  Hereinafter, an embodiment of the present invention will be described.

  FIG. 1A is a front view of a slide unit 1 according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view taken along line AA of the slide unit 1 shown in FIG. .

  The slide unit 1 according to the present embodiment is for moving an object such as an accessory placed in a window frame of a pachinko gaming machine. As shown in the figure, the slide unit 1 has the same shape. It has two rails 2a, 2b and one joint 3 that connects the two rails 2a, 2b so as to be relatively slidable. The slide unit 1 moves an object such as an accessory attached to the rail 2a or the rail 2b by relatively sliding the two rails 2a and 2b connected by the joint 3.

  2A is a front view of the rails 2a and 2b, and FIG. 2B is a cross-sectional view taken along the line BB of the rails 2a and 2b shown in FIG. 2A.

  The rails 2a and 2b are formed of a thermoplastic resin having excellent sliding characteristics such as a polyacetal resin impregnated with lubricating oil as necessary. As illustrated, the rail 2a is formed with a guide hole 20a having a pair of wall surfaces 211a and 212a arranged in parallel along the longitudinal direction. Similarly, the rail 2b is formed with a guide hole 20b having a pair of wall surfaces 211b and 212b arranged in parallel along the longitudinal direction.

  3 (A), 3 (B) and 3 (C) are a front view, a side view and a rear view of the joint 3, and FIG. 3 (D) is a view of the joint 3 shown in FIG. 3 (A). It is CC sectional drawing.

  The joint 3 is a thermoplastic resin excellent in sliding properties such as polyester resin impregnated with a lubricating oil as necessary, and is different from the thermoplastic resin such as polyacetal resin used for the rails 2a and 2b. As shown in the drawing, the joint body 30, the flange 33 formed at one end 31 a of the joint body 30, and the snap fit 34 a formed at the other end 31 b of the joint body 30 are illustrated. To 34d and slits 35a to 35d.

  The joint body 30 is a cylindrical body whose cross section perpendicular to the direction of the axis O is rectangular, and the length L of one side is slightly shorter than the widths Wa and Wb of the guide holes 20a and 20b of the rails 2a and 2b. Each of the four side surfaces 32a to 32d is formed with a sliding surface 36 that is in sliding contact with the pair of wall surfaces 211a and 212a of the guide hole 20a of the rail 2a and the pair of wall surfaces 211b and 212b of the guide hole 20b of the rail 2b. Has been. The joint 3 is configured such that the two rails 2a and 2b are relatively slidable in the longitudinal direction by inserting the joint body 30 into both the guide holes 20a and 20b of the two rails 2a and 2b. Connect to

The joint body 30 of the joint 3 is slidably contacted with the pair of wall surfaces 211a and 212a of the hole 20a and slidably contacted with the pair of wall surfaces 211b and 212b of the guide hole 20b formed in the rail 2b. The joint 3 connects the two rails 2a and 2b so as to be relatively slidable in the same direction X when inserted into the guide holes 20a and 20b. Thereby, it becomes possible to move objects, such as an accessory attached to the rail 2a or the rail 2b, in the direction X.

  Moreover, as shown in FIG. 4 (B), the pair of side surfaces 32b and 32d and the side surfaces 32a and 32c formed on the joint body 30 of the joint 3 are formed on the side surfaces 32b and 32d. The sliding surface 36 is in sliding contact with the pair of wall surfaces 211a and 212a of the guide hole 20a formed in the rail 2a, and the sliding surface 36 formed on the side surfaces 32a and 32c is arranged in a direction perpendicular to the rail 2a. The joint body 30 of the joint 3 is inserted into the guide holes 20a and 20b formed in the two rails 2a and 2b so as to be in sliding contact with the pair of wall surfaces 211b and 212b of the guide hole 20b formed in the rail 2b. In this case, the joint 3 connects the two rails 2a and 2b so as to be slidable in the direction X and the direction Y perpendicular to the direction X. Thereby, it becomes possible to move objects, such as the accessory attached to the rail 2a or the rail 2b, to the two directions of the direction X and the direction Y.

  The embodiment of the present invention has been described above.

  In the slide unit 1 according to the present embodiment, the joint body 30 of the joint 3 is inserted into the guide holes 20a and 20b of the two rails 2a and 2b to connect the two rails 2a and 2b, and the rail 2a. A pair of wall surfaces 211a, 212a arranged in parallel along the longitudinal direction of the guide hole 20a formed in the rail and a pair of wall surfaces 211b arranged in parallel along the longitudinal direction of the guide hole 20b formed in the rail 2b, Each of 212b is formed on two pairs of mutually parallel sliding surfaces 36 of the joint body 30 of the joint 3 (sliding surfaces 36 formed on the pair of side surfaces 32a and 32c, and a pair of side surfaces 32b and 32d. The sliding surfaces 36) are brought into sliding contact with each other, thereby moving the rails 2a and 2b in a direction determined by the sliding surfaces 36. Therefore, a pair of wall surfaces 211a and 212a arranged in parallel along the longitudinal direction of the guide hole 20a of the rail 2a and a pair of wall surfaces 211b and 212b arranged in parallel along the longitudinal direction of the guide hole 20b of the rail 2b. By changing the pair of parallel sliding surfaces 36 that are in sliding contact with each other, it is possible to change the moving direction of an object such as an accessory attached to the rails 2a and 2b. Accordingly, the object can be moved in a plurality of directions.

  Further, in the slide unit 1 according to the present embodiment, the joint 3 includes four rectangular side surfaces 32a to 32d, the cross section perpendicular to the axial direction has a quadrangular outer shape, and the four side surfaces 32a to 32d.

And the four snap fits 34 a to 34 d and the four slits 35 a to 35 d formed at the other end 31 b of the joint body 30. Therefore, when the joint body 30 of the joint 3 is inserted into the guide holes 20a and 20b of the rails 2a and 2b, the side surfaces of the joint body 30 are formed by the slits 35a to 35d formed in the other end portion 31b of the joint body 30. 32a to 32d bend inward in the radial direction, whereby the snap fits 34a to 34d pass through the guide holes 20a and 20b of the rails 2a and 2b. The flange 33 of the joint 3 abuts on one surface of the two rails 2a and 2b (the surface 22a of the rail 2a in FIG. 1), and the snap fits 34a to 34d are the other back surfaces of the two rails 2a and 2b. (In FIG. 1, the rear surface 23b of the rail 2b) is engaged. Therefore, the two connected rails 2a and 2b can be reliably held by the joint 3, and the joint 3 can be prevented from falling off from the rails 2a and 2b.

  For example, in the above embodiment, the case where two rails 2a and 2b are connected by one joint 3 has been described as an example, but the present invention is not limited to this. The M rails may be connected in a daisy chain using M (M is 3 or more) rails and M-1 joints. In this case, each of the joints is inserted into the guide holes of the two overlapping rails of the M rails, and connects the two rails. That is, one joint is inserted into the guide holes of each of the two rails positioned at the uppermost and lowermost positions of the M rails, and two rails are inserted into the guide holes of the remaining rails. A joint is inserted. For example, like a joint unit 1a shown in FIGS. 5A and 5B, three rails 2a to 2c and two joints 3a and 3b are used, and one joint 3a is used as a guide for the rail 2a. By inserting the hole 20a and the guide hole 20b of the rail 2b and inserting the other joint 3b into the guide hole 20b of the rail 2b and the guide hole 20c of the rail 2c, the rails 2a to 2c can be connected in a daisy chain. In this case, among the three rails 2a to 2c, one joint (joint 3a, 3b) is provided in each of the guide holes 20a, 20c of the two rails 2a, 2c positioned in the uppermost position and the lowermost position in the overlapped state. Is inserted, and two joints (both joints 3a and 3b) are inserted into the guide holes 20b of the remaining rail 2b.

  In the above embodiment, the joint 3 has a quadrangular outer shape in a cross section perpendicular to the axial direction of the joint body 30, but the present invention is not limited to this. The outer shape of the cross section perpendicular to the axial direction of the joint body of the joint may be an N (where N is an even number of 4 or more) square shape. For example, when a joint 3c having a joint body 30a having an octagonal outer shape in cross section perpendicular to the direction of the axis O, such as a joit unit 1b shown in FIG. 6, is attached to the rail 2a or the rail 2b. An object such as an accessory can be moved in more directions than in the above embodiment.

  In the above embodiment, the joint 3 has the flange 33 formed at one end 31a of the joint body 30 and the snap fits 34a to 34d formed at the other end 31b. It is not limited to this. Any joint may be used as long as the joint body is devised to prevent the joint body from falling out of the guide hole of the rail.

  7A, FIG. 7B, and FIG. 7C are a front view, a side view, and a rear view of a modified example 3d of the joint 3, and FIG. 7D is a view in FIG. 7A. It is EE sectional drawing of the modification 3d shown. Here, components having the same functions as those of the joint 3 shown in FIG.

  The joint 3d is a thermoplastic resin having excellent sliding characteristics such as a polyester resin impregnated with a lubricating oil if necessary, and is different from the thermoplastic resin such as the polyacetal resin used for the rails 2a and 2b. As shown in the figure, the joint body 30b, the flange 33a formed at the central portion 37c of the joint body 30b, and the snap fits 38a to 38a formed at both end portions 37a and 37b of the joint body 30b, respectively, are illustrated. 38d and slits 39a to 39d.

  8A is a front view of a modified example 1c of the slide unit 1 using the joint 3b shown in FIG. 7, and FIG. 8B is an FF of the modified example 1c shown in FIG. 8A. It is sectional drawing.

  As shown in the figure, in the slide unit 1c, the rail 2a is held between the snap fits 38a to 38d formed on one end 37a of the joint body 30b of the joint 3b and the flange 33a. It is held between the snap fits 38a to 38d formed at the other end 37b of the joint body 30b of 3b and the flange 33a. As a result, the flange 33a is interposed between the rail 2a and the rail 2b. Here, the joint 3b is formed of a thermoplastic resin different from the thermoplastic resin used for the rails 2a and 2b. Therefore, according to the modified example 1c of the slide unit 1, compared to the slide unit 1 according to the above-described embodiment in which the back surface 23a of the rail 2a and the front surface 22b of the rail 2b formed of the same material are in sliding contact with each other, It becomes possible to slide the rails 2a and 2b relatively smoothly.
