Description

  The present invention relates to a lifting device for a washing machine for inserting a raising base between a waterproof pan installed in a storage section of the washing machine and the washing machine.

  In general, apartment buildings such as condominiums have washing machine storage areas that are relatively narrowly divided in the kitchen, washroom, bathroom, etc., and the waterproof pan installed on this floor A washing machine is installed on top.

  And in order to prevent water clogging and water leakage, high-pressure washing work of the drain pipe installed in each dwelling unit is regularly carried out, and in that case, the waterproof pan on which the washing machine is placed is installed. A washing hose is inserted from the provided drainage port and the drainage pipe is subjected to high-pressure washing work.

  However, in the installation situation of a washing machine in an apartment house such as an apartment, the washing machine is installed on a waterproof pan installed in a narrow washing machine storage place. There was not enough space between them to insert the cleaning hose.

  Therefore, by placing a support base such as a lifting base under the legs of the washing machine and securing a gap between the washing machine and the waterproof pan, washing is performed without moving the washing machine each time work is performed. It is only necessary to be able to insert the hose, but in order to install a support base such as a lifting base, it is necessary to lift the washing machine once.

  However, the drum-type washing machine that has been rapidly spreading in recent years has an especially heavy weight (about 80 to 100 kg) because it integrally has a function as a dryer, and the width of the storage space is narrow. It is difficult for multiple people to lift the washing machine in order to insert a support stand such as a lifting platform, and moving the washing machine forcibly may cause problems such as water leakage or malfunction, There is a risk of scratching walls and floors.

In order to solve this problem, various lift devices for lifting the washing machine have been proposed.
For example, Patent Document 1 discloses a method in which two belt strings are hung around a washing machine in an intersecting state, the belt string is attached to a liftable fork, and lifted by a manual lift, or two presser plates Is lifted by a method in which the vehicle is pushed forward from the front with the width thereof being matched, and is lifted by being sandwiched from the side.

  However, the method of lifting with a belt string and a fork in Patent Document 1 requires the belt string to hang around a narrow gap between the washing machine and the surrounding wall, so that it takes time and effort to attach the belt string. There is. Further, depending on the storage location, there may be a case where the gap with the wall is only about 10 mm, and there is a possibility that the operation is extremely difficult or cannot be performed. Furthermore, when a shelf or the like is installed above the washing machine, it may be difficult or impossible to lift it from above.

  Moreover, although the method of pinching and lifting in Patent Document 1 can cope with a case where the gap between the side surface of the washing machine and the wall is narrow, in addition to the depth of the carriage in the space in front of the washing machine, a depth substantially equivalent to the washing machine Therefore, if the space in front of the washing machine is narrow, the work may be extremely difficult or impossible.

  Furthermore, since the lift device is large in size in common with the two forms of Patent Document 1, it is difficult to carry in the room and there is a risk of damaging the walls and floors in the room.

  On the other hand, Patent Document 2 discloses a lift device that can be assembled and disassembled in order to facilitate carry-in into a room, but seven parts (base, base guide, support column, arm, holding tool, It is necessary to assemble a chain lever hoist (lifting means), and there is a problem that it takes time and effort to install the lift device.

  In addition, the lift device of Patent Document 2 has a hook attached to the tip of a suspended belt further attached to a chain lever hoist (elevating means) suspended from an arm attached to the upper portion of a column, on the side of the washing machine. It is based on a method of lifting by engaging with the handle hole to be formed (portion where the hand is put during transportation). When a shelf is installed above the washing machine, it is difficult or impossible to lift it from above. There is a possibility.

  Furthermore, in Patent Document 3, a hook member attached to the tip of a belt string that hangs down through a gantry placed on a washing machine is engaged with a recess formed on the side surface of the washing machine (a part to be put on during transport). A lift device is disclosed that does not require space above and to the side of the washing machine because of the method of lifting the pedestal with a fork.

  However, even if the lift device of Patent Document 3 is configured to be disassembled, the number of parts is large and complicated.

  Further, in common with Patent Documents 1 to 3, there is still a problem that it is difficult to carry in because of the long (high) support.

  Therefore, in view of the above-described circumstances, the present invention provides a washing machine lift in which the entire apparatus is downsized, can be easily carried into a room, and can easily and quickly perform work preparation and work. An object is to provide an apparatus.

In order to solve the above-described problems, in the lift device for a washing machine of the present invention, a base, a column fixed to the base in a vertical posture, and a lifting unit that slides vertically along the column. the fixed relative to the elevating unit, a washing machine in the longitudinal direction intermediate portion the lift portion of the thus washing machine vertically moving in a state of being disposed below the front side of the leg of the washing machine at the front side of the and the front-side leg portion only holding portion Ru is lifting the legs of the lifting portion is detachably secured to the formed support hook washing machine is supported from the rear side of the washing machine, the washing machine the front side of the when part is increased with the holding portion, so that comprise a support belt you suppress the tilting to the back side of a washing machine, an operation unit for moving the elevator portion vertically, the.

Thus, in the lift device for a washing machine of the present application, the holding portion is disposed on the front side of the front-rear direction intermediate portion of the washing machine and below the leg portion on the front side of the washing machine. When the elevating part is vertically moved in this state and the holding part is raised, only the leg part on the front side of the washing machine is raised. By raising only the front leg portion of the washing machine, the washing machine is tilted to the back side.
Here, in the lift device of the washing machine of the present application, the washing machine is supported from the back side by the support belt. Thereby, when the leg part of the front side of the washing machine is lifted together with the holding part as described above, the tilting of the washing machine toward the back side is suppressed by the support belt. For this reason, even if a holding part raises only the leg part of the front side of a washing machine, the whole washing machine can be raised. Therefore, the size of the holding portion in the depth direction may be as long as the front leg can be placed, and the height of the lift device may be lower than the height of the washing machine.

  The space above the washing machine should be high enough to reach the support belt, and the space on the side of the washing machine should have enough space to allow the belt to slide down from above. It is enough.

  Accordingly, since the entire lift device can be reduced in size, it can be easily carried into the room, and work preparation and lifting work in a narrow washing machine storage place can be easily performed.

  Hereinafter, a lift device 10 for a washing machine according to an embodiment of the present invention will be described with reference to the drawings shown in FIGS. In the following description, the configuration of the lift device 10 will be described first, and then the procedure for raising the washing machine 20 by the lift device 10 will be described. In each drawing, the front end side of the mounting portion 14a of the lift device 10 is defined as the front side, and in the washing machine 20, the side facing the lift device 10 is defined as the front side.

  As shown in FIGS. 1 and 2, the lift device 10 includes a base 11, a support column 12, an elevating unit 13, a holding unit 14, a step platform 15, a support belt 16, a hand handle 18 and a pressure reducing valve 19. The holding unit 14, the step platform 15, the support belt 16, and the hand handle 18 are configured to be detachable from the main body of the lift device 10.

  The base 11 is a rectangular plate-shaped base that is horizontal to the floor surface. In the present embodiment, the base 11 is made into a carriage to facilitate movement in the front-rear direction (right-left direction in the figure).

  The support column 12 is fixed in an upright position with respect to the base 11, and includes a columnar guide shaft 12 a that guides the elevating part 13 in the vertical direction.

  The raising / lowering part 13 consists of the cylindrical part of a hydraulic cylinder in a present Example. It is connected so as to be slidable in the vertical direction with respect to the base 11 and the support column 12 through an engaging portion 13a engaged with the guide shaft 12a. A piston (not shown) is moved up and down to expand and contract the hydraulic cylinder. Further, a hooking portion 13b for hooking the holding portion 14 is formed on the front side (right side in the figure), and a support hook 13c for hooking the support belt 16 is formed on the upper end.

  The holding portion 14 has a fork shape having a mounting portion 14a for mounting a leg portion 21 (see FIG. 4 and the like) on the front side of the washing machine 20 described later at the front end (the right end in the drawing), and has a rear end ( A hole (not shown) formed at the left end of the figure is hooked on the engaging part 13b and is fixed to the elevating part 13 so as to move up and down in conjunction with the elevating and lowering of the elevating part 13.

  The step platform 15 has a rectangular plate shape, and is mounted by hooking a notch (not shown) to a hooking portion 11a formed at the rear end (the left end in the drawing) of the base 11. As will be described later, when the washing machine 20 is lifted by the placement portion 14a of the holding portion 14 and the support belt 16, a load is applied to the front side (right side in the drawing) of the lift device 10. At this time, when the operator works while riding on the platform 15, the load applied to the lift device 10 is balanced, and the work can be performed more safely.

  The support belt 16 is hung on the back surface of the washing machine 20 described later to support the back surface of the washing machine 20 (see FIG. 5 and the like), and is lifted and lowered by being hooked on a support hook 13c formed at the upper end of the lift unit 13. It is fixed to the part 13.

  The operation portion 17 is provided with a mounting portion 17a that is pivotally supported with respect to the base 11 and formed in a cylindrical shape. A hand handle 18 is detachably inserted into the mounting portion 17a. The When the hand handle 18 is inserted in the mounting portion 17a, if the rocking is made in the front-rear direction (the left-right direction in the figure), the hydraulic cylinder is extended, the elevating part 13 is raised, and when the pressure reducing valve 19 is turned, the hydraulic cylinder is contracted. Then, the elevating part 13 is lowered. The swinging direction of the hand handle 18 is not limited to the present embodiment, and may be swung in the left-right direction (the depth direction in the drawing). Further, a foot pedal type may be used.

  Further, in this embodiment, a hydraulic cylinder is used as a means for raising and lowering the holding portion 14, but other means such as a hydraulic actuator can be used as long as the holding portion 14 is vertically raised and lowered along the support column 12. May be used.

  The support belt 16 is preferably formed in a belt shape knitted with resin fibers such as polyester having excellent tensile strength, and the hydraulic cylinder (elevating part 13) is formed of steel having excellent strength. The other components are preferably made of aluminum that is easy to process and lightweight.

  In the lift device 10 configured as described above, a procedure for installing the raising stand 40 between the washing machine 20 and the waterproof pan 30 will be described.

  First, as shown in FIG. 3, the holding unit 14 is mounted on the elevating unit 13, and is arranged so that the tip of the mounting unit 14 a of the holding unit 14 faces the front side of the washing machine 20. At this time, the step board 15, the support belt 16, and the hand handle 18 are not attached.

  Next, as shown in FIG. 4, the washing machine 20 is tilted to the back side, the front-side leg portion 21 is lifted, and the lift device 10 is moved forward (moved rightward in the figure) in this state to The mounting portion 14 a is inserted between the portion 21 and the waterproof pan 30.

  Further, as shown in FIG. 5, after the step 15 is mounted, the operator gets on the step 15, hooks the support belt 16 on the back of the washing machine 20, and hooks the support belt 16 on the support hook 13c. Then, the hand handle 18 is inserted into the mounting portion 17a.

  Then, as shown in FIG. 6, when the hand handle 18 is swung, the hydraulic cylinder extends to raise the elevating unit 13 and the holding unit 14, and the washing machine 20 is raised. At this time, the placement unit 14a lifts only the leg 21 on the front side of the washing machine 20, but the back of the washing machine 20 is supported by the support belt 16 without tilting to the back side (right side in the figure) The legs on the back side also float.

  After lifting the washing machine 20 and securing a sufficient gap between the washing machine 20 and the waterproof pan 30, the raising stand 40 is fixed to the waterproof pan 30 as shown in FIG. 7.

  Then, as shown in FIG. 8, when the pressure reducing valve 19 is turned, the hydraulic cylinder contracts, the elevating unit 13 and the holding unit 14 are lowered, and the washing machine 20 is lowered.

  Finally, as shown in FIG. 9, when the support belt 16 and the step platform 15 are removed and the lift device 10 is slowly pulled out backward (to the left in the figure), the legs 21 of the washing machine 20 are placed on the raising stand 40. The work is completed.

  As described above, the lifting device for the washing machine of the present application is configured such that the back side of the washing machine is supported by the support belt so that the washing machine does not fall backward, and the leg portion on the front side of the washing machine is lifted from below.

  Therefore, since the holding part lifts only the leg part on the front side, the size in the depth direction is small, and since the washing machine is placed and lifted from below, the size in the height direction is also small. The space above the washing machine should be high enough to reach the support belt, and the space on the side of the washing machine should have enough space to allow the belt to slide down from above. It is enough. Since the entire lift device can be reduced in size, it can be easily carried into the room, and work preparation and lifting work in a narrow washing machine storage place are also easy.

  Furthermore, if the platform is provided and the operator performs the lifting operation while riding on the platform, the weight of the operator can be used to balance the lift device, and the work can be performed more safely.

  Moreover, carrying in to a room | chamber interior can be made easier by making a holding | maintenance part, a hand pushing handle | steering-wheel, and a step stand so that attachment or detachment is possible. At this time, if the holding part and the step stand are configured to be hooked on the lifting part and the engaging part provided on the base, and the push handle is configured to be inserted into the cylindrical mounting part, it takes less time to disassemble and assemble. It will end.

  In addition, the said Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the said Example itself at all.
