[Technical field]

[0001] The present disclosure relates to a handle device and fittings. [Background technology]

[0002] For example, in the case of fittings, the opening and closing of a sliding window is performed by rotating a handle. The handle is exposed to the interior even when not in use, which causes problems with appearance and also causes problems in that it becomes an obstacle when opening and closing curtains.

[0003] Patent document 1 discloses a handle device in which the end of a handle is rotatably attached to a handle base, two notch-shaped engagement portions are formed at the end of the handle at a predetermined interval in the rotation direction, a spring is provided on the handle base which presses against the end of the handle, and the spring is provided with a protrusion-shaped engagement portion which selectively engages with one of the two engagement portions of the handle.

[0004] In the handle device disclosed in Patent Document 1, the handle can be folded when not in operation, and after the spring is deflected due to interference between the spring protrusion and the notched engagement portion and adjacent protrusions, the spring protrusion engages with the notched engagement portion, generating a clicking force to maintain the operating position and the folded position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the handle device and fittings of the present disclosure will be described with reference to Fig. 1 to Fig. 15. The following embodiment shows one aspect of the present disclosure, does not limit the disclosure, and can be modified as desired within the scope of the technical idea of ​​the present disclosure. In addition, in the following drawings, the scale of each structure is different from the actual structure in order to make each configuration easier to understand.

[0011] As shown in Fig. 1, the fitting 100 has an opening / closing window 101. As an example, the opening / closing window 101 is a vertical sliding window whose door edge opens and closes centered in the vertical direction.

[0012] The opening and closing window 101 is provided in an opening W formed in a wall of a building. The opening and closing window 101 comprises a frame body 1, a screen 2, and an opening and closing device 3. The screen 2 is housed within the frame body 1. The screen 2 is arranged along a vertical plane. The screen 2 can be opened and closed from a state in which the inside of the frame body 1 is closed to a state in which the door tip is open toward the outdoors.

[0013] In the following description, the direction connecting the outdoor side and the indoor side is referred to as the indoor / outdoor direction. Among the view directions perpendicular to the indoor / outdoor direction, the horizontal direction is referred to as the left / right direction. With regard to the left / right direction, the directions as seen from the indoor side are referred to as the right side and the left side. The vertical direction connecting the upper side and the lower side is referred to as the up / down direction.

[0014] The frame body 1 is formed in a four-sided frame shape and has an upper frame 11, a lower frame 12, and a pair of vertical frames 13.

[0015] The upper frame 11 is located at the upper side of the frame body 1 and extends in the left-right direction. As shown in Fig. 2, the upper frame 11 has a metal upper frame 11A arranged on the outdoor side and a resin upper frame 11B arranged on the indoor side.

[0016] The lower frame 12 is located on the lower side of the frame body 1 and extends in the left-right direction. The lower frame 12 has a metal lower frame 12A arranged on the outdoor side and a resin lower frame 12B arranged on the indoor side. The vertical frame 13 extends in the up-down direction. The vertical frame 13 connects both ends of the upper frame 11 in the left-right direction to both ends of the lower frame 12 in the left-right direction.

[0017] The shoji screen 2 has a frame 20 and glass 29. The frame 20 is formed in a rectangular frame shape. The frame 20 has an upper frame 21, a lower frame 22, and a vertical frame 23. The upper frame 21 is located on the upper side of the frame 20 and extends in the left-right direction. The lower frame 22 is located on the lower side of the frame 20 and extends in the left-right direction. The vertical frame 23 extends in the up-down direction. The vertical frame 23 connects both ends of the upper frame 21 in the left-right direction to both ends of the lower frame 22 in the left-right direction.

[0018] The upper frame 21, the lower frame 22 and the vertical frame 23 are formed with a glass holding groove 26 that is U-shaped in cross section and recessed away from the end face of the glass 29. The end face of the glass 29 is accommodated in the glass holding groove 26 via a glazing channel 27 that has a roughly U-shaped cross section. The glass holding groove 26 and the glazing channel 27 in the vertical frame 23 are not shown in the figure. The shoji screen 2 is guided by an arm provided on the left hanging side by the opening and closing device 3, so that the right door end side of the shoji screen 2 can be opened and closed.

[0019] 3 and 4, the opening and closing device 3 has an input unit 30 and an output unit 40. The input unit 30 receives a driving force for opening and closing the opening window 101. The output unit 40 outputs the driving force received from the input unit 30 to the opening window 101.

[0020] The input unit 30 is fixed from the indoor side to a surface facing the indoor side of the resin lower frame 12B of the lower frame 12. The input unit 30 faces, apart from the upper side, of an opposing surface 12C of the lower frame 12 facing the upward side of the resin lower frame 12B.

[0021] The input section 30 includes an input unit 31 and a handle device 50. The input unit 31 includes a cover 32, a base 33, a cap 34, and a spiral gear 35.

[0022] The cover 32 covers the base 33, the cap 34, and the spiral gear 35 from the indoor side. By covering the base 33, the cap 34, and the spiral gear 35 from the indoor side with the cover 32, the design can be improved.

[0023] The base 33 has an end surface 33a facing the outdoors that is fixed to the surface of the resin lower frame 12B of the lower frame 12 facing the indoors from the indoor side. The base 33 has a cylindrical portion 33b and a recess 33f. The cylindrical portion 33b extends along a first axis J1 that extends upward from the outdoors toward the indoors. The cylindrical portion 33b has a first hollow portion 33c located on the lower side and a second hollow portion 33d located on the upper side. The first hollow portion 33c has a circular cross section. The spiral gear 35 is inserted from above into the first hollow portion 33c and is held rotatably about the first axis J1.

[0024] The second hollow portion 33d has a circular cross section. The diameter of the second hollow portion 33d is larger than the diameter of the first hollow portion 33c. The cylindrical portion 33b has an engagement hole 33e. The engagement hole 33e extends radially on both sides of the first axis J1. The engagement hole 33e communicates with the second hollow portion 33d on the radially inner side.

[0025] As shown in Fig. 5, the recess 33f is recessed from the end face 33a toward the indoor side. The recess 33f communicates with the first hollow portion 33c. A gear plate 41 (described later) is inserted into the recess 33f from the outdoor side. Since the recess 33f communicates with the first hollow portion 33c, the gear plate 41 inserted into the recess 33f can mesh with the spiral gear 35.

[0026] The cap 34 is inserted into the second cavity 33d from above, and the outer circumferential surface is held. The cap 34 has an engagement protrusion 34A. The engagement protrusion 34A is provided at a position facing the engagement hole 33e in the direction along the first axis J1. The engagement protrusion 34A is a snap fit. The engagement protrusion 34A elastically deforms radially inward when the cap 34 is inserted into the second cavity 33d. The engagement protrusion 34A elastically deforms radially inward and is inserted into the engagement hole 33e by an elastic restoring force when it faces the engagement hole 33e. The engagement protrusion 34A inserted into the engagement hole 33e engages with the cylindrical portion 33b from below, and the cap 34 is fixed to the base 33 in a state in which it is prevented from coming off. A spiral gear 35 is provided penetrating the cap 34.

[0027] 6, the spiral gear 35 extends along the first axis J1. The spiral gear 35 has worm teeth 35A, a knurled portion 35B, and a flange portion 35C. The spiral gear 35 corresponds to a rotating member.

[0028] The worm teeth 35A are provided on the outer periphery of the lower end side facing the outside. The worm teeth 35A are provided in a spiral shape centered on the first axis J1. When the spiral gear 35 is inserted into the cylindrical portion 33b of the base 33, the worm teeth 35A are held in the first cavity portion 33c.

[0029] As shown in Fig. 7, the handle device 50 has a connector 36 and a handle H. As shown in Fig. 8, the connector 36 has a base body 51, a deformable member 52, and a shaft portion 36C.

[0030] The base body 51 is formed of zinc die casting, for example. The base body 51 rotatably supports the handle H via the shaft portion 36C. The base body 51 has a fitting tube portion 36A, a fitting column portion 36B, a support shaft portion 36F, and a fitting recess 36G. The fitting tube portion 36A is cylindrical and extends along the first axis J1. A knurled portion 36D extending along the first axis J1 is provided inside the fitting tube portion 36A. As shown in FIG. 3, the upper side of the spiral gear 35 is inserted into the fitting tube portion 36A. When the upper side of the spiral gear 35 is inserted into the fitting tube portion 36A, the knurled portion 35B of the spiral gear 35 and the knurled portion 36D mesh with each other in the circumferential direction centered on the first axis J1. The knurled portion 35B and the knurled portion 36D mesh with each other in the circumferential direction, so that when the connector 36 rotates, the spiral gear 35 rotates.

[0031] The fitting column 36B is a square column extending along the first axis J1. The fitting column 36B is fitted with the handle H in the width direction along a third axis J3 that is perpendicular to the first axis J1 and runs along the indoor / outdoor direction. The fitting recess 36G is recessed downward from the surface facing upward in the fitting column 36B.

[0032] The support shaft portion 36F protrudes to the left side from the fitting column portion 36B. The support shaft portions 36F are provided in pairs spaced apart in the indoor / outdoor direction. A support hole 36H is formed in each of the support shaft portions 36F. The support holes 36H each pass through the support shaft portion 36F along the third axis J3. The shaft portion 36C is rotatably inserted into the support hole 36H.

[0033] The deformable member 52 is formed of a resin material such as polyacetal, for example. The deformable member 52 has a fitting column portion 52A and a fixed cylindrical portion 52B. The fitting column portion 52A has a rectangular column shape. The fitting column portion 52A is fitted from above into the fitting recess 36G of the fitting column portion 36B.

[0034] The fixed cylindrical portion 52B protrudes to the left from the fitting column portion 52A. The fixed cylindrical portion 52B is cylindrical and extends along the third axis J3. When the fitting column portion 52A is fitted into the fitting recess 36G, the fixed cylindrical portion 52B is inserted between the pair of support shaft portions 36F.

[0035] The fixed cylindrical portion 52B has an insertion hole 53, a second protrusion 54, and a hole 56. The insertion hole 53 passes through the fixed cylindrical portion 52B along the third axis J3. The shaft portion 36C is rotatably inserted into the insertion hole 53.

[0036] The deformable member 52 is integrated and fixed to the base 51 by fitting the fitting column portion 52A into the fitting recess 36G, inserting the fixed cylindrical portion 52B between a pair of support shaft portions 36F, and inserting the shaft portion 36C into the support hole 36H and the insertion hole 53.

[0037] The second protrusions 54 protrude radially outward from the outer circumferential surface of the fixed cylindrical portion 52B. The second protrusions 54 are arc-shaped and bulge radially outward. A plurality of second protrusions 54 are provided at intervals in the circumferential direction. Two second protrusions 54 are provided at intervals in the circumferential direction. The two second protrusions 54 are disposed at circumferential positions corresponding to the operating position and the storage position of the handle H, which will be described later.

[0038] The hole portion 56 is formed in the fixed cylindrical portion 52B in a direction along the third axis J3. In the handle device 50 of the embodiment, the hole portion 56 is a through hole 55 that penetrates the fixed cylindrical portion 52B. The hole portion 56 may be a recess that has a bottom and does not penetrate the fixed cylindrical portion 52B.

[0039] The through hole 55 is provided between the outer peripheral surface of the fixed cylindrical portion 52B and the insertion hole 53 in the radial direction. The through hole 55 is provided in a range in the circumferential direction where at least the second convex portion 54 is provided. The through hole 55 is arranged on the radially inner side of the second convex portion 54. By arranging the through hole 55 on the radially inner side of the second convex portion 54, the second convex portion 54 can easily elastically deform radially inward when a load is applied from the radially outer side.

[0040] The shaft portion 36C is shaped like a shaft having a circular cross section extending along the third axis J3. The shaft portion 36C is inserted into the support shaft portion 36F and the insertion hole 53 on the upper left side of the fitting column portion 36B. The insertion hole 53. The shaft portion 36C protrudes from the support shaft portion 36F on both sides in the direction along the third axis J3.

[0041] The handle H has an arm 37 and a knob portion 38. The handle H is formed mainly from a resin material such as polyamide, for example. The arm 37 extends in the left-right direction in a stored state, which will be described later. The arm 37 has a recess 37A, a hole portion 37B, and a first protrusion portion 37D.

[0042] The recess 37A is recessed from the lower side to the upper side of the arm 37. The recess 37A has a rectangular shape when viewed from below. The connector 36 is inserted into the recess 37A from the lower side. The arm 37 with the connector 36 inserted into the recess 37A from the lower side fits into the base body 51 in the width direction along the third axis J3.

[0043] The hole 37B penetrates the arm 37 in the direction along the third axis J3 via the recess 37A. The hole 37B has a circular shape when viewed from the third axis J3. When the connector 36 is inserted into the recess 37A from below, the arm 37 fits into the shaft 36C in the hole 37B.

[0044] Arm 37, which is fitted with shaft portion 36C in hole 37B, can rotate in the circumferential direction around shaft portion 36C. Arm 37 has a regulation wall 37C at the left end. When arm 37 rotates counterclockwise in FIG. 7 around shaft portion 36C, regulation wall 37C comes into contact with regulation surface 36E facing left in connector 36, thereby regulating the counterclockwise position of arm 37.

[0045] 9, the handle H has a first protrusion 37D. In the recess 37A, the first protrusion 37D protrudes radially inward at a position radially outward from the outer circumferential surface of the fixed cylindrical portion 52B of the deformation member 52, centered on the shaft portion 36C. The first protrusion 37D and the second protrusion 54 of the deformation member 52 overlap in the circumferential direction centered on the shaft portion 36C.

[0046] When the handle H rotates in the circumferential direction around the shaft portion 36C, the first convex portion 37D and the second convex portion 54 interfere with each other, increasing the load when the handle H is rotated, generating a clicking force. When the first convex portion 37D and the second convex portion 54 interfere with each other, the second convex portion 54 elastically deforms radially inward. As the second convex portion 54 elastically deforms radially inward, the first convex portion 37D climbs over the second convex portion 54. As the first convex portion 37D climbs over the second convex portion 54, the load when the handle H is rotated decreases. As the load when the handle H is rotated changes, a clicking sensation can be obtained.

[0047] In the recess 37A, the arm 37 that fits with the fitting column portion 36B in the width direction along the third axis J3 is rotatable in the circumferential direction about the first axis J1 together with the connector 36. By rotating the arm 37 in the circumferential direction about the first axis J1 by operation, the spiral gear 35 as a rotating member can be rotated via the connector 36. The handle H is rotatably connected to the spiral gear 35.

[0048] The knob 38 is a portion that the user grasps and operates when rotating the arm 37 in the circumferential direction about the shaft 36C and when rotating the arm 37 in the circumferential direction about the first axis J1. The knob 38 is detachably attached to the tip of the arm 37. The knob 38 is attached to the tip of the arm 37 that is rotatable about the shaft 36C. The knob 38 extends in a direction downward as it moves toward the right side relative to the arm 37 that extends in the left-right direction.

[0049] As shown in FIG. 10, the handle H is in a housed position along the inclined surface 32A of the cover 32 when the arm 37 is not rotating in the circumferential direction about the first axis J1 to rotate the spiral gear 35.

[0050] 11, when the arm 37 rotates counterclockwise about the first axis J1 to rotate the spiral gear 35, the handle H is in an operating position where the knob portion 38, which is defined by the defining wall 37C and the regulating surface 36E, faces upward along the first axis J1. The handle H can be folded from the operating position where the spiral gear 35 is rotated to a storage position where the spiral gear 35 is not rotated.

[0051] 12, when the handle H is in the stored position, the first convex portion 37D of the arm 37 is located on the opposite side in the circumferential direction to the second convex portion 54B located on the lower side relative to the second convex portion 54A located on the upper side of the second convex portion 54 of the deformation member 52. When the user rotates the handle H from the operating position to the stored position, the first convex portion 37D of the arm 37 interferes with the second convex portion 54A located on the upper side, and a clicking sensation can be obtained when the first convex portion 37D passes over the elastically deformed second convex portion 54A.

[0052] When the handle H in the stored position moves to the operating position, a click force is required due to interference between the first convex portion 37D of the arm 37 and the second convex portion 54A of the deformation member 52. If the handle H is not operated with a force exceeding the click force, the click force keeps the handle H in the stored position.

[0053] 13, when the handle H is in the operating position, the first convex portion 37D of the arm 37 is located on the opposite side in the circumferential direction from the upper second convex portion 54A relative to the lower second convex portion 54B of the second convex portion 54 of the deformation member 52. When the user rotates the handle H from the stored position to the operating position, the first convex portion 37D of the arm 37 interferes with the lower second convex portion 54B, and a clicking sensation can be obtained when the first convex portion 37D passes over the elastically deformed second convex portion 54B.

[0054] When the handle H in the operating position moves toward the storage position, a click force is required due to interference between the first convex portion 37D of the arm 37 and the second convex portion 54B of the deformation member 52. The handle H is held in the operating position by the click force unless it is operated with a force exceeding the click force.

[0055] It is preferable that the load when the first convex portion 37D gets over the second convex portion 54 differs among the multiple second convex portions 54. Making the load when the first convex portion 37D gets over the second convex portion 54 different can be realized, for example, by changing the protruding height of the second convex portion 54 or by making the size of the through hole 55 located on the radial inside of the second convex portion 54 different. By making the load when the first convex portion 37D gets over the second convex portion 54 different among the multiple second convex portions 54, the feeling of the clicking force obtained when the first convex portion 37D gets over the second convex portion 54 can be changed.

[0056] The output unit 40 outputs a driving force generated by the rotation of the spiral gear 35 to the opening and closing window 101. The output unit 40 has a gear plate 41, a connecting plate 42, and a bracket 43. The gear plate 41 is rotatably installed on the frame 1. The gear plate 41 has a gear plate 41A and a link plate 41B. The gear plate 41A is rotatable about the second axis J2. As shown in FIG. 5, the gear plate 41A is rotatably supported by a rotating shaft 33g extending along the second axis J2. The rotating shaft 33g is provided on the base 33.

[0057] 4 and 14, the gear plate 41A has teeth 41C on its outer periphery. The teeth 41C mesh with the worm teeth 35A of the spiral gear 35. A plurality of teeth 41C are provided at intervals in the circumferential direction. The teeth 41C are helical teeth whose tooth surfaces are inclined with respect to the second axis J2 in accordance with the inclination of the tooth tips of the worm teeth 35A with respect to the second axis J2.

[0058] The gear plate 41A rotates in response to the movement of the worm teeth 35A, which mesh with the tooth portion 41C, in a direction along the first axis J1 as the spiral gear 35 rotates. For example, when the spiral gear 35 rotates 360 degrees and the worm teeth 35A moves in a direction along the first axis J1, the gear plate 41A rotates by an amount corresponding to the pitch of the tooth portion 41C. The rotation direction of the gear plate 41A corresponds to the rotation direction of the spiral gear 35.

[0059] The link plate 41B curves and extends in a leftward direction from the gear plate 41A toward the outdoor side. The right end of the connecting plate 42 is rotatably connected to the link plate 41B about an axis extending in the vertical direction. The connecting plate 42 extends in a direction toward the indoor side as it approaches the left side. The left end of the connecting plate 42 is rotatably connected to the indoor end of the bracket 43 about an axis extending in the vertical direction. The bracket 43 is connected at its rear end to the lower frame 22 of the frame body 20 of the shoji screen 2 from the indoor side.

[0060] In the opening and closing device 3 and the fitting 100 of the embodiment, for example, by pinching the knob 38 and rotating the handle H, a driving force for opening and closing the opening and closing window 101 is input. For example, as shown in FIG. 15, the driving force generated when the handle H is rotated left rotates the gear plate 41A and the link plate 41B in a clockwise direction via the connector 36 and the spiral gear 35. When the gear plate 41A and the link plate 41B rotate in a clockwise direction, the connecting plate 42 and the bracket 43 move to the right, and the bracket 43 rotates in a counterclockwise direction. When the bracket 43 rotates in a counterclockwise direction, the driving force input by the rotation of the handle H is output, and the door tip of the door screen 2 opens toward the outside. When the door screen 2 is in an open state, the driving force generated when the handle H is rotated right can close the door screen 2 in the reverse operation to the above.

[0061] The operating position of the handle H is a position where the spiral gear 35 is rotated and the opening / closing window 101 is opened or closed via the output portion 40 as a predetermined operation.

[0062] In the handle device 50 and fitting 100 of the embodiment, a click force is generated by circumferential interference between the first convex portion 37D provided locally on the handle H and the second convex portion 54 provided locally on the deformable member 52, so there is no need to set the relative positional relationship between the handle H and the deformable member 52 with high precision, and it is possible to generate a click force with a simple configuration.

[0063] In the handle device 50 and the fitting 100 of the embodiment, multiple second convex portions 54 are provided to correspond to the operating position and the stored position of the handle H, so that the position of the handle H can be easily maintained in the operating position and the stored position.

[0064] In the handle device 50 and the fitting 100 of the embodiment, the handle H and the deformable member 52 are both formed containing a resin material, so that, for example, a situation in which the paint peels off from a decorative part with a protected paint treatment does not occur, as would occur if the handle H and the deformable member 52 were both formed from metal.

[0065] Although the preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings, it goes without saying that the present disclosure is not limited to the examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.

[0066] For example, in the embodiment, a configuration in which a plurality of second protrusions 54 are provided as either the first protrusions 37D or the second protrusions 54, and one first protrusion 37D as the other, is provided, is exemplified, but is not limited to this configuration. For example, a configuration in which one second protrusion 54 is provided and a plurality of first protrusions 37D are provided may also be used. Even in this configuration, it is preferable to arrange the first protrusions 37D at positions corresponding to the operation position and the storage position of the handle H, respectively.

[0067] In the embodiment, the opening / closing window 101 is a vertical sliding window whose door edge opens and closes around the vertical direction, but is not limited to this configuration.
