Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a frame hanging tool that is detachably attached to a frame as a connecting member for hanging a frame made of an extruded shape member such as aluminum on a wall, and a stand for the frame when standing on a table. The present invention relates to a frame hanger that can be diverted to legs.
[0002]
[Prior art]
To hang the frame on the wall, if it is made of wood, the hanging bracket is screwed to the back side of the frame, but if it is made of metal, the dovetail groove for inserting the corner coupling bracket of the frame is opened on the back side. A hanger is attached using a dovetail. In this case, the hanger is generally formed of plastic, and can be attached and detached by elastic deformation.
[0003]
On the other hand, in the past, when using a metal frame in the form of a stand, a plate-like support that can be hooked at the front end of the dovetail of the frame is used, and the other end is supported on a table to maintain the stand state. A proposal is made to make it possible (Japanese Utility Model Publication No. 61-105072). However, it does not have a stand leg that lifts and supports the picture frame, and the wall has a hole for fastening with a nail, so it has a function that allows the picture frame to be hung on the wall, but it is hung with a string etc. It was not suitable for use as a so-called hanger.
[0004]
[Problems to be solved by the invention]
Conventionally, if the suspension is made detachable as described above, it cannot be easily removed if the attachment is strong, and conversely, if it is easy to remove, the attachment becomes unstable. It was very difficult. Moreover, when used as a stand leg where the load on the frame is almost entirely applied, there is anxiety in terms of mounting strength and lack of reliability, and because it is enlarged, it was not suitable for finishing on the back side of the frame .
[0005]
In view of the above circumstances, the present invention can be easily attached to and detached from the frame of the frame, and the attachment is strong, and it can be used on the stand leg by attaching the support bar . An object of the present invention is to provide a frame hanging tool that is suitable for finishing on the back side and that can stably hang a ball chain as a hanging string .
[0006]
[Means for Solving the Problems]
To achieve the above object, the invention is a dovetail groove which opens to the rear surface is formed in a frame of the frame, a plastic hanger removably attaching to the dovetail groove, which for the frame on a table A support bar that supports the frame at the back is provided so that the stand support form can be taken up, and the tongue piece that protrudes in the outer peripheral direction of the frame and hangs the hanging string is refracted on the latching piece that fits into the dovetail groove. The hanging piece is formed in an elastically deformable curved shape that hangs down at the tip of the outer opening edge piece of the dovetail and that is in contact with the other inner surface of the dovetail by reversing the tip. An engaging claw that protrudes from the outer surface and hooks under the outer opening edge piece of the dovetail groove is formed, and the engaging claw is formed with a long and loose lower clearance angle slope and a short and steep upper clearance angle slope on the tongue, Make a through-hole to pass the hanging strap through the piece and pass it through Form a Dalma-shaped hole with a small hole above the large hole, and widen the opening so that at least the thickness of the small hole is a protrusion, and narrow the neck of the Dalma-shaped hole by the protrusion from the protrusion The frame of the frame is characterized in that it is formed so that the ball of the ball chain as a hanging string can be accommodated, and further, a cylindrical insertion port for attaching a support bar is provided at the center of the width of the latching piece. A hanger was constructed.
[0007]
[Action]
Since the frame hanger is constructed as described above, when attaching it to the frame, first insert the tip of the latching piece into the dovetail groove and hook it on the inner opening edge piece of the dovetail groove, and use it as a fulcrum for the tongue piece Press down. Then, the engaging claw rubs against the outer opening edge piece with a long curved lower clearance angle slope, and a boosting force that elastically deforms the latching piece at that time works. You can do the hooking operation. On the contrary, since the upper clearance angle slope of the engaging claw has a short steep shape, it is not easily detached. Also, since the dovetail has both inner and outer opening edge pieces, when not using a lifting tool, it can be attached with the tongue piece facing inward, but in this case, from the thin slim shape of the tongue piece, The final settlement is good.
[0008]
In addition, a through hole is provided in the tongue piece, and the through hole is formed into a Dalma-shaped hole. Since the through hole can be passed through the large hole and hung on the small hole, it is easy to attach the hanging strap. In addition , since the small hole is widely opened in a bowl shape, when a ball chain is used for the hanging strap, the ball is settled in the bowl-shaped recess and is stabilized.
[0009]
Moreover, since the tongue piece protrudes to the outer peripheral side of the frame, it can also be used as a stand leg when the frame is placed on a table (FIG. 7). In this case, the support means is not particularly limited, but it is convenient and rational because an insertion port for attaching the support rod to the latch piece is provided . Further, In this way, since the engaging claw is force Vb acts Gataku increasingly out by the force Va receiving a frame back tilted support rods may support the frame stable (Figure 3).
[0010]
【The invention's effect】
As described above, according to the frame hanging tool of the present invention, it can be easily attached to and detached from the frame of the frame by a one-touch operation, and handling such as when worn on the frame or when the back of the frame is finished is simplified. In addition, it is easy to finish well. Moreover, since the attachment is strong, not only can the frame be hung stably, but there is also an excellent effect that it is suitable for use as a stand leg when the frame is placed on a table.
[0011]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings.
[0012]
The drawing shows an embodiment, and the frame hanging tool P has a hook piece 5 protruding into the dovetail 3 of the frame 1 of the frame G, and a tongue piece 7 protruding to the outer peripheral side of the frame G at a substantially right angle. It is provided with refraction. The refracted portion is provided with a hole 9 at the center of the width, and an insertion port 13 for the support rod 11 for the stand is formed in the center of the retaining piece 5 adjacent to the hole 9, and the cylindrical back side The engaging claw 15 is formed on the. In addition, a through hole 21 is provided at the tip of the tongue piece 7 to hold the ball chain 17 as a hanging string. Further, the push pin 18 may be passed through the through hole 21. Further, a notch 20 is formed in the center of the width of the latching piece 5 so as to remove the half.
[0013]
Note that the frame 1 of the frame G is provided with a backing piece 25 of the back plate 23 projecting inwardly on the back surface where the dovetail 3 is opened, and a transparent plate 27 for stopping the work 26 is connected to the bottom of the dovetail 3. Since it is inserted into the surface piece 29, the work 26 can be taken in and out by loosening one set screw 30 of the corner coupling fitting 28 and removing the frame 1 at one end.
[0014]
As for the hanger P, the hooking piece 5 is bent and refracted with respect to the tongue piece 7, but is inverted and bent into a semicircular arc shape at the lower end portion, so that it protrudes into the dovetail 3 In this case, the tongue piece 7 is tilted so as to stand up, and as shown in FIG. 2, the tip of the curve is put in first and it is hung on the inner opening edge piece 31 of the dovetail groove 3. The engaging claw 15 is hooked on the outer opening edge piece 32. This completes the mounting as shown in FIG. It should be noted that the same operation is performed in the case of finishing. At this time, the tongue piece 7 is placed on the backing piece 25 of the frame 1 as indicated by a two-dot chain line.
[0015]
Although the engaging claw 15 protrudes from the side surface of the latching piece 5, it has a lower clearance angle slope 33 that does not resist pushing, so that the latching piece 5 is elastically deformed and below the outer opening edge piece 32. I get caught. Further, since a short steep upper clearance angle slope 34 is formed at the upper end, when the tongue piece 7 is lifted, it is detached from the opening edge piece 32 with the elastic deformation of the hooking piece 5 as shown in FIG. . In this case, when the tongue piece 7 is pushed in the proximal direction (arrow Y) to further promote the elastic deformation of the hook piece 5, it is easy to come off.
[0016]
The through-hole 21 is a so-called dharma hole composed of a large hole 21a and a small hole 21b adjacent to the distal end side, but the small hole 21b is formed by a protrusion 35 at the middle thickness portion (FIGS. 5 and 9), and the neck portion is The projections 37 and 37 from the ridge 35 are particularly narrowed. Therefore, when the ball chain 17 is hung, it is easy to pass the ball from the large hole 21a, and then it is transferred to the small hole 21b. FIG. 6 shows a state in which the frame G is hung on the wall 39 by the ball chain 17 hung on the hanging tool P in this way.
[0017]
Since the tongue piece 7 is formed narrower toward the tip and is bent at the tip, each tongue piece 7 is stabilized as a point contact with the desktop 41 when used as a pair of legs (FIG. 7). Further, in this case, the support bar 11 is inserted into the insertion port 13, but since it is narrow and tapered in the depth (FIG. 9), the attachment becomes strong so that it cannot be removed. Further, in such a stand state, the force Va supported by the support bar 11 on the back slope of the frame G acts in a direction Vb in which the engaging claw 15 is applied to the outer opening edge piece 32 of the dovetail 3 (see FIG. 3). ). And unlike the case where the tongue piece 7 is lifted, the elastic deformation which narrows the curve of the latching piece 5 is not made.
[0018]
Further, since the through hole 21 is out of the frame G, the push pin 18 is passed through the small hole 21b and stopped there, and the frame G can be hung on the wall 39 (FIG. 8).
