Description

  The present invention attaches a curtain covering the top of a gaming machine installation island (hereinafter abbreviated as “game island”) on which a gaming machine such as a pachinko or pachislot is installed, so that the curtain can be opened and closed. The present invention relates to a hinge part capable of maintaining an open state, and a game island including the same.

  Conventionally, it is most common that a plurality of gaming machines represented by pachinko machines and pachislot machines are arranged side by side along the longitudinal direction of a substantially rectangular parallelepiped gaming island. As for pachinko machines, by constantly replenishing the required pachinko balls from the replenishment rods installed above the amusement island, even if a large number of pachinko balls are discharged in a short time, a shortage of balls will be caused. You can continue playing. Also, in recent years, pachislot machines have also adopted a method of mechanically supplying medals through a replenishment cage provided inside the amusement island, eliminating the need for manual medals replenishment by the staff at the game hall. There are also amusement islands that make it possible to avoid interruptions.

  The replenishment cage provided on the upper part of the game island is covered by a plurality of curtains arranged side by side along the longitudinal direction of the game island. To prevent contact. However, when the game medium is jammed or the maintenance of the replenishment bowl, the curtains need to be openable and closable so that the game room staff can access the replenishment bowl. Moreover, since the curtain is located at the upper part of the game island with high visibility, it has a function of improving the design of the game island by decorating the outer surface.

  As a member for attaching the curtain to the game island so as to be freely opened and closed, an opening / closing device described in Patent Document 1 below is representative. The conventional opening / closing device 110 shown in FIG. 5 is a hinge that attaches the upper part of the curtain to the Kamoi of the game island so that it can be opened and closed, and moves to the base metal fitting 120 having a substantially horizontal slide long hole 132 and the slide long hole. It is comprised from the slide member 140 which has the axis | shaft 142 engaged freely. By providing this opening / closing device, for example, at two locations in the width direction along the upper side of the curtain plate, the curtain plate can be pivoted about its upper side to be opened and closed. Further, the curtain plate can be kept open by pushing the upper surface of the game island inward along the slide long hole 132 with the curtain plate opened to substantially horizontal. A locking portion 134 is formed at the rear end of the slide long hole 132 and can be locked with the shaft 142 by being engaged with the shaft 142.

  On the other hand, in recent years, in order to realize an original layout for each amusement hall, as shown in Patent Document 2 below, a curved shape or a bent shape in which a part or all of adjacent gaming machines are bent and arranged with respect to each other. Amusement islands such as shapes (hereinafter referred to as “R islands”) have been proposed. Since the R island has a curved or bent shape as a whole along the longitudinal direction in which the gaming machines are arranged side by side, the normal direction of the adjacent curtain plates is set to a predetermined bending angle with respect to the curtain plate provided on the upper part. It will be installed continuously while bending. Further, the outer shape of the R island can be bent by making the curtain plate a flat plate, and the outer shape of the R island can be curved by making the curtain plate a curved plate.

  However, when the curtain plate provided to be openable and closable with respect to the R island has a concave shape or a convex shape in accordance with the curved or bent shape of the R island, the curtain plate may be R depending on the opening and closing device described in Patent Document 1. It becomes difficult to attach to the island. That is, in the case of the conventional opening / closing device 110 shown in FIG. 5, the joint portion 144 that contacts the curtain plate of the slide member 140 is formed wider than the interval between the opposed slide long holes 132, and the curtain plate is screwed. Since the screw holes 146a and 146b for fastening are provided side by side in the width direction of the switchgear 110, when the switchgear 110 is attached at two locations along the upper side of the curtain plate, four screw holes are provided. This is because they are aligned on a straight line and cannot be adapted to the curved shape of the curtain. In other words, the conventional curtain opening and closing device is manufactured on the premise that the gaming machines are used on a straight island installed side by side in a straight line, and is attached to a game island other than a smooth flat plate shape, for example. There is a problem in that a curtain with a curved surface (inner surface) cannot be freely opened and closed.

  The present invention has been made to solve the above problems, that is, whether the game island is an R island or a straight island, and whether the mounting surface of the curtain plate is flat or curved. It is an object of the present invention to provide a highly versatile mounting part capable of opening and closing a curtain plate so as to be freely opened and closed with respect to the game island, and a game island including a curtain plate attached using the same. Is.

  The present invention follows the basic structure of a sliding hinge comprising a base member fixed to an amusement island and a sliding member that is slidably supported with respect to the base member. By forming the curtain plate fixing piece in contact with the joint portion 144 of the conventional switchgear 110, the slide member can be used as the curtain plate even when the mounting surface of the curtain plate is curved in the width direction, for example. It is characterized in that it can be joined.

  FIG. 1 is a partial schematic view of a game island 90 including a curtain opening / closing hinge 10 according to the present invention. The gaming island 90 is an R island, and a plurality of gaming machines 100 are arranged in a bent manner along the curved arcuate longitudinal direction indicated by double-sided arrows in FIG. The magnitude of the bending angle defined by the angle formed by the normals of the machine surfaces of adjacent gaming machines 100 is not particularly limited, and in the present invention, the angle can be 5 to 10 degrees or more. .

  A replenishment basket 92 is installed above the game island 90 along the longitudinal direction thereof, and a game medium such as a pachinko ball (not shown) is transferred and distributed to the game machines 100. The supply basket 92 is covered with a curtain 91 that is suspended from the upper side surface of the game island 90. This figure shows a state in which only one of the plurality of curtains 91 provided side by side along the longitudinal direction of the game island 90 is opened substantially horizontally.

  A curtain opening / closing hinge 10 of the present invention for attaching the curtain 91 to the game island 90 which is an R island or a straight island is openable and closable. The top plate 93 of the game island 90, a structural member such as a duck, a girder or a column. Among these, it fixes with respect to the horizontal surface which exists in a position higher than the replenishment rod 92, or a substantially horizontal surface. By fixing the upper end portion of the curtain plate 91 at a position higher than the replenishing rod 92, the replenishing rod 92 can be covered. In the figure, one curtain plate 91 for each width of the gaming machine 100 is provided on the top surface of the top board 93 along the longitudinal direction of the game island 90 by two curtain plate opening / closing hinges 10. .

FIG. 2 is a top perspective view of the curtain opening / closing hinge 10 according to the embodiment of the present invention.
The curtain opening / closing hinge 10 includes a base member 20 fixed to the upper surface of the top plate 93 of the game island 90, guides 30 provided opposite to both sides in the width direction, and a longitudinal direction along the guide 30. A slide member 40 that slides, and a slide shaft 42 that pivots the slide member 40 relative to the guide 30 so as to be slidable and rotatable are provided. The width direction of the curtain opening / closing hinge 10 shown in the figure corresponds to the longitudinal direction of the game island 90, and similarly the curtain plate opening / closing hinge 10 corresponds to the depth direction of the game island 90. Is attached to the game island 90.

  The base member 20 is attached and fixed to the amusement island 90 horizontally or substantially horizontally. The fixing means is not particularly limited. For example, the fixing means may be screw fixing using a screw hole (not shown), adhesive fixing, or a combination of both. Further, it may be fixed directly to the top plate 93 of the game island 90 or may be fixed through an attachment member such as a spacer or a bracket.

  The guide 30 is a member provided with a slide groove for sliding a slide member 40 having a slide shaft 42 extending in the width direction in the front-rear direction of the curtain opening / closing hinge 10. A specific aspect of the sliding groove is not particularly limited as long as it has such a function. For example, in the present embodiment shown in FIG. 2, an upright surface 36 erected by bending both ends of the base member 20 extending in the front-rear direction at right angles and a long hole formed in the upright surface 36 so as to extend in the front-rear direction. 32 is used as a sliding groove. In addition, the slide shaft 42 is sandwiched between the guide groove having the long hole 32 as a retaining hole instead of the through-hole and the two guide plates protruding from the vertical surface 36 and extending in the front-rear direction, thereby guiding this in the front-rear direction. An aspect may be sufficient.

  A rib 38 is provided in parallel to the base member 20 by further bending the upper side of the vertical surface 36 to reinforce the vertical surface 36, and an open curtain plate 91 can be placed as will be described later. Further, a locking portion 34 is formed at the rear end portion of the long hole 32 extending in the front-rear direction so as to bend upward. As will be described later, the locking portion 34 locks the slide shaft 42 to keep the curtain plate 91 open (see FIG. 4).

  The slide shaft 42 is slidably and pivotally mounted on a slide groove specifically formed by the long hole 32 or the like. In FIG. 2, the slide member 40 is mounted from the outside of the opposing guide 30, and one slide shaft 42 inserted through the pair of long holes 32 is formed between both end portions 47, 47 in the width direction of the slide member 40. The delivered mode is illustrated. In addition, the slide shaft 42 may be configured by projecting and providing cylindrical bosses whose axial centers coincide with each other at the end portion 47 in the width direction of the slide member 40. That is, as long as the slide shaft 42 is provided so as to be slidable and rotatable with respect to the slide groove, it may be composed of a single shaft rod as shown or may be divided.

  The slide member 40 is a movable member that is coupled to the curtain plate 91 and is slidably and rotatably connected to the guide 30 via the slide shaft 42 to open or close the curtain plate 91. A curtain plate fixing piece 44 coupled to the slide shaft 42 and a connecting portion 48 coupled to the slide shaft 42 are provided. The curtain opening / closing hinge 10 according to the present invention has a width corresponding to the interval between the opposing guides 30 at the connecting portion 48, whereas the width of the curtain plate fixing piece 44 is larger than the interval between the guides 30. The curtain plate fixing piece 44 has a plurality of screw holes 46 (46a, 46b) for screwing the curtain plate 91 on the slide shaft 42. A second feature is that they are provided side by side in a direction orthogonal to the axial direction.

  Specifically, in the present embodiment, a curtain plate fixing piece 44 having a width dimension that is not less than one time and not more than twice a seat surface diameter of a screw (see FIG. 4) for screwing the curtain plate 91 is used. The width of the curtain plate fixing piece 44 may be not less than one time and not more than twice the diameter of the screw hole 46.

  In the conventional opening / closing device (hinge) 110 shown in FIG. 5, the width dimension of the slide member 140 screwed to the curtain plate 91 is formed to be equal to or greater than the interval between the slide long holes 132. It suffices that the screw seat surface for fixing the curtain plate 91 can apply the fastening force to the curtain plate fixing piece 44 sufficiently and sufficiently by forming it with a very narrow width.

  That is, the slide member 40 is formed in, for example, a T-shape, and includes an elongated curtain plate fixing piece 44 extending in a direction perpendicular to the slide axis, and a connecting portion 48 extending from the base end portion 44b to both sides in the width direction. With this configuration, the slide member 40 can be rotated around the axis of the slide shaft 42 along the connecting portion 48, and the tip end portion 44 a can be suspended or pulled with respect to the base member 20. Further, since the slide shaft 42 can slide back and forth with respect to the long hole 32, the slide member 40 is lifted so that the tip end portion 44 a of the slide member 40 does not collide with the base member 20. The member 20 can be pushed and pulled back and forth.

  FIG. 3 is a perspective view showing a state where the curtain plate opening / closing hinge 10 is attached to the curtain plate 91. The curtain 91 has a curved shape in accordance with the overall shape of the R island. In the figure, a curtain opening / closing hinge 10 is attached to the outside of the curved shape, and FIGS. 1 and 3 correspond to each other. However, in FIG. 3, for simplicity, the curtain plate 91 is illustrated as a curved plate having a uniform thickness.

  1 and 3 show a state in which the direction of the surface of the gaming machine 100 is gathered at the center of the curve (hereinafter referred to as “inner R side” and the outer side of the curve is referred to as “outer R side”). The game island 90 and the curtain 91 are shown. Therefore, since the curtain plate 91 is attached to the game island 90 with the inner R side facing the player, the curtain plate opening / closing hinge 10 is attached to the outer R side of the curtain plate 91 which is the back surface thereof. On the other hand, on the outer R side, which is the opposite side of the game island 90, the gaming machine 100 is installed so that the direction of the machine surface is dissipated to the outside of the curve, and the curtain 91 is also external to the player. It is attached to the game island 90 with the R side facing. Therefore, in such a case, the curtain plate opening / closing hinge 10 is attached to the inner R side of the curtain plate 91. It should be noted that the curtain plate opening / closing hinge 10 of the present invention can be attached to the R island so that the curtain plate 91 can be opened and closed freely in any of the above embodiments. Further, the curvature of the game island 90 and the curtain 91 is not particularly limited, and the curtain 10 is also used for the game island 90 (that is, a straight island) with extremely small curvature using the curtain 10 for opening and closing the curtain. 91 can be attached to the game island 90.

  The curtain plate fixing piece 44 and the connecting portion 48 according to the present embodiment are formed in a flat plate shape. The curtain plate fixing piece 44 and the connecting portion 48 may have a concave surface or a convex shape curved in the width direction in accordance with the curvature of the curtain plate 91 to be attached, but the curtain plate 91 is a flat plate or a curved plate. Furthermore, from the viewpoint of enabling the curtain opening / closing hinge 10 to be used universally regardless of the curvature or the direction of the unevenness, the curtain plate fixing piece 44 and the connecting portion 48 are formed in a flat plate shape as shown in the figure. However, it is preferable to make the curtain plate fixing piece 44 narrow. Further, the curtain plate fixing piece 44 and the connecting portion 48 may be formed as separate members and joined to each other. However, the number of parts can be reduced by forming them integrally by punching a metal material, for example.

  In the conventional opening / closing device 110, the screw holes 146a and 146b for fastening the curtain plate 91 are provided side by side in the width direction, whereas in the case of the present embodiment, the elongated curtain plate fixing piece 44 is provided. Screw holes 46a and 46b are provided vertically (in the direction perpendicular to the slide axis). As a result, as shown in FIG. 3, the inner R side or outer R side surface of the curved curtain plate 91 and the plurality of screw holes 46 of the curtain plate fixing piece 44 are center axes of the curved shape of the curtain plate 91. It will be in the state of the line contact along a direction (up-down direction in a figure). Therefore, in the case of the present invention, the curtain plate fixing piece 44 can be fixed to the curtain plate 91 regardless of whether or not the curtain plate 91 is curved and the curvature thereof.

  The curtain plate fixing piece 44 and the curtain plate 91 may be directly abutted and fixed with screws, or a spacer having a predetermined thickness according to the curvature of the curtain plate 91 may be interposed. In particular, when the curtain plate fixing piece 44 and the connecting portion 48 are both brought into contact with the curtain plate 91 to fix them, and the slide member 40 is fixed to the inner R side (concave surface) of the curtain plate 91. In order to prevent the coupling portion 48 and the concave shape of the curtain plate 91 from interfering with each other, it is preferable to secure a clearance with the coupling portion 48 by interposing a spacer between the curtain plate fixing piece 44 and the curtain plate 91.

  By providing a plurality of curtain plate opening / closing hinges 10 in the width direction (longitudinal direction in the game island 90 shown in FIG. 1), the curtain plate 91 can be stably and rotatably fixed. In the present embodiment shown in FIG. 3, the curtain plate fixing pieces 44 of the two types of curtain plate opening / closing hinges 10 are joined to each other at both ends in the width direction of the upper end of the curtain plate 91.

Here, as a mode of attaching the curtain plate opening / closing hinge 10 to the curtain plate 91, one of the following two methods may be adopted.
(I) The direction of the tangent in the width direction of the curtain plate 91 at the position where the screw hole 46 abuts is aligned with the axial direction of the slide shaft 42, that is, the slide shaft in the curved tangential direction of the curtain plate 91. 42, a plurality of types of curtain plate opening / closing hinges 10 provided on the curtain plate 91 are attached to each other in a letter C shape or a radial shape (aspect of FIG. 3).
(Ii) A mode (not shown) in which a plurality of types of curtain plate opening / closing hinges 10 are attached to the curtain plate 91 such that the axis of each slide shaft 42 coincides, that is, the curtain plate opening / closing hinges 10 are arranged side by side.

  In the case of the above (i), the plane including the curtain plate fixing piece 44 comes into contact with the curtain plate 91, and the curtain plate fixing piece 44 and the curtain plate 91 face each other. There is an advantage that screwing is performed firmly. However, in this case, when the curtain plate 91 rotated so as to lift the lower end is slid along the long hole 32 and pushed in, the distance in the width direction between the curtain plate fixing pieces 44 varies (in the case of FIG. 3 gradually). Therefore, in the curtain opening / closing hinge 10, it is preferable to provide a predetermined clearance in the width direction between the slide member 40 and the guide 30 to absorb the fluctuation.

  In the case of (ii), since the distance in the width direction between the curtain plate fixing pieces 44 does not change even if the curtain plate 91 is slid along the long hole 32, the slide member 40 and the guide are provided on the curtain plate opening / closing hinge 10. It is not necessary to provide a required clearance with 30. When the curtain plate fixing piece 44 and the curtain plate 91 are not in direct contact with each other, a spacer formed in a wedge shape or the like may be interposed between the curtain plate fixing piece 44 and the curtain plate 91.

  4A to 4D are schematic views showing how the curtain plate 91 is opened and fixed. It is sectional drawing which shows the state which cut | disconnected the game island 90 perpendicularly | vertically with respect to the longitudinal direction, and the curtain 91 is shown in flat form for simplicity.

  FIG. 4A shows a state in which the curtain 91 is suspended from the game island 90. In the curtain plate opening / closing hinge 10, the base member 20 is placed and fixed on, for example, a top plate 93 of the game island 90, and the slide shaft 42 is in a position where it is pulled out to the front end of the long hole 32. The slide member 40 hangs down from the front surface (right side surface in the figure) of the game island 90 and is coupled to the curtain plate 91 by two screws 50 provided vertically. As a result, the internal structure of the game island 90 is covered with the curtain 91. FIG. 4B shows the state in which the leading end (lower end) of the curtain plate 91 is lifted from this state and rotated around the slide shaft 42 to open the screen.

  In FIG. 4B, the curtain plate 91 rotates around the slide shaft 42 by pulling up the tip until the normal direction of the curtain plate 91 is directed vertically upward, that is, until the curtain plate 91 is in a horizontal state. ing. As a result, the inside of the game island 90 is exposed, and for example, the replenishment basket 92 (see FIG. 1) can be cleaned and maintained.

  With the curtain opening / closing hinge 10 according to the present embodiment, the clearance between the connecting portion 48 and the guide 30 is upright in the state shown in FIG. 4B in which the curtain plate fixing piece 44 is positioned horizontally with respect to the base member 20. It is larger than the clearance in the height direction between the inner edge of the long hole 32 provided in the surface 36 and the slide shaft 42, and the connecting portion 48 and the guide 30 are not in contact with each other. As a result, when the curtain plate 91 is pushed horizontally in the direction of the arrow from the state shown in the figure, the slide member 40 and the guide 30 come into contact with each other only via the slide shaft 42, and the lubricity of the slide shaft 42 is improved. By doing so, the sliding friction of pushing or pulling out the curtain plate 91 can be reduced.

  In reducing the sliding friction and / or rolling friction of the slide shaft 42, a metal material having a small friction coefficient is used for the slide shaft 42 and the guide 30 and the slide member 40 in contact with the slide shaft 42, and the guide 30 and the slide shaft in contact with each other. 42 and the slide shaft 42 and the slide member 40 may be made of different materials. This is to prevent the frictional resistance from increasing due to the metal bond generated at the interface between the same kinds of metals. The slide shaft 42 is preferably made of a material excellent in mechanical strength because it receives a shearing force from the periphery of the long hole 32 at the terminal end (front end or rear end) of pushing or pulling out. ) From a cylindrical material. On the other hand, the base member 20, the guide 30, and the slide member 40 are different from the slide shaft 42. For example, pickled steel sheets can be used from the viewpoint of improving strength, workability, and plating properties.

  FIG. 4C shows a state where the tip of the curtain plate 91 is further pulled up from the horizontal state.

  The slide member 40 of the present embodiment is characterized in that the tip end portion 44a of the curtain plate fixing piece 44 can be lifted upward from the horizontal position as shown in FIG. This is because the curtain plate fixing piece 44 and the connecting portion 48 are formed in a T shape, that is, the connecting portion 48 is opposite to the curtain plate fixing piece 44 (the upper side 49 of the connecting portion 48 in the perspective view of FIG. 2). This is because it is flat at least in the vicinity of the end portion 47 that may interfere with the guide 30 and is not provided with a projection as in the conventional opening / closing device 110 shown in FIG. That is, by making the upper side 49 of the connecting portion 48 flat, a large clearance from the rib 38 of the guide 30 is ensured, so that the curtain plate fixing piece 44 and the curtain plate 91 can be pulled up at an angle exceeding the horizontal.

  As a result, in FIG. 4C, the tip of the curtain plate 91 faces upward from the horizontal direction, and the screw 50 or the lower surface of the curtain plate 91 (the inner surface of the game island 90) may interfere with the curtain plate opening / closing hinge 10. Therefore, the operator can easily push the curtain plate 91 into the back of the game island 90 by smoothly sliding the slide shaft 42 backward (in the direction of the arrow) along the long hole 32.

  FIG. 4D shows a state in which the curtain plate 91 is pushed into the game island 90 as far as possible.

  In FIG. 4D, the slide shaft 42 pushed to the rear end of the long hole 32 receives a push-up load as a reaction of the curtain plate 91 whose tip is about to hang down by its own weight. The curtain plate 91 is restricted from being pulled out and closed by its own weight. Thus, since the curtain plate 91 does not close unexpectedly, an operator who cleans the replenishment rod inside the game island 90 can work with confidence in the open state of the curtain plate 91.

It is a partial schematic diagram of amusement island 90 provided with hinges 10 for opening and closing the curtain plate. It is a perspective view of hinge 10 for curtain opening / closing. It is a perspective view which shows the state which attached the hinge 10 for curtain opening / closing to the curtain 91. FIG. (A)-(d) It is a schematic diagram which shows a mode that the curtain plate 91 is open | released and fixed. It is an upper perspective view of the conventional opening / closing device 110.
