formed on the top of the protruding portion 7 .

Moreover, in the press-fixed telescopic rod fall prevention member 1 of the first embodiment described above, the inner surface of the restricting portion 3 is the cylindrical surface 3C, but in the press-fixed telescopic rod fall prevention member 1A of the present embodiment , the inner surface of the restricting portion 3 is substantially U-shaped. Therefore, the arrangement area of the telescopic rod R surrounded by the restricting portion 3 can be further widened. Thereby, the installation operation of the telescopic rod R can be performed more easily. In addition, the U-shaped bent portion (the lower portion in FIG. 4 ) of the restricting portion 3 can be positioned on the lower side in the vertical direction when the press-fixed telescopic rod fall prevention member 1A is provided.

As described above, according to the press-fixed telescopic rod fall prevention member 1A, since the above-mentioned configuration is provided, the press-fixed telescopic rod fall prevention member 1 of the first embodiment can be preferably prevented from being pressed. The member body B of the fixed telescopic rod drop prevention member 1A is slidably displaced relative to the connecting member 6 . Therefore, according to the press-fixed telescopic rod fall prevention member 1A, the telescopic rod can be more preferably prevented from falling.

In addition, in the press-fixed telescopic rod fall prevention members 1 and 1A, although the restricting part 13 is continuous in an annular shape, for example, it may be partially interrupted. For example, slots may be provided between the lower portion, the upper portion, and the side portions. In addition, the press-fixed telescopic rod fall prevention members 1 and 1A may be made of a material other than synthetic resin, for example, synthetic rubber or metal.

Next, the pressure-fixed telescopic rod fall prevention member 30 according to the third embodiment of the present invention will be described with reference to FIGS. 5 to 7 . Hereinafter, the press-fixed telescopic rod fall prevention member 30 will be described focusing on the points of difference from the press-fixed telescopic rod fall prevention members 1 and 1A of the first and second embodiments.

Fig. 5 is a front view when the pressure-fixed telescopic rod fall prevention member 30 according to the third embodiment of the present invention is in the shape of a flat plate. FIG. 6 shows six sides of the press-fixed telescopic rod fall prevention member 30 when the press-fixed telescopic rod fall prevention member 30 shown in FIG. 5 is bent along the bending line BL indicated by the broken line in FIG. 5 to be in the use state picture. In addition, FIG. 7 is a sectional view taken along the line VII-VII of FIG. 6( c ) of the press-fixed telescopic rod fall prevention member 30 , showing the portion where the adhesive member 6 is provided.

The press-fixed telescopic rod fall prevention member 30 is composed of a single metal plate P, and includes a front surface 4, a back surface 5, lower restricting parts 31 and 31 at the lower part, an upper restricting part 32 at the upper part, and a lateral restricting part at the side part. 33 , 33 , and the bent portion 34 are formed. The lower restricting portion 31 , the upper restricting portion 32 , and the side restricting portion 33 protrude in the thickness direction TD in the use state ( FIGS. 6 and 7 ), and are provided as area restricting portions that restrict the arrangement area of the telescopic rods. In addition, the press-fixed telescopic rod fall prevention member 30 further includes the above-mentioned bonding member 6 .

The surface 4 of the press-fixed telescopic rod fall prevention member 30 is a surface that extends especially from the central body portion 30B thereof and is in contact with the end portion E of the telescopic rod R. As shown in FIG. The area of the surface 4 may be at least an area that allows the end portion E of the telescopic rod R to be arranged. The width WL and the height H (refer to FIG. 6( c )) of the central body portion 30B of the press-fixed telescopic rod fall prevention member 30 are respectively 2 cm to 10 cm, preferably about 2.5 cm to 5 cm, more preferably is about 3 cm, but may have dimensions other than that. This dimension can be similarly applied to the above-mentioned press-fixed telescopic rod fall prevention members 1 and 1A. In addition, the back surface 5 extends on the central body portion 30B of the press-fixed telescopic rod drop preventing member 30, in particular.

The lower restricting parts 31 and 31 are provided below the bending part 34 so as to restrict the arrangement area of the telescopic rod R. As shown in FIG. In the use state of FIG. 6 , the lower restricting parts 31 and 31 are bent so as to protrude in the direction of the telescopic rod R on the side of the surface 4 . Moreover, the lower restricting parts 31 and 31 extend up and down, and are provided symmetrically with respect to the center line C passing through the center. Moreover, the lower restricting parts 31 and 31 are spaced apart from each other. The lower restricting portions 31 and 31 can support, for example, a telescopic rod R installed substantially horizontally from the ground (floor) from an obliquely downward direction at the time of use. That is, as shown in FIG.5 and FIG.6(c), the bending line BL of the lower restricting parts 31 and 31 is inclined with respect to the width direction. The inclination angle α is here about 4ﾟ, but can be in the range of 3ﾟ to 10ﾟ, for example. Although the telescopic rod R is mainly positioned and held by the bent portion 34 as will be described later, it may be stably supported by the lower restricting portions 4 and 4 from an obliquely downward direction. In addition, the number of lower restricting parts is not limited to two, and may be one or three or more.

On the upper portion of the press-fixed telescopic rod fall prevention member 30 , that is, above the bending portion 34 to be described later, there is provided an upper restricting portion 32 constituted by an upper end portion of a metal plate. The upper restricting part 32 restricts the disposition area of the telescopic rod R, especially the disposition area of the upper part. When the upper restricting portion 32 is in the use state of FIG. 6 , it is bent so as to protrude in the direction of the telescopic rod R on the side of the surface 4 .

Each side portion in the width direction (direction perpendicular to the vertical direction) of the press-fixed telescopic rod fall prevention member 30 is provided with a side end portion formed from a metal plate on the side of the bending portion 34 described later. The side restricting parts 33 and 33 are constituted. The side restricting portions 33 and 33 restrict the disposition area of the telescopic rod R, especially the disposition area of the side portion. When the side restricting portions 33 and 33 are in the use state of FIG. 6 , they are bent so as to protrude in the direction of the telescopic rod R on the side of the surface 4 .

The bent portion 34 of the press-fixed telescopic rod fall prevention member 30 is formed here as a protrusion for positioning the telescopic rod. The bent portion 34 is provided above the lower restriction portions 31 , 31 , below the upper restriction portion 32 , and between the two side restriction portions 33 , 33 . In the press-fixed telescopic rod fall prevention member 30 shown in FIG. 5 , the bent portion 34 is a part of the flat metal plate and does not protrude in the thickness direction. In FIGS. 5 and 6( c ), the bent portion 34 is positioned at the approximate center of the central body portion 30B of the press-fixed telescopic rod fall prevention member 30 . Here, the bent portion 34 is formed by punching in three directions, here, the left-right direction and the downward direction, to form a hole 30H so as to be a rectangular protruding portion. In addition, the bent portion 34 may have a shape other than a rectangle. The bent portion 34 is configured to protrude by being bent. When the bent portion 34 is in the use state of FIGS. 6 and 7 , it is bent so as to protrude toward the direction of the telescopic rod R on the surface 4 side, that is, the thickness direction TD. Since the bent portion 34 is positioned at the approximate center of the central body portion 30B of the press-fixed telescopic rod fall prevention member 30 , it protrudes toward the end surface ES of the end E of the telescopic rod R when in use. By this bending, the bending part 34 is formed so that it may extend in the width direction orthogonal to an up-down direction. However, the bent portion 34 may be provided to extend in the up-down direction. That is, the bent portion 34 is not limited to be formed to be horizontally long, and may be formed to be vertically long, for example.

By bending, the front end of the bent portion 34 constitutes a ridge portion RP. As shown in FIG. 7 , the ridge portion RP has the thickness of a plate and is not formed sharply. However, the ridge portion RP of the bent portion 34 may be formed sharply. Further, the ridge portion RP has a length equal to or greater than a predetermined length.

The length of the bent portion 34 , that is, the protruding length is shorter than the length of the lower support portion 31 , the length of the upper restriction portion 32 , and the length of the side restriction portion 33 . Here, the length of the bent portion 34 is about 3 mm, and the respective lengths of the lower support portion 31 , the upper restraint portion 32 and the side restraint portion 33 are about 8 mm (see FIG. 7 ). As described above, here, the protruding amount of the bent portion 34 is less than half of the protruding amount of each of the lower support portion 31 , the upper restricting portion 32 , and the side restricting portion 33 .

Furthermore, the press-fixed telescopic rod fall prevention member 30 has a slippage suppressing structure S3. In addition to the above-mentioned hole 12 penetrating from the back surface 5 to the front surface 4 , the sliding restraint structure S3 is also provided with a substantially U-shaped hole 30H provided around the bent portion 34 for forming the bent portion 34 . When the bent portion 34 is bent so as to protrude in the thickness direction, the hole 30H expands and becomes a substantially rectangular hole 34H as shown in FIG. 6 .

Here, the manufacturing method of the press-fixed telescopic rod fall prevention member 30 which has the above-mentioned structure is demonstrated. The press-fixed telescopic rod drop preventing member 30 can be formed by a rectangular or square thin metal plate. Here, by punching such a thin metal plate, a flat-plate-shaped press-fixed telescopic rod fall preventing member 30 as shown in FIG. 5 can be obtained. Then, by bending the above-mentioned parts 31 , 32 , 33 , 34 along the bending line BL indicated by the dotted line in FIG. The adhesive member 6 is attached to the back surface 5 of the metal plate in which the parts 31, 32, 33, and 34 are bent.

Here, the method of using the pressure-fixed telescopic rod fall prevention member 30 having the above-described configuration will be described. First, the press-fixed telescopic rod fall prevention member 30 in the use state of FIG. 6 is fixed to the wall surface portion which is the installation portion where the telescopic rod R is to be attached by the adhesive member 6 . At this time, the direction of the press-fixed telescopic rod fall prevention member 30 is determined so that the lower restricting portion 31 is positioned downward.

Therefore, like the installation part 7S of the bending part 7 of 1st and 2nd embodiment, the installation part 34S of the bending part 34 can be flexed in the thickness direction TD, and it can implement|achieve more favorable adhesion|attachment of the bonding member 6.

As mentioned above, the pressure-fixed telescopic rod fall prevention members 1, 1A, 30, and 30A of the first to fourth embodiments of the present invention have been described. As described above, by pressing the fixed telescopic rod drop prevention members 1, 1A, 30, 30A, the possibility of the telescopic rod R falling down can be further reduced, so even if the thickness of the telescopic rod is relatively thinned or reduced , or the thickness of its end E, can also stably support curtains and the like hanging on the telescopic rod R. For example, by using the press-fixed telescopic rod fall prevention members 1, 1A, 30, and 30A, the diameter of the telescopic rod R can be suppressed to about 2 cm even when suspending a somewhat heavy object or less, the end portion E of the telescopic rod R may be downsized, and the pressure-fixed telescopic rod fall prevention member 1 may be downsized. Therefore, the range of use and installation place of the telescopic rod R and the press-fixed telescopic rod fall prevention members 1 , 1A, 30 , and 30A can be further widened.

As described above, according to the press-fixed telescopic rod drop preventing members 1 , 1A, 30 , 30A, the telescopic rod R can be prevented from falling more preferably, so that the end E of the telescopic rod R is opposite to the main body RB of the telescopic rod R The size of the cross-sectional diameter can be reduced compared with the former. Therefore, for example, as shown in FIG. 9 , in a slight area of the door frame DF with the step difference of the hinge door Do (opened in FIG. 9 ), it is also possible to use the press-fixed telescopic rod fall prevention member 1 to install it. The telescopic rod R1 having the end portion E miniaturized as described above. In addition, the same applies to the pressure-fixed telescopic rod fall prevention members 1A, 30, and 30A.

Moreover, the adhesive member 6 connects the back surface 5 and the wall surface W, and supports and prevents the telescopic rod R from falling. Next, the member 6 usually uses a commercially available double-sided tape. The member 6 can then be removed without damaging the wall for installation or the like.
