Description

  The present invention relates to an opening / closing mechanism for an opening / closing member, and more particularly to an opening / closing mechanism for an opening / closing member capable of mounting a small gas spring in a narrow space and stopping the opening / closing member at a position where the opening / closing member is largely opened / closed.

Conventionally, in order to perform maintenance of various devices inside a main body device such as an automobile or an ATM (automated teller [telling] machine), the bonnet or front panel of the opening / closing member that is normally closed is fully opened. At this time, a gas spring is used as a member for maintaining the fully opened opening / closing member in the fully opened position. (For example, see Patent Documents 1 and 2.)
2 and 3, when the hood (door, engine ford) is fully opened, the lower end of the gas spring is formed below the locking groove (11). The gas spring is prevented from coming off from the locking groove (11).

  Further, in the technique described in Patent Document 2, when operating an internal unit or parts during ATM maintenance / operation / in-factory manufacturing test, the open panel is opened from the front to the top. It is described that a small gas spring can be mounted.

  FIG. 10 is a perspective view schematically showing a general shape of a conventional ATM. As shown in FIG. 10, the ATM 1 includes an open / close panel 4 integrated with the display unit 3 in front of the upper part of the main body cabinet 2.

  A card reading unit 6 having a card insertion slot 5 and a cash receipt / payment unit 8 having a cash insertion / payout port 7 are arranged below the opening / closing panel 4 of the main body cabinet 2 and below.

  FIGS. 11A and 11B are diagrams showing an example in which a gas spring is used to open and close the opening / closing panel 4 of the ATM 1 as described above. 11 (a) and 11 (b), the lower end portion of the gas spring 9 (9a, 9b) is rotatably supported by the support portion 11 on the inner side wall of the main body cabinet 2, and the upper end portion is a holding plate member of the open / close panel 4. 12 is rotatably held.

  FIG. 11A shows an example in which a relatively large gas spring is used as the gas spring 9a. The entire gas spring is large, the piston 13a is elongated, and the open / close panel 4 is fully opened. be able to. On the other hand, as shown in FIG. 11 (b), in the case of a small gas spring 9b, since the extension of the piston 13b is short, it does not open greatly even when the open / close panel 4 is fully opened.

  In general, in order to obtain a sufficient reaction force that supports the weight of the opening member by the gas spring and a sufficient opening angle of the opening and closing member, variation in the reaction force of the gas spring itself, variation due to temperature change, reaction force decrease due to secular change, etc. Therefore, it is difficult to set the initial reaction force against the gas spring.

  When the reaction force of the gas spring decreases, the fully opened opening / closing member cannot be held, and the opening / closing member falls naturally. Since the reaction force once set for the gas spring cannot be adjusted, the gas spring with a reduced reaction force must be replaced.

  By the way, in the technique described in Patent Document 1, when the fully opened bonnet is closed, the bonnet is once lifted with one hand so that the lower end of the gas spring is lifted from the recess at the lower part of the locking groove, and the other hand is used. It has a structure that requires the trouble of closing the bonnet while pushing the gas spring inward and removing it from the locking groove.

  In addition, if the main unit is expensive like an automobile, a gas spring can be specially ordered according to the size and weight of the bonnet, but there are many restrictions on the size of the main unit and the configuration of the internal unit, such as ATM. So there are restrictions on the options for gas springs.

  For example, it is necessary to increase the opening angle of the open / close panel during maintenance work or the like. However, if there is no space to attach a large gas spring that can provide the reaction force necessary to support the weight of the open / close panel, a small gas spring must be attached, and the opening angle becomes narrower.

In addition, when a large gas spring is forcibly adopted in favor of increasing the opening angle of the open / close panel, the size of the internal mounting unit or the like is restricted.
In view of the above-described conventional situation, an object of the present invention is to provide an opening / closing mechanism for an opening / closing member capable of mounting a small gas spring in a narrow space and stopping the opening / closing member at a position where the opening / closing member is largely opened / closed.

  In order to solve the above-described problems, an opening / closing mechanism for an opening / closing member according to the present invention is provided inside the vicinity of the opening in a housing having an opening, and at least a rotating force that generates a rotational force at a lower portion of the gas spring.

And a gas spring that is held and held at the upper holding portion by the upper holding portion.

  In the opening / closing mechanism of the opening / closing member, for example, the gas spring slidably engages the upper end portion with the groove hole of the upper holding portion, and the upper end portion is The first holding point is locked to the second holding point when the opening / closing member is opened, and the lower holding portion is formed by the cooperation of the biasing member and the rotating member. When the opening / closing member is opened, the gas spring is biased in the outward direction of the opening so as to move the upper end of the gas spring from the first holding point of the slot to the second holding point. Configured to be.

  In the opening / closing mechanism of the opening / closing member, for example, the slot in which the upper edge of the upper holding portion forms an arc shape is such that the upper edge portion of the first holding point is at the time of closing of the opening / closing member. It is positioned at the uppermost position than the other upper edge portions, and when the opening / closing member is opened, the upper edge portion of the second holding point is positioned at the uppermost position than the other upper edge portions. Composed.

  In the opening / closing mechanism of the opening / closing member, for example, when the upper end portion is locked to the first holding point and when the upper end portion is locked to the second holding point, A straight line connecting the upper end portion and the lower end portion is configured to be inclined toward the inside of the casing with the lower end portion as a base point.

  In the opening / closing mechanism of the opening / closing member, for example, the urging member has a urging force, and one end is connected to a urging member holding portion fixed to a predetermined position inside the housing. An end is connected to the rotation end of the rotation member, and the rotation member is supported by a rotation fulcrum fixed inside the housing at a position lower than the biasing member holding portion inside the housing. The pivot fulcrum and lower support hole are pivotably held by the portion, and has a notch portion above the pivot fulcrum and lower support hole, and the gas spring is provided at the lower end of the pivot member. A held hole that is rotatably held by the rotation fulcrum and lower support hole, and is formed above the held hole and protrudes in a direction perpendicular to the axis of the gas spring, and the notch of the rotation member. And a plate piece member fitted to the portion, and added to the lower end portion from the rotating member. The rotational force, the upper portion is moved from said first holding point on the second holding points, as configured.

  In the opening / closing mechanism of the opening / closing member, for example, the turning member is urged to turn upward by the urging member with the turning fulcrum / lower support hole as a fulcrum, and the notch The end portion on the rotating end side of the gas spring presses and urges the end portion on the rotating end side of the plate piece member of the gas spring fitted in the notch, and the force of the pressing force And a distance between the held hole of the gas spring and the protruding portion of the plate piece member generates a rotational force in the formed portion of the held hole, and when the opening / closing member is fully opened, the rotational force The upper end portion of the gas spring is forcibly moved from the first holding point of the slot of the upper holding portion to the second holding point via the main body of the gas spring. Is done.

  In the opening / closing mechanism of the opening / closing member, for example, the upper holding portion includes an adjustment groove formed along the arc of the upper edge of the groove above the groove, a horizontal portion, and a vertical portion. And is engaged with the adjusting groove hole by the lateral portion, and a fixing position with respect to the adjusting groove hole is set at an arbitrary position along the adjusting groove hole by the fixing means. The vertical portion may be arranged so as to extend across the slot, and the second holding point may be formed to be variable in position.

  The present invention is advantageous in that it can provide an opening / closing mechanism for an opening / closing member that can be mounted at a position where the opening / closing member is largely opened / closed by mounting a gas spring having a smaller size and smaller reaction force in a narrow space.

  The washer 46 is fitted into the insertion portion 44b and is in contact with the outside of the upper engagement portion 38 to adjust the separation / connection between the engagement members. The E ring 47 is fitted into the ring retaining groove 44c and positions the collar 45, the upper engaging portion 38, and the washer 46 with respect to the head 44a and the flat plate portion 32c.

  FIG. 4 is an enlarged view showing the shape of the plate-like member 32 of the upper holding portion 33 serving as the engaging portion on the opening / closing panel 18 side in the opening / closing mechanism 20 having the above-described configuration. 4 shows a part of the main body cabinet 16 and the open / close panel 18 together with the open / close hinge 17, and the slot 31 shows a fitting portion of the collar 45 into the slot 31 by a two-dot chain phantom line. .

  In FIG. 4, the same components as those in FIGS. 1 and 3 are given the same reference numerals as those in FIGS. As shown in FIG. 4, the groove 31 of the plate-like member 32 has an upper edge 31 a having an arc shape. Here, the upper edge 31a is the edge farther (away from) the center of the opening / closing hinge 17 among the edges (two edges) of the longitudinal hole in the slot 31, and is the upper edge in FIG. It is. Further, the lower edge 31b is an edge of the slot 31 facing the upper edge 31a, and is the lower edge in FIG.

  The shape of the lower edge 31b of the slot 31 may follow the arc of the upper edge 31a as long as the fitting portion of the collar 45 into the slot 31 can easily slide in the slot 31. It may be linear as shown in FIG.

  In the slot 31, an end portion close to the opening / closing hinge 17 is set as a first holding point 48, and an end portion far from the opening / closing hinge 17 is set as a second holding point 49. The upper engaging portion 38 at the upper end of the gas spring 34 is locked to the first holding point 48 when the opening / closing panel 18 is closed, and is locked to the second holding point 49 when the opening / closing panel 18 is opened. It is configured to be movable.

  5A is a cross-sectional view taken along the line BB ′ of FIG. 1 showing in detail the engagement state between the lower end of the gas spring 34 and the main body cabinet 16 of the ATM 15 in the opening / closing mechanism 20 having the above-described configuration. FIG. 5 (b) is an exploded perspective view thereof.

  As shown in FIGS. 5 (a) and 5 (b), on both side surfaces of the main body cabinet 16, a part of the rotation fulcrum support portion 26 (51, 42, 39, washers 52, 53) of the lower stopper is provided. The head 51a of the stud 51 to be formed is fixed. The fixing position of the stud 51, that is, the rotation fulcrum support portion 26 is fixed to the inside of the main body cabinet 16 at a position lower than the biasing member holding portion 24 as shown in FIG.

  The lower stopper here is composed of a rotating member 27, a washer 52, and an E-ring 53 in addition to the stud 51. Further, the rotation fulcrum support portion 26 includes a stud 51, a lower engagement portion 42, a held hole 39, a rotation member 27, a rotation fulcrum / lower support hole 56, a washer 52, and an E ring 53. .

The stud 51 has a thick head 51a, a round bar-shaped insertion part 51b protruding from the head 51a, and a ring retaining groove 51c formed in the vicinity of the tip of the insertion part 51b.
The rotating member 27 is made of a plate member. The rotating member 27 is formed with a biasing member locking hole 54 in which the lower end portion of the spiral spring 25 (see FIG. 1) is locked to the rotating end portion 27a which is one end portion, in the vicinity of the other end portion. A notch portion 55 having an upward U-shaped cross section is formed, and a rotation fulcrum / lower support hole 56 serving as a rotation fulcrum and a lower support hole is formed below the notch portion 55.

  In this member configuration, the insertion portion 51b of the stud 51 is inserted into the held hole 39 of the lower engagement portion 42 at the lower end portion of the gas spring 34 and the rotation fulcrum / lower support hole 56 of the rotation member 27. A washer 52 is fitted to the tip of the insertion part 51b, and an E-ring 53 is fitted to the ring retaining groove 51c. At this time, the plate piece member 41 of the lower engaging portion 42 of the gas spring 34 is fitted into the upward U-shaped cutout portion 55 of the rotating member 27.

  FIG. 6A is a view taken in the direction of arrow D in FIG. 5A, and shows all the configurations of the lower holding portion 28 shown in FIG. 1 in addition to the configuration shown in FIG. FIG. 6B is a diagram illustrating the function of the lower holding portion 28 in the opening / closing mechanism 20 configured as described above. 6 (a) and (b), the same components as those in FIGS. 1 to 5 (a) and (b) are denoted by the same reference numerals as those in FIGS. 1 to 5 (a) and (b). It is given.

  As shown in FIG. 6A, the upper end portion of the spiral spring 25 is locked to the urging member holding portion 24 fixed to the main body cabinet 16. Further, the lower end portion of the spiral spring 25 is engaged with the rotation end portion 27 a of the rotation member 27.

The spiral spring 25 always generates a pulling force indicated by an arrow b. Thereby, the rotation end portion 27a of the rotation member 27 is urged to rotate as indicated by an arrow c.
On the other hand, the plate piece member 41 of the lower engaging portion 42 at the lower end portion of the gas spring 34 is fitted into the cutout portion 55 of the rotating member 27.

  When the rotation end portion 27a of the rotation member 27 is urged to rotate as indicated by an arrow c, the corner portion 55a on the rotation end portion side of the notch portion 55 becomes the rotation end portion side of the plate piece member 41. The corner 41a is pressed and urged as indicated by an arrow d.

  The pushing biasing force indicated by the arrow d is exaggerated for easy understanding in FIG. 6B, but the notch 55 is obtained when the rotating member 27 is rotated from the solid line position to the broken line position. This is the pressing force generated corresponding to the horizontal movement distance f of the corner portion 55a, that is, the corner portion 41a of the plate piece member 41 with respect to the held hole 39.

  This pressing biasing force is generated by the pressing biasing force applied from the corner portion 55 a of the notch portion 55 of the rotating member 27 to the corner portion 41 a of the plate piece member 41, the held hole 39 of the gas spring 34, and the plate piece member 41. A rotational force is generated on the held hole 39 formed by the distance between them.

  As shown in FIG. 2 (a), the rotational force applied to the lower end of the gas spring 34 from the rotating member 27 is indicated by the arrow at the upper end of the gas spring 34 that is in its maximum extension state and has zero reaction force. As shown by e, it becomes the force which moves to the outer side direction of the opening part 23 (refer FIG. 1) of the main body cabinet 16. FIG.

  In other words, the lower holding portion 28 is configured so that the upper end portion 37 of the gas spring 34 is moved into the first slot 31 shown in FIG. 4 when the opening / closing panel 18 is opened by the cooperation of the spiral spring 25 and the rotating member 27. The gas spring 34 is urged toward the outside of the opening (outside of the main body cabinet 16) so as to move from the holding point 48 to the second holding point 49.

  FIGS. 7A, 7B, and 7C are diagrams showing an operation state when the opening / closing panel 18 is opened in the opening / closing mechanism 20 having the above-described configuration. 7A shows a state in which the open / close panel 18 is completely closed, and FIG. 7B shows that the open / close panel 18 is opened by a human hand (hereinafter referred to as a human hand k) as indicated by an arrow k. 7 (c) shows a state in which the open / close panel 18 is fully opened by a human hand k.

  In FIGS. 7A, 7B, and 7C, the urging force indicated by the arrow b from the spiral spring 25 shown in FIG. Accordingly, the rotational force described with reference to FIGS. 6A and 6B is always generated around the held hole 39 in the held hole 39 of the lower engaging portion 42 of the gas spring 34.

  This rotational force is applied to the engaging portion of the upper end portion 37 of the gas spring 34 with the slot 31 via the collar 45 and the shaft member 44 shown in FIGS. 3 (a) and 3 (b). As shown in the enlarged view surrounded by the broken circles g, m, and n of 7 (a), (b), and (c), the moving force indicated by the arrow e is always generated.

  On the other hand, as shown in the enlarged view surrounded by the broken-line circle g in FIG. 7 (a), the upper end portion 37 of the gas spring 34 has a vertical upward force Y and a horizontal direction in addition to the moving force e. An inward force X (inward of the main body cabinet 16) is applied.

The vertical upward force Y and the horizontal inward force X are component forces of the extension force (reaction force) i of the gas spring 34 as shown in the enlarged view surrounded by the broken line circle j in FIG.
When the open / close panel 18 shown in FIG. 7A is closed, the extension force i applied to the upper end portion 37 of the gas spring 34 is larger than the moving force e accompanying the rotational force of the held hole 39 and the extension force. Both i and its component Y are large and upward.

  Furthermore, the upper holding portion 48 of the first holding point 48 of the slot 31 with which the upper end portion 37 of the gas spring 34 is engaged is located at the uppermost position than the other upper edge portion. Therefore, the upper end portion 37 of the gas spring 34 does not move in the slot 31 along the upper edge of the slot 31.

  As shown in FIG. 7B, when the human hand k opens the open / close panel 18 and pushes it up, the slot 31 moves upward, so that the tip of the gas spring 34 is stretched upward. . At this time, the gas spring extension force i becomes smaller than the moving force e of the tip, and the extension force i approaches zero.

  As shown in FIG. 7C, when the human hand k fully opens the open / close panel 18, the extension force i of the gas spring 34 becomes zero and the component force X also becomes zero. Thereby, the upper end portion 37 of the gas spring 34 is moved by the moving force e accompanying the rotational force of the held hole 39 as shown in the enlarged view surrounded by the broken line circle n. Move from the first holding point 48 to the second holding point 49.

  When the hand k of the person leaves the open / close panel 18, the open / close panel 18 tends to move in a direction to close by its own weight, that is, a direction to compress the gas spring 34. When the gas spring 34 is compressed, an extension force is generated again. Therefore, a position where the force for closing the opening / closing panel 18 and the extension force generated again is balanced is the fully opened position of the opening / closing panel 18. The fully open position of the open / close panel 18 shown in FIG. 7 (c) is actually the fully open position of the open / close panel 18 in which the above two forces are balanced.

  Thus, the upper end portion 37 of the gas spring 34 of this example is when the open / close panel 18 is fully opened with respect to the first holding point 48 that is the engagement point with the groove 31 when the open / close panel 18 is closed. The second holding point 48, which is the point of engagement with the slot 31, comes to the front of the open / close panel 18 opened from the first holding point 48 (upper right side in FIG. 7 c).

  That is, the holding position of the gas spring 34 with respect to the open / close panel 18 is closer to the open / close panel 18 (right side in FIG. 7 c) than the first holding point 48 with respect to the open / close hinge 17 of the open / close panel 18. The moment that supports the open / close panel 18 with respect to 17 can be made larger than that at the time of initial movement. As a result, it is possible to mount a small gas spring in a narrow space that has been difficult in the past.

  Further, in FIG. 7C, the upper edge portion of the second holding point 49 of the slot 31 with which the upper end portion 37 of the gas spring 34 engages is positioned at the uppermost position than the other upper edge portion. Yes. Therefore, unless an external force is applied, the upper edge 37 of the gas spring 34 that is urged outward by the moving force e by the rotational force of the held hole 39 has an upper edge. The opening / closing panel 18 is kept fully open without moving in the direction of the first holding point 48 that is at a lower position.

  FIGS. 8A to 8F are diagrams showing an operation state when the fully opened open / close panel 18 is closed in the open / close mechanism configured as described above. When the open / close panel 18 of FIG. 8A is fully opened, the upper end portion 37 of the gas spring 34 is engaged with the second holding point 49 of the slot 31.

  At this time, the straight line connecting the upper end portion and the lower end portion of the gas spring 34, that is, the axis is inclined inward of the main body cabinet 16 with respect to the vertical line 57 having the retained hole 39 at the lower end portion as a base point.

  Here, as shown in FIG. 8B, when the open / close panel 18 is pulled down by an external force, that is, a human hand k, the gas spring 34 is compressed. A reaction force i is generated in the compressed gas spring 34.

  From this reaction force i, as shown in a broken line circle q which is an enlarged view of a portion surrounded by a broken line circle p and a broken line circle s which is an enlarged view of a portion surrounded by a broken line circle r of the broken line circle q in FIG. A vertical component force Y and a horizontal component force X are generated. In the following, only the enlarged view indicated by the broken-line circle q is added to FIGS. 8C to 8F.

  As shown in FIG. 8C, when the opening / closing panel 18 is further pulled down by a human hand k, the gas spring 34 is further compressed, and the horizontal component force X increases with the reaction force i. This horizontal component force X is a force that pushes the upper end portion 37 of the gas spring 34 toward the first holding point 48 of the slot 31 as shown by arrows t in FIGS. .

  In addition, since the position of the upper edge of the second holding point 49 of the slot 31 is lower than the other upper edge, the upper end 37 of the second holding point 49 is held by the reaction force i of the gas spring 34 in the first holding position. A situation occurs in which it is easy to move toward the point 48.

  Then, as shown in FIG. 8 (e), the upper end portion 37 of the gas spring 34 moves to the first holding point 48. Thereafter, the open / close panel 18 is further pushed by a human hand k as shown in FIG. 8 (f), and the closed state shown in FIG. 7 (a) is restored.

  As described above, in the opening / closing mechanism of the opening / closing member of this example, it can be opened / closed only with one hand, and it is necessary to take the effort of pushing and pulling the gas spring with the other hand. It is easy to use and convenient.

  In addition, when the open / close member is fully opened, the upper end of the gas spring moves outward in the open direction of the open / close member from the initial movement, so that the support torque to the open / close member relative to the open / close hinge remains at the closed position. Since it becomes large compared with the case where it supports, even if it installs a small gas spring in a narrow space compared with the conventional gas spring, the opening-and-closing member can be greatly opened and supported.

  As a result, the operation, maintenance, and manufacturability of the main body device side to which the opening / closing mechanism is mounted are improved. In addition, by mounting a small gas spring, the mounting area of the gas spring can be used effectively, so that the main unit to which the opening / closing mechanism is mounted can be downsized.

  Similarly, since it can be used for the opening / closing mechanism of the opening / closing member of the same structure regardless of the size of the gas spring, there is no restriction on the space design in the opening / closing panel part of ATM or the like, for example, and the degree of freedom of design increases and is convenient. It is.

  FIG. 9 is a diagram illustrating the configuration of the engaging portion on the opening / closing panel side in the opening / closing mechanism of the opening / closing member according to the second embodiment. In FIG. 9, the same components as those shown in FIGS. 1 to 4 are denoted by the same reference numerals as those shown in FIGS. The engagement relationship between the lower end of the gas spring and the main body cabinet is the same as in the first embodiment.

  As shown in FIGS. 9 (a) and 9 (b), the slot 31 formed in the plate-like member 32, which is the upper engaging member of the opening / closing mechanism in this example, is longer in the longitudinal direction than in the first embodiment. It is formed long. An adjustment slot 58 is formed above the slot 31 along the arc of the upper edge of the slot 31.

  In the adjusting groove 58, the hook-shaped lateral portion 59a of the hook-shaped stopper fitting 59 is fixed by two screws 61 as fixing means. The fixing position is arbitrarily set along the adjustment slot 58. The vertical vertical portion 59b of the stopper fitting 59 is arranged so as to cover the groove hole 31, and the inner side of the vertical portion 59b forms a second second holding point 49.

  When the open / close panel 18 is fully opened, the gas spring 34 engages the upper end portion 37 with the second holding point 49 formed by the hook-shaped vertical portion 59 b of the stopper fitting 59 via the collar 45.

  In FIG. 9B, the stopper fitting 59 is moved toward the hinge 17 so that the length of the slot 31 is the same as the length of the slot 31 in the first embodiment. A state in which the second holding point is set at the same position as in the first embodiment is shown.

  When the gas spring 34 has a gas pressure (reaction force) that decreases with the passage of time, the stopper fitting 59 is moved away from the hinge 17 so that the gas spring 34 has a saddle shape at a position that matches the decreased gas pressure. The vertical portion 59 b (second holding point 49) is set, and the stopper fitting 59 is fixed to the adjustment groove 58.

  FIG. 9A shows a state in which the stopper fitting 59 has been moved to the outside of the slot 31. This position is a position where the fully openable open / close panel 18 can be supported by the gas spring 34 whose gas pressure has been reduced to the usable limit in the open / close mechanism of this example. Of course, fine adjustment can be made from the position of FIG. 9B to the position of FIG. 9A according to the degree of decrease in the gas pressure of the gas spring 34.

  As described above, according to the opening / closing mechanism of this example, the gas spring whose gas pressure is reduced due to the movement of the second holding point can be used. It is economical because there is no need to change the spring.

  Even if the gas pressure of the gas spring decreases, the movement of the second holding point allows the opening / closing panel to have a sufficient opening angle. Is easy and convenient.

  Even if a gas spring with a reduced gas pressure is used, the holding force can be ensured by moving the second holding point, so that there is no concern that the fully opened open / close panel will fall naturally, which is safe.

  In each of the above-described embodiments, the ATM has been described as an example, but the opening / closing mechanism of the opening / closing member of the present invention is not limited to this.

  The present invention can be used for all apparatuses having an open / close panel in the vertical direction.
