Description

  The present invention relates to a safety fence that is installed in a passage and restricts passage of infants and pets.

  As this type of safety fence, Patent Document 1 discloses a safety fence for infants in which a sheet-like protection member (54) is attached to a frame (10). The infant safety fence is configured to be able to temporarily push down the upper projecting member (18) of the frame (10) so that a guardian can pass through the passage. The protective member (54) is formed of a flexible material so that it can be deformed when the upper strut member (18) is pushed down (see paragraph [0037]).

  Thus, although the infant safety fence described in Patent Document 1 temporarily lowers the height, for example, according to the height of the infant, the installation height (when the upper tension member is not pushed down) It is not assumed that the height will be changed. If the installation height of the infant safety fence is lowered, the protective member (54) is slackened.

  On the other hand, Patent Document 2 discloses a traffic regulation fence (1) configured such that the installation height can be adjusted and the sheet-like member (9) does not sag when the installation height is lowered. Has been. Specifically, when the installation height is lowered, the end of the sheet-like member (9) is folded back, and the fixing button (47) is fastened to the buttonhole (49), whereby the sheet-like member (9) The vertical dimension is reduced to prevent sagging (see paragraph [0022] etc.).

JP 2007-14587 A Japanese Patent No. 5137789

  However, the traffic regulation fence (1) described in Patent Document 2 requires an operation to fasten or remove the button (47) from the button hole (49) when changing the vertical dimension of the sheet-like member (9). In addition, the vertical dimension can be adjusted only in steps (up to three levels). Moreover, since the button (47) and the buttonhole (49) can be seen from the outside, it is not preferable in terms of appearance. Furthermore, it is very dangerous if the infant's neck or the like is caught on the folded portion of the sheet-like member (9).

  The present invention has been made in view of such circumstances, and it is easy to change the vertical dimension of the protective sheet (“sheet-like member” referred to in Patent Document 2), and stepless adjustment is possible. The purpose is to provide a safety fence that is excellent in beauty and less dangerous for young children.

  A safety fence according to an aspect of the present invention includes a frame having a pair of upper and lower horizontal members, and a protective sheet attached to the pair of upper and lower horizontal members, and the pair of upper and lower horizontal members has a predetermined minimum interval. The protective sheet is configured such that the vertical distance can be changed from the maximum distance to the maximum distance, and at least a part of the protective sheet is formed of a stretchable material. The vertical dimension can be changed up to the interval.

  According to this configuration, when changing the installation height of the safety fence, the vertical dimension of the protective sheet is changed by the expansion and contraction of the portion formed by the elastic material. Therefore, the vertical dimension can be easily changed, and stepless adjustment is possible. Furthermore, since a fastener or the like for changing the vertical dimension is unnecessary, the aesthetic sense is excellent. In addition, since the folded portion does not occur in the protective sheet, it is safe without the child's body being caught.

  In the safety fence, the protective sheet has a pair of upper and lower horizontal sleeves into which the pair of upper and lower horizontal members are inserted, and at least one of the pair of upper and lower horizontal sleeves is formed of the stretchable material. May be. According to such a configuration, it is sufficient that at least one horizontal sleeve is formed of an elastic material, and the safety fence can have a simple structure.

  In the safety fence, the frame includes a pair of left and right vertical members, and the protective sheet includes a pair of left and right vertical sleeves into which the pair of left and right vertical members are inserted. The horizontal sleeve portion and the pair of left and right vertical sleeve portions may be connected in an annular shape as a whole, and the pair of left and right vertical sleeve portions may be formed of a non-stretchable material. According to such a configuration, since the vertical sleeve portions corresponding to at least the right side and the left side of the protective sheet are formed of a non-stretchable material, the shape of the protective sheet is maintained even when the horizontal sleeve portion expands and contracts, and the protective sheet is distorted. Can be suppressed.

  In the safety fence, one of the pair of upper and lower horizontal sleeves may be formed of a non-stretchable material. According to such a configuration, since the horizontal sleeve corresponding to the upper side or the lower side is formed of the non-stretchable material in addition to the two vertical sleeves corresponding to the right side and the left side of the protective sheet, the distortion of the protective sheet can be further suppressed.

  The protective sheet may have a net-like sheet main body, and the sheet main body may be formed of the stretchable material. Even in this configuration, the vertical dimension of the protective sheet can be changed without using a fastener or the like, and stepless adjustment is possible.

  The frame body has a pair of left and right vertical members whose left and right intervals can be changed, and the protective sheet has a pair of left and right vertical sleeves into which the pair of left and right vertical members are inserted. At least one of the vertical sleeves may be formed of an elastic material. According to this configuration, not only the vertical dimension but also the horizontal dimension of the protective sheet can be changed without using a fastener or the like.

  According to said structure, the change of the vertical dimension of a protection sheet is easy, a stepless adjustment is possible, it is excellent in aesthetics, and also can provide the safety fence with few dangers also for an infant.

FIG. 1 is a front view of a safety fence according to an embodiment. FIG. 2 is a front view of the frame shown in FIG. Drawing 3 is a mimetic diagram of a protection sheet containing other embodiments.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Below, the same code | symbol is attached | subjected to the element which is the same or it corresponds through all the drawings, and the overlapping description is abbreviate | omitted.

  FIG. 1 is a front view of a safety fence 100 according to the present embodiment. The safety fence 100 is attached between the walls 101 (or pillars) facing each other across the passage to restrict the passage of the infant or pet through the passage. As shown in FIG. 1, the safety fence 100 includes a frame 10 and a protective sheet 30. Hereinafter, these components will be described in order.

<Frame body>
The frame 10 is a portion that hits the framework of the safety fence 100. FIG. 2 is a front view of the frame body 10. As shown in FIG. 2, the frame 10 is formed in a rectangular frame shape, and includes an upper horizontal member 11, a lower horizontal member 12, a right vertical member 13, and a left vertical member 14.

  The upper horizontal member 11 is a member that extends in the horizontal direction and forms the upper side of the frame body 10. The upper horizontal member 11 has an outer pole 15 and an inner pole 16. When the inner pole 16 is rotated in the circumferential direction with respect to the outer pole 15, the inner pole 16 moves in the outer pole 15 in the axial direction, and the length of the upper horizontal member 11 changes. The upper horizontal member 11 is attached to the left and right walls 101 via a slide socket 17 described later. If the upper horizontal member 11 is extended and both walls 101 are stretched, the upper horizontal member 11 can be fixed between the left and right walls 101.

  The above-described slide socket 17 is located on the outer side in the left-right direction with respect to the upper horizontal member 11, and is fixed to a predetermined position on the wall 101 using a double-sided tape or a screw. The slide socket 17 has a recess 18 extending in the vertical direction. The end of the upper horizontal member 11 is inserted into the recess 18, and the upper horizontal member 11 can move in the vertical direction along the recess 18. That is, the concave portion 18 serves as a guide.

  The lower horizontal member 12 is a member that extends in the horizontal direction and forms the lower side of the frame body 10. Since the lower horizontal member 12 has basically the same configuration as the upper horizontal member 11, the same reference numerals are assigned to corresponding elements, and description thereof is omitted. However, the lower horizontal member 12 is attached to the wall 101 not through the slide socket 17 but through the fixed point socket 19. The lower horizontal member 12 does not move up and down along the fixed point socket 19.

  The right vertical member 13 is a member that extends in the vertical direction and forms the right side of the frame 10. The right vertical member 13 includes a fixed pole 20 and a sliding pole 21 that can slide in the fixed pole 20. As the sliding pole 21 slides within the fixed pole 20, the right vertical member 13 expands and contracts in the vertical direction. The right vertical member 13 has a hook portion 22 at the lower end. The hook portion 22 is hooked on the lower horizontal member 12, thereby connecting the lower end of the right vertical member 13 and the lower horizontal member 12. The upper end of the right vertical member 13 is connected to the upper horizontal member 11 via a T-shaped joint member 23. The right vertical member 13 can be moved in the left-right direction while being attached to the upper horizontal member 11 and the lower horizontal member 12.

  The left vertical member 14 is a member that extends in the vertical direction and forms the left side of the frame 10. Since the configuration of the left vertical member 14 is basically the same as the configuration of the right vertical member 13, the same reference numerals are assigned to corresponding elements, and description thereof is omitted.

  The frame body 10 is configured as described above, and the installation height of the safety fence 100 can be adjusted by moving the upper horizontal member 11 in the vertical direction along the slide socket 17. When the upper horizontal member 11 is at the upper end portion (uppermost position) of the recess 18 of the slide socket 17, the vertical distance between the upper horizontal member 11 and the lower horizontal member 12 (the pair of upper and lower horizontal members 11, 12) is the maximum interval. The “vertical interval” here refers to the distance from the upper edge of the upper horizontal member 11 to the lower edge of the lower horizontal member 12. Further, when the upper horizontal member 11 is at the lower end portion (lowest position) of the recess 18 of the slide socket 17, the vertical distance between the upper horizontal member 11 and the lower horizontal member 12 is the minimum interval. As the upper horizontal member 11 moves in the vertical direction, the right vertical member 13 and the left vertical member 14 (the pair of left and right vertical members 13, 14) expand and contract in the vertical direction.

<Protective sheet>
The protection sheet 30 is a sheet attached to the frame body 10. As shown in FIG. 1, the protective sheet 30 includes a seat body portion 31, an upper horizontal sleeve portion 32, a lower horizontal sleeve portion 33, a right vertical sleeve portion 34, and a left vertical sleeve portion 35.

Further, the upper horizontal sleeve portion 32 and the lower horizontal sleeve portion 33 (the pair of upper and lower horizontal sleeve portions 32, 33) are respectively attached to the upper edge and the lower edge of the seat body portion 31. The right vertical sleeve portion 34 and the left vertical sleeve portion 35 (a pair of left and right vertical sleeve portions 34 and 35) are respectively attached to the right edge and the left edge of the seat body portion 31. Further, the upper horizontal sleeve portion 32, the lower horizontal sleeve portion 33, the right vertical sleeve portion 34, and the left vertical sleeve portion 35 are all formed in a cylindrical shape, and are respectively an upper horizontal member 11 and a lower horizontal member of the frame body 10. The member 12, the right vertical member 13, and the left vertical member 14 are inserted.

  In the present embodiment, only the lower horizontal sleeve portion 33 of the protective sheet 30 is formed of an elastic material such as synthetic rubber. And the lower horizontal sleeve part 33 is comprised so that it may expand / contract to the same or larger than the moving distance from the lowest position of the upper horizontal member 11 to the highest position. That is, the protective sheet 30 is configured such that the vertical dimension can be changed from the minimum interval to the maximum interval between the upper horizontal member 11 and the lower horizontal member 12 by expansion and contraction of the lower horizontal sleeve portion 33. Therefore, according to the safety fence 100 according to the present embodiment, the vertical dimension of the protective sheet 30 can be changed without using a fastener or the like. Therefore, the vertical dimension of the protective sheet 30 can be easily changed, and stepless adjustment is possible, which is excellent in aesthetics. Further, since the folded portion does not occur when the vertical dimension of the protective sheet 30 is reduced, the infant is safe without being caught by the folded portion.

  Moreover, in this embodiment, the sheet | seat main-body part 31, the upper horizontal sleeve part 32, the right vertical sleeve part 34, and the left vertical sleeve part 35 among the protective sheets 30 are formed with non-stretchable materials, such as a synthetic fiber. Further, the upper horizontal sleeve portion 32, the lower horizontal sleeve portion 33, the right vertical sleeve portion 34, and the left vertical sleeve portion 35 are connected in an annular shape so as to surround the seat body portion 31. Therefore, even if the lower horizontal sleeve portion 33 expands and contracts when changing the vertical dimension of the protective sheet 30, the sleeve portions 32, 34, and 35 corresponding to the upper side, the right side, and the lower side of the protective sheet 30 do not expand and contract. Can suppress distortion. That is, since the protective sheet 30 of this embodiment has a small change in shape before and after the change in the vertical dimension, a more excellent aesthetic feeling can be obtained.
