In fields such as home appliances, industrial equipment, and amusement equipment, it may be required that the trace of removing the fixture is known when the fixture for sealing is removed.
This invention is made | formed in view of the problem mentioned above, The objective is to provide the fixing tool which can leave the removed trace.

  The invention according to claim 1, which has been made to solve the above-described problem, includes a first protruding piece and a second protruding piece that are plate-like members protruding in the same direction. And a fracture region that is thinner than the surroundings, and is a fixture that holds the through holes formed on the main surfaces of the second projecting pieces side by side so as to form a single continuous hole. Is a fixture characterized by being formed.

The fixture configured in this way can hold the first projecting piece and the second projecting piece in an overlapped state in that state.
In addition, the fixture is formed with a fracture region that is thinner than the surroundings. Since the fracture region is thinner than the surrounding area, the fracture occurs when a force is applied to the fixture. As a result, when the fixture is removed, a trace in which the fracture area is broken remains, so that it is possible to easily confirm whether or not the fixture has been removed simply by looking at the fixture.

  According to a second aspect of the present invention, there is provided the fixing device according to the first aspect, wherein the fixing member is a columnar member, and a shaft member in which a projecting portion projecting to the outer peripheral side is formed at one end thereof; It has an insertion hole into which the other end can be inserted, and when the other end of the shaft member is inserted into the insertion hole, the shaft member engages with the shaft member and prevents the shaft member from coming out of the insertion hole. An engagement member, and the breakage region is formed between a region of the shaft member that engages with the engagement member and the protruding portion, and is inserted into the continuous hole. By holding the first projecting piece and the second projecting piece between the projecting portion of the shaft member and the engaged member engaged with the shaft member, the superposition state can be maintained. It is characterized by doing.

In the fixture configured as described above, the first projecting piece and the second projecting piece can be held in an overlapped state by the protruding portion of the shaft member and the engaged member.
And since the fracture | rupture area | region is formed between the area | region engaged with the to-be-engaged member in a shaft member, and the overhang | projection part, when force is applied to a fixing tool and a fracture | rupture area | region fractures, the said area | region The overhanging part is separated. As a result, it is possible to easily confirm whether or not the fixture has been removed simply by looking at the shaft member of the fixture. Further, when the shaft member is separated as described above, the shaft member cannot be reused. That is, since the first protruding piece and the second protruding piece cannot be held in an overlapped state using the fixing tool, it is confirmed that the fixing tool has been removed by confirming that point. It can be easily confirmed.

  According to a third aspect of the present invention, in the fixture according to the second aspect, the shaft member extends from the shaft member so as to incline in the one end direction, and is elastic in a direction intersecting the axial direction of the shaft member. A locking piece that deforms, and the engaged member engages with the locking piece in a state in which the other end of the shaft member is inserted into the insertion hole, and the shaft member comes out of the insertion hole. It is provided with the to-be-latched piece to suppress.

If it is a fixing tool comprised in this way, engagement with a shaft member and a to-be-engaged member is carried out by the locking piece formed in the shaft member, and the to-be-latched piece formed in the to-be-engaged member. Can be realized.
According to a fourth aspect of the present invention, in the fixture according to the third aspect, at least one of the locking piece and the locked piece is the one when the shaft member is inserted into the insertion hole. A plurality of shaft members are arranged along the axial direction of the shaft member.

  If it is a fixing tool comprised in this way, the position (insertion depth to the insertion hole of a shaft member) which a latching piece and a to-be-latched piece can engage can be adjusted. In order to appropriately hold the first protruding piece and the second protruding piece in a stacked state, the thickness in the stacked state, the distance between the engaged member that sandwiches them and the overhanging portion, However, when the insertion depth of the shaft member into the insertion hole can be adjusted, the distance between the engaged member and the overhanging portion can be adjusted.

  Therefore, the thickness in the state in which the first protruding piece and the second protruding piece are overlapped may not be a specific thickness, and the first protruding piece and the second protruding piece having various thicknesses may be used. On the other hand, the superposition state can be maintained satisfactorily.

  According to a fifth aspect of the present invention, in the fixture according to the first aspect, an opening is formed in which the first protruding piece and the second protruding piece that are in the overlapped state can be inserted, and the opening A cover member provided with two snaps that are inserted into the inlets at both ends of the continuous hole when the first projecting piece and the second projecting piece in the superposed state are inserted. In the cover member, the break region is formed along the insertion direction of the first projecting piece and the second projecting piece from the peripheral edge of the opening, and the two snaps are formed on the continuous hole. The superposition state is maintained by being inserted from the inlets at both ends.

  In the fixture configured as described above, when the first projecting piece and the second projecting piece are inserted into the opening, the snap is locked to the continuous hole and the first projecting piece and the second projecting piece come out of the opening. In order to suppress this, it can be held in a superposed state.

  Furthermore, since the fracture region is formed along the insertion direction of the first projecting piece and the second projecting piece from the peripheral edge of the opening in the cover member, the cover is broken when the force is applied to the fixture and the fracture region breaks. The shape of the opening of the member is deformed, and the overlapping state cannot be maintained by the cover member. As a result, it is possible to easily confirm whether or not the fixture has been removed simply by looking at the fixture. In addition, since the cover member is damaged as described above, the cover member cannot be reused to hold the first protruding piece and the second protruding piece in an overlapped state. It is also possible to easily confirm that the fixture has been removed by confirming the above.

  The fixture according to claim 6 is the fixture according to claim 4, further comprising an extending portion extending from a position along the fracture region of the cover member toward the outside of the cover member. To do.

  In the fixture configured as described above, when a load is applied to the extending portion, a strong force is applied to the fracture region, and thus the fracture region is easily broken. That is, when the fixing tool is forcibly removed, the fracture region is more easily broken, so that it can be confirmed more reliably that the fixing tool has been removed. On the other hand, when it is necessary to remove the fixture, it is convenient because the fixture can be easily broken by applying force to the extension.

  The invention according to claim 7 is the fixture according to claim 1, which is a columnar member, and has an overhanging portion projecting to the outer peripheral side at one end thereof, and the shaft member so as to incline toward the one end. A locking member that extends from the shaft and elastically deforms in a direction intersecting with the axial direction of the pillar, a first opening into which the other end of the axial member can be inserted, and the overlapping A case member having the first projecting piece and the second opening into which the second projecting piece can be inserted, and the breaking region includes the locking piece in the shaft member and the second member.

  Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.

[Example 1]
(1) Configuration of Fixing Tool As shown in FIGS. 1 (A) and 1 (B), the fixing tool of this embodiment is composed of a resin engaged member 2 and a shaft member 4. And it is used when fixing two different articles | goods 6a and 6b. 1A and 1B show only a part of the articles 6a and 6b.

  Projecting pieces 8a and 8b, which are plate-like members, are formed on the articles 6a and 6b, respectively. Rectangular through holes 10a and 10b are formed on the main surfaces of the protruding pieces 8a and 8b. The fixing device of this embodiment is overlapped so that the through holes 10a and 10b described above are aligned to form one continuous hole, and the protruding directions of the protruding piece 8a and the protruding piece 8b are aligned in the same direction. The overlapped state (the state of the protruding piece 8a and the protruding piece 8b shown in FIG. 1A) is maintained.

  The engaged member 2 described above has a cylindrical portion 20 having a cylindrical shape with a square cross section. One of the wall surfaces constituting the cylindrical portion 20 is a plate 22 extending wider than the other surfaces. The plate 22 can be displayed by forming character information or a pattern in advance or by filling in later.

  Inside the cylindrical portion 20 is an insertion hole 24 into which the shaft member 4 can be inserted. Of the inner side surface of the cylindrical portion 20, a plurality (three in this embodiment) of locking pieces 26 are formed along the axial direction of the cylindrical portion 20 on the surface on the plate 22 side.

In addition, an opening 28 is formed in the wall surface of the cylindrical portion 20 that faces the plate 22.
The shaft member 4 includes a columnar base material 30, a plurality (five in this embodiment) of locking pieces 32 connected to the base material 30, and an overhang portion 34 that projects to the outer peripheral side of the base material 30. It consists of. The locking pieces 32 are provided so as to be arranged along the axial direction from the other end 30 a of the base material 30. The overhanging portion 34 is provided at one end 30b opposite to the other end 30a.

The locking piece 32 extends from the base material 30 so as to be inclined in the direction of the one end 30b, and is elastically deformed in a direction crossing the axial direction of the base material 30.
The overhanging portion 34 has a rectangular plate shape and is formed to be larger than the through holes 10a and 10b of the articles 6a and 6b described above, and cannot pass through the through holes 10a and 10b.

  In addition, a break region 36 formed thinner than the surroundings is provided between the region where the locking piece 32 is provided in the base material 30 and the overhanging portion 34. The fracture region 36 has a smaller tensile strength than the surrounding portion of the base material 30, and the fracture region 36 is first fractured when stress is applied to the base material 30.

(2) Usage of Fixing Tool FIGS. 2 (A) and 2 (B) show a state in which the protruding piece 8a and the protruding piece 8b are held in the above-described overlapping state using the fixing tool of this embodiment.

  A procedure for attaching the fixture will be described. First, the one end 30a side of the shaft member 4 is inserted and passed through a continuous hole formed by arranging the through holes 10a and 10b in a line. Next, the one end 30 a side of the shaft member 4 that has passed through the through holes 10 a and 10 b is inserted into the insertion hole 24 of the engaged member 2.

  When the fixing tool is attached in this manner, the locking piece 32 engages with the locked piece 26 provided inside the insertion hole 24, so that the shaft member 4 is prevented from coming out of the insertion hole 24 (shaft The member 4 and the engaged member 2 are engaged). In this way, by holding the protruding piece 8a and the protruding piece 8b between the engaged member 2 and the overhanging portion 34, the overlapping state of the protruding piece 8a and the protruding piece 8b is realized.

  In the state where the fixture is attached as described above, if the protruding piece 8a and the protruding piece 8b are to be separated, the engagement between the engaged member 2 and the shaft member 4 needs to be released. Since the piece 32 and the locked piece 26 are engaged inside the cylindrical portion 20, they cannot be easily released.

  Here, if a strong force is applied to the engaged member 2 and the shaft member 4 to forcefully remove the engaged member 2 and the shaft member 4, the fracture region 36 that is vulnerable to stress will break. As a result, the shaft member 4 can no longer be reused, and the shaft member 4 breaks, leaving traces of forcibly removing the fixing tool from the protruding pieces 8a and 8b, so that it is easy to remove the fixing tool. Can be determined.

  In addition, since a plurality of the locking pieces 32 and the locked pieces 26 are arranged along the axial direction of the shaft member 4 when the shaft member 4 is inserted into the insertion hole 24, the shaft member 4 and the engaged member 2 can be adjusted (the insertion depth of the shaft member 4 into the insertion hole 24). Therefore, the protruding piece 8a and the protruding piece 8b are not limited to those having a specific thickness, and it is possible to realize the overlapping state of the protruding pieces having various thicknesses.

  In the above-described embodiment, the configuration in which a plurality of the locking pieces 32 and the locked pieces 26 are provided is illustrated, but the same effect can be obtained even when only one of the locking pieces 32 and the locked piece 26 is provided.

  Further, as shown in FIGS. 3A and 3B, the shaft member 4 in the fixture of the present embodiment locks the locking piece 32 not on the locked piece 26 but on the edge of the through hole 10a. Thus, the overlapping state of the protruding piece 8a and the protruding piece 8b can be maintained without using the engaged member 2.

  In this state, the locking of the locking piece 32 with respect to the edge of the through hole 10a can be easily released simply by pressing the locking piece 32 toward the base material 30 with a finger or the like. That is, in the fixture of the present embodiment, by using only the shaft member 4, the protruding piece 8a and the protruding piece 8b can be temporarily fixed.

[Example 2]
(1) Structure of fixture The fixture 40 of a present Example is shown to FIG. 4 (A) and (B). The fixture 40 is made of resin and is used when two different articles 6a and 6b are fixed as in the first embodiment. Since the articles 6a and 6b have the same configuration as that of the first embodiment, the same reference numerals are used and description thereof is omitted.

The fixture 40 includes a cover member 42, a plate 44, and a connecting portion 46 that connects the cover member 42 and the plate 44.
The cover member 42 is a hollow box-shaped member, and one surface (the left side surface in FIGS. 4A and 4B) is in the above-described overlapping state of the protruding piece 8a and the protruding piece 8b. It is comprised as the opening 50 which can insert. In the present embodiment, since the entire surface is an opening in the present embodiment, no wall surface actually exists on the surface.

  A pair of snaps 48 whose tips extend toward the opening 50 are provided on the surface 42a facing the one surface described above (located on the right side in FIGS. 4A and 4B). The pair of snaps 48 are arranged at an interval at which a slight gap is generated when the protruding piece 8a and the protruding piece 8b in an overlapped state are inserted. The tip 48a of the snap 48 is formed in a bowl shape facing the direction of the opening 50.

The connecting portion 46 has an opening 46a at the center, and as a result, is formed thinner in the width direction than the surroundings. That is, the connecting portion 46 becomes a fracture region in the present invention.
(2) Use Mode of Fixing Tool FIGS. 5 (A) and 5 (B) show a state in which the protruding piece 8a and the protruding piece 8b are held in the above-described overlapping state using the fixing tool 40 of the present embodiment.

  When the protruding piece 8a and the protruding piece 8b are inserted into the opening 50 of the cover member 42, the distal end portion 48a of the snap 48 is formed at the inlets at both ends of the continuous hole formed by arranging the through holes 10a and 10b (to the through holes 10a and 10b, respectively). Is inserted and engaged. Further, since the protruding piece 8a and the protruding piece 8b are surrounded by the wall surface of the cover member 42 and the snap 48, the snap 48 is engaged in this manner, so that the above-described superposition state can be maintained.

  Here, if a strong force is applied to the fixture 40 to forcefully remove it from the articles 6a and 6b, the connecting portion 46 (rupture region) which is formed thin and weak against stress is broken. As a result, since a trace of forcibly removing the fixture 40 from the articles 6a and 6b remains, it is possible to easily determine that the fixture 40 has been removed.

[Example 3]
(1) Structure of fixing tool The fixing tool 60 of a present Example is shown to FIG. 6 (A)-(G). The fixture 60 is made of resin and is used when two different articles 6a and 6b are fixed as in the first embodiment. Since the articles 6a and 6b have the same configuration as that of the first embodiment, illustration and description thereof are omitted.

The fixture 60 includes a cover member 62 and a plate 64.
The cover member 62 is a box-shaped (cylindrical) member, and the protruding piece 8a and the protruding piece 8b in which one surface (the rear surface in FIG. 6A) is in the above-described overlapping state can be inserted. The opening 68 is configured. In the present embodiment, since the entire surface is an opening in the present embodiment, no wall surface actually exists on the surface.

  A pair of snaps 66 whose front ends extend toward the opening 68 are provided on the surface 62a facing the one surface described above (positioned at the front in FIG. 6A). The pair of snaps 66 are arranged at an interval at which a slight gap is generated when the protruding piece 8a and the protruding piece 8b in an overlapped state are inserted.

  The surfaces 62b and 62c intersecting the surface 62a of the cover member 62 are thinner than the surroundings along the insertion direction from the opening 68 of the protruding piece 8a and the protruding piece 8b (front-back direction in FIG. 6A). The fracture region 70 is formed. Further, two plate-like extending portions 72 and 74 are provided so as to extend toward the outside of the cover member 62 in such a positional relationship as to sandwich the breaking region 70 along the breaking region 70. The extending portions 72 and 74 are provided so that their main surfaces are parallel to each other.

(2) Usage of Fixing Tool In the fixing tool 60 of the present embodiment, the cover member 62 and the pair of snaps 66 are the same as the cover member 42 and the snap 48 of the second embodiment shown in FIGS. 5 (A) and 5 (B). The protruding piece 8a and the protruding piece 8b can be held in the overlapping state described above.

  Here, if a strong force is applied to the fixture 60 to forcefully remove it from the articles 6a and 6b, the rupture region 70 which is formed thin and weak against stress is broken, and the cover member 62 is broken and maintains its shape. become unable. Therefore, since the trace which forcibly removed the fixing tool 60 from the protrusion piece 8a and the protrusion piece 8b remains because the cover member 62 is damaged, it can be easily determined that the fixing tool 60 has been removed.

  On the other hand, in order to remove the fixture 60 attached to the articles 6a and 6b, it is necessary to break the break region 70 and break the cover member 62. In this case, a force is applied to the extension portions 72 and 74. Thus, the fracture region 70 can be easily broken. For example, a rod or the like is inserted into the gap between the extension part 72 and the extension part 74 and a force is applied so as to increase the distance between them, or the distance between the extension part 72 and the extension part 74 is reduced. The fracture region 70 can be easily broken by operating with a tool or the like.

  In this embodiment, the configuration in which the extending portions 72 and 74 are provided so as to sandwich the fracture region 70 is illustrated, but a configuration in which one extension portion is provided along the fracture region may be used. 7 (A) and 7 (B), one extending portion 82 may be sandwiched between two fracture regions 84. In the fixture 80, for example, the fracture region 84 can be broken by applying a stress by pinching with a finger so as to sandwich the pair of extending portions 82. 7A and 7B, the same reference numerals are used for the same configurations as those of the fixture 60.

Moreover, the structure by which only a fracture | rupture area | region is provided may be provided without providing an extension part.
[Example 4]
(1) Structure of fixture The fixture 90 of a present Example is shown to FIG. 8 (A)-(H). The fixture 90 is made of resin and is used when two different articles 6a and 6b are fixed as in the first embodiment. Since the articles 6a and 6b have the same configuration as that of the first embodiment, the same reference numerals are used and description thereof is omitted.

The fixture 90 includes a cover member 92 and a plate 94.
The cover member 92 is a cylindrical member. In one opening 96, the protruding piece 8a and the protruding piece 8b in the above-described overlapping state can be inserted. On the peripheral edge of the other opening 98, a pair of plate-like projecting portions 100a and 100b that are opposed to each other and extend along the cylindrical axial direction of the cover member 92 are provided.

  The protrusions 100 a and 100 b are connected to a pair of snaps 102 at both ends in a direction intersecting the direction extending from the opening 98. The pair of snaps 102 are disposed so as to be inserted into the cover member 92 from the opening 98. One of the snaps 102 is formed so as to be flush with the plate 94.

(2) Usage of Fixing Tool In the fixing tool 90 of the present embodiment, the cover member 92 and the pair of snaps 102 are the same as the cover member 42 and the snap 48 of the second embodiment shown in FIGS. 5 (A) and 5 (B). The protruding piece 8a and the protruding piece 8b can be held in the overlapping state described above.

  In order to remove the fixing device 90, it is necessary to release the engagement (not shown) of the snap 102 to the through holes 10a and 10b. However, the engagement portion is covered with the cover member 92, so that it can be easily moved. I can't.

  Therefore, it is necessary to operate the root portion of the snap 102 located outside the cover member 92 in the snap 102, but a very strong force is required to move the tip portion engaged by operating the root of the snap 102. Need to be added. Therefore, when a force is applied to the base of the snap 102, the snap 102 whose thickness in the width direction (the arrow direction in FIGS. 8A and 8B) is thinner than the surroundings (the plate 94 and the cover member 92) is broken. Therefore, since the trace which forcibly removed the fixing tool 90 from the protruding piece 8a and the protruding piece 8b remains due to the snap 102 being damaged, it can be easily determined that the fixing tool 90 has been removed.

  Note that the vicinity of the root of the snap 102 may be formed thinner than the surroundings. If configured in this way, the snap 102 is easily broken when a force is applied to the root in an attempt to release the engagement of the snap 102. Therefore, the trace of releasing the fastener 90 by releasing the engagement of the snap 102 can be further improved. Can be left with certainty.

As a result, the locking piece 154 is locked to the peripheral portion of the continuous hole (the peripheral portion of the through hole 10b).

  In the state where the fixture is attached as described above, the protruding piece 8a and the protruding piece 8b are surrounded by the second opening 148, and the protruding piece 8a and the protruding piece 8b are opened by the shaft member 142 to the second opening. Since it cannot be removed from 148, the superposition state is maintained.

  In order to pull out the protruding piece 8a and the protruding piece 8b from the second opening 148, it is necessary to release the locking between the locking piece 154 and the continuous hole, but the locking portion is inside the case member 144. Therefore, it cannot be released easily.

  Here, if the protruding piece 8a and the protruding piece 8b are forcibly removed from the second opening 148 or if the shaft member 142 is forcibly removed from the engaged member 140, the breaking region 156 that is vulnerable to stress is broken. . As a result, the shaft member 142 can no longer be used again, and the shaft member 142 is broken, leaving a trace of forcibly removing the fixture from the protruding piece 8a and the protruding piece 8b. Can be easily determined.

  In addition, in the fixing tool of a present Example, it is also possible to fix the protrusion piece 8a and the protrusion piece 8b only using the shaft member 142. FIG. Specifically, the protruding piece 8a and the protruding piece 8b are placed in the overlapping state described above, the shaft member 142 is passed through the continuous hole, and the locking piece 154 is fixed to the peripheral edge of the continuous hole as described above. it can.

  In this state, the locking of the locking piece 154 with respect to the edge of the through hole 10a can be easily released simply by pushing the locking piece 154 toward the base 150 with a finger or the like. That is, in the fixture of the present embodiment, by using only the shaft member 142, the protruding piece 8a and the protruding piece 8b can be temporarily fixed.

  As described above, when the case member 144 is used at the same time, the locking piece 154 cannot be operated from the outside, and the second opening 148 can prevent the protruding piece 8a and the protruding piece 8b from being displaced. The superposition state can be held more firmly.
