<Core material 20>
2A shows a perspective view of the core material 20, FIG. 2B shows a cross-sectional view of the core material 20 at IIb in FIG. 2A, and FIG. 2C shows the core material 20 in FIG. It is a side view of the core material 20 seen from IIc. In addition, the core material 20 in FIG.2 (c) is drawn so that the dimension of the up-down direction in the figure may become large compared with the dimension of the left-right direction for the sake of clarity.

First, as shown in FIG. 2A, the core member 20 as an example of the shaft member includes a first member 21 and a second member 23, each of which is a long member having a substantially hexagonal cross section. The first member 21 and the second member 23 are stacked and fixed in the vertical direction.
In the illustrated example, the first member 21 is disposed above the second member 23.
Moreover, in the example of illustration, the 1st member 21 and the 2nd member 23 are passing through the welding part 25 (refer FIG.2 (c)) to which the spot welding was performed in one edge part of the core material 20. As shown in FIG. Is fixed. More specifically, the first member 21 and the second member 23 are not fixed at the other end of the core member 20. In addition, fixation with the 1st member 21 and the 2nd member 23 may be implement | achieved by well-known techniques, such as using an adhesive material.

  Here, as shown in FIG. 2B, the upper surface 21A of the first member 21 is formed with a plurality of fixing grooves 21D over a predetermined range in the axial direction. Further, the lower surface of the side surfaces of the first member 21, that is, the first side lower surface 21 </ b> B and the second side lower surface 21 </ b> C facing the upper surface 21 </ b> A across the central axis of the first member 21 are predetermined in each axial direction.

Specifically, the first member 21 is curved so that the central portion in the axial direction protrudes upward, and the second member 23 is curved so that the central portion in the axial direction protrudes downward. More specifically, the first member 21 and the second member 23 are separated from each other at the central portion in the axial direction, and the core member 20 as a whole has a shape in which the central portion in the axial direction swells in the vertical direction. Further, the core member 20 can be elastically deformed in the vertical direction (one direction) at the central portion in the axial direction. When the core member 20 configured in this way is inserted into the case lock 50, the elastically deformable axial center portion stretches the inner peripheral surface of the cam hole (not shown) of the rotating cam via the resin cover 55. Press like so. This suppresses the inserted core member 20 from rattling in the cam hole.

<Fixed unit 40>
3A is an exploded perspective view of the fixed unit 40, FIG. 3B is a front view of the fixed plate 43, and FIG. 3C is a cross-sectional view of the fixed unit 40 in the axial direction.
As shown in FIG. 3A, the fixing unit 40 includes a substantially cylindrical holding member 41 with a part cut away, and a fixing plate supported by the holding member 41 in a direction inclined with respect to the axial direction. 43, a support pin (positioning member) 44 provided along the axial direction, a coil spring 45 supported by the support pin 44 and biasing the fixing plate 43 toward the holding member 41, and the holding member 41 in the axial direction. The cover plate 47 includes a fixing plate 43, a support pin 44, and a coil spring 45 interposed therebetween.

As shown in FIG. 3B, the fixed plate 43 is a plate-like member provided along the outer periphery of the core member 20 (see FIG. 1). In the illustrated example, the fixing plate 43 includes a substantially semicircular base portion 43A along the outer periphery of the core member 20, a tongue piece portion 43B provided to protrude upward from the base portion 43A, and the base portion 43A and the tongue piece portion 43B. A through hole 43C formed through which the support pin 44 penetrates, and a notch 43T formed in the lower region of the base portion 43A and having the core member 20 disposed inside thereof. Therefore, the fixing plate 43 in the illustrated example can also be understood as a substantially arc-shaped plate material in which the core member 20 is disposed inside.
Further, the fixing plate 43 is provided along the circumferential direction on the outer periphery of the shaft member, and a portion along the outer peripheral surface of the shaft member that fixes the shaft member as it is inclined with respect to the axial direction of the shaft member. Can be understood as

Here, the through hole 43 </ b> C is a long hole whose longitudinal direction extends in the vertical direction, and is formed with a dimension that has a margin in the vertical direction with respect to the support pin 44 inserted therein. As a result, the relative position and angle of the fixing plate 43 with respect to the support pin 44 can change.
The base portion 43A is a part of the inner peripheral surface of the notch 43T (base portion 43A), and is a receiving surface 43E that is a flat surface formed at the center in the circumferential direction of the base portion 43A and the inner peripheral surface of the notch 43T. A substantially claw-shaped first claw portion 43F and a second claw portion 43G provided so as to protrude toward the center side from positions facing each other are provided. A side surface (upper side) of the first claw portion 43F facing the receiving surface 43E is a first claw receiving surface 43H, and a side surface of the second claw portion 43G is opposed to the receiving surface 43E. The side plane is referred to as a second claw receiving surface 43J.

3A again, the support pins 44 are arranged along the axial direction of the core member 20 with the center axis as a position spaced apart from the center axis of the core member 20. The coil spring 45, which is an example of an urging member that is a cylindrical member, is disposed at a position that is spaced upward from the central axis from the core member 20, that is, at a position that is not coaxial with the core member 20, And it arrange | positions along the axial direction of this core material 20. As shown in FIG. In the illustrated example, the support pin 44 is inserted into the coil spring 45 to be supported.

  The cover member 47, which is an example of a connecting member, is formed so as to fit into a support pin hole 47A into which the support pin 44 is inserted in the direction along the axial direction and a groove 41E of the holding member 41 provided at the lower end. The protrusion 47B formed, the groove 47C provided at the end on the back side so as to fit the protrusion 41D of the holding member 41, and the recess provided at the end on the back side so as to be immersed in the first direction. 47D and a notch 47T in which the core member 20 is disposed.

Now, the assembly process of the fixed unit 40 will be described with reference to FIG.
First, one end of the support pin 44 is inserted into the support pin hole 41 </ b> C of the holding member 41. Then, while passing the through hole 43C of the fixing plate 43, the coil spring 45, and the support pin hole 47A of the cover member 47 to the other end of the support pin 44, the protrusion 41D of the holding member 41 and the groove 47C of the cover member 47, The groove 41E of the holding member 41 and the protrusion 47B of the cover member 47 are fitted together (see FIG. 3A) and fixed by so-called press-fitting.
Thus, the substantially cylindrical fixing unit 40 in which the fixing plate 43, the support pin 44, and the coil spring 45 are sandwiched in the axial direction by the holding member 41 and the cover member 47 is assembled. In addition, the coil spring 45 arrange | positioned in this fixed unit 40 is a compression state.

Next, the arrangement of each member in the fixed unit 40 will be described.
First, the fixing plate 43 is urged in the second direction (see arrow D <b> 2) by the coil spring 45 and pressed against the inclined surface 41 </ b> A of the holding member 41. Along with this, the fixing plate 43 is disposed to be inclined with respect to the axial direction. More specifically, the fixing plate 43 is inclined in such a direction that the upper end portion is closer to the inlet side (left side in FIG. 3C) into which the core member 20 is inserted than the lower end portion.

  Further, the fixed plate 43 is rotatable in a direction in which an inclination angle (see angle α) with respect to the axial direction changes. Although the details will be described later, the fixed plate 43 has an inclined position along the inclined surface 41A (see the solid line fixed plate 43 in the figure) and an upright position having a larger inclination angle than the inclined position (see the broken line fixed plate 43 in the figure). It can be displaced between. Moreover, the fixing plate 43 can take the meshing position (refer the fixing plate 43 of Fig.4 (a)) which meshes with the core material 20 between an inclination position and a standing position.

  Further, inside the fixed unit 40, the through hole 41T of the holding member 41 and the notch 47T of the cover member 47 are continuously arranged in the axial direction so that the core member 20 can be inserted. Further, the notch 43T of the fixing plate 43 is also arranged so as to open into a space formed by the through hole 41T of the holding member 41 and the notch 47T of the cover member 47. In the illustrated example, the inlet side end 43K, which is the end of the core member 20 on the inlet side (left side in the figure) of the receiving surface 43E of the fixing plate 43, is positioned below the inclined surface 41A. That is, the inlet side end 43K is disposed so as to protrude into the space formed by the through hole 41T of the holding member 41 and the notch 47T of the cover member 47.

  Further, the holding member 41 and the cover member 47 form an opening 40 </ b> A on the upper side surface of the fixed unit 40 by the recess 41 </ b> F of the holding member 41 and the recess 47 </ b> D of the cover member 47 being continuous in the axial direction. Through this opening 40A, the tongue piece 43B of the fixing plate 43 provided inside the fixing unit 40 is exposed toward the upper side of the fixing unit 40.

  The fixed unit 40 is inserted into the second handle portion 13 in the assembled state as described above. Thereby, when mounting in the 2nd handle part 13, it is suppressed that the coil spring 45 is bounced etc., for example, and the installation work in the 2nd handle part 13 becomes easy. The fixed unit 40 can be replaced when the door handle 100 is maintained.

<Arrangement of Fixed Unit 40 and Core Material 20>
Next, the arrangement of each member in a state where the core member 20 is inserted into the fixed unit 40 will be described. 4A is a cross-sectional view in the axial direction in a state where the core member 20 is inserted into the fixed unit 40, and FIG. 4B is a cross-sectional view seen from IVb in FIG. 4A.

  First, as shown in FIG. 4A, when the core member 20 is inserted into the fixed unit 40 (see arrow D1), it is formed by the through hole 41T of the holding member 41 and the notch 47T of the cover member 47. The core member 20 is disposed in the space inside the fixed unit 40.

  In this state, as shown in FIG. 4B, the first member 21 of the core member 20 is arranged in the notch 43T of the fixing plate 43 (see FIG. 3B). More specifically, the receiving surface 43E, the first claw receiving surface 43H, and the second claw receiving surface 43J of the fixing plate 43 are respectively connected to the upper surface 21A, the first side lower surface 21B, and the second side lower surface 21C of the first member 21. Contact.

<Arrangement of Fixing Plate 43 and Core Material 20>
Here, the arrangement of the fixed plate 43 and the core material 20 in a state where the core material 20 is inserted into the fixed unit 40 will be described in detail. 5A is a perspective view for explaining the arrangement of the fixing plate 43 and the core member 20, and FIG. 5B is a cross-sectional view as seen from Vb in FIG. 5A. (C) is sectional drawing seen from Vc of Fig.5 (a).

  As shown in FIG. 5A, the fixing plate 43 is disposed so as to straddle the upper side of the core member 20 with the support pins 44 passing through the through holes 43C. The fixing plate 43 is biased by the coil spring 45 (see FIG. 4A) provided on the outer periphery of the support pin 44 as described above and tilted with respect to the axial direction. At this time, the fixed plate 43 is pressed around the through hole 43 </ b> C by the coil spring 45. In other words, in the fixed plate 43, only a partial region in the circumferential direction of the core member 20 is pressed by the coil spring 45.

  The fixed plate 43 that is urged by the coil spring 45 (see FIG. 4A) and is inclined with respect to the axial direction is in a state where the core member 20 is bitten. As a result, the core member 20 is fixed to the fixed unit 40. More specifically, as shown in FIG. 5B, the receiving surface 43E, the first claw receiving surface 43H, and the second claw receiving surface 43J of the fixing plate 43 are provided on the upper surface 21A of the first member 21. The fixed groove 21D, the fixed groove 21E provided on the first side lower surface 21B, and the fixed groove 21F provided on the second side lower surface 21C are brought into contact with each other.

  Therefore, in the cross section orthogonal to the axial direction, the fixing plate 43 fixes the core member 20 while pressing the core member 20 at three positions whose positions in the circumferential direction of the core member 20 are different. In other words, one of the three locations including the receiving surface 43E, the first claw receiving surface 43H, and the second claw receiving surface 43J of the fixed plate 43 is replaced with the other two of the three locations. By pressing the first member 21 of the core member 20 toward the fixing plate 43, the fixing member 43 fixes the core member 20. More specifically, the receiving surface 43E, the first claw receiving surface 43H, and the second claw receiving surface 43J of the fixing plate 43 are pressed toward the center side of the first member 21 of the core member 20 (arrows F1, F1). (Refer F2 and F3), the shift | offset | difference in the left-right direction in the figure of the core material 20 is also suppressed.

  The fixing plate 43 is not a so-called annular member but can be regarded as a substantially arc-shaped member, and the lower side of the fixing plate 43 is not continuous in the circumferential direction and is notched 43T (see FIG. 3C). Has been released by. The fixing plate 43 holds the first member 21 so that only the first member 21 is held in a state where the core member 20 is bitten. In other words, the fixing plate 43 presses the outer peripheral surface of the first member 21 when the core member 20 is fixed, but is separated from the outer peripheral surface of the second member 23.

  As described with reference to FIG. 2C, the core member 20 can be elastically deformed in the vertical direction. For example, depending on the dimensions of the resin cover 55 and the cam hole, The dimensions can vary. Here, unlike the present embodiment, assuming a configuration in which the fixing plate 43 holds both the first member 21 and the second member 23 constituting the core member 20, for example, in the vertical direction of the core member 20. When the dimension is too large, the core material 20 cannot be inserted into the fixed plate 43. On the other hand, when the fixing plate 43 is held so as to hold only the upper member (first member 21) in the core member 20 as in the present embodiment, even if the vertical dimension of the core member 20 changes. The core material 20 is reliably arranged in the notch 43T.

  Further, the fixing plate 43 is provided on the upper outer periphery of the core member 20 and is not disposed on the lower outer periphery, and the outer dimension in the vertical direction is suppressed. Here, from the viewpoint of securing the strength of the core material 20, it is desired to increase the thickness of the core material 20, whereas from the viewpoint of design, the shaft portion 13 </ b> B of the second handle portion 13 (FIG. 1). It may be desired to reduce the diameter of the reference). In this case, the space for disposing the fixing plate 43 in the shaft portion 13B of the second handle portion 13 is reduced. However, the fixing plate 43 in which the outer dimension in the vertical direction is suppressed can be disposed in this space. As a result, the degree of freedom of design increases.

  Next, changes in the arrangement of the fixing plate 43 and the core material 20 when the core material 20 is inserted into the fixed unit 40 will be described with reference to FIG. First, as described above, the fixed plate 43 is displaced between the tilt position and the standing position by changing the tilt angle (see angle α), and the meshing position between the tilt position and the standing position. Can take. At the meshing position (see the solid fixed plate 43 in the figure), the fixed plate 43 meshes with the core member 20 as described above, and the axial movement of the core member 20 is restricted. On the other hand, in the standing position (see the fixed plate 43 indicated by a broken line in the figure), the fixed plate 43 is released from meshing with the core member 20 and can move in the axial direction of the core member 20.

Here, in a state where the core member 20 is not disposed in the fixed unit 40, the fixed plate 43 is disposed at an inclined position by the coil spring 45.
As the core material 20 is inserted into the fixed unit 40, the core material 20 enters the notch 43 </ b> T of the fixed plate 43. At this time, the core member 20 stands up against the elastic force of the coil spring 45 by engaging with the periphery of the notch 43T of the fixing plate 43 (for example, the inlet side end 43K of the fixing plate 43). Move to position. Therefore, the receiving surface 43E, the first claw receiving surface 43H, and the second claw receiving surface 43J of the fixing plate 43 are engaged with the upper surface 21A, the first side lower surface 21B, and the second side lower surface 21C of the first member 21, respectively. In a state in which is released, the core member 20 pushes through the notch 43T.

  Then, for example, when the core 20 reaches a predetermined position, for example, when the first handle portion 11 (see FIG. 1) into which the core 20 is inserted hits the first base material 33 (see FIG. 1). Since the pressing force by the core material 20 disappears, the fixing plate 43 meshes with the core material 20 at the meshing position in the process of returning to the inclined position side again. As a result, the movement of the core member 20 is restricted.

  More specifically, in this state, when the core member 20 is to be pulled out (see arrow D2), the fixing plate 43 disposed at the meshing position is pressed in the direction opposite to the standing position where the fixing of the core member 20 is released. The receiving surface 43E, the first claw receiving surface 43H, and the second claw receiving surface 43J of the fixing plate 43 receive the force to be caused from the core member 20, and the upper surface 21A, the first side lower surface 21B, and the second side lower surface of the first member 21. The force that meshes with each of the 21Cs becomes stronger.

  In the present embodiment, the fixed plate 43 is pressed around the through hole 43C by the coil spring 45 (see arrow F5). In other words, the upper end of the fixed plate 43 is pressed in the second direction (see arrow D2) by the coil spring 45, and the lower end of the fixed plate 43 is not pressed in the second direction. Accordingly, the coil spring 45 applies only a force for urging the fixed plate 43 to be in the inclined position, and urges the fixed plate 43 to the standing position (moment in a direction opposite to the urging force toward the inclined position). Is not added. That is, the coil spring 45 presses only a portion necessary for arranging the fixing plate 43 at the inclined position.

  As a result, it is avoided that a force is applied by the coil spring 45 in the direction in which the fixed plate 43 is erected, that is, the direction in which the fixed plate 43 releases the core member 20, and the fixed core member 20 is prevented from loosening. . Even if it is necessary to change the elastic force of the coil spring 45 in order to adjust the force for urging the fixing plate 43, the coil spring 45 has a moment in the direction opposite to the urging force toward the inclined position. Is not added to the fixing plate 43, so that the elastic force can be easily adjusted.

Next, the arrangement of the fixing plate 43 and the core member 20 when the core member 20 fixed in the fixing unit 40 is pulled out will be described. 6A is a cross-sectional view in the axial direction in a state where the core member 20 is pulled out in the fixed unit 40, and FIG. 6B is a cross-sectional view seen from VIb in FIG. 6A.
As illustrated in FIG. 6A, when the core member 20 fixed in the fixing unit 40 is pulled out, the inclined surface 41 </ b> A and the tongue piece portion 43 </ b> B of the fixing plate 43 are extracted from the operation window 13 </ b> D of the second handle portion 13. An operation tool 95 such as a driver is inserted in a gap with respect to (see FIG. 3B). Then, the operation tool 95 raises the fixed plate 43 to the standing position.

  Then, as shown in FIG. 6 (b), the receiving surface 43E, the first claw receiving surface 43H, and the second claw receiving surface 43J of the fixing plate 43 are connected to the upper surface 21A, the first lower surface 21B, and the first side lower surface 21B. The fixing plates 43 release the core member 20 from the second side lower surface 21C. In this state, the core member 20 is pulled out from the fixed unit 40.

<Modification>
Next, a modification of the above embodiment will be described. FIG. 7A is a diagram for explaining a modification of the fixing plate 43, and FIG. 7B is a diagram for explaining a modification of the core member 20.

First, as in the fixing plate 430 shown in FIG. 7A, at least one of the receiving surface 430E, the first claw receiving surface 430H, and the second claw receiving surface 430J protrudes from the respective surfaces toward the center side. The structure provided with the protrusion (groove) may be sufficient. That is, sawtooth-shaped irregularities may be provided on the receiving surface 430E, the first claw receiving surface 430H, and the second claw receiving surface 430J.
Thus, by providing the receiving surface 430E, the first claw receiving surface 430H, and the second claw receiving surface 430J with saw-toothed irregularities, the frictional force with the core material 20 is increased, and the fixing plate 430 causes the core material 20 to move. The holding force is improved.

  In the above description, the fixing plate 43 is described as having a substantially semicircular base portion 43A. However, the shape is limited to this shape as long as the notch 43T is formed on the lower side. Of course, other shapes such as a substantially rectangular shape may be used.

  Next, instead of the fixing grooves 21D, 21E, and 21F as in the core member 200 shown in FIG. 7 (b-1), the respective surfaces may be rough grain surfaces 210D and 210F. That is, the receiving surface 43E of the fixing plate 43 and the first nail support are increased by increasing the surface roughness (for example, arithmetic average roughness Ra) as compared with other portions of the core member 200 (by performing rough surface processing). The structure which increases the frictional force with the surface 43H and the 2nd nail | claw receiving surface 43J may be sufficient.

  Alternatively, like the core material 210 shown in FIG. 7 (b-2), the entire outer peripheral surface is a rough grained surface, and by increasing the surface roughness of the entire outer peripheral surface than before applying the rough surface processing, The structure which ensures the frictional force with the fixed plate 43 may be sufficient.

  In addition, it is not necessary to form the fixing groove 21D or the like or the rough grain surface 210D or the like in the core member 20. That is, as in the core material 220 shown in FIG. 7B-3, a configuration in which the core material 220 is not subjected to special surface processing may be used. For example, like the fixing plate 430 shown in FIG. 7A, sawtooth-like irregularities are formed on the receiving surface 430E, the first claw receiving surface 430H, and the second claw receiving surface 430J, so that the fixing plate 430 In the configuration in which the frictional force generated between the core members 220 is large, a configuration in which the core material 220 is not subjected to special surface processing can be employed.

The core member 20 in the above description is a long member having a substantially square cross section, and can be regarded as a member having a substantially V-shaped cross section and grooves (concave portions) along the axial direction formed on the side surfaces. The core member 20 can be regarded as a configuration in which the fixing grooves 21D, 21E, and 21F are formed on the upper surface and the upper surface of the groove having a substantially V-shaped cross section. Moreover, the 1st nail | claw part 43 (convex part) F and the 2nd nail | claw part 43G can be grasped | ascertained as a structure concerning this V-shaped groove | channel.
In the above description, it has been described that the core member 20 has the two members of the first member 21 and the second member 23. However, the core member 20 may be constituted by a single member. In addition, as long as a frictional force is ensured between the fixing plate 43 and the cross-sectional shape of the core member 20, the shape may of course be other shapes such as a square.

  In the above description, it has been described that the fixing plate 43 supports the core member 20 at three locations. However, if the configuration is such that the movement in the direction intersecting the axial direction of the core member 20 is suppressed, there are four locations. The structure supported by the above may be sufficient.

  Furthermore, in the above description, it has been described that the first handle portion 11 and the second handle portion 13 provided with the indoor door 1 interposed therebetween, but either one of the first handle portion 11 and the second handle portion 13 is provided. And the other may be constituted by a bearing or the like without a handle. In addition to the indoor door 1, the door handle 100 may of course be used for furniture such as outdoor doors and windows, or furniture such as storage shelf doors.
