Description

  The present invention relates to a hanging tool, a hanging device, and a building opening structure for hanging a fence, a greening net, or the like in front of a building window.

  2. Description of the Related Art Conventionally, in order to cover an opening of a house window or the like with a screen such as a awning or an awning, a configuration is known in which a suspending device capable of suspending the screen is provided outside the opening. This type of suspension device is provided at a position spaced apart from the opening by a predetermined distance, thereby providing a screen at a position slightly away from the opening to provide a ventilation space between the screen and the opening. In addition, when the screen is rolled up, interference with the opening can be prevented. For example, Patent Literature 1 discloses a suspension device including hooks that are fastened to upper end portions of left and right vertical members forming a decorative frame of a window frame via tapping screws. The hook is configured to protrude slightly to the outside of the window from the window surface, but by providing the hook at the tip of the arm protruding from the vertical member, the screen is spaced a certain distance from the window as described above. Can be suspended.

Japanese Patent Laid-Open No. 2005-218466

  However, in the configuration in which the hook is provided at the tip of the arm as described above, the base end of the arm is fastened to the left and right vertical members of the window frame via the tapping screws, so that the screen or the like is suspended. Even when it is not raining or in winter, the arm is kept protruding from the window frame, so that the area of the field of view of the person who looks up from the room to the scenery obliquely above the window frame, such as the sky or night view, etc. In addition to the problem that the scenery cannot be fully enjoyed, the appearance of the building may be noisy and the design of the building may be impaired.

  Therefore, the present invention provides a hanging tool and a hanging device that can reduce as much as possible the area occupied by the view of a person who looks at the scenery obliquely above the window frame, and can maintain the exterior design of the building. The purpose is to do.

  In order to solve this problem, the present inventor has made various studies. Conventionally, in the invention that has been proposed as a device for suspending a screen such as a bag in front of an opening, a device having a use posture separated from the opening to the outside in order to install a screen such as a bag in front of the opening. You can find the common ground that you need it. Further, as the separation distance, a distance is required such that when the screen is rolled up, the roll-shaped screen is not buffered in the opening. Although the configuration in which the arm is attached to the vertical frame of the window next to the window or the decorative cover as in Patent Document 1 is a basic means that can solve such problems, there are the above-mentioned problems. Mounting requires a tool and is difficult unless it is an expert. 2) Since the arm is installed on both sides of the opening, there is also a problem that it is necessary to hang a bag and other screens. Focusing on these problems, we will study a structure that can cover a screen such as a bag while ensuring a certain separation on the front surface of the opening, is easy to install, and can be easily changed to a design-friendly state when not needed. The inventors of the present invention have repeatedly obtained new knowledge that leads to the solution of the problem.

  (1) The present invention is based on such knowledge, and is suspended from an eaves provided at the upper part of the opening formed on the outer wall of the building and capable of suspending a suspended object provided in front of the opening. A hook member comprising a long arm, a hook member provided at a tip of the arm and hanging the object to be suspended, and a state in which the arm of the hook member is horizontal And a supporting member that supports the eaves below the eaves, wherein the supporting member has a use posture in which the hook portion is separated from the opening portion and a housing posture in which the hook portion is brought close to the opening portion. A posture deforming mechanism for deforming the posture of the hook member is provided.

  According to this, since the posture of the hook member can be deformed by the posture deformation mechanism, when the object to be suspended is suspended from the hook portion, the hook member is set to the use posture so that the hook portion is opened. The object to be hung can be hung from the hook portion. Moreover, by setting the hook member in the housing posture, the hook portion can be brought into a state of being close to the opening (a state along the eaves), and the protrusion amount of the hook member from the opening to the outside can be significantly reduced. Can do. As a result, it is possible to prevent the hook member from occupying one area of the field of view of a person who looks at the scenery obliquely above the opening as if looking up from the room.

  (2) Further, the posture deformation mechanism includes a shaft member that protrudes perpendicularly to the bottom plate of the eaves, a cylindrical body that supports the proximal end portion of the hook member and is rotatably fitted to the shaft member. It is preferable to provide.

  According to this, the cylinder can be rotated around the axis of the shaft member, and the hook member attached to the cylinder can also be rotated around the axis of the shaft member. For this reason, it is possible to easily change the posture of the hook member between the use posture and the storage posture by simply rotating the hook member.

  (3) Further, a load acting on the bottom plate from the cylindrical body by suspending the suspended object on the hook portion of the hook member interposed between the cylindrical body and the bottom plate of the eaves on the support member. It is preferable to provide a load distribution member that disperses and transmits to the bottom plate.

  According to this, a large moment acts on the cylindrical body by suspending the suspended object on the hook portion, but the pressing force that presses the bottom plate due to the moment is applied via the load distribution member. Thus, the pressure is transmitted to the bottom plate, and it is possible to avoid the concentration of the pressing force on the local part of the eaves and to disperse the pressure remarkably. As a result, it is possible to prevent the eaves from being damaged due to the suspended object being suspended from the hook portion.

  (4) Moreover, as another specific means for solving the above-described problem, a suspension device according to the present invention includes an eaves provided at an upper part of an opening formed in an outer wall of a building, A suspension tool capable of suspending a suspended object provided in front of the opening, and the suspended tool is provided with an arm formed in a long shape and a tip of the arm, and the suspended object. A hook member provided with a hook part for suspending a hanger, and a support member for supporting the hook member under the eaves in a state where the arm of the hook member is horizontal, and the hook member is connected to the opening from the opening. A posture deformation mechanism is provided for deforming the posture of the hook member between the separated usage posture and the housing posture in which the hook portion is brought close to the opening, and the support member and the eave are provided in the opening. Slide machine that can slide hook members along It is characterized in that is provided.

  According to this, the amount of protrusion of the hook member can be adjusted, and the relative position of the hook portion with respect to the opening can be changed. As a result, when the hanger is obstructing the field of view, not only can the hanger be slid out of the field of view, but also the hung object can be hung. The position with respect to the opening can be arbitrarily set. In addition, when the object to be suspended is a screen that covers an opening such as a bag, there is a case in which a hook portion that can hook the hook portion is provided on the screen side, but the position of the hook portion varies depending on the type of the screen. It is. According to the present invention, since the hook member can be translated along the opening, it is possible to cope with any of various suspended objects having hook portions at different positions.

  (5) Moreover, it is preferable that the said slide mechanism is provided with the rail which follows the said opening part formed in the bottom plate of the said eave, and the fitting member which is provided in the said supporting member and fits into the said rail. .

  According to this, the support member can be moved along the rail, and the position of the hook member can be easily changed.

  (6) The rail includes a pair of rail pieces facing each other with at least a gap larger than the width of the shaft of the support member, and an introduction portion provided with a width larger than the gap. And the fitting member is spaced at least equal to the thickness of the pair of rail pieces between a contact portion that contacts the surfaces of the pair of rail pieces in a state of being engaged with the shaft body, and the corresponding contact portion. And the engagement piece has a width smaller than the introduction portion and a width larger than the gap between the pair of rail pieces. Preferably it is.

  According to this, by moving the contact portion toward the rail while the engagement piece is inserted into the introduction portion, the contact portion contacts the surface of the pair of rail pieces, and the engagement piece A shaft body will be located between a pair of rail pieces in the state contact | abutted to the back surface of a pair of rail piece. As a result, the shaft body of the support member is maintained in the posture by the contact portion and the engagement piece that sandwich the pair of rail pieces, and is guided to move by the pair of rail pieces. The cylindrical body and the hook member can be moved by moving the shaft body along the piece.

  (7) Furthermore, it is preferable that a male screw is formed on the outer peripheral surface of the shaft body, and a screwing portion having a female screw on the inner periphery is formed on the engagement piece.

  According to this, the engagement piece can be screwed onto the shaft body. Therefore, by tightening the shaft body on the engagement piece in a state where the shaft body is positioned between the pair of rail pieces, the distance between the contact portion and the engagement piece is narrowed so that the pair of rail pieces are applied. The entire support member can be fixed at this position by tightly sandwiching the contact portion and the engagement piece. Similarly, by loosening the engagement piece and the shaft body, the fixed state of the support member can be loosened, and the support member can be moved again along the rail.

  (8) Further, as another specific means for solving the above problems, the opening structure of a building is provided with the above-described suspension device.

  ADVANTAGE OF THE INVENTION According to this invention, while the area | region which occupies the view field of the person who looks at the scenery diagonally above a window frame can be reduced as much as possible, the exterior design of a building can be maintained.

It is a figure which shows one Embodiment of this invention, and is the perspective view looked up from the downward direction of the hanging tool attached to the bottom plate of the eaves and the said bottom plate. It is a perspective view from the upper part of a hanging tool. It is a figure which expands and shows the fitting member and its vicinity of a hanging tool. It is a side view of the hanging tool at the time of use attached to the eaves (small sash member above the aluminum sash outer frame) and the bottom plate of the eaves. It is a side view of the hanging tool attached to the bottom board of the eaves (shutter box) of another shape, and the said bottom board which shows other embodiment of this invention.

  Hereinafter, the configuration of the present invention will be described in detail based on an example of an embodiment shown in the drawings.

  1 to 5 show an embodiment of a hanging tool and a hanging device according to the present invention. The hanging tool 1 according to the present invention is attached to the eaves 22 when the eaves 22 provided on the outer wall of the building 20 is provided above the openings 21 such as windows formed by an aluminum sash outer frame. This is an instrument capable of suspending the suspended object 30 provided in front of the portion 21. The suspended object 30 includes, for example, a rollable screen such as a basket or an awning that can be rolled up, and a greening net provided in front of the window to greenen the window. The hanging tool 1 of the present embodiment includes a hook member 2 and a support member, and is further provided with a posture deformation mechanism 8 for deforming the posture of the hook member 2.

  In the present embodiment, the “eave” is projected in a bowl shape above the opening of a window or the like, and the eaves formed by the roof, as well as a small fence member or shutter box that projects in front of the window. including.

  Here, in the present embodiment, as an example of the eaves 22, a gavel member installed above an aluminum sash outer frame window as the opening 21 is employed. The small eaves member has an eave 22 having a bottom plate 22a that forms the back of the eave, and a rail 23 along the opening is formed on the bottom plate 22a. Such eaves 22 is manufactured by, for example, extrusion molding, and the rail 23 is formed with a pair of rail pieces 24 facing each other with a gap having a predetermined width (see FIG. 1). . The pair of rail pieces 24 have a cross-sectional shape that is folded inward so as to face each other (see FIG. 4). Further, an introduction portion 25 having a width larger than the interval between the pair of rail pieces 24 is formed in the middle of the rail 23 (see FIG. 1). In the hanging device 10 of the present embodiment, a part of the hanging tool 1 (specifically, an engagement piece 7b of the fitting member 7 described later) is inserted into the introduction portion 25 and moved along the rail 23. Thus, the hanging tool 1 can be hooked on the eaves 22.

  The hook member 2 includes an arm 2a and a hook portion 2b (see FIG. 2 and the like). The arm 2a is composed of a plate-like long member whose cross section is a vertically long rectangle, for example, but may be an arm 2a having a non-linear shape such as a curved shape in the vertical direction. In addition, a hook portion 2b is formed near the tip of the arm 2a. The hook portion 2b is a notch for hanging a part of the suspended object directly or indirectly via a string or the like. The vicinity of the lower end of the hook portion 2b is processed so as not to be sharp, such as a rounded shape. In addition, although the hook part 2b of the shape cut | disconnected diagonally toward the front-end | tip is shown in FIG. 4, this is only an example and the cut | notch shape of the hook part 2b can be changed suitably as needed.

  The support member 3 is a member that supports the arm 2a of the hook member 2 under the eaves in a horizontal state. The support member 3 includes a posture changing mechanism for changing the posture of the hook member 2 between a use posture in which the hook portion 2b is separated from the opening portion 21 and a housing posture in which the hook portion is close to the opening portion. 8 is provided. For example, in this embodiment, the posture deformation mechanism 8 is configured by a mechanism that uses a fastening force when a bolt and a nut are screwed together.

  If it demonstrates concretely, the attitude | position deformation | transformation mechanism 8 of this embodiment will be the shaft member 4 which protrudes in the substantially perpendicular | vertical form with respect to the baseplate 22a of the eaves 22, and the base end part 2c of the hook member 2 integrated by welding, for example. It is comprised as a mechanism provided with the cylindrical body 5 which supports. The shaft member 4 can be constituted by, for example, a bolt or the like in which a male screw (shaft body) 4a and a head (knob) are integrated (see FIG. 4 and the like). The diameter of the male screw (shaft body) 4 a is smaller than the gap between the rail pieces 24 of the rail 23. Further, the male screw (shaft body) 4a of the shaft member 4 is inserted into the cylindrical body 5, and supports the cylindrical body 5 in a rotatable state (see FIG. 2 and the like). It is preferable that the shaft member 4 and the cylinder 5 are aesthetically treated on their appearance. For example, in this embodiment, by making the diameter of the head of the shaft member 4 equal to the diameter of the cylindrical body 5 and further having the same surface finish, it is possible to feel an integrated feeling in both the use posture and the housing posture Yes.

  It is also preferable to provide a seat on the head (knob) of the shaft member 4 and interpose a washer 4b between the head and the cylinder 5 (see FIG. 4). In the present embodiment, a spring washer (spring washer) is used as the washer 4b to function as a loosening stop for the head (knob) of the shaft member 4. Further, the washer 4b may be made invisible from the outside so as to improve the sense of unity between the head of the shaft member 4 and the cylindrical body 5. In the present embodiment, an annular recess 4c is formed in the head (knob) of the shaft member 4 to a depth that can accommodate the washer 4b (see FIG. 4). Of course, the recess 4b may be formed only in the cylinder 5 or formed by providing a groove having a depth about half the thickness of the washer 4b in each of the head of the shaft member 4 and the cylinder 5. May be.

  A fitting member 7 that is fitted to the rail 23 of the eave 22 is provided at the tip of the shaft member 4 (see FIG. 3 and the like). For example, the fitting member 7 of the present embodiment has at least the thickness of the rail piece 24 between the contact portion 7a that contacts the surfaces of the pair of rail pieces 24 in a state of being engaged with the shaft body 4a. An engagement piece 7b that engages with the shaft body 4a with an equal interval is provided (see FIG. 3). The contact portion 7a is made of a plate-like member formed in a rectangular shape, for example. The engaging piece 7 b is formed in, for example, a rectangular shape so as to have a width smaller than the introduction portion 25 of the rail 23 and a width larger than the gap of the rail piece 24 so as not to fall off from the rail 23. The engaging piece 7b is formed with a boss 7d that protrudes on the opposite side of the abutting portion 7a. Inside the boss 7d and the engaging piece 7b, a threaded engagement with the male screw of the shaft body 4a is formed. A portion (female screw) 7c is formed (see FIG. 3).

  Thus, the slide mechanism 9 for allowing the position of the suspension tool 1 to be changed by sliding the suspension tool 1 is constituted by the rail 23 and the fitting member 7 fitted to the rail 23. In the suspension device 10 provided with such a fitting member 7, the abutting portion 7 a is moved by moving the fitting member 7 toward the rail 23 with the engaging piece 7 b inserted into the introducing portion 25. Is in contact with the surfaces of the pair of rail pieces 24, and the engagement piece 7b is in contact with the back surfaces of the pair of rail pieces 24, and the shaft body 4a is positioned between the pair of rail pieces 24 (FIG. 4). Etc.). In such a case, the posture of the shaft body 4a of the support member 3 is maintained by the contact portion 7a that holds the pair of rail pieces 24 and the engagement piece 7b, and further, the pair of rail pieces 24 in the rail groove direction. Guided. Therefore, by moving the shaft body 4a along the pair of rail pieces 24, the cylindrical body 5 and the hook member 2 can be slid to arbitrary positions, and the position of the hook member 2 can be easily changed. it can.

  Further, the support member 3 includes a load distribution member 6 that disperses the concentration of a load acting on the bottom plate 22a from the cylinder 5 when the suspended object 30 is suspended from the hook portion 2b of the hook member 2. Is preferred. For example, in the present embodiment, the above-described contact portion 7a is formed in a flat plate shape extending in the longitudinal direction, and the extended portion protrudes in the opposite direction to the arm 2a (the direction in which the opening 21 is present). It is made to function as the load distribution member 6 interposed between the bottom plate 22a (refer FIG.3, FIG.4 etc.). When the suspended object 30 is suspended from the hook portion 2b, a moment acts in the vicinity of the support member 3, and is concentrated and locally caused by the moment on the bottom plate 22a of the eaves 22 through the contact portion with the support member 3. A pressing force acts. At this time, the load distribution member 6 of the present embodiment disperses the pressing force acting on the bottom plate 22a to avoid local concentration. According to this, the situation where the bottom plate 22a of the eaves 22 is partially deformed or damaged or it is difficult to stably install the hanging tool 1 on the bottom plate 22a of the eaves 22 can be suppressed. For this reason, it is preferable that the contact part 7a which is a load distribution member is formed by making the contact area of the eaves 22 with the bottom plate 22a as large as possible.

  According to the hanging tool 1 and the hanging device 10 of the present embodiment described above, it is easy to attach the hanging tool 1 to the eaves 22. That is, the hanging tool 1 can be attached to the eaves 22 without a tool, and can be easily attached even if it is not an expert such as a person engaged in the attaching work. In addition, the work for removing the hanging tool 1 from the eaves 22 is also easy.

  In addition, according to the hanging tool 1 and the hanging device 10 of the present embodiment, a hook attached to a suspended object 30 such as a screen (for example, an S-shaped hardware attached to a bag) is directly suspended. Can be lowered. That is, in the case of a fixed hanging tool that cannot change the position and orientation of the hook portion 2b, the distance between the left and right hook portions 2b and the distance between the hooks of the suspended object 30 generally do not match. For example, it is unavoidable to hook a hook on the hanging tool and suspend the object 30 to be hung on the hook. However, according to the hanging device 10 of this embodiment, the hanging tool 30 Since the hanging tool 1 can be slid in accordance with the hook interval, it is not necessary to use a hook or the like, and there is no need to prepare a hook or the like.

  Moreover, according to the suspending tool 1 of the present embodiment, the cylinder 5 can be rotated around the shaft (shaft body 4) of the shaft member 4, and the hook member 2 attached to the cylinder 5 is also a shaft member. It can be rotated around 4 axes. For this reason, just by rotating the hook member 2, the posture of the hook member 2 can be easily and continuously changed between the use posture and the storage posture. For example, in the winter when the suspended object 30 such as a kite is not necessary, the hook member 2 is rotated so that the hook member 2 is parallel to the opening (for example, the window) 21, and the protrusion from the eave 22 is eliminated. The housing posture can be such that the presence of the hanging tool 1 is not conspicuous. According to this, even when the hanging tool 1 is attached, the protruding amount from the opening 21 of the hook member 2 of the hanging tool 1 can be remarkably reduced, and the opening 21 or eaves of the building 20 can be reduced. The appearance design in 22 can be maintained in a preferable state in which the hanging tool 1 is not attached.

  Moreover, the hanging tool 1 of this embodiment is particularly suitable when applied to the eaves 22 having the rails 23 as described above. For example, if the eaves 22 are provided with groove-like ribs for improving the strength at the time of extrusion molding on the bottom plate 22a, the slide mechanism for the suspension device 10 is formed by forming the introduction portion 25 in the rib-like portion. 9 can function as the rails 23 constituting the motor 9. Alternatively, even in the existing eaves 22 having such groove-shaped ribs, it is advantageous in that the above-described hanging tool 1 can be used with a small amount of processing such as forming the introduction portion 25 in part. is there.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in each of the above-described embodiments, a concrete example of the suspended object 30 is exemplified by a rollable or awning screen such as a screen, but the present invention is not limited to this. In addition, a lantern, a planter, a laundry The hanging tool 1 and the hanging device 10 according to the present invention can be applied as long as it can be hung, such as a hanging object.

  Moreover, although the hanging tool 1 etc. were demonstrated using the expression "horizontal" in this specification, horizontal here is not restricted to the case where it is completely horizontal. As is apparent from the above description, in the hanging tool 1, when the hook member 2 is in the use posture, it is important that the hook portion 2b is in a posture sufficiently separated from the opening 21 of the building 20. Yes, the relative position of the hook portion 2b with respect to the building 20 or the like at this time may be set as appropriate. In short, if the position of the hook portion 2b to which the suspended object 30 is directly hooked can be appropriately changed within a predetermined range, the arm 2a of the hook member 2 is curved and not completely horizontal, You may be bent.

  In the above-described embodiment, the arm 2a made of a plate-like long member whose cross section is a vertically long rectangle and the hook portion 2b formed by cutting near the tip of the arm 2a are exemplified (see FIG. 4). These are also only preferred examples, and various forms such as an arm 2a having a hook-like hook portion 2b formed by processing a steel wire having a circular cross section (see FIG. 5) can be used.

  Although not particularly illustrated, it is also preferable that the hook member 2 can be expanded and contracted. In such a case, the range of the relative position of the hook portion 2b that can be set is further expanded, for example, the hook portion 2b is further separated from the opening portion 21 in accordance with the size and shape of the suspended object 30. The structure in which the hook member 2 can be expanded and contracted is a mechanism in which the portion including the hook portion 2 b of the hook member 2 is divided, or a mechanism capable of sliding by a sliding pair, or the hook member 2 can be slid relative to the support member 3. It can be configured by a mechanism that makes 2b movable.

  In the above-described embodiment, the case where the present invention is applied to the eaves 22 having the flat bottom plate 22a has been described. However, the present invention is naturally applied to the eaves 22 having a different structure. Is possible. For example, when the lower end portion of the eave 22 by the shutter box that can store the roll-up type shutter 26 has a substantially crank shape in cross section, it is preferable to apply the hanging tool 1 having a structure that can use the shape (see FIG. 6). That is, in this case, the hanging tool 1 is slidably mounted using the rail 23 formed on the horizontal portion of the bottom plate 22a having a crank shape, and the moment load is applied using the vertical portion 22a1 of the bottom plate 22a. Can be dispersed and buffered. That is, in such a case, the cylindrical body 5 of the hanging tool 1 can be directly received by the vertical portion 22a1 of the bottom plate 22a, so that the load is not required without using the load distribution member 6 as described above. It is possible to avoid local concentration.

  The present invention is not only applicable to newly constructed or designed eaves with openings, but is also preferable in that it can be applied to eaves with openings in existing ordinary houses and buildings.
