  By the way, there is a handle in which a resin pedestal part is used for the pedestal for the purpose of maintaining the rotational position of the handle body. In such a case, when a fire occurs from one side of the door, the heat transmitted through the door may reach the pedestal part of the handle and the pedestal part may ignite.

  Conventionally, in order to prevent such a situation, the pedestal is made entirely of metal and resin pedestal parts are not used. However, when the pedestal is made entirely of metal, there is a problem that the cost becomes high.

  This invention is made | formed in view of this subject, The place made into the objective is to implement | achieve the opening part apparatus which can prevent ignition of a handle at low cost.

In order to achieve such an object, the opening device of the present invention is an opening device comprising a frame and a door provided on the frame and having a handle,
The handle is
A metal handle body,
It has a pedestal comprising a pedestal body for attaching the handle body to the door body and a resin pedestal part, and a melting point or a softening point is between the pedestal and the door body and the ignition point of the pedestal part. An opening device characterized in that a lower resin liner is provided.

  According to such an opening device, it is possible to prevent ignition of the handle at low cost.

Such an opening device,
The space in which the resin liner is located is preferably an air layer corresponding to the volume of the resin liner as the resin liner is melted or softened by the heat of flame.

  According to such an opening device, the resin liner is melted or softened by the heat of the flame, so that an air layer is formed between the door body and the base, and the air layer is formed by the presence of the air layer. The heat insulating effect is exerted so that the heat of the flame is hardly transmitted to the pedestal main body and the resin pedestal component, and the transmitted heat is easily radiated from the pedestal main body. Therefore, the temperature rise of the pedestal main body and the resin pedestal component exceeding the ignition point of the resin pedestal component can be suppressed. Therefore, it is possible to realize an opening device that can prevent ignition of the handle at low cost.

<<< About the structure of the handle 60 and its periphery >>>
Next, the structure of the handle 60 and its periphery according to the present embodiment will be described with reference to FIGS. FIG. 4 is an enlarged view of the handle 60 and its peripheral portion in FIG. FIG. 5 is a diagram showing the handle 60. FIG. 6 is an enlarged view in which the back surface of the base 64 is enlarged. FIG. 7 is a view showing the nut part 76. FIG. 8 is a view showing the resin liner 80. FIG. 9 is a view showing a state in which the pedestal 64 and the resin liner 80 are integrated (combined).

  The handle 60 is a portion that is provided so as to be rotatable with respect to the collar 56 and is operated by an operator to open and close the shoji 40. The handle 60 is provided on the indoor side surface of the flange 56.

  The handle 60 includes a handle main body 62, a pedestal 64, and a nut part 76.

  The handle main body 62 is a portion that can be gripped by an operator, and is normally in a state where the longitudinal direction thereof is along the vertical direction (see FIG. 1). When the operator rotates the handle body 62 by 90 degrees and shifts the longitudinal direction to the state along the left-right direction, the locking is released and the shoji 40 is opened. When the operator rotates the handle body 62 by 90 degrees and then pushes the shoji 40 in the expected direction (the direction from the indoor side toward the outdoor side) while holding the handle body 62, the shoji 40 is opened.

  The handle body 62 is made of metal and is rotatably attached to a pedestal 64 described later. That is, the handle main body 62 is provided with a shaft portion 62a whose axial direction is along the prospective direction, and the handle main body 62 rotates around the shaft portion 62a. The cross-sectional shape of the shaft portion 62a is a square shape.

  The pedestal 64 is for attaching the handle 60 (the handle body 62) to the flange 56. In the present embodiment, the pedestal 64 is attached to the flange 56 via a resin liner 80 described later. The pedestal 64 includes a metal part and a resin part, and has a rectangular shape in plan view. And it is attached to the collar 56 so that a long side direction follows an up-down direction.

  The pedestal 64 is configured by fitting a pedestal component 70 made of polyacetal resin (specific material is POM) into a metal pedestal main body 68. That is, a concave portion is formed on the back surface side of the pedestal main body 68 (that is, the surface side closer to the flange 56), and the pedestal component 70 is accommodated in the concave portion.

  A through hole through which the shaft portion 62 a passes is provided in the center portion of the base 64. Specifically, a circular main body through hole (not shown) is provided in the pedestal main body 68, and a circular component through hole 70a is provided in the pedestal component 70, respectively. It penetrates the component through hole 70a. Here, only the shaft portion 62a passes through the main body through hole, while both the nut portion 76 into which the shaft portion 62a and the shaft portion 62a are fitted pass through the component through hole 70a.

  That is, while the nut part 76 is a circular part, a square shaft through hole 76a for allowing the shaft part 62a to pass therethrough is provided at the center. Since the square shaft portion 62a passes through the square shaft through hole 76a, when the shaft portion 62a rotates, the nut part 76 rotates integrally with the shaft portion 62a. The material of the nut part 76 is made of a polyacetal-based resin (specific material is POM), like the base part 70.

  The nut part 76 includes a circular small diameter portion 77 and a large diameter portion 78 (the shaft portion 62a penetrates both the small diameter portion 77 and the large diameter portion 78). The small diameter portion 77 is provided closer to the flange 56 in the prospective direction than the large diameter portion 78. The small diameter portion 77 enters the component through hole 70a (through the component through hole 70a), while the large diameter portion 78 engages with a pair of spring members 72 provided on the base component 70. It is like that.

  That is, the outer peripheral portion of the large diameter portion 78 is provided with the concave portions 78a at four positions at intervals of 90 degrees. On the other hand, the spring member 72 is provided at two positions with an interval of 180 degrees, and the tip protrusion 72a of each spring member 72 has two recesses 78a facing each other out of the four recesses 78a (separate from each other by 180 degrees). The two recesses 78a) can be fitted simultaneously. In the state of FIG. 1 in which the longitudinal direction of the handle main body 62 is in the vertical direction, each tip convex portion 72a is fitted into two concave portions 78a facing each other out of the four concave portions 78a. From the state, when the operator rotates the handle body 62 by 90 degrees to shift the longitudinal direction to the state along the left-right direction, each of the tip protrusions 72a has the other two of the four recesses 78a. Thus, the spring member 72 of the pedestal part 70 is engaged with the nut part 76 that rotates integrally with the shaft part 62a of the handle body 62, and the handle body 62 is moved to 90. It plays the role of positioning every degree.

  Further, two screw holes are provided at both ends of the pedestal 64 in the long side direction. Specifically, a main body screw hole (not shown) is provided in the pedestal main body 68, and a component screw hole 70b is provided in the pedestal component 70. The screws (not shown) are the main body screw hole and the component screw hole 70b. It penetrates. The pedestal component 70 is provided with a circular protrusion 70c for fitting a resin liner 80 described later into the pedestal component 70, and a component screw hole 70b is disposed in the protrusion 70c. Caps 69 for concealing screws are provided at both ends of the pedestal 64 so as to cover the heads of the screws.

  The resin liner 80 is a resin-made member (specific material is styrene resin such as ASA) provided between the base 64 of the handle 60 and the collar 56 of the shoji 40. The melting point or softening point of the resin liner 80 (styrene resin such as ASA) is lower than the ignition point of the pedestal component 70 (polyacetal system such as POM) described above. Plays a role in preventing ignition of the base component 70 provided on the base 64 of the handle 60 (details will be described later).

  The resin liner 80 has a thickness and has a rectangular shape in plan view, like the pedestal 64. The resin liner 80 is in contact with both the flange 56 and the pedestal 64 while being sandwiched between the flange 56 and the pedestal 64 in the prospective direction (the pedestal 64 is in contact with the back surface of the pedestal 64. Therefore, the base part 70 is in contact with many parts). In the present embodiment, the outer surface 80 a of the resin liner 80 is flush with the outer surface 64 a of the pedestal 64.

  A liner through hole 80b through which the shaft portion 62a passes is provided at the center of the resin liner 80, and the shaft portion 62a through the through hole of the base 64 also penetrates the liner through hole 80b. The shaft portion 62a that penetrates the through hole of the base 64 and the liner through hole 80b reaches the flange 56, and is connected to a locking mechanism (not shown) provided on the flange 56.

  Also, two liner screw holes 80c are provided at both ends in the long side direction of the resin liner 80, and a screw (not shown) that penetrates the screw hole of the base 64 also penetrates the liner screw hole 80c. ing. The screw passing through the screw hole of the pedestal 64 and the liner screw hole 80c reaches the flange 56, whereby the pedestal 64 is fixed to the flange 56 via the resin liner 80.

=== Effectiveness of Vertical Sliding Window 10 According to the Present Embodiment ===
As described above, the vertical sliding window 10 according to the present embodiment includes the frame body 20 and the shoji 40 provided on the frame body 20 and having the handle 60. The handle 60 includes a metal handle main body 62, a pedestal 64 including a pedestal main body 68 for attaching the handle main body 62 to the shoji 40, and a resin pedestal component 70. In the meantime, a resin liner 80 having a melting point or softening point lower than the ignition point of the base part 70 is provided. Therefore, it is possible to realize the vertical sliding window 10 that can prevent ignition of the handle 60 at low cost.

  If the pedestal 64 is attached to the ridge 56 so as to contact each other without providing the resin liner 80 between the pedestal 64 and the shoji 40 (障 56), the pedestal component 70 is made of resin. When a fire occurs, there is a possibility that the heat transmitted through the eaves 56 reaches the pedestal component 70 and the pedestal component 70 is ignited. That is, in the present embodiment, since the handle 60 is located on the indoor side, a situation may occur where the handle 60 (the pedestal component 70) is ignited indoors due to an outdoor fire.

  Conventionally, in order to prevent such a situation, the pedestal 64 is made entirely of metal so that the resin pedestal component 70 is not used. However, when the pedestal 64 is made entirely of metal, there is a problem that the cost becomes high.

  On the other hand, in the present embodiment, a resin liner 80 is provided between the base 64 of the handle 60 and the collar 56 of the shoji 40, and the resin liner 80 has a melting point or a softening point that is a base component 70. The member was lower than the ignition point. Therefore, when a fire occurs, the heat of the flame transmitted through the eaves 56 reaches the resin liner 80, but the melting point or softening point of the resin liner 80 is lower than the ignition point of the pedestal component 70. Before ignition, the resin liner 80 melts or softens and falls. The resin liner 80 is melted or softened by the heat of the flame and falls, so that the space in which the resin liner 80 is located becomes an air layer corresponding to the volume of the resin liner 80. In other words, a gap corresponding to the thickness of the resin liner 80 is generated between the base 64 (the base component 70) and the flange 56. Then, the presence of the air layer causes the air layer to exert a heat insulating action, making it difficult for the heat of the flame to be transmitted to the pedestal 64 (the pedestal component 70), and for the transmitted heat, the pedestal 64 (the pedestal component). 70). Therefore, the temperature rise of the base 64 (base part 70) exceeding the ignition point is suppressed. Therefore, it is possible to realize the vertical sliding window 10 that can prevent the base 64 of the handle 60 from firing at low cost.

  Further, in the present embodiment, the material of the pedestal component 70 is a polyacetal resin, and the material of the resin liner 80 is a styrene resin.

  Therefore, since the melting point or softening point of the styrene resin is lower than the ignition point of the polyacetal resin, an air layer is formed between the door body and the pedestal by reliably removing the resin liner first, and the styrene resin Since various combinations of polyacetal-based resins can be performed, an appropriate material can be selected according to the need for use, function, price, and the like.

  Further, in the present embodiment, the material of the pedestal component 70 is POM, and the material of the resin liner 80 is ASA.

Since the ignition point of POM is about 400 degrees and the softening point of ASA is about 120 to 130 degrees, the softening point of the resin liner can be surely made lower than the ignition point of the base part made of resin.
Also, since ASA has a low softening point and a high ignition point, it can reduce the flame risk of the liner itself. Furthermore, since ASA can be painted, it has a good design when the handle and liner are combined, and it is also resistant to weathering, so it does not easily deteriorate.
