Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a retainer. That is, the present invention relates to a retainer that fixes an attachment member to a member to be supported in an overlapping manner through openings provided in both members.

“Prior Art” As described above, as means for fixing the mounting member such as the mounting member over the member to be supported such as the frame, generally, in addition to bolts and nuts, clips such as anchor clips and rivets such as plastic rivets have been generally used. , Other retainers are used.

Then, after stacking the mounting member on the member to be supported and also stacking both openings, such a retainer is inserted between the openings,
For example, the head and the like, which are located outside the opening, and the claw and the like are locked from above and below so that they cannot be extracted and are fixed.

"Problems to be solved by the invention" By the way, the following problems have been pointed out in such a conventional retainer.

First, the plate thickness of the attachment member and the member to be supported is required to be strictly constant. Secondly, it is also required that the size and position of the openings of the mounting member and the member to be supported are exactly the same. The conventional retainer cannot be used unless such conditions are met, that is, the mounting member cannot be fixed to the support target member, and its use is limited, which is a problem.

Such a point has been pointed out in the conventional example.

The present invention has been made in view of the above circumstances in order to solve the problems of the above-described conventional example, and in use, a flange member and a lower case that is expanded and deformed by a reaction of a foaming agent, etc. A retainer that can be used regardless of the plate thickness of the mounting member and the support target member, the opening, etc., by locking the support target member from the outside of the opening, sandwiching it, and fixing it The purpose is to propose.

"Means for Solving the Problem" The technical means of the present invention for achieving this object are as follows.

This retainer is for fixing the mounting member to the support target member in an overlapping manner through openings provided in both members. And first, it has the following upper case, lower case, and holding member.

The upper case has an upper chamber formed therein, a foaming agent is stored therein, a flange portion is laterally provided in the middle, and a pressing piece is formed at the tip of the bottom portion.

The lower case has a lower chamber formed therein and a curing agent is stored therein, and an upper surface of the lower chamber is opened and closed by a lid body, and a flange portion is laterally provided on an upper side, and at least a side portion is made of an elastic material. Made of.

The holding member is made of an elastic material that positions and holds the flange portion of the upper case and the flange portion of the lower case with a space therebetween.

The bottom of the upper case and the lid of the lower case are normally opposed to each other with a gap, and the lid is provided with a blade that can cut the bottom when the bottom is pressed. Further, a door portion is formed on the lid body at a portion facing the pressing piece on the bottom portion.

The door is normally closed, and when the pressing piece is pressed against the door, the closed end of the door is pushed open to rotate and open.

"Operation" Since the present invention comprises such means, it operates as follows.

When using the retainer, first, the mounting member is overlaid on the member to be supported and the openings of both members are overlaid. Then, the lower case of the retainer is inserted through the opening, and its flange portion is held in contact with the mounting member.

Then, when the top portion of the upper case is pressed, the holding member is elastically deformed and compressed through the flange portion, and the upper case is pushed and descends. Then, the bottom of the upper case is pressed against the blade of the lid of the lower case to be cut and opened, and the pressing piece of the bottom is pressed against the door of the lid and pushes the closed end of the lid to rotate the door. Then it is released.

Then, the foaming agent in the upper chamber of the upper case flows down into the lower chamber of the lower case through the cut opening in the bottom of the upper case and the open door of the lid. Since the foaming agent and the curing agent that have flowed down due to the reaction are mixed and react to foam and expand and harden, the lower chamber is spread outwardly,
The side portion of the lower case expands densely inside the opening and expands and deforms along the support target member outside the opening.

At the same time, by releasing the pressure on the top of the upper case, the elastic deformation of the holding member is released and it expands to return to the normal state.The upper case also rises and the pressure contact between its bottom and the lid is released to return to the normal state. After returning, the door of the lid is also closed.

Now, the attachment member and the support target member are locked and sandwiched from the outside of the opening by the flange portion and the lower case that is expanded and deformed as described above. As a result, the retainer cannot be pulled out, the mounting member is fixed to the support target member, and this state is maintained after the fact.

Now, here, the mounting member and the member to be supported are slightly different in the plate thickness and the size and position of the opening,
In this way, the two are fixed by the expansion of the lower case inside the opening and the expansion and deformation outside the opening, so that these differences are surely complemented. That is, in this retainer, it is not required that the mounting member and the support target member have strictly constant plate thicknesses and exactly the same size and position of the openings.

[Embodiment] The present invention will be described in detail below based on the embodiment shown in the drawings.

The drawing is an enlarged view showing an embodiment of the present invention. And the first
The drawing is a front sectional view thereof, and FIG. 2 is a schematic view of the appearance in use.

First, the configuration and the like will be described in the order of the outline of the retainer and the lid and the like.

The outline of the retainer is as follows.

In this retainer 1, a plate-shaped mounting member 2 such as a mounting component is superposed on a plate-shaped supporting target member 3 such as a frame, for example, through circular openings 4 and 5 having substantially the same size and provided on both members. It is something that is fixed. And next upper case 6, lower case
7, The holding member 8 is provided.

First, the upper case 6 has an upper chamber 9 formed therein so that the foaming agent A is fully filled and stored therein, and a flange portion 10 is provided in the middle.
And a pressing piece 12 is formed at the tip of the bottom portion 11.

That is, the illustrated upper case 6 has a cylindrical shape in which an upper part is formed with a large diameter and a lower part is formed with a small diameter, and is normally hermetically sealed, and an internal space serves as an upper chamber 9 in which a foaming agent A is stored.
It is made of elastic material such as rubber or resin. A flange portion 10 is laterally projected from the middle between the upper portion and the lower portion, and the diameter of the flange portion 10 is much larger than the openings 4 and 5 of the mounting member 2 and the support target member 3. . In addition, the bottom portion 11 at the lower portion is inclined, and the tip, which is the lowermost end, is the pressing piece 12.
Is formed.

The lower case 7 has a lower chamber 13 formed therein and has a hardener B.
Is fully filled and stored, the upper surface of the lower chamber 13 is opened and closed by a lid body 14, a flange portion 15 is provided on the upper side, and at least the side portion 16 is made of an elastic material.

That is, the lower case 7 shown in the drawing is made of rubber, which has a bottomed cylindrical shape with an open upper surface and whose inner space is the lower chamber 13.
It is made of elastic material such as resin. The outer diameter of the lower case 7 is
The diameter is slightly smaller than the openings 4 and 5 of the mounting member 2 and the support target member 3, and is much larger than the lower portion of the upper case 6. A flange portion 15 is laterally projected from the upper end of the lower case 7, and the diameter of the flange portion 15 is much larger than the diameter of the openings 4 and 5 of the lower case 7 and the mounting member 2 and the support target member 3, for example, the upper portion. It has the same diameter as the flange portion 10 of the case 6. The open upper surfaces of the lower case 7 and the lower chamber 13 are closed by a lid 14 having a concave shape.

The holding member 8 is made of an elastic material that holds and holds the flange portion 10 of the upper case 6 and the flange portion 15 of the lower case 7 from the outside with a gap therebetween. That is, the illustrated holding member 8 is formed of a substantially ring-shaped rubber band that holds the flange portion 10 and the flange portion 15 at an interval vertically and has an upper end protruding above the flange portion 10 and a lower end thereof. It protrudes below 15.

The outline of the retainer 1 is as follows.

Next, the lid 14 and the like will be described.

The small-diameter lower part of the upper case 6 is loosely fitted into the concave lid 14 from above, and the bottom 11 of the upper case 6 and the central bottom of the lid 14 of the lower case 7 are normally spaced apart. Then they are facing each other. On the central bottom portion of the lid body 14, a blade portion 17 is erected which can cut the bottom portion 11 of the upper case 6 when the bottom portion 11 is pressed. Then, a groove portion 18 that is cut in and thinned is formed vertically in the bottom portion 11 that has a slight interval and corresponds to this blade portion 17, and as will be described later, a cutting opening is easily made by pressure contact with the blade portion 17. It is supposed to do.

Further, at a portion of the bottom portion 11 of the lid body 14 facing the pressing piece 12, a door portion is provided.
19 are formed. This door portion 19 is normally closed, and when the pressing piece 12 is pressed in use as described below,
The grooved closed end 20 that has been cut and thinned is cut and pushed open, so that the door portion 19 can be rotated and opened from the state shown by the solid line in FIG. 1 as shown by the broken line. There is.
Reference numeral 21 is the center end of the rotation of the door portion 19, and has a groove shape that is cut and thinned.

Reference numeral 22 in the drawing denotes a plate, and the plate 22 is made of a hard material having a disc shape with an opening at the center. The plate 22 is arranged on the flange portion 15 of the lower case 7,
The inside is located between the flange 15 and the upper edge of the lid 14, and the outside is located between the flange 15 and the holding upper surface of the holding member 8.

The above is the description of the configuration and the like.

The operation and the like will be described below.

When using the retainer 1, first, as shown in FIG.
The mounting member 2 is overlapped on the support target member 3 and the openings of both
Stack 4,5. Then, open the lower case 7 of the retainer 1.
It is pushed from 4 and 5 to the lower side of the support target member 3 and inserted, and the flange portion 15 is abutted and held on the mounting member 2 via the lower end of the holding member 8 in the illustrated example.

Then, when the top portion of the upper case 6 is pressed downward from above by a finger or the like, the holding member 8 is elastically deformed via the flange portion 10 and vertically compressed, and the upper case 6 is pushed and descends. The groove portion 18 provided in the bottom portion 11 at the lower portion of the upper case 6 is pressed against the blade portion 17 of the lid body 14 of the lower case 7 to be cut and opened, and the pressing piece 12 of the bottom portion 11 is opened.
The door portion 19 is pressed against the door portion 19 and its closed end 20 is cut and pushed open, and the door portion 19 rotates downward about the rotation center end 21 from the state shown by the solid line in FIG. It will be released.

Then, the foaming agent A in the upper chamber 9 of the upper case 6 enters the lower chamber 13 of the lower case 7 through the cut opening of the groove 18 of the bottom 11 of the upper case 6 and the open door 19 of the lid 14. It moves down into the curing agent B. Then, the foaming agent A and the curing agent B, all of which have flowed down, are mixed and react to foam and cure while increasing in volume, that is, while expanding and curing, the lower chamber 13 is expanded outward. As a result, the side portion 16 of the lower case 7 spreads densely inside the openings 4 and 5 of the mounting member 2 and the support target member 3, and expands and deforms laterally along the support target member 3 below the openings 4 and 5. To do.

At the same time, by releasing the pressure on the top of the upper case 6, the holding member 8 is released from elastic deformation and extends to return to the original normal state. Then, the upper case 6 also rises and returns to the normal state, and the pressing piece 12, the groove portion 18 and the like of the bottom portion 11 and the lid body 14 are
The pressure contact with the door portion 19, the blade portion 17 and the like is released to return to the normal state, and the door portion 19 is closed. Therefore, as described above, the lower chamber 13
It is prevented that the foaming agent A or the like which reacts inside and is being foam-cured returns to the upper chamber 9 or the like from the lower chamber 13 again.

Now, in the illustrated example, the mounting member 2 and the support target member 3 include the flange portion 15 in which the plate 22 and the lower end of the holding member 8 are interposed above and below, and the lower case 7 in which the inside is hardened by expansion and deformation as described above. Thus, they are locked and pinched from above and below the openings 4, 5. Therefore, as shown in FIG. 2, the retainer 1 cannot be pulled out, and the mounting member 2 is fixed to the support target member 3, and this state is maintained after the fact.

Now, even if the mounting member 2 and the support target member 3 are slightly different in plate thickness and sizes and positions of the openings 4 and 5, the spread of the lower case 7 in the openings 4 and 5 is as described above. Since the two are fixed by expansion deformation and the like outside the openings 4 and 5, some differences between them are surely complemented. That is, in the retainer 1, the mounting member 2 and the support target member 3 are not required to have a strictly constant plate thickness and the openings 4 and 5 to have the same size and position.

The above is the description of the operation and the like.

In the retainer 1 of the illustrated embodiment, first, the upper case 6 and the lower case 7 are prepared respectively, and the post-holding member 8 is provided.
It is manufactured by attaching between the flange parts 10 and 15 of both. Therefore, this retainer 1 has an advantage that it is easy to manufacture.

The cross-sectional shape of the lower part of the upper chamber 9, the cross-sectional shape of the concave portion of the lid 14 and the like are not limited to those in the embodiment, and may be rectangular in cross section, for example.

[Advantage of Invention] As described above, the retainer according to the present invention locks the attachment member and the support target member from the outside with the flange portion and the lower case that is expanded and deformed by the reaction of the foaming agent etc. The following effects are exhibited by sandwiching them with each other and fixing them so that they cannot be extracted.

That is, first, the attachment member and the support target member are not required to have a strictly constant plate thickness, and can be used even if they are slightly different. Secondly, the mounting member and the member to be supported are not required to have exactly the same size and position of their openings, and can be used even if they are slightly different. Therefore, this retainer is simple and easy to use and has a wide range of applications. As described above, the problems existing in the conventional example of this kind are eliminated, and the effect of the present invention is remarkable.
