Description

The present invention relates to a frame body and a bathtub stand.

2. Description of the Related Art Conventionally, there has been known a bathtub stand that is used as a stepping stool, a seat, or the like in a washing area of a bathroom or in a bathtub. Generally, a bathtub base includes a base and a plurality of support legs that support the base. The base has a frame body provided by connecting the upper ends of the support legs, a seat supported by the frame, and a seat laid on the upper surface of the seat. (See, for example, Patent Document 1).

There are a plurality of types of seat cushions, such as a cushion seat made of a cushioning material and a rubber seat made of a rubber material. For example, if the seat is a cushion seat, the seating comfort can be improved when the base is used as a seat. Moreover, when the seat surface sheet is a rubber sheet, it can be used as a non-slip when using the platform as a step.

JP-A-2003-125966

By the way, since the cushion seat tends to contain air inside, when the bathtub stand having the cushion seat is submerged in the bathtub for use, it is conceivable that the bathtub stand receives a relatively large buoyancy. For this reason, it is considered desirable to increase the weight of such a bathtub stand in order to make it easier to sink in the bathtub.

On the other hand, the rubber seat is less likely to trap air inside than the cushion seat. Therefore, it is considered that when a bathtub base having a rubber sheet is submerged in a bathtub and used, the bathtub base does not receive a large buoyancy force. For this reason, it is considered that such a bathtub stand does not need to be so heavy.

As described above, it is conceivable that the weight required for a bathtub stand varies depending on the type of seat surface sheet used. Therefore, it is thought that the weight of the bathtub stand will be individually set according to the required weight. In addition, since the weight of the frame body accounts for a large proportion of the weight of the bathtub stand, in this case, it is considered that the weight of the frame body will be set individually.

However, if the weight of the frame body is individually set for each required weight, a plurality of frame bodies having different weights will be generated. In this case, since each of the plurality of frame bodies is manufactured individually, problems such as an increase in the manufacturing cost of the frame bodies may occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a frame body and a bathtub stand that can obtain effects such as reduction in manufacturing cost.

In order to solve the above-mentioned problems, a frame body of a first invention is a frame body for constituting the platform in a bathtub platform comprising a platform and a plurality of supporting legs for supporting the platform from below. The frame body is a molding made of a metal material, and has a plurality of punched parts that can be punched out by a punching process. It is characterized in that a rupture portion that is ruptured during the punching process is formed, and that the punched portion can be punched by breaking the rupture portion.

According to the present invention, a plurality of punched portions that can be punched out are provided in a frame body formed of a metal material. In this case, for example, it is possible to obtain a light frame body by punching out all the punched parts of the frame body, or to obtain a heavy frame body by punching part of the punched parts out of the punched parts. can. Therefore, in this case, by adjusting the number of punched portions to be punched, it is possible to obtain a plurality of types of frame bodies with different weights. With such a configuration, when a plurality of frame bodies having different weights are manufactured, a common frame body can be used as a base for manufacturing, so that effects such as a reduction in manufacturing cost can be obtained.

In addition, since the frame body is provided with a plurality of punched portions, the opening area after the punched portions are punched out can be made smaller compared to the case where only one punched portion is provided, for example. This makes it easier to secure the strength of the frame body after the punched portion is punched out.

A frame body of a second invention is the frame body of the first invention, wherein the frame body has a rectangular shape in a plan view, and a plurality of the punched parts are provided symmetrically with respect to the central portion of the frame body. It is characterized by having a portion.

According to the present invention, as the punched portion, a plurality of punched portions are provided symmetrically with respect to the central portion of the frame body which is rectangular in plan view. In this case, it is possible to suppress the weight balance of the frame body from changing depending on whether the plurality of punched portions are punched together and when they are not punched. As a result, a configuration suitable for manufacturing a plurality of frame bodies having different weights based on a common frame body can be obtained.

A frame body according to a third aspect of the invention is the frame body according to the second aspect, wherein the frame body includes an outer frame portion formed in a rectangular frame shape in a plan view, and an outer frame portion extending along a diagonal line of the outer frame portion. A pair of diagonal frame portions that are connected to the outer frame portion and are connected to each other in a state of crossing each other; each corner of which is connected to the diagonal frame portion, and the frame body includes the diagonal frame portions and the A plurality of partitioned regions partitioned by the inner frame portion are formed, and the punched portion is provided for each partitioned region.

According to the present invention, since the frame body has a pair of diagonal frame parts extending along the diagonal lines of the outer frame part in addition to the rectangular frame-shaped outer frame part, the strength of the frame body can be improved. can be done. The frame body further has a rectangular frame-shaped inner frame portion, and the inside of the outer frame portion is partitioned into a plurality of regions by the inner frame portion and the diagonal frame portions. A punched portion is provided for each of the plurality of partitioned areas. In this case, since a large number of punched portions can be provided by dividing the punched portions into small pieces, the degree of freedom of adjustment can be increased when adjusting the weight of the frame body by punching the punched portions.

A bathtub stand according to a fourth aspect of the invention comprises the stand and a plurality of the support legs that support the stand from below, and the stand is the first support leg connected to the upper side of each of the support legs. It has a frame body, a seat supported by the first frame, and a first seat laid on the upper surface of the seat, wherein the first seat is made of a cushioning material. wherein the first frame body is the frame body of any one of the first to third inventions, wherein at least some of the punched parts are left unpunched. It is characterized by being a frame body.

In the bathtub stand of the present invention, the seat is formed of a cushioning material. Since the cushion material tends to contain air inside, it is considered that the buoyant force that the bathtub base receives when the bathtub base is submerged in the bathtub increases. Therefore, it is considered necessary to increase the weight of the bathtub stand so that the bathtub stand can be easily submerged.

In this regard, in the present invention, as the first frame body constituting the base portion, at least a part of the punched portions of the frame body of the first invention is left unpunched. A frame is used. In this case, since a relatively heavy frame body is used as the first frame body, it is possible to obtain a relatively heavy bathtub stand.

A bathtub stand according to a fifth aspect of the present invention includes the stand and a plurality of the support legs that support the stand from below, and the stand is a second body provided in connection with the upper side of each of the support legs. It has a frame body, a seat portion supported by the second frame body, and a second seat surface sheet laid on the upper surface of the seat portion, wherein the second seat surface sheet is made of a rubber material for preventing slipping. wherein the second frame body is a frame body in which all of the punched portions of the frame body of any one of the first to third inventions are punched out It is characterized by

In the bathtub stand of the present invention, the seat surface sheet is made of a rubber material. Since the rubber material is less likely to contain air than the cushion material, it is considered that the bathtub base does not receive a large buoyancy force when the bathtub base is submerged in the bathtub. Therefore, it is considered that such a bathtub stand does not need to be so heavy.

In this regard, in the present invention, the frame body of the first invention in which all of the punched portions are punched out is used as the second frame body constituting the base portion. In this case, since a relatively light frame body is used as the second frame body, it is possible to obtain a bathtub stand that is not so heavy.

An embodiment embodying the present invention will be described below with reference to the drawings. In this embodiment, two types of bathtub stands are assumed as the bathtub stands. These bathtub stands are the first bathtub stand 10 and the second bathtub stand 20, respectively, and below, the basic structure of each of these bathtub stands 10 and 20 is demonstrated in order.

First, the configuration of the first bathtub stand 10 will be described with reference to FIG. FIG. 1 is a perspective view of the first bathtub stand 10 as seen obliquely from above. The first bathtub stand 10 corresponds to the "bathtub stand" recited in claim 4 in the scope of claims.

As shown in FIG. 1, the first bathtub base 10 includes a base 11 and a plurality of (specifically, four) support legs 12 that support the base 11 from below. The base portion 11 has a rectangular shape in plan view, and supporting legs 12 are arranged at the four corners of the base portion 11 .

The base portion 11 includes a frame body 13 connected to the upper end side of each support leg 12, a seat portion 14 supported by the frame body 13, and a seat surface sheet laid on the upper surface of the seat portion 14. 15. The frame body 13 is made of an aluminum alloy and has a rectangular shape in plan view. Note that the frame body 13 corresponds to the first frame body.

The seat portion 14 is formed of a synthetic resin material and includes a top plate portion 14a which is rectangular in plan view and covers the frame body 13 from above, and a side plate extending downward from the peripheral edge portion of the top plate portion 14a and covering the frame body 13 from the sides. and a portion 14b. The seat 15 is made of a cushioning material, and the upper surface of the seat 15 forms a seat. Thereby, in the first bathtub stand 10, the comfort of sitting on the seat portion 14 of the user is improved. Note that the seat 15 corresponds to the first seat.

Each support leg 12 has a tubular shape extending vertically. A leg rubber 17 is attached to the lower end of each support leg 12 .

Next, the second bathtub base 20 will be described with reference to FIG. FIG. 2 is a perspective view of the second bathtub stand 20 as seen obliquely from above. The second bathtub stand 20 corresponds to the "bathtub stand" recited in claim 5 in the scope of claims.

As shown in FIG. 2 , the second bathtub base 20 basically has the same configuration as the first bathtub base 10 and has the same external size as the first bathtub base 10 . The second bathtub base 20 also includes a base 21 and a plurality of support legs 22 that support the base 21 from below.

The base portion 21 includes a frame body 23 connected to the upper end side of each support leg 22, a seat portion 24 supported by the frame body 23, and a seat surface sheet 25 laid on the upper surface of the seat portion 24. and The frame body 23 is made of an aluminum alloy and has a rectangular shape in plan view. Note that the frame body 23 corresponds to the second frame body.

The seat portion 24 is formed of a synthetic resin material, and includes a top plate portion 24a that is rectangular in plan view and covers the frame body 23 from above, and a side plate that extends downward from the peripheral edge portion of the top plate portion 24a and covers the frame body 23 from the sides. and a portion 24b. Moreover, the seat surface sheet 25 is formed of a non-slip rubber material, and the upper surface of the seat surface sheet 25 forms a seat surface. Thereby, in the second bathtub stand 20, it is possible to prevent the user from slipping on the seat portion 24 when the user uses the second bathtub stand 20 as a step. Note that the seat 25 corresponds to the second seat.

Each support leg 22 has a tubular shape extending vertically. A leg rubber 27 is attached to the lower end of each support leg 22 .

Here, as described above, a cushion sheet is used as the seat surface sheet 15 in the first bathtub stand 10 . Since the cushion seat easily contains air inside, it is conceivable that the first bathtub base 10 receives a large buoyant force when the first bathtub base 10 is submerged in the hot water of the bathtub. Therefore, it is considered necessary to increase the weight of the first bathtub base 10 in order to facilitate sinking in the bathtub.

On the other hand, in the second bathtub base 20 , a rubber sheet is used as the seat surface sheet 25 . Since a rubber sheet does not easily contain air inside compared to a cushion sheet, it is conceivable that the buoyancy received by the second bathtub base 20 when the second bathtub base 20 is submerged in the bathtub is not so large. . Therefore, it is considered that the weight of the second bathtub stand 20 does not have to be increased so much.

As described above, the first bathtub stand 10 and the second bathtub stand 20 require different weights. requires a relatively low weight. Therefore, in this embodiment, the frame 13 of the first bathtub stand 10 is relatively heavy, and the frame 23 of the second bathtub stand 20 is relatively light. ing.

By the way, if each frame body having a different weight is individually manufactured, it is conceivable that the number of types of frame bodies increases, causing problems such as an increase in manufacturing cost. Therefore, in this embodiment, in view of such a point, the frame bodies 13 and 23 of the respective bathtub stands 10 and 20 are manufactured using a common frame body. That is, when manufacturing the frame bodies 13 and 23, first, the base frame body 30, which is the base for each of the frame bodies 13 and 23, is formed by aluminum die casting. are punched out to manufacture the frame bodies 13 and 23. In this punching process, the frame bodies 13 and 23 having different weights are manufactured by adjusting the size of the punched portion punched out from the base frame body 30 .

Next, the manufacturing flow of each frame body 13, 23 manufactured in this manner will be described in detail. First, the configuration of the base frame body 30 that serves as the base of each of the frame bodies 13 and 23 will be described with reference to FIGS. 3 to 6. FIG. 3 is a perspective view of the base frame body 30 as viewed obliquely from above, and FIG. 4 is a perspective view of the base frame body 30 as viewed obliquely from below. 5 is a plan view showing the base frame body 30, and FIG. 6 is a bottom view.

The base frame body 30 is a molded product formed by die casting (so-called aluminum die casting) using an aluminum alloy as a material. As shown in FIGS. 3 to 6, the base frame body 30 has a rectangular shape in plan view, more specifically, a rectangular shape. The base frame body 30 includes an outer frame portion 31 formed in a rectangular frame shape in a plan view, a pair of diagonal line frame portions 32 extending along respective diagonal lines of the outer frame portion 31, and an inner side of the outer frame portion 31. and an inner frame portion 33 formed in a rectangular frame shape. Note that the base frame body 30 corresponds to the "frame body" described in the claims.

The outer frame portion 31 has a rectangular shape and has four (four sides) frame side portions 35 and four cylindrical portions 36 provided at the four corners. Each tubular portion 36 has a tubular shape extending vertically, and connects adjacent frame side portions 35 to each other. Further, each cylindrical portion 36 serves as a leg attachment portion to which the support leg 12 is attached by inserting the upper end side of the support leg 12 .

Both ends of each diagonal frame portion 32 are connected to the outer frame portion 31, respectively, and more specifically, each diagonal frame portion 32 is connected to each cylindrical portion 36 positioned diagonally to each other. Each diagonal frame portion 32 is connected at an intersection portion 37 that intersects with each other, and the intersection portion 37 is located in the center of the outer frame portion 31 .

The inner frame portion 33 has a rectangular frame shape similar to the outer frame portion 31 and is smaller in size than the outer frame portion 31 . The inner frame portion 33 is formed so as to surround the intersection portion 37 , and its central portion is located at the same position as the intersection portion 37 . Therefore, the central portion of the inner frame portion 33 is positioned at the same position as the central portion of the outer frame portion 31 . Also, the inner frame portion 33 is connected to the diagonal frame portion 32 at each corner.

In the following, the outer frame portion 31, the diagonal frame portion 32 and the inner frame portion 33 are also collectively referred to as the frame portions 31-33.

In the base frame body 30 , a plurality of (specifically, eight) partitioned regions 39 partitioned by the diagonal frame portions 32 and the inner frame portion 33 are formed inside the outer frame portion 31 . Each partitioned region 39 is provided with a punched portion 42 that can be punched by punching. Each punched portion 42 can be punched individually by punching using a press.

Each punched portion 42 is formed to have a predetermined thickness, and is provided so as to straddle the frame portions 31 to 33 arranged around the punched portion 42 . Further, the top surface of each punched portion 42 is set at a height position substantially equal to that of the top surfaces of the frame portions 31 to 33 . 4 and 6, each punched portion 42 is shown with dot hatching.

A thin portion 45 having a smaller thickness than the punched portion 42 is provided at the boundary between the punched portion 42 and the frame portions 31 to 33 adjacent to the punched portion 42 . The thin portion 45 extends along the boundary between the punched portion 42 and the frame portions 31-33 to connect them to each other. In this case, the thinned portion 45 extends along the periphery of the punched portion 42 . The thin portion 45 is arranged at the upper end portion of the boundary between the punched portion 42 and the frame portions 31-33.

The thin portion 45 is a breaking portion (hereinafter referred to as a breaking portion 45) that is broken when the punched portion 42 is punched. During the punching process, the punched portion 42 is punched out by breaking the breaking portion 45 . A groove may be formed in the breaking portion 45 along the breaking portion 45 so that the breaking portion 45 can be easily broken.

Each punched portion 42 includes a plurality of (specifically, four) inner punched portions 42A to 42D provided inside the inner frame portion 33 and a plurality of (specifically, four) provided outside the inner frame portion 33. 4) outer stamped portions 42E-42H. Each of the inner punched portions 42A-42D has a triangular shape in plan view. A pair of inner punched portions 42A and 42B arranged in the long side direction of the base frame body 30 with the intersecting portion 37 therebetween and the intersecting portion 37 in the short side direction of the base frame body 30 are formed in each of the inner punched portions 42A to 42D. A pair of sandwiched inner stamped portions 42C, 42D are included.

The pair of inner punched portions 42A and 42B are formed symmetrically with respect to the intersection portion 37 (in other words, the central portion of the base frame body 30). The pair of inner punched portions 42C and 42D are also formed symmetrically with respect to the crossing portion 37. As shown in FIG. Also, the inner stamped portions 42A, 42B are larger in volume than the inner stamped portions 42C, 42D, and therefore are heavier.

Each of the outer punched portions 42E to 42H has a rectangular shape in plan view. Each of the outer punched portions 42E to 42H has a pair of outer punched portions 42E, 42F aligned in the long side direction of the base frame body 30 and a pair of outer punched portions 42G, 42H aligned in the short side direction of the base frame body 30. include. The pair of outer punched portions 42E and 42F are formed symmetrically with respect to the crossing portion 37. As shown in FIG. The pair of outer punched portions 42G and 42H are also formed symmetrically with respect to the crossing portion 37. As shown in FIG.

Next, each frame body 13, 23 of the first bathtub stand 10 and the second bathtub stand 20 manufactured using the base frame body 30 described above will be described. 7A is a bottom view showing the frame body 13 of the first bathtub stand 10, and FIG. 7B is a bottom view showing the frame body 23 of the second bathtub stand 20. FIG. First, the frame body 13 of the first bathtub stand 10 will be described.

As shown in FIG. 7A, when manufacturing the frame body 13 of the first bathtub stand 10 from the base frame body 30, out of the punched parts 42 of the base frame body 30, each outer punched part 42E to 42H is formed. and the pair of punched portions 42C and 42D are punched out by punching. As a result, only the pair of punched portions 42A and 42B of the punched portions 42 remains in the base frame body 30. As shown in FIG. The base frame body 30 in such a state is used as the frame body 13 of the first bathtub stand 10 . In this case, a relatively heavy frame body can be obtained as the frame body 13 of the first bathtub stand 10 .

Next, the frame body 23 of the second bathtub base 20 will be described.

As shown in FIG. 7(b), when manufacturing the frame body 23 of the second bathtub stand 20 from the base frame body 30, the punched portions 42A to 42H of the base frame body 30 are all punched out. As a result, the base frame body 30 is in a state in which all of the punched portions 42 are punched out (removed). The base frame body 30 in such a state is used as the frame body 23 of the second bathtub stand 20 . In this case, it is possible to obtain a relatively light frame body as the frame body 23 of the second bathtub stand 20 .

According to the configuration of the present embodiment described in detail above, the following excellent effects are obtained.

A base frame body 30 is formed by molding of an aluminum alloy (that is, aluminum die casting), and a plurality of punched portions 42 are provided on the base frame body 30 by punching. In this case, for example, by punching all of the punched portions 42 of the base frame 30, a light frame (specifically, the frame 23 of the second bathtub stand 20) can be obtained, or one of the punched portions 42 can be obtained. By punching out the punched part 42 of the part, a heavy frame body (specifically, the frame body 13 of the first bathtub stand 10) can be obtained. Therefore, in this case, by adjusting the number of punched portions 42 to be punched, it is possible to obtain a plurality of types of frame bodies with different weights. With such a configuration, when manufacturing a plurality of frame bodies having different weights, the common frame body (base frame body 30) can be used as a base, so that effects such as reduction in manufacturing cost can be obtained. .

In addition, since the base frame body 30 is provided with a plurality of punched portions 42, the opening area after the punched portions are punched out can be made smaller than, for example, when only one punched portion is provided. can. This makes it easier to ensure the strength of the frame bodies 13 and 23 after the punched portions are punched out.

As the punched portions 42, a plurality of punched portions 42 are provided symmetrically with respect to the central portion of the base frame body 30 which is rectangular in plan view. For example, the punched portion 42A and the punched portion 42B are provided symmetrically with respect to the central portion of the base frame body 30. As shown in FIG. In this case, the plurality of symmetrically provided punched portions 42A and 42B are punched together (specifically, when the frame body 23 is manufactured) and not punched (specifically, when the frame body 13 is manufactured). ), it is possible to prevent the weight balance of the frame body from changing. As a result, a configuration suitable for manufacturing a plurality of frame bodies 13 and 23 having different weights based on a common frame body (base frame body 30) can be obtained.

Since the base frame body 30 has a pair of diagonal line frame parts 32 extending along the diagonal line of the outer frame part 31 in addition to the rectangular frame-shaped outer frame part 31, the strength of the base frame body 30 is improved. be able to. Further, since the base frame body 30 further includes the rectangular inner frame portion 33, the strength of the base frame body 30 can be further improved.

Further, with the base frame body 30 configured as described above, the inside of the outer frame portion 31 is partitioned into a plurality of partitioned regions 39 by the inner frame portion 33 and the diagonal frame portions 32 . A punched portion 42 is provided for each of the plurality of partitioned regions 39 . In this case, since a large number of punched portions 42 can be divided into small pieces in the base frame body 30, the degree of freedom in adjusting the weight of the frame body by punching the punched portions 42 can be increased.

In addition, by dividing the punched portion 42 into small pieces, the opening area after the punched portion 42 is punched can be greatly reduced, so that the strength of the frame bodies 13 and 23 after the punched portion 42 is punched is reduced. It can be suitably secured.

The present invention is not limited to the above embodiments, and may be implemented as follows, for example.

- In the above-described embodiment, the punched portion 42 is provided for each partitioned region 39 of the base frame body 30 , but the punched portion 42 may be provided only for a part of each partitioned region 39 . For example, it is conceivable to provide the punched portions 42 (that is, inner punched portions 42A to 42D) only in each of the partitioned regions 39 inside the inner frame portion 33 . In this case, it is conceivable to form an opening region in advance in each partitioned region 39 on the outside of the inner frame portion 33 when the base frame body 30 is molded. By doing so, when manufacturing the frame bodies 13 and 23 of the bathtub stands 10 and 20 from the base frame body 30 by punching, the outer punched portions 42E to 42G do not need to be punched.

- The configuration of the base frame body 30 is not necessarily limited to that of the above embodiment. For example, in the above-described embodiment, the diagonal frame portion 32 is provided in the base frame body 30 in order to improve the strength of the base frame body 30. Instead of the diagonal frame portion 32, another frame portion is provided. good too. For example, a pair of intersecting frame portions extending in the long side direction and the short side direction of the outer frame portion 31 and crossing each other are provided inside the outer frame portion 31, and both ends of each of the intersecting frame portions are connected to the outer frame portion 31 respectively. A configuration of connecting to In this case, the intersecting portion where the intersecting frame portions intersect is positioned at the center of the outer frame portion 31 . Further, each crossing frame portion is further connected to the inner frame portion 33 at the crossing portion with the inner frame portion 33 .

Also in this configuration, the base frame body 30 is formed with a plurality of partitioned regions inside the outer frame portion 31, which are partitioned by the inner frame portion 33 and the crossing frame portions. Specifically, like the base frame body 30 of the above embodiment, eight partitioned areas are formed. Therefore, it is possible to provide a plurality of punched portions for each of these divided regions.

In the above embodiment, when manufacturing the frame body 13 of the first bathtub stand 10, out of the punched parts 42A to 42H of the base frame body 30, only the inner punched parts 42A and 42B remain. When manufacturing the frame body 23 of the second bathtub stand 20, all of the punched portions 42A to 42H were punched out. , which of the punched portions 42 should be left may be appropriately determined according to the weight required for the frame body to be manufactured.

For example, when manufacturing a frame body that is heavier than the frame body 13 of the first bathtub stand 10, only the outer punched parts 42E to 42H are punched out of the punched parts 42A to 42H, so that all the inner punched parts 42A to 42H are punched out. It is conceivable to manufacture a frame body in which 42D remains. Furthermore, when manufacturing a heavy frame body, only some of the outer punched parts 42E and 42F are punched out of the punched parts 42A to 42H, so that all the inner punched parts 42A to 42D and some of the inner punched parts 42A to 42D are punched out. It is conceivable to manufacture the frame body with remaining outer stamped portions 42G, 42H.

Note that a frame body in which all the punched portions 42A to 42G remain without being punched (that is, the base frame body 30 itself) may be used.

- In the above embodiment, the base frame body 30 is made of an aluminum alloy, but the base frame body 30 may be made of a metal material other than an aluminum alloy.
