TECHNICAL FIELD OF THE INVENTION
The present invention relates to a clothesline assembled by connecting (connecting) pipes (or rods) with joints.
[0002]
[Prior art]
Various types of clothes racks of this type have been developed. FIG. 11 shows one example. In this apparatus, in a plan view, a column is vertically assembled via a joint on a base formed by assembling pipes in an H-shape and at the center of opposed parallel pipes forming the base. At a position near the upper end, the two pillars are laterally connected by a connecting member (pipe) to form a frame, and a rod receiver is mounted on an upper portion of the frame as follows. That is, the upper support is interpolated downward from the upper ends of the two supports by a sliding method, and a rod receiver (pipe) provided with a plurality of rod supports is bridged above the two upper supports. Connected. The upper support is configured to be adjustable to a desired height by sliding the upper support up and down with respect to the lower support, and the upper support is held at an arbitrary height position, such as a tightening nut. Height maintaining means is provided.
[0003]
Thus, the upper column inserted into the column can be freely slid up and down or lowered, and, for example, hold an arbitrary height position by height holding means provided at the upper end of the column. It is configured to be able to. In this way, the height of the rod receiver can be adjusted, and the rod receiver can be lowered and stored when not in use. Note that, for example, two pole supports (U-shaped bodies) are attached to the pole receiver at intervals as shown in the figure. Usually, such clothes racks are arranged in a room or the like with a proper distance between them as a pair of left and right clothes.
[0004]
[Problems to be solved by the invention]
However, in this clothesline, when the rod receiving body is gripped and pulled up (lifted) or lowered (pushed down), both upper struts to which it is connected are inserted in both struts in a sliding manner. There was a problem that both the upper struts would not move smoothly unless an average force was applied. In other words, when trying to adjust the height of the rod receiving body and try to raise it, the two upper supports must be lifted on average, or they will be one-handed and will not lift smoothly. was there. Conversely, there is a similar problem when pushing down the rod receiver.
[0005]
In addition, in the above-mentioned conventional clothes rack, a plurality of pole supports are attached so that a plurality of poles can be hung, and a plurality of poles are hung substantially in parallel on a clothes rack arranged in parallel at intervals during use. Will be done. However, in the above-mentioned conventional clothes rack, since the plurality of poles have the same height, when hanging an object on the pole located in the back as viewed from the user, or when picking up the object, the front pole becomes an obstacle. , The task is cumbersome. Furthermore, in the case of drying by solar heat or natural ventilation, the drying action of the laundry hung on the back rod is hindered by the presence of the laundry hung on the front pole. Among these, there is a device provided with a mechanism capable of adjusting the height of the front and rear rod supports, but only a device having a complicated structure and a troublesome adjustment thereof.
[0006]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a clothesline that can easily adjust the heights of a rod receiver and front and rear rod receivers without complicating the structure. And
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 of the present invention connects two columns vertically arranged substantially in parallel with a connecting member at arbitrary positions above and below the columns, and each of the columns has The upper support is interpolated in a sliding manner downward from the upper end of the upper support, and a rod support provided with a plurality of rod supports is connected in a bridging manner above the two upper supports, and the upper support is connected to the upper support. In a clothesline that is configured so that the height of the rod receiving body can be adjusted by sliding up and down with respect to the support, and that has height holding means for holding the upper support at an arbitrary height. ,
The rod receiver is configured to be extendable by inserting an insert into a cylindrical portion in a sliding manner, and to connect each end of the rod receiver to the upper column by the two upper columns. When one of the rods is slid up and down with respect to the column, the rod receiver is connected in a pair so as to swing up and down.
[0008]
In the above means, when the rod receiver is gripped and lifted, for example, when a lifting force acts intensively on one upper column in a unilateral state, the one upper column is mainly lifted and the rod receiver is lifted. Slidably extends while swinging, and tilts so that one of the upper columns can be lifted. Then, when the lifting force is intensively applied to the other upper support from the inclined state of the rod receiving body, the other upper support is mainly lifted. At this time, the rod receiver shrinks as the other upper column is lifted. Further, when the other upper column is lifted, the end of the rod receiving body connected to the other upper column becomes higher than the end connected to the one upper column, and The receiving body slides and extends while swinging.
[0009]
As described above, according to the present invention, when the rod receiver is lifted, even if it is one-handed, it is possible to lift one of the upper supports, so that the lifting of the rod receiver can be performed smoothly. Of course, if both upper struts are evenly loaded, they will lift on average and can be lifted easily. As described above, according to the present invention, it is possible to provide a clothesline that can easily move the rod receiver up and down without complicating the structure. Moreover, since such a manner of lifting can be made, when two laundry stands of the present invention are prepared, and both are arranged in the left and right in a plan view, in parallel, for example, the pole to be hung out of the poles to be hung Since the rod receiver can be inclined so as to be lower at a desired height position, for example, when two rod receivers are provided, two rods to be passed are desired in front and rear. Can be changed to height.
[0010]
Further, the invention according to claim 2 of the present invention has a length holding means for holding the rod receiver at an arbitrary length. When the upper support is held at an arbitrary height by the height holding means, such a length holding means is basically unnecessary, but has such a length holding means. In the object, the rod receiver is stabilized.
[0011]
The invention according to claim 3 of the present invention is characterized in that a plurality of the connecting members are provided, and each of the connecting members is configured to be extendable and retractable by inserting an insert into the cylindrical portion by a slide method, and to slide the connecting members in a sliding direction. 3. The clothesline according to claim 1, wherein an axis extending to the support is substantially parallel and substantially perpendicular to the support. In this case, the distance between the poles and the upper poles can be adjusted by the structure, and therefore the distance between the pole supports can be adjusted, which is convenient.
[0012]
Further, the invention according to claim 4 of the present invention is characterized in that the connection between each end of the connecting member and the column is performed when one of the two columns is relatively moved up and down. A swing for regulating the swing of the connecting member relative to the strut when the two struts are connected to each other so as to swing up and down by a pair, and when the two struts stand substantially vertically on one plane. The clothesline according to claim 3, further comprising a movement restricting means.
[0013]
The clothesline according to claim 3, further comprising a swing regulating means for regulating the swing of the connecting member with respect to the pillar when the two pillars stand substantially vertically on one plane. Therefore, the shape of the clothesline is maintained by the regulation. On the other hand, when not in use, the support, the upper support inserted therein, the linking material, and the rod support form a link mechanism that folds both supports close to each other. Reduction can be achieved.
[0014]
In addition, in the laundry stand according to claim 3 or 4, as described in claim 5, it is assumed that the laundry has length holding means for holding the connecting member at an arbitrary length. Good. This is because the distance between the columns can be maintained at an arbitrary length, and the clothesline is stabilized.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
A first embodiment of a clothesline according to the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 denotes a clothesline, which is formed from two vertical pipes 2 and one horizontal connecting member (pipe) 3 via a joint 4 or the like so as to form an H shape in plan view. A column (pipe) 6 of the same length is vertically provided via a joint 10 at the center of the opposed parallel pipes 2, 2 forming a base 5 on the base 5. At a position near both upper ends, the two columns 6 are connected to each other by a connecting member (pipe) 8 via a joint 11, and the two columns 6 and the connecting members 3 and 8 have a rectangular shape in a front view (FIG. 2). A frame 12 is formed.
[0016]
Then, the upper column 15 having an outer diameter smaller than the inner diameter of the column 6 is inserted downwardly from the upper end of each of the columns 6 by a sliding method, and a U-shape is formed above the two upper columns 15. A rod receiver (pipe) 17 provided with two rod receivers 16 is connected in a bridging manner. Thus, the height of the rod support 17 can be adjusted by sliding the upper support 15 up and down with respect to the support 6. In addition, in this embodiment, in order to hold the upper support 15 at an arbitrary position, a height holding means by tightening the tightening nut 19 is provided. Although not shown in detail, a taper screw that expands downward in diameter is provided on the outer periphery of the upper end of the support 6, and this screw is divided into two when viewed from the axial direction of the support 6, A tightening nut 19 is screwed onto the screw, and the diameter of the screw portion is reduced by tightening the tightening nut 19, and the inserted upper support 15 is tightened, so that the upper support 15 can be moved to an arbitrary position. This is a conventionally known means that is set so as to be held by. The above configuration is the same as that of a conventional clothesline made of a pipe having a circular cross section.
[0017]
However, in the present embodiment, the rod receiver 17 is configured to be extendable and retractable by inserting an insert (small pipe) 21 having an outer diameter smaller than the inner diameter into the cylindrical portion 18 by a slide method. 17, that is, the cylindrical portion 18, and the projecting pieces 20 a of the joints 20, 20 attached to the respective base ends (ends closer to the respective upper supports 15) of the inner insert 21, are attached to the respective upper supports 15. A U-shaped link mechanism, which is relatively movable, is connected via a pin 25 to a protruding piece 23a, which has a U-shape in plan view and is protruded inward from each of the T-shaped joints 23 near the upper end. . That is, the connection between the joint 20 at each end of the rod receiving body 17 (hereinafter, also referred to as each end) and the T-shaped joint 23 (hereinafter, also referred to as upper end) near the upper end of the upper support 15, The pin 25 is connected by a rotatable pair rotatable around an axis (pin 25) perpendicular to the paper surface of FIG. 2. When one of the upper supports 15 is slid up and down with respect to the support 6, The rod receiving body 17 is configured to swing relatively up and down about the pin 25. In the present embodiment, a set screw 27 is screwed in a radial direction on an outer peripheral surface of a portion near a tip end of the cylindrical portion 18 as a length holding unit that holds the rod receiving body 17 at an arbitrary length that is expanded and contracted. It is set so that the insert 21 is pressed by the tightening of the set screw 27 to maintain the length.
[0018]
When the laundry table 1 of the present embodiment is held on the flat surface such as a floor with the base 5 having the H shape in plan view, when the rod receiving body 17 is gripped and lifted, the following is performed. is there. That is, when the rod receiving body 17 is gripped and lifted, for example, when the lifting force acts intensively on the right upper column 15 in FIG. 2 in a single-handed state, as shown by a two-dot line in FIG. The right upper column 15 is lifted up, as shown by the solid line in FIG. At this time, the rod receiving body 17 extends while sliding about the pins 25 at both ends while swinging, and inclines so that the right upper support 15 can be lifted.
[0019]
On the other hand, when the lifting force is intensively applied to the left upper column 15 in FIG. 4 from the inclined state of the rod receiving body 17, the left upper column 15 is lifted up, as shown by a solid line in FIG. For example, the entire rod receiver 17 is lifted. At this time, the length of the rod receiving body 17 is reduced until the left upper column 15 is lifted and becomes horizontal, and the rod receiving member 17 is further lifted. The end connected to the left upper column 15 side is moved to the right upper column. When the height of the rod receiver 17 is higher than the end connected to the support 15, the rod receiver 17 swings around the pin 25 and slides and extends.
[0020]
In this way, even when the rod support 17 is lifted, the upper support 15 can be lifted one by one, so that the rod support 17 can be lifted smoothly. As a matter of course, if both upper struts 15 are evenly loaded, they will be lifted on average, and at this time, both ends of the rod receiving body 17 are connected to the upper strut 15 by a turning pair, so that it is smooth. To lift. It should be noted that when the rod receiving body 17 has reached the desired height and inclined state, the height is maintained by tightening the tightening nut 19, and the rod receiving body 17 may be used as a clothesline. In the present embodiment, an example in which a set screw 27 is screwed as the length holding means of the rod receiver 17 has been exemplified. However, basically, there is no problem in using the clothesline without the tightening, but by tightening the set screw 27, the position of the rod receiver 17 can be further stabilized. When the rod receiving body 17 is lowered, it can be easily performed in a similar manner.
[0021]
As described above, in the present embodiment, the vertical movement of the rod receiver 17 can be easily performed without complicating the structure. Therefore, when two clothes racks 1 according to the present embodiment are prepared and arranged in a symmetric and parallel manner in the left and right plane view, as shown in FIG. One of the poles S can be set to a low position at a desired height position, for example, with respect to the pole S on the front side. For this reason, when, for example, two rod receivers 16 are provided on the rod receiver 17, the two rods S to be passed can be changed to a desired height in the front and rear directions. It is convenient.
[0022]
Next, a second embodiment of the present invention will be described with reference to FIG. 6. The clothesline 51 of the present embodiment can be said to be an improvement of the above embodiment, and there is no essential difference. The same parts are denoted by the same reference numerals, and only the improvements (differences) will be described.
[0023]
That is, the clothes drying table 51 is provided with two connecting members 37, 37 having the same configuration, and the two connecting members 37 are respectively provided in the cylindrical portion 38 with an outer diameter larger than the inner diameter. A small insert 41 is inserted in a sliding manner so as to be expandable and contractible. The two connecting members 37 have their axes G extending in the sliding direction substantially parallel to each other, and are substantially perpendicular to the column 6. However, in the present embodiment, as the length holding means for holding the two connecting members 37 at an arbitrary length, the set screw 27 is screwed in the radial direction on the outer peripheral surface of the cylindrical portion 38 near the front end. It is set so that the length of the rod holder 17 is maintained by pressing the inner insert 41 by tightening the set screw 27 and maintaining the length thereof. ing. In addition, the base end of the cylindrical portion 38 and the base end of the insert are connected and fixed to the joints 10 and 11 of the both columns 6, respectively, and the two connecting members 37 and the both columns 6 form a rectangular frame. Is composed.
[0024]
In the laundry table 51 having such a configuration, in the state shown by the solid line in the figure where the set screw 27 of the connecting member 37 is tightened, the same operation and effect as in the above embodiment are obtained. That is, in the state shown by the solid line in the drawing, the rod receiving body 17 can be moved up and down corresponding to the up and down movement of each upper support 15 and can be inclined.
[0025]
In addition, in the present embodiment, the two connecting members 37, 37 are each configured to be extendable and retractable by inserting the insert 41 into the cylindrical portion 38 in a sliding manner, and extend the axis G extending in the sliding direction. Since they are substantially parallel to each other and are substantially perpendicular to the column 6, when the set screw 27 of the rod receiver 17 and the connecting member 37 is loosened, as shown by the two-dot line in the figure, both columns 6 Can be expanded or narrowed by an appropriate amount according to the slidable amount of the insert 41. That is, since the interval between the two columns 6 can be adjusted, the interval can be used as an appropriate interval according to the installation location, and even if the number of the rod supports 16 is increased, the interval can be maintained, which is convenient. The expanded and contracted connecting member 37 has an arbitrary length, and if the set screw 27 is tightened, the shape of the rectangular frame is stabilized.
[0026]
Furthermore, a third embodiment of the present invention will be described with reference to FIGS. 7 and 8. However, the clothesline 61 of the present embodiment should be said to be a further improvement of the above-described embodiment shown in FIG. Therefore, the same portions are denoted by the same reference numerals, and only the improvements (differences) will be described.
[0027]
In this laundry stand 61, the connection between each end of the two connecting members 37 and the support 6 in the above-described embodiment is performed by connecting each end of the rod receiver 17 and the upper support 15 in the first embodiment. In the same manner as described above, they are connected via a pair of pins 25 in a pair. That is, the projecting pieces 20 a of the joints 20, 20 attached to both ends of the connecting member 37, that is, the respective base ends (ends closer to the respective upper supports 15) of the cylindrical portion 38 and the insert body 41, U-shaped link mechanisms, which are relatively movable, are connected via pins 25 to protruding pieces 23a protruding inwardly of the T-shaped joint 23 near the upper end of the upper support 15 respectively. That is, the connection between the joint 20 at each end of the connecting member 37 (hereinafter, also referred to as each end) and the T-shaped joint 23 (hereinafter, also referred to as upper end) near the upper end of the upper support 15 is defined by a pin. 25, the connecting members 37 are connected by a turning pair that swings up and down when one of the two columns 6 is relatively moved up and down.
[0028]
However, in order to maintain the shape of the rectangular frame formed by the two supports 6 and the two connecting members 37, when the two supports 6 stand substantially vertically on one plane, the connection to the supports 6 is made. In the present embodiment, a bracket 65 is attached as a swing regulating means for regulating the swing of the member 37. However, the bracket 65 is rotatably mounted at one end to a shaft 6a provided on the column 6 so as to form a strut between the column 6 on the left side in the figure and each connecting member 37. A hook 66 is formed at the other end (tip), and is configured to be engaged with a shaft 68 attached to the connecting member 37 in a state where the support column 6 and the connecting member 37 make a right angle. In the figure, the two brackets 65 are both locked to the shaft portion 68 of the connecting member 37, but when the lock is released, both are set to hang down by their own weight.
[0029]
In the laundry stand 61 of the present embodiment, when the two columns 6 stand substantially vertically on one plane via the base, the two brackets 65 allow the two columns 65 to move between the column 6 and the connecting members 37. By restricting the rocking (displacement) of each other, the relative movement between the column 6 and the two connecting members 37 is prevented except for the expansion and contraction of each connecting member 37. Configure the platform. On the other hand, when not in use, the two brackets 65 can be easily folded and stored by releasing the engagement of the connecting member 37 with the shaft 68. That is, the clothesline 61 constitutes a skeleton diagram link mechanism as shown in FIG. 8A in a front elevation view. Therefore, as shown in the skeleton diagram shown in FIG. 8B, the clothes rack 61 connects the support 6, the upper support 15 inserted therein, the connecting member 37, and the rod receiving body 17 to each other. The column 6 can be folded so as to be close to the column. Therefore, the space for storage can be reduced.
[0030]
In this embodiment, the bracket 65 is used as the swing restricting means for restricting the swing of the connecting member 37 with respect to the column 6. It suffices if the relative movement in the turning couple can be regulated, and therefore, the specific configuration can be arbitrary. For example, as shown in the enlarged view of FIG. 7, the pipe 70 is slidably connected to the protrusion 20 a of the joint 20 at the end of the connecting member 37 and the protrusion 23 a of the joint 23 on the support column side with substantially no gap. A sleeve may be externally fitted, and the pipe (sleeve) 70 may be externally fitted to the link portion to restrict swinging. In this case, when folding, the pipe 70 may be slid horizontally to release the restriction.
[0031]
Although not shown, the connecting member 37 can also be embodied as one having the same length (non-stretchable) in the clothesline 61 of FIG. Further, when the length of the connecting member 37 can be adjusted, the length holding means for holding the length at an arbitrary length is replaced with the set post 27 in the upper column in the first embodiment. The structure of the tightening nut 19 used for fixing the fixing member 15 by changing its length may be used.
[0032]
The present invention is not limited to the above-described embodiments, and can be embodied by appropriately changing the design without departing from the gist of the present invention. For example, in the above description, an independent (one) laundry table is described as one of a pair of laundry tables. However, the laundry table of the present invention has two of them, both of which are in a plan view. , Can be embodied as being connected in the horizontal direction. The struts and the like constituting the components of the present invention are usually mainly constituted by pipes, particularly pipes having a circular cross section, but components in which the mating member is not inserted in a slide shape, such as an upper strut or the like. The insert body is not limited to the cross-sectional shape, and may be constituted by a solid rod. However, it is preferable to use straight pipes or rods as constituent elements.
[0033]
【The invention's effect】
As is apparent from the above description, according to the present invention, it is possible to easily provide a clothesline that can easily adjust the height of the rod receiver and the front and rear rod receivers without complicating the structure.
