Description

  The present invention relates to a hinge of a detachable type (hinge pin insertion type) that supports a door of a game machine or the like so as to be openable and closable with respect to a main body.

  Conventionally, for example, as a hinge that supports the door of a slot machine so that it can be opened and closed, it is composed of a fixed member and a movable member. There is known a detachable hinge having a structure that protrudes downward and is fixed, and the pin is inserted into a bearing hole on the fixing member side and assembled. This hinge is usually attached to two places, an upper part and a lower part between the main body and the front door, because the shape of the game machine is large.

  In order to smoothly open and close the door of the slot machine, it is necessary to attach the rotary shafts of the two hinges mounted between the main body and the front door so that the axial center positions thereof are accurately aligned. Therefore, when two hinges are attached between the main body and the front door as described above, the two fixing members are fixed to the main body side with the axial center position of the bearing portion aligned, and the corresponding positions on the front door side are fixed. The two movable members have to be fixed with their pin centers accurately aligned, making it difficult and cumbersome to attach the hinges, and requiring a lot of time and man-hours.

  Accordingly, the inventors of the present invention are hinges composed of a vertically long fixed member and a movable member, and bearing portions each having a bearing hole at the upper and lower edge portions of the mounting plate portion of the fixed member each have an axial center position. Each pin is provided on the winding plate formed on the upper and lower edges of the mounting plate portion of the movable member so as to coincide with each other on the axis, and each pin has a shaft center position on one axis and the lower side. He proposed a hinge that was fixed by protruding into the bearing, and both pins were assembled by inserting them into the bearings of the fixing member.

  This hinge is constructed by providing bearing holes that serve as bearings on the upper and lower parts of the vertically long fixed member on the same axis and attaching pins on the same axial line on the upper and lower parts of the same vertically long movable member. When assembling the hinge, the front door to which the movable member is attached is lifted and simultaneously inserted into the upper and lower bearing holes of the stationary member on the main body side. For this reason, even if it is the front door of a heavy game machine, a hinge, ie, a front door, can be assembled | attached by aligning the axis | shaft of an up-and-down pin comparatively easily.

  By the way, as a hinge of this type, conversely to the above, pins are attached to the upper and lower parts of the vertically long fixed member on the same axis, and bearing holes serving as bearing parts are provided on the same axial line to the upper and lower parts of the vertically long movable member. The hinge of the structure provided in is known by the said patent document 1.

  In this type of hinge, the upper and lower bearing holes and the upper and lower pins are located on the same axis line of each member. Therefore, it is relatively easy to move the upper and lower bearings while holding the movable member. The upper and lower pins of the fixed member can be easily fitted into the upper and lower bearing holes and the upper and lower pins, but after the movable member is fitted into the bearing hole, the movable member is fixed The member can be rotated smoothly within a predetermined angle range with respect to the member.

  However, when this hinge is used as a hinge for the front door of a game machine such as a slot machine, the lower part of the opening on the front of the cabinet of this type of game machine protrudes forward and the upper part moves backward. It is formed so as to be inclined. For this reason, the hinge shaft tilts along the vertical edge of the tilted opening, so that when the operator opens the front door during maintenance and inspection, the hinge shaft tilts to rotate around the fulcrum. Therefore, when the opening angle of the front door is smaller than a predetermined angle, there is a problem that the front door closes due to its own weight.

  In view of this, a hinge for a game machine of this type has been proposed in Patent Document 2 and the like, which has a function of holding the door stationary with the door open.

  However, although this type of conventional hinge can be stationary with the door open using an elastically deformable member or a spring member, the door cannot be stationary at any angle other than a preset angle, When the spring elastic member or the holding member is plastically deformed by use, there is a problem that the stationary function of the door becomes uncertain.

  The present invention has been made in view of the above points, and even when the rotation shaft of the hinge is inclined and attached, even when the weight of the door is applied in the closing direction, the door can be opened lightly, and the door can be opened arbitrarily. It is an object of the present invention to provide a detachable hinge that can be stationary at an angle.

To achieve the above object, the hinge of the present invention is:
In a detachable hinge that is attached between a door that can be opened and closed and a main body, and is composed of a vertically long first member and a second member,
A bearing member having a bearing portion is fixed to at least an upper portion and a lower portion in the base frame of the first member so that the axial center position of the bearing hole coincides with one axis, and the mounting plate portion of the second member A hinge pin that can be fitted into the bearing member is fixed to at least the upper and lower edges of the shaft so that the axial center position coincides with one axis,
When the hinge pin of the second member is inserted into the bearing hole of the bearing member and assembled to the lower side or the upper side of the bearing member in the base frame of the first member, the first member and the second member are A door stopper device for stopping the rotation of the first member and the second member,
The door stopper device includes a first stopper portion attached to the first member or the second member, and a second stopper portion attached to the second member or the first member and coupled to the first stopper portion. With
The first stopper portion is inserted into an outer cylinder fixed in the case body via a cylindrical frictional resistance member so that the movable shaft can rotate with frictional resistance, and is attached to the tip of the movable shaft. It is configured with a fitting connection part,
The second stopper portion is configured such that the outer cylinder case is fitted on the outer peripheral portion of the fixed shaft via a one-way clutch so as to be rotatable only in one direction, and a fitting connection portion is provided at the tip of the outer cylinder case. ,
When connecting the first member and the second member, the fitting connection portion of the first stopper portion is fitted and connected to the fitted connection portion of the second stopper portion,
When the first member and the second member are rotated in the opening direction, the movable shaft of the first stopper portion does not rotate with respect to the case body, and the first member and the second member are interposed via the one-way clutch of the second stopper portion. The outer case rotates,
When rotating in a closing direction between the first member and the second member, the outer cylindrical case of the second stopper portion does not rotate with respect to the fixed shaft, and the case main body of the first stopper portion and The outer cylinder is frictionally rotated with respect to the movable shaft via the frictional resistance member.

  For example, the hinge is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, or vice versa, the second member is fixed to the door as a movable member. One member is used by being fixed to the main body as a fixing member. Further, for example, when the first member of the hinge is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, the pin provided on the winding portion of the second member is fixed upward. Conversely, when the second member of the hinge is fixed to the door as a movable member and the first member is fixed to the main body as a fixed member, the hinge pin provided on the winding portion of the second member is fixed downward.

  For example, when the hinge first member is fixed to the door as a movable member and the second member is fixed to the main body as a fixed member, hold the door and align the bearing hole of the movable bearing member with the hinge pin on the fixed member side Thus, the bearing member is aligned with its axial position, the axial line of the bearing hole is aligned with the axial line of the pin, and in this state, the position of the movable-side bearing member is slightly lowered, and the pin on the stationary member side is moved to the position of the movable-side bearing member. Fit into the bearing hole. At this time, in the door stopper device, the fitting connection portion of the first stopper portion is fitted and connected to the fitted connection portion of the second stopper portion.

  When the door is opened, the first member of the hinge is rotated with respect to the second member. In the first stopper portion of the door stopper device, the movable shaft does not rotate with respect to the friction resistance member due to the frictional resistance of the friction resistance member. The shaft rotates together with the first stopper portion including the friction resistance member, and the outer cylinder case of the second stopper portion connected to the movable shaft rotates in the rotation permission direction via the one-way clutch. For this reason, the door can be opened lightly to an arbitrary angle.

  When the door is attached to the main body and the hinge axis is inclined with respect to the vertical line, and the door's own weight is applied in the closing direction, if the door is released and the door's own weight is applied in the closing direction of the door The outer cylinder case of the second stopper portion of the door stopper device is braked in the closing direction of the door by the one-way clutch, the movable shaft of the first stopper portion does not rotate with respect to the friction resistance member due to the friction resistance of the friction resistance member, The door is stopped by its stopper function. Therefore, the door can be stopped at an arbitrary opening angle.

  On the other hand, when closing the door in the open state, if the door is pushed with a slight load, the outer case of the second stopper portion of the door stopper device does not rotate in the door closing direction by the one-way clutch. The movable shaft of the stopper portion does not rotate, and the frictional resistance member of the first stopper portion frictionally rotates with the outer shaft and the case body with frictional resistance with respect to the movable shaft, and rotates at a low speed to the closed position.

  Thus, when opening the door with respect to the main body, the outer cylinder case of the second stopper portion of the door stopper device rotates in the rotation permission direction via the one-way clutch, releases the hand from the door, and causes the door to its own weight. When the closing force is applied, braking by the one-way clutch is applied and the door stops, so the door can be stopped at an arbitrary angle, and when the stopped door is pushed in the closing direction, the first stopper portion of the door stopper device Since the frictional resistance member of this type, together with the outer cylinder and the case body, frictionally rotates while generating frictional resistance against the movable shaft, even the door urged by its own weight on the closed side can be safely closed to the closed position at a low speed. Can do.

  Here, the second stopper portion has a rotating shaft disposed in a fixed case through a one-way clutch so as to be rotatable only in one direction, and is fitted and connected to the tip of the rotating shaft. It is also possible to provide a part. In this case, the fitting connecting portion of the movable shaft of the first stopper portion is connected to the fitting connecting portion of the rotating shaft of the second stopper portion.

  Further, in the hinge, a fastening nut is screwed into an end of the movable shaft of the first stopper portion, and the frictional resistance member fitted on the movable shaft is clamped by a washer. The frictional resistance member can be pressed through the washer by the tightening force of the attaching nut to adjust the frictional force between the movable shaft and the frictional resistance member. According to this, the rotational frictional resistance of the movable shaft of the first stopper portion can be adjusted relatively easily according to the shape and load conditions of the door that can be opened and closed using a hinge.

  Further, in the hinge, the fixed shaft of the second stopper portion is fixed to the second member or the first member through a mounting bracket, and the mounting bracket has an outer cylinder case of the second stopper portion. It is possible to provide a rotation support portion that rotatably supports the fitted connection portion.

  Further, in the hinge, a fitting holding portion for preventing the rotation of the outer cylinder and fitting and holding the outer cylinder can be provided inside the case main body of the first stopper portion. According to this, the assembly which assembled | attached the movable shaft, the friction resistance member, the outer cylinder, etc. in the case main body of a 1st stopper part can be easily attached only by inserting.

  According to the hinge of the present invention, even when the rotation axis of the hinge is inclined and attached to the door and the weight of the door is applied in the closing direction, the door can be opened lightly and the door can be stopped at an arbitrary angle. be able to.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, this hinge is, for example, a vertically long hinge in which a movable member 1 serving as the first member and a fixing member 11 serving as the second member are detachably provided. As shown, for example, the movable member 1 is fixed to a door D of a game machine such as a slot machine, and the fixed member 11 is fixed and used inside a cabinet C of the game machine. As shown in FIG. 8, the movable member 1 has a channel-shaped base frame body 2 formed by bending a vertically long steel plate into a substantially U-shaped cross section. And the bearing member 3 which has the bearing hole 3a is respectively fixed to the lower part by rivet caulking.

  The base frame body 2 of the movable member 1 is formed into a long channel material shape having a substantially U-shaped cross section with an opening on the front side, and a bearing member is provided inside each of the upper portion, the middle portion, and the lower portion. 3 is fixed. The bearing member 3 is integrally formed in a substantially rectangular parallelepiped shape with a hard synthetic resin or the like, a recess is formed in the middle part, and a bearing hole 3a is formed downward in a horizontal plane part 3b which is the upper surface of the recess. A hinge pin 15 on the fixed member 11 side is fitted into the bearing hole 3a from below to constitute a bearing portion. In addition, the bearing member 3 may be provided on the same axis of two places, the upper part and the lower part of the movable member 1, or may be provided at four places.

  Further, a stopper portion 3c that can contact the lower surface of the shaft holding portion 13 or the hinge pin 15 protrudes from the lower portion of the bearing member 3. The hinge pin 15 of the fixing member 11 is fitted into the bearing hole 3a, and the fixing member 11 is inserted. When the movable member 1 is assembled to the movable member 1 and the movable member 1 is rotated to the closed state, the hinge pin 15 or the lower surface of the shaft holding portion 13 comes into contact with the movable member 1 so that the movable member 1 is not detached.

  The positions of the bearing holes 3a of the three bearing portions are located in the vicinity of one wall portion of the base frame body 2 and the rear wall of the bearing member 3, and when the hinge pins 15 of the shaft holding portion 13 described later are fitted, Are arranged so that their axial center positions coincide with each other. Such a bearing member 3 is fixed to fixed positions of the upper part, the intermediate part, and the lower part in the base frame 2 by rivets, fixing screws, and the like.

  The left side wall of the base frame 2 having a U-shaped cross section is formed wider than the right side wall. When the movable member 1 is attached to the door D of the game machine and used, the bearing member 3 and the shaft are held. The portion 13 is covered with the left side wall to prevent illegal acts such as inserting foreign objects through the gap between the cabinet C and the door D of the game machine and to increase the bending strength of the long base frame body 2. Further, when the door D is closed, the left side wall of the base frame body 2 comes into contact with the edge of the mounting plate portion 12 of the fixing member 11 and closes the gap between the cabinet C and the door D.

  Further, a movable stopper portion 20 serving as the first stopper portion of the door stopper device 5 is attached to the inside of the base frame body 2 of the movable member 1. As shown in FIGS. 5, 10, and 11, the movable stopper portion 20 has a cylindrical outer cylinder 24, a cylindrical frictional resistance member 23, and a fitting connection portion 22 a at the lower end portion in the case body 21. The shaft 22 is assembled. A movable shaft 22 is inserted into the outer cylinder 24 via a frictional resistance member 23, and the frictional resistance member 23 fitted on the movable shaft 22 is sandwiched between two washers 25 and 26 at the outer peripheral portion of the movable shaft 22. Then, the adjusted frictional resistance is generated between the frictional resistance member 23 and the movable shaft 22 by the tightening operation of the tightening nut 28 screwed into the upper end portion of the movable shaft 22.

  A plurality of spring washers 27 are inserted between the tightening nut 28 and the washer 25. As shown in FIG. 11, the frictional resistance member 23 is formed with a deformed cross-section in which the inner hole into which the movable shaft 22 is inserted is formed as a circular hole, while a plurality of protrusions are provided on the outer periphery, It is inserted and mounted in an outer cylinder 24 having an inner hole having the same shape as the modified cross section. Further, the frictional resistance member 23 is formed of a soft synthetic resin such as polyacetal resin, which is divided into two parts vertically as shown in FIG. 11, flanges are provided at the upper and lower ends, and upper and lower portions are provided in the inner hole of the outer cylinder 24. The movable shaft 22 is inserted through the inner hole of the frictional resistance member 23.

  As shown in FIGS. 5 and 11, the movable shaft 22 is inserted into the friction resistance member 23 inserted into the inner hole of the outer cylinder 24 from above and below, and two washers 25, 26, a spring washer 27 is externally fitted, and the friction resistance member 23 is clamped by washers 25, 26 from above and below. Since the fastening nut 28 is screwed onto the upper end portion of the movable shaft 22, the frictional resistance member 23 made of soft synthetic resin divided into two parts is pressurized by the fastening operation of the fastening nut 28, and the frictional resistance member 23 is pressed. The frictional resistance generated between the movable shaft 22 and the movable shaft 22 can be adjusted.

  As shown in FIG. 11, the case main body 21 of the movable stopper portion 20 is formed in a cover shape, and a fitting holding portion 21a is formed therein. The outer cylinder 24 of the movable stopper portion 20 is fitted to the fitting holding portion 21 a in the case main body 21 while being prevented from rotating, and the case main body 21 is fixed inside the base frame body 2 of the movable member 1. Moreover, the fitting connection part 22a provided in the lower end of the movable shaft 22 of the movable stopper part 20 is a to-be-fitted connection part 31a of the outer cylinder case 31 of the fixed stopper part 30 on the fixing member 11 side, as shown in FIG. To fit.

  As shown in FIG. 11, the case main body 21 is provided with a locking claw 21b and a mounting hole 21c. The case main body 21 is inserted into the movable member 1 and fixed to the locking claw 21b as shown in FIG. 9 with the assembly of the movable shaft 22 shown in FIG. A fixed position in the base frame 2 of the movable member 1 is fixed by a screw.

  Since the outer cylinder case 31 is rotatably mounted only in one direction (the opening direction of the movable member 1) via the one-way clutch 32, when the movable member 1 is rotated in the opening direction with respect to the fixed member 11, In the movable stopper portion 20, the case main body 21, the outer cylinder 24, the friction resistance member 23, and the movable shaft 22 are integrally rotated by the frictional resistance of the frictional resistance member 23, and are fixed stoppers connected to the movable shaft 22. The outer cylinder case 31 of the portion 30 is structured to rotate lightly in one direction of the one-way clutch 32.

  On the other hand, when the movable member 1 rotates in the closing direction with respect to the fixed member 11 and the movable stopper portion 20 rotates in the same direction, the outer cylinder case 31 of the fixed stopper portion 30 rotates in the non-rotating direction of the one-way clutch 32. Therefore, the frictional resistance member 23 of the movable stopper portion 20 is subjected to rotational force in the direction in which the movable member 1 is closed with respect to the movable shaft 22. At this time, an appropriate rotational frictional resistance is generated between the frictional resistance member 23 and the movable shaft 22, and the movable stopper portion 20, that is, the movable member 1 rotates together with the door D in the closing direction with an appropriate rotational resistance. ing.

  As shown in FIGS. 12 to 16, the fixing member 11 has a mounting plate portion 12 made of a vertically long strip-shaped steel plate, and an L-shaped cross-sectional portion 12 a extending on a side portion of the mounting plate portion 12. The mounting piece 12b is bent inward at the upper, middle, and lower portions of the side portion of the L-shaped cross section 12a, and the shaft holding portion 13 that holds the hinge pin 15 is attached to the mounting piece 12b. Composed. Each shaft holding portion 13 is formed by molding a synthetic resin so that the hinge pin 15 protrudes and holds upward, and the shaft holding portion 13 is provided with an attachment hole. As shown in FIG. Each shaft holding part 13 is attached using a fixing screw. At this time, each hinge pin 15 is attached with its axial center position aligned so that its axis passes on one axis along the longitudinal direction of the attachment plate portion 12. In addition, the shaft holding part 13 having the hinge pin 15 can be provided at two places only at the upper part and the lower part, and can also be provided at four places.

  Further, as shown in FIG. 15, a mounting piece 12c is provided near the lower portion of the L-shaped cross section 12a of the fixing member 11, and the fixing stopper portion 30 of the door stopper device 5 is attached to the mounting bracket 34 on this mounting piece 12c. Attached using. As shown in FIGS. 16, 17, and 18, the fixed stopper portion 30 includes a fixed shaft 33 that is fixed to the mounting piece 12 c of the fixing member 11, and an outer cylinder that is externally fitted to the fixed shaft 33 via a one-way clutch 32. The casing 31 includes a case 31 and a mounting bracket 34 that supports the outer cylinder case 31 so as to rotatably support the outer cylinder case 31.

  The fixed shaft 33 of the fixed stopper portion 30 is vertically fixed with a fixing screw on the mounting piece 12 c of the fixing member 11, and the outer cylinder case 31 is inserted into the outer peripheral portion of the fixed shaft 33 via the one-way clutch 32. As shown in FIG. 18, the mounting bracket 34 includes a rotation support portion 34 a for rotatably supporting the outer cylinder case 31, and supports the protrusion provided at the upper end of the outer cylinder case 31. The mounting bracket 34 is attached to the inner side of the mounting plate portion 12 of the fixing member 11 with a fixing screw so as to be inserted into the portion 34a and rotatably support the outer cylinder case 31.

  As the one-way clutch 32, for example, a roller-type one-way clutch is used. The one-way clutch 32 has a cam surface formed on the inner peripheral surface of the outer cylinder thereof, and a large number of rollers are arranged on the inner side of the one-way clutch 32 in the same axial direction as the fixed shaft 33, and each roller can be pressed against the cam surface by a spring. Each roller is configured to roll on the outer peripheral surface of the fixed shaft 33 only in one direction and to be locked to the fixed shaft 33 in the other direction. As shown in FIG. 5, the outer cylinder of the one-way clutch 32 is press-fitted and fitted into the outer cylinder case 31, and the fixed shaft 33 is press-fitted and fitted into the inner cylinder of the one-way clutch 32. As a result, the outer cylinder case 31 can be rotated with respect to the fixed shaft 33 via the one-way clutch 32 in the rotation allowable direction, and the rotation is locked in the rotation blocking direction.

  As shown in FIG. 17, a protruding portion is provided at the upper end of the outer cylinder case 31, and a fitting connection portion 31 a is formed as a rectangular hole on the upper surface of the protruding portion. When the hinge movable member 1 and the fixed member 11 are assembled, the fitting coupling portion 22a at the lower end of the movable shaft 22 of the movable stopper portion 20 is fitted into the fitting coupling portion 31a, and the movable member 1 is rotated. In other words, when the door D is opened and closed and the movable shaft 22 rotates, the turning power is transmitted to the outer cylinder case 31.

  That is, when the door D is opened with respect to the cabinet C, the fixed stopper portion 30 provided with the one-way clutch 32 rotates the outer cylinder case 31 in the rotation permission direction via the one-way clutch 32 and releases the door from the door D. When a closing force due to its own weight is applied to D, braking by the one-way clutch 32 is applied, and the movable member 1, that is, the door D is stopped.

  In the above embodiment, the fitting connecting portion 22a at the lower end of the movable shaft 22 of the movable stopper portion 20 is formed in a prismatic shape, and the fitting connecting portion 31a at the upper end of the outer cylinder case 31 is formed as a rectangular hole to be fitted. However, conversely, the fitting connecting portion at the lower end of the movable shaft can be formed as a rectangular hole, and the fitting connecting portion at the upper end of the outer cylinder case can be formed into a prismatic shape and fitted.

  As shown in FIG. 4, the hinge configured as described above is tightened by inserting a fixing screw into the mounting hole of the mounting plate 12 on the inner side of the left side wall of the opening of the cabinet C of the game machine. The movable frame 1 is fixed by tightening the base frame body 2 with a mounting screw at a position corresponding to the fixed member 11 inside the left end of the door D of the game machine.

  Then, with the door D opened, the bearing holes 3a of the upper, middle, and lower bearing members 3 of the hinge movable member 1 are fitted to the upper, middle, and lower hinge pins 15 of the fixed member 11 of the cabinet C, and FIG. As shown in FIG. 2, the hinge is assembled and the door D is attached to the cabinet C. At this time, the door D is held so that the bearing member 3 is first aligned with the shaft holding portion 13 on the fixing member 11 side and the inner wall of the concave portion of the bearing member 3 is brought into contact with the side surface of the shaft holding portion 13 of the fixing member 11. To adjust the axial center position of the hinge pin 15 to the axial center position of the bearing hole 3a, and if the position of the door D is slightly lowered in this state, the hinge pin 15 automatically enters and fits into the bearing hole 3a. Thus, the hinge can be easily assembled.

  Furthermore, when the hinge movable member 1 and the fixed member 11 are assembled, the fitting connection portion 22a at the lower end of the movable shaft 22 of the movable stopper portion 20 is connected to the fitting connection portion 31a at the upper end of the fixed shaft 33 of the fixed stopper portion 30. As shown in FIG. 5, the door stopper device 5 has a movable stopper portion 20 and a fixed stopper portion 30 connected to each other. When the movable member 1 rotates, that is, the door D is opened and closed, and the movable shaft 22 of the movable stopper portion 20 is moved. When it rotates, the turning force is transmitted to the outer cylinder case 31 of the fixed stopper portion 30.

  When the door D is opened in this state, the hinge movable member 1 rotates with respect to the fixed member 11, and the movable stopper portion 20 of the door stopper device 5 has a frictional resistance caused by the frictional resistance of the frictional resistance member 23. The movable shaft 22 rotates together with the movable stopper portion 20 including the frictional resistance member 23 without rotating relative to the member 23, and the outer cylinder case 31 of the fixed stopper portion 30 connected to the movable shaft 22 is interposed via the one-way clutch 32. It rotates in the rotation permission direction. For this reason, the door D can be opened lightly to an arbitrary angle.

  In the case of a gaming machine such as a slot machine, the door D is mounted so that the axis of the hinge pin is inclined with respect to the vertical line of the cabinet C, the axis of the hinge pin 15 is inclined with respect to the vertical line, and the dead weight of the door D is closed. Take it. In such a case, when the hand D is released from the door D and the weight of the door D is applied in the closing direction of the door D, the outer case 31 of the fixed stopper portion 30 of the door stopper device 5 is closed by the one-way clutch 32 in the closing direction of the door D. The movable shaft 22 of the movable stopper portion 20 is not rotated with respect to the frictional resistance member 23 by the frictional resistance of the frictional resistance member 23, and the door D is stopped by the stopper function. Therefore, the opened door D can be stopped at an arbitrary opening angle.

  On the other hand, when closing the door D in the open state, when the door D is pushed toward the closing side with a slight load, the outer cylinder case 31 of the fixed stopper portion 30 of the door stopper device 5 is moved in the closing direction of the door D by the one-way clutch 32. Since it does not rotate, the movable shaft 22 of the movable stopper portion 20 does not rotate, and the frictional resistance member 23 of the movable stopper portion 20 frictionally rotates together with the outer cylinder 24 and the case body 21 with frictional resistance against the movable shaft 22 at a low speed. Rotate to the closed position.

  Thus, when opening the door D with respect to the cabinet C, the outer cylinder case 31 of the fixed stopper portion 30 of the door stopper device 5 rotates in the rotation permission direction via the one-way clutch 32, and the hand is moved from the door D. When the closing force due to its own weight is applied to the release door D, braking by the one-way clutch 32 is applied and the door D stops, so that the door D can be stopped at an arbitrary angle. Further, when the stopped door D is pushed in the closing direction, the frictional resistance member 23 of the movable stopper portion 20 of the door stopper device 5 frictionally rotates together with the outer cylinder 24 and the case body 21 while generating a frictional resistance with respect to the movable shaft 22. Therefore, even the door D urged by its own weight on the closed side can be safely closed to the closed position at a low speed.

  19 and 20 show a fixed stopper portion 40 of another embodiment of the door stopper device. In the fixed stopper portion 30 of the above embodiment, the outer cylinder case 31 is rotated, but in the fixed stopper portion 40 of this example, the rotation shaft 43 is rotated via the one-way clutch 42 instead of the outer cylinder case 31. It has a structure to do. In addition, about the part similar to the said embodiment, the code | symbol similar to the above is attached | subjected to a figure, and the description is abbreviate | omitted.

  The fixed stopper portion 40 has a rotating shaft 43 disposed in a fixed fixing case 41 via a one-way clutch 42 so as to be rotatable only in one direction, and is fitted to the tip of the rotating shaft 43. The connecting portion 43a is provided.

  As shown in FIGS. 19 and 20, the fixed case 41 is formed in a substantially cylindrical shape and fixed to a mounting piece 12 c provided on the mounting plate portion 12 of the fixing member 11, and the one-way clutch 42 is provided in the fixed case 41. Is press-fitted and the outer cylinder is fitted to the fixed case 41. The rotation shaft 43 is inserted into the one-way clutch 42 so as to be rotatable only in the rotation allowable direction, and is attached so as to be locked in the rotation prevention direction. A concave fitting connection portion 43 a is provided on the large diameter portion at the upper end of the rotation shaft 43. In a state where the hinge movable member 1 and the fixed member 11 are assembled, the fitting connection portion 22a of the movable shaft 22 of the movable stopper portion 20 described above is connected to the fitting connection portion of the rotating shaft 43 of the fixed stopper portion 40. It will be connected with 43a.

  Therefore, similarly to the above, when the door D is opened, the hinge movable member 1 rotates with respect to the fixed member 11, and the movable stopper portion 20 of the door stopper device 5 has the movable shaft 22 having the friction resistance of the friction resistance member 23. , The movable shaft 22 rotates together with the movable stopper portion 20 including the friction resistance member 23, and the rotating shaft 43 of the fixed stopper portion 40 connected to the movable shaft 22 is replaced with the one-way clutch 42. It rotates in the rotation permission direction via. For this reason, the door D can be opened lightly to an arbitrary angle.

  On the other hand, when the hand is released from the opened door D and the dead weight of the door D is applied in the closing direction of the door D, the rotating shaft 43 of the fixed stopper portion 40 of the door stopper device 5 is closed by the one-way clutch 42 in the closing direction of the door D. The movable shaft 22 of the movable stopper portion 20 is not rotated with respect to the frictional resistance member 23 by the frictional resistance of the frictional resistance member 23, and the door D is stopped by the stopper function. Therefore, the opened door D can be stopped at an arbitrary opening angle.

  On the other hand, when closing the door D in the open state, when the door D is pushed toward the closing side with a slight load, the rotation shaft 43 of the fixed stopper portion 40 of the door stopper device 5 is moved in the closing direction of the door D by the one-way clutch 42. Since it does not rotate, the movable shaft 22 of the movable stopper portion 20 does not rotate, and the frictional resistance member 23 of the movable stopper portion 20 frictionally rotates together with the outer cylinder 24 and the case body 21 with frictional resistance against the movable shaft 22 at a low speed. Rotate to the closed position.
