  As shown in these drawings, the opening / closing mechanism 1 of the present embodiment is configured to include a cover 10, a base 20, an opening / closing member 40, a guide member 50, and a biasing member 60. Further, the opening / closing mechanism 1 includes mounting screws 71 and 72a to 72c for mounting each member.

<Cover 10>
The cover 10 is connected to the base 20. The cover 10 has an opening 11 at a position corresponding to the opening 21 of the base 20. The opening / closing member 40 is arranged above the opening 11. The opening / closing member 40 linearly moves along the longitudinal direction of the cover 10 so as to open / close the opening 11. As shown in FIGS. 1 to 4, the surface of the cover 10 on the opening / closing member 40 side has a curved shape having a curved surface in the longitudinal direction. The cover 10 has convex portions 12a and 12b protruding toward the opening / closing member 40 side.

<Base 20>
The base 20 is connected to the cover 10. The base 20 has an opening 21 at a position corresponding to the opening 11 of the cover 10. A guide member 50 is incorporated in the base 20. A peripheral region of the second guide hole 23, which is a surface of the base 20 facing the cover 10, has a curved shape having a curved surface similar to that of the cover 10.

  The base 20 has penetrating elongated first guide holes 22a and 22b on its side surface substantially perpendicular to the direction in which it overlaps with the cover 10. The first guide holes 22a and 22b have the same shape and are formed at opposite positions. The first guide holes 22a and 22b are shaped along the curved surfaces of the upper surface of the cover 10 and the upper surface of the base 20. Therefore, when the guide member 50 is incorporated in the base 20, the guide member 50 can always move while maintaining a constant distance between the upper surface of the cover 10 and the upper surface of the base 20. The 1st guide holes 22a and 22b are examples of 1 composition of the "1st guide part" of the present invention.

  The guide pins 51a and 52a of the guide member 50 are inserted into the first guide hole 22a, and the guide pins 51b and 52b of the guide member 50 are inserted into the first guide hole 22b. Stoppers 22a1 and 22b1 are formed in the first guide holes 22a and 22b, respectively, and contact the guide pins 51a and 51b at one end of the movement range of the guide member 50, respectively. Further, stoppers 22a2 and 22b2 are formed, which are in contact with the guide pins 52a and 52b at the other end of the movement range of the guide member 50, respectively. These stoppers 22a1, 22a2, 22b1 and 22b2 restrict the movement of the guide member 50 at both ends of the movement range. The stopper 22b2 is not shown in the figure because it is not shown, but has a configuration corresponding to the stopper 22a2 of the guide hole 22a. The guide pins 51a, 52a, 51b, and 52b are examples of the "guided portion" in the present invention. Further, both end portions of the first guide holes 22a and 22b are examples of the "stopper" of the present invention.

  The base 20 has an elongated second guide hole 23 penetrating therethrough on the upper surface facing the cover 10. That is, the second guide hole 23 is formed at a position substantially parallel to the direction in which the base 20 and the cover 10 overlap. The second guide hole 23 is linearly formed in parallel with the moving direction of the opening / closing member 40. The guide member-side spring hooking portion 53 of the guide member 50 is inserted into the second guide hole 23 to linearly guide the guide member 50. The 2nd guide hole 23 is an example of 1 composition of the "2nd guide part" of the present invention.

  In the above description, the configuration in which both ends of the first guide holes 22a and 22b function as the stoppers 22a1, 22a2, 22b1 and 22b2 has been described as an example. However, by contacting the second guide hole 23 with the guide member 50 at one end and the other end of the movement range of the guide member 50, the second guide hole 23 serves as a stopper that restricts the movement of the guide member 50 at both ends of the movement range. You may comprise. In this case, both ends of the second guide hole 23 serve as an example of the "stopper" of the present invention.

  The base 20 is connected to the cover 10 by mounting screws 72a to 72c.

  The base 20 has a base-side spring hooking portion 24 protruding in a column shape toward the cover 10 side. The first arm portion 61 of the biasing member 60 is hooked on the base-side spring hooking portion 24. The base-side spring hook portion 24 of the base 20 is positionally fixed. The base-side spring hook portion 24 is an example of the "first hook portion" in the present invention.

<Opening / closing member 40>
The opening / closing member 40 has a screw hole 42 into which a mounting screw 71 for mounting to the guide member 50 is inserted. The opening / closing member 40 is linearly movable with respect to the cover 10 and the base 20 so as to open and close the opening 11 of the cover 10 and the opening 21 of the base 20, and is held by the guide member 50. Further, as shown in FIGS. 3 and 4, the opening / closing member 40 has linear recesses 41a and 41b at positions facing the protrusions 12a and 12b of the cover 10 along the opening / closing direction, respectively. The height of the convex portions 12a and 12b of the cover 10 is higher than the depth of the concave portions 41a and 41b. Therefore, the opening / closing member 40 is linearly movable by arranging the recesses 41a and 41b so as to mesh with the protrusions 12a and 12b of the cover 10, respectively. You can move smoothly without touching the upper surface of the.

<Guide member 50>
The guide member 50 is incorporated in the base 20 and connected to the opening / closing member 40. More specifically, the mounting screw 71 penetrates the through hole 54 of the guide member 50 and is inserted into the screw hole 42 of the opening / closing member 40, thereby connecting the guide member 50 and the opening / closing member 40. The guide member 50 moves as the opening / closing member 40 moves. That is, the guide member 50 is integrated with the opening / closing member 40 and is linearly movable with respect to the cover 10 and the base 20.

  The guide member 50 has a guide member-side spring hook portion 53 that protrudes in a column shape toward the cover 10. The second arm portion 62 of the biasing member 60 is hooked on the guide member side spring hooking portion 53. Since the guide member side spring hook portion 53 is provided on the guide member 50, it moves linearly with respect to the cover 10 and the base 20 as the guide member 50 moves. The guide member side spring hooking portion 53 moves in the second guide hole 23 as described above, but the distance from the base side spring hooking portion 24 becomes the shortest at substantially the center of both end positions where the guide member 50 moves. It is like this. The guide member-side spring hook portion 53 is an example of the "second hook portion" in the present invention.

  In the present embodiment, an example in which the opening / closing member 40 and the guide member 50 are configured as separate members has been described, but the opening / closing member 40 and the guide member 50 may be configured as a single member. In the present invention, a configuration including the opening / closing member 40 and the guide member 50 may be referred to as a “lid member”.

<Biasing member 60>
The biasing member 60 is a torsion spring having a first arm portion 61 and a second arm portion 62. The first arm portion 61 of the biasing member 60 is hooked on the base-side spring hooking portion 24. The second arm portion 62 of the biasing member 60 is hooked on the guide member side spring hooking portion 53. Since the biasing member 60 is attached so that the inner angle is smaller than the inner angle between the first arm portion 61 and the second arm portion 62 in the unloaded state, the biasing member 60 applies a biasing force in the direction in which the inner angle expands.

  In FIG. 6, the biasing member 60 in three states is shown as 60a, 60b, and 60c. The biasing members 60a, 60b, and 60c are the biasing member 60a in a state where the opening / closing member 40 opens the openings 11 and 21, and the biasing member 60a in a state where the opening / closing member 40 closes the openings 11 and 21. 60c and the urging member 60b in the intermediate position between them. Corresponding to the biasing members 60a, 60b, and 60c in these three states, the second arm portion 62 of the biasing member 60 locked to the guide member-side spring hook portion 53 (53a, 53b, and 53c). Are also located at three locations 62a, 62b and 62c.

  In the state of the biasing member 60a, the opening / closing member 40 opens the openings 11 and 21. In this state, the biasing member 60a biases the guide member 50 in contact with the stoppers 22a2 and 22b2 in the opening direction (the right side in FIG. 6) with respect to the base 20, whereby the guide member 50 moves. The position is stable. That is, the opening / closing member 40 connected to the guide member 50 is stable with the openings 11 and 21 opened. When the opening / closing member 40 is pushed in the closing direction with the fingertip from this state, the state of the biasing member 60b is passed through to the state of the biasing member 60c.

  In the state of the biasing member 60c, the opening / closing member 40 closes the openings 11 and 21. In this state, the biasing member 60c biases the guide member 50 in contact with the stoppers 22a1 and 22b1 in the closing direction (left side in FIG. 6) with respect to the base 20, whereby the guide member 50 moves. The position is stable. That is, the opening / closing member 40 connected to the guide member 50 is stable with the openings 11 and 21 closed. When the opening / closing member 40 is pushed in the opening direction from this state by the fingertip, the state of the biasing member 60b is passed through to the state of the biasing member 60a.

  In the state of the biasing member 60b, the opening / closing member 40 is located at a substantially intermediate position between the opening / closing positions. In this state, the urging member 60b urges the two spring hooking portions 24 and 53 only in the direction orthogonal to the lengthwise direction of the second guide hole 23, so that the guide member 50 is urged in both directions. It is in a state where it does not gather power. From this state, when the opening / closing member 40 slightly moves in the opening direction, the biasing member 60b applies a biasing force to the guide member 50 in the opening direction. Conversely, when the opening / closing member 40 slightly moves in the closing direction, the biasing member 60b applies a biasing force to the guide member 50 in the closing direction. That is, the biasing member 60 has the direction in which the biasing force applied to the opening / closing member 40 is the opening direction and the closing direction with the position where the distance between the base side spring hooking portion 24 and the guide member side spring hooking portion 53 is the shortest as a boundary. It changes with the direction.

It has a movable structure.

  Further, in the opening / closing mechanism 1 of the present embodiment, as described above, the base 20 has the first guide holes 22a and 22b and the second guide hole 23, and these guide holes determine the moving range of the guide member 50. It functions as a stopper. With this configuration, the movement range of the lid members 40 and 50 can be determined by any of the first guide holes 22a and 22b of the base 20 and the second guide hole 23.

  Further, in the opening / closing mechanism 1 of the present embodiment, as described above, the base 20 forms the first guide holes 22a and 22b and the second guide hole 23 as through holes, so that the heater can be downsized. It has a structure with excellent durability.

  Further, the opening / closing mechanism 1 of the present embodiment is configured to urge the guide member 50 in the opening / closing direction by the urging member 60 as described above. This allows the opening / closing member 40 to smoothly open and close the opening. Further, the opening / closing member 40 is stably held at both ends of the opening / closing. In addition, since the user has a suitable biasing force, the user can feel the opening and closing when opening and closing, and the opening and closing member 40 can be opened and closed comfortably.

  Further, the opening / closing mechanism 1 of the present embodiment has a configuration in which the opening / closing member 40 is stably held at both ends of opening / closing as described above. Further, the biasing direction is changed with the position where the distance between the first arm portion 61 and the second arm portion 62 is the shortest (the position in the state of the biasing member 62b in FIG. 6) as a boundary. The user can open and close comfortably and smoothly with a click.

  Further, in the opening / closing mechanism 1 of the present embodiment, as described above, the base side spring hooking portion 24 is arranged so as to face the guide member side spring hooking portion 53 at a substantially intermediate position of the movement range of the guide member 50. There is. In other words, the base-side spring hooking portion 24 is arranged so that the distance between the base-side spring hooking portion 24 and the base-side spring hooking portion 24 is the shortest, at the approximate center of both end positions where the guide member 50 moves. As a result, the biasing force (force) applied to the opening / closing member 40 and the guide member 50 becomes substantially the same in each of the opening operation and the closing operation, so that the opening / closing operation can be made smoother and more comfortable. ing.

The member 50 (500) is linearly guided. Here, since the guide member side spring hooking portion 53 is a cylindrical shaft, the guide member 50 (500) having the guide member side spring hooking portion 53 has the guide member side spring hooking portion with respect to the base 20 (200). Rattling occurs in the direction of rotation about the axis of 53. In order to suppress this rattling, the above-mentioned configuration is adopted.

  That is, when the guide member 500 is located near the end portion in the closing direction (left direction in the drawing) in the moving region (state of FIG. 9), each is formed at a position away from the guide member side spring hook portion 53, The closing direction end portion 55a1 of the first plate-shaped member 55a is in contact with the closing direction portion 25a1 of the first inner surface portion 25a, and the closing direction end portion 55b1 of the second plate-shaped member 55b is the closing direction portion of the second inner surface portion 25b. It is in contact with 25b1. On the other hand, when the guide member 500 is located in the vicinity of the end in the opening direction (rightward in the drawing) in the movement region (state in FIG. 10), there is a gap between the first plate member 55a and the first inner surface portion 25a. Is formed, and a gap is formed between the second plate-shaped member 55b and the second inner surface portion 25b. Therefore, the guide member 500 receives a pressing force in a direction perpendicular to the moving direction when it is located near the end of the moving region in the closing direction, and this pressing force is applied when it is located near the end of the moving region in the closing direction. It will be canceled. Accordingly, when the guide member 500 is located in the vicinity of the end in the moving direction in the closing direction, the rotation of the guide member 500 around the guide member-side spring hook portion 53 is restricted and rattling is suppressed, and the guide member 500 is suppressed. When is located in a region other than the vicinity of the end in the closing direction in the moving region, the guide member 500 can be smoothly moved in the moving direction.

  In this modified example, by adopting the above-described configuration, it is possible to prevent the rattling from occurring in the state where the opening / closing member 40 connected to the guide member 500 closes the opening 11, and the closed state. It has a stable structure.

<3. Supplementary items>
Heretofore, a specific description has been given of the embodiment of the present invention. The above description is merely one embodiment, and the scope of the present invention is not limited to this one embodiment, and is broadly construed to a range that a person skilled in the art can understand.

  In the opening / closing mechanism 1 of the above-described embodiment, the first guide holes 22a and 22b are used as stoppers in order to determine the movement range of the guide member 50 and the opening / closing member 40, but the invention is not limited to such a configuration. .. That is, the second guide hole 23 may be used, or the combination of the first guide holes 22a and 22b and the second guide hole 23 may function as a stopper. Further, the guide member 50 and the opening / closing member 40 are restricted in movement, for example, at one end of the moving range thereof, a part of the guide member 50, a part of the opening / closing member 40, or the guide member side spring hook portion 53 abuts on the stopper. At the other end of the movement range, a stopper may come into contact with a part of the guide member 50, a part of the opening / closing member 40, or the guide member-side spring hook portion 53 to restrict movement. .. That is, the stopper can be configured to restrict movement of the guide member 50 and the opening / closing member 40 by contacting different members at one end and the other end of the movement range.

  Further, in the embodiment, the torsion spring is used as the biasing member 60, but it may be replaced with another type of spring or another biasing member. However, the configuration using the torsion spring is preferable because it is advantageous for downsizing the heater and can stably operate.

  Further, in the embodiment, the guide member-side spring hooking portion 53 is arranged so that the distance between the guide member-side spring hooking portion 53 and the base-side spring hooking portion 24 becomes the shortest at a substantially intermediate position of the movement range of the guide member 50. The position at which the distance between the portion 53 and the base-side spring hooking portion 24 becomes the shortest is not limited to the substantially intermediate position except the both end positions of the movement range of the guide member 50, and may be an intermediate position of the movement range.

  In the embodiment, the surface of the cover 10 that faces the opening / closing member 40, the surface of the base 20 that faces the cover 10, and the first guide holes 22a and 22b have the same curved surface. Although the shape is used, the invention is not limited to such a configuration. That is, at least the surface of the cover 10 and the shape of the first guide hole may have the same curved shape. However, when the surface of the base 20 has the same shape, the urging member 60 arranged on the surface of the base 20 on the side facing the cover 10 moves along the curved surface, and thus the guide member 50 and the guide member 50. 40 is preferable because it can be moved more smoothly and comfortably.

  Further, in the embodiment, when the guide member 50 comes into contact with the stopper, the open / closed position is held by the biasing force of the biasing member, but the configuration is not limited to this. That is, the guide member 50 or the opening / closing member 40 and the base may be provided with a concave portion and a convex portion, respectively, and the concave portion and the convex portion may be elastically fitted to each other when abutting on the stopper. However, it is preferable to use the biasing member because it has excellent durability and can be opened and closed smoothly and comfortably.

  In addition, in the embodiment, the two guide portions 22a, 22b, and 23 have a long hole shape penetrating therethrough, but the present invention is not limited to such a configuration. That is, the guide portion may have a rail-like shape that projects over the moving region or a groove. Further, only one of the two guide portions may have such a shape. However, the through hole is preferable because the heater can be downsized and can operate with excellent durability.

  The present invention can be applied not only to the opening / closing mechanism for the cigarette heater but also to other opening / closing mechanisms.

  The present invention is suitably applied as an opening / closing mechanism that is opened / closed by a user.
