Description

[Detailed Description of the Invention] Field of Application This invention relates to a device for securing works in picture frames, especially deep picture frames.

Background of the invention In general, picture frames with a large depth dimension give a luxurious impression and are suitable for displaying expensive large-scale paintings, calligraphy, and other works. On the other hand, in recent years, frame frames of picture frames have increasingly been made of extruded aluminum.

Therefore, there has been a demand for a work attachment device that can securely and easily attach works to deep picture frames that use extruded aluminum for the frame ribs.

Prior Art As a work fixing device that can meet this demand, the applicant first installed a tongue piece on a slide plate that can be inserted into a guide groove provided on the frame bone and slid in the longitudinal direction of the frame bone. , presented a device that was equipped with a fastening fitting formed by screwing a loosely fitted bolt onto the tongue piece to allow the pressing piece to press the work to rotate freely and restrain its vertical movement (Jitsugan Sho 55). −084511).

However, with this device, the slide plate can only be inserted into the guide groove provided on the frame from the end of the frame, so it is necessary to insert the slide plate into the guide groove provided on the frame only from the end of the frame. Since it is necessary to insert the slide plate in advance, it is extremely inconvenient to attach an arbitrary number of fastening metal fittings to arbitrary positions in the longitudinal direction of the frame.

Purpose of the invention Therefore, this invention is a device for fixing works of art on a picture frame, which is equipped with fastening fittings that can be used in any number of pieces at any position in the longitudinal direction of the frame, and can be easily attached even after the frame is assembled. The purpose is to provide.

Structure of the invention The structure of this invention to achieve the above object is to stand a bolt between the upper and lower halves of the U-shaped piece so as to be able to freely rotate and restrain its vertical movement, and a pressing piece screwed onto the bolt presses the bolt. One piece of the fastening metal fitting, which can be moved up and down between the upper and lower pieces by rotation, is engaged with a small protrusion on the first protruding wall provided on the frame, and the base portion is attached to the second protruding wall. By making contact with the frame body and using appropriate locking means, any number of pieces can be used at any position in the longitudinal direction of the frame bone, and can be easily attached even after the frame body is assembled. The gist is:

Configuration of example A first embodiment thereof is shown in FIGS. 1 to 4.

The fastening fitting 10 has a U-shaped piece 14 consisting of a base part 11, an upper piece 12, and a lower piece 13, and the upper and lower pieces 12, 1
A bolt 17 is inserted through the small holes 15 and 16 provided in the bolt 3, and a pressing piece 18 is screwed through a screw hole 19 at one end of the bolt 17. The bolt 17 is loosely inserted into the small holes 15 and 16, and a stopper ring 21 made of a spring material is press-fitted into the lower end of the bolt 17 as a non-threaded portion to prevent its vertical movement. Further, between the lower neck of the bolt 17 and the upper piece 12, one end thereof is a bent part 22 that engages with one piece of the upper piece 12, and the other end is a rounded part 23, which is bent approximately on an extension line of the base part 11. A leaf spring 24 in the shape of a bent waist with an eye is clamped and used as a means for locking the fastening fitting 10 and the frame rib 30.

The pressing piece 18 has a screw hole 19 at one end for screwing into the bolt 17, and a hole 20 with a downwardly directed annular projection 25 at the other end.

On the other hand, a frame rib 30 serving as the frame of the picture frame is provided in its longitudinal direction with a first projecting wall 31 having a small protrusion 32 erected at its end, and a second projecting wall 33 parallel to the first projecting wall 31. , the position and height of the latter are spaced apart from the former by an amount equal to the width of the lower piece 13 of the fastening fitting 10, and are larger than the former by an amount approximately equal to the height of the base portion 11 (FIG. 3). At the tip of the second projecting wall 33, a frame bone 30 is provided.
The protrusion 3 facing the protrusion 36 erected from the rear edge
5 is erected, and a groove 34 is formed between both the protrusions 36 and 35. There is a protrusion 3 on the anterior edge of the frame bone.
7 is provided parallel to the front surface of the picture frame.

The length of the leaf spring 24 is such that when the base portion 11 abuts the second projecting wall 33, the rounded portion 23 at the tip can reach the groove 34 across the projecting rim 35, and the length of the pressing piece 18 The length is such that it can extend toward the inside of the picture frame beyond the protrusion 37 on the front edge of the frame bone in the same condition.

Effect of the embodiment The fastening fitting 10 can be attached at any position in the longitudinal direction of the frame 30.
When the end of the lower piece 13 is engaged with the small protrusion 32 provided at the tip of the first protruding wall 31 and the base portion 11 is brought into contact with the second protruding wall 33, the rounded tip of the leaf spring 24 23 slides on the protrusion 35 at the tip of the second projecting wall 33 and falls into the groove 34, while the tip of the protrusion 35 pushes up the leaf spring 24 (FIG. 4). Therefore, the restoring force of the leaf spring 24 acts in the direction of pulling up the fastening fitting 10 toward the tip of the second projecting wall 33, but the lower piece 13
is engaged with the small protrusion 32 at the tip of the first projecting wall 31, so the fastening metal fitting 10 is attached to the frame frame 30 and fixed. Moreover, since the grooves 34, the protruding walls 33, 31, and the small protrusions 32 are all provided continuously in the longitudinal direction of the frame rib 30, the fastening fittings 10 can be attached before or after completing the assembly of the frame frame. Regardless, any number can be provided at any position in the longitudinal direction of the frame rib 30.

On the other hand, the work is mounted with its front surface in contact with the protrusion 37 at the front end of the frame rib 30 and its side surface in contact with the first projecting wall 31 (double-dashed line in FIG. 3). Therefore, with the pressing piece 18 at a position perpendicular to the frame bone 30, the bolt 17
When the bolt 17 is rotated, the thread of the bolt 17 is pressed against the pressing piece 18.
Since it moves up and down, the work can be sandwiched and fixed between the protrusion 37 and the pressing piece 18. At this time, a hole 20 with an annular convex portion 25 is formed at the tip of the pressing piece 18.
Since this annular protrusion 25 is provided, the annular convex portion 25 bites into the back side of the work, and the work is fixed more completely.

Furthermore, by changing the lengths of the base portion 11 and the bolts 17, it is possible to accommodate a frame of any depth, and by changing the lengths of the upper and lower pieces 12, 13 and the pressing piece 18, it is possible to accommodate a frame of any width. Furthermore, since the position of the pressing piece 18 can be moved between the upper and lower pieces 12 and 13, the thickness of the work can be adjusted very easily.

Other Embodiments and Effects FIGS. 5 to 7 show the second to fourth embodiments, respectively, and FIGS. 8 and 9 show the fifth embodiment.

In the second embodiment, a protrusion 51 is formed by extending the tip of the second protruding wall 33 of the frame 30, and the leaf spring 24 is engaged with the protrusion 51 (FIG. 5).

In this case, since the grooves 34 of the first embodiment are omitted, the frame structure is simplified and the cost of the extrusion mold can be reduced.

In the third embodiment, a beam member 62 having a large number of parallel uneven stripes 61 is erected at the tip of the second projecting wall 33, and the rounded portion 23 of the leaf spring 24 engages with the uneven strip 61. (FIG. 6), when the fastening metal fitting 10 is attached, a light shock feeling can be obtained when the rounded portion 23 rides over the uneven strip 61, so it is convenient for attachment to a part that cannot be seen directly.

In the fourth embodiment, a small bolt 72 is screwed into a screw hole 71 provided on the back surface of the base portion 11 of the fastening fitting 10 to secure the leaf spring 24, and the plate spring 24 is fixed to the groove 73 provided on the second projecting wall 33. It is intended to engage (7th
figure).

In addition to the short dimensions of the leaf spring 24, the bolt 17
Since the fastening together with the fastener is eliminated, the fastening fitting 10 can be installed more completely.

In the fifth embodiment, a part of the upper piece 12 of the fastening fitting 10 is bent in the opposite direction to form a tongue piece 81 having a screw hole 82 (FIG. 8), and the bolt 83 is pressed against the beam member 84 to fasten the fitting. This completes the attachment of the fitting 10 (FIG. 9).

Since the leaf spring 24 is not required, the cost can be reduced, and since the fastening fitting 10 is completely attached, there is no vibration,
There is no possibility that the fastening fitting 10 will come off from the frame rib 30 due to impact or the like.

Effects of the invention As explained above, according to this invention, a bolt is placed between the upper and lower halves of the U-shaped piece, and a piece of the fastening metal fitting that moves the pressing piece up and down by the rotation of the bolt is attached to the frame. It is engaged with a small protrusion on the first protruding wall provided on the bone, and its base portion is brought into contact with the second protruding wall, and then the frame is fixed at any position in the longitudinal direction of the frame bone using an appropriate locking means. Since the fasteners can be attached at any position on the frame, any number of fastening fittings can be easily attached at any position on the frame even after the frame has been assembled.

In addition, the length of the base, the length of the upper and lower pieces, and the length of the pressing piece of the fastening bracket can be changed according to the dimensions of the frame, so it can be used with any depth and width of the frame. Furthermore, since the height of the pressing piece can be freely moved between the upper and lower pieces, the thickness of the work can be adjusted very easily.
