Description

[0001]
The present invention relates to a frame that can stop a back plate against which a work is applied, a Western canvas, a wooden frame of a Japanese painting, etc., by operating a lock slider.
[0002]
[Prior art]
The method of fixing the back plate in the frame is generally based on a latching piece called a register mark pinned to the back side. In addition, there are cases where means for fastening with a screw from the side surface or the back surface of the frame is used. In addition, when using a so-called register mark, there is a problem that the back plate tends to bend particularly if it is a large frame, and if the back plate is too thick or insufficient, it cannot be dealt with. Japanese Patent Laid-Open No. 11-216051 proposes to solve the problem of the excessive or insufficient thickness of the back plate.
[0003]
The frame described in the publication includes a slider with a protrusion that can be moved along a side of the back plate at a predetermined distance, and an engagement groove for the protrusion is provided on the inside of the frame. Since the engaging groove is formed to be inclined, when the slider is moved in one direction, the protrusion rises along the inclination of the engaging groove, so that the back plate is independent of the thickness. Pressed to the front side. In addition, in the same frame, since it is necessary to insert and remove the back plate, the frame is provided with an entrance / exit in which an engagement groove opens at one end, and the projection can be passed through the entrance / exit so that the back plate can be stored and taken out. Yes. In this publication, the frame body and the back plate are each described as a frame integrally formed of plastic.
[0004]
By the way, the back plate to be stored in the frame, especially panels such as canvas and wooden frame are generally made of wood, and the back plate is particularly thin. However, the slider should be slidably provided on such a panel. Is not productive. In addition, if a structure that stops the slider from being moved inadvertently is adopted, the structure becomes more complicated. In order to stop this movement, the above publication has a structure in which the engaging groove and the projection are engaged with each other by a toothed shape, so that it is not suitable for implementation on a general frame having an extruded profile as a frame. It was. In addition, since the structure is complicated, it is not easy to adopt a replacement method with another panel (replacement is common and often necessary for canvases and wooden frames).
[0005]
[Problems to be solved by the invention]
In view of the above circumstances, the present invention is easy to mount and remove the panel by operating the slider built in the frame, has a simple structure, and is suitable for a frame of an extruded shape member such as aluminum. The purpose of the present invention is to provide a frame that not only allows easy replacement of the panel but also prevents inadvertent movement of the slider .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a frame by a vertical and horizontal frame made of an extruded shape member having an inward shape having a side wall as a base and having a dovetail groove having a shape in which a back side inner groove and a front side inner groove face each other. Frame frame body, a panel detachably fitted inside the frame, and one or more lock sliders for preventing panel detachment built into the frame by insertion into the dovetail groove. The back piece that constitutes the inner groove on the back side is removed, and a notch that is opened and closed by a lock slider is provided, and the panel is provided with a latching protrusion that can be put in and out of the opened notch and held down by the lock slider In addition, the lock slider is configured with a picture frame characterized by protruding finger hooks as protrusions that restrict the slide range by alternately hooking the edges of both ends of the notch. .
[0007]
[Operation]
According to the above configuration, when the panel is put in, the locking slider is opened, the locking protrusion of the panel is dropped into the dovetail from the notch, and the locking protrusion is held down by closing the lock slider. . Thus, the panel is not only prevented from escaping but also prevented from being bent or displaced. When removing the panel, open the locking slider to escape the latching protrusion. The opening and closing of the lock slider can be easily performed by a finger hooking operation as a protruding portion that regulates the slide range. Then, by forming the finger hook so as to be flush with or below the back surface of the frame (Claim 4), it is possible to prevent the finger hook from moving in contact with other objects .
[0008]
In addition, the lock slider is built into the frame as a whole, and the finger rest is placed in the notch so that it is flush with or below the back of the frame. The movement is prevented and the lock slider securely holds the latching projection so that the panel is safely held so that it does not fall off.

The frame 5 is provided with a notch 6 that is opened and closed by the lock slider 3, the panel 2 is provided with a latching protrusion 9 that can pass through the opened notch 6, and the lock slider A positioning and fixing device 10 that stops both opening and closing of 3 is provided.
[0016]
Each frame 5 has a dovetail groove 7 having a side wall as a base, and a hollow front piece 13 having a semicircular cross section projecting from the front end of the side wall, and opposed to a back piece 15 having an L-shaped cross section. By projecting the strip 17, the dovetail groove 7 is formed in a shallow bottom, and due to its shape, the dovetail groove 7 has inner grooves 8a and 8b on both the back side and the front side. Then, the notch 6 is formed by partially removing the back piece 15. Further, a latching hole 16 is formed by a punch as a reference for the positioning and fixing device 10 on the bottom surface of the back-side inner groove 8a.
[0017]
A frame of the frame body 1 is formed by inserting an L-shaped connecting metal fitting 18 into the dovetail groove 7. The lock slider 3 is pushed into the dovetail groove 7 from the inner surface of the frame 5 and incorporated therein. Built-in.
[0102]
The panel 2 is a wooden frame of a Japanese painting in which a plate material 21 is attached to the front side of the frame of the vertical and horizontal crosspiece 19, and the head is large in a frame shape on the side of the crosspiece 19 at a position corresponding to the notch 6 of the frame 5. A hook is screwed in, and the head of the hook is the above-described hooking protrusion 9. The latching protrusion 9 is sized to be pressed into the front side inner groove 8b of the dovetail groove 7 by the lock slider 3, thereby preventing the panel 2 from being displaced and the frame from being bent. Reference numeral 40 denotes a transparent acrylic plate.
[0019]
The lock slider 3 is integrally formed of plastic and has a rectangular cross-sectional shape that is slidably engaged with the inner groove 8a on the back side of the dovetail groove 7. The spring legs 21 and 21 that are pressed by the front inner groove 8b of the dovetail groove 7 are projected by the elasticity of the rod, and a rod-like bottom support 23 is suspended in front of the spring leg 21 at the front end. The front trunk-like portion serves as a presser portion 25 of the latching protrusion 9. A pressing guide port 27 of the latching protrusion 9 is formed on the slope at the tip. Further, a finger hook 28 as a projecting portion made of a pair of projections is projected from the tip of the upper surface of the trunk-like portion, and a pair of front and rear projections as one element of the positioning and fixing device 10 of the lock slider 3 are projected on the upper surface of the rear half. 31, 31 are formed.
