Description

  The present invention relates to a lantern shade for functioning as a lantern that illuminates the surroundings by being attached to a lamp that irradiates in one direction during use.

  For outdoor activities such as mountain climbing and trekking, various equipment is required depending on the course. Lighting equipment is a must-have equipment, especially in the event of nighttime travel. Illumination equipment required here includes a lantern, a headlamp, and an indicator lamp (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3 below).

  By the way, in outdoor activities where various equipment other than lighting equipment is required, weight reduction of equipment is required.

  In addition to reducing the weight of each piece of equipment independently, it is possible to reduce the number of equipment by consolidating the functions of different equipment into one piece of equipment. When considering the functional integration of the equipment in the lighting equipment, the functions of the lighting equipment are roughly classified into two. One is a lamp function that illuminates one direction when moving, and the other is a lantern function that illuminates the surroundings when resting. Since the lamp function needs to illuminate far away in a relatively narrow range, the lighting equipment that performs the lamp function adopts a form suitable for it. On the other hand, since the lantern function needs to illuminate the vicinity in a relatively wide range, the lighting equipment that fulfills the lantern function adopts a form suitable for it.

  Due to the difference between the lamp function and the lantern function as described above, the weight of the lighting equipment that serves both the lamp function and the lantern function is more than the total weight of the lighting equipment that serves both functions. No lighting equipment has been proposed that can be reduced sufficiently. Specifically, although a lamp function that simply added a lantern function to the lamp function has been proposed, the shade that allows the lantern function to be displayed can be stored compactly so as not to interfere while the lamp function is being used. Nothing was proposed. Therefore, the present inventor is configured so that the shade that can perform the lantern function can be stored compactly while performing the lantern function while using the lighting equipment that performs the lamp function, when the lamp function is performed. Therefore, we will make a proposal that can solve such problems.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a lantern shade that can also perform a lantern function by being mounted on a lighting device that performs a lamp function. It is possible to provide a lantern shade that can be stored compactly while being able to perform the lamp function.

  In order to solve the above-described problems, a lantern shade according to the present invention is a lantern shade that is attached to a lamp that irradiates one direction at the time of use, and functions as a lantern that illuminates the surroundings, and surrounds a light emitting portion of the lamp A mounting portion for mounting in such a manner that one end of the mounting portion is joined to the mounting portion and extends in one direction on the opposite side of the light emitting portion, and a cylindrical enclosure portion, and the enclosure portion And an end portion for reflecting the light beam emitted from the light emitting portion, and the enclosure portion is foldable, and when the mounting portion is mounted on the lamp It is configured to be self-supporting.

  Since the lantern shade according to the present invention includes the mounting portion, it can be detachably mounted surrounding the light emitting portion of the lamp. Therefore, it can be carried separately from the lamp when not in use, and can be attached to the lamp and perform a lantern function only when in use. Since the enclosure part is formed so that one end is joined to the mounting part and extends in one direction opposite to the light emitting part, it is possible to follow the light beam emitted from the light emitting part simply by attaching the mounting part to the light emitting part. An enclosure can be arranged. Since the surrounding part has a cylindrical shape, it can surround the light emitted from the light emitting part. The other end of the enclosure is provided with an end portion that reflects the light beam emitted from the light emitting unit, so that the light beam that has passed through the enclosure from the light emitting unit to the end portion is reflected to enclose the enclosure. You can make the enclosure light up. Furthermore, since the enclosure can be folded, when carrying the lantern shade separately from the lamp when not in use, it can be folded and carried compact. Furthermore, since the enclosure portion is configured to be able to stand on its own when the mounting portion is mounted on the lamp, it can be erected from the light emitting portion without specially forming a self-standing bone member. For this reason, a normal lamp for irradiating in one direction can be used as one that fulfills the lantern function by the self-supporting enclosure that emits light.

  In the lantern shade according to the present invention, it is also preferable that the mounting portion is configured to be annular and contractible.

  In this preferred embodiment, the mounting portion is configured to be annular and contractible, so that the outer shape around the light emitting portion is rectangular or circular, and the size of the mounting portion can be contracted. If it is any size, the mounting portion can be attached in close contact with the light emitting portion. Accordingly, it is difficult for the lantern shade to drop off from the lamp during use, and the light from the light emitting portion can be guided to the enclosure portion without being lost unnecessarily.

  In the lantern shade according to the present invention, it is also preferable that the surrounding portion is formed by stitching a plurality of rectangular sheets together, and the stitching direction is directed from the mounting portion toward the end portion.

  In this preferable aspect, since the enclosure part is comprised by stitching together a plurality of rectangular sheets, the cylindrical enclosure part can be easily formed. Further, since the stitching directions of the plurality of rectangular sheets are directed from the mounting portion toward the end portion, the portion where the rectangular sheets are stitched together serves as a bone for allowing the cylindrical enclosure to stand on its own. Furthermore, the portion where the rectangular sheets are stitched together can be configured to ensure flexibility when folded while serving as a bone when the enclosure is self-supporting. It is possible to achieve both the role of causing the lamp to perform the lantern function.

  Moreover, in the lantern shade according to the present invention, it is also preferable that the end portion is configured so that the reflectance on the inside is higher than that on the outside.

  As described above, the light beam emitted from the light emitting unit passes through the cylindrical enclosure and reaches the end. Therefore, in this preferred embodiment, the internal reflectance of the end portion is increased as compared with the external reflectance, so that the light emitted from the light emitting portion can be reliably reflected inside and emitted.

  In the lantern shade according to the present invention, it is also preferable that the end portion is configured to reflect the light emitted from the light emitting unit toward the enclosure.

  In this preferred embodiment, the end portion is configured to reflect the light emitted from the light emitting portion toward the enclosure portion, so that the light emitted from the light emitting portion can be surely directed to the enclosure portion. Therefore, the light emitted from the light emitting unit can be used without waste, and the lamp can perform the lantern function.

  In the lantern shade according to the present invention, it is also preferable that the end portion is configured so as to form a substantially conical shape from a portion joined to the enclosure portion toward the mounting portion.

  In this preferred embodiment, the end portion is configured as a substantially conical shape, and the substantially conical shape is formed so as to be directed from the portion joined to the enclosure portion toward the mounting portion. An end portion is formed so as to extend outward from the light emitting portion. Therefore, since the light beam irradiated from the light emitting part hits the vicinity of the apex of the substantially conical shape, the entire light beam can be surely changed to the surrounding part.

  According to the present invention, a lantern shade that can also perform a lantern function by being mounted on a lighting device that performs a lamp function, can be configured to be lightweight, and can be stored compactly while exhibiting the lamp function. Possible lantern shades can be provided.

  The light emitting unit HLc incorporates a light emitter such as a lamp, and is configured to be turned on or off by an operation of the switch HLd. The light emission mode of the light emitting unit HLc may be configured to be switched between blinking lighting and continuous lighting, or may be configured to be switched between one having a weak emission intensity and one having a strong emission intensity.

  The lantern shade of the present embodiment is for using the headlamp HL having the lamp function for illuminating one direction as a lantern. The lantern shade of this embodiment will be described with reference to FIGS. FIG. 2 is a perspective view showing how the lantern shade LS according to the present embodiment is attached to the headlamp HL shown in FIG. FIG. 3 is a perspective view showing a state in which the lantern shade LS according to the present embodiment is attached to the headlamp HL shown in FIG.

  As shown in FIG. 2, the lantern shade LS includes a mounting portion LSa, a surrounding portion LSb, and an end portion LSc. The mounting portion LSa is a portion that is disposed so as to surround the light emitting portion HLc of the headlamp HL, and for mounting the lantern shade LS to the headlamp HL. The mounting portion LSa is configured to be annular and contractible. Specifically, it is formed by covering an annular member formed of a rubber-like stretchable material with a surface material such as cloth or durable paper.

  The surrounding portion LSb is a cylindrical portion that is formed so that one end LSba is joined to the mounting portion LSa and extends in one direction opposite to the light emitting portion HLc. The enclosure LSb is transparent or translucent, and is formed of a flexible and firm material. The enclosure portion LSb is configured to be foldable and capable of being self-supporting when the attachment portion LSa is attached to the headlamp HL.

  The end portion LSc is a portion that is joined to the other end LSbb of the enclosure portion LSb and reflects the light emitted from the light emitting portion HLc radially.

  As shown in FIG. 3, when the lantern shade LS is attached to the headlamp HL, the mounting portion LSa is spread along the outer periphery of the lamp main body HLa, and the mounting portion LSa is aligned along the outer periphery of the lamp main body HLa. Install. When the lantern shade LS is attached to the headlamp HL in this way, the light emitted from the light emitting portion HLc travels in the enclosure LSb and hits the end LSc. The light beam that hits the end portion LSc is blocked by the end portion LSc, changes its traveling direction, and returns at least to the inside of the lantern shade LS. The enclosure portion LSb is illuminated by the returned light, and the light is irradiated to the side through the enclosure portion LSb.

  Next, members constituting the lantern shade LS will be described with reference to FIG. FIG. 4 is an exploded perspective view of the lantern shade LS according to the present embodiment. As shown in FIG. 4, the surrounding portion LSb is configured by four rectangular sheets LSbp, LSbp, LSbp, and LSbp. The rectangular sheets LSbp, LSbp, LSbp, and LSbp are made of a thin fabric in order to increase light transmission. This fabric is subjected to a treatment such as urethane coating in order to achieve firmness and stiffness for making the lantern shade LS self-supporting.

  The rectangular sheet LSbp has a pair of long sides 10, 12, a short side 14 connecting one end of the long side 10 and one end of the long side 12, and a short connecting the other end of the long side 10 and the other end of the long side 12. Side 16. Adjacent rectangular sheet LSbp and rectangular sheet LSbp are formed by stitching one long side 10 and the other long side 12 into one rectangular sheet. In this way, the four rectangular sheets LSbp, LSbp, LSbp, and LSbp are stitched together to form an enclosure LSb. Therefore, the stitching direction in which the four rectangular sheets LSbp, LSbp, LSbp, and LSbp are stitched together is directed from the mounting portion LSa to the end portion LSC.

  A mounting portion LSa is attached to the short sides 14, 14, 14, and 14 of the four rectangular sheets LSbp, LSbp, LSbp, and LSbp stitched together. Further, end portions LSc are attached to the short sides 16, 16, 16, 16 of the rectangular sheets LSbp, LSbp, LSbp, and LSbp stitched together.

  The end portion LSc is configured by a conical portion LSca and a stationary ring LScb. The conical portion LSca has a vertex 20, a side surface 22, and a base 24. The conical portion LSca is attached to the short sides 16, 16, 16, 16 of the rectangular sheets LSbp, LSbp, LSbp, and LSbp that are stitched together with the bases 24 facing the mounting portion LSa. The conical portion LSca and the short sides 16, 16, 16, 16 of the rectangular sheets LSbp, LSbp, LSbp, and LSbp stitched together are fixed by a fixed ring LScb.

  When the members shown in FIG. 4 are connected as described above, a lantern shade LS is obtained as shown in FIG. As shown in FIG. 5, the stitched portions LSs of the rectangular sheets LSbp, LSbp, LSbp, and LSbp are formed so as to go from the mounting portion LSa toward the end portion LSc.

  Subsequently, the end portion LSc will be described with reference to FIG. FIG. 6 is a schematic cross-sectional view showing how the light beam L emitted from the headlamp HL travels when the lantern shade LS is attached to the headlamp HL shown in FIG. The end portion LSc is configured such that the reflectance of the inner side 221 is higher than that of the outer side 222. The light beam L emitted from the light emitting unit HLc travels toward the end portion LSc. The light beam L hits the inner side 221 of the end portion LSc. Since the outer side 222 and the inner side 221 constitute the side surface 22 of the conical portion LSca, the light beam L that has hit the inner side 221 changes its direction toward the surrounding portion LSb. As described above, the end portion LSc is configured to reflect the light beam L emitted from the light emitting portion HLc toward the surrounding portion LSb.

  As described above, the lantern shade LS according to the present embodiment is a lantern shade for functioning as a lantern that illuminates the surroundings by being attached to the headlamp HL that irradiates one direction during use. The lantern shade LS has a mounting portion LSa for mounting so as to surround the light emitting portion HLc of the headlamp HL, and one end LSba of the mounting portion LSa is joined to the mounting portion LSa, and extends in one direction opposite to the light emitting portion HLc. And an end portion LSc that is joined to the other end LSbb of the enclosing portion LSb and reflects the light beam L emitted from the light emitting portion HLc. The enclosure part LSb is configured to be foldable and to be able to stand on its own when the attachment part LSa is attached to the headlamp HL.

  Since the lantern shade LS includes the mounting portion LSa, the lantern shade LS can be detachably mounted surrounding the light emitting portion HLc of the headlamp HL. Therefore, it can be carried separately from the headlamp HL when not in use, and can be mounted on the headlamp HL and perform a lantern function only when in use. The enclosure portion LSb is formed so that one end LSba is joined to the mounting portion LSa and extends in one direction opposite to the light emitting portion HLc, so that the mounting portion LSa is simply attached so as to surround the light emitting portion HLc. The surrounding portion LSb can be disposed along the light beam L emitted from the light emitting portion HLc.

  Since the enclosing portion LSb has a cylindrical shape, it can enclose light emitted from the light emitting portion HLc. The other end LSbb of the enclosure part LSb is provided with an end LSc that reflects the light beam L emitted from the light emitting part HLc, so that the end part LSc is passed from the light emitting part HLc through the enclosure LSb. By blocking the light beam L, it can go to the enclosure part LSb and light up the enclosure part LSb. Furthermore, since the enclosure part LSb can be folded, when carrying the lantern shade LS separately from the headlamp HL when not in use, it can be folded and carried compact. Furthermore, since the enclosure portion LSb is configured to be able to stand by itself when the mounting portion LSa is mounted on the headlamp HL, the enclosure portion LSb is erected from the light emitting portion HLc without specially forming a self-standing bone member. Can be made. Therefore, since the light-enclosed enclosure LSb is self-supporting, a normal headlamp HL for irradiating in one direction can be used as one that performs a lantern function.

  In the present embodiment, the mounting portion LSa is configured to be annular and contractible, so that the outer shape around the light emitting portion HLc (the outer shape of the lamp body HLa) is rectangular or circular. The mounting portion LSa can be attached in close contact with the lamp main body HLa around the light emitting portion HLc regardless of the size of the mounting portion LSa that can be contracted. Therefore, the lantern shade LS is not easily dropped from the headlamp HL during use, and the light from the light emitting portion HLc can be guided to the enclosure portion LSb without wastefully escaping.

  Moreover, in this embodiment, since the enclosure part LSb is comprised by stitching together the several rectangular sheet LSbp, the cylindrical enclosure part LSb can be formed easily. Further, since the stitching direction of the plurality of rectangular sheets LSbp is directed from the mounting portion LSa toward the end portion LSc, the portion of the rectangular sheets LSbp stitched together (sewing allowance) serves as a column for allowing the cylindrical enclosure LSb to stand on its own. Fulfill. Furthermore, the portion where the rectangular sheets LSbp are sewn together can be configured to ensure flexibility when folded while serving as a bone when the enclosure LSb is self-supporting. Both the portability and the role of causing the headlamp HL to perform the lantern function can be achieved.

  As described above, the light beam L emitted from the light emitting unit HLc passes through the cylindrical enclosure LSb and reaches the end LSc. Therefore, in the present embodiment, the reflectance inside the end portion LSc is increased as compared with the outside reflectance, so that the light emitted from the light emitting portion HLc can be reliably reflected and emitted inside.

  Further, in the present embodiment, the end portion LSc is configured as a substantially conical shape, and the substantially conical shape is formed so as to be directed from the portion joined to the enclosing portion LSb toward the mounting portion LSa. An end portion LSc is formed so that 20 is directed toward the mounting portion LSa, that is, the light emitting portion HLc, and extends outward therefrom. Accordingly, since the light beam L emitted from the light emitting portion HLc hits the vicinity of the substantially conical apex, the light beam L as a whole can be reliably redirected to the surrounding portion LSb.
