Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a portable electric lamp whose light bulb is lit by an internal dry battery or a rechargeable battery.

(b) Conventional technology The applicant of the present application disclosed a battery,
We have proposed a portable electric light in which an inner frame equipped with a light bulb, a permanent contact and a switch contact that connect the battery and the light bulb is housed in an outer frame so that it can be inserted and removed. With this configuration, the pins and permanent contacts that support the bulb get in the way, making it impossible to pick up the bulb with one's fingers. Therefore,
When removing a light bulb, the inner frame is turned upside down and the light bulb is removed from the inner frame by dropping it under its own weight. However, there were cases where the light bulb got caught between the pin and the reflector, and the light bulb could not be dropped.

(c) Problems that the invention aims to solve This invention was created in view of the above problems.
A technical problem is to provide a portable electric light whose light bulb can be easily replaced.

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has an outer frame, an inner frame housed in the outer frame, and an inner frame that is removably attached to the inner frame and inside the inner frame. a light bulb mounted so as to be movable in one direction; and a reflector mounted in front of the inner frame to face the light bulb through a hole in the center, the light bulb moved inward of the inner frame to be taken out. It is characterized in that a push-up piece for pushing up is formed integrally with the inner frame.

(E) Effect Since the present invention is constructed as described above, when removing a light bulb, pull out the inner frame from the outer frame, operate the push-up piece to push the light bulb in the removal direction, and pick the light bulb with your fingers. Remove.

(f) Example An example of the present invention will be described in detail below based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a bottomed cylindrical outer frame (omitted in FIG. 1) made of synthetic resin, the front opening of which is approximately rectangular.
Further, circular engagement holes 2 are bored in both side walls. Reference numeral 3 denotes an inner frame made of synthetic resin that integrally forms a front rectangular frame piece 3a and a power supply housing part 3b extending rearward from the front rectangular frame piece part 3a, and the housing part 3b is housed in the outer frame 1 from the front opening of the outer frame 1. , storage section 3b and frame piece section 3a
The boundary portion 3c between the two is fitted into the rectangular opening of the outer frame 1. Stepped portion 3' at the boundary between the boundary portion 3c and the frame piece portion 3a
comes into contact with the open end surface of the outer frame 1 and prevents the inner frame 3 from being inserted further into the outer frame 1. 4
are a pair of elastic pieces formed integrally with the inner frame 3 from both sides of the boundary 3c of the inner frame 3 toward the storage portion 3b, and the locking protrusion 4' at the tip prevents the inner frame 3 from entering the outer frame 1. When stored, it engages with an engagement hole 2 provided in the outer frame 1 to prevent the inner frame 3 from coming off. Reference numeral 5 denotes a square hole provided on both side walls of the boundary portion 3c of the inner frame 3, into which a claw piece 15 of a reflecting mirror 14, which will be described later, is engaged.

As shown in FIGS. 3 and 4, which are cross sections taken along line A-A and line B-B in FIG. The light bulb 7 connects its glass part to the front rectangular frame piece 3
It is detachably supported by a pin 8 integrally formed with the inner frame 3 so as to protrude into the inner frame 3. Disposed between the battery 6 and the light bulb 7 are a permanent contact 9 that is in constant electrical contact with the battery 6 and the light bulb 7, and a switch terminal 10 that electrically turns on and off. The permanent contact 9 is rotatably supported by a boss 11 that stands integrally from the inner frame 3, and the switch terminal 10 is supported by the outer frame 1.
The light bulb 7 is connected to and separated from the light bulb 7 by a switch knob 12 attached to the front of the upper surface so as to be slidable in the front-rear direction. Reference numeral 13 denotes a push-up piece formed by forming a substantially U-shaped notch in the inner frame 3 to give it elasticity, and when the battery 6 is removed, the permanent contact 9 is placed around the boss 11 in FIG. The light bulb 7 is rotated to the broken line position, and the light bulb 7 is pushed up with a finger while the light bulb 7 is slid to the broken line position regulated by the permanent contact 9, thereby pushing up the light bulb 7.

Reference numeral 14 denotes a synthetic resin reflector having a front edge that is loosely inserted into the rectangular frame piece 3a of the inner frame 3. A hole 14a into which the glass portion of the light bulb 7 is inserted is formed in the center, and a hole 14a is formed at the periphery of the hole 14a. By bringing the flange portion of the light bulb 7 into contact with the light bulb 7, further entry of the light bulb 7 is prevented. Reference numeral 15 denotes a pair of claw pieces that are integrally formed on the left and right side walls of the reflecting mirror 14 facing rearward, and have some elasticity. The reflector 14 is detachably attached to the square hole 5 through the inner frame 3, and the reflector 14 is attached to the inner frame 3. Reference numeral 16 denotes a pair of supporting legs integrally formed on both upper and lower side walls of the reflecting mirror 14 so as to face rearward.

Reference numeral 17 denotes a light-transmitting synthetic resin lens that covers the front opening of the reflecting mirror 14, and its outer dimensions are formed to be approximately the same as the inner diameter of the rectangular frame piece 3a of the inner frame 3, so that when it is attached to the inner frame 3, the lens 17 There is no gap between the outer edge of the inner frame 3 and the inner frame 3. Reference numeral 18 denotes a rib piece formed integrally with the lens 17 from the upper and lower ends of the lens 17 toward the rear, and the claw 18a at the tip is removably engaged with the tip of the support leg 16 of the reflector 14 to attach the lens 17 to the reflector 14. Attach to.

Therefore, when removing the light bulb 7, first remove the elastic piece 4.
is elastically deformed inward of the outer frame 1 with fingers, the engagement hole 2 of the outer frame 1 and the elastic piece 4 are disengaged, and the inner frame 3 is pulled out from the outer frame 1. Next, remove the battery 6 from the power supply storage part 3b of the inner frame 3, tilt the inner frame 3 so that the rectangular frame piece 3a is on top, and connect the permanent contact 9 with its own weight or with one finger as shown in FIG. It is rotated to the position shown by the broken line, and the light bulb 7 is slid (retracted) to the position shown by the broken line in FIG.
Then, push up the push-up piece 13 with your fingers to push up the light bulb 7 as shown by the broken line in FIG. 3, and in this state, remove the light bulb 7 by pinching it with two fingers. At this time, the light bulb 7 is in a state where the glass part is facing into the hole 14a of the reflecting mirror 14, or the fourth
When it is slid (retracted) to the position shown by the broken line in the figure, the rectangular frame piece 3a of the inner frame 3, the elastic piece 4, the pin 8, the permanent contact 9, etc. get in the way, making it impossible to pick it up with two fingers. However, since the push-up piece 13 can push it up above the pin 8 and the permanent contact 9, it can be easily picked up with fingers and removed. Further, even when dropping the light bulb 7 with the inner frame 3 facing backwards, the light bulb 7 can be dropped without getting caught between the pin 8 and the reflecting mirror 14.

(g) Effects of the invention According to the invention, it is possible to simplify the work of removing the light bulb with a simple structure of just providing a push-up piece on the inner frame, and it is possible to provide a portable electric light that is extremely useful in practice. can.
