Patent Application
20090045231
The present invention relates to a hanger and a garment folding apparatus capable of automatically folding garments.
Folding garments in households is listed as one of relatively stressful housekeeping works. Various electric and electronic housekeeping apparatuses have been developed and generally used, but no apparatus for automatically holding garments has been put to practical use. Therefore, people engaged in housekeeping strongly desire the development of an apparatus for alleviating the work of folding garments.
For industrial use, apparatuses for folding garments, especially shirts, for cleaning business are known. Patent Document No. 1 discloses an apparatus which works as follows. A garment is spread on a table with the front side up and with both side parts being hung down. Folding plates are slid to below the garment from both sides to fold the hung-down side parts of the garment. Patent Document No. 2 discloses an apparatus which works as follows. A garment is spread with the front side down on a table divided into three parts. Two side parts of the table are moved to above the garment to fold side parts of the garment. Such apparatuses are mainly used in the actual cleaning business practice.
However, an apparatus having such a structure needs to include a large working table on which the garment can be spread horizontally, which requires a large floor area. In addition, the work of spreading the garment on the table needs to be done manually and is inefficient.
By contrast, Patent Document No. 3 discloses an apparatus which works as follows in order to decrease the necessary floor area. A garment is hung on a sloped plate. Air is blown to both side parts of the garment to flap the side parts rearward. Then, folding plates are slid from both sides of the garment to the back thereof to fold the garment.

Hereinafter, an embodiment of a hanger and a garment folding apparatus according to the present invention will be described. The hanger according to the present invention is able to automatically transform to fold at least a part of a garment which is hung on the hanger, based on an external instruction. Moreover, the garment folding apparatus includes the hanger according to the present invention, and in cooperation with the hanger, allows a garment which is hung on the hanger to be folded. Therefore, the garment folding apparatus according to the present invention is capable of preferably folding a garment washed and then dried while being hung on a hanger.
The hanging pole 110 is kept at a predetermined height by a pole stand 101 in order to allow a washed garment 10 to be dried thereon. A plurality of hanger carriers 121 are attached to the hanging pole 110, and a hanger 200 is suspended from each of the plurality of hanger carriers 121. Each hanger carrier 121 has, for example, pinion gears (not shown) which mesh with a rack (not shown) that is provided on the hanging pole 110 and a driving section for rotating the pinion gears (not shown), thus being able to move in the directions of arrows 120A and 120B relative to the hanging pole 110.
On each hanger 121 suspended from the hanging pole 110, a washed garment is hung to be dried. Therefore, the garment folding apparatus is preferably installed outdoors. In the case where the garment folding apparatus is installed outdoors, the folding mechanism 450 is preferably provided with a case 490 having a roof in order to prevent the folded garment from being wetted by the rain or the like. A part of the hanging pole 110 is placed inside the case 490. The folding mechanism 450 is located inside the case 490.
In addition, the case 490 includes a driving section 471 for driving the folding mechanism 450 and a control section 472 for controlling the entire garment folding apparatus.
In order that the hanger 200 may be pulled out through an opening such as a neck of the folded garment 10, the main body section 210 has an outer shape such that, in a state where the garment 10 is supported spread by the hanger 200, a projected region of the main body section 200 on a horizontal plane fits within a projected region of the opening of the garment 10 being supported spread.
The suspension section 211 is connected to the main body section 210, and has a hook shape, for example. By inserting the suspension section 211 into a hole of a hanger carrier 121, the hanger 200 is suspended by the hanging pole 110.
The arm sections 220 and 230 are linked to the main body section 210 and provide support from inside, in a suspended state. More specifically, as shown in
From the state of supporting the garment 10 spread, the arm sections 220 and 230 are able to transform in such a manner as to fold at least a part of the garment 10. For this reason, the arm section 220 includes an arm butt 221 and an arm fore-end 222. Similarly, the arm section 230 includes an arm butt 231 and an arm fore-end 232.
The arm butts 221 and 231 are linked to the main body section 210 so as to be capable of rotating from a state of being extended in a generally horizontal direction to a state of being hung downward as shown in arrows 221A and 231A, respectively, relative to the main body section 210. Moreover, the arm fore-ends 222 and 232 are linked respectively to the arm butts 221 and 231 so as to be capable of rotating as shown by arrows 222A and 232A and arrows 222B and 232B. As a result, in the present embodiment, between the arm butt 221 and the arm fore-end 222 and between the arm butt 231 and the arm fore-end 232B, a first link portion 223 and a second link portion 224 as well as a first link portion 233 and a second link portion 234 are provided.
Therefore, when the first link portion 223 and the second link portion 224 are arranged between the arm butt 221 and the arm fore-end 222 in such a manner that the axis 223a and the axis 222a lie parallel, as shown in
Such rotating operations of the link portions may be achieved by small motors (not shown) which are internalized in the respective link portions corresponding to the respective rotation axes, or achieved by a motor which is internalized in the main body section 210 of the hanger 200 and wires which are drawn to the link portions (neither of which is shown). Moreover, the respective elements of the hanger 200 are controlled based on instructions by wireless signals which are transmitted from the control section 472 shown in
Next, with reference to
The vertical direction folding section 451 folds the garment 10 in the vertical direction. Therefore, the vertical direction folding section 451 includes bar-like folding length determining portions 431 and 432 having a first edge 431e and a second edge 432e extending along the horizontal direction, and lower end holders 441 and 442 for holding the lower end of the garment 10. The folding length determining portions 431 and 432 are linked by a link portion 430, and the folding length determining portions 431 and 432 are moved in the direction of arrow 430A or 430B by a moving mechanism (not shown). The lower end holders 441 and 442 are provided on the folding length determining portion 432. In a state where the lower end holders 441 and 442 are holding the lower end of the garment 10, the vertical direction folding section 451 may move upward while wrapping around the first edge 431e, thus forming a crease portion along the first edge. Furthermore, by moving upward the first edge 431e while wrapping around the second edge 432e, a crease portion along the second edge 432e is applied to the garment 10, whereby the garment 10 is folded in the length direction.
As described below, these elements of the folding mechanism 450 can approach, or retract from, the garment 10 at an appropriate timing under the control of the control section 471. A driving mechanism for allowing the elements to approach, or retract from, the garment 10 may be realized by a combination of known mechanical mechanisms or mechanical elements.
Hereinafter, with reference to
First, an operator hangs washed garments 10 on the hangers 200 in the state where the arms 202 and 203 are opened as shown in
After the operator finishes hanging an arbitrary number of garments 10 in this way, the garments 10 are dried by the heat of the sun as time passes like garments hung on a usual hanging pole. When the operator inputs an instruction to the control section 472 with a switch (not shown), or when a dryness sensor (not shown) detects more than a certain level of dryness of the garments 10, the hanger carrier 121 that is the closest to the folding mechanism 450 moves in the direction of arrow 120A to enter inside the case 490, and stops. As a result, the hanger 200 and the folding mechanism 450 start a folding operation for the garment 10. Hereinafter, with reference to
First, as shown in
More specifically, the first link portions 223 and 233 rotate relative to the arm butts 221 and 231, and the arm fore-ends 222 and 232 rotate by 90 degrees in the directions of arrows 222A and 232A around the axes 223a and 233a, thus resulting in a state shown in
Since the arm section 220 and the arm section 230 preferably constitute an obtuse angle, rotation of the arm fore-ends 222 and 232 in the directions of arrows 222A and 232A causes the tips of the arm fore-ends 222 and 232 to be slightly (e.g., by about 5 cm) elevated from the plane on which the first link portion 223, the second link portion 224, and the first link portion 233 and the second link portion 234 are located. As a result, the garment 10 is folded in the width direction, without its shoulder ends dropping off the arm fore-ends 222 and 232.
From this state, the garment side part holders 411 and 412 proceed in the directions of arrows 411A and 412A while rotating in the directions of arrows 411R and 412R, and as shown in
As the first transformation is completed, the arm sections 220 and 230 of the hanger 200 complete the operation of folding the garment 10 in the horizontal direction. The garment 10 is folded in the vertical direction by the length direction folding section 451. The arm sections 220 and 230 transform in such a manner that the hanger 200 can be pulled out of the garment 10. This is achieved by the arm sections 220 and 230 undergoing transformations such that the projected regions of the arm sections 220 and 230 on a horizontal plane fit within the projected region of an opening of the garment. Hereinafter, the folding of the garment 10 in the horizontal direction and the transformations of the arm sections 220 and 230 will be described.
After the gripping operation for the garment 10 by garment side part holders 411 and 412, as shown in
Next, as shown in
Next, as shown in
In this manner, the arm sections 220 and 230 complete their preparation for making a transform to enable the hanger 200 to be pulled out of the garment 10.
Next, a folding operation for the garment 10 by the length direction folding section 451 is performed. For the garment 10 having completed its folding operation in the width direction and now being hung by the hanger 200, the folding section 451 approaches the garment 10 in such a manner that the folding length determining portions 431 and 432 will abut on the back side, as shown in
From this state, the link portion 430 is rotated by about 180 degrees around the first edge 431e, as indicated by arrow 431A. Thus, as shown in
Furthermore, the link portion 430 is rotated by about 180 degrees around the second edge 432e, as indicated by arrow 432A. As a result, as shown in
Next, an operation of removing from the garment 10 the hanger 200, the length direction folding section 451, and the folding width determining portion 420, which are with the folded garment 10, will be described.
First, by a mechanism not shown, the folded garment 10 is supported so as not to unfold. For example, arms or the like approach the garment 10 and support the garment so as to prevent it from unfolding. Next, the lower end holders 441 and 442 are moved in the direction of arrow 440B, so as to be accommodated into the folding length determining portion 432. Moreover, in the hanger 200 as shown in
As shown in
Thus, folding of the garment 10 is completed. After folding of the garment 10 is completed, the folding width determining portion 420 and the vertical direction folding section 451 move downward, for example, and the hanger 200 which is now free from the garment 10 is moved to the rear of the case 490. Thereafter, a next hanger 200 having a garment 10 hung thereon moves into the case 490, and a folding operation for the garment 10 is repeated.
Thus, with the hanger and garment folding apparatus according to the present invention, a garment is automatically folded while being suspended on a hanger, whereby an automated folding operation is realized without incurring manual work such as placing the garment into the folding apparatus. Moreover, since the garment is folded while in a suspended state, the floor area occupied by the garment folding apparatus is reduced. Furthermore, since no compressor or the like is used, generation of a large operation noise is prevented, resulting in suitability for use in households. Since the garment is folded while being tensioned, it is also possible to obtain a neat folded state free of wrinkles.
The hanger and the garment folding apparatus according to the present embodiment admit of various modifications. For example, a plurality of air outlets 200h may be provided in the arm sections of the hanger as shown in
Moreover, prior to the second transformation of the arm sections 220 and 230 shown in
Alternatively, as shown in
As a result, during the second transformation, it can be ensured that the tips 222t and 232t of the arm fore-ends 222 and 232 do not intersect the sleeve roots 10r of the garment.
Moreover, although the folding width determining portion shown in
The hanger and the garment folding apparatus according to the present invention are able to automatically fold a garment which is suspended on a hanger, and thus are useful because they realize a garment folding operation free of manual work, without occupying a large floor area.
