Description

  The present invention relates to a self-supporting signboard.

A stand-type signboard, that is, a self-supporting signboard, is generally installed and used at a storefront on the street or at the entrance of a building for store advertisement or guidance.
This self-supporting signboard is traditionally equipped with an electric cord and receives power supply from a power outlet to a light source that illuminates the advertising surface of the signboard.
However, when a power source is secured from an outlet using an electrical cord, the installation range of the signboard is limited where the electrical cord can reach. There is also a concern that passers-by will get caught in the electric cord.
For this reason, various types have been proposed in which a rechargeable battery is built in a sign and does not require connection of an electric cord when the light source is turned on (Patent Documents 1 to 5).

In the signboards shown in Patent Documents 1 to 5, when the signboard is used, electricity can be supplied from the built-in battery to the light source to light the signboard.
Among these, in the self-supporting signboard shown in Patent Documents 2 to 5, the charger is also built in the signboard, and when not in use, the charger is connected to the outlet in the store with an electric cord to charge the battery. It is.
For this reason, in the self-supporting signboards shown in Patent Documents 2 to 5, it is necessary to move the entire signboard into the store after closing.
On the other hand, in the signboard shown in Patent Document 1 (publication FIGS. 1 to 4), the battery 5 when the signboard is used is accommodated in the signboard, and the battery 5 is removed from the signboard when charging and connected to an outlet. 18 and charged (publication figure 4). That is, in the signboard disclosed in Patent Document 1, only the battery 5 may be carried to a place where the charger 18 is present when charging.

However, even if it can be charged by removing only the battery from the signboard, the battery itself is heavy and inconvenient to handle.
For example, if the battery after being removed from the signboard and charged is pushed into the signboard again, there is a concern that the entire signboard will escape in the direction in which force is applied and the battery cannot be stored smoothly.
This is because the battery is heavy and the frictional resistance between the battery and the base is large. That is, once a battery with a large mass is placed on the upper surface of the base of the signboard, the base is also integrated with the battery by pressing the battery to move it to a predetermined position by shifting the battery on the base. Escape in the pressing direction. Of course, the battery is not directly brought into contact with the upper surface of the base, but the battery is disposed on the leakage prevention case provided at the battery installation position (the leakage prevention case 9 in FIG. 3 of Patent Document 1). It is also conceivable to smooth the battery placement surface in the prevention case. However, although the frictional resistance is slightly reduced, it is not a fundamental improvement for facilitating battery insertion.
In the self-supporting signboard provided with casters that roll on the ground, the above-mentioned escape of the signboard is particularly prominent. Further, the caster generally has a direction of movement that can be freely changed, and the escape direction of the signboard is not determined. Such a caster significantly hinders smooth battery installation.
If the above-mentioned problem of the casters is disliked, when attaching the battery, it is necessary to use a caster ring stopper or to use a stand device that lifts the casters to release the grounding of the casters.

Recently, internally-lit signboards using LEDs (light-emitting diodes) as light sources instead of conventional fluorescent lamps are becoming popular as self-supporting signboards, and the self-supporting signboards are also becoming lighter.
Originally, a battery is heavier than other parts of a signboard, and the above-mentioned tendency to reduce the weight spurs this difference in weight.

Under such circumstances, the inventor of the present invention examined whether or not the rechargeable battery removable from the signboard can be handled smoothly. The focus was on the recent rechargeable battery for electric-assisted bicycles, which are becoming smaller and easier to handle.
The battery of this electric assist bicycle is generally a lithium ion secondary battery, and is designed to be easy to handle in consideration of the fact that there are many women among users of the electric assist bicycle.
That is, a battery of a battery assisted bicycle in recent years is widely used that is attached to the bicycle along the seat pipe of the bicycle. The width in the front-rear direction and the lateral direction in the vertical direction (longitudinal direction) of the seat pipe extend. The vertical width is small. Moreover, the battery of an electrically assisted bicycle is generally provided with an electrical contact at the lower end and a handle (grip) at the upper end. When charging, remove the battery from the bicycle, carry the battery with the handle, connect a charger separate from the bicycle to a household outlet, and connect the battery to the charger to charge it. is there.
In addition, battery stands that can charge batteries for electric assist bicycles are being installed in bicycle dealers and public institutions, and the environment for charging tends to expand.
Therefore, it can be said that the use of the battery for the electric assist bicycle for the signboard has a great merit in terms of convenience.

  Therefore, the present invention aims to solve the above problem by using the battery of the electrically assisted bicycle as a battery so that it can be mounted on the self-supporting signboard very smoothly.

The present invention includes a light source, a display unit that displays advertisements or the like with light from the light source, a storage unit that can store a rechargeable battery that serves as a power source of the light source, and a doorway of the battery. A self-supporting signboard placed on the ground, wherein a slide and a bump are provided in the housing, and the slide is provided from the doorway toward the back of the housing, and the bump Is provided at the back of the slide in the housing, and the slide or the abutting portion includes an electrical contact of a circuit that conducts electricity to the light source as a housing-side electrical contact, and the battery is used for a vertically long electric bicycle. The rechargeable battery can be inserted along the slide from the entrance with the lower end of the battery first, and the lower end of the battery hits the abutting portion. , It could provide a self-contained signs it is possible to connect the electrical contacts of the battery the accommodating portion side electric contacts.
In addition, the ground here includes an indoor floor and a corridor in addition to an outdoor ground and a road surface.
The electric bicycle here includes an electric assist bicycle that assists in pedaling, and also includes an electric bicycle that drives the bicycle only with a battery.
In the present invention, the slide is inclined and extended downward from the doorway toward the back of the housing portion, and the rechargeable battery for the electric bicycle is moved from the doorway with the lower end of the battery first. A self-supporting signboard that can be inserted obliquely along the slide has been provided.
Further, according to the present invention, the accommodating portion can accommodate a battery having a handle at the upper end and an electric contact at the lower end, and the abutting portion includes the accommodating portion-side electric contact. The slide includes an inclined surface on which the battery is placed, and at least two guide portions extending along a direction in which the inclined surface extends across the inclined surface in plan view, and the guide portion includes the inclined surface Bulging upward and restricting the orientation of the battery toward the bump when inserted, and the distance between the doorway and the bump along the inclined surface is from the lower end of the battery to the bump The width between the upper end of the handle and the handle is substantially the same, the handle can be grasped from the entrance and the battery can be pulled out from the housing portion, and a caster for moving the sign is provided at the bottom of the sign We were able to provide provided free-standing sign.
In the invention of the present application, the display unit is an internally illuminated signboard that forms a translucent part that transmits light from the light source, and includes a base and at least two side wall parts erected on the base. The light source is composed of a plurality of LEDs, the side wall portions are opposed to each other with a space therebetween, and the translucent portion is disposed between the side wall portions above the base, The accommodating portion is provided between the base and the light transmitting portion between both side wall portions, and the entrance is a through-hole provided in one of the side wall portions and penetrating the side wall portion, and the entrance / exit The lower edge is disposed above the base, the abutting portion is provided integrally with the slide at the end of the slide, and the start end side of the slide is fixed to the lower end of the entrance / exit at the side wall, The end side of the slide is a self-supporting view fixed to the base. It was able to provide.
Furthermore, in the present invention, the doorway is provided with a lid capable of opening and closing the doorway, and the slide is provided with a water drain hole penetrating from the inclined surface to the back surface of the inclined surface. I was able to provide a signboard.

The present invention can supply power to a light source using a rechargeable battery of an electric bicycle. Especially on the slide, the battery can be smoothly inserted into the signboard, and the battery can be easily electrically connected.
In particular, by extending the slide from the doorway toward the back of the housing portion so as to extend downward, as shown by the dashed arrow in FIG. 4B, when the battery is placed on the slide, the inclination causes the mass of the battery to increase. A part is converted into a force that draws the slide toward the front side relative to the battery. This converted part of the force acts in the direction of escaping the signboard from the operator even if it acts in the direction opposite to the direction of escaping the signboard to which the slide is attached, that is, the direction of pulling it toward the worker side. Does not work. Therefore, the part of the converted force acts in the direction opposite to the pushing direction, and acts as a force for stopping the sign that escapes.
For this reason, in this invention, like patent document 1, the situation where a signboard escapes with the battery in the middle of insertion in the pushing direction of a battery, ie, the insertion direction of a battery, can be suppressed. In particular, according to the present invention, the situation can be suppressed in a signboard provided with a caster that is easy to move.
In other words, the inclined slide is a sign pulling force acting part that not only improves the sliding in the battery insertion direction but also converts a part of the battery load into the sign pulling direction force.
Moreover, the said slide can be made stable by withstanding the weight of the battery placed on the slide by being obliquely stretched over the side wall surface and the base, which are the stand bones of the signboard.

The inclined portion 81 is a thin metal plate. The upper surface of the inclined portion 81 is an inclined surface that carries the battery m and guides the battery m to the back of the housing portion m. The inclined surface is a smooth surface.
However, it is not necessary for the slide 8 to make the inclined surface so smooth that the battery m slides down by its own weight, as long as the operator can smoothly push it in with the handle m2. Of course, as long as the battery m and the abutting part 9 are not damaged by impact, the battery m can be slid down the inclined surface with its own weight.
In FIG. 3A, a fixing piece 85 formed by folding the thin plate of the inclined portion 81 downward is provided on the left end of the inclined portion 81, that is, on the start point side.
In the inclined portion 81, a drain hole 84 penetrating from the upper surface to the lower surface is provided near the left end of the inclined portion 81 in FIG.

The guide part 82 protrudes above the inclined surface and is a thin metal plate that restricts the direction of the battery toward the abutting part when the battery is inserted. In this example, the inclined portion 81 and the guide portion 82 are integrally formed by forming a single metal plate in a bowl shape in a U-shape in sectional view. However, the inclined portion 81 and the guide portion 82 may be formed as separate members, and may be implemented as a fixture such as bolts and nuts or integrally fixed by welding.
Further, it is assumed that only one guide portion 82 is provided, and the side of the inclined portion 81 where the guide portion 82 is not provided is close to the inner side surface of the covering portion 70 of the housing portion 7, and the inner side surface is provided. It is good also as a substitute of the guide part 82 which is not.

The pocket portion 83 is formed of a metal plate and extends upward from the right end of the inclined portion 81 shown in FIG. 3A, and extends from the upper end of the end portion 83a to the left side of FIG. 3A. It consists of a top surface part 83b and two cover parts 83c. Each cover portion 83 c covers between the top surface portion 83 b and the guide portion 82. The pocket portion 83 is formed integrally with the inclined portion 81 and the guide portion 82. However, each portion of the pocket portion 83 is formed separately from the inclined portion 81 and the guide portion 82, and is implemented as being fixed to the inclined portion 81 or the guide portion 82 with a fixture such as welding or a bolt / nut. it can. Furthermore, if the battery m can be smoothly inserted, the pocket portion 83 can be fixed to the base 2 while being separated from the inclined portion 81 and the guide portion 82.
Reference numeral 83d in FIG. 3B denotes an attachment portion to which the abutting portion 9 is attached.

As shown in FIG. 5, the fixing piece 85 is fixed to the inner surface of the side wall portion 3. More specifically, the fixing piece 85 is fixed to the lower end of the entrance / exit 31 of the side wall 3.
The fixing is done with bolts and nuts. However, the fixing can also be performed by other fixing means such as screws or other fixing means such as welding. In this example, the fixing is strengthened by welding the bolts and nuts.
The end of the inclined portion 81 on the end portion 83a side is fixed to the base 2 with bolts and nuts. This fixing can also be performed by other fixing means such as screws or other fixing means such as welding, and it is desirable to weld bolts and nuts in advance.
The length b of the inclined portion 81 of the slide 8 (FIG. 3A), more precisely, the distance between the entrance 31 and the abutting portion 9 along the inclined surface of the inclined portion 81 is the lower end of the battery m, The width between the electrical contact m1 and the upper end of the handle m2 is the same as or slightly larger.

The slide 8 has a sandwiching angle φ with the upper surface of the base 2, that is, an angle formed by the inclined portion 81 with respect to a horizontal plane (virtual plane), 0 to 60 degrees, and a sandwiching angle θ between the fixing piece 85 and the inclined section 81 is 30 degrees. It is desirable that the angle be -90 degrees.
In particular, when the slide 8 is inclined, it is preferable that the sandwiching angle φ between the inclined surface of the inclined portion 81 and the upper surface of the base 2 shown in FIG. The sandwiching angle θ of the part 81 is desirably 30 degrees to 80 degrees. This angle needs to consider the length of the inclined portion 81 corresponding to the battery m in the inclination direction.
When the battery m is 2.3 kg, the total weight of the signboard including the battery m is 27 kg, and the lateral width a of the left and right sides of the housing portion 7 is about 46 cm (FIG. 4A), it is inclined with the fixing piece 85 When the sandwiching angle θ of the part 81 is 70 degrees and the sandwiching angle φ between the inclined part 81 and the upper surface of the base 2 is 20 degrees, the battery can be mounted on the signboard very smoothly.

However, when the specification of the battery m used above is illustrated, the battery type is lithium ion, the battery configuration included in one battery m is 7 Series 5 parallel, battery capacity 9.5Ah, output voltage 25.2V, electric energy 239Wh, standard charging current 2A, charging voltage 29.1V, end-of-discharge voltage 21V, battery dimensions (vertical length x width x thickness) 211mm x 80mm × 118 mm, battery mass 2300 g.

(Bump 9)
The abutting portion 9 is provided in the back of the slide 8 in the accommodating portion 7. In this example, the abutting portion 9 is a plug provided at the end portion 83 a of the slide 8.
In this example, the abutting portion 9 serves as an abutting portion that receives the tip of the battery m and an electrical contact of the circuit that guides electricity to the light source 5, that is, an accommodating portion side electrical contact. However, the electric contact and the contact portion that physically contacts the tip of the battery m are separately provided, and the load of the battery m or the pressing force of the insertion is applied to the electric contact. Good.

(Installation of battery m)
4A and 4B, the lid 32 of the entrance / exit 31 is opened, and the battery m is moved from the entrance / exit 31 to the upper surface of the inclined portion 81 of the slide 8 with the lower end of the vertically long battery m first. Insert it diagonally. Then, the lower end of the battery m enters the pocket portion 83 and abuts against the abutting portion 9, so that the electrical contact m1 of the battery m and the abutting portion 9 can be physically and electrically connected.
The pocket portion 83 can reliably guide the battery m and prevent the battery m from falling off the slide 8.
After the battery m is mounted, the lid 32 is closed and locked. Then, by operating the switch 33, the circuit can be closed and the light source 5 can be turned on. The light source 5 may be turned on / off with a timer (not shown).
To remove the battery m, the lid 32 is opened, the handle m2 is grasped from the entrance 31 and the battery m is pulled out.

(Supplement)
In FIG. 4B, in order to avoid the complexity of the drawing, only the weight direction applied to the battery m and the force in the above-described pulling-back direction are shown, and virtual lines indicating other forces are omitted. More specifically, the gravitational force applied to the battery m includes a force that is directed obliquely downward along the inclined surface of the inclined portion 81 and a force that is opposite to the normal force that the battery m receives from the inclined surface of the inclined portion 81 (inclined). Force to hold the surface). Of the component force applied to the battery m, the force opposite to the normal force has a component in the pull-back direction.

(Example of change)
In the above embodiment, the slide 8 and the abutting portion 9 are formed integrally, but may be formed separately and attached separately in the accommodating portion.
The slide 8 is configured to place a battery on the upper surface of the inclined portion between the two guide portions. In addition, the upper sides of both guide portions, which are sides inclined downward from the entrance to the back of the housing portion, are the inclined surfaces that support the battery m by contacting the battery m, and the upper surface of the inclined portion is the battery m. It can be implemented even if it does not contact directly.
As the battery m, it is possible to use a battery m provided with the handle m2 at the upper end of the battery m or a battery m provided with the handle m2 on the side of the battery m. In this case, the battery m may be inserted into the housing portion 7 with the handle m2 facing the side opposite to the inclined portion 81 on the side of the battery m. The battery m may be provided with the electrical contact m1 at a portion other than the lower end of the battery m, for example, at the side of the battery m. Depending on the position of the electrical contact m1 of the battery m, the position of the housing-side electrical contact may be provided at a position other than the contact portion 9 of the inclined portion 81, the guide portion 82 or the pocket portion 83, not the contact portion 9. Good. Also, the battery m can be implemented by providing an accommodation portion side electrical contact at a portion other than the abutting portion 9 of the terminal portion 83a, even when the electrical contact m1 is provided at the lower end of the battery m.
The battery m is preferably a deep cycle battery. However, it does not limit the use of a starter battery that can both discharge and charge while the bicycle is running.
The water drainage hole 83a can be implemented as one provided in the end portion 83a.
Further, the slide 8 is provided with a slide portion on which the battery m is placed and pulled out to the front in conjunction with the opening of the lid body 32. When the battery m is inserted, the slide portion (not shown) is slid from the entrance 31. The battery m may be inserted by pulling it out and placing the battery m on it, and pushing the slide part back together with the battery m onto the inclined surface. In this case, it is also possible to form the slide portion as a box-shaped drawer that accommodates the battery m. When the slide portion is used as the drawer, the slide portion 32 may be provided without providing the lid body 32.
In the above-described embodiment, the double-sided signboard provided with the advertisement display unit on both the front and back sides of the signboard is illustrated, but the present invention can be implemented even with a single-sided signboard provided with the advertisement display unit on only one side.
In the above embodiment, the signboard has a rectangular shape in plan view. However, the signboard may have a triangular shape, a pentagonal shape or more, or a circular shape, or may have a shape in which straight lines and curved lines are combined.
In the above-described embodiment, the self-supporting signboard is an internally illuminated signboard, but it can also be implemented as a reflective signboard that reflects light from a light source to display an advertisement or the like. The self-supporting signboard can be implemented even if it uses a neon sign. Further, this self-supporting signboard is a matrix display device that displays information by arranging a plurality of LEDs and light bulbs in a matrix and performing dynamic lighting or static lighting, or the display is displayed as an image.
