DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage-type fixing screw provided with a screw for fixing two objects, which can be stored without falling off when removed.

[0002]

2. Description of the Related Art In general, when two objects are fixed, a screw provided with a male screw is rotated and fitted into a female screw provided on one of the objects, so that one object and the other are connected with the head of the screw. And fix it.

FIG. 33 is a side view for explaining a conventional screw. That is, the screw 10 is a screw portion 1 in which a male screw is formed.
1, a neck 11 serving as a rotation axis, and a knob 13 attached to the neck 11.

FIG. 34 is a cross-sectional view for explaining a state of attachment of a conventional screw. In this example, a screw 10 is used to fix the fixed object B to the fixed base A. The screw 10 is screwed into the fixed object B via a hole of the bracket 14 attached to the fixed base A. The screw 10 is put into a bracket 14 together with a washer W for retaining the bracket, and the bracket 14 is attached to a fixed base A.

[0005] In the case of fixing, after fixing the fixing stand A on which the screw 10 is supported by the bracket 14 and the fixing object B, the screw portion 11 is screwed into the fixing object B by turning the knob 13 of the screw 10. It is fixed.

FIG. 35 is a sectional view for explaining a state where the screw 10 is removed. That is, when removing the screw 10, the knob 13 is rotated in the direction opposite to the direction at the time of attachment, and the screw 11 is removed. At this time, the screw 10 is prevented from falling off from the bracket 14 by the washer W for retaining.

[0007]

However, such a screw has the following problems. That is, the screw needs to have a total length that is the sum of the length of the screw portion, the length of the neck portion into which the washer for retaining is inserted, and the length of the knob portion, and requires a lot of space for removing the screw.

Further, as shown in the cross-sectional view of FIG. 36, when the fixing base A is disposed substantially vertically, the screw 10 becomes oblique when the screw 10 is removed, as compared with the case where the screw 10 is vertical. Requires a lot of space.

Therefore, as shown in the sectional view of FIG. 37, it is conceivable to reduce the space required when the screw 10 is removed by shortening the neck portion 12; Screws cannot be fixed.

Further, as shown in the cross-sectional view of FIG. 38, when the screw 10 is removed, the screw 10 moves within the bracket 14, and if there is vibration, a rattling sound is generated, or the knob 13 is close. The problem of hitting and scratching the object occurs.

[0011]

FIG. 3 is a sectional view for explaining a mounting state of the storage type fixing screw 1 in the first embodiment. As described above, the screw 2 is inserted into the cylindrical knob 3, and the lid 4 is attached to the opening. In this state, the flange portion F of the tubular knob portion 3 is rotatably attached to the bracket 14 attached to the fixed base A.

Next, a procedure for fixing a fixed object using the storage type fixing screw 1 rotatably attached to the fixing table A will be described. 4 and 5 are cross-sectional views for explaining the attachment.

That is, as shown in FIG. 4, when attaching the fixed base A and the fixed object B, first, the fixed base A and the fixed object B are attached.
