Description

  The present invention relates to a baby gate, and more particularly to a baby gate in consideration of child safety.

  A conventional baby gate is described in, for example, Japanese Patent Application Laid-Open No. 2004-150053 (Patent Document 1). The baby gate described in the publication is for preventing children and pets (hereinafter referred to as “children”) from entering and exiting from a specific doorway, and is a frame that is fixed to an indoor wall or the like. And one gate panel rotatably supported by the frame body, and elastic means that acts to always rotate and return the gate panel to the closed state.

The baby gate can create an open state in which a child or the like can pass and a closed state in which the child cannot pass by rotating the gate panel with respect to the frame. In addition, since the gate panel is always returned to the closed state by the elastic means, it is possible to prevent a child or the like from entering a place that should not be entered due to forgetting to tighten.
JP 2004-150053 A

  In the baby gate configured as described above, since one gate panel rotates with respect to the frame, the radius of rotation of the gate panel increases. As a result, a large space is required to install this baby gate.

  In addition, the rotational force of the gate panel increases in proportion to the increase in the radius of rotation. Then, when the gate panel is closed by the elastic means while the child or the like is passing, the risk of the child or the like being injured by being sandwiched between the gate panel and the frame increases.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a baby gate that can be used even in a narrow space and that further improves the safety of children and the like.

  The baby gate according to the present invention includes a pair of support pillars extending in the vertical direction, one side and a side opposite to the one side, a first door member rotatably held on one side of the support pillar, one side and A second door member having opposite sides facing one side, and one side rotatably held by the other column. And the 1st and 2nd door member opposes the opposite sides, and comprises a closed state, and comprises an open state by rotating centering on one side, respectively.

  In the two-door baby gate as described above, the rotation radius of each door member is smaller than that of the one-door door. Further, the rotational force of each door member also decreases in proportion to the decrease in the radius of rotation. As a result, it is possible to obtain a baby gate that can be used in a narrow space and further improves the safety of children and the like.

  Preferably, the baby gate further includes a rotation interlocking mechanism that rotates the second door member in the opposite direction to the first door member in conjunction with the rotation of the first door member. As a result, if one door is rotated, the other door opens in conjunction with the door, making it easier to open the baby gate.

  As one embodiment, the rotation interlocking mechanism is connected to the first door member at one side region where one side end portion is divided by a straight line connecting the rotation centers of the first and second door members, and the other side. It has a link member connected to the 2nd door member in the other side field where a side edge was divided by a straight line. The link member reciprocates between the pair of pillars as the first door member rotates, and rotates the second door member around the opposite direction to the first door member.

  Preferably, each of the first and second door members has an automatic closing mechanism that attempts to return from the open state to the closed state. Thereby, it is possible to prevent a child or the like from entering a place that should not be entered due to forgetting to tighten the door member.

  As one embodiment, the automatic closing mechanism includes a convex portion that protrudes in a vertical direction from one side of the connecting portion between the door member and the support column, and a tip that is inclined at a predetermined angle with respect to the protruding direction, and a bottom surface on the other side. The wall is an inclined surface corresponding to the tip of the convex portion, and includes a concave portion that receives the convex portion, and an elastic member that biases the convex portion and the concave portion in a close contact direction. And in a closed state, it arrange | positions so that the top part of a convex part and the innermost part of a recessed part may correspond. In the open state, the top of the convex portion is located on the inclined surface of the concave portion and attempts to return to the closed state by the restoring force of the elastic member.

  As yet another embodiment, the bottom wall of the recess is formed with a flat surface that extends in a horizontal direction at a position that abuts the top of the projection when the first door member is rotated by a predetermined angle. Yes. Thereby, if a door member is rotated more than a certain amount, it will not return to a closed state automatically, but can remain in an open state.

  More preferably, the second door member includes an automatic closing mechanism. The return speeds of the first door member and the second door member are different from each other. Thereby, it can prevent effectively that a child etc. are pinched between the 1st and 2nd door members. As specific means for varying the return speed, it is conceivable to vary the weights of the first and second door members, vary the elastic force of the elastic member, and the like.

  Preferably, the baby gate further includes a lock mechanism that fixes the first and second door members in a closed state. Thereby, since there is no possibility that a child etc. will open a door member unexpectedly, the safety | security of a baby gate further improves.

  In one embodiment, the baby gate further includes a base member that couples the pair of struts to each other. The locking mechanism includes a first protrusion that protrudes from the opposite side of the first door member and a second protrusion that protrudes from the surface facing the base member of the first door member. A projection, a first recess for receiving the first projection on the opposite side of the second door member, a second recess for receiving the second projection on the surface of the base member facing the first door member, and a first And an elastic member that urges the second protrusion in a protruding direction, and a lock release mechanism that accommodates the first and second protrusions in the first door member against the elastic force of the elastic member.

  In one embodiment, the turning radius of the first door member is greater than the turning radius of the second door member.

  According to this invention, by arranging the two door members so as to open the doors, it is possible to obtain a baby gate that can be used even in a narrow space and is further improved in safety.

  A baby gate 11 according to an embodiment of the present invention will be described with reference to FIGS. 1 is a front view showing a closed state of the baby gate 11, FIGS. 2 and 3 are views showing a rotation interlocking mechanism, FIGS. 4 to 7 are views showing an automatic closing mechanism, and FIGS. 8 and 9 are locks. It is a figure which shows a mechanism.

  First, referring to FIG. 1, a baby gate 11 includes a base member 12 placed on a floor, and a pair of support columns 13 and 14 extending in a vertical direction from one side end and the other side end of the base member. And first and second door members 15 and 16 that are rotatably connected to the pair of support columns 13 and 14, respectively.

  Further, the baby gate 11 has a rotation interlocking mechanism for interlockingly rotating the first and second door members 15 and 16, and the first and second door members 15 and 16 are automatically closed. An automatic closing mechanism for returning and a locking mechanism for prohibiting the opening of the first and second door members 15 and 16 are provided.

  The support column 13 rotatably supports the first door member 15, and adjustment screws 13 a and 13 b are provided on the upper end portion and the lower end portion on the opposite side to the first door member 15. The adjustment screws 13a and 13b can fix the baby gate 11 to an indoor wall or the like by appropriately adjusting the length. In addition, since the support | pillar 14 is also the same structure, description is abbreviate | omitted.

  The first and second door members 15 and 16 are substantially rectangular members, and one side 15a and 16a of the first and second door members 15 and 16 are rotatably connected to the support columns 13 and 14, respectively, and face the one side 15a and 16a. The opposite sides 15b and 16b face each other to constitute a closed state. The wall surfaces of the first and second door members 15 and 16 are provided with elongated holes 15c and 16c, respectively, so that the other side can be seen through the elongated holes 15c and 16c.

  The first door member 15 is larger than the second door member 16. Specifically, the distance between the one side 15a, 16a and the opposite side 15b, 16b is long. Therefore, the opposite sides 15 b and 16 b of the first and second door members 15 and 16 face each other closer to the column 14 than the middle of the columns 13 and 14. Further, the rotation radius of the first door member 15 is larger than the rotation radius of the second door member 16.

  Next, the rotation interlocking mechanism provided in the baby gate 11 will be described with reference to FIGS. 2 and 3 are views of the base member 12 as viewed from above, FIG. 2 is a view showing a closed state, and FIG. 3 is a view showing an open state.

  First, referring to FIG. 2, the rotation interlocking mechanism includes link members 21 and 22, and end portions of link members 21 and 22 as first and second door members 15 and 16 (not shown in FIG. 2). Consists of projections 15d, 15e, 16d, and 16e for connection.

The protrusions 15 d and 15 e protrude downward from the lower surface of the first door member 15 and are arranged on the circumference of the rotation center c ₁ of the first door member 15. Similarly, the protrusions 16 d and 16 e protrude downward from the lower surface of the second door member 16 and are arranged on the circumference of the rotation center c ₂ of the second door member 16.

Protrusions 15d, 16e are on one side regions divided by the straight line _{l 1} connecting the rotation center _c 1, _{c 2} (lower side in FIG. 2), the protrusions 15e, 16d above the other side region (in FIG. 2 ).

Further, the projections 15d, 15e are disposed on the side far from the support 14 of the regions divided by the straight line _{l 2} perpendicular to the straight line _{l 1} passing through the rotation center _{c 1.} On the other hand, the protrusion 16d, 16e are arranged closer to the support 13 of the regions divided by the straight line _{l 3} perpendicular to the straight line _{l 1} passing through the rotation center _{c 2.}

Further, the link member 21 extends halfway along the base member 12 while bent so as to straddle the linear l _1, the one side end portion 21a is in contact with the projection 15d, predetermined at the other end portion 21b projections 16d The gap is provided. Similarly, the link member 22 is also disposed between the protrusions 15e and 16e.

  Next, a mechanism in which the first and second door members 15 and 16 are rotated in conjunction with this rotation interlocking mechanism will be described.

First, when shifting from the closed state (the state in FIG. 2) in the open state (state of FIG. 3), when is 90 ° rotated clockwise a first door member 15 relative to the rotation center c _1, the projections 15d with the rotation of one of the door member 15, 15e also 90 ° moves clockwise relative rotation center _{c 1.}

At this time, the projection 15 d pushes the one end 21 a of the link member 21, so that the link member 21 moves to the column 14 side along the base member 12. Then, the projection 16d pushed by the other end portion 21b of the link member 21, around the rotation center c ₂ 90 ° moved counterclockwise, the second door member 16 with respect to the rotation center c ₂ And turn 90 ° counterclockwise. Thereby, the 1st and 2nd door members 15 and 16 open a double door to the upper side of FIG.

  Similarly, when shifting from the open state (the state of FIG. 3) to the closed state (the state of FIG. 2), when the second door member 16 is rotated clockwise, the link member 21 is moved to the column 13 side. Move and rotate the first door member 15 counterclockwise.

  Thus, if the two door members 15 and 16 rotate in conjunction with each other, the baby gate 11 can be easily opened and closed.

  In the above case, the protrusion 15e moves away from the link member 22, and the protrusion 16e moves without contacting the link member 22 due to a gap provided between the link member 22 and the link member. 22 does not move. The link member 22 and the protrusions 15e and 16e are necessary when the first and second door members 15 and 16 are opened in the opposite direction (the lower side in FIG. 2).

Moreover, in this embodiment, even if the 2nd door member 16 is rotated in a closed state (state of FIG. 2), the 1st door member 15 does not interlock | cooperate. That is, the projection 16d of the driving side of the door (first door member 15) of the projections 15d, 15e outside the linear _{l 2} arranged (from post 14 far side), the driven side of the door (the second door member) by placing the 16e inside the straight line l ₃ (the side closer to the support 13), can be interlocked with two doors.

Further, the projections 15d, by arranging on the opposite side of the straight line _{l 1} and 16d, can be rotated (double doors) in the opposite direction in conjunction with the first and second door members 15 and 16. On the other hand, by arranging the projections 15d, 16d are on the same side of the straight line _{l 1,} first and second door members 15 and 16 are rotated in the same direction.

  The rotation interlocking mechanism is not limited to the above-described configuration, and any configuration that enables the first and second door members 15 and 16 to rotate in conjunction with each other can be adopted.

  Next, the automatic closing mechanism provided in the baby gate 11 will be described with reference to FIGS. 4 is an exploded view of part P in FIG. 1, FIG. 5 is a view showing a closed state, FIG. 6 is a view showing an open state, and FIG. 7 is a view showing a state further opened from the state of FIG.

  First, referring to FIG. 4, the automatic closing mechanism includes a protrusion 31 that protrudes downward in the vertical direction from the support 13, a recess 32 that is disposed on the first door member 15 and receives the protrusion 31, and the support 13. The coil spring 33 is an elastic member that is arranged between the convex portion 31 and biases the convex portion 31 in the direction of the concave portion 32.

  The convex portion 31 has a cylindrical shape, and the tip thereof is inclined at a predetermined angle with respect to the protruding direction. The bottom wall of the concave portion 32 includes an inclined surface 32a corresponding to the tip of the convex portion 31, and a flat surface 32b continuous to the top of the inclined surface 32a.

  Next, a mechanism for returning the first door member 15 from the open state to the closed state by the automatic closing mechanism will be described.

  First, referring to FIG. 5, in the closed state, the apex portion 31 a of the convex portion 31 and the innermost portion 32 c of the concave portion 32 coincide with each other, and the tip end of the convex portion 31 and the inclined surface 32 a of the concave portion 32 are located. It is in a state of surface contact.

  Next, referring to FIG. 6, when the first door member 15 is rotated to some extent (for example, 90 °), the position of the top portion 31 a of the convex portion 31 while the convex portion 31 and the concave portion 32 rotate relative to each other. Rises along the inclined surface 32 a of the recess 32. At this time, the coil spring 33 is compressed by the amount of rise of the top 31a.

  When the hand is released from the first door member 15 in the state shown in FIG. 6, the convex portion 31 is pushed down by the restoring force of the coil spring 33. Thereby, the convex part 31 and the recessed part 32 rotate relatively in the direction which closes the 1st door member 15, and the position of the top part 31a falls to the innermost part 32c along the inclined surface 32a. As a result, the first door member 15 automatically returns to the closed state. Thereby, the accident by forgetting to tighten can be prevented beforehand.

  Next, referring to FIG. 7, when the first door member 15 is rotated by a predetermined angle or more (for example, 150 °), the top portion 31 a of the convex portion 31 rises along the inclined surface 32 a of the concave portion 32, It reaches the flat surface 32b.

  At this time, the coil spring 33 is further compressed than the state shown in FIG. 6, but its restoring force acts in a direction perpendicular to the flat surface 32b. Therefore, the first door member 15 does not return to the closed state by this restoring force. Thereby, it can prevent effectively that a door closes and a child etc. are pinched during passage.

  The automatic closing mechanism may be further provided on the second door member 16. At this time, it is desirable to make the return speeds of the first door member 15 and the second door member 16 different. Thereby, it can prevent more effectively that a child etc. are pinched between the 1st and 2nd door members 15 and 16.

  As a specific method of making the return speeds of the first and second door members 15 and 16 different, the elastic force of the coil spring 33 is made different, or the frictional force between the convex portion 31 and the concave portion 32 is made different. Just do it. In this embodiment, since the first door member 15 is heavier than the second door member 16, if the same automatic closing mechanism is incorporated, the return speed of the first door member 15 is the same as that of the second door member 16. Slower than the return speed.

  Further, when combined with the above-described rotation interlocking mechanism, by incorporating the automatic closing mechanism only in the second door member 16, the two can be interlocked and automatically returned to the closed state. That is, the second door member 16 tries to return to the closed state by the automatic closing mechanism, and pushes the link members 21 and 22 toward the support column 13 to return the first door member 15 to the closed state. .

  In the above-described embodiment, the example in which the protrusion 31 is provided on the side of the support column 13 and the recess 32 is provided on the side of the first door member 15 is shown. What is necessary is just to provide the protrusion 31 in the any one side of the door member 15, and the recessed part 32 in the other side. That is, the same effect can be obtained even if the convex portion 31 is provided on the first door member 15 side and the concave portion 32 is provided on the support column 13 side.

  Furthermore, the rotation interlocking mechanism is not limited to the above configuration, and any configuration can be adopted. For example, it can be automatically returned to the closed state by disposing a torsion spring in the rotating portions of the first and second door members 15 and 16.

  Next, with reference to FIG. 8 and FIG. 9, the lock mechanism provided in the baby gate 11 will be described. FIG. 8 is a diagram showing the locked state, and FIG. 9 is a diagram showing the unlocked state.

  First, referring to FIG. 8, the first door member 15 protrudes from the opposite side 15 b so as to be able to go in and out and from the bottom surface facing the base member 12 so as to be able to go in and out. The first projection and the second projection 42, the coil spring 43 as an elastic member that urges the first and second projections 41 and 42 in the projecting direction, and the first and second projections against the elastic force of the coil spring 43. A lock release mechanism for accommodating the protrusions 41 and 42 in the first door member 15.

  Further, on the opposite side 16b of the second door member 16, a first recess 44 for receiving the first protrusion 41 is formed on the upper surface of the base member 12 (not shown in FIG. 8) facing the first door member 15. Are each provided with a second recess 45 for receiving a second protrusion.

  The lock release mechanism includes a pivot arm 52 that is pivotably attached to the first door member 15 by a pivot center 52a, and a link bar 53 that has one end attached to the pivot arm 52 and extends downward. And a release lever 54 attached to the upper portion of the first door member 15 so as to be movable to the left and right and connected to the rotating arm 52. Note that the first protrusion 41 is held on the rotating arm 52 in a rotatable state. A second protrusion 42 is attached to the lower end of the link bar 53.

  The release lever 54 is biased by the coil spring 43 in the direction in which the first and second protrusions 41 and 42 protrude (left side in FIG. 8). Release lever 54 further includes a release button 55. Furthermore, the release button 55 is provided with an insertion port 55a that can be fitted into the protrusion 15f of the first door member 15 in a pressed state.

  Next, the mechanism of this locking mechanism will be described.

  First, referring to FIG. 8, the first protrusion 41 and the first recess 44, the second protrusion 42 and the second recess 45 are engaged with each other, and the first and second door members 15 are engaged. 16 are fixed in a closed state.

  Next, referring to FIG. 9, when releasing the lock, the release lever 54 is moved to the right side in the figure against the elastic force of the coil spring 43. However, when the release button 55 is not pressed, the protrusion 15f abuts on the peripheral edge of the insertion port 55a to limit the movement of the release lever 54.

  Therefore, when the release lever 54 is moved to the right side in the drawing while the release button 55 is pressed, the turning arm 52 turns clockwise about the turning center 52a. Accordingly, the first protrusion 41 is retracted to the right side in the drawing and is accommodated in the first door member 15. Further, since the position of the connecting portion with the link rod 53 is raised, the link rod 53 is lifted and the second protrusion 42 is also accommodated in the first door member 15.

  Then, the engagement between the first door member 15 and the base member 12 and the engagement between the first door member 15 and the second door member 16 are respectively released, and the first and second door members 15, 16 will be in a rotatable state. Thus, by providing the lock member at a position out of the reach of the child, there is no risk that the child or the like will unexpectedly open the door members 15, 16, and the safety of the baby gate 11 is further improved.

  The lock mechanism is not limited to the above configuration, and any configuration that can fix the first and second door members 15 and 16 in a closed state can be employed.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
