Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lifting device for a wash basin, and more particularly to a lifting device for a wash basin capable of adjusting the height position of a wash basin body having a wash basin. Regarding improvement.

[Conventional technology and its problems]

For example, in a home wash basin, etc., it is preferable that the height of the wash basin body having the wash basin is adjustable, but the wash basin is made of a relatively heavy material such as earthenware or metal. In the case of the washbasin main body, the total weight of the washbasin main body becomes considerably large.

Therefore, for example, when the washbasin body is configured to be able to move up and down along the fixed columns and the like, the connecting structure between the washstand body and the fixed columns and the like is set to be a sturdy structure as a whole.

On the other hand, when making the washbasin body movable up and down along a fixed prop, etc., for example, as proposed in Japanese Patent Laid-Open No. 64-52419, a vertical roller is provided between the washbasin main body and the fixed prop. And so on.

In this case, the connecting structure portion including the rollers and the like must have a certain allowance such as a gap that allows the rollers and the like to roll, and when considering the accuracy in processing and assembling, this allowance is required. Set somewhat larger.

However, since the above-mentioned allowance is a so-called play between the washbasin main body and the fixed support pillars, when external force acts on the washbasin main body, there is a risk that the play causes a backlash phenomenon. is there.

If the washbasin body rattles when the washbasin body starts to move up or down, or when it stops moving, or when switching between up and down directions,
This may cause noise or, in extreme cases, overflow of water filled in the wash basin.

This invention was made in view of the above-mentioned circumstances, and its purpose is to prevent the rattling phenomenon at the start of elevating the washbasin body, etc. It is an object of the present invention to provide an elevator device for a wash basin, which is most suitable for use when it is configured to be able to move up and down.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the configuration of the lifting device for a washbasin according to the present invention comprises a pair of fixed struts standing on the left and right sides and a pair of fixed struts arranged in front of the pair of fixed struts. The fixed support column includes a washbasin main body that is connected to the support column via a plurality of rollers so as to be able to move up and down, and an actuator that is provided on the rear side of the washbasin system main body and that moves the washbasin table body up and down. A space to accommodate while having a gap,
And an opening through which a supporting shaft continuously connected to the roller is communicated with the space, and a pair of fixed columns have their openings opposed to each other. The upper and lower brackets are horizontally connected to each other through the support shaft, and the actuator has its upper end supporting shaft position relative to the main body of the washbasin above the supporting shaft position of the upper roller relative to the main body of the washbasin. It is characterized in that it is set rearward so as to be farther from the base body.

[Action]

Therefore, the washbasin body is continuously connected to a pair of fixed columns that are erected on the left and right sides on the back side through a plurality of rollers, that is, on the left and right sides on the back side via brackets and spindles. By accommodating the formed roller in each space of the pair of fixed columns with a gap, the rollers are linked to the pair of fixed columns so as to be able to move up and down.

At this time, since the center of gravity of the washbasin main body is originally at the front, the washbasin main body tends to lean forward.

As a result, in the space of the fixed strut, the upper roller is adjacent to the so-called front inner wall in a pressure contact tendency, and in the space of the fixed strut, the lower roller is in a pressure contact tendency to the opposite so-called inner wall. Be adjacent to.

Therefore, even if there is a gap in the portion where the roller is connected to the fixed column, a so-called rattling phenomenon due to the gap tends to be always prevented.

Then, when the washbasin body is raised by the operation of the actuator, the lifting force from the actuator acts on the rear position where it is separated from the washbasin body from the support shaft position of the roller. As it is raised while being maintained in the state, the rattling phenomenon does not occur.

Further, when the washbasin main body is lowered, the actuator is allowed to freely contract, so that the washbasin main body is lowered due to its own weight in the forward tilted state, and at this time, the rattling phenomenon does not occur.

〔Example〕

Hereinafter, the present invention will be described based on an illustrated embodiment.

As shown in FIGS. 1 and 2, a washbasin lifting device according to an embodiment of the present invention stands upright on both left and right rear sides which are the right side of the base 1 installed on the floor. The washing stand main body 3 is subordinately moved up and down to the pair of fixed columns 2, which are vertically installed.

In this embodiment, the pair of fixed columns 2, 2 are made of a mold material having a square C-shaped cross section, and each have a space 2a (see FIG. 2) for accommodating rollers 5a, 5b described later. At the same time, it has an opening 2b communicating with the space 2a and permitting insertion of a support shaft 6 which will be described later.

When the rollers 5a and 5b are housed in the space 2a, the roller 5a
Between the outer periphery of a and 5b and the so-called inner wall of the fixed support column 2, the roller 5
It is set so that some gap A that allows smooth rotation of a and 5b is formed.

Further, the opening 2b, in the pair of fixed columns 2, 2, are arranged so that they are opposed to each other,
Moreover, in this embodiment, it is formed over the entire length of the fixed column 2.

The washbasin main body 3 has a washbasin 3a on its upper surface side, and is horizontally stretched from the left and right upper and lower sides of its back surface, which is the right side in FIGS. 1 and 2. Left and right one-on-two brackets that are consecutively installed to extend
It has 4a and 4b.

Each of the upper and lower brackets 4a, 4b is rotatably attached to each roller 5a, 5b under the distribution of a support shaft 6 continuously provided at the tip thereof so as to penetrate the tip.
5b is a space 2 in the left and right fixed columns 2, 2
It is supposed to be present in a.

Therefore, the washbasin body 3 is subordinately moved up and down by the pair of fixed columns 2 and 2 while the rollers 5a and 5b are rolling, but at this time, the washstand body 3 is a so-called front side. Due to the structure including the wash-basin 3a that overhangs, the center of gravity of the wash-ball 3a is in the foreground, and it tends to fall forward.

As a result, the upper roller 5a is adjacent to the inner wall on the front side in a pressure contact tendency in the space 2a of the fixed strut 2, and the lower roller 5b is in the space 2a of the fixed strut 2 on the opposite side in the space 2a. It is adjacent to the inner wall on the side in a pressure welding tendency.

Therefore, while the washbasin main body 3 is accommodated in the space 2a of the fixed column 2 where the upper and lower rollers 5a, 5b have the gap A, it is connected to the fixed column 2 without so-called rattling. In addition, the fixed column 2 can be subordinately moved up and down.

On the other hand, in this embodiment, the washbasin main body 3 is said to be lifted and lowered by the expansion and contraction of an actuator 7 as an expansion and contraction mechanism such as a hydraulic cylinder. The actuator 7 is a hydraulic pressure supply / discharge source installed on the base 1. It is configured to expand and contract by controlling the supply and discharge of hydraulic oil from 10.

The lower end of the actuator 7 is pivotally supported by the base 1 via a bracket 8 (see FIG. 1), and the upper end thereof, that is, a rod 7a that is a member that appears and disappears when the hydraulic oil is supplied and discharged. The upper end (see FIG. 1) is pivotally supported via a bracket 9 at a position near the upper end on the back side of the washbasin body 3, that is, at a position above the upper bracket 4a.

The upper and lower ends of the actuator 7, in particular, the upper end of the actuator 7 is attached to the base 1 at a so-called rear position with respect to the upper roller 5a and the lower roller 5b, particularly the upper roller 5a. Is set to.

That is, the center position line of the support shaft 6 to which the upper roller 5a is attached
With respect to l1, the center position line l2 in the upper shaft support portion of the actuator 7 is set to be farther from the washstand main body 3.

Therefore, in the above-mentioned actuator 7, when the extension operation is performed, the upper end of the back portion of the washbasin body 3 is lifted upward, and thus the washstand body 3 is placed in the forward tilted state. It will be.

As described above, the washbasin main body 3 tends to fall forward while the upper and lower ends of the washbasin main body 3 are regulated by the fixed columns 2, so that the washbasin main body 3 is extended when the actuator 7 is extended. Therefore, even if the rollers 5a and 5b are connected to the fixed support column 2 with the gap A, the roller 3a rises to the fixed support column 2 without rattling. Become.

At this time, each of the rollers 5a, 5b has a gap A with respect to the surface on the opposite side of the rolling surface, so that the rolling is smoothly realized.

Further, when the actuator 7 is reversed from the extended state and placed in the contracted state, the washbasin body 3 is lowered by its own weight. Even at this time, the washstand body 3 itself tends to fall forward. It is set.

At this time, since the actuator 7 is allowed to freely contract, the washbasin body 3 is lowered while the frontward leaning state is maintained. Therefore, even in this descending state, the washstand body 3 is also lowered. Will be subordinate to the fixed support column 2 without rattling under the distribution of the rollers 5a and 5b.

The so-called initial speed control when the expansion / contraction operation of the actuator 7 is started and the direction thereof is switched is realized by, for example, a valve (not shown) in the hydraulic pressure supply / discharge source 10.

[Effect of device]

As described above, according to the present invention, when the washbasin body is connected to the fixed support via the upper and lower rollers, the upper and lower rollers are housed in the internal space of the fixed support with a gap. So, in combination with the center of gravity of the sink body,
The wash basin body will always be kept in a tendency to tip forward,
Even if the roller rolls, the phenomenon of rattling with the fixed column is not caused.

Further, according to the present invention, when the washbasin body connected to the fixed support via upper and lower rollers is moved up and down by the expansion and contraction operation of the actuator, the fulcrum position of the actuator with respect to the washstand main body is connected to the fixed support. Since it is set rearward from the fulcrum position of the washbasin main body, the external force action at the time of extension operation of the actuator acts in the same forward tilt tendency as when the washbasin main body stands still, As a result, it is possible to raise the washbasin main body without causing a rattling phenomenon between the upper and lower rollers and the fixed support.

When the actuator contracts, free contraction of the actuator is allowed, so that the weight of the washbasin body causes it to descend with the same tendency of tilting forward as when stationary. Therefore, it is possible to realize the lowering of the main body of the washbasin without causing a rattling phenomenon.

As a result, according to the present invention, the washbasin body does not rattle when the washbasin body starts to move up and down, when it stops moving up and down, or when switching the lifting direction.Therefore, there is no risk of noise due to the rattling phenomenon. The advantage is that it is possible to prevent the water filled in the wash bowl from overflowing due to vibration.
