Description

  The present invention relates to a grill provided with a grill pan that can be freely inserted into and removed from a grill cabinet.

  Conventionally, as this type of grill, a support body having a pair of left and right fixed rails arranged in the front and rear direction disposed inside or outside the grill cabinet, and a pair of left and right movables supported by both fixed rails so as to be movable in the front and rear direction. 2. Description of the Related Art There is a known slide body having a rail, in which a grill pan is put into and out of a grill cabinet in conjunction with the back and forth movement of the slide body (see, for example, Patent Documents 1, 2, and 3). According to this, a grill pan can be taken in and out smoothly, and merchantability is improved. The movable rail support system for the fixed rail includes a direct support system for directly supporting the movable rail on the fixed rail as described in Patent Document 1, and a fixed rail as described in Patent Documents 2 and 3. There is an indirect support system in which an intermediate rail to be supported is provided and a movable rail is supported by a fixed rail via the intermediate rail.

  By the way, at the time of cleaning by pulling out the grill pan, a large load may be applied to the slide body by manually pushing down the grill door attached to the front end of the grill pan or the slide body. Here, when the grill pan is pulled out, the movable rail (intermediate rail in the indirect support method) is supported only by the front of the fixed rail. When a load is applied to the slide body, the movable rail is placed at the front of the fixed rail. A bending moment is applied via the movable rail and the intermediate rail in the indirect support method. Here, conventionally, the fixed rail is fixed at a plurality of front and rear positions so that the fixed rail does not move. Therefore, when a bending moment acts on the front portion of the fixed rail, stress concentration occurs on the front portion of the fixed rail, and the fixed rail may be deformed.

  In view of the above points, an object of the present invention is to provide a grill that can prevent deformation of a fixed rail when a load is applied to a slide body.

  In order to solve the above-mentioned problems, the present invention is supported by a support body having a pair of left and right fixed rails arranged in the front-rear direction disposed inside or outside the grill cabinet, and movably supported by the two fixed rails in the front-rear direction. In the grill provided with a slide body having a pair of left and right movable rails, and the grill pan is put into and out of the grill warehouse in conjunction with the back and forth movement of the slide body, the support body is located at one location near the front end of each fixed rail The mounting portion is attached so that the tilting of the support body with the mounting portion as a fulcrum is permitted, and the support body is in contact with the rear end portion of the support body when the support body tilts by a predetermined angle. As described above, the support member is provided with a stopper member that restricts tilting backward.

  According to the present invention, when a load is applied to the slide body while the grill pan is pulled out and a bending moment is applied to the front portion of the fixed rail via the movable rail, the support body is moved back with the mounting portion of the fixed rail as a fulcrum. Tilt up. Then, when the support body tilts backward by a predetermined angle, the rear end portion of the support body comes into contact with the stopper member, and the bending moment can be received by the stopper member. Therefore, the stress due to the bending moment acts in a distributed manner over almost the entire length of the fixed rail between the mounting portion and the stopper member. As a result, stress concentration at the front portion of the fixed rail does not occur, and deformation of the fixed rail is effectively prevented.

  Further, in the present invention, when the grill pan is pulled out, the support body may tilt backward with the mounting portion as a fulcrum by the weight of the slide body including the grill pan and the grill door attached to the front end of the slide body. desirable. Here, when inserting and removing the grill pan, many people operate the grip portion of the grill door from above. For such a person, the support body tilts rearwardly upward as described above, so that the operation feeling of inserting and removing the grill pan becomes smooth. Some people lift the handle of the grill door and operate it slightly, but if the handle is lifted while the grill pan is pulled out, the support will return to the horizontal posture following this, so the feeling of operation will be improved. It will not be damaged.

  By the way, the parallelism between the pair of movable rails may cause the distance between the two movable rails to narrow backward. In this case, the movable rail comes into contact with the fixed rail in a state where the movable rail is pressed laterally by its own elastic restoring force, and as the slide body moves backward, the contact length of the movable rail with respect to the fixed rail increases. The frictional resistance due to the lateral pressing force increases, and the smoothness of putting in and out the grill pan is impaired.

  Therefore, in the present invention, it is desirable to allow lateral tilting with the mounting portion of each fixed rail as a fulcrum. According to this, even if the movable rail contacts the fixed rail in a state where the movable rail is pressed in the lateral direction due to an error in the parallelism of the pair of movable rails, the fixed rail does not move when the slide body is moved backward. It tilts in the horizontal direction in response to the lateral pressing force from the movable rail. Therefore, an increase in the frictional resistance due to the lateral pressing force can be suppressed, and smoothness of the grill pan can be secured.

  In addition, if each fixed rail is attached only at one place near the front end, the fixed rail is likely to be twisted. Therefore, it is desirable that the support body has a pair of fixed rails and a connecting member that is provided between the rear ends of the fixed rails and prevents twisting of the fixed rails. In this case, if the connecting member is connected to each fixed rail so as to have a freedom of movement in the lateral direction, even if the connecting member is provided, lateral tilting with the mounting portion of each fixed rail as a fulcrum is allowed. Thus, the effects described above can be obtained.

  In addition, conventionally, since each fixed rail is attached to the grill cabinet at a plurality of positions in the front and rear, it is difficult to remove the fixed rail, and the maintenance of the fixed rail becomes troublesome. On the other hand, in this invention, since each fixed rail is attached only by the one attachment part near the front end, removal of a fixed rail becomes easy. In particular, in the present invention, if the mounting portions of the fixed rails are detachably attached to the grill cabinet from the front, the support can be easily removed from the front of the grill cabinet, and maintenance is easy. become.

  In addition, as a method of detachably attaching the fixed rail mounting portion to the grill cabinet from the front, it is conceivable to fasten the mounting portion to the front portion of the grill cabinet from the front, but this requires a fastening operation of the mounting portion. become. Here, in the grill, generally, a frame-like window frame that covers the peripheral edge of the front opening of the grill cabinet is attached to the grill cabinet from the front. In this case, if the mounting part of each fixed rail is sandwiched between the receiving piece formed on a part of the peripheral edge of the front opening of the grill cabinet and the holding piece formed on a part of the window frame, The fastening work of the parts is not necessary, and the cost can be reduced by reducing the number of assembly steps. Further, by removing the window frame, the holding of each fixed rail is released, and the support body can be easily removed.

The grill door 5 that closes the front opening of the grill cabinet 1 is in contact with the window frame 14 from the front. A claw piece 141 is formed on the lower side of the window frame 14, and the window frame 14 is engaged with the claw piece 141 in a locking hole formed on the front edge of the bottom plate of the grill cabinet 1. Is fastened to the grill 1 from the front.

  A support body 6 having a pair of left and right fixed rails 61 and 61 that are long in the front-rear direction is disposed below the inside of the grill cabinet 1. Further, a slide body 7 having a pair of left and right movable rails 71, 71 supported on the fixed rails 61, 61 so as to be movable in the front-rear direction is provided, and the grill pan 1 is connected to the grill cabinet 1 in conjunction with the forward-backward movement of the slide body 7. 2 is taken in and out.

  4 and 5, the slide body 7 is fixed to the pair of movable rails 71, 71, the horizontal bar portion 72 between the front ends of the movable rails 71, 71, and the front surface of the horizontal bar portion 72. And a door mounting frame 73 for mounting the grill door 5 and a pair of left and right tray support frames 74 and 74 for supporting the grill pan 2. Both the movable rails 71 and 71 and the horizontal bar portion 72 are formed by bending one bar. That is, the bar is bent backward at the left and right ends of the horizontal bar portion 72 to form both movable rails 71, 71. Further, a pin 711 protruding inward in the lateral direction is planted in a portion near the rear end of each movable rail 71. A U-shaped hook portion 741 opening forward is formed at the rear end portion of each dish support frame 74. The front end portion of each dish support frame 74 is connected to the horizontal bar portion 72 in a state where the hook portion 741 is engaged with a groove 712 formed on the outer peripheral surface of the pin 711 from the rear. A gap for avoiding interference with the fixed rail 61 is secured between each movable rail 71 and each dish support frame 74.

  When a finger is applied to the handle 51 of the grill door 5 from below and pulled forward, the slide body 7 is guided by the fixed rail 61 and moves forward, and the grill pan 2 is moved together with the slide body 7 to the front of the grill cabinet 1. Pulled out. When the grill door 5 is pushed backward, the slide body 7 is guided by the fixed rail 61 and moves rearward, and the grill pan 2 is stored in the grill cabinet 1 together with the slide body 7.

  The support body 6 includes the pair of fixed rails 61 and 61 and a connecting member 62 provided horizontally between the rear ends of the fixed rails 61 and 61. Each fixed rail 61 is composed of an outer rail 63 having a U-shaped cross section and an inner rail 64 having a U-shaped cross section that is housed in the outer rail 63, and between the outer rail 63 and the inner rail 64. The movable rail 71 is slidably inserted in the front-rear direction into the secured gap. On the laterally inner side surface of the outer rail 63, a longitudinal guide hole 631 is formed in the front-rear direction through which the pin 711 planted in each movable rail 71 is inserted. The forward stroke end position of the slide body 7 (movable rail 71) is regulated by the contact of the pin 711 with the front end of the guide hole 631.

  It is possible to mount a direct acting ball bearing on each fixed rail 61 and to support each movable rail 71 on each fixed rail 61 via the ball bearing so as to be movable back and forth. Become. Therefore, in this embodiment, the movable rail 71 is in direct contact with the fixed rail 61 so as to be slidably supported. In this case, if the fixed rail 71 is made of stainless steel and the movable rail 71 is plated, the stick-slip phenomenon (repeated by being caught or slid during sliding) is unlikely to occur even if the sliding portion is broken. Become.

  As shown in FIG. 2, each fixed rail 61 is placed on a longitudinally receiving base 15 installed in each of the left and right sides on the bottom plate of the grill cabinet 1. The support body 6 is attached to the grill cabinet 1 at one attachment portion 61a near the front end of each fixed rail 6 so that upward tilting with the attachment portion 61a as a fulcrum is allowed.

  Specifically, at the front end of the outer rail 63 of each fixed rail 61, a tongue-shaped attachment portion 61a that is bent outward in the lateral direction is formed. Further, as shown in FIGS. 6 and 7, a recessed portion 16a for receiving the mounting portion 61a is formed in a part of the peripheral edge of the front opening of the grill cabinet 1, that is, in the lower portion of the front edge of the side wall portion of the grill cabinet 1. Thus, a tongue-shaped receiving piece 16 bent outward in the lateral direction is formed at the rear end portion of the recessed portion 16a. Further, a pressing piece 142 that faces the front surface of the receiving piece 16 is formed at the lower part of each of the left and right sides of the window frame 14. The attachment portion 61 a is sandwiched between the receiving piece 16 and the pressing piece 142. In the present embodiment, the presser piece 142 is in contact with only a part of the lower portion of the attachment portion 61a in the lateral direction. Accordingly, each fixed rail 61 is easily tilted rearward and laterally inward with the mounting portion 61a as a fulcrum. Then, when the slide body 7 is moved to the forward stroke end position and the grill pan 2 is pulled out, the support body 6 (fixed rail 61) tilts backward by the weight of the slide body 7 including the grill pan 2 and the grill door 5. Like to do.

  A stopper member 17 is provided at the rear end portion of the grill cabinet 1 so as to be positioned below the exhaust duct 11 and receive the rear end portion of the support 6 as shown in FIGS. The stopper member 17 includes an upper plate portion 171 facing the upper surface of the rear end portion of the support 6, that is, the upper surface of the rear end portion of the fixed rail 61 and the upper surface of the connecting member 62 with a gap. Then, when the support body 6 tilts backward by a predetermined angle with the mounting portion 61a as a fulcrum, the convex portion 621 formed on the upper surface of the connecting member 62 comes into contact with the upper plate portion 171 and more than that of the support body 6. Back tilt is limited.

  As shown in FIG. 3, the stopper member 17 is a downward bulging portion formed at a part of the lower surface of the exhaust duct 11 at a flange portion 173 bent at the upper end of the rising portion 172 at the front end of the upper plate portion 171. 111 is fastened. Further, as shown in FIG. 6, the side plate portions 174 on the left and right sides of the rising portion 172 are fastened to the side walls on the left and right sides of the grill cabinet 1. Further, as shown in FIGS. 1 and 2, a protruding portion 175 projecting outward in the lateral direction is formed at the rear end portion of each of the left and right side edges of the upper plate portion 171, and the rear end of the side wall portion of the grill cabinet 1. A receiving portion 18 that receives the overhanging portion 175 is bent at the portion, and the overhanging portion 175 is fastened to the receiving portion 18.

  The connecting member 62 is connected to each fixed rail 61 so as to have a freedom of movement in the lateral direction. Specifically, as shown in FIGS. 5 and 8, a first hole 622 and a second hole 623 positioned inward in the lateral direction are formed at the left and right ends of the connecting member 62. ing. Then, the stepped screw 624 inserted through the first hole 622 is screwed into the screw hole 632 formed at the rear end of the outer rail 63 of the fixed rail 61, and the connecting member 62 is connected to the rear end of the fixed rail 61. is doing. Further, a claw portion 633 that extends inward in the lateral direction and bends backward is formed at the rear end of the outer rail 63 of the fixed rail 61, and this claw portion 633 is engaged with the second hole 623 to fix the fixed rail. 61 is prevented from being twisted. Here, the 1st hole 622 is formed so that it may have a play of a horizontal direction between the axial part of the stepped screw 624 inserted in this, and the 2nd hole 623 is also a nail | claw which engages with this It is formed so as to have a lateral play with the part 633. Therefore, the connecting member 62 is connected to each fixed rail 61 so as to have a freedom of movement in the lateral direction. As a result, even if the connecting member 62 is provided, tilting inward in the lateral direction with the mounting portion 61a of each fixed rail 61 as a fulcrum is allowed.

  According to the present embodiment, when the slide body 7 is moved to the forward stroke end position and the grill pan 2 is pulled out to the front of the grill cabinet 1, the support body 6 is tilted backward with the mounting portion 61a as a fulcrum, The rear end portion of the support 6 (the convex portion 621 on the upper surface of the connecting member 62) comes into contact with the stopper member 17. In this state, if a large load is applied to the slide body 7 by manually pushing the grill pan 2 or the grill door 5 downward, a large bending moment acts on the front portion of the fixed rail 61 via the movable rail 71. The bending moment is received by the stopper member 17 that contacts the rear end portion of the support 6. Therefore, the stress due to the bending moment acts in a distributed manner over the entire length of the fixed rail 61 between the mounting portion 61 a and the stopper member 17. As a result, stress concentration at the front portion of the fixed rail 61 does not occur, and deformation of the fixed rail 61 is effectively prevented.

  Further, the tilting of the support 6 in the state where the grill pan 2 is pulled out has the following advantages. That is, many people operate the handle 51 of the grill door 5 from above when the grill pan 2 is put in and out, and for such a person, the support 6 tilts backward as described above. The operation feeling when putting in and out the grill pan 2 becomes smooth. Some people operate the handle 51 of the grill door 5 by lifting it, but if the handle 51 is lifted with the grill pan 2 pulled out, the support 6 returns to the horizontal posture following this. Therefore, the operational feeling is not impaired.

  By the way, when the pair of movable rails 71 and 71 are formed by bending both ends of the horizontal bar portion 72 backward, the angle with respect to the horizontal bar portion 72 is an acute angle slightly smaller than 90 ° in consideration of the spring back. The movable rail 71 is bent. Therefore, if the amount of sprigback is small, the two movable rails 71 and 71 are not parallel, and the distance between the two movable rails 71 and 71 may become narrower toward the rear. In this case, the movable rail 71 comes into contact with the fixed rail 61 while being pressed inward in the lateral direction by its own elastic restoring force. If the fixed rail 61 is immovable in the lateral direction, the frictional resistance due to the lateral pressing force increases as the contact length of the movable rail 71 with respect to the fixed rail 61 increases as the slide body 7 moves rearward. And the smoothness of taking in and out of the grill pan 2 is impaired.

  On the other hand, in the present embodiment, since the fixed rail 61 with the mounting portion 61a as a fulcrum is allowed to tilt inward in the lateral direction, the movable rail 71 is pressed laterally inward with respect to the fixed rail 61. Even if it contacts, when the slide body 7 is moved backward, the fixed rail 61 receives the lateral pressing force from the movable rail 71 and tilts inward in the lateral direction. As a result, an increase in frictional resistance due to the lateral pressing force is suppressed, and smoothness in and out of the grill pan 2 can be ensured.

  Here, the tilting of the fixed rail 61 outward in the lateral direction is not allowed because the fixed rail 61 abuts against the side wall portion of the grill 1, and the interval between the two movable rails 71 and 71 becomes wider toward the rear. In case it cannot be dealt with. Therefore, when the movable rails 71 and 71 are formed, even if the bending angle of the movable rail 71 with respect to the horizontal bar portion 72 increases the springback amount, the distance between the movable rails 71 and 71 increases toward the rear. It is set so that there is nothing. It should be noted that a gap is provided between the side wall portion of the grill cabinet 1 and the fixed rail 61 so that the fixed rail 61 is allowed to tilt laterally outward, or the inner rail 64 is moved in front of the outer rail 63. It is also possible to suppress the increase in the frictional resistance when the distance between the movable rails 71 and 71 is widened toward the rear by providing only in the portion.

  In addition, when the grill is used to some extent, the fixed rail 61 and the movable rail 71 become dirty and the slidability deteriorates. In this case, it is necessary to remove the support 6 from the grill 1 and perform maintenance such as cleaning of the fixed rail 61. Here, if the fixed rail 61 is attached to the grill cabinet 1 at a plurality of positions in the front and rear, it becomes difficult to remove the fixed rail 61 and the maintenance becomes troublesome. On the other hand, in this embodiment, when the window frame 14 is removed from the front surface of the grill cabinet 1, the holding portion 61a held by the holding piece 142 formed on the window frame 14 is released, and the support 6 is taken out from the grill cabinet 1. be able to. As described above, since the support 6 can be easily removed, the maintainability is improved.

  In addition, in order to improve maintainability, the attachment part 61a should just be attached to the grill warehouse 1 so that attachment or detachment is possible from the front, and as an example other than this embodiment, an attachment part is attached to the receiving piece 16 formed in the grill warehouse 1. It is conceivable to fasten 61a with a screw from the front. However, this requires a fastening operation of the mounting portion 61a during assembly. On the other hand, in this embodiment, the fastening operation of the attachment portion 61a is not necessary, and it is advantageous in that the cost can be reduced by reducing the number of assembly steps.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above-described embodiment, a direct support system in which the movable rail 71 is directly supported by the fixed rail 61 is adopted. However, an intermediate rail that is supported by the fixed rail so as to be movable in the front-rear direction is provided. It is also possible to adopt a method in which the movable rail is supported so as to be movable in the front-rear direction, that is, an indirect support method in which the movable rail is supported on the fixed rail via the intermediate rail. Here, in the direct support method, the portion near the front end of the fixed rail 61 provided with the mounting portion 61a is positioned in front of the rear end of the movable rail 71 in a state where the slide body 7 is moved to the forward stroke end position. In the indirect support method, it may be a location that is located forward of the rear end of the intermediate rail at the forward stroke end position of the slide body.

  Moreover, in the said embodiment, although the fixed rail 61 is arrange | positioned inside the grill warehouse 1, it is also possible to arrange a fixed rail outside the grill warehouse. In this case, a mounting portion provided at a location near the front end of the fixed rail may be attached to a bracket fixed to the stove body, and a stopper member that restricts tilting of the support from the rear side may be fixed to the stove body. Moreover, although the said embodiment applies this invention to the grill built in a gas stove, this invention is applicable similarly to the grill provided independently, without incorporating in a gas stove.
