Is equipped.

As for the opening and closing mechanism of the cover 6, an arm 1 bent into a U-shape is provided on the upper side of the inner surface of the guide plate 4 of the main body 1.
Both ends of the base portion of the arm 5 are supported by a bracket 16 so as to be freely rotatable in the vertical direction, and both bent ends of the arm 15 are connected to connecting portions 17 provided on the left and right inner walls of the cover 6 via links 18. And a main body 1 and a locking member 19 integrally protruding from both ends of the base of the arm 15 to the rear side.
A pair of tension coil springs 20 are mounted between the arm 15 and the arm 15 to apply upward turning power to the arm 15. The opening / closing mechanism is provided with an electromagnetic lock device 21 for holding the cover 6 in a closed state. As shown in FIG. 2, a lock pin 22 protrudes from the upper edge of the back surface of the cover 6, while the upper edge of the guide plate 4 of the main body 1 has an inclined guide surface 25 at one end. A latch lever 24 provided with a fitting groove 26 in which the lock pin 22 fits is supported by a shaft 24 a, and a rotating power in the counterclockwise direction in FIG. The plunger 31 of the solenoid 30 similarly attached to the guide plate 4 is connected to the other end of the latch lever 24 via a link 32 while being held in the posture.

When the cover 6 is closed, the user holds the handle 33 provided on the front surface of the cover 6 and holds the tension coil spring 2.
The arm 15 is pulled down while rotating downwardly against the elasticity of zero. When the cover 6 reaches the lower position covering the opening 2 of the main body 1, the lock pin 22 contacts the guide surface 25 of the latch lever 24 and rotates it clockwise against the elasticity of the biasing spring 27. The fitting groove 26
When the latch lever 24 rotates and returns, and the lock pin 22 fits into the fitting groove 26, the cover 6 is locked in the closed state. When the cover 6 is opened, when the solenoid 30 is excited and the plunger 31 is retracted, the latch lever 24 rotates clockwise against the urging force of the urging spring 27 and the latch of the lock pin 22 is released. The arm 15 is pivoted upward by the restoring elasticity of the tension coil spring 20, and the cover 6 is moved upward to open the opening 2 of the main body 1.

The present invention is characterized in that braking is applied when the cover 6 is moved upward, and the braking mechanism will be described in detail with reference to FIGS. The outer surface of the cover 6 on the back side of the vertical groove 7 in which the guide roller 8 is fitted serves as a pressure contact surface 35 for braking. An L-shaped bracket 37 having a U-shaped cross section is provided at the upper end of the outer surface of the main body 1 at a position corresponding to the press-contact surface 35 of the guide plate 4. It protrudes above the recess 38 and is fixed by screws 39. An idle roller 40 is rotatably supported by a shaft 41 at an inwardly projecting end of the bracket 37.
On the side of the idle roller 40, a lever 42 whose inner end faces obliquely downward and whose outer end extends substantially horizontally is formed on the bracket 37 with its outwardly extending end. It is inserted through the escape groove 43 and is freely rotatably supported by the same shaft 41 as described above.

A rubber brake roller 44 made of urethane rubber and having a smaller diameter than the idle roller 40 is rotatably supported by a shaft 45 at the inwardly protruding end of the lever 42. A tension coil spring 47 is mounted between the outwardly extending end of the lever 42 and a pin 46 protruding from the rear surface of the bracket 37, and the lever 42 is turned counterclockwise in FIG. Power is energized,
As a result, the brake roller 44
And presses into the gap between the pressure contact surface 35 from below and comes into contact with them. Next, the operation of the first embodiment will be described.

When the lock is released from the closed state of the cover 6, the cover 6 pushes the brake roller 44 counterclockwise in FIG. 4 by the urging force of the built-in tension coil spring 20 as described above. Rotate and
While the idle roller 40 is trying to move up at a rapid speed while rotating clockwise, the brake roller 44 is brought into contact with the pressure contact surface 35 of the cover 6 with the upward movement of the cover 6.
The upward moving force acts due to the frictional force between the idle roller 40 and the pressure roller 35 and the gap between the idle roller 40 and the press contact surface 35, thereby receiving the resistance force and smoothly moving the cover 6 upward. Added. As a result, even when the cover 6 reaches the ascending limit position, it does not move up and down and stops smoothly.

On the other hand, when the cover 6 is moved downward to close the cover 6, the brake roller 44 receives a downward force, unlike the case where the brake roller 44 is moved upward from the press contact surface 35 of the cover 6, so that the brake roller 44 is disengaged. The brake roller 44 and the idle roller 40 rotate in the opposite directions to each other without giving any particular resistance, and the cover 6 can be moved down slightly. As described above, according to the first embodiment, when the cover 6 is moved upward, braking is applied and the cover 6 is stopped at a predetermined ascending limit position, and when the cover 6 is moved downward, the cover 6 can be closed with a small operating force without applying braking. it can. Further, since the braking mechanism is unitized and can be externally attached to the guide plate 4 of the main body 1, assembly and maintenance management can be easily performed.

The material of the brake roller 44 is preferably a rubber material having excellent resilience. The braking force can be controlled by adjusting the spring force of the extension coil spring 47. In addition, the brake roller 44 having a moderately large hole diameter with respect to the support shaft 41 is more likely to bite and the braking force is strengthened.
It has been confirmed that if the diameter of the brake roller 44 is made larger than that of the brake roller 44 as far as space permits, the operation is stabilized and the braking force is strengthened. <Second embodiment> Figs. 6 to 9 show a second embodiment. In the second embodiment, a mounting plate 6b is projected from the edge of the upper surface plate 6a of the cover 6 on the back side, and the movable rod 48 hanging down on the back side of the guide plate 4 of the main body 1 is attached to the mounting plate 6b. The upper end is fixed.

On the other hand, on the back surface of the guide plate 4, a brake cylinder 50 made of an oil-impregnated resin, through which the movable rod 48 is inserted with a clearance, is fixed vertically by a mounting member 51. Below the brake cylinder 50, one end of a lever 52 disposed on the back side of the movable rod 48 so as to intersect with the rod 48 is connected to a shaft 54 via a spacer 53 as shown in FIG. For free rotation. The movable rod 48 of the lever 52
Movable rod 48 on the opposite side of the shaft 54 with the
As shown in FIG. 9, the movable rod 4
A grooved roller 56 made of an oil-impregnated resin and having a circular arc-shaped groove 57 into which 8 is fitted is supported by a shaft 58.

An end of the lever 52 on the side opposite to the pivot support side;
Above this, a tension coil spring 60 is mounted between the pins 59 projecting from the guide plate 4, and the elastic force of the tension coil spring 60 causes the lever 52 to rotate clockwise about the shaft 54 in FIG. Biased, thereby providing grooved roller 5
6 is pressed against the movable rod 48. The brake mechanism according to the second embodiment has such a structure. When the cover 6 moves upward, the movable rod 48 is pulled up integrally therewith, and accordingly, the lever 52 is moved clockwise in FIG. A force in the direction of further pressing the grooved roller 56 against the movable rod 48 while rotating is applied. As a result, the movable rod 48 bends and assumes an oblique posture and is pressed against the inner peripheral surface of the brake cylinder 50, and braking is applied when the cover 6 moves upward due to frictional resistance therebetween.

When the cover 6 is moved downward, the roller 56 is pressed down with the downward movement of the movable rod 48, and the lever 52 is rotated counterclockwise in FIG. 7 against the elasticity of the tension coil spring 60. Works, whereby the movable rod 48 can assume a straight posture concentric with the inside of the brake cylinder 50, so that the lowering operation of the cover 6 is lightened without receiving frictional resistance from the brake cylinder 50 in which the movable rod 48 is loosely fitted. Done. In the second embodiment, as in the first embodiment,
There is an advantage that the brake can be applied and stopped when the cover 6 is moved up, the down movement operation can be lightened, and the braking mechanism can be externally attached to the guide plate 4 and the cover 6 of the main body 1.

In the braking operation, since the roller pressure is transmitted to the rod 48 and applied to the brake cylinder 50, the durability is excellent without abrasion. Further, by changing the mounting position of the tension coil spring 60, the braking force can be easily adjusted. Third Embodiment FIGS. 10 to 12 show a third embodiment. In the third embodiment, similarly to the above-described second embodiment, the upper plate 6 of the cover 6 is provided.
The upper end of a movable rod 48 hanging down on the back side of the guide plate 4 of the main body 1 is fixed to a mounting plate 6b protruding from an edge on the back side of a. On the other hand, on the back side of the guide plate 4, one end of a lever 52 a disposed on the back side of the movable rod 48 so as to intersect the rod 48 is turned by a shaft 62 provided at a position close to the movable rod 48. Freely supported. On the same shaft 62, a grooved roller 56a made of an oil-impregnated resin and having a circular arc-shaped groove into which the movable rod 48 is fitted is supported. On the lever 52,
At a position opposite to the roller 56a with the movable rod 48 interposed therebetween, a grooved roller 56b made of the same oil-impregnated resin as a pair with the roller 56a is supported by the shaft 63 at a position offset from the roller 56a. Have been.

A tension coil spring 60a is mounted between the other end of the lever 52a and a pin 59a protruding from the guide plate 4 above the lever 52a. The clockwise rotating power of FIG.
52b embraces the movable rod 48.
The braking mechanism of the third embodiment has such a structure. When the cover 6 moves upward, the movable rod 48 is pulled up integrally with the cover 6. A force in the direction of biting into the movable rod 48 is applied to the grooved roller 56b while rotating the lever 52a in the clockwise direction in FIG. 11, so that the rollers 52a and 52b strongly embrace the movable rod 48, and the resistance therebetween causes resistance. When the cover 6 is moved upward, braking is applied. When the cover 6 is moved down, a force is exerted to push down the upper roller 56b and rotate the lever 52a in the counterclockwise direction in FIG.
a, 56b is open to cover 6 without receiving resistance.
Is performed lightly.

In the third embodiment as well, the cover 6 can be stopped by applying a brake when the cover 6 is moved up, the lowering operation can be lightened, and the braking mechanism can be externally attached to the guide plate 4 and the cover 6 of the main body 1. Has advantages. A unique advantage of the third embodiment is that the two grooved rollers 5 whose braking operation is a rotating object are performed.
Since the pressing is performed by the press-contact of 6a and 56b, the wear is small, and the number of parts is structurally small. Since the shaft of one grooved roller 56a is also used as the shaft 62 of the lever 52a, the size can be reduced. The braking force changes the spring force of the tension coil spring 60a,
The position can be easily adjusted by changing the mounting position, and a stronger braking force can be obtained as the distance between the rollers 56a and 56b in the direction sandwiching the movable rod 48 is narrower.

<Fourth Embodiment> FIGS. 13 to 15 show a fourth embodiment. In the fourth embodiment, similarly to the second and third embodiments, the main body 1 is attached to the mounting plate 6b protruding from the rear edge of the upper plate 6a of the cover 6.
The upper end of a movable rod 48 which is hung on the back side of the guide plate 4 is fixed. On the other hand, on the back surface of the guide plate 4, two thick brake plates 65a, 6 made of acetal resin or the like having excellent wear resistance and no lubricating properties are provided as brake members.
5b is provided. The brake plates 65a and 65b are each provided with a through hole 66 at a substantially central portion in the longitudinal direction thereof for tightly fitting and inserting the movable rod 48, and a mounting hole for inserting a bolt 67 at one end. 68 are correspondingly provided. A bolt 67 is attached to one of the brake plates 65a.
The screw hole 6 is provided at the end opposite to the position where the mounting hole 68 is formed.
9 are formed.

The two brake plates 65a and 65b are
A movable rod 48 is inserted through each insertion hole 66, and the movable rod 48 is vertically stacked, and is attached to a bracket 70 fixed to the guide plate 4 by a bolt 67 passed through both attachment holes 68 and a nut 71 screwed thereto. The braking mechanism of the fourth embodiment has such a structure. When the adjusting screw 73 is screwed into the screw hole 69 of one of the brake plates 65a and the tip of the adjusting screw 73 contacts the other brake plate 65b, the screw is further screwed. 14
As shown in FIG. 7, the ends of the brake plates 65a and 65b opposite to the mounting side are opened, and the axis of each insertion hole 66 is inclined obliquely with respect to the axis of the movable rod 48 inserted therethrough. As a result, when the cover 6 moves upward and the movable rod 48 moves upward integrally therewith, frictional resistance is generated between the cover 6 and the inner surface of the insertion hole 66 to apply braking to the upward movement of the cover 6.

As described above, in the fourth embodiment, the cover 6 can be stopped at a predetermined position by applying a braking force when the cover 6 is moved upward, and can also be mounted externally. In particular, since the structure is simple, it can be manufactured easily and inexpensively. The adjustment of the braking force can be easily performed by changing the screwing amount of the adjusting screw 73. Since the portion of the inner surface of the insertion hole 66 of each of the brake plates 65a and 65b that is rubbed by the movable rod 48 is always the same, there is a possibility that uneven wear may occur and the braking force may gradually decrease. By changing the side of the inner surface of the insertion hole 66 to be rubbed, the uneven wear can be prevented, and a long-term braking function can be expected.

Further, as shown in a modification shown in FIG. 15, through holes 74 of the same diameter which serve both as an insertion hole for the rod 48 and a mounting hole for the bolt 67 are formed in both brake plates 65c and 65d. The screw holes 75 for screwing the adjusting screws 73 may be formed symmetrically on both sides of the through holes 74 of the one brake plate 65c while being formed at the aligned position. With this configuration, both brake plates 65c, 65d
Can be used by reversing left and right in addition to the above-mentioned reversal, and can be surely handled by preventing uneven wear of the insertion hole of the movable rod 48. <Fifth Embodiment> Figs. 16 to 19 show a fifth embodiment. In the fifth embodiment,
By utilizing the braking principle of the third embodiment described above, the braking action is only effective when the cover 6 reaches near the upper limit position.

The upper end of a movable rod 48 hanging down on the back side of the guide plate 4 of the main body 1 is fixed to a mounting plate 6c protruding from the rear edge of the upper plate 6a of the cover 6. On the back side of the guide plate 4, one end of a lever 52 b disposed on the back side of the movable rod 48 so as to intersect the rod 48 is freely rotatable by a shaft 62 a provided at a position close to the movable rod 48. Supported by the coaxial 62
A grooved roller 56a is supported on
A pair of grooved rollers 56b is supported by a shaft 62b at a position on the opposite side of the movable rod 48, at a position deviated upward from the roller 56a.

The lower surface of the other end of the lever 52b is received by a stopper pin 77 protruding from the guide plate 4, so that the lever 52b is always kept in a horizontal posture orthogonal to the axial direction of the rod 48. At that time, the rollers 56 with both grooves
a and 56b are in a non-contact state with the movable rod 48 as shown in FIG. An operation rod 79 for braking operation is suspended from the mounting plate 6 c of the cover 6 on the side of the movable rod 48 via a tension coil spring 80. The lower end of the operating rod 79 is inserted into an insertion hole 82 formed in a lifted plate 81 bent at the end of the lever 52b supporting the rollers 56a and 56b opposite to the shaft support side. It is fitted. A collar 84 is attached to the lower end of the operation rod 79 so that the attachment position can be adjusted, and a compression coil spring 85 is fitted on the upper surface thereof.

The braking mechanism of the fifth embodiment has such a structure. When the cover 6 moves upward, the movable rod 48 and the operating rod 79 are pulled up integrally therewith. 56b is open and the movable rod 48 is not embraced, so no braking is applied. When the cover 6 moves up to the vicinity of the upper limit position, as shown in FIG. 19, the compression coil spring 85 at the lower end of the operating rod 79 hits the lower surface of the lifted plate 81 of the lever 52b and kicks up the lever 52. Rotate in the clockwise direction in FIG. As a result, the double-grooved roller 56
a and 56b are closed to embrace the movable rod 48, and braking is applied by frictional resistance therebetween.

Thereafter, while the compression coil spring 85 is further elastically contracted and the tension coil spring 80 at the upper end of the operation rod 79 is pulled, the movable rod 48 and the cover 6 are moved to the upper limit position while the braking force is applied. Move up to When the cover 6 is moved down, the operation rod 79 is initially set.
The cover 6 and the movable rod 48 move downward integrally while the upper and lower tension coil springs 80 and the compression coil springs 85 attached to the cover 6 are restored to their original shapes. Both springs 8
When 0 and 85 are restored to their original shapes, the operating rod 79 is similarly moved down, and the compression coil spring 85 escapes below the kicked-up plate 81 of the lever 52, so that the lever 52b is moved counterclockwise in FIG. 17 to return to the original horizontal position as shown in FIG.
When the space between a and 56b is completely opened, the lowering operation is performed lightly without any resistance thereafter.

In the fifth embodiment, in particular, the braking is applied only when the cover 6 is moved up to the vicinity of the ascending limit position. Can be stationary. Also,
The strength of the braking force and the height limit position, that is, the height of the opening,
It can be arbitrarily selected according to the mounting position of the collar 84 and the length and strength of the upper and lower springs 80 and 85 mounted on the operation rod 79. The present invention is not limited to the dishwasher shown in each of the above embodiments, but can be widely applied to door devices of other devices having the same structure.
