Description

  The present invention relates to a battery type portable projector capable of emitting a large amount of light.

  In the actual situation in places where there is no small, high-light quantity lighting means that can move freely, such as at night fire scenes and traffic accident scenes, on-site verification is performed using flashlights or large floodlights.

  However, there are problems caused by the brightness of the light such as it is difficult to see minute parts due to insufficient light intensity with flashlights, and it is difficult to find evidence. There is a problem that it is difficult to make lighting that is convenient for verification of places, shadows and backsides.

  A projector that uses a rechargeable sulfuric acid battery can be considered to enable illumination with a large amount of light with a projector that anyone can easily and easily carry, such as a flashlight. Increasing the capacity not only increases the size and weight of the battery itself, but also uses multiple batteries, so the floodlight itself also increases, and the copper iron ballast increases in weight as a ballast in the power circuit for the discharge lamp. Therefore, it is unsuitable for a portable type because the weight increases also in this aspect.

  Therefore, in the present invention, a projector that can illuminate with a large amount of light is made small and lightweight, specifically, a portable projector that can be carried by being put on the shoulder of a person and designed to be easy to use at the site. Let that be the issue.

  The structure of the projector of the present invention made for the purpose of solving the above-mentioned problems is a container with a lid having a substantially eyebrows shape or a gourd shape when viewed from above, and a plurality of rechargeable types in a container having at least a shoulder belt. A battery is removably accommodated and a power circuit connected between the battery and the light source is installed, and a light post having a discharge lamp as a light source is provided with a post member serving as a grip, and the post member is placed in the container The discharge lamp and the power supply circuit are connected by a cord.

  Further, in the projector of the present invention, in the above-described configuration, the power source circuit is reduced in weight by using a special inverter in which a copper iron ballast is omitted. It is downsized. In addition, it is desirable to provide a handle as a hand on a battery container that is a projector main body that houses a battery. In addition, using a curled cord for the connection cord between the discharge lamp and the power supply circuit is convenient for illuminating the object (ground) by removing the light emitter with the discharge lamp from the container containing the battery. There is no entanglement of code.

The portable projector of the present invention has a substantially eyebrows shape as viewed from the top of the container provided with a shoulder belt. So it can be held stably.
Further, since the light projecting body becomes a grip to be gripped with the hand when the post member is removed from the container, the light projecting body gripped with the hand can be freely directed to a place where it is desired to project light.

  Next, an embodiment of the portable projector of the present invention will be described with reference to the drawings. FIG. 1 is a side view of the projector of the present invention with the light projecting body removed from the main body container, FIG. 2 is a plan view of the light projecting body mounted on the main body container, and FIG. 3 is a rear view of the main body container.

  1-3, 1 is a main body container of the projector of the present invention having a substantially eyebrow shape (see FIG. 2) when viewed from above, and a lid body that can be attached to and detached from the container main body 1a located on the lower half of the main body container. It is formed with 1b. Although not shown, the container body 1a of the main body container 1 and the covered lid body 1b are provided with a binding means by an appropriate method such as a clamp type that prevents separation from each other during use. 1A and 1B are curved concave portions formed on the side surface of the main body container 1 as viewed from the above-mentioned plane, and are shaped to fit well to the waist side surface when suspended from the shoulder.

  The main body container 1 accommodates a plurality of rechargeable batteries (not shown) therein, each battery being connected in series (or parallel / series, etc.), and a high-frequency wave not shown but omitting a copper-iron ballast. It is connected to a power circuit including an inverter. A power supply circuit (not shown) has an output terminal connected to a discharge lamp provided on a light projecting body, which will be described later, via a lighting switch 1c, and an input terminal connected to a battery. Can be connected to.

  A handle 2 serving as a handle is provided on the outside of the main body container 1 and on the upper surface of the lid 1b in the illustrated example, and a belt mechanism for locking both ends of a shoulder belt (not shown) before and after the handle 2. Stops 3a and 3b are provided. Further, on the upper surface of the lid 1b, a short support 6 is erected to insert and support a post / grip 5 of a light projecting body 4 to be described later. A lighting switch 1c, a charging plug jack 1d, and a pilot lamp 1e are disposed on the front or rear surface of the main body container 1. FIG. 3 is an example of the rear surface of the main body container 1.

Here, as a light source, the projector 4 has a 70 W metal halide lamp (not shown in the figure) positioned in front of the reflecting surface formed inside the cylindrical or trumpet-shaped main body and attached to the socket. The input end of the lamp is connected to the power supply circuit by a curled cord 7.
Since this light projecting body 4 is formed by a pipe body with a grip 5 provided to hang down from the lower part of the main body, the pipe body is inserted into a short column 6 provided on the lid 1b of the main body container 1, 2, as illustrated in FIG. 3, it is mounted on a main body container 1 containing a battery or the like and integrated as a projector. In the present invention, the light projecting member 4 may be integrated with the main body container 1 by inserting the grip 5 into a hole (not shown) formed in the main body container 1.

  The projector according to the present invention formed as described above has a main body container 1 having a size of about 200 mm, a front width of about 200 mm, and a side width of about 300 mm, for example. It is about 10 kg, and the battery used is a 24 VDC, 9 AH silicon battery.

  In the projector of the present invention, a shoulder belt (not shown) is connected to the belt locking portions 3a and 3b, and when the belt is put on the shoulder, the concave portion 1A or 1B of the main body container 1 just fits the user's waist side. Therefore, the user turns on the switch 1c, pulls out the grip 5 of the light projecting body 4 from the column 6, holds the light projecting body 4 in one hand, and holds the handle 2 with the other hand. The light projecting body 4 is directed to the part to be verified or the object to be verified, and the illumination light is irradiated there.

  Since the light projecting body 4 holding the grip 5 by hand is connected to the main body container 1 via the curl cord 7, even if the main body container 1 is in the waist position, it can be freely directed in any direction. Moreover, since the user who suspended the main body container 1 from the shoulder can walk freely in the state which hold | maintained the said container 1 stably, it is arbitrary regardless of the to-be-verified body (thing). Can be illuminated. Further, since the curl cord 7 is not entangled, there is no problem even if the light projecting body 4 is used by repeatedly attaching and detaching the light projecting body 4 and the main body container 1.

The portable projector of the present invention is as described above, and not only can a large amount of illumination light be radiated freely in any direction, but the weight of the projector as a whole has been reduced by reducing the weight of the power circuit and battery. So, you can hang the main body container from the shoulder with a belt, or carry the handle with your hand in hand. It is extremely useful as a portable large-intensity light source.
In addition, the projector of the present invention is extremely useful as a handy-type large-intensity light source in the event of a power failure due to natural disasters such as an earthquake.
