Description

  The present invention relates to a belt attachment.

  2. Description of the Related Art Conventionally, there has been known a belt attaching tool attached to a rail fixed to a side wall of a truck luggage compartment (for example, see Patent Document 1). For example, as shown in FIG. 23, a pair of the belt attachments are arranged at intervals in a predetermined direction, and are detachably engaged with engagement holes provided on the rail 110 at intervals in the longitudinal direction. And a pair of engaging portions 201 are fixed, and when the pair of engaging portions 201 are engaged with the engaging holes, a main body portion 202 is disposed substantially parallel to the rail 110, and a main body portion 202 is provided. And a belt mounting portion 210 fixed to one end in the predetermined direction.

  The belt attachment portion 210 is formed by bending a metal plate. The belt mounting portion 210 includes a first portion 211 extending obliquely away from the rail 110 in the predetermined direction from the main body portion 202, a second portion 212 extending from the tip of the first portion 211 toward the rail 110, A third portion 213 extending from the tip of the second portion 212 to the main body 202 side.

JP 2001-106255 A

  For example, when the bag is to be prevented from moving backward by the belt, the engaging members 300 provided at both ends of the belt are respectively attached to both side walls of the luggage compartment. That is, the engaging members 300 at both ends of the belt are attached to the belt attaching members attached to the left and right rails 110, respectively.

  At this time, the rail 110 extends in the front-rear direction of the truck, and the belt extends obliquely rearward from the belt mounting portion 210 toward the center in the width direction of the luggage compartment. There is a possibility that tension of several t or tens of t will be applied to the belt. Therefore, in order to prevent deformation near the engagement hole 212a due to the tension of the belt, deformation of the concave portions at both ends of the engagement tool 300, and the like, the second portion where the engagement hole 212a is provided in the belt mounting portion 210. 212 faces the center in the width direction of the luggage compartment.

  Since the belt tension is large, it is necessary that the shape of the first portion 211 and the shape of the third portion 213 in the belt mounting portion 210 are substantially symmetric. For this reason, the mounting portion 210 extends obliquely in a direction away from the rail 110 as a whole.

  Here, when moving the luggage in the luggage compartment in the front-rear direction of the truck, the belt attachment is still attached to the rail 110. That is, the belt attachment is protruding from the side wall of the luggage compartment toward the center of the luggage compartment. Here, as described above, the belt attaching portion 210 extends obliquely in a direction away from the rail 110. For this reason, when moving the luggage in the luggage compartment, the luggage easily comes into contact with the belt attaching portion 210, which leads to a reduction in work efficiency, breakage of the luggage, and the like.

  Further, in actual work, the engagement member 300 is often attached to and detached from the belt attachment portion 210 disposed in a narrow space between the side wall of the luggage compartment and the load. Therefore, when the second portion 212 of the belt attachment portion 210 faces the center in the width direction of the luggage compartment, the attachment / detachment of the engagement tool 300 is easier.

  The present invention has been made in view of the above circumstances. One of the objects of the present invention is to provide a belt attachment which does not easily hinder the movement of luggage in a luggage compartment and allows easy attachment and detachment of an engagement member at a belt end.

  Two places between the one end 51 and the other end 52 of the back side plate member 50 project from the flat plate portion 30 of the plate member 20 toward the rail 110. That is, a pair of engagement portions 10 projecting from the flat plate portion 30 toward the rail 110 are formed by appropriately bending the one end portion 51 and the other end portion 52 of the back side plate member 50. The notches formed at one end and the other end in the Z-axis direction of the protruding portion of the back side plate member 50 are a first engagement recess 11 and a second engagement recess 12.

The first engagement recesses 11 of the pair of engagement portions 10 are arranged in the X-axis direction, and the second engagement recesses 12 of the pair of engagement portions 10 are also arranged in the X-axis direction.
The central portion of the back side plate member 50 in the X-axis direction is overlapped with the flat plate portion 30, and the central portion and the flat plate portion 30 are fixed to each other by a fastening member FM such as a rivet.

  The belt attachment has an engagement maintaining member 70 for maintaining the engagement between the pair of engagement portions 10 and the engagement holes 111. The engagement maintaining member 70 is formed of a metal material, a plastic material, or the like. The engagement maintaining member 70 has a pair of maintenance members 71 arranged in each of the engagement portions 10. The maintenance member 71 is supported by the engaging portion 10 by a support shaft 71a parallel to the X axis, and the maintenance member 71 can swing around the support shaft 71a.

  One end of the holding member 71 is urged toward one side in the swing direction by the urging member 71b (FIGS. 5 and 6). In the present embodiment, the biasing member 71b is a torsion spring, but other springs can be used. Further, when a part of the maintenance member 71 abuts on the engagement portion 10 or the flat plate portion 20, the movement of the one end side of the maintenance member 71 in one swing direction is regulated (FIG. 5). At this time, a portion 71c of the other end of the holding member 71 overlaps at least a portion of the first engagement recess 11 when viewed from the X-axis direction. A portion 71c at the other end of the holding member 71 has a function of making the first engagement recess 11 shallow when viewed from the X-axis direction.

  The other ends of the pair of holding members 71 are connected to each other by an operation member 72. When the user applies a force in the Y-axis direction to the operation unit 72 in the direction of arrow A shown in FIG. 7, the operation member 72 and the pair of maintaining members 71 swing in the swinging direction against the urging force of the urging member 71b. Swing to the other. When swinging in this manner, as shown in FIG. 7, when viewed from the X-axis direction, the overlap between the part 71c at the other end of the holding member 71 and the first engagement recess 11 is reduced. Thereby, the first engagement recess 11 when viewed from the X-axis direction becomes deeper.

An example of a method for engaging the belt attachment configured as described above with the engagement hole 111 of the rail 110 will be described.
First, as shown in FIG. 7, in a state where the operating member 72 and the pair of maintaining members 71 are swinging in the other swing direction, the user operates one end edge of the engagement hole 111 in the Z-axis direction. 111 a is arranged in the first engagement recess 11 of each engagement portion 10. Subsequently, the user arranges the other edge 111 a in the Z-axis direction of the engagement hole 111 in the second engagement recess 12 of each engagement portion 10. Then, when the user stops applying a force to the operation unit 72, the first engagement recess 11 when viewed from the X-axis direction becomes shallow, as shown in FIG.

As shown in FIG. 7, when the first engagement concave portion 11 is a deep concave portion when viewed from the X-axis direction, the degree of freedom of the vertical movement of the engagement portion 10 with respect to the rail 110 is large. Therefore, it is possible to attach the engaging portion 10 to the engaging hole 111 and to remove the engaging portion 10 from the engaging hole 111. On the other hand, as shown in FIG. 6, when the first engagement concave portion 11 becomes shallow, the engagement portion 10 cannot be removed from the engagement hole 111.
Preferably, the engaging portion 10 engages with the engaging hole 111 in a state where the first engaging concave portion 11 is disposed above the second engaging concave portion 12 in order to prevent unintended disengagement. .

An engaging member 80 is detachably attached to the first engaging hole 41 or the second engaging hole 42 of the belt attaching member attached to the rail 110 (FIGS. 1 to 4).
In one example, as shown in FIGS. 4 and 8, the engagement member 80 includes a metal body 83 having a first recess 81 and a second recess 82, and a belt mounting ring connected to the body 83. 84, a swing member 85 supported by the main body 83 so as to be swingable around a support shaft 85a, and a biasing member 86 such as a torsion spring for biasing one end of the swing member 85 in one of the swing directions. And The end of the cargo handling belt is attached to the belt attachment ring 84.

For example, an example of a method of attaching the engagement tool 80 to the first engagement hole 41 will be described.
First, in a state where the user applies a force to the rocking member 85 and the rocking member 85 is rocking in the other direction in the rocking direction, the user makes one of the first engagement holes 41 in the Z-axis direction. Is disposed in the first concave portion 81. Subsequently, the user arranges the other edge 41 a of the first engagement hole 41 in the Z-axis direction in the second recess 82. When the user stops applying a force to the rocking rocking 85, the rocking member 85 is rocked by the urging member 86 in one of the rocking directions. As a result, as shown in FIG. 8, the first concave portion 81 becomes a shallow concave portion by a part of the swing member 85, so that the engagement member 80 cannot be removed from the first engagement hole 41.

  As described above, in the present embodiment, the first engagement hole 41 or the second engagement hole 42 is configured such that the engagement member 80 at the end of the belt is detachably attached. Here, it is preferable that the amount of protrusion of the belt attachment into the cargo room is small from the viewpoint of reducing obstacles to the movement of luggage in the cargo room, effective utilization of space in the cargo room, and the like. For this reason, when the plate portion provided with the first engagement hole 41 or the second engagement hole 42 extends toward the rail 110 at right angles to the flat plate portion, the attachment / detachment of the engagement member 80 at the belt end portion is performed. Work is not easy. In the present embodiment, the first inclined plate portion 31 and the second inclined plate portion 32 provided with most of the first engagement hole 41 or the second engagement hole 42 are connected to the rail 110 from the end of the flat plate portion 30. It is inclined toward. For this reason, compared with the case where the plate portion provided with the first engagement hole 41 or the second engagement hole 42 extends toward the rail 110 at right angles to the flat plate portion 30, the engagement of the belt end portion is improved. The attachment and detachment of the tool 80 is easy.

  Further, since the first inclined plate portion 31 and the second inclined plate portion 32 are provided at both ends of the flat plate portion 30 in the X-axis direction (predetermined direction), the luggage moving in the luggage room comes into contact with the belt attachment. At this time, the load contacts the first inclined plate portion 31 or the second inclined plate portion 32. Therefore, a force acts on the load from the first inclined plate portion 31 or the second inclined plate portion 32 to guide the load toward the center of the luggage compartment. That is, as compared with a case where the plate portion provided with the first engagement hole 41 or the second engagement hole 42 extends toward the rail 110 at a right angle to the flat plate portion 30, for example, the movement of the load in the luggage compartment. Hard to be an obstacle.

  In the present embodiment, the flat plate portion 30 is formed of the plate member 20 extending in the X-axis direction, and at least a part of the first inclined plate portion 31 has one end of the plate member 20 in the X-axis direction facing the rail 110 side. At least a portion of the second inclined plate portion 32 is a portion where the other end of the plate member 20 in the X-axis direction is bent toward the rail 110 side.

With this configuration, the flat plate portion 30, the first inclined plate portion 31, and the second inclined plate portion 32 are firmly fixed to each other without using a separate fastening member or the like. Therefore, even if a large force is applied to the first engagement hole 41 or the second engagement hole 42 via the belt, the first inclined plate portion 41 and the second inclined plate portion 42 are unlikely to be deformed or damaged.
Further, with this configuration, there is no protrusion such as a seam or a fastening member between the flat portion 30 and the first inclined plate portion 31. This leads to less obstruction of the movement of luggage in the luggage compartment.

  In the present embodiment, in a state where the pair of engagement portions 10 are engaged with the engagement holes 111, for example, as shown in FIG. Substantially the entire inclined plate portion 31 is arranged at a position close to the rail 10.

  As described above, it is preferable that the amount of protrusion of the belt attachment into the cargo compartment is small. That is, the flat plate portion 30 to which the pair of engaging portions 10 is fixed is arranged at a position as close to the rail 110 as possible while ensuring its strength. In the present embodiment, substantially the entirety of the first inclined plate portion 31 is arranged at a position close to the rail 110 with respect to the surface 30a of the flat plate portion 30 opposite to the rail 110 side, so that the luggage in the luggage compartment can be smoothly moved. It is very advantageous for realizing the movement.

  Further, in the present embodiment, in a state where the pair of engagement portions 10 are engaged with the engagement holes 111, for example, as shown in FIG. Substantially the entire second inclined plate portion 32 is arranged at a position close to the rail 110.

  Therefore, the first inclined plate portion 31 and the second inclined plate portion 32 are arranged on one end side and the other end side of the flat plate portion 30 attached to the rail 110 in the X-axis direction, respectively. For this reason, even when the luggage is moved to either the one side or the other side in the X-axis direction of the flat plate portion 30, a smooth movement of the luggage in the luggage compartment can be realized.

As shown in FIG. 19, the first inclined plate portion 31 can be formed by folding back one end portion 51 of the back side plate member 50. Similarly, the first inclined plate portion 32 can be formed by folding back the other end portion 52 of the back plate member 50. Also in this case, the first engagement hole 41 penetrating the first inclined plate portion 31 and the one end portion 51 is formed, and the second engagement hole 42 penetrating the second inclined plate portion 32 and the other end portion 52 is formed. You.
