Description

  The present invention relates to a vertical blind provided with a cushioning material between a carrier of a head rail and a louver, and a method for assembling the vertical blind.

  Conventionally, there are two types of blinds: horizontal blinds with horizontal louvers and vertical blinds with vertical louvers. Among these, the vertical blind is provided with a head rail extending in the horizontal direction, and a plurality of carriers are disposed in the head rail. Each carrier passes through a screw-like transport shaft extending along the head rail, the transport shaft is rotated by a transport shaft rotation operation means, and the carrier is moved forward and backward along the head rail. At this time, the louvers are arranged at equal intervals on the head rail when a plurality of carriers are advanced (deployed), and the louvers are arranged on one end side of the head rail if the blind is a single-opened blind when retracted (stored). If it is stored and double-opened, half of the louvers are distributed and stored on both ends of the blind.

Each carrier is provided with a hook having a rotation axis in the vertical direction, and a louver is suspended from the hook. In addition, an angle adjusting shaft extending along the head rail along with the conveying shaft passes through each carrier, and the rotation of the angle adjusting shaft rotating around the horizontal axis is transmitted to the support shaft around the vertical axis in each carrier. A rotation transmission mechanism is provided. Then, when the angle adjustment shaft is rotated by the rotation operation means of the angle adjustment shaft, the support member of each hook is rotated, each louver suspended from the support member is rotated in the same phase, and the direction of each louver is changed to the head. The blind is switched between being shielded and unshielded by making it substantially parallel to the rail or rotating it so as to be vertical.
In addition, in the carrier of Patent Document 1, a louver (slat in Patent Document 1) is blown by wind so that a hook for suspending the louver rotates so that an opening angle (phase angle) of the louver does not easily change. A carrier having a hook provided with rotational resistance is disclosed.

  In Patent Document 2, as described above, a louver is suspended through a hook member supported by a carrier. In this way, each louver is hung on the carrier hook, so the louver is beaten by the wind, or is twisted or tilted when an animal or person such as a pet comes into contact with it. May be loaded. Generally, various materials such as resin, cloth, and wood are used for the louver. However, if the material is a flexible resin, the louver itself absorbs the impact even if the louver is twisted or bent. Therefore, almost no load is transmitted to the hook.

  However, if the louver is made of a material such as wood or metal, because of its rigidity, a load is directly transmitted from the louver to the hook when subjected to an impact. In particular, the hook is a part of the support member that is connected to the mechanical unit disposed inside the carrier. When an external force is applied in an oblique direction or a shearing direction, a large stress is concentrated on the support member that protrudes downward from the carrier. . In general, a support member having a hook is formed of resin, metal, etc. When a strong external force is applied, not only a resin hook but also a metal member in a hook (support member) or carrier The mechanical part may be damaged.

Transmission to the support member of the carrier is suppressed.
The support member of the vertical blind has a rotation resistance that rotates when a rotational force of a certain level or more is applied, and the deformation force that deforms the buffer member is initially greater than the rotation resistance force of the support member. When the deformation of the buffer member is small, the buffer member can be formed to be larger than the rotational resistance of the support member.
The buffer member of the vertical blind is preferably formed of silicon rubber having a tear strength of 25 to 34 N / mm.
The hanger member of the vertical blind includes an upper connector suspended from a support member of the carrier, a lower connector forming an attachment portion of the louver, and the buffer member provided between these upper and lower connectors.

The mounting portion of the buffer member of the upper coupling tool or the mounting portion of the buffer member of the lower coupling portion is sandwiched between the front and rear surfaces of the cushioning member. It is preferable to consist of parts.
It is preferable that a recess for accommodating the hanger member is formed at the upper end of the louver of the vertical blind.
In order to achieve the above object, the vertical blind assembling method of the present invention connects the buffer member and the upper connector by connecting the lower end of the upper connector to the upper end of the buffer member. Connecting the lower end of the buffer member by connecting the upper end of the lower connector to the lower end of the buffer member; and connecting the lower end of the lower connector to the upper end of the louver; A step of suspending, and a step of suspending the upper end portion of the upper connector on a support member of a carrier movable with respect to the head rail.

When moving, the roller 8 of the carrier 6 is guided by the roller guide 3 described above, and the main body 7 is moved in a stable posture. The forward / backward movement of the carrier 6 is performed by the clockwise or counterclockwise operation of the transfer rope 19 described above.

A support member 10 made of synthetic resin is formed on the main body 7 of the carrier 6 so as to protrude from the inside of the main body 7 downward to the bottom surface. The support member 10 is engaged with the angle adjusting shaft 16 via a rotation transmission mechanism (not shown) provided inside the main body 7 and is supported by a bearing 9 provided at the bottom of the main body 7 so as to face in the vertical direction. Can be rotated about a specified axis. The rotation of the support member 10 is performed by a clockwise or counterclockwise rotation operation of the angle adjusting rope 20 described above.
The portions of the support member 10 that protrude downward from the main body 7 are a pair of sandwiching pieces 21a and 21b. The sandwiching pieces 21a and 21b are integrally connected at the base end on the bottom surface side of the main body 7, and The lower end side can be opened by the elastic force of the resin. The sandwiching pieces 21a and 21b are arranged substantially in parallel, and the lower end of one sandwiching piece 21a is a pressing portion 23 that protrudes inward (the sandwiching piece 21b side), and the holding portion of the other sandwiching piece 21b. At an intermediate position higher than 23, a hook 22 having an upward claw is formed.

5 and 6 show a hanger member 31 that is an important member of the present invention, and the hanger member 31 is disposed between the support member 10 of the carrier 6 and the louver 5, in other words, supports the louver 5. It is an intermediate member for hanging on the member 10.
In the present embodiment, the hanger member 31 includes an upper connector 32, a lower connector 33, and a buffer member 34 disposed therebetween. Among these, the upper connector 32 is made of a metal that is relatively easy to process, such as aluminum, and the upper end portion is formed with a hook piece 35 of a substantially rectangular tongue-like plate material. A long hole 36 extending in the lateral direction is penetrated in the upper end portion of the hooking piece 35, and the long hole 36 is formed to be hooked on the hook 22 described above. A gripping portion 37 is formed at the lower end of the hooking piece 35, and the gripping portion 37 has an arc (tunnel) shape with a slightly larger peripheral angle than the semicircle, and the lower end side is opened. Is formed. A circular protrusion 43 at the upper end of the buffer member 34 to be described later is tightly attached to the grip portion 37.

The lower connector 33 is also formed of a metal that is relatively easy to process, such as aluminum, and a grip 38 is formed at the upper end. The grip 38 is different from the grip 37 of the upper connector 32 in the direction of the opening, and the opening is positioned on the upper side. In addition, the gripping portion 38 is formed in an arc shape that is slightly larger than a semicircle and is formed in the entire width direction of the lower connector 33, and the gripping portion 37 has the same size and shape. The lower end portion of the buffer member 34 is tightly attached to the grip portion 38.
On the lower side of the lower connector 33, a narrowed portion 39 having a U-shaped cross section with an opening on the lower side is formed. A claw 40 is formed at each lower end portion of the inner surface of the narrow attachment portion 39 along the lower end portion. As shown in FIG. 6, the interval between the top surfaces 39a of the narrow portions 39 is substantially equal to the thickness of the louver 5, and before the narrow portions 39 are assembled, the lower end side of the inner surface of the narrow portion 39 is obliquely outward. When the louver 5 is inserted, it is pressed from both sides, and the louver 5 is narrowed.

  The buffer member 34 connected between the upper and lower connectors 32, 33 has a rectangular flat plate shape, circular protrusions 43, 44 are formed on the upper edge and the lower edge, and the outer side of the flat surface of the flat plate part 46. It is formed to protrude. In the present embodiment, as an example, the width is 18 mm, the thickness is 4 mm, and the height is 30 mm, and the radius of the circular protrusions 43 and 44 is 2.35 mm. The outer shape of these circular protrusions 43 and 44 is formed in a shape corresponding to the inner surfaces of the gripping portions 37 and 38 of the upper and lower connectors 32 and 33. By inserting the circular protrusions 43 and 44 into the gripping portions 37 and 38 and crimping the gripping portions 37 and 38, the upper connector 32, the buffer member 34 and the lower connector 33 of the hanger member 31 are connected together. Become.

As for the material of the buffer member 34, a material that becomes a buffer material between the support member 10 and the louver 5 when the louver 5 is suspended from the support member 10 and has a high resilience due to deformation is used. In this respect, elastic members such as rubber and resin, metals such as stainless steel and iron with a thin material, coil springs and leaf springs can be used, and cloths can be used depending on the material. Of these materials, silicon rubber is particularly preferable, and is excellent in heat resistance, cold resistance, weather resistance, and the like. In this embodiment, so-called high tear silicone rubber reinforced with silicone rubber is used.
The plate-like high tear silicone rubber (hereinafter, also simply referred to as “silicon rubber”) has a strong tensile force, and there is no substantial deformation when the louver 5 is suspended. Moreover, the upper end and the lower end of the silicon rubber can be supported and bent easily into a U shape. When torsion is applied, the initial load is twisted, but the torsional force gradually increases to draw a parabola according to the torsion angle, and when the torsion angle exceeds 90 degrees. Critically suddenly a large force is required, making it difficult to deform. When the twisting force is released, it has a characteristic of returning to its original shape so as to repel. In the present embodiment, a silicon rubber having a tear strength of 25 to 34 N / mm and a tensile strength of 7.3 to 11.5 M / Pa is used, and a normal silicon rubber has a tear strength of about 9.8 N / mm. Stronger than. Such silicon rubber can bend in any direction when the louver 5 is suspended.

  In the present embodiment, the louver 5 is made of a material having rigidity that is not deformed by an external force, and a metal, a hard resin, a plate material, or the like is used. In the present embodiment, wood is used. The louver 5 has a concave groove 45 formed in the center in the width direction of the upper end portion, and the buffer member 34 of the hanger member 31 is accommodated in the concave groove 45. The bottom of the groove 45 is clamped by the narrow portion 39 of the lower connector 33 of the hanger member 31, and is prevented from coming off by the claw 40. In the state assembled to the hanger member 31 and the louver 5, the hanger member 31 may be completely stored in the concave groove 45, and the hook piece 35 of the upper connector 32 protrudes above the concave groove 45. You may do it.

[Example of vertical blind assembly method]
First, the hanger member 31 is assembled first. That is, the lower gripping portion 37 of the upper connector 32 is inserted into the circular protrusion 43 on the upper end side of the buffer member 34. When inserting, when the clearance of the opening of the lower end of the holding part 37 is small, you may insert so that it may slide from a horizontal direction (the circular protrusion 44 and the holding part 38 are also the same). Then, the gripping portion 37 is pressed from both sides, and the lower end of the gripping portion 37 is crimped so as to bite into the boundary portion between the circular protrusion 43 and the flat plate portion 46 of the buffer member 34, and the upper connector 32 and the buffer member 34 are connected. Connect (the step of connecting the buffer member and the upper connector). In the case of this crimping, it is preferable to eliminate a gap between the outer peripheral surface of the circular protrusion 43 and the inner surface of the gripping part 37 (the same applies to the crimping of the circular protrusion 44 and the gripping part 38).

  Next, the grip portion 38 on the upper end side of the lower connector 33 is inserted into the circular protrusion 44 on the lower end side of the buffer member 34. Then, the gripping portion 38 is pressed from both sides, and the upper end of the gripping portion 38 is crimped so as to bite into the boundary portion between the circular protrusion 44 and the flat plate portion 46 of the buffer member 34, and the lower connector 33 and the buffer member 34 are connected. Connect (step of connecting the buffer member and the lower connector). Thus, the hanger member 31 is completed. Either the upper connector 32 and the buffer member 34 or the lower connector 33 and the buffer member 34 may be connected first.

Next, the bottom of the concave groove 45 of the louver 5 is inserted into the mounting portion 39 at the lower end of the lower connector 33, and the narrow portion 39 is pressed against the surface of the louver 5 from both sides so as to be narrowed to form the inner surface of the narrow portion 39. The nail | claw 40 which carried out is eaten in the surface of the louver 5. Thus, the connection between the hanger member 31 and the louver 5 is completed.
The louver 5 is suspended from the carrier 6 by opening the holding portions 21 a and 21 b of the support member 10 and passing the long hole 36 of the hooking piece 35 of the upper coupling member 33 through the hook 22. At the lower end of the clamping part 21, the louver 5 is supported so as to be clamped between the presser part 23 and the tip of the clamping part 21b (step of hanging the louver).

Thus, the louver 5 is suspended through the hanger member 31. In the state where the louver 5 is suspended, the upper coupling tool 32 of the hanger member 31 is pressed between the presser portion 23 and the clamping portion 21b of the support member 10, so that rattling and swinging of the louver 5 are suppressed. In addition, in a state where the louver 5 is suspended, the louver 5 and the buffer member 34 of the hanger member 31 are aligned so that the surfaces thereof are arranged on the same plane.
In a state where the louver 5 is suspended from the carrier 6 via the hanger member 31, the buffer member 34 does not vibrate the louver 5 up and down due to the tensile strength of the high tear silicone rubber, and swings in the left / right front / rear and rotational direction. I will not let you.

Next, the operation of the vertical blind according to the embodiment of the present invention will be described.
The operation of the vertical blind is the same as that of a general vertical blind. When the louver 5 is developed over the entire length of the head rail 2 or is stored at one end (both ends in the case of a central opening), The transport rope 19 is rotated clockwise or counterclockwise. Due to the rotation of the transport rope 19, the transport shaft 15 rotates forward or backward, and the carrier 6 moves forward or backward together with the louver 5.

When the louver 5 is in the unfolded state and the louver 5 is rotated to bring the blind into an open state or a shielded (closed) state, the angle adjusting rope 20 is rotated clockwise or counterclockwise. When the angle adjusting shaft 16 is rotated forward or reverse by rotation of the angle adjusting rope 20, each louver 5 is rotated in the same phase and positioned at a desired open position or closed position.
At this time, the cushioning member 34 made of silicon rubber is not substantially deformed during rotation, rotates in the same manner as when the hanger member 31 is omitted and is directly suspended from the hook 22, and does not cause unnecessary swinging.

  When an unintended external force is applied to the louver 5, the buffer member 34 of the hanger member 31 serves as a buffer material, and the impact due to the external force applied to the support member 10 is reduced. Specifically, the shock-absorbing member 34, which is a high tear silicone rubber, is bent into a U shape with respect to the bending. Therefore, even if the direction of the lower end of the louver 5 is bent 90 degrees and the louver 5 is horizontal, the shock-absorbing member 34 The support member 10 is not substantially loaded only by bending. Moreover, even if the louver 5 is inclined in the oblique direction, the force applied to the support member 10 in the oblique direction is reduced only by twisting the buffer member 34.

  As described above, each louver 5 can adjust the angle of each louver 5 to the same phase as a whole using the angle adjusting rope 20, but the phase angle can be changed for each louver 5. When individually changing the phase angle of the louver, the user can change the phase angle of the louver 5 by manually holding the louver 5 whose angle is to be changed, rotating the louver in the direction to be rotated, and manually. At this time, the support member 10 provides resistance to the rotation of the support member 10 by a rotation transmission mechanism (not shown) provided inside the carrier 6 so that the louver 5 does not easily rotate by the action of wind or the like, but exceeds a certain level. When the rotational force is received, the support member 10 is idled so that the phase angle of the louver 5 can be changed.

  At this time, if the material of the buffer member is weak like a rubber band, the support member 10 will not idle even if the louver rotates several times. However, if the elastic member has a certain degree of hardness, the rag will not be suddenly deformed like a rigid body when it is twisted to some extent as if the rag has been squeezed. The present invention utilizes this action, and when the louver is rotated around the vertical axis, the buffer member 34 is twisted without reaching the rotational resistance of the support member 10 up to a certain angle. However, if the torsion angle of the buffer member 34 exceeds a certain angle, the buffer member 34 made of silicon rubber becomes difficult to deform, causing the support member 10 to run idle against the rotational resistance of the support member 10, and the louver 5. Can be changed individually.

That is, the deformation force that deforms the buffer member 34 when the buffer member 34 is deformed is smaller than the rotational resistance of the support member 10 at the beginning of the deformation, and becomes larger than the rotational resistance of the support member 10 as the deformation increases. It is important to rotate.
Regarding the torsion angle for rotating the support member, the support member may be rotated in the range of 90 to 360 degrees by changing the elastic force of the buffer member 34. Thus, even if the buffer member 34 is provided, the support member 10 can be idled by the rotation of the louver 5.
In addition, about the louver which changed the phase angle separately, it can be returned so that it may become the same phase as the other louvers 5 by pulling the angle adjustment rope 20 to one side. As for the rotation transmission mechanism, well-known means using a worm wheel and a spring can be used as in Patent Document 1.

Further, it is more preferable that the torsion angle of the buffer member 34 itself has a torsion angle of 360 degrees or more.
This is because, when the louver interval is narrower than the louver width, the louvers 5 arranged at equal intervals usually have an overlapping direction. For example, the left side of the louver is located on the front side of the louver that is located on the left side. The right side is located behind the louver located next to the right side, or vice versa. However, one louver rotates for some reason such as impact or load, and its left and right ends are located on the front side or the back side of the left and right adjacent louvers, which are located on the back side or the front side and overlap each other. Sometimes. If the angle adjusting rope is operated in such a state, the louver itself that is overlapped on the opposite side of the support member that is rotating is overlapped with the adjacent louver in the opposite direction, and therefore cannot be rotated. Further, as described above, the support member has a rotation resistance, but only has a rotation angle of about 180 degrees (90 degrees to the left and right from the specified position), and further rotation is limited.
When correcting louvers that are overlapped in the opposite direction, it is necessary to return them even if they are rotated while holding the louvers by hand. However, if the louver has already been rotated 180 degrees in a state where the rotation of the support member is restricted, the louver may be accidentally rotated 180 degrees in the opposite direction, and a total rotation of 360 degrees is added to the buffer member. Sometimes. The buffer member preferably has a deforming force and a restoring force of 360 degrees or more (about) so that the buffer member may be deformed.

There are various colors on the design surface of the louver 5, but since silicon rubber is excellent in colorability, it can be easily colored in the same color as the louver 5. Therefore, the hanger member 31 including the buffer member 34 can be made substantially the same color as the louver 5, and conversely, the vertical blind 1 can be accented with a color different from the color of the louver 5.
In the present embodiment, since the concave groove 45 for housing the hanger member 31 is formed at the upper end portion of the louver 5, it is possible to prevent a large gap from being formed between the head rail 2 and the upper end of the louver 5.

  In addition, in the lower end part of the louver 5, there is a thing connected so that it may become equal intervals with a bottom cord. For example, the bottom cord plays a role of preventing the rear louver from overlapping the front side of the front louver when the phase of the rear louver changes with respect to the adjacent front louver. In such a state, troubles such as failure to properly store the louver occur. Also in the vertical blind 1 of this embodiment, each louver can be connected with such a bottom cord. However, in this embodiment, when the buffer member is twisted, the rear louver overlaps the front louver. Also, there is an effect of returning by the restoring force of the buffer member using the high tear silicone rubber, and there is also an effect that the bottom cord can be omitted.

  As described above, when a non-elastic louver such as a wooden louver is used as in the present embodiment, when the louver is operated despite an obstacle on the open / close operation line, or the louver When an unexpected load is applied to the louver, such as passing through the louver, the load is applied directly to the louver, hook (support member) or the mechanical part of the carrier, which has been damaged, but the flexibility and reversibility ( By incorporating rubber or synthetic resin members with resilience, it is possible to prevent them from being damaged.

The present invention has been described in detail based on the embodiments with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments, and other modifications can be made without departing from the scope of the present invention. Or it can be changed.
For example, in the said embodiment, although the buffer member 34 of the hanger member 31 was formed in flat plate shape, polygonal pillars, such as a column shape and a square pillar, may be sufficient.
The material of the buffer member has been described as silicon rubber. However, rubber, resin, cloth, metal such as stainless steel or iron to which a thin material is applied and elastic force, and a spring such as a coil spring or a leaf spring can be used.
In addition, the upper and lower connectors 32 and the silicon cushioning member 34 are coupled by gripping the periphery of the circular protrusions 43 and 44 of the cushioning member 34 by the gripping portions 37 and 38. , The hooking piece 35 and the mounting portion of the mounting portion 39 to the buffer member can be formed in a shape suitable for embedding in the resin, and embedded in the silicone rubber when the buffer member is molded. In this case, the hanger member has an integral structure.
Although the upper connector 32 and the lower connector 33 are made of aluminum, other metals such as iron may be used.
