  However, in the conventional attaching and detaching device disclosed in Patent Document 1, the hinge rod attached to the toilet seat joint rotates around the projection of the fixing adapter. Further, in the conventional attaching and detaching device disclosed in Patent Document 2, the casing attached to the toilet seat rotates around the hinge pin. For this reason, in each conventional detachable device, the toilet seat and the toilet seat cover rotate with respect to the toilet bowl, and along with this, the toilet seat and the toilet seat cover become oblique or rattled, and set in a predetermined position I could not do that.

The present invention has been made to solve such problems.
One object is attached to the other object by engaging between the one object and the other object, and one object is separated from the other object by disengaging the one and the other object, In the detaching device for detachably attaching one object to the other,
A hinge pin, one end of which is attached to the side of the other object;
An elastic member wound around the other end of the hinge pin;
A housing portion formed to open in a direction orthogonal to the axial direction, which accommodates an elastic member wound on the other end side of the hinge pin and rotatably fitted on the other end side of the hinge pin; And a lock groove formed on the side end face for exposing at least one end portion from the side end face of the housing portion and moving the end portion in a direction in which the elastic member is wound around the other end side of the hinge pin. An adapter attached to the side of one of the objects;
The covering portion covering the outer periphery of the adapter in which the housing portion is fitted to the other end side of the hinge pin, the covering portion of the covering portion intersecting the hinge pin is cut when the covering portion is rotated around the adapter axis along the outer periphery of the adapter An elastic member is engaged with the end portion exposed from the lock groove when the covering portion is formed so as to protrude on the covering inner surface of the covering portion facing the side end face and the elongated hole formed by being notched. A cover having a projection which is wound around the other end of the hinge pin to lock the rotation of the adapter, the axis being concentric with the axis of the adapter,
And a holding mechanism for holding the projection against the elastic force of the elastic member at a winding position where the elastic member is wound around the other end of the hinge pin.

  According to this configuration, one end of the hinge pin is attached to the other object side, the adapter is attached to the one object side, the housing portion of the adapter is fitted into the other end side of the hinge pin, and the other end side of the hinge pin is resilient in the housing portion. By winding the members, one object can be attached to the other. In this state, by rotating the cover of the cover along the outer periphery of the adapter around the axis of the adapter, a projection formed on the inner surface of the cover of the cover is formed on the side end face of the adapter. Engage with the end of the elastic member exposed from the lock groove to push the end in the circumferential direction. The elastic member is wound around the other end of the hinge pin by this pressing force. This state in which the projection is in the winding position is held by the holding mechanism against the elastic force of the elastic member. When the elastic member is held in a state of being wound around the other end of the hinge pin, the elastic member accommodated in the housing of the adapter is tangled with the other end of the hinge pin, and rotation of the adapter with respect to the hinge pin is blocked and locked. . Thus, one of the objects attached to the adapter does not pivot as conventionally with respect to the other object attached to the hinge pin. As a result, one object can be easily attached to and removed from the other object, and one object can be put in place without oblique or rattling with respect to the other object. It becomes possible to set.

  Further, according to the present invention, the holding mechanism is formed so as to be recessed on the outer periphery of the adapter on the locus drawn by the engaging portion formed by projecting on the inner periphery of the covering and the covering portion being rotated. The first engaging portion and the first engaging portion are engaged with each other when the projecting portion is in the winding position, and the projecting portion is held in the winding position. I assume.

  According to this configuration, the cover portion of the cover rotates around the axis of the adapter along the outer periphery of the adapter, and the engagement portion formed on the inner periphery of the cover portion and the first cover formed on the outer periphery of the adapter The protrusion is held at the winding position by engagement with the engagement portion. Therefore, the elastic member is held in the state of being wound around the other end side of the hinge pin by the projection, and the rotation lock state of the adapter is maintained.

  In the present invention, the holding mechanism has a second engaged portion formed on the outer periphery of the adapter on the locus drawn by the covering portion while the covering portion rotates, and the elastic member is a hinge pin other than the hinged pin. It is characterized in that the engaging portion and the second engaged portion are engaged to hold the protrusion in the relaxed position when the protrusion is present in the relaxed position where the end is not wound.

  According to this configuration, the cover of the cover rotates around the axis of the adapter along the outer periphery of the adapter, and the second cover formed on the outer periphery of the engaging portion formed on the inner periphery of the cover and the adapter The projection is held in the relaxed position by engagement with the engagement portion. Therefore, the elastic member is held by the projecting portion so as not to be wound on the other end side of the hinge pin, and the entanglement of the elastic member with respect to the hinge pin is released. Therefore, by moving the adapter in the axial direction of the hinge pin, the other end side of the hinge pin can be removed from the housing of the adapter, and the adapter can be disengaged from the hinge pin. Further, the covering portion is rotated around the axis of the adapter along the outer periphery of the adapter, and the first engaged portion and the second engaging portion formed on the inner periphery of the covering portion are formed on the outer periphery of the adapter The movement of the adapter relative to the hinge pin can be easily locked and unlocked by moving between the engaged portions.

In the present invention, the holding mechanism is
A projection formed on an inner periphery of the covering portion which is axially separated from the covering inner surface of the covering portion facing the side end face by a predetermined length;
At a circumferential position where the protrusion is present at a relaxed position where the elastic member is not wound on the other end of the hinge pin, the outer periphery of the adapter is axially aligned along a predetermined length from one end surface of the adapter A slide groove for guiding a projection, which is formed on the outer periphery of the adapter along the circumferential direction of the adapter and then along the axial direction until the
It is characterized by being composed of

  According to this configuration, the circumferential position about the axial center of the projection formed on the inner periphery of the covering portion and the slide groove formed in the axial direction and a predetermined length on the outer periphery of the adapter is aligned, and the cover is made in the axial direction By moving along the outer periphery of the adapter, the projection moves a predetermined length along a slide groove formed in a predetermined length in the axial direction, and the attachment of the cover to the adapter is guided. Subsequently, by rotating the cover covering the adapter around the axis along the outer periphery of the adapter, the protrusion moves along the slide groove formed in the circumferential direction. The cover rotates in the circumferential direction and continues until the projection reaches the axially formed slide groove, and the projection is guided to the winding position. When the projection is at the winding position, the end of the elastic member is pushed by the projection and the elastic member is wound around the other end of the hinge pin. In this state, the elastic member housed in the housing portion entangles on the other end side of the hinge pin. Subsequently, by moving the cover in the axial direction along the outer periphery of the adapter, the projection is formed along the slide groove formed in the axial direction following the circumferential direction in a state where the protrusion is located at the winding position. Moves, and the relative position of the cover to the adapter shifts in the axial direction. By this displacement, the protrusion continues in the circumferential direction and stays in the slide groove formed in the axial direction, so that rotation of the cover in the circumferential direction is restricted, and the elastic member is entangled on the other end side of the hinge pin. It is held and the rotational lock of the adapter is maintained. This locked state can not be released unless the intended operation is performed on the cover because it can not be released without following the locus of the protrusion and moving the protrusion along the slide groove.

  Further, according to the present invention, the holding mechanism inserts the other end of the hinge pin at a circumferential position where the protrusion is present at the step formed on the outer periphery of the hinge pin and at the relaxed position where the elastic member is not wound around the other end. A first diameter portion of the elongated hole, and a second diameter portion of the elongated hole in communication with the first diameter portion engaged with the step when the covering portion is rotated about the axis and the projection is positioned at the winding position , Formed between the first diameter portion and the second diameter portion at intervals shorter than the respective diameters of the first diameter portion and the second diameter portion to resist movement of the hinge pin between the first diameter portion and the second diameter portion. It is characterized by being comprised by the narrow part of the long hole to give.

  According to this configuration, the other end side of the hinge pin is inserted into the first diameter portion of the elongated hole, and the covering portion is rotated about the axial center against the resistance by the narrow portion to place the projecting portion at the winding position When positioned, the second diameter portion of the elongated hole engages with the step formed on the outer periphery of the hinge pin. In this state, the elastic member is wound around the other end of the hinge pin by the projecting portion, and the elastic member accommodated in the accommodating portion is entwined to the other end of the hinge pin. In addition, since the narrow portion which resists the movement of the hinge pin is formed in the elongated hole between the first diameter portion and the second diameter portion, the elastic member is held in a state of being entangled on the other end side of the hinge pin Thus, the rotational lock state of the adapter is maintained. In this locked state, the cover is turned against resistance by the narrow portion to disengage the second diameter portion from the step, so the intended operation is not performed on the cover. , Can not be canceled.

  Further, in the adapter according to the present invention, the peripheral wall surrounding the periphery of the lock groove is formed so as to protrude from the side end face, and the cover protrudes in the covered inner surface raised portion of the covering portion protruding in sliding contact with the inner periphery of the peripheral wall. A part is formed.

  According to this configuration, the outer periphery of the covered inner surface raised portion of the covered portion in which the projecting portion is formed is in sliding contact with the inner circumference of the peripheral wall formed to protrude from the side end face of the adapter, whereby the covering portion rotates relative to the adapter Will be guided. Therefore, the rotational locking operation and the unlocking operation of the adapter, which is performed by rotating the covering portion, are smoothly performed with the covering inner surface raised portion guided by the peripheral wall formed on the side end surface of the adapter.

Further, according to the present invention, there is provided any one of the above attachment / detachment device having a lock mechanism
A damper case attached to the adapter or integrally formed with the adapter, and a rotating shaft accommodated in the damper case and having an axial end projecting from the damper case coupled to the one object, The hinge device is configured to include a rotary damper that resists rotation.
