Description

DESCRIPTION

Retractable bristle brush

The present invention relates to a hairbrush. More specifically to a brush with retractable bristles.

Hair is a very important factor in personal image. One of the best known hair care products are brushes. The number of designs, embodiments or variants of hairbrushes is very high. Despite this, similarities can be found in most of them. Hairbrushes usually comprise a main body with a handle or handle to facilitate gripping and a head with protruding bristles from said head. Unlike a comb, the bristles do not project in a line, but are projected evenly across a surface, resulting in a larger brushing surface.

One of the drawbacks of most hairbrushes is that, precisely because of said configuration of bristles distributed along a surface, they occupy a considerable volume. This makes them less suitable for storing in small spaces, such as a drawer or a toiletry bag. Another drawback is that since the spikes are exposed and projected, it is much easier for them to break when they come into contact with other elements. Another drawback of most hairbrushes is that the hair tends to get tangled between the bristles and its cleaning is difficult.

In the state of the art, you can see how some hairbrushes have been developed that try to deal with some of these drawbacks.

Document ES1205236U discloses a brush with concealable bristles that has a body divided into two main parts joined together and a mobile interior plate in which the bristles are located and that includes a handle on the side of the plate opposite to the one on which spikes are located. The handle allows you to move the plate and thus hide the spikes inside the body. Despite the fact that the bristles of the document ES1205236U can be hidden, their configuration means that, in the hidden bristle position, the handle protrudes from the body on the opposite side of the bristles, so the design is not optimal for favor the storage of the brush.

The document ES1172858U discloses a brush with bristles that can be hidden for the most part. As mentioned and shown in the document, the ends of the prongs always protrude, at least partially, from the main body. The brush of document ES1772858U has a button on the opposite side of the bristles. In a similar way to document ES1205236U, said button can be flush, or protrude depending on the position in which the spikes are found. The drawbacks of the brushes in both documents are that the aesthetics of the brush is different from that of conventional brushes without retractable bristles and that it is difficult to move from the use position to the storage position, in which the bristles are retracted.

It is an object of the present invention to provide a hairbrush that does not have the aforementioned drawbacks.

More particularly, the present invention provides a hairbrush comprising an outer main body which in turn comprises a handle and a head. Said brush also comprises an inner plate with spikes capable of movement inside the outer body in the direction of the spikes and elastic means for extracting the plate. The inner plate is movable along a path in the longitudinal direction of the tines between a use position in which the tines protrude from the head and a storage position in which the tines are inserted into the body. To this end, the head comprises a wall with holes that allow the passage of the aforementioned spikes in their movement between the storage position and the use position. The brush also includes fixing means for the inner plate that comprise at least one operable part that stands in the path of the plate, in such a way that, when said operable part stands in the path, it prevents the passage of the brush. plate from the use position to the storage position and vice versa. Preferably, said actuatable part can pivot with respect to an axis between a fixing position in which a part of the actuatable part is interposed in the trajectory of the plate, preventing the movement of said plate along said trajectory, and a plate release position in which the actuatable part does not get in the way.

Having a movable inner plate with the tines in combination with holes for the passage of the tines allows the tines to be completely hidden or retracted within the main body, which is preferable. This allows the brush to be much more compact in its storage position, and therefore occupies less space when stored and, in turn, is more robust, against blows or any other effort, by not protruding the spikes, or any other mobile part, with respect to the body. On the other hand, the fixing means of the plate make it possible to fix the plate in its position of use and thus the brush can be used normally in said position of use. By getting in the way, the fixing means make it possible to lock both the storage position and the use position, without interfering with the ease of moving from one position to another and, moreover, they allow independent actuation that is more comfortable for the user. On the other hand, having a part that can be operated with respect to an axis between a fixing position and a release position allows said part to present a very simple but effective fixing effect, interposing and/or moving away from the path of movement of the plate. in a very convenient way.

Preferably, the actuatable part has elastic means that push the part towards the fixing position or towards the release position. In this way, the operable part, automatically and without user intervention, tends to be placed in a default position. More preferably, the elastic means that act on the actuatable part push the part to the fixing position. In this way, the actuatable part is automatically placed in the fixing position, blocking the brush in the position - of use or storage - in which it is found, and therefore preventing it from going from one position to another. another accidentally.

Preferably, the brush includes elastic means that act on the plate to move it from the storage position to the use position or vice versa. The elastic means cause the brush to automatically move to the use or storage position, which in turn allows the actuation of the fixing means to cause the automatic change of the position of the brush to the position towards which the fingers push. elastic means of the plate. More preferably, the elastic means of the plate pushes the plate towards the position of use.

Preferably, in the fixing position, the actuatable part leaves a first space between the wall with holes in the head and said actuatable part such that it allows the plate to be housed in said space, without allowing the plate to move when it is in position. the position of use.

Likewise preferably, in the fixing position, the actuatable part leaves a second space between the actuatable part and a wall of the head opposite the wall with holes such that it prevents movement of the plate in the storage position.

The fact that the clearance enters the wall with holes and said at least one operable part when said at least one operable part is in the fixing position is just enough to accommodate the plate, allows said plate to be fixed in such a way that it can be used the brush with the bristles removed as normal, without any unwanted movement of the plate or bristles that could cause discomfort.

On the other hand, if the clearance is just enough so that the plate is also fixed between said at least one actuatable part and the wall opposite the wall with holes, that is to say the back or rear wall of the brush head, the pins can be permanently hidden when the plate is fixed in its storage position. This helps the plate not rattle or move inside the main body despite the brush being moved.

In a preferred embodiment, said at least one actuatable part has an actuation surface that is exposed externally on one side of the main body, in such a way that said surface forms part of the outline of the body in such a way that a user can actuate the part by pressing on a point of said drive surface.

The fact that the actuatable part itself has an exposed surface means that the actuatable part that fixes or releases the movement of the plate is the same one on which the actuation is applied. This avoids the use of unnecessary parts or components in the mechanism, which makes it simpler. A greater simplicity of the mechanism makes it easier to assemble and may even reduce its cost. On the other hand, the fact that the drive surface is on the side of the body makes the brush more ergonomic, since the drive surface is within easy reach of the user's fingers even during use.

Preferably, the elastic means of the actuatable part are arranged in such a way that they exert an action contrary to that of the actuation caused by pressure on the actuation surface.

In a preferred embodiment, said at least one part comprises an orifice to receive an axis belonging to the main body on which said at least one piece pivots.

The axis about which the actuatable part can pivot can be a physical axis, which is developed from a structure proper to the main body. On the other hand, the same piece can comprise a hole in which said physical axis is inserted, in order to achieve a rotation with respect to said axis. Both of these features, in a similar way to what was mentioned above, contribute, separately and in combination, to facilitating the configuration and design of the mechanism.

In a preferred embodiment, said at least one pivoting part comprises clipping means to fix said at least one part both in the fixing position and/or in the release position.

The fact of comprising clipping means for fixing the part in any of its positions helps to improve the operation of the invention, fixing the pivoting part in one of its positions, or in both, so that the part does not change its position from involuntary way. An involuntary change in the position of the part would result in the release or fixing of the plate inadvertently, which would hinder the user's ability to decide when to release or fix the plate, and therefore could worsen their experience.

In a preferred embodiment, it comprises stops that limit the rotation of the actuatable part between the fixing position and the release position.

In a preferred embodiment, the main body includes guides inside it to guide said movement of the plate between the use position and the storage position.

Especially preferably, the inner plate can comprise a push button to allow the user to push the plate from the use position towards the storage position. More preferably, said button can be an area devoid of spikes on the plate. Even more preferably, said zone can be arranged centrally with respect to the plate. Even more preferably, said central zone can comprise a projection that protrudes from the body of the brush in the position of use. Said protrusion facilitates the pushing action by the user. Advantageously, the brush head has an orifice that allows the push button to pass through. This allows access to the button by the user.

The figures show an exemplary embodiment of a brush 1 according to the present invention.

As can be seen in figure 1, the brush externally has a main body 10 with a head 11 and a handle 12. The main body 10 has an external casing made up of a front part 101 and a back part 102. The bristles 141 of the brush 1 can be seen distributed along the front surface of the head 11. The pins 141 come from inside the brush and go through holes arranged in a wall 15 with holes arranged in the head 11, and more specifically in the head part of the part. frontal 101. In the center of the distribution of bristles 141, the example shown has a button 142. On the sides of the main body 10, the brush has two operable parts 16 that allow the output of the bristles to be activated from inside the main body to the position observed in figure 1.

Figure 2 shows the brush of figure 1, with the bristles in the storage position. In the stowed position, the tines are not visible.

Figures 3 to 10 allow to see different internal and external elements of the brush 1 of the example. Figures 3 and 4 show the different elements. Figures 5 to 7 are individual sections that allow the relative position of the different elements to be seen in the use position and with the actuatable parts in the fixing position. Figures 8 and 9 are respective sections that allow observing the relative position of the different elements in the storage position. For illustrative purposes, figure 9 shows the actuatable part in the release position. On the other hand, figure 9 is a detailed view of the elastic means of the actuatable parts and an example of a device for clipping them.

Referring to the figures, it can be seen that the pins 141 are arranged occupying the surface of a plate 14 located inside the brush 1. In the center of the plate, the button 142 is arranged, the purpose of which is to make it easier for the user to press the plate to pass from the use position, shown in figure 1, to the storage position shown in figure 2. The plate has elastic means that push it towards the use position. In the example shown, the elastic means comprise springs 18a, 18b, 18c, 18d that are housed in corresponding housings 121 of the back piece 102. The front piece 101 also has guides 113, 114 that guide the movement of the plate 14 from the storage position, in which the plate is located at the bottom of the brush, close to or touching the main wall 15b of the back piece 102, to the use position, in which the plate is located in the front or upper part of the brush. brush, next to or touching the wall 15a with holes for the teeth located in the front part of the brush. For guiding, the plate 14 comprises through holes 113', 114' conjugated with the guides 113, 114. The elastic means of the example ensure that, in the absence of any other action, the tines 141 are permanently pushed towards the position of use, that is, protruding from the head 11 of the brush, as shown in figure 1.

The example shown presents two operable parts 16 that act in unison and whose function is to block or release the movement of the plate from the storage position to the use position and/or vice versa. For this, the actuatable parts 16 are mobile, in such a way that they present a fixing position, in which they perform the aforementioned blocking of the movement of the plate 14, and a release position in which the parts release the trajectory of the plate between them. the position of use and that of storage, or vice versa. In the case of the example, both actuatable parts 16 are pivotable around the corresponding axes 122, 122'. The rotational movement around the corresponding axis 122, 122' causes the corresponding interposition end 131 of each of the pieces 16 to stand in the path of the plate 14. In the example shown, both pieces share an elastic means, in Specifically, a spring 17, whose action causes the rotation of both actuatable parts 16 until the interposition ends 131 are located in the trajectory of the plate, in such a way that the parts are located in said fixing position. The spring 17 is placed compressed between the two operable parts 16 and guided by lugs 133 of each one of the corresponding operable parts 16. Said lugs 133 are arranged opposite each other. Both driveable parts 16 are symmetrical to each other, so they move in unison with each other, as if they were one. In the example shown, the axes 122, 122' around which the actuatable parts 16 move belong to the back part 102 of the brush, each part having respective holes 132 to receive said axes 122, 122'. Alternatively, the axes could belong to the front part 101. Also alternatively, said axes could be part of the actuatable parts 16 and be housed in corresponding holes in any of the parts that make up the outer casing of the brush.

When the parts 16 are located in the fixing position, they prevent the movement of the plate 14, in such a way that it will remain in the position in which it is (storage or extracted position). In particular, the interposing ends 131 are interposed in the trajectory of the plate 14, as seen in figures 6 and 7. When the parts are placed in the release position, the interposing ends 131 are housed in a space of the interior of the brush in which they do not interfere with said trajectory, as has been represented in figure 9. It should be noted that, in the example, the actuatable parts can be in the release or fixing position interchangeably, both with the plate and the tines in the use position and with the plate and the tines in the storage position.

In the example, given that the spring 17 pushes the actuatable parts 16 -and in particular their interposition ends 131- towards the fixing position, said parts will prevent the passage from the position of use to that of storage, and vice versa, in the absence of from an external action by the user.

Said action can be carried out by the user by pressing the actuatable parts 16 on their corresponding actuating surfaces 161. Said drive surfaces 161 are located on the outside of the side of brush 1. When pressed, an action is exerted contrary to that of spring 17 and tends to bring the interposition ends out of the trajectory of plate 14. To avoid drives Accidental accidents of the brush, each actuatable part 16 has a tab 134 that is conjugated with a clipping recess 151, which dimensionally interfere with each other. Said interference makes it necessary to exert a minimum force on the actuatable part for it to start its movement. This feature associated with the tabs 134 is entirely optional. This feature can also be implemented in two different ways. According to a first embodiment, the spring exerts a force sufficient to overcome the force necessary for each of the tabs 134 to overcome the corresponding clipping recess 151, in such a way that, when the user stops pressing the actuation surfaces 161 , the actuatable part 16 automatically returns to the fixing position. According to a second way, the spring does not exert a sufficient force for the tabs 134 to overcome the corresponding recesses of the clipping 151. In this case, the user must exert an opposite actuation by pressing the actuation parts by the outer end furthest from the surfaces drive 161, which in the figures of the example is the end closest to the head. The first embodiment is preferred.

The operation of brush 1 in the example is described below.

Starting from the position of use shown in figure 1, and with the actuatable parts in the release position, the user can put the brush in the storage position if he presses the plate 14 through the button 142, with sufficient force to beat the action of the elastic means of the plate (springs 18a, 18b, 18c, 18d). When the board reaches the stowed position, in the case of the example shown, the user must release pressure on the actuatable parts, which causes the interposing ends to move into the clamping position and prevents movement of the board. The brush will thus remain in the storage position.

In order to move the brush from the storage position to the use position, the user must keep the actuatable parts depressed by their actuation surfaces 161 furthest from the head. This causes the interposer ends 131 to withdraw and clear the path of the plate between the storage position and the use position. The springs 18a, 18b, 18c, 18d push the plate and this causes the pins to come out through the corresponding holes in the wall 15a with holes in the brush 1. Likewise, the button 142 also emerges out through the hole 112 corresponding. When the actuating parts 16 are released from depressing, the spring 17 returns them to the fixing position, which fixes the brush in the position of use. The brush is now ready for use.

Although the invention has been presented and described with reference to its embodiments, it will be understood that these are not limiting of the invention, and therefore multiple constructive details or others could be variables that may become evident to technicians in the sector after interpret the matter disclosed in the present description, claims and drawings. In particular, in principle, all the features of each of the different embodiments and alternatives shown and/or suggested are combinable with each other.
