Description

  The present invention relates to a clothesline that can be stored by folding a frame that supports a plurality of pinches. In particular, it relates to a folding clothesline.

  2. Description of the Related Art Conventionally, as a typical configuration of a clothesline that can be compactly stored by folding a frame that supports a plurality of pinches, there is a typical structure that is generally referred to as a foldable clothesline.

  In the first place, this folding clothesline is designed to have a large clothes-drying area by unfolding the frame of the folding clothespan at the time of drying, and to compactly store the folding clothespan when not in use. It is configured to be folded in half. Depending on the folding direction, this folding type clothes dryer has a valley fold type that folds upward in the hanging direction on the hanging tool side as in Patent Documents 1 and 3, and a mountain fold that folds downward in the hanging direction as in Patent Documents 2 and 4. There is a formula.

  In the above-mentioned foldable clothes dryer, the ease of installation and storage of the foldable clothes dryer itself is very important, and improvements have been attempted from various directions in the past.

  The items to be improved here are (i) that the foldable clothes dryer itself is small, light and easy to handle, (ii) that the foldable clothes dryer can be easily suspended and removed, and (iii) that the foldable clothes dryer can be easily folded and removed. That the opening and closing operation of the clothesline is performed smoothly, and the like.

  However, in any case, the improvement in the complexity of the installation and storage of the folding clothesline has not been satisfactory, and some problems have been left. Was.

  For example, in Patent Literature 1, a typical configuration of the above-described valley folding is disclosed in FIG. 1, but since the frame of the folding clothesline is hung by a chain, the chain is entangled when the frame is folded. As a result, the opening / closing operation of the folding clothesline is hindered.

  In addition, in Patent Document 2, a typical configuration of the above-described mountain folding is disclosed in FIGS. 1 and 2. However, since a pinch for drying clothes is disposed on the side to be folded, FIG. Since the pinches are entangled at the time of folding as shown in FIG. 1, the opening / closing operation of the folding clothesline is hindered as in Patent Document 1.

  Patent Document 3 discloses a configuration (FIGS. 1 and 9) that does not use a chain that hinders the frame opening / closing operation in consideration of the above. In this configuration, the hanging portion of the frame is positioned near the center. Therefore, it is necessary to increase the strength of the hanging portion, and the configuration of the hanging tool and the hanging portion has been increased in size and weight. Further, as shown in FIG. 9 of Patent Document 3, since the hanging part is sandwiched in the frame area when folded, the work of suspending / removing the folding clothesline is suspended on a suspended member such as a clothesline. Work could not be carried out in a state where it was left out.

  Further, in Patent Document 4, although the tangling of the pinch at the time of folding is eliminated, the thickness of the frame becomes large enough to accommodate the pinch, which leads to 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 operation of attaching the pinch to the dried product.

  As described above, conventionally, there is no one that satisfies all of the above improvement items (i) to (iii). Because, among the above-mentioned improvements, there are many trade-offs such as, for example, the strength and the size and 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. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional drawbacks, and has as its object to provide a folding clothes dryer in which the complexity of installation and storage operations of the clothes dryer is generally improved.

  The present inventor has made intensive studies in view of the above problems, and as a result, has arrived at an invention that solves these problems with a technical idea completely different from that of the related art. That is, in order to achieve the above object, a clothesline 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 a pair of the pair of frame members. A hanging member for suspending the frame member, a pair of frame hanging members for hanging the pair of frame members by the hanging member by respectively connecting the pair of frame members and the hanging member, and the frame A frame suspending portion for rotatably connecting and supporting a suspending member and the frame member, and a connecting support provided at a lower end portion of the suspending tool for connecting and supporting the pair of frame suspending members by a connecting support portion. And a deployment form in which the pair of frame members are open, and the hinge portion so that upper ends of outer ends of the pair of frame members face inward. A folded clothes dryer that can take a folded storage form, wherein the frame member and the frame suspending member include the frame member at the hinge portion, the frame suspending portion, and the connection support portion. The frame member is moved beyond the horizontal posture in which the frame hanging portions and the hinge portions on the same side face are aligned in the unfolded form by the action of the link mechanism. It is characterized in that the posture is held while being displaced to the position.

  As is clear from the above description, according to the configuration of the present invention, with a very simple configuration, the installation of the folding clothesline, various problems and trade-offs related to the complexity of the storage operation can be eliminated, The present invention not only eliminates various inconveniences that have conventionally occurred, but also enables a low-cost and highly reliable clothesline.

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

  In the figure, three directions are set such that the longitudinal direction of the clothesline in the unfolded form is the X direction, the short direction is the Y direction, and the direction perpendicular 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 indicating each direction, only the X, Y, and Z directions are described. FIGS. 3A and 3B are partially enlarged schematic views of the clothesline according to the first embodiment of the present invention, wherein FIG. 3A is an enlarged schematic view as viewed from a Y direction, and FIG. FIG.

  1 to 3, reference numeral 1 denotes a foldable clothesline. The foldable clothesline 1 holds a plurality of pinch members 9 for hanging laundry and the like, and holds the plurality of pinch members 9. The pair of frame members 6a, 6b rotatably connected by the above, the hanging member 2 for hanging the frame members 6a, 6b, and the frame members 6a, 6b and the hanging member 2 are connected to each other. A frame hanging member 4 for hanging the frame members 6a and 6b by the hanging member 2, a frame hanging portion 5 for rotatably connecting the frame hanging member 4 and the frame members 6a and 6b, And a connection support member 3 provided at a lower end of the hanging member 2 and connecting and supporting the frame hanging member 4 with a connection support portion 33.

  As shown in FIG. 1, in the present embodiment, the frame members 6 a and 6 b formed by U-shaped metal pipes are connected to each other by hinges 7 to form a substantially rectangular ring shape. ing. The outer shape of the frame that forms the outer shape of the folding clothesline can take an oval shape in addition to such an angular ring. Further, a resin or the like can be used as a material of the frame members 6a and 6b.

  Although a plurality of pinch members 9 are arranged on the frame members 6a and 6b as described above, as the number of the pinch members 9 increases, the number of laundry items that can be dried increases. For this reason, in the present embodiment, the beam 8 may be provided so as to bridge the long sides including the hinge portion 7 of the substantially rectangular frame outer shape, and the pinch member 9 may be arranged on the beam 8 as well. . The number of pinch members 9 that can be arranged increases as the size of the frame members 6a and 6b increases. However, if the clothes rack 1 itself becomes large, a problem occurs during storage. In view of this, the foldable clothesline is designed to be compact when stored by folding the pair of frame members 6a and 6b.

  In other words, the folding clothes-drying tool can adopt an unfolded form, which is a form used as a clothes-drying tool, and a storage form, which is folded and compact, by the pivotal movement of the frame members 6a, 6b by the hinge portion 7. It has become.

  In general, for a folding clothesline, depending on the folding direction, a pair of frame members are folded upward in the hanging direction on the hanging member side (upper portions at the outer ends of the frame members where the pinch is not supported are inward. A valley fold type (hereinafter simply referred to as a valley fold type) and a mountain that folds downward in the hanging direction (folds so that lower portions of the outer end of the frame member where the pinch is supported are facing inward) There is a folding type (hereinafter, simply referred to as a mountain folding type).

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

  The hanging tool 2 has a hook-shaped part 10 for hooking the clothes-line on a clothesline or the like, and a connecting support member 3 for connecting and supporting the frame hanging member 4 on the opposite side to the hook-shaped part 10. Have.

  The frame suspension member 4 is formed of a linear steel material, and one end 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 hung by the hanger 2 via the frame hanger member 4 in the unfolded configuration. Further, the frame suspension member 4 may be made of a linear resin material or the like.

  The frame hanging members 4 in the present embodiment are provided corresponding to the pair of frame members 6a and 6b, respectively, and have an X-shape when viewed from the Z direction in the unfolded state. Two frame hanging members 4 may be provided for each of the frame members 6a and 6b, and the frame supporting members 4 may be integrated with each other.

  In the storage state, the hanging member 2 functions so as to be pushed out of 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 specification of the present application includes the frame suspension member 4, the frame members 6a and 6b, the hinge portion 7 that rotatably connects the frame members 6a and 6b, and the frame members 6a and 6b with the hinge portion interposed therebetween. This is a mechanism composed of a frame suspension unit 5 provided on both sides and the connection support member 3 for connecting and supporting the frame suspension member 4 by a connection support unit 33. When viewed from the Y direction, this link mechanism has a link mechanism of the same configuration at the front and the back (in other words, the link mechanisms of the same configuration are on both sides of the XZ plane including the connection support member 3). When describing the movement of one link mechanism, it is understood that the other link mechanism performs the same movement. In addition, the link mechanism includes at least two hinge portions 7 and two frame hanging portions 5 on both of the frame members 6a and 6b. For example, in the unfolding mode of the folding clothesline, each frame hanging portion 5 is provided. And the connecting support member 3 can take the shape of a quadrangular pyramid whose bottom is a surface formed with only each of the frame hanging portions 5 as a vertex.

Next, the main part of the present invention will be described.
In describing the main parts of the present invention, first, the problems inherent in the folding clothesline will be described in detail.

[Detailed description of issues]
As described above, the ease of installation and storage of the foldable clothes rack 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 typically represents a trade-off between weight reduction and strength maintenance of the folding clothesline.
(Ii) The folding clothesline can be easily suspended and removed. This item may be, for example, suspended or removed in a folded state.
(Iii) The opening and closing operation of the foldable clothesline is performed smoothly. This item may be configured such that members such as a pinch and a chain are hardly entangled when folded.

  Among them, the issue of high demand for improvement is the elimination of pinch and chain entanglement.For this reason, in the valley fold type, instead of the chain that is easily entangled, the frame and the suspension are integrated, In the mountain-folding type, a configuration was found in which the frame was made thicker and larger to make it easier to align the pinches, and the distance between the pinches was increased. However, in any of the configurations, the clothes dryer itself becomes large and heavy.

  Moreover, in addition to the trade-off between the strength and the size and weight reduction of the hanger, there are other trade-offs between the above-mentioned problems, such as the trade-off between the workability and the operation reliability of the hanger. Here, as a cause of the trade-off, a large problem inherent in the folding clothesline has conventionally been influenced. That is, the conventional folding clothesline has a configuration in which the load at the time of the clothesline is concentrated on a local portion from the design concept. For example, in the mountain-folding type, in order to prevent the frame from rotating and disturbing the horizontal posture due to the weight of the dried items, the frame hanging portion with a wire or the like is set near the outer end of the frame, and the frame folded portion (hinge) is used. Although the frame deployment posture is maintained using the rotation restricting force of the part (2), the load concentrates on the hinge portion in this design. Further, in the valley folding type, basically, it is configured to be hung and held at the frame folded portion (center). This is because, when the frame hanging portion is set outside the frame turning portion (center), there is a possibility that the frame may be folded in a valley due to the weight of the dried product hung inside the hanging portion. However, even in this design, the load concentrates on the suspension near the hinge. And there are some that support the outer edge part with a chain or a belt, etc., but it is difficult to bear the load evenly because the hanging length is different between the central part and the outer edge part. When the posture is inclined, the load is still concentrated on the hanging portion near the hinge portion.

  Although various inventions have been made for load concentration, the approach is an approach such as reinforcement or assistance for symptomatic treatment, and as a result, the folding clothesline becomes large and heavy, and the folding operation is performed. This creates a trade-off, such as difficulty, related to the ease of installation and storage of the above-mentioned folding clothesline.

  Therefore, in any case, the improvement in the complexity of installing and storing the foldable clothes rack has not been satisfactory, and some problems have been left. Was.

[Description of Characteristic Configuration of the Present Invention]
Next, a characteristic configuration of the present invention will be described.
There are two main features of the present invention. One is to connect and support the frame hanging member 4, the frame members 6a and 6b, the hinge portion 7, and the frame hanging portions 5 and the frame hanging members 4 provided on both of the frame members 6a and 6b with the hinge portion interposed therebetween. This is a link mechanism constituted by the connection support member 3 connected and supported by the portion 33. The function of the link mechanism enables the frame members 6a and 6b to maintain their posture in the deployed form.
The other is to use the function of the link mechanism to set each of the frame hanging members 4 in a flat posture so as to protrude largely outward, and to use the clothes members in the X direction of the frame members 6a and 6b in the unfolded form. That is, in the central region, the frame members 6a and 6b can be dispersed (equally) suspended across the hinge portions 7 of the frame members 6a and 6b.

  In the present invention, with these configurations, there is provided a configuration that solves the above-mentioned trade-offs and solves various problems that have conventionally occurred at a stretch with a simple configuration without adding or reinforcing new members. It is now possible.

The above-mentioned characteristic configuration will be described in more detail.
The force acting on the frame hanging member such as a chain or a wire in the conventional folding clothesline has been considered only as a function of the hanging member, so the frame hanging member in the unfolded form is relative to the frame member, In the present invention, the frame members 6a and 6b and the frame hanging member 4 are brought close to each other so as to overlap with each other when viewed from the Y direction. The posture of the frame hanging member 4 is set to be in a state of being sufficiently laid on the frame members 6a and 6b.

  By adopting this attitude, the force generated by the link mechanism is maintained in the deployed state of the frame members 6a and 6b, that is, the frame members 6a and 6b are folded by the weight of the dried clothes hung between the left and right frame hanging portions 5. It is designed to be used as a drag against the force that is going to be applied.

  In order to realize such an operation of the link mechanism, the present invention is designed so that the link mechanism includes an inflection point that changes the direction of the force acting on the frame suspension member 4 during the turning operation. Note that before and after this inflection point, the pair of frame members 6a and 6b and the pair of frame hanging members 4 are convexly opposed to each other. Posture. The inflection point is set immediately before the unfolded state so that the unfolded state of the frame members 6a and 6b can be maintained. The posture is maintained by displacing to a position exceeding the geometrical horizontal posture aligned in a straight line.

  Further, by this posture, each of the frame hanging members 4 takes a substantially planar posture such that they protrude largely outward from the frame members 6a and 6b. The structure is such that the frame members 6a and 6b, which are heavy in weight, are suspended on the virtual plane connecting the four frame suspension portions 5 to the central region of the clothesline in the X direction.

  According to this configuration, it is possible to eliminate the state in which the load at the time of drying, which has conventionally occurred, is concentrated on a local portion (a part of the hanging portion or the hinge portion), and it is not necessary to newly add or reinforce a member. . In other words, it is possible to provide a lightweight, easy-to-manage and highly reliable foldable clothesline with a minimum necessary configuration.

  Hereinafter, such a 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 pivotal movement of the frame members 6a and 6b.

  FIGS. 4A and 4B are explanatory views of the operation of the connection support member 3 and the frame suspension member 4 in the folding clothesline of the first embodiment of the present invention, and FIG. 4A is an enlarged schematic diagram viewed from the Z direction. (B) is an enlarged schematic diagram viewed from the Y direction. FIGS. 5 (a) to 5 (e) show the folding clothes dryer according to the first embodiment of the present invention, in which the frame members 6a, 6b are folded from the storage state in which the frame members 6a, 6b are folded. It is operation | movement explanatory drawing which shows a mode that the foldable clothesline 1 expand | deploys to the expansion | deployment form which expanded completely when operated.

  First, as described above, the frame members 6a, 6b, the frame hanging member 4, and the hanging member 2 can be rotated by the hinge portion 7, the frame hanging portion 5, and the connection support portion 33, respectively. And a link mechanism.

  Here, in the present embodiment, the position of the frame hanging portion 5 is set closer to the center region (closer to the hinge portion 7) of the clothes dryer 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 hanging portion 5) L2 is the posture (the frame hanging connected from the hanging member 2 to the connecting support member 3) in FIG. The positional relationship with the member 4 is determined by the position of the frame hanging member 4 in the XZ plane direction at the time of vertical alignment like the position pa in FIGS. 3 (a), 3 (b) and 4 (b). The length is set slightly longer than the length L1.

The link mechanism exhibits the operation and function as described below.
FIG. 5A shows a state in which the foldable clothesline of the present embodiment is hung on a rod by the hook-shaped portion 10 above the hanging member 2 in the folded storage state. As can be seen from this figure, the folding clothesline 1 according to the present invention is displaced to a position where the hook-like portion 10 of the hanging member 2 protrudes from the region sandwiched between the frame members 6a and 6b by the link mechanism. It can be hung on a pole as it is. Moreover, as shown in the drawing, during the pivoting operation of the frame members 6a, 6b between the storage mode and the unfolded mode, the positions of the tips (outer ends) of the frame members 6a, 6b and the hook-shaped portions 10 of the hanging members 2 are different. In order to maintain the state in which it does not interfere with the hanging direction and to displace, the frame members 6a and 6b can be smoothly opened and closed while being hung on the clothesline, and a configuration excellent in workability is obtained. ing.

  FIGS. 5B to 5E show a state in which the frame 4 is in a closed state (storage mode) (a) to a deployed mode by applying a force f1 to both ends of the frame members 6a and 6b. 5B shows a state in which the frame members 6a and 6b have begun to open, FIG. 5C shows a state in which the frame members 6a and 6b have opened and the frame hanging member 4 has become horizontal, and FIG. The state in which the frame members 6a and 6b are horizontal, FIG. 5E shows that the frame members 6a and 6b are displaced in an overhang shape to a position beyond the horizontal posture of the frame members 6a and 6b, and the final deployment Each state is shown. In FIGS. 5B to 5E, the pinch is omitted for easy understanding of the operation of the link mechanism.

  Here, how the link mechanism acts on the frame suspending member 4 during the displacement of FIGS. 5B to 5E will be described.

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

  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 6 a and 6 b connected by the hinge 7 initially have a diamond shape. In this state, the distances w between the frame hanging portions are increased as the deployment progresses.

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

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

  Therefore, in order to attain 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 has its length in the XZ plane increased from d1 to d2, and thereby has a restoring force of returning to the original state (hereinafter, this restoring force is referred to as restoring force R1). Work). Therefore, a force f1 + f2 larger than the above-mentioned force f1 is required.

  The displacement is further continued from here, and finally, as shown in FIG. 5 (e), the frame members 6 a and 6 b are displaced to positions beyond the horizontal posture, and the frame members 6 a and 6 b hit a stopper (not shown) of the hinge 7. (A distance w3 between the frame hanging portions, the distance w between the frame hanging portions is changed from an increase to a shortening, and the change in the distance w between the frame hanging portions is shown in FIG. This means that the inflection point has been reached at the point of). At this time, the pair of frame members 6a and 6b and the pair of frame suspending members 4 approach each other so as to be further overlapped when viewed from the Y direction, and each of them has a posture in which it is convex upward in the suspending direction.

  As for the distance w3 between the frame hanging parts, the distance between the frame hanging parts in the posture of FIG. 5D is shorter than w2, and the length of the frame hanging member 4 in the XZ plane 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 trying to fold from the unfolded form to the stored form, the restoring force R1 acting on the frame hanging member 4 acts as a drag against the movement of the frame members 6a and 6b to be folded. Therefore, the posture in the deployed form is maintained.

  In addition, in the folding clothes-drying device of the present invention, when the clothes are hung on the clothes-drying device, the weight of the laundry acts on the link mechanism, and the deployed posture is more stable.

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

  In FIG. 6, it is assumed that the laundry is hung from the frame hanging portion 5 near the hinge portion 7. This is a state in which the frame members 6a and 6b are most likely to be inverted from the unfolded form due to the weight of the laundry.

  When the laundry is hung on the clothesline 1, a downward force F due to the weight of the laundry is applied to the clothesline 1, and the same drag force F is applied to the connecting support member 3 fixed to the rod. Hang upward. As described above, the pair of frame hanging members 4 and the pair of frame members 6a and 6b constituting the link mechanism are pulled by the force F from above and below. At this time, due to the load F, a force is applied to the frame 4 by the weight F of the laundry so that the hinge portion 7 is directed downward, so that the lower side of the link mechanism (the frame members 6a and 6b) is moved outward. A vector force Fd1 expanding 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 (the frame suspension members 4, 4) so as to oppose the vector force Fd1, so that the vector force Fd1 is Canceled by Fd2. That is, the posture in which both the upper and lower sides of the link mechanism in the unfolded form are convex upward in the suspension 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 directions of the forces received by the respective members are aligned, so that the posture is further stabilized and the allowable weight of the laundry is maximized. Here, as the allowable weight of the laundry to be hung decreases as the angle γ becomes 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 due to play, friction, torsion, distortion, expansion and contraction, etc. 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 state. Therefore, the position of the connection support member 3 is preferably equal to or higher than the position of the hinge portion 7. In consideration of these, in the first embodiment of the present invention, as described above, the restoring force R1 of the frame suspension member 4 is also used for maintaining the posture. When the inclination angle θ of the frame members 6a and 6b in the unfolded form is equal to or larger than 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. Also, the attitude of the deployed form can be maintained by the weight of the clothesline.

  Next, the position of the frame hanging portion 5, which is one of the important elements in the above-described link mechanism, will be described.

  Regarding the position of the frame suspending portion 5, in addition to "relative relationship with the frame suspending member 4 that determines the operation of the link mechanism", "suspension balance in a clothesline 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 hanging member 4 that determines the operation of the link mechanism”, the distance L2 between the hinge 7 and the frame hanging member 5 and the length of the frame hanging member 4 in the XZ plane direction are set. It is preferable that the length from the length L1 is not so different. This is because, when L2 >> L1, the link mechanism cannot reach the horizontal posture of the frame members 6a and 6b even with the elastic deformation of the suspension member, and when L2 << L1, At the time of the unfolding mode, the posture of the frame suspending member 4 rises, and it becomes impossible to take a substantially planar posture in which each of the frame suspending members 4 protrudes largely outward with respect to the frame members 6a and 6b. This is because it becomes impossible to maintain the posture of the unfolded form and disperse and suspend.

  Next, from the viewpoint of "hanging balance in the clothesline for load distribution", the frame members 6a and 6b in which the weight burden of the dried clothes on the clothesline becomes larger than the central region of the clothesline in the X direction, and Preferably, for example, a position of about 1/3 in the longitudinal direction of the frame is used so that the frame hanging portions are appropriately separated from each other and can evenly receive the load of the laundry.

  By doing so, the frame members 6a and 6b, which are heavy in the weight of the clothes to be dried by the clothes drying equipment, are suspended on the virtual plane connecting the four frame hanging parts 5 to the central region of the clothes drying equipment in the X direction. This makes it possible to eliminate the state in which the load caused when the clothes are dried is concentrated on a local portion (a part of the hanging portion or the hinge portion).

Finally, the viewpoint of "distance between the clothesline and the frame in the deployed 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 portion length e1 (*) of the hanging member 2”.
It is.
(*) The length of the hanging member 2 is such that the entire hook portion 10 can at least protrude outside (upper portion) in the X direction of the frame members 6a and 6b in the storage configuration of FIG. The linear portion length e1 below 10 is a value determined by the design specifications of the suspension distance h (FIG. 5 (e)) from the rod to the frame member 6 in the unfolded form when the frame member 6 is opened.

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

  As the length L2 is longer, the suspension distance h can be shorter, but as the length L2 is longer, the position of the frame suspension portion 5 is set to be gradually farther than the hinge portion 7 of the frame member 6, so that the frame member 6 is closed. The force to be applied to both ends of the frame member 6 when unfolding, when compared to leverage, the both ends of the frame member 6 correspond to the point of force, the frame suspension 5 corresponds to the fulcrum, and the hinge 7 corresponds to the point of action. As the force grows heavier, deployment becomes more difficult. Actually measuring the length of L2 that can be opened without difficulty in practical use, it was found that if the length of the frame member 6a, 6b was about 45% or less from the center of the length in the X direction, it was opened without difficulty. Conversely, the shorter L2 is taken, the less force is required when unfolding the frame 4, but this time it is necessary to increase the length of the hanger 2 and the longer the suspension distance h. In a relationship. If the setting of the hanging distance h is too long, the laundry is easy to touch the floor when the laundry is dried, such as a condominium veranda, where the vertical space is not large, so the hanging distance h should be as short as possible. .

When the maximum length 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 linear portion of the hanging member 2 is e1 when the length of the frame members 6a and 6b is 100%. The length is "100%-(45% + about 45%) １０ 10%"
That is, “e1 ≒ length of frame members 6a, 6b / 10”
And the suspension distance h is extremely short, being close to about 10% of the length of the frame members 6a and 6b. This is shorter than or equal to that of the prior art of a similar form in which the frame members 6a and 6b are held by the frame hanging member 4, and has one of the desirable characteristics as the clothes drying apparatus 1.

  The following shows actual measurement data of the clothes drying apparatus 1 of FIG. 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 these specifications.

[Dimensions of each part]
-X direction length of frame members 6a and 6b = 420 mm
・ Y direction length of frame members 6a and 6b = 350 mm
・ Hanging distance h = 190mm
L2 length of frame members 6a, 6b = 160 mm
-L1 length of the frame hanging member 4 = 150 mm
・ Inclination θ of frame members 6a, 6b = 6 degrees ・ f1 + f2 <250g
[Laundry weight limit]
When the four innermost pinch positions 60 mm from the hinge portions 7 of the frame members 6 a and 6 b were simultaneously pulled downward with the tension gauge at the same time, the load resistance was measured. Did not break down. A load test of 10 kg or more may damage the prototype, and was not performed any more. The load-bearing performance of 10 kg or more for only some of the pinches can be said to be more than enough in practice.

  As described above, in the valley folding of the related art, a hanging tool is provided at the hinge portion in order to avoid folding, but in the configuration of the present invention, a strong force against the folding force F is intended. Power is provided and does not collapse easily.

  In order to prevent the frame members 6a and 6b in the state diagram 5 (a) of the clothes dryer 1 from inadvertently collapsing and standing, a lock mechanism (not shown) is provided around the hinge portion 7 such as an uneven surface. 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, in the deployment mode (at the time of maximum deployment), the attitude of the deployment mode can be maintained in a horizontal attitude in which the pair of frame members are aligned. It is different from the embodiment.
This will be described below with reference to the drawings.

FIG. 7 is a schematic diagram showing a developed form of the clothes drying apparatus according to the second embodiment of the present invention, and FIG. 8 is an explanatory view showing a link mechanism in the clothes drying apparatus of FIG.
First, even in the present embodiment, the frame members 62a and 62b, the frame hanging member 42, and the hanging member 22 are respectively connected to the hinge portion 72, the frame hanging portion 52, and the connection support portion 332. They are rotatably connected and supported, and these constitute a link mechanism.

  The displacement of the link mechanism exhibits the same behavior as that of the first embodiment, and after the hinge portion 72 and the frame suspending portion 52 have gone through a geometric horizontal posture in which they are aligned, they are deployed. In the form, the posture is displaced to a position exceeding this geometrical horizontal posture and held.

  However, in the present embodiment, in the horizontal posture in which the pair of frame members 62a and 62b are aligned, the hinge portion 72 and the pair of frame suspension members 42 are displaced to positions beyond the geometric horizontal posture. Because of the necessity, the configuration of the first embodiment on the premise that the frame members 62a and 62b are overhanged in the unfolded form cannot be dealt with as it is.

  Therefore, in the present embodiment, both or one of the hinge portion 72 and the pair of frame hanging portions 52 is connected to the axis (frame) in the extending direction of the frame members 62a and 62b so that the link mechanism is displaced. (The center in the width direction of the member), and is provided so as to be deviated in the vertical direction. Further, by making each of the deviating directions or the amounts of deviating different, a link mechanism similar to that of the first embodiment is provided. Displacement and behavior are realized.

  As a configuration for displacing the hinge portion 72 and the pair of frame hanging portions 52 in the vertical direction of the frame members 62a and 62b, a portion of the hinge portion 72 projecting vertically upward (toward the hanging implement) with respect to the frame. May be formed there to realize deviation from the frame members 62a and 62b, or the frame hanging portion 52 may be provided with a portion projecting vertically downward with respect to the frame. The deviation from the frame members 62a and 62b may be realized by forming the frame hanging portion 52. Of course, any of the above can be used in combination. Further, when the vertical width of the frame members 62a and 62b is sufficiently large, the hinge portion 72 and the pair of frame hanging portions 52 of the frame members 62a and 62b are provided within the range of the frame width without providing the protrusion. Deflection in the vertical direction is also possible.

  7 and 8, the hinge portion 72 is provided on a frame support member 712 connecting the pair of frame members 62a and 62b, and its position is slightly shifted vertically above the axis of the frame members 62a and 62b. In addition, the frame suspending portion 52 forms the protruding portion by the suspending portion supporting member 512 attached to the frame members 62a and 62b, and is vertically below the frame members 62a and 62b and inside the frame. A structure in which a frame hanging portion 52 is provided in the first embodiment is disclosed.

  In the unfolded state, the pair of frame members 62a and 62b in the horizontal posture are located anywhere between the hinge portion 72 that is deviated in the vertical direction and the pair of frame hanging portions 52. They may be arranged, and are in the range indicated by the arrow m in FIG. The upper limit is arranged coaxially with the hinge portion 72, and the lower limit is arranged coaxially between the pair of frame hanging portions 52.

Next, the operation and function of the link mechanism of this embodiment will be described with reference to FIG.
9 (a) to 9 (e) show a state from the closed state of the frame members 62a, 62b to the developed state of the frame members 62a, 62b. FIG. 9 (a) shows the clothesline of this embodiment. The components are folded and the frame members 62a and 62b are closed, FIG. 9 (b) is a state where the frame members 62a and 62b are starting to open, and FIG. 9 (c) is a state where the frame members 62a and 62b are open and the frame is suspended. FIG. 9D shows a state in which the member 42 is horizontal, FIG. 9D shows a state in which the hinge part 72 and the frame hanging part 52 are aligned, and FIG. 9E shows a state in which the hinge part 72 and the frame hanging part 52 Indicate a state where the pair of frame members 62a and 62b is displaced to a position exceeding the geometrical horizontal posture aligned in a straight line, and the pair of frame members 62a and 62b are in a final unfolded form in which the pair is horizontally aligned.

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

  In the present embodiment, in the state of FIG. 9D in which the hinge portion 72 and the frame suspending portion 52 are in a geometric horizontal posture of a link mechanism in which they are aligned, the hinge portion 72 and the pair of frame suspending portions are provided. The portion 52 is provided so as to be deviated in the vertical direction with respect to the axis of the extending direction of the frame members 62a and 62b, so that the pair of frame members 62a and 62b are still in a posture of being bent upward and shallowly. I have.

  Thereafter, by further opening the pair of frame members 62a and 62b, as shown in FIG. 9E, the hinge portion 72 and the frame suspending portion 52 reach a position beyond the geometrical horizontal posture in which they are aligned. The pair of frame members 62a and 62b are displaced, and a final unfolded form in which the pair of frame members 62a and 62b are horizontal and straight. At this time, since the link mechanism is designed so as to include an inflection point that changes the direction of the force acting on the frame suspending member 42 during the rotation operation, in this embodiment, the link mechanism is changed from the unfolded form to the stored form. At the time of folding, the restoring force acting on the frame hanging member 42 acts as a drag against the movement of the frame members 62a and 62b to be folded, and the posture in the unfolded form is maintained. Things.

As described above, the movement and action of the link mechanism are exactly the same as those of the first embodiment.
However, in the first embodiment, the frame member itself moves by tracing the behavior of one of the geometrical link mechanisms (the component connecting the frame hanging portion 5 and the hinge portion 7). Then, since the components connecting some of the frame hanging portions 52-the hinge portions 72 and the frame members 62a and 62b intersect at a predetermined inclination angle, when only the frame members 62a and 62b are viewed, The displacement behavior appears different from that of the first embodiment.

  Therefore, 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 section 52 and the hinge section 72 are seen. It can be seen that, during the pivoting operation associated with the unfolding / storing mode of the frame members 62a and 62b, both of them become convex upward in the hanging direction from the posture of being convex outward.

  In this embodiment, before and after this one inflection point, the pair of frame hanging members 42 and the imaginary lines V connecting the pair of frame hanging portions 52 and the hinge portions 72 respectively face each other in a convex shape. From the above postures, all of them become postures that are convex upward in the suspension 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 the present embodiment, FIG. 11 is a side view of FIG. 10, and FIG. 12 is a partial cross section near the frame hanging portion 52 taken along line aa ′ in FIG. It is an expansion 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. Further, pipe-shaped members are used as the frame members 62a and 62b, and a member connected to the hinge portion 72 and a hanging portion support member 512 provided with the frame hanging portion 52 include frame members 62a and 62b. The frame hanging portion 52 is provided at a portion protruding inward from the lower side of the frame member, and the frame hanging portion 52 is attached to the frame members 62a and 62b. On the other hand, it is slightly deviated downward (see FIG. 12).

  As described above, in the configuration in which the beam 82 is provided between the frame hanging portion 52 and the hinge portion 72, the frame hanging portion 52 is displaced below the frame members 62a and 62b as in the present embodiment. In the unfolded state, the frame member 62a and the frame suspending member 42 partially intersect with each other, so that the beam 82 and the frame suspending member 42 approach and easily interfere with each other. In this case, a part of the beam 83 is cut off as shown in FIG. 13 to prevent interference between the beam 83 and the frame suspension member 42. Also, as shown in FIG. 14, by bending the frame suspending member 43 instead of cutting out a part of the beam 82, the interference between the beam 82 and the frame suspending member 43 can be prevented.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
The present embodiment is different from the first embodiment mainly in that a stopping portion 101 for restricting the rotation of the frame hanging member 41 in the developing direction is provided in the vicinity of the connecting support portion of the connecting support member. Has become.

This will be described below with reference to the drawings.
FIG. 15 is a schematic diagram of a clothesline according to a third embodiment of the present invention when viewed from the side, FIG. 16 is an enlarged schematic diagram showing a 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 is a view showing the frame in the clothesline according to the third embodiment of the present invention. It is an operation explanatory view showing a situation of performing.

  In the present embodiment, as shown in the figure, a restraining portion 101 is formed near the connection support portion 331 of the connection support member 31 by forming a part of the connection support member 31 to project obliquely downward in the hanging direction. . The stopping portion 101 abuts on the frame suspending member 41 before reaching the unfolded state in the rotating operation of the frame member, and restricts the rotation in the unfolding direction. The posture of the frame members 61a and 61b can be maintained in the posture where the posture of the frame member 41 is slightly raised from the substantially horizontal position.

  With such a configuration, the elastic deformation of the frame member, the frame hanging portion, the frame hanging member 41, and the like due to the bending due to the weight when the laundry is hung in the unfolded state and the external force due to wind or the like. Release of maintenance of the posture in an unintended deployment form, which is caused by deformation or wear due to aging or the like, can be prevented.

  This means that a sufficient margin in design can be secured for maintaining the attitude of the link mechanism in the deployed form, which also leads to an improvement in the yield of clothes drying equipment.

  In the present embodiment, the restraining portion 101 is shown as being formed integrally with the connection support portion 31. However, a configuration in which the protrusion amount of the connection support portion 31 can be adjusted with a screw or the like may be used. Things.

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

  In FIG. 19, the point that is significantly different from the situation of the first embodiment (FIG. 5) is at the time of FIG. 19C, whereby the force applied to the frame suspension member 41 changes in the subsequent steps. Is coming.

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

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

  In FIG. 19 (c), since the frame hanging member 41 comes into contact with the restraining portion 101 earlier by the angle β, the force f11 applied to both ends of the frame members 61a and 61b before the frame hanging member 41 is aligned horizontally. The movement stops and further force f21 needs to be applied to open it.

  The length of the frame hanging member 41 is d11 at the position p1b, but reaches the state (d) from the state (c) in FIG. 19 as the frame members 61a and 61b further open, and the length d11 is extended to d21. . At this time, similarly to the first embodiment, a restoring force R1 due to elasticity is generated in the frame hanging member 41.

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

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

As described above, it can 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 unfolded form higher than the horizontal. This angle can be arbitrarily set by adjusting the amount of protrusion of the restraining portion 101 from the connection support member 31 as necessary. However, when this angle is extremely increased, the load-bearing performance is reduced to the conventional level, which is not preferable.
