Description

  The present invention relates to a pinching attachment type protruding device that is attached to a body to be attached by sandwiching the body to be attached such as a toilet seat and is used as a handle for a toilet seat or the like.

  When a Western-style toilet is used for a small male, a part of the urinated urine is often applied to the upper end surface of the toilet rim, which causes a sense of filth when swinging the toilet seat.

  Therefore, Patent Document 1 below discloses a toilet seat handle that is attached to a toilet seat by sandwiching an inner peripheral edge portion and an outer peripheral edge portion of the toilet seat. According to this structure, a handle can be attached to a toilet seat, without forming a screw hole etc. in a toilet seat.

  However, the holding strength is weak because the metal wire is held using the elastic force of the metal wire or the biasing force of the spring. Excessive force is likely to be applied to the handle, especially when you are in a hurry or endured urine. If one of the clamping pieces is configured with a nut to increase the clamping strength, only the lower end of the toilet seat will be clamped, so that the clamping force is not sufficient, and the nut is caused by vibration during butterfly movement. Each time it is loosened, it is necessary to tighten the nut with a spanner or the like, which is complicated.

  In the following Patent Document 2, one of the pair of clamping pieces is fixed to the base plate with a bolt and a wing nut, thereby facilitating tightening when the bolt is loosened.

However, since the arm of the bending moment applied to the clamping piece is relatively long, it cannot be said that the clamping force is sufficient, and the wing nut is exposed, so it does not look good.

  In view of such problems, the object of the present invention is to hold the object to be clamped relatively strongly, and can easily tighten it even if the screw for maintaining the clamping is loosened, and has a good appearance. An object of the present invention is to provide a sandwich mounting type protruding tool.

One aspect of the present invention will be described with reference to the reference numerals in the drawings. In the clamping attachment type projecting tool attached to the attached body by sandwiching the attached body (2),
A hollow body (40) having a hollow portion and having an open end at the tip of the hollow portion;
A rear portion inserted into the hollow portion with play, and a front portion connected to the rear portion, the front portion including a projecting portion (32) corresponding to a part of the open end of the hollow body; An adjuster (30) formed with a tip surface (31) for directly or indirectly pressing the first part (2b) of the attached body;
The tip of the attached body formed with a hook-shaped portion (21) for engaging with the second portion (2a) opposite to the first portion and pressing the second portion directly or indirectly And a base end (22) inserted into the hollow portion, and a base portion (23) connecting the distal end portion and the base end portion to a portion on the base end portion side. ) And the adjuster protrudes in a direction in which the projecting portion (32) separates from the base portion (23) in a state where the rear portion is inserted into the hollow portion. Has been established,
A screw (51) is integrally formed with one of the hollow body (40), the part opposite to the opening end and the base end part (22), with the shaft facing the other side. The nuts (50) that are fitted so as to rotate and the screws are integrally formed, and the screw holes that are fitted so as not to rotate or that are screwed with the screws are integrally formed. ing.

  According to the configuration of the first aspect, simply by rotating the hollow body (40), the screw is screwed into and screwed into the nut or the screw hole, whereby the open end of the hollow body is formed. (41) presses the protruding portion (32) of the adjuster directly or indirectly so that the attached body (2) is sandwiched between the adjuster (30) and the hook (20). Even if the tightening of the screw is loosened due to vibration of time, this clamping can be easily reinforced.

  Further, the rear portion of the adjuster (30) is loosely inserted into the hollow body, and the protruding portion (32) is protruded in a direction away from the base portion (23) in the loosely inserted state, Since the projecting portion (32) directly or indirectly presses a part of the open end (41) of the hollow body (40), the tip surface of the adjuster (30) and the hook of the hook The first part (2b) can be firmly held between a part of the base part (23).

  Furthermore, since the hollow body (40) covers the rear part of the hook (20) and the rear part of the adjuster (30), the hollow body (40) is good in appearance and shortens the overall length of the sandwich mounting type projecting tool (10). can do.

  Other objects, configurations and effects of the present invention will become apparent from the following description.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 4, a toilet seat 2 and a lid 3 are pivotally supported on one end side of the upper end of the toilet body 1 so as to be swingable. The toilet seat 2 has a substantially ring shape, and a handle 10 to which the clamping attachment type projecting device of the present invention is applied is attached to a side portion thereof.

  FIG. 1 is a perspective view showing a handle 10 attached to the toilet seat 2 together with a part of the toilet seat 2. FIG. 2 is an exploded perspective view of the handle 10 of FIG. 3A to 3D are respectively a plan view of the handle 10, a longitudinal sectional view taken along line BB in FIG. 3A, a right side view of the handle 10, and a left side surface of the handle 10. FIG. It is a perspective view of the hook 20, the adjuster 30, and the knob 40 which comprise. 3A is a plan view of the handle 10, and FIG. 3B is FIG. 3A. 4A and 4B are a left side view and a right side view of the handle 10 shown in FIG. 3, respectively.

  The handle 10 includes the hook 20, the adjuster 30, and the knob 40 as main components, and is integrally formed of synthetic resin by injection molding.

  A hook-shaped portion 21 is formed at the tip of the hook 20 and is engaged with the inner peripheral side edge 2 a of the toilet seat 2 inside the hook-shaped portion 21. The front end surface 31 of the adjuster 30 corresponds to the outer peripheral side edge 2 b of the toilet seat 2. When the knob 40 is rotated clockwise, the knob 40 moves to the bowl-shaped portion 21 side, the distal end surface 41 of the knob 40 presses the flange 32 of the adjuster 30, and the distal end surface 31 of the adjuster 30 is the outer peripheral edge 2b. Press.

  The movement of the knob 40 in the axial direction with respect to the hook 20 is performed by the following configuration. That is, the nut 50 is inserted into the notch 221 of the nut holding portion 22 formed at the base end portion of the hook 20, while the head of the bolt 51 is inserted into the recess 42 formed at the rear end portion of the knob 40. When the knob 40 is rotated, the bolt 51 rotates integrally with the knob 40. At this time, when the bolt 51 is screwed into the nut 50, rotation of the nut 50 is blocked by the nut holding portion 22, so that the knob 40 is screwed together with the bolt 51 with respect to the hook 20.

  In detail, the configuration related to the bolt 51 and the nut 50 is formed with notches 222 and 223 on the rear side and the front side of the notch 221 in the nut holding portion 22, respectively, so that the bolt 51 penetrates the nut 50. It is possible. In order to facilitate assembly, on the back side of the inner wall surface of the recess 42, as shown in FIG. 2, there are three thin linear protrusions 43 extending in the insertion direction of the bolt 51 at equal intervals of 120 °. The bolt 51 is formed so that the head portion of the bolt 51 can be easily inserted into the recess 42 to some extent, and when the bolt 51 is further inserted, the bolt 51 is difficult to be removed.

  Such a configuration is the same for the inner wall surface of the notch portion 221 of the nut holding portion 22, and thin linear convex portions 224 extending in the insertion direction of the nut 50 are formed on the upper and bottom surfaces facing each other in the notch portion 221. The nut 50 is formed so that the nut 50 can be easily inserted into the cutout portion 221 to some extent.

  A hole 44 into which the bolt 51 is inserted is formed in the bottom surface of the recess 42 of the knob 40. Four ribs 44 are formed at equal intervals of 90 ° between the cylindrical inner peripheral surface of the knob 40 and the outer peripheral surface of the concave portion 42 in order to reduce the weight of the knob 40 and reduce the cost and to reinforce the concave portion 42. Has been.

  Next, in the hook 20, the hook portion 21 and the nut holding portion 22 are connected by the base portion 23, and the hook portion 21 side corresponds to the lower surface of the toilet seat 2. A guide rail portion 24 having a T-shaped longitudinal section is formed on the nut holding portion 22 side of the base portion 23 so that the adjuster 30 can be guided in the longitudinal direction of the hook 20. A rectangular stopper 241 is formed at the tip of the guide rail portion 24. On the other hand, a guided portion 34 having a longitudinal C-shaped section is formed on the bottom surface side of the adjuster 30, and the guide rail portion 24 is loosely fitted thereto. A hollow portion 35 is formed above the guided portion 34 to reduce the cost by reducing the weight of the adjuster 30.

  On the bottom surface of the base portion 23, ribs 25 project from the front end to the rear end along the center line thereof, thereby making the base portion 23 thinner and lighter and ensuring the bending strength of the base portion 23. Is possible.

  Next, an example of the operation of attaching the handle 10 configured as described above to the toilet seat 2 will be described.

  The nut 50 is inserted into the notch 221 of the nut holding part 22, the bolt 51 is inserted into the hole 44 of the knob 40, and the head 511 of the bolt 51 is inserted into the recess 42 of the knob 40. Further, the guided portion 34 of the adjuster 30 is engaged with the guide rail portion 24 of the hook 20.

  In this state, the toilet seat 2 is disposed on the base portion 23, the knob 40 is extrapolated so as to cover the rear portion of the hook 20 and the rear portion of the adjuster 30, and the knob 40 is rotated clockwise so that the bolt 51 is connected to the nut 50. Combine.

  As a result, the knob 40 is screwed toward the bowl-shaped portion 21 side, the flange 32 of the adjuster 30 is pressed by the distal end surface 41 of the knob 40, and the distal end surface 31 presses the outer peripheral side edge 2 b of the toilet seat 2. As a result, the toilet seat 2 is sandwiched between the hook-shaped portion 31 of the hook 20, the tip surface 31 of the adjuster 30, and the portion of the hook 20 near the adjuster 30.

  In this way, the knob 40 functions as a spanner for the bolt 51, and the clamping between the hook-shaped portion 21 and the distal end surface 31 can be strengthened simply by rotating the knob 40. Even if the tightening is loosened, this clamping can be easily reinforced.

  Further, since the upward projecting flange 32 of the adjuster 30 loosely inserted into the knob 40 is pressed by the front end of the knob 40, the base 23 side by the tip end surface 31 of the adjuster 30 with respect to the outer peripheral side edge 2 b of the toilet seat 2. The pressing moment is relatively strong, and the toilet seat 2 can be clamped more firmly than when the lower end of the adjuster 30 is pressed.

  Furthermore, since the knob 40 covers most of the rear portion of the hook 20 and the adjuster 30, it looks good and the length of the handle 10 is made shorter than when the opening end of the knob is on the opposite side (Patent Document 2). can do.

  Here, in FIG. 4, since the shapes of the inner peripheral surface and the outer peripheral surface of the toilet seat 2 are not similar, the tangent of the inner peripheral surface of the toilet seat 2 and the tangent of the outer peripheral surface are slightly shifted from parallel at the attachment position of the handle 10. . That is, the outer peripheral side edge 2b of the toilet seat 2 is slightly deviated from a right angle with respect to the longitudinal direction of the hook 20. For this reason, it becomes a cause by which the toilet seat clamping by the bowl-shaped part 21, the front end surface 31, and the base part 23 becomes weak.

  However, this problem is solved with the following configuration.

  That is, as shown in FIG. 3A, the surface 33 of the flange 32 of the adjuster 30 corresponding to the tip 41 of the knob 40 is a smooth convex surface like the surface of the convex lens. More specifically, with respect to the opening circle tangent corresponding to the flange 32 of the adjuster 30 at the opening end 41 portion of the knob 40, the distance between the tangent and the surface 33 increases as the distance from the contact increases. ing. Further, there is play between the outer peripheral surface in the knob 40 of the adjuster 30 and the inner peripheral surface of the knob 40 and between the guide rail portion 24 and the guided portion 34.

  With such a configuration, by pressing the convex surface 33 with the tip surface 41 of the knob 40, the direction of the adjuster 30 is shifted according to the above-described shift, and the pressing area of the tip surface 31 against the outer peripheral side edge 2b of the toilet seat 2 is widened. Thus, the clamping by the bowl-shaped portion 21, the distal end surface 31, and the base portion 23 can be further strengthened.

  Further, the linear protrusions 43 and 224 and the stopper 241 can prevent the bolt 51, the nut 50, and the adjuster 30 from falling even if the components are inclined during the assembly, so that the assembly is easy.

  FIG. 5 (A) shows a longitudinal section of the handle 10A according to the second embodiment of the present invention.

  In this handle 10A, a screw hole 50A corresponding to the nut 50 of the first embodiment is formed in the rear end portion 22A of the hook 20A, while the tube of the knob 40A is directed to the front end of the knob 40A at the rear end portion of the knob 40A. A bolt part 51 </ b> A protrudes concentrically with the part.

  According to this configuration, since the screw hole 50A is integrally formed with the hook 20A and the bolt portion 51A is integrally formed with the knob 40A, the assembly of the handle 10A is easier than in the case of the first embodiment.

  Further, the stopper plate 241 is not formed on the guide rail portion 24, and the adjuster 30 can be engaged with the guide rail 24 from the front side of the hook 20A.

  Further, the ribs 25 as shown in FIG. 3 are not formed on the bottom surface of the hook 20A. The thickness of the hook 20A is increased in order to increase the bending strength, and the bottom surface of the longitudinal section is formed in an arc shape.

  FIG. 5B shows a longitudinal section of the handle 10B according to the third embodiment of the present invention.

  In this handle 10 </ b> B, the bolt 51 </ b> A and the screw hole 50 </ b> A are formed at positions opposite to those in the second embodiment. That is, the bolt 51A protrudes rearward from the rear end portion 22B of the hook 20B, while the screw hole 50A is formed at the rear end portion of the knob 40B.

  Further, the guide rail portion 24 as shown in FIG. 5 (A) is not formed on the hook 20B, and the guided portion 34 as shown in FIG. 5 (A) is not formed on the adjuster 30. The adjuster 30A is guided on the inner peripheral surface of the knob 40B.

  The present invention includes various other modifications.

  For example, a cushion member such as rubber or sponge is interposed between the bowl-shaped portion 21 and the inner peripheral side edge 2a, between the front end surface 31 and the outer peripheral side edge 2b, or between the convex surface 33 and the front end 41. Also good. In this case, the toilet seat 2 having a slightly different shape can be clamped more closely to make the clamp more firm, and the bolt can be prevented from loosening due to vibration.

  The shape of the toilet seat varies depending on the presence or absence of the heater, the manufacturer, and the model. In accordance with this, a plurality of hooks 20 having different shapes of the base portion 23 or the bowl-shaped portion 21 are prepared, and the user can select an appropriate shape. Of course, the shape of the hook 20 may be selected.

  Furthermore, the clamping attachment type protruding tool of the present invention can be used as a handle for clamping an attached body other than the toilet seat, a locking tool such as a shelf board, an engagement tool or a bracket. In this case, a hollow body having an outer shape corresponding to the application, for example, a cylindrical object can be used.

It is a perspective view which shows the handle attached to the toilet seat of Example 1 of this invention with a part of toilet seat. It is a disassembled perspective view of the handle of FIG. (A)-(D) are the top views of the handle of FIG. 1, respectively, the longitudinal cross-sectional view along the BB line in (A), the right side view of this handle, and the left side view. It is a perspective view which shows the western-style toilet with the handle of FIG. 1 attached.
