Description

Technical Field

[0001] The present invention relates to an obstacle that can be placed in an indoor space. Specifically, the present invention relates to an obstacle that forms a clearance space between itself and an indoor space such that self-propelled devices can pass therethrough while infants / toddlers cannot pass therethrough.Background Art

[0002] Since infants / toddlers lack discernment, it is necessary to keep them away from dangerous rooms and areas such as kitchens and bathrooms. For this purpose, there have been products serving as obstacles in the forms of barriers and doors that are used by being placed, and they are known as baby gates, baby fences, safety gates, safety fences, playpens, and the like as described in Patent Literature 1, Patent Literature 2, Non Patent Literature 1, and Non Patent Literature 2 listed below and the like.

[0003] For example, a product called a baby gate, in particular, among products in the related art is a door that is fixed by expanding to fit to side surfaces. A structure at the center includes two pillars that are hollow materials made of an aluminum alloy and face the side surfaces, and a crosspiece therebetween. These pillars and the crosspiece are firmly coupled by welding.

[0004] A mechanism for expanding to fit to each side surface with a bolt and nuts is provided at each pillar on the side facing the side surface. In the mechanism, an unthreaded hole is opened horizontally to the floor and a bolt made to pass through two nuts is inserted into the hole. The nut on the wall side is for increasing a contact surface to prevent the wall from being damaged, and the nut on the pillar side has a mechanism in which the interval between the two nuts is increased by the nut on the pillar side being fastened to thereby expand to fit to both sides. The structure at the center is fixed to a doorway, a pathway, or the like by supporting the expanding and fitting force by the crosspiece grounded on the floor surface.

[0005] Additionally, doors configured by attaching plates to wooden frames are fixed to the structure at the center to prevent passage. One of the doors is fixed to a pillar with two double-swing hinges. On the side of the other pillar, a hasp that is provided at the door itself and can be opened and closed is provided. This is a small latch incorporated inside the door and is adapted such that an openable / closable state is changed by causing the latch to project by an upper slide mechanism and inserting the latch into a hole on the pillar side.

[0006] On the other hand, self-propelled devices such as robot cleaners have become widespread in recent years and are known as products names such as a Roomba (registered trademark) and a RULO (registered trademark) as described in Non Patent Literature 3, Non Patent Literature 4, and the like.Citation ListPatent Literature

[0014] Although embodiments of the present invention will be described below in detail, the present invention is not limited thereto.(First Embodiment)

[0015] Figure 1(a) is a perspective view of an obstacle 100 according to a first embodiment of the present invention (hereinafter, simply referred to as an "obstacle"). The obstacle 100 includes a shielding plate 120 and a pair of support pillars 130 sandwiching the shielding plate 120. The support pillars 130 extend parallel to the direction of gravity, and the obstacle 100 is fixed to an indoor space (not illustrated) with fixing unit 140 provided at the support pillars 130.

[0016] In the present embodiment, a clearance space P1 is provided between a lower end 122 of the shielding plate 120 and a floor such that self-propelled devices can pass therethrough. Also, a crosspiece 132 is provided between end portions of the support pillars 130 that are in contact with the floor such that the crosspiece 132 contributes to fixation of the obstacle 100. Hereinafter, details of each component will be described.

[0017] The shielding plate 120 is a plate to suppress movement of infants / toddlers.

[0018] The shielding plate 120 can be formed of wood, resin, metal such as aluminum or an aluminum alloy, or the like. An entirety or a part of the shielding plate 120 may be solid or a hollow structure as long as sufficient strength is achieved. Even in a case where a member with low strength is used, sufficient strength may be obtained by introducing a structure for reinforcement such as a brace. Furthermore, a cushion material may be provided on the surface of the shielding plate 120 to enhance safety.

[0019] It is only necessary for the shielding plate 120 to suppress passage of infants / toddlers, and the shielding plate 120 may have a palisade shape or a net shape as well as a plate shape. In this case, the clearance space of the palisade or the net have a size that does not allow infants / toddlers to pass therethrough.

[0020] The support pillars 130 are members that sandwich the shielding plate 120 and extend parallel to the direction of gravity. The shielding plate 120 is coupled to the support pillars 130 with coupling unit 150. In the present embodiment, the coupling unit 150 may be movable members such as hinges, for example. It is thus possible to use the obstacle 100 as a single-swing door. Also, a stopper (not illustrated) may be provided to prevent the obstacle 100 from being unintentionally opened or closed. It is possible to change an openable / closable state by incorporating a small latch inside the door, causing the latch to project by an upper slide mechanism, and inserting the latch into a hole on the pillar side.

[0021] The support pillars 130 can be formed of a material similar to that of the shielding plate 120. For example, it is possible to form the support pillars 130 with a light weight while maintaining strength by forming them from hollow materials (pipes) made of an aluminum alloy.

[0022] In the present embodiment, the crosspiece 132 is provided between the end portions of the support pillars 130 that are in contact with the floor. The crosspiece 132 is adapted to maintain the distance between the support pillars 130 at a specific distance while receiving a force applied from the fixing unit 140, which will be described later, to the support pillars 130. The support pillars 130 and the crosspiece 132 are firmly coupled through welding, for example. Furthermore, the crosspiece 132 increases the contact area between the obstacle 100 and the floor and contributes to placement stability of the obstacle 100. On the other hand, since self-propelled devices pass over the crosspiece 132 as will be described later, the thickness (height) of the crosspiece 132 has to be a thickness that allows the self-propelled devices to cross over the crosspiece 132.

[0023] The support pillars 130 are fixed to an indoor space by the fixing unit 140. The indoor space for the fixation may be, for example, walls of a pathway or an entrance.

[0024] The fixing unit 140 may be any fixing unit as long as it is possible to fix the support pillars 130 sandwiching the shielding plate 120 to the indoor space. For example, the fixing unit 140 may be a mechanism (pole-type equipment) for expanding to fit to side surfaces with a bolt and nuts and may be provided to face the wall for placement from each support pillar 130. This mechanism is obtained by opening an unthreaded hole horizontally to the floor and inserting a bolt inserted into two nuts into the hole. The nut on the wall side is for increasing the contact surface to prevent the wall from being damaged, and the nut on the pillar side has a mechanism in which the interval between the two nuts is increased by the nut on the pillar side being fastened to thereby expand to fit to both sides. The support pillars 130 are fixed to a doorway, a pathway, or the like by supporting the expanding and fitting force by the crosspiece 132 grounded on the floor surface.

[0025] In the present embodiment, a clearance space P1 that is smaller than infants / toddlers and allows self-propelled devices to pass therethrough is provided between the lower end 122 of the shielding plate 120 and the floor. Note that although the drawing illustrates passage of a self-propelled device by an arrow, the self-propelled device does not move only in the direction and can pass through the clearance space P1 in any direction.

[0026] The height of the clearance space P1 is determined in accordance with the dimension of the self-propelled device to be allowed to pass therethrough and a possibility of passage of infants / toddlers. The dimension of the self-propelled device to be allowed to pass therethrough is acquired from information from its manufacturer or by actual measurement of the actual device.

[0027] On the other hand, the possibility of passage of infants / toddlers is defined based on standards of public institutions, industry organizations, and the like of each country, actually measured values, and the like. For products for domestic use in Japan, for example, it is basically possible to define the width of the clearance space based on each test method in Non Patent Literature 5. For products for use in Europe and the like, it is possible to define the width of the clearance space based on each test method in Non Patent Literature 6.

[0028] A method of defining the width of the clearance space based on the method described in Non Patent Literature 5 will be described as an embodiment. First, it is confirmed that head parts of infants / toddlers do not enter the clearance space based on the test method and the confirmation method assuming entrance from the head part direction as described in Section 4.3.5.1 b) in Non Patent Literature 5. An age classification to be assumed at the time of carrying out the test method and the confirmation method is determined based on ages of infants / toddlers who are considered to crawl.

[0029] Next, a possibility that infants / toddlers enter the clearance space from their leg parts is considered based on the test method and the confirmation method assuming entrance from the leg part direction as described in Section 4.3.5.1 a) of Non Patent Literature 5. At this time, the following two countermeasures (i) and (ii) are taken in a case where it is not possible to determine that the possibility of a hazard of head parts / neck parts getting stuck in the case of entrance from the leg part direction is low. (i) To prohibit utilization at a location with a significant step difference such as stairs, or to provide a part to block the clearance space and require use of the obstacle by blocking the clearance space when the obstacle is used at such a location. (ii) To enable the door to move in both directions such that infants / toddlers are allowed to safely move away in a case where the obstacle according to the present invention is in the form of a door.

[0030] In the present embodiment, the width (the height in this embodiment) of the clearance space P1 for the self-propelled device to pass may be less than 120 mm. The width is preferably 80 mm to 110 mm. Also, it is only necessary for the height (thickness) of the crosspiece 132 to be equal to or less than 20 mm. The width of the clearance space is a height that is calculated from the size of a Roomba (registered trademark), which is a representative self-propelled device, such that the Roomba can pass therethrough, and is also a height at which it is possible to confirm that head parts of infants / toddlers in a crawling period do not enter the clearance space by the test method and the confirmation method assuming entrance from the head part direction as described in Non Patent Literature 5. Specifically, narrower widths of sizes of head probes of infants of 6 months old or more to less than 9 months old, many of whom start crawling, are 120 mm, and it is possible to prevent entrance of infants therewith. Also, the height of the crosspiece 132 is known as a height that allows the above-described Roomba (registered trademark) can cross over the crosspiece 132.

[0031] In the obstacle 100, the size of the clearance space P1 can be changed based on growth of infants / toddlers and the like. For example, a structure capable of vertically adjusting the height of the shielding plate 120 when the shielding plate 120 is fixed to the support pillars 130 may be adopted. Specifically, a structure capable of changing the positions of attachment of the fixing unit 140 to the shielding plate 120 or the positions of attachment of the fixing unit 140 to the support pillars 130 may be included.

[0032] Figure 1(b) illustrates a first modification of the present embodiment. Although a basic configuration in the first modification is the same as that in the first embodiment, the shielding plate 120 is cut at the center and is split into shielding plates 120a and 120b. Also, the first modification has a structure in which each of a first side end 126 and a second side end 128 is coupled to each support pillar 130 with a coupling unit 150, and the shielding plates 120a and 120b form a double-swing door in the first modification. Stoppers (not illustrated) may be provided to prevent an obstacle 112 from being unintentionally opened or closed in this case as well.

[0033] Figure 1(c) illustrates a second modification of the present embodiment. Although a basic configuration in the second modification is the same as that in the first embodiment, the shielding plate 120 is immovably fixed to the support pillars 130. In other words, an obstacle 114 does not have a door structure and is used as a barrier surface. Note that although the structure of the obstacle 114 that does not include a crosspiece is illustrated, the obstacle 114 may include a crosspiece.

[0034] With such a structure, the obstacle 114can provide a structure that is not intentionally opened, suppresses movement of infants / toddlers, and allows self-propelled devices to pass therethrough.

[0035] Also, these modifications related to the shielding plate 120 may be combined with other embodiments described below.(Second Embodiment)

[0036] Figure 2 is a perspective view of an obstacle 200 according to a second embodiment of the present invention. Although a basic configuration of the obstacle 200 is the same as that in the first embodiment, the second embodiment is different from the first embodiment in that a crosspiece 232 is provided on a side further upward than a shielding plate 120.

[0037] Therefore, in the present embodiment, a clearance space P1 that allows self-propelled devices to pass therethrough is formed between a lower end 222 of the shielding plate 120 and a floor surface with a crosspiece 232 accepting a force that support pillars 230 receive from fixing unit 240. Such a structure makes it easier for the self-propelled devices to pass through the clearance space P1.(Third Embodiment)

[0038] Figure 3 is a perspective view of an obstacle 300 according to a third embodiment of the present invention. Although a basic configuration of the obstacle 300 is the same as that in the first embodiment, the third embodiment is different from the first embodiment in that fixing unit 340 is unit other than pole-type equipment.

[0039] As the fixing unit 340, it is possible to use, for example, an adhesive, a metal fitting, an external slot, or the like. In a case where the fixing unit 340 is an adhesive, it is possible to use any adhesive as long as it provides sufficient strength to fix the obstacle 300. Also, the adhesive may have a tape shape and may be provided entirely or partially on support pillars 330.

[0040] In a case where the fixing unit 340 is a metal fitting, the obstacle 300 may be fixed to an indoor space such as walls with a plurality of metal fittings.

[0041] With such a structure, it is possible to firmly place the obstacle 300.(Fourth Embodiment)

[0042] Figure 4 is a perspective view of an obstacle 400 according to a fourth embodiment of the present invention. Although a basic configuration of the obstacle 400 is the same as that in the first embodiment, the fourth embodiment is different from the first embodiment in that support pillars 430 extend from a location near a floor to a location near a ceiling and a fixing unit 440 is provided at each end portion thereof to achieve fixation through contact with the ceiling, instead of walls, and the floor in the fourth embodiment.

[0043] In an embodiment, the obstacle 400 does not include a crosspiece and is fixed by fixing unit vertically expanding and being fitted. The support pillars 430 are formed of hollow materials made of an aluminum alloy, upper portions of the support pillars 430 at both side surfaces are provided with mechanisms for expanding and being fitted to the ceiling surface with bolts and nuts, and the obstacle 400 is fixed by the support pillars 430 expanding and being fitted to the upper and lower surfaces. The structure is similar to that of the mechanism of the fixing unit in the first embodiment. A lower portion of a shielding plate 420 is provided on the side further upward than the bottom portion of the obstacle 400, and there is a clearance space P1 for self-propelled devices to pass therethrough.

[0044] Since the obstacle 400 does not adopt a scheme in which the obstacle 400 is fixed by expanding and being fitted to both side surfaces, a crosspiece is not needed between the opposite support pillars 430 at both side surfaces. However, a crosspiece may be provided to stabilize the support pillars 430.

[0045] Although a method of expanding and being fitted is chosen as a method of achieving fixation to the upper and lower surfaces in the present embodiment, fixation may be achieved by metal fittings, a strong adhesive, or the like.

[0046] With such a structure, it is possible to stably place the obstacle even in a case where there are no wall surfaces on which the fixing unit are placed in the lateral direction.(Fifth Embodiment)

[0047] Figures 5(a) to 5(c) are perspective views of obstacles 510, 512, and 514 according to a fifth embodiment of the present invention, respectively. Although basic configurations of the obstacles 510, 512, and 514 are the same as that in the first embodiment, the fifth embodiment is different from the first embodiment in that these obstacles have self-standing structures.

[0048] The obstacle 510 illustrated in Figure 5(a) is provided with a support plate 534 instead of a crosspiece and has a structure to achieve self-standing of the obstacle 510 along with support pillars 530. The height of the support plate 534 is equal to or less than the height that allows self-propelled devices to cross over the support plate 534 similarly to the crosspiece 132.

[0049] The support plate 534 may be formed of a material that is similar to those of the support pillars 530 and a shielding plate 520 or may be formed of a different material. For example, the support plate 534 can be formed of a metal plate, and in that case, it is possible to achieve stable placement. Furthermore, infants / toddlers can hang on only on the support plate 534 when pushing the obstacle 510 by providing a sufficiently wide support plate 534, and it is possible to prevent them from moving the obstacle 510. Additionally, in a case where the support plate 534 is formed into a slope shape, strength is provided by increasing the area of the portions where the support plate 534 and the support pillars 530 are joined to each other, and it becomes easier for self-propelled devices to cross over the obstacle 510.

[0050] The obstacle 512 illustrated in Figure 5(b) includes leg portions 536 as a self-standing structure. The leg portions 536 form T-shaped structures with each of the support pillars 530 and the crosspiece 532 and enable the obstacle 512 to be stably placed.

[0051] The obstacle 516 illustrated in Figure 5(c) has a structure in which the obstacle 516 includes the leg portions 536 as a self-standing structure while the obstacle 516 does not include the crosspiece 532. Therefore, the distance from the floor to a lower end 522 of a shielding plate 520 is the size of a clearance space P1, and a structure that allows self-propelled devices to easily pass therethrough while realizing stable placement of the obstacle 514 is achieved.

[0052] With these structures, it is possible to provide partitioning structures that can be placed at any location without requiring walls and the like, suppress passage of infants / toddlers, and allow self-propelled devices to pass therethrough.(Sixth Embodiment)

[0053] Figure 6 is a perspective view of an obstacle 600 according to a sixth embodiment of the present invention. Although a basic configuration of the obstacle 600 is the same as that in the fifth embodiment, the sixth embodiment is different from the fifth embodiment in that a plurality of obstacles 600 are used in combination.

[0054] The obstacle 600 can form an independent playpen by a plurality of obstacles (610, 612) being disposed in a circular shape and coupled to the next obstacles as illustrated in Figure 6. Also, a plurality of obstacles may be simply coupled and used for the purpose of partitioning an indoor space. The weight of the entire obstacle 600 is increased by the plurality of obstacles being coupled, and it is thus possible to prevent the obstacle 600 from being unexpectedly moved.

[0055] All the obstacles except for one among the coupled obstacles in the obstacle 600 may form walls (obstacles 612) by shielding plates 620 being immovably fixed to support pillars 630. Also, the obstacle 610 with the shielding plate 620 movably coupled to the support pillars 630 can be used as an entrance / exit of the playpen.(Seventh Embodiment)

[0056] Figure 7 is a perspective view of an obstacle 700 according to a seventh embodiment of the present invention. Although a basic configuration of the obstacle 700 is the same as that in the first embodiment, the seventh embodiment is different from the first embodiment in that clearance spaces P3 and P4 are provided between support pillars 730 and walls of an indoor space and self-propelled devices can pass therethrough.

[0057] In the present embodiment, the self-propelled devices include a window wiping robot, a wall surface cleaning robot, and a toy that can move along wall surfaces.

[0058] The sizes (widths) of the clearance spaces P3 and P4 are determined in accordance with the dimension of a self-propelled device to be allowed to pass therethrough and a possibility of passage of infants / toddlers similarly to the clearance space P1.

[0059] Note that the obstacle 700 in Figure 7 is disclosed to have a configuration in which no clearance space P1 is included between a lower end 722 of a shielding plate 720 and a floor, the clearance space P1 may be included along with the clearance spaces P3 and P4.

[0060] With such a structure, it is possible to suppress movement of infants / toddlers without suppressing movement of self-propelled devices that move along wall surfaces in the present embodiment.(Eighth Embodiment)

[0061] Figure 8 is a perspective view of an obstacle 800 according to an eighth embodiment of the present invention. Although a basic configuration of the obstacle 800 is the same as that in the first embodiment, the eighth embodiment is different from the first embodiment in that a lower door 860 that covers at least a part of a clearance space P1 is further included.

[0062] The lower door 860 is coupled to a lower end 822 of a shielding plate 820 and usually closes the clearance space P1, and when self-propelled devices pass therethrough, the self-propelled devices can pass through the clearance space P1 by the self-propelled devices pushing up the lower door 860 or by the lower door 860 being automatically controlled and opened.

[0063] The lower door 860 may be formed of a material such as cloth, wood, resin, metal, or a combination thereof. In a case of the structure in which the self-propelled devices push up the lower door 860, the lower door 860 preferably has a light weight.

[0064] The lower door 860 enables a state where the self-propelled devices can pass therethrough and a state where the self-propelled devices are not allowed to pass therethrough to be selected with a state where infants / toddlers are not allowed to pass therethrough maintained. In a case where the obstacle based on the present invention is placed at an entrance of a bedroom, for example, it is desirable to cause a domestic robot cleaner to clean the room when nobody is present while it is possible to prevent the domestic robot cleaner from entering the room at the time of sleeping. The openable / closable state of the lower door 860 may be controlled by a latch or the like.

[0065] Although various embodiments and modifications have been described above, the present invention is not limited to these contents. Other aspects that are conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention.
