Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the above-described handle, when the width of the opening for the handle of the vertical frame is larger than the recessed portion of the handle body, the engaging protrusion cannot be engaged with the back surface of the vertical frame, and thus it cannot be attached to the vertical frame. For this reason, as the handle, only types corresponding to the dimensions of the opening for the handle formed in the vertical frame have to be prepared, which causes problems such as an increase in the number of handling parts.

[0005] In view of the above circumstances, an object of the present invention is to provide a handle capable of reducing the number of handling parts.

Means for Solving the Problems

[0006] To achieve the above objective, the pull handle according to the present invention is a pull handle that is attached to a pull handle opening provided in an shaped material, and comprises a pull handle body having a recessed portion positioned in the pull handle opening from the surface side of the shaped material, and a flange portion extending outward from the peripheral edge of the opening of the recessed portion, wherein the outer peripheral portion of the recessed portion is provided with an elastic fin portion that extends in an inclined direction from the bottom side of the recessed portion toward the outer peripheral portion and gradually approaches the flange portion toward the outer peripheral portion, and a retaining portion that protrudes outward from the elastic fin portion toward the outer peripheral portion, and the pull handle body is attached to the shaped material with the retaining portion engaged with the back side of the shaped material. [Effects of the Invention]

[0007] According to the present invention, even when the width of the handle opening provided in the profile is larger than the handle body, the elastic fin portion can be appropriately elastically deformed to allow for a seamless fit into the handle opening. As a result, the same handle can be used for profiles with different dimensions for the handle openings, thereby reducing the number of parts to be handled. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] A preferred embodiment of the pull handle according to the present invention will be described in detail below with reference to the attached drawings. For convenience, the terms "depth direction" and "face direction" may be used in the following description. The depth direction is the direction along the depth of the joinery, as indicated by arrow A in the figure. The surface along the depth direction may be referred to as the depth surface. The face direction is the direction along the vertical direction perpendicular to the depth direction, in the case of a frame that extends horizontally, such as a bottom frame. In the case of a frame that extends vertically, such as a vertical frame, the face direction is the direction along the horizontal direction perpendicular to the depth direction. The surface along the face direction may be referred to as the face surface.

[0010] (Embodiment 1) Figure 1 shows a door and window fitting to which a pull handle is applied, which is Embodiment 1 of the present invention. The door and window fitting illustrated here is a sliding window comprising a frame 10 and two sashes 20 that are slidably arranged to the left and right on the interior and exterior sides of the frame 10, respectively. The frame 10 is constructed by assembling an upper frame 11, a lower frame 12, and left and right vertical frames 13 around the perimeter. The two sashes 20 each have a panel 24 such as glass installed inside an upper frame 21, a lower frame 22, and left and right vertical frames 23 that are assembled around the perimeter. The upper frame 11, lower frame 12, and vertical frames 13 that constitute the frame 10, and the upper frame 21, lower frame 22, and vertical frames 23 that constitute the sashes 20, are extruded profiles formed from metal such as aluminum alloy or resin, respectively. Each of the two shoji screens 20 has a handle 1 on the facing surface of the vertical frame (shaped material) 23 that is the door edge and faces the room.

[0011] The handle 1 is used for gripping when sliding the shoji 20. In the first embodiment, as shown in FIGS. 2 to 3, the handle 1 is configured by attaching a handle body 30, an attachment 40, an underliner 50, and an upper liner 60 to a handle opening 25 provided in the vertical frame 23. The handle opening 25 is a through-hole provided in a flat finding wall portion 23a facing the interior in the vertical frame 23, and is formed in a rectangular shape with dimensions along the vertical direction being larger than the dimensions along the horizontal direction. Hereinafter, the configurations of the handle body 30 and the attachment 40 will be described in detail. When explaining the directions of the handle body 30 and the attachment 40 hereinafter, the respective directions will be specified in the posture attached to the vertical frame 23.

[0012] The handle body 30 is formed of resin and has a recessed portion 31 and a flange portion 32 as shown in FIG. 4. The recessed portion 31 forms a concave shape that opens to the interior side by integrally molding a bottom plate portion (bottom) 31a, two end plate portions 31b, and two side plate portions 31c, and is configured to have a size that can be inserted into the handle opening 25. The bottom plate portion 31a forms a substantially rectangular flat plate shape with dimensions along the vertical direction being larger than the dimensions along the horizontal direction. Both the dimension along the vertical direction and the dimension along the horizontal direction of the bottom plate portion 31a are configured to be smaller than the handle opening 25. The end plate portions 31b extend from the edges extending left and right above and below the bottom plate portion 31a toward the interior side such that the mutual distance gradually increases. The side plate portions 31c extend from the side edges extending up and down on the left and right of the bottom plate portion 31a toward the interior side such that the mutual distance gradually increases. The inclination angle of the side plate portions 31c is set smaller than the inclination angle of the end plate portions 31b. The flange portion 32 forms a flat plate shape provided so as to extend vertically and horizontally from the opening peripheral edge portion on the interior side of the recessed portion 31 toward the outer peripheral side, and forms a substantially rectangular shape having a long side portion 32a and a short side portion 32b. In the illustrated flange portion 32, the extension dimension from the end plate portion 31b is configured to be larger than the extension dimension from the side plate portion 31c.

[0013] On the above-mentioned handle body 30, engaging protrusions 31d are provided on the surfaces located on the outer peripheral sides of the side plate portions 31c, and extended bottom plate portions 31e are provided at the upper and lower ends of the bottom plate portion 31a, respectively. The engaging protrusion 31d is a protruding portion that extends vertically along a position where a gap is secured between it and the flange portion 32. The protruding dimension gradually increases toward the indoor side, and it has an engaging surface 31f along the finding direction at the portion located on the indoor side. In the illustrated example, two engaging protrusions 31d with the same position from the flange portion 32 to the engaging surface 31f are provided on each of the side plate portions 31c. The extended bottom plate portion 31e extends vertically from the end of the bottom plate portion 31a toward the outer peripheral side, and each extended edge portion has an elastic auxiliary fin portion 31g. The elastic auxiliary fin portion 31g extends obliquely in a direction gradually approaching the flange portion 32 from the extended bottom plate portion 31e toward the outer peripheral side, that is, in a direction gradually becoming the indoor side toward the outer peripheral side. The extended edge portion of the elastic auxiliary fin portion 31g is located on the outdoor side of the flange portion 32 and on the outer peripheral side of the end plate portion 31b. As is clear from the figure, in the first embodiment, the handle body 30 is configured to have a symmetric shape with respect to a virtual vertical plane that divides it into left and right, and a symmetric shape with respect to a virtual horizontal plane that divides it into upper and lower.

[0014] The attachment 40 is formed of a metal such as stainless steel, and as shown in FIGS. and

[0014] , it has a substrate portion 41, a main body support portion 42, an elastic fin portion 43, a first elastic auxiliary fin portion 44, and a second elastic auxiliary fin portion 45. The substrate portion 41 has a substantially rectangular flat plate shape with the dimension along the vertical direction being larger than the dimension along the horizontal direction. The dimension of the substrate portion 41 along the horizontal direction is configured to be slightly larger than the bottom plate portion 31a of the handle body 30. The dimension of the substrate portion 41 along the vertical direction is slightly larger than the dimension from the extended edge of one extended bottom plate portion 31e provided on the bottom plate portion 31a to the extended edge of the other extended bottom plate portion 31e, and is configured to be smaller than the handle opening 25 provided on the vertical frame 23.

[0015] The main support portion 42 is a flat plate shape that extends from the side edges extending vertically on the left and right sides of the base plate portion 41 toward the interior side, so as to be substantially parallel to each other. In the illustrated example, the main support portion 42 is provided at two positions on both side edges of the base plate portion 41, spaced apart from each other. More specifically, when the pull handle body 30 is placed in the central part of the base plate portion 41, the main support portion 42 is provided in a position that can cover the engaging projection 31d of the side plate portion 31c. Each main support portion 42 is provided with an engaging receiving surface 42a. The engaging receiving surface 42a contacts the engaging surface 31f of the side plate portion 31c when the pull handle body 30 is placed in the central part of the base plate portion 41, thereby preventing the pull handle body 30 from moving away from the base plate portion 41. The engaging receiving surface 42a is formed by creating rectangular notches in each of the main support portions 42. As is clear from the figure, the extension dimension of the main body support portion 42 from the base plate portion 41 is set so that a gap is secured between it and the flange portion 32 when the engaging projection 31d of the pull handle body 30 is brought into contact with the engaging receiving surface 42a.

[0016] The elastic fin portions 43 are provided on the side edges of the base portion 41 in the areas between the main body support portions 42, and extend in a sloping manner toward the interior side toward the outer periphery. In other words, when the engaging projection 31d of the pull handle body 30 is brought into contact with the engaging receiving surface 42a (hereinafter referred to as when the pull handle body 30 is supported by the main body support portion 42), the elastic fin portions 43 extend in a sloping manner toward the outer periphery, toward the direction of gradually approaching the flange portion 32, within the range of the side edge on the long side of the flange portion 32. These elastic fin portions 43 are elastically deformable, and their distance from each other can be expanded or contracted. The maximum width of the left and right elastic fin portions 43 in an unloaded state, that is, the maximum dimension from the surface located outside one elastic fin portion 43 to the surface located outside the other elastic fin portion 43, is set to be larger than the dimension along the left and right sides of the pull handle opening 25 provided in the vertical frame 23. The extension dimension of the elastic fin portion 43 from the base portion 41 is approximately the same as that of the main body support portion 42. Each elastic fin portion 43 is provided with a flange fin portion 43a at its extended edge. The flange fin portions 43a extend in a direction away from each other from the extended edge of the elastic fin portion 43. The surfaces of the flange fin portions 43a facing the outside are approximately parallel to the base portion 41 and are located on the same plane.

[0017] Each elastic fin portion 43 is provided with a retaining portion 46. The retaining portion 46 is in the shape of an elastic piece, comprising a first retaining piece 46a and a second retaining piece 46b. The first retaining piece 46a extends from the extended edge of the elastic fin portion 43, gradually inclined toward the outer circumference. In other words, when the pull handle body 30 is supported by the main body support portion 42, the first retaining piece 46a extends from the extended edge of the elastic fin portion 43 toward the outer circumference, gradually moving away from the flange portion 32. The second retaining piece 46b extends from the extended edge of the first retaining piece 46a, gradually inclined toward the inner circumference, gradually moving toward the outer circumference. In other words, the second retaining piece 46b extends in a direction that gradually moves away from the flange portion 32 from the extended edge of the first retaining piece 46a toward the inner circumference when the pull handle body 30 is supported by the main body support portion 42. In the illustrated example, the retaining portion 46 is formed by cutting and bending the central portion in the width direction along the top and bottom of the elastic fin portion 43.

[0018] The first elastic auxiliary fin portion 44 extends from both the upper and lower ends of the base portion 41, gradually inclined toward the interior side toward the outer periphery. When the pull handle body 30 is supported by the main body support portion 42, the first elastic auxiliary fin portion 44 extends from the base portion 41 toward the outer periphery, gradually inclined toward the flange portion 32, within the range of the edge on the short side of the flange portion 32. The second elastic auxiliary fin portion 45 extends from the extended base portion 47, which extends vertically toward the outer periphery from both the upper and lower ends of the base portion 41, gradually inclined toward the interior side toward the outer periphery. When the pull handle body 30 is supported by the main body support portion 42, the second elastic auxiliary fin portion 45 extends from the extended base portion 47 toward the outer periphery, gradually inclined toward the flange portion 32. The extension dimension of the first elastic auxiliary fin portion 44 from the base portion 41 and the projection dimension of the second elastic auxiliary fin portion 45 from the extended base portion 47 are approximately equal to the extension dimension of the main body support portion 42. As is clear from the figure, when viewed from the interior side, the first elastic auxiliary fin portion 44 is provided on the left side and the second elastic auxiliary fin portion 45 is provided on the right side above the base portion 41. Conversely, below the base portion 41, the second elastic auxiliary fin portion 45 is provided on the left side and the first elastic auxiliary fin portion 44 is provided on the right side.

[0019] The underliner 50 and the upper liner 60 are flat plate-shaped members molded from resin, and as shown in Figures 3, 7, and 8, they have a rectangular shape with an outer dimension larger than the flange portion 32 of the handle body 30. In particular, in this embodiment 1, the underliner 50 and the upper liner 60, which have the same outer dimensions as each other, are used. The underliner 50 is installed on the visible surface of the vertical frame 23 facing the interior, and is configured to have approximately the same plate thickness as the flange fin portion 43a of the elastic fin portion 43. The underliner 50 is provided with a lower notch 51. The lower notch 51 allows the recessed portion 31 of the handle body 30 to be inserted, but prevents the flange portion 32 from being inserted. In the illustrated example, a lower cutout 51 is applied, which has a lower main cutout 51a formed to the same size as the handle opening 25, and a lower first wide section 51b and a lower second wide section 51c formed on the side edge along the longitudinal side of the lower main cutout 51a. The lower first wide section 51b is a wide section formed in the part corresponding to the main support section 42 when the underliner 50 is superimposed on the interior-facing surface of the vertical frame 23 with the attachment 40 attached to the handle opening 25, and the lower main cutout 51a is aligned with the handle opening 25. The dimensions of this lower first wide section 51b are set along the top, bottom, left, and right to prevent interference with the main support section 42. The lower second wide section 51c is a wide section formed in the portion corresponding to the flange fin section 43a when the underliner 50 is superimposed on the interior-facing surface of the vertical frame 23 with the attachment 40 mounted on the handle opening 25, and the lower main cutout section 51a is aligned with the handle opening 25. The dimensions of this lower second wide section 51c are made larger in width along the top, bottom, left, and right directions than the lower first wide section 51b to prevent interference with the flange fin section 43a. The upper liner 60 is arranged superimposed on the surface of the underliner 50. The thickness of the upper liner 60 is set to be approximately the same as the gap dimension that occurs between the flange fin section 43a and the flange section 32 when the handle body 30 is supported by the main support section 42. The upper liner 60 is provided with an upper cutout 61.The upper notch 61 allows the recessed portion 31 of the handle body 30 to be inserted, but prevents the flange portion 32 from being inserted, and has an upper main notch 61a and an upper wide portion 61b. The upper main notch 61a has the same size as the handle opening 25 and is positioned at the same location as the lower main notch 51a when the upper liner 60 is superimposed on the underliner 50. The upper wide portion 61b is formed on the side edge along the longitudinal side of the upper main notch 61a and is formed at the same location as the lower first wide portion 51b when the upper liner 60 is superimposed on the underliner 50, with dimensions identical to the lower first wide portion 51b.

[0020] With the handle 1 configured as described above, for example, if the attachment 40, underliner 50, and upper liner 60 are sequentially attached to the vertical frame 23, and the handle body 30 is supported by the main support portion 42 of the attachment 40, the handle 1 can be provided on the vertical frame 23.

[0021] In other words, when the attachment 40 is placed in the handle opening 25 of the vertical frame 23 and pressed toward the handle opening 25, the second retaining pieces 46b provided on both sides of the attachment 40 come into contact with the side edges of the handle opening 25. At this time, the contact state of the elastic auxiliary fins 31g provided on both ends of the handle body 30 and the first elastic auxiliary fins 44 and second elastic auxiliary fins 45 provided on both ends of the attachment 40 with the handle opening 25 is checked, and a measure is taken to select one of them. In other words, if the elastic auxiliary fins 31g come into contact with both ends of the handle opening 25, the first elastic auxiliary fins 44 and second elastic auxiliary fins 45 of the attachment 40 are deformed so that they do not come into contact with the visible wall portion 23a of the vertical frame 23. When the first elastic auxiliary fin portion 44 abuts against both ends of the handle opening 25, the second elastic auxiliary fin portion 45 is deformed so that it does not abut against the visible wall portion 23a of the vertical frame 23. In the illustrated example, the first elastic auxiliary fin portion 44 abuts against both ends of the handle opening 25.

[0022] When the attachment 40 is pressed from the state described above, the tilting action of the second retaining piece 46b causes the retaining portion 46 and the elastic fin portion 43 to elastically deform in a direction that brings them closer to each other, and the tilting action of the first elastic auxiliary fin portion 44 causes the first elastic auxiliary fin portion 44 to elastically deform in a direction that brings it closer to each other, making it possible to insert the attachment 40 into the pull handle opening 25.

[0023] As shown in Figure 8, when the attachment 40 is inserted into the pull handle opening 25, the second retaining piece 46b passes the visible wall portion 23a of the vertical frame 23, causing the retaining portion 46 and the elastic fin portion 43 to deform in a direction that separates them from each other due to the elastic restoring force. As a result, the tilting action of the first retaining piece 46a, which abuts against the edge of the pull handle opening 25, pulls the attachment 40 into the pull handle opening 25, causing the flange fin portion 43a to abut against the visible surface of the vertical frame 23, and the retaining portion 46 to engage with the back surface of the visible wall portion 23a. Similarly, at both ends of the attachment 40, as shown in Figure 9, the extended edges of the first elastic auxiliary fin portion 44 abut against the inner wall surface of the pull handle opening 25. In this state, both the elastic fin portion 43 and the first elastic auxiliary fin portion 44 are in an elastically deformed state. Therefore, the elastic restoring force of the elastic fin portion 43 and the elastic restoring force of the first elastic auxiliary fin portion 44 act on the visible wall portion 23a of the vertical frame 23, which makes it possible to attach the attachment 40 to the vertical frame 23 without creating a gap between the flange fin portion 43a and the visible surface of the vertical frame 23.

[0024] From the above state, when the lower notch 51 is aligned with the handle opening 25 and the underliner 50 is placed on the visible surface of the vertical frame 23, as shown in Figures 8 and 9, the flange fin portion 43a is housed in the lower second wide portion 51c, and the surface of the flange fin portion 43a is located on a plane that is almost identical to the surface of the underliner 50. Furthermore, even if the main body support portion 42 protrudes from the visible surface of the vertical frame 23, it is housed in the lower first wide portion 51b, so the extended edge of the main body support portion 42 does not come into contact with the underliner 50. Moreover, when the upper liner 60 is placed on top of the surface of the underliner 50, the area around the handle opening 25 on the visible surface of the vertical frame 23 becomes flat. From this state, by pushing the handle body 30 onto the main support portion 42 of the attachment 40 via the upper notch 61 of the upper liner 60 and the lower notch 51 of the under liner 50, it becomes possible to attach the handle body 30 to the vertical frame 23 without creating a gap between the flange portion 32 and the upper liner 60.

[0025] Here, according to the pull handle 1 described above, the elastic fin portion 43 of the attachment 40 is configured to be elastically deformable. Therefore, as shown in Figure 10(a), the same pull handle body 30 can be reliably attached to a vertical frame 23A having a pull handle opening 25A with a larger left-right dimension d1 compared to the left-right dimension d of the pull handle opening 25 described above, as shown in Figure 10(b), and to a vertical frame 23B having a pull handle opening 25B with a smaller left-right dimension d2 compared to the pull handle opening 25 of the vertical frame 23 described above, as shown in Figure 10(c).

[0026] Specifically, for vertical frame 23A having a handle opening 25A with a large dimension along the left and right sides, the elastic fin portions 43 elastically deform outwards, allowing the retaining portion 46 to engage with the back surface of the visible wall portion 23a, and the flange fin portion 43a to contact the visible surface of vertical frame 23A. On the other hand, for vertical frame 23B having a handle opening 25B with a small dimension along the left and right sides, the elastic fin portions 43 elastically deform inwards, allowing the retaining portion 46 to engage with the back surface of the visible wall portion 23a, and the flange fin portion 43a to contact the visible surface of vertical frame 23B. Therefore, for any of the vertical frames 23, 23A, and 23B, by pushing the handle body 30 into the main body support portion 42 of the attachment 40, the handle body 30 can be attached to the vertical frame 23, 23A, and 23B without creating a gap between the flange portion 32 and the upper liner 60.

[0027] Similarly, the elastic auxiliary fin portion 31g of the pull handle body 30 and the first elastic auxiliary fin portion 44 and the second elastic auxiliary fin portion 45 of the attachment 40 are configured to be elastically deformable. Therefore, the pull handle body 30 can be reliably attached to vertical frames that have pull handle openings with different dimensions vertically than the pull handle opening 25 of the vertical frame 23 described above. In particular, in this embodiment 1, three types of elastic auxiliary fin portions 31g, 44, and 45 are provided at positions with different dimensions from each other, so by appropriately selecting these, it is possible to accommodate pull handle openings with larger differences in dimensions.

[0028] As explained above, with the handle 1 described above, the same handle body 30 and attachment 40 can be applied to vertical frames 23, 23A, and 23B whose handle openings 25, 25A, and 25B have different dimensions, making it possible to reduce the number of parts to handle and thus reduce manufacturing costs. Furthermore, even if there are molding or processing errors in the handle openings 25 configured to the same dimensions, the handle body 30 can be attached to the vertical frame 23 without causing looseness.

[0029] In the above-described embodiment 1, the attachment 40, underliner 50, and upper liner 60 are sequentially attached to the vertical frame 23, and the pull handle body 30 is supported by the main support portion 42 of the attachment 40. However, the pull handle body 30, attachment 40, and upper liner 60 may be pre-assembled and attached to the vertical frame 23. Furthermore, although the elastic fin portion 43 is provided on the attachment 40, which is separate from the pull handle body 30, it is also possible to mold the pull handle body 30 and the elastic fin portion 43 as a single unit, as shown in embodiment 2 below.

[0030] (Embodiment 2) Figures 11 and 12 show a handle according to Embodiment 2 of the present invention. The handle 1 illustrated here is attached to the handle opening 25 of the vertical frame 23 that forms the door edge of the sliding window sash 20, similar to Embodiment 1, but differs from Embodiment 1 in that the handle body configuration and attachment 40 are omitted. The following will mainly describe the differences from Embodiment 1, and components similar to those in Embodiment 1 will be given the same reference numerals and their detailed descriptions will be omitted. As with Embodiment 1, the orientation of the handle body when describing it will be determined by the orientation in which it is attached to the vertical frame 23.

[0031] The pull handle body 130 of Embodiment 2 has a recessed portion 31 and a flange portion 32 molded from resin. The recessed portion 31 and the flange portion 32 have the same configuration as in Embodiment 1. However, in Embodiment 2, the recessed portion 31 does not have an engaging projection 31d on the side plate portion 31c, but instead has elastic fin portions 133 on both side edges of the bottom plate portion 31a.

[0032] The elastic fin portions 133 are provided on the side edges of the bottom plate portion 31a at approximately the midpoint in the longitudinal direction, and extend in a direction that gradually approaches the flange portion 32 toward the outer circumference. These elastic fin portions 133 are elastically deformable and their spacing can be expanded or contracted. In the unloaded state, the maximum distance from the outer surface of one elastic fin portion 133 to the outer surface of the other elastic fin portion 133 is set to be greater than the distance along the left and right sides of the handle opening 25 provided on the vertical frame 23. Each elastic fin portion 133 is provided with a flange fin portion 133a at its extended edge. The flange fin portion 133a extends in a direction that separates it from the extended edge of the elastic fin portion 133. The surfaces of the flange fin portion 133a facing the outside are approximately parallel to the bottom plate portion 31a and are located on the same plane. The extension dimension of the elastic fin portion 133 from the bottom plate portion 31a is set to ensure a gap between the flange fin portion 133a and the flange portion 32.

[0033] Each elastic fin portion 133 is provided with a retaining portion 134. The retaining portion 134 is composed of a first retaining piece 134a and a second retaining piece 134b. The first retaining piece 134a extends from the extended edge of the elastic fin portion 133 toward the outer circumference, gradually moving away from the flange portion 32. The second retaining piece 134b extends from the extended edge of the first retaining piece 134a toward the inner circumference, gradually moving away from the flange portion 32.

[0034] The handle body 130 described above is provided with a first extended bottom plate portion 135a and a second extended bottom plate portion 135b at the upper and lower ends of the bottom plate portion 31a, respectively. The first extended bottom plate portion 135a and the second extended bottom plate portion 135b extend vertically from the end of the bottom plate portion 31a toward the outer circumference, and are formed to have different extension dimensions from each other. As is clear from the figure, when viewed from the indoor side, above the bottom plate portion 31a, the first extended bottom plate portion 135a with a smaller extension dimension is provided on the left side, and the second extended bottom plate portion 135b with a larger extension dimension is provided on the right side. Conversely, below the bottom plate portion 31a, the first extended bottom plate portion 135a is provided on the right side, and the second extended bottom plate portion 135b is provided on the left side. A first elastic auxiliary fin portion 136a is provided on the extended edge of the first extended base plate portion 135a, and a second elastic auxiliary fin portion 136b is provided on the extended edge of the second extended base plate portion 135b. The first elastic auxiliary fin portion 136a extends inclined from the first extended base plate portion 135a toward the outer circumference, gradually approaching the flange portion 32. The second elastic auxiliary fin portion 136b extends inclined from the second extended base plate portion 135b toward the outer circumference, gradually approaching the flange portion 32. The inclination angles of the first elastic auxiliary fin portion 136a and the second elastic auxiliary fin portion 136b are approximately equal to each other. The extended edges of the first elastic auxiliary fin portion 136a and the extended edges of the second elastic auxiliary fin portion 136b are located on the outside of the flange portion 32 and on the outer circumference of the end plate portion 31b. As is clear from the figure, in this embodiment 2, the handle body 130 is configured to be symmetrical with respect to a virtual vertical plane that divides the space left and right, and symmetrical with respect to a virtual horizontal plane that divides the space up and down.

[0035] With the handle 1 configured as described above, if the underliner 50 and upper liner 60 are attached to the vertical frame 23, and the handle body 130 is attached to the handle opening 25, the handle 1 can be installed on the vertical frame 23.

[0036] In other words, the handle body 130 is placed in the handle opening 25 of the vertical frame 23 fitted with the underliner 50 and upper liner 60. When the handle body 130 is pressed toward the handle opening 25 from this position, the second retaining pieces 134b provided on both sides of the handle body 130 come into contact with the side edges of the handle opening 25. At this time, the contact state between the first elastic auxiliary fin portion 136a and the second elastic auxiliary fin portion 136b provided at both ends of the handle body 130 and the handle opening 25 is checked, and a measure such as cutting is taken to select one of them. In other words, if the first elastic auxiliary fin portion 136a comes into contact with both ends of the handle opening 25, the second elastic auxiliary fin portion 136b is cut off so that it does not come into contact with the visible wall portion 23a of the vertical frame 23. When the second elastic auxiliary fin portion 136b abuts against both ends of the pull handle opening 25, the first elastic auxiliary fin portion 136a is left as is. In the illustrated example, the explanation is given assuming that the second elastic auxiliary fin portion 136b abuts against both ends of the pull handle opening 25.

[0037] When the pull handle body 130 is pressed from the state described above, the tilting action of the second retaining piece 134b causes the retaining portion 134 and the elastic fin portion 133 to elastically deform in a direction that brings them closer to each other, and the tilting action of the second elastic auxiliary fin portion 136b causes the second elastic auxiliary fin portion 136b to elastically deform in a direction that brings it closer to each other, making it possible to insert the pull handle body 130 into the pull handle opening 25.

[0038] As shown in Figure 15, when the pull handle body 130 is inserted into the pull handle opening 25, the retaining portion 134 and the elastic fin portion 133 deform in a direction that separates them from each other due to the elastic restoring force when the second retaining piece 134b passes the visible wall portion 23a of the vertical frame 23. As a result, the tilting action of the first retaining piece 134a, which abuts against the edge of the pull handle opening 25, pulls the pull handle body 130 into the pull handle opening 25, causing the flange fin portion 133a to abut against the visible surface of the vertical frame 23, and the retaining portion 134 to engage with the back surface of the visible wall portion 23a. Similarly, at both ends of the pull handle body 130, as shown in Figure 16, the extended edges of the second elastic auxiliary fin portion 136b abut against the inner wall surface of the pull handle opening 25. In this state, both the elastic fin portion 133 and the second elastic auxiliary fin portion 136b are in an elastically deformed state. Therefore, the elastic restoring force of the elastic fin portion 133 and the second elastic auxiliary fin portion 136b acts on the visible wall portion 23a of the vertical frame 23, which makes it possible to attach the handle body 130 to the vertical frame 23 without creating a gap between the flange fin portion 133a and the visible surface of the vertical frame 23.

[0039] Here, according to the pull handle 1 described above, the elastic fin portion 133 of the pull handle body 130 is configured to be elastically deformable. Therefore, as shown in Figure 17(a), the same pull handle body 130 can be reliably attached to a vertical frame 23A having a pull handle opening 25A with a larger left-right dimension d1 compared to the left-right dimension d of the pull handle opening 25 described above, as shown in Figure 17(b), and to a vertical frame 23B having a pull handle opening 25B with a smaller left-right dimension d2 compared to the pull handle opening 25 of the vertical frame 23 described above, as shown in Figure 17(c).

[0040] Specifically, for a vertical frame 23A having a handle opening 25A with a large dimension along the left and right sides, the elastic fin portions 133 elastically deform outwards, allowing the retaining portion 134 to engage with the back surface of the visible wall portion 23a, and the flange fin portion 133a to contact the visible surface of the vertical frame 23A. On the other hand, for a vertical frame 23B having a handle opening 25B with a small dimension along the left and right sides, the elastic fin portions 133 elastically deform inwards, allowing the retaining portion 134 to engage with the back surface of the visible wall portion 23a, and the flange fin portion 133a to contact the visible surface of the vertical frame 23B. Therefore, by pushing the handle body 130 into the handle opening 25, 25A, 25B for any of the vertical frames 23, 23A, 23B, it becomes possible to attach the handle body 130 to the vertical frames 23, 23A, 23B without creating a gap between the flange portion 32 and the upper liner 60.

[0041] Similarly, the first elastic auxiliary fin portion 136a and the second elastic auxiliary fin portion 136b of the pull handle body 130 are configured to be elastically deformable. Therefore, the pull handle body 130 can be reliably attached to vertical frames that have pull handle openings with different dimensions vertically relative to the pull handle opening 25 of the vertical frame 23 described above. In particular, since two types of elastic auxiliary fin portions 135a and 135b are provided at positions with different dimensions from each other, it is possible to accommodate pull handle openings with even larger differences in dimensions by selecting between them.

[0042] Thus, with the handle 1 described above, the same handle body 130 can be applied to vertical frames 23 whose handle openings 25 have different dimensions, making it possible to reduce the number of parts to be handled and thus reduce manufacturing costs. Furthermore, even if there are molding or processing errors in the handle openings 25 configured to the same dimensions, the handle body 130 can be attached to the vertical frame 23 without causing looseness.

[0043] In the above-described embodiment, a handle 1 attached to the vertical frame 23 that forms the door edge of a sliding window is illustrated. However, the present invention is not limited to this, and may be applied to the vertical frame 23 that forms the door edge of a single-sliding window, or to the upper frame 21 or lower frame 22 that forms the door edge of a double-hung window. In this case, the profile does not necessarily have to be hollow. Also, while the handle body 130 is illustrated as a large rectangle along the length of the profile, it is not necessarily limited to this, and may be other shapes such as squares, ovals, circles, etc. Furthermore, in the rectangular shape of the handle body 130, elastic auxiliary fins 31g are provided at both the upper and lower edges, but it is not necessary to provide the elastic auxiliary fins 31g. Moreover, in Embodiment 2, elastic fins 133 are provided on the bottom plate portion 31a of the handle body 130, but they can also be provided on the side plate portion 31c. Furthermore, while the retaining portion 134 is exemplified as an elastic piece extending from the elastic fin portion 133 toward the outer circumference, gradually moving away from the flange portion 32, it is not necessarily limited to this, and any protruding part that extends from the elastic fin portion 133 may be a projection. In addition, although the elastic fin portion 133 is provided to engage with each of the opposing opening edges of the pull handle opening 25, the elastic fin portion 133 may be provided to engage with only one opening edge of the pull handle opening 25. Also, although the underliner 50 and upper liner 60 are configured as separate parts, these underliner and upper liner may be configured as a single part, or the underliner and upper liner may be molded integrally with the pull handle body.

[0044] As described above, the pull handle according to the present invention is a pull handle that is attached to a pull handle opening provided in an shaped material, and comprises a pull handle body having a recessed portion positioned in the pull handle opening from the surface side of the shaped material, and a flange portion extending outward from the peripheral edge of the opening of the recessed portion, wherein the outer peripheral portion of the recessed portion is provided with an elastic fin portion that extends in an inclined direction from the bottom side of the recessed portion toward the outer peripheral portion and gradually approaches the flange portion toward the outer peripheral portion, and a retaining portion that protrudes outward from the elastic fin portion toward the outer peripheral portion, and the pull handle body is attached to the shaped material with the retaining portion engaged with the back side of the shaped material. According to this invention, even when the width of the handle opening provided in the profile is larger than the handle body, the elastic fin portion can be appropriately elastically deformed to allow the handle to be fitted into the opening without any gaps. As a result, the same handle can be used for profiles with different dimensions of handle openings, thereby reducing the number of parts to be handled.

[0045] Furthermore, the present invention is characterized in that, in the pull handle described above, the retaining portion is configured as an elastic piece that extends in an inclined direction from the elastic fin portion toward the outer circumference, gradually moving away from the flange portion. According to this invention, when attached to an shaped material, the elastic retaining piece biases the elastic engaging piece toward the back surface relative to the shaped material, thus preventing gaps from forming between the elastic engaging piece and shaped materials of different thicknesses.

[0046] Furthermore, the present invention is characterized in that, in the pull handle described above, the extended edge of the retaining portion extends in a direction that gradually moves away from the flange portion toward the inner circumference. According to this invention, the retaining portion of the elastic tongue can be easily inserted into the opening for the pull tab.

[0047] Furthermore, the present invention is characterized in that, in the pull handle described above, the elastic fin portion is provided with a flange fin portion that extends along the surface of the profile at its extended edge, and the opening edge portion of the profile is positioned between the flange fin portion and the retaining portion. According to this invention, the elastic fin portion can be attached to the profile while the flange fin portion is in contact with the surface of the profile.

[0048] Furthermore, the present invention is characterized in that, in the pull handle described above, the flange portion has two long sides and a short side connecting the ends of the long sides, and the elastic fin portion is provided in a position that is within the range of the two long sides on the outer circumference side of the recess. According to this invention, even if there is a gap between the handle opening and the handle body in the range of the long side of the flange portion, the elastic fin portion will appropriately deform elastically, making it possible to attach the handle to the handle opening without any gaps.

[0049] Furthermore, the present invention is characterized in that, in the pull handle described above, an elastic auxiliary fin portion is provided at a position corresponding to the short side portion on the outer circumferential side of the recess, which is located at the bottom of the recess and gradually slopes toward the flange portion toward the outer circumferential side, with the extended edge portion in contact with the inner wall surface of the pull handle opening. According to this invention, even if there is a gap between the handle opening and the handle body along the short side direction of the flange portion, the elastic auxiliary fin portion can be appropriately elastically deformed to allow the handle to be attached to the handle opening without any gaps.

[0050] Furthermore, the present invention is characterized in that, in the pull handle described above, a plurality of elastic auxiliary fin portions are provided, each having a different distance from the short side portion to the extended edge portion. According to this invention, by selecting the elastic auxiliary fin portion, the range of dimensions that can accommodate the gap between the handle opening and the handle body along the short side direction of the flange portion is increased.

[0051] Furthermore, the present invention is characterized in that, in the pull handle described above, the elastic fin portion is configured as an attachment separate from the pull handle body, and the attachment is provided with a body support portion that supports the pull handle body. According to this invention, the pull handle body and the elastic fin portion can be molded from different materials.

[0052] Furthermore, the present invention is characterized in that, in the pull handle described above, the elastic fin portion is molded integrally with the pull handle body. This invention makes it possible to further reduce the number of parts that need to be handled. [Explanation of Symbols]
