[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table support leg of a picture frame to be supported behind the picture frame so as to be inclined backward on the table.

[0002]

2. Description of the Related Art A picture frame is generally placed on a wall. However, a picture frame may be placed upright on a table, in which case supporting legs are used for supporting the picture frame.
Japanese Utility Model Publication No. Sho 62-540 is an example of this type of support leg. This is a backing plate supporting type, but a protruding type in which the tip is hooked in a dovetail groove of a lower frame has also been developed.

[0003] As can be seen in the publication, the support leg of the back plate support type has a mounting portion to the back plate of the picture frame and a leg leg serving as a support, which are integrally formed so as to be swingable by a hinge portion. In addition, it is necessary to provide a mounting hole for mounting to the back plate, and it is not only troublesome to mount, for example, caulking or screwing means is required, but also its position is limited, Then, such a disadvantage is solved.

[0004]

However, according to the protruding support legs, the dovetail groove of the frame is supported at two points so as not to fall down, so it is necessary to have two support points.
Since these two points must be formed by a vertical gap and be capable of being inserted, in particular,
The tip has a very complicated bent shape, and the insertion operation is also troublesome work to be pushed up and down, and it is attached in an easy engagement state that comes out of the dovetail groove, so that the frame is moved by lifting etc. There is a problem that it is inevitable in terms of structure that it easily falls off.

[0005] Regarding the complexity of the structure, both the back-plate support type and the face-down type are inevitably inconvenient to transport and store because they have a bulky shape. There was also a problem of being unsightly.

[0006] In view of the above situation,
It is a prone shape that hooks into the dovetail groove of the lower frame of the picture frame,
An object of the present invention is to provide a frame-shaped tabletop support leg which can be easily attached and detached, has a stable attached state in which it never falls off, and has a compact form without being bulky.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention proposes a method in which a pair of upper and lower legs are pivoted at a base end so that they can be opened and closed by scissors. Then, the tips of the upper leg and the lower leg are formed to a thickness that can be inserted into the dovetail groove of the frame of the frame by itself open, but cannot be inserted in the superposition, and are attached to both ends thereof. Is formed such that a locking groove is formed on the opening ridge of the dovetail groove so that the locking groove cannot be escaped when overlapping, and at least one of the both locking grooves can be locked on the opening ridge while closing for the overlapping. It is characterized by having done.

[0008]

According to the above construction, in the opened state, both ends of the upper leg and the lower leg can be inserted into the dovetail groove of the frame.
By inserting the dovetail into the dovetail in an open state and closing the dovetail, the two dovetails conform to the state of being hooked on the opening ridge of the dovetail.

Therefore, it is not necessary to make the upper leg and the lower leg bulky and bent, and the structure is simple. When the upper leg and the lower leg are closed, the upper leg and the lower leg are overlapped to form a very compact form. Become.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings.

The table-top support leg S of the frame is a face-down type to be hung on the lower frame F of the frame G, and is composed of a combination of two upper legs 1 and lower legs 3, each of which is easily elastically deformed. It is molded from plastic and is pivoted at the base end. However, integral molding is also possible.

The upper leg 1 and the lower leg 3 have substantially the same scale shape, and shaft attachment portions 5 and 7 are formed at the base ends in a disk shape. Both end portions have thicknesses a and b smaller than the opening width W so that they can be inserted alone into the dovetail groove 4 of the frame F, but cannot be inserted with the combined thickness. Then, a hooking groove 6 on which the upper opening ridge 10 of the dovetail groove 4 is hooked is formed on the upper surface of the tip of the upper leg 1 so that the lower leg 3 cannot be escaped.
Are formed at the tip end portions thereof with engaging grooves 8 on which the lower opening ridges 12 are engaged.

The shaft attachment portions 5 and 7 are configured to rotate by rubbing about the center thereof. A shaft 9 projects from the back surface of the upper leg 1, and the shaft 9 fits into the lower leg 3. A shaft hole 11 is provided. In order to prevent the shaft 9 from coming off, hooking pieces 13, 13 projecting from the tip of the shaft 9 in a direction perpendicular to the longitudinal direction of the upper leg 1 are provided. In the hole 11, notches 15, 15 through which the hooking pieces 13, 13 pass are formed in the longitudinal direction of the lower leg 3.

In order to combine the upper leg 1 and the lower leg 3 based on the directionality of the hook pieces 13 and the notches 15, the shaft 9 is inserted into the shaft hole 11 at right angles to each other. Then, the upper leg 1 and the lower leg 3 are overlapped in the same direction.
Then, the hooks 13 and 13 of the shaft 9 and the notches 15 and 15 of the shaft hole 11 have different phases, so that the shaft 9 cannot escape. Since the upper leg 1 and the lower leg 3 are almost in the same direction in both cases of opening and closing in use, the combination is stably held.

On the back surface of the shaft attachment portion 7 of the lower leg 3, in order to prevent the engaging pieces 13, 13 of the shaft 9 from projecting, the engaging pieces 13, 13 rotate around the peripheral edge of the shaft hole 11. A recess 17 is provided. Further, on the back surface of the shaft attaching portion 7, a rough surface 19 is formed widely in order to increase the frictional resistance on the desktop.

The upper leg 1 and the lower leg 3 are opened and closed face to face like the scissors around the shaft 9 in this way. The retaining groove 8 of the lower leg 3 is formed in an arc shape centered on the shaft 9 and is formed to be considerably wider than the thickness of the lower opening ridge 12 of the dovetail groove 4. However, the retaining groove 6 of the upper leg 1 is formed to be slightly wider and straighter than the thickness of the upper opening ridge 10.

Since the locking grooves 6, 8 are formed as described above, the upper leg 1 is hooked at right angles to the frame F,
The lower leg 3 has the flexibility of hanging at different angles. Therefore, in this embodiment, the following attachment procedure is performed.

As shown in FIG. 1, when the upper leg 1 and the lower leg 3 are opened as if the scissors are opened, first, the upper leg 1 is opened.
Of the lower leg 3 is hooked on the dovetail groove 4 (arrows P ₁ , P ₂ ) while the hook groove 6 is hooked on the upper opening ridge 10. Upper leg 1 and lower leg 3
Is closed (arrow P ₃ ), and the upper leg 1 and the lower leg 3 are brought into a single plate shape (FIG. 2).

At this time, the same closing force is applied to the upper leg 1 and the lower leg 3 by the operation of one hand, but since the upper leg 1 does not move at a right angle, only the lower leg 3 performs the closing operation. The tip is pushed into the dovetail groove 4. At the time of being squeezed, the locking groove 8 of the lower leg 3 is caught by the lower opening ridge 12 by being elastically deformed as a whole or inclined somewhat to the side. Then, by sliding while engaging with the ridge 12, the lower leg 3 overlaps the insertion position of the upper leg 1 to complete the mounting (FIG. 2).

Therefore, the insertion position of the upper leg 1 is the mounting position, and the mounting position is easily determined. In order to keep the lower leg 3 as horizontal as possible and to easily insert it into the dovetail groove 4, the upper leg 1 is reduced in thickness toward the base end so that the upper leg 1 is elastically deformed. is there.

Unlike the above-described embodiment, if both the retaining grooves 6, 8 are formed in the same arc shape slidable with respect to the opening ridges 10, 12, the upper leg 1 and the lower leg 3 are formed. Are closed at the same angle with respect to the frame F, so that they are simultaneously hung on the opening ridges 10, 12, so that the center of the opening is the mounting position.

In any case, since the upper leg 1 and the lower leg 3 cannot be opened in the mounted state, even if the frame G is moved violently, it never falls off or hangs down. Removal is possible only by opening, which can also be easily done with one hand.

As for the shaft attachment, as described above, the upper leg 1
In addition to the case where the shaft 9 is integrally formed, there are means such as screwing and caulking. Further, a method of forming thin hinge portions at both base ends by integrally molding the upper leg 1 and the lower leg 3 can also be mentioned.

[0024]

As described above, according to the present invention, the following excellent effects can be obtained.

1) Opening the upper leg and the lower leg and inserting the tips of the legs into the dovetail groove of the frame, the mounting is completed simply by closing, and conversely, the mounting can be removed by simply opening the supporting leg. Installation and removal are very simple, and the workability is good.

2) In the mounted state, the upper and lower hooking grooves are caught by the ridges of the dovetail groove, and the thickness of the tip is larger than the opening width. Nevertheless, it does not come off or hang down, and maintains a stable mounting state.

3) Since it is a two-piece compact form of the upper leg and the lower leg, compared to the case of a complicatedly bent shape, not only the appearance is good but also a large number of It is advantageous for transportation and storage, and it is easy to format and package with a frame.
