Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an improvement in the structure of a small portable heater such as a heat radiation type heater that rotates and folds. This heater is convenient for storing and storing the heater compactly.

(Prior Art) The conventional structure of the above-mentioned heater will be explained based on FIG. 7.

When this type of heater is used, the legs 03 are fixed to the bottom of the main body 01 in contact with the base 02.
The holding member 05 is fixed with a resilient hook portion 051 protruding from an opening 022 at the bottom of the base 02, and when a finger is inserted from below the leg 03 and the hook portion 051 is pushed back. Release the restraint state (indicated by arrow a in FIG. 7), and at the same time rotate the legs 03 while lifting the main body 01
It was necessary to move the hook part 051 away from the restraining position by rotating the main body 01 relative to the leg 03 in the direction shown by the arrow c in the figure.

Therefore, it is necessary to insert one finger into the opening 022 of the leg 03, press down the leg 03, and push up the top of the main body 01 with the other finger, and hold the fingers of both hands almost at the upper and lower ends of the main body 01. Because I have to go, I am forced into a painful posture, and there are no hooks.
It was difficult to confirm whether the restraint of the leg 51 had been released, and there was a fear that the leg 03 would suddenly be unconstrained and begin to rotate. At this time, it was difficult to fix the main body 01 at the current position, and the main body 01 rotated around the grip 08, making it difficult to press the hook portion 051.

(Problems to be solved by the present invention) As mentioned above, the drawbacks such as bad posture when releasing the restrained state of the hook part 051 and the inability to perform the pressing operation sufficiently due to the rotation of the main body 01 are eliminated, and the problem is not painful. In the pressing operation of the hook 051 in the posture, the main body 01
Hook part 05 while securely fixing it in the current position.
The purpose of this is to facilitate the release of the restrained state (1) and facilitate the folding of the legs.

(Means for Solving the Problems) The configuration of the present invention will be described below using FIGS. 1 to 6, which illustrate embodiments.

In use, a base 2 is attached and fixed to the lower part of the main body 1, and the opening box-shaped legs 3 are attached to the front bottom of the base 2 attached to the lower part of the main body 1. The leg 3 is pivotally supported by a pivot pin 4 inserted through the body 2, and the leg 3 is rotatably attached to the main body 2 using the pin 4 as a fulcrum. A retaining member 5 is rotatably supported on the base 2 and has a hook portion 51 at the tip thereof, and is attached to the base 2 while maintaining a rotational elastic force. protruding from the opening 22 of the
The engagement provided at the edge of the opening 32 of the bottom plate 31 when the legs 3 are positioned at an angle in use that is substantially orthogonal to the main body 1, that is, at the position where the bottom plate 31 of the legs 3 touches the lower end of the base 2. 311 is hooked by the hook portion 51 of the holding member 5 and is attached in such a manner that it is restrained by receiving a rotational elastic force. A release member 6 is rotatably supported on the base 2 to rotate and retreat the retaining member 5 against the rotational elastic force of the retaining member 5.
A locking part 61 that engages with the holding member 5 is provided at the base end, and an operating part 62 is provided at the distal end, so that the operating part 62 can protrude from the lower surface of the base 2. It is provided. Use in which the bottom plate 31 of the leg 3 is in contact with the lower end of the base 2 and the hook portion 51 of the retaining member 5 is engaged with the engaging portion 311, and the leg 3 is substantially orthogonal to the main body 1. When the legs 3 are in contact with the front surface of the main body 1 and are almost parallel to the front surface of the main body 1, the main body 1 is in the state of use.
This invention relates to a foldable heater whose legs 3 can be rotated to a stored state in which the front surface of the heater is covered.

(Function) When the operating part 62 is pressed, the holding member 5 is rotated against the elastic force, and the hooking part 51 is released from the hooking state, and when the main body 1 is slightly lifted, the catching part 5 is released.
1 escapes from the restraint position by the engaging portion 311 of the leg 3, the main body 1 is further lifted to make the leg 3 vertically aligned with the main body 1, and then the leg 3 is rotated toward the front side of the main body 1 to release the main body. 1, the front surface of the main body 1 can be hidden, and in this state the heater can have the smallest bulk.

(Example) The present embodiment will be described below based on the drawings.

1 is a main body of a gas heater equipped with a gas burner 7. A box-shaped base 2 made of sheet metal is attached and fixed to the lower end of the main body 1, and a side plate 24 of the box-shaped base 2 made of sheet metal is attached to the lower front side By attaching a pivot pin 4 to the holder, and inserting the pin 4 into a through hole 33 drilled near the front bottom of a thin box-shaped leg 3 made of sheet metal that opens with the pin 4 as a fulcrum, The legs 3 are pivotably attached to the main body 1 so as to be rotatable within a range to be described later. The side plate 24 of the base 2 is inclined so that the height of the base 2 decreases toward the rear, and forms a stepped portion that is smaller in height on the rear side than on the front side at an approximately intermediate position in the front-back direction. A lower plate 21 is provided on the rear side with an opening 22. Then, with the bottom plate 31 of the leg 3 in contact with the bottom plate 21 on the rear side, the main body 1 is maintained in a slightly backward (tilted) state with respect to the vertical direction, and the heater is in the usage position (first
), and when the leg 3 rotates slightly more than approximately 270 degrees, the bottom plate 31 of the leg 3 comes into contact with the front surface of the main body 1 and becomes almost parallel to the main body 1, thereby hiding the guard rod 11, etc. In this state, the heater is stored.

A mounting plate 9 is fixed to the side plate 24 of the base 2, a pin 7 is attached to the mounting plate 9 almost parallel to the pin 4,
A retaining member 5 is rotatably supported, and the retaining member 5 has two coiled rods 50 arranged in parallel and connected in a U-shape at one end. .

Note that the tip of the tendril rod 50 is attached to the top plate 23 of the base 2.
A coiled rod 50, which is a holding member 5, can come into contact with the inner surface of the
is pivotally installed so that a rotational projectile force is generated in the time direction. Reference numeral 51 denotes a hooking claw that is substantially orthogonal to the tendril rod 50 and is formed near the distal end of the one side, and is bent into a substantially V-shape continuously from the proximal end in the rearward direction. On the other hand, a notch 32 serving as an opening is formed in the bottom plate 31 of the leg 3 at approximately the center of the base end, and the tendril rods 50, 50 are caught and engaged by facing the notch 32 at the front end of the bottom plate 31. Engagement piece 3 of a certain width that stops
11 is integrally formed in a protruding manner. Then, the engaging piece 311 is attached to the bottom plate 31 by the hooking claw 51.
is caught and restrained while being pressed against the lower plate 21.

Reference numeral 6 denotes a release member for releasing the rotational restraint force, which is rotatably supported and inserted into the pin 7;
The release member 6 is composed of two spiral rods 60, 60 arranged in parallel as described above, bent into a substantially L shape near the pivot portion, and extended outward at a substantially right angle at one end. It has a locking piece 61, and the locking piece 6
1 to the lower side of the winding rod 50 and hook the hook 5.
1 and 51 to be pushed back, an operating section 62 in the form of integrally coupled tendrils 60 and 60 is formed at the tip of the other side, and the operating section 62 is drilled into the back plate of the base 2. It is installed so as to protrude into the through hole 25,
Further, the operating portion 62 is exposed rearward from the surface of the base 2 and extends slightly upwardly and inclinedly.
The numeral 53 also serves to reinforce the tips of the tendrils 50, 50, and is integrally formed with the hook 51 in a substantially V-shape that is upside down, so that it can be engaged when the legs 3 rotate when opening and closing. This is a guide part for guiding the piece 311 smoothly.

When the release member 6 is pressed with a finger in the direction of the arrow b in the state of use shown in FIG. The main body is rotated counterclockwise against the resistance, and the hook 51 is separated from the engagement piece 311 formed on the bottom plate 31 at the required rotation angle (see the state indicated by the chain line in FIG. 3). Press the back part of body 1 with your hand in the direction shown by arrow c to tilt it slightly forward, and at that position, hold grip 8 and lift body 1, and the legs 3 will gradually rotate in the vertical direction. After that, hold the leg 3 with your fingers and move it further in the same direction for approximately 180 degrees.
When rotated, the legs 3 come into contact with the front surface of the main body 1 to hide the guard rod 11, reducing its total volume and eliminating the risk of the guard rod 11 being deformed or damaged.

Although the above-mentioned release member 6 is bent into an L shape, it may be attached by pivoting an almost straight member, or the holding member 5 and the release member 6 may be made of sheet metal. It's okay. Furthermore, the engaging portion (piece) 311 may be created by fixing a separate member to the bottom plate 31 by spot welding or the like. Furthermore, although the present embodiment shows the case where the base 2 is fixed to the main body 1, it is also possible to form the main body 1 and the base 2 integrally.

(Effect of the invention) To fold and rotate the legs of the heater, press the operating part of the release member, and with the hook part of the restraint member released, press and rotate the main body slightly forward to release the legs. All you have to do is to release the legs from the restraining position from the main body and lift the rear main body. This eliminates the difficult work of pressing the release member while the main body is lifted, as in the past, and eliminates the restraint of the legs from the main body. At the time of release, the positions of the fingers of both hands are near the lower part of the back, and the position of the fingers of both hands is close to each other, so that the operating posture does not deteriorate, which has the effect of making the folding operation very easy.
