Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing device for a grill door such as a grill incorporated in a gas table stove.

[0002]

[Prior art]

 As a device for opening and closing a grill door that opens and closes by opening and closing the grill door as the grill plate is put in and taken out, there is a conventional device, for example, Japanese Utility Model Publication No. 2-48709 (hereinafter referred to as conventional example 1) or Some are disclosed in Japanese Utility Model Publication No. 1-100017 (hereinafter referred to as Conventional Example 2) and the like.

In the conventional example 1 disclosed above, a door open rod is obliquely rearwardly and upwardly installed in a bow-like manner integrally with the tip of a slide rod that is interlocked with a water tray by an opening spring, and when the water tray is pulled out. , When the stop spring is unlocked, the pressing force of the opening spring causes the integral slide rod and door open rod to slide forward, pushing the water tray forward and simultaneously pushing up the grill door with the door open rod to rotate it. It has a structure that can be pushed open to the fully open position.

Further, as shown in FIGS. 1 and 2, the prior art example 2 discloses an arm fixed to the inside of the door body with a predetermined distance and a water container. A cam connected to the handle of the plate is provided in association therewith, and as the cam moves outward in conjunction with the handle, the arm is pushed to swing the door body to the open position.

[0005]

[Problems to be solved by the device]

 In the conventional example 1 of the above-mentioned conventional technique, when the integral slide rod and the door open rod are moved forward by a certain stroke from the housed state by the opening spring, the grill door is pushed open by the door open rod and the pivot point is used as a fulcrum. Is rotated counterclockwise in the figure and opened. Then, when the slide rod and the door open rod are pushed rearward from the open state, as the door open rod retracts backward, its lifting hold is released and the door open rod is rotated clockwise in the figure by its own weight to be closed.

[0006] Therefore, when the water tray is pulled out, the door open rod pops out to the front of the grill body together with the slide rod, and these interfere with the return of the food to be cooked, making it difficult to perform the work. It was inconvenient to use in actual use, such as when people could touch it and get burned. In addition, since the grill door is pushed open by the door open rod, its operation cannot be performed lightly due to the frictional resistance between the grill door and the door open rod, and it is lacking in certainty and inferior in durability. There was a point.

Further, in Conventional Example 2, as the cam moves outward in conjunction with the handle when the water tray is pulled out, the tip of the arm is pushed outward by the cam, and the door body integrated with this is pushed. The door is pushed open to the open position via the arm and the door body is closed via the arm when the water tray is stored, which is the reverse of the operation when the water tray is pulled out.

Therefore, in Conventional Example 2, since the door body is opened and closed only by the contact operation in which the arm makes a circular motion with respect to the horizontal motion of the cam, the holding operation at the open position of the door body by the arm causes the cam and the arm to move. Not only did the frictional resistance remarkably increase and the operability was difficult, the operation was not reliable, and there was a problem in terms of durability.

In view of the problems of the prior art, the present invention has a light and reliable opening and closing of the grill door as the grill plate is put in and taken out, and is easy to use, and is easy to operate and secure. The purpose is to provide a grill door opening / closing device with excellent durability.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, a grill door opening / closing device of the present invention comprises a grill door which is provided in an opening on the front surface of a grill cabinet and which vertically rotates about a support shaft as a fulcrum to open and close in a single-opening manner. In a grill door opening / closing device including a grill plate that slides in and out of the grill chamber and a interlocking device that opens and closes the grill door when the grill plate is in and out, the interlocking device between the grill plate and the grill door is , The tip of which is pivotally supported by a pivot portion at a position different from the pivot of the grill door, and the base end of which extends from the pivot portion in the depth direction of the grill through a connecting member which is detachably associated with the grill plate. The feature is that the forward and backward movement of the grill plate is converted into rotational movement of the grill door and transmitted.

Further, it is characterized in that it is provided with a biasing means for biasing the grill door in the opening direction.

[0012]

[Action]

 Since the grill door opening / closing device of the present invention has the above-mentioned configuration, when the grill pan is pulled out from the stored state to the front, the connecting member associated with the grill pan pushes the grill door forward at the pivotal portion, and the grill door is opened. Is rotated upward about the spindle to be released. At this time, if the grill door is urged in the opening direction by the urging means, the grill door is rotated upward in synchronization with the movement of the grill plate by the urging force of the urging means and is held in the open state. After that, only the grill plate is pulled out by itself.

When storing the grill plate, when the grill plate is pushed into the grill cabinet, the connecting member is pushed rearward, whereby the grill door is pulled at the pivotal support portion and moves downward around the support shaft. Rotate and close.

[0014]

【Example】

 An embodiment of a grill door opening / closing device according to the present invention will be described below with reference to the drawings.

The embodiment is applied to a grill built in a gas table stove. In FIG. 1 and FIG. 4, 1 is a grill pan, and guide rails provided on both sides of the bottom wall 5 a of the grill storage 5 are provided. It is slid along 6 so that it can be easily stored in and removed from the grill case 5 through the front opening 7.

A handle 8 is integrally fixed to the front part of the grill plate 1 via a mounting plate 9, and a grill 10 is placed in the grill plate 1 in a detachable manner.

Reference numeral 2 denotes a grille door, which is pivotally mounted on a front opening 7 of the grill case 5 by a support shaft 11. The grille door 2 pivots about the support shaft 11 as a fulcrum in a vertically openable manner at a constant angle. You can do it.

When the grill door 2 is fully closed (when the grill plate 1 is stored), the lower end portion 2a of the grill door 2 is engaged with the projecting plate 8a provided on the handle 8 to open the front opening 7 of the grill cabinet 5. When the grill door 2 is fully opened (when the grill plate 1 is pulled out), it is closed so that there is no gap, and the engagement is released so that the grill door 2 can be opened without any hindrance. (See Figure 1).

Reference numeral 3 denotes a connecting member for interlocking the grill plate 1 and the grill door 2 with a certain forward / backward stroke a and opening / closing the grill door 2 as the grill plate is taken in and out. As shown in the drawing, the tip short shaft portion 3a is inserted into the tip shaft hole 12a of the arm rod 12 fixed to the inside and outside of the grill door 2 with the connecting rod formed in a planar U-shape. The portion 3a is pivotally supported at a position different from the spindle 11 of the grill door 2, and the base end connecting portion 3b extending from the pivotal portion in the depth direction of the grill has a slide hole 13 formed in the side wall 5b of the grill case 5. Is attached to the rear face portion 1a of the grill plate 1 so as to be in contact with the rear face portion 1a.

The slide hole 13 guides the forward / backward movement of the base end connecting portion 3 b of the connecting rod 3 and the movement of the connecting rod 3 in the front-rear direction by an amount less than or equal to half the length of the grill plate 1 in the depth direction. That is, this is for restricting to a constant short forward / backward stroke a, and in this forward / backward stroke a, the grill plate 1 and the grill door 2 are located at different positions from the spindle 11 of the grill door 2. The tip short shaft portion 3a is interlocked via the pivotally supported connecting rod 3, and the forward / backward movement of the grill plate 1 is transmitted to the grill door 2 by changing it into a rotary motion, so that the grill door 2 is moved to the short side of the grill plate 1. It is configured to be fully opened (substantially horizontal position) and fully closed (substantially vertical position) with the paddle advancing / retreating stroke a.

Note that the regulation of the fully open position and the fully closed position of the grill door 2 is replaced with the one that regulates a constant forward / backward movement stroke a of the connecting rod 3 by the slide hole 13 of the embodiment, and the rotation angle of the grill door 2 is changed. The advancing / retreating stroke of the connecting rod 3 may be regulated by regulating the degree to a constant angle. Then, the opening degree of the grill door can be changed by selecting the regulation stroke a within the range of a fixed pull-out amount.

Reference numeral 4 denotes an urging means for pushing the grill door 2 upward when the grill door 2 is opened and holding the grill door 2 in the open position, which uses a tension spring to prevent heat corrosion. For this purpose, the base end connecting portion 3b of the connecting rod 3 and the hooking piece 14 provided on the side wall 5b of the grill case 5 are provided outside the grill case 5, that is, between the side wall 5b of the grill case 5 and the partition wall 21. Both ends are arranged so as to be hooked, and the grill door 2 is biased in the opening direction through the connecting rod 3 by the pulling force of the pulling bar 4.

As the urging means, a compression spring is used instead of the tension spring 4 of the embodiment, and the compression spring is provided between the base end connecting portion 3b of the connecting rod 3 and the back wall 5c of the grill case 5. Alternatively, a torsion spring may be provided on the spindle 11 of the grill door 2 to bias the grill door in the opening direction by its repulsive force.

The spring force of the tension spring 4 may be a pushing force for rotating the grill door 2 upward when the grill door 2 is opened. Therefore, when the grill plate 1 is stored in the grill cabinet 5, there is sufficient spring force to hold the grill plate 1 so that it does not move forward only by the frictional resistance between the grill plate 1 and the guide rail 6. Since it is sufficient, it is not necessary to provide a special stopper for preventing the movement of the grill pan 1 forward by the spring force. However, it goes without saying that a stopper 20 as shown in FIGS. 1 and 2 may be provided to maintain the certainty.

In the figure, 15 is a grill burner, 16 is an exhaust passage, 17 is an exhaust port, 18 is a gas table stove, and 19 is a cooking pot.

In the above-mentioned configuration, when the grill plate 1 is stored in the grill cabinet 5, the grill door 2 is in the closed position and the pulling spring 4 causes the opening direction (clockwise direction in the drawing) via the connecting rod 3. In addition, the grill plate 1 is also biased in the forward direction (left direction in the drawing) by the pulling bar 4 (see the solid line in FIG. 1).

Therefore, when the user holds the handle 8 from this stored state to overcome the frictional resistance of the grill plate 1 with the guide rail 6 (or unlocks the stopper 20) and pulls the grill plate 1 forward, the tension spring 4 is pulled. The connecting rod 3 and the grill plate 1, which are pulled forward by, move together as a unit, and the grill door 2 is moved from the connecting rod 3 to the pivot 11 as a fulcrum. Rotate upward (clockwise in the figure) at the pivot. At this time, the lower end portion 2a of the grill door 2 and the projecting plate 8a of the handle 8 are smoothly disengaged, and the pulling force of the grill plate 1 is reduced by the pressing force of the pulling bar 4.

When the grill plate 1 is pulled out by a constant short forward stroke a regulated by the slide hole 13, the grill door 2 is rotated to a substantially horizontal fully opened state, and the grill door 2 by the connecting rod 3 is rotated. The rotation of the grill door 2 is stopped, and thereafter the grill door 2 is held in the open position by the pulling force of the pulling bar 4 (see the state of the chain line in FIG. 1).

Subsequently, when the grill plate 1 is pulled out forward, only the grill plate 1 is pulled out while the grill door 2 is kept in the open position (see the state shown by the solid line in FIG. 2), and the grill plate 1 is opened in the grill case 5. It can be pulled out and escaped.

Next, when the grill pan 1 is stored in the grill pan 5, the rear part of the grill pan 1 is placed on the guide rail 6 of the bottom wall 5 a of the grill pan 5 and pushed in backward, Moves backward along the guide rail 6.

When the grill tray 1 reaches a certain retracted stroke a at the end of storage, the back surface portion 1 a of the grill tray 1 is locked to the front end of the slide hole 13 and is on standby. 3b, and thereafter, the grill plate 1 and the connecting rod 3 are united as a unit to move rearwardly against the elastic spring 4.

While the grill plate 1 is retracted by a fixed short retract stroke a regulated by the slide hole 13, the grill door 2 is pulled by the connecting rod 3 so that the grill door 2 extends from a substantially horizontal fully open state to a substantially vertical fully open state. At the same time as it is rotated counterclockwise in the drawing to the closed state and closed, the grill plate 1 applies a constant tensile force to the spring 4 and friction resistance with the guide rail 6 or locking by the stopper 20 causes the grill plate 1 to reach a predetermined storage position. And the lower end 2a of the grill door 2 is engaged with the projecting plate 8a of the handle 8 to securely close the front opening 7 of the grill case 5 (see the solid line in FIG. 1).

In this way, when the grill plate 1 is put in and taken out of the grill cabinet 5, the movement of the connecting rod 3 is short and constant during the forward / backward stroke a in which the grill door 2 is fully closed to fully open and fully opened to fully closed. It is regulated by the forward stroke, and the grill door 2 is automatically opened / closed by pivoting in a single opening in the regulation range. Therefore, since the grill door 2 is fully opened by simply pulling the grill plate 1 a little, it is possible to easily confirm the cooking condition of the food such as fish.

[Effect of device]

 As described above, the device for opening and closing the grill door of the present invention automatically connects the grill door with the connecting member when the grill tray is pulled forward from the stored state or when the grill tray is stored. Fully open or fully closed. Therefore, the opening and closing of the grill is easy and reliable as the grill is taken in and out, which is convenient and easy to operate. Further, since the connecting member extends in the depth direction of the grill from the grill door, it is safe because it does not get in the way and does not burn when touched.

Further, since the structure is simple and the operation is smooth, there is no failure and the durability is excellent.

Further, if the urging means for urging the grill door in the opening direction is provided, the grill door automatically opens when the grill plate is pulled out, and the grill door can be surely held open. The operation of putting in and out the grill plate can be done easily when returning items.
