Description

  The present invention relates to an attachable / detachable gotok particularly suitable for a burner used outdoors and a method for storing the same.

  Gotok is one of the components of the burner, and supports the cooking utensils such as pans stably while separating the cooking utensils from the flame holes by a predetermined distance to efficiently heat the cooking utensils. Is. In order to stably perform this support, it is ideal to use a large iron that can support a wide area of the bottom surface of the cooking utensil. On the other hand, a burner whose main purpose is to be used outdoors such as camping is required to have a high portability so that it can store a gotok as compactly as possible. Ensuring support stability of cooking utensils and improving portability are conflicting issues.

  In order to solve this conflicting problem, for example, in Patent Document 1, two plate-like members are assembled into a cross to form a gotok and attached to the main body of the burner. There is disclosed a detachable gotok that is detached from a main body and can be carried in a state of being disassembled into plate-like members. By using the structure that can be assembled and disassembled in this way, it can be used as a stable gotok that supports a wide area of the bottom of the cooking utensil when in use, while each plate-like member of this gotok is stored compactly when not in use. And good portability can be secured.

Japanese Patent Laid-Open No. 9-229381

  The Gotoku described in Patent Document 1 is a combination of a plurality of separated parts, which are simply combined in a cross by fitting each other into a slit formed in each part, and each part is not firmly fixed. The parts are relatively easy to rotate around the combined part. For this reason, when the load applied to the gotok becomes uneven when placing the cookware, or when a burner is installed on an inclined ground, rotation occurs between the combined parts, and the cookware is supported by the gotok. The condition tends to become unstable.

  In addition, it must be attached to the burner while maintaining the combined state of multiple parts, requiring work, and especially when used outdoors, the larger the number of parts, the more it gets mixed in with other luggage and it is missing There is a problem that it is easy to become, and its management needs attention.

  Accordingly, an object of the present invention is to ensure the support stability of a cooking utensil with a gotok that is detachably attached to a burner, and to be able to handle the gotok easily.

  In order to solve the above-described problem, the present invention includes a first opening / closing piece and a second opening / closing piece continuously connected to the first opening / closing piece, the first opening / closing piece and the second opening / closing piece. A mounting part for mounting the cooking utensil and a receiving part for receiving the burner are formed on the piece, and the opening and closing pieces are opened to each other and fixed in a state where the burner is received in the receiving part when used. In this way, a removable bottling was constructed.

  This detachable gotok consists of a single part in which the first opening and closing piece and the second opening and closing piece are connected in series, and since it is not a type that combines multiple separated parts at the time of use, the gap between both opening and closing pieces It is hard to cause sticking. For this reason, the supporting stability of the cooking utensil placed on the detachable gotok is high, and the cooking operation can be performed safely. In addition, since it is only necessary to open both opening and closing pieces, compared to combining multiple separated parts, the work of attaching and detaching the bar to the burner is very simple and the parts can be easily managed. is there.

  The fixing of the gotok to the burner has various configurations such as a method in which the main body of the burner is directly sandwiched by the receiving portion, an attached member such as a windshield attached to the burner, or a method in which a dedicated member for attaching the gotok is sandwiched by the receiving portion. Can be adopted. Further, in the above, “the state in which the burners are received in both receiving portions” means not only the state in which the entire burner body is housed inside the receiving portions, but also a part or all of the burner main body. It includes a state of being located above the upper end or below the lower end. Furthermore, in these configurations, it is possible to form recesses in both the opening and closing pieces and to sandwich the intake pipe of the burner in these recesses. In this way, the state of fixing the bar to the burner can be further ensured.

  In the above configuration, the first opening and closing piece and the second opening and closing piece are elastically connected so as to form a leaf spring, and the opening and closing pieces are opened against the biasing force during the use. It is more preferable that a burner is received in both receiving portions.

  Thus, by providing spring elasticity to both the opening and closing pieces, the strength characteristics of the deformation against deformation are improved. For this reason, even if both the opening and closing pieces are thinned, the predetermined strength (strength enough to stably support the cooking utensil) can be maintained, and further weight reduction of the detachable iron bar can be achieved. Furthermore, it is possible to reliably prevent the sticking from falling off the burner by providing a retaining piece or the like for retaining the burner on both the opening and closing pieces.

  In the configuration in which both the opening and closing pieces are elastically connected, it is more preferable that the fixing to the burner is performed by the urging force.

  As described above, if the detachable iron plate is fixed by the urging force of both the opening and closing pieces, a fixing member is unnecessary. For this reason, while being able to make the structure simple, the attachment / detachment operation | work can be performed rapidly.

  Further, in the configuration in which the first opening / closing piece and the second opening / closing piece are elastically connected, the first opening / closing piece and the second opening / closing piece are predetermined in a state in which no external force is applied to the both opening / closing pieces. The predetermined opening angle is the same as or smaller than the opening angle of the two open / close pieces when the burner is fixed to the receiving portions. Is more preferable.

  When attaching the detachable gotok to the burner, the burner is attached to the gap between the opening and closing pieces. If the gap is closed, the burner must be held with one hand and the gap with the other hand widened. It is difficult to work. Therefore, in the state where no external force is acting on both opening and closing pieces, if the opening and closing pieces are opened from each other by a predetermined angle and a gap is secured in advance, the burner can be attached smoothly and work can be performed. Efficiency is greatly increased. Here, when the predetermined angle is larger than the opening angle of the both opening and closing pieces when the burner is received and fixed to the both receiving portions (if the gap is too wide), the detachable gotok may be fixed to the burner. Can not. For this reason, the predetermined angle must be the same as or smaller than the opening angle of the opening and closing pieces when the burners are received and fixed to the receiving portions.

  In each of the above-described configurations, it is more preferable that when the burner is not used, it is removed from the burner and then the opening and closing pieces are closed so as to approach each other.

  Thus, if both the opening and closing pieces can be closed and stored, the size can be reduced and portability is improved.

  In the configuration in which both the opening and closing pieces can be closed and stored, at least one of the opening and closing pieces is formed with a locking piece that keeps the opening and closing pieces closed, and the both opening and closing pieces are opened when not in use. It is more preferable that the opening and closing pieces are locked by the locking pieces when the pieces are closed.

  Thus, if both the opening and closing pieces are closed and locked by the locking pieces, the possibility of the both opening and closing pieces being inadvertently opened during the carrying of the detachable gotok is low, and the portability is further improved. .

  In each of the above-described configurations, the mounting portion of the both opening and closing pieces rotates around the rotation shaft provided on the both opening and closing pieces so that the opening and closing pieces can be stored toward the center. More preferred.

  In this way, by allowing the mounting portion to be stored, the size of the detachable gotok during storage can be further reduced, and the portability at the time of outdoor or the like is further improved. The rotation direction is not particularly limited, but it is more preferable that the rotation direction is stored by rotating upward around the horizontal rotation axis from the use state. In this way, the placing portion is pressed downward by the load of the cooking utensil placed on the placing portion, and the placing portion is inadvertently stored and in use while the detachable iron is used. Can be prevented. For this reason, the high safety | security of this detachable type | mold is ensured.

  In addition, instead of elastically connecting the two open / close pieces so as to form a leaf spring as described above, a vertical rotation that relatively rotates the open / close pieces at the longitudinal center of the open / close pieces. While providing a moving shaft and an urging member interposed between the two opening and closing pieces, when not in use, the urging force of the urging member closes the opening and closing pieces so that they are not orthogonal to each other. It is also possible to adopt a configuration in which a burner is received in both receiving portions in a state where both the opening and closing pieces are opened in a cross shape against the urging force.

  When the first opening / closing piece and the second opening / closing piece are elastically connected so as to constitute a leaf spring, the connecting position is usually the end of each opening / closing piece. In many cases, the support mode of the instrument must be three-point support. On the other hand, when the vertical rotation shaft is provided as described above, both the opening and closing pieces can be opened in a cross shape by the vertical rotation shaft, and the support mode of the cooking utensil can be set to four-point support. it can. In this way, by supporting four points, particularly when a load of a heavy cooking utensil is placed, the load is dispersed to the four placement portions, and the placement portion is prevented from being deformed by the load. it can. Also, since the support interval when supporting at 4 points (for example, an equal interval of 90 degrees) is smaller than the support interval when supporting at 3 points (for example, an equal interval of 120 degrees), The cooking utensil is difficult to tilt in a specific direction, and this cooking utensil can be supported more stably.

  In addition, if the both open / close pieces are closed by the urging force of the urging member to fix the detachable iron, no fixing member is required. For this reason, while being able to make the structure simple, the attachment / detachment operation | work can be performed rapidly.

  In the configuration in which the urging member is provided, the mounting portion of the both opening / closing pieces can be rotated around the rotation shaft provided in the both opening / closing pieces and stored toward the center of the both opening / closing pieces. It is more preferable to do so.

  In this case as well, as described above, the storage size of the detachable gotok can be reduced and the portability can be improved.

  Further, in the configuration in which the both opening / closing pieces are relatively rotated around the vertical rotation axis, the both opening / closing pieces are closed by the urging force of the urging member, and the two opening / closing pieces are closed. It is preferable to store the burner with the burner sideways in the gap.

  By storing the burner integrally with the detachable gotok as described above, the detachable gotok can be quickly attached when the burner is used, which is highly convenient when used outdoors. Further, the mounting portion at the tip of the both open / close pieces in the closed state is rotated around the rotation shaft provided in the both open / close pieces and stored in the center of the open / close pieces. It can comprise so that a mounting part may block | close the opening of the said clearance gap. By comprising in this way, it can prevent that a burner falls out from the said clearance gap.

  In the present invention, the first opening / closing piece and the second opening / closing piece are connected in a freely openable and closable manner to form a detachable adhesive, and both the opening / closing pieces are opened and fixed to the burner. Since both the opening and closing pieces are connected in advance in this manner, rattling between the both opening and closing pieces is unlikely to occur. For this reason, the supporting stability of the cooking utensil placed on the detachable gotok is high, and the cooking operation can be performed safely. And since it can attach to a burner only by opening both the open-close pieces in a closed state, compared with the case where a plurality of separated parts are combined, the attaching / detaching operation of the bar to the burner becomes very simple.

FIG. 9 is a plan view showing a state where the detachable gotok and the burner shown in FIG.

  1 to 4 show a first embodiment of a detachable gotok according to the present invention. The detachable gotok 1 includes a first opening / closing piece 2 and a second opening / closing piece 3 that is elastically connected to the first opening / closing piece 2 so as to form a leaf spring. (See FIG. 1 etc.). The first opening / closing piece 2 and the second opening / closing piece 3 are formed with a placing portion 4 for placing a cooking utensil on the upper end thereof and a receiving portion 5 for receiving and fixing the burner B. When the detachable gotok 1 is attached so as to receive the burner B, the receiving part 5 firmly holds the peripheral surface of the burner B, so that the detachable gotok 1 is securely fixed to the burner B.

  At the end of the receiving portion 5, a retaining portion 6 for preventing the attached burner B from being detached is formed, and the detachable gotok 1 is prevented from being inadvertently detached from the burner B. When a cooking utensil is placed on the detachable gotok 1, the retaining portion 6 strongly contacts the upper end of the burner B with the weight of the cooking utensil. For this reason, the fixed state of the detachable gotok 1 to the burner B becomes more reliable, and the support stability of the cooking utensil increases.

  The two open / close pieces 2 and 3 are opened to each other by a predetermined angle in a state where no external force is applied to them, and a gap is formed between them (see FIG. 1A). If the gap between the two open / close pieces 2 and 3 is closed, it is necessary to widen the gap with the other hand while holding the burner B with one hand. If the gaps are opened only in advance and the gap is secured in advance, the burner B can be attached smoothly and the work efficiency is improved.

  The predetermined angle is set to an angle smaller than the opening angle of both the opening and closing pieces 2 and 3 when the detachable gotok 1 is attached and fixed to the burner B. In this way, when the detachable gotok 1 is attached to the burner B, the detachable gotok 1 is firmly fixed by the urging force that the both open and close pieces 2 and 3 that are elastically connected are intended to close, The stability of the cooking utensil placed on the detachable gotok 1 and the safety during cooking are further improved.

  A locking piece 7 is formed at the lower part of the mounting portion 4 of the second opening / closing piece 3. When the burner B is not used, the detachable gotok 1 is removed from the burner B so that the two open / close pieces 2 and 3 are combined against the urging force of the two open / close pieces 2 and 3 elastically connected. By closing in the direction of the arrow shown in FIG. 2 and locking the locking piece 7 to the lower part of the mounting portion 4 of the first opening / closing piece 2, compact storage can be achieved. For this reason, portability in the outdoors is improved. Moreover, in this locked state, an urging force in the direction of opening both the opening and closing pieces 2 and 3 acts, and the locking action by the locking pieces 7 is further enhanced. For this reason, it is possible to reliably prevent the opening and closing pieces 2 and 3 from being opened carelessly when carrying the detachable gotok 1.

  When the burner B is used, the detachable gotok 1 is attached and fixed to the burner B (see FIGS. 3 and 4). At the time of this attachment, as shown in FIG. 4, the receiving portions 5 formed on the both open / close pieces 2 and 3 of the detachable gotok 1 are brought into contact with each other from the horizontal side of the burner B. Then, due to the abutting force accompanying this abutting, both the open / close pieces 2 and 3 elastically connected open against the urging force (refer to the detachable goto shown by the solid line in the figure). Further, when the detachable gotok 1 is completely attached until it hits the burner B, the open / close pieces 2 and 3 that have been opened once are closed by the biasing force, and the detachable gotok 1 is firmly fixed to the burner B. It becomes a state (refer to the detachable gotok indicated by an imaginary line in the figure).

  5 and 6 show a second embodiment of the detachable gotok 1 according to the present invention. This detachable gotok 1 has the same basic configuration as the detachable gotok 1 according to the first embodiment, but differs in that a locking piece 7 is formed at the open / close end of the second open / close piece 3. Yes. When the burner B is not used, the detachable gotok 1 is removed from the burner B so that the two open / close pieces 2 and 3 are combined against the urging force of the two open / close pieces 2 and 3 elastically connected. By closing in the direction of the arrow shown in FIG. 6 and locking the locking piece 7 to the opening / closing end portion of the first opening / closing piece 2, compact storage can be achieved. The locking piece 7 can also be formed at another position as long as both the opening and closing pieces 2 and 3 can be maintained in a closed state.

  FIG. 7 shows a state where the detachable gotok 1 according to the third embodiment of the present invention is attached to the burner B. FIG. The basic structure of the detachable gotok 1 is the same as that of the detachable gotok 1 according to the first embodiment, but is different in that a leg portion 8 is provided. Since the cylinder (not shown) for supplying fuel to the burner B is used as the leg portion 8 in the detachable trash 1 according to the first and second embodiments, the burner B is used when a small cylinder is used. The self-supporting stability may be insufficient. Therefore, by providing the leg portion 8 on the detachable gotok 1 itself as in this embodiment, the burner B can be stably made independent of the size of the cylinder. For this reason, the further improvement of the safety | security at the time of cooking can be anticipated.

  FIG. 8 shows a state in which the detachable gotok 1 according to the first embodiment of the present invention is attached to a burner B having another shape. The detachable gotok 1 is attached not to the main body of the burner B but to the windshield G provided on the burner B. Since the windshield G does not rise in temperature as much as the main body of the burner B, the temperature rise of the detachable gotok 1 attached to the windshield G is small. For this reason, it is possible to prevent the detachable gotok 1 from being deteriorated due to heating and cooling accompanying the use of the burner B as much as possible.

  In each of the above-described embodiments, the detachable gotok 1 in which the placing portions 4 are provided at intervals of about 120 degrees with respect to the burner B having a circular shape in plan view has been described. Can be attached to the burner B so as to combine the two, and the mounting parts can be configured at intervals of 90 degrees by the two detachable irons 1 and 1. Further, with respect to the burner B having an elliptical shape in plan view, the three mounting portions 4 are not evenly spaced between the adjacent mounting portions 4, for example, “150 ° interval−60 ° interval−150 ° interval”. It is also possible to configure the detachable gotok 1 arranged in the above.

  9 to 12 show a fourth embodiment of the detachable gotok 1 according to the present invention. The detachable gotok 1 is provided with a vertical rotation shaft 9 at the central portion in the length direction of the first opening / closing piece 2 and the second opening / closing piece 3 for relatively rotating the opening / closing pieces 2, 3. A torsion coil spring 10 is provided as an urging member 10 for urging both the opening and closing pieces 2 and 3 in the closing direction so as to be interposed between the opening and closing pieces 2 and 3. The “longitudinal central portion” here is not limited to the exact center, but is allowed in the vicinity thereof. In general, the intake pipe of the burner B is disposed at the center in the length direction, and the vertical rotation shaft 9 must be provided so as to avoid the intake pipe.

  Placed portions 4 are formed at both upper ends of the open / close pieces 2 and 3. The mounting portion 4 is configured to rotate around a horizontal rotation shaft 11 provided in each opening / closing piece 2, 3 and to be stored toward the center of each opening / closing piece 2, 3. . When the opening and closing pieces 2 and 3 are opened against the urging force of the torsion coil spring 10 and the mounting portion 4 is opened, the opening and closing pieces 2 and 3 are cross-shaped crossing at right angles (FIG. 9). (See (c)). At this time, as shown in FIG. 10, the detachable gotok 1 is securely fixed to the burner B by the receiving portion 5 firmly holding the peripheral surface of the burner B. At the end of the receiving portion 5, a retaining portion 6 for preventing the attached burner B from being detached is formed, and the detachable gotok 1 is prevented from being inadvertently detached from the burner B.

  When the burner B is not used, the detachable gotok 1 is removed from the burner B, and the opening and closing pieces 2 and 3 are rotated by the urging force of the torsion coil spring 10 to form an X shape as shown in FIG. The mounting portions 4 at both ends of the open / close pieces 2 and 3 can be closed and stored so as to rotate around the rotation shaft 11 and be folded into a compact state.

  At the time of this storage, as shown in FIG. 12, the burner B can be stored sideways in the gap formed by the two open / close pieces 2 and 3 closed. By storing the detachable gotok 1 and the burner B integrally in this way, the detachable gotok 1 can be quickly attached when the burner B is used, which is highly convenient when used outdoors. At this time, as shown in the figure, by rotating the mounting portion 4 toward the center of both the opening and closing pieces 2 and 3, it is possible to prevent the burner B from falling out of the gap.

  As shown in each of the above embodiments, by making the sticker detachable with respect to the burner B, it can be appropriately replaced with a detachable sticker 1 having a size or shape suitable for the size of the cooking utensil. For this reason, there is a merit that versatility is enhanced as compared with a product in which the burner B and the gotok are integrally configured so as not to be detachable.

  In addition, because Gotok is often exposed to flames, it tends to deteriorate such as deformation with the passage of time of use, but by making Gotok detachable as in the present invention, only the Gotok portion where deterioration is likely to proceed It can be replaced with a new one as appropriate. For this reason, there is also an advantage that the total product life can be extended as compared with a product in which the burner B and the gotok are integrally configured so as not to be detachable.

  In order to further reduce the size, the front end side of the mounting portion 4 can be folded in each of the above embodiments, and in addition to that, in the third embodiment, the front end of the leg portion 8 can also be folded. it can. In this way, portability in the outdoors is further improved.

  In addition, the stability of the placed cooking utensils can be ensured and the number of open / close pieces to be provided can be further increased if it can be stored compactly. For example, three open / close pieces are connected in a Z-shape. It is also possible to adopt a configuration in which four open / close pieces are connected in an M shape.

  Each of the above embodiments is merely an example, and it goes without saying that the invention can be appropriately changed without being limited thereto as long as the problems of the present invention can be solved.
