Description

  The present invention relates to a presser that is stopped by a plastic elasticity on the back side so that contents such as a back plate and a campus are not escaped in a frame whose frame is an extruded shape member.

  Conventionally, as a content presser in a frame, a so-called registration mark called a dragonfly is rotatably attached to the back side of a frame, and a back plate or the like is fixed so that it cannot be escaped at its rotational position. In this case, since the thickness of the contents cannot be accommodated and there are disadvantages such as the fact that it is not easy to attach and detach the latching piece, the applicant first determines the thickness of the contents by the elasticity of the elastically deforming presser piece. In addition, there has been proposed a content holder in a frame that can be attached and detached to provide a dovetail groove in a frame (Patent Document 1).

As shown in FIG. 16, the content presser Pa includes a bifurcated attachment base body 54 that can be inserted into the dovetail groove 52 at the frame opening of the dovetail groove 52 on the back surface of the frame 50, and an upper end waist portion 56 thereof. Are formed in the inner surface of both sides of the dovetail groove 52, and check claws 60, 60 are formed on both inner surfaces of the dovetail groove 52. 62 and 62 were formed with reverse leg portions 64 and 64 that were not able to escape from the check pawls 60 and 60, respectively.
Japanese Patent No. 2866304

  According to the content holder in the conventional frame as described above, when the both legs 62, 62 of the base body 54 are inserted into the dovetail groove 52 of the frame 50, the space between the legs 62, 62 is once narrowed, so 64 and 64 are hooked on the check pawls 60 and 60, and the attachment is difficult due to the total amount of elastic deformation of both legs 62 and 62 due to resistance in insertion.

  In the mounted state, the contents can be pressed and held by the elasticity of the slide presser piece 58, and when removing the work, the presser at the inner tip can be conveniently released by pulling the slide presser piece outward. In addition, since both reverse feet 64 and 64 are hooked on the check pawls 60 and 60 due to the elasticity of the crotch opening and hold each other's hooks, stability that never comes off unless special operation is performed. Have On the other hand, however, there is a disadvantage that the operation of the slide retainer becomes difficult for some reason, for example, for defective replacement or when it is desired to remove the excessively attached excessively.

  In view of the actual situation as described above, the present invention is easy to operate because the resistance to be inserted into the mounting groove as the dovetail is halved when it is attached to the frame of the frame, and the contents are securely and securely pressed. An object of the present invention is to provide a content presser in a frame that can be stopped and that can be easily removed by the reverse operation because the reverse foot can be removed from the check claw by the principle of lever.

  In order to solve the above-mentioned problems, the present invention provides an attachment groove for the content presser in the rear opening or the inner opening of the frame in the rear part of the frame to be framed. In the frame where the check claw protrudes from the inner surface of the side groove wall, each is composed of a combination of a base body made of plastic and a slide holding piece of contents, and the base body has a waist portion at a position corresponding to the back surface of the frame In addition, the main and auxiliary legs, which can be pushed in while being elastically deformed into the mounting groove, protrude from the waist directly or through a detour piece into a fork, and the waist is formed with a lateral slide groove that extends inward and outward, The slide pressing piece is an elastically deformable plate that is held in the slide groove of the base body, and the main leg of the main and sub-legs of the base body may be unable to escape from the check pawl of the mounting groove. Reverse And the other auxiliary leg is formed in the mounting groove so that it can be pulled out freely.When the auxiliary end of the slide presser is lifted up while the auxiliary leg is pulled out, the principle of the main leg is There is provided a content presser in a frame, wherein a contact fulcrum becomes a position of an opening edge of an inner groove wall so that a reverse foot part is laterally detached from a check claw.

  Since the content presser in the frame is configured as described above, inserting the main and secondary legs into the frame mounting groove to attach to the frame results in elastic deformation to pass only one reverse leg of the main leg. The insertion resistance is reduced by half compared to the two cases. Moreover, in the pushed-in state, the secondary leg pushes the inner surface of the outer groove wall to push the main leg against the inner groove wall, thereby holding the hook of the reverse foot portion against the check pawl.

  Therefore, when the slide holding piece is pushed out to the contents, the place where the upper end of the outer groove wall (the waist and the secondary leg) contacts becomes a fulcrum, and the reverse foot further bites into the check claw. Therefore, the catch is further ensured, and therefore, it is reliably held no matter how strong the pressing of the slide pressing piece against the contents is. Further, when the hook portion of the reverse foot portion with respect to the check claw is regarded as a fulcrum, the action of the auxiliary leg as the action point portion being pushed into the mounting groove works, and this also ensures the certainty of holding the contents. .

  In the second invention, a mounting groove for the content presser is provided in the rear opening or inner opening of the frame at the rear part of the frame to be framed, and the inner surface of the inner groove wall on the inner side of the frame is reversed from the rear side in the groove. The frame where the pawls project is composed of a combination of a base made of plastic and a slide press piece of the contents, of which the base has a waist that is in contact with the back of the frame and elastic in the mounting groove. A monopod that can be pushed in while deforming is projected directly from the waist or via a detour piece, and a slide groove having a lateral width extending inward and outward is formed in the waist, while the slide presser piece is formed on the base body. An elastically deformable plate-like shape that is held in the slide groove, and is formed with a reverse leg portion that can be prevented from escaping to the check claw of the mounting groove on one leg of the base body, and further on the base body The reverse foot By providing a resiliently deformable contact with the groove wall so that it can be applied to the check pawl so that it cannot be pulled out, when the drawer end of the slide presser piece is lifted while pulling out a monopod, A content presser in a frame is provided, wherein a contact fulcrum is a position of an opening edge of an inner groove wall so that a reverse leg portion of a monopod is laterally removed from a check claw.

  Since the contents pressing tool in the frame is configured as described above, the elastically deformable contact portion with respect to the groove wall serves the same function as the auxiliary leg in the first invention, and thus has the same action as in the first invention.

  Next, when removing the presser, the slide presser piece is pulled out and its pull-out end is lifted. Then, the secondary leg is pulled up from the mounting groove, and this time, the upper part of the inner groove wall serves as a fulcrum and the slide presser piece reverses. The part will be displaced laterally (outward) from the check claw. At this time, the reverse leg allows the inversion by elastic deformation, so that the reverse foot portion is surely detached.

  As described above, according to the present invention, when attaching to a frame of a frame, the resistance to be inserted into the mounting groove as the dovetail is halved, so that it is suitable for one-touch operation mounting, and thus the resistance is low. By utilizing this, it is possible to catch the reverse foot part with respect to the check claw relatively more than before, so the hook of the reverse foot part can be deepened to further increase the certainty of holding the contents. Also, it is possible to sharpen the frame by reducing the groove width of the mounting groove, and when removing the presser, the lever principle works well and the reverse foot part can be easily detached from the check pawl. There is an excellent effect that it is easy to remove from a single touch.

  In addition, according to the seventh aspect of the present invention, when the stability of the mounting is improved by expanding the width of the base body, the resistance of insertion into the mounting groove can be reduced by the notch, and the base body and the slide presser piece can be reduced. And easy to assemble.

  Next, an embodiment of the present invention will be described with reference to the drawings. For the mounting groove provided in the frame of the frame, the embodiment is illustrated by dividing it into a rear opening type and an inner side opening type. However, as long as the technical idea is the same, even if the mounting groove is an inwardly inclined type as the middle, it does not contradict the gist of the present invention and belongs to the scope of the present invention.

  FIGS. 1 to 5 show an embodiment of a rear opening type. In order to mount the presser P for the contents W on the frame 1 of the frame G, the mounting groove 2 is opened on the back surface. The presser P includes a bifurcated base body 4 and a slide presser piece 5 curved in an arcuate shape. In addition, the content W collectively refers to, for example, a transparent plate, a work, a back plate, and the like stored in the frame 1.

  The frame 1 is made of an aluminum extruded shape, and an H-shaped part having side walls at the rear is formed to form a mounting groove 2 composed of both inner and outer groove walls 3 and 3a, and the contents W (transparent plate) at the front end. ) Is formed. Therefore, in principle, the work is taken in and out after the presser foot P is released.

  In the case of this embodiment, the mounting groove 2 has a straight surface 12, 12 below the inwardly inclined surface of the mouth on the inner surfaces of the inner and outer side groove walls 3, 3a due to the fact that it is formed in the shape of a mouth opening. (FIG. 1). By providing a wide space 13 at the lower end of the groove, the inner groove wall 3 has a step that becomes an angle of attack perpendicular to the direction of removal, and a long irregular check claw 7 extending from the mouth to the straight surface 12 is formed. . The inner groove wall 3 having the check pawl 7 is on the side of the frame inward rotation R. On the other hand, in the outer groove wall 3a, the lower end of the straight surface 12 is curved to be a relief surface without being caught.

  The base body 4 and the presser piece 5 of the presser P are each formed of a hard plastic that can be elastically deformed. Of these, the main body sub-legs 19 and 20 hang down from the waist 18 of the base body 4. In other words, it has a lower body shape, and a reverse foot portion 21 protrudes only from the main leg 19, and the auxiliary leg 20 is formed in a thin shape outside the lower end so as not to resist insertion. Further, a slide groove 25 through which the slide presser piece 5 passes is provided in the waist 18 of the base body 4, and the groove 25 is formed at a position where the slide presser piece 5 is joined to the back surface of the frame 1.

  Next, the slide holding piece 5 is an elastic body in which a rectangular thin plate is high in the center and is curved in an arcuate shape, but an upward finger hook 27 and a downward pressing edge 29 are projected in a vertically integrated manner at the tip edge, A through hole 31 is provided in the center of the width of the front end portion to be secured to the back plate or the like by scissors. In addition, the base end portion is provided with a wide slot 33 and an opening 35 of the slot 33 is provided at the center of the tip, and the dimension between the corner portions 37 and 37 serving as stoppers at both corners is set as the opening 35. I was able to reduce with. That is, when attaching the slide holding piece 5 to the base body 4, in the case of this embodiment, although it has a stopper, it was made easy to pass from the end there to the slide groove 25.

  The main and secondary legs 19 and 20 of the base body 4 hang substantially parallel so as to be in close contact with both the straight surfaces 12 and 12 of the mounting groove 2, and when inserted into the mounting groove 2, When the distance between the legs 19 and 20 is once narrowed by the amount of protrusion, the reverse foot 21 is caught by the check claw 7. In this case, since the amount of deformation is only the amount of protrusion of one reverse foot portion 21, the insertion resistance does not become excessive even if the protrusion dimension is deeply applied to the check claw 7. In addition, the shape of the base body 4 etc. so that the contact parts 41 and 51 of both the legs 19 and 20 closely_contact | adhere to both the straight surfaces 12 and 12 of the mounting groove 2 may act on the direction which expands both the straight surfaces 12 and 12 outside. It is desirable to configure.

  As described above, the base body 4 is generally bilaterally bifurcated. However, if the base body 4 is mistakenly inserted to the left and right, the reverse foot portion 21 of the main leg 19 hits the inner surface of the outer groove wall 3a without being caught, The missing secondary leg 20 hits the check claw 7 of the inner groove wall 3, and the insertion is not stable and it is easy to come out without demonstrating the function of holding the contents W, so that the mistake is immediately noticed. In this way, trouble in use is prevented in advance.

  After the presser P is attached, the content W is pressed by elastic deformation as shown in FIG. 2 in a state where the presser piece 5 is extended to the longest (bellowing to the content W) in principle. In this state, the reaction force T (FIG. 2) that the presser piece 5 presses the contents W not only acts to push the auxiliary leg 20, but also the reverse foot portion 21 with the upper end portion of the outer groove wall 3 a as the fulcrum E. Acts in the direction Q where it is caught more deeply on the check pawl 7.

  When replacing the content W, the presser piece 5 is pulled out of the content W by pulling it out (the two-dot chain line in FIG. 5). Further, when the presser P is removed, the operation is performed in the state of being pulled out. At this time, the pull-out end 5a of the presser piece 5 is lifted up (FIG. 5). Then, first, while the outer secondary leg 20 is elastically deformed and pulled out, the upper end of the straight surface 12 and the perforated slope, and further the upper end surface of the inner groove wall 3 become fulcrums Sa, Sb, Sc sequentially, and the principle of the insulator Thus, the main leg 19 is reversed in the lateral direction F (FIG. 5), and the reverse foot portion 21 is detached from the check claw 7, so that the legs 19 and 20 can be pulled out further. Therefore, there is no resistance or catching during pulling out.

  The base body 4 was formed in a wide lateral shape, and a notch 22 was provided in the center of the width so that resistance to insertion was reduced. In such a case, since the slide groove 25 can be widened by opening the crotch, the slide presser piece 5 can be easily inserted for assembly.

  FIG. 6 shows another shape of the mounting groove 2, and the inner surfaces of the inner and outer groove walls 3, 3 a are straight surfaces, and the check pawl 7 is formed midway in the height of the inner groove wall 3. . In this case, the upper end surface of the inner groove wall 3 of the mounting groove 2 serves as a fulcrum S when the presser piece 5 is lifted.

  FIGS. 7 to 9 show an embodiment in which the mounting groove 2 is an inner side open type. In this case, the frame 1 avoids the rear surface opening in order to make the appearance of the rear surface. A rear wall that refracts and protrudes from the rear end on the outer side wall is formed as an outer groove wall 3a, and an inner groove wall 3 is provided below the rear wall to constitute the mounting groove 2. The inner shape of the mounting groove 2 is almost the same as that of the first embodiment, so the same reference numerals are given and the detailed description is omitted. Similarly, both inner surfaces may be straight (see FIG. 6). In any case, the check pawl 7 is formed in the inner groove wall 3 on the side of the frame inward rotation R as in the case of the above embodiment.

  The presser P is similarly composed of the base body 4 and the presser piece 5, but the base body 4 is different from that of the above embodiment, and the lower surface portion 18 a of the waist portion 18 joined to the outer groove wall 3 a. The detouring piece 43 is suspended from the end of the mounting groove 2 so as to seal the opening, and both legs 19 and 20 are projected sideways on the detouring piece 43, and the reverse foot 21 is formed at the tip of the lower main leg 19. Is formed.

  FIG. 8 shows a state in which the presser P is attached and the presser piece 5 is holding the content W, and the reaction force T that the presser piece 5 presses the content W by elasticity is reversed by the reverse foot 21. It acts as a force in the direction Q that is deeply applied to the pawl 7. In this case, the outer surface of the outer groove wall 3a is considered to be a fulcrum as a whole. Further, in this embodiment, the outer groove wall 3a is sandwiched between the lower surface portion 18a of the waist portion 18 and the auxiliary leg 20, and the catch of the reverse foot portion 21 with respect to the check pawl is held. Is secured.

  However, when the presser P is removed (FIG. 9), the lip of the inner groove wall 3 with which the end of the detour piece 43 comes into contact becomes the fulcrum S, so that the reverse foot 21 can be removed from the check pawl 7 in the direction F. In the same way as in the above-described embodiment, the force works and the auxiliary leg 20 allows it by deformation.

  FIGS. 10 to 13 can be said that the leg inserted into the mounting groove 2 can be said to be a single leg. In principle, the leg is the same as the above embodiment, and the auxiliary leg 20 is an elastically deformable contact portion 41 with respect to the groove wall. Fulfills the same function as the auxiliary leg 20 in the above embodiment. When the slide presser piece 5 is pushed out to the contents W (solid line), the reaction force T for pressing it is that the waist 18 becomes the fulcrum E at the upper end of the outer groove wall 3a, and the reverse foot 21 is fitted deeply into the check claw 7. When the slide presser piece 5 is pulled out and the base end portion (two-dot chain line portion) is lifted (arrow), the upper end of the inner groove wall 3 becomes a fulcrum S, and the reverse foot portion 21 is non-returned. Since it comes off the nail 7, the monopod 24 can be pulled out. The above is the same as that of the said Example.

  In FIG. 10, the monopod 24 protruding from the waist portion 18 has a meandering shape, has a contact portion 41 joined to the inner surface of the outer groove wall 3 a at the proximal end, and a reverse leg portion via a meandering piece 42. The portion having 21 is pressed against the inner surface of the groove, and thus the reverse foot portion 21 is held in the check claw 7. In this case, it is desirable to configure the shape of the monopod 24 so that the elasticity of the monopod 24 acts in the direction in which the side groove wall 3a is pushed outward at the contact portions 41 and 51 in contact with the inner surface of the side groove wall 3a. .

  In FIG. 11, the monopod 24 protruding from the waist portion 18 has a bent or hook-shaped bent shape that reversely bends, and the reverse portion serves as a contact portion 41 for the inner surface of the outer groove wall 3 a with respect to the check claw 7. The engagement of the reverse foot 21 is maintained. Also in this case, the shape or the like of the monopod 24 is configured so that the elasticity of the monopod 24 acts in the direction in which the side groove wall 3a is pushed outward at the contact portions 41, 51, 61 with respect to the inner surface of the side groove wall 3a. It is desirable.

  In FIG. 12, the monopod 24 is vertical as in the first embodiment, but the elastically deformable vertical piece 20a sandwiching the upper end portion of the inner groove wall 3 is projected from the waist portion 18 as contact portions 41 and 51. . In this sandwiched state, the hook of the reverse foot 21 with respect to the check claw 7 is held. In this case, it is desirable that the contact portions 41 and 51 are configured to sandwich the inner and outer surfaces of the inner groove wall 3 by the elasticity of the monopod 24 and the vertical piece 20a.

  In FIG. 13 and FIG. 14, the monopod 24 is formed in a cylindrical shape that is elastically deformed and inserted into the mounting groove 2, and a reverse foot portion 21 that hooks on the check claw 7 is provided on one side of the lower end. Therefore, the portion on the opposite side of the reverse foot portion 21 becomes a contact portion 41 with respect to the outer groove wall 3a, and the engagement of the reverse foot portion 21 with the check claw 7 is maintained by elastic deformation accompanying the cylindrical shape. The cylindrical shape of the monopod 24 is preferably circular or elliptical. Also in this case, in the contact portions 41 and 51 with respect to the inner and outer groove walls 3 and 3a, it is desirable to configure the cylindrical monopod 24 so that the inner and outer groove walls 3 and 3a are pushed outward.

  FIG. 15 shows a case in which a convex (or concave) finger hook 45 is provided in the center of the slide presser piece 5, and in order to insert and remove the slide presser piece 5 with the finger hook 45, a through-hole by a notch is formed at the center of the width of the waist portion 18. 47 is provided. This can be applied to any of the above-described embodiments, but in that case, it is desirable not to provide a notch (22) which is bifurcated on the main auxiliary leg or the monopod.
