Abstract

<P>PROBLEM TO BE SOLVED: To provide a pachinko ball recovery device which enables a smooth discharge of the pachinko balls from the ball discharge part while eliminating the jamming with the game balls on the downstream side of the ball discharge part even when the ball discharge part has a long distance at which the pachinko balls roll in one row. <P>SOLUTION: The bottom surface part 17 of the ball discharge part 11 is formed as a gentle gradient section 19 in which the prescribed section on the downstream side is gentle in the gradient while being formed as steep gradient sections 18, steeper in the gradient, in the sections other than the gentle gradient section 19. When the jamming with the game balls occurs, the pachinko balls flowing down faster in the steep gradient sections 18 hit the pachinko balls causing the jamming to eliminate it by the impacts and vibrations generated. When no jamming with the pachinko balls occurs, the downflow speed of the pachinko balls is reduced through the gentle gradient section 19 and causes no irregular bouncing of the pachinko balls or the like at the location where the pachinko balls run down straight, thereby enabling the smooth discharge of the pachinko balls from the ball discharge part 11. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention provides a ball receiving portion for receiving a pachinko ball discharged from the rear side of a pachinko machine or the like installed on a pachinko machine stand, and the pachinko balls received by the ball receiving portion are rolled in a row to form the pachinko island stand. It is related with the pachinko ball collection device which consists of a ball discharge part discharged to a predetermined collection basket inside.

  As is well known, a pachinko ball collecting device that collects pachinko balls discharged from the back side of the pachinko machine is provided below the back side of the pachinko machine. The ball receiving portion to be received and the pachinko balls received are rolled in a row toward the pachinko ball dropping port formed on the downstream side, and then finally guided to the ball counter substantially vertically from the pachinko ball dropping port. And a ball discharger for discharging pachinko balls one by one to an out-ball collection basket which is a predetermined collection basket. In such a pachinko ball collection device, the pachinko balls arranged in a line at the ball discharge section are guided almost directly below the pachinko ball drop opening to the ball counter, but in conventional models, in the vicinity of the pachinko ball drop opening In some places, such as ball counters and ball counters, clogging may occur.

  However, for example, in the pachinko ball collecting apparatus disclosed in Patent Document 1, even if the above-described problem occurs, it does not become a big problem. In the case of the pachinko ball recovery device disclosed in Patent Document 1, as in other conventional models, the pachinko balls are aligned in a line on the upstream side of the ball discharge portion and then guided to the downstream side of the ball discharge portion. However, unlike other conventional models, the distance that the pachinko balls roll in a single row is short, so even if the pachinko ball is just below the pachinko ball drop opening of the ball discharge part or just before the pachinko ball Pachinko balls that are generated when aligning pachinko balls in a row because pachinko balls are aligned in a row at a position close to the location where the balls are jammed, even if they may be clogged when passing through a counter, etc. This is because impacts, vibrations, and the like due to collision between balls easily propagate to a clogged location, and clogging is easily eliminated by the propagated impacts, vibrations, and the like.

  From this, the clogging in the vicinity of the pachinko ball drop opening and the ball counter in the conventional models other than Patent Document 1 is the distance that the pachinko balls roll in one row in the ball discharge section (hereinafter, one row rolling). It turned out that the problem could be solved by shortening the distance. However, this fact is a constraint clause in designing a pachinko ball collection device that “the one-row rolling distance in the ball discharge section must be designed to be short”. The result was deprivation of freedom of conception.

Therefore, in view of the above circumstances, the present applicant has studied and examined whether or not “the same effect as in Patent Document 1 can be obtained even if the one-row rolling distance in the ball discharge portion is designed to be long”. Went.
As a result of this research and examination, the present applicant applied the features of the pachinko ball collecting device disclosed in Patent Document 1 and devised an improved version of this pachinko ball collecting device. Specifically, the length of the ball discharge portion of the pachinko ball recovery device disclosed in Patent Document 1 is long and the bottom surface has a steep slope (for example, about 8 °).

By configuring in this way, that is, by forming the bottom surface of the ball discharge portion steeply, the speed at which the pachinko balls flow down the ball discharge portion increases, and the impact force when the pachinko balls collide also increases. Even if the one-row rolling distance in the ball discharge portion is designed to be long, the same effect as in Patent Document 1, that is, even if a ball clogging occurs on the downstream side of the ball discharge portion, When the pachinko balls flowing down the gradient collide with the pachinko balls that are causing clogging, a large impact force was generated, and the clogging was eliminated by this large impact force and vibration.

  However, the above-described pachinko ball collecting apparatus has the following problems.

  As mentioned above, the method of increasing the speed of the pachinko balls that flow down the ball discharge section by making the bottom surface of the ball discharge section steep is the ball generated in the vicinity of the pachinko ball drop opening or a ball counter. It is effective for relieving clogging, but the speed of the pachinko balls that flow down the ball discharge part becomes too fast, so if there is no ball clogging, the place where the pachinko balls are directly below the ball discharge part, that is, There is a problem that the pachinko balls are irregularly jumped up at the pachinko ball drop opening, and the pachinko balls cannot be discharged smoothly from the ball discharge section.

  Therefore, the present invention has been made in view of the above-described circumstances, and the object of the present invention is the downstream side of the ball discharge portion even if the ball discharge portion has a long distance for rolling pachinko balls in a row. It is an object of the present invention to provide a pachinko ball collecting apparatus that can eliminate clogging of balls and can smoothly discharge pachinko balls from the ball discharge section.

In the pachinko ball collecting device 5, the pachinko balls received by the ball receiving portion 10 are rolled in a row and discharged to a predetermined collecting basket in the pachinko island platform 1, The bottom surface portion 17 constituting the bottom portion of the ball discharge portion 11 is formed as a gentle slope section 19 having a gentle slope on the downstream side, and sections other than the slow slope section 19 are more than the gentle slope section 19. The pachinko ball collecting device 5 is characterized in that it is formed as a steep slope section 18 having a steep slope.

  Moreover, in the invention which concerns on Claim 2, when it demonstrates with reference to drawings, as shown in FIG. 18, the said pachinko ball collection | recovery apparatus 5 described in Claim 1 WHEREIN: The said gentle gradient area 19 is a pachinko ball. The pachinko ball collecting device is characterized by being formed with a length of 5 to 6 times the diameter of the pachinko ball from the center of the pachinko ball dropping port 57 to be dropped substantially vertically toward the upstream side.

  Moreover, in the invention which concerns on Claim 3, when it demonstrates with reference to drawings, as shown in FIG. 15, the said pachinko ball collection | recovery apparatus described in Claim 1 or Claim 2 is as follows. The outer peripheral wall 15 is formed in a cylindrical shape, and the ball receiving portion 10 and the ball discharging portion 11 are arranged so that the pachinko balls received by the ball receiving portion 10 are guided to the ball discharging portion 11. The pachinko ball 1 communicates over a predetermined length on the upstream side of the portion 11, and the lowermost portion 13 of the inclined bottom surface 12 constituting the bottom portion of the ball receiving portion 10 is downstream from the upstream end portion 46 of the ball discharge portion 11. It arrange | positions so that it may become in the range of a piece, it rolls the pachinko ball on the said inclined bottom face 12 toward the position where the said lowest part 13 is arrange | positioned, and it is downstream from the upstream end part 46 of the said ball | bowl discharge | emission part 11 Patin characterized by being guided in a line Was a ball collecting device 5.

  Moreover, in the invention which concerns on Claim 4, when it demonstrates with reference to drawings, as shown in FIG. 15, the said pachinko ball collection | recovery apparatus described in Claim 3 is a predetermined area of the upstream of the said ball discharge part 11. As shown in FIG. The pachinko ball collecting device 5 is characterized in that it is placed in contact with the outer peripheral wall 15 constituting the outer periphery of the ball receiving portion 10.

  Moreover, in the invention which concerns on Claim 5, when it demonstrates with reference to drawings, as shown in FIG. 2, the said pachinko ball collection | recovery apparatus described in Claim 4 is the upstream end part 46 of the said ball discharge part 11, and The pachinko ball collecting apparatus 5 is characterized in that a step 14 is provided between the inclined bottom surface 12.

  Moreover, in the invention which concerns on Claim 6, when it demonstrates with reference to drawings, as shown in FIG. 23 thru | or FIG. 27, the said pachinko ball collection | recovery apparatus described in Claim 3 thru | or 5 is the said ball receiving part. The outer periphery of 10 cylindrical outer peripheral walls 15 is configured by concentrically stacking a first cover member 101, a second cover member 102, and a third cover member 103 which are a plurality of cylindrical members having different diameters. In addition, the pachinko ball collecting apparatus 5 is characterized in that an expansion / contraction cover 100 that expands and contracts stepwise in the central axis direction is provided concentrically with the ball receiving portion 10.

  In the invention according to claim 1, the bottom surface portion 17 of the ball discharge portion 11 is formed as a gentle slope section 19 having a gentle slope on the downstream side, and a section other than the slow slope section 19 is the slow slope. A steep slope section 18 having a steeper slope than the slope section 19 is formed. For this reason, when the ball clogging has occurred on the downstream side of the ball discharge unit 11, the pachinko ball flowing down at a high speed in the steep slope section 18 of the ball discharge unit 11 collides with the pachinko ball causing the ball clogging. The clogging can be eliminated by the shock and vibration. As described above, when a ball clogging occurs in the ball counter 39, more specifically, a ball counter 39 to be described later, the pachinko ball stagnates in the gentle gradient section 19 due to the ball clogging. In other words, there is substantially no gentle slope section 19 and the speed of the pachinko balls flowing down the steep slope section 18 is not slowed down so much that it collides with a pachinko ball that is clogged with balls. It becomes easy to eliminate clogging. On the other hand, when no clogging occurs at the downstream side of the ball discharge section 11, there is no pachinko ball in the gentle gradient section 19, and the pachinko balls that have flowed down the steep slope section 18 The flow speed is reduced by this, and the phenomenon that the pachinko ball jumps irregularly at the place where the pachinko ball is directly dropped from the ball discharge portion 11 does not occur, and the pachinko ball can be discharged smoothly from the ball discharge portion 11. it can.

  From the above, even if the ball discharge part where the pachinko balls roll in a row is long, clogging on the downstream side of the ball discharge part can be eliminated and at the same time the pachinko balls are discharged. It can be discharged smoothly from the section.

  In the invention which concerns on Claim 2, the gentle gradient area 19 is formed in the length of 5-6 times the diameter of a pachinko ball toward the upstream from the center of the pachinko ball dropping port 57 which drops a pachinko ball. . As a result, when ball clogging occurs on the downstream side of the ball discharge unit 11, up to about 5 to 6 pachinko balls are stagnated in the gentle gradient section 19, and the gentle gradient section 19 is shortened to an appropriate distance. Therefore, the pachinko ball that has flowed down the steep slope section 18 can collide with the stagnant pachinko ball with an appropriate impact force without decelerating. On the other hand, when there is no clogging of the ball on the downstream side of the ball discharge unit 11, the speed of the pachinko balls flowing down the steep slope section 18 can be sufficiently reduced. The pachinko balls can be smoothly discharged from the ball discharge portion 11 without causing a phenomenon such as irregularly jumping up of the pachinko balls at a position directly below the ball.

  From the above, even if the ball discharge part where the pachinko balls roll in a row is long, clogging on the downstream side of the ball discharge part can be eliminated and at the same time the pachinko balls are discharged. It can be discharged smoothly from the section.

  In the invention according to claim 3, the ball receiving portion 10 and the ball discharge portion 11 in which the outer peripheral wall 15 is formed in a cylindrical shape communicate with each other over a predetermined length on the upstream side of the ball discharge portion 11. The lowermost portion 13 of the inclined bottom surface 12 constituting the bottom portion of the portion 10 is disposed so as to be within the range of one pachinko ball downstream from the upstream end portion 46 of the ball discharge portion 11. Thereby, when the pachinko balls received by the ball receiving portion 10 are guided to the ball discharge portion 11, when the amount of the pachinko balls in the ball receiving portion 10 is small, as shown in FIG. After rolling toward the upstream side of the ball discharging unit 11, the ball discharging unit 11 rolls while being aligned in a line from the upstream side to the downstream side of the ball discharging unit 11. On the other hand, when the amount of pachinko balls in the ball receiver 10 is large, as shown in FIG. 20B, the pachinko balls on the inclined bottom surface 12 on the ball discharger 11 side have already rolled the ball discharger 11. The ball discharger 11 is guided so as to cover the pachinko ball from above, and rolls the ball discharger 11 while being aligned with the pachinko ball in the ball discharger 11 in a line.

  From the above, even if the amount of pachinko balls received by the ball receiving portion 10 is large, the pachinko balls are smoothly guided from the ball receiving portion 10 to the ball discharging portion 11 and the pachinko balls are smoothly discharged from the ball discharging portion 11. Can be discharged to an out-ball collection basket 6 which is a predetermined collection basket.

  In the invention according to claim 4, the predetermined section on the upstream side of the ball discharge portion 11 is arranged in contact with the outer peripheral wall 15 constituting the outer periphery of the ball receiving portion 10. Thereby, the predetermined area of the upstream of the ball discharge part 11 is comprised integrally with the ball receiving part 10, and the ball receiving part 10 can be formed in a cylindrical shape as a whole. Therefore, a cylindrical shape in which the range for receiving the pachinko ball does not change even when the ball receiving portion 10 and the ball discharging portion 11 are integrated, even when the ball receiving portion 10 is rotated about its center as a rotation axis. The pachinko ball collecting device 5 can be used with the features of the pachinko ball collecting device 5 and the design of the pachinko ball collecting device 5 can be improved.

  In the invention which concerns on Claim 5, since the level | step difference 14 is provided between the upstream edge part 46 of the ball discharge part 11, and the inclined bottom face 12 of the ball receiving part 10, from the ball receiving part 10 to the ball discharge part 11 When the pachinko balls are guided, the pachinko balls fall from the ball receiver 10 to the ball discharger 11, so that the pachinko balls can be more smoothly guided from the ball receiver 10 to the ball discharger 11. .

  In the invention according to claim 6, on the outer periphery of the cylindrical outer peripheral wall 15 of the ball receiving portion 10, an expansion / contraction cover 100 that expands and contracts stepwise in the central axis direction is provided concentrically with the ball receiving portion 10. ing. Thereby, even if it is a case where a space | interval arises between the ball receiving part 10 and the out ball | bowl discharge port 3 in the rear surface of the pachinko machine 2 by the state which attached the pachinko ball collection | recovery apparatus 5, the expansion / contraction cover 100 is removed from the ball. By extending toward the discharge port 3 and narrowing the interval, the out ball discharged from the out ball discharge port 3 can be reliably received by the ball receiving portion 10, and balls other than the out ball can be received by the ball receiving portion 10. Jumping in can be prevented.

In the following description, the front side of the pachinko machine 1 will be described as the front side, and the rear side of the pachinko machine 1 will be described as the rear side.

  As is well known, the pachinko island platform 1 is structured in a rectangular parallelepiped shape, and a plurality of pachinko machines 2 are arranged in the back direction on both longitudinal sides thereof, but in FIG. Only a part is shown. As shown in FIG. 1, the pachinko machine 2 installed on the pachinko machine platform 1 receives a pachinko ball used in the pachinko machine 2 and discharged from the out ball outlet 3 at the lower position on the rear side. A pachinko ball collecting device 5 for sending the pachinko balls to the out ball collecting basket 6 (see FIG. 14) in the pachinko island stand 1 is installed. The pachinko ball collecting device 5 is attached to the pachinko island base 1 by a mounting base 4 described later. A pachinko ball discharged from the rear side of the pachinko machine 2, that is, a pachinko ball discharged from the out ball discharge port 3, is commonly referred to as an “out ball”.

  Next, the pachinko ball collection device 5 constituting the main part of the present invention will be described with reference to the drawings. As shown in FIG. 2, the pachinko ball collecting device 5 mainly includes a cylindrical ball receiving portion 10 that receives a pachinko ball discharged from the rear side of the pachinko machine installed on the pachinko island platform 1, and this ball receiving portion. The ball discharging unit 11 is configured to roll the pachinko balls received in 10 in a row and discharge them to an out ball collecting basket 6 which is a predetermined collecting basket in the pachinko island platform 1. The ball receiving portion 10 and the ball discharging portion 11 communicate with each other over a predetermined length upstream of the ball discharging portion 11 so that the pachinko balls received by the ball receiving portion 10 are guided to the ball discharging portion 11. doing. Specifically, as shown in FIG. 15, the left side 70 of the ball discharge unit 11 formed in a bowl shape communicates with the range of the length indicated by L, while the right side 71 of the ball discharge unit 11. Is inscribed with the outer peripheral wall 15 of the ball receiving portion 10, and the upstream side of the ball discharge portion 11 and the ball receiving portion 10 are arranged inscribed in a predetermined section so as to be integrated with each other. If only the shape is viewed, it is formed in a substantially circular shape in plan view. 2, the upstream side of the ball discharge portion 11 formed integrally with the ball receiving portion 10 is formed at a position lower than the inclined bottom surface 12 constituting the bottom portion of the ball receiving portion 10. Therefore, the pachinko balls fall from the inclined bottom surface 12 toward the ball discharge portion 11.

  Here, the ball receiver 10 will be described with reference to FIG. 2. The ball receiver 10 is formed in a cylindrical shape as described above, and its bottom is formed as an inclined bottom surface 12. A low resilience member 47 is affixed to the surface of the inclined bottom surface 12 so that the pachinko balls received by the ball receiving portion 10 bounce greatly and do not jump out of the ball receiving portion 10. Further, the outer periphery of the ball receiving portion 10 is formed by an outer peripheral wall 15, and the upstream side of the above-described ball discharge portion 11 is arranged inscribed in the outer peripheral wall 15 as shown in FIG. 15 over a predetermined section. Has been. Thus, since the predetermined section on the upstream side of the ball discharge portion 11 is arranged inscribed in the outer peripheral wall 15, a part of the upstream side of the ball discharge portion 11 is configured integrally with the ball receiving portion 10, The ball receiver 10 can be formed in a cylindrical shape as a whole.

  Thereby, while the ball receiving portion 10 and the ball discharging portion 11 are integrated, a cylindrical shape in which the range for receiving the pachinko ball does not change even when the ball receiving portion 10 is rotated about its center as a rotation axis. The pachinko ball collecting device 5 can be used with the features of the pachinko ball collecting device 5 and the design of the pachinko ball collecting device 5 can be improved.

  The outer peripheral wall 15 is partly cut out and formed as a communication port 48 for projecting the downstream side of the ball discharge unit 11 to the outside. This communication port 48 is described later of the ball discharge unit 11. The bottom surface portion 17 to be inserted is inserted. Further, in the vicinity of the upper end portion of the outer peripheral wall 15, mounting projections 16 for mounting the expansion / contraction cover 100 described later are provided at two locations facing each other.

  By the way, the inclined bottom surface 12 described above is formed so as to be inclined downward toward the upstream side of the ball discharge portion 11, and the lowermost portion 13 which is the downstream end thereof is as shown in FIGS. The ball discharge portion 11 is positioned so as to be within the range of one pachinko ball downstream from the upstream end portion 46.

  Thereby, when the pachinko balls received by the ball receiving portion 10 are guided to the ball discharge portion 11, when the amount of the pachinko balls in the ball receiving portion 10 is small, as shown in FIG. After rolling toward the upstream side of the ball discharging unit 11, the ball discharging unit 11 smoothly rolls toward the downstream side while being aligned in a line from the upstream side to the downstream side of the ball discharging unit 11. Go. On the other hand, when the amount of pachinko balls in the ball receiver 10 is large, as shown in FIG. 20B, the pachinko balls on the inclined bottom surface 12 on the ball discharger 11 side have already rolled the ball discharger 11. The pachinko balls 11 are guided from above the pachinko balls, and are smoothly rolled toward the downstream side of the ball discharge portions 11 while being aligned with the pachinko balls in the ball discharge portions 11 in a line. From the above, even if the amount of pachinko balls received by the ball receiving portion 10 is large, the pachinko balls are smoothly guided from the ball receiving portion 10 to the ball discharging portion 11 and the pachinko balls are smoothly discharged from the ball discharging portion 11. Can be discharged to an out-ball collection basket 6 which is a predetermined collection basket.

  In addition, when the lowest part 13 of the inclined bottom surface 12 of the ball receiving part 10 is located downstream from the range of one pachinko ball downstream from the upstream end part 46 of the ball discharge part 11, for example, FIG. The pachinko ball in the ball receiver 10 rolls toward the lowermost portion 13 of the inclined bottom surface 12 located on the CC line, and the lowermost portion 13 is located on the CC line. After the pachinko ball is guided to the ball, the ball discharger 11 is rolled. In this way, the pachinko balls guided to the lowermost part 13 roll on the ball discharge portion 11 as they are, but at this time, the pachinko balls guided upstream from the line CC in the ball discharge portion 11. Is blocked by the pachinko ball that is guided to the lowermost part 13 and rolls around the ball discharge part 11, and stagnates on the upstream side of the CC line in the ball discharge part 11. Then, the pachinko balls that follow are blocked by the stagnant pachinko balls, and the stagnant pachinko balls are further increased, and the flow of the entire pachinko balls that are finally guided to the ball discharge section 11 is stagnated. The clogging will occur in the part 10.

  Further, as shown in FIGS. 2 and 6, a bottom surface member 29 for attaching a slide base 60 to be described later to the ball receiver 10 is attached to the back surface side of the ball receiver 10. The bottom surface member 29 is formed in a substantially disk shape so as to coincide with the shape of the back surface side of the ball receiving portion 10, and a mounting portion 25 (see FIG. The mounting insertion portion 30 to be inserted is projected. On the outer peripheral surface of the attachment insertion portion 30, an engagement uneven portion 31 that engages with an engagement piece 26 (see FIG. 3) described later of the ball receiving portion 10 is formed. In addition, an insertion hole 32 into which an attachment member 33 for attaching the bottom surface member 29 to the ball receiver 10 is inserted is formed in the center of the bottom surface member 29.

  Further, the mounting portion 25 is formed on the back surface side of the ball receiving portion 10 as described above, and this mounting portion 25 protrudes in a cylindrical shape substantially at the center of the inclined bottom surface 12 as shown in FIG. In the vicinity of the end portion on the inner surface side, the above-mentioned engagement pieces 26 are provided at two positions so as to face each other. Further, a mounting boss 27 having a mounting screw hole 28 for mounting the bottom member 29 to the ball receiving portion 10 is projected from the inside of the mounting portion 25 and substantially at the center of the inclined bottom surface 12.

  Thus, as shown in FIG. 2, in order to attach the bottom member 29 to the back side of the ball receiver 10, the mounting protrusion 34 protruding from the mounting member 33 is inserted into the insertion hole 32 of the bottom member 29. Thus, the bottom surface member 29 is brought into contact with the back surface of the ball receiver 10. At this time, the mounting boss 27 is inserted into the boss insertion hole 35 formed in the mounting convex portion 34. Then, the mounting screw 36 inserted into the boss insertion hole 35 from below the mounting member 33 is screwed into the mounting screw hole 28 of the mounting boss 27, so that the bottom surface member 29 becomes the ball receiving portion 10 as shown in FIG. It is attached to the back side. As a result, the bottom member 29 is rotatably attached to the ball receiver 10. At this time, the engaging piece 26 engages with the concave portion of the engaging concave-convex portion 31. Fixed against. However, since the wall surface of the mounting portion 25 bends outward, when the bottom member 29 is rotated with respect to the ball receiving portion 10, the engaging piece 26 rides on the convex portion of the engaging uneven portion 31. Therefore, the bottom surface member 29 can be rotated with respect to the ball receiving portion 10 while being fixed at a position where the concave portion of the engaging uneven portion 31 and the engaging piece 26 are engaged with each other. The plurality of substantially hemispherical protrusions formed on the upper surface of the disk below the mounting member 33 and in contact with the back surface side of the bottom surface member 29 are friction generated when the mounting member 33 and the bottom surface member 29 slide. It is provided to reduce this.

  Next, the ball discharge portion 11 will be described. In FIG. 2, the ball discharge portion 11 is formed integrally with the ball receiving portion 10 in a predetermined manner on the upstream side, as described above. Further, on the downstream side outside the predetermined section, the side surface is formed as the side wall 20 and the bottom portion is formed as the bottom surface portion 17, and the pachinko ball is dropped substantially vertically on the downstream end of the bottom surface portion 17. A pachinko ball dropping port 57 (see FIG. 18) is formed. Further, as shown in FIGS. 18 and 19, the bottom surface portion 17 is formed as a gentle slope section 19 having a gentle slope on the downstream side, and sections other than the slow slope section 19 are gentle slope sections. A steep slope section 18 having a steeper slope than 19 is formed.

  For this reason, when the ball clogging has occurred on the downstream side of the ball discharge unit 11, the pachinko ball flowing down at a high speed in the steep slope section 18 of the ball discharge unit 11 collides with the pachinko ball causing the ball clogging. The clogging can be eliminated by the shock and vibration. As described above, when a ball clogging occurs in the ball counter 39, more specifically, a ball counter 39 to be described later, the pachinko ball stagnates in the gentle gradient section 19 due to the ball clogging. In other words, there is substantially no gentle slope section 19 and the speed of the pachinko balls flowing down the steep slope section 18 is not slowed down so much that it collides with a pachinko ball that is clogged with balls. It becomes easy to eliminate clogging. On the other hand, when no clogging occurs at the downstream side of the ball discharge section 11, there is no pachinko ball in the gentle gradient section 19, and the pachinko balls that have flowed down the steep slope section 18 The flow speed is reduced by this, and the phenomenon that the pachinko ball jumps irregularly at the place where the pachinko ball is directly dropped from the ball discharge portion 11 does not occur, and the pachinko ball can be discharged smoothly from the ball discharge portion 11. it can.

  From the above, even if the ball discharge part where the pachinko balls roll in a row is long, clogging on the downstream side of the ball discharge part can be eliminated and at the same time the pachinko balls are discharged. It can be discharged smoothly from the section.

  In the present embodiment, the gentle gradient section 19 is formed with a length of 5 to 6 times the diameter of the pachinko ball (indicated by P in FIG. 18) from the center of the pachinko ball drop opening 57 toward the upstream side. ing. As a result, when ball clogging occurs on the downstream side of the ball discharge unit 11, up to about 5 to 6 pachinko balls are stagnated in the gentle gradient section 19, and the gentle gradient section 19 is shortened to an appropriate distance. Therefore, the pachinko ball that has flowed down the steep slope section 18 can collide with the stagnant pachinko ball with an appropriate impact force without decelerating. On the other hand, when there is no clogging of the ball on the downstream side of the ball discharge unit 11, the speed of the pachinko balls flowing down the steep slope section 18 can be sufficiently reduced. The pachinko balls can be smoothly discharged from the ball discharge portion 11 without causing a phenomenon such as irregularly jumping up of the pachinko balls at a position directly below the ball.

  From the above, even if the ball discharge part where the pachinko balls roll in a row is long, clogging on the downstream side of the ball discharge part can be eliminated and at the same time the pachinko balls are discharged. It can be discharged smoothly from the section.

Further, a step 14 is formed between the upstream end portion 46 of the bottom surface portion 17 and the inclined bottom surface 12 of the ball receiving portion 10.
As described above, since the step 14 is formed, the pachinko balls are dropped from the ball receiving portion 10 to the ball discharging portion 11 when the pachinko balls are guided from the ball receiving portion 10 to the ball discharging portion 11. Therefore, the pachinko balls can be more smoothly guided from the ball receiver 10 to the ball discharger 11.

  Further, a position on the downstream side of the ball discharging unit 11 and substantially corresponding to the above-described gentle gradient section 19 is a member mounting for mounting a ball counter 39 for detecting a pachinko ball discharged from the pachinko ball collecting device 5 A portion 49 is formed. As shown in FIG. 2, an attachment member 37 into which a ball counter 39 is inserted is attached to the member attachment portion 49 by means of an attachment screw 38, whereby the ball counter 39 is attached to the pachinko ball collecting device 5. It will be. A ball passage hole 40 through which the pachinko ball passes is formed on the rear surface side of the ball counter 39 so as to correspond to the pachinko ball drop opening 57.

  Next, a front / rear slide mechanism for sliding the pachinko ball collecting device 5 in the front-rear direction with respect to the pachinko machine 2 and a left / right slide mechanism for sliding the pachinko machine 2 in the left-right direction. explain. That is, the pachinko ball collecting apparatus 5 according to the present embodiment includes an attachment portion 4 installed substantially parallel to the left-right direction of the pachinko machine 2 and a main body base 50 for attaching the pachinko ball collection device 5 to the attachment portion 4. The front / rear slide mechanism for sliding the pachinko ball collecting device 5 in the front-rear direction with respect to the main body base 50 and the main body base 50 with the pachinko ball collecting device 5 attached to the mounting portion 4 are slid in the left-right direction. A left-right slide mechanism.

  Thus, the front and rear slide mechanism mainly includes first slide portions 51a and 51b described later formed on the upper side of the main body base 50, and a second slide portion 42 described later formed on the back side of the ball receiving portion 10. And a slide guide part 61 that is formed on a slide base 60 (described later) that slides in the front-rear direction relative to the main body base 50 and the ball receiving part 10 and that engages both the first slide parts 51a, 51b and the second slide part 42. And movement restricting portions 64a and 64b, which will be described later, which are formed at both ends of the slide guide portion 61 in the front-rear direction and restrict the slide movement of the slide base 60 with respect to the main body base 50 and the slide movement of the ball receiving portion 10 with respect to the slide base 60, Details will be described below. The left / right slide mechanism will be described after the description of the front / rear slide mechanism.

  First, as shown in FIG. 5, the main body base 50 installed on the pachinko island base 1 side is formed in a substantially U shape in a longitudinal sectional view. A slide base installation portion 58 on which the slide base 60 is installed is formed, and a sliding projection 54 that slides on a sliding convex portion 83 of a sliding guide plate 82 (described later) extends in the longitudinal direction on the inner side surface. Projecting in two places. In addition, positioning holes 55 are formed on both sides of the upper surface in the longitudinal direction for attaching and positioning the main body base 50 to a mounting base 80 described later.

  First slide portions 51 a and 51 b that engage with the slide guide portion 61 of the slide base 60 protrude from both sides of the slide base installation portion 58. The first slide portions 51a and 51b are formed in a triangular cross-section in which the projecting dimension gradually increases from the bottom to the top. The first slide portion 51a is located on the front surface side and is located on the rear surface side. What is located is the first slide portion 51b.

  Further, on the lower surface of the slide base installation portion 58, there are two rows of second engagement grooves 52 that are engaged with second engagement protrusions 65 (see FIG. 7), which will be described later, formed on the back surface side of the slide base 60. Is formed. The second engagement groove 52 is formed in an uneven shape in the sliding direction (front-rear direction) on the upper surface of the main body base 50, and the second engagement protrusion 65 is engaged with the recess 53. Yes. The second engagement protrusion 65 and the second engagement groove 52 achieve a slide base holding function for holding the slide movement in the front-rear direction performed by the main body base 50 and the slide base 60 at the slide position. .

  Next, as shown in FIG. 5, the slide base 60 is formed in a substantially rectangular and flat plate shape, and a member for attaching an attachment / detachment regulating member 66 to be described later to the end located on the front side thereof. A mounting portion 68 is formed. Further, on both side surfaces of the slide base 60, slide guide portions 61 are formed in which the first slide portions 51a and 51b and the second slide portion 42 are engaged. The slide guide portion 61 is formed in a V-shaped cross section that gradually increases in depth toward the center.

  The end portion of the slide guide portion 61 is formed at a position spaced from the end portion of the slide base 60 on both the front side and the rear side. The end portion on the rear surface side of the slide guide portion 61 is formed as a movement restricting portion 64a for restricting the limit of the rearward slide movement by the first slide portion 51b and the second slide portion 42 coming into contact with each other. When the attachment / detachment restriction member 66 is attached to the portion 68, the first slide portion 51a and the second slide portion 42 are in contact with the rear surface side end portion of the attachment / detachment restriction member 66 in the same manner as the movement restriction portion 64a. It will function as a movement restricting section 64b that restricts the limit of movement.

  A first engagement groove 62 is formed on the rear surface side of the center of the upper surface of the slide base 60 and engages with a first engagement protrusion 41 (see FIG. 6), which will be described later, formed on the back surface side of the bottom member 29. ing. The first engagement groove 62 is formed in an uneven shape in the sliding direction, and the first engagement protrusion 41 is engaged with the recess 63. The first engagement protrusion 41 and the first engagement groove 62 achieve a ball receiving portion holding mechanism that holds the slide movement in the front-rear direction performed by the ball receiving portion 10 and the slide base 60 at the slide position. Is done.

  Accordingly, as shown in FIG. 7, a second engagement protrusion 65 that engages with the concave portion 53 of the second engagement groove 52 described above is provided on the rear surface side of the slide base 60. The second engagement protrusion 65 moves up and down as the root portion bends.

  Next, as shown in FIG. 6, the bottom member 29 attached to the ball receiver 10 is formed with a slide base installation portion 69 in which the slide base 60 is installed in the front-rear direction at substantially the center of the back surface side. ing. On both sides of the rear surface side of the slide base installation portion 69, a second slide portion 42 that engages with the slide guide portion 61 of the slide base 60 protrudes. The second slide part 42 is formed in a triangular cross section in which the projecting dimension gradually increases from below to above. Further, a first engagement protrusion 41 that engages with the concave portion 63 of the first engagement groove 62 described above protrudes from the rear surface side end portion of the slide base installation portion 69.

  In order to assemble the ball receiver 10, the main body base 50 and the slide base 60, first, as shown in FIGS. 5 and 8, the slide base 60 is first inserted from the rear surface side of the slide base installation portion 58 of the main body base 50. The first slide portions 51 a and 51 b are engaged with the slide guide portion 61 of the slide base 60 by installing the slide guide 60 in such a manner. Next, similarly, the second slide part 42 is engaged with the slide guide part 61 of the slide base 60 by installing the slide base 60 so as to be inserted from the rear surface side of the slide base installation part 69 of the bottom member 29. In this state, the attachment / removal restricting member 66 is attached to the member attaching portion 68 of the slide base 60 with the attachment screw 67, so that the main body base 50 and the slide base 60 are pachinko ball collecting devices as shown in FIGS. 5 (ball receiver 10). FIG. 9 shows a reference position in which the centers of the ball receiver 10, the main body base 50, and the slide base 60 are aligned with each other in the sliding direction.

  As shown in FIG. 10 (A), the front and rear slide mechanism of the pachinko ball collecting device 5 assembled as described above slides the slide guide portion 61 along the first slide portions 51a and 51b. The slide base 60 can be slid from the reference position toward the front side until the first slide part 51b and the movement restricting part 64a come into contact with each other on the main body base 50. Further, as shown in FIG. 10B, the second slide portion 42 is slid along the slide guide portion 61, so that the second slide portion 42 and the second slide portion 42 are moved on the slide base 60 from the reference position toward the front surface side. The pachinko ball collecting device 5 can be slid and moved until the movement restricting portion 64b comes into contact.

That is, since the ball receiving portion 10 slides in two steps toward the front side with respect to the main body base 50, the ball receiving portion 10 is moved to the front side even if the longitudinal dimension of the front / rear slide mechanism is kept small. It can be moved sufficiently toward. In addition, by suppressing the longitudinal dimension of the front / rear slide mechanism, the front / rear slide mechanism can be easily hidden from the back side of the ball receiver 10 when viewed from above in the reference position state. Since it does not protrude from the area on the back side of the portion 10, when the entire pachinko ball collecting device 5 provided with the front / rear slide mechanism is viewed, the design characteristic (ball receiving portion 10) originally possessed by the pachinko ball collecting device 5 Does not impair the excellent design of the cylindrical shape.
In other words, even if the ball receiver 10 is formed small, the front and rear slide mechanism that can ensure a sufficient slide movement distance of the ball receiver 10 without impairing the design of the pachinko ball collection device 5 is a pachinko ball. The recovery device 5 can be provided.

  As described above, when the slide base 60 slides on the main body base 50 toward the front side, the end portion on the rear surface side of the first slide portion 51b is moved to the movement restricting portion 64a (in FIG. 9 to FIG. Therefore, the slide base 60 does not move to the front side from this position. Further, when the ball receiving portion 10 slides on the slide base 60 toward the front side as described above, the end portion on the front side of the second slide portion 42 is moved to the movement restricting portion 64b (a in FIG. 9 to FIG. 11). The ball receiver 10 does not move to the front side of this position.

  In addition, the second slide portion 42 is disposed so that the end portion thereof is in contact with the rear side movement restricting portion 64a in the state of the reference position, and the slide base 60 is, as shown in FIG. Is slid along the first slide portions 51a and 51b, and slides on the main body base 50 from the reference position toward the rear surface side until the front-side movement restricting portion 64b contacts the first slide portion 51a. It becomes movable. At this time, the front end of the first slide portion 51a abuts against the movement restricting portion 64b, and the front end of the second slide portion 42 abuts against the movement restricting portion 64a. And the ball receiving part 10 does not move to the rear side from this position.

  Accordingly, as shown in FIG. 14, since the ball receiver 10 slides toward the rear surface with respect to the main body base 50, for example, when the pachinko machine 2 is replaced with a new base, the ball receiver 10 interferes. Therefore, there will be no hindrance to the replacement work. Further, the slide movement toward the rear side is a one-step slide movement unlike the slide movement toward the front side of the pachinko machine 2, and as shown in FIG. Without sliding, it is possible to prevent interference with the ball receiver 10 of the pachinko ball collecting device 5 installed on the facing side. Furthermore, this one-step sliding movement to the rear side that does not slide more than necessary is particularly when, for example, a bill conveyance rail, a prepaid card collection rail, etc. are installed at the center and above the out ball collection basket 6. It is effective for.

  Further, as described above, when the slide base 60 slides on the main body base 50, the second engagement protrusion 65 moves while moving up and down along the unevenness of the second engagement groove 52. Then, when the second engagement protrusion 65 is engaged with the recess 53 formed in the second engagement groove 52, the position of the slide base 60 with respect to the main body base 50 is set to a required position, that is, the recess 53 is connected to the second engagement groove 52. The joint 65 is held at the engaged position. Similarly, when the ball receiver 10 slides on the slide base 60, the first engagement protrusion 41 moves while moving up and down along the unevenness of the first engagement groove 62. Then, when the first engagement protrusion 41 engages with the recess 63 formed in the first engagement groove 62, the position of the ball receiving portion 10 with respect to the slide base 60 is set to the required position, ie, the recess 63. The engagement protrusion 41 is held at the engaged position. Thereby, since the ball receiving part 10 is hold | maintained with respect to the main body base 50, the ball receiving part 10 can be hold | maintained in the state moved to the required position.

  As described above, the pachinko ball collecting device 5 is configured to be movable in the front-rear direction of the pachinko machine 2 by the front-rear slide mechanism, but with respect to the mounting base 4 provided on the pachinko island base 1 by the left-right slide mechanism. The pachinko machine 2 can also move in the left-right direction. Then, next, the structure of this right-and-left slide mechanism is demonstrated.

  Therefore, the left and right slide mechanism mainly includes a main body base 50 in which a side view and a vertical cross-sectional view are formed in a substantially U shape, and the pachinko ball collecting device 5 is installed on the upper side. The main body base 50 includes a substantially flat sliding guide plate 82 that fits in a letter shape and covers the upper surface portion of the mounting portion 4 that slides on the upper surface portion. The details will be described below.

  As shown in FIG. 1, the mounting base 4 is formed in a box shape that is long in the left-right direction of the pachinko machine 2. As shown in FIG. 12, the mounting base 4 is mainly attached directly to the pachinko island base 1. The base 80 includes a sliding guide plate 82 on which the pachinko ball collecting device 5 moves.

  The mounting base 80 is formed in a box shape having an upper opening, and a sliding groove 81 in which a fixing member 90 described later slides is formed in the longitudinal direction. The sliding guide plate 82 is formed in a substantially flat plate shape, and an insertion groove 84 through which a positioning screw 56 (described later) is inserted is formed in the center of the sliding guide plate 82. When the main body base 50 provided with the pachinko ball collecting device 5 is brought into contact with both sides of the groove 84 and on the upper surface of the sliding guide plate 82, the sliding protrusion 54 on the inner side of the main body base 50 comes into contact. A moving projection 83 is formed over the longitudinal direction.

  Further, as described above, the fixing member 90 can slide in the sliding groove 81 of the mounting base 80. The fixing member 90 is formed in a hexagonal column shape, and its shaft A fixing screw hole 91 into which the positioning screw 56 is screwed is formed at the center, and the side wall thereof is formed as a sliding surface 92 that abuts against the side wall of the sliding groove 81.

  In order to assemble the mounting base 4 and attach the pachinko ball collecting device 5, the fixing member 90 is inserted into the sliding groove 81 of the mounting base 80, and then the sliding guide plate 82 is attached to the mounting base 80 by the mounting screw 86. Install. Then, the positioning screw 56 inserted into the positioning hole 55 of the main body base 50 and the insertion groove 84 of the sliding guide plate 82 is screwed into the fixing screw hole 91 of the fixing member 90. Thereby, as shown in FIG. 13, the mounting base 4 is assembled and the main body base 50 is attached to the mounting base 4. At this time, the fixing member 90 moves upward by rotating the fixing screw hole 91 clockwise, and the upper surface of the fixing member 90 comes into contact with the lower surface of the sliding guide plate 82 as shown in FIG. It will be. Thus, by tightening the positioning screw 56, the sliding guide plate 82 is sandwiched between the fixing member 90 and the main body base 50, so that the main body base 50, that is, the pachinko ball collecting device 5 is attached to the mounting base 4. It will be fixed. The mounting base 4 is attached to the pachinko island base 1 with a fixing screw 85.

  The left / right slide mechanism of the pachinko ball collecting device 5 assembled as described above loosens the positioning screw 56 and holds the slide guide plate 82 when the position of the pachinko ball collecting device 5 is moved in the left / right direction. Is released. By releasing the holding of the sliding guide plate 82, the main body base 50 provided with the pachinko ball collecting device 5 can be moved. Therefore, the pachinko ball collecting device 5 is moved to a desired position, and the positioning screw 56 is again set. By tightening, the pachinko ball collecting device 5 can be fixed at an arbitrary position.

  As described above, the configuration of the front and rear and left and right slide mechanisms of the pachinko ball collecting device 5 has been described. Next, a chamfered portion provided to prevent clogging of pachinko balls in the ball receiving portion 10 of the pachinko ball collecting device 5. 22 will be described.

  As described above, the movement of the pachinko balls in the ball receiver 10 of the pachinko ball collecting apparatus 5 is as shown in FIG. 20A when the amount of the pachinko balls in the ball receiver 10 is small. The pachinko balls received at the falling position of the ball are divided into a plurality of directions so as to bounce and spread from the falling position, and the pachinko balls roll toward the upstream side of the ball discharging portion 11 and are aligned in a line by the ball discharging portion 11. On the other hand, when the amount of pachinko balls in the ball receiving portion 10 is large, as shown in FIG. 20B, the pachinko on the inclined bottom surface 12 on the ball discharging portion 11 side rolls. The ball is guided to the ball discharge unit 11 so as to cover the pachinko ball already rolling on the ball discharge unit 11 and aligned with the pachinko balls in the ball discharge unit 11 so that the ball discharge unit 11 is aligned. Rolling Ku.

  However, by rotating the ball receiver 10 about its center as a rotation axis, the outer peripheral wall 15 and the ball discharge constituting the outer periphery of the ball receiver 10 are changed when the fall position of the pachinko ball on the inclined bottom surface 12 is changed. The flow of pachinko balls toward the vicinity of the corner portion 21 formed on the inner side surface of the connecting portion with the side wall 20 constituting the side surface of the portion 11 may become extremely large. In such a case, in the experiment by the present applicant, clogging may occur in the vicinity of the corner portion 21, more specifically, in the ball discharge portion 11 located below the corner portion 21. Therefore, in the pachinko ball collecting apparatus 5 according to the present embodiment, in order to prevent this clogging, the pachinko balls in the ball receiving portion 10 in the vicinity of the corner portion 21 are actively sent to the ball discharge portion 11 in the corner portion 21. A chamfer 22 for guiding is formed.

  Specifically, as shown in FIG. 21, a chamfered portion 22 formed by a tangent line b on the inner surface of the outer peripheral wall 15 passing through an intersection 23 between the chamfered portion 22 and the inner surface of the outer peripheral wall 15 and an extension line a of the chamfered portion 22. The angle B on the surface side is set to 90 ° or less. Further, the angle A on the surface side of the chamfered portion 22 formed by the tangent line c on the inner surface of the side wall 20 passing through the intersection 24 between the chamfered portion 22 and the inner surface of the side wall 20 and the extension line a of the chamfered portion 22 is set to 90 ° or less. ing. Since it is configured in this manner, the pachinko balls that roll along the outer peripheral wall 15 change the rolling direction at an angle of 90 ° or less by the chamfered portion 22 and guide them to the ball discharge portion 11. .

  Thereby, even if the position of the pachinko ball falling on the ball receiving portion 10 is changed and the number of pachinko balls heading toward the corner portion 21 is increased, the pachinko ball rolling along the outer peripheral wall 15 is 90 by the chamfered portion 22. Since the rolling direction is changed at an angle of less than or equal to the angle and guided to the ball discharge unit 11, the force generated by the pachinko ball guided toward the ball discharge unit 11 and the force generated by the pachinko ball discharged from the ball discharge unit 11 And the pachinko balls will not stop moving. From the above, even if the fall position of the pachinko ball on the ball receiving portion 10 is changed, a large amount of pachinko balls received by the ball receiving portion 10 are smoothly generated without causing clogging. And the pachinko balls can be smoothly discharged from the ball discharge portion 11 to the out ball collection basket 6 which is a predetermined collection basket.

  Note that the chamfered portion 22 according to the above-described embodiment has a slightly flat shape at the tip of the corner portion 21, but is not limited to this, and as shown in FIG. The wall part 59 may be provided between them, and the chamfered part 22 may be formed long.

A second projection upper fitting portion 115 into which the second projection 123 is fitted is formed in the lateral direction. A second cover upper positioning convex portion 116 that projects into the second cover positioning concave portion 124 formed on the lower surface of the second projection 123 protrudes below the second projection upper fitting portion 115.

  Next, as shown in FIG. 25, the second cover member 102 is constituted by a second cover body 120 formed in a cylindrical shape, and a second cover member 120 is formed on the upper portion of the second cover body 120 in the outer circumferential direction. A cover upper flange 121 protrudes, and a second cover lower flange 122 protrudes toward the inner periphery at the lower portion. Moreover, the 2nd protrusion 123 inserted by the above-mentioned 2nd cover attaching part 110 is protrudingly provided toward the inner peripheral direction in two places which the 2nd cover lower flange 122 faces. On the lower surface of the second protrusion 123, a second cover positioning recess 124 into which the above-described second cover lower positioning protrusion 113 is fitted is formed.

In addition, at two locations facing the third cover lower flange 142, third protrusions 143 fitted into the above-described third cover mounting portion 125 are provided so as to protrude in the inner circumferential direction. A third cover positioning recess 144 into which the above-described third cover lower positioning protrusion 128 is fitted is formed on the lower surface of the third protrusion 143.

  Thus, in order to assemble the extendable cover 100, first, the first cover member 101 is inserted into the second cover member 102 from above. At this time, the position of the first cover member 101 is adjusted so that the second protrusion 123 of the second cover member 102 is inserted into the second protrusion insertion groove 111 of the first cover member 101. After the second protrusion 123 is inserted into the second protrusion insertion groove 111, the first cover member 101 is rotated clockwise, whereby the second protrusion 123 is inserted into the second protrusion lower insertion portion 112 and the second protrusion 123 is inserted into the second protrusion insertion groove 111. The cover positioning recess 124 is fitted into the second cover lower positioning protrusion 113, and the first cover member 101 is fixed to the second cover member 102.

  Next, the second cover member 102 to which the above-described first cover member 101 is fixed is inserted into the third cover member 103 from above the inside. At this time, the position of the second cover member 102 is adjusted so that the third protrusion 143 of the third cover member 103 is inserted into the third protrusion insertion groove 126 of the second cover member 102. After the third protrusion 143 is inserted into the third protrusion insertion groove 126, the third protrusion 143 is inserted into the third protrusion lower insertion portion 127 by rotating the second cover member 102 in the clockwise direction. The third cover lower positioning projection 128 is fitted into the cover positioning recess 144, and the second cover member 102 is fixed to the third cover member 103.

  Then, by arranging the first cover member 101 on the outer periphery of the outer peripheral wall 15 of the ball receiver 10, the extendable cover 100 is attached to the pachinko ball collecting device 5. At this time, the position of the first cover member 101 is adjusted so that the attachment protrusion 16 of the ball receiving portion 10 is inserted into the protrusion insertion portion 107 of the first cover member 101. After the attachment protrusion 16 is inserted into the protrusion insertion portion 107, the first cover member 101 is rotated in the clockwise direction so that the attachment protrusion 16 is fitted into the protrusion insertion portion 108 and the attachment protrusion is inserted into the first cover positioning recess 109. Positioning protrusions that project from the lower surface of 16 are fitted, and the first cover member 101 is fixed to the ball receiver 10. That is, the extendable cover 100 is fixed to the pachinko ball collecting device 5. As described above, as shown in FIG. 27 (A), the stretchable cover 100 is attached to the pachinko ball collecting device 5 in a state of being contracted in the vertical direction.

  In order to change the stretchable cover 100 from the stretched state in the vertical direction as described above to the stretched state in the vertical direction as shown in FIG. 27B, first, the third cover member 103 is rotated clockwise. The third protrusion 143 is moved to the position of the third vertical movement groove 129 of the second cover member 102. After the third protrusion 143 is moved to the position of the third vertical movement groove 129, the third cover member 103 is moved upward. At this time, the third protrusion 143 moves in the third vertical movement groove 129. If the third cover member 103 is moved upward as it is, the upper surface of the third cover lower flange 142 abuts on the lower surface of the second cover upper flange 121, so that the third cover member 103 is moved upward from this position. I can't do that. By rotating the third cover member 103 counterclockwise from this state, the third protrusion 143 is inserted into the third protrusion upper insertion portion 130 and the third cover upper positioning protrusion is inserted into the third cover positioning recess 144. 131 is inserted, and the third cover member 103 is fixed at a position above the second cover member 102.

After the second protrusion 123 is moved to the position of the second vertical movement groove 114, the second cover member 102 is moved upward. At this time, the second protrusion 123 moves in the second vertical movement groove 114. If the second cover member 102 is moved upward as it is, the upper surface of the second cover lower flange 122 abuts against the lower surface of the first cover flange 105, and therefore the second cover member 102 is moved upward from this position. Can not be. By rotating the second cover member 102 counterclockwise from this state, the second protrusion 123 is inserted into the second protrusion upper insertion portion 115 and the second cover upper positioning protrusion is inserted into the second cover positioning recess 124. 116 is inserted, and the second cover member 102 is fixed at a position above the first cover member 101.
