Shape).
The diameter of the male member insertion hole 31b in the small diameter direction is substantially the same as the diameter of the body portion 15c of the male member 11, and the diameter of the male member insertion hole 31b in the large diameter direction prevents the male member 11 from interlocking. The protrusions 15b and 15b are formed so as to be larger than the diameter of the large diameter portion on which the protrusions 15b and 15b are formed. Thereby, when the trunk | drum 15c of the male member 11 is inserted in the male member insertion hole 31b, rotation of the male member 11 facing the male member insertion hole 31b is controlled by the interlocking prevention protrusions 15b and 15b.

  Then, in a state where the male member 11 is inserted into the male member insertion hole 31b until the head portion 15a of the male member 11 contacts the panel support plate 31, the male screw portion 12 protrudes from the male member insertion hole 31b, and the body portion 15c is inserted into the male member. It is preferable that the length of the body portion 15c of the male member 11 is substantially equal to the thickness of the panel support plate 31 so as to be accommodated in the hole 31b. The annular plate member 13 pushed into the male screw portion 12 of the male member 11 abuts on the body portion 15c of the male member 11, thereby causing the annular plate in a direction substantially orthogonal to the axial direction of the male screw portion 12. The posture of the member 13 is stabilized.

Then, the annular plate member 13 is externally fitted to the male screw portion 12 of the male member 11 in a state where the male member 11 is inserted into the male member insertion hole 31b. At this time, as shown in FIGS. 4 and 5, the panel support plate 31 is sandwiched between the head 15 a of the male member 11 and the annular plate member 13.
Since the annular plate member 13 is an elastic body, the operator can insert the male member 11 into the male member insertion hole 31b, and then push the annular plate member 13 into the male screw portion 12 for external fitting. As described above, in a state where the annular plate member 13 is attached to the male screw portion 12, the male screw portion 12 of the male member 11 protrudes from the male member insertion hole 31b.

  Thus, it is the panel fixing member 1 of the form which fastens the panel surface material 32 and the panel support plate 31, Comprising: The male member 11 which has the head 15a and the external thread part 12, and the said male member 11 is the said An annular plate member 13 fitted to the male screw portion 12 protruding to the opposite side of the head 15a of the male member 11 in a state of being inserted into either the panel face member 32 or the panel support plate 31; The female member 21 having the head 15a and the female screw portion 25c screwed with the male screw portion 12 of the male member 11 is provided, and therefore, between the annular plate member 13 and the head 15a of the male member 11. Since the panel support plate 31 can be sandwiched and the male member 11 is temporarily fixed to the panel support plate 31 in advance, the panel member 32 and the panel support plate 31 can be fastened together by the female member 21, so Panel support plate when installing handrails Hardly male member 11 is disengaged from 1, improved workability, it is possible to prevent the falling of the male member 11 or the like downstairs from blow side.

  Further, since the annular plate member 13 has an inner diameter smaller than the diameter of the thread of the male screw portion 12 of the male member 11 and larger than the diameter of the thread valley of the male screw portion 12, the annular plate member 13 is It can be fitted into the male screw portion 12 while rotating, the inner periphery of the annular plate member 13 comes into contact with the screw thread of the male screw portion 12 and is difficult to come off, and the male member 11 is temporarily fixed to the panel support plate 31. Reliability can be improved.

  Since the annular plate member 13 is made of an elastic material, the annular plate member 13 can be bent and pushed into the male screw portion 12, so that the male member 11 can be temporarily attached to the panel support plate 31 or the like. Can be stopped.

Next, as shown in FIG. 5, in the state where the male screw portion 12 of the male member 11 is inserted into the female member insertion hole 32 b formed in the panel surface material 32, the panel surface material 32 is connected to the annular plate member 13. Abut. Then, the male screw part 12 is screwed into the female screw part 25 c of the female member main body 25 while the female member 21 fitted with the washer 23 is inserted into the female member insertion hole 32 b of the panel face member 32.
At this time, since the panel support plate 31 is sandwiched between the head portion 15a of the male member 11 and the annular plate member 13, the male member 11 remains in the male member insertion hole 31b, that is, the male screw portion. 12 is held in a posture that protrudes in a substantially horizontal direction from the male member insertion hole 31b, so that the operator does not need to hold the male member 11, and can hold the panel face material 32 and operate the female member 21. You can focus on it.

  As shown in FIGS. 5 to 7, when the male screw portion 12 of the male member 11 is screwed into the female screw portion 25c of the female member 21, and the male member 11 and the female member 21 are screwed together, A panel support plate 31 is sandwiched between the head portion 15 a of the member 11 and the annular plate member 13, and a panel face member 32 is sandwiched between the annular plate member 13 and the head portion 25 a (washer 23) of the female member 21. In this state, the panel support plate 31 and the panel face member 32 are fastened together by the panel fixing member 1.

  As described above, the male member insertion hole 31b of the panel support plate 31 is formed as a long hole having a short direction and a long direction, and the interlocking prevention protrusions 15b and 15b are formed on the body portion 15c of the male member 11. Therefore, the male member 11 cannot be rotated relative to the male member insertion hole 31b. Therefore, when the male member 11 is screwed into the female member 21, the male member 11 does not rotate with the female member 21, so that the male member 11 and the female member 21 are connected by simply rotating the female member 21. Workability is improved.

  Thus, while the male member 11 of the panel fixing member 1 has the trunk | drum 15c between the head 15a of the male member 11, and the external thread part 12, the cross section by the side of the head 15a of this trunk | drum 15c is shown. The shape of the male member insertion hole 31b formed in the panel face member 32 or the panel support plate 31 is a length in the short direction, which is a substantially oval shape having a large diameter portion (15b, 15b) and a small diameter portion 15c. Is substantially the same as the diameter of the small diameter portion of the body member 15c of the male member, and is a long hole whose length in the longitudinal direction is larger than the diameter of the large diameter portion (15b, 15b) of the body portion 15c of the male member 11. Therefore, when the male member 11 is temporarily fixed to the panel support plate 31, the large-diameter portion (15 b, 15 b) of the male member 11 and the male member insertion hole 31 b of the panel support plate 31 come into contact with each other, and the male member 11 rotates. Since it is regulated, the worker can hold the female member 2 without holding the male member 11. Only for connecting the male member 11 and female member 21 by rotating, i.e. a panel surface member 32 and the panel supporting plate 31 can be fastened together.

On the other hand, the panel member 32 is provided with a female member insertion hole 32b into which the boss 25b of the female member 21 is inserted. The boss 25b of the male member 11 is formed to be rotatable with respect to the female member insertion hole 32b.
As described above, the washer 23 is an elastic body made of resin or the like, and reduces the frictional force between the head portion 25a of the female member 21 and the panel face member 32, and the head portion 25a made of metal or the like. Is configured so as not to be rubbed with the panel face material 32 and damage the surface of the panel face material 32 when rotating.

  As described above, since the washer 23 is made of an elastic material, the panel surface material 32 is sandwiched by the washer 23, so that the panel surface material 32 made of glass or the like is not damaged by the head 25a. It can be fastened together with 31 etc. Further, through the washer 23, friction is reduced as compared with the case where the head portion 25a and the panel face member 32 come into contact with each other, and the female member 21 can be easily rotated.

As described above, in this embodiment, the panel support plate 31 is described on the blow-off side, and the panel face material 32 is described on the staircase or the corridor side, and the male member 11 is inserted on the panel support plate 31 side. Although the female member 21 is inserted into the panel face member 32 side, the male member 11 and the female member 21 may be disposed in reverse, and the configuration is not limited.
That is, the structure may be such that the male member 11 is inserted into the panel face member 32 side and the female member 21 is inserted into the panel support plate 31 side. In any case, workability can be improved and the panel support can be improved. It is possible to prevent the male member 11 from dropping from the plate 31 or the panel face material 32.
