Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition structure provided with a partition that can be pulled out and wound up.
The present invention relates to a partition structure provided with a lock mechanism for fixing and supporting a divider in a pulled-out state.

[0002]

2. Description of the Related Art As a winding type partitioning structure provided with a drawer that can be pulled out and wound up, generally, a cylindrical body is rotatably supported with respect to a case, and a base end is provided on the outer periphery of the cylindrical body. Wrap the divider with the fixed. Further, the cylindrical body is urged to rotate by a spring member or the like in a direction in which the partition is wound.

In the partition structure thus configured, a case is fixed to one of the spaces to be partitioned, and a hook or the like for locking the leading end of the partition is fixed to the other. Then, the leading end of the partition pulled out of the case against the rotational urging force of the spring member is fixed to a hook, so that the partition is stretched so as to partition the space. When storing the partition, the leading end of the partition is removed from the hook, so that the partition is wound around a cylindrical body that is rotated by the rotational urging force of the spring member and stored in the case. In a state where the partition is pulled out and fixed to the hook, the partition is pulled by the rotational biasing force of the spring member so as to be always wound around the cylindrical body.

[0004]

However, in the above-described conventional partition structure, the partition cannot be fixed at an arbitrary drawn position unless it is hooked on a hook.
Therefore, there are the following problems.

For example, when a conventional partitioning structure is used to partition a luggage compartment of an automobile or the like to hold the luggage so as to prevent the luggage from moving, when the luggage moves due to vibration or the like, a pulling force acts on the partitioning curtain. However, the partition is further pulled out from the initial state where the luggage is held, and as a result, the luggage cannot be reliably held.

In view of the above problem, there has been an attempt to use the following partition locking mechanism in response to a request to fix the partition at the drawn-out position. This partition curtain locking mechanism is a mechanism generally employed in a roll curtain or the like. When the partition curtain is pulled out and released, the winding rotation preventing function is activated, and the rotation of the cylindrical body is prevented. Is the drawer position,
It remains pulled out. Then, when winding up the partition, by slightly pulling out the drawn-out partition, the take-up rotation preventing function is released, and the partition is wound up around the cylindrical body and easily stored in the case.

However, in the above-mentioned partition locking mechanism, the drawn-out partition can be kept as it is, but cannot be fixed in the pulled-out state. That is,
When a force in a direction in which the partition is pulled out is applied to the partition in the pulled-out state by some external force, the partition can be pulled out, and thus the baggage cannot be reliably held as described above.

Accordingly, an object of the present invention is to provide a partition structure capable of fixing a drawn-out partition curtain in order to solve the above-mentioned problems.

A gear 29, which is a component of a lock mechanism to be described later, is fixed to an outer periphery of the fixed member 21 fitted to the outside of the fixed member 7.

That is, the cylindrical body 15 has a fixed member 21 at one end shown in FIG. 3 rotatably supported on the outer periphery of the pipe shaft 27, and a fixed member 21 at the other end shown in FIG. It is supported rotatably. Further, the cylindrical body 15 is movable in the axial direction with respect to the support shaft 11 and the pipe shaft 27.

A thrust bearing 31 is inserted through the outer periphery of the pipe shaft 27 so as to contact the side plate 7 at one end.

The coil spring 23 pulls the support shaft 11 rightward in FIG. 1 and pulls the cylindrical body 15 leftward in FIG. 1 around the winding unit 1 assembled as shown in FIG. It is creating a biasing force. That is, the support shaft 1
1 receives an urging force inserted into the support hole 13 of the side plate 7,
The cylindrical body 15 receives an urging force in which the fixing member 21 on one end side (left side) comes into contact with the thrust bearing 31. Thereby, the cylindrical body 15 can rotate with respect to the fixed support shaft 11 via the coil spring 23, and the rotation is smoothly performed by the thrust bearing 31.

Further, the winding unit 1 assembled as shown in FIG.
In the state where the partition 25 is entirely wound around the core pipe 17 of the cylindrical body 15, the coil spring 23 is configured such that a rotational urging force for further winding the partition 25 is applied to the cylindrical body 15. At the time of assembling, a twist has been added.

The claw portion 53 is moved to the right side along the longitudinal direction of the opening hole 49 as shown in FIG. 6 so that the claw portion 53 is locked to the gear 29 to prevent the rotation of the cylindrical body 15 (lock position). In addition, the claw portion 53 has the opening hole 4.
By moving to the left side in FIG. 6 along the longitudinal direction of No. 9, the engagement with the gear 29 is released and the rotation of the cylindrical body 15 is enabled (release position).

A compression spring 55 as a first urging member is disposed between the slider 45 and the housing 43. The compression spring 55 urges the slider 45 to the left in FIG.

Further, the head 53a of the claw portion 53 is arranged as shown in FIG.
As shown in (c), it is formed wider than the base 53b. The width of the head 53 a is the width of the widened portion 49 of the opening hole 49.
The width is substantially the same as the width a. That is, the widening portion 49
6 is slid to the left of the opening 49 from the widened portion 49a, so that the base 53b is inserted into the opening 49. That is, the claw portion 53 is regulated so as to slide only in the longitudinal direction of the opening hole 49.

When the claw portion 53 is located at the lock position shown in FIG.
The tooth portion 29 a of the ninth comes into contact with the claw 53, and the inclined portion 29 b of the gear 29 comes into contact with the tip of the claw 53. As a result, the clockwise and counterclockwise rotation of the gear 29 is prevented.

The lock member 47 is connected to the front side of the slider 45 via a shaft 63 and can swing vertically. In this state, the lock member 47 is

As shown in the figure, the small claw 5 protruding in the same direction as the claw portion 53
7 are protruded. The small claw 57 is adapted to be locked in a locking hole 51 provided in the housing 43. Also, as shown in FIG. 6, on the front side of the lock member 47,
A lever 61 projecting out of the housing 43 is attached.

A leaf spring 59 as a second urging member is provided on the bottom surface of the slider 45 between the bottom surface of the case 3 and the second urging member for constantly pushing the lock member 47 upward. The leaf spring 59 always urges the lock member 47 in the direction in which the small claw 57 is locked in the locking hole 51.

When the small claw 57 of the lock member 47 is locked in the locking hole 51 as shown in FIG. Lock position.

When the lever 61 is pushed downward in FIG. 6, the lock between the small claw 57 and the lock hole 51 of the lock member 47 is released. Thereby, the slider 45 is moved leftward in FIG. 6 by the urging force of the compression spring 55, and the slider 45 is moved so that the claw portion 53 is at the release position.

When the lock mechanism 41 is at the release position, the lock member 47 is moved together with the slider 45 by the compression spring 5.
6 is moved to the left in FIG. 6 by the urging force of 5, and the lock between the small claw 57 and the lock hole 51 remains released. In this state, the lock member 47 is kept being pushed upward by the urging force of the leaf spring 59.

When the lever 61 is pushed rightward in FIG. 6, the lock member 47 is pushed upward by the urging force of the leaf spring 59, and the small claw 57 is locked in the locking hole 51.
Thereby, the movement of the slider 45 is restricted by setting the claw portion 53 to the locked position in FIG. 6 again.

Therefore, in the lock mechanism 41, the slider 45 can be moved by operating the lever 61. When the claw portion 53 of the slider 45 is at the lock position, the claw portion 53 is locked to the gear 29 to prevent the rotation of the tubular body 15, and the rewinding and pulling-out of the partition 25 is disabled and locked. Further, when the claw 53 of the slider 45 is at the release position by operating the lever 61, the engagement of the claw 53 with the gear 29 is released, and the cylinder 15 is rotatable. Withdrawal can be done freely.

Next, an example of the use of the partition structure thus configured will be described. FIG. 10 is an explanatory view of a tension pattern of a partition when the partition structure is provided at an upper position of a backrest of a vehicle, and FIG. 11 is a description of a tension pattern of a divider when the partition structure is provided at a lower position of a backrest of the vehicle. FIG.

As shown in FIG. 10, the case 3 includes a rear seat 7 for a vehicle such as a wagon having a luggage compartment 71 at the rear.
3 is attached to the upper position of the backrest 73a. At the front end of the partition 25, a crosspiece 75 shown in FIG.
A clasp 77 is fixed to the crosspiece 75. That is, when the wind-type partition 1 is attached to the upper position of the backrest 73a, a hook (not shown) capable of hanging the clasp 77 is
The partition 25 can be stretched so as to partition the space of the luggage compartment 71 by being attached to the positions A to E, etc. In addition, when the hook is attached to the position F, the backrest 73a is of a retractable type, and is applicable when the case 3 is directly attached to the upper part of the backrest 73a.

As shown in FIG. 11, when the case 3 is attached to the lower part of the backrest 73a, the partition 25 is stretched over hooks attached at positions G, H, etc. The movement of the luggage loaded on 71 can be fixed.

Then, as shown in FIGS. 10 and 11, when the partition 25 is pulled out of the case 3 and the crosspiece 75 is hooked on the hook, the lock mechanism 41 is set to the lock position. That is, the rotation of the cylinder 15 is restricted, and the
5 will not be rewound any further and will not be pulled out. Accordingly, when the load loaded in the luggage compartment 71 is covered with the partition 25, the load is moved by vibration or the like, and the fixing of the partition 25 is released even if a tensile load is applied to the partition 25. There is no luggage and partition 25
Will be fixed by

When the partition 25 is loosely hooked on the hook at the position B in FIG. 10, the partition 25 can be formed into a hammock as shown by a chain line. As a result, it becomes possible to load the luggage on the divider 25 in a loose state.

Therefore, according to the above-mentioned roll-up partition 1, when the luggage is covered with the partition 25, even if a tensile load is applied to the partition 25, the state where the partition 25 is stretched by the lock mechanism 41. Is not released and the partition 25
Can securely fix the luggage. In addition, the luggage can be placed on the divider 25 in a loose state.

In the embodiment described above, the partition 25 may be constituted by a net. If the partition 25 is a net, for example, when the luggage loaded in the luggage compartment 71 of the vehicle is covered, the luggage is appropriately held by the stitches of the net. Further, since the net has elasticity in the stitches, it is possible to absorb vibrations and the like applied to the fixed luggage.

When the partition 25 is constituted by a net, FIG.
As shown in (1), it is preferable to provide a flexible elongated strip 33 along the winding direction of the partition 25. It is sufficient that at least two strips 33 are provided at the side edges of the net.
By providing the band 33 in the winding direction in this manner, the rigidity of the partition 25 made of a net is reinforced, the shape of the partition 25 is stabilized, At the time of rewinding, the partition 25 is less likely to be deformed.
In addition, the band 33 increases the fixing force of the net in the winding direction, and the luggage can be more securely fixed.

Further, in the above-described embodiment, the case where the single partition 25 is provided as the partition structure has been described as an example. However, the above-described partition structure may be provided in two stages, 25 may be wound twice, and the parallel partition 25 may be arranged double in the horizontal direction. With such a double configuration, it is possible to place a load on the lower partition 25 and fix the load on the upper partition 25.

Further, in the above-described embodiment, the case where the partition structure is provided in the cargo room 71 of the vehicle has been described as an example. However, this partition structure may be used in a place where the partition 25 is to be used in a fixed state. The same effect as described above can be obtained regardless of the location, such as the use of a curtain in a window or the like, the partitioning of a room in a house, or the like.

[0054]

As described above, in the partition structure according to the present invention, if the rotation of the cylindrical body is regulated by the lock mechanism after the partition is pulled out, the partition can be further rewound and pulled out. No more. When this partition structure is used, for example, to cover a load loaded in a luggage compartment of a vehicle, the load is moved due to vibration or the like, and the fixing of the partition is released even if a tensile load is applied to the partition. And the luggage can be securely fixed by the divider.

Further, according to the present partition structure, the partition can be fixed in a loosened state. Thereby, for example, the luggage can be placed on the divider in a loose state.

The lock mechanism moves the slider urged by the first urging member to engage the gear fixed to the cylinder with the same central axis with the claw portion of the slider. Is maintained or released, ensuring reliable rotation of the cylinder,
That is, the partition can be fixed.

Further, a lock member which regulates the sliding of the slider, maintains the engagement state of the gear and the claw portion, and releases the locking by releasing the lock by the swing of the slider, is used as the locking member of the slider. The operability of the lock member is improved by the second urging member that urges in the swing direction for restricting sliding.

Further, by using a net as the partition, for example, when the luggage loaded in the luggage compartment of the vehicle is covered, the luggage is appropriately held by the stitches of the net. Also,
Since the net has elasticity in the stitches, it is possible to absorb vibrations and the like applied to the fixed luggage.

In the case where the partition is made of a net, the rigidity of the partition made of the net is reinforced by providing a flexible and long band in the winding direction,
The shape is stable, and the partition is less likely to be deformed at the time of drawing or rewinding. Further, the band increases the fixing force of the net in the winding direction, and the luggage can be fixed more reliably.

Further, the cylindrical body is pressed by a thrust bearing provided in its own central axis direction by the biasing force of the coil spring and supported rotatably, so that the axial force which increases or decreases when the partition is pulled out can be reduced. Without being affected
The cylinder can always be kept in a smooth rotating state.
