Description

Obstacles

[0001] The present invention relates to an obstacle that can be installed in an indoor space, and more particularly to an obstacle that forms a gap between the indoor space and the obstacle, which prevents babies and young children from passing through but allows self-propelled equipment to pass through.

[0002] Because infants and small children lack common sense, they need to be kept away from dangerous rooms and areas such as kitchens, bathrooms, etc. For this purpose, there are products that are obstacles in the form of barriers or doors that can be installed and used, and these are known under names such as baby gates, baby fences, safety gates, safety fences, and playpens, as described in the following Patent Documents 1, 2, and Non-Patent Documents 1 and 2.

[0003] For example, among the products based on the prior art, a product called a baby gate is a door that is fixed by bracing against the sides. The main structure is made of hollow aluminum alloy material, with two pillars facing each other on each side and a crosspiece between them. These pillars and crosspieces are firmly connected by welding.

[0004] On the opposing sides of each pillar, there is a mechanism that uses a bolt and nut to brace the sides. This mechanism consists of an unthreaded hole drilled horizontally in the floor, into which a bolt with two nuts is inserted. The nut on the wall side provides a wide contact surface to prevent damage to the wall, and the nut on the pillar side opens up the gap between the two nuts when tightened, thereby bracing both sides. This bracing force is supported by a crosspiece that is in contact with the floor, fixing the central structure to a doorway, passageway, etc.

[0005] In addition, a door made of boards attached to a wooden frame is fixed to the central structure to prevent passage. One side of the door is fixed to a pillar with two double hinges. The other side of the door is equipped with an openable latch attached to the door itself on the pillar side. This has a small latch built into the inside of the door, which can be pushed out by a sliding mechanism at the top and inserted into a hole on the pillar side to change the open / close state.

[0006] On the other hand, self-propelled devices such as robot vacuum cleaners have become popular in recent years, and are known by product names such as Roomba (registered trademark) and Rulo (registered trademark), as described in the following non-patent documents 3 and 4.

[0009] The conventional obstacles mentioned above also obstruct the passage of self-propelled devices when they are not designed to allow infants to pass through. Therefore, when using self-propelled devices, it is necessary to make them suitable for infants to pass through.

[0010] The present invention provides an obstacle that can be installed in an indoor space such as a passageway, which is safe and does not obstruct the passage of self-propelled equipment even when infants are not allowed to pass through.

[0011] In order to solve the above problem, one embodiment of the obstacle of the present invention is an obstacle installed in an indoor space, and is characterized in that it comprises a shielding plate and a pair of posts that sandwich the shielding plate and have the shielding plate fixed to at least one of them, the posts extending parallel to the direction of gravity, and a gap is formed between the end of the shielding plate and the indoor space so that a self-propelled device smaller than an infant can pass through.

[0012] According to the present invention, an obstacle that can be installed in an indoor space such as a passageway to prevent infants from passing through can be given the function of not obstructing the passage of self-propelled equipment without impairing its function or causing any danger when used.

(c) A perspective view of an obstacle 800 according to an eighth embodiment of the present invention.

[0014] Hereinafter, embodiments of the present invention will be described in detail, but the present invention is not limited to these.

[0015] 1A is a perspective view of an obstacle 100 (hereinafter simply referred to as "obstacle") according to a first embodiment of the present invention. The obstacle 100 includes a shielding plate 120 and a pair of support posts 130 that sandwich the shielding plate 120. The support posts 130 extend parallel to the direction of gravity, and the obstacle 100 is fixed to an indoor space (not shown) by fixing means 140 provided on the support posts 130.

[0016] In this embodiment, a gap P1 is provided between the lower end 122 of the shielding plate 120 and the floor, allowing the self-propelled equipment to pass through. Also, a crosspiece 132 is provided between the end of the support 130 that contacts the floor, contributing to fixing the obstacle 100. Each component will be described in detail below.

[0017] The shielding plate 120 is a plate for preventing the baby from moving.

[0018] The shielding plate 120 can be made of wood, resin, or metal such as aluminum or an aluminum alloy. As long as the strength is sufficient, all or part of the shielding plate 120 may be solid or may have a hollow structure. Even when a low-strength material is used, sufficient strength may be obtained by introducing a reinforcing structure such as a diagonal brace. Furthermore, a cushioning material may be provided on the surface of the shielding plate 120 to enhance safety.

[0019] The shielding plate 120 may be in the shape of a fence or net, as well as a plate, as long as it prevents an infant from passing through. In this case, the gaps in the fence or net are large enough to prevent an infant from passing through.

[0020] The support pillar 130 is a member that holds the shielding plate 120 and extends parallel to the direction of gravity. The shielding plate 120 is connected to the support pillar 130 by a connecting means 150. In this embodiment, the connecting means 150 may be a movable member such as a hinge. This allows the obstacle 100 to be used as a single-leaf door. A stopper (not shown) may also be provided to prevent the obstacle 100 from accidentally opening or closing. For example, a small latch may be built into the door, and the latch may be pushed out by a sliding mechanism at the top and inserted into a hole on the pillar side to change the open / close state.

[0021] The support pillars 130 can be made of the same material as the shielding plate 120. For example, if they are made of hollow aluminum alloy material (pipes), they can be made lightweight while maintaining their strength.

[0022] In this embodiment, crosspieces 132 are provided between the ends of the support posts 130 that contact the floor. The crosspieces 132 maintain a specific distance between the support posts 130 while absorbing the force applied to the support posts 130 from the fixing means 140, which will be described later. The support posts 130 and the crosspieces 132 are firmly connected by, for example, welding. Furthermore, the crosspieces 132 increase the contact area of ​​the obstacle 100 with the floor, contributing to the installation stability of the obstacle 100. Meanwhile, as will be described later, the self-propelled equipment passes over the crosspieces 132, so the thickness (height) of the crosspieces 132 must be thick enough to allow the self-propelled equipment to climb over them.

[0023] The support 130 is fixed to an indoor space by a fixing means 140. The indoor space to which the support 130 is fixed may be, for example, a wall of a passageway or an entrance.

[0024] The fixing means 140 may be any mechanism capable of fixing the support 130, which holds the shielding plate 120, to an indoor space. For example, the fixing means 140 may be a mechanism (pole-type device) for bracing the support 130 to the side using a bolt and nut, or may be provided facing the wall to which each support 130 is attached. This mechanism involves drilling an unthreaded hole horizontally in the floor and inserting a bolt with two nuts through it. The nut on the wall side provides a wide contact surface to prevent damage to the wall, while the nut on the pillar side is tightened to widen the gap between the two nuts, thereby bracing the support 130 to both sides. This bracing force is supported by the crosspiece 132 that contacts the floor, thereby fixing the support 130 to a doorway, passageway, etc.

[0025] In this embodiment, a gap P1 is provided between the lower end 122 of the shielding plate 120 and the floor, allowing a self-propelled device smaller than a baby to pass through. Note that, although the arrow indicates the passage of the self-propelled device in the figure, the self-propelled device does not move only in that direction, but can pass through the gap P1 from either direction.

[0026] The height of the gap P1 is determined based on the dimensions of the self-propelled device to be passed through and the possibility of infants passing through. The dimensions of the self-propelled device to be passed through are obtained from information from each manufacturer and actual measurements of the device.

[0027] On the other hand, the gap width for infants and young children is determined based on the standards of public institutions, industry organizations, etc. of each country, as well as actual measurements. For example, for products intended for the Japanese market, the gap width can basically be determined based on the test methods in Non-Patent Document 5. For products intended for use in Europe and other regions, the gap width can be determined based on the test methods in Non-Patent Document 6.

[0028] As one embodiment, a method for determining the gap width based on the method described in Non-Patent Document 5 will be described. First, based on the test method and confirmation method described in Section 4.3.5.1 b) of Non-Patent Document 5, which assumes entry from the head direction, it is confirmed that the head of an infant will not enter. The age category to be assumed when implementing the test method and confirmation method is determined based on the age at which infants are believed to start crawling.

[0029] Next, the possibility of an infant entering through the legs is examined based on the test and confirmation methods described in Section 4.3.5.1 a) of Non-Patent Document 5, which assumes entry from the leg direction. If it cannot be determined that entry from the leg direction poses a low risk of head / neck entrapment, the following two measures (i) and (ii) are taken. (i) Prohibit use in places with significant steps, such as stairs, or provide parts to close gaps and require that gaps be closed when using in such places. (ii) If the obstacle of the present invention is in the form of a door, make the door movable in both forward and backward directions so that an infant can be safely removed.

[0030] In this embodiment, the width (height in this embodiment) of the gap P1 through which the self-propelled device passes may be less than 120 mm. It is preferably 80 to 110 mm. The height (thickness) of the rung 132 may be 20 mm or less. The gap width is a passable height calculated based on the size of a typical self-propelled device, Roomba (registered trademark), and is a height that can be confirmed to prevent the head of an infant at the crawling stage from entering using the test and confirmation method described in Non-Patent Document 5, which assumes entry from the head direction. Specifically, the narrowest head probe size for infants aged 6 to 9 months, the age at which most infants begin to crawl, is 120 mm, preventing infant entry. The height of the rung 132 is also known as the height that the aforementioned Roomba (registered trademark) can climb over.

[0031] Furthermore, the size of the gap P1 in the obstacle 100 may be changeable based on the growth of the infant, etc. For example, the structure may be such that the height of the shielding plate 120 can be adjusted up and down when fixed to the support 130. Specifically, the structure may be such that the attachment position of the fixing means 140 to the shielding plate 120 and the attachment position of the fixing means 140 to the support 130 can be changed.

[0032] FIG. 1B shows a first modification of this embodiment. In this modification, the basic configuration is the same as in the first embodiment, but the shielding plate 120 is cut in the middle and separated into shielding plates 120a and 120b. A first side end 126 and a second side end 128 are each connected to a support 130 by connecting means 150, and in this modification, the shielding plates 120a and 120b form a double-hinged door. In this case, too, a stopper (not shown) may be provided to prevent the obstacle 112 from opening or closing accidentally.

[0033] 1C shows a second modification of this embodiment. In this second modification, the basic configuration is the same as that of the first embodiment, but the shielding plate 120 is fixedly attached to the support 130. In other words, the obstacle 114 does not have a door structure, but is used as a barrier surface. Note that although the obstacle 114 is shown as having no bars, it may have bars.

[0034] With this structure, the obstacle 900 will not be accidentally opened, and a structure can be provided that restricts the movement of infants and young children, while allowing automatic equipment to pass through.

[0035] These modifications of the shielding plate 120 may also be combined with other embodiments described below.

[0036] 2 is a perspective view of an obstacle 200 according to a second embodiment of the present invention. The basic configuration of the obstacle 200 is the same as that of the first embodiment, but the second embodiment differs from the first embodiment in that the crosspiece 232 is provided above the shielding plate 120.

[0037] Therefore, in this embodiment, the crosspiece 232 receives the force that the support 230 receives from the fixing means 240, and a gap P1 through which the self-propelled equipment can pass is formed between the lower end 222 of the shielding plate 120 and the floor surface. This structure makes it easier for the self-propelled equipment to pass through the gap P1.

[0038] 3 is a perspective view of an obstacle 300 according to a third embodiment of the present invention. The basic configuration of the obstacle 300 is the same as that of the first embodiment, but the third embodiment differs from the first embodiment in that the fixing means 340 is a means other than a pole-type device.

[0039] The fixing means 340 may be, for example, an adhesive, metal fittings, an external slot, or the like. When the fixing means 340 is an adhesive, any adhesive may be used as long as it provides sufficient strength to fix the obstacle 500. The adhesive may also be in the form of a tape, and may be provided on the entire or part of the support 530. When the fixing means 340 is metal fittings, the obstacle 500 may be fixed to an indoor space such as a wall using multiple metal fittings.

[0040] Such a structure allows the obstacle 300 to be firmly installed.

[0041] 4 is a perspective view of an obstacle 400 according to a fourth embodiment of the present invention. The basic configuration of the obstacle 400 is the same as that of the first embodiment, but the fourth embodiment differs from the first embodiment in that support posts 430 extend from near the floor to near the ceiling, and fixing means 440 are provided at each end of the support posts, and the support posts are fixed in contact with the ceiling and floor, rather than the wall.

[0042] In one embodiment, the obstacle 400 does not have a crosspiece, but is fixed by the fixing means bracing it vertically. The support posts 430 are formed from hollow aluminum alloy material, and the upper part of the support posts 430 on both sides is provided with a mechanism for bracing it against the ceiling surface with bolts and nuts, and the obstacle 400 is fixed by being braced on the upper and lower surfaces. The structure is similar to the mechanism of the fixing means in the first embodiment. The lower part of the shielding plate 420 is located above the bottom of the obstacle 400, and there is a gap P1 for the self-propelled equipment to pass through.

[0043] Since the obstacle 400 is not fixed by being braced on both sides, no crosspieces are required between the opposing supports 430 on both sides, but crosspieces may be provided to stabilize the supports 430.

[0044] In this embodiment, a bracing method was selected as the method for fixing to the top and bottom surfaces, but fixing may also be performed using metal fittings or a strong adhesive.

[0045] With this structure, the obstacle can be stably installed even when there is no wall surface on which to install the fixing means in the lateral direction.

[0046] 5A to 5C are perspective views of obstacles 510, 512, and 514 according to a seventh embodiment of the present invention. The basic configurations of the obstacles 510, 512, and 514 are the same as those of the first embodiment, but the fifth embodiment differs from the first embodiment in that these obstacles have a self-supporting structure.

[0047] 5A is provided with a support plate 534 instead of a crosspiece, and is structured to allow the obstacle 510 to stand upright together with the support post 530. The height of the support plate 534, like the crosspiece 132, is equal to or less than the height that the self-propelled device can climb over.

[0048] The support plate 534 may be formed from the same material as the support pole 530 and the shielding plate 520, or may be formed from a different material. For example, it may be formed from a metal plate, in which case it can be installed stably. Furthermore, by providing the support plate 534 with a sufficient width, an infant can only brace themselves on the support plate 534 when pushing the obstacle 510, preventing the obstacle 510 from moving. In addition, if the support plate 534 is sloped, the joint area between the support plate 534 and the support pole 530 can be increased to provide strength and make it easier for the self-propelled device to overcome the obstacle 510.

[0049] 5B has a self-supporting structure and includes legs 536. The legs 536 form a T-shape with the support posts 530 and the crosspieces 532, respectively, allowing the obstacle 512 to be stably installed.

[0050] 5(c) has legs 536 as a freestanding structure, but does not have crosspieces 532. Therefore, the distance from the floor to the bottom end 722 of the shielding plate 720 is the size of the gap P1, and the structure allows the obstacle 514 to be installed stably while allowing self-propelled equipment to easily pass through.

[0051] These structures make it possible to provide a partition structure that can be installed anywhere without the need for walls, and that prevents infants from passing through while allowing self-propelled equipment to pass through.

[0052] Sixth Embodiment FIG. 6 is a perspective view of an obstacle 600 according to a sixth embodiment of the present invention. The basic configuration of the obstacle 600 is the same as that of the fifth embodiment, but differs from the fifth embodiment in that multiple obstacles are used in combination. As shown in FIG. 6, the obstacles 600 can form an independent playpen by arranging multiple obstacles (610, 612) in a circle and connecting adjacent obstacles. Alternatively, multiple obstacles may simply be connected to each other and used to divide an indoor space. Connecting multiple obstacles increases the overall weight of the obstacle 600, preventing unexpected movement of the obstacle 600.

[0053] The obstacles 600 may also form a wall (obstacle 612) in which the shielding plate 620 is fixedly attached to the support 630, except for one of the connected obstacles. Also, the obstacle 610 in which the shielding plate 620 is movably connected to the support 630 can be used as an entrance and exit for the playpen.

[0054] 7 is a perspective view of an obstacle 700 according to a seventh embodiment of the present invention. The basic configuration of the obstacle 700 is the same as that of the first embodiment, but the seventh embodiment differs from the first embodiment in that gaps P3 and P4 are provided between the support 730 and the wall of the indoor space, allowing a self-propelled device to pass through.

[0055] In this embodiment, examples of the self-propelled device include a window cleaning robot or wall cleaning robot that can move on a wall surface, and a toy.

[0056] The size (width) of the gaps P3 and P4 is determined in the same manner as the gap P1, depending on the dimensions of the self-propelled device to be passed through and the possibility of infants passing through.

[0057] Although the obstacle 700 in FIG. 7 is shown as having no gap P1 between the lower end 722 of the shielding plate 720 and the floor, the obstacle 700 may have gap P1 as well as gaps P3 and P4.

[0058] With this structure, in this embodiment, it is possible to restrict the movement of the baby without restricting the movement of the automatic device that moves along the wall surface.

[0059] 8 is a perspective view of an obstacle 800 according to an eighth embodiment of the present invention. The basic configuration of the obstacle 800 is the same as that of the first embodiment, but the eighth embodiment differs from the first embodiment in that it further includes a lower door 860 that covers at least a portion of the gap P1.

[0060] The lower door 860 is connected to the lower end 822 of the shielding plate 820 and normally closes the gap P1, but when the self-propelled equipment passes through, it is opened by the self-propelled equipment pushing it up or by automatic control, allowing the automatic equipment to pass through the gap P1.

[0061] The lower door 860 may be made of a material such as cloth, wood, resin, metal, or a combination thereof. In the case where the self-propelled device has a push-up structure, the lower door 860 is preferably lightweight.

[0062] The lower door 860 allows the user to select between a state where a self-propelled device can pass through while still preventing infants and young children from passing through, and a state where a self-propelled device cannot pass through. For example, if an obstacle based on the present invention is installed at the entrance to a bedroom, the user may want a household robot vacuum cleaner to clean the room when the user is away, but can prevent the robot from entering when the user is sleeping. The open / close state of the lower door 860 may be controlled by a latch or the like.

[0063] Although various embodiments and modifications have been described above, the present invention is not limited to these. Other embodiments that are conceivable within the scope of the technical idea of ​​the present invention are also included within the scope of the present invention.

[0064] For example, an obstacle to be installed in an indoor space of the present invention includes a shielding plate and a pair of support posts that sandwich the shielding plate and have the shielding plate connected to at least one of the support posts, the support posts extending parallel to the direction of gravity, and a gap that allows a self-propelled device smaller than a baby to pass through between an end of the shielding plate and the indoor space, and includes the following embodiments.
