  The present invention relates to a vehicle-mounted device stand used for installing a vehicle-mounted device such as a car navigation device on a dashboard of a vehicle.

When an in-vehicle device such as a car navigation device or a television is retrofitted to an automobile, a method is generally employed in which a stand is fixed to the dashboard of the automobile and the in-vehicle device is attached to the stand. An example of such a stand can be seen in US Pat.
JP-A-8-337144 (page 2-3, FIG. 1-3)

  For the convenience of operation of the in-vehicle device, the in-vehicle device stand may be required to be able to tilt (tilt) at a portion where the in-vehicle device is attached. When the tiltable portion is provided, a lock mechanism is required so as not to inadvertently shift to the tilt state due to the acceleration or vibration of the automobile.

  The present invention has been made in view of the above problems, and provides a stand for an in-vehicle device that can support an in-vehicle device in a tiltable manner, can be reliably locked in a normal use posture that is not in a tilted state, and can be easily unlocked. With the goal.

(1) In order to achieve the above object, the vehicle equipment stand of the present invention is characterized by having the following configuration.
(A) A side base L-shaped stand base composed of a horizontal pedestal portion and a vertical backrest portion (b) It is connected to the tip of the pedestal portion by a horizontal fulcrum shaft and includes a fixing means for fixing an in-vehicle device. Tilt base (c) Attached to one side of the tilt base and locked to engage the stand base to prevent the tilt base from tilting forward, and can be detached from the stand base to tilt the tilt base forward (D) A lock lever that can be in both of the released postures (d) It is slidably attached to the pedestal portion in a form parallel to the fulcrum shaft, and is urged toward the lock lever by a spring, so that the lock lever When one end is pushed by the lock lever, the tilt base is restrained by the other end, and when the lock lever is in the release position, the spring is biased by the biasing force of the spring. Lock shaft to slide the door stand in a non-binding position.

  According to this configuration, the tilt lever locks the tilt base on one side of the tilt base, and the lock shaft locks the tilt base on the other side. The And since it is sufficient to release the lock only by setting the lock lever to the release position, the lock can be easily released by one-handed operation.

  (2) Further, the present invention is characterized in that in the on-vehicle equipment stand having the above-described configuration, an elastic engagement portion is provided between the stand base and the lock lever to maintain the lock lever in a locked posture. Yes.

  According to this configuration, it is possible to prevent the lock lever in the lock posture from being inadvertently changed to the release posture due to the vibration of the automobile.

  (3) Further, the present invention is characterized in that, in the on-vehicle device stand having the above-described configuration, a cushion material for receiving the back surface of the on-vehicle device fixed to the tilt base is attached to the front surface of the backrest portion.

  According to this configuration, the in-vehicle device in the normal use posture can be softly received by the cushion material, and noise generated by the collision between the in-vehicle device and the stand can be prevented.

  According to the present invention, the tilt base is locked on both sides by the lock lever and the lock shaft, and the in-vehicle device attached to the tilt base can be firmly held in the normal use posture. Since the lock can be released only by operating the lock lever, the lock can be easily released with one hand operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. All the figures show a stand for in-vehicle equipment, FIG. 1 is a front view, FIG. 2 is a plan view, FIG. 3 is a partially enlarged sectional view, FIG. 4 is a plan view in a different state, FIG. 6 is a side view of the tilt base tilted forward, FIG. 7 is a bottom view, and FIG. 8 is a bottom view of a different state.

  The on-vehicle device stand 1 includes a stand base 2 fixed on a dashboard of an automobile (not shown) and its accessory parts, a tilt base 3 connected to the stand base 2 so as to be tiltable, and its accessory parts.

  The stand base 2 is formed by stamping and bending a steel plate with a press, and is a side-shaped L-shaped component in which a horizontal pedestal portion 10 and a vertical backrest portion 11 are connected (see FIG. 6). It is. The tilt table 3 is similarly formed by punching and bending a steel plate with a press, and is connected to the tip of the pedestal portion 10 by a horizontal fulcrum shaft 12. The tilt table 3 can be rotated (tilted) within a predetermined angle range within a vertical plane with the fulcrum shaft 12 as a rotation center.

  The in-vehicle device 4 is fixed to the tilt base 3 as shown in FIGS. The in-vehicle device 4 is a virtual line and only a silhouette is illustrated, but this assumes a car navigation device. The in-vehicle device 4 has a monitor unit 4a on the front side and a disc player unit 4b on the back side. The monitor unit 4a includes a display screen using a liquid crystal display panel. The disc player unit 4b takes in a disc-shaped information medium 5 such as a DVD or a CD by a slot-in method, and a slot for this purpose is formed on the upper surface. A fixing screw 13 is attached to the tilt base 3 like a camera tripod head, and the fixing screw 13 constitutes a fixing means for fixing the in-vehicle device 4 to the tilt base 3.

  A cushion material 14 for receiving the back surface of the in-vehicle device 4 fixed to the tilt base 3 is attached to the front surface of the backrest portion 11 of the stand base 2. The cushion material 14 is a rectangular parallelepiped member made of a synthetic resin foam, and is bonded one by one to both sides of the center line of the backrest portion 11 so that its long axis is vertical. A groove 15 extending vertically along the center line of the backrest portion 11 is formed between the left and right cushion members 14.

  The tilt base 3 to which the in-vehicle device 4 is fixed is usually used by being horizontally stacked on the base portion 10 as shown in FIG. At this time, the display screen of the in-vehicle device 4 is vertical, and the back surface of the in-vehicle device 4 is exactly pressed against the cushion material 14. Thus, when the in-vehicle device 4 stands upright, it is difficult to take in and out the disc-shaped information medium 5. Therefore, when the disc-shaped information medium 5 is taken in and out, the tilt base 3 is tilted forward as shown in FIG. In FIG. 6, the tilt base 3 is tilted forward to the limit, and the center of gravity of the in-vehicle device 4 is on the left side of the fulcrum shaft 12. Therefore, even if the hand is released from the in-vehicle device 4, the in-vehicle device 4 remains at the angle shown in FIG.

  When the in-vehicle device 4 is used in the normal use posture as shown in FIG. 5, if the tilt table 3 is not restrained, the in-vehicle device 4 is in the state shown in FIG. There can be a situation of conversion. In order to avoid such a situation, a lock mechanism for maintaining the normal use posture of the tilt table 3 is provided. The lock lever 20 and the lock shaft 30 constitute the lock mechanism.

  An ear piece 21 is integrally formed on the tilt table 3 so as to protrude rightward when viewed from the front. The lock lever 20 is rotatably connected to the front end portion of the ear piece 21 by a fulcrum shaft 22 perpendicular to the in-vehicle device support plane of the tilt base 3. An ear piece 23 is also integrally formed on the pedestal portion 10 so as to protrude to the right side when viewed from the front. When the tilt base 3 overlaps the pedestal 10, the ear pieces 21 and 23 also overlap vertically.

  The lock lever 20 is a part made of synthetic resin, and a finger-hanging portion 24 is formed at the rotation end, and a clamping portion 25 having a U-shaped cross section as shown in FIG. 3 is formed in the middle. Yes. When the tilt lever 3 is overlaid on the pedestal 10 and the lock lever 20 is at the angle shown in FIG. 2, the overlapping ear pieces 21 and 23 are sandwiched from above and below by the clamping part 25 as shown in FIG. It is. Thereby, the tilt base 3 cannot lift its rear part. That is, the tilt table 3 is locked in the normal use posture, and the posture of the lock lever 20 at this time is the lock posture.

  When the lock lever 20 is at the angle shown in FIG. 4, the holding portion 25 is separated from the ear pieces 21 and 23 as indicated by a virtual line in FIG. 3. As a result, the tilt base 3 can lift its rear part. The posture of the lock lever 20 at this time is the release posture.

  An annular protrusion 26 is provided on the lower surface of the ear piece 23, and a notch 27 for receiving the protrusion 26 is formed on the lock lever 20 (see FIG. 7). On one side wall of the cutout portion 27, an elastic engagement portion 28 using the elasticity of the synthetic resin that is the material of the lock lever 20 is formed. The elastic engagement portion 28 is formed by providing a groove parallel to the side wall of the notch 27 in the lock lever 20 and inflating a part of the groove outward. When the lock lever 20 is in the locked posture, the elastic engagement portion 28 is elastically engaged with the protrusion 26. Thereby, it is possible to prevent the lock lever 20 in the lock posture from being inadvertently changed to the release posture due to the vibration of the automobile.

  The lock lever 20 is locked on the right side as viewed from the front of the tilt table 3. If you want to completely prevent the tilt table 3 from shaking, it is necessary to lock the left side as viewed from the front. For this purpose, a lock shaft 30 was prepared.

  As seen in FIGS. 7 and 8, bent pieces 31 and 32 are formed on the left and right side edges of the pedestal portion 10 so as to hang downward. Bending pieces 33 and 34 are also formed on the left and right side edges of the tilt table 3 so as to overlap the outside of the bending pieces 31 and 32. Base blocks 35L and 35R made of synthetic resin are arranged between the bent pieces 31 and 32, and are bonded and fixed to the base 10. Except for the narrow bent piece 34, the bent piece 32, the pedestal block 35R, the pedestal block 35L, the bent piece 31, and the bent piece 33 (depending on the arrangement order from right to left) are continuously penetrated. A horizontal through hole is formed, through which the lock shaft 30 is passed. The lock shaft 30 is slidable in the axial direction, one end of which protrudes from the bent piece 32 and faces the lock lever 20, and the other end passes through the bent piece 33 and slightly protrudes therefrom. An E ring 36 is fitted between the base blocks 35L and 35R on the lock lever 20, and a compression coil spring 37 is inserted between the E ring 36 and the base block 35L. Due to the elastic force of the compression coil spring 37, the lock shaft 30 is always biased toward the side where the lock lever 20 exists.

  When the tilt base 3 is overlaid on the pedestal 10 and the lock lever 20 is brought into the locked position, the lock shaft 30 is pushed at the right end by the lock lever 20 and resists the elastic force of the compression coil spring 37 as shown in FIG. And slide to the left. Then, the left end of the lock shaft 30 penetrates the bent piece 33 of the tilt table 3, and the tilt table 3 is restrained. Coupled with the fact that the lock lever 20 locks the right side of the tilt base 3, the tilt base 3 is locked on both the left and right sides, and the in-vehicle device 4 fixed to the tilt base 3 does not rattle and is in a normal use posture. Holds firmly. At this time, the back surface of the in-vehicle device 4 is softly received by the cushion material 14, and even if the automobile vibrates thereafter, noise generated by the collision between the in-vehicle device 4 and the stand 1 is prevented.

  When the disk-shaped information medium 5 is inserted or removed, the lock lever 20 is operated with one hand to take the release posture of FIG. Then, the lock shaft 30 slides to the right side by the elastic force of the compression coil spring 37 and comes out of the bent piece 33. As a result, the tilt base 3 is unlocked on both the right side and the left side, and can be tilted forward. After the tilt base 3 is tilted forward, the center of gravity of the in-vehicle device 4 comes to the front of the fulcrum shaft 12, so that the tilt base 3 maintains the forward tilting posture even when the hand is released from the in-vehicle device 4.

  When the disk-shaped information medium 5 is taken in and out, the in-vehicle device 4 is returned to the upright posture, the lock lever 20 is brought into the lock posture, and the lock of the tilt base 3 by the lock lever 20 and the lock shaft 30 is restored.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  The present invention can be widely used for an on-vehicle device stand.
