Description

  The present invention relates to a push screw tool, and more specifically, when an object to be attached such as an end of a glass door is inserted into a frame and attached, the screw is inserted into a screw hole formed in the frame, The present invention relates to a push screw tool that fixes and attaches the attached body to the inside of the frame while pressing against the attached body such as an end of a glass door inserted into the frame.

  In general, a commodity display case or the like is provided with an openable and closable glass door, and such a glass door is inserted into a receiving metal fitting that is a substantially U-shaped frame. As an application showing such a glass door mounting structure, for example, there is an application as shown in Patent Document 1 below.

  In the glass door mounting structure as shown in Patent Document 1, a screw hole 13c is previously drilled in a substantially U-shaped frame body 12c as shown in FIG. 35, and the end of the glass door is formed in the frame body 12c. And a fastening screw 25 as shown in FIG. 5A is inserted into the screw hole 13c from the outside of the frame body 12c, and the tip of the fastening screw 25 is inserted. The glass door was fixed in the frame 12c by pressing against the glass door. Such a fastening screw 25 causes the glass door to act by applying a pressing force to the glass door, which is a mounted body, by a rotational movement when the fastening screw 25 is screwed into the screw hole 13c of the glass door. It is to be fixed.

  However, such a tightening screw is generally made of metal, hard synthetic resin, or the like, and the glass door as the mounted body is also made of hard material glass, so the tightening screw is placed in the screw hole 13c. By rotating for screw insertion, the contact surface between the tip of the tightening screw and the glass door is likely to slip, and the pressing force due to the rotational movement of the tightening screw effectively acts on the glass door that is the attachment body. There was a problem of not doing.

  In addition, since the fastening screw and the glass door as the mounted body are both made of a hard material, the glass door may break when a pressing force is generated by the rotational movement of the fastening screw.

  Therefore, in order to prevent such sliding of the contact surface between the clamping screw and the glass door and cracking of the glass door, a rubber piece 26 is provided at the tip of the clamping screw 25 as shown in FIG. However, since the tightening screw as described above applies a pressing force due to rotational movement to the glass door, the friction resistance is reduced when the tightening screw is rotationally pressure-bonded to the glass door. A problem has arisen in that a twisting force is generated in the rubber piece 26 made of a large material, and the rubber piece 26 may be inadvertently detached from the tip of the fastening screw 25.

  Therefore, in order to solve such a problem, for example, as shown in FIG. 36, a separate interposed member 27 in which a plate-like rubber piece (not shown) is attached to a metal plate is attached to the attached body. It is also carried out between a certain glass door and a frame. However, in this case, the interposition member 27 must be prepared separately, which not only increases the number of parts, but also interposes such an interposition member 27 at a desired position between the glass door and the frame. The work to make was complicated.

  In addition, since the tightening screw as described above exerts a pressing force due to the rotational motion, when directly acting on the glass door as the mounted body, it still acts indirectly on the glass door via the interposing member 27. If this is done, the pressing force due to the rotation may be reduced.

Utility Model Registration No. 2531948

  The present invention has been made in order to solve the above-mentioned problems. Like the conventional push screw tool, the present invention is rotationally pressure-bonded to an object to be attached such as a glass door so as to reduce the frictional resistance of a rubber piece or the like. It does not cause torsional force to a large member and removes a member such as a rubber piece from the push screw tool, and the pressing force works effectively with the attached object such as a glass door inserted in the frame. It is an object of the present invention to provide a push screw tool that can be suitably fixed and attached.

  The present invention has been made to solve such a problem, and a pressing attachment in which a connecting portion is formed on one end side and a pressing portion capable of pressing the attached body is formed on the other end side. 1 and a rotary attachment 2 having a coupling portion that can be coupled to the coupling portion of the pressing attachment 1 on the inner peripheral surface and a male screw 11 that can be screwed to the female screw 14 of the mounting portion of the mounted body on the outer peripheral surface. The connecting part of the rotating attachment 2 is connected to the connecting part of the pressing attachment 1, and the rotating attachment 2 is threadedly engaged with the female screw 14 of the attaching part of the mounted body while the male screw 11 on the outer peripheral surface of the rotating attachment 2 is screwed. 2, the pressing attachment 1 and the rotating attachment 2 come into contact with each other at a portion facing each other, and the pressing attachment 1 and the rotating attachment are in contact with each other. The push screw tool is configured so that the rotational force of the rotary attachment 2 can act as a pressing force in the straight direction with respect to the attached body of the pressing attachment 1 in a state in which the rotating attachment 2 is in contact. Is to provide.

The coupling portion on one end side of the pressing attachment 1 is, for example, a male screw 6, and the coupling portion of the rotary attachment 2 is, for example, a female screw 9 that can be screwed to the male screw 6 of the pressing attachment 1. The pressure attachment 1 can be moved together with the rotation attachment 2 by rotating the rotation attachment 2 while screwing the female screw 9 of the rotation attachment 2 into the male screw 6 of the pressure attachment 1, and the pressure attachment 1. When the screwed state of the male screw 6 and the female screw 9 of the rotary attachment 2 is released, the pressing attachment 1 and the rotary attachment 2 come into contact with each other at the portions facing each other, and in such a contact state, the rotary attachment The rotational force of the rotary attachment 2 when rotating the male screw 11 on the outer peripheral surface 2 while being engaged with the female screw 14 of the attachment portion of the attachment body acts as a pressing force of the pressing attachment 1 in the straight direction with respect to the attachment body. It will be configured as possible.
The present invention can also be applied to coupling parts other than the coupling parts such as the male screw 6 of the pressing attachment 1 and the female screw 9 of the rotary attachment 2. For example, this is a case where the outer peripheral surface of the pressing attachment 1 and the rotary attachment 2 are simply fitted.
Here, the “joining portion” in the present invention does not only mean that the pressing attachment 1 and the rotary attachment 2 are joined in a state where they are not detached from each other, but loosely joined so that they can be easily detached. It also includes the state that has been done.
The point is that the pressing attachment 1 and the rotating attachment 2 need only be coupled so that the rotational force of the rotating attachment 2 can act as a pressing force in the straight direction of the pressing attachment 1 against the attached body.

As described above, when the pressing attachment 1 and the rotary attachment 2 are in contact with each other, the contact is preferably a point contact state.
As a specific configuration that contacts at the portions facing each other, for example, the tip portion on one end side of the pressure attachment 1 and the inner peripheral surface of the rotary attachment 2 are configured to face each other and contact each other.
Note that “the pressing attachment 1 and the rotating attachment 2 are in contact with each other” means that the pressing attachment 1 and the rotating attachment 2 are in direct contact with each other, for example, via a washer. This includes cases where the user is doing.
The pressing attachment 1 and the rotating attachment 2 are materials having a low frictional resistance to the extent that the pressing attachment 1 does not rotate due to the rotation of the rotating attachment 2 when the pressing attachment 1 and the rotating attachment 2 come into contact with each other. It is desirable to consist of Examples of such a material having low frictional resistance include metals and hard synthetic resins.

It is desirable to adhere a contact surface plate 7 having elasticity on the surface side of the pressing portion 1 of the pressing attachment 1 that contacts the attached body.
As the pressing attachment 1, for example, a head portion 3 that functions as a pressing portion that can press the attached body, a body portion 4 that is connected to the head portion 3, and a distal end side of the body portion 4. It is possible to use a structure in which a joint portion is formed on the outer peripheral surface of the tip portion 5.
As the rotary attachment 2, for example, an opening 19 is formed on one end surface 18 thereof, and the first space 8 is formed in communication with the opening 19, and is communicated with the first space 8. A second space portion 10 is formed, and an internal thread 9 that can be screwed into the external thread 6 of the pressure attachment 1 is formed on the inner peripheral surface of the first space portion 8. A female screw is not formed, and the pressure attachment 1 may be formed so as to have a size that can accommodate the entire portion of the pressing attachment 1 where the male screw 6 is formed. In this case, the inner diameter of the second space 10 is formed larger than the outer diameter of the male screw 6 of the pressing attachment 1.

Since the present invention is configured as described above, the male screw on the outer peripheral surface of the rotating attachment is screwed into the female screw on the mounting portion of the mounted body, so that when the rotating attachment is rotated, the rotation The rotational force of the attachment is converted into a pressing force in the straight direction in which the pressing attachment presses the attached body.
In particular, the coupling portion on one end side of the pressure attachment is a male screw, and the coupling portion of the rotary attachment is a female screw that can be screwed to the male screw of the pressure attachment, and is pressed when the screwed state of the male screw and the female screw is released. When the attachment 1 and the rotary attachment 2 are in contact with each other at a portion facing each other and the pressing force in the straight direction of the pressing attachment acts, the male screw of the initial pressing attachment and the female screw of the rotating attachment are screwed together. However, when the screwed state is released, the pressing attachment does not rotate. Therefore, when the rotating attachment is rotated, the rotational force of the rotating attachment does not rotate the pressing attachment. Therefore, the pressure is preferably converted into a pressing force in a straight direction in which the pressure is pressed.

  And since a pressing attachment presses a to-be-attached body with the pressing force of such a straight advance direction, the pressing force acts on a to-be-attached body suitably, and the to-be-attached body can be fixed and attached reliably. There is.

  In addition, even when a contact surface plate such as rubber is attached to the contact surface side of the pressing attachment with the mounted body, the pressing attachment presses the mounted body with the pressing force in the straight direction. There is no effect of twisting or the like, and the contact surface plate is not accidentally detached from the pressing attachment.

As described above, the push screw tool of the present invention includes a pressing attachment in which a coupling portion is formed on one end side and a pressing portion capable of pressing the attached body is formed on the other end side, and the pressing attachment. A rotating attachment having an outer peripheral surface having a male screw that can be screwed into a female screw of the mounting portion of the mounted body, and a connecting portion that can be connected to the connecting portion of the mounting body. The pressure attachment 1 and the rotation attachment 2 are coupled by rotating the rotation attachment while being coupled to the coupling portion of the pressure attachment and screwing the male screw on the outer peripheral surface of the rotation attachment to the female screw of the attachment portion of the attachment body. Are in contact with each other, and in the state where the pressing attachment 1 and the rotating attachment 2 are in contact with each other, the rotating attachment Rotational force of, those which are constituted as to be able to act as a pressing force of the rectilinear direction with respect to the mounting member of the pressing attachment.
The coupling portion on one end side of the pressing attachment is formed by, for example, a male screw, and the coupling portion of the rotary attachment is formed by, for example, a female screw that can be screwed into the male screw of the pressing attachment. By rotating the rotary attachment while screwing the female screw of the rotary attachment to the male screw of the press attachment, the press attachment 1 can move together with the rotary attachment 2, and the male screw of the press attachment and the rotary attachment When the screwed state with the female screw is released, the pressing attachment 1 and the rotating attachment 2 come into contact with each other and the rotating attachment 2 is in contact with the pressing attachment 1 and the rotating attachment 2. The rotational force of the rotation attachment when rotating the male screw on the outer peripheral surface of the attachment body while being screwed into the female screw of the attachment portion of the attachment body can act as a pressing force in the straight direction with respect to the attachment body of the pressing attachment. Will be.

As described above, the pressing attachment and the rotating attachment come into contact with each other at the portions facing each other. In this case, it is desirable that the pressing attachment 1 and the rotating attachment 2 are configured to contact in a point contact state. .
As a specific configuration that contacts at the portions facing each other, for example, the tip portion on one end side of the pressure attachment 1 and the inner peripheral surface of the rotary attachment 2 are configured to face each other and contact each other.
Further, “the pressing attachment 1 and the rotating attachment 2 are in contact with each other” means that the pressing attachment 1 and the rotating attachment 2 are in direct contact with each other, for example, via a washer. This includes cases where the user is doing.
The material of the pressure attachment or the rotation attachment is not particularly limited. However, when the pressure attachment 1 and the rotation attachment 2 come into contact with each other, the rotation of the rotation attachment 2 causes the rotation of the pressure attachment 1 together. It is desirable to be made of a material with a low frictional resistance. Examples of such a material having low frictional resistance include metals and hard synthetic resins. As the metal, for example, brass, zinc, steel, or the like can be used.

Furthermore, the contact surface plate can be attached to the pressing attachment on the surface side of the pressing portion that contacts the attached body.
Since the pressing attachment is made of metal, hard synthetic resin, or the like as described above, the pressing portion of the pressing attachment is attached by attaching the contact surface plate to the pressing portion of the pressing attachment as described above. Therefore, it is possible to prevent the attached body from being damaged, and the like. As the material for the contact surface plate, rubber, synthetic resin, or the like can be used. This contact surface plate can suitably prevent damage to the mounted body as described above by forming a contact surface with the mounted body, but as a function of this contact surface plate, It is an even more important property that the frictional resistance is large by coming into contact with the mounted body and the pressing attachment. This point will be described later.

The configuration of the pressure attachment is not particularly limited, but for example, a head that functions as a pressing portion that can press the attached body, a trunk that is connected to the head, and a distal end side of the trunk It is possible to use the one having a distal end portion that is continuously provided on the outer peripheral surface and having an external thread formed on the outer peripheral surface of the distal end portion. In this case, the outer diameter of the head of the pressure attachment can be formed larger than the outer diameter of the rotary attachment. This is because the pressing force of the head of the pressing attachment against the attached body can be applied more suitably. As a result, the outer diameter of the head of the pressure attachment can be formed larger than the outer diameter of the trunk or the tip. Thus, by forming the outer diameter of the head larger than the outer diameter of the body part or the tip part, the side surface shape of the pressure attachment is substantially T-shaped.
On the other hand, the outer diameter of the head of the pressure attachment can be formed smaller than the outer diameter of the rotary attachment, more specifically, the outer diameter of the outer thread of the rotary attachment. In other words, it can be formed smaller than the inner diameter of the mounting portion (insertion hole) of the mounted body in which the female screw is formed. By forming the outer diameter of the head of the pressure attachment to be smaller than the inner diameter of the insertion hole of the mounted body, the entire pressure attachment can be inserted into the insertion hole of the mounted body. Since it can be inserted not only from the inside of the body to be mounted, but also from the outside, the male screw at the tip of the pressing attachment is screwed with the female screw of the rotating attachment in advance so that the pressing attachment and the rotating attachment are combined. Then, the external thread on the outer peripheral surface of the rotary attachment can be screwed into the internal thread of the mounting portion of the mounted body.
Moreover, although the whole shape of a press attachment is not specifically limited, For example, it forms in a substantially cylindrical shape.

  Further, the configuration of the rotary attachment is not particularly limited. For example, an opening is formed on one end surface thereof, and a first space is formed in communication with the opening, and the first space is formed. A second space is formed, an internal thread of the first space is formed with an internal thread that can be screwed into an external thread of the pressing attachment, and an internal thread of the second space is formed with an internal thread. It is not formed, and the press attachment 1 having a size that can accommodate the entire portion where the male screw is formed can be used.

  In this case, the inner diameter of the second space is formed larger than the outer diameter of the head of the pressure attachment. Further, the shape of the rotation attachment is not particularly limited, but for example, the rotation attachment is formed so as to be substantially cylindrical.

  As a configuration that enables the attached body to be pressed on the other end side of the pressing portion of the pressing attachment, for example, a state where the surface opposite to the pressing portion of the attached body of the pressing attachment and the inner peripheral bottom surface of the rotating attachment are in contact with each other And it can comprise so that the press part of the said press attachment can press a to-be-attached body by rotation of a rotation attachment. The pressing attachment is composed of the head, the trunk, and the tip as described above, and the rotating attachment is formed having the first space and the second space as described above, and the second When the space portion is formed in a concave shape, the tip surface of the tip portion of the pressing attachment comes into contact with the inner peripheral bottom surface of the second space portion of the rotary attachment. In this case, the front end surface of the front end of the pressure attachment is formed in a curved shape that protrudes outward, so that the front end surface of the press attachment and the inner peripheral bottom surface of the second space portion of the rotary attachment are in point contact. It is possible to prevent the resistance at the time of contact from becoming unnecessarily large, and the action of converting the rotational force of the rotary attachment to the pressing force in the straight direction with respect to the attached body of the pressure attachment is preferably generated. Become.

  On the other hand, in a state where the surface opposite to the pressing portion of the attached body of the pressing attachment is in contact with the end surface of the opening of the rotating attachment, the pressing portion of the pressing attachment presses the attached body by the rotation of the rotating attachment. It can also be configured. The pressing attachment is composed of the head, the trunk, and the tip as described above, and the rotating attachment is formed having the first space and the second space as described above, and the second When the space is formed in a concave shape, the tip surface of the tip of the pressure attachment does not contact the inner peripheral bottom surface of the second space of the rotation attachment, and the head of the pressure attachment and the opening of the rotation attachment The end face 18 of 19 contacts, and the head of a press attachment presses a to-be-attached body. In this case, the second space may be formed in a concave shape, but it is also possible to adopt a configuration in which an opening is formed on the other end face side of the rotary attachment instead of such a concave shape. It is.

Hereinafter, more specific embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
As shown in FIG. 1, the push screw tool of this embodiment includes a press attachment 1 and a rotary attachment 2.

  The pressing attachment 1 includes a substantially disc-shaped head portion 3 that functions as a pressing portion that presses the attached body, and a substantially cylindrical body portion 4, and the outer peripheral surface of the distal end portion 5 on the distal end side of the body portion 4. As shown in FIG. 1, a male screw 6 is formed. In addition, the front end surface 5a of the front end portion 5 is formed in a curved shape that protrudes outward in the present embodiment. However, it can also be formed as a face. As shown in the figure, the pressing attachment 1 has a substantially T-shaped side surface, and the entire head 3, body 4, and tip 5 are made of metal such as brass, zinc, steel, or the like. It is made of hard synthetic resin.

  Of the front and back surfaces of the head 3 of the pressure attachment 1, a contact surface with the mounted body is formed on the surface opposite to the surface on which the body 4 is connected, that is, on the surface side of the head 3. Then, a contact surface plate 7 made of rubber or elastic synthetic resin that causes frictional resistance at the time of contact is attached.

  The rotation attachment 2 is formed in a substantially cylindrical shape as a whole, and is made of a metal such as brass, zinc, or steel, or a hard synthetic resin, similarly to the press attachment 1. An opening 19 is formed on one end surface 18 of the rotary attachment 2, and a relatively shallow first space 8 is formed in communication with the opening 19. On the inner peripheral surface of the first space portion 8, a female screw 9 is formed which can be screwed into the male screw 6 formed on the outer peripheral surface of the distal end portion 5 of the pressing attachment 1.

  In addition, a concave second space portion 10 is formed inside the rotary attachment 2 so as to communicate with the first space portion 8 and on the side opposite to the opening portion 19. Since the second space portion 10 is formed in a concave shape, no opening is formed on the other end surface 20 of the rotary attachment 2 on the side opposite to the opening 19. Unlike the first space 8, no internal thread is formed on the inner peripheral surface of the second space 10.

  Further, the second space portion 10 is formed with a depth dimension that can accommodate the distal end portion 5 of the pressing attachment 1. That is, when the male screw 6 on the outer peripheral surface of the distal end portion 5 of the pressing attachment 1 is screwed with the female screw 9 on the inner peripheral surface of the first space portion 8 of the rotary attachment 2 and the rotary attachment 2 is further rotated, The depth dimension of the second space portion 10 is set so that the screwed state is released and the distal end portion 5 of the pressing attachment 1 can be accommodated in the second space portion 10 of the rotary attachment 2.

  On the other hand, the inner diameter of the second space portion 10 is formed larger than the outer diameter of the distal end portion 5 of the pressing attachment 1. This is because when the male screw 6 of the distal end portion 5 of the pressing attachment 1 is released from the screwed state with the female screw 9 of the first space portion 8 of the rotating attachment 2, the distal end portion 5 of the pressing attachment 1 becomes the rotational attachment 2. This is so that it can be inserted into the second space portion 10.

Furthermore, a male screw 11 is formed on the outer peripheral surface of the rotary attachment 2. Here, as shown in FIG. 1, the male screw 11 can be partially formed on the outer peripheral surface of the rotary attachment 2 in addition to being formed on the entire outer peripheral surface of the rotary attachment 2.
Further, as shown in FIG. 2, a groove 22 is formed on the outer end surface 20 of the rotary attachment 2. The groove portion 22 is for engaging a separate attachment for rotating the rotary attachment 2 so that the operation can be easily performed when the rotary attachment 2 is rotated.
Furthermore, the outer diameter of the head of the pressure attachment 1 is formed larger than the outer diameter of the rotary attachment 2.

  Next, the case where the glass door which is a to-be-attached body is attached in a frame using the press screw tool which consists of the above press attachments 1 and the rotation attachment 2 is demonstrated.

  First, as shown in FIGS. 3 and 4, a frame body 12 having a substantially U-shaped cross section for inserting an end portion of a glass door 15 that is an attached body is prepared. As shown in the figure, the frame body 12 is not provided with a hole on the one piece 12a side, but on the other piece 12b side is a hole 13 for inserting the push screw tool of the present embodiment. It has been drilled. A female screw 14 that can be screwed into a male screw 11 formed on the outer peripheral surface of the rotary attachment 2 is formed on the inner peripheral surface of the hole 13.

  Next, as shown in FIG. 5, the pressing attachment 1 is grasped with a finger or the like and inserted into the hole 13 of the frame 12. Specifically, as shown in the direction of arrow A in FIG. 5, the body 4 of the press attachment 1 is inserted into the hole 13 of the frame 12, and the head 3 of the press attachment 1 is connected to the other piece 12 b of the frame 12. It is made to contact with the inner surface side. In this state, the distal end portion 5 of the pressing attachment 1 is bare from the hole 13 to the outside of the other piece 12b of the frame 12 as shown in FIG. 5, so that the rotary attachment 2 is easily screwed.

  Next, as shown in FIG. 6, the female screw 9 on the inner peripheral surface of the first space portion 8 of the rotary attachment 2 is screwed with the male screw 6 of the distal end portion 5 of the pressing attachment 1, so that the rotary attachment 2 is tightened. When rotating, the rotation attachment 2 gradually moves in the direction of arrow B in FIG. Then, when the rotary attachment 2 is further rotated in the tightening direction, the male screw 11 on the outer peripheral surface of the rotary attachment 2 and the female screw 14 on the inner peripheral surface of the hole 13 of the frame body 12 are screwed together.

  In this case, it is easy to screw the female screw 9 of the rotary attachment 2 into the male screw 6 of the distal end portion 5 of the pressing attachment 1, and a glass door 15, which will be described later, is easily inserted into the frame body 12. In order to obtain a state, it is desirable that the head 3 of the pressing attachment 1 is pressed with a finger or the like and brought into contact with the inner surface side of the other piece 12b of the frame body 12 to be positioned. Then, the female screw 9 of the rotary attachment 2 is screwed to the male screw 6 of the distal end portion 5 of the pressing attachment 1 to a certain position, and further, the male screw 11 of the rotary attachment 2 and the female screw 14 on the inner peripheral surface of the hole 13 of the frame body 12. And the head 3 of the pressing attachment 1 is positioned in contact with the inner surface side of the other piece 12b of the frame body 12 without being particularly pressed by a finger or the like.

  As described above, it is also possible to insert the rotary attachment 2 into the hole 13 of the frame body 12 first without inserting the pressing attachment 1 into the hole 13 of the frame body 12 first. In this case, the rotary attachment 2 is positioned in the hole 13 of the frame 12 by screwing the male screw 11 on the outer peripheral surface of the rotary attachment 2 with the female screw 14 on the inner peripheral surface of the hole 13 of the frame 12. It is easy to keep.

  Next, as shown in the direction of the arrow C in FIG. The end of the glass door 15 is inserted into the frame 12 so as to be close to the one piece 12a side of the frame 12. Specifically, a rubber contact surface plate 16 is prepared, and the contact surface plate 16 is interposed between the piece 12a of the frame 12 and the end of the glass door 15, and the contact surface The end of the glass door 15 is indirectly brought into contact with the one piece 12a of the frame body 12 through the plate 16 for use.

  In this case, the female screw 9 of the rotary attachment 2 is screwed to the male screw 6 of the distal end portion 5 of the pressing attachment 1 to a certain position, and the head 3 of the pressing attachment 1 is brought into contact with the inner surface side of the other piece 12b of the frame 12. Since it is positioned in contact, when inserting into the frame 12 so that the end of the glass door 15 indirectly contacts the piece 12a of the frame 12 through the contact surface plate 16, As shown in FIG. 7, there is a gap 17. Therefore, when the end of the glass door 15 is inserted into the frame body 12, the head 3 of the pressing attachment 1 does not become an obstacle.

After the end portion of the glass door 15 is inserted into the frame body 12 in this way, when the rotary attachment 2 is further rotated in the tightening direction, the male screw 6 of the distal end portion 5 of the pressing attachment 1 is changed to the female screw 9 of the rotary attachment 2. , The rotary attachment 2 further moves in the direction toward the glass door 15, that is, in the direction indicated by the arrow D in FIG. 8, and accordingly, the pressing attachment 1 moves in the direction indicated by the arrow E in FIG. As shown in the figure, the head 3 of the pressing attachment 1 comes into contact with the glass door 15 via the contact surface plate 7.
After the head 3 of the pressing attachment 1 comes into contact with the glass door 15 via the contact surface plate 7, when the rotation attachment 2 is further rotated, only the rotation attachment 2 further moves in the direction of the arrow D. In this case, since the male screw 6 at the distal end portion 5 of the pressing attachment 1 is still screwed with the female screw 9 of the rotating attachment 2, a force to rotate the pressing attachment 1 as the rotating attachment 2 rotates. Works.
However, when the head 3 of the pressure attachment 1 is in contact with the glass door 15 via the contact surface plate 7, the frictional resistance at the contact portion between the contact surface plate 7 and the glass door 15 is large. The rotation of the pressure attachment 1 is blocked by the resistance, and only the rotation attachment 2 moves while rotating.
That is, in the present embodiment, as in the prior art, the pressing screw 1 with the rubber contact surface plate attached is not directly gripped and rotationally pressure-bonded, but the pressing attachment 1 and the rotational attachment 2 The female screw 9 of the rotary attachment 2 is screwed into the male screw 6 of the pressing attachment 1 using a push screw tool made of a member, and the male screw 11 on the outer peripheral surface of the rotary attachment 2 and the female screw on the inner peripheral surface of the hole 13 of the frame 12 are used. 14 is also screwed, that is, there are two screwing points. Therefore, even if the rotary attachment 2 is rotated, it is pressed by the frictional resistance at the contact part between the contact surface plate 7 and the glass door 15 as described above. Since the attachment 1 is prevented from rotating, and therefore, the pressing attachment 1 does not rotate, a twisting force is generated on the contact surface plate 7. It is not even a Unako.

  After the head 3 of the pressure attachment 1 contacts the glass door 15 via the contact surface plate 7, the rotation attachment 2 is further rotated, and when the rotation attachment 2 moves a predetermined distance in the direction of the arrow D in FIG. The screwed state of the male screw 6 of 1 and the female screw 9 of the rotary attachment 2 is released, and the distal end portion 5 of the pressing attachment 1 enters the second space portion 10 of the rotary attachment 2 and is stored in the second space portion 10. Will be.

  After the distal end portion 5 of the pressing attachment 1 is housed in the second space portion 10 of the rotary attachment 2 in this way, when the rotary attachment 2 is further rotated in the tightening direction, the male screw 11 on the outer peripheral surface of the rotary attachment 2 and The rotary attachment 2 moves in the direction toward the glass door 15, that is, in the direction of the arrow in FIG. 9, due to the screwed state of the inner peripheral surface of the hole 13 of the frame 12 with the female screw 14.

When the distal end surface 5a of the distal end portion 5 of the pressing attachment 1 comes into contact with the inner peripheral bottom surface 10a of the second space portion 10 of the rotary attachment 2, further movement of the rotary attachment 2 in the direction of the arrow is prohibited. The Rukoto. However, as will be described later, the rotary attachment 2 is finally rotated and tightened, so that the contact surface plate 7 slightly contracts, and the rotary attachment 2 slightly moves by the amount of contraction of the contact surface plate 7. .
Further, in this case, since the distal end surface 5a of the distal end portion 5 of the pressing attachment 1 is formed in a curved shape that slightly protrudes outward as described above, the distal end surface 5a of the pressing attachment 1 and Point contact with the inner peripheral bottom surface 10a of the second space portion 10 of the rotary attachment 2 can prevent the resistance during contact from becoming unnecessarily large.

  Then, when the distal end surface 5a of the distal end portion 5 of the pressing attachment 1 is in contact with the inner peripheral bottom surface 10a of the second space portion 10 of the rotating attachment 2, the rotating attachment 2 is finally rotated and tightened. The head 3 presses the glass door 15 via the contact surface plate 7, whereby the glass door 15 is fixed in the frame 12.

In this case, the rotary attachment 2 is rotated by the male screw 11 on the outer peripheral surface thereof being screwed into the female screw 14 on the inner peripheral surface of the hole 13 of the frame body 12, but the inner surface of the rotary attachment 2 is rotated. Since the female screw 9 and the male screw 6 on the outer peripheral surface of the pressing attachment 1 are not screwed together, the pressing attachment 1 does not rotate. Therefore, the distal end surface 5a of the pressing attachment 1 is in contact with the inner peripheral bottom surface 10a of the rotating attachment 2. When the rotary attachment 2 is rotated in the contacted state, the rotational force of the attachment 2 is converted to a pressing force in the straight direction in which the pressing attachment 1 presses the glass door 15 without rotating.
Further, in this case, since the distal end surface 5a of the pressing attachment 1 and the inner peripheral bottom surface 10a of the rotating attachment 2 are in a point contact state, the rotational force of the attachment 2 is a pressing force in the straight direction of the pressing attachment 1. Will be converted efficiently.
Further, in this case, since the pressing attachment 1 and the rotating attachment 2 are made of a material having a smooth surface such as metal or hard synthetic resin as described above, the front end surface 5a of the pressing attachment 1 is rotated. In a state in which the attachment 2 is in contact with the inner peripheral bottom surface 10a, the frictional resistance hardly occurs on the contact surfaces of both. On the other hand, the contact surface plate 7 adhered to the head 3 of the pressure attachment 1 is made of a material such as rubber having a high frictional resistance, and therefore, between the contact surface plate 7 and the glass door 15. High frictional resistance. Therefore, due to the difference in the frictional resistance between the contact surface plate 7 and the glass door 15 and the frictional resistance between the distal end surface 5a of the pressing attachment 1 and the inner peripheral bottom surface 10a of the rotary attachment 2, Even if the rotation attachment 2 rotates, the pressing attachment 1 does not rotate. As a result, the action converted into the pressing force in the straight direction of the pressing attachment 1 is smoothly generated by the rotational force of the attachment 2.

  On the other hand, the contact surface plate 7 made of a material having a high frictional resistance is disposed between the pressure attachment 1 made of a material having a low frictional resistance, such as a metal or a hard synthetic resin, and the glass door 15 made of glass having a low frictional resistance. Since the pressing attachment 1 presses the glass door 15 through the contact surface plate 7 with the pressing force in the straight traveling direction, a force such as twisting acts on the intervening contact surface plate 7. Therefore, the contact surface plate 7 is not inadvertently detached from the head 3 of the pressing attachment 1.

(Embodiment 2)
In this embodiment, the outer diameter of the head of the pressure attachment 1 is formed smaller than the outer diameter of the rotary attachment 2, more specifically, the diameter of the valley portion of the male screw 11 on the outer peripheral surface of the rotary attachment, In that respect, the outer diameter of the head of the pressure attachment 1 is different from that of the first embodiment in which the outer diameter of the rotary attachment 2 is formed.

  Since the outer diameter of the head of the pressure attachment 1 is formed smaller than the diameter of the valley portion of the male screw 11 of the rotary attachment 2, as a result, the outer diameter of the head of the pressure attachment 1 is the frame 12. It becomes smaller than the inner diameter of the hole 13, and the entire pressing attachment 1 can be inserted into the hole 13 of the frame 12 as will be described later.

  However, the basic configuration of the push screw tool composed of the pressing attachment 1 and the rotating attachment 2 is common to the first embodiment. That is, also in the present embodiment, as shown in FIG. 10, the pressing attachment 1 is composed of a head portion 3, a trunk portion 4, and a tip portion 5, a male screw 6 is formed on the outer peripheral surface of the tip portion 5, A contact surface plate 7 is adhered to the surface of the head 3 on the opposite side to the continuous surface. Further, the rotary attachment 2 is formed with a first space portion 8 having a female screw 9 and a second space portion 10 communicating with the first space portion 8, and a male screw 11 is formed on the outer peripheral surface. Further, although not shown, the groove 22 is formed on the outer end surface 20 of the rotary attachment 2 in common with the first embodiment.

  In the present embodiment, as described above, the outer diameter of the head of the pressure attachment is formed to be smaller than the diameter of the valley portion of the male screw 11 of the rotary attachment, and as a result, smaller than the inner diameter of the hole 13 of the frame 12. As a result, the entire pressing attachment 1 can be inserted into the hole 13 of the frame body 12, and the pressing attachment 1 can be inserted not only from the inside of the hole 13 of the frame body 12, but also from the outside. Therefore, it is possible to insert the pressing attachment 1 and the rotary attachment 2 in advance into the hole 13 of the frame 12 from the outside after combining them in advance.

Therefore, first, when the male screw 6 of the distal end portion 5 of the pressing attachment 1 is screwed into the female screw 9 of the rotating attachment 2 and the rotating attachment 2 continues to rotate in the tightening direction, the rotating attachment 2 becomes the head 3 of the pressing attachment 1. As shown in FIG. 11, the screwed state of the male screw 6 of the pressing attachment 1 and the female screw 9 of the rotating attachment 2 is released, and the distal end portion 5 of the pressing attachment 1 is the second space portion of the rotating attachment 2. 10 enters and is accommodated in the second space 10.
In this way, the pressure attachment 1 and the rotary attachment 2 are combined without being separated from each other. Then, as shown in FIG. 12, the pressing attachment 1 and the rotary attachment 2 are combined and inserted into the hole 13 of the frame body 12, and the male screw 11 on the outer peripheral surface of the rotary attachment 2 is inserted into the frame body 12. And screwed into the female screw 14 on the inner peripheral surface of the hole 13.

  With the press attachment 1 and the rotation attachment 2 combined in this way inserted into the hole 13 of the frame body 12, the end of the glass door 15 is inserted into the frame body 12 as shown in FIG. 13. The rubber contact surface plate 16 is interposed between the piece 12 a of the frame 12 and the end of the glass door 15, and the end of the glass door 15 is indirectly connected through the contact surface plate 16. In addition, the point of contact with one piece 12a of the frame body 12 is the same as in the first embodiment.

  In this way, the pressing attachment 1 and the rotating attachment 2 are inserted into the hole 13 of the frame body 12, and the end of the glass door 15 is inserted into the frame body 12. When rotating for tightening, the rotary attachment 2 moves to the side toward the glass door 15 as in the first embodiment, and accordingly, the press attachment 1 also moves in the same direction, and as shown in FIG. The head 3 comes into contact with the glass door 15 via the contact surface plate 7.

  As shown in FIG. 15, after the head 3 of the pressing attachment 1 contacts the glass door 15 via the contact surface plate 7, the rotating attachment 2 is further rotated to move the rotating attachment 2 by a predetermined distance. The distal end surface 5 a of the distal end portion 5 of the pressing attachment 1 comes into contact with the inner peripheral bottom surface 10 a of the second space portion 10 of the rotary attachment 2.

  As described above, when the distal end surface 5a of the distal end portion 5 of the pressing attachment 1 is in contact with the inner peripheral bottom surface 10a of the second space portion 10 of the rotating attachment 2, the rotating attachment 2 is finally rotated and tightened. The head 3 of the attachment 1 presses the glass door 15 via the contact surface plate 7, whereby the glass door 15 is fixed in the frame body 12. This is the same as in the first embodiment.

The rotary attachment 2 is rotated by the male screw 11 on the outer peripheral surface thereof being screwed into the female screw 14 on the inner peripheral surface of the hole 13 of the frame body 12, but it is pressed against the female screw 9 on the inner peripheral surface of the rotary attachment 2. Since the external thread 6 on the outer peripheral surface of the attachment 1 is not screwed together, the front end surface 5a of the pressing attachment 1 is in contact with the inner peripheral bottom surface 10a of the rotary attachment 2 as in the first embodiment. When the rotary attachment 2 is rotated, the rotational force of the attachment 2 is converted to a pressing force in the straight direction in which the pressing attachment 1 presses the glass door 15 without rotating. Accordingly, since the pressing attachment 1 presses the glass door 15 via the contact surface plate 7 with the pressing force in the straight traveling direction, a force such as twisting does not act on the intervening contact surface plate 7. The contact surface plate 7 is not inadvertently detached from the head 3 of the pressing attachment 1.
Also in this embodiment, since the tip surface 5a of the pressing attachment 1 and the inner peripheral bottom surface 10a of the rotating attachment 2 are in a point contact state, the rotating force of the rotating attachment 2 is pressed as in the first embodiment. It will be efficiently converted into a pressing force in the straight direction of the attachment 1.
Furthermore, also in this embodiment, the pressure attachment 1 and the rotation attachment 2 are made of a material having a smooth surface such as metal, and the contact surface plate 7 is elastic and has a high frictional resistance rubber. The frictional resistance between the contact surface plate 7 and the glass door 15 and the frictional resistance between the front end surface 5a of the pressing attachment 1 and the inner peripheral bottom surface 10a of the rotary attachment 2 are configured. Due to the difference in height, even if the rotary attachment 2 rotates, the pressing attachment 1 does not rotate, and the rotational force of the rotating attachment 2 converts the pressure attachment 1 into a pressing force in the straight direction. It will occur smoothly.

(Embodiment 3)
In the present embodiment, the one end face 18 of the rotary attachment 2 in which the opening 19 is formed contacts and presses the back surface side of the head 3 of the press attachment 1, whereby the head 3 of the press attachment 1. The front side is configured to be in pressure contact with the glass door 15. In this respect, the inner peripheral bottom surface 10a of the second space portion 10 of the rotary attachment 2 contacts and presses the distal end surface 5a of the distal end portion 5 of the pressing attachment 1, whereby the head 3 of the pressing attachment 1 is moved to the glass door. 15 is different from that of the first embodiment, which is configured so as to be able to press contact with 15.

  However, the basic configuration of the push screw tool composed of the pressing attachment 1 and the rotating attachment 2 is common to the first embodiment. That is, also in the present embodiment, as shown in FIG. 16, the pressing attachment 1 is composed of a head portion 3, a trunk portion 4, and a tip portion 5, a male screw 6 is formed on the outer peripheral surface of the tip portion 5, A contact surface plate 7 is adhered to the surface of the head 3 on the opposite side to the continuous surface.

  Further, the rotary attachment 2 is formed with a first space portion 8 having a female screw 9 and a second space portion 10 communicating with the first space portion 8, and a male screw 11 is formed on the outer peripheral surface.

  Also in the present embodiment, as in the first embodiment, the pressing attachment 1 is used by using the frame body 12 having a substantially U-shaped cross section in which the hole 13 is formed on the other piece 12b side as shown in FIGS. The female screw 9 on the inner peripheral surface of the rotary attachment 2 is screwed into the male screw 6 at the distal end portion 5 of the pressing attachment 1 by being inserted into the hole 13 of the frame body 12, and the male screw 11 on the outer peripheral surface of the rotary attachment 2 and the frame member 12. The internal thread 14 of the inner peripheral surface of the hole 13 is screwed together, and the end of the glass door 15 is inserted into the frame 12 as shown in FIG.

  The edge part of the glass door 15 is made to contact the piece 12a of the frame 12 indirectly via the contact surface plate 16 like the figure. At this time, a gap 17 is generated between the surface opposite to the end of the glass door 15 and the contact surface plate 7 of the pressing attachment 1 as in the first embodiment.

  When the rotation attachment 2 is rotated in the tightening direction in this state, the rotation attachment 2 moves to the side toward the glass door 15, and accordingly, the pressing attachment 1 also moves in the same direction, and the head 3 of the pressing attachment 1. Will come into contact with the glass door 15 via the contact surface plate 7.

  After the head 3 of the pressing attachment 1 contacts the glass door 15 via the contact surface plate 7, the rotating attachment 2 is further rotated, and when the rotating attachment 2 moves a predetermined distance, the male screw 6 of the pressing attachment 1 and the rotating attachment are rotated. As shown in FIG. 18, the distal end portion 5 of the pressing attachment 1 enters the second space portion 10 of the rotary attachment 2 and is accommodated in the second space portion 10. The Rukoto.

  In the present embodiment, as shown in FIG. 18, before the tip surface 5 a of the tip portion 5 of the pressure attachment 1 comes into contact with the inner peripheral bottom surface 10 a of the second space portion 10 of the rotation attachment 2, the opening portion of the rotation attachment 2 is opened. The end face 18 contacts the head 3 of the pressure attachment 1, thereby prohibiting further movement of the rotary attachment 2.

  Therefore, in the present embodiment, the inner peripheral bottom surface 10a of the second space portion 10 of the rotary attachment 2 does not press the front end surface 5a of the front end portion 5 of the pressing attachment 1 as in the first and second embodiments. When the end face 18 of the opening of the attachment 2 presses the head 3 of the pressing attachment 1, the head 3 of the pressing attachment 1 presses the glass door 15.

  In this respect, the present embodiment is different from the first and second embodiments. However, as described above, when the rotary attachment 2 moves by a predetermined distance, the male screw 6 of the pressing attachment 1 and the female screw 9 of the rotary attachment 2 are used. The distal end portion 5 of the pressing attachment 1 is stored in the second space portion 10 of the rotating attachment 2, and the rotational force of the rotating attachment 2 advances straightly pressing the glass door 15 of the pressing attachment 1. The action of being converted into a directional pressing force is the same as in the first embodiment.

That is, when the rotary attachment 2 is finally rotated and tightened, the rotary attachment 2 rotates because the external thread 11 on the outer peripheral surface thereof is engaged with the internal thread 14 on the inner peripheral surface of the hole 13 of the frame body 12. However, since the female screw 9 on the inner peripheral surface of the rotary attachment 2 and the male screw 6 on the outer peripheral surface of the press attachment 1 are not screwed together, the press attachment 1 does not rotate, and the end surface of the opening of the rotary attachment 2 When the rotary attachment 2 is rotated while 18 is in contact with the head 3 of the pressing attachment 1, the rotational force of the rotating attachment 2 is a push in the straight direction that presses the glass door 15 without rotating the pressing attachment 1. It will be converted to pressure.
In this case, since the pressing attachment 1 and the rotating attachment 2 are made of a material having a smooth surface such as metal or hard synthetic resin as described above, the back side of the head 3 of the pressing attachment 1 In the state where one end face 18 of the rotary attachment 2 is in contact, the frictional resistance is small on both contact surfaces, while the contact surface plate 7 is made of a material such as rubber having elasticity and high frictional resistance. Therefore, the rotation attachment 2 rotates due to the difference in the frictional resistance between the contact surface plate 7 and the glass door 15 and the frictional resistance between the pressure attachment 1 and the rotation attachment 2. Even so, the pressing attachment 1 does not rotate, and the rotational force of the attachment 2 can be reduced as in the first and second embodiments. What action the pressing attachment 1 is converted into the pressing force of the rectilinear direction of pressing the glass door 15 is to occur smoothly.
However, in the present embodiment, the back surface side of the head 3 of the pressing attachment 1 and the one end surface 18 of the rotating attachment 2 are in contact with each other in a surface contact state, so that the pressing attachment 1 and the rotating attachment 2 are in a point contact state. Compared with the case of the said Embodiment 1 and 2 which contact | abuts, the frictional resistance is somewhat large, and in the point which produces the effect | action which converts the rotational force of the attachment 2 into the pressing force of the linear movement direction of the pressure attachment 1, said Embodiment 1 2 is better.
In this case, by forming one end face 18 of the rotary attachment 2 in a curved shape, the contact area between the back surface side of the head 3 of the pressing attachment 1 and the one end face 18 of the rotary attachment 2 is reduced. It is possible to improve the action of converting the rotational force into the pressing force in the straight direction of the pressing attachment 1.

  Also in the present embodiment, the pressing attachment 1 presses the glass door 15 via the contact surface plate 7 with a pressing force in the straight direction, so that a force such as twisting acts on the intervening contact surface plate 7. Nonetheless, the contact surface plate 7 is not inadvertently detached from the head 3 of the pressure attachment 1.

(Embodiment 4)
In the present embodiment, as shown in FIG. 19, the opening 19 is not only formed on the one end surface 18 side of the rotary attachment 2 on the side screwed with the pressing attachment 1, but also on the other end surface 20 side. The opening 21 is formed, and in this respect, the opening 19 is formed only on the one end face 18 side, and the opening is not formed on the other end face side, and is formed in a closed state. This is different from Embodiments 1 to 3.

  As shown in FIG. 20, a groove 22 is formed on the other end surface 20. The groove portion 22 is for engaging a separate attachment for rotating the rotary attachment 2 so that the operation can be easily performed when the rotary attachment 2 is rotated.

  The configuration other than that the opening 21 is formed on the other end face 20 side of the rotary attachment 2 is the same as in the first to third embodiments. That is, also in the present embodiment, as shown in FIG. 19, the pressing attachment 1 includes a head portion 3, a body portion 4, and a tip portion 5, and a male screw 6 is formed on the outer peripheral surface of the tip portion 5, A contact surface plate 7 is adhered to the surface of the head 3 on the opposite side to the continuous surface.

  Further, the rotary attachment 2 is formed with a first space portion 8 having a female screw 9 and a second space portion 10 communicating with the first space portion 8, and a male screw 11 is formed on the entire outer peripheral surface. Yes. In the present embodiment, since the opening 21 is formed not only on the one end face 18 side of the rotary attachment 2 but also on the other end face 20 side as described above, the second embodiment as in the first to third embodiments. The space portion 10 does not become concave, and therefore, there is an advantage that the size of the male screw 11 formed on the entire outer peripheral surface of the rotary attachment 2 can be shortened as compared with the first to third embodiments.

  Also in this embodiment, as shown in FIG. 21, the press attachment 1 is inserted into the hole 13 of the frame body 12 using the frame body 12 having a substantially U-shaped cross-section in which the hole 13 is formed on the other piece 12 b side. At the same time, the female screw 9 on the inner peripheral surface of the rotary attachment 2 is screwed into the male screw 6 on the distal end portion 5 of the pressing attachment 1, and the male screw 11 on the outer peripheral surface of the rotary attachment 2 and the inner peripheral surface of the hole 13 in the frame body 12. The female screw 14 is screwed. Then, as shown in FIG. 21, the end of the glass door 15 is inserted between the head 3 (more specifically, the contact surface plate 7) of the pressure attachment 1 and the piece 12 a of the frame 12.

  Also in this embodiment, when the rotation attachment 2 is rotated in the tightening direction, the rotation attachment 2 moves to the side toward the glass door 15, and accordingly, the pressing attachment 1 also moves in the same direction, and the head of the pressing attachment 1. The part 3 comes into contact with the glass door 15 via the contact surface plate 7.

  After the head 3 of the pressing attachment 1 contacts the glass door 15 via the contact surface plate 7, the rotating attachment 2 is further rotated, and when the rotating attachment 2 moves by a predetermined distance, the pressing attachment 1 as shown in FIG. The screwed state of the male screw 6 and the female screw 9 of the rotary attachment 2 is released, and the distal end portion 5 of the pressing attachment 1 enters the second space portion 10 of the rotary attachment 2 and is stored in the second space portion 10. The Rukoto. This is the same as in the first to third embodiments.

  In the present embodiment, as described above, since the opening 21 is formed not only on the one end face 18 side of the rotary attachment 2 but also on the other end face 20 side, the pressure attachment is provided as in the first and second embodiments. The front end surface 5 a of the first front end portion 5 does not come into contact with the inner peripheral bottom surface 10 a of the second space portion 10 of the rotary attachment 2. That is, as in the third embodiment, the end face 18 of the opening of the rotary attachment 2 comes into contact with the head 3 of the pressing attachment 1, thereby prohibiting further movement of the rotary attachment 2.

  Accordingly, also in the present embodiment, as in the third embodiment, the end face 18 of the opening of the rotary attachment 2 presses the head 3 of the pressing attachment 1, so that the head 3 of the pressing attachment 1 is the glass door 15. Will be pressed.

Then, when the rotary attachment 2 moves by a predetermined distance, the screwed state of the male screw 6 of the pressing attachment 1 and the female screw 9 of the rotating attachment 2 is released, and the distal end portion 5 of the pressing attachment 1 is the second space portion of the rotating attachment 2. 10, the rotational force of the rotary attachment 2 is converted into a pressing force in the straight direction that presses the glass door 15 of the pressing attachment 1, and the same action as in Embodiments 1 to 3 occurs.
In this case, since the pressing attachment 1 and the rotating attachment 2 are made of a material having a smooth surface such as metal or hard synthetic resin as described above, the pressing attachment 1 of the pressing attachment 1 is the same as in the third embodiment. In a state where the back surface side of the head 3 and one end face 18 of the rotary attachment 2 are in contact with each other, the frictional resistance is small at the contact surface between them, while the contact surface plate 7 has a frictional resistance having elasticity. Since it is made of a material such as a large rubber, the difference between the frictional resistance between the contact surface plate 7 and the glass door 15 and the frictional resistance between the pressing attachment 1 and the rotating attachment 2 is different. Thus, even if the rotary attachment 2 rotates, the press attachment 1 does not rotate, and the rotary attachment mem- ber as in the first embodiment. By the rotational force of the bets 2, effect of pressing the attachment 1 is converted into the pressing force of the rectilinear direction of pressing the glass door 15 is to occur smoothly.
However, in the present embodiment, the back surface side of the head 3 of the pressing attachment 1 and the one end surface 18 of the rotating attachment 2 are in contact with each other in a surface contact state, so that the pressing attachment 1 and the rotating attachment 2 are in a point contact state. Compared with the case of the said Embodiment 1 and 2 which contact | abuts, the frictional resistance is a little large, and the said embodiment produces the effect | action which converts the rotational force of the attachment 2 into the pressing force of the straight direction of the attachment 1 1 and 2 are better.

  Also in the present embodiment, the pressing attachment 1 presses the glass door 15 via the contact surface plate 7 with a pressing force in the straight direction, so that a force such as twisting acts on the intervening contact surface plate 7. Nonetheless, the contact surface plate 7 is not inadvertently detached from the head 3 of the pressure attachment 1.

(Embodiment 5)
In the present embodiment, the male screw 6 is not formed on the outer peripheral surface of the pressing attachment 1, and this is different from the first to fourth embodiments in which the male screw 6 is formed.

  The pressing attachment 1 is common to the first embodiment in that the pressing attachment 1 includes a substantially disc-shaped head portion 3 that functions as a pressing portion that presses the attached body and a substantially cylindrical body portion 4. However, in this embodiment, the distal end portion 5 on the distal end side of the body portion 4 is formed in a concave shape as shown in FIG. 23, and the distal end surface 5a of the distal end portion 5 protrudes outward in this respect. This is different from the first embodiment which is formed in such a curved shape.

  Further, of both surfaces of the head 3 of the pressure attachment 1, the surface opposite to the surface on which the body 4 is connected is made of rubber or a synthetic resin having elasticity as shown in FIG. The contact surface plate 7 is adhered, and this point is also common to the first embodiment.

  The rotary attachment 2 has not only an opening 19 on one end face 18 side, but also an opening 21 on the other end face 20 side. To do. The relatively shallow first space 8 is formed in communication with the opening 19 and the second space 10 is formed in common with the first to fourth embodiments. However, in the present embodiment, since the male screw 6 is not formed on the outer peripheral surface of the pressing attachment 1 as described above, the female screw 9 is not formed on the inner peripheral surface of the first space portion 8 of the rotary attachment 2. This is different from the first to fourth embodiments. The point that the male screw 11 is formed on the outer peripheral surface of the rotary attachment 2 is the same as in the first to fourth embodiments.

  In the present embodiment, as shown in FIG. 24, the distal end portion 5 and the body portion 4 of the pressing attachment 1 are inserted into the first space portion 8 from the opening portion 19 of the rotary attachment 2, and further, as shown in FIG. The pressing attachment 1 is inserted into the first space portion 8 and the second space portion 10 of the rotating attachment 2 so that the tip portion 5 of the pressing attachment 1 protrudes into the second space portion 10 of the rotating attachment 2.

  With the pressing attachment 1 being inserted into the first space 8 and the second space 10 of the rotary attachment 2 in this way, the tip 5 of the pressing attachment 1 is hit with a hitting tool or the like as shown in FIG. It shall be in a state where it is caulked. As a result, both side portions 5 b and 5 c of the distal end portion 5 of the pressure attachment 1 are in close contact with the end surface of the second space portion 10 adjacent to the first space portion 8. As a result, the pressing attachment 1 and the rotating attachment 2 are integrated, and the rotating attachment 2 is prevented from being detached from the pressing attachment 1. When performing such a caulking operation, a slight gap for so-called play is formed between the end face 18 of the opening 19 of the rotary attachment 2 and the head 3 of the pressing attachment 1 as shown in FIG. Preferably, for example, an ultra-thin intervening material is interposed between the end face 18 of the opening of the rotary attachment 2 and the head 3 of the pressing attachment 1, and the intercalating material is removed after the caulking operation. The gap can be formed by, for example.

  The pressing attachment 1 and the rotating attachment 2 are combined as described above, and the pressing attachment 1 and the rotating attachment 2 are combined into the hole 13 of the frame 12 as shown in FIG. . Further, as shown in the figure, the end portion of the glass door 15 is inserted between the head 3 of the pressing attachment 1 (more specifically, the contact surface plate 7) and the piece 12a of the frame body 12.

  In the present embodiment, since the male screw 6 is not formed on the pressing attachment 1 and the female screw 9 is not formed on the rotating attachment 2, the pressing attachment 1 and the rotating attachment 2 are not screwed together. A male screw 11 is formed on the outer peripheral surface of the rotary attachment 2. Since the female screw 14 screwed with the male screw 11 is formed on the inner peripheral surface of the hole 13 of the frame body 12, the rotary attachment 2 and the hole 13 of the frame body 12 are screwed together.

  When the rotary attachment 2 is rotated in the tightening direction in the screwed state, the rotary attachment 2 moves to the side toward the glass door 15 as in the first to fourth embodiments. However, since the rotary attachment 2 and the press attachment 1 are not screwed together, the press attachment 1 does not move as the rotary attachment 2 moves.

  When the rotary attachment 2 moves by a predetermined distance, the end face 18 of the opening of the rotary attachment 2 comes into contact with the head 3 of the pressing attachment 1, and when the rotary attachment 2 is further rotated and moved toward the glass door 15, Accordingly, the pressing attachment 1 also moves.

  Then, when the pressing attachment 1 moves by a predetermined distance and the head 3 of the pressing attachment 1 comes into contact with the glass door 15 via the contact surface plate 7 as shown in FIG. 27, the pressing attachment 1 moves further. Will be prohibited.

The rotary attachment 2 has room to move, and the head 3 of the pressing attachment 1 has not yet reached the state in which the glass door 15 is pressed.

  Finally, as shown in FIG. 28, the rotary attachment 2 is rotated and tightened, so that the head 3 of the press attachment 1 presses the glass door 15. At this time, due to the slight gap as described above, the rotary attachment 2 slightly moves in the direction of the glass door 15, and the end face 18 of the opening 19 of the rotary attachment 2 and the head 3 of the press attachment 1 are connected. In this way, the head 3 of the pressure attachment 1 is suitably brought into pressure contact with the glass door 15 via the contact surface plate 7.

In this embodiment, since the pressing attachment 1 and the rotating attachment 2 are not screwed together, the rotating attachment 2 initially moves while rotating, but the pressing attachment 1 moves without rotating from the beginning. However, the head 3 of the pressure attachment 1 presses the glass door 15 through the contact surface plate 7, and at that time, the rotational force of the rotation attachment 2 pushes the glass door 15 of the pressure attachment 1 in the straight direction. It is common to the first to fourth embodiments in that the pressing force acts.
In this case, since the pressing attachment 1 and the rotating attachment 2 are made of a material having a smooth surface such as metal or hard synthetic resin, the head of the pressing attachment 1 is the same as in the third and fourth embodiments. In the state where the back surface side of 3 and one end face 18 of the rotary attachment 2 are in contact with each other, the frictional resistance is small at the contact surface between them, while the contact surface plate 7 is elastic and has a high frictional resistance rubber. The frictional resistance between the contact surface plate 7 and the glass door 15 and the frictional resistance between the pressing attachment 1 and the rotating attachment 2 are different from each other. Even if the rotation attachment 2 rotates, the pressure attachment 1 does not rotate, and the pressure attachment is performed by the rotational force of the attachment 2. Action cement 1 is converted into the pressing force of the rectilinear direction of pressing the glass door 15 is to occur smoothly.

  Also in this embodiment, the pressing force in the straight direction of the pressing attachment 1 acts, and the operation of fixing and attaching the glass door 15 can be suitably performed. Further, since the pressing attachment 1 presses the glass door 15 via the contact surface plate 7 with the pressing force in the straight traveling direction, a force such as twisting does not act on the intervening contact surface plate 7, The contact surface plate 7 is not inadvertently detached from the head 3 of the pressing attachment 1.
