The automatic ticket gate 1 is a so-called simple automatic ticket gate installed outside a station or the like. The automatic ticket gate 1 includes a housing 11 and electrical components 12 provided in the housing 11. - 特許庁The automatic ticket gate 1 reads a non-contact type IC card and performs entrance processing and exit processing.

As shown in FIGS. 1 and 2, the housing 11 includes a main body 21, a cover 22, hinges 23, and packing 24. As shown in FIGS. In the present embodiment, the cover 22 of the housing 11 is defined as the front, and the front-rear direction and the vertical direction are defined in the following description. The housing 11 is provided with a cover 22 at the front, and is configured, for example, in the shape of a rectangular box with an inclined front.

As shown in FIGS. 1 and 2, the main body 21 has a bottom wall 31, a rear wall 32, a pair of side walls 33 and a top wall . The main body 21 has an opening 35 on the front and a flange 36 provided on the inner peripheral edge of the opening 35 . The main body 21 has a bottom wall 31 , a rear wall 32 , a pair of side walls 33 , a top wall 34 , an opening 35 and a flange 36 , and is shaped like a rectangular box with the front opening 35 and the flange 36 . be done. Further, the main body 21 is inclined forward such that, for example, the width in the depth direction gradually increases from the top wall 34 side toward the bottom wall 31 side.

The bottom wall 31 is attached, for example, to a pillar or the like that supports the automatic ticket gate 1 . The bottom wall 31, the rear wall 32 and the top wall 34 are configured in a rectangular shape. The pair of side walls 33 are configured in a trapezoidal shape with the front side inclined in accordance with the inclination of the main body 21 .

One side wall 33 of the pair of side walls 33 rotatably holds the cover 22 via the hinge 23 . The opening 35 opens in a rectangular shape. The opening 35 is set to have an opening area that accommodates the electrical equipment 12 in the housing 11 and that allows maintenance. For example, the opening 35 includes a rectangular edge portion 35a forming the front side of the main body 21, and opens in substantially the entire range of the front region of the main body 21 excluding the edge portion 35a. The edge portion 35 a is formed in a rectangular frame shape that is continuous with the bottom wall 31 , the pair of side walls 33 and the top wall 34 .

As shown in FIG. 2, the flange 36 is configured in the shape of a rectangular frame. Specifically, the flange 36 is provided at a rectangular frame-shaped wall portion 36a extending from the edge portion 35a of the opening 35, and at the end portion of the wall portion 36a. and a rectangular frame-shaped seal face portion 36b extending in the direction of

As shown in FIG. 2, the sealing surface portion 36b is, for example, a rectangular frame shape with four curved corners. That is, at least a portion of the four corners of the rectangular frame-shaped sealing surface portion 36b, for example, is curved with a predetermined radius of curvature when viewed from the front. One side of the seal surface portion 36b adjacent to the hinge 23 extends from the wall portion 36a toward one side paired in the left-right direction, and the other three sides extend to one side paired in the left-right direction or the up-down direction. It extends from the wall portion 36a.

In other words, the sealing surface portion 36b extends into the opening 35 at a portion 36b1 provided on the wall portion 36a adjacent to one side wall 33 on which the hinge 23 is provided, and extends into the bottom wall 31, the other side wall 33 and the top wall. A portion 36 b 2 provided on the wall portion 36 a adjacent to 34 extends outside the opening 35 . Further, the sealing surface portion 36b is configured such that the width of the portion 36b1 adjacent to one side wall 33 on which the hinge 23 is provided is slightly smaller than the width of the other portion 36b2.

At least the wall portion 36a of the flange 36 on the one side wall 33 side where the hinge 23 is provided and the ridge portion of the sealing surface portion 36b (portion 36b1) are formed into curved surfaces having a predetermined radius of curvature. That is, the edge of the flange 36 adjacent to one side wall 33 on which the hinge 23 is provided has a curved chamfer. The flange 36 is formed by bending and the like, and is processed by welding and polishing. Thus, for example, the flange 36 has a chamfer with a predetermined radius of curvature on all edges.

As shown in FIGS. 1 and 2, the cover 22 is formed in a rectangular shape and has an outer peripheral edge extending in a direction perpendicular to the main surface. The cover 22 has a mounting portion 22a for mounting the packing 24 in a range facing the sealing surface portion 36b of the flange 36 on the inner surface. The attachment portion 22a is attached to the inner peripheral surface of the cover 22, for example.

As shown in FIGS. 3 and 4, hinge 23 has one end fixed to the inner surface of one side wall 33 and the other end fixed to cover 22 . The rotation center of the hinge 23 is arranged on the side wall 33 side. The hinge 23 rotatably supports the cover 22 between a closed position where the cover 22 abuts against the main body 21 and an open position rotated by a predetermined angle, for example, about 90 degrees. For example, the hinges 23 are provided at two locations on one side wall 33 in the direction of gravity.

As shown in FIG. 2, the packing 24 is formed in an annular shape along the shape of the seal surface portion 36b. For example, in the present embodiment, since the seal surface portion 36b is configured in a rectangular frame shape, the packing 24 is configured in a rectangular annular shape. The packing 24 is attached to the attachment portion 22a by, for example, double-sided tape. A surface of the packing 24 to be attached to the attachment portion 22a is configured to be planar. The surface of the packing 24 that contacts the seal surface portion 36b is formed in a curved shape. As a specific example, the packing 24 has a semicircular cross section. The packing 24 is molded from a resin material such as rubber.

As shown in FIG. 2, the electrical equipment 12 includes, for example, a card reader/writer 12a, a substrate, a storage medium, a controller, and the like. The card reader/writer 12a is arranged on the cover 22, and is electrically connected to a board or the like provided on the main body 21 side by a cable 12b or the like.

Next, a method for manufacturing the housing 11 of the automatic ticket gate 1 configured as described above will be described with reference to FIGS. 7 to 9. FIG.
First, as shown in ST1 of FIGS. 7 and 8, first, a metal plate is bent into a box shape to form a bottom wall 31, a rear wall 32, a pair of side walls 33, a top wall 34, an edge portion 35a and a wall portion 36a. A first molding is performed to mold the At this time, the wall portion 36a is formed into a rectangular frame shape that is taller than the width of the sealing surface portion 36b when viewed from the side and forms the opening shape of the opening 35 when viewed from the front.

That is, after the first molding, the wall portion 36a has a bending allowance that constitutes the sealing surface portion 36b. The wall portion 36a is formed in a rectangular frame shape, and the length between the pair of walls 36a1 forming the long sides is the same as the length in the longitudinal direction of the pair of walls 36a2 forming the short sides. be.

Next, as shown in step ST2 in FIGS. 7 and 8, the wall portion 36a is bent to form a pair of first bent portions 36a3 and a pair of second bent portions 36a4 that form the seal surface portion 36b. Carry out molding. At this time, the wall 36a1 on one side wall 33 to which the hinge 23 is fixed is bent toward the wall 36a1 on the other side to form a first bent portion 36a3, and the other wall 36a1 and the pair of walls 36a2 are bent. are bent in the direction opposite to the pair of walls 36a1 and 36a2 to form a first bent portion 36a3 and a pair of second bent portions 36a4.

Thereby, the pair of first bent portions 36a3 extend in the same direction, and the pair of second bent portions 36a4 extend in opposite directions so as to be separated from each other. As a result, as shown in step ST2 in FIG. 8, the first bent portion 36a3 and the pair of second bent portions 36a4 on one side wall 33 side are arranged in a continuous U-shape. Also, the first bent portion 36a3 and the pair of second bent portions 36a4 on the other side wall 33 side are arranged apart from each other.

Next, as shown in step ST3 in FIG. 9, the welding device 110 welds the continuous first bent portion 36a3 and the pair of second bent portions 36a4. Further, as shown in step ST3 in FIG. 9, a small piece 36c is arranged to connect the first bent portion 36a3 and the pair of second bent portions 36a4 on the side of the other side wall 33, and the welding device 110 welds the small piece 36c and the other side. The first bent portion 36a3 and the pair of second bent portions 36a4 on the side wall 33 side are welded.

Next, as shown in step ST4 of FIG. 9, the welded portion 130 produced in step ST3 is polished by the polishing device 120 to obtain a predetermined surface roughness. Through this step, the seal surface portion 36b is formed by integrally forming the pair of first bent portions 36a3 and the pair of second bent portions 36a4 into a rectangular frame shape. Through these steps, the housing 11 is molded.

According to the automatic ticket gate 1 having the housing 11 configured in this way, when the cover 22 rotates around the rotation center of the hinge 23 from the open position shown in FIG. 5 to the closed position shown in FIG. The packing 24 abuts against the seal surface portion 36b. At this time, the packing 24 comes into contact with the sealing surface portion 36b just before the cover 22 reaches the closed position, as indicated by the trajectory indicated by the two-dot chain line in FIG. , and comes into close contact with the sealing surface portion 36b. As a result, the main body 21 and the cover 22 are sealed by the packing 24, so that the housing 11 has high waterproof performance.

A seal surface portion 36b on the side wall 33 of the flange 36 where the hinge 23 is provided extends from the wall portion 36a toward the inside of the opening 35. As shown in FIG. Therefore, when the cover 22 is in the open position, the distance between the packing 24 and the sealing surface portion 36b can be maximized. That is, the flange 36 can be removed from the movement locus of the packing 24 when the cover 22 rotates. This can prevent the packing 24 from interfering with the flange 36 as much as possible during the opening/closing operation of the cover 22 . In other words, it is possible to prevent the packing 24 from being pressed by the flange 36 in a direction opposite to the direction of rotation.

In addition, the packing 24 has a semicircular cross section and the corners of the flange 36 are chamfered to prevent contact between the packing 24 and the flange 36 as much as possible. Further, since the shape of the packing 24 and the flange 36 abutting against each other is a curved surface shape, the force along the rotation direction of the cover 22 is resolved when the packing 24 and the flange 36 abut against each other.

That is, since the contact surface between the packing 24 and the flange 36 is a curved surface, when the packing 24 and the flange 36 contact each other, the flange 36 moves outward from the center of curvature of the moving locus of the packing 24. The packing 24 is pressed in the radial direction. Therefore, the packing 24 is elastically deformed in the same radial direction, and interference with the flange 36 is reduced. Therefore, the force applied to the packing 24 in the direction of rotation of the cover 22 when the packing 24 comes into contact with the flange 36 can be reduced.

Furthermore, since the corners of the flange 36 are chamfered, it is possible to prevent the flange 36 from damaging the packing 24 even when the main body 21 is made of a metal material.

With these configurations, the housing 11 can prevent the packing 24 from being pressed by the flange 36 when the cover 22 is opened and closed. Damage can be prevented as much as possible. Since the life of the packing 24 can be improved in this way, the waterproof performance of the housing 11 and the automatic ticket gate 1 can be ensured.

Also, since a portion of the seal surface portion 36b of the flange 36 is bent inward of the opening 35 and then welded, the first bent portion 36a3 and the pair of second bent portions 36a4 can be directly welded. As a result, the number of locations where the small pieces 36c are used can be reduced, so the cost of the small pieces 36c, the steps for arranging the small pieces 36c, and the welding locations can be reduced. As a result, manufacturing costs in the welding process can be reduced.

In addition, since the number of welded parts can be reduced in polishing performed after welding, the polishing process and the range of polishing can be reduced, and the manufacturing cost in the polishing process can be reduced. For these reasons, the manufacturing cost of the housing 11 can be reduced.

In addition, since the automatic ticket gate 1 is provided with the card reader/writer 12a on the cover 22 for processing IC cards, it is connected to other components of the electrical equipment 12 such as a substrate via a cable 12b or the like. Therefore, when the cover 22 is opened and closed, the cable 12b also moves. However, since the housing 11 can increase the distance between the cover 22 and the flange 36 as much as possible, it is possible to prevent the cables 12b and the like from being caught between the cover 22 and the flange 36.

In addition, in the flange 36, the width of the portion 36b1 of the seal surface portion 36b extending toward the opening center of the opening 35 is narrower than the other portions 36b1 and 36b2. With this configuration, it is possible to prevent the cable 12b from being caught between the packing 24 and the seal surface portion 36b, and to prevent the opening area of the flange 36 from being smaller than the opening area of the opening 35 by the portion 36b1.

As described above, according to the automatic ticket gate 1 having the housing 11 according to the present embodiment, waterproof performance can be ensured.

In addition, embodiment is not limited to said structure. For example, in the above-described example, the flange 36 has the sealing surface portion 36b in the shape of a rectangular frame and the four corners on the outer surface side are curved, but the shape is not limited to this. The flange 36 may have the corners of the sealing surface portion 36b left in a right-angled shape, or may have a shape in which the corners are removed so as to be inclined along the longitudinal sides of the flange 36 . In other words, the shape of the four corners of the flange 36 is not limited as long as at least the sealing surface portion 36b is formed in a rectangular frame shape with mutually opposing sides and sides orthogonal to these sides.

In addition, if interference with the packing 24 can be suppressed as much as possible, waterproof performance can be ensured by abutting the packing 24, and an opening that allows a part of the electrical component 12 to be arranged in the main body 21 can be formed, the flange 36 can be formed. The shape may be a shape other than a rectangular frame shape. For example, the shape of the flange 36 other than the rectangular frame shape may be another rectangular frame shape, such as a trapezoidal frame shape, a parallelogram frame shape, or a polygonal frame shape other than the rectangular frame shape. . Further, the shape of the flange 36 may be, for example, a frame shape in which a pair of long sides are parallel straight lines and a pair of short sides are curved with a predetermined radius of curvature. When the flange 36 has a shape other than a rectangular frame shape, the packing 24 may have an annular shape along the shape of the seal surface portion 36b.

Also, although the flange 36 has been described as having a configuration in which the sealing surface portion 36b extends in the direction orthogonal to the wall portion 36a, the present invention is not limited to this. For example, like the flange 36A of the main body 21 according to the second embodiment shown in FIG. 10, at least the shape of the side wall 33 side on which the hinge 23 is provided of the flange 36A is shaped like a frame whose cross-sectional shape is curved with a predetermined radius of curvature. may be configured.

The flange 36</b>A having such a configuration is retracted as much as possible from the trajectory of the tip of the packing 24 when the cover 22 is opened and closed, and the curved surface constitutes a seal surface portion that abuts on the packing 24 . Thus, like the flange 36 described above, it is possible to prevent the packing 24 from interfering with the flange 36A when opening and closing the cover 22, and to resolve the force generated when the flange 36A comes into contact with the packing 24. .

Similarly, like the flange 36B of the main body 21 according to the third embodiment shown in FIG. 11, the corners of the flange 36B may be provided with planar chamfered portions 36d. The flange 36B having such a configuration produces the same effect as the flanges 36, 36A described above.

Further, in the above-described example, the configuration in which the surface of the packing 24 that contacts the flange 36 is curved is described, but the configuration is not limited to this and can be set as appropriate. For example, the packing 24 may have a rectangular cross section, or may have a chamfered shape in which the ridges are flat and inclined. However, the packing 24 preferably has a shape that can reduce interference with the flange 36 .

In the above example, the case 11 is used for the automatic ticket gate 1, but it is used for other devices that require waterproof performance and in which the cover 22 rotates about one axis with respect to the main body 21. can also Also, in the above example, the main body 21 has a configuration in which the hinge 23 is provided on one side wall 33, but the present invention is not limited to this. For example, the hinge 23 may be provided on the bottom wall 31 or may be provided on the top wall 34 . That is, it is sufficient that the portion of the flange 36 on the side where the side wall 33 of the hinge 23 is provided that abuts against the packing 24 is moved toward the center of the main body 21 .

While several embodiments of the invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention.
