Description

  TECHNICAL FIELD The present invention relates to a protective fence used in a child facility such as a nursery school or a kindergarten, a home, or the like when an enclosure space is provided and an infant is allowed to play therein.

  Conventionally, as this type of protective fence, a self-supporting L-type type composed of two fence-like segments is known. On the other hand, a type of circle that surrounds the four sides with four-sided fence-like segments is also used.

  However, in the former case, when not in use, it must be folded and moved to another place and stored separately. The work had to be done, and the troublesome work was required.

  In addition, since the latter has the same weakness as the former, it has a configuration in which four fence-like segments are connected, so when folded, its size and weight are almost doubled, and the cost is high. There were disadvantages such as.

  Furthermore, the former often is fixed to a fixed object with screws or the like. For this reason, when it is no longer used, there is a problem that not only is a troublesome operation requiring a gap for removing a screw or the like, but also the trace remains and is conspicuous. Also, sometimes disassembly / reassembly work such as temporarily removing the hinges is required. In addition, when storing a large number of units in a warehouse or the like, time-consuming and expensive work of carrying and storing by a large number of people has occurred.

  In view of the above circumstances, the present invention is so-called in a state of being attached to the inside of a fixed object such as a two-sided wall or a fixed panel that forms a corner of a room without being removed when not in use. The purpose is to solve the various weaknesses and problems as described above at once by giving a device that does not get in the way by a simple operation of pressing and placing.

  In order to achieve the above-mentioned object, the protective fence according to claim 1 is configured such that a pair of fence segments having the same length are rotatably connected, and both ends thereof are attached to a fixed part on two surfaces forming a corner. Affixed to the at least one fence segment to form a bendable part, and when the other fence segment is rotated at a right angle inward, the one fence segment is also linearly attached to one surface of the fixed object. It is characterized by touching.

  The protective fence according to claim 2 is characterized in that the mounting portion is a mounting plate.

The protection fence 10 according to this embodiment is configured to be foldable in two by connecting a pair of fence segments 11a and 11b having the same length with a hinge 12, and a fixed object, for example, a room 13 is provided at both ends thereof. Mounting plates 15a and 15b for fixing to the two walls 14a and 14b forming the corner 13a are provided.

  Each of the fence segments 11a and 11b has a rectangular frame shape when viewed from the front, and a plurality of vertical rails 17 are provided between the upper and lower side members 16a and 16b, and the upper and lower side members 16a. A pair of prismatic members 19a and 19b are fixed for connection between the connection side ends 18a and 18b of 16b. One prism member 19a has a rectangular cross section, and the other prism member 19b has a square cross section. The upper and lower ends of the mounting plates 15a and 15b are pivotally attached to the mounting side ends 20a and 20b of the upper and lower side members 16a and 16b by vertical support shafts 21, and the fence segments 11a and 11b are the same. It is supported so as to be rotatable about the support shaft 21.

  The fence segment 11a to which the rectangular columnar member 19a having a rectangular cross section is fixed is provided with a foldable portion 23 formed by being connected by a hinge 22 at a middle vertical line portion, and is folded in two. It is used as a free pull side fence segment. In addition, the fence segment 11b to which the square prism member 19b is fixed is configured so as not to be folded in half, and is used as a push-side fence segment.

  A plurality of the bendable portions 23 can be provided on one fence segment or on both fence segments. Moreover, you may make it press both the wall segments 14a and 14b and tidy up by making the connection part separable and reconnectable structure, without providing the bendable part 23. FIG.

  The pull-side fence segment 11a is provided with a locking device 24 for holding the portion 23 in a state where it cannot be bent temporarily outside the bendable portion 23. The locking device 24 includes a pin-shaped receiving body 26 having a large head portion 25 at the tip end, and a hanging body 28 having a notch 27 hooked on the receiving body 26 at the tip end portion. When the notch 27 is hung on the receiving body 26 by turning the shaft 28 around the support shaft 29, the bendable portion 23 is held in a state where it cannot be folded in half, and when turned in the opposite direction, it is released to release the hold. It is like that. Examples of such a locking device include a structure using a retaining pin that can be detached and attached by an insertion / removal operation, and a structure with a key for preventing mischief.

  Further, as shown in FIG. 5, the push-side fence segment 11b has a concave central portion on the upper side so that an adult can straddle it while holding a child. A handrail 31 is provided at the concave entrance 30 as an open / close type. The handrail 31 is provided with a stopper (not shown) for holding it in a closed state, but since it is not the gist of the present invention, detailed description thereof is omitted here.

  In FIGS. 1 and 2, reference numeral 32 denotes a shaving for smooth operation of the pull-side fence segment 11a and push-side fence segment 11b, and specifically for enabling the hinge 12 to function without trouble. It is the dropped inclined surface part. Reference numeral 33 denotes a caster for facilitating the operation of the pull side fence segment 11a and the movement of the push side fence segment 11b.

  That is, the protection fence 10 of this embodiment is first self-supported near the two walls 14a and 14b forming the corner 13a of the room 13. Thereafter, both the mounting plates 15a and 15b are aligned with the walls 14a and 14b by being moved using the casters 33 in the self-supporting state, and the walls 14a and 14b are respectively aligned with the walls 14a and 14b. The mounting plates 15a and 15b are fixed. Therefore, it is possible to form the enclosure space 34 including the two walls 14a and 14b as a part. When the enclosure space 34 is not used, the pull-side fence segment 11a is attached as described below. After pulling out, the push-side fence segment 11b is pushed and cleaned up.

  In other words, the protective fence 10 of the above embodiment can easily and easily fix the mounting plates 15a and 15b, that is, the assembling work by the self-supporting property and the caster movement. Moreover, the pull-out operation of the pull-side fence segment 11a and the push-side fence segment can be performed. Since the pressing operation of 11b can be performed easily and easily, the above-mentioned weak points and problems can be solved all at once.

  Next, the pull-out operation of the pull side fence segment 11a and the push operation of the push side fence segment 11b will be described.

  When the enclosure space 34 is formed, first, the locking device 24 is removed, and then the bendable portion 23 is pulled out in the direction of the arrow A shown in FIG. The push-side fence segment 11b moved by pulling is pushed in the direction of arrow B shown in FIG. 3 to the state shown in FIG. 6, and finally the connecting portion between the pull-side fence segment 11a and the push-side fence segment 11b is shown by the arrow C shown in FIG. Then, the enclosure space 34 shown in FIG. If the enclosure space 34 is required, first pull the pull-side fence segment 11a slightly in the direction opposite to the arrow C, and then pull the push-side fence segment 11b in the direction opposite to the operation of the arrow D. The pulling side fence segment 11a may be stopped when it becomes linear, and finally the locking device 24 may be hung to the state shown in FIGS.

  Here, FIG. 8 will be described. FIG. 8 is obtained by trying to verify the position where the bendable portion 23 can be provided by drawing by CAD, and shows the auxiliary line included.

  FIG. 8 shows the bendable portion 23 when the pull-side fence segment 11a rotates horizontally, that is, the bending points 1a to 1e, and the connection end or connection points 2a to 2e when the push-side fence segment 11b rotates horizontally. And a fifth dividing point 3a (bisected position) from the support shaft 20a, a fourth dividing point 3b, a third dividing 3c, Lines 4a to 4e are schematic views showing five theoretical partitioning devices assuming the bendable portion 23 at the second dividing point 3d and a third point 3e. ing. Note that the thickness of the material is not taken into consideration.

Line 4a: A protective fence provided with a bendable portion at the fifth dividing point 3a (bending point 1a).
Line 4b: A protective fence provided with a bendable part at the fourth dividing point 3b (bending point 1b) is shown.

The protection fence which provided the bending | flexion free part in the point 3e (bending point 1e) of line 4e; 1/3 (1/3 from the spindle 20a of the pulling side fence segment 11a) is shown.

Line 4a shows the protection fence of the above-described embodiment. The connecting point 2a is located on the locus line 5 at the connecting end of the push-side fence segment 11b, and the bending point 1a is in contact with the wall 14a. Not. Therefore, the operations indicated by the arrows A and B are possible.
In the line 4b, the connection point 2b is located on the locus line 5, and the bending point 1b is not in contact with the wall 14a. Therefore, the operations indicated by the arrows A and B are possible.
In the line 4c, the connecting point 2c is located on the locus line 5, and the bending point 1c is in contact with the wall 14a. Therefore, the operations indicated by the arrows A and B are impossible.
In the line 4d, the connecting point 2d is located on the locus line 5, and the bending point 1d is in contact with the wall 14a. Therefore, the operations indicated by the arrows A and B are impossible.
In the line 4e, the connecting point 2e is located on the locus line 5, and the bending point 1e is in contact with the wall 14a. Therefore, although the operation indicated by the arrow A is in a state of being restricted, the operation indicated by the arrow B is possible because it is a straight line from the attachment end 20b.

  For these reasons, when the bendable portion 23 is provided at a position larger than the third, the operations of the arrows A, B, C, and D are possible, but it is provided at a position smaller than this. In this case, it can be seen that the wall 14a is disturbed to enter a locked state.

  Accordingly, the portion where the bendable portion 23 is provided should be provided at a position larger than one third from the attachment side 20a so as not to be locked.

  FIG. 9 will be described. This FIG. 9 is obtained by trying to verify the case where the bendable portion 23 is provided at a position larger than the position of the bisection point 2a from the mounting end side 20a by drawing by CAD, and the auxiliary line is included. Show.

  FIG. 9 shows the bendable portion 23 when the pull-side fence segment 11a rotates horizontally, that is, the bending points 6f to 6h, and the connection end when the push-side fence segment 11b rotates horizontally, that is, the connection points 7f to 7h. It is the plot which is shown, and the theoretical assumption which assumed the attachment end which divided | segmented the pull side fence segment 11a into 10 divisions, ie, the 7th division point 8f, the 8th division point 8g, and the 9th division 8h from the attachment side end 20a. The state of the three types of protective fences as viewed from above is schematically represented by lines 9f to 9h. Note that the thickness of the material is not taken into consideration.

Line 9f: A protective fence provided with a bendable portion at the seventh dividing point 7f (folding point 6f).
Line 9g: A protective fence provided with a bendable portion at the eighth dividing point 8g (folding point 6g).
Line 9h: A protective fence provided with a bendable portion at the ninth dividing point 9h (folding point 6h).

  The lines 9f to 9h indicate the state in which the operation of the arrow A is performed. From the lines 9f to 9h, the following is possible.

  That is, the bending points 6f to 6h do not contact the wall 14a, and the operations of the arrows A, B, C, and D are possible.

  However, in the implementation, the case where the dividing point is set to the half-divided position (dividing point 3a) of the pulling side fence segment 11a is the most preferable because it is most easy to manufacture.

  In the embodiment described above, the wooden horizontally long frame-like body having vertical bars is used as each fence segment in the above-described embodiment, but the present invention can also be implemented by using plastic, metal, or other fence segments.
