JP 2019-163609 A

However, in the baby gate of Patent Document 1, the height of the lower frame of the frame body is 3 cm or more. There is a danger of stepping on the lower frame and twisting the ankle, resulting in a sprain. This is the same for adults, including the elderly and physically handicapped, and pets, including old and sick dogs (hereinafter sometimes referred to as "children, etc.").
Also, in recent years, a cleaning robot that automatically cleans the floor of a room has been developed and attracts attention.
However, this cleaning robot cannot pass through the lower frame of the baby gate, which is 3 cm or more in height, and cannot clean a wide area across the gate.

Therefore, as a result of intensive research, the inventor has found that even if children, etc. touch the bottom frame with their toes or step on the bottom frame from above when passing through the gate, they can safely walk and the cleaning robot can pass. We found that all the above-mentioned problems could be solved by lowering the lower frame to the possible height, and completed this idea.

The present invention has been devised in view of such problems. When a child or the like passes through a gate, even if the foot touches the lower frame, the child can walk safely and the cleaning robot can be used. To provide a barrier-free gate that allows a person to pass through the gate without any trouble.

The device according to claim 1 comprises a frame fixed to an indoor passage and having a hanger-side vertical frame, a door-end-side vertical frame and a lower frame, and a door pivotally supported by the hanger-side vertical frame. , wherein the lower frame has a height of 1 cm to 2 cm.

The term "indoor passage" as used herein means, for example, passages such as corridors, stairs, and entrances.
The type (application) of the barrier-free gate is not limited. For example, gates for baby gates and playpens that restrict the passage of children, pet gates that restrict the passage of pets such as dogs and cats, gates for pet circles, and the like.
Any material can be used for the frame. For example, various metals (iron, steel (steel), aluminum alloy, etc.), various plastics (ABS resin, polycarbonate, polyvinyl chloride resin, etc.), various woods (pine, cedar, pine, cypress, etc.) can be adopted.

The term "door" as used herein refers to a hinged door that is hinged to the vertical frame on the hanger side. It may be of a type that opens only in one direction, forward or backward, or a type that opens in both directions.
The material of the door is arbitrary. For example, various metals, various plastics, various woods, etc. can be used.
Moreover, the door may be of a fence shape or a panel shape as long as it can block the passage.
The type of door is arbitrary. For example, an auto-close type is adopted in which the door is always rotated to the closed position, provided with a closing spring that always urges the door toward the closed position and a lock means that locks the door at the closed position. You may Of course, a general door that does not adopt this method may be used.

If the height of the lower frame is less than 1 cm, there is a risk that the strength of the frame body as a lower component may be insufficient. On the other hand, if the height exceeds 2 cm, the lower frame is too high, and there is a risk that children, etc., may easily stumble by hitting their toes against the side of the lower frame, or they may easily twist their ankles when stepping on the lower frame. Moreover, there is a risk that the cleaning robot will not be able to pass through the gate.

The term "children" as used herein refers not only to children, but also to adults including the elderly and physically handicapped, and pets including old and sick dogs.
A preferred height of the lower frame is around 1.5 cm. Within this range, sufficient strength can be obtained as a lower component of the frame, and when a child or the like passes through a gate, even if their toes touch the lower frame, they will not stumble and will not step on the lower frame. But it's hard to twist your ankle. Furthermore, if the height of the lower frame is 1.5 cm, the cleaning robot can smoothly pass through the gate.

According to a second aspect of the present invention, there is provided the barrier-free gate according to the first aspect, wherein the width of the lower frame is 2 cm to 5 cm.

If the width of the lower frame is less than 2 cm, the width of the lower frame is too narrow, and there is a possibility that the strength of the frame body as a lower component may be insufficient. On the other hand, if the width exceeds 5 cm, the width of the lower frame is too wide, and the possibility that a child's foot contacts the lower frame when passing through the gate increases. A preferable width of the lower frame is around 3.5 cm. Within this range, it is possible to obtain sufficient strength as a lower component of the frame body, and to reduce the possibility that a child's foot will contact the lower frame as much as possible when passing through the gate.

A device according to claim 3 is the barrier-free gate according to claim 1 or claim 2, wherein both ends of the lower frame in the width direction are chamfered to have a semicircular cross section.
Chamfering into a semicircular cross-section here refers to "Bose chamfering" in which the thickness at both ends of the lower frame in the width direction is rounded from the center, and the cut surface when viewed from the side is processed into a semi-cylindrical shape. is.

According to the idea of claim 1, the height of the lower frame of the frame (the step with the floor surface) is as low as 1 cm to 2 cm, so when children pass through the barrier-free gate, if the child etc. Even if it abuts against the side surface of the frame, it is difficult to stumble, and even if a child steps on the lower frame from above, an injury such as twisting the ankle can be prevented. Moreover, the cleaning robot can pass through the gate without any trouble and clean a wide range of floors.

In particular, according to the second aspect of the invention, since the lower frame of the frame body has a height of 1 cm to 2 cm and a width of 2 cm to 5 cm, the strength of the lower structure of the frame body is increased. In addition, it is possible to reduce the possibility that the foot of a child or the like comes into contact with the lower frame when passing through the gate.

In addition, according to the device of claim 3, since both ends of the lower frame in the width direction are chamfered into a semicircular cross section, children, etc., when passing through the gate, are less likely to be disturbed than when the lower frame is made of rectangular timbers with a square cross section. It is possible to enhance the safety when the foot is applied to the lower frame.

This barrier-free gate 10 is fixed to an upper passageway (indoor passageway) 11 having a length of stairs, and has an upward U-shape having a suspension-side vertical frame 12, a door-side vertical frame 13, and a lower frame 14. and a fence-like door 18 pivotally supported on the hanger-side vertical frame 12 so as to be openable forward and rearward via an upper pivot portion 16 and a lower pivot portion 17 .

The barrier-free gate 10 has an auto-close function in which the door 18 in the open state is automatically rotated and closed. This auto-close mechanism includes a closing spring (not shown) provided in the lower shaft support portion 17 to always bias the door 18 toward the closed position, and an upper lock portion 19 for unlockably locking the door 18 at the closed position. and a lower lock portion 20, and also has a structure in which the door 18 is locked in a fully open state if the door opening angle is 90°. Since such an auto-lock mechanism is not directly related to the gist of the present invention, a detailed description with drawings will be omitted here.

The door 18 is a steel fence in the form of a vertical lattice in which eight vertical door frames 23 are stretched between an upper door frame 21 and a lower door frame 22 at a predetermined pitch.
Further, the suspension-side vertical frame 12 on the X2 side, the door-end-side vertical frame 13 on the X1 side, and the lower frame 14 on the Z1 side, which constitute the frame body 15, are members made of steel.
Of these, the lower frame 14 has a height a of 1.5 cm, which is about half the height of the conventional product, and a width b of 3.5 cm. In addition, both ends of the lower frame 14 in the width direction are chamfered to have a semicircular cross section to prevent stumbling when a child's toe hits it (see FIGS. 2 and 3). The term "children" as used herein refers not only to children, but also to adults including the elderly and physically handicapped, and pets including old and sick dogs.

A total of four bolt and nut type adjusters 24 are arranged on the outside of the four corners of the frame 15 for fixing the frame 15 in parallel to the left and right wall surfaces of the upper passage 11 of the stairs in a tensioned state. is set. If the gap between the left and right wall surfaces of the upper passage 11 and the frame body 15 is large, a pair of additional left and right extended vertical frames (not shown) may be connected.

An upper support body 25 is fixed to the upper end of the suspension-side vertical frame 12. The upper support body 25 is substantially the half on the X2 side of the upper support 16 having a long streamline shape in the X1-X2 direction. On the other hand, at the edge of the door top frame 21 on the side of the door trailing edge, there is a half of the upper shaft support portion 16 on the X1 side, which is the tip portion of the upper shaft support main body 25 recessed in a stepped manner and extends in the Z1-Z2 direction. A slidably connected upper pivotal pivot 26 is fixed. A pull-back spring (not shown) is incorporated in the tip of the upper shaft support portion 16 to always force the upper shaft support rotor 26 downward against the upward sliding motion thereof.

Furthermore, a lower pivotal support body 27, which is a main part of the lower pivotal support part 17 and has a stepped recess at the tip, is fixed to the lower end of the suspension-side vertical frame 12. As shown in FIG. On the other hand, at the end of the door lower frame 22 on the side of the door trailing edge, a narrow and short door is pivotally supported by the leading end of the lower pivotal support portion 17 so as to be slidable in the Z1-Z2 direction, and the door closing spring is built therein. A rectangular lower pivotal support rotating body 28 is fixed. Even if the door 18 is rotated in either direction, the door 18 is returned to the original closed position by the spring force of the door closing spring.

Next, the upper locking portion 19 will be described.
An upper lock body 29, which is substantially the X1 side half of the large streamlined upper lock portion 19 elongated in the X1-X2 direction, is fixed to the upper end portion of the door leading edge side vertical frame 13. As shown in FIG. A lock recess (not shown) is formed in the center of the end face of the upper lock body 29 on the side of the door trailing edge. On the other hand, an upper lock operation body 30, which is a half of the upper lock portion 19 on the X2 side, is fixed to the end portion of the door upper frame 21 on the door tip side.

An upper lock pin (not shown) biased outward by a spring is provided on the end face of the upper lock operation body 30 on the side of the door so as to be able to project and retract. Further, on the top surface of the upper lock operation body 30 on the side of the door, the upper lock pin is pulled into the upper lock operation body 30 against the spring force, thereby releasing the locked state of the upper lock pin from the lock recess. A lock release lever 31 is attached so as to be slidable in the X1-X2 direction.

When the door is closed by the auto-close mechanism, the door 18 reaches the closed position due to the spring force of the closing door spring, and the upper lock pin of the upper lock operation body 30 is engaged with the lock concave portion of the upper lock body, thereby closing the door 18. The upper part is locked by the upper locking part 19 .
On the other hand, when unlocking the upper lock portion 19, the upper lock pin is pulled out from the lock concave portion by pulling the lock release lever 31 in the X2 direction against the spring force.

Next, the lower lock portion 20 will be explained.
A lower lock body 32 is fixed to the lower end portion of the door tip side vertical frame 13, the end portion of which is tapered on the door bottom side in a stepped manner. In the end face of the upper part of the lower lock body 32 on the side of the door trailing edge, a locking groove having an open upper surface and having a mountain shape in plan view is formed (not shown).
On the other hand, a narrow and short rectangular lower lock operation body 33, which is substantially half of the lower lock portion 20 on the X2 side, is fixed to the end portion of the door lower frame 22 on the door tip side. A lower lock pin biased outward by a spring is protrusively and retractably provided on the end face of the lower lock operation body 33 on the side of the door (not shown).

Next, how to use the barrier-free gate 10 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG.
As shown in FIG. 1, when passing through the barrier-free gate 10, the door 18 is first opened.
Specifically, an adult grips the upper lock operation body 30 of the upper lock portion 19 and slides the lock release lever 31 in the X2 direction against the spring force. As a result, the upper lock pin is pulled out from the lock recess, and the locked state of the upper lock portion 19 is released.

Next, if this state is maintained and the upper lock operation body 30 is lifted, the door 18 slides slightly upward, and the locked state of the lower lock portion 20 is also released. Specifically, when the upper locking operation body 30 is lifted, the upper pivotal support rotating body 26 of the upper pivotal support portion 16 slides slightly upward. On the other hand, in the lower shaft support portion 17, the lower shaft support rotating body 28 slides slightly upward against the spring force in the extension direction of the door closing spring. As a result, the entire door 18 is slightly lifted, the lower locking pin is extracted from the released upper surface of the locking groove, and the locked state of the lower locking portion 20 is released.

After that, when the door 18 is rotated forward (Y1 direction) or backward (Y2 direction) by 90° around the upper and lower shaft support portions 16 and 17 against the spring force of the door closing spring, The door 18 is locked in the fully open state by the fully open lock structure.

This allows children and the like to freely pass through the barrier-free gate 10 .
At that time, as shown in FIGS. 2 and 3, the height a of the lower frame 14 in contact with the floor surface (the difference in level with the floor surface) is as low as 1.5 cm, so if the toes of a child or the like are placed on the front side of the lower frame 14 It is hard to stumble even if it hits the rear side. Moreover, since the height a of the lower frame 14 is thus low, even if a child or the like steps on the lower frame 14 when passing through the gate, it is possible to prevent injury such as twisting the ankle. Furthermore, a cleaning robot that automatically cleans the floor of a room can smoothly pass through the lower frame 14 and clean a wide area of the room.

In particular, since the width of the lower frame 14 is shortened to 3.5 cm here, good strength can be obtained as the lower structural body of the steel frame, and a child's foot hits the lower frame 14 when passing through the gate. It is possible to reduce the possibility of contact.
Moreover, both ends of the lower frame 14 in the width direction are Bose chamfered to have a semicircular cross section. Therefore, compared with the case where the lower frame 14 is a conventional square timber with a square cross section, the safety when a child or the like hits the lower frame 14 when passing through the gate is enhanced.

This idea is a barrier-free gate technology that can prevent trips that occur not only for children, but also for adults including the elderly and physically disabled, and pets including old and sick dogs when they pass through the gate. Useful.
