Description

  The present invention relates to a portable ashtray that houses cigarette butts.

Japanese Patent Laid-Open No. 11-18747 Japanese Patent Application Laid-Open No. 2001-78745 discloses a case main body, an inner lid inserted into an upper opening of the case main body, and an upper opening of the case main body while closing a sucking mouth insertion opening of the inner lid. And a portable ashtray in which the case lid is coupled to the case main body by a hinge so as to be rotatable in a direction to open and close the upper opening of the case main body.

  When trying to put a cigarette into a portable ashtray, hold the cigarette butt with the right hand finger and hold the portable ashtray with the left hand, so a portable ashtray that can open the case lid with the portable ashtray with only one hand (left hand) is desirable. It is. However, since the portable ashtray of Patent Document 1 has a structure in which the case lid is opened by rotating the ring while holding the knob attached to the tip of the case body with fingers (0017), the portable ashtray can be held with only one hand. Moreover, it is difficult to open the case lid. The portable ashtray of Patent Document 1 has a structure in which the case lid is opened by pressing the locking piece protruding from the side surface of the case body along the slit and the case lid is opened (0011, 0012). The case lid can be opened by supporting the portable ashtray and operating the locking piece with the finger of one hand. However, when the portable ashtray is in a pocket or handbag, or when the portable ashtray is taken out, the locking piece gets caught on something and the case lid opens, and the ash and butts of the portable ashtray come out in the pocket or handbag. It may end up.

  It is an object of the present invention to provide a portable ashtray that can be held with one hand and the case lid can be opened, and that the case lid cannot be accidentally opened when it is in a pocket or a handbag. To do.

(1) a case main body, an inner lid inserted into the upper opening of the case main body, and a case lid that closes the upper end opening of the case main body and closes the upper end of the case main body. A portable ashtray that is coupled to the case body by a hinge so as to be pivotable in a direction to open and close the upper opening of the case body, and an opening spring member on the hinge pivots the case lid to open the upper opening. In
The case lid includes an engagement member in which a small-diameter trunk is continuous at the leading end that has a large diameter from the tip toward the rear;
The case body can move in a direction opposite to the direction in which the case lid contacts the small-diameter trunk of the engaging member when the upper opening of the case body is closed, and is a pair of engagements facing each other. A retaining member, and a restraining spring member that is interposed between the pair of locking members and forces the pair of locking members in a direction to contact the small-diameter trunk;
When the operation end of each of the pair of locking members protrudes from each of the opposing side surfaces of the case body in the direction of contact with the small-diameter trunk of the engagement member, and when there is simultaneous pressing of both operation ends, A pair of locking members move in the opposite direction away from the small diameter trunk and the case lid opens;
A portable ashtray characterized by that.

  According to this, when closing the case lid, the head of the engaging member pushes the pair of locking members in the reverse direction (opening direction) against the forcing force of the restraining spring member and passes between the members. When passing, the pair of locking members abut against the small-diameter trunk of the engaging member. That is, the pair of locking members restrains (locks) the case lid. In this restrained state, that is, when the case lid is closed, the pair of locking members are opposed to each other in the direction in which they come into contact with the small-diameter trunk of the engaging member (locking direction), and the restraining spring member Since it is forced in the contact direction, even if only one locking member is pushed in the reverse direction and moves in the reverse direction (opening direction), the pushing force compresses the restraint spring member and the restraint spring member Pushes the other locking member in the locking direction, so that the other locking member remains in the locked position where it comes into contact with the small-diameter trunk. The case lid is not unlocked and the case lid does not open.

  Support the portable ashtray with the middle finger, ring finger, and little finger of the left hand, and simultaneously push the operation ends of the pair of locking members with the thumb and forefinger so that the space above the case lid is wrapped with the palm, that is, simultaneously in the opposite direction ( By pushing in the opening direction, the restraining spring member is compressed and the pair of locking members move in the opposite direction (opening direction). That is, both the locking members are separated from the small-diameter trunk of the engaging member, and the passage between the pair of locking members at the head of the engaging member (case lid opening) becomes possible. At this time, the case lid opens and jumps up due to the repulsive force of the opening spring member, but it does not fully open when it hits the palm (continuous part between the thumb and the index finger). In this state, the butt can be inserted into the butt insertion port of the inner lid. Alternatively, by shifting the holding position by the fingers to the case lid, the case lid is in the fully open position shown in FIG. In this state or after placing the case body on the table, the butts can be inserted into the buttocks insertion opening of the inner lid.

  Thus, since the portable ashtray can be held with only one hand and the case lid can be opened, the operability is good. Not only the movement in the reverse direction (opening direction) of only one of the pair of locking members, but the locking (locking) at the head of the engaging member is not released, so the safety of closing the case lid is high.

  (2) The side wall of the case main body and the case lid where the operation end portions of the pair of locking members protrude has a recess for receiving the belly of the tip of the finger; the portable ashtray according to (1) above .

  According to this, the portable ashtray is supported by the middle finger, ring finger, and little finger of the left hand, and the space above the case lid is covered with the palm, and the thumb is placed on one of the opposite dents and the index finger is placed on the other, and the operation inside the dent is performed. By pushing the end part into the case body at the same time, the case lid is automatically opened and hits the palm (continuous part between the thumb and the index finger) and the full opening is stopped. Finger contact for operating the operation end portions of the pair of locking members can be performed easily and smoothly.

  (3) The protrusion at the tip of the operation end of the pair of locking members does not reach or reach the side surface with the recess; The portable ashtray according to (2) above. According to this, since an object does not easily hit the operation end, it is difficult to cause erroneous opening.

  (4) The engaging member is on the opposite side of the end of the case lid where the hinge is located; the portable ashtray according to (3) above. Accordingly, the backlash of the case lid with respect to the case body can be reduced.

  (5) The case body has an engagement port into which the top of the engagement member enters when the case lid closes the upper opening of the case body, and the engagement port is located below the pair of locking members. The portable ashtray according to any one of (1) to (4) above. According to this, when the case lid is closed, the leading end of the engaging member enters the engaging port, and the engaging port suppresses play in the direction (x, y) orthogonal to the protruding direction (z) of the engaging member. be able to.

  (6) There is a finger hooking projection at a position on the side surface of the inner lid above the upper opening of the case body, and an inner surface of the side wall of the case lid has a recess for receiving the projection; The portable ashtray according to any one of (5). According to this, since the finger is easily hooked on the inner lid, the inner lid can be easily pulled out.

  (7) On the side surface of the inner lid, there is a minute protrusion at the lower part of the side surface that reduces contact friction with the case main body; The portable ashtray according to (1) to (6) above. According to this, the frictional resistance when the inner lid is pulled out from the case main body is small and easy to pull out.

  (8) The inner bottom surface of the case main body has a plurality of protrusions or grooves distributed in a direction parallel to the rotation center axis of the hinge and perpendicular to the rotation center axis; The portable ashtray according to any one of (1) to (7). According to this, it is easy to erase the burning cigarette in the case body.

At the lower part of each side surface of the opposite long side of the inner lid 6, there are two minute projections 63 (two opposing ones) for reducing sliding friction caused by surface contact with the inner side surface of the case body 2 at the lower side surface. ) And 64 (two facing each other), and these are point-contacted with the inner surface of the case body 2 to reduce sliding friction, and the inner lid 6 can be easily attached to and detached from the case body 2 (insertion / extraction). is there. On the inner bottom of the case main body 2, a large number of protrusions 22 are formed in parallel with the central axis (x) of rotation of the hinge 3, and are distributed in the y direction perpendicular to the central axis (x). These ridges 22 are effective in extinguishing fires that scrape off the sparked carbonized portion at the tip of the butts. A groove may be formed instead of the ridge 22.

  FIG. 3A shows an enlarged view of the lower part of the middle plate 7 at the tip of the case body 2. The case body 2 has a pair of partition walls 23 and 24 parallel to the short side wall thereof, and these are a part of the case body 2 (continuous integration with the bottom plate and the outer wall of the body 2). The upper end surfaces of the pair of partition walls 23, 24 are lower than the upper end of the outer wall of the case body 2 by an amount slightly larger than the thickness of the intermediate plate 7. A portion of the outer wall of the case body 2 between the partition walls 23 and 24 has a groove into which the pair of locking members 81 and 82 are fitted, and its bottom surface is more than the upper end surfaces of the partition walls 23 and 24. The thickness is slightly larger than the thickness of the locking members 81, 82.

  Between the pair of partition walls 23 and 24, there are three beams that are continuous with them, and the left and right beams therein are moved in the x direction by the pair of locking members 81 and 82. Upper protrusions 25 and 26 for guiding are formed. At the upper end surface of the central beam 27, an engagement port 28 through which the head 42 of the engagement member 41 can enter exactly is opened. Between the beam 24 and the short side outer wall, there are two beams 31 and 32 which are continuous with them, and female screw holes 33 and 34 for receiving screws 71 and 72 penetrating the intermediate plate 7 are opened. ing. As shown in FIGS. 1 and 2, when the intermediate plate 7 is fixed to the case body with screws 71 and 72, the screws 71 and 72 are screwed to the female screw holes 33 and 34, and the engagement port 28 is , Just below the through hole 73 of the intermediate plate 7.

  A pair of locking members 81, 82 are placed on three beams between the pair of partition walls 23, 24, and the upper protrusions 25, 26 that have entered the guide holes 83, 84 of the locking members 81, 82. Thus, movement in the x direction is restricted, and the movement range is restricted.

  In FIG. 3B, only a pair of locking members 81 and 82 is taken out, and the position is shifted in the height direction z. The locking members 81 and 82 have the same shape, and L-shaped (saddle-shaped) ends 85 and 86 on the opposite side to the operation end projecting outward from the outer wall of the case body 2 serve as locking hooks. Yes.
