TECHNICAL FIELD The present invention relates to a cutting board holder that is fitted together with a wire rack to two pins erected on a sink.

The kitchen sink may be provided with a cutting board holder on which a cutting board is placed. As such a cutting board holder, for example, Patent Document 1 discloses a storage rack for a sink (hereinafter, referred to as a storage rack) in which a mounting portion for storing sponge, detergent, etc. and a cutting board storage portion for standing a cutting board stand are integrated. ing. In Patent Document 1, the storage rack is attached to the sink by locking a round hole-shaped locking hole formed in the storage rack with a locking projection provided on the surface of the sink. This makes it possible to easily and surely attach and detach the storage rack to and from the sink.

JP, 2003-3543, A

In addition, in the configuration of Patent Document 1, the width of the interlocking hole having the shape of a duller hole is narrowed at the boundary between the large-diameter hole portion and the small-diameter hole portion, which are two holes having different sizes. As a result, when the locking projection is fitted into the small-diameter hole, the locking projection is hard to come off from the small-diameter hole. However, with such a configuration, when the storage rack is attached to the sink, after inserting the locking projection into the large-diameter hole, the wire of the storage rack is pushed in, and the narrowed boundary is passed. I have to let Therefore, the force required to attach and detach the storage rack is large, and it is difficult to say that the detachability is excellent.

In order to improve the detachability in the configuration of Patent Document 1, it is necessary to widen the width of the boundary portion of the locking hole having a sloppy hole shape. However, if the width of the boundary portion is widened, the locking projection is likely to come off the small-diameter hole when the storage rack is tilted forward due to the load of the cutting board or the vibration when the cutting board is placed.

The present invention has been made in view of the above problems, and an object thereof is to provide a cutting board holder that is detachable with a small force to enhance detachability and that is unlikely to come off from a sink.

In order to solve the above problems, a typical configuration of a cutting board holder according to the present invention is a cutting board holder that is fitted together with a wire rack to two pins erected on a sink, and a holding portion that supports the cutting board. , Two foot portions arranged in the vicinity of both ends of the holding portion, and a daruma hole provided in each foot portion and fitted with a pin, the two daruma holes having a large diameter portion and a small diameter portion oriented in the longitudinal direction. , Which are arranged in the same direction, and further provided with a protrusion projecting downward on the back surface of one of the foot portions, the protrusion being one of the wires of the wire rack fitted to the pin, of the cutting board holder. It is characterized in that it rides on a wire extending in a direction intersecting the mounting direction.

According to the above configuration, the cutting board holder can be easily attached to the sink by fitting the round hole provided in the foot portion of the holding portion to the pin. At this time, since the width between the large diameter portion and the small diameter portion of the daruma hole is not narrowed, it is possible to move the pin from the large diameter portion to the small diameter portion with a small force when attaching the cutting board holder to the sink. it can.

Also, since the large-diameter portion and the small-diameter portion of the daruma hole are arranged in the longitudinal direction, the pin from the small-diameter portion is applied from the small-diameter portion even if a force is applied to the cutting board such that the cutting board holder moves toward the sink. Does not come out. Further, in the above configuration, the protrusion is provided on the back surface of one of the two legs. This makes it possible to make the cutting board holder difficult to disengage from the sink even if a repeated load is applied when the cutting board is placed on the cutting board holder, while being removable with a small force to improve the detachability.

The protrusion may be provided on the back surface of the foot portion having the duller hole in which the small diameter portion faces the center. This makes it possible to reliably obtain the effect of making it difficult for the cutting board holder to come off the sink.

The protrusion may be inclined downward from the large diameter portion toward the small diameter portion. According to such a configuration, the protrusion easily rides on the wire of the wire rack, and the protrusion gradually presses the wire tightly as the cutting board holder is inserted, so that the above-described effect can be reliably obtained.

The small diameter portion is further provided with a locking portion projecting downward on the back surface of the foot portion provided with the diametrical hole facing the center, and the locking portion is provided when the pin is located in the small diameter portion. It is good to lock to the wire rack. As a result, the movement of the cutting board holder in the longitudinal direction can be regulated more reliably, and the above-described effect can be enhanced.

ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide a cutting board holder which is hard to be detached from the sink, while being attachable and detachable with a small force to enhance detachability.

To do.

FIG. 1 is an external perspective view of a sink 200 including a cutting board holder 100 according to this embodiment. FIG. 1A is an overall perspective view of the sink 200, and FIG. 1B is an enlarged perspective view of the vicinity of the cutting board holder 100. FIG. 2 is a perspective view showing a state where the cutting board holder 100 and the wire rack 106 are removed from the sink 200.

As shown in FIGS. 1 and 2, the wire rack 106 is configured by joining a plurality of wires, and is capable of accommodating a detergent, sponge or the like (not shown) used in the sink 200. By using the wire rack 106 as the container in this way, it is possible to suitably drain the sponge and the like after use.

As shown in FIG. 2, pins 104 a and 104 b are erected on the upper surface 102 of the sink 200 at the installation positions of the wire rack 106 and the cutting board holder 100. When the cutting board holder 100 of this embodiment is attached to the sink 200, the wire rack 106 shown in FIG. 2 is first fitted to the pins 104a and 104b. After that, by fitting the cutting board holder 100 to the pins 104a and 104b, the cutting board holder 100 of the present embodiment is installed in the sink 200 together with the wire rack 106 as shown in FIG. The detailed mounting method of the cutting board holder 100 will be described later.

FIG. 3 is an overall perspective view of the cutting board holder 100 of this embodiment. FIG. 4 is a three-view drawing of the cutting board holder 100 of this embodiment. As shown in FIGS. 3 and 4, the cutting board holder 100 of the present embodiment has a holding portion 110 that supports the cutting board 108 (see FIG. 8A). The holding unit 110 includes a front side holding unit 112, a back side holding unit 114, and a connecting unit 116.

As shown in FIG. 4, the front-side holding portion 112 and the back-side holding portion 114 are arranged parallel to the depth direction of the sink 200 (see FIG. 1) and are connected by a connecting portion 116 arranged at the bottom. There is. Thus, when the cutting board 108 is placed on the connecting portion 116, the side surface of the cutting board 108 is supported by the front side holding section 112 and the back side holding section 114 so as not to fall.

As shown in FIGS. 3 and 4, two legs, that is, a right leg 120a and a left leg 120b are arranged near both ends of the holding unit 110, that is, on both sides of the holding unit 110. The right foot portion 120a and the left foot portion 120b are provided with daruma holes 122 that fit with the pins 104a and 104b (see FIG. 2). Each of the two duller holes 122 includes a large-diameter portion 122a and a small-diameter portion 122b coupled to the large-diameter portion 122a.

FIG. 5 is a detailed view of the Daruma hole. FIG. 5A is a diagram illustrating the daruma hole 122 of the present embodiment, and FIG. 5B is a diagram illustrating the conventional daruma hole 10. As shown in FIG. 5A, in the present embodiment, the two bursa holes 122 are arranged such that the large diameter portion 122a and the small diameter portion 122b are oriented in the longitudinal direction of the cutting board holder 100 (the left and right direction of the sink 200). There is. That is, the large-diameter portion 122a and the small-diameter portion 122b are arranged (joined) along the longitudinal direction of the cutting board holder 100. Moreover, in the two daruma holes 122, the large diameter portion 122a and the small diameter portion 122b are arranged in the same direction. Specifically, in the present embodiment, the large diameter portion 122a is arranged on the left side and the small diameter portion 122b is arranged on the right side of the daruma hole 122 (see FIG. 4).

FIG. 6 is a view for explaining the attachment of the cutting board holder 100 to the sink 200. When the cutting board holder 100 is attached to the sink 200, the wire rack 106 is attached to the pins 104a and 104b erected on the upper surface 102 of the sink 200 shown in FIG. 6A as shown in FIG. 6B. At this time, the wire rack 106 lightly hooks the wire on the pins 104a and 104b. After that, as shown in FIG. 6C, the pins 104a and 104b are arranged in the large diameter portion 122a of the bursa hole 122 of the cutting board holder 100, and as shown in FIG. The cutting board holder 100 is slid in the longitudinal direction (to the right in this embodiment) so as to be arranged in the small diameter portion 122b. As a result, the cutting board holder 100 is installed in the sink 200 together with the wire rack 106.

Here, as shown in FIG. 5B, in the conventional Daruma hole 10, the width of the boundary portion 12c between the large diameter portion 12a and the small diameter portion 12b is narrowed. Therefore, a large force is required when moving the pin (not shown in FIG. 5B) from the large diameter portion 12a to the small diameter portion 12b. On the other hand, as shown in FIG. 5A, in the daruma hole 122 of the present embodiment, the width between the large diameter portion and the small diameter portion 122b is not narrowed. Therefore, when the cutting board holder 100 is attached to the sink 200, the pins 104a and 104b can be moved from the large diameter portion 122a to the small diameter portion 122b with a small force, and the cutting board holder 100 can be easily attached to the sink 200.

Further, in the cutting board holder 100 of the present embodiment, the two duller holes 122 are arranged with the large diameter portion 122a and the small diameter portion 122b oriented in the longitudinal direction and in the same direction. As a result, the attaching/detaching direction of the cutting board holder 100 with respect to the sink 200 becomes the longitudinal direction of the cutting board holder 100 as described above. Therefore, the pins 104a and 104b do not come off from the small diameter portion 122b even if a force that is directed forward, that is, a force that the cutting board holder 100 is directed toward the sink 200 is applied by the load of the cutting board 108 or the like.

Here, in the plan view of the cutting board holder 100 shown in FIG. 4, the duller hole 122 of the left foot portion 120b arranged on the left side is arranged so that the small diameter portion 122b faces the side away from the center of the cutting board holder 100. .. On the other hand, the duller hole 122 of the right foot 120a arranged on the right side is arranged so that the small diameter portion 122b faces the center of the cutting board holder 100. As a feature of this embodiment, of the two foot portions (the right foot portion 120a and the left foot portion 120b), the right foot portion 120a (the foot portion provided with the daruma hole 122 in which the small diameter portion 122b faces the center). A protrusion 124 is provided on the back surface of one foot) (see FIG. 7).

FIG. 7 is a diagram showing a state in which the right foot 120a is observed from below. As shown in FIG. 7, on the back surface of the right foot portion 120a in which the small-diameter portion 122b faces the center, the protruding portion 124 that rides on the wire of the wire rack 106 (illustrated by hatching in FIG. 7). Is protruding downward.

More specifically, as shown in FIG. 6B, in the wire forming the wire rack 106, a foot portion having a protrusion 124 formed on the back surface, that is, a portion on the side where the right foot portion 120a is arranged, The wire extending in the direction intersecting the mounting direction of the cutting board holder 100 serves as the riding portion 106a. Then, as described above, the cutting board holder 100 is slid in the longitudinal direction (rightward in this embodiment) so that the pins 104a and 104b are arranged in the small diameter portion 122b of the blunt hole 122, as shown in FIG. The protruding portion 124 is in a state of riding on the riding portion 106a.

Then, the riding-on portion 106a is pressed and fixed to the upper surface 102 of the sink 200. That is, the protrusion 124 enters like a wedge between the pin 104a and the ridden portion 106a (wire). As a result, the cutting board holder 100 and the wire rack 106 can be firmly fixed, and rattling and movement of these can be restricted.

What is important here is to fix only the right foot portion 120a, that is, the foot portion provided with the daruma hole 122 in which the small diameter portion 122b faces the center.

FIG. 8 is a diagram illustrating a load applied to the cutting board holder 100. FIG. 8A shows a state in which the cutting board holder 100 on which the cutting board 108 is placed is observed from the front, and FIG. 8B shows the cutting board holder 100 in which the cutting board is not shown is observed from above. 8C shows a state, and FIG. 8C shows the AA cross section and the BB cross section of FIG. 8B.

As shown in FIG. 8A, when a cutting board is placed on the holder 110, a downward load N (impact load) is applied to the cutting board holder 100. This load N is applied to each of the right foot 120a and the left foot 120b as the loads D1 and D2 dispersed in the left and right as shown in FIG. 8B. That is, stress is applied to the right foot 120a and the left foot 120b in the outward direction (the direction that spreads to the left and right). After that, when the stress is relieved (when the load becomes static), the right foot 120a and the left foot 120b move inward.

FIG. 9: is a figure which illustrates the cutting board holder of a comparative example. FIG. 9A illustrates a cutting board holder 20a in which neither of the two foot portions 22a and 22b has a protrusion. As shown in FIG. 9(a), when neither of the two foot portions 22a/22b has a protrusion, when the cutting board holder 20a is subjected to an outward force like loads D1/D2, The portions 22a and 22b can move in the outward direction, and can move inward when the stress is relieved and the inward force is applied.

That is, like the cutting board holder 20a shown in FIG. 9(a), when neither of the two foot portions 22a and 22b is provided with a protrusion, both when stress is applied and when it is relaxed. Since the movement of the foot portions 22a and 22b is not restricted, the foot portions 22a and 22b can freely move largely. When the foot first spreads, the right foot 22a cannot move because the pin hits the end of the small diameter portion, and only the left foot 22b moves. When the foot narrows, the left and right foot portions 22a and 22b move uniformly. After that, theoretically, the left and right foot portions 22a and 22b will spread or narrow at that position (without moving to the left and right), but due to error, they will gradually move to the left and right, and eventually the large diameter of the sloppy hole. The part may move to the position of the pin, and the cutting board holder 20a may come off the pin.

FIG. 9B illustrates a cutting board holder 20b in which protrusions 26a and 26b are provided on both of the two legs 24a and 24b. As shown in FIG. 9B, when the projections 26a and 26b are provided on both of the two foot portions 24a and 24b, the wire rack 106 is pressed and fixed by the left and right foot portions 24a and 24b. This secures both feet, and at first glance it looks solid. However, when the left and right foot portions 22a and 22b are spread by the loads D1 and D2, the right foot portion 24a cannot be moved because it is tightened more strongly, whereas the left foot portion 24b is loosened. I can move.

Then, when the foot narrows, this time, the force with which the protrusion 26a of the right foot 24a comes off is smaller than the force with which the protrusion 26b of the left foot 24b rides on the wire rack 106. Therefore, the left and right legs 24a and 24b cannot return to the initial positions, and the protrusions 26a and 26b are in a state of sliding down from the wire rack 106. Then, by repeatedly taking out and placing the cutting board, the cutting board holder 20b may gradually shift to the left, and the cutting board holder 20b may come off the pin.

On the other hand, in the cutting board holder 100 of the present embodiment shown in FIG. 8C, the protruding portion 124 is provided only on the back surface of the right foot portion 120a in which the small diameter portion 122b is provided with the daruma hole 122. ing. As a result, the right foot 120a is restricted from moving to the right, and the left foot 120b is not restricted from moving to the left or right.

According to the above configuration, when the cutting board holder 100 is subjected to an outward force such as the loads D1 and D2, the protrusion 124 of the right foot 120a is pressed against the riding portion 106a of the wire rack 106. This restricts movement. Therefore, only the left foot 120b moves outward (to the left). Then, when the stress is relaxed, the left foot 120b freely moves inward (to the right), so that the right foot 120a is not pulled and the left foot 120b returns to the initial position. Therefore, the position of the cutting board holder 100 does not shift even if any force is applied to bend the cutting board holder 100 outward or to move inward when the bending returns. Therefore, it is possible to suppress the movement of the cutting board holder 100 due to the repeated load when the cutting board is placed, and to prevent the cutting board holder 100 from coming off the sink.

Further, as can be seen with reference to FIGS. 8B and 8C, in the present embodiment, the protrusion 124 has a shape inclined downward from the large diameter portion 122a toward the small diameter portion 122b. Accordingly, when the cutting board holder 100 is attached, the protrusions 124 act like wedges to press the wire rack 106 against the upper surface 102 of the sink 200. For this reason, the protrusion 124 does not hinder the movement when the cutting board holder 100 is attached to the sink 200, and can be pressed reliably. Similarly, no strong force is required when removing the cutting board holder 100. Since it is possible to attach and detach with a small force as described above, it is possible to enhance the detachability.

FIG. 10 is a diagram illustrating an additional configuration of the right foot 120a. 10A is an enlarged plan view of the right foot 120a, and FIG. 10B is an arrow view of the right foot 120a of FIG. 10A as observed from the E direction. As shown in FIGS. 10(a) and 10(b), in the present embodiment, the locking portion 126 is further provided on the back surface of the right foot portion 120a provided with the daruma hole 122 in which the small diameter portion 122b faces the center. It is provided.

Specifically, as shown in FIG. 10(a), a locking portion 126 protruding downward is provided at the outermost position on the back surface of the right foot 120a, as shown in FIG. 10(b). There is. The locking portion 126 is shown in FIG. 10B when the pins 104a and 104b are located in the small diameter portion 122b, that is, when the cutting board holder 100 is attached to the sink 200 as shown in FIG. 6D. The wire rack 106 is locked as shown in FIG. As a result, the movement of the right foot 120a to the left (movement of the pin 104a to the large diameter portion 122a) can be more reliably regulated, so that the position of the cutting board holder 100 due to the repeated load when the cutting board is placed. It is possible to suppress the deviation more suitably and enhance the above-mentioned effects.

The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to such examples. It is obvious to those skilled in the art that various changes or modifications can be conceived within the scope described in the claims, and naturally, they also belong to the technical scope of the present invention.
