Description

Plane materiel opener and door and window

Technical Field

The invention relates to a plane material opener and a door and window.

Background

Some doors and windows, such as sliding doors, having a surface member disposed so as to be movable along a lateral frame of a housing, include a surface member opener. In general, a door or window such as a sliding door is provided with a handle on a surface of a front end side of a surface material, and the surface material can be opened by operating the handle. The plane material opener is a structure configured to open the plane material without touching the handle. Such a face material opener is described in patent document 1, for example. The surface material opener is provided with a pressing member and a link mechanism on a vertical frame, and when the link mechanism is operated by an operation input unit, the pressing member presses an end surface on a tip side of a surface material to open the surface material.

Patent document 1: japanese patent laid-open No. 2020 and 84404

Disclosure of Invention

However, in the above-described face material opener, in order to close the face material without generating a gap between the face material and the vertical frame, the pressing member and a part of the link mechanism for operating the pressing member must be accommodated in the vertical frame. Therefore, when the existing door window is additionally installed, a complicated operation is required. In order to solve such a problem, it is conceivable to add a new vertical frame incorporating a face material opener to the original vertical frame. However, in the door/window to which the new vertical frame is added, not only the opening area when the face material is opened is reduced, but also an operation of matching the size of the new vertical frame with the size between the upper frame and the lower frame is required.

In view of the above circumstances, an object of the present invention is to provide a surface material opener and a door window that can be easily installed without reducing the opening area of the door window.

In order to achieve the above object, a surface material opener according to the present invention is a door/window surface material opener including a frame body and a surface material, the frame body having a horizontal frame and a vertical frame; the surface material opener is disposed so as to be movable in the extending direction of the lateral frame, and includes: a receiving member provided on the surface material in a state of protruding from at least one side surface of the surface material; a pressing member disposed at a position facing the receiving member; and a link mechanism having one end connected to the pressing member and an operation input portion at the other end, the link mechanism moving relative to the vertical frame when the operation input portion is operated to press the pressing member.

According to the present invention, since the receiving member is provided on the surface of the surface material and the pressing member presses the receiving member, airtightness between the depth surface of the surface material and the depth surface of the vertical frame can be ensured without accommodating the pressing member in the vertical frame. Further, the pressing member or the link mechanism does not need to be provided between the upper frame and the lower frame without a gap. As a result, it is not necessary to perform troublesome work when additionally installing the existing door/window, and it is possible to avoid a situation where the opening area is greatly reduced when opening the surface material.

Detailed Description

Hereinafter, preferred embodiments of the opening device for a surface material and the door/window according to the present invention will be described in detail with reference to the accompanying drawings. For convenience, the following description will be made using terms such as "depth direction" and "front view direction". The depth direction is a direction along the depth direction of the door/window as indicated by an arrow a in the drawing. The surface along the depth direction may be referred to as a depth surface. The front view direction is a direction perpendicular to the depth direction in the vertical direction when the object extends in the horizontal direction, such as an upper frame or a lower frame described later. In the case of an object extending in the vertical direction, such as a vertical frame, the horizontal direction perpendicular to the depth direction is referred to as the main viewing plane direction. The surface along the main viewing surface direction may be referred to as a main viewing surface.

Fig. 1 is a view showing a door and window provided with a surface material opener according to an embodiment of the present invention. The door window illustrated here is a door window called a single sliding door provided at an opening of an indoor wall that separates a passage and a room, for example, and includes a frame 10 and a door body (surface material) 20.

The frame body 10 is formed in a rectangular frame shape by an upper frame (horizontal frame) 11, a lower frame (horizontal frame) 12, and left and right

vertical frames

13 and 14, and is formed by providing a middle vertical frame 15 along a portion on the room side between the upper frame 11 and the lower frame 12. Specifically, as shown in fig. 2, the dimension in the depth direction of the vertical frame (hereinafter referred to as the front end frame 13 when distinguished) located on the left side when viewed from the passage side is larger than the dimensions in the depth direction of the vertical frame (hereinafter referred to as the rear end frame 14 when distinguished) and the middle vertical frame 15 located on the right side when viewed from the passage side. As is apparent from the figure, the depth surface 13a of the front end frame 13 faces the depth surface 14a of the rear end frame 14 and the depth surface 15a of the center stile 15, and is substantially parallel to the depth surface 14a of the rear end frame 14 and the depth surface 15a of the center stile 15. The front surface 13b of the front end frame 13 located on the passage side is substantially flush with the front surface 14b of the rear end frame 14 and the front surface 12b of the lower frame 12. The front surface 13c of the front end frame 13 located on the room side is substantially flush with the front surface 15c of the center mullion 15 and the front surface 12c of the lower frame 12. An opening 1 opened or closed by a door 20 is formed between the front end frame 13 and the center stile 15. Between the end stiles 14 and the center stiles 15, they are closed by walls extending on the room side. The portion on the passage side between the center stile 15 and the rear end stile 14 forms a door housing space in which the door 20 is disposed when the opening 1 is opened.

Recesses

13d, 14d are provided in the mutually facing portions of the depth surface 13a of the front end frame 13 and the depth surface 14a of the rear end frame 14. The

recessed portions

13d, 14d are configured such that the width dimension in the depth direction is larger than the plate thickness of the door body 20, and are provided along the entire length of each of the front end frame 13 and the rear end frame 14 in the longitudinal direction.

The door 20 is a flat plate-shaped member formed to have a size capable of closing the opening 1 between the front end frame 13 and the center stile 15. Although not shown in the drawings, the door 20 is slidably supported by the lower frame 12 via a door pulley provided at a lower end portion thereof, and is movable in an extending direction (arrow B in the drawings) of the lower frame 12 in a region where the recessed portion 13d of the front end frame 13 and the recessed portion 14d of the rear end frame 14 face each other. The thickness of the door body 20 is set smaller than the depth-direction dimension of the rear end frame 14. As is apparent from the figure, the door 20 is disposed at a position close to the center stile 15 in the depth direction of the frame 10, and the surface of the door 20 on the passage side (hereinafter, simply referred to as passage side surface 20a) is closer to the room side than the front view surface 13b of the front end frame 13 on the passage side. A handle 21 is attached to a passage-side surface 20a and a room-side surface (hereinafter, simply referred to as a room-side surface 20b) of the door 20 at a substantially central portion in the height direction of the front end side.

The door and window is provided with a plane material opener 30. The surface material opener 30 described in the present embodiment is a surface material opener for opening the door body 20 without touching the handle 21 when entering a room from the passage side, and includes a receiving member 31, a link (link mechanism) 32, and a pressing arm (pressing member) 33, as shown in fig. 3 to 8.

The receiving member 31 is attached to a portion of the passage-side surface 20a of the door 20 below the handle 21, and includes a receiving body 31a and a cover 31 b. The receiving body 31a is a vertically long rectangular parallelepiped, and is fixed to a portion on the front end side of the door body 20 in a state where a receiving surface 31c, which is a side portion close to the front end frame 13, is substantially vertical in the depth direction. As is apparent from the drawing, the receiving surface 31c of the receiving body 31a is located closer to the rear end side than a depth surface located on the front end side of the door body 20 (hereinafter, referred to as a front end surface 20 c). The protruding end surface 31d of the receiving body 31a on the passage side is substantially flush with the front surface 13b of the front end frame 13 on the passage side. The cover portion 31b is formed in a thin plate shape protruding from the protruding end of the receiving body portion 31a toward the depth surface 13a of the front end frame 13, and extends substantially parallel to the passage-side surface 20a of the door 20 while ensuring a gap with the passage-side surface 20a of the door 20. The extension length of the hood 31b is set to: when the door 20 is closed, that is, when the front end surface 20c of the door 20 abuts against the depth surface 13a of the front end frame 13, the extension edge does not abut against the depth surface 13a of the front end frame 13.

As shown in fig. 3 and 4, the connecting rod 32 has an elongated flat plate shape, and has an arm connecting portion 32a at one end portion and a pedal coupling portion 32b at the other end portion. The arm connecting portion 32a is rotatably connected to a pressing arm 33 described later by a pivot shaft 34, and the pivot shaft 34 is parallel to the surface of the link lever 32 and orthogonal to the extending direction of the link lever 32. The pedal coupling portion 32b is coupled to a pedal (operation input portion) 36 via a coupling shaft 35, which will be described later, and is configured in an elongated hole shape in a direction orthogonal to the extending direction of the link 32, and the coupling shaft 35 extends so as to be orthogonal to both the surface of the link 32 and the extending direction of the link 32. And in the connecting rod 32, a slide guide hole 32c is provided between the arm connecting portion 32a and the pedal coupling portion 32 b. The slide guide holes 32c are slit-shaped holes extending in the longitudinal direction of the tie bar 32 at the center portion in the width direction of the tie bar 32, and two are provided in the longitudinal direction of the tie bar 32.

The link lever 32 is attached to the depth surface 13a of the front end frame 13 by screwing the attachment screw S to the front end frame 13 through the screw insertion hole 37a of the rail member 37 and the slide guide hole 32c with the arm connecting portion 32a positioned upward. The rail member 37 is a long member having a length shorter than that of the link 32, and includes a guide plate portion 37b and two support protrusions 37 c. The guide plate portion 37b is a flat plate member having a width slightly wider than the flat plate portion of the link lever 32. The two supporting protrusions 37c protrude in the same direction from the opposite side edges of the flat plate portion. The protruding dimension of the support protrusion 37c is set to be slightly larger than the plate thickness of the flat plate portion of the link 32. The rail member 37 is attached to the front end frame 13 in a state where the two supporting protrusions 37c contact the depth surface 13a of the front end frame 13, and supports the link 32 in a state where the link 32 is capable of moving in the vertical direction between the rail member 37 and the front end frame 13 and is prevented from moving in the left-right direction.

As is also apparent from fig. 2 (b), the position of the coupling rod 32 attached to the depth surface 13a of the front end frame 13 is closer to the passage side than the recess 13d and closer to the room side than the cover 31b of the receiving member 31. That is, in this door/window, the link 32 is disposed in a depth range facing the receiving surface 31c of the receiving member 31 in the depth surface 13a of the front end frame 13 so as to be vertically movable. The extended length of the link 32 and the extended length of the rail member 37 are set such that, as shown in fig. 3 (a), the pedal attachment portion 32b can substantially abut against the ground when the link 32 is disposed at the lowermost position, and as shown in fig. 3 (b), the arm attachment portion 32a is located below the receiving member 31 of the door body 20 when the link 32 is disposed at the uppermost position.

As shown in fig. 3 and 5, the pedal coupling portion 32b of the connecting rod 32 is coupled to the pedal 36. The pedal 36 is a rocker-type pedal operation input member, which is rotatably supported on a support base 39 via a support shaft 38 provided at a central portion in the longitudinal direction, and operates such that one end portion moves downward while the other end portion moves upward. One end portion (hereinafter, referred to as an action end portion 36a in a distinguished case) of the pedal 36 is provided with a coupling shaft 35. The coupling shaft 35 extends parallel to the support shaft 38, and its end projects outward from the side surface of the pedal 36. The pedal 36 is mounted on the floor via a support base 39 in a state in which a support shaft 38 extends substantially horizontally in the longitudinal direction of the lower frame 12 and an end of the coupling shaft 35 is coupled to the pedal coupling portion 32b of the coupling lever 32. In the figure, reference numeral 39a denotes a cover provided above the support base 39. The cover 39a is attached to the support base 39 so as to cover the operating end 36a of the pedal 36 and expose the opposite end (hereinafter referred to as the input end 36b in the case of distinction) to the outside.

As described above, the pedal 36 coupled to the link 32 via the coupling shaft 35 is in a state in which the working end 36a provided with the coupling shaft 35 is positioned below and the input end 36b is positioned above due to the weight of the link 32 and the weight of the pressing arm 33 described later. For example, when the input end 36b of the pedal 36 is depressed and moved downward from the above state, the action end 36a of the pedal 36 moves upward against the weight of the link 32 and the pressing arm 33, and the link 32 moves upward accordingly. When the foot is released from the input end 36b of the pedal 36, the input end 36b of the pedal 36 moves upward again by the weight of the link 32 and the pressing arm 33, and the action end 36a moves downward together with the link 32.

As shown in fig. 6, the pressing arm 33 is configured to: the arm members 41 have end portions rotatably connected to each other by a connecting shaft 40. The arm members 41 are each configured by providing side plate portions 41b on both side edges of a long flat plate-shaped substrate portion 41a, and are connected to each other by disposing a connecting shaft 40 across both side plate portions 41 b. A pressing roller (pressing member) 42 is provided to the coupling portion of the two arm members 41. The pressing roller 42 has a cylindrical shape centered on the connecting shaft 40 and is relatively rotatable around the axial center of the connecting shaft 40. The outer diameter of the pressing roller 42 is set to: the outer peripheral surface of the pressing roller 42 is always projected outward from the substrate portion 41a of the arm member 41 between the inoperative position where the two arm members 41 are linearly arranged and the operative position where the two arm members 41 are arranged in a bent shape. However, the outer diameter of the pressing roller 42 is set to be smaller than the gap secured between the receiving surface 31c of the receiving member 31 and the depth surface 13a of the front end frame 13 when the door body 20 is closed. The pressing arm 33 is provided with support connection portions 33a at both end portions. The support connection portions 33a are used to rotatably support the pressing arms 33 by the pivot shafts 34 parallel to the coupling shaft 40, respectively.

One end of the pressing arm 33 is connected to the arm connecting portion 32a of the link 32 via a pivot 34, and the other end is attached to a portion on an upper end extension line of the link 32 on the depth surface 13a of the front end frame 13 via a support bracket 43. The support bracket 43 has support plate sections 43b on both sides of the reference plate section 43a, and the two support plate sections 43b are inserted through the pivot shaft 34 so as to be spanned by the reference plate section 43a, and the end of the pressing arm 33 is rotatably supported on the depth surface 13a of the front end frame 13 by screwing the mounting screw S through the reference plate section 43 a.

The mounting support bracket 43 is positioned at a height such that the two arm members 41 are in the inoperative position when the connecting rod 32 is disposed at the lowermost position. At this time, the outer peripheral surface of the pressing roller 42 is in contact with the depth surface 13a of the front end frame 13. When the connecting rod 32 is moved upward from this state, the two arm members 41 are gradually bent around the connecting shaft 40, and the pressing roller 42 projects in a direction away from the front end frame 13. Further, the dimensions of the two arm members 41 in the longitudinal direction are set to: when it is arranged at the inoperative position, the pressing roller 42 is opposed to a lower portion thereof with respect to the receiving surface 31c of the receiving member 31; and when it is arranged at the operating position, the pressing roller 42 is opposed to the upper side portion thereof with respect to the receiving surface 31c of the receiving member 31.

The receiving member 31, the connecting bar 32, and the pressing arm 33 constituting the face material opener 30 are made of a rigid member such as a metal such as a steel material or a hard resin so as not to be easily deformed even when an external force is applied thereto.

In the door/window including the opening device 30 configured as described above, when the pedal 36 is not operated as described above, the pressing arm 33 is in the non-operating position because the link lever 32 is disposed downward as shown in fig. 3 to 8. Therefore, when the door 20 is moved in the closing direction, the pressing arm 33 and the receiving member 31 do not come into contact with each other, and the door 20 can be disposed at the closing position. As shown in fig. 2 (a), the state in which the door 20 is at the closed position is a state in which the front end surface 20c of the door 20 is accommodated in the recess 13d beyond the depth surface 13a of the front end frame 13 and no linear gap in the depth direction is generated between the door 20 and the front end frame 13. In a state where the door 20 is disposed at the closed position, ventilation between the passage and the room is suppressed, and the passage and the room can be blocked while ensuring necessary airtightness. In the closed position, the front end face 20c of the door 20 does not necessarily have to be in contact with the front end frame 13 in the recess 13 d.

When the input end portion 36b of the pedal 36 is depressed downward from the state in which the door 20 is at the closed position, the pressing roller 42 facing the receiving member 31 moves in a direction away from the front end frame 13, and the receiving surface 31c of the receiving member 31 presses the door 20 in the opening direction. That is, the door 20 disposed at the closed position can be moved to the open position without touching the handle 21 provided to the door 20. Therefore, for example, if the pressing roller 42 is set to protrude approximately 100mm from the depth surface 13a of the front end frame 13 when the link lever 32 is disposed at the uppermost position, the door 20 can be opened to the fully opened position by inserting the body into the gap formed between the front end frame 13 and the door 20. As a result, if the door and window is installed in a room where many people get in and out, it is possible to avoid a sanitary problem, and it is possible to open the door 20 even when both hands are occupied with the held objects, which is very advantageous in terms of convenience of use.

When the foot is removed from the pedal 36 regardless of the open/close state of the door 20, the link 32 moves downward by the weight of the link 32 and the pressing arm 33, and the pressing arm 33 returns to the non-operating state. Therefore, the pressing arm 33 protruding when the door 20 is opened does not obstruct the entry and exit, and the opening area when the door 20 is opened does not decrease greatly. Further, since there is no need to provide a return means using an elastic force such as a spring between the pedal 36 and the pressing arm 33, the number of parts can be reduced and the operating force when the door 20 is opened can be reduced.

All the components of the face material opener 30 are always exposed to the outside of the housing 10. Therefore, even when the existing door window is additionally installed, the maintenance work can be easily performed without requiring a complicated work. Further, the closed position of the door body 20 with respect to the frame body 10 does not change before and after the attachment of the face opener 30, and the original airtightness ensured between the passage and the room can be maintained even after the attachment of the face opener 30.

In addition, in the above-described embodiments, the door and window provided on the wall of the room that separates the passage from the room is exemplified, but the present invention is not limited thereto. For example, the present invention may be applied to a door or window provided in a wall body in a room that separates a room from a room, or may be applied to a door or window provided in a wall body that separates an indoor space from an outdoor space. In this case, the door body is not necessarily required as the surface material, and the surface material may be a surface material having a frame around the glass plate. Further, the housing may be provided with only one surface member, or may be provided with a plurality of surface members such as a sliding window. Further, the surface material does not necessarily need to be supported so as to be openable and closable by a door window pulley provided at the lower end portion, and may be of a top-hung type. In this case, the lower frame does not need to be provided as the housing.

In the above-described embodiment, the recessed portion is formed in the depth surface of the front end frame, and the front end portion of the door body is accommodated in the recessed portion when the door body is disposed at the closed position.

Further, in the above-described embodiment, the receiving member is provided only on one side surface of the surface member, but the receiving member may be provided also on the other side surface, and the pressing member and the link mechanism may be provided so as to press the receiving member on the other side surface. Further, the receiving member does not need to be configured as a member different from the handle, and the handle can be shared as the receiving member. Further, since the pressing member and the link mechanism are both disposed on the depth surface of the vertical frame, the size of the protrusion from the main view surface of the door/window can be prevented from increasing, but the pressing member and the link mechanism can also be disposed on the main view surface of the vertical frame. In this case, the operation input unit (pedal) may be configured so as not to protrude toward the opening of the housing. Further, in the above-described embodiment, the protruding end surface of the receiving member is positioned on substantially the same plane as the main viewing surface of the passage side of the vertical frame, but the present invention is not limited thereto.

Further, in the above-described embodiment, since the pressing member is moved to the operating position when the link moves upward, a structure such as a spring for returning the pressing member and the link to the original positions is not necessary, but the pressing member may be moved to the operating position when the link moves downward. In this case, a flexible member such as a wire or a chain may be used as the link mechanism. The operation input unit does not necessarily have to be a pedal type. Further, when the pressing member including the two arm members is applied, the two arm members are arranged linearly with respect to each other in the non-operating position in the above embodiment, but the two arm members in the non-operating position do not necessarily need to be linearly arranged as long as the door body can be arranged in the closing position.

As described above, the surface material opener according to the present invention is a door/window surface material opener including a frame body and a surface material, the frame body having a horizontal frame and a vertical frame; the surface material opener is disposed so as to be movable in the extending direction of the lateral frame, and includes: a receiving member provided on the surface material in a state of protruding from at least one side surface of the surface material; a pressing member disposed at a position facing the receiving member; and a link mechanism having one end connected to the pressing member and an operation input portion at the other end, the link mechanism moving relative to the vertical frame when the operation input portion is operated to press the pressing member.

According to the present invention, since the receiving member is provided on the surface of the surface material and the pressing member presses the receiving member, airtightness between the depth surface of the surface material and the depth surface of the vertical frame can be ensured without accommodating the pressing member in the vertical frame. Further, the pressing member or the link mechanism needs to be disposed between the upper frame and the lower frame with little space. As a result, even when the existing door/window is additionally installed, a troublesome work is not required, and a large reduction in the opening area when the surface material is opened can be avoided.

In the above face material opener of the present invention, the link mechanism is configured to: the pressing member is provided with a link rod that moves up and down along the vertical frame, and presses the pressing member when the link rod moves upward.

According to the present invention, the pressing member can be returned to the original position by moving the link downward by its own weight as long as the operation force to the operation input portion is removed. Therefore, a member such as a return spring for returning the pressing member to the original position after the pressing movement is not required, and the number of components can be reduced.

In the face material opener of the present invention, the link lever extends downward from the pressing member, and the operation input unit is connected to a lower end portion of the link lever.

According to the present invention, the operation input unit may be a foot-operated type, and the surface material may be opened even in a situation where both hands are occupied, for example.

The door and window related to the invention is also provided with the plane materiel opener.

According to the present invention, since the receiving member is provided on the surface of the surface material and the pressing member presses the receiving member, airtightness between the depth surface of the surface material and the depth surface of the vertical frame can be ensured without accommodating the pressing member in the vertical frame. Further, the pressing member or the link mechanism need not be provided between the upper frame and the lower frame without a gap. As a result, even when the existing door/window is additionally installed, a troublesome work is not required, and a large reduction in the opening area when the surface material is opened can be avoided.

In the door/window according to the present invention, the pressing member and the link mechanism are provided on the depth surface of the vertical frame.
