Description

The present invention relates to a fixture installation structure and a fixture.

For example, in order to prevent objects to be fixed such as furniture from falling in the event of an earthquake, the objects to be fixed are fixed to an installation part using a fixture (for example, see Patent Document 1). The fixture includes a pair of flat plates facing each other. Further, the fixture includes a male threaded rod protruding from opposite sides of the pair of flat plates, and the lead angles of the pair of male threaded rods are in opposite directions.

The fixture also includes adhesive means having an adhesive surface on the other side of each flat plate. The adhesive means is made of gel-like ultra-soft urethane with adhesive properties. Furthermore, the fixture includes a cylindrical body. A female thread is formed on the inner peripheral surface of the cylindrical body. One male threaded rod is screwed into one end of the cylindrical body. The other male threaded rod is screwed onto the other end of the cylindrical body.

Then, the fixture is placed at an appropriate position on the installation part below the device with casters as the object to be fixed. At this time, the adhesive means attached to one of the flat plates is attached to the installation part. By rotating the cylindrical body, the other flat plate approaches the bottom surface of the device with casters, and furthermore, the adhesive means is affixed to the bottom surface of the device with casters. By further rotating the cylindrical body, both adhesive means are compressed in the thickness direction. Then, the caster-equipped device is fixed to the installation part by adhesion of the compressed adhesive means.

The second mat sticking surface 31a has a larger area than the second adhesive mat 32. Further, the shape of the second mat sticking surface 31a matches the square shape that is the shape of the second adhesive mat 32.

Note that since the second adhesive mat 32 is an adhesive mat having the same configuration as the first adhesive mat 22, a detailed description thereof will be omitted. The second adhesive mat 32 has a first surface 32a in the thickness direction attached to a second mat attachment surface 31a. The second surface 32b of the second adhesive mat 32 in the thickness direction constitutes the second adhesive surface of the second adhesive base 30. The second surface 22b of the second adhesive mat 32 is adhered to the floor surface Fa. In the fixture 11, the second surface 32b of the second adhesive mat 32 faces in a direction opposite to the second surface 22b of the first adhesive mat 22. In this embodiment, the second surface 22b of the first adhesive mat 22 faces upward, and the second surface 32b of the second adhesive mat 32 faces downward.

The second base body 31 includes a second frame portion 31c on the periphery of the second base body 31. The second frame portion 31c protrudes from the second mat attachment surface 31a in a square frame shape. The second frame portion 31c surrounds the second mat attachment surface 31a.

The second adhesive base 30 includes a cylindrical portion 33 that projects from the center of the back surface 31b of the second base main body 31 in a cylindrical shape. A second threaded portion 34 is provided on the outer peripheral surface of the cylindrical portion 33 . Therefore, the second adhesive base 30 has a second screwed part 34 on the back surface 31b of the second base main body 31. The second threaded portion 34 is a male thread provided on the outer peripheral surface of the cylindrical portion 33 . In this embodiment, the second threaded portion 34 is provided over the entire axial direction of the cylindrical portion 33 .

In the male thread of the second screwed part 34, the back side 31b of the second base main body 31 is the base end of the second screwed part 34, and the tip of the cylindrical part 33 is the tip of the second screwed part 34. shall be. The dimension from the base end to the tip of the second screwed part 34 along the axial direction of the cylindrical part 33 is defined as the second screwed length L2. The second threaded length L2 of the second threaded part 34 is longer than the first threaded length L1 of the first threaded part 24. Therefore, the dimension of the first screwed part 24 in the facing direction Y is smaller than the dimension of the second screwed part 34 in the facing direction Y. Note that the outer diameter of the second threaded portion 34 when the male thread is the same as the outer diameter of the first threaded portion 24 when the male thread is formed. Therefore, the first screwed part 24 and the second screwed part 34 have different dimensions in the facing direction Y and have the same outer diameter. Note that the outer diameter of the first screwed portion 24 and the second screwed portion 34 may be different.

The screw direction of the second screwed part 34 is a second screw direction opposite to the first screw direction of the first screwed part 24. Therefore, the first screwed part 24 and the second screwed part 34 have a reverse thread relationship.
The second adhesive base 30 has a space recess 31d located inside the cylindrical portion 33. The space recess 31d is recessed in a cylindrical shape inside the cylindrical portion 33 from the back surface 31b side of the second base main body 31 toward the second mat attachment surface 31a. In this embodiment, the space recess 31d penetrates the second base main body 31 in the thickness direction.

The connecting member 40 also includes a disk portion 43 that connects the inner peripheral edge of the first cylindrical portion 41 and the outer peripheral edge of the second cylindrical portion 42 . The disk portion 43 extends in the radial direction of the second cylindrical portion 42 from the end of the second cylindrical portion 42 closer to the first cylindrical portion 41 .

The connecting member 40 includes a first threaded portion 41 a on the inner peripheral surface of the first cylindrical portion 41 . The first threaded portion 41a is a female thread. Further, the connecting member 40 includes a second threaded portion 42a on the outer circumferential surface of the second cylindrical portion 42. The second threaded portion 42a is a male thread. The first threaded portion 41a and the second threaded portion 42a have the same thread direction. The first threaded portion 41 a and the second threaded portion 42 a have the same first threaded direction as the first threaded portion 24 .

In the female thread of the first threaded part 41a, the part near the disk part 43 is the base end of the first threaded part 41a, and the part near the tip of the first cylindrical part 41 is the tip of the first threaded part 41a. The dimension from the proximal end to the distal end of the first threaded portion 41a along the axial direction of the connecting member 40 is defined as the first thread length. The first thread length of the first threaded portion 41a is the same as the first threaded length L1 of the first threaded portion 24. Further, the first screwing length L1 is a length that allows the first screwed portion 24 and the first threaded portion 41a to be screwed together.

In the male thread of the second threaded part 42a, the part near the disk part 43 is the base end of the second threaded part 42a, and the part near the tip of the second cylindrical part 42 is the tip of the second threaded part 42a. The dimension from the base end to the distal end of the second threaded portion 42a along the axial direction of the connecting member 40 is defined as the second thread length.

The first screw portion 41 a is screwed into the first screwed portion 24 of the first adhesive base 20 . The first screw portion 41 a can be screwed over the entire first screwed portion 24 . When the first screw portion 41 a is screwed into the entire first screwed portion 24 , the tip of the first cylindrical portion 41 can be brought into contact with the back surface 21 b of the first base body 21 . Moreover, when the first screw portion 41 a is screwed into the entire first screwed portion 24 , the tip of the shaft portion 23 can be brought into contact with the inner surface of the disk portion 43 . A state in which the first screw portion 41a is screwed onto the entire first screwed portion 24 is defined as a first screwed position R1. At the first screwing position R1, by screwing the first threaded portion 41a back from the first screwed portion 24, the connecting member 40 can be separated from the first adhesive base 20.

The connecting member 40 has a first threaded portion 41a at a first end in the axial direction, and a second threaded portion 42a at a second end in the axial direction. In the axial direction of the connecting member 40, the first end side of the disk portion 43 is a first threaded portion 41a, and the second end side of the disk portion 43 is a second threaded portion 42a.

As described above, the connecting member 40 can be connected to the first adhesive base 20 by screwing the first screw portion 41a and the first screwed portion 24 together. A moving operation member 50, which will be described later, is screwed into the second threaded portion 42a of the connecting member 40.

The moving operation member 50 has a double cylinder shape. The movement operation member 50 includes an inner cylinder part 51, an outer cylinder part 52 on the outer peripheral side of the inner cylinder part 51, and a connecting part 53 that connects the first ends of the inner cylinder part 51 and the outer cylinder part 52 in the axial direction. , has. The moving operation member 50 has a double cylindrical shape in which an inner cylinder part 51 and an outer cylinder part 52 overlap in the radial direction of the movement operation member 50. The inner diameter and outer diameter of the outer cylinder part 52 are larger than the inner diameter and outer diameter of the inner cylinder part 51. Further, the connecting portion 53 connects the outer peripheral edge of the inner cylinder portion 51 and the inner peripheral edge of the outer cylinder portion 52. The inner peripheral surface of the outer cylinder part 52 is spaced apart from the outer peripheral surface of the inner cylinder part 51 in the radial direction by the connecting part 53 . The connecting portion 53 connects the first ends of the inner tube portion 51 and the outer tube portion 52 in the axial direction to each other in the radial direction.

Regarding the dimensions of the inner cylinder part 51 and the outer cylinder part 52 in the axial direction of the moving operation member 50, the outer cylinder part 52 is larger. The moving operation member 50 has a connecting screw portion 51a on the inner circumferential surface of the inner cylinder portion 51. The connecting threaded portion 51a is a female thread. The connecting threaded portion 51a is screwed into the second threaded portion 42a of the connecting member 40.

In the female thread of the connecting threaded portion 51a, the distal end of the inner cylindrical portion 51 is the distal end of the connecting threaded portion 51a, and the distal end of the connecting threaded portion 51a is the proximal end of the connecting threaded portion 51a. The length from the base end to the distal end of the connecting screw portion 51a along the axial direction of the moving operation member 50 is smaller than the second screw length of the second screw portion 42a. Therefore, the connecting threaded portion 51a is screwed into a portion of the second threaded portion 42a in the axial direction.

The moving operation member 50 includes an operation screw portion 52a on the inner circumferential surface of the outer cylinder portion 52. The operating threaded portion 52a is a female thread. In the female thread of the operating threaded portion 52a, a portion closer to the connecting portion 53 is the base end of the operating threaded portion 52a, and a portion closer to the tip of the outer cylinder portion 52 is the tip of the operating threaded portion 52a. The length from the proximal end to the distal end of the operating screw portion 52a along the axial direction of the movable operating member 50 is the same as the second threaded length L2 of the second threaded portion 34. The operation screw portion 52a can be screwed over the entire second screwed portion 34.

When the operation screw portion 52a is screwed into the entire second screwed portion 34, the tip of the outer cylinder portion 52 can be brought into contact with the back surface 31b of the second base body 31. Further, when the operating threaded portion 52 a is screwed into the entire second screwed portion 34 , the axial end of the cylindrical portion 33 can be brought into contact with the inner surface of the connecting portion 53 .

As shown in FIG. 4, the position where the operating screw part 52a is screwed into the entire second screwed part 34 is defined as a second screwed position R2. The second screwing position R2 is also a position where the operation screw portion 52a is screwed into the second screwed portion 34 until the movable operation member 50 is closest to the second adhesive base 30 side.

At the second screwing position R2, the moving operating member 50 is rotated in the direction in which the operating screw portion 52a and the second screwed portion 34 are released. 2 can be separated from the adhesive base 30. Further, the connecting member 40 can be screwed forward with respect to the moving operation member 50, and the disc part 43 can be brought into contact with the connecting part 53.

The thread direction of the operation thread part 52a is opposite to the thread direction of the connection thread part 51a. In other words, the operating threaded portion 52a and the connecting threaded portion 51a have a reverse threaded relationship. The screw direction of the operation screw portion 52a is the same second screw direction as that of the second screwed portion 34. The thread directions of the first threaded part 24, the first threaded part 41a, the second threaded part 42a, and the connection threaded part 51a are the first thread direction, and the second threaded part 34 and the operating screw The thread direction of the portion 52a is the second thread direction.

The movable operating member 50 is threadedly rotated so that the movable operating member 50 moves away from or approaches the second adhesive base 30 . At this time, when the moving operation member 50 is rotated together with the connecting member 40, the connecting member 40 can be moved by the same amount as the moving distance accompanying the screw rotation operation of the moving operating member 50. Further, since the first screwed portion 24 of the first adhesive base 20 is screwed into the first screw portion 41a of the connecting member 40, the connecting member 40 and the first adhesive base 20 cannot be moved together. I can do it.

Further, when the movable operating member 50 is rotated so that the movable operating member 50 moves away from or approaches the second adhesive base 30, only the movable operating member 50 is operated by screw rotation without rotating the connecting member 40. . Since the connecting screw portion 51a and the operating screw portion 52a have a reverse thread relationship, the second adhesive base 30 and the connecting member 40 move away from or close to the movable operating member 50, and the connecting member 40 is moved away from the movable operating member 50. It can be moved by an amount greater than the distance traveled. Further, since the first screwed portion 24 of the first adhesive base 20 is screwed into the first screw portion 41a of the connecting member 40, the connecting member 40 and the first adhesive base 20 cannot be moved together. I can do it.

As described above, by screwing and rotating the moving operation member 50 with respect to the connecting member 40, the first adhesive base 20 and the second adhesive base 30 can be relatively moved toward and away from each other via the connecting member 40. .

Further, in the fixture 11, the first threaded portion 41a, the second threaded portion 42a, and the connecting threaded portion 51a have a first threaded direction. On the other hand, the first threaded portion 41a and the operating threaded portion 52a have a reverse threaded relationship. Therefore, when the connecting member 40 is screwed and rotated with respect to the first screwed part 24, unless the moving operation member 50 is rotated, the connecting member 40 will be rotated with respect to the first adhesive base 20 and the moving operation member 50. Only the screw can be rotated.

In the connecting member 40 located at the first screwing position R1, the direction in which the screwing operation is performed in order to release the screwing between the first threaded part 41a and the first screwed part 24 is determined by the screwing direction of the connecting member 40. direction. The spiraling direction is the direction in which the connecting member 40 faces the second adhesive base 30. The movement of the connecting member 40 in the spiraling direction is referred to as "spiraling." As the connecting member 40 spirals, the second threaded portion 42 a enters inside the moving operation member 50 and the cylindrical portion 33 of the second adhesive base 30 . The space recess 31d of the second adhesive base 30 allows the tip of the second threaded portion 42a to enter the second base body 31 closer to the back surface 31b than the second mat attachment surface 31a. Therefore, the space recess 31d has a shape that is depressed in the direction where the connecting member 40 is screwed.

In the fixture 11, when the first adhesive base 20 and the second adhesive base 30 are spaced apart in the facing direction Y by the screw rotation operation of the moving operation member 50, the first threaded portion relative to the first screwed portion 24 is The connection between the first adhesive base 20 and the connection member 40 is released by threading the connection member 40 until the screwing of the first adhesive base 20 and the connection member 41a is released. That is, by screwing (moving) the connecting member 40 toward the second adhesive base 30 until the first threaded part 41a is unscrewed from the first screwed part 24, the connecting member 40 is removed from the first adhesive base 20. The connecting member 40 can be separated. In other words, the fixture 11 is configured such that only the connecting member 40 can be threaded until the first screw portion 41a is unscrewed from the first screwed portion 24. That is, in the fixture 11, the first screwed part 24 and the first threaded part 41a can be unthreaded by the screwing of the connecting member 40. Then, by screwing the connecting member 40 until the first screw portion 41a is unscrewed from the first screwed portion 24, the fixing state between the floor surface Fa and the fixing object 10 by the fixture 11 can be released. .

To release the screwing between the first screwed part 24 and the first threaded part 41a, create a space in which the connecting member 40 can move by screwing a distance longer than the first screwing length L1. It is necessary to secure a moving distance between the connecting member 40 and the moving operation member 50 in the facing direction Y. Further, when the connecting member 40 spirals, it is necessary to secure a space into which the tip of the second threaded portion 42a enters. Hereinafter, in order to release the threaded connection between the first threaded part 41a and the first threaded part 24, a space in which the connecting member 40 can move by a distance longer than the first threaded length L1 will be referred to as a movement permissible space D. do.

The dimension of the movement permissible space D in the facing direction Y needs to be longer than the first threaded length L1 of the first threaded part 24. Specifically, in a state where the first adhesive base 20 and the second adhesive base 30 are separated in the facing direction Y by the screw rotation operation of the movable operating member 50, the connecting portion 53 of the movable operating member 50 and the connecting member 40 and the disc portion 43 needs to be longer than the first screwing length L1. Furthermore, in a state where the first adhesive base 20 and the second adhesive base 30 are separated in the facing direction Y by the screw rotation operation of the moving operation member 50, the distance between the tip of the second screw portion 42a and the floor surface Fa is The length needs to be longer than the first screw length L1.

The fixture 11 secures a movement permissible space D that is longer than the first screw length L1 between the connecting member 40 and the moving operation member 50 by the space forming member 60.
As shown in FIG. 2 or 4, the space forming member 60 includes an attachment portion 61 that is attached to the second threaded portion 42a of the connection member 40, and a restriction portion 62 that is integrated with the attachment portion 61. . The attachment portion 61 has a plate shape that is curved in an arc shape. The direction in which the central axis of the arc of the attachment portion 61 extends is defined as the axial direction. The attachment part 61 has a first end edge 61a extending in an arc shape at one end in the axial direction, and a second end edge 61b extending in an arc shape at the other end in the axial direction of the attachment part 61. The first edge 61a and the second edge 61b face each other in the axial direction and are parallel to each other. In the axial view of the attachment portion 61, the arc of the first end edge 61a and the second end edge 61b is an arc along the arc of the second threaded portion 42a. That is, the radius of the circular arc of the attachment portion 61 when viewed in the axial direction is slightly larger than the radius of the second threaded portion 42a.

When viewed in the axial direction of the attachment portion 61, both ends of the attachment portion 61 are elastically deformable. By elastically deforming both ends of the arc of the attachment portion 61, the second threaded portion 42a can be passed between the attachment portions 61 in the radial direction. Further, after the second threaded portion 42a passes between both ends of the arc of the attachment portion 61, both ends of the attachment portion 61 can be made to follow the arc of the second threaded portion 42a.

The regulating portion 62 includes a bottom portion 62a extending from a first end edge 61a in the axial direction of the attachment portion 61, and a covering portion 62b standing up from the outer peripheral edge of the bottom portion 62a. The bottom portion 62a extends semicircularly along the radial direction of the arc of the attachment portion 61. The covering portion 62b has a semi-cylindrical shape and stands upright in the axial direction of the attachment portion 61 from the outer peripheral edge of the bottom portion 62a. The bottom portion 62a covers the disk portion 43 of the connecting member 40 from the first threaded portion 41a side. The covering portion 62b covers the first threaded portion 41a of the connecting member 40 from the outer peripheral side. The covering portion 62b covers the entire first screw portion 41a in the axial direction of the connecting member 40 from the outer peripheral side.

The space forming member 60 is configured such that the disk portion 43 contacts the bottom portion 62a of the regulating portion 62 while the second end edge 61b of the attachment portion 61 in the axial direction contacts the connecting portion 53 of the moving operation member 50. , the screwing of the connecting member 40 toward the second adhesive base 30 is restricted. That is, the restricting portion 62 restricts the movement of the connecting member 40 in the direction of narrowing the movement permissible space D by contacting the connecting member 40 . The dimension between the first end edge 61a and the second end edge 61b along the axial direction of the attachment portion 61 is longer than the first screw length L1. Therefore, by bringing the second end edge 61b into contact with the connecting part 53 and bringing the regulating part 62 into contact with the disc part 43, the first threaded connection is made between the connecting member 40 and the moving operation member 50. A movement permissible space D that is longer than the length L1 can be secured.

In addition, when the space forming member 60 secures the movement permissible space D between the connecting member 40 and the movement operation member 50, there is also a movement permissible space between the tip of the second screw portion 42a and the floor surface Fa. D is secured. Therefore, the movement permissible space D is composed of the inner space of the second screwed part 34 and the space recess 31d.

Next, the installation structure of the fixture 11 will be explained.
As shown in FIG. 5, in the installation structure of the fixture 11, the second surface 22b of the first adhesive mat 22 is adhered to the lower surface 10a of the object to be fixed 10, and the second surface 32b of the second adhesive mat 32 is attached to the floor. It is attached to the surface Fa. In the installation structure of the fixture 11, the first screwed part 24 of the first adhesive base 20 is erected from the first base main body 21 in the facing direction Y, and the second screwed part 34 of the second adhesive base 30 is erected from the first base main body 21 in the facing direction Y. It is erected from the second base main body 31 in the facing direction Y. Furthermore, in the installation structure of the fixture 11, the first adhesive mat 22 is compressed and deformed in the thickness direction so that a desired adhesive force can be exerted between the first mat sticking surface 21a and the lower surface 10a. Similarly, the second adhesive mat 32 is compressed and deformed in the thickness direction so that a desired adhesive force can be exerted between the second mat sticking surface 31a and the floor surface Fa.

In the installation structure of the fixture 11, the moving operation member 50 is attached to the first adhesive base 20 in a state in which the first adhesive mat 22 is attached to the lower surface 10a and the second adhesive mat 32 is attached to the floor surface Fa. The connecting member 40 is brought close to the fixed object 10 by performing a screw rotation operation toward the connecting member 40 . Therefore, the first adhesive base 20 and the second adhesive base 30 are urged in the direction of separation in the facing direction Y by the connecting member 40 and the moving operation member 50. The first adhesive mat 22 and the second adhesive mat 32 are compressed in the thickness direction by urging the first adhesive base 20 and the second adhesive base 30 in the direction of separation in the facing direction Y. In this embodiment, the first adhesive mat 22 and the second adhesive mat 32 are compressed to have a thickness of 50% to 90% of the thickness before compression.

Next, a method for installing the fixture 11 will be explained.
As shown in FIG. 4, in the fixture 11, the attachment part 61 of the space forming member 60 is attached to the second threaded part 42a of the connecting member 40, and the outer peripheral side of the first cylindrical part 41 A regulating portion 62 is attached to the. Note that the space forming member 60 may be removed from the connecting member 40 and attached to the connecting member 40 when the fixture 11 is installed.

A movement permissible space D is secured between the connecting member 40 and the moving operation member 50 by the space forming member 60 . In the fixture 11 including the space forming member 60, the distance between the second surface 22b of the first adhesive mat 22 and the second surface 32b of the second adhesive mat 32 is equal to the distance between the lower surface 10a of the object to be fixed 10 and the floor surface Fa. It is assumed that the distance is shorter than the distance of

Next, the fixing tool 11 is arranged between the lower surface 10a of the fixed object 10 and the floor surface Fa, and the fixing tool 11 is arranged below the lower surface 10a of the fixed object 10, and the second adhesive base 30 2. Place the adhesive mat 32 on the floor surface Fa and attach it. Then, the moving operation member 50 is screwed and rotated to bring the connecting member 40 and the first adhesive base 20 close to the fixed object 10. That is, the moving operation member 50 is screwed and rotated to separate the first adhesive base 20 and the second adhesive base 30. Then, the connecting member 40 separates from the moving operation member 50 along the facing direction Y, and the movement permissible space D between the connecting member 40 and the moving operating member 50 expands in the facing direction Y. At the same time, the movement permissible space D between the tip of the second threaded portion 42a and the floor surface Fa is also expanded in the facing direction Y.

Then, as shown in FIG. 5, the second surface 22b of the first adhesive mat 22 is attached to the lower surface 10a of the object to be fixed 10. At this time, a movement permissible space D is secured between the connecting member 40 and the moving operation member 50. Note that in FIG. 5, illustration of the space forming member 60 is omitted.

Next, the moving operation member 50 is screwed to move the connecting member 40 and the first adhesive base 20 closer to the fixed object 10, and the first adhesive base 20 and the second adhesive base 30 are separated. Then, the first adhesive mat 22 and the second adhesive mat 32 are compressed and deformed. At this time, the amount of screw rotation of the movable operating member 50 is adjusted so that the thickness of each adhesive mat 22, 32 is compressed and deformed to 50% to 90% of the thickness before compression.

Further, the movement operation is performed such that the first frame portion 21c of the first adhesive base 20 is separated from the lower surface 10a of the fixed object 10, and the second frame portion 31c of the second adhesive base 30 is separated from the floor surface Fa. The amount of screw rotation of the member 50 is adjusted.

Then, the second surface 22b of the first adhesive mat 22 is attached to the lower surface 10a of the fixed object 10, and the second surface 32b of the second adhesive mat 32 is attached to the floor surface Fa. As a result, the fixing object 10 is fixed to the floor surface Fa by the fixture 11.

Now, when it is desired to move the fixed object 10 from the fixed position by the fixture 11, the attachment part 61 of the space forming member 60 is removed from the second threaded part 42a, and the regulating part 62 is removed from the first cylindrical part 41. , the restriction portion 62 is not arranged with respect to the fixture 11. By not disposing the restricting portion 62, the connecting member 40 can be moved in the direction of narrowing the movement permissible space D, and the first screw portion 41a can be unscrewed from the first screwed portion 24. Note that the space forming member 60 may be removed at any time after the first adhesive mat 22 is attached to the object 10 to be fixed.

As shown in FIG. 6, the connecting member 40 is spirally advanced toward the second adhesive base 30 so that the connecting member 40 approaches the moving operation member 50. At this time, the first adhesive base 20 is adhered to the fixed object 10 by the first adhesive mat 22, and the second adhesive base 30 is adhered to the floor surface Fa by the second adhesive mat 32. Therefore, the first adhesive base 20 and the second adhesive base 30 cannot rotate.

Since the first threaded part 41a of the connecting member 40 and the first threaded part 24 have the same screw direction, the first threaded part 41a is screwed into the first threaded part 24 by the screw rotation operation for threading the connecting member 40. It can be moved in the direction in which the threaded engagement with the joint portion 24 is released.

Further, the second threaded portion 42a of the connecting member 40 is screwed into the connecting threaded portion 51a of the movable operation member 50, while the operating threaded portion 52a, which has an opposite thread to the connecting threaded portion 51a, It is screwed into the second screwed part 34 of the adhesive base 30 . Therefore, when the connecting member 40 is screwed and the first screw portion 41a is moved in the direction in which the screwing with the first screwed portion 24 is released, the connecting member 40 is moved toward the second adhesive base 30. The moving operation member 50 is then spirally advanced. At this time, since a movement permissible space D is secured between the connecting member 40 and the moving operation member 50 and between the tip of the second threaded portion 42a and the floor surface Fa, the connecting member 40 is moved to the first The threaded part 24 can be moved a distance longer than the first threaded length L1. The connecting member 40 then spirals in a direction that narrows the movement allowable space D.

As shown in FIG. 7, the connecting member 40 is moved toward the second adhesive base 30 until the first threaded portion 41a and the first screwed portion 24 are disengaged from each other. The connection of the first adhesive base 20 is released. Thereafter, the fixed object 10 is moved along the floor surface Fa together with the first adhesive base 20.

According to the above embodiment, the following effects can be obtained.
(1) When the connecting member 40 is screwed forward in order to release the screwing between the first screw portion 41a and the first screwed portion 24, the second screw portion 42a is a connecting screw portion of the moving operation member 50. 51a, and the second threaded portion 42a independently threads into the second screwed portion 34 of the second adhesive base 30. Therefore, even if the second surface 22b of the first adhesive mat 22 is adhered to the lower surface 10a and the second surface 32b of the second adhesive mat 32 is adhered to the floor surface Fa, the connecting member 40 is moved by the operation member 50. By screwing it forward, the first adhesive base 20 and the connecting member 40 can be unscrewed, and the first adhesive base 20 can be separated from the connecting member 40. As a result, the second surface 22b of the first adhesive mat 22 is stuck to the lower surface 10a of the fixed object 10, and the second surface 32b of the second adhesive mat 32 remains stuck to the floor surface Fa. The fixed object 10 can be moved from the floor surface Fa. That is, the fixed object 10 can be moved without peeling off the second surface 22b of the first adhesive mat 22 from the lower surface 10a or peeling off the second surface 32b of the second adhesive mat 32 from the floor surface Fa.

Further, for example, the work of peeling off the second surface 22b of the first adhesive mat 22 from the lower surface 10a of the fixed object 10 can be performed while the fixed object 10 is moved from the floor surface Fa, and the first adhesive mat There is no need to perform the work of peeling off the second surface 22b of 22 between the lower surface 10a and the floor surface Fa, improving work efficiency. Moreover, when it is desired to clean between the lower surface 10a of the fixed object 10 and the floor surface Fa, the fixed object 10 can be moved from the floor surface Fa and cleaned, making it easy to perform the cleaning work. Furthermore, since it is not necessary to peel off the first adhesive mat 22 and the second adhesive mat 32 from the surface to which they are attached, the fixing object 10 can be returned to its original position on the floor surface Fa using the fixture 11 after cleaning. I can do it.

(2) In the installation structure of the fixture 11, when the connecting member 40 is screwed until the first screw portion 41a is unscrewed from the first screwed portion 24, the first cylindrical portion The portion 41 can be removed. Therefore, when the first threaded part 41a is unscrewed from the first threaded part 24, the fixed object 10 can be slid together with the first adhesive base 20 along the floor surface Fa.

(3) The first threaded length L1 of the first threaded part 24 is shorter than the second threaded length L2 of the second threaded part 34. Therefore, the amount of screw rotation of the connecting member 40 required to extract the first cylindrical portion 41 from the shaft portion 23 can be relatively reduced. Further, when the connecting member 40 is screwed forward, the connecting member 40 is less likely to come into contact with the peripheral members of the fixture 11.

(4) By using the space forming member 60, it is possible to reliably secure a movement permissible space D that is longer than the first screw length L1, and the fixture 11 can be installed while the movement permissible space D is secured. Therefore, in the installation structure of the fixture 11, it is possible to prevent the occurrence of a problem in which the first screw portion 41a and the first screwed portion 24 cannot be unscrewed. Furthermore, by installing the fixture 11 with the space forming member 60 attached to the second threaded portion 42a, the connecting member 40 will spiral during the installation work of the fixture 11, and the movement permissible space D will be increased. This can prevent the situation from becoming impossible to secure.

(5) By removing the space forming member 60 from the second threaded portion 42a and disposing the regulating portion 62, the connecting member 40 can be moved in the direction of narrowing the movement permissible space D. The space forming member 60 can be attached by fitting the attachment part 61 to the second threaded part 42a, and the space forming member 60 can be easily removed from the second threaded part 42a by removing the fitting. I can do it.

(6) When the space forming member 60 is attached to the second threaded portion 42a, the regulating portion 62 covers the first cylindrical portion 41 from the outer peripheral side, and covers approximately half of the connecting member 40 in the radial direction. Therefore, when operating the moving operating member 50 by screwing it to separate the first adhesive base 20 and the second adhesive base 30, it is possible to prevent the connecting member 40 from being mistakenly operated as the moving operating member 50.

(7) As the connecting member 40 spirals, the second threaded portion 42a enters the inside of the cylindrical portion 33. For example, in the movable operating member 50, the connecting threaded portion 51a is formed on the outer peripheral side of the operating threaded portion 52a, and the movable operating member 50 is formed into a double cylinder shape. Further, a connecting threaded portion 51a is formed on the outer circumferential surface of the outer cylinder portion, and the second threaded portion 42a is female threaded so as to be screwed into this connecting threaded portion 51a. Compared to the case of this configuration, the connecting member 40 can be made smaller in diameter, and the fixture 11 can be made smaller.

(8) In the second base main body 31 of the second adhesive base 30, a space recess 31d is formed in a portion located inside the cylindrical portion 33. By providing this space recess 31d, when the connecting member 40 is screwed, the second screw portion 42a and the second base main body 31 are prevented from interfering, and the screwing of the connecting member 40 is prevented by the second adhesive base 30. The first screw portion 41a and the first screwed portion 24 can be unscrewed without being hindered.

This embodiment can be modified and implemented as follows. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
- The first screw length L1 and the second screw length L2 may be the same, or the first screw length L1 may be longer than the second screw length L2.

In the double-cylindrical shape of the movable operation member 50, the inside and outside of the connection screw portion 51a and the operation screw portion 52a may be interchanged. Specifically, an operating threaded portion 52a is formed on the inner circumferential surface of the inner cylindrical portion 51 to be threaded into the second threaded portion 34, and an operating threaded portion 52a is formed on the outer periphery of the outer cylindrical portion 52 to be threaded into the second threaded portion 42a. A connecting threaded portion 51a is formed. Further, the second screw portion 42a of the connecting member 40 may be configured to be threaded on the outside of the second screwed portion 34.

○ If the tip of the second screw portion 42a does not interfere with the second base main body 31 when the connecting member 40 moves in the direction of narrowing the movement permissible space D, the space recess 31d of the second base main body 31 may not exist. good.

○ The space recess 31d does not need to penetrate the second base main body 31 in the thickness direction. Further, when the bottom surface of the cylindrical portion 33 is located closer to the tip of the cylindrical portion 33 than the back surface 31b of the second base main body 31, the space recess 31d is recessed in the bottom surface of the cylindrical portion 33, and the second It is not necessary to reach the base main body 31.

As shown in FIG. 8 or 9, the first screwed part 24 is provided near the tip of the shaft-like part 23, and the first screwed length L1 is made shorter than in the embodiment. Further, the first threaded portion 41a is provided closer to the base end of the first cylindrical portion 41, thereby reducing the range in which the first threaded portion 41a is provided.

When configured in this way, the amount by which the connecting member 40 is screwed can be made smaller than in the embodiment. Therefore, the first threaded portion 24 and the first threaded portion 41a can be unscrewed more quickly than in the embodiment. Furthermore, by moving the first adhesive base 20 affixed to the fixed object 10 in a direction away from the connecting member 40 along the facing direction Y, the first adhesive base 20 can be separated from the connecting member 40 and fixed. The object 10 can be moved from the floor surface Fa.

○ The first threaded part 24 of the first adhesive base 20 is a female thread formed on the inner peripheral surface of the shaft-shaped part 23, and the first threaded part 41a of the connecting member 40 is formed on the outer peripheral surface of the first cylindrical part 41. It may also be a male thread.

○ As shown in FIG. 10, the fixture 11 may include a separation display means for ensuring a movement permissible space D that is longer than the first screw length L1. The separation display means defines a space in which the connecting member 40 moves toward the second adhesive base 30 as a movement permissible space D until the first screw portion 41a and the first screwed portion 24 are disengaged from each other. In order to ensure this, the distance position of the connecting member 40 from the second adhesive base 30 is displayed. The separation display means is, for example, a ruler 70. The ruler 70 is provided with a first display 70a and a second display 70b for indicating the dimensions of the movement permissible space D in the facing direction Y. Then, the outer surface of the disc portion 43 is aligned with the first marking 70a of the ruler 70, and the outer surface of the connecting portion 53 is aligned with the second marking 70b of the ruler 70, thereby securing the movement permissible space D.

In this case, the movement permissible space D can be secured without using the space forming member 60, but the ruler 70 and the space forming member 60 may be used together.
○ As shown in FIG. 11, the fixture 11 has a display indicating that the connecting member 40 has moved away from the second adhesive base 30 in order to secure a movement permissible space D that is longer than the first screw length L1. It may be provided with means. The display means secures a space, as a movement permissible space D, for the connecting member 40 to move toward the second adhesive base 30 until the first threaded part 41a and the first threaded part 24 are unscrewed. This indicates that the connecting member 40 has separated from the second adhesive base 30 in order to The display means is, for example, a mark 42b provided on the outer peripheral surface of the second threaded portion 42a. With the first threaded part 41a screwed into the first threaded part 24 and positioned at the first threaded position R1, from the outer surface of the disc part 43 of the outer peripheral surface of the second threaded part 42a, A mark 42b is provided at a position spaced apart by the dimension of the movement permissible space D in the direction Y. In this case, the movement permissible space D can be secured without using the space forming member 60, but the mark 42b and the space forming member 60 may be used together.

○ The space forming member 60 may include only the attachment portion 61.
The covering portion 62b of the regulating portion 62 does not need to cover the entire first threaded portion 41a in the axial direction from the outside, and may cover a part of the first threaded portion 41a in the axial direction from the outside.

The attachment portion 61 of the space forming member 60 may be attached to the movement operation member 50. For example, the attachment portion 61 may be attached to the outer peripheral surface of the outer cylinder portion 52 of the moving operation member 50.
○ The shapes of the first base body 21 and the second base body 31 may be changed as appropriate. For example, the first base main body 21 and the second base main body 31 may have a disc shape, a pentagonal plate shape, or a hexagonal plate shape.

○ Instead of a single adhesive mat, a plurality of adhesive mats may be adhered to the first mat adhesion surface 21a of the first base main body 21; Instead of a single adhesive mat, a plurality of divided adhesive mats may be adhered to the two-mat adhesive surface 31a.

○ The shape of the first mat adhering surface 21a and the shape of the first adhesive mat 22 do not have to match. For example, while the first mat adhering surface 21a is rectangular in shape, the first adhesive mat 22 may have an elliptical shape. Similarly, the shape of the second mat sticking surface 31a and the shape of the second adhesive mat 32 do not need to match.

○ The moving operation member 50 has a shape in which the inner cylinder part 51 and the outer cylinder part 52 do not overlap in the radial direction of the movement operation member 50, and the inner cylinder part 51 and the outer cylinder part 52 do not overlap in the axial direction of the movement operation member 50. The shapes may be arranged side by side.

○ In the first adhesive base 20, the shaft-like part 23 of the first base body 21 is removed, and a female thread is formed that is recessed from the back surface 21b of the first base body 21. This is the first screwed part provided on the back surface 21b of the base main body 21. Further, in the connecting member 40, a male thread may be formed on the outer peripheral surface of the first cylindrical portion 41, and this male thread may be used as the first threaded portion 41a.

In addition, in the second adhesive base 30, the cylindrical portion 33 of the second base body 31 is removed, and a female thread is formed that is recessed from the back surface 31b of the second base body 31. This is the second screwed part provided on the back surface 31b of the second base main body 31. Further, in the moving operation member 50, a male thread may be formed on the outer peripheral surface of the outer cylinder portion 52, and this male thread may be used as the operating thread portion 52a.

If the object 10 to be fixed is a refrigerator or a chest of drawers, the fixture 11 is attached to the lower surface of the ceiling and the upper surface of the refrigerator or chest of drawers. In this case, the lower surface of the ceiling and the upper surface of the refrigerator or chest of drawers are the opposing surfaces to be adhered.
