Description

  The present invention relates to a back plate fixing tool in a frame that is attached to a frame in order to stop a content made of, for example, a transparent plate, a work, or a back plate on the back side of the frame.

  In order to stop the contents in the frame, there is often a means of locking a latching piece called a dragonfly on the back side of the frame. In many cases, a back plate fixing tool is provided which is provided with an open concave groove and is fitted thereto by elastic deformation. As an example, a leg piece for standing on a back plate is connected to both sides of a body piece following a head piece inserted into a groove in a frame (Patent Document 1), Examples include one in which a spring is bent into a V shape so that the spring can be inserted into the concave groove, and an engaging portion that is hooked on the opening latching piece of the concave groove is formed on one piece (Patent Document 2 and Patent Document 3).

  In addition, the frame is provided with a deep and slender groove inclined from the inside of the frame, the leaf spring inserted into the groove is refracted into a "<" shape, and a through hole is provided at its end to screw the back plate (Patent Document 4) The frame is formed in a so-called C-shaped cross section where the contents hang on the front edge, and a screw screw hole is provided on one of the V-shaped leaf springs fitted between the other rear edge and the contents. A refracting part where the tip of the screw hangs is provided on a piece so that the V-shaped angle is widened by the force of the screw, and one piece is fixed to the back plate with a screw (Patent Document 5 Utility Model Application Notice) (Showa 55 No. 32538)).

  According to the conventional back plate fixture as described above, the back plate can be pressed with elasticity according to the thickness of the contents, so that it has a shape that is bulky with irregularities such as a curved shape, V shape, etc. Because it was not only suddenly noticeable, but also prone to being caught by other objects that could be dislodged, and even though a large movement is required to elastically deform the mounting However, there are inconveniences such as lack of reassurance that is far from that, and there is a limit to take the width due to the convenience of the elastic deformation operation (for example, it is not suitable for the width of the full length of the frame). .

  In view of the above circumstances, the present invention has a simple design with little unevenness when viewed from the back, although the contents can be pressed in correspondence with the thickness. Nevertheless, it is an object of the present invention to provide a back plate fixing device in a picture frame that can be firmly locked and can be attached to an arbitrary position as many times as necessary, and has an unlimited width or width. did.

  In order to solve the above-mentioned problems, the first invention is to insert a lateral groove that opens inward in the frame on the back side of each frame to be framed, and insert it into the lateral groove at the tip. It consists of a plate-like flat fixture body that holds down the back plate, a slide inner tongue piece that is always built in this fixture body so that it can be guided back and forth, and a slide operation piece of the slide inner tongue piece. The slide inner tongue piece has a hollow guide storage portion that can slide back and forth, and the guide storage portion is wide open across the front surface and both sides at the front end portion, so that the upper lip piece and the lower lip piece are thin at the front end portion. It is provided with an interval between the openings and an interval that can be inserted into the lateral groove, and the interval between the inner tongue pieces is reduced by press-fitting into the lateral groove when the slide inner tongue slides between the thin mouth openings. An obstacle Together, to constitute a back plate fixture in the frame, characterized by being configured as escape prevention function against lateral grooved work in the reduced stop.

  Since the back plate fixing tool in the frame is configured as described above, in order to use this, when the tip portion is inserted into the lateral groove of the frame, both the upper lip piece and the lower lip piece are elastically deformed to respond to the insertion. Thus, since the press-fitted state is obtained, at least a function of preventing escape due to friction acts, and the back plate fixing tool faces and holds the back plate. Similarly, it can be removed by reverse operation with elastic deformation.

  Further, the second invention is a plate for holding down the back plate by inserting the frame with a lateral groove opening inward in the frame on the back side of each frame to be framed by inserting the lateral groove into the lateral groove at the front end. It consists of a flat fixture body, a slide tongue piece that is always built in the fixture body so that it can be guided back and forth, and a slide operation piece of the slide inner tongue piece. It has a slidable hollow guide storage part, and the guide storage part is wide open across the front surface, both sides, and the bottom surface at the front end part, and has an upper lip piece at the front end part. There is provided a back plate fixing tool in a frame, which is configured such that an escape prevention function works for a lateral groove by press-fitting into the lateral groove by facing the lower surface of an upper lip piece.

  According to the above configuration, when the upper lip piece at the tip is first inserted into the horizontal groove of the frame, there is still a margin below it, but then when the slide inner tongue piece is inserted into the margin portion, a press-fit state is obtained. In addition, at least a function of preventing the escape due to friction is exerted, and the back plate fixing tool faces the back plate and is held down by being regulated by the lateral groove. When removing, it is exactly the reverse operation.

  In any of the above cases, if the escape prevention function is configured as in claim 3, it will be in a stable state that will never be removed unless the removal operation is performed. Further, it is more preferable that the lateral groove of the frame is constituted by a plurality of grooves so as to be able to cope with the thickness of the contents (claim 4).

  As described above, according to the back plate fixing tool in the frame of the present invention, although the contents can be pressed in correspondence with the thickness, the plate shape or a shape close thereto, and unevenness is seen from the back side. The design is neat and clean, and it can be set easily, but it can be firmly locked, so it can be safely removed from the exhibition, and it can be placed in any position. As many as you need, you can choose as many as you like, the size and weight of the contents, as well as the width or width is not limited, and you can get a variety of installations is there.

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

  FIGS. 1 to 9 show an embodiment according to the first aspect of the present invention. In the frame G, one back plate fixture P is provided for each frame 1,1,1,1. Alternatively, it is implemented as two or more pieces attached, and can be configured in a short piece shape but a length close to the length of the frame 1.

  The frame 1 of the frame G is formed as an extruded shape such as aluminum, so that the frame 1 is opened inward in the frame on the back side (sometimes expressed as “up”), and the lateral groove 3 of the back plate fixture P is formed. Moreover, the latching | locking part 7 of the content 5 protrudes inwardly at the front surface, and the decoration edge 7a is inserted by it. The horizontal groove 3 has inwardly protruding protrusions 8 and 9 protruding in two upper and lower stages, and a step is provided on both protrusions 8 and 9 so as to be lower near the protruding proximal end. 3, a latching inner groove 11 for the back plate fixture P is formed at the base end of the upper protruding piece 8. Further, a dent 13 is formed between the lower projecting piece 9 and the step by refracting the tip upward. This is to make it easier to insert the back plate fixture P into the diagonal Sa.

  The back plate fixture P is composed of a fixture main body 15, a slide inner tongue piece 17, and a slide operation piece 19, each of which is formed of a thin plastic in a plate shape. The tongue piece 17 has a hollow guide housing portion 21 in which the tongue piece 17 can be slid forward and backward, and the hollow portion is opened at both ends from the tip portion at the tip portion so that the upper lip piece 23 and the lower lip piece 24 are formed in a tear-like shape of the thin mouth opening 22 The lower lip piece 24 is slightly downward and the opening 22 is slightly increased toward the tip. For convenience of molding, the guide storage portion 21 is also opened at the rear end. Further, in order to attach the slide operation piece 19 to the slide inner tongue piece 17 from the upper surface, various holes are formed on the upper and lower surfaces as described later.

  The slide operation piece 19 has an upper surface formed to be uneven so that it can be easily fingered. On the lower surface, check pawls 25 and 25 are provided in left and right pairs opposed to each other at the center of the width, and are thin and round in the middle between them. A rod-like protrusion 27 is provided.

  On the other hand, the slide inner tongue piece 17 is provided with a pair of left and right coupling holes 26.26 on which the check claws 25, 25 are hooked, and a connecting hole 28 into which the rod-like protrusion 27 is fitted. The tongue piece 17 is connected on the fixture main body 15, and in order to make this possible, long holes 29, 29 through which the check claws 25, 25 pass through the fixture main body 15 above the guide storage portion 21. And a regulation slit 31 through which the rod-shaped protrusion 27 passes tightly. Further, window holes 32 and 32 are formed below the guide storage portion 21 so as to be wide in the moving range so that the toes of the check claws 25 and 25 are not hooked.

  The fixing device main body 15 will be further described. A non-returning claw-shaped hooking claw 33 having a clearance angle is erected along the end at the front end edge of the upper lip piece 23. As a peripheral edge around the periphery, the height is gradually increased backward to the bottom, and the bottom pushing portion 37 for the back plate 5a is formed with a thick wall. Further, a through hole 41 of a screw 39 that is screwed into the back plate 5a is provided at the center of the bottom portion, and a thick wall portion that is in contact with the back plate 5a is provided around the bottom surface thereof.

  When the back plate fixture P is assembled as described above, when it is used, the back side of the frame G faces upward (FIG. 1), and the horizontal groove of the frame 1 from above the back plate 5a of the contents 5 is used. 3 (S direction). However, at that time, if the tip of the lower lip piece 24 is slanted downward (Sa direction) while being hung on the lip of the lower protruding piece 9, the mouth opening 22 is contracted by elastic deformation, so that the latching claw 33 is in the upper stage. Since the upper lip piece 23 and the lower lip piece 24 are elastically deformed, it is easy to obtain a clue for insertion, and when it is pushed in gradually gradually, the latching claw 33 is latched by elasticity. It falls into the inner groove 11 and is hooked on it.

  FIG. 3 shows a point in time when the insertion is completed, and the upper lip piece 23 and the lower lip piece 24 are in full pressure contact with the upper protruding piece 8 and the lower protruding piece 9 due to the remaining elasticity, respectively. Since the main body 15 is held horizontally, the bottom pushing portion 37 pushes down the back plate 5a by the horizontal holding force. Although it will be in the state of a back board hold | maintenance now, it decided to fix after securing this state temporarily temporarily.

  FIG. 4 shows a fixed state. First, the slide operation piece 19 is pushed with a finger, and the slide inner tongue piece 17 is inserted between the upper lip piece 23 and the lower lip piece 24. If it does so, since elastic deformation will be blocked | prevented by the slide inner tongue piece 17 by the front-end | tip part, it will be in the temporary fix | stop state by which the latching claw 33 never falls out from the latching inner groove | channel 11. Further, the screw 39 is screwed into the back plate 5a through the hole 41 to secure the fixing. In this state, the screw head serves as a stopper for stopping the return of the slide operation piece 19.

  When the screws are fastened, the frames 1 and 1 facing each other are connected in a non-expandable manner, particularly in a large frame, due to the connection between the latching inner groove 11 and the latching claw 33, so that the flexure is prevented. However, the screw 39 may not be used particularly in a small frame, and the slide inner piece 17 may be returned together with the slide operation piece 19 until the screw is fixed, and it is necessary to prevent this. From this point of view, a lock device for preventing return is constituted by the rod-like protrusion 27 and its regulating slit 31. In this regard, the restriction slit 31 is formed in a wide area where the rod-shaped protrusion 27 is slowly accommodated at the start point portion 31a, and is formed in a circular shape which is slightly larger than the rod-shaped protrusion 27 at the end point portion 31c, and the sliding portion 31b therebetween is tightly fitted. Therefore, when the rod-like protrusion 27 is at the end point portion 31c, it is in a semi-locked state.

  With respect to the escape prevention function for preventing the distal end portion of the fixture body 15 from coming out of the lateral groove 3, in the above embodiment, the latching inner groove 11 is provided in the lateral groove 3, and the distal end of the fixture body 15 is provided. Although the latching claw 33 is provided in a projecting manner, the present invention is not necessarily limited to this, and if the lateral groove 3 is formed deeply with respect to the thickness of the distal end portion of the fixture main body 15, only the friction caused by the elasticity can be obtained. Stability that can prevent escape is obtained. Further, in order to particularly increase the friction and catching, at least one of the inner surface of the lateral groove 3 and the surface of the fixture main body 15 to be joined to it is formed as a high-friction surface, or both of them are fine uneven surfaces such as corrugations. It is also possible to take a means to form. Moreover, in order to enable elastic deformation, the fixture main body 15 can be formed of a spring material.

  The back plate fixture P can be configured to be horizontally long or long along the inner periphery of the frame G, but in this case, a plurality of slide inner tongue pieces 17, 17,. Can be built in parallel. Further, the slide operation piece 19 can be integrally formed with the slide inner tongue piece 17.

  FIG. 10 shows an embodiment of the second invention described in claim 2, and is different from the above embodiment only in that the lower lip piece 24 is not provided, and the other points are basically the same. Since they are the same, the same reference numerals are given and description thereof is omitted. Therefore, in order to attach this to the horizontal groove 3, the upper lip piece 23 is inserted into it, and when the slide operation piece 19 is pushed to insert the slide inner tongue piece 17, it acts as a wedge and comes out of the horizontal groove 3. At the same time, a fixed stability for holding the back plate 5a is obtained. The escape prevention function regarding the presence or absence of the latching inner groove 11 and the latching claw 33 is almost the same as the above-described point.

  In order to be able to cope with the thickness of the contents, it is preferable to form the lateral groove 3 of the frame 1 in the above embodiment into a plurality of grooves.
