First Embodiment
The first embodiment of the present invention will be described in detail below with reference to FIG.
The rotary operation member 1 in the present embodiment includes a handle portion 11 corresponding to a door knob, a knob of furniture, a knob of a volume of an audio device, or the like, and a rotary shaft portion which rotates the handle portion 11 to rotate around an axis. And a bearing 20 for supporting the rotating shaft portion 12. The handle portion 11 is a portion that a user grips with a hand or pinches with a fingertip when rotating the rotation shaft portion 12. The handle portion 11 has a block shape, and the rotation shaft portion 12 has a cylindrical shape. The rotating shaft 12 projects in one direction from the center of the handle 11. The rotating shaft portion 12 and the handle portion 11 are integrally provided.

The bearing 20 includes a case 21 for holding the rotary shaft 12 and a plurality of granular bodies 23 in contact with the outer surface of the rotary shaft 12.
The case 21 has a box shape that can accommodate a part of the rotary shaft 12 and the particulates 23 therein, and holds the rotary shaft 12 in a rotatable state. The case 21 is fixed to various articles (furniture, doors, audio equipment, etc.).

The case 21 includes a cylindrical first wall 24 surrounding the rotation shaft 12 and a pair of second walls 25 closing the openings at both ends in the axial direction of the first wall 24. The first wall portion 24 has a cylindrical shape that is slightly larger than the rotation shaft portion 12. An inner surface of the first wall portion 24 (hereinafter, referred to as a first wall surface 26) faces the outer surface of the rotation shaft portion 12 in parallel. The inner surfaces of the pair of second wall portions 25 (hereinafter referred to as second wall surfaces 27) are perpendicular to the axis of the rotary shaft portion 12.

The case 21 is formed with a through hole 28 through which the rotary shaft 12 passes. The through hole 28 has a size such that the rotary shaft portion 12 can rotate freely, and is sized such that the granular material 23 does not leak from the space between the through hole 28 and the rotary shaft portion 12. The through holes 28 are coaxially formed through the pair of second wall portions 25.

A storage space S in which the granular material 23 is stored is provided inside the case 21 (between the rotary shaft portion 12). The storage space S is provided over the entire circumference of the rotary shaft portion 12. The storage space S is a space surrounded by the inner surface (the first wall surface 26 and the pair of second wall surfaces 27) of the case 21 and the outer surface of the rotary shaft portion 12.

Of the pair of second wall portions 25, one second wall portion 25 (the second wall portion 25 located on the opposite side to the handle portion 11) is used as a change member 29 for changing the size of the storage space S There is. The change member 29 is movable along the axial direction of the rotation shaft 12.

The change member 29 is attached to an opening 32 provided in the case 21. The opening 32 is an opening at one end side of the first wall 24 in the axial direction, and the first wall 24 and the other second wall 25 (the second wall 25 located on the handle 11 side) The internal space of the case main body 31 is opened to the outside. The granular material 23 is accommodated in the internal space of the case main body 31 from the opening 32. The opening 32 is provided on the entire surface on one end side of the first wall 24.

The change member 29 is attached to the opening 32 so as to be movable along the axial direction of the rotation shaft 12. The change member 29 is detachably attached to the case main body 31. When the change member 29 is attached to the case main body 31, the opening 32 is closed by the change member 29, and the change member 29 is the case main body 31. In the state where it is removed from the whole, the opening 32 is opened.

The change member 29 includes an insertion portion 33 inserted inside the case main body 31 and a hook portion 34 disposed outside the case main body 31. The insertion portion 33 has an axial shape that can be fitted into the opening 32. The distal end surface of the insertion portion 33 inserted into the opening 32 faces the storage space S and constitutes a second wall surface 27. The collar portion 34 is provided at one end in the axial direction of the insertion portion 33 and protrudes around the entire circumference. The collar portion 34 functions as a stopper portion that abuts on the outer surface of the case main body 31 to prevent excessive insertion of the change member 29 into the storage space S.

The through hole 28 provided in the change member 29 has the same size as the through hole 28 of the opposing second wall 25 (the size of the rotatable shaft 12 is rotatable, and the granular material 23 from the through hole 28 is It is considered as a size that does not leak out. The through hole 28 is formed at the center of the insertion portion 33.

The change member 29 and the case main body 31 are provided with a fixing structure 35 which can appropriately move the change member 29 in both the inner and outer directions of the case 21 and can fix the change member 29 at a predetermined position. The fixing structure 35 is a screwing structure, and includes a male screw portion provided on one of the change member 29 and the case main body 31, and a female screw portion provided on the other. The male screw portion is provided in the insertion portion 33 of the change member 29, and the female screw portion is provided in the opening 32 of the case main body 31. Since the screwing structure is provided, the insertion amount (protrusion amount) of the insertion portion 33 into the storage space S can be appropriately changed by rotating the change member 29.

In the storage space S, a large number of granular bodies 23 are stored. The particulates 23 are small particles (for example, about 2 mm in particle diameter), and are uniformly filled in the entire storage space S. The particulates 23 are solid in a spherical shape, and all have the same shape. The diameter dimensions (sizes) of all the granular bodies 23 are the same. The granular body 23 is an elastic body, for example, an elastomer (elastomer) particle. The granular body 23 is in close contact with the inner surface of the case 21 (the first wall surface 26 and the pair of second wall surfaces 27) and the outer surface of the rotary shaft portion 12.

Next, a usage example in which the rotation operation member 1 of the present embodiment is used in a door latch device will be described.
When the door knob as the handle portion 11 is rotated in one direction when the door is opened, the rotation shaft portion 12 is rotated. At this time, although the particulates 23 in contact with the outer surface of the rotating shaft 12 try to rotationally move together with the rotating shaft 12, the particulates 23 filled in the storage space S are between the adjacent particulates 23. The free rotational movement is restrained by the frictional force. For this reason, when the rotating shaft 12 rotates, a frictional force is generated between the rotating shaft 12 and the granular material 23. The friction force acts on the rotation shaft 12 in a direction to suppress the rotation of the rotation shaft 12, so the doorknob becomes heavy.

Here, when the turning comfort of the doorknob is too light, the user may feel cheapness, but according to the rotation operation member 1 of the present embodiment, a proper weight is given to the turning comfort, Can create a sense of luxury. Thus, the rotation shaft portion 12 rotates, and the latch bolt retracts from the door frame while elastically deforming the biasing member (not shown), and the door can be opened.

When the hand is released from the handle portion 11 rotated in one direction, the latch bolt tries to return to the original position by the biasing force of the biasing member, and the rotary shaft portion 12 rotates back in the other direction accordingly. At this time, as described above, when the rotary shaft 12 returns and rotates, a frictional force is generated between the rotary shaft 12 and the granular material 23, and this frictional force is in the direction to suppress the return rotation of the rotary shaft 12. Since the force acts on the rotary shaft 12, the rotary shaft 12 is slowly returned and rotated.

Here, in the case where the rotating shaft portion 12 is vigorously returned and rotated by the biasing force of the biasing member, noise may occur when the handle portion 11 returns to the original state. However, in the present embodiment, since the rotary shaft portion 12 is slowly returned and rotated, the generation of such a sound can be suppressed, and a high-class feeling can be created.

Furthermore, the rotational operation member 1 of the present embodiment can adjust the rotational comfort of the handle portion 11 by increasing or decreasing the frictional force by the granular material 23. Specifically, for example, the size, the size, the shape, and the like of the granular body 23 can be changed to change the magnitude of the frictional force by the granular body 23. Further, the amount of pressing of the change member 29 can be changed to change the magnitude of the frictional force by the granular material 23. That is, the pushing amount of the change member 29 into the storage space S is increased, the storage space S is narrowed, the elastic deformation of the granular body 23 is increased (elastic force of the granular body 23 is increased), and the frictional force by the granular body 23 is increased. be able to. Further, the amount of pushing of the change member 29 into the storage space S can be reduced to widen the storage space S, and the frictional force by the granular material 23 can be reduced.

Next, the operation and effects of the embodiment configured as described above will be described.
The rotation operation member 1 according to the present embodiment includes an operation unit main body 10, a case 21, and a plurality of granular bodies 23, and the operation unit main body 10 operates the handle portion 11 and the handle portion 11 to rotate around an axis. The case 21 has a storage space S between itself and the rotary shaft 12 to hold the operation unit main body 10 in a rotatable state of the rotary shaft 12, The granular material 23 is stored in the storage space S and is in contact with the outer surface of the rotating shaft portion 12.

According to this configuration, when the rotary shaft 12 rotates, a frictional force is generated between the rotary shaft 12 and the granular material 23, and the frictional force is a force in the direction to suppress the rotation of the rotary shaft 12. Since it acts on the rotation shaft portion 12, the operability (turning comfort) of the handle portion 11 can be adjusted by adjusting the magnitude of the frictional force by the granular material 23. Therefore, a good result can be obtained by sensory evaluation.

In addition, the rotation operation member 1 is provided with a change member 29 that changes the size of the storage space S. According to this configuration, since the size of the storage space S can be changed to change the frictional force by the granular material 23, the operability of the handle portion 11 can be easily adjusted.
