Description

  The present invention relates to a connector used for connecting panels such as plastic cardboard.

  Conventionally, the panel is connected to the connector main body corresponding to the various plate thicknesses, various materials, and different members applied by the present applicant, and the connected connector main body is connected to be used for temporary partitioning or the like. There are plate-like connectors such as panels. (For example, see Patent Document 1)

  In addition, a fitting convex shape of the connecting member 7 is formed in the fitting concave portion 8 of the post 5 by inserting the edge of the partition plate 6 into the plate outer fitting concave portion 14 c of the attachment portion 14 formed in the connecting member 7. There is a partition showing an embodiment in which the portion 15 is fitted and assembled as a partition. (For example, see Patent Document 2)

  Further, the upper portion of the upper screen 5 is fitted to the fitting portion 8a of the connector 8, and the upper screen 5 is prevented from being twisted and the elasticity of the fitting portion 8a is appropriately utilized. In the embodiment, a plurality of ridges 18 (or grooves are formed) are formed on the inner surface of the fitting groove 17 so that the corners of the upper screen 5 are tightly fitted without looseness. There is a fixture with an upper screen and a connector used for this. (For example, see Patent Document 3)

  In addition, as a general use example, small enclosures and toy houses that children can assemble and play on panels such as plastic cardboard, which children often play with cardboard boxes, are provided to the general market.

  The connector of the plate-like body 18 such as the panel of Patent Document 1 filed by the present applicant corresponds to the connector body 2 being deformed so as to correspond to the thickness of the plate-like body 18 to be connected. Although the strength is maintained by setting the connector body 2 to be slightly larger according to the corresponding deformation amount, when using a thin or weak plate-like body 18 that is greatly different from the corresponding size, For example, when plastic corrugated cardboard (other paper corrugated cardboard, color corrugated cardboard, polystyrene board with a colored paper liner attached to the middle board of foamed polystyrene) is used, the connector body 2 is too large for it, and it corresponds to the design balance. The strength of the plate-like body 18 was not balanced and did not fit.

  Further, the material that is relatively weak to bending of the thin plate-like body 18 is weak at the connecting portion between the plate-like body 18 and the connector main body 2 and easily bends. Since commonly known adhesive layers 8 and 8 such as a double-sided tape are used for connecting and bonding the plate-like body 18 to the bodies 3 and 3, the double-sided tape is provided on the adhesive supports 3 and 3. However, there is room for improvement in terms of manufacturing, and the labor of peeling the release paper when the plate-like body 18 is connected and bonded, and the release paper becomes waste and wasteful.

  Therefore, it can be used for a plate-like body 18 such as a relatively thin and weak panel, corresponds to the design balance and size of the connector and the plate-like body 18, and can be easily and stably subjected to a certain thickness difference. It has been improved so that it can be fitted and fixed with adhesive, and can be manufactured more easily, making the connection work more efficient and considering the environment.

Further, in the partition of Patent Document 2, the width of the externally fitted recess 14c of the connecting member 7 is fixed, and the thickness of the partition 6 fitted to the externally fitted recess 14c is dedicated to a predetermined thickness. Thus, when the plate thickness is somewhat thin, the partition plate 6 rattles, and there is a problem that a general-purpose or combination panel cannot be used because it is unstable and does not correspond to the difference in plate thickness.

  Furthermore, the fixture with an upper screen of patent document 3, and the connection tool used for this are the fitting connection 8a of the connection tool 8 to the upper corner part of the upper screen 5, and when the fitting connection is performed, In order to prevent twisting, a plurality of protrusions 18 (or grooves) are formed on the inner surface of the fitting groove 17 to prevent twisting. On the contrary, if a pulling force is applied, the protrusion 18 Projecting at right angles to the inner surface of the fitting groove 17, the contact surface of the ridge 18 and the contact surface of the upper screen 5 are small, and the contact resistance is also small. As a result, the coupling force is weakened, and therefore, there has been a problem of a coupling tool that does not rattle during fitting and does not easily come off.

  Conventionally, small enclosures and toy houses, etc., have been provided to fold objects manufactured in a predetermined shape, and connected to a panel having a connecting body with the connecting body and assembled into a predetermined shape. It was desired that the panel bends at the corner of the joint between the panel and the connecting body, and the pain was severe, and the panel was elastically supported to a certain degree and was not easily bent.

In order to effectively achieve the above-mentioned problems, the present invention provides a connector body having a substantially U-shaped cross section that is continuous in the longitudinal direction, and includes an inner side that is partitioned into a substantially U-shaped cross section. An adhesive support portion that is formed as a fitting portion and has an adhesive material that is substantially plate-like and can be elastically deformed elastically is formed on both surfaces facing each other on the inner surface of the fitting portion toward the back of the connector main body. A concave portion corresponding to the adhesive support portion is formed so as to project obliquely and the adhesive support portion can protrude and retract from an opposing inner surface of the fitting portion, and the substantially U-shaped of the connector main body is formed. By providing a connection locking portion that protrudes from the vicinity of the substantially central portion of the outer curved surface portion,
By inserting the panel edge into the fitting part, the adhesive support piece is held in correspondence with a slight difference in plate thickness, and the adhesive support piece is deformed corresponding to the panel thickness within the fitting part width. It acts to hold the panel and the like, and is supported in a stretched manner against the force in the pulling direction, and is further connected by the connection locking portion to form a partition or the like.

According to the present invention, an effective effect can be obtained by each of the above-described means. In particular, the first solving means is a connector body having a substantially U-shaped cross section that is continuous in the longitudinal direction. An adhesive support portion which is formed in a substantially U-shaped inner side as a fitting portion, and has a substantially plate-like and soft elastically deformable adhesive material on both surfaces facing each other on the inner surface of the fitting portion. the PSA supporting unit as well as protruding obliquely toward the back of the connector body, so as to be retractable from the opposing inner surfaces of the fitting portion, a recess corresponding to the adhesive support, also Since there is provided a connection locking portion that protrudes from the vicinity of the substantially central portion of the substantially U-shaped outer curved surface portion of the connector main body,
Simply by inserting the panel edge into the mating part, the adhesive support pieces formed on both faces of the mating part are adhesively supported and can be fitted and connected, so the panel can be connected simply by insertion. In addition, since the adhesive support piece supports the adhesive and supports it in a pulling manner against the force in the pulling direction in response to slight differences in the plate thickness, even a panel thinner than the fitting part can be easily fitted. Can connect.

  In addition, regarding the strength of the connection between the connector main body and the panel, the panel near the insertion port of the connector main body tends to bend with the insertion port serving as a fulcrum, particularly if it is a thin panel. Since the adhesive support piece is at the midpoint between the opposing faces of the joint, there is a gap between the portion serving as the fulcrum of the insertion port and the panel, and it is flexibly supported, so that bending is eased and bending is prevented, It is particularly durable and can be used for a long time.

  In addition, the adhesive support piece is a soft, elastically deformable adhesive that protrudes diagonally in the back, making it easy to connect by simply inserting the panel edge into the fitting part. It is not necessary to provide a double-sided tape like this, making it easy to manufacture and reducing costs, making it possible to improve the efficiency of the connection work without peeling off the tape release paper, and considering the environment because the release paper is not generated .

In addition , since the adhesive support piece is deformed so as to be buried in the recess in accordance with the panel thickness within the range of the fitting part width, the panel thickness can be selected within the predetermined range and the fitting part width can be selected. Even thinner panels do not peel off and are securely adhered without disconnecting the mating connection.

Furthermore, since the adhesive support of the fitting part is an intermediate support that supports the thin panel in the vicinity of the opposite part of the fitting part, if the panel is thin , the width of the left and right gaps is wide and flexible. Since it is supported by adhesion, bending is minimized, and it is supported in a stretched manner against the force in the pulling direction, so that even a thin panel does not come off easily.

In addition, the adhesive support piece of the connector main body flexibly supports the panel so that the panel does not bend easily and is resistant to pulling, so the panel is connected and assembled by the connector main body into a small enclosure or toy house. When used, it is elastically deformed somewhat flexibly even under heavy use, so it can withstand severe play of children and can be used stably.
Therefore, the present invention has a remarkable effect in practice.

  When connecting and connecting the panels with a connector body corresponding to a relatively thin panel, the panel can be easily connected by simply inserting it into the fitting part, and the panel can be easily bent without bending. In addition, even if the panel thickness is different within a certain range, it can be easily adhered without being peeled off, and can respond to the panel thickness. A connection that never happened.

  An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a connector, which includes a connector body 2 having a substantially U-shaped cross section that is continuous in the longitudinal direction, and the connector body 2. The connection latching | locking part 3 which protrudes from the outer curved surface part of the substantially U-shaped approximate center part vicinity is formed, and this connection latching | locking part 3 follows the connector main body 2 of the connector 1 continuous in the said longitudinal direction. A locking head 3a is formed at the distal end portion to be connected and locked.

  Then, an inner surface having a substantially U-shaped cross section defined on the inner side of the connector main body 2 is formed as a fitting portion 4, and both inner surfaces facing each other on the inner surface of the fitting portion 4 are substantially plate-like and soft. The adhesive support pieces 5, 5,... Made of elastic material that can be elastically deformed are protruded obliquely in the back direction, and two rows are formed between the front end side and the back end side of each surface, respectively, and the cross section is substantially C-shaped. It is formed to face.

  Further, when the adhesive support pieces 5, 5,... Of the fitting portion 4 swing, the adhesive support pieces 5, 5,. The adhesive support pieces 5, 5,... Are slidably inserted into the recessed portions 6, 6, and so on, and 8 in the drawing is a connector body 2. These are buffering hole portions 8 for buffering received from various directions.

  The connector main body 2 is made of a thermoplastic elastomer, and the adhesive support pieces 5, 5,... Are made of two-color extrusion molding using two kinds of materials using an adhesive thermoplastic elastomer. 1 is integrally formed.

2 is substantially the same as the connector 1 described above and is different from the above-described connector 1 in that the adhesive support pieces 5, 5,... And the recessed portions 6, 6,. .. Are formed to be the optimum size for connecting and using a panel 7 having a thickness relatively thinner than the inner surface width of the fitting portion 4.

  Thus, in using the connector 1, as shown in FIGS. 3 and 4, the edge portion of the panel 7 is inserted and fitted into the fitting portion 4 of the connector 1, and the adhesive support pieces 5, 5,. Adhesion fitting and holding are performed, and the insertion fitting is performed by inserting and fitting the end edge of the panel 7 from the substantially C-shaped spread portion of the adhesive support pieces 5, 5,. The adhesive support pieces 5, 5, etc. having a substantially C-shape are supported in a stretched manner with respect to the pulling-out direction after adhesion, so that they are not easily detached and the other edge of the panel 7 is also the same Are formed as a connecting panel 9 by fitting and holding connectors 1 and 1 at both ends of the panel 7.

  Further, when the thickness of the panel 7 to be inserted and fitted is substantially the same width as the opposed inner surface width of the fitting portion 4, as shown in FIG. 3, the adhesive support pieces 5, 5,. The panel 7 is adhesively held by being pushed up to a state where it is buried in the recessed portions 6, 6.

  On the other hand, when the plate thickness of the panel 7 is thinner than the above-mentioned width, the adhesive support pieces 5, 5,... Are buried in the recessed portions 6, 6,. In the state where the adhesive support pieces 5, 5,... Protrude substantially from the partitioned inner surface of the fitting portion 4 in a substantially square shape, the panel 7 is held in the vicinity of the middle portion of the fitting portion 4. Since the thin panel 7 which is easy to bend because the adhesive support is at the middle point, the vacant width from both inner surfaces is widened by the thin amount, and it is flexibly supported by the adhesive, and the bending is kept to a minimum. The panel 7 is adhesively held.

  Further, as shown in FIG. 5, the connector 1a is adhered and held to the edge of the panel 7 by a pair of adhesive support pieces 5 and 5 in substantially the same manner as the connector 1 of the embodiment of FIG. Similarly, the edge portions are fitted and connected to both end edges of the panel 7 to form the connecting panel 9a.

  As shown in FIG. 6, when the thickness of the panel 7 is thin, it is substantially the same as the embodiment of FIG. 4 described above, and in the difference, the pair of adhesive support pieces 5 and 5 are substantially stretched in a substantially C shape. By holding the panel 7 in the intermediate state in an intermediate state, the panel 7 is adhesively held so as to be swingable within a predetermined range as shown by the arrow in FIG. At this time, the panel 7 is connected to the connector 1a so that it is not easily bent.

  Therefore, when the connecting panel 9 or the connecting panel 9a formed as described above is connected and used as a partition or the like, it is connected by the connecting columns 10 and 11 shown in FIGS. 7 and 9 to form a partition into a predetermined shape. use.
