It is formed of a fixed side portion 51e and the like, in which a mounting hole is formed, which is bent downward to extend 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 equal to or slightly smaller than the thickness of the decorative plate 21. . In addition, the upper end of the locking side 51b is gently bent toward the front to smoothly receive and guide the lower end of the decorative board 21 and prevent scratches on the decorative board surface. The locking metal member 51 is formed by molding 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 by using known processing means such as punching, bending, and press forming. To form a desired surface treatment.
[0027]
On the other hand, a receiving notch 12c is formed at a mounting position of the locking metal member 51 by cutting a rear edge portion of the lower frame portion 12 by a thickness of the locking metal member 51, and the receiving metal member 51 is mounted. The rear notch 12c receives the rear side 51c of the locking metal fitting 51 in the receiving notch 12c, and the rear end of the rear side 51c is flush with the rear end of the housing frame 10 including the left and right lower frames 12. It is to be arranged in. 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]
At the left and right ends of the lower frame 12, corner frame-shaped backing plates 12 a, 12 a are formed to connect the lower frame 12 to the left and right frames 13, 14. At the left and right corners of the side, a backing plate receiving portion 42a which is counterbored by the thickness of the backing plate portion 12a according to the shape of the backing plate portion 12a is formed. The lower edge of the decorative board 21 is cut at an angle on the back side to form a flank 42e.
[0029]
The latch 51 has a base 51a placed on the upper surface of the lower frame 12 in accordance with the position of the receiving notch 12c. The lower frame 12 is fitted to and connected to the lower frame 12 so that the lower frame 12 is sandwiched between the lower frame 12 and the fixed frame 51d.
[0030]
When the locking fitting 51 is attached in this manner, the base portion 51a is supported on the upper surface of the lower frame portion 12, and the locking side portion 51b is disposed so as to protrude upward at the front side of the lower frame portion 12. The rear end surface of the rear side portion 51b is disposed on the same plane as the rear end surface of the housing frame 10, and the locking side portion 51b has a front-rear dimension between the rear surface and the rear end surface of the housing frame 10 of the decorative board 21. It is arranged in the front-rear direction position having the same size or slightly smaller than the plate thickness.
[0031]
When the game board 20 is mounted on the locking mechanism 50 configured as described above, the left and right side edges of the decorative board 21 are viewed from the front side of the game board 20 with the glass door 5 and the upper bowl 6 open. The game board 20 is held in a slightly forwardly inclined posture by gripping the portion, and the lower end of the decorative board 21 is inserted obliquely into the housing frame 10 from above the locking side 51b.
[0032]
Here, as shown in FIGS. 3 and 4, the height of the backing plate portion 12a is formed larger than the protruding height of the locking side portion 51b. For this reason, when the lower end portion of the decorative board 21 is inserted obliquely into the housing frame, the left and right backing plate receiving portions 42a are respectively engaged with the front surfaces of the backing plate portions 12a and guided, and the decorative board 21 is directly moved downward. , The left and right locking side portions 51b can be engaged with appropriate positions on the front surface of the decorative board. Since the upper end of the locking side 51b is gently bent toward the front, the decorative board 21 slid downward is smoothly guided at its lower end to the base 51a. The side portion 51b and the base portion 51a elastically deform to receive the decorative board 21 in an inclined posture. Thereby, the game board 20 is elastically biased and supported on the base portion 51a in the forwardly inclined posture.
[0033]
Since the flank 42e is formed at the lower end of the rear surface of the decorative board 21, the lower end of the decorative board 21 can be inserted into or removed from the game board 20 in an inclined posture or swung up and down. Even if the user attaches or detaches the back set board 30 without protruding backward from the rear end face and holding the back set board 30 closed so as to be in close contact with the rear end face of the storage frame 10, excessive stress may be applied to the back set board 30 Does not occur.
[0034]
Further, the rear end side of the locking fitting 51 is bent in a U-shape to form a holding side portion 51 d, and is configured to hold the lower frame portion 12. Therefore, even if a force that tilts the locking side portion 51b forward acts and the locking side portion 51b and the base portion 51a are elastically deformed, the clamping side portion 51d transmits this force to the lower frame portion 12. And does not directly act on the fixed side portion 51e. Therefore, no excessive bending moment or tensile force acts 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 manner, the length of the elastically deformable region can be increased, and the locking mechanism that is flexible and hardly plastically deformed can be configured in a small size.
[0035]
In the embodiment, the locking side portion 51b of the locking metal is bent at a right angle 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 equal to that of the decorative plate 21. Although the form in which it projects vertically upward with substantially the same interval as the plate thickness is illustrated, the locking mechanism 50 is not limited to such a form and can lock the lower end portion of the decorative plate 21. Should be fine. For example, in the case where the same metal fitting as that of the embodiment is provided, a gap slightly larger than the thickness of the decorative board 21 is provided between the lower part of the locking side and the rear end face of the housing frame. The locking side portion 51b is positioned at a right angle to the base portion 51a with an interval slightly smaller than the thickness of the decorative board 21 between the upper side of the locking side portion and the rear end surface of the housing frame. May be bent at a small angle and projected in a slightly backward tilted posture. In the locking mechanism of such a form, even if there is a slight variation in the thickness of the decorative plate 21, the locking metal is elastically absorbed, and a gap is formed between the decorative metal and the decorative metal plate 21 or the locking metal is excessively large. No stress is generated.

[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, starting with the case where the game board 20 is mounted on the housing frame 10. Here, FIG. 11 is an explanatory view (side sectional view) showing an operation of the temporary support mechanism 60 when the game board 20 is mounted on the accommodation frame 10, and FIG. 12 is a temporary support when the game board 20 is temporarily supported. It is an explanatory view (side sectional view) showing the operation of the mechanism 60 by a solid line, and the operation of the temporary support mechanism 60 and the fixing mechanism 70 when the game board 20 is fixedly held by the two-dot chain line.
[0055]
The operator rotates the operation bolt 72 to swing and retract the fixing bracket 71 upward, and in a state where the fixing bracket 81 of the lateral fixing mechanism 80 to be described later swings and retracts upward or downward, The lower end of the decorative board 21 is obliquely inserted into the housing frame 10 using the above-described locking mechanism 50, and the game board 20 is elastically supported on the base portion 51a in the forwardly inclined posture. When the operator weakens the force in the forward tilt direction in this state, the upper part of the game board 20 swings rearward due to the elastic force of the locking metal fitting 51, and as shown in FIG. The introduction surface 41e of the upper edge engaging portion 41 is locked in a temporary support posture in which the introduction surface 41e abuts on the introduction side portion 61e of the temporary fixing member 61.
[0056]
When the operator presses the upper portion of the game board 20 backward from this state, the introduction side portion 61e is guided by the introduction surface 41e and is moved upward 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, and the entry of the decorative board 21 is allowed. When the introduction side 61e moves to the upper end of the introduction surface 41e, this time, the second engagement side 61d slides on the upper side 41d, and further moves the decorative board 21 inward of the housing frame 10. Here, a receiving groove 11e is formed in the upper frame portion 11 above the introduction side portion 61e, and is introduced when the swing arm portion 61b is swung and the introduction side portion 61e is moved upward. The side portion 61e is received and retracted so that the decorative board 21 can be smoothly attached and detached.
[0057]
When the swinging movement of the decorative board 21 into the housing frame 10 proceeds 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. Due to the force, the rear corner of the second engagement side 61d moves down so as to slide down the slope of the lead-out surface 41f, and as shown by a solid line in FIG. 12, the first engagement side 61c is moved to the first engagement surface 41c. To return to the shape before the arm portion was elastically deformed. Further, at this time, the abutment plate receiving portion 41a of the decorative board abuts on the abutment plate portion 11a, and the game board 20 is temporarily fixed in the accommodation posture accommodated in the accommodation frame 10.
[0058]
In this temporary fixing state, the first engaging side 61c of the temporary fixing member 61 and the first engaging surface of the upper edge engaging portion 41 of the decorative board are engaged at a predetermined engaging height of, for example, about 1 mm. Therefore, even if the operator releases the pressing force for pressing the decorative board 21 backward, the gaming board 20 is maintained in the storage posture in which the game board 20 is stored in the storage frame 10.
[0059]
From the front of the game board 20 temporarily fixed in this way, the operator rotates the operation bolt 72 using a hexagon wrench or the like to swing the fixing bracket 71 downward. When the fixing bracket 71 is swung, the front end side of the fixing bracket moves downward along an arc trajectory, and the curved surface area of the first pressing portion 71c that is gently bent forward is formed on the first engagement side of the locking bracket. It smoothly engages with the upper part of the portion 61c. Further, when the fixing metal 71 is swung downward, the curved surface region on the distal end side moves downward and the flat region on the base end side engages with the first engagement side portion 61c, and the first engagement side portion 61c Is pressed backward. Further, with the swing of the fixing metal 71, the second pressing portion 71d at the tip engages with the second engagement side 61d of the locking metal and presses downward, and the fixing metal 71 is further swung downward. Then, the first engagement side 61c moves down along the first support surface 41c, and presses and moves the second engagement side 61d downward while elastically deforming the support arm 61a and the swing arm 61b. .
[0060]
When the lever 71a of the fixing bracket is swung to an angular position extending in the vertical direction, the first pressing portion 71c presses the first support surface 41c rearward via the first engagement side 61c. The decorative plate 21 is sandwiched between the backing plate portion 41a and the second pressing portion 71d presses the second support surface 41d downward via the second engagement side portion 61d to be in contact with the lower frame portion 12. The game board 20 is fixedly held in the accommodation posture by sandwiching the decorative board 21 therebetween (see FIG. 8).
[0061]
When the game board 20 is fixed and held in the housing frame 10 in this manner, the backing plate portion 11a is received by the backing plate receiving portion 41a, and the rear surface of the decorative board 21 and the rear end surface of the housing frame 10 are arranged on the same plane. You. For this reason, a flat surface is formed on the back surface side of the housing frame 10, and a configuration in which compatibility with the back set board 30 closed behind is improved. The backing plate portion 11a 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 backing side of the decorative plate 21 is counterbored to form the backing plate receiving portion 41a. Therefore, the thickness of the front frame 2 including the housing frame 10 can be made 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, in a state where the game board is fixed as shown in FIG. 8, 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 distal end are moved upward along a circular locus. For this reason, the pressing force on the second engagement side 61d and the first engagement side 61c pressed by these pressing portions is loosened with the upward movement of the pressing portion, and the elastically deformed swing As a result of the elastic force stored in the arm portion 61b and the support arm portion 61a, the two arm portions are displaced in the restoring direction to swing the second engagement side portion 61d, the first engagement side portion 61c, and the like upward. It returns to the temporary fixing posture shown in FIG.
[0064]
Next, from this temporary fixing posture, the decorative board 21 is pulled forward by placing a finger on, for example, a game nail or an outer rail above the game board. At this time, since the lower end of the front surface of the decorative board 21 is locked by the locking metal fittings 51, the game board 20 tends to tilt forward about the locking metal parts, and the fixing metal fittings 61 are fixed to the first engagement surface 41c. The first engagement side 61c in the engaged state is pulled forward, and the first second engagement side on the arm tip end side swings upward about the fixing portion of the screw 68.
[0065]
When the lower end corner of the first engagement side 61c exceeds the upper end of the first engagement surface 41c and reaches the lead-out surface 41f, the lower end corner of the first engagement side 61c becomes this inclined lead-out surface. The state before the temporary fixing shown in FIG. 11 is obtained by sliding to the upper side 41b while sliding the swing arm 61b upward while being guided by 41f and tracing the upper side 41b and the introduction surface 41e. become. In this state, the lower end of the decorative board 21 is in a temporary supporting position elastically supported by the metal 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 holding the appropriate position with both hands to carry out the game board 20 and pulling out the decorative board 21 obliquely upward.
