DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a separator bar which is bridged in a vehicle width direction and separates an operator's cab from a cargo room.

[0002]

2. Description of the Related Art In a van-type commercial vehicle, when luggage that is higher than the height of the front seats is loaded in a luggage compartment, the cargo collapses forward due to sudden braking, vibration or impact during traveling, and the luggage is lost. There is a problem that the vehicle falls into the cab. In order to solve such a problem, it is known that a separator bar that separates a driver's cab from a luggage compartment is mounted so as to span the vehicle width direction (Japanese Utility Model Publication No. 4-3871).

[0003] However, in the case of the separator bar, a spring is built in a telescopic inner / outer pipe.
By compressing the springs, the springs and the pipes built into the separator bar vibrate due to body vibration or the like, so that the springs and the pipes are likely to generate abnormal noise. In addition, since the inner and outer pipes are configured to be inserted into each other, the strength of the joints of the pipes is low. Further, there is a disadvantage that the structure of the separator bar itself is complicated and processing cost is increased.

[0004]

SUMMARY OF THE INVENTION
As disclosed in Japanese Patent Publication No. 038, a device using one rod-shaped separator bar has also been proposed. In this case, since the separator bar is composed of one bar, the rigidity is high and the structure is simple. However, since a through hole for inserting one end of the separator bar must be formed in the pillar inner, the strength of the vehicle body is reduced, and in a state where the separator bar is removed, the through hole of the pillar inner is exposed. The shine is bad. Further, a bracket is welded and fixed to the other end of the separator bar, and this bracket is screwed to the pillar inner, so that the separator bar cannot be easily attached or detached.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a separator bar mounting structure which has a high rigidity of the separator bar, has a simple structure, and does not reduce the strength of the vehicle body. Another object of the present invention is to provide a mounting structure for a separator bar which is easy to mount and remove.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a mounting structure of a separator bar which is spanned in a vehicle width direction and separates a driver's cab from a luggage compartment. And a pair of support members for supporting both end portions of the separator bar. The support members have a receiving groove opened upward, and a plurality of vertically continuous receiving grooves are formed on one inner surface of the receiving groove. A serration engaging with the teeth is formed on an outer peripheral surface of an end portion of the separator bar fitted in the receiving groove. Is formed, and by engaging the serrations of the separator bar with the teeth of the support tool and rotating the separator bar to a position over the locking projection, the end of the separator bar can be fitted to the bottom of the receiving groove of the support tool. Also It is.

When the end of the separator bar is inserted into the receiving groove of the support from above, the serration of the separator bar engages with the teeth formed on the inner surface of the receiving groove, so that the separator bar is inserted while rotating. During the insertion,
When the serration of the separator bar comes into contact with the locking projection formed on the inner surface on the opposite side of the receiving groove, and is forcibly rotated to get over this projection, the end of the separator bar becomes the bottom of the receiving groove of the support tool. Fits.

When the end of the separator bar is removed from the receiving groove of the support, the separator bar is rotated in the direction opposite to the insertion direction so that the serration of the separator bar goes over the locking projection while engaging with the teeth. Therefore, the separator bar can be easily removed from the receiving groove.

When the separator bar is fitted in the bottom of the receiving groove of the support, even if an external force is applied to the separator bar upward, the serrations of the separator bar may simultaneously climb over the teeth and the locking projections. Since the separator bar cannot be rotated, the separator bar does not come off unless the separator bar is rotated.

It is preferable that the locking projection provided on the inner surface of the receiving groove of the support is provided at an intermediate position between the teeth. Further, the teeth need not be provided up to the bottom of the receiving groove, and when the separator bar is fitted to the bottom of the receiving groove, the serrations do not need to mesh with the teeth. Therefore, the separator bar may be rotatable in the receiving groove. However, in order to more stably hold the separator bar when the separator bar is mounted, it is preferable that the separator bar does not rotate. For this purpose, the serration is set to the tooth portion while the separator bar is fitted to the bottom of the receiving groove. It is better to engage. In order to more stably hold the separator bar in the receiving groove, it is desirable to provide the locking projection at a position where it comes into contact with the serration while the separator bar is fitted to the bottom of the receiving groove.

[0011]

FIG. 1 shows the interior structure of a van type vehicle using the present invention. In the figure, reference numeral 1 denotes an operator's cab, 2 denotes a luggage compartment, and a front seat 3 is arranged in the operator's cab 1. Reference numeral 4 denotes a center pillar, and a separator bar 5 separating the cab 1 and the cargo room 2 is provided on the inner wall of the center pillar 4.
Is spanned in the vehicle width direction.

The separator bar 5 is, as shown in FIG.
A bar body 6 made of a straight metal pipe;
And resin caps 7 fitted to both left and right ends of the lens. Two fitting holes 6a are formed near both ends of the bar main body 6, and are formed on the outer surface of the inner end 7a when the inner end 7a of the cap 7 is fitted to one end of the bar main body 6. The cap 7 is fixed to the bar main body 6 so as not to be rotatable by being fitted into the fitting hole 6a. Serrations 7d are formed on the outer peripheral surface of the outer end 7c of the cap 7. The cap 7
The outer diameter of the outer end 7c is slightly smaller than the outer diameter of the bar body 6.

A pair of supports 10 for supporting the separator bar 5 are fixed to the inner wall of the center pillar 4. The support 10 includes a metal bracket 11 and a resin cover 12 as shown in FIG.
The bracket 11 is formed by pressing a single metal plate, has two bolt insertion holes 11a formed on the front side, a U-shaped opening 11b formed on the rear side, and has an outer periphery formed with a bolt. The continuous peripheral wall 11c is bent vertically. On the other hand, the cover 12 is an outer peripheral wall 11c of the bracket 11.
The front side has an insertion hole 12a corresponding to the bolt insertion hole 11a, and the rear side has a U-shaped receiving groove 12b corresponding to the opening 11b. Are formed. The insertion holes 11a, 12
The support member 10 is fixed by inserting the bolt 13 into the center pillar 4 and tightening it together with the center pillar 4.

As shown in FIGS. 4 to 6, the receiving groove 12b has a large diameter portion 12c into which the bar body 6 is fitted,
Has a two-stage structure with the small diameter portion 12d to be fitted. On the side end surface of the small-diameter portion 12d, an elastic piece 12e that is in pressure contact with the end surface of the cap 7 is formed. A plurality of (three in the figure) teeth portions 12f meshing with the serrations 7d of the cap 7 are continuously formed on the front inner surface of the small diameter portion 12d in the vertical direction, and an inner surface facing the intermediate position of these tooth portions 12f. Is formed with a mountain-shaped locking projection 12g. The tooth portion 12f and the locking projection 12g are continuous in the depth direction (horizontal direction) of the small diameter portion 12d. When the serration 7d of the cap 7 is fitted to the bottom of the receiving groove 12b, the lowermost tooth portion 12f is formed at a position where it engages with the serration 7d, and the locking projection 12g is formed by the serration 7d.
(See FIG. 6).

As shown in FIG. 6, a gap D is provided between the side wall of the receiving groove 12b of the cover 12 and the opening 11b of the bracket 11, and the gap D is formed so as to fill the gap D. A plurality of reinforcing ribs 12h are provided on the outer peripheral surface so as to be in contact with the inner surface of the opening 11b of the bracket 11. The rib 12h prevents the receiving groove 12b from laterally oscillating. The rib 12h is offset downward with respect to the locking projection 12g, and the opening 11b of the bracket 11 supports the outside of the large-diameter portion 12c of the receiving groove 12b via the rib 12h (FIG. 5
Therefore, when the separator bar 5 is fitted, the small diameter portion 12d can be elastically deformed in the width direction.

The separator bar 5 having the above structure is connected to the support 10
The method of attaching to the device will be described. When the end of the separator bar 5 is inserted from above the receiving groove 12b of the support 10, the serration 7d engages with the teeth 12f on the inner surface of the receiving groove 12b during the insertion, and the separator bar 5 rotates clockwise in FIG. I do. Eventually, since the outer peripheral surface of the serration 7d hits the locking projection 12g, the separator bar 5 is forcibly rotated in the clockwise direction.
d climbs over the locking projection 12g, and the separator bar 5 is fitted and held at the lowest point (bottom) of the receiving groove 12b (shown by a solid line in FIG. 6).

When the serration 7d gets over the locking projection 12g, the receiving groove 12b slightly expands in the width direction, but a gap D is provided between the side wall of the receiving groove 12b and the opening 11b of the bracket 11. Therefore, the receiving groove 12f can be easily elastically deformed. Separator bar 5 is receiving groove 12b
In the state where the serrations 7d are engaged with the teeth 12f and the upward movement is restricted by the locking projections 12g, the rotation and vertical movement of the separator bar 5 are prevented. 5 is receiving groove 12b
Locked stably at the bottom of the At this time, since the end face of the cap 7 is in pressure contact with the elastic piece 12e, rattling in the axial direction (vehicle width direction) of the separator bar 5 is also restricted.

The separator bar 5 is inserted into the receiving groove 1 of the support 10.
Even if an external force acts upward on the separator bar 5 in the state of being fitted to 2b, the vertical movement of the serrations 7d is regulated by the teeth 12f and the locking projections 12g.
The serrations 5 are stably held at the bottom of the receiving groove 12b and do not escape upward.

On the other hand, when removing the separator bar 5 from the support 10, the separator bar 5 is rotated in the opposite direction to that at the time of fitting, that is, in the counterclockwise direction in FIG. As a result, the serrations 7d rotate while engaging with the teeth 12f, and get over the locking projections 12g, thereby releasing the lock,
The separator bar 5 can be removed above the groove 12b. As described above, since the separator bar 5 can be easily attached to and detached from the support 10, it is possible to move the separator bar 5 from the front seat 3 to the cargo room 2.
Also when moving to, the separator bar 5 can be easily attached and detached from the front seat 3 side.

The present invention is not limited to the above embodiment. In the above-described embodiment, the separator bar has a straight rod shape. However, for example, a bent portion or a curved portion may be provided in the middle portion, or another member that connects between the separator bar and the ceiling wall is connected to the middle portion. May be. As a support,
The present invention is not limited to the one constituted by the metal bracket and the resin cover as in the embodiment, but may be one integrally formed of metal, resin, rubber material or the like.

[0021]

As is apparent from the above description, according to the present invention, since one bar is used as the separator bar, the rigidity is high and the structure is simplified. In addition, since the support member may be fixed to the inner wall of the vehicle body for mounting the separator bar, it is not necessary to form a through hole or the like in the vehicle body, and the strength of the vehicle body does not decrease. In the present invention, since the teeth and the locking projections are formed on the inner surface of the receiving groove of the support tool, and the serrations that mesh with the teeth are formed on the separator bar.
By inserting the separator bar into the receiving groove while rotating the separator bar, the separator bar can be easily fitted into the receiving groove of the support, and it can be easily removed by rotating the separator bar in the opposite direction to the insertion Can also. In addition, in a state where the end of the separator bar is fitted to the bottom of the receiving groove of the support, the separator bar cannot be removed from the receiving groove unless the separator bar is rotated, so that even when an external force acts upward on the separator bar, The separator bar does not easily fall out of the receiving groove.
