Description

[Detailed Description of the Invention] The present invention relates to a jack storage structure for an automobile.

Generally, automobiles are equipped with jacks for jacking up the vehicle body when changing tires, etc., and the jacks are stored in a storage space formed by a vehicle body panel or the like.

By the way, pantograph type jacks are common as the type of jacks installed in cars.This jack has a base part that touches the ground, a head part that receives the bottom of the car body, etc., and a part that connects the base part and the head part. two arm parts connecting the parts are formed in a pantograph shape, and the head part is configured to move up and down by rotating a threaded rod provided through the center of each of the opposing arm parts. There is.

As a conventional technique for storing such a pantograph jack in a storage space provided in a vehicle, as shown in Japanese Utility Model Application Publication No. 49-54236, a bracket is fixed to a component of the vehicle body such as an inner corner of a trunk room. There was one in which a wheel chock was fitted into the bracket, and the jack was housed inside the chevron of the wheel chock, and the jack was fixedly stored in the bracket via the wheel chock.

However, in such a jack storage structure, gaps are created in various parts due to play and variations in the dimensions of the jack itself, as well as variations in the dimensions of the bracket. After the jack is placed in the bracket, the screw rod of the jack is turned to push the head and base against their respective abutting surfaces, so that the jack is fixed in a tensioned state on the bracket. However, the jack is generally stored in a narrow space such as a trunk room, and it is sometimes difficult to provide enough space to turn the threaded rod after the jack is stored in the storage space as described above.

In addition, in view of the fact that the above operations are extremely difficult, there are some models in which the jack head is fixed to the bracket with a thumbscrew, etc.; Since the base part of the jack is not firmly fixed due to the pressure of the jack, there is also a drawback that abnormal noises are generated during driving due to backlash due to the buckling of the threaded rod part of the jack itself.

The present invention was made in order to solve the above-mentioned conventional problems.The jack storage space is formed by a vehicle body panel at a position lower than the floor, and the jack base part is attached to a bracket arranged in the storage space. a long side having a short side facing the , a contact part that comes into contact with a corner of the jack base, a receiving part that comes into contact with a side surface of the jack's head, and a bead that comes into contact with a corner of the jack's head. By pressing the head of the jack against the bracket with a bolt, the head and base of the jack can be securely fixed to the bracket, eliminating abnormal noises that occur during driving. To provide a jack storage structure for an automobile that can easily and reliably fix the jack even in a narrow storage space.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing a jack storage structure according to an embodiment of the present invention. In the figure, 1 is a trunk room formed at the rear of the automobile, and the trunk room 1 is located at a position lower than the floor 2 at the right or left end. A jack storage space 4 is formed by the vehicle body panel 3. The length of the jack storage space 4 in the longitudinal direction of the vehicle is somewhat longer than the length of the pantograph jack 5 in the folded state, as shown in FIG. 1a. Further, a bracket 6 for fixedly storing the jack 5 is provided approximately in the center of the storage space 4, and even when the folded jack 5 is stored in the bracket 6, the jack 5 can be fixedly stored therein. is arranged so that the head 5a does not protrude above the two surfaces of the floor.

FIG. 2 is an enlarged view of the bracket 6,
The bracket 6 is made of a metal plate having a substantially L-shaped cross section, and has a continuous long side 7, an abutment 8a, a short side 9, and an abutment 8b. The long side portion 7 has a receiving portion 7a for contacting and receiving the side surface of the head 5a of the jack 5, and a nut for screwing the bolt 10 on the back surface of the receiving portion 7a. 11 is installed. Further, on the side opposite to the short side 9 of the nut mounting portion of the receiving portion 7a, that is, on the upper side of the nut 11 mounting portion, two convex beads 7b and 7c are provided at the same height position. The lower halves of the two beads 7b and 7c are both smoothly inclined downward toward the short side 9. The short side portion 9 is formed to face the jack base portion 5b when the jack 5 is housed in the bracket 6. The contact portions 8b and 8a are provided at the front end of the short side portion 9 and at the boundary with the long side portion 9, and the contact portions 8a and 8b extend outward from the end of the short side portion 9. It is formed so as to be inclined and come into contact with both corner portions of the jack base portion 5b.

Next, the function and effect will be explained. First, the folded jack 5 is stored in the bracket 6. At this time, as shown in FIG.
a, 8b, and the corner of the jack head 5a abuts on the two beads 7b, 7c of the bracket 6. In this state, gaps are created in various parts due to backlash of the threaded rod portion of the jack 5 itself and variations in the mounting dimensions between the jack 5 and the bracket 6. In this state, the bolt 10 is passed through the recess provided in the jack head 5a and the nut 1 attached to the receiving part 7a is inserted.
1 and screw the above-mentioned jack 5 into the above-mentioned bracket 6.
Tighten and press against. Then, the jack head 5a, which was in the state shown by the two-dot chain line in FIG. becomes the state of Therefore, the bumps of the jack 5 itself and the gaps created in various parts are eliminated, and the jack 5
is securely fixed.

According to this embodiment as described above, the jack can be easily and reliably fixed even in a narrow space with a simple structure, and no abnormal noise is generated during driving. Furthermore, since the storage space is located at a lower level than the floor, by placing a mat or the like on top of it, it is possible to secure a sufficiently large cargo space in the trunk room.

In the above embodiment, both the front end of the short side of the bracket and the abutting part of the boundary with the long side are inclined outward from the end of the short side. It is also possible to simply provide one of the abutting portions by slanting them outward.

As described above, according to the present invention, the bracket for storing the jack is formed with a contact part that contacts the corner of the jack base and a bead that contacts the side surface of the jack head, and the jack is mounted on the bracket. After storing the jack, the bolt is used to press the jack against the bracket, and the head and base of the jack are firmly fixed to the bracket by the bead and the abutting part, which eliminates abnormal noises that occur while driving. In addition, the above-mentioned jack can be easily and reliably fixed even in a narrow storage space.
