Description

Technical Field

[0001] This invention relates to the field of headlamps, and in particular to a headband for headlamps. Background Technology

[0002] There are many types of headlamp headbands. Recent significant advancements in headlamps have led to the design of particularly complex headbands to support not only the headlamp located at the front of the user's head, but also the large battery located at the rear of the headlamp, which powers it.

[0003] Figure 1 An example of a well-known solution used in a high-power lamp sold by the applicant of this patent application is shown. Figure 1 A headband comprising two parts is shown: a first part 110 at the front (on which the headlamp housing 100 is attached) and a second part at the rear. The second part includes a support 140 for holding the battery 150 and a connector 130a / 130b for connecting the front part 110 and the rear support 140. A locking device 170 allows the connector to be locked in an adjustable manner to ensure that the assembly can be adjusted for various head shapes and even helmets.

[0004] The electrical connection between the battery 150 and the headlamp housing 100 is made by an electrical conductor 160, which is in the form of a twist or spiral to provide various adjustment configurations, allowing the headband to be stretched when it must be attached to a large head or even a safety helmet.

[0005] Already noticed Figure 1 The known solutions have a number of drawbacks.

[0006] First, note the significant discomfort associated with the tension of the spiral conductor 160: the spring force of the conductor 160 is necessary to ensure minimal aesthetic support for the conductor, and it pulls on one side of the headband. This spring force is very clearly perceived as unpleasant by the wearer of the lamp, and requires periodic refocusing when he begins strenuous activities such as running.

[0007] Secondly, as shown in the figure, the spiral conductor 160 is relatively large and bulky, which is not only detrimental to the aesthetics of the entire headband, but also to its compactness. Summary of the Invention

[0008] In summary, the applicant is looking for a support solution that is smaller, more comfortable, and more elegant, while ensuring that the headband can be adjusted for various head types, even on safety helmets.

[0009] This is the problem that this invention aims to solve.

[0010] The purpose of this invention is to propose a new headband structure designed to hold the headlamp, ensure electrical connection between the headlamp housing at the front and the power battery at the rear, while reducing the impact of cable tension perceptible to the user.

[0011] Another object of the present invention is to provide a compact headlamp structure that allows for adjustment for different head sizes and even safety helmets.

[0012] Another object of the present invention is to provide a headlamp headband structure having two parts attached by an adjusting link, the two parts being a front part and a rear part, respectively.

[0013] The present invention achieves these objectives through a novel arrangement of headlights and headbands, including front and rear sections.

[0014] Figure 2 The front portion 205 is shown, which includes a headband element configured to accommodate the lamp body and includes two ends, each end including a through-hole or vertical conduit configured for sliding passage of a tensioning resilient link. One end also includes a first attachment clip that protrudes to form a horizontal sliding connection with the conductive cord 270.

[0015] The rear section includes a support for holding the battery and the locking lever. The support includes two attachment points at its bottom for tightening the resilient link, one on the left and one on the right, and two through holes in its upper section to ensure the resilient link can pass through, although the resilient link can be blocked by the locking lever 260.

[0016] According to the invention, the tensioning elastic link is constructed to pass successively through the left attachment point on the bottom of the rear support member, then proceed toward and exit through the vertical guide tube at the first end, engaging with the upper left through-hole of the rear support member to form an adjustable and lockable ring in the rear via the locking rod. On the right side, the tensioning elastic link exits from the upper right through-hole of the rear support member to engage with the vertical guide tube at the second end, then engages with the right attachment point on the bottom of the rear support member.

[0017] The headband also includes:

[0018] Conductive rope with two radii of curvature to form a "Z" shape;

[0019] A first movable clip is located at the level of a first radius of curvature to ensure that the conductive cord slides together with the upper part of the tension elastic link;

[0020] A second movable clip is located at the level of the second radius of curvature to allow the conductive cord to slide together with the lower part of the tensioning elastic link.

[0021] In one embodiment, one end provides a mutually perpendicular double sliding connection between the conductive cord and the tensioning elastic link.

[0022] In another embodiment, the two ends are preferably formed by molding or sewing onto an elastic headband forming the front.

[0023] Preferably, the end has the shape of a generally square or rectangular ring, with one hollow vertical side serving as a vertical conduit for vertically sliding the tensioned elastic link. Attached Figure Description

[0024] Other features, objects, and advantages of the invention will become apparent upon reading the following description and accompanying drawings, which are given by way of non-limiting example only. In the drawings:

[0032] Figure 8A , Figure 8B , Figure 8C and Figure 8D Details of the locking lever 260 on the support at the rear 240 of the headband are shown. Detailed Implementation

[0033] Figure 2 A left rear perspective view of a preferred embodiment of a fixing strap according to one embodiment of the present invention is shown, and its various constituent elements are also shown. Figure 3 and Figure 4 A left view is shown based on two unfolded positions of the conductive rope.

[0034] like Figure 2 As shown, the headband has a front portion 205 and a rear portion 240 that are interconnected by a tension elastic link 230.

[0035] The front portion 205 is in the form of a headband element, made of fabric, plastic, or any other suitable material, preferably elastic, to which the lamp body 200 is secured. Different securing methods are conceivable to ensure the lamp body 200 remains on the front portion 205, and for the sake of simplicity, they will not be described in detail here. For example, simply providing two holes in the lamp body 200 for the headband element of the front portion 205 to pass through could ensure a sliding connection of the lamp body 200 on the front portion 205. However, it is clear that other embodiments are possible and conceivable.

[0036] The headband element of the front portion 205 includes two ends, a left end and a right end, and two plastic ends 210 and 220 are preferably fixed to these two ends by overmolding or sewing. Each of the two plastic ends has a through hole or vertical guide 211 and 221, respectively, for the sliding passage of the tension elastic link 230. Preferably, the plastic ends 210 and 220 have a generally square or rectangular ring shape, with one hollow vertical side serving as a vertical guide 211 / 221 for the vertical sliding of the tension elastic link 230.

[0037] In addition, such as Figure 2 , Figure 3 and Figure 4 As shown, the plastic end 210 also includes a first attachment clip 215, which is protruding and provides a horizontal sliding connection with the conductive cord 270. Details of the end 210 are shown in... Figures 7A-7C As shown in the figure, and will be described later.

[0038] This particular arrangement allows it to be observed that, at the level of the plastic end 210, mutually perpendicular double sliding connections are thus provided for the conductive cord 270 (horizontal sliding) and the tensioning elastic link 230 (vertical sliding), respectively.

[0039] The rear portion 240 of the headband includes a support member with a substantially symmetrical shape in the midsagittal plane and is configured to match the shape of the back of the user's head. Preferably, the support member is triangular in form and has a bottom with two attachment points (a left attachment point and a right attachment point at the two ends of the tensioning elastic link 230, respectively). Figure 3 The left attachment point 241 of the tensioning resilient link 230 is shown more specifically; the right attachment point is not visible in this figure. The bottom of the rear portion 240 also includes a protrusion that allows the battery body 250, connected to the conductive cord 270, to be attached via the connector 242. On the upper part of the rear portion 240, two through holes are provided on the left and right sides respectively to ensure the passage of the tensioning resilient link 230. These two through holes engage with the vertical locking lever 260 to allow simultaneous locking of both sides of the tensioning resilient link 230. Figures 8A-8D The rear section 240 and its locking lever 260 are shown in more detail.

[0040] It can be seen that the proposed headband has significant tensioning possibilities due to the unique and particularly advantageous specific path of the tensioning elastic link 230, which successively passes through the left attachment point 241 on the bottom of the support of the rear portion 240, then proceeds toward and exits from the left vertical guide tube 211 of the end 210 and engages with the upper left through hole of the rear portion 240 to form an adjustable loop at the rear portion 240, and as... Figures 8A-8D As shown, the ring is lockable via the vertical locking rod 260, and on the right side, it emerges from the upper right through-hole of the support member of the rear 240 and engages with the vertical sliding guide 221 of the end 220, and then engages with the right attachment point at the bottom of the rear 240.

[0041] This process of tightening the elastic link 230 allows it to be held particularly effectively and comfortably over the user's head because it results in the appearance of a double tensioning ring (a lower tensioning ring and an upper tensioning ring, respectively) that can be tightened by a single vertical locking lever 260.

[0042] Furthermore, in order to electrically connect the battery 250 to the lamp body 200, the conductive rope 270, which has a very specific shape, is provided with two radii of curvature (respectively...). Figure 3 As shown in 271 and 272), the two radii of curvature fall within the user's sagittal plane to form a "Z" shape and advantageously cooperate with the process of tightening the elastic link 230.

[0043] For this purpose, two movable clips 280 and 290 are provided, which allow a sliding connection between the conductive cord 270 and the tension elastic link 230. Movable clip 280 is located at the level of a first radius of curvature 271 to ensure sliding together with the upper part of the tension elastic link 230, while movable clip 290 is located at the level of a second radius of curvature 272 to allow sliding together with the lower part of the tension elastic link 230.

[0044] Details of the implementation of the movable clip 290 are in Figures 5A-5C As shown in the middle, Figures 6A-6C Embodiments of movable clips 280 are shown, which allow conductive cords 270 to engage with tension elastic links 230.

[0045] The result is a sophisticated arrangement that elegantly ensures great efficiency in maintaining the headband.

[0046] In summary, the connection of the conductive rope 270 from the lamp body 200 to the battery 250 can be as follows:

[0047] - Connector 201 for electrical connection of lamp body 200;

[0048] -A first sliding connection positioned at the level of a first attachment clip 215 protruding from end 210;

[0049] - A second sliding connection at the level of the second clamp 280 near the first radius of curvature, thereby providing a double sliding connection with the upper part of the tensioned elastic link 230 traveling toward the upper left through hole of the support;

[0050] - A third sliding connection at the level of the third clip 290 near the second radius of curvature, thereby providing a double sliding connection with the lower part of the tensioned resilient link 230 from the attachment point 241 of the support.

[0051] - Connector 242 that allows electrical connection to the battery.

[0052] These sliding links, in conjunction with the sliding possibility of the tension resilient link 230, ultimately allow for a wide range of adjustment possibilities, such as... Figure 3 and Figure 4 As shown, it illustrates two different expansion structures: the minimum expansion structure and the maximum expansion structure.

[0053] Of particular note and advantageously, the first end 210 forms a mutually perpendicular double sliding connection at the level of the conductive cord 270 and the tension resilient link 230. In effect, the attachment clip 215 allows the conductive cord 270 to slide substantially horizontally, while the vertical conduits 211, 221 provide vertical sliding along the tension resilient link 230.

[0054] In a preferred embodiment, the battery can be connected to the support via a micro USB connector.
