Definitions
- the present invention relates to a device for guiding the slider of a zipper to facilitate the action of the slider in its movement when it fits the teeth of the zipper or separates them.
- the cursor is equipped with two grooves that meet to guide the teeth when sliding the cursor on the closure.
- the zippers are placed on relatively flexible textile supports, so deformable. Because of this deformation, the teeth of the zippers may be in front of the cursor in a plane that blocks or slows the cursor's progress. The user must pull the zipper with one hand and with his other hand hold the fabric to optimize the movement of the cursor.
- the use of both hands to open or close a zipper may be problematic for persons with disabilities or persons whose dexterity of hands has been diminished on an ad hoc basis, for example when using large ski gloves or gloves. motorcycle, which do not allow a good pre-emption of the zipper.
- the device according to the invention overcomes this disadvantage. It comprises in fact according to a first characteristic a guide secured to the slider of a zipper.
- This guide is positioned under the cursor.
- the guide consists of two pads located a few centimeters in front of the cursor axis and two pads located a few centimeters behind the cursor axis.
- the guide has two skates on his left and two skates on his right.
- the pads slide in rails secured to the support of the zipper.
- the two pads on the left of the guide slide in the same rail, the one to the left of the cursor.
- the two pads located on the right of the guide slide in the same rail, the one located to the right of the cursor.
- the guide secured to the cursor can also be secured to a chain. On one side of the guide, one end of the chain will be attached to one of the front pads and the other end to one of the rear pads of the guide. The other two skates of the guide will let the chain pass freely.
- the path of the chain is thus the following, fixed at one of its ends on one of the guide's pads, it travels along the rail, leaves the rail to reach a toothed pulley, leaves in the second rail, travels the along this rail, out of the rail and arrives on a second toothed pulley, enters the first rail where it is fixed by its other end to the second shoe guide.
- the chain is therefore integral with the cursor and follows its movements.
- the chain is held in place by the extrusion profile of the rails, which allows both to slide the chain and slide the skates of the guide.
- the chain is kept under tension by two toothed pulleys which are integral with the fabric of the product.
- the cursor is therefore secured to the movements of the chain.
- one of the toothed pulleys can be associated with a drive system which under the control of the user via a button, will rotate this toothed pulley, which will drive the chain and the second toothed pulley and move the guide secured to the cursor.
- the zipper can thus close without having to use the slider associated with the slider, automatically by actuating the drive device with the help of a button.
- the drive system may be mechanical, with a spiral spring for example or assisted electrically.
- the guide may have one or more axial pivots located between the axis of the guide and the front and rear ends of the guide, near the pads.
- pivots have the function of facilitating the stroke of the guide, during its passage in the curves of the product, allowing a travel on the vertical axis.
- the pivots allow the pads to follow the different angles inherent in the curves of the product, as for a trolley case or "trolley" which generally has four rounded corners.
- the device of the invention can be equipped with two guides for one and the same zipper.
- These two guides associated with the sliders will be installed so as to be face to face, in symmetry or mirror mode and side by side when the zipper is in the closed position.
- the first guide is attached to the chain on one side of the rail
- the second guide is also attached to the chain but on the side opposite the first guide.
- the other guide itself associated with the chain moves, by mechanical drive effect, in the opposite direction to the first guide. This makes it possible to operate only one of the two guides and to close or open the zipper by halving the distance to be traveled, relative to the total length of the zipper.
- the user of the device of the invention manually actuates the guide, only half of the zipper, but because of the double guide, the zipper opens or closes in its entirety.
- the user can thus close or open two times faster a zipper equipped with two guides that a zipper equipped with a single guide.
- the rails secured to the support of the slide fastener may each be divided into the length in two distinct parts, so that these two distinct parts can fit or slide one in the other.
- the division into two distinct parts of the two rails of the device of the invention will be made so as to have an upper portion secured to the support of the zipper and a lower portion secured to the fabric of the product. This allows in case of breakage of one of the teeth of the zipper to replace the upper part of the rail, while leaving the lower part on the product.
- the rails of the device of the invention may have a particular extrusion profile in order to have a stop located just below the teeth of the zipper.
- a downward pressure is exerted on the teeth of the zipper, for example with the aid of a sharp object such as a ballpoint pen, the teeth will sink and abut on this part of the rails of the device of the invention.
- the fact of pressing the teeth of the zipper with a pointed object has the effect of giving angle to the teeth and decreasing the quality of the interlocking of the teeth between them.
- the abutment induced by the extrusion profile of the rails makes it possible to reduce the value of this angle and decreases the risk of disarticulation of the teeth.
- Figure 1 shows a top view of the device of the invention with the fabric of the product when the zipper is not completely closed and the entire device undergoes deformation.
- Figure 2 shows in top view, the device of the invention without the fabric of the product when the zipper is not completely closed.
- Figure 3 shows a top view of the device of the invention without the support of the zipper when the zipper is not completely closed.
- Figure 4 shows a top view of the device of the invention without the rails when the zipper is not completely closed.
- Figure 5 shows in a view from below, the device of the invention without the rails when the zipper is not completely closed and shows the guide positioned just below the cursor.
- Figure 6 shows in top view, the device of the invention without the fabric of the product and without the support of the zipper when the zipper is closed.
- Figure 7 shows a top view of the device of the invention without the rails when the zipper is closed.
- Figure 8 shows a view from below, the device of the invention without the rails when the zipper is closed and shows the guide positioned just below the slider.
- Figure 9 shows a perspective view, an exploded of all the elements of the device of the invention.
- Figure 10 shows a close perspective view, the slider and the zipper puller with the guide, secured to the slider, which slides in the rails.
- Figure 11 shows a close perspective view, the slider of the zipper positioned and secured to the guide with its four pads.
- Figure 12 shows a close perspective view, left side in the direction of closure, the slider of the zipper secured to the guide with its four pads.
- 13 shows a close perspective view, the slider of the zipper secured to the guide with its four pads, two pads are secured to the chain and the other two let the chain freely.
- Figure 14 shows a close perspective view, an embodiment of the device of the invention, with two axial pivots located between the axis of the guide and the front and rear ends of the guide, where are located the pads. These pivots will facilitate the stroke of the guide and the slider associated with it, during passages in the curved portions of the product.
- FIG. 15 is a close-up perspective view of one embodiment of the device of the invention equipped with two guides. These two guides associated with the sliders are installed so as to be face to face, in symmetry or mirror mode and side by side when the zipper is in the closed position. By operating one of the two guides, the other guide secured to the chain moves, by mechanical drive effect, in the opposite direction to the first guide also secured to the chain.
- FIG. 16 is a close-up perspective view of an embodiment of the device of the invention, in which the rails secured to the support of the slide fastener are divided into two distinct parts capable of sliding one into the other.
- the division of the two rails of the device of the invention allows to have an upper portion secured to the support of the zipper and a lower portion secured to the fabric of the product.
- the upper part of the rail is sliding in the lower part of the rail.
- This figure also shows that the extrusion profile of the rails, at the bottom, makes it possible to create a stop to reduce the risk of loosening of the teeth of the zipper, when pressure is exerted downwards, on the teeth. of the zipper.
- the two rails of the device of the invention has been shown in this figure.
- FIG. 17 is a side view of an embodiment of the device of the invention, in which the rails secured to the support of the slide fastener are divided into two distinct parts capable of sliding one into the other.
- the division of the two rails of the device of the invention makes it possible to have an upper part secured to the support of the zipper and a lower part secured to the fabric of the product.
- This figure also shows that the extrusion profile of the rails, at the bottom, makes it possible to create a stop to reduce the risk of loosening of the teeth of the zipper, when pressure is exerted downwards, on the teeth. of the zipper. For reasons of readability only one of the two rails of the device of the invention has been shown in this figure.
- the device comprises a guide (2) secured to the slider (1) of a zipper.
- This guide (2) is positioned under the cursor (1).
- the guide (2) consists of two pads (3a, 3b) located a few centimeters in front of the axis of the cursor (1) and two pads (3c, 3d) located a few centimeters at the rear of the cursor axis (1).
- the pads (3a, 3b, 3c, 3d) slide in rails (4, 5) secured to the support (12) of the zipper.
- the guide (2) keeps on the same plane the cursor (1) and the teeth (6) closest to the slider (1) of the zipper. This eases the action of the slider (1) by presenting the teeth (6) of the zipper on a plane adapted to its action.
- the guide (2) secured to the slider (1), may also be secured to a chain (7).
- one end of the chain (7) will be attached to one of the front pads (3a) and the other end of the chain (7) to one of the rear pads (3c) of the guide ( 2).
- the two other pads (3b, 3d) of the guide (2) will let the chain (7) pass freely.
- the path of the chain (7) is therefore the following, fixed at one of its ends on one of the pads (3a) of the guide (2), it travels along the rail (5), leaves the rail (5) to reach a toothed pulley (9), leaves in the second rail (4), travels along this rail (4), leaves the rail (4) and arrives on a second toothed pulley (8), enters the first rail (5) where it is fixed at its other end to the second pad (3c) of the guide (2).
- the chain (7) is integral with the cursor (1) and follows its movements.
- the chain (7) is held in place by the extrusion profile rails (4, 5), which allows both to slide the chain (7) and slide the guide (2).
- the chain (7) is held under tension by two toothed pulleys (8, 9) which are integral with the fabric of the product (14).
- the slider (1) can therefore be driven by the chain (7).
- one of the toothed pulleys (9) can be associated with a drive system (10) which under the control of the user via a button (11), will rotate this toothed pulley (9), which will cause the chain (7) and the second toothed pulley (8) and move the guide (2) secured to the slider (1).
- the zipper can thus close without having to use the pull tab (13) associated with the slider (1), automatically by actuating the drive system (10) with the help of the button (11).
- the drive system (10) may be mechanical, with a spiral spring for example, or assisted electrically.
- the device according to the invention is particularly intended for zippers for backpacks.
- the user of a backpack equipped with the device of the invention could thus close with the help of a button one or more pockets of his backpack.
- a button one or more pockets of his backpack.
- It also allows persons with disabilities or persons whose dexterity has been reduced on an occasional basis, for example by wearing ski or motorcycle gloves, to close and open easily a zipper of a single hand, by pressing one or more buttons.
