Description

  The present invention relates to an electronic candle.

  Electronic candles are being sold as an alternative to candles that light fires in matches. The electronic candle, for example, is provided in the internal body so as to protrude above the upper end of the case body, the cylindrical internal body inserted into the case body, and the case body, and can be turned on when energized. And a lighting part. In this electronic candle, a battery for lighting the lighting part is attached to the internal body, and the battery can be replaced by removing the internal body from the case body.

  The electronic candle has a locking structure that can prevent the internal body from unintentionally coming out of the case body. For example, a convex portion is formed on the inner peripheral surface of the case body, and a shallow groove in which the convex portion enters the lower outer peripheral surface of the inner body is formed (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 9-7411

  However, in the locking structure in which the convex part of the case body is pushed into the shallow groove of the internal body, when the internal body is inserted into and removed from the case body, the lower part of the shallow groove on the outer peripheral surface of the internal body is It will add a great amount of power to overcome. This requires a large force when inserting / removing the internal body, and the internal body cannot be easily inserted / removed. In addition, the locking portion may be damaged by repeating such insertion and removal.

  The main object of the present invention is to provide an electronic candle capable of facilitating the attaching / detaching operation of the internal body with respect to the case body and suppressing the breakage of the engaging portion between the case body and the internal body.

  In order to solve the above-described problems, an electronic candle according to a first aspect of the present invention includes a cylindrical case body that extends in the vertical direction and is open at least at the upper end side, and a columnar shape that is inserted into the case body from the upper end of the case body. An inner body, and a lighting part that is provided at the upper end of the inner body and protrudes upward from the upper end of the case body, is shaped like a flame, and is turned on by energization. An electronic candle, provided on a part of the inner peripheral surface of the case body in the circumferential direction, protruding inward in the radial direction, and extending in the circumferential direction on the outer peripheral surface of the inner body, the protruding portion The case body has a shape in which a circumferential groove portion that suppresses the dropout of the internal body relative to the case body by entering and a part of a lower protrusion of the circumferential groove portion that forms the circumferential groove portion is cut out. Against Wherein the protruding portion is provided with a passage portion can pass when connecting or disconnecting the internal body.

  According to the first invention, when the internal body is attached to the case body, the protrusion of the case body can reach the circumferential groove through the passage part of the internal body, and the internal body rotates in that state. By doing so, the projecting portion enters the circumferential groove portion, and the projecting portion and the lower ridge portion can be locked. Here, when the internal main body is attached to and detached from the case body, it is not necessary to apply a large force so that the protruding portion gets over the lower protrusion, so that the internal main body can be attached and detached easily. it can. In addition, since the inner body can be attached and detached without the protruding portion getting over the lower ridge portion, the protruding portion does not break or deform by repeatedly getting over the lower ridge portion.

  In a second aspect of the invention, the circumferential groove portion is provided with a first standing portion that rises from the bottom surface of the circumferential groove portion in a part of the circumferential direction of the outer peripheral surface of the internal body, and the first standing portion is The inner body is prevented from rotating with respect to the case body by abutting against the protruding portion in a state of entering the circumferential groove portion, and one end side of the passage portion in the circumferential direction of the inner body Is arranged.

  According to the second invention, when the protruding portion is in the state of entering the circumferential groove portion, if the protruding portion exists on the opposite side of the passing portion across the first standing portion in the circumferential direction of the internal main body. The rotation angle of the internal body necessary for releasing the locking between the protruding portion and the lower ridge is ensured as much as possible. Thereby, it can suppress that a protrusion part comes out of a circumferential groove part through a passage part. That is, it can suppress that an internal main body falls out from a case body unintentionally.

  According to a third aspect of the present invention, a second upright portion is provided on the opposite side of the circumferential groove portion from the bottom surface of the circumferential groove portion across the first upright portion, and the second upright portion is provided. The portion is in contact with the projecting portion in a state of entering the circumferential groove portion, thereby restricting the rotation of the internal body relative to the case body, and the height dimension in the radial direction of the internal body Is smaller than the first upright portion.

  When the first standing part is provided adjacent to one end of the passage part in the circumferential direction of the internal body, the first standing part can regulate the rotation of the internal body with respect to the case body in one of the circumferential directions, Cannot be regulated. In this regard, according to the third aspect of the invention, the operator rotates the inner body with such a force that the protruding portion can get over the second upright portion, so that the protruding portion becomes the first upstanding portion and the second upright portion. Can exist between. When the projecting portion exists between the first upright portion and the second upright portion, the rotation of the inner body is restricted by the first upright portion on one side in the circumferential direction and restricted by the second upright portion on the other side. it can. For this reason, it can suppress more reliably that a protrusion part comes out of a circumferential groove part through a passage part by restricting rotation of an internal main body by the 1st standing part and the 2nd standing part.

  According to a fourth aspect of the present invention, a pair of the passage part and the first upright part are provided with the center of the inner body interposed therebetween.

  When a pair of passage portions are provided on the lower ridge portion, as compared with the case where there is one passage portion, the protrusion can easily come out of the circumferential groove portion through the passage portion by rotating the internal body with respect to the case body. Conceivable. Therefore, according to the fourth aspect of the present invention, when the protruding portion is in the circumferential groove portion, if the protruding portion exists on the opposite side of the passing portion across the first standing portion, the protruding portion is The rotation angle of the internal body necessary for exiting the circumferential groove portion through the passage portion is set to approximately 180 degrees. For this reason, while the alignment operation | work with a protrusion part and a passage part can be facilitated, it can suppress that a protrusion part comes out of a circumferential groove part through a passage part.

  Note that it is preferable that a plurality of the passing portions are provided side by side in the circumferential direction of the inner body at the lower ridge portion, even if the passage portions are not paired across the center of the inner body. In this case, the angle at which the internal body is rotated with respect to the case body when performing the alignment operation between the projecting portion and the passage portion can be made smaller than when only one passage portion is provided. Thereby, when attaching / detaching the internal main body to / from the case body, it is possible to facilitate the alignment operation between the protruding portion and the passing portion.

  In a fifth aspect of the invention, the lower protrusion is provided at the lower end of the inner main body, and the inner main body is formed of a synthetic resin material and a pair of semi-cylindrical main body forming members are superimposed on each other. Thus, the passage portion is disposed at a boundary portion of the pair of main body forming members in the lower ridge portion.

  According to the fifth aspect, since the lower protrusion is disposed at the lower end of the internal body, the protrusion can be disposed closer to the lower end of the case body. Thereby, when inserting an internal main body in a case body, the inconvenience that a protrusion part is caught on the outer peripheral surface of an internal main body can be avoided.

  Here, when the lower ridge portion is disposed at the lower end of the internal main body, the main body using a mold is formed when the formation portion of the lower ridge portion is divided into a plurality of passage portions in the main body forming member. When forming the forming member, there is a concern that the synthetic resin material poured into the mold is less likely to reach the formation portion of the lower protrusion. On the other hand, according to 5th invention, since the passage part is arrange | positioned in the boundary part of main body formation members, the formation part of a lower protrusion part can be made into one site | part. Thereby, at the time of shaping | molding of the lower side ridge part using a metal mold | die, it can suppress that a synthetic resin material becomes difficult to spread to the formation part of a lower side ridge part.

  In a sixth aspect of the present invention, a base for supporting the case body in a state in which the case body is inserted from above is provided in an insertion portion formed by recessing the upper surface downward, and a ring-like shape is provided at a lower portion of the base. The weight member is built in, and the weight member is arranged so that the axis of the through hole of the weight member extends vertically.

  According to the sixth aspect, since the weight member is disposed along the lower peripheral surface of the pedestal, it is possible to prevent the internal main body and the case body from falling together with the pedestal. Thereby, it can suppress that an internal main body falls from a case body at the time when the base fell.

  The seventh invention is characterized in that the weight member is a nut. According to the seventh aspect, since the weight member is a commercially available nut, a configuration in which the pedestal is difficult to fall down can be realized at low cost.

It extends in the up-down direction in a state of being stretched over. The upright portions 45, 46 contact the protrusion 31 of the case body 11 in a state where the protrusion 31 of the case body 11 enters the circumferential groove 32, so that the internal body 14 rotates with respect to the case body 11. It is possible to regulate.

  The first upright portions 45 of the upright portions 45 and 46 are provided in pairs with the center of the internal body 14 in the same manner as the passage portion 41, and are respectively provided on one end side of the passage portion 41 in the circumferential direction of the internal body 14. Has been placed. The first upright portion 45 is disposed at the boundary between the lower ridge portion 33 and the passage portion 41, and is connected to the end of the lower ridge portion 33. In the radial direction of the inner main body 14, the height of the first upright portion 45 from the bottom surface 32 b of the circumferential groove portion 32 is the same as that of the lower protrusion 33. In this case, the protruding portion 31 of the case body 11 does not get over the first upright portion 45 in the circumferential direction of the internal main body 14, and the rotation of the internal main body 14 is restricted by contacting the first upright portion 45. To do.

  Similarly to the passage portion 41 and the first standing portion 45, a pair of the second upright portions 46 are provided across the center of the internal body 14, and are connected to the lower ridge 33. The second upright portion 46 is disposed at an intermediate position of the lower ridge portion 33 in the circumferential direction of the internal body 14, and is on the opposite side of the passage portion 41 with the first upright portion 45 interposed therebetween. The second upright portion 46 is separated from the first upright portion 45, and the separation distance is larger than the width dimension of the protruding portion 31 of the case body 11 in the circumferential direction of the internal body 14. In the radial direction of the inner main body 14, the height of the second upright portion 46 from the bottom surface 32 b of the circumferential groove portion 32 is smaller than that of the first upright portion 45. In this case, an external force that rotates the internal body 14 relative to the case body 11 is applied to slightly deform the internal body 14, the case body 11, etc. It is possible to get over the second upright portion 46 in the circumferential direction of 14.

  In the lower ridge 33, an inclined portion 48 having a radially outer surface inclined toward the passage 41 is provided at the end opposite to the first standing portion 45 with the passage 41 interposed therebetween. Yes. The inclined portion 48 has a height dimension with respect to the bottom surface 32b of the circumferential groove portion 32 that is gradually reduced toward the passage portion 41 in the radial direction of the inner body 14, and the height dimension of the end surface on the passage portion 41 side is the case body. 11 is equal to or smaller than the distance between the protruding portion 31 and the bottom surface 32b of the circumferential groove portion 32 of the internal main body 14.

  Here, an operation procedure when the internal body 14 is inserted into the case body 11 will be described with reference to FIGS. 4B and 5. FIG. 5 is a view for explaining a procedure for allowing the protruding portion 31 of the case body 11 to enter the circumferential groove portion 32 of the internal body 14. In addition, in FIG. 5, the figure which looked at the cross-sectional view of the internal main body 14 and the surrounding groove part 32 vicinity in case body 11 from the downward | lower direction is shown.

  First, the inner main body 14 is inserted into the case body 11, and the lower end surface of the inner main body 14 (the lower surface of the lower ridge portion 33) is brought into contact with the upper surface of the protruding portion 31 of the case body 11. 5A, the internal body 14 is rotated with respect to the case body 11, and the passage portion 41 of the internal body 14 is aligned with the protruding portion 31 of the case body 11. . Here, since a pair of passage portions 41 are provided across the center of the internal main body 14, the alignment can be performed by rotating the internal main body 14 at most approximately 180 degrees.

  As shown in FIG. 5B, when the alignment of the passage part 41 and the protrusion part 31 is performed, the protrusion part 31 passes the passage part 41 in the vertical direction, so that the internal body 14 is moved to the case body 11. Can be moved further downward. In this case, the protruding portion 31 is directly above the passing portion 41.

  Thereafter, by rotating the internal body 14 in a direction in which the first upright portion 45 moves away from the projecting portion 31, the lower projecting ridge portion 33 is positioned so as to overlap the projecting portion 31 vertically as shown in FIG. Move. In this case, the upward movement of the internal main body 14 is restricted by the lower protruding portion 33 and the protruding portion 31 being locked.

  Here, even when the projecting portion 31 cannot pass through the passage portion 41 in the vertical direction and the lower end of the projecting portion 31 is in the passage portion 41, when the inner body 14 is rotated, the projecting portion 31 is It moves to the upper side of the lower ridge portion 33 relative to the lower ridge portion 33 so as to follow the radially outer side surface of the inclined portion 48. That is, the protrusion 31 is brought into contact with the radially outer surface of the inclined portion 48, whereby the lower protrusion 33 is guided to the lower side of the protrusion 31.

  In the inclined portion 48, the height dimension of the circumferential groove portion 32 with respect to the bottom surface 32b is preferably set such that the upper end is lower than the lower end. In this case, the protrusion 31 is relatively easy to move to the upper side of the lower protrusion 33 along the radially outer surface of the inclined portion 48. That is, it becomes easy for the lower protrusion 33 to move to the lower side of the protrusion 31.

  After the lower protrusion 33 is moved to a position where it overlaps the protrusion 31, the second standing part 46 comes into contact with the protrusion 31 when the internal body 14 is further rotated. The internal body 14 is rotated by applying an external force over the portion 46, and the protruding portion 31 is disposed between the first upright portion 45 and the second upright portion 46 as shown in FIG. In this state, the rotation of the inner main body 14 in one direction in the circumferential direction is restricted by the contact between the first standing portion 45 and the protruding portion 31, and the rotation of the inner main body 14 in the other direction is controlled by the second rising portion 46 and the protruding portion 31. It is regulated by the contact. In this case, the inner main body 14 is not rotated unintentionally with respect to the case body 11. That is, the state in which the protruding portion 31 enters the circumferential groove portion 32 is not unintentionally released.

  When pulling out the internal body 14 from the case body 11, the internal body 14 is rotated by applying an external force so that the second upright portion 46 gets over the protrusion 31, and the upper protrusion 33 has an upper surface on the upper surface of the lower protrusion 33. While the lower surface is in contact, the position of the passage portion 41 with respect to the protrusion portion 31 is aligned, and the inner body 14 is moved upward so that the protrusion portion 31 passes the passage portion 41. Here, the alignment work between the projecting portion 31 and the passage portion 41 when the internal body 14 is extracted is performed by rotating the internal body 14 at least approximately 180 degrees in the same manner as the alignment work when the internal body 14 is inserted. Alignment can be performed.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In the electronic candle 10 in which the inner body 14 is prevented from coming out of the case body 11 by the protrusion 31 of the case body 11 entering the circumferential groove 32 of the inner body 14, the lower protrusion of the circumferential groove 32. Since the passage portion 41 is provided at 33, the protruding portion 31 can be moved in and out of the circumferential groove portion 32 through the passage portion 41 without having to get over the lower protrusion 33. In this case, since it is not necessary to apply such a large force that the protruding portion 31 gets over the lower protruding portion 33, the attaching / detaching operation of the inner main body 14 with respect to the case body 11 can be facilitated. Here, in the configuration in which the protruding portion 31 rides over the lower ridge 33 without passing through the passage portion 41, there is a concern that the protruding portion 31 and the lower ridge 33 may be damaged or deformed when getting over. However, the concern can be eliminated when the protruding portion 31 passes through the passage portion 41. Therefore, the attaching / detaching operation of the internal body 14 with respect to the case body 11 can be facilitated, and breakage of the locking portion between the case body 11 and the internal body 14 can be suppressed.

  Since a pair of the passage portions 41 are provided in the lower ridge portion 33, when the protrusion portion 31 is taken in and out of the circumferential groove portion 32, the passage portion 41 and the passage portion 41 can be rotated by rotating the inner body 14 at a maximum of approximately 180 degrees. It is possible to perform alignment with the protruding portion 31. In this case, for example, the rotation angle of the inner main body 14 required for alignment can be reduced compared to a configuration in which only one passage portion 41 is provided in the lower protrusion 33, thereby facilitating the alignment operation. it can. On the other hand, in the configuration in which only one passage portion 41 is provided, it is necessary to rotate the inner main body 14 at a maximum of approximately 360 degrees for alignment.

  Since a pair of protrusions 31 are provided in the case body 11, two locking portions between the lower protrusions 33 and the protrusions 31 can be secured on the outer peripheral side of the inner body 14. Therefore, it is possible to suppress the inner main body 14 from being inclined with respect to the case body 11 in a state where the protruding portion 31 is locked to the lower protruding portion 33. For example, when only one protrusion 31 is provided, there is a concern that there is one locking portion, and the locking portion serves as a fulcrum and the internal body 14 is inclined with respect to the case body 11.

  On the upper side of the lower ridge 33 (the circumferential groove portion 32 of the internal main body 14), the protrusion 31 of the case body 11 abuts on the first upright portion 45 to restrict the rotation of the internal main body 14. In this case, if the protruding portion 31 exists on the opposite side of the first standing portion 45 across the passage portion 41, the inner body 14 is substantially omitted in order to align the protruding portion 31 and the passage portion 41. It is necessary to rotate 180 degrees. For this reason, even if the internal main body 14 rotates a little, it can suppress that the protrusion part 31 comes out of the circumferential groove part 32 through the passage part 41 unintentionally.

  On the upper side of the lower ridge 33, the protrusion 31 of the case body 11 abuts against the second upstanding portion 46, so that the rotation of the internal body 14 to the side opposite to the first upstanding portion 45 is restricted. In this case, if the protruding portion 31 exists between the first standing portion 45 and the second standing portion 46, the second standing state that the inner body 14 rotates in a direction in which the protruding portion 31 approaches the passing portion 41. It can be regulated by the portion 46. For this reason, it can suppress more reliably that the protrusion part 31 comes out of the circumferential groove part 32 through the passage part 41 unintentionally by restricting that the internal main body 14 rotates itself.

  When the internal body 14 is attached to the case body 11, after the alignment between the protruding portion 31 and the passing portion 41 is performed, the protruding portion 31 enters the passing portion 41 without passing through the passing portion 41. When the inner main body 14 is rotated as it is, the protruding portion 31 is guided to the upper side of the lower protruding portion 33 so as to follow the radially outer surface of the inclined portion 48 of the lower protruding portion 33. For this reason, even if the insertion amount of the internal main body 14 with respect to the case body 11 is somewhat insufficient after the alignment of the protruding portion 31 and the passage portion 41 is performed, the lower ridge portion 33 is placed below the protruding portion 31. Can be moved. That is, it is possible to facilitate the work of causing the protruding portion 31 to enter the circumferential groove portion 32 from the passage portion 41.

  Since the lower ridge 33 (circumferential groove portion 32) is disposed at the lower end of the internal body 14, the protrusion 31 of the case body 11 is the lower ridge when the internal body 14 is inserted into the case body 11. Even 33 need only pass up and down. For this reason, it can avoid that the protrusion part 31 is caught in the battery mounting part 27 grade | etc., Of the internal main body 14, and the internal main body 14 cannot be inserted in the inside of the case body 11. FIG.

  Since the passage portion 41 is disposed so as to straddle the boundary between the pair of main body forming members 14a in the inner main body 14, the portion forming the lower protrusion 33 may be a single portion in the main body forming member 14a. it can. Thereby, when shape | molding the main body formation member 14a with a metal mold | die, it can suppress that a synthetic resin material becomes difficult to spread to the formation part of the lower side protrusion part 33. FIG. In addition, since the lower ridge 33 is disposed at the end of the main body forming member 14a, it is particularly effective to prevent the synthetic resin material from being easily distributed.

  Since the weight member 22 is incorporated so as to extend along the lower peripheral surface of the pedestal 13, the internal body 14 and the case body 11 can be prevented from falling together with the pedestal 13. Thereby, it can suppress that the protrusion part 31 comes out of the surrounding groove part 32 through the passage part 41, and the internal main body 14 slips out from the case body 11 at the time when the base 13 fell. Moreover, since the weight member 22 is a commercially available nut, it is possible to realize a configuration in which the pedestal 13 is unlikely to fall down at a low cost.
