Description of the Related Art Conventionally, a vending machine for canned juice or the like (hereinafter referred to as "vending machine") is provided with a lid for preventing rain and dust from entering the product outlet. The upper end of the lid is pivotally supported by the opening of the vending machine, and is rotatable up and down around the upper end. To remove the product that has fallen into the product outlet from the product case inside the vending machine, remove the product while rotating it to lift the lower end of the lid, opening the lid and supporting it with your hand so that it does not fall. Remove the support and close the lid. Further, in order to prevent the lower end of the lid that drops when closing the lid from violently colliding with the end of the product take-out port, a lid having a multi-plate damper or a damper using oil shear resistance has been proposed. I have. Such a damper is a bidirectional damper that generates a high torque irrespective of the opening and closing direction of the lid, and does not fall suddenly at least when the lid is closed.

があった。However, in the case of a lid to which the above-mentioned damper is not attached, when taking out the product, the lid must be held down with one hand so as not to fall. Also, if the user tries to take out the product while supporting the lid with only one hand, there is a problem that the sleeve of the arm is stained by dust or rainwater attached to the lower end of the lid. Further, when the lid is closed, the lower end of the lid that has fallen sharply collides vigorously with the end of the product take-out port, and thus there is a problem that a loud collision sound is generated.

Although the inconvenience is solved, there are the following problems. First, when the lid is opened, a high torque is generated, so that the opening becomes heavy. Also,
Since the magnitude of the generated torque cannot be changed when the lid is closed, if the generated torque is too large, the closing lid stops halfway and cannot be closed reliably. As a result, dust and rainwater get into the product outlet, and the effect of the lid is not sufficiently exhibited. On the other hand, if the generated torque is too small, the lid closes quickly and it is not possible to secure sufficient time for taking out the product.

The rotating member 3 is provided with a ridge 31 protruding from the outer peripheral surface along the axial direction. The ridge 31 is covered with a valve element 4 which rotates while being engaged with the rotation of the rotating member 3. A notch p is formed in the middle of the top of the ridge 31 in the axial direction. The valve element 4 is a cover valve having a substantially U-shaped cross section. The valve element 4 is covered with play in the rotation direction on the upper part of the ridge 31. It rotates with a small gap between them. A notch q is formed in one of the left and right hanging walls 41 and 42 of the valve body 4 along the axial direction, and a notch is formed in the other hanging wall 42. Not formed. When the rotating member 3 rotates in the direction of the hanging wall 41, the notch q
The bypass flow path for the viscous fluid 5 is secured, and the generated torque is reduced. On the other hand, when rotating in the direction of the hanging wall 42, there is no notch q on this side, so the notches p and q

うにするのが好ましい。In the central portion of the outer peripheral surface of the rotating member 3, the starting area S in FIG.
Is formed in the circumferential direction. This first
The groove r is formed so that the width in the axial direction is constant and the depth gradually increases from the start end region S to the end region E. A convex portion 9 is provided on the inner surface of the cylindrical casing 2 along the axial direction. When the rotating member 3 rotates, the upper surface of the convex portion 9 and the first groove face each other. Through the outer peripheral surface of the rotating member 3. The gap formed by the upper surface and the first groove r forms a bypass flow path for the viscous fluid 5, and the generated torque can be reduced as the cross-sectional area of the first groove r in the axial direction is larger. That is, the rotating member 3
When the starting end region S faces the upper surface of the convex portion 9 in the rotation stroke of, a high torque is generated because the cross-sectional area of the bypass passage in the axial direction is small. On the other hand, when the terminal region E faces the upper surface of the projection 9 during the rotation stroke, the generated torque can be reduced to almost zero because the axial cross-sectional area of the bypass passage is large. The shape and position of the first groove r are not limited to those shown in the drawings. That is, when the terminal region E faces the upper surface of the convex portion 9, the generated torque becomes substantially zero, and there is a region where a high torque is generated from the start region S to the terminal region E. For example, the groove width may be gradually increased from the start end region S to the end region E while keeping the groove depth constant. When the weight of the lid is heavy, the lid easily falls due to its own weight. Therefore, a groove having a large sectional area is formed only in the terminal region E, and no groove is formed in other portions of the outer peripheral surface of the rotating member 3. You may. In order to take out the product, it is easier to take out the product if the cover C is sufficiently opened. Therefore, it is preferable to provide a high torque region in a predetermined region from the starting end region S to the intermediate region M.

It consists of adjusting means. The second adjusting means is such that the valve element 4 covered on the ridge 31 as shown in FIG.
It may be configured to rotate integrally with one. FIG. 5 (a)
The adjusting means shown in (1) comprises a valve element 4 having a ridge 31 having a substantially circular cross section, a flat portion 43 for blocking a bypass flow path of the viscous fluid 5, and an upper surface 44 shaped to form a bypass flow path. The adjusting means shown in FIG. 5B includes a ridge 31 having a substantially rectangular cross section and a flat portion 4 for blocking the bypass flow path of the viscous fluid 5.

This is shown in FIG. The rotating member 3 has the top end of the ridge 31 directed to the upper right in the figure, and the ridge 31 has its left end surface in contact with the hanging wall 41 of the valve body 4 in the figure. The starting region S of the first groove r formed on the outer peripheral surface of the rotating member 3 is located so as to face the upper surface of the convex portion 9. From this state, the lid C falls naturally by its own weight, but first the rotating member 3 slightly rotates clockwise in the figure until the right end face of the ridge 31 contacts the hanging wall 42 of the valve body 4.

Since the notch q is not formed in the hanging wall 42 located on the first side, the chamber 21 has a small gap formed between the upper surface of the valve body 4 and the inner peripheral surface of the cylindrical casing 2. A small gap formed between the upper surface of the convex portion 9 and the outer peripheral surface of the rotating member 3 is merely secured as a flow path for the viscous fluid 5. Therefore, high torque is generated over the entire rotation stroke during this period. On the other hand, the first adjusting means generates torque as follows. First, FIG.
4 (b), the cross-sectional area of the first groove r passing through the upper surface of the convex portion 9 while facing the upper surface of the convex portion 9 is small, so that the bypass flow path is narrow and a high torque is generated. . In the rotation stroke from FIG. 4B to FIG. 4C, the cross-sectional area of the first groove r passing through the upper surface of the projection 9 gradually increases, and the bypass flow passage also gradually widens. It gradually decreases, and becomes almost zero when the terminal region E reaches the position facing the upper surface of the projection 9.

Until (b), the torque generated by the first adjusting means is gradually reduced, but the high torque is maintained, and
Since the torque generated by the adjusting means is always a high torque, the entire torque range is high. Therefore, in the rotation stroke during this time, the lid C falls slowly, and it is possible to secure a sufficient time to take out the product in the product takeout opening by hand, and to prevent the cover C from hitting the arm during the taking out. On the other hand, from FIG. 4B to FIG.
Although the torque generated by the second adjusting means is still a high torque over the entire rotation stroke, the torque generated by the first adjusting means is greatly reduced. At the time of facing the upper surface of No. 9, the torque becomes almost zero. Therefore, after the product is taken out, the lid C gradually increases its falling speed through the horizontal state, and the torque becomes almost zero near the stop position. As a result, the lid comes into contact with the lower end of the product take-out port in a substantially vertical state and stops at this position, so that the lid can be completely closed. Note that since the generated torque sharply decreases in the end region E of the rotation stroke, the lid C does not suddenly collide with the end of the product outlet and does not generate an impact sound.

As described above, the cross-sectional state of the shock absorber 1 when the lid C is completely closed is shown in FIG. When the lid C is lifted and opened from this state, first, the rotating member 3 slightly rotates counterclockwise in the figure until the right end face of the ridge 31 comes into contact with the hanging wall 41 of the valve body 4. When the rotation is further continued, the right end surface of the ridge 31 is suspended from the hanging wall 41.
As the valve element 4 is rotated while being pressed in FIG.
After the state of (d), the rotation stops in the state of FIG. In the state shown in FIG. 4A, the lid C is in the fully opened state and is inclined from the vertical direction to the outside of the vending machine A. Drop naturally and close.

で、発生トルクは非常に小さいものとなるIn the first adjusting means, a torque is generated as follows in a process reverse to the above-mentioned closing operation. First, in the rotation stroke from FIG. 4 (c) to FIG. 4 (d), the cross-sectional area of the first groove r passing through this surface while facing the upper surface of the projection 9 gradually decreases, and the generated torque is reduced. Gradually increases. From FIG. 4D to FIG. 4A, a high torque is generated because the cross-sectional area of the first groove r passing through the upper surface of the projection 9 is extremely small. Regarding the second adjusting means, since the notch q is formed in the hanging wall 41 located on the pressurizing chamber 22 side, over the entire rotation stroke from FIG. 4C to FIG. A bypass passage leading from the notch q to the notch p is secured.
Therefore, since the viscous fluid 5 can flow from the pressurizing chamber 22 to the depressurizing chamber 21 during the entire rotation stroke during this period, the generated torque is very small.

蓋Ｃを開けるくことができる。When the first and second adjusting means operate simultaneously during the rotation stroke, the torque generated by the first means gradually increases, but the torque generated by the second means decreases throughout the rotation stroke. In order to maintain the torque, the entire rotation stroke is in the low torque region due to the effect of the low torque by the second means. Therefore, there is almost no resistance in the rotation stroke during this time,
The lid C can be opened.

When the lid is closed, as shown by (1) in the figure, a high torque is generated from the state of FIG. 4 (a) to the state of FIG. 4 (b), and the generated torque gradually decreases from this state, as shown in FIG. Before reaching the state of c), the torque rapidly decreases and the torque becomes almost zero. On the other hand, when the lid is opened, as shown by (2) in the figure, the rotation stroke from the state of FIG. 4 (c) through the state of FIG. 4 (d) to the state of FIG. 4 (a) Overall, the generated torque is low. In addition,
The magnitude of the generated torque on the vertical axis in FIG. 10 is an arbitrary unit.

る。As described above, in the shock absorber 1 according to this configuration example, when the lid rotates in the closing direction, the braking force acts on the rotation of the lid in the high-torque generating region and the lid closes slowly. Since the torque becomes almost zero, the lid can be completely closed without fail. Further, when the lid is opened, the torque is low, so that the lid can be easily opened.

And third adjusting means comprising a second groove s. The second groove has a reduced cross-sectional area in the axial direction so as to generate a high torque in the start end region, and a larger cross-sectional area in the end region of the rotation stroke so that the generated torque is almost zero. ing.

１と同様に作用する。The third configuration example shown in FIG. 7 is a modification of the first configuration example, in which the second adjusting means composed of the ridge 31 and the valve element 4 is modified. As shown in FIG. 9, the second adjusting means of this example includes a wavy shape composed of two ridges 33 and 34 protruding from the outer peripheral surface of the rotating member 3 and a concave portion 35 formed between these ridges. And a rod-shaped valve body 47 whose lower half is fitted into the recess. A notch t is formed in the middle of the top of one of the ridges 33.
In FIG. 7, when the rotating member 3 rotates clockwise in the figure, the viscous fluid 5 flowing into the recess 35 from the notch t pushes up the valve body 47, so that the viscous fluid 5 moves between the ridge 34 and the inner surface of the casing 2. closing the gap formed, for generating a high torque for blocking the bypass flow passage of the viscous fluid 5. On the other hand, when the rotating member 3 rotates counterclockwise in the figure, even if the valve element 47 is pushed up by the viscous fluid 5 flowing from the ridge 34 side,
Since the notch t secures the bypass flow path for the viscous fluid, the generated torque is small. Note that, in this example, the protrusion 9
The first adjusting means composed of the first groove r operates in the same manner as in the first configuration example.

It was done. This adjusting means generates a high torque when the rotating member 3 rotates clockwise in the drawing, and generates a small torque when the rotating member 3 rotates counterclockwise, as in the third configuration example. Therefore, the second adjusting means consisting of the ridge 31 and the valve element 4 may not be provided, and the ridge 31 whose upper surface is opposed to the inner peripheral surface of the casing 2 with a small gap is sufficient. In the fourth configuration example, the ridge 34 or the valve element 4
The same effect as the first adjusting means of the first configuration example can be obtained by the adjusting means composed of the groove 7 formed on the inner peripheral surface of the casing 2 and the inner circumferential surface of the casing 2.

For this reason, it is possible to take out the product at the product take-out opening with one hand while falling slowly, preventing the lid from hitting the arm while taking out, for example, soiling the sleeve part with dust or rainwater it can. Further, since the torque is set to be substantially zero at least at the end region of the rotation stroke, the cover can be completely closed without applying a braking force to the cover in this region.
