Description

  The present invention relates to a clothes-drying tool that can be stored by folding a frame that supports a plurality of pinches. In particular, the present invention relates to a folding clothesliner.

  Conventionally, as a typical structure of a clothes drying tool that can be made into a compact storage form by folding a frame that supports a plurality of pinches, a so-called folding clothes drying tool can be exemplified.

  In the first place, this foldable clothes dryer has a frame for storing the frame in order to make the foldable clothes dryer compact when storing it when not in use, while securing a large drying area by unfolding the frame of the foldable clothes dryer. It is configured to be folded in a fold. According to the folding direction, according to the folding direction, this folding-type clothes drying tool is a valley fold type that folds upward in the hanging direction on the hanging tool side, and a mountain fold that is folded downward in the hanging direction as in Patent Documents 2 and 4. There is an expression.

In fact, Shozen 57-161988 Japanese Patent Laid-Open No. 11-496 JP 2011-110106 A JP 2004-350712 A

  In the foldable clothes-drying tool as described above, in particular, the ease of installation / storage work of the foldable clothes-drying tool itself is very important, and improvements have been attempted from various directions.

  The items to be improved here are: (i) the foldable clothes dryer itself is small, light and easy to handle, (ii) the folding clothes hangers can be easily suspended and removed, and (iii) the foldable clothes For example, the opening and closing operation of the clothesliner can be performed smoothly.

  However, in any case, the improvement in the complexity of installing and storing the folding clothes-drying tool has not been satisfactory, and has left some problems. It was.

  For example, in Patent Document 1, a typical configuration of the above-described valley folding is disclosed in FIG. 1, but since the frame of the foldable clothes dryer is suspended by a chain, the chain is entangled when the frame is folded. In other words, the folding and unloading operation of the clothesline is hindered.

  Moreover, in patent document 2, although the typical structure of the above-mentioned mountain fold is disclosed by FIG.1, 2, since it is arrange | positioned on the side by which the pinch | pick for clothes drying is folded, FIG. As shown in Fig. 2, pinches are entangled with each other when folded, which causes an obstacle to the opening / closing operation of the folding clothes-drying device as in Patent Document 1.

  In consideration of these points, Patent Document 3 discloses a configuration (FIGS. 1 and 9) that does not use a chain that hinders the frame opening / closing operation. However, in this configuration, the frame suspension portion is located near the center. Therefore, it is necessary to increase the strength of the suspension part, and the structure of the suspension and the suspension part has been increased in size and weight. Furthermore, as shown in FIG. 9 of Patent Document 3, since the hanging part is sandwiched between the frame regions when folded, the suspending / removing work of the foldable clothes drying apparatus is suspended on a suspended member such as a hanging basket. It could not be done in the state, and the work became complicated.

  Furthermore, in Patent Document 4, although the pinch entanglement at the time of folding disappears, the thickness of the frame becomes large enough to store the pinch, which leads to an increase in the weight of the hanger itself. Moreover, in order to align the pinches, the range of rotation of the pinch in the direction of the hanging axis is practically limited, which causes a problem in the pinch attachment operation of the dried food.

  As described above, conventionally, there is no one satisfying all the improvement items (i) to (iii) described above. This is because, among the improvement items described above, there are many trade-off relationships such as the strength and size / weight reduction of the hanger and the workability and operation reliability of the hanger. This is because it is difficult to eliminate these trade-offs. The present invention has been made in view of the above-described conventional drawbacks, and an object of the present invention is to provide a foldable clothes drying apparatus in which the complexity of installing and storing the foldable clothes drying apparatus is generally improved.

  The inventor has intensively studied in view of the above problems, and has arrived at an invention that solves these problems with a completely different technical idea. That is, in order to achieve the above-described object, the clothes-drying tool of the present invention includes a pair of frame members that hold a plurality of pinch members, a hinge portion that rotatably connects a plurality of the pair of frame members, and the pair of frames. A suspension for hanging the frame member, a pair of frame suspension members for suspending the pair of frame members by the suspension by connecting the pair of frame members and the suspension, respectively, and the frame A frame suspension part that rotatably supports and supports the suspension member and the frame member, and a connection support that is provided at the lower end of the suspension tool and that connects and supports the pair of frame suspension members at the connection support part. A pair of frame members opened to each other, and the hinge portion so that the upper ends of the pair of frame members face each other inward. A folding-type clothes-drying device that can be folded, wherein the frame member and the frame suspension member include the frame member at the hinge portion, the frame suspension portion, and the connection support portion. The frame member has a horizontal mechanism in which the frame suspension parts on the same side and the hinge part are aligned in a straight line in the expanded configuration by the function of the link mechanism. The posture is held in a state of being displaced to the position.

  As is clear from the above description, according to the configuration of the present invention, it is possible to eliminate various problems and trade-offs related to the complexity of the installation and storage operations of the folding clothes-drying tool with a very simple configuration. In addition to eliminating various problems that have occurred in the past, it is possible to provide a low-cost and highly reliable clothesline.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

[Explanation about the folding clothesline]
First, the form of the foldable clothes drying tool in which the present invention is suitably used will be described.
FIG. 1 is a perspective view showing the clothes drying tool of the first embodiment of the present invention, and FIG. 2 is a schematic view of the clothes drying tool of the first embodiment of the present invention as viewed from the side.

  In the figure, there are three directions such that the longitudinal direction of the clothesline in the developed form is the X direction, the short direction is the Y direction, and the perpendicular direction to the plane formed by X and Y is the Z direction. FIG. 2 is a schematic diagram viewed from the Y direction. In the following description, when each direction is indicated, only the X, Y, and Z directions are described. FIG. 3 is a partially enlarged schematic view of the clothes drying apparatus according to the first embodiment of the present invention. FIG. 3A is an enlarged schematic view seen from the Y direction, and FIG. 3B is a view seen from the X direction. An enlarged schematic diagram is shown.

  1 to 3, reference numeral 1 denotes a foldable clothes dryer. The foldable clothes dryer 1 holds a plurality of pinch members 9 for hanging laundry and the like, and a hinge portion 7. By connecting the pair of frame members 6a and 6b that are pivotably connected to each other, the suspension member 2 for suspending the frame members 6a and 6b, and the frame members 6a and 6b and the suspension member 2 A frame suspension member 4 for suspending frame members 6a, 6b by the suspension 2, a frame suspension portion 5 for rotatably connecting the frame suspension member 4 and the frame members 6a, 6b, The connecting support member 3 is provided at the lower end portion of the hanger 2 and connects and supports the frame suspension member 4 with the connecting support portion 33.

  As shown in FIG. 1, in this embodiment, the frame members 6 a and 6 b formed of U-shaped metal pipes are connected to each other by a hinge portion 7 so as to be formed in an annular shape such as a substantially rectangular shape. ing. As the outer shape of the frame that forms the outer shape of the folding clothes-drying tool, an oval shape can be taken in addition to such an annular shape. Moreover, resin etc. can also be used as a material of the frame members 6a and 6b.

  As described above, a plurality of pinch members 9 are arranged on the frame members 6a and 6b. However, as the number of pinch members 9 increases, the number of laundry items that can be dried increases. Therefore, in this embodiment, the beam 8 may be provided so as to bridge the long sides including the hinge portion 7 having a substantially rectangular frame outer shape, and the pinch member 9 may be disposed also on the beam 8. . Moreover, although the number of pinch members 9 which can be arrange | positioned increases so that the magnitude | size of the frame members 6a and 6b is large, if the clothes drying tool 1 itself enlarges, a malfunction will arise at the time of accommodation. In view of this, the foldable clothes-drying tool is designed to make the clothes-drying tool compact when stored by folding the pair of frame members 6a and 6b.

  That is, the foldable clothes-drying tool can adopt a deployed form that is a form used as a clothes-drying tool and a storage form that is folded and compact by rotating the frame members 6a and 6b by the hinge portion 7. It is like that.

  In general, with regard to the folding clothes-drying tool, the pair of frame members are folded upward in the hanging direction on the hanging tool side depending on the folding direction (the upper portions where the pinch at the outer end of the frame member is not supported are inward. Folded so as to face each other) (folded so as to be simply called “valley-folded” hereinafter) and folded downward in the hanging direction (folded so that the lower parts where the pinches at the outer ends of the frame members are supported face each other inward) There is a folding type (hereinafter simply referred to as a mountain folding type).

  The foldable clothesliner of the present invention adopts a valley fold type, and since the pinch member 9 is arranged outside the folding direction of the frame members 6a, 6b, a pair of frame members 6a, Since the distance between the pinch members 9 arranged in each of the 6b is increased, the pinch members 9 are not entangled with each other.

  The hanging tool 2 has a hook-like part 10 for hooking the clothes-drying tool on a clothes-drying basket or the like, and a connection support member 3 for connecting and supporting the frame suspension member 4 on the opposite side of the hook-like part 10. Have.

  The frame suspension member 4 is formed of a linear steel material. One end of the frame suspension member 4 is rotated by the frame suspension portion 5 of the frame members 6a and 6b, and the other end is rotated by the connection support portion 33 of the connection support member 3. The frame members 6a and 6b are suspended by the suspension tool 2 via the frame suspension member 4 in the expanded state. The frame suspension member 4 can also be a linear resin material or the like.

  The frame suspension member 4 in the present embodiment is provided corresponding to each of the pair of frame members 6a and 6b, and has an X shape when viewed from the Z direction when deployed. Two frame suspension members 4 may be provided for each frame member 6a, 6b, and the connection support member 3 may be integrated.

  During the storage mode, the suspension member 2 functions to push out the lifting tool 2 from the region of the frame members 6a and 6b in response to the rotation of the frame members 6a and 6b.

  The link mechanism in the present specification refers to the frame suspension member 4, the frame members 6a and 6b, the hinge part 7 that rotatably connects the frame members 6a and 6b, and the frame members 6a and 6b sandwiching the hinge part. This is a mechanism constituted by the frame support part 5 provided on both and the connection support member 3 for connecting and supporting the frame suspension member 4 by a connection support part 33. This link mechanism has a link mechanism with a similar configuration in front and back as viewed from the Y direction (in other words, a link mechanism with a similar configuration is on both sides of the XZ plane including the connection support member 3). When describing the movement of one side of the link mechanism, it is understood that the other side of the link mechanism moves in the same manner. In addition, the link mechanism includes two frame suspension portions 5 on both of the at least two hinge portions 7 and the frame members 6a and 6b. For example, in the deployed form of the folding clothesliner, each frame suspension portion 5 is provided. And the connection support member 3 can take a quadrangular pyramid-like shape with the bottom surface being a surface formed with only the frame suspension portions 5 as vertices.

Next, the main part of the present invention will be described.
In the description of the main part of the present invention, first, the problems inherent in the folding clothes drying tool will be described in detail.

[Detailed explanation about the issue]
As described above, the ease of installation / storage work of the folding clothes-drying tool has been cited as an important issue, and the following improvement items can be cited.
(I) The hanger itself is small, lightweight and easy to handle. This item is typified by the elimination of trade-offs in weight reduction and strength maintenance of folding clothes-drying tools.
(Ii) The folding / drying device can be easily suspended and removed. For example, this item can be suspended and removed as it is in a folded state.
(Iii) The opening / closing operation of the foldable clothes-drying tool is smoothly performed. This item may have a structure in which members such as a pinch and a chain are not easily entangled when folded.

  Of these, the particularly high demand for improvement is the elimination of pinch and chain entanglement.For this reason, in the valley fold type, instead of a chain that is easily entangled, the frame and suspension are integrated, In the mountain fold type, it was found that the frame was made thicker and larger to make it easier to align the pinches, or the distance between the pinches was increased. However, in any configuration, the clothes drying tool itself is large and heavy.

  Moreover, in addition to the trade-off between the strength of the hanger and the reduction in size and weight, other trade-offs such as a trade-off between the workability of the hanger and the operation reliability exist between the above-described problems. Here, as a cause of the trade-off, a large problem inherent in the folding clothesliner has been affected. That is, the conventional folding-type clothes-drying tool has a configuration in which loads during clothes drying are concentrated locally due to its design concept. For example, in the mountain fold type, in order to prevent the frame from rotating and losing its horizontal posture due to the weight of the dried food, the frame hanging portion with a wire or the like is set near the outer edge of the frame, and the frame folding portion (hinge In this design, the load is concentrated on the hinge portion. Further, the valley fold type is basically configured to be hung and held at the frame folding portion (center). This is because when the frame hanging portion is set outside the frame folding portion (center), the frame may be folded into valleys due to the weight of the dried food hung inside the hanging portion. However, even in this design, the load is concentrated on the suspension portion near the hinge portion. And there are some that support the outer edge part with a chain, belt, etc., but because the hanging length is different between the center part and the outer edge part, it is difficult to handle the load evenly. When the posture is inclined, the load is still concentrated on the suspension portion near the hinge portion.

  Although there have been many inventions for load concentration, the approach is an approach such as symptomatic reinforcement and assistance, and as a result, the size and weight of the foldable clothes-drying tool and the rotating operation are reduced. This creates a trade-off related to the ease of installation and storage of the above-described folding clothes-drying equipment, such as sardine.

  Therefore, in any case, the improvement in the complexity of installing and storing the folding clothes-drying tool has not been satisfactory, and has left some problems. It was.

[Explanation regarding characteristic configuration of the present invention]
Next, a configuration that characterizes the present invention will be described.
There are two major features of the present invention. One is the frame suspension member 4, the frame members 6a and 6b, the hinge portion 7, and the frame suspension portion 5 provided on both the frame members 6a and 6b across the hinge portion, and the frame suspension member 4 is connected and supported. This is a link mechanism constituted by the connection support member 3 connected and supported by the portion 33, and the function of this link mechanism enables the posture of the frame members 6a and 6b to be maintained in the deployed form.
The other is a flat posture in which the respective frame suspension members 4 are largely projected outward by using the function of the link mechanism in the unfolded form, and the clothes members in the X direction of the frame members 6a and 6b are arranged. In the central region, the frame members 6a and 6b can be suspended (equally) suspended across the hinge portions 7 of the frame members 6a and 6b.

  In the present invention, these configurations provide a configuration that solves the above-described trade-offs and solves various problems that have occurred in the past with a simple configuration, without adding new members or reinforcing them. It is now possible.

The above-described characteristic configuration will be described in a little more detail.
Since the force acting on the frame suspension member such as a chain and a wire in the conventional folding clothesliner has only been considered as a function as a suspension tool, the frame suspension member in the deployed form is relative to the frame member, In the present invention, the frame members 6a and 6b and the frame suspension member 4 are brought close enough to overlap each other when viewed from the Y direction. The posture of the frame suspension member 4 is set to a state where the frame suspension member 4 is sufficiently laid with respect to the frame members 6a and 6b.

  By adopting this posture, the frame member 6a, 6b is folded by the weight maintained by the posture of the frame members 6a, 6b in the unfolded form, that is, by the weight of the dried article hung between the left and right frame suspensions 5. It is configured to be used as a resistance against the forces that are being attempted.

  In order to realize such an action of the link mechanism, in the present invention, the link mechanism is designed to include an inflection point that changes the direction of the force acting on the frame suspension member 4 during the rotation operation. Before and after the inflection point, the pair of frame members 6a, 6b and the pair of frame suspension members 4 are both convex upward in the suspension direction from a posture that is convex opposite to each other. It becomes the posture to become. And since the attitude | position used as this inflection point is set just before the expansion | deployment form so that the attitude | position of the expansion | deployment form of the frame members 6a and 6b can be maintained, in the expansion | deployment form, the hinge part 7 and the frame suspension part have it. The posture is held by being displaced to a position exceeding the geometric horizontal posture aligned with one another.

  Further, due to this posture, each frame suspension member 4 takes a substantially planar posture such that it protrudes largely outward with respect to the frame members 6a, 6b. The frame members 6a and 6b, which increase the weight burden, are configured to be suspended on a virtual plane connecting the four frame suspensions 5 with respect to the central region of the clothesline in the X direction.

  According to this configuration, it is possible to eliminate the state itself in which the load at the time of hanging clothes that has occurred in the past is concentrated on the local part (part of the suspension part or the hinge part), and there is no need to newly add or reinforce the member. . In other words, it is possible to provide a foldable clothes drying apparatus that is lightweight, easy to handle, and highly reliable with the minimum necessary configuration.

  Hereinafter, the link mechanism as a main part of the present invention and a specific configuration around the link mechanism will be described in detail together with the movement accompanying the rotation of the frame members 6a and 6b.

  FIG. 4 is an operation explanatory view of the connection support member 3 and the frame suspension member 4 in the folding clothes-drying device of the first embodiment of the present invention, and (a) shows an enlarged schematic view seen from the Z direction. (B) has shown the enlarged schematic diagram seen from the Y direction. 5 (a) to 5 (e) show that the frame members 6a and 6b are folded from the storage form in which the frame members 6a and 6b are folded in the folding clothes drying apparatus according to the first embodiment of the present invention. It is operation | movement explanatory drawing which shows a mode that the folding-type clothes-drying tool 1 expand | deploys to the expansion | deployment form fully expanded when it operated.

  First, as described above, the frame members 6a and 6b, the frame suspension member 4 and the suspension tool 2 can be rotated by the hinge portion 7, the frame suspension portion 5 and the connection support portion 33, respectively. The link mechanism is constituted by these.

  Here, in this embodiment, the position of the frame suspending portion 5 is set closer to the center region (close to the hinge portion 7) of the clothesline in the X direction of the frame members 6a and 6b in the unfolded form. The length (the length from the hinge portion 7 of the frame members 6a and 6b to the frame suspension portion 5) L2 is the posture in FIG. 5A (the frame suspension connected from the suspension 2 to the connection support member 3). The positional relationship with the member 4 is that of the frame suspension member 4 in the XZ plane direction in the posture when vertically aligned as in the position pa in FIGS. 3 (a), 3 (b) and 4 (b). It is set slightly longer than the length L1.

The link mechanism exhibits operations and functions as described below.
Fig.5 (a) has shown a mode that the folding-type clothes-drying tool of this embodiment was hung on the hook with the hook-shaped part 10 of the upper part of the hanging tool 2 with the folded storage form. As can be seen from this figure, the foldable clothes-drying tool 1 of the present invention is housed because the hook-like portion 10 of the hanger 2 is displaced from the region sandwiched between the frame members 6a and 6b by the link mechanism to the position protruding. It can be laid in the form as it is. Moreover, as shown in the figure, during the rotation of the frame members 6a and 6b between the storage form and the unfolded form, the tips (outer ends) of the frame members 6a and 6b and the position of the hook-like portion 10 of the hanger 2 are as follows. In order to maintain and displace a state that does not interfere with the hanging direction, the frame members 6a and 6b can be smoothly opened and closed while being hung on the clothesline, resulting in an excellent workability. ing.

  FIGS. 5B to 5E show a state in which the frame 4 is closed (accommodated) (a) to a deployed state by applying force f1 to both ends of the frame members 6a and 6b. (B) is a state in which the frame members 6a and 6b are starting to open, FIG. 5 (c) is a state in which the frame members 6a and 6b are opened and the frame suspension member 4 is horizontal, and FIG. FIG. 5 (e) shows a state in which the frame members 6a and 6b are horizontal, and the frame members 6a and 6b are displaced in an overhanging state to a position exceeding the horizontal posture of the frame members 6a and 6b, and finally developed. Each state is shown as a form. In FIGS. 5B to 5E, the pinch is omitted for easy understanding of the operation of the link mechanism.

  Here, a description will be given focusing on how the link mechanism acts on the frame suspension member 4 during the displacement of FIGS.

  In order to confirm the force acting on the frame suspension member 4, it is easy to understand by following the displacement of the distance between the frame suspension portions 5 arranged on the same side surface (hereinafter simply referred to as the distance between the frame suspension portions). .

  As shown in FIG. 5B, the pair of frame suspension members 4 connected by the connection support member 3 and the pair of frame members 6a and 6b connected by the hinge portion 7 are initially shaped like a rhombus, In this state, the distance w between the frame suspension portions increases as the development progresses.

  After that, as shown in FIG. 5C, after the frame suspension member 4 is in a horizontal state (distance w1 between the frame suspension portions), the distance between the frame suspension portions is as shown in FIG. The frame members 6a and 6b having the maximum value w2 are in a horizontal state.

  Here, as shown in FIG. 5C, when the frame suspension member 4 becomes horizontal, the frame members 6a and 6b still remain bent. This means that the length between the hinge portion 7 and the frame suspension portion 5 of the frame members 6a and 6b is longer than the length of the frame suspension member 4 in the XZ plane direction.

  Therefore, in order to be in the posture of FIG. 5D, it is necessary to extend the frame suspension member 4 by the link mechanism. As shown in FIG. 4, at this time, the frame suspending member 4 is stretched from d1 to d2 in the XZ plane direction, thereby restoring the restoring force (hereinafter referred to as restoring force R1). Is called). Therefore, a force f1 + f2 larger than the aforementioned force f1 is required.

  Further displacement is continued from here, and finally, as shown in FIG. 5 (e), the frame members 6a and 6b are displaced to a position exceeding the horizontal posture and hit a stopper (not shown) of the hinge portion 7. (The distance w3 between the frame suspensions is changed, and the distance w between the frame suspensions is changed from increasing to shortening, and the change in the distance w between the frame suspensions is shown in FIG. ) Means that an inflection point has been reached. At this time, the pair of frame members 6a and 6b and the pair of frame suspension members 4 approach each other so as to overlap with each other when viewed from the Y direction, and both have a posture that is convex upward in the suspension direction.

  The distance w3 between the frame suspension parts is shorter than the distance w2 between the frame suspension parts in the posture of FIG. 5D, and the length in the XZ plane direction of the frame suspension member 4 is also shorter than d2. Since it is d3, the restoring force R1 acting on the above-described frame suspension member 4 is eliminated or considerably reduced. Therefore, when it is going to be folded from the unfolded configuration to the stowed configuration, the restoring force R1 acting on the frame suspension member 4 acts as a resistance against the movement of the frame members 6a, 6b being folded. Therefore, the posture in the deployed form is maintained.

  Moreover, in the foldable clothes drying apparatus of the present invention, in the state where the laundry is hung on the clothes drying apparatus, the weight of the laundry acts on the link mechanism and the posture of the unfolded form becomes more stable.

This will be described with reference to FIG.
FIG. 6 is a conceptual diagram showing the force exerted on the link mechanism by the weight of the laundry being dried in the developed form according to the first embodiment of the present invention.

  In FIG. 6, it is assumed that the laundry is hung from the frame suspension 5 near the hinge 7. This is a state in which the frame members 6a and 6b are most easily reversed from the unfolded form depending on the weight of the laundry.

  When the laundry is suspended from the clothesline 1, a downward force F due to the weight of the laundry is applied to the clothesline 1, and the same force F is applied to the connection support member 3 fixed to the basket. Takes upward. In this way, the pair of frame suspension members 4 and the pair of frame members 6a and 6b constituting the link mechanism are pulled by force F from above and below. At this time, due to the load F, the frame 4 is pressed by the weight F of the laundry so that the hinge portion 7 tends to face downward, so that the lower side of the link mechanism (frame members 6a and 6b) A vector force Fd1 extending in the direction is generated. However, on the other hand, a vector force Fd2 contracting inward is generated on the upper side of the link mechanism (frame suspension members 4 and 4) so as to counteract this vector force Fd1. It is offset by Fd2. That is, the posture in which both the upper and lower sides of the link mechanism in the deployed form are convex upward in the hanging direction is stabilized as it is. If the angle γ sandwiched between the upper side and the lower side of the link mechanism in the figure is 0, the direction of the force received by each member is aligned, so that the posture is further stabilized and the allowable weight of the laundry is maximized. Here, since the allowable weight of the laundry to be hung is reduced as the angle γ is larger than 0, it is desirable that the angle γ in the unfolded form is closer to 0. -The value of γ may not be stable because of play, friction, twisting, distortion, expansion and contraction of the member. Further, for example, when the value of γ is negative, that is, when the position of the connection support member 3 is lower than the position of the hinge portion 7, it does not return or requires a large force when returning to the storage form. Therefore, the position of the connection support member 3 is preferably equal to or greater than the position of the hinge portion 7. Considering these, in the first embodiment of the present invention, the restoring force R1 of the frame suspension member 4 is also used for maintaining the posture as described above. In addition, when the inclination angle θ of the frame members 6a and 6b in the expanded form is greater than or equal to a predetermined value and the angle γ is designed to be close to 0, the system does not use the restoring force R1 of the frame suspension member 4. In addition, the posture of the unfolded form can be maintained by the weight of the clothesliner.

  Then, the position of the frame suspension part 5 which is one of the important elements in the link mechanism as described above will be described.

  Regarding the position of the frame suspension 5, in addition to “the relative relationship with the frame suspension 4 that determines the operation of the link mechanism”, “the suspension balance in the clothesliner for load distribution” and “deployment” It is set in consideration of the “distance between the clothesline and the frame in the form”.

  First, from the viewpoint of “relative relationship with the frame suspension member 4 that determines the operation of the link mechanism”, the distance L2 between the hinge portion 7 and the frame suspension portion 5 and the length of the frame suspension member 4 in the XZ plane direction. It is preferable that the length is not so different from the length L1. This is because, when L2 >> L1, the link mechanism cannot even reach the horizontal posture of the frame members 6a and 6b even with the elastic deformation of the suspension member. When L2 << L1, Since the posture of the frame suspension member 4 stands when deployed, each frame suspension member 4 can not take a substantially planar posture such that each frame suspension member 4 protrudes greatly outward from the frame members 6a, 6b. This is because it is impossible to maintain the deployed form and to disperse it.

  Next, from the viewpoint of “the suspension balance in the clothesliner for load distribution”, from the central region of the clothesliner in the X direction of the frame members 6a and 6b where the weight burden of the clothesline on the clothesline increases, and For example, a position of about 1/3 in the longitudinal direction of the frame is preferable so that the frame suspension portions are appropriately separated from each other and can receive the load of the laundry evenly.

  By doing in this way, it hangs on the virtual surface which connects the four frame suspension parts 5 with respect to the center area | region of the clothesliner of the X direction of the frame members 6a and 6b which the weight burden of the dried goods in a clothesliner becomes large. It is possible to eliminate the state in which the load at the time of hanging clothes that has occurred in the past is concentrated in the local part (part of the suspension part or the hinge part).

Finally, the viewpoint of “distance between the clothesline and the frame in the unfolded form” will be described.
The dimensional relationship of each member in the state of FIG. 5A is “the length of the frame members 6a and 6b in the Z direction = <(L1 + L2) + the linear part length e1 (*) of the lifting device 2”.
It is.
(*) The length of the hanger 2 is a length that allows the entire hook portion 10 to protrude at least outward (upper) in the X direction of the frame members 6a and 6b in the storage configuration of FIG. The straight part length e1 below 10 is a value determined by the design specifications of the hung distance h (FIG. 5 (e)) from the heel to the frame member 6 surface in the unfolded form.

  However, the shortest distance in the setting of the suspension distance h is limited by the length of L2 determined from the position of the frame suspension portion 5.

  As L2 is longer, the suspension distance h is shorter. However, as L2 is longer, the position of the frame suspension portion 5 is set further away from the hinge portion 7 of the frame member 6, and the frame member 6 is closed from the closed storage form. The force applied to both ends of the frame member 6 when expanding is equivalent to a lever, the both ends of the frame member 6 correspond to a force point, the frame suspension portion 5 corresponds to a fulcrum, and the hinge portion 7 corresponds to a point of action. As the power gets heavier, deployment becomes more difficult. When the length of L2 that can be opened practically was measured, it was opened reasonably if it was about 45% or less from the center of the length in the X direction of the frame members 6a and 6b. On the contrary, the shorter L2 is taken, the less force is required when unfolding the frame 4, but this time it is necessary to lengthen the length of the suspension 2 and the suspension distance h becomes longer. There is a relationship. If the hanging distance h is set too long, it will be easier for the laundry to touch the floor where the vertical space is not as large as the apartment veranda when the laundry is dried. .

When the maximum value of the frame members 6a and 6b that can be taken by L2 is set to 45% from the center of the length in the X direction, the length of the straight portion of the suspension 2 is e1 when the length of the frame members 6a and 6b is 100%. The length is "100%-(45% + about 45%) ≒ 10%"
That is, “e1 ≒ frame member 6a, 6b length / 10”
The hung distance h is as short as about 10% of the length of the frame members 6a and 6b and can be extremely short. This is equivalent to or shorter than the conventional structure of the similar configuration in which the frame members 6a and 6b are held by the frame suspension member 4, and the clothesline 1 has one of desirable characteristics.

  Below, the actual measurement data in the clothes drying tool 1 of FIG. 1 made in consideration of the above-mentioned elements are shown. The following specifications are prototyped as a movable demonstration model of the present invention, and the technical scope of the present invention is not limited to this specification.

[Dimensions of each part]
-Length in the X direction of the frame members 6a, 6b = 420mm
-Length in the Y direction of the frame members 6a and 6b = 350 mm
・ Hanging distance h = 190mm
・ L2 length of frame members 6a and 6b = 160 mm
・ L1 length of frame suspension member 4 = 150 mm
・ Inclination θ of frame members 6a and 6b = 6 degrees ・ f1 + f2 <250 g
[Laundry weight limit]
-When the load resistance when the four innermost pinch positions 60 mm from the hinges 7 of the frame members 6a and 6b were pulled downward simultaneously with the tension gauge was measured, the frame 4 was It did not fold downward. A load test of 10 kg or more may cause damage to the prototype, and no further tests were performed. It can be said that the load-bearing performance of 10 kg or more for only some of the pinches is a value that is more than enough for practical use.

  As described above, in order to avoid folding in the valley fold of the prior art, a suspension was provided at the hinge portion position, but in the configuration of the present invention, strong against the force F to be folded. Power is provided and it does not fold easily.

  In addition, a locking mechanism (not shown) such as an unevenness is provided around the hinge portion 7 so that the posture in which the frame members 6a and 6b in the state diagram 5a of FIG. You may keep it.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the present embodiment, the first configuration is such that the posture of the deployed configuration can be maintained in a horizontal posture where the pair of frame members are in a straight line during the deployed configuration (at the time of maximum deployment). This is different from the embodiment.
This will be described below with reference to the drawings.

FIG. 7 is a schematic view showing a developed form of the clothes drying tool of the second embodiment of the present invention, and FIG. 8 is an explanatory view showing a link mechanism in the clothes drying tool of FIG.
First, even in this embodiment, the frame members 62a and 62b, the frame suspension member 42, and the suspension tool 22 are respectively the hinge portion 72, the frame suspension portion 52, and the connection support portion 332. It is connected and supported so as to be rotatable, and these constitute a link mechanism.

  With regard to the displacement of the link mechanism, the same behavior as that of the first embodiment is exhibited, and after the geometrical horizontal posture in which the hinge portion 72 and the frame suspension portion 52 are aligned, they are expanded. In the form, the posture is held by being displaced to a position exceeding the geometric horizontal posture.

  However, in the present embodiment, in a horizontal posture in which the pair of frame members 62a and 62b are in a straight line, the hinge portion 72 and the pair of frame suspension members 42 are displaced to a position exceeding the geometric horizontal posture. Since it is necessary, the configuration of the first embodiment based on the premise that the frame members 62a and 62b are overhanged in the expanded form cannot be handled as it is.

  Therefore, in this embodiment, both or one of the hinge portion 72 and the pair of frame suspension portions 52 is used as an axis (frame) in the extending direction of the frame members 62a and 62b so that the link mechanism is displaced. The center of the member in the width direction) is provided so as to be deviated in the vertical direction, and each of the deviating direction or the amount of deviation is made different so that the link mechanism similar to that of the first embodiment can be obtained. Displacement and behavior are realized.

  As a configuration in which the hinge portion 72 and the pair of frame suspension portions 52 are displaced in the vertical direction of the frame members 62a and 62b, the hinge portion 72 is a portion that protrudes vertically upward (to the lifting tool side) with respect to the frame. May be provided, and the displacement from the frame members 62a and 62b may be realized, or the frame suspension 52 is provided with a portion protruding downward in the vertical direction with respect to the frame. Deviation from the frame members 62a and 62b may be realized by forming the frame suspension 52. Of course, any of the above can be used together. In addition, when the vertical width of the frame members 62a and 62b is sufficiently large, the hinge portion 72 and the pair of frame suspension portions 52 can be connected to the frame members 62a and 62b within the range of the frame width without providing the protrusions. It is also possible to deviate in the vertical direction.

  7 and 8, the hinge portion 72 is provided on the frame support member 712 that connects the pair of frame members 62a and 62b, and the position thereof is slightly shifted upward in the vertical direction from the axis of the frame members 62a and 62b. In addition, the frame suspension portion 52 is formed by the suspension portion support member 512 attached to the frame members 62a and 62b to form the above-described protruding portion, vertically below the frame members 62a and 62b, and inside the frame. The structure which provides the frame suspension part 52 in is disclosed.

  If the pair of frame members 62a and 62b in the deployed state are positioned between the hinge portion 72 and the pair of frame suspension portions 52 that are offset with respect to the vertical direction, where It may be arranged, and is a range indicated by an arrow m in FIG. The upper limit is arranged on the same axis as the hinge part 72, and the lower limit is arranged on the same axis as between the pair of frame suspension parts 52.

Next, the operation and function of the link mechanism of this embodiment will be described with reference to FIG.
FIGS. 9A to 9E show a state from the closed state of the frame members 62a and 62b to the expanded form of the frame members 62a and 62b. FIG. 9A is a clothesline according to this embodiment. FIG. 9B shows a state in which the frame members 62a and 62b have begun to open, FIG. 9C shows a state in which the frame members 62a and 62b are opened and the frame is suspended. 9 (d) shows a state in which the member 42 is horizontal, FIG. 9 (d) shows a state in which the hinge portion 72 and the frame suspension portion 52 are aligned, and FIG. 9 (e) shows a state in which the hinge portion 72 and the frame suspension portion 52 are arranged. Are displaced to a position exceeding the geometrical horizontal posture arranged in a straight line, and the pair of frame members 62a and 62b are in a final developed form in which they are horizontal and straight.

  9A to 9C are basically the same as the situation of the first embodiment (FIGS. 5A to 5C).

  In this embodiment, in the state of FIG. 9D in which the hinge portion 72 and the frame suspension portion 52 are in the geometric horizontal posture of the link mechanism aligned in a straight line, the hinge portion 72 and the pair of frame suspensions are provided. The portion 52 is provided so as to be deviated in a direction perpendicular to the extending axis of the frame members 62a and 62b, so that the pair of frame members 62a and 62b are still bent upwardly and shallowly. Yes.

  Thereafter, the pair of frame members 62a and 62b are further opened to reach a position exceeding the geometric horizontal posture in which the hinge portion 72 and the frame suspension portion 52 are aligned as shown in FIG. 9 (e). The pair of frame members 62a and 62b are displaced and become a final developed form in which they are horizontal and straight. At this time, the link mechanism is designed to include an inflection point that changes the direction of the force acting on the frame suspension member 42 in the middle of the rotation operation. When attempting to fold, the restoring force acting on the frame suspension member 42 acts as a resistance against the movement of the frame members 62a and 62b to be folded, and the posture in the deployed form is maintained. Is.

Thus, regarding the displacement / behavior of the link mechanism, the same movement and action as in the first embodiment are shown.
However, in the first embodiment, the frame member itself moves by tracing the behavior of one of the geometric link mechanisms (the component connecting the frame suspension portion 5 and the hinge portion 7). Then, a component that connects a part of the frame suspension part 52 and the hinge part 72 and the frame members 62a and 62b intersect with each other at a predetermined inclination angle, so when only the frame members 62a and 62b are viewed, The displacement behavior is different from that of the first embodiment.

  Therefore, even in the operation of the link mechanism, in the present embodiment, the frame suspension member 42 constituting the link mechanism and the virtual line V (see FIG. 8) connecting the frame suspension portion 52 and the hinge portion 72 are viewed. When viewed, both of them are convex upward in the suspending direction from the postures that are convex so as to face each other during the rotation operation associated with the deployment / storage configuration of the frame members 62a, 62b.

  In the present embodiment, before and after the inflection point, the pair of frame suspension members 42 and the imaginary lines V connecting the pair of frame suspension portions 52 and the hinge portions 72 are convex to face each other. From these postures, both become convex upward in the hanging direction.

Next, the structure around the frame suspension member 42 in this embodiment will be described in detail.
10 to 12 are perspective views showing this embodiment, FIG. 11 is a side view of FIG. 10, and FIG. 12 is a partial cross section near the frame suspension 52 along the line aa ′ of FIG. 11. It is an enlarged schematic diagram.

  As shown in FIG. 10, a beam 82 for suspending the pinch member is provided between the frame suspending portion 52 and the hinge portion 72. In addition, pipe-shaped members are used as the frame members 62a and 62b. The member connected to the hinge portion 72 and the suspension portion support member 512 provided with the frame suspension portion 52 are the frame members 62a and 62b. The frame suspension portion 52 is formed at a portion projecting inward from the lower side of the frame member, and the frame suspension portion 52 is formed on the frame members 62a and 62b. On the other hand, it is configured to slightly deviate downward (see FIG. 12).

  Thus, in the configuration in which the beam 82 is provided between the frame suspension portion 52 and the hinge portion 72, the frame suspension portion 52 is displaced below the frame members 62a and 62b as in this embodiment. In this case, in the developed form, the frame member 62a and the frame suspension member 42 partially cross each other, so that the beam 82 and the frame suspension member 42 approach each other and easily interfere with each other. In that case, as shown in FIG. 13, a part of the beam 83 can be cut out to prevent the beam 83 and the frame suspension member 42 from interfering with each other. Further, it is possible to prevent the beam 82 and the frame suspension member 43 from interfering with each other by bending the frame suspension member 43 as shown in FIG.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
In the present embodiment, the point that the stop portion 101 that restricts the rotation of the frame suspension member 41 in the unfolding direction is provided near the connection support portion of the connection support member is mainly different from the first embodiment. It has become.

This will be described below with reference to the drawings.
FIG. 15 is a schematic view when the clothes-drying tool of the third embodiment of the present invention is viewed from the side, FIG. 16 is an enlarged schematic view showing the main part of FIG. 15, and FIGS. 15 is an enlarged schematic view showing the vicinity of the connection support member 15 and an operation explanatory view of the connection support member 31 and the frame suspension member 41. FIG. 19 shows the frame in the clothes drying apparatus according to the third embodiment of the present invention. It is operation | movement explanatory drawing which shows a mode that it does.

  In the present embodiment, as shown in the figure, a restraining portion 101 formed by projecting a part of the connection support member 31 obliquely downward in the hanging direction is provided in the vicinity of the connection support portion 331 of the connection support member 31. . The restraining portion 101 abuts on the frame suspension member 41 before reaching the deployed configuration in the pivoting operation of the frame member, and regulates the rotation in the deployed direction. The posture of the frame members 61a and 61b can be held in a posture in which the posture of 41 is raised somewhat from substantially horizontal.

  And by setting it as such a structure, the deformation | transformation by the weight at the time of the laundry hanging in the deployment form, and the elastic deformation of the frame member, the frame suspension part, the frame suspension member 41, etc. by external force by wind etc. It is possible to prevent the release of posture maintenance in an unintended deployment form caused by deformation wear due to aging or aging.

  This means that a sufficient design margin can be taken with respect to maintaining the posture of the link mechanism in the deployed form, which leads to an improvement in the yield of clothes drying equipment manufacturing.

  In the present embodiment, the restraining portion 101 is shown as being integrally formed with the connection support portion 31, but it may be configured such that the protruding amount of the connection support portion 31 can be adjusted with a screw or the like. Is.

The function of the stop part of this embodiment will be described in detail with reference to FIG.
First, in this embodiment, since two hinge portions 71 are formed side by side in the X direction, the frame members 61a and 61b have a slight distance between the lower ends when the frame members 61a and 61b are closed. However, regarding the basic behavior of the link mechanism, it can be seen that the behavior is almost the same as that of the first embodiment.

  In FIG. 19, the point that differs greatly from the situation of the first embodiment (FIG. 5) is the time of FIG. 19C, and this changes the force applied to the frame suspension member 41 in the subsequent steps. It is coming.

  Details of the force applied to the frame suspension member 41 are shown in FIGS. 17 and 18, and p1a, p1b, and p1c in FIGS. 17 and 18 are respectively shown in FIGS. 19 (c), 19 (d), and (e). The posture of the frame suspension member 41 in FIG.

  FIG. 19C shows a state in which the frame suspension member 41 is in contact with the restraining portion of the connection support member.

  In FIG. 19 (c), the frame suspension member 41 quickly contacts the restraining portion 101 by the angle β, so that the force f11 applied to both ends of the frame members 61a and 61b before the frame suspension member 41 is aligned horizontally. The movement stops, and further force f21 needs to be applied to open it.

  Although the length of the frame suspension member 41 is d11 at the position p1b, it reaches the state (d) from the state (c) of FIG. 19 as the frame members 61a and 61b are further opened, and the length d11 is extended to d21. . At this time, as in the first embodiment, the frame suspension member 41 generates a restoring force R1 due to elasticity.

  When the frame member is further rotated, since the rotation of the frame suspension member 41 in the Y-axis direction is restricted by the restraining portion 101, the frame suspension member 41 is positioned at the position p1c as shown in FIG. The distance d41 is warped in the rotational direction, and the state shown by the symbol s in FIG. 19D is obtained, and a restoring force R2 due to elasticity is generated in the frame suspension member 41.

  The restoring forces R1 and R2 are only R1 in the first embodiment. However, in this embodiment, the restoring force R2 by the restraining portion 101 is further applied. Therefore, the force fα1 for pressing both ends of the frame 61 in the state of FIG. Therefore, it becomes stronger than the first embodiment.

Thus, it will be understood that the restoring force R2 has the effect of reinforcing the decrease in the vector force Fd2 by setting the angle of the frame suspension member 41 in the deployed form to be higher than the horizontal. About this angle, it can set arbitrarily by adjusting the protrusion amount from the connection support member 31 of the stop part 101 as needed. However, when this angle is extremely increased, the load bearing performance is reduced to the conventional level, which is not preferable.

  The present invention is used in industries that use and manufacture clothes drying equipment.
