Description

Description ATTACHABLE LANTERN

Technical Field

[1] The present invention relates to an attachable lantern, and more particularly, to an attachable lantern having great enhanced convenience in use and solidity and stability in construction. Background Art

[2] Generally, one wears a broad-brimmed cap to protect one's face from sun and to ensure one's visual field by shading the light when fishing, exercising, traveling, or leisure and sports activity such as hiking and jogging. One also wears the cap in night workshop.

[3] The cap can be used in mounting, fishing, traveling done during the day with no problem, but it can be not effectively used during the night because of poor visual field and a lantern is should be required.

[4] One should hold the lantern with one's hand when mounting or traveling, and therefore one's activity is unnatural and an accident may be happened because one should move following a region lighted by the lantern and this lets one's attention be loose.

[5] Further, in night workshop where one's hands are free and light is required, working is not well done since a worker should hold the lantern with one hand and work with the other hand. Also, in case of requiring both hands in working, another worker should help to hold the lantern.

[6] To solve these problems, it is widely known a radiation lamp attached on a band which will be worn at head or a lantern which is attachable on a rim of a cap by clips.

[7] In case of wearing the band attached with radiation lamp, user feels inconvenient in use since the band is closely contacted on one's head and presses one's head.

[8] Meanwhile, in case of using the lantern which is attachable on a rim of a cap by clips etc, user also fees inconvenient in use since the lantern is slant toward front of the rim or easily detached from the rim.

[9] The prior lantern had required disposable batteries as power source and these dis posable batteries should be often replaced. Therefore, convenience in use for users was dropped and lots cost was needed to replace new disposable batteries. Job to weld lid lines of a power source of a lamp on a circuit board was very difficult since the connection relationship between a battery and a circuit board was complicated. Also, production rate was decreased and inferior products were often appeared since it was hard to firmly connect the lid lines of the power source of the lamp onto the circuit board.

[10] To solve this problem, recently, rechargeable batteries which can be easily recharged by input terminal have been applied, but they required great increase in volume and weight of a lantern, which caused users to be still inconvenient.

[11] In case of increasing in weight of a lantern, the lantern was inclined towards front of a rim of a cap by its weight, which caused user to be inconvenient in use. Also, in case of increasing in volume of a lantern, user's sight field was hidden by the lantern, which caused its original usage to be not realized.

[12] Prior lanterns had required disposable batteries which should be disposed, which caused environmental pollution.

[13] Prior lanterns had a case which is not firmly assembled, which caused it was weak in impact, and fitting among its parts was not good, which caused assembling process or manufacturing process rate to be decreased. This also caused producing and assembling rate to be very deteriorated and further to increase manufacturing cost. Disclosure of Invention Technical Problem

[14] The present invention is created to solve the above conventional problems.

[15] One object of the present invention is to provide an attachable lantern enabling to minimize user's inconvenience in use by being easily attached on and detached from an object such as a cap and by being firmly attached on the object.

[16] Another object of the present invention is to provide an attachable lantern enabling to raise safety in night and to be used other usage such as alarm light or a signal light by its light being easily sensed by other people.

[17] Still another object of the present invention is to provide an attachable lantern enabling to give convenience in use and decrease in cost caused by often replacement of prior disposal batteries by applying rechargeable batteries and by using them with necessary recharge, and also enabling to decrease in size and in weight by decreasing volume and weight of prior rechargeable batteries

[18] Still another object of the present invention is to provide an attachable lantern enabling to increase assembling and producing rate and to greatly decrease manufacturing cost by enhancing intensity against outer impact through much firm assembly structure of its case and by enhancing fitting force between each part.

[19] Still another object of the present invention is to provide an attachable lantern enabling to decrease its size and weight by optimizing its inner space.

[20] Still another object of the present invention is to provide an attachable lantern enabling to greatly increase production rate and to minimize inferiority rate by easily and firmly welding lid lines of a lamp onto a circuit board. Technical Solution

[60] Any one of the facing surfaces of the lower plate 13 and the upper surface 21 is provided with one or more arranging guides 51 and 53 to be protruded.

[61] The arranging guides 51 and 53 are composed of one or more first arranging guides

51 for arranging the facing surfaces between the battery 45 and the circuit board 71 and one or more second arranging guides 53 for arranging long sides of the battery 45. On the same line with the second arranging guides 53 one or more connecting recesses 54 are protruded, and the connecting protrusions 52 which are protruded from the upper plate 21 can be inserted and connected into the connecting recesses 54. The connecting protrusions 52 are reinforced by a cross-type reinforcing rib 52a. The connecting recesses 54 and the connecting protrusions 52 can also function to arrange the mounting position of the battery 45 and the circuit board 71.

[62] The lower plate 13 is protrudingly formed with a pair of hook connecting portions 61 toward from the lower plate 13 to the upper plate 21, wherein the hook connecting portions 61 arrange the mounting position of the battery 45 and the circuit board 71 together with the first arranging guides 51 and the second arranging guides 53. Otherwise, the hook connecting portions 61 can protrude between the battery 45 and the circuit board 71. The hook connecting portions 61 are formed with a reinforcing rib 61a to be perpendicular to it, and it is reinforced by the reinforcing rib 61a.

[63] The upper plate 21 is formed with a hooking portion 65 to be protruded toward the lower plate 13, and the hooking portion 65 is connected to the upper plate 21 and the lower plate 13 by engaging with the lower plate 13. The hooking portion 65 is perpendicularly formed with a reinforcing rib 65a, and the reinforcing rib 65a can reinforce the hooking portion 65.

[64] As shown in FIG. 5, the hooking portion 65 has a periphery wall 67 which is protruded toward from the upper plate 21 to the lower plate 13 and a jaw 69 which is engaged with a hooking hole 63 of the hook connecting portions 61 of the lower plate 13. The jaw 69 is formed on the end of the periphery wall 67 so as to outwardingly protrude from the outer periphery surface of the periphery wall 67. The end area of the jaw 69 has a slanted surface which is slanted toward from the end of the periphery wall 67 to the upper plate 21 so as to easily connect the upper plate 21 to the lower plate 13 in hook type.

[65] Thereby, the upper plate 21 can be easily assembled with the lower plate 13 by the slanted surface of the jaw 69 of the hooking portion 65. The hooking portion 65 and the hook connecting portions 61 function to firmly hold the upper plate 21 and the lower plate 13 and further to easily mount the battery 45 onto the mounting portion 47a and 47b.

[66] With this structure, the upper plate 21 and the lower plate 13 are much firmly connected from each other by the hook connecting portions 61 and the hooking portion 65, and by the connecting protrusions 52 and the hooking portion 65. Also, the hook connecting portions 61 and the hooking portion 65 are protruded, but they are reinforced by the reinforcing ribs 61a and 65a, and therefore much firm connection between the upper plate 21 and the lower plate 13 can be achieved.

[67] By this, the case 11 of the present invention can have firm assembling and connecting structure and its intensity against outer impact is increased. Since the battery 45 and the circuit board 71 are fitted without distance in the upper plate 21 and the lower plate 13 by the first arranging guides 51 and the second arranging guides 53 formed on the upper plate 21 and the lower plate 13, fitting between parts is better and inner space is optimized in use.

[68] The facing surface between the upper plate 21 and the lower plate 13 is provided with the mounting portion 47a and 47b on which the battery 45 is mounted, and the mounting portion 47a and 47b are respectively formed with latticed reinforcing ribs 49a and 49b. Owing to the latticed reinforcing ribs 49a and 49b, the upper plate 21 and the lower plate 13 are minimized in thickness and reinforced in intensity, by which the case 11 of the present invention can be small and light in size and weight.

[69] The case 11 houses the circuit board 71 formed with circuits for providing power source to the main lamp 75 and the auxiliary lamp 81. Herein, the circuit board 71 is safely mounted between the upper plate 21 and the lower plate 13, and it is provided with circuit for providing power source to the main lamp 75 and the auxiliary lamp 81. The circuit board 71 covers the battery 45, and it has the input terminal 76 on one side thereof. The input terminal 76 is connected with the input jack 45a, and the rechargeable battery 45 is supplied with outer power source through the input jack 45a. The circuit board 71 has an outer terminal 77 on the other side thereof, and the circuit board 71 is connected with an output jack 45b. The output jack 45b can be used to recharge other electrical products such as a navigator, a mobile phone or MP3 player owing to the output jack 45b. Disposal batteries can be applied as the power source applied to the lantern of the present invention, but on considering troublesome to often replace new disposable battery, increase in cost to replace new disposable battery, and environmental problem raised disposed batteries a rechargeable battery is preferably used.

[70] The rechargeable battery is recharged by an outer power source electrically connected to an input terminal of the lantern through an input jack, and therefore it can be used for long time without replacement.

[71] The circuit board 71 has a first, second and third rims 7 Ia, 7 Ib and 71c which cover the battery 45, and the first rim 71a is formed with an inserting hole 7 Id on the end thereof.

[72] Further, with the structure in which the circuit board 71 covers the battery 45, the circuit board 71 can have much simple circuit pattern, and therefore the lid lines 79 of the main lamp 75 or the auxiliary lamp 81 can be directly welded to the circuit board 71 without other additional cables (or lines) or processes. By this, the present invention has an effect in which welding work can be very easily done. For example, the lid lines 79 of the main lamp 75 is near and directly welded to the first rim 71a of the circuit board 71, and therefore welding structure between the lid lines 79 and the circuit board 71 is improved and production rate can be increased.

[73] The main lamp 75 is electrically connected to the circuit board 71, and it is supported by the lamp bracket 25 disposed on the front portion 15 of the case 11 and radiates its light toward of the case 11. In this embodiment, four main lamps 75 are shown, but the number of the lamp 75 is limited. Therefore, lighting of the main lamp 75 can cause user to easily walk or work.

[74] The auxiliary lamp 81 is disposed on the slanted surface 19a of the case 11, and its lid lines are welded on both sides of the circuit board 71. The auxiliary lamp 81 radiates its light by obtaining power source from the battery 45, and it flickers with constant time interval. With the flickering of the auxiliary lamp 81 on both sides of the case 11, user's position can be easily informed to others under urgent situation or emergent time. Also, others can sense user's position and therefore safety in night can be guaranteed.

[75] Herein, the main lamp 75 and the auxiliary lamp 81 are preferably LED.

[76] The lantern 10 according to the present invention has a first switch 85 electrically connected to the battery 45 and for on/off the power applied to the lamp 75, and the auxiliary lamp 81 and a second switch 91 electrically connected to the first switch 85 and for controlling the operation of the first switch 85.

[77] Herein, the first switch 85 is push button switch, and the second switch 91 is slide switch.

[78] The first switch 85 and the second switch 91 pass through each through-holes 21a and 21b of the upper plate 21 and protrude toward the flat surface of the upper plate 21.

[79] With this structure, when the second switch 91 and the first switch 85 are on, the power of the battery 45 is supplied to the main lamp 75 and the auxiliary lamp 81 at the same time, and the main lamp 75 and the auxiliary lamp 81 also radiate at the same time

[80] Alternatively, when the second switch 91 is on, only the main lamp 75 is on if the first switch 85 in pushed one time, the auxiliary lamp 81 is on if the first switch 85 in pushed one more time, and the main lamp 75 and the auxiliary lamp 81 are all off at the same time if the first switch 85 in pushed two more time.

[81] Further alternatively, on condition in which one of the first switch 85 and the second switch 91 is on, the power of the battery 45 is not supplied to the main lamp 75 and the auxiliary lamp 81, but supplied to the output jack 77. By this, other electric products can be recharged by the output jack 77.

[82] The lantern of the present invention can further comprise an ultrasonic generator 90 to connect to the circuit board 71, and the ultrasonic wave from the generator 90 moves through a speaker hole 91. This can cause any insects such as a mosquito or a fly not to closely come.

[87] On condition that the second switch 91 installed on the upper plate 21 of the case 11 of the lantern 10 firmly attached to the rim 3 is on, the main lamp 75 and the auxiliary lamp 81 radiate their light owing to the power supplied from the battery 45 if the first switch is pushed one time.

[88] At this time, the main lamp 75 is placed the end of the rim 3, and therefore light from the lamp 75 is not interrupted by any structure and no shadow exists. Also, the main lamp 75 is placed before user's eyes, and therefore much wide field of vision can be obtained, which light angle of the main lamp 75 can agree with the visible angle of user. When a user wear the cap 1, the cap 1 is held on the head of the user. When user rotates his/her head, the main lamp 75 also rotates and lights front side, whereby user's vision field easily being obtained in night.

[89] The auxiliary lamp 81 supplied power from the battery 45 is on and off with constant time interval. This causes light to come out from front side of the rim 3 and also both sides of the rim 3, and therefore user's position can be easily informed to others under urgent situation or emergent time.

[90] On condition that the first switch 85 is on, power is not supplied from the battery 45 and the main lamp 75 and the auxiliary lamp 81 are off if the second switch 91 is off, whereby discharge of electricity of the battery 45 can be prevented. A pair of side portions between the front potion and the rear portion has a slanted surface to have an obtuse angle for the front portion, and flickering auxiliary lamp is disposed on the slanted surface. The detachable unit to cover the rim of the cap is provided between the case and the clip. Therefore, user's position can be easily informed to others in night, and therefore safety in night can be guaranteed. The clip is prevented from being damaged and product's age can be extended by decreasing the fatigue load applied to the clip even extreme exercise such as hiking or jogging

[91] The lid lines of the main lamp are welded to the rim of the circuit board near to the battery, and therefore welding work is easy and the lid lines of the main lamp is firmly connected to the circuit. Therefore, production rate can be increased and time required in welding and inferiority of products can be decreased.
