In addition, sliding cam parts 20 also left and right symmetrically are located on the upper surface of a 2a, are provided with the joint pin 11, locking external cam 12 and the rib 13 that engage with sliding cam parts 20 above main part 6.
Dispose cam lever 31 in the slot part 21 of the sliding cam parts 20 on the lower surface that is equipped on a 2a.Cam lever 31 is opposite to locking external cam 12 and disposes, and is that center of rotation is rotated with the 2nd axial region 32b that is supported on the crank axle 32 (with reference to Fig. 5) on the 2a.
Fig. 5, Fig. 6, Fig. 7 are the positive view of the lower left quarter of expression door 2a, last cutaway view and sectional view.In addition, Fig. 8 is the A-A cutaway view of Fig. 5.Handle 5 is embedded in 51 supports of axle in the bearing 7 that is located on the 2a, and a part is accommodated in the recess 2b that is located on the 2a.Thus, handle 5 is a turning cylinder with axle 51, forwards spurs and rotates by controlling operating portion 5a.
The recess 2b that is located on the 2a forms wall by the door cap 58 that is made of resin forming product.On the door cap 58 of the lower surface inwall that forms recess 2b, be formed with the circular-arc 58a of hole portion (the 1st retainer is with reference to Figure 14).Near the axle 51 of door cap 58, be equipped with fastener 58b (the 2nd retainer).On axle 51, insert and be connected with torsionspring 55.Torsionspring 55 is clamped between the inwall and fastener 58b of handle 5, makes the handle 5 of rotation get back to original position.
Figure 10 (a), Figure 10 (b) are vertical view and the front views that the expression handle is strengthened angle 53.Handle is strengthened angle 53 and is made of metallic plate, is installed on the front of handle body portion 52 and handle 5 is strengthened.On an end at handle reinforcement angle 53, be formed with the inserting hole 53a that inserts axis 51.With respect to inserting hole 53a and operating portion 5a same side, be provided with the slotted hole 53b of the 1st axial region 32a (with reference to Figure 12) that inserts logical crank axle 32.
Figure 11 (a)～Figure 11 (c) is vertical view, front view and the side view of expression handle decorative panel 54.Handle decorative panel 54 is made of resin forming product, and the engaging pawl 54a that is darted at rear side is engaged among the connecting hole 52b (with reference to Fig. 9), and is installed in the handle body portion 52.
Figure 12 is the front view of expression crank axle 32.Crank axle 32 forms metal bending, has parallel the 1st, the 2nd axial region 32a, 32b.Be formed with in the lower end of the 2nd axial region 32b to the bend 32c of the 1st axial region 32a rightabout bending.Cam lever 31 (with reference to Fig. 6) is installed on bend 32c, and cam lever 31 vertically is provided with respect to the 2nd axial region 32b.In addition, by the crooked lower end that makes the 1st axial region 32a and the continuous continuous 32d of portion in lower end of the 2nd axial region 32b of forming.
The 1st axial region 32a inserts logical and fits loosely in handle and strengthens among the slotted hole 53b at angle 53, constitutes the linking part that handle 5 and crank axle 32 are linked.By handle and cam lever 31 being linked, handle 5 can be configured on the position of the expectation of leaving up and down from cam lever 31 and the raising convenience with arranged opposite around the main part 6 with crank axle 32.
On door 2a, below handle 5, be provided with shaft-cup 56.Figure 13 (a)～Figure 13 (c) is vertical view, front view and the side view of expression shaft-cup 56.Shaft-cup 56 is made of resin forming product, can be filled in Foamex in the 2a and hide and insert logical crank axle 32.
Be provided with the 1st roughly fan-shaped spatial portion 56b that overlooks that the 2nd axial region 32b can rotate on the top of shaft-cup 56.Be provided with the 2nd spatial portion 56c of the fitting portion 56a with cross section U font in the bottom of shaft-cup 56.Rotate the 2nd axial region 32b (support portion) that supports crank axle 32 freely by fitting portion 56a.Thus, to constitute by the rotation of handle 5 with the 2nd axial region 32b be the rod unit 30 that center of rotation is rotated to crank axle 32 and cam lever 31.
In addition, as shown in figure 14, the 58a of hole portion of door cap 58 forms concentric circular-arc with the 2nd axial region 32b, inserts logical the 1st axial region 32a.Under handle 5 was accommodated in state among the recess 5b, the 1st axial region 32a was provided on the end of dark side of the 58a of hole portion.If crank axle 32 rotates, then the 1st axial region 32a slides in the 58a of hole portion.
In the door open/close machine of said structure, if the operating portion 5a of pull handle 5, then operating physical force is delivered to the 1st axial region 32a via slotted hole 53a, and the 1st axial region 32a forwards rotates in the 1st spatial portion 56b.By the rotation of the 1st axial region 32a, crank axle 32 is that center of rotation is rotated with the 2nd axial region 32b, and cam lever 31 rearward rotates and pushes locking external cam 12.Thus, as shown in figure 15, door 2a leaves set interval around peristome.
At this moment, the 1st axial region 32a (linking part) is less with the distance of axle 51 with respect to operating portion 5a with the distance of axle 51, and the operating physical force of operating portion 5a is exaggerated.In addition, with respect to the distance of the 1st axial region 32a (linking part) and the 2nd axial region 32b (support portion), the distance that is connected between the part on the locking external cam 12 of the 2nd axial region 32b and cam lever 31 is less.Thus, operating physical force is further amplified.Thereby, constitute force-increasing mechanism by handle 5 and rod unit 30, can be with lighter operating physical force pushing locking external cam 12.
In addition, because operating portion 5a and the 1st axial region 32a are configured in same side with respect to axle 51, so handle 5 is overlooked the overlay configuration of looking with rod unit 30.Thus, rod unit 30 is arranged in the width of left and right directions of handle 5.Thereby, even under the situation that the size of handle 5 is restricted, also the distance of operating portion 5a and axle 51 can be obtained long and obtain the bigger door open/close machine of magnifying power of small-sized and operating physical force.Under the situation in the space of the lower end that a 2a is arranged, also can make rod unit 30 expose and dispose from the width of handle 5.
In addition, because axle 51 and cam lever 30 are configured in opposition side with respect to the 1st axial region 32a, thus can be in the width of the left and right directions that rod unit 30 is located at handle 5, and shorten the distance of axle the 51 and the 1st axial region 32a.Thereby, operating physical force can be amplified biglyyer.
In addition, also can the distance that be connected to the part on the locking external cam 12 of the 2nd axial region 32b and cam lever 31 be formed about equally or slightly longways with respect to the distance of the 1st axial region 32a and the 2nd axial region 32b.If like this, then can not obtain the amplification effect of the operating physical force of rod unit 30.But, the distance of operating portion 5a and axle 51 can be obtained the bigger door open/close machine of magnifying power that obtains small-sized and operating physical force than length.
In addition, because handle 5 is different with the center of rotation of rod unit 30, fit loosely among the slotted hole 53a so link their the 1st axial region 32a.Also the 1st axial region 32a can be rotated and be fixed on freely on the handle 5 and the 2nd axial region 32b is fitted loosely on the 2a.Under the situation in that the 2nd axial region 32b is fixed with the 1st axial region 32a loose fit, can make the pushing position of cam lever 31 be necessarily pushing stably.
Figure 16 is the vertical view of configuration of the handle 5 in the expression cross section different with Figure 15.The fastener 58b that the rib 52c of handle 5 is connected to a cap 58 goes up and the restriction slewing area.Figure 17 represents that Figure 16's wants portion's details drawing.By the rotation of handle 5, the 1st axial region 32a of crank axle 32 moves to the front surface side of the 58a of hole portion.When rib 52c and fastener 58b butt, between the end of the nearside of the 1st axial region 32a and the 58a of hole portion, form gap d.
If the further 5a of pull operation portion, handle 5 strains then, crank axle 32 rotates, and shown in single-point line D, the 1st axial region 31a is connected on the end of the 58b of hole portion, limits the slewing area of handle 5.The butt of the butt of rib 52c and fastener 58b and the 1st axial region 31a and the 58b of hole portion both can be provided with the time difference and also can be made as simultaneously.
The cutaway view of Figure 18 indication window 58a of portion.The rib 58c that all causes of the 58a of hole portion are extended downwards constitutes, and at the nearside of the 58a of hole portion, is provided with the buffer unit 59 of rubber or sponge etc. on rib 58c.The impulsive sound that the collision of the 1st axial region 32a by buffer unit 59 being set, can relaxing the crank axle 32 that is made of metal brings.In addition, owing to do not make buffer unit 59 outstanding from the surface of recess 2b, and be located at the private side that depends on door 2a than the surface of recess 2b, so prevented that handle 5 from can make handle 5 successfully rotate with the interference of buffer unit 59.
And, by further pull handle 5, keeping the 1st axial region 31a and be connected to state on the end of the 58b of hole portion, door 2a rotates and opens.
Figure 19～Figure 22 is the vertical view of the action of the cam mechanism of expression when door 2a opened.In Figure 19, under the closed condition of door 2a, about cam mechanism be that the 1st card stop bit that joint pin 11 is configured on the end of the 1st grooved cam 24 is put.The 1st grooved cam 24 is owing to tilt to the center side of door 2a more more towards the rear, the coming off of causing so can prevent to spur the both sides of a 2a.
If the operating portion 5a of the handle 5 in the left side of pulling door 2a, then as above-mentioned shown in Figure 15, by the locking external cam 12 in cam lever 31 pushing left sides, a door 2a leaves from main part 6.Figure 20 represents the state of this moment.The cam mechanism in left side is relatively guided joint pin 11 by the 1st grooved cam 24, and locking external cam 12 is slided with slip external cam 22.The cam mechanism on right side is relatively guided joint pin 11 by the 2nd grooved cam 25.Thus, while door 2a rotates to the left-hand slip mobile.
If further pull handle 5, then cam lever 31 leaves from the locking external cam 12 in left side.Figure 21 represents the state of this moment.The cam mechanism in left side and above-mentioned same, joint pin 11 is relatively guided by the 1st grooved cam 24, and locking external cam 12 is slided with slip external cam 22.The cam mechanism on right side is configured in joint pin 11 on the end of the 2nd grooved cam 25, and protuberance 23 begins to slide with rib 13.Thus, the relative slip of joint pin 11 is rotated supported freely by locking.
If further pull handle 5, then as shown in figure 22, the cam mechanism in left side will engage releasing.The cam mechanism on right side ends position protuberance 23 at the 2nd card and slides into rib 13, and slip external cam 22 is slided and guided locking external cam 12.And the cam mechanism on right side is kept the 2nd card stop bit and is put and door 2a is opened.
Two door 2a that open are accompanied by when opening to the slip in the outside of opening side and move about above-mentioned.Because operating portion 5a is with respect to the center side that is configured in a 2a as the axle 51 of the turning cylinder of handle 5, so the operating physical force of operating portion 5a is towards the movement outside of opening side.Thereby, can easily make a 2a slip move and obtain the better door open/close machine of operability.
According to present embodiment, with respect to axle 51 as the turning cylinder of handle 5, comprising crank axle 32 with operating portion 5a same side, crank axle 32 has the 1st axial region 32a that fits loosely in the handle 5 and forms abreast with the 1st axial region 32a and be supported on the 2nd axial region 32b on the 2a, so handle 5 can be disposed with crank axle 32 with overlapping and door open/close machine is made small-sized, and amplify by the operating physical force of crank axle 32, can door be opened by lighter operating physical force with the 5a of pull operation portion.
In addition, be construed as limiting the 1st retainer of the rotation of handle 5 by the 58a of hole portion of the 1st axial region 32a butt.Thus, because the 1st axial region 32a is made of metal,, can limit the rotation of handle 5 cheaply so do not need to strengthen.In addition, because operating portion 5a and the 1st axial region 32a are configured in same side with respect to axle 51, so operating portion 5a and the 1st axial region 32a are approaching.Therefore, when the end face butt of the 1st axial region 32a and the 58a of hole portion, the power that is applied on the 58a of hole portion diminishes, and because the torque that is applied on the handle 5 is a fulcrum with the 1st axial region 32a, so diminish.Thereby, can prevent the damage of 58a of hole portion and handle 5.
In addition, be construed as limiting the 2nd retainer of the rotation of handle by fastener 58b with respect to the rib 52c butt on the end that is located at handle 5 of axle 51 and operating portion 5a opposition side.Thus, the rotation of logical via portion 58a (the 1st retainer) and fastener 58b (the 2nd retainer) restriction handle 5.Therefore, load is distributed on 58a of hole portion and the fastener 58b, can prevent the damage of the 58a of hole portion, fastener 58b and handle 5.
In addition owing on the wall of the recess 2b that takes in handle 5, form the hole 58a of portion, so handle 5 and the 58a of hole portion crank axle 32 axially near and dispose.If the 1st retainer of the rotation of restriction handle 5 axially leaves along crank axle 32,, also can apply bigger load to handle 5 because of toppling over of crank axle 32 even then rotate by the restriction of the 1st retainer.Thereby, can reduce the load that toppling over of crank axle 32 brings.
In addition, rotate the degree also can not interfere, be connected on the wall of inner surface side of the 1st spatial portion 56b of shaft-cup 56 rotation that comes limiting door 2a by the 1st axial region 32a even also the 58a of hole portion can be formed significantly the 1st axial region 32a.Thus, the wall of inner surface side that also can be by the 1st spatial portion 56b constitutes the 1st retainer.In addition, as shown in figure 23, if the jut 56h that is made of rib with the 1st axial region 32a butt is set on the inwall of the 1st spatial portion 56b, then jut 56h becomes the 1st retainer.Thus, can increase the thickness of the 1st retainer and improve intensity.
Then, Figure 24 (a), Figure 24 (b) are that the positive view that expression is inserted the details of the state in the shaft-cup 56 that leads to the 2nd embodiment with crank axle 32 reaches upward cutaway view.In addition, Figure 25 (a), Figure 25 (b) are the vertical view and the positive views of expression shaft-cup 56.For convenience of explanation, for giving identical label with the same part of the 1st embodiment of above-mentioned Fig. 1～shown in Figure 23.The structure of the shaft-cup 56 of present embodiment is different with the 1st embodiment.Other parts are identical with the 1st embodiment.
Shaft-cup 56 forms along the crank-like of crank axle 32, and the 1st spatial portion 56b that is equipped with the top of the 1st axial region 32a is communicated with the 2nd spatial portion 56c of the below that is equipped with the 2nd axial region 32b.The 1st spatial portion 56b form overlook roughly fan-shaped so that the 1st axial region 32b and the continuous 32d of portion can rotate.
The width W 1 of the 1st spatial portion 56b forms widelyer than the length of the continuous 32d of portion of crank axle 32.Thus, in the present embodiment, insert than the open end of bend 32c above the 1st spatial portion 56b that the continuous 32d of portion is short.And bend 32c slides on the bottom surface of the 1st spatial portion 56b and is configured among the 2nd spatial portion 56c, and the 32d of portion is inserted among the 1st spatial portion 56b continuously.Therefore, also the width W 2 of the 2nd spatial portion 56c can be formed wideer and narrower than the length of the continuous 32d of portion than the length of bend 32c.
In addition, the continuous 32d of portion than the short situation of bend 32c under, the open end of the continuous 32d of portion below the 2nd spatial portion 56c can be inserted slip on the upper surface of the 2nd spatial portion 56c and being configured among the 1st spatial portion 56b.In the case,, form the 1st, the 2nd spatial portion 56b, the width W 1 of 56c, W2 wide just more passable than the length of the continuous 32d of portion so need only because bend 32c will connect in the shaft-cup 56, also can be narrower than the length of bend 32c.
The end of the 1st axial region 32a side of the 2nd spatial portion 56c is made of the barrel surface of cross section semicircle shape, is formed with the fitting portion 56a of being equipped with a plurality of ribs 56f with radial on this barrel surface.Chimeric the 2nd axial region 32b of fitting portion 56a, a side of the width of the 2nd spatial portion 56c is open and support roughly half cycle.
