Description

  The present invention relates to a frame capable of opening and closing a front frame, and more particularly to a frame capable of easily setting a work such as a painting from the surface with the frame opened at the front.

  Frames have been developed that have a frame that can be opened and closed on the front side, and it takes time and effort to disconnect and assemble the corners when setting or replacing works such as paintings and photographs. Further, the structure for fixing after assembly requires a complicated structure in order to attach components such as a lock member and a stopper.

  As these examples, Japanese Patent Application Laid-Open No. 2005-168945 “Frame” and Utility Model Registration No. 3083507 “Front Opening Frame” are disclosed.

  JP 2005-168945   Utility model registration No. 3083507

  In Japanese Patent Application Laid-Open No. 2005-168945 described above, this type of connecting device takes time and effort to disconnect or assemble the corner portion when setting or replacing works such as paintings. Further, a covering member is covered on the surface of the corner joint connecting the lower frame, and this covering member has to be moved outward when replacing a picture or the like.

  Also, in the case of the utility model registration No. 3083507 described above, a corner connecting bracket is required, and the display frame is closed after the four corners of the display object are fitted in the recesses provided inside the connecting bracket. It was to fix things.

    As a result of diligent research to solve such problems, the frame that can be opened and closed according to the present invention has a display frame in the concave portion provided inside the connecting fitting each time a picture is replaced. It does not require the work of fitting the four corners and can easily set paintings and the like from the surface, and is configured as follows.

  Through the L-shaped member formed integrally with the back side corner parts, the base frame of four sides is framed in a rectangular shape, and the edge of the front frame is fitted to the edge receiving portion of the base frame, The front frame can be opened and closed via the edge receiving part, and a metal toggle function leaf spring is fitted between the leaf spring abutting part inside the front frame and the leaf spring abutting part of the base frame. The metal toggle function leaf spring is configured to be biased to open and close the front frame, and the corner part for surface decoration is separated from the corner part on the back side. An insertion portion protruding from the side of the corner part is inserted from one end of the front frame and fixed integrally with the front frame, and the decorative corner part is fixed to the front frame. The spring property of the push-up spring member is such that it is opened and closed in accordance with the opening and closing of the screen so that no step is generated between the corner part for surface decoration and one end of the adjacent front frame. The strength is set to be weaker than the spring strength of the metal toggle function leaf spring, and screw holes that can be easily installed when the front frame is opened are provided in the back corner parts. A frame that can be opened and closed is provided.

  According to the frame of the present invention that can open and close the front frame, since the frame can be opened at the front, it is easy to set or change the posting, and even if the thickness of the posting is different, special operation is possible. The spring strength of the push-up spring member is greater than the spring strength of the metal toggle function leaf spring so that there is no step between the corner part for surface decoration and one end of the adjacent front frame. Since it is set weakly, it is easy to mount paintings and photographs when the front frame is opened.

It is a top view of the frame which can open and close the front frame of this invention. It is a rear view of FIG. It is the partial top view which open | released the front frame. It is a disassembled perspective view of the junction part of a front frame and the corner parts for surface decorations It is a perspective view of a back side corner part. It is an expanded sectional view of the AA line of FIG. It is a perspective view of a push-up spring member.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
In the drawings, FIG. 1 is a plan view of a frame that can be opened and closed according to the present invention. FIG. 2 is a rear view of FIG. FIG. 3 is a partial plan view with the front frame opened. FIG. 4 is an exploded perspective view of the joint between the front frame and the surface decoration corner part. FIG. 5 is a perspective view of the back side corner part. FIG. 6 is an enlarged cross-sectional view taken along line AA in FIG. FIG. 7 is a perspective view of the push-up spring member.

  Through the L-shaped member 53 formed integrally with the back side corner part 5, the base frame 4 with four sides is framed in a rectangular shape.

  As shown in FIG. 3, the L-shaped member 53 formed integrally with the back side corner part 5 and the base frame 4 are connected to the L-shaped member 53 in contact with the base frame 4 with set screws 52, 52. It is firmly fixed.

  As shown in FIG. 6, the end edge portion 12 of the front frame 1 is fitted to the edge receiving portion 42 of the base frame 4, and the front frame 1 is configured to be openable and closable via the edge receiving portion 42. Yes. The cross section of the front frame 1 in the opened state is indicated by a dotted line in FIG.

  Further, as shown in FIG. 6, seven metal toggle functional leaf springs are fitted between the leaf spring abutting portion 11 inside the front frame 1 and the leaf spring abutting portion 41 of the base frame 4, and the metal The spring function of the toggle function leaf spring 7 is configured to be biased when the front frame 1 is opened and closed.

  The corner part 2 for surface decoration is completely separated from the corner part 5 on the back side, and an insertion portion 21 protruding from the side surface of the corner part 2 for surface decoration is inserted from one end of the front frame 1 as shown in FIG. As shown in FIG. 3, the surface decoration corner part 2 is configured to be integrally opened as the front frame 1 is opened. When the front frame 1 is closed to the inside, it is closed in the same manner as shown in FIG.

  At this time, since the spring strength of the push-up spring member 3 is set to be weaker than the spring strength of the metal toggle function leaf spring 7, it is between the corner part 2 for surface decoration and one end of the adjacent front frame 1. There is no difference in level.

  Screw holes 51 that can be easily attached when the front frame 1 is opened are provided in the back corner part 5.

  A frame that can be easily opened and closed on the front frame with the front frame of the present invention opened on the front, and can be used very conveniently at home and school. .
