  As shown in FIG. 1, the frame 2 includes a panel unit 10 that sandwiches exhibits such as posters, a frame 20 disposed on the periphery of the panel unit 10, and a suction cup 30 for attaching the frame 20 to a tile or window glass. .

  Although illustration is omitted, the panel unit 10 includes two window members made of a transparent material and a support plate sandwiched between the two window members. Thereby, the panel part 10 can accommodate simultaneously the different posting on the both surfaces side of a support plate. In addition, the panel part provided with one window member and support plate which consist of transparent materials may be sufficient.

  As shown in FIG. 2, the frame 20 is formed in a rectangular shape, and forms an upper straight member 20T forming an upper straight portion, a lower member 20U forming a lower straight portion, and a right straight portion. It includes a right side member 20R, a left side member 20L that forms a left straight portion, and four joints 20J that connect the side members to each other.

  As shown in FIG. 3, the left side member 20 </ b> L is formed in a square tube shape. A slit S into which the panel unit 10 can be inserted is formed on the surface of the left side member 20L that is the inner peripheral surface of the frame. Accordingly, the left side member 20L has a U-shaped cross section. An opening X is formed in a surface GM that is an outer peripheral surface of the frame in the left side member 20L. Since the upper side member 20T, the lower side member 20U, and the right side member 20R are similar in structure to the left side member 20L, their details are omitted.

  The joint 20J is formed in an L shape, and connects the left side connecting member 20JL connected to the left side member 20L, the lower side connecting member 20JU connected to the lower side member 20U, the left side connecting member 20JL, and the lower side connecting member 20JU. The connecting portion 20JC and a screw 20JK for connecting the connecting portion 20JC and the suction cup 30 are provided.

  The left side connecting member 20JL is formed in a square cylinder shape, and is slidable in the longitudinal direction from the open end of the left side member 20L. Furthermore, the left side connecting member 20JL has an engagement piece KH that can be deformed between a state protruding from the side surface of the square tube (protruding state) and a state retracting from the protruding state (retracting state). The engagement piece KH is biased to the protruding state. For this reason, when the left side connecting member 20JL is slid in the longitudinal direction from the opening end of the left side member 20L, the engagement piece KH is engaged with the opening X, and the sliding movement is restricted. Thus, the left side member 20L is connected to the left side connection member 20JL. In this state, it is preferable that a slit into which the panel unit 10 can be inserted is formed in a portion of the left side connecting member 20JL that overlaps the slit S of the left side member 20L.

  Further, the left side member 20 can be slid by pushing the engagement piece KH protruding from the opening X into the retracted state. Thereby, the left side member 20L can be removed from the left side connecting member 20JL.

  Since the lower side connecting member 20JU has the same structure as the left side connecting member 20JL, its details are omitted.

  Further, the left side member 20L is slidable with respect to the lower side connecting member 20JU, and the opening X of the left side member 20L and the engaging piece KH of the lower side connecting member 20JU can be engaged. That is, the left side connecting member 20JL and the lower side connecting member 20JU are compatible with the left side member 20L and the lower side member 20U, respectively.

  The connecting portion 20JC is formed in a box shape, and a screw hole NX is formed in the ridge line L. The screw hole NX extends in a direction that bisects the angle formed by the direction in which the left side connecting member 20JL extends (V direction in the drawing) and the direction in which the lower side connecting member 20JU extends (H direction in the drawing). . The screw 20JK can be screwed into the screw hole NX.

  In addition, although one of the four joints 20J constituting the frame 20 has been described, the remaining three joints have the same structure, and thus detailed description thereof is omitted.

  The suction cup 30 includes a disk-shaped suction portion 30A that is sucked against an adherend member such as a window glass, and a protrusion 30B that protrudes from the central portion of the suction portion 30A. The protrusion 30B is formed with a hole 30BX through which the screw 20JK can pass.

  Next, a method for using the joint 20J will be described.

  As shown in FIGS. 2 to 3, when the left side connecting member 20 </ b> JL is slid in the longitudinal direction from the opening end of the left side member 20 </ b> L, the engagement piece KH is engaged with the opening X. Since the engagement piece KH is biased to the protruding state, the sliding movement of the left side member 20L with respect to the left side connection member 20JL is restricted. Similarly, the lower side connecting member 20JU is connected to the lower side member 20U. Thereby, the left side member 20L and the lower side member 20U are connected via the joint 20J. Similarly, when the remaining three joints 20J are connected to each other, a rectangular frame 20 is completed.

  Next, a procedure for connecting the joint 20J and the suction cup 30 will be described.

  After inserting the screw 20JK into the hole 30BX of the suction cup 30, the screw 20JK is temporarily tightened into the screw hole NX of the joint 20J. Thereby, the suction cup 30 becomes rotatable around the screw 20JK. Similarly, the other three joints 20J are temporarily tightened.

  In a state where the suction cup 30 is temporarily fixed to the joint 20J, the screw 20JK extends so as to protrude toward the outside of the frame 20. For this reason, the direction of the four suction cups 30 can be easily switched to which of the two sides of the panel is directed. In the above embodiment, the screw 20JK serving as the rotation axis of the suction cup 30 is arranged so as to extend in a direction that bisects the angle between the direction H and the direction V. Not limited. The direction of the screw 20JK serving as the rotation axis of the suction cup 30 may be a direction orthogonal to the normal line of the plane formed by the direction H and the direction V.

  Here, when the screw 20JK is further tightened, the rotation of the suction cup 30 is restricted. Thus, the suction cup 30 is fixed to the joint 20J. Such a screw 20JK functions as a suction cup connecting portion that connects the joint 20J and the suction cup 30.

  In addition, the amount of tightening of the screw 20JK enables switching between a state in which the suction cup 30 is rotatable and a state in which the rotation is restricted. Accordingly, the screw 20JK also functions as a switching structure related to the rotation of the suction cup 30.

  Furthermore, since the sucker connecting portion for connecting the joint 20J and the sucker 30 only needs the screw 20JK and the screw hole NX, the structure becomes very simple compared to the frame as in Patent Documents 1 and 2. For this reason, it is possible to suppress the manufacturing cost, and it is difficult to cause a malfunction due to the manufacturing quality and damage during the mounting operation.

  The left side connecting member 20JL and the lower side connecting member 20JU are compatible with the left side member 20L and the lower side member 20U, respectively. That is, the joint 20J is compatible with side members having different lengths. For this reason, frames of various sizes can be provided at low cost. Such a joint 20 </ b> J can be used for any corner portion of the frame 20. Furthermore, each side member can be made common in upper, lower, left and right except for the length. Accordingly, the assembly parts of the frame 20 such as the joint 20J and the side members can be shared, and the types of component parts can be suppressed.

  In the said embodiment, although the suction cup 30 was attached to four corner | angular parts of the frame 20, this invention is not limited to this. The screw hole NX extends in a direction that bisects the angle formed by the direction in which the left side connecting member 20JL extends (V direction in the drawing) and the direction in which the lower side connecting member 20JU extends (H direction in the drawing). Therefore, the screw 20JK screwed into the screw hole NX protrudes from the frame 20 in an orientation that bisects the angle formed by the A direction and the B direction. For this reason, as shown in FIGS. 4 to 5, the suction cups 30 can be attached to one or two corners of the square frame 20. Thereby, the frame 20 can be fixed to a window glass or the like in a posture in which each side member is inclined with respect to the horizontal direction.

  In FIG. 5, the suction cups 30 are attached to the two corner portions facing each other in the square frame 20, but the present invention is not limited to this, and the suction cups 30 may be attached to two adjacent corner portions.

  In the above-described embodiment, the screw 20JK screwed into the screw hole NX is functioned as the outer protrusion, but the present invention is not limited to this. As shown in FIG. 6, you may provide the protrusion 20JT which protrudes from the ridgeline L of the coupling 20J. The protruding piece 20JT extends in a direction that bisects the angle formed by the direction in which the left side connecting member 20JL extends (L direction in the drawing) and the direction in which the lower side connecting member 20JU extends (U direction in the drawing). . A screw hole 20JX provided in the projecting piece 20JT is formed. When the suction cup 30 is temporarily tightened into the screw hole 20JX using the screw 20JK, the suction cup 30 is rotatable about the screw 20JK. And the suction cup 30 will be in the state by which rotation was controlled by this fastening, and will be fixed to the coupling 20J.

  In the above embodiment, the joint 20J in which the directions of the two side connecting members are 90 °, such as the left side connecting member 20JL and the lower side connecting member 20JU, is used, but the present invention is not limited to this. As shown in FIG. 7, the joint 60 includes two side connecting members 61 and 62 and a connecting portion 63 that connects them in the same straight line. The connecting portion 63 is formed in a box shape, and is formed with a screw hole NX. The screw hole NX extends in a direction orthogonal to the direction in which the side connecting members 61 and 62 extend (H direction in the drawing). The screw 20JK can be screwed into the screw hole NX. This joint 60 may be used to connect and extend short side members when making a long frame, and a suction cup 30 is added in the middle of the side to increase the holding power of the entire frame. You may use for the purpose. In addition, although illustration is abbreviate | omitted, the T-shaped coupling | joint which has three edge | side connection members may be sufficient.

  In the above embodiment, the screw 20JK and the screw hole NX are used as the suction cup connecting portion, but the present invention is not limited to this. For example, the suction cup connecting portion may be provided with a hole formed in the connecting portion 20JC, a shaft portion that can be inserted into the hole, and a retaining structure provided in the shaft portion. An example of such a suction cup connecting portion is a fastener pin.

  In the above embodiment, the screw 20JK is used to connect the joint and the suction cup, but the present invention is not limited to this. A form using an engagement member instead of the screw 20JK is shown below.

  As shown in FIG. 8, the engaging member includes a plate-like main body 81, and the joint 20 </ b> J can be hung on the suction cup 30.

  The joint 20J includes a connecting member 20JL and a connecting member 20JR that can be connected to each side member (see FIG. 3) of the frame 20, and a connecting portion 20JC that connects the connecting member 20JL and the connecting member 20JR. As shown in FIG. 9B, the connecting portion 20JC has a first side surface 20ML and a second side surface 20MR that form the outside of the frame 20. A first opening 20XL is formed in the first side surface 20ML, and a second opening 20XR is formed in the second side surface 20MR. The first opening 20XL and the second opening 20XR communicate with each other through the communication hole 20XX. The joint 20J has an engaging portion 20JZ. The engaging portion 20JZ is a portion surrounded by the first opening 20XL, the second opening 20XR, and the communication hole 20XX.

  Returning to FIG. 8A, the suction cup 30 includes a suction portion 30A and a columnar protrusion 30B. Note that an engagement groove 30BM may be provided on the peripheral surface of the protrusion 30B (see FIG. 8B).

  As shown in FIG. 9A, the main body 81 is formed with an insertion hole 81X and a slit 81S. The insertion hole 81X is one into which the protrusion 30B of the suction cup 30 can be inserted, and its shape is circular. The slit 81S extends from the insertion hole 81X to the outside of the main body 81.

  The material for forming the main body 81 is elastic, and examples thereof include plastic (polycarbonate, etc.) and metal (stainless steel, etc.).

  The main body 81 is formed in a C shape. The shape of the main body 81 is not limited to a C shape, and may be a combination of curved portions formed in a curved shape, or a combination of curved portions and linear portions formed in a linear shape. The width of the curved portion or the straight portion may be set as appropriate according to the purpose, but in order to facilitate the modification to the thickness method (details will be described later), the thickness of the curved portion or the straight portion is It is better to be thinner than their width.

  The hole forming portion 84 is a part of the main body 81 and forms the insertion hole 81X. The hole forming portion 84 includes a suction cup engaging portion 84A that engages with the protruding portion 30B when the protruding portion 30B of the suction cup 30 is inserted into the insertion hole 81X (see FIG. 8C), and an engaging portion of the joint 20J. And a joint engaging portion 84B that can be engaged with 20JZ. In addition, it is preferable that the suction cup engaging portion 84A faces the joint engaging portion 84B.

  The suction cup engaging portion 84A is preferably formed in an arc shape. Thus, when the frame 2 is connected to the suction cup 30, the frame when hung on a wall, such as the one with the highest arbitrary side (see FIG. 1) or the one with the highest corner (see FIG. 4) The posture of 2 can be adjusted as appropriate. The suction cup engaging portion 84A is preferably engaged with the engaging groove 30BM (see FIG. 8B). Thereby, it becomes difficult for the protrusion 30B to come off from the suction cup engaging portion 84A. Moreover, it is preferable that the joint engaging part 84B is formed linearly. Furthermore, when the frame 2 is hung on the wall, the direction in which the force is applied to the main body 81 and the joint engaging portion 84B are preferably orthogonal. That is, in the case where the arbitrary side is the top (see FIG. 1), the direction in which the force is applied and the direction of the joint engaging portion 84B are preferably oblique 45 ° perpendicular to each other. In the case where the corner is the top (see FIG. 4), it is preferable that the direction in which the force is applied is the vertical direction, and the joint engaging portion 84B is the horizontal direction. Thereby, the posture of the frame 2 when it is hung on the wall is stabilized.

  Bending portions 84C are preferably formed on both sides of the joint engaging portion 84B. When the engaging portion 20JZ is engaged with the joint engaging portion 84B by the bent portion 84C, the movement of the engaging portion 20JZ along the joint engaging portion 84B can be restricted. In order to facilitate the engagement / disengagement operation of the joint 20J, the intersecting angle between the bent portion 84C and the joint engaging portion 84B is 90 ° or more and preferably less than 180.

  The slit forming pair 85 is a part of the main body 81 and forms a slit 81S. The slit forming pair 85 has a first slit end 85A and a second slit end 85B. The first slit end 85A and the second slit end 85B can transition between an approaching state (see FIG. 10A) and a separation state (see FIG. 10B) by deformation of the main body 81. While the first slit end portion 85A and the second slit end portion 85B are close enough to restrict the passage of the engaging portion 20JZ and the protruding portion 30B in the approaching state (see FIG. 10A), they are separated from each other. In the state (see FIG. 10 (B))), they are far enough to allow passage of the engaging portion 20JZ and the protrusion 30B. The slit forming pair 85 is biased to the approaching state (see FIG. 10A). When a predetermined external force is applied, the slit forming pair 85 is separated (see FIG. 10B), and the external force is solved. If it is touched, it will be in an approach state (refer to Drawing 10 (A)).

  Here, the relationship between the relative sizes of the engaging portion 20JZ and the protrusion 30B may be changed according to the priority of the restriction of passage of the slit 81S. For example, when it is desired to preferentially perform the protrusion 30B over the engaging portion 20JZ for restricting passage of the slit 81S, it is preferable to make the diameter of the protrusion 30B larger than the size of the engaging portion 20JZ.

  Next, a method for using the engaging member will be described. When an external force in the thickness direction T is applied to the main body 81, the main body 81 transitions from the approaching state shown in FIG. 10A to the separated state (see FIG. 10B). As a result, passage of the protrusion 30B in the slit 81S is allowed. Here, when the external force is released, the main body 81 returns to the approaching state shown in FIG. Thereby, the engaging member can be suspended from the protrusion 30B (FIG. 10B).

  When an external force in the thickness direction T is applied to the main body 81 again, the main body 81 transitions from the approaching state shown in FIG. 10 (A) to the separated state (see FIG. 10 (B)), resulting in the engaging portion 20JZ in the slit 81S. Is allowed to pass. The second slit end portion 85B is passed through the slit forming pair 85 in the separated state (FIG. 10B) in the order of the first opening 20XL, the communication hole 20XX, and the second opening 20XL. Thereafter, when the external force in the thickness direction T is released, the slit forming pair 85 enters an approaching state (FIG. 10A), and the passage of the engaging portion 20JZ in the slit 81S is restricted. As a result, the engaging member can connect the suction cup 30 and the joint 20J (FIG. 8C). Here, since the thickness of the curved part and the straight part which comprise the main body 81 is thin compared with the width | variety of a curved part or a linear part, it is easy to deform | transform into the thickness direction T rather than the surface direction S (FIG. 10). As a result, the engaging / disengaging operation of the engaging portion 20JZ from the engaging member can be performed by the external force in the thickness direction T. When the slit forming pair 85 is in the approaching state (FIG. 10A) and the connecting portion 20JC is suspended from the main body 81, the engaging portion 20JZ restricts the passage of the protrusion 30B through the slit 81S. It is preferable to arrange it at a position (FIG. 8C, FIG. 11 and FIG. 13 described later). Thereby, drop-off of the protrusion 30B can be prevented more reliably.

  In the above embodiment, an arc shape is adopted as the shape of the suction cup engaging portion 84A. However, the present invention is not limited to this, and may be an elliptical arc shape or a curved line.

  In the above-described embodiment, the first side surface 20ML and the second side surface 20MR that intersect with each other are used as the locations where the first opening 20XL and the second opening 20XL are formed. However, the present invention is not limited to this, and is on the same plane. There may be. That is, the first opening 20XL and the second opening 20XR may be formed in the joint 60 and the T-shaped joint shown in FIG. 7 without being limited to the joint 20J.

  In the above embodiment, the restriction and allowance of the passage of the engaging portion 20JZ and the protruding portion 30B are switched by the transition between the approaching state and the separated state, but the present invention is not limited to this, and the engaging portion 20JZ and the protruding portion 30B. The restriction and allowance of the passage of either one of them may be switched.

  The position at which the slit 81S is formed in the main body 81 is not particularly limited as long as the engaging portion 20JZ can be engaged and disengaged from the engaging member. It should be noted that when the connecting portion 20JC is suspended from the main body 81 so that the suction cup engaging portion 84A engages with the protrusion 30B, the slit 81S is preferably separated from the protrusion 30A.

  In the above embodiment, the slit 81S is provided between the suction cup engaging portion 84A and the joint engaging portion 84B. However, the present invention is not limited to this, and the slit 81S may be provided in the middle of the joint engaging portion 84B. Good (see FIG. 11). In this case, the slit forming pair 85 also serves as the joint engaging portion 84B.

  As shown in FIG. 12, in the above embodiment, the shape of the main body 81 includes an arc-shaped portion CK including the suction cup engaging portion 84A, and a straight portion SL corresponding to the joint engaging portion 84B and the bent portion 84C. The present invention is not limited to this. The gravity center position G1 (FIG. 12A) of the main body 81 when the suction cup engaging portion 84A is engaged with the protrusion 30B is the main body when the adjacent portion 84R of the suction cup engaging portion 84A is engaged with the protrusion 30B. Preferably, the shape is lower than the center of gravity position G2 of 81 (FIG. 12B). As a result, the transition from the state where the protrusion 30B is engaged with the suction cup engaging portion 84A (FIG. 12A) to the state where the protrusion 30B is engaged with the adjacent portion 84R (FIG. 12B) occurs. The transition from the state where the protrusion 30B is engaged with the adjacent portion 84R (FIG. 11B) to the state where the protrusion 30B is engaged with the suction cup engaging portion 84A (FIG. 11A) is likely to occur. Become. As a result, the main body 81 can easily take a posture in which the suction cup engaging portion 84A is engaged with the protruding portion 30B. Therefore, the position of the slit 81S when the connecting portion 20JC is suspended from the main body 81 can be removed from a desired position (a position where the protrusion 30B and the connecting portion 20JC are likely to drop off).

  As shown in FIG. 13, the joint engaging portion 84B is provided as a pair on the insertion hole 81X side of the slit forming pair 85 (the first slit end portion 85A and the second slit end portion 85B). Also good. The joint engaging portions 84B protrude from the slit forming pair 85 toward the center of the insertion hole 81X. The amount of protrusion of the joint engaging portion 84B is preferably increased toward the slit 84S. That is, when the connecting portion 20JC is suspended from the main body 81 so that the engaging portion 20JZ engages with the joint engaging portion 84B, the height of the joint engaging portion 84B increases toward the slit 84S. As a result, the slit forming pair 85 is biased in the direction in which the slit 84S becomes narrower, and can more reliably prevent the protrusion 30B and the connecting portion 20JC from falling off.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
