Description

  The present invention relates to an elevating mechanism that elevates and lowers from a counter opening of a system kitchen or a vanity, and particularly relates to an elevating mechanism for a screen for preventing water and oil from scattering.

  A screen is usually set up in front of the stove in the face-to-face kitchen. This screen serves to prevent oil splashing during cooking from splashing to the opposite side. However, at times other than cooking, if the screen comes out from the viewpoint of transporting the cooked food, aesthetics, etc., it will be a hindrance, and the advantage of the face-to-face kitchen will be lost. Therefore, methods for raising and lowering the screen from the counter opening are disclosed in Japanese Patent Application Laid-Open No. 2008-246169, Japanese Patent Application Laid-Open No. 10-205782, and Japanese Patent No. 3461867.

  Japanese Patent Application Laid-Open No. 2008-246169 discloses a structure in which a screen is stored under a counter and is moved up and down by an electric motor. However, renovation requires a new power source, and a drive source and a power source are required under the counter. There are restrictions on installation. In addition, a drive source such as an electric motor and a device for controlling the electric motor are also required, resulting in an expensive lifting mechanism.

  Japanese Patent Laid-Open No. 10-205782 discloses a structure in which the user lifts the screen by hand. When a glass material is used as the screen, the weight is about 3.5 kg at 400 mm × 800 mm × t 4 mm, and the weight is hand-held. Lifting it with a heavy burden on the user. In addition, using fire on the stove can be dangerous.

  Japanese Patent No. 3461867 discloses a load reducing device using a spring that reduces the lifting and lowering of the screen, but even if it is a Conston spring that can expect a constant load, there is a variation in the urging force of the spring and a stable feeling of use is provided. Cannot be achieved. Here, the variation is considered to be a variation due to individual differences of the spring itself or a secular change. In addition, the spring has a peculiar creaking sound and is heavy at start-up, which makes the feeling of use worse.

It is a detailed sectional view around the opening 32 when the screen 50 is raised. It is a detailed sectional view around the opening 32 when the screen 50 is stored. It is a perspective view of the vanity table 110 which concerns on embodiment of this invention.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1 and FIG. 2, the system kitchen 10 of the present embodiment includes a cabinet 11, a counter 30 disposed on the cabinet 11, and a stove 12 that is a cooking utensil disposed on the counter 30. And a sink 13 which is also disposed on the counter 30. The counter 30 includes a counter extension 31 that extends rearward from the back decorative plate 14 of the cabinet 11. Further, a screen 50 is erected on the counter extension 31 behind the stove 12 and the sink 13. In addition, the counter extension 31 is provided with an opening 32 through which the screen 50 advances and retracts in order to store the screen 50 below the counter 30, and below the counter extension 31 and on the back decorative plate 14 of the cabinet 11. An elevating mechanism 70 having a storage space for the screen 50 and equipped with an elevating means for the screen 50 is disposed outside. The screen 50 is a part of the lifting mechanism 70.
In the present embodiment, an example in which the elevating mechanism 70 is provided outside the back decorative plate 14 of the cabinet 11 is shown, but the elevating mechanism 70 may be built in the cabinet 11 without providing the counter extension 31.

  Subsequently, as shown in FIGS. 3 and 4, the elevating mechanism 70 includes a base case 80 to which components are attached, a base case lid (not shown) that covers the base member, a screen 50, and left and right mains that guide elevating of the screen 50. Rail 71, connecting member 72 connecting screen 50 and main rail 71, wire hook 79 attached to connecting member 72 and capable of fixing a wire, wire 73 having one end fixed to wire hook 79, wire A weight 74 fixed to the other end of 73, a weight rail 75 for guiding the lifting and lowering of the weight 74, a pulley 76 around which the wire 73 is wound, and a storage holding means for holding the screen 50 in a storage state are fixed to the screen 50. A female latch 77a, and a male latch 77b fixed to the base case 80 as storage and holding means. A piston-type damper 78 that is fixed to the connecting member 72 and decelerates the rising speed before reaching the peak due to ascending to alleviate the impact, and a damper receiving portion 81 that a part of the base case 80 abuts against the tip of the damper 78 are provided. ing.

The screen 50 is a tempered glass 51, a screen upper frame 52 that protects the upper end of the outer periphery of the tempered glass 51 as a member that protects the end face of the tempered glass 51 with a substantially U-shape, and a screen horizontal frame 53 that protects the left and right ends. The screen 50 is fixed to the connecting member 72 at the lower left and right sides of the tempered glass 51.
As shown in FIG. 4, when the latch of the male side latch 77b is inserted into the mouth of the female side latch 77a and pushed to a certain extent, the latch 77 protrudes and the hook in the mouth of the female side latch 77a protrudes. I get caught in the claw and won't come off. Further, when pushed again in this state, the hook of the female side latch 77a is retracted, and the nail of the male side latch 77b is released to be removed. By this mechanism of the latch 77, the screen 50 is held in the retracted state.

  Here, the movable body A includes a screen 50, a wire hook 79, a connecting member 72, a female side latch 77a, and a damper 78. The weight of the movable body A is 4 kg. On the other hand, the weight of the weight 74 is slightly heavier than the movable body A. For example, the weight is set to 4.15 kg and the weight difference is set to 150 g. Therefore, the force is acting on the movable body A in the always rising direction. The reason for the weight difference 150g is that the user wants to reduce the force with which the user pushes the screen when descending, as will be described later, and overcomes the frictional resistance of the main rail 71, weight rail 75, and pulley 76, and the movable body A rises. And that the ascending speed of the movable body A does not give the user unpleasant feeling. In other words, if the weight difference between the weight 74 and the movable body A is too large, a large force is required for the user to push the screen when the weight 74 is lowered, and the screen 50 is raised quickly and gives the user a sense of fear. On the other hand, if the load difference is too small, the screen 50 does not rise against the frictional resistance of the main rail 71, the weight rail 75, and the pulley 76, and the rising speed of the screen 50 is slow, giving the user an unpleasant feeling.

FIG. 5 is a detailed cross-sectional view around the opening 32 when the screen 50 is raised. As shown in FIG. 5, the opening 32 has a guide for raising and lowering the screen 50, preventing rattling when the screen 50 is raised, and preventing water from entering the lifting mechanism 70 from the opening 32. A support member 33 is provided so as to cover the opening edge of the opening 32. The support member 33 is bonded to the contact surface with the opening 32 of the counter 30 with an adhesive so that a step of about 3 mm is formed above the upper surface of the counter 30, and the support member 33 and the counter 30 are in contact with each other. The contact portion has a configuration in which the liquid spilled on the counter 30 is difficult to enter the elevating mechanism 70 by processing the coking 35.
FIG. 6 is a detailed cross-sectional view around the opening 32 when the screen 50 is stored. As shown in FIG. 6, in the stored state of the screen 50, the upper end of the screen upper frame 52 is set to be substantially flush with the upper surface of the support member 33.
Further, as shown in FIG. 5, a counter reinforcing member 34 is attached to the back side of the counter 30 with an opening 32 secured. Further, the contact surface of the base case 80 with the counter reinforcing member 34 is formed to be bent upward and contact the opening end face of the opening 32. Thereby, the installation position of the screen 50 with respect to the opening part 32 can be determined.

Next, the operation and effect of the present invention will be described through the description of the usage scene of the system kitchen 10 and the lifting / lowering operation of the screen 50.
When cooking using the stove 12 or sink 13 of the system kitchen 10, the user pushes the screen upper frame 52 with his / her finger to raise the screen 50 in the retracted state shown in FIG. 4 or FIG. Then, the male side latch 77b is pushed into the mouth of the female side latch 77a fixed to the screen 50, and the latch is released. The pushing amount necessary for releasing the latch is about 2 mm. When the latch 77 is released and the user releases his / her hand, the weight 74 heavier than the movable body A side begins to descend slowly along the weight rail 75 due to the difference in weight, and is connected via the wire 73 wound around the pulley 76. The connecting member 72 and the screen 50 are projected along the main rail 71 above the counter extension 31 from the opening 32 and the support member 33. Thereafter, the screen 50 gradually increases in speed, and starts to decelerate when the tip of the damper 78 abuts against the damper receiving portion 81 just before reaching the apex. When the tip of the damper 78 is completely pushed, the screen 50 Stops in the state of FIG. 3 or FIG. Thus, the screen 50 can be raised as necessary.

  When cooking is completed and the screen 50 in the state shown in FIG. 3 or 5 is stored, when the user pushes the screen upper frame 52 downward, the movable body A including the screen 50 descends along the main rail 71. The weight 74 connected via the wire 73 wound around the pulley 76 rises along the weight rail 75. The pushing force of the user is about 150 g, which is the difference in weight between the movable body A and the weight 74, and the screen 50 can be started to descend with a hand. If the user continues to push the screen as it is and the screen upper frame 52 is substantially flush with the support member 33 as shown in FIG. 4 or FIG. 6, the base case 80 is fixed to the mouth of the female side latch 77a fixed to the screen 50. When the claw of the male side latch 77b is inserted and further pushed in by about 2 mm, the hook of the female side latch 77a protrudes and is caught by the claw of the male side latch 77b. Thereafter, when the hand is released, the screen 50 rises again by about 2 mm, and is held while the upper surface of the screen upper frame 52 and the support member 33 are substantially flush.

When liquid is spilled on the counter 30 in this stored state, the liquid is prevented from entering the lifting mechanism 70 by the 3 mm step between the support member 33 and the counter 30.

Also, as shown in FIG. 4 or FIG. 6, when a pan filled with hot water is placed on the support member 33 in the retracted state of the screen 50, the user pushes the screen upper frame 52 without noticing the pan. Even if the ascent starts, if the weight of the pan and hot water is heavier than the weight difference 150g between the weight 74 and the movable body A, the screen 50 will not rise. Therefore, the danger of spilling hot water by inadvertently turning over the pan can be avoided.

According to the present invention, the raised screen 50 can prevent oil from splashing when the stove 12 is used, and can also prevent water splashing from the sink 13. Further, when the stove 12 and the sink 13 are not cleaned up, the stove 12 and the sink 13 can be hidden from the living side. In addition, since the screen 50 prevents diffusion of odor, smoke, heat, etc. from the stove 12, it can be expected that the repairing power of the ventilation fan is improved. Further, when the screen 50 is stored under the counter 30, only 3 mm is present on the counter 30 as the upper end surface of the screen upper frame 52 and the protruding portion of the support member 33. It does not get in the way. Furthermore, in the face-to-face kitchen, by making it possible to store the screen 50, it is possible to maintain the aesthetics of the system kitchen 10 without sacrificing the open space that is the original merit.
Furthermore, in the operation, when it is lifted, it is lifted automatically only by releasing the latches 77a and 77b, and further, it decelerates just before reaching the peak due to the lift, and the impact is alleviated. There is no discomfort. At the time of descending, the user only applies a load of about 150 g to the screen 50, and the user descends almost with his / her hand, so there is almost no burden on the user.
Further, the weight of the weight 74 does not change over time and can maintain this operational feeling semipermanently.
In addition, if a pan is placed on the screen 50 and is lifted by mistake, the screen 50 will not rise if the weight difference between the movable body A and the weight 74 is about 150 g or more. The danger of spilling hot water can be avoided.

The second embodiment of the present invention will be described below with reference to the drawings.
FIG. 7 is a front perspective view of the vanity table 110 according to the embodiment of the present invention.

The vanity table 110 according to the present embodiment includes a cabinet 11, a counter 30 disposed on the cabinet 11, and a bowl 113 formed integrally with the counter 30. The counter 30 has screens 50 standing on both sides of the bowl 113. The counter 30 is provided with an opening 32 for moving the screen 50 up and down, and the cabinet 11 has a storage space for the screen 50 and a lifting mechanism 70 (not shown) on which the lifting means for the screen 50 is mounted. Has been. The screen 50 is a part of the lifting mechanism.
In the present embodiment, the lifting mechanism 70 in which the screen 50 is housed may be provided outside the cabinet 11 as in the first embodiment. In this case, the elevating mechanism 70 is provided on the side portion of the cabinet 11.

  The configuration of the elevating mechanism 70 is the same as in the first embodiment, and is omitted here. The weight difference between the movable body B including the screen 50 and the weight is about 150 g.

Next, the operation and effect of the present invention will be described through the use scene of the vanity table 110 and the description of the lifting operation of the screen 50.
When washing the face or washing the hair with the vanity table 110, the user pushes the upper part of the screen 50 with his / her finger to release the latch in order to raise the stored screen 50. When the user releases his / her hand from the upper part of the screen 50, the weight slowly descends due to the weight difference between the weight and the screen 50, and the screen 50 connected to the weight via the wire wound around the pulley is from the opening 32. It protrudes above the counter 30. Thereafter, the screen 50 gradually rises in speed, and stops while being decelerated by the damper mechanism just before reaching the top. In this way, the screen 50 is raised as necessary to perform face washing and hair washing.

  During face washing or shampooing, water often splatters outside the bowl 113, but the splashed water hits the raised screen 50, thus preventing the wall or floor outside the vanity 110 from getting wet with water.

  When face washing or hair washing is completed and the screen 50 is stored, the user pushes the screen 50 downward, the screen 50 is lowered, and the weight connected via the wire is raised. The pushing force of the user is about 150 g, which is a weight difference between the movable body B including the screen 50 and the weight, and the screen 50 can be started to descend with a hand. If the user continues to push the screen 50 and the upper end of the screen 50 is substantially flush with the opening 32 of the counter 30, the screen 50 is caught by the latch, and the upper end of the screen 50 and the opening 32 are held substantially flush. The

According to the present invention, the screen 50 prevents water from splashing on the wall or floor, and the screen 50 is stored under the counter 30, so that the upper end surface of the screen 50 is substantially flush with the counter 30 on the counter 30. It does not get in the way when the vanity table 110 is normally used. Furthermore, in the vanity table 110 with a wide counter 30, by allowing the screen 50 to be stored, it is possible to maintain the beauty of the vanity space without sacrificing the open space that is the original merit. Can do.
Furthermore, during the operation, when it is lifted, it is lifted automatically just by releasing the storage and holding means, and further, it decelerates before reaching the top of the lift to alleviate the impact, so there is almost no burden on the user and there is no problem during operation. There is no pleasure. At the time of descending, the user only applies a load of about 150 g to the screen 50, and the user descends almost with his / her hand, so there is almost no burden on the user.
Further, the weight of the weight does not change over time, and this feeling of operation can be maintained semipermanently.

In the above-described two embodiments, the weight of the weight is heavier than that of the movable body. However, the weight is not particularly limited, and the weight may be the same or the movable body side may be slightly heavier. In this case, in order to raise the screen, the user must intentionally lift the screen by hand, and even if a pan with hot water or a glass cup is placed on the screen, it is not possible. The screen is lifted up and the object is not turned over. In this case, the force for lifting the screen is the weight difference between the movable body and the weight, and can be lifted with a slight force. Further, when the movable body side is made heavy, it is preferable to change the place where the latch is provided and use it as a raising and holding means for holding the movable body at the raised position.
Further, the damper functions at the time of ascent, but it may function at the time of descent or both. The feeling of operation is further improved because the impact when descent is eased.
Further, it is more preferable that the weight 74 has a structure capable of adjusting the weight. For example, a structure in which an additional weight can be fixed with a screw or the like is preferable. By doing so, the weight error of the tempered glass used for the screen can be absorbed, and more stable operation can be secured on site. In addition, slight errors in frictional resistance of the main rail, weight rail and pulley can be absorbed.

  In the above two embodiments, the weight of the movable body is 4 kg, the weight is 4.15 kg, and the weight difference is 150 g. However, the weight of the movable body and the weight and the weight difference between the movable body and the weight are It can be changed freely according to the form. It may be set to an appropriate value in consideration of the friction resistance of the main rail, the weight rail and the pulley, and the setting of the rising or falling time that can be comfortably used by the user.

Further, in the above two embodiments, only a fixed fixed pulley is used, and the weight and the moving amount of the movable body and the weight are substantially the same. Good. By using the moving pulley, for example, it is possible to reduce the weight of the weight or increase the stroke of the movable body.
In the above-described two embodiments, the wire is used to suspend the weight and the movable body. However, the present invention is not particularly limited to this, as long as it can be used through a pulley such as a belt or a chain.

In the above two embodiments, the movable body is a screen. However, if the weight on the movable body side is relatively constant during elevation, this elevation mechanism can be used. For example, shelves having a storage function such as a mirror of a vanity, a knife insert that raises and lowers from a counter, and a toothbrush holder can be considered.
In addition, other points can be freely changed as long as they do not depart from the scope of the present invention.
