Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a protective guard device for a hot air heater to prevent accidents such as burns caused by heat from a hot air outlet.

Utility Model No. 54-26866 as a conventional protective guard device
Publication No. 156469, Publication No. 156469, Publication No. 156469
Publication No. 63930 etc. exist.

This conventional configuration will be explained based on Japanese Utility Model Application Publication No. 56-63930. As shown in Fig. 4, a pair of left and right L-shaped supports A, B are guarded by a plurality of connectors B, B, etc. The protective guard device thus assembled is assembled by connecting the body C. Fixing fittings D and D provided at the rear ends of the pillars A and B are fixed to the back of the hot air heater body with screws, and the guard body is assembled. C is configured to cover the front part of the hot air outlet.

However, since this conventional protective guard device supports the guard body C by supports A and A, it requires strong supports, which makes the entire guard device heavy and makes it difficult to move the heater. It's inconvenient.
In addition, a large number of connectors B, B, etc. are required to connect the guard body C and the pillars A, B, etc., which increases the number of parts and requires time and effort to assemble them.

In order to solve the above-mentioned drawbacks, it is known from Japanese Utility Model Application No. 56-29719 that a protective guard is attached directly to the mouth edge of the hot air outlet. By the way, in this conventional configuration, an engagement hole is provided at the edge of the hot air outlet, and an engagement portion formed on the protective guard is detachably engaged with the engagement hole by utilizing the elasticity of the wire material. As a result, since the protective guard is attached to the hot air outlet, it is extremely easy to attach the protective guard, but on the other hand, the protective guard often comes off easily due to mischief by children. In addition, since the structure is such that a protective guard that is approximately the same size as the hot air outlet is attached to the edge of the hot air outlet, the upper and lower parts of the protective guard are close to the hot air outlet, and the upper and lower parts of the protective guard are close to the hot air outlet. If you inadvertently insert your finger into the protective guard, you may come into contact with the edge of the hot air outlet and get burned.
It was insufficient as a safety device.

The present invention has been improved in view of the various problems of the conventional device mentioned above, and includes side rods with the center portions protruding outward on the sides of the upper and lower rods, and a hot air outlet for each of the upper and lower rods. A frame member spaced apart and brought into contact with the front part of the heater, a guard rod formed in approximately the same shape as the side rod, located in a space surrounded by the frame member and attached to the frame member, and a base. The structure consists of a fixed arm whose end is rotatably attached to the side rod and whose tip is fixed to the back of the heater to elastically bring the frame member into contact with the front of the heater, preventing rattling. The purpose of the present invention is to provide a protective guard device that can be installed extremely stably and reliably without causing damage, and can further improve safety.

The guard device of the present invention is shown in Figures 1 to 3 below.
This will be explained based on the diagram. In the figure, reference numeral 1 denotes a frame member formed by bending a single wire to form side bars 1c, 1c with substantially central portions protruding outward on both sides of upper and lower bars 1a, 1b that are parallel to each other. The frame member 1 is formed to have a substantially square shape in plan view and a substantially C shape in side view, and as shown in FIG. It is brought into contact with the front panel of the hot air heater A with a distance of a certain distance, and its lower rod 1b is brought into contact with the lower end of the front panel and the upper surface of the stand with a predetermined distance from the hot air outlet 4 downward. . Reference numerals 2, 2, . . . indicate a number of guard rods formed by bending wire rods into a substantially C-shape to have substantially the same shape as the side rods 1c of the frame member 1. These guard rods 2, 2, . It is located in an enclosed space, and its upper and lower ends are attached to the upper and lower rods 1a and 1b of the frame member 1 by brazing or the like. 3,
Reference numeral 3 denotes a pair of left and right fixed arms formed by bending wire rods into a square shape, and the fixed arms 3, 3 are rotatably attached to both side rods 1c, 1c of the frame member 1 at their base ends. An L-shaped fixing part 3b is formed at the tip and comes into contact with the back surface of the warm air heater A.
is formed, and by bringing this fixed portion 3b into contact with the back surface of the hot air heater A, the side rod 1c of the frame member 1 is pulled by the fixed arm 3. Reference numerals 5 and 5 denote mounting fittings for fixing the fixing portion 3b of the fixing arm 3 to the back surface of the warm air heater A using screws 6.

In the above configuration, the frame member 1 is arranged so that the guard rods 2, 2... cover the front of the lower hot air outlet 4 provided at the lower part of the front panel of the hot air heater A, and the frame member 1 is The fixing arm 3 with the end hooking part 3a hooked to the side rod 1c of the frame member 1 is rotated to bring the fixing part 3b into contact with the back of the hot air heater A, and the fixing part 3b is attached to the mounting bracket 5 and Fix using screws 6. At this time, since the frame member 1 is pulled toward the heater A side by the side rods 1c, 1c fixed arms 3, 3, the upper and lower rods 1a, 1b of the frame member 1 elastically come into contact with the front surface of the heater A. come into contact with Therefore, the frame member 1 can be pressed against the front surface of the heater A by the fixed arm 3, and the frame member 1 can be attached extremely stably without wobbling.

Further, each of the upper and lower rods 1a and 1b of the frame member 1 is brought into contact with a low temperature position spaced apart in the vertical direction from the hot air outlet 4, so that the hot air outlet 4 and the front of the low temperature area above and below the hot air outlet 4 are brought into contact with each other. is also covered by the guard rods 2, 2, and even though a protective guard is installed as in the past, there is no need for fingers etc. to get burned by touching the hot parts, making it safer. can be further improved.

Furthermore, since the fixed arm 3 is rotatably attached to the side rod 1c of the frame member 1, the fixed arm 1c does not get in the way during packing, so that it can be packed compactly.

The structure of the protective guard device of the present invention is as described above, and includes side bars in which the lateral center portions of the upper and lower bars protrude outward. a frame member that is in contact with the front surface of the frame member; a guard rod that is formed in approximately the same shape as the side rod and is located in a space surrounded by the frame member and is attached to the frame member; By being attached to the side rod and fixing the tip to the back of the heater,
Since it is comprised of a fixed arm that brings the frame member into elastic contact with the front face of the heater, the frame member can be pressed against the front face of the heater by the fixed arm, and is extremely stable without wobbling. Can be installed securely.

Further, each of the upper and lower rods is brought into contact with a low-temperature position spaced vertically from the hot air outlet, and the front of the hot air outlet and the low temperature area above and below the hot air outlet is also covered by the guard rod. Therefore, even though a protective guard is attached as in the past, there is no need for fingers or the like to get burned by touching a hot part, and safety can be further improved.

Furthermore, since the fixed arm is rotatably attached to the side rod, the fixed arm does not get in the way when packing.
This has advantages such as being able to be packed compactly.
