Description

[Detailed Description of the Invention] This invention relates to a back plate holder for a picture frame whose frame frame is made of an extruded section made of light metal.

A rotating claw called a so-called dragonfly is sometimes used to hang the back plate of a picture frame, but in this case, the position where the back plate is held is limited to approximately the same plane as the back side of the frame rib, so the back plate is It was not possible to use a picture frame that was inserted deep into the back side of the frame bone, as it was functionally useless.

Therefore, in a picture frame with such a deep backboard position,
A latching protrusion that protrudes toward the inside of the frame is provided on the back side of the frame rib, and a latching device made of a bent leaf spring is interposed between the latching protrusion and the back plate, so that the back plate can be moved by the elastic force of the leaf spring. However, since the frame ribs are provided with hanging protrusions, the structure becomes complicated, making it unsuitable for weight reduction, and the hanging protrusions get in the way, making it difficult to hold the work or the back plate. It is troublesome to attach and detach the hook, and furthermore, when attaching the hook, it is necessary to press it onto the back plate and to slide it with dexterity.

This invention solves the above-mentioned shortcomings all at once; there is no need to protrude a hanging protrusion from the frame frame in order to attach a hanging device made of a leaf spring; The purpose is to make it possible to attach it to any location with simple operation.

FIGS. 1 to 8 show an embodiment of this invention. First, in the same figure, a picture frame G using a hanging tool P will be explained. The frame frame 1 is
It is made of an extruded aluminum alloy, and has a substantially L-shaped cross section with a surface wall 3 protruding from the front end of the side wall 2, and the side wall 2 has a connecting groove 4 that opens to the inner surface and a deep groove that opens to the back end surface. 5 is provided. Of these, the connecting groove 4 is for inserting an L-shaped connecting fitting to connect the vertical and horizontal frame frames 1, 1, but the deep groove 5 is for attaching the hook P, and is deeper than the width. The inner surfaces 6, 6 on both sides are formed into vertical surfaces without catching. In the figure, 7 is the back plate, 8 is the plate glass, 9 is the mat, and 10 is the work.

The latching device P is entirely composed of a single metal band-shaped leaf spring, and has a body portion 12 bent at an obtuse angle in a dogleg shape with respect to the leg portions 11.
A foot portion 13 that presses the back plate 7 of the picture frame G onto the tip of the foot portion 13.
is provided, and the foot portion 13 is bent backward. Further, a head 14 that is fitted into the deep groove 5 of the picture frame G and is taller than the deep groove 5 is provided at the tip of the body 12. The width M of the deep groove 5 is larger than the width N of the deep groove 5. Furthermore, a circular hole 15 is provided in the center of the body 12 to hang a nail or string.

In the above configuration, when attaching the hanging device P to the picture frame G, first, as shown in FIGS.
3 to the back plate 7, and the head 14 faces the deep groove 5, but the opposite width M corresponds to the width N of the deep groove 5.
Since the head 14 will not fit into the deep groove 5 if the head 14 is moved lightly as it is, as shown in Fig. 3, when the waist 16 is pressed, the waist stretches and the angle of the torso 12 changes to the supine direction. , tip piece 1 of head 14
When the downward inclination angle of the head 7 becomes steep and the width m of the head 14 becomes equal to the width N of the deep groove 5 due to the angle, the head 14 is pushed into the deep groove 5. Then, when you remove your finger from the waist 16, the restoring force of the spring will cause
As shown in FIGS. 4 and 6, the head 14 comes into pressure contact with both the inner and outer walls 18 and 19 constituting the deep groove 5, and the tip piece 17 of the head 14 presses against the inner wall 18 at the inner pressure contact part 20. A rotational force is applied to the hook P to press the back plate 7 using the outer press-contact portion 21 as a fulcrum, and the head 14 is pushed against the inner surfaces 6, 6 on both sides of the deep groove 5 due to the reaction force that presses the back plate 7. This creates a frictional force or a catch that prevents the material from coming out of the deep groove 5 easily.

Next, when removing the hook P, simply
If only the head 14 is lifted up, the pressing force of the head 14 against the inner and outer walls 18 and 19 of the deep groove will be increased, so that the head 14 will not come off. This means that the stability of the attached state of the hook P is ensured, but it is not so difficult to remove it.As shown in FIG. When a force is applied to rotate the hook P by lifting it slightly and twisting it in the other side direction R, one end of the head 14 becomes circular because the outer surface of the head 14 is a circular curved surface. Since the hook P rides on the outer wall 19 of the deep groove 5 while rubbing against the curved surface, it is extremely easy to remove the hook P unless you make a mistake in this operation. In order to ensure smooth riding, the edge 24 of the tip piece 17 of the head 14 is formed into an arc shape as shown in FIG.

9 and 10 show another embodiment, in which the inner wall 18 of the deep groove 5 of the frame 1 is lowered to a lower outer wall 19.
By forming a slope 25 that is lower toward the deep groove 5 at the upper end of the inner wall 18, and forming the head 14 of the hook P in a hook-shaped cross section, the width M thereof is made larger than the width N of the deep groove. I've made it bigger. In this case, the tip piece 17 of the head 14 can be inserted into the deep groove 5 by sliding it on the slope 25 while pressing the waist part 16. And, as in the above example, two pressure welding parts 20,
The back plate 7 is pressed against the hook P in a relative relationship of 21, and the details will be given the same reference numerals and a detailed explanation will be omitted.

Next, FIGS. 11 and 12 show still another embodiment, in which the thickness of the latching tool P as a plate spring is formed large, and the tip piece 17 of the head 14 is formed into a deep groove 5.
The thickness is such that it fits tightly. In this case, the hook P is suitable for being molded from synthetic resin, the tips of the legs 11 are rounded so as not to catch on the back plate 7, and no feet are provided.

As explained above, the hanging device of this invention can be attached by an extremely simple operation of pressing the waist portion 16 toward the back plate 7 while placing the head against the deep groove of the frame bone of the picture frame.

That is, since the legs, torso, and head of the hanging device of the present invention are all integrally formed from a single band-shaped leaf spring, the elastic force ( The restoring force) in the head part of the hanging tool expands the bending part of the head in the front-back direction and has a latching effect on the deep groove of the frame bone, and on the other hand, in the leg part 11 of the hanging tool, the back plate 7 At the same time, a pressing action is caused. In addition, in the head 14, the extension of the waist part 16 causes the acute-angled head bending part to expand using the upper end surface of the inner wall 18 of the frame bone deep groove as a fulcrum, and the elastic compressive force (restoring force) after the expansion is applied to the frame bone. Since it abuts against the inner surface of the deep groove, the compressive force of this head (pressure force against the deep groove) provides a firm latching.

Moreover, since the frame bone is made of light metal, the deep grooves of the frame bone can withstand the severe digging of the head of the latching tool, and the bonding force with the frame bone is extremely strong, resulting in a stable installation condition. , back plate, etc. can be safely held.

Further, since the frame rib is a pressed member and has deep grooves along its entire length, there are no limitations on the mounting location.

In addition, since the hanging device of the present invention is made of a single band-shaped leaf spring, it is strong overall. In particular, the head, which presses and latches into the deep groove of the frame bone against the upward force from the back plate and the restoring force of the waist, is supported in a linear or planar manner in the width direction of the band-shaped leaf spring. Therefore, it is possible to provide a hanging tool that is stable in terms of strength and durable for repeated use.

Furthermore, there is no need to provide a hanging protrusion on the frame rib of the picture frame for hooking the hanging tool, and a simple deep groove may be provided, but the frame rib does not have a particularly complicated cross-sectional structure. It also has a remarkable effect in promoting the simplification and weight reduction of picture frames.
