Description

  The present invention relates to a mail box, and more particularly to a mail box having a mail theft prevention function and a slot opening / closing control means. When it is necessary to refuse the insertion of flyer advertisements, etc., it is possible to close the input port of the mailbox for the necessary period, and when the input port is opened, The present invention relates to a multi-function mail box equipped with a flap opening / closing control means capable of preventing theft.

  To receive mail and other deliverables in daily life, not only apartment houses and apartment houses such as apartments and apartments, office buildings, etc., mail boxes are also widely used in ordinary houses. Yes.

  Various types of conventional mailboxes are used, but the basic configuration is a box-shaped mailbox box body and a mail piece formed on the front plate of the mailbox box body. It is comprised from the insertion port for injection | throwing-in, the storage room which accommodates the mails etc. which were thrown in from the said insertion port, and the exit for taking out mails. Such mailboxes usually have a front-entry / front-out type in which the outlet is provided at the lower part of the insertion port on the front side of the mailbox, or a front-in / out-out type with an open / close door on the back side. is there.

  By the way, in recent years, mail boxes and newspapers as well as a large number of throwing flyer advertisements have been put into postal boxes of unoccupied houses such as houses and apartments that have been away for a long time. In particular, apartment buildings are easy to be targeted, and as a result, flyer advertisements overflow from the mailbox and are scattered to the surroundings, which not only significantly impairs the aesthetics but also may cause fire and arson. In addition, the absence of residents is clear from the state in which leaflet advertisements overflow from the mailbox, which may be a hotbed of crime.

  On the other hand, in recent mailboxes, in order to cope with an increase in the volume and size of deliverables such as mail, the size of the input port has been increased. Therefore, in such a mailbox, even if the door is equipped with a locking device such as a dial lock, it is possible to easily steal delivery items inserted into the mailbox by inserting a hand through the slot. In fact, theft has been pointed out.

  Therefore, in the absence of a long period of time, the input port flap can be locked and the input port can be closed, and when the input port is opened, a multifunctional mailbox can be developed with a function capable of preventing theft of deliveries. It has been longing for.

  Under such circumstances, formulating preventive measures to prevent unauthorized entry of flyer advertisements, etc. has been studied, but in addition to the above circumstances, it is an important and urgent problem in managing apartment buildings. There have been proposed various entry refusal tools for preventing the insertion of flyer advertisements, etc. in mailboxes such as unoccupied houses and long-term absent houses.

  For example, as an input rejection tool, Japanese Patent Laid-Open No. 2000-232933 (hereinafter referred to as “Patent Document 1”) has a horizontally long rectangular input port as an instrument for rejecting input into an existing mailbox. The lower end of the insertion port is attached to a mailbox having a cross-sectional structure of an insertion port that is bent at a predetermined depth and has a size that covers the insertion port. A structure is described in which the inlet opening lower edge latching structure is located at the lower edge portion.

  However, the insertion refusal tool described in Patent Document 1 has a structure that can only be attached to a postbox having a cross-sectional structure of an insertion port in which the lower edge of the insertion port is bent at a right angle as described above. Therefore, there is a problem that it is not possible to cope with various types of mailboxes that have been diversified in recent years.

  Although it is stated that such a loading refusal tool can be detachably attached, it requires a lower edge latching structure in the loading slot for latching on the lower edge of the loading slot, and also requires two types of folding claws. The structure is complicated.

  Japanese Patent Application Laid-Open No. 2003-93215 (hereinafter referred to as “Patent Document 2”) describes a flat front cover member having a size that can close the input port in a state where it cannot be input, and an input port. A flat plate-like back support member that has an engaging portion that can pass through and can contact the back portion of the lower edge of the input port, and the front covering member and the back support member are communicated so that the facing interval and the facing angle can be changed. There is described a throw-in refusal tool that includes a bolt and a nut, and is provided with a spacing holding means for preventing the close contact between the front covering member and the back support member at a position facing the engaging portion of the back support member.

  However, the insertion refusal tool described in Patent Document 2 is also complicated in structure, and requires a long time for attachment work, and has a problem that it is difficult to attach easily.

  Furthermore, Utility Model Registration No. 3093560 (hereinafter referred to as “Patent Document 3”) describes a dosing prevention device that is made of a sheet made of polypropylene resin or the like and is assembled by being bent into a predetermined form. It is described that the folding sheet is inserted by inserting the insertion portion of the folded sheet from the insertion port.

  However, the insertion refusal tool described in Patent Document 3 uses a material made of synthetic resin, which is problematic in terms of strength and may be destroyed. Has been.

  On the other hand, as a mail box with an anti-theft function, for example, Japanese Patent Laid-Open No. 2001-29214 (hereinafter referred to as “Patent Document 4”) discloses a large-sized delivery opening that is opened at the top front of the mail box. An anti-theft plate that prevents the insertion of a hand from the slot is provided inside, and a slit is opened below the slot to allow a thin delivery of postcards or sealed letters to be inserted independently of the slot at the top of the front The mail box is listed.

  Japanese Patent Laid-Open No. 2006-218004 (hereinafter referred to as “Patent Document 5”) discloses an inner lower portion of a loading lid pivotally pivoted inside an upper frame that forms a loading port of a front portion of a mailbox. By screwing the screw into the screw and adjusting the length of the screw's protruding dimension, when the input lid is opened, the opening degree of the input lid when the screw contacts the top plate of the mailbox can be regulated, It describes a mailbox that cannot be easily inserted by a person through the slot.

  However, the insertion refusal tools described in Patent Documents 1 to 3 are all applied to the existing mailbox, as described above, and the structure is complicated, and the installation work is complicated. There is a problem that it cannot be mounted by a simple operation.

  In addition, the mailbox described in Patent Document 4 requires that large delivery items and small delivery items be entered separately, so that the work is complicated, and it corresponds to the rejection of insertion of flyers and the like as described above. Can not. In the mail box described in Patent Document 5, when there is only one screw to be screwed into the charging lid, there is a risk that the charging lid may be deformed only by applying a slight force. In order to adjust the protruding dimension of a screw with a screwdriver or the like, it is not easy to make the protruding dimensions of a plurality of screws the same, and it is impossible to prevent theft by simple operation. Moreover, it cannot respond to the rejection of the above-mentioned flyer or the like.

  As described above, the mailboxes described in Patent Documents 1 to 5 have problems as described above, and each mailbox has both a function for preventing the insertion of leaflets and the like and a function for preventing theft. It is not prepared.

Therefore, a mail box with a simple structure, in which, when the slot is closed, the slot flap is fixed at the closed position, and when the slot is opened, the slot flap opening / closing control means can exhibit the anti-theft function. Development has been eagerly desired.
JP 2000-232933 A JP 2003-93215 A Utility Model Registration No. 3093560 JP 2001-29214 A JP 2006-218004 A

  Accordingly, the problem of the present invention is that it is possible to close the insertion slot in order to refuse the insertion of leaflets, etc. into a mail box such as a home away from home for a long period of time, and at home. An object of the present invention is to provide a postal box with multiple functions, such as being able to prevent the theft of postal items and other delivered items when the input port is opened.

  Therefore, as a result of intensive studies in order to solve the above-described problems of the present invention, the inventors have been able to fix the free end of the inlet flap in the closed position, and when the inlet is opened. In that, focusing on the fact that the above problem can be solved by providing a mail box with a flap opening and closing control means comprising a slide plate member having an inverted L-shaped cross-section capable of preventing theft of stored mail items, The present invention has been conceived based on such knowledge.

  In other words, according to the present invention, the inlet flap opening / closing control means comprising the support member fixed to the lower edge of the inlet and the slide plate member, which is slidable in the vertical direction, and has the inlet flap. A slide plate member with a slide groove that can be held at any position to open and close the slide plate. The slide plate member has an inverted L-shaped longitudinal section, and the inner angle of the inverted L-shaped is specified. It is intended to provide a mailbox with the input port flap opening / closing control means.

  In the present specification, the “closed position” is a position where the free end of the inlet flap comes into contact with the inlet edge.

Thus, according to the present invention,
1. The mailbox,
A slot formed on the front surface of the mailbox box body;
An inlet flap having a base end pivoted inwardly at the upper edge of the inlet;
A mailbox with a doorway,
A support member fixed to the lower edge of the inlet, and a slide plate member that is supported by the support member so as to be movable up and down, and can be fixedly held at an arbitrary height position, and has an inverted L-shaped cross section. There is provided a mail receiving box characterized in that it is provided with an input port flap opening / closing means capable of controlling the opening and closing of the free end portion of the input port flap.

  Furthermore, the following 2-6 are included as preferable embodiment of this invention.

  2. The inverted L-shaped slide plate member is composed of a lateral flange portion and a vertical plate portion, and the inner angle between the flange portion and the plate portion is opened and closed at the free end portion of the inlet flap. The mailbox according to the above 1 is provided at an angle set so as not to come into contact.

  3. The mailbox according to 1 above, wherein the inverted L-shaped slide plate member is an integrally formed body of a collar portion and a plate portion.

  4). The support mechanism of the slide plate member by the support member is an inverted L-shape in which an inverted T-shaped slide groove or an L-shaped slide groove into which the support member and the rod-like body portion of the support member are inserted is formed. 2. The slide plate member according to 1 above, wherein the rod-shaped body portion of the support member is slidable in the slide groove and has a sliding structure that can be fixedly held at an arbitrary height position. A mailbox is provided.

  5. The mailbox according to 1 above, wherein an inner angle between the flange portion and the plate portion of the inverted L-shaped slide plate member is 90 degrees or more.

  6). 2. The mailbox according to 1 above, wherein the support member is a bolt and a nut fixed to the lower edge of the insertion port.

  7). 2. The mailbox according to claim 1, wherein the opening degree adjusting means of the insertion port flap is a leg member whose length can be adjusted fixed to the back side of the free end portion thereof.

  The mail receiving box according to the present invention is fixed in a closed position for closing the input port when a flap pivotably openable at the input port is required, and when the input port is opened, Other components are not particularly limited as long as they have a structure equipped with a mail theft prevention means and have such a multi-function.

  As described above, the mailbox according to the present invention includes a multifunctional mailbox that includes a function for rejecting insertion of leaflets, etc. in the absence, and a function for preventing theft of postal items when the slot is opened. It is a new one that is not disclosed.

  The mail box according to the present invention has at least the following two features.

  That is, the first point lies in that an inlet flap opening / closing control means capable of arbitrarily closing the inlet is provided to break the conventional common sense of a mailbox.

  The mailbox is originally a tool for receiving delivery items such as mail, and it has been considered that its function cannot be exerted unless the slot can be kept open at all times. Therefore, from this point of view, there has been no idea that a closing means is provided at the input port, and there is no postbox provided with the closing means at the input port. Under such circumstances, the present inventors have proposed for the first time, and provide a new mail box by changing the way of thinking.

  The second point is that the anti-theft function of postal items accommodated from the slot when the slot flap is opened can be exhibited.

  Conventionally, as a means for rejecting the insertion of leaflets or the like, a shielding plate or the like that is inserted into the input port by removing the input port flap has been proposed. According to this proposal, the input port is in a completely open state or only has an alternative function of a completely closed state. Although the delivery port can be thrown in by adopting the loading port flap opening / closing means having a function, it is configured to prevent theft such as taking out the delivery item from the loading port. Such an inlet flap opening / closing means is, of course, new in combination with the new existence of the closing function of the inlet, and has a simple structure and has a remarkable effect.

Mailbox main body The mailbox main body of the mailbox according to the present invention has a box structure. A storage room for storage and an outlet for taking out a delivery stored in the storage room are provided in the lower part of the front part, the back part, the side part or the like.

  There are two types of mailboxes: the front-in / out-front type with an open / close door on the front part located at the bottom of the slot and the “front-in / post-out” type with an open / close door on the back. Structure.

  The front-entry / post-type mailbox is closed at the back and is provided with an open / close door at the front located below the slot.

  On the other hand, a front-in / post-out type mail box has a front part closed at the lower part of the insertion slot, and an open / close door provided on the rear part.

  There is no limitation on the internal structure of the mailbox, but it is preferable to provide an inclination toward the take-out port so that delivery can be taken out easily.

  In addition, when operating the insertion opening flap opening / closing means, in the case of a front-in / out-door type mail box, the front opening / closing door is opened and the support member fixing means is rotated by a finger so that the slide plate member The position may be adjusted. In addition, with regard to a front-in / post-out type mail box, the position of the slide plate member of the inlet flap opening / closing means may be adjusted by opening the rear opening / closing door and inserting a hand from the rear surface.

  Although there is no limitation in the material of a mail box main body, stainless steel is preferable and stainless steel or aluminum die-casting etc. are preferable also about an opening / closing door.

  According to the present invention, a box having a shallow bottom, a so-called low height, and a relatively large input port, which is usually a box with a size that allows easy insertion of a hand and allows a finger to reach the bottom surface. In the post box consisting of the body, a remarkable anti-theft effect is achieved due to the fact that hand insertion can be prevented. In particular, a remarkable effect can be exerted as described later in a shallow mailbox with a box height of 150 mm or less.

Input flap The input flap as a component of the mail box according to the present invention is an opening / closing cover plate provided to close the input port for mail or the like or to form a predetermined gap. It is a base end portion pivotally fixed to a pivot shaft attached to the upper edge portion of the insertion port, and is pivotally fixed. A lower end portion of the base end portion is a free end portion. The flap normally has its free end in contact with the lower edge of the closing port at the closed position due to its own weight, and the loading port is in a state in which mail or the like can be loaded by pressing the flap.

  Therefore, when throwing mail or the like into the mailbox, after the flap is pushed open and the mail or the like is thrown into the mailbox, the flap returns to its original closed position by its own weight.

  In addition to the form pivoted on the horizontal pivot shaft, the inlet flap is rotatable about a vertical shaft provided at the inner wall inlet located on either side of the inlet. Even if it is in the form of a pivoted lateral opening, it can be fixed in the closed position if its free end is incorporated as one element of the inlet flap opening / closing means according to the present invention.

  Furthermore, the post opening box flap according to the present invention can be provided with an opening degree control means as previously proposed by Japanese Patent Application No. 2013-186676. As a means for controlling the opening degree of the inlet flap, in addition to the above proposal, a leg member having an adjustable length dimension can be used which is detachably fixed to the inner tip of the free end of the inlet flap. Specifically, as the leg member, it is possible to arbitrarily select a protrusion-shaped object whose length dimension can be adjusted, a screw screwed into a screw hole formed in the free end portion of the insertion port flap, and the like. When the dimension of the leg member is increased, the contact of the free end portion of the insertion port flap with the upper inner wall of the mail box main body can be suppressed, and the opening degree of the insertion port flap can be reduced. By arbitrarily reducing the opening degree of the inlet flap, as will be described later, it is possible to achieve a synergistic effect with the inclination effect of the flange portion of the inverted L-shaped slide plate member according to the present invention.

Input Port Flap Open / Close Control Unit The input port flap open / close control unit of the mail box according to the present invention has a function of preventing theft of the stored delivery items.

  The opening / closing control means for opening / closing flaps of the mailbox according to the present invention closes the insertion slot when it is necessary to refuse the insertion of leaflets, etc. when there is no long-term absence, and accepts delivery of postal items after the period has elapsed In addition, it is possible to release the closing of the insertion slot, prevent the mail from being stolen from the insertion slot, etc., and have a multi-function effective for achieving other purposes.

  The opening flap opening / closing control means as a component of the mailbox according to the present invention is a closed position in which the free end of the insertion opening flap pivotally pivoted inward is in contact with the opening opening edge. In addition, when the insertion port flap is opened, it has a mail theft prevention function, and has both the opening / closing function of the insertion port flap and the antitheft function.

  Such an inlet flap opening / closing control means is supported by a support member fixed to the lower edge of the inlet, and is supported by the support member so as to be movable up and down, and can be fixedly held at an arbitrary height position, and the cross section is reversed. It is composed of an L-shaped slide plate member.

  One of the supporting members is a rod-like body portion fixed to the inside of the lower edge of the inlet, and the other end is inserted into a slide groove formed in the plate portion of the slide plate member having an inverted L-shaped cross section. The vertical position of the inverted L-shaped slide plate member is fixedly held.

  Specific examples of the support member include a bolt that can be screwed with a nut, a rod-like body or a screw having a spiral groove formed at the tip, and the like. The fixing to the inner side of the lower edge of the inlet may be performed by forming a screw hole in the lower edge of the inlet and screwing the bolt or the like, but the screw hole may be screwed into the screw hole. Good. The fixing structure is not particularly limited as long as it is a support member having a structure that allows the inverted L-shaped slide plate member to be vertically moved. After the base end is screwed, the bolt is inserted into the inverted T-shaped slide groove or L-shaped slide groove of the inverted L-shaped slide plate member, and then the bolt end is screwed with the nut to reverse L A letter-shaped slide member can be communicated. As the fixing structure, there are various types as described above, but a structure in which a bolt or a rod-shaped body having a spiral end structure is screwed with a nut or a fixing structure having a screw as an element as shown in the drawing is preferable. The second component of the input port flap opening / closing control means of the mailbox according to the present invention is a reverse L-shaped slide plate member (hereinafter, sometimes simply referred to as “reverse L-shaped slide plate member”). is there.

  The inverted L-shaped slide plate member is composed of a lateral collar portion and a longitudinal plate portion as shown in the drawings described later.

  The flange portion and the plate portion may be made of the same material or different materials. A structure formed by connecting the longitudinal surfaces of independent members, or the flange portion and the plate portion made of the same material. Although an integrally formed body can be mentioned, an integrated formed body of a collar part and a plate part made of the same material is simple and easy to manufacture and use as an inverted L-shaped slide plate member. Is particularly preferred.

  In such an inverted L-shaped slide plate member, the inner angle (α) at the connection surface between the flange portion and the plate member (in the specification according to the present invention, α shown in FIG. 6 is referred to as “inner angle”). In order to prevent theft, it is preferable that the angle is set to a maximum angle so as not to come into contact with the free end when opening the insertion port flap for inserting mail or the like. . On the other hand, there is no particular limitation because it is necessary to insert mail items without any problem. Specifically, the height of the box is 150 mm or less, and the width of the slot (vertical width) ) Is 30 mm or more, and the inner angle (α) of the inverted L-shaped slide plate member can be selected in the range of 90 to 120 degrees when the height position of the lower edge of the inlet is 100 mm or less.

  If the internal angle (α) of the inverted L-shaped slide plate member is 90 degrees or less, it is easy to put a hand inside the mailbox, while if it is 120 degrees or more, it is difficult to insert mail. May arise.

  In addition, the length of the collar portion of the inverted L-shaped slide plate member (the lateral direction of the inverted L-shaped slide plate member) is the size and height (that is, the depth) of the box of the mailbox, and the width of the insertion slot. It is determined by the height (vertical width) and the height position. In particular, it is necessary to increase the length of the buttocks for a mailbox with a shallow bottom. Usually 30 mm or more is preferable.

  When the heel is short, the hand can be easily inserted, while when the heel is long, for example, when the length exceeds 60 mm, it becomes difficult to insert mail.

  Further, the length of the plate portion in the vertical direction is determined within a range in which the opening / closing control of the inlet flap can be performed by moving up and down.

  The plate portion of the inverted L-shaped slide plate member is provided with an inverted T-shaped slide groove or an L-shaped slide groove for connecting to the support member within the range of the above-described vertically movable width. It is.

  Thus, the support mechanism for the inverted L-shaped slide plate member specifically includes a support member fixed to the lower edge of the inlet at the inverted T-shaped slide groove formed in the inverted L-shaped slide plate member. By inserting the rod-shaped body portion, the inverted L-shaped slide plate member is supported and can be moved up and down by sliding, and the bent portion of the inverted L-shaped slide plate member can be positioned at any height. That is, it becomes possible to fix the closing position height of the insertion port flap. More specifically, the rod-shaped body portion of the support member is inserted into the inverted T-shaped slide groove of the inverted L-shaped slide plate member, and the rod-shaped body portion slides along the inverted T-shaped slide groove, The inverted L-shaped slide plate member is movable in the vertical direction, and the rod-shaped body portion of the support member is moved and fixed to the lateral groove of the inverted T-shaped slide groove, whereby the inverted L-shaped slide plate is The member moves upward and comes into contact with the free end of the inlet flap, thereby closing the inlet flap.

  The movable form of the inverted L-shaped slide plate member shown in the mail box according to the present invention is two forms of the vertical direction and the lateral direction using the inverted T-shaped slide groove, but the form of the slide groove is reversed. Even if it changes to forms other than a T-shape, if opening / closing control of an inlet flap is possible, it can employ | adopt, without specifically limiting. For example, even if the slide groove is L-shaped, the inverted L-shaped slide plate member can be moved vertically and fixedly held in the lateral direction.

  Further, in the inverted T-shaped slide groove or the L-shaped slide groove, a plurality of lateral slide grooves may be added and drilled.

  A specific embodiment of the input port flap opening / closing control means constituting the mailbox according to the present invention is shown in FIG. 3 as a perspective view of the input port flap opening / closing control means when the input port flap is in the closed state. Fig. 7 shows an exploded perspective view, and Fig. 7 shows the positional relationship of each element of the inlet flap opening / closing control means when the inlet flap is in the open state. Further, in FIG. 8, the insertion port flap is in a closed state due to the upward movement of the insertion port flap in the inverted L-shaped slide plate member.

  As described above, the mailbox according to the present invention is supported by the support member fixed to the lower edge of the slot, and is supported by the support member so as to be movable up and down, and can be fixedly held at an arbitrary height position. A post box comprising a slot opening / closing control means capable of controlling the opening and closing of the free end of the slot flap, comprising a slide plate member having an inverted L-shaped cross section, and when using the mailbox In the case of opening and closing the insertion port, the following procedure may be followed and the operation can be performed with one touch.

1. Depending on the type of mailbox, open either the front door or the back or side door.
2. The support member inserted into the slide groove of the reverse L-shaped slide plate member by sliding the reverse L-shaped slide plate member of the inlet flap opening / closing control means installed on the rear surface of the front door in the vertical direction. The position is fixed so as to be a predetermined position of the slide groove. The predetermined position is specified in advance as the opening / closing position of the inlet flap. In the embodiment of the present invention, when closing the inlet flap, the position of the support member is the base end portion 432 of the inverted T-shaped slide groove, whereas when opening the inlet flap, at the distal end 431. is there.
3. Close the door.

  The present invention is configured as described above, and can provide a multi-function mailbox. The inlet flap opening / closing control means has a simple structure, does not cause any problems over a long period of time, and has a long service life. Further, the free end portion of the insertion port flap can be fixed to the closed position and fixed to the open position by a simple operation only by the vertical movement operation of the inverted L-shaped slide plate member and the fixing operation of the support member. In addition to preventing the insertion of leaflets, etc. in the absence of a long period of time, when the insertion opening is opened, the insertion of a human finger is prevented by an inverted L-shaped slide plate member having a collar with an inner angle (α) of 90 degrees or more, Multifunctionality can be exhibited such as theft of postal items can be prevented. Furthermore, the antitheft effect can be further synergistically enhanced by the combined use with the opening degree control of the inlet flap.
