Moreover, the recessed part 36 is formed in the back side of the engaging part 34 of the latch main body 30, and the cam 38 which made the substantially heart shape from the front side in the recessed part 36 is formed. Formed. The lock lever 40 which is pivotably attached to the inner side of the latch main body 30 traces the outer periphery of this cam 38. As shown in FIG.

When the latch body 30 protruding from the opening 28 is pressed in a direction that resists the holding force of the spring 32 and stored in the case 26, the lock lever 40 is moved around the outside of the cam 38. Is locked to the engaging portion 42, and the locked state between the click portion 22 and the engaged portion 34 is maintained (see FIG. 2 (A)).

In this state, when the latch main body 30 is pressed in the direction that resists the holding force of the spring 32, the locking state of the lock lever 40 is released, and the lock lever 40 moves the outer circumference of the cam 38. It traces and catches on the latching part 44, and the locked state of the click part 22 and the engaged part 34 is canceled (refer FIG. 2 (B)).

According to the above configuration, the free end side central portion of the lid 14 is pressed to lock the click portion 22 and the engaged portion 34 to close the lid 14, and the lid body ( When the free end side central part of the cover body 14 is pressed again in the closed state 14, the locked state of the click part 22 and the engaging part 34 is released, and the cover body 14 is opened.

And as shown in FIG. 1 and FIG. 5, the arc-shaped guide part 43 is formed in the both sides of the main body 12. As shown in FIG. The guide portion 43 is formed on the side, and at the edge of the guide hole 45 through which the shaft 48 (shaft on one side) and the shaft 50 (shaft on the other side) can pass, The guide ribs 46 are formed to stand outward, and the shafts 48 and 50 are movable along the guide portion 43.

43 A of branch parts are formed in the guide part 43, and this branch part 43A has the branch hole 45A and the guide rib 46 formed in circular arc shape from the guide hole 45. As shown in FIG. It consists of the branch rib 46A formed in succession, and the shaft 48 is movable to the branch part 43A in the state in which the shaft 50 reached the edge part of the guide part 43. As shown in FIG.

On the other hand, one end of the opening spring 56 is attached to the front end of the shaft 48, and the other end of the opening spring 56 is fixed to the attachment piece 10A protruding from the outer surface of the main body 12. It is supported in the direction which opens the cover body 14 through the shaft 48. As shown in FIG.

As a result, as shown in Figs. 3 and 4, when the lid 14 is closed, the lid 14 is pressed to resist the holding force of the spring 56 for opening to the lid 14. With the load applied, the shafts 48 and 50 are moved along the guide portion 43 to guide the lid 14 in the closing direction, and the shaft 50 abuts against the edge portion of the guide portion 43. The click portion 22 of the lid 14 is close to the tip of the latch body 30.

In this state, the lid 14 is repeatedly pressed to accommodate the latch body 30 in the case 26 as described above, so that the lock lever 40 is caught by the locking portion 42. At this time, the shaft 48 is moved along the cutout portion 54A around the shaft 50 to move along the branch portion 43A to close the lid 14.

In the state in which the lid 14 is closed, when the free end side center portion of the lid 14 is pressed to release the locked state of the click portion 22 and the engaged portion 34, the opening spring 56 The lid 4 is automatically opened by the holding force.

At this time, the shaft 48 moves along the cutout 54A around the shaft 50 to open the lid 14 at a predetermined angle (θ = 15 ° in this case), and then the shafts 48 and 50 are moved. The cover body 14 is completely opened while moving along the guide portion 43.

In this way, by changing the movement trajectory of the lid halfway, when the lid 14 is opened, the lid 14 can be accommodated on the back surface of the body 12 so that the lid 14 is obstructed. Is not going to be.

The small sector gear 64 serving as the third to-be-controlled gear can be fitted to the distal end of the shaft 48, and the upper side of the guide portion 43 moves together with the shaft 48.

This small sector gear 64 is fitted with a braking gear 62 of a known oil-enclosed rotary damper attached to a sector gear 54, which will be described later, so that the shaft 48 branches about the shaft 50. When moving along 43A to open the lid 14, the holding force of the opening spring 56 is braked by the engagement of the small sector gear 64 and the brake gear 62. FIG.

Thereby, while the shaft 48 moves in the branch 43A, i.e., until the lid 14 is started to open and the opening angle is 15 °, the lid 14 is opened slowly. Can be.

On the other hand, a fixed shaft 52 is erected at the arc center of the guide portion 43, and a sector gear 54 as a fourth brake gear is rotatably supported by the fixed shaft 52. As shown in FIG. The sector gear 54 is provided with a cutout portion 54A which can move the shaft 48 and a shaft support portion 54B for axially supporting the shaft 50.

As a result, when the front end of the shaft 48 passes through the cutout portion 54A, and the shaft 50 is fitted to the shaft support portion 54B, the sector gear 54 moves with the shaft 48 and 50 and the fixed shaft 54 moves. It becomes rotatable about 52.

Therefore, when the lid 14 is opened, the shafts 48 and 50 are moved along the guide portion 43 as the lid 14 moves, and the sector gear is centered around the fixed shaft 52. 54 is rotated.

The brake gear 60 of the well-sealed rotary damper fixed to the side face of the main body 10 is engaged with the sector gear 54. When the sector gear 54 rotates, the sector gear 54 and the sector gear 54 are rotated. The engaging force of the opening spring 56 is braked by the engagement of the brake gear 60. As a result, the lid 14 can be slowly opened while the shafts 48 and 50 move in the guide portion 43.

With the above configuration, when the lid 14 is opened, the small sector gear 64 and the brake gear 62 from the start until the opening angle of the lid 14 becomes 15 °. ), The holding force of the opening spring 56 is braked, and the gap between the sector gear 54 and the braking gear 60 is maintained while the cover body 14 is opened from the opening angle of 15 ° to the completion of opening. The holding force of the opening spring 56 is braked by the engagement.

Thereby, even if the cover body 14 whose movement trajectory changes on the way, the holding force of the opening spring 56 can be braked continuously from the opening start of the cover body 14 to the completion of opening. Thereby, high quality can be provided to the container holder 10. FIG. In addition, by forming the plurality of braking gears 60 and 62 in this way, the opening speed can be changed in accordance with the opening angle of the lid 14.

As shown in Fig. 6, a concave concave portion 58 is formed on the rear surface of the sector gear 54, so that the braking gear 62 of the oil-sealed rotary damper can be accommodated. The braking gear 62 has pedestals 68 protruding from both sides and is substantially equal to the length of the receiving recess 58 in the longitudinal direction.

The width of the recessed concave portion 58 is larger than that of the braking gear 62, so that the braking gear 62 is slidable within the accommodating recess 58. As shown in FIG. Moreover, from both ends of the storage recessed part 58, when the sector gear 54 is arrange | positioned, the temporary fixing piece 66 faces parallel with the bottom surface of the storage recessed part 58 so that it may face the small sector gear 64. As shown in FIG. It protrudes. The separation distance between the temporary fixing piece 66 and the bottom surface of the storage recess 58 is approximately equal to the thickness of the pedestal 68 formed on the braking gear 62.

As a result, as shown in FIG. 7, when the braking gear 62 is slid after storing the braking gear 62 in the housing recess 58, the axial movement of the sector gear 62 is restricted and temporarily fixed. Therefore, when the sector gear 54 is axially supported by the fixed shaft 52, the braking gear 62 is not separated from the sector gear 54.

In addition, when the sector gear 54 is axially supported by the fixed shaft 52, the brake gear 62 can be engaged with the small sector gear 64. As shown in FIG. By the engagement of the braking gear 62 and the small sector gear 64, the braking gear 62 is restricted from the slide movement so that the braking gear 62 does not fall into the state accommodated in the receiving recess 58.

In this way, by attaching the brake gear 62 to the sector gear 54, the space for attaching the component in the planar direction can be reduced. In addition, compared with the case where the braking gear 62 is fixed by a fixing screw or the like, the number of parts is small and the attachment is easy, thereby reducing the cost.

In addition, although the braking gear 62 was attached to the back surface of the sector gear 54 here, you may form and attach a receiving recessed part to the surface of the sector gear 54. As shown in FIG. Moreover, although the predetermined angle of the cover body 14 was set to 15 degrees, the angle differs according to the locking means. In addition, although the moving traces of the cover body 14 were made into two, it is not limited only to this, 3 or more may be sufficient.

In addition, since the holding force of the opening spring 56 can be braked continuously from the start of opening of the cover body to the completion of opening, it is not limited only to this form. For example, as shown in FIGS. 8 and 9, the braking gear 70 may be attached to the side surface of the main body 72.

In this case as well, in this case, when the lid 74 is opened, the small sector gear 76 and the brake gear 70 are engaged with each other during the opening of the lid 74 to a predetermined angle. The holding force of the opening spring 56 is braked and the holding force of the opening spring 56 is engaged by the engagement of the sector gear 78 and the braking gear 80 during the opening completion at a predetermined angle. Braking

In addition, although the movement trace of the lid | cover 74 is changed in the middle here, you may use the braking mechanism by this form also when a movement trace is not changed. In this case, the braking force for braking the holding force of the opening spring can be changed in accordance with the opening angle of the cover body.

For example, as shown in FIGS. 10 and 11, when the lid 84 is opened, the sector gear 82 is coupled with the brake gear 86 during the opening of the lid 84 to a predetermined angle. In this case, the sector gear 82 is engaged with the braking gear 86 and the braking gear 88 until the opening is completed at a predetermined angle.

As a result, the opening speed of the lid 84 can be slowed down from the start of the opening to the predetermined angle, from the opening to the completion of the opening. In this way, the opening speed can be changed in accordance with the opening angle of the lid.

In addition, the braking mechanism according to the present embodiment does not necessarily need to be used as a container holder as it may be provided with a lid for opening and closing the box. In addition, although a braking gear and a driven gear are used as a braking means, since the holding force of the holding means which hold | covers a cover body in the opening direction can be braked, it is not limited only to this.

Since this invention made the said structure, in the invention of Claim 1, an opening speed can be changed according to the opening angle of a cover body. In the invention as set forth in claim 2, the first and second braking gears are engaged with the first and second braking gears, whereby the braking force of the first and second braking gears is transmitted to the first and second braking gears. 1 Brake gears can brake the holding force of the holding means from the opening of the cover to the completion of opening, thereby slowly opening the cover.

In the invention according to Claims 3 and 4, even if the cover body in which the movement trajectory is changed on the way, the holding force of the holding means can be braked continuously from the opening of the cover body to the completion of opening. Further, by forming a plurality of braking means, the opening speed may be changed in accordance with the opening angle of the lid.

In the invention described in claim 5, the space for attaching the component in the planar direction can be reduced. In the invention according to claim 6, the third brake gear is not separated when the fourth brake gear is attached to the shaft on the other side. In addition, since the third brake gear meshes with the third driven gear, the third brake gear does not come out while being stored in the receiving recess, and compared with the case of fixing the third brake gear with a fixing screw or the like. The small number and easy attachment make it possible to reduce costs.

In the invention according to claim 7, since the holding force of the holding means for opening the lid can be braked from the opening of the lid to the completion of the lid, the sense of quality can be imparted to the holder.
