Description

The present invention relates to a master key, the type of those who

  include a frame made of profiles and

  a bottom, as well as staples or other elastic fasteners

  similar, which maintain the background, the image and possibly

  plate or transparent sheet of protection

  pressed against one of the frames of the frame and which are

  placed on the bottom by means of a rivet or other

  link provided with a head or other similar stop protrusion.

  A master key of this type is described, for example, in the German Utility Model No. 78 05 519. Each of its staples is U-bent and has near the edge of the bottom a side tongue through which the rivet or other member link. It is then possible to rotate

  staple around the rivet and bring it out of the oc-

  the frame to separate the bottom of the frame, or, on the contrary, to rotate it around the rivet so that its arm free-come to be placed under the

  frame and that it immobilizes the bottom. The disadvantage of this

  the known construction is the complexity of its manufacture, which results from the assembly of the staple and the rivet. A

  automation of production is virtually unrealistic

  ble, because the feeding of the staples to the various sides of the bottom se-

  would be too complicated. In addition, storing funds with staples is difficult because they can

  many funds, which complicates the handling of

of these.

  The simultaneous fastening of the staple and the rivet, which

  makes it necessary to position the staples one by one on the

  is particularly an operation which requires a lot of work, so of expenses, and which

rivets at the same time.

  The object of the invention is therefore to provide a

  everywhere of the aforementioned type, but in which the staples are

  in such a way that, although they are immovable

  also connected by a connecting member provided with a head,

  are therefore captivated once mounted and allow-

  also a quick replacement of the image by another, the establishment of the rivet or other connecting member can be done without the staples have to be brought to the

  riveting machine, several rivets can be mounted simultaneously

dnext in the same background.

  For this purpose, in the master key according to the invention

  the head of the liaison bodies is at a certain

  distance from the rear face of the bottom, each clip has in its attachment area, away from the frame, a

  longitudinal slot, the end of which faces the

  dre presents an enlargement the dimensions of which are

  below that of the aforementioned head, and the length of

  the slot is equal to or greater than the penetration depth

  staple in the frame. This conformation of the staples and the manner in which they are fastened to the bottom of the mat make it possible to first supply it with rivets or other connecting members and then to place

  in the frame the transparent plate or sheet of protection

  possible, the image and the substance, after which the agra-

  can be put in place by bringing the expansion of their slot facing the head of the associated connecting member, then, while exerting a slight pressure, pushing them towards the frame until they snap into this one. So just

  exert on each clip a thrust guided by the slide

  the rivet in the longitudinal slot to fix the said clip on the bottom and to fix it on the frame

  the mat. As can be fixed simultaneously

  if rivets on the bottom and as the gesture of pushing the staples is at least as simple as that of turning them as in the known passepartout, it results

  an indisputable simplification of manufacturing.

  The rivet, preferably provided as a connecting member

  its, can advantageously present between its stem pressed into the bottom and its head a zone of diameter greater than

  that of the stem. This simplifies the implementation of

  vets and proportionally increases the contact area between

  the rivet and the edge of the longitudinal slot.

  The fixation zone, equipped with the longitudinal slot

  the, of each staple can be in the prolongation

  of the spring clip portion and constituted by u-

  spring and tongue connection, maintained

  each other by their own elasticity, the

  zone of junction between the spring branch and the languet-

  you can be a part of the clip between two -inflexions of opposite directions, which extends towards the rear face of the bottom and to which is connected the zone of

  fixing at an angle preferably greater than 900.

  As a result, the fixing zone and in particular the long slot

  the longitudinal axis are more or less in line with

  the spring portion so that the rectilinear thrust

  on the staple also brings this part into

working conditions.

  To simplify the assembly of staples while

  Since these are virtually captive once mounted, the longitudinal slot extends, to pass over the connecting member and under the head thereof, into the region of the staple between the double inflection and the widening of the slot for the passage of the head is located in this area. As a result, when

  staple is mounted, the part of this zone closest to

  the bottom edge protrudes laterally from the lower edge of the

  head of the liaison body and prevents it from separating

  from the bottom. It is particularly advantageous further that the widening of the slot for the passage of the head of the connecting member is, in the working position of the staple, further from the bottom than said head, the distance between the transition angle with the fastening zone and the bottom is greater than that between the widening and this inflection and that the fixing zone

  presents the elasticity of a spring.

  Just then, pushing the staple towards its position

  work, to exert pressure in the Com-

  taken between the two inflections so that the widening of the slot comes to be placed under the head of the liaison body, then, when the head has crossed this zone and

  found in the fixation zone, it is sufficient to stop e-

  exert this pressure so that the part between

  and the inflection of the connection acts as a stop, which prevents the staple from separating from the bottom, even when

  remove from the frame to change the image.

  In another advantageous embodiment, the

  attaching each clip present at the end of

  the longitudinal slit away from the frame a curvilinear profile

  protruding towards the bottom, which abuts, on the one hand with the said bottom and on the other, with the underside of the head of the connecting member. This results in a fixation

  sturdier clip under this head, which is

  at a certain distance from the bottom. The curvilinear profile may be shaped so that the end of the longitudinal slot is at its most salient point towards the bottom. As in an advantageous embodiment, the staple must serve as a suspension member cooperating with a hook or nail attached to a wall, the suspension force is applied to the most favorable place of the body of the connection, that is to say, as close as possible to the background, which

  avoids as much as possible the presence of a couple of

rabies in this area.

  The elastic tongue which extends towards the bottom is advantageously cut by punching in a portion of the spring leg, and then bent towards the bottom. The opening left by punching in the spring leg can be used for hanging on a nail or suspension stud. The clip, constituted by the spring leg, the elastic tongue, and an attachment zone provided with a longitudinal slot and a double inflection, can then be manufactured in a metal blank in a single operation. combining the

punching and stamping.

  Anyway, the invention will be well understood at 1 '

  using the description which follows, with reference to the drawing

  schematic annexed, representing, as an example not

  mitative, a form of execution of this master key:

  Fig. 1 is a side view and partially in section

  longitudinal peg of a staple for the mat according to

  the invention, shown in working position, the elements

  go-anywhere pieces which cooperate with this clip being shown in broken lines; Fig. 2 is a top view of the clip of FIG. 1; Fig. 3 is an end view, rivet side, of the staple

of fig. 1.

  In a mat of the type of that according to the

  In this connection, it is intended to fix in several places a frame 1, elastic clips 2, which hold pressed against a rabbet 3 of a frame 4, the bottom 1, I '

  image to be framed and possibly a plaque or

  the transparent protection of the image. In the embodiment described, the staples 2 are fixed to the bottom 1 by means of a rivet 5, provided with a head 6. It is possible to use in place of the rivet a suitable connecting member having

  a head or other similar stop protrusion.

  It can be seen in Figure 1 that the head 6 of the rivet 5 is at a distance from the rear face 7 of the bottom 1. It can be seen, in particular in Figure 2, that the clip 2 has in its fixing area 8, remote from the frame 4, a longitudinal slot 9 whose end 10 facing the frame has a widening 11, the dimensions of which are greater than the diameter and also the height of the head 6 of the rivet (see also FIG. ). FIG. 1 makes it easy to realize that this embodiment makes it possible to fix the rivet 5 on the bottom 1 before mounting the elastic clip 2, the latter being then

  pushed by its longitudinal slot 9 under the head 6 of the ri-

  vet. This push in the direction of arrow PF1 also has

  effect of bringing the free end of a branch of

  12 out of the elastic clip inside the frame profile. To keep the bottom 1 pressed against the rabbet 3, the clip 2 comprises, in addition to the spring leg 12, an elastic tongue 13 which forms the other leg of the reel, V-shaped out that includes the clip and whose free end

  takes support against the bottom. The V-shaped spring can be replaced

  placed by a U-shaped spring when other elements of construction must engage between the branches 12 and 13. It should be mentioned that in Figure 1 the spring portion of the clip 2 is already under tension, the branch 12 and the tongue 13 being further apart 1 '

  one another when their free ends do not co-operate

  not respectively with Box 4 and Bottom 1.

  The distance between the rivet 5 and the edge 14 of the bottom

  1, the total length of the elastic clip 2 and the length

  longitudinal slot 9 have between them

  ports such as the clip 2 takes its working position re-

  shown in Figure 1 and engages in the profile of the

  when the end 15 of slot 9, which is remote

  frame, abuts against the rod 16 of the rivet, or more precisely against an area 17 of this rod. It can be seen in Figure 1, in fact, that the rivet has between its head 6 and the portion of its rod 16 which is driven into the bottom 1, a stop zone 17 whose diameter is greater than that of the rest of the rod. Thanks to the resulting shoulder, the head 6 is held in a simple manner at the desired distance from the bottom 1. In addition, the contact surface between the rivet and the edge of the slot

9 is bigger.

  It can be seen in addition to FIG. 1 that the spring leg 12 has a length which is greater than that of the tongue 13 by at least the depth of its penetration.

  in the profile of the framework 4. It is clear, however,

  that the support zone 18 of said tongue 13 can be located as close as possible to the edge 14 of the bottom 1, which ensures a favorable transmission of the force which tends to move the two branches 12 and 11 of the spring between a point of frame 4 and the rebate 3 of it

through the bottom 1.

  The attachment zone 8 of the elastic clip 2 and its longitudinal slot 9 are in the extension of the two-branch spring formed by the branch 12 and the tongue 13, the connection zone of the two branches or zone 19 being defined between two inflections of meaning

  opposite of the staple 2 and extending towards the

  this rear 7 of the bottom 1. The fastening zone 8 is connected

  to the inflected zone 19 by forming with it a higher angle

  at 90. Slot 9 extends into the zone

  bent 12 and its widening it for the passage of the head 6 of the rivet 5 is also provided in this area. It can be seen in Figure 1 that the enlargement 11 is, in the working position of the staple 2, higher above the bottom 1 than the rivet head 6, that the inflection 20 between

  the zone 19 and the fixing zone 8 of the clip is separated

  from the rear face 7 of the bottom by a greater distance

  re to that which separates it from the enlargement II and that the fastening zone 8 also forms spring. To push the staple 2 into the frame profile, it begins by placing it on the bottom 1 so that the enlargement 11 comes opposite the side of the rivet 5 facing away from the

  edge 14. Then press the clip, which has the effect of

  fet to apply against the bottom 1 the free end of the

  tongue 13 and especially the fixing zone 8. It is

  the abutment zone 21 between enlargement 11 and

  the inflection 20 can pass under the rivet head 6, when

  that the staple 2 thus "flattened" is pushed in the direction of

  arrow PF1. When this part of the inflected area

  19 has passed the rivet head, the spring can be partially relieved, so that in the event of involuntary retraction of the staple, the portion 21 abuts against the rivet head, preventing the staple from separating from the rivet. background. If it is desired to remove the staple, it is enough to "flatten" again to pass the part 21 under the rivet head. The fastening zone 8 has at the end 15 of the longitudinal slot 9 a curvilinear profile 22, which projects towards the bottom 1 and bears against both the bottom and against the underside of the head.

  rivet 6. It is clearly seen in Figure 1 that in the

  In the working position of the clip 2, the fastening area 8 ap-

  directly on the underside of the head 6, but from there, towards the end 15 of the longitudinal slot 9, against which abuts the enlarged portion 17 of the rod 16 of the rivet, down to the face back 7 of the bottom 1. The rivet head 6 is therefore a

  a sort of fulcrum for the entire elastic staple

  2, while at the same time a suspension force acting in the direction of the PFI boom was transmitted to the rivet 5 at a point as close as possible to the bottom 1. The rounding of the profile curvilinear 22, as well as that provided near the free end 18 of the

  tongue 1, facilitates the sliding of the staple on the

  this back 7 of the bottom 1, slip that otherwise would be

  made difficult by the pressure exerted on these two extremes

  the staple on the said face 7. The rivet 5 does not undergo

  practically a shearing effort and no ef-

  bending strength, when staple 2 is used, like this

  it is desirable to suspend the mat according to the invention to a hook, a nail, etc. The curvilinear profile 22 is also shaped so that the end 15 of the longitudinal slot 9 is located opposite its point

the most salient.

  It is particularly advantageous that the staple

  2 forms a single piece of steel for

  spells and be manufactured by punching and stamping. com-

  clearly show me in Figures 2 and 3, the resilient tongue U is punched in a portion of the spring leg 12, and then bent down. We get

  an opening 23, by which the staple can be

  hanging on a nail, hanging from a hook, etc. com-

  this opening 23 extends almost to the frame 4, the engagement of the suspension element is effected under favorable conditions, this element can penetrate to the inside of the profile of the frame, when it s is a hook. It can be seen again clearly in FIG. 1 that in the zone of the branch 12 close to the inflected zone 19, there is provided a deformation 24, for example a curvilinear profile projecting upwards, which can serve as a catch for pushing the staple 2. One or more fingers can easily be supported on this projection 24 (which extends over the entire width of the branch 12, as can be seen

  in Figure 2), when, to bring the clip into its po-

  Working position and mount it on the rivet 5, it is necessary to exert a pressure in the direction of the bottom 1 and in the direction of the arrow PF1. Conversely, for disassembly,

  this projection 24 also offers a convenient grip.

  In particular, in the case of a combination of the characteristics

  described above, we obtain a

  se-everywhere in which the rivets 5 can be mounted

  on the merits in a rapid and rational manner, several

  vets that can be placed simultaneously. This results from the fact that the staples do not have to be riveted directly on the bottom. Their mounting on rivets is almost

  automatically during the movement anyway indis-

  thinkable to bring them into the clamping position, which

  gives them the added advantage of being able to

  mounted without removing the rivets. This arrangement is further advantageous in that, as a precautionary measure, it is possible to fix in the bottom 1 more rivets 5 than is necessary.

  reasonable amount of staples. 2. There is therefore a choice

  staples where they seem most useful. Lors-

  that we want to replace the image, this arrangement also allows an extremely simple manipulation of the staple, it does not have to pivot or tilt, but, after pressing on it, is pulled until part 21

  come into abutment against the rivet head 6. This does not preclude

  Do not swivel the staple around the rivet in either direction. However, because of its tension

  spring, it is immobilized by adherence in all

in an uncontrolled way.

  As it goes without saying and as it is clear from what

  precedes, the invention is not limited to the form of

  which has just been described by way of example only; it embraces, on the contrary, all variants.
