It is an example figure which shows the background technique. It is an example figure which shows the background technique. The following is an illustration related to the present invention. However, in some drawings, for convenience of explanation, the illustration of the part having the supply part and the part having the cooking part is omitted (or processed transparently). It is an exploded perspective view. It is an assembled perspective view. However, what is shown on the upper side is a state in which the gas container is not attached. 5A to 5C are operation diagrams showing a process of horizontally rotating and moving the supply portion from the extension portion, and FIG. 5D is an exemplary diagram of the operation process seen from a cross section of a certain portion. 6A to 6C are operation diagrams showing a process of vertically rotating and moving the step support portion from the cross section of one end of the supply portion.

Hereinafter, the present invention will be disclosed with reference to the accompanying drawings.
First, looking at the background art related to the gas burner of the present invention together with FIGS. 1 and 2, it can be seen that the supply unit 100, the extension unit 200, and the cooking unit 300 are largely included.

The supply unit 100 includes a storage unit 110, an adjustment unit 120, and a wiring unit 130.

The storage unit 110 has a space portion 14r of an empty space for storing and fixing the gas container 13, and an opening / closing portion 14d that can be opened and closed is configured to allow the gas container 13 to enter and exit. On the other hand, the storage unit 110 itself can be provided as the supply unit 100.

The adjusting unit 120 is configured at the other end 102 of the supply unit and regulates gas ignition and gas supply. When the gas container 13 is stored in the storage unit 110, the gas container 13 can be detached from the adjusting unit 120.

The wiring portion 130 includes a pipe hinge portion a2 that diffracts (refracts, rotates) together along the body hinge portion a1. The body hinge portion a1 acts as a rotation axis when the supply portion 100 and the extension portion 200 are diffracted with each other. Like the pipe hole, the body hinge portion a1 is perforated with a pipe passage hole along its length. A pipe hinge portion a2 formed by inserting and passing one end 131 of the wiring portion 130 into the pipe passage hole can be added. The wiring portion 130 is subsequently connected from the supply portion 100 to the extension portion 200 via the pipe hinge portion a2. When the supply unit 100 and the extension unit 200 rotate and diffract with each other, the wiring unit 130 is diffracted by a method in which the pipe hinge portion a2 is rotated or twisted together accordingly. One end 131 of the wiring unit 130 is connected to the adjustment unit 120 of the supply unit 100 to adjust the gas supply, and the body in the middle of the wiring unit 130 is wired along the length of the extension unit 200 to transmit the gas supply. The other end 132 of the wiring unit 130 is connected to the combustion unit 310 of the cooking unit 300 to finally transmit the gas supply.

More specifically, in the piping hinge portion a2, a gas nozzle a2a is vertically configured under the adjusting portion 120, a connecting pipe a2b is provided, and the gas nozzle a2a of the adjusting portion 120 and one end 131 of the wiring portion 130 are connected pipes a2b. It is connected to the end by a fitting method and is configured to be rotatable while preventing gas leakage.

The body hinge portion a1 is fitted into the body coupling hole a1a so as to have a body coupling hole a1a having a hole vertically below the other end 102 of the supply portion and projecting onto the other end 202 of the extension portion 200, and rotates horizontally. A body rotation shaft a1b that serves as an axis of the body, a bearing a1c that assists and supports the body rotation shaft a1b, and an angle limiting groove a1d that is provided by being recessed on the other end 202 of the extension portion 200 and separated from the body rotation shaft a1b. It can include an angle limiting protrusion a1e which is formed so as to project downward from the adjusting portion 120 of the portion 100 or the bearing a1c and is fitted into the angle limiting groove a1d to limit the left-right rotation angle.

The extension 200 has approximately the same length as the supply 100. When folded, the supply unit 100 is in contact with the cooking unit 300, and when unfolded, the length of the supply unit 100 itself is as far as possible from the cooking unit 300.

The extension portion 200 is arranged below the bottom surface of the supply portion 100. The shape of the extension 200 corresponds to the outer shape of the supply, and is taken so that it is placed in a straight line in parallel and stacked together, in order to enhance the sense of unity and minimize the obstruction. It is preferable to have an integral outer shape that becomes one with the supply unit 100 after being made.
The extension portion 200 can include a concealing portion c that blocks and protects the external exposure of the wiring portion 130.

In the cooking unit 300, one end 301 of the cooking unit is connected to the other end 202 of the extension unit, and a combustion unit 310 in which gas ignition and combustion are performed is configured in the center of the upper end thereof, and the peripheral edge of the combustion unit 310 is configured. Is provided with a support portion 320 composed of a plurality of (four in the example of the drawing) for supporting and supporting the container so as to be horizontally diffractible.

In the folding mode, the support portion 320 of the present invention is bent corresponding to the supply section 100 and comes into close contact with and contacts the body of the supply section 100. That is, since the vertical body d3 of the support portion 320 wraps the outer shape (outer circumference, appearance) of the supply portion 100 and is overlapped and integrated, the support portion 320 is folded toward the supply portion 100 so as to be in close contact with the outside of the supply portion. The overall length and width of the gas burner can be minimized by aligning with, increasing the sense of unity and minimizing the obstacles. On the contrary, in the unfolding mode, the body of the support portion 320 is made to spread radially around the cooking portion 300 so that the container can be supported.

The other end 102 of the supply portion and one end 201 of the extension portion are hinged to each other via the body hinge portion a1. That is, the supply portion 100 and the extension portion 200 are diffractably connected to each other via the body hinge portion a1. If the configuration of the body hinge portion a1 is diffracted and folded or unfolded, the supply portion 100 and the extension portion 200 can be folded so as to overlap each other when the gas burner is not used (during portable storage). That is, one end 101 of the supply portion and the other end 202 of the extension portion can be aligned with each other. Thereby, one end 101 of the supply unit and one end 301 of the cooking unit 300 can be made to meet together. That is, the supply unit 100 and the cooking unit 300 can be brought into close contact with each other or close to each other.

On the contrary, when the gas burner is used, the supply unit 100 and the extension unit 200 can be expanded to each other. That is, one end 101 of the supply portion and the other end 202 of the extension portion can be made far from each other. As a result, the distance between one end 101 of the supply unit and one end 301 of the cooking unit can be made as far as possible. That is, the supply unit 100 and the cooking unit 300 can be separated and expanded at a long distance.

One end 101 of the supply part approaches one end 301 of the cooking part / the other end 202 of the extension part, and the supply part 100 and the extension part 200 are overlapped to minimize the volume, and conversely, the volume is maximized by being far away. As described above, the other end 102 of the supply portion and the one end 201 of the extension portion are hinged to each other diffractively via the body hinge portion a1.

The body hinge portion a1 can be adopted as a normal hinge a'member whose directions (f1) and (f2) are diffracted on a two-dimensional plane like scissors or a hinge.

Next, the present invention will be investigated in detail together with the embodiments shown in FIGS. 3 and below.

Let us examine the gas container connection limiting means of the present invention.

In the present invention, when not in use (when the gas burner is not used), the supply unit 100 {including the storage unit 110} and the cooking unit 300 {including the combustion unit 310 and the support unit 320} are adjacent to each other as much as possible. (Including contacting), the method of overlapping and folding the supply unit 100 and the extension unit 200 {including the concealment unit c} is adopted. At this time, there is a problem that the gas container 13 must be provided in a state of being separated from the adjusting unit 120 so that the gas supply is fundamentally cut off for safety reasons such as gas safety inspection standards. be.

However, in the method in which the angle limiting projection a1e is configured in the supply unit 100 as in the background technique, the angle limiting projection a1e configured in the supply unit 100 rotates and moves together with the supply unit, so that the angle limiting projection a1e is the supply unit. It is not easy to provide the safety standards required by gas safety inspection standards, as the relative movements and influences of the gas container 13 mounted within 100 cannot be achieved.

Therefore, the present invention provides a gas container connection limiting means configuration capable of limiting the gas supply at the same time as having the function of limiting the diffraction (rotation or refraction) angle of the supply portion with respect to the extension portion as in the background art.

First, the other end 102 of the supply portion and one end 201 of the extension portion are hinged to each other via the body hinge portion a1, the body hinge portion a1 includes the body rotation shaft a1b, and the pipe hinge portion a2 passes through the body hinge portion a1. I will clarify.

The gas container connection limiting means of the present invention includes the connection limiting groove a1d0 and the connection limiting protrusion a1e0, and contrary to the background art, the connection limiting groove a1d0 is located at a position separated from the body hinge portion a1 under the other end 102 of the supply portion. Arc-shaped (arch-shaped, eyebrow-patterned) grooves (holes) are formed radially on the bottom surface. More specifically, the radial connection limiting groove a1d0 is formed by punching an eyebrow pattern with a predetermined separated radius with the body hinge portion a1 at the center of the circle.

Correspondingly, the connection limiting projection a1e0 is formed so as to project vertically on the upper surface of one end 201 of the extension portion 200 at a position separated from the body rotation axis a1b. At this time, the separation distance must be scheduled to be the same as the separation distance (that is, the radius) of the connection limiting groove a1d0 from the body rotation axis a1b.

More specifically, referring to the lower left side of FIG. 3, the connection limiting projection a1e0 takes the form of a bolt (or screw), and the head portion a1e0b is located inside the closed space of the extension portion 200, and the head portion a1e0b is located. The body portion a1e0a is installed (fixed) so as to extend (pass) through (pass) the extension portion 200 from the body portion a1e0a to the outside of the upper side. That is, like the connection limiting groove a1d0 formed with the body hinge portion a1 at the center of the circle and having a predetermined separation distance (radius), the connection limiting protrusion a1e0 is provided at the same separation distance from the body hinge portion a1. Be done.

The assembled state of FIG. 3 is shown in FIG. It can be seen that in the assembled state, the body of the connection limiting protrusion a1e0 is located in a state of intervening in the connection limiting groove a1d0 (insertion inserted through the connection limiting groove). In relation to the exact installation position for efficiently providing the functions of the present invention, referring to the lower right side of FIG. 3, the connection limiting projection a1e0 is the extension center line ce (the center in the length direction of the extension portion). It is located on one side of the center line, ce1 (one side of the left or right side of the center line), which is separated from the center line.

As a result, the connection limiting projection a1e0 is additionally located and in contact with the one side (ce1) direction end of the arc-shaped groove of the connection limiting groove a1d0, so that it acts as a locking action, and the supply unit 100 is scheduled. Diffraction is restricted on the opposite side of the diffraction direction. Then, if the supply unit 100 is widened to the maximum angle (roughly right angle) with respect to the extension unit 200, the connection limiting projection a1e0 is the end portion in the other side ce2 direction of the connection limiting groove a1d0 so that further diffraction is restricted. The arc length of the connection limiting groove a1d0 is planned so as to have a locking action. When all diffraction is allowed here and there, or when diffraction is allowed excessively beyond the maximum angle, the pipe hinge portion a2 configured together with the body hinge portion a1 is overloaded and there is a risk of gas leakage. This is to reduce worries and prevent loosening of parts related to diffraction such as the body rotation shaft a1b and the piping hinge portion a2 of the body hinge portion a1 during long-term use.

In particular, in the position where the connection limiting protrusion a1e0 of the present invention is arranged, the more important reason for locating the connection limiting protrusion a1e0 on one side of the center line is related to the safety problem, and the gas burner is folded when the gas burner is not used. In this state, the gas container nozzle of the gas container 13 is in contact with the adjusting unit 120 so as not to be connected.

In the above-described configuration and arrangement as shown in FIGS. 3, 4, and 5, first, the connection limiting projection a1e0 is on one side of the connection limiting groove a1d0 in a state where the supply portions 100 are arranged side by side on the extension portion 200. It is located at the end in the ce1 direction. Therefore, the gas container 13 is locked (closed), and the gas container 13 cannot move (move) to the other end 102 / adjusting unit 120 side of the supply unit any more. For this purpose, the distance is measured and scheduled in advance so that the gas container nozzle of the gas container 13 cannot be connected to the adjusting unit 120.

In FIG. 5B, if the supply unit 100 is diffracted and moved r1 to either the left or right side (clockwise in the drawing), the arcuate groove of the connection limiting groove a1d0 diffracts at a predetermined angle around the body hinge portion a1. At this time, since the connection limiting projection a1e0 fixed to the extension portion 200 is stopped at the fixed position of the extension portion 200 while being interposed in the connection limiting groove a1d0, the connection limiting groove a1d0 is eventually reached. Will slide through the connection limiting protrusion a1e0 and pass by in an arc motion. Relatively (conversely), the connection limiting projection a1e0 passes through the connection limiting groove a1d0 in an arc motion.

Next, let's examine the functional operation method step by step with FIG. 5 (in order to show the bottom surface state inside the supply part, the adjustment part shows only the position and not shown).

In the first folded step of FIG. 5A, the gas container 13 is attached to the supply section 100, and the edge of one end of the gas container 13, that is, the edge 13a of one end of the gas container is in contact with the body of the connection limiting protrusion a1e0, and the gas container is engaged. The gas container nozzles of 13 are separated from the adjusting unit 120 at a distance, and the gas supply is cut off.

In the step of the expanding process of FIG. 5B, when the supply unit 100 is diffracted with respect to the extension unit 200 and an arc motion is performed {diffraction movement r1 is performed}, the connection limiting projection a1e0 is also provided at one end edge 13a of the gas container. A circular motion is made while in contact with (contacting) the body of. At this time, due to the arc locus of the circular motion, the gas container 13 moves backward d1 slightly retreating to the one end 101 side of the supply portion, and the gas container one end edge 13a has a connection limiting projection a1e0 as shown in FIG. 5B-2. Continue to maintain contact with. In addition, the backward d1 movement of the gas container is safe by further separating the gas container 13 from the regulating unit 120 to ensure that the gas supply is cut off and to prevent unexpected accidents that may occur while expanding the supply unit 100. It can enhance the sex.

At the step where the deployment is completed as shown in FIG. 5C, the contact of the gas container one end edge 13a is released from the connection limiting protrusion a1e0, and the gas container can be moved forward. That is, in a state where the supply unit 100 is completely expanded from the extension unit 200, the gas container 13 can be advanced. As a result, the gas container nozzle can be connected to the supply unit 100, and the function of a normal gas burner can be performed.

FIG. 5D is a drawing seen from the cross-sectional direction of the gas container, and together with this, the cutoff (contact) between the gas container one end edge 13a and the connection limiting protrusion a1e0 and the release relationship thereof will be investigated. In each step of FIGS. 5A and 5B, when the diffractive motion r1 of the gas supply unit 100 is performed, the connection limiting projection a1e0 and the gas container one end edge 13a are kept in contact with each other while sliding s1 and s2 as shown in FIG. 5D. That is, the contact maintenance states a1e0-1 and a1e0-2 are maintained. Then, at the time when the diffraction of the gas supply unit 100 is completed, the connection limiting projection a1e0 becomes a state a1e0-3 separated from the edge 13a at one end of the gas container, and the cutoff is released.

The arrangement of the connection limiting protrusion a1e0 is located on one side of the center line ce1 {one side of the left or right side of the extension center line ce} as shown in the right side of the lower end of FIG. 3 so that the function of FIG. 5D is often performed. Scheduled to do. On the contrary, the body hinge portion a1 is slightly detached from the center line other side ce2 {the other side on the left and right of the extension center line ce} because it is arranged separately from the connection limiting protrusion a1e0. The connection limiting groove a1d0 / one end edge 13a of the gas container is provided with a radius of gyration (radius) with respect to the connection limiting projection a1e0.

At this time, as can be confirmed from FIG. 5D, the position state all0-1 of the connection limiting protrusion a1e0 is arranged on the center line one side ce1, and its body (or at least the upper end of the body) is the gas container 13 / one end edge of the gas container. When the supply unit 100 and the extension unit 200 are lined up while maintaining contact with the 13a (before expanding, the gas container 13 is prevented from moving forward toward the adjustment unit 120, and the gas supply is cut off. The arrangement must be planned at such a position, and the body length (height of the upper end of the body) of the connection limiting protrusion a1e0 must also be planned. This is because the cross section of the gas container 13 has a circular shape. To provide a state a1e0-1 and a1e0-2 in contact with or not in contact with the gas container 13, respectively, depending on the body length and the position of the connection limiting protrusion a1e0 as in 5D. Is.

After the supply unit 100 and the extension unit 200 are expanded to the maximum angle, the state a1e0-3 of the connection limiting projection a1e0 is completely separated from the gas container 13 / one end edge 13a of the gas container (contact and cutoff are released). The height and position of the connection limiting protrusion a1e0 must be scheduled together so that the gas container 13 can freely move toward the adjusting portion 120. In the embodiment of the drawing, the connection limiting projection a1e0 is further away from the gas container 13 than the first state a1e0-1 after the supply unit 100 is expanded to the maximum angle for the complete release of the cutoff. It was planned to be 3.

Let's examine the support portion 320 of the present invention.
The support 320 is a plurality of four, arranged radially, each configured to be horizontally folded or unfolded to the bottom surface of the support 320 via a hinged coupling. One end b0 of the support portion that is horizontally rotatably hinged to the bottom surface of the cooking unit 300, the support portion bottom body z1 that extends from the hinge connection point of the support portion b0 to the bottom in a rod shape, and the support portion bottom body. A pair of vertical support portions vertical bodies z2 and z3 and a front / rear support portion formed by extending the front and rear pairs vertically upward from z1 in a rod shape and bending corresponding to the outer peripheral shape of the supply portion 100. A rod-shaped body is formed as a body at each upper end of each of the vertical bodies z2 and z3, and includes a support portion support body z4 which is arranged substantially parallel to the support portion bottom body z1 and is provided so as to support and support the container. It consists of.

Here, the support portion bottom body z1 is arranged so that one end b0 of the support portion and its hinge connection are separated from each other at a position farthest from the combustion portion 310 of the cooking portion 300, and the hot air generated in the combustion portion 310 ( The purpose is to protect it from fire.

In particular, unlike the background technology, the front support vertical body z2 is arranged away from the hot air of the combustion part 310 and does not come into direct contact with (do not come into contact with) the hot air, so that the body becomes excessively hot and the use of the gas burner ends. Problems and accidents such as excessive cooling (cooling) time, deterioration due to weakened rigidity due to high heat, and transfer of the heat to the cooking unit 300 or the gas burner body to heat it. Can be prevented. Further, since the front-rear support portion vertical bodies z2 and z3 are provided in a pair at a distance in parallel, the bearing force that supports the container can be increased without being distorted even if the load is biased.

Let's examine the step support portion g1a of the present invention.
After expanding the supply unit 100 placed on the extension unit 200, a high and low step is generated between the bottom surface of the extension unit 200 and the bottom surface of the supply unit 100 with respect to the support unit bottom body z1. Therefore, one end 101 of the supply unit is in a state of floating in the air, and one end 101 of the supply unit descends (falls) during use (cooking) due to the weight of the gas container 13 and the supply unit 100 itself, an external load, and an impact. There is a danger of tilting. However, when the step support is normally exposed to the outside as in the background technology, it gets in the way of the hand and the case when carrying.

In order to overcome such a problem, a vertically rotating step support portion g1a is provided on the cross section of one end 101 of the supply portion. In the following, reference will be made to FIGS. 3 and 6, but for convenience of explanation, in FIGS. 6A and 6B, the cooking unit 300 is not shown and only the position is shown.

The step support portion g1a of the present invention is provided as a body of a flat plate member having a length, and the step support portion rotation shaft g1a1 rotates at one end 101 of the supply portion so that the upper end of the step support portion body rotates on the cross section of one end 101 of the supply portion. The lower end of the step support portion is hinged to the cross section of the above, and the bottom contact surface g1a2 provided by being bent in an L shape so as to be in good contact with the bottom and support the supply portion 100 is configured.

Examining the operation process, the step support portion g1a is folded in a state of lying parallel to the upper surface of the extension portion 200 in the state of FIG. 6A in which the supply portion 100 is overlapped with the extension portion 200. In the state of FIG. 6B in which the supply unit 100 diffractically moves r1 and begins to separate from the extension unit 200, the operation r5 in which the step support portion g1a rotates vertically around the step support portion rotation axis g1a1 and descends to the bottom is started. .. Such a descending operation r5 is performed by a gravitational action or a user's manual operation. In the state of FIG. 6C in which the supply unit 100 is completely expanded, a wider area of the bottom contact surface g1a2 contacts the bottom and supports the supply unit 100 {particularly, one end 101 of the supply unit} via the step support portion g1a. It is spread out to do. On the other hand, when folding, the operation proceeds in the reverse process to the above, and at this time, if the supply unit 100 is pushed in the opposite direction of the diffraction movement r1 in the illustration of FIG. 6B, the step support portion g1a becomes the side surface of the extension portion 200. It will be automatically folded like the initial state.

In addition to that, in the process as described above, a spring device that can be elastically restored can be added to the step support rotation shaft g1a1 to substitute for gravity action and manual operation, and a known elastic restoration device is cited here. can do.
