  As a puller attached to a fixed portion such as a door or a drawer and used, an embedded type puller in which the puller is embedded in the fixed portion, a pair of mounting legs in the fixed portion, and a handle portion connecting both mounting legs There is known a protruding puller (e.g., Japanese Utility Model Laid-Open Publication No. 63-5161).

  Among them, the projecting puller protrudes from the fixed portion, and when the puller holds the puller, for example, it may overwhelm other fixed portions such as a nearby wall. In particular, in recent years, in order to impart a high-class feeling, metal pull bodies are often used, and in this case, the problem of damage to other members is particularly noticeable. In addition, elderly people whose movements and reactions have become sluggish have unintended contact with pullers in everyday life and are the source of injuries. Also, although it is possible to attach a cushion material (cover member) or the like with an adhesive or the like in order to prevent such a situation, adhesion with the adhesive is due to deterioration of the adhesive due to aging or contact Also has the problem of being easy to peel off.

  In order to solve this problem, according to JP-A-2014-152568, there is provided a pull handle main body having a protruding handle in the front and a front face of the pull main body attached to a fixed part such as a door or drawer. There is disclosed a pull which is composed of a cushion material of a two-layer structure of an inner layer fixed by fitting and an outer layer made of resin, the outer layer of the cushion material projecting from the front surface of the pull body. Further, according to JP-A-2015-85092, a projecting puller main body portion attached to a fixing portion such as a door or a drawer and a resin cover fixed by being fitted on a front surface of the puller main body portion. It consists of a member, and it forms in the central part of the longitudinal direction of the cover member a notch or a cavity giving cushioning property, and a part of the cover member protrudes from the front face of the puller main body. A puller is disclosed. The pullers disclosed in JP-A-2014-152568 and JP-A-2015-85092 each have an arch shape protruding forward, and the cover member protruding from the pull main body portion serves as a cushion to solve the above problem.

  On the other hand, a handle with a square protruding shape in front of (in front of) the linear grip is easy to grip and is preferred. When the puller is pulled out vigorously and collides with another fixed portion such as a nearby wall, for example, the entire front face of the cushion body of the pull portion of the puller strikes the wall or the like. Further, depending on the shape and the position of the other member that collides with, any portion of the grip portion receives the action force.

  Then, when a force applied from the front is repeatedly applied to a puller with a square protrusion in front of (in front of) a member to which the hollow described in JP-A-2015-85092 is applied, a thin portion forming the hollow portion There is a problem that a bending force acts repeatedly at a certain place and a crack is generated at the place.

  Therefore, an object of the present invention is to provide a puller in which the entire porous body constituting the cushion portion is deformed and the bending force is not concentrated at a certain position even if a strong force repeatedly acts on the puller from the front repeatedly. It is to do.

  In such a situation, as a result of intensive investigations, the inventor of the present invention has found that if a resin cover member having a flexible porous body with a specific shape for imparting cushioning properties is inserted into the pull main body, Even if the force is repeatedly applied from the front, the deformation of the porous body is not in the specific direction, and it is freely deformed, and it is found that the bending force is not concentrated on a certain place, etc., and the present invention is completed. The

  That is, according to the present invention, it is fixed by fitting into the puller main body having a square protrusion in the front side attached to the fixed part such as the door or the drawer and the front groove of the pull main body, The cover member is a cover member main body having a shape corresponding to the puller main body, a grip portion of the cover member main body, and the front groove. The cushion portion is formed of a cushion portion formed on the groove bottom side, and the cushion portion is a porous body in which a large number of single-hole bodies are continuous side by side, and the single-hole body extends obliquely inward and downward from the cover member main portion It is an object of the present invention to provide a pull hand characterized in that it is a flexible thin-walled member in which left and right band parts and a tip part of the left and right band parts are connected and a bottom band part protruding on the opposite tip side.

  Further, the present invention provides the above-mentioned pull hand characterized in that the bottom band part connects the tips of the left and right band parts and has an arch-like protrusion on the opposite tip side.

  Further, the present invention provides the pull hand characterized in that the single hole body is flat.

  Further, the present invention provides the pull hand characterized in that the porous body of the cushion portion is a single layer.

  Further, the present invention is to provide the pull hand characterized in that the cushion portion is such that a large number of two or more and 18 or less single-hole bodies are continuous in a row.

  Further, in the present invention, the cover member main body has a two-layer structure of an inner layer and an outer layer, and the resin of the outer layer is a resin softer than the resin of the inner layer. is there.

  Further, according to the present invention, the pull handle main body portion is provided with the pull handle characterized in that both side end portions in the shape of a square protrusion are attachment end faces.

  Further, the present invention provides the above-mentioned pull hand characterized in that both ends of the inner layer of the cover member are provided with locking portions which are bent and extended inward.

  A puller according to a first embodiment of the present invention will be described with reference to FIGS. The pull 10 is attached to a fixed portion 50 such as a door or a drawer by a screw 40. As a door, a pulling door, a raising door, a revolving door, etc. are mentioned. Among these, the revolving door exhibits the effects of the present invention remarkably. Moreover, as a drawer, the thing of various forms, such as what is pulled out to the front, is mentioned.

  The pull 10 has a protruding pull body 1 on the front side. The puller main body portion 1 is a square protrusion in the front side, and a grip portion extending in a straight line parallel to the surface of a door or the like, and both legs extending at a right angle from both ends of the grip portion to the surface side of the door or the like It consists of a department. Thus, a gap 3 is formed between the pull main body 1 and the fixing portion 50, and a finger is inserted into the gap 3 so that the pull main body 1 can be gripped. The end portions of both side legs of the pull main body 1 are the attachment end surfaces 15, and the front view is substantially rectangular.

  The puller main body 1 made of metal exhibits the effects of the present invention remarkably. The metal is not particularly limited, and examples thereof include zinc die cast, brass and stainless steel, etc. or surface finish thereof. The metal also includes, for example, a plating such as a plastic plated on the surface with chromium. By making the puller main body 1 of metal, it is easy to use and can be used stably for a long time.

A hollow groove 14 is formed on the front surface of the pull main body 1. That is, the hollow groove 14 is a groove having a predetermined width w ₂ from one end to the other end, and a predetermined depth h in plan view as shown in FIGS. 9 and 10. Therefore, the upper and lower portions forming the hollow groove 14 are the upper wall portion 11 a and the lower wall portion 11 b which form the upper and lower portions of the pull main body portion 1. Further, screw holes 12 are formed in both leg portions of the hollow groove 14. The lower end 142 of the screw hole having the screw hole 12 is located on the tip end side of the lower end of the leg, and the locking portion 221 of the cover member 2 is engaged therewith. Thus, when the cover member 2 is inserted, the end surface of the cover member 2 is engaged with the lower end 142 of the screw portion and is flush with the mounting end surface 15 of the pull main body portion 1. It will never be. On the other hand, since the front surface of the puller main body portion 1 has a projecting tooth on a part (front side) of the cover member 2, it does not get damaged even if it collides with other fittings etc. is there. The ratio w ₂ / w ₁ of the hollow groove width w ₂ to the thickness w ₁ of the pull main body 1 is approximately 0.5 to 0.7, preferably 0.6.

  Further, the screw hole 12 is screwed with the screw hole 12 by advancing the screw 40 forward from the back side of the fixing portion 50, and the fixing portion 50 and the pull main body portion 1 are fixed. The screw length may be such a length that the screw tip contacts or does not contact the cover member 2.

  The pull 10 includes a resin cover member 2 fixed by being fitted on the front surface of the pull body 1, preferably on the entire front surface. That is, the front surface of the pull main body 1 refers to the grip and the side legs except for the end. The cover member 2 has a cover member main body 24 having a shape corresponding to the puller main body 1, and a cushion 25 which is a grip of the cover member main body 24 and formed on the groove bottom side of the front groove. That is, the cover member 2 is fitted into the hollow groove 14, and a part of the cover member main body portion 24 protrudes from the front surface of the puller main body portion 1 as a projecting tooth. That is, the cover member 2 is to be exposed at all of the front end of the portion projecting from the fixing portion 50. In this way, personal contact does not cause injury. The length of the protruding teeth of the cover member 2 protruding from the front surface of the pull main body 1 is about 2 mm. Further, the lower end of the cushion portion 25 of the cover member 2 is in contact with the bottom of the hollow groove 14. Thereby, even if an object hits the protrusive tooth portion, the cushion portion 25 is deformed to exhibit cushioning properties. Further, screw holes through which screws pass are formed in the locking portions 221 which are both leg portions of the cover member 2.

  The cushion portion 25 is a porous body in which a large number of single-hole members 26 continue in a row, and the single-hole members 26 are left and right band portions 261 and 261 extending diagonally inward and downward from the cover member main portion 24; A flexible thin-walled member is formed by connecting the tips of the H.261 and forming an arch-shaped bottom band portion 262 on the opposite tip side. That is, the plan view shape of the single-hole body 26 is substantially W-shaped, and the inverted V-shape at the center of the W-shape is substantially inverted U-shaped. The reason why “substantially” is used as the substantially inverted U-shape is that the height is lower than the U-shape. That is, the height of the central arch may be approximately 1 mm. That is, it is preferable that the “hole” of the single-hole body 26 is a through hole, and the single-hole body 26 has a flat shape. In addition, the porous body of the cushion portion 25 may be a single layer, and it is preferable that the cushion portion 25 be one in which a large number of two or more and 18 or less single porous bodies continue in a row. That is, in the porous body, flat through holes are continuous side by side. Thereby, the cushioning property can be enhanced while maintaining the strength. The cushion portion 25 is preferably made of a soft resin described later. Further, the band widths of the left and right band portions 261 and 261 and the bottom band portion 262 are the same as the width of the cover member main body portion 24 and are almost the same as the groove width of the hollow groove 14. In addition, the thickness (thin wall) of the left and right bands 261 and 261 and the bottom band 262 may be about 1 mm. The flexibility means that the cushion portion 25 is deformed when the cover member main body portion 24 and the cushion portion 25 are pinched with a finger.

  The cushioning action of the cushioning portion 25 will be described with reference to FIG. FIG. 14A shows a cover member before an external force acts, and FIG. 14B shows a cover member after an external force acts and the cushion portion 25 is crushed. In the pull 10, when the external force P acts uniformly on the raised teeth of the grip portion of the cover member main body 24, the cushion 25 is pushed from both the cover member main body 24 and the groove bottom of the pull main body 1, It deform | transforms like (B) of FIG. At this time, since the left and right band portions 261, 261 of the single hole body 26 of the cushion portion 25 extend obliquely downward and inward from the cover member main body portion 24, the external force P is perpendicular or oblique to the cover member 2. Even if it works, the shape of the single-hole body 26 is deformed so as to be crushed. That is, the left and right band portions 261, 261 further bend inward to push the bottom band portion 262 toward the cover member 2 side. Originally, the bottom band portion 262 protrudes to the side of the cover member 2 and always deforms to the tip side (upper side in FIG. 14) against external force. Then, the bottom band portion 262 abuts on the back surface of the cover member 2 when it is further strongly pressed. Under the present circumstances, in the single hole body 26, since the contact points 263 and 264 which contact at two places of the groove bottom and the contact point 265 which contacts at the back of the cover member 2 both become round shape, acute bending places Does not occur. As described above, even if a force is repeatedly applied to the pull 10 from the front, the single-hole body 26 and the porous body 25 which is a continuous body of the single-hole body 26 are deformed such that the bending force is not concentrated at a certain place. . Therefore, during long-term use, there is no looseness or damage of the cushion portion, and can be used safely for a long time.

  On the other hand, for example, the cushioning action of the cover member of the conventional example shown in FIG. 19 will be described. In the cover member 200 of FIG. 19, a rectangular through hole 201 is continuous in the longitudinal direction. That is, when an external force acts on the cover member 200, the through hole 201 is crushed and deformed to exhibit cushioning properties. In the cover member 200, the adjacent through holes 201 are partitioned by a plate-like wall 202 extending in a direction orthogonal to the longitudinal direction of the cover member body. For this reason, when the external force P acts on the cover member 200, the plate-like wall 202 always bends so as to fall down to either one, and the through hole 201 is crushed. In this case, the deformation of the cover member 200 may move largely in the longitudinal direction, and the locking of the leg may be released.

  The resin of the cover member 2 preferably has a flexural modulus of 1.8 GPa or more, preferably 2.0 GPa or more, from the viewpoint that a strong spring force is obtained and sufficient fitting strength can be obtained. Examples of the resin include acrylonitrile butadiene styrene (ABS) resin, polyacetal and nylon, and specific examples thereof include Duracon "M90-44"; flexural modulus of 2.6 GPa (manufactured by Polyplastics), Iupital " F20 ": flexural modulus 2.6 GPa (Mitsubishi Engineering Plastics Co., Ltd.), tanazine" TN 500 "; flexural modulus 2.5 GPa (made by Takayasu Co., Ltd.), tanazine" TN 710 "; flexural modulus 2.9 GPa (made by Takayasu Co.) Can be mentioned.

  As shown in FIGS. 11 and 12, the cover member 2 has a shape similar to that of the pull main body 1 as a whole, and both end portions are locking portions 221 extending inward. As a result, it is locked to the locking portion 142 of the pull main body 1 and fixed by the screw 40. Further, the cover member 2 is an elastic body, and by spreading the both sides against the spring force, the space between the locking portions 221 at both ends is expanded. That is, by pushing the cover member 2 into the hollow groove 14 of the puller main body 1 strongly by hand, the distance between the initial locking portions 221 is increased, and after fitting, the two are integrated by restoration. It will be done. That is, the elasticity of the cover member 2 is such elasticity that it is finally deformed by the strong force of the hand. Thereby, it does not remove easily after fitting.

  The cover member main body portion 24 and the cushion member 25 may be integrally molded, or both may be separate members, and the cover member main body portion 24 and the cushion member may be attached with an adhesive or a double-sided tape. Among these, one in which the cover member main body portion 24 and the cushion member 25 are integrally molded is preferable.

  Next, a method of assembling the pull 10 will be described with reference to FIGS. 12 and 13. 12 and 13, in order to make it easy to understand the engaged state of the pull main body 1 and the cover member 2, the pull main body 1 is shown in a cross section as shown in FIG. First, the cover member 2 having the pair of locking portions 221 from the front side of the pull main body 1 facing the pull main body 1 is fitted into the hollow groove 14. Under the present circumstances, since the distance between a pair of latching | locking parts 221 is smaller than the maximum length of the hollow-shaped groove 14, in the middle of fitting the cover member 2 in the hollow-shaped groove 14, as shown in FIG. The tip end of the locking portion 221 abuts on the groove bottom surface 141 in the vicinity of both ends of the hollow groove 14. From this state, the cover member 2 is strongly pressed to the puller main body 1 side against the spring force and fitted. As a result, the distance between the initial locking portions 221 is increased, and after the cover member 2 is fitted in the hollow groove 14, the two are strongly fitted and integrated by restoring (FIG. 13). . Further, the lower end of the cushion portion 25 of the cover member 2 is in contact with the bottom of the hollow groove 14. Thereby, even if an object hits the cover part main body part 24 of a convex tooth, the cushion part 25 deforms and exhibits cushioning properties.

  As shown in FIG. 15, the cover main body 24 may have a two-layer structure of an inner layer 22 and an outer layer 21 made of resin. As a form of fitting of the inner layer 22 and the outer layer 21 in the two-layer structure, for example, a form as shown in FIG. 16 may be mentioned. That is, the inner layer 22 is composed of the base 223 and the projection 224 projecting upward from the center of the base 223 in the form of a hook, and the outer layer 21 is concave with the shape of the projection 224 of the inner layer 22 cut out. Thereby, the fitting strength of the inner layer 22 and the outer layer 21 is improved.

  In the cover member 2b, the inner layer 22 is preferably a hard resin or metal, and the outer layer 21 is preferably a resin softer than the hard resin (hereinafter, also referred to as "soft resin"). Particularly preferably, the inner layer 22 is a hard resin and the outer layer 21 is a soft resin It is. By this, it is possible to firmly fit on the fixed side, and the cushioning property is enhanced on the protruding side. Moreover, although the cushion part 25 is formed inside the inner layer in a holding part, the integral one with the outer layer 21 may be sufficient. This is because the cushion 25 is made of soft resin. As the hard resin, those similar to the resin of the cover member 2 can be used. Further, as the soft resin, silicone resin (SI), polyurethane resin (PUR), vinyl chloride resin (PVC), ethylene vinyl acetate copolymer resin (EVA), EEA resin (EEA), thermoplastic polyurethane elastomer (TPU), Thermoplastic elastomers (TPE) can be mentioned. The hardness of the soft resin is 40 to 90, preferably 50 to 80 in Shore hardness. The adhesion of the hard resin 22 and the soft resin 21 can be integrated by molding the resins. It is preferable to use an ABS resin as the hard resin and a soft elastomer as the soft resin in terms of improving the adhesion between the resins by molding. The thickness of the inner layer 22 can be thinner than the outer layer 21 because a hard resin is used. That is, the thickness of the inner layer 22 may be 1/6 to 1/2 of that of the outer layer 21.

  Similar to the cover member 2, the cover member 2b is entirely shaped similar to the shape of the pull main body 1, and both ends are locking portions 221 extending inward (FIG. 15). The hard resin, which is the inner layer, is bent from the grip portion and extends to the middle of the leg portion to form a locking claw 219. As a result, the locking portion 143 on the tip end side of the pull main body portion 1 can be strongly locked. On the other hand, the soft resin 21 is laminated on the outer periphery of the hard resin 22. Thereby, the end faces of the hard resin 22 and the soft resin 21 become flush, and the outside becomes the soft resin. In addition, the cover member 2b has an effect of attachment similar to the cover member 2 (FIG. 15).

  In the present invention, the cushion portion 25 can take various modifications. That is, the left and right band portions constituting the single hole body are not limited to those extending in an oblique straight line as shown in FIG. 13, but may be arc-shaped as shown in FIG. Further, the bottom band portion constituting the single-hole body is not limited to an arch-like protrusion on the opposite end side as shown in FIG. 13, but as shown in FIG. It may be. Further, the left and right bands constituting the single-hole body are not limited to those extending directly from the cover member main body as shown in FIG. 13, but slightly (within 1 mm) from the cover member main body to the tip side. It may be via a hanging member. In this case, the left and right bands extend obliquely from the tip end of the hanging member. Such a form is the same shape as the single-hole body in the case where there is no inner layer 22 constituting two layers in FIG. Moreover, what protrudes from the front surface of the pull main body part 1 may not only be a part of outer layer, but the whole outer layer may protrude.

  According to the puller 10 of the present invention, for example, when the puller of the rotating door is pulled toward the front, the cover member 2 of the puller 10 hits even if it collides with other adjacent fixtures due to excess force. The action of relieving collisions does not damage other fixtures. In addition, even if the puller 10 touches the hands and feet of the elderly, the cover member will hit, so the elderly will not be injured. Further, even if a force is repeatedly applied to the puller from the front, the deformation of the single hole body is not in the specific direction, and the collapsing part is also deformed roundly so that the bending force is not concentrated at a certain place. Therefore, during long-term use, there is no looseness or damage of the cushion portion, and can be used safely for a long time.
