Description

Device intended to ensure the connection of straps, objects or parts of clothing

Technical field of the invention

The invention relates to a device for connecting straps, objects or parts of clothing. In particular, the invention relates to such devices composed of two pieces which can be fitted into one another.

Technical background

Devices intended to ensure the connection of straps, objects or parts of clothing are widely used in the textile industry, leather goods and sports equipment of all kinds.

For example, backpacks and satchels are often equipped with this type of device to close the leaf thereof.

These devices can have various geometric shapes. On the other hand, they generally include a male part and a female part defining a cavity intended to receive the male part. Once the male part is engaged in the female part, the assembly allows you to connect straps, objects or clothing.

Although these devices serve their purpose, they are not without drawbacks.

In these devices, the male part is partly inserted inside the female part. According to a known version, the most widespread, the female part has side openings in which flexible side legs of the male part engage to make the whole integral.

In order to separate the male part from the female part, a user exerts pressure on the flexible side tabs of the male part. The flexible side legs of the male part move closer to each other and come out of the side openings of the female part. The male part then disengages from the female part.

This type of connection device has several drawbacks. It is common for the user, especially when the latter is a child, to get his fingers caught between the male part and the female part when they move relative to each other during the separation. In addition to an unpleasant sensation, the user can injure himself in the most severe cases.

Another drawback of these devices is that depending on the dimensions of the parts it can be difficult to act on the side legs of the male part. For example, when the device is small, it is difficult for the fingers of an adult to deform the side legs of the male part because the side openings of the female part are particularly small to allow the passage of the finger. .

According to another known version of these devices, the female part has side openings. The male part is inserted into the female part so that the side legs surround the female part and fit into the side openings from the outside and not from the inside like the version previously described.

A drawback of these devices lies in their low mechanical strength. Indeed, the flexible side tabs of the male part are often subject to breakage due to their reduced thickness which allows the flexibility necessary for their use to be conferred.

The invention aims to remedy the aforementioned drawbacks.

To this end, it is proposed first of all a device intended to ensure the connection of straps, objects or parts of clothing in which the latter comprises:

- a deformable female part comprising a reception area,

- a rigid male part intended to be inserted at least in part into the reception area of the female part, the male part then being integral with the female part when said male part is inserted into said female part,

and wherein the female part comprises at least one movable area so that setting in motion of said at least one movable area allows the male part to be disengaged from the female part

This device advantageously makes it possible not to get your fingers caught between the male part and the female part when they move relative to each other during the separation. No unpleasant sensations are felt and there is no risk of injury. Another advantage is that whatever the dimensions of the device, the disengagement is easy to achieve. Another advantage is that due to the fact that the male part is rigid and therefore does not include any flexible part, the mechanical resistance to tensile stresses is significantly increased,

device in which:

the female part comprises a body defining two distinct lateral cavities separated from each other by a clearance space,
the male part has two lateral insertion pins, each lateral insertion pin being intended to be inserted into a lateral cavity,

Various additional features can be provided alone or in combination:

- the female part comprises two lateral uprights extending substantially in a longitudinal direction of the device in the extension of the lateral cavities, said lateral uprights being interconnected by an end edge and together defining a receiving hole for straps, objects or part of clothing, and wherein said side posts and / or the end edge are adapted to elastically deform to allow the side cavities to move during the insertion of the male part into the female part, and to allowing said side cavities to return to an initial position when the male part is disengaged from the female part;

- the lateral insertion pins are connected by a stiffening wall intended to stiffen the male part so that the lateral insertion pins remain stationary during insertion into the female part;

- each side cavity has a groove made in the inner side wall, said groove extending laterally along a transverse axis of the device from the reception area to the clearance space located between the side cavities and in which the grooves are suitable for allowing the passage of the stiffening wall of the male part;

- each lateral insertion pin comprises a hook and each lateral cavity comprises an attachment zone in the form of a reservation made in the inner side wall, the shape of the reservation being substantially a counter-impression of the hook, a device in which the hook being in contact with the inner side wall during the insertion of the male part into the female part;

the lateral cavities are interconnected by a secondary return spring, said secondary return spring being able to return said lateral cavities to the initial position when they are displaced from said initial position;

- the female part has an entry edge through which the male part is inserted and a distal end opposite the entry edge where the lateral cavities are connected to each other by the secondary return spring;

- The secondary return spring is of substantially semi-circular shape;

- the female part has a receiving hole for straps, objects or part of clothing, said receiving hole being bordered by a flexible end edge capable of being elastically deformed;

- the end edge comprises a weakened zone so that the end edge has, at the level of said weakened zone, a thickness measured in a longitudinal direction of the device less than a thickness of the rest of the end edge measured along said longitudinal axis;

- the female part has an entry edge through which the male part is inserted and a distal end where the lateral cavities are not interconnected;

- the female part has a receiving hole for straps, objects or part of clothing, said receiving hole being bordered by a flexible end edge, the thickness of which measured along the transverse axis is substantially constant;

Detailed description of the invention

In the remainder of the description, elements having an identical structure or similar functions will be designated by the same references.

In the remainder of the description, the longitudinal, transverse and vertical orientations indicated by the trihedron “X, Y, Z” of the figures will be adopted in a non-limiting manner - and without reference to terrestrial gravity. The trihedron defines the XY, XZ and YZ planes.

In the figures, there is shown a device 1 intended to ensure the connection of straps, objects or part of clothing (not shown in the drawings).

The device 1 comprises a male part 2 and a female part 3. Part 3 female has a reception area 4 intended to accommodate part 2 male. The male part 2 can thus be partially inserted into the female part 3. The male part 2 and the female part 3 are then integral. The mechanism making it possible to join the male and

female parts

2, 3 together will be described later.

Advantageously, the female part 3 is deformable. It has two mobile zones 5. A pressure oriented along the Z axis on these mobile areas 5 allows the male part 2 to be disengaged from the female part 3. Male part 2 is rigid. This means that the male part 2 does not deform during its insertion into the female part 3. Unlike known devices, a rigid male part 2, that is to say one which does not deform, gives the device 1 significantly improved mechanical strength.

The female part 3 comprises a body 6 which defines two lateral cavities 7. The lateral cavities 7 are distinct and separated from each other by a clearance 8. The clearance 8 arranged between the lateral cavities 7, advantageously allows the lateral cavities 7 to move closer to each other.

The male part 2 includes two side inserts 9. Each lateral insertion pin 9 is intended to be inserted into a lateral cavity 7, as can be seen in detail in Figures 3 and 4.

The body 6 of the female part 3 comprises an upper wall 10, a lower wall 11, an outer side wall 12 and an inner side wall 13. These

walls

10, 11, 12, 13 geometrically define the lateral cavities 7. As illustrated on When the male part 2 is inserted into the female part 3, the lateral insertion pins 9 come into contact with the inner side walls 13 of each lateral cavity 7 via an inlet edge 14.

As can be understood by observing the , when the male part 2 is inserted into the female part 3, each lateral insertion pin 9 comes into contact with the inner side wall 13 of each lateral cavity 7. As the male part 2 is inserted into the female part 3 and each lateral insertion pin 9 slides along an inner side wall 13, the lateral cavities 7 move closer to each other reducing the area of the clearance 8 space.

In the embodiments shown in the drawings, the female part 3 comprises two lateral uprights 27. The lateral uprights 27 extend substantially in a longitudinal direction of the device 1, in the extension of the lateral cavities 7. The side uprights 27 are interconnected by an end edge 18. The side uprights 27, the end edge 18 and the side cavities 7 together define a hole 17 for accommodating straps, objects or part of clothing.

1 ^erer embodiment

In the first embodiment illustrated in Figures 1 to 4, the end edge 18 has a substantially straight shape. Thus the end edge 18 does not or only slightly deform in the first embodiment. When the lateral cavities 7 move closer to (or move away from) each other, the lateral uprights 27 deform elastically. Insofar as the deformation of the lateral uprights 27 is in the elastic range, said lateral uprights 27 make it possible to return the lateral cavities 7 to the initial position after having been moved away from said initial position.

Advantageously, the lateral cavities 7 are interconnected by a secondary return spring 15. The secondary return spring 15 improves the return to the initial position of the lateral cavities 7. The initial position corresponds to the position of the lateral cavities 7 visible in the drawings.

The lateral cavities 7 extend from the inlet edge 14 through which the male part 2 is inserted to a distal end 16 where said lateral cavities 7 are interconnected by the first return spring 15. By positioning the secondary return spring 15 at this distal end 16, the latter does not extend into the displacement space 8, which makes it possible not to hinder the movement of the lateral cavities 7 while giving said space 8 of displacement. sufficient area.

Advantageously, the secondary return spring 15 is of substantially semi-circular shape. It thus has a concave shape, the concavity of which is turned towards the space 8 of travel. The semi-circular shape of the secondary return spring 15 has several advantages, it allows on the one hand to bypass the clearance 8 and on the other hand, in a small space, it gives sufficient stiffness to return the cavities 7 to the initial position lateral after deformation.

In order to lighten the device 1 according to the first embodiment, the female part 3 has material recesses 19.

According to a variant visible in Figures 8 and 9, it can be seen that the lateral locking notches 30 are narrowed along the Y axis. This advantageously allows better positioning of the male part 2 in the female part 3 and to avoid any residual play (rotation around the X axis) between part 2 male and part 3 female. Another difference, independent of the side locking notches 30, is that inner side grooves 23 are made in the inner side walls 13. These internal lateral grooves 23 open laterally, along the Z axis, into the clearance space on the one hand and into the lateral cavities 7 on the other hand. These internal lateral grooves 23 are offset from the entry edge 14 along the longitudinal X axis. The male part 2 thus penetrates more deeply into the female part 3, which improves the mechanical strength of the device 1.

According to an alternative embodiment, the lateral insertion pins 9 of the female part 3 are separated from one another by a constant distance D1. The distance D1 is measured between a vertex S1, S2 of a first insertion pin 9 and an outer edge B of the other insertion pin 9. These points S1, S2 are located at the tops of the lateral insertion pins 9.

According to an alternative embodiment, the lateral cavities 7 of the female part 3 are separated by an opening distance D2. This opening distance D2 varies when the lateral cavities 7 are set in motion by inserting the male part 2 into the female part. In what follows, the opening distance D2 is measured at rest, that is to say, when the male part 2 is not engaged inside the female part 3. The opening distance D2 is measured between an interior point E1 located on the top of the interior side wall 13 of a first lateral cavity 7 and a side end point E2 located on the exterior side wall 12 of the other. lateral cavity 7. Note that point E2 is located on the inner side of the outer side wall 12 of the side cavity 7. The fixed distance D1 is advantageously greater than or equal to the opening distance D2. In the embodiment shown in the drawings, the distance D1 is greater than the distance D2. This makes it possible to prevent one of the insertion pins 9 from entering the clearance space 8 when the male part 2 is inserted into the female part 3. This makes it possible to facilitate the blind insertion of the male part 2 into the female part 3. As can be seen on the , when the male part 2 is inserted into the female part 3 in an offset manner so that one of the insertion pins 9 abuts on the outer side wall 12 and more precisely at the level of the lateral locking notches 30, it is noted that the other insertion pin 9 is located, in the most unfavorable case, facing a lateral cavity 7 and not facing the clearance 8 space, thus forcing this lateral insertion pin 9 to enter the side cavity 7 by sliding along the inner side wall 13. This lateral insertion pin 9 therefore does not enter the clearance 8 space. This significantly improves the ergonomics of the device and allows an almost systematic effective looping.

In the embodiment shown in FIGS. 8 and 9, the male part 2 comprises lateral locking pins 29. More precisely, the male part 2 comprises two lateral locking pins 29. Each lateral locking pin 29 is arranged adjacent to a lateral insertion pin 9. The lateral locking pin 29 is located on the outside of the male part 2. The lateral locking pins 29 are in the form of projections which extend along the X axis.

The female part 2 has lateral locking notches 30. More precisely, the female part 2 comprises two lateral locking notches 30. A lateral locking notch 30 is made in each outer side wall 12. When the male part 2 is inserted into the female part 3, the lateral locking pins 29 are inserted into the lateral locking notches 30. The lateral locking pins 29 and the lateral locking notches 30 cooperate together improving the mechanical strength of the device. In particular, the lateral locking pins 29 and the lateral locking notches 30 together make it possible to inhibit any play according to a rotation of axis X. The width measured along the Y axis of the lateral locking notches 30 is advantageously less than one. width measured along the Y axis of the lateral insertion pins 9. Thus, when the lateral insertion pins 9 are located in front of the lateral locking notches 30, said lateral insertion pins 9 cannot enter the lateral locking notches 30. When a lateral insertion pin 9 abuts against the lateral locking notches 30, this lateral insertion pin 9 is oriented towards the lateral cavity 7, thus allowing easier looping.

According to an alternative embodiment, each inner side wall 13 comprises removals 31 of material so that the inner lateral grooves 23 are offset with respect to the inlet edge 14 along the longitudinal X axis of the device 1, said removals 31 of material allowing a deeper depression of the insertion pins 9 inside the lateral cavities 7.

A deeper penetration of the female part 3 into the male part 2 and a distance D1 greater than or equal to the distance D2 advantageously allow an almost systematic success of the insertion. This significantly improves the user experience.

2 ^èmeth embodiment

In the second embodiment illustrated in , the end edge 18 is deformable and has for this purpose a substantially curved shape. When the lateral cavities 7 approach (or move away) from one another, the lateral uprights 27 and the end edge 18 deform elastically. The deformation of the lateral uprights 27 and of the end edge 18 is in the elastic range and makes it possible to return the lateral cavities 7 to the initial position after having been moved away from said initial position.

Advantageously, the end edge 18 comprises a zone 28 of weakness. A thickness of the end edge at the level of this weakening zone 28 is measured substantially along the X axis and is less than a thickness of the end edge 18 measured along this same X axis outside the zone 28 of. weakening. On the , the weakening zone 28 has a substantially semi-circular shape. The weakening zone 28 advantageously makes it possible to make the end edge 18 more flexible.

The lateral cavities 7 are interconnected by a secondary return spring 15. The secondary return spring 15 improves the return to the initial position of the lateral cavities 7. The initial position corresponds to the position of the lateral cavities 7 visible in the drawings.

The combined forces of the secondary return spring 15 and of the end edge 18 advantageously make it possible to better hold the male part 2 and the female part 3 together, making the movement of the lateral cavities 7 more difficult. Another advantage is to allow a straight ejection of the part 2 male. Indeed, when a user presses on the mobile areas 5, the male part 2 is ejected with a greater initial speed.

The secondary return spring 15 of the second embodiment is identical to that of the first embodiment.

According to a variant visible on the , it can be seen that the lateral locking notches 30 are narrowed along the Y axis. This advantageously allows better positioning of the male part 2 in the female part 3 and to avoid any residual play (rotation around the X axis ) between part 2 male and part 3 female. Another difference, independent of the side locking notches 30, is that inner side grooves 23 are made in the inner side walls 13. These internal lateral grooves 23 open out laterally, along the Z axis, on the clearance space on the one hand and on the lateral cavities 7 on the other hand. These internal lateral grooves 23 are offset with respect to the entry edge 14 along the longitudinal X axis. The male part 2 thus penetrates more deeply into the female part 3, which improves the mechanical strength of the device 1.

According to an alternative embodiment, the lateral cavities 7 of the female part 3 are separated by an opening distance D2. This opening distance D2 varies when the lateral cavities 7 are set in motion by inserting the male part 2 into the female part. In what follows, the opening distance D2 is measured at rest, that is to say, when the male part 2 is not engaged inside the female part 3. The opening distance D2 is measured between an interior point E1 located on the top of the interior side wall 13 of a first lateral cavity 7 and a side end point E2 located on the exterior side wall 12 of the other cavity. 7 lateral and obtained by drawing a straight line D perpendicular to the axis X. Note that the point E2 is located on the inner side of the outer side wall 12 of the lateral cavity 7. The fixed distance D1 is advantageously greater than or equal to the opening distance D2. In the embodiment shown in the drawings, the distance D1 is greater than the distance D2. This makes it possible to prevent one of the insertion pins 9 from entering the clearance space 8 when the male part 2 is inserted into the female part 3. This makes it possible to facilitate the blind insertion of the male part 2 into the female part 3. As can be seen on the , when the male part 2 is inserted into the female part 3 in an offset manner so that one of the insertion pins 9 abuts on the outer side wall and more precisely at the level of the lateral locking notches 30, it is noted that the The other insertion pin 9 is located, in the most unfavorable case, facing a lateral cavity 7 and not facing the clearance 8 space, thus forcing this lateral insertion pin 9 to enter the cavity 7 side by sliding along the inner side wall 13. This lateral insertion pin 9 therefore does not enter the clearance 8 space. This significantly improves the ergonomics of the device and allows an almost systematic effective looping.

In the embodiment shown in , the male part 2 comprises side blocking pins 29. More precisely, the male part 2 comprises two lateral locking pins 29. Each lateral locking pin 29 is arranged adjacent to a lateral insertion pin. The lateral locking pin 29 is located on the outside of the male part 2. The lateral locking pins 29 are in the form of projections which extend along the X axis.

The female part 2 has lateral locking notches 30. More precisely, the female part 2 comprises two lateral locking notches 30. A lateral locking notch 30 is made in each outer side wall 12. When the male part 2 is inserted into the female part 3, the lateral locking pins 29 are inserted into the lateral locking notches 30. The lateral locking pins 29 and the lateral locking notches 30 cooperate together improving the mechanical strength of the device. In particular, the lateral locking pins 29 and the lateral locking notches 30 together make it possible to inhibit any play according to a rotation of axis X. The width measured along the Y axis of the lateral locking notches 30 is advantageously less than one. width measured along the Y axis of the lateral insertion pins 9. Thus, when the lateral insertion pins 9 are located opposite the pins of the lateral locking notches 30, said lateral insertion pins 9 cannot enter the lateral locking notches 30. When a lateral insertion pin 9 abuts against the lateral locking notches 30, this lateral insertion pin 9 is oriented towards the lateral cavity 7, thus allowing easier looping.

3 ^èmeth embodiment

In the third embodiment illustrated in , the end edge 18 is deformable and has for this purpose a substantially curved shape. When the lateral cavities 7 approach (or move away) from one another, the lateral uprights 27 and the end edge 18 deform elastically. The deformation of the lateral uprights 27 and of the end edge 18 is in the elastic range and makes it possible to return the lateral cavities 7 to the initial position after having been moved away from said initial position.

In this embodiment, the end edge 18 is devoid of a weakening zone. In addition, the lateral cavities 7 are not connected by a secondary return spring 15. Due to the fact that it does not include a weakening zone, the end edge 18 is made more rigid, which makes it possible to compensate for the non-presence of a secondary return spring 15 and to have identical properties to the first. and second embodiments.

According to an alternative embodiment, the lateral cavities 7 of the female part 3 are separated by an opening distance D2. This opening distance D2 varies when the lateral cavities 7 are set in motion by inserting the male part 2 into the female part. In what follows, the opening distance D2 is measured at rest, that is to say, when the male part 2 is not engaged inside the female part 3. The opening distance D2 is measured between an interior point E1 located on the top of the interior side wall 13 of a first lateral cavity 7 and a side end point E2 located on the exterior side wall 12 of the other cavity. 7 lateral and obtained by drawing a straight line D perpendicular to the axis X. Note that the point E2 is located on the inner side of the outer side wall 12 of the lateral cavity 7. The fixed distance D1 is advantageously greater than or equal to the opening distance D2. In the embodiment shown in the drawings, the distance D1 is greater than the distance D2. This makes it possible to prevent one of the insertion pins 9 from entering the clearance space 8 when the male part 2 is inserted into the female part 3. This makes it possible to facilitate the blind insertion of the male part 2 into the female part 3. As can be seen on the , when the male part 2 is inserted into the female part 3 in an offset manner so that one of the insertion pins 9 abuts on the outer side wall 12 and more precisely at the level of the lateral locking notches 30, it is noted that the other insertion pin 9 is located, in the most unfavorable case, facing a lateral cavity 7 and not facing the clearance 8 space, thus forcing this lateral insertion pin 9 to enter the side cavity 7 by sliding along the inner side wall 13. This lateral insertion pin 9 therefore does not enter the clearance 8 space. This significantly improves the ergonomics of the device and allows an almost systematic effective looping.

4 ^èmeth embodiment

In the fourth embodiment illustrated in , the end edge 18 is deformable and has for this purpose a substantially curved shape. When the lateral cavities 7 approach (or move away) from one another, the lateral uprights 27 and the end edge 18 deform elastically. The deformation of the lateral uprights 27 and of the end edge 18 is in the elastic range and makes it possible to return the lateral cavities 7 to the initial position after having been moved away from said initial position.

The secondary return spring 15 of the fourth embodiment differs from that of the first and second embodiments in that it has a more flared shape and a different shape. In the fourth embodiment, the secondary return spring 15 has a substantially triangular shape, one apex of which is open onto the space 8 of movement.

According to a variant visible in FIGS. 12, it can be seen that the lateral locking notches 30 are narrowed along the Y axis. This advantageously allows better positioning of the male part 2 in the female part 3 and to avoid any residual play. (rotation around the X axis) between part 2 male and part 3 female. Another difference, independent of the side locking notches 30, is that inner side grooves 23 are made in the inner side walls 13. These internal lateral grooves 23 open laterally, along the Z axis, into the clearance space on the one hand and into the lateral cavities 7 on the other hand. These internal lateral grooves 23 are offset from the entry edge 14 along the longitudinal X axis. The male part 2 thus penetrates more deeply into the female part 3, which improves the mechanical strength of the device 1.

The characteristics which will be described in the following apply to all the embodiments.

It is also possible to provide lateral projections 20 in the receiving hole 17. These lateral projections 20 oriented along the Y axis, allow straps and clothing to be attached. They can be arranged in all the embodiments, but are visible in the drawings only in the first embodiment. In order to allow the displacement of the lateral cavities 7, the lateral projections 20 are separated from one another by a second clearance 21 space.

The male part 2 advantageously comprises a wall 22 for stiffening. The stiffening wall 22 connects the lateral insertion pins 9 together. The stiffening wall 22 makes it possible to keep the lateral insertion pins 9 immobile at all times and particularly during insertion into the lateral cavities 7 of the female part 3. By remaining stationary, that is to say by keeping the distance which separates the lateral insertion pins 9 constant, the lateral cavities 7 can come closer to each other during the insertion of the part 2 male in part 3 female. Otherwise, that is to say if the lateral insertion pins 9 were deformable, the movement of the lateral cavities 7 could not be done correctly.

Each side cavity 7 has a groove 23 made in the inner side wall 13. The grooves 23 allow the passage of the stiffening wall 22 in the female part 3.

Each lateral insertion pin 9 comprises a hook 24. Each lateral cavity 7 comprises an attachment zone 25 in the form of a reservation made in the inner side wall 13. The shape of the reservation is substantially a counter-impression of the hook 24. The hook 24 makes it possible to secure the male part 2 and the female part 3. The attachment zone 25 is advantageously arranged in the inner side wall 13 in order to concentrate the forces at the center of the device 1. This gives the device 1 good resistance to mechanical stresses. It should also be noted that the arrangement of the attachment zones 25, under a tensile force, implies that the lateral cavities 7 tend to move away from one another, which gives the device a better hold. mechanical.

In order to allow the passage of the stiffening wall 22, the groove 23 extends laterally from the reception area 4 to the clearance space 8 and longitudinally from the entry edge 14 over a distance allowing the hooks 24 of the lateral insertion pins 9 reach the attachment zones 25.

Advantageously, the female part 3 comprises lights 26 connecting the reception hole to the reception area 4 located inside the side cavities 7. These slots 26 make it possible to remove a foreign body from the female part 3 and which would prevent the joining of the male part and the female part.

During the insertion of the male part 2 into the female part 3, the hooks 24 move along the inner side wall 13 and in contact with the latter. The lateral cavities 7 move closer to each other, as the male part 2 progresses in the female part 3. When the hooks 24 reach the level of the hooking zones 25, they engage inside the reservations and the lateral cavities 7 are immediately forcefully returned to the initial position. The male part 2 and the female part 3 are then integral. In order to separate the male and

female parts

2, 3, a user presses on the outer side walls 12 of the female part 3, which brings the lateral cavities 7 closer to each other by reducing the surface area of the space 8 of travel. With the distance between the side insert pins 9 remaining constant, the hooks 24 exit the hooking areas 25 and slide along the inner side wall 13. There then occurs an ejection of the male part 2. This is due to a sudden release of the stresses which occurs the instant the hooks 24 exit the catch zones 25.
