Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wall-mounted blackboard in which hanging tools are movably and detachably attached to a frame provided on the blackboard.

[Conventional technology and its drawbacks] This type of wall-mounted blackboard has, for example,
The one described in Publication No. 43491 is already known.
This thing has a pair of ribs each having a bent piece along the upper surface of the edge frame provided at the top of the blackboard to form a guide groove that is open at both end faces, and the center part of this guide groove is curved to a medium height. In addition, a spring plate with the lower end of the hanging tool fixed is inserted into the center part of the hanging tool. It is surprisingly difficult to operate because the spring plate must be pressed flat against the elasticity of the spring and then inserted from the end face of the guide groove, and the spring plate must be moved while being pressed in order to be installed in the specified position. be. Also, due to structural constraints, thick spring boards cannot be used, and since they are curved in a medium-high manner, there is a limit to the weight of the blackboard that can be hung, and unless it is extremely light, the spring boards will deform. There is a risk.

In addition, the device described in Japanese Utility Model Publication No. 46-4975 has two pieces having holding parts for holding a writing board etc., and a hook material is fitted into the fitting part of the pieces, and the holding piece is held. The writing board, etc. is suspended by reducing the distance between the parts so that the holding part holds the writing board, etc. The holder can hold a frame provided at the upper end of a writing board or the like between the fork-shaped elastic clamps without fixing a spring plate or the like to the holder as in the prior art. However, the gripping portions, which are one ends of the pair of pieces constituting the holder, and the upper end of the frame are not provided with any special shapes such as projections and depressions for engagement or fitting. The tip of the holding portion can be hooked onto a convex portion formed at the lower end of the frame or provided with a serrated anti-slip feature. Therefore, the gripping force of the writing board etc. by the holding part is weak and cannot withstand large weight or lateral impact, and there is a drawback that the writing board etc. is likely to fall due to weight or vibration. It was hot.

[Purpose and structure of the present invention] Therefore, the present invention solves all of the above-mentioned drawbacks and provides a wall hanging device that is slidably attached to a hanging device that can be easily, reliably and firmly locked to a frame provided on the top of a blackboard, etc. The purpose is to provide a type blackboard, and for this purpose horizontal protrusions are integrally formed on both the front and back sides of the upper edge frame provided on the blackboard body, and on the other hand, bifurcated protrusions are formed on the mounting piece. A hanging tool is formed by consecutively connecting clamps having elastic properties, each of which has a locking piece protruding from the inside of the front piece and two upper and lower projecting pieces from the inside of the rear piece. to form a fitting part, and furthermore, these protrusions have an upper protrusion that is thicker and has a longer protrusion length than the lower protrusion, and the clamp is used to sandwich the edge frame,
Fit the protrusion on the rear side of the edge frame into the fitting groove on the rear piece, and lock the protrusion on the front side of the edge frame with the locking piece on the front piece to slidably attach the hanging tool. It is composed of

[Function] When the clamp of the hanging tool is fitted into the edge frame from above using its elasticity, a strong biasing force is applied to the edge frame from both the front and back sides, and it also fits into the protrusion of the fitting groove. The upper protruding piece, which is thicker and has a longer protruding length, comes into contact with the upper end surface of the edge frame and prevents it from tilting forward. On the other hand, in the case of a backward tilting force, the rearward tilting is prevented by the force of locking the protrusion of the locking piece and the contact of the upper protrusion with the upper end surface of the edge frame. As a result, the hanging tool is reliably locked to the frame without fear of falling off in either the front or back direction, so even heavy blackboards and the like can be hung without falling.

[Example] An example of the present invention will be described below with reference to the drawings. On the upper edge of the edge frame 2 attached to the side edge of the blackboard body 1, horizontal protrusions 3 and 4 are provided on both the front and back sides, respectively, and a groove 5 is formed in the lower part of the protrusion 3 on the front side. .

Reference numeral 6 denotes a hanging tool formed by a plate-shaped mounting piece 7 having a required width and a forked elastic clamp 8, and a nail hole 9 is opened in the mounting piece 7. be. The clamp 8 is composed of a front piece 8a that protrudes forward in a curved manner at the lower part of the attachment piece 7, and a rear piece 8b formed to extend the attachment piece 7.
The locking piece 1 is made to protrude inward from the lower end of the front piece 8a.
0 is provided horizontally, and a fitting groove 11 that fits into the protrusion 4 is provided at the lower end of the rear piece 8b. This fitting groove 11 has a lower projecting piece 1 facing the locking piece 10.
2 and an upper protrusion 13 which is thicker than the lower protrusion 12 and has a longer protrusion length.

Next, the attachment of the hanging tool 6 formed in this manner to the blackboard will be explained. Fit the clamp 8 of the hanging tool 6 into the edge frame 2 from above using its elasticity, first fit the fitting groove 11 of the rear piece 8b into the protrusion 4 on the rear side of the edge frame 2, and then By tilting the hanging tool 6 forward, allowing the locking piece 10 of the front piece 8a to elastically cross over the protrusion 3, and engaging the tip with the groove 5 to support the protrusion 3. Installing.

In this installed state, the clamp 8 is elastic and exerts a biasing force that strongly clamps the edge frame 2 from both front and rear sides, and also has sufficient strength and thickness to maintain the fitted state in the protrusion 4 of the fitting groove 11. The upper protruding piece 13 formed with a long protruding length comes into contact with the upper end surface of the edge frame 2 and prevents it from tilting forward.
On the other hand, in response to a force that tilts backwards, the force of locking the protrusion 3 of the locking piece 10 and the contact of the upper protrusion piece 13 to the upper end surface of the edge frame 2 prevent the force from tilting backwards. It maintains a secure mounting condition at all times, exerts a strong hanging force, and can sufficiently withstand the weight of the blackboard without fear of failure.

[Effects of the invention] As described above, the wall-mounted blackboard of the invention uses the locking pieces and the fitting grooves provided on the elastic fork-shaped clamp of the hanging tool to secure the front and back sides of the blackboard frame. In addition to locking and fitting the protrusions provided on the sides, the elasticity described above exerts a biasing force that strongly clamps the edge frame, thereby exerting sufficient force to hang and hold the blackboard, even with heavy blackboards. Don't fall. Furthermore, the edge frame of the hanging tool can be slidably moved in the left-right direction, and the hanging tool can be hung from a wall by freely changing its position with a single touch operation.

Furthermore, the hanging tool used in the present invention is not limited to blackboards, but is versatile enough to be used to hang bulletin boards, advertising boards, picture frames, various types of panels, and the like.
