As shown in figure 17, the pressing portion 43b of upper frame 16 further pushes ring 12, and bar-like member 11 passes through gap as a result, 113 and be inserted into the inside that the arcus part 111 of flexible deformation has occurred.It is disconnected from each other when bar-like member 11 passes through gap 113 Two ends 112,112 between restore to original position, the protrusion 114 of ring 12 is inserted into slot 102.

During bar-like member 11 passes through gap 113, the antetheca 33 of movable member 15 across ring 12 by by the ring 12 to The pressing portion 43b for the upper frame 16 that lower direction pushes further is pushed.As a result, being assemblied in the shape in slot 102 in ring 12 Under state, the edge 33c of antetheca 33 is moved to except slot 102.Therefore, relieve by antetheca 33 realized to bar-like member 11 in axis The limitation moved up.

As described above, the edge 33c of antetheca 33 includes two extended parallel to from the 33a of end face to the positive direction along Z axis Part；And connect the part of the arc-shaped of two parts.Therefore, even if the part of the arc-shaped of edge 33c runs off slot 102 Except, in the case where two extended parallel to of slot 33c are partially in slot 102, antetheca 33 can also limit bar-shaped portion Part 11 moves in the axial direction.In other words, by running off antetheca 33 to the position except slot 102 from the part of the arc-shaped of edge 33c Further mobile defined distance has been set, the limitation moved in the axial direction to bar-like member 11 is released.

The close folded column portion 17 of above frame 16 as described above, lower frame 14 close to each other and folded column portion 17 are supported rodlike Component 11, movable member 15 antetheca 33 edge 33c be located at except the slot 102 of bar-like member 11, two ends 112 of ring 12, 112 are defined as rigging position P4 by the position of each section of the ring assembly device 10 in the state of the bearing of movable member 15.About Folded position of the column portion 17 relative to lower frame 14, it is identical in ring bearing position P3 and rigging position P4.

Radius Rs ratio until the 1st rotation center Ax1 to the end face 33a of antetheca 33 shown in Fig. 3 is from the 2nd rotation center Radius Rp until Ax2 to the pressing portion 43b for pushing plate 43 is small.Therefore, until from ring bearing position P3 to rigging position P4 In section, movable member 15 around the 1st rotation center Ax1 rotation angle than upper frame 16 around the rotation of the 2nd rotation center Ax2 Angle is big.Therefore, the edge 33c of the antetheca 33 of movable member 15 rapidly deviates from from the slot 102 of bar-like member 11.

Figure 19 is ring the assembly a part of device 10, a part of bar-like member 11, Yi Jiwei for showing the 1st embodiment Set the illustrative main view for the ring 12 being staggered.Figure 20 is a part, rodlike for showing the ring assembly device 10 of the 1st embodiment The illustrative cross-sectional view for the ring 12 that a part of component 11 and position are staggered.

Ring assembles device 10 by user's holding as the mankind.Moreover, bar-like member 11 can similarly be kept by user. Therefore, when user's operation ring assembles device 10, the hand of the user for example can be due to firmly occurring shake (trembling).Due to this It trembles, ring assembly device 10 and bar-like member 11 relatively may slightly move in the axial direction of bar-like member 11.It is assembling The edge 33c of position P4, antetheca 33 are located at except slot 102, therefore ring assembly device 10 and bar-like member 11 can be in bar-like members It is relatively moved in 11 axial direction.

In the axial direction of bar-like member 11, the rear phase of the abutment wall 23b of lower frame 14 in the antetheca 33 of movable member 15 It is adjacent.Since ring 12 is contacted with abutment wall 23b, it limits and is equipped with the bar-like member 11 of ring 12 and rearward moves.It is another Aspect, the bar-like member 11 for being equipped with ring 12 can move forwards.

As shown in figure 20, when bar-like member 11 is (forwards) mobile in the axial direction, in the axial direction, it is assemblied in bar-shaped portion The position of the ring 12 of part 11 and the position of the end face 33a of the antetheca 33 supported to the ring 12 are staggered.That is, bearing movable member 15 ring 12 is disengaged from the movable member 15, which is twisted spring 97 around the 1st rotation center Ax1 to the inverse of Figure 20 Clockwise pushes.Therefore, the rotating counterclockwise to Figure 20 due to torsionspring 97 of movable member 15.In other words, movably The rotation wall 31 of component 15 is mobile towards lower frame 14.

The rotation wall 31 of the movable member 15 rotated by torsionspring 97 and the screw 25 of lower frame 14 are collided and are issued Sound.According to the sound, user is able to know that in the state that assembly of the ring 12 relative to slot 102 has been completed.Also, such as It is also possible to rotate the bottom wall 21 of the collision lower frame 14 of wall 31 or antetheca 33 collides the circumferential surface 101 of bar-like member 11, thus It makes a sound.

Knowing the user in the state that assembly of the ring 12 relative to slot 102 is completed can be by bar-like member 11 under It is extracted between frame 14 and folded column portion 17.If user releases operation to handle 19, ring assemble each section of device 10 by 1st and the 2nd cut spring 95,96 returns to initial position P1.In initial position P1, lower frame 14 is separated from folded column portion 17.Therefore, User can easily unload the bar-like member 11 for being equipped with ring 12 from ring assembly device 10.

About the linkage mechanism M acted as described above, pass through the position to arm 34,44,93, rotation center Ax1 The position of~Ax3, the 1st cut spring 95, the position of the 2nd cut spring 96 and torsionspring 97 and coefficient of elasticity are set It is fixed, can suitably set lower frame 14, movable member 15, upper frame 16 and the actuating range in folded column portion 17, action moment or Person's movement speed etc..For example, in the present embodiment, adjusting the technical parameter (spec) of each section as follows: in ring 12 Two ends 112,112 and the end face 33a of antetheca 33 at the time of contact after, make movable member 15 to rigging position P4's Movement starts.

As shown in Figure 1, being respectively equipped with guiding groove 121 on two lateral walls 42 of upper frame 16.Guiding groove 121 is on edge The hole that the side of Z axis upwardly extends.Moreover, leading axle 122 is installed in folded column portion 17.Leading axle 122 prolongs on the direction along Y-axis It stretches, and penetrates through guiding groove 121.As clockwise side of the upper frame 16 relative to folded column portion 17 around the 2nd rotation center Ax2 into Fig. 3 To when rotation, leading axle 122 moves in guiding groove 121.Such guiding groove 121 and leading axle 122 to upper frame 16 and are folded The rotation in column portion 17 guides.

In the ring assembly device 10 of the 1st embodiment, folded column portion 17 be arranged on bar-like member 11 with lower frame 14 Opposite side.Folded column portion 17 supports bar-like member 11, and thus bar-like member 11 is maintained between folded column portion 17 and frame 14. That is, lower frame 14 and folded column portion 17 keep bar-like member 11 from both direction (in the present embodiment for above and below).It should Folded column portion 17 is configured to: can dividually be moved relative to lower frame 14 with the upper frame 16 pushed to ring 12.As a result, When the pressing portion 43b of upper frame 16 pushes ring 12, bar-like member can be kept using lower frame 14 and folded column portion 17 11.Therefore, the position that bar-like member 11 is able to suppress in a period of ring 12 is assemblied in slot 102 shifts, so as to Inhibit the increase of the power because of caused by the positional shift of bar-like member 11 for being pushed to ring 12 or the deformation of ring 12.

1st track 51 and the 2nd track 52 in folded column portion 17 are propped up in the circumferentially spaced adjacent with gap of bar-like member 11 Hold bar-like member 11.Folded column portion 17 supports bar-like member 11 by the 1st and the 2nd track 51,52, thus keeps bar-like member 11 Folded between column portion 17 and lower frame 14.That is, the 1st and the 2nd of the concave surface 23a of the abutment wall 23b of lower frame 14 and folded column portion 17 the Track 51,52 keeps bar-like member 11 at three points.The folded column portion 17 is configured to: can with ring 12 is pushed it is upper Frame 16 is dividually relatively moved with lower frame 14.As a result, when the pressing portion 43b of upper frame 16 pushes ring 12, energy Enough bar-like member 11 is kept using lower frame 14 and the 1st and the 2nd track 51,52 in folded column portion 17.Therefore, it is assemblied in ring 12 The position that bar-like member 11 is able to suppress in a period of slot 102 shifts, so as to inhibit the position because of bar-like member 11 The increase of power caused by offset for being pushed to ring 12 or the deformation of ring 12.Moreover, because supporting at three points Bar-like member 11, therefore be able to suppress kept bar-like member 11 and move radially.

1st cut spring 95 pushes lower frame 14 to the direction far from folded column portion 17, and the 2nd cut spring 96 is by upper frame 16 push to the direction far from folded column portion 17.That is, lower frame 14, the 1st cut spring 95, folded column portion 17,96 and of the 2nd cut spring Upper frame 16 is sequentially connected.The coefficient of elasticity of 2nd cut spring 96 is higher than the 1st cut spring 95.It is for example filled as a result, in ring With device 10 be user-operably and make lower frame 14, folded column portion 17 and upper frame 16 it is close to each other in the case where, firstly, folded column portion 17 and lower frame 14 it is close to each other, then, upper frame 16 and folded column portion 17 are close to each other, 43b pairs of the pressing portion of frame 16 on this Ring 12 is pushed.That is, in the concave surface 23a of the abutment wall 23b of lower frame 14 and 51,52 pairs of the 1st and the 2nd track in folded column portion 17 After bar-like member 11 is kept, ring 12 is assemblied in slot 102 by the pressing portion 43b of upper frame 16.Therefore, it is filled in ring 12 Assigned in front of slot 102 and during ring 12 is assemblied in slot 102, the position for being able to suppress bar-like member 11 shifts, thus It is able to suppress the increase of the power because of caused by the positional shift of bar-like member 11 for being pushed to ring 12 or the change of ring 12 Shape.

Lower frame 14, upper frame 16, folded column portion 17 are rotated around same 2nd rotation center Ax2.It is multiple that no setting is required as a result, Rotary shaft is able to suppress the increase of the number of components of ring assembly device 10.

Radius Rsp1 ratio until the 2nd rotation center Ax2 to the 1st cut spring 95 is from the 2nd rotation center Ax2 to the 2nd Radius Rsp2 long until cut spring 96.Therefore, to the lower frame 14, the 1st cut spring 95, folded column portion sequentially connected 17, in the case that the 2nd cut spring 96 and the input of upper frame 16 have such power close to each other, the 1st cut spring is acted on 95 power is compared to big for the power of the 2nd cut spring 96.Therefore, more reliably by the 1st and the 2nd of lower frame 14 and folded column portion 17 the Track 51,52 first keeps bar-like member 11, and ring 12 is then assemblied in slot 102 by the pressing portion 43b of upper frame 16.Therefore, exist Ring 12 is able to suppress bar-like member 11 position in a period of being assemblied in slot 102 shifts, so as to inhibit because rodlike The increase of power caused by the positional shift of component 11 for being pushed to ring 12 or the deformation of ring 12.

Ring 12 is stored in folded column portion 17 with the 1st and the 2nd track 51,52.Therefore, in lower frame 14 and folded column portion When 17 the 1st and the 2nd track 51,52 remains bar-like member 11, the ring 12 in folded column portion 17 is accommodated in relative to bar-like member 11 It is configured in defined position (in the present embodiment, in face of the position of slot 102).Pressing portion 43b is to being configured at the position Ring 12 pushed, thus ring 12 is assemblied in slot 102.Thereby, it is possible to inhibit the shifting of the ring 12 pushed by pressing portion 43b Dynamic distance increases, and shifts in the position that the midway pushed by pressing portion 43b is able to suppress ring 12.

1st track 51 and the 2nd track 52 extend parallel to.Side with the 1st and the 2nd track 51,52 to cross one another as a result, The case where formula extends compares, even if bar-like member 11 is deviated in the axial direction, lower frame 14 and folded column portion 17 the 1st and 2nd track 51,52 can also stably keep bar-like member 11 at three points.Moreover, because bar-like member 11 is by abutment wall The concave surface 23a of 23b and the 1st and the 2nd track 51,52 are kept, therefore the direction of the 1st and the 2nd track 51,52 extension and bar-like member 11 it is axially substantially parallel.The the 1st and the 2nd track 51,52 is contacted with 11 line of bar-like member or face contact respectively as a result, and the 1st and 2 tracks 51,52 can more stably keep bar-like member 11.

A part of 1st track 51 and a part of the 2nd track 52 be inserted respectively into addition in face of opening 74 ring 12 it In the gap 113 of outer multiple rings 12.That is, the 1st and the 2nd track 51,52 is used as making the respective gap 113 of multiple rings 12 Towards the guiding piece of alignment.By making such 1st and the 2nd track 51,52 keep bar-like member 11, without separately setting guidance Part is able to suppress the enlargement of ring assembly device 10.

The edge 33c of the antetheca 33 of movable member 15 is inserted into slot 102.As a result, by the concave surface 23a of abutment wall 23b and 1st and the 2nd track 51,52 is able to suppress bar-like member 11 and moves radially, and is able to suppress by the edge 33c of antetheca 33 Bar-like member 11 moves in the axial direction.

In mode close to each other elastic change can occur for the 1st and the 2nd flexible portion 87,88 supported to pressure spring 84 Shape, wherein the pressure spring 84 pushes multiple rings 12 towards retaining wall 73 is held.Therefore, by by the 1st and the 2nd flexible portion 87,88 with Mode close to each other is configured between two fixing walls 71 in the state that flexible deformation has occurred, and the 1st and the 2nd is flexible as a result, Portion 87,88 flexibly and is simply fastened in two clamping holes 78.

Torsionspring 97 pushes movable member 15 towards lower frame 14.Screw 25 contacts to limit with movable member 15 It is twisted the movement of the movable member 15 of the pushing of spring 97.The movable member 15 is across ring 12 by the pressing portion 43b of upper frame 16 It pushes, is thus separated from bar-like member 11 and screw 25 to direction intersecting axially, wherein the pressing portion of the upper frame 16 43b pushes the ring 12 to the direction (lower section) axially intersected with bar-like member 11.Therefore, movable member 15 is by pushing Portion 43b and ring 12 are twisted spring 97 in the state of the separation of screw 25 and push towards lower frame 14.

The upper ledge that movable member 15 is pushed the ring 12 to the direction axially intersected with bar-like member 11 across ring 12 The pressing portion 43b of frame 16 is pushed, and the edge 33c of antetheca 33 is moved to except slot 102 as a result,.That is, the axial direction to bar-like member 11 is moved The edge 33c of the dynamic antetheca 33 limited deviates from from slot 102, therefore bar-like member 11 can move in the axial direction.With in slot The bar-like member 11 that ring 12 is equipped in 102 moves in the axial direction, and the ring 12 pushed to movable member 15 is inclined in the axial direction It moves.Since the ring 12 of bearing movable member 15 is removed, the movable member 15 for being twisted the pushing of spring 97 collides screw 25 And it makes a sound.Also, it is also possible to make a sound and making movable member 15 collide bar-like member 11.

In the case where the user as the mankind operates ring assembly device 10, the user's assembles device 10 to ring Shake (trembling) may be generated with what bar-like member 11 was kept.This, which trembles, can generate bar-like member 11 in the axial direction slightly Micro-shifting is dynamic.Therefore, even if user is not still, to be assemblied in slot 102 from ring 12 it is intended that bar-like member 11 moves in the axial direction It rises and passes through small time lag, movable member 15 may collide screw 25 and make a sound.

As described above, it collides screw 25 by movable member 15 to make a sound, as a result, the user of ring assembly device 10 It is able to know that in the state for completing assembly of the ring 12 relative to slot 102.As described above, due to being assemblied in from ring 12 There is only small time lags during slot 102 rises until making a sound, therefore, it can be stated that, user, which is able to know that, to be completed Assembly of the ring 12 relative to slot 102.

In addition, movable member 15 is pushed across ring 12 by pressing portion 43b, thus from bar-like member 11 to intersecting axially Direction separation.In the case where ring 12 is not assemblied in slot 102, a part of the edge 33c of the antetheca 33 of movable member 15 is kept The state that is inserted into slot 102 and the movement of bar-like member 11 in the axial direction can be limited.That is, in ring 12 relative to slot 102 In the case that assembly does not complete, the ring 12 for being able to suppress the midway being for example inserted into slot 102 deviates in the axial direction, so as to press down System makes a sound in the state of the midway that ring 12 is inserted into slot 102.

Screw 25 is set to lower frame 14.Screw 25 is formed without using the component except lower frame 14 as a result, it can Inhibit the enlargement of ring assembly device 10.

Radius Rs ratio until the end face 33a of the antetheca 33 of the 1st rotation center Ax1 to movable member 15 is rotated from the 2nd Radius Rp until center Ax2 to pressing portion 43b is small.It is when therefore, to 102 mounting ring 12 of slot, across ring 12 by pressing portion 43b The angle that the antetheca 33 of the movable member 15 of pushing is rotated is bigger than the angle that the pressing portion 43b of upper frame 16 is rotated.Therefore, (rotation) can fully be left from screw 25 by the movable member 15 that pressing portion 43b is pushed across ring 12, so as to touch It is issued when hitting screw 25 and is able to use the sound that family fully identifies.

In the present embodiment, the abutment wall 23b of lower frame 14 and the antetheca 33 of movable member 15 for example can be by synthesizing It is capable of the material production of flexible deformation as rubber.According to such abutment wall 23b, the radius energy of the concave surface 23a of arc-shaped It is enough to expand.Moreover, the radius of the edge 33c of arc-shaped can expand according to such antetheca 33.Therefore, abutment wall 23b and antetheca 33 can the different a variety of bar-like members 11 of pair radius supported.

Hereinafter, referring to Figure 46 to Figure 50, the 4th embodiment is illustrated.Also, the ring of present embodiment assembles device 10 have structure identical with the ring of the 1st embodiment assembly device 10.In the explanation of the following embodiments and the accompanying drawings, exist as follows Situation: for the constituent element with function same as the constituent element having been described that, label has been described with this The identical label of constituent element, and omit the description.In addition, the multiple constituent elements for being marked with identical label be not limited to it is all The function situation identical with property, it is possible to have corresponding from each embodiment different function and property.

Figure 46 is the schematical and illustrative side view of the ring assembly device 10 of the 4th embodiment.In addition, Figure 47 is The schematical and illustrative side view of the ring assembly device 10 of 4th embodiment, and be greatly exaggerated to show due to operation The holding power of member and the figure of state deformed.

After ring 12 has just been assemblied in bar-like member 11, as shown in figure 46, ring 12 and bar-like member 11 are by upper frame End folder on the length direction of (right of Figure 46, an X-direction) end and lower frame 14 on 16 length direction Firmly.In addition, as described above, another (left of Figure 46, the opposite direction of X-direction) end on the length direction of upper frame 16 and Another end on the length direction of lower frame 14 is by the 2nd axis 47 (linking part) can rotate around the 2nd rotation center Ax2 Mode combine.

Therefore, as shown in figure 47, when operator further assembles support ring after ring 12 is assemblied in bar-like member 11 When device 10, as shown in figure 47, it is applied to the pushing power F for holding associated by the upper frame 16 in the state of two supports Centre portion, and be applied to associated pushing power F is held by the central portion of the lower frame 14 in the state of two supports.Push power F applies via handle 19 (referring to Fig.1,3 etc.), therefore becomes bigger value.

Here, as shown in figure 3,22 phase of inner sidewall of (X-direction) end on the length direction of lower frame 14 It is lower relative to the height of bottom wall 21 than the inner sidewall 22 at the other parts of lower frame 14 for the height of bottom wall 21.Therefore, under The rigidity of an end (in the region B in Figure 47) on the length direction of frame 14 is lower than the other parts of lower frame 14.Cause This, such as in the pushing power F associated with the holding of operator excessive situation etc., as shown in figure 47, bottom wall 21 is easily deformed For towards the state of 16 protrusion of upper frame.

Inventor is by obtaining following discovery for the further investigation of such deformation: using constant one of specification When ring assembles device 10, in the case where ring 12 is assemblied in thicker (being relatively large in diameter) bar-like member 11, with operator It holds associated pushing power F and easily becomes excessive state.The discovery is illustrated, bar-like member 11 is supported in lower frame On 14.Therefore, bar-like member 11 is thicker, then the ring 12 being assemblied on bar-like member 11 is located the position far from lower frame 14. Therefore, bar-like member 11 is thicker, then in a period of holding until ring 12 is assemblied in bar-like member 11 since operator The distance (hereinafter, being set as practical moving distance) that upper frame 16 is relatively moved relative to lower frame 14 is shorter.In contrast, operation Member has the tendency with the thickness of bar-like member 11 independently constant to the operating quantity of handle 19.Accordingly, there exist following tendencies: Hold since the operator until holding and completing, upper frame 16 relative to the distance to be relatively moved of lower frame 14 (hereinafter, It is set as operating distance) it is independently constant with the thickness of bar-like member 11.As described above, bar-like member 11 is thicker, then it is practical mobile Distance is shorter, therefore, unrelated with the thickness of bar-like member 11 if keeping operating distance constant: bar-like member 11 is thicker, Ring 12 be assemblied in after bar-like member 11 upper frame 16 correspond to operator to the holding of handle 19 want it is further movement of away from It is longer from (hereinafter, being set as more than with a distance from).It is longer more than distance, it pushes power F and more tends to get bigger.Therefore, it is assemblied in ring 12 It in the case where thicker bar-like member 11, is easy more than distance elongated, in turn, holds with the associated pushing power F of holding of operator Mutability is at excessive state.

Therefore, the ring assembly device 10 of present embodiment is constituted are as follows: it is at the time of ring 12 is assemblied in bar-like member 11, on Frame 16 and the relative position of lower frame 14 are constant and unrelated with the thickness of bar-like member 11.Bar-shaped portion is assemblied in for ring 12 The relative position of at the time of part 11, upper frame 16 and lower frame 14, such as can be described as frame 16 and lower frame 14 in nothing Frame be equipped under the state (state that pole lightly clips) of the bar-like member 11 of ring 12, upper is clipped in the case where contact face pressure 16 with the relative position of lower frame 14.Relative position for example according to as shown in Figure 46, push plate 43 and ring 12 contact position It sets (front end, such as recess portion 43c, referring to Figure 49) and pushes the distance between plate 43 and lower frame 14 Ls to measure.Also, phase Position can also be measured according to the distance different from distance Ls, can also be surveyed according to the angle around the 2nd rotation center Ax2 ?.
