Description

  The present invention relates to a gas operated hair styling device including a handle and a styling rod connected to the handle.

background

  A hair styling device comprising a styling rod for shaping (especially straightening, curling and waving), where the hairs face each other between the tongs and the tongs are open and closed Such styling devices are known in the prior art that can be transferred between the two. For example, WO 2004/019723 shows a gas-operated hair styling device of the type described above having a replaceable gas cartridge in the handle of the hair styling device.

  In this case, the gas cartridge housing is closed by a removable closure cap, which is removed from the handle when the cartridge is replaced (ie, the cartridge must be removed from the handle). . To remove the empty gas cartridge, the user must manually remove the gas cartridge from the needle valve in order to remove it from the handle housing. In order to insert a new gas filling cartridge, it is necessary to manually attach the cartridge to a needle valve provided for degassing. Finally, before use, the user must close the handle with a closure cap.

  The exchange process has drawbacks in terms of user friendliness and ease of handling. Because the user has to handle several parts (ie handle, closure cap), the user must ensure that the closure cap is again accurately and in a specific direction with the handle. Because it must.

  In particular, in one embodiment, the closure cap is positioned at the end of the handle and is configured to be removed from the handle by a snap mechanism so that the cartridge must be replaced while the hair styling device is in use. Increased risk of damage. In such an implementation, safe handling of the handle is possible only in a very limited way after the closure cap has been removed. In particular, the process of separating the closure cap can cause the handle to slip off, so that the user's hand may touch the hot styling rod.

  Furthermore, the removable closure requires a double wall configuration of the handle that provides, at least in part, the guidance length and the space required for entrance guidance. In particular, with respect to portable hair styling devices configured to reduce component size and weight, at least partially double wall handle embodiments are inherently disadvantageous. Furthermore, the separable connection between the handle of the hair styling device and the removable closure cap usually causes the user the impression of handling a more unstable device.

  Therefore, there is a need for a hair styling device that improves the handling of the device when replacing the gas cartridge.

Summary of the Invention

  According to one aspect of the invention, a hair styling device includes a styling rod and a handle coupled to the styling rod. The handle is configured to receive a gas cartridge and is characterized by a retaining device and a pivoting cap for closing the gas cartridge housing. The pivot cap is connected to the holding device and can pivot between an open position and a closed position.

  The pivoting cap prevents the user of the hair styling device from having to handle several components of the hair styling device if the gas cartridge has to be replaced. The pivoting cap is constructed as an integral part of the handle of the hair styling device, so that during the process of changing the gas cartridge, the removable closure part is for example misplaced, damaged and incorrectly connected to the handle Obtaining is effectively avoided. Since the closure cap no longer needs to be separated to change the cartridge, it is also possible for the user to avoid burning by touching the hot styling rod.

  Typically, the pivot cap is rotatable about a fixed pivot axis to prevent accidental closure of the housing.

  Furthermore, the closure cap allows for a holding device according to a single wall embodiment, which holding device considerably reduces the size of the holding device when compared to devices according to the prior art.

  In some embodiments of the invention, the hair styling device includes snap engagement means to secure the cap in the open position. For example, when the user transitions or pivots the cap from the closed position to the open position, the snap engagement mechanism causes the cap to stop or lock in the open position. In the open position, the housing for the gas cartridge is particularly easily accessed and the cap is automatically switched to the closed position during the gas cartridge removal or insertion process in that the cap is secured in the open position. To prevent. Therefore, sticking in the open position considerably increases the ease of handling and user friendliness of the hair styling device during the process of changing the gas cartridge.

  In some embodiments of the present invention, the gas cartridge can be inserted into the housing of the holding device, but can enter the operating position during the process of axially closing towards the styling rod in the longitudinal direction of the device. Is possible. In the operating position, the gas cartridge is pushed over a pin or needle valve to extract gas from the cartridge. Therefore, the gas cartridge housing allows the axial movement of the gas cartridge between the operating position and the removal position. In the removal position, the gas cartridge is usually separated from the pin or needle valve and removed directly from the housing. Compared to the removal position, in the operating position the cartridge is moved towards the styling rod. On the other hand, the removal position is arranged far away from the styling rod.

  In some embodiments of the present invention, the interior of the cap is characterized by contact parts in its free end region that exert a displacement force on the gas cartridge in the direction of the styling rod when the cap is closed. Make it work. The free end of the cap is the end opposite to the pivot axis. The contact parts can be configured, for example, as square surfaces, which can switch radial or normal forces to axial or horizontal displacement forces, so that the displacement forces act on the gas cartridge. The gas cartridge is moved in the direction of the styling rod until it reaches the operating position.

  The associated switching between the contact part and the force acting on the cap achieves that, just with the closure of the cap, the gas cartridge is automatically pushed onto the pin or needle valve to extract the gas. This eliminates the need to manually push the gas cartridge with the pin of the needle valve as configured in the prior art.

  In some embodiments of the present invention, the cap has a protrusion in its interior in the link area to the holding device. The protrusion is configured to apply a displacement force to the gas cartridge away from the styling rod when the cap is opened. The projection is spaced from the pivot axis and is arranged to form a rigid portion with the cap. As a result, when opening the cap, the protrusion attaches to the gas cartridge, which instead is automatically pulled from the pin or needle valve.

  These embodiments include further improvements to the hair styling device. This is because it is no longer necessary to manually remove or pull the gas cartridge from the pin or needle valve as compared with the prior art. Thus, after the cap is opened, especially after the cap is secured in the open position, the used cartridge is removed from the pin and not attached to the housing, so that the user is user-friendly and easy This is particularly advantageous in that the gas cartridge can be removed from the housing.

  According to a further embodiment of the invention, the holding device is characterized by an opening mechanism that lifts the cap from the closed position to the released position. In the closed position of the cap, the cap and the holding device are usually attached to each other in the same plane, so that it is possible to lift the cap from the closed position only to a limited extent, for example due to a smooth surface structure. . However, in the released position, the cap forms at least a gap between the cap and the holding device, which makes it much easier to remove or lift the cap. Furthermore, the opening mechanism serves the purpose of automatically lifting the free end of the cap from the closed position to the released position.

  In some embodiments of the invention, the interior of the cap is characterized by at least one spring-loaded element for lifting the cap from the closed position. For example, when the cap is closed, the spring-loaded element can be tensioned and the spring energy stored in the spring-loaded element can lift the cap to the released position when the cap is opened or stuck. To. Thus, the spring-loaded element is tensioned against the gas cartridge, for example when the cap is closed.

  In some embodiments of the invention, the opening mechanism is operable by an unlocking device, which is preferably countersunk at the end of the holding device. For example, the unlocking device can be configured as a key or push button, slider or button. The countersink arrangement on the surface of the housing prevents the opening mechanism from starting unexpectedly and allows the opening mechanism to not start unexpectedly no matter where the hair styling device is placed.

  Activation of the unlocking device serves to release the coupling or anchoring device between the cap and the holding device, push the spring-loaded element pretensioned against the cap and move the cap to the release position. In some embodiments of the invention, the retaining device is characterized by a wall portion at its end, which extends inward and restricts the housing for the gas cartridge. This wall part consists of the end of the handle of the hair styling device in the holding device and prevents the gas cartridge from sliding unexpectedly when the cap is opened. For example, if the cap is in the open position and the hair styling device is held in a direction in which the handle end points downward, the wall portion forms a stop position for the gas cartridge so that the gas cartridge Move freely in the housing in the axial direction. In order to take the gas cartridge out of the housing, it is necessary to lift the gas cartridge slightly above the restriction wall portion, which usually requires additional movement on the part of the user. In this way, uncontrollable slip of the gas cartridge is widely avoided.

  In some embodiments of the invention, the wall portion and the cap are configured to form a form-fit snap-on connection. Thus, in the closed position of the cap, the cap part and the wall portion are partially overlapped to form a snap engagement connection. As such, the wall portion and / or cap is characterized by an alignment snap element.

  In some embodiments of the invention, the unlocking device can be actuated against spring tension to release the snap-engagement coupling. The unlocking device can be arranged at the wall portion or cap of the holding device. By activating the unlocking device, depending on the configuration of the snap engagement coupling, the latch or the corresponding relief groove is moved against the spring tension to release the snap engagement coupling. The latch or the corresponding relief groove can be arranged with a wall portion or a cap.

  In some embodiments of the present invention, the spring tension for releasing the snap-engagement coupling is derived from a single spring load element, which is also provided for activating the opening mechanism. For example, a single spring load element has a rectangular spring element inside the cap in such a way that one end contacts the unlocking element located at the end and the other end contacts the cylindrical surface or shell of the inserted gas cartridge. Can be arranged to form.

  In some embodiments of the present invention, the cap is a snap engagement element with at least one latch at an end, wherein the snap engagement element forms a snap engagement connection with a wall portion of the retainer There is a feature. The snap engagement element is configured to be received by the wall portion, and when the snap engagement element leans against the wall portion, the latch is engageable with the corresponding relief groove to provide a conformable snap engagement coupling. Form.

  In some embodiments of the present invention, the retention device and the cap are characterized by alignment outer surfaces that replenish each other and form a cylindrical shape in the closed position. The outer surface of the holding device is tapered toward the end. Thus, in the region of the end of the handle, the cap can surround more than half of the radial periphery of the inserted gas cartridge in the closed position. When the cap is opened, such a configuration allows the user to grip and lift the inserted gas cartridge between the thumb and forefinger below the middle centerline. Thus, when the cap is opened, the side area of the cartridge can be easily accessed, which has the advantage of handling the device during the process of changing the cartridge. Also, in the direction of the end that points to the styling rod, the outer surface of the holding device has been configured to surround the inserted gas cartridge more than the cap. Associating and maximizing the surface of the holding device is particularly advantageous for handling the entire hair styling device during the process of changing the cartridge. For example, the user can safely hold the hair styling device with one hand when the cap is opened.

  The following description of the drawings illustrates further objects, advantages, features, and forms of application of embodiments of the present invention. All features described and / or illustrated are representative of the present invention, alone or in combination.

Detailed description

  FIG. 1 is a perspective view of a hair styling device 1, and the hair styling device 1 has a styling rod 2 and an associated handle 3. The housing of the handle 3 is divided into a holding device 5 and a cap 4 that pivots with the holding device 5. In the open position, the pivoting cap 4 is configured to expose the gas cartridge 6 exposing the housing. The user can insert the gas cartridge 6 into the housing constrained by the holding device 5. Closing the cap 4 pushes the cap 4 into the operating position. At the end, i.e. the side opposite to the styling rod 2, the holding device 5 has a wall portion 8, which extends into the interior, the interior being a housing for the gas cartridge 6 towards the handle end. Limiting the area and consequently preventing the gas cartridge 6 from sliding out of the housing axially in the longitudinal direction while the cap is open.

  The cap 4 has a snap engagement element 7 at its end, which is configured to form a conformable connection with the wall portion 8 of the holding device 5. The snap engaging element 7 is characterized by at least one, preferably two latches 11, 12, which are configured to engage corresponding relief grooves in the wall portion 8. By activating the activation element or button 9, the snap engagement element 7 and the two latches 11, 12 are moved axially towards the styling rod 2 and between the snap engagement element 7 and the wall portion 8. The snap engagement connection is released and the cap 4 is opened.

  In the illustrated embodiment, the cap 4 and the holding device 5 have an outer surface, the outer surfaces replenishing each other to form a cylindrical shape, where the outer surface of the holding device 5 is the handle end. A taper is formed toward the top. As a result, the cap 4 has a wider radial periphery at the end of the handle 3 than the holding device 5, so that below the middle centerline, the gas cartridge 6 is lifted above the wall portion 8, The user can grip the gas cartridge between the thumb and index finger and easily lift the gas cartridge out of the housing.

  The radial periphery of the outer surface of the holding device 5 remains the same in the direction of the styling rod 2. However, it is preferably configured wider than the cap 4. This helps to maximize the radial periphery or shell of the retaining device 5 so that the user can safely handle the handle 3, ie the entire hair styling device 1, with one hand, without having to slip while changing the cartridge. Ensure that you can hold.

  Furthermore, the hair styling device 1 is characterized by two switches 17, 18 in the handle, which can be configured as, for example, key switches, rocker switches, slide switches, and the movable element of the styling rod 2. Have the purpose of operating or adjusting the temperature.

  The gas cartridge 6 is movable in the axial direction in the longitudinal direction of the hair styling device 1 between the operating position and the removal position. In particular, the gas cartridge is pushed to the removal position during the process of opening the cap and pushed to the operating position during the closing process of the cap 4. In the operating position, the left end of the cartridge 6 is pushed onto the needle valve or pin 10 as shown in the perspective view of FIG. Therefore, during the process of closing the cap 4, the gas cartridge 6 is pushed onto the pin 10, resulting in the gas required to operate the hair styling device without further interaction or activation by the user. Gas is extracted from the cartridge 6.

  For example, the gas cartridge 6 is pushed to the pin 10 through the lowering of the cap 4 by a contact component (such as a square surface) disposed inside the cap 4. When the cap 4 is attached to the inserted gas cartridge 6 when closing the handle, the square face arranged inside the cap 4 caps axially longitudinally towards the styling rod 2 and vertically from the outside The force acting on 4 is changed to a displacement force acting basically horizontally. As a result, as shown in FIG. 2, it is not necessary to manually insert or push the gas cartridge 6 into the pin 10 as in some prior art. This has an advantageous effect in terms of ease of handling and user friendliness of the hair styling device 1.

  Within the link area (ie the area of the pivot axis 19), the cap 4 is characterized by a latch or clamp 20, which, when opening the cap 4, causes the gas cartridge 6 to be in the removal position towards the handle end. Useful for the purpose of being pushed. Therefore, when opening the cap 4, the gas cartridge 6 is pulled away from the pin 10. As a result, when the cap 4 is opened, the gas cartridge is basically loosely placed in the housing of the holding device 5 and can be removed by simply lifting the gas cartridge above the wall 8 of the handle 3. It is.

  FIG. 2 shows a perspective view of the hair styling device 1 corresponding to FIG. 1 with the gas cartridge 6 removed. In the view shown in FIG. 2, the needle valve or pin 10 configured to extract gas from the gas cartridge 6 is clearly seen.

  FIG. 3 shows a further perspective view of the handle 3 with the cap 4 open and the gas cartridge 6 removed. This figure clearly shows the activation element 9, which is pierced at the end of the cap 4 and provided with a snap engagement mechanism for opening the cap 4. FIG. 3 also shows a snap engagement element with two latches 11, 12 protruding from the end of the cap 4.

  When the cap 4 is in the closed position, the projection 16 is arranged on the wall portion 8 extending into the interior area of the housing for the gas cartridge 6 but for the two latches 11, 12 of the snap engagement element 7. A relief groove is formed. By depressing the button-shaped actuating element 9, the snap engagement element 7 is moved in the direction of the styling rod 2 and releases the snap engagement connection between the wall part 8 of the holding device 5 and the cap 4. To do.

  The button 9 is pushed down against the spring tension, which ensures that the cap 4 cannot exclusively be opened unintentionally. The countersunk arrangement of the button 9 also has the advantage that, for example, the cap 4 is not opened when the hair styling device 1 is pushed down on the end of the handle 3. Therefore, it is possible to efficiently prevent the cap from being unintentionally opened.

  FIG. 4 shows a perspective view of the inside of the cap 4, the cap 4 having an internal feature at its loose end (ie a snap engaging element at the opposite end of the styling rod 2, two corners 13. , 14 and rectangular spring element 15). During the process of closing the cap 4, both corner surfaces 13, 14 are attached to the inserted gas cartridge 6. By further depressing the cap 4 in the closed position, an axial displacement force is applied to the gas cartridge in the longitudinal direction relative to the styling rod, ensuring that the gas cartridge 6 is pushed by the pin or needle valve 10.

  In the embodiment shown here, the spring element 15 configured as a single unit has a bi-folding function. On the other hand, the spring element 15 arranged on the upper side inside the cap opens the cap 4 with respect to the spring when the snap engagement element is released from the wall portion 8. In the closed position of the cap 4, the spring element 15 is attached to the gas cartridge 6 and is tensioned during the process of closing the cap 4. When the snap engagement mechanism is released, the spring element 15 releases the tension, and the cap 4 is moved from the closed position to the released position, forming a gap between the cap 4 and the holding device 5. In the release position, the cap 4 usually has an opening angle towards the centerline of the hair styling device 1. The gap formed between the cap 4 and the holding device 5 ensures that the cap 4 is safely and easily gripped and opens the cap 4 completely.

  On the other hand, due to the parts attached to the snap engagement element 7, the spring element 15 exerts spring tension and prevents the activation element 9 from being pushed down, so that the two latches 11, 12 of the snap engagement element 7 are always Guarantees that it sticks in place.

  Other embodiments are possible in which the release mechanisms for the snap engagement element and the cap 4 are each activated by a spring element. For example, in such an embodiment, two separate springs can be placed on the inner side of the cap 4 (eg, the snap engagement element 7 and everywhere on the cap 4).

  FIG. 5 shows an inner perspective view of the holding device 5 with the cap 4 opened and the gas cartridge 6 extracted. The wall portion 8 extending inward is clearly visible. On the other hand, this wall portion prevents the gas cartridge 6 from sliding out of the shell formed by the holding device 5. On the other hand, the wall portion forms a relief groove for the snap engagement element 7 of the cap 4 so as to be fixed in place.

  Furthermore, it has been pointed out that, for example, the activation element 9 can also be arranged appropriately on the holding device 5. Furthermore, the snap engagement element 7 can also be arranged on the holding device 5 and the wall part 8 engaging the snap engagement element 7 can be arranged on the cap 4. In other embodiments, the snap engagement mechanism can also be released by a displacement element or a rotation element.

  FIG. 6 shows a radial cross section through the hair styling device 1 with the cap 4 closed and the gas cartridge 6 inserted. Both activation elements 17, 18 for operating the hair styling device 1 are clearly visible because they protrude from the cylindrical shell of the hair styling device 1. Further, cross sections AA, BB, EE, and FF are drawn, and these cross sections are shown in FIGS.

  FIG. 7 shows a cross-section through section EE through the end of the handle 3 with the cap 4 closed. At the lower left edge it can be seen how the latch 12 engages each relief groove formed by the wall portion 8. The button 9 is also shown to interact directly with the snap engagement element 7, which is also shown to form a unit with a latch 12. Therefore, by depressing the button 9, the snap engagement mechanism is released, and the cap 4 is released from the spring 4 due to the spring tension with which the spring 15 is attached to the shell of the gas cartridge 6. In the same way, the vertically arranged spring element 15 keeps the latch 12 in the closed position.

  FIG. 8 shows a cross section along section FF corresponding to FIG. In this cross section, the square face 14 of the cap 4 is clearly visible. When the cap 4 is pushed down, the cap 4 comes to be attached to the left end of the gas cartridge 6 and displaces the gas cartridge 6 to the right (ie, in the direction of the styling rod). Therefore, the vertical force applied to the cap 4 is changed by the square surface 14 to a force applied horizontally to the right on the gas cartridge.

  FIG. 9 shows the cross section along the cross line A-A with the cap 4 opened, as displayed in FIG. The pivot shaft 19 of the cap 4 and the clamp element 20 connected to the cap 4 displace the gas cartridge 6 to the removal position (ie, displace toward the wall portion 8 of the holding device 5).

  When the cap 4 is opened, the clamping element 20 forms a protrusion but comes to stick to the front surface of the left side of the gas cartridge 6. Due to the arrangement and geometry with respect to the pivot axis 19 during the process of opening the cap 4, the clamping element 20 allows the gas cartridge 6 to be pulled away from the needle valve 10.

  FIG. 10 shows a cross section through the handle 3 with the cap 4 closed, corresponding to FIG. Compared with the crossing part of FIG. 9, here, the gas cartridge 6 is displaced toward the left side, so that the needle valve 10 is inserted into the valve 24 of the gas cartridge 6. Since the cap 4 is closed, the clamping element 20 does not need to be attached to the left end of the gas cartridge 6. When the opening mechanism is activated in that the clamping element 20 is not attached to the gas cartridge 6, the cap 4 activated through the tensioned spring element 15 automatically moves from the closed position to the released position. .

  Therefore, after the button is activated, the cap 4 can automatically open a little spring. In order to fully open the cap 4 with the rightward movement of the gas cartridge 6, the user must perform each operation.

  FIG. 11 shows the longitudinal crossing through the handle 3 along the crossing line BB with the cap 4 open, as displayed in FIG. Here, since the gas cartridge 6 is attached to the right side portion of the wall portion 8 of the holding device 5, it is in the removal position. Compared with FIG. 10, it can be seen that the needle valve 10 of FIG. 11 is not inserted into the gas cartridge 6.

  FIG. 12 shows a perspective view of the snap engagement means configured to snap the cap 4 to the open position. The perspective view of FIG. 12 shows the pivoting bearing of the cap 4, which is characterized by a clamp 20 pivoted on the pivot 19 at its end. A cylindrical spacer 21 is disposed around the turning shaft 19. The front side of the cylindrical spacer has at least one protrusion 22, which has two typical recesses of different sizes. In the region of the contact portion with respect to the cylindrical spacer, the clamping element 20 is characterized by a protrusion 23 corresponding to the protrusion 22. Through the rotation of the cap 4 and the accompanying pivoting of the clamping element 20, both the projections 22, 23 are displaced from each other. Due to the inherent flexibility of the plastic material of the clamping element 20 and the spacer 21 or the cap 4, they yield when facing each other. When the cap 4 is in the open position, the protrusion 23 is in the recess 25. The geometry of both protrusions 22, 23 prevents the cap 4 from simply snapping closed by weight. Thus, the snap engagement means represented here prevents the cap 4 from being snap-closed during the process of replacing the gas cartridge 6 automatically and potentially unintentionally.
