  Among the above-described conventional techniques, the clothesline described in Patent Documents 1 and 2 folds the left and right legs and the frame body connecting them by folding a plane, zigzag, so-called folding screen. It can be folded as if stowed. For this reason, in the folded state, the left and right legs themselves retain the width of the rectangular frame. In addition, the clothesline described in Patent Document 3 is only folded in such a manner that the link device is contracted so that the distance between the left and right legs is reduced in the state when it is folded. The left and right legs themselves retain their size. That is, in these clothes racks, since the size of the left and right legs themselves is not reduced, there is always a storage space for the width of the legs (the distance between the front and rear columns of each leg). Therefore, the space has not necessarily been sufficiently reduced.

  The present invention has been made in view of such problems in the conventional clothesline, and it is simple and quick without causing a complicated structure, and with the distance between the left and right legs constituting the basket receiving body. An object of the present invention is to provide a clothes rack that can be folded with the lateral width of the left and right legs itself reduced.

In order to achieve the above object, the invention according to claim 1 of the present invention includes a front support column and a rear support column, and both the support columns are connected to each other by a horizontal beam-shaped saddle support, The leg is formed by being connected by a connecting means below the base, and the leg is provided on the left and right, and the front strut or the rear strut of each leg is adjustable in the distance between the legs. A clothesline connected via a leg spacing adjustment link device comprising an exercise mechanism,
The connecting means for connecting the front strut and the rear strut in each of the left and right legs is constituted by a strut interval adjusting link device comprising a motion mechanism capable of adjusting the distance between the front strut and the rear strut, and The rear struts of the left and right legs are provided with the upper struts inserted in a slide manner so that the height of the rear struts can be adjusted downward. It is connected to the upper part and the upper part of the front strut, and the connection of each end thereof is such that when the upper strut is slid up and down with respect to the rear strut, the hook receiving body swings up and down. It is characterized by being connected by an even number.

  The invention according to claim 2 of the present invention is such that when the upper support column is inserted into the rear support column and is at the lowest end position, the position of the turning pair above the upper support column is the position of the front support column. The clothesline according to claim 1, wherein the clothesline is located at a higher position than the position of the turning pair in the upper part.

  According to a third aspect of the present invention, the left and right legs are rotatable about a front strut or a rear strut connected via a leg spacing adjusting link device. The clothesline according to claim 1 or 2, characterized in that. The invention according to claim 4 of the present invention is characterized in that the rear strut in each of the left and right legs is provided with a height holding means for holding the upper strut at an arbitrary height. The clothesline according to any one of claims 1 to 3.

  In the clothesline of the present invention, based on the configuration, when the storage unit is not used, that is, when folded, not only the distance between the left and right legs is reduced by the link apparatus for adjusting the leg interval, but also Among them, by raising the upper strut inserted in the rear strut (sliding upward), the strut interval adjusting link device connecting the front strut and the rear strut (hereinafter, both front and rear struts). Can reduce the interval. For this reason, the storage space can be remarkably reduced. That is, in the clothesline of the present invention, in addition to the distance between the left and right legs, the width of each leg itself (the distance between the front strut and the rear strut) can be reduced. it can.

  In the first aspect of the invention, when the upper column is inserted into the rear column and is at the lowermost position, the position of the turning pair above the upper column and the turning pair above the front column When the position is at the same height, or when the position of the swivel pair above the upper strut is lower than the position of the swivel pair above the front strut, the front and rear of each leg In order to reduce the interval between the columns, it is necessary to positively (or forcibly) slide the upper column upward, and to swing the saddle support using the counter pair at each end thereof. However, in the invention according to claim 2, when the upper support column is inserted into the rear support column and is at the lowermost position, the position of the turning pair above the upper support column is the rotation above the front support column. Since it is higher than the position of the even number, it is not necessary to positively slide the upper column upward, but by moving each leg to reduce the distance between the front and rear columns, The upper column can be slid upward by swinging. For this reason, since the space | interval between the front and back support | pillar of each leg can be made simple and quick, there exists an effect that the accommodation can be performed very easily.

  BEST MODE FOR CARRYING OUT THE INVENTION A best mode for embodying a clothes rack according to the present invention will be described in detail with reference to FIGS. The clothes rack 1 of the present embodiment includes a pair of left and right legs 10, 10 assembled by connecting and assembling metal (aluminum) pipes (circular cross-section straight pipes) through joints and the like as described in detail below. The leg spacing adjusting link device 50 is connected (connected) with a link 51 so that the distance K1 between the legs 10 can be adjusted. FIG. 1 is a front view (a view seen from the front support column side) of the clothesline 1, and is developed in a U-shape in plan view as shown in FIG. 5A. FIG. 2 is an enlarged right side view of FIG. In the present embodiment, the left and right legs 10 are the same symmetrical in front view, and will be described with reference to FIG. 2 on the right side of FIG.

  In each of the left and right legs 10 constituting the clothes rack 1 of this example, the distance K1 between the rear struts 11 located on the rear side (right side in FIG. 2) in FIG. It is connected via a link device 50 so as to be adjustable. In FIG. 1, the distance K <b> 1 between the left and right legs 10 is maximized. In this example, four links 51 having the same length are arranged so as to cross in a zigzag shape (pantograph shape), and ends and intersections of the links 51 are pivotally attached by pins 53. Each link 51 is configured to be rotatable about its axis with each pin 53 perpendicular to the paper surface as an axis (rotation center). Details of the link device 50 will be described later.

  On the other hand, as shown in FIG. 2, each leg 10 includes a front column 12 and a rear column 11 that are arranged in parallel in the front-rear direction (left and right in FIG. 2, that is, in the horizontal direction) with a gap K <b> 2. . In this embodiment, the rear column 11 is set longer (and taller) than the front column 12, and the length thereof is long so that the upper end 11 a is positioned higher than the upper end 12 a of the front column 12. ing. The rear column 11 has an upper column (indicated by a broken line in FIG. 2) 13 having an outer diameter smaller than the inner diameter of the rear column 11 inserted in a sliding manner downward from the upper end 11a. By sliding the upper support column 13 up and down, the upper end 13a of the upper support column 13 can be adjusted in height up and down. However, in FIG. 2, the upper column 13 is lowered to the lowest end position.

  And the upper end 13a of the upper support | pillar 13 inserted in this back support | pillar 11 and the upper end 12a of the front support | pillar 12 are the saddle receptacle which consists of a fixed-length pipe (straight pipe in this example) which makes a cross beam shape. Each end 15a of the body 15 is connected to each other. However, the connection was attached to the upper end of each support | pillar 12 and 13 so that the saddle receiving body 15 might rock | fluctuate centering on each edge part 15a by sliding the upper support | pillar 13 up or down. A pin 23 is pivotally attached to a support portion 21 provided on one side of a cylindrical support tube 20 and is connected so as to form a counter-joint that swings up and down. As a result, as shown in FIG. 4, the saddle receiver 15 slides the upper column 13 upward by reducing the distance K2 between the front and rear columns 11, 12, as shown in FIG. The pin 23 at each end 15a is connected so as to swing up and down about an axis (axis perpendicular to the paper surface of FIG. 2) (see FIG. 4).

  In addition, the collar receiver 15 is set so as to be inclined with the end portion 15a located on the rear column 11 side as a high position in a state where the upper column 13 is lowered to the lowest end (FIG. 2). That is, when the upper column 13 is inserted into the rear column 11 and is at the lowermost position (FIG. 2), the position of the turning pair (pin 23) above the upper column 13 is the rotation above the front column 12. It is higher than the position of the even number (pin 23). In this example, when the upper support column 13 is inserted into the rear support column 11 and is at the lowermost position, the inclination angle θ with respect to the horizontal of the saddle support 15 is set to about 25 degrees. Further, a hook receiving portion 18 is attached to the hook receiving body 15. In this example, the hook receiving part 18 is a U-shaped part (two pieces) made of a separate part from the hook receiving body 15. The scissor receiving body 15 is not limited to the one having a scissor receiving part made of a separate part. That is, the hook receiving portion may be formed on the hook receiving body itself.

  On the other hand, the front strut 12 and the rear strut 11 in each leg 10 are composed of a parallel motion mechanism in which the distance K2 between the front strut 12 and the rear strut 11 is adjustable from the middle portion to the lower end portion thereof. They are connected by a link device 30 for adjusting the column interval. In this link device 30, two links 31 having the same length are pivoted and intersected by a pin 33 whose axis is perpendicular to the paper surface of FIG. Then, one end of each link 31 is perpendicular to the paper surface of FIG. 2 at the support portion 21 provided on one side of the support cylinder 20 that is attached to a portion near the lower end of the front column 12 or the rear column 11 so as not to move up and down. 2 is pivotally attached to a pin 34, and the other end of the cylindrical slider (support cylinder) 35 is fitted on the front column 12 and the rear column 11 so as to be slidable in the vertical direction. It is pivotally attached by a pin 38 perpendicular to the paper surface. Thus, when the front strut 12 and the rear strut 11 are moved so as to widen the distance K2, the sliders 35 move downward in the front strut 12 and the rear strut 11, respectively. When the sliders 35 are moved so as to narrow the distance K2 between the rear struts 12 and the rear struts 11, the sliders 35 are moved upward in the front struts 12 and the rear struts 11, respectively. In addition, as described above, one end of each link 31 pivotally attached to the support portion 21 provided on one side of the support tube 20 near the lower end is swung around the pin 34 as a rotation center. However, it does not move along the columns 11 and 12.

  On the other hand, between the rear struts 11 in each of the left and right legs 10, the distance between the rear struts 11 is interposed via the leg spacing adjusting link device 50 by the parallel motion mechanism as described above. K1 is operably linked. That is, as shown in FIG. 1, in this link device 50, in this example, four links 51 having the same length are arranged in a zigzag manner, and the ends and intersections of the links 51 are pinned. Each link 51 is pivotally pivoted about each pin (axis perpendicular to the paper surface of FIG. 1) 53. Further, among the ends of the links 51 located on both ends (legs 10 side) of the leg spacing adjusting link device 50, the one located near the lower end of each rear column 11 is the lower end of each rear column 11. Further, a pin 53 is pivotally attached to a support portion 56 provided on a side portion of a support cylinder 55 that is attached in an outer fitting manner so as not to move up and down.

  Of the end portions of the links 51 located at both ends of the leg spacing adjusting link device 50, those located closer to the upper end of each rear strut 11 are slidably attached to the respective rear struts 11 so as to be slidable vertically. Each pin is pivotally attached to a support portion 59 provided on one side of a fitted cylindrical slider (support cylinder) 58 so as to be swingable. Further, the slider 58 and the support cylinder 55 at the ends of the links 51 located at both ends of the leg spacing adjusting link device 50 are rotatable about the axis of the column 11 with respect to the rear column 11. Yes. That is, the lower support cylinder 55 cannot be moved up and down with respect to the rear column 11 but can be rotated, while the upper slider 58 can be moved up and down with respect to the rear column 11. ing. However, the upper slider 58 is located above the slider 35 that moves the end of the link 31 that forms the column spacing adjusting link device 30 up and down. When the slider 58 is lowered, the sliders 58 and 35 come into contact with each other. Is set to

  In the clothesline 1 of this embodiment, as shown in FIG. 1, the space K1 between the left and right legs 10 is widened, and the unfolded state in a plan view and a U-shape (A in FIG. 5). In FIG. 1, a basket S is spanned over a basket receiving portion (not shown) of each basket receiving body 15 as shown by a two-dot chain line in FIG. At this time, the interval K1 between the left and right legs 10 can be adjusted to an appropriate interval by the leg interval adjusting link device 50. The distance K1 between the left and right legs 10 is widened when the distance K2 between the two struts 11 and 12 before and after the leg 10 is widened. At that time, the link forming the leg spacing adjusting link device 50 is arranged at the upper end of the slider 35 positioned on the side closer to the upper end of the column 11 among the ends of the link 31 forming the column spacing adjusting link device 30. Of the end portions of 51, the slider 58 is expanded until the lower end of the slider 58 located on the side closer to the upper end of the column 11 comes into contact. On the other hand, as shown in FIG. 3, when the distance K1 between the left and right legs 10 is reduced, the end of each link 51 constituting the leg distance adjusting link device 50 is located closer to the upper end. The positioned slider 58 slides up the rear column 11, and the interval K1 becomes narrower (smaller). That is, in this embodiment, the distance K1 between the left and right legs 10 can be adjusted by the leg distance adjusting link device 50 that forms a parallel motion mechanism.

  In this state where the distance K1 between the left and right legs 10 is narrowed, the distance K2 between the front and rear struts 11 and 12 in each leg 10 can be reduced as follows. That is, in each leg 10 of the present embodiment, the distance between the front strut 12 and the rear strut 11 by the link device 30 for adjusting the strut spacing and the connection by the turning pair mechanism at each end portion 15a of the above-described saddle receiver 15. When K2 is widened to the maximum, the upper column 13 inserted in the rear column 11 is positioned at the lowermost end, and the inclination angle θ of the rod receiving body 15 forms the most gentle inclination (FIG. 2). State).

  On the other hand, as shown in FIG. 4, when the interval K <b> 2 between the front column 12 and the rear column 11 is narrowed, the upper column 13 inserted in the rear column 11 slides upward, The inclination angle θ increases. When the distance K2 is minimized, the upper end of the upper column 13 is positioned at the highest position, and the distance K2 between the front and rear columns 11 and 12 in each leg 10 is minimized. When the distance K2 between the front and rear struts 11 and 12 in each leg 10 becomes small in this way, the slider 35 that is externally fitted to both struts of the link 31 that forms the strut spacing adjusting link device 30 is It slides up along each support | pillar 11 and 12. The upper column 13 is stable with respect to the rear column 11 without slipping out from the upper end of the rear column 11 when the distance K2 between the columns 11, 12 is minimized as described above. What is necessary is just to set to the length which can be sufficiently swallowed in the back support | pillar 11 even when it falls most. In this embodiment, when the upper column 13 is lowered to the lowermost position in the rear column 11, the lower end of the cylindrical support cylinder 20 attached to the upper end 13 a of the upper column 13 is The upper end 11a is set so as to be supported, and a cylindrical resin collar is fitted to the upper end 11a.

  That is, in the laundry platform 1 of this embodiment, in use, the both leg interval adjusting link device 50 is appropriately extended to appropriately increase the interval K1 between the legs 10 and the front strut 12 in each leg 10. And the distance K2 between the rear columns 11 is increased. At this time, as shown to A of FIG. 5, it expand | deploys by planar view and U shape. By doing so, it is used as a clothesline 1. On the other hand, when the clothes rack 1 is stored when it is not in use, as shown in FIG. To minimize. By doing so, it is as shown in FIG. 5B in plan view.

  Then, as shown in FIG. 4, the link device 30 for adjusting the strut spacing is set so that the distance K2 between the front strut 12 and the rear strut 11 in each leg 10 is reduced so that the spacing is minimized. To. As a result, as shown in FIG. 5C, in the plan view, the four struts 11 and 12 of the left and right legs 10 are approached so as to be bundled. That is, when the conventional clothes rack 1 is stored and folded, the distance K1 between the left and right legs 10 is small, but the left and right legs 10 themselves have a horizontal width (the front and rear struts of each leg 10). 11 and 12 is maintained at the interval K2 minutes). That is, since the state of B in FIG. 5 is stopped, the downsizing is insufficient, but in this embodiment, the horizontal width of each of the left and right legs 10 itself is as shown in FIG. 5C. Therefore, the storage space can be remarkably reduced.

  In addition, in this embodiment, when the upper support column 13 is inserted into the rear support column 11 and is at the lowermost position (when it is at the lowest position), the position of the turning pair above the upper support column 13 is Since it is higher than the position of the turning pair in the upper direction, as shown in FIG. 4, it is necessary to move it so that the distance K2 between the both struts 11 and 12 in each leg 10 is reduced. The inserted upper column 13 slides upward as the rod receiving body 15 swings. That is, when the upper column 13 is inserted into the rear column 11 and is at the lowermost position, the position of the rotating pair (pin 23) above the upper column 13 is the position of the rotating pair (above the upper column 12 ( When it is at the same height as the pin 23) or at a position lower than that, the distance K2 between the struts 11 and 12 in each leg 10 is reduced, but the distance between the struts is reduced. Even if it tries to move in such a manner, such an operation cannot be performed due to the presence of the saddle receiver 15.

  However, in this embodiment, if the distance K2 between the two columns 11 and 12 is reduced by the above configuration, the upper column 13 is automatically slid upward so that the rod receiving body 15 is moved to each end 15a. Therefore, the distance K2 between the two columns in each leg 10 can be easily reduced. Accordingly, when the clothes rack 1 is stored, both the columns 11 and 12 of each leg 10 can be bundled easily and quickly. Incidentally, the upper column 13 is more easily slid upward as the angle θ when the upper column 13 is inserted into the rear column 11 and is at the lowermost position (when it is at the lowest position) is larger. What is necessary is just to set suitably according to the friction at the time of the sliding of the upper support | pillar 13 in the back support | pillar 11, etc. In addition, when using as the clothes-drying stand 1 from the state accommodated in this way, contrary to the accommodation, the space | interval K2 between both the support | pillars 11 and 12 in each leg 10 is expanded, and both the left and right legs 10 What is necessary is just to widen the space | interval K1 between.

  Further, in the present embodiment, the left and right legs 10 can be rotated about the rear column 11 connected via the leg spacing adjustment link device 50, and thus are developed as the clothesline 1. The distance K1 between the legs 10 is appropriately rotated around the rear column 11 so that, for example, the front columns 12 positioned on the front front side are widened or vice versa. It can also be adjusted to be narrower. Moreover, since the rotation is possible also at the time of accommodation, the four support | pillars 11, 11, 12, and 12 which comprise the leg 10 of both sides can be bundled smaller. It should be noted that in the above-described form, the clothesline formed by connecting the tall rear column 11 of each leg 10 via the leg spacing adjusting link device 50 that is an exercise mechanism capable of adjusting the spacing K1 between the legs 10. Although embodied as a stand 1, in the present invention, the short front strut 12 in the above-described form is connected via a leg interval adjusting link device 50 comprising an exercise mechanism capable of adjusting the interval between the legs 10. It can also be embodied as a clothesline.

  In addition, in the said form, when it uses as the clothes-drying stand 1, ie, when both the front and back support | pillars 11 and 12 in each leg 10 are spread, the upper support | pillar 13 is inserted in the back support | pillar 11. Therefore, the distance K2 between the two columns is set to be the largest. However, the rear column 11 in each of the left and right legs 10 may be provided with a height holding means for holding the upper column 13 at an arbitrary height. In this way, the distance K2 between the front and rear struts 11 and 12 in each leg 10 can be stably held at an arbitrary position, so that it can be easily adjusted to the installation space of the clothesline 1. As the height holding means, for example, as shown in FIG. 6, a screw hole 11c is provided in a radial direction at an appropriate position on the wall surface 11b of the rear column 11, and the screw hole 11c is stopped from the outside. The screw 60 may be screwed and the outer peripheral surface of the upper column 13 may be pressed by the tip of the set screw 60. Although not shown, a taper screw that expands downward is formed on the outer peripheral surface of the upper end portion of the rear strut, and this screw portion is divided into a plurality (for example, two) when viewed from the axial direction of the rear strut. Then, screw the tightening nut onto the screw from above, tighten the tightening nut to reduce the diameter of the threaded portion, and tighten the upper strut that is inserted into the upper strut. Conventionally known means can be used such that the tightening may be released by loosening so as to hold it in position.

  The present invention is not limited to the embodiment described above, and can be embodied with appropriate modifications without departing from the gist thereof. For example, struts and the like are usually composed mainly of pipes, particularly pipes with a circular cross section, but for components whose mating members are not inserted in a sliding manner, such as front struts, upper struts, or links, You may comprise not only a cross-sectional shape but a solid bar. However, it is preferable to use a straight pipe or rod as a constituent element. Further, the link device is not limited to the one described above, and any link mechanism may be used as long as the distance between the legs or the distance between the front strut and the rear strut can be adjusted.
