どがあり、コーナ部の割れが問題となつていた。 In the conventional illumination globe shown in FIGS. 1 and 2, each corner 2 of the square rising portion 1 on the upper circumference was approximately 90 degrees (R is approximately 2 mm), so the diagonal corner portions 2a, When compressive forces F, F are applied to 2c from the diagonal direction, another diagonal corner portion 2b, 2
There was a drawback that d was deformed at an acute angle and cracked. Force F,
Examples of cases in which F is applied include dropping impact in a packaged state, cargo handling impact, and cases where lighting gloves are removed from packaging or attached to lighting equipment, and cracks at the corners have become a problem.

強部を形成したことを特徴とするものである。 The lighting globe of this invention has a rectangular shape with a retaining brim projecting outward on the outer periphery of the opening edge, a rising part on the outer periphery of the brim, and a corner of the rising part. The invention is characterized in that a reinforcing portion is formed on the portion thereof, the reinforcing portion being inclined with respect to a pair of rising portions sandwiching the corner portion.

A holding collar 13 that is rectangular and projects outward on the outer periphery of the opening edge 12 is formed, and a rising portion 1 is formed on the outer periphery of the collar 13. A reinforcing portion 3 is formed that is inclined with respect to a pair of rising portions 1 sandwiching a corner portion. Reinforcement part 3, 3a, 3
b, 3c, and 3d are inclined at an equal angle (135 degrees) to each of the two sides sandwiching them, and their width L
is usually about 15mm.

になる。 Even if forces F and F are applied to the diagonal reinforcing parts 3a and 3c, these reinforcing parts 3a and 3c themselves have a large effect of resisting the forces F and F, and the remaining diagonal reinforcing parts 3b and
Even if the force is transmitted to 3d, there is a large resistance against it. Therefore, there is no need to worry about the corners breaking. The strength of each reinforcing portion 3 can be expected to be approximately three times or more that of the conventional example. Moreover, the moldability of the lighting globe is also improved.

この考案は正方形、長方形の照明用グローブに

いという効果がある。 According to the lighting glove of this invention, since the reinforcing portions are formed at the corner portions of the rising portion of the brim, the corner portions are sufficiently reinforced and cracking at the corner portions can be prevented. Moreover, compared to the case where the reinforcing portion is formed in the entire corner portion of a rectangular lighting globe, there is an effect that there are no restrictions on the shape of the lighting globe that appears in the external appearance.
