Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front opening / closing type frame for holding a picture, a photograph, a jigsaw puzzle or the like and decorating it on a wall or standing on a desk.

[0002]

2. Description of the Related Art Heretofore, a frame for holding a picture, a photograph or the like and hanging it on a wall or the like has been widely known. However, each time a picture or the like in the frame was exchanged, it was necessary to remove the frame from the wall or the like and exchange the picture or the like from the back side of the frame, that is, the side opposite to the viewing side. For this reason, exchanging paintings and the like was very time-consuming.

In order to solve the above problems, for example, a picture or the like from the front side of the frame, that is, the viewing surface side, with the frame being hung on a wall or the like, or once removed from the wall or the like. There is known a front opening / closing frame that can be replaced.

The front opening / closing frame is composed of, for example, four frame frames. The frame frame has a main body that basically supports a painting, a photograph, and the like from the back side, and an opening / closing portion hinged to the main body. The opening and closing part is openably and closably connected to the front side of the frame by using the hinge joint as a fulcrum, and holds the end of the contents such as paintings and photographs from the front side of the frame in the closed state. There is. Further, the main body portion and the opening / closing portion are generally engaged with each other via an engaging portion, and the engagement maintains the closed state of the opening / closing portion.

[0005]

However, in the above-mentioned conventional front opening / closing type frame, the main body part and the opening / closing part are manufactured separately and then connected by high frequency welding or the like to form a frame frame. ing. Therefore, a large number of parts in the manufacturing stage and a connecting process are required,
Therefore, there are problems that the number of manufacturing processes is large, and that it is difficult to reduce the cost and reduce costs.

Further, since the opening / closing section maintains the opening / closing function,
It is necessary to be hingedly connected to the main body, but if this part is configured by a number or the like, the structure of this part becomes complicated due to the number mounting structure, and the number of mounting parts and the number of mounting steps increase. On the other hand, there is also a method of configuring the hinge part with a soft resin, but since the main body part and the opening / closing part are configured as separate parts, it is not easy to join both parts with a soft resin after manufacturing these parts. It is difficult and the manufacturing conditions are extremely narrow. Further, even if they can be joined, there is a possibility that the joining reliability, for example, durability against repeated use, joining reliability, etc. may be lacking.

Further, in the conventional front opening / closing type frame, the load of the stored item is other than the load received from the back side of the stored item, that is, the load received from the side of the stored item or the front side of the frame is directed downward. The load received from the front side of the stored items, which is generated in the case of being, is basically all received by the opening / closing section, so that the engaging force between the main body section and the opening / closing section cannot withstand the load, The opening / closing part may be deformed, and the opening / closing part may be unexpectedly opened.

The object of the present invention is to reduce the number of parts, to manufacture easily and inexpensively with a small number of steps, and to separate the functions of the main body part and the opening / closing part clearly so that a large load is basically applied to the opening / closing part. It is to provide a durable and reliable front opening / closing frame that is not added.

[0009]

In order to solve the above problems, a front opening / closing frame according to the present invention comprises a plurality of frame frames each having a main body and an opening / closing section, and the opening / closing section is a frame. In the frame configured to be openable and closable with respect to the front side, the main body of the frame frame and the opening / closing part are integrally molded of resin.

Further, the front opening / closing type frame according to the present invention comprises a plurality of frame frames having a main body and an opening / closing portion, and the opening / closing portion is configured to be openable / closable with respect to the front side of the frame. In the frame, the frame frame is provided with a hollow main body for holding the contained object on one surface, and is erected on the one surface of the main body so as to face the edge of the contained object. A load holding portion having a recessed portion that opens in opposition to the main body portion, and an opening / closing portion that is openably and closably connected to the main body portion via a hinge portion and has a convex portion that can engage with the recessed portion of the load holding portion. In addition, the main body portion, the load holding portion, and the opening / closing portion are integrally formed of resin.

It is desirable that the load holding portion extends to the side opposite to the main body portion with respect to the contact surface of the opening / closing portion with respect to the stored object.

It is desirable that the hinge portion is formed of a resin softer than the resin forming the other portions.

It is preferable that at least the engaging portion between the concave portion of the load holding portion and the convex portion of the opening / closing portion has a locking structure for restricting the displacement of the opening / closing portion toward the front side of the frame.

Then, by connecting adjacent ends of the plurality of frame frames to each other through a frame corner connector which can be inserted into the hollow portion of the main body of each frame frame, a frame having a desired shape can be easily formed. be able to.

It is desirable that the frame corner connector be formed in an H-shaped cross section. Further, it is desirable that the main body portion and the frame corner connecting tool are provided with engaging portions that can be engaged with each other.

In the front opening / closing frame as described above,
The main body portion and the opening / closing portion are integrally molded with resin (for example, extrusion molding). That is, since the frame frame can be manufactured in one process, it is possible to reduce the manufacturing process and the number of parts as compared with the case where the frame frame is manufactured separately.
Cost reduction can be achieved. The method for manufacturing the frame frame is not particularly limited, but an extrusion molding method is preferable. The resin is also not particularly limited, and examples thereof include polyvinyl chloride and polyethylene.

Further, if a load holding portion facing the edge of the contained object is erected on one surface of the main body of the frame frame for holding the contained object, the contained object side when suspending the frame etc. The load holding section can bear the load from the section. Since the load holding portion is integrally formed with the main body portion, the above-mentioned load is not applied to the opening / closing portion as in the conventional case, and it is possible to reliably prevent the opening / closing portion from being unexpectedly opened when the frame is suspended. be able to.

Further, by adopting a locking structure for restricting the displacement of the opening / closing part to the front side of the frame, the engaging part between the concave part of the load holding part and the convex part of the opening / closing part adopts the opening / closing part on the front side of the frame. Even if a heading load is applied, the load can be received by the load holding portion, and by extension, the body portion integrally formed with the load holding portion. Therefore, even when a load is applied to the frame front surface side, such as when the frame front surface side faces downward, it is possible to prevent the opening / closing portion from being deformed or the opening / closing portion being accidentally opened.

Further, by extending the load holding portion to the side of the main body opposite to the contact surface of the opening / closing portion with respect to the contents, the contents, for example, a transparent sheet or the like accommodated in the uppermost layer as will be described later, acts as the load holding portion. It is possible to surely prevent a problem such as getting over and slipping. Further, since all the contained items can be held at a predetermined position, the function of the load holding section is surely fulfilled.

Further, since the frame frame is integrally molded with resin (for example, extrusion molding), the resin forming the hinge portion is a soft resin, and the resin portion can easily have the hinge function. Since the desired hinge portion can be formed only by integral molding without requiring a joining process, the process becomes extremely simple. Moreover, since the soft resin forming the hinge and the hard resin on both sides of the hinge are melt-bonded in the same step, strong bonding characteristics and durability are naturally ensured.

Then, a frame corner connector is inserted into the hollow portion of the main body to connect adjacent ends of the frame frame to each other to easily form a front opening / closing frame having a desired shape (for example, a quadrangle). be able to.

Further, by forming the frame corner connector to have an H-shaped cross section to increase the rigidity, it is possible to effectively suppress the twisting of the main body.

Further, if the main body and the frame corner connecting tool are provided with the engaging portions which can be engaged with each other, the frame corner connecting tool is simply inserted into the main body of the frame frame to obtain a desired one-touch operation. It becomes possible to assemble the frame, and it is possible to facilitate the assembly,
It is also possible to improve the connection strength between the frame frame and the frame corner connector.

In the figure, reference numeral 1 denotes the entire frame, which is a front opening / closing frame. In this embodiment, the frame 1 is formed into a rectangular (quadrilateral) frame by using four frame frames 2. The frame frame 2 has a main body portion 3 and an opening / closing portion 4, and the opening / closing portion 4 is openably / closably connected to the main body portion 3 via a hinge portion 5. That is, the opening / closing part 4 is rotatable about the hinge part 5 in the direction of the arrow in FIG. 3 and can be opened / closed with respect to the front side of the frame (viewing side).

As shown in FIGS. 2 and 3, the main body 3 is formed in a hollow shape having a hollow portion 6. In addition, on the one surface 7 of the main body portion 3, the container 8 held on the one surface 7 is provided.
(In this embodiment, the mount 8a, the painting or photograph 8b,
A load holding portion 10 is erected so as to face the edge 9 of the transparent sheet 8c). For jigsaw puzzles,
Each piece is housed in the mount. The load holding portion 10 extends on the side opposite to the main body side with respect to the contact surface 12 of the opening / closing portion 4 with respect to the article 8 which will be described later. (For example, it extends about 0.5 mm or higher.) Further, the load holding portion 10 is provided with a concave portion 11 that is open facing the opening / closing portion 4. The recess 11 has a larger inner depth than the entrance.

The opening / closing section 4 is connected to the end of the other surface 20 opposite to the one surface 7 of the main body section 3 via a hinge section 5, and rises along the standing direction of the load holding section 10. It is formed in a shape that curves toward the one surface 7 side later.
At the tip of the curved portion, there is provided an abutting portion 13 for the container 8 having an abutting surface 12 facing the one surface 7 in the closed state of the opening / closing portion 4.

Further, the opening / closing part 4 is provided with a convex part 14 which can be engaged with the concave part 11 of the load holding part 10, and the concave part 11 and the convex part 14 constitute an engaging part 17. Convex portion 14
The front end portion is set to be larger than the neck portion thereof, and the elasticity of the neck portion of the convex portion 14 is used to fit the concave portion 11 into the concave portion 11. The closed state of the opening / closing section 4 is maintained through the engagement of the engaging section 17, and the contained object 8 is sandwiched between the one surface 7 and the contact surface 12 (FIG. 2).

The engagement of the engaging portion 17 is specifically as follows. That is, with the convex portion 14 inserted in the concave portion 11, the opening / closing portion 4 is opened in the opening direction (see FIG.
The force to open in the direction of arrow A in FIG.
The closed state is maintained and the movement in the direction of the arrow A is achieved by the engagement between the inner depth of the inside and the tip side portion of the convex portion 14 and the engagement between the opening inlet portion 15 of the concave portion 11 and the neck portion 16 of the convex portion 14. Are being blocked. Further, when a force in the direction of arrow B is applied to the opening / closing part 4 (for example, when the front side of the frame faces downward), a deforming force in the same direction is applied to the opening / closing part 4 or a load is applied to the hinge part 5. However, the load in this direction is also received by the engaging portion 17.
That is, the engaging portion 17 including the concave portion 11 and the convex portion 14 constitutes a locking structure that restricts the displacement of the opening / closing portion 4 toward the front surface side of the frame. As described above, the load holding unit 10 also directly receives the load from the side portion of the housed object 8, that is, the load in the direction of arrow C in FIG.

In this embodiment, the main body portion 3, the load holding portion 10 and the opening / closing portion 4 of the frame frame 2 are integrally molded (extruded) with polyvinyl chloride resin, but the hinge portion 5 has Resin (soft resin of the same kind) softer than other parts (main body 3 and opening / closing part 4) is used,
The hinge function is exhibited by utilizing the soft property.

A plurality of frame frames 2 as described above and a plurality of frame corner connectors 18 described below (in the present embodiment, four frame frames 2 and frame corner connectors 1) are provided.
8) is connected to form the frame 1 having a predetermined shape. Specifically, the frame frame 2 and the frame corner connector 18 are connected by inserting the frame corner connector 12 into the hollow portion 6 of the main body 3 (FIGS. 2 and 3).

As shown in FIG. 4, the frame corner connector 18 has an H-shaped cross section. In the present embodiment, the frame corner connector 18 is made of resin, but the invention is not limited to this, and the frame corner connector 18 may be made of aluminum, aluminum alloy, or the like.

Further, the frame corner connector 18 and the main body 3 are provided with engaging portions 19 which can be engaged with each other. That is, when the connector 18 is inserted from the direction of the arrow in FIG.
In the hole 22 formed in the recess 21 of the other surface 20 of the main body 3,
An elastically deforming portion 23 integrally provided on the frame corner connecting tool 18 is fitted into the frame corner connecting tool 18 so as to be engaged with each other. The elastically deformable portion 23 is elastically deformed and then elastically restored to fit into the hole 22.

In the front opening / closing frame 1 according to this embodiment, the main body portion 3 and the opening / closing portion 4 of the frame frame 2, the load holding portion 10 and the hinge portion 5 are integrally formed of resin. That is, since the frame frame 2 can be manufactured in one step, the number of manufacturing steps and the substantial number of parts can be reduced, and efficient cost reduction can be achieved.

Further, on the one surface 7 of the main body portion 3, the contents 8
Since the load holding portion 10 facing the end edge 9 of the frame 8 is erected, the load of the stored object 8 when the frame 1 is suspended acts on the load holding portion 10. For this reason, the load of the contents 8 is not applied to the opening / closing part 4, and the opening / closing part 4 can be reliably prevented from being opened unexpectedly.

Further, the engaging portion 17 between the main body portion 3 and the opening / closing portion 4
Has a locking structure for restricting the displacement of the opening / closing part 4 to the front side of the frame as described above, so that the opening / closing part 4 can be opened unexpectedly even when a load acts in the direction of arrow B in FIG. It can be surely prevented.

Further, in this embodiment, since the load holding portion 10 extends beyond the contact surface 12 of the opening / closing portion 4 toward the main body side, the load holding portion 10 securely locks all the contents 8. Therefore, it is possible to reliably avoid a situation in which the end edge 9 of the container 8 gets over the load holding portion 10 and shifts toward the opening / closing portion 4 when the frame 1 is suspended. In addition, in the present embodiment, the load holding portion 10 extends about 0.5 mm from the contact surface 12 to the side opposite to the main body side, but may be further extended in the above direction as long as the opening / closing operation of the opening / closing portion 4 is not hindered. It is possible.

Further, since the hinge portion 5 is made of a resin softer than other portions, the hinge portion 5 is provided with the elastic deformation characteristics required, and at the same time, the rigidity required for other portions is also provided. Can be given. Therefore, the contradictory characteristics required of the hinge part 5 and other parts can be simultaneously satisfied with good balance. Further, since the soft resin forming the hinge portion 5 is also used for integral molding, there is no problem in the jointability with the surrounding hard resin, and the strong jointability and the hinge portion are not present. Both excellent durability against repeated use of 5 is naturally ensured. Furthermore, by forming the hinge portion 5 with a soft resin, even if there is a slight deviation in the positional accuracy between the concave portion 11 and the convex portion 14 which form the engaging portion 17, the hinge portion 5 is made to have elasticity. The deformation can be easily absorbed, and the elastic restoration of the hinge portion 5 can surely realize a desired engagement state in the engagement portion 17.

By connecting the frame frames 2 by using the frame corner connector 18, it is possible to easily assemble a frame having a desired shape (for example, a quadrangle, a triangle, or a polygon of a larger size) very easily. In addition, in order to form the frame 1 in a shape other than the quadrangle shown in the present embodiment, it is only necessary to slightly modify the both end shapes of the frame frame 2 and the shape of the frame corner connector 18.

Further, since the frame corner connector 18 is formed in an H-shaped cross section as shown in FIG.
When it is inserted into the hollow portion 6, it plays a role of a reinforcing member that reinforces the end portion of the main body portion 3 from the inside. Therefore,
Even if the main body 3 is hollow, sufficient strength against twisting can be secured. The cross-sectional shapes of the hollow portion 6 and the frame corner connector 18 are not limited to the shapes of this embodiment. For example, a convex portion (raised portion) extending toward the inside of the hollow portion 6 is formed on the upper portion of the hollow portion 6 in FIGS. 2 and 3, and the frame corner connector 18 having an H-shaped cross section is also provided on the upper portion of the drawings. By engaging with the main body 3, the main body 3 and the frame corner connecting tool 18 can be connected more firmly.

Further, the frame corner connector 18 is provided with the engaging portion 1
9 prevents the main body 3 from slipping out in the direction opposite to the arrow in FIG. 5, but for example, the frame corner connector 18 with the elastically deforming portion 23 lightly pushed upward. It is also possible to easily release the engagement between the two by moving the in the direction opposite to the arrow. In other words, since both can be easily attached and detached, it is possible to facilitate the disassembly and assembly of the frame 1 by the user or the like. Further, the frame frame 2 and the frame corner connector 18 can be separately distributed as needed. For example, even if it is shipped and sold in a disassembled state,
It is extremely easy for the purchaser to assemble.
