France-France (FR) 7323252 (71) Usiflamme SA, Moncor, 1752 Villars-sur-Glane, Switzerland-Switzerland (CH) (72) Rpbert Hocq, Boulogne, France-France (FR) (? M Berggren Oy Ab (54) ) Writing device with a holder for attaching the device to a pocket, for example - Screw with a holder for attachment to a pocket

The invention relates to a writing instrument or the like with a retractable holder for attaching it, for example to a jacket pocket.

By writing instrument is meant here all kinds of instruments for writing by hand, in particular a dry ink pen, a ballpoint pen or a pencil with a holder which can be pulled into either the pen cap or its body. Such objects within the meaning of the invention can also be all kinds of objects with a holder for attaching them to, for example, a suit pocket or belt, such as mini-pocket lamps.

Known pens with a retractable holder can be divided into two groups:

In the first group, they have a retractable writing tip and a retractable holder located in the body of the writing instrument, i.e. a pen, and further have a mechanism by which the writing head 60167 is pushed out and the holder is pulled in and vice versa. In these pens, the holder and the writing head, respectively, move between two locking positions, one retracted and the other extended. In this type of pen, the holder is locked in its extended position, in which case it acts like a fixed stop, i.e. only under the influence of its own flexibility, which means various inconveniences.

Such a holder is particularly unsuitable for attaching a pen to pockets of different thicknesses, and in particular to very thin pockets, and the need to make the holder very flexible again reduces its durability and carries the risk of breakage if used too harshly.

In another group of known pens with a retractable detent, on the other hand, there is a holder which can be pulled into the pen cap, for example, and which is continuously pulled towards the retracted position by a resilient return member so that the detent is pressed against the pocket mainly by

However, proposals for these types of pens have not led to the manufacture of such pens on an industrial scale, in particular because the user must act directly on the detent to get it in the extended position while attaching the pen to a pocket, which requires a complicated, intricately movable holder.

To avoid this inconvenience, it has already been proposed to provide the holder with an extension that protrudes either outside the pen or on the opposite side of the holder to allow the user to act against this part against the elastic return member. However, these solutions have not been satisfactory in practice. Adapting a part of the holder outside the cap to extend to the other side of the holder means an aesthetic and uncomfortable external protrusion for the pen as a whole, which is specifically avoided by pulling the holder into the pen cap or body while using the pen. Adapting a portion of the protruding holder to the outside of the outer surface of the pen — although not the inconvenience mentioned above — requires a complex and variable shape of the holder, which in turn makes it difficult to adjust the holder effectively. Moreover, the small distance in question in this outer section 3 60167 prevents the use of a suitable return member with a certain progressivity, i.e. the continuity of the return force. Attempts have been made to overcome these inconveniences by providing the pen with a holder-independent axially movable pusher equipped with a ramp for pushing the bent end of the holder protruding into the hat laterally, with a leaf spring acting on this end to pull the holder towards its retracted position. However, this solution means poor controllability of the holder and the risk of the bent end of the holder being struck, all the more so because, due to various external causes, the pen detents generally do not last exactly parallel to the pen axis.

The present invention seeks to overcome these drawbacks by providing a pen or the like having a retractable retainer of the type in which the retainer is pulled toward the retracted position to provide effective compression when the pen is carried in a pocket and in which the retainer is retracted when the pen is ready to write, and the invention seeks to enable the user to fine-tune the movement of the holder with a particularly constant force, which may also be continuous, while at the same time making the holder durable, thus protecting it from damage.

More particularly, the invention relates to a writing means having a holder for attaching the means to a pocket, for example, the holder is adapted to be moved in and out of the opening in the wall of the to the upper end portion so that the holder moves outward against the force of at least one return spring. The invention is characterized in that said end portion of the holder is a guide portion having a dimension in the longitudinal direction of the writing instrument multiplied by its thickness and having a notch inside the wall of the instrument at a free longitudinal edge of the end portion on the surface to guide the lower edge of the end portion of the holder and between the two branches at the top to guide the side surfaces of the end portion.

Thus, the end of the holder is preferably fully guided throughout its distance, the end of the holder being preferably in the shape of a parallel pipette and its underside cooperating with a transverse guide surface extending substantially the entire length of the pen, and its two parallel axial sides guided by two guide surfaces relative to the guide surface, and likewise extend the full length of the cap required. The different guide surfaces can advantageously be a retaining piece arranged in the pen body or in the pen cap.

The action of the return member on the sliding end of the holder preferably occurs in a direction substantially parallel to the direction of sliding of the holder head.

The sliding pusher is preferably fitted to the end of the pen body or cap, which also houses the holder, and in a particularly preferred embodiment, said pusher cooperates with said end by means of a ramp inclined both in the direction of movement of the pusher and in the direction of sliding of the holder. This ramp can advantageously co-operate with the wheel, the ramp being attached to the pusher and at the end of the wheel holder, for example. The ramp is preferably arcuate to provide a continuous counterforce to the clamp under the action of the resilient return member. The latter may preferably be a spring, one leg of which acts on the end of the holder, while the other is wedged against a suitable surface of the pen cap or body, and which spring preferably has central coils to provide a more regular force. In a particularly preferred embodiment, the wheel axis of the holder head extends on both sides over the holder head and the return member is formed of two parallel springs acting respectively on the two projecting ends of the wheel shaft.

The retainer is preferably inserted into the opening in the upper end of the pen cap or body and is held inside the pen by a lower body which abuts a stop member in the pen body or cap, such as a part left intact in the retraction slot of the holder. This lower part is fixed against the retaining piece with a screw. If this lower part is supported by a hat, it can advantageously be made as a clip which receives the writing head of the pen, and can be provided with latch locking pins cooperating with the opening of the pen tip to hold the hat axially against the body of the pen.

According to an application example, the upper part is adapted to guide the assembly formed by the pusher and the ramp. This body has an internal cavity for the ramp and the end of the holder and two side pawls which receive the ends of the spring or spring support shaft, which support shaft is in turn attached to the retaining body, so that the upper body is thus connected to the retaining body.

5,60167 This body may advantageously have a sliding plate along the wall opposite the end of the pen holder, for example of hardened steel, against which the assembly of pusher and ramp can slide to protect the wall itself from strong pushes which this assembly may apply to it.

Other advantages and features of the invention will become apparent from the following description, which shows an embodiment of the invention by means of the accompanying drawings. In these drawings: Figure 1 shows a perspective view of a pen according to the invention; Fig. 2 is a longitudinal section of the pen cap, substantially in the direction of the roller axis; Fig. 3 is a longitudinal section of the hat in a direction perpendicular to the axis of the roll and passing through the roll; Fig. * 1 is a view according to Fig. 3 with the holder in the extended position; Fig. 5 is a sectional view taken along line V-V of Fig. 2; Fig. 6 shows the connection of the pen cap and body in the sectional plane according to Fig. 3; Fig. 7 shows the joint in the plane of Fig. 3; Fig. 8 is a view according to Fig. 5, but showing another embodiment of the invention; Fig. 9 shows this embodiment example in the view of Fig. 1 with the end of the holder removed.

The pen shown in Fig. 1 has a pen body 1 provided with a cap 2 with a retractable holder 3. The pen body 1, like the cap 2, consists essentially of a hollow cylinder of substantially oval cross-section.

The holder 3 can be pulled into the hat 2 by pushing it into the slot 4. The slot M has a break 5 formed by an uncut part of the cylinder wall 2, which is simply inserted some distance into the slot.

A retaining piece 6 with a thinner central part 6a is arranged inside the hat, which extends as two vertical paws 6b, between which a horizontal guide surface 6c is left. As can be seen in Figure 4, each paw 6b comprises an elongate horizontal space, the upper part of which abuts the part 6d which is contracted in the horizontal direction relative to the other paw 6 60167 5b. The retaining piece 6 is fixed to the body of the hat by means of a receiving pin 7 of the writing head 8 of the pen body 1. Such a clamp 7 preferably has two resilient pawls 7a terminating in hooks 7b which penetrate the corresponding opening 8a of the writing head to keep it axially locked when the hat is connected to the body 1. In its attachment, the lower part, i.e. the clamp 7, pushed against the lower part 5 , so that it cannot continue its upward movement. The screws 9 connect the pieces 6 and 7 to each other by means of an intermediate deformable tightening joint 10.

A top piece 11 with a central cavity 11a and two side paws 11b is fitted to the upper part of the hat 2, which can be seen in Fig. 5, having a vertical slot 11c with resiliently deformable edges and a notch in each slot 11c of one of the horizontal shafts 12. a head, the central part of the shaft of which passes through the corresponding opening of the part 6a of the holding piece 6. In this way, the body 11 is brought into axial contact with the body 6, while the assembly formed by the bodies 6, 7 and 11 in turn remains in place against possible lateral movement by means of its external shapes cooperating with the cylindrical inner shape of the hat.

At the top of the body 11 there is a sliding push 13> which is cylindrical in shape and thus continues the cylindrical shape of the hat 2 and slides up to the end of the body 11. The decorative ring 14 in the hat covers the boundary between the cylindrical surface of the pusher 13 and the rest of the part 2 of the hat. The push 13, which is pulled apart from the body 11 by the return spring 15, is fixed by a screw 16 in the opening 11a of the body 11 to the movable arm 17 · This arm 17 has a ramp 18 at its lower part, which is bent according to the second degree arc. Therefore, when the pusher 13 is pressed, said pusher is made to slide in the vertical direction downwards, and then the ramp 18 descends in a vertical pivoting movement, the assembly formed by the ramp and the pusher returning elastically upwards by the spring 15 when the pushing ceases.

The detent 3 has a relatively thick end 3a in the vertical direction, which is complete from the part closest to the detent body 3 (as shown in Fig. 3) and in contrast has two vertical paws 3b so that when the detent is in the retracted position as shown in Fig. 3 3 extends from the right, 7 ^ 60167, i.e. from the detent 3, all the way to the left-hand part of the hat 2. The shaft 19 is made fixed with the two paws 13b by guiding through the respective openings of said paws as its ends come out of it, as can be seen from Fig. 2.

A rotating wheel 20 is arranged in its central part, i.e. in the space between the paws 3b, which cooperates with the ramp 18 supported by the arm 17; the part supporting the ramp 18 of the arm 17 is thin enough to fit in the space between the paws 3b.

The two springs 21 are wound around the part between the two pieces 6 of the shaft 12 and the paws 11c and the shorter end of these springs rests against the edge 6e of the body 6 and the longer end against the protruding ends of the shaft 19 with two grooves facilitating contact with the springs.

Starting from the retracted position shown in Figures 2 and 3, when the user presses the hat 13 vertically, he causes the ramp 18 to descend into the vertical passage against the spring 15. As it slides into this passage, the ramp 18 acts on the wheel 20 and pushes outwards the holder head 3a, which laterally engages between the inner sides of the pawls 6b so that the holder end 3a abuts the surface 6c, against which the end 3a and the lower pawls 3b rest. At its top, the end 3a is guided by the bottom 4a of the slot 4. through. A release piece 3c is arranged at each paw 3b, which, by locking against the end 4a of the slot, prevents the head 3a from getting out of the hat. During the lowering of the pusher 13, the lateral outward movement of the head 3a causes the holder 3 and the hat to move away and the springs 21 to be compressed into a pile.

If the bent shape of the ramp 18 is chosen to be suitable, despite the increasing tension of the springs 21, with the pusher 13 depressed, the required counterforce of said springs can be kept constant so that handling the pusher 13 requires a completely smooth and continuous pressing by the user.

At the end of the push, the detent 3 is completely out, in the position shown in Fig. 4. When in this position, the user can hang a hat carrying the pen body 1. He can also, if necessary, use the elasticity of the holder 3 with respect to the end 3a. If the user tends to detach the detent from the hat by pressing the lower part of the holder, the head 3a tends to turn upside down, but since the support area entering the head surface 6c is large, there is no risk of damaging the respective surfaces of the head 3 and the detent body 6.

When the user stops pushing the pusher 13, the springs 21 which support both ends of the shaft 19 push the head 3a back by pushing it transversely inside the hat, while instead the pusher 13 rises upwards with the ramp 18 under the action of the spring 15.

If there is no obstacle between the clamp 3 and the cap 2, the springs 21 return the head to the original position shown in Fig. 3. If, on the other hand, there is an obstacle in between, such as a layer of fabric, this obstacle is pressed between the detent 3 and the cap 2 by the force of the springs 21, so that the suspension is successful, even when the fabric is very thin.

To mount the device on the cap 2, the pusher 13 and the arm 17 are first assembled by means of a screw 16 on both sides of the guide piece 11. The body 11 is then joined to the body 6 by resiliently fitting the paws 11b around the ends of the shaft 12 already fitted with two springs 21. The assembly thus obtained is then pushed in from the upper end of the hat until the narrow edge shoulder of the body 11 abuts the upper end of the cylindrical wall of the hat 2. . The hook-like body is then pushed into the upper part of the slot 4 so that the hooks engage the springs 21 to press down on these springs, whereby the holder end 3a can be pushed out of the slot 4, then the springs are released, which then abut against the ends of the shaft 19.

Then the piece 7 is pushed from the lower end of the hat and a seal 10 is placed between the pieces 6 and 7 and the pieces are joined together with a screw 9-

An embodiment of the invention is shown in Figures 8 and 9, in which the holder has been omitted for clarity.

In this variant, the vertical gap 11'c of the upper body 11 'is in the center of each side paw 11'b and the resiliently deformable edges of this gap have a notch to fit the end of a horizontal axis 12', in this case horizontal in cross section. The central part of the shaft 12 'passes through the opening corresponding to the part 6'a of the retaining body 6'. It is further observed that the body 11 * has a collar 11'd which rests against the upper end of the pen body 2. Otherwise, paragraph 11 'is substantially similar to paragraph 11.

Fig. 9 shows a section similar to V-V, but with the left paw 11b omitted, showing a side view of the detent body 6 'and the assembly formed by the pusher and the ramp. The pusher 13 is preferably made in the form of a single piece in the form of a cylindrical container attached to the part 13'a immediately below it, which has the characteristics of a flexible clamp, so that the cylindrical body 13 can be inserted simply by clamping.

As can be seen from Figure 9, the part of the wall 2 along which the ramp 18 slides is coated on the inside with a steel plate 22 held in place by members 11 'not shown. It has been found that it is at this point that the back tension is at its strongest, so that the steel plate 22 along which the ramp slides avoids excessive pressure on the wall 2.

The detent body 6 'has an upper part with two side paws 6'b, between which a base 6'c is arranged, which is also preferably reinforced with a steel plate (not shown). It can be seen from Figure 9 that each paw 6’b has a higher portion on the inlet side of the pinch and that the paw gap has been removed and replaced by reducing the height of the main body of the paw.

Both side surfaces of the body 6 ', one of which is shown in Fig. 9, have a reinforcement 6'f fitted with coils of a spring 21', the longer branch 21 * a of the spring extending along the side surface of the member 6 'to the other side of the corresponding paw 6'b that it pushes the end of the shaft 19 (shown schematically in Fig. 9). The branch 21'b is immobilized on the corresponding part of the reinforcement 6'f. The side surface of the body 6 * preferably has a second reinforcement which is smaller than the reinforcement 6'f, the branch 21'a moving in this second reinforcement so that the spring 21 'cannot protrude outside the space of the body 6'.

Although the invention has been described above by means of one embodiment, it is clear that it is not limited to this example, but that the device can often be modified in various ways within the scope of the claims.
