Is known (for example, see Patent Document 1 below).

  In this configuration, the guide rail includes a lower rail surface that guides the lower surface of the side edge portion of the tray receiving frame, and an upper rail surface that guides the upper surface of the side edge portion of the tray receiving frame facing the upper side of the lower rail surface. ing. A small gap is formed between the upper rail surface and the upper surface of the side edge of the dish receiving frame so as not to hinder smooth sliding of the dish receiving frame.

Japanese Patent Laid-Open No. 11-337087

  By the way, in the tray receiving frame, the center of gravity is located on the near side due to the influence of the load of the grill door or the like. For this reason, when the tray support frame is pulled out from the grill cabinet, the tray support frame tends to be lowered forward, and when the tray support frame in the forward-down position is pulled out, the rear upper surface of the side edge of the tray support frame is guided by the guide. Slide in a state where it is pressed against the upper rail surface of the rail.

  The bent portion of the metal wire material forming the tray receiving frame is located at the rear end of the side edge of the tray receiving frame that is in pressure contact with the upper rail surface of the guide rail. In many cases, fine irregularities are formed due to distortion such as wrinkles generated by bending the wire. For this reason, when the rear end upper surface of the side edge portion of the tray receiving frame comes into pressure contact with the upper rail surface of the guide rail, the resistance of pulling out the tray receiving frame from the grille becomes large, and smooth pulling operation is hindered. There is an inconvenience.

  In view of the above points, an object of the present invention is to provide a grill that can improve the slidability of a tray receiving frame with respect to a guide rail and can smoothly insert and remove the tray receiving frame from a grill warehouse.

  In order to achieve such an object, the present invention provides that a tray receiving frame for supporting a grill pan is housed in the grill store so as to be freely drawn out forward of the grill store, and a front surface of the grill store is provided at the front end of the tray receiving frame. A grill connected to a grill door that closes an opening, and a guide rail that guides the dish receiving frame in the front-rear direction in contact with a side edge of the dish receiving frame is provided inside the grill cabinet, The rail includes a lower rail surface that guides the lower surface of the side edge portion of the tray receiving frame, and an upper rail surface that guides the upper surface of the side edge portion of the tray receiving frame facing the upper side of the lower rail surface, The tray receiving frame is formed by bending a metal wire into a shape corresponding to the grill pan, and at least a rear end portion of the tray receiving frame has a smooth portion that is in sliding contact with the upper rail surface. It is characterized by providing a contact member That.

  According to the present invention, since the sliding contact member is interposed between the upper surface of the tray receiving frame and the upper rail surface, the bending portion of the tray receiving frame is finely deformed due to distortion such as wrinkles accompanying the bending process of the metal wire rod. Even if unevenness is formed, the contact between the unevenness and the upper rail surface can be reliably prevented. Further, since the sliding contact member includes the smooth portion, even when the tray receiving frame is put in and out, even if the front side of the tray receiving frame is inclined downward due to the influence of the load of the grill door or the like, the smoothing portion is in contact with the upper rail surface and resists. Smoothly slide with small. Thereby, the slidability at the time of putting in / out a tray receiving frame from a grill warehouse improves, and it can carry out smoothly.

  In the present invention, it is preferable that the sliding contact member includes a protruding portion that protrudes upward, and the top portion of the protruding portion is in sliding contact with the upper rail surface as the smooth portion. According to this, since the top of the projecting portion becomes the smooth portion, the contact area with the upper rail surface can be reduced, and the slidability when the tray receiving frame is taken in and out of the grill warehouse is further improved. be able to.

  More preferably, a protrusion protruding further upward is provided on the top of the protrusion of the sliding contact member, and the upper end of the protrusion is slidably contacted with the upper rail surface as the smooth portion. According to this, since the contact area to the upper rail surface can be made extremely small and the resistance when sliding to the upper rail surface can be further reduced, the sliding when the tray receiving frame is taken in and out of the grill warehouse is reduced. Mobility can be improved dramatically.

The front panels 6 on both sides thereof are provided with switches for operating the respective burner 4 and grill 3.

  As shown in FIG. 2, the grill 3 includes a grill cabinet 7 installed in the stove body 1. A grill pan 8 and a pan receiving frame 9 that supports the grill pan 8 are stored in the grill cabinet 7. Above the grill pan 8, a grill net 10 on which a food such as fish is placed is provided.

  A grill door 5 is connected to the front end of the tray receiving frame 9. A handle 11 is provided on the grill door 5 so that the finger can be pulled and pulled forward. By holding the handle 11 and pulling the grill door 5 forward, the tray receiving frame 9 is pulled out together with the grill pan 8 and the grill 10 to the front of the grill box 7.

  As shown in FIG. 3, an upper fire burner 12 is provided on the ceiling of the grill cabinet 7. In addition, overhanging portions 13 are formed on the left and right side walls of the grill cabinet 7 so as to project inwardly at a position below the grill 10, and a lower fire burner 14 is disposed on the overhanging portion 13.

  Inside the grill cabinet 7, the tray receiving frame 9 and the grill pan 8 are positioned below the lower fire burner 14 of the overhanging portion 13, and the grill 10 is positioned above the lower fire burner 14 of the overhanging portion 13. To do. Thereby, the double-sided grill which bakes the cooking material on the grill 10 with the upper fire burner 12 and the lower fire burner 14 from the upper and lower sides is comprised. In addition, what is shown by the codes | symbols 15 and 16 in FIG. 3 is the mixing pipe | tube of the upper fire burner 12 and the lower fire burner 14. In FIG.

  A guide rail 17 that is long in the front-rear direction is provided below the overhanging portion 13 inside the side wall of the grill cabinet 7 as shown in FIG. 4 with a part (bottom) of the grill cabinet 7 exposed. As shown in FIG. 3, the guide rail 17 includes a lower rail surface 18 and an upper rail surface 19 that opposes the upper portion of the lower rail surface 18, and a space between the lower rail surface 18 and the upper rail surface 19. The left and right side edges of the tray receiving frame 9 are accommodated, and the tray receiving frame 9 is pulled out and guided in the front-rear direction.

  The upper rail surface 19 and the lower rail surface 18 are not parallel, and the upper rail surface 19 extends forward with respect to the parallel line h of the lower rail surface 18 as shown in an exaggerated manner in FIG. Inclined so as to gradually approach.

  The lower rail surface 18 is formed to be longer forward than the upper rail surface 19, and a roller 20 is rotatably supported by a portion extending from the upper rail surface 19 of the front end portion of the lower rail surface 18. ing. The roller 20 is provided so that a part of the upper side thereof protrudes above the lower rail surface 18.

  As shown in FIG. 6, the tray receiving frame 9 includes a frame main body 21 having a shape corresponding to the grill pan 8, a sheet metal front support plate 22 welded to the frame main body 21 and covering the upper surface of the front end portion, And a sheet metal rear support plate 23 which is welded to the main body 21 and covers the rear end upper surface. The front support plate 22 and the rear support plate 23 are provided with net support portions 24 and 25 that support the grill net 10.

  The frame body 21 is formed by bending a metal wire into a rectangular shape corresponding to the grill pan 8. A rear end inclined portion 26 that is inclined rearward is formed on the side edge portion of the frame body 21 closer to the rear. A connecting member 27 for connecting to the grill door 5 is provided at the front end of the frame body 21.

  At both corners of the rear end of the frame main body 21, a sheet metal sliding contact member 28 formed integrally with the rear support plate 23 is provided. The slidable contact member 28 includes a protruding portion 29 that is formed by bending a mountain. Furthermore, in the present embodiment, the top of the projecting portion 29 is further protruded to provide a small projection 30 that serves as a contact point with the upper rail surface 19. In addition, reinforcing ribs 31 for maintaining the shape of the protruding portion 29 firmly are formed at the skirt portion of the protruding portion 29 and the like.

  The protruding portion 29 is formed by bending a sheet metal used as the sliding contact member 28 into a mountain fold. At this time, the top part which becomes the outer side of the fold which carried out the mountain fold will be in the state by which the sheet-metal surface was extended, and will become a smooth surface. Further, the small protrusion 30 is further extended at the top of the protrusion 29, and a smooth surface is formed at the tip of the small protrusion 30 while having a small area. In other words, the small protrusion 30 easily forms the smooth portion of the present invention having a very small sliding resistance.

  Although the sliding contact member 28 is formed integrally with the rear support plate 23 in this embodiment, it may be formed as a separate member from the rear support plate 23 and welded to the frame main body 21.

  With the above configuration, when the grill door 5 is pulled forward from the state in which the tray receiving frame 9 is stored in the grill cabinet 7, the tray receiving frame 9 moves in the pulling direction along the guide rail 17. When the pull-out amount is small, the lower surface of the frame main body 21 of the tray receiving frame 9 moves in contact with the lower rail surface 18, but the roller 20 protruding from the lower rail surface 18 rolls and guides the lower surface of the side edge of the frame main body 21. By doing so, it is pulled out smoothly with almost no resistance.

  When the pull-out amount of the tray receiving frame 9 is increased, a load directed downward is applied to the front side due to the influence of the weight of the grill door 5 and the like, and the rear end portion of the tray receiving frame 9 is moved to the upper rail surface by the stress. A load in the upward direction is applied in contact with 19. The upward load at the rear end of the tray receiving frame 9 increases as the pull-out amount increases. At this time, the top portion 30 of the projecting portion 29 formed on the sliding contact member 28 is in pressure contact with the upper rail surface 19, but the top portion 30 has a small contact area with the upper rail surface 19, and the top portion 30 is smooth. Since the formed smooth portion is formed, the dish receiving frame 9 has little resistance and smoothly slides along the upper rail surface 19. Thereby, the change of the pull-out resistance is small from the start of the pull-out to the maximum pull-out amount, and the tray receiving frame 9 can be pulled out from the grill cabinet 7 smoothly.

  Further, the upper rail surface 19 is inclined in a direction toward the front and gradually approaching the lower rail surface 18 (that is, the front end side of the upper rail surface 19 is closer to the lower rail surface 18 than the rear end side). is there). Thereby, the upper rail surface 19 acts so as to push down the rear end portion of the tray receiving frame 9 relatively as the pull-out amount of the tray receiving frame 9 increases. For this reason, the tray receiving frame 9 which is going to fall forward due to the weight of the grill door 5 is regulated by the upper rail surface 19 at the rear end side, and the front end side is lifted in the horizontal direction with the roller 20 as a fulcrum. It becomes a state.

  Therefore, the tray receiving frame 9 is pulled out in a state close to the horizontal while being prevented from being in a front-lowering posture by the action of the inclination of the upper rail surface 19. Also at this time, the top 30 of the protruding portion 29 formed on the sliding contact member 28 is in sliding contact with the upper rail surface 19, so that the feeling of resistance during the pulling out operation can be kept extremely small, and the smooth pulling out can be performed. Is done.

  As shown in FIG. 7, the rear end inclined portion 26 of the frame main body 21 is in contact with the roller 20 at the front end portion of the lower rail surface 18 in the midway state of the tray receiving frame 9 that has reached the maximum drawing amount. Thereby, in addition to the upper rail surface 19 restricting the rise of the rear end portion of the tray receiving frame 9, the roller 20 acts to lift the frame main body 21 via the rear end inclined portion 26. The tray receiving frame 9 when pulled out to the pull-out amount is in a horizontal posture or a posture that is very nearly horizontal.

  When the grill door 5 is pushed toward the grill box 7 from the state in which the dish tray frame 9 is pulled out, the dish tray frame 9 moves inward of the grill box 7 along the guide rail 17. At this time, since the tray receiving frame 9 when pulled out to the maximum drawing amount is in a horizontal posture or a very horizontal posture, the horizontal pushing force applied to the grill door 5 is applied to the tray receiving frame 9. The dish receiving frame 9 can smoothly slide along the guide rails 17 toward the inside of the grill cabinet. Also at this time, the top portion 30 of the projecting portion 29 formed on the sliding contact member 28 is in sliding contact with the upper rail surface 19, so that the resistance feeling when the tray receiving frame 9 is pushed in can be suppressed to a very low level.

  Further, since the sliding contact member 28 is made of sheet metal, the protruding portion 29 can be easily formed by performing bending processing by mountain folding. Moreover, by further providing the small protrusion 30 on the top of the projecting portion 29, the contact area is extremely small, and the surface of the sheet metal is formed to be a smooth surface, so that the sliding contact resistance is extremely small. Therefore, even higher slidability can be obtained by making the tip of the small protrusion 30 formed at the top of the projecting portion 29 formed into a mountain fold into a smooth portion.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. That is, in the above-described embodiment, the sliding contact member 28 is provided with the projecting portion 29 formed in a mountain fold, and further, a small protrusion 30 is formed on the top thereof to form a smooth portion that makes sliding contact with the upper rail surface 19 with little resistance. Although shown, it is not restricted to this shape, For example, although not shown in figure, you may comprise so that the top part of the protrusion part 29 may be slidably contacted to the upper rail surface 19 without providing the small protrusion 30. FIG. According to this, the contact area to the upper rail surface 19 where the small protrusion 30 is not provided is enlarged, but as described above, the top portion of the protruding portion 29 is formed smoothly, so that the smooth portion of the present invention can be formed. And sufficiently high slidability can be obtained.

  Further, the inclination angle of the upper rail surface 19 is appropriately set depending on the length of the guide rail 17 and the weight of the tray receiving frame 9. In some cases, the upper rail surface 19 is provided in parallel with the lower rail surface 18. Also good.

  Moreover, although the said embodiment showed what provided the roller 20 in the front-end part of the lower rail surface 18, it replaced with the roller 20 and raised the front-end part of the lower rail surface 18 in the shape of a dome, for example, and the top part was smooth. You may form the formed protrusion.

  Moreover, although the sliding contact member 28 is made of sheet metal, it may be formed of a block-shaped metal by casting instead. In this case, for example, although not shown, a block-shaped sliding member is welded and fixed to the frame main body 21, the upper surface thereof is processed smoothly to form a smooth portion, and the smooth portion slides on the upper rail surface 19. It can also be configured to touch. Furthermore, only the flat portion of the sliding contact member 28 that covers the tray receiving frame 9 may be made of sheet metal, and a protruding portion formed of block-like metal may be fixed on the upper surface thereof. According to this, a protrusion part can be made into various shapes, and is advantageous. In this case, the shape of the projecting portion may be a cone, a sharp tip, or a hemisphere, and the top may be a smooth portion.

  Moreover, the metal wire material which comprises the tray receiving frame 9 is not restricted to a circular cross section, A square cross section or a strip | belt plate shape may be sufficient.

  In the above-described embodiment, the present invention is applied to a grill incorporated in a drop-in stove. However, the present invention is similarly applied to a grill incorporated in a tabletop stove or a grill provided independently without being incorporated in a stove. The invention can be applied.
