Description

  The present invention relates to an unlocking prevention tool that prevents a door lock from being opened.

  As a conventional unlocking prevention tool, for example, there is one described in Patent Document 1. The unlocking prevention tool described in this document includes a box fixed to a door provided with a thumb turn, and a rod-shaped stopper protruding upward from the box. The box is fixed at a predetermined position of the door so that the tip of the stopper comes into contact with the thumb turn to be rotated from the front in the rotational direction.

JP 2005-23770 A

  According to the above-described unlocking prevention tool, since the rotation of the thumb turn is blocked by the stopper, it is possible to prevent the lock from being illegally opened. However, this unlocking prevention tool has a problem that the positioning at the time of attachment to the door is troublesome. That is, it is necessary to finely adjust the position of the stopper with respect to the thumb turn so that the thumb turn can be prevented from rotating.

  The present invention has been made in view of the above problems, and an object thereof is to provide an unlocking prevention tool that can be easily aligned when attached to a door.

  An unlocking prevention device according to the present invention is an unlocking prevention device attached to a door provided with a thumb turn, and is a plate-like member constituting a box body whose upper surface is opened by being bent along a predetermined folding line. The box is fixed to the door so as to cover the thumb turn, and the bottom of the box has a hole that fits the knob of the thumb turn.

  In this unlocking prevention tool, a box is obtained by folding the plate-shaped member along the fold line. There is a hole in the bottom of the box. When the thumb-turn knob is fitted in this hole, rotation of the thumb-turn is prevented, so that the lock can be prevented from opening. Moreover, the unlocking prevention tool can be attached to the correct position simply by covering the thumb turn with a box so that the thumb turn knob fits into the hole in the bottom. For this reason, alignment at the time of attachment to a door can be performed easily.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted.
(First embodiment)

  FIG. 1 is a plan view showing a first embodiment of an unlocking prevention device according to the present invention. The unlocking prevention tool 1 is an unlocking prevention tool that prevents the lock of the door from opening, and is attached to a door provided with a thumb turn. In detail, the unlocking prevention tool 1 is an assembly-type unlocking prevention tool, and is attached to a door after an assembly. FIG. 1 shows an unlocking prevention tool 1 before assembly.

  2 and 3 are a perspective view and a plan view, respectively, showing the unlocking prevention device 1 after assembly. However, in FIG. 3, illustration of reinforcing regions 181 and 182 described later is omitted. 4 and 5 are end views taken along lines IV-IV and VV in FIG. 3, respectively.

  As shown in FIG. 1, the unlocking prevention tool 1 includes a plate-like member 100. The plate member 100 is made of cardboard. The plate-like member 100 has a flat sheet shape and is formed from a single cardboard. The plate-like member 100 constitutes the box 10 shown in FIGS. 2 to 5 by being bent along a predetermined fold line (a mountain fold line and a valley fold line described later). It is preferable that a crease line is formed in advance in the fold line so that the plate member 100 can be easily bent along the fold line. In the present embodiment, the box 10 is composed of only one plate-like member 100.

  The box 10 has a bottom part 12 and a side part 14. In the present embodiment, the bottom 12 is rectangular in plan view. Accordingly, the side surface portion 14 is composed of four flat plates standing from each of the four sides of the bottom portion 12. The upper surface of the box 10 is open. The length of each side of the opening is, for example, about 4 to 8 cm.

  As will be described later, the box 10 is fixed to the door so as to cover the thumb turn. Specifically, the box 10 is fixed to the door by fixing the edge 16 of the box 10 on the upper surface (opening surface) to the door. In the present embodiment, the edge portion 16 is provided with an adhesive means (not shown) having an adhesive force with respect to the door. The edge portion 16 can be attached to the door plate via the adhesive means. As the adhesive means, for example, an adhesive tape or an adhesive gel can be used. The edge 16 extends to the outside of the side of the box 10. That is, the edge portion 16 is provided so as to protrude from the upper end of the side surface portion 14 toward the outside of the box body 10.

  The bottom 12 of the box 10 has a hole 20 that fits into the thumb turn knob. The hole 20 may be fitted to the thumb turn knob without any gap, or may be fitted with a gap. In the present embodiment, the hole 20 has an elongated rectangular shape in plan view (see FIG. 3). The length of the long side of the hole 20 is, for example, about 3 to 4 cm. Moreover, the length of the short side of the hole 20 is about 0.5 to 1.5 cm, for example. The hole 20 is located at the center of the bottom portion 12. The hole 20 passes through the bottom 12.

  It is preferable that the unlocking prevention tool 1 is detachable with respect to the door. Here, detachable means that the unlocking prevention tool 1 can be easily attached to and detached from the door without fouling the door and the unlocking prevention tool 1. For example, when the unlocking prevention tool 1 is attached to the door using a screw, the door is damaged by the screw hole, and thus it cannot be said that the unlocking prevention tool 1 is detachable.

  Returning to FIG. 1, the plate-like member 100 includes bottom regions 121 to 123, side surface regions 141 to 144, and edge regions 161 to 164.

At this time, the tongue piece 181 b enters the inside of the hole 20. In addition, the side part area | region 141 is fixed to each side part area | region 143,144 using an adhesive tape etc. FIG.

  Finally, the valley fold line V16 is folded 180 degrees so that the reinforcing region 182 is folded back onto the side surface region 142. Further, the mountain fold lines M16a and M16b are folded at a substantially right angle. Thereafter, the valley fold line V11b is valley-folded at a right angle so that the side surface region 142 occurs with respect to the bottom region 121. Further, the mountain fold line M14b is folded at a right angle. As a result, the remaining portion of the bottom 12 (the portion not covered with the reinforcing region 181) is covered with the reinforcing region 182. At this time, the tongue piece 182 b enters the inside of the hole 20. The side surface region 142 is fixed to the side surface regions 143 and 144 using an adhesive tape or the like. The unlocking prevention tool 1 is obtained by the above.

  An example of a method for using the unlocking prevention tool 1 will be described with reference to FIGS. FIG. 9 shows a door 90 to which the unlocking prevention tool 1 is attached. The figure shows the surface of the inside of the door 90 (inside the room). A thumb turn 92 is provided on the door 90. In order to attach the unlocking prevention tool 1, the box 10 may be fixed to the door so as to cover the entire thumb turn 92 as shown in FIG. At this time, as shown in FIGS. 11 and 12, the knob 93 of the thumb turn 92 is fitted into the hole 20. FIG. 11 is an enlarged view showing the unlocking prevention tool 1 attached to the door 90. 12 is an end view taken along line XII-XII in FIG. However, in FIG. 12, the bottom 12 is shown in a simplified manner for easy viewing. Thus, in the door 90 to which the unlocking prevention tool 1 is attached, the rotation of the knob portion 93 is restricted by the hole 20. For this reason, the rotation of the thumb turn 92 is prevented and the lock cannot be opened.

  The effect of the unlocking prevention tool 1 will be described. In the unlocking prevention tool 1, the box 10 is obtained by bending the plate-like member 100 along the fold line. There is a hole 20 in the bottom 12 of the box 10. When the thumb turn knob is fitted into the hole 20, rotation of the thumb turn is prevented, so that the lock can be prevented from opening. Moreover, the unlocking prevention tool 1 can be attached to the correct position simply by covering the thumb turn with the box 10 so that the thumb turn knob is fitted into the hole 20 of the bottom portion 12. For this reason, alignment at the time of attachment to a door can be performed easily. Therefore, the unlocking prevention tool 1 with which positioning at the time of attachment to the door is easy is realized.

  In the unlocking prevention tool 1, the box 10 is obtained by assembling the plate-like member 100. Therefore, the unlocking prevention tool 1 before assembly has a planar shape. For this reason, the unlocking prevention tool 1 is hard to be bulky at the time of accommodation or conveyance.

  Further, the unlocking prevention tool 1 is attached to the door so as to cover the thumb turn with the box 10. Thereby, the range where the unlocking prevention tool 1 in a door is attached can be limited to the comparatively narrow area | region of thumb turn vicinity. If the attachment range of the unlocking prevention tool 1 can be limited to a narrow area near the thumb turn, other structures (door knobs, door chains, etc.) provided on the door will become an obstacle when the unlocking prevention tool 1 is attached. There is an advantage that it is difficult.

  When the unlocking prevention tool 1 can be attached to and detached from the door, there is no fear of soiling the door, so the unlocking prevention tool 1 can be used easily in rental housing and on the go. For example, even if you are worried about the security of the door at your travel destination, you can avoid the situation where the door is unlocked from the outside of the door by attaching the unlocking prevention device 1 to the inside of the door. Can do.

  The box 10 is fixed to the door by the edge 16 being fixed to the door. Thus, by using a part (edge 16) of the box 10 as a fixing surface to the door, the box 10 can be fixed to the door without using a fixing attachment. Thereby, the unlocking prevention tool 1 of a simple structure is realizable. In fact, in this embodiment, the unlocking prevention tool 1 consists only of the box 10 (plate-like member 100).

  Adhesive means are provided on the edge 16 (edge areas 161 to 164). By providing the adhesive means in advance as described above, the box body 10 can be fixed to the door without separately preparing a means for fixing the box body 10 to the door.

  The edge 16 extends to the outside of the side of the box 10. Thereby, the area of the edge part 16 can be enlarged. As described above, by increasing the area of the edge portion 16 serving as a fixing surface to the door, the box body 10 can be easily fixed firmly to the door.

  The hole 20 passes through the bottom 12. For this reason, when attaching the unlocking prevention tool 1, the thumb turn covered with the box body 10 can be seen through the hole 20 even from the outside of the box body 10. Thereby, since it becomes easy to align the thumb turn knob portion with the hole 20, the alignment at the time of attaching the unlocking prevention tool 1 is further facilitated.

  The opening area 131 is provided with a flap portion 131a. In this case, since the contact area of the hole 20 with the thumb turn knob is larger than when the flap portion 131a is not provided, rotation of the thumb turn can be more reliably prevented. However, it is not essential to provide the flap part 131a.

  The plate member 100 has a bottom region 122 in addition to the bottom region 121, and is bent so that the bottom region 122 overlaps the bottom region 121 in plan view. In this case, the thickness of the bottom portion 12 and thus the depth of the hole 20 can be increased as compared with the case where the bottom region 122 is not provided. Thereby, the contact area of the hole 20 with respect to the thumb turn knob is increased, and the rotation of the thumb turn can be more reliably prevented.

  In the box 10, the bottom region 121 and the bottom region 122 are separated from each other. In this case, the thickness of the bottom portion 12 and thus the depth of the hole 20 can be further increased as compared with the case where the two are not separated from each other.

  The opening region 132 is provided with a flap portion 132a. In this case, since the contact area of the hole 20 with the thumb turn knob is larger than when the flap portion 132a is not provided, rotation of the thumb turn can be more reliably prevented. However, it is not essential to provide the flap part 132a.

  The plate-like member 100 has a bottom region 123 in addition to the bottom regions 121 and 122, and is bent so that the bottom region 123 overlaps the bottom regions 121 and 122 in plan view. In this case, compared with the case where the bottom region 123 is not provided, the thickness of the bottom portion 12 and thus the depth of the hole 20 can be increased.

  In the opening region 133, a flap portion 133a is provided. In this case, since the contact area of the hole 20 with the thumb turn knob is larger than when the flap portion 133a is not provided, rotation of the thumb turn can be more reliably prevented. However, it is not essential to provide the flap part 133a.

  The plate-like member 100 has side surface regions 141 to 144 that are connected to each side of the bottom region 121. With this configuration, it is possible to easily form the side surface portion 14 including the side surface portion regions 141 to 144 only by bending the plate member 100 along each side of the bottom region 121.

  The plate-like member 100 has edge regions 161 to 164. This makes it easy to increase the area of the edge 16. Thus, by increasing the area of the edge 16 serving as a fixing surface to the door, the box 10 can be firmly fixed to the door as described above.

  The plate member 100 has a point-symmetric shape. Thereby, the beauty | look of the plate-shaped member 100 can be improved. Further, since the symmetric operation increases at the time of assembly, the assembly work is simplified. For example, in the above assembling method, a series of operations from folding the bottom region 122 on the side region 144 to overlapping with the bottom region 121, and folding the bottom region 123 on the side region 143 and then bottom A series of operations up to overlapping with the regions 121 and 122 is symmetrical.

  The plate-like member 100 has reinforcing regions 181 and 182. Thereby, in the box 10, since the bottom part 12 is covered with the reinforcement area | regions 181 and 182, the intensity | strength of the bottom part 12 can be raised.

  The box 10 is configured only by the plate-like member 100. In this case, unlike the case where the box 10 is composed of a plurality of parts provided separately from each other, there is an advantage that there is no fear of losing a part of the parts.

The plate member 100 is made of cardboard. Thereby, since it becomes easy to bend the plate-shaped member 100, the assembly of the unlocking prevention tool 1 becomes easy.

Then, the valley fold lines V11a, V11b, V11c, and V11d are folded at a right angle so that the side surface regions 141 to 144 occur with respect to the bottom region 121. Further, the mountain fold lines M14a, M14b, M14c, and M14d are folded at a right angle. Thereby, as shown in FIG. 26, it will be in the state which the side part area | regions 141-144 stood up.

  Next, the valley fold lines V21 and V22 are folded at a right angle while the slit 211a of the fixed region 211 and the slit 212a of the fixed region 212 are engaged. Similarly, the valley fold lines V24 and V25 are valley-folded at right angles while the slit 214a of the fixed region 214 and the slit 215a of the fixed region 215 are engaged. Thereby, as shown in FIG. 27, the side surface region 141 and the side surface region 142 are fixed to each other via the fixed regions 211, 212, 214, and 215.

  Subsequently, the mountain fold lines M43a, M43b, M43c, and M43d of the sub-plate member 400 are folded at a right angle. Thereafter, the sub-plate member 400 is placed in the plate-shaped member 300 assembled in a box shape so that the side contact regions 431, 432, 433, and 434 are in contact with the inner surfaces of the side surface regions 141, 142, 143, and 144, respectively. Put in. At this time, the sub-bottom region 410 is set to be parallel to the bottom region 121. The unlocking prevention tool 3 is obtained by the above.

  The effect of the unlocking prevention tool 3 will be described. In the unlocking prevention tool 3, the box 10 is obtained by bending the plate-like member 300 along the fold line. There is a hole 20 in the bottom 12 of the box 10. When the thumb turn knob is fitted into the hole 20, rotation of the thumb turn is prevented, so that the lock can be prevented from opening. Moreover, the unlocking prevention tool 3 can be attached to the correct position simply by covering the thumb turn with the box 10 so that the thumb turn knob is fitted in the hole 20 of the bottom portion 12. For this reason, alignment at the time of attachment to a door can be performed easily. Therefore, the unlocking prevention tool 3 with which positioning at the time of attachment to the door is easy is realized.

  In the unlocking prevention tool 3, a sub-plate member 400 having a sub-bottom region 410 constituting the upper surface of the bottom 12 is provided. In this case, the thickness of the bottom portion 12 and thus the depth of the hole 20 can be increased as compared with the case where the sub-plate member 400 is not provided. Thereby, the contact area of the hole 20 with respect to the thumb turn knob is increased, and the rotation of the thumb turn can be more reliably prevented.

  The sub-plate member 400 is provided separately from the plate member 300. As a result, the sub-plate member 400 can move up and down in the box 10. That is, the distance d1 (see FIGS. 24 and 25) from the bottom 12 to the upper surface (opening surface) in the box 10 is variable. For this reason, by adjusting the distance d1 according to the thickness of the base portion of the thumb turn (distance from the door plate to the knob), the unlocking prevention tool 3 is adapted to various thumb turns having different base thicknesses. be able to.

  The opening area 420 is provided with a flap portion 420a. In this case, since the contact area of the hole 20 with the thumb turn knob is larger than when the flap portion 420a is not provided, rotation of the thumb turn can be more reliably prevented. However, it is not essential to provide the flap part 420a.

  A fixed region 214 and a fixed region 215 are connected to the side surface region 141 and the side surface region 142, respectively. In the box 10, the side surface region 141 and the side surface region 142 are fixed to each other by engaging the slit 214 a of the fixed region 214 and the slit 215 a of the fixed region 215 with each other. Thereby, even if it does not use an adhesive tape etc., the state which the side part area | region 141 and the side part area | region 142 stood up can be maintained reliably.

  In the box 10, the fixed region 214 and the fixed region 215 overlap the outer surface of the side surface region 144. Accordingly, the side surface region 144 is supported from the outside by the fixing regions 214 and 215. For this reason, the state in which the side surface region 144 is erected can be reliably maintained.

  The plate-like member 300 has a line symmetrical shape. Thereby, the beauty of the plate-like member 300 can be enhanced. Further, since the symmetric operation increases at the time of assembly, the assembly work is simplified. Other effects of the unlocking prevention tool 3 are the same as those of the unlocking prevention tools 1 and 2.

  The present invention is not limited to the above embodiment, and various modifications can be made. In the said embodiment, the case where the adhesion means was provided in the edge part 16 (edge area | region 161-164 etc.) of the box 10 was illustrated. However, a magnet may be provided instead of or together with the adhesive means. In that case, the edge 16 can be fixed to the steel door plate by the magnetic force of the magnet.

  In the said embodiment, the case where the plate-shaped member 100,200,300 consists of cardboard was illustrated. However, as the material of the plate-like members 100, 200, and 300, materials other than cardboard may be used as long as they can be bent and have rigidity enough to maintain the shape after bending. An example of such a material is plastic.

  In the said embodiment, the case where the cut line was previously given to each score line was illustrated. However, it may be configured such that a cut is made in the cut line only when a force is applied to both sides of the cut line. Such a configuration can be realized, for example, by forming a perforation on a score line.

  In the said embodiment, the case where the planar shape of the hole 20 was a rectangle was illustrated. However, the planar shape of the hole 20 is arbitrary as long as the rotation of the thumb turn can be restricted. For example, the hole 20 may have a cross shape in plan view as shown in FIG. In the figure, the hole 20 includes a rectangular portion 22a (first rectangular portion) and a rectangular portion 22b (second rectangular portion). The rectangular portion 22a has the first direction (the left-right direction in the figure) as the longitudinal direction. On the other hand, the rectangular portion 22b has a second direction (vertical direction in the figure) perpendicular to the first direction as a longitudinal direction. The rectangular portion 22a and the rectangular portion 22b have different lengths. Specifically, the length of the rectangular portion 22a is larger than the length of the rectangular portion 22b. The rectangular portion 22a and the rectangular portion 22b have different widths. Specifically, the width of the rectangular portion 22a is larger than the width of the rectangular portion 22b.

  In such a configuration, there is an advantage that the direction in which the unlocking prevention tool is attached can be selected. That is, the unlocking prevention tool is attached so that the longitudinal direction of the rectangular portion 22a is parallel to the knob portion of the thumb turn, or the unlocking prevention tool is attached so that the longitudinal direction of the rectangular portion 22b is parallel to the knob portion. Is also possible. Thereby, the freedom degree of attachment of an unlocking prevention tool improves. Further, since the rectangular portion 22a and the rectangular portion 22b have different lengths, the unlocking prevention tool can be adapted to various thumb turns having different lengths of the knobs. Similarly, since the rectangular part 22a and the rectangular part 22b have different widths, the unlocking prevention tool can be adapted to various thumb turns having different widths of the knobs.

  In the said embodiment, the case where only one hole 20 was provided in the bottom part 12 was illustrated. However, the bottom 12 may be provided with a plurality of holes 20 as shown in FIG. In that case, at least two of the plurality of holes 20 may have different lengths. Further, at least two of the plurality of holes 20 may have different widths. In FIG. 29, three holes 20 are provided. In the figure, the length and width of the hole 20 located in the middle are larger than the length and width of the hole 20 located at the top. Further, the length and width of the hole 20 positioned at the bottom are larger than the length and width of the hole 20 positioned at the center.

  In the case of such a configuration, there is an advantage that the position where the unlocking prevention tool is attached can be selected. That is, it is possible to attach an unlocking preventive tool so that the thumb turn knob fits into the uppermost hole 20, or to attach an unlocking preventive tool so as to fit into the middle hole 20. It is also possible to attach an unlocking prevention tool so as to be fitted into the hole 20 of the opening. Thereby, the freedom degree of attachment of an unlocking prevention tool improves. In addition, when at least two of the plurality of holes 20 have different lengths, the unlocking prevention tool can be adapted to various thumb turns having different knob lengths. Similarly, when at least two of the plurality of holes 20 have different widths, the unlocking prevention device can be adapted to various thumb turns having different knob widths.

  In the above embodiment, the unlocking prevention tool may include a sub-plate member 500 (second sub-plate member) shown in FIG. The sub-plate member 500 is provided separately from the plate members 100, 200, and 300. The sub-plate member 500 has a strip shape. As the material of the sub-plate member 500, for example, cardboard can be used. In the sub-plate member 500, valley fold lines V51a, V51b, V51c, V51d are provided. These valley fold lines V51a, V51b, V51c, V51d are orthogonal to the longitudinal direction of the sub-plate member 500. The interval between the valley fold line V51a and the left end of the sub-plate member 500, the interval between the valley fold line V51b and the valley fold line V51c, and the interval between the valley fold line V51d and the right end of the sub-plate member 500 are all short of the holes 20. It is approximately equal to the side length. The interval between the valley fold line V51a and the valley fold line V51b and the interval between the valley fold line V51c and the valley fold line V51d are both substantially equal to the length of the long side of the hole 20.

  As shown in FIG. 31, the sub-plate-like member 500 is formed into an annular shape by being bent along predetermined fold lines (valley fold lines V51a, V51b, V51c, V51d). As shown in FIG. 32, the sub-plate-like member 500 bent in an annular shape is arranged without a gap along the inner peripheral surface of the hole 20 and is fitted to the thumb-turn knob 93. Thus, by attaching the unlocking prevention tool to the door in a state where the sub-plate-like member 500 is disposed in the hole 20, the sub-plate-like member 500 is interposed between the hole 20 and the knob portion 93. . By using the sub-plate member 500, the size of the gap between the hole 20 and the knob portion 93 can be adjusted. For this reason, the unlocking prevention tool can be adapted to various thumb turns having different sizes of the knobs.
