  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. (C) A lock receiver provided symmetrically on the lower surface of the tilt table as viewed from the front, and protruding to the lower surface of the pedestal portion through the through hole of the pedestal portion when the tilt table overlaps the pedestal portion. (D) It is attached to the lower surface of the pedestal so that it can slide back and forth, and is urged forward by a spring, engages and restrains the left and right lock receivers in the forward position, and locks in the reverse position. Lock body that releases restraint.

  According to this configuration, the tilt base is locked without being tilted to the left or right normally because the lock receiver provided symmetrically on the lower surface of the tilt base is restrained by the lock body to lock the tilt base. It is locked firmly in the use posture. Since the lock can be released simply by moving the lock body backward, the lock can be easily released by one-hand operation.

  (2) In the vehicle equipment stand having the above-described configuration, the lock receiver may be configured such that when the tilt base is returned to the horizontal position from the forward tilted position and stacked on the pedestal portion, the lock receiver attaches the lock body to the spring. It is characterized by descending while eliminating it against the power, and then being restrained by the lock body.

  According to this configuration, when the tilt base is returned to the horizontal position from the forward tilted posture, the lock is automatically applied, and the trouble of operating the lock body can be saved.

  (3) Further, according to the present invention, in the in-vehicle device stand having the above-described configuration, when the lock body is moved backward between the lock receiver and the lock body to release the lock receiver, a pushing force is applied to the lock receiver. The pushing-up part to be made is formed.

  According to this configuration, the unlocking and tilting of the tilt base are continuously performed by the backward movement of the locking body, so that the in-vehicle device can be tilted forward at once.

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

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1A and 1B are front views, FIG. 2 is a plan view, FIG. 3 is a side view, FIG. 4 is a side view with the tilt base tilted forward, and FIG. A bottom view, FIG. 6 are bottom views in different states, and FIGS. 7 to 9 are partially enlarged sectional views in different states.

  The on-vehicle device stand 1 includes a stand base 2 attached to 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 punching and bending a steel plate with a press machine, 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. 4). ). The tilt table 3 is similarly formed by punching and bending a steel plate with a press machine, and is connected to the tip of the pedestal portion 10 by a pair of left and right horizontal fulcrum shafts 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 table 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 table 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 table 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.

  A fixture 16 is attached to the groove 15. The fixture 16 includes a synthetic resin plug body 17 disposed on the back side of the backrest portion 11, a metal nut plate 18 disposed on the front side of the backrest portion 11, and a nut from the back side of the plug body 17. A screw 19 is screwed into the plate 18. When the screw 19 is tightened, the plug body 17 and the nut plate 18 sandwich the backrest portion 11, and the fixture 16 is fixed to the backrest portion 11 by a frictional force. The fixture 16 can be fixed by shifting its position freely within the range of the length of the groove 15.

  As seen in FIG. 2, the plug body 17 has a T-shaped horizontal cross section. If a socket body (not shown) for receiving the plug body 17 is fixed to the front surface of the dashboard, the stand base 2 can be attached to the dashboard by inserting the plug body 17 into the socket body. Further, the stand base 2 can be easily detached from the dashboard by removing the plug body 17 from the socket body.

  The tilt base 3 to which the in-vehicle device 4 is fixed is normally 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. As described above, 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. 4, the tilt table 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. 3, if the tilt base 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. Details of the lock mechanism will be described below.

  Main components of the lock mechanism are lock receivers 20L and 20R fixed to the lower surface of the tilt base 3, and a lock body 30 disposed on the lower surface of the pedestal portion 10.

  As shown in FIGS. 5 and 6, the lock body 30 has a pair of leg portions 32 </ b> L and 32 </ b> R in a form extending symmetrically from the push button portion 31 disposed on the center line of the pedestal portion 10. It is integrally molded and has a Y-shape as a whole. A plate-like front guide 33 is fixed to the lower surface of the front end portion of the pedestal portion 10, and the push button portion 31 passes through the through hole 34 of the front guide 33 and protrudes to the front side. A block-shaped rear guide 35 is fixed to the lower surface on the rear end side of the base portion 10. The rear guide 35 has guide grooves 36 extending in the front-rear direction on both the left and right sides, and the tips of the legs 32L and 32R are received in the guide grooves 36. In this way, the lock body 30 is supported on the lower surface of the pedestal portion 10 so as to be slidable in the front-rear direction, with the front portion supported by the front guide 33 and the rear portion supported by the rear guide 35. The lock receivers 20L and 20R, the lock body 30, the front guide 33, and the rear guide 35 are all made of synthetic resin.

  A compression coil spring 37 that biases the lock body 30 forward is disposed between the leg portions 32L, 32R and the inner wall of the rear end of the guide groove 36. The front end of the compression coil spring 37 is inserted into a blind hole formed in the leg portions 32L and 32R, and the lock body 30 is moved forward until the shoulder portion between the push button portion 31 and the leg portions 32L and 32R hits the front guide 33. Energize.

  Lock protrusions 38 are formed on the outward side surfaces of the leg portions 32L and 32R so as to protrude perpendicular to the sliding direction of the lock body 30. As shown in FIGS. 7 to 9, the lock protrusion 38 has a wedge-shaped cross-sectional shape with a narrow front, and the lower surface is a downward slope that goes down as it goes rearward.

  The lock receivers 20L and 20R are fixed to the lower surface of the tilt table 3 symmetrically as viewed from the front. Through holes 21 are formed in the pedestal portion 10 according to the positions of the lock receivers 20L and 20R. When the tilt base 3 overlaps the pedestal portion 10, the lock receivers 20L and 20R pass through the through holes 21 and the pedestal portion 10 is formed. Protruding to the bottom of the. The lock receivers 20L and 20R protruding from the lower surface of the pedestal 10 have a shape that sandwiches the lock body 30 from both sides. In addition, the cushion material 40 which receives the tilt base 3 is being fixed to the upper surface of the base part 10 (refer FIG. 7).

  Grooves 22 for receiving the lock protrusions 38 are formed on the side surfaces of the lock receivers 20L and 20R facing the legs 32L and 32R of the lock body 30. The groove 22 is open on the side facing the leg portions 32L and 32R and the side facing the lower side. A hook portion 23 is formed on the front end side of the groove 22 to engage the lock protrusion 38, and the ceiling portion on the rear end side is formed. A downward slope 24 is formed which descends as going backward. The inclined surface 24 is combined with the lock protrusion 38 to constitute the push-up portion 25.

  The operation of the locking mechanism is as follows. When the tilt base 3 is returned to the horizontal position from the forward tilted position shown in FIG. 4 and stacked on the pedestal 10, as shown in FIG. 7, the sloped portions that continue to the hook portions 23 of the lock receivers 20 </ b> L and 20 </ b> R The locking projection 38 is pushed backward. As a result, the lock body 30 moves backward against the urging force of the compression coil spring 37. The lock receivers 20L and 20R are lowered while removing the lock body 30, and finally settle in a state where the tilt base 3 overlaps the pedestal portion 10 with the thickness of the cushion material 40 being separated as shown in FIG. Then, the lock body 30 moves forward by the urging force of the compression coil spring 37 and engages the lock protrusion 38 with the hook portion 23 to restrain the lock receivers 20L and 20R. Since the lower surface of the lock projection 38 is a slope that is lowered downward, the lock projection 38 exerts a downward force on the hook portion 38. As a result, the tilt base 3 is attracted to the cushion material 40, and the back surface of the in-vehicle device 4 is pressed against the cushion material 14. The back surface of the in-vehicle device 4 is softly received by the cushion material 14, and even if the vehicle vibrates thereafter, noise generated by the collision between the in-vehicle device 4 and the stand 1 is prevented. Since the left and right lock receivers 20L and 20R are respectively restrained by the lock protrusions 38, the tilt base 3 is securely locked in the normal use posture without tilting or rattling to the left or right.

  When releasing the lock, the push button portion 31 is pushed and the lock body 30 is slid rearward as shown in FIG. Then, the lock projection 38 is separated from the hook portion 23, and the restraints of the lock receivers 20L and 20R are released. When the lock body 30 is pushed in as it is, the corner at the upper rear end of the lock projection 38 hits the inclined surface 24, and a pushing force is applied to the lock receivers 20L and 20R. As a result, the tilt base 3 is forcibly tilted forward, and the center of gravity of the in-vehicle device 4 moves to the left side from the fulcrum shaft 12, resulting in the state of FIG. In this way, the unlocking and tilting of the tilt base 3 are continuously performed by the backward movement of the lock body 30, and the in-vehicle device 4 can be tilted forward in one behavior.

  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.
