DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backing apparatus for a work in a picture frame in which a position for holding a storage body such as a campus can be appropriately adjusted according to its thickness.

[0002]

2. Description of the Related Art In a picture frame, a projecting portion on which a storage body (often a sheet glass) is hung is formed at the front end of each frame that forms the picture frame. Is held. There are various types of backing devices, for example, a dragonfly blade type that is rotatably stopped on the back of the frame is often used, but this cannot respond to the thickness of the storage body, so the position to stop is changed according to the thickness Many proposals have been made.

As a conventional backing device for a work in a frame of this kind, there is a screw adjustment type (Japanese Utility Model Publication No. 59-32354) in which a backing piece for stopping a storage body is moved up and down by a screw mechanism. A slope groove is formed in a cross section of a frame of a frame, and a height of the back piece is adjusted by sliding a body having a back piece on the slope (Japanese Patent Laid-Open No. 8-415). Publication) and the like.

[0004]

Among the conventional backing devices for works in picture frames as described above, in the case of the screw adjustment type, the backing piece can be freely adjusted by feeding the screw. Since turning work takes time, there is a problem in workability when replacing works.

In the case of using a slope, it is necessary to form the frame into a special section having a slope groove and lacking versatility, and it is inevitable that the cost is increased in this respect. In addition, height adjustment using a slope is slightly more difficult than simple vertical adjustment, and the height adjustment involves a change in the planar position of the backing piece. There was also a problem that it could be stable.

The present invention has been made in view of the above-described circumstances,
Regardless of the thickness of the storage body, it can be stopped very easily and can be stably held as it is, and furthermore, the backing of the work in the picture frame whose planar position is constant regardless of the height of the backing piece The aim was to provide a device.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a base which is mounted vertically inside a frame constituting a picture frame in a direction of adjusting a backing position, and a base for adjusting the base. It consists of a backing piece that can be slid vertically and a push button that is integral with the backing piece and protrudes from one side and is urged in the protruding direction. A claw plate which is continuously arranged is formed, and the push button is provided with a protruding claw which is applied to the check claw by the urging force, and the check claw is upward on the back side of the picture frame and downward at the angle of attack. A backing device for a work in a picture frame characterized by being formed at a clearance angle was constructed.

In addition, a concave fingertip is formed on the protruding surface of the push button, and another fingertip is formed on the backing piece symmetrically to the fingertip on the opposite side. It is more effective to achieve the purpose if the piece and the push button are configured to be able to be gripped integrally.

Further, a foot piece bent forward is formed at the lower end of the base, and a mounting claw having a curved cross section is formed at the back of the upper end, and the foot piece is inserted into a paragraph retaining groove provided in the frame. When the base is raised by applying a force to the frame, the mounting claw can be hooked on the upward locking projection provided on the frame with a downward force caused by the elastic deformation of the foot piece, so that the frame can be easily mounted.

[0010]

[Work] Since the backing device for works in the picture frame is configured as described above, when using it, the base must be mounted on the frame in advance, and the storage of the works etc. must be placed in the picture frame before each base. Combined with the backing piece, so that the storage body is pressed from the back side. At this time, since the back stopper piece is abutted against the storage body and is locked by the non-return at a position where the back stop piece is stopped, it can be held down in accordance with the thickness of the storage body in each stage of the non-return claw of the claw plate.

When removing the storage body for replacement of a work or the like, the locked state is released by pushing a push button, and the backing piece is lifted and removed. As described above, when the backing pieces are combined or subsequently pressed down, if the push button is pressed, such operation is further smoothly and easily performed.

[0012]

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

The drawing shows an embodiment, and a backing device P for a work in a frame is provided at a position suitable for stopping a storage body W of a work or the like on each frame 1, 1, 1, 1 of the frame. A base 5 directly fixed to the frame 1, a backing piece 6 slidably mounted on the base 5 and a push button 7 for locking and releasing the sliding position of the backing piece 6. It consists of a combination, each molded from plastic. For convenience of explanation, the front side of the frame is described as “bottom” and the inside of the frame is described as “front” mainly in FIG.

Each frame 1 is made of an extruded aluminum material, and is provided with a projection 2 for stopping the storage body W at a lower end as a front side.
The dovetail groove 3 for inserting the connecting metal fitting is formed, and the apparatus P is mounted by applying the base 5 to the opening side surface of the dovetail groove 3. For this attachment, a paragraph retaining groove 9 is formed in front of the opening side surface, and an upward retaining protruding piece 11 is formed at the upper end. However, this structure is very small as a whole, and even if it has such a structure, there is not much difference from a general frame, and there is no lack of versatility.

The base 5 is attached vertically to the inside of the frame 1. A T-shaped guide rail 13 is provided on one side to slide the backing piece 6 in the engaged state. A ridge 15 is formed shifted. The displacement of the ridge 15 is to prevent an error in inserting the backing piece 6 upside down. On the other side of the base 5, a nail plate 17 bent forward at a right angle is provided, and a large number of non-return claws 18, 18,...

In use, first, the base 5 is mounted on the frame 1, and the mounting structure is such that the above-mentioned paragraph locking groove 9 of the frame 1 has a locking edge 10 at the front end. On the other hand, at the lower end of the base 5, a foot piece 19 hanging on the hooking edge 10 is bent and formed, and on the back surface of the upper end, a mounting claw 21 having a curved cross-section hanging on the hooking projection 11 is formed. did.

Therefore, as shown in FIG.
When the base 5 is raised after the hook 9 is applied, the foot piece 19 is hooked on the latching lip 10, and the foot piece 19 is elastically deformed with the lower end of the base 5 as a fulcrum. When the mounting claw 21 is hung on the hooking projection 11, the base piece 5 is pushed down and held by the catch of the foot piece 19, so that the mounting claw 21 never comes off unless a removing operation is performed, and a stable mounting state. Is held.

The backing piece 6 is in the form of a thick hollow plate, has a hanging wall 22 formed at the rear end thereof, and is provided with a dovetail-shaped fitting slider portion 23 fitted on the guide rail 13 of the base 5. , And moves up and down along the guide rail 13 by engagement with the guide rail. The backing piece 6 is provided with a through hole 14 for a screw 12 for stopping the storage body W, and a tongue-shaped elastic inclined piece 16 for elastically pressing the storage body W is provided on the back surface (see FIG. 4). 3 and 4). In addition, since the holding of the storage body W is ensured, screwing is not necessarily required.

The push button 7 is urged toward one side of the backing piece 6 so as to protrude therefrom. At the rear end of the push button 7, there is provided a projection claw 25 which engages with the check claw 18 of the claw plate 17. In order to make the projection claw 25 elastic, it is formed to hang down in an L-shaped leg shape. However, the backing piece 6 is provided with the hanging wall 22 so that the backing piece 6 is not excessively deformed by the reaction received from the storage body W.
Is formed at the end of (FIG. 3).

In order to urge the push button 7 in the projecting direction,
While the backing piece 6 is formed hollow, the push button 7 is provided with an insertion piece 27 that fits therein (FIGS. 2 and 6).
A spring 31 having an arcuate shape is formed at the tip of the spring, and claw portions 31 are provided on both sides against the elasticity of the spring 29. Further, on both sides inside the hollow of the backing piece 6, there are provided step portions 33, 33 on which the claw portions 31, 31 are engaged.

The urging means of the push button 7 is as follows.
The present invention is not limited to this. For example, a spring may be formed inside the backing piece 6, and a separate spring may be provided. Further, the push button 7 may be formed integrally with the backing piece 6, and the urging force may be obtained by elastic deformation therebetween.

The check pawl 18 of the pawl plate 17 is shown in FIGS.
Since the clearance angle is downward as shown in FIG.
Can be easily combined, and the storage body W can be pressed and stopped at an arbitrary position corresponding to the thickness thereof while being pressed down (see the two-dot chain line in FIGS. 3 and 4). Conversely, when pulling up to remove the backing piece 6,
Pushing the push button 7 removes the projection claw 25 from the check claw 18 so that the operation can be easily performed. When lowering, it is not always necessary to press the push button 7, but if it is pressed, it can be pressed down smoothly.

To protrude the push button 7 easily, a finger rest 35 which is curved and depressed is formed on the protruding front end face, and a finger rest 37 is also formed on the opposite side of the backing piece 6 correspondingly. . Therefore, one finger pad 35 is put on the thumb and the other finger pad 37 is put on it.
The finger can be moved up and down while pressing the push button 7 by touching the index finger or the middle finger with the finger.
