The storage frame 10 includes an upper frame portion 11, a lower frame portion 12, a right frame portion 13, and a left frame portion 14 having a wall surface structure formed to extend in the rear surface direction of the front frame 2, and these upper, lower, left and right frame portions. 11, 12, 13, and 14 are formed integrally with the front frame 2 so as to surround the periphery of the game board 20. The inner space between the left and right frame parts 13 and 14 in the housing frame 10 is formed to be about 1 to 2 mm larger than the width dimension of the decorative plate 21, and the inner surface distance between the upper and lower frame parts 11 and 12 is several times larger than the height dimension of the decorative plate 21. It is formed large about mm. Each part of the housing frame 10 is formed with tongue-plate-shaped or corner-frame-shaped plate portions 11 a, 12 a, 13 a, and 14 a that protrude from the inner surface of each frame part toward the inside of the housing frame 10. Each of the contact plate portions 11 a, 12 a, 13 a, and 14 a is formed in the frame so as not to protrude rearward of the housing frame 10, and is configured such that the rear end surface of the housing frame 10 is flat.
[0023]
On the other hand, on the back side of the decorative plate 21, the plate receiving portions 41a, 42a, 43a, and 44a (see FIGS. 4 to 15 are described in detail later) in accordance with the formation positions of the plate portions 11a, 12a, 13a, and 14a. Is formed. Each of the contact plate receiving portions 41a, 42a, 43a, 44a is formed by counterboring the back surface of the decorative plate 21 by the thickness of the contact plate portion according to the position and shape of the contact plate portions 11a, 12a, 13a, 14a. When the decorative plate 21 is accommodated and held in the accommodating frame 10, the rear end surface of the accommodating frame 10 and the back surface of the decorative plate 21 are aligned and flattened.
[0024]
Now, in the storage frame 10 configured as described above, the locking mechanisms 50 are disposed at the two left and right positions of the lower frame portion 12. A side sectional view of the vicinity of the locking mechanism 50 viewed in the direction of arrow IV in FIG. 3 is shown in FIG. 4, and a perspective view of the mechanism 50 viewed from the back side of the housing frame 10 is shown in FIG. The locking mechanism 50 will be described with reference to the drawings.
[0025]
The locking mechanism 50 is mainly configured by a locking metal fitting 51 that is attached so as to sandwich the lower frame portion 12 and protrudes upward. The locking bracket 51 includes a base portion 51a supported on the upper surface of the lower frame portion 12, a front side of the base portion 51a bent upward and a locking side portion 51b protruding upward, and a rear side of the base portion 51a bent downward. The rear side 51c that extends downward, the lower part of the rear side 51c is folded forward, extends parallel to the base 51a, and sandwiches the lower frame 12 up and down, and the front end side of the sandwiching side 51d faces downward It is composed of a fixed side portion 51e or the like that is bent in the direction and extends downward and through which a screw 58 is inserted.
[0026]
The distance between the rear surface of the locking side portion 51b and the rear end surface of the rear side portion 51c, that is, the front-rear dimension of the upper surface of the base portion 51a is set to be the same as or slightly smaller than the plate thickness of the decorative plate 21. . Further, the upper end portion of the locking side portion 51b is gently bent toward the front, smoothly receiving and guiding the lower end portion of the decorative board 21, and preventing the surface of the decorative board from being scratched. The locking bracket 51 is formed of a metal material such as a stainless steel plate or a cold-rolled steel plate having a thickness of about 1 to 2 mm into a shape shown in the drawing using a known processing means such as punching, bending, or press forming, and if necessary. Then, it is formed by applying the required surface treatment.
[0027]
On the other hand, the rear edge of the lower frame portion 12 is cut out by the thickness of the locking metal 51 at the attachment position of the locking metal 51 to form a receiving notch 12c. The rear side 51c of the locking bracket 51 is received in the receiving notch 12c, and the rear end surface of the rear side 51c is flush with the rear end surface of the receiving frame 10 including the left and right lower frame portions 12. Are arranged. A cylindrical boss 12b that supports the front surface of the fixed side portion 51e is formed below the receiving notch 12c, and a screw receiving portion that receives the screw 58 is formed at the center thereof.
[0028]
Further, corner frame-shaped contact plate portions 12 a and 12 a are formed at the left and right ends of the lower frame portion 12 so as to connect the lower frame portion 12 and the left and right frame portions 13 and 14. On the left and right corners on the side, there is formed a pad receiving part 42a that is counterbored by the thickness of the pad 12a according to the shape of the pad 12a. The lower end edge of the decorative plate 21 has a corner on the back side cut obliquely to form a flank 42e.
[0029]
The locking metal 51 is placed on the upper surface of the lower frame 12 in accordance with the position where the receiving notch 12c is formed, and the locking metal 51 is slid forward to move the base 51a and the clamping side part. The lower frame portion 12 is fitted and connected so as to sandwich the lower frame portion 51d, and the screw 58 is screwed and fastened to the boss 12b through the attachment hole from the rear of the fixed side portion 51e to be attached to the lower frame portion 12.
[0030]
When the locking metal fitting 51 is thus attached, the base portion 51 a is supported on the upper surface of the lower frame portion 12, and the locking side portion 51 b is disposed so as to protrude upward on the front side of the lower frame portion 12. The rear end surface of the rear side portion 51 b is disposed on the same plane as the rear end surface of the storage frame 10, and the locking side portion 51 b has a longitudinal dimension between the rear surface and the rear end surface of the storage frame 10 of the decorative plate 21. It is disposed in the front-rear direction position that is the same size as the plate thickness or slightly smaller.
[0031]
When the game board 20 is mounted on the locking mechanism 50 configured as described above, the left and right edges of the decorative board 21 from the front side of the game board 20 with the glass door 5 and the upper ball tray 6 opened. The game board 20 is supported in a slightly forward tilted posture by gripping the portion, and the lower end portion of the decorative board 21 is inserted into the housing frame 10 obliquely from above the locking side portion 51b.
[0032]
Here, as shown in FIGS. 3 and 4, the height of the contact plate portion 12 a is formed to be larger than the protruding height of the locking side portion 51 b. For this reason, when the lower end portion of the decorative plate 21 is inserted obliquely into the housing frame, the left and right contact plate receiving portions 42a are respectively guided by being engaged with the front surface of the contact plate portion 12a, and the decorative plate 21 is moved downward. By sliding and moving, the two locking side portions 51b can be engaged at the appropriate position on the front surface of the decorative board. Since the upper end portion of the locking side portion 51b is gently bent toward the front, the decorative plate 21 slid downward is guided smoothly to the base portion 51a at the lower end portion. The side part 51b and the base part 51a are elastically deformed to receive the decorative board 21 in an inclined posture. As a result, the game board 20 is elastically biased and supported on the base portion 51a in a forward inclined posture.
[0033]
In addition, since the flank 42e is formed in the back surface lower end part of the decorative board 21, even if the game board 20 is inserted / extracted in an inclined posture or is swung up and down, the lower end part of the decorative board 21 remains in the housing frame 10. Even if the back set board 30 is closed and held so as to be in close contact with the rear end face of the storage frame 10 without protruding rearward from the rear end face, excessive stress is applied to the back set board 30. Is not generated.
[0034]
Further, the rear end side of the locking metal fitting 51 is bent in a U-shape to form a holding side portion 51d so as to hold the lower frame portion 12 therebetween. For this reason, even if a force that tilts the locking side 51b forward acts and the locking side 51b and the base 51a are elastically deformed, the holding side 51d transmits this force to the lower frame 12. So that it does not act directly on the fixed side 51e. Therefore, an excessive bending moment or pulling force does not act on the boss 12b via the screw 58, and the boss 12b is not broken or the screw receiving portion is not damaged. In addition, by bending the locking fitting in this way, the length of the elastically deformable region can be increased, and a locking mechanism that is flexible and difficult to plastically deform can be configured in a small size.
[0035]
In the embodiment, the locking side portion 51b of the locking bracket is bent at a right angle with respect to the base portion 51a, and the front-rear dimension between the rear surface of the locking side portion 51b and the rear end surface of the housing frame 10 is the decorative plate 21. However, the locking mechanism 50 is not limited to such a configuration, and can lock the lower end portion of the decorative plate 21. If it is. For example, in the case where the same locking metal fitting as in the embodiment is provided, a gap slightly larger than the thickness of the decorative plate 21 is provided between the lower end of the locking side and the rear end surface of the housing frame. The locking side part 51b is formed at a right angle with respect to the base part 51a with a space slightly smaller than the thickness of the decorative plate 21 between the upper part of the locking side part and the rear end surface of the housing frame. Alternatively, it may be bent at a small angle and protrude in a slightly tilted posture. In such a locking mechanism, even if there is some variation in the thickness of the decorative plate 21, the locking bracket elastically absorbs, and a gap is formed between the decorative plate and the locking bracket is excessive. No stress is generated.
[0036]

[0054]
Now, the operation of the temporary support mechanism 60 and the fixing mechanism 70 configured as described above will be described with reference to FIGS. 11 and 12 from the case where the game board 20 is first mounted on the storage frame 10. Here, FIG. 11 is an explanatory view (side sectional view) showing the operation of the temporary support mechanism 60 when the game board 20 is mounted on the storage frame 10, and FIG. 12 is a temporary support when the game board 20 is temporarily fixed and supported. It is explanatory drawing (side sectional drawing) which shows the effect | action of the mechanism 60 with a continuous line, and shows the effect | action of the temporary support mechanism 60 when the game board 20 is fixedly held, and the fixing mechanism 70 with a dashed-two dotted line.
[0055]
The operator rotates the operation bolt 72 to swing the fixing bracket 71 upward and retracts the fixing bracket 81 in the side fixing mechanism 80 described later while swinging upward or downward. Using the locking mechanism 50 described above, the lower end portion of the decorative board 21 is inserted into the housing frame 10 at an angle, and the game board 20 is elastically supported on the base portion 51a in a forward tilt posture. In this state, when the operator weakens the force in the forward tilt direction, the upper part of the game board 20 swings backward due to the elastic force of the locking fitting 51, and as shown in FIG. The introduction surface 41 e of the upper edge engaging portion 41 is locked in a temporary support posture in contact with the introduction side portion 61 e of the temporary fixing metal fitting 61.
[0056]
When the operator presses the upper part of the game board 20 backward from this state, the introduction side portion 61e is guided to the introduction surface 41e and moved up to slide on the slope of the introduction surface 41e, and the front end side of the swing arm portion 61b. Is elastically deformed so as to swing upward, allowing the decorative plate 21 to enter. When the introduction side portion 61e moves to the upper end of the introduction surface 41e, the second engagement side portion 61d slides on the upper side portion 41d, and the decorative plate 21 further advances inward of the housing frame 10. Here, the upper frame portion 11 is formed with a receiving groove 11e positioned above the introduction side portion 61e, and is introduced when the introduction side portion 61e is moved upward by swinging the swing arm portion 61b. The side 61e is received and retracted, and the decorative board 21 can be smoothly attached and detached.
[0057]
When the swinging movement of the decorative plate 21 toward the inside of the housing frame 10 progresses and the rear corner of the second engagement side 61d reaches the front end of the upper side 41d, the elasticity stored in the swing arm 61b is stored. Due to the force, the rear corner portion of the second engagement side portion 61d moves down so as to slide down the slope of the lead-out surface 41f, and the first engagement side portion 61c is moved to the first engagement surface 41c as shown by the solid line in FIG. And the arm portion returns to the shape before elastic deformation. Further, at this time, the backing plate receiving portion 41a of the decorative plate comes into contact with the backing plate portion 11a, and the game board 20 is temporarily fixed in the storage posture stored in the storage frame 10.
[0058]
In this temporarily fixed state, the first engagement side portion 61c of the temporary fixing metal fitting 61 and the first engagement surface of the upper edge engagement portion 41 of the decorative plate are engaged at a predetermined engagement height of, for example, about 1 mm. Therefore, even if the operator releases the pressing force that pushes the decorative plate 21 backward, the game board 20 is maintained in the storage posture stored in the storage frame 10.
[0059]
The operator rotates the operation bolt 72 from the front of the game board 20 temporarily fixed in this way using a hexagon wrench or the like, and swings the fixing bracket 71 downward. When the fixing bracket 71 is swung, the distal end side of the fixing bracket moves downward along an arc trajectory, and first, the curved area of the first pressing portion 71c gently bent forward is the first engagement side of the locking bracket. It smoothly engages with the upper part of the part 61c. Further, when the fixture 71 is swung downward, the flat region on the proximal end side engages with the first engagement side portion 61c as the curved surface region on the distal end side moves downward, and the first engagement side portion 61c. Press backwards. Further, as the fixing bracket 71 swings, the second pressing portion 71d at the tip engages with the second engaging side portion 61d of the locking bracket and presses downward, and the fixing bracket 71 swings downward. Then, the first engagement side portion 61c moves downward along the first support surface 41c, and the second engagement side portion 61d is pressed and moved downward while elastically deforming the support arm 61a and the swinging arm portion 61b. .
[0060]
Then, when the lever part 71a of the fixing bracket is swung to the angular position extending in the vertical vertical direction, the first pressing part 71c presses the first support surface 41c backward via the first engagement side part 61c. The decorative plate 21 is sandwiched between the back plate portion 41a and the second pressing portion 71d presses the second support surface 41d downward via the second engagement side portion 61d to contact the lower frame portion 12. The game board 20 is fixedly held in the accommodated posture with the decorative board 21 sandwiched therebetween (see FIG. 8).
[0061]
When the game board 20 is fixed and held in the storage frame 10 in this way, the contact plate portion 11a is received by the contact plate receiving portion 41a, and the rear surface of the decorative plate 21 and the rear end surface of the storage frame 10 are arranged on the same surface. The For this reason, the flat surface is formed in the back surface side of the storage frame 10, and the structure which improved the consistency with the back set board 30 closed behind this is implement | achieved. Further, the contact plate portion 11 a is formed so as to protrude from the inner surface of the upper frame portion 11 toward the inside of the housing frame 10, and the back surface side of the decorative plate 21 is counterbored to form the contact plate receiving portion 41 a. Therefore, the thickness dimension of the front frame 2 including the housing frame 10 can be configured to be thin.
[0062]
On the other hand, when the game board 20 is removed, the procedure is the reverse of that at the time of mounting. That is, as shown in FIG. 8, in a state where the game board is fixed, the glass door 5 is opened, and the operation bolt 72 is rotated clockwise or counterclockwise from the front of the front frame 2 with a hexagon wrench or the like.
[0063]
When the operation bolt 72 is rotated, the fixing bracket 71 is swung, and the second pressing portion 71d and the first pressing portion 71c at the tip are moved upward along an arc locus. For this reason, the pressing force applied to the second engagement side portion 61d and the first engagement side portion 61c that has been pressed by these pressing portions is loosened along with the upward movement of the pressing portion, and the rocking that has been elastically deformed. Both arm portions are displaced in the restoring direction by the elastic force stored in the arm portion 61b and the support arm portion 61a, and the second engagement side portion 61d, the first engagement side portion 61c and the like are swung upward, and FIG. It returns to the temporarily fixed posture shown in.
[0064]
Next, from this temporarily fixed posture, for example, the decorative board 21 is pulled forward by placing a finger on the game nail or the outer rail above the game board. At this time, since the lower end portion of the front surface of the decorative board 21 is locked by the locking bracket 51, the game board 20 tries to tilt forward with the locking portion as the center, and the fixing bracket 61 has the first engagement surface 41c. The first engagement side portion 61c in the engaged state is pulled forward, and the first second engagement side portion on the distal end side of the arm portion is swung upward about the fixing portion of the screw 68.
[0065]
When the lower end corner portion of the first engagement side portion 61c reaches the lead-out surface 41f beyond the upper end of the first engagement surface 41c, the lower end corner portion of the first engagement side portion 61c is the inclined lead-out surface. 11f is guided by 41f to reach the upper side portion 41b so as to slide while swinging the swinging arm portion 61b upward, passing through the upper side portion 41b and the introduction surface 41e, and the state before temporary fixing shown in FIG. become. In this state, the lower end portion of the decorative board 21 is in a temporary support posture in which the decorative plate 21 is elastically supported by the fastener 51, and the game board does not fall forward even if the front side of the game board 20 is not supported. Therefore, the operator can remove the game board 20 by grasping an appropriate position for carrying out the game board 20 with both hands and pulling the decorative plate 21 obliquely upward.
[0066]
