Technical Field

The present invention relates to a work light device for a vehicle and/or a vehicle comprising the work light device.

The invention can be applied to heavy vehicles such as trucks, buses and construction equipment. Although the invention will be described with reference to a heavy truck, the invention is not limited to this particular vehicle, but may also be used in other vehicles, such as light trucks, articulated haulers, excavators, wheel loaders and backhoe loaders.

Background

Commercial vehicles (e.g., trucks) may be equipped with one or more worklights for illuminating certain areas of the truck in the event of poor ambient light conditions, for example, to perform a pre-trip inspection of the truck. These worklights are typically provided at predetermined locations on the vehicle, such as at the rear of the truck cab, at the roof of the vehicle, along the chassis frame of the vehicle, and the like. The worklight may also be mounted on a trailer of the vehicle.

Known worklight apparatuses include one or more worklights disposed on a vehicle, which are attached at fixed locations. It is also known to have portable worklights, wherein one such design can be found in patent application US 2019/0092225 a 1.

While it is known to have portable worklights for vehicles, there is still an effort to provide an improved worklight apparatus that is easy for a user to operate, which provides beneficial lighting performance and is cost effective.

Disclosure of Invention

In view of the above, it is an object of the present invention to provide an improved work light device for a vehicle, which at least in some aspects alleviates at least one of the disadvantages of the prior art and/or provides a good alternative.

According to a first aspect, the object is achieved by a worklight device for a vehicle according to claim 1. According to a second aspect, the object is achieved by a vehicle according to claim 15.

According to a first aspect of the present invention, this object is achieved by a work light device for a vehicle, comprising:

a portable worklight comprising a light emitting means,

-at least a first preset mount and one or more second mounts for portable worklights, the at least first preset mount and the one or more second mounts being adapted to be mounted to the vehicle at different locations of the vehicle,

wherein the portable worklight comprises a body and a connecting member for selectively and releasably mounting the portable worklight to the at least first preset mount and the one or more second mounts,

wherein the connecting member is a rod-like member having a longitudinal extension along its central axis, wherein the rod-like member protrudes from the main body, and at least one of the one or more second brackets comprises a concave receiving portion for receiving the rod-like member.

By providing a worklight apparatus as disclosed herein, a cost-effective worklight apparatus construction for a vehicle is achieved, and further a portable worklight is provided that is easy for a user to operate. More specifically, by having one first preset bracket and one or more second brackets provided to the vehicle at different locations of the vehicle, the user can easily bring the portable work light to different locations when needed. Furthermore, by configuring the connecting member as a rod-like member protruding from the main body, a cost-effective connecting configuration is provided that is also easy for a user to operate. In fact, the rod-shaped member will be easily recognized by the user as a connecting member, thereby providing an intuitive connecting procedure, i.e. the user will easily understand how to connect the portable worklight, even if the portable worklight is being used for the first time.

A rod-like member as used herein may be defined as an elongate member which extends in longitudinal extension along its central axis and which projects from the body, and which is preferably substantially cylindrical. The cross-section of the generally cylindrical member may be circular, oval, square, rectangular, or any other suitable shape that is capable of being received in the female receiving portion. According to an exemplary embodiment, the rod-shaped member may deviate from the cylindrical shape by having a slightly conical shape, whereby the diameter of the rod-shaped member decreases slightly in a direction away from the body.

The first preset cradle is preferably a cradle to which the portable worklight should be mounted when the user is not using the portable worklight. However, it should be noted that the portable worklight can also be used to illuminate a portion of the vehicle when the portable worklight is mounted to the first preset mount. Preferably, the first preset bracket is mounted to a cab of the vehicle (e.g. the cab of a truck).

Optionally, the female receiving portion may comprise an aperture into which the rod-like member is adapted to be inserted in the direction of the central axis, whereby the female receiving portion and the rod-like member are adapted such that the rod-like member is releasably mountable to at least one of the one or more second brackets when the rod-like member is received in the female receiving portion. Still alternatively, the female receiving portion and the rod-like member may be adapted such that the rod-like member is rotatable about the central axis when releasably mounted inside the female receiving portion. Thus, the user can easily adjust the direction of the light emitting device by rotating the portable worklight. Thus, and still optionally, the body may be rigidly attached to the rod-like member, thereby providing a more cost-effective construction that does not require any joints or the like between the rod-like member and the body. As another example, the portable worklight may include a joint between the rod-like member and the main body, thereby increasing the degree of freedom in adjusting the orientation of the light-emitting device. The joint may be configured such that the body may pivot about a central axis of the rod-like member and/or about an axis substantially perpendicular to the central axis. Still optionally, at least one of the one or more second brackets including a concave receiving portion and an aperture adapted for insertion of a rod-like member further includes a cover (e.g., a spring-biased swivel tab) that covers the aperture when the portable worklight is not mounted to the at least one of the one or more second brackets. Thus, when the portable worklight is mounted to, for example, the first preset bracket, the interior of the concave receiving portion can be protected and sealed from the exterior.

Optionally, the at least one of the one or more second brackets comprising a female receiving portion and a rod-like member comprises a locking means for locking the rod-like member in the female receiving portion when the rod-like member is mounted in the female receiving portion, the locking means locking the rod-like member such that the rod-like member is locked in the direction of the central axis. Thus, the portable worklight is not accidentally released from the at least one of the one or more second brackets when the user is using the portable worklight and, for example, rotating the portable worklight to illuminate a different portion of the vehicle or the vehicle surroundings. Still alternatively, the locking device may be a spring-based locking device.

Optionally, the first preset bracket may comprise a receiving portion (e.g. a recess) for receiving the rod-like member such that the rod-like member can be releasably mounted to the receiving portion. Still optionally, when the receiving portion of the first preset holder is a recess, the recess is adapted to enable the rod member to be inserted into the recess in a direction substantially perpendicular to a central axis of the rod member. That is, it has been appreciated that it may be preferred that the first preset stent has a different configuration than the one or more second stents. That is, the first preset bracket may be configured to provide a safe and reliable connection to the portable worklight while the vehicle is traveling. Thus, the configuration of the one or more second brackets, which are more preferably configured to provide a beneficial connection when using a portable worklight, may not be suitable for safely and reliably storing the portable worklight while the vehicle is moving.

Alternatively, the recess of the first preset holder may extend from an inlet portion, where the rod-like member can be inserted, to an end portion, which defines an end stop for the rod-like member, whereby the recess extends in a first extension portion from the inlet portion to an intermediate portion, followed by a second extension portion from the intermediate portion to the end portion, wherein the first and second extension portions of the recess are angled with respect to each other. Therefore, when the rod-shaped member is inserted into the recess, the portable worklight can be securely mounted to the first preset bracket by changing the direction. In fact, by said construction, the risk of accidental release of the portable worklight can be mitigated. Still alternatively, the recess may be substantially L-shaped.

Optionally, the first preset bracket may comprise a spring biased member (e.g. a spring biased plunger member) for locking the work light to the recess when the rod member is located in the recess, preferably when the rod member is located at an end of the recess. Thus, the portable worklight can be releasably mounted in a reliable manner. Still optionally, the spring-biased member may be adapted to be movable in a first direction and provide a spring-biasing force onto the portable worklight such that the rod-like member may be moved from the middle portion to the end portion and locked in a locked position at the end portion by the provided spring-biasing force. Still optionally, the spring biased member may also be movable in an opposite second direction such that the rod member may be released from the locked position at the end. The foregoing construction has been shown to provide a secure and reliable connection that is also easy to operate by the user.

Alternatively, the first preset bracket may be adapted such that the rod-like member is substantially unable to rotate about the central axis when mounted to the first preset bracket. Therefore, the portable worklight can be safely mounted to the vehicle when the vehicle is moving, thereby reducing the risk of damage to the portable worklight.

Optionally, the portable worklight may comprise an energy storage system (preferably a battery), and wherein preferably at least the first pre-determined cradle comprises charging means for charging the energy storage system when the portable worklight is mounted to the first pre-determined cradle. Therefore, when the portable work light is mounted to the first preset bracket, the portable work light can be charged. Alternatively or additionally, the at least one second holder may also comprise a charging device for charging the portable worklight. Furthermore, by having an energy storage system, the portable worklight can be easily used by a user without the need for, for example, cables, which can negatively impact the portability of the portable worklight.

Alternatively, the light emitting means may be any kind of light source, such as any kind of light source generating light from an electric current, such as preferably an LED (light emitting diode) lamp, but the light emitting means may also be a halogen lamp, an incandescent lamp, etc. Especially, the LED lamp is preferable because the LED lamp generates strong light with low power consumption.

Still optionally, the portable worklight can include a handle for a user to hold the portable worklight. The handle is preferably mounted (e.g., pivotally mounted) to the body of the portable worklight. By using the handle, the user can easily move the portable worklight to different locations around the vehicle.

According to a second aspect of the invention, the object is achieved by a vehicle comprising a worklight device according to any embodiment of the first aspect of the invention.

The advantages and effects provided by the second aspect of the invention are largely similar to those provided by the lamp unit housing according to the embodiment of the first aspect of the invention. It should also be noted that all embodiments of the second aspect of the invention are applicable to and can be combined with all embodiments of the first aspect of the invention, and vice versa.

Detailed Description

Fig. 1 shows a vehicle 1 in the form of a trailer according to an exemplary embodiment of a second aspect of the present invention. The trailer 1 comprises a worklight device 100 according to an exemplary embodiment of the first aspect of the invention. The worklight device 100 comprises a first pre-set bracket 20 attached to the rear wall of the cab 2 of the truck 1 and a second bracket 30 attached at the rear of the truck 1. The invention is not limited to this type of vehicle but may be applied to any other type of vehicle, such as any other type of heavy duty truck, bus, construction equipment vehicle, etc.

Referring to, for example, fig. 2a and 2b, a more detailed perspective view of the worklight apparatus 100 is shown. The worklight apparatus 100 comprises a portable worklight 10 comprising a light emitting device. The worklight apparatus also includes at least a first preset cradle 20 and one or more second cradles 30 for the portable worklight 10 that are adapted to be mounted to the vehicle 1 at different locations thereon, as shown in fig. 1. The portable worklight 10 includes a body 11 and a connecting member 12 for selectively and releasably mounting the portable worklight 10 to the at least first preset mount 20 and the one or more second mounts 30. The body 11 includes a light emitting device. Said connecting member 12 is a rod-like member having a longitudinal extension along its central axis C and wherein said rod-like member 12 protrudes from the main body 11 and at least one of the one or more second brackets 30 comprises a concave receiving portion 31 for receiving said rod-like member 12.

Furthermore, said female receiving portion 31 comprises an aperture 32 into which said rod-like member 12 is adapted to be inserted in the direction of the central axis C, as indicated by the arrow in fig. 2 a. The female receiving portion 31 and the rod-like member 12 are adapted such that the rod-like member 12 can be releasably mounted to at least one of the one or more second brackets 30 when the rod-like member 12 is received in the female receiving portion 31. The aperture 32 may also be closed by a cover (not shown) when the portable worklight 10 is not installed therein. The cover may for example be a rotatable cover, such as a spring biased rotating cover or a flip cover. Such a cover/flip can protect and seal the interior of the second housing when the portable worklight 10 is not mounted to the second housing 30.

Furthermore, the female receiving portion 31 and the rod-like member 12 are adapted such that the rod-like member 12 can rotate about the central axis C when releasably mounted inside the female receiving portion 31. Thus, the user can easily adjust the orientation of the light emitting device by rotating the portable worklight 10 about the central axis C. As described above, the main body 11 may be rigidly attached to the rod member 12, or the portable worklight 10 may include a joint (not shown) between the rod member 12 and the main body 10 that is configured such that the main body 11 may pivot about the central axis C of the rod member 12. The second bracket 30 may also comprise connecting means 34, such as screws, rivets, bolts, or the like, for connecting the second bracket to the vehicle 1. The connecting device 34 is, for example, configured such that the second bracket 30 can be mounted on a substantially horizontal surface of the vehicle 1.

At least one of the one or more second brackets 30 (e.g. as shown in fig. 2 a) and the rod-like member 12 comprise locking means 121, 33 for locking the rod-like member 12 in the female receiving portion 31 when said rod-like member is mounted in said female receiving portion 31. The locking means 121, 33 lock the rod-shaped member 12 such that it is locked in the direction of the central axis C. Thus, the portable work light 10 is not accidentally released from the at least one of the one or more second brackets 30 while the user is using the portable work light 10 and rotating the portable work light, for example, about the central axis C to illuminate a different portion of the vehicle 1 or to illuminate the surroundings of the vehicle 1. The portion 33 of the locking means 121, 33 provided on the second bracket 30 is spring-based. More precisely, the portion 33 comprises a first and a second spring-biased member 33 (e.g. buttons as shown), whereby pushing the first and second buttons releases the rod-like member 12 from said second holder 30. The rod-shaped member 12 comprises a recess 121 in which clamping means (not shown) are placed for locking the portable worklight 10 to the second bracket 30 in a snap-fit connection. Said clamping means are spring biased and provide a clamping force at said recess 121 to said rod-like member, thereby preventing the portable worklight from being released from the second bracket in the direction of the C-axis. In the embodiment shown, the rod-like member 12 is a substantially cylindrical member having a substantially circular cross-section, for example as seen in a sectional plane perpendicular to the central axis C. Furthermore, the diameter of the cross section of the rod-shaped member 12 decreases slightly in a direction away from said body 11, so that the substantially cylindrical rod-shaped member 12 instead acquires a slightly conical profile. Therefore, the rod-like member 12 can be inserted into the concave receiving portion 31 and the aperture 32 thereof more easily.

Furthermore, as shown in fig. 2b, the first preset bracket 20 comprises a receiving portion 21 in the shape of a recess for receiving the rod-like member 12 such that the rod-like member 12 can be releasably mounted thereto. The recess 21 is adapted such that the rod member 12 can be inserted into the recess in a direction T substantially perpendicular to the central axis C of the rod member 12. Furthermore, as shown in fig. 2b, the rod member 12 may include a waist portion 122 near the main body 11, the waist portion having a reduced diameter compared to the diameter of the portion of the rod member 12 disposed below the waist portion 122, as viewed when the portable worklight 10 is in an upright position. The waist 122 is adapted to be arranged in the recess 21. This configuration improves the locking of the portable worklight 10, particularly in the direction of the central axis C.

The recess 21 extends from an inlet portion 211, where the rod member 12 can be inserted, to an end portion 212 defining an end stop for the rod member 12. Furthermore, the recess 21 extends in a first extension from the inlet portion 211 to an intermediate portion 213, followed by a second extension from the intermediate portion 213 to the end portion 212, wherein the first and second extensions of the recess 21 are angled with respect to each other. In the embodiment shown, the first and second extensions are angled at approximately 90 degrees, thereby forming a substantially L-shaped recess 21. Furthermore, said recess 21 is provided in a substantially horizontal plane, as is observed when the first preset bracket is mounted on the vehicle 1, for example on the rear wall of the cab 2.

As shown in fig. 2b, the first preset bracket 20 comprises a spring biased plunger member 22, the spring biased plunger member 22 being adapted to lock the portable worklight 10 thereto when the rod member 12 is located at the end 212 of the recess 21. The spring biased plunger 22 is adapted to be movable in a first direction and to provide a spring biasing force onto the portable worklight 10 such that the rod-like member 12 is movable from the middle portion 213 to the end portion 212 and is locked in a locked position at the end portion 212 by the provided spring biasing force. Further, the spring-biased plunger member 22 is also movable in a second, opposite direction, such that the rod-like member 12 may be released from the locked position at the end 212.

The first preset cradle 20 is further adapted such that when the rod-like member 12 is mounted to the first preset cradle and disposed at the end 212, the rod-like member is substantially incapable of rotation about the central axis C. Therefore, the portable work light 10 can be safely mounted to the vehicle 1 when the vehicle 1 moves, thereby reducing the risk of damage to the portable work light 10. The first preset cradle 20 may include a first side wall 214 and a second side wall 215 that prevent the portable work light 10 from rotating about the central axis C when the portable work light is disposed in the recess 21. The first preset support 20 may also comprise a rear wall 216 configured to be mounted, for example, on a vertical cab wall of the vehicle 1. Here, the spring biased plunger 22 is mounted to the first sidewall 214. The rear wall 216 and the first and second side walls 214, 215 define a receiving space for the body 11.

The rod-like member 12 and the body 11 may be mounted to each other, for example by means of screws/rivets/bolts or the like, or by any other type of connection means. The body 11 is also rotatable at the connection between the body 11 and the rod-like member 12, for example about an axis substantially perpendicular to the central axis C. However, the rod-like member 12 and the body 11 may alternatively be integrated into one single piece.

The light emitting means of the portable worklight is an LED lamp as shown in fig. 2a and 2 b. Further, according to an example embodiment of the present invention, the portable worklight 10 may be configured such that the light emitting device may be automatically turned on when the portable worklight 10 is released from the first preset cradle 20 and/or automatically turned off when the portable worklight 10 is brought back and locked to the first preset cradle 20. Thus, a user may not need to manually turn the light on/off while using the portable worklight 10.

The portable worklight 10 also includes a handle 13 for a user to hold the portable worklight 10. The handle 13 is preferably mounted (e.g., pivotally mounted) to the body of the portable worklight. The handle 13 may be rotatable, for example, about an axis substantially perpendicular to the central axis C.

Fig. 3 shows the worklight device 100 when it is mounted on the rear wall of the cab 2 of the vehicle 1 via the rear wall 216. As can also be observed, the portable worklight 10 can be charged via an electrical connection 14 that charges a battery (not shown) of the portable worklight 10.

Fig. 4a to 4c show the sequence when the portable worklight is released from the first preset cradle 20. The portable worklight 10 is first positioned at the end 212 whereby the spring-biased plunger 22 has moved in the second direction such that the rod-like member 12 is released from the locked position at the end 12. This is preferably done by the user pulling on the spring biased plunger 22. Subsequently, the rod-shaped member 12 may be moved to the intermediate portion 213, as shown in fig. 4b, and may finally be released from the recess 21 by removing the rod-shaped member from the recess 21, as shown in fig. 4 c. The user may hold the handle 13 and/or the rod member 12 when releasing the portable worklight 10.

Fig. 5 shows the working lamp device 100 when the rod-like member 12 is disposed in the concave receiving portion 31.

It is to be understood that the invention is not limited to the embodiments described above and shown in the drawings; rather, one of ordinary skill in the art appreciates that various changes and modifications can be made within the scope of the appended claims.
