2. Modifications
3. Supplemental Examples
1. EmbodimentsAn opening-closing assembly according to an embodiment of the present invention is used for a heater for heating a heated tobacco product as a cover for an opening through which a heated tobacco product is inserted. The opening-closing assembly according to the embodiment of the present invention includes two guides for smooth opening and closing and an opening-closing member stably supported by an urging member at the two ends of a movable range in the opening and closing directions. This structure will be described in detail below.
As shown in the drawings, the opening-closing assembly 1 according to the present embodiment includes a cover 10, a base 20, an opening-closing member 40, a guide member 50, and an urging member 60. Also, the opening-closing assembly 1 includes attachment screws 71 and 72a to 72c for attaching the members together.
Cover 10The cover 10 is joined to the base 20. The cover 10 has an opening 11 at a position corresponding to an opening 21 in the base 20. The opening-closing member 40 is located over the opening 11. The opening-closing member 40 moves linearly in the longitudinal direction of the cover 10 to open and close the opening 11. As shown in
The base 20 is joined to the cover 10. The base 20 has the opening 21 at a position corresponding to the opening 11 in the cover 10. The guide member 50 is assembled on the base 20. A surface of the base 20 surrounding a second guide slot 23 and facing the cover 10 is curved in conformance with the surface of the cover 10.
The base 20 has first guide slots 22a and 22b in the side surfaces substantially perpendicular to the direction in which the base 20 and the cover 10 overlap. The first guide slots 22a and 22b are elongated through-holes. The first guide slots 22a and 22b have the same shape and are at positions opposite to each other. The first guide slots 22a and 22b each have a shape that conforms to the curved upper surface of the cover 10 and the curved upper surface of the base 20. This allows the guide member 50, when assembled on the base 20, to move while maintaining a constant interval from the upper surface of the cover 10 and from the upper surface of the base 20. The first guide slots 22a and 22b are examples of a first guide in an aspect of the present invention.
The first guide slot 22a receives guide pins 51a and 52a on the guide member 50. The first guide slot 22b receives guide pins 51b and 52b on the guide member 50. The first guide slots 22a and 22b include stoppers 22a1 and 22b1, which come into contact with the guide pins 51a and 51b respectively at one end of the movable range of the guide member 50. At the other end of the movable range of the guide member 50, stoppers 22a2 and 22b2 are located and can come into contact with the guide pins 52a and 52b respectively. The stoppers 22a1, 22a2, 22b1, and 22b2 restrict the movement of the guide member 50 at the two ends of the movable range. Although the stopper 22b2 is not illustrated and its reference numeral is not shown, the stopper 22b2 has the structure corresponding to the structure of the stopper 22a2 in the guide slot 22a. The guide pins 51a, 52a, 51b, and 52b are examples of a guided portion in an aspect of the present invention. Also, the two ends of the first guide slots 22a and 22b are examples of a stopper in an aspect of the present invention.
The base 20 includes the second guide slot 23 in the upper surface facing the cover 10. The second guide slot 23 is an elongated through-hole. In other words, the second guide slot 23 is formed at a position substantially parallel to the direction in which the base 20 and the cover 10 overlap. The second guide slot 23 extends linearly parallel to the movement direction of the opening-closing member 40. A guide member spring holder 53 on the guide member 50 is received in the second guide slot 23, and the second guide slot 23 guides the guide member 50 linearly. The second guide slot 23 is an example of a second guide in an aspect of the present invention.
In the above example, the two ends of the first guide slots 22a and 22b function as the stoppers 22a1, 22a2, 22b1, and 22b2. In another example, the second guide slot 23 may function as a stopper that restricts the movement of the guide member 50 at the two ends of the movable range with the guide member 50 in contact with the second guide slot 23 at the two ends of the movable range of the guide member 50. In this structure, the two ends of the second guide slot 23 are examples of a stopper in an aspect of the present invention.
The base 20 is joined to the cover 10 with the attachment screws 72a to 72c.
The base 20 includes a base spring holder 24 that protrudes in a cylindrical shape toward the cover 10. The urging member 60 includes a first arm 61 hooked and held to the base spring holder 24. The base spring holder 24 on the base 20 is fixed in position. The base spring holder 24 is an example of a first holder in an aspect of the present invention.
Opening-Closing Member 40The opening-closing member 40 has a screw hole 42 into which the attachment screw 71 is inserted for attaching the opening-closing member 40 to the guide member 50. The opening-closing member 40 is supported by the guide member 50 in a manner linearly movable relative to the cover 10 and the base 20 to open and close the opening 11 in the cover 10 and the opening 21 in the base 20. Also, as shown in
The guide member 50 is assembled on the base 20 and joined to the opening-closing member 40. More specifically, the guide member 50 and the opening-closing member 40 are joined with the attachment screw 71 placed through a through-hole 54 in the guide member 50 and into the screw hole 42 in the opening-closing member 40. The guide member 50 moves together with the opening-closing member 40. In other words, the guide member 50 is integral with the opening-closing member 40 and linearly movable relative to the cover 10 and the base 20.
The guide member 50 includes the guide member spring holder 53 that protrudes in a cylindrical shape toward the cover 10. The urging member 60 includes a second arm 62 hooked and held to the guide member spring holder 53. With the guide member spring holder 53 on the guide member 50, the guide member spring holder 53 moves, together with the guide member 50, linearly relative to the cover 10 and the base 20. The guide member spring holder 53 moves within the second guide slot 23 as described above, with the shortest distance from the base spring holder 24 being at substantially the center between the two ends of the movable range of the guide member 50. The guide member spring holder 53 is an example of a second holder in an aspect of the present invention.
The present embodiment is an example in which the opening-closing member 40 and the guide member 50 are separate members. In another embodiment, the opening-closing member 40 and the guide member 50 may be a single member. In embodiments of the present invention, the opening-closing member 40 and the guide member 50 together may be referred to as a lid.
Urging Member 60The urging member 60 is a torsion spring including the first arm 61 and the second arm 62. The first arm 61 of the urging member 60 is hooked and held to the base spring holder 24. The second arm 62 of the urging member 60 is hooked and held to the guide member spring holder 53. The urging member 60 is attached to have a smaller internal angle between the first arm 61 and the second arm 62 than an internal angle between the arms in an unloaded state. The urging force acts in a direction to increase the internal angle.
In
In the state of the urging member 60a, the opening-closing member 40 opens the openings 11 and 21. In this state, the guide member 50, in contact with the stoppers 22a2 and 22b2, is urged relative to the base 20 in the opening direction (right side in
In the state of the urging member 60c, the opening-closing member 40 closes the openings 11 and 21. In this state, the guide member 50, in contact with the stoppers 22a1 and 22b1, is urged relative to the base 20 in the closing direction (left side in
In the state of the urging member 60b, the opening-closing member 40 is at a substantially middle position between the open and closed positions. In this state, the guide member 50 is not urged in either direction, as the urging force from the urging member 60b acts on the two spring holders 24 and 53 simply in the direction orthogonal to the length direction of the second guide slot 23. When the opening-closing member 40 is moved in this state slightly in the direction to open the openings 11 and 21, the urging force from the urging member 60b acts on the guide member 50 in the opening direction. When the opening-closing member 40 is moved in this state slightly in the direction to close the openings 11 and 21, the urging force from the urging member 60b acts on the guide member 50 in the closing direction. In other words, the urging force from the urging member 60 can change to act on the opening-closing member 40 in the opening direction or the closing direction at the position where the base spring holder 24 has a shortest distance from the guide member spring holder 53.
As described above, the opening-closing assembly 1 according to the present embodiment includes the lids 40 and 50 guided by the first guide slots 22a and 22b and the second guide slot 23. The opening can thus be smoothly open and closed.
Also, as described above, the opening-closing assembly 1 according to the present embodiment includes the first guide slots 22a and 22b at substantially right angles to the direction in which the base 20 and the cover 10 overlap and the second guide slot 23 substantially parallel to the direction in which the base 20 and the cover 10 overlap. The heater can thus be more compact, and the opening and closing operations can be smooth. Further, the interval between the cover 10 and the lids (the opening-closing member 40 and the guide member 50) is maintained constant by the first guide slots 22a and 22b, and the lids (the opening-closing member 40 and the guide member 50) can be easily guided linearly by the second guide slot 23.
As described above, the opening-closing assembly 1 according to the present embodiment has the first guide slots 22a and 22b in a curved shape conforming to the shape of the cover 10. Thus, in examples in which the cover has a curved surface, the structure allows smooth and stable movement.
Also, as described above, the opening-closing assembly 1 according to the present embodiment includes the base 20 having the first guide slots 22a and 22b and the second guide slot 23. These guide slots function as stoppers that determine the movable range of the guide member 50. The movable range of the lids 40 and 50 can thus be determined using the first guide slots 22a and 22b and the second guide slot 23 in the base 20.
Also, as described above, the opening-closing assembly 1 according to the present embodiment includes the first guide slots 22a and 22b and the second guide slot 23 formed as through-holes in the base 20. The heater can thus be more compact, and high durability can be achieved.
Further, as described above, the opening-closing assembly 1 according to the present embodiment includes the guide member 50 urged in the opening and closing directions by the urging member 60. The opening can thus be smoothly open and closed with the opening-closing member 40. Also, the opening-closing member 40 is stably supported at the two ends of the movable range in the opening and closing directions. Further, the urging force allows the user to have tactual feedback from opening or closing of the opening-closing member 40. This allows the opening-closing member 40 to be open and closed comfortably.
As described above, the opening-closing assembly 1 according to the present embodiment includes the opening-closing member 40 stably supported at the two ends of the movable range in the opening and closing directions. Also, the urging direction can change at the position where the first arm 61 has a shortest distance from the second arm 62 (the position of the urging member 62b in
As described above, in the opening-closing assembly 1 according to the present embodiment, the base spring holder 24 is located opposite to the guide member spring holder 53 at a substantially middle position of the movable range of the guide member 50. In other words, the base spring holder 24 is located to have the shortest distance from the guide member spring holder 53 at substantially the center between the two ends of the movable range of the guide member 50. The urging force (amount of force) that acts on the opening-closing member 40 and the guide member 50 is substantially the same for the opening operation and the closing operation. This further improves the smoothness and the comfort of the opening and closing operations.
As described above, the opening-closing assembly 1 according to the present embodiment includes the guide member spring holder 53 also functioning as a guided portion in the second guide slot 23 in the base 20. The heater can thus be more compact.
As described above, the opening-closing assembly 1 according to the present embodiment includes the lids 40 and 50 joined with the attachment screw 71. The assembly can be simple, although the heater has a complex design.
As described above, in the opening-closing assembly 1 according to the present embodiment, the surface of the opening-closing member 40 facing the cover 10 is in conformance with the cover 10. The cover and the opening-closing member can have an integral design, allowing a more sophisticated design.
Example UseA modification of the above embodiment will now be described. An opening-closing assembly according to the modification has the same structure as the assembly according to the embodiment except a base 200 and a guide member 500 that replace the base 20 and the guide member 50. The modification will be described focusing on its differences from the embodiment, without the components common to the above embodiment being described.
The guide member 500 includes a first plate 55a and a second plate 55b that extend in the movement direction substantially parallel to each other. The first plate 55a supports the guide pins 51a and 52a. The second plate 55b supports the guide pins 51b and 52b. In other words, the guide pins 51a and 52a are erect on the first plate 55a, and the guide pins 51b and 52b are erect on the second plate 55b.
The guide pins 52a and 52b are joined with a guide pin joint 52c. The guide pins 52a and 52b and the guide pin joint 52c are integral as a shaft that extends in a direction perpendicular to the movement direction of the guide member 500.
Base 200The base 200 includes a first inner surface 25a at a position facing the first plate 55a. Also, the base 200 includes a second inner surface 25b at a position facing the second plate 55b. The first inner surface 25a and the second inner surface 25b are slightly tilted with each other, rather than being parallel to each other. The distance between the first inner surface 25a and the second inner surface 25b is greater in the closing direction (left in the figure) than in the opening direction (right in the figure).
As described in the embodiment, the guide member spring holder 53 on the guide member 50 (500) is received in the second guide slot 23 in the base 20 (200), and the second guide slot 23 guides the guide member 50 (500) linearly relative to the base 20 (200). In this example, with the guide member spring holder 53 being a cylindrical shaft, the guide member 50 (500) including the guide member spring holder 53 may have play in the rotation direction about the axial center of the guide member spring holder 53 relative to the base 20 (200). The structure described above can reduce this play.
More specifically, when the guide member 500 is adjacent to the end of the movable range in the closing direction (left in the figure) (the state in
The structure in the present modification can have less play when the opening 11 is closed with the opening-closing member 40 joined to the guide member 500, thus stabilizing the closed state.
3. Supplemental ExamplesThe embodiment of the present invention is described in detail above. The scope of the present invention is not limited to the above embodiment but is construed broadly within the scope understandable by those skilled in the art.
In the opening-closing assembly 1 according to the embodiment described above, the first guide slots 22a and 22b are used as stoppers to determine the movable range of the guide member 50 and the opening-closing member 40. However, the present invention is not limited to this structure. In some embodiments, the second guide slot 23 may function as the stopper, or a combination of the first guide slots 22a and 22b and the second guide slot 23 may function as the stopper. In other embodiments, a portion of the guide member 50, a portion of the opening-closing member 40, or the guide member spring holder 53 may come into contact with the stopper to restrict the movement of the guide member 50 and the opening-closing member 40 at one end of the movable range, and a portion of the guide member 50, a portion of the opening-closing member 40, and the guide member spring holder 53 may come into contact with the stopper to restrict the movement at the other end of the movable range. In other words, in other embodiments, the movement of the guide member 50 and the opening-closing member 40 may be restricted by the stopper coming into contact with different members at either end of the movable range.
The urging member 60 is a torsion spring in the embodiment. In some embodiments, the urging member 60 may be a different spring or a different urging member. The torsion spring as the urging member 60 can downsize the heater and enables stable operation.
In the embodiment, the distance between the guide member spring holder 53 and the base spring holder 24 is the shortest at a substantially middle position of the movable range of the guide member 50. In some embodiments, the guide member spring holder 53 and the base spring holder 24 may be at the shortest distance between them at any other midway position of the movable range of the guide member 50, excluding the ends of the movable range.
In the embodiment, the surface of the cover 10 facing the opening-closing member 40 and the surface of the base 20 facing the cover 10 have a curved surface in conformance with the first guide slots 22a and 22b. However, the present invention is not limited to this structure. In other words, at least the surface of the cover 10 and the first guide slot may have a curved shape in conformance with each other. However, with the urging member 60 on the surface of the base 20 facing the cover 10 moving along the curved surface, the surface of the base 20 in conformance with the curved surface may allow the guide member 50 and the opening-closing member 40 to move more smoothly and comfortably.
In the embodiment, when the guide member 50 is in contact with the stopper, the open and closed positions are supported under the urging force from the urging member. However, the present invention is not limited to this structure. The guide member 50 or the opening-closing member 40 may have a recess, and the base may have a protrusion. The recess and the protrusion may elastically engage with each other when the guide member 50 or the opening-closing member 40 is in contact with the stopper. However, the urging member can achieve high durability and smooth and comfortable opening and closing operations.
In the embodiment, the two guides 22a and 22b and the guide 23 are elongated through-holes. However, the present invention is not limited to this structure. In other words, the guides may have an overhanging rail extending in the movable range or may be a groove. Also, one of the two guides may have such a shape. However, the structure with the through-holes can downsize the heater and achieve highly-durable operation.
The present invention may be applied to an opening-closing assembly for applications other than a tobacco heater.
