Description

  The present invention relates to an improvement in a toilet lid of a Western style toilet.

  Western-style toilets are toilet bowls, toilet seats, and toilet lids. In recent years, more and more advanced functions have been developed, and many products are equipped with functions such as automatic opening and closing of toilet lids and automatic toilet flushing functions. It is also a product that is becoming increasingly popular. Patent Documents 1 to 3 describe a handle attached to a toilet lid, toilet seat or toilet lid cover.

  The concept of providing a handle on the toilet lid was not unusual for Japanese-style toilets. Most of the current Japanese style toilet bowls are made of ceramics and their toilet bowls remain open, but the wooden Japanese style toilet bowls seen until the Meiji period are closed with a wooden lid, A handle for opening and closing was attached. On the other hand, Western-style toilets came into Japan with toilet seats and toilet lids, but in Japan it is said that they came to be used as they were, in the sense of covering odors.

  The reason why the handle was attached to the lid of the wooden Japanese-style toilet that has been used in Japan so far is that the lid is a flat plate. It seems that it is difficult. On the other hand, in Western style toilets, the toilet lid is pivotally supported at one end of the toilet bowl so that it can be opened and closed directly or through the base of the toilet seat. It can be rotated from the horizontal posture to the vertical posture, and it is not difficult to open and close without a handle like a removable lid of a wooden Japanese toilet bowl.

  Although there is no particular problem with the opening / closing operation itself, the reason why a handle is provided on the toilet lid of a Western-style toilet is described in Patent Document 1 as follows. If water is poured with the lid closed, the sewage will bounce back and stick to the back of the toilet seat and cover (toilet lid). The reason why it is unsanitary is pointed out, and Patent Document 2 points out the problem that it is unsanitary when the hand touches the toilet bowl and is difficult to grasp because the hand is opened and closed by hand. . Patent Document 3 describes that a handle is attached to the toilet seat or toilet lid cover instead of attaching the handle directly to the toilet seat or toilet lid, and the same problem is pointed out as the reason for providing the handle. Yes.

  As shown in FIG. 7, the handle described in Patent Document 1 has a suction cup 21 attached to one end thereof, the suction cup 21 is adsorbed on the back side of a toilet seat or cover (toilet lid), and the handle arm is extended to the side of the toilet. Hold 22 in your hand and raise and lower it. On the other hand, in patent document 2, patent document 1 is taken up as a prior example, and the problem is pointed out as follows.

  That is, regarding the handle of the toilet lid, when a plate with a straight handle body is attached to the curved upper lid, the handle portion protruding from the toilet bowl is directed obliquely downward, and the handle facing downward When you try to grab the handle, it is thought that the finger on the underside of the handle touches the toilet, and if the handle is facing downward, it is difficult to grip, and if the handle is thick, the toilet lid fits on the toilet seat As a result, there is a gap between the toilet seat and the toilet lid.

  In Patent Document 2, in order to solve the above problem, a thin plate-like handle body 31 is used as shown in FIG. 8, and this is applied to the bottom surface of the toilet lid to sandwich a part of the outer edge, and the handle portion 32 is attached to the toilet bowl. In contrast, a toilet lid handle that protrudes laterally is proposed. According to Patent Document 2, according to this handle, when the toilet lid of the toilet is opened and closed, the handle portion 32 of the handle protrudes laterally or slightly obliquely upward with respect to the toilet, so that the finger touches the toilet. The effect of being easy to grasp is emphasized.

  By the way, in the case of a wooden Japanese style toilet bowl, it is only necessary to grasp the handle and remove the toilet lid from the toilet bowl, so the handle need only be provided on the upper surface of the toilet lid, and the attachment position of the handle is particularly problematic. However, in Western-style toilets, the toilet lid must be taken into account when the posture changes from a horizontal posture with the toilet bowl closed to a vertical posture with the toilet bowl open, and the handle is provided on the upper surface of the toilet lid. It does not mean that it is necessary. If the handle protrudes from the surface of the toilet lid, it causes other problems such as obstruction when maintaining a standing posture in a vertical posture.

  Nonetheless, as described in Patent Documents 1 and 2, when a handle is provided to extend to the right side (or left side) of the toilet, when the handle is lifted when the toilet lid is opened In addition, the wrist is twisted as the toilet lid changes from a horizontal posture to a vertical posture.

  On the other hand, when using a normal Western-style toilet, in most cases, the toilet room is opened by entering the front door of the toilet and stands in front of the toilet, as described in Patent Documents 1 and 2. When the toilet lid handle protrudes to the right side, there is a problem that it is difficult for left-handed people, and some toilets have a structure in which the right or left door of the toilet is opened to enter the toilet. However, it is not always advantageous to provide the handle so as to protrude in the right lateral (or left lateral) direction.

  By the way, considering the meaning of providing a handle on the toilet lid, in the case of a Western-style toilet, there is a cause in a problem peculiar to the Western-style toilet that the toilet seat cannot be seen if the toilet bowl is closed with the toilet lid. I think that. This is because if the toilet seat is dirty, the toilet cannot be used.

  Of course, such a situation is not a problem in a general toilet, but it can be a toilet in public facilities such as public toilets, hospitals, and nursing homes. As pointed out in Patent Document 1, if the toilet seat is dirty, it is uncomfortable, unsanitary, and difficult to grasp. In the unlikely event that you need to grasp the toilet accessories with your hands without knowing the state, it seems that it may be difficult to eliminate the discomfort caused by grabbing the toilet accessories with your hands .

JP 2000-107079 A JP 2009-279027 A 6-66496

  The problem to be solved is that in the concept of grasping and lifting the handle attached to the toilet lid instead of grasping and opening the toilet lid, the discomfort caused by the act of grasping cannot be resolved. When the lid is raised in a vertical position, the wrist may be unjustly twisted, and when the handle is extended laterally, there is a problem in the usability.

The present invention is a western toilet toilet lid provided with a support on the front outer edge of the toilet lid,
The support is bulged with a constant bulge length in a direction substantially parallel to the upper surface of the toilet lid within the range of the rising height of a rib formed to model the outer edge of the toilet lid, and The support is a protruding edge with a constant thickness, and the outer shape of the chevron is trimmed by a smooth curved edge to match the design and shape of the toilet lid. The through-hole is opened.

  In the present invention, when the toilet lid is closed, the toilet lid is moved from the horizontal posture to the vertical posture without twisting the wrist by pushing the lower surface of the chevron-shaped support protruding from the front of the toilet lid and pushing it up as it is. It is possible to open the toilet bowl by converting it into, and since the support position is the front face of the toilet lid, the left and right fingers can be used without distinction.

  Furthermore, the part where the hand is attached to the support may be only a part of the tip of the lower surface of the support, and by setting the support in a chevron shape, the contact area with the finger can be reduced as much as possible. In this case, it is possible to reduce the discomfort, and it can be confirmed that the finger attached to the lower surface does not touch the tip of the toilet seat through the viewing window opened at the protruding edge.

It is a figure which shows one Example of the western style toilet to which this invention is applied. It is a figure which shows the Example of the toilet lid which formed the support integrally. (A)-(c) is a figure which shows the operation point in the case of pushing up a toilet lid with the finger | toe attached to the support and opening a toilet bowl. It is a figure which shows one example of a detachable support. It is a figure which shows the point which attaches a detachable support to a toilet lid. It is a figure which shows the toilet lid which attached the detachable support. It is a figure which shows the handle for toilet lids described in patent document 1. FIG. It is a figure which shows the handle for toilet lids described in patent document 2. FIG.

  Hereinafter, a specific configuration of the present invention will be described in detail with reference to the drawings. In FIG. 1, the toilet of the western toilet according to the present invention includes a toilet bowl 1, a toilet seat 2, and a toilet lid 3, and although not shown in detail, a cleaning device, a toilet seat heat retention device, and the like may be provided. is there. Some Western-style toilets have an automatically openable / closable toilet lid, but the toilet lid to which the present invention is applied is of a type that is manually opened and closed.

  FIG. 2 shows the structure of the toilet lid of the warm water flush toilet seat. As for the toilet lid 3, the shape of both outer edges is modeled by a hyperbola, a curved edge is formed at the tip part, and the base part of the parallel part which extended both the hyperbola as shown in FIG. Yes. Alternatively, it is attached to the toilet seat 2 so as to be able to rise and fall.

  On the outer edge of the toilet lid 3, a rib 4 that rises at a constant height is formed as shown in FIG. 2 in the shape of the outer shape of the toilet lid, giving the toilet lid 3 a three-dimensional effect. In the present invention, within the range of the rising height of the rib 4 on the front surface of the toilet lid 3, a finger support 5 is provided on a part of the rib 4 so as to protrude from the front surface. The support 5 is a projecting edge with a certain thickness (PROJECTION), and the outer shape of the chevron is trimmed with a smooth curved edge to match the design and shape of the toilet lid, and the chevron shape is imitated in the surface of the projecting edge. A viewing window 6 is opened. The protruding length of the support 5 must protrude further in the front direction than the front end position of the toilet seat 2 covered with the toilet lid 3.

  In the present invention, the support 5 may have a size necessary for supporting the lower surface with fingers, and is not a so-called handle for grasping with a hand. The viewing window 6 opened on the surface of the protruding edge is designed to minimize the contact area with the finger, and the finger attached to the lower surface of the protruding edge of the support 5 through the viewing window 6 does not touch the outer surface of the front end of the toilet seat 2. It is a through-hole for confirming, and not a hole for inserting a finger.

  In FIG. 3 (a), when using a Western-style toilet equipped with a toilet lid according to the present invention, enter the toilet room and stand in front of the toilet, supporting the belly of the index finger F on the right or left hand, and attaching it to the lower surface of 5 Then, it is pushed up as it is (see FIG. 3B), and the toilet lid 3 is erected in a vertical posture (see FIG. 3C). As a result, the toilet seat 2 is opened, and it is possible to check whether the toilet seat 2 is dirty by visually observing the state of the toilet seat 2, and whether the toilet seat 2 can be used as it is.

  In the present invention, the overhang position of the support 5 is set in front of the toilet lid 3 in order to enable the push-up operation of the toilet lid 3 regardless of whether the finger of the right hand or the finger of the left hand as described above. For the operation, for example, the belly of the index finger F is simply attached to the lower surface of the support 5 and pushed up as it is, and the toilet lid 3 is moved from a horizontal posture to a vertical posture as shown in FIGS. 3 (a) to 3 (c). When the posture changes, the contact position of the finger F with respect to the support 5 changes from the belly of the index finger F to the back of the finger, and there is no need to bend the arm or twist the wrist for lifting the toilet lid 3, Therefore, there is no burden on the arms and wrists.

  This means that when the support overhanging position is set to the right or left side of the toilet lid, the hand handled as described above is not limited to the right or left hand, but the toilet lid is directed from the horizontal posture to the vertical posture. As your posture changes, you must bend your arms forcibly.

  Also in the present invention, the handle 5 is handled in the same manner as the handles described in Patent Documents 1 and 2, and when the operator wants to lift the toilet lid by holding the support 5 or by inserting a finger into the viewing window 6, Since it is necessary to twist the wrist when trying to lift the lid 3, it is desirable to set the support in a shape that is difficult to grasp, but in order not to impair the design of the Western toilet, the design of the support 5 Is important.

  From this point of view, the shape of the support 5 is a mountain shape with a constant thickness formed by a smooth curve on the front surface of the toilet lid 3 as shown in the figure, and a similar viewing window 6 is opened in the inside. It is set to 1 and the cavity of the mold for molding of the toilet lid 3 is provided with a molding cavity for support (both not shown), and the molding of the support 5 together with the molding of the toilet lid 3 Because of its improved design and excellent design, it can be expected to affect the use of the toilet and be used carefully by the user.

  According to the present invention, the support is not limited to being formed integrally with the toilet lid, but can be detachably attached to an existing toilet lid. FIG. 4 is an example of the support provided to the market as a part. In FIG. 4, the detachable support 10 is provided with clamps 12 and 12 at both ends of a round bar 11 bent into a mountain shape with a smooth curve.

  The clamp 12 is fixed with the front rib of the toilet lid sandwiched therebetween, and in this embodiment, a U-shaped piece 13 having a gap with an open surface is bent into a mountain shape with a smooth curve. The round bar 11 is fixed to both ends, and a tightening screw 14 is screwed from the outer end surface of the piece 13 toward the gap.

  When attaching the detachable support 10 to an existing toilet lid, as shown in FIG. 5, the rib 4 on the front of the toilet lid 3 is inserted across the gap between both pieces 13 with the toilet lid open, A tightening screw 14 is screwed into the piece 13 from the inside, and the round bar 11 bent into a mountain shape is fixed to the rib 4 on the front surface of the toilet lid 3 as a detachable support 10.

  By attaching the detachable support 10 to the toilet lid of an existing Western-style toilet as shown in FIG. 6, a round bar 11 bent into a mountain shape and a space surrounded by the outer edge of the toilet lid becomes a viewing window 6, The toilet lid can be opened and closed by the same handling as the support integrated with the lid 3.

  The present invention can be widely applied to Western-style toilets, but is suitable for use in public toilets and toilets used by an unspecified number of people such as public facilities, hospitals, nursing homes, and stores.
