Description

Technical Field

[0001] The present invention relates to a switching device, for example, for switching the opening and closing of a closing body that closes a gap between a door and a lower frame of a frame body or a floor surface.

Background Art

[0002] Conventionally, a gap closing device is known that closes a gap generated between the lower end of a sliding door (opening / closing body) and the floor surface with a closing body when the sliding door is closed (see, for example, Patent Document 1).

[0003] In this gap closing device, when the sliding door is closed, the tip of the detection body abuts against the doorstop pillar, and the tip retreats into the cover of the detection body, thereby releasing the adsorption between the magnet of the closing body and the movable piece composed of the magnetic member of the detection body. The closing body hangs down toward the floor surface due to its own weight, closing the gap between the lower end of the sliding door and the floor surface.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the gap closing device described in Patent Document 1, when the tip of the detection body abuts against the doorstop pillar and the detection body retreats into the cover, the closing body always hangs down toward the floor surface due to its own weight and closes the gap. Therefore, when the sliding door is closed, the gap is always closed, and it is not possible to selectively operate between the case of closing the gap and the case of opening the gap.

[0006] The present invention has been made in view of the above points, and an object thereof is to provide a switching device with a simple configuration that can selectively operate to close or release a gap.

Means for Solving the Problems

[0007] In order to solve such problems, in the present invention, there is provided a switching device for a gap closing device that closes a gap between a door and a lower frame of a frame body or a floor surface by a gap closing device attached to a lower end portion of the door. The switching device includes a recess formed at a position corresponding to a shaft body of the gap closing device on a side surface of the vertical frame provided on a hanging end side of the door when the door is closed with respect to the vertical frame of the frame body, and a lid portion capable of selectively closing or opening the recess.

[0008] In the present invention, it is preferable that the recess has an inner diameter large enough to accommodate the shaft body.

[0009] In the present invention, it is preferable that the lid portion has a rotatable structure, and by rotating the lid portion, it is possible to selectively close or open the recess.

[0010] In the present invention, it is preferable that the lid portion has a slidable structure, and by sliding the lid portion, it is possible to selectively close or open the recess.

Advantages of the Invention

[0011] According to the above configuration, it is possible to realize a switching device with a simple configuration that selectively operates to close or release the gap.

Embodiments for Carrying Out the Invention

[0013] 1. Outline of the Embodiment First, an outline of a typical embodiment of the invention disclosed in the present application will be described. In the following description, as an example, reference numerals in the drawings corresponding to the components of the invention are described with parentheses.

[0014] 〔1〕In a typical embodiment of the present invention, a switching device (300) of a gap closing device (200) that closes a gap between a door (130) and a lower frame of a frame body or a floor surface by the gap closing device (200) attached to the lower end portion of the door (130), the concave portion (310) formed at a position corresponding to the shaft body (250) of the gap closing device (200) on the side surface (170a) of the vertical frame (170) provided on the suspension side of the door (130) when the door (130) is closed with respect to the vertical frame (170) of the frame body, and a lid portion (330) capable of selectively closing the concave portion (310) or releasing the concave portion (310).

[0015] 〔2〕In the present invention, the concave portion (310) has an inner diameter large enough to accommodate the shaft body (250).

[0016] 〔3〕In the present invention, the lid portion (330) has a rotatable structure, and by rotating the lid portion (330), it is possible to selectively close the concave portion (310) or release the concave portion (310).

[0017] 〔4〕In the present invention, the lid portion (430) has a slidable structure, and by sliding the lid portion (430), it is selected to close or release the recess (410).

[0018] 2. Specific Examples of Embodiments Hereinafter, with reference to FIGS. 1 to 6, the door device according to the embodiment of the present invention and the configuration of the switching device provided in the door device will be described in detail.

[0019] In the directions used in the following description, the door closing side where the door 130 closes in the door device 100 is defined as the rotation direction in which the door 130 closes toward the front side (arrow a direction) on the paper surface, and the door opening side where the door 130 opens is defined as the rotation direction in which the door 130 opens toward the back side (arrow b direction) on the paper surface. Therefore, the opening and closing direction is the arrow ab direction in which the door 130 draws an arc.

[0020] Also, the upper side is defined as the upper side (arrow c direction) when the door device 100 is viewed from the front, and the lower side is defined as the lower side (arrow d direction) when the door device 100 is viewed from the front. Therefore, the vertical direction or the gravitational direction is the arrow cd direction.

[0021] Furthermore, the left side is defined as the left side (arrow e direction) which is the hanging end side of the door 130 when the door device 100 is viewed from the front, and the right side is defined as the right side (arrow f direction) which is the door tip side of the door 130 when the door device 100 is viewed from the front. Therefore, the left - right direction or the horizontal direction is the arrow ef direction. However, the above - described opening and closing direction, vertical direction, and left - right direction are used for convenience of explanation, and can be defined as different directions depending on the usage situation where the door device 100 is placed.

[0022] <Door Device> As shown in FIGS. 1 and 2, in the embodiment of the present invention, the door device 100 is a hinged door, and includes a door 130, a gap closing device 200 provided at the lower end (in the direction of arrow d) of the door 130 (hereinafter referred to as the "lower end"), a vertical frame 170 of a frame body that supports the door 130 via a hinge 150 so as to be openable and closable, and a switching device 300 provided on the vertical frame 170.

[0023] Here, FIG. 1 shows, in the door device 100, the door closed state where the door 130 is closed with respect to the vertical frame 170 by a solid line, and the door open state where the door 130 is opened with respect to the vertical frame 170 by a dashed line. FIG. 2 shows, in the door device 100, the door open state where the door 130 is opened with respect to the vertical frame 170 by a solid line.

[0024] Incidentally, in the door device 100, it is composed only of the vertical frame 170 located on the left side (in the direction of arrow e) of the door 130, but it is not limited to this, and it may be composed of an upper frame, a lower frame, and left and right vertical frames like a frame body surrounding the four sides of the door 130. That is, any door device 100 in which there is a gap between the lower end of the door 130 and the floor surface or between the lower end of the door 130 and the lower frame may be used.

[0025] <Gap closing device> As shown in FIGS. 1 to 5, the gap closing device 200 is integrally attached to the lower end of the door 130 and has the same length as the width of the door 130 in the horizontal direction (in the direction of arrow ef).

[0026] The gap closing device 200 has a main body portion 210 integrally attached to the lower end of the door 130, a closing body 230 attached to the main body portion 210 and capable of opening and closing to close the gap with the floor surface, and a shaft body 250 for controlling the opening and closing of the closing body 230.

[0027] <Main body portion> The main body 210 of the gap closing device 200 is formed of a rectangular parallelepiped-shaped square tube member made of metal, resin, or the like, and is integrally fixed to the lower end portion of the door 130 by screws, adhesion, or the like. This main body 210 holds the shaft body 250 in a telescopic manner, and a closing body 230 is attached to the lower end portion of the main body 210 so as to be openable and closable.

[0028] <Closing body> The closing body 230 of the gap closing device 200 is a flap-shaped member made of, for example, resin or rubber having the same length as the width in the longitudinal direction of the main body 210. However, it is not limited to this, and the closing body 230 may be composed of various other materials such as a metal member or a sponge-like member.

[0029] When the tip of the shaft body 250 protrudes from the main body 210 by a predetermined length in the default state, an adsorption state is formed between the magnetic member of the shaft body 250 and the magnet of the closing body 230. Therefore, the closing body 230 sticks to the main body 210, and the gap between the door 130 and the floor surface cannot be closed, and it can be in a released state with a gap.

[0030] On the other hand, when the tip of the shaft body 250 is pushed and a state where it enters the inner space of the main body 210 is formed, the adsorption state between the magnetic member of the shaft body 250 and the magnet of the closing body 230 is released. Therefore, the closing body 230 hangs down from the main body 210 due to its own weight, and can be in a closed state that closes the gap.

[0031] <Shaft body> As shown in FIG. 3, the shaft body 250 of the gap closing device 200 is held in a telescopic manner with respect to the main body 210 in a default state where a portion other than the tip 250s is accommodated in the inner space of the main body 210 and the tip 250s protrudes from the main body 210 by a predetermined length.

[0032] The shaft body 250 is composed of a columnar or cylindrical member such as metal, and a magnetic member that is attracted to the magnet of the closing body 230 is attached to the portion housed in the inner space of the main body 210. Note that the shaft body 250 itself may be formed of a magnetic material such as metal, and in that case, it is not necessary to attach a magnetic member to the shaft body 250.

[0033] Also, in the default state, the tip 250s of the shaft body 250 protrudes from the main body 210 by a predetermined length. Further, the shaft body 250 is held in a stretchable state such that when the tip 250s is pushed to the right (in the direction of arrow f) along the longitudinal direction of the shaft body 250, it can enter the inner space of the main body 210.

[0034] Therefore, when the door 130 is closed with respect to the vertical frame 170, as the door 130 approaches the vertical frame 170, the tip 250s of the shaft body 250 approaches the lid portion 330 of the switching device 300 provided on the vertical frame 170.

[0035] Then, when the tip 250s of the shaft body 250 abuts against the lid portion 330 of the switching device 300, the tip 250s is pushed to the right (in the direction of arrow f) by the lid portion 330, so the tip 250s enters the inner space of the main body 210.

[0036] At this time, since the adsorption state between the magnetic member of the shaft body 250 and the magnet of the closing body 230 is released, the closing body 230 hangs down by its own weight from the main body 210, and the gap is closed by the closing body 230.

[0037] Note that a disc-shaped operation knob 255 having a larger outer diameter than the shaft body 250 is integrally provided at the tip of the tip 250s of the shaft body 250. In practice, when the tip 250s of the shaft body 250 abuts against the lid portion 330 of the switching device 300, the end face 255t of this operation knob 255 abuts against the lid portion 330.

[0038] The operation knob 255 is an operation part for changing the protruding amount of the distal end part 250s from the main body part 210, and for example, knurling is formed on its outer peripheral surface. The shaft body 250 has a threaded part, and is screwed into the threaded hole of the main body part 210. Therefore, when the user rotates the operation knob 255, the shaft body 250 protruding from the main body part 210 rotates, and the screwing position of the shaft body 250 screwed into the threaded hole of the main body part 210 is adjusted, so that the protruding amount of the distal end part 250s from the main body part 210 can be changed. This is because when the door 130 is closed, there is an error in the distance between the distal end part 250s of the shaft body 250 and the switching device 300 between the individual door devices 100, and it is necessary to absorb the error.

[0039] <Frame body> As shown in FIG. 3, the vertical frame 170 is composed of a columnar member having a rectangular parallelepiped shape, and a hinge 150 (FIGS. 1 and 2) for supporting the door 130 so as to be openable and closable is attached near the center in the vertical direction (arrow ab direction) of the side surface 170a facing the end surface 130a on the hanging side of the door 130.

[0040] Also, below the hinge 150 of the vertical frame 170 (in the direction of arrow d), a switching device 300 for controlling the opening and closing by the closing body 230 of the gap closing device 200 described later is provided.

[0041] <Switching device> The switching device 300 is provided so as to face the shaft body 250 at the lower end (in the direction of arrow d) of the side surface 170a of the vertical frame 170 facing the end surface 130a on the hanging side of the door 130, and has a recess 310 and a lid portion 330.

[0042] The recess 310 of the switching device 300 has a cylindrical concave space having an inner diameter larger than the outer diameter of the operation knob 255 on the shaft body 250 of the gap closing device 200, and is formed by fitting a cylindrical body 311 having a substantially hat-shaped cross section into a hole provided in the side surface 170a of the vertical frame 170. Note that the cylindrical body 311 of the recess 310 has a depth capable of completely accommodating the distal end part 250s of the shaft body 250 when the door 130 is completely closed.

[0043] In the cylindrical body 311 of the recess 310, a disk-shaped lid portion 330 for opening or closing the recess 310 is rotatably attached by a rotation shaft 331 at the upper end (in the direction of arrow c). The lid portion 330 has a size capable of closing the recess 310, and can maintain the recess 310 in an open state by the friction between the opening end portion 310a of the cylindrical body 311 and the side surface 170a of the vertical frame 170.

[0044] Therefore, when the user wants to close the gap between the door 130 and the floor surface by hanging down the closing body 230 of the gap closing device 200, the lid portion 330 is used to close the opening end portion 310a of the recess 310.

[0045] On the other hand, when the user does not want to close the gap between the door 130 and the floor surface by bringing the closing body 230 of the gap closing device 200 into close contact with the main body portion 210, the lid portion 330 is rotated to release the opening end portion 310a of the recess 310.

[0046] <Function and Effect> According to the above configuration, when the door device 100 wants to close the gap between the door 130 and the floor surface by the closing body 230 of the gap closing device 200, the lid portion 330 of the switching device 300 is rotated to close the opening end portion 310a of the recess 310.

[0047] As a result, when the door device 100 closes the door 130, the tip portion 250s of the shaft body 250 of the gap closing device 200 abuts against and is pushed by the lid portion 330 of the switching device 300, so that the closing body 230 hangs down and the gap can be closed by the closing body 230.

[0048] On the other hand, when the door device 100 does not want to close the gap between the door 130 and the floor surface by the closing body 230 of the gap closing device 200, the lid portion 330 of the switching device 300 is rotated to open the opening end portion 310a of the recess 310.

[0049] As a result, when closing the door device 100, the tip 250s of the shaft body 250 of the gap closing device 200 enters the inside of the recess 310 of the switching device 300, and the shaft body 250 is not pushed. Therefore, the closing body 230 does not hang down, and an open state can be formed in which the gap between the door 130 and the floor surface is not closed while leaving the gap.

[0050] In this way, since the switching device 300 of the door device 100 can control the opening and closing of the closing body 230, the closing or releasing of the gap between the door 130 and the floor surface can be selectively operated.

[0051] 3. Other Embodiments In the above-described embodiment, the case where the switching device 300 including the cylindrical recess 310 and the disc-shaped lid portion 330 is provided on the side surface 170a of the vertical frame 170 has been described. However, the present invention is not limited to this. As shown in FIG. 7, a switching device 400 including a recess 410 having a rectangular opening and a rectangular lid portion 430 may be provided on the side surface 170a of the vertical frame 170. Also in this case, the same effect as that of the switching device 300 can be obtained.

[0052] In the above-described embodiment, the case where the switching device 300 is provided below the hinge 150 of the vertical frame 170 (in the direction of arrow d) so that the gap between the door 130 and the floor surface is closed by the closing body 230 of the gap closing device 200 has been described. However, the present invention is not limited to this. The switching device 300 may be provided above the hinge 150 of the vertical frame 170 (in the direction of arrow c) so that the gap between the door 130 and the upper frame or the ceiling surface is closed by the closing body 230 of the gap closing device 200.

[0053] Furthermore, in the above-described embodiment, the case where the switching device 300 is provided in the door device 100 which is a hinged door has been described. However, the present invention is not limited to this, and the switching device 300 may be provided in a door device including a sliding door or a folding door.

[0054] In addition, those skilled in the art can appropriately modify the switching device of the present invention in accordance with conventionally known knowledge. As long as the configuration of the present invention is still provided by such modifications, of course, it is included in the scope of the present invention.
